Description

Technical Field

[0001] The present application belongs to the technical field of laser cutting equipment, and specifically relates to a pipe feeding device. Background Art

[0002] Laser tube cutting machines have the advantages of high cutting accuracy, fast cutting speed, and high cutting surface quality, and have gradually replaced traditional tube cutting equipment. The tube cutting machine includes a tube cutting machine body and an automatic feeding device arranged on one side of the tube cutting machine body. The automatic feeding device is used to feed and divide the tubes to reduce the workload of the staff and improve the cutting efficiency of the tube cutting machine.

[0003] Common feeding devices generally use different forms of chains to transport pipes. Since the chain transportation method of pipes requires a reduction motor or servo motor to drive the chain to complete actions such as material distribution and feeding, and requires an independent control system, the cost of the feeding device is high and the control logic is complex. In addition, when feeding small pipes, due to the small cross-sectional size of small pipes, the distance between the central axes of two adjacent pipes is small, which increases the difficulty of dividing small pipes, and thus leads to a low success rate of feeding small pipes. Utility Model Content

[0004] The present application provides a pipe feeding device to reduce the production cost of the feeding device, simplify the control logic, and improve the feeding success rate of small pipes.

[0005] The technical solution adopted in this application is:

[0006] A pipe feeding device comprises at least two groups of feeding mechanisms, the feeding mechanism comprising a frame, a pushing assembly arranged on the frame and a pushing arm located at one end of the frame, a plurality of pipe storage positions are sequentially arranged on the top of the frame along a direction approaching or away from the pushing arm, the pushing assembly comprises a lifting and pushing rod and a telescopic driving member acting on the lifting and pushing rod, a plurality of pipe pushing positions are arranged on the top of the lifting and pushing rod corresponding to the pipe storage positions, when the telescopic driving member is extended, the pipe pushing position lifts and transports the pipe so that the pipe advances a distance of one pipe storage position in a direction approaching the pushing arm, and the frame is provided with a telescopic power member acting on the pushing arm so that the pushing arm has a feeding state moving in a direction away from the frame and a retracted state moving in a direction approaching the frame.

[0007] By adopting the above technical scheme, when loading pipes, multiple pipes are first placed in multiple pipe storage positions respectively, and then the telescopic driving member is started to drive the lifting and pushing rod. The pipe pushing position on the lifting and pushing rod contacts the pipe and lifts the pipe, and at the same time, all pipes are advanced toward the direction where the pushing arm is located by the distance of a pipe storage position, that is, the pipe close to the pushing arm moves to the pushing arm, and other pipes move forward to the next pipe storage position, and then the telescopic power member is started, and the telescopic power member drives the pushing arm to move toward the feeding state, that is, the pushing arm drives the pipe on its upper part to move in the direction away from the frame and move to above the lifting mechanism of the cutting machine body, and the lifting mechanism rises and lifts the pipe to complete the loading action.

[0008] Since the present application adopts a telescopic drive member and a telescopic power member, the use of a servo motor and a reduction motor is avoided, the cost of the pipe feeding device is reduced, and the control logic of the pipe feeding device is simplified, and the stability of the pipe feeding device is increased. In addition, the present application is provided with multiple pipe storage positions and multiple pipe pushing positions to realize the separate storage and separate transportation of multiple pipes, avoiding the adjacent pipes from conflicting with each other, resulting in greater difficulty in dividing the materials, thereby improving the feeding success rate of the pipe feeding device.

[0009] Optionally, a positioning plate is detachably connected to the top of the frame, and the positioning plate is sequentially provided with a plurality of positioning notches along a direction approaching or away from the pushing arm, and the positioning notches form the pipe storage position;

[0010] And / or, the top of the lifting and pushing rod is detachably connected to a limiting plate, and the limiting plate is sequentially provided with a plurality of limiting notches along a direction approaching or away from the pushing arm, and the limiting notches form the pipe pushing position.

[0011] By adopting the above technical solution, when using the pipe feeding device in the present application, you can choose to replace the appropriate positioning plate according to the cross-sectional size of the pipe. For example, when the cross-sectional size of the pipe is small, you can replace the positioning plate with a smaller pipe storage position to increase the number of pipe storage positions on the positioning plate, so as to reduce the number of times the staff needs to load materials, reduce the workload of the staff, improve the loading efficiency of the pipe feeding device, and improve the cutting efficiency of the pipe cutting machine equipped with the pipe feeding device. At the same time, the positioning notch on the positioning plate forms a pipe storage position, which can increase the structural strength of the pipe storage position while reducing the production cost of the pipe feeding device, so as to reduce the distance between adjacent pipe storage positions, and to arrange as many pipe storage positions as possible on the rack of the same length.

[0012] When using the pipe feeding device in the present application, you can choose to replace the limit plates with the same number of pipe pushing positions as the pipe storage positions according to the number of pipe storage positions, so as to reduce the number of times the limit plates are needed to transport the pipes, reduce the energy consumption of the pipe feeding device, and thus achieve energy-saving effects. At the same time, the control logic can be further simplified to reduce control costs and reduce the production costs of the pipe feeding device.

[0013] Optionally, the extension direction of the telescopic driving member is from bottom to top and tilted toward the pushing arm;

[0014] Alternatively, the telescopic driving member includes a vertical driving member and a horizontal driving member, the vertical driving member is used to drive the lifting and pushing rod to move in a vertical direction, and the horizontal driving member is used to drive the lifting and pushing rod to move in a direction close to or away from the pushing arm.

[0015] By adopting the above technical solution, when conveying pipes, the telescopic driving member is started, and the telescopic driving member drives the lifting and pushing rod, so that the lifting and pushing rod moves in an inclined direction from bottom to top toward the pushing arm under the action of the telescopic driving member, so that each pipe moves forward one pipe storage position in the direction of the pushing arm. In the process of driving the lifting and pushing rod, the telescopic driving member only needs to drive the lifting and pushing rod in a single direction, thereby further simplifying the control logic, increasing the stability of the pipe feeding device during operation, and reducing the control cost.

[0016] When conveying the pipe, the vertical drive component first drives the lifting and pushing rod to make the lifting and pushing rod rise and lift the pipe, and at the same time make the bottom of the pipe higher than the top of the positioning plate, and then the horizontal drive component drives the lifting and pushing rod to move in the direction close to the pushing arm. When the pipe moves forward a distance of a pipe storage position, the vertical drive component drives the lifting and pushing rod in the opposite direction to make the lifting and pushing rod descend, and the pipe falls into the pipe storage position, and then the horizontal drive component drives the lifting and pushing rod in the opposite direction to reset the lifting and pushing rod, so as to facilitate the next pushing of the pipe in the direction close to the pushing arm.

[0017] Optionally, a guide beam and a connecting beam are provided at the bottom of the lifting and pushing rod, the guide beam is slidably connected to the connecting beam along the vertical direction, and the connecting beam is slidably connected to the frame along a direction approaching or moving away from the pushing arm.

[0018] By adopting the above technical solution, when the lifting and pushing rod transports the pipe toward the direction close to the pushing arm, the lifting and pushing rod first drives the guide beam to move in the vertical direction so that the guide beam and the connecting beam slide relative to each other, and then the lifting and pushing rod drives the connecting beam to move in the horizontal direction so that the connecting beam and the frame slide relative to each other, so as to increase the stability of the lifting and pushing rod during movement.

[0019] Optionally, a transmission tooth is provided at the bottom of the pushing arm, and the frame is rotatably connected to a matching tooth that meshes and transmits with the transmission tooth, and the matching teeth in multiple groups of the feeding mechanisms rotate synchronously through the transmission shaft.

[0020] By adopting the above technical scheme, when the telescopic power part drives the pushing arm, the pushing arm and the frame slide relative to each other, and then the pushing arm drives the transmission teeth to move, and the matching teeth drive the transmission shaft to rotate under the transmission action of the transmission teeth, so that multiple matching teeth rotate synchronously, so that the movement speeds and movement strokes of multiple pushing arms are consistent, and the situation where there are differences in the movement speeds and movement strokes of multiple pushing arms is overcome, so as to avoid the movement speed and movement stroke of a certain pushing arm being inconsistent with the movement speeds and movement strokes of other pushing arms, which may cause damage to the pipe, and at the same time, it can also increase the connection stability between the pipe and the pushing arm, and avoid the movement speed and movement stroke of a single pushing arm being inconsistent with the movement speed and movement stroke of other pushing arms, which may cause the pipe to separate from the pushing arm, thereby improving the success rate of pipe feeding, reducing the failure rate of the pipe feeding device, and increasing the service life of the pipe feeding device.

[0021] Optionally, the frame is provided with a detection switch for controlling the telescopic driving member, and the detection switch is arranged corresponding to the pipe storage position close to the pushing arm. When a pipe is placed on the pipe storage position close to the pushing arm, the pipe triggers the detection switch to stop the telescopic driving member from working.

[0022] By adopting the above technical solution, when placing pipes in the pipe storage positions, there may be a situation where a pipe is forgotten to be placed in a certain pipe storage position. During the operation of the pipe loading device, if the detection switch does not detect the pipe, the telescopic drive member will work to make the pipe located at the next pipe storage position advance the distance of one pipe storage position until the detection switch is triggered. In this process, the situation where the push arm moves without load is avoided, thereby improving the loading efficiency of the pipe loading device. In addition, no staff intervention is required during the entire process, thereby improving the automation level of the pipe loading device and enhancing the customer's usage experience.

[0023] Optionally, the pushing arm includes a pushing rod and a pushing plate arranged at one end of the pushing rod, the pushing plate has a guide surface and a blocking surface connected to the guide surface, the guide surface and the blocking surface form a pushing position for accommodating the pipe, the pushing plate is located at one end of the frame, and the telescopic power member acts on the pushing rod.

[0024] By adopting the above technical solution, when the lifting and pushing rod descends after conveying the pipe, the pipe located on the top of the pushing plate falls to the guide surface, so that the pipe hits the blocking surface under the action of the guide tube, that is, the pipe is located in the pushing position, and then the telescopic power part drives the pushing rod, so that the pushing rod drives the pushing plate to convey the pipe to the top of the lifting mechanism of the cutting machine body to complete the loading.

[0025] The setting of the pushing rod can increase the movement stroke of the pushing plate, so that the pushing plate can push more types of pipes. At the same time, the setting of the pushing plate can also reduce the weight of the pushing arm, so as to reduce the vertical deformation of the pushing arm, increase the stability of the pushing arm, and increase the accuracy of pipe transportation.

[0026] Optionally, both the guide surface and the blocking surface are provided with buffer pads.

[0027] By adopting the above technical solution, when the lifting push rod descends, the pipe located on the top of the push plate contacts the buffer pad on the guide surface to reduce the noise generated by the impact of the pipe and the push plate, and reduce the shaking of the push arm caused by the impact of the pipe and the push plate, thereby increasing the stability of the push arm and increasing the service life of the push arm. After the pipe slides along the guide surface, the pipe contacts the buffer pad provided on the blocking surface to further reduce the noise generated by the impact of the pipe and the push plate, and reduce the shaking of the push arm caused by the impact of the pipe and the push plate, thereby further increasing the stability of the push arm and further increasing the service life of the push arm.

[0028] Optionally, the rack is provided with an in-place switch for detecting the pushing arm, and the in-place switch is triggered when the pushing arm is in the retracted state.

[0029] By adopting the above technical solution, after the pipe feeding device is started, if the detection switch is triggered, it means that the pushing arm is in a retracted state at this time, and then the telescopic drive component can drive the lifting pushing rod normally to avoid the situation where the pushing arm is not in a retracted state, causing the pipe to fall. At the same time, no staff intervention is required in this process, which further improves the automation level of the pipe feeding device and improves the customer's usage experience.

[0030] Optionally, a positioning frame is further included, which is located on the same side of the multiple groups of feeding mechanisms, and the positioning frame has an alignment plate.

[0031] By adopting the above technical solution, when placing the pipe on the feeding mechanism, the staff can press one end of the pipe against the alignment plate to make one end of multiple pipes in a flush state, so that the pipe cutting machine body can clamp the pipe and improve the feeding efficiency.

[0032] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0033] 1. The pipe loading device in the present application includes at least two groups of loading mechanisms, the loading structure includes a frame, a pushing mechanism arranged on the frame and a pushing arm located at one end of the frame, a plurality of pipe storage positions are arranged in sequence on the top of the frame along the direction close to or away from the pushing arm, the pushing assembly includes a lifting and pushing rod and a telescopic driving member acting on the lifting and pushing rod, a plurality of pipe pushing positions are arranged on the top of the lifting and pushing rod corresponding to the pipe storage position, when the telescopic driving member is extended, the pipe pushing position lifts the pipe and transports it in the direction of the pushing arm, so that the pipe advances in the direction close to the pushing arm by a distance of the pipe storage position, and the frame is provided with a telescopic power member acting on the pushing arm, so that the pushing arm has a feeding state moving in the direction away from the frame and a retracted state moving in the direction close to the frame. Since the telescopic driving member and the telescopic power member are used in the present application, the use of servo motors and reduction motors is avoided, the cost of the pipe loading device is reduced, and the control logic of the pipe loading device is simplified, thereby increasing the stability of the pipe loading device. In addition, the present application is provided with multiple pipe storage positions and multiple pipe pushing positions to realize separate storage and separate transportation of multiple pipes, avoiding adjacent pipes from conflicting with each other, resulting in greater difficulty in material separation, and thereby improving the loading success rate of the pipe loading device.

[0034] 2. The top of the rack in the application is detachably connected with a positioning plate, and the positioning plate is provided with a plurality of positioning notches in sequence along the direction close to or away from the pushing arm. The positioning notches form a pipe storage position, so that the staff can choose to replace the appropriate positioning plate according to the cross-sectional size of the pipe.

[0035] 3. In the present application, a transmission tooth is provided at the bottom of the pushing arm, and the frame is rotatably connected to a matching tooth which is meshed with the transmission tooth. The matching teeth in multiple groups of feeding mechanisms rotate synchronously through the transmission shaft. When the telescopic power part drives the pushing arm, the pushing arm and the frame slide relative to each other, and then the pushing arm drives the transmission tooth to move. The matching teeth drive the transmission shaft to rotate under the transmission action of the transmission tooth, so that the multiple matching teeth rotate synchronously, thereby making the movement speed and movement stroke of the multiple pushing arms consistent. At the same time, the connection stability between the pipe and the pushing arm can be increased, thereby improving the feeding engineering rate of the pipe, reducing the failure rate of the pipe feeding device, and improving the service life of the pipe feeding device.

[0049] Reference Figures 1 to 5 , a pipe feeding device, which includes at least two groups of feeding mechanisms 1, each group of feeding mechanisms 1 includes a frame 11, a pushing assembly 12 arranged on the frame 11 and a pushing arm 13 located at one end of the frame 11, and a plurality of pipe storage positions 114 are sequentially arranged on the top of the frame 11 along the direction close to or away from the pushing arm 13, the pushing assembly 12 includes a lifting and pushing rod 121 and a telescopic driving member 122 acting on the lifting and pushing rod 121, and a plurality of pipe pushing positions 125 are arranged on the top of the lifting and pushing rod 121 corresponding to the pipe storage position 114. When the telescopic driving member 122 is extended, the pipe pushing position 125 lifts and transports the pipe so that the pipe moves toward the direction close to the pushing arm 13 by the distance of the pipe storage position 114, and the frame 11 is provided with a telescopic power member 111 acting on the pushing arm 13, so that the pushing arm 13 has a feeding state moving toward the direction away from the frame 11 and a retracted state moving toward the direction close to the frame 11.

[0050] When loading pipes, first place multiple pipes in multiple pipe storage positions 114 respectively, and then start the telescopic driving member 122 to drive the lifting and pushing rod 121, and the pipe pushing position 125 on the lifting and pushing rod 121 contacts the pipe and lifts the pipe, and at the same time, all pipes are advanced in the direction of the pushing arm 13 by the distance of a pipe storage position 114, that is, the pipe close to the pushing arm 13 moves to the pushing arm 13, and other pipes move forward to the next pipe storage position 114, and then start the telescopic power member 111, and the telescopic power member 111 drives the pushing arm 13 to move toward the feeding state, that is, the pushing arm 13 drives the pipe on its upper part to move in the direction away from the frame 11 and move to above the lifting mechanism of the cutting machine body, and the lifting mechanism rises and lifts the pipe to complete the loading action.

[0051] Since the present application adopts the telescopic driving member 122 and the telescopic power member 111, the use of the servo motor and the reduction motor is avoided, the cost of the pipe feeding device is reduced, and the control logic of the pipe feeding device is simplified, and the stability of the pipe feeding device is increased. In addition, the present application is provided with a plurality of pipe storage positions 114 and a plurality of pipe pushing positions 125 to realize the separate storage and separate transportation of a plurality of pipes, avoiding the adjacent pipes from conflicting with each other, resulting in a greater difficulty in dividing the materials, and thus improving the feeding success rate of the pipe feeding device.

[0052] The present application does not specifically limit the number of the feeding mechanism 1. Preferably, refer to Figure 1 The feeding mechanism 1 is provided with three groups, and the three groups of feeding mechanisms 1 are arranged in sequence and spaced along the length direction of the cutting machine body to increase the stability of conveying the pipe. In other embodiments, the feeding mechanism 1 can also be provided with two groups, four groups or more groups.

[0053] In a preferred embodiment, referring to Figure 1 The pipe feeding device also includes a positioning frame 2, which is located on the same side of the multiple feeding mechanisms 1. The positioning frame 2 has an alignment plate 21. The top of the alignment plate 21 is higher than the pipe storage position 114 and the bottom is lower than the pipe storage position 114, so that when the pipe is placed on the feeding mechanism 1, the staff can put one end of the pipe against the alignment plate 21 to make one end of the multiple pipes in a flush state, so that the pipe cutting machine body can clamp the pipe.

[0054] The present application does not specifically limit the formation method of the pipe storage position 114. Preferably, refer to Figure 4 and Figure 5A positioning plate 113 is detachably connected to the top of the frame 11 , and a plurality of positioning notches are sequentially arranged on the positioning plate 113 along a direction approaching or away from the pushing arm 13 , and the positioning notches form a pipe storage position 114 .

[0055] When using the pipe feeding device in the present application, the appropriate positioning plate 113 can be selected and replaced according to the cross-sectional size of the pipe. At the same time, the positioning notch on the positioning plate 113 forms a pipe storage position 114, which can increase the structural strength of the pipe storage position 114 while reducing the production cost of the pipe feeding device, so as to reduce the distance between adjacent pipe storage positions 114, and to arrange as many pipe storage positions 114 as possible on the rack 11 of the same length.

[0056] Further, see Figure 2 , Figure 3 and Figure 4 The positioning notch is V-shaped to increase the stability of the pipe placed in the pipe storage position 114, so as to facilitate the pipe pushing position 125 to lift and transport the pipe.

[0057] In a preferred embodiment, referring to Figure 4 A positioning groove 112 is provided on the top of the frame 11, and the bottom of the positioning plate 113 extends into the positioning groove 112, and a positioning bolt 115 is passed through the top of the frame 11 and penetrates the positioning plate 113 to realize a detachable connection between the positioning plate 113 and the frame 11, so as to facilitate the staff to replace the positioning plate 113 while increasing the connection stability between the positioning plate 113 and the frame 11.

[0058] In other embodiments, the pipe storage position 114 can also be formed by a plurality of positioning blocks provided on the top of the frame 11, a V-shaped groove is provided on the top of the positioning block, and the groove wall of the V-shaped groove is formed.

[0059] The present application does not specifically limit the structure of the pipe pushing position 125. Figure 4 Preferably, the top of the lifting and pushing rod 121 is detachably connected to a limiting plate 124, and the limiting plate 124 is sequentially provided with a plurality of limiting notches along a direction approaching or away from the pushing arm 13, and the limiting notches form a pipe pushing position 125.

[0060] When using the pipe feeding device in the present application, you can choose to replace the pipe pushing positions 125 with the same number of limiting plates 124 as the pipe storage positions 114 according to the number of pipe storage positions 114.

[0061] Further, see Figure 4 The limiting notch is V-shaped to increase the stability of the pipe located in the limiting notch, thereby increasing the stability of the lifting and pushing rod 121 in conveying the pipe.

[0062] In other embodiments, the pipe pushing position 125 can also be formed by providing a plurality of limit blocks on the top of the lifting and pushing rod 121, and the top of the limit block is provided with a V-shaped notch, and the wall of the V-shaped notch is formed.

[0063] The present application does not specifically limit the structure of the telescopic driving member 122, which may adopt any one of the following embodiments:

[0064] Embodiment 1: In this embodiment, the extension direction of the telescopic driving member 122 is arranged from bottom to top and tilted toward the pushing arm 13.

[0065] That is to say, a group of telescopic driving members 122 are provided, and the telescopic direction of the telescopic driving member 122 is arranged to be inclined from bottom to top toward the pushing arm 13, so that when the pipes are transported, the telescopic driving member 122 is started, and the lifting pushing rod 121 pushes each pipe to move forward one pipe storage position 114 in the direction of the pushing arm 13.

[0066] In this embodiment, the telescopic driving member 122 can be a pneumatic cylinder, a hydraulic cylinder or an electric push rod to reduce the production cost of the pipe feeding device, simplify the control logic of the pipe feeding device, and thus increase the stability of the pipe feeding device.

[0067] Preferably, the telescopic driving rod is a cylinder to further reduce the production cost of the pipe feeding device.

[0068] Furthermore, a guide rod is provided at the bottom of the lifting and pushing rod 121, and a guide seat is provided on the frame 11. The guide rod is passed through the guide seat, and the lifting and pushing rod 121 is guided by the sliding cooperation between the guide rod and the guide seat.

[0069] Implementation method 2. In this implementation method, refer to Figure 4 The telescopic driving member 122 includes a vertical driving member 142 and a horizontal driving member 143. The vertical driving member 142 is used to drive the lifting and pushing rod 121 to move in the vertical direction, and the horizontal driving member 143 is used to drive the lifting and pushing rod 121 to move in the direction close to or away from the pushing arm 13.

[0070] That is to say, the telescopic driving member 122 is provided with two groups, and the two groups of telescopic driving members 122 are divided into vertical driving members 142 and horizontal driving members 143. Then, when the pipe is transported, the vertical driving member 142 drives the lifting and pushing rod 121 to rise and lift the pipe, and at the same time makes the bottom of the pipe higher than the top of the positioning plate 113, and then the horizontal driving member 143 drives the lifting and pushing rod 121 to make the lifting and pushing rod 121 move in the direction close to the pushing arm 13. When the pipe moves forward a distance of a pipe storage position 114, the vertical driving member 142 drives the lifting and pushing rod 121 in the reverse direction to make the lifting and pushing rod 121 descend, and the pipe falls into the pipe storage position 114, and then the horizontal driving member 143 drives the lifting and pushing rod 121 in the reverse direction to reset the lifting and pushing rod 121, so as to facilitate the next pushing of the pipe in the direction close to the pushing arm 13.

[0071] In this embodiment, the vertical driving member 142 and the horizontal driving member 143 can both be cylinders, hydraulic cylinders or electric push rods to reduce the production cost of the pipe feeding device, simplify the control logic of the pipe feeding device, and thereby increase the stability of the pipe feeding device.

[0072] Preferably, the horizontal driving member 143 and the vertical driving member 142 are both cylinders to further reduce the production cost of the pipe feeding device.

[0073] In a preferred embodiment, referring to Figure 4 A guide beam 127 and a connecting beam 129 are provided at the bottom of the lifting and pushing rod 121. The guide beam 127 is slidably connected to the connecting beam 129 along the vertical direction, and the connecting beam 129 is slidably connected to the frame 11 along the direction approaching or moving away from the pushing arm 13.

[0074] Specifically, the vertical driving member 142 is connected to the connecting beam 129 and acts on the lifting and pushing rod 121, so that when the vertical driving member 142 drives the lifting and pushing rod 121, the lifting and pushing rod 121 drives the guide beam 127 to move, and the guide beam 127 and the connecting beam 129 slide relative to each other, so that the sliding cooperation between the guide beam 127 and the connecting beam 129 guides and limits the lifting and pushing rod 121 to increase the stability of the lifting and pushing rod 121; the horizontal driving member 143 is connected to the frame 11 and acts on the connecting beam 129, so that when the horizontal driving member 143 drives the connecting beam 129, the connecting beam 129 drives the guide beam 127 and the vertical driving member 142 to move, and the guide beam 127 and the vertical driving member 142 drive the lifting and pushing rod 121 to move to increase the stability of the lifting and pushing rod 121.

[0075] Further, see Figure 4 and Figure 5The frame 11 is provided with a first guide rail, and the connecting beam 129 is provided with a first slider. The first slider is slidably matched with the first guide rail to increase the connection stability between the connecting beam 129 and the frame 11. At the same time, the sliding match between the first slider and the first slide rail guides the movement of the connecting beam 129 to increase the stability of the connecting beam 129 during movement.

[0076] Further, see Figure 4 and Figure 5 The guide beam 127 is provided with a second guide rail, and the connecting beam 129 is provided with a second slider. The second slider is slidably matched with the second guide rail to increase the connection stability between the guide beam 127 and the connecting beam 129. At the same time, the sliding match between the second slider and the second guide rail guides the movement of the guide beam 127 to increase the stability of the guide beam 127 during movement.

[0077] In a preferred embodiment, referring to Figure 5 A transmission tooth 134 is provided at the bottom of the pushing arm 13, and the frame 11 is rotatably connected to a matching tooth 118 that meshes and drives with the transmission tooth 134. The matching teeth 118 in the multiple groups of feeding mechanisms 1 rotate synchronously through the transmission shaft 119.

[0078] When the telescopic power part 111 drives the pushing arm 13, the pushing arm 13 and the frame 11 slide relative to each other, and then the pushing arm 13 drives the transmission tooth 134 to move, and the matching tooth 118 drives the transmission shaft 119 to rotate under the transmission action of the transmission tooth 134. Since multiple matching teeth 118 rotate synchronously through the transmission shaft 119, multiple matching teeth 118 rotate synchronously, so that the movement speed and movement stroke of multiple pushing arms 13 are consistent, overcoming the situation that there are differences in the movement speeds and movement strokes of multiple pushing arms 13, so as to avoid the movement speed and movement stroke of a certain pushing arm 13 being inconsistent with the movement speed and movement stroke of other pushing arms 13, which may cause damage to the pipe. At the same time, it can also increase the connection stability between the pipe and the pushing arm 13, avoid the movement speed and movement stroke of a single pushing arm 13 being inconsistent with the movement speed and movement stroke of other pushing arms 13, which may cause the pipe to separate from the pushing arm 13, thereby improving the success rate of pipe feeding, reducing the failure rate of the pipe feeding device, and improving the service life of the pipe feeding device.

[0079] The present application does not specifically limit the structure of the transmission teeth 134 and the matching teeth 118. Preferably, refer to Figure 5The bottom of the push arm 13 is provided with an extension plate 133, and the bottom of the extension plate 133 is provided with a rack, and the teeth on the rack constitute a transmission tooth 134, so as to reduce the production cost of the pipe feeding device. The frame 11 is rotatably connected with a gear, and the teeth on the gear constitute a matching tooth 118. The transmission shaft 119 is coaxially fixedly connected with the gear to further ensure that the movement speed and movement stroke of the multiple push arms 13 are consistent, thereby improving the feeding success rate of the pipe feeding device.

[0080] In a preferred embodiment, referring to Figure 2 The frame 11 is provided with a detection switch 150 for controlling the telescopic driving member 122. The detection switch 150 is set corresponding to the pipe storage position 114 close to the pushing arm 13. When a pipe is placed on the pipe storage position 114 close to the pushing arm 13, the pipe triggers the detection switch 150, and the detection switch 150 controls the telescopic driving member 122 to stop working.

[0081] Specifically, the pipe feeding device also includes a host, which controls the start or stop of the telescopic drive 122. The detection switch 150 is connected to the host signal so that when the detection switch 150 is triggered, the detection switch 150 sends a signal to the host to enable the host to control the telescopic drive 122 to stop working.

[0082] During the operation of the pipe feeding device, if the detection switch 150 does not detect the pipe, the telescopic drive 122 will work to make the pipe located at the next pipe storage position 114 move forward the distance of one pipe storage position 114 until the detection switch 150 is triggered. In this process, the situation where the push arm 13 moves without load is avoided, thereby improving the feeding efficiency of the pipe feeding device. In addition, no staff intervention is required during the entire process, thereby improving the automation level of the pipe feeding device and enhancing the customer's usage experience.

[0083] The present application does not specifically limit the structure of the detection switch 150. Preferably, the detection switch 150 is a pressure switch, so that when a pipe is placed on the pipe storage position 114 close to the push arm 13, the pipe applies pressure to the pressure switch, so that the pressure switch sends a signal to the host, and the host stops the telescopic drive member 122 after receiving the signal. In other embodiments, the detection switch 150 can also be an infrared ray switch.

[0084] The present application does not specifically limit the structure of the push arm 13. Preferably, refer to Figure 4 The pushing arm 13 includes a pushing rod 131 and a pushing plate 132 arranged at one end of the pushing rod 131. The pushing plate 132 has a guiding surface 136 and a blocking surface 137 adjacent to the guiding surface 136. The guiding surface 136 and the blocking surface 137 form a pushing position for accommodating the pipe. The pushing plate 132 is located at one end of the frame 11, and the telescopic power member 111 acts on the pushing rod 131.

[0085] When the lifting push rod 121 descends after conveying the pipe, the pipe located on the top of the pushing plate 132 falls to the guide surface 136, so that the pipe hits the blocking surface 137 under the action of the guide tube, that is, the pipe is located in the pushing position, and then the telescopic power part 111 drives the pushing rod 131, so that the pushing rod 131 drives the pushing plate 132 to convey the pipe to the top of the lifting mechanism of the cutting machine body to complete the loading.

[0086] The setting of the pushing rod 131 can increase the movement stroke of the pushing plate 132, so that the pushing plate 132 can push more types of pipes. At the same time, the setting of the pushing plate 132 can also reduce the weight of the pushing arm 13, so as to reduce the vertical deformation of the pushing arm 13, increase the stability of the pushing arm 13, and increase the accuracy of pipe transportation.

[0087] The present application does not specifically limit the structure of the telescopic power member 111. Preferably, refer to Figure 3 The telescopic power member 111 is a cylinder, the push rod 131 is a hollow structure, the cylinder body of the cylinder is hinged to the frame 11, and the piston rod of the cylinder extends into the push rod 131 and is fixedly connected to the push rod 131. In other embodiments, the telescopic power member can also be a structure that can be telescopically moved, such as an electric push rod or a hydraulic cylinder.

[0088] In a preferred embodiment, referring to Figure 4 and Figure 5 The push rod 131 is provided with a third guide rail, and the frame 11 is provided with a third slider, which is slidably connected to the third guide rail to increase the stability of the push rod 131 during movement, and at the same time increase the maximum pressure that the push rod 131 can withstand, so as to increase the service life of the push arm 13 and reduce the failure rate of the push arm 13.

[0089] Further, see Figure 4 The guide surface 136 and the blocking surface 137 are both provided with a buffer pad 138, which can reduce the noise generated by the collision between the pipe and the pushing plate 132, and at the same time reduce the shaking of the pushing arm 13 caused by the collision between the pipe and the pushing plate 132, thereby increasing the stability of the pushing arm 13 and increasing the service life of the pushing arm 13.

[0090] Preferably, the buffer pad 138 is a structure made of rubber or silicone material.

[0091] In a preferred embodiment, referring to Figure 3 The frame 11 is provided with an in-position switch 152 for detecting the pushing arm 13 , and the in-position switch 152 is triggered when the pushing arm 13 is in a retracted state.

[0092] Specifically, the in-position switch 152 is connected to the host signal, and the host controls the start or stop of the telescopic power member 111.

[0093] The present application does not make any specific limitation on the structure of the in-position switch 152 , which may be a pressure switch or an infrared switch, as long as it can detect the in-position of the push arm 13 .

[0094] In a preferred embodiment, referring to Figure 4 The frame 11 is provided with a cylinder magnetic switch 153, which is connected to the host signal, and is used to detect whether the telescopic drive member 122 is extended, so as to unify the actions of the telescopic drive members 122 in multiple groups of feeding mechanisms 1, increase the stability when feeding the pipe, and enable the host to control the telescopic drive member 122 and the telescopic power member 111 to work.

[0095] In a preferred embodiment, referring to Figure 1 A connecting rod 116 is provided at one end of the frame 11 close to the pushing arm 13, and the connecting rod 116 is connected to the pipe cutting machine body to increase the stability of the frame 11, improve the feeding accuracy of the pipe feeding device on the pipe, and thus improve the success rate of feeding.

[0096] Specifically, after the pipe feeding device is started, if the detection switch 150 is triggered, it means that the pushing arm 13 is in a retracted state, and then the telescopic driving member 122 can normally drive the lifting pushing rod 121 to avoid the situation where the pushing arm 13 is not in a retracted state, causing the pipe to fall. At the same time, no staff intervention is required in this process, which further improves the automation level of the pipe feeding device and improves the customer's usage experience.

[0097] When the detection switch 150 is not triggered, the telescopic drive member 122 continues to work until the pipe moves to the pipe storage position 114 close to the pushing arm 13. If the number of times the telescopic drive member 122 continues to work is equal to the number of pipe storage positions 114, and the detection switch 150 is still not triggered, the detection switch 150 sends a signal to the host, the host reminds the staff, and the staff manually loads the material again.
