Abstract

The utility model discloses a knitted fabric rolling self-adaptive bundling machine, and belongs to the technical field of knitted fabric processing. By arranging the adjusting mechanism and the winding roller set, when the tensioning degree becomes too large, the fabric can pull a pressing roller in the adjusting mechanism to move downwards, a roller shaft frame drives a spring to compress the spring, and therefore the tensioning degree of the fabric is reduced, and the situation that the fabric structure is affected due to the fact that the fabric is wound too tightly in the winding process is avoided; when the pressing roller moves downwards too much, the touch switch can make contact with the lifting plate to be closed, the rotating speed of the swing shaft is reduced by controlling the rotating speed of the driving motor, and therefore self-adaptive adjustment of the tensioning degree in the fabric rolling process is achieved.

Description

Technical Field

[0001] This utility model belongs to the field of knitted fabric processing technology, specifically relating to an adaptive bundling machine for knitted fabric winding. Background Technology

[0002] A bundling machine is a device used to automatically bundle and wind up fabrics or textiles. It is commonly used on fabric production lines to bundle, fold, and wind up fabrics or textiles during the production process for subsequent packaging, storage, and transportation.

[0003] Knitted fabrics are fed into the working area of ​​the bundling machine through a supply system. The fabrics are collected one by one and arranged in a specific direction through a conveyor belt or roll. They are usually bundled and wound up according to their width.

[0004] In order to maintain the appropriate tension of knitted fabrics, tension rollers of different thicknesses are usually selected according to the fabric during the actual production process to tension the fabric. When it is necessary to increase the tension of the fabric, a tension roller with a larger diameter is directly replaced to achieve the purpose of increasing the tension.

[0005] However, this method is very inconvenient in actual use. On the one hand, it requires disassembling and assembling tension rollers of different thicknesses to ensure tension, and on the other hand, it also means that multiple tension rollers of different thicknesses need to be stored. Summary of the Invention

[0006] The present invention aims to solve the technical problems existing in the prior art and provide an adaptive bundling machine for knitted fabric winding.

[0007] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a knitted fabric winding adaptive bundling machine includes two side plates, and an installation plate is provided at the bottom of the inner side of the two side plates. Each installation plate is provided with a telescopic electric cylinder. An adjustment mechanism and a winding roller group are provided between the two side plates. The adjustment mechanism is located above the installation plate. The adjustment mechanism includes a lifting plate. The two ends of the lifting plate are fixedly connected to the extended ends of the two telescopic electric cylinders. A roller frame is provided above the lifting plate. A pressure roller is rotatably connected in the roller frame. Multiple guide rods are on the lower side of the roller frame. The roller frame is slidably connected to the lifting plate through the multiple guide rods. A spring is sleeved on each guide rod between the lifting plate and the roller frame. Multiple touch switches are provided on the lower surface of the roller frame. A contact plate is provided on the lower surface of the lifting plate at the position corresponding to the touch switches.

[0008] Preferably, a drive motor is provided on the front side of the right-side side plate, and a fixed shaft is connected to the drive shaft of the drive motor.

[0009] Preferably, a swing shaft is hinged to the left end of the fixed shaft.

[0010] Preferably, a U-shaped groove for connecting the left end of the swing shaft is provided on the left side plate.

[0011] The beneficial effects of this utility model are as follows: By providing an adjustment mechanism and a winding roller assembly, when the tension becomes too high, the fabric will pull the pressure roller in the adjustment mechanism downward, and the roller frame will drive the spring to compress the spring, thereby reducing the tension of the fabric and preventing the fabric from being wound too tightly during the winding process, which would affect the fabric structure; when the pressure roller moves downward too much, the touch switch will contact the lifting plate and close, thereby controlling the rotation speed of the drive motor to slow down the rotation speed of the swing shaft, thus achieving adaptive adjustment of the tension during the fabric winding process.

[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0015] Example: An adaptive bundling machine for knitted fabric winding, such as Figure 1 As shown, the device includes two side plates 1. A mounting plate 2 is located at the bottom inner side of each side plate 1. Each mounting plate 2 is equipped with a telescopic electric cylinder 3. An adjustment mechanism and a winding roller assembly are located between the two side plates 1. The adjustment mechanism is located above the mounting plate 2 and includes a lifting plate 4. Both ends of the lifting plate 4 are fixedly connected to the extended ends of the two telescopic electric cylinders 3. A roller frame 5 is located above the lifting plate 4. A pressure roller 6 is rotatably connected to the roller frame 5. Multiple guide rods 7 are located on the lower side of the roller frame 5. The roller frame 5 is slidably connected to the lifting plate 4 via the multiple guide rods 7. A spring 8 is fitted on each guide rod 7 between the lifting plate 4 and the roller frame 5. Multiple pressure switches 9 are located on the lower surface of the roller frame 5. A contact plate 10 is located on the lower surface of the lifting plate 4 at a position corresponding to the pressure switches 9.

[0016] A drive motor 11 is provided on the front side of the right side plate 1, and a fixed shaft 12 is connected to the drive shaft of the drive motor 11; a swing shaft 13 is hinged to the left end of the fixed shaft 12; a U-shaped groove 14 for connecting the left end of the swing shaft 13 is provided on the left side plate 1.

[0017] The principle of this invention is as follows: The touch switch 9 is connected to the drive motor 11. The fabric passes through the top of the pressure roller 6 and is finally wound around the swing shaft 13. The drive motor 11 drives the swing shaft 13 to rotate, thereby achieving the winding of the fabric. During the winding process, when the tension of the fabric increases, it pulls the pressure roller 6 downward, thereby driving the lifting plate 4 downward. At the same time, the spring 8 is compressed. When the tension of the fabric decreases, under the elastic force of the spring 8, the pressure roller 6 will move vertically upward away from the lifting plate 4, thereby achieving adaptive adjustment of the fabric tension. When the tension becomes too high, the fabric will pull the pressure roller 6 downward a large distance, causing the touch switch 9 to press against the surface of the lifting plate 4. The touch switch 9 transmits a signal to the drive motor 11, which starts the drive motor 11 to slow down the rotation speed of the swing shaft 13, thereby achieving adaptive adjustment of the tension during the winding of the fabric.

[0018] When it is necessary to remove the rolled-up fabric, the end can be taken out of the U-shaped groove 14 by rotating the hinged swing shaft 13, and the rolled-up fabric can be removed from the swing shaft 13.

[0019] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
