Description

Technical Field

[0001] The utility model relates to the technical field of heat transfer printing, in particular to a lifting device for a heat transfer printing dye tank. Background Art

[0002] Heat transfer printing is a new printing process. The printing method of this process is divided into two major parts: transfer film printing and transfer processing. Transfer film printing uses dot printing to pre-print patterns on the surface of the film. Then, through transfer processing, that is, through a heat transfer printing machine, the patterns on the transfer film are transferred to the surface of the product at one time. The printing layer of the heat transfer film generally uses intaglio printing. The base film roll coated with a release agent passes through the middle of the printing pressure roller and the printing plate roller. The printing plate roller rotates in the dye tank to print the text and graphics. Therefore, the continuous supply of dye is an important guarantee for efficient printing. A heat transfer printing dye tank lifting device will be used during the printing process;

[0003] For this reason, the patent with the authorization announcement number CN208991132U discloses a heat transfer printing dye tank lifting device, which includes a dye tank, a handwheel, a rotating shaft, and a connecting rod. The dye tank is arranged between the frames. Support columns are arranged on both sides below the dye tank. The support columns are arranged in the grooves of the support seats in a slidable state. The support seats are arranged on the frames. Sawteeth are provided on the support columns. The support columns are linked with the driven gears arranged at both ends of the connecting rod through the sawteeth. A driving gear is arranged at the end of the connecting rod extending from one side of the frame. The driving gear meshes with the thread on the rotating shaft. The handwheel controls the rotation of the rotating shaft. After adopting the above scheme, the relative height of the dye tank can be adjusted at any time;

[0004] The above heat transfer printing dye tank lifting device can adjust the height of the dye tank in real time by rotating the handwheel, so as to prevent the rod-shaped film printing from detaching from the dye or being too immersed in the dye and causing overflow. However, when using this device, it is necessary to manually monitor and adjust the height of the dye tank in real time, which is time-consuming and laborious. Moreover, the protective measures of this lifting device are insufficient. The dye tank is filled with dye liquid. Affected by its gravity, when there is more dye, the dye tank will drop.

The top of the roller abuts against the inner side wall of the top of the moving groove. The moving seat is threadedly connected to the threaded rod.

[0012] Preferably, at the corner positions of the bottom end of the dye tank body, positioning grooves are provided. At both ends of the top of the dye tank body, reserved grooves are provided. At both ends of the bottom of the dye tank body, handles are uniformly fixedly installed. On one side of the top of the dye tank body, a nozzle is fixedly installed.

[0013] Preferably, the inner side wall of the positioning groove fits with the outer side wall of the positioning block. The positioning groove and the positioning block are hemispherical.

[0014] Preferably, one end of the transmission shaft extends into the interior of the side plate and is rotatably connected to the side plate. The other end of the transmission shaft passes through the side plate and a pulley is fixedly installed. Both ends of the printing pressure roller are rotatably connected to the side plate through connecting shafts.

[0017] The advantages of a thermal transfer dye tank lifting device provided by the present invention are as follows:

[0018] By providing a lifting structure, when the servo motor is started, the servo motor drives the threaded rod to rotate, causing the threaded rod to drive the moving seat to slide on the top of the slide rail. At the same time, the moving seat drives the roller to move inside the moving groove through the fixed shaft, so that the roller pushes the support plate to move up and down. Furthermore, the support plate drives the dye tank body to move up and down through the lifting seat. Under the action of the slide rail and the threaded rod, the moving seat can stably support the dye tank body, avoiding the dye tank body from sliding down due to gravity, thereby improving the stability of the thermal transfer dye tank lifting device during use;

[0019] By providing a monitoring structure, the lowest point of the photoelectric liquid level sensor and the lowest point of the printing plate cylinder are located on the same horizontal plane. When the dye tank body moves upward after being filled with dye, the photoelectric liquid level sensor moves into the liquid level box and contacts the dye. At this time, the bottom of the printing plate cylinder contacts the dye. As the dye is used, the liquid level drops, and the photoelectric liquid level sensor starts the servo motor through the single-chip microcomputer, causing the dye tank body to continue to move upward until the liquid level contacts the bottom of the printing plate cylinder, realizing the functions of automatically monitoring the liquid level position and automatically lifting of the device, thereby improving the convenience of the thermal transfer dye tank lifting device during use.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1 - 6 , a thermal transfer dye tank lifting device provided by the present utility model includes a base 1.

[0029] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown in the figure, side plates 11 are fixed on both sides of the top end of the base 1. Grooves 12 are formed on one side inside the side plates 11. A lifting structure 2 is installed at the top end of the base 1 on one side of the groove 12. The lifting structure 2 includes a lifting seat 21, guide rods 22, a support plate 23, a support 24, a slide rail 25 and a moving seat 26. The lifting seat 21 is located above the base 1 on one side of the groove 12. Support plates 23 are fixed on both sides of the bottom end of the lifting seat 21. Guide rods 22 are fixed at the corner positions of the bottom end of the lifting seat 21. The slide rail 25 is fixed at the top end of the base 1 directly below the lifting seat 21. Supports 24 are fixed at the top ends of the base 1 at both ends of the slide rail 25. A moving seat 26 is arranged on the top of the slide rail 25. Positioning blocks 211 are fixed at the corner positions of the top end of the lifting seat 21. Guide seats 221 are arranged on the outer sides of the guide rods 22. Moving grooves 231 are arranged inside the support plates 23. A servo motor 241 is installed on one side of the top of the support 24. A threaded rod 261 passes through the inside of the moving seat 26. Fixed shafts 262 are fixed on both sides of the top of the moving seat 26. One ends of the fixed shafts 262 extend into the inside of the moving groove 231 and are provided with rollers 263. The bottom end of the guide seat 221 is fixedly connected to the top end of the base 1. The guide seat 221 is slidably connected to the guide rod 22. The middle part of the moving groove 231 is inclined, and both ends of the moving groove 231 are horizontal. A chute is formed at the bottom end of the moving seat 26. The moving seat 26 and the slide rail 25 form a sliding structure through the chute. One end of the threaded rod 261 extends into the inside of the support 24 and is rotatably connected to the support 24. The other end of the threaded rod 261 passes through the support 24 and is fixedly connected to the output end of the servo motor 241. The top of the roller 263 abuts against the inner side wall of the top of the moving groove 231. The moving seat 26 is threadedly connected to the threaded rod 261.

[0030] When the servo motor 241 is started, the servo motor 241 drives the threaded rod 261 to rotate, so that the threaded rod 261 drives the moving seat 26 to slide on the top of the slide rail 25. At the same time, the moving seat 26 drives the roller 263 to move inside the moving groove 231 through the fixed shaft 262, so that the roller 263 pushes the support plate 23 to move up and down. Furthermore, the support plate 23 drives the dye tank body 3 to move up and down through the lifting seat 21. The roller 263 is subjected to a downward pressure and a horizontal thrust in the moving groove 231, while the roller 263 is subjected to an upward supporting force from the slide rail 25 and the moving seat 26. Horizontally, the moving seat 26 is threadedly connected to the threaded rod 261, and there is a certain frictional force between the slide rail 25 and the moving seat 26 horizontally. Therefore, the roller 263 can stably support the dye tank body 3 inside the moving groove 231, avoiding the dye tank body 3 from sliding down under the influence of gravity.

[0031] Refer to Figure 1 、 Figure 5 and Figure 6As shown, a dye tank body 3 is provided at the top of the lifting seat 21. Positioning grooves 34 are formed at the corner positions at the bottom end of the dye tank body 3. Reserved grooves 31 are formed at both ends of the top of the dye tank body 3. Handles 32 are evenly fixed at both ends of the bottom of the dye tank body 3. A nozzle 33 is fixed on one side of the top of the dye tank body 3. The inner side wall of the positioning groove 34 fits with the outer side wall of the positioning block 211. The positioning groove 34 and the positioning block 211 are hemispherical.

[0032] Under the action of the groove 12, the dye tank body 3 can be lifted out from the top of the lifting seat 21 through the handle 32 for cleaning. Under the action of the positioning block 211 and the positioning groove 34, it is convenient for the dye tank body 3 to be quickly positioned when placed and prevents the dye tank body 3 from slipping sideways during use. The nozzle 33 facilitates adding dye into the dye tank body 3.

[0033] Refer to Figure 3 and Figure 4 As shown, a printing plate roller 4 is provided directly above the dye tank body 3. Transmission shafts 41 are fixed at both ends of the printing plate roller 4. A printing pressure roller 5 is provided at the top of the printing plate roller 4. One end of the transmission shaft 41 extends into the side plate 11 and is rotatably connected to the side plate 11. The other end of the transmission shaft 41 passes through the side plate 11 and is fixed with a pulley 42. Both ends of the printing pressure roller 5 are rotatably connected to the side plate 11 through connecting shafts. A monitoring structure 6 is fixed on the inner wall of the side plate 11 at the top end of the groove 12. The monitoring structure 6 includes a liquid level box 61, a photoelectric liquid level sensor 62, and a fixing bracket 63. The fixing bracket 63 is fixed on the inner wall of the side plate 11 on one side of the groove 12. The photoelectric liquid level sensor 62 is installed at the bottom end of the fixing bracket 63. The photoelectric liquid level sensor 62 is a new type of non-contact point liquid level measurement and control device developed based on the principle of light reflection and refraction at the interface of two different media. The output of the liquid level is only related to whether the photoelectric probe contacts the liquid surface. Therefore, the photoelectric liquid level sensor 62 has a simple structure, high positioning accuracy, high sensitivity, and good corrosion resistance. A liquid level box 61 is installed at one end of the bottom of the dye tank body 3 directly below the photoelectric liquid level sensor 62. The liquid level box 61 is communicated with the bottom of the dye tank body 3. The fixing bracket 63 is in an "L" shape. The output end of the photoelectric liquid level sensor 62 is electrically connected to the input end of the servo motor 241 through a single-chip microcomputer. The lowest point of the photoelectric liquid level sensor 62 and the lowest point of the printing plate roller 4 are located on the same horizontal plane.

[0034] Install the dye tank body 3 filled with dye on the top of the lifting seat 21. The liquid level of the dye inside the dye tank body 3 will be flush with the liquid level inside the liquid level box 61. Start the servo motor 241 to move the dye tank body 3 upward. When the photoelectric liquid level sensor 62 moves into the liquid level box 61 and contacts the dye, the lowest point of the photoelectric liquid level sensor 62 and the lowest point of the printing plate cylinder 4 are located on the same horizontal plane. At this time, the bottom of the printing plate cylinder 4 contacts the dye. As the dye is used, the liquid level drops. The photoelectric liquid level sensor 62 will start the servo motor 241 through the single-chip microcomputer, and move the dye tank body 3 upward continuously until the liquid level contacts the bottom of the printing plate cylinder 4.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
