Description

Technical Field

[0001] This utility model relates to the field of adsorption pad production technology, and in particular to a translational adhesive backing support for adsorption pads. Background Technology

[0002] In the automated adhesive application production line for absorbent pads, the adhesive rolls need to be equipped with a horizontally moving support frame to complete horizontal alignment and continuous feeding. The position of the adhesive discharge is adjusted by the horizontal movement of the frame to match the adhesive application station of the absorbent pads, ensuring the application accuracy and production continuity.

[0003] Existing roll unwinding support frames are divided into single-layer integral sliding type and base-fixed upper-layer correction type. The single-layer integral sliding type has low roll changing efficiency when the motor drives the whole machine to move the station with a large stroke. When it is changed to manual push and pull, the roll changing is fast, but there is no independent correction compensation after resetting, and the alignment accuracy is poor. The base-fixed correction type can only correct the deviation slightly and cannot be moved out as a whole to form a roll changing station. The operating space is insufficient. Simply stacking a manual base and a correction slide table does not reasonably allocate the sliding functions and movement directions of the two layers. The unwinding pull will cause the bottom moving seat to be subjected to axial force, requiring an additional locking mechanism, which reduces the roll changing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a translational adhesive backing support for adsorption pads, so as to solve the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A translational adhesive backing support frame for an absorbent pad includes a linear slide rail, a movable seat, and an unwinding frame. The movable seat is slidably disposed on the linear slide rail and has two stations on the linear slide rail: a first station for unwinding and a second station for changing rolls. The linear slide rail, the movable seat, and the unwinding frame are stacked on top of each other. The unwinding frame is slidably mounted on the movable seat. An unwinding roller is mounted on the unwinding frame. The unwinding direction of the unwinding roller is perpendicular to the moving direction of the movable seat on the linear slide rail. A correction mechanism for driving the unwinding frame to slide is provided between the movable seat and the unwinding frame; The bottom sides of the unwinding frame are fixedly installed with sliding sleeves, and the top sides of the movable seat are fixedly installed with sliding rods. The sliding sleeves and sliding rods are designed with double round tubes nested together.

[0006] As a further description of the above technical solution: the correction mechanism includes a lead screw and a connecting sleeve. The lead screw is rotatably mounted on the movable seat, and the connecting sleeve is fixedly mounted on the bottom of the unwinding frame. The lead screw is threadedly connected to the connecting sleeve. A motor is fixedly mounted on the movable seat. Transmission gears are fixedly mounted on one end of the lead screw and the output end of the motor. Transmission belts are fitted on the two transmission gears.

[0007] As a further description of the above technical solution: the sliding sleeve is slidably engaged with the sliding rod, and the bottom of the sliding sleeve has a groove that is slidably engaged with the sliding rod.

[0008] As a further description of the above technical solution: multiple rollers are fixedly installed at the bottom of the movable seat, and the multiple rollers are arranged on the two linear slide rails.

[0009] This utility model has the following advantages: This utility model adopts a three-layer split sliding structure. The bottom moving seat and linear slide rail undertake the large stroke station switching, and the upper unwinding frame independently realizes small vertical correction and alignment. The station switching and correction action are decoupled. The upper correction mechanism only needs to work with a small stroke, which effectively reduces the motor load and wear of the transmission components. The bottom layer can realize fast station switching whether it is manual or motor driven. The upper layer can compensate for the position deviation caused by the bottom layer's reset. The unwinding roller's unwinding direction is perpendicular to the bottom station switching direction, eliminating the axial component of the roll tension on the moving seat and ensuring stable unwinding without the need for additional locking and limiting components. Combined with the independent sliding guide structure for the upper and lower layers, the movements of the two layers do not interfere with each other, balancing the convenience of roll changing operations with the adhesion accuracy of the adhesive pad.

[0010] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0011] This application provides an overview of various implementations or examples of the technology described in this disclosure, and is not a full disclosure of the entire scope or all features of the disclosed technology. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-5 A sliding adhesive backing support frame for absorbent pads includes a linear slide rail 1, a movable seat 2, and an unwinding frame 3. The movable seat 2 is slidably disposed on the linear slide rail 1 and has two stations on the linear slide rail 1: a first station for unwinding and a second station for changing rolls. In this application, when the unwinding frame is in the unwinding station, it is aligned with the subsequent production machine. The second station is located at the end of the linear slide rail 1 away from the first station, which facilitates changing rolls.

[0016] The unwinding frame 3 is slidably mounted on the movable seat 2. The unwinding frame 3 is equipped with an unwinding roller 4. The unwinding direction of the unwinding roller 4 is perpendicular to the moving direction of the movable seat 2 on the linear slide rail 1. This device, through the cooperation of the linear slide rail 1 and the movable seat 2, allows the movable seat 2 to be pulled by hand. Pulling the movable seat 2 moves the unwinding frame 3, causing the unwinding roller 4 to be moved out, facilitating roll changing. At the same time, since the unwinding direction of the unwinding roller 4 is perpendicular to the moving direction of the movable seat 2 on the linear slide rail 1, the force on the movable seat 2 during unwinding is perpendicular to the direction of the linear slide rail 1. Therefore, the movable seat 2 is not subjected to force along the direction of the linear slide rail 1, so that the movable seat 2 can remain stable without any external force restriction during unwinding. At the same time, unwinding and roll changing can be done by hand.

[0017] As a preferred technical solution in this embodiment, a correction mechanism for driving the unwinding frame 3 to slide is provided between the movable seat 2 and the unwinding frame 3; a sliding sleeve 10 is fixedly installed on both sides of the bottom of the unwinding frame 3, and a sliding rod 11 is fixedly installed on both sides of the top of the movable seat 2. The sliding sleeve 10 and the sliding rod 11 are designed with double round tubes nested together. Since the movable seat 2 is pulled by manpower, the position of the movable seat 2 when returning to its original position cannot be completely consistent. Therefore, this device uses a correction mechanism to correct the unwinding frame 3 to ensure that the support frame is always aligned with the production machine.

[0018] As a preferred embodiment, the correction mechanism includes a lead screw 5 and a connecting sleeve 6. The lead screw 5 is rotatably mounted on the movable base 2, and the connecting sleeve 6 is fixedly mounted on the bottom of the unwinding frame 3. The lead screw 5 is threadedly connected to the connecting sleeve 6. A motor 7 is fixedly mounted on the movable base 2. A transmission gear 8 is fixedly mounted on one end of the lead screw 5 and the output end of the motor 7. A transmission belt 9 is sleeved on the two transmission gears 8. This device drives the transmission gears 8 and the transmission belt 9 to rotate through the motor 7, thereby driving the lead screw 5 to rotate. The lead screw 5 is threadedly driven by the connecting sleeve 6, which drives the unwinding frame 3 to move and perform correction.

[0019] As a preferred technical solution in this embodiment, the sliding sleeve 10 is slidably engaged with the sliding rod 11, and the bottom of the sliding sleeve 10 is slotted to slidably engage with the sliding rod 11; through the sliding engagement of the sliding sleeve 10 and the sliding rod 11, the unwinding frame 3 is assisted to slide smoothly on the moving seat 2.

[0020] As a preferred technical solution of this embodiment, a plurality of rollers 12 are fixedly installed at the bottom of the movable seat 2, and the plurality of rollers 12 are arranged on the two linear slide rails 1; the rollers 12 assist the movable seat 2 in moving on the linear slide rails 1, and the static friction between the rollers 12 and the linear slide rails 1, combined with the fact that the unwinding direction of the unwinding roller 4 is perpendicular to the moving direction of the movable seat 2 on the linear slide rails 1, allows the movable seat 2 to remain stable without any external force restriction when unwinding.

[0021] How the correction mechanism works: After the manual pusher moves the movable seat carrying the adhesive-backed roll material back to the unwinding station along the linear slide rail, there is a positioning deviation when pushing manually. At this time, the correction process is initiated. The support frame is equipped with a laser spotlight for positioning with the subsequent production equipment. The laser spotlight continuously projects positioning laser points towards the adhesive application production equipment behind. The staff observes the laser landing point and operates the controller to issue correction commands.

[0022] The controller drives the motor to operate, and the transmission gear at the output end of the motor drives the lead screw to rotate synchronously via the transmission belt. The lead screw and the connecting sleeve at the bottom of the unwinding frame are threaded together, converting the rotational motion into linear push-pull power, which drives the unwinding frame to slide smoothly and finely laterally along the top slide rod and slide sleeve of the moving seat. During the sliding process, the laser spotlight moves synchronously, and the laser landing point continuously changes. When the laser is accurately aligned with the preset reference point of the production device, the worker uses the controller to cut off the motor power, the lead screw stops rotating, and the unwinding frame is locked in the standard alignment position.

[0023] This mechanism enables small-scale precision correction, compensating for the insufficient accuracy of manual translation and positioning, and ensuring that the unwinding roller's output position is perfectly aligned with the adhesive application station. This significantly shortens the motor drive stroke, improves roll changing efficiency, and ensures the adhesive application accuracy of the adsorption pad.
