[0002] An insulation cotton edge-wrapping machine is a device used to wrap the edges of insulation cotton materials. It mainly uses a mechanical transmission device to transport the insulation cotton material. During the transport process, the edge-wrapping device tightly wraps the edge material around the edge of the insulation cotton. The edge-wrapping material is usually galvanized iron sheet, aluminum foil, etc.
[0003] Existing insulation cotton edging mechanisms typically use a one-time folding method to fold the edging material. However, materials such as sheet metal and aluminum foil have a certain degree of elasticity and are prone to warping during folding. This warping can lead to uneven edging and poor adhesion of the edging material.
[0004] Therefore, it is urgent to improve the folding mechanism of the insulation cotton edging machine to solve the above-mentioned problems. Utility Model Content

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0022] like Figure 1 - Figure 5 As shown, the folding mechanism of the heat insulation cotton edging machine provided in this embodiment includes a base plate 1, a frame 2 fixedly connected to the bottom surface of the base plate 1, a fixed plate 3 fixedly connected to the side of the frame 2, two folding rollers 4 and two folding rollers 5 fixedly installed on the side of the fixed plate 3 near the base plate 1, the folding rollers 4 and folding rollers 5 are used to fold the edging material in sections, the fixed plate 3 is connected to a rolling assembly 7 through a connector 6, the rolling assembly 7 rolls the upper and lower surfaces of the edging that has been bonded with heat insulation cotton again, so that the edging and heat insulation cotton are more tightly bonded, one end of the fixed plate 3 is arc-shaped, and a bending assembly 8 and an edge pressing assembly 9 are fixedly connected to the end of the fixed plate 3 away from the base plate 1, a sleeve 10 is provided at the position of the frame 2 near the arc-shaped end of the fixed plate 3, the sleeve 10 is used to install the edging material. The material first passes through bending assembly 8. After passing through bending assembly 8, the material is bent once on both sides. Then it passes through edge pressing assembly 9, where the material edges are pre-bent downwards to prevent the material edges from warping upwards after bending. Then the material passes through edge folding roller 2 5 and edge folding roller 1 4 to fold the edge material, so that the edge material is attached to the surface of the heat insulation cotton. Since the heat insulation cotton has a certain elasticity, the edge material that has been attached to the heat insulation cotton is rolled by rolling assembly 7 to make the edge and the heat insulation material adhere more tightly. The step-by-step folding method is used to fold the material multiple times. During each folding process, the elastic deformation of the material is relatively small and it is not easy to warp. At the same time, the material edges are pre-bent downwards to reduce the influence of the curvature of the material itself on the folding.
[0023] Among them, such as Figure 2 as well as Figure 5As shown, two folding rollers 1 4 and two folding rollers 2 5 are symmetrically arranged along the base plate 1. The angle between folding roller 1 4 and the base plate 1 is 0 degrees, and the angle between folding roller 2 5 and the base plate 1 is 25 degrees. The edge covering material is bent once when passing through folding roller 2 5 and folding roller 1 4 respectively. When passing through folding roller 1 4, the heat insulation cotton is bonded to the edge covering material.
[0024] Among them, such as 2 and Figure 5 As shown, the bending assembly 8 includes a bending roller 1 801, two bending rollers 2 802, and a bending roller 3 803. The bending roller 1 801 is fixedly connected to the fixed plate 3. One end of the bending roller 2 802 is fixedly connected to the fixed plate 3. The bending roller 3 803 is fixedly connected to the frame 2 through a connector 2 11. The two bending rollers 2 802 are located on the upper and lower sides of the bending roller 1 801. The bending rollers 2 802 and the bending roller 1 801 have a 135-degree angle. When the heat insulation cotton moves, it drives the edge covering material to move. The bending rollers 1 801 and the bending roller 3 803 clamp the two sides of the edge covering material. The 135-degree angle between the bending rollers 2 802 and the bending roller 1 801 causes the edge covering material to be bent when passing through the bending assembly 8.
[0025] Among them, such as 2 and Figure 5 As shown, the edge pressing assembly 9 includes an edge pressing roller 1 901, two edge pressing rollers 2 902, and two edge pressing rollers 3 903. The edge pressing roller 1 901 is fixedly connected to the fixed plate 3. The two edge pressing rollers 2 902 are both fixedly connected to the frame 2 through the connector 3 12. The edge pressing rollers 3 903 are fixedly connected to the fixed plate 3. The edge pressing rollers 3 903 and the edge pressing rollers 2 902 have a 150-degree angle, and the edge pressing rollers 2 902 and the edge pressing roller 1 901 have a 135-degree angle. The edge pressing rollers 2 902 and the edge pressing rollers 1 901 fix the angle of the edge-binding material after passing through the bending assembly 8 again. At the same time, the 150-degree angle between the edge pressing rollers 3 903 and the edge pressing rollers 2 902 causes the edge of the edge-binding material to bend inward by 30 degrees.
[0026] Among them, such as Figure 3 as well as Figure 4As shown, the rolling assembly 7 includes a rolling roller 701, a first sleeve 702, a second sleeve 703, an adjusting bolt 704, and a spring 705. A fixing bracket 14 is fixedly connected to the outer surface of the second sleeve 703, and the other end of the fixing bracket 14 is fixedly connected to the fixing plate 3. The rolling roller 701 is fixed to one end of the first sleeve 702, which is located inside the second sleeve 703. The two ends of the spring 705 abut against the first sleeve 702 and the pressure plate 15, respectively. The adjusting bolt 704 passes through the sleeve. One end of sleeve 703 is threadedly connected to sleeve 703. A limiting hole 16 is provided on the outer side of sleeve 703. A limiting rod 17 is provided on the outer side of sleeve 702. The limiting rod 17 is inserted into the limiting hole 16. The limiting rod 17 and the limiting hole 16 prevent the rolling roller 701 from slipping off and limit the rolling direction of the rolling roller 701. Tighten the adjusting bolt 704. One end of the bolt abuts against the pressure plate 15. The pressure of the rolling roller 701 on the heat insulation cotton is adjusted by adjusting the pressure of the adjusting spring 705.
[0027] like Figure 1 - Figure 5 As shown, the principle of the folding mechanism of the heat insulation cotton edging machine provided in this embodiment is as follows: the edging is tightly bonded to the heat insulation cotton. When the heat insulation cotton moves forward, it drives the edging material to move forward. The edging material is sleeved on the sleeve 10. When the edging material moves forward, it first passes through the bending component 8. After passing through the bending component 8, the material is bent once on both sides. Then it passes through the pressing component 9, which pre-bends the material edge downward to prevent the material edge from warping upward after bending. Then the material passes through the second folding roller 5 and the first folding roller 4 to fold the edging material, so that the edging material is bonded to the surface of the heat insulation cotton. Since the heat insulation cotton has a certain elasticity, the edging material that has been bonded to the heat insulation cotton is rolled by the rolling component 7 to make the edging and the heat insulation material bond more tightly. The step-by-step folding method is adopted to fold the material multiple times. During each folding process, the elastic deformation of the material is relatively small and it is not easy to warp. At the same time, the edge of the material is pre-bent downward to reduce the influence of the curvature of the material itself on the folding.
