Description

Technical Field

[0001] This utility model relates to the field of pipe feeding machine technology, and in particular to an automatic feeding device for a pipe feeding machine. Background Technology

[0002] In the pipe processing industry, semi-automatic pipe cutting machines typically require a feeding device to achieve continuous production. Traditional feeding methods rely heavily on overhead cranes, forklifts, or manual handling for pipe replenishment, resulting in high labor intensity, low efficiency, and significant safety hazards. While some feeding devices currently possess basic automation capabilities, the replenishment process still requires the use of overhead cranes, forklifts, or even manual handling, severely impacting the overall production efficiency and automation level of the pipe cutting machine. Utility Model Content

[0003] The purpose of this invention is to provide an automatic feeding device for pipe feeding machines to solve the problems existing in the prior art.

[0004] The purpose of this utility model is achieved as follows: An automatic feeding device for a pipe feeding machine is installed on the conveying trolley of the pipe feeding machine. It includes at least one set of inclined hydraulic cylinders, a toothed inclined top plate, and a guide rail synchronization device. The conveying trolley includes a movable support and a pipe tray installed on the top of the movable support. The pipe tray includes several support plates with serrated top surfaces. The front end of the support plate is connected to a downward slope. The toothed inclined top plate is installed on the lower side of the support plate and its bottom is connected to the piston rod of the inclined hydraulic cylinder. The body of the inclined hydraulic cylinder is installed on the movable support. The guide rail synchronization device is installed between the toothed inclined top plate and the movable support.

[0005] This utility model's automatic feeding device for pipe feeding machines integrates a slanted hydraulic cylinder, a toothed slanted top plate, and a guide rail synchronization device onto a conveying trolley. Combined with a sawtooth-shaped material support plate and a downward sloping structure, it achieves automatic lifting, orderly sliding, and precise positioning of pipes, effectively improving feeding efficiency and stability while reducing manual intervention and operational risks.

[0006] The automatic material replenishment device for the pipe feeding machine of this utility model has the following material replenishment process: (1) The piston rod of the inclined hydraulic cylinder extends and pushes the toothed inclined top plate to move upward and obliquely. The guide rail synchronization device ensures the smoothness of the movement. (2) The toothed inclined top plate moves up until the tooth surface contacts the bottom surface of the pipe and continues to move upward, pushing the pipe upward until the upper tooth surface at the front end of the toothed inclined top plate and the lower slope of the support plate are on the same inclined plane. At this time, the first pipe at the front end slides down the lower slope onto the conveyor frame. During this process, the remaining pipes slide into the tooth groove of the toothed inclined top plate. (3) The piston rod of the inclined hydraulic cylinder retracts, causing the toothed inclined top plate to move down. When it reaches a certain position, the bottom surface of the pipe contacts the toothed surface of the support plate. The toothed inclined top plate continues to move down, and the pipe slides into the toothed groove of the support plate. At this time, the pipe that has not been replenished is successfully moved forward one tooth on the support plate so that it can be replenished again.

[0007] The above is a feeding process. By repeating this action multiple times, the entire material on the support plate can be transported to the conveyor frame, realizing automatic material replenishment of the semi-automatic pipe cutting machine's feeding device.

[0008] As a further improvement of this utility model, the guide rail synchronization device includes an inclined guide rail mounted on a movable support, a slider mounted inside the toothed inclined top plate, and a reinforcing square tube mounted outside the toothed inclined top plate. The coordination between the inclined guide rail, the slider, and the reinforcing square tube enhances the synchronization and structural rigidity of the toothed inclined top plate during movement.

[0009] As a further improvement of this utility model, the guide rail synchronization device is set on both sides of the inclined hydraulic cylinder, which further improves the balance and stability of the lifting process.

[0010] As a further improvement of this utility model, the square tube, toothed inclined top plate and slider are connected by detachable parts, which facilitates maintenance and component replacement and improves the maintainability of the equipment.

[0011] As a further improvement of this utility model, the inclined hydraulic cylinder, the toothed inclined top plate, and the guide rail synchronization device are comprised of two sets, symmetrically arranged on both sides of the material support plate, and the toothed inclined top plates of the two sets have different tooth shapes. By symmetrically arranging the two toothed inclined top plates, universal adaptability to pipes of different specifications is achieved.

[0012] As a further improvement of this utility model, the pipe feeding machine also includes a pipe conveying frame, which is set at the front end of the pipe conveying trolley. By setting the pipe conveying frame, the smooth transition and continuous conveying of pipes from the feeding trolley to the pipe cutting machine is ensured. Attached Figure Description

Detailed Implementation

[0018] like Figure 1-4 The automatic feeding device for the pipe feeding machine shown is installed on the conveying trolley of the pipe feeding machine and includes two sets of inclined hydraulic cylinders 1, toothed inclined top plate 2 and guide rail synchronization device 3.

[0019] Specifically, the conveying trolley includes a movable support 4 and a pipe pallet 5 mounted on top of the movable support 4. The pipe pallet 5 includes several support plates 5A with serrated top surfaces, and the front end of each support plate 5A is connected to a downward ramp 5B. The pipe pallet 5 adopts an integral structure, which can be replaced as a whole when the type of pipe to be conveyed changes, thereby improving production changeover efficiency.

[0020] Two sets of inclined hydraulic cylinders 1, toothed inclined top plates 2, and guide rail synchronization devices 3 are symmetrically arranged on both sides of the material support plate 5A. The toothed inclined top plates 2 have different tooth shapes, achieving universal adaptability to pipes of different specifications. Specifically, the toothed inclined top plates 2 are located on the lower side of the material support plate 5A and their bottoms are connected to the piston rods of the inclined hydraulic cylinders 1. The bodies of the inclined hydraulic cylinders 1 are mounted on the movable support 4, and the guide rail synchronization devices 3 are located between the toothed inclined top plates 2 and the movable support 4.

[0021] like Figure 4 As shown, the guide rail synchronization device 3 includes an inclined guide rail 3A mounted on the movable support 4, a slider 3B mounted inside the toothed inclined top plate 2, and a reinforcing square tube 3C mounted outside the toothed inclined top plate 2. The inclined guide rail 3A, slider 3B, and reinforcing square tube 3C work together to enhance the synchronization and structural rigidity of the toothed inclined top plate 2 during movement. The reinforcing square tube 3C, toothed inclined top plate 2, and slider 3B are connected by detachable parts, facilitating maintenance and component replacement, and improving the maintainability of the equipment. The guide rail synchronization device 3 is located on both sides of the inclined hydraulic cylinder 1, further enhancing the balance and stability of the lifting process.

[0022] The pipe feeding machine also includes a pipe conveying frame 6, which is set at the front end of the pipe conveying trolley. By setting the pipe conveying frame 6, the smooth transition and continuous conveying of pipes from the feeding trolley to the pipe cutting machine is ensured.

[0023] The automatic feeding device for the pipe feeding machine in this embodiment integrates the inclined hydraulic cylinder 1, the toothed inclined top plate 2, and the guide rail synchronization device 3 onto the conveying trolley. Combined with the sawtooth material support plate 5A and the downward slope 5B structure, it realizes the automatic lifting, orderly sliding, and precise positioning of the pipe, effectively improving the feeding efficiency and stability, and reducing manual intervention and operational risks.

[0024] like Figure 6-10 As shown in the figure, the automatic feeding device for the pipe feeding machine in this embodiment has the following feeding process: (1) The piston rod of the inclined hydraulic cylinder 1 extends out, pushing the toothed inclined top plate 2 to move upward and obliquely, and the guide rail synchronization device 3 ensures the smoothness of the movement; (2) The toothed inclined plate 2 moves up until the tooth surface contacts the bottom surface of the pipe and continues to move upward, pushing the pipe upward until the upper tooth surface at the front end of the toothed inclined plate 2 is on the same inclined plane as the lower slope 5B of the material support plate 5A. At this time, the first pipe at the front end slides down the lower slope 5B onto the conveyor frame. During this process, the remaining pipes slide into the tooth groove of the toothed inclined plate 2. (3) The piston rod of the inclined hydraulic cylinder 1 retracts, causing the toothed inclined top plate 2 to move down. When it reaches a certain position, the bottom surface of the pipe contacts the toothed surface of the support plate 5A. The toothed inclined top plate 2 continues to move down, and the pipe slides into the toothed groove of the support plate 5A. At this time, the pipe that has not been replenished is successfully moved forward one tooth on the support plate 5A so that it can be replenished again.

[0025] The above is a feeding process. By repeating this action multiple times, the entire 5A pipe on the pallet can be transported to the conveyor frame, realizing automatic feeding of the semi-automatic pipe cutting machine's feeding device.
