Description

Technical Field

[0001] This invention relates to the field of chopstick processing equipment technology, and in particular to an automatic chopstick raw material slicing machine. Background Technology

[0002] With the global spread of Chinese culinary culture, the demand for chopsticks is increasing daily. Simultaneously, continuous advancements in production technology have driven chopstick production equipment towards automation and high efficiency, becoming a significant trend in the industry. However, the production of chopsticks in China, especially traditional chopsticks with different ends, still largely relies on manual labor. The production process for chopsticks with different ends mainly includes splitting, branching, planing, and polishing to remove sharp edges. In the splitting process, the raw wood material needs to be cut into pieces that are wider at one end and narrower at the other. Typically, workers place the side of the wood against a beveled baffle and push it towards the saw blade, cutting out pieces that are wider at one end and narrower at the other. The wood is then flipped over, and the same side is placed against the beveled baffle again to cut another piece with different ends. This process of flipping and cutting is repeated continuously, resulting in high labor intensity, low efficiency, difficulty in ensuring consistent size for each piece, and a high risk of hand cuts.

[0003] To improve production efficiency, some automated equipment has been developed. For example, Chinese patent CN203792458U discloses an automatic chopstick production machine, which includes a frame composed of multiple machine bodies. Each machine body consists of a feeding system, a conveying system, a sawing mechanism, and a discharging system. It adopts a fully automated structure, processing chopsticks into finished products through the feeding system, conveying system, sawing mechanism, and discharging system. The conveying system can be equipped with multiple pressing mechanisms. The machine can process multiple chopsticks simultaneously in one operation, resulting in extremely high efficiency and requiring no human intervention. However, this automatic chopstick production machine still cannot automatically cut the blanks into wide and narrow sections, and the cut finished products fall directly into the hopper, resulting in a messy and disorganized product that still requires manual reorganization. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned problems and provide an automatic chopstick raw material slicing machine that can not only automatically cut chopsticks into slices of different widths, but also automatically output and stack the slices.

[0005] The technical solution of this invention is: An automatic slitting machine for chopstick raw materials, characterized in that it comprises: The machine platform is used to support the various components of the automatic chopstick raw material slicing machine. A coordinate system is defined on it, where the X direction is defined as the cutting feed direction, the Y direction is the horizontal direction perpendicular to the X direction, and the Z direction is the vertical direction perpendicular to the XY plane. A material platform is used to support the sheet material to be sliced ​​on the XY plane. A cutting device for cutting sheet metal along the X-direction, comprising a saw blade and a first drive motor for rotating the saw blade, wherein the saw blade is arranged perpendicular to the Y-direction and its cutting plane coincides with the XZ plane; The feeding device is used to drive the relative movement between the table and the saw blade in the X direction to achieve cutting; The feeding system is used to prepare materials and push the sheets to the material table, including the material preparation bin and the pushing component; The feeding system is used to output and stack the cut sheet materials; The control module is connected to the cutting device, feeding device, feeding system, and discharging system respectively, and is used to control the operation of the cutting device, feeding device, feeding system, and discharging system according to preset programs and parameters; The material platform is equipped with a width positioning device and a top-loading device, located on both sides of the sheet material to be sliced ​​in the Y direction. The width positioning device consists of two sets, each including a first lead screw motor. The two first lead screw motors are located on the sides of both ends of the sheet material's X-direction length, with their lead screw shafts arranged along the Y-direction. The ends of the two lead screw shafts respectively define the Y-direction positions of both ends of the sheet material to be sliced ​​in the X-direction, thereby defining the width of the sliced ​​sheet material at both ends in the X-direction. The top-loading device includes a top-loading actuator for pushing the sheet material to be sliced ​​along the Y-direction to at least indirectly abut against the lead screw shaft. The control module is electrically connected to the first lead screw motors and the top-loading actuator, and the control module includes a control unit for controlling the alternating extension and retraction of the two lead screw shafts to alternately cut slices with opposite width and narrow ends. The feeding system includes a stacking platform, a clamping device, a feeding guide rail, and a feeding drive device. The feeding guide rail is fixedly arranged along the X-direction. The stacking platform is fixedly installed on the machine base, located on one side of the feeding guide rail in the Y-direction. The stacking platform has at least two stacking positions. The clamping device is used to clamp and release the cut sheet material. The clamping device is slidably arranged on the feeding guide rail and is driven by the feeding drive device to reciprocate along the feeding guide rail to transport the sheet material to the stacking platform. The control module is electrically connected to the feeding drive device and the clamping device, and the control module is equipped with a control unit for controlling the stacking position of the sheet material to realize the classification and stacking of sheet material with different width and narrow end directions.

[0006] The control module controls the lead screw shafts of two first lead screw motors to extend and retract alternately based on preset parameters. In conjunction with the feeding device, the positions of the two ends of the sheet material to be sliced ​​in the X direction are effectively limited in the Y direction, thus enabling the alternating cutting of sheets with opposite width and narrow ends. The control module also controls the discharge drive device and clamping device based on preset parameters to alternately transport the sheets to two stacking positions on the stacking platform, achieving the classification and stacking of sheets with different width and narrow ends. The entire process from feeding, cutting, sheet picking to stacking is digitally controlled and automated, greatly improving production efficiency, reducing labor intensity and labor costs. Moreover, the precise control of the lead screw motors ensures that the size of each sheet is consistent, improving product quality and consistency.

[0007] Furthermore, in the aforementioned automatic chopstick raw material slicing machine, each set of width positioning devices also includes a positioning rod. The positioning rod is slidably arranged on the material platform along the Y direction and is located between the lead screw shaft of the first lead screw motor and the material to be sliced. After the top material actuator pushes, the two ends of the positioning rod abut against the lead screw shaft of the first lead screw motor and the side of the material to be sliced, respectively.

[0008] Furthermore, in the aforementioned automatic chopstick raw material slicing machine, the feeding device includes two feeding actuators installed parallel to each other on the material platform along the Y direction. The output ends of the two feeding actuators are respectively aligned with the sides of the two ends of the X-direction length of the material to be sliced. The action of the two feeding actuators can push the material to be sliced ​​along the Y direction to at least indirectly abut against the lead screw shaft.

[0009] As an optimization, in the aforementioned automatic chopstick raw material slicing machine, the material platform is further equipped with two sets of pressing devices. Each pressing device includes at least one pressing actuator fixedly installed on the material platform and a pressing plate connected to the output end of the pressing actuator. The pressing actuator drives the pressing plate to move downward along the Z-axis to vertically press the material onto the material platform. The pressing plates of the two sets of pressing devices are respectively located on both sides of the cutting path. Having two sets of pressing devices allows for the separate pressing of the material on both sides of the cutting path during the cutting process, thereby improving the stability of the cutting process.

[0010] As an optimization, in the aforementioned automatic chopstick raw material slicing machine, the feeding direction of the feeding system is X-axis. The material platform is also equipped with a length positioning device for adjusting the X-axis feeding position of the material according to its X-axis length. The length positioning device includes a positioning baffle and at least one second lead screw motor. The positioning baffle is perpendicular to the X-axis and located at the end of the predetermined feeding stroke of the material on the material platform. The second lead screw motor is connected to the positioning baffle and drives it to move along the X-axis to adjust the final feeding position of the material. This length positioning device can automatically adjust the feeding position according to the X-axis length of different materials, and the use of a lead screw motor drive achieves precise positioning, ensuring that each piece of material can be accurately placed at the cutting position, thereby improving the accuracy and consistency of slicing.

[0011] Furthermore, in the aforementioned automatic chopstick raw material slitting machine, the material preparation bin is fixedly installed on one side of the machine platform in the X direction, for horizontally stacking sheet materials. The bottom surface of the material preparation bin is flush with the upper surface of the platform. The bottom of the material preparation bin is provided with a feeding channel that allows only one sheet material to pass through in the X direction. The pushing assembly includes a pushing plate, a pushing guide rail, and a pushing actuator. The pushing guide rail is fixedly installed on the machine platform in the X direction. The pushing plate is slidably installed on the pushing guide rail. The pushing surface of the pushing plate is opposite to the X-direction end face of the bottom sheet material in the material preparation bin. The pushing actuator is connected to the pushing plate and is used to drive the pushing plate to move along the pushing guide rail, thereby pushing the bottom sheet material in the material preparation bin to move in the X direction and feed it onto the platform.

[0012] Furthermore, in the aforementioned automatic chopstick raw material slicing machine, the material table is configured to move along the X-direction by being driven by a feeding device, and the saw blade is fixedly installed on the movement path of the material table. The feeding device includes a feeding guide rail and a feeding actuator. The feeding guide rail is fixedly installed on the machine platform along the X-direction, and the material table is slidably installed on the feeding guide rail. The feeding actuator is connected to the material table and is used to drive the material table to reciprocate along the feeding guide rail. The initial position of the material table is located on the feeding path of the sheet material.

[0013] As an optimization, in the aforementioned automatic chopstick raw material slicing machine, the material table consists of a first side material table, a middle material table, and a second side material table arranged in parallel along the Y direction. The middle material table is located on the feeding path of the board material, and a cutting gap is left between the middle material table and the first side material table for the saw blade to pass through. The feeding device includes at least two feed guide rails parallel to both sides of the machine table surface. The first and second side material tables are slidably mounted on the feed guide rails on both sides, respectively. The middle material table is configured to be fixed to the first and second side material tables in the X direction, and can be driven by a retraction actuator to reciprocate between the first and second side material tables in the Y direction. During the return process of the material table after cutting, the retraction actuator drives the middle material table away from the first side material table, which can avoid the high-speed rotating saw blade during the return trip, thereby avoiding contact between the saw blade and the material table or the remaining board material.

[0014] As an optimization, in the aforementioned automatic chopstick raw material slicing machine, the clamping device includes a base, a clamping assembly, and a lifting module. The base is slidably mounted on the discharge guide rail and connected to the discharge drive device. The clamping assembly includes a clamping head for Y-axis clamping and a clamping actuator for driving the clamping head to clamp. The lifting module is used to drive the clamping assembly to rise and fall along the Z-axis. The lifting module includes a lifting plate movably connected above the base and a lifting actuator for driving the lifting plate to rise and fall along the Z-axis. The clamping assembly is at least indirectly mounted on the lifting plate. The lifting module allows the clamping assembly to rise and then return to its initial position, thereby avoiding collisions with the chopsticks already stacked on the stacking platform during the return stroke, preventing damage or displacement.

[0015] As an optimization, in the aforementioned automatic chopstick raw material slicing machine, the discharging system further includes at least one set of material sorting devices. Each set of material sorting devices includes a material sorting plate and a material sorting actuator. A square hole is provided on the stacking platform. The material sorting plate is arranged perpendicular to the Y-axis in the square hole. The material sorting actuator is fixedly installed below the stacking platform and connected to the material sorting plate. It is used to drive the material sorting plate away from the discharging guide rail along the Y-axis, thereby pushing the outermost sheet material on the stacking platform in the X-axis inward to squeeze and align the inner sheet material. The material sorting device can automatically push the sheet material to the inside of the stacking platform, which not only makes room for the next sheet material but also ensures that the sheet material is neatly arranged for subsequent operations without the need for manual sorting.

[0016] The beneficial effects of this invention are: 1. By controlling the operation of the feeding system, feeding device, cutting device and discharging system according to the preset program and parameters through the control module, the entire process of feeding, cutting, picking up and stacking is digitally and precisely controlled and automated, thereby greatly improving production efficiency and product quality, and reducing labor intensity and labor costs. 2. By controlling the lead screw shafts of the two first lead screw motors to extend and retract alternately based on preset parameters through the control module, and in conjunction with the action of the top material device, it can automatically cut sheet materials with opposite width and narrow ends, eliminating the need for manual flipping of the sheet material. This not only reduces labor intensity and improves production efficiency, but also improves product quality and consistency through precise control of the lead screw motors. 3. The discharge system can automatically classify and stack sheet materials with different width and narrow ends, and align and organize them through the material sorting device to facilitate subsequent operations without manual intervention.

[0030] like Figure 1As shown, the automatic chopstick raw material slicing machine provided in this embodiment includes a machine base 10, a feeding system, a material table, a feeding device, a cutting device, a discharging system, and a control module mounted on the machine base 10. The control module is communicatively connected to the feeding system, the feeding device, the cutting device, and the discharging system, and is used to control the operation of the feeding system, the feeding device, the cutting device, and the discharging system according to preset programs and parameters. To help to more clearly describe the structure and movement direction of each component, a coordinate system is first defined on the machine base 10, where the X-axis is defined as the cutting and feeding direction, the Y-axis is the horizontal direction perpendicular to the X-axis, and the Z-axis is the vertical direction perpendicular to the XY plane.

[0031] like Figure 3 and Figure 4As shown, the feed table is used to support the sheet metal 11 to be sliced ​​on the XY plane. The cutting device is used to cut the sheet metal 11 on the feed table along the X direction. The cutting device includes a saw blade 21 and a first drive motor 22 that drives the saw blade 21 to rotate. The feeding device is used to drive the feed table and the saw blade 21 to move relative to each other in the X direction to achieve cutting. In this embodiment, the feed table is configured to be driven by the feeding device to move along the X direction. The saw blade 21 is fixedly installed on the movement path of the feed table. The saw blade 21 is set perpendicular to the Y direction, and its cutting plane coincides with the XZ plane. Specifically, the feeding device includes a feed guide rail 31 and a feed actuator 32. The feed guide rail 31 is fixedly installed on the table surface of the machine tool 10 along the X direction. The feed table is slidably installed on the feed guide rail 31. The feed actuator 32 is connected to the feed table and is used to drive the feed table to reciprocate along the feed guide rail 31. The initial position of the feed table is located on the feeding path of the sheet metal 11. The feeding device also includes stroke sensing switches 33 located at both ends of the feeding guide rail 31, used to sense the position of the material table and control the action of the feeding actuator 32. In this embodiment, the feeding actuator 32 is a hydraulic cylinder, fixedly mounted on the machine base 10, located at one end of the feeding guide rail 31 in the X direction, and the piston rod of the feeding actuator 32 is connected to the material table. The cutting device also includes a cutting seat 23 and a rotating shaft 24 rotatably supported on the cutting seat 23. The cutting seat 23 is fixed to the machine base 10, and the rotating shaft 24 is arranged along the Y direction. One end of the shaft is fixedly mounted with the saw blade 21, and the other end is connected to the output shaft of the first drive motor 22 through a pulley transmission mechanism. The first drive motor 22 is fixedly mounted below the machine base 10. In order to collect and remove the wood chips and dust generated during the cutting process in a timely manner and improve the production environment, the cutting device is also equipped with a chip removal assembly. The chip removal assembly includes a chip collection box 25 that partially surrounds the saw blade 21, a dust collection pipe 26 communicating with the chip collection box 25, and a negative pressure dust collection device (not shown in the figure) connected to the dust collection pipe 26. In addition, in order to collect the waste generated during the cutting process, a waste outlet 27 is provided on the machine 10. The waste outlet 27 is located after the saw blade 21 along the cutting direction. An inclined hopper 28 is provided below the waste outlet 27. Workers can place a collection basket at the outlet of the hopper 28. The waste falls from the waste outlet 27 and slides into the collection basket through the hopper 28.

[0032] like Figure 6As shown, the feed platform consists of a first side feed platform 41, a middle feed platform 42, and a second side feed platform 43 arranged in parallel along the Y direction. The middle feed platform 42 is located on the feeding path of the sheet 11 and is used to carry the sheet 11 to be sliced. The first side feed platform 41 and the second side feed platform 43 are respectively located on both sides of the first side feed platform 41 in the Y direction. The upper surfaces of the three feed platforms are coplanar. A cutting gap 44 is left between the middle feed platform 42 and the first side feed platform 41 for the saw blade 21 to pass through. The feeding device has at least two feed guide rails 31 arranged parallel to each other on both sides of the table surface of the machine 10 along the X direction. The first and second side feed platforms 41 and 43 are slidably mounted on the feed guide rails 31 on both sides by sliders. The middle feed platform 42 is set to be fixed to the first and second side feed platforms 41 and 43 in the X direction, and can be driven by the retraction actuator 45 to reciprocate between the first and second side feed platforms 41 and 43 in the Y direction. In this embodiment, to ensure the stability of the material platform during operation, two feed guide rails 31 are provided on one side corresponding to the first side material platform 41, thus there are a total of three feed guide rails 31. In this embodiment, the retraction actuator 45 is a cylinder, which is fixedly installed on the second side material platform 43 along the Y direction. A connecting plate 46 is fixedly installed on the table surface of the intermediate material platform 42. The piston rod of the retraction actuator 45 is connected to the connecting plate 46. The installation positions of the retraction actuator 45 and the connecting plate 46 are not limited to this and can be interchanged. In order to support the intermediate material platform 42 and guide it during its movement, a guide connection structure 47 is provided between the intermediate material platform 42 and the first side material platform 41 and the second side material platform 43. The guide connection structure 47 between two adjacent material platforms includes two sets of guide rails and sliders. The guide rails are fixed to one of the material platforms and are arranged along the Y direction. The sliders are fixed to the other material platform and are slidably connected to the guide rails. The initial position of the intermediate material table 42 is close to the first side material table 41 during the cutting process. During the return process of the material table, the retraction actuator 45 drives the intermediate material table 42 away from the first side material table 41 to avoid the high-speed rotating saw blade 21 during the return.

[0033] The feeding system is used to prepare materials and push the sheet metal 11 to the intermediate material station 42, such as Figure 5As shown, the feeding direction of the automatic chopstick raw material slicing machine in this embodiment is X-axis. The feeding system includes a material preparation bin 51 and a pushing component. The material preparation bin 51 is fixedly installed on the machine base 10, located on the side of the material platform opposite to the cutting direction in the X-axis direction. It is used to horizontally stack the sheet material 11. The material preparation bin 51 consists of a base plate 511 and four baffles 512 perpendicular to the XY plane. The worker feeds the material from the top. One baffle 512 in the X-axis and one in the Y-axis are adjustable to accommodate sheet material 11 of different sizes. The bottom surface of the material preparation bin 51 (i.e., the upper surface of the base plate 511) is flush with the upper surface of the material platform to facilitate feeding. The bottom of the material preparation bin 51 (i.e., between the base plate 511 and the four baffles 512) is provided with a feeding channel that allows only one sheet material 11 to pass through in the X-axis direction. The feeding assembly includes a feeding plate 52, a feeding guide rail 53, and a feeding actuator 54. The feeding guide rail 53 is fixedly mounted on the machine base 10 along the X direction. The feeding plate 52 is slidably mounted on the feeding guide rail 53 via a slider. The pushing surface of the feeding plate 52 is opposite to the X-direction end face of the bottom sheet material 11 in the material preparation bin 51. The feeding actuator 54 is connected to the feeding plate 52 and is used to drive the feeding plate 52 to move along the feeding guide rail 53 to push the bottom sheet material 11 in the material preparation bin 51 to move along the X direction and feed it onto the intermediate material platform 42. A limit sensor switch 55 is provided at the end of the feeding guide rail 53 away from the material platform to sense the position of the feeding plate 52 and control the action of the feeding actuator 54. In this embodiment, the bottom plate 511 of the material preparation bin 51 is positioned a certain distance above the table surface of the machine base 10. The material pushing guide rail 53 is located below the material preparation bin 51. The material pushing actuator 54 is a cylinder, which is fixedly installed below the machine base 10 along the X direction. The piston rod of the material pushing actuator 54 is fixedly connected to the material pushing plate 52 through a connector.

[0034] like Figure 6 and Figure 7 As shown, the material platform is also equipped with a length positioning device, a width positioning device, a material ejection device, and a material pressing device.

[0035] The length positioning device is used to adjust the feeding position of the sheet 11 in the X direction according to the length of the sheet 11 in the X direction. The length positioning device includes a positioning baffle 61 and at least one second lead screw motor 62. The positioning baffle 61 is arranged perpendicular to the X direction and is located at the end of the predetermined feeding stroke of the sheet 11 on the intermediate material table 42. The second lead screw motor 62 is connected to the positioning baffle 61 and is used to drive the positioning baffle 61 to move along the X direction to adjust the final feeding position of the sheet 11. Specifically, the length positioning device also includes a mounting base 63, a guide structure, and two second lead screw motors 62. The mounting base 63 is fixed on the intermediate material platform 42. The positioning baffle 61 is connected to the side of the mounting base 63 near the material preparation bin 51 via the guide structure. The second lead screw motor 62 is an externally driven lead screw motor. The body of the second lead screw motor 62 is fixed to one of the positioning baffle 61 and the mounting base 63, and the external nut is fixed to the other. When the second lead screw motor 62 works, it drives the lead screw shaft to rotate, and the external nut moves linearly along the lead screw shaft, thereby causing the positioning baffle 61 to move forward or backward relative to the mounting base 63 in the X direction to accommodate sheet metal 11 of different X-direction lengths. In this embodiment, the body of the second lead screw motor 62 is fixed to the positioning baffle 61, the external nut is fixed to the mounting base 63, the lead screw shaft passes through the positioning baffle 61 and is connected to the external nut, and the guide structure is a guide rod and guide sleeve structure arranged in the X direction, wherein the guide rod is fixedly connected to the positioning baffle 61, and the guide sleeve is fixedly connected to the mounting base 63.

[0036] The width positioning device and the top-loading device are located on both sides of the sheet metal 11 to be sliced ​​along the Y direction. Two sets of width positioning devices are installed on the first side platform 41. Each set includes a positioning rod 65, a guide member 66, and a first lead screw motor 67. The two first lead screw motors 67 are fixedly installed on the first side platform 41 and are located on the sides of both ends of the sheet metal 11 along the X direction. The first lead screw motors 67 are through-shaft type lead screw motors, and their lead screw shafts are arranged along the Y direction. The positioning rod 65 is slidably mounted on the guide member 66 along the Y direction and is located between the lead screw shaft of the first lead screw motor 67 and the sheet metal 11 to be sliced. The two ends of the positioning rod 65 correspond to the ends of the lead screw shafts of the first lead screw motor 67 and the sides of the sheet metal 11 to be sliced, respectively. The guide member 66 is fixed to the first side platform 41.

[0037] The feeding device includes two feeding actuators 68 mounted parallel to each other along the Y-axis on the second side platform 43. The output ends of the two feeding actuators are respectively aligned with the sides of the two ends of the X-axis length of the sheet metal 11. The action of the two feeding actuators 68 can push the sheet metal 11 to be sliced ​​along the Y-axis until it abuts against one end of the two positioning rods 65, and then further push it until the other end of the positioning rods 65 abuts against the end of the lead screw shaft of the first lead screw motor 67. Therefore, the ends of the lead screw shafts of the two first lead screw motors 67 can respectively limit the Y-axis position of the two ends of the sheet metal 11 to be sliced ​​in the X-axis direction, thereby limiting the width of the slices 12 cut out in the X-axis direction. The control module is electrically connected to the first lead screw motor 67 and the feeding actuators 68, and the control module is equipped with a control unit for controlling the alternating extension and retraction of the two lead screw shafts. The control module controls the alternating extension and retraction of the lead screw shafts of the two first lead screw motors 67 according to the preset slicing width parameters. With the interaction of the positioning rods and the feeding device, slices 12 with opposite width and narrow ends can be cut alternately without flipping the sheet metal 11 or requiring manual operation. In this embodiment, both top material actuators 68 are cylinders, which are fixedly installed on the connecting plate 46 on the aforementioned intermediate material platform 42. The piston rod of the cylinder passes through the connecting plate 46 and is aligned with the plate 11. During operation, the piston rod extends to push the plate 11.

[0038] The pressing device consists of two sets. Each set includes at least one pressing actuator 71 fixedly mounted on the material platform and a pressing plate 72 connected to the output end of the pressing actuator 71. The pressing actuator 71 drives the pressing plate 72 to move downward along the Z-axis, vertically pressing the sheet material 11 onto the material platform. The pressing plates 72 of the two sets of pressing devices are respectively arranged on both sides of the cutting path to press the sheet material 11 on both sides of the cutting path during the cutting process, thereby improving the stability of the cutting process. Specifically, the pressing device also includes pressing brackets 73. The pressing brackets 73 of the two sets of pressing devices are respectively fixedly mounted on the intermediate material platform 42 and the first side material platform 41, and the pressing actuators 71 are fixedly mounted on the pressing brackets 73. In this embodiment, the pressing actuator 71 is a cylinder. Two to three cylinders are installed side by side along the X-axis on each pressing bracket. A pressing plate 72 is fixedly connected to the piston rod end of each cylinder, further improving the stability of the cutting process. In this embodiment, in order to further improve the stability of the cutting process, an X-direction pressing cylinder 74 is also provided on the material platform to press the plate 11 along the X direction. The X-direction pressing cylinder 74 is fixed on the intermediate material platform 42 near the infeed gap 44 and the material preparation bin 51. During cutting, the X-direction pressing cylinder 74 extends to press the plate 11 onto the positioning baffle 61 of the length positioning device.

[0039] The output system is used to output and sort the cut sheet material 12, such as Figure 8As shown, the feeding system includes a stacking platform 81, a clamping device, a feeding guide rail 82, and a feeding drive device. The feeding guide rail 82 is fixedly arranged along the X direction. The stacking platform 81 is fixedly installed on the machine base 10, located on one side of the feeding guide rail in the Y direction. The stacking platform 81 has at least two stacking positions 811, and the upper surface of the stacking platform 81 is not higher than the upper surface of the material table. The clamping device is used to clamp and release the cut sheet material 12. The clamping device is slidably arranged on the feeding guide rail 82 and is driven by the feeding drive device to reciprocate along the feeding guide rail 82 to transport the sheet material 12 to the stacking platform 81. The control module is electrically connected to the feeding drive device and the clamping device, and the control module is equipped with a control unit for controlling the stacking position of the sheet material 12. The control module controls the feeding drive device to drive the clamping device to alternately transport the sheet material 12 to the two stacking positions 811 on the stacking platform 81 according to preset parameters, so that sheet materials 12 with different widths at both ends in the X direction can be stacked in a classified manner.

[0040] like Figure 10 and Figure 11As shown, the clamping device includes a base 83, a clamping assembly 84, and a lifting module 85. The base 83 is slidably mounted on the discharge guide rail 82 via a slider and connected to the discharge drive device. The lifting module 85 includes a lifting plate 851 movably connected above the base 83 and a lifting actuator 852 for driving the lifting plate 851 to move up and down in the Z direction. The clamping assembly 84 includes a chuck body 841 for clamping in the Y direction and a clamping actuator 842 for driving the chuck body 841 to clamp. The clamping assembly 84 is at least indirectly mounted on the lifting plate 851. The lifting module 85 is used to drive the clamping assembly 84 to move up and down in the Z direction. After the clamping device transports and stacks the sheet material 12 to a predetermined position on the stacking platform 81, the lifting module 85 drives the clamping assembly 84 to rise, and then the discharge drive device drives the clamping device back to the initial position, thereby avoiding the sheet material 12 already stacked on the stacking platform 81. In this embodiment, the lifting plate 851 is also provided with a Y-direction telescopic rod 853. The clamping assembly 84 is fixedly installed on the telescopic rod 853. The telescopic rod 853 is slidably connected to the lifting plate 851 through a slider fixed on the lifting plate 851, and the extension length of the telescopic rod 853 is limited by a limiting rod, thereby adjusting the Y-direction position of the clamping assembly 84 so that the clamping head 841 is aligned with the cut sheet material 12. The clamping assembly 84 also includes a mounting frame 843 and a linkage mechanism 844. The mounting frame 843 is fixed to the telescopic rod 853, and the clamping actuator 842 is fixedly installed on the mounting frame 843. In this embodiment, the clamping actuator 842 is a cylinder. The chuck body 841 includes a stationary clamping plate 845, a movable clamping plate 846, a pin 847, and a rotating handle 848. The stationary clamping plate 845 is formed by extending from the side plate of the mounting bracket 843. The movable clamping plate 846 is arranged opposite to the stationary clamping plate 845. The pin 847 is fixed to the mounting bracket 843. The middle part of the rotating handle 848 is hinged to the pin 847. One end of the rotating handle 848 is connected to the movable clamping plate 846, and the other end is connected to one end of the linkage mechanism 844. The other end of the linkage mechanism 844 is hinged to the piston rod end of the clamping actuator 842. The clamping actuator 842 drives the rotating handle 848 through the linkage mechanism 844 to move the movable clamping plate 846 closer to the stationary clamping plate 845 to clamp the sheet material 12. The movable clamping plate 846 and the rotating handle 848 are hinged at one end, so that when clamping sheet materials 12 of different thicknesses and slopes, they can be rotated to make the clamping surface fit the surface of the sheet material 12, making the clamping more stable.

[0041] like Figure 8As shown, the discharge drive device includes a second drive motor 86, a pulley transmission mechanism, and a transmission block 87. The pulley transmission mechanism includes a drive wheel 881, a driven wheel 882, and a transmission belt 883 tensioned on the drive wheel 881 and the driven wheel 882. The drive wheel 881 and the driven wheel 882 are respectively arranged on the sides of both ends of the discharge guide rail 82. The transmission belt 883 is parallel to the discharge guide rail 82. The transmission block 87 is fixed on the transmission belt 883 and fixedly connected to the base 83 of the clamping device. The output shaft of the second drive motor 86 is connected to the drive wheel 881, driving the drive wheel 881 to rotate and drive the transmission belt 883 to move, thereby driving the clamping device to move along the discharge guide rail 82.

[0042] like Figure 9 As shown, the discharge system also includes at least one set of material handling devices. Each set of material handling devices includes a material handling plate 91 and a material handling actuator 92. A square hole 93 is provided on the stacking platform 81. The material handling plate 91 is arranged perpendicular to the Y direction in the square hole 93. The material handling actuator 92 is fixedly installed below the stacking platform 81 and connected to the material handling plate 91. It is used to drive the material handling plate 91 away from the discharge guide rail 82 along the Y direction, thereby pushing the outermost sheet material 12 on the stacking platform 81 in the X direction to move inward and push the inner sheet material 12 to achieve alignment and sorting. In this embodiment, there are two sets of material handling devices, and two square holes 93 are also provided on the stacking platform 81, corresponding to two half-areas distributed along the X direction on the stacking platform 81, respectively, for sorting two sets of sheet materials 12.

[0043] like Figure 1 and Figure 2 As shown, a cabinet 13 is located below the machine base 10. The first drive motor 22, the pusher actuator 54, the chip collection box 25, the dust suction pipe 26, and the discharge hopper 28 are all installed in the cabinet 13. A machine cover 14 is also mounted on the machine base 10. The feeding system, material table, feeding device, cutting device, and discharging system are all located in the space inside the machine cover 14. A touch screen 15 is located in front of the machine cover 14 for inputting preset parameters and viewing the machine's operating status. Signal lights 16 are installed on the top of the machine cover 14 to display the working status, facilitating workshop management.

[0044] The automatic slicing machine for chopstick raw materials of the present invention is suitable for slicing chopsticks of different sizes. The specific working process is as follows: 1. Stack the sheet material 11 in the material preparation bin 51, set the parameters such as the X-direction length of the sheet material 11 and the width of both ends of the sheet material 12 on the control panel, start the machine, at this time the material table and clamping device are in the initial position, the length positioning device and the width positioning device will automatically adjust to the set position, and the first drive motor 22 drives the saw blade 21 to start rotating. 2. Feeding: The pusher actuator 54 drives the pusher plate 52 to move along the pusher guide rail 53, thereby pushing the bottom plate 11 in the preparation bin 51 to move along the X direction and feed it to the intermediate material platform 42. The plate 11 stops after being fed to the preset position (the position defined by the positioning baffle 61 of the length positioning device). The pusher actuator 54 drives the pusher plate 52 to reset until it touches the second travel induction switch 55. 3. Top Material Pressing: The piston rod of the top material actuator 68 extends and pushes the plate 11 to be sliced ​​along the Y direction until it abuts against one end of the two positioning rods 65 of the width positioning device. Then it pushes it further until the other end of the positioning rods 65 abuts against the end of the lead screw shaft of the first lead screw motor 67. Then, the two sets of pressing actuators 71 simultaneously drive the pressing plate 72 to move downward along the Z direction to vertically press the plate 11 onto the material table. The pressing plates 72 of the two pressing devices press on both sides of the cutting path respectively. At the same time, the piston rod of the top material actuator 68 retracts. 4. Feeding and slicing: The feed actuator 32 drives the material table to move along the feed guide rail 31. The saw blade 21 passes through the feed gap 44 between the middle material table 42 and the first side material table 41 and cuts the plate material 11 in the X direction. When the material table moves to the end of the stroke, the saw blade 21 has cut a piece of material 12 that is thick at one end and thin at the other end. The tail end of the piece of material 12 is aligned with the chuck body 841 of the clamping assembly 84. 5. Sheet Retrieval and Stacking: The clamping actuator 842 drives the clamping plate 846 to clamp the sheet 12. Then, a set of pressing actuators 71 pressing on one side of the sheet 12 drives the pressing plate 72 to retract. At the same time, the feed actuator 32 drives the material table to return, and the retraction actuator 45 drives the intermediate material table 42 away from the first side material table 41 to avoid the saw blade 21. Also at the same time, the second drive motor 86 drives the clamping device to move along the discharge guide rail 82 to the first stacking position 81 of the stacking table 81 through the pulley transmission mechanism. 1. The clamping actuator 842 drives the clamping plate 846 to release, and the sheet material 12 is placed on one half of the area distributed along the X direction on the stacking table 81. The lifting module 85 drives the clamping assembly 84 to rise, and then the second drive motor 86 drives the clamping device to return to the initial position. The clamping assembly 84 also descends to the initial position to prepare for the next sheet picking. The material handling actuator 92 corresponding to this half area drives the material handling plate 91 to move away from the discharge guide rail 82 along the Y direction, thereby pushing the sheet material 12 to move inward to the stacking table 81. 6. Secondary Slicing and Stacking: After the material table returns to the initial position, a set of pressing actuators 71 pressing on one side of the remaining sheet material 11 drives the pressing plate 72 to retract. At the same time, the screw shafts of the two first screw motors 67 of the width positioning device alternately extend and retract to the preset position, repeating the material lifting, pressing, and feeding slicing process of steps 3 and 4, and cutting out sheet material 12 with the coarse and fine ends swapped with the previous sheet material 12; repeat the sheet picking, return blade retraction, stacking, and sorting process of step 5. The difference is that when stacking, the second drive motor 86 drives the clamping device to move to the second stacking position 811 of the stacking table 81, and places the sheet material 12 of this time on the other half of the stacking table 81. When sorting, the sorting device corresponding to the other half of the area also operates. 7. Repeat steps 3 to 6 until one sheet 11 has been cut. 8. Repeat steps 2 to 7 in a cycle to slice the sheet material 11 in the preparation bin 51 in sequence. As the sheet material 12 on the stacking table 81 increases, the material handling device will push the outermost sheet material 12 on the stacking table 81 in the X direction to move inward and squeeze the inner sheet material 12 to achieve alignment and sorting.
