Description

Technical Field

[0001] The present application relates to the technical field of coiling machines, and in particular to a lead plate coiling machine that is convenient for loading and unloading a coiling drum. Background Art

[0002] After the lead plate is produced, it needs to be coiled. At this time, a lead plate coil machine is needed. The lead plate coil machine can coil the lead plate coil into a specific shape and size, so as to produce lead plate products that meet the needs. By adjusting parameters such as the position, angle and speed of the working roller, the curling shape and size can be accurately controlled to meet the needs of different industries. However, some existing coil machines are more troublesome when dismantling the piles and winding the drum, and the structure is more complicated and less practical.

[0003] Patent No. CN 216613352 U discloses a lead sheet coil machine that is convenient for loading and unloading a winding drum, including a locking groove, a fixed block, an insertion groove, a bevel gear and a motor, etc. By providing a first spring and a second spring, a pull ring drives the second moving rod to move outward through a rope, so that the second moving rod is disengaged from the insertion groove, and the handle is pulled to drive the first moving rod to move upward, so that the moving rod drives the pulling handle to squeeze the first spring in the first sliding groove, and the moving rod is disengaged from the locking groove, which makes it easy to remove the second rotating rod from the locking groove, thereby facilitating the rapid replacement of the winding drum.

[0004] However, in use, there are the following defects:

[0005] Although the first movable rod and the second movable rod are used to block the first rotating rod on the winding drum so that it can keep rotating in the engaging groove, the two bevel gears need to be aligned and meshed each time the winding drum is disassembled to complete the installation limit. Due to the small tooth groove, alignment is more difficult and a staff member must observe carefully on one side, which affects the convenience and efficiency of disassembly and assembly. Utility Model Content

[0006] The purpose of the present application is to provide a lead sheet coil machine which is convenient for loading and unloading a winding drum, and solves the problem proposed in the background technology that although the first moving rod and the second moving rod are used to block the first rotating rod on the winding drum so that it can keep rotating in the engaging groove, each time the winding drum is disassembled and assembled, the two bevel gears need to be aligned and meshed to complete the installation limit. Since the tooth grooves are small, it is more difficult to align them, and a staff member must observe carefully from one side, which affects the convenience and efficiency of disassembly and assembly.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a lead sheet coil machine that is convenient for loading and unloading a winding drum, comprising a base, a support shaft, a winding drum and a limiting hole, wherein both sides of the top of the base are fixedly connected with support plates, the center of the side wall of the support plate is rotatably connected with the support shaft, and the surfaces on the opposite sides of the support shafts on both sides are fixedly connected with two arc blocks, the side walls of the arc blocks are penetrated with insertion holes, the left and right ends of the winding drum are fixedly connected with a center rod, the left and right surfaces of the center rod are penetrated with through holes, and the bottom of the surface of the center rod is fixedly connected with a convex strip, the center rod is movably placed between the two arc blocks, and an insertion rod is movably inserted into the inner sides of the through holes and the insertion holes, a limiting hole is provided on the surface of the insertion rod, and a telescopic groove is penetrated on the inner side of the arc block corresponding to the limiting hole, the inner side of the telescopic groove is laterally slidably connected to the limiting rod, and a spring is movably placed in the telescopic groove.

[0008] In this technical solution, the reel can be easily disassembled and assembled through the arc block, the center rod, the convex strip, the socket, the through hole and the insertion rod. The center rods at both ends of the reel are placed on the arc block, and the convex strip will be inserted into the gap between the two arc blocks like a knife, so that the center rod can be positioned without deliberate positioning, and the socket and the through hole are corresponding, so the insertion rod can be directly inserted along the socket and the through hole. The disassembly and assembly are convenient and fast, and the practicability is strong. At the same time, the insertion rod can be limited by the limiting hole, the telescopic slot, the spring and the limiting rod. The surface of the insertion rod is provided with a limiting hole. During the insertion process, the limiting rod will be stuck in the limiting hole, thereby limiting the insertion rod and preventing it from slipping out of the socket and the through hole. When disassembly is required, it is only necessary to pull the limiting rod to make the limiting rod slide out of the limiting hole. At this time, the insertion rod can be pulled out normally, thereby avoiding the insertion rod falling off during the winding process and causing the reel to lose the limit, thereby improving the stability and practicability of the device.

[0009] As an optional solution of the technical solution of the present application, the through hole and the plug hole are located in the same horizontal plane, and the through hole and the plug hole have the same size.

[0010] As an optional solution of the technical solution of the present application, the lower surface of the central rod is in contact with the inner arc surface of the arc block.

[0011] As an optional solution of the technical solution of the present application, one end of the limiting rod is located on the inner side of the limiting hole, and the other end of the limiting rod is located on the outer side of the other end of the telescopic slot.

[0012] As an optional solution of the technical solution of the present application, the width of the gap between the bottoms of the arc-shaped blocks is consistent with the width of the convex strips.

[0013] As an optional solution of the technical solution of the present application, a motor is fixedly mounted on one side of the top end of the base, and the outer end surface of the transmission shaft of the motor is transmission-connected to the support shaft via a crawler track.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application can facilitate the disassembly and assembly of the reel through the arc block, the center rod, the convex strip, the jack, the through hole and the insertion rod. The center rods at both ends of the reel are placed on the arc block, and the convex strip will be inserted into the gap between the two arc blocks like a knife, so that the center rod can be positioned without deliberate positioning, and the jack and the through hole are corresponding, so the insertion rod can be directly inserted along the jack and the through hole, which makes disassembly and assembly convenient and fast.

[0016] 2. The present application can limit the insertion rod through the limit hole, telescopic slot, spring and limit rod. The limit hole is provided on the surface of the insertion rod. During the insertion process, the limit rod will be stuck in the limit hole, thereby limiting the insertion rod and preventing it from slipping out of the insertion hole and the through hole. When disassembly is required, it is only necessary to pull the limit rod to make the limit rod slide out of the limit hole. At this time, the insertion rod can be pulled out normally, thereby preventing the insertion rod from falling off during the winding process and causing the reel to lose the limit, thereby improving the stability and practicality of the device.

Support plates 2 are fixedly connected to both sides of the top of the base 1, and the support shaft 5 is rotatably connected to the center of the side wall of the support plate 2. A motor 3 is fixedly installed on one side of the top of the base 1, and the outer end surface of the transmission shaft of the motor 3 is transmission-connected to the support shaft 5 through a crawler 4.

[0024] like Figure 2 and Figure 3 As shown, two arc blocks 8 are fixedly connected to the surfaces on the opposite sides of the support shafts 5 on both sides, and a socket 9 is penetrated through the side wall of the arc block 8. A center rod 7 is fixedly connected to the center of the left and right ends of the reel 6. A through hole 701 is penetrated through the left and right surfaces of the center rod 7. The through hole 701 and the socket 9 are located in the same horizontal plane, and the through hole 701 is consistent in size with the socket 9. After the center rod 7 is placed, the through hole 701 will automatically align with the socket 9, thereby facilitating the insertion of the insertion rod 10.

[0025] like Figure 2 As shown, the bottom of the surface of the center rod 7 is fixedly connected with a convex strip 702, and the center rod 7 is movably placed between the two arc blocks 8. The lower surface of the center rod 7 fits with the inner arc surface of the arc block 8, and the width of the gap between the bottoms of the arc blocks 8 is consistent with the width of the convex strip 702. The convex strip 702 will slide into the gap, thereby completing the fitting of the center rod 7 and the arc block 8. There is no need for deliberate positioning, and the operation is convenient.

[0026] like Figure 2 and Figure 3 As shown, an insertion rod 10 is movably inserted into the inner side of the through hole 701 and the insertion hole 9, a limiting hole 11 is provided on the surface of the insertion rod 10, and a telescopic groove 12 is provided on the inner side of the arc block 8 corresponding to the limiting hole 11, a limiting rod 14 is laterally slidably connected to the inner side of the telescopic groove 12, and a spring 13 is movably placed inside the telescopic groove 12, one end of the limiting rod 14 is located on the inner side of the limiting hole 11, and the other end of the limiting rod 14 is located on the outer side of the other end of the telescopic groove 12, and the spring 13 is in an extruded state, which will push the limiting rod 14 into the limiting hole 11.

[0027] In actual use, the center rod 7 at both ends of the reel 6 is placed on the arc block 8, and the convex strip 702 will be inserted into the gap between the two arc blocks 8, so that the center rod 7 can be positioned without deliberate positioning, and the socket 9 and the through hole 701 are corresponding, so the insertion rod 10 can be directly inserted along the socket 9 and the through hole 701. The disassembly and assembly are convenient and fast, and the practicability is strong. The surface of the insertion rod 10 is provided with a limiting hole 11. During the insertion process, the limiting rod 14 will be stuck in the limiting hole 11, thereby limiting the insertion rod 10 and preventing it from sliding out of the socket 9 and the through hole 701. When disassembly is required, it is only necessary to pull the limiting rod 14 to make the limiting rod 14 slide out of the limiting hole 11. At this time, the insertion rod 10 can be pulled out normally, thereby preventing the insertion rod 10 from falling off during the winding process, causing the reel 6 to lose its limit, thereby improving the stability and practicability of the device.
