Abstract
Description
Technical Field
[0001] This utility model relates to the field of pill-making machine technology, and in particular to a fully automatic pill-making equipment. Background Technology
[0002] In the field of Traditional Chinese Medicine (TCM), many medicinal pills with special effects are characterized by high moisture content, such as the common navel pills. These pills are generally made from a variety of Chinese medicinal herbs through specific processing and mixing techniques. The moist, sticky state helps the medicine exert its effects, and for externally applied navel pills, it also allows them to adhere better to the skin, promoting transdermal absorption. However, it is precisely this moist, sticky characteristic that presents numerous challenges to the pill preparation process.
[0003] Extrusion granulation is a common granulation method. Under the pressure of rollers, specially prepared herbal granules are extruded to efficiently form particles of a specific shape and size. However, extrusion granulation is severely unsuitable for herbal pills with high moisture content. Another common granulation method involves first extruding the herbal material into strips, then equally dividing and rounding them. This method is also unsuitable for preparing pills with high moisture content. Wet and sticky herbal materials are difficult to uniformly form into strips after extrusion, and they tend to stick together again after being cut.
[0004] To adapt to the preparation of wet pills, this invention proposes a pill preparation equipment for the efficient processing of pills with high humidity. Utility Model Content
[0005] Therefore, in view of the above problems, this utility model proposes a fully automatic pill preparation equipment for improving the efficiency of wet pill preparation.
[0006] To solve the above-mentioned technical problems, the solution adopted by this utility model is as follows: a fully automatic pill preparation equipment, including a base plate, a spiral discharge cylinder vertically arranged in the middle of the base plate, two symmetrical discharge ports respectively opened on the left and right sides of the lower end of the spiral discharge cylinder, two discharge pipes horizontally welded on the discharge ports, and extrusion pipes horizontally detachably connected to the discharge ends of the two discharge pipes, a plurality of extrusion holes evenly spaced at the lower end of the extrusion pipe, a sliding cutting cylinder for cutting the extruded material sleeved on the outer wall of the extrusion pipe, the inner wall of the sliding cutting cylinder fitting against the outer wall of the extrusion pipe, a cutting hole corresponding to the extrusion hole and not smaller than the diameter of the extrusion hole opened at the lower end of the sliding cutting cylinder, the outer wall of the extrusion pipe and the surface of the cutting cylinder are both sprayed with an anti-stick coating, and a sliding drive device is respectively provided on the base plate for driving the two sliding cutting cylinders to slide linearly along the outer wall of the extrusion pipe to cut the material.
[0007] A further improvement is that a receiving roller is provided below the extrusion tube to increase the roundness of the cut material. The receiving roller is tilted and fixed to the base plate. Several partitions are erected on the receiving roller to prevent the material from sticking together again. The upper surface of the receiving roller and the surface of the partitions are coated with an anti-stick coating.
[0008] A further improvement is made to the sliding drive device, which includes a mounting bracket, a mounting box, a motor, a drive disk, and a U-shaped drive block. The mounting bracket is erected on the base plate outside the extrusion tube. The mounting box is fixedly mounted on the top of the mounting bracket. The housing of the motor is fixedly mounted on the top surface of the mounting box. The rotating shaft of the motor passes through the inner wall of the mounting box and is rotatably mounted on the bottom surface of the mounting box. The drive disk is eccentrically fixedly sleeved on the rotating shaft of the motor. The U-shaped drive block is vertically movably mounted on the mounting box. The inner side of the mounting box on one side of the extrusion tube has a first guide hole for the two free ends of the U-shaped drive block to pass through and guide the U-shaped drive block to slide horizontally and linearly. A slider is provided in the middle of the bottom surface of the U-shaped drive block. An annular groove is provided on the side wall of the drive disk for the slider to be engaged and for the slider to be restricted from detaching. The slider is slidably mounted in the annular groove. The outer end of the extrusion tube is detachably fixed to the inner side of the mounting box. The two free ends of the U-shaped drive block are detachably fixed to the sliding cutting cylinder.
[0009] A further improvement is that an inner flange and an outer flange for disassembly and fixing are integrally fixed on the inner and outer ends of the extrusion tube, respectively. The inner flange is bolted to the free end face of the discharge tube, and a sealing ring is pressed between the inner flange and the free end face of the discharge tube. The outer flange is bolted to the inner side of the mounting box, and a second guide hole corresponding to the first guide hole is provided on the outer flange.
[0010] A further improvement is that: the upper end of the sliding cutting cylinder has an axial opening for easy covering on the extrusion tube; both ends of the sliding cutting cylinder are provided with upper fixing lugs on both sides of the upper opening; the lower end of the sliding cutting cylinder on one side of the U-shaped drive block is provided with a lower fixing lug; both the upper and lower fixing lugs are provided with a first locking hole for bolts to pass through and lock; and the two free ends of the U-shaped drive block are provided with a second locking hole corresponding to the first locking hole for bolts to pass through.
[0011] A further improvement is that the sliding cutting cylinder is made of a plastic sheet.
[0012] A further improvement is that the sliding cutting cylinder has a material-saving and resistance-reducing opening cut into the portion above the cutting hole and between the two upper fixed lugs.
[0013] A further improvement is that the anti-stick coating is a food-grade silicone oil coating.
[0014] By adopting the aforementioned technical solution, the beneficial effects of this utility model are: 1. A vertical cylinder is positioned in the center of the base plate, with symmetrical discharge ports on the left and right sides at its lower end. Two sets of extrusion equipment can be symmetrically arranged, significantly improving the overall pelleting efficiency compared to a single extrusion unit, thus meeting the needs of larger-scale pellet production. The extruded material is cut by a sliding cutter cylinder, resulting in a simple structure well-suited for processing pellets with high moisture content. The sliding cutter cylinder has a short reciprocating sliding path, rapid operation, and high cutting efficiency, greatly improving pellet manufacturing efficiency.
[0015] 2. The sliding cutting cylinder is driven to reciprocate through a motor, an eccentrically mounted drive disc, and a U-shaped drive block, resulting in a simple and compact structure. The U-shaped drive block slides directly against the side wall of the drive disc via the cooperation of a slider and a groove. Compared to reciprocating drive methods such as connecting rods and cylinders, this design significantly reduces the range of motion of the components. Furthermore, the motor is distributed along the longitudinal space, shortening the lateral length of the equipment and reducing the lateral space occupied by the equipment. This facilitates symmetrical distribution on both sides and improves the production efficiency of the equipment.
[0016] 3. The food-grade silicone oil coating applied to the outer wall of the extrusion tube and the surface of the sliding cutting cylinder can prevent material adhesion and provide lubrication, thereby reducing the sliding resistance of the sliding cutting cylinder.
[0017] 4. The two free ends of the U-shaped drive block are guided by the side of the mounting box and the outer flange, eliminating the need for a guide structure and simplifying the structure of the sliding drive device.
[0018] 5. The upper surface of the receiving roller and the surface of the partition are coated with food-grade silicone oil as an anti-stick coating, which effectively prevents material from sticking, ensuring that the pill blanks are formed smoothly, avoiding material waste, and facilitating equipment cleaning and maintenance.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0027] refer to Figures 1 to 7 This utility model discloses a fully automatic pill-making device, including a base plate 10. A spiral discharge cylinder 11 is vertically arranged in the middle of the base plate 10 (the spiral discharge cylinder 11 described in this embodiment is prior art and will not be described in detail here). Two symmetrical discharge ports are respectively opened on the left and right sides of the lower end of the spiral discharge cylinder 11, which is conducive to symmetrically setting two sets of extrusion equipment and improving the pill-making efficiency of the equipment. Two discharge pipes 12 are horizontally welded on the discharge ports. The internal channels of the discharge pipes 12 gradually narrow from the inside to the outside. The discharge ends of the two discharge pipes 12 are horizontally detached and connected to an extrusion pipe 13. The inner end of the internal channel of the extrusion pipe 13 is connected to the channel of the discharge pipe 12, and the outer end is closed. The lower end of the extrusion tube 13 is provided with a plurality of extrusion holes 14 at uniform intervals. The outer wall of the extrusion tube 13 is fitted with a sliding cutting cylinder 15 for cutting the extruded material. The inner wall of the sliding cutting cylinder 15 is in contact with the outer wall of the extrusion tube 13. The lower end of the sliding cutting cylinder 15 is provided with a cutting hole 16 corresponding to the extrusion holes 14 and not smaller than the diameter of the extrusion holes 14. The outer wall of the extrusion tube 13 and the surface of the cutting cylinder are both coated with an anti-stick coating, which is a food-grade silicone oil coating.
[0028] Below the extrusion tube 13 is a receiving roller 17 for increasing the roundness of the cut material. The receiving roller 17 is tilted and detachably fixed to the base plate 10. Several partitions 18 are erected on the receiving roller 17 to prevent the material from sticking together again. The upper surface of the receiving roller 17 and the surface of the partitions 18 are coated with an anti-stick coating, which is a food-grade silicone oil coating. For pellets with high moisture content, the roundness requirement is relatively low. As the pellets roll down the receiving roller 17, they gather towards the center, which helps to improve the roundness of the pellets and facilitates packaging.
[0029] The base plate 10 is provided with sliding drive devices for driving the two sliding cutting cylinders to slide linearly along the outer wall of the extrusion tube 13 for cutting material. Each sliding drive device includes a mounting bracket 20, a mounting box 21, a motor 22, a drive disk 23, and a U-shaped drive block 24. The mounting bracket 20 is triangular in shape for good stability and is bolted to the base plate 10 on the outside of the extrusion tube 13. The mounting box 21 is welded and fixed to the top of the mounting bracket 20. The housing of the motor 22 is fixed to the top surface of the mounting box 21. The rotating shaft of the motor 22 passes through the inner wall of the mounting box 21 and is fixed by bearings to rotatably mount on the bottom surface of the mounting box 21. The drive disk 23 is eccentrically fixedly sleeved on the rotating shaft of the motor 22. The U-shaped drive block 24 is vertically movable on the mounting box 21. The mounting box 21 has a first guide hole 25 on its inner side located on one side of the extrusion tube 13, through which the two free ends of the U-shaped drive block 24 pass and guide the U-shaped drive block 24 to slide horizontally in a straight line. A slider 26 is welded to the middle of the bottom surface of the U-shaped drive block 24. An annular groove 27 is provided on the side wall of the drive disk 23 for the slider 26 to be inserted into and for the slider 26 to be restricted from detaching. The cross-section of the slider 26 and the groove is T-shaped or more than half of a hemisphere. The slider 26 is slidably disposed in the annular groove 27. The outer end of the extrusion tube 13 is detachably fixed to the inner side of the mounting box 21. The two free ends of the U-shaped drive block 24 are detachably fixed to the sliding cutting cylinder 15.
[0030] An inner flange 28 and an outer flange 29 for disassembly and fixing are integrally fixed to the inner and outer ends of the extrusion tube 13, respectively. The inner flange 28 is bolted to the free end face of the discharge tube 12, and a sealing ring 30 is pressed between the inner flange 28 and the free end face of the discharge tube 12. The outer flange 29 is bolted to the inner side of the mounting box 21, and a second guide hole 31 corresponding to the first guide hole 25 is provided on the outer flange 29. The flanges at both ends of the extrusion tube 13 facilitate the replacement of the extrusion tube 13, and different diameter extrusion holes 14 can be replaced according to the required size of the pellets, improving the versatility of the equipment.
[0031] The upper end of the sliding cutting cylinder 15 has an axial opening for easy mounting on the extrusion tube 13. The sliding cutting cylinder 15 is made of a plastic sheet that can deform to facilitate its mounting and fixation on the surface of the extrusion tube 13. Upper fixing lugs 32 are integrally formed at both ends of the sliding cutting cylinder 15 on either side of the upper opening. Lower fixing lugs 33 are integrally formed at the lower end of the sliding cutting cylinder 15 on one side of the U-shaped drive block 24. Both the upper and lower fixing lugs 32 and 33 have first locking holes 34 for bolts to pass through and lock. The two free ends of the U-shaped drive block 24 have second locking holes 35 corresponding to the first locking holes 34 for bolts to pass through. A material-saving and resistance-reducing opening 36 is cut into the portion of the sliding cutting cylinder 15 above the cutting hole 16 and between the two upper fixing lugs 32 to reduce the sliding resistance of the sliding cutting cylinder 15.
[0032] Instructions for using fully automated pill preparation equipment: Material processed from various Chinese medicinal herbs is fed into the spiral discharge cylinder 11. The rotating propeller inside the spiral discharge cylinder 11 pushes the material downward, causing it to be squeezed into the extrusion pipe 13 along the discharge pipe 12, and then extruded from the extrusion hole 14. The extruded material is simultaneously located in the cutting hole 16. After the material is extruded at a set time, the rotating shaft of the motor 22 drives the drive disk 23 to rotate one revolution, thereby driving the sliding cutting cylinder 15 to slide back and forth once, cutting off and resetting the extruded material. The cut material falls downward onto the receiving roller 17 and rolls downward along the inclined receiving roller 17.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions above are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
