Description

Technical Field

[0001] This utility model belongs to the field of pipe fitting conveying technology, and in particular to a pipe fitting conveying mechanism for a marking device. Background Technology

[0002] To record the manufacturing information of the pipe fittings for later tracking, a coding device is installed on the pipe fitting conveyor belt. In the existing technology, the coding operation of the pipe fittings is completed manually in conjunction with the corresponding equipment. The specific method is as follows: the pipe fittings that have not been coded are placed on one side of the conveyor belt through a collection box. The operator at the conveyor belt places the pipe fittings in the collection box in front of the coding device. The sensor transmits the sensing signal to the coding device, and the coding device sprays ink onto the pipe fittings to complete the coding work. After that, the coded pipe fittings are placed on the conveyor belt and transported away for packaging.

[0003] Currently, a pipe fitting inkjet printing device [Authorization Announcement No.: CN209889794U] has been disclosed on the China Patent Network. It includes a first frame, a first conveying device on the first frame, an inkjet printing device fixedly mounted above the first conveying device, and the inkjet printing device fixedly mounted on the first frame. A second frame is fixedly mounted on the right side of the first frame, and a second conveying device is mounted on the second frame. The left side of the second conveying device extends to the upper right side of the first conveying device. A baffle is provided at the upper left end of the second conveying device. The baffle is fixedly mounted on the second frame through a connecting plate. A gap is provided between the bottom of the baffle and the top of the second conveying device. During operation, the operator is positioned corresponding to the coding device. The first conveyor belt is in continuous motion, while the second conveyor belt moves intermittently. The second conveyor belt transports the pipes produced in the previous process to the left. The pipes are blocked by baffles. When a certain number of pipes have accumulated, the second conveyor belt stops moving. In this way, all the pipes to be coded are always in a fixed area corresponding to the operator. The operator can directly take the pipes on the left side of the second conveyor belt to the coding device for coding, and then place the pipes on the first conveyor belt.

[0004] The above-mentioned pipe marking device has the following defects: the pipe is conveyed by a conveyor belt, and the surface of the conveyor belt is smooth. During the conveying process, the pipe cannot be accurately positioned, and the pipe is prone to slipping on the conveyor belt, making it impossible for the pipe to maintain a balanced state, which affects the subsequent marking operation of the pipe. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a pipe fitting conveying mechanism for a marking device. The technical problem to be solved by this utility model is: how to solve the problem of pipe fittings easily shifting during the existing pipe fitting conveying process.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A pipe conveying mechanism for a marking device is characterized in that it includes a drive shaft, a driven shaft, and a plurality of conveying components spaced apart along the axial direction of the drive shaft. Each conveying component includes two bushings, one bushing being fitted onto the drive shaft and the other bushing being fitted onto the driven shaft. Each bushing is fitted with a pulley, and a belt is fitted onto the two pulleys. The conveying surface of the belt has a positioning groove that is opened laterally. There are a plurality of positioning grooves, and all positioning grooves are spaced apart along the circumferential direction of the belt.

[0008] The pipe fitting is placed in the positioning groove along the axial direction of the drive shaft. Due to the long length of the pipe fitting, multiple conveying components are supported at different positions on the pipe fitting. The positioning groove on each conveying component limits the pipe fitting. Multiple positioning grooves limit multiple positions of the pipe fitting to ensure that the pipe fitting does not shift during the conveying process. The pipe fitting is always set in the axial direction along the drive shaft. After the drive shaft rotates, it drives the belt to rotate, thereby conveying the pipe fitting along the length of the belt. The large number of positioning grooves allows the belt to convey several pipe fittings at the same time, ensuring good pipe fitting conveying efficiency.

[0009] In the pipe conveying mechanism of the aforementioned marking device, the conveying assembly further includes a mounting plate. Both ends of the mounting plate are respectively fitted onto two bushings. A support plate is fixed to one side wall of the upper end of the mounting plate. The support plate is elongated and longitudinally positioned below the belt, abutting against the lower surface of the belt's upper portion. This structure provides support to the belt, preventing downward deformation during pipe conveying and ensuring smooth pipe transport.

[0010] In the pipe conveying mechanism of the aforementioned marking device, a vertically oriented mounting groove is provided in the middle of the mounting plate. A positioning block is provided in the mounting groove, and a rotating shaft is mounted on the lower end of the positioning block. A tensioning wheel is sleeved on the rotating shaft, and the outer circumferential surface of the tensioning wheel is in close contact with the inner surface of the lower part of the belt. A threaded hole communicating with the mounting groove is provided on the upper surface of the mounting plate, and a spring is provided in the mounting groove. The lower end of the spring abuts against the upper surface of the positioning block, and the upper end of the spring extends into the threaded hole. A plug for compressing the spring is screwed into the threaded hole. Through this structure, the outer circumferential surface of the tensioning wheel is in close contact with the inner surface of the lower part of the belt, thereby achieving belt tension. The rotatable plug can change the force of the spring seat positioning block, thus changing the force exerted by the tensioning wheel on the belt.

[0011] In the pipe conveying mechanism of the above-mentioned marking device, the positioning groove is a V-shaped groove, and each V-shaped groove has a guide surface with a smooth transition on one of its upper edges.

[0012] Compared with the prior art, the automotive metal pipe marking device of this utility model has the following advantages: This structure places the pipe in the positioning groove along the axial direction of the drive shaft. Due to the long length of the pipe, multiple conveying components are supported at different positions of the pipe. The positioning groove on each conveying component limits the pipe. Multiple positioning grooves limit multiple positions of the pipe, ensuring that the pipe does not shift during the conveying process. The pipe is always in the axial setting state along the drive shaft. After the drive shaft rotates, it drives the belt to rotate, thereby conveying the pipe along the length direction of the belt. The large number of positioning grooves allows the belt to convey several pipes at the same time, ensuring good pipe conveying efficiency. Attached Figure Description

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figures 1-4As shown, the pipe conveying mechanism of this marking device includes a drive shaft 1, a driven shaft 2, and several conveying components 3 arranged axially at intervals along the drive shaft 1. Each conveying component 3 includes two bushings 30, one bushing 30 being fitted onto the drive shaft 1 and the other bushing 30 being fitted onto the driven shaft 2. Each bushing 30 is fitted with a pulley 31, and a belt 32 is fitted onto the two pulleys 31. The conveying surface of the belt 32 has a positioning groove 4 opened laterally. There are several positioning grooves 4, and all positioning grooves 4 are arranged at intervals along the wrapping direction of the belt. The pipe fitting is placed in the positioning groove 4 along the axial direction of the drive shaft 1. Due to the long length of the pipe fitting, multiple conveying components 3 are supported at different positions on the pipe fitting. The positioning groove on each conveying component 3 limits the pipe fitting. Multiple positioning grooves 4 limit multiple positions of the pipe fitting to ensure that the pipe fitting does not shift during the conveying process. The pipe fitting is always set in the axial direction along the drive shaft 1. After the drive shaft 1 rotates, it drives the belt 32 to rotate, thereby conveying the pipe fitting along the length direction of the belt 32. The large number of positioning grooves 4 allows the belt 32 to convey several pipe fittings at the same time, ensuring good pipe fitting conveying efficiency.

[0021] like Figures 2-4 As shown, the conveying assembly 3 also includes a mounting plate 33. Both ends of the mounting plate 33 are respectively fitted onto two bushings 30. A support plate 34 is fixed to one side wall of the upper end of the mounting plate 33. The support plate 34 is elongated and longitudinally positioned below the belt 32 and abuts against the lower surface of the upper part of the belt 32. The support plate 34 provides support to the belt 32, preventing it from deforming downwards during the conveying of the pipe fittings and ensuring stable conveying of the pipe fittings.

[0022] like Figures 2-4 As shown, a vertically oriented mounting groove 330 is provided in the middle of the mounting plate 33. A positioning block 39 is provided in the mounting groove 330, and a rotating shaft 35 is installed at the lower end of the positioning block 39. A tensioning wheel 36 is sleeved on the rotating shaft 35. The outer circumferential surface of the tensioning wheel 36 is in close contact with the inner surface of the lower part of the belt 32. A threaded hole 331 communicating with the mounting groove 330 is provided on the upper surface of the mounting plate 333. A spring 37 is provided in the mounting groove 330. The lower end of the spring 37 abuts against the upper surface of the positioning block 39, and the upper end of the spring 37 extends into the threaded hole 331. A plug 38 for pressing the spring 37 is screwed into the threaded hole 331. The outer circumferential surface of the tensioning wheel 36 is in close contact with the inner surface of the lower part of the belt 32 to achieve belt tension. The rotatable plug 38 can change the force of the spring 37 on the positioning block 39, thereby changing the force of the tensioning wheel 36 on the belt 32.

[0023] like Figure 5 and Figure 6As shown, the positioning groove 4 is a V-shaped groove, and each V-shaped groove has a guide surface 40 with a smooth transition on one upper edge. During the rotation of the belt 32, the guide surface 40 expands the opening of the positioning groove 4, which is conducive to the quick placement of the pipe into the positioning groove. On the other hand, during unloading, the pipe automatically slides out of the positioning groove 4 along the guide surface 40.
