Description

Technical Field

[0001] This utility model relates to the field of pretreatment technology for polyester fabrics, and in particular to a pretreatment device for wrinkle-resistant polyester fabrics. Background Technology

[0002] In the production of polyester fabrics, in order to improve the wrinkle resistance, appearance quality, and comfort and durability of the polyester fabrics during subsequent use, it is necessary to use a wrinkle-resistant polyester fabric pretreatment equipment. Through pretreatment processes such as high-temperature setting, steam treatment or resin finishing, the wrinkle resistance of the fabric is further enhanced, making the fabric smoother and reducing the need for subsequent care.

[0003] Pretreatment typically removes impurities that may adhere to polyester fabrics during production, such as grease, dust, and dirt, and provides a good foundation for subsequent processing. Pretreatment involves washing and degreasing, bleaching, dyeing, drying, and setting. These processes not only improve the appearance, feel, and performance of polyester fabrics but also endow them with more functions, such as wrinkle resistance, water resistance, and antistatic properties, thereby enhancing their market competitiveness.

[0004] Considering that the fabric tension needs to be adjusted during degreasing, bleaching, dyeing, drying, and setting processes to prevent it from becoming loose and prone to wrinkles or creases, thus affecting subsequent processing results, tension adjustment is usually achieved by disassembling and adjusting the distance of rollers to control the tension of the fabric at different processing steps. This process not only requires complex manual operation for disassembling and readjusting the roller distance, but also often necessitates stopping the machine before manually disassembling and reinstalling the rollers, impacting production efficiency. Therefore, a wrinkle-resistant polyester fabric pretreatment device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pretreatment device for wrinkle-resistant polyester fabric, which aims to improve the existing technology in the degreasing, bleaching, dyeing, drying and setting of fabrics. In order to prevent the fabric from loosening, wrinkling or folding, tension is usually controlled by disassembling and adjusting the distance of the rollers. However, this adjustment method not only requires complicated manual operation, but also requires stopping the machine for disassembly and reinstallation, which seriously affects the production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pretreatment device for wrinkle-resistant polyester fabric, comprising a treatment box, a frame fixedly connected to the outer surface of the treatment box, a groove A opened on the inner surface of the frame, a movable shell slidably connected to the inner surface of the groove A, a lead screw rotatably connected through and to the top of the inner surface of the movable shell, an adjusting roller threadedly connected to the outer surface of the lead screw, a bevel gear B fixedly connected to the bottom of the outer surface of the lead screw, the outer surface of the bevel gear B rotatably connected to the inner surface of the movable shell, a bevel gear A meshing with the bottom of the outer surface of the bevel gear B, the outer surface of the bevel gear A rotatably connected to the front end of the inner surface of the movable shell, a column rotatably connected through and fixedly connected to the inner surface of the bevel gear A, and a guide assembly provided on the inner surface of the treatment box.

The outer surface of the fabric is in contact with the outer surfaces of the three sets of rollers. The middle of the outer surface of the fabric is in contact with the bottom of the outer surface of the adjusting roller.

[0009] As a further description of the above technical solution:

[0010] A handle is hinged to the right side of the outer surface of the movable shell, and a snap-fit ​​plate is fixedly connected to the right side of the outer surface of the frame. The outer surface of the handle snaps into the right side of the inner surface of the snap-fit ​​plate, and the snap-fit ​​plate is provided in multiple sets.

[0011] As a further description of the above technical solution:

[0012] The outer surface of the processing box is provided with a guide groove, and the outer surface of the adjusting roller is slidably connected to the inner surface of the guide groove.

[0013] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by providing a lead screw and two sets of bevel gears, when adjusting the adjusting roller, it is only necessary to rotate the turntable to control the rotation of the bevel gears, so that the bevel gears drive the lead screw to rotate, allowing the lead screw to slowly control the height of the adjusting roller, thereby achieving stable and delicate tension control of the fabric. This simplifies the operation, avoids the complexity of traditional manual disassembly and adjustment, improves production efficiency, and eliminates the need to stop the machine.

[0023] 2. In this utility model, by providing a movable shell, a handle, and a locking plate, when it is necessary to quickly release the tension control of the adjusting roller on the fabric, the handle and the locking plate are first released, and then the movable shell is pulled upward, which causes the lead screw and the adjusting roller to move upward simultaneously, thereby releasing the pressure of the adjusting roller on the fabric. This allows for a rapid response to changes in production needs, increasing the flexibility and adjustability of the production line and adapting to different process requirements.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a pretreatment device for wrinkle-resistant polyester fabric, including a treatment box 1. A frame 4 is fixedly connected to the outer surface of the treatment box 1, providing fixed support for the frame 4. A sliding groove A14 is formed on the inner surface of the frame 4, allowing a movable shell 9 to move vertically along the inner surface of the frame 4. The movable shell 9 is slidably connected to the inner surface of the sliding groove A14, ensuring that the movable shell 9 always moves to a designated position when moving vertically along the inner surface of the frame 4. A lead screw 7 is rotatably connected through and to the top of the inner surface of the movable shell 9, allowing the bottom of the outer surface of the lead screw 7 to rotate along the top of the inner surface of the movable shell 9. An adjusting roller 10 is threadedly connected to the outer surface of the lead screw 7, enabling the lead screw 7 to drive the adjusting roller 10 to move vertically when rotating. A bevel gear B13 is fixedly connected to the bottom of the outer surface of the lead screw 7. The bevel gear B13, when rotating, drives the lead screw 7 to rotate. The outer surface of the bevel gear B13 is rotatably connected to the inner surface of the movable housing 9, allowing the bevel gear B13 to rotate along the inner surface of the movable housing 9. The bottom end of the outer surface of the bevel gear B13 is meshed with the bevel gear A12, so that when the bevel gear A12 rotates, it can convert vertical rotation into horizontal rotation due to meshing with the bevel gear B13, thus driving the lead screw 7 to rotate together. The outer surface of the bevel gear A12 is rotatably connected to the front end of the inner surface of the movable housing 9, allowing the bevel gear A12 to rotate along the front end of the inner surface of the movable housing 9. The inner surface of the bevel gear A12 is penetrated and fixedly connected to the column 15, so that when the column 15 rotates, it can drive the bevel gear A12 to rotate together. The inner surface of the processing box 1 is provided with a guide assembly, allowing the fabric 2 to move along a designated position through the guide assembly.

[0033] Reference Figure 1 , Figure 4 - Figure 5The guiding assembly includes fabric 2 and rollers 3. Rollers 3 are arranged in three sets. One set of rollers 3 is rotatably connected to the top of the inner surface on the right side of the processing box 1, allowing it to pull the fabric 2 outside the processing box 1 into the processing box 1. Two sets of rollers 3 are rotatably connected to the middle of the inner surface on the left side of the processing box 1, allowing them to smoothly output the fabric 2, after its tension has been adjusted by the adjusting roller 10, along a designated position. The outer surface of the fabric 2 contacts the outer surfaces of the three sets of rollers 3, allowing it to move along a designated position under the traction of the rollers 3. The middle of the outer surface of the fabric 2 contacts the bottom end of the outer surface of the adjusting roller 10, allowing the adjusting roller 10 to move at an angle... When moving, the tension of the fabric 2 can be adjusted. A handle 11 is hinged to the right side of the outer surface of the movable shell 9, allowing the handle 11 to be flipped along the right side of the outer surface of the movable shell 9. When the handle 11 is operated, the movable shell 9 can be moved vertically. A snap-fit ​​plate 8 is fixedly connected to the right side of the outer surface of the frame 4, providing a fixed support for the snap-fit ​​plate 8. The outer surface of the handle 11 snaps into the right side of the inner surface of the snap-fit ​​plate 8, allowing the movable shell 9 to be fixed in a designated position when the handle 11 snaps into the right side of the inner surface of the snap-fit ​​plate 8. Multiple sets of snap-fit ​​plates 8 are provided, allowing the handle 11 to fix the movable shell 9 in more positions.

[0034] Reference Figure 1 - Figure 2 , Figure 5 The outer surface of the processing box 1 is provided with a guide groove 16, which allows the adjusting roller 10 to move vertically along the inner surface of the processing box 1. The outer surface of the adjusting roller 10 penetrates and slides through the inner surface of the guide groove 16, so that the adjusting roller 10 can always maintain vertical movement along a specified position. The guide groove 16 is inclined, so that when the adjusting roller 10 moves vertically, it can be inclined due to the guide groove 16, allowing the adjusting roller 10 to move obliquely upward or downward. This allows the adjusting roller 10 to better adapt to the tilt angle of the fabric 2 when adjusting the tension, preventing damage to the fabric 2 during tension adjustment. The outer surface of the column 15... A turntable 5 is fixedly connected to the end, so that when the turntable 5 rotates, it can drive the column 15 to rotate together. A sleeve 6 is rotatably connected to the front end of the outer surface of the turntable 5, so that the sleeve 6 can rotate the front end of the outer surface of the turntable 5. The sleeve 6 rotates around the center of the turntable 5, so that when rotating the turntable 5, the sleeve 6 is held and the circular motion is performed, so that the turntable 5 can be rotated more effortlessly. The top of the outer surface of the lead screw 7 is slidably connected to the top of the inner surface of the frame 4, so that when the moving shell 9 drives the lead screw 7 to move vertically along the frame 4, the lead screw 7 will not be blocked by the top of the inner surface of the frame 4, thus preventing the moving shell 9 from moving.

[0035] Reference Figure 1 , Figure 4 The outer surface of the frame 4 has a sliding groove B17 at the front end, which allows the column 15 to move vertically along the inner surface of the frame 4. The outer surface of the column 15 is rotatably and slidably connected to the inner surface of the sliding groove B17, which allows the column 15 to always move along the specified position when moving vertically. The outer surface of the column 15 is rotatably and slidably connected to the inner surface of the guide groove 16, which allows the column 15 to also move along the inner surface of the processing box 1 when moving.

[0036] Working principle: When using the device, fabric 2 first enters the processing box 1 from the right side and contacts the top of the outer surface of a set of rollers 3 on the right side of the processing box 1. Then, the top of fabric 2 passes through the bottom of the outer surface of the adjusting roller 10 and then passes between the two sets of rollers 3 on the left side of the processing box 1, so that fabric 2 forms a V-shape inside the processing box 1. When adjusting the tension of fabric 2, after holding the sleeve 6, perform an arc motion, which drives the turntable 5 to pull the column 15 to rotate. When the column 15 rotates, it simultaneously pulls the two sets of rollers 3. The bevel gear A12 rotates, causing it to drive two sets of bevel gears B13 to rotate. These bevel gears B13 then drive two sets of lead screws 7 to rotate. Since the outer surfaces of the two sets of lead screws 7 are threaded to the inner surfaces of the adjusting roller 10, the lead screws 7 cause the adjusting roller 10 to move downwards, pressing down on the middle of the fabric 2. This increases the tension of the fabric 2. To reduce the tension, simply reverse the turntable 5, causing it to reverse the lead screws 7 and move the adjusting roller 10 upwards, reducing the pressure on the fabric 2 and thus reducing the fabric tension.

[0037] When it is necessary to quickly release the tension control of the adjusting roller 10 on the fabric 2, first straighten the handle 11 to release the engagement between the handle 11 and the bottom locking plate 8 of the frame 4. Then, operate the handle 11 to move the moving shell 9 upward, so that it moves the lead screw 7 and the adjusting roller 10 upward together. When it reaches the designated position, bend the handle 11 so that the handle 11 engages with the locking plate 8 at the top of the frame 4, thereby quickly releasing the tension control of the adjusting roller 10 on the fabric 2.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
