Description

Technical Field

[0001] This application belongs to the field of coating application technology for silent tires, and relates to a coating application device for silent tires of new energy vehicles. Background Technology

[0002] The development of new energy vehicles has placed new demands on tire sound insulation performance. Sound-absorbing foam can absorb resonance between the tire and the road surface, effectively reducing tire noise generated during vehicle operation.

[0003] Currently, the application of sound-absorbing cotton to the inner wall of tires is mainly done manually, which is inefficient, labor-intensive, and the adhesion needs improvement. While some existing technologies use machine application, these still have shortcomings: due to factors such as poor device stability, the uniformity and thickness of the adhesive application cannot be effectively guaranteed. Utility Model Content

[0004] To address the aforementioned issues, this application proposes a coating application device for silent tires used in new energy vehicles. This device is highly efficient, ensures excellent adhesion between the coating and the inner side of the tire, and guarantees uniformity and thickness of the coating application.

[0005] The specific technical solution of this application is as follows:

[0006] A coating application device for quiet tires used in new energy vehicles, comprising: a coating device body,

[0007] The coating equipment body includes a sponge positioning device and a tire stabilizing device;

[0008] The tire stabilizing device includes a load-bearing plate and two rotating devices mounted above the load-bearing plate. Each rotating device includes two fixed columns and a rolling rod connected between the two fixed columns. An annular rolling wheel is mounted on the outer wall of the rolling rod. A motor is connected to the end of the rolling rod. A protective plate is mounted on the outside of the rotating device.

[0009] The sponge positioning device includes a paint receiving device, with a stabilizing platform below the paint receiving device; the paint receiving device has a hollow cavity extending along its length, the hollow cavity including a paint receiving space and a pushing space; a downward-facing discharge port is provided on the lower side wall of the end of the paint receiving device and communicates with the paint receiving space; the inner wall of the pushing space is threadedly connected to the telescopic rod; a baffle plate is provided between the receiving space and the pushing space.

[0010] Optionally, the shape of the discharge port is longitudinal; the length of the discharge port is 2 / 3 to 5 / 6 of the tire's inner diameter; and the width is 1 / 10 to 3 / 10 of the length.

[0011] Optionally, the coating receiving device may be L-shaped with the opening facing downwards.

[0012] Optionally, the outer wall of the telescopic rod is provided with threads and extends along the length of the telescopic rod, from one end to the other end.

[0013] Optionally, the distance between the two tire stabilizing devices is 1 / 3 to 2 / 3 of the tire's outer diameter.

[0014] Optionally, the upper surface of the protective plate is a cut surface facing the rolling wheel.

[0015] Optionally, a load-reducing groove is provided in the center of the load-bearing plate; the load-reducing groove is located between the two rotating devices; a clean plate is provided on the surface of the load-bearing plate near the opening of the load-reducing groove.

[0016] Optionally, the lower part of the protective plate is connected to a fixed post.

[0017] Optionally, the width of the load-reducing groove is 0.2-0.5 times the outer diameter of the tire.

[0018] The beneficial effects that this application may produce include, but are not limited to:

[0019] 1. The device of this application includes a sponge positioning device and a tire stabilizing device. A hollow cavity (paint receiving space and pushing space) extending along the length of the paint receiving device is provided inside the paint receiving device of the sponge positioning device; a baffle plate is provided between the paint receiving space and the pushing space; a telescopic rod is inserted into the paint receiving space and moves evenly in a threaded manner to push the paint in the paint receiving space, thereby achieving uniform discharge.

[0020] The tire stabilization device places the tire between two rotating devices within the device, causing the tire tread to contact two annular rolling wheels. A motor rotates the rolling rod connected between two fixed columns, which in turn drives the annular rolling wheels connected to the rolling rod to rotate at a constant speed (the rotation direction of the annular rolling wheels on the two rotating devices is the same), thereby achieving stable and uniform rotation of the tire.

[0021] 2. In a preferred embodiment, the outlet is shaped along its length; the length of the outlet is 2 / 3 to 5 / 6 of the tire's inner diameter; and the width is 1 / 10 to 3 / 10 of the length. This type of outlet ensures that the coating applied to the inner side of the tire has a certain width and thickness, and that during the discharge process, there is no need to move the coating receiving device to increase the width of the coating layer, which would cause uneven coating thickness.

[0039] As a specific implementation method, such as Figures 1-7As shown, a coating application device for silent tires includes: a coating device body, wherein the coating device body includes a sponge positioning device 2 and a tire stabilizing device 1;

[0040] The tire stabilizing device 1 includes a load-bearing plate 104 and two rotating devices (the two rotating devices are identical) disposed above the load-bearing plate 104; each rotating device includes two fixed columns 103, and a rolling rod 102 is connected between the two fixed columns 103. An annular rolling wheel 101 is provided on the outer wall of the rolling rod 102; a motor 107 is connected to the end of the rolling rod 102 (the fixed columns 103 are provided with through holes to connect the rolling column and the motor 107); a protective plate 106 is provided on the outside of the rotating device.

[0041] The sponge positioning device 2 includes a paint receiving device 201, with a stabilizing platform 204 below the paint receiving device 201; the paint receiving device 201 has a hollow cavity 205 extending along its length, the hollow cavity 205 including a paint receiving space 2051 and a pushing space 2052; a downward-facing discharge port 206 is provided on the lower side wall of the end of the paint receiving device 201 and communicates with the paint receiving space 2051; the inner wall of the pushing space 2052 is threadedly connected to the telescopic rod 202; a baffle plate 207 is provided between the receiving space and the pushing space 2052.

[0042] In practical use, the tire (outer diameter approximately 70cm, inner diameter approximately 64cm) is rolled from the protective plate 106 position between the two rotating devices placed in the tire stabilizing device 1 (the protective plate 106 serves two purposes: firstly, it allows the tire to roll between the two annular rolling wheels 101, reducing manual lifting and saving time and effort; secondly, it reinforces and protects the reinforcing column, enhancing stability), so that the tire tread contacts the two annular rolling wheels 101. The sponge positioning device 2 is pushed to the front of the tire stabilizing device 1 until the outlet 206 in the paint receiving device 201 faces the inside of the tire (the length direction of the outlet 206 is consistent with the width direction of the inside of the tire). Figure 7 As shown, the outer wall of the front portion (2 / 5 section) of the telescopic rod 202 is not threaded; as Figure 3 , Figure 4 As shown, Figure 4 This refers to the state in which the telescopic rod 202 is placed (or threadedly connected to) the paint receiving device 201; Figure 3 This refers to the state where the telescopic rod 202 is not placed in the paint receiving device 201. During use, first add paint to the paint receiving space 2051 of the hollow cavity 205 (the threaded portion of the inner wall cannot hold paint). After placement, place a baffle plate to separate it from the pushing space 2052, and then... Figure 3 The telescopic rod 202 shown is inserted into the hollow cavity 205 of the paint receiving device 201 until the outer wall of the telescopic rod 202 begins to connect with the inner wall of the hollow cavity 205. At this point, as the telescopic rod 202 advances along the thread, the front end of the telescopic rod 202 abuts against the baffle plate (e.g., Figure 4 As shown), the motor drives the baffle plate forward, which then squeezes the coating material forward until the coating material comes out of the outlet 206. At this time, the motor 107 at the end of the rolling rod 102 in the tire stabilizing device 1 is activated (the fixed column 103 has a through hole to connect the rolling column and the motor 107). The rotation of the motor 107 drives the rolling rod 102 connected between the two fixed columns 103 to rotate, which in turn drives the annular rolling wheel 101 connected to the rolling rod 102 to rotate at a constant speed (the rotation direction of the annular rolling wheels 101 on the two rotating devices is the same), thus achieving uniform rotation of the tire and quickly and accurately adhering the coating material to the inner wall of the tire. The coating material is then heated and foamed to form the tire's sound-absorbing layer.

[0043] In a preferred embodiment, the outlet 206 is elongated; the length of the outlet 206 is 2 / 3 to 5 / 6 of the tire's inner diameter; the width is 1 / 10 to 3 / 10 of the length. The width of the outlet 206 is equivalent to the thickness of the coating, and the length of the outlet 206 is equivalent to the width of the coating (the side that contacts the inner side of the tire). This specification of the outlet 206 ensures that the coating applied to the inner side of the tire has a certain width and thickness, and during the discharge process, there is no need to move the coating receiving device 201 to increase the width of the coating layer, which would cause uneven coating thickness.

[0044] In a preferred embodiment, the paint receiving device 201 has an L-shaped shape with the opening facing downwards. This allows for more precise positioning of the discharge port 206 to the inside of the tire.

[0045] In a preferred embodiment, the telescopic rod 202 has threads on its outer wall and extends along its length from one end to the other. This allows the telescopic rod 202 to have a relatively maximum range of motion, accommodating the installation of noise-reducing coatings on tires of different sizes.

[0046] In a preferred embodiment, the distance between the two tire stabilizing devices 1 is 1 / 3 to 2 / 3 of the tire's outer diameter. In this configuration, the tire can be securely positioned between the two rotating devices and can rotate in coordination with the rotation of the two annular rolling wheels 101.

[0047] In a preferred embodiment, the upper surface of the protective plate 106 is a cut surface facing the rolling wheel; this allows the tire to pass more smoothly between the two annular rolling wheels 101 during rolling.

[0048] In a preferred embodiment, a load-bearing groove 105 is provided in the center of the load-bearing plate 104; the load-bearing groove 105 is located in the middle of the two rotating devices (the distance between the two fixed columns 103 and the load-bearing groove 105 is the same);

[0049] A detachable cleaning plate 108 is provided on the surface of the load-bearing plate 104 near the opening of the load-reducing groove 105. This cleaning plate 108 is designed to prevent paint from dripping from the outlet 206 onto the load-bearing platform during the removal of the paint receiving device 201, which could cause severe staining and make cleaning difficult. The cleaning plate 108 can be easily removed for convenient cleaning. During use, the bottom of the tire is located within the load-reducing groove 105.

[0050] In a preferred embodiment, the lower part of the protective plate 106 is connected to the fixing post 103. The height of the connection portion will not exceed the bottom of the annular rolling wheel 101, which can enhance the stability of the fixing post 103.

[0051] In a preferred embodiment, the width of the load-reducing groove 105 is 0.2-0.5 times the outer diameter of the tire. This size of the load-reducing groove 105 provides sufficient space to accommodate the bottom of the tire, reducing the height of the tire above the support platform and thus reducing the height of the fixing column 103, thereby reducing production costs. This design also enhances the stability of the fixing column 103 by lowering the center of gravity.

[0052] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0053] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
