Description

Technical Field

[0001] The invention relates to the technical field of tinplate coiling equipment, and in particular to a tinplate coiling and feeding mechanism. Background Art

[0002] The existing tinplate is a kind of coated steel plate, which is often used to be processed into various packaging cans. Coated steel plate is also called plated steel plate. It is a general term for products coated with Sn, Zn, Al, Cr, Pb-Sn alloy, organic coating and plastic on the surface of low-carbon steel plate with good deep drawing performance.

[0003] When tin-plated sheets are produced and processed, they need to be wound for subsequent transportation, placement and use. When winding the sheets, one side of the sheets needs to be fixed on the winding device, and then the sheets are wound by rotating the winding device. In this process, not only one end of the sheets needs to be fixed, but the fixed end also needs to be released after winding, and then the wound sheets can be removed.

[0004] In the prior art, it is rather troublesome to fix one end of the thin plate. After all, it is difficult to release the fixing portion after the thin plate is wound, resulting in difficulty in removing the thin plate from the winding device, causing the wound thin plate to become loose, or even deformation at the contact position with the winding device, which not only affects the winding efficiency of the thin plate, but also easily causes quality problems with the thin plate.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0039] Please refer to 1-10, a tin-plated sheet winding and feeding mechanism, including a support frame 1 and multiple receiving trays 2, wherein a first gear rod 3 is slidably provided on one of the receiving trays 2, a pressing rod 31 is slidably provided on the first gear rod 3, a fixing groove 21 is provided on the receiving tray 2, the pressing rod 31 is slidably provided in the fixing groove 21, and the pressing rod 31 presses and fixes one end of the sheet; a baffle 32 is slidably provided on the first gear rod 3, a sliding groove 22 is provided on the receiving tray 2, the baffle 32 is slidably provided in the sliding groove 22, and the baffle 32 abuts against the sheet; a second spring 34 is provided between the first gear rod 3 and the receiving tray 2, and the two ends of the second spring 34 are fixedly connected to the first gear rod 3 and the receiving tray 2 respectively; the first gear rod 3 is rotatably provided on the receiving tray 2 The wheel 23 is fixedly provided with a square tube 4 on the support frame 1, and a second toothed rod 41 is slidably provided on the square tube 4. The first toothed rod 3 and the second toothed rod 41 are both meshed and transmitted with the first gear 23, and the second toothed rod 41 is provided with a disengagement portion 42; it also includes a tensioning assembly, which is used to adjust the tension of the receiving tray 2, and when the tension of the receiving tray 2 is adjusted, the fixing and relaxation of one end of the thin plate are completed. When one end of the thin plate is fixed, the receiving tray 2 is opened through the tensioning assembly. During the opening process, the first gear 23 is meshed and transmitted with the upper end of the disengagement portion 42, so that the first toothed rod 3 slides upward under the rotation of the first gear 23, and compresses the second spring 34. In the process of sliding upward, the block The plate 32 extends out from the sliding groove 22, and the pressing rod 31 moves up from the bending part of the fixed groove 21 to disengage from the fixed groove 21, and one end of the thin plate passes through between the pressing rod 31 and the fixed groove 21, abuts against the baffle 32, and then the receiving tray 2 is tightened by the tensioning assembly. During this process, the first gear rod 3 is reset, and the thin plate is pressed by the pressing rod 31 and pressed into the fixed groove 21. The pressing rod 31 is located at the bending part of the fixed groove 21, and the baffle 32 is retracted into the sliding groove 22. At this time, the receiving tray 2 can be rotated to complete the winding of the thin plate; after the winding is completed, the receiving tray 2 is tightened by the tensioning assembly. During this process, the first gear 23 is meshed with the lower part of the disengagement portion 42 for transmission, so that the first gear rod 3 moves down. , the second spring 34 is stretched, and the pressing rod 31 is made to slide to the bottom of the fixing groove 21, the pressing rod 31 is separated from the bottom of the fixed end of the thin plate, and the thin plate loses the pressure of the pressing rod 31. As the receiving tray 2 is tightened, the fixed end of the thin plate is separated from the fixing groove 21, and the wound thin plate can be removed. By setting the pressing rod 31, one end of the thin plate is fixed before winding and relaxed after winding, so that when the thin plate is wound, the fixing of the thin plate is more convenient, and after winding, the thin plate can be removed more quickly, avoiding the problem that the fixed end of the wound thin plate is difficult to relax when being removed, resulting in the looseness or even deformation of the wound thin plate, which not only improves the winding efficiency of the thin plate, but also improves the winding quality of the thin plate.

[0040] When the first gear 23 is located at the disengagement portion 42, the second spring 34 is in a normal state. At this time, the pressing rod 31 is at the bending portion of the fixing groove 21, and when the pressing rod 31 is at the bending portion of the fixing groove 21, the thin plate is pressed and fixed. When the pressing rod 31 is at the bottom of the fixing groove 21, the thin plate is not pressed and fixed. When the pressing rod 31 rises to disengage from the fixing groove 21, the baffle 32 extends out of the sliding groove 22, which is convenient for controlling the pressing position of the thin plate when fixing one end of the thin plate, thereby improving the portability when fixing the thin plate.

[0041] Specifically, a first spring 33 is provided between the pressing rod 31 and the first gear rod 3, and both ends of the first spring 33 are fixedly connected to the pressing rod 31 and the first gear rod 3 respectively. When the pressing rod 31 moves from the bending part of the fixing groove 21 to the bottom of the fixing groove 21, the first spring 33 is compressed, and when the pressing rod 31 is disengaged from the fixing groove 21, the pressing rod 31 is aligned with the fixing groove 21 through the first spring 33, thereby preventing the pressing rod 31 from being skewed and misaligned with the fixing groove 21.

[0042] In an embodiment further provided by the present invention, a third spring 35 is arranged between the baffle plate 32 and the first gear rod 3, and the two ends of the third spring 35 are fixedly connected to the baffle plate 32 and the first gear rod 3 respectively. When the pressing rod 31 is located at the bending position of the fixed groove 21, the baffle plate 32 is located in the sliding groove 22. When the pressing rod 31 moves from the bending position of the fixed groove 21 to the bottom of the fixed groove 21, the baffle plate 32 does not move, and the third spring 35 is compressed, so that the baffle plate 32 does not restrict the downward movement of the pressing rod 31 and the first gear rod 3.

[0043] Furthermore, a bolt 43 is rotatably provided on the square tube 4, and the bolt 43 is threadedly connected to the second gear rod 41. When the first gear 23 is located at the disengagement portion 42, the pressing rod 31 presses and fixes the thin plate, that is, the receiving tray 2 can be rotated at this time to complete the winding of the thin plate. The bolt 43 rotates to control the height of the second gear rod 41, so that when the receiving tray 2 is opened to any extent, the first gear 23 can be aligned with the disengagement portion 42 of the second gear rod 41, so that the receiving tray 2 can be suitable for the winding inner diameters of a variety of thin plates when winding the thin plates, thereby improving the applicability.

[0044] Furthermore, a scale is provided on the square tube 4, and the scale is adapted to the second gear rod 41. When adjusting the height of the second gear rod 41, the height of the second gear rod 41 can be better controlled by observing the second gear rod 41 and the scale, that is, the inner diameter required for winding the thin plate can be better adjusted, thereby improving the operational portability when winding the thin plate.

[0045] In an embodiment further provided by the present invention, the tensioning assembly includes a bidirectional screw 5 rotatably arranged on the support frame 1, sliding blocks 51 are threadedly arranged at different threaded positions on both sides of the bidirectional screw 5, a rotating block 52 is rotatably arranged on the sliding block 51, a connecting rod 53 is arranged between the rotating block 52 and each receiving tray 2, and the two ends of the connecting rod 53 are rotatably connected to the rotating block 52 and the receiving tray 2 respectively, an adjusting motor 54 is fixedly arranged on the support frame 1, and the motor shaft of the adjusting motor 54 is fixedly connected to the bidirectional screw 5, when the adjusting motor 54 drives the bidirectional screw 5 to rotate, the sliding block 51 slides, and the opening and tightening of the receiving tray 2 is controlled by the connecting rod 53, and by setting the rotating block 52, the bidirectional screw 5 will not drive the receiving tray 2 to rotate when it rotates, so that the opening and tightening of the receiving tray 2 are more convenient and quick.

[0046] In the embodiment provided by the present invention, a rotating ring 6 is rotatably provided on the bidirectional screw 5, and a plurality of limiting tubes 62 are fixedly provided on the rotating ring 6. The plurality of limiting tubes 62 correspond one by one to the plurality of receiving trays 2 and are slidably connected thereto. By providing the limiting tubes 62, they are slidably connected thereto and the receiving trays 2, so that the receiving trays 2 are more stable when opened and tightened.

[0047] Specifically, a limit rod 61 is fixedly provided on the rotating ring 6, and the limit rod 61 is slidably connected to the rotating block 52. A ring gear 63 is fixedly provided on the limit rod 61, and the ring gear 63 is rotatably connected to the support frame 1. A second gear 7 is rotatably provided on the support frame 1, and the second gear 7 is meshed with the ring gear 63 for transmission. A driving motor 71 is fixedly provided on the support frame 1, and the motor shaft of the driving motor 71 is fixedly connected to the second gear 7. The driving motor 71 drives the second gear 7 and the ring gear 63 to rotate, so that the ring gear 63 rotates with the limit rod 61. When the limit rod 61 rotates, it drives the rotating block 52, the rotating ring 6, the connecting rod 53 and the limit tube 62 to rotate, so that the receiving tray 2 rotates without affecting the sliding block 51 and the bidirectional screw 5.

[0048] In the present invention, the provided adjustment motor 54 and drive motor 71 are both brake motors, which are in a locked state when not actively rotating. When the adjustment motor 54 rotates to rotate the bidirectional screw 5, the ring gear 63, the limit rod 61, the rotating ring 6, and the rotating block 52 are all in a locked state under the action of the drive motor 71, and will not rotate with the rotation of the bidirectional screw 5. Conversely, when the drive motor 71 rotates, the bidirectional screw 5 will not rotate with the rotation of the rotating block 52 and the rotating ring 6.

[0049] Working principle: When winding the thin plate, turn the bolt 43, adjust the height of the second gear rod 41 according to the scale set on the square tube 4, and then adjust the motor 54 to start, drive the bidirectional screw 5 to rotate, make the sliding block 51 slide, and open the receiving tray 2 through the connecting rod 53. When the receiving tray 2 is opened to the point where the first gear 23 is located at the disengagement portion 42 of the second gear rod 41, the second spring 34 is in a normal state, the baffle 32 is located in the sliding groove 22, and the pressing rod 31 is located at a fixed turning point. At this time, the radius of the receiving tray 2 is the thin plate winding. The inner circle radius after winding; then the adjusting motor 54 continues to drive the steering screw rod to rotate, so that the receiving tray 2 continues to open, at this time the first gear 23 meshes and transmits with the upper part of the disengaging portion 42, the first gear 23 rotates, the first gear rod 3 slides, and the second spring 34 is compressed. Under the action of the first gear rod 3, the baffle plate 32 extends, and the pressing rod 31 is disengaged from the fixing groove 21, and then one end of the thin plate is passed between the pressing rod 31 and the fixing groove 21, and abuts against the baffle plate 32. At this time, the adjusting motor 54 is reversed to tighten the receiving tray 2. The first gear 23 is restored to the position where the disengagement portion 42 is located. During the tightening process of the receiving tray 2, the pressing rod 31 presses one end of the thin plate and presses it into the fixing groove 21. At the same time, the baffle 32 is retracted into the sliding groove 22 to complete the fixation of one end of the thin plate. Subsequently, the driving motor 71 is started, and the gear ring 63 is driven to rotate through the second gear 7, so that the gear ring 63 drives the rotating block 52 and the rotating ring 6 to rotate through the limiting rod 61, so that the receiving tray 2 can be rotated to wind the thin plate; after the thin plate is wound, the adjusting motor 54 is started to drive the bidirectional screw 5 is rotated to reduce the radius of the receiving tray 2. During the tightening process, the first gear 23 meshes with the lower part of the disengaging portion 42 and transmits, so that the first gear rod 3 moves downward and the second spring 34 is stretched. At this time, the third spring 35 is compressed, and the baffle 32 does not move. As the first gear rod 3 moves downward, the pressing rod 31 compresses the first spring 33 and slides to the bottom of the fixing groove 21 and disengages from the thin plate. When the receiving tray 2 is tightened, the fixed end of the thin plate is disengaged from the fixing groove 21, and the thin plate that has been wound can be removed.

[0050] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
