Description

Technical Field

[0001] The utility model relates to the technical field of screen printing machines, and particularly relates to a self-locking device in a flat screen printing machine. Background Art

[0002] A screen printing machine is a machine for printing characters and images, and is a general term for machines or devices used for producing printed products. The screen printing machine belongs to a representative printing device in the hole plate printing machine. The materials for making the screen can be nylon wire, copper wire, steel wire or stainless steel wire in addition to real silk.

[0003] When most of the existing flat screen printing machines are working, they often need to cooperate with a screen. Although most of the existing screens can be tightened and positioned by multi-point bolts in the screen printing machine, when some of the existing screens are positioned by bolts, there is a deviation when the first bolt abuts against the screen, resulting in the deviation of the printing factors on the screen. At the same time, adjusting and positioning the multi-point bolts not only makes the operation cumbersome and complex, but also causes disadvantages such as the overall operation efficiency of the screen printing machine. Content of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and can solve the problems put forward in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A self-locking device in a flat screen printing machine, including a screen printing machine, a screen body is arranged inside the screen printing machine, a wire guiding support plate is fixedly installed inside the screen printing machine, a wire guiding groove is opened inside the wire guiding support plate, a self-locking ring is welded on the surface of the screen body, a self-locking column is slidably installed inside the self-locking ring, a first spring is slidably sleeved on the surface of the self-locking column, and two ends of the first spring are respectively fixedly installed on the surface of the self-locking column and inside the positioning groove, and a guiding support plate is rotatably installed inside the screen printing machine.

[0006] Preferably, the outer shape of the self-locking ring is arc-shaped, and a positioning groove is opened inside the self-locking ring.

[0007] Preferably, a through groove is opened inside the screen printing machine, and the surface of the self-locking column is slidably installed on the inner wall of the through groove.

[0008] Preferably, both the upper and lower ends of the self-locking column are conical surfaces.

[0009] Preferably, the shape of the wire guiding groove is inclined, and the shape of the surface of the wire guiding support plate is also inclined.

[0010] Preferably, the guiding support plate is located above the self-locking column, and an extension groove is opened on the surface of the guiding support plate.

[0011] Preferably, a guiding column is slidably installed inside the guiding support plate, and a second spring is slidably sleeved on the surface of the guiding column. The two ends of the second spring are respectively fixedly installed on the surface of the guiding column and the inside of the guiding support plate.

[0012] Preferably, a first positioning groove and a second positioning groove are formed inside the screen printing machine, and the lower end of the guiding column is slidably installed on the inner wall of the first positioning groove.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] (1). In the self-locking device of the flat screen printing machine, when more stable self-locking of the screen body is required, the operator only needs to rotate the guiding support plate so that the extension groove on the guiding support plate is misaligned with the self-locking column. Therefore, the guiding support plate is realized to push the self-locking column to continuously descend into the inner side of the self-locking ring to form self-locking for the screen body. Therefore, it ensures that the screen body has multiple self-locking effects in the screen printing machine, improves the tediousness of the traditional multi-point bolt positioning operation between the screen body and the screen printing machine, and improves the effect of convenient self-locking when the screen body and the screen printing machine are used in cooperation. It not only ensures the anti-deviation effect when printing characters and images, but also ensures that the screen body and the screen printing machine have a simple self-locking operation.

[0015] (2). In the self-locking device of the flat screen printing machine, when the guiding support plate needs to be adjusted, the operator only needs to control the guiding column to slide out of the inner wall of the first positioning groove. Until the guiding column reaches the second positioning groove, the guiding column is pushed into the inner wall of the second positioning groove to form positioning through the elastic performance of the compressed second spring. Furthermore, it ensures that the guiding support plate has a convenient positioning effect after adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Please refer to Figures 1-5 , the present invention provides a technical solution: a self-locking device in a flat screen printing machine, including a screen printing machine 1. A screen body 2 is arranged inside the screen printing machine 1. A wire guiding support plate 3 is fixedly installed inside the screen printing machine 1. A wire guiding groove 4 is opened inside the wire guiding support plate 3. The shape of the wire guiding groove 4 is inclined, and the surface shape of the wire guiding support plate 3 is also inclined. Through the inclined shape of the wire guiding support plate 3 itself and the inclined surface of the wire guiding groove 4 on the wire guiding support plate 3, it ensures that the screen body 2 has a convenient guiding and sliding effect inside the screen printing machine 1, and reduces the drawback that the screen body 2 cannot form quick positioning inside the screen printing machine 1 and causes overall deviation.

[0028] Furthermore, a self-locking ring 5 is welded on the surface of the screen body 2, the outer side of the self-locking ring 5 is in an arc shape, a positioning groove 6 is provided on the inner side of the self-locking ring 5, a self-locking column 7 is slidably installed on the inner wall of the positioning groove 6 on the self-locking ring 5, a first spring 8 is slidably sleeved on the surface of the self-locking column 7, and both ends of the first spring 8 are respectively fixedly installed on the surface of the self-locking column 7 and the inner side of the positioning groove 6, a through groove 9 is provided on the inner side of the screen printing machine 1, the surface of the self-locking column 7 is slidably installed on the inner wall of the through groove 9, the upper and lower ends of the self-locking column 7 are both conical surfaces, and a guide support plate 10 is rotatably installed on the inner side of the screen printing machine 1, the guide support plate 10 is located above the self-locking column 7, and an extension groove 11 is provided on the surface of the guide support plate 10.

[0029] Specifically, when the screen body 2 is docked on the inner side of the screen printing machine 1, the screen body 2 will push the conical surface self-locking pin 7 through its own arc-shaped self-locking ring 5, so that the self-locking pin 7 enters the inner wall of the extension groove 11 on the guide support plate 10, until the self-locking pin 7 is aligned with the positioning groove 6. At this time, the elastic performance of the compressed first spring 8 pushes the arc surface of the self-locking pin 7 to the inner side of the self-locking ring 5, and the straight surface of the self-locking pin 7 will not reach the inner side of the positioning groove 6 on the self-locking ring 5, so that the screen body 2 is formed in a pre-positioned self-locking state on the inner side of the screen printing machine 1. When the screen body 2 needs to be self-locked more stably, it only needs to be operated The author rotates the guide support plate 10 to cause the extension groove 11 on the guide support plate 10 to be misaligned with the self-locking column 7, so that the guide support plate 10 pushes the self-locking column 7 to continuously descend to the inner side of the self-locking ring 5 to form a self-locking on the screen body 2, thereby ensuring that the screen body 2 has multiple self-locking effects in the screen printing machine 1, improving the cumbersomeness of the traditional multi-point bolt positioning operation between the screen body 2 and the screen printing machine 1, and improving the convenient self-locking effect when the screen body 2 and the screen printing machine 1 are used in conjunction, which not only ensures the anti-deviation effect when printing text and images, but also ensures a simple self-locking operation between the screen body 2 and the screen printing machine 1.

[0030] Furthermore, a guide column 12 is slidably installed on the inner side of the guide support plate 10, and a second spring 13 is slidably sleeved on the surface of the guide column 12. Both ends of the second spring 13 are respectively fixedly installed on the surface of the guide column 12 and the inner side of the guide support plate 10. A first positioning groove 14 and a second positioning groove 15 are opened on the inner side of the screen printing machine 1, and the lower end of the guide column 12 is slidably installed on the inner wall of the first positioning groove 14.

[0031] Specifically, when the guide support plate 10 needs to be adjusted, the operator only needs to control the guide column 12 to slide out from the inner wall of the first positioning groove 14 until the guide column 12 reaches the second positioning groove 15. Then, the guide column 12 is pushed into the inner wall of the second positioning groove 15 by the elastic force of the compressed second spring 13 to form a positioning, thereby ensuring that the guide support plate 10 has a convenient positioning effect after adjustment.

[0032] Working principle: A self-locking device in a flat screen printing machine. When the screen body 2 is docked on the inner side of the screen printing machine 1, the screen body 2 will push the conical self-locking pin 7 through its own arc-shaped self-locking ring 5, and then the self-locking pin 7 will enter the inner wall of the extension groove 11 on the guide support plate 10, until the self-locking pin 7 is aligned with the positioning groove 6. At this time, the elastic performance of the compressed first spring 8 pushes the arc surface of the self-locking pin 7 to the inner side of the self-locking ring 5, and the straight surface of the self-locking pin 7 will not reach the inner side of the positioning groove 6 on the self-locking ring 5, so that the screen body 2 is formed in a pre-positioned self-locking state on the inner side of the screen printing machine 1. When the screen body 2 needs to be self-locked more stably, the operator only needs to rotate the guide support plate 10 to make the extension groove 11 on the guide support plate 10 misaligned with the self-locking pin 7, so that the guide support plate 10 pushes the self-locking pin 7 to continue to descend to the inner side of the self-locking ring 5 to self-lock the screen body 2.

[0033] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
