Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pipe sandblasting equipment, specifically to a feeding mechanism for a sandblasting machine used in the production of small pipe fittings. Background Technology
[0002] Sandblasting is a very common surface treatment process in pipe fitting manufacturing. This process effectively removes impurities such as rust and oxide scale from the surface of pipe fittings by spraying sand particles at high speed, significantly improving the surface quality of the pipe fittings.
[0003] Existing sandblasting machines typically use conveyor rollers for feeding pipes. This method ensures stable feeding for pipes with larger diameters or longer lengths. However, for smaller pipes, the relatively large gap between the conveyor rollers leads to uneven feeding, severely impacting sandblasting efficiency and quality. Therefore, it is necessary to improve the feeding mechanism of existing sandblasting machines to solve the problem of uneven feeding of small pipes. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a feeding mechanism for a sandblasting machine used in the production of small pipe fittings, so as to solve the problem of poor feeding of small pipes by the existing conveyor roller feeding method, so as to ensure that small pipe fittings can be fed stably and smoothly, and improve sandblasting efficiency and quality.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.
[0006] A feeding mechanism for a sandblasting machine used for producing small pipe fittings includes a rotary roller conveying assembly. The rotary roller conveying assembly includes a horizontally arranged support frame, on which a plurality of conveying rollers are rotatably arranged at intervals along the length direction. It also includes a bottom support rail for placing the pipe fittings and moving on the conveying rollers under the drive of the rotary roller conveying assembly to achieve feeding. A guide component for guiding the bottom support rail is provided between the bottom support rail and the rotary roller conveying assembly.
[0007] Preferably, the bottom support fence is boat-shaped and has a mesh structure, including a mesh bottom plate, with mesh end plates that are obliquely upward and arc-shaped at the front and rear ends of the mesh bottom plate along the walking direction, and mesh side plates that are obliquely upward and arc-shaped at the left and right sides of the mesh bottom plate perpendicular to the walking direction; adjacent mesh side plates and mesh end plates are closedly connected.
[0008] Preferably, the mesh end plate is provided with a handle for easy movement of the bottom support railing.
[0009] Preferably, the guiding assembly includes two guide rails that are horizontally arranged along the length of the support frame and are arranged opposite to each other on the support frame, with the two guide rails located above both ends of the conveying roller; the guiding assembly also includes a guide groove that is horizontally arranged along the length of the mesh side plate on the outside of the mesh side plate and is adapted to the guide rails.
[0010] Preferably, the upper and lower sides of the guide groove are respectively provided with ball bearings for abutting against the guide rail along the length direction.
[0011] Preferably, the rotary conveyor assembly further includes a motor mounted on a support frame, and the motor is connected to each conveyor roller via a transmission assembly.
[0012] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.
[0013] This invention uses an added bottom support railing to wrap and support small pipe fittings, enabling smooth transport of these fittings on the conveyor rollers. This ensures stable feeding of the small pipe fittings and improves sandblasting efficiency and product quality. The guide rails, guide grooves, and ball bearings in the guide assembly effectively guide the movement of the bottom support railing, further enhancing its stability and accuracy, ensuring that the small pipe fittings accurately enter the sandblasting area. A handle on the bottom support railing facilitates easy movement by the operator. Attached Figure Description
[0014] Figure 1 This is a schematic diagram of the structure of this utility model;
[0015] Figure 2 This is a side view of the bottom support fence of this utility model.
[0016] The components are: 1. Roller conveyor assembly, 11. Support frame, 12. Conveyor roller, 13. Guide rail, 2. Bottom support rail, 21. Mesh bottom plate, 22. Mesh side plate, 23. Mesh end plate, 24. Guide groove, 25. Handle. Detailed Implementation
[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0018] A feeding mechanism for a sandblasting machine used in the production of small pipe fittings, combined with Figure 1 As shown, it includes a roller conveyor assembly 1 and a bottom support fence 2. The bottom support fence 2 is used to place pipes and to feed them under the drive of the roller conveyor assembly 1.
[0019] The rotary conveyor assembly 1 includes a horizontally arranged support frame 11, on which a plurality of conveyor rollers 12 are rotatably arranged at intervals along the length of the support frame 11. A bottom support rail 2 is placed on the conveyor rollers 12, and these conveyor rollers 12 are rotatable, providing basic conveying power for feeding the bottom support rail 2. In addition, the rotary conveyor assembly 1 also includes a motor mounted on the support frame 11. The motor is connected to each conveyor roller 12 via a transmission assembly (the transmission assembly is prior art and is not limited or described here; any common transmission method in the art, such as belt drive, chain drive, etc.), thereby enabling the motor to drive the conveyor rollers 12 to rotate and drive the bottom support rail 2 to move along the conveyor rollers 12.
[0020] like Figure 2 As shown, the bottom support fence 2 is boat-shaped and has a mesh structure. This shape and structure design can effectively adapt to small pipe fittings while ensuring that its own weight is reduced without affecting the support of the pipe fittings. Specifically, the bottom support fence 2 includes a mesh base plate 21, a mesh end plate 23, and a mesh side plate 22.
[0021] The mesh base plate 21 serves as the foundation of the bottom support fence 2 and is placed on the conveyor roller 12 to support the pipe fittings.
[0022] Mesh end plates 23 are disposed at the front and rear ends of the mesh base plate 21 along the travel direction, facing each other and angled upwards in an arc shape. Mesh side plates 22 are located on the left and right sides of the mesh base plate 21 perpendicular to the travel direction, facing each other and angled upwards in an arc shape. Adjacent mesh side plates 22 and mesh end plates 23 are closedly connected to form a relatively enclosed space, stably accommodating the pipe fittings and effectively enabling smooth feeding of small pipe fittings.
[0023] The mesh end plate 23 is equipped with a handle 25 for easy movement of the bottom support fence 2. When it is necessary to clean, repair or change the position of the bottom support fence 2, the staff can easily operate it through the handle 25.
[0024] A guide assembly is provided between the base support fence 2 and the roller conveyor assembly 1. The guide assembly guides the base support fence 2 to ensure that it moves along the conveying direction of the roller conveyor assembly 1. Specifically, the guide assembly includes two guide rails 13 and two guide grooves 24. The two guide rails 13 are horizontally arranged along the length of the support frame 11 and are positioned opposite each other on the support frame 11, with the two guide rails 13 located above both ends of the conveyor roller 12. The two guide grooves 24 are horizontally arranged along the length of the mesh side plates 22 on the outer side of the two mesh side plates 22 and are adapted to the guide rails 13. The guide grooves 24 cooperate with the guide rails 13 to ensure stable sliding of the base support fence 2 on the guide assembly and to ensure the stability of the base support fence 2's movement.
[0025] Ball bearings are rotatably mounted on the upper and lower sides of the guide groove 24 along its length. These ball bearings abut against the guide rail 13. The presence of the ball bearings greatly reduces the friction between the guide groove 24 and the guide rail 13, making the bottom support rail 2 move more smoothly. It also reduces wear between components and extends the service life of the guide assembly and the bottom support rail 2.
[0026] The working principle of this utility model is as follows:
[0027] Move the bottom support fence 2 and insert the guide grooves 24 on both sides of the bottom support fence 2 into the guide rails 13 on the support frame 11. Continue to move the bottom support fence 2 so that the bottom support fence 2 is completely placed on the conveying roller 12 initially conveyed by the roller conveyor assembly 1. Arrange the small pipes one by one neatly on the mesh bottom plate 21 of the bottom support fence 2 so that the bottom of the small pipes is located in the space formed by the mesh end plate 23 and the mesh side plate 22, and complete the feeding preparation work.
[0028] The motor in the drive roller conveyor assembly 1 rotates, driving each conveyor roller 12 to rotate via the transmission assembly. During rotation, the bottom support rail 2, placed on the conveyor roller 12, moves along the conveying direction. Simultaneously, due to the guiding effect of the guide assembly, the bottom support rail 2 moves stably on the conveyor roller 12, thus enabling the feeding of small pipe fittings. Furthermore, the feeding of small pipe fittings is smooth under the support of the bottom support rail 2.
