Description

Technical Field

[0001] This application relates to the production line of the R-S wire of an electrostatic precipitator, and particularly to an automatic feeding device for the production line of the R-S wire of an electrostatic precipitator. Background Art

[0002] As one of the commonly used cathode wires of an electrostatic precipitator, the R-S wire has various structural forms and can generally be divided into two categories: integral group welding and split group welding. Integral group welding is obtained by punching two half pieces on the same sheet and then forming and welding them together. This method has a low material utilization rate. Split group welding is to separately manufacture the barbs, tube blanks, and connecting tubes and then perform group welding.

[0003] There are some problems that need to be solved urgently in the feeding link of the current R-S wire production line. At present, the feeding method on the R-S wire production line mainly relies on manual operation. Specifically, workers need to place the semi-finished parts of the R-S wire on the conveyor belt. This manual feeding method has obvious defects. It not only consumes a large amount of labor and time costs, but also when dealing with larger R-S wires of electrostatic precipitators, due to the large volume and weight of the semi-finished parts, it is difficult for workers to smoothly place them on the conveyor belt, which greatly affects the production efficiency and the labor intensity of workers. In addition to manual feeding, there is another feeding method in the existing technical solutions, that is, first stack the semi-finished parts directly and then push them out one by one. However, this solution also has many problems. Since the semi-finished parts are stacked layer by layer, when the semi-finished part at the bottom needs to be pushed out, it will be oppressed by the semi-finished parts above, resulting in difficult pushing. And during the pushing process, there will be friction and wear between the semi-finished parts above and the semi-finished part to be pushed out, which not only increases the resistance of pushing, but also causes unnecessary damage to the pushed-out semi-finished part, affecting the product quality and production stability. Summary of the Invention

[0004] In order to overcome the deficiency of slow feeding of the tube blank semi-finished parts in the prior art, this application provides an automatic feeding device for the production line of the R-S wire of an electrostatic precipitator, which can realize the rapid feeding of the tube blank semi-finished parts.

[0005] In order to achieve the above purpose, this application adopts the following technical solutions: An automatic feeding device for the production line of the R-S wire of an electrostatic precipitator, comprising: A stacking rack, which is provided with a discharge port at the bottom. A number of tube blank semi-finished parts are stacked in the stacking rack. The tube blank semi-finished parts include a semi-tube part and side parts located on opposite sides of the semi-tube part. The side parts of two adjacent upper and lower layers in the stacking rack are spaced apart; A first pushing mechanism, which is arranged at a position corresponding to the discharge port and is used to push out the tube blank semi-finished part located at the bottom of the stacking rack; The blanking control mechanism includes a limit gear and a driving component for controlling the intermittent rotation of the limit gear. The limit gear is rotatably connected to the stacking rack and is located on one side of the semi-finished billet of the pipe blank. The pitch of the teeth of the limit gear is adapted to the interval distance between two adjacent upper and lower side parts, and one tooth of the limit gear supports one side part.

[0006] After adopting the above technical solution, the present application has the following advantages: By controlling the intermittent rotation of the limit gear through the driving component, the semi-finished billet of the pipe blank moves downward accordingly. After the lowermost semi-finished billet of the pipe blank loses the restriction of the limit gear, it will fall at the discharge port. At this time, the first pushing mechanism pushes the semi-finished billet of the pipe blank located at the bottom of the stacking rack out from the discharge port to realize the feeding of the semi-finished billet of the pipe blank. The design of this solution changes the traditional manual feeding mode. Through the automatic feeding device, the automatic pushing and conveying of the semi-finished billet of the pipe blank are realized. There is no need for workers to manually place the semi-finished billet on the conveyor belt, which greatly reduces the labor input, reduces the labor cost, and at the same time reduces the labor intensity of workers and avoids the difficulties and risks that workers may face when handling the relatively large semi-finished billet of the R-S line of the electrostatic precipitator. Since the interval between two adjacent upper and lower side parts in the stacking rack is provided, and the pitch of the teeth of the limit gear is adapted thereto, during the process of pushing out the semi-finished billet of the pipe blank, there will be no mutual compression and friction between the semi-finished billets, effectively avoiding the damage caused by wear of the semi-finished billets, ensuring the product quality and production stability, and solving the problems of raw material waste and production efficiency reduction caused by product damage.

[0007] Further, the driving component includes a fixed block, a moving block, a fixed rack, a sliding rack, a first spring and a second spring. The fixed block is fixed to the stacking rack. The fixed rack and the sliding rack are arranged side by side on the moving block. The fixed rack is fixed to the moving block. The sliding rack is slidably connected to 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 slidably connected to the fixed block and has a locking position where the fixed rack meshes with the limit gear and an unlocking position where the sliding rack meshes with the limit 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 switches from the first position to the second position, the sliding rack moves a distance equal to the pitch of one tooth. When the telescopic rod of the first pushing mechanism retracts, the first abutting block of the telescopic rod abuts against and drives the moving block to move to the unlocking position.

[0008] Adopting the foregoing technical solution, the specific steps are as follows: When the telescopic rod of the first pushing mechanism retracts after completing the material pushing action, it will abut against and pull the moving block to move to the unlocking position (the limiting gear and the sliding rack are engaged). At this time, the first spring will be in a stretched state. Due to the sliding rack being rotated by a tooth pitch under the action of the gravity of the semi-finished tube blank, the sliding rack moves downward by a tooth distance and touches the bottom wall of the sliding groove where the sliding rack is located, that is, the second position of the sliding rack. At the same time, the second spring is compressed. At this time, the lowermost semi-finished tube blank falls to the discharge port after losing the limitation of the limiting gear, completing the blanking action. Subsequently, the first spring will pull the moving block to move to the locking position (the limiting gear and the fixed rack are engaged). At this time, after the second spring extends, it will push the moving rack to the initial first position.

[0009] One tooth of the limiting gear supports the semi-finished tube blank. Only when the sliding rack switches positions and meshes with the limiting gear to rotate, will a semi-finished tube blank be released, effectively avoiding the situation of over-blanking or inaccurate blanking, and ensuring the accuracy and stability of feeding. By using the design that the telescopic rod of the first pushing mechanism abuts against and makes the moving block move to the unlocking position when retracting, the automatic triggering of blanking is realized. Without additional control systems or manual intervention, the entire feeding process becomes more automated and smooth, reducing the workload and error probability of manual operations, improving production efficiency, and being more stable when controlling the fall of the semi-finished tube blank. It can accurately trigger the rotation of the limiting gear after the telescopic rod retracts, so that the corresponding semi-finished tube blank falls to the designated position.

[0010] Further, the driving assembly includes a fixed block, a moving block, a fixed rack, a sliding rack, and a second spring. The fixed block is fixed to the stacking rack. The fixed rack and the sliding rack are arranged side by side on the moving block. The fixed rack is fixed to the moving block. The sliding rack is slidably connected to 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 slidably connected to the fixed block and has a locking position where the fixed rack meshes with the limiting gear and an unlocking position where the sliding rack meshes with the limiting gear. When the sliding rack switches from the first position to the second position, the sliding rack moves a tooth pitch distance. The telescopic rod is provided with a first abutting block and a second abutting block at intervals 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 mechanism retracts, the first abutting block abuts against and makes the moving block move to the unlocking position. When the telescopic rod of the first pushing mechanism extends, the second abutting block abuts against and makes the moving block move to the locking position.

[0011] With the foregoing technical solution, by providing a first pressing block and a second pressing block on the telescopic rod, the telescopic rod can control the moving block when retracting and extending. When the telescopic rod retracts, the first pressing block moves the moving block to the unlocking position; when the telescopic rod extends, the second pressing block moves the moving block to the locking position. This two-way control method makes the position switching of the moving block more accurate and stable, can better ensure the meshing state of the limiting gear, thereby improving the accuracy and stability of feeding. Since there is no need to rely on the elastic force of the elastic member to achieve the position switching of the moving block, the influence of problems such as fatigue and deformation that may occur in 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 elastic member failures.

[0012] Further, when one of the first pressing block and the second pressing block abuts against the moving block, the other is spaced from the moving block.

[0013] With the foregoing technical solution, it is prevented that during the telescopic process of the telescopic rod, the two pressing blocks contact the moving block simultaneously to cause interference, affecting the normal movement of the moving block and the meshing state of the limiting gear, ensuring that only one pressing block acts on the moving block each time, so that the moving block can accurately switch between the locking position and the unlocking position according to the design requirements.

[0014] Further, a chute is provided in the fixed block, and the moving block is adapted to the chute and slidably connected in the chute.

[0015] With the foregoing technical solution, the chute provides a clear movement track for the moving block, so that the moving block can only move along the direction of the chute, thereby ensuring the accuracy and stability of the movement of the moving block. And the chute can position the moving block to achieve accurate control of material discharging and feeding. The adapted connection between the moving block and the chute enhances the connection stability between the fixed block and the moving block.

[0016] Further, the material discharging control mechanism further includes at least one second gear, the second gear is rotatably connected to the stacking rack, the second gear and the limiting gear are arranged at intervals along the telescopic direction of the telescopic rod, and the second gear and the limiting gear are coaxially fixed by a coupling.

[0017] With the foregoing technical solution, the setting of the second gear increases the contact points with the side part of the semi-finished tube blank, making the entire limiting and blanking processes more stable and preventing the semi-finished tube blank from tipping over during movement. When the limiting gear supports the semi-finished tube blank, the second gear can also play an auxiliary supporting role, sharing the force on the limiting gear and preventing the limiting gear from being damaged or deformed due to excessive force, thus improving the stability and reliability of the blanking control mechanism. For example, in the case of a large number of semi-finished tube blanks with a long length, the second gear can work together with the limiting gear to better restrict the movement of the semi-finished tube blank and ensure the accuracy of blanking.

[0018] Furthermore, the number of the blanking control mechanisms is two, and the two blanking control mechanisms are arranged on opposite sides of the feeding device.

[0019] With the foregoing technical solution, the two blanking control mechanisms limit and control the semi-finished tube blank from opposite sides, making the position of the semi-finished tube blank in the stacking rack more stable. Compared with a single blanking control mechanism, the control on both sides can better balance the force on the semi-finished tube blank, preventing the semi-finished tube blank from tilting or shifting due to uneven force and ensuring the stability of the feeding process. For example, when pushing out the semi-finished tube blank, the two blanking control mechanisms on both sides can work synchronously, enabling the semi-finished tube blank to be smoothly pushed out from the bottom of the stacking rack and reducing the possibility of damage to the semi-finished tube blank caused by unilateral force.

[0020] Furthermore, the bottom of the stacking rack is provided with a positioning groove adapted to the semi-tube part and a supporting surface adapted to the side part. The positioning groove extends along the telescopic direction of the first pushing mechanism, and the end of the positioning groove in this direction is open.

[0021] With the foregoing technical solution, when the semi-finished tube blanks in the stacking rack are stacked forward, the semi-tube part is located above the positioning groove and outside the positioning groove, and the supporting surface supports the side part. Therefore, the semi-finished tube blank can be positioned only through the supporting surface. When the semi-finished tube blanks in the stacking rack are stacked backward, the semi-tube part is located in the positioning groove, and the supporting surface supports the side part. At this time, the positioning of the semi-finished tube blank is completed through the positioning groove and the supporting surface. Through the positioning groove and the supporting surface, the semi-finished tube blanks stacked forward or backward can achieve precise vertical positioning at the discharge port, so that when the first pushing mechanism pushes the semi-finished tube blank out of the discharge port subsequently, the semi-finished tube blank will not shake.

[0022] Furthermore, it further includes a second pushing mechanism and a guiding frame. The guiding frame and the first pushing mechanism are located on opposite sides of the discharge port. The first pushing mechanism is used to push the semi-finished tube blank located at the bottom of the stacking rack to the guiding frame, and the second pushing mechanism is arranged at a position corresponding to the guiding frame and is used to push the semi-finished tube blank on the guiding frame to the feeding station. The pushing directions of the first pushing mechanism and the second pushing mechanism are perpendicular.

[0023] With the foregoing technical solution, the provision of the guiding frame provides a stable transition position for the semi-finished tube blank. The semi-finished tube blank can be better supported and positioned on the guiding frame, reducing the possibility of damage to the semi-finished tube blank caused by instability during the pushing process. The vertical pushing method of the first pushing mechanism and the second pushing mechanism makes the force on the semi-finished tube blank more uniform during the transfer process, further enhancing the stability of the loading. For example, when pushing a semi-finished tube blank with a larger size or heavier weight, the guiding frame and the vertical pushing method can effectively prevent the semi-finished tube blank from tilting or falling, ensuring the stable progress of the loading process.

[0024] Furthermore, a notch is provided at a position near the bottom on the side wall of the stacking rack, and the limiting gear is arranged at the notch position and passes through the notch.

[0025] With the foregoing technical solution, the provision of the notch enables the limiting gear to directly contact the semi-finished tube blank in the stacking rack, facilitating the limiting and control of the semi-finished tube blank by the limiting gear. The limiting gear passes through the notch, and can accurately support the side part of the semi-finished tube blank, realizing the precise control of the falling of the semi-finished tube blank.

[0030] The technical solutions of the present application will be described in detail below with specific embodiments. These specific embodiments can be combined or replaced according to the actual situation. For the same or similar concepts or processes, they may not be repeated in some embodiments.

[0031] As shown Figures 8 to 9 in the figure, an R-S line of an electrostatic precipitator includes two semi-tube blank parts 1.1 and several spike teeth 1.2. The semi-tube blank part 1.1 includes a semi-tube part 1.1.1 and side parts 1.1.2 located on opposite sides of the semi-tube part 1.1.1. The two semi-tube blank parts 1.1 are stacked and welded to form a tube blank part 1.3. The tube blank part 1.3 includes a tube blank body 1.3.0, connecting parts 1.3.1 located at both ends of the tube blank body 1.3.0, and tube blank side parts 1.3.2 located on opposite sides of the tube blank body 1.3.0. The tube blank side parts 1.3.2 are formed by enclosing and welding the side parts 1.1.2 of the two semi-tube blank parts 1.1. Several spike teeth 1.2 are arranged at intervals on the tube blank side parts 1.3.2. The spike teeth 1.2 include a fixing part 1.2.1 and a discharging part 1.2.2. The side parts 1.1.2 of the two semi-tube blank parts 1.1 cover the fixing part 1.2.1. The discharging part 1.2.2 is provided with a discharging tip 1.2.3. It also includes a bent part 1.2.4 formed by bending one end of the fixing part 1.2.1 of the spike tooth 1.2 close to the semi-tube part 1.1.1.

[0032] As shown Figures 1 to 7 in the figure, the present application provides an automatic feeding device for an R-S line production line of an electrostatic precipitator, including: A stacking rack 7.1, the bottom of which is provided with a discharging port 7.5. A number of semi-tube blank parts 1.1 are stacked in the stacking rack 7.1. The semi-tube blank part 1.1 includes a semi-tube part 1.1.1 and side parts 1.1.2 located on opposite sides of the semi-tube part 1.1.1. The side parts 1.1.2 of two adjacent semi-tube blank parts 1.1 in the stacking rack 7.1 are arranged at intervals. A first pushing mechanism 7.2, which is arranged at a position corresponding to the discharging port 7.5 and is used to push out the semi-tube blank part 1.1 located at the bottom of the stacking rack 7.1. A blanking control mechanism 8, which includes a limit gear 8.7 and a driving component for controlling the intermittent rotation of the limit gear 8.7. The limit gear 8.7 is rotatably connected to the stacking rack 7.1 and is located on one side of the semi-tube blank part 1.1. The pitch of the teeth of the limit gear 8.7 is adapted to the interval distance between the side parts 1.1.2 of two adjacent semi-tube blank parts 1.1. One tooth of the limit gear 8.7 supports one of the side parts 1.1.2.

[0033] After adopting the above technical solution, the present application has the following advantages: By controlling the intermittent rotation of the limit gear 8.7 through the driving component, the tube blank semi-finished part 1.1 moves downward accordingly. After the lowermost tube blank semi-finished part 1.1 loses the restriction of the limit gear 8.7, it will fall into the discharge port 7.5. At this time, the first pushing mechanism 7.2 pushes the tube blank semi-finished part 1.1 located at the bottom of the stacking rack 7.1 out from the discharge port 7.5, realizing the feeding of the tube blank semi-finished part 1.1. The design of this solution changes the traditional manual feeding mode. Through the automatic feeding device 7, the automatic pushing and conveying of the tube blank semi-finished part 1.1 are realized. There is no need for workers to manually place the semi-finished part on the conveyor belt, greatly reducing the labor input, reducing the labor cost, and at the same time reducing the labor intensity of the workers and avoiding the difficulties and risks that workers may face when handling the relatively large semi-finished parts of the electric dust collector R-S line 1. Since the upper and lower adjacent two side parts 1.1.2 in the stacking rack 7.1 are arranged at intervals, and the tooth pitch of the limit gear 8.7 is adapted thereto, during the process of pushing out the tube blank semi-finished part 1.1, there will be no mutual pressing and friction between the semi-finished parts, effectively avoiding the damage caused by wear of the semi-finished parts, ensuring the quality of the product and the stability of production, and reducing the problems of raw material waste and production efficiency reduction caused by product damage.

[0034] Specifically, the semi-tube parts 1.1.1 of the upper and lower adjacent two tube blank semi-finished parts 1.1 in the stacking rack 7.1 except at the position of the discharge port 7.5 are tightly stacked against each other up and down, and there is a gap between the semi-tube part 1.1.1 of the tube blank semi-finished part 1.1 located at the discharge port 7.5 and the tube blank semi-finished part 1.1 restricted by the limit gear 8.7. The first pushing mechanism 7.2 is a cylinder.

[0035] In one embodiment, such as Figures 3 to 6 and Figure 10As shown in the figure, the driving assembly includes 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 to 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 to the moving block 8.2. The sliding rack 8.4 is slidably 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 slidably connected to the fixed block 8.1 and has a locking position where the fixed rack 8.3 meshes with the limit gear 8.7 and an unlocking position where the sliding rack 8.4 meshes with the limit 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 switches from the first position to the second position, a first abutting block 7.2.2 extending to the front side of the moving block 8.2 is provided at the end of the telescopic rod 7.2.1 of the first pushing mechanism 7.2. When the sliding rack 8.4 moves a pitch distance, when the telescopic rod 7.2.1 of the first pushing mechanism 7.2 retracts, the first abutting block 7.2.2 of the telescopic rod 7.2.1 abuts against and drives the moving block 8.2 to move to the unlocking position.

[0036] Adopting the foregoing technical solution, the specific steps are as follows: When the telescopic rod 7.2.1 of the first pushing mechanism 7.2 retracts after completing the pushing action, as Figures 3 to 4 shown, the first abutting block 7.2.2 of the telescopic rod 7.2.1 will abut against and pull the moving block 8.2 to move to the unlocking position (the limit gear 8.7 and the sliding rack 8.4 are meshed). At this time, the first spring 8.5 will be in a stretched state. Due to the sliding rack 8.4 being pressed by the gravity of the semi-finished pipe blank 1.1 and rotating a tooth pitch, the sliding rack 8.4 moves down a tooth distance and touches 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 Figure 5 and Figure 6 shown). At the same time, the second spring 8.6 is compressed. At this time, the lowermost semi-finished pipe blank 1.1 falls to the discharge port 7.5 after losing the limitation of the limit gear 8.7, completing the blanking action. Subsequently, as Figures 5 to 6 shown, when the first abutting block 7.2.2 moves forward with the telescopic rod 7.2.1 for the pushing action, the restriction of the first abutting block 7.2.2 on the moving block 8.2 gradually disappears, and the first spring 8.5 will gradually pull the moving block 8.2 to move to the locking position (the limit gear 8.7 and the fixed rack 8.3 are meshed). At this time, after the second spring 8.6 extends, it will push the moving rack to the initial first position (as Figure 3 and Figure 4 shown).

[0037] One tooth of the limit gear 8.7 supports the semi-finished tube blank 1.1. Only when the sliding rack 8.4 switches positions and meshes with the limit gear 8.7 to rotate, will a semi-finished tube blank 1.1 be released, effectively avoiding the situation of excessive blanking or inaccurate blanking, and ensuring the accuracy and stability of loading. By using the design that when the telescopic rod 7.2.1 of the first pushing mechanism 7.2 retracts, it abuts against and moves the moving block 8.2 to the unlocking position, automatic triggering of blanking is achieved. Without additional control systems or manual intervention, the entire loading process becomes more automated and smooth, reducing the workload and error probability of manual operations, improving production efficiency, and being more stable when controlling the fall of the semi-finished tube blank 1.1. It can accurately trigger the rotation of the limit gear 8.7 after the telescopic rod 7.2.1 retracts, causing the corresponding semi-finished tube blank 1.1 to fall to the designated position.

[0038] Further, a chute 8.0 is provided in the fixed block 8.1, and the moving block 8.2 is adapted to the chute 8.0 and slidably connected within the chute 8.0.

[0039] With the foregoing technical solution, the chute 8.0 provides a clear movement trajectory for the moving block 8.2, enabling the moving block 8.2 to move only along the direction of the chute 8.0, thereby ensuring the accuracy and stability of the movement of the moving block 8.2. And the chute 8.0 can position the moving block 8.2 to achieve accurate control of blanking and loading. The adapted connection between the moving block 8.2 and the chute 8.0 enhances the connection stability between the fixed block 8.1 and the moving block 8.2.

[0040] Further, the blanking control mechanism 8 further includes at least one second gear. The pitch of the second gear is adapted to the interval distance between two adjacent side portions 1.1.2 up and down. The second gear is rotatably connected to the stacking rack 7.1. The second gear and the limit gear 8.7 are arranged at intervals along the telescopic direction of the telescopic rod 7.2.1. The second gear and the limit gear 8.7 are coaxially fixed by a coupling 8.8.

[0041] Adopting the foregoing technical solution, the setting of the second gear increases the contact points with the side portion 1.1.2 of the semi-finished tube blank 1.1, making the entire limiting and blanking processes more stable and preventing the semi-finished tube blank 1.1 from tipping over during movement. When the limiting gear 8.7 supports the semi-finished tube blank 1.1, the second gear can also play an auxiliary supporting role, sharing the force borne by the limiting gear 8.7 and preventing the limiting gear 8.7 from being damaged or deformed due to excessive force, thereby improving the stability and reliability of the blanking control mechanism 8. For example, in the case where the number of semi-finished tube blanks 1.1 is large and the length is long, the second gear can cooperate with the limiting gear 8.7 to better restrict the movement of the semi-finished tube blank 1.1 and ensure the accuracy of blanking. Specifically, when the limiting gear 8.7 is stationary, the lowermost semi-finished tube blank 1.1 is restricted by both the second gear and the limiting gear 8.7, and when the limiting gear 8.7 rotates, the second gear will rotate simultaneously with the limiting gear 8.7, causing the lowermost semi-finished tube blank 1.1 to fall to the discharge port 7.5 after losing the restriction of the second gear and the limiting gear 8.7.

[0042] Furthermore, the number of the blanking control mechanisms 8 is two, and the two blanking control mechanisms 8 are arranged on the opposite sides of the loading device 7.

[0043] Adopting the foregoing technical solution, the two blanking control mechanisms 8 limit and control the semi-finished tube blank 1.1 from the opposite sides, making the position of the semi-finished tube blank 1.1 in the stacking rack 7.1 more stable. Compared with a single blanking control mechanism 8, the control on both sides can better balance the force received by the semi-finished tube blank 1.1, preventing the semi-finished tube blank 1.1 from tilting or shifting due to uneven force and ensuring the stability of the loading process. For example, when pushing out the semi-finished tube blank 1.1, the two blanking control mechanisms 8 on both sides can work synchronously, enabling the semi-finished tube blank 1.1 to be smoothly pushed out from the bottom of the stacking rack 7.1 and reducing the possibility of damage to the semi-finished tube blank 1.1 caused by unilateral force.

[0044] Furthermore, the bottom of the stacking rack 7.1 is provided with a positioning groove 7.6 adapted to the semi-tube portion 1.1.1 and a supporting surface 7.7 adapted to the side portion 1.1.2. The positioning groove 7.6 extends along the telescopic direction of the first pushing mechanism 7.2, and the end of the positioning groove 7.6 in this direction is open.

[0045] Adopting the foregoing technical solution, when the semi-finished tube blanks 1.1 in the stacking rack 7.1 are stacked forward (as shown in Figure 2 ), the semi-tube portion 1.1.1 is located above the positioning groove 7.6 and outside the positioning groove 7.6, and the supporting surface 7.7 supports the side portion 1.1.2. Therefore, the semi-finished tube blank 1.1 can be positioned only through the supporting surface 7.7; when the semi-finished tube blanks 1.1 in the stacking rack 7.1 are stacked backward (as shown in Figure 1As shown, the semi-tube part 1.1.1 is located in the positioning groove 7.6, and the supporting surface 7.7 supports the side part 1.1.2. At this time, the positioning of the semi-finished tube blank 1.1 is completed through the positioning groove 7.6 and the supporting surface 7.7. Through the positioning groove 7.6 and the supporting surface 7.7, the semi-finished tube blanks 1.1 stacked forward or backward can achieve accurate up-and-down positioning at the discharge port 7.5, so that when the first pushing mechanism 7.2 pushes the semi-finished tube blank 1.1 out of the discharge port 7.5, the semi-finished tube blank 1.1 will not shake.

[0046] Specifically, forward stacking means that the inner wall of the semi-tube part 1.1.1 faces downward, and reverse stacking means that the inner wall of the semi-tube part 1.1.1 faces upward. The end opening is provided so that the telescopic rod 7.2.1 of the first pushing mechanism 7.2 can enter the positioning groove 7.6 and push the semi-finished tube blank 1.1 in the positioning groove 7.6 out.

[0047] Furthermore, as Figure 7 shown, it further includes a second pushing mechanism 7.3 and a guiding frame 7.4. The guiding frame 7.4 and the first pushing mechanism 7.2 are located on opposite sides of the discharge port 7.5. The first pushing mechanism 7.2 is used to push the semi-finished tube blank 1.1 at the bottom of the stacking rack 7.1 to the guiding frame 7.4. The second pushing mechanism 7.3 is arranged at a position corresponding to the guiding frame 7.4 and is used to push the semi-finished tube blank 1.1 on the guiding frame 7.4 to the feeding station. The pushing directions of the first pushing mechanism 7.2 and the second pushing mechanism 7.3 are perpendicular.

[0048] Adopting the foregoing technical solution, the setting of the guiding frame 7.4 provides a stable transition position for the semi-finished tube blank 1.1. The semi-finished tube blank 1.1 can be better supported and positioned on the guiding frame 7.4, reducing the possibility of damage to the semi-finished tube blank 1.1 caused by instability during the pushing process. The perpendicular pushing method of the first pushing mechanism 7.2 and the second pushing mechanism 7.3 makes the semi-finished tube blank 1.1 receive more uniform force during the transfer process, further enhancing the stability of feeding. For example, when pushing a semi-finished tube blank 1.1 with a larger size or heavier weight, the guiding frame 7.4 and the perpendicular pushing method can effectively prevent the semi-finished tube blank 1.1 from tilting or falling, ensuring the stable progress of the feeding process.

[0049] Furthermore, a notch is provided at a position near the bottom on the side wall of the stacking rack 7.1, and the limiting gear 8.7 is arranged at the notch position and passes through the notch.

[0050] With the foregoing technical solution, the notch enables the limiting gear 8.7 to directly contact the semi-finished tube blank 1.1 in the stacking rack 7.1, facilitating the limiting and control of the semi-finished tube blank 1.1 by the limiting gear 8.7. The limiting gear 8.7 passes through the notch and can accurately support the side part 1.1.2 of the semi-finished tube blank 1.1, achieving precise control over the falling of the semi-finished tube blank 1.1.

[0051] In still another embodiment, as Figure 10 and Figure 11 shown, 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 to 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 to the moving block 8.2. The sliding rack 8.4 is slidably 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 slidably connected to the fixed block 8.1 and has a locking position where the fixed rack 8.3 meshes with the limiting gear 8.7 and an unlocking position where the sliding rack 8.4 meshes with the limiting gear 8.7. When the sliding rack 8.4 switches from the first position to the second position, the sliding rack 8.4 moves a pitch distance. The telescopic rod 7.2.1 is provided 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 retracts, the first abutting block 7.2.2 abuts and moves the moving block 8.2 to the unlocking position. When the telescopic rod 7.2.1 of the first pushing mechanism 7.2 extends, the second abutting block 7.2.3 abuts and moves the moving block 8.2 to the locking position. Further, when one of the first abutting block 7.2.2 and the second abutting block 7.2.3 abuts against the moving block 8.2, the other is spaced from the moving block 8.2. Specifically, the positions of the first abutting block 7.2.2 and the second abutting block 7.2.3 are as Figure 10 shown. 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. Wherein the moving distance L1 of the telescopic rod 7.2.1 + the distance L2 between the two abutting surfaces of the moving block 8.2 = the distance L3 between the abutting surface of the first abutting block 7.2.2 and the moving block 8.2 and the abutting surface of the second abutting block 7.2.3 and the moving block 8.2 + the moving distance L4 of the sliding block, and the moving distance L1 of the telescopic rod 7.2.1 is greater than or equal to the length of the semi-finished tube blank 1.1, so that the semi-finished tube blank 1.1 can be fully pushed out.

[0052] With the foregoing technical solution, by providing a first abutting block 7.2.2 and a second abutting block 7.2.3 on the telescopic rod 7.2.1, the telescopic rod 7.2.1 can control the moving block 8.2 both 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 two-way control method makes the position switching of the moving block 8.2 more accurate and stable, can better ensure the meshing state of the limiting gear 8.7, thereby improving the accuracy and stability of feeding. Since there is no need to rely on the elastic force of the elastic member to achieve the position switching of the moving block 8.2, the influence of problems such as fatigue and deformation that may occur in 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 occurrence of inaccurate feeding or equipment failure caused by the failure of the elastic member. To prevent interference from occurring when both abutting blocks come into contact with the moving block 8.2 during the telescopic process of the telescopic rod 7.2.1, affecting the normal movement of the moving block 8.2 and the meshing state of the limiting gear 8.7, ensuring 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. Among them, the vertical portion of the first abutting block 7.2.2 is provided to provide an avoidance effect when the semi-finished tube blank 1.1 drops, so that the telescopic rod 7.2.1 can pull the moving block 8.2 to the unlocking position when retracting without interfering with the dropping of the semi-finished tube blank 1.1.

[0053] It can be understood that there is another embodiment. The difference between this embodiment and the above two embodiments is that the drive assembly is a drive motor with a brake, specifically a stepper motor, which can control the rotation angle of the gear and perform braking at an appropriate time.

[0054] In addition to the above preferred embodiments, there are other implementation manners of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope claimed in the present application.
