[0002] At present, in the process of processing round tubes, a tube feeding device is needed to transport the tubes to the processing equipment to improve the feeding efficiency of the tubes.

[0003] The Chinese utility model patent with announcement number CN216807060U specifically discloses "a pipe feeding device", which stacks pipes on a placement mechanism. The pipes roll toward the feed end under the action of their own weight and enter the conveying mechanism from the feed end. The motor drives the conveying mechanism to transport the pipes from the bottom to the top to the discharge end at the upper end. There is no need for manual handling, so the automatic feeding of pipes is realized, thereby improving production efficiency.

[0004] However, in practical applications, sometimes multiple pipes enter the conveying mechanism at the same time, which affects the feeding of subsequent pipes and results in poor feeding effect of the pipes, so improvement is needed. Summary of the invention

[0006] The present application provides a pipe feeding device adopting the following technical solution: The lifting of the ...

[0007] By adopting the above technical scheme, in actual application, in the initial state, one of the first material receiving plates abuts against the baffle, so that the channel is in a blocked state; during operation, the two ends of multiple pipes are placed on the two placement plates, so that multiple pipes are stored in the two connecting plates, the two limit plates and the two placement plates, and the driving component drives the multiple material receiving components to move synchronously and at intervals, so that the multiple first material receiving plates move along the circumferential direction of the mounting frame. During this process, the first material receiving plate abutting against the baffle moves away from the baffle, and the baffle rotates and abuts against the next first material receiving plate under the action of the torsion spring, so that the channel is opened, and a single pipe falls into the next first material receiving plate under the guidance of the baffle, and the first material receiving plate continues to move when receiving the pipe to reset the baffle to the initial state to complete the material receiving work of the pipe once, so that it can ensure that only a single pipe enters the first material receiving plate, thereby improving the feeding effect of the pipe.

[0008] Preferably, the material receiving assembly further comprises a limit bar, wherein the limit bar is arranged at an end of the first material receiving plate away from the driving assembly and is arranged along the length direction of the first material receiving plate.

[0029] The following is combined with Figure 1-6 This application is described in further detail.

[0030] The embodiment of the present application discloses a pipe feeding device.

[0031] Reference Figure 1 The pipe feeding device includes a machine platform 1 and a conveying mechanism 2. The machine platform 1 includes a mounting frame 11 and a loading frame 12. The mounting frame 11 is vertically placed on the ground. The loading frame 12 includes a frame body 121 and two loading components 122. The frame body 121 is fixedly connected to one side of the mounting frame 11 and placed on the ground.

[0032] Reference Figure 1 and Figure 2 , wherein two feeding assemblies 122 are installed in the frame 121 at intervals, and specifically, the feeding assembly 122 comprises a connecting plate 122a, a limiting plate 122b, a placing plate 122c, a baffle 122d and a torsion spring 122e. The connecting plate 122a, the limiting plate 122b, the placing plate 122c and the baffle 122d are all rectangular in shape, the connecting plate 122a is fixedly connected to the upper end of the frame 121, the limiting plate 122b is vertically fixedly connected to the inner side of the connecting plate 122a near one end of the mounting frame 11, the placing plate 122c is obliquely fixedly connected to the inner side of the connecting plate 122a, and the lower end of the placing plate 122c is located directly below the limiting plate 122b and a channel 122f is formed between the placing plate 122c and the lower end of the limiting plate 122b for a single pipe to pass through. The baffle 122d is rotatably connected to the lower end of the placement plate 122c, and the torsion spring 122e is sleeved on the rotating shaft of the baffle 122d (not marked in the figure) and has one end fixedly connected to the baffle 122d and the other end fixedly connected to the placement plate 122c, so as to drive the baffle 122d away from the channel 122f, so that the channel 122f is in an open state.

[0033] Reference Figure 1 and Figure 3The conveying mechanism 2 includes a plurality of receiving components 21 and a driving component 22. The plurality of receiving components 21 are evenly spaced along the circumference of the mounting frame 11. The receiving component 21 includes a first receiving plate 211. The first receiving plate 211 is an "L"-shaped plate. One end of the first receiving plate 211 is fixedly connected to the driving component 22 and moves along the circumference of the mounting frame 11 to receive a single pipe passing through the channel 122f. It should be noted that one of the first receiving plates 211 abuts against the end of the baffle 122d away from the rotation to block the channel 122f, so that the channel 122f is in a closed state.

[0034] The driving assembly 22 includes a first transmission shaft 221, a second transmission shaft 222, two sprockets 223, a chain 224 and a servo motor 225. The first transmission shaft 221 and the second transmission shaft 222 are both rotatably connected to the mounting frame 11 and are arranged at intervals in the vertical direction. The two sprockets 223 are respectively fixedly connected to the first transmission shaft 221 and the second transmission shaft 222. The two ends of the chain 224 are respectively connected to the two sprockets 223. The servo motor 225 is fixedly connected to the mounting frame 11 and the power output shaft is fixed to the first transmission shaft 221. Among them, the first material receiving plate 211 is fixedly connected to the chain 224, and the servo motor 225 works intermittently to realize that the driving assembly 22 drives multiple material receiving assemblies 21 to move synchronously and at intervals. In this embodiment, the number of chains 224 is two, and the two chains 224 are arranged at intervals. Correspondingly, the number of sprockets 223 is four to ensure the stability of the installation and movement of the first material receiving plate 211.

[0035] Reference Figure 3 and Figure 4 In actual application, in the initial state, one of the first receiving plates 211 abuts against the end of the baffle 122d away from the rotation to block the channel 122f, so that the channel 122f is in a closed state to limit the pipe from passing through the channel 122f. During operation, the two ends of multiple pipes are placed on the two placement plates 122c, so that multiple pipes are stored in the two connecting plates 122a, the two limit plates 122b and the two placement plates 122c. The servo motor 225 works intermittently to drive the first transmission shaft 221 to rotate. Under the action of the second transmission shaft 222 and the two sprockets 223, the chain 224 is driven to drive the multiple first receiving plates 211 to move at intervals along the circumference of the mounting frame 11.

[0036] During the movement of multiple material receiving components 21, the first material receiving plate 211 abutting against the baffle 122d moves upward to move away from the baffle 122d. Under the action of the torsion spring 122e, the baffle 122d rotates to a tilted downward state (that is, the end of the baffle 122d away from the rotation is lower) and abuts against the next first material receiving plate 211, so that the channel 122f is opened, and a single pipe falls into the first material receiving plate 211 under the guidance of the baffle 122d. At the same time, the first material receiving plate 211 continues to move upward when receiving the pipe, so that the first material receiving plate 211 abuts against the end of the baffle 122d away from the rotation, so that the baffle 122d is reset to the initial state to complete the material receiving work of the pipe once. In this way, it can be ensured that only a single pipe enters the first material receiving plate 211, thereby improving the feeding effect of the pipe.

[0037] In some embodiments, the material receiving assembly 21 further includes a limiting bar 212, which is fixedly connected to one end of the first material receiving plate 211 away from the chain 224 and is arranged along the length direction of the first material receiving plate 211. Specifically, taking the first material receiving plate 211 abutting against the baffle 122d as an example, the limiting bar 212 is located on the upper side of the end of the first material receiving plate 211 away from the chain 224. When the pipe falls from the channel 122f to the first material receiving plate 211, the baffle 122d abuts against the upper side of the limiting bar 212, so that the pipe is limited between the first material receiving plate 211 and the limiting bar 212, and the pipe is prevented from being separated from the first material receiving plate 211 as much as possible, so as to ensure the stability of feeding, thereby further improving the feeding effect of the pipe.

[0038] In some embodiments, the material receiving assembly 21 further includes a plurality of springs 213, and the limit bar 212 is slidably connected to the first material receiving plate 211, and the sliding direction is perpendicular to the direction of the first material receiving plate 211 away from one end of the chain 224. One end of each spring 213 is fixedly connected to the limit bar 212, and the other end is fixedly connected to the first material receiving plate 211, so as to drive the limit bar 212 away from the first material receiving plate 211. In this way, when the pipe falls on the first material receiving plate 211, the pipe squeezes the limit bar 212, so that the limit bar 212 is close to the first material receiving plate 211, so that the pipe falls on the first material receiving plate 211. After the pipe moves to the first material receiving plate 211, the plurality of springs 213 drive the limit bar 212 away from the first material receiving plate 211, so as to ensure that the pipe can stably fall and be limited between the first material receiving plate 211 and the limit bar 212.

[0039] In some embodiments, the limit strip 212 is provided with a chamfer (not marked in the figure) on the side away from the spring 213 and close to the mounting frame 11. When the pipe falls on the first receiving plate 211, the pipe contacts the chamfer to squeeze the limit strip 212, thereby facilitating the pipe to fall between the first receiving plate 211 and the limit strip 212.

[0040] In some embodiments, the material receiving assembly 21 further includes a second material receiving plate 214, which is also an "L"-shaped plate, and the second material receiving plate 214 is arranged opposite to the first material receiving plate 211, so that the first material receiving plate 211 and the second material receiving plate 214 are linearly formed into a "concave" shape. The first material receiving plate 211 of one of the material receiving assemblies 21 abuts against the baffle 122d, and the second material receiving plate 214 of the material receiving assembly 21 located below it also abuts against the baffle 122d, so that the baffle 122d blocks the channel 122f more stably. More importantly, the material receiving assembly 21 located on the side close to the frame 121 moves to the other side after passing the upper end of the mounting frame 11. At this time, the upper and lower positions of the first material receiving plate 211 and the second material receiving plate 214 in the material receiving assembly 21 are interchanged, so that the pipe located on the first material receiving plate 211 falls onto the second material receiving plate 214, so that the pipe can be unloaded on the side of the mounting frame 11 away from the frame 121, thereby expanding the range of the pipe feeding position to be suitable for different pipe processing equipment.

[0041] In some embodiments, the material receiving assembly 21 further includes an extension plate 215, which is fixedly connected to one end of the second material receiving plate 214 away from the mounting frame 11, and the extension plate 215 extends away from the mounting frame 11 and close to the first material receiving plate 211, that is, the extension plate 215 is tilted and the end away from the second material receiving plate 214 is closer to the first material receiving plate 211. In addition, when the pipe in the first material receiving plate 211 falls into the second material receiving plate 214, the extension plate 215 can block the pipe to prevent the pipe from falling from the second material receiving plate 214, thereby further ensuring the stability of feeding and further improving the feeding effect of the pipe.

[0042] Reference Figure 1 and Figure 5 In some embodiments, the conveying mechanism 2 also includes an ejection assembly 23, which includes an ejection cylinder 231. The ejection cylinder 231 is fixedly connected to one side of the mounting frame 11 to push the pipe located in the second material receiving plate 214. At the same time, an ejection groove 111 is opened on the other side of the mounting frame 11 to push the pipe in the second material receiving plate 214, so that the pipe in the second material receiving plate 214 is pushed out from the ejection groove 111 to realize the feeding of the pipe.

[0043] In some embodiments, the ejection cylinder 231 is slidably connected to the mounting frame 11 along the vertical direction through a screw mechanism, and a clearance groove 112 is provided on the mounting frame 11 for the power output shaft of the ejection cylinder 231 to make way. At the same time, there are multiple ejection grooves 111, and the multiple ejection grooves 111 are evenly spaced along the vertical direction to realize feeding of pipes at different positions, so as to be suitable for different pipe processing equipment.

[0044] Reference Figure 5 and Figure 6 In some embodiments, the ejection assembly 23 also includes a sensor 232, which is fixedly connected to the power output shaft of the ejection cylinder 231. The sensor 232 is electrically connected to the ejection cylinder 231. The sensor 232 is used to detect whether there is a pipe in the corresponding second material receiving plate 214 to control the ejection cylinder 231 to work, so that the ejection cylinder 231 can accurately eject the pipe in the second material receiving plate 214.

[0045] In some embodiments, the ejection assembly 23 further includes a rubber pad 233, which is fixedly connected to the power output shaft of the ejection cylinder 231 to reduce the collision between the ejection cylinder 231 and the pipe, and to minimize the occurrence of pipe scratches and damage to the ejection cylinder 231. The sensor 232 is located in the rubber pad 233.

[0046] The implementation principle of this embodiment is as follows: in actual application, in the initial state, one of the first receiving plates 211 abuts against the end of the baffle 122d away from the rotation to block the channel 122f, so that the channel 122f is in a closed state to limit the pipe from passing through the channel 122f. During operation, the two ends of multiple pipes are placed on the two placement plates 122c, so that multiple pipes are stored in the two connecting plates 122a, the two limit plates 122b and the two placement plates 122c, and the servo motor 225 works intermittently to drive the first transmission shaft 221 to rotate. Under the action of the second transmission shaft 222 and the two sprockets 223, the chain 224 is driven to drive multiple first receiving plates 211 to move at intervals along the circumference of the mounting frame 11.

[0047] During the movement of multiple material receiving components 21, the first material receiving plate 211 abutting against the baffle 122d moves upward to move away from the baffle 122d. Under the action of the torsion spring 122e, the baffle 122d rotates to a tilted downward state (that is, the end of the baffle 122d away from the rotation is lower) and abuts against the next first material receiving plate 211, so that the channel 122f is opened, and a single pipe falls into the first material receiving plate 211 under the guidance of the baffle 122d. At the same time, the first material receiving plate 211 continues to move upward when receiving the pipe, so that the first material receiving plate 211 abuts against the end of the baffle 122d away from the rotation, so that the baffle 122d is reset to the initial state to complete the material receiving work of the pipe once. In this way, it can be ensured that only a single pipe enters the first material receiving plate 211, thereby improving the feeding effect of the pipe.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
