Description

Technical Field

[0001] This invention belongs to the technical field of metal plate processing equipment, specifically relating to a feeding device for a roll forming machine. Background Technology

[0002] A tile forming machine is a production line consisting of feeding, forming, and post-forming cutting. Its colored tiles have a smooth and beautiful appearance, uniform paint texture, high strength, and durability, making them widely used in industrial and civil buildings such as factories, warehouses, stadiums, exhibition halls, and theaters for roofs and walls. The feeding device of the tile forming machine is located in front of the forming device and is used to guide and convey the metal sheet. Currently, to ensure the accuracy and stability of the sheet's position during conveying, the feeding device of the tile forming machine uses a through groove for the guide rollers to guide the sheet, and a groove is set in the middle of the guide rollers to ensure the stability of the metal sheet during conveying. However, the groove also causes inconvenience for feeding in the initial state of the tile forming machine. When feeding, to avoid jamming the guide rollers, the sheet needs to be kept parallel to the conveying rollers during movement, requiring manual pulling of the sheet backward. The operation process is relatively complicated and results in low feeding efficiency. Summary of the Invention

[0043] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0044] Please refer to the following: Figure 1 and Figure 2 The feeding device for a roll forming machine provided by the present invention will now be described. The feeding device for the roll forming machine includes a conveying frame 1, a clamping assembly 2, and a pushing assembly 3. At least two sets of conveying assemblies 11 are provided on the conveying frame 1, and the two or more sets of conveying assemblies 11 are spaced apart. The two adjacent conveying assemblies 11 form a clamping gap that is set along the conveying direction in the length direction. The clamping assembly 2 is located at the clamping gap and is slidably disposed on the conveying frame 1 along the length direction of the clamping gap for clamping the metal plate. The pushing assembly 3 is disposed between the clamping assembly 2 and the conveying frame 1 for driving the clamping assembly 2 to slide on the conveying frame 1.

[0045] Compared with the prior art, the feeding device for the roll forming machine provided in this embodiment features a conveyor frame 1 with at least two sets of conveying components 11 arranged side-by-side. The conveying components 11 are preferably roller conveyors. The gap between adjacent sets of conveying components 11 accommodates the clamping components 2. Guide wheels 262 with guide grooves are provided on both sides of the conveyor frame 1. The operator can place the sheet material to be fed onto the conveyor frame 1 guided by the guide wheels 262 at the feed inlet. The clamping components 2 are then moved to the feed inlet by the pushing component 3 to clamp the edge of the sheet material. Simultaneously, the pushing component 3 drives the clamping component 2 to move the sheet material backward, reducing unnecessary manual dragging operations, making operation convenient and saving manpower.

[0046] Preferably, in this embodiment, the clamping part of the clamping component 2 is located between the two conveying components 11, which can avoid interference between the clamping part and the conveying component 11.

[0047] In some embodiments, the clamping component 2 described above may employ, for example... Figures 1 to 5 The structure shown. See also... Figures 1 to 5 The clamping assembly 2 includes an annular frame 21, a fixing plate 22, a pressure plate 23, and a clamping assembly 24. The annular frame 21 is fitted onto the conveyor frame 1 and slidably disposed on the conveyor frame 1 along the conveying direction. The fixing plate 22 is installed at the bottom of the annular frame 21, and its top surface is flush with the conveying surface of the conveyor assembly 11. The pressure plate 23 is movably disposed above the fixing plate 22 in a vertical direction. The clamping assembly 24 is disposed between the annular frame 21 and the pressure plate 23, and is used to drive the pressure plate 23 to move on the annular frame 21. The annular frame 21 is fitted onto the outside of the conveyor frame 1 and can be slidably disposed on the conveyor frame 1 along the conveying direction. The two sides of the annular frame 21 are guide portions that slidably engage with the sides of the conveyor frame 1. The top of the annular frame 21 is a top plate for mounting the pressure plate 23, and the bottom of the annular frame 21 is a bottom plate for mounting the fixing plate 22. Both the fixing plate 22 and the pressure plate 23 are located at the clamping gap. In use, the ring frame 21 is moved to the feeding port by the pushing component 3. The operator drags the sheet material above the fixed plate 22, and the clamping component 24 drives the pressure plate 23 to move closer to the fixed plate 22, pressing the edge of the sheet material between the fixed plate 22 and the pressure plate 23. After pushing the sheet material to the rear, the clamping component 24 drives the pressure plate 23 to move upward, releasing the sheet material. The ring frame 21 can then move to the feeding port to clamp and pull the sheet material behind it. The structure is simple and the operation is convenient.

[0048] Preferably, in this embodiment, a roller is provided on the guide portion of the annular frame 21 and is rotatably disposed on the side of the conveyor frame 1.

[0049] Specifically, in this embodiment, a buffer pad is provided at the bottom of the pressure plate 23. The buffer pad is made of polyurethane, which can prevent the plate from being cut and can also enhance the friction between the plate and the plate when it is clamped.

[0050] In some embodiments, the clamping assembly 24 may employ, for example... Figure 2 , Figure 3 and Figure 5 The structure shown. See also... Figure 2 , Figure 3 and Figure 5 The clamping assembly 24 includes a movable rod 241, a driving rod 242, and a driving assembly. One end of the movable rod 241 is fixedly connected to the pressure plate 23, and the other end is slidably mounted on the annular frame 21 in a vertical direction. A guide surface is provided on the top of the movable rod 241. The driving rod 242 is slidably mounted on the annular frame 21 in a horizontal direction. A driving surface that slides and engages with the guide surface is provided on the driving rod 242. When the driving rod 242 slides on the annular frame 21, the engagement between the driving surface and the guide surface drives the movable rod 241 to move in a vertical direction. The driving assembly is located between the driving rod 242 and the annular frame 21 and is used to drive the driving rod 242 to slide on the annular frame 21. A sliding sleeve 211 is mounted on the top plate of the annular frame 21 in a vertical direction. The movable rod 241 is slidably mounted inside the sliding sleeve 211, and a clearance is provided on the side wall of the sliding sleeve 211 to allow the driving rod 242 to pass. A driving surface is provided on the bottom surface of the drive rod 242. When the drive rod 242 slides on the annular frame 21, it can slide into the sliding sleeve 211, and the driving surface abuts against the guide surface, thereby driving the movable rod 241 to move downward. This allows the pressure rod at the end of the movable rod 241 to press the plate onto the fixed plate 22. The movement of the drive rod 242 is driven by the drive assembly. The pressing and releasing of the plate are achieved through the reciprocating movement of the drive rod 242.

[0051] In some embodiments, the aforementioned driving component may employ, for example... Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 The drive assembly includes a drive wheel 25 and a swing assembly 26. The drive wheel 25 is rotatably mounted on the ring frame 21 and meshes with the drive rod 242. The swing assembly 26 is positioned between the drive wheel 25 and the ring frame 21 to drive the drive wheel 25 to rotate. The drive wheel 25 is rotatably positioned above the drive rod 242. Teeth are provided on the outer side of the drive wheel 25. Teeth are provided on the upper surface of the drive rod 242 to mesh with the teeth on the drive wheel 25. The reciprocating rotation of the drive wheel 25 drives the drive rod 242 to swing back and forth. When the drive wheel 25 reciprocates, the swing assembly 26 drives the drive wheel 25 to rotate back and forth in two directions.

[0052] In some embodiments, the aforementioned swing component 26 may employ, as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 The swing assembly 26 includes a swing rod 261 and a guide plate 263. One end of the swing rod 261 is fixedly connected to the drive wheel 25, and the other end is rotatably equipped with a guide wheel 262. The guide plate 263 is arranged along the length of the clamping gap and is mounted on the conveyor frame 1. The bottom of the guide plate 263 is provided with a guide surface that abuts against the guide wheel 262, and both ends of the guide surface are provided with inclined upward transition surfaces. The guide plate 263 is mounted on the top of the swing rod 261, and the axis of the guide wheel 262 is arranged in a horizontal direction and perpendicular to the length direction of the guide surface. The guide wheel 262 is rotatably mounted on the swing rod 261 and rolls on the guide surface.

[0053] Specifically, when the annular frame 21 is located at the inlet, the guide wheel 262 rolls on the transition surface in front of the guide plate 263 and gradually swings towards the inlet as it moves, thereby indirectly driving the pressure plate 23 to press the steel plate. When it moves to the rear of the conveyor frame 1, the guide wheel 262 moves to the transition surface behind the guide plate 263, and under the reverse force of the plate, the swing rod 261 swings upward, causing the pressure plate 23 to release the plate. When the annular frame 21 moves back towards the inlet, the swing rod 261 swings in the opposite direction through the guidance of the transition surface. This avoids interference between the pressure plate 23 and the plate during the return stroke.

[0054] In some embodiments, the aforementioned swing arm 261 may be as follows: Figure 2 , Figure 3 and Figure 4 The structure shown. See also... Figure 2 , Figure 3 and Figure 4 When the guide wheel 262 abuts against the guide surface, the swing rod 261 is set at an angle along the vertical direction, and the annular frame 21 is provided with a guiding component 27 for driving the swing rod 261 to swing vertically. This component ensures that the swing rod 261 is always subjected to a force that swings vertically. When the guide wheel 262 swings to the transition surface, the guiding component 27 can keep the guide wheel 262 in contact with the transition surface until the swing rod 261 rotates to a vertical position. When the annular frame 21 moves in the opposite direction, the swing rod 261 swings in the opposite direction to the movement direction of the annular frame 21 through the guide of the transition surface, thereby switching the movement direction of the pressure plate 23. This allows for the clamping or loosening of the plate material while switching the movement direction of the annular frame 21.

[0055] Optionally, in this embodiment, an elongated guide groove for accommodating the guide wheel 262 is provided on the guide plate 263. The top surface of the elongated guide groove is the guide surface and the transition surface. The bottom surface of the elongated guide groove is a plane that is parallel to the guide surface and the transition surface at intervals. By providing the elongated guide groove, the guide wheel 262 can only roll inside the elongated guide groove. When the guide wheel 262 moves to the transition surface, it can guide the swing rod 261 to switch the swing direction.

[0056] In some embodiments, the aforementioned guiding component 27 may employ, for example... Figure 4 The structure shown. See also Figure 4 The guiding assembly 27 includes a sliding sleeve 271, a correcting rod 272, and a pulling member 273. The sliding sleeve 271 is slidably mounted on the annular frame 21 in a vertical direction, and has a horizontal groove on it. One end of the correcting rod 272 is fixedly connected to the end of the swing rod 261 away from the guide wheel 262, and the other end is slidably mounted inside the groove. The pulling member 273 is located between the sliding sleeve 271 and the annular frame 21, and is used to pull the annular frame 21 downwards. A column for mounting the drive rod 242 is provided on the top plate of the annular frame 21. The sliding sleeve 271 is fitted onto the column and slidably mounted on it in a vertical direction. A rotating shaft is fixedly connected to the swing rod 261 for rotatably mounting on the annular frame 21. The rotating shaft is also fixedly connected to the correcting rod 272. When the swing rod 261 swings, it can drive the correcting rod 272 to swing together. When the swing rod 261 swings downward, the corrective rod 272 slides inside the groove, causing the sliding sleeve 271 to slide upward. Under the action of the pulling member 273, a downward sliding force is always applied to the sliding sleeve 271. This indirectly applies a rotational force to the swing rod 261 in the vertical direction.

[0057] Specifically, in this embodiment, the length directions of the swing rod 261 and the corrective rod 272 are in the same direction. Furthermore, the projections of the swing rod 261 and the corrective rod 272 along the axis of rotation are on the same straight line.

[0058] Specifically, in this embodiment, the pulling element 273 is a tension spring.

[0059] In some embodiments, the aforementioned actuating component 3 may employ, as follows: Figure 2 The structure shown. See also Figure 2The driving component 3 includes a sliding block 31, a lead screw 32, and a driving member. The sliding block 31 is slidably mounted on the conveyor frame 1 along the conveying direction, and the clamping component 2 is mounted on the sliding block 31. The lead screw 32 is rotatably mounted on the conveyor frame 1 and threadedly connected to the sliding block 31. The driving member is mounted on the conveyor frame 1, and its driving end is drive-connected to the lead screw 32 to drive the lead screw 32 to rotate. The sliding block 31 is slidably mounted on the bottom of the conveyor frame 1 via a guide rail, and an annular frame 21 is mounted on the sliding block 31. The driving member is a synchronous motor, and its driving end is drive-connected to the lead screw 32. The movement of the sliding block 31 is achieved by the driving member driving the lead screw 32 to rotate.

[0060] Preferably, in this embodiment, rollers are rotatably provided on the side wall of the annular frame 21 and rolled on the conveyor frame 1. Rollers are also provided on the bottom and top surfaces of the side of the conveyor frame 1, which can guide the annular frame 21 during movement and reduce swaying of the annular frame 21 during movement.

[0061] In some embodiments, the ring frame 21 described above can be adopted as follows: Figure 5 The structure shown. See also Figure 5 A pulley 243 is rotatably mounted on the ring frame 21, positioned above the movable rod 241 to facilitate the sliding of the drive rod 242 onto the movable rod 241. A clearance hole is provided on the sliding sleeve 211 of the top plate of the ring frame 21 to allow the drive rod 242 to pass. The pulley 243 is rotatably mounted above the clearance hole. The drive rod 242 is located inside the clearance hole and between the pulley 243 and the movable rod 241. When the drive rod 242 moves, it causes the pulley 243 to roll. The pulley 243 facilitates the movement of the drive rod 242 and provides support, allowing the drive rod 242 to stably apply force to the movable rod 241, thus improving stability during operation.

[0062] In some embodiments, the aforementioned movable lever 241 may be adopted as follows: Figure 6 The structure shown. See also Figure 6An elastic element 244 is provided between the movable rod 241 and the ring frame 21 to drive the movable rod 241 to move away from the pressure plate 23. A racetrack hole is provided on the outer wall of the sliding sleeve 211 on the ring frame 21, arranged vertically. A slider is fixedly installed on the pressure plate 23 and slidably disposed inside the sliding sleeve 211. A sliding rod is installed on the slider and slidably disposed inside the racetrack hole. The sliding rod extends out of the outer wall of the sliding sleeve 211, and one end of the elastic element 244 is installed on the end of the sliding rod located outside the sliding sleeve 211, while the other end is installed on the sliding sleeve 211 and located above the sliding rod. When the guide surface on the movable rod 241 moves relative to the driving surface on the driving rod 242, the sliding rod can drive the pressure plate 23 to move upward, creating a sufficient gap between the pressure plate 23 and the fixed plate 22 for the plate material to move.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
