Description

Technical Field

[0001] This utility model relates to the field of chopsticks machine technology, and in particular to a feeding device for a chopsticks machine. Background Technology

[0002] A chopsticks machine is a mechanical device used to process chopsticks.

[0003] Currently, the feeding devices of existing chopstick machines are prone to clogging the feed hopper during feeding, affecting the efficiency of chopstick processing. To address this, existing patent publication number CN112372458A discloses a mechanical polishing device for bamboo and wood chopsticks, which uses vibration to discharge chopsticks, preventing clogging of the feed hopper. However, the vibration method used in chopstick machines to discharge chopsticks generates significant vibration and noise. Utility Model Content

[0004] One of the purposes of this utility model is to provide a feeding device for a chopsticks machine, which aims to solve the technical problem that existing chopsticks machines use vibration to feed chopsticks, resulting in significant vibration and noise.

[0005] To achieve the above objectives, this utility model provides a feeding device for a chopsticks machine, including a frame and a feeding hopper. The feeding hopper is mounted on the frame, with an open bottom. At least two partitions are provided inside the feeding hopper, with the bottom surfaces of the two partitions flush with the end face of the open end. The two partitions create a feeding zone within the feeding hopper, where chopsticks to be processed extend along the width of the feeding hopper. The frame also includes a drive mechanism and a pusher plate. The pusher plate slides against the end face of the open end, and a feeding device is attached to the bottom surface of the pusher plate. A material support plate is fixed on the frame. A material discharge groove is formed on the material support plate at the position corresponding to the feeding area, extending through its opposite surface. The material discharge groove extends along the width direction of the feeding hopper and can only accommodate one chopstick to be processed. A through groove is formed on the pusher plate at the position corresponding to the feeding area, connecting the material discharge groove and the feeding area. The through groove extends in the same direction as the material discharge groove and is used to accommodate multiple chopsticks to be processed. The drive mechanism is used to drive the pusher plate to move back and forth along the length direction of the feeding hopper.

[0006] Furthermore, the frame is also equipped with a pushing mechanism, which is used to catch chopsticks falling from the discharge chute and push the caught chopsticks out.

[0007] Furthermore, the pushing mechanism includes a receiving tube and a pushing unit. The receiving tube extends in the same direction as the discharge chute. The receiving tube is mounted on the frame and located below the discharge chute. A receiving groove is provided on the receiving tube. The receiving groove extends in the same direction as the discharge chute and is connected to it. The pushing unit is used to push out the chopsticks to be processed that have entered the receiving tube.

[0008] Furthermore, the pushing unit includes a pushing rod and a driving unit. The outer diameter of the pushing rod is smaller than the inner diameter of the receiving tube. The driving unit is drivenly connected to the pushing rod and is used to drive the pushing rod to push along the axial direction of the receiving tube.

[0009] Furthermore, the driving mechanism includes a drive motor and a cam rocker arm mechanism. The drive motor is mounted on the frame, and the output shaft of the drive motor is drivenly connected to the cam rocker arm mechanism to drive the cam rocker arm mechanism to move the pusher plate back and forth along the length direction of the feed hopper.

[0010] Furthermore, the cam rocker arm mechanism includes an eccentric cam, a pulley, and a rocker arm. The output shaft of the drive motor extends along the width direction of the feed hopper. The eccentric cam is driven and connected to the output shaft of the drive motor. The eccentric cam is also driven and connected to the pulley. The pulley is eccentrically positioned relative to the output shaft of the drive motor. The rocker arm is fixed to the pusher plate. The rocker arm has a waist-shaped groove that extends vertically. The pulley is located within the waist-shaped groove. The drive motor drives the eccentric cam to slide the pulley within the waist-shaped groove, thereby causing the pusher plate to move back and forth along the length direction of the feed hopper.

[0011] Furthermore, one end of the push rod is located inside the receiving tube, and the other end of the push rod is connected to a connecting plate disposed on the frame and located outside the receiving tube. The drive unit is connected to the connecting plate.

[0012] Furthermore, the frame is also equipped with a guide mechanism for guiding the push rod to move linearly along the width direction of the feed hopper.

[0013] Furthermore, the feeding hopper is provided with multiple feeding areas, and multiple material discharge troughs, material receiving pipes and through troughs are also provided. Each material discharge trough corresponds to each feeding area, each through trough corresponds to each material discharge trough, and each material receiving pipe corresponds to each material discharge trough.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In use, the feeding device of this chopstick machine places multiple chopsticks to be processed into the feeding area, supported by a support plate and a pusher plate. The chopsticks extend along the width of the feeding hopper. At this time, there are multiple chopsticks to be processed in the feeding area, in the trough, and on the pusher plate. Because the bottom surfaces of the two partitions are flush with the bottom surface of the feeding hopper, and the bottom surface of the feeding hopper is in contact with the pusher plate, and the support plate is in contact with the lower surface of the pusher plate, the chopsticks to be processed in the feeding area... The chopsticks will not enter the gap between the partition and the pusher plate; and since the discharge groove on the receiving plate extends along the width of the feeding hopper and can only accommodate one chopstick at a time, only one chopstick will fall into the discharge groove among the multiple chopsticks to be processed in the feeding area. Based on this, by driving the pusher plate back and forth along the length of the feeding hopper through the drive mechanism, the chopsticks to be processed in the feeding area can be pushed into the discharge groove one by one, avoiding the chopsticks from blocking the feeding hopper. In summary, the feeding device of this chopstick machine realizes the discharge of chopsticks by pushing, avoiding the generation of large vibrations and noise. Attached Figure Description

[0028] Please refer to Figure 1 - Figure 6This utility model provides a feeding device for a chopsticks machine, including a frame 1, a feeding hopper 2, a drive mechanism, a pusher plate 3, and a receiving plate 4. The feeding hopper 2 is fixed on the frame 1, and its bottom end is open. At least two partitions 20 are provided inside the feeding hopper 2, and the two ends of the partitions 20 are fixedly connected to the opposite side walls inside the feeding hopper 2. The bottom surfaces of the two partitions 20 are flush with the bottom surface of the feeding hopper 2, and the two partitions 20 form a feeding area 21 inside the feeding hopper 2. The chopsticks to be processed located in the feeding area 21 extend along the width direction of the feeding hopper 2. The pusher plate 3 slides against the bottom surface of the feed hopper 2. The support plate 4 is fixed on the frame 1 and is against the bottom surface of the pusher plate 3. A discharge trough 40 is provided on the support plate 4 at the position corresponding to the feed area 21. The discharge trough 40 penetrates the upper and lower surfaces of the support plate 4 and extends along the width direction of the feed hopper 2. The discharge trough 40 can only accommodate one chopstick to be processed. A through groove 30 is provided on the pusher plate 3 at the position corresponding to the feed area 21. The through groove 30 connects the discharge trough 40 and the feed area 21. The extension direction of the through groove 30 is the same as the extension direction of the discharge trough 40. The through groove 30 can accommodate multiple chopsticks to be processed. The drive mechanism is set on the frame 1 and is used to drive the pusher plate 3 to move back and forth along the length direction of the feed hopper 2 to push the chopsticks to be processed in the feed area 21 into the discharge trough 40 one by one.

[0029] It should be noted that, referring to Figure 1 The feeding area 21 is formed by the two side walls in the width direction of the feeding hopper 2 and two adjacent partitions 20, and the bottom of the feeding area 21 is supported by the pusher plate 3 and the support plate 4.

[0030] In use, the feeding device of this chopstick machine places multiple chopsticks to be processed into the feeding area 21, which is supported by the supporting plate 4 and the pushing plate 3. The chopsticks in the feeding area 21 extend along the width of the feeding hopper 2. At this time, there are multiple chopsticks to be processed in the feeding area 21, in the through groove 30, and on the pushing plate 3. Because the bottom surfaces of the two partitions 20 are flush with the bottom surface of the feeding hopper 2, and the bottom surface of the feeding hopper 2 is in contact with the pushing plate 3, and the supporting plate 4 is in contact with the lower surface of the pushing plate 3, the chopsticks to be processed in the feeding area 21 will not enter the gap between the partitions 20 and the pushing plate 3. It will not enter the gap between the receiving plate 4 and the pusher plate 3; since the material drop groove 40 on the receiving plate 4 extends along the width direction of the feeding hopper 2, and the material drop groove 40 can only accommodate one chopstick to be processed, when the material drop groove 40 is connected to the through groove 30, only one chopstick to be processed among the multiple chopsticks to be processed in the feeding area 21 will fall into the material drop groove 40; based on this, by driving the pusher plate 3 to move back and forth along the length direction of the feeding hopper 2 through the drive mechanism, the chopsticks to be processed in the feeding area 21 can be pushed into the material drop groove 40 one by one, avoiding the chopsticks to be processed from blocking the feeding hopper 2.

[0031] In summary, the feeding device of this chopstick machine achieves the dropping of chopsticks by pushing the material. Compared with the existing method of dropping chopsticks by vibration, the feeding device of this chopstick machine can avoid generating greater vibration and noise.

[0032] Based on the above structure, a pushing mechanism is also provided on the frame 1. The pushing mechanism is used to receive chopsticks falling from the discharge chute 40 and push the received chopsticks out, thereby pushing the chopsticks to be processed into the clamping head 9 on the chopstick machine. Specifically, the pushing mechanism includes a receiving tube 7 and a pushing unit. The receiving tube 7 extends in the same direction as the discharge chute 40 and is fixed on the frame 1, located below the discharge chute 40. The receiving tube 7 has a receiving groove 70, which extends in the same direction as the discharge chute 40 and is correspondingly connected. The shape of the receiving groove 70 is the same as the shape of the discharge chute 40, so that the chopsticks to be processed falling from the discharge chute 40 can enter the receiving tube 7 through the receiving groove 70. The pushing unit is used to push out the chopsticks to be processed that have entered the receiving tube 7. That is, after the chopsticks to be processed fall out of the dropping groove 40 and enter the receiving tube 7 through the receiving groove 70, they are pushed out by the pushing unit.

[0033] In one embodiment, the pushing unit includes a pushing rod 6 and a driving unit 60. The outer diameter of the pushing rod 6 is smaller than the inner diameter of the receiving tube 7, allowing the pushing rod 6 to enter the receiving tube 7. The driving unit 60 is fixed on the frame 1 and is a linear drive module. The driving unit 60 is driven by the pushing rod 6 to push the pushing rod 6 axially along the receiving tube 7, thereby pushing out the chopsticks to be processed inside the receiving tube 7. Further, one end of the pushing rod 6 is located inside the receiving tube 7, and the other end is connected to a connecting plate 8 disposed on the frame 1 and located outside the receiving tube 7. The driving unit 60 is connected to the connecting plate 8. Thus, by driving the connecting plate 8 through the driving unit 60, the pushing rod 6 moves axially along the receiving tube 7, thereby pushing out the chopsticks to be processed inside the receiving tube 7.

[0034] In other embodiments, the drive unit 60 may also be an electric actuator or a pneumatic actuator.

[0035] In one embodiment, in order to enable the push rod 6 to move stably in a straight line along the width direction of the feed hopper 2, a guide mechanism 61 is also provided on the frame 1 to guide the push rod 6 to move in a straight line along the width direction of the feed hopper 2. Specifically, the guide mechanism can be a guide rail structure or a guide rod that is slidably arranged on the frame 1 along the width direction of the feed hopper 2, and is not limited here.

[0036] In one embodiment, the driving mechanism includes a drive motor 5 and a cam rocker arm mechanism. The drive motor 5 is fixed on the frame 1, and the output shaft of the drive motor 5 is driven and connected to the cam rocker arm mechanism to drive the cam rocker arm mechanism to move the pusher plate 3 back and forth along the length direction of the feed hopper 2. Specifically, the cam rocker arm mechanism includes an eccentric cam 50, a pulley 51, and a rocker arm 52. The output shaft of the drive motor 5 extends along the width direction of the feed hopper 2. The eccentric cam 50 is driven and connected to the output shaft of the drive motor 5. The eccentric cam 50 is also driven and connected to the pulley 51. The pulley 51 is eccentrically positioned with respect to the output shaft of the drive motor 5. The rocker arm 52 is fixed on the pusher plate 3. The rocker arm 52 has a waist-shaped groove 53 that extends vertically. The pulley is located in the waist-shaped groove 53. The drive motor 5 drives the eccentric cam 50 to slide the pulley 51 in the waist-shaped groove 53, thereby driving the pusher plate 3 to move back and forth along the length direction of the feed hopper 2.

[0037] Of course, in other embodiments, the drive mechanism may also be a linear drive module or other similar structure.

[0038] To improve the feeding efficiency, the feeding hopper 2 is equipped with multiple feeding zones 21 as described above, as well as multiple material discharge troughs 40, material receiving pipes 7, and through troughs 30. Each material discharge trough 40 corresponds to one of the feeding zones 21, and each through trough 30 corresponds to one of the material discharge troughs 40. Each material receiving pipe 7 corresponds to one of the material discharge troughs 40. The chopstick machine also has multiple chopstick grippers 9, which are existing automatic grippers. Each gripper corresponds to one of the material receiving pipes 7, and the discharge end of the material receiving pipe 7 is connected to the feed end of each gripper. Multiple push rods 6 are also provided, each corresponding to one of the material receiving pipes 7. Therefore, chopsticks to be processed can be placed in each feeding area 21. Under the action of the drive mechanism driving the pusher plate 3 to move back and forth along the length of the feeding hopper 2, the chopsticks to be processed in each feeding area 21 enter each receiving tube 7 through each dropping groove 40. Finally, the drive unit 60 drives each pusher rod 6 to push the chopsticks to be processed in each receiving tube 7 into each clamp, which is automatically clamped by the clamp 9, thereby greatly improving the feeding effect of the feeding device of the chopstick machine of this utility model.

[0039] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
