Description

Technical Field

[0001] This utility model belongs to the technical field of garment processing equipment, specifically a raincoat hem heat sealing device. Background Technology

[0002] In the production of raincoats, edge-flanging and heat sealing are crucial processes that directly affect the product's sealing performance and appearance quality. Currently, some edge-flanging and heat-sealing equipment based on mechanical pressing or heat fusion technologies exists on the market. However, these devices typically require complex structural designs to achieve simultaneous edge-flanging and heat sealing, and they have poor adaptability to raincoat fabrics of varying thicknesses and materials. Furthermore, existing equipment often relies on manual adjustments during the heat sealing process, resulting in low efficiency and difficulty in ensuring consistency.

[0003] CN110839996B discloses a flanging heat-sealing device for raincoat production, belonging to the technical field of flanging heat-sealing devices. The device involves placing raincoat fabric on top of a raincoat fabric inlet plate, starting a drive motor to rotate a rotating shaft, which in turn rotates a rotating disk. The rotating disk then drives a hinged push rod to push a sliding limit plate downwards. The sliding limit plate causes a toothed block to rotate a rubber rack, which in turn rotates a second gear disk and a first gear disk, thus pushing the raincoat fabric into a rotating roller. The raincoat fabric is pushed into the flanging assembly side by an L-shaped flanging rod on the downward-moving sliding limit plate, which presses the flanging assembly to achieve flanging of the raincoat fabric. The flanged edge is then heated and formed by a thermoforming pressing assembly, thus realizing an integrated automatic feeding, flanging, and heat-pressing operation. This method is convenient to operate and highly efficient.

[0004] For example, in actual production, some flanging heat-sealing devices complete the operation through the cooperation of multiple sets of rollers and heating modules. However, due to their relatively fixed structural design, frequent mold changes or recalibration of equipment parameters are required when dealing with raincoats of different specifications. This limitation not only increases the difficulty of operating the equipment but also extends the production cycle. The above problems indicate that there is room for improvement in the flexibility and efficiency of existing technologies.

[0005] Therefore, we have made improvements to this by proposing a raincoat edge-folding heat-sealing device. Utility Model Content

[0025] This utility model relates to a heat-sealing device for the hem of a raincoat, the specific implementation of which is described in conjunction with the attached drawing. Figure 1 To be continued Figure 4 Please provide a detailed explanation. For example... Figure 1 As shown, the device includes a heat-sealing structure 1 and a flanging auxiliary structure 2. The heat-sealing structure 1 and the flanging auxiliary structure 2 work together to complete the flanging and heat-sealing operation of the raincoat fabric. The heat-sealing structure 1 includes a heating plate 3, a heat-conducting column 4, a pressing plate 5, an elastic connecting rod 6, and a buffer spring 7. The flanging auxiliary structure 2 includes a flanging roller 8, a support frame 11, a sliding support 12, and a guide. The specific connection relationship, positional relationship, and mutual cooperation of each component are as follows.

[0026] The heat-sealing structure 1 is the core component of the device. Its heating plate 3 is bolted to the top of the outer shell of the heat-sealing structure 1. Multiple heat-conducting holes are evenly distributed on the surface of the heating plate 3, and a heat-conducting column 4 is embedded inside each hole. The end of the heat-conducting column 4 protrudes from the lower surface of the heating plate 3 and contacts the fabric to be processed. The heat-conducting column 4 is made of a high thermal conductivity material, and its length is slightly greater than the thickness of the heating plate 3, ensuring efficient heat transfer to the fabric surface. The pressing plate 5 is located below the heating plate 3, and the two are connected by four elastic connecting rods 6, evenly distributed at the four corners of the pressing plate 5. Each elastic connecting rod 6 is fitted with an independent buffer spring 7, with both ends welded to the pressing plate 5 and the heating plate 3, respectively. The initial length of the buffer spring 7 is 10mm, and the compression range is 2-8mm. When the pressing plate 5 is subjected to external force, the elastic connecting rods 6 and the buffer springs 7 work together to automatically adjust the pressure distribution according to the fabric thickness, thereby achieving uniform pressing.

[0027] A temperature sensor is installed on the top of the heating plate 3. The output of the temperature sensor is electrically connected to the controller via a signal line. The output of the controller is electrically connected to the heating element of the heating plate 3 for real-time monitoring and adjustment of the temperature of the heating plate 3. A pressure sensor is installed on the bottom of the pressing plate 5. The output of the pressure sensor is also electrically connected to the controller via a signal line for detecting the contact pressure between the pressing plate 5 and the fabric. The distance between the heating plate 3 and the pressing plate 5 can be adjusted by an adjusting component, which includes an adjusting screw 20. The top end of the adjusting screw 20 passes through the outer shell of the heat-sealing structure 1 and is threaded to the outer shell. The bottom end of the adjusting screw 20 is fixedly connected to the top of the heating plate 3 via a ball joint. When the adjusting screw 20 is rotated, the heating plate 3 moves up and down in the vertical direction, thereby adjusting the distance between it and the pressing plate 5 to accommodate fabrics of different thicknesses.

[0028] The flanging auxiliary structure 2 is located on one side of the heat-sealing structure 1. Its core component is the flanging roller 8. The outer circumferential surface of the flanging roller 8 is provided with several elastic protrusions 9, and a receiving groove 10 is formed between two adjacent elastic protrusions 9. The receiving groove 10 is used to guide the edge of the fabric into the flanging state. The two ends of the flanging roller 8 are rotatably connected to the support frame 11 through bearings, and the support frame 11 is fixed on the sliding support member 12. The sliding support member 12 slides along the inner wall of the guide member to adjust the position of the flanging roller 8. The guide member includes a guide frame 13, and the inner wall of the guide frame 13 is provided with a groove 14. The groove 14 has a T-shaped cross section. The sliding support member 12 includes a slider 15. The outer circumferential surface of the slider 15 is provided with a flange that matches the groove 14. The slider 15 is slidably connected to the groove 14 through the flange. The bottom of the slider 15 is provided with a return spring 16. The other end of the return spring 16 is fixedly connected to the bottom of the guide frame 13. The return spring 16 provides elastic force to keep the slider 15 in its initial position when it is not subjected to external force. The top of the guide frame 13 is provided with a locking bolt. The end of the locking bolt passes through the guide frame 13 and abuts against the top of the slider 15. When the slider 15 is adjusted to a suitable position, the slider 15 is fixed in the guide frame 13 by tightening the locking bolt.

[0029] The flanging roller 8 has positioning rings 18 at both ends, and anti-slip pads 19 are provided on the inner side of the positioning rings 18. The anti-slip pads 19 are in close contact with the outer circumferential surface of the flanging roller 8 to prevent the fabric from shifting during the flanging process. A cooling channel 17 is provided at the axis of the flanging roller 8. The two ends of the cooling channel 17 are connected to an external cooling system for rapid cooling of the fabric after heat sealing. The cross-section of the cooling channel 17 is circular, and the inner wall of the channel is smooth to reduce the resistance when the cooling medium flows. The flanging roller 8 is connected to a sliding support 12 through a support frame 11. The sliding support 12 slides along the inner wall of the guide, so that the position of the flanging roller 8 can be flexibly adjusted according to the fabric specifications.

[0030] In actual operation, the raincoat fabric to be processed is first placed on one side of the flanging auxiliary structure 2, and the edge of the fabric is guided into the receiving groove 10 of the flanging roller 8. As the flanging roller 8 rotates, the elastic protrusion 9 cooperates with the receiving groove 10, gradually rolling up the edge of the fabric to form a flanged state. After the flanging is completed, the fabric is sent into the working area of ​​the heat sealing structure 1. The heating plate 3 transfers heat to the surface of the fabric through the heat-conducting column 4, and the pressing plate 5 applies uniform pressure to the fabric under the action of the elastic connecting rod 6 and the buffer spring 7, thereby completing the heat sealing operation. During this process, the temperature sensor and the pressure sensor monitor the temperature of the heating plate 3 and the pressure of the pressing plate 5, respectively, and transmit the data to the controller. The controller automatically adjusts the heating power of the heating plate 3 and the pressure value of the pressing plate 5 according to the preset parameters to ensure stable heat sealing quality.

[0031] When processing fabrics of different specifications or thicknesses, the distance between the heating plate 3 and the pressing plate 5 can be adjusted by adjusting the screw 20. Simultaneously, the position of the flanging roller 8 can be adjusted by sliding the sliding support 12 along the inner wall of the guide to ensure optimal fit with the fabric edge. After adjustment, tighten the locking bolt to fix the slider 15, ensuring the flanging roller 8 remains stable during operation. The cooling medium in the cooling channel 17 rapidly cools the fabric after heat sealing, preventing deformation or damage due to high temperatures.

[0032] The above-described embodiments detail the structural composition and operating principle of the raincoat hemming heat sealing device. The connection relationships, positional relationships, and mutual cooperation methods between the various components have been clearly explained, ensuring that those skilled in the art can implement the technical solution based on the contents of the specification.

[0033] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the operating principle and implementation steps of the raincoat hemming heat sealing device is provided in conjunction with specific application scenarios.

[0034] First, the raincoat fabric to be processed is placed on one side of the flanging auxiliary structure 2, ensuring that the edge of the fabric is guided into the receiving groove 10 of the flanging roller 8. The outer circumferential surface of the flanging roller 8 is provided with several elastic protrusions 9, with receiving grooves 10 formed between adjacent elastic protrusions 9. The design of these receiving grooves 10 allows the fabric edge to be stably introduced into the flanging state. When the flanging roller 8 rotates on the sliding support 12 via the support frame 11, the elastic protrusions 9 and the receiving grooves 10 work together to gradually roll up the fabric edge and complete the flanging operation. During this process, the positioning rings 18 and anti-slip pads 19 at both ends of the flanging roller 8 are tightly fitted to the fabric surface to prevent the fabric from shifting or slipping during the flanging process, thereby ensuring the stability of the flanging effect.

[0035] Subsequently, the hemmed fabric is fed into the working area of ​​the heat-sealing structure 1. The heating plate 3 transfers heat to the fabric surface through evenly distributed heat-conducting columns 4. These columns, made of highly thermally conductive material, have ends that directly contact the fabric, ensuring efficient and even heat transfer to the heat-sealing area. Simultaneously, the pressing plate 5 applies appropriate pressure to the fabric under the action of elastic connecting rods 6 and buffer springs 7. Four elastic connecting rods 6 are evenly distributed at the four corners of the pressing plate 5. Each elastic connecting rod 6 is externally fitted with a buffer spring 7 that automatically adjusts the compression amount according to the fabric thickness, allowing the pressing plate 5 to adapt to fabrics of different thicknesses and provide a uniform pressure distribution. This design effectively avoids poor heat sealing caused by uneven pressure.

[0036] During the heat sealing process, a temperature sensor monitors the temperature of the heating plate 3 in real time and transmits the collected data to the controller. The controller automatically adjusts the heating power of the heating plate 3 according to preset parameters to ensure that the temperature remains within the set range during the heat sealing process. Simultaneously, a pressure sensor at the bottom of the pressing plate 5 detects the contact pressure between the pressing plate 5 and the fabric and feeds the data back to the controller. The controller dynamically adjusts the pressure value of the pressing plate 5 based on the feedback information from the pressure sensor, thereby ensuring the stability of the heat sealing quality. This automated monitoring and adjustment mechanism significantly reduces the need for manual intervention and improves production efficiency and consistency.

[0037] When processing fabrics of different specifications or thicknesses, the distance between the heating plate 3 and the pressing plate 5 can be adjusted by adjusting the screw 20. Specifically, rotating the adjusting screw 20 causes its bottom end to push the heating plate 3 vertically up and down through the ball joint, thus changing the distance between the heating plate 3 and the pressing plate 5. Furthermore, the position of the flanging roller 8 can also be flexibly adjusted according to the fabric specifications. The sliding support 12 slides along the inner wall of the guide frame 13, and the slider 15 engages with the T-shaped groove 14 inside the guide frame 13 through its outer flange, ensuring a smooth and precise sliding process. After the slider 15 is adjusted to the appropriate position, it is fixed by tightening the locking bolt to ensure the stability of the flanging roller 8 during operation. The return spring 16 provides elasticity when no external force is applied, allowing the slider 15 to quickly return to its initial position, facilitating subsequent adjustments.

[0038] After heat sealing, the cooling medium in cooling channel 17 rapidly cools the fabric. The circular cross-section and smooth inner wall of cooling channel 17 effectively reduce resistance to the flow of the cooling medium, thereby improving cooling efficiency. This rapid cooling mechanism not only prevents fabric deformation or damage due to high temperatures but also shortens the overall production cycle.

[0039] In summary, this invention achieves efficient flanging and heat sealing of raincoat fabric through the synergistic effect of the flanging auxiliary structure 2 and the heat-sealing structure 1. The connection relationships, positional relationships, and mutual cooperation methods between the various components have been clearly explained, ensuring that those skilled in the art can implement this technical solution based on the description.
