Description

Technical Field

[0001] This utility model relates to the field of uncoiler technology, and more specifically, to a strip locking device for an uncoiler. Background Technology

[0002] Uncoiling machines are indispensable equipment in industrial production. They are mainly used to smoothly and accurately unwind coiled metal materials, such as steel strips and aluminum coils, to provide continuous raw materials for subsequent processing steps.

[0003] CN212285373U discloses an uncoiler, relating to the technical field of C-shaped steel processing equipment. It includes a base, a fixed plate fixed to one side of the base along its length, a rotating tube rotatably connected to the middle of the fixed plate, the rotating tube passing through the fixed plate along the length of the base, and a rotating circular plate fixed to the side of the rotating tube away from the fixed plate. Four tensioning plates arranged in a ring are provided on the side of the rotating circular plate away from the fixed plate. A driving assembly is provided on the base to drive each tensioning plate to slide radially on the rotating circular plate. A connecting rod and a connecting assembly for driving the connecting rod are horizontally mounted on the rotating circular plate, sliding along the radial direction of the rotating circular plate. The connecting rod is located on the side opposite to each tensioning plate. A baffle that slides along the length of the connecting rod and a sliding assembly for driving the baffle to move are provided on the side of the connecting rod away from the base. This utility model provides an uncoiler with a simple structure, convenient operation, reduced lateral displacement of the steel strip during traction, and improved steel strip processing efficiency.

[0004] However, this type of uncoiler still has certain limitations in practical applications: although the above-mentioned technical solution can complete the strip uncoiling operation and effectively control lateral deviation, its fixed support structure design has shortcomings. Specifically, the above-mentioned technical solution relies solely on the tension plate to fix and support the strip. However, considering the large weight of the strip itself, this support method is prone to excessive wear on the contact surface between the fixed plate and the rotating tube during the rotation and unfolding process, thereby affecting the service life of the equipment.

A rotating mechanism is provided at the end of the bidirectional lead screw. Auxiliary support mechanisms are fixedly mounted on the lower surfaces of the four corners of the connecting plate, and the outer surfaces of the bottom ends of the four auxiliary support mechanisms are fixedly sleeved to the inner surface of the base.

[0009] It also includes an auxiliary locking and limiting component, the lower surface of which is fixedly installed on the upper surface of the middle part of the base, and the side of the fixing plate is located away from the drive mechanism.

[0010] The rotating mechanism includes a motor and a worm gear. The outer surface of the motor is fixedly installed on the inner surface of the base. A worm is fixedly sleeved on the output end of the motor. The outer surfaces of both ends of the worm are rotatably installed on the inner surface of the base. The worm gear is located below the worm, and its inner surface in the middle is fixedly sleeved on the end of the bidirectional lead screw. The worm and the worm gear mesh with each other.

[0011] The locking assembly includes a rotating tube, a limiting plate, and a mounting plate. The end of the rotating tube is fixedly sleeved to the inner surface of the driving mechanism and rotatably mounted to the inner surface of the fixed plate. A threaded rod is threadedly connected to the inner surface of the rotating tube, and a sleeve is movably sleeved on its outer surface. Four telescopic brackets are provided on the outer surface of the sleeve. Tensioning plates are fixedly mounted on the surfaces of the four telescopic brackets away from the sleeve. The outer surfaces of the ends of the four tensioning plates are slidably mounted to the inner surface of the limiting plate. The middle part of the limiting plate is fixedly sleeved to the outer surface of the rotating tube. The mounting plate is located at the end of the threaded rod away from the rotating tube and is bolted to the end face of the sleeve on its side. The threaded rod is rotatably mounted in the middle of the mounting plate via a bearing.

[0012] The auxiliary locking and limiting assembly includes a limiting groove, the bottom of which is fixedly installed on the upper surface of the base. A sliding plate is slidably installed on the inner surface of the limiting groove. A rotary joint is provided on the upper surface of the sliding plate. The two ends of the rotary joint are respectively fixedly installed on the upper surface of the sliding plate and the side of the bottom end of the connecting rod.

The outer surface of the bottom end of the electric telescopic rod is movably sleeved with the inner surface of the end of the threaded rod.

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

[0014] In the above scheme, by setting up a lower support component, after the strip steel is locked, the operator controls the motor to start, and the worm gear fixedly connected to its output end rotates, driving the meshing worm wheel to rotate, which in turn drives the installed bidirectional lead screw to rotate inside the platform. At this time, as the bidirectional lead screw rotates, the bottom ends of the two three-fold rods threaded at both ends slide against the inner surface of the platform and move closer to each other, causing the three-fold rods to gradually extend, thereby pushing the connecting plate installed at the top to move upward until the outer edges of the two rotating rollers set on both sides of the top of the connecting plate are in contact with the surface of the strip steel, thus achieving the effect of supporting the strip steel. Furthermore, when the strip steel is unfolded, the rotation of the rotating rollers reduces frictional damage to the strip steel, further assists in setting up support for the strip steel, reduces the pressure intensity at the junction of the rotating tube and the fixed plate, and extends the service life of the equipment.

[0015] In the above scheme, by setting an auxiliary locking and limiting component, when locking the strip steel with the help of the locking component, the operator can first control the vertical rotation of the connecting rod, then connect the collar fixed at its top with the end of the threaded rod away from the fixed plate, and control the extension of the electric telescopic rod so that its end is inserted into the inside of the threaded rod for limiting. At the same time, control the telescopic rod used to connect the buckle limiting mechanism to retract, so that the buckle limiting mechanism is inserted into the corresponding groove at the bottom of the connecting rod along the inside of the sliding plate, thus completing the limiting of the connecting rod. Afterwards, the operator drives the rotating tube to rotate through the drive mechanism. Under the limiting action of the threaded rod by the auxiliary locking and limiting component, the threaded rod gradually moves into the inside of the rotating tube, thereby realizing the locking of the strip steel by the locking component and improving the labor-saving effect of the device.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides a strip locking device for an uncoiler, including...

[0024] A base 1 has a fixed plate 2 fixedly installed on the upper surface of the middle part of the base 1. A drive mechanism 6 is provided on the side of the fixed plate 2. A side guide component 3 is fixedly installed on the side edge of the top of the fixed plate 2. A locking component 5 is rotatably installed on the inner surface of the top of the fixed plate 2, and the outer surface of the end of the locking component 5 is fixedly sleeved inside the drive mechanism 6.

[0025] By setting the side guide assembly 3, after the strip is locked, its end passes through the gap of the side guide assembly 3 first, and the spacing of the side guide assembly 3 is adjusted so that the roller that is in contact with the surface of the strip is in contact with the strip, thereby limiting the height of the output end of the strip and reducing the friction damage caused by its falling to the ground or the equipment.

[0026] The lower support assembly 4 is located at the bottom of the fixed plate 2 near the locking assembly 5. The lower support assembly 4 includes a connecting plate 40 and a bidirectional lead screw 43. Rotating rollers 41 are rotatably installed on the upper surfaces of both sides of the top of the connecting plate 40. Two three-fold rods 44 are fixedly connected to the lower surface of the middle part of the connecting plate 40. The two three-fold rods 44 are symmetrically arranged. The inner surfaces of the bottom ends of the two three-fold rods 44 are threadedly connected to the outer surfaces of the two ends of the bidirectional lead screw 43, and the outer surfaces of the bottom ends are slidably installed with the inner surface of the base 1. The outer surfaces of the two ends and the middle part of the bidirectional lead screw 43 are rotatably installed with the inner surface of the base 1. A rotating mechanism 42 is provided at the end of the bidirectional lead screw 43. Auxiliary support mechanisms 45 are fixedly installed on the lower surfaces of the four corners of the connecting plate 40, and the outer surfaces of the bottom ends of the four auxiliary support mechanisms 45 are fixedly sleeved with the inner surface of the base 1.

[0027] It also includes an auxiliary locking and limiting component 7, the lower surface of which is fixedly installed on the upper surface of the middle part of the base 1, and the side of the fixing plate 2 away from the drive mechanism 6 is provided.

[0028] The rotating mechanism 42 includes a motor 420 and a worm gear 422. The outer surface of the motor 420 is fixedly installed on the inner surface of the base 1. The output end of the motor 420 is fixedly sleeved with a worm 421. The outer surfaces of both ends of the worm 421 are rotatably installed on the inner surface of the base 1. The worm gear 422 is located below the worm 421, and its middle inner surface is fixedly sleeved with the end of the bidirectional lead screw 43. The worm 421 and the worm gear 422 mesh with each other.

[0029] By setting up a rotating mechanism 42, the diameter of the strip gradually decreases as it unfolds. At this time, the operator can adjust the rotation speed of the motor 420 so that the output end of the motor drives the bidirectional lead screw 43 through the worm gear 421 and other structures to rotate, thereby causing the three-fold rod 44 to push the connecting plate 40 to change its rising height, thus achieving comprehensive support during the unfolding process of the strip.

[0030] The locking assembly 5 includes a rotating tube 50, a limiting disc 53, and a mounting plate 56. The end of the rotating tube 50 is fixedly sleeved with the inner surface of the drive mechanism 6 and rotatably installed with the inner surface of the fixing plate 2. The inner surface of the rotating tube 50 is threadedly connected with a threaded rod 55, and a sleeve 51 is movably sleeved on the outside. Four telescopic brackets 52 are provided on the outer surface of the sleeve 51. Tensioning plates 54 are fixedly installed on the surfaces of the four telescopic brackets 52 away from the sleeve 51. The outer surfaces of the ends of the four tensioning plates 54 are slidably installed with the inner surface of the limiting disc 53. The middle part of the limiting disc 53 is fixedly sleeved with the outer surface of the rotating tube 50. The mounting plate 56 is located at the end of the threaded rod 55 away from the rotating tube 50, and its side is bolted to the end face of the sleeve 51. The threaded rod 55 is rotatably installed in the middle of the mounting plate 56 through a bearing.

[0031] The auxiliary locking and limiting assembly 7 includes a limiting groove 70. The bottom of the limiting groove 70 is fixedly installed on the upper surface of the base 1. A sliding plate 71 is slidably installed on the inner surface of the limiting groove 70. A rotary joint 72 is provided on the upper surface of the sliding plate 71. The two ends of the rotary joint 72 are respectively fixedly installed on the upper surface of the sliding plate 71 and the side of the bottom end of the connecting rod 74. A snap-fit ​​limiting mechanism 73 is provided in the middle of the end of the sliding plate 71 away from the rotary joint 72. A collar 75 is fixedly installed on the top end of the connecting rod 74. The inner surface of the collar 75 is movably sleeved with the outer surface of the end of the threaded rod 55 away from the rotating tube 50. An electric telescopic rod 76 is fixedly installed on the top of the collar 75. The outer surface of the bottom end of the electric telescopic rod 76 is movably sleeved with the inner surface of the end of the threaded rod 55.

[0032] By setting the auxiliary locking and limiting component 7, when locking the strip steel with the locking component 5, the operator can first control the vertical rotation of the connecting rod 74, then engage the collar 75 fixed at its top with the end of the threaded rod 55 away from the fixed plate 2, and control the extension of the electric telescopic rod 76 so that its end is inserted into the inside of the threaded rod 55 for limiting. At the same time, control the telescopic rod used to connect the buckle limiting mechanism 73 to retract, so that the buckle limiting mechanism 73 is inserted into the corresponding slot at the bottom of the connecting rod 74 along the inside of the sliding plate 71, thus limiting the connecting rod 74. After that, the operator drives the rotating tube 50 to rotate through the drive mechanism 6. Under the limiting action of the auxiliary locking and limiting component 7 on the threaded rod 55, the threaded rod 55 gradually moves into the inside of the rotating tube 50, thereby realizing the locking of the strip steel by the locking component 5 and improving the labor-saving effect of the device.

[0033] The working process of this utility model is as follows:

[0034] When it is necessary to uncoil the strip, it is passed through the outside of the shrinking locking assembly 5. Then, the threaded rod 55 is rotated, and the threaded rod 55 moves along the inner surface of the threaded rotating tube 50, which drives the sleeve 51 connected by the mounting plate 56 to slide along the outer surface of the rotating tube 50. As the threaded rod 55 drives the sleeve 51 to gradually approach the fixed plate 2, the telescopic frame 52 and the tension plate 54 outside are restricted by the limit plate 53 and gradually expand outward until the outer edge of the tension plate 54 is in contact with the inside of the strip, thereby completing the locking and fixing of the strip, which is convenient for subsequent unfolding.

[0035] After the strip is locked, the operator starts the motor 420, which rotates the worm gear 421 fixedly sleeved at its output end, driving the meshing worm wheel 422 to rotate, which in turn drives the installed bidirectional lead screw 43 to rotate inside the base 1. At this time, as the bidirectional lead screw 43 rotates, the bottom ends of the two three-fold rods 44 threaded at both ends slide against the inner surface of the base 1 and move closer to each other, causing the three-fold rods 44 to gradually extend, thereby pushing the connecting plate 40 installed at the top to move upward until the outer edges of the two rotating rollers 41 set on both sides of the top of the connecting plate 40 are in contact with the surface of the strip, thus achieving the effect of supporting the strip. Furthermore, when the strip is unfolded, the rotation of the rotating rollers 41 reduces frictional damage to the strip, further assists in supporting the strip, reduces the pressure intensity at the junction of the rotating tube 50 and the fixed plate 2, and extends the service life of the equipment.
