Description

Technical Field

[0001] This invention belongs to the field of catering equipment technology, and in particular relates to a novel automatic chopstick disassembly machine. Background Technology

[0002] The disposable chopsticks commonly used in the catering industry are generally made from a large amount of wood processed using standard techniques. This consumes a lot of wood, which seriously damages the environment. In addition, ordinary chopsticks are generally of a fixed length, which cannot meet the diverse needs of different diners in different dining environments.

[0003] This situation spurred the widespread use of modular chopsticks. Existing modular chopsticks consist of a plastic part and a bamboo part. The plastic part has a square cross-section, while the bamboo part has a circular cross-section. The end of the plastic part connects to the end of the bamboo part via a connecting tube, the inner wall of which is threaded. In use, the plastic part serves as the grip, and the bamboo part is used for picking up food.

[0004] After using a set of chopsticks, the used bamboo part needs to be removed, the plastic part cleaned, and then a new bamboo part installed. Current production processes rely on manual removal of the bamboo part from the insert, which is laborious and time-consuming. Furthermore, manual removal can easily detach the insert from the plastic part, preventing the chopsticks from being reused and resulting in a high scrap rate. Therefore, automatic chopstick disassembly machines have emerged, such as the invention patent CN201910482983.X entitled "A High-Efficiency Fully Automatic Chopstick Disassembly Machine," which provides a high-efficiency fully automatic chopstick disassembly machine including: a base; a feeding device; a piece-by-piece transfer device; a piece-by-piece conveying device; and a chopstick disassembly device. Currently, such machines have the following drawbacks: 1. Using a cylinder to drive the disassembly mechanism results in high manufacturing costs, a high cylinder failure rate, poor stability, and low overall work efficiency. 2. These types of chopstick removers usually use a cylinder to press the chopsticks in place, but this fixation can damage the chopsticks and may even cause them to break. Summary of the Invention

[0005] This invention provides a novel automatic chopstick disassembly machine to solve the technical problems mentioned in the background section.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a novel automatic chopstick disassembly machine, comprising a platform and a piece-by-piece conveying device and a chopstick disassembly mechanism disposed on the platform. The piece-by-piece conveying device includes a material distribution mechanism and a conveying clamping mechanism. The conveying clamping mechanism includes a control chamber and a drive assembly and a push plate assembly disposed within the control chamber. The material distribution mechanism is located at the upper end of the control chamber, and the chopstick disassembly mechanism is located on one side of the control chamber. The chopstick disassembly mechanism is connected to the drive assembly via a transmission mechanism.

[0007] Furthermore, the drive assembly includes a drive motor and a drive shaft located at the lower end of the drive motor. The drive shaft is provided with a first transmission wheel, a first cam, and a second cam. The output end of the drive motor is provided with a second transmission wheel and a motor pulley located outside the second transmission wheel. The first transmission wheel and the second transmission wheel are connected by a belt drive. The motor pulley is connected to the chopstick disassembly mechanism to drive the chopstick disassembly mechanism to rotate in a circular motion. The first cam is mounted on the drive shaft and located outside the first transmission wheel. The first cam drives the chopstick disassembly mechanism through a transmission mechanism. The second cam is located in the control room and drives the conveying clamping mechanism through a push plate assembly.

[0008] Furthermore, the transmission mechanism includes a swing arm, the lower end of which is provided with a first guide wheel that contacts the first cam, one end of which is connected to the chopstick disassembly mechanism via a connecting mechanism, the end of which is away from the chopstick disassembly mechanism is provided with a first elastic element that is connected to the platform, the lower end of which is provided with a bearing fixing seat, and a rotating shaft is vertically installed in the bearing fixing seat, and the rotating shaft is connected to the swing arm.

[0009] Furthermore, the chopstick disassembly mechanism includes a punch fixing bracket and a chuck shaft fixing bracket mounted on the platform. The chuck shaft fixing bracket has a hollow chuck shaft movably disposed thereon. A punch is fixed on the punch fixing bracket. The end of the punch away from the punch fixing bracket extends into the chuck shaft. The end of the chuck shaft away from the punch fixing bracket is provided with a chuck. The chuck has a locking hole that communicates with the inside of the chuck shaft.

[0010] Furthermore, the connecting mechanism includes a fixing ring on the chuck shaft and a retainer fixed on one side of the swing arm. The fixing ring is set in the retainer by a threaded connection. A chuck shaft pulley that is connected to the motor pulley is fixed on the chuck shaft. Transmission bearings are provided on both sides of the chuck shaft fixing frame. The chuck shaft is located in the transmission bearings. The chuck shaft pulley drives the chuck shaft to rotate within the transmission bearings by the rotation of the motor pulley.

[0011] Furthermore, the push plate assembly includes a first bearing seat and a second bearing seat disposed on the platform, and a fixed shaft disposed between the first bearing seat and the second bearing seat. A transmission rod is movably disposed on the fixed shaft, and connecting rods are provided on both sides of the transmission rod. A push plate is fixed at the lower end of the connecting rod.

[0012] Furthermore, the transmission rod includes a rotating end movably mounted on a fixed shaft, and a first rod portion and a second rod portion integrally formed on both sides of the rotating end. The first rod portion and the second rod portion are inclined, and a second guide wheel is provided between the first rod portion and the second rod portion. The second guide wheel and the second cam abut against each other. The second cam controls the swing of the transmission rod through a rotating wheel. It also includes a second elastic element and a crossbar fixed in the control room. A fixing bolt is provided at the end of the first rod portion and the second rod portion away from the rotating end. The two ends of the second elastic element are respectively connected to the crossbar and the fixing bolt.

[0013] Furthermore, the control room includes a first fixed plate, a second fixed plate, and a third fixed plate that surround each other. The first fixed plate has a feeding port, and the second and third fixed plates have corresponding movable grooves on both sides. The push plate is engaged in the movable grooves on both sides and can move horizontally along the movable grooves. The push plate has at least two feeding ends on its outer side, and the feeding ends are located at the lower end of the material distribution mechanism.

[0014] Furthermore, a blocking frame is fixed to the outside of the first fixed plate, and a fixed rubber seat is fixed on the blocking frame at the corresponding position of the feeding end. A plurality of movable rubber seats are provided on the side of the push plate near the feeding end, and the movable rubber seats correspond one-to-one with the fixed rubber seats.

[0015] Furthermore, the material distribution mechanism includes a material bin located at the upper end of the control room, a material distribution shaft rotatably mounted on the control room, and a material distribution wheel located on the material distribution shaft. The material distribution wheel is located below the material bin, and a clamping plate is provided between the material distribution wheel and the material bin. The material distribution shaft and the drive shaft are connected by belt drive.

[0016] By using the above technical solution, compared with the prior art, the present invention has the following beneficial effects: 1. By setting a first cam and a second cam on the drive assembly, and setting a swing arm that contacts the first cam, and a push plate assembly that contacts the second cam, when the drive assembly is started, the first cam and the second cam on the drive assembly begin to rotate. The rotation of the second cam causes the convex surface of the second cam to contact the push plate assembly, thereby continuously driving the push plate assembly to swing left and right. When the convex surface of the second cam contacts the push plate assembly, the push plate assembly pulls the push plate inward. When the flat surface of the second cam contacts the push plate assembly, the push plate assembly pushes the push plate outward. When the push plate is pulled inward, the chopsticks in the dispensing mechanism fall into the feeding end at the front end of the push plate. The push plate assembly pushes the plate containing the chopsticks outward, thus pushing the chopsticks to the clamping position corresponding to the chopstick disassembly mechanism. At the same time, one end of the swing arm is connected to the chopstick disassembly mechanism, and the other end is fixed to the platform through the first elastic element, so that the concave and convex surfaces of the first transmission wheel and the first cam at the lower end of the swing arm respectively contact. When the first transmission wheel contacts the concave surface, the chopstick disassembly mechanism moves in the direction where the chopstick head is located, so that the clamping head on the chopstick disassembly mechanism engages with the chopstick head. When the first transmission wheel contacts the convex surface, the swing arm will drive the chopstick disassembly mechanism to move in the opposite direction, thereby pulling off the chopstick head. During this process, the motor pulley on the drive device simultaneously drives the clamping shaft pulley on the chopstick disassembly mechanism, so that the clamping shaft pulley drives the chopstick disassembly mechanism to rotate in a circle, thereby completing the disassembly of the chopstick head and handle.

[0017] 2. By installing a blocking frame on the outside of the control room, a fixed rubber seat on the inside of the blocking frame, and a movable rubber seat corresponding to the fixed rubber seat on the side of the push plate near the feeding end, the chopsticks are clamped by the fixed rubber seat and the movable rubber seat to avoid damage to the chopsticks when conveying them.

[0018] This device offers greater overall stability and efficiency, and eliminates the cost associated with using cylinders, thus addressing the technical issues of existing chopstick disassembly machines, which suffer from poor stability, low efficiency, and high cost. Attached Figure Description

[0034] like Figure 1-7 As shown: A novel automatic chopstick disassembly machine includes a platform 1 and a piece-by-piece conveying device and a chopstick disassembly mechanism disposed on the platform 1. The piece-by-piece conveying device includes a material distribution mechanism and a conveying clamping mechanism. The conveying clamping mechanism includes a control chamber 2 and a drive assembly and a push plate assembly disposed within the control chamber 2. The material distribution mechanism is located at the upper end of the control chamber 2, and the chopstick disassembly mechanism is located on one side of the control chamber 2. The chopstick disassembly mechanism is connected to the drive assembly via a transmission mechanism. An outer frame 30 is also provided outside the chopstick disassembly mechanism and the transmission mechanism, and a control switch 31 for opening or closing the drive assembly is provided on the outer frame 30.

[0035] The drive assembly includes a drive motor 3 and a drive shaft 4 located at the lower end of the drive motor 3. The drive shaft 4 is provided with a first transmission wheel 411, a first cam 412 and a second cam 413. The output end of the drive motor 3 is provided with a second transmission wheel 311 and a motor pulley 312 located outside the second transmission wheel 311. The first transmission wheel 411 and the second transmission wheel 311 are connected by a belt 310. The motor pulley 312 is connected to the chopstick disassembly mechanism to drive the chopstick disassembly mechanism to rotate in a circular motion. The first cam 412 is mounted on the drive shaft 4 and located outside the first transmission wheel 411. The first cam 412 drives the chopstick disassembly mechanism through a transmission mechanism. The second cam 413 is located in the control chamber 2 and drives the conveying and clamping mechanism through a push plate assembly.

[0036] like Figure 3 As shown: The transmission mechanism includes a swing arm 5. The lower end of the swing arm 5 is provided with a first guide wheel 511 that contacts the first cam 412. One end of the swing arm 5 is connected to the chopstick disassembly mechanism through a connecting mechanism. The end of the swing arm 5 away from the chopstick disassembly mechanism is provided with a first elastic element 6 that is connected to the platform 1. The lower end of the swing arm 5 is provided with a bearing fixing seat 11. A rotating shaft 12 is vertically installed in the bearing fixing seat 11 and is connected to the swing arm 5.

[0037] like Figure 3 As shown: The chopstick disassembly mechanism includes a punch fixing bracket 101 and a chuck shaft fixing bracket 102 mounted on the platform 1. A hollow chuck shaft 103 is movably mounted on the chuck shaft fixing bracket 102. A punch 104 is fixed on the punch fixing bracket 101. One end of the punch 104 away from the punch fixing bracket 101 extends into the chuck shaft 103. A chuck 105 is provided at one end of the chuck shaft 103 away from the punch fixing bracket 101. A locking hole is provided on the chuck 105 that communicates with the inside of the chuck shaft 103.

[0038] The connecting mechanism includes a retaining ring 106 on the chuck shaft 103 and a retainer 7 fixed on one side of the swing arm 5. The retaining ring 106 is set in the retainer 7 by a threaded connection. A chuck shaft pulley 8 is fixed on the chuck shaft 103 and is connected to the motor pulley 312 for transmission. Transmission bearings 9 are provided on both sides of the chuck shaft fixing frame 102. The chuck shaft 103 is located in the transmission bearings 9. The chuck shaft pulley 8 drives the chuck shaft 103 to rotate within the transmission bearings 9 by the rotation of the motor pulley 312.

[0039] In use, the handles of the combined chopsticks are clamped by a piece-by-piece conveying device. The clamp 105, fixed at one end of the clamp shaft 103, clamps the chopstick head from the end away from the handle of the combined chopsticks. Then, the clamp shaft 103 and the clamp 105 are driven to rotate by the motor pulley 312 on the drive motor 3. The clamp shaft 103 and the clamp 105 drive the chopstick head of the combined chopsticks to rotate, thereby completing the disassembly of the chopstick head and handle of the threaded combined chopsticks.

[0040] like Figure 4As shown: The concave and convex surfaces of the first guide wheel 511 and the first cam 412 at the lower end of the swing arm 5 continuously contact each other, thereby causing the clamp shaft 103 and the clamp 105 to move back and forth along the axial direction of the combined chopsticks. When the concave surface of the first guide wheel 511 and the first cam 412 contacts each other, the clamp shaft 103 is driven to the end of the chopstick head of the combined chopsticks. The clamp 105 of the clamp shaft 103 clamps the chopstick head of the combined chopsticks. Then the first guide wheel 511 will contact the convex surface of the first cam 412, causing the chopstick head of the combined chopsticks to rotate while the swing arm 5 pulls the clamp shaft 103 away from the chopsticks towards the handle of the combined chopsticks. During the pulling process, the chopstick head of the combined chopsticks will contact the punch 104 set in the clamp shaft 103. The punch 104 will push the chopstick head of the combined chopsticks outward, so that it falls directly into the collection tray 33 located at the lower end of the clamping device.

[0041] like Figure 7 As shown: The push plate assembly includes a first bearing seat 13 and a second bearing seat 14 disposed on the platform 1, and a fixed shaft 15 disposed between the first bearing seat 13 and the second bearing seat 14. A transmission rod 16 is movably disposed on the fixed shaft 15, and connecting rods 17 are provided on both sides of the transmission rod 16. A push plate 18 is fixed at the lower end of the connecting rod 17.

[0042] like Figure 6 As shown: Several one-way valves 216 are provided below the feed port 214 of the first fixed plate 211. The one-way valves 216 are located at the lower end of the push plate 18 and abut against the push plate 18.

[0043] like Figure 8 As shown: The one-way valve includes a one-way valve seat 2161 and a one-way valve lever 2162. The one-way valve lever 2162 is movably mounted on the one-way valve seat 2161 via a pin. One end of the one-way valve lever extends upward to form a blocking part 2163. When the chopsticks are pushed out by the feeding end, the end of the one-way valve lever 2162 away from the blocking part 2163 will tilt upward, while the blocking part 2163 will move downward, so that the chopsticks can pass through the blocking part 2163. When the feeding end is pulled back, the one-way valve seat 2161 at the lower end of the one-way valve lever 2162 will hold the one-way valve lever 2162 in place, preventing it from tilting upward, while the blocking part 2163 will block the chopsticks. At this time, the chopsticks located on the feeding end 17 will fall down naturally.

[0044] like Figure 7 As shown: The connecting rod 17 includes a first joint bearing 171, a second joint bearing 172, and a screw 173 connected between the first joint bearing 171 and the second joint bearing 172. The first joint bearing 171 is fixed to both sides of the transmission rod 16 by bolt connection, and the second joint bearing 172 is fixed to the push plate 18 by bolt connection.

[0045] The transmission rod 16 includes a rotating end 161 movably mounted on a fixed shaft 15, and a first rod portion 162 and a second rod portion 163 integrally formed on both sides of the rotating end 161. The first rod portion 162 and the second rod portion 163 are inclined. A second guide wheel 164 is provided between the first rod portion 162 and the second rod portion 163. The second guide wheel 164 abuts against a second cam 413. The second cam 413 controls the swing of the transmission rod 16 through the second guide wheel 164. It also includes a second elastic element 19 and a crossbar 20 fixed in the control room 2. A fixing bolt 165 is provided at the end of the first rod portion 162 and the second rod portion 163 away from the rotating end 161. The two ends of the second elastic element 19 are respectively connected to the crossbar 20 and the fixing bolt 165.

[0046] like Figure 4 As shown: The control room 2 includes a first fixed plate 211, a second fixed plate 212, and a third fixed plate 213 that surround each other. The first fixed plate 211 has a feeding port 214. The second fixed plate 212 and the third fixed plate 213 have corresponding movable grooves 215 on both sides. The push plate 18 is engaged in the movable grooves 215 on both sides and can move horizontally along the movable grooves 215. The push plate 18 has at least two feeding ends 21 on its outer side, and the feeding ends 21 are located at the lower end of the material distribution mechanism.

[0047] like Figure 5 As shown: A blocking frame 22 is fixed on the outer side of the first fixed plate 211. A fixed rubber seat 23 is fixed on the blocking frame 22 at the corresponding position of the feeding end 21. By setting the blocking frame 22 on the outer side of the control room 2 and the fixed rubber seat 23 corresponding to the feeding end 21 on the inner side of the blocking frame 22, and by setting the fixed rubber seat 23, a number of movable rubber seats 34 are set on the side of the push plate 18 near the feeding end 21. The movable rubber seats 34 and the fixed rubber seats 23 correspond one-to-one, so as to avoid damaging the chopsticks when conveying them.

[0048] like Figure 1-2 As shown: The material distribution mechanism includes a material bin 24 located at the upper end of the control room 2, a material distribution shaft 25 rotatably mounted on the control room 2, and a material distribution wheel 251 located on the material distribution shaft 25. The material distribution wheel 251 is located below the material bin 24, and a clamping plate 27 is provided between the material distribution wheel 251 and the material bin 24. The material distribution shaft 25 and the drive shaft 4 are connected by a belt 26.

[0049] The working principle of this invention is as follows: The combination chopsticks used in this embodiment include a chopstick handle and a chopstick head threadedly connected to the chopstick handle. The chopstick head is the food-grabbing end, and the material of the chopstick head is bamboo or wood. First, the combination chopsticks are neatly placed into the material bin 24, with the chopstick heads facing the chopstick disassembly mechanism. The switch of the drive motor 3 is turned on. The drive motor 3 drives the distributing rotating shaft 25 located at the lower end of the material bin 24 to rotate through the drive shaft 4, thereby causing the distributing wheel 251 to rotate. The distributing wheel 251 is provided with locking teeth. Through the locking teeth, the combination chopsticks are pushed down sequentially from the gap between the locking plate 27 and the first fixing plate 211, so that the combination chopsticks are located on the push plate 18. At this time, the second fixed plate 211 located on the drive shaft 4... Cam 413 also begins to rotate. As cam 413 rotates, its convex and flat surfaces continuously contact the second guide wheel 164 in the transmission rod 16. Since the transmission rod 16 is rotatably mounted on the shaft 15 between the first bearing seat 13 and the second bearing seat 14, the transmission rod 16 can rotate relative to the shaft 15. When the second guide wheel 164 on the transmission rod 16 contacts the convex surface of the second cam 413, the transmission rod 16 moves away from the push plate 18, thereby pulling the push plate 18. When the second guide wheel 164 on the transmission rod 16 contacts the flat surface of the second cam 413, the transmission rod 16 moves closer to the push plate 18, thereby... Pushing the push plate 18 outwards, when the push plate 18 is pulled inwards, the combined chopsticks located between the clamping plate 27 and the first fixing plate 211 fall onto the feeding end 21 at the front end of the push plate 18. Then, the push plate 18 loaded with chopsticks is pushed outwards by the pushing mechanism. When pushed, the combined chopsticks on the push plate 18 abut against the fixing rubber seat 23 to achieve the function of clamping the chopstick handles, thus completing the feeding and clamping process. At this time, the chopstick heads of the pushed-out combined chopsticks correspond to the clamps 105. By setting the first cam 412 on the drive shaft 4, the first guide wheel 511 at the lower end of the swing arm 5 and the concave and convex surfaces of the first cam 412 continuously contact each other, thereby causing the clamp shaft 103 and the clamp 105 to... The combination chopsticks move back and forth along the axial direction. When the concave surface of the first guide wheel 511 and the first cam 412 contacts, the chuck shaft 103 is driven to the end of the chopstick head. The chuck 105 of the chuck shaft 103 clamps the chopstick head. Then, the first guide wheel 511 contacts the convex surface of the first cam 412, causing the chopstick head to rotate. The swing arm 5 pulls the chuck shaft 103 away from the chopstick handle. During the pulling process, the chopstick head contacts the punch 104 set in the chuck shaft 103. The punch 104 pushes the chopstick head outward, causing it to fall directly into the collection tray 33 located at the lower end of the clamping device.
