[0014] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0015] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0016] Example 1: This embodiment provides a clamping and fixing structure for a screen scraper, including: Outer shell 1, with a storage chamber inside; The clamping assembly includes a fixed base 2, a connecting base 3, and an abutting rod 4. The fixed base 2 is mounted on the outer shell 1 for placing the wire mesh scraper. The connecting base 3 is cylindrical and can be rotatably disposed inside the outer shell 1. The abutting rod 4 can be axially moved through the fixed base 2 and is threadedly connected to the inside of the connecting base 3. A transmission assembly is installed inside the housing 1 to drive the connecting seat 3 to rotate circumferentially; The control and drive components are mounted on the outside of the housing 1 to control the operation of the transmission components.

[0017] In this technical solution, the two ends of the screen squeegee are installed on the printing equipment through two clamping and fixing structures. A storage slot is provided in the fixing base 2, and the end of the abutment rod 4 extends into the storage slot through the fixing base 2. The end of the screen squeegee is installed in the storage slot. Then, the transmission component is controlled by the control component to drive the connecting base 3 to rotate. The rotation of the connecting base 3 changes the amount of threaded connection between the abutment rod 4 and the bracket of the connecting base 3, thereby causing the abutment rod 4 to move axially and extend to abut the screen squeegee, pressing the screen squeegee tightly against the fixing base 2, thus achieving the clamping and fixing of the screen squeegee.

[0018] The above structural design enables the screen squeegee to be installed and fixed on the printing machine. At the same time, the screen squeegee is easy to disassemble and assemble, convenient to maintain, and highly practical.

[0019] Furthermore, the transmission assembly includes a worm gear 5 and a worm 6. The worm gear 5 is installed inside the housing 1 and connected to the connecting seat 3; the worm 6 is rotatably installed on the housing 1 and meshes with the worm gear 5; the control assembly is used to control the rotation of the worm 6. Through this structural design, the control assembly drives the worm 6 to rotate, which in turn drives the worm gear 5 to rotate, causing the connecting seat 3 to rotate together, thereby enabling the abutment rod 4 to move axially and achieve the clamping and fixing of the wire mesh scraper.

[0020] Furthermore, the connecting seat 3 is also provided with a positioning block 7, and the housing 1 is provided with a positioning groove 8 that is adapted to the structure of the positioning block 7. Through this structural design, the connecting seat 3 is positioned within the housing 1, which facilitates the installation and fixation of the connecting seat 3 within the housing 1 and is highly practical.

[0021] Furthermore, the abutment rod 4 has a guide strip 9, and the fixing seat 2 is provided with a guide groove 10 that is adapted to the structure of the guide strip 9. Through this structural design, the abutment rod 4 is prevented from deflecting by the adapted connection of the guide strip 9 and the guide groove 10, ensuring that the abutment rod 4 is firmly pressed against the scraper.

[0022] Example 2: This embodiment provides a clamping and fixing structure for a wire mesh scraper, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0023] Furthermore, the worm gear 6 is provided with an extension 11 and a retaining strip 12; The control assembly includes a knob 13 and a locking nut 14. The knob 13 is sleeved on the worm gear 6, and the extension 11 passes through the knob 13. The locking nut 14 is threaded onto the end of the extension 11. The knob 13 has a slot 15 inside, and the slot 12 is adapted to and connected to the slot 15.

[0024] Through this structural design, the matching connection of the clip 12 and the slot 15 allows the operator to manually rotate the knob 13 to control the rotation of the worm gear 6. Furthermore, by observing the contact between the abutment rod 4 and the wire mesh scraper, it is possible to better determine whether the wire mesh scraper is securely connected, making it highly practical.

[0025] Furthermore, the control components also include: The telescopic spring 16 is sleeved on the extension 11 and axially abuts against the worm gear 6 and the knob 13.

[0026] A groove is provided on the end face of the knob 13 near the worm 6. The knob 13 is rotatably fitted onto the worm 6 through the groove. The length of the extension 11 is designed to allow the knob 13 to move axially. The telescopic spring 16 abuts axially between the worm 6 and the knob 13, pressing the knob 13 against the locking nut 14.

[0027] In this technical solution, the operator can push the knob 13 to move on the extension 11. When the knob 13 moves closer to the worm gear 6, the locking strip 12 engages with the slot 15, and the telescopic spring 16 is compressed. At this time, the operator can rotate the knob 13 to drive the worm gear 6 to rotate. When the operator releases the knob 13, the telescopic spring 16 returns to its original position, pushing the knob 13 closer to the locking nut 14. At this time, although the knob 13 can rotate, the locking strip 12 and the slot 15 do not engage, and the worm gear 6 will not rotate with the knob 13. Through this structural design, the knob 13 achieves the function of preventing accidental operation, avoiding the abutting rod 4 from moving away from the wire mesh scraper due to accidental operation of the knob 13, effectively preventing the wire mesh scraper from loosening, and has high practicality.

[0028] Furthermore, the surface of the knob 13 is provided with anti-slip grooves 17. The anti-slip grooves 17 make it easier for workers to grip the knob 13, allowing them to turn the knob 13 with less effort, thus improving its practicality.

[0029] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
