Description

Technical Field

[0001] This utility model relates to the field of net stretching machine technology, and more specifically, to a glue application device for a net stretching machine. Background Technology

[0002] LCD screens are a type of flat panel display used for television and computer screens. After the screen is manufactured, some parameter information needs to be screen-printed on the outer casing, usually through screen printing. The screen stretching machine is an indispensable piece of equipment for making screen printing plates. The principle is to stretch the screen to the frame with a certain tension. In order for the screen to be firmly fixed to the frame, adhesive needs to be applied to the frame.

[0003] A search revealed that utility model patent CN214717896U discloses a gluing device for a mesh stretching machine, including a work frame and a worktable fixed to its upper surface. A rotating plate is rotatably mounted on the worktable, and a propulsion cylinder is fixed to the upper surface of the rotating plate. One end of a propulsion block is fixed to the end of the piston rod of the propulsion cylinder, and a gluing plate is elastically mounted on the other end of the propulsion block. A gluing roller is rotatably mounted on the gluing plate facing the surface of the worktable, and a gluing port is opened on the surface of the gluing plate facing the worktable. The gluing port is connected to a gluing box fixed to the upper surface of the rotating plate through a gluing pipe. The gluing pipe is also connected to an air pump for dispensing the glue stored in the gluing box out of the gluing port. A limiting component is also provided on the upper surface of the worktable for limiting the displacement trajectory of the gluing plate and clamping the mesh frame, which can automatically complete the gluing work of the mesh frame instead of manual labor. However, the aforementioned patents have the following shortcomings: they are not convenient for adjusting the height of the gluing mechanism, making it inconvenient to apply glue to mesh frames of different thicknesses, resulting in poor practicality; and they are also inconvenient for cleaning the glued surface of the mesh frame, affecting the quality of the glued and fixed wire mesh. Therefore, we propose a gluing device for a mesh stretching machine. Utility Model Content

[0030] For details, please refer to Figure 2 The side of the transverse block 7 fits into the inner wall of the transverse groove 5.

[0031] In this embodiment, the inner wall of the transverse groove 5 is used to limit the transverse block 7, so that the transverse block 7 can only move along the axial direction of the transverse bidirectional lead screw 6.

[0032] For details, please refer to Figure 2 The side of the longitudinal moving block 12 fits against the inner wall of the longitudinal groove 10.

[0033] In this embodiment, the longitudinal groove 10 is used to limit the longitudinal moving block 12, so that the longitudinal moving block 12 can only move along the axial direction of the longitudinal bidirectional lead screw 11.

[0034] For details, please refer to Figure 1 The front of the ash storage box 32 is hinged with a sealing door 33.

[0035] In this embodiment, the dust collected in the ash storage box 32 is cleaned by opening the sealing door 33.

[0036] Working principle: In use, first place the mesh frame in the inner cavity of the working groove 2, and start the first motor 9 and the second motor 14 respectively. The first motor 9 drives the transverse bidirectional lead screw 6 to rotate. Through the threaded engagement between the transverse bidirectional lead screw 6 and the two transverse moving blocks 7, the two transverse clamping plates 8 move closer to each other. The two transverse clamping plates 8 clamp and fix the two sides of the mesh frame. The second motor 14 drives the longitudinal bidirectional lead screw 11 to rotate. Through the threaded engagement between the longitudinal bidirectional lead screw 11 and the two longitudinal moving blocks 12, the two longitudinal clamping plates 11 move closer to each other. The plates 13 are brought close together, and the front and rear of the wire mesh frame are clamped and fixed using two longitudinal clamping plates 13. Then, the powerful exhaust fan 37 is started to draw air from the inner cavity of the ash storage box 32. The negative pressure inside the ash storage box 32 causes the telescopic hose 35 and the dust suction hood 36 to generate suction. The dust suction hood 36 is held to adsorb the glued surface of the wire mesh frame, thereby sucking the dust on the glued surface of the wire mesh frame into the inner cavity of the ash storage box 32. The dust is trapped and collected in the inner cavity of the ash storage box 32 by the filter screen 34. Then, the multi-stage electric push rod 21 is started to drive the trajectory. The limiting wheel 25 approaches the longitudinal clamping plate 13 or the transverse clamping plate 8, compressing the air spring 23 to ensure a tight fit between the trajectory limiting wheel 25 and the inner surfaces of the longitudinal clamping plate 13 or the transverse clamping plate 8. Additionally, the electric telescopic rod 16 is activated, moving the lifting plate 17, rotating disk 19, glue spray box 26, and scraper 28 up and down. This positions the bottom surface of the scraper 28 a certain distance above the glue-coated surface of the mesh frame, allowing the trajectory limiting wheel 25 to contact the inner surfaces of the longitudinal clamping plate 13 and the transverse clamping plate 8. Finally, the glue pump 30 is activated to pump the glue storage box 2... The adhesive in 9 is drawn into the glue spray box 26, and the adhesive in the glue spray box 26 falls from the glue spray hole 27 onto the glue coating surface of the mesh frame. In addition, the third motor 18 is started to drive the rotating disk 19, mounting base 20, multi-stage electric push rod 21, air rod 23, U-shaped frame 24, track limit wheel 25, glue spray box 26 and scraper 28 to rotate synchronously. The movement of the glue spray box 26 is limited by the contact of the track limit wheel 25 on the inner side of the longitudinal clamping plate 13 or the transverse clamping plate 8. At the same time, the scraper 28 is used to spread the adhesive on the mesh frame evenly.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
