Description

Technical Field

[0001] This utility model relates to the field of butyl damping film production technology, and in particular to a butyl damping film extrusion and bubble removal device. Background Technology

[0002] Butyl damping film is a sheet material with damping properties made primarily from butyl rubber and various additives. It has wide applications in many fields. Butyl rubber has excellent air tightness, water tightness, weather resistance, and chemical corrosion resistance, making it the main film-forming material for butyl damping film. Damping sheets, also called putty or damping blocks, are viscoelastic materials that are applied to the inner surface of a car body, adhering tightly to the steel plate wall of the car body. Their main purpose is to reduce noise and vibration, that is, to provide damping. During the production process of butyl damping film, air bubbles are generated inside. Before leaving the factory, these bubbles need to be removed, so an extrusion degassing device is used to degas the material.

[0003] Existing technologies, such as the patent with publication number CN221908588U, disclose a device for extruding and de-bubbling butyl damping film. This patent uses a base with an extrusion device at the top and a cleaning mechanism at the top. The cleaning mechanism includes: a cleaning roller, which is located above the base, with bearings on the rotating shafts at both ends of the cleaning roller; support plates rotatably connected to both ends of the cleaning roller; a connecting rod rotatably connected to the inner side of the support plate; and a scraper fixedly connected to the top of the connecting rod; and a drive assembly, which is located inside the support plate and is used to drive the connecting rod to rotate. This utility model solves the problem that when existing equipment is used, there may be foreign objects on the surface of the product. When these foreign objects are extruded by the active and driven rollers, they may become embedded in the product and even cause damage to the product surface.

[0004] In daily operation, during the use of the equipment, the produced materials are prone to contain air bubbles, which affects the elasticity of the materials and causes poor material properties. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where material bubbles are difficult to expel quickly, and to propose a butyl damping film extrusion bubble removal device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a butyl damping film extrusion and de-airing device, comprising a mounting base, a main body, a first motor, a threaded extruder, a material hopper, and an extruder. The main body is fixedly connected to the upper surface of the mounting base, the threaded extruder is fixedly connected to one end of the main body, the first motor is fixedly connected to the side of the main body away from the threaded extruder, the material hopper is fixedly connected to the upper surface of the threaded extruder, and the extruder is fixedly connected to the end of the threaded extruder away from the main body.

The mounting frame is fixedly connected to the upper surface of the mounting base, the first roller is rotatably connected inside the mounting frame, a second roller is slidably connected inside the mounting frame, and connecting frames are rotatably connected to both ends of the second roller. A cylinder is fixedly connected to the lower surface of the connecting frame.

[0007] Furthermore, a first rotating wheel is fixedly connected to one end of the first roller, and a second rotating wheel is provided below the first rotating wheel. By providing the first rotating wheel, the first roller can be rotated, reducing the situation where the first roller is difficult to rotate during use.

[0008] Furthermore, the first and second rotating wheels are connected by a belt, and a second motor is fixedly connected to the side of the second rotating wheel away from the mounting frame. The second motor is provided to facilitate the rotation of the second rotating wheel.

[0009] Furthermore, a limiting frame is fixedly connected to the surface of the second motor. The limiting frame is fixedly connected to the upper surface of the mounting base, and the limiting frame is provided to facilitate limiting the movement of the second motor.

[0010] Furthermore, an auxiliary component is fixedly installed on the upper surface of the mounting base. The auxiliary component is located between the extruder and the exhaust device. The auxiliary component includes a stabilizing frame and a blower. The stabilizing frame is fixedly connected to the upper surface of the mounting base, and the blower is fixedly connected to the upper end of the stabilizing frame. An air outlet is fixedly connected to the side of the blower near the extruder. By setting the air outlet, foreign objects on the surface of the material can be blown away, reducing the possibility of foreign objects easily contaminating the material surface during equipment use.

[0011] Furthermore, an air inlet is fixedly connected to the end of the blower away from the air outlet, and a third motor is fixedly connected to the side of the blower. The air inlet can prevent foreign objects in the air from entering the blower.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1.

This exhaust device vents the material by squeezing between the first roller and the second roller, which improves the practicality of the equipment.

[0015] 2. In this utility model, by setting an auxiliary component, the surface of the material is effectively cleaned, which plays the role of blowing away foreign objects on the surface of the material. This reduces the situation where foreign objects on the surface of the material are easily squeezed into the interior of the material during the extrusion and exhaust of the equipment, causing material contamination and making the material unusable. This auxiliary component can blow away foreign objects on the surface of the material, improving the cleanliness of the material surface. Attached Figure Description

[0022] Please see Figures 1-5This utility model provides a technical solution: a butyl damping film extrusion and de-airing device, including a mounting base 1, a main body 2, a first motor 3, a threaded extruder 4, a material hopper 5, and an extruder 6. The main body 2 is fixedly connected to the upper surface of the mounting base 1, the threaded extruder 4 is fixedly connected to one end of the main body 2, the first motor 3 is fixedly connected to the side of the main body 2 away from the threaded extruder 4, the material hopper 5 is fixedly connected to the upper surface of the threaded extruder 4, and the extruder 6 is fixedly connected to the end of the threaded extruder 4 away from the main body 2.

[0023] The threaded extruder 4 is made of alloy steel and has a gradually decreasing threaded channel inside. From the feed end to the discharge end, the thread pitch gradually decreases and the depth gradually becomes shallower. This structure allows the material to be subjected to continuous and increasing extrusion pressure during movement. The material hopper 5 is a funnel-shaped structure made of stainless steel. The inner wall is polished to reduce material adhesion and ensure smooth feeding. The discharge port of the extruder 6 is designed to be flat, and its width is consistent with the target width of the butyl damping film to ensure that the extruded film has a regular shape.

[0024] The following section will describe the specific settings and functions of its exhaust device 7 and auxiliary components 8.

[0025] In this embodiment: an exhaust device 7 is fixedly installed on the upper surface of the mounting base 1. The exhaust device 7 is located at the discharge end of the extruder 6. The exhaust device 7 includes a mounting frame 71 and a first roller 72. The mounting frame 71 is fixedly connected to the upper surface of the mounting base 1. The first roller 72 is rotatably connected inside the mounting frame 71. A second roller 73 is slidably connected inside the mounting frame 71. The two ends of the second roller 73 are rotatably connected to a connecting frame 74. A cylinder 75 is fixedly connected to the lower surface of the connecting frame 74.

[0026] Specifically, a first roller 72 is fixedly connected to a first rotating wheel 76 at one end, and a second rotating wheel 77 is disposed below the first rotating wheel 76.

[0027] In this embodiment: by setting the first rotating wheel 76, the first roller 72 can be rotated, reducing the situation where the first roller 72 is difficult to rotate when the device is in use.

[0028] Specifically, the first rotating wheel 76 and the second rotating wheel 77 are connected by a belt. The second rotating wheel 77 is fixedly connected to a second motor 78 on the side away from the mounting bracket 71. The second motor 78 is provided to facilitate the rotation of the second rotating wheel 77.

[0029] Specifically, a limit frame 79 is fixedly connected to the surface of the second motor 78. The limit frame 79 is fixedly connected to the upper surface of the mounting base 1. The limit frame 79 is provided to facilitate the limiting of the second motor 78.

[0030] In this embodiment: An auxiliary component 8 is fixedly installed on the upper surface of the mounting base 1. The auxiliary component 8 is located between the extruder 6 and the exhaust device 7. The auxiliary component 8 includes a stabilizing frame 81 and a blower 82. The stabilizing frame 81 is fixedly connected to the upper surface of the mounting base 1, and the blower 82 is fixedly connected to the upper end of the stabilizing frame 81. An air outlet 83 is fixedly connected to the side of the blower 82 near the extruder 6.

[0031] In this embodiment, by setting the air outlet 83, foreign objects on the surface of the material can be blown away, reducing the likelihood of foreign objects contaminating the material surface during use.

[0032] The air outlet 83 has a flat opening structure, the width of which is the same as the width of the material. A guide plate is installed at the air outlet to evenly distribute the blown airflow on the surface of the material. The air inlet 84 is equipped with multiple layers of filters, including a coarse filter, a medium filter, and an activated carbon filter, which can effectively block dust, particles, and other foreign objects in the air from entering the blower 82, while also absorbing odors in the air to prevent contamination of the material.

[0033] Specifically, an air inlet 84 is fixedly connected to the end of the blower 82 away from the air outlet 83, and a third motor 85 is fixedly connected to the side of the blower 82. The third motor 85 is a high-efficiency and energy-saving motor that drives the impeller of the blower 82 to rotate and provides a stable air volume. The air inlet 84 can prevent foreign objects in the air from entering the interior of the blower 82.

[0034] Specifically, a support base 86 is fixedly connected to the surface of the third motor 85, and the support base 86 is fixedly connected to the surface of the stabilizer 81.

[0035] During equipment operation, the third motor 85 is started to drive the blower 82 to operate. After being filtered by the air inlet 84, the air is blown onto the material surface in a uniform airflow through the air outlet 83. This can effectively remove dust, debris and other foreign objects from the material surface, reduce the amount of foreign objects mixed into the material during the exhaust and extrusion process, and ensure the product quality and performance of the butyl damping film.

[0036] Working Principle: During operation, raw materials are fed into the screw extruder 4 through the material hopper 5. The first motor 3 is then started, driving the screw extruder to move and heat the raw materials within the screw extruder 4. The materials are then discharged through the extruder 6. After the discharged material connects to the surface of the first roller 72, the cylinder 75 is activated, moving the connecting frame 74 to move the second roller 73, further compressing the material on the surface of the first roller 72. Simultaneously, the second motor 78 is activated, driving the second rotating wheel 77 to rotate, which in turn drives the first rotating wheel 76 via a belt, causing the first roller 72 to rotate and roll, compress, and expel the material. The exhaust device 7 effectively vents the material after production, providing rapid venting and reducing the problem of air bubbles inside the material after production, which affects the material's elasticity and leads to poor material properties, as is common in existing equipment. This exhaust device 7, through the compression between the first roller 72 and the second roller 73, vents the material, improving the equipment's practicality.

[0037] After pressurization, the third motor 85 is started to drive the blower 82 to operate, drawing air into the blower 82 through the air inlet 84 and then expelling the air through the air outlet 83 to clean the surface of the material. By setting up the auxiliary component 8, the surface of the material is effectively cleaned, which plays a role in blowing away foreign objects on the surface of the material. This reduces the situation where foreign objects on the surface of the material are easily squeezed into the material during the extrusion and exhaust of the equipment, causing material contamination and making the material unusable. This auxiliary component 8 can blow away foreign objects on the surface of the material, improving the cleanliness of the material surface.
