Description

Technical Field

[0001] This utility model relates to the field of textile fabric processing technology, specifically to a thin composite fabric edge pressing device. Background Technology

[0002] Textile machinery refers to the various mechanical equipment needed to process natural or chemical fibers into textiles. While machinery for producing chemical fibers encompasses various chemical processing machines, it is now considered an extension of textile machinery and falls under a broader definition. The processes required to process different fibers such as cotton, linen, silk, and wool into textiles vary, and some are entirely different, necessitating a wide variety of machines. During fabric processing, edge pressing is necessary. Edge pressing devices are commonly used equipment in textile fabric processing to perform edge pressing on textile fabrics.

[0003] Existing fabric processing edge pressing equipment relies solely on the friction between the edge pressing roller and the fabric to flatten it. This method has limited friction and flattening effects on lightweight fabrics such as silk and chiffon. Furthermore, if the fabric edge itself is curled (such as the curled edge of knitted fabric), this horizontal rolling is unlikely to flatten it completely. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a thin composite fabric edge pressing device.

[0005] The technical solution of this utility model is: a lightweight composite fabric edge pressing device, including an operating table, two side plates disposed on the operating table, a mounting frame slidably disposed between the two side plates in a vertical direction, and an edge pressing roller assembly; the edge pressing roller assembly includes a connecting frame slidably disposed on the mounting frame in a horizontal direction, a hollow roller body fixedly connected to the connecting frame, a cam disposed inside the hollow roller body and rotatably connected to the connecting frame, an arc-shaped airbag disposed on the inner wall of the hollow roller body, and a drive unit disposed on the connecting frame for driving the cam to rotate; the side wall of the hollow roller body is provided with a plurality of air holes that contact the fabric, the air outlet of the arc-shaped airbag is connected to the air holes through a pipe, and the air inlet of the arc-shaped airbag is provided with a one-way valve; the arc-shaped airbag is made of polyurethane elastomer.

[0006] Furthermore, the arc-shaped airbag is provided with 3-5 air holes, and the air holes are all connected to the air outlet of each arc-shaped airbag through pipes; Explanation: By setting multiple arc-shaped airbags, the cam can trigger the compression of the arc-shaped airbags multiple times during one rotation, effectively increasing the air output frequency of the air holes, thereby increasing the frequency of flattening the fabric surface. Then, the edge pressing roller is used to roll laterally, further enhancing the flattening effect on thin fabrics, thus improving the edge pressing efficiency.

[0007] Furthermore, the side plate has a guide rail for sliding the mounting bracket; the drive unit includes a rack horizontally arranged on the mounting bracket, a gear rotatably arranged on the connecting bracket and meshing with the rack, and a transmission belt for connecting the gear with the cam belt; it is understood that the rotation of the gear can be achieved manually or by an electric push rod to push the gear forward to achieve its own rotation. Explanation: By utilizing the meshing action of gears and racks, the gears rotate, which in turn drives the cam to rotate, thereby achieving intermittent compression of the arc-shaped airbag. Compared to the original solution, which required separate motors for the horizontal sliding of the connecting frame and the rotation of the cam, the above method can effectively reduce the amount of motors used and lower costs.

[0008] Furthermore, the four corners of the operating table are provided with rotatable bending limiting members, and the bottom of the bending limiting members has a buffer pad; Note: The above settings can fix the unfolded fabric with the limiting component after one edge pressing is completed. Multiple layers of fabric can be pressed sequentially. The bottom cushioning pad can reduce wear on thin fabrics.

[0009] Furthermore, a filter screen is provided inside the air pores; Note: The filter screen can filter the gas blown onto the fabric, preventing impurities in the gas from falling onto the surface of the composite fabric.

[0010] The beneficial effects of this utility model are as follows: This utility model drives the cam to rotate through the drive unit. The convex angle of the cam periodically squeezes the arc-shaped airbag. The arc-shaped airbag is intermittently compressed and sprayed onto the fabric. After the convex angle rotates, the arc-shaped airbag recovers under its own elasticity. By opening the one-way valve, air is drawn into the arc-shaped airbag. During the movement of the edge pressing roller assembly, air is continuously sprayed and drawn in. The airflow impact flattens the fabric in advance, and then the edge is pressed. It has a better flattening effect on thin fabrics. Attached Figure Description

Detailed Implementation

[0012] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0013] Example 1: As Figures 1-2 The thin composite fabric edge pressing device shown includes an operating table 1, two side plates 2 disposed on the operating table 1, a mounting frame 3 slidably disposed between the two side plates 2 in a vertical direction, and an edge pressing roller assembly 4. The edge pressing roller assembly 4 includes a connecting frame slidably disposed on the mounting frame 3 in a horizontal direction, a hollow roller body 41 fixedly connected to the connecting frame, a cam 43 disposed inside the hollow roller body 41 and rotatably connected to the connecting frame, an arc-shaped airbag 42 disposed on the inner wall of the hollow roller body 41, and a drive unit disposed on the connecting frame for driving the cam 43 to rotate. The side wall of the hollow roller body 41 is provided with a plurality of air holes 40 that contact the fabric. The air outlet of the arc-shaped airbag 42 is connected to the air holes 40 through a pipe, and the air inlet of the arc-shaped airbag 42 is provided with a one-way valve. The drive unit is a commercially available drive motor, referred to as the first motor in this embodiment. A filter screen is disposed inside the air holes 40. The arc-shaped airbag 42 is a polyurethane elastomer. The drive component for driving the connecting frame to slide along the mounting frame 3 is a commercially available drive motor, referred to as the second motor in this embodiment. The working principle of this embodiment is as follows: The fabric is placed on the operating table 1, and the initial position is that the edge pressing roller assembly 4 is above the fabric, and the arc-shaped airbag 42 is in a relaxed state. At this time, the position of the mounting frame 3 is adjusted by sliding along the vertical direction so that the edge pressing roller contacts the fabric. Then, the first motor is driven to make the cam 43 rotate, and the second motor is driven to make the connecting frame slide horizontally along the mounting frame 3. During the rotation of the cam 43, the convex angle periodically squeezes the arc-shaped airbag 42. When the convex angle rotates to contact the arc-shaped airbag 42, the arc-shaped airbag 42 can be squeezed. The gas flows out along the air outlet of the arc-shaped airbag 42, and is sprayed onto the fabric on the operating table 1 through the pipe and air hole 40. When the convex angle of the cam 43 rotates past the arc-shaped airbag 42, the one-way valve is in the open state, and the arc-shaped airbag 42 recovers under its own elasticity and simultaneously sucks in the gas, thereby realizing the continuous spraying and sucking of air. The airflow impact flattens the fabric in advance, and then the hollow roller body 41 presses the edge of the fabric.

[0014] Example 2: Unlike Example 1, as follows Figures 3-4As shown, the side plate 2 has a guide rail for sliding the mounting bracket 3; the drive unit includes a rack 22 horizontally arranged on the mounting bracket 3, a gear 23 rotatably arranged on the connecting frame and meshing with the rack 22, and a transmission belt 21 for belt drive connection between the gear 23 and the cam 43; in this embodiment, the shaft of the gear 23 is rotatably connected to the gear 23, and the mounting bracket 3 is also provided with an electric push rod for pushing the shaft of the gear 53 to move horizontally; It should be noted that the hollow roller body 41 has two mounting blocks on the left and right sides of the side closest to the gear 23, which are fixedly connected to the connecting frame. The opening between the two mounting blocks is used for the transmission belt of the cam 43 and the gear 23 to pass through, so as to meet the requirement of synchronous rotation of the cam 43 and the gear 23 without affecting the fixation of the hollow roller body 41. The working principle of this embodiment is basically the same as that of embodiment 1. The difference is that the electric push rod is used to push the shaft of gear 23 horizontally, so that gear 23 rotates under the action of electric push rod and rack 22, thereby driving cam 43 connected to gear 23 to rotate, so as to realize the periodic compression of arc-shaped airbag 42. Compared with setting an additional motor to drive cam 43 to rotate, it can reduce costs.

[0015] Example 3: Unlike Example 2, as follows Figure 5 As shown, there are 5 arc-shaped airbags 42, and the air holes 40 are all connected to the air outlet of each arc-shaped airbag 42 through pipes. The working principle of this embodiment is basically the same as that of embodiment 2. The difference is that, under the above structure, the number of times the arc-shaped airbag 42 is triggered increases as the cam 43 rotates, thereby improving the jetting efficiency of the air hole 40 and improving the ability to flatten the fabric.

[0016] Example 4: Unlike Example 1, as follows Figure 6 As shown, the four corners of the operating table 1 are equipped with bent limiting members 11, and the bottom of the bent limiting members 11 has a buffer pad; the structure of the bent limiting members 11 is as follows: Figure 6 As shown, it consists of three mounting blocks arranged at 90° angles to each other. The working principle of this embodiment is basically the same as that of embodiment 1. The difference is that after one edge pressing is completed, the rotating bending limiting member 11 is used to fix the unfolded fabric, which makes it easier to press the edges of multiple layers of fabric in sequence on top. The bottom cushioning pad can reduce the wear and tear on the thin fabric.
