Description

Technical Field

[0001] The utility model relates to the field of medicinal material processing machinery, and particularly relates to a medicinal material slicing machine. Background Art

[0002] China's medicinal material resources are very rich. There are more than a thousand kinds of medicinal materials operated and circulated by local medicinal material companies. Except for a few mineral medicines and some animal and plant medicinal materials with hard textures that are not suitable for cutting, nearly 90% of Chinese medicinal materials need to be processed by cutting. The cut shapes include thin slices, thick slices, sections, strips, grains, etc., which are used for the extraction and feeding in the production of Chinese patent medicines, the rough processing before the pulverization of medicinal materials, the semi-finished products of the processing of prepared slices of Chinese crude drugs, etc. Among them, about 70% of the medicinal materials need to be cut into slice shapes, including the slicing processing before cutting into strip and granular slice shapes. A cutting machine is a device that can cut vegetable medicinal materials into inner slices, sections, strips, etc. and can adjust the thickness. The advent of the cutting machine has replaced the original manual cutting operation and improved the processing efficiency of medicinal materials. Therefore, the cutting machine is a widely used processing device in the cutting production of medicinal materials.

[0003] According to different slicing methods, slicing machines are divided into two major categories: rotary type and reciprocating type. The cutter of the reciprocating slicing machine makes a linear reciprocating motion. This motion mode enables the reciprocating slicing machine to provide continuous slicing action when processing materials. The main characteristics of the reciprocating slicing machine include smooth cut, good slice shape, the whole machine being suitable for water flushing, easy to operate, easy to maintain, and no pollution to materials, etc. The cutter of the rotary slicing machine makes a circular motion. This motion mode enables the rotary slicing machine to provide a relatively uniform slicing force during the slicing process. Compared with the reciprocating slicing machine, the rotary slicing machine has higher working efficiency and faster slicing speed. However, compared with the reciprocating slicing machine in terms of the slicing effect, the cut of the medicinal material at the slicing part of the rotary slicing machine is slightly rough.

[0004] The cutter of the reciprocating slicing machine needs to be driven by reciprocating motion mechanisms such as telescopic cylinders and double hinges, so as to drive the cutter of the reciprocating slicing machine to make a linear reciprocating motion. Compared with the rotary mechanism, since the cutter is prone to impact during the reciprocating motion process, the uniformity of the slicing force provided by the reciprocating motion mechanisms such as telescopic cylinders and double hinges is poor, which affects the stability of slicing and increases the energy consumption of the sliced medicinal materials. Moreover, the slicing efficiency of the reciprocating slicing machine is also lower than that of the rotary slicing machine, making the slicing process take more time. Therefore, it is necessary to optimize and improve the transmission mechanism of the reciprocating slicing machine, which can not only reduce the energy consumption of slicing, but also improve the slicing efficiency and help to speed up the slicing operation process. Summary of the Invention

A through hole is formed at the top of the protective shell 7. The through hole is movably sleeved on the drive shaft of the drive motor 4. The through hole is located above the turntable 10 to facilitate the drive motor 4 to drive the gear 8 and the rotating shaft 9 to operate.

[0030] Please refer to again Figure 2 and 3 , a scraper 31 is obliquely arranged on one side of the rotary cutting mechanism away from the stepping motor 3. The top of the scraper 31 is in contact with the top surface of the conveyor belt 2. A support rod 32 is arranged at the bottom of the scraper 31. The bottom of the scraper 31 is installed in the middle of the support rod 32. U-shaped frames 33 are movably sleeved on both sides of the support rod 32 respectively. The U-shaped frames 33 are installed on the frame 1. Nuts 34 are threadedly sleeved on the support rod 32 outside the U-shaped frames 33. The support rod 32 is clamped on the U-shaped frames 33 through the nuts 34, so as to use the scraper 31 to scrape the conveyor belt 2 to prevent the sliced medicinal materials from being adsorbed on the conveyor belt 2.

[0031] The usage method of this product is as follows: As Figures 1 to 8 shown, first, place the box for collecting sheet-shaped medicinal materials under the scraper 31, so that the sheet-shaped medicinal materials after the slicing process of this product fall into the box to facilitate the collection of sheet-shaped medicinal materials; then, according to the size of the medicinal materials, use the bolt 27 to adjust the fixing position of the fixing sleeve 25, so that the pressing roller 23 can press the medicinal materials on the conveyor 2, and by controlling the telescopic amount of the telescopic cylinder 17, the rotation angle of the guide plate 15 can be controlled, so as to conveniently guide the medicinal materials to be conveyed towards the slicing areas of the two cutting knives 6. Then, before using this product, it is necessary to pre-run this product. First, start the stepping motor 3 to drive the conveyor belt 2 to run, and then start the drive motor 4. Through the gear 8, the rotating shaft 9, the turntable 10 and the rotating rod 11, drive the two cutting knives 6 to reciprocate for slicing actions. Then, after the pre-run of this product is stable, use the conveying equipment to place the medicinal materials to be sliced on the conveyor belt 2 in sequence, so as to slice the medicinal materials with the two reciprocatingly swinging cutting knives 6 and use the scraper 31 to scrape the conveyor belt 2, so that the scraped sheet-shaped medicinal materials fall into the box to complete the slicing process.

And by controlling the driving motor 4 to operate, two gears 8 drive the rotating shaft 9 and the turntable 10. Since the rotating rod 11 is eccentrically arranged on the turntable 10, and the rotating rod 11 is movably sleeved in the guiding grooves 12 respectively opened on the inner side of the cutter 6, the inner side of the cutter 6 is driven to swing reciprocally up and down. Then, since the outer side of the cutter 6 is hinged to the frame 1, during the operation of the cutter 6, the cutter 6 swings cyclically around the hinge point between the outer side of the cutter 6 and the frame 1, so as to facilitate slicing the medicinal materials conveyed on the conveyor belt 2. Moreover, the two rotating rods 11 are respectively arranged on both sides of the two turntables 10. For the rotating shaft 9, when the cutter 6 is in an unloaded state, the forces on both sides of the rotating shaft 9 are balanced, so as to facilitate the stable driving of the driving motor 4 to rotate the rotating shaft 9. Therefore, when using the cutter 6 to slice the medicinal materials conveyed on the conveyor belt 2, the force on the driving motor 4 can also be reduced, so as to reduce the energy consumption of slicing the medicinal materials. And by increasing the number of cutters 6, the slicing efficiency can be improved, thus helping to accelerate the process of the slicing operation.
