A feeding mechanism for bubble wrap

Abstract

This utility model relates to a bubble bag feeding mechanism in the field of bubble bag feeding technology. When the conveying direction of the bubble bag changes, to prevent one side of the bubble bag from becoming loose, the knob on the loose side is rotated, causing the rotating shaft to drive the lead screw to rotate. The lead screw nut, in conjunction with the lead screw, drives the slider to move upward. The connecting seat three drives one side of the roller to move upward, causing the roller to gradually tilt. One side of the roller is higher than the other side, and the raised side of the roller gradually tightens the loose bubble bag, making the bubble bag adhere to the surface of the roller. This ensures stable conveying of the bubble bag when the conveying direction changes, and prevents wrinkles from forming between the conveying roller one and conveying roller two, thus protecting the bubble bag and preventing the bubbles on the bubble bag from bursting under pressure.

Description

Technical Field

[0001] This utility model relates to the field of bubble bag feeding technology, and in particular to a bubble bag feeding mechanism. Background Technology

[0002] Bubble bags are mainly used for cushioning packaging of electronic products, plastic products, metal products, ceramic products, glass products, and other products that require cushioning protection during logistics and transportation. During the production and processing of bubble bags, it is often necessary to transport them.

[0003] For example, Chinese patent application CN202421028667.8 discloses a bubble bag feeding mechanism. Specifically, in use, the end of the swing base is hinged to a fixed frame via a hinge lug, allowing manual adjustment of the swing base's position. This enables the support side plate to swing. A second motor drives the bubble bag take-up roller to rotate, automatically feeding the bubble bags. A limiting port limits the output bubble bags. A first motor drives the upper feeding roller to rotate, which in turn drives the lower feeding roller via a transmission pulley. Both the upper and lower feeding rollers engage with the bubbles on the outside of the bubble bag through feeding teeth, assisting in stable feeding. A clamp facilitates the tightening and fixing of the first motor. However, this mechanism presents the following technical problems:

[0004] When adjusting the conveying direction of the bubble bag, the swing seat swings, and the supporting side plate drives the upper and lower feeding rollers to rotate. Although the feeding direction changes, the bubble bag is prone to deviation during the conveying process. This causes one side of the bubble bag to become loose when the upper and lower feeding rollers feed the bubble bag. The loosened bubbles are squeezed and wrinkled between the upper and lower feeding rollers. The squeezed bubble bag is prone to bursting, thus reducing the effectiveness of the bubble bag. It can be seen that the above structure is prone to damaging the bubble bag when conveying it with a changed conveying direction. Utility Model Content

[0005] To address the problem mentioned in the background art that bubble bags are easily damaged during transport when the conveying direction is changed, this utility model provides the following technical solution:

[0006] A feeding mechanism for bubble bags includes a feeding table installed on the upper end of a shelf;

[0007] The upper and lower ends of the right side of the feeding platform are equipped with conveyor roller one and conveyor roller two for conveying bubble bags.

[0008] The left side of the feeding platform is equipped with a rotating roller for tensioning the bubble bag, and two limiting structures for limiting the rotation roller are symmetrically installed on the left side of the feeding platform.

[0009] The limiting structure includes a slider for controlling the angle change of the roller.

[0010] Furthermore, the upper end of the feeding platform is equipped with side plate 1 and side plate 2 for limiting the movement of conveyor roller 1 and conveyor roller 2, and the front end of side plate 2 is equipped with a motor for controlling the rotation of conveyor roller 1.

[0011] Furthermore, the rotating roller includes a roller body, a plurality of annular grooves are equally spaced in the middle of the roller body, an insertion hole is provided in the middle of the front end of the roller body, and a protective sleeve to prevent the bubble bag from shifting is installed in the annular groove.

[0012] Furthermore, a connecting seat is installed at the rear end of the roller body, and a connecting block is installed on the side of the connecting seat near the roller body, and the connecting block is movably installed at the rear end of the roller body.

[0013] Furthermore, a connecting seat two is installed at the front end of the roller body, and a sliding rod for sliding in the insertion hole is installed at one end of the connecting seat two near the roller body.

[0014] Furthermore, a lead screw nut is installed in the middle of the slider, a connecting seat three for limiting the connecting seat one or the connecting seat two is installed at one end of the slider, and a limiting block is installed at the other end of the slider.

[0015] Furthermore, a lead screw for adjusting the height of the slider is installed in the middle of the lead screw nut, a rotating shaft is installed in the middle of the lead screw, and a knob is installed at the upper end of the rotating shaft.

[0016] Furthermore, the limiting structure includes a limiting rod for limiting the rotating shaft, and a sliding groove for limiting the limiting block is provided in the middle of the limiting rod, and a limiting plate is installed at the upper end of the sliding groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] When the conveying direction of the bubble bag changes, to prevent one side of the bubble bag from becoming loose, the knob on the loose side is turned, causing the shaft to drive the lead screw to rotate. The lead screw nut, in conjunction with the lead screw, drives the slider to move upward. Connecting seat three drives one side of the roller to move upward, causing the roller to gradually tilt. One side of the roller is higher than the other side, and the raised side of the roller gradually tightens the loose bubble bag, making the bubble bag adhere to the surface of the roller. This ensures that the bubble bag can be conveyed stably when the conveying direction changes, and the bubble bag between conveying roller one and conveying roller two will not wrinkle, thus protecting the bubble bag and preventing the bubbles on the bubble bag from bursting under pressure.

[0026] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0027] Please see Figures 1-3 This utility model provides a feeding mechanism for bubble wrap, including a feeding platform 10 installed on the upper end of a swing base. The feeding platform 10 is fixedly installed on the existing swing base by bolts. When the conveying direction of the bubble wrap is adjusted, the swing base drives the feeding platform 10 to swing. Conveying roller 13 and conveying roller 2 14 for conveying bubble wrap are installed at the upper and lower ends of the right side of the feeding platform 10. The bubble wrap is located between the conveying roller 13 and conveying roller 2 14. The conveying roller 13 conveys the bubble wrap when it rotates.

[0028] The upper end of the feeding platform 10 is equipped with side plates 11 and 12 for limiting the movement of conveyor roller 13 and conveyor roller 14. Side plate 11 is fixedly installed on the upper right side of the feeding platform 10, and side plate 12 is fixedly installed on the upper front end of the feeding platform 10. A motor 15 for controlling the rotation of conveyor roller 13 is installed at the front end of side plate 12. The conveying end of the motor 15 is connected to the central shaft of conveyor roller 13, so that when the motor 15 starts, it synchronously drives the conveyor roller 13 to rotate, which facilitates the conveying of bubble bags.

[0029] A rotating roller 100 for tensioning bubble bags is installed on the left side of the feeding table 10. The rotating roller 100 includes a roller body 110, and multiple annular grooves 111 are equally spaced in the middle of the roller body 110. A protective sleeve 120, which is made of rubber, is installed in the annular grooves 111 to prevent the bubble bags from shifting. The protective sleeve 120 increases the friction between the roller body 110 and the protective sleeve 120, thus preventing the bubble bags from shifting. One side of the bubble bag is attached to the surface of the roller body 110, and an insertion hole 112 is provided at the center of the front end of the roller body 110.

[0030] A connecting seat 130 is installed at the rear end of the roller body 110. A connecting block 131 is fixedly installed on the side of the connecting seat 130 near the roller body 110, and the connecting block 131 is movably installed at the rear end of the roller body 110, so that the roller body 110 can rotate during the conveying of the bubble bag. A connecting seat 140 is installed at the front end of the roller body 110. A slide rod 141 for sliding in the insertion hole 112 is installed at the end of the connecting seat 140 near the roller body 110. When the angle of the roller body 110 is adjusted, the slide rod 141 slides in the insertion hole 112.

[0031] Two limiting structures 200 for limiting the rotation roller 100 are symmetrically installed on the left side of the feeding platform 10. The two limiting structures 200 are located at the front and rear ends of the rotation roller 100, respectively. Each limiting structure 200 includes a slider 210 for controlling the angle change of the rotation roller 100. A lead screw nut 213 is fixedly installed in the middle of the slider 210. A connecting seat 211 for limiting the connecting seat 130 or connecting seat 240 is installed at one end of the slider 210. This utility model includes two sliders 210. The connecting seat 211 on one slider 210 is movably connected to the connecting seat 130, and the connecting seat 211 on the other slider 210 is movably connected to the connecting seat 240. A limiting block 212 is fixedly installed at the other end of the slider 210.

[0032] A lead screw 220 is installed in the middle of the lead screw nut 213 to adjust the height of the slider 210. A rotating shaft 221 is fixedly installed in the middle of the lead screw 220. A knob 222 is fixedly installed at the upper end of the rotating shaft 221. By rotating the knob 222, the rotating shaft 221 drives the lead screw 220 to rotate synchronously. The lead screw 220, in conjunction with the lead screw nut 213, drives the slider 210 to move up and down, thereby causing one end of the rotating roller 100 to rise or fall.

[0033] The limiting structure 200 includes a limiting rod 230 for limiting the rotating shaft 221. The limiting rod 230 has a groove 231 in the middle for limiting the limiting block 212. By limiting the limiting block 212 through the groove 231, the slider 210 can only move up and down. The upper end of the groove 231 is equipped with a limiting plate 232 for limiting the rotating shaft 221, so that the lead screw 220 is relatively stable when it rotates.

[0034] When the conveying direction of the bubble bag changes, to prevent one side of the bubble bag from becoming loose, the knob 222 on the loose side is rotated, causing the rotating shaft 221 to drive the lead screw 220 to rotate. The lead screw nut 213, in conjunction with the lead screw 220, drives the slider 210 to move upward. The connecting seat 211 drives one side of the roller 110 to move upward, causing the roller 110 to gradually tilt. One side of the roller 110 is higher than the other side, and the raised side of the roller 110 gradually tightens the loose bubble bag, making the bubble bag adhere to the surface of the roller 110. This ensures that the bubble bag can be conveyed stably when the conveying direction of the bubble bag changes.

[0035] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
