Description

Technical Field

[0001] This application relates to an RS line production line for electrostatic precipitators, and in particular to an automatic feeding device for an RS line production line for electrostatic precipitators. Background Technology

[0002] RS wire, as one of the commonly used cathode wires in electrostatic precipitators, has various structural forms, which can be generally divided into two categories: integral welding and split welding. Integral welding is achieved by punching two halves on the same sheet metal, forming and welding them together; this method has a low material utilization rate. Split welding involves fabricating the toothed parts, tube blanks, and connecting pipes separately and then welding them together.

[0003] There are several pressing issues with the current material feeding process on RS production lines. Currently, material feeding on RS production lines primarily relies on manual operation. Specifically, workers need to place the semi-finished blanks onto the conveyor belt. This manual feeding method has significant drawbacks; it not only consumes substantial manpower and time, but also, when handling larger electrostatic precipitator RS lines, the large size and weight of the semi-finished blanks make it difficult for workers to place them smoothly onto the conveyor belt, greatly impacting production efficiency and worker workload. Besides manual feeding, another existing technical solution involves directly stacking the semi-finished blanks and then ejecting them one by one. However, this solution also presents several problems. Because the semi-finished blanks are stacked layer by layer, when the bottom half-finished blank needs to be ejected, it is compressed by the upper half-finished blanks, making ejection difficult. Furthermore, during the ejection process, friction and wear occur between the upper half-finished blanks and the half-finished blanks to be ejected. This not only increases the ejection resistance but also causes unnecessary damage to the ejected half-finished blanks, affecting product quality and production stability. Summary of the Invention

[0004] In order to overcome the shortcomings of slow feeding of tube blanks and semi-blanks in the prior art, this application provides an automatic feeding device for the RS line production line of electrostatic precipitators, which can realize rapid feeding of tube blanks and semi-blanks.

[0005] To achieve the above objectives, this application adopts the following technical solution: an automatic feeding device for an RS line production line of an electrostatic precipitator, comprising:

[0006] The stacking rack has a discharge port at the bottom. Several tube blank half blanks are stacked inside the stacking rack. Each tube blank half blank includes a half tube part and side parts located on opposite sides of the half tube part. Two adjacent side parts are spaced apart inside the stacking rack.

[0007] The first ejection mechanism, located at the position corresponding to the discharge port, is used to eject the tube blank half-blank located at the bottom of the stacking rack;

[0008] The feeding control mechanism includes a limiting gear and a drive assembly for controlling the intermittent rotation of the limiting gear. The limiting gear is rotatably connected to the stacking rack and located on one side of the tube blank half-blank. The tooth pitch of the limiting gear is adapted to the interval distance between two adjacent upper and lower side parts. One tooth of the limiting gear supports one of the side parts.

[0009] By adopting the above technical solution, this application has the following advantages: The intermittent rotation of the limiting gear, controlled by the drive assembly, causes the tube blank half-bulk to move downwards. The lowest tube blank half-bulk, after losing the restraint of the limiting gear, falls into the discharge port. At this time, the first ejection mechanism pushes the tube blank half-bulk located at the bottom of the stacking rack out of the discharge port, thus realizing the loading of the tube blank half-bulk. This design changes the traditional manual loading mode, achieving automatic ejection and conveying of the tube blank half-bulk through an automatic loading device. It eliminates the need for workers to manually place the half-bulk onto the conveyor belt, greatly reducing manpower input and labor costs. It also reduces the labor intensity of workers and avoids the difficulties and risks that workers may face when handling large electrostatic precipitator RS line half-bulks. Because the upper and lower adjacent sides of the stacking rack are spaced apart and the pitch of the limiting gear is matched with it, the semi-blanks will not press or rub against each other during the process of pushing out the tube blank semi-blanks. This effectively avoids damage to the semi-blanks caused by wear, ensures product quality and production stability, and solves the problems of raw material waste and reduced production efficiency caused by product damage.

[0010] Furthermore, the drive assembly 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 located 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 for engaging the fixed rack with a limit gear and an unlocking position for engaging the sliding rack with the limit gear. The first spring is located between the fixed block and the moving block to keep the moving block in the locked 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 of one tooth pitch. When the telescopic rod of the first push-out mechanism retracts, the first abutting block of the telescopic rod abuts and drives the moving block to the unlocking position.

[0011] Using the aforementioned technical solution, the specific steps are as follows: When the telescopic rod of the first ejection mechanism retracts after completing the pushing action, it will press against and pull the moving block to the unlocked position (the limit gear and the sliding rack are engaged). At this time, the first spring will be in a stretched state. Due to the pressure of the weight of the tube blank half-bulk, the sliding rack rotates one tooth's stroke, causing the sliding rack to move down one tooth's distance and touch the bottom wall of the sliding groove where the sliding rack is located, which is the second position of the sliding rack. At the same time, the second spring is compressed. At this time, the lowest tube blank half-bulk, after losing the limit of the limit gear, falls to the discharge port, completing the unloading action. Subsequently, the first spring will pull the moving block to the locked position (the limit gear and the fixed rack are engaged). At this time, the second spring extends and pushes the moving rack back to the initial first position.

[0012] One tooth of the limiting gear supports a half-bulb. Only when the sliding rack switches positions and meshes with the limiting gear will a half-bulb be released, effectively preventing over-feeding or inaccurate feeding and ensuring the accuracy and stability of the feeding process. The automatic triggering of feeding is achieved by utilizing the design of the telescopic rod of the first ejection mechanism retracting to press against and move the moving block to the unlocked position. No additional control system or manual intervention is required, making the entire feeding process more automated and smooth, reducing the workload and error probability of manual operation, improving production efficiency, and providing greater stability when controlling the falling of the half-bulb. It accurately triggers the rotation of the limiting gear after the telescopic rod retracts, causing the corresponding half-bulb to fall to the designated position.

[0013] Furthermore, the drive 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 located 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 for engaging the fixed rack with a limit gear and an unlocking position for engaging the sliding rack with the limit gear. When the sliding rack switches from the first position to the second position, the sliding rack moves a distance of one tooth pitch. 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 located between the first abutting block and the second abutting block. When the telescopic rod of the first push-out mechanism retracts, the first abutting block abuts and moves the moving block to the unlocking position. When the telescopic rod of the first push-out mechanism extends, the second abutting block abuts and moves the moving block to the locking position.

[0014] By employing the aforementioned technical solution, a first and a second clamping block are installed on the telescopic rod, allowing control of the moving block during both retraction and extension. When the telescopic rod retracts, the first clamping block moves the moving block to the unlocked position; when the telescopic rod extends, the second clamping block moves the moving block to the locked position. This bidirectional control method makes the position switching of the moving block more accurate and stable, better ensuring the meshing state of the limit gears, thereby improving the accuracy and stability of feeding. Since the position switching of the moving block does not rely on the elastic force of the elastic element, the potential fatigue or deformation of the elastic element is avoided, thus enhancing the stability and reliability of the entire automatic feeding device and reducing the occurrence of inaccurate feeding or equipment failure due to elastic element malfunction.

[0015] Furthermore, when one of the first and second abutting blocks is pressed against the moving block, the other is spaced apart from the moving block.

[0016] By adopting the aforementioned technical solution, interference is prevented from occurring when both abutting blocks simultaneously contact the moving block during the extension and retraction of the telescopic rod, which would affect the normal movement of the moving block and the meshing state of the limit gear. This ensures that only one abutting block acts on the moving block at any given time, enabling the moving block to switch accurately between the locked and unlocked positions as required by the design.

[0017] Furthermore, the fixed block is provided with a sliding groove, and the moving block is adapted to and slidably connected to the sliding groove.

[0018] Using the aforementioned technical solution, the chute provides a clear movement trajectory for the moving block, ensuring that the moving block can only move along the direction of the chute, thereby guaranteeing the accuracy and stability of the moving block's movement. Furthermore, the chute can position the moving block, enabling accurate control of material feeding and unloading. The adaptive connection between the moving block and the chute enhances the connection stability between the fixed block and the moving block.

[0019] Furthermore, the feeding control mechanism also includes at least one second gear, which is rotatably connected to the stacking frame. 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 by a coupling.

[0020] By adopting the aforementioned technical solution, the addition of the second gear increases the contact points with the side of the tube blank semi-form piece, making the entire limiting and blanking process more stable and preventing the tube blank semi-form piece from tipping over during movement. When the limiting gear supports the tube blank semi-form piece, the second gear also plays an auxiliary supporting role, sharing the force of the limiting gear and preventing damage or deformation of the limiting gear due to excessive force, thereby improving the stability and reliability of the blanking control mechanism. For example, when there are many tube blank semi-form pieces and their length is long, the second gear can work together with the limiting gear to better restrict the movement of the tube blank semi-form piece and ensure the accuracy of blanking.

[0021] Furthermore, there are two feeding control mechanisms, which are located on opposite sides of the feeding device.

[0022] Using the aforementioned technical solution, two feeding control mechanisms limit and control the semi-finished tube blank from opposite sides, making its position within the stacking rack more stable. Compared to a single feeding control mechanism, dual-sided control better balances the forces acting on the semi-finished tube blank, preventing it from tilting or shifting due to uneven force and ensuring the stability of the feeding process. For example, when ejecting the semi-finished tube blank, the feeding control mechanisms on both sides can work synchronously, allowing the semi-finished tube blank to be smoothly ejected from the bottom of the stacking rack, reducing the possibility of damage to the semi-finished tube blank due to unilateral force.

[0023] Furthermore, the bottom of the stacking rack is provided with a positioning groove adapted to the half-tube portion and a support surface adapted to the side portion. The positioning groove extends along the extension and retraction direction of the first ejection mechanism, and the end of the positioning groove in this direction is open.

[0024] Using the aforementioned technical solution, when the tube blank half-bulks in the stacking rack are stacked in the forward direction, the half-tube portion is located above and outside the positioning groove, and the supporting surface supports the side portion. Therefore, the tube blank half-bulk can be positioned using only the supporting surface. When the tube blank half-bulks in the stacking rack are stacked in the reverse direction, the half-tube portion is located inside the positioning groove, and the supporting surface supports the side portion. In this case, the positioning of the tube blank half-bulk is completed by the positioning groove and the supporting surface. Through the positioning groove and the supporting surface, the tube blank half-bulks stacked in the forward or reverse direction can achieve precise vertical positioning at the discharge port, so that the tube blank half-bulk will not wobble when the first ejection mechanism pushes the tube blank half-bulk out of the discharge port.

[0025] Furthermore, it also includes a second ejection mechanism and a guide frame. The guide frame and the first ejection mechanism are located on opposite sides of the discharge port. The first ejection mechanism is used to eject the tube blank half-blank located at the bottom of the stacking rack to the guide frame. The second ejection mechanism is located at a position corresponding to the guide frame and is used to eject the tube blank half-blank on the guide frame to the loading station. The pushing directions of the first ejection mechanism and the second ejection mechanism are perpendicular.

[0026] By employing the aforementioned technical solution, the guide frame provides a stable transition position for the tube billet semi-finished piece. The semi-finished piece receives better support and positioning on the guide frame, reducing the possibility of damage due to instability during the feeding process. The vertical feeding method of the first and second ejection mechanisms ensures more even force distribution on the semi-finished piece during transfer, further enhancing the stability of the feeding process. For example, when feeding larger or heavier semi-finished pieces, the guide frame and vertical feeding method effectively prevent the semi-finished piece from tilting or falling, ensuring the stable progress of the feeding process.

[0027] Furthermore, a notch is provided on the side wall of the stacking rack near the bottom, and the limiting gear is located at the notch and passes through the notch.

[0028] Using the aforementioned technical solution, the notch design allows the limiting gear to directly contact the tube blank half-bulk within the stacking rack, facilitating the limiting gear's positioning and control of the tube blank half-bulk. The limiting gear, passing through the notch, can accurately support the side of the tube blank half-bulk, achieving precise control over its descent. Attached Figure Description

[0044] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0045] like Figures 8 to 9 As shown, an RS line for an electrostatic precipitator includes two tube blank half-blades 1.1 and several teeth 1.2. The tube blank half-blade 1.1 includes a half-tube portion 1.1.1 and side portions 1.1.2 located on opposite sides of the half-tube portion 1.1.1. The two tube blank half-blades 1.1 are stacked and welded to form a tube blank 1.3. The tube blank 1.3 includes a tube blank body 1.3.0, connecting portions 1.3.1 located at both ends of the tube blank body 1.3.0, and tube blank side portions 1.3.2 located on opposite sides of the tube blank body 1.3.0. The tube blank side portions 1.3... 2 is formed by joining and welding the side portions 1.1.2 of two tube blank half-blanks 1.1 together. Several serrations 1.2 are spaced apart on the side portion 1.3.2 of the tube blank. Each serration 1.2 includes a fixing portion 1.2.1 and a discharge portion 1.2.2. The side portions 1.1.2 of the two tube blank half-blanks 1.1 cover the fixing portion 1.2.1. The discharge portion 1.2.2 is provided with a discharge tip 1.2.3. It also includes a bent portion 1.2.4 formed by bending the fixing portion 1.2.1 of the serration 1.2 near the end of the half-tube portion 1.1.1.

[0046] like Figures 1 to 7 As shown, this application provides an automatic feeding device for an RS line production line of an electrostatic precipitator, comprising:

[0047] The stacking rack 7.1 has a discharge port 7.5 at its bottom. Several tube blank half blanks 1.1 are stacked inside the stacking rack 7.1. Each tube blank half blank 1.1 includes a half tube part 1.1.1 and side parts 1.1.2 located on opposite sides of the half tube part 1.1.1. The stacking rack 7.1 has two adjacent side parts 1.1.2 spaced apart.

[0048] The first ejection mechanism 7.2 is located at a position corresponding to the discharge port 7.5 and is used to eject the tube blank half blank 1.1 located at the bottom of the stack rack 7.1;

[0049] The feeding control mechanism 8 includes a limiting gear 8.7 and a drive assembly for controlling the intermittent rotation of the limiting gear 8.7. The limiting gear 8.7 is rotatably connected to the stacking rack 7.1 and located on one side of the tube blank half blank 1.1. The tooth pitch of the limiting gear 8.7 is adapted to the interval distance between two adjacent side parts 1.1.2. One tooth of the limiting gear 8.7 supports one side part 1.1.2.

[0050] After adopting the above technical solution, this application has the following advantages: By controlling the intermittent rotation of the limiting gear 8.7 through the drive component, the tube blank half-bulk 1.1 moves downward accordingly. After the bottom tube blank half-bulk 1.1 is no longer restricted by the limiting gear 8.7, it will fall into the discharge port 7.5. At this time, the first ejection mechanism 7.2 pushes the tube blank half-bulk 1.1 located at the bottom of the stacking rack 7.1 out of the discharge port 7.5, realizing the feeding of the tube blank half-bulk 1.1. The design of this solution changes the traditional manual feeding mode. The automatic feeding device 7 realizes the automatic ejection and conveying of the tube blank half-bulk 1.1, eliminating the need for workers to manually place the half-bulk onto the conveyor belt, greatly reducing manpower input, lowering labor costs, and also reducing the labor intensity of workers, avoiding the difficulties and risks that workers may face when handling large electrostatic precipitator RS line 1 half-bulks. Because the stacking rack 7.1 has two adjacent side sections 1.1.2 spaced apart, and the pitch of the limiting gear 8.7 is matched with it, the semi-bills will not press or rub against each other during the process of pushing out the tube blank semi-bills 1.1. This effectively avoids damage to the semi-bills caused by wear, ensures product quality and production stability, and reduces the waste of raw materials and reduced production efficiency caused by product damage.

[0051] Specifically, the upper and lower adjacent tube blank half blanks 1.1 and the lower tube portions 1.1.1 of the stacking rack 7.1, except for the discharge port 7.5, are stacked tightly together. There is a gap between the tube blank half blank 1.1 located at the discharge port 7.5 and the tube blank half blank 1.1 and the lower tube portion 1.1.1 restricted by the limiting gear 8.7. The first ejection mechanism 7.2 is a cylinder.

[0052] In one embodiment, such as Figures 3 to 6 as well as Figure 10 As shown, the drive 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 stacker 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 located 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 first position and a second position. 8.3 has a locking position where it engages with the limiting gear 8.7 and an unlocking position where it engages with the limiting gear 8.7. A first spring 8.5 is located between the fixed block 8.1 and the moving block 8.2 to keep the moving block 8.2 in the locked position. When the sliding rack 8.4 switches 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. When the sliding rack 8.4 moves a distance of one tooth pitch, and the telescopic rod 7.2.1 of the first push-out mechanism 7.2 retracts, 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.

[0053] The specific steps of adopting the aforementioned technical solution are as follows: When the telescopic rod 7.2.1 of the first ejection mechanism 7.2 retracts after completing the ejection action, as follows: Figures 3 to 4 As shown, the first clamping block 7.2.2 of the telescopic rod 7.2.1 will clamp and pull the moving block 8.2 to the unlocked 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. Due to the pressure of the weight of the tube blank half-blank 1.1, the sliding rack 8.4 rotates one tooth's stroke, causing the sliding rack 8.4 to move downwards by one tooth's distance and touch the bottom wall of the sliding groove where the sliding rack 8.4 is located, which is the second position of the sliding rack 8.4 (as shown). Figure 5 and Figure 6 As shown in the diagram, simultaneously, the second spring 8.6 is compressed. At this point, the bottommost tube blank half-bulk 1.1, after losing the limit of the limiting gear 8.7, falls to the discharge port 7.5, completing the unloading action. Then, as... Figures 5 to 6 As shown, when the first abutting block 7.2.2 pushes forward with the telescopic rod 7.2.1, the restriction of the first abutting block 7.2.2 on the moving block 8.2 gradually disappears. The first spring 8.5 will gradually pull the moving block 8.2 to the locked position (the limiting gear 8.7 and the fixed rack 8.3 are engaged). At this time, the second spring 8.6 extends and pushes the moving rack to the initial first position (as shown). Figure 3 and Figure 4 (As shown).

[0054] One tooth of the limiting gear 8.7 supports the tube blank half-piece 1.1. Only when the sliding rack 8.4 switches positions and meshes with the limiting gear 8.7 will one tube blank half-piece 1.1 be released, effectively avoiding over-feeding or inaccurate feeding, and ensuring the accuracy and stability of feeding. The automatic triggering of feeding is achieved by utilizing the design of the telescopic rod 7.2.1 of the first ejection mechanism 7.2 retracting to press against and move the moving block 8.2 to the unlocked position. No additional control system or manual intervention is required, making the entire feeding process more automated and smooth, reducing the workload and error probability of manual operation, improving production efficiency, and providing greater stability when controlling the drop of the tube blank half-piece 1.1. It can accurately trigger the rotation of the limiting gear 8.7 after the telescopic rod 7.2.1 retracts, causing the corresponding tube blank half-piece 1.1 to drop to the designated position.

[0055] Furthermore, 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 to the sliding groove 8.0.

[0056] Using the aforementioned technical solution, the slide 8.0 provides a clear movement trajectory for the moving block 8.2, ensuring that the moving block 8.2 can only move along the direction of the slide 8.0, thus guaranteeing the accuracy and stability of the moving block 8.2's movement. Furthermore, the slide 8.0 can position the moving block 8.2, achieving accurate control of material feeding and unloading. The adaptive connection between the moving block 8.2 and the slide 8.0 enhances the connection stability between the fixed block 8.1 and the moving block 8.2.

[0057] Furthermore, the feeding control mechanism 8 also includes at least one second gear. The pitch of the second gear is adapted to the interval distance between the two adjacent upper and lower side portions 1.1.2. The second gear is rotatably connected to the stacking rack 7.1. The second gear and the limiting gear 8.7 are spaced apart along the extension and retraction direction of the telescopic rod 7.2.1. The second gear and the limiting gear 8.7 are coaxially fixed by the coupling 8.8.

[0058] By adopting the aforementioned technical solution, the second gear increases the contact point with the side 1.1.2 of the tube blank half-piece 1.1, making the entire limiting and unloading process more stable and preventing the tube blank half-piece 1.1 from tipping over during movement. When the limiting gear 8.7 supports the tube blank half-piece 1.1, the second gear can also play an auxiliary supporting role, sharing the force of 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 unloading control mechanism 8. For example, when there are many tube blank half-pieces 1.1 and they are long, the second gear can work together with the limiting gear 8.7 to better restrict the movement of the tube blank half-pieces 1.1 and ensure the accuracy of the material cutting. Specifically, when the limiting gear 8.7 is stationary, the bottom tube blank half-piece 1.1 is restricted by the second gear and the limiting gear 8.7. When the limiting gear 8.7 rotates, the second gear will rotate at the same time as the limiting gear 8.7, so that the bottom tube blank half-piece 1.1 will fall to the discharge port 7.5 after it is no longer restricted by the second gear and the limiting gear 8.7.

[0059] Furthermore, there are two feeding control mechanisms 8, which are located on opposite sides of the feeding device 7.

[0060] Using the aforementioned technical solution, two feeding control mechanisms 8 limit and control the tube blank half-bill 1.1 from opposite sides, making the position of the tube blank half-bill 1.1 more stable within the stacking rack 7.1. Compared to a single feeding control mechanism 8, the control from both sides can better balance the forces on the tube blank half-bill 1.1, preventing it from tilting or shifting due to uneven force, thus ensuring the stability of the feeding process. For example, when ejecting the tube blank half-bill 1.1, the feeding control mechanisms 8 on both sides can work synchronously, allowing the tube blank half-bill 1.1 to be smoothly ejected from the bottom of the stacking rack 7.1, reducing the possibility of damage to the tube blank half-bill 1.1 due to unilateral force.

[0061] Furthermore, the bottom of the stacking rack 7.1 is provided with a positioning groove 7.6 adapted to the half-pipe portion 1.1.1 and a support surface 7.7 adapted to the side portion 1.1.2. The positioning groove 7.6 extends along the extension and retraction direction of the first push-out mechanism 7.2, and the end of the positioning groove 7.6 in this direction is open.

[0062] Using the aforementioned technical solution, when the tube blank half-blanks 1.1 are stacked in the stacking rack 7.1 in a forward orientation (e.g.) Figure 2 As shown), the half-tube portion 1.1.1 is located above and outside the positioning groove 7.6, and the support surface 7.7 supports the side portion 1.1.2. Therefore, the tube blank half-bulk 1.1 can be positioned solely by the support surface 7.7. When the tube blank half-bulks 1.1 in the stacking rack 7.1 are stacked in reverse (e.g. 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] Using the aforementioned technical solution, the notch design allows the limiting gear 8.7 to directly contact the tube blank half-bulk 1.1 within the stacking rack 7.1, facilitating the limiting gear 8.7's positioning and control of the tube blank half-bulk 1.1. The limiting gear 8.7, passing through the notch, can accurately support the side portion 1.1.2 of the tube blank half-bulk 1.1, achieving precise control over the descent of the tube blank half-bulk 1.1.

[0068] In another embodiment, such as Figure 10 and Figure 11 As shown, the drive 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 stacker 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 located 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 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. When the sliding rack 8.4 switches from the first position to the second position, the sliding rack... 8.4 Moving a distance of one tooth pitch, the telescopic rod 7.2.1 is provided with a first abutting block 7.2.2 and a second abutting block 7.2.3 spaced apart along the telescopic direction. One side of the moving block 8.2 is located 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 push-out mechanism 7.2 retracts, 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 push-out mechanism 7.2 extends, the second abutting block 7.2.3 abuts and moves the moving block 8.2 to the locked position. Furthermore, when one of the first abutting block 7.2.2 and the second abutting block 7.2.3 abuts the moving block 8.2, the other is spaced apart 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 follows: Figure 10 As shown, the first abutting block 7.2.2 is located at the end of the telescopic rod 7.2.1, and the second abutting block 7.2.3 is located on the rear side. 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 surfaces of the first abutting block 7.2.2 and the moving block 8.2 and the second abutting block 7.2.3 and the moving block 8.2 + the moving distance L4 of the sliding block. The moving distance L1 of the telescopic rod 7.2.1 is greater than or equal to the length of the tube blank half-bill 1.1, so that the tube blank half-bill 1.1 can be fully pushed out.

[0069] By employing the aforementioned technical solution, a first abutting block 7.2.2 and a second abutting block 7.2.3 are provided on the telescopic rod 7.2.1, enabling the telescopic rod 7.2.1 to control the moving block 8.2 during both retraction and extension. When the telescopic rod 7.2.1 retracts, the first abutting block 7.2.2 moves the moving block 8.2 to the unlocked position; when the telescopic rod 7.2.1 extends, the second abutting block 7.2.3 moves the moving block 8.2 to the locked position. This bidirectional control method makes the position switching of the moving block 8.2 more accurate and stable, better ensuring the meshing state of the limit gear 8.7, thereby improving the accuracy and stability of feeding. Since the position switching of the moving block 8.2 does not rely on the elastic force of the elastic element, the impact of fatigue, deformation, and other problems that may occur with the elastic element on the system performance is avoided, thus enhancing the stability and reliability of the entire automatic feeding device 7 and reducing the occurrence of inaccurate feeding or equipment failure due to elastic element failure. To prevent interference caused by both abutting blocks simultaneously contacting the moving block 8.2 during the extension and retraction of the telescopic rod 7.2.1, thus affecting the normal movement of the moving block 8.2 and the meshing state of the limiting gear 8.7, and to ensure that only one abutting block acts on the moving block 8.2 at a time, so that the moving block 8.2 can accurately switch between the locked and unlocked positions as designed, the vertical part of the first abutting block 7.2.2 is designed to avoid the falling of the tube blank half-bulk 1.1, so that when the telescopic rod 7.2.1 retracts, it can pull the moving block 8.2 to the unlocked position without interfering with the falling of the tube blank half-bulk 1.1.

All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection claimed in this application.
