Description

Technical Field

[0001] The utility model relates to the technical field of zipper production feeding, and more specifically to a feeding machine with adjustable tension. Background Art

[0002] A zipper tape is a strip of material used to secure a zipper, usually on clothing to connect the two ends of a zipper.

[0003] In the process of zipper tape production, post-processing and shearing are often required. In this process, a feeding device is required. The feeding device refers to the equipment used to produce zipper tapes. It is mainly used to feed the zipper tapes into the machine for processing and production. It usually includes a fixing device, a traction roller, a driving device and a limiting guide device, which can facilitate the transportation of the zipper tape so that it can meet the needs of post-processing equipment for rack installation or cross-cutting of the zipper tape.

[0004] The existing zipper tape production feeder still has the following problems: the existing zipper tape production feeder often causes excessive relaxation or tension during the processing and feeding process due to uneven quality or unstable elasticity of the zipper tape material during the feeding process. The tension of the zipper tape may also be unstable due to too fast or too slow conveying speed, which will undoubtedly affect the stability of the zipper tape during feeding. In addition, the existing feeding method also mostly uses conveying rollers for conveying. The friction of the conveying rollers used in the existing zipper tape production is poor, which causes the zipper tape to slip easily during conveying, resulting in poor stability during feeding.

[0005] Moreover, during the processing and feeding of the zipper tape, the zipper tape often needs to be installed with a rack and cut. However, in actual processing, the surface of the zipper tape is often uneven, wrinkled and deformed due to improper winding operation during the early longitudinal cutting or the material itself. This can easily affect the processing accuracy of the zipper tape installation rack and cross-cutting in the later stage, causing great trouble to actual use.

[0006] In view of this, we propose a feeder with adjustable tension. Utility Model Content

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the utility model has the following advantages: when it is necessary to feed the zipper tape, the screw motor can be used to drive multiple limit baffles to guide and adjust the zipper tape according to its width. When it is found that the zipper tape is too loose, the zipper tape will sag. When it sags, the sensor can sense that the zipper tape is too loose. At this time, the first rotary motor will stop rotating to feed, and the second rotary motor will drive the feed roller to rotate, so that the loose zipper tape can be better fed to avoid excessive looseness during feeding. When the zipper tape is too tight, the zipper tape will The second rotating roller is driven to rise, and the connecting rod will touch the pressure sensor at this time. At this time, the rotating motor 1 and the rotating motor 2 will speed up the rotation, so as to better feed the zipper belt and avoid the zipper belt being too tight. In addition, the anti-skid roller can be used to increase the friction during feeding, so as to make the tension more stable, which is conducive to the smooth progress of the production process, reduce the slippage between the zipper belt and the conveying roller, and ensure the stability of the conveying process. If the anti-skid roller is excessively worn during long-term use, the threaded rod can be directly rotated to release its limit, which is more convenient for later replacement and has better overall practicality.

[0019] During the feeding process of the zipper tape, the traction heating roller can be used to flatten the zipper tape, and then the zipper tape can be cooled and shaped through the gap between the semiconductor refrigeration plate one and the semiconductor refrigeration plate two. The traction heating roller can soften the zipper tape, making it easier to flatten, and the cooling and shaping can fix the shape of the zipper tape, ensuring a more stable flattening effect, increasing the stability and dimensional accuracy of the zipper tape in later processing, and avoiding the processing yield of the zipper tape affected by wrinkles or deformation.

[0028] See also Figure 1-4 , the utility model provides a technical solution:

[0029] A feeder with adjustable tension, comprising a fixed seat 100, a mounting plate 110 is arranged on the front and rear outer walls of the fixed seat 100, a rotating motor 120 is arranged inside the fixed seat 100, and a solid material device 130 is connected to the output end of the rotating motor 120;

[0030] In some embodiments, the material fixing device 130 generally includes an inflatable shaft to facilitate fixing the zipper tape roll.

[0031] The front outer wall of the fixing seat 100 is provided with a temperature controller 140 and a tension controller 150;

[0032] In some embodiments: the temperature controller 140 is mainly used to control the temperature of the traction heating roller 220, the semiconductor refrigeration plate 215 and the semiconductor refrigeration plate 250, so that it can be more convenient to iron the zipper tape and facilitate later processing. An electric heating tube is arranged inside the heating roller 220 to heat it so that it can soften the zipper tape. The above belongs to the prior art.

[0033] A support plate 200 is disposed on the top of the fixing seat 100, a fixing plate 210 is disposed on the outer wall behind the support plate 200, an electric lifting rod 211 is disposed on the top of the fixing plate 210, and a connecting plate 212 is connected to the output end of the electric lifting rod 211;

[0034] It is convenient to compact, convey and flatten zipper tapes of various thicknesses;

[0035] The front outer wall of the support plate 200 is rotatably connected to a traction heating roller 220, and the front outer wall of the support plate 200 is also provided with a semiconductor refrigeration plate 250, a fixing box 230 and an installation box 310. The front outer wall of the support plate 200 is also provided with a movable groove 240 and a through movable groove matching the connecting plate 212. The movable groove 240 is slidably connected to a sliding block 241, and a pressure sensor 245 is provided at the bottom of the inner cavity of the movable groove 240. A screw motor 300 is provided inside the support plate 200.

[0036] Specifically, a second rotating motor 213 is disposed inside the connecting plate 212 , and a feeding roller 214 is connected to the output end of the second rotating motor 213 to facilitate feeding and conveying the zipper tape.

[0037] Furthermore, the outer wall of the feed roller 214 is clamped with an anti-skid roller sleeve 216, the inner wall of the anti-skid roller sleeve 216 is provided with a support frame 217, the outer wall in front of the support frame 217 is threadedly connected with a threaded rod 218, and the inner wall of the anti-skid roller sleeve 216 is also connected with a guide block 219, so as to conveniently use the anti-skid roller sleeve 216 to increase friction during feeding and avoid slippage during feeding.

[0038] Furthermore, a threaded groove matching the threaded rod 218 is provided in front of the feed roller 214, a guide groove matching the guide block 219 is opened on the circumferential outer wall of the feed roller 214, and a semiconductor refrigeration plate 215 is also provided on the outer wall in front of the connecting plate 212. The semiconductor refrigeration plate 250 and the semiconductor refrigeration plate 215 are both electrically connected to the temperature controller 140.

[0039] In some embodiments: the semiconductor refrigeration plate is composed of two different types of semiconductor materials, usually a P-type semiconductor and an N-type semiconductor, which form a thermopile through the thermocouple effect. When current passes through the thermopile, a heat difference is generated between the two semiconductors, thereby achieving a cooling effect. The heating end is usually provided with a heat sink to better dissipate heat, which is convenient for cooling and shaping the zipper tape after heating and plasticization, and is convenient for later processing. The semiconductor refrigeration plate 1 215 and the semiconductor refrigeration plate 2 250 do not contact the zipper tape to avoid affecting its feeding.

[0040] Furthermore, a rotating roller 231 is rotatably connected to the inner wall of the fixed box 230 , and a plurality of sensors 232 are disposed on the side wall of the fixed box 230 .

[0041] In some embodiments: the sensor 232 may optionally include a photoelectric sensor, which senses the sagging state by detecting the obstruction between the zipper tape and the sensor 232. When the zipper tape sags, the light emitted by the sensor will be blocked, thereby triggering a signal, wherein the sensor 232, the pressure sensor 245, the rotating motor 120 and the rotating motor 213 are all electrically connected to the tension controller 150, and the tension controller controls the driving of the rotating motor 120 and the rotating motor 213 according to the signals emitted by the sensor 232 and the pressure sensor 245.

[0042] It is worth noting that the side wall of the sliding block 241 is rotatably connected to a rotating roller 242, and a connecting rod 244 and a spring 243 are provided on the top of the sliding block 241. The end of the spring 243 is connected to the top of the moving groove 240, which is convenient for detecting the tension of the zipper belt when feeding.

[0043] In some embodiments, the gap between rotating roller 1 231 and rotating roller 2 242 is lower than the gap between semiconductor refrigeration plate 2 250 and semiconductor refrigeration plate 1 215, so that when the zipper tape is tight, driving roller 2 242 can be driven to rise and trigger the pressure sensor. When the zipper tape is too loose, the zipper tape will sag and block sensor 232 and be triggered.

[0044] It is worth noting that a screw is connected to the output end of the screw motor 300, the end of the screw extends to the inside of the installation box 310, and the outer wall of the screw is sleeved with a limit baffle 320. The outer wall of the limit baffle 320 is provided with multiple through grooves to facilitate guide adjustment according to the width of the zipper tape.

[0045] In some embodiments: the device can use an external conventional power supply for power supply. Secondly, a transmission roller can be set on the right side of the fixed seat 100 to facilitate the transportation of the zipper tape to subsequent processing equipment.

[0046] In addition, the circuits, electronic components and modules involved in the utility model are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to the internal structure and methods.

[0047] Working principle: First, when it is necessary to feed the zipper tape, the screw motor 300 can be used to drive multiple limit baffles 320 to guide and adjust the zipper tape according to its width. When the zipper tape is found to be too loose, the zipper tape will sag. When it is drooping, the sensor 232 can sense that the zipper tape is too loose. At this time, the rotating motor 120 will stop rotating to prompt the solid material device to stop feeding. After that, the rotating motor 213 can be controlled to drive the feed roller 214 to rotate, so that it can better feed the loose zipper tape to avoid excessive relaxation during feeding. When the zipper tape is too tight, the zipper tape will drive the rotating roller 242 to rise. At this time, the connecting rod 244 will touch the pressure sensor 245. At this time, the rotating motor 120 and the rotating motor 213 will speed up the rotation to better feed the zipper tape to avoid excessive tension of the zipper tape. In addition, the anti-slip roller 2 16 increases the friction during feeding, thereby making the tension more stable, which is conducive to the smooth progress of the production process, reduces the slippage between the zipper belt and the conveying roller 214, and ensures the stability of the conveying process. During long-term use, if the anti-slip sleeve roller 216 is excessively worn, the threaded rod 218 can be directly rotated to release its limit, which is more convenient for later replacement and has better overall practicality. During the feeding process of the zipper belt, the traction heating roller 220 can be used to flatten the zipper belt, and then the zipper belt can be cooled and shaped through the gap between the semiconductor refrigeration plate 1 215 and the semiconductor refrigeration plate 2 250. The traction heating roller 220 can soften the zipper belt, making it easier to flatten, and the cooling and shaping can fix the shape of the zipper belt, ensuring that the flattening effect is more stable, increasing the stability and dimensional accuracy of the zipper belt in later processing, and avoiding the processing yield of the zipper belt affected by wrinkles or deformation.

[0048] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
