Description

Technical Field

[0001] The present invention relates to the technical field of two-in-one bag discharging devices, and in particular to a two-in-one bag discharging device. Background Art

[0002] In public places in hospitals, users often need to use bags to carry personal items, medical waste or other items that are temporarily needed. The traditional way of collecting bags is usually through manual distribution or simple bag racks, which is not only inefficient, but also may result in bag waste or inconvenience in collection. At the same time, in public areas, the convenience and hygiene of the equipment are key considerations, so a device that can automatically, conveniently and safely distribute bags is needed.

[0003] The existing Chinese patent with publication number CN116749589B includes a frame; a discharge device, in which a discharge motor drives a discharge roller to rotate so that the material can be separated; a clamping device, which is used to clamp and transport the material; the upper clamping roller rotates counterclockwise, and the lower clamping roller rotates clockwise; a cutting device, in which a cutting motor drives a cutting motor to rotate so that the cutter reciprocates in the vertical direction; a clamping device, in which a clamping motor controls the rotation of a rotating part so that the clamping plate reciprocates in the vertical direction; a clamping device, in which a slider can make reciprocating linear motion on a fixed slide rail, and a clamping claw is used to clamp the material.

[0004] When the above-mentioned device is in use, it is electrically connected to each key component through the control device, so that the cutting and transportation process can be monitored in real time, and dynamic adjustments can be made as needed, so that the device can respond to production changes and needs in a timely manner, thereby improving production efficiency and quality stability. However, in actual use, most of the existing bag discharging devices are equipped with single-roll bags. When a single-roll bag is used up, it needs to be replaced, which will cause the entire production line to stagnate, affecting production efficiency and economic benefits. Therefore, it is difficult to automatically switch between two rolls of bags to perform bag discharging work separately.

[0012] Preferably, the opposite sides of the two support plates are rotatably connected to the first pulleys via a pin shaft, and each of the first pulleys is fixedly connected to a columnar block that drives the L-shaped rod to move up and down and reciprocate, and the outer contours of the two columnar blocks are provided with a limit frame, and the bottom end of the L-shaped rod on each side is fixedly connected to the limit frame on the adjacent side.

[0016] Preferably, the rectangular frame is fixedly connected to fixed frames at positions corresponding to the transmission rollers on the upper and lower sides away from one end of the swing rod, and each of the fixed frames is transmission-connected to relatively rotating discharge rollers and auxiliary rollers at symmetrical positions on both sides of the inner wall, and the discharge rollers are driven to rotate by a motor.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. When the sleeve block moves to the limit distance of the reciprocating screw away from one end of the fixed plate, and the guide block at the end of the moving rod away from the sleeve block contacts the transmission rod and pushes the transmission rod to rotate in the direction close to the reciprocating screw, so that the rotating rod drives the transmission gear to move through the arc shell under the action of the arc shell and meshes with the connecting gear close to the reciprocating screw. At the same time, the connecting gear drives the transmission roller close to the reciprocating screw to rotate to transport the bags on the unloading roller on the adjacent side. At this time, the transmission roller away from the reciprocating screw remains stationary. When the sleeve block moves to the limit distance of the reciprocating screw close to one end of the moving rod, and the guide block at the end of the moving rod close to the sleeve block moves to contact the transmission rod and push the transmission rod toward the far By rotating in the direction away from the reciprocating screw, the rotating rod can drive the transmission gear to move through the arc shell under the action of the arc shell and engage with the connecting gear on the side away from the reciprocating screw, and then the connecting gear can drive the transmission roller on the side away from the reciprocating screw to rotate to convey the bags on the adjacent unloading roller. At this time, the transmission roller close to one end of the reciprocating screw remains stationary, realizing automatic switching to convey the bags on the two unloading rollers respectively. When one roll of unloading roller is used up, it can automatically switch to the other roll of unloading roller for conveying operations, providing personnel with time to replace the unloading roller, ensuring the continuity of production and the stability of product supply, and avoiding long-term shutdown of the production line and affecting production efficiency.

[0018] 2. Through the second pulley arranged on the transmission roller, the second pulley can synchronously rotate along with the transmission roller on a fixed axis, and through the first pulley arranged on the support plate and the transmission belt arranged on the first pulley and the second pulley, the fixed axis rotation is performed along with the second pulley, so that the transmission belt drives the first pulley to rotate synchronously on the support plate on a fixed axis under the action of the second pulley, through the cylindrical shell on the rectangular frame and the L-shaped rod arranged on the cylindrical shell, the cylindrical shell fixes the L-shaped rod on the rectangular frame, through the cylindrical block arranged on the first pulley and the limit frame arranged on the cylindrical block, the cylindrical block penetrates to the inner wall of the limit frame and is movably connected, and the L-shaped rod is fixed to the limit frame The fixed connection is accompanied by the fixed axis rotation of the first pulley, so that the limit frame pulls the L-shaped rod to perform up and down reciprocating movement on the cylindrical shell under the action of the column block, and through the cutting blade arranged on the L-shaped rod and the cutting groove opened on the rectangular frame, when the L-shaped rod drives the cutting blade to move in the vertical direction close to the rectangular frame, the cutting blade can be moved to the inner wall of the cutting groove to cut the bag on the rectangular frame, and the heating plate arranged on the cutting blade, along with the cutting blade moving to the inner wall of the cutting groove to cut the bag, makes the heating plate squeeze and heat one end of the bag after cutting, so that the two layers of material at one end of the bag can be fused together, thereby realizing the sealing operation on one end of the bag.

[0019] 3. As the L-shaped rod moves up and down and reciprocatingly, the piston plate can move up and down and reciprocatingly on the inner wall of the cylindrical shell under the action of the L-shaped rod. When the piston plate moves toward the end away from the connecting pipe, the internal air pressure of the cylindrical shell close to the end of the connecting pipe is negative pressure, so that the connecting pipe can suck external air into the inner wall of the cylindrical shell. When the piston plate moves toward the end close to the connecting pipe, the air pressure on the inner wall of the cylindrical shell close to the end of the connecting pipe is positive pressure, so that the connecting pipe can discharge the air inside the cylindrical shell, and the piston plate can blow air on the surface of the conveying bag. The outlet direction of the connecting pipe away from the end of the cylindrical shell is the same as the conveying direction, which improves the movement speed of the conveying end of the bag and ensures the flatness of the bag surface.

[0020] Fourth, as the limit frame moves up and down and back and forth, the adjusting rod can push the swing rod to swing back and forth on the rectangular frame under the action of the limit frame, and the columnar rod arranged on the swing rod contacts the bottom of the bag. As the swing rod swings back and forth, the swing rod can drive the columnar rod to beat the bag back and forth, thereby avoiding wrinkles on the bag surface due to stacking and further ensuring the flatness of the bag surface.

[0021] The coordinated use of the above-mentioned structure solves the problem that in actual use of the existing devices, most of the bag discharging devices are equipped with single-roll bags. When the single-roll bag is used up, it needs to be replaced, which will cause the entire production line to stagnate, affecting production efficiency and economic benefits. Therefore, it is difficult to automatically switch between two rolls of bags to carry out bag discharging work separately. BRIEF DESCRIPTION OF THE DRAWINGS
