Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to an adjustable fabric edge pressing device. Background Technology

[0002] Fabric edge pressing is a process that treats the edges of fabric through heat pressing, sewing, or bonding. It is often used to prevent fabric edges from becoming loose, curled, or worn, while also improving the overall structural stability and aesthetics. For example, fiberglass edge pressing fixes the edges by covering them with resin or glue, enhancing tensile strength and preventing cracks.

[0003] The prior art discloses a fabric edge pressing device, including a correcting block with a first conveying cavity extending through it. A first T-shaped block is fixedly installed inside the first conveying cavity, and an infrared sensor is fixedly installed on the inner wall of the first T-shaped block, with the infrared sensor facing the corresponding first transmission component. An umbrella fabric strip is inserted through the gap between the first conveying cavity and the first T-shaped block, ensuring that the length of the edge of the umbrella fabric strip on the upper side of the first T-shaped block is approximately the same. By moving the two edges of the umbrella fabric strip on the upper side of the first T-shaped block towards each other, the umbrella fabric strip inside the first conveying cavity is tightened. The infrared sensor can detect the distance between the umbrella fabric strip and the infrared sensor. Through a telescopic structure, the two sets of first transmission components move laterally, driving the umbrella fabric strip to move laterally until the values ​​detected by the two infrared sensors are consistent, thus accurately determining the folding position of the edge of the umbrella fabric strip.

[0004] The aforementioned device cannot adjust the pressure of the flattening wheel on the fabric according to the fabric thickness.

[0005] Therefore, it is necessary to provide an adjustable fabric edge-pressing device to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to overcome the defects of the prior art, this utility model provides an adjustable fabric pressing device that can adjust the pressure of the pressing wheel on the fabric according to the thickness of the fabric.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0022] First embodiment:

[0023] like Figure 1-4 As shown, this utility model provides an adjustable fabric pressing device. Only the part of the device that contacts the fabric and performs the pressing function is shown in the figure. The structure of the rest is similar to the workbench of a sewing machine and is not shown. Its structure is consistent with the prior art. Overall, the structure shown in the figure includes three main parts: the structural base 20 and the pressure regulator 10 installed inside the structural base 20, and the connecting piece 30 located at the top that fixes the structural base 20 to the rest of the pressing machine.

[0024] Specifically, the structural base 20 includes a connecting base 21, the shape of which is as follows: Figure 2 As shown, the middle part is a cavity with an opening at the top and a through hole at the bottom for the sliding rod at the top of the movable seat 23 to pass through. Each of its two side walls has a first slide rail 211, which is a slot penetrating the side wall of the movable seat 23, with a sliding groove 212 formed on the slot wall. A mounting base 22 is bolted to the lower end of the connecting seat 21. The mounting base 22 is shaped as shown in the image. Figure 2 As shown, its side wall is also provided with a slotted second slide rail 221. The bottom of the second slide rail 221 is vertically fixedly installed with a first spring 222. The upper end of the first spring 222 supports the wheel axle 241 on which the pressure wheel 24 is fixedly installed. The same structure is also on the side wall of the connecting seat 21. The C-shaped movable seat 23 is installed on the wheel axle 241. At the same time, the wheel axle 241 is slidably installed in the slots on the connecting seat 21 and the mounting seat 22. The first spring 222 generates an upward elastic force on the wheel axle 241.

[0025] On the other hand, such as Figure 2-4 As shown, the core component of the pressure regulator 10 is a rotating shaft 11 rotatably mounted on a sliding seat 12. The shape of the sliding seat 12 is as follows: Figure 2As shown, the left and right parts are fixedly connected, and the slider 121 on it is adapted to the slide groove 212. Therefore, the sliding seat 12 can slide up and down along the slide groove 212 with the rotating shaft 11. A drive shaft 16 is rotatably mounted on the other side of the sliding seat 12. The first bevel gear 13 is fixed to one end of the right side of the drive shaft 16. Correspondingly, as shown... Figure 4 As shown, a second bevel gear 14 that meshes with the first bevel gear 13 is also fixed on the rotating shaft 11. The upper end of the rotating shaft 11 is a threaded section 111, which is installed in the threaded hole 31 in the connecting piece 30. The lower end of the rotating shaft 11 is inserted into the groove provided on the top slide rod of the movable seat 23. The two are rotatably connected. In use, the handwheel 161 is turned to drive the shaft 16 to rotate. The drive shaft 16 drives the first bevel gear 13 at its end to rotate, and at the same time, the first bevel gear 13 drives the second bevel gear 14. The second bevel gear 14 drives the rotating shaft 11 to rotate. Since the threaded section 111 of the rotating shaft 11 rotates in the threaded hole 31, the rotating shaft 11 causes the sliding seat 12 to slide downward along the first slide rail 211. Therefore, the lower end of the rotating shaft 11 applies pressure to the moving seat 23. The pressure is transmitted to the first spring 222 through the wheel axle 241. The first spring 222 is compressed after being pressed, and the pressing wheel 24 and the wheel axle 241 move downward. The distance between the pressing wheel 24 and the fabric below it is smaller, so the pressure is greater.

[0026] The pressure regulator 10 is used to adjust the position of the pressing wheel 24, thereby changing the gap between the pressing wheel 24 and the fabric. When the gap is small, the pressing wheel 24 applies greater pressure to the fabric. Therefore, the operator can flexibly adjust the appropriate pressure according to the actual fabric thickness.

[0027] Second embodiment:

[0028] like Figure 3-4 As shown, a second spring 15 is sleeved on the lower end of the rotating shaft 11. The lower end of the second spring 15 is placed on the circular pad 112 of the top slide rod of the movable seat 23. The connection between the upper end of the second spring 15 and the rotating shaft 11 is also the same structure. The second spring 15 is sandwiched between the two pads 112 on the rotating shaft 11 and the slide rod of the movable seat 23. In use, the handwheel 161 is rotated in the manner of the first embodiment. When the rotating shaft 11 moves downward, both the first spring 222 and the second spring 15 are compressed.

[0029] By setting a second spring 15, the amount of compression of the first spring 222 caused by the downward movement of the rotating shaft 11 can be reduced, thus achieving a more precise pressure adjustment effect.

[0030] Working principle: The drive shaft 16 drives the first bevel gear 13 at its end to rotate, and at the same time the first bevel gear 13 drives the second bevel gear 14 to rotate. The second bevel gear 14 drives the rotating shaft 11 to rotate. Since the threaded section 111 of the rotating shaft 11 rotates in the threaded hole 31, the rotating shaft 11 drives the sliding seat 12 to slide down along the first slide rail 211. Therefore, the lower end of the rotating shaft 11 applies pressure to the moving seat 23. The pressure is transmitted to the first spring 222 through the wheel axle 241. The first spring 222 is compressed after being pressed, and the pressing wheel 24 and the wheel axle 241 move down, making the gap between the pressing wheel 24 and the fabric below it smaller.

[0031] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
