Description

Technical Field

[0001] The utility model relates to the technical field of zipper tape processing equipment, in particular to a zipper pre-expanding machine. Background Art

[0002] Zipper pre-expanding machines are widely used in the clothing manufacturing industry, mainly for solving the problem of zipper arching and ensuring the quality and appearance of clothing. The working principle of the zipper pre-expanding machine is: the transmission rollers act on the upper and lower sides of the zipper tape to be processed respectively, and through differential transmission, the transmission roller assembly located in the front drives the zipper tape to move forward at a speed greater than the transmission roller assembly located in the rear. In addition, the heat setting device is located between the two adjacent sets of transmission roller assemblies, which is used to heat and set the zipper tape conveyed between the two adjacent sets of transmission roller assemblies. When the existing zipper pre-expanding machine is in use, the zipper tape is placed on the workbench plane, and the zipper tape is conveyed forward by the transmission action of the transmission roller. However, since the workbench does not limit the zipper tape, the zipper tape can easily deviate from the center of the transmission roller during the transmission process, thereby affecting the processing effect of the zipper tape.

[0014] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0015] Example: Please refer to Figure 1-2A zipper pre-expanding machine includes a workbench 1, a heat setting component and two sets of transmission components 2. The two sets of transmission components 2 are arranged in sequence along the transmission direction of the zipper tape. The transmission component 2 includes an upper roller 201 and a lower roller 202 arranged in an upper and lower interval. The workbench 1 is connected to a bracket 10 for mounting the upper roller 201 and the lower roller 202. The upper roller 201 and the lower roller 202 are both rotatably connected to the bracket 10. A first motor 11 and a second motor 12 are sequentially provided along the transmission direction of the zipper tape. The first motor 11 and the second motor 12 are respectively connected to the corresponding lower roller 202 for driving the lower roller 202 to rotate. The output shafts of the first motor 11 and the second motor 12 are both connected to a driving wheel. The upper roller 201 is connected to the There is a driven wheel, which is meshed with the driving wheel. Through the transmission action of the driving wheel and the driven wheel, the upper roller 201 and the corresponding lower roller 202 rotate synchronously; the interval between the upper roller 201 and the lower roller 202 is equal to the thickness of the zipper tape, and the feeding end of the workbench 1 is provided with a first limit baffle 4 and a second limit baffle 5 set at intervals. The interval between the first limit baffle 4 and the second limit baffle 5 is equal to the width of the zipper tape, and the interval is aligned with the center of the transmission component 2. The zipper tape is placed between the first limit baffle 4 and the second limit baffle 5. Under the limiting action of the first limit baffle 4 and the second limit baffle 5, the zipper tape is always in a straight line state, and the end of the zipper tape is first inserted into the nearest Between a group of upper rollers 201 and lower rollers 202, the zipper tape is conveyed forward under the mutual squeezing action of the upper rollers 201 and the lower rollers 202, and a material trough 3 adapted to the zipper tape is provided in the middle of the workbench 1. After the zipper tape is conveyed to the pre-expansion processing position, it continues to move forward in a straight line along the material trough 3 to ensure that the zipper tape is accurately moved from the front end to the processing position at the rear end; the middle parts of the upper rollers 201 and the lower rollers 202 are provided with grooves 8, and the chain teeth in the middle of the zipper tape are more protruding than the chain tape, and the width of the grooves 8 matches the protruding parts of the chain teeth, so that the upper rollers 201 and the lower rollers 202 are more in line with the structure of the zipper tape; the surfaces of the upper rollers 201 and the lower rollers 202 are provided with anti-slip grooves. The speed of the first motor 11 is less than that of the second The rotation speed of the motor 12 causes the front transmission assembly 2 and the rear transmission assembly 2 to produce a speed difference, thereby performing pre-expansion processing on the zipper tape; the heat setting assembly is arranged between the two groups of transmission assemblies 2, and the zipper tape is heated and set by the heat setting assembly. Specifically, the heat setting assembly includes two groups of hot steam nozzles 9, and the two groups of hot steam nozzles 9 are symmetrically arranged up and down.
