Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of heat insulation board packaging edge folding equipment, and particularly to a soft page compression device of edge folding equipment. BACKGROUND

[0002] Vacuum insulation board is one of vacuum heat preservation materials, which can effectively avoid heat transfer caused by air convection, and greatly reduce the thermal conductivity. The structure of the vacuum insulation board usually includes a core material and a barrier film wrapped outside the core material. The core material is plate-shaped, usually composed of one or more materials with low thermal conductivity, such as glass fiber, polyester fiber and other materials with very low thermal conductivity. The barrier film usually adopts a pre-made bag-shaped barrier bag to wrap the core material and place a getter in the bag to ensure the stability of the interior after vacuumizing. Then the vacuumized core material wrapped in the bag is ready for vacuumizing operation. After vacuumizing, the vacuum insulation board is completed.

[0003] After the core material is wrapped with the barrier bag and vacuumized, due to the effect of external atmospheric pressure, the barrier bag will be flattened around the core material, forming soft pages around the core material. There are usually two opposite soft pages and four annularly connected soft pages. In order to avoid the influence of soft pages on the transportation and installation of vacuum insulation boards, and to avoid the damage of soft pages affecting the sealing, manual folding of soft pages is usually required, and then glue is used to fix them tightly on the heat insulation board. However, manual folding is labor-intensive and has low production efficiency.

[0004] Therefore, various automatic edge folding machines appear on the market, which can automatically fold the soft pages. However, most of the edge folding machines can only fold and press the four-edge soft pages 21 of the rectangular heat insulation board 1, and cannot perform good pressing operation on the heat insulation board 1 with bevels (see Figure 1 ). Because the soft pages 21 of the bevels are triangular after being turned over, the part of the existing push block 3 extending out of the triangular soft pages 21 will scratch the glue (see Figure 2 ) pre-coated on the surface of the heat insulation board 1, affecting the use of the existing push block 3 and the subsequent gluing effect of other soft pages 21, resulting in low product yield. INVENTION CONTENTS

[0005] The utility model aims to provide a soft page compression device of edge folding equipment, which can realize the pressing operation of the bevels of the heat insulation board, has high production efficiency and high product yield.

[0006] In order to achieve the above purpose, the solution of the utility model is as follows:

[0007] A soft page compression device of edge folding equipment, comprising a device support, a push mechanism and a flattening mechanism.

[0008] The device support comprises two left and right parallel support members, and a folding area is formed between the two support members;

[0009] The flattening mechanism comprises at least one linear module and two connecting bearings. The linear module extends forward and backward and is arranged on one of the support members. The two connecting bearings are arranged on the two support members respectively, and one of the connecting bearings is arranged on the top of the sliding seat of the linear module on one of the support members.

[0010] The pushing mechanism comprises a pushing fixed plate, a pushing cylinder and a pushing block. The left and right ends of the pushing fixed plate are arranged above the two support members respectively, and the two ends of the pushing fixed plate are respectively provided with bearing holes and sliding long grooves for the connecting bearings. The support member on which the sliding long groove end of the pushing fixed plate is arranged is provided with the linear module. The pushing cylinder is installed on the pushing fixed plate and drives the pushing block below the pushing fixed plate to move up and down.

[0011] The sliding seat of the linear module reciprocally moves to drive the connecting bearings to reciprocally slide in the sliding long grooves, thereby controlling the overall deflection movement of the pushing mechanism.

[0012] Further, the length of the pushing block can be extended and retracted along the length direction of the pushing fixed plate.

[0013] Further, the pushing mechanism further comprises a pushing movable plate and two extension components. The pushing block comprises two pushing plates which are distributed left and right and arranged forward and backward. The pushing plates are respectively slidably connected to the pushing movable plate and are controlled by the extension components to reciprocally move left and right. The relative separation or approach of the two pushing plates of the pushing block controls the extension or shortening of the overall length of the pushing block. The pushing movable plate is connected to the power end of the pushing cylinder and is driven by the pushing cylinder to move the pushing block composed of the two pushing plates up and down.

[0014] Further, the pushing movable plate is arranged parallel below the pushing fixed plate. The middle part of the top surface of the pushing movable plate is connected to the lower end power end of the pushing cylinder fixed in the middle part of the pushing fixed plate. The two sides of the pushing movable plate are respectively connected to guide rods, and the upper ends of the guide rods are slidably connected through the linear bearings on the two sides of the pushing fixed plate.

[0015] Further, the pushing movable plate is arranged parallel below the pushing fixed plate. The middle part of the top surface of the pushing movable plate is connected to the lower end power end of the pushing cylinder fixed in the middle part of the pushing fixed plate. The two sides of the pushing movable plate are respectively connected to guide rods, and the upper ends of the guide rods are slidably connected through the linear bearings on the two sides of the pushing fixed plate. Further, the bottom of the pushing movable plate and the top of the pushing plate are slidably connected and matched through a pushing sliding rail and a plurality of pushing sliding seats. The extension component comprises an extension motor, an extension screw rod, an extension screw rod nut and a nut fixed seat. The extension motor is connected to the pushing movable plate. One end of the extension screw rod is connected to the extension motor. The extension screw rod nut is sleeved on the extension screw rod, and the extension screw rod nut is installed on the top of the nut fixed seat. The bottom of the nut fixed seat is connected and fixed to the pushing plate. The extension motor drives the extension screw rod to rotate, controls the reciprocating movement of the extension screw rod nut, and drives the reciprocating movement of the nut fixed seat and the pushing plate.

[0016] Furthermore, the top left front part and right rear part of the push-pressing movable plate are respectively provided with a number of push-pressing slides spaced left and right; the top of the push-pressing plate is provided with push-pressing slide rails extending left and right, and the push-pressing slide rails are respectively slidably connected with each push-pressing slide on the left front part and right rear part.

[0017] Furthermore, the leveling mechanism includes two linear modules; both linear modules extend forward and backward and are respectively disposed on the top of two support members, while two connecting bearings are respectively disposed on the top of the sliding seats of the two linear modules and then cooperate with the bearing holes and sliding grooves respectively.

[0018] Furthermore, the linear module includes a guide rail, a sliding seat, a linear lead screw, and a linear motor; the guide rail extends front and rear; the linear lead screw is arranged parallel above the guide rail, and its front and rear ends are rotatably connected to the front and rear upright plates respectively; the sliding seat is a lead screw sliding seat, which is sleeved on the linear lead screw, and the bottom of the sliding seat slides on the guide rail; the linear motor is driven by the linear lead screw and is used to drive the linear lead screw to rotate, so as to drive the sliding seat to reciprocate along the guide rail.

[0019] Furthermore, the peripheral wall of the connecting bearing is recessed with an annular groove; the side wall of the bearing hole protrudes with a flange that fits into the corresponding annular groove of the connecting bearing; the side wall of the sliding groove protrudes with a groove flange that extends and limits the corresponding annular groove of the connecting bearing.

[0020] Furthermore, the device support also includes a front support rod and a rear support rod, with the front support rod connected to the front ends of the two support members and the rear support rod connected to the rear ends of the two support members.

[0021] After adopting the above technical solution, when using the soft-sheet pressing device to automatically fold and press the insulation board, firstly, the vacuum-sealed insulation board and barrier bag can be transported to the folding work area by a robot or conveyor belt, etc., and the soft sheet formed after vacuuming the barrier bag is lifted by a lifting device, etc., and then flipped to stick against the top surface of the insulation board. When pressing the soft sheet with the slanted edge, the slanted edge of the insulation board can be controlled to be parallel to the initial state of the pressing mechanism. Then, the pressing cylinder drives the pressing block to press down and initially stick against the insulation board. The hot plate's soft sheet is then moved back and forth by sliding the sliding seat at the end of the sliding groove. At the same time, the connecting bearing on the sliding seat can slide within the sliding groove, and the connecting bearing at the bearing hole end rotates, causing the pressing block to tilt. This allows the linear module to drive the pressing mechanism to oscillate, so that the pressing block can cover and press along the folded triangular soft sheet with a fan-shaped area. This avoids the pressing block extending out of the triangular soft sheet area and scratching the glue, and also ensures the pressing effect, improves the pressing power, and increases the yield of insulation board production.

[0022] Therefore, the pushing block moving in the deflection manner can gradually push the triangular soft page from outside to inside to tightly adhere and fix on the top surface of the heat insulation plate, so as to realize the soft page pressing and fixing of the heat insulation plate with the inclined angle; and the top surface of the heat insulation plate is usually coated with glue in advance, so that the bottom surface of the soft page can be adhered and fixed on the glue on the top surface of the heat insulation plate when the pushing block pushes the soft page, thereby realizing the pressing and fixing operation.

[0039] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0040] As shown in the drawings, Figures 3 to 6 The soft page pressing device 10 of the folding equipment in the embodiment is part of the folding equipment, which can cooperate with other devices to realize automatic pressing and fixing of the bevel soft page of the bevel angle heat insulation plate 1.

[0041] As shown in the drawings, Figures 3 to 5 The soft page pressing device 10 includes a device support 100, a pushing mechanism 200 and a straightening mechanism 300.

[0042] The device support 100 includes two left and right parallel and spaced support members 110, a front support rod 120 and a rear support rod 130. The front support rod 120 is connected to the front ends of the two support members 110, and the rear support rod 130 is connected to the front and rear ends of the two support members 110. In this way, the structural stability of the device support 100 can be ensured.

[0043] The straightening mechanism 300 includes two linear modules 310 and two connecting bearings 320. The two linear modules 310 are arranged on the top of the two support members 110 and are parallel to each other. The area between the two linear modules 310 is a folding work area 400. The two connecting bearings 320 are arranged on the top of the sliding seats 311 of the two linear modules 310.

[0044] In this embodiment, the linear module 310 is taken as an example of a screw rod structure, and includes a guide rail 312, a sliding seat 311, a linear screw rod 313, and a linear motor 314.

[0045] The guide rail 312 extends forward and backward, and can be fixed to the top of the support 110; that is, the two supports 110 of the device support 100 are arranged at the bottom of the two linear modules 310; the linear screw rod 313 is arranged in parallel above the guide rail 312, and the front and rear ends of the linear screw rod 313 are respectively rotationally connected to the front and rear vertical plates 140; the sliding seat 311 is a screw rod sliding seat 311, and is sleeved on the linear screw rod 313, and the bottom of the sliding seat 311 is slidably connected to the guide rail 312; the linear motor 314 is drivingly connected to the linear screw rod 313, and is used to drive the linear screw rod 313 to rotate, so as to drive the sliding seat 311 to reciprocatingly move along the guide rail 312. The linear motor 314 can be a stepping motor, and can be installed below the guide rail 312, and can be drivingly connected to the linear screw rod 313 through the two transmission wheels 315 and the belt 316. Of course, other transmission connection modes can be adopted.

[0046] The pushing mechanism 200 includes a pushing fixed plate 210, a pushing cylinder 220, and a pushing block 230; the pushing fixed plate 210 is arranged above the sliding seat 311 of the linear module 310 on the two supports 110, and the two ends of the pushing fixed plate 210 are respectively provided with bearing holes 211 and sliding long grooves 212 for the bearing 320 to pass through; the pushing cylinder 220 is installed on the pushing fixed plate 210, and drives the pushing block 230 below the pushing fixed plate 210 to move up and down;

[0047] The sliding seats 311 of the two linear modules 310 move synchronously or asynchronously, so as to drive the pushing mechanism 200 to move synchronously or asynchronously along the guide rail of the linear module 310.

[0048] Therefore, when the soft page pressing device 10 is used to automatically fold and press the thermal insulation plate 1, first, the thermal insulation plate 1 and the barrier bag 2 after being vacuumized can be conveyed into the folding working area 400 by a mechanical hand or a conveying belt (not shown in the figure), and the soft page 21 formed by the barrier bag 2 after being vacuumized is lifted and then turned over to be attached to the top surface of the thermal insulation plate 1 (see Figure 1As shown, this part can adopt the prior art, then drive the pushing cylinder 220 to drive the pushing block 230 to press and push the soft page 21 preliminarily attached to the heat insulation plate 1, and then drive the linear module 310 to drive the pushing mechanism 200 to move as a whole, so that the pushing block 230 can gradually push the soft page 21 from outside to inside to make it tightly attached and fixed on the top surface of the heat insulation plate 1, and the top surface of the heat insulation plate 1 is usually coated with glue or tape in advance, so that when the pushing block 230 pushes the soft page 21, the bottom surface of the soft page 21 can be adhered and fixed on the glue on the top surface of the heat insulation plate 1, thereby realizing the pressing and fixing operation.

[0049] Specifically, some heat insulation plates 1 have right angles and oblique angles, that is, they have not only right angle edges but also oblique edges. When pressing the soft page 21 of the right angle edge, the right angle edge of the heat insulation plate 1 can be controlled to be parallel to the pushing mechanism 200 in the initial state, and then the sliding seats 311 of the two linear modules 310 are synchronously moved to synchronously move the pushing block 230 of the pushing mechanism 200 to press and fix the soft page 21 folded into a rectangle, so that the pushing block 230 can completely cover all areas of the soft page 21.

[0050] When pressing the soft page 21 of the oblique edge, referring to Figure 7 , the oblique edge of the heat insulation plate 1 can be controlled to be parallel to the pushing mechanism 200 in the initial state, and then the sliding seats 311 of the two linear modules 310 are moved asynchronously, for example, the sliding seat 311 at the end of the sliding long groove 212 is moved first, and the sliding seat 311 at the end of the bearing hole 211 is not moved, so that the pushing block 230 can be tilted, that is, the pushing mechanism 200 can drive the pushing block 230 to realize the deflection movement, and the pushing block 230 can cover and push the soft page 21 folded into a triangle along the oblique edge, thereby avoiding the pushing block 230 extending out of the area of the soft page 21 to scratch the glue, and ensuring the pressing and fixing effect, improving the pressing and fixing success rate, and improving the production yield of the heat insulation plate 1.

[0051] In the embodiment, the flattening mechanism 300 can realize synchronous movement or deflection movement of the pushing mechanism 200 by arranging two linear modules 310. Therefore, the deflection movement of the pushing mechanism 200 can also be realized by arranging only one linear module 310 and simplifying the flattening mechanism 300.

[0052] Specifically, the flattening mechanism 300 comprises at least one linear module 310 and two connecting bearings 320; the linear module 310 can be arranged on the left support 110, and the two connecting bearings 320 are arranged on the two supports 110 respectively, and the left connecting bearing 320 is arranged on the top of the sliding seat 311 of the linear module 310 of the left support 110; the right connecting bearing 320 can be directly rotatably installed on the top of the right support 110 (not shown in the figure).

[0053] The end of the sliding long groove 212 of the push fixed plate 210 is arranged on the linear module 310 of the left support 110 and passes through the left connecting bearing 320; the sliding seat 311 of the linear module 310 reciprocatingly moves to drive the left connecting bearing 320 to reciprocatingly slide in the sliding long groove 212, thereby controlling the overall deflection movement of the pushing mechanism 200.

[0054] Specifically, by making the sliding seat 311 at the end of the left sliding long groove 212 slide forward and backward, the connecting bearing 320 on the left sliding seat 311 can slide in the sliding long groove 212, and the connecting bearing 320 at the end of the right bearing hole 211 rotates in place, so that the pushing block 230 is inclined, that is, the left linear module 310 can drive the pushing mechanism 200 to move in deflection, thereby realizing the pressing and fixing of the inclined soft page of the inclined angle heat insulation plate.

[0055] In this embodiment, the sliding seat 311 of the linear module 310 reciprocatingly slides in the front and back directions along the guide rail 312. The length of the pushing block 230 can be stretched and contracted along the length direction of the push fixed plate 210.

[0056] Specifically, the pushing mechanism 200 can further comprise a push movable plate 240 and two telescopic assemblies 250; the pushing block 230 comprises two push plates 231 distributed left and right and arranged front and back; the push plates 231 are respectively slidably connected to the push movable plate 240 and reciprocatingly move left and right under the control of the telescopic assemblies 250; the two push plates 231 of the pushing block 230 relatively separate or approach to control the overall length of the pushing block 230 to be elongated or shortened; the push movable plate 240 is connected with the power end 221 of the push cylinder 220 and is driven by the push cylinder 220 to move up and down with the pushing block 230 composed of the two push plates 231.

[0057] Therefore, referring to Figures 6 to 9When the soft page 21 with bevel edge is pressed by the soft page pressing device 10, the sliding seat 311 at the end of the sliding long groove 212 drives the whole pushing mechanism 200 to deviate and drives the end of the sliding long groove 212 to continue to move backward, and the sliding seat 311 at the end of the bearing hole 211 can also move backward synchronously from the original state. At this time, in order to avoid the pushing block 230 extending out of the triangular soft page 21 area and scratching the glue, the pushing plate 231 can be controlled to move by the telescopic assembly 250, so that the length of the pushing block 230 is shortened. Therefore, through the forward and backward movement of the two sliding seats 311, combined with the telescopic control of the telescopic assembly 250 on the pushing block 230, the pressing and fixing of all areas of the triangular soft page 21 can be realized, and the pressing effect is improved.

[0058] In the embodiment, the pushing movable plate 240 is arranged in parallel below the pushing fixed plate 210; the middle part of the top surface of the pushing movable plate 240 is connected with the lower end power end 221 of the pushing cylinder 220 fixed in the middle part of the pushing fixed plate 210; and the two sides of the pushing movable plate 240 can be respectively connected with guide rods 241, and the upper ends of the guide rods 241 slide through the linear bearings 213 on the two sides of the pushing fixed plate 210. Therefore, the pushing movable plate 240 and the corresponding pushing block 230 can be stably and reliably driven by the pushing cylinder 220 to move up and down, so as to ensure the pressing degree.

[0059] In the embodiment, the bottom of the pushing movable plate 240 and the top of the pushing plate 231 are connected by the pushing sliding rail 232 and the pushing sliding seat 242; the telescopic assembly 250 includes a telescopic motor 251, a telescopic screw rod 252, a telescopic screw rod nut 253 and a nut fixed seat 254; the telescopic motor 251 is connected to the pushing movable plate 240; one end of the telescopic screw rod 252 is connected to the telescopic motor 251; the telescopic screw rod nut 253 is sleeved on the telescopic screw rod 252, and the telescopic screw rod nut 253 is installed on the top of the nut fixed seat 254; the bottom of the nut fixed seat 254 is connected and fixed with the pushing plate 231; the telescopic motor 251 drives the telescopic screw rod 252 to rotate, controls the telescopic screw rod nut 253 to move back and forth, drives the nut fixed seat 254 and the pushing plate 231 to move back and forth, so as to realize the sliding control of the pushing plate 231.

[0060] Specifically, the top left front part and the right rear part of the pushing movable plate 240 are respectively provided with a plurality of left and right interval pushing sliding seats 242, the top of the pushing plate 231 is provided with a left and right extending pushing sliding rail 232, and the pushing sliding rail 232 is respectively connected with the pushing sliding seat 242 on the left front part and the right rear part.

[0061] Meanwhile, the right end of the left pushing plate 231 is always overlapped with the left end of the right pushing plate 231, so that the pushing block 230 composed of the two pushing plates 231 is not disconnected in the middle, and the pushing effect is good. In addition, the moving range of the pushing plate 231 can be controlled and limited by setting sensors, travel switches and the like, and this part can adopt the prior art, which will not be described here.

[0062] In the embodiment, the pushing block 230 is realized by the telescopic cooperation of the two pushing plates 231, and of course other modes can also be adopted, which are not limited to this.

[0063] For example Figure 4 and Figure 10 As shown in the drawings, in the embodiment, the peripheral wall of the connecting bearing 320 can be concavely provided with an annular groove 321; the side wall of the bearing hole 211 can be protrudingly provided with a hole flange 214 embedded in the annular groove 321 of the corresponding connecting bearing 320; and the side wall of the sliding long groove 212 is protrudingly provided with a long groove flange 215 extending and limiting the annular groove 321 of the corresponding connecting bearing 320. In this way, the pushing fixed plate 210 and the two connecting bearings 320 are conveniently limited and cooperated, and the respective rotation and sliding effects are not affected.
