Description

Technical Field

[0001] This utility model relates to an automatic feeding structure. Background Technology

[0002] With the continuous development of modern industry and the rapid advancement of high technology, the pipe processing industry is also developing towards higher processing efficiency and higher processing precision. Therefore, the automatic feeding structure of steel pipes is constantly being updated and iterated.

[0003] However, existing automatic steel pipe feeding structures on the market have the following problems: First, the automatic feeding structure uses a vibratory feeder, inclined gravity slide, or simple push rod mechanism. When the pipe size is slightly different, the surface is oily, or slightly deformed, problems such as jamming, multiple pipes slipping down at the same time, or inability to effectively separate a single pipe may occur. Second, the automatic feeding structure only delivers the pipe to the approximate position and lacks strong and precise fixing at key processing points. This causes the pipe to easily swing, vibrate, or move axially when cut or under stress, seriously affecting processing accuracy. Third, during the waiting period for processing or unloading, the pipe that has reached the working position may roll or shift in the inclined groove due to equipment vibration or its own weight, resulting in positioning failure. Moreover, after one pipe is unloaded, subsequent pipes cannot be reliably replenished to the waiting position in a timely manner, leading to unstable processing cycle or interruption. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic feeding structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An automatic feeding structure includes a frame, several support plates vertically mounted on the frame and evenly distributed, support rollers mounted at both ends of the frame via brackets, a steel pipe passing through the support plates and supported by the support rollers, a pipe dropping control mechanism mounted on one side of the support plate, a pipe releasing mechanism and a pipe blocking cylinder mounted on the other side of the support plate, an upper pipe-pushing cylinder bolted to the bottom of the support plate near the pipe outlet end of the frame, and a lower pipe-pressing cylinder bolted to the top of the support plate near the pipe outlet end of the frame.

[0007] Preferably, a steel pipe storage rack is bolted to the back of the frame.

[0008] Preferably, several support plates evenly distributed on the frame are connected and supported by horizontal tubes.

[0009] Preferably, the support plate has an inclined pipe drop groove, and the end of the inclined pipe drop groove has a U-shaped support groove. The side of the support plate is fixedly installed with a pipe support plate by means of an L-shaped plate and bolts. The pipe support plate is located below the inclined pipe drop groove. The side of the support plate is also fixedly installed with a guide rail on the side of the support plate by means of an L-shaped plate and bolts. The guide rail is located above the inclined pipe drop groove.

[0010] Preferably, the pipe lowering control mechanism includes an assembly horizontal plate fixedly mounted on the top of the support plate by bolts, a lifting cylinder fixedly mounted on the assembly horizontal plate and having its output end passing through the assembly horizontal plate, a lifting plate fixedly mounted to the output end of the lifting cylinder and having a slider welded on its inner side, and a first pipe body fixing cylinder and a second pipe body fixing cylinder fixed to both ends of the lifting plate by bolts.

[0011] Preferably, the pipe-laying mechanism includes a material-laying telescopic cylinder that is hinged to the cylinder base and the support plate, and an L-shaped pipe-stopping frame that is hinged to the output end of the material-laying telescopic cylinder at the right angle. One end of the L-shaped pipe-stopping frame is hinged to the support plate.

[0012] Preferably, the output end of the pipe-blocking cylinder is positioned upwards.

[0013] Preferably, the structure of the upper tube cylinder is the same as that of the lower tube cylinder.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By precisely blocking the second pipe body fixing cylinder and relaying the pipe blocking cylinder in the pipe dropping control mechanism, combined with the precise release of the pipe releasing mechanism, reliable single pipe separation and orderly dropping are achieved, effectively preventing jamming and continuous slippage.

[0016] 2. An upper tube-lifting cylinder and a lower tube-pressing cylinder are installed near the tube outlet end of the frame to form a strong vertical clamping force. Combined with the positioning of the U-shaped tube slot, the tube can be firmly and stably stabilized during processing, greatly reducing swaying and vibration, improving processing accuracy and safety. In addition, several support plates are distributed at equal intervals and connected by horizontal tubes to form multi-point, high-rigidity support. Furthermore, the support rollers provide support at both ends, which can effectively support the long tube, maintain its straightness and stability, and prevent deformation and shaking caused by its own weight or external forces.

[0017] 3. The pipe-laying mechanism precisely controls the opening and closing of the L-shaped pipe-blocking frame through the material-laying telescopic cylinder. It only releases the pipe in a controllable and precise manner after the first pipe-body fixing cylinder is released and the pipe-blocking cylinder ensures that the subsequent pipe is blocked. The whole process has a clear logic, a high degree of automation, and reduces the reliance on manual labor.

[0018] 4. A clamping combination of a first pipe-fixing cylinder and a pipe support plate is set at the lower end of the inclined pipe drop trough. During the waiting period for the pipe release command, the clamping mechanism can reliably fix the pipe to be processed, ensuring that it remains stationary in the correct position. The coordinated work of the pipe-blocking cylinder, the pipe release mechanism, and the pipe drop control mechanism is key. Furthermore, after the pipe is released, the pipe release mechanism resets to block the subsequent pipe, and at the same time, the pipe-blocking cylinder retracts, allowing the next pipe to immediately slide into the waiting position and be clamped by the first pipe-fixing cylinder, thus realizing a seamless and efficient continuous feeding cycle.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0024] Example

[0025] An automatic feeding structure, such as Figure 1-4 As shown, the system includes a frame 1, several support plates 2 vertically mounted on the frame 1 and evenly distributed, support rollers 3 mounted at both ends of the frame 1 via brackets, steel pipes 4 passing through the support plates 2 and supported by the support rollers 3, a pipe dropping control mechanism 5 mounted on one side of the support plate 2, a pipe releasing mechanism 6 and a pipe blocking cylinder 7 mounted on the other side of the support plate 2, an upper pipe-pushing cylinder 8 bolted to the bottom of the support plate near the pipe outlet end of the frame 1, and a lower pipe-pressing cylinder 9 bolted to the top of the support plate near the pipe outlet end of the frame 1.

[0026] In this embodiment, a steel pipe storage rack 11 is fixedly installed on the back side of the frame 1 by bolts.

[0027] Several support plates 2, which are equidistantly distributed on the frame 1, are connected and supported by horizontal tubes, forming a multi-point, high-rigidity support that can improve the structural stability of the support plates 2.

[0028] An inclined pipe drop groove 21 is provided on the support plate 2, and a U-shaped support groove 22 is provided at the end of the inclined pipe drop groove 21. A pipe support plate 23 is fixedly installed on the side of the support plate 2 by means of an L-shaped plate and bolts. The pipe support plate 23 is located below the inclined pipe drop groove 21. A guide rail 24 is also fixedly installed on the side of the support plate 2 by means of an L-shaped plate and bolts. The guide rail 24 is located above the inclined pipe drop groove 21.

[0029] The pipe-dropping control mechanism 5 includes an assembly horizontal plate 51 fixedly mounted on the top of the support plate 2 by bolts, a lifting cylinder 52 fixedly mounted on the assembly horizontal plate 51 with its output end passing through the assembly horizontal plate 51, a lifting plate 53 fixedly mounted to the output end of the lifting cylinder 52 with a slider welded on its inner side, a first pipe-body fixing cylinder 54 and a second pipe-body fixing cylinder 55 fixed to both ends of the lifting plate 53 by bolts, and the slider on the lifting plate 53 is assembled with the guide rail 24. When the lifting cylinder 52 drives the lifting plate 53 to move up and down, the lifting plate 53 can move stably close to the support plate 2. At the same time, the output end of the first pipe-body fixing cylinder 54 faces downward, which can cooperate with the pipe support plate 23 to clamp the steel pipe entering the inclined pipe-dropping groove 21, while the output end of the second pipe-body fixing cylinder 55 faces the inlet of the inclined pipe-dropping groove 21, which can prevent the steel pipe in the steel pipe storage rack 11 from entering the inclined pipe-dropping groove 21.

[0030] The pipe-laying mechanism 6 includes a discharge telescopic cylinder 61 hinged to the cylinder base and the support plate 2, and an L-shaped pipe-stopping frame 62 hinged to the output end of the discharge telescopic cylinder 61 at the right angle. One end of the L-shaped pipe-stopping frame 62 is hinged to the support plate 2. Specifically, when pipe laying is required, the first pipe-fixing cylinder 54 retracts and no longer squeezes and fixes the steel pipe. Then, the discharge telescopic cylinder 61 retracts and pulls the L-shaped pipe-stopping frame 62 downward. At this time, the steel pipe can fall smoothly into the U-shaped support groove 22 to complete the feeding, which facilitates the steel pipe to be processed in the next step along the U-shaped support groove 22.

[0031] The output end of the pipe-blocking cylinder 7 is set upward. Specifically, the pipe-blocking cylinder 7 is fixed to the upper end of the inclined pipe-dropping trough 21 by bolts, and the output end of the pipe-blocking cylinder 7 extends into the inclined pipe-dropping trough 21. The function of the pipe-blocking cylinder 7 is to block the steel pipe after it enters the inclined pipe-dropping trough 21. After the pipe-releasing mechanism 6 completes the pipe-releasing reset, the output end of the pipe-blocking cylinder 7 will retract, so that the next steel pipe can fall into the lower end of the inclined pipe-dropping trough 21, and the pipe-releasing mechanism 6 will block the waiting material feeding work again.

[0032] It should be further explained that the coordinated operation of the pipe-blocking cylinder 7, the pipe-releasing mechanism 6, and the pipe-dropping control mechanism 5 is crucial. After the pipe is released, the pipe-releasing mechanism resets to block subsequent pipes, while the pipe-blocking cylinder retracts, allowing the next pipe to immediately slide into the waiting position and be clamped by the first pipe-body fixing cylinder 54, achieving a seamless and efficient continuous feeding cycle. Moreover, through the precise blocking of the second pipe-body fixing cylinder 55 in the pipe-dropping control mechanism 5 and the relay control of the pipe-blocking cylinder 7, combined with the precise release of the pipe-releasing mechanism 6, reliable single-pipe separation and orderly falling are achieved, effectively preventing jamming and continuous slippage.

[0033] In this embodiment, the structure of the upper tube cylinder 8 is the same as that of the lower tube cylinder 9.

[0034] It should be further explained that, in actual operation, the upper tube-mounting cylinder 8 and the lower tube-mounting cylinder 9 form a strong vertical clamping force on the steel pipe. With the positioning of the U-shaped support groove 22, the pipe can be firmly and stably stabilized during processing, greatly reducing swinging and vibration, and improving processing accuracy and safety.

[0035] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
