Description

Technical Field

[0001] This invention belongs to the field of textile equipment technology, specifically a fabric printing and pressing mechanism. Background Technology

[0002] A fabric printing flattening mechanism is a finishing device used after the textile printing process to eliminate wrinkles and fix patterns. Its core structure usually consists of a heated roller, an elastic pressure roller, and a tension adjustment device. It uses high temperature and high pressure to flatten the printed fabric evenly and quickly set the shape. Its main functions are to improve the clarity of the pattern, prevent ink bleeding, and improve the smoothness of the fabric. Common forms include roller-type hot flattening machines, belt-type continuous hot press machines, and vacuum suction flattening machines. They are widely used in the finishing stages of digital printing, rotary screen printing, and transfer printing production lines.

[0003] For example, CN218756660U discloses a fabric printing and flattening mechanism, including a base frame, a transmission mechanism at the top of the base frame, a housing bolted to the top of the base frame, a cleaning mechanism inside the housing, and a suction fan bolted to the inner wall of the housing. This invention cleans the fabric surface using the cleaning mechanism to remove lint, and the suction fan draws the lint into a connecting pipe, which then enters the housing and is filtered through a filter screen. This method effectively removes lint, ensuring environmental cleanliness and protecting human health. Furthermore, by moving a locking rod to disengage it from the locking hole on a fixed rod, and by moving the fixed rod, this invention can flatten fabrics of different thicknesses, reducing production costs, improving the practicality of the device, and making it convenient to use.

[0004] However, in actual use, it was discovered that different fabrics require different printing methods. Some printing methods require rolling to press the fabric, while for other fabrics that are very thin, rolling can cause wrinkles. Conventional printing machines can only handle one type of printing, but this increases the overall cost. Therefore, to solve this problem, a comprehensive printing machine was designed to adapt to these variations. Summary of the Invention

[0005] The purpose of this invention is to provide a fabric printing and flattening mechanism in order to solve the problems mentioned above.

[0006] The technical solution adopted in this invention is as follows: a fabric printing and flattening mechanism, wherein the transmission boxes are symmetrically distributed on both sides of the conveyor belt, and a slidable lifting component box is provided on the upper surface of the transmission boxes. The lifting component box is also symmetrically distributed on both sides of the conveyor belt. A pressure roller and a compaction pad are provided directly above the conveyor belt, and the compaction pad is evenly wrapped around the outer side surface of the pressure roller.

[0007] By adopting the above technical solution, the transmission box is equipped with a corresponding power structure to drive the conveyor belt at the side end to rotate, allowing the fabric to move on it. When the conveyor belt moves the fabric, it works in conjunction with the upper lifting component box, pressure rollers, and pressing pads to achieve a rolling printing function. The conveyor belt itself can stop at a certain position, and the pressure rollers and pressing pads inside the lifting component box can achieve press printing. Furthermore, the lifting component box itself can move to a certain extent, making the entire assembly highly flexible. It combines the dual functions of rolling and press printing, and the overall structure remains simple, easy to maintain, and low-cost, making it suitable for large-scale promotion.

[0008] In a preferred embodiment, a central shaft is provided on the inner side surface of the lifting component box, the lifting plate is slidably inserted into the side surface of the central shaft, a connecting pad is fixedly connected to one end of the lifting plate opposite to the central shaft, and a return spring is correspondingly provided at the bottom end of the lifting plate.

[0009] By adopting the above technical solution, when the entire printing assembly moves downward, it drives the lifting plate downward, which then contacts the return spring at the bottom and compresses it. After printing, the entire printing assembly can easily return to its original position. The lifting process is limited by the central shaft, ensuring relative stability and smoothness. The connecting pad serves as an intermediary component for connecting with the external printing structure.

[0010] In a preferred embodiment, a partition plate is provided on the inner side surface of the lifting component box, a lifting motor is provided at the bottom end of the partition plate, a lead screw is provided at the upper end of the lifting motor, the lead screw passes through the partition plate through an opening, and a traction nut is provided on the side surface of the lead screw.

[0011] By adopting the above technical solution, the partition plate divides the interior of the entire lifting component box into two spaces. A lifting motor is placed at the bottom of the partition plate as the power output structure for lifting. The motor drives the lead screw at the other end to rotate. After the lead screw rotates, it interacts with the traction nut to form the main lifting structure, which is used to drive the entire printing component downward so as to contact the fabric.

[0012] In a preferred embodiment, the axial end surface of the pressure roller is symmetrically provided with connecting cavities, and the connecting cavities are connected to connecting flanges by bolts. One end of the connecting flange relative to the connecting cavity is connected to a rotating shaft, and one end of the rotating shaft relative to the connecting flange is connected to a connecting pad.

[0013] By adopting the above technical solution, the pressure roller, as the middle structure, has a hollow internal structure connected to its side end. It is mainly used for connection. After being attached to the connecting flange, it is fixed with bolts. After fixing, it is convenient for the central shaft of the two ends to drive the entire pressure roller and the compaction pad to rotate. Furthermore, the compaction pad can be replaced to a certain extent after it is contaminated by the printing material.

[0014] In a preferred embodiment, a positioning box is provided on one end of the outer side surface of the rotating shaft near the connecting pad, a snap-fit ​​base is provided on the inner side surface of the positioning box, a snap-fit ​​frame is provided on the side end of the snap-fit ​​base, and a snap-fit ​​gear is provided on one end of the rotating shaft corresponding to the snap-fit ​​frame.

[0015] By adopting the above technical solution, the positioning box, as the main operating structure for locking and securing the entire printing component, has a rotatable locking frame on its internal locking base. The locking frame, as a horizontal plate with an opening, contacts the locking gear at the other end when it is tilted at a certain angle. When the locking gear is at one end of the central shaft of the rotating shaft, the locking frame contacts the teeth on the locking gear, causing it to lock and thus preventing the central shaft of the rotating shaft from rotating. This achieves the transformation from rolling printing to press printing mode. With a simple and lightweight structure, multiple functions are integrated and used at low cost.

[0016] In a preferred embodiment, a reset torsion spring is provided at the position of the locking frame corresponding to the locking base on its side end, a linkage rod is connected to the upper end of the locking frame, a traction rod is connected to one end of the linkage rod opposite to the locking frame, and a locking motor is connected to the side end of the traction rod.

[0017] By adopting the above technical solution, after the engagement between the locking frame and the locking gear is removed, the entire external printing device enters a rolling state. The reset torsion spring then returns the locking frame to a neutral position, thus not affecting the rotation of the locking gear. To achieve the engagement, the locking motor at the other end serves as the power output component, driving the pull rod to rotate. The pull rod, linkage rod, and locking frame are all connected by bolts, thus possessing a certain degree of rotation. Therefore, when the pull rod rotates, it drives the linkage rod to move, ultimately swinging the locking frame at a certain angle, bringing the locking frame into contact with the locking gear and achieving the engagement.

[0018] In a preferred embodiment, a guide groove is provided on the upper surface of the transmission box corresponding to the position of the lifting component box.

[0019] By adopting the above technical solution, the guide groove and the outside of the lifting component box are fitted together, and the electric push rod is set inside the transmission box to form a simple displacement structure, which facilitates the overall operation of printing.

[0020] In a preferred embodiment, a top frame is fixedly connected to the upper surface of the transmission box.

[0021] By adopting the above technical solution, the top frame is used to protect the overall structure of the internal printing.

[0022] In a preferred embodiment, a clothes rack is provided on the upper surface of the top frame.

[0023] By adopting the above technical solution, the printed clothes are collected together using a clothes rack, and the next step is carried out simultaneously.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] In this invention, the transmission box contains a corresponding power structure to drive the conveyor belt at the side end to rotate, allowing the fabric to move on it. When the conveyor belt moves the fabric, it works in conjunction with the upper lifting component box, pressure rollers, and pressing pads to achieve a rolling printing function. The conveyor belt itself can stop at a certain position, and the pressure rollers and pressing pads inside the lifting component box enable press printing. Furthermore, the lifting component box itself can move to a certain extent, making the entire assembly highly flexible. It combines the dual functions of rolling and press printing, while maintaining a simple, easy-to-maintain, and low-cost structure, making it suitable for large-scale promotion.

[0026] The pressure roller, as the middle structure, has a hollow internal cavity at its side end, which is mainly used for connection. After being attached to the connecting flange, it is fixed with bolts. After fixing, it is convenient for the central shaft at both ends to drive the entire pressure roller and the compaction pad to rotate. Furthermore, the compaction pad can be replaced to a certain extent after it is contaminated by the printing material.

[0027] The positioning box, as the main operating structure for locking and securing the entire printing component, has a rotatable locking frame on its internal locking base. The locking frame, as a horizontal plate with an opening, contacts the locking gear at the other end when tilted at a certain angle. When the locking gear is at one end of the central shaft of the rotating shaft, the locking frame contacts the teeth on the locking gear, causing it to lock and preventing the central shaft of the rotating shaft from rotating. This achieves the transformation from rolling printing to press printing mode. With its simple and lightweight structure, it integrates multiple functions at low cost. Attached Figure Description

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0036] Example: A fabric printing and pressing mechanism, wherein a transmission box 1 is symmetrically distributed on both sides of a conveyor belt 2, and a sliding lifting component box 3 is provided on the upper surface of the transmission box 1. The lifting component box 3 is also symmetrically distributed on both sides of the conveyor belt 2. A pressure roller 4 and a compaction pad 5 are provided directly above the conveyor belt 2. The compaction pad 5 is evenly wrapped around the outer side surface of the pressure roller 4.

[0037] The transmission box 1 contains a corresponding power structure to drive the side conveyor belt 2 to rotate, allowing the fabric to move on it. When the conveyor belt 2 moves the fabric, it works in conjunction with the upper lifting component box 3, pressure roller 4, and pressing pad 5 to achieve a rolling printing function. The conveyor belt 2 can also stop at a certain position, allowing for press printing using the pressure roller 4 and pressing pad 5 within the lifting component box 3. Furthermore, the lifting component box 3 itself can move to a certain extent, making the entire assembly highly flexible. It combines the functions of rolling and press printing, and the overall structure remains simple, easy to maintain, and low-cost, making it suitable for large-scale promotion.

[0038] A central shaft 6 is provided on the inner side surface of the lifting component box 3. The lifting plate 7 is slidably inserted into the side surface of the central shaft 6. A connecting pad 8 is fixedly connected to one end of the lifting plate 7 relative to the central shaft 6. A return spring 9 is provided at the bottom end of the lifting plate 7.

[0039] When the entire printing assembly moves downward, it causes the lifting plate 7 to move downward, contacting the return spring 9 at the bottom and compressing it. After printing, the entire printing assembly can easily return to its original position. The lifting process is limited by the central shaft 6, ensuring relative smoothness. The connecting pad 8 serves as an intermediary component for connecting with external printing structures.

[0040] A partition plate 12 is provided on the inner side surface of the lifting component box 3. A lifting motor 13 is provided at the bottom of the partition plate 12. A lead screw 10 is provided at the upper end of the lifting motor 13. The lead screw 10 passes through the partition plate 12 through the hole. A traction nut 11 is provided on the side surface of the lead screw 10.

[0041] The partition 12 divides the interior of the entire lifting component box 3 into two spaces. The bottom of the partition 12 is equipped with a lifting motor 13 as the power output structure for lifting. The motor drives the lead screw 10 at the other end to rotate. After the lead screw 10 rotates, it interacts with the traction nut 11 to form the main structure for lifting, which is used to drive the entire printing component downward so that it can contact the fabric.

[0042] The axial end side surface of the pressure roller 4 is symmetrically provided with connecting cavities 16. The connecting cavities 16 are connected to the connecting flanges 15 by bolts. The end of the connecting flanges 15 relative to the connecting cavities 16 is connected to the central shaft 14. The end of the central shaft 14 relative to the connecting flanges 15 is connected to the connecting pad 8.

[0043] The pressure roller 4 serves as the middle structure, and the connecting cavity 16 connected to its side end is an internally hollow structure, mainly used for connection. After being attached to the connecting flange 15, it is fixed with bolts. After fixing, it is convenient for the rotating shaft 14 at both ends to drive the entire pressure roller 4 and the compaction pad 5 to rotate. Furthermore, the compaction pad 5 can be replaced to a certain extent after being contaminated by the printing material.

[0044] A positioning box 17 is provided on the outer side surface of the rotating shaft 14 near the connecting pad 8. A snap-fit ​​base 18 is provided on the inner side surface of the positioning box 17. A snap-fit ​​frame 19 is provided on the side end of the snap-fit ​​base 18. A snap-fit ​​gear 24 is provided on the end of the rotating shaft 14 corresponding to the snap-fit ​​frame 19.

[0045] The positioning box 17 serves as the main operating structure for locking and securing the entire printing component. Inside, there is a rotatable locking frame 19 on the locking base 18. The locking frame 19 acts as a horizontal plate with an opening. When the locking frame 19 is tilted at a certain angle, it contacts the locking gear 24 at the other end. When the locking gear 24 is at one end of the central shaft 14 of the rotating shaft, the locking frame 19 contacts the teeth on the locking gear 24, causing it to lock and thus preventing the central shaft 14 of the rotating shaft from rotating. This achieves the transformation from rolling printing to press printing mode. With a simple and lightweight structure, multiple functions are integrated and used at low cost.

[0046] A reset torsion spring 20 is provided at the side end of the locking frame 19 corresponding to the position of the locking base 18. A linkage rod 21 is connected to the upper end of the locking frame 19. A traction rod 22 is connected to one end of the linkage rod 21 relative to the locking frame 19. A locking motor 23 is connected to the side end of the traction rod 22.

[0047] After the engagement between the locking frame 19 and the locking gear 24 is removed, the entire external printing device rolls. The return torsion spring 20 then returns the locking frame 19 to a neutral position, thus not affecting the rotation of the locking gear 24. To achieve the engagement, the locking motor 23 at the other end serves as the power output, driving the pull rod 22 to rotate. The pull rod 22, the linkage rod 21, and the locking frame 19 are all connected by bolts, thus possessing a certain degree of rotation. Therefore, when the pull rod 22 rotates, it moves the linkage rod 21, eventually swinging the locking frame 19 at a certain angle, bringing it into contact with the locking gear 24 and ultimately achieving engagement.

[0048] A guide groove 25 is provided on the upper surface of the transmission box 1 corresponding to the position of the lifting component box 3. By utilizing the fit between the guide groove 25 and the outside of the lifting component box 3, and in conjunction with the electric push rod provided inside the transmission box 1, a simple displacement structure can be formed, thereby facilitating the overall printing operation.

[0049] A top frame 26 is fixedly connected to the upper surface of the transmission box 1. The top frame 26 protects the overall structure of the internal printing process.

[0050] A garment rack 27 is provided on the upper surface of the top frame 26. The printed clothes are gathered together using the garment rack 27, and the next step is performed simultaneously.

[0051] The implementation principle of the fabric printing and pressing mechanism of the present invention is as follows: The transmission box 1 is equipped with a corresponding power structure to drive the conveyor belt 2 at the side to rotate, so that the fabric can move on it. When the conveyor belt 2 moves the fabric, it can form a rolling printing function in conjunction with the lifting component box 3, pressure roller 4, and pressing pad 5 at the upper end. The conveyor belt 2 can stop at a certain position, and the pressing printing can be realized by means of the pressure roller 4 and pressing pad 5 set in the lifting component box 3.

[0052] The pressure roller 4, as the middle structure, has a hollow internal cavity 16 connected to its side end, which is mainly used for connection. After being attached to the connecting flange 15, it is fixed with bolts. After being fixed, it is convenient for the rotating shaft 14 at both ends to drive the entire pressure roller 4 and the compaction pad 5 to rotate. Furthermore, the compaction pad 5 can be replaced to a certain extent after being contaminated by the printing material.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
