Description

Technical Field

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

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

[0003] Currently, existing chopsticks machines typically include a feeding device, a drive mechanism, a spindle chuck, and a cutting device. The feeding device is used to transport the chopsticks to be processed into the spindle chuck, where they are automatically clamped. The spindle chuck is driven to rotate at high speed by the drive mechanism, and the chopsticks clamped by the spindle chuck are processed by the cutting device.

[0004] However, existing chopsticks machines typically use vibration to feed chopsticks to avoid clogging the feed hopper. For example, patent publication number CN112372458A discloses a mechanical polishing device for bamboo and wood chopsticks, but this feeding method generates significant vibration and noise.

[0005] Furthermore, existing chopsticks making machines typically employ a cutting device comprising a blade, a mounting base, and an XY drive module. The XY drive module is mounted on the machine frame and is connected to the mounting base. The blade is mounted on the mounting base, and the XY drive module drives the mounting base to move along the horizontal X and Y axes, allowing the blade to move along either the horizontal X or Y axis to adjust its position when cutting the chopsticks. However, this XY drive module cannot achieve precise fine-tuning of the blade, thus affecting its cutting performance.

[0006] In summary, existing chopstick making machines exhibit significant vibration and noise during the feeding process, and cannot achieve precise fine-tuning of the cutting blade, thus affecting chopstick processing. Utility Model Content

[0007] One of the objectives of this utility model is to provide a chopsticks machine that addresses the technical problems of existing chopsticks machines, such as significant vibration and noise during material feeding and the inability to precisely adjust the cutting blade, which affect chopstick processing.

[0008] To achieve the above objectives, this utility model provides a chopsticks machine, including a frame, a spindle chuck, a drive mechanism, a feeding device, and a cutting device. The spindle chuck is rotatably mounted on the frame and driven to rotate by the drive mechanism mounted on the frame. The feeding device includes a feeding hopper, a receiving plate, a pushing plate, a pushing mechanism, and a drive unit. The feeding hopper is mounted on the frame and has at least one feeding area. The receiving plate is located at the bottom of the feeding hopper. The pushing plate is slidably fitted between the receiving plate and the feeding hopper. A discharge trough is formed on the receiving plate at a position corresponding to the feeding area. The discharge trough extends along the horizontal Y-axis and can only accommodate one chopstick to be processed. A through groove is formed on the pushing plate at a position corresponding to the feeding area, connecting the discharge trough and the feeding area. The material troughs extend in the same direction. The drive unit is mounted on the frame and is used to drive the pusher plate to move back and forth along the horizontal X-axis. The pusher mechanism is mounted on the frame and is used to catch chopsticks falling from the material trough and push the caught chopsticks into the spindle chuck for clamping. The chopsticks clamped on the spindle chuck extend along the horizontal Y-axis. The cutting device includes a mounting base, a tool holder, a cutting tool, a fine-tuning mechanism, and an XY drive module. The cutting tool is mounted on the tool holder, which is mounted on the mounting base. The XY drive module is mounted on the frame and driven by the mounting base, and is used to drive the mounting base to move along the horizontal X-axis and horizontal Y-axis. The tool holder is slidably mounted on the mounting base along the horizontal X-axis. The fine-tuning mechanism is connected to the tool holder and is used to lock or fine-tune the sliding distance of the tool holder relative to the mounting base.

[0009] Furthermore, the fine-tuning mechanism includes an adjusting rod, a fixed seat, and a fixed block. The fixed seat is mounted on a mounting base and has a T-shaped groove extending along the horizontal X-axis and passing through both ends of the fixed seat. The fixed block is fixed within the T-shaped groove and has a first threaded hole along the horizontal X-axis. The tool holder is slidably connected to the T-shaped groove and has a second threaded hole coaxial with the first threaded hole. The adjusting rod has a first thread and a second thread with different pitches. The first thread is threaded to the first threaded hole, and the second thread is threaded to the second threaded hole. One end of the adjusting rod facing away from the fixed block is located outside the tool holder.

[0010] Furthermore, the fine-tuning mechanism also includes a locking component on the fixing block for locking or unlocking the tool holder from sliding relative to the T-slot.

[0011] Furthermore, the tool holder is provided with a receiving groove that extends along the horizontal Y-axis. The cutting tool is slidably connected to the receiving groove. The tool holder is also provided with a locking element for locking the cutting tool relative to the receiving groove.

[0012] Furthermore, the locking assembly includes a locking bolt and a clamping block, the clamping block being placed on the upper surface of the tool holder, the locking bolt being vertically inserted through the clamping block and threadedly connected to the fixing block, so that the clamping block can lock or unlock the tool holder from sliding relative to the T-slot.

[0013] Furthermore, the feeding mechanism includes a receiving tube and a feeding 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 feeding unit is used to push the chopsticks to be processed into the spindle chuck after they enter the receiving tube.

[0014] Furthermore, the pushing unit includes a pushing rod and a pushing power unit. The outer diameter of the pushing rod is smaller than the inner diameter of the receiving tube. The pushing power 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.

[0015] Furthermore, the drive unit 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 horizontal X-axis direction.

[0016] Furthermore, the frame is also equipped with a guide mechanism for guiding the push rod to move linearly along the horizontal Y-axis.

[0017] Furthermore, the end of the adjusting rod facing away from the fixed block is provided with a knob located outside the knife holder for rotating the adjusting rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In use, this chopsticks 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 horizontal Y-axis. At this point, multiple chopsticks are present in the feeding area, both in the through-slot and on the pusher plate. Since the discharge chute and through-slot on the support plate are both horizontal along the Y-axis, and the discharge chute can only hold one chopstick at a time, only one chopstick will fall into the discharge chute. Then, the pusher plate, driven by a drive unit, moves back and forth along the horizontal X-axis, thus pushing the chopsticks in the feeding area... One by one, the chopsticks are fed into the feeding trough to prevent them from clogging the feed hopper. The chopsticks then fall into the pushing mechanism, which pushes them into the spindle chuck along the horizontal Y-axis. Once inside the spindle chuck, the chopsticks are automatically clamped. At this point, the XY drive module drives the mounting base, which in turn moves the cutting blade on the tool holder along the horizontal X and Y axes to adjust its position for cutting the chopsticks. With the spindle chuck rotating at high speed driven by the drive mechanism, the cutting blade, guided by the XY drive module, cuts the chopsticks, achieving automated chopstick processing. Before processing the chopsticks, if fine-tuning of the cutting blade is needed, the fine-tuning mechanism can be manually unlocked. This allows for adjustments to the distance the tool holder slides relative to the mounting base along the horizontal X-axis, achieving precise blade adjustment.

[0020] In summary, the chopsticks machine of this invention achieves the dropping of chopsticks through a pushing method during the chopsticks processing process, avoiding significant vibration and noise. In addition, the fine-tuning mechanism can achieve precise fine-tuning of the cutting blade, thereby greatly improving the chopsticks processing effect. Attached Figure Description

[0039] Please refer to Figure 1 - Figure 12 This utility model provides a chopsticks making machine, including a frame 1, a spindle chuck 3, a drive mechanism 30, a feeding device 2, and a cutting device 4. The spindle chuck 3 is rotatably mounted on the frame 1, and the drive mechanism 30 is mounted on the frame 1 to drive the spindle chuck 3 to rotate. The drive mechanism 30 uses an existing drive structure, and the spindle chuck 3 uses an existing spindle chuck with an automatic clamping function to clamp the chopsticks 31 to be processed.

[0040] Reference Figure 1 and Figure 3 - Figure 6The feeding device 2 includes a feeding hopper 20, a supporting plate 23, a pushing plate 22, a pushing mechanism, and a drive unit. The feeding hopper 20 is fixed on the frame 1, and its bottom end is open. At least two partitions 201 are provided inside the feeding hopper 20. The two ends of the partitions 201 are fixedly connected to the opposite side walls inside the feeding hopper 20. The bottom surfaces of the two partitions 201 are flush with the bottom surface of the feeding hopper 20, and the two partitions 201 form a feeding area 21 inside the feeding hopper 20. Thus, the feeding hopper 20 has at least one feeding area 21. In addition, the supporting plate 23 is located at the bottom of the feeding hopper 20, and the pushing plate 22 is slidably attached between the supporting plate 23 and the feeding hopper 20. That is, the upper surface of the pushing plate 22 is slidably attached to the bottom surface of the feeding hopper 20, and the lower surface of the pushing plate 22 is slidably attached to the upper surface of the supporting plate 23. The material receiving plate 23 has a material dropping groove 230 at the position corresponding to the feeding area 21. The material dropping groove 230 extends along the horizontal Y-axis and can only accommodate one chopstick 31 to be processed. The material pushing plate 22 has a through groove 220 at the position corresponding to the feeding area 21, which connects the material dropping groove 230 and the feeding area 21. The through groove 220 extends in the same direction as the material dropping groove 230 and can accommodate multiple chopsticks 31 to be processed.

[0041] It should be noted that the feeding area 21 is formed by the two side walls of the feeding hopper 20 in the horizontal Y direction and two adjacent partitions 201, and the bottom of the feeding area 21 is supported by the pusher plate 22 and the support plate 23.

[0042] The drive unit is mounted on the frame 1 and is used to drive the pusher plate 22 to move back and forth along the horizontal X-axis direction, so as to push the chopsticks 31 to be processed in the feeding area 21 into the discharge chute 230 one by one. Specifically, refer to Figure 3 - Figure 5 The drive unit includes a drive motor 24 and a cam rocker arm 27 mechanism. The output shaft of the drive motor 24 is drivenly connected to the cam rocker arm 27 mechanism, which drives the cam rocker arm 27 mechanism to move the pusher plate 22 back and forth along the horizontal X-axis direction.

[0043] Reference Figure 3 - Figure 5The cam rocker arm 27 mechanism includes an eccentric cam 25, a pulley 26, and a rocker arm 27. The drive motor 24 is fixed on the frame 1. The output shaft of the drive motor 24 extends along the horizontal Y-axis. The eccentric cam 25 is driven and connected to the output shaft of the drive motor 24. The eccentric cam 25 is also driven and connected to the pulley 26. The pulley 26 and the eccentric cam 25 are eccentrically set with respect to the output shaft of the drive motor 24. The rocker arm 27 is fixed on the pusher plate 22. The rocker arm 27 has a waist-shaped groove 270 that extends vertically. The pulley 26 is located in the waist-shaped groove 270. The drive motor 24 drives the eccentric cam 25 to slide the pulley 26 in the waist-shaped groove 270, thereby driving the pusher plate 22 to move back and forth along the horizontal X-axis.

[0044] Reference Figure 3 and Figure 6 The pushing mechanism is mounted on the frame 1 and is used to receive chopsticks 31 falling from the discharge chute 230 and push the received chopsticks 31 into the spindle chuck 3 for clamping. Specifically, the pushing mechanism includes a receiving tube 28 and a pushing unit. The receiving tube 28 is fixed on the frame 1 and extends in the same direction as the discharge chute 230. The receiving tube 28 is located on the frame 1 and below the discharge chute 230. A receiving groove 280 is provided on the receiving tube 28. The receiving groove 280 extends in the same direction as the discharge chute 230 and is connected to it. The shape of the receiving groove 280 is the same as the shape of the discharge chute 230, so that the chopsticks 31 to be processed falling from the discharge chute 230 can enter the receiving tube 28 through the receiving groove 280. The discharge end of the receiving tube 28 is connected to the feed end of the spindle chuck 3, and the pushing unit is used to push the chopsticks 31 to be processed into the spindle chuck 3 after entering the receiving tube 28.

[0045] Reference Figure 3 and Figure 6 The feeding unit includes a feeding rod 29 and a feeding power unit 290. The outer diameter of the feeding rod 29 is smaller than the inner diameter of the receiving tube 28. One end of the feeding rod 29 is located inside the receiving tube 28, and the other end of the feeding rod 29 is driven and connected to the feeding power unit 290 mounted on the frame 1. When the chopsticks 31 to be processed in the dropping groove 230 enter the receiving tube 28 from the receiving groove 280, the feeding power unit 290 drives the feeding rod 29 to push the chopsticks 31 to be processed in the receiving tube 28 into the spindle chuck 3 along the horizontal Y-axis direction. The chopsticks 31 to be processed entering the spindle chuck 3 are automatically clamped by the spindle chuck 3.

[0046] In this embodiment, the pusher power unit 290 is a linear drive module. Of course, in other embodiments, the pusher power unit 290 can also be an electric push rod or a pneumatic push rod.

[0047] In addition, a guide mechanism 5 is provided on the frame 1 to guide the push rod 29 to move linearly along the horizontal Y-axis. Specifically, the guide mechanism 5 is a guide rod that is slidably mounted on the frame 1 along the horizontal Y-axis.

[0048] Reference Figure 2 and Figure 7 - Figure 12 The cutting device 4 includes a mounting base 40, a tool holder 41, a cutting tool 42, a fine-tuning mechanism, and an XY drive module 46. The cutting tool 42 is mounted on the tool holder 41, which is mounted on the mounting base 40. The XY drive module 46 is mounted on the frame 1 and drivenly connected to the mounting base 40, used to drive the mounting base 40 to move along the horizontal X-axis and horizontal Y-axis directions. The XY drive module 46 includes an X drive module 461 and a Y drive module 462. The X drive module 461 is mounted on the frame 1 and drivenly connected to the Y drive module 462, used to drive the Y drive module 462 to move along the horizontal X-axis direction. The Y drive module 462 is drivenly connected to the mounting base 40, used to move the mounting base 40 along the horizontal Y-axis direction.

[0049] In this embodiment, both the X-drive module 461 and the Y-drive module 462 can be linear drive modules. In other embodiments, the X-drive module 461 can be an electric push rod or a linear drive motor 24, and the Y-drive module 462 can also be an electric push rod or a linear drive motor 24.

[0050] Reference Figure 2 and Figure 7 - Figure 12The tool holder 41 is slidably mounted on the mounting base 40 along the horizontal X-axis. A fine-tuning mechanism is connected to the tool holder 41 and is used to lock or fine-tune the sliding distance of the tool holder 41 relative to the mounting base 40. Specifically, the fine-tuning mechanism includes an adjusting rod 45, a fixed base 43, a fixed block 44, and a locking assembly 47. The fixed base 43 is fixed on the mounting base 40 and has a T-slot 430 that extends along the horizontal X-axis and passes through the opposite ends of the fixed base 43. The fixed block 44 is fixed in the T-slot 430 and has a first threaded hole 440 along the horizontal X-axis. The tool holder 41 is slidably connected to the T-slot 430. The tool holder 41 is provided with a second threaded hole 411 coaxial with the first threaded hole 440. The adjusting rod 45 is provided with a first thread 450 and a second thread 451. The pitch of the first thread 450 and the second thread 451 is different. The first thread 450 is threaded to the first threaded hole 440, and the second thread 451 is threaded to the second threaded hole 411. One end of the adjusting rod 45 facing away from the fixed block 44 is located outside the tool holder 41. Therefore, the first thread 450 and the second thread 451 on the adjusting rod 45 are threadedly connected to the first threaded hole 440 and the second threaded hole 411, respectively. Since the pitches of the first thread 450 and the second thread 451 on the adjusting rod 45 are different, the first thread 450, the second thread 451, the first threaded hole 440 and the second threaded hole 411 on the adjusting rod 45 will form a differential screw drive mechanism. Since the fixed block 44 is fixed and the pitches of the first thread 450 and the second thread 451 are different, when the adjusting rod 45 is rotated, the cutting tool 42 will move slightly along the axial direction of the adjusting rod 45 with the tool holder 41, thereby achieving the precise fine-tuning effect of the cutting tool 42.

[0051] Reference Figure 9 The adjusting rod 45 has a knob 452 located outside the tool holder 41 at one end facing away from the fixing block 44. The knob 452 is used to rotate the adjusting rod 45. The knob 452 can be configured as an external hexagonal knob 452 adapted to an internal hexagonal wrench, so that the knob 452 can be driven by the internal hexagonal wrench to drive the adjustment rotation.

[0052] Of course, in other embodiments, the knob 452 can also be configured as a manual knob.

[0053] Reference Figure 8 - Figure 12A locking component 47 is disposed on a fixing block 44 for locking or unlocking the tool holder 41 from sliding relative to the T-slot 430. Specifically, the locking component 47 includes a locking bolt 471 and a clamping block 470. The clamping block 470 is placed on the upper surface of the tool holder 41. The locking bolt 471 passes vertically through the clamping block 470 and is threadedly connected to the fixing block 44, so that the clamping block 470 can lock or unlock the tool holder 41 from sliding relative to the T-slot 430. When it is necessary to fine-tune the cutting tool 42, the locking bolt 471 is loosened, which unlocks the clamping block 470 and locks the tool holder 41. When the cutting tool 42 is cutting the chopsticks 31, the locking bolt 471 is tightened, so that the clamping block 470 locks the tool holder 41, thereby locking the tool holder 41 from sliding relative to the T-slot 430.

[0054] Reference Figure 8 - Figure 12 The tool holder 41 has a receiving groove 410 extending along the horizontal Y-axis. The cutting tool 42 is slidably connected to the receiving groove 410. The tool holder 41 also has a locking member 48 for locking the cutting tool 42 relative to the receiving groove 410. Specifically, the tool holder 41 has a third threaded hole (not shown) extending along the horizontal X-axis and communicating with the receiving groove 410. The locking member 48 is threadedly connected to the third threaded hole. Thus, by tightening the locking member 48, the cutting tool 42 can be locked to slide relative to the receiving groove 410. When it is necessary to replace a different cutting tool 42, simply loosen the locking member 48. In addition, a fourth threaded hole (not shown) is provided on the tool holder 41. The fourth threaded hole extends vertically and passes through the receiving groove 410. The fourth threaded hole is also threadedly connected to a locking member 48, which can further lock the cutting tool 42 to slide relative to the receiving groove 410. It can be seen that the solution of locking the cutting tool 42 relative to the receiving groove 410 by locking the cutting tool 42 to slide can replace cutting tools 42 of different specifications.

[0055] Based on the above structure, referring to Figure 2 A collecting plate 6 is also fixed on the frame, located below the spindle chuck, so that the debris generated after the cutting tool 42 processes the chopsticks falls onto the collecting plate 6. Furthermore, the collecting plate 6 has multiple through holes 60 penetrating its opposite surfaces. The through holes 60 have an oblong groove structure. A negative pressure suction conveying system (not shown) is connected to the lower surface of the collecting plate 6. This system uses negative pressure to remove waste from the collecting plate, achieving the effect of collecting waste and preventing its accumulation. The negative pressure suction conveying system is a conventional one, which will not be described in detail here.

[0056] The working principle of this chopsticks machine:

[0057] In use, multiple chopsticks 31 to be processed are placed in the feeding area 21 and supported by the supporting plate 23 and the pushing plate 22, so that the chopsticks 31 to be processed in the feeding area 21 extend along the horizontal Y-axis direction. At this time, there are multiple chopsticks 31 to be processed in the feeding area 21, in the through groove 220 and on the pushing plate 22. Since the dropping groove 230 on the supporting plate 23 and the through groove 220 are both in the horizontal Y-axis direction, and the dropping groove 230 can only accommodate one chopstick 31 to be processed, only one chopstick 31 to be processed falls into the dropping groove 230 among the multiple chopsticks 31 to be processed in the feeding area 21. At this time, the pushing plate 22 is driven by the drive unit to move back and forth along the horizontal X-axis direction, which can push the chopsticks 31 to be processed in the feeding area 21. The chopsticks 31 to be processed are fed one by one into the feeding trough 230 to prevent them from blocking the feeding hopper 20. The chopsticks 31 in the feeding trough 230 fall into the pushing mechanism and are pushed into the spindle chuck 3 along the horizontal Y-axis. The chopsticks 31 in the spindle chuck 3 are automatically clamped by the spindle chuck 3. At this time, the XY drive module 46 drives the mounting base 40 to move the cutting blade 42 on the tool holder 41 along the horizontal X-axis and horizontal Y-axis to adjust the position of the cutting blade 42 to cut the chopsticks 31. At this time, with the drive mechanism 30 driving the spindle chuck 3 to rotate at high speed, the cutting blade 42 can be moved by the XY drive module 46 to cut the chopsticks 31, realizing the automated processing of chopsticks 31.

[0058] In summary, the chopsticks machine of this utility model achieves the dropping of chopsticks 31 by pushing the material during the processing of chopsticks 31, thus avoiding large vibrations and noises; in addition, the fine-tuning mechanism can achieve precise fine-tuning of the cutting blade 42, thereby greatly improving the processing effect of chopsticks 31.

[0059] 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.
