[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-4 One embodiment of this utility model provides a screen printing frame for shoe processing, comprising a screen printing frame 1, a mounting groove, and a fixing component.

[0025] When it is necessary to print patterns, numbers or logos on the surface of shoes, place the screen printing frame 1 on the surface of the shoe material, and then use a squeegee to spread the ink evenly. The ink will adhere to the shoe surface through the pattern on the printing plate, thus achieving the printing of the shoes (this is existing technology and will not be described in detail here).

[0026] The mounting slot is located at the top of the screen printing frame 1, and the inner cavity of the mounting slot is connected to the inner wall of the screen printing frame 1. A fixing strip 2 is detachably installed in the inner cavity of the mounting slot. A winding roller 9 is installed inside the fixing strip 2 by means of a torsion spring. The outer wall of the winding roller 9 is wound with a printing screen body 3 for printing. When it is necessary to print numbers, patterns, or logos on the surface of the shoes, the printing screen body 3 with the same pattern as the desired printing pattern is selected, and then the fixing strip 2 is placed in the inner cavity of the mounting slot.

[0027] The inner cavity of the storage chamber is symmetrically fixed with mounting tubes 7 on both sides. The two ends of the take-up roller 9 are fixedly mounted with rotating shafts. The end of the rotating shaft away from the take-up roller 9 extends into the inner cavity of the mounting tube 7, and a torsion spring is fixedly sleeved on the outer wall of the rotating shaft. One end of the torsion spring is fixedly connected to the inner wall of the mounting tube 7. When the take-up roller 9 rotates along the tangential direction of the movement of the screen body 3, the torsion spring is compressed. At this time, the torsion spring stores its own elastic potential energy. When the inner wall of the free end of the screen frame 1 of the screen body 3 is separated, the torsion spring releases the stored elastic potential energy and converts the elastic potential energy into its own rotational kinetic energy, so that the screen body 3 can be neatly rolled up outside the take-up roller 9.

[0028] The fixing strip 2 has a storage chamber adapted to the take-up roller 9 inside. One side of the fixing strip 2 has a connecting groove that communicates with the storage chamber. When the fixing strip 2 is placed in the inner cavity of the mounting groove, the open end of the connecting groove is located in the inner cavity of the screen printing frame 1. Then, the free end of the screen printing body 3 is pulled. At this time, under the pull of the screen printing body 3, the take-up roller 9 rotates along the tangent direction to the moving end of the screen printing body 3, so that the free end of the screen printing body 3 moves continuously towards the inner wall of the screen printing frame 1 away from the mounting groove until the free end of the screen printing body 3 is in contact with the inner wall of the screen printing frame 1 away from the mounting groove. Then, the screen printing frame 1 is placed on top of the shoe printing surface, and the outer wall of the screen printing body 3 is in contact with the shoe printing surface. Then, the ink is applied to the outside of the screen printing body 3, and the ink is spread evenly with a squeegee to achieve printing on the shoe printing surface.

[0029] When the desired printed pattern needs to be changed, the free end of the printing screen body 3 is detached from the inner wall of the printing frame 1. At this time, the torsion spring converts its own elastic potential energy into the kinetic energy of the winding roller 9 until the free end of the printing screen body 3 is reset. Then, the fixing strip 2 is taken out from the mounting groove, and the printing screen body 3 with the same desired printed pattern is placed in the mounting groove through the fixing strip 2. The free end of the printing screen body 3 is pulled until the free end of the printing screen body 3 and the inner wall of the printing frame 1 are attached. This allows the printing screen body 3 with different patterns to be replaced, reducing the production cost and cycle of shoes.

[0030] A fixing component is set outside the screen printing frame 1. The fixing component can fix the free end of the screen printing body 3. When the free end of the screen printing body 3 is attached to the inner wall away from the mounting groove, the fixing component can be used to fix the free end of the screen printing body 3. This prevents the free end from resetting when the screen printing body 3 is used to print on the shoe surface, and improves the stability of the screen printing body 3 when printing shoe surface patterns.

[0031] Positioning blocks 5 are fixedly installed at both ends of the fixing strip 2. The inner cavity of the mounting groove has receiving grooves on both sides that are compatible with the positioning blocks 5. When the fixing strip 2 is placed into the inner cavity of the mounting groove, the positioning blocks 5 at both ends enter the inner cavities of the two receiving grooves until the bottom of the positioning blocks 5 fits into the bottom of the inner cavity of the receiving groove.

[0032] The top of the positioning block 5 has a through hole that communicates with its bottom. A fixing bolt 4 is slidably installed in the inner cavity of the through hole. The bottom of the inner cavity of the receiving groove has a threaded hole that matches the fixing bolt 4. When the bottom of the positioning block 5 and the bottom of the inner cavity of the receiving groove are in contact, the middle of the opening end of the through hole and the middle of the opening end of the threaded hole are on the same horizontal line. Then, the small end of the fixing bolt 4 is passed through the through hole and enters the inner cavity of the threaded hole. Then, the large end of the fixing bolt 4 is continuously rotated. When the small end of the fixing bolt 4 and the bottom of the inner cavity of the threaded hole are in contact, the large end of the fixing bolt 4 is in contact with the top of the positioning block 5. This achieves the purpose of limiting the fixing strip 2 by fixing bolt 4 and preventing the fixing strip 2 from detaching from the inside of the mounting groove.

[0033] The printing screen body 3 is made of polyester material, which can increase its plastic deformation ability and its own strength. It can be neatly rolled up on the outside of the take-up roller 9, which improves the convenience of printing screen body 3 during take-up and take-up and extends its service life.

[0034] The fixing component includes a mounting strip 8, one side of which is fixedly connected to the free end of the screen printing body 3. The inner wall of the screen printing frame 1 away from the mounting groove has an adapter groove that matches the mounting strip 8. The top side of the screen printing frame 1 away from the mounting groove has multiple through holes communicating with the inner cavity of the adapter groove. Fastening bolts 6 are detachably installed in the inner cavity of the through holes. The outer wall of the mounting strip 8 has a threaded groove that matches the fastening bolts 6. Pulling the mounting strip 8 moves it closer to the adapter groove. Move the mounting strip 8 until it is inside the fitting groove, until the middle of the opening end of the multiple through holes and the middle of the opening end of the threaded groove are on the same horizontal line. Then insert the small end of the fastening bolt 6 into the inner cavity of the through hole until the small end enters the inner cavity of the threaded groove. Then continue to rotate the small end of the fastening bolt 6. When the small end of the fastening bolt 6 is in contact with the bottom of the inner cavity of the threaded groove, the large end of the fastening bolt 6 is in contact with the top of the screen printing frame 1, thus fixing the mounting strip 8.

[0035] When the free end of the printing screen body 3 needs to be reset, rotate the large end of the fastening bolt 6 in the opposite direction until the small end of the fastening bolt 6 is disengaged from the inside of the thread groove. Then, disengage the small end of the fastening bolt 6 from the inside of the through hole. Under the action of the torsion spring, the printing screen body 3 can be neatly rolled up to the outside of the take-up roller 9.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
