Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to a feeding device for a pipe cutting machine. Background Art

[0002] The feeding device of the pipe cutting machine includes a conveyor belt for conveying pipes. At present, most feeding devices of the pipe cutting machine use a button-type travel switch to control the start and stop of the chain, and the button-type travel switch is set at one end close to the pipe cutting machine; the button-type travel switch is similar to a push-button switch, and relies on the mechanical moving parts to collide with the push rod of the travel switch to automatically control the on and off of the contacts; the pipe moves to the button-type forming switch and contacts the button-type travel switch; most push-button travel switches have a reaction force system, which can automatically reset after being collided by mechanical moving parts.

[0003] Regarding the above-mentioned related technologies, a travel switch is used to control the start and stop of the feeding chain, and the signal is only fed back once. If the pipe is transported to the end of the feeding device close to the cutting machine, once a power outage occurs or the feeding device stops suddenly due to an emergency, after the feeding device is powered on, the feeding device will not be able to identify whether there is a pipe on the conveying chain at this time, which will cause problems when feeding the pipe. Utility Model Content

[0004] In order to solve the above problems, the present application provides a feeding device for a pipe cutting machine.

[0005] This application provides a feeding device for a pipe cutting machine, which adopts the following technical solution:

[0006] A feeding device for a pipe cutting machine includes several feeding assemblies, and is characterized in that the several feeding assemblies are arranged parallel to each other, and one end of the several feeding assemblies close to the pipe cutting machine is provided with a contact sensor for detecting the pipeline.

[0007] By adopting the above technical solution, the pipeline is first placed on the loading assembly using a crane or other equipment, and then the loading assembly is used to transport the pipeline. When the pipeline moves to the position of the contact sensor, it contacts the contact sensor. At this time, the contact sensor is under pressure. If a power outage occurs or the loading device stops suddenly due to an emergency, after the loading device is powered on, the contact sensor is still under pressure. The loading device can still recognize that there is a pipeline on the loading assembly at this time, reducing the problem of the conveyor belt cutting the pipeline, thereby ensuring the efficiency of conveying the pipeline.

[0008] Optionally, several of the loading assemblies include a support frame, and the upper ends of several of the support frames are provided with horizontal platforms. One end of several of the horizontal platforms in the length direction is rotatably connected to sprocket 1, and the other end of several of the horizontal platforms in the length direction is rotatably connected to sprocket 2. The sprocket 1 and the sprocket 2 located on the same horizontal platform are engaged with a chain for conveying the pipeline on the outside.

[0009] By adopting the above technical solution, the rotation of sprocket one is controlled to drive sprocket two to rotate, thereby driving the chain to move, and then driving the pipe located at the upper end of the chain to move. The structure is simple and the driving is convenient.

[0010] Optionally, limit blocks are set at equal intervals on the outside of several of the chains.

[0011] By adopting the above technical solution, when loading the pipeline, the pipeline is placed between two limit blocks by using a crane, and then the pipeline is transported by manipulating the movement of the chain, thereby improving the stability of the conveying pipeline.

[0012] Optionally, it also includes a rotating rod, which is located below the several support frames. The outer sleeve of the rotating rod is provided with several synchronous wheels 1, each synchronous wheel 1 corresponds to a support frame one by one, and each horizontal platform is rotatably connected to a synchronous wheel 2 on one side in the length direction. The outer sleeve of the synchronous wheel 1 and the synchronous wheel 2 located on the same support frame is provided with a synchronous belt 1.

[0013] By adopting the above technical solution, by manipulating the rotation of the rotating rod, several synchronous wheels 1 can be driven to rotate, and then the synchronous belt 1 can be driven to rotate, and then the synchronous wheel 2 can be driven to rotate, so as to drive several sprockets 1 to rotate. If there is a problem with the feeding assembly, the staff can easily go to one side of the feeding assembly to repair it, which takes up less space and is more convenient to repair.

[0014] Optionally, one of the support frames is configured as a drive frame, a drive motor is slidably connected to the drive frame, a synchronous wheel three is provided on the outer sleeve of the output shaft of the drive motor, a synchronous wheel four is provided on the outer sleeve of the rotating rod, the synchronous wheel four is located below the drive frame, and the outer sleeves of the synchronous wheel three and the synchronous wheel four are provided with a synchronous belt two.

[0015] By adopting the above technical solution, the synchronous wheel three can be driven to rotate by operating the output shaft of the driving motor to rotate, and the synchronous wheel four can be driven to rotate under the action of the synchronous belt two, thereby driving the rotating rod to rotate. The structure is simple and the driving is convenient. The driving motor is located on the driving frame and occupies a small space. If there is a problem with the loading assembly, the staff can easily go to one side of the loading assembly to repair it, which is very convenient.

[0016] Optionally, one side of each support frame in the length direction is vertically slidably connected to a lifting frame for lifting the pipe. Several lifting frames are arranged at one end of the support frame close to the pipe cutting machine, and a clamping device for clamping the pipe is also provided on the lifting frame.

[0017] By adopting the above technical solution, as the pipeline is transported to the lifting frame, the lifting frame is raised by operating it, and then the pipeline can be clamped by a clamping device, and then the pipeline can be moved to the next work station by a crane or other driving parts, and the pipeline is relatively stable when lifted.

[0018] Optionally, an infrared sensor is provided at one end of several limit blocks in the width direction, two sliding plates are slidably connected in each limit block, a double-headed cylinder is horizontally arranged in the limit block, the two sliding plates are fixedly connected to the two piston rods of the double-headed cylinder respectively, and the two sliding plates in the same limit block are both arranged in an arc shape on the sides away from each other, and a clearance opening is opened on both sides of each limit block in the width direction. When the piston rod of the double-headed cylinder is extended, the sliding plate extends to the outside of the clearance opening, and a controller is provided inside each limit block. The infrared sensors on the same limit block are electrically connected to the controller in the limit block, and the controllers in the same limit block are electrically connected to the double-headed cylinder in the same limit block.

[0019] By adopting the above technical solution, the pipe is placed between the two limit blocks using a clamping device. At this time, the infrared sensor detects the presence of the clamping device and sends an electrical signal to the controller. The controller transmits the control signal to the double-headed cylinder. The two piston rods of the double-headed cylinder extend at the same time, driving the two sliding plates to move away from each other, thereby improving the stability of the pipeline during transportation.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. First, place the pipe on the loading assembly using a crane or other equipment, and then use the loading assembly to transport the pipe. When the pipe moves to the contact sensor, it contacts the contact sensor, which is then pressurized. If a power outage occurs or the loading device stops suddenly due to an emergency, the contact sensor will still be pressurized after the loading device is powered on. The loading device can still identify the presence of the pipe on the loading assembly, reducing the risk of the conveyor belt cutting the pipe and ensuring the efficiency of the pipe transportation.

[0022] 2. Use the clamping device to place the pipe between the two limit blocks. At this time, the infrared sensor detects the presence of the clamping device and sends an electrical signal to the controller. The controller transmits the control signal to the double-headed cylinder. The two piston rods of the double-headed cylinder extend simultaneously, driving the two sliding plates to move away from each other, which can improve the stability of the pipeline during transportation.

[0031] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0032] An embodiment of the present application discloses a feeding device for a pipe cutting machine.

[0033] Example 1:

[0034] Reference Figure 1 and Figure 2 A feeding device for a pipe cutting machine includes a plurality of feeding assemblies 1, which are arranged parallel to each other. A contact sensor 21 is provided at one end of each feeding assemblies 1 close to the pipe cutting machine for detecting the pipe. First, the pipe is placed on the feeding assembly 1 using a crane or other equipment, and then the feeding assembly 1 is used to convey the pipe. When the pipe moves to the position of the contact sensor 21, the contact sensor 21 is subjected to the pressure of the pipe. At this time, the contact sensor 21 is under pressure. If a power outage occurs or the feeding device stops suddenly due to an emergency, after the feeding device is powered on, the contact sensor 21 is still under pressure. The feeding device can still recognize the presence of the pipe on the feeding assembly 1 at this time, thereby reducing the problem of the conveyor belt cutting the pipe, thereby ensuring the efficiency of conveying the pipe.

[0035] In this embodiment, the contact sensor 21 is preferably a pressure sensor that can detect the pipeline.

[0036] Reference Figure 1 and Figure 2 The feeding components 1 all include support frames 3, and the upper ends of several support frames 3 are provided with horizontal platforms 31. One end of the length direction of several horizontal platforms 31 is rotatably connected to sprocket 1 32, and the other end of the length direction of several horizontal platforms 31 is rotatably connected to sprocket 2 33. The sprocket 1 32 and the sprocket 2 33 located on the same horizontal platform 31 are engaged with the outside of the chain 34 for conveying the pipeline; limit blocks 4 are evenly spaced outside the several chains 34; first, use a crane to place the pipeline horizontally on the upper ends of several chains 34, and place the pipeline between two limit blocks 4, and then the chain 34 can be manipulated to move and thereby drive the pipeline to move, and the pipeline is limited by the limit blocks 4, thereby improving the stability of the conveying pipeline.

[0037] Reference Figure 2 and Figure 3 The loading device also includes a rotating rod 35, which is located below the several supporting frames 3, and the outer sleeve of the rotating rod 35 is provided with several synchronous wheels 351. Each synchronous wheel 351 corresponds to the supporting frame 3 one by one. One side of each horizontal platform 31 in the length direction is rotatably connected to the synchronous wheel 2 36, and the outer sleeve of the synchronous wheel 1 351 and the synchronous wheel 2 36 located on the same supporting frame 3 is provided with a synchronous belt 1 37. One of the supporting frames 3 is set as a driving frame 5, and the driving frame 5 is slidably connected to the driving motor 51. The outer sleeve of the output shaft of the driving motor 51 is provided with a synchronous wheel 3 511, and the outer sleeve of the rotating rod 35 is provided with a synchronous wheel 4 352. The synchronous wheel 4 352 is located below the driving frame 5, and the outer sleeve of the synchronous wheel 3 511 and the synchronous wheel 4 352 is provided with a synchronous belt 2 52; by operating the output shaft of the driving motor 51 to rotate, the synchronous wheel 3 511 can be driven to rotate, and under the action of the synchronous belt 2 52, the synchronous wheel 4 352 is driven to rotate, and then the rotating rod 35 is driven to rotate. The structure is simple and the driving is convenient.

[0038] Reference Figure 2 and Figure 3 As the rotating rod 35 rotates, it can drive several synchronous wheels 351 to rotate, and then drive the synchronous belt 1 37 to rotate, and then drive the synchronous wheel 2 36 to rotate, so as to drive several sprockets 1 32 to rotate. Under the action of the chain 34, the sprocket 2 33 is driven to rotate. At this time, the chain 34 moves, and then drives the pipeline to move. The structure is simple and the drive is convenient.

[0039] Reference Figure 2 and Figure 3 The driving motor 51 is slidably connected to the lower end of the driving frame 5. If there is a problem with the feeding assembly 1, the staff can easily go to one side of the feeding assembly 1 to repair it. The space occupied is small and the maintenance is more convenient.

[0040] Reference Figure 1 and Figure 4 One side of each support frame 3 in the length direction is vertically slidably connected to a lifting frame 6 for lifting the pipe. Several lifting frames 6 are arranged at one end of the support frame 3 close to the pipe cutting machine. The lifting frame 6 is also provided with a clamping device 61 for clamping the pipe. As the pipe is transported to the lifting frame 6, the lifting frame 6 is raised by manipulating the lifting frame 6, and then the clamping device 61 can be used to clamp the pipe. Then, a crane or other driving parts can be used to move the pipe to the next work station, and the pipe is relatively stable when lifted.

[0041] Among them, the lifting frame 6 is a prior art that can lift the pipeline, and will not be described in detail in this embodiment.

[0042] Among them, the clamping device 61 is a prior art that can clamp the pipeline, and will not be described in detail in this embodiment.

[0043] As the chain 34 transports the pipe, the pipe is moved to one end close to the cutting machine. A swing plate 2 is provided on the side of the horizontal platform 31 away from the lifting frame 6. The swing plate 2 is elastically arranged, and the contact sensors 21 are all arranged at the upper end of the swing plate 2. As the pipe moves to the swing plate 2, the swing plate 2 moves downward due to the pressure of the pipe. At this time, the contact sensor 21 is under pressure. If a power outage occurs or the feeding device stops suddenly due to an emergency, after the feeding device is powered on, the contact sensor 21 is still in a pressurized state. The feeding device can still identify that there is a pipe to be cut on the feeding component 1 at this time, reducing the problem of the conveyor belt cutting the pipe, thereby ensuring the efficiency of conveying the pipe to be cut.

[0044] As the lifting frame 6 lifts the pipeline, the swing plate 2 recovers, the pressure on the contact sensor 21 disappears, and the transportation of the pipeline is completed.

[0045] The implementation principle of a pipe cutting machine feeding device in the embodiment of the present application is as follows: the pipe is placed between two limit blocks 4, and then the output shaft of the driving motor 51 is operated to rotate to drive the synchronous wheel three 511 to rotate, and the synchronous wheel four 352 is driven to rotate under the action of the synchronous belt two 52, and then the rotating rod 35 is driven to rotate. The rotation of the rotating rod 35 can drive the plurality of synchronous wheels one 351 to rotate, and then the synchronous belt one 37 is driven to rotate, and then the synchronous wheel two 36 is driven to rotate, so as to drive the plurality of sprockets one 32 to rotate, and the sprocket two 33 is driven to rotate under the action of the chain 34. At this time, the chain 34 moves, and then the pipe is driven to move. The structure is simple and the driving is convenient. 4 is used to limit the pipeline, thereby improving the stability of the conveying pipeline. The driving motor 51 is slidably connected to the lower end of the driving frame 5. If there is a problem with the feeding component 1, the staff can easily go to the side of the feeding component 1 to repair it. The space occupied is small and the maintenance is relatively convenient. As the pipeline moves to the swing plate 2, the swing plate 2 moves downward due to the pressure of the pipeline. At this time, the contact sensor 21 is pressurized. If a power outage occurs or the feeding device stops suddenly due to an emergency, after the feeding device is powered on, the contact sensor 21 is still in a pressurized state. The feeding device can still identify that there is a pipeline to be cut on the feeding component 1 at this time, reducing the situation where problems with the conveyor belt cutting the pipeline occur, thereby ensuring the efficiency of conveying the pipeline to be cut.

[0046] Example 2:

[0047] Reference Figure 5 and Figure 6 The difference between the second embodiment and the first embodiment lies in the different arrangement of the limit block 4.

[0048] Reference Figure 5 and Figure 7 , one end of the width direction of the plurality of limit blocks 4 is provided with an infrared sensor 41 (refer to Figure 6 ), each limit block 4 is slidably connected to two sliding plates 42, a double-headed cylinder 43 is horizontally arranged in the limit block 4, the two sliding plates 42 are fixedly connected to the two piston rods of the double-headed cylinder 43, and the two sliding plates 42 in the same limit block 4 are both arranged in an arc shape on the side away from each other. A clearance opening 44 is opened on both sides of the width direction of each limit block 4. When the piston rod of the double-headed cylinder 43 is extended, the sliding plate 42 extends to the outside of the clearance opening 44. A controller is provided inside each limit block 4, and an infrared sensor 41 (refer to Figure 6 ) are electrically connected to the controller in the limit block 4, and the controllers located in the same limit block 4 are electrically connected to the double-headed cylinder 43 located in the same limit block 4.

[0049] Reference Figure 5 and Figure 7When loading, the pipe is placed between two limit blocks 4 using a clamping device. At this time, the infrared sensor 41 (refer to Figure 6 ) detects the presence of a clamping device and sends an electrical signal to the controller. The controller transmits the control signal to the double-headed cylinder 43. The two piston rods of the double-headed cylinder 43 extend at the same time, driving the two sliding plates 42 to move away from each other. The sliding plates 42 extended from the two adjacent limit blocks 4 clamp the pipeline, which can improve the stability of the pipeline during transportation.

[0050] Reference Figure 5 and Figure 7 As the chain 34 is conveyed, the pipe moves to the lifting frame 6. As the lifting frame 6 rises, the infrared sensors 41 (refer to Figure 6 ) detects the lifting frame 6, and at this time transmits the electrical signal to the controller, and the controller transmits the control signal to the double-headed cylinder 43. The two piston rods of the double-headed cylinder 43 retract at the same time, driving the two sliding plates 42 to move towards each other, thereby releasing the clamping of the pipeline. The structure is simple and easy to drive.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
