Description

Technical Field

[0001] This application relates to the field of washing machine manufacturing equipment, and in particular to a fully automatic rolling machine. Background Technology

[0002] A rolling machine is a metal processing device mainly used to roll flat metal into circular or cylindrical shapes. It is widely used in the manufacture of circular or cylindrical metal pipes, containers, cylinders, and other products. In the production of washing machine inner drums, the stainless steel drum body is made by rolling pre-cut rectangular stainless steel sheets into a curved, near-cylindrical shape using a rolling machine.

[0003] In existing production lines, workers need to manually feed rectangular stainless steel sheets into a rolling machine. After the sheets are rolled, workers manually remove them from the rolling machine and transfer them to the next processing stage. Because the thinner stainless steel sheets are quite sharp, workers are prone to cuts when manually moving the sheets and transferring the cylinders. This makes it necessary for workers to operate slowly and carefully, resulting in low production efficiency of stainless steel inner drums for washing machines. Utility Model Content

[0004] In order to improve the production efficiency and safety of rolling stainless steel drum bodies for washing machines, this application provides a fully automatic rolling machine.

[0005] The fully automatic rolling machine provided in this application adopts the following technical solution: A fully automatic rolling machine includes: A rolling mechanism includes a frame, a rolling roller assembly, and a drive device. The rolling roller assembly is mounted on the frame, and the drive device is located on one side of the frame. The output end of the drive device is connected to one end of the rolling roller assembly to drive the rolling roller assembly to rotate. The feeding mechanism includes a feeding conveyor and a moving device; The feeding conveyor is located on the feeding side of the rolling mechanism, and the end of the feeding conveyor corresponds to the feeding end of the rolling mechanism. A limiting component is mounted on the feeding conveyor, and the limiting component forms a limiting channel that aligns with the inlet of the rolling roller group. The mobile device includes a suspension frame, a mobile frame, and an adsorption assembly. The suspension frame is disposed above the feeding conveying device, and the mobile frame is movably connected to the suspension frame. The mobile frame can be translated horizontally along the width direction of the feeding conveying device or moved vertically up and down. At least two adsorption assemblies are provided. One end of the adsorption assembly is fixed to the mobile frame and the other end faces the feeding conveying device. The other end of the adsorption assembly is an adsorption surface.

[0006] During the production of stainless steel tub body for washing machine inner drum, a stack of cut stainless steel sheets is placed on one end of the feeding conveyor and then moved to the bottom of the moving device. The moving frame of the moving device descends, causing the adsorption component to contact and adhere the uppermost stainless steel sheet. Then the moving frame rises to lift the uppermost stainless steel sheet. The moving frame moves above the limiting channel formed by the limiting component, and then the moving frame descends to place the stainless steel sheet into the limiting channel for conveying. Since the limiting channel corresponds to the inlet of the rolling roller group, the stainless steel sheet in the limiting channel is conveyed to the rolling roller group for rolling and pressing by the conveying device.

[0007] By adopting the above scheme, the operations of loading and transferring stainless steel sheets, which originally relied on manual labor, are designed to be automated and collaborative between the loading mechanism and the rolling mechanism. The loading and conveying device is responsible for transporting the sheets to the designated position, while the moving device accurately grasps and places the sheets, thereby replacing manual operation, avoiding direct contact between workers and sharp sheets, and reducing the risk of injury. At the same time, automated continuous operation reduces the time lost from manual operation and improves production efficiency. The rolling mechanism consists of a frame, a rolling roller assembly, and a drive device. The drive device drives the rolling roller assembly to rotate, providing the power required for rolling and realizing the core function of rolling stainless steel sheets into a cylindrical shape. Located on the feeding side of the rolling mechanism, the moving device automatically transports a stack of cut stainless steel sheets to the area below the moving device, realizing the initial transfer of the sheets and reducing manual handling steps. The limiting components mounted on it form a limiting channel, which guides and positions the sheets, ensuring that the sheets can accurately enter the rolling roller assembly and guaranteeing rolling accuracy and stability. The coordinated design of the suspension frame, moving frame, and adsorption assembly provides the installation foundation. The moving frame can move horizontally along the width and vertically up and down on the suspension frame, enabling flexible movement in three-dimensional space. The adsorption assembly uses its adsorption surface to firmly grasp the sheet metal, accurately gripping and placing it. It lifts the top sheet metal from the conveying device and places it into the limiting channel, completing the transfer of the sheet metal from the conveying device to the feeding end of the rolling mechanism, replacing manual handling and feeding operations. The automated feeding process eliminates the need for manual feeding of sheet metal into the rolling machine one by one. Furthermore, after each sheet is rolled, the next sheet metal can be fed immediately, reducing the time interval between manual operations and enabling continuous production. Compared to traditional manual feeding and transfer methods, this significantly improves the rolling efficiency of the stainless steel drum of the washing machine. Through the automated operation of the feeding mechanism, workers do not need to directly contact the sharp edges of the stainless steel sheet metal, avoiding the risk of cuts during manual sheet metal movement and drum transfer, effectively ensuring worker safety.

[0008] Preferably, the adsorption components are arranged in two columns, with at least two in each column. The two columns of adsorption components correspond to the long side of the stainless steel plate, and the adsorption components in each column are evenly spaced.

[0009] By adopting the above scheme, two rows of adsorption components are set up, with at least two in each row and evenly spaced, corresponding to the long side of the board, achieving multi-point, symmetrical adsorption of the board. Multi-point adsorption disperses the adsorption force, avoiding excessive local stress on the board and deformation; the symmetrical layout ensures that the board is subjected to balanced forces during adsorption and transfer, preventing the board from tilting or slipping, thereby improving adsorption reliability and board transfer stability, reducing production interruptions and quality defects caused by adsorption problems, and improving overall production efficiency and safety.

[0010] Preferably, the adsorption assembly includes a connecting rod and a vacuum suction cup. One end of the connecting rod is fixed to the movable frame, and the other end of the connecting rod faces the feeding and conveying device. The vacuum suction cup is fixed to the other end of the connecting rod, and its adsorption surface is parallel to the surface of the feeding and conveying device.

[0011] By adopting the above solution, one end of the connecting rod is fixed to the moving frame, and the other end is equipped with a vacuum suction cup. This allows the position of the vacuum suction cup to be flexibly adjusted according to actual production needs, precisely controlling the suction position and ensuring accurate suction of the top layer of stainless steel sheet each time. It also ensures that the suction surface of the vacuum suction cup is parallel to the surface of the feeding conveyor, allowing the vacuum suction cup to evenly suction the sheet and preventing deformation due to uneven force. This guarantees the integrity of the stainless steel sheet and the accuracy of subsequent rolling processing. Furthermore, the simple and compact structural design facilitates installation, maintenance, and component replacement, reducing equipment maintenance costs and difficulty. During production, workers do not need to frequently adjust the suction components, further reducing manual intervention.

[0012] Preferably, the rolling roller assembly includes a positioning roller and a pressing roller. The positioning roller is located on the frame near the front side of the feeding conveyor. The positioning roller includes a pair of roller shafts arranged parallel to each other. The roller clamping gap of the positioning roller is flush with the surface of the feeding conveyor. The pressing roller is located behind the positioning roller. The entry roller clamping gap of the pressing roller is aligned with the roller clamping gap of the positioning roller.

[0013] By adopting the above scheme, a pair of parallel rollers are set up to form a roller clamping gap, flush with the surface of the feeding conveyor. This allows for precise horizontal positioning of the stainless steel sheet conveyed from the limiting channel, ensuring the sheet is in the correct position before entering the rolling process. A rolling roller is placed after the positioning roller, with its entry roller clamping gap aligned with that of the positioning roller, ensuring a smooth transition of the sheet from the positioning roller to the rolling roller. The rolling roller applies pressure to the positioned sheet to roll it into a circle. Through precise roller clamping gap design and coordination with the positioning roller, stainless steel sheets of different thicknesses and sizes can be stably rolled, achieving high-quality rolling processing. The precise positioning of the positioning roller and the precise rolling of the rolling roller ensure that the stainless steel sheet is rolled according to the preset shape and size, effectively controlling parameters such as the diameter error and roundness error of the rolled cylinder, improving product quality, reducing scrap rate, and lowering production costs. The coordinated operation of the positioning roller and the rolling roller reduces the need for repeated adjustments and rework due to positional deviations during the rolling process, enabling the rolling process to be carried out quickly and continuously without frequent manual intervention in the position of the sheet metal. This significantly shortens the production cycle of a single stainless steel inner drum for washing machines and improves overall production efficiency.

[0014] Preferably, the rolling pressure roller is a three-axis symmetrical pressure roller. The upper roller of the rolling pressure roller includes a shaft core and two bushings. The shaft core is rotatably mounted on the frame and connected to the drive device. The two bushings are fitted onto the shaft core with an adjustable spacing. The two bushings cooperate with the two lower rollers of the rolling pressure roller to roll the long side of the stainless steel sheet.

[0015] By adopting the above scheme, the upper roller of the pressure roller is configured with two bushings fitted onto a shaft core. The shaft core drives the bushings to rotate, and the bushings, together with the two lower rollers, press the edges of the stainless steel sheet to form a cylindrical shape. Pressing with the two bushings allows only the edges of the stainless steel sheet to be pressed, without affecting the shape of the center. This enables the pressure roller to press stainless steel sheets with punched and shaped centers. By adjusting the bushing spacing, the pressure roller can be adapted to various specifications of stainless steel sheets, eliminating the need to change the pressing equipment or perform complex equipment adjustments for sheets of different widths. This reduces equipment costs and production preparation time, and improves equipment versatility and production flexibility. Furthermore, when dealing with stainless steel sheets of different widths, the bushing spacing can be adjusted to precisely match the sheet width, ensuring that the pressing area formed by the bushings and the lower rollers completely covers the long side of the sheet. This ensures that all parts of the sheet receive uniform and appropriate pressure, avoiding rounding defects caused by mismatched pressing areas.

[0016] Preferably, the system further includes an unloading mechanism, which includes a limiting baffle. The limiting baffle is vertically mounted on the frame and is located above the rolling mechanism. The surface of the limiting baffle faces the front and rear sides of the rolling mechanism, and its bottom edge is adjacent to the outlet of the rolling roller assembly.

[0017] By adopting the above solution, a vertically supported limiting baffle is set above the rolling mechanism. During the rolling process of the stainless steel drum of the washing machine, due to the elasticity of the sheet material itself and the rolling stress, the stainless steel arc-shaped sheet exiting from the rolling roller assembly will warp upwards. When gradually rolled into a cylindrical shape, it is very easy for it to buckle back into the rolling roller assembly. By setting a vertical limiting baffle above the rolling mechanism, the limiting baffle forms a physical block on the upwardly warped stainless steel arc-shaped sheet, changing the movement trajectory of the sheet material and preventing it from buckling back into the rolling roller assembly. The limiting baffle effectively avoids the situation of the stainless steel sheet buckling back into the rolling roller assembly, allowing the sheet material to be smoothly rolled into a cylinder and directly unloaded on the exit side of the rolling roller assembly. There is no need for manual intervention to deal with problems such as jamming caused by buckling, which greatly shortens the unloading time, improves the unloading efficiency, and thus improves the overall production efficiency of the fully automatic rolling machine.

[0018] Preferably, the limiting baffle includes a continuous arc-shaped portion and a vertical portion, the arc-shaped portion being located near the exit of the rolling roller assembly, and the vertical portion being located above the arc-shaped portion.

[0019] By adopting the above solution, during the unloading process of stainless steel sheet rolls, the curved plate exiting the roll assembly warps upwards due to elasticity and stress. By designing the limiting baffle as a continuous curved section and a vertical section, the smooth curve of the curved section near the roll assembly exit matches the upward-curving trajectory of the stainless steel sheet. When the sheet exits the roll assembly and begins to warp, the curved section flexibly guides the sheet, gradually changing its direction of movement along the curved trajectory, preventing a hard collision between the sheet and the baffle. The vertical section continues to provide stable obstruction after the sheet completes its curved transition, allowing the sheet to be smoothly unloaded into a cylinder at the limiting baffle. This effectively solves the problems of sheet damage due to collision and poor unloading, improving product quality and production efficiency.

[0020] Preferably, the unloading mechanism further includes an unloading conveying device, which is disposed on the discharge side of the rolling mechanism, and the starting end of the unloading conveying device corresponds to the discharge end of the rolling roller assembly.

[0021] By adopting the above solution, a discharge conveyor device is installed on the discharge side of the rolling mechanism. This device enables automatic conveying of the stainless steel drum after discharge, eliminating the need for manual handling and waiting. This significantly shortens material transfer time, allowing the fully automatic rolling machine to operate at a higher frequency and effectively improving the overall production efficiency of the stainless steel drum for washing machines. Furthermore, the stable mechanical conveying avoids quality problems such as deformation and scratches caused by improper manual operation during the transfer process, ensuring that each rolled drum enters the subsequent processing stage in good condition, thus improving product qualification rate and consistency.

[0022] Preferably, the unloading conveying device is a conveyor belt, and a limit bar is provided on the surface of the conveyor belt, the length direction of which is parallel to the axial direction of the rolling roller assembly.

[0023] By adopting the above solution, the conveyor belt has continuous and stable conveying characteristics, and can convey the rolled stainless steel cylinder from the discharge side of the rolling mechanism to the next process at a constant speed. Limiting bars parallel to the axial direction of the rolling roller group are set on the surface of the conveyor belt. The limiting bars form a lateral constraint on the stainless steel cylinder, restricting the rolling of the cylinder during the conveying process and ensuring that the cylinder is stably conveyed along the predetermined path. This solves the problems of unstable cylinder conveying and inaccurate positioning, and ensures the smoothness and efficiency of the production process.

[0024] In summary, this application has the following beneficial effects: 1. This technology achieves high efficiency and safety in the rolling process of stainless steel sheets through the coordinated operation of automated feeding and rolling mechanisms. The feeding and conveying device works in conjunction with the moving device, using a multi-point symmetrical adsorption structure and adjustable vacuum suction cups to achieve precise gripping and transfer of the sheet material, avoiding manual contact with sharp edges. At the same time, the limiting components guide and position the sheet material to ensure accurate entry into the rolling roller group, reducing the risk of workplace injuries, minimizing manual labor time, and improving continuous production efficiency.

[0025] 2. The rolling mechanism adopts an adjustable bushing type rolling and positioning roller collaborative design. It achieves stable rolling of plates of different thicknesses through precise roller clamping gap, controls the diameter and roundness error of the cylinder, and reduces the scrap rate. The adjustable bushing spacing structure is suitable for various specifications of plates without the need to change equipment, improving the equipment versatility and production flexibility.

[0026] 3. The rolling mechanism adopts an adjustable bushing type rolling and positioning roller collaborative design, which realizes stable rolling of plates of different thicknesses through precise roller clamping gap, controls the cylinder diameter and roundness error, and reduces the scrap rate; the adjustable bushing spacing structure is suitable for various specifications of plates, without the need to change equipment, improving the equipment versatility and production flexibility.

[0034] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0035] Reference Figure 1 as well as Figure 2 Embodiment 1 of this application discloses a fully automatic rolling machine for producing stainless steel drums for washing machine inner tubs. It includes a feeding mechanism 1, a rolling mechanism 2, and an unloading mechanism 3 connected in sequence. The feeding mechanism 1 can be connected to the previous production process of cutting stainless steel plates. The starting end of the feeding mechanism 1 is placed with stacks of cut stainless steel plates, which are automatically conveyed to the rolling mechanism 2 for rolling. The unloading mechanism 3 cooperates with the rolling mechanism 2 to automatically unload the rolled stainless steel drum to the next production process.

[0036] Reference Figure 2The feeding mechanism 1 includes a feeding conveyor 11 and a moving device 12. The feeding conveyor 11 is located on the feeding side of the rolling mechanism 2, and its end corresponds to the feeding end of the rolling mechanism 2. The moving device 12 is located above the feeding conveyor 11 and is used to move the stainless steel sheet on the feeding conveyor 11. In this embodiment, the feeding conveyor 11 adopts a roller conveyor line, and has an actively rotating roller shaft at least at the end of the roller conveyor line to provide power to drive the stainless steel sheet at the end of the roller conveyor line into the rolling mechanism 2. A limiting component 111 is mounted on the feeding conveyor 11, and the limiting component 111 forms a limiting channel 112 aligned with the entrance of the rolling roller group 22. In this embodiment, the limiting component 111 is configured as two upright plates mounted on the roller conveyor line, and the lower edge of the upright plates is configured to have an arc-shaped notch so that the lower edge can be inserted into the roller shaft gap of the roller conveyor line, thereby effectively limiting the stainless steel sheet on the feeding conveyor 11.

[0037] Referring to Figure 3, the moving device 12 includes a suspension frame 121, a moving frame 122, and an adsorption assembly 123. The suspension frame 121 is disposed above the feeding conveyor 11, and the moving frame 122 is movably connected to the suspension frame 121. The moving frame 122 can move horizontally along the width direction of the feeding conveyor 11 or vertically up and down. In this embodiment, the suspension frame 121 is supported and erected above the feeding conveyor 11 by a vertical pole. In other equivalent embodiments, the suspension frame 121 can also be adapted to specific production scenarios and disposed on other base surfaces that can provide support, or the structure at its base surface can be used directly as the suspension frame 121 to install the moving frame 122. The moving frame 122 is mounted on the suspension frame 121 by a suitable drive structure, which can use existing guide rails and telescopic cylinders to enable the moving frame 122 to move horizontally and vertically on the suspension frame 121.

[0038] Reference Figure 1 as well as Figure 3 At least two adsorption components 123 are provided. One end of each adsorption component 123 is fixed to the movable frame 122, and the other end faces the feeding conveyor 11. The other end of each adsorption component 123 is the adsorption surface. Further, the adsorption components 123 are arranged in two rows, with at least two in each row. The two rows of adsorption components 123 correspond to the long side of the stainless steel plate, and the adsorption components 123 in each row are evenly spaced. Each adsorption component 123 includes a connecting rod 124 and a vacuum suction cup 125. One end of the connecting rod 124 is fixed to the movable frame 122, and the other end faces the feeding conveyor 11. The vacuum suction cup 125 is fixed to the other end of the connecting rod 124, and its adsorption surface is parallel to the surface of the feeding conveyor 11. In this embodiment, the connecting rod 124 is a screw, which allows the effective connection length of the connecting rod 124 to be adjusted, thus providing more adaptability.

[0039] Reference, 2 and Figure 4 The rolling mechanism 2 includes a frame 21, a rolling roller assembly 22, and a drive device 23. The rolling roller assembly 22 is mounted on the frame 21, and the drive device 23 is located on one side of the frame 21. The output end of the drive device 23 is connected to one end of the rolling roller assembly 22 to drive the rolling roller assembly 22 to rotate. In this embodiment, the drive device 23 uses a motor and chain in conjunction with gears at the ends of the roller shafts of the rolling roller assembly 22 to form a drive. The rolling roller assembly 22 includes a positioning roller 221 and a pressing roller 222. The positioning roller 221 is located on the frame 21 near the front of the feeding conveyor 11. The positioning roller 221 includes a pair of vertically parallel roller shafts, and the gap between the positioning roller 221 and the surface of the feeding conveyor 11 is flush. The pressing roller 222 is located behind the positioning roller 221, and the gap between the pressing roller 222 and the gap between the pressing roller 222 and the positioning roller 221 are aligned. In this embodiment, the pressing roller 222 is a three-axis symmetrical pressing roller. The upper roller of the rolling pressure roller 222 includes a shaft core 223 and two bushings 224. The shaft core 223 is rotatably mounted on the frame 21 and connected to the drive device 23. The two bushings 224 are fitted onto the shaft core 223 with adjustable spacing. The two bushings 224 cooperate with the two lower rollers of the rolling pressure roller 222 to roll the long side of the stainless steel sheet.

[0040] Reference Figure 1 as well as Figure 2 The unloading mechanism 3 includes a limiting baffle 31 and an unloading conveying device 32. The limiting baffle 31 includes a continuous arc-shaped portion 311 and a vertical portion 312. The limiting baffle 31 is vertically mounted on the frame 21 and is located above the rolling mechanism 2. The surface of the limiting baffle 31 faces the front and rear sides of the rolling mechanism 2, and its bottom edge is adjacent to the outlet of the rolling roller group 22. The arc-shaped portion 311 of the limiting baffle 31 is located near the outlet of the rolling roller group 22, and the vertical portion 312 is located above the arc-shaped portion 311. The unloading conveying device 32 is located on the discharge side of the rolling mechanism 2, and the starting end of the unloading conveying device 32 corresponds to the discharge end of the rolling roller group 22. In this embodiment, the unloading conveyor 32 is a conveyor belt, the belt surface of which is a nylon belt with certain resistance and flexibility, and a limit bar 33 is provided on the belt surface, the length direction of which is parallel to the axial direction of the rolling roller group 22.

[0041] The implementation principle of a fully automatic rolling machine according to an embodiment of this application is as follows: During the production of the stainless steel tub body for the washing machine inner drum, a stack of cut stainless steel sheets is placed on one end of the feeding conveyor 11 and then moved to the underside of the moving device 12. The moving frame 122 of the moving device 12 descends, causing the adsorption component 123 to contact and adhere to the uppermost stainless steel sheet. Subsequently, the moving frame 122 rises, lifting the uppermost stainless steel sheet. The moving frame 122 moves above the limiting channel 112 formed by the limiting component 111, carrying the stainless steel sheet. Then, the moving frame 122 descends, placing the stainless steel sheet into the limiting channel 112 for conveying. Since the limiting channel 112 corresponds to the inlet of the rolling roller group 22, the stainless steel sheet in the limiting channel 112 is conveyed to the rolling roller group 22 for rolling and pressing by the conveying device. The moving device 12 is equipped with two rows of adsorption components 123, each with at least two evenly spaced components, corresponding to the long side of the sheet, to achieve multi-point, symmetrical adsorption of the sheet.

[0042] The positioning roller 221 is equipped with a pair of parallel roller shafts arranged vertically to form a roller clamping gap, and is flush with the surface of the feeding conveyor 11. This allows for precise horizontal positioning of the stainless steel sheet conveyed from the limiting channel 112, ensuring the sheet is in the correct position before entering the rolling process. Following the positioning roller 221 is the rolling pressure roller 222, whose entry roller clamping gap aligns with that of the positioning roller 221, ensuring a smooth transition of the sheet from the positioning roller 221 to the rolling pressure roller 222. The rolling pressure roller 222 applies pressure to the positioned sheet to roll it into a circle. Through precise roller clamping gap design and cooperation with the positioning roller 221, it can stably roll stainless steel sheets of different thicknesses and sizes, achieving high-quality rolling processing. The upper roller of the pressing roller 222 is configured with two bushings 224 sleeved on the shaft core 223. The shaft core 223 drives the bushings 224 to rotate, and the bushings 224 and the two lower rollers press the edge of the stainless steel sheet to form a cylindrical body.

[0043] A vertically supporting limiting baffle 31 is installed above the rolling mechanism 2. During the rolling process of the stainless steel drum of the washing machine, due to the elasticity of the sheet material and the rolling stress, the stainless steel arc-shaped sheet exiting from the rolling roller group 22 will warp upwards. When gradually rolled into a cylindrical shape, it is very easy for it to buckle back into the rolling roller group 22. By setting a vertical limiting baffle 31 above the rolling mechanism 2, the limiting baffle 31 forms a physical block on the upwardly warped stainless steel arc-shaped sheet, changing the movement trajectory of the sheet material and preventing it from buckling back into the rolling roller group 22. The sheet material can be smoothly formed into a cylinder on the exit side of the rolling roller group 22 and directly unloaded. An unloading conveyor device 32 is set on the discharge side of the rolling mechanism 2. The unloading conveyor device 32 realizes the automatic conveying of the stainless steel drum after unloading. A limiting baffle 33 parallel to the axial direction of the rolling roller group 22 is set on the conveyor belt surface. The limiting baffle 33 forms a lateral constraint on the stainless steel drum, restricting the rolling of the drum during the conveying process and ensuring that the drum is stably conveyed along the predetermined path.

[0044] This application embodiment achieves efficient and safe production of stainless steel sheet rolling through the collaborative design of an automated feeding mechanism 1 and a rolling mechanism 2: the feeding conveyor 11 and the moving device 12 work together to accurately grasp and transfer the sheet metal using multi-point symmetrical adsorption and an adjustable vacuum suction cup 125, combined with the guiding and positioning of the limiting component 111 to avoid manual contact with sharp edges and reduce time loss; the rolling mechanism 2 uses adjustable bushings 224 type rolling rollers 222 and positioning rollers 221, and controls the rolling accuracy through precise roller clamping gaps, and the bushing spacing 224 is adjustable to adapt to various sheet metals; a limiting baffle 31 is cleverly designed above the rolling roller group 22, and the limiting baffle 31, with its arc-shaped part 311 and vertical part 312, prevents the sheet metal from buckling and getting stuck, and the unloading conveyor 32 stabilizes the conveying cylinder through the limiting baffle 33, realizing automatic material transfer and improving production efficiency and product qualification rate.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
