AI Technical Summary
Existing thermal transfer machines lack a structure that can smooth the printed paper from the middle to both sides, resulting in wrinkles in the middle of the printed paper and air affecting the flattening effect. They also lack a structure that repeatedly pulls the two sides of the paper, causing the two sides of the paper to warp, affecting the transfer quality.
A push-scraping mechanism and a reciprocating roller pressing mechanism are designed. The push-scraping mechanism uses multiple inclined scraping bars to push and scrape from the middle of the printed paper to both sides to eliminate wrinkles and air. The reciprocating roller pressing mechanism uses multiple pressing rollers to pull and squeeze both sides of the paper to ensure that the paper is flat.
It effectively eliminates wrinkles and air in the middle of the printed paper, avoids the warping of both sides of the paper, and improves the transfer effect.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of printing equipment, and more particularly to a thermal sublimation transfer machine with an auxiliary pressing and flattening structure. Background Art
[0002] Thermal transfer is an emerging printing process particularly suitable for producing small quantities of diverse, personalized and customized products, as well as printing designs containing full-color images or photographs. The process involves printing a digital design onto transfer paper using a printer using specialized transfer ink. A dedicated transfer machine then uses high temperature and high pressure to precisely transfer the design to the product surface, completing the product printing process.
[0003] For example, utility model patent CN214606554U discloses a flattening device for printing, which is convenient for conveying and flattening paper by setting two flattening conveying groups. By setting a water tank, a water pump and multiple nozzles, it is convenient to spray water mist on the flattening conveying group on the left to reduce wrinkles and wrinkle marks on the paper. By setting a heating plate, it is convenient to heat the flattening conveying group on the right. The flattening conveying group on the right heats and flattens the paper. In addition, the two flattening conveying groups convey and flatten the paper, reducing accidental injuries to the operator's fingers during direct pressing. However, the above-mentioned patent document only has the function of flattening the entire paper at one time. In actual use, due to the lack of a structure that can smooth the printing paper from the middle to the two sides, that is, the structure cannot be used to send the wrinkles and air in the printing paper out from between the two printing papers. As a result, the wrinkles and air in the middle of the two printing papers may affect the two printing papers when they are directly flattened. At the same time, there is also a lack of a structure that repeatedly pulls the two sides of the printing paper to stabilize them, which leads to the two sides of the flattened printing paper being warped, further affecting the transfer effect of the printing paper.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Embodiment 1: Due to the lack of a structure in the prior art that can smooth the printed paper from the middle to the sides, i.e., the inability to remove the wrinkles and air from between the two printed papers, the wrinkles and air in the middle of the two printed papers may cause an impact when the two printed papers are directly flattened. To solve this problem, the following technical solution is proposed: Refer to the instruction manual Figure 1-Figure 7 , a sublimation transfer machine that assists in pressing flat structures, such as Figure 1 and Figure 2 As shown, it includes a transfer machine feeding frame 1, a feeding roller 2 is provided on the top of the transfer machine feeding frame 1, a pressing roller 3 is provided on the other side of the transfer machine feeding frame 1, and a pushing and scraping mechanism 4 is provided on the top of the transfer machine feeding frame 1; like Figure 3 and Figure 4 As shown, the pushing and scraping mechanism 4 includes a motor 41 fixedly mounted on the top of the transfer machine feed frame 1, a rotating rod 42 is provided on one side of the motor 41, the rotating rod 42 is arranged in a horizontal state, and a reciprocating thread groove is respectively opened on both sides of the rotating rod 42, and the two reciprocating thread grooves are symmetrically arranged with each other; Two pushing gear racks 43 are threadedly connected to the two sides of the rotating rod 42. The two pushing gear racks 43 are symmetrically arranged. A support bracket 44 is slidably installed on one side of the two pushing gear racks 43. The support bracket 44 is fixedly installed on the top of the transfer machine feed rack 1. The two sides of the two pushing gear racks 43 are arranged in an inclined state. The motor 41 drives the rotating rod 42 to rotate, and then the rotating rod 42 causes the pushing gear racks 43 on both sides to move synchronously relative to each other through the reciprocating thread grooves on both sides, that is, the pushing gear racks 43 on both sides reciprocate towards or away from each other on the support bracket 44.
[0025] like Figure 3 and Figure 4 As shown, multiple half gears 45 are engaged on both sides of the two pushing gear racks 43, and the multiple half gears 45 are symmetrically arranged in pairs. A connecting bracket 46 is rotatably installed on the top of the half gear 45, and the connecting bracket 46 is fixedly installed on the top of the transfer machine feed rack 1. The two pushing gear racks 43 synchronously drive the multiple half gears 45, and the multiple half gears 45 rotate on the connecting bracket 46.
[0026] like Figure 4 and Figure 5 As shown, a scraper sleeve 47 is fixedly installed at the bottom of the half gear 45. There are multiple scraper sleeves 47, and the multiple scraper sleeves 47 are arranged in pairs corresponding to each other. The multiple scraper sleeves 47 are arranged in an inclined arrangement. Scrapers 48 are slidably installed inside the multiple scraper sleeves 47. The scrapers 48 are arranged vertically downward. A heavy pressure block 49 is fixedly installed on the top of the scraper 48. Then, the half gears 45 on both sides drive the scraper sleeves 47 and the scrapers 48 pressed downward by the heavy pressure block 49 to deflect synchronously. That is, the scrapers 48 on both sides push and scrape from the middle of the printing paper to both sides in turn, and can be arranged in a tilted manner so that the latter scraper 48 takes over the remaining area of the previous scraper 48, thereby achieving comprehensive scraping and pushing of the printing paper, thereby facilitating the elimination of wrinkles and air in the middle of the printing paper.
[0027] like Figure 4 and Figure 5 As shown, a rubber scraper strip 410 is rotatably installed at the bottom of the scraper 48. The rubber scraper strip 410 is set vertically downward. A baffle 411 is provided on one side of the rubber scraper strip 410. The baffle 411 is fixedly installed on the outer wall of the scraper 48. When the scraper 48 deflects and drives the rubber scraper strip 410 to scrape outward, the rubber scraper strip 410 is restricted by the baffle 411 to remain vertically attached to the printed paper. When the scraper 48 moves back and drives the rubber scraper strip 410 to deflect inward, the rubber scraper strip 410 is not restricted and is free to tilt up, thereby avoiding bringing back the scraped printed paper and causing an impact.
[0028] During specific implementation, the motor 41 drives the rotating rod 42 to rotate, and then the rotating rod 42 causes the pushing gear racks 43 on both sides to move synchronously relative to each other through the reciprocating thread grooves on both sides, that is, the pushing gear racks 43 on both sides reciprocate towards or away from each other on the support bracket 44, and the two pushing gear racks 43 synchronously drive multiple half gears 45, which then rotate on the connecting bracket 46, and then the half gears 45 on both sides drive the scraper sleeve 47 and the scraper 48 pressed downward by the weight block 49 to deflect synchronously; That is, when the scrapers 48 on both sides drive the rubber scraper 410 to scrape outward, the rubber scraper 410 is restricted by the baffle 411 to remain vertically attached to the printed paper, thereby scraping from the middle of the printed paper to both sides in turn, and through multiple inclined arrangements, the rear scraper 48 can take over the area left by the previous scraper 48, so as to achieve comprehensive scraping and pushing of the printed paper, thereby facilitating the elimination of wrinkles and air in the middle of the printed paper. When the scraper 48 moves back and drives the rubber scraper 410 to deflect inward, the rubber scraper 410 is not restricted and can be freely tilted up, thereby avoiding bringing back the scraped printed paper and causing an impact.
[0029] Embodiment 2: In view of the fact that the prior art lacks a structure for repeatedly pulling the two sides of the printing paper to stabilize the two sides, which causes the two sides of the flattened printing paper to warp, further affecting the transfer effect of the printing paper, to solve this problem, the following technical solution is proposed: like Figure 6 and Figure 7As shown, a reciprocating rolling mechanism 5 is provided on one side of the support bracket 44, and the reciprocating rolling mechanism 5 includes two connecting plates 51 slidably mounted on one side of the support bracket 44, and the two connecting plates 51 are symmetrically arranged. The two connecting plates 51 are respectively fixedly mounted on the top of the two pushing gear racks 43, and a groove pressing sleeve 52 is respectively fixedly mounted on one side of the two connecting plates 51, and the two groove pressing sleeves 52 are symmetrically arranged. When the two pushing gear racks 43 move relative to each other, the two connecting plates 51 are driven to move synchronously, and the two connecting plates 51 drive the groove pressing sleeve 52 to move synchronously.
[0030] like Figure 6 and Figure 7 As shown, a plurality of limit springs 53 are fixedly installed on the inner walls of the two groove pressing sleeves 52, and a belt plate frame 54 is fixedly installed on the bottom of the plurality of limit springs 53. The belt plate frame 54 is slidably installed on the inner wall of the groove pressing sleeve 52, and a plurality of pressure rollers 55 are rotatably installed on the outer wall of the belt plate frame 54. The plurality of pressure rollers 55 are staggered with each other, and then when the two groove pressing sleeves 52 move synchronously to both sides, the two groove pressing sleeves 52 drive the belt plate frame 54 and the plurality of pressure rollers 55 at the bottom thereof to move synchronously to both sides through the limit springs 53, that is, the plurality of pressure rollers 55 synchronously stretch the two sides of the printed paper outward.
[0031] like Figure 6 and Figure 7 As shown, a metal rod 56 is fixedly installed on one side of the plate rack 54. The metal rod 56 is set in a horizontal state. A slide groove 57 is provided on one side of the metal rod 56. The slide groove 57 is opened on the outer wall of the support bracket 44. The slide groove 57 is set in a circular ring shape. When the plate racks 54 on both sides move back and forth, the metal rod 56 on one side of the plate rack 54 moves in the slide groove 57.
[0032] like Figure 6 and Figure 7 As shown, magnet blocks 58 are fixedly installed on the inner walls of both sides of the slide 57. The magnet blocks 58 are arranged in an arc shape. The magnet blocks 58 and the metal rods 56 are arranged corresponding to each other. After the belt plate frame 54 moves outward to the outermost side, the metal rods 56 are squeezed by the magnet blocks 58 and the inner walls of the slide 57 and lifted upward into the upper groove of the slide 57. At this time, the belt plate frame 54 drives the multiple pressure rollers 55 to lift synchronously, thereby preventing the multiple pressure rollers 55 from pulling the two sides of the printed paper when moving back.
[0033] In a specific implementation, when the two pushing gear racks 43 move relative to each other, they drive the two connecting plates 51 to move synchronously, and the two connecting plates 51 drive the groove pressing sleeves 52 to move synchronously. Then, when the two groove pressing sleeves 52 move synchronously to both sides, the two groove pressing sleeves 52 drive the belt plate rack 54 and multiple pressing rollers 55 at their bottom to move synchronously to both sides through the limit springs 53. That is, multiple pressure rollers 55 synchronously stretch the two sides of the printed paper outward. When the belt plate racks 54 on both sides move back and forth, the metal rod 56 on one side of the belt plate rack 54 moves in the slide groove 57. After the belt plate rack 54 moves outward to the outermost side, the metal rod 56 is squeezed by the magnet block 58 and the inner wall of the slide groove 57 and lifted upward into the upper groove of the slide groove 57. At this time, the belt plate rack 54 drives the multiple pressure rollers 55 to be lifted synchronously, thereby preventing the multiple pressure rollers 55 from pulling the two sides of the printed paper when moving back.
