Description

Technical Field

[0001] This utility model relates to the field of melamine paper processing technology, and in particular to a melamine paper alignment mechanism. Background Technology

[0002] Melamine paper is a specially treated decorative paper. It uses high-quality wood pulp paper as the base material, and the surface is impregnated with melamine resin adhesive. After being cured under high temperature and pressure, it forms a wear-resistant, scratch-resistant, and corrosion-resistant decorative layer.

[0003] There are various surface treatment methods for decorative panels, including PVC film lamination, UV paint spraying, heat transfer printing, and melamine paper lamination. Among them, melamine paper lamination is a common process, which uses high temperature and high pressure to tightly bond melamine paper to the substrate (such as MDF or particleboard) to form a sturdy and durable finish.

[0004] Currently, due to the lack of an automatic alignment mechanism before the decorative boards and melamine paper are laminated, manual trimming of the uneven edges of the paper and boards is still required after the laminated boards are laminated. This not only increases labor costs but also wastes materials, seriously affecting production efficiency and increasing material costs. Therefore, a melamine paper alignment mechanism is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a melamine paper alignment mechanism, which aims to improve the problem mentioned in the prior art that "decorative boards and melamine paper cannot be automatically aligned before pressing".

Detailed Implementation

[0032] 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.

[0033] Reference Figure 1 - Figure 3 One embodiment of this utility model is a melamine paper alignment mechanism, including a machine base 1. A bracket 2 is fixedly installed on the top of the machine base 1. A hydraulic cylinder 5 is fixedly installed through and on the top of the bracket 2. A pressure plate 6 is fixedly installed on the piston end of the hydraulic cylinder 5. Activating the hydraulic cylinder 5 drives the pressure plate 6 to move downward to press the decorative board and melamine paper together. The machine base 1 is internally equipped with an alignment mechanism 3 and an adjustment mechanism 4.

[0034] with reference to Figure 2 , Figure 3 and Figure 5 , the aligning mechanism 3 includes a motor 31. The motor 31 may be a servo motor, and the forward and reverse rotation of the motor 31 is controlled by a servo controller. The motor 31 is fixedly mounted on the side wall of the machine base 1, the output end of the motor 31 is fixedly mounted with a lead screw 32, and starting the motor 31 can drive the lead screw 32 to rotate. The end of the lead screw 32 away from the motor 31 penetrates through the machine base 1 and is fixedly mounted with an L-shaped rod 33, and the lead screw 32 is rotatably connected at the penetration position with the machine base 1. The inner wall of the machine base 1 is slidably connected with a push plate 34, the push plate 34 is of a "C"-shaped structure, and the top end of the push plate 34 extends above the machine base 1. When the push plate 34 contacts the decorative plate and the melamine paper during the sliding process, it will perform preliminary alignment on them, and at the same time, the push plate 34 will push the decorative plate and the melamine paper to the lower part of the pressing plate 6, so as to press the decorative plate and the melamine paper. The push plate 34 is in threaded connection with the lead screw 32, and the rotation of the lead screw 32 can drive the push plate 34 in threaded connection therewith to slide on the inner wall of the machine base 1.

[0035] with reference to Figure 3 to Figure 5 , the inner wall of the machine base 1 is slidably connected with a hollow rod 35, the outer wall of the L-shaped rod 33 fits against the inner wall of the hollow rod 35, and the rotation of the lead screw 32, in cooperation with the L-shaped rod 33, can drive the hollow rod 35 to slide up and down reciprocally on the inner wall of the machine base 1. The inner wall of the bracket 2 penetrates and is slidably connected with a push rod 36, one end of the push rod 36 is hinged with a connecting rod 37, and the end of the connecting rod 37 away from the push rod 36 is hinged on the side wall of the hollow rod 35. The up-and-down reciprocating sliding of the hollow rod 35, in cooperation with the connecting rod 37, can drive the push rod 36 to slide reciprocally on the inner wall of the bracket 2. The other end of the push rod 36 is fixedly mounted with a limit block 38, the outer wall of the push rod 36 is slidably connected with an aligning plate 39, and the reciprocating movement of the two sets of aligning plates 39 can perform secondary alignment on both sides of the decorative plate and the melamine paper, so that the decorative plate and the melamine paper can move to the lower part of the pressing plate 6 in a neatly stacked state. A slope plate 311 is fixedly mounted on the side of the aligning plate 39 close to the motor 31, and under the guiding effect of the slope plate 311, the decorative plate and the melamine paper will be moved between the two sets of aligning plates 39. The bottoms of the aligning plate 39 and the slope plate 311 both fit against the upper surface of the machine base 1, and the reciprocating movement of the slope plate 311 can perform preliminary alignment on both sides of the decorative plate and the melamine paper. A spring 310 is fixedly mounted on the outer wall of the aligning plate 39, and the end of the spring 310 away from the aligning plate 39 is fixedly mounted on the outer wall of the limit block 38. The spring 310 enables soft contact between the aligning plate 39 and the decorative plate, preventing the aligning plate 39 from causing damage to the decorative plate and the melamine paper.

[0036] with reference to Figure 3 to Figure 4The adjusting mechanism 4 includes a threaded rod 41, which is fixedly installed on the outer wall of the limiting block 38. A knob 42 is threadedly connected to the outer wall of the threaded rod 41. When the knob 42 is rotated, it moves on the surface of the threaded rod 41 due to the threaded connection between the threaded rod 41 and the knob 42. A pull rod 43 is fixedly installed on the side wall of the knob 42. The end of the pull rod 43 away from the knob 42 is located in the gap of the spring 310, and the outer wall of the pull rod 43 is in contact with the outer wall of the spring 310. When the knob 42 gradually moves away from the limiting block 38, the pull rod 43 moves against the surface of the spring 310, and at the same time, the pull rod 43 pulls the spring 310, so that the spring 310 between the pull rod 43 and the limiting block 38 is compressed.

[0037] Working Principle: During operation, decorative panels and melamine paper are stacked on machine base 1. Then, motor 31 is started, driving screw 32 to rotate. The rotation of screw 32 causes push plate 34, which is threadedly connected to it, to slide along the inner wall of machine base 1, gradually approaching bracket 2. When push plate 34 contacts the decorative panels and melamine paper during its sliding motion, it initially aligns them. Simultaneously, push plate 34 pushes the decorative panels and melamine paper towards the pressure plate 6. While screw 32 rotates, it drives L-rod 33 to reciprocate against the inner wall of hollow rod 35. L-rod 33 pushes and pulls hollow rod 35 up and down, causing hollow rod 35 to slide up and down along the inner wall of machine base 1. Simultaneously, the sliding motion of hollow rod 35 pushes and pulls connecting rod 37, causing connecting rod 37 to push and pull push rod 36. At this time, push rod 36 slides back and forth along the inner wall of bracket 2. While sliding back and forth, the limit block 38 moves back and forth synchronously. Under the connection of the spring 310, the limit block 38 moves back and forth, which in turn drives the aligning plate 39 to move back and forth above the machine base 1. While the aligning plate 39 moves back and forth, it drives the inclined plate 311 to move back and forth synchronously. When the push plate 34 pushes the decorative board and melamine paper, the reciprocating movement of the inclined plate 311 can initially align the two sides of the decorative board and melamine paper, so that the decorative board and melamine paper can move between the two sets of aligning plates 39 under the guidance of the inclined plate 311. At this time, the reciprocating movement of the two sets of aligning plates 39 can align the two sides of the decorative board and melamine paper again, so that the decorative board and melamine paper can move to the bottom of the pressure plate 6 in a neat stacked state. Then, the hydraulic cylinder 5 is started to drive the pressure plate 6 to press the decorative board and melamine paper down.

[0038] By rotating the knob 42, the screw rod 41 moves against the outer wall of the threaded rod 41 and gradually moves away from the limiting block 38. During this process, the knob 42 will drive the pull rod 43 to move against the surface of the spring 310. At the same time, the pull rod 43 will pull the spring 310, which will compress the spring 310 between the pull rod 43 and the limiting block 38. As the spring 310 is compressed, it will pull the tidying plate 39, which will slide against the outer wall of the push rod 36 and gradually move closer to the limiting block 38. This will reduce the distance between the tidying plate 39 and the limiting block 38, and further shorten the distance between the two sets of tidying plates 39, so as to tidy up decorative boards and melamine paper of different sizes.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
