Description
Technical Field
[0001] This utility model relates to the technical field of sealing processing devices, specifically to a sealing processing device for the interface of a heat shrink sleeve for plastic products. Background Technology
[0002] In municipal pipeline systems such as urban water supply, drainage, and gas, plastic pipes of different diameters need to be connected. The heat shrink sleeve joint sealing processing device puts the heat shrink sleeve on the pipe connection part, and heats it to shrink it, tightly fitting the pipe interface to form a sealing structure and prevent liquid or gas leakage.
[0003] The existing technology has the following problems: Existing devices cannot automatically spray hot air around the heat shrink sleeve during use. Manual operation makes it difficult to ensure the uniformity of hot air spray around the heat shrink sleeve. Some areas may be overheated, causing the heat shrink sleeve to thin and its performance to deteriorate; while other areas may be underheated and unable to shrink fully. As a result, the interface between the heat shrink sleeve and the plastic product cannot fit tightly, leaving gaps and reducing sealing performance. In addition, existing devices cannot clean the filter plate at the air inlet. If the filter plate is not cleaned for a long time, a large amount of dust, debris and other impurities will accumulate. These impurities will adhere to the surface of the filter plate, obstructing airflow and reducing the amount of air entering the device to participate in the hot air spray. Insufficient hot air flow cannot effectively and evenly heat the heat shrink sleeve, resulting in uneven shrinkage of the heat shrink sleeve and affecting the sealing quality. Utility Model Content

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific implementation methods.
[0015] like Figure 1 As shown, this utility model provides a plastic product heat shrink sleeve interface sealing processing device, including a base 1, a fixing column 4 fixedly connected to the upper side of the base 1, and a first motor 5 fixedly connected to the upper side of the fixing column 4. The base 1 provides stable support for the entire device, and the fixing column 4 is vertically fixed to the upper side of the base 1, serving to connect and support other components. The first motor 5 is installed on the top of the fixing column 4, providing power for part of the device's movement. A fixing half ring 2 is fixedly connected to the upper side of the base 1, and a lifting half ring 3 is provided on the front side of the fixing column 4. Both ends of the fixing half ring 2 are movably connected to the lifting half ring 3. The fixing half ring 2 and the lifting half ring 3 together constitute a structure for fixing the pipe connection part and the heat shrink sleeve. The fixing half ring 2 is fixed on the base 1, and the lifting half ring 3 is located on the front side of the fixing column 4 with both ends movably connected to the fixing half ring 2. This structural design makes the lifting half ring 3 and the fixing half ring 2 form a complete ring, preparing for subsequent hot air blowing.
[0016] like Figure 2-3As shown, this utility model provides a technical solution: Preferably, a limiting groove 7 is provided on the opposite surfaces of the fixed half-ring 2 and the lifting half-ring 3; a half-tooth ring 8 is fixedly connected to the opposite surfaces of the fixed half-ring 2 and the lifting half-ring 3; a limiting strip 9 is slidably connected to the inner surface of the limiting groove 7; a connecting plate 10 is fixedly connected to the inner surface of the limiting strip 9; a fixing seat 6 is fixedly connected to the inner surface of the connecting plate 10; a lifting plate 12 is fixedly connected to the rear side of the lifting half-ring 3; a threaded column 11 is fixedly connected to the output end of the first motor 5; the outer wall of the threaded column 11 is rotatably connected to the fixing column 4; the outer wall of the threaded column 11 is threadedly connected to the lifting plate 12; the outer wall of the lifting plate 12 is slidably connected to the fixing column 4; a second motor 23 is fixedly connected to the lower side of the inner surface of the fixing seat 6; a gear 24 is fixedly connected to the output shaft of the second motor 23; the outer wall of the gear 24... The limiting groove 7 and the half-tooth ring 8, which are engaged and connected with the half-tooth ring 8, and the corresponding limiting strip 9, connecting plate 10 and fixing seat 6, together achieve the precise positioning and movement of the fixing seat 6 on the half-ring structure. The limiting strip 9 slides in the limiting groove 7 to ensure that the fixing seat 6 can only move in a specific direction, which enhances the stability of the structure. The second motor 23 in the fixing seat 6 drives the gear 24 to rotate. The gear 24 meshes with the half-tooth ring 8, so that the fixing seat 6 can make circumferential movements along the spliced ring structure. In this way, when the heating plate 25 in the fixing seat 6 works, it can automatically blow hot air around the heat shrink sleeve. By precisely controlling the operation of the second motor 23, the temperature, flow rate and blowing position and time of the hot air can be precisely controlled to ensure that the heat shrink sleeve is heated evenly.
[0017] like Figure 4-5As shown, this utility model provides a technical solution: Preferably, a support plate 13 is fixedly connected to the upper side of the fixed base 6, an electric telescopic rod 14 is fixedly connected to the right side of the support plate 13, a movable block 15 is fixedly connected to the output end of the electric telescopic rod 14, two rotating plates 16 are rotatably connected to the right side of the movable block 15, a cleaning plate 17 is rotatably connected to the other end of the rotating plate 16, two limiting plates 18 are fixedly connected to the upper side of the fixed base 6, the outer wall of the limiting plate 18 is slidably connected to the cleaning plate 17, an air inlet is opened on the upper side of the fixed base 6, a filter plate 21 is fixedly connected to the inner surface of the air inlet, the cleaning surface of the cleaning plate 17 is movably connected to the filter plate 21, a support plate 19 is fixedly connected to the lower side of the fixed base 6, a fan 20 is fixedly connected to the upper side of the support plate 19, the input pipe of the fan 20 is fixedly connected to the fixed base 6, multiple heating plates 25 are fixedly connected to the inner surface of the fixed base 6, a partition plate 22 is fixedly connected to the inner surface of the fixed base 6, and the support plate 13 on the upper side of the fixed base 6 is electrically telescopic. Rod 14 provides fixed support. When the electric telescopic rod 14 extends or retracts, it pushes the movable block 15 to move left and right. The movable block 15 is connected to the cleaning plate 17 through the rotating plate 16. When the movable block 15 moves, the rotating plate 16 drives the cleaning plate 17 to move linearly under the restriction of the limiting plate 18. The cleaning surface of the cleaning plate 17 contacts the filter plate 21 at the air inlet and cleans it. The support plate 19 is fixed on the lower side of the fixed base 6 and is used to install the fan 20. The fan 20 is connected to the fixed base 6 through the input pipe and draws outside air into the fixed base 6. After being filtered by the filter plate 21, it is heated by the heating plate 25 to form hot air, which blows onto the heat shrink sleeve. The partition plate 22 divides the interior of the fixed base 6, which helps to make the hot air flow and distribution reasonable. By periodically starting the electric telescopic rod 14, the cleaning plate 17 is driven to clean the filter plate 21, which can remove the dust, debris and other impurities accumulated on the filter plate 21 in time, ensuring a stable airflow into the device and providing a guarantee for uniform hot air blowing.
[0018] The working principle of the heat shrink sleeve interface sealing processing device for plastic products will be explained in detail below.
[0019] like Figure 1-5As shown, the limiting groove 7 and the semi-toothed ring 8 on the opposite surfaces of the fixed semi-ring 2 and the lifting semi-ring 3, along with the corresponding limiting strip 9, connecting plate 10, and fixed seat 6, together achieve the precise positioning and movement of the fixed seat 6 on the semi-ring structure. The limiting strip 9 slides within the limiting groove 7, ensuring that the fixed seat 6 can only move along a specific direction, thus enhancing the stability of the structure. The second motor 23 inside the fixed seat 6 drives the gear 24 to rotate, and the gear 24 meshes with the semi-toothed ring 8, enabling the fixed seat 6 to move in a circular motion along the spliced ring structure. Thus, when the heating plate 25 inside the fixed seat 6 is working, it can automatically spray hot air around the heat shrink sleeve. By precisely controlling the operation of the second motor 23, the temperature, flow rate, and spraying position and time of the hot air can be precisely controlled, ensuring that the heat shrink sleeve is heated evenly. The support plate 13 on the upper side of the fixed seat 6 provides fixed support for the electric telescopic rod 14, which extends or When shortening, the movable block 15 is pushed to move left and right. The movable block 15 is connected to the cleaning plate 17 through the rotating plate 16. When the movable block 15 moves, the rotating plate 16 drives the cleaning plate 17 to move in a straight line under the restriction of the limiting plate 18. The cleaning surface of the cleaning plate 17 contacts the filter plate 21 at the air inlet and cleans it. The support plate 19 is fixed on the lower side of the fixed base 6 and is used to install the fan 20. The fan 20 is connected to the fixed base 6 through the input pipe and draws outside air into the fixed base 6. After being filtered by the filter plate 21, it is heated by the heating plate 25 to form hot air, which blows the heat shrink sleeve. The partition plate 22 divides the interior of the fixed base 6, which helps the hot air to flow and distribute reasonably. By periodically starting the electric telescopic rod 14, the cleaning plate 17 is driven to clean the filter plate 21, which can remove the dust, debris and other impurities accumulated on the filter plate 21 in time, ensuring a stable airflow into the device and providing a guarantee for uniform hot air blowing.
