Description

Technical Field

[0001] The utility model relates to the technical field of laminating machines, in particular to a laminating glue flow regulating device. Background Art

[0002] Laminating machines are usually used to cover a layer of film on the surface of paper, plastic film or other materials to increase their gloss, protection or change their surface properties. During the laminating process, in order to evenly coat the glue on the surface of the material to be laminated and ensure that the film can firmly adhere to the surface, a glue flow regulating device is needed to control the amount of glue output, avoiding too much or too little glue output and affecting the laminating effect.

[0003] For example, in Chinese Patent Application No. CN201921979961.6, a glue control device for the production of sealing tapes is provided, which includes an inclined tee and a valve for controlling the flow rate provided on the inclined tee. The inclined tee includes a straight branch pipe one, a straight branch pipe two and an inclined branch pipe, and the flow rate of the glue is controlled by the valve.

[0004] However, when this type of valve is in use, since the glue is sucked by the pump body and impacts the valve core when passing through the valve core, the valve core may shift during use, resulting in a change in the amount of glue output and affecting the production effect.

[0005] Therefore, in view of this problem, the utility model provides a laminating glue flow regulating device. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the problem in the prior art that when the glue is sucked by the pump body and impacts the valve core when passing through the valve core, the valve core may shift during use, resulting in a change in the amount of glue output and affecting the production effect, and a laminating glue flow regulating device is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A laminating glue flow regulating device includes a spray gun. A circular shell is communicated with the side surface of the spray gun. A connecting pipe is communicated with the side surface of the circular shell away from the spray gun. The connecting pipe is connected to the glue outlet end of the pump body. A valve rod is rotatably arranged on the inner wall of the circular shell through a sealing bearing. A valve core is fixed to one end of the valve rod located in the circular shell. A turntable is fixed to the end of the valve rod away from the valve core. A limiting strip is fixed to the outer surface of the turntable. An anti-rotation mechanism for limiting the limiting strip is arranged on the outer surface of the circular shell, and an auxiliary mechanism is also arranged on the anti-rotation mechanism.

[0009] Preferably, the anti-rotation mechanism includes a mounting box fixed on the outer surface of the circular housing. A moving block is arranged inside the mounting box. A clamping strip is fixed on the side surface of the moving block. The clamping strip slides on the inner wall of the mounting box and is clamped with the limiting strip.

[0010] Preferably, the anti-rotation mechanism further includes a return spring arranged inside the mounting box. Two ends of the return spring are respectively and fixedly connected with the mounting box and the moving block.

[0011] Preferably, the anti-rotation mechanism further includes rectangular blocks fixed on two side surfaces of the clamping strip. Sliding grooves are formed on two side surfaces of the mounting box. The rectangular blocks slide in the corresponding sliding grooves.

[0012] Preferably, the auxiliary mechanism includes a mounting strip fixed on the top of the mounting box. A mounting groove is formed on the top of the moving block. A first magnet is fixed inside the mounting groove.

[0013] Preferably, the auxiliary mechanism further includes a pull rod sliding inside the mounting strip. A second magnet is fixed at the bottom end of the pull rod. The second magnet is magnetically attracted to the first magnet.

[0014] Compared with the prior art, the utility model provides a film laminating glue flow regulating device, which has the following beneficial effects:

[0015] For this film laminating glue flow regulating device, through the settings of the valve rod, the valve core, the turntable and the limiting strip, during coating, the flow rate of the glue can be adjusted to avoid the glue output being too large or too small, which affects the film laminating effect. Through the setting of the anti-rotation mechanism, after the flow rate of the glue is adjusted, the limiting strip can be limited to prevent the valve core from shifting under the impact of the glue, so as to cause the change of the glue output size and affect the production effect. Through the setting of the auxiliary mechanism, it is prevented that the anti-rotation mechanism is started under the action of external force, so as to release the limitation on the limiting strip, and further prevent the valve core from shifting under the impact of the glue.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. Embodiment 1

[0023] Referring to Figures 1 - 4 , a film laminating glue flow rate regulating device includes a spray gun 1. A circular shell 2 is connected to the side of the spray gun 1. A connecting pipe 3 is connected to the side of the circular shell 2 away from the spray gun 1. The connecting pipe 3 is connected to the glue outlet end of the pump body. A valve rod 4 is rotatably mounted on the inner wall of the circular shell 2 through a sealing bearing. A valve core 5 is fixed to one end of the valve rod 4 located inside the circular shell 2. A turntable 6 is fixed to the other end of the valve rod 4 away from the valve core 5. A limit strip 7 is fixed to the outer surface of the turntable 6. An anti-rotation mechanism 8 for limiting the limit strip 7 is provided on the outer surface of the circular shell 2. An auxiliary mechanism 9 is further provided on the anti-rotation mechanism 8.

[0024] Referring to Figures 1 - 4 , the anti-rotation mechanism 8 includes an installation box 81 fixed to the outer surface of the circular shell 2. A moving block 82 is arranged inside the installation box 81. A card strip 83 is fixed to the side of the moving block 82. The card strip 83 slides on the inner wall of the installation box 81 and is engaged with the limit strip 7.

[0025] Referring to Figures 1 - 4 , the anti-rotation mechanism 8 further includes a return spring 84 arranged inside the installation box 81. Both ends of the return spring 84 are fixedly connected to the installation box 81 and the moving block 82 respectively.

[0026] Referring to Figures 1 - 4, the anti-rotation mechanism 8 further includes rectangular blocks 85 fixed to both side surfaces of the strip 83. Slide grooves 86 are provided on both side surfaces of the mounting box 81, and the rectangular blocks 85 slide in the corresponding slide grooves 86.

[0027] In the present utility model, during use, the connecting pipe 3 is connected to the liquid outlet end of the pump body through a hose. The object to be film-coated is placed on the frame and fixed. During film coating, by starting the pump body, the glue in the glue tank is sucked into the spray gun 1, and a layer of film is covered on the surface of the object to be film-coated through the spray gun 1. When the glue flows through the circular housing 2, the valve rod 4 can be rotated. The valve rod 4 drives the valve core 5 to rotate by a certain angle, so that the glue output can be controlled according to the actual situation. In order to prevent the valve core 5 from shifting under the impact of the glue, a limiting strip 7 is provided on the outer surface of the turntable 6. When the turntable 6 is rotated, the moving block 82 can be slid backward in the mounting box 81 to squeeze the return spring 84, so that the strip 83 also slides backward to release the restriction on the limiting strip 7. After rotating the turntable 6 and adjusting the angle of the valve core 5, the moving block 82 can be released, and the elastic force of the return spring 84 is used to drive the moving block 82 and the strip 83 to reset, so that the strip 83 is engaged with the corresponding limiting strip 7 to limit the turntable 6. In this way, after adjusting the glue flow rate, the limiting strip 7 can be limited to prevent the valve core 5 from shifting under the impact of the glue, resulting in a change in the glue output and affecting the production effect. By sliding the rectangular block 85 in the slide groove 86, it is convenient for the user to pull the moving block 82 and also improves the stability of the moving block 82 during movement. Embodiment 2

[0028] Refer to Figures 1 - 4 , a film coating glue flow rate adjusting device, including a spray gun 1. A circular housing 2 is communicated with the side surface of the spray gun 1. A connecting pipe 3 is communicated with the side surface of the circular housing 2 away from the spray gun 1. The connecting pipe 3 is connected to the glue outlet end of the pump body. The inner wall of the circular housing 2 is rotated by a valve rod 4 through a sealing bearing. One end of the valve rod 4 located inside the circular housing 2 is fixed with a valve core 5. The end of the valve rod 4 away from the valve core 5 is fixed with a turntable 6. A limiting strip 7 is fixed on the outer surface of the turntable 6. An anti-rotation mechanism 8 for limiting the limiting strip 7 is provided on the outer surface of the circular housing 2. An auxiliary mechanism 9 is further provided on the anti-rotation mechanism 8.

[0029] Refer to Figures 1 - 4 , the auxiliary mechanism 9 includes a mounting strip 91 fixed to the top of the mounting box 81. A mounting groove 92 is provided on the top of the moving block 82, and a magnet 93 is fixed in the mounting groove 92.

[0030] Refer to Figures 1 - 4 , the auxiliary mechanism 9 further includes a pull rod 94 slidably arranged in the mounting strip 91. A magnet 95 is fixed to the bottom end of the pull rod 94, and the magnet 95 is magnetically attracted to the magnet 93.

[0031] In the present utility model, when it is necessary to pull the moving block 82, the pull rod 94 can be pulled upward in the mounting strip 91. The pull rod 94 drives the second magnet 95 to move upward, separating the second magnet 95 from the first magnet 93. When the moving block 82 is reset, the pull rod 94 slides downward, causing the second magnet 95 to move back into the mounting groove 92 and contact the first magnet 93. Since the first magnet 93 and the second magnet 95 are magnetically attracted to each other, the moving block 82 can be limited in position. In this way, the moving block 82 is prevented from sliding backward under the action of an external force, thereby releasing the limitation on the limiting strip 7 and further preventing the valve core 5 from shifting under the impact of glue.

[0032] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
