Description

Technical Field

[0001] This utility model relates to the field of foil application technology for rubber and plastic sheets, specifically to an automatic adhesive supply device for foil application in the deep processing of rubber and plastic sheets. Background Technology

[0002] Rubber-plastic composite (RPC) boards are a high-performance thermal insulation material with low thermal conductivity, excellent fire resistance, and superior moisture and water resistance. They are also soft, flexible, and easy to cut. Current technology involves applying foil to the surface of RPC boards to enhance their performance, such as improving moisture resistance, reflective heat insulation, and UV resistance. However, foil application machines are bulky and can only accommodate one size of RPC board. This necessitates multiple foil application machines to produce various sizes of foil-coated RPC boards, or the use of cutting machines to divide the boards into different widths. This not only requires a large floor space but also significantly increases costs. Utility Model Content

[0003] The purpose of this invention is to provide an automatic adhesive supply device for foil lamination in the deep processing of rubber and plastic sheets, so as to solve the above-mentioned shortcomings in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic adhesive supply device for foil application in deep processing of rubber and plastic boards, comprising: a mounting frame, on which two symmetrically arranged sliding grooves are provided; a bidirectional threaded screw is rotatably arranged inside the mounting frame; the two parts of the bidirectional threaded screw located in the two sliding grooves have opposite thread directions; a slider is slidably arranged in each sliding groove; the slider is threadedly connected to the bidirectional threaded screw; an adhesive spraying assembly is fixedly connected to the bottom of the slider; and an adhesive spraying assembly is also fixedly connected to the bottom middle part of the mounting frame.

[0005] Furthermore, the middle part of the bidirectional threaded screw is connected to the mounting bracket via a bearing, and the two sliders are arranged symmetrically about the bearing.

[0006] Furthermore, the adhesive spraying assembly includes a nozzle body, a nozzle is fixedly connected to the bottom of the nozzle body, an adhesive inlet pipe communicating with the nozzle is provided on the side of the nozzle body, and an air inlet pipe communicating with the nozzle is provided on the top of the slider.

[0007] Furthermore, the slider and the nozzle body have an air intake channel in the vertical direction, and the nozzle body has a glue inlet channel in the horizontal direction. The air intake channel is connected to the air intake pipe, and the glue inlet channel is connected to the glue inlet pipe.

[0008] Furthermore, a scale is engraved on the top of the mounting bracket, and a pointer is fixedly connected to the top of the slider near the scale.

[0009] Furthermore, a motor is mounted on the side of the mounting bracket, and the output shaft of the motor is fixedly connected to one end of a bidirectional threaded screw.

[0010] The beneficial effects of the automatic adhesive supply device for foil lamination in the deep processing of rubber and plastic sheets provided by this utility model are as follows:

[0011] This invention changes the spraying range by rotating a bidirectional threaded screw to alter the distance between two sliders, thereby adjusting the distance between the two adhesive spraying components. When the spraying range shrinks, the adhesive spraying components mounted on the mounting frame stop working to avoid repeated spraying. It is suitable for applying foil to rubber and plastic sheets of different widths, improving the practicality of the equipment, reducing investment costs, and lowering the investment risk for enterprises.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0021] Please see Figures 1-3 An automatic adhesive supply device for foil application in deep processing of rubber and plastic sheets includes: a mounting frame 1, on which two symmetrically arranged grooves 3 are provided; a bidirectional threaded screw 4 is rotatably installed inside the mounting frame 1; the two parts of the bidirectional threaded screw 4 located in the two grooves 3 have opposite thread directions; a slider 2 is slidably installed in each groove 3; the slider 2 is threadedly connected to the bidirectional threaded screw 4; an adhesive spraying assembly is fixedly connected to the bottom of the slider 2; an adhesive spraying assembly is also fixedly connected to the bottom middle part of the mounting frame 1; the middle part of the bidirectional threaded screw 4 is connected to the mounting frame 1 through a bearing; the two sliders 2 are symmetrically arranged about the bearing; the two sliders 2 are respectively threadedly connected to the two sections of opposite threads on the bidirectional threaded screw 4; so that when the bidirectional threaded screw 4 rotates, the two sliders 2 are limited by the grooves 3, and the two sliders 2 move away from each other or move closer to each other; and the parts of the bidirectional threaded screw 4 that contact the mounting frame 1 are all connected by bearings to reduce frictional resistance, that is, both ends and the middle part of the bidirectional threaded screw 4 are connected to the mounting frame 1 through bearings.

[0022] This invention changes the spraying range by rotating the bidirectional threaded screw 4 to change the distance between the two sliders 2, thereby adjusting the distance between the two glue spraying components. When the spraying range shrinks, the glue spraying components mounted on the mounting frame 1 stop working to avoid repeated spraying. It is suitable for applying foil to rubber and plastic sheets of different widths, improving the practicality of the equipment, reducing the investment cost of the equipment, and reducing the investment risk of enterprises.

[0023] Furthermore, the glue spraying assembly includes a nozzle body 8, with a nozzle 9 fixedly connected to the bottom of the nozzle body 8. A glue inlet pipe 10 communicating with the nozzle 9 is provided on the side of the nozzle body 8. An air inlet pipe 11 communicating with the nozzle 9 is provided on the top of the slider 2. An air inlet channel 12 is formed vertically within the slider 2 and the nozzle body 8, and a glue inlet channel 13 is formed horizontally within the nozzle body 8. The air inlet channel 12 communicates with the air inlet pipe 11, and the glue inlet channel 13 communicates with the glue inlet pipe 10. The slider 2 is a commercially available product; it can adjust the glue spraying range and can further adapt to rubber and plastic sheets of different widths for glue spraying. The glue inlet pipe 10 introduces the glue into the glue inlet channel 13, which is then impacted by pressurized gas injected from the air inlet channel 12, causing the glue to atomize and be sprayed out through the nozzle 9.

[0024] Furthermore, a scale 7 is engraved on the top of the mounting bracket 1, and a pointer 6 is fixedly connected to the top of the slider 2 near the scale 7. The two-way threaded screw 4 drives the two sliders 2 to move in the slide groove 3, causing the pointer 6 to slide on the top of the mounting bracket 1. By observing the value on the scale 7 corresponding to the tip of the pointer 6, the moving distance of the slider 2 can be determined, thereby adjusting the total glue spraying range to adapt to rubber and plastic insulation boards of different widths.

[0025] Furthermore, a motor 5 is mounted on the side of the mounting bracket 1. The output shaft of the motor 5 is fixedly connected to one end of the bidirectional threaded screw 4. The motor 5 is a servo motor, which can precisely control the forward and reverse rotation and the number of rotations of the bidirectional threaded screw 4.

[0026] In this utility model, reference Figures 1 to 3 By debugging the machine, a summary table of rubber and plastic sheets of different widths corresponding to the movement of slider 2 at a specified distance was obtained. Subsequently, when facing rubber and plastic sheets of different widths, the slider 2 can be moved a specified distance by controlling motor 5 to drive the bidirectional threaded screw 4 to rotate. A glue spraying assembly is also provided at the bottom of the middle part of the mounting frame 1. Its components are the same as those of the glue spraying assembly below slider 2. The difference is that its air inlet pipe 11 is connected to the top of the mounting frame 1, and the air inlet channel 12 is opened in the vertical direction between the mounting frame 1 and the nozzle body 8. When the width of the rubber and plastic sheet to be coated with foil is small, the glue spraying assembly installed in the middle of the mounting frame 1 stops working, saving glue.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
