Description

[0002] Vacuum insulation panel is a new type of high-efficiency insulation material based on the principle of vacuum insulation. It combines the advantages of vacuum insulation, microporous insulation and multi-layer insulation, and thus has outstanding insulation effect.

[0003] After the vacuum insulation panel is packaged, it is necessary to fold the edges around the vacuum insulation panel to make the vacuum insulation panel neat and easy to use. After the long side leaf of the vacuum insulation panel is flipped and folded, the short side leaf of the vacuum insulation panel needs to be flipped and folded. Before the short side leaf is flipped and folded, the connection position of the short side leaf and the long side leaf needs to be pinched to prevent the long side leaf from being exposed under the cover of the short side leaf after the short side leaf is folded.

DETAILED DESCRIPTION

[0050] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0051] like Figures 1 to 8 As shown, a corner pinching device of the present invention comprises a bottom frame seat 1, a conveying mechanism 2, a rolling mechanism 3 and a corner pinching mechanism 4; the conveying mechanism 2 is arranged on the bottom frame seat 1, the rolling mechanism 3 is arranged on the bottom frame seat 1 or on the conveying mechanism 2, and the corner pinching mechanism 4 is arranged on the bottom frame seat 1 and located at the end of the conveying mechanism 2. The corner pinching mechanism 4 comprises a first corner pinching mechanism 4a and a second corner pinching mechanism 4b, the first corner pinching mechanism 4a and the second corner pinching mechanism 4b are arranged opposite to each other, the first corner pinching mechanism 4a pinches the angle of one end side of the vacuum insulation panel, and the second corner pinching mechanism 4b pinches the angle of the other end side of the vacuum insulation panel.

[0052] In this way, the present invention relates to a corner pinching device. After the two long side leaves of the vacuum insulation panel are folded, the vacuum insulation panel is placed on the conveying mechanism 2 for conveying. Under the action of the rolling mechanism 3, the vacuum insulation panel is stably conveyed to the corner pinching station for corner pinching. When pinching, the forming drive 421 drives the forming plug-in 422 to move horizontally and vertically, so that the forming plug-in 422 is inserted into the connection position of the long side leaf and the short side leaf. The forming plug-in 422 moves to deform the connection position of the long side leaf and the short side leaf. Then the rolling drive 431 drives the first roller 432 and the second roller 433 to move along the surface of the side leaf. The first roller 432 is located on one side of the forming plug-in 422, and the second roller 433 is located on the other side of the forming plug-in 422, so that the connection position of the long side leaf and the short side leaf forms a crease, and the corner pinching of the vacuum insulation panel is completed. Therefore, the present invention realizes the automatic corner pinching action of the vacuum insulation panel by setting the conveying mechanism 2, the rolling mechanism 3 and the corner pinching mechanism 4, and improves the corner pinching efficiency.

[0053] Optionally, the conveying mechanism 2 includes a first conveying component 21 and a second conveying component 22. Figure 7 As shown, the first conveying assembly 21 includes a first conveying frame 211, a first conveying motor 212 and a first conveying belt 213. The first conveying frame 211 is arranged on the bottom frame seat 1, the first conveying motor 212 is arranged on the first conveying frame 211, and the first conveying belt 213 is driven to rotate by the first conveying motor 212. The second conveying assembly 22 includes a second conveying frame 221, a second conveying motor 222 and a second conveying belt 223. The second conveying frame 221 is arranged on the bottom frame seat 1, the second conveying frame 221 and the first conveying frame 211 are arranged side by side, the second conveying motor 222 is arranged on the second conveying frame 221, and the second conveying belt 223 is driven to rotate by the second conveying motor 222.

[0054] After the two long side leaves of the vacuum insulation panel are folded, the vacuum insulation panel is placed on the first conveyor belt 213 and the second conveyor belt 223. The first conveyor motor 212 and the second conveyor motor 222 drive the first conveyor belt 213 and the second conveyor belt 223 to rotate, thereby driving the vacuum insulation panel to be transported forward.

[0055] In this embodiment, it also includes an adjusting mechanism 5 for adjusting the distance between the first conveying assembly 21 and the second conveying assembly 22. The adjusting mechanism 5 includes an adjusting motor 51, an adjusting belt 52, a first adjusting seat and a second adjusting seat. The adjusting motor 51 is arranged on the bottom frame seat 1, the adjusting belt 52 is connected to the adjusting motor 51 and is driven to rotate by the adjusting motor 51, the first adjusting seat is arranged on the upper adjusting belt 52, the first adjusting seat is connected to the first conveying frame 211, the second adjusting seat is arranged on the lower adjusting belt 52, and the second adjusting seat is connected to the second conveying frame 221.

[0056] According to the vacuum insulation panels of different widths, the adjusting motor 51 drives the adjusting belt 52 to rotate, so that the first adjusting seat and the second adjusting seat are moved closer to or farther away from each other, thereby driving the first conveying assembly 21 and the second conveying assembly 22 to move closer to or farther away from each other, thereby adjusting the distance between the first conveying assembly 21 and the second conveying assembly 22.

[0057] In a preferred embodiment, it also includes a positioning mechanism 6, which includes a first positioning mechanism 61 and a second positioning mechanism 62 that are relatively arranged, the first positioning mechanism 61 is arranged on the first conveying frame 211, and the second positioning mechanism 62 is arranged on the second conveying frame 221; each positioning mechanism 6 includes a positioning cylinder 63 and a positioning plate 64, the positioning cylinder 63 is arranged on the conveying frame, the positioning plate 64 is connected to the positioning cylinder 63 and is driven to move by the positioning cylinder 63.

[0058] When the vacuum insulation panel with folded long side leaves is placed on the conveyor belt for transportation, the positioning plates 64 of the first positioning mechanism 61 and the second positioning mechanism 62 are close to each other, so as to position and align the two sides of the vacuum insulation panel, so as to facilitate the accurate transportation of the vacuum insulation panel to the position of the angle pinching mechanism 4.

[0059] Furthermore, the positioning plate 64 is in the shape of a long strip, and a guide block 641 is provided at the end of the positioning plate 64, and a first guide surface 6411 expanding outward is formed on the surface of the guide block 641; a guide plate 23 is provided at the ends of the first conveying frame 211 and the second conveying frame 221, and a second guide surface 231 expanding outward is formed on the surface of the guide plate 23. By providing the first guide surface 6411 and the second guide surface 231, when the vacuum insulation panel is conveyed, the end of the vacuum insulation panel can move along the first guide surface 6411 and the second guide surface 231, so that the vacuum insulation panel is easily input into the conveying mechanism 2 for rolling.

[0060] In a preferred embodiment, the rolling mechanism 3 includes a first rolling mechanism 31 and a second rolling mechanism 32. The first rolling mechanism 31 includes a first rolling frame 311, a first rolling cylinder 312 and a first rolling wheel 313. The first rolling frame 311 is arranged on the first conveying frame 211, the first rolling cylinder 312 is arranged on the first rolling frame 311, the first rolling wheel 313 and the first rolling cylinder 312 are driven to rise and fall, and the first rolling wheel 313 is located above the first conveyor belt 213; the second rolling mechanism 32 includes a second rolling frame 321, a second rolling cylinder 322 and a second rolling wheel 323, the second rolling frame 321 is arranged on the second conveyor frame 221, the second rolling cylinder 322 is arranged on the second rolling frame 321, the second rolling wheel 323 and the second rolling cylinder 322 are driven to rise and fall, and the second rolling wheel 323 is located above the second conveyor belt 223.

[0061] When the vacuum insulation panel is transported, the first rolling wheel 313 and the second rolling wheel 323 are pressed on the upper surface of the vacuum insulation panel, so that the vacuum insulation panel is more stable during transportation.

[0062] In this embodiment, the rolling wheel is connected to the rolling drive cylinder through a buffer mechanism 33. The buffer mechanism 33 includes a first buffer block, a buffer rod, a locking member, a second buffer block and a buffer spring. The first buffer block is connected to the rolling drive cylinder. One end of the buffer rod passes through the first buffer block and is connected to the locking member. The second buffer block is connected to the other end of the buffer rod. The buffer spring is sleeved on the buffer rod. The buffer spring is located between the first buffer block and the second buffer block. By setting the buffer mechanism 33, when the first rolling wheel 313 and the second rolling wheel 323 are pressed on the upper surface of the vacuum insulation panel, the buffer spring is compressed, thereby reducing the impact of the first rolling wheel 313 and the second rolling wheel 323 on the vacuum insulation panel when they descend, so that the barrier film of the vacuum insulation panel is not easily damaged.

[0063] There are multiple rolling wheels, which are distributed on both sides of the second buffer block. The rolling wheels can be against the long side leaves, and the conveyor belt rotates to realize the rolling of the rolling wheels along the long side leaves. Since the long side leaves of some vacuum insulation panels are relatively long, when the long side leaves are folded, some of the long side leaves are not attached or not tightly to the surface of the vacuum insulation panel, resulting in poor folding effect of the long side leaves of the vacuum insulation panel. The rolling wheels of the present invention roll along the long side leaves to realize rolling of the long side leaves of the vacuum insulation panel, so that some of the long side leaves that are not attached or not tightly are firmly attached to the surface of the vacuum insulation panel.

[0064] In a preferred embodiment of the present invention, the angle pinching mechanism 4 includes a base 41, a forming component 42 and a folding rolling component 43; the base 41 is arranged on the bottom frame seat 1, the forming component 42 includes a forming driving member 421 and a forming plug-in 422, the forming driving member 421 is arranged on the base 41, the forming plug-in 422 is connected to the forming driving member 421 and is driven to move by the forming driving member 421, the folding rolling component 43 includes a rolling driving member 431, a first roller 432 and a second roller 433, the rolling driving member 431 is arranged on the base 41, the first roller 432 is connected to the rolling driving member 431 and is driven to move by the forming driving member 421, the second roller 433 is connected to the rolling driving member 431 and is driven to move by the forming driving member 421, a deformation cavity is formed between the second roller 433 and the first roller 432, and the deformation cavity is arranged relative to the forming plug-in 422.

[0065] When in use, the vacuum insulation panel is transported to the angle pinching mechanism 4, and the forming drive 421 drives the forming plug-in 422 to move horizontally and vertically, so that the forming plug-in 422 is inserted into the connecting position of the long side leaf and the short side leaf. The forming plug-in 422 moves to deform the connecting position of the long side leaf and the short side leaf, and then the rolling drive 431 drives the first roller 432 and the second roller 433 to move along the surface of the side leaf, and the first roller 432 is located on one side of the forming plug-in 422, and the second roller 433 is located on the other side of the forming plug-in 422, so that a crease is formed at the connecting position of the long side leaf and the short side leaf, completing the angle pinching of the vacuum insulation panel.

[0066] In the prior art, there is a method of directly using a translation push plate and a pinching angle pressure plate to push and push to form a pinch angle at the connection position of the long side leaf and the short side leaf. The disadvantage is that when the pinching angle pressure plate is pressed down, the side leaf is squeezed, and the side leaf is randomly deformed. The connection position of the long side leaf and the short side leaf is easy to be laminated together, making the position thicker, affecting the folding of the side leaf. At the same time, the connection position of the long side leaf and the short side leaf is easy to be laminated together, which is easy to cause damage to the barrier film of the vacuum insulation panel, thereby affecting the thermal conductivity of the vacuum insulation panel. In response to this problem, the present invention adopts a first roller 432 and a second roller 433 to cooperate with a forming plug-in 422 to perform a pinch angle, so that the vacuum insulation panel forms a regular pinch angle that bulges upward, and there is no multi-layer lamination at the connection position of the long side leaf and the short side leaf, which is convenient for the subsequent end side leaf folding.

[0067] In this embodiment, the molding plug-in 422 is a molding ejector 4221, which is arranged obliquely downward. The molding ejector 4221 includes a connecting section 42211 and an inserting section 42212, one end of the connecting section 42211 is connected to the molding driving member 421, and the inserting section 42212 is connected to the other end of the connecting section 42211. The inner diameter of the inserting section 42212 gradually decreases from the direction close to the connecting section 42211 to the direction away from the connecting section 42211, and the outer surface of the inserting section 42212 forms an arc surface.

[0068] The forming push rod 4221 moves horizontally and vertically under the action of the forming driving member 421, so that the forming push rod 4221 is inserted into the connection position of the long side leaf and the short side leaf. Since the forming push rod 4221 is tilted downward, the forming push rod 4221 rises and the connection position of the long side leaf and the short side leaf is deformed tilted upward, so that the angle pinching effect is better. Since the inner diameter of the insertion section 42212 gradually decreases from the direction close to the connection section 42211 to the direction away from the connection section 42211, the outer surface of the insertion section 42212 forms an arc surface, which facilitates the insertion of the forming push rod 4221 into the connection position of the long side leaf and the short side leaf, and the insertion process will not cause damage to the side leaf of the vacuum insulation panel.

[0069] In this embodiment, the forming drive member 421 includes a first forming drive cylinder 4211 and a second forming drive cylinder 4212. The first forming drive cylinder 4211 is connected to the base 41 through a first connecting plate, and the second forming drive cylinder 4212 is connected to the first forming drive cylinder 4211 through a second connecting plate, and is driven to move horizontally by the first forming drive cylinder 4211. The forming plug-in 422 is connected to the second forming drive cylinder 4212, and is driven to move vertically by the second forming drive cylinder 4212. By providing the first forming drive cylinder 4211 and the second forming drive cylinder 4212, the horizontal and vertical displacements of the forming plug-in 422 are achieved under the action of the first forming drive cylinder 4211 and the second forming drive cylinder 4212.

[0070] In some embodiments, the molding insert 422 is a molding lever, which is rotatably disposed on the molding driving member 421. The molding lever in this embodiment can deform the connection position of the long side leaf and the short side leaf by rotating.

[0071] In a preferred embodiment, a pre-pressing assembly 44 is further included, and the pre-pressing assembly 44 includes a pre-pressing driving member 441 and a pre-pressing block 442. The pre-pressing block 442 is connected to the pre-pressing driving member 441 and is driven to move by the pre-pressing driving member 441. The pre-pressing block 442 is located on one side of the first roller 432. After the pinch angle is formed at the connection position of the long side leaf and the short side leaf, the pre-pressing block 442 moves horizontally and vertically under the action of the pre-pressing driving member 441, and the pre-pressing block 442 presses on the side leaf outside the pinch angle position of the vacuum insulation panel, so as to facilitate the folding of the end side leaf.

[0072] Specifically, the pre-stressing driving member 441 includes a first pre-stressing driving cylinder 4411 and a second pre-stressing driving cylinder 4412. The first pre-stressing driving cylinder 4411 is connected to the base 41 through a third connecting plate, and the second pre-stressing driving cylinder 4412 is connected to the first pre-stressing driving cylinder 4411 through a fourth connecting plate, and is driven to move horizontally by the first pre-stressing driving cylinder 4411. The pre-stressing block 442 is connected to the second pre-stressing driving cylinder 4412, and is driven to move vertically by the second pre-stressing driving cylinder 4412. By providing the first pre-stressing driving cylinder 4411 and the second pre-stressing driving cylinder 4412, the horizontal and vertical movements of the pre-stressing block 442 are realized under the action of the first pre-stressing driving cylinder 4411 and the second pre-stressing driving cylinder 4412, and the pre-stressing block 442 is pressed on the side leaf outside the pinching angle position of the vacuum insulation panel.

[0073] In a preferred embodiment of the present invention, a scraping assembly 45 is further included, and the scraping assembly 45 includes a scraping cylinder 451 and a scraping plate 452. The scraping cylinder 451 is arranged on the fourth connecting plate, and the scraping cylinder 451 is arranged side by side with the second pre-pressure driving cylinder 4412. The scraping plate 452 is connected to the scraping cylinder 451 and is driven to move vertically by the scraping cylinder 451. The scraping plate 452 can scrape along the edge blade located outside the pinching position, thereby forming an indentation, which is convenient for the end edge blade to be folded.

[0074] In this embodiment, an upper lift component 46 is also included. The upper lift component 46 includes an upper lift cylinder 461 and an upper lift plate 462. The upper lift cylinder 461 is set on the base 41. The upper lift plate 462 is connected to the upper lift cylinder 461 and is driven to rise and fall by the upper lift cylinder 461. The upper lift plate 462 is located below the pre-pressing block 442.

[0075] Before the scraping plate 452 is scraped flat and before the pre-pressing block 442 is pre-pressed, the upper cylinder 461 drives the upper plate 462 to rise so that the upper plate 462 is pressed against the lower surface of the edge blade, making it easier for the pre-pressing block 442 to press against the upper surface of the edge blade and for the scraping plate 452 to scrape flat along the upper surface of the edge blade.

[0076] In this embodiment, a positioning clamping mechanism 47 is also included, and the positioning clamping mechanism 47 includes a clamping cylinder 471 and a clamping plate 472. The clamping cylinder 471 is arranged on the base 41, and the clamping plate 472 is connected to the clamping cylinder 471 and driven to move by the clamping cylinder 471. The clamping plate 472 is located below the first roller 432 and the second roller 433. By providing the positioning clamping mechanism 47, before the angle is pinched, the clamping plate 472 is pressed against the side of the vacuum insulation panel under the action of the clamping cylinder 471, thereby preventing the vacuum insulation panel from being displaced during the angle pinching process of the vacuum insulation panel.

[0077] In some examples, a stop plate 48 is further included, the stop plate 48 is connected to the forming drive member 421 and is driven to move by the forming drive member 421, the stop plate 48 is located outside the forming insert 422, and the end of the stop plate 48 is higher than the end of the forming insert 422. When the forming insert 422 moves and inserts into the connection position of the long side leaf and the short side leaf, the stop plate 48 moves synchronously to the outside of the pinching position, and when the pinching position is deformed, the stop plate 48 prevents the side leaf outside the pinching position from excessively deforming.

[0078] In this embodiment, a propping piece 49 is also included. The propping piece 49 includes a fixed piece and an elastic piece. The propping fixed piece is arranged on the inner side of the first conveying frame 211 and / or the second conveying frame 221. The elastic piece and the fixed piece are integrally formed. The end of the elastic piece is initially higher than the surface of the first conveying belt 213. A propping assembly 410 is also included. The propping assembly 410 includes a propping cylinder 4101 and a propping block 4102. The propping cylinder 4101 is fixed on the inner side of the first conveying frame 211 and / or the second conveying frame 221. The propping block 4102 is connected to the propping cylinder 4101 and is driven to rise and fall by the propping cylinder 4101. The propping block 4102 is located on the outer side of the propping piece 49.

[0079] Under the action of the supporting sheet 49 and the supporting block 4102, the side leaf outside the pinching angle position is supported, so that it is convenient for the pre-pressing block 442 to press on the upper surface of the side leaf, and for the scraping plate 452 to scrape along the upper surface of the side leaf to form an indentation.

[0080] The present invention also discloses a method for pinching angles, which comprises the following steps:

[0081] Step one, place the vacuum insulation panel with the long side leaves folded and the short side leaves not folded on the working station of the angle pinching mechanism 4; step two, insert the forming plug-in 422 of the angle pinching mechanism 4 into the connecting position of the long side leaves and the short side leaves, and the forming plug-in 422 moves to cause the connecting position of the long side leaves and the short side leaves to produce an upward convex deformation; step three, the first roller 432 rolls from the outside to the inside along the surface of the vacuum insulation panel on one side of the forming plug-in 422, and at the same time, the second roller 433 rolls from the outside to the inside along the surface of the vacuum insulation panel on the other side of the forming plug-in 422, and under the action of the first roller 432, the second roller 433 and the forming plug-in 422, a crease is formed at the connecting position of the long side leaves and the short side leaves.

[0082] When the molding plug-in 422 is inserted into the connection position between the long side leaf and the short side leaf, the molding plug-in 422 moves to deform the connection position between the long side leaf and the short side leaf, and then the rolling drive 431 drives the first roller 432 and the second roller 433 to move along the surface of the side leaf, the first roller 432 is located on one side of the molding plug-in 422, and the second roller 433 is located on the other side of the molding plug-in 422, so that a crease is formed at the connection position between the long side leaf and the short side leaf, completing the angle pinching of the vacuum insulation panel.

[0083] Furthermore, before step 1, the vacuum insulation panel with the long side leaves folded and the short side leaves not folded is placed on the conveying mechanism 2; the positioning mechanism 6 positions the two sides of the vacuum insulation panel on the conveying mechanism 2, guides the vacuum insulation panel, and the rolling mechanism 3 descends and makes the rolling wheel abut against the upper surface of the vacuum insulation panel. The vacuum insulation panel is stably conveyed under the action of the rolling wheel and the conveying mechanism 2. In this way, under the action of the conveying mechanism 2, the positioning mechanism 6 and the rolling mechanism 3, the vacuum insulation panel is accurately conveyed to the angle pinching station for angle pinching operation.

[0084] In this embodiment, before the molded insert 422 is inserted into the connection position of the long side leaf and the short side leaf, the positioning clamping mechanism 47 positions the side of the vacuum insulation panel. By positioning the side of the vacuum insulation panel, displacement of the vacuum insulation panel is prevented during the angle pinching process.

[0085] Among them, the connection position of the long side leaf and the short side leaf is the pinching position, and the stop plate 48 is located above the outer side of the pinching position. When the molding plug-in 422 moves to cause the pinching position to deform upward, the stop plate 48 limits the long side leaf and the short side leaf to prevent excessive deformation of the short side leaf.

[0086] Furthermore, step 4 is included, in which the upper top plate 462 is raised, the upper top plate 462 is pressed under the outer side leaf of the angle pinching position, the pre-pressing block 442 is lowered, and the pre-pressing block 442 is pressed on the outer side leaf of the angle pinching position, so that the outer side leaf forms an indentation. Step 5 is also included, in which the upper top plate 462 is raised, the upper top plate 462 is pressed under the outer side leaf of the angle pinching position, the scraping plate 452 moves along the short side leaf, and the scraping mechanism flattens the short leaf that has been pinched and formed. In this way, it is easy to form an indentation, and after the indentation is formed, it is convenient to fold the side leaves at the front and rear ends of the vacuum insulation panel in the subsequent process.

[0087] In this embodiment, the angle pinching of the vacuum insulation panel is performed at room temperature. The vacuum insulation panel to be pinched has a length range of 400-2000 mm, a width range of 350-1000 mm, and a thickness range of 4-20 mm.
