Description

Technical Field

[0001] The utility model relates to the field of carpet production, in particular to a constant tension conveying device for a carpet base fabric. Background Art

[0002] Carpet is a floor covering made of natural fibers such as cotton, linen, wool, silk, grass yarn, or chemical synthetic fibers, which is knitted, planted, or woven by hand or mechanical processes. It has the effects of reducing noise, heat insulation, and decoration, improving foot feel, preventing slips, and preventing air pollution. In the prior art, the carpet base fabric is usually rolled on a base fabric roller. In the production process of the carpet, the carpet base fabric on the base fabric shaft needs to be pulled out first, and then the carpet base fabric is transported to the carpet production equipment.

[0003] Since the carpet backing is wound on the material shaft, different layers are subjected to different tensile forces. Different layers of backing generate different tensions when being conveyed to the production equipment, which affects the quality of carpet production. Therefore, it is necessary to design a constant tension conveying device for the carpet backing to ensure constant conveying tension of the carpet backing and ensure the production quality of the carpet. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a constant tension conveying device for a carpet base fabric to solve the technical problem of inconvenient water absorption.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a constant tension conveying device for a carpet base fabric, comprising two mounting frames, each of which is provided with a limiting groove on one side of the two mounting frames, a trigger is fixedly installed on the upper side wall of the limiting groove, a moving block is slidably arranged in the limiting groove, a moving shaft is installed between the two moving blocks, a first guide shaft and a second guide shaft are installed between the two mounting frames, and the first guide shaft and the second guide shaft are both located above the moving shaft, a placing rack is installed on the two mounting frames, a material shaft is placed on the two placing racks, and a processing device is arranged on one side of the second guide shaft.

[0006] Furthermore, a buffer is fixedly mounted on the lower end side wall in the limiting groove, and a rubber pad is fixedly mounted on the buffer.

[0007] By adopting the above technical solution, the buffer and the rubber pad can prevent the moving shaft from being damaged due to a sudden drop and collision after the base cloth of the material shaft is used up.

[0008] Furthermore, an electric control box is fixedly mounted on one side of one of the mounting frames.

[0009] Furthermore, the upper end of the moving block is arranged in an arc surface.

[0010] In summary, the utility model mainly has the following beneficial effects:

[0011] The present application sets a movable shaft between two guide shafts and utilizes the principle of a movable pulley to ensure that the pulling force exerted by the production equipment on the base fabric is the same as the pulling force exerted on the base fabric on the material shaft, thereby ensuring that the tension of base fabrics of different layers on the material shaft is consistent when entering the production equipment, thereby avoiding affecting the quality of carpet production due to different tensions of the base fabrics.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0017] The following describes an embodiment of the utility model based on its overall structure.

[0018] A carpet base fabric constant tension conveying device, such as Figure 1 , Figure 2 , Figure 3As shown, it includes two mounting frames 3, and limiting grooves 5 are arranged on opposite sides of the two mounting frames 3. A trigger 9 is fixedly installed on the upper side wall of the limiting groove 5, and a moving block 10 is slidably arranged in the limiting groove 5. A moving shaft 6 is installed between the two moving blocks 10. The moving shaft 6 uses the principle of a movable pulley to make the tension on the base fabric on the material shaft 2 consistent, so that the tension on the base fabric is the same, thereby improving the production quality of the carpet. A first guide shaft 4 and a second guide shaft 7 are installed between the two mounting frames 3, and the first guide shaft 4 and the second guide shaft 7 are both located above the moving shaft 6. The two guide shafts use the principle of a fixed pulley to change the conveying direction of the base fabric. A placement rack 1 is installed, and a material shaft 2 is placed on two placement racks 3. The material shaft 2 is placed on the placement rack 1, which is convenient for quickly replacing the base cloth on the material shaft 2 after use. A processing device 13 is arranged on one side of the second guide shaft 7. An electric control box 8 is fixedly installed on one side of one of the mounting racks 3. The electric control box 8 is internally provided with various control circuits, so that a signal can be transmitted to the processing device 13 when the trigger 9 is triggered to reduce the transmission speed. The upper end of the moving block 10 is arranged in an arc surface to avoid the suction generated by the two planes of the moving block 10 and the trigger 9 fitting together. The suction will have a certain impact on the trigger 9 if used for a long time, thereby improving the service life of the trigger 9.

[0019] In some other embodiments, a buffer 12 is fixedly installed on the lower end side wall of the limiting groove 5, and a rubber pad 11 is fixedly installed on the buffer 12. The buffer 12 and the rubber pad 11 can prevent the moving shaft 6 from suddenly falling and colliding and causing damage after the base cloth of the material shaft 2 is used up.

[0020] The implementation principle of this embodiment is as follows: the base fabric on the material shaft 2 passes through the first guide shaft 4, the moving shaft 6 and the second guide shaft 7 in sequence so that the base fabric enters the processing device 13. When the base fabric starts to be processed and produced, the processing device 13 generates a pulling force to pull the base fabric, and the moving shaft 6 applies gravity to the base fabric, so that the pulling force on the base fabric on the material shaft 2 is consistent with the pulling force of the processing device 13 and is in the same state of magnitude, so that the tension on the entire base fabric is the same, thereby improving the quality of carpet production. When the moving shaft 6 rises to a certain height, the moving block 10 will touch the trigger 9, thereby reducing the base fabric conveying speed and causing the moving shaft 6 to drop and maintain balance. The buffer 12 and the rubber pad 11 can prevent the moving shaft 6 from suddenly dropping and colliding after the base fabric of the material shaft 2 is used up, causing damage.

[0021] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
