Description

Technical Field

[0001] This utility model relates to the field of textile printing and dyeing technology, specifically to a pre-damage reduction tool for pre-shrinking fabric feeding in a pre-shrinking machine and a pre-shrinking machine. Background Technology

[0002] Pre-shrinking is an essential step in the production of dyed and printed fabrics. It involves shrinking the dyed and finished fabric before washing to prevent deformation and shrinkage. Currently, pre-shrinking machines are commonly used for this process. The core component of the pre-shrinking machine is a rubber blanket. This blanket, in conjunction with a heated drying cylinder on the machine, compresses and shrinks the wet fabric under high temperature and pressure, thereby stabilizing the fabric's dimensions. Given the relatively high cost of rubber blankets, ensuring their consistent quality and preventing surface abrasion, scratches, or punctures from foreign objects is crucial.

[0003] Before pre-shrinking printed and dyed fabrics, a stretching process is required, such as using a pin plate stretching machine. The pin plate secures the fabric edges to ensure smooth fabric movement. During the stretching process, needles inevitably penetrate the fabric. These needles, upon entering the pre-shrinking machine, come into contact with and embed themselves in the rubber blanket, causing damage, reducing its lifespan, and increasing the manufacturing cost of the printed and dyed fabrics.

[0004] Therefore, this patent application is filed. Summary of the Invention

[0005] In view of the above, and to solve the problems existing in the prior art, this utility model provides a pre-damage reduction tooling for pre-shrinking fabric in a pre-shrinking machine, and also provides a pre-shrinking machine, on which the aforementioned pre-damage reduction tooling is installed, for processing the fabric at the front end of the pre-shrinking machine to remove needles from the fabric, so as to avoid damage to the rubber blanket by the needles and reduce manufacturing costs.

[0006] The first objective of this utility model is to provide a pre-damage reduction tooling for pre-shrinking fabric feeding in a pre-shrinking machine, comprising a support frame and a magnetic suction component. The support frame is connected to the main beam frame of the pre-shrinking machine, and the fabric feeding drive roller of the pre-shrinking machine is located below the support frame. The magnetic suction component is installed on the support frame to attract and remove needles from the fabric being fed through the drive.

[0007] As a preferred design, the magnetic element is fixed inside the mounting strip, which is detachably fixed to the side wall of the support frame.

[0008] As a preferred design, it also includes a support column and a reinforcing strip. The support column is fixed to the support frame, and the reinforcing strip is fixedly installed on the side of the support column near the transmission fabric. The reinforcing strip has a reinforcing magnet inside, and the height of the reinforcing strip is higher than the height of the mounting strip.

[0009] As a preferred design, the support column is arranged perpendicular to the support frame so that the fabric can pass between the magnetic chuck and the reinforcing strip.

Detailed Implementation

[0022] The technical solutions of various embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0024] like Figure 1 , 2As shown in Figure 3, a pre-feeding loss reduction fixture for a pre-shrinking machine includes a support frame 1 and a magnetic suction component. The support frame 1 is fixedly installed on the main beam frame 2 of the pre-shrinking machine, and is located at the front end of the main beam frame. It performs needle removal at the front end of the pre-shrinking fabric feeding process. The support frame 1 is made of stainless steel. The fabric feeding drive roller 3 of the pre-shrinking machine is located below the support frame 1. The magnetic suction component is installed on the side of the support frame 1 facing the fabric feeding drive roller 3. The magnetic suction component has strong magnetism and can attract ferromagnetic needles. The magnetic suction component is fixedly installed inside an mounting strip 4, which is detachably fixed to the support frame 1 by screws. The mounting strip 4 can be designed as a hollow shell structure, made of stainless steel, with a smooth surface, which is more conducive to fabric transmission and will not affect the fabric due to surface corrosion.

[0025] During fabric feeding, the fabric first passes through the support frame 1, and then is conveyed by the fabric feeding transmission roller 3 into the subsequent pre-shrinking process. As the fabric passes through the support frame 1, the magnetic attraction on the support frame 1 removes the needle tip, thus reducing wear.

[0026] Furthermore, to improve the needle removal effect, a support column 5, a crossbeam 6, and a reinforcing strip 7 are provided. The support column 5 is fixed to the support frame 1 and is perpendicular to the support frame 1. The two ends of the crossbeam 6 are fixedly connected to the support column 5. The reinforcing strip 7 is fixedly installed on the side of the crossbeam 6 near the transmission fabric. A reinforcing magnet is provided inside the reinforcing strip 7, and the height of the reinforcing strip 7 is higher than the height of the mounting strip 4. The reinforcing strip 7 is also made of stainless steel.

[0027] In this embodiment, by setting the support column 5 and the reinforcing strip 7, a structure is formed in which the mounting strip 4 and the reinforcing strip 7 are staggered and opposite each other, and an angular clearance space is formed between the mounting strip 4 and the reinforcing strip 7. The mounting strip 4 and the reinforcing strip 7 are located on both sides of the fabric, allowing the fabric to pass through the clearance space. The needles on the fabric are first removed by the reinforcing strip 7 on one side, and then by the mounting strip 4 on the other side. This two-stage removal enhances the needle removal effect and improves the protection of the rubber blanket. Example

[0028] like Figure 1 , 2 As shown in Figure 3, based on Embodiment 1, to further enhance the needle removal effect, the support column 5 and the support frame 1 are designed to be slidably fitted. Adjusting the position of the support column 5 causes a change in the distance between the reinforcing strip 7 and the mounting strip 4, altering the spacing with the fabric to accommodate needle removal from fabrics at different conveying angles.

[0029] The sliding fit structure is as follows: the support frame 1 is provided with a first slide rail 8, the end of the support column 5 mates with the circumferential surface of the first slide rail 8, and can slide along the surface of the first slide rail 8. A through hole is also provided on the support column 5 for inserting a fastening screw 9. Tightening the fastening screw 9 causes it to abut against the surface of the first slide rail 8, thus locking the support column 5 and stopping its movement. Loosening the fastening screw 9 allows the support column 5 to move, thereby adjusting the gap between the reinforcing strip 7 and the fabric. Example

[0030] Based on Embodiment 1 or Embodiment 2, a needle collection mechanism is further provided below the main beam frame 2. The needle collection mechanism includes a second slide rail 10, a sliding bar 11, and a collection hopper 12. The second slide rail 10 is fixedly installed on the bottom surface of the main beam frame 2. The sliding bar 11 is located below the second slide rail 10, with one end of the sliding bar 11 slidingly engaged with the second slide rail 10, and the other end of the sliding bar 11 connected to the collection hopper 12, with the two rotatably engaged. The end of the sliding bar 11 away from the second slide rail 10 can be designed as an L-shape. A rotating shaft is fixedly provided at both ends of the collection hopper 12, and both rotating shafts are inserted into the L-shaped end of the sliding bar 11, with the rotating shafts and sliding bar 11 rotatably engaged. The collection hopper 12 is located to the side of the sliding bar 11.

[0031] During the production process, when needles need to be collected, the sliding bar 11 can be moved so that the collecting hopper 12 is directly below the mounting bar 4 and the reinforcing bar 7, respectively. After collection is complete, rotating the collecting hopper 12 will cause the needles to fall out. Then, the sliding bar 11 can be removed. In this embodiment, the needle collecting mechanism facilitates the operation of needle collection. Example

[0032] like Figure 4 As shown, a pre-shrinking machine includes a pre-damage reduction fixture as described in Embodiment 1, 2, or 3, and a pre-set drive roller 13. The pre-set drive roller 13 is mounted on the main beam frame 2 of the pre-shrinking machine and rotatably engages with the main beam frame 2. The pre-set drive roller 13 is arranged side by side with the fabric feeding drive roller 3, and is located below the support frame 1 and at the front end of the feed drive roller. The purpose of setting the pre-set drive roller 13 is to facilitate the adjustment of the inclination angle of the fabric feed, adjust the spacing between the feed and mounting strips 4 and the reinforcing strips 7, and also to pre-adjust the fabric tension.

[0033] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the present invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the present invention, and these should also be considered within the scope of protection of the present invention.
