Description

Technical Field

[0001] The utility model relates to the field of composite multi-layer board processing, and specifically relates to a slitting device for an environment-friendly composite multi-layer board. Background Art

[0002] A multi-layer board is a board-shaped material composed of three or more layers obtained by slicing a log into veneers or planing a wooden square into thin woods and then gluing them with an adhesive. Usually, an odd number of veneers are used, and the fiber directions of adjacent veneers are glued perpendicular to each other. The manufacturing method of the multi-layer board generally starts with the inner layer pattern, and then a single-sided or double-sided substrate is made by the printing and etching method and incorporated into the specified interlayer, and then heated, pressed and bonded. As for the subsequent drilling, it is the same as the through-hole plating method for double-sided boards. Common types of plywood include three-ply boards, five-ply boards, etc. Plywood can improve the utilization rate of wood and is a main way to save wood. However, the existing plywood and multi-layer boards still have poor flatness, and deformation, warping and cracking are very serious. They can only be used as building templates, packing boxes, etc. It is necessary to perform slitting work on the surface of the multi-layer board to create a buffer area when it deforms.

[0003] According to the disclosed patent CN212266082U, a slitting device for an environment-friendly composite multi-layer board includes a support plate. Sliding blocks are fixed at both ends of the support plate. A slitting mechanism is fixed at the top of the middle part of the support plate. Support columns are slidably connected to both sides of the sliding blocks. The bottom ends of the support columns are fixed to the base by welding. A hydraulic rod is fixed at the top of the center of the base. The slitting mechanism includes a motor, a first rotating rod, a housing, a second rotating rod, a slitting knife and a protective shell. The bottom end of the motor is fixed to the first rotating rod. The housing is fixed to the bottom of the middle part of the support plate. In the process of implementing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. Through a series of improvements, the device can effectively perform slitting work on the surface of the multi-layer board to create a buffer area when it deforms, and can ensure that the depth of the slit is consistent, and can also perform slitting work with high accuracy, greatly improving the work efficiency and reducing the work burden of the staff. During use, since the slitting positions of multi-layer boards of different sizes are different, and the distance between the existing two slitting knives is fixed, it is not convenient to slit multi-layer boards of different sizes. Moreover, when the multi-layer board is conveyed by a conveyor, it is easy to shift, which affects the quality of the slitting of the multi-layer board. Therefore, a new technical solution needs to be designed to solve this problem. Content of the Utility Model

Specific embodiments

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0022] Embodiment 1: A slitting device for an environment-friendly composite multi-layer board, see Figures 1 to 4, including a conveyor 1. Vertical plates 3 are fixedly connected to both sides of the top of the conveyor 1. A connecting plate 36 is arranged between the two vertical plates 3. A box body 4 is installed at the bottom of the connecting plate 36. A connecting shaft 47 is rotatably connected between the two sides of the inner cavity of the box body 4. A gear column 46 is fixedly connected to the outer side of the connecting shaft 47. Driven gears 48 are fixedly connected to the outer sides of the connecting shaft 47 on both sides of the gear column 46. A double-shaft motor 44 is installed at the top of the inner cavity of the box body 4 through a pull rod. Driving gears 45 are fixedly connected to the driving ends at both ends of the double-shaft motor 44. The two driving gears 45 are respectively meshed with the two driven gears 48. Driving shafts 410 rotatably penetrate through both sides of the box body 4. Cutting knives 43 are installed at one ends of the outer sides of the two driving shafts 410. Passive gears 49 are fixedly connected to the outer sides of the two driving shafts 410. The two passive gears 49 are both meshed with the gear column 46; an adjustment groove 5 is opened at the bottom end of the inner cavity of the box body 4. A bidirectional lead screw 51 is rotatably connected between the two sides of the inner cavity of the adjustment groove 5. Two adjustment blocks 52 are slidably connected in the adjustment groove 5, and the two adjustment blocks 52 are respectively thread sleeved on both sides of the outer part of the bidirectional lead screw 51. Installation plates 411 are fixedly connected to the tops of the two adjustment blocks 52. Circular grooves 412 are opened at one ends of the two installation plates 411 close to the driving shafts 410. Bearings 413 are installed in the two circular grooves 412. The inner rings of the two bearings 413 are respectively fixedly connected to the outer sides of the two driving shafts 410. Both ends of the bidirectional lead screw 51 penetrate through and are located outside the box body 4. Handwheels 53 are fixedly connected to the bidirectional lead screws 51 on the outer sides of both ends of the box body 4. By holding the handwheels 53 and rotating them, the bidirectional lead screw 51 is driven to rotate, so as to cooperate with the installation plates 411 to push the distance of the driving shafts 410 outside the box body 4, so as to adjust the distance between the two cutting knives 43. At the same time, the passive gears 49 are always meshed with the gear column 46. By starting the double-shaft motor 44 to drive the two driving gears 45 to rotate, the gear column 46 is driven through the driven gears 48. Furthermore, the gear column 46 can drive the two passive gears 49 to rotate at the same time. With one end of the driving shaft 410 rotatably connected to the installation plate 411 through the bearing 413, the two cutting knives 43 with adjusted distance between them can be driven to rotate at the same time to cut slits in the multilayer board, which is convenient for cutting slits with different pitches on multilayer boards of different sizes.

[0023] Specifically, refer to Figure 1, T-shaped rods 2 penetrate through both sides at both ends of the conveyor 1. A fixing plate 23 is fixedly connected between two T-shaped rods 2 on the same side. A driving rod 22 penetrates through the conveyor 1 between two T-shaped rods 2 on the same side, and the driving rod 22 is threadedly connected to the conveyor 1. One end of the driving rod 22 is rotatably connected to the fixing plate 23. A spring 21 is sleeved on the T-shaped rod 2 outside the conveyor 1, and both ends of the spring 21 are connected to the T-shaped rod 2 and the conveyor 1 respectively. A plurality of limiting wheels 24 are rotatably connected to the bottom of the fixing plate 23, and the limiting wheels 24 do not contact the conveyor belt of the conveyor 1. When the multi-layer board is placed on the conveyor 1 for conveying and cutting, by turning the driving rod 22 to rotate and push the fixing plate 23 to move so that the limiting wheels 24 contact both sides of the multi-layer board, the multi-layer board being conveyed can be limited in movement, thereby avoiding the multi-layer board shifting during cutting and affecting the quality of the cut. When limiting the multi-layer board, the spring 21 is in a compressed state and has elasticity. Thus, when turning the driving rod 22 to reset the fixing plate 23, the elasticity of the spring 21 can assist the fixing plate 23 in resetting.

[0024] Further, referring to Figure 1 , on the relative ends of two vertical plates 3, chutes 31 are respectively opened. Sliders 35 are slidably connected in both chutes 31. A screw rod 33 is rotatably connected between the upper and lower sides of the inner cavity of one of the chutes 31, and the slider 35 is threadedly sleeved on the outside of the screw rod 33. A connecting plate 36 is fixedly connected between the two sliders 35. A servo motor 32 is installed on the top of one of the vertical plates 3, and the driving end of the servo motor 32 is connected to the screw rod 33. By starting the servo motor 32 to drive the screw rod 33 to rotate, since the slider 35 moves in a guiding manner in the chute 31, the height of the box body 4 can be adjusted, and thus the cutting depth of the cutting knife 43 for the multi-layer board can be adjusted.

[0025] It should be noted that, referring to Figure 1 , a heat dissipation hole 41 is opened at one end of the box body 4, and a filter screen is arranged in the heat dissipation hole 41. Through the heat dissipation hole 41, the heat generated when the double-shaft motor 44 in the box body 4 works can be discharged from the box body 4.

[0026] It should be noted that, referring to Figure 1 , arc-shaped protective shells 42 are fixedly connected to both ends of the box body 4, and the two arc-shaped protective shells 42 are respectively placed outside the two cutting knives 43. Through the arrangement of the arc-shaped protective shells 42, not only can the harm caused by the cutting knife 43 to personnel be effectively prevented, but also the flying of debris generated by cutting can be effectively prevented.

[0027] It should be noted that, referring to Figure 1 , a scale line 34 is arranged on the vertical plate 3 on one side of the chute 31. Through the arrangement of the scale line 34, the height of the cutting knife 43 can be accurately adjusted, and thus the accuracy of cutting the depth of the multi-layer board can be improved.

[0028] In addition, the components designed by the present utility model are all common standard components or components known to those skilled in the art. Their structures and principles can all be learned by those skilled in the art through technical manuals or through conventional experimental methods.
