Description

Technical Field

[0001] This utility model relates to the field of shoe upper printing technology, and in particular to a high-frequency machine for shoe upper printing. Background Technology

[0002] In shoe manufacturing, it is common to print patterns and logos on the shoe upper. Current shoe upper printing generally uses a high-frequency machine, which uses a high-frequency electromagnetic field to cause the molecules inside the material to collide violently and generate high temperatures. Combined with a pressing structure and a printing template, the desired pattern is printed on the shoe upper.

[0003] Currently, the printing machines used for shoe uppers are made of aluminum plates. Their function is to conduct the electrothermal energy of the high-frequency equipment, stably withstand the extremely high mechanical pressure and vibration of the high-frequency equipment, and effectively resist the chemical corrosion and oxidation generated by the high-frequency equipment during operation. Since shoe uppers are generally thin, a layer of insulating paper or cloth is often needed before printing on the aluminum plate to prevent the pressure plate of the high-frequency equipment and the aluminum plate from melting together and causing a short circuit. At the same time, the insulating paper or cloth can also effectively prevent the shoe upper from being punctured, thus protecting the safety of the shoe upper.

[0004] The aforementioned insulating paper or fabric is usually placed directly on the aluminum plate. During the movement of the shoe upper, the insulating paper or fabric is very prone to shifting and moving with the shoe upper. Therefore, workers often need to manually adjust the position of the insulating paper or fabric before each printing process, which leads to longer shoe upper preparation time and reduced printing efficiency. At the same time, during the shoe upper printing process, the same position of the insulating paper or fabric is subjected to frequent and continuous pressure and heat, resulting in a short service life of the insulating paper or fabric. Workers often need to replace the insulating paper or fabric with new ones, which increases the cost of shoe upper printing. Utility Model Content

[0005] The purpose of this invention is to provide a high-frequency printing machine for shoe uppers, which has the effect of preventing the insulating fabric from shifting and automatically changing the position of the insulating fabric under pressure and heat.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-frequency printing machine for shoe uppers, comprising a table, four table legs fixed to the bottom of the table, a high-frequency printing device mounted on the table, an aluminum plate fixed on the table and used in conjunction with the high-frequency printing device to process shoe uppers, a rotating roller with its two ends rotatably connected to a pair of table legs, a worm gear reducer motor driving the rotating roller to rotate, a pair of sliders slidably disposed on another pair of table legs, a sliding assembly controlling the sliders to slide up and down relative to the table legs, a tension roller with its two ends rotatably connected to the two sliders and parallel to the rotating roller, and an insulating cloth strip sleeved on the aluminum plate, the rotating roller, and the tension roller. The rotating roller and the tension roller are located on both sides of the aluminum plate. The table has elongated holes on both sides of the aluminum plate for the insulating cloth strip to pass through. The worm gear reducer motor is fixed to one table leg and located on both sides of the table leg with the rotating roller. One end of the rotating roller rotates through the table leg and is fixedly connected to the output end of the worm gear reducer motor.

[0007] A further feature of this invention is that the bottom of the tabletop is rotatably mounted on a pair of guide rollers, which are parallel to the rotating rollers or tension rollers and located between two elongated holes. The two guide rollers contact the outer side of the insulating tape and, together with the aluminum plate, the rotating rollers and the tension rollers, stretch the insulating tape into an inverted U-shape.

[0008] A further feature of this invention is that triangular bracing plates are fixedly connected between one side of each of the four table legs and the bottom of the tabletop, and two pairs of triangular bracing plates are rotatably connected to the two ends of the two guide rollers.

[0009] A further feature of this invention is that the top of the tabletop has a groove for embedding an aluminum plate, and the upper surface of the aluminum plate is flush with the upper surface of the tabletop.

[0010] A further feature of this invention is that a transition roller is rotatably disposed within the elongated hole, and the top of the table is tangent to the roller surface of the transition roller, and the insulating cloth tape is sleeved on the transition roller in the two elongated holes.

[0011] A further feature of this invention is that the table leg is provided with a long groove for the slider to slide up and down.

[0012] A further feature of this invention is that the sliding assembly includes a lead screw that is vertically rotatably disposed within a long sliding groove, a nut fixed to the middle of the slider and threadedly connected to the lead screw, a rotating rod fixed to the upper end of the lead screw and rotatably passing through the table leg and the tabletop, and a knob fixed to the top of the rotating rod.

[0013] A further feature of this invention is that the rotating roller, tensioning roller, and guide roller are respectively fixedly fitted with limiting retaining rings on both sides of the insulating tape.

[0014] A further feature of this invention is that a long strip of bristles is fixedly provided on the inner wall of the elongated hole, and the long strip of bristles cleans the outer surface of the insulating tape.

[0015] A further feature of this invention is that a pair of protective covers are fixedly installed on the top of the tabletop, each covering one of the two elongated holes, and an opening is provided on the side of the protective cover near the aluminum plate for an insulating belt to pass through.

[0016] The beneficial effects of this utility model are as follows: By adopting the above technical solution, when printing on shoe uppers, the shoe upper to be processed and the printing template are first stacked on the insulating cloth tape above the aluminum plate, and then manually moved to the underside of the pressure plate of the high-frequency printing equipment. Since the insulating cloth tape is stretched into an inverted U-shape by the tension roller, rotating roller, guide roller, and transition roller, and the rotating roller remains stationary due to self-locking when the worm gear reducer motor stops, moving or adjusting the position of the shoe upper at this time will not easily cause the insulating cloth tape to move or shift randomly. Then, after the shoe upper and printing template are adjusted to the appropriate position, the printing process can be started. The high-frequency printing equipment prints on the shoe upper. After the printing is completed, the worm gear reducer motor drives the rotating roller to rotate, which allows the insulating tape to move relative to the aluminum plate. This not only changes the position of the insulating tape that was heated and pressed with the position that was not heated and pressed, but also quickly removes the printing template, which is at a higher temperature, and the printed shoe upper from the bottom of the pressure plate of the high-frequency printing equipment. This effectively extends the life of the insulating tape and simplifies the unloading process, preventing workers from being burned when they rush to remove the printing template and the inclined surface.

[0021] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: A high-frequency printing machine for shoe uppers, such as... Figure 1 , Figure 2 As shown, the system includes a tabletop 1, four table legs 2 fixed to the bottom of the tabletop 1, a high-frequency printing device 3 mounted on the tabletop 1, an aluminum plate 4 fixed to the tabletop 1 and used in conjunction with the high-frequency printing device 3 to process shoe uppers, a rotating roller 5 with each end rotatably connected to a pair of table legs 2, a worm gear reducer motor 6 driving the rotating roller 5 to rotate, a pair of sliders 7 slidably mounted on another pair of table legs 2, a sliding assembly 8 controlling the sliders 7 to slide up and down relative to the table legs 2, and two sliders 7 rotatably connected to each other at both ends. The parallel rotating roller 5 has a tension roller 9, and an insulating cloth strip 10 is sleeved on the aluminum plate 4, the rotating roller 5, and the tension roller 9. The rotating roller 5 and the tension roller 9 are located on both sides of the aluminum plate 4. The table board 1 is located on both sides of the aluminum plate 4 and has elongated holes 1a through which the insulating cloth strip 10 passes. The worm gear reducer motor 6 is fixed on a table leg 2 and is located on both sides of the table leg 2 along with the rotating roller 5. One end of the rotating roller 5 rotates through the table leg 2 and is fixedly connected to the output end of the worm gear reducer motor 6.

[0023] Furthermore, the bottom of the tabletop 1 is rotatably mounted on a pair of guide rollers 11. These guide rollers 11 are parallel to the rotating roller 5 or the tensioning roller 9 and are located between two elongated holes 1a. The two guide rollers 11 contact the outer side of the insulating tape 10 and, together with the aluminum plate 4, the rotating roller 5, and the tensioning roller 9, stretch the insulating tape 10 into an inverted U-shape. By employing the guide rollers 11, not only can the insulating tape 10 be further tensioned, but also, in conjunction with the aluminum plate 4, the rotating roller 5, and the tensioning roller 9, the insulating tape 10 can be stretched into an inverted U-shape. This also reduces the usable space of the insulating tape 10 at the bottom of the tabletop 1, thus facilitating the worker's leg extension and the storage of miscellaneous items.

[0024] Furthermore, triangular bracing plates 12 are fixedly connected between one side of each of the four table legs 2 and the bottom of the tabletop 1, and two pairs of triangular bracing plates 12 are rotatably connected to the two ends of the two guide rollers 11. By using the above-mentioned triangular bracing plates 12, not only can the connection stability between the table legs 2 and the tabletop 1 be further improved, but it can also provide support for the rotation of the guide rollers 11.

[0025] Furthermore, the top of the tabletop 1 is provided with a groove 1b for embedding the aluminum plate 4, and the upper surface of the aluminum plate 4 is flush with the upper surface of the tabletop 1. By using the above-mentioned groove 1b, not only can the aluminum plate 4 be stably fixed to the top of the tabletop 1, but it can also facilitate the disassembly and replacement of the aluminum plate 4 by the staff.

[0026] Furthermore, a transition roller 13 is rotatably disposed within the elongated hole 1a, and the top of the table plate 1 is tangent to the roller surface of the transition roller 13. The insulating tape 10 is sleeved on the transition roller 13 in the two elongated holes 1a. By using the aforementioned transition roller 13, not only can the insulating tape 10 be further tensioned, but it can also prevent the insulating tape 10 from rubbing against the edge of the elongated hole 1a, which would cause wear on the inner surface of the insulating tape 10, or even break the insulating tape 10.

[0027] Furthermore, the table leg 2 is provided with a long groove 2a for the slider 7 to slide up and down, which can ensure the sliding stability of the slider 7.

[0028] Furthermore, the sliding assembly 8 includes a lead screw 8a vertically rotatably disposed within the elongated slide groove 2a, a nut 8b fixed to the middle of the slider 7 and threadedly connected to the lead screw 8a, a rotating rod 8c fixed to the upper end of the lead screw 8a and rotatably passing through the table leg 2 and the tabletop 1, and a knob 8d fixed to the top of the rotating rod 8c. By employing the above-mentioned sliding assembly 8, when it is necessary to adjust the height of the tension roller 9, firstly, both knobs 8d on the top of the tabletop 1 are rotated simultaneously with both hands, so that the two knobs 8d drive the lead screw 8a within the elongated slide groove 2a to rotate through the rotating rod 8c. Then, the nut 8b threadedly connected to the lead screw 8a will drive the slider 7 to slide up and down relative to the elongated slide groove 2a along the direction of the lead screw 8a. Finally, the tension roller 9, which is rotatably connected to the two sliders 7 at both ends, will rise or fall under the sliding of the two sliders 7, thereby adjusting the tension of the insulating tape 10 to avoid the insulating tape 10 being too loose or too tight.

[0029] Furthermore, the rotating roller 5, tension roller 9 and guide roller 11 are respectively fixedly sleeved with limiting rings 14 on both sides of the insulating tape 10, which can restrict the movement of the insulating tape 10 along the axial direction of the rotating roller 5, tension roller 9 and guide roller 11, thereby further preventing the insulating tape 10 from deviating.

[0030] Furthermore, a long strip of bristles 15 is fixedly provided on the inner sidewall of the elongated hole 1a, and the long strip of bristles 15 cleans the outer side of the insulating tape 10. By using the above-mentioned long strip of bristles 15, the dust on the surface of the insulating tape 10 can be automatically cleaned when the insulating tape 10 moves, so as to keep the surface of the insulating tape 10 clean and hygienic.

[0031] Furthermore, a pair of protective covers 16 are fixedly installed on the top of the tabletop 1, respectively covering the two elongated holes 1a. The protective covers 16 have an opening on the side near the aluminum plate 4 for the insulating belt to pass through. The protective covers 16 prevent workers' fingers from getting stuck in the gap between the side wall of the elongated hole 1a and the insulating belt, thereby effectively ensuring the safety of workers.

[0032] The working principle of this embodiment:

[0033] When printing on shoe uppers, first place the shoe upper and printing template on the insulating tape 10 above the aluminum plate 4, and manually move them under the pressure plate of the high-frequency printing equipment 3. At this time, the insulating tape 10 is stretched into an inverted U-shape by the tension roller 9, rotating roller 5, guide roller 11, and transition roller 13. Furthermore, the rotating roller 5 remains stationary due to self-locking when the worm gear reducer motor 6 is stopped. Therefore, moving or adjusting the shoe upper position at this time will not easily cause the insulating tape 10 to shift or move randomly. Then, after the shoe upper and printing template are adjusted to the appropriate positions, the high-frequency printing equipment 3 can be turned on. The shoe upper undergoes printing processing. Finally, after the shoe upper printing processing is completed, the worm gear reducer motor 6 is turned on to drive the rotating roller 5 to rotate, which allows the insulating tape 10 to move relative to the aluminum plate 4. This not only replaces the position of the insulating tape 10 that has just been heated and pressed with the position that has not been heated and pressed, but also quickly brings out the printing template with a higher temperature and the shoe upper that has been printed from the bottom of the pressure plate of the high-frequency printing equipment 3. This effectively extends the life of the insulating tape 10 and also simplifies the unloading process, avoiding burn accidents caused by workers rushing to remove the printing template and the inclined surface.
