Description

Technical Field

[0001] This utility model relates to the technical field of plywood production equipment, and in particular to a plywood trimming device. Background Technology

[0002] Plywood is a large sheet material made by gluing and hot-pressing three or more layers of one-millimeter-thick veneers or thin sheets together, with the grain direction of adjacent veneers arranged at 90-degree angles (usually using an odd number of layers). After pressing, plywood needs to be trimmed to ensure its uniformity; however, existing trimming devices are not stable and can easily cause the trimming saw blade to jam due to loose plywood. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a plywood trimming device with good trimming effect.

[0006] Furthermore, a controller is fixedly connected to the side wall of the support frame; the controller is electrically connected to the drive unit, the trimming unit, and the electric cylinder respectively.

[0007] Furthermore, the drive unit includes a first motor, a lead screw with one end fixedly connected to the output end of the motor, and a connecting seat rotatably connected to the other end of the lead screw.

[0008] Furthermore, the trimming part includes a housing, a second motor fixed inside the housing, and trimming saw blades fixed to the output end of the motor and located in the material drop holes on both sides of the platform.

[0009] Furthermore, the pressure plate is a rectangular pressure plate arranged along the length of the platform.

[0010] Furthermore, rubber blocks are evenly arranged at the lower end of the pressure plate.

[0011] The beneficial effects of this utility model are:

[0012] (1) By setting up an electric cylinder and a pressure plate, the controller can control the electric cylinder to stretch so that the pressure plate can effectively fix the plywood, preventing it from loosening during trimming and causing the trimming saw blade to jam, thus ensuring the plywood edges are flat and consistent.

[0013] (2) By setting rubber blocks, the rubber blocks have a certain deformation, which can prevent the pressure plate from excessively squeezing the plywood and causing damage. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Reference Figure 1-3 As shown, a plywood trimming device includes a platform 1, a drive unit 2 symmetrically fixed to both sides of the platform 1 along its length, a trimming unit 3 movable relative to the length of the platform 1 and threadedly connected to the drive unit 2, a support frame 4 fixed to both sides of the middle part of the platform 1, an electric cylinder 5 fixed to the support frame 4, and a pressure plate 6 fixed to the output end of the electric cylinder 5 and located at the lower end of the support frame 4.

[0022] It should be noted that platform 1 can be used to place untrimmed plywood and also to support other components; drive unit 2 is used to move trimming unit 3, and drive unit 2 adopts synchronous movement to ensure the consistency of repair on both sides of the plywood; trimming unit 3 can repair the edges of plywood; support frame 4 can facilitate the placement and support of electric cylinder 5 and pressure plate 6; electric cylinder 5 can drive pressure plate 6 to move, thereby squeezing and fixing the plywood to be trimmed.

[0023] To facilitate the coordinated operation of the drive unit 2, the trimming unit 3, and the electric cylinder 5, a controller 7 is fixedly connected to the side wall of the support frame 4; the controller 7 is electrically connected to the drive unit 2, the trimming unit 3, and the electric cylinder 5 respectively. The controller 7 is a commercially available product, and those skilled in the art can select it according to actual needs.

[0024] Specifically, the drive unit 2 includes a first motor 21, a lead screw 22 with one end fixedly connected to the output end of the motor, and a connecting seat 23 rotatably connected to the other end of the lead screw 22. The first motor 21 can drive the lead screw 22 to move, thereby driving the trimming part 3 to move; the connecting seat 23 is used to facilitate the rotation of the lead screw 22.

[0025] Specifically, the trimming part 3 includes a housing 31, a second motor 32 fixed inside the housing 31, and trimming saw blades 33 fixed to the output end of the motor and located in the material drop holes 11 on both sides of the platform 1. The housing 31 can be easily threadedly connected to the lead screw 22 and can be close to the platform 1 and can also move relative to the platform 1; the second motor 32 is used to control the rotation of the trimming saw blades 33 to repair the edges of the plywood.

[0026] To improve the fixing effect of the pressure plate 6 on the plywood, the pressure plate 6 is a rectangular pressure plate arranged along the length of the platform 1. Rubber blocks 61 are evenly arranged at the lower end of the pressure plate 6. The rubber blocks 61 have a certain degree of deformation, which can prevent the pressure plate 6 from excessively squeezing the plywood and causing damage.

[0027] The working principle of this utility model:

[0028] The plywood is placed into a predetermined position on platform 1 from the side away from the first motor 21. By setting up an electric cylinder 5 and a pressure plate 6, the controller 7 can control the electric cylinder 5 to stretch, so that the pressure plate 6 can effectively fix the plywood, preventing it from loosening during trimming and causing the trimming saw blade 33 to jam, thus ensuring the flatness and uniformity of the plywood edges. By setting up a drive unit 2, the first motor 21 on the drive unit 2 can drive the lead screw 22 to move, thereby driving the trimming unit 3 to move. By setting up a trimming unit 3, the second motor 32 on the trimming unit 3 can drive the trimming saw blade 33 to rotate, thereby trimming the plywood after it has been stabilized by the electric cylinder 5 and the pressure plate 6. By setting up a rubber block 61, the rubber block 61 has a certain deformation, which can prevent the pressure plate 6 from excessively squeezing the plywood and causing damage.

[0029] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
