Description

Technical Field

[0001] This utility model relates to the field of plywood production, and in particular to a single-layer two-piece bamboo cutting device. Background Technology

[0002] Plywood is a sheet-like material made of bamboo strips. During processing, thick bamboo strips need to be cut into thin strips first, and then glued together with adhesive to form a three- or multi-layer sheet-like material. At this time, a bamboo cutting machine is needed to cut the bamboo strips.

[0003] In existing technologies, common bamboo cutting machines generally rely on the cooperation of internal blades and feeding devices to cut bamboo. Before cutting bamboo, the height of the blades needs to be set in advance to ensure the accuracy of the cutting. However, the thickness of bamboo slices is not the same. If the blade position is fixed, it cannot be guaranteed that the blade will cut from the middle of the bamboo slice every time. If the cutting position is not in the center of the bamboo slice, there is a risk of the bamboo slice breaking during the cutting process. Therefore, a single-layer two-slice bamboo cutting device is proposed to solve the above problems. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a bamboo single-layer two-piece cutting device, which aims to solve the problem in the prior art that "if the cutting blade cannot be aligned with the middle position of the bamboo piece during cutting, the bamboo piece is at risk of cracking during cutting".

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a bamboo single-layer two-piece cutting device, comprising: A machine platform, wherein a frame is mounted on the upper surface of the machine platform, a feeding assembly is provided on the inner wall of the frame, a cutting assembly is provided on the upper surface of the frame, and a trimming assembly is provided on the inner wall of the frame near the front end. The slitting assembly includes an extrusion frame that is slidably connected to the inner wall of the frame. A sliding frame one is fixedly connected to the upper surface of the extrusion frame, and a sliding frame three is fixedly connected to the top of the frame. A connecting plate is rotatably connected to the inner wall of the sliding frame three, and the connecting plate slides on the inner wall of the sliding frame one. A pull rod is slidably connected to the upper surface of the frame, and a sliding frame two is fixedly connected to the upper surface of the pull rod. A slitting blade is installed on the lower surface of the pull rod, and the outer wall of the connecting plate is slidably connected to the inner wall of the sliding frame two near the middle position.

[0006] As a further description of the above technical solution: The slitting assembly also includes a transmission rod, the lower surface of which is fixedly connected to the outer wall of the extrusion frame, the outer wall of which is slidably connected to the upper surface of the frame, and a closing plate is fixedly connected to the upper end of the transmission rod.

[0007] As a further description of the above technical solution: The lower surface of the sealing plate is elastically connected to the upper surface of the frame by a compression spring, and the lower surface of the compression frame is set to be arc-shaped.

[0008] As a further description of the above technical solution: The edge-cutting assembly includes a guide rod that passes through and is slidably connected to the left end of the frame, and an edge-cutting blade is fixedly connected to the right end of the guide rod.

[0009] As a further description of the above technical solution: The inner wall of the frame is elastically connected to the cutting blade by a cutting spring, and the front surface of the cutting blade is arc-shaped at one end near the center of the frame.

[0010] As a further description of the above technical solution: The feeding assembly includes a sliding plate, which is slidably connected to the inner wall of the frame. A sliding rod is fixedly connected through the inner wall of the frame. The sliding plate slides on the outer wall of the sliding rod. A feeding roller is rotatably connected to the inner wall of the sliding plate. The upper surface of the sliding plate is elastically connected to the inner wall of the frame through a return spring.

[0011] As a further description of the above technical solution: A feeding motor is mounted on the right surface of the frame, and the output shaft of the feeding motor is connected to the feeding roller via a coupling.

[0012] As a further description of the above technical solution: A longitudinal cutting blade is provided on the inner wall of the frame near the left end, a chip removal groove is provided on the upper surface of the machine base, and a feed frame is installed on the front surface of the frame.

[0013] This utility model has the following beneficial effects: 1. In this utility model, by setting an adjustable cutting component, when the bamboo strip comes into contact with the extrusion frame, the extrusion frame will be forced to move upward, which will cause the connecting plate to tilt. The connecting plate will pull the sliding frame two to drive the cutting blade to rise until it is aligned with the center of the bamboo strip. In this way, it can be ensured that the cutting is performed from the center of the bamboo strip, which can prevent the problem of cracking caused by incorrect cutting position.

[0014] 2. In this utility model, by setting up a cutting edge assembly, when the bamboo strip passes through the inside of the device, the bamboo strip will pass through the middle position of the two sets of cutting edge blades. The cutting edge blades will move towards the middle position under the action of the cutting edge spring. In this way, when the bamboo strip passes through, the cutting edge blades will grind its two sides, thus preventing its edges from being too sharp and injuring the operator.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a single-layer two-piece bamboo cutting device, comprising: a machine base 1, which is mainly used to support the overall device; a frame 2 is installed on the upper surface of the machine base 1; the frame 2 can provide support for the installation of other devices and protect other devices; a feeding component 3 is provided on the inner wall of the frame 2; a cutting component 4 for cutting bamboo strips is provided on the upper surface of the frame 2; and a cutting edge component 5 for polishing bamboo strips is provided on the inner wall of the frame 2 near the front end. The slitting assembly 4 includes a pressing frame 41 for pressing bamboo strips. The pressing frame 41 is slidably connected to the inner wall of the frame 2. When the bamboo strips come into contact with the pressing frame 41, the bamboo strips push the pressing frame 41 up, thus forcing the pressing frame 41 to rise a distance equal to the length of a bamboo strip. A sliding frame 42 is fixedly connected to the upper surface of the pressing frame 41. A sliding frame 44 for supporting a connecting plate 45 is fixedly connected to the top of the frame 2. A connecting plate 45 for transmitting power is rotatably connected to the inner wall of the sliding frame 44. The connecting plate 45 slides on the inner wall of the sliding frame 42. When the sliding frame 42 moves upward, it presses the connecting plate 45, forcing it to rotate upward. The upper surface of the frame 2... A pull rod 49 is slidably connected through the pull rod 49 to move the slitting blade 410. A sliding frame 43 for pulling the pull rod 49 is fixedly connected to the upper surface of the pull rod 49. The slitting blade 410 for cutting bamboo strips is installed on the lower surface of the pull rod 49. The outer wall of the connecting plate 45 is slidably connected to the inner wall of the sliding frame 43 near the middle position. Since the sliding frame 43 and the connecting plate 45 are connected to each other at the middle position, when the sliding frame 42 rises by the distance of one bamboo strip, the sliding frame 43 will only rise by half the distance of one bamboo strip. At the same time, the sliding frame 43 will drive the slitting blade 410 to rise by half the distance of one bamboo strip, so that the slitting blade 410 can be aligned with the center position of the bamboo strip.

[0019] Reference Figure 2 - Figure 4 The slitting assembly 4 also includes a transmission rod 48 for moving the extrusion frame 41. The lower surface of the transmission rod 48 is fixedly connected to the outer wall of the extrusion frame 41. The outer wall of the transmission rod 48 is slidably connected to the upper surface of the frame 2. When the transmission rod 48 moves up and down, it will drive the extrusion frame 41 to move up and down synchronously. The upper end of the transmission rod 48 is fixedly connected to a closing plate 46 for supporting the extrusion spring 47. The lower surface of the closing plate 46 is elastically connected to the upper surface of the frame 2 through the extrusion spring 47. The extrusion spring 47 will pull the closing plate 46 down at all times, so as to drive the transmission rod 48 to move down and reset. The lower surface of the extrusion frame 41 is set to be arc-shaped. The arc-shaped design makes it easier for the bamboo strips to lift the extrusion frame 41.

[0020] Reference Figure 1 - Figure 3 The edge-cutting assembly 5 includes a guide rod 51 for supporting the movement of the edge-cutting blade 53. The guide rod 51 passes through and is slidably connected to the left end of the frame 2. The guide rod 51 can move left and right on the inner wall of the frame 2. The right end of the guide rod 51 is fixedly connected to the edge-cutting blade 53 for polishing bamboo strips. The inner wall of the frame 2 and the edge-cutting blade 53 are elastically connected by an edge-cutting spring 52. The edge-cutting spring 52 will push the edge-cutting blade 53 to force it to fit against both sides of the bamboo strip through its own elastic deformation. The front surface of the edge-cutting blade 53 is set to be arc-shaped at one end near the center of the frame 2.

[0021] Reference Figure 1 - Figure 3 The feeding assembly 3 includes a sliding plate 36 for supporting the movement of the feeding roller 33. The sliding plate 36 is slidably connected to the inner wall of the frame 2 and can slide up and down on the inner wall of the frame 2. A slide rod 34 for guiding the movement of the sliding plate 36 is fixedly connected through the inner wall of the frame 2. The sliding plate 36 slides on the outer wall of the slide rod 34. The feeding roller 33 for pushing bamboo strips is rotatably connected to the inner wall of the sliding plate 36. The upper surface of the sliding plate 36 is elastically connected to the inner wall of the frame 2 by a return spring 35. The return spring 35 can push the sliding plate 36 downward at all times, thus driving the feeding roller. The outer wall of the bamboo strip is fitted with 33. A feeding motor 31 is installed on the right surface of the frame 2. The output shaft of the feeding motor 31 is connected to the feeding roller 33 through a coupling 32. The feeding roller 33 can be rotated by starting the feeding motor 31. A longitudinal cutter 7 for cutting bamboo strips is set on the inner wall of the frame 2 near the left end. When the bamboo strip passes through the splitting cutter 410, it will be cut into two pieces. When it passes through the longitudinal cutter 7 again, each bamboo strip will be cut into two pieces. A chip discharge groove 11 for discharging debris is set on the upper surface of the machine base 1. A feed frame 6 is installed on the front surface of the frame 2.

[0022] Working principle: The bamboo strips to be processed are placed into the device through the feeding frame 6. The feeding motor 31 is started, and its output shaft drives the feeding roller 33 to rotate via the coupling 32. Under the action of the return spring 35, the sliding plate 36 keeps the feeding roller 33 in contact with the outer wall of the bamboo strip, pushing the bamboo strip forward. When the bamboo strip passes the edge cutting assembly 5, under the action of the edge cutting spring 52, the edge cutting blade 53 is in contact with both sides of the bamboo strip to grind the edges. When the bamboo strip comes into contact with the extrusion frame 41 of the slitting assembly 4, the bamboo strip will push it up, and the extrusion frame 41 will drive the sliding frame 42 to rise, causing the connecting plate 45 to... The sliding frame 3 44 rotates upwards as a fulcrum, which in turn drives the slitting blade 410 to rise through the sliding frame 2 43 and the pull rod 49. When the sliding frame 1 42 rises one bamboo strip distance, the slitting blade 410 only rises half a bamboo strip distance to align with the center of the bamboo strip and complete the cutting, dividing the bamboo strip into upper and lower pieces. The cut bamboo strip continues to be conveyed and cut into two pieces again by the longitudinal cutter 7. The debris generated during the process is discharged through the chip discharge groove 11. After the bamboo strip passes through, the pressing frame 41 is reset under the action of the pressing spring 47, the transmission rod 48 and the closing plate 46 for the next operation.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
