Description

Technical Field

[0001] This utility model relates to the field of vacuum insulation panel folding technology, and in particular to a corner pinching mechanism. Background Technology

[0002] Vacuum insulation panels are a new type of high-efficiency insulation material based on the principle of vacuum insulation. They combine the advantages of vacuum insulation, microporous insulation and multilayer insulation, thus having outstanding insulation effect.

[0003] After the vacuum insulation panel is encapsulated, its edges need to be folded to ensure a neat overall shape and facilitate use. After folding the long side panels, the short side panels need to be folded as well. Before folding the short side panels, the corners at the connection points between the short and long side panels must be pinched to prevent the long side panels from being exposed under the cover of the short side panels after folding. Traditionally, this pinching is done manually, which is inefficient and costly. Utility Model Content

[0004] Based on the aforementioned problems in the existing technology, the purpose of this application embodiment is to provide a corner pinching mechanism, which automatically pinches the connection position of the short side leaf and the long side leaf by setting a forming component and a folding and rolling component, with high corner pinching efficiency.

[0005] The technical solution adopted by this application to solve its technical problem is: a pinching mechanism, including a base, a forming component and a folding and rolling component;

[0006] The molding assembly includes a molding drive and a molding insert. The molding drive is mounted on a base, and the molding insert is connected to and driven by the molding drive. The hemming and rolling assembly includes a rolling drive, a first roller, and a second roller. The rolling drive is mounted on a base, and the first roller is connected to and driven by the molding drive. The second roller is connected to and driven by the molding drive. A deformation cavity is formed between the second roller and the first roller, and the deformation cavity is positioned opposite to the molding insert.

[0007] Furthermore, the molding insert is a molding ejector pin, which is set at an angle downwards.

[0008] Furthermore, the forming push rod includes a connecting section and an insertion section. One end of the connecting section is connected to the forming drive component, and the insertion section is connected to the other end of the connecting section. The inner diameter of the insertion section gradually decreases from the direction close to the connecting section to the direction far away from the connecting section, and the outer surface of the insertion section forms an arc surface.

[0009] Furthermore, the molding drive component includes a first molding drive cylinder and a second molding drive cylinder. The first molding drive cylinder is connected to the base through a first connecting plate, and the second molding drive cylinder is connected to the first molding drive cylinder through a second connecting plate and is driven by the first molding drive cylinder to move horizontally. The molding insert is connected to the second molding drive cylinder and is driven by the second molding drive cylinder to move vertically.

[0010] Furthermore, the molding insert is a molding lever, which is rotatably mounted on the molding drive component.

[0011] Furthermore, it also includes a pre-compression assembly, which includes a pre-compression drive and a pre-compression block. The pre-compression block is connected to the pre-compression drive and is driven to move by the pre-compression drive. The pre-compression block is located outside the first roller.

[0012] Furthermore, the pre-pressure drive component includes a first pre-pressure drive cylinder and a second pre-pressure drive cylinder. The first pre-pressure drive cylinder is connected to the base through a third connecting plate, and the second pre-pressure drive cylinder is connected to the first pre-pressure drive cylinder through a fourth connecting plate. The first pre-pressure drive cylinder drives the second pre-pressure drive cylinder to move horizontally. The pre-pressure block is connected to the second pre-pressure drive cylinder and is driven to move vertically by the second pre-pressure drive cylinder.

[0013] Furthermore, it also includes a leveling assembly, which includes a leveling cylinder and a scraper plate. The leveling cylinder is located on the fourth connecting plate and is arranged side by side with the second pre-pressure drive cylinder. The scraper plate is connected to the leveling cylinder and is driven by the leveling cylinder to move vertically.

[0014] The beneficial effects of this application are as follows: During use, the vacuum insulation panel is conveyed to the corner-pinching mechanism. The forming drive drives the forming insert to move horizontally and vertically, thereby inserting the forming insert into the connection position between the long and short side blades. The movement of the forming insert causes deformation at the connection position between the long and short side blades. Then, the rolling drive drives the first roller and the second roller to move along the surface of the side blades. The first roller is located on one side of the forming insert, and the second roller is located on the other side of the forming insert, thereby forming a crease at the connection position between the long and short side blades, completing the corner pinching of the vacuum insulation panel. Therefore, this utility model, by setting a forming component and a folding and rolling component, achieves automatic corner pinching at the connection position between the short and long side blades, resulting in high corner pinching efficiency.

Detailed Implementation

[0020] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 3 As shown, a corner pinching mechanism of this utility model includes a base 1, a forming component 2, and a folding and rolling component 3. The forming component 2 includes a forming drive 21 and a forming insert 22. The forming drive 21 is disposed on the base 1. The forming insert 22 is connected to the forming drive 21 and is driven to move by the forming drive 21. The folding and rolling component 3 includes a rolling drive 31, a first roller 32, and a second roller 33. The rolling drive 31 is disposed on the base 1. The first roller 32 is connected to the rolling drive 31 and is driven to move by the forming drive 21. The second roller 33 is connected to the rolling drive 31 and is driven to move by the forming drive 21. A deformation cavity is formed between the second roller 33 and the first roller 32. The deformation cavity is disposed opposite to the forming insert 22.

[0022] Thus, in use, the corner-pinching mechanism of this utility model involves conveying a vacuum insulation panel to the corner-pinching mechanism. The forming drive 21 drives the forming insert 22 to move horizontally and vertically, causing the forming insert 22 to insert into the connection position between the long and short side blades. The movement of the forming insert 22 deforms the connection position between the long and short side blades. Then, the rolling drive 31 drives the first roller 32 and the second roller 33 to move along the surface of the side blades. The first roller 32 is located on one side of the forming insert 22, and the second roller 33 is located on the other side, thus forming a crease at the connection position between the long and short side blades, completing the corner pinching of the vacuum insulation panel. Therefore, this utility model, by setting the forming component 2 and the folding and rolling component 3, achieves automatic corner pinching at the connection position between the short and long side blades, resulting in high corner pinching efficiency.

[0023] Optionally, the molding insert 22 is a molding ejector pin 221, and the molding ejector pin 221 is inclined downward. The molding ejector pin 221 moves horizontally and vertically under the action of the molding drive member 21, which facilitates the insertion of the molding ejector pin 221 into the connection position of the long side leaf and the short side leaf. Since the molding ejector pin 221 is inclined downward, when the molding ejector pin 221 rises, it will cause the connection position of the long side leaf and the short side leaf to undergo an upward deformation, resulting in a better pinching effect.

[0024] like Figure 2 As shown, in this embodiment, the forming push rod 221 includes a connecting section 2211 and an insertion section 2212. One end of the connecting section 2211 is connected to the forming drive member 21, and the insertion section 2212 is connected to the other end of the connecting section 2211. The inner diameter of the insertion section 2212 gradually decreases from near the connecting section 2211 to far away from the connecting section 2211, and the outer surface of the insertion section 2212 forms an arc surface. This facilitates the insertion of the forming push rod 221 into the connection position between the long and short blades, and the insertion process does not damage the blades of the vacuum insulation plate.

[0025] Furthermore, the molding drive component 21 includes a first molding drive cylinder 211 and a second molding drive cylinder 212. The first molding drive cylinder 211 is connected to the base 1 via a first connecting plate 213, and the second molding drive cylinder 212 is connected to the first molding drive cylinder 211 via a second connecting plate 214. The first molding drive cylinder 211 drives the first molding drive cylinder 211 to move horizontally. The molding insert 22 is connected to the second molding drive cylinder 212 and is driven to move vertically by the second molding drive cylinder 212. By setting the first molding drive cylinder 211 and the second molding drive cylinder 212, the horizontal and vertical displacement of the molding insert 22 is achieved under the action of the first molding drive cylinder 211 and the second molding drive cylinder 212.

[0026] In another preferred embodiment of this invention, the molding insert 22 is a molding lever, which is rotatably mounted on the molding drive component 21. Thus, by rotating the molding lever, the connection point between the long and short blades can be deformed.

[0027] In this embodiment, a pre-compression assembly 4 is also included. The pre-compression assembly 4 includes a pre-compression drive 41 and a pre-compression block 42. The pre-compression block 42 is connected to the pre-compression drive 41 and is driven to move by the pre-compression drive 41. The pre-compression block 42 is located outside the first roller 32. After a pinched corner is formed at the connection position of the long side blade and the short side blade, the pre-compression block 42 moves horizontally and vertically under the action of the pre-compression drive 41. The pre-compression block 42 presses on the side blade outside the pinched corner position of the vacuum insulation plate, thereby facilitating the folding of the end side blade.

[0028] The pre-pressure drive component 41 includes a first pre-pressure drive cylinder 411 and a second pre-pressure drive cylinder 412. The first pre-pressure drive cylinder 411 is connected to the base 1 through a third connecting plate 413. The second pre-pressure drive cylinder 412 is connected to the first pre-pressure drive cylinder 411 through a fourth connecting plate 414 and is driven by the first pre-pressure drive cylinder 411 to move horizontally. The pre-pressure block 42 is connected to the second pre-pressure drive cylinder 412 and is driven by the second pre-pressure drive cylinder 412 to move vertically.

[0029] By setting a first pre-pressure drive cylinder 411 and a second pre-pressure drive cylinder 412, the pre-pressure block 42 can move horizontally and vertically under the action of the first pre-pressure drive cylinder 411 and the second pre-pressure drive cylinder 412, so that the pre-pressure block 42 presses on the edge leaf outside the corner position of the vacuum insulation plate.

[0030] In this embodiment, a leveling assembly 5 is also included. The leveling assembly 5 includes a leveling cylinder 51 and a leveling plate 52. The leveling cylinder 51 is disposed on the fourth connecting plate 414 and is arranged side by side with the second pre-pressure drive cylinder 412. The leveling plate 52 is connected to the leveling cylinder 51 and is driven by the leveling cylinder 51 to move vertically. In this way, the leveling plate 52 can level the edge leaf located outside the pinch corner position, thereby forming an indentation, which facilitates the folding of the end edge leaf.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
