Technical Field
[0001] This utility model relates to the field of plywood production and processing technology, and in particular to a plywood edge trimming device. Background Technology
[0002] Plywood, a commonly used engineered wood product, is widely used in furniture manufacturing, building decoration, and other fields. Its production process typically includes veneer rotary cutting, drying, gluing, assembly, and hot pressing. After hot pressing, plywood often has burrs and uneven edges, and due to cutting errors or veneer splicing, edge dimensional accuracy is difficult to guarantee. Therefore, trimming the edges of plywood is a necessary step to ensure its quality and applicability, directly affecting subsequent processing and use.
[0003] However, current plywood edge trimming techniques still have significant shortcomings. On the one hand, there is a lack of reliable and efficient fixing methods for plywood during trimming. Due to the diverse sizes and specifications of the plywood, traditional clamps are difficult to adapt to different sizes, resulting in poor fixing and easy displacement of the plywood during trimming. On the other hand, existing trimming equipment cannot guarantee the flatness and perpendicularity of the edges. Factors such as tool wear and unstable feed speed result in uneven edges on the trimmed plywood, failing to meet the requirements of high-precision production and affecting product quality and processing efficiency.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0019] The plywood edge trimming device of this utility model embodiment will now be described with reference to the accompanying drawings.
[0020] like Figures 1-3 As shown, the plywood edge trimming device provided in this embodiment of the present invention includes a trimming table 2, a trimming drive mechanism 3, and a trimming cutter head 4. The trimming drive mechanism 3 is disposed on the trimming table 2, the trimming cutter head 4 is disposed on the trimming drive mechanism 3, and a support 1 is disposed at the bottom of the trimming table 2.
[0021] The trimming drive mechanism 3 includes a transverse guide rail 31, a main arm 32, and a trimming motor 35. The transverse guide rail 31 is mounted on the trimming table 2, the main arm 32 is mounted on the transverse guide rail 31, and the trimming motor 35 is mounted at the end of the main arm 32. The output shaft of the trimming motor 35 is connected to the trimming cutter head 4.
[0022] The dressing table 2 is equipped with a clamping mechanism 5, including a clamping seat 51, a clamping cylinder 53 and a clamping plate 52. The clamping seat 51 is located below the dressing cutter head 4, the clamping cylinder 53 is located on the clamping seat 51, and the clamping plate 52 is located behind the clamping seat 51.
[0023] Specifically, when using the plywood edge trimming device of this application, the plywood 6 is first placed in the clamping seat 51. After the plywood 6 is positioned correctly, the clamping cylinder 53 drives the clamping plate 531 to move downward, fixing the front side of the plywood 6. The clamping plate 52 fixes the rear side of the plywood 6, effectively positioning the plywood 6 and preventing it from shifting during edge trimming. Subsequently, the transverse guide rail 31 drives the main arm 32 to move, which in turn drives the trimming cutter head 4 to move horizontally. During the transverse movement of the main arm 32, the trimming motor 35 drives the trimming cutter head 4 to rotate, thereby neatly trimming and polishing the edge of the plywood 6.
[0024] In one embodiment of this utility model, such as Figure 2 As shown, a telescopic arm 321 is provided at the end of the main arm 32, and a vertical position adjustment assembly 33 is provided at the end of the telescopic arm 321, including a fixed seat 332, a sliding seat 334, and a lead screw 333. The fixed seat 332 is fixedly connected to the end of the telescopic arm 321. The sliding seat 334 is vertically slidably mounted on the fixed seat 332. The lead screw 333 is threaded through the sliding seat 334. An adjustment motor 331 is mounted on the fixed seat 332, and the power shaft of the adjustment motor 331 is connected to the lead screw 333. A trimming motor 35 is mounted on the sliding seat 334, and the power shaft of the trimming motor 35 is connected to the trimming cutter head 4. The trimming motor 35 is mounted on the sliding seat 334, and the trimming motor 35 and the trimming cutter head 4 are detachable.
[0025] Specifically, according to the different thickness requirements of the plywood 6, during the operation of the trimming head 4, the motor 331 drives the lead screw 333 to rotate, the lead screw 333 engages with the sliding seat 334, and drives the sliding seat 334 to adjust its up and down position, thereby driving the trimming head 4 to adjust its up and down trimming position, and thus adjusting the position of the trimming head 4 according to the different thicknesses of the plywood 6 edge.
[0026] In one embodiment of this utility model, such as Figure 2 As shown, the trimming table 2 is equipped with an arm support slide 34, and the main arm 32 is slidably connected to the arm support slide 34. The transverse guide rail 31 is an electric guide rail. The arm support slide 34 provides sliding support to the end of the main arm 32 during movement, reducing play and sway at the end of the main arm 32.
[0027] In one embodiment of this utility model, such as Figure 2 As shown, a clamping plate 531 is provided at the bottom of the clamping cylinder 53. The clamping plate 531 is parallel to the clamping seat 51. A support 521 is provided on the trimming table 2. The clamping plate 52 is elastically hinged to the support 521. Multiple guide wheels 522 are provided on the support 521. An inclined inlet is provided at the entry end of the clamping plate 52.
[0028] Specifically, since the clamping plate 52 is elastically hinged to the support 521, the clamping plate 531 facilitates the entry of the plywood 6 into its bottom through the guide wheel 522, thereby clamping the rear end of the plywood 6. In conjunction with the clamping plate 531, the front end of the plywood 6 is clamped, so that both the front and rear sides of the plywood 6 can be fixed, preventing the plywood 6 from shifting during the edge trimming process.
[0029] To clearly illustrate the above embodiments, refer to Figures 1-3The specific working principle of the plywood edge trimming device of this utility model is as follows: When using the plywood edge trimming device of this application, the plywood 6 is first placed in the clamping seat 51. After the plywood 6 is positioned correctly, the clamping cylinder 53 drives the clamping plate 531 to move down and fix the front side of the plywood 6. During the process of the plywood 6 moving backward and pressing the clamping plate 52, the plywood 6 enters through the inclined inlet at its front end and enters the bottom of the clamping plate 52 through the guide wheel 522. At this time, the clamping plate 52 presses down and fixes the rear side of the plywood 6, so that the plywood 6 is effectively positioned and prevents the plywood 6 from shifting during edge trimming.
[0030] Subsequently, according to the different thickness requirements of the plywood 6, the motor 331 drives the lead screw 333 to rotate, which in turn drives the sliding seat 334 to adjust its up and down position, thereby driving the trimming head 4 to adjust its up and down trimming position. The position of the trimming head 4 is then adjusted according to the different thicknesses of the plywood 6 edges. Then, the transverse guide rail 31 drives the main arm 32 to move, which in turn drives the trimming head 4 to move horizontally. During the transverse movement of the main arm 32, the trimming motor 35 drives the trimming head 4 to rotate, thus neatly trimming and polishing the edges of the plywood 6.
[0031] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
