Description

Technical Field

[0001] This utility model relates to the field of adhesive bonding machine technology, specifically to a fabric positioning structure for an adhesive bonding machine. Background Technology

[0002] The main function of a seam sealing machine is to apply a waterproof tape to the seam edges of an object, thereby achieving a waterproof effect. The working principle of a seam sealing machine is to use high temperature to make the product tacky, and then achieve a waterproof effect after cooling. This type of machine is widely used for waterproofing seams in various waterproof clothing and outdoor sports products, such as raincoats, waterproof shoes and hats, tents, waterproof jackets, and waterproof diving suits.

[0003] Chinese Patent Publication No. CN215620110U discloses a fabric positioning structure for a waterproof seam sealing machine, relating to the field of fabric seam sealing positioning. It includes a bracket, a first positioning plate, and two second positioning plates. The first positioning plate is located below the two second positioning plates and is slidably disposed on the front side of the bracket. The two second positioning plates are fixed to each other by two fixing rods, and a positioning opening is provided between the two second positioning plates. The rear second positioning plate is fixedly connected to the bracket. An elastic adjustment mechanism is provided on the lower front side of the bracket, and the upper end of the upright rod in the elastic adjustment mechanism is fixedly connected to the lower middle part of the first positioning plate. This utility model facilitates the adjustment of the pressure value during the positioning of the seam sealing fabric, thereby easily meeting the positioning needs between different fabrics and facilitating user operation.

[0004] However, this device has the following drawback: when the fabric shifts along the feed rollers and the operator fails to notice in time, the adhesive tape cannot be accurately pressed onto the seam of the fabric, resulting in misalignment of the tape. To address this drawback, we propose a fabric positioning structure for the tape-sealing machine. Utility Model Content

[0005] The purpose of this invention is to provide a fabric positioning structure for a glue-sealing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fabric positioning structure for a pressure bonding machine, comprising:

[0007] The frame includes an operating table, a support arm fixedly mounted on the upper surface of the operating table, and a pressing structure disposed on the right side of the support arm. The pressing structure consists of an upper pressing roller and a drive assembly that can drive the upper pressing roller to move.

[0008] The drive assembly includes a first cylinder fixedly mounted on the right end of the support arm, and a roller seat fixedly mounted on the telescopic end of the first cylinder, with the upper pressure roller rotatably mounted on the inner wall of the roller seat.

[0009] The fabric positioning structure includes two connecting frames fixedly installed on the front of the roller seat, guide rods fixedly installed on the inner walls of the two connecting frames, guide blocks slidably installed on the surfaces of the two guide rods, support rods fixedly installed on the back sides of the two guide blocks, and positioning wheels rotatably installed on the opposite sides of the two support rods. An emergency stop assembly is provided inside the connecting frames.

[0010] The emergency stop assembly includes a moving contact fixedly mounted on the lower surface of the guide block, and a fixed contact fixedly mounted on the bottom wall of the connecting frame;

[0011] A fabric placement structure, comprising a fabric placement plate fixedly installed on the upper surface of an operating table, a groove formed on the upper surface of the fabric placement plate, and a lower pressure roller rotatably installed on the inner wall of the groove.

[0012] A cleaning structure is provided on the upper surface of the operating table for cleaning the lower pressure roller.

[0013] Preferably, a motor that can drive the upper pressure roller to rotate is fixedly installed on the left side of the roller seat.

[0014] Preferably, a first compression spring is sleeved on the surface of the guide rod, one end of the first compression spring is fixedly connected to the inner top wall of the connecting frame, and the other end of the first compression spring is fixedly connected to the upper surface of the guide block.

[0015] Preferably, a support plate is fixedly installed on the upper surface of the roller seat, and the surface of the support plate is respectively provided with a belt pulley, a tension pulley, and an air nozzle.

[0016] Preferably, the cleaning structure includes a second cylinder fixedly mounted on the upper surface of the operating table, a mounting plate fixedly mounted on the telescopic end of the second cylinder, a sliding hole formed on the upper surface of the mounting plate, a sliding rod slidably mounted on the inner wall of the sliding hole, a blade mounting seat fixedly mounted on the upper end of the sliding rod, and a scraper disposed on the inner wall of the blade mounting seat.

[0017] Preferably, the surface of the blade mounting base is threaded with a locking bolt that can lock the scraper.

[0018] Preferably, a second compression spring is sleeved on the surface of the sliding rod, one end of the second compression spring is fixedly connected to the lower surface of the blade mounting seat, the other end of the second compression spring is fixedly connected to the upper surface of the mounting plate, and a baffle is fixedly installed at the lower end of the sliding rod.

[0019] This sealing machine uses a fabric positioning structure. When the fabric is placed on the fabric placement plate, the seam area is positioned on the lower pressure roller. Then, a drive assembly drives the upper pressure roller to contact the seam area. At this point, the positioning roller presses against the seam area, which is the sealing point. Because the seam area is higher than the fabric, the positioning roller is slightly raised, causing the moving contact to disengage from the fixed contact. The drive motor then rotates the upper pressure roller, moving the fabric for sealing. When the seam area shifts away from the positioning roller, it disengages, causing the positioning roller to descend. A first compression spring then drives the moving contact to contact the fixed contact. Once the moving contact contacts the fixed contact, the motor stops rotating, stopping the sealing and fabric feeding when the sealing position shifts, thus preventing sealing misalignment.

[0020] This adhesive pressing machine uses a cloth positioning structure and a cleaning mechanism. When the lower pressure roller is pressing adhesive and causes adhesive to adhere to it, the second cylinder is driven, which in turn drives the scraper to contact the lower pressure roller. The second compression spring generates a buffering force to prevent the scraper from being overloaded and damaging the lower pressure roller. Afterward, rotating the lower pressure roller allows the scraper to quickly remove the adhesive from it, thus facilitating the cleaning of the adhesive on the lower pressure roller.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a fabric positioning structure for a glue pressing machine, comprising: a frame, a fabric positioning structure, a fabric placement structure, and a cleaning structure.

[0029] The frame includes an operating table 1, a support arm 2 fixedly installed on the upper surface of the operating table 1, and a pressing structure provided on the right side of the support arm 2. The pressing structure consists of an upper pressing roller 3 and a drive assembly that can drive the upper pressing roller 3 to move.

[0030] The drive assembly includes a first cylinder 5 fixedly mounted on the right end of the support arm 2, and a roller seat 6 fixedly mounted on the telescopic end of the first cylinder 5. The upper pressure roller 3 is rotatably mounted on the inner wall of the roller seat 6. A motor 16 that can drive the upper pressure roller 3 to rotate is fixedly mounted on the left side of the roller seat 6. A support plate 4 is fixedly mounted on the upper surface of the roller seat 6. A belt pulley 18, a tensioning pulley 19, and a nozzle 20 are respectively provided on the surface of the support plate 4. Driving the first cylinder 5 can drive the roller seat 6 to move, thereby driving the upper pressure roller 3, belt pulley 18, tensioning pulley 19, and nozzle 20 to move synchronously. The belt pulley 18, tensioning pulley 19, and nozzle 20 are all existing technologies, so they will not be described in detail.

[0031] The fabric placement structure includes a fabric placement plate 14 fixedly installed on the upper surface of the operating table 1, a groove formed on the upper surface of the fabric placement plate 14, and a lower pressure roller 15 rotatably installed on the inner wall of the groove.

[0032] Place the fabric on the fabric placement plate 14, and then place the sewing position of the fabric on the lower pressure roller 15. Then, drive the first cylinder 5 to drive the upper pressure roller 3 to contact the sewing position of the fabric. At this time, the sewing position of the fabric is between the upper pressure roller 3 and the lower pressure roller 15. Then, drive the motor 16 to drive the upper pressure roller 3 to rotate, so that the upper pressure roller 3 can be used to drive the fabric to move. When the tape on the upper pressure roller 3 contacts the fabric, the tape can be pressed onto the fabric.

[0033] The fabric positioning structure includes two connecting frames 7 fixedly installed on the front of the roller seat 6, guide rods 8 fixedly installed on the inner walls of the two connecting frames 7, guide blocks 9 slidably installed on the surfaces of the two guide rods 8, support rods 10 fixedly installed on the back of the two guide blocks 9, and positioning wheels 11 rotatably installed on the opposite sides of the two support rods 10. The width of the positioning wheels 11 is adapted to the width of the fabric seam.

[0034] An emergency stop assembly is provided inside the connecting frame 7. The emergency stop assembly includes a moving contact 12 fixedly installed on the lower surface of the guide block 9 and a fixed contact 13 fixedly installed on the inner bottom wall of the connecting frame 7. A first compression spring 17 is sleeved on the surface of the guide rod 8. One end of the first compression spring 17 is fixedly connected to the inner top wall of the connecting frame 7, and the other end of the first compression spring 17 is fixedly connected to the upper surface of the guide block 9. The fixed contact 13, the moving contact 12, and the motor 16 are all connected to an external control system. In the initial state, the first compression spring 17 can drive the moving contact 12 to contact the fixed contact 13. When the fixed contact 13 contacts the moving contact 12, the motor 16 will be de-energized.

[0035] When the drive assembly drives the upper pressure roller 3 to contact the fabric seam position, the positioning wheel 11 will press on the fabric seam position. The fabric seam is the glue pressing position. Since the fabric seam position is higher than the fabric, the positioning wheel 11 will be driven to lift slightly, thereby driving the moving contact 12 to disengage from the fixed contact 13. Then the drive motor 16 can drive the upper pressure roller 3 to rotate, thereby driving the fabric to move for glue pressing. When the fabric seam is offset from the positioning wheel 11, the seam position will disengage from the positioning wheel 11, thereby causing the positioning wheel 11 to drop. The first compression spring 17 will drive the moving contact 12 to contact the fixed contact 13. When the moving contact 12 contacts the fixed contact 13, the motor 16 will stop rotating, thereby stopping the glue pressing and fabric conveying after the fabric glue pressing position is offset, thus avoiding the problem of glue pressing offset.

[0036] A cleaning structure is installed on the upper surface of the operating table 1 for cleaning the lower pressure roller 15. The cleaning structure includes a second cylinder 21 fixedly installed on the upper surface of the operating table 1, a mounting plate 22 fixedly installed on the telescopic end of the second cylinder 21, a sliding hole opened on the upper surface of the mounting plate 22, a sliding rod 23 slidably installed on the inner wall of the sliding hole, a blade mounting seat 24 fixedly installed on the upper end of the sliding rod 23, and a scraper 25 provided on the inner wall of the blade mounting seat 24. The surface of the blade mounting seat 24 is threaded with a locking bolt 26 that can lock the scraper 25.

[0037] After placing the scraper 25 into the blade mounting base 24, tighten the locking bolt 26 to fix the scraper 25 onto the blade mounting base 24. Loosening the locking bolt 26 allows the scraper 25 to be removed from the blade mounting base 24 for replacement.

[0038] A second compression spring 27 is sleeved on the surface of the sliding rod 23. One end of the second compression spring 27 is fixedly connected to the lower surface of the blade mounting seat 24, and the other end of the second compression spring 27 is fixedly connected to the upper surface of the mounting plate 22. A baffle 28 is fixedly installed at the lower end of the sliding rod 23, which can prevent the sliding rod 23 from detaching from the mounting plate 22.

[0039] When the adhesive adheres to the lower pressure roller 15, the second cylinder 21 is driven, which drives the scraper 25 to contact the lower pressure roller 15. The second compression spring 27 generates a buffering force to prevent the scraper 25 from being over-stressed and damaging the lower pressure roller 15. After that, rotating the lower pressure roller 15 allows the scraper 25 to quickly scrape off the adhesive on the lower pressure roller 15, thus facilitating the cleaning of the adhesive on the lower pressure roller 15.

[0040] Working principle: 1. First, place the fabric on the fabric placement plate 14, and then place the sewing position of the fabric on the lower pressure roller 15;

[0041] The upper pressure roller 3 is driven to contact the sewing position of the fabric using the drive assembly. At this time, the sewing position of the fabric is between the upper pressure roller 3 and the lower pressure roller 15. Since the sewing position of the fabric is higher than the fabric, the positioning wheel 11 will be driven to lift slightly, thereby driving the moving contact 12 to disengage from the fixed contact 13.

[0042] The drive motor 16 can drive the upper pressure roller 3 to rotate, thereby driving the fabric to move for pressing;

[0043] When the seam of the fabric deviates from the positioning wheel 11, the seam position will disengage from the positioning wheel 11, thereby causing the positioning wheel 11 to descend. The first compression spring 17 will drive the moving contact 12 to contact the fixed contact 13. After the moving contact 12 contacts the fixed contact 13, the motor 16 will stop rotating, thereby stopping the pressing and conveying of the fabric after the pressing position of the fabric deviates.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
