Description

Technical Field

[0001] This invention relates to the field of bonding equipment. More specifically, this invention relates to a polyurethane cold storage panel bonding device. Background Technology

[0002] The current manufacturing process for polyurethane cold storage panels involves first folding both ends of a color-coated steel sheet to create a U-shaped cross-section. Then, adhesive is applied to the inner wall of the steel sheet (including the folded edges and inner bottom). Finally, polyurethane prepolymer is sprayed onto the adhesive-coated steel sheet. After a period of time, the polyurethane prepolymer bubbles to form a polyurethane layer, providing insulation. In these steps, the adhesive is typically applied manually to the folded steel sheet, and existing bonding equipment usually only works on flat surfaces, lacking a specific bonding device for the U-shaped cross-section of the folded steel sheet. Summary of the Invention

[0003] One object of the present invention is to solve at least the above-mentioned problems and to provide a polyurethane cold storage panel bonding device, which can apply adhesive to the inner wall of the folded color steel panel, avoiding manual adhesive application and improving adhesive application efficiency.

[0004] To achieve these objectives and other advantages according to the present invention, a polyurethane cold storage panel bonding device is provided for applying adhesive to a color steel panel, wherein the two ends of the color steel panel are folded upwards to form a structure with a U-shaped cross-section, comprising:

[0005] A conveying assembly for conveying the color steel sheet;

[0006] The adhesive application assembly includes a vertical raw material tank, a horizontal adhesive dispensing box, and a pressure device. The raw material tank has an open top and a piston inside. Below the piston, the raw material tank serves as an adhesive storage area. The adhesive dispensing box is connected to the adhesive storage area. One pair of opposite side walls of the adhesive dispensing box are mounting walls. Both the mounting walls and the bottom wall of the adhesive dispensing box are provided with adhesive dispensing channels. Each adhesive dispensing channel is detachably equipped with a blocking plate. Each dispensing channel has brush bristles on one side. The mounting walls correspond to the two folded side walls of the color steel plate. The bottom of the adhesive dispensing box corresponds to the inner bottom wall of the color steel plate. The pressure device is used to push the piston to move in order to squeeze the adhesive and thus cause the adhesive to be squeezed out from the adhesive dispensing channel onto the corresponding color steel plate wall. The brush bristles apply the squeezed adhesive.

[0007] Preferably, one end of the brush bristles is connected to the inner wall of the glue dispensing box on one side of the glue dispensing channel inside the glue dispensing box, and the other end extends out of the corresponding glue dispensing channel.

[0008] Preferably, the dispensing box includes a pair of mirror-symmetrical moving tubes and a middle tube. The opposite ends of the pair of moving tubes are closed to form the pair of mounting walls. The open ends of the pair of moving tubes are respectively sealed and fitted onto both ends of the middle tube, and the moving tubes slide along the middle tube. The middle tube is connected to the glue storage area. It also includes a pair of opposing clamping auxiliary components and a driving component. The clamping auxiliary components include clamping plates, auxiliary blocks, horizontal mounting plates, and a pair of vertical connecting rods. An auxiliary block is detachably provided on each of the opposite side walls of the pair of clamping plates. The pair of auxiliary blocks are respectively provided on both sides of the color steel plate. Each clamping plate has a mounting plate at its top and a connecting rod at its bottom. The two pairs of connecting rods correspond to a pair of moving tubes. The other ends of the pair of connecting rods are respectively provided on both sides of the corresponding moving tube and are fixedly connected to the side wall of the corresponding moving tube. The driving component drives the pair of clamping plates to move synchronously towards / away from each other.

[0009] The two opposing inner walls of the dispensing channel are a first inner wall and a second inner wall. The first inner wall is arranged along the length of the dispensing channel. One end of the bristles of the intermediate tube is located on the first inner wall of the dispensing channel corresponding to it, and the other end extends out of the dispensing channel. One end of the bristles of the moving tube is located on the second inner wall of the dispensing channel corresponding to it, and the other end extends out of the dispensing channel.

[0010] Preferably, brush bristles are provided on both inner walls of the adhesive dispensing channel where the mounting wall is located.

[0011] Preferably, the conveying assembly has a pair of vertical support columns on both sides, and mounting blocks are provided on the extended ends of the pair of support columns, with the raw material tank mounted on top of the mounting blocks.

[0012] Preferably, the piston has a vertical piston rod, and the mounting block has a vertical mounting post; the pressure-applying component includes a drive motor, a gear, a support rod, a vertical rack, and a horizontal support plate. The drive motor is located on the upper part of the mounting post. The output end of the drive motor is coaxially fixed to the gear through the support rod. The gear meshes with the rack. The bottom of the rack is detachably connected to the piston rod. The rack is slidably mounted on the support plate, and the support plate is fixedly connected to the mounting post.

[0013] Preferably, each of the opposite sidewalls of the pair of clamps is provided with a slot, and the auxiliary block is provided with a locking block that matches the slot. The auxiliary block is detachably connected to the clamps through the locking block and the slot.

[0014] The present invention has at least the following beneficial effects:

[0015] This invention provides an adhesive bonding device for applying adhesive to the inner wall of a color steel plate folded at both ends to form a U-shaped cross-section. The device includes a conveying assembly, a raw material tank, a glue dispensing box, a pressure applying component, a piston, a blocking plate, brush bristles, and a glue dispensing channel. In use, the blocking plate is inserted into the glue dispensing channel, and then glue is added to the raw material tank until the glue dispensing box is full. Next, the piston is inserted into the raw material tank. At this point, the pressure applying component is activated, causing the piston to move downwards, squeezing out the glue. The glue then flows out of the glue dispensing channel and adheres to the brush bristles. Once the glue dispensing from the brush bristles is stable (this can be tested with a color steel plate initially), the conveying assembly is activated. As the conveying assembly moves, the color steel plate moves, and the brush bristles apply adhesive to the inner wall of the color steel plate. This effectively applies adhesive to the inner wall of the color steel plate, avoiding the low efficiency caused by manual application.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0028] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0029] like Figure 1-9 As shown, the present invention provides a polyurethane cold storage panel bonding device, comprising:

[0030] For applying adhesive to the color steel sheet 7, wherein the two ends of the color steel sheet 7 are folded upwards to form a structure with a U-shaped cross-section, including:

[0031] A conveying assembly for conveying the color steel plate 7;

[0032] The adhesive application assembly includes a vertical raw material tank 5, a horizontal adhesive dispensing box, and a pressure device. The raw material tank 5 has an open top and a piston 501 inside. Below the piston 501, the raw material tank 5 is an adhesive storage area. The adhesive dispensing box is connected to the adhesive storage area. One pair of opposite side walls of the adhesive dispensing box are mounting walls. Both the mounting walls and the bottom wall of the adhesive dispensing box are provided with adhesive dispensing channels. Each adhesive dispensing channel is detachably equipped with a blocking plate. Each adhesive dispensing channel has bristles on one side. The mounting walls correspond to the two folded side walls of the color steel plate 7. The bottom of the adhesive dispensing box corresponds to the inner bottom wall of the color steel plate 7. The pressure device is used to push the piston 501 to move so as to squeeze the adhesive and thus cause the adhesive to be squeezed out from the adhesive dispensing channel onto the corresponding wall of the color steel plate 7. The bristles apply the squeezed adhesive.

[0033] In the above technical solution, the two ends of the color steel plate 7 are folded upwards at 90 degrees to form a structure with a U-shaped cross-section. The color steel plate 7 is a U-shaped groove structure. The color steel plate 7 includes two folded side walls and a bottom wall located between the two side walls. The conveying assembly includes an installation platform 2 and a conveyor belt mounted on the installation platform 2. The conveyor belt is driven to rotate by a first drive motor 6. Multiple pairs of support columns 3 are spaced apart along the conveying direction on the installation platform 2, and each pair of support columns 3 is located on both sides of the conveyor belt 1. A piston 501 is sealed and slidably mounted inside the raw material tank 5. The top of the raw material tank 5 is open so that the piston 501 can be removed from the open. The glue dispensing box is horizontally set and is mounted on the support column 3 by a bracket. In use, it is placed between the two folded edges of the color steel plate 7. The length of the glue dispensing box is along the width direction of the bottom wall of the color steel plate 7. Figure 1 The glue dispensing box is positioned in a left-right direction. Its two opposite side walls are mounting walls, corresponding to the two side walls of the color steel plate 7. Each mounting wall and the bottom of the glue dispensing box have a through-hole glue dispensing channel. The glue dispensing channel at the bottom of the glue dispensing box is positioned along its length, preferably with open ends. The glue dispensing channel on the mounting wall is positioned along its height, also preferably with open ends. The length of the glue dispensing box is slightly smaller than the width of the bottom wall of the color steel plate 7, such as 2-4 mm less. Each glue dispensing channel has brush bristles on one side, arranged along the length of the dispensing channel to coat the color steel plate 7. The brush bristles can be attached to the side edge of the brush bristles, or one end of the brush bristles can be connected to the inner wall of the glue dispensing channel, and the other end can extend out of the glue dispensing channel. The blocking plate blocks the glue dispensing channel so that the glue dispensing box is filled with glue initially. The blocking plate can be a flat plate with a sealing layer on its surface. When in use, the blocking plate needs to be removed (the blocking plate is not shown in the figure). The bottom of the raw material tank 5 is connected to the top of the glue dispensing box through the connecting pipe 20. The pressure applying component can be a linear motor. The extension end of the linear motor is detachably connected to the piston 501. When the extension end of the linear motor extends or retracts, it drives the piston 501 to extend or retract, thereby squeezing the glue and causing the glue to flow out from the glue dispensing channel.

[0034] In this technical solution, during use, the blocking plate is inserted into the glue dispensing channel, and then glue is added into the raw material tank 5 until the glue dispensing box is full. Then, the piston 501 is inserted into the raw material tank 5. At this time, the pressure applying component is activated, which drives the piston 501 to move downward, squeezing the glue. Finally, the glue flows out from the glue dispensing channel and adheres to the brush bristles. When the glue dispensing from the brush bristles is stable (it can be tested with the color steel plate 7 in the early stage), the conveying component is activated. As the conveying component moves, the color steel plate 7 moves, and the brush bristles coat the inner wall of the color steel plate 7. After coating, the color steel plate 7 can be sprayed with polyurethane.

[0035] The beneficial effect of adopting this technical solution is that, by setting up a conveying component, a raw material tank 5, a glue dispensing box, a pressure application component, a piston 501, a blocking plate, brush bristles, and a glue dispensing channel, an adhesive device is provided for applying glue to the inner wall of a color steel plate 7 that is folded at both ends to form a U-shaped cross section. This device can effectively apply glue to the inner wall of the color steel plate 7, avoiding the low efficiency caused by manual brushing.

[0036] In another technical solution, one end of the brush bristles is connected to the inner wall of the glue outlet channel, and the other end extends out of the corresponding glue outlet channel. The beneficial effect of this technical solution is that this design allows the glue to come into direct contact with the brush bristles when passing through the glue outlet channel, so that the brush bristles can quickly adhere to the glue.

[0037] In another technical solution, the dispensing box includes a pair of mirror-symmetrical movable tubes 8 and an intermediate tube 9. The opposite ends of the pair of movable tubes 8 are closed to form the pair of mounting walls. The open ends of the pair of movable tubes 8 are respectively sealed and fitted onto both ends of the intermediate tube 9, and the movable tubes 8 slide along the intermediate tube 9. The intermediate tube 9 is connected to the glue storage area. It also includes a pair of opposing clamping auxiliary components and a driving component. The clamping auxiliary components include a clamping plate 12, an auxiliary block 13, a horizontal mounting plate 11, and a pair of vertical connecting rods 10. Each pair of clamping plates 12 has an auxiliary block 13 detachably mounted on each of its opposite side walls. The pair of auxiliary blocks 13 are respectively located on both sides of the color steel plate 7. Each clamping plate 12 has a mounting plate 11 at its top and a connecting rod 10 at its bottom. The two pairs of connecting rods 10 correspond to a pair of moving tubes 8. The other ends of the pair of connecting rods 10 are respectively located on both sides of the corresponding moving tube 8 and are fixedly connected to the side wall of the corresponding moving tube 8. The driving component drives the pair of clamping plates 12 to move synchronously towards / away from each other.

[0038] The two opposing inner walls of the glue dispensing channel are a first inner wall and a second inner wall. The first inner wall is arranged along the length of the glue dispensing channel. One end of the bristles of the intermediate tube 9 is located on the first inner wall of the glue dispensing channel corresponding to it, and the other end extends out of the corresponding glue dispensing channel. One end of the bristles of the moving tube 8 is located on the second inner wall of the glue dispensing channel corresponding to it, and the other end extends out of the corresponding glue dispensing channel.

[0039] In the above technical solution, the glue dispensing box is located in the middle of the conveyor belt 1; the glue dispensing box includes a central tube 9 located in the middle and a pair of movable tubes 8 sleeved at both ends of the central tube 9. The pair of movable tubes 8 are mirror-symmetrical, and the opposite ends of the pair of movable tubes 8 are closed to form the mounting wall. A sealing layer 22 is provided on the outer wall of the central tube 9 so that the movable tubes 8 can slide in a sealed manner along the central tube 9. A horizontal limiting post 19 is provided on the inner top wall of each movable tube 8. A pair of limiting grooves 21 adapted to the pair of limiting posts 19 are respectively provided on the outer top wall of the central tube 9. The limiting posts 19 are inserted into the limiting grooves 21 to realize the sealed and limited sliding of the movable tubes 8 along the central tube 9. One end of the connecting pipe 20 is connected to the raw material tank 5 and the other end is connected to the central tube 9. The glue dispensing channel of the movable tube 8 is the first glue dispensing channel 17, the glue dispensing channel of the central tube 9 is the third glue dispensing channel 25, and the glue dispensing channel on the mounting wall is... The second glue outlet channel 23 has brush bristles 18 on the first glue outlet channel 17, brush bristles 24 on the second glue outlet channel 23, and brush bristles 26 on the third glue outlet channel 25. The clamping plates 12 are vertically arranged, with a pair of clamping plates 12 corresponding to a pair of auxiliary blocks 13. The pair of auxiliary blocks 13 are respectively disposed on both sides of the color steel plate 7, and are detachably mounted on the corresponding clamping plates 12, such as by snap-fit. The driving component includes a screw 14, a limiting rod 16, and a second drive motor 15. The screw 14 is parallel to the limiting rod 16, and both ends of the screw 14 are rotatably mounted on one of the pairs of support columns 3. Both ends of the limiting rod 16 are fixedly connected to the pair of support columns 3. The two ends of the screw 14 are provided with threads in opposite directions. The upper parts of the pair of clamping plates 12 are respectively screwed onto the two threads of the screw 14. The limiting rod 16 is threaded onto the pair of clamping plates 12 to restrict the rotation of the clamping plates 12 (e.g., ...). Figure 4As shown), one end of the screw 14 rotates out of the support column 3, and the protruding end of the screw 14 is coaxially fixed to the output shaft of the second drive motor 15, which is mounted on the support column 3. The top of the clamping plate 12 is provided with a mounting plate 11, and a pair of moving tubes 8 correspond to a pair of mounting plates 11. Each moving tube 8 has a pair of connecting rods 10 on both sides, and the connecting rods 10 are fixed to the side wall of the moving tube 8. The connecting rods 10 are vertically arranged, and the horizontal line connecting the pair of connecting rods 10 is perpendicular to the central axis of the moving tube 8. The tops of both connecting rods 10 are fixed to the bottom of the mounting plate 11, so that when the drive motor starts, it drives the pair of clamping plates 12 to move closer to each other. The movement causes a pair of auxiliary blocks 13 to clamp the two folded edges of the color steel plate 7. In actual use, the bottom of the clamping plate 12 does not contact the transmission belt. When the auxiliary blocks 13 are removed from the clamping plate 12, the color steel plate 7 moves with the conveyor belt 1. The two inner walls of the first glue outlet channel 17 to the third glue outlet channel 25 are respectively the first inner wall and the second inner wall along their length direction. One end of the third bristle 26 is fixed to the first inner wall of its corresponding glue outlet channel, and one end of the first bristle 18 is fixed to the second inner wall of its corresponding glue outlet channel. This design can avoid the movement obstruction caused by the overlap of the bristles of the middle tube 9 and the moving tube 8 when the moving tube 8 is moved.

[0040] In the above technical solution, when using color steel plates 7 of different widths but the same thickness, and thus requiring adjustment of the glue dispensing box length, the color steel plate 7 is placed on the conveyor belt 1. Initially, the glue dispensing box is at its longest length. At this time, the second motor is started, driving a pair of clamping plates 12 to move relative to each other, clamping the color steel plate 7. During this process, the relative movement of the pair of clamping plates 12 drives a pair of moving tubes 8 to move synchronously, thereby shortening the length of the glue dispensing box. When the pair of clamping plates 12 (auxiliary blocks 13) clamp the color steel plate 7, the glue dispensing box is just located between a pair of side walls (folded edges) of the color steel plate 7, and the two ends of the glue dispensing box are close to each other. The side wall of the color steel plate 7 (the distance between the clamping plate 12 and the wall of the glue dispensing box needs to be designed in advance, which is achieved by reserving the auxiliary block 13, the position of the folded edge of the color steel plate 7, and the distance between the glue dispensing box and the side wall of the color steel plate 7). After the length of the glue dispensing box is adjusted to the appropriate level, the auxiliary block 13 is removed. At this time, the color steel plate 7 can move with the conveyor belt 1. After the glue dispensing is stable, the conveyor belt 1 can be started to perform the glue application operation. When applying color steel plates 7 of different widths and thicknesses, ensure that the distance between the clamping plate 12 and the wall of the glue dispensing box remains unchanged. By replacing the auxiliary block 13 of different thicknesses, it can be adapted to color steel plates 7 of different thicknesses.

[0041] The beneficial effect of adopting this technical solution is that, by designing the moving tube 8, intermediate tube 9, clamping plate 12, auxiliary block 13, mounting plate 11, connecting rod 10, and driving component, a structure with an adjustable glue dispensing box length to adapt to color steel plates 7 of different widths is provided, which is highly practical.

[0042] In another technical solution, brush bristles are provided on both inner walls of the adhesive dispensing channel where the mounting wall is located; specifically, second brush bristles 24 are provided on both the first and second inner walls of the second adhesive dispensing channel 23, one end of the second brush bristle 24 is fixed to the corresponding inner wall, and the other end of the second brush bristle 24 extends out of the second adhesive dispensing channel 23; the beneficial effect of this technical solution is that by designing second brush bristles 24 on both inner walls of the second adhesive dispensing channel 23, the adhesive can be better contacted with the second brush bristles 24.

[0043] In another technical solution, a pair of vertical support columns 3 are provided on both sides of the conveying assembly, and mounting blocks 4 are provided on the extended ends of the pair of support columns 3. The raw material tank 5 is installed on the top of the mounting block 4. Specifically, a mounting block 4 is fixed to the top of the pair of support columns 3, and the raw material tank 5 is installed on the mounting block 4. The raw material tank 5 is located directly above the dispensing box. The beneficial effect of this technical solution is that by designing the mounting block 4, a method for installing the raw material tank 5 is provided. By installing the raw material tank 5 directly above the dispensing box, the glue in the raw material tank 5 can be better guided into the dispensing box.

[0044] In another technical solution, the piston 501 is provided with a vertical piston rod 32, and the mounting block 4 is provided with a vertical mounting post 30; the pressure-applying component includes a drive motor, a gear 28, a support rod, a vertical rack 29, and a horizontal support plate 31. The upper part of the mounting post 30 is provided with the drive motor, and the output end of the drive motor is coaxially fixed to the gear 28 through the support rod. The gear 28 meshes with the rack 29, and the bottom of the rack 29 is detachably connected to the piston rod 32. The rack 29 is slidably mounted on the support plate 31, and the support plate 31 is fixedly connected to the mounting post 30. Specifically, the mounting block 4 is provided with a vertical mounting post 30, and the mounting post 30 is provided with a drive motor, which is a third drive motor 27. The output shaft of the third drive motor 27 is coaxially provided with a support rod, and the other end of the support rod is coaxially fixed to a vertical gear 28. The gear 28 meshes with a vertical rack 29. A horizontal support plate 31 is also provided on the upper part of the column 30. The rack 29 is slidably connected to the support plate 31. The slidable connection can be that the support plate 31 is provided with a pulley, and the rack 29 is provided with a sliding groove along its length that is adapted to the pulley. The rack 29 is slidably connected to the support plate 31 through the sliding groove and the pulley. The bottom of the rack 29 is detachably connected to the top of the piston rod 32. In this technical solution, when the third drive motor 27 is started, the output shaft of the third drive motor 27 rotates, driving the gear 28 to rotate. The rotation of the gear 28 drives the rack 29 to move up and down, thereby driving the piston 501 to move up and down. In actual use, a reduction motor can be designed or the rotation speed of the third motor can be controlled according to the situation. The beneficial effect of adopting this technical solution is that by designing and installing the column 30, the third drive motor 27, the gear 28, the support rod, the support plate 31, and the rack 29, a structure for a pressure-applying component is provided, which is widely available and easy to install and disassemble.

[0045] In another technical solution, each of the opposite sidewalls of the pair of clamping plates 12 is provided with a slot, and the auxiliary block 13 is provided with a locking block that matches the slot. The auxiliary block 13 is detachably connected to the clamping plate 12 through the locking block and the slot. The beneficial effect of this technical solution is that by designing the slot and the locking block, a locking method is provided, which makes the clamping plate 12 and the auxiliary block 13 detachably connected and easy to install.
