Technical Field
[0001] This utility model belongs to the field of wood-plastic composite cutting, and in particular relates to a precision cutting device for wood-plastic composite materials. Background Technology
[0002] Wood-plastic composites are green and environmentally friendly composite materials made from lignocellulose, thermoplastic resins, and other additives. The traditional processing technology is basically granulation, extrusion, primary rough cutting, post-processing, and secondary precision cutting.
[0003] During the cutting process, the wood-plastic composite board is constantly being pushed forward. However, the existing primary cutting equipment cannot move synchronously with the wood-plastic composite board and can only perform a rough cut. This necessitates a secondary cut to ensure the accuracy of the board dimensions, resulting in a 1.5-3% waste of cutting head products during the secondary cut. Summary of the Invention
[0004] This invention provides a precision cutting device for wood-plastic composite materials, aiming to solve the problem that existing equipment cannot move synchronously with the wood-plastic board during the primary cutting stage, and can only perform coarse cutting of the wood-plastic board, which leads to the need for secondary cutting to ensure the accuracy of the board size and results in significant material loss.
[0005] This utility model is implemented as follows: a precision cutting device for wood-plastic composite materials, comprising:

[0008] The movable platform is equipped with a cutting device, and the metering crossbar is equipped with a stop bar unit. The wood-plastic composite board moves along the movable platform to the turning rack. When the front end of the wood-plastic composite board abuts against the stop bar unit, the movable platform moves synchronously with the wood-plastic composite board. After the movable platform moves to a specific position, the cutting device cuts the wood-plastic composite board located on the movable platform.
[0009] Preferably, the stop lever unit includes a cylinder, a cylinder stop lever, and a cylinder sliding seat, wherein the cylinder stop lever is disposed at the end of the cylinder, and the cylinder is mounted on the cylinder sliding seat.
[0010] Preferably, the base is provided with a photoelectric switch, and the movable platform is provided with a light-blocking strip. When the wood-plastic composite board pushes the movable platform to move, the light-blocking strip reaches the vicinity of the photoelectric switch and triggers the photoelectric switch signal, and the cutting device cuts the wood-plastic composite board located on the movable platform.
[0011] Preferably, the cylinder sliding seat slides on the metering crossbar.
[0012] Preferably, the steel frame is provided with pulleys, and the end of the measuring crossbar away from the movable platform slides on the pulleys.
[0013] Preferably, the turning frame is equipped with multiple sets of rotating rollers, and when the wood-plastic composite board reaches the turning frame, the wood-plastic composite board slides on the rotating rollers.
[0014] Compared with the prior art, the embodiments of this application have the following main advantages:
[0015] The precision cutting equipment for wood-plastic composite materials provided by this utility model achieves synchronous movement between the cutting equipment and the wood-plastic board to be cut during the cutting process.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0023] This utility model embodiment provides a precision cutting device for wood-plastic composite materials, such as... Figures 1-3 As shown, the precision cutting equipment for wood-plastic composite materials includes:
[0024] The steel frame 1 and the material turning rack 4 are fixed to the ground or other equipment plane. The material turning rack 4 is set on one side of the steel frame 1 and receives the wood-plastic composite board 7 from the upper section. The steel frame 1 is also provided with a base 10 at one end. The base 10 is set at the front end of the steel frame 1. The wood-plastic composite board 7 to be processed first passes over the base 10 and then reaches the material turning rack 4.
[0025] The positioning component includes a measuring crossbar 2, a support frame 8, and a movable platform 9. The support frame 8 is disposed at one end of the movable platform 9, and the measuring crossbar 2 is disposed on the side of the support frame 8 away from the movable platform 9. The movable platform 9 slides on the base 10, and the measuring crossbar 2 is provided with a stop bar unit.
[0026] During the normal forward movement of the wood-plastic composite board 7, the movable platform 9 will not move forward with the wood-plastic composite board 7. When the end of the wood-plastic composite board 7 abuts against the stop bar unit, the positioning component will move forward synchronously with the wood-plastic composite board 7. At this time, after the movable platform 9 passes through the designated area, it will trigger the cutting device 14 provided on the movable platform 9 to complete the cutting action. Since the cutting device 14 and the wood-plastic composite board 7 to be cut move synchronously during the cutting process, the cutting action is completed during the movement. Although the cutting action is completed during the movement, the cutting device 14 and the wood-plastic composite board 7 are actually in a relatively stationary state, allowing the cutting device 14 to perform a precise cutting operation on the wood-plastic composite board 7, achieving a precise cut in one step to avoid the need for secondary cutting processing, thereby reducing material waste. The cutting device 14 is an automated cutting machine in the prior art, which can actively perform the cutting action.
[0027] As a preferred embodiment of this example, Figure 3 As shown, the stop lever unit includes a cylinder 5, a cylinder stop lever 6, and a cylinder sliding seat 51. The cylinder stop lever 6 is located at the end of the cylinder 5. The cylinder 5 is mounted on the cylinder sliding seat 51. The cylinder sliding seat 51 slides on the measuring crossbar 2. The cylinder sliding seat 51 slides on the measuring crossbar 2 in a manner similar to a vernier caliper. The cylinder sliding seat 51 can precisely adjust the distance data.
[0028] In this embodiment, the measuring crossbar 2 and the movable platform 9 are an integrated structure. Therefore, when the wood-plastic composite board 7 touches the cylinder stop bar 6, although the wood-plastic composite board 7 will continue to move, the positioning component will also move synchronously with the wood-plastic composite board 7. The distance from the cutting device 14 to the stop bar unit on the movable platform 9 will not change as the wood-plastic composite board 7 moves. When the cutting device 14 is cutting, the cutting device 14 and the wood-plastic composite board 7 are in a relatively stationary state, thus avoiding the problem of speed difference affecting cutting accuracy.
[0029] In a preferred embodiment of this invention, the base 10 is provided with a photoelectric switch 11. When the movable platform 9 reaches a specific position, it reaches the vicinity of the photoelectric switch 11. The movable platform 9 is provided with a light-blocking strip 13. When the wood-plastic composite board 7 pushes the movable platform 9 to move, after the light-blocking strip 13 reaches the vicinity of the photoelectric switch 11 and triggers the photoelectric switch 11 signal, the cutting device 14 cuts the wood-plastic composite board 7 located on the movable platform 9.
[0030] The base 10 is also equipped with a pressure rod 12. The function of the pressure rod 12 is to apply pressure during the cutting process to make the wood-plastic board 7 fit against the movable platform 9. The pressure rod 12 is driven by a cylinder and can move up and down linearly.
[0031] Here, the base 10 is provided with a sliding groove 1001, and the movable platform 9 is provided with a guide rod 901 and a reset stop rod 902. The guide rod 901 is disposed on both sides of the reset stop rod 902, and the U-shaped rod formed by the guide rod 901 and the reset stop rod 902 slides in the sliding groove 1001.
[0032] The sliding groove 1001 is also equipped with a cylinder push rod 1002. After the movable platform 9 completes the cutting action, the cylinder push rod 1002 moves. The end of the cylinder push rod 1002 contacts and connects with the reset stop rod 902, so that the movable platform 9 moves in the opposite direction to the forward direction of the wood-plastic composite board 7, waiting for the next contact between the wood-plastic composite board 7 and the cylinder stop rod 6. After the movable platform 9 returns to the initial position, the cylinder push rod 1002 actively retracts to avoid affecting the synchronous movement of the movable platform 9 along with the wood-plastic composite board 7.
[0033] The movable platform 9 adopts a smooth surface structure. Before the wood-plastic composite board 7 comes into contact with the cylinder stop rod 6, the movable platform 9 will not move with the wood-plastic composite board 7. When the movable platform 9 moves with the wood-plastic composite board 7, the U-shaped rod will move synchronously along the sliding groove 1001.
[0034] In this embodiment, the photoelectric switch 11 is a prior art technology and is mainly used as a trigger condition. Here, the light-blocking strip 13 blocks the light propagation of the photoelectric switch 11 to achieve the cutting purpose. The precondition for the activation of the photoelectric switch 11 is that the cylinder push rod 1002 completes the reset of the movable platform 9. When the movable platform 9 passes through the photoelectric switch 11 in the reverse direction, the photoelectric switch 11 will not be triggered.
[0035] In a further preferred embodiment of this utility model, the steel frame 1 is provided with a pulley 3, and the end of the measuring crossbar 2 away from the movable platform 9 slides on the pulley 3; the pulley 3 mainly supports the measuring crossbar 2 to prevent the measuring crossbar 2 from shifting during movement and affecting the processing accuracy;
[0036] In a preferred embodiment of this invention, the material turning rack 4 is provided with multiple sets of rotating rollers. When the wood-plastic composite board 7 reaches the material turning rack 4, the wood-plastic composite board 7 slides on the rotating rollers.
[0037] It should be noted that, for the sake of simplicity, the foregoing embodiments are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to the present invention.
[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art can still combine, add, delete, or otherwise adjust the features of the various embodiments of this utility model according to the circumstances without conflict or creative effort, thereby obtaining different technical solutions that do not fundamentally depart from the concept of this utility model.
