Description

Technical Field

[0001] This utility model relates to an improved invention of packaging bag processing equipment, and more particularly to a composite mechanism of packaging bag processing equipment. Background Technology

[0002] One side of the film roll is glued, and the other side overlaps the glued side, bonding them together to form a bag blank. At the bonding point, the two sides of the film roll overlap vertically, forming the upper and lower layers, respectively, and the bonding area is then rolled and shaped by pressure rollers. Existing pressure rollers can only be adjusted laterally on the frame according to the glued area. However, due to processing, the film roll's lateral thickness is not uniform. If the gap between the pressure roller and the lower support roller is constant, the glue on the thicker side of the film will migrate to the thinner side during rolling, resulting in uneven glue thickness at the sealing point. Thicker glue has higher hardness, which affects the opening of the formed bag, leading to subsequent packaging failures. Furthermore, thinner films experience less pressure, while thicker films experience more pressure; this uneven pressure causes wrinkles, increasing the scrap rate. Summary of the Invention

[0003] In view of the technical problems existing in the background art, the technical problem solved by this utility model is to provide a feeding mechanism for a general-purpose battery packaging machine, which is easy to operate and highly practical.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the composite mechanism of the packaging bag processing equipment is characterized in that: it includes a pressure roller, which is rotatably mounted on a left side plate and a right side plate. The left side plate and the right side plate are vertically slidably mounted on a mounting plate via a left guide rail and a right guide rail, respectively. The left guide rail and the right guide rail are vertically arranged. The mounting plate is equipped with a first adjusting component for adjusting the height difference between the left side plate and the right side plate, and a first driving component for driving the left side plate and the right side plate to rise and fall.

[0005] This invention can adjust the angle between the pressure roller and the horizontal plane according to the thickness of the material. If the material is thinner on the left side than on the right side, the right side plate moves up relative to the left side plate, and the left side of the pressure roller tilts downward, so that the film is subjected to uniform force, maintains flat output, and the glue thickness of the sealing part is consistent and the hardness is moderate, which is conducive to the smooth operation of the packaging equipment.

[0006] Preferably, the right side plate is connected to a horizontal plate, and the first driving member is connected to the horizontal plate;

[0007] The left side plate is connected to a mounting block, and the mounting block is movably connected to the horizontal plate.

[0008] The first adjusting component includes an adjusting screw, which is rotatably mounted on the mounting plate and moves up and down relative to the mounting plate. The adjusting screw presses against the horizontal plate and controls the height distance between the horizontal plate and the mounting block. By adjusting the distance between the horizontal plate and the mounting block, the relative height positions of the left and right side plates change, ultimately adjusting the angle between the pressure roller and the horizontal plane, thus solving the problem of uneven material thickness.

[0009] Preferably, the first adjusting component further includes a first spring and a first bolt. One end of the first bolt passes through the first spring and the horizontal plate in sequence and is threadedly connected to the mounting block, or one end of the first bolt passes through the first spring and the mounting block in sequence and is threadedly connected to the horizontal plate. The elastic force of the first spring causes the mounting block and the horizontal plate to move closer together, while the adjusting screw overcomes the elastic force of the first spring, presses against the horizontal plate, and adjusts the distance between the horizontal plate and the mounting block. The adjustment is convenient, and the horizontal plate and the mounting block maintain tension and are balanced in force.

[0010] Preferably, the lower end of the adjusting screw passes through the mounting block and presses against the horizontal plate, while the upper end of the adjusting screw is threadedly connected to a nut. The mounting plate is provided with a limiting component to restrict the vertical movement of the nut, and the circumferential surface of the nut is provided with transmission teeth that mesh with a worm gear. Rotation of the worm gear drives the nut to rotate, which in turn drives the adjusting screw to rise and fall, facilitating operation by the worker.

[0011] Preferably, the mounting plate is rotatably mounted on the movable plate via a rotating shaft, and the mounting plate is connected to a second adjusting component for adjusting its vertical angle. When the upper tension of the sealing part is low, it is prone to slipping outwards during the roller pressing and traction process. By adjusting the front and rear tilt angle of the pressure roller through the second adjusting component, the force exerted by the pressure roller on the upper layer is biased inwards, offsetting the force that causes outward slippage due to low tension, thus aligning the upper and lower layers of the sealing part and ensuring proper positioning.

[0012] Preferably, the second adjusting component includes a second bolt and a second spring, with one end of the second bolt passing through the mounting plate and the spring in sequence and threadedly connected to the movable plate. The angle of the mounting plate can be adjusted by rotating the second bolt, making adjustment convenient and quick.

[0013] Preferably, the mounting plate is provided with a first connecting arm, which is connected to a rotating shaft; the movable plate is provided with a second connecting arm, which is rotatably connected to the rotating shaft, and the first connecting arm and the second connecting arm are arranged vertically and axially fixed relative to each other.

[0014] Preferably, both the first and second connecting arms have two sets, with the first and second connecting walls of each set in contact, and the two first connecting walls being between the two second connecting walls or the two second connecting walls being between the two first connecting walls. This design is simple in structure and convenient to install and adjust.

[0015] Preferably, the movable plate is slidably mounted on the crossbeam, and the movable plate is connected to a third adjusting component for adjusting its lateral position on the frame;

[0016] The third adjusting component includes a transverse screw, which is rotatably mounted on the frame. A third connecting arm is provided on the back of the movable plate, and the transverse screw is threadedly connected to the third connecting arm.

[0017] The crossbeam is equipped with a linear guide rail, and the movable plate is equipped with a slider, which is slidably mounted on the linear guide rail.

[0018] Depending on the sealing position, the lateral position of the pressure roller on the frame is adjusted by the third adjusting component to meet the processing needs of bags of different specifications.

[0019] Preferably, the pressure roller is connected to a motor, which is mounted on the right side plate. Attached Figure Description

[0025] The following description, in conjunction with the accompanying drawings, details the embodiments and working principles of this utility model. In the figures, the X-axis represents the horizontal direction (left-right); the Y-axis represents the vertical direction (front-back); and the Z-axis represents the vertical direction (up-down).

[0026] The composite mechanism of this packaging bag processing equipment includes a pressure roller 1, which is connected to a motor 26. The motor drives the pressure roller 1 to rotate. The pressure roller 1 is rotatably mounted on a left side plate 2 and a right side plate 3. The left side plate 2 and the right side plate 3 are vertically slidably mounted on a mounting plate 11 via left and right guide rails 22, respectively. The left and right guide rails 22 are vertically arranged. In the figure, the left and right guide rails 22 are respectively mounted on the left side plate 2 and the right side plate 3. The mounting plate 11 is provided with a left slide block and a right slide block, which are slidably disposed with the left and right guide rails 22, respectively. The mounting plate 11 is equipped with a first adjusting component for adjusting the height difference between the left side plate 2 and the right side plate 3, and a first driving component 10 for driving the left side plate 2 and the right side plate 3 to rise and fall. In the non-working state, the first driving component 10 drives the left side plate 2 and the right side plate 3 to move upward along the left guide rail and the right guide rail 22 respectively, that is, drives the pressure roller 1 to move upward and away from the lower roller. In operation, the first driving component 10 drives the pressure roller 1 to move downward. The pressure roller 1 rotates and cooperates with the lower roller to pull and roll the roll material, and the upper and lower layers of the adhesive part of the roll material are bonded together. The first adjusting component adjusts the height difference between the left side plate 2 and the right side plate 3, that is, adjusts the angle between the pressure roller 1 and the horizontal plane and the lower roller. Usually, the lower roller is set horizontally. If the thickness of the sealed part of the roll material is consistent, the pressure roller 1 is parallel to the vertical direction of the lower roller. If the left side of the sealed part of the roll material is thinner than the right side, the left side of the pressure roller 1 is lower than the right side. If the right side of the sealed part of the roll material is thinner than the left side, the right side of the pressure roller 1 is lower than the left side, so that the thickness of the adhesive in the sealed part is consistent and moderate, and the roll material is subjected to the same pressure. The bonded roll material is flat and wrinkle-free.

[0027] The right side plate 3 is connected to a horizontal plate 7. The first driving component 10 is connected to the horizontal plate 7. The motor is mounted on the right side plate 3. The left side plate 2 is connected to a mounting block 4. The mounting block 4 is movably connected to the horizontal plate 7. The first driving component 10 driving the horizontal plate 7 to rise and fall is equivalent to the first driving component 10 driving the left side plate 2 and the right side plate 3 to rise and fall. At the same time, the distance between the mounting block 4 and the horizontal plate 7 can be adjusted by the first adjusting component. The first adjusting component includes an adjusting screw 8, a first spring 5, and a first bolt 6. The adjusting screw 8 is rotatably mounted on the mounting plate 11 and rises and falls relative to the mounting plate 11. The adjusting screw 8 presses against the horizontal plate 7 and controls the height distance between the horizontal plate 7 and the mounting block 4. In the figure, the upper end of the first bolt 6 passes through the first spring 5 and the horizontal plate 7 in sequence and is threadedly connected to the mounting block 4. The first bolt 6 connects the mounting block 4 and the horizontal plate 7. The elastic force of the first spring 5 causes the mounting block 4 and the horizontal plate 7 to move closer to each other. The adjusting screw 8 overcomes the elastic force of the first spring 5 and presses against the horizontal plate 7. The adjusting screw 8 moves down and presses against the horizontal plate 7. Due to the restriction of the first driving component 10, the left side plate 2 moves up relative to the right side plate 3, that is, the left end of the pressure roller 1 moves up. If the adjusting screw 8 moves up, the distance between the mounting block 4 and the horizontal plate 7 becomes smaller under the action of the elastic force of the first spring 5. The left side plate 2 moves down relative to the right side plate 3, and the left end of the pressure roller 1 moves down. In this way, the angle between the pressure roller 1 and the horizontal plane and the lower roller is adjusted. For ease of operation, the lower end of the adjusting screw 8 passes through the mounting block 4 and presses against the horizontal plate 7. The upper end of the adjusting screw 8 is threadedly connected to a nut 17. The mounting plate 11 is provided with a limiting member 16 to restrict the vertical movement of the nut 17. The circumferential surface of the nut 17 is provided with transmission teeth, which mesh with the worm gear 9. The adjusting screw 8 is set vertically, but its upper end is too high, making it inconvenient for operators to operate. The worm gear 9 is set horizontally, which makes it easier for operators to operate. The rotation of the worm gear 9 drives the nut 17 to rotate, and the rotation of the nut 17 drives the adjusting screw 8 to rise and fall, thereby adjusting the relative height position of the left side plate 2 and the right side plate 3.

[0028] The mounting plate 11 is rotatably mounted on the movable plate 12 via a rotating shaft 13. The mounting plate 11 is connected to a second adjusting component that adjusts its vertical angle. There is a tension difference between the upper and lower layers of the roll sealing section. Usually, the lower layer has a higher tension and the upper layer has a lower tension, making the upper layer relatively loose. If the pressure roller 1 is parallel to the lower roller in the horizontal direction, the upper layer will deviate during compound traction, for example, the upper layer will shift outward. This utility model can use the second adjusting component to make the mounting plate 11 rotate vertically relative to the movable plate 12, that is, the pressure roller 1 swings forward or backward relative to the lower roller. The force of the pressure roller 1 acting on the upper layer is biased inward, which cancels out the force of the upper layer shifting outward due to the lower tension, so that the upper and lower layers of the sealing section are aligned and in the correct position. The second adjusting component includes a second bolt 15 and a second spring 14. One end of the second bolt 15 passes sequentially through the mounting plate 11 and the spring, and is threadedly connected to the moving plate 12. When the second bolt 15 rotates clockwise, it reduces the distance between the right side of the mounting plate 11 and the moving plate 12. That is, when the mounting plate 11 rotates counterclockwise, the left end of the pressure roller 1 swings backward and the right end forward. Conversely, when the second bolt 15 rotates counterclockwise, it reduces the distance between the right side of the mounting plate 11 and the moving plate 12, causing the left end of the pressure roller 1 to swing forward and the right end backward. Adjustment is convenient and quick. The mounting plate 11 is provided with a first connecting arm 19, which is connected to the rotating shaft 13. The moving plate 12 is provided with a second connecting arm 20, which is rotatably connected to the rotating shaft 13. The first connecting arm 19 and the second connecting arm are vertically arranged and axially fixed relative to each other. (See attached document) Figure 4 The first connecting arm 19 and the second connecting arm 20 are each provided with two sets, with the first connecting wall and the second connecting wall of each set in contact, and the two first connecting walls between the two second connecting walls. The structure is simple and easy to install and adjust.

[0029] The movable plate 12 is slidably mounted on the crossbeam 23, and is connected to a third adjusting component that adjusts its lateral position on the frame 21. The third adjusting component includes a transverse screw 25, which is rotatably mounted on the frame 21. A third connecting arm 18 is provided on the back of the movable plate 12, and the transverse screw 25 is threadedly connected to the third connecting arm 18. A linear guide rail 24 is provided on the crossbeam 23, and a slider is provided on the movable plate 12, which is slidably mounted on the linear guide rail 24. Rotating the transverse screw 25 causes the third connecting arm 18 to move laterally along the linear guide rail 24 on the crossbeam 23, i.e., the lateral position of the pressure roller 1 on the frame 21 is adjusted by the third adjusting component according to the sealing position to meet the processing needs of different specifications of bag bodies or bag blanks.

[0030] The pressure roller 1 of this utility model can adjust its lateral position on the frame 21, its angle with the horizontal plane, and its vertical angle with the lower roller. This satisfies the processing requirements of bag bodies and bag blanks of different specifications, as well as the processing requirements of uneven roll thickness, thereby improving the quality of bag blanks and bags.
