Description

Technical Field

[0001] This utility model relates to the field of hot pressing and veneer technology for bamboo furniture boards, specifically a hot pressing and veneer machine with a smoothing mechanism. Background Technology

[0002] The hot press veneer machine for bamboo furniture boards is a specialized piece of equipment used in the woodworking and furniture manufacturing industries. It is mainly used to firmly bond decorative veneers (such as thin wood veneers, decorative paper, or composite materials) to the surface of boards. This type of machine uses hot press technology to tightly bond the veneer material to the board through heating and pressure, forming a beautiful and durable surface effect.

[0003] In existing technologies, when hot-pressing and veneering is performed on reconstituted bamboo furniture boards, the boards at the hot-pressing position are prone to shifting, which affects the quality of the pressing process.

[0004] To overcome the above shortcomings, a Chinese patent (publication number CN217476164U) discloses a hot-press veneer machine for making wooden doors, including a base, a pressure table, and a veneer holder. The veneer holder is hinged to the upper end of the base via a damping hinge, and the pressure table is located inside the upper end of the base. Through the cooperation of a two-way screw, pulley one, and pulley two, the two clamping plates are moved closer or further apart, making it convenient for users to clamp wooden door panels of different sizes. During the veneer process, it can prevent the wooden door panels from sliding and affecting the veneer effect. Through the combination of a threaded rod, a sliding block, a cleaning roller, a chip removal hose, a suction fan, a chip removal pipe, and a chip collection box, it can clean the surface debris of the wooden door panels when the threaded rod drives the sliding block to move left and right, which can solve the problem of residual debris on the surface of wooden door panels, which affects the veneer quality after veneer application.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, when hot-pressing the reconstituted bamboo furniture board, the veneer material is prone to wrinkles due to carelessness of the workers. As the reconstituted bamboo furniture board is hot-pressed, the wrinkled veneer material can easily cause unevenness on the surface of the reconstituted bamboo furniture board, affecting the quality of the final product. Utility Model Content

[0006] The purpose of this utility model is to provide a hot press veneer machine with a smoothing mechanism to solve the problem mentioned in the background art that when hot pressing veneer onto bamboo furniture boards, the veneer material is prone to wrinkles due to the carelessness of the workers. The wrinkled veneer material, when hot pressed onto the bamboo furniture boards, easily makes the surface of the bamboo furniture boards uneven, affecting the quality of the final product.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hot press skin applicator with a smoothing mechanism, comprising a frame and a hot press platform mounted on the upper end of the frame. A hot presser is mounted on the upper end of the frame via a hydraulic rod, and the lower end of the hot presser corresponds to the hot press platform. An adjusting plate is rotatably provided on the lower end of the hot presser, and a smoothing mechanism is provided on the outer side of the adjusting plate. A protective cover is fitted on the outer side of the hot presser, and an auxiliary protection mechanism is provided inside the protective cover.

[0008] Furthermore, a bidirectional threaded rod is rotatably mounted on the lower end of the frame, and the threads at the left and right ends of the bidirectional threaded rod are opposite. A motor is provided at the left end of the bidirectional threaded rod, and the upper end of the motor is mounted on the left side of the frame.

[0009] Furthermore, a positioning clamp is threaded onto the surface of the bidirectional threaded rod, and a guide rod is threaded through the middle of the positioning clamp. The left and right sides of the guide rod are fixedly installed inside the frame, and the inner side of the positioning clamp corresponds to the hot pressing platform.

[0010] Furthermore, the smoothing mechanism is equipped with a smoothing roller, which is rotatably mounted on the lower end of the adjusting plate, and the adjusting plate and the smoothing roller are arranged around the bottom of the hot press.

[0011] Furthermore, a torsion spring is sleeved on the outer side of the adjusting plate, and the outer side of the torsion spring is fixedly installed on the outer side of the hot press.

[0012] Furthermore, the auxiliary protection mechanism is provided with a support plate, and the lower end of the support plate is fixedly installed on the upper end of the hot press. The support plate is L-shaped, and the middle end of the support plate passes through the protective cover.

[0013] Furthermore, a damper is installed through the outer side of the support plate, and the lower end of the damper is fixedly installed on the upper end of the protective cover. A return spring is provided between the protective cover and the support plate. Openings are provided on the left and right sides of the protective cover, and the openings correspond to the positioning clamps.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. As the hot press descends to hot press the bamboo furniture board and veneer material on the hot press platform surface, the smoothing roller at the lower end of the adjusting plate contacts the material first. As the hot press continues to descend, the adjusting plate rotates around the hot press to stretch the torsion spring, and the smoothing roller rolls to smooth the material, further improving the quality of hot-pressed veneer.

[0016] Furthermore, during the hot-press veneer application process, the hot-press veneer machine places the bamboo furniture board and the veneer material on the hot-press platform surface. The motor's activation drives a bidirectional threaded rod to rotate, clamping the bamboo furniture board along the inner side of the frame. This secures the bamboo furniture board during the hot-press process via hydraulic rods, preventing material displacement and defects during veneer application, thus improving the overall quality of the hot-press veneer application.

[0017] 2. When the hot press descends to perform hot pressing and bonding, the protective cover first contacts the surface of the frame. At this time, the descent of the protective cover covers the hot pressing platform and the material at the top. As the hot press descends, it drives the support plate. The support plate passes through the protective cover and squeezes the return spring. The spring force of the return spring applies pressure to the protective cover, making the protective cover fit tightly against the frame, achieving the protective effect and preventing workers from being burned by contact with the hot press.

[0025] 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.

[0026] Example 1: As Figures 1-5 The technical solution shown is a hot press skin-applying machine with a smoothing mechanism. To address the problem of material wrinkling during hot pressing, the machine discloses: a frame 1 and a hot press platform 2 mounted on the upper end of the frame 1. A hot presser 4 is mounted on the upper end of the frame 1 via a hydraulic rod 3, and the lower end of the hot presser 4 corresponds to the hot press platform 2. An adjusting plate 8 is rotatably mounted on the lower end of the hot presser 4, and a smoothing mechanism is provided on the outer side of the adjusting plate 8. A bidirectional threaded rod 5 is rotatably mounted on the lower end of the frame 1, with opposite threads on the left and right ends of the bidirectional threaded rod 5. A motor is located on the left end of the bidirectional threaded rod 5. The upper end of the motor is installed on the left side of the frame 1. The surface of the bidirectional threaded rod 5 is threaded with a positioning clamp 6, and a guide rod 7 is installed through the middle of the positioning clamp 6. The left and right sides of the guide rod 7 are fixedly installed inside the frame 1. The inner side of the positioning clamp 6 corresponds to the hot press platform 2. The smoothing mechanism is provided with a smoothing roller 10, and the smoothing roller 10 is rotatably installed at the lower end of the adjusting plate 8. The adjusting plate 8 and the smoothing roller 10 are arranged around the bottom of the hot press 4. A torsion spring 9 is sleeved on the outside of the adjusting plate 8, and the outside of the torsion spring 9 is fixedly installed on the outside of the hot press 4.

[0027] When performing hot-press veneer application, the hot-pressed bamboo furniture board and the veneer material are placed correspondingly on the surface of the hot-pressing platform 2, such as... Figure 3 As shown, the motor starts, driving the bidirectional threaded rod 5 to rotate. When the bidirectional threaded rod 5 rotates, it drives the positioning clamp 6, which is threaded to the surface. Under the limit of the guide rod 7, the positioning clamp 6 clamps the reconstituted bamboo furniture board on the surface of the hot pressing platform 2 along the inner side of the frame 1. This allows the reconstituted bamboo furniture board to be fixed during hot pressing by the hot presser 4 via the hydraulic rod 3, preventing material displacement during hot pressing and veneer application, thus improving the quality of the hot pressing and veneer application. Figure 4 and Figure 5 As shown, when the hot press 4 descends to hot press the bamboo furniture board and veneer material on the surface of the hot press platform 2, the smoothing roller 10 at the lower end of the adjusting plate 8 contacts the material first. As the hot press 4 continues to descend, the adjusting plate 8 rotates around the hot press 4 to stretch the torsion spring 9, and the smoothing roller 10 rolls to smooth the material, further improving the quality of the hot-pressed veneer.

[0028] Example 2: Figures 1-6The technical solution shown, based on Embodiment 1, discloses the following to address the issue of user injury during operation: a protective cover 13 is fitted around the outside of the hot press 4, and an auxiliary protection mechanism is provided inside the protective cover 13. The auxiliary protection mechanism includes a support plate 11, with the lower end of the support plate 11 fixedly installed on the upper end of the hot press 4. The support plate 11 is L-shaped, and its middle end passes through the protective cover 13. A damper 14 is installed through the outside of the support plate 11, with the lower end of the damper 14 fixedly installed on the upper end of the protective cover 13. A return spring 12 is provided between the protective cover 13 and the support plate 11. Openings are provided on the left and right sides of the protective cover 13, and these openings correspond to the positioning clamp 6.

[0029] When the hot press 4 descends to perform hot pressing and bonding, the protective cover 13 first contacts the surface of the frame 1. At this time, the descent of the protective cover 13 covers the hot press platform 2 and the material above it. Figure 5 As shown, as the hot press 4 descends, it drives the support plate 11. The support plate 11 passes through the protective cover 13 and compresses the return spring 12. The return spring 12 applies pressure to the protective cover 13 through its elastic force. Figure 6 As shown, the damper 14 prevents the return spring 12 from reciprocating. Under the pressure of the return spring 12, the protective cover 13 fits tightly against the frame 1, achieving a protective effect and preventing workers from being burned by contact with the hot press 4.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
