Description

Technical Field

[0001] The invention relates to the technical field of chopstick processing equipment, in particular to an automatic chopstick raw material slicing machine. Background Art

[0002] With the globalization of Chinese catering culture, the demand for chopsticks is growing. At the same time, the continuous advancement of production technology has promoted the development of chopstick production equipment towards automation and high efficiency, which has become an important trend in the development of the industry. However, at present, the production of domestic chopsticks, especially traditional large and small head chopsticks, still mainly relies on manual operation. The production process of large and small head chopsticks mainly includes the processes of slicing, branching, planing, polishing and de-edging. In the slicing process, the wood material needs to be cut into a piece with one end wide and the other end narrow. When the raw material is sliced, the worker usually puts the side of the wood against the inclined baffle and pushes the wood toward the saw blade against the inclined baffle, thereby cutting out a piece with one end wide and the other end narrow. Then turn the wood over, put the same side against the inclined baffle again, and cut the next piece of wide and narrow head. Repeating flipping and cutting is not only labor-intensive and inefficient, but also difficult to ensure the consistency of the size of each piece by manual operation, and it is easy to cut your hands.

[0003] In order to improve production efficiency, some automated equipment has been developed, such as the Chinese patent with publication number CN203792458U, which discloses an automatic chopstick production machine, which includes a frame, which is composed of multiple groups of machine bodies, each group of machine bodies is composed of a feeding system, a feeding system, a sawing mechanism and a discharging system, and adopts a fully automated structure. The finished product processing of chopsticks is completed through the feeding system, the feeding system, the sawing mechanism and the discharging system. The feeding system can be arranged with multiple groups of pressing mechanisms. The machine unit completes one action and can complete multiple chopsticks at the same time. The work efficiency is extremely high, no worker operation is required, and the degree of automation is high. However, the automatic chopstick production machine still cannot automatically cut out the wide and narrow end blanks, and the finished products after cutting fall directly into the hopper. The finished products are messy and still need to be manually rearranged. Summary of the invention

The intermediate material table 42 is arranged to be fixed with the first and second side material tables 41 and 43 in the X direction, and can be driven by the retracting actuator 45 in the Y direction to reciprocate between the first and second side material tables 41 and 43. In this embodiment, in order to ensure the stability of the material table during operation, two feed guide rails 31 are provided on the side corresponding to the first side material table 41, so there are three feed guide rails 31 in total; in this embodiment, the retracting actuator 45 is a cylinder, which is fixedly installed on the second side material table 43 along the Y direction, and a connecting plate 46 is fixedly provided on the table surface of the middle material table 42. The piston rod of the retracting actuator 45 is connected to the connecting plate 46.

[0033] The feeding system is used to prepare the material and push the sheet material 11 to the intermediate material table 42. Figure 5As shown, the feeding direction of the automatic slicing machine for chopstick raw materials in this embodiment is the X direction, and the feeding system includes a preparation bin 51 and a pushing assembly.

The pushing actuator 54 is connected to the pushing plate 52, and is used to drive the pushing plate 52 to move along the pushing guide rail 53 to push the bottom layer of the sheet material 11 in the preparation bin 51 to move along the X direction to feed the intermediate material table 42. A travel sensing switch 2 55 is arranged at the end of the pushing guide rail 53 away from the material table, which is used to sense the position of the pushing plate 52 and control the action of the pushing actuator 54.

[0034] like Figure 6 and Figure 7 As shown, the material table is also provided with a length positioning device, a width positioning device, a material pushing device and a material pressing device.

[0035] The length positioning device is used to adjust the feeding position of the sheet material 11 in the X direction according to the length of the sheet material 11 in the X direction. The length positioning device includes a positioning baffle 61 and at least one second screw motor 62. The positioning baffle 61 is arranged perpendicular to the X direction and is located at the end point of the predetermined feeding stroke of the sheet material 11 on the intermediate material table 42. The second 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 material 11. Specifically, the length positioning device also includes a mounting seat 63 and a guide structure 64. There are two second screw motors 62. The mounting seat 63 is fixed on the intermediate material table 42. The positioning baffle 61 is connected to the side of the mounting seat 63 close to the material preparation bin 51 through the guide structure 64. The second screw motor 62 is an externally driven screw motor. The body of the second screw motor 62 is fixed to one of the positioning baffle 61 and the mounting seat 63, and the external nut is fixed to the other one. The second screw motor 62 drives the screw shaft to rotate when it works, and the external nut moves linearly along the screw shaft, thereby causing the positioning baffle 61 to move forward or backward in the X direction relative to the mounting seat 63 to adapt to sheet materials 11 of different X-direction lengths. In this embodiment, the body of the second screw motor 62 is fixed to the positioning baffle 61, the external nut is fixed to the mounting seat 63, the screw shaft passes through the positioning baffle 61 and is connected to the external nut, and the guide structure 64 is a guide rod and guide sleeve structure arranged along 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 seat 63.

[0036] The width positioning device and the material ejecting device are respectively located on both sides of the Y direction of the sheet material 11 to be sliced. There are two groups of width positioning devices, which are installed on the first side material table 41. Each group of width positioning devices includes a positioning rod 65, a guide member 66 and a first screw motor 67. The two first screw motors 67 are fixedly installed on the first side material table 41 and are respectively located on the sides at both ends of the length of the sheet material 11 in the X direction. The first screw motor 67 is a through-axis screw motor, and its screw shaft is arranged along the Y direction. The positioning rod 65 is slidably arranged on the guide member 66 along the Y direction and is located between the screw shaft of the first screw motor 67 and the sheet material 11 to be sliced. The two ends of the positioning rod 65 correspond to the ends of the screw shaft of the first screw motor 67 and the side of the sheet material 11 to be sliced, respectively, and the guide member 66 is fixed to the first side material table 41.

[0037] The ejection device includes two ejection actuators 68 installed in parallel on the second side material table 43 along the Y direction. The output ends of the two ejection actuators are respectively aligned with the sides of the two ends of the length of the sheet material 11 in the X direction. The two ejection actuators 68 can push the sheet material 11 to be sliced ​​along the Y direction to abut against one end of the two positioning rods 65, and then further push it to the other end of the positioning rod 65 to abut against the end of the screw shaft of the first screw motor 67. Therefore, the ends of the screw shafts of the two first screw motors 67 can respectively limit the Y-direction positions of the two ends of the sheet material 11 to be sliced ​​in the X direction, thereby limiting the width of the cut sheet material 12 in the X direction.

The clamping actuator 842 drives the rotating handle 848 through the connecting rod mechanism 844 to drive the movable clamping plate 846 to approach the static clamping plate 845 to clamp the sheet material 12. The movable clamping plate 846 and one end of the rotating handle 848 are hinged, so that when clamping sheets 12 of different thicknesses and slopes, they can be rotated so that the clamping surface fits the surface of the sheet 12, making the clamping more stable.

In this embodiment, there are two sets of material sorting devices, and two square holes 93 are also opened on the material stacking table 81, which correspond to the two half-side areas distributed along the X direction on the material stacking table 81, respectively, for sorting two sets of sheet materials 12.

[0044] The chopstick raw material automatic slicing machine of the present invention is suitable for slicing raw materials of large and small head chopsticks, and the specific working process is as follows: 1. Stack the sheet materials 11 into the material preparation bin 51, set the X-axis length of the sheet materials 11, the width of the two ends of the sheet materials 12 and other parameters on the control panel, start the machine, at this time, the material table and the clamping device are at the initial position, the length positioning device and the width positioning device are automatically adjusted to the set position, and the first drive motor 22 drives the saw blade 21 to start rotating; 2. Feeding: The push actuator 54 drives the push plate 52 to move along the push guide rail 53, thereby pushing the sheet 11 at the bottom layer in the preparation bin 51 to move along the X direction and feed it to the intermediate material table 42. The sheet 11 stops after being fed to the preset position (the position defined by the positioning baffle 61 of the length positioning device), and the push actuator 54 drives the push plate 52 to reset until it touches the stroke sensing switch 2 55; 3. Material pushing and pressing: The piston rod of the material pushing actuator 68 extends to push the sheet material 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, and then further pushes until the other end of the positioning rod 65 abuts against the end of the screw shaft of the first screw motor 67, and then the two sets of material pressing actuators 71 simultaneously drive the material pressing plates 72 to move downward along the Z direction to vertically press the sheet material 11 on the material table, and the material pressing plates 72 of the two sets of material pressing devices are pressed on both sides of the cutting path respectively, and at the same time, the piston rod of the material pushing actuator 68 retracts; 4. Feeding and slicing: the feed actuator 32 drives the material table to move along the feed guide rail 31, and 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 along the X direction. When the material table moves to the end of the stroke, the saw blade 21 has cut a sheet material 12 with one end thick and the other end thin, and the tail end of the sheet material 12 is just aligned with the chuck body 841 of the clamping assembly 84; 5. Take the sheet and stack the material: the clamping actuator 842 drives the movable clamping plate 846 to clamp the sheet 12, and then a group of pressing actuators 71 pressed on one side of the sheet 12 drive the pressing plate 72 to retract, and at the same time the feeding actuator 32 drives the material table to return, and the retracting actuator 45 drives the middle material table 42 away from the first side material table 41 to avoid the saw blade 21; at the same time, the second driving 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 movable clamping plate 846 to release, and the sheet 12 is placed on the half area of ​​the stacking table 81 distributed along the X direction. The lifting module 85 drives the clamping assembly 84 to rise, and then the second driving 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 sorting actuator 92 corresponding to the half area drives the material sorting plate 91 to move away from the discharge guide rail 82 along the Y direction, thereby pushing the sheet 12 to move to the inner side of the stacking table 81; 6. Secondary slicing and stacking: After the material table returns to the initial position, a group of pressing actuators 71 pressed on one side of the remaining sheet 11 drives the pressing plate 72 to retract, and at the same time, the screw shafts of the two first screw motors 67 of the width positioning device are alternately extended and retracted to the preset positions, and the processes of pushing, pressing, feeding and slicing in steps 3 and 4 are repeated to cut out a sheet 12 whose coarse and thin ends are swapped with those of the previous sheet 12; the processes of taking out the sheet, returning the knife, stacking and sorting in step 5 are repeated, except that when stacking, the second driving motor 86 drives the clamping device to move to the second stacking position 811 of the stacking table 81, and places the sheet 12 on the other half area of ​​the stacking table 81. When sorting, the sorting device corresponding to the other half area is also actuated; 7. Repeat steps 3 to 6 in a loop until a sheet 11 is cut; 8. Repeat steps 2 to 7 in a loop to slice the sheet material 11 in the material preparation bin 51 in turn. As the number of sheets 12 on the stacking table 81 increases, the material sorting device will push the outermost sheet 12 on the stacking table 81 in the X direction to move inward and squeeze the inner sheet 12 to achieve alignment.
