Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a thermal transfer machine with a limiting structure. Background Art

[0002] Thermal transfer machine is a general term for machines used in thermal transfer technology. Thermal transfer machines include flat heat press machines, high-pressure heat press machines, shaking head heat press machines, cup baking machines, tray baking machines, cap baking machines and other thermal transfer machines. The printing range is very wide, including flat heat presses, as well as round and curved heat presses such as cups, plates and hats. Thermal transfer is a new technology that has just been put on the right track. In the process of producing handbags, it is also necessary to transfer the pattern on the thermal transfer film to the handbag through thermal transfer technology. However, when transferring the handbag, the two ends of the transfer film are often connected by a unwinding roller and a winding roller, and the handbag is manually placed on the workbench, which makes the handbag easy to deviate during thermal transfer, affecting the final transfer effect. Therefore, we have launched a thermal transfer machine with a limited position structure.

[0003] The existing technology has the following problems: 1. When the existing thermal transfer machine prints on the handbag, the handbag is directly placed under the thermal transfer plate manually, and the position of the handbag is not uniform, resulting in different positions of the final printed pattern, affecting product quality; 2. When the existing thermal transfer machine prints on the handbag, wrinkles may appear on the surface of the handbag, resulting in incomplete interlayer transfer of the pattern. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a thermal transfer machine with a limited position structure, comprising a transfer table 1, the top of the transfer table 1 is fixedly connected to the top plate 2 through four supporting columns, a transfer assembly 3 is fixedly connected to the middle part of the bottom surface of the top plate 2, a leveling assembly 4 is sleeved on the outer side of the transfer assembly 3, and a limiting assembly 5 is provided under the transfer table 1, the transfer assembly 3 comprises an electric push rod 301 fixedly connected to the middle part of the bottom surface of the top plate 2, the output end of the electric push rod 301 is fixedly connected to a transfer disk 302, and two lifting rods 303 are fixedly connected to the outer side of the output rod of the electric push rod 301; when in use, the transfer film is moved by an external winding roller and an unwinding roller, the transfer film is passed between the top surface of the transfer table 1 and the bottom surface of the transfer disk 302, and then a handbag that needs to be thermally transferred is placed on the transfer table 1, the electric push rod 301 drives the transfer disk 302 to press down and heat, and the pattern on the transfer film is transferred to the handbag.

[0024] In this embodiment, Figure 1 and Figure 2As shown, the limit assembly 5 includes four first slide grooves 501 opened on the surface of the transfer table 1, and the first sliders 502 are slidably connected inside the four first slide grooves 501. The first sliders 502 are in the shape of an "I". The bottom of the first slider 502 is hinged to the top of the first connecting rod 503, and the bottom end of the first connecting rod 503 is hinged to the top surface of the lifting plate 504. Two vertical rods 505 are fixedly connected to both sides of the lifting plate 504. The two lifting rods 303 are pushed downward by the electric push rod 301, and the lifting rods 303 will contact the top surface of the lifting ring 406, thereby The lifting cylinder 4010 drives the lifting frame 401 to move downward, and finally drives the lifting plate 504 to move downward. When the lifting plate 504 moves downward, it will drive the first connecting rod 503 to move downward. At this time, the first sliding block 502 hinged at the top of the first connecting rod 503 will slide along the first sliding groove 501 toward the middle of the transfer table 1. Since the four first connecting rods 503 are of the same length and angle, the four first connecting rods 503 will drive the four first sliding blocks 502 to approach or move away at the same time, thereby limiting the handbag above the transfer table 1 and automatically positioning the handbag to the middle of the transfer table 1 to ensure that the pattern on each handbag is located at the same position.

[0025] In this embodiment, Figure 2 and Figure 4As shown, the leveling assembly 4 includes a lifting frame 401 fixedly connected between the top ends of the two vertical rods 505, four second slide grooves 402 are provided at the corners of the top surface of the lifting frame 401, and the middle parts of the four second slide grooves 402 are slidably connected with second sliders 403, the second sliders 403 are in the shape of an "I", and the bottom surface of the second slider 403 is located below the bottom surface of the lifting frame 401, and the bottom of the second slider 403 is fixedly connected with a leveling block 404, the leveling block 404 is in a right angle shape, and the top of the second slider 403 The second connecting rod 405 is hinged at the bottom, the top of the second connecting rod 405 is hinged to the outside of the lifting ring 406, the bottom surface of the lifting ring 406 is fixedly connected with a spring 407, the bottom end of the spring 407 is fixedly connected to the top surface of the fixing ring 408, the outside of the fixing ring 408 is fixedly connected with four L rods 409, the bottom ends of the four L rods 409 are welded to the top surface of the lifting frame 401, the fixing ring 408 is fixedly connected to the bottom end of the lifting cylinder 4010, and the outer wall of the lifting cylinder 4010 is provided with two strip grooves 4011, the two lifting rods 303 are slidably connected to the middle of the two strip grooves 4011, the output end of the electric push rod 301 is located in the middle of the lifting cylinder 4010 and extends to the bottom of the lifting cylinder 4010. The outer wall of the lifting cylinder 4010 and the inner wall of the lifting ring 406 do not contact each other. A square opening is opened in the middle of the lifting frame 401, and the internal size structure of the square opening is larger than the external size structure of the transfer plate 302; when the electric push rod 301 drives the lifting frame 401 to move downward , the leveling block 404 below the lifting frame 401 will first contact the handbag on the transfer table 1, and then the electric push rod 301 will continue to extend. At this time, the lifting rod 303 will push the lifting ring 406 to move downward. When the lifting ring 406 moves downward, it will drive the second slider 403 at the corner of the lifting frame 401 to move away through the second connecting rod 405. The second slider 403 moves away to drive the bottom leveling block 404 to stretch the dead corner of the handbag, so as to achieve the purpose of leveling and prevent the handbag from wrinkling during the transfer process and affecting the transfer.

[0026] The use method and advantages of the utility model: When the heat transfer machine with a limited position structure is used, the working process is as follows:

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, firstly, the handbag to be transferred is placed between the four first sliders 502 on the top surface of the transfer table 1, and then the transfer film with the pattern is located in the middle of the top of the transfer table 1 under the action of the external conveying mechanism. At this time, the electric push rod 301 is started to push the lifting rod 303 and the transfer plate 302 to move downward at the same time. During the downward movement of the lifting rod 303, it will first contact the top surface of the lifting ring 406. At this time, the lifting rod 303 squeezes the lifting ring 406 to move downward. Note that at this time, the lifting ring 406 and the fixed ring 408 are The distance between the lifting and lowering parts remains unchanged, and the lifting ring 406 moves downward, which drives the lifting cylinder 4010 to move downward synchronously through the spring 407 and the fixing ring 408. Moreover, because the lifting cylinder 4010 is connected to the lifting frame 401 through the L rod 409, the lifting frame 401 can be moved downward. Since the leveling block 404 under the lifting frame 401 is located under the transfer plate 302 under normal conditions, when the leveling block 404 moves downward with the lifting frame 401 and contacts the top surface of the handbag, the transfer plate 302 has not yet contacted the top surface of the handbag. The push rod 301 can still continue to extend to drive the transfer plate 302 and the lifting rod 303 to move downward. The lifting rod 303 will squeeze the spring 407 through the lifting ring 406. At this time, the distance between the lifting ring 406 and the fixed ring 408 is shortened. As the lifting ring 406 moves downward, the four second sliders 403 will be pushed away from each other through the second connecting rod 405. The second sliders 403 drive the flattening block 404 at the bottom to straighten the four corners of the handbag, so as to eliminate the wrinkles on the surface of the handbag and prevent the handbag from being damaged during the transfer process. The appearance of wrinkles causes the transfer pattern to be incomplete, and when the lifting frame 401 descends with the electric push rod 301, the lifting frame 401 will use the vertical rod 505 to drive the lifting plate 504 to move downward. The downward movement of the lifting plate 504 will drive the four first sliders 502 to slide along the first slide groove 501 toward the middle of the transfer table 1 at the same time through the first connecting rod 503, thereby limiting the handbag above the transfer table 1 and automatically positioning the handbag to the middle of the transfer table 1, ensuring that the pattern on each handbag is located in the same position.
