Description

Technical Field

[0001] The utility model relates to the field of zipper production equipment, in particular to a bending tape shaping and drying device. Background Art

[0002] Zippers can be used on textile products such as clothing, luggage, tents, and home textiles. When sewing the zipper tape to the fabric, the zipper may produce bulges, arches, waves, etc., which affect the aesthetics of the textile products. When the zipper tape is in a curved arc shape, after sewing the zipper to the fabric, a flat and beautiful appearance will be formed. The existing technology for curved tapes is to use nylon filaments on one side of the tape, relying on the elastic contraction of the nylon filaments to form an inner arc. Or high heat shrinkage filaments are arranged inside the tape, or a fabric structure with high stiffness is used at the edge of the tape, etc. The curved zippers obtained by this structure are more costly than ordinary zippers. Summary of the Invention

[0003] In view of this, the purpose of the utility model is to provide a bending tape shaping and drying device, and the produced bending tape has a lower cost.

[0004] To achieve the above purpose, the solution of the utility model is:

[0005] A bending tape shaping and drying device includes a box body and a drying cylinder. The drying cylinder is arranged inside the box body. The drying cylinder has a cylinder body and a plurality of annular drying units arranged on the cylinder body. The plurality of annular drying units are arranged at intervals. The outer side surface of the annular drying unit has a first tape winding surface in the shape of a frustum of a cone. Let the included angle between the first tape winding surface and the axis of the drying cylinder be θ, and 22.1° < θ < 50°.

[0006] Furthermore, it further includes a roller group, and the roller group is arranged inside the box body.

[0007] Furthermore, the roller group is located on one side of the drying cylinder.

[0008] Furthermore, at least two rollers are arranged on the roller group.

[0009] Furthermore, the rollers on the roller group are arranged at intervals in the vertical direction.

[0010] Furthermore, the rotating shafts of the rollers on the roller group are all located in the same vertical plane.

[0011] Furthermore, a second tape winding surface is arranged along the outer circumference of the roller, and the second tape winding surface is in the shape of a frustum of a cone.

[0012] Furthermore, a heating device for heating the rollers is arranged on the roller group.

[0013] Further, the distance between two adjacent second belt winding surfaces is less than the minimum outer diameter of the second belt winding surface.

[0014] After adopting the above structure, a zipper proposed by the present utility model has the following technical effects: When the present utility model is in use, the belt is first wound around two drying cylinders in sequence and then around a plurality of rollers on the roller group. During the drying process, the drying cylinders and the rollers rotate in the same direction, causing the belt to continuously advance on the drying cylinders and the rollers. Since the first belt winding surface is a frustum of a cone, when the belt is wound around the annular drying unit for drying, the tensions on both sides of the belt by the first belt winding surface are different. Therefore, the contractions on both sides of the belt are inconsistent during the drying process, and the angle θ between the outer side surface of the annular drying unit and the axis of the cylinder body of the drying cylinder is in the range of 22.1° to 50°. The annular drying unit within this range can cause a large contraction difference on both sides of the belt, thereby causing a large bending arc on one side of the belt.

[0020] In order to further explain the technical solution of the present utility model, the present utility model will be elaborated in detail below through specific embodiments.

[0021] As Figure 1 shown, a bending belt shaping and drying device includes a box body 1, a roller group 2 and a drying cylinder 3. The drying cylinder 3 and the roller group 2 are both arranged in the box body 1. The roller group 2 is located on one side of the drying cylinder 3. In this embodiment, the number of drying cylinders 3 is two, and the two drying cylinders 3 can wind a longer belt to improve the drying efficiency. The number of roller groups 2 is one group.

[0022] Since both the drying cylinder 3 and the roller group 2 are arranged inside the box body 1, the heat loss generated during the drying and shaping of the cloth belt is relatively small. Compared with the existing structure where the drying cylinder is inside the box body and the roller group is outside the box body, this arrangement has the advantage of higher drying efficiency.

[0023] The drying cylinder 3 has a cylinder body 4 and a plurality of annular drying units 5 arranged on the cylinder body 4. The cylinder body 4 is cylindrical, and a first electric heating device (not shown in the figure) is arranged inside the cylinder body 4. The first electric heating device is an electric heating device that can be used on a drying cylinder in the conventional technology. The above-mentioned first electric heating device is used to raise the temperature of the drying cylinder and thereby dry the cloth belt wound around the drying cylinder 3. The plurality of annular drying units 5 are arranged at intervals. Preferably, in this embodiment, the plurality of annular drying units 5 are arranged at equal intervals. The outer side surface of each annular drying unit 5 has a first cloth belt winding surface 6 in the shape of a frustum of a cone. Let the included angle between the outer side surface of the first cloth belt winding surface 6 and the axis of the cylinder body 4 be θ, and 22.1° < θ < 50°. When using the drying cylinder 3, the cloth belt is wound around the first cloth belt winding surface 6 of the drying cylinder 3. Specifically, the cloth belt is arranged in a way that it is wound around the outer side surface of each annular drying unit in turn in circles. When the cloth belt to be dried is a cloth belt for a zipper, the cloth ribs of the above-mentioned cloth belt for a zipper are located at the gap between two adjacent annular drying units 5.

[0024] The roller group includes a bracket 7 and a number of rollers 8. Further, the roller 8 includes a wheel body and side walls 9 arranged on both sides of the wheel body. A second cloth belt winding surface 10 is arranged along the outer circumference of the wheel body, and the second cloth belt winding surface 10 is also in the shape of a frustum of a cone.

[0025] A number of rollers are installed on the bracket 7. The number of rollers 8 is more than two. In this embodiment, the number of rollers is five. The five rollers 8 are arranged at intervals in the vertical direction. The rotating shafts of the rollers on the roller group 2 are all located in the same vertical plane. The distance between two adjacent second cloth belt winding surfaces 10 is less than the minimum outer diameter of the second cloth belt winding surface 10. This arrangement enables the cloth belt to be tensioned between two adjacent rollers 8, achieving a better shaping effect.

[0026] Further, a second heating device for heating the roller 8 is arranged on the roller group 2. The above-mentioned second heating device uses a conventional electric heating device, and the second electric heating device is used to heat the roller 8.

[0027] When the utility model is in use, first wind the cloth belt around the two drying cylinders in sequence and then around multiple rollers on the roller set 2. During the drying process, the drying cylinder 3 and the roller 8 rotate in the same direction, so that the cloth belt continuously advances on the drying cylinder 3 and the roller 8. Since the outer side of the annular drying unit 5 is a conical surface, when the cloth belt is wound around the annular drying unit 5 for drying, the tensions on both sides of the cloth belt by the annular drying unit 5 in the shape of a conical surface are different. Therefore, the shrinkages on both sides of the cloth belt during drying are inconsistent. Moreover, the angle θ between the outer side of the first cloth belt winding surface 6 and the axis of the cylinder body of the drying cylinder 3 is within the range of 22.1° to 50°. The first cloth belt winding surface 6 within this range can cause a large shrinkage difference on both sides of the cloth belt, thereby causing a large bending arc on one side of the cloth belt. At the same time, after the cloth belt passes through the drying cylinder 3, it will continue to wind around the rollers on the roller set 2. Since the second cloth belt winding surface 10 of the roller 8 is also a conical surface and the roller 8 is provided with a second electric heating device, the cloth belt can be further shaped again on the bent side during the process of advancing on the roller set 2, thereby improving the stability of the bent side of the cloth belt.
