DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] The embodiment of the present application discloses a cloth guide heating device, which is installed on a heat sealing machine. The cloth guide heating device includes a cloth guide seat 1, a rotating seat 2 and a fixed seat 3. The cloth guide seat 1 can be made of bakelite material. The cloth guide seat 1 is vertically spaced apart and provided with a first cloth guide groove 11 and a second cloth guide groove 12, wherein the first cloth guide groove 11 is located below the second cloth guide groove 12. The cloth guide seat 1 is also provided with a material guide groove 13 between the first cloth guide groove 11 and the second cloth guide groove 12.

[0034] Specifically, the first fabric guide groove 11 has a first opening on one side along its width direction, and the second fabric guide groove 12 has a second opening on one side along its width direction. The first fabric guide groove 11 and the second fabric guide groove 12 are vertically staggered, and the first opening is opposite to the second opening. The first fabric guide groove 11 is used for inserting a layer of fabric, and the layer of fabric can be pushed along the length direction of the first fabric guide groove 11; the second fabric guide groove 12 is used for inserting another layer of fabric, and the layer can be pushed along the length direction of the second fabric guide groove 12. The two layers of fabric have overlapping parts in the vertical projection. The material guide groove 13 is used for the tape 9 to pass through, so that the tape 9 can be bonded between the overlapping parts of the two layers of fabric later.

[0035] The cloth guide seat 1 is provided with two brass hot air pipes 4 at the outlet of the material guide trough 13, and the outside of the hot air pipes 4 is wrapped with asbestos to avoid scalding the operator. The two hot air pipes 4 are arranged vertically at intervals so that the adhesive tape 9 can pass between the two hot air pipes 4. The length direction of the hot air pipe 4 is the same as the width direction of the material guide trough 13, and the blowing ports 41 of the two hot air pipes 4 are opened along the length direction of the hot air pipe 4. Both blowing ports 41 face the adhesive tape 9, and both blowing ports 41 are inclined toward the side away from the cloth guide seat 1. One end of the hot air pipe 4 is threadedly connected to the cloth guide seat 1 to adjust the air outlet angle of the blowing port 41 of the hot air pipe 4. In the present embodiment, the angle between the blowing port 41 and the adhesive tape 9 is about 30°.

[0036] In this embodiment, the cloth guide seat 1 is provided with a connecting hole 16 on the same side of the two hot air pipes 4. The two hot air pipes 4 are connected to the connecting hole 16. The connecting hole 16 is connected to a hose, which is connected to the main air supply pipe 42 for providing hot air on other components. The hose is made of a high-temperature resistant Teflon tube. After the upper and lower sides of the tape 9 pass through the hot air blown by the hot air pipe 4, the cloth and the tape 9 are bonded and connected through other subsequent devices. The setting of the hose ensures that the cloth guide seat 1 is not affected when it rotates.

[0037] The first reversing member and the second reversing member are installed on the fabric guide seat 1. The first reversing member is used to turn and guide the adhesive tape 9 into the material guide trough 13; the second reversing member is used to change the direction of the adhesive tape 9 to the same direction as the outlet of the material guide trough 13, that is, the direction of the adhesive tape 9 after being changed by the second reversing member is the same as the length direction of the material guide trough 13.

[0038] Specifically, the cloth guide seat 1 has a first reversing opening 131 on one side of the guide groove 13 in the width direction, and the direction of the first reversing opening 131 is the same as the first opening direction. The cloth guide seat 1 has a second reversing opening 132 on one end of the guide groove 13 away from the outlet.

[0039] The first reversing member includes a first reversing roller 5. Both ends of the first reversing roller 5 are rotatably mounted at the first reversing port 131 through bearings. The axial direction of the first reversing roller 5 is horizontally arranged and parallel to the length direction of the guide groove 13, so that the adhesive tape 9 passes around the first reversing roller 5 and enters the guide groove 13 from the first reversing port 131.

[0040] The second reversing member includes a second reversing roller 6. Both ends of the second reversing roller 6 are rotatably mounted at the second reversing port 132 through bearings. In this embodiment, the angle formed by the axes of the first reversing roller 5 and the second reversing roller 6 in the vertical projection is about 45°. After the first reversing roller 5 turns, the adhesive tape 9 passes through the guide groove 13 toward the second reversing port 132, then winds around the second reversing roller 6, and passes through the guide groove 13 again from the second reversing port 132, and changes direction to the same direction as the outlet of the guide groove 13, so that the adhesive tape 9 can smoothly pass through the outlet of the guide groove 13. And through the arrangement of the first reversing roller 5 and the second reversing roller 6, the cloth moving along the first cloth guide groove 11 and the second cloth guide groove 12 does not interfere with the adhesive tape, and maintains normal operation.

[0041] Furthermore, a partition 14 is installed in the guide trough 13, one side of the partition 14 extends to the first reversing port 131, and the other side extends to the second reversing port 132. The partition 14 divides the guide trough 13 into two layers, upper and lower. The upper part of the partition 14 is used for the adhesive tape 9 to move toward the second reversing roller 6 after passing through the first reversing roller 5, and the lower part of the partition 14 is used for the adhesive tape 9 to move toward the outlet of the guide trough 13 after passing through the second reversing roller 6. Since the adhesive tape 9 is soft, when the adhesive tape 9 first passes into the guide trough 13, the setting of the partition 14 can easily insert the adhesive tape 9 from the first reversing port 131, and easily pass through the second reversing port 132 under the separation of the partition 14, and then bypass the second reversing roller 6 to change direction, insert from the lower part of the partition 14, and pass through the outlet of the guide trough 13.

[0042] The cloth guide seat 1 is provided with an elastic sheet 15 in the guide groove 13, and the elastic sheet 15 is inclined from top to bottom toward the outlet of the guide groove 13. The elastic sheet 15 is used to abut the adhesive tape 9 against the side wall at the bottom of the guide groove 13, so that the adhesive tape 9 can remain flat and will not easily move along the width direction of the guide groove 13. The lower end of the elastic sheet 15 abuts against the position of the guide groove 13 near the outlet. The elastic sheet 15 is detachably mounted on the cloth guide seat 1. The cloth guide seat 1 is provided with a mounting groove at the upper end of the inner wall of the guide groove 13, and the upper end of the elastic sheet 15 is integrally connected with a plug-in shaft 151, the plug-in shaft 151 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 151 is larger than the diameter of the installation groove, so that after the plug-in shaft 151 is inserted into the installation groove, the side wall of the plug-in shaft 151 abuts against the installation groove, remains stable, and will not easily move along the axial direction of the installation groove.

[0043] Furthermore, in order to be able to bond the tape 9 to the bends or curved edges of the cloth, the cloth guide seat 1 is fixedly mounted on the rotating seat 2, and the fixed seat 3 is fixedly mounted on the bottom of the workbench 8. In order to facilitate the movement of the cloth, the workbench 8 is provided with a rotating hole so that the rotating seat 2 is located in the rotating hole, and the upper end surface of the rotating seat 2 is flush with the upper end surface of the workbench 8. In this embodiment, the bottom groove wall of the first cloth guide groove 11 is the upper end surface of the rotating seat 2.

[0044] An adjustment assembly 7 for controlling the rotation angle of the rotating seat 2 is installed at the bottom of the fixed seat 3. The adjustment assembly 7 includes an adjustment rod 71 and a driving member. The rotating seat 2 is a fan-shaped structure, and one side of the tip of the rotating seat 2 is hinged to the fixed seat 3, so that the rotating seat 2 can rotate in a horizontal plane around the hinge. An adjustment hole 31 is provided on the fixed seat 3, and the adjustment hole 31 is an arc structure with the hinge point of the rotating seat 2 as the center of the circle. The adjustment rod 71 is vertically connected to the bottom of the rotating seat 2 and extends to the outside of the fixed seat 3 through the adjustment hole 31.

[0045] The driving member includes a screw rod 72 and a moving block 73. The screw rod 72 is rotatably mounted at the bottom of the fixed seat 3, and the axial direction of the screw rod 72 is parallel to the axial direction of the hot air pipe 4. The moving block 73 is sleeved on the screw rod 72 and threadedly connected thereto. The moving block 73 is provided with a clamping groove 731 along the length direction of the material guide groove 13, so that the clamping groove 731 is clamped on both sides of the adjusting rod 71. The upper end of the moving block 73 abuts against the side wall at the bottom of the fixed seat 3, so that when the screw rod 72 rotates, the moving block 73 moves along the axial direction of the screw rod 72, and the adjusting rod 71 moves with the moving block 73, thereby driving the rotating seat 2 to rotate. Push wheels are installed at both ends of the screw rod 72, and the workbench 8 is provided with a through hole, and the push wheel is exposed at the through hole, so that the staff can push the push wheel from the upper end surface of the workbench 8, so that the rotating seat 2 drives the cloth guide seat 1 to rotate, so as to facilitate the subsequent bonding work at the turning point of the cloth, and the operation is simple. In other embodiments, a motor may be used to drive the screw rod 72 to rotate, and a button may be used to control the forward or reverse rotation of the motor.

[0046] The present application also discloses a bonding device, comprising the above-mentioned cloth guide heating device and a machine body, wherein the cloth guide heating device is installed on a workbench 8 of the machine body.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
