Description

Technical Field

[0001] The present application belongs to the technical field of feeding of tube cutting machines, and specifically relates to a feeding mechanism for a laser tube cutting machine. Background Art

[0002] The laser tube cutting machine is a device that focuses the laser emitted from a laser into a high-power density laser beam through an optical path system, and uses the laser beam to replace the traditional mechanical knife cutting equipment. It has the advantages of fast cutting speed, smooth incision and low processing cost, and can meet the cutting needs of tubes of various shapes.

[0003] The existing fully automatic feeding mechanism matched with the laser tube cutting machine generally includes a material belt type storage bin assembly with a feeding function, a frame assembly arranged between the material belt type storage bin assembly and the laser tube cutting machine, and a fork assembly arranged on the top of the frame assembly, wherein the fork assembly is provided with multiple groups and reciprocates between the material belt type storage bin assembly and the laser tube cutting machine, so that after the material belt type storage bin assembly drives the tube onto the frame assembly, the multiple groups of fork assemblies drive the tube located on the frame assembly to allow the tube to enter the laser tube cutting machine.

[0004] Since the material belt type storage bin assembly utilizes the winding of the material belt to make the material belt drive the pipe to rise, so that the pipe on the material belt close to the frame assembly moves to the top of the frame assembly to realize the loading of the pipe. As a result, the number of pipes delivered by the material belt type storage bin assembly to the frame assembly at a time cannot be controlled. During use, the staff is required to remove the excess pipes in real time, which increases the labor input cost of the laser pipe cutting machine, and thus leads to an increase in the pipe cutting cost. Utility Model Content

[0005] The present application provides a feeding mechanism for a laser tube cutting machine to achieve automatic removal of excess tubes, thereby reducing the tube cutting cost.

[0006] The technical solution adopted in this application is:

[0007] A feeding mechanism for a laser tube cutting machine comprises a frame, a material blocking assembly arranged on the frame and a rejection assembly arranged on the frame, the frame having a material guiding surface, the material guiding surface having a feeding end and a feeding end, the material blocking assembly and the rejection assembly are both arranged at the feeding end, the material blocking assembly can move relative to the material guiding surface so that the material blocking assembly has a material blocking state for blocking the tube located at the feeding end and a avoidance state for forming an avoidance state with the tube located at the feeding end, the rejection assembly can move in a direction away from the feeding end and act on the tubes stacked on the feeding end so that only a single tube located at the feeding end remains.

[0008] By adopting the above-mentioned technical scheme, when the feeding mechanism in the present application is used to feed the pipe, the material belt of the material belt type storage bin assembly is wound up so that the pipe moves to the feeding end under the action of the material belt. At this time, the material blocking assembly blocks the pipe so that only one pipe can stay at the feeding end. If at least two pipes are stacked on the feeding end, the rejection assembly is started to move the rejection assembly and reject the pipe on the upper layer, so that the pipe on the upper layer re-enters the material belt type storage bin assembly, and then the material blocking assembly moves to the avoidance state, so that the material blocking assembly and the pipe form an avoidance state, and the pipe can move to the unloading end, and then the lifting unit of the laser pipe cutting machine lifts the pipe to complete the loading of the pipe.

[0009] The feeding mechanism in the present application realizes that the feeding mechanism can only deliver one tube to the laser tube cutting machine at a time through the setting of the material blocking component and the rejection component, thereby avoiding the need to manually reject excess tubes, thereby avoiding the need for human intervention in the feeding process, thereby reducing the manual input when the feeding mechanism is working, and thus greatly reducing the tube cutting cost.

[0010] Optionally, the material baffle assembly includes a baffle and a baffle driving member disposed on a frame and used to drive the baffle to move; when the baffle is in the material baffle state, at least a portion of the baffle protrudes from the material guide surface; when the baffle is in the avoidance state, the baffle is located below the material guide surface.

[0011] By adopting the above technical solution, when only a single pipe is left at the feeding end, the baffle driving component is started, and then the baffle is moved to the bottom of the guide surface under the action of the baffle driving component, so that the baffle and the pipe at the feeding end form an avoidance, so that the pipe can move along the guide surface to the unloading end. In this process, the baffle only needs to move in a single direction, thereby simplifying the movement trajectory of the baffle, reducing the control program of the feeding mechanism, and further reducing the production cost of the feeding mechanism and the stability of the working state.

[0012] Optionally, the frame is provided with a movable plate and an adjusting unit, the adjusting unit acts on the movable plate to enable the movable plate to move in a direction close to or away from the feeding end, and the baffle and the baffle driving member are arranged on the movable plate.

[0013] By adopting the above technical solution, when loading different types of pipes, the adjusting unit is operated to adjust the movable plate, so that the distance between the end of the baffle away from the unloading end and the end of the loading end can just accommodate a single pipe, so that when the belt-type storage bin assembly transports the pipes, only a single pipe can stay at the loading end, thereby increasing the flexibility of the loading mechanism while ensuring that the loading mechanism can only transport a single pipe to the laser pipe cutting machine each time, thereby enabling the loading mechanism to load various types of pipes.

[0014] Optionally, the frame is provided with a scale, and a scale pointer pointing to the scale is provided on the side of the movable plate.

[0015] By adopting the above technical solution, when the operating adjustment unit is used to adjust the relative position of the baffle and the feeding end, the movable plate drives the scale pointer to move so that the scale pointer and the scale ruler move relative to each other. When the scale pointer points to the scale to be adjusted, the operation of the adjustment unit is stopped, thereby achieving the effect of facilitating the adjustment of the baffle to the accurate position, saving the staff time in adjusting the relative position of the baffle and the feeding end, and greatly improving the feeding efficiency of the feeding mechanism.

[0016] Optionally, an induction switch, an induction plate and an elastic member acting on the induction plate are provided at the end of the baffle away from the unloading end, and the pipe located at the loading end applies pressure to the induction plate toward the unloading end, so that the elastic member undergoes elastic deformation and the induction plate triggers the induction switch.

[0017] By adopting the above technical solution, after the pipe is conveyed to the loading end, the pipe located at the loading end contacts the induction plate and applies pressure toward the second end to the induction plate, so that the induction plate applies pressure to the elastic member, and the elastic member undergoes elastic deformation, thereby causing the induction plate to trigger the induction switch. At this time, the induction switch sends a signal to the material belt type storage bin assembly to cause the material belt type storage bin assembly to move in the opposite direction, thereby resetting the material belt type storage bin assembly to complete the loading of the material at the loading end, thereby increasing the automation level of the loading mechanism.

[0018] Optionally, the rejection assembly includes a rejection plate, a first driving member that drives the rejection plate to move in a direction close to or away from the feeding end, and a second driving member that is arranged on the frame and is used to drive the first driving member to move in a direction close to or away from the material guiding surface.

[0019] By adopting the above technical solution, when there are at least two stacked pipes at the feeding end, the second driving member is started, and the second driving member drives the first driving member to move the first driving member in a direction away from the material guide surface, and finally a distance of a single pipe is left between the bottom of the rejection plate and the material guide surface, and then the first driving member is started, and the first driving member drives the rejection plate to move in a direction away from the unloading end, so that the rejection plate drives the pipes located on the upper layer, so that the pipes located on the upper layer are separated from the feeding end and move to the storage unit to complete the removal of excess pipes. By setting the second driving member, the distance between the bottom of the rejection plate and the material guide surface can be adjusted, so that the rejection plate can remove pipes of various models, so as to ensure that the feeding mechanism can only deliver a single pipe to the laser pipe cutting machine at a time, thereby ensuring the feeding efficiency of the feeding mechanism, further avoiding the situation where the staff needs to remove the pipes, and ensuring the flexibility of the feeding mechanism.

[0020] Optionally, the first driving member is provided with a connecting seat, and the driving end of the second driving member is connected to the connecting seat.

[0021] By adopting the above technical solution, since the driving end of the second driving member is connected to the connecting seat, and the first driving member is arranged on the connecting seat, that is, the second driving member drives the connecting seat so that the connecting seat drives the first driving member to move, thereby avoiding the situation where the second driving member needs to be connected to the first driving member, which may cause damage to the first driving member, thereby reducing the assembly difficulty of the feeding mechanism and ensuring the service life of the feeding mechanism.

[0022] Optionally, the unloading end is arranged to extend obliquely downward from the loading end.

[0023] By adopting the above technical solution, since the unloading end is inclined and extended downward from the loading end, and then the blocking assembly and the pipe located at the loading end are avoided, the pipe located at the loading end can slide along the guide surface to the unloading end under the component force of its own gravity, thereby avoiding the need to set up other mechanisms to transport the pipes, reducing the driving structure required for the loading mechanism, and further reducing the production cost of the loading mechanism and the energy consumption of the loading mechanism.

[0024] Optionally, the feeding end is provided with a rolling wheel;

[0025] And / or, the material guiding surface is provided with a guide rail.

[0026] By adopting the above technical solution, when the pipe slides down along the guide surface, the rolling wheel and the pipe roll relative to each other to reduce the friction between the pipe and the feeding end, thereby ensuring that the pipe can slide along the guide surface to the unloading end under the component force of its own gravity, and at the same time can increase the speed at which the pipe slides down along the guide surface, thereby improving the feeding efficiency of the feeding mechanism.

[0027] When the pipe slides down along the guide surface, the pipe and the guide rail slide relative to each other to reduce the friction between the pipe and the guide surface, thereby ensuring that the pipe can slide along the guide surface to the unloading end under the component force of its own gravity, and at the same time can increase the speed at which the pipe slides along the guide surface to improve the feeding efficiency of the feeding mechanism.

[0028] Optionally, the unloading end is provided with a blocking block, the blocking block has a blocking surface facing the loading end, and the blocking surface is provided with a buffer pad.

[0029] By adopting the above technical solution, after the pipe slides along the material guide surface to the unloading end, the pipe contacts the buffer pad, so that the buffer pad buffers the pipe, thereby reducing the impact of the pipe on the blocking block, thereby ensuring the connection stability between the blocking block and the material guide surface, and ensuring the blocking effect of the blocking block on the pipe. At the same time, the setting of the blocking block allows the pipe to be buffered at the unloading end, so that the lifting unit of the laser pipe cutting machine can lift the pipe, avoiding the pipe moving directly from the unloading end to the lifting unit of the laser pipe cutting machine, which may cause damage to the lifting unit.

[0030] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

The feeding mechanism in the present application includes a frame, a material blocking assembly arranged on the frame and a rejection assembly arranged on the frame, the frame having a material guiding surface, the material guiding surface having a feeding end and a feeding end, the material blocking assembly and the rejection assembly are both arranged at the feeding end, the material blocking assembly can move relative to the material guiding surface, so that the material blocking assembly has a material blocking state for blocking the tube located at the feeding end and a avoidance state for forming an avoidance state with the tube located at the feeding end, the rejection assembly can move in a direction away from the feeding end and act on the tube stacked on the feeding end, so that only a single tube remains at the feeding end, thereby realizing that the feeding mechanism can only convey one tube to the laser tube cutting machine at a time, thereby avoiding the situation where manual removal of excess tubes is required, thereby avoiding the situation where manual intervention is required during the feeding process, so as to reduce the manual input when the feeding mechanism is working, thereby greatly reducing the tube cutting cost.

[0032] 2. The material baffle assembly in the present application includes a baffle and a baffle driving component arranged on a frame and used to drive the baffle to move. When the baffle is in a material baffle state, at least a portion of the baffle protrudes from the material guide surface. When the baffle is in an avoidance state, the baffle is located below the material guide surface, so that the baffle driving component only needs to drive the baffle in a single direction, thereby simplifying the movement trajectory of the baffle, reducing the control program of the feeding mechanism, and further reducing the production cost of the feeding mechanism and the stability of the feeding mechanism during operation.

[0049] Reference Figures 1 to 4A feeding mechanism for a laser tube cutting machine includes a frame 1, a material blocking assembly 2 arranged on the frame 1, and a rejection assembly 3 arranged on the frame 1. The frame 1 has a material guiding surface 111, and the material guiding surface 111 has a feeding end and a unloading end. The material blocking assembly 2 and the rejection assembly 3 are both arranged at the feeding end. The material blocking assembly 2 can move relative to the material guiding surface 111, so that the material blocking assembly 2 has a material blocking state for blocking the tube located at the feeding end and a avoidance state for forming an avoidance state with the tube located at the feeding end. The rejection assembly 3 can move in a direction away from the unloading end and act on the tubes stacked on the feeding end, so that only a single tube at the feeding end remains.

[0050] When the feeding mechanism in the present application is used to feed the pipe, the material belt 41 of the material belt storage bin assembly 4 is wound up so that the pipe moves to the feeding end under the action of the material belt 41. At this time, the material blocking assembly 2 blocks the pipe so that only one pipe can stay at the feeding end. If at least two pipes are stacked on the feeding end, the rejection assembly 3 is started to move the rejection assembly 3 and reject the pipe on the upper layer, so that the pipe on the upper layer re-enters the material belt storage bin assembly 4, and then the material blocking assembly 2 moves to move the material blocking assembly 2 to the avoidance state, so that the material blocking assembly 2 and the pipe form an avoidance state, and the pipe can move to the unloading end, and then the lifting unit of the laser pipe cutting machine lifts the pipe to complete the feeding of the pipe.

[0051] The feeding mechanism in the present application realizes that the feeding mechanism can only deliver one tube to the laser tube cutting machine at a time through the setting of the material blocking component 2 and the rejection component 3, thereby avoiding the need to manually reject excess tubes, thereby avoiding the need for human intervention in the feeding process, reducing the manual input when the feeding mechanism is working, and thus greatly reducing the tube cutting cost.

[0052] The present application does not specifically limit the formation method of the material guide surface 111. Preferably, refer to Figure 1 and Figure 3 A material guiding rod 11 is provided on one side of the frame 1 , and a top end surface of the material guiding rod 11 forms a material guiding surface 111 .

[0053] Better, refer to Figure 1 Mounting planes are provided on opposite sides of the first end of the material guide rod 11, and the material blocking assembly 2 and the rejection assembly 3 are respectively arranged on the two mounting planes to increase the connection area between the material blocking assembly 2 and the rejection assembly 3 and the frame 1, thereby increasing the connection stability between the material blocking assembly 2 and the rejection assembly 3 and the frame 1.

[0054] In other embodiments, a box structure is disposed on one side of the frame 1 , and a top surface of the box structure forms a material guiding surface 111 .

[0055] The present application does not specifically limit the structure of the frame 1. Preferably, refer to Figure 1 and Figure 3 The frame 1 is an integrated welded frame structure, which is convenient for transporting the feeding mechanism, avoiding the need for on-site assembly and debugging by customers, and improving the customer's experience. At the same time, the integrated welded frame structure is also convenient for the reasonable arrangement of cables and air pipes to increase the compactness of the feeding mechanism. In other embodiments, the frame 1 can also be a detachable structure assembled by fasteners.

[0056] The present application does not specifically limit the number of the blocking components 2 and the rejecting components 3. Preferably, the blocking components 2 and the feeding components 3 are each provided with three groups, so as to simplify the structure of the feeding mechanism while ensuring that the feeding mechanism can feed pipes of different lengths, so as to further reduce the production cost of the feeding mechanism. In other embodiments, the blocking components 2 and the rejecting components 3 can also be provided with two groups, and the two groups of the blocking components 2 and the two groups of the rejecting components 3 can slide relative to the frame 1 in a direction of approaching or moving away from each other, so as to ensure that the feeding mechanism can feed pipes of different lengths; or, the number of the blocking components 2 and the rejecting components 3 can also be more than three groups.

[0057] The present application does not specifically limit the structure of the material blocking assembly 2, and it can adopt any one of the following embodiments:

[0058] Embodiment 1. In this embodiment, referring to Figures 1 to 3 The material baffle assembly 2 includes a baffle 21 and a baffle driving member 22 disposed on the frame 1 and used to drive the baffle 21 to move. When the baffle 21 is in the material baffle state, at least a portion of the baffle 21 protrudes from the material guide surface 111. When the baffle 21 is in the avoidance state, the baffle 21 is located below the material guide surface 111.

[0059] When only a single pipe is left at the feeding end, the baffle driving member 22 is started, and then the baffle 21 is moved to the bottom of the guide surface 111 under the action of the baffle driving member 22, so that the baffle 21 and the pipe at the feeding end are avoided, so that the pipe can move along the guide surface 111 to the unloading end. In this process, the baffle 21 only needs to move in a single direction, thereby simplifying the movement trajectory of the baffle 21, reducing the control program of the feeding mechanism, and further reducing the production cost of the feeding mechanism and the stability during operation.

[0060] It should be noted that the above-mentioned “the baffle plate 21 is located below the material guiding surface 111 ” means that the baffle plate 21 is located below the corresponding position of the material guiding surface 111 .

[0061] In a preferred embodiment, referring to Figure 2 and Figure 3The frame 1 is provided with a movable plate 12 and an adjusting unit 121. The adjusting unit 121 acts on the movable plate 12 so that the movable plate 12 can move in a direction close to or away from the feeding end. The baffle 21 and the baffle driving member 22 are provided on the movable plate 12.

[0062] When loading pipes of different types, operate the adjustment unit 121 to adjust the movable plate 12, so that the distance between the end of the baffle 21 away from the unloading end and the end of the loading end can just accommodate a single pipe, so that when the belt-type storage bin assembly 4 transports the pipes, only a single pipe can stay at the loading end, thereby increasing the flexibility of the loading mechanism while ensuring that the loading mechanism can only transport a single pipe to the laser pipe cutting machine each time, thereby enabling the loading mechanism to load pipes of various types.

[0063] The present application does not make any specific limitation on the adjustment unit 121. Preferably, the adjustment unit 121 includes an adjustment shaft rotatably connected to the frame 1 and an adjustment block threadedly connected to the adjustment shaft, and a rotating wheel is provided at one end of the adjustment shaft, and the adjustment block is fixedly connected to the movable plate 12, so that when the staff rotates the rotating wheel, the rotating wheel drives the adjustment shaft to rotate, and the adjustment shaft and the adjustment block rotate relative to each other, so that the adjustment block drives the movable plate 12 to move axially along the adjustment shaft, so as to adjust the distance from the end of the baffle 21 away from the unloading end to the end of the loading end. In this process, only the rotating wheel needs to be rotated, thereby achieving the effect of facilitating the adjustment of the movable plate 12.

[0064] Preferably, multiple groups of adjusting units 121 are provided corresponding to the material blocking components 2, and the multiple groups of adjusting units 121 are connected by a rotating shaft transmission so that the multiple groups of adjusting units 121 can move synchronously. On the one hand, it is convenient to adjust the multiple baffles 21, and on the other hand, the movement speed and stroke of the multiple baffles 21 are kept consistent to ensure the blocking effect on the pipe.

[0065] In other implementation examples, the adjustment unit 121 may also include a rack fixedly connected to the movable plate 12 and a gear rotatably connected to the frame 1. The gear and the rack are meshed and transmitted, and a rotating rod is provided on the end face of the gear to facilitate the staff to rotate the gear. At the same time, the teeth of the corresponding gear of the frame 1 are provided with a ratchet that can lock the gear in both directions to increase the stability of the movable plate 12.

[0066] Preferably, a guide structure is further provided between the movable plate 12 and the frame 1. For example, the frame 1 is provided with a guide rail 112, and the movable plate 12 is provided with a guide block slidably matched with the guide rail 112 to increase the stability of the movable plate 12 when sliding.

[0067] Preferably, a guide structure is also provided between the baffle 21 and the movable plate 12 to increase the stability of the baffle 21 during movement and to increase the stability of the baffle 21 when blocking the pipe.

[0068] Further, see Figure 2 The frame 1 is provided with a scale 13 , and a scale pointer 122 pointing to the scale 13 is provided on the side of the movable plate 12 .

[0069] When the operating adjustment unit 121 is used to adjust the relative position of the baffle 21 and the feeding end, the movable plate 12 drives the scale pointer 122 to move so that the scale pointer 122 and the scale ruler 13 move relative to each other. When the scale pointer 122 points to the scale to be adjusted, the operating adjustment unit 121 is stopped, thereby achieving the effect of facilitating the adjustment of the baffle 21 to the accurate position, saving the staff time for adjusting the relative position of the baffle 21 and the feeding end, and greatly improving the feeding efficiency of the feeding mechanism.

[0070] In a preferred embodiment, referring to Figure 2 The end of the baffle 21 away from the unloading end is provided with a sensing switch 211, a sensing plate 212 and an elastic member 213 acting on the sensing plate 212. The pipe located at the loading end applies pressure to the sensing plate 212 toward the unloading end, so that the elastic member 213 undergoes elastic deformation and the sensing plate 212 triggers the sensing switch 211.

[0071] Specifically, the induction switch 211 is connected to the drive structure signal of the belt type storage bin assembly 4 .

[0072] After the pipe is conveyed to the loading end, the pipe at the loading end contacts the sensing plate 212 and applies pressure toward the second end to the sensing plate 212, so that the sensing plate 212 applies pressure to the elastic member 213, and the elastic member 213 undergoes elastic deformation, thereby causing the sensing plate 212 to trigger the sensing switch 211. At this time, the sensing switch 211 sends a signal to the material belt type storage bin assembly 4 to cause the material belt type storage bin assembly 4 to move in the opposite direction, thereby resetting the material belt type storage bin assembly 4 to complete the loading of the material at the loading end, thereby increasing the automation level of the loading mechanism.

[0073] The present application does not make any specific limitation on the triggering form of the sensing plate 212 on the sensing switch 211. It can be triggered by the sensing plate 212 blocking the sensing switch 211, or it can be triggered by the sensing plate 212 contacting the sensing switch 211. As long as the sensing plate 212 can trigger the sensing switch 211 when it moves to the position where the sensing switch 211 is located, it will be sufficient.

[0074] The present application does not specifically limit the structure of the elastic member 213. Preferably, the elastic member 213 is an elastic rod to increase the stability of the sensing plate 212 and prevent the sensing plate 212 from accidentally triggering the trigger switch. In other implementation examples, the elastic member 213 may also be an elastic column or other elastically deformable structure.

[0075] The present application does not specifically limit the structure of the baffle driver 22. Preferably, the baffle driver 22 is a cylinder to increase the stability of driving the baffle 21. In other embodiments, the baffle driver 22 can also be an electric push rod, a hydraulic cylinder, or a drive structure in which a motor cooperates with a gear rack.

[0076] Embodiment 2. In this embodiment, the material blocking assembly 2 includes a material blocking arm rotatably connected to the frame 1 and a material blocking driving member driving the material blocking arm to rotate. The material blocking arm has a blocking block that can protrude from the feeding slope so that when the material blocking driving member drives the material blocking arm, the blocking block switches back and forth between the material blocking state and the avoidance position.

[0077] In this embodiment, a movable plate 12 may also be provided to adjust the relative position of the stopper and the first end, which may also increase the flexibility of the feeding mechanism.

[0078] The present application does not specifically limit the structure of the rejection component 3. Preferably, refer to Figure 1 and Figure 4 The rejecting assembly 3 includes a rejecting plate 31, a first driving member 32 for driving the rejecting plate 31 to move in a direction close to or away from the feeding end, and a second driving member 33 provided on the frame 1 and used for driving the first driving member 32 to move in a direction close to or away from the material guiding surface 111.

[0079] When there are at least two stacked pipes at the feeding end, the second driving member 33 is started, and the second driving member 33 drives the first driving member 32 to move the first driving member 32 in a direction away from the material guiding surface 111, and finally a distance of a single pipe is left between the bottom of the rejection plate 31 and the material guiding surface 111, and then the first driving member 32 is started again, and the first driving member 32 drives the rejection plate 31 to move in a direction away from the unloading end, so that the rejection plate 31 drives the pipes on the upper layer, so that the pipes on the upper layer are separated from the feeding end and move into the storage unit, so as to complete the rejection of excess pipes. By setting the second driving member 33, the distance between the bottom of the rejection plate 31 and the material guiding surface 111 can be adjusted, so that the rejection plate 31 can reject various types of pipes, so as to ensure that the feeding mechanism can only convey a single pipe to the laser pipe cutting machine at a time, thereby ensuring the feeding efficiency of the feeding mechanism, further avoiding the situation where the staff need to reject the pipes, and ensuring the flexibility of the feeding mechanism.

[0080] In a preferred embodiment, referring to Figure 4 The first driving member 32 is provided with a connecting seat 321 , and the driving end of the second driving member 33 is connected to the connecting seat 321 .

[0081] Since the driving end of the second driving member 33 is connected to the connecting seat 321, and the first driving member 32 is arranged on the connecting seat 321, that is to say, the second driving member 33 drives the connecting seat 321 so that the connecting seat 321 drives the first driving member 32 to move, thereby avoiding the situation where the second driving member 33 needs to be connected to the first driving member 32, which may cause damage to the first driving member 32, thereby reducing the assembly difficulty of the feeding mechanism and ensuring the service life of the feeding mechanism.

[0082] Better, refer to Figure 4 The frame 1 is provided with a mounting seat 14, and the second driving member 33 is provided on the mounting seat 14. A guiding structure is also provided between the mounting seat 14 and the connecting seat 321 to guide the connecting seat 321, thereby increasing the stability of the first driving member 32 and avoiding damage to the second driving member 33, thereby increasing the service life of the feeding mechanism and reducing the failure rate of the feeding mechanism.

[0083] The present application does not specifically limit the structure of the first driving member 32. Preferably, refer to Figure 4 The first driving member 32 is a cylinder, and the rejecting plate 31 is arranged on the piston rod of the cylinder to provide power for the first driving member 32 and increase the stability of driving the rejecting plate 31. In other embodiments, the first driving member 32 can also be an electric push rod or a hydraulic cylinder, etc.

[0084] The present application does not specifically limit the structure of the second driving member 33. Preferably, refer to Figure 4 The second driving member 33 is an adjustable cylinder to provide power for the second driving member 33 and facilitate the control of the driving stroke of the second driving member 33 to simplify the control procedure of the feeding mechanism, thereby increasing the stability of the feeding mechanism and reducing the control cost of the feeding mechanism.

[0085] The present application does not specifically limit the installation position of the second driving member 33. Preferably, refer to Figure 1 The second driving member 33 is disposed below the material guiding surface 111 to increase the compactness of the loading mechanism and reduce the volume of the loading mechanism. In other embodiments, the second driving member 33 can also be disposed above the material guiding surface 111 at intervals.

[0086] In other embodiments, the reject assembly 3 may further include a reject plate located above the first end and a reject drive member for driving the reject plate to rotate, a plurality of reject rods are provided on the peripheral side of the reject plate, and the distance between the reject plate and the first end can be adjusted so that the distance between the reject rod and the first end can just accommodate a single tube, so that when the reject plate rotates, the reject rod can reject the tubes stacked on the first end.

[0087] The present application does not specifically limit the structure of the material guide surface 111. Preferably, refer to Figure 1 and Figure 3 The unloading end is inclined and extends downward from the loading end, that is, the guide surface 111 is inclined, so that after the blocking component 2 and the pipe located at the loading end form an avoidance, the pipe located at the loading end can slide along the guide surface 111 to the unloading end under the component force of its own gravity, thereby avoiding the need to set up other mechanisms to transport the pipes, reducing the driving structure required for the loading mechanism, and further reducing the production cost of the loading mechanism and the energy consumption of the loading mechanism.

[0088] In other embodiments, the material guiding surface 111 may also be arranged horizontally.

[0089] In a preferred embodiment, referring to Figure 1 and Figure 3 , a rolling wheel 214 is provided at the feeding end; and / or, a guide rail 112 is provided on the guiding surface 111 .

[0090] Preferably, rolling wheels 214 are provided at the feeding end and the top of the baffle 21, and a guide rail 112 is provided on the guide surface 111 to reduce the friction between the pipe and the guide surface 111 and the baffle 21, thereby ensuring that the pipe can slide along the guide surface 111 to the unloading end under the component force of its own gravity, and at the same time can increase the speed at which the pipe slides along the guide surface 111, so as to improve the feeding efficiency of the feeding mechanism.

[0091] In a preferred embodiment, referring to Figure 1 and Figure 3 A material stopping block 113 is provided at the unloading end. The material stopping block 113 has a material stopping surface facing the loading end, and a buffer pad 114 is provided on the material stopping surface.

[0092] After the pipe slides along the material guide surface 111 to the unloading end, the pipe contacts the buffer pad 114, so that the buffer pad 114 buffers the pipe to reduce the impact of the pipe on the blocking block 113, thereby ensuring the connection stability between the blocking block 113 and the material guide surface 111, and ensuring the blocking effect of the blocking block 113 on the pipe. At the same time, the setting of the blocking block 113 allows the pipe to buffer at the unloading end so that the lifting unit of the laser pipe cutting machine can lift the pipe, avoiding the pipe moving directly from the unloading end to the lifting unit of the laser pipe cutting machine, which may cause damage to the lifting unit.

[0093] In a preferred embodiment, referring to Figure 1 and Figure 3 The material blocking surface is vertically arranged to the material guiding surface 111, so that when the lifting unit of the laser tube cutting lifts the tube, the material blocking surface can avoid the tube, so as to ensure the smoothness of the lifting of the tube by the lifting unit and the cutting efficiency of the laser tube cutting machine.

[0094] In a preferred embodiment, referring to Figure 1 and Figure 3 The feeding mechanism also includes a material belt type storage bin assembly 4 arranged on the frame 1, and the material belt type storage bin assembly 4 is located on the side of the feeding end away from the unloading end, so that the material belt type storage bin assembly 4 can transport the pipe to the feeding end.

[0095] In a preferred embodiment, referring to Figure 3 The material belt type storage bin assembly 4 includes a material belt 41, a steering wheel 42 rotatably connected to the first end, a winding wheel 43 rotatably connected to the frame 1 and located at the bottom of the steering wheel 42, and a rotating driving member 44 for driving the winding wheel 43 to rotate. One end of the material belt 41 is arranged at the end of the frame 1 away from the second end, and the other end of the material belt 41 bypasses the steering wheel 42 and is arranged on the winding wheel 43.

[0096] Specifically, the connection position between the end of the material belt 41 away from the winding wheel 43 and the frame 1 is higher than the position of the steering wheel 42 to ensure that when the material belt 41 is wound by the winding wheel 43, the pipe on the material belt 41 can move to the loading end.

[0097] When using the feeding mechanism, first place the bundled pipes on the material belt 41, and then break the bundles of the pipes. When feeding is required at the feeding end, start the rotating drive member 44, and the rotating drive member 44 drives the winding wheel 43 to make the winding wheel 43 wind up the material belt 41, and then gradually shorten the unwound part of the material belt 41, so that the pipes are gradually raised. When the pipes move to the position of the steering wheel 42, the pipes move to the feeding end under the action of the material belt 41 to complete the feeding of the feeding end.

[0098] In a preferred embodiment, referring to Figure 1The material belt 41, the steering wheel 42 and the winding wheel 43 are all provided with a plurality of corresponding material blocking components 2 to increase the stability when the pipe is transported to the first end and ensure the feeding efficiency of the feeding mechanism.

[0099] Furthermore, the multiple winding wheels 43 are connected via a transmission shaft, and the rotating driving member 44 is connected to the transmission shaft, so that the multiple winding wheels 43 share a driving structure to ensure the synchronous movement of the multiple material strips 41, while reducing the production cost of the feeding mechanism.

[0100] The present application does not specifically limit the structure of the rotating drive member 44. Preferably, the rotating drive member 44 is a stepper motor, which is connected to the transmission shaft through a reducer to increase the transmission accuracy of the rotating drive member 44. In other embodiments, the rotating drive member 44 can also be a rotary motor or other structure that can provide rotational force.

[0101] In a preferred embodiment, referring to Figure 1 One end of the frame 1 is aligned with a plate 15, and the alignment plate 15 is arranged corresponding to the storage unit so that the pipes placed in the storage unit are in contact with the alignment plate 15, so that one ends of multiple pipes are in a flush state, so that the clamping mechanism of the laser pipe cutting machine can clamp the pipes conveyed by the feeding mechanism, thereby improving the cutting efficiency of the laser pipe cutting machine.

[0103] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.
