Description

[0001] The present application is a divisional application, the original application date is May 30, 2025, the original application number is 2025107154085, and the original application name is an automatic feeding device for an R-S line production line of an electric dust collector. TECHNICAL FIELD

[0002] The present application relates to an R-S line production line of an electric dust collector, and particularly relates to an automatic feeding device for an electric dust collector production line. BACKGROUND

[0003] As one of the commonly used cathode lines of an electric dust collector, the R-S line has various structural forms and can be generally divided into two categories: integral assembly welding and split assembly welding. The integral assembly welding is to punch two halves on the same plate and then obtain the halves by forming and welding. The split assembly welding is to manufacture the prongs, the pipe blanks and the connecting pipes respectively and then perform assembly welding.

[0004] There are some problems to be solved in the feeding link of the current R-S line production line. At present, the feeding mode of the R-S line production line mainly relies on manual operation. Specifically, the worker needs to place the R-S line half blank on the conveying belt. This manual feeding method has obvious defects, not only consumes a large amount of labor and time cost, but also when dealing with larger electric dust collector R-S lines, due to the large volume and weight of the half blank, the worker has difficulty in placing it on the conveying belt, which greatly affects the production efficiency and the labor intensity of the worker. In addition to manual feeding, there is another feeding mode in the existing technical solution, that is, the half blanks are directly stacked first and then pushed out one by one. However, this scheme also has many problems. Since the half blanks are stacked layer by layer, when the lowermost half blank needs to be pushed out, it will be pressed by the upper half blanks, making it difficult to push out. Moreover, in the process of pushing out, friction and wear will occur between the upper half blanks and the half blank that needs to be pushed out, which not only increases the pushing resistance, but also causes unnecessary damage to the pushed-out half blank, affecting the quality of the product and the stability of the production. SUMMARY

[0005] In order to overcome the slow feeding of the pipe blank half blank in the prior art, the present application provides an automatic feeding device for an electric dust collector production line, which can realize the rapid feeding of the pipe blank half blank.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: an automatic feeding device for an electric dust collector production line, comprising: a stacking frame, which is provided with a discharge port at the bottom, and a plurality of pipe blank half blanks are stacked in the stacking frame, the pipe blank half blank comprises a half pipe portion and side edge portions located on opposite sides of the half pipe portion, and the side edge portions of two adjacent layers are arranged at intervals; The first pushing mechanism is arranged at a position corresponding to the discharge port and is used for pushing the pipe blank semi-raw material located at the bottom of the stacking frame out; The blanking control mechanism comprises a limiting gear and a driving assembly used for controlling intermittent rotation of the limiting gear, the limiting gear is rotationally connected to the stacking frame and located at one side of the pipe blank semi-raw material, the pitch of the limiting gear is matched with the interval distance between the upper and lower two side portions, and one tooth of the limiting gear supports one side portion.

[0007] After the above technical scheme is adopted, the application has the following advantages: the intermittent rotation of the limiting gear is controlled by the driving assembly, so that the pipe blank semi-raw material moves downward, the lowermost pipe blank semi-raw material falls into the discharge port after losing the limitation of the limiting gear, at this time, the first pushing mechanism pushes the pipe blank semi-raw material located at the bottom of the stacking frame out of the discharge port, and the feeding of the pipe blank semi-raw material is realized. The design of the scheme changes the traditional manual feeding mode, realizes the automatic pushing and conveying of the pipe blank semi-raw material through the automatic feeding device, and workers do not need to manually place the semi-raw material on the conveying belt, which greatly reduces the labor input, reduces the labor cost, relieves the labor intensity of the workers, and avoids the difficulties and risks that the workers may face when carrying the large electric dust collector R-S line semi-raw material. Since the upper and lower two side portions in the stacking frame are arranged at intervals, and the pitch of the limiting gear is matched with the interval distance, the semi-raw materials will not be pressed and rubbed with each other during the pushing of the pipe blank semi-raw material, which effectively avoids the damage of the semi-raw material due to abrasion, ensures the quality of the product and the stability of the production, and solves the problems of raw material waste and reduced production efficiency caused by product damage.

[0008] Further, the driving assembly comprises a fixed block, a moving block, a fixed rack, a sliding rack, a first spring and a second spring, the fixed block is fixed with the stacking frame, the fixed rack and the sliding rack are arranged side by side in the moving block, the fixed rack is fixed with the moving block, the sliding rack is slidingly connected with the moving block and has a first position and a second position, the second spring is arranged between the sliding rack and the moving block to keep the sliding rack in the first position, the moving block is slidingly connected with the fixed block and has a locking position for engaging the fixed rack with the limiting gear and an unlocking position for engaging the sliding rack with the limiting gear, the first spring is arranged between the fixed block and the moving block to keep the moving block in the locking position, the end of the telescopic rod is provided with a first abutting block extending to the front side of the moving block, when the sliding rack is switched from the first position to the second position, the sliding rack moves a pitch distance, and when the telescopic rod of the first pushing mechanism is retracted, the first abutting block of the telescopic rod abuts and drives the moving block to move to the unlocking position.

[0009] The specific steps are as follows: when the telescopic rod of the first pushing-out mechanism is retracted after the pushing action, the telescopic rod abuts against and pulls the moving block to move to the unlocking position (the limit gear and the sliding gear are engaged), at this time, the first spring is in the stretched state, and the sliding gear is rotated by one tooth under the action of the gravity of the pipe blank half-piece, so that the sliding gear moves downward by one tooth and touches the bottom wall of the sliding groove where the sliding gear is located, that is, the second position of the sliding gear, and the second spring is compressed at this time, and the lowermost pipe blank half-piece falls to the discharge port after losing the limitation of the limit gear, and the discharging action is completed. Then the first spring pulls the moving block to move to the locking position (the limit gear and the fixed gear are engaged), and at this time, the second spring is stretched to push the moving gear to the initial first position.

[0010] One tooth of the limit gear supports the pipe blank half-piece, and only when the sliding gear is switched and engaged with the limit gear, the pipe blank half-piece is released, thereby effectively avoiding the situation of multiple discharging or inaccurate discharging, and ensuring the accuracy and stability of the feeding. By means of the design that the telescopic rod of the first pushing-out mechanism abuts against and moves the moving block to the unlocking position when the telescopic rod is retracted, the automatic triggering of the discharging is realized. Without additional control system or manual intervention, the whole feeding process is more automatic and smooth, the workload and error probability of manual operation are reduced, the production efficiency is improved, and the falling of the pipe blank half-piece is more stable, and the limit gear can be accurately triggered to rotate after the telescopic rod is retracted, so that the corresponding pipe blank half-piece falls to the specified position.

[0011] Further, the driving assembly comprises a fixed block, a moving block, a fixed gear, a sliding gear and a second spring, the fixed block is fixed with the stacking frame, the fixed gear and the sliding gear are arranged side by side in the moving block, the fixed gear is fixed with the moving block, the sliding gear is slidingly connected with the moving block and has a first position and a second position, the second spring is arranged between the sliding gear and the moving block to keep the sliding gear in the first position, the moving block is slidingly connected with the fixed block and has a locking position at which the fixed gear is engaged with the limit gear and an unlocking position at which the sliding gear is engaged with the limit gear, when the sliding gear is switched from the first position to the second position, the sliding gear moves by a tooth distance, the telescopic rod is provided with a first abutting block and a second abutting block along the telescopic direction, one side of the moving block is arranged between the first abutting block and the second abutting block, when the telescopic rod of the first pushing-out mechanism is retracted, the first abutting block abuts against and moves the moving block to the unlocking position, and when the telescopic rod of the first pushing-out mechanism is extended, the second abutting block abuts against and moves the moving block to the locking position.

[0012] The first abutting block and the second abutting block are arranged on the telescopic rod, so that the telescopic rod can control the moving block when the telescopic rod is retracted and extended. When the telescopic rod is retracted, the first abutting block moves the moving block to the unlocking position; when the telescopic rod is extended, the second abutting block moves the moving block to the locking position. The bidirectional control mode makes the position switching of the moving block more accurate and stable, and can better ensure the meshing state of the limiting gear, thereby improving the accuracy and stability of the feeding. Since the position switching of the moving block does not need to rely on the elastic force of the elastic member, the influence of the fatigue and deformation of the elastic member on the system performance is avoided, thereby enhancing the stability and reliability of the entire automatic feeding device and reducing the occurrence of inaccurate feeding or equipment failure caused by the failure of the elastic member.

[0013] Further, one of the first abutting block and the second abutting block is in abutment with the moving block, and the other is spaced apart from the moving block.

[0014] The foregoing technical scheme prevents the two abutting blocks from being in contact with the moving block at the same time during the extension and retraction of the telescopic rod, thereby preventing interference with the normal movement of the moving block and the meshing state of the limiting gear, ensuring that only one abutting block acts on the moving block each time, and enabling the moving block to accurately switch between the locking position and the unlocking position according to the design requirements.

[0015] Further, the fixed block is provided with a sliding groove, and the moving block is adapted to the sliding groove and is slidingly connected in the sliding groove.

[0016] The foregoing technical scheme provides a clear movement track for the moving block, so that the moving block can only move along the direction of the sliding groove, thereby ensuring the accuracy and stability of the movement of the moving block. Moreover, the sliding groove can position the moving block, thereby achieving accurate control of the feeding and discharging. The adaptive connection between the moving block and the sliding groove enhances the connection stability between the fixed block and the moving block.

[0017] Further, the discharging control mechanism further comprises at least one second gear, the second gear is rotationally connected to the stacking rack, the second gear and the limiting gear are spaced apart along the extension and retraction direction of the telescopic rod, and the second gear and the limiting gear are coaxially fixed through shaft coupling.

[0018] The second gear is arranged to increase the contact points with the side edge of the pipe blank half-piece, so that the whole limiting and blanking process is more stable, and the pipe blank half-piece is prevented from tilting during movement. When the limiting gear supports the pipe blank half-piece, the second gear can also play an auxiliary supporting role to share the stress of the limiting gear, prevent the limiting gear from being damaged or deformed due to excessive stress, and improve the stability and reliability of the blanking control mechanism. For example, in the case of a large number of pipe blank half-pieces and long length, the second gear can work together with the limiting gear to better limit the movement of the pipe blank half-piece and ensure the accuracy of blanking.

[0019] Further, the number of the blanking control mechanisms is two, and the two blanking control mechanisms are arranged on opposite sides of the feeding device.

[0020] With the foregoing technical scheme, the two blanking control mechanisms limit and control the pipe blank half-pieces from opposite sides, so that the position of the pipe blank half-pieces in the stacking rack is more stable. Compared with a single blanking control mechanism, the control on both sides can better balance the force acting on the pipe blank half-pieces, prevent the pipe blank half-pieces from tilting or deviating due to uneven force, and ensure the stability of the feeding process. For example, when the pipe blank half-pieces are pushed out, the blanking control mechanisms on both sides can work synchronously to smoothly push the pipe blank half-pieces out of the bottom of the stacking rack, reducing the possibility of damage to the pipe blank half-pieces due to unilateral force.

[0021] Further, the bottom of the stacking rack is provided with a positioning groove matched with the half-pipe part and a supporting surface matched with the side edge part. The positioning groove extends along the extension direction of the first pushing mechanism, and the end opening of the positioning groove in the direction is provided.

[0022] With the foregoing technical scheme, when the pipe blank half-pieces in the stacking rack are stacked in the forward direction, the half-pipe part is located above and outside the positioning groove, and the supporting surface supports the side edge part, so that the pipe blank half-pieces can be positioned only by the supporting surface; when the pipe blank half-pieces in the stacking rack are stacked in the reverse direction, the half-pipe part is located in the positioning groove, and the supporting surface supports the side edge part, so that the positioning of the pipe blank half-pieces is completed by the positioning groove and the supporting surface. Through the positioning groove and the supporting surface, the pipe blank half-pieces stacked in the forward direction or the reverse direction can be accurately positioned at the discharge port, so that when the pipe blank half-pieces are pushed out of the discharge port by the first pushing mechanism, the pipe blank half-pieces will not shake.

[0023] Further, the second pushing mechanism and a guide frame are further included. The guide frame and the first pushing mechanism are located on opposite sides of the discharge port. The first pushing mechanism is used to push the pipe blank half-pieces at the bottom of the stacking rack to the guide frame. The second pushing mechanism is arranged at a position corresponding to the guide frame and is used to push the pipe blank half-pieces on the guide frame to the feeding station. The pushing directions of the first pushing mechanism and the second pushing mechanism are perpendicular.

[0024] With the foregoing technical scheme, the guide frame provides a stable transition position for the pipe blank semi-workpiece. The pipe blank semi-workpiece can be better supported and positioned on the guide frame, reducing the possibility of damage to the pipe blank semi-workpiece due to instability during pushing. The vertical pushing mode of the first pushing mechanism and the second pushing mechanism makes the force on the pipe blank semi-workpiece more uniform during transfer, further enhancing the stability of the feeding. For example, when pushing a pipe blank semi-workpiece of large size or heavy weight, the guide frame and the vertical pushing mode can effectively prevent the pipe blank semi-workpiece from tilting or falling, ensuring the stable progress of the feeding process.

[0025] Further, the side wall of the stacking frame is provided with a notch near the bottom, and the limiting gear is arranged at the notch position and passes through the notch.

[0026] With the foregoing technical scheme, the notch allows the limiting gear to directly contact the pipe blank semi-workpiece in the stacking frame, facilitating the limiting and control of the pipe blank semi-workpiece by the limiting gear. The limiting gear passes through the notch and can accurately support the side edge of the pipe blank semi-workpiece, achieving precise control of the falling of the pipe blank semi-workpiece.

[0032] As Figures 8 to 9 shown, an R-S wire of an electric dust collector, comprising two pipe blank half pieces 1.1 and a plurality of prongs 1.2, the pipe blank half piece 1.1 comprising a half pipe portion 1.1.1 and a side edge portion 1.1.2 located on opposite sides of the half pipe portion 1.1.1, the two pipe blank half pieces 1.1 are superimposed and welded to form a pipe blank piece 1.3, the pipe blank piece 1.3 comprising a pipe blank body 1.3.0, a connecting portion 1.3.1 located at both ends of the pipe blank body 1.3.0, and a pipe blank side edge 1.3.2 located on opposite sides of the pipe blank body 1.3.0, the pipe blank side edge 1.3.2 is formed by the side edge portions 1.1.2 of the two pipe blank half pieces 1.1 being enclosed and welded, the plurality of prongs 1.2 are arranged at intervals on the pipe blank side edge 1.3.2, the prong 1.2 comprises a fixed portion 1.2.1 and a discharge portion 1.2.2, the side edge portion 1.1.2 of the two pipe blank half pieces 1.1 covers the fixed portion 1.2.1, the discharge portion 1.2.2 is provided with a discharge tip 1.2.3, and further comprising a bending portion 1.2.4 formed by bending an end of the fixed portion 1.2.1 of the prong 1.2 close to the half pipe portion 1.1.1.

[0033] As Figures 1 to 7 shown, the application provides an automatic feeding device for an electric dust collector production line, comprising: a stacking rack 7.1 provided with a discharge opening 7.5 at the bottom, a plurality of pipe blank half pieces 1.1 are stacked in the stacking rack 7.1, the pipe blank half piece 1.1 comprising a half pipe portion 1.1.1 and a side edge portion 1.1.2 located on opposite sides of the half pipe portion 1.1.1, and the stacking rack 7.1 is provided with a side edge portion 1.1.2 at intervals between two adjacent side edge portions 1.1.2; a first pushing mechanism 7.2 arranged at a position corresponding to the discharge opening 7.5, for pushing the pipe blank half piece 1.1 located at the bottom of the stacking rack 7.1 out; a discharging control mechanism 8 comprising a limiting gear 8.7 and a driving assembly for controlling the intermittent rotation of the limiting gear 8.7, the limiting gear 8.7 is rotationally connected to the stacking rack 7.1 and located on one side of the pipe blank half piece 1.1, the limiting gear 8.7 is provided with a tooth spacing adapted to the interval distance between two adjacent side edge portions 1.1.2, and one of the teeth of the limiting gear 8.7 supports one of the side edge portions 1.1.2.

[0034] By adopting the technical scheme, the application has the following advantages: the driving assembly controls the intermittent rotation of the limiting gear 8.7, so that the pipe blank semi-blanks 1.1 move downward, and the lowermost pipe blank semi-blank 1.1 falls into the discharge port 7.5 after losing the limitation of the limiting gear 8.7; at this time, the first pushing mechanism 7.2 pushes the pipe blank semi-blank 1.1 at the bottom of the stacking rack 7.1 out of the discharge port 7.5, so as to realize the feeding of the pipe blank semi-blank 1.1. The design of the scheme changes the traditional manual feeding mode, realizes the automatic pushing and conveying of the pipe blank semi-blank 1.1 through the automatic feeding device 7, and workers do not need to manually place the semi-blank on the conveying belt, which greatly reduces the labor input and labor cost, and also reduces the labor intensity of workers and avoids the difficulties and risks that workers may face when carrying the large semi-blank of the electric dust collector R-S line 1. Since the upper and lower two adjacent side portions 1.1.2 in the stacking rack 7.1 are arranged at intervals, and the pitch of the limiting gear 8.7 is adapted to the interval, the semi-blanks will not be pressed and rubbed with each other during the pushing of the pipe blank semi-blank 1.1, so that the damage of the semi-blanks due to abrasion is effectively avoided, the quality and stability of the product are ensured, and the problems of raw material waste and reduced production efficiency caused by product damage are reduced.

[0035] Specifically, the upper and lower two adjacent semi-tube portions 1.1.1 of the pipe blank semi-blanks 1.1 in the stacking rack 7.1 are tightly stacked, and there is a gap between the semi-tube portion 1.1.1 of the pipe blank semi-blank 1.1 located at the discharge port 7.5 and the semi-tube portion 1.1.1 of the pipe blank semi-blank 1.1 limited by the limiting gear 8.7, and the first pushing mechanism 7.2 is a pneumatic cylinder.

[0036] In one of the embodiments, as shown in Figures 3 to 6 and Figure 10As shown, the driving assembly comprises a fixed block 8.1, a moving block 8.2, a fixed rack 8.3, a sliding rack 8.4, a first spring 8.5 and a second spring 8.6, the fixed block 8.1 is fixed with the stacking frame 7.1, the fixed rack 8.3 and the sliding rack 8.4 are arranged side by side on the moving block 8.2, the fixed rack 8.3 is fixed with the moving block 8.2, the sliding rack 8.4 is slidingly connected with the moving block 8.2 and has a first position and a second position, the second spring 8.6 is arranged between the sliding rack 8.4 and the moving block 8.2 to keep the sliding rack 8.4 in the first position, the moving block 8.2 is slidingly connected with the fixed block 8.1 and has a locking position for engaging the fixed rack 8.3 with the limiting gear 8.7 and an unlocking position for engaging the sliding rack 8.4 with the limiting gear 8.7, the first spring 8.5 is arranged between the fixed block 8.1 and the moving block 8.2 to keep the moving block 8.2 in the locking position, when the sliding rack 8.4 is switched from the first position to the second position, the end of the telescopic rod 7.2.1 is provided with a first abutting block 7.2.2 extending to the front side of the moving block 8.2, the sliding rack 8.4 moves a tooth pitch distance, when the telescopic rod 7.2.1 of the first pushing mechanism 7.2 is retracted, the first abutting block 7.2.2 of the telescopic rod 7.2.1 abuts and drives the moving block 8.2 to move to the unlocking position.

[0037] With the foregoing technical solution, the specific steps are as follows: when the telescopic rod 7.2.1 of the first pushing mechanism 7.2 is retracted after completing the pushing action, as shown in Figures 3 to 4 , the first abutting block 7.2.2 of the telescopic rod 7.2.1 will abut and pull the moving block 8.2 to move to the unlocking position (the limiting gear 8.7 and the sliding rack 8.4 are engaged), at this time, the first spring 8.5 will be in a stretched state, because the sliding rack 8.4 is pressed by the gravity of the pipe blank half-piece 1.1 to rotate a tooth pitch distance, the sliding rack 8.4 moves downward a tooth pitch distance to touch the bottom wall of the sliding groove where the sliding rack 8.4 is located, that is, the second position of the sliding rack 8.4 (as shown in Figure 5 and Figure 6 ), at the same time, the second spring 8.6 is compressed, at this time, the lowermost pipe blank half-piece 1.1 falls to the discharge port 7.5 after losing the limitation of the limiting gear 8.7, and the discharging action is completed. Subsequently, as shown in Figures 5 to 6 , when the first abutting block 7.2.2 makes a pushing action forward with the telescopic rod 7.2.1, the limitation of the first abutting block 7.2.2 to the moving block 8.2 gradually disappears, the first spring 8.5 will gradually pull the moving block 8.2 to move to the locking position (the limiting gear 8.7 and the fixed rack 8.3 are engaged), at this time, the second spring 8.6 is stretched to push the moving rack to the initial first position (as shown in Figure 3 and Figure 4 ).

[0038] One tooth of the limiting gear 8.7 supports the pipe blank half-piece 1.1, and only when the sliding rack 8.4 switches the position and meshes with the limiting gear 8.7 to rotate, a pipe blank half-piece 1.1 is released, effectively avoiding the situation of multiple blanking or inaccurate blanking, and ensuring the accuracy and stability of the feeding. By the design that the telescopic rod 7.2.1 of the first pushing mechanism 7.2 abuts against and moves the moving block 8.2 to the unlocking position when it is retracted, the automatic triggering of blanking is realized. Without additional control system or manual intervention, the whole feeding process is more automated and smooth, reducing the workload and error probability of manual operation, improving the production efficiency, and being more stable in controlling the falling of the pipe blank half-piece 1.1, and being able to accurately trigger the rotation of the limiting gear 8.7 after the telescopic rod 7.2.1 is retracted, so that the corresponding pipe blank half-piece 1.1 falls to the designated position.

[0039] Further, the fixed block 8.1 is provided with a sliding groove 8.0, and the moving block 8.2 is adapted to and slidably connected in the sliding groove 8.0.

[0040] By adopting the foregoing technical scheme, the sliding groove 8.0 provides a clear movement track for the moving block 8.2, so that the moving block 8.2 can only move along the direction of the sliding groove 8.0, thereby ensuring the accuracy and stability of the movement of the moving block 8.2. Moreover, the sliding groove 8.0 can position the moving block 8.2, realizing accurate control of blanking and feeding. The adaptive connection of the moving block 8.2 and the sliding groove 8.0 enhances the connection stability between the fixed block 8.1 and the moving block 8.2.

[0041] Further, the blanking control mechanism 8 further comprises at least one second gear, the pitch of the second gear is adapted to the interval distance of the upper and lower two adjacent side portions 1.1.2, the second gear is rotationally connected to the stacking rack 7.1, the second gear and the limiting gear 8.7 are arranged in the extension and retraction direction of the telescopic rod 7.2.1, and the second gear and the limiting gear 8.7 are coaxially fixed through the shaft coupling 8.8.

[0042] The second gear is arranged to increase the contact points with the side edge part 1.1.2 of the pipe blank semi-blank 1.1, so that the whole limiting and blanking process is more stable, and the pipe blank semi-blank 1.1 is prevented from tilting during movement. When the limiting gear 8.7 supports the pipe blank semi-blank 1.1, the second gear can also play a supporting role, sharing the stress of the limiting gear 8.7, preventing the limiting gear 8.7 from being damaged or deformed due to excessive stress, and improving the stability and reliability of the blanking control mechanism 8. For example, in the case of a large number of pipe blank semi-blanks 1.1 and long length, the second gear can work together with the limiting gear 8.7 to better limit the movement of the pipe blank semi-blank 1.1, ensuring the accuracy of blanking. Specifically, when the limiting gear 8.7 is stationary, the lowermost pipe blank semi-blank 1.1 is jointly limited by the second gear and the limiting gear 8.7, and when the limiting gear 8.7 rotates, the second gear rotates with the limiting gear 8.7, so that the lowermost pipe blank semi-blank 1.1 loses the limitation of the second gear and the limiting gear 8.7 and falls to the discharge port 7.5.

[0043] Further, the number of the blanking control mechanisms 8 is two, and the two blanking control mechanisms 8 are arranged on opposite sides of the feeding device 7.

[0044] With the foregoing technical solutions, the two blanking control mechanisms 8 limit and control the pipe blank semi-blank 1.1 from opposite sides, so that the position of the pipe blank semi-blank 1.1 in the stacking rack 7.1 is more stable. Compared with a single blanking control mechanism 8, the control on both sides can better balance the force on the pipe blank semi-blank 1.1, preventing the pipe blank semi-blank 1.1 from tilting or deviating due to uneven stress, and ensuring the stability of the feeding process. For example, when the pipe blank semi-blank 1.1 is pushed out, the blanking control mechanisms 8 on both sides can work synchronously, so that the pipe blank semi-blank 1.1 is smoothly pushed out from the bottom of the stacking rack 7.1, reducing the possibility of damage to the pipe blank semi-blank 1.1 caused by unilateral stress.

[0045] Further, the bottom of the stacking rack 7.1 is provided with a positioning groove 7.6 matched with the semi-pipe part 1.1.1 and a support surface 7.7 matched with the side edge part 1.1.2, the positioning groove 7.6 extends along the extension direction of the first pushing mechanism 7.2, and the end opening of the positioning groove 7.6 in the direction is provided.

[0046] With the foregoing technical solutions, when the pipe blank semi-blanks 1.1 in the stacking rack 7.1 are stacked in the forward direction (as shown in FIG. 8A), Figure 2 the semi-pipe part 1.1.1 is located above and outside the positioning groove 7.6, and the support surface 7.7 supports the side edge part 1.1.2, so that the pipe blank semi-blank 1.1 can be positioned only by the support surface 7.7; when the pipe blank semi-blanks 1.1 in the stacking rack 7.1 are stacked in the reverse direction (as shown in FIG. 8B), Figure 1As shown, the semi-tube portion 1.1.1 is located within the positioning groove 7.6, and the supporting surface 7.7 supports the side portion 1.1.2. At this time, the positioning groove 7.6 and the supporting surface 7.7 complete the positioning of the tube blank semi-blank 1.1. Through the positioning groove 7.6 and the supporting surface 7.7, the tube blank semi-blank 1.1, whether stacked in the forward or reverse direction, can achieve precise vertical positioning at the discharge port 7.5, so that when the first ejection mechanism 7.2 ejects the tube blank semi-blank 1.1 from the discharge port 7.5, the tube blank semi-blank 1.1 will not wobble.

[0047] Specifically, forward stacking refers to the inner wall of the half-tube portion 1.1.1 facing downwards, and reverse stacking refers to the inner wall of the half-tube portion 1.1.1 facing upwards. The end opening allows the telescopic rod 7.2.1 of the first ejection mechanism 7.2 to enter the positioning groove 7.6 and push the tube blank half-blank 1.1 in the positioning groove 7.6 to slide out.

[0048] Furthermore, such as Figure 7 As shown, it also includes a second ejection mechanism 7.3 and a guide frame 7.4. The guide frame 7.4 and the first ejection mechanism 7.2 are located on opposite sides of the discharge port 7.5. The first ejection mechanism 7.2 is used to eject the tube blank half-blank 1.1 located at the bottom of the stacking rack 7.1 to the guide frame 7.4. The second ejection mechanism 7.3 is located at a position corresponding to the guide frame 7.4 and is used to eject the tube blank half-blank 1.1 on the guide frame 7.4 to the loading station. The pushing directions of the first ejection mechanism 7.2 and the second ejection mechanism 7.3 are perpendicular.

[0049] Using the aforementioned technical solution, the guide frame 7.4 provides a stable transition position for the tube blank half-bulk 1.1. The tube blank half-bulk 1.1 receives better support and positioning on the guide frame 7.4, reducing the possibility of damage to the tube blank half-bulk 1.1 due to instability during the pushing process. The vertical pushing method of the first pushing mechanism 7.2 and the second pushing mechanism 7.3 ensures that the force on the tube blank half-bulk 1.1 is more even during transfer, further enhancing the stability of the feeding process. For example, when pushing larger or heavier tube blank half-bulks 1.1, the guide frame 7.4 and the vertical pushing method effectively prevent the tube blank half-bulk 1.1 from tilting or falling, ensuring the stable progress of the feeding process.

[0050] Furthermore, a notch is provided on the side wall of the stacking rack 7.1 near the bottom, and the limiting gear 8.7 is located at the notch and passes through the notch.

[0051] The gap is arranged to enable the limiting gear 8.7 to directly contact the pipe blank semi-blank 1.1 in the stacking rack 7.1, facilitating the limiting and control of the pipe blank semi-blank 1.1 by the limiting gear 8.7. The limiting gear 8.7 passes through the gap and can accurately support the side edge part 1.1.2 of the pipe blank semi-blank 1.1, achieving accurate control of the falling of the pipe blank semi-blank 1.1.

[0052] In still another embodiment, as shown in Figure 10 and Figure 11 The driving assembly includes a fixed block 8.1, a moving block 8.2, a fixed rack 8.3, a sliding rack 8.4, and a second spring 8.6. The fixed block 8.1 is fixed with the stacking rack 7.1. The fixed rack 8.3 and the sliding rack 8.4 are arranged side by side on the moving block 8.2. The fixed rack 8.3 is fixed with the moving block 8.2. The sliding rack 8.4 is slidingly connected to the moving block 8.2 and has a first position and a second position. The second spring 8.6 is arranged between the sliding rack 8.4 and the moving block 8.2 to keep the sliding rack 8.4 in the first position. The moving block 8.2 is slidingly connected to the fixed block 8.1 and has a locked position for engaging the fixed rack 8.3 with the limiting gear 8.7 and an unlocked position for engaging the sliding rack 8.4 with the limiting gear 8.7. When the sliding rack 8.4 is switched from the first position to the second position, the sliding rack 8.4 moves a distance of one tooth pitch. The telescopic rod 7.2.1 is arranged with a first abutting block 7.2.2 and a second abutting block 7.2.3 at intervals along the telescopic direction. One side of the moving block 8.2 is arranged between the first abutting block 7.2.2 and the second abutting block 7.2.3. When the telescopic rod 7.2.1 of the first pushing mechanism 7.2 is retracted, the first abutting block 7.2.2 abuts and moves the moving block 8.2 to the unlocked position. When the telescopic rod 7.2.1 of the first pushing mechanism 7.2 is extended, the second abutting block 7.2.3 abuts and moves the moving block 8.2 to the locked position. Further, one of the first abutting block 7.2.2 and the second abutting block 7.2.3 abuts the moving block 8.2, and the other is arranged at intervals with the moving block 8.2. Specifically, as shown in Figure 10 The first abutting block 7.2.2 is arranged at the end of the telescopic rod 7.2.1, and the second abutting block 7.2.3 is arranged at the rear side. The moving distance L1 of the telescopic rod 7.2.1 is greater than or equal to the length of the pipe blank semi-blank 1.1, so that the pipe blank semi-blank 1.1 can be fully pushed out.

[0053] The foregoing technical scheme is adopted, the first abutting block 7.2.2 and the second abutting block 7.2.3 are arranged on the telescopic rod 7.2.1, so that the telescopic rod 7.2.1 can control the moving block 8.2 when retracting and extending. When the telescopic rod 7.2.1 retracts, the first abutting block 7.2.2 moves the moving block 8.2 to the unlocking position; when the telescopic rod 7.2.1 extends, the second abutting block 7.2.3 moves the moving block 8.2 to the locking position. This bidirectional control mode makes the position switching of the moving block 8.2 more accurate and stable, and can better ensure the meshing state of the limiting gear 8.7, thereby improving the accuracy and stability of the feeding. Since the elastic force of the elastic member is not needed to realize the position switching of the moving block 8.2, the influence of the fatigue and deformation of the elastic member on the system performance is avoided, thereby enhancing the stability and reliability of the entire automatic feeding device 7, and reducing the situation of inaccurate feeding or equipment failure caused by the failure of the elastic member. In order to prevent the two abutting blocks from contacting the moving block 8.2 at the same time during the telescopic process of the telescopic rod 7.2.1, interference is caused, the normal movement of the moving block 8.2 and the meshing state of the limiting gear 8.7 are affected, and it is ensured that only one abutting block acts on the moving block 8.2 each time, so that the moving block 8.2 can accurately switch between the locking position and the unlocking position according to the design requirements, wherein the vertical part of the first abutting block 7.2.2 is arranged to avoid the pipe blank half blank 1.1, so that the telescopic rod 7.2.1 can pull the moving block 8.2 to the unlocking position when retracting and will not interfere with the falling of the pipe blank half blank 1.1.

[0054] It can be understood that there is another embodiment, which is different from the above two embodiments in that the driving assembly is a driving motor with a brake, specifically a stepper motor, which can control the angle of gear rotation and brake at the appropriate time.

[0055] In addition to the preferred embodiments described above, the present application also has other embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.
