Description

Technical Field

[0001] The invention relates to the technical field of cutting devices, and in particular to a linear reciprocating medicine cutting machine. Background Art

[0002] There are many raw materials in traditional Chinese medicine that need to be processed before they can exert their maximum medicinal properties. In order to improve the efficacy, many Chinese medicinal materials need to be cut into slices for subsequent processing, especially some stick-shaped medicines are often cut into slices. The machine used for slicing is called a Chinese medicine slicer. Traditional slicers place the medicinal materials on a conveyor, fix the slicing mechanism, and transport the medicinal materials to the slicing mechanism through the conveyor to achieve the slicing operation.

[0003] A Chinese patent document with the authorization announcement number CN105751271B discloses a medicinal material slicer. It solves technical problems such as unreasonable design of the prior art. The medicinal material slicer includes a frame and a medicinal material slicing mechanism arranged at one end of the frame, a feeding platform is provided at the feeding end of the medicinal material slicing mechanism, a feeding trough with one end connected to the medicinal material slicing mechanism is provided on the feeding platform, a discharging hopper is provided at the discharging end of the medicinal material slicing mechanism, the medicinal material slicing mechanism includes a cutter that can be lifted and lowered in a vertical direction for medicinal material slicing, the cutter is detachably mounted on a knife holder, and the knife holder is connected to a driving mechanism that can drive the knife holder to lift and lower vertically.

[0004] During the slicing process, the existing slicer is not convenient to fix because the medicinal materials have different sizes and irregular shapes. When the cutter falls to cut a slice from the medicinal material, the conveyor transports the medicinal material forward for a distance. When the cutter is about to fall again to slice, the position of the medicinal material may change because the medicinal material is not fixed. After the cutter falls again to slice, the thickness of the two ends of the cut slice is uneven. Summary of the invention

[0005] The invention provides a linear reciprocating medicine cutting machine, aiming to solve the problem in the related art that the position of medicinal materials changes during slicing, resulting in uneven thickness at both ends of the slices.

[0006] A linear reciprocating medicine cutting machine comprises a conveyor belt and a cutter assembly arranged above the conveyor belt, guide chains are coaxially installed on both sides of the conveyor belt, a guide bar is fixedly installed on each link of the guide chain, and a slot is formed between the two guide bars, and the cutter assembly comprises: Two cutters, with guide blocks matching the slots fixedly arranged at the front and rear ends of the cutters; Two docking seats are respectively arranged at the front and rear ends of the cutter, and a limiting groove is provided on the docking seat. The width of the limiting groove in the left and right direction is equal to the sum of the widths of the guide strip and the two slots. The limiting groove runs through the bottom surface of the docking seat and the side close to the cutter. A clearance groove is provided at the right end of the top of the limiting groove. The width of the clearance groove in the left and right direction is greater than the width of the guide block. A one-way mechanism, installed at the left end of the bottom of the limit slot, is used to limit the guide block from being separated from the bottom of the limit slot; The toggle mechanism is used to toggle the guide block located at the left end of the limit slot to the right end after the guide block is separated from the slot; Two driving devices, the telescopic ends of the driving devices are connected to the docking seats in a left-right sliding manner, and an elastic member is installed between the two.

[0007] The effect is that the cutter at the right end cuts into the medicinal material to a certain depth to fix the position of the medicinal material, and the cutter at the left end cuts down, thereby avoiding uneven thickness at both ends of the slice due to changes in the position of the medicinal material during slicing. At the same time, since there is a small gap between the cutter at the right end and the conveyor belt, when the cutter at the left end is lifted, if the sliced ​​tablets flip over, it is difficult to enter under the cutter at the right end, thereby greatly avoiding the tablets from being cut again to form fragments.

[0008] Preferably, the bottom surface of the guide block and the bottom end of the cutter are located at the same height.

[0009] Preferably, the height of the slot is greater than the height of the cutter, so that the left cutter can completely pass over the right cutter after leaving the slot.

[0010] Preferably, the one-way mechanism includes an installation groove opened on the left side wall of the limit groove, and a rotating plate is elastically hinged at the bottom of the installation groove. When the bottom surface of the rotating plate abuts against the guide block, the rotating plate rotates counterclockwise into the installation groove, allowing the guide block to pass through the bottom of the rotating plate.

[0011] Preferably, the toggle mechanism comprises a second cylinder mounted on the docking seat, a toggle rod which can abut against the left side of the guide block is mounted on the piston end of the second cylinder, and the toggle rod moves when the second cylinder is started, thereby toggling the guide block.

[0012] Preferably, the driving device is a vertically mounted cylinder 1, a guide seat is fixedly mounted on the piston end of the cylinder 1, and a guide rod slidably connected to the guide block is fixedly mounted on the docking seat.

[0013] Preferably, a limiting strip is provided on a side of the limiting groove away from the cutter, and a notch adapted to the limiting strip is provided on the guide block.

[0014] Preferably, the movement speed of the conveyor belt is v, the width of the guide bar is L, the width of the slot is l, and the frequency of movement of the drive device is f=v / (L+l), so that the docking seat can maintain the same relative position with the slot inside it.

[0015] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. The cutter on the right cuts into the medicinal material to a certain depth to fix the position of the medicinal material, and the cutter on the left cuts down, so as to avoid uneven thickness at both ends of the slice due to the change of the position of the medicinal material during slicing; 2. When the cutter on the left is raised, if the sliced ​​tablet flips over, it will be difficult for it to enter under the cutter on the right, preventing the tablet from being cut again to form fragments.

[0026] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] like Figure 1 As shown, a linear reciprocating medicine cutting machine includes a conveyor belt 1 and a cutter assembly 2. The cutter assembly 2 is arranged above the conveyor belt 1. The conveyor belt 1 drives the medicine to move, and the cutter assembly 2 reciprocates to slice or segment the medicine.

[0028] The conveyor belt 1 includes a baffle 11, a separator plate 12, a belt 13, two guide chains 14 and a driving frame 15. The guide chain 14 and the belt 13 are arranged side by side, and the two ends are coaxial, so that the movement direction and path of the two are the same. The driving frame 15 is used to drive the guide chain 14 and the belt 13 to move synchronously. The baffle 11 is arranged at the rear of the cutter assembly 2 to prevent the cut tablets from approaching the front and rear ends of the belt 13. The separator plate 12 is arranged on the right side of the cutter assembly 2 to form a plurality of material troughs for separating materials.

[0029] like Figure 2 As shown, the guide chain 14 is formed by a plurality of chain links connected end to end, and a guide bar 141 is fixedly mounted on each chain link, and a slot is formed between two guide bars 141 .

[0030] like Figure 3-Figure 7 As shown, the cutter assembly 2 includes two one-way mechanisms 21, two toggle mechanisms 22, two cutters 23, two docking seats 24 and two driving devices 25. The two docking seats 24 are respectively arranged at the front and rear ends of the cutter 23. The one-way mechanism 21 and the toggle mechanism 22 are both arranged on the docking seats 24. The driving device 25 drives the docking seats 24 to rise and fall, thereby controlling the two cutters 23 to move alternately. The two cutters 23 are divided into a cutter 23A and a cutter 23B, and the steps of relative movement of the two cutters 23 are as follows: S1, the cutter 23A is located on the left side of the cutter 23B and cuts into the medicinal material to a certain depth, and the cutter 23B is against the upper surface of the medicinal material; S2, the cutter 23A and the cutter 23B move downward at the same time, the cutter 23A cuts the medicinal material, and the cutter 23B cuts into the medicinal material to a certain depth but does not cut it; S3, the cutter 23A moves upward relative to the cutter 23B until the blade of the cutter 23A reaches above the top of the cutter 23B; S4, the cutter 23A moves backward to the right side of the cutter 23B; S5, the cutter 23A moves downward against the upper surface of the medicinal material; S6, the cutter 23B and the cutter 23A move downward at the same time, the cutter 23B cuts the medicinal material, and the cutter 23A cuts into the medicinal material to a certain depth but does not cut it; The above steps are repeated in a cycle to slice the medicinal material.

[0031] In order to complete the above steps, the cooperation between the various components in the cutter assembly 2 is further described below; like Figure 4-Figure 9 As shown, the cutter 23 includes a blade body 231 and two guide blocks 232. The two guide blocks 232 are fixedly arranged at the front and rear ends of the blade body 231 respectively. The bottom surface of the guide block 232 is at the same height as the bottom end of the blade body 231, and the guide block 232 is adapted to the slot. The guide block 232 is provided with an annular protrusion that contacts the inner side of the guide strip 141, so that the cutter 23 slides up and down along the height direction of the slot, and the height of the blade body 231 is less than the height of the slot, so that in the above steps S3 and S4, the left cutter 23 can completely pass over the right cutter 23; The driving device 25 includes a cylinder 251, a guide seat 252, a guide rod 253 and an elastic member 254. The piston end of the cylinder 251 is fixedly mounted on the guide seat 252. The guide rod 253 is fixedly mounted on the docking seat 24 and is slidably connected to the guide seat 252. An elastic member 254 (preferably a spring) is installed between the docking seat 24 and the guide seat 252. Since the conveyor belt 1 is constantly moving, when the guide block 232 on the cutter 23 is inserted into the slot, the docking seat 24 moves synchronously with the conveyor belt 1, thereby compressing the spring. When the guide block 232 on the cutter 23 is separated from the slot, the spring resets the docking seat 24. Assume that the movement speed of the conveyor belt 1 is v, the width of the guide bar 141 is L, the width of the slot is l, and the expansion and contraction frequency of the cylinder 1 251 is f=v / (L+l), so that when the cylinder 1 251 is extended, the docking seat 24 can maintain the same relative position with the slot inside it.

[0032] A limiting groove 241 is provided on the docking seat 24, and the limiting groove 241 passes through the bottom surface of the docking seat 24 and a side close to the cutter 23. A clearance groove 242 is provided at the right end of the top of the limiting groove 241. The width of the limiting groove 241 in the left-right direction is equal to the sum of the widths of the guide strip 141 and the two slots. Therefore, when the two cutters 23 are inserted between the slots, the guide blocks 232 on the two cutters 23 are respectively located at the left and right ends of the slots, and the width of the clearance groove 242 in the left-right direction is greater than the width of the guide block 232, so that the guide block 232 located at the right end can enter the clearance groove 242. Therefore, in the above steps S2 and S6, the docking seat 24 descends to form a height difference between the two cutters 23, so that the cutter 23 on the left cuts the medicinal materials.

[0033] The one-way mechanism 21 includes a mounting groove 211 and a rotating plate 212. The mounting groove 211 is provided on the left side wall of the limiting groove 241. One end of the rotating plate 212 is elastically hinged at the bottom of the mounting groove 211 through a spring and a rotating shaft. When the bottom surface of the rotating plate 212 abuts against the guide block 232, the rotating plate 212 rotates counterclockwise and is received into the mounting groove 211. Thus, in the above step S3, the docking seat 24 rises to drive the left cutter 23 to rise. In the above step S5, the docking seat 24 descends to make the guide block 232 on the left cutter 23 abut against the bottom surface of the rotating plate 212, so that the guide block 232 on the left cutter 23 enters the limiting groove 241.

[0034] The toggle mechanism 22 includes a second cylinder 221 and a toggle rod 222. The second cylinder 221 is installed on the docking seat 24. The toggle rod 222 is fixedly installed on the piston end of the second cylinder 221. A limiting strip 243 is arranged on the side of the limiting groove 241 away from the cutter 23. A notch adapted to the limiting strip 243 is opened on the guide block 232.

[0035] In the above step S4, the bottom of the guide block 232 in the cutter 23A abuts against the rotating plate 212, the cylinder 221 is started, the toggle rod 222 pushes the guide block 232 in the cutter 23A to move to the right, and the limiting strip 243 enters the notch, so that the cutter 23 remains vertical until the guide block 232 moves to the right end of the limiting slot 241. At this time, the guide block 232 in the cutter 23B is located below the left end of the limiting slot 241. Finally, the cylinder 221 drives the toggle rod 222 to reset.

[0036] Working steps (steps S1-S6 below correspond to steps S1-S6 above): S1, the cutter 23A is located on the left side of the cutter 23B and cuts into the medicinal material to a certain depth, and the cutter 23B is against the upper surface of the medicinal material; S2, the cylinder 251 drives the docking seat 24 to descend, the left end of the limit groove 241 abuts against the cutter 23A, and the cutter 23B enters the clearance groove 242, so that the cutter 23A moves downward relative to the cutter 23B to cut the medicinal material, and the cutter 23B cuts into the medicinal material to a certain depth but does not cut it; S3, the cylinder 251 drives the docking seat 24 to rise, and the rotating plate 212 abuts against the cutter 23A, so that the cutter 23A moves upward relative to the cutter 23B until the blade of the cutter 23A reaches above the top of the cutter 23B; S4, the second cylinder 221 is started, and the toggle rod 222 pushes the cutter 23A to move rightward until the guide block 232 in the cutter 23A moves to the right end of the limiting groove 241, and the guide block 232 in the cutter 23B is located below the left end of the limiting groove 241; S5, the cutter 23A slides downward along the slot against the upper surface of the medicinal material; S6, the cylinder 251 drives the docking seat 24 to descend, the left end of the limiting groove 241 abuts against the cutter 23B, and the cutter 23A enters the clearance groove 242, so that the cutter 23B moves downward relative to the cutter 23A to cut the medicinal material, and the cutter 23A does not move; Repeat the above steps in a loop.

[0037] Through the above steps, the cutter 23 at the right end cuts into the medicinal material to a certain depth to fix the position of the medicinal material, and the cutter 23 at the left end cuts down, thereby avoiding uneven thickness at both ends of the slice due to changes in the position of the medicinal material during slicing. At the same time, since there is a small gap between the cutter 23 at the right end and the conveyor belt 1, when the cutter 23 at the left end is lifted, if the sliced ​​tablets are turned over, it is difficult to enter under the cutter 23 at the right end, thereby greatly avoiding the tablets from being cut again to form fragments.

[0038] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
