Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of automatic unwinding and feeding assembly devices, and specifically to an adjustable automatic unwinding and feeding assembly device. Background Technology
[0002] The automatic unwinding and feeding assembly is a core functional module in automated production lines used for the continuous and precise conveying of rolled materials. It is widely used in industries such as printing, packaging, textiles, electronics manufacturing, metal processing, and lithium battery production. Its main function is to automatically unwind rolled raw materials and convey them to subsequent processing stations with constant tension, precise speed, and position, while achieving unmanned operation and high-efficiency production.
[0003] According to the public announcement (CN222225488U), an automatic unwinding and feeding device is disclosed. This technology discloses that "it includes a base, a vertical plate is fixedly connected to the top of the base, a telescopic cylinder is fixedly installed inside the vertical plate, a lifting platform is fixedly connected to the bottom of the output shaft of the telescopic cylinder, a support plate is fixedly connected to the front of the vertical plate, and a sliding plate is engaged with the top of the support plate. This automatic unwinding and feeding device and other technical solutions have the technical effect of rolling the roll onto the lifting platform during installation, then moving the lifting platform upward with the telescopic cylinder, and when the lifting platform is flush with the support plate, rolling the roll onto the sliding plate, and then pushing the sliding plate backward to install the roll onto the rotating shaft, eliminating the need for manual handling and making operation more labor-saving."
[0004] However, compared with the drum fixing method mentioned above, the traditional limit bolt fixing method is still used. This requires a lot of time cost every time the drum is replaced, which is not conducive to the control of time efficiency of automated production line and increases the reliance on manual operation in the production process.
[0005] To address the aforementioned issues, this application proposes an adjustable automatic unwinding and feeding assembly device. Utility Model Content
[0006] This utility model addresses the technical problems existing in the prior art by providing an adjustable automatic unwinding and feeding assembly device.
[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An adjustable automatic unwinding and feeding assembly device includes a bracket, a motor is fixedly connected to the side end of the bracket, an electric push rod is fixedly connected to the side end of the bracket, a support platform is slidably connected to the surface of the bracket, the output end of the electric push rod is fixedly connected to the support platform, a stop block is fixedly connected to the upper part of the support platform, and a clamping mechanism is provided on the side end of the bracket.
[0008] The clamping mechanism includes a drive gear fixedly connected to the output end of the motor, a driven pinion rotatably connected to the side end of the bracket, the surface of the driven pinion meshing with the drive gear, a driven large gear rotatably connected to the side end of the bracket, the surface of the driven large gear meshing with the drive gear, and a gear ring meshing on the surface of the driven large gear. This arrangement allows the motor to drive the driven pinion and gear ring to rotate via the drive gear.
[0009] A constraint plate is fixedly connected to the side end of the toothed ring. A constraint groove is formed on the surface of the constraint plate. A limit plate is rotatably connected to the side end of the bracket. The surface of the constraint plate is rotatably connected to the limit plate. A limit groove is formed on the surface of the limit plate. A moving block is slidably connected to the constraint plate through the constraint groove. The surface of the moving block is slidably connected to the limit groove. A clamping plate is fixedly connected to the side end of the moving block. By setting up the toothed ring to drive the constraint plate to rotate, the moving block drives the clamping plate to slide along the direction of the limit groove, thereby fixing the drum.
[0010] The bracket is provided with a positioning mechanism on its side. The positioning mechanism includes a lead screw fixedly connected to the side end of the driven pinion. A limit block is fixedly connected to the side end of the lead screw. A movable sleeve is threadedly connected to the surface of the lead screw. A rotating plate is rotatably connected to the surface of the movable sleeve. The mechanism is designed so that the driven pinion rotates, which drives the lead screw to rotate, thereby driving the movable sleeve.
[0011] The rotating plate is fixedly connected to a sliding rod inside, and a rotating block is slidably connected to the surface of the sliding rod. The side end of the rotating block is rotatably connected to the clamping plate. By setting it up, the rotating plate opens to all sides under the constraint of the rotating block while the moving sleeve moves, thereby pushing the drum onto the clamping plate and fixing it on the side to prevent it from slipping.
[0012] The beneficial effects of this utility model are: the electric push rod drives the support platform to transport the roll to the side of the clamping mechanism, and then the motor drives the clamping mechanism to quickly fix the roll, thereby avoiding the time cost wasted by manually fixing the roll.
[0013] As the moving sleeve moves, the rotating plate opens to all sides under the constraint of the rotating block. The rotating plate moves outward and inserts into the inner wall of the drum, and continues to open so that the drum slides along the direction of the rotating plate to the top of the clamping plate. This eliminates the need to manually transport the drum to the clamping plate, and fixes the drum to prevent it from slipping off the side when the side is fully opened. Attached Figure Description

[0025] Reference Figure 1 - Figure 2 An adjustable automatic unwinding and feeding assembly includes a bracket 1, a motor 2 fixedly connected to the side end of the bracket 1, an electric push rod 3 fixedly connected to the side end of the bracket 1, a support platform 4 slidably connected to the surface of the bracket 1, the output end of the electric push rod 3 fixedly connected to the support platform 4, a stop block 5 fixedly connected to the upper part of the support platform 4, and a clamping mechanism 6 provided on the side end of the bracket 1. The roller can be transported to the side end of the clamping mechanism 6 through the support platform 4, and then the clamping mechanism 6 is driven by the motor 2 to quickly fix the roller.
[0026] Reference Figure 1 - Figure 3 The clamping mechanism 6 includes a driving gear 601 fixedly connected to the output end of the motor 2. A driven pinion 602 is rotatably connected to the side end of the bracket 1. The outer circumference of the driven pinion 602 is equal to the inner circumference of the bracket 1 at this location. The surface of the driven pinion 602 meshes with the driving gear 601, and the surface of the driven pinion 602 is adapted to the surface of the driving gear 601. A driven large gear 603 is rotatably connected to the side end of the bracket 1. The outer circumference of the driven large gear 603 is equal to the inner circumference of the bracket 1 at this location. The surface of the driven gear 603 meshes with the driving gear 601, and the surface of the driven gear 603 is adapted to the surface of the driving gear 601. The surface of the driven gear 603 is meshed with the toothed ring 604. The surface of the driven gear 603 is adapted to the surface of the toothed ring 604. The starting motor 2 drives the driving gear 601 to rotate. While the driving gear 601 is rotating, it drives the driven pinion 602 and the driven gear 603 to rotate through the tooth surface. The driven gear 603 then drives the toothed ring 604 to rotate through the tooth surface.
[0027] Reference Figure 1 - Figure 3A constraint plate 605 is fixedly connected to the side end of the toothed ring 604. A constraint groove 606 is provided on the surface of the constraint plate 605. A limit plate 607 is rotatably connected to the side end of the bracket 1. The outer circumference of the limit plate 607 is equal to the inner circumference of the bracket 1 at this location. The surface of the constraint plate 605 is rotatably connected to the limit plate 607. The outer circumference of the constraint plate 605 is equal to the inner circumference of the limit plate 607 at this location. A limit groove 608 is provided on the surface of the limit plate 607. A moving block 609 is slidably connected to the constraint plate 605 through the constraint groove 606. The surface of the moving block 609 is slidably connected to the limit groove 608. A clamping plate 610 is fixedly connected to the side end of the moving block 609. The rotation of the toothed ring 604 drives the constraint plate 605 to rotate, thereby causing the moving block 609 to drive the clamping plate 610 to slide along the direction of the limit groove 608. When the drum is on the clamping plate 610, the spread clamping plate 610 will quickly fix the drum.
[0028] Reference Figure 1 - Figure 4 A positioning mechanism 7 is provided on the side end of the bracket 1. The positioning mechanism 7 includes a lead screw 701 fixedly connected to the side end of the driven pinion 602. A limit block 702 is fixedly connected to the side end of the lead screw 701. A movable sleeve 703 is threadedly connected to the surface of the lead screw 701. The outer wall of the lead screw 701 is adapted to the inner wall of the movable sleeve 703. A rotating plate 704 is rotatably connected to the surface of the movable sleeve 703. The edge of the rotating plate 704 is rounded to allow the drum to slide more smoothly on it. The outer circumference of the movable sleeve 703 at this point is equal to the inner circumference of the rotating plate 704 at this point. A slide rod 705 is fixedly connected inside the rotating plate 704. A rotating block 706 is slidably connected to the surface. The side end of the rotating block 706 is rotatably connected to the clamping plate 610. The outer circumference of the rotating block 706 at this point is equal to the inner circumference of the clamping plate 610 at this point. When the driven pinion 602 rotates, it drives the lead screw 701 to rotate. The sliding rod 705 on the rotating plate 704 can only slide on the rotating block 706. As a result, while the moving sleeve 703 moves, the rotating plate 704 opens to all sides under the constraint of the rotating block 706. The rotating plate 704 moves outward and inserts into the inner wall of the drum. It continues to open so that the drum slides along the direction of the rotating plate 704 to the top of the clamping plate 610. When the side is fully opened, the drum is fixed to prevent it from slipping.
[0029] Working principle:
[0030] The adjustable automatic unwinding and feeding assembly device starts by activating the electric push rod 3, which drives the support table 4 to transport the roll to the side of the clamping mechanism 6. The start motor 2 drives the drive gear 601 to rotate. While the drive gear 601 rotates, it drives the driven pinion 602 and driven gear 603 to rotate through the tooth surface. The driven gear 603 then drives the gear ring 604 to rotate through the tooth surface. The rotation of the gear ring 604 drives the constraint plate 605 to rotate, which in turn causes the moving block 609 to drive the clamping plate 610 to slide along the direction of the limiting groove 608. When the roll is on the clamping plate 610, the spread clamping plate 610 will quickly fix the roll.
[0031] When the driven pinion 602 rotates, it drives the lead screw 701 to rotate. The slide bar 705 on the rotating plate 704 can only slide on the rotating block 706. As a result, while the moving sleeve 703 moves, the rotating plate 704 opens to all sides under the constraint of the rotating block 706. The rotating plate 704 moves outward and inserts into the inner wall of the roll, and continues to open so that the roll slides along the direction of the rotating plate 704 to the top of the clamping plate 610. This eliminates the need to manually transport the roll to the clamping plate 610, and fixes the roll when it is fully opened on the side to prevent it from slipping off the side.
