Description

Technical Field

[0001] This utility model belongs to the field of polyurethane cold storage panel production technology, and in particular, it relates to a polyurethane cold storage panel molding device. Background Technology

[0002] Polyurethane cold storage panels are a type of material used for building refrigeration, insulation, and heat insulation. They are made of two layers of color steel plates with a layer of polyurethane foam sandwiched between them. In the existing polyurethane cold storage panel molding process, there are no positioning structures on the sides of the polyurethane cold storage panels. When the polyurethane cold storage panels are transported to the molding device, they may shift. If the shifted polyurethane cold storage panels are not moved and straightened, the molding effect will be affected.

[0003] A search revealed a Chinese patent document (authorization announcement number CN221913322U) entitled "A Polyurethane Cold Storage Panel Molding Device," relating to the technical field of polyurethane cold storage panels. The device includes a workbench, an adhesive tank, a feeding rack, and a working groove. The adhesive tank is located on the upper surface of the workbench, and the working groove is located on one side of the adhesive tank. The feeding rack is fixedly connected to one end of the workbench, and a pushing mechanism is provided on the inner wall of the working groove. While this device facilitates the feeding of the polyurethane cold storage panels after molding, in actual use, the polyurethane panels to be molded need to be manually placed and aligned in the working groove. Because there is no structure for positioning the polyurethane cold storage panels, problems such as misalignment are prone to occur during molding. Utility Model Content

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

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyurethane cold storage panel molding device, comprising a base plate for installing the polyurethane cold storage panel molding device and a conveyor belt for conveying the polyurethane cold storage panel, wherein two vertical plates are symmetrically and fixedly installed on the top surface of the base plate;

[0006] Multiple hydraulic cylinders are fixedly installed on opposite sides of the two vertical plates. Push plates are fixedly installed on the telescopic ends of the multiple hydraulic cylinders, and multiple limiting cylinders are fixedly installed on the side of the push plates away from the hydraulic cylinders. Telescopic rods are slidably installed inside the limiting cylinders, and clamping plates are fixedly installed at the ends of the telescopic rods.

[0007] A spring is fixedly installed on the inner wall of the limiting cylinder, and the end of the spring is fixedly connected to the end of the telescopic rod.

[0008] Two strip-shaped holes are symmetrically opened on the side wall of one of the vertical plates, and a slider is slidably installed in the strip-shaped holes. An mounting plate is fixedly installed on the side wall of the slider. A cylinder is fixedly installed on the side wall of the vertical plate, and the telescopic end of the cylinder slides into the strip-shaped hole and is fixedly connected to the slider.

[0009] Preferably, the ends of the two mounting plates are hinged to connecting plates.

[0010] Preferably, limit blocks are symmetrically fixedly installed on the sidewalls of both sliders, and limit grooves are symmetrically formed on the inner wall of the strip hole.

[0011] Preferably, the two limiting blocks fixedly installed on the side wall of the slider are slidably connected to the inside of the two limiting grooves opened in the inner wall of the strip hole.

[0012] Preferably, the inner wall of the limiting cylinder has two symmetrically formed grooves, and the side wall of the telescopic rod has two rectangular blocks symmetrically fixedly installed.

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

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] This polyurethane cold storage panel molding device, thanks to the design of hydraulic cylinders, push plates, limit cylinders, telescopic rods, and clamping plates, transports the polyurethane cold storage panels to be processed to the bottom of the pressing plate via a conveyor belt. Then, multiple hydraulic cylinders are activated, which drive the push plate and clamping plate to move closer to the polyurethane cold storage panel. The clamping plate squeezes the polyurethane cold storage panel and positions it in the center of the bottom plate, thus improving the molding effect of the polyurethane cold storage panel.

[0016] This polyurethane cold storage panel molding device benefits from the setting of structures such as limiting cylinder, spring, telescopic rod and clamping plate. When the clamping plate comes into contact with the polyurethane cold storage panel under the push of the hydraulic cylinder, the clamping plate will push the telescopic rod to retract into the limiting cylinder and compress the spring. The compression stroke of the spring buffers the clamping plate and prevents the hydraulic cylinder from pushing the clamping plate into hard contact with the polyurethane cold storage panel, which would cause the polyurethane cold storage panel to deform.

[0017] This polyurethane cold storage panel molding device, thanks to the design of the strip hole, slider, mounting plate and cylinder, places the upper color steel plate of the polyurethane cold storage panel in the predetermined position, and then starts the cylinder to drive the two mounting plates to move closer to the color steel plate, so that the color steel plate is positioned above the polyurethane cold storage panel.

[0018] Compared with existing technologies, this polyurethane cold storage panel molding device can effectively and automatically position polyurethane panels, thereby further improving the molding effect of polyurethane cold storage panels. Attached Figure Description

[0027] 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.

[0028] 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.

[0029] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0030] like Figures 1 to 5The main structure of a polyurethane cold storage panel molding device shown is a base plate 1 for installing the polyurethane cold storage panel molding device and a conveyor belt 2 for conveying polyurethane cold storage panels. Two vertical plates 3 are symmetrically fixedly installed on the top surface of the base plate 1. A fixing frame 14 is fixedly installed between the outer sides of the two vertical plates 3. A pressure plate 15 is installed at the bottom of the fixing frame 14.

[0031] Multiple hydraulic cylinders 4 are fixedly installed on one side of the two vertical plates 3. Push plates 5 are fixedly installed at the ends of the multiple hydraulic cylinders 4. Multiple limiting cylinders 6 are fixedly installed on the side of the push plates 5 away from the hydraulic cylinders 4. Telescopic rods 7 are slidably installed inside the limiting cylinders 6. Clamping plates 8 are fixedly installed at the ends of the telescopic rods 7. Thanks to the structure of hydraulic cylinders 4, push plates 5, limiting cylinders 6, telescopic rods 7 and clamping plates 8, the polyurethane cold storage panels to be processed are transported to the bottom of the pressure plate 15 by the conveyor belt 2. Then, the multiple hydraulic cylinders 4 are activated to drive the push plates 5 and clamping plates 8 fixedly installed at their telescopic ends to move closer to the polyurethane cold storage panels. The clamping plates 8 squeeze the polyurethane cold storage panels and position them in the center of the bottom plate 1, thereby improving the molding effect of the polyurethane cold storage panels.

[0032] A spring 9 is fixedly installed on the inner wall of the limiting cylinder 6. The end of the spring 9 is fixedly connected to the end of the telescopic rod 7. Thanks to the structure of the limiting cylinder 6, the spring 9, the telescopic rod 7, and the clamping plate 8, when the clamping plate 8 is pushed by the hydraulic cylinder 4 and comes into contact with the polyurethane cold storage panel, the clamping plate 8 will push the telescopic rod 7 to retract into the limiting cylinder 6 and compress the spring 9. The compression stroke of the spring 9 will buffer the clamping plate 8 and prevent the hydraulic cylinder 4 from pushing the clamping plate 8 into hard contact with the polyurethane cold storage panel, which would cause the polyurethane cold storage panel to deform.

[0033] Two strip holes 10 are symmetrically opened on the side wall of one of the vertical plates 3, and a slider 11 is slidably installed in the strip hole 10. An mounting plate 12 is fixedly installed on the side wall of the slider 11. A cylinder 13 is fixedly installed on the side wall of the vertical plate 3, and the telescopic end of the cylinder 13 slides into the strip hole 10 and is fixedly connected to the slider 11. Thanks to the arrangement of the strip hole 10, slider 11, mounting plate 12 and cylinder 13, after the upper color steel plate of the polyurethane cold storage panel is placed in the predetermined position, the cylinder 13 is activated to drive the two mounting plates 12 to move closer to the color steel plate, so that the color steel plate is positioned above the polyurethane cold storage panel.

[0034] The ends of the two mounting plates 12 are hinged with connecting plates 17, which can be flipped upwards and contact the top surface of the mounting plates 12 when not in use, thereby facilitating the unloading of the polyurethane cold storage panels.

[0035] Limiting blocks 16 are symmetrically fixedly installed on the side walls of the two sliders 11. Limiting grooves are symmetrically opened on the inner wall of the strip hole 10. The two limiting blocks 16 fixedly installed on the side walls of the sliders 11 are slidably connected to the inside of the two limiting grooves opened on the inner wall of the strip hole 10. The limiting blocks 16 can effectively improve the stability of the sliders 11 when sliding, and further limit the sliding direction of the sliders 11.

[0036] The inner wall of the limiting cylinder 6 has two symmetrically formed slots, and the side wall of the telescopic rod 7 has two rectangular blocks 18 fixedly installed symmetrically. The two rectangular blocks 18 fixedly installed on the side wall of the telescopic rod 7 are slidably connected to the inside of the two slots formed in the inner wall of the limiting cylinder 6. The rectangular blocks 18 can further improve the stability of the telescopic rod 7 when it slides.

[0037] Working principle

[0038] In use, the polyurethane cold storage panel molding device first places the polyurethane cold storage panel on the conveyor belt 2 and transports it to the area below the pressure plate 15. At the same time, multiple hydraulic cylinders 4 are activated, which drive the push plate 5 installed at its telescopic end to move, indirectly driving the clamping plate 8 to approach the polyurethane cold storage panel until it contacts it. When the clamping plate 8 contacts the polyurethane cold storage panel, it pushes the telescopic rod 7 to retract into the limiting cylinder 6 and compresses the spring 9, thereby positioning the polyurethane cold storage panel directly below the pressure plate 15. The two connecting plates 17 are flipped to a horizontal horizontal state, and the two cylinders 13 are activated to drive the slider 11 and the mounting plate 12, along with the connecting plate 17, to move towards the upper color steel plate of the polyurethane cold storage panel. The connecting plate 17 pushes the color steel plate to move above the polyurethane cold storage panel, thereby further improving the molding effect of the polyurethane cold storage panel.
