Description

Technical Field

[0001] The utility model relates to the technical field of packaging box processing, in particular to a trimming machine used for processing wood packaging boxes. Background Art

[0002] By trimming, excess material on the edge of the box can be removed, making the edge more neat, thereby improving the overall quality and appearance of the box. Reduce waste: The waste removed during the trimming process can be reused, reducing material waste and thus saving costs.

[0003] For example, the publication number "CN216466446U" discloses a paper packaging box cutting device. This utility model forms a trimming mechanism by arranging a cutter in the paper packaging box cutting device. The trimming device is driven by a motor to operate the parts. The pressure plate will press and fix the delivered cardboard. The edge to be cut is then cut off by the cutter, thereby completing the trimming work. Mechanical cutting replaces manual cutting, which can improve cutting efficiency, ensure cutting accuracy, reduce labor use, and reduce production and processing costs. However, this paper packaging box cutting device uses a spring to press the cardboard and transports the cardboard through a conveyor belt. The conveyor belt drives the cardboard for cutting. The cardboard is prone to movement during cutting and is not stable, which increases the probability of cutting errors and thus increases production costs. At the same time, this paper packaging box cutting device requires workers to level and position the cardboard, which consumes a lot of workers' time and reduces work efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that a paper packaging box cutting device compresses the cardboard by a spring and transports the cardboard by a conveyor belt, and the conveyor belt drives the cardboard to be cut. The cardboard is easy to move during cutting and has no stability, which increases the probability of cutting errors and thus increases production costs. At the same time, the paper packaging box cutting device requires workers to level and position the cardboard, which consumes a lot of workers' time and thus reduces work efficiency. A trimming machine for wood packaging box processing is proposed.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A trimming machine for processing wood packaging boxes is designed, comprising a first shell, wherein the lower end of the outer wall of the first shell is fixedly connected to a second shell, a positioning mechanism is provided inside the second shell, a pushing mechanism is provided inside the first shell, a bent plate is fixedly connected to the left side of the upper end of the first shell, the outer wall of the bent plate is slidably connected to the first slider, the lower end of the first slider is fixedly connected to a multi-stage cylinder, the output end of the multi-stage cylinder is fixedly connected to a pressure plate, and a vertical plate is symmetrically fixedly connected to the right side of the outer wall of the first shell.

[0007] Preferably, the outer sides of the vertical plates are fixedly connected to first motors, the output shafts of the first motors are fixedly connected to cutting blades, and the output shafts of the first motors are rotatably connected to the vertical plates via bearings.

[0008] Preferably, the pushing mechanism includes a second motor, the output shaft of the second motor is fixedly connected to a wire roller, the wire roller is slidably connected to the pull wire, the end of the pull wire is fixedly connected to a push plate, the lower end of the inner wall of the push plate is slidably connected to the first slide rod, the outer wall of the first slide rod is sleeved with a spring, the two ends of the spring are respectively fixedly connected to the push plate and the first shell, and the ends of the first slide rod are fixedly connected to the first shell.

[0009] Preferably, the outer wall of the second motor is fixedly connected to the first housing, and the output shaft of the second motor is rotatably connected to the first housing via a bearing.

[0010] Preferably, the positioning mechanism includes a third motor, the output shaft of the third motor is fixedly connected to the first gear, both sides of the first gear are meshed with the second gear, the rotating shaft of the second gear is fixedly connected to a threaded rod, the ends of the threaded rod are rotatably connected to the second outer shell through bearings, the rotating shaft of the first gear is rotatably connected to the second slide rod through bearings, the outer walls of the threaded rods are threadedly connected to the second slider, and the inner walls of the second slider are slidably connected to the second slide rod.

[0011] Preferably, the outer wall of the third motor is fixedly connected to the second housing, and the rotating shaft of the second gear is rotatably connected to the second housing via a bearing.

[0012] The utility model proposes a trimming machine for processing wood packaging boxes, which has the beneficial effect that: through the cooperation of the pushing mechanism and the hydraulic cylinder, the output shaft of the second motor rotates forward to drive the wire roller to rotate, thereby driving the pull wire to move to the right, and the pull wire moves to the right, and the pull wire moves to the right and drives the push plate to move to the right. Because the limit of the first slide bar can move horizontally, the push plate moves to the right to compress the spring and the push plate moves to the right to apply a rightward thrust to the wooden board. Because the wooden board is pressed by the pressure plate, when the thrust is applied to the wooden board, it drives the first slider to move to the right, and the first slider moves to the right and drives the multi-stage cylinder and the pressure plate to move to the right, ensuring that the pressure plate always presses the wooden board to prevent the wooden board from moving during cutting. Through the cooperation of the pushing mechanism and the multi-stage cylinder, the displacement of the wooden board during processing can be reduced, thereby reducing the probability of cutting errors, reducing the generation of waste and thus reducing production costs.

[0013] Through the cooperation of the positioning mechanism and the push plate, the output shaft of the third motor rotates to drive the first gear to rotate, thereby driving the second gear to rotate. The rotation of the second gear drives the two threaded rods to rotate. Because the threads of the two threaded rods are in opposite directions, the movement directions of the second slider are opposite. The third motor rotates forward and the two threaded rods drive the two second sliders to move inward. When the second slider moves inward, when the inner ends of the two second sliders are tightly against the wooden board, the output shaft of the third motor is controlled to reverse, so that the two second sliders move outward to the initial position and then stop the third motor, and then start the multi-stage cylinder. The output end of the multi-stage cylinder extends to drive the pressure plate to move downward. When the pressure plate is tightly against the wooden board, the multi-stage cylinder is stopped, thereby realizing the positioning and leveling of the wooden board. There is no need for the staff to manually level and center it. They only need to place the wooden board, which saves the staff's time for leveling and centering, thereby improving work efficiency.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] Refer to the attached Figure 1-6 :

[0023] In this embodiment, a trimming machine for processing wood packaging boxes includes a first housing 1. The surface of the first housing 1 is smooth to facilitate the movement of wooden boards. The lower end of the outer wall of the first housing 1 is fixedly connected to a second housing 3. A positioning mechanism 4 is provided inside the second housing 3. A pushing mechanism 2 is provided inside the first housing 1. A bending plate 5 is fixedly connected to the left side of the upper end of the first housing 1. The outer wall of the bending plate 5 is slidably connected to a first slider 6. The lower end of the first slider 6 is fixedly connected to a multi-stage cylinder 7. The output end of the multi-stage cylinder 7 is fixedly connected to a pressure plate 8.

[0024] The sliding of the first slider 6 drives the multi-stage cylinder 7 to slide, thereby driving the pressure plate 8 to slide. The right side of the outer wall of the first shell 1 is symmetrically fixed with a vertical plate 10. The outer side of the vertical plate 10 is fixedly connected to the first motor 9. The output shaft of the first motor 9 is fixedly connected to the cutting knife 11. The output shaft of the first motor 9 rotates to drive the cutting knife 11 to rotate. There is a groove under the cutting knife 11 to enable the cutting knife 11 to completely cut the wooden board. The output shaft of the first motor 9 is rotatably connected to the vertical plate 10 through a bearing.

[0025] Refer to the attached Figure 1-2 and 4-5:

[0026] The pushing mechanism 2 includes a second motor 201, the output shaft of the second motor 201 is fixedly connected to the wire roller 202, and the wire roller 202 is slidably connected to the pull wire 203. The output shaft of the second motor 201 rotates to drive the wire roller 202 to rotate, and the rotation of the wire roller 202 drives the pull wire 203 to move. The end of the pull wire 203 is fixedly connected to the push plate 204, and the lower end of the inner wall of the push plate 204 is slidably connected to the first slide bar 206. The movement of the pull wire 203 drives the push plate 204 to move, so that the push plate 204 moves along the first slide bar 206 and compresses the spring 205. The rebound of the spring 205 can reset the push plate 204. The outer wall of the first slide bar 206 is sleeved with a spring 205, and the two ends of the spring 205 are respectively fixedly connected to the push plate 204 and the first shell 1, and the ends of the first slide bar 206 are fixedly connected to the first shell 1. The outer wall of the second motor 201 is fixedly connected to the first shell 1, and the output shaft of the second motor 201 is rotatably connected to the first shell 1 through a bearing.

[0027] Refer to the attached Figure 1-3 :

[0028] The positioning mechanism 4 includes a third motor 401. The output shaft of the third motor 401 is fixedly connected to a first gear 402. Both sides of the first gear 402 are meshed with second gears 403. The output shaft of the third motor 401 rotates to drive the first gear 402 to rotate, thereby driving the two second gears 403 to rotate in the same direction. The rotation shafts of the second gears 403 are fixedly connected to threaded rods 404. The rotation of the second gears 403 drives the threaded rods 404 to rotate. The two threaded rods 404 have different thread directions. The ends of the threaded rods 404 are rotatably connected to the second housing 3 through bearings.

[0029] The rotating shaft of the first gear 402 is rotatably connected to the second slide rod 406 through a bearing, the outer walls of the threaded rod 404 are threadedly connected to the second slider 405, and the rotation of the two threaded rods 404 drives the second slider 405 to move in different directions respectively. The inner walls of the second slider 405 are slidably connected to the second slide rod 406, and the second slide rod 406 serves as a limit for the two second sliders 405. The outer wall of the third motor 401 is fixedly connected to the second shell 3, and the rotating shaft of the second gear 403 is rotatably connected to the second shell 3 through a bearing.

[0030] Working principle:

[0031] Preparation:

[0032] First, the staff will place the wood board that needs to be cut to the left side of the first shell 1 (such as Figure 1 ), placed against the push plate 404, and then start the third motor 401 (such as Figure 5 ), the output shaft of the third motor 401 rotates to drive the first gear 402 to rotate, thereby driving the second gear 403 to rotate, and the rotation of the second gear 403 drives the two threaded rods 404 to rotate. The two threaded rods 404 have opposite thread directions, so the movement directions of the second slider 405 are opposite. The third motor 401 rotates forward and the two threaded rods 404 drive the two second sliders 405 to move inward. The second sliders 405 move inward because the second slide bar 406 is limited so that they can move horizontally. The second slider 405 moves inward. When the inner ends of the two second sliders 405 are pressed against the wooden board, the output shaft of the third motor 401 is controlled to be reversed, so that the two second sliders 405 move outward to the initial position, then the third motor is stopped, and then the multi-stage cylinder 7 (such as Figure 1 ), the output end of the multi-stage cylinder 7 extends to drive the pressure plate 8 to move downward. When the pressure plate 8 is pressed against the wooden board, the multi-stage cylinder 7 is stopped to achieve the positioning and leveling of the wooden board. The two second sliders 405 are pressed against the wooden board so that the wooden board can remain horizontal and the center point is the same as the center of the first shell 1.

[0033] Cutting process:

[0034] Start the second motor 201 (as Figure 3 ), the output shaft of the second motor 201 rotates forward to drive the wire roller 202 to rotate, thereby driving the pull wire 203 to move right, the pull wire 203 moves right, and the pull wire 203 moves right, driving the push plate 204 to move right. Because the limit of the first slide bar 206 can move horizontally, the push plate 204 moves right to compress the spring 205. At the same time, the push plate 204 moves right to apply a rightward thrust to the wooden board. Because the wooden board is pressed by the pressing plate 8, when the thrust is applied to the wooden board, it will drive the first slider 6 to move right. The first slider 6 moves right, driving the multi-stage cylinder 7 and the pressing plate 8 to move right, ensuring that the pressing plate 8 always presses the wooden board to prevent the wooden board from moving during cutting;

[0035] At the same time, the first motor 9 is started (eg Figure 1 ), the output shaft of the first motor 9 rotates to drive the cutting knife 11 to rotate. When the wooden board passes through the cutting knife 11, the cutting knife will cut the excess part of the wooden board. After the whole wooden board is cut, the multi-stage cylinder 7 is started to retract the output end of the multi-stage cylinder 7 to the limit position. The staff takes the cut wooden board away and controls the output shaft of the second motor 202 to reverse so that the wire roller 202 releases the wire 203, and the pulling force of the pull rod 203 on the push plate 204 disappears. The spring 205 rebounds and drives the push plate 204 to reset. When the push plate 204 is reset, the second motor 201 is stopped. The staff cleans up the waste and reloads it and repeats the above operation to continue processing. After all is completed, all power supplies can be turned off.
