Description

Technical Field

[0001] The utility model relates to the technical field of TPU coil processing, in particular to a TPU coil feeding device. Background Art

[0002] TPU, or thermoplastic polyurethane elastomer rubber, is a polymer material formed by the joint reaction and polymerization of diisocyanate molecules, macromolecular polyols, and low molecular polyols.

[0003] According to the disclosed patent CN117429926A, a TPU coil feeding device includes a support, the outer wall of the support is fixedly connected to a first servo motor, the output end of the first servo motor is fixedly connected to two fixed plates, the outer wall of the fixed plate is rotatably connected to the support, and the outer wall of the fixed plate is fixedly connected to a second servo motor distributed in a four-circular axis array; the coil passes through a guide mechanism and is wound onto a winding roller, and the second servo motor is started. The second servo motor will drive the winding roller to wind the coil neatly. The adjustment mechanism can be used to make the winding roller adapt to coils of different widths to ensure that the two ends of the coil will not deviate and tilt outward, thereby increasing the winding range of the winding roller, and the guiding mechanism can guide the coil to avoid wrinkles and overlaps in the coil. The first servo motor is started to rotate the fixed plate to replace different winding rollers. During the process of winding and loading the material, the inventor found that at least the following problems in the prior art have not been solved. The problem of uneven winding of TPU coils, which makes TPU coils prone to wrinkles or staggered extrusion, is solved by adjusting the winding length of the winding roller. During use, in order to ensure that the traditional TPU coil winding roller can be stably placed on the surface of the laminating machine for lamination, the overall length of the winding roller is relatively long, so that the coil can be fully supported and placed. However, when the coil is sleeved on the outside of the winding roller, the overall material of the coil is relatively soft, which causes it to collapse and deform as a whole when placed after winding, making it impossible for the coil to become cylindrical after winding, and causing indentations and wrinkles on the surface of the coil when it is subsequently rolled out for use, thereby affecting the subsequent use of the coil. For this reason, a new technical solution needs to be designed to solve the problem. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a TPU coil feeding device to solve the technical problem that the current coil collapses and deforms as a whole after winding and cannot become a cylindrical shape, resulting in indentations and wrinkles on its surface.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: design a TPU coil feeding device, including a mounting plate, a hollow roller is fixedly installed on the side of the mounting plate, and a fixing rod is slidably installed on the inner side of the hollow roller;

[0006] The outer surface of the fixed rod is fixedly sleeved with a moving block, and the number of the moving blocks is several groups. The inner wall of the hollow roller is fixedly installed with a hollow frame, and the number of the hollow frames is several groups. A push plate is slidably installed on one end of the inner side of each hollow frame close to the fixed rod, and a connecting rod is fixedly installed in the middle of one end of the outer side of each pushing plate close to the fixed rod, and a transmission block is fixedly installed on the side of each connecting rod;

[0008] Preferably, a push spring is movably sleeved on the outer surface of each transmission rod, and two ends of the side edges of the push spring are respectively attached to the push plate and the inner wall of the hollow frame.

[0009] Preferably, an adjusting bolt is rotatably inserted into the side of the fixing rod through a bearing, and the adjusting bolt is threadedly penetrated and screwed into the inside of the side of the hollow roller.

[0010] Preferably, movable rods are longitudinally fixedly installed on both sides of one end of the fixed rod away from the adjusting bolt, and limiting sliding grooves are provided at both ends of the inner side of the hollow roller, and the movable rods are slidably inserted into the limiting sliding grooves.

[0011] Preferably, the hollow roller and the hollow frame are respectively provided with a first movable groove and a second movable groove on the side, and the transmission rod passes through and is slidably inserted into the first movable groove and the second movable groove, each of the hollow frames is provided with sliding grooves on both sides, and each of the push plate side surfaces at both ends are fixedly mounted with sliding blocks, and the sliding blocks are slidably inserted into the sliding grooves.

[0012] Preferably, a protective cushion is fixedly bonded to the outer side wall of each of the fitted arc plates.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model has a driving block with an isosceles trapezoidal cross section sleeved on the outer side of the fixed rod, and a transmission block with a right-angled trapezoidal cross section and a pushing plate that can slide inside the hollow frame are connected through a connecting rod, so that when the fixed rod moves horizontally inside the hollow roller, the driving block can be driven to move horizontally inside the hollow roller synchronously, so that the inclined surface of the driving block contacts the inclined surface of the driving block while moving, thereby causing a driving movement of the driving block, so that the driving blocks located in the four directions outside the driving block can move outward relative to each other, thereby driving the pushing plate to move inside the hollow frame accordingly, and under the transmission action of the transmission rod, a corresponding outward driving force is provided to the hollow roller, so that the bonding arc plate can be stretched outward from the outside of the hollow roller and move relatively, so that the bonding arc plate can be stretched outward from the inner side of the TPU coil sleeved on the outside of the hollow roller, thereby providing support force for the TPU coil when it is rolled and placed, avoiding arbitrary collapse and wrinkling during placement, which affects the subsequent rolling-out quality.

[0015] 2. The utility model provides movable rods at both ends of the outer side of the fixed rod, and opens a limiting slot on the inner wall of the hollow roller. Combined with the guiding and limiting effect of the limiting slot on the movable rod, it can ensure that the fixed rod will not tilt when moving inside the hollow roller. At the same time, combined with the length of the limiting slot, the moving distance of the movable rod and the fixed rod is limited, avoiding excessive movement of the fixed rod, which causes the inclined surface of the abutting block and the inclined surface of the transmission block to separate, affecting the repeatability of the subsequent use of the bonding arc plate position adjustment, thereby ensuring that a stable supporting force is provided when the TPU coil is rolled and placed.

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0026] Example 1: A TPU coil feeding device, see Figures 1 to 4 , including a mounting plate 1, a hollow roller 11 is fixedly installed on the side of the mounting plate 1, a fixed rod 21 is slidably installed on the inner side of the hollow roller 11, a moving block 22 is fixedly sleeved on the outer surface of the fixed rod 21, and the number of the moving blocks 22 is several groups, a hollow frame 23 is fixedly installed on the inner wall of the hollow roller 11, and the number of the hollow frames 23 is several groups, a pushing plate 24 is slidably installed on one end of the inner side of each hollow frame 23 close to the fixed rod 21, a connecting rod 25 is fixedly installed in the middle of one end of the outer side of each pushing plate 24 close to the fixed rod 21, a transmission block 26 is fixedly installed on the side of each connecting rod 25, and a transmission rod 27 is fixedly installed in the middle of one end of each pushing plate 24 away from the fixed rod 21, and the outer wall of the hollow roller 11 is movably fitted and installed It is equipped with bonding arc plates 28, and the number of bonding arc plates 28 is the same as the number of hollow frames 23. The end of the transmission rod 27 away from the pushing plate 24 is fixedly connected to the inner wall of the bonding arc plate 28. The multiple groups of abutment blocks 22 are movably installed inside the hollow roller 11 through the fixing rod 21, and the bonding blocks are movably installed inside the hollow roller 11 under the synchronous transmission action of the connecting rod 25 and the transmission rod 27. Combined with the interaction between the abutment blocks 22 and the transmission blocks 26, the bonding arc plates 28 can be outwardly expanded from the inner side of the TPU coil sleeved on the outside of the hollow roller 11, thereby providing support force for the TPU coil when it is rolled and placed, avoiding arbitrary collapse and wrinkling during placement, which affects the subsequent quality of rolling out and use.

[0027] For details, see Figures 1 to 4 A push spring 29 is movably sleeved on the outer surface of each transmission rod 27, and the two ends of the side of the push spring 29 are respectively attached to the push plate 24 and the inner wall of the hollow frame 23. The reusability of the entire device is ensured by the reverse push action of the push spring 29.

[0028] For further information, see Figures 1 to 4 An adjusting bolt 2 is rotatably inserted into the side of the fixing rod 21 through a bearing, and the adjusting bolt 2 is threadedly penetrated and screwed into the inside of the side of the hollow roller 11. The structural function of the adjusting bolt 2 enables it to provide the fixing rod 21 with a corresponding horizontal push-pull force, thereby facilitating the operator to adjust the moving distance of the fitting arc plate 28.

[0029] It is worth noting that see Figures 1 to 4, movable rods 42 are longitudinally fixedly installed on both sides of the end of the fixed rod 21 away from the adjusting bolt 2, and limiting slots 43 are provided at both ends of the inner side of the hollow roller 11, and the movable rod 42 is slidably inserted into the limiting slots 43. Under the guiding and limiting action of the limiting slots 43 on the movable rod 42, the fixed rod 21 will not move excessively to cause the abutting block 22 and the transmission block 26 to separate, thereby ensuring the stable supporting force provided to the TPU coil when it is rolled and placed.

[0030] It is worth noting that see Figures 1 to 4 The hollow roller 11 and the hollow frame 23 are respectively provided with a first movable groove 3 and a second movable groove 31 on the side, and the transmission rod 27 penetrates and slides into the first movable groove 3 and the second movable groove 31, and each hollow frame 23 is provided with sliding grooves 41 on both sides, and each push plate 24 is fixedly installed with a sliding block 4 on both end surfaces of the side, and the sliding block 4 is slidably inserted into the sliding groove 41. The first movable groove 3 and the second movable groove 31 guide the transmission rod 27 to ensure the rationality of normal movement of the transmission rod 27, and the sliding groove 41 guides the sliding block 4 to ensure that the push plate 24 can only move inside the hollow frame 23 when pushed without tilting or shifting sideways.

[0031] It is worth mentioning that see Figures 1 to 4 The outer side wall of each bonding arc plate 28 is fixedly bonded with a protective pad 5. The structural function of the protective pad 5 ensures that the bonding arc plate 28 will not cause damage to the inner wall of the TPU coil when moving, thereby affecting its subsequent normal use.

[0032] During operation, after the required TPU coil is sleeved on the outside of the hollow roller 11, the adjusting bolt 2 is then screwed, and the movable rod 42 is guided and slid by the limiting slide groove 43 to move horizontally on the side of the hollow roller 11, while driving the fixed rod 21 and the abutting block 22 to move synchronously to the left inside the hollow roller 11, so that the inclined surface of the abutting block 22 contacts the inclined surface of the transmission block 26 while moving horizontally, causing the transmission block 26 to abut, so that the transmission block 26 located in the four directions outside the abutting block 22 can move outward relative to each other, and then, under the guiding and sliding action of the sliding groove 41 on the sliding block 4, the push plate 24 can move outward inside the hollow frame 23, and then, under the guiding and sliding action of the first movable groove 3 and the second movable groove 31, the transmission rod 27 can The pushing force exerted on the surface of the pushing plate 24 is converted into a corresponding outward pushing force on the bonding arc plate 28 located on the outside of the hollow roller 11, so that the bonding arc plate 28 can be stretched outward from the hollow roller 11 and moved horizontally with the fixing rod 21, so that the bonding arc plate 28 can be supported in multiple directions from the inner wall of the TPU coil, so as to avoid the surface collapse of the TPU coil and the existence of wrinkles when it is placed, which affects the subsequent rolling-out and use quality. After use, the adjusting bolt 2 is turned in the reverse direction to drive the fixing rod 21 to move to the right, so that the resistance block 22 loses the resistance force on the transmission block 26. Combined with the reverse pushing action of the pushing spring 29 on the pushing plate 24, the bonding arc plate 28 can be restored to its position and re-bonded to the outside of the hollow roller 11, which is convenient for subsequent reuse.
