Description

Technical Field

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

[0002] With the global spread of Chinese culinary culture, demand for chopsticks is growing. Simultaneously, advancements in production technology are driving the automation and efficiency of chopstick production equipment, a key trend in the industry. However, the production of chopsticks in China, particularly traditional chopsticks with large and small ends, still relies primarily on manual labor. The production process primarily involves slicing, branching, planing, polishing, and de-edging. Slicing involves cutting the wood into narrow sheets with one end wider than the other. Typically, workers place the side of the board against a beveled baffle and push it toward the saw blade, creating a narrow sheet. The board is then flipped over and the same side is placed against the baffle again to cut the next narrow sheet. This repetitive process is labor-intensive and inefficient, making it difficult to ensure consistent sheet sizes and prone to hand injuries.

[0003] In order to improve production efficiency, some automated equipment has been developed. For example, Chinese patent publication number CN203792458U discloses an automatic chopstick production machine, which includes a frame, which is composed of multiple groups of bodies. Each group of bodies is composed of a feeding system, a feeding system, a sawing mechanism, and a discharging system. The fully automated structure is used to complete the finished product processing of chopsticks through the feeding system, the feeding system, the sawing mechanism, and the discharging system. The feeding system can be equipped with multiple groups of pressing mechanisms. The unit completes one action and can simultaneously complete multiple chopsticks. The work efficiency is extremely high, no worker operation is required, and the degree of automation is high. However, this automatic chopstick production machine still cannot automatically cut out the wide and narrow ends of the blanks, and the finished products after cutting fall directly into the hopper. The finished products are disorganized and still need to be manually reorganized. Utility Model Content

A signal light 16 for displaying the working status is installed on the top of the cover 14 to facilitate workshop management.

[0058] The utility model of the automatic chopstick raw material slicing machine is suitable for slicing the raw materials of large and small head chopsticks. The specific working process is as follows:

[0059] 1. Stack the sheets 11 into the preparation bin 51, set the X-axis length of the sheets 11 and the width of the sheets 12 at both ends on the control panel, and start the machine. At this time, the material table and the clamping device are in 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;

[0060] 2. Feeding: The push actuator 54 drives the push plate 52 to move along the push guide rail 53, thereby pushing the sheet material 11 at the bottom layer in the preparation bin 51 to move along the X direction and feed it onto the intermediate material table 42. The sheet material 11 stops after being fed to the preset position (the position defined by the positioning baffle 61 of the length positioning device). The push actuator 54 drives the push plate 52 to return to its original position until it touches the second stroke sensing switch 55.

[0061] 3. Ejecting and pressing the material: The piston rod of the ejecting 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 it until the other end of the positioning rod 65 abuts against the end of the screw shaft of the first screw motor 67. Then, the two sets of pressing actuators 71 simultaneously drive the pressing plates 72 to move downward along the Z direction to press the sheet material 11 vertically on the material table. The pressing plates 72 of the two sets of pressing devices are pressed on both sides of the cutting path respectively. At the same time, the piston rod of the ejecting actuator 68 retracts;

[0062] 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, cutting the plate 11 along the X direction. When the material table moves to the end of its stroke, the saw blade 21 has cut a piece of material 12 with one end thicker and the other end thinner. The tail end of the piece 12 is aligned with the chuck body 841 of the clamping assembly 84.

[0063] 5. Take out the sheet and stack the material: the clamping actuator 842 drives the dynamic clamping plate 846 to clamp the sheet 12, and then a set of pressing actuators 71 pressed on one side of the sheet 12 drives the pressing plate 72 to retract, and at the same time the feed 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 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 movable clamping plate 846 to release, and the sheet 12 is placed on the stacking table 81 in one half area distributed along the X direction. 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 removal; the material sorting actuator 92 corresponding to this half area drives the material sorting plate 91 away from the discharge guide rail 82 in the Y direction, thereby pushing the sheet 12 to move toward the inner side of the stacking table 81;

[0064] 6、Secondary slicing code material: After the material table returns to the initial position, the group of pressing material actuators 71 pressed on the remaining plate material 11 on one side drives the pressing plate 72 to retract, and the screw shafts of the two first screw motors 67 of the width positioning device are alternately retracted to the preset position. Repeat the material lifting, material pressing, and feeding slicing process of steps 3 and 4, and cut out the slice material 12 with the coarse and thin ends reversed; Repeat the slice taking, return cutting, material coding, and material sorting process of step 5, except that when coding, the second driving motor 86 drives the material clamping device to move to the second coding position 811 of the coding table 81, and places the slice material 12 on the other half area of the coding table 81. When sorting, the corresponding sorting device in the other half area also acts;

[0065] 7、Repeat steps 3 to 6 in a cycle until a plate material 11 is cut off;

[0066] 8、Repeat steps 2 to 7 in a cycle to slice the plate material 11 in the material preparation bin 51. As the slice material 12 on the coding table 81 increases, the sorting device will push the slice material 12 on the outermost side of the coding table 81 inward to align and arrange the slice material 12 on the inner side.

[0067] It can be understood that for those skilled in the art, other various corresponding changes and deformations can be made according to the technical concept of the present application, and all these changes and deformations shall belong to the protection scope of the present application.
