Description

Technical Field

[0001] This utility model relates to the technical field of pipe joint structure equipment, specifically a pipe joint coating equipment. Background Technology

[0002] In piping connection systems, pipe fittings are key components for achieving sealed pipe connections, and their surface protection directly affects the product's storage life, transportation safety, and subsequent installation reliability. To prevent pipe fittings from rusting or becoming contaminated due to contact with air, moisture, or impurities between the time they leave the factory and the time they are installed, the industry commonly uses a process of covering the surface of the pipe fittings with a thermoplastic film.

[0003] Currently, the application of heat-shrink film to pipe fittings largely relies on manual operation: operators first place the heat-shrink film over the pipe fitting, then use a handheld hot air device to heat the film, causing it to shrink and adhere tightly to the pipe fitting surface. However, this method has significant drawbacks: firstly, it is difficult to maintain consistent temperature, airflow, and heating angle during manual heating, leading to uneven shrinkage of the heat-shrink film, resulting in wrinkles, bubbles, or localized overheating and damage, affecting the protective effect and product appearance quality; secondly, manually processing each pipe fitting individually is inefficient, unsuitable for large-scale production, and prolonged operation can easily cause operator fatigue, further increasing the risk of quality fluctuations.

[0004] Furthermore, while some highly automated thermoplastic film covering equipment can improve efficiency, it is often complex in structure, including multiple drive motors, precision conveying mechanisms, and temperature control systems. This not only results in high manufacturing costs but also demands high skill levels from operators and presents significant maintenance challenges, making it unsuitable for the actual production scenarios of small and medium-sized manufacturing enterprises. Therefore, developing a pipe fitting processing device that is simple in structure, low in cost, and can achieve efficient and stable thermoplastic film covering has become a pressing technical problem for the industry. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a pipe joint coating device.

[0006] The technical solution adopted by this utility model is: a pipe joint coating device, including a support, a turntable, a positioning column, a fixing tooth column and a hot air device;

[0007] The positioning posts are multiple, spaced apart on the outer ring of the turntable and rotatably connected to the turntable. The upper end of the positioning post is provided with a connecting section for fitting a pipe fitting, and the lower end is provided with a driven toothed ring.

[0008] The fixed toothed column is fixed on the bracket, and a driving toothed ring is provided on the fixed toothed column. The driving toothed ring and the driven toothed ring are meshed and connected for transmission.

[0009] The air outlet of the hot air device is positioned opposite the positioning post on one side of the fixed toothed column, and is used to blow hot air onto the pipe joint on the positioning post.

[0010] Furthermore, the turntable is mounted on a support, and a drive mechanism for driving the turntable to rotate is provided at the bottom of the support.

[0011] Furthermore, the positioning posts are evenly spaced on the outer ring of the turntable.

[0012] Furthermore, the positioning column and the turntable are rotatably connected via bearings.

[0013] Furthermore, the driven gear ring is integrally formed on the outer wall of one end of the positioning post, and the driving gear ring is integrally formed on the outer wall of one end of the fixed gear post.

[0014] Furthermore, the hot air device is a hot air blower.

[0015] The beneficial effects of this utility model are:

[0016] 1. Improved coating quality: Through the meshing transmission of the active and driven gear rings, the positioning pins and pipe joints can rotate autonomously in the area of ​​the hot air device, so that all parts of the heat shrink film are heated and shrinked evenly, ensuring that the heat shrink film is tightly and flatly attached to the surface of the pipe joint, thus improving the product's protective effect and appearance quality.

[0017] 2. Improved production efficiency: The rotary structure enables continuous conveying and processing of pipe fittings, eliminating the need for manual handling of each fitting individually. This significantly shortens the coating cycle for a single pipe fitting, adapts to the needs of large-scale production, and substantially improves overall production efficiency.

[0018] 3. Reduced equipment costs and maintenance difficulty: The overall structure of the equipment is simple, mainly consisting of a support frame, turntable, positioning column, fixed gear column, and hot air device. It does not require complex multiple drive motors and precision control systems, resulting in low manufacturing costs. At the same time, the fewer parts and simpler connections reduce the difficulty of equipment maintenance and subsequent operating costs, making it particularly suitable for small and medium-sized manufacturing enterprises.

[0019] 4. Simplified operation process: Operators only need to put the pipe fitting into the connecting section of the positioning column and put on the heat shrink film. The subsequent conveying, rotation and heating processes are all completed automatically by the equipment, reducing manual intervention, lowering the skill level requirements of operators, helping to reduce human error and ensure production stability.

If the specific posture changes, the directional indicators will also change accordingly.

[0025] This utility model provides a pipe joint coating equipment.

[0026] In this embodiment, refer to Figure 1 The pipe joint coating equipment includes a support 1, a turntable 2, a positioning column 3, a fixing toothed column 4, and a hot air device 5;

[0027] The positioning posts are multiple, spaced apart on the outer ring of the turntable and rotatably connected to the turntable. The upper end of the positioning post is provided with a connecting section 6 for pipe fitting and connection, and the lower end is provided with a driven toothed ring 7.

[0028] The fixed toothed column is fixed on the bracket, and the fixed toothed column is provided with a driving toothed ring 8, which meshes with the driven toothed ring for transmission.

[0029] The air outlet of the hot air device is positioned opposite the positioning post on one side of the fixed toothed column, and is used to blow hot air onto the pipe joint on the positioning post.

[0030] The equipment described above consists of a support frame, a turntable, multiple positioning columns, fixed gear columns, and a hot air device. The positioning columns are spaced apart on the outer ring of the turntable and rotatably connected to it. The upper connecting section of each column is for fitting pipe fittings, and the lower end has a driven gear ring. The fixed gear columns are fixed to the support frame, and their driving gear rings mesh with the driven gear rings. The outlet of the hot air device faces the positioning column on one side of the fixed gear column. During operation, the pipe fitting is fitted onto the connecting section and covered with heat-shrink film. The turntable rotates, causing the positioning columns to move. When the positioning column reaches the side of the fixed gear column, the driving gear ring meshes with the driven gear ring, causing the positioning column and pipe fitting to rotate. The hot air device blows hot air onto the heat-shrink film on the pipe fitting, causing it to shrink and adhere.

[0031] This system achieves semi-automatic operation for coating pipe fittings. Through the rotation of positioning columns and the uniform blowing of hot air, it ensures even shrinkage of the heat-shrink film, improving coating quality. Its simple structure and coordinated operation of all components reduce equipment costs, increase coating efficiency, and meet the needs of mass production.

[0034] Specifically, the positioning posts are evenly spaced on the outer ring of the turntable.

[0035] In this embodiment, the positioning posts are evenly distributed on the outer ring of the turntable, so that the distance between adjacent positioning posts is consistent, and the time interval between each positioning post reaching the hot air device is uniform when the turntable rotates.

[0036] Specifically, the positioning column and the turntable are rotatably connected via bearings.

[0037] In this embodiment, the positioning column and the turntable are connected by a bearing. The bearing reduces the frictional resistance between the positioning column and the turntable when the positioning column rotates, allowing the positioning column to rotate flexibly and smoothly.

[0038] Specifically, the driven gear ring is integrally formed on the outer wall of one end of the positioning post, and the driving gear ring is integrally formed on the outer wall of one end of the fixed gear post.

[0039] In this embodiment, the driven gear ring is integrally formed on the outer wall of one end of the positioning post, and the driving gear ring is integrally formed on the outer wall of one end of the fixed gear post, which enhances the firmness of the connection between the gear ring and the post and ensures the stability and reliability of the meshing transmission.

[0040] Specifically, the hot air device is a hot air blower.

[0041] In this embodiment, the hot air device uses a hot air blower, which can generate stable hot air. The air outlet is directly opposite the pipe joint, which can accurately blow hot air onto the heat shrink film to meet the temperature conditions required for the heat shrink film to shrink.

[0042] Please note to all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
