Description

Technical Field

[0001] The invention relates to the technical field of laminating screen plates, and in particular to a composite laminating screen plate mechanism. Background Art

[0002] The laminating screen mechanism is usually a mechanism used on a screen laminating machine, which is used to absorb the film body and then bring it close to the laminating object for laminating. In the Chinese patent with the announcement number CN215283861U, an automatic screen laminating machine is disclosed, including a frame, a flap assembly, a horizontal laminating assembly, and a control unit. The flap assembly is arranged at one end of the frame and can rotate in the frame, and the horizontal laminating assembly is arranged at the other end of the frame and can move to the bottom of the flap assembly during operation. The control unit is electrically connected to the flap assembly and the horizontal laminating assembly respectively. The mechanized laminating operation is adopted to replace the manual laminating by the staff, which overcomes the problem of poor laminating quality caused by the staff's mistakes such as uneven force and hand shaking during the operation, which is conducive to ensuring the quality and efficiency of laminating, and is conducive to improving the benefits of the enterprise; and the mechanized laminating operation can work for a long time, which is conducive to reducing labor costs, and at the same time avoids the problem of safety hazards caused by fatigue of the staff during the laminating process, which is conducive to improving the safety factor.

[0003] However, the above-mentioned comparative documents disclosed and the mesh mechanism currently on the market are composed of a single outer frame and a layer of mesh, which are relatively large in size. The roller is installed inside the mesh, which is not convenient for disassembly and replacement, and the use of the roller cannot be observed more directly. At the same time, when a fault occurs on the surface of the pressure roller, it cannot be discovered in time. When there are protrusions attached to the surface of the pressure roller, contact with the film body may cause the film body to rupture, affecting the quality. When there are depressions on the surface of the pressure roller, it may cause local pressing to be insufficient and bubbles are likely to appear. In view of this, the present application is proposed. Summary of the invention

[0004] To this end, the present invention provides a composite laminating screen plate mechanism to solve the above-mentioned problems that the pressing roller is inconvenient to replace and repair, and the failure of the pressing roller cannot be quickly identified.

[0005] The present invention provides the following technical solution: a composite laminating screen mechanism, comprising: An upper plate, a lower plate and a sealing member are provided, wherein the lower plate is used for contacting and adsorbing with the membrane body, and the sealing member is arranged between the upper plate and the lower plate to form a seal between the upper plate and the lower plate, and a vacuum cavity is formed between the sealing member and the lower plate; The upper mesh plate, the lower mesh plate and the sealing member are jointly provided with screw mounting holes which penetrate upward and downward. In actual use, the upper mesh plate, the lower mesh plate and the sealing member can be assembled by drilling screws into the screw mounting holes to form a composite integrated structure. The upper mesh plate is provided with a vacuum channel. One end of the bottom of the vacuum channel penetrates the sealing member and extends to the inner cavity of the lower mesh plate to communicate with the vacuum cavity. A composite structure is adopted to adsorb the membrane body, and then it is fitted through other related equipment. Specifically, the upper part is the upper mesh plate, which cooperates with the sealing member below to form a fully sealed mesh plate to prevent air flow loss and form an adsorption cavity, i.e., a vacuum cavity, at the bottom, so that the product can be positioned on the lower mesh plate. The middle part is the sealing member, which is used to form a seal and prevent air leakage in the outer frames of the upper and lower mesh plates. The lower part is the lower mesh plate as a graphic mesh plate, which plays the function of adsorbing the product for positioning. Air avoidance is performed according to the product graphic, and the graphic is sealed outside to firmly position the product on the lower mesh plate.

[0006] As a preferred solution of the present invention, rotating and telescopic control parts are fixedly installed on the front and rear side walls of the upper mesh plate and the lower mesh plate, and the control ends of the two rotating and telescopic control parts are commonly connected to a detachable pressure roller. The position of the detachable pressure roller can be flexibly adjusted by rotating the telescopic control part to achieve different technical effects. The detachable pressure roller moves to the bottom of the lower mesh plate and then moves left and right, which can be used to press and fit the membrane body. The detachable pressure roller moves to the side of the elastic scraping mechanism and then applies a certain pressure to the elastic scraping mechanism and then rotates, which can be used to scrape protrusions on the surface of the pressure roller. After the detachable pressure roller moves to between the curtain and the direct light, the pressure roller continues to rotate, which can be used to detect depressions on the surface of the pressure roller.

[0007] As a preferred solution of the present invention, the rotating telescopic control component includes a mounting seat that is simultaneously installed on the side walls of the upper mesh plate and the lower mesh plate by screws, a rotating seat is arranged on the outer wall of the mounting seat, and an electrically driven multi-section telescopic rod is fixedly arranged on the rotating seat, and the telescopic end can be extended to a position of 10-50cm on the right side of the mesh plate at most. The electrically driven multi-section telescopic rod is electrically driven and has a large telescopic space, so that the position of the pressure roller can be flexibly adjusted in a larger area to adapt to different usage requirements. The end of the detachable pressure roller is inserted into the telescopic end of the electrically driven multi-section telescopic rod, and the position of the pressure roller at the end is moved by the telescopic control of the electrically driven multi-section telescopic rod.

[0008] As a preferred solution of the present invention, a rotation adjustment motor is also installed on the mounting seat on one side through a motor bracket, and the output shaft of the rotation adjustment motor is connected to the central axis of the rotating seat, which is used to control the swing of the electrically driven multi-section telescopic rod, and then control the movement of the detachable pressure roller. The rotating seat is rotationally adjusted by the rotation adjustment motor, and the pressure roller can be flexibly moved to different positions in coordination with the telescopic effect of the electrically driven multi-section telescopic rod.

[0009] As a preferred solution of the present invention, the detachable pressing roller consists of a pressing roller and a connecting seat rotatably arranged at both ends of the pressing roller. A through hole is provided on the connecting seat, and the telescopic end of the electrically driven multi-section telescopic rod is penetrated through the through hole. The pressing roller can stably rotate on the connecting seat, and after being pressed onto the film body, it can naturally rotate with the movement of the connecting seat to press the film body, thereby realizing the film body bonding function.

[0010] As a preferred solution of the present invention, the end of the electrically driven multi-section telescopic rod is arranged as a threaded section, and a fitting piece is fixed to the threaded section on one side close to the main body of the electrically driven multi-section telescopic rod, for preventing the pressure roller from continuing to move inward. After the pressure roller penetrates the electrically driven multi-section telescopic rod and fits with the fitting piece, a fixing nut is screwed into the threaded section to install the detachable pressure roller on the control end of the rotary telescopic control component. This threaded fixing method can facilitate the quick and easy loading and unloading of the detachable pressure roller, so that when a fault of the detachable pressure roller is found, it can be quickly disassembled, replaced or repaired, thereby greatly improving work efficiency.

[0011] As a preferred solution of the present invention, an elastic scraping mechanism is fixedly provided on the front and rear side walls of the upper mesh plate for scraping off protrusions adhered to the pressure roller, and a material receiving box is fixedly provided on the side wall of the lower mesh plate. The material receiving box is located below the elastic scraping mechanism and is used to catch the protrusions scraped from the pressure roller by the elastic scraping mechanism when they fall down, thereby preventing solid particles from entering the processing space below.

[0012] As a preferred solution of the present invention, the elastic scraping mechanism is composed of two elastic telescopic rods respectively fixed to the front and rear side walls of the upper screen, the telescopic ends of the two elastic telescopic rods are connected with mounting plates, and a scraping wire is fixedly arranged between the two mounting plates. The setting of the elastic telescopic rod allows the pressure roller to have a certain buffer space when contacting the scraping wire, so as to avoid the pressure roller from breaking the scraping wire in the absence of a buffer structure. At the same time, the elastic structure can provide a certain pressure between the pressure roller and the scraping wire, so that the scraping wire fits more fully with the surface of the pressure roller, and the protrusions on the surface of the pressure roller can be better scraped when the pressure roller rotates. A vibration sensor can also be installed on the scraping wire. When the surface of the pressure roller is smooth, the scraping wire will not vibrate significantly when contacting the pressure roller. When scraping protruding particles that are difficult to remove, the scraping wire will be pulled by the protrusions and detach after being pulled to a certain extent. At this time, a significant vibration will occur. The vibration is detected by the vibration sensor, and a threshold value and an external reminder are set for the vibration sensor. When the vibration amplitude exceeds the threshold value, the reminder is controlled to sound to remind the staff to manually clean the pressure roller or replace the pressure roller.

[0013] As a preferred solution of the present invention, a depression detection component is also fixedly arranged on the top of the screen, which is used to project each cross section of the pressure roller onto the screen and then shoot and enlarge the display to identify the depression on the surface of the pressure roller. The depression detection component includes a projection display screen fixed to one side of the top of the screen, and a direct light and a projection frame installed on the back of the projection display screen through a fixed connecting rod. A screen is arranged in the projection frame, and the pressure roller moves between the screen and the direct light. The direct light emits direct light upwards. The black shadow projected by the pressure roller on the screen is rectangular in shape. As the pressure roller rotates continuously, The projection arc surface of the pressure roller is constantly switched, and the concave part is projected on the screen to form a rectangular concave notch. A monitoring box is fixedly arranged on the top of the projection frame, and a mounting strip is built into the monitoring box. A number of evenly distributed cameras are fixedly installed on the bottom of the mounting strip to shoot the projection screen below and transmit the video to the projection display screen in real time. The staff nearby only need to observe the image on the projection display screen to see whether the projected rectangular shape changes. Whether the rectangle appears concave or convex, it indicates that the pressure roller is defective and can be repaired or replaced at this time.

[0014] As a preferred solution of the present invention, the detachable pressing roller moves to the bottom of the lower mesh plate and then moves left and right, and can be used to press and fit the film body; The detachable pressure roller moves to the side of the elastic scraping mechanism, applies a certain pressure to the elastic scraping mechanism, and then rotates, which can be used to scrape off protrusions on the surface of the pressure roller; After the detachable pressing roller is moved between the curtain and the direct-illumination lamp, the pressing roller continues to rotate, and can be used to detect the concave parts on the surface of the pressing roller.

[0015] The beneficial effects of the present invention are as follows: 1. The upper part of the present invention is an upper mesh plate, which cooperates with the sealing member below to form a fully sealed mesh plate, which can prevent air flow loss and form an adsorption cavity below, that is, a vacuum cavity, so that the product can be positioned on the lower mesh plate. The middle part is a sealing member, which is used to form a leak-proof seal in the outer frames of the upper and lower mesh plates. The lower part is a lower mesh plate, which plays the function of adsorbing and positioning the product. Air is avoided according to the product graphics, and the graphics are sealed outside to firmly position the product on the lower mesh plate. The negative pressure inside the vacuum cavity is used to adsorb and fix the film body, and then it can be bonded. It can be applied to the bonding of soft film to soft film and soft film to hard board in various industries. The pressing roller used for bonding is installed externally, and the use of the roller can be observed in real time. At the same time, the roller can be replaced quickly and conveniently to improve production efficiency.

[0016] 2. The detachable pressure roller of the present invention can be moved to various positions according to needs under the control of the rotating and telescopic control part. After moving to the bottom of the lower mesh plate, it can be moved left and right to press and fit the membrane body. After moving to the side of the elastic scraping mechanism, a certain pressure is applied to the elastic scraping mechanism and then rotated to scrape off the protrusions on the surface of the pressure roller. After moving to between the curtain and the direct light, the pressure roller continues to rotate to detect the depressions on the surface of the pressure roller. BRIEF DESCRIPTION OF THE DRAWINGS

The detachable pressure roller 5 moves to the side of the elastic scraping mechanism 6 and then applies a certain pressure to the elastic scraping mechanism 6 and then rotates, which can be used to scrape protrusions on the surface of the pressure roller 502. After the detachable pressure roller 5 moves to between the curtain and the direct light 803, the pressure roller 502 continues to rotate, which can be used to detect depressions on the surface of the pressure roller 502.

[0025] The rotating telescopic control component 4 includes a mounting base 401 which is installed on the side walls of the upper mesh plate 1 and the lower mesh plate 3 by screws. A rotating base 402 is arranged on the outer wall of the mounting base 401. An electrically driven multi-section telescopic rod 403 is fixedly arranged on the rotating base 402. The telescopic end can be extended to a position of 10-50 cm on the right side of the mesh plate 1. The electrically driven multi-section telescopic rod 403 is electrically driven and has a large telescopic space, so that the position of the pressure roller 502 can be flexibly adjusted in a large area to meet different usage requirements. The end of the detachable pressure roller 5 is inserted into the telescopic end of the electrically driven multi-section telescopic rod 403, and the position of the pressure roller 502 at the end is moved by the telescopic control of the electrically driven multi-section telescopic rod 403.

[0026] A rotation adjustment motor 404 is also installed on the mounting seat 401 on one side through a motor bracket 405. The output shaft of the rotation adjustment motor 404 is connected to the central axis of the rotating seat 402, and is used to control the swing of the electrically driven multi-section telescopic rod 403, thereby controlling the movement of the detachable pressure roller 5. The rotating seat 402 is rotationally adjusted by the rotation adjustment motor 404, and the telescopic effect of the electrically driven multi-section telescopic rod 403 is cooperated to enable the pressure roller 502 to be flexibly moved to different positions.

[0027] Specific as Figure 5 As shown, the detachable pressing roller 5 consists of a pressing roller 502 and a connecting seat 501 rotatably arranged at both ends of the pressing roller 502. A through hole is provided on the connecting seat 501, which is penetrated through the through hole on the telescopic end of the electrically driven multi-section telescopic rod 403. The pressing roller 502 can stably rotate on the connecting seat 501. After being pressed onto the film body, it can naturally rotate with the movement of the connecting seat 501 to press the film body, thereby realizing the film body bonding function.

[0030] The elastic scraping mechanism 6 is composed of two elastic telescopic rods 601 respectively fixed to the front and rear side walls of the screen board 1, and the telescopic ends of the two elastic telescopic rods 601 are connected with mounting plates 602, and a scraping wire 603 is fixedly arranged between the two mounting plates 602. The setting of the elastic telescopic rods 601 allows the pressure roller 502 to have a certain buffer space when it contacts the scraping wire 603, so as to avoid the pressure roller 502 breaking the scraping wire 603 in the absence of a buffer structure. At the same time, the elastic structure can provide a certain pressure between the pressure roller 502 and the scraping wire 603, so that the scraping wire 603 can fit more fully with the surface of the pressure roller 502, and can The protrusions on the surface of the pressure roller 502 can be scraped off better. At the same time, a vibration sensor can be installed on the scraping wire 603. When the surface of the pressure roller 502 is smooth, the scraping wire 603 will not vibrate significantly when it contacts the pressure roller 502. When scraping protruding particles that are difficult to remove, the scraping wire 603 will be pulled by the protrusions and will detach after being pulled to a certain extent. At this time, a significant vibration will occur. The vibration is detected by the vibration sensor, and a threshold value and an external reminder are set for the vibration sensor.

The black shadow projected by the pressure roller 502 on the screen is rectangular in shape. As the pressure roller 502 rotates continuously, the pressure roller 502 The projection arc surface of roller 502 is constantly switched, and the concave part is projected on the screen to form a rectangular concave notch. A monitoring box 805 is fixedly installed on the top of the projection frame 804, and the monitoring box 805 has a built-in mounting strip 806.

At this time, the pressure roller 502 is between the curtain and the direct light 803. Fig.10 As shown, specifically, the rotating seat 402 is rotated and adjusted by the rotating adjustment motor 404, thereby driving the electric-driven multi-section telescopic rod 403 to swing, and the electric-driven multi-section telescopic rod 403 swings and retracts at the same time, so that the pressure roller 502 is moved between the screen and the direct light 803, and then the direct light 803 is turned on, and the direct light 803 emits the direct light 803 light upward, and the shadow of the pressure roller 502 projected on the screen is rectangular in shape. As the pressure roller 502 continues to rotate, the projection arc surface of the pressure roller 502 is continuously switched, and the projection of the concave part on the screen will form a rectangular concave.
