Description

Technical Field

[0001] This utility model belongs to the field of polyurethane cold storage panel processing technology, and in particular, it is a polyurethane cold storage panel composite coating device. Background Technology

[0002] Polyurethane cold storage panels use lightweight polyurethane as the core material. Polyurethane's advantage lies in its excellent thermal insulation properties. The exterior of the polyurethane cold storage panel is composed of color steel plates and stainless steel plates. The polyurethane cold storage panel is bonded between the color steel plates and stainless steel plates, therefore, adhesive needs to be applied to the side walls of the polyurethane cold storage panel. However, most existing adhesive application devices use conveyor belts to transport the polyurethane cold storage panel to the bottom of the adhesive application device. Furthermore, current conveyor devices lack structures for limiting and aligning the polyurethane cold storage panel. Therefore, vibrations generated during mechanical operation during transport can easily cause displacement of the polyurethane cold storage panel, directly affecting the adhesive application effect.

[0003] A search revealed a Chinese patent document (authorization announcement number CN221656915U) entitled "A Coating Device for Polyurethane Cold Storage Panel Composites," relating to the field of polyurethane cold storage panel processing. This coating device includes a frame, with a conveyor belt component installed inside the frame for transporting the polyurethane cold storage panels. A coating mechanism is located on the upper side of the frame, comprising a coating pipe assembly, a coating roller assembly, and an adjustable mounting assembly. While the device uses springs and other structures to ensure a tighter fit between the coating roller and the polyurethane cold storage panel, thus improving the coating effect, in actual use, the device lacks any structure for limiting or aligning the polyurethane cold storage panel. Therefore, if the panel shifts due to mechanical operation or accidental human contact, it directly affects the subsequent coating effect. Thus, a polyurethane cold storage panel composite coating device is urgently needed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a polyurethane cold storage panel composite adhesive coating device to solve the problems mentioned in the background art.

[0005] 2. To achieve the above objectives, this utility model provides the following technical solution: a polyurethane cold storage panel composite adhesive coating device, comprising an installation plate for polyurethane cold storage panel adhesive coating installation and polyurethane cold storage panel adhesive coating nozzles, wherein a conveyor belt is rotatably installed on the outer wall of the installation plate, vertical plates are symmetrically fixedly installed on the top side wall of the installation plate, and two horizontal pipes are fixedly installed between the two vertical plates, and multiple adhesive coating nozzles are connected and installed between the two vertical plates.

[0006] The mounting plate has horizontal plates fixedly installed symmetrically on its side wall, and the top surface of the horizontal plates has a strip groove. A slider is slidably connected in the strip groove, and a guide plate is fixedly installed on the side of the slider near the conveyor belt, and the guide plate extends above the conveyor belt.

[0007] Multiple limiting cylinders are fixedly installed on the opposite side walls of the two vertical plates, and telescopic rods are slidably installed inside the limiting cylinders, with push plates fixedly installed at the ends of the multiple telescopic rods;

[0008] A push spring is fixedly installed on the inner wall of the limiting cylinder, and the end of the push spring is fixedly connected to the end of the telescopic rod.

[0009] Preferably, the two push plates and guide plates have vertical grooves on their opposite sidewalls, and rollers are rotatably installed inside the vertical grooves.

[0010] Preferably, rectangular blocks are symmetrically fixedly installed on the sidewalls of the slider, and two rectangular grooves are symmetrically formed on the inner wall of the strip groove.

[0011] Preferably, the two rectangular blocks fixedly installed on the sidewall of the slider are slidably connected to the interior of the two rectangular slots opened on the inner wall of the strip groove.

[0012] Preferably, the inner walls of the plurality of limiting cylinders are symmetrically provided with two limiting grooves, and the side walls of the telescopic rod are symmetrically fixedly installed with two limiting blocks.

[0013] Preferably, the two limiting blocks fixedly installed on the side wall of the telescopic rod are slidably connected to the inside of the two limiting grooves opened in the inner wall of the limiting cylinder.

[0014] Preferably, a push rod is threaded through the top surface of the slider, and the bottom of the push rod extends into the lower part of the groove.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This polyurethane cold storage panel composite coating device, thanks to the design of the horizontal plate, strip groove, slider and guide plate, can effectively straighten the polyurethane cold storage panel by extending the two guide plates above the conveyor belt. At the same time, the length of the two guide plates extending above the conveyor belt can be adjusted by sliding the slider along the two strip grooves, so as to straighten polyurethane cold storage panels of different widths.

[0017] This polyurethane cold storage panel composite coating device benefits from the setting of structures such as vertical plates, limiting cylinders, telescopic rods, push springs, and push plates. After the polyurethane cold storage panel is aligned by two guide plates and then contacts two push plates, multiple push springs push the telescopic rods and the push plates at the ends of the telescopic rods to slide and limit the polyurethane cold storage panel, thereby further improving the stability of the polyurethane cold storage panel when it moves.

[0018] This polyurethane cold storage panel composite coating device benefits from the fact that multiple rollers are rotatably installed on the contact surfaces of the push plate and guide plate with the polyurethane cold storage panel, which can effectively reduce the friction between the polyurethane guide plate and the guide plate and push plate, thereby effectively improving the sliding effect of the polyurethane cold storage panel.

[0019] Compared with existing technologies, this polyurethane cold storage panel composite adhesive coating device can effectively align and stably transport polyurethane cold storage panels, thereby effectively improving the adhesive coating effect. Attached Figure Description

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0028] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0029] like Figures 1 to 3 The main structure of the polyurethane cold storage panel composite adhesive application device shown is an installation plate 2 for polyurethane cold storage panel adhesive application and a polyurethane cold storage panel adhesive application nozzle 14. A support column 1 is fixedly installed at the bottom of the installation plate 2, and a conveyor belt 3 is rotatably installed on the outer wall of the installation plate 2. Vertical plates 4 are symmetrically fixedly installed on the top side wall of the installation plate 2, and two horizontal pipes 13 are fixedly installed between the two vertical plates 4. Multiple adhesive application nozzles 14 are connected and installed between the two vertical plates 4. The adhesive application nozzles 14 are evenly arranged at the bottom of the horizontal pipes 13, so that the adhesive can be evenly sprayed onto the surface of the polyurethane cold storage panel through the adhesive application nozzles 14.

[0030] A horizontal plate 5 is symmetrically fixed to the side wall of the mounting plate 2. A strip groove 6 is opened on the top surface of the horizontal plate 5. A slider 7 is slidably connected in the strip groove 6. A guide plate 8 is fixedly installed on the side of the slider 7 near the conveyor belt 3. The guide plate 8 extends above the conveyor belt 3. Thanks to the structure of the horizontal plate 5, the strip groove 6, the slider 7 and the guide plate 8, the polyurethane cold storage panel can be effectively aligned by the two guide plates 8 extending above the conveyor belt 3. At the same time, the length of the two guide plates 8 extending above the conveyor belt 3 can be adjusted by the slider 7 sliding along the two strip grooves 6, so that polyurethane cold storage panels of different widths can be aligned.

[0031] Multiple limiting cylinders 9 are fixedly installed on the opposite side walls of the two vertical plates 4, and telescopic rods 10 are slidably installed inside the limiting cylinders 9. Push plates 11 are fixedly installed at the ends of the multiple telescopic rods 10. Push springs 17 are fixedly installed on the inner wall of the limiting cylinders 9, and the ends of the push springs 17 are fixedly connected to the ends of the telescopic rods 10. Thanks to the structure of the vertical plates 4, limiting cylinders 9, telescopic rods 10, push springs 17 and push plates 11, after the polyurethane cold storage panel is aligned by the two guide plates 8 and comes into contact with the two push plates 11, the multiple push springs 17 push the telescopic rods 10 and the push plates 11 at the ends of the telescopic rods 10 to slide and limit the polyurethane cold storage panel, thereby further improving the stability of the polyurethane cold storage panel when it moves.

[0032] Vertical grooves are provided on the opposite side walls of the two push plates 11 and the guide plate 8, and rollers 12 are rotatably installed inside the vertical grooves. Thanks to the fact that multiple rollers 12 are rotatably installed on the contact surfaces of the push plates 11 and the guide plate 8 with the polyurethane cold storage panel, the friction between the polyurethane guide plate 8 and the guide plate 8 and the push plate 11 can be effectively reduced, thereby effectively improving the sliding effect of the polyurethane cold storage panel.

[0033] Rectangular blocks 16 are symmetrically fixedly installed on the side wall of slider 7. Two rectangular slots are symmetrically opened on the inner wall of strip groove 6. The two rectangular blocks 16 fixedly installed on the side wall of slider 7 are slidably connected to the inside of the two rectangular slots opened on the inner wall of strip groove 6. The two rectangular blocks 16 can effectively limit the sliding direction of slider 7, and further improve the stability of slider 7 when sliding with guide plate 8.

[0034] Two limiting grooves are symmetrically opened on the inner wall of multiple limiting cylinders 9, and two limiting blocks 18 are symmetrically fixedly installed on the side wall of the telescopic rod 10. The two limiting blocks 18 fixedly installed on the side wall of the telescopic rod 10 are slidably connected to the inside of the two limiting grooves opened on the inner wall of the limiting cylinder 9. Thanks to the setting of the limiting blocks 18, the stability of the telescopic rod 10 and the push plate 11 when sliding can be further improved.

[0035] The top surface of the slider 7 is threaded through and fitted with a push rod 15, and the bottom of the push rod 15 extends into the lower part of the inside of the strip groove 6. When the slider 7 slides to the predetermined position of the strip groove 6 as required, the bottom of the push rod 15 will be abutted against the lower part of the inside of the strip groove 6 by rotating the push rod 15, thereby effectively fixing the position of the slider 7.

[0036] Working principle

[0037] In use, when the polyurethane cold storage panel composite coating device is driven by the conveyor belt 3 and approaches the coating nozzle 14, the polyurethane cold storage panel will first contact the two guide plates 8 and the rollers 12 on the side wall of the guide plates 8. In this way, the two guide plates 8 can straighten the polyurethane cold storage panel that has deviated. Then, the straightened polyurethane cold storage panel will contact the multiple rollers 12 on the side wall of the two push plates 11. By pushing the telescopic rod 10 and the push plate 11 fixedly installed at the end of the telescopic rod 10 with multiple push springs 17, the stability of the polyurethane cold storage panel when it is conveyed by the conveyor belt 3 is improved, thereby effectively improving the coating effect of the subsequent coating nozzle 14 on the polyurethane cold storage panel.
