The cutting machine is suitable for the cutting of Chinese medicinal herbs including rhizomes,fruitages,leaves,and grasses etc before it being fine processed,grinded or extracted,as well as for the cutting process of foodstuff(sliced fruit,preserved fruit),aquatic products(sliced kelp),tobacco leaves,and tea leave etc.This slicing machine is composed of motor, variable speed mechanism, tool rest, step and retreat material, adjustable tool rest machinery and so on. Due to the use of advanced step feeding, so that the cut of the sheet shape uniform, can freely control the feeding distance, will not cause the material extrusion knife bad situation. Due to the reasonable layout, the machine is easy to operate, light appearance, light weight. This machine is mainly composed of two parts, such as conveying and cutting medicine, machinery and so on.

It can convert the gravity acting on the measured object into a quantifiable output signal in a certain proportion. Taking into account the impact of gravity acceleration and air buoyancy on the conversion of different locations, the performance indicators of the load cell mainly include linear error, hysteresis error, repeatability error, creep, zero temperature characteristics and sensitivity temperature characteristics. In various weighing and mass measurement systems, integrated errors are often used to comprehensively control the accuracy of the sensor, and the integrated error band is linked to the scale error band (Figure 1) in order to select the weight corresponding to an accuracy scale. sensor. The OIML stipulates that the error band δ of the sensor accounts for 70% of the error band Δ of the scale, the linearity error of the load cell, the lag error, and the error due to the effect of temperature on the sensitivity within the specified temperature range. The sum cannot exceed the error band δ. This allows the manufacturer to adjust the individual components that make up the total error in the measurement to obtain the desired accuracy.
The error of the load cell is mainly caused by nonlinear error, hysteresis error, repetitive error, creep, zero-point temperature additional error, and additional output temperature error. The accuracy level of the load cell is divided into four levels: A, B, C, and D. Different levels have different error ranges. Class A sensors have the highest requirements. The number behind the level indicates the calibration index value, and the larger the number, the better the sensor quality. For example: C2 represents C level, 2000 verification divisions; C5 represents C level, 5000 verification divisions. Obviously C5 is higher than C2. The commonly used sensors are C3 and C5. These two types of sensors can be used to produce electronic scales with an accuracy class of Class III.
In order to apply the installation requirements of various weighing instruments, the load cell has been constructed in various forms, and the name of the sensor is often called according to its shape. Such as bridge sensors (mainly used for truck scales), cantilever beams (ground scales, hopper scales, truck scales), columns (vehicle scales, hopper scales), box (table scales), S-type (hopper scales) and so on. A weighing device carrier is often provided with a variety of sensor configurations. If the sensor is properly selected, it is very helpful for the improvement of the performance of the weighing device. Resistance strain-type load cells have many specifications ranging from a few hundred grams to hundreds of tons. When selecting the weighing sensor range, it is determined according to the maximum weighing scale of the weighing instrument used. Its empirical formula is:
Total sensor load (maximum allowable load per sensor X number of sensors) = 1/2 to 2/3 of the scale's maximum capacity.

The application of anatomical hanging scale weighing sensor The weighing sensor is a force-electricity conversion device that can convert gravity into an electrical signal and is a key component of the hanging scale. It relates to the sensor's ability to work properly, its safety and longevity, and even the reliability and safety of the entire scale.
