Description

Technical Field

[0001] This utility model relates to the field of aluminum-plastic coating machine technology, and in particular to a four-sided pressing device for an aluminum-plastic coating machine. Background Technology

[0002] The aluminum-plastic coating machine uses aluminum profiles to coat the surface with a layer of PE plastic. The coating thickness is about 1 mm on each side. The gap of the mold is also 1 mm with a 0.2 mm allowance. Generally, the lower part uses stainless steel or flat rods for positioning, and the upper pressing uses a rod to press directly on the aluminum profile, which is difficult to adjust and makes it difficult to enter the mold. It is difficult to adjust for different specifications of aluminum profiles, which wastes a lot of manpower.

[0003] In the current technology, aluminum profiles on the market have different specifications. Different specifications of aluminum profiles are difficult to adjust and have high resistance. In addition, the upper clamping device cannot adjust the clamping force according to the aluminum profile, which can easily cause the mold to jam or the aluminum profile to block the mold. This results in a lot of manual labor, a high scrap rate, and an increased burden on enterprises. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0029] Reference Figure 1 As shown, this utility model discloses a four-sided pressing device for an aluminum-plastic coating machine, comprising:

[0030] Mounting bracket 1;

[0031] The horizontal adjustment assembly 2 includes a pair of vertical rollers 21, a first lead screw 22, and a first elastic element 23. The pair of vertical rollers 21 are arranged in the mounting frame 1 along the height direction of the mounting frame 1. The pair of first lead screws 22 pass through the mounting frame 1 and are respectively connected to the two ends of the vertical rollers 21. The first lead screws 22 are fixedly connected to the mounting frame 1. The first elastic element 23 is arranged between the first lead screw 22 and the vertical rollers 21.

[0032] The vertical adjustment assembly 3 includes a support roller 31, a pressure roller 32, a second elastic element 33, a pair of second lead screws 34, and a pair of lugs 35. The support roller 31 and the pressure roller 32 are both arranged inside the mounting frame 1 along the width direction of the mounting frame 1. The pressure roller 32 is arranged on the top of the support roller 31. The pair of lugs 35 are arranged on both sides of the mounting frame 1. The second lead screws 34 pass through the lugs 35 along the height direction of the mounting frame 1. The pair of second lead screws 34 are connected to the two ends of the pressure roller 32. The second elastic element 33 is sleeved on the outside of the second lead screws 34, and the two ends of the second elastic element 33 abut against the lugs 35 and the pressure roller 32, respectively.

[0033] In this utility model, the mounting bracket 1 is used for mounting the horizontal adjustment component 2 and the vertical adjustment component 3. The horizontal adjustment component 2 is used to adjust the clamping force of the aluminum profile in the horizontal direction. Specifically, refer to... Figures 2-4 As shown, two vertical rollers 21 are arranged along the height direction of the mounting frame 1. Both ends of each vertical roller 21 are connected to the mounting frame 1 via a first lead screw 22. The first lead screw 22 is threadedly connected to the mounting frame 1. The distance between the two vertical rollers 21 is adjusted by the first lead screw 22 to accommodate aluminum profiles of different widths. A first elastic element 23 is provided between the lead screw and the vertical roller 21. When the aluminum profile passes between the two vertical rollers 21, the pressure between the vertical roller 21 and the aluminum profile is dynamically adjusted by the first elastic element 23, facilitating the horizontal adjustment of aluminum profiles of different shapes and preventing jamming between the aluminum profile and the mold in the horizontal direction. In the vertical adjustment assembly 3, the support roller 31 and the pressure roller 32 are arranged along the width direction of the mounting frame 1. The support roller 31 is fixedly connected to the mounting frame 1, and the pressure roller 32 is connected to the mounting frame 1 via a second lead screw 34. Specifically, the second lead screw 34 passes through the ear plate and can move within the ear plate. The second elastic element 33 is located between the ear plate and the support roller 31. The aluminum profile is pressed by the tension of the elastic element. When aluminum profiles of different shapes pass between the pressure roller 32 and the support roller 31, the second elastic element 33 is compressed, adjusting the pressure of the pressure roller 32 and the surface of the aluminum profile in the vertical direction, so as to avoid the aluminum profile and the mold getting stuck in the vertical direction.

[0034] The four-sided pressing device of the aluminum-plastic coating machine in this utility model can effectively solve the problem of convenient adjustment of aluminum profiles of different specifications, solve the problem of jamming between aluminum profiles and molds caused by deformation, ensure the continuity of production products, and improve the production quality of products.

[0035] Furthermore, the horizontal adjustment assembly 2 also includes a handwheel 24, which is connected to the end of the first lead screw 22 away from the vertical roller 21. Specifically, the handwheel 24 can be used to rotate the first lead screw 22 to adjust the distance between the two vertical rollers 21.

[0036] Furthermore, a clamping platform 221 is provided at one end of the first lead screw 22 connected to the vertical roller 21, and the first elastic element 23 is sleeved on the outside of the first lead screw 22, with both ends of the first elastic element 23 abutting against the clamping platform 221 and the vertical roller 21 respectively.

[0037] Specifically, in the actual assembly process, the first elastic element 23 is installed on the side of the first lead screw 22 where the clamping platform 221 is provided, so that one end of the first elastic element 23 abuts against the end face of the clamping platform 221, and the other end of the first elastic element 23 abuts against the vertical roller 21, so that the tension of the first elastic element 23 can be effectively transmitted to the vertical roller 21.

[0038] Furthermore, a pin hole 222 is provided at one end of the first lead screw 22 near the vertical roller 21, and a positioning pin 25 is inserted into the pin hole 222.

[0039] Specifically, in the actual assembly process, the end of the first lead screw 22 with the locking plate 221 is connected to the vertical roller 21. First, the first elastic element 23 is sleeved on the first lead screw, then the first lead screw 22 is passed through the vertical roller 21, and finally the positioning pin 25 is inserted into the pin hole 222 to complete the connection between the first lead screw 22 and the vertical roller 21. The positioning pin 25 can ensure the stability of the connection between the first lead screw 22 and the vertical roller 21.

[0040] Furthermore, the vertical adjustment assembly 3 also includes a limiting nut 36, which is sleeved on the outside of the second lead screw 34, and the limiting nut 36 is in contact with the side of the lug 35 away from the second elastic element 33.

[0041] Specifically, the limiting nut 36 is installed at the end of the second lead screw 34 away from the pressure roller 32. The height of the second lead screw 34 can be adjusted by the limiting nut 36. In actual operation, the limiting nut 36 is adjusted according to the height of the aluminum profile, thereby adjusting the height of the pressure roller 32.

[0042] Furthermore, a connector 37 is provided between the second lead screw 34 and the pressure roller 32. One end of the connector 37 is fixedly connected to the second lead screw 34, and the other end of the connector 37 is rotatably connected to the pressure roller 32.

[0043] Specifically, refer to Figure 4 and Figure 6As shown, in the actual assembly process, the second lead screw 34 is threadedly connected and fixed to the connecting piece 37. The second elastic element 33 is sleeved on the second lead screw 34, and both ends of the second elastic element 33 abut against the lug 35 and the connecting piece 37, respectively. A bearing 38 is embedded inside the end of the connecting piece 37 that connects to the pressure roller 32, and the pressure roller 32 is connected to the bearing 38. As a preferred embodiment of this utility model, the bearing 38 is a spherical joint bearing 38, which can adapt to the needs of multi-directional movement. The spherical joint bearing 38 can flexibly adapt to complex motion trajectories and meet the surface requirements of different aluminum profiles with different shapes.

[0044] Furthermore, the mounting frame 1 includes a pair of side plates 11 and a pair of positioning rods 12, with the pair of positioning rods 12 disposed between the two side plates 11. A pair of vertical rollers 21 are disposed between the two positioning rods 12, with the vertical rollers 21 being perpendicular to the positioning rods 12; the pressure roller 32 and the support roller 31 are disposed between the two positioning rods 12, with the pressure roller 32 and the support roller 31 being parallel to the positioning rods 12.

[0045] Furthermore, the side plate 11 is provided with adjustment holes 111 that cooperate with the pressure roller 32.

[0046] Specifically, refer to Figure 5 As shown, the adjusting hole 111 is an elongated hole. In the actual installation process, both ends of the pressure roller 32 are passed through the elongated hole, and then the pressure roller 32 is connected to the second lead screw 34. When an aluminum profile passes between the pressure roller 32 and the support roller 31, the second elastic element 33 is compressed, and both ends of the pressure roller 32 are adjusted up and down within the adjusting hole 111.

[0047] In summary, this utility model introduces a four-sided pressing device for an aluminum-plastic coating machine. The pressing holes formed between the horizontal adjustment component 2 and the vertical adjustment component 3 allow for the placement of multiple pressing devices on the traction line. The aluminum profile passes through the pressing holes, pressing it from all four sides for positioning. The horizontal adjustment component 2 adjusts the horizontal pressing force on the aluminum profile, while the vertical adjustment component 3 adjusts the vertical pressing force. This effectively solves the problem of convenient adjustment for aluminum profiles of different specifications, prevents jamming between the aluminum profile and the mold due to deformation, ensures the continuity of production, and improves product quality.
