Description

Technical Field

[0001] The utility model relates to the technical field of traction mechanisms, in particular to a glass cloth traction mechanism for a gluing machine. Background Art

[0002] During the gluing process of the glass cloth passing through the gluing machine, in order to ensure continuous operation, when the previous roll of glass cloth is about to be unwound, the head of the other roll of glass cloth needs to be pulled to the splicing table (230℃ high-temperature hot plate table) and spliced with the tail of the previous roll of glass cloth. In order to achieve a better splicing effect, the surface of the pulled glass cloth needs to be kept flat and the tension is uniform. This is mainly determined by the glass cloth pulling mechanism. The glass cloth pulling mechanism usually includes a glass cloth clamping component and a transmission component. At present, the common glass cloth clamping component is mainly composed of a metal sheet and a metal groove clamping. During operation, the staff first manually pulls the cloth flat and fits it on the metal groove, and then presses it with a metal sheet to fix it. Finally, the transmission component drives the clamping component to move, thereby pulling the glass cloth to the splicing table.

[0003] However, there are the following deficiencies in this device:

[0004] The existing traction mechanism mainly relies on manual single-point pulling to flatten the cloth, which has low efficiency and easily causes uneven tension on the left and right sides of the cloth, resulting in breakage and scrapping of the glass cloth at the joint when passing through the extrusion wheel of the gluing machine;

[0005] The existing traction mechanism cannot adjust the tension of the cloth. During the traction process, the tension of the cloth is relatively loose, which causes wrinkles on the long section of glass cloth at the joint, resulting in a large amount of scrap.

[0006] In the existing traction mechanism, the clamping assembly is mainly composed of a metal sheet and a metal groove. During use, the metal sheet and the metal groove contact and rub against each other. After long-term use, metal foreign matter is easily generated, thereby affecting the product quality of the glass cloth after gluing. Utility Model Content

[0007] The purpose of the utility model is to provide a glass cloth traction mechanism for a gluing machine to solve the existing problems raised in the above background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a glass cloth traction mechanism of a gluing machine, comprising a traction rod, the traction rod comprising an extension section and a clamping section, the extension section being located on both sides of the clamping section, the clamping section comprising a semi-cylinder A and a semi-cylinder B, the two sides of the semi-cylinder A being connected to the extension section, connecting columns being provided on both sides of the top of the semi-cylinder A, the semi-cylinder B being sleeved on the connecting columns on both sides, the two sides of the top of the semi-cylinder B being rotatably connected with a buckle, a motor B being provided on one side of the traction rod, a bearing being provided on the inner side of the extension section, and the output end of the motor B being connected to the bearing.

[0009] Preferably, guide holes that are slidably engaged with the connecting columns are provided on both sides of the bottom of the semi-cylindrical body B, so that the semi-cylindrical body B can slide along the guidance of the connecting columns.

[0010] Preferably, the semi-cylindrical body A and the semi-cylindrical body B have the same thickness, both being 2 - 3 cm.

[0011] Preferably, the length of the connecting column is 1.0 - 2.5 cm, which controls the adjustable range of the gap between the semi-cylindrical body A and the semi-cylindrical body B.

[0012] Preferably, a motor A is provided inside the two outer extension sections on both sides, and the output end of the motor A is connected to both sides of the semi-cylindrical body B, which can control the lifting of the semi-cylindrical body B.

[0013] Preferably, the semi-cylindrical body B is coated with a plastic, and the plastic includes, but is not limited to, materials such as nitrile rubber and silicone rubber. The plastic has a certain elasticity, which can improve the clamping effect and effectively avoid the occurrence of metal debris due to direct contact with the semi-cylindrical body A.

[0014] Preferably, grooves are provided on both sides of the top of the semi-cylindrical body B to provide an installation position for the buckles. The two buckles are located inside the grooves, and the buckle (6) is sleeved outside the fixed shaft inside the groove.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. This traction mechanism does not require manual single-point flattening of the cloth by hand, has a higher operation efficiency, and greatly improves the flatness of the cloth surface and the uniformity of the overall tension, thereby improving the product yield.

[0017] 2. The clamping section of this mechanism is composed of two semi-cylinders with appropriate thickness, has a higher strength and is not easily deformed, solving the problem that the metal sheets of the clamping components in the prior art are prone to deformation after long-term use, resulting in uneven tension on the glass cloth surface, and at the same time improving the traction stability.

[0018] 3. Since the semi-cylindrical body B is coated with a plastic and has a certain elasticity, not only the clamping effect is better, but also the occurrence of metal debris due to direct contact with the semi-cylindrical body A can be effectively avoided.

[0019] 4. Through the mutual cooperation between the semi-cylinder A, semi-cylinder B and the connecting column, the length of the connecting column of this mechanism is appropriate. By cooperating with the motor A, the automatic adjustment of the gap between the semi-cylinder A and the semi-cylinder B can be realized. The adjustable range of the gap between the semi-cylinder A and the semi-cylinder B is large, and it can adapt to glass cloths of different thicknesses passing through. Even the thinner glass cloth with poor drapability can easily pass through without manual assistance for cloth threading. Further, by cooperating with the motor A, the automatic adjustment of the gap between the semi-cylinder A and the semi-cylinder B can be realized. Description of the Drawings

The two buckles 6 are located inside the grooves, and the buckles 6 are sleeved outside the fixed shafts inside the grooves. One end of the buckle 6 is fixed to the fixed shaft inside the groove, and the other end extends out of the semi-cylinder 5 and is suspended, so that when the buckle 6 is pulled, the semi-cylinder A and the semi-cylinder B 5 can be locked. A motor B 9 is provided on one side of the traction rod 1, and a bearing 10 is provided inside the extension section 2. The output end of the motor B 9 is connected to the bearing 10.

[0026] Further, guide holes that are slidably matched with the connecting column 7 are provided on both sides of the bottom of the semi-cylindrical body B5, enabling the semi-cylindrical body B5 to slide along the guidance of the connecting column 7 to adjust the distance between the semi-cylindrical body B5 and the semi-cylindrical body A4.

[0027] Further, the semi-cylindrical body A4 and the semi-cylindrical body B5 have the same thickness, both being 2 - 3 cm.

[0028] Further, the length of the connecting column 7 is 1.0 - 2.5 cm, preferably 1.5 - 2.5 cm, to control the adjustable range of the gap between the semi-cylindrical body A and the semi-cylindrical body B.

Then start the motor A8 to smoothly drive the semi-cylindrical body B5 to approach the semi-cylindrical body A4 to clamp the glass cloth. Flip the buckle 6 on the semi-cylindrical body B5 to lock the semi-cylindrical body B5 and the semi-cylindrical body A4. Then start the motor B9 to rotate the bearing 10 inside the extension segment 2, so that the traction rod 1 rotates to drive the glass cloth to wind around the semi-cylindrical body A and the semi-cylindrical body B, thereby adjusting the surface flatness and the overall tension uniformity of the glass cloth. Finally, drive the traction rod 1 to move through the transmission component on the frame to pull the glass cloth to the bonding table.
