Description

Technical Field

[0001] The present application relates to a bonding device and a method of using the same. Background Art

[0002] At present, among bonding equipment, seam sealing machines in particular are widely used in the splicing of fabrics such as tents, raincoats, and waterproof clothing. The hot-melt tape is heated by blowing air through a hot air duct so that the fabric and the hot-melt tape are bonded and connected after being rolled by a rubber wheel to achieve a sealing effect. However, at the junction of the edge of the fabric and the tape, the overlapping position of the edge of the fabric and the tape is prone to offset during operation, resulting in a decrease in the bonding quality of the product. In addition, most manufacturers currently use multiple bonding processes for double-layer fabrics due to equipment limitations. After one layer of fabric is bonded to one side of the tape, the other layer of fabric is bonded to the other side of the tape. The entire bonding process is cumbersome, greatly reducing work efficiency. Summary of the invention

[0032] 4. The arrangement of the tape reel, the driving wheel group and the tensioning wheel group pulls the tape toward the cloth guide heating device; since the tape reel actively delivers the tape, it can effectively prevent the tape from being broken due to excessive tension; when the tape needs to be retracted for a certain length, the motor drives the driving wheel to reverse, so that the tape retracts. At this time, the lifting wheel keeps the tape tensioned and wound around the tensioning wheel under the action of its own gravity, so as to prevent the tape from being separated from the tensioning wheel when retracting;

[0033] 5. By adjusting the setting of the component, the rotating seat can be controlled to drive the cloth guide seat to rotate a certain angle, so as to guide the arc edge of the cloth, so that the rolling device can smoothly bond it. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] The following is combined with Figure 1-16 This application is described in further detail.

[0052] The embodiment of the present application discloses a bonding device, including a machine body 1, a cloth guide heating device, a rolling device, a plate pressing device, a hot air device, and an active tape conveying device. In the vertical projection plane, the cloth guide heating device, the rolling device, and the plate pressing device are arranged in sequence from the side of the machine body 1 close to the staff to the side away from the staff. The cloth guide heating device is installed on the workbench of the machine body 1, and the rolling device and the plate pressing device are installed at the end of the cantilever beam of the machine body 1. The hot air device is used to blow air to heat the roller, the cloth, and the tape 2. The active tape conveying device is used to convey the tape 2. An integrated controller 3 is also installed on the machine body 1 for controlling the operation of each device.

[0053] Active belt conveyor:

[0054] The machine comprises a tape reel 4, a tensioning wheel set and a driving wheel set 7. The tape reel 4 is installed on the side of the machine body 1 away from the rolling device. The tape reel 4 is driven by a motor, and the tensioning wheel set is distributed along the length direction of the cantilever beam of the machine body 1 and is staggered up and down, so that the tape 2 is arranged on the tensioning wheel set in an S shape.

[0055] The driving wheel group 7 is located below the end of the tensioning wheel group away from the tape reel 4. The driving wheel group includes a driving wheel 7 and an adjusting wheel 8. The driving wheel 7 is driven by a motor with forward and reverse rotation functions. The adjusting wheel 8 adjusts the distance between itself and the driving wheel 7 by adjusting bolts so that the tape 2 passes between the driving wheel 7 and the adjusting wheel 8.

[0056] The tensioning wheel group includes a plurality of tensioning wheels 5 and a lifting wheel 6. A lifting rail is installed on the cantilever beam, and the lifting wheel 6 slides on the lifting rail through a slider. A limit rod is provided at the lower end of the lifting rail to limit the lifting wheel 6 from being separated from the lower end of the lifting rail. The adhesive tape 2 passes around the lower end of the lifting wheel 6; when the driving wheel 7 reverses and drives the adhesive tape 2 to retreat, the lifting wheel 6 presses the adhesive tape 2 under its own gravity to keep the adhesive tape 2 in a tensioned state.

[0057] The rolling device includes a lower rubber wheel 30, an upper rubber wheel 29 and a first lifting assembly 31 for driving the upper rubber wheel 29 to rise or fall. The rolling device is used to roll and bond the cloth and the tape 2.

[0058] The tape 2 wound on the tape reel 4 is pulled out and placed on the tension wheel group, then inserted between the driving wheel 7 and the adjusting wheel 8, and then enters the cloth guide heating device, and is bonded under the rolling traction of the rolling device. When conveying the tape 2, the tape reel 4 is actively rotated under the drive of the motor to actively send out the tape 2. At the same time, the upper rubber wheel 29, the driving wheel 7 and the tape reel 4 rotate synchronously to pull and guide the tape 2, and keep the speed of the tape 2 at the upper rubber wheel 29, the driving wheel 7 and the tape reel 4 at the same speed. By actively sending out the tape 2 through the tape reel 4, it can effectively prevent the tape 2 from being broken due to excessive force.

[0059] Fabric guide heating device:

[0060] The cloth guide seat 9 comprises a cloth guide seat 9, a rotating seat 10 and a fixed seat 11. The cloth guide seat 9 can be made of bakelite. The cloth guide seat 9 is sequentially provided with a first cloth guide groove 12, a material guide groove 14 and a second cloth guide groove 13 from bottom to top.

[0061] The first fabric guide groove 12 has a first opening on one side along its width direction, and the second fabric guide groove 13 has a second opening on one side along its width direction. The first opening is opposite to the second opening so that the fabric inserted from the first opening and the fabric inserted from the second opening partially overlap in the vertical projection. The first fabric guide groove 12 is used for inserting the first layer of fabric and enabling the fabric to be pushed along the length direction of the first fabric guide groove 12. The second fabric guide groove 13 is used for inserting the second layer of fabric and enabling the fabric to be pushed along the length direction of the second fabric guide groove 13. The two layers of fabric have overlapping parts in the vertical projection. The material guide groove 14 is used for allowing the adhesive tape 2 to pass through so that the adhesive tape 2 can be subsequently bonded between the overlapping parts of the two layers of fabric.

[0062] The cloth guide seat 9 is provided with two brass blow pipes 15 at the outlet of the material guide trough 14, and the outside of the blow pipes 15 is wrapped with asbestos to avoid scalding the operator. The two blow pipes 15 are arranged at intervals in the vertical direction so that the adhesive tape 2 can pass between the two blow pipes 15. The length direction of the blow pipe 15 is the same as the width direction of the material guide trough 14, and the blowing ports of the two blow pipes 15 are opened along the length direction of the blow pipe 15. Both blowing ports are facing the adhesive tape 2, and both blowing ports are inclined toward the side away from the cloth guide seat 9. One end of the blow pipe 15 is threadedly connected to the cloth guide seat 9 to adjust the air outlet angle of the blowing port of the blow pipe 15. In the present embodiment, the angle between the blowing port and the adhesive tape 2 is about 30°.

[0063] In this embodiment, the cloth guide seat 9 is provided with a connecting hole 16 on the same side of the two blowing pipes 15. The two blowing pipes 15 are connected to the connecting hole 16. The connecting hole 16 is connected to a hose, and the hose is connected to the hot air device. The hose is a high-temperature resistant Teflon tube. After the upper and lower sides of the tape 2 pass through the hot air blown by the blowing pipe 15, the cloth and the tape 2 are bonded and connected through other subsequent devices. The setting of the hose ensures that the cloth guide seat 9 is not affected when it rotates.

[0064] The cloth guide seat 9 is provided with a first reversing roller 19 and a second reversing roller 20. The cloth guide seat 9 is provided with a first reversing opening 17 on one side of the guide groove 14 in the width direction. The first reversing opening 17 is in the same direction as the first opening. The first reversing roller 19 is rotatably provided at the first reversing opening 17 so that the adhesive tape 2 enters the guide groove 14 around the first reversing roller 19. The cloth guide seat 9 is provided with a second reversing opening 18 at one end of the guide groove 14 away from the outlet. The second reversing roller 20 is rotatably provided at the second reversing opening 18 so that the adhesive tape 2 enters the guide groove 14 from the first reversing opening 17, passes through the guide groove 14 toward the second reversing opening 18 after bypassing the first reversing roller 19, and then passes through the guide groove 14 around the second reversing roller 20 and turns to enter the guide groove 14 in the same direction as the outlet of the guide groove 14. The first reversing roller 19 and the second reversing roller 20 are in the vertical projection plane, and the angle between the two is about 45°, and both are rotatably mounted on the cloth guide seat 9 through bearings. By disposing the first reversing roller 19 and the second reversing roller 20, the cloth moving along the first cloth guiding groove 12 and the second cloth guiding groove 13 does not interfere with the adhesive tape 2, and maintains normal operation.

[0065] Furthermore, a partition 21 is installed in the guide trough 14, one side of the partition 21 extends to the first reversing port 17, and the other side extends to the second reversing port 18. The partition 21 divides the guide trough 14 into two layers, upper and lower. The upper part of the partition 21 is used for the adhesive tape 2 to move toward the second reversing roller 20 after passing through the first reversing roller 19, and the lower part of the partition 21 is used for the adhesive tape 2 to move toward the outlet of the guide trough 14 after passing through the second reversing roller 20. Since the adhesive tape 2 is soft, when the adhesive tape 2 first passes into the guide trough 14, the setting of the partition 21 can easily insert the adhesive tape 2 from the first reversing port 17, and easily pass through the second reversing port 18 under the separation of the partition 21, and then bypass the second reversing roller 20 to change direction, insert from the lower part of the partition 21, and pass through the outlet of the guide trough 14.

[0066] The cloth guide seat 9 is provided with an elastic sheet 22 in the guide groove 14, and the elastic sheet 22 is inclined from top to bottom toward the outlet of the guide groove 1413. The elastic sheet 22 is used to abut the adhesive tape 2 against the side wall at the bottom of the guide groove 14, so that the adhesive tape 2 can remain flat and will not easily move along the width direction of the guide groove 14. The lower end of the elastic sheet 22 abuts against the position of the guide groove 14 near the outlet. The elastic sheet 22 is detachably mounted on the cloth guide seat 9. The cloth guide seat 9 is provided with a mounting groove at the upper end of the inner wall of the guide groove 14, and the upper end of the elastic sheet 22 is integrally connected with a plug-in shaft 23, the plug-in shaft 23 is hollow inside, and the side wall is grooved along its length direction to make it have elastic deformation ability. In the absence of external force, the outer diameter of the plug-in shaft 23 is larger than the diameter of the installation groove, so that after the plug-in shaft 23 is inserted into the installation groove, the side wall of the plug-in shaft 23 abuts against the installation groove, remains stable, and will not easily move along the axial direction of the installation groove.

[0067] Furthermore, in order to be able to bond the tape 2 to the bends or curved edges of the cloth, the cloth guide seat 9 is fixedly mounted on the rotating seat 10, the rotating seat 10 is rotatably mounted on the fixed seat 11, and the fixed seat 11 is fixedly mounted on the bottom of the workbench. In order to facilitate the movement of the cloth, the workbench is provided with a rotating hole so that the rotating seat 10 is located in the rotating hole, and the upper end surface of the rotating seat 10 is flush with the upper end surface of the workbench. In this embodiment, the bottom groove wall of the first cloth guide groove 12 is the upper end surface of the rotating seat 10.

[0068] An adjustment component for controlling the rotation angle of the rotating seat 10 is installed at the bottom of the fixed seat 11. The adjustment component includes an adjustment rod 24, a screw rod 25 and an adjustment block 26. The rotating seat 10 is a fan-shaped structure, and one side of the tip of the rotating seat 10 is hinged to the fixed seat 11, so that the rotating seat 10 can rotate in a horizontal plane around the hinge. An arc groove 27 is provided on the fixed seat 11, and the arc groove 27 takes the hinge point of the rotating seat 10 as the center. The adjustment rod 24 is vertically connected to the bottom of the rotating seat 10 and extends to the outside of the fixed seat 11 through the adjustment hole.

[0069] The screw rod 25 is rotatably mounted at the bottom of the fixed seat 11, and the axial direction of the screw rod 25 is parallel to the axial direction of the blowing pipe 15. The adjusting block 26 is sleeved on the screw rod 25 and is threadedly connected thereto. The adjusting block 26 is provided with a clamping groove 28 along the length direction of the material guide groove 14, so that the clamping groove 28 is clamped on both sides of the adjusting rod 24. The upper end of the adjusting block 26 abuts against the side wall at the bottom of the fixed seat 11, so that when the screw rod 25 rotates, the adjusting block 26 moves along the axial direction of the screw rod 25, and the adjusting rod 24 moves with the adjusting block 26, thereby driving the rotating seat 10 to rotate. Push wheels are installed at both ends of the screw rod 25, and a through hole is provided on the workbench, and the push wheel is exposed at the through hole, so that the staff can push the push wheel from the upper surface of the workbench, so that the rotating seat 10 drives the cloth guide seat 9 to rotate, so as to facilitate the subsequent bonding work at the bend of the cloth, and the operation is simple. In other embodiments, a motor may be used to drive the screw rod 25 to rotate, and a button may be used to control the forward or reverse rotation of the motor, thereby controlling the rotation angle of the rotating base 10 .

[0070] Rolling device:

[0071] It includes a lower rubber wheel 30, an upper rubber wheel 29, and a first lifting assembly 31 for driving the upper rubber wheel 29 to rise or fall. The lower rubber wheel 30 is installed at the bottom of the fixed seat 11. The fixed seat 11 and the workbench are both provided with clearance holes. The upper end of the lower rubber wheel 30 passes through the fixed seat 11 and the workbench, and its upper end is exposed above the workbench surface. The first lifting assembly 31 uses a cylinder to drive the upper rubber wheel 29 to descend, so as to achieve the purpose of bonding the cloth and the tape 2; the cylinder is installed at the end of the cantilever beam, and the piston rod of the cylinder is connected to the upper rubber wheel 29 through a connecting arm.

[0072] The upper rubber wheel 29 and the lower rubber wheel 30 are driven by the motor to rotate synchronously in opposite directions, so that the cloth and the adhesive tape 2 clamped between the upper rubber wheel 29 and the lower rubber wheel 30 can be bonded, and the cloth and the adhesive tape 2 can be pushed out horizontally along the workbench plane in a direction away from the staff. During the working process, the linear speed of the upper rubber wheel 29 and the driving wheel 7 is consistent. Compared with the traditional climbing type rolling device, for cloth with a larger area, horizontally pushing the cloth is more convenient.

[0073] Plate pressing device:

[0074] It includes a lower pressing plate 33, an upper pressing plate 32, and a second lifting assembly 34 that drives the upper pressing plate 32 to rise or fall.
