Abstract
Description
Technical Field
[0001] This utility model relates to a fabric spreading machine, and more specifically, to an automatic fabric spreading machine with anti-air bulge. Background Technology
[0002] A fabric spreading machine is a machine that spreads fabric, replacing manual labor. It straightens folded, rolled, or coiled fabric to a certain length and lays it out layer by layer on a cutting bed, facilitating subsequent cutting processes. This is the working mechanism of such a machine. With the development of industrialization, the garment industry has gradually shifted from traditional labor-intensive to industrialized and automated production. Fabric spreading machines entered the domestic market in the early 1990s and became a new choice for many garment companies. Due to the flexible nature of the materials, most of them are produced and transported in rolls. Therefore, an important process at the user's factory is to transform the roll of material into a multi-layered flat state for easy cutting. Automated production equipment such as automatic fabric spreading machines and automatic fabric laying machines have emerged to meet this need.
[0003] When the fabric spreading machine operates at too high a speed or stretches the fabric unevenly, air cannot escape smoothly from the fabric during the rapid stretching and spreading process, leading to air bulging. This results in the cut fabric having a slanted cut after straightening, affecting production quality. Furthermore, when air bulging occurs, the machine needs to be stopped and its operating parameters adjusted, impacting production efficiency. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a simple, air-drum-proof automatic fabric pulling machine that can scrape out air from inside the fabric.
[0005] The technical solution of this utility model is implemented as follows: An automatic fabric spreading machine with anti-air bulge includes a machine base. At one end of the machine base, there is a feeding and cutting component for placing fabric rolls. The machine base is provided with a fabric spreading panel for placing fabric and having a plurality of exhaust holes evenly distributed on its surface. Above the fabric spreading panel, there is a clamping and spreading component that moves along the length direction. Between the clamping and spreading component and the feeding and cutting component, there is a translation component that moves along the length direction. A lifting component is provided on the translation component. The lifting component is provided with an air-de-gas scraper made of rubber material. The machine base below the fabric spreading panel is provided with a dust extraction groove connected to an external negative pressure air source.
[0006] In the aforementioned automatic fabric pulling machine for preventing air bulges, the fabric pulling assembly includes horizontal guide rails arranged on both sides of the fabric pulling panel, a first sliding seat on each horizontal guide rail, a first mounting beam between two first sliding seats, and a plurality of pneumatic grippers evenly distributed along the length direction on the first mounting beam; a first linear drive unit is connected to one of the first sliding seats.
[0007] In the aforementioned automatic fabric spreading machine for preventing air bulges, the first linear drive unit includes a transmission belt unit mounted on the machine base, the transmission belt unit being connected to a servo motor; a connecting rod is provided on the outside of the first sliding seat, the lower end of the connecting rod being connected to the belt of the transmission belt unit.
[0008] In the aforementioned anti-air-bulge automatic fabric spreading machine, a vertical mounting column is provided at one end of the first sliding seat near the material feeding and cutting component, and the first mounting beam is arranged between the vertical mounting columns on both sides. A reinforcing rib is provided between the side of the vertical mounting column away from the material feeding and cutting component and the first sliding seat.
[0009] In the aforementioned automatic fabric pulling machine for preventing air bulges, the translation component includes a second sliding seat disposed on a horizontal guide rail, a second mounting beam is provided between the two second sliding seats, and the lifting component is disposed on the second mounting beam; a second linear drive unit is connected to the second sliding seat on the side opposite to the first linear drive unit.
[0010] In the aforementioned automatic fabric spreading machine for preventing air ducts, the bottom end of the degassing scraper is provided with a scraping rod.
[0011] In the aforementioned automatic fabric spreading machine for preventing air bulges, the bottom end of the degassing scraper is provided with a T-shaped connecting part, and the scraping rod is provided with an installation slot that mates with the T-shaped connecting part.
[0012] In the aforementioned automatic fabric spreading machine for preventing air bulges, the machine base is provided with an installation groove, and a support mesh frame is provided in the installation groove. The fabric spreading panel is detachably installed in the installation groove.
[0013] In the aforementioned automatic fabric pulling machine for preventing air bulges, the lifting assembly is provided with a mounting plate, and a mounting seat is provided below the mounting plate. The mounting seat is movably mounted on the mounting plate via two guide rods. The degassing scraper is located at the bottom of the mounting seat, and a tension spring is provided on the guide rod between the mounting seat and the mounting plate.
[0014] With the above-mentioned structure, after the fabric is flattened by the clamping and pulling assembly, the fabric is scraped and smoothed by the reciprocating motion of the de-gassing scraper. The internal air is discharged through the exhaust hole on the fabric pulling panel, and the fabric at the air bulge is smoothed, ensuring the quality of fabric cutting and improving production efficiency.
[0015] Meanwhile, the dust extraction groove located at the bottom of the fabric panel can not only suck up the dust and debris scraped off the fabric, but also absorb the fabric and remove the air from the bottom of the fabric, further preventing air bubbles from forming.

[0024] See Figure 1-6 As shown, this utility model discloses an automatic fabric spreading machine with anti-air bulge, comprising a machine base 1, a feeding and cutting assembly 2 for placing fabric rolls at one end of the machine base 1, a fabric spreading panel 3 for placing fabric and having several evenly distributed exhaust holes on its surface, a clamping and spreading assembly 4 that moves along the length direction above the fabric spreading panel 3, and a translational assembly 5 that moves along the length direction between the clamping and spreading assembly 4 and the feeding and cutting assembly 2; a lifting assembly 6 on the translational assembly 5, and a degassing scraper 7 made of rubber material on the lifting assembly 6; and a dust extraction groove 8 connected to an external negative pressure air source on the machine base 1 below the fabric spreading panel 3. In the initial state, the degassing scraper is raised above the clamping and spreading assembly by the lifting assembly, providing sufficient space for the clamping and spreading assembly to clamp the end of the fabric on the feeding and cutting assembly.
[0025] After the fabric is pulled flat by the clamping and spreading assembly, the fabric is scraped and smoothed by the reciprocating motion of the de-airing scraper. The internal air is discharged through the exhaust holes on the fabric spreading panel, and the fabric at the air drum is smoothed, ensuring the quality of fabric cutting and improving production efficiency.
[0026] Meanwhile, the dust extraction groove located at the bottom of the fabric panel can not only suck up the dust and debris scraped off the fabric, but also absorb the fabric and remove the air from the bottom of the fabric, further preventing air bubbles from forming.
[0027] During the fabric spreading process, the fabric will continuously stack and rise. The rubber-made degassing scraper can adapt to the deformation of fabric at different stacking heights, eliminating the need for precise control of the height of the lifting components and reducing equipment costs.
[0028] In this embodiment, the fabric gripping and spreading assembly 4 includes horizontal guide rails 9 mounted on the machine base 1 on both sides of the fabric spreading panel 3. Each horizontal guide rail 9 has a first sliding seat 4a, and a first mounting beam 4b is provided between two first sliding seats 4a. Several pneumatic grippers 4c are evenly distributed along the length of the first mounting beam 4b. A first linear drive unit 10 is connected to one of the first sliding seats 4a. The position of the pneumatic grippers is adapted to the position of the front end of the fabric on the fabric gripping and spreading assembly. A corresponding mounting bracket is provided on the first mounting beam to ensure that the front end of the pneumatic grippers has sufficient length to reach the fabric gripping and spreading assembly from below the degassing scraper.
[0029] In this embodiment, preferably, the first linear drive unit 10 includes a transmission belt unit 10a mounted on the machine base 1, the transmission belt unit 10a being connected to a servo motor; a connecting rod 10b is provided on the outer side of the first sliding seat 4a, the lower end of the connecting rod 10b being connected to the belt of the transmission belt unit 10a. The servo motor controls the reciprocating motion of the belt to drive the first sliding seat to move; this is a common drive structure in the art, and its specific connection method is common knowledge to those skilled in the art, and will not be described in detail here.
[0030] In this embodiment, the transmission belt unit is located at the bottom of the machine base, and a clearance elongated hole is provided on the surface of the machine base to cooperate with the connecting rod. The connecting rod passes through the clearance elongated hole and is connected and fixed to the belt below. The clearance elongated hole can limit the connecting rod and reduce the possibility of the connecting rod swinging and tilting during movement, which may cause it to jam.
[0031] More preferably, the first sliding seat 4a has a vertical mounting post 4d at one end near the feeding and cutting assembly 2, and the first mounting beam 4b is disposed between the two vertical mounting posts 4d. A reinforcing rib 4e is provided between the vertical mounting post 4d and the first sliding seat 4a on the side away from the feeding and cutting assembly 2. This structure improves the stability of the first mounting beam and can extend the length of the first sliding seat, reducing the possibility of the first sliding seat tilting during sliding along the horizontal guide rail.
[0032] In this embodiment, preferably, the translation component 5 includes a second sliding seat 5a disposed on the horizontal guide rail 9, a second mounting beam 5b disposed between the two second sliding seats 5a, and the lifting component 6 disposed on the second mounting beam 5b; a second linear drive unit 5c is connected to the second sliding seat 5a on the side opposite to the first linear drive unit 10. The second linear drive unit adopts the same structure as the first linear drive unit and is disposed on the side opposite to the first linear drive unit to avoid interference with the first linear drive unit. The second sliding seat has the same structure as the first sliding seat, and the overall stability is increased by extending the length of the first sliding seat and adding reinforcing ribs.
[0033] In this embodiment, preferably, the bottom end of the degassing scraper 7 is provided with a scraping rod 11. By providing the scraping rod, the pressure of the degassing scraper on the fabric surface is increased, ensuring that the air contained in the fabric can be completely scraped out.
[0034] More preferably, the bottom end of the degassing scraper 7 is provided with a T-shaped connecting part 12, and the scraper rod 11 is provided with a mounting slot 13 that mates with the T-shaped connecting part 12. This structure facilitates the replacement of the scraper rod, allowing for the selection of scraper rods of different weights according to the softness or hardness of the fabric to ensure complete pressing of any bulging fabric. A rounded end is provided at the T-shaped connecting part to facilitate mating with the mounting slot.
[0035] In this embodiment, the machine base 1 is provided with a mounting groove 14, and a support frame 15 is provided within the mounting groove 14. The fabric panel 3 is detachably mounted within the mounting groove 14. In this embodiment, the side walls of the mounting groove are formed by horizontal guide rails on both sides. This structure facilitates quick installation of the fabric panel, allows for rapid replacement of the fabric panel if it deforms after prolonged use, and reduces the possibility of deformation caused by scraping or pressing by supporting the fabric panel through the support frame.
[0036] In this embodiment, the lifting assembly 6 is provided with a mounting plate 16, and a mounting base 17 is provided below the mounting plate 16. The mounting base 17 is movably mounted on the mounting plate 16 via two guide rods 18. The degassing scraper 7 is located at the bottom end of the mounting base 17, and a tension spring 19 is provided on the guide rods 18 between the mounting base 17 and the mounting plate 16. The tension spring increases the adaptive deformation capability of the degassing scraper, which can better accommodate fabrics with different stacking heights, and at the same time, it can increase the pressing force of the degassing scraper on the fabric, thereby improving the ability to squeeze out air from the fabric.
[0037] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
