[0030] Rough or burred tire tread tape can severely impact tire quality. The broken, fuzzy material can adhere to tire components, and tires using components contaminated with tread tape debris are prone to problems such as tread delamination and sidewall bulges, resulting in defective products. Traditionally, repairing rough tire tread tape has relied on manual labor.

[0031] Specifically, in the traditional edge-sealing repair process, two workers use high-powered soldering irons to repair the frayed edges of the padding strip point by point, thus removing the burrs. To limit the back-and-forth rolling of the padding strip and avoid affecting the heating efficiency or threatening the workers' safety, a piece of wood is placed in front of and behind the padding strip. Traditional manual repair has at least the following drawbacks:

[0032] (1) Workers need to hold an electric soldering iron to heat the edges. Workers cannot stay away from the heated parts, which means there is little safety protection for workers and the risk of burns is easy to occur.

[0033] (2) Poor quality of the heat-sealing edge of the pad, difficulty in controlling or adjusting the temperature of the soldering iron, and the tendency for the heat-sealing edge area to produce focused clumps of dot-like material, which can easily burn non-burr areas and have an adverse effect on tire quality.

[0034] (3) Manually ironing the edges of the padding tape is inefficient. One person can only do about 5 rolls of padding tape per day. The labor cost is high and the work efficiency is low.

[0035] Reference Figures 1 to 3 As shown, one embodiment of the present invention provides a padding edge ironing device to improve the ironing effect and repair efficiency of padding edges while ensuring worker safety. Specifically, the padding edge ironing device includes a conveying mechanism 100, an ironing mechanism 200, and a base plate 300.

[0036] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, both the conveying mechanism 100 and the ironing mechanism 200 are connected to the upper end of the base plate 300. The base plate 300 provides support for the conveying mechanism 100 and the ironing mechanism 200, and allows for easy adjustment of their relative positions. The conveying mechanism 100 is configured to convey a pad. The ironing mechanism 200 is configured to iron the edges of the pad.

[0037] Reference Figure 1 , Figure 2 and Figure 3As shown, specifically, the ironing mechanism 200 includes two heating plates 210 arranged on the left and right. The two heating plates 210 are arranged at right angles to the base plate 300. Taking the base plate 300 as an example where it is arranged horizontally, the two heating plates 210 are arranged vertically and are parallel to each other. A repair space 240 is constructed between the two heating plates 210. The spacing of the repair space 240 can be adapted to the width of the padding strip.

[0038] Reference Figure 1 , Figure 2 and Figure 3 As shown, the conveying mechanism 100 is configured to drive the pad belt through the repair space 240. During the conveying process of the pad belt, two heating plates 210 can respectively abut against the two sides of the pad belt along the width direction. Through the heating of the heating plates 210, the two sides of the pad belt along its width direction can be heated to achieve the repair of broken and pilling fuzzy material.

[0039] Reference Figure 1 , Figure 2 and Figure 3 As shown, compared with the traditional manual edge-ironing repair method, the padding tape edge-ironing device provided in this embodiment of the utility model can reduce the dependence on manual operation, thereby improving the quality of padding tape edge repair. The padding tape treated by the padding tape edge-ironing device has smooth and neat edges, no burrs, and is firm and durable, improving the efficiency of padding tape edge ironing. The efficiency of the padding tape edge-ironing device is about 30 times higher than that of manual edge ironing, and it allows workers to maintain a safe distance from heat sources to ensure the safety of the operation and protect the personal safety of workers.

[0040] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the hot edge mechanism 200 also includes two heat-resistant components 220 arranged on the left and right. Two heating plates 210 are connected to the two heat-resistant components 220 respectively. The two heating plates 210 are arranged facing each other, that is, the two heat-resistant components 220 respectively form the left and right boundaries of the repair space 240, which helps to reduce the risk of damage to external personnel when they approach the hot edge mechanism 200.

[0041] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the heat-resistant component 220 can be a refractory brick, that is, the two heating plates 210 are respectively connected to the two refractory bricks, so that the heat-resistant component 220 has good heat resistance and low cost.

[0042] Reference Figure 1 , Figure 2 and Figure 3As shown, specifically, the heating plate 210 can be a ceramic heating plate 210. The ceramic heating plate 210 has high heating uniformity and fast heating speed, which can be well adapted to the edge repair of the pad.

[0043] Reference Figure 1 , Figure 2 and Figure 3 As shown, it is understood that the padding edge heating device also includes at least two first connectors. Each set of heat-resistant components 220 and heating plates 210 is connected to at least one first connector. The first connectors pass through the heat-resistant components 220 and heating plates 210, so that the heat-resistant components 220 and heating plates 210 can be detachably connected.

[0044] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the first connector can be a bolt, screw or other threaded connector. Each set of heat-resistant components 220 and heating plates 210 is connected to multiple first connectors. The first connectors are inserted into the heat-resistant components 220 and heating plates 210. Through the connection of multiple first connectors, multi-point detachable connection between the heat-resistant components 220 and heating plates 210 can be realized, which is beneficial to improving the connection stability between the heat-resistant components 220 and heating plates 210.

[0045] Reference Figure 1 , Figure 2 and Figure 3 As shown, the heat-resistant component 220 and the heating plate 210 adopt a detachable modular design. By disassembling the first connector, the heating plate 210 can be quickly replaced to facilitate the maintenance of the heating plate 210.

[0046] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that, specifically, the hot edge mechanism 200 also includes two supports 230, two sets of heat-resistant components 220 and heating plate 210 are respectively connected to the two supports 230, and the supports 230 are connected to the lower end of the heat-resistant components 220.

[0047] Reference Figure 1 , Figure 2 and Figure 3 As shown, the upper end of the support 230 is connected to the heat-resistant component 220, while the lower end of the support 230 is connected to the base plate 300. This allows the heating plate 210 and the heat-resistant component 220 to be mounted at an elevated position, enabling the adjustment of the setting height of the repair space 240 to match the conveying height of the conveying mechanism 100. This allows the pad conveyed by the conveying mechanism 100 to pass through the repair space 240, allowing the heating plate 210 to heat-repair the edges of both sides of the pad. The elevated position also improves the heat dissipation efficiency of the heating plate 210, thereby enhancing the safety of the pad heating device.

[0048] Reference Figure 1 , Figure 2 and Figure 3 As shown, it should be noted that the support 230 can be made of angle iron.

[0049] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the pad heating edge device also includes two temperature sensors, which are respectively attached to two heating plates 210. The controller is configured to control the heating temperature of the heating plates 210 according to the detection values ​​of the temperature sensors.

[0050] Reference Figure 1 , Figure 2 and Figure 3 As shown, the temperature sensor can be attached to the heating plate 210, making the temperature sensor more evenly heated, thereby improving the accuracy of detecting the heating temperature of the heating plate 210. The controller is configured to control the heating temperature of the heating plate 210 according to the detection value of the temperature sensor. The controller can control the heating temperature of the heating plate 210 at about 210℃.

[0051] Reference Figure 1 , Figure 2 and Figure 3 As shown, compared to the difficulty in controlling the heating temperature of the soldering iron in traditional edge repair, the padding edge repair device provided in this embodiment can also adjust the heating temperature of the heating plate 210 according to the thickness of the padding. Through the cooperation of the temperature sensor and the controller, the heating and temperature of the heating plate 210 are easy to adjust and control, which can improve the adaptability to padding of various thicknesses.

[0052] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the temperature sensor can be a thermocouple, which can be fixed tightly to the heating plate 210 by screws, so that the thermocouple and the heating plate 210 are more stable and the thermocouple is heated fully and evenly.

[0053] Reference Figure 1 , Figure 2 and Figure 3 As shown, the padding edge pressing device also includes a frame, and the conveying mechanism 100 includes an unwinding roller 110 and a take-up roller 120. The following description uses the conveying mechanism 100 conveying the padding from back to front as an example. The lower end of the frame is connected to the base plate 300, and the unwinding roller 110 and take-up roller 120 are connected to the upper end of the frame and rotatably connected to it. Both ends of the unwinding roller 110 and take-up roller 120 are arranged in the left-right direction.

[0054] Reference Figure 1 , Figure 2 and Figure 3 As shown, the unwinding roller 110 and the take-up roller 120 are respectively located behind and in front of the ironing mechanism 200. The unwinding roller 110 is used to unwind the padding tape, and the take-up roller 120 is used to take up the padding tape.

[0055] Reference Figure 1 , Figure 2 and Figure 3 As shown, in the initial state, the padding strip can be in roll form and wound around the unwinding roller 110, with the free end of the padding strip connected to the take-up roller 120. In use, the padding strip hot-edge device can gradually unwind the padding strip forward by rotating the unwinding roller 110 relative to the frame, and gradually rewind the padding strip forward by rotating the take-up roller 120 relative to the frame, so that the padding strip passes through the repair space 240 of the hot-edge mechanism 200 and is gradually conveyed forward. The hot-edge mechanism 200 can hot-edge both sides of the padding strip during the conveying process to repair the broken and pilling fuzz on the edge of the padding strip.

[0056] Reference Figure 1 , Figure 2 and Figure 3 As shown, it is understandable that the conveying mechanism 100 also includes a guide roller parallel to the take-up roller 120. The guide roller is located between the ironing mechanism 200 and the take-up roller 120. The padding tape passes around the take-up roller 120, the guide roller, and the take-up roller 120 in sequence. The guide roller is used to guide or change the direction of the padding tape so that the padding tape is taut. In conjunction with the unwinding roller 110 and the take-up roller 120, stable conveying of the padding tape can be achieved.

[0057] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, two guide rollers are provided, named the first guide roller 130 and the second guide roller 140 respectively. The first guide roller 130 and the second guide roller 140 are arranged sequentially from back to front between the ironing mechanism 200 and the take-up roller 120, that is, the first guide roller 130 is located between the second guide roller 140 and the ironing mechanism 200. The height of the take-up roller 120, the first guide roller 130 and the second guide roller 140 decreases sequentially, so that the padding tape passing through the repair space 240 first passes around the upper side of the first guide roller 130, then passes around the lower side of the second guide roller 140, and is finally wound up at the take-up roller 120, so that the conveying of the padding tape is more stable and the winding of the padding tape is more regular.

[0058] It should be understood that in some other embodiments, the padding edge heating device also includes a rotary motor, which can drive the unwinding roller 110 and the take-up roller 120 to operate synchronously. That is, the padding edge heating device can automatically unwind and rewind the padding, that is, automatically transport the padding from back to front, which is beneficial to improving the efficiency of padding edge repair and ensuring the personal safety of users.

[0059] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that in this embodiment, the ironing mechanism 200 is detachably connected to the base plate 300 to adjust the distance between the two heating plates 210 to adapt to the repair use of pads of different widths, thereby improving the applicability of the pad ironing device to pads of different specifications.

[0060] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the base plate 300 is provided with two limiting plates 400, the two ends of the limiting plates 400 are arranged in the left and right direction, the support 230 is located between the two limiting plates 400, the two limiting plates 400 abut against the front end and the rear end of the support 230 respectively, and the support 230 is detachably connected to the limiting plates 400.

[0061] Reference Figure 1 , Figure 2 and Figure 3 As shown, an adjustment space is constructed between the two limiting plates 400, and the two supports 230 are both located within the adjustment space. By the two limiting plates 400 abutting against the front and rear ends of the supports 230 respectively, the movement of the supports 230 in the front-back direction can be restricted. After the heating edge mechanism 200 is separated from the base plate 300, the heating edge mechanism 200 can slide along the length direction of the limiting plate 400, thereby adjusting the distance between the two heating plates 210 to accommodate the use of pads of different widths. When the distance between the two heating plates 210 is adjusted to a suitable distance, the user can fix the relative positional relationship between the heating edge mechanism 200 and the limiting plate 400, that is, fix the distance between the two heating plates 210.

[0062] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the limiting plate 400 includes a first sub-plate 410 and a second sub-plate 420 arranged at right angles. The lower ends of the first sub-plate 410 and the second sub-plate 420 are connected. The first sub-plate 410 is connected to the base plate 300. The second sub-plate 420 can abut against the front end or the rear end of the support 230.

The lower end of the second sub-plate 420 is connected to the first sub-plate 410, so that the second sub-plate 420 extends upwards towards the base plate 300. The second sub-plate 420 can abut against the front or rear end of the support 230. Specifically, an adjustment space is constructed between the two first sub-plates 410, and the two second sub-plates 420 abut against the front or rear end of the support 230 respectively.

[0064] Reference Figure 1 , Figure 2 and Figure 3 As shown, the lower end of the support 230 can be detachably connected to the first sub-plate 410 and / or the second sub-plate 420 via a threaded connector, so as to realize the detachable connection between the support 230 and the base plate 300, so as to adjust the distance between the two supports 230, thereby adjusting the distance between the two heating plates 210.

[0065] Reference Figure 1 , Figure 2 and Figure 3 As shown, compared with traditional manual edge-ironing equipment or methods, the padding tape edge-ironing device provided in this embodiment of the utility model has at least the following beneficial effects:

[0066] (1) The heating plate 210 is fixedly connected to the heat-resistant component 220 and supported by the support 230. The conveyed pad is automatically heated by the two heating plates 210, so that the edge of the pad after being heated by the pad is smooth, neat, free of burrs, and durable.

[0067] (2) The hot edge repair mechanism 200 and the conveying mechanism 100 are used to achieve the hot edge repair of the pad, which can effectively improve the hot edge repair efficiency of the pad.

[0068] (3) Workers can maintain a safe distance from heat sources to ensure the safety of the operation and protect the personal safety of workers.
