Description

TECHNICAL FIELD

[0001] The utility model relates to textile equipment technical field especially relates to cloth pressing device of cloth rolling machine. BACKGROUND

[0002] In the textile operation process, after the knitting machine weaves cloth, the cloth must be pulled to a cloth rolling machine, and the cloth is rolled on a winding roller by the cloth rolling machine. After the cloth rolling is completed, the winding roller is taken out by cutting and transported to the storage area.

[0003] Chinese invention patent (application number: 2021227596273) discloses that the cloth passes between two assisting rollers, bypasses at least one transition roller, and is wound from the bottom of the last transition roller to the first rolling roller, and then is pressed by the winding roller. With the rotation of the winding roller driven by the first rolling roller and the second rolling roller, the cloth is covered on the outer edge of the winding roller. During the winding process, the transition roller cooperates to guide the cloth to the winding process while also being used to unfold and flatten the cloth, thereby preventing wrinkles in the cloth during the winding process and avoiding disordered situations due to wrinkles. However, if the cloth output speed at the front end is greater than the cloth winding speed at the rear end, the excess cloth may accumulate between the transition rollers, and at this time, the cloth between the assisting rollers and the winding roller is not in a straightened state. If the winding roller continues to wind the cloth, wrinkles will appear in the cloth at this stage, and in severe cases, the cloth on the winding roller will tilt, which not only affects the accuracy of subsequent cutting, but also may cause waste of raw materials.

[0004] Therefore, the present inventors have conducted in-depth research on the above problems, and thus the present application is produced. CONTENT OF THE UTILITY MODEL

[0025] The fabric pressing device of the fabric rolling machine includes a fabric pressing mechanism 3 mounted on the base of the fabric rolling machine and used to press the fabric on the rolling roller 1 to different degrees to flatten the fabric on the take-up roller 2. The fabric pressing mechanism 3 is located in front of the rolling roller 1. It is worth noting that the fabric rolling machine in this embodiment adopts Chinese invention patent (application number: 2021227596273). This embodiment is based on the fabric rolling machine with the fabric pressing device configured. Of course, the fabric pressing device of this application is also applicable to other fabric rolling machines.

[0026] The pressing mechanism 3 includes a mounting frame 31 mounted on a base, a slide rail 32 mounted on the mounting frame 31, a slider 33 mounted on the slide rail 32, a drive unit that drives the slider 33 to move back and forth along the length of the slide rail 32, and a pressing member 34 mounted on the mounting frame 31. At least one transmission unit 4 is also provided between the pressing member 34 and the slider 33, which drives the pressing member 34 to move in a second direction by the movement of the slider 33 in a first direction. The pressing member 34 can move movably closer to or further away from the rolling roller 1 in the second direction. Furthermore, there are multiple transmission units 4, evenly distributed along the first direction. To maintain balance, this embodiment provides three transmission units 4. In this case, three sliders 33 can be provided, each corresponding to one of the three transmission units 4. Alternatively, only one slider 33 can be provided. The three transmission units 4 are respectively located at both ends and the middle of the slide rail 32, facilitating the smooth movement of the pressing member 34 towards or away from the take-up roller 2.

[0027] Furthermore, the driving unit is a cylinder 5, the cylinder body of which is mounted on the mounting frame 31. One end of the piston rod of the cylinder 5 is retractably mounted inside the cylinder body, and the other end is connected to the first connecting member 41, so as to drive the first connecting member 41 and the slider 33 to slide along the slide rail 32 through the piston rod. It is worth noting that the driving unit in this embodiment can also be an electric motor, which will not be described in detail here.

[0028] Furthermore, the transmission unit 4 includes a first connector 41 connected to the slider 33 and a second connector 42 connected to the mounting frame 31.

[0029] Furthermore, the first connecting member 41 is provided with a first slide groove 45 for the first pin 43 to slide in. The first slide groove 45 is arranged along a first direction. The first slide groove 45 has a first positioning point 451 for the pressure cloth member 34 to move along a second direction to be close to the rolling roller 1 and a second positioning point 452 for the pressure cloth member 34 to move along a second direction to be away from the rolling roller 1. The distance between the first positioning point 451 and the reference surface 311 is greater than the distance between the second positioning point 452 and the reference surface 311, so that when the slider 33 slides, the first pin 43 drives the pressure cloth member 34 to move in the direction close to or away from the take-up roller 2.

[0030] Furthermore, the second connecting member 42 is provided with a second sliding groove 46 that restricts the movement of the pressing cloth member 34 in the first direction.

The distance between the third positioning point 461 and the reference surface 311 is greater than the distance between the fourth positioning point 462 and the reference surface 311.

[0031] Furthermore, when the pressing component 34 approaches and causes the fabric to press against the rolling roller 1, the first pin 43 is set on the first positioning point 451 and the second pin 44 is set on the third positioning point 461; when the pressing component 34 moves away from the rolling roller 1, the first pin 43 is set on the second positioning point 452 and the second pin 44 is set on the fourth positioning point 462.

[0032] In use, first start the electrical control host of the fabric rolling machine, which is electrically connected to the drive unit, so that the drive unit is in the open mode, and drives the slider 33 to move in the first direction of the slide rail 32. This causes the first pin 43 to drive the pressing part 34 to move closer to or away from the take-up roller 2. At the same time, the second pin 44 restricts the pressing part 34 from moving in the first direction. That is, the pressing part 34 moves closer to or away from the take-up roller 2 in the second direction, and the fabric wrapped on the second take-up roller 2 is pressed with appropriate tightness.

[0033] By adopting the aforementioned design scheme, the beneficial effects of this utility model are as follows: A transmission unit 4 is provided between the pressing component 34 and the slider 33, which drives the pressing component 34 to move in the second direction via the movement of the slider 33 in the first direction. This allows the pressing component 34 to move movably closer to the rolling roller 1 in the second direction, preventing wrinkles in the fabric during winding and avoiding misalignment due to wrinkles. Simultaneously, when winding fabrics of different thicknesses, this utility model can adjust the transmission unit 4 to change the distance between the pressing component 34 and the rolling roller 1, allowing the winding roller 2 to press fabrics of different thicknesses, thus having a wide range of applications. Furthermore, this utility model uses bolts to install the mounting frame 31 onto the base, making installation and disassembly convenient and easy to use.
