Description

Technical Field

[0001] This utility model relates to the field of paper bag stacking and packaging, and in particular to a feeding device for paper bag stacking and sealing equipment. Background Technology

[0002] Paper bags, as packaging containers that combine environmental friendliness and commercial value, can be printed on their outer surface to decorate products and promote brands, making them widely used in retail, catering, and other industries. Currently, in the paper bag production process, after the automated bag-making machine completes the forming process, manual stacking and packaging are still required, resulting in high labor intensity and low efficiency. To address this technological bottleneck, the applicant filed a "Lifting and Stacking Device for Paper Bag Stacking and Sealing Equipment" application on the same day, disclosing a technical solution that uses a lifting and stacking mechanism to stack paper bags layer by layer into a stack, achieving automated stacking.

[0003] However, the equipment revealed significant technical defects during implementation: due to the bottom-up lifting and stacking method, the overall height of the equipment increases linearly with the increase of the stacking height of the paper bags, resulting in strict requirements on the height of the work site, which seriously restricts the promotion and application of the equipment in conventional production environments. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a feeding device for a paper bag stacking and sealing equipment that effectively reduces the vertical space occupied by the equipment.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A feeding device for a paper bag stacking and sealing equipment includes a forward and reverse steering mechanism, a height difference connecting turntable, and a feeding mechanism arranged sequentially along the material conveying direction. The height difference connecting turntable is connected between the forward and reverse steering mechanism and the feeding mechanism. The forward and reverse steering mechanism is used to alternately turn the material forward and reverse. The height difference connecting turntable has its rotation axis arranged longitudinally. The height difference connecting turntable includes a feeding station and a discharging station. The feeding station is connected to the discharging end of the forward and reverse steering mechanism, and the discharging station is connected to the feeding end of the feeding mechanism. The feeding station is higher than the discharging station. Both the feeding station and the discharging station are equipped with a conveying bin and a feeding mechanism, which are used to discharge the material from the conveying bin of the discharging station.

[0006] This invention uses a forward and reverse turning mechanism to alternately turn the material in both directions, ensuring the flatness of the paper bag in the horizontal direction. Then, the height difference is used to connect the turntable to compress the overall height of the equipment, which facilitates the subsequent integration of materials by lifting and stacking. The feeding mechanism is used to send the material into the next process.

[0007] Preferably, the forward and reverse steering mechanism includes a steering pressure head and a steering support platform that can rotate in both directions. The steering pressure head is connected to the lifting drive component. During steering operation, the steering pressure head descends and cooperates with the steering support platform to alternately rotate the material in both directions. The steering pressure head and the steering support platform clamp the material and rotate in coordination to ensure stable rotation of the material.

[0008] Furthermore, a horizontally reciprocating feed pusher is connected between the forward and reverse steering mechanism and the height difference connecting turntable. The feed pushers are respectively positioned on both sides of the steering support platform. The steering support platform is adapted to the width of the material, and the spacing between the feed pushers is adapted to the length of the material. The size of the steering support platform is adapted to the width of the material, allowing the material to enter longitudinally and then laterally, thus adapting to the feed pushers. This eliminates the need for a clearance device for the feed pushers, resulting in a simple structure and reduced costs.

[0009] Preferably, a transfer station is provided between the feeding station and the discharging station, and a conveyor bin is provided at the transfer station. Increasing the number of conveyor bins improves the utilization rate of the height difference connecting turntable and increases the transfer efficiency.

[0010] Preferably, the feeding mechanism includes a first conveying platform and a feeding pusher plate, wherein the feeding pusher plate is movably disposed laterally between the height difference connecting turntable and the first conveying platform. The feeding pusher plate is used to push the material at the discharge station onto the first conveying platform, and then the first conveying platform conveys it to the next process.

[0011] Preferably, the first conveying platform includes a first pusher plate and a conveyor belt, with the first pusher plate spaced apart on the conveyor belt.

[0012] Furthermore, the first conveying platform includes a fixed platform and a second pusher plate for pushing materials on the fixed platform. The second pusher plate is connected to a pusher drive unit that drives it to move along a rectangular motion trajectory.

[0013] Furthermore, the pushing drive unit includes a lifting plate and a horizontal rail arranged along the conveying direction, the second push plate being spaced apart on the lifting plate, and the lifting plate being arranged on the horizontal rail.

[0014] Preferably, an inclined guide plate is provided between the height difference connecting turntable and the forward and reverse steering mechanism. The inclined guide plate gradually tilts downward along the conveying direction, and the up and down adjustment of the inclined guide plate is set on the frame. This ensures that the material enters the transfer bin stably and compresses the stacked material once to prevent the material from becoming too high.

[0015] Preferably, side guide plates are provided on both sides of the conveyor at the feeding station, and the side guide plates are adjustable left and right on the frame. The side guide plates correspond to the left and right sides of the material to ensure the flatness of the material pile sides. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The X-axis is the horizontal direction, i.e., the left-right direction; the Y-axis is the vertical direction, i.e., the front-back direction; and the Z-axis is the vertical direction, i.e., the up-down direction.

[0023] The feeding device of the paper bag stacking and sealing equipment includes a forward and reverse steering mechanism 1, a height difference connecting turntable 2, and a feeding mechanism arranged sequentially along the material conveying direction. The height difference connecting turntable 2 is connected between the forward and reverse steering mechanism 1 and the feeding mechanism. The forward and reverse steering mechanism 1 is used to alternately turn the material forward and reverse. The forward and reverse steering mechanism 1 includes a steering pressure head 11 that can rotate forward and reverse and a steering support platform 12. The steering pressure head 11 is connected to a lifting drive component 13, which can be a motor or a cylinder. The steering support platform 12 includes a support plate and a rotational power source. The rotational power source drives the support plate to rotate. The steering pressure head 11 can rotate actively or passively. During the steering operation, the steering pressure head 11 descends and cooperates with the steering support platform 12 to alternately turn the material forward and reverse. The descending steering pressure head 11 and the steering support platform 12 clamp the material. The rotational power source drives the support plate to rotate, so that the openings of adjacent bags face opposite directions to avoid the bottom of the folded bags being too thick and all on the same side, ensuring that subsequent material stacking is stable. To connect the forward and reverse steering mechanism 1 and the height difference connecting turntable 2, a horizontally reciprocating feeding pusher 6 is connected between the forward and reverse steering mechanism 1 and the height difference connecting turntable 2. The feeding pusher 6 is respectively set on both sides of the steering support platform 12. The frame 7 is provided with a feeding guide rail. The feeding pusher 6 is slidably set on the feeding guide rail by a slider. The steering support platform 12 is adapted to the width of the material, and the spacing between the feeding pushers 6 is adapted to the length of the material. The structure is simple and the cost is low. Of course, a cylinder or motor can also be set between the feeding pusher 6 and the slider to drive the feeding pushers 6 on both sides to move relative to each other to adapt to materials of different sizes.

[0024] The height difference connecting turntable 2 has its rotation axis set longitudinally, allowing it to rotate vertically. The height difference connecting turntable 2 is a vertically rotating indexing turntable. The height difference connecting turntable 2 includes a feeding station 21 and a discharging station 22. The feeding station 21 is connected to the discharging end of the forward and reverse steering mechanism 1, and the discharging station 22 is connected to the feeding end of the feeding mechanism. The feeding station 21 is higher than the discharging station 22, meaning that the position of the forward and reverse steering mechanism 1 is higher than the position of the feeding mechanism, thereby reducing the initial height of subsequent lifting and stacking of materials and effectively reducing the vertical space occupied by the equipment. Both the feeding station 21 and the discharging station 22 are equipped with a conveyor 23. The inner wall of the conveyor 23 is U-shaped. In order to improve production efficiency and the utilization rate of the height difference connecting turntable 2, a transfer station 24 is provided between the feeding station 21 and the discharging station 22. The transfer station 24 is equipped with a conveyor 23, which further increases the number of conveyor 23, shortens the transfer time, improves production efficiency, and is reasonably arranged to improve the utilization rate of the height difference connecting turntable 2.

[0025] The feeding mechanism is used to deliver materials from the conveyor bin 23 of the discharge station 22. The feeding mechanism includes a first conveying platform 31 and a feeding pusher plate 32. The feeding pusher plate 32 is movably and reciprocatingly disposed between the height difference connecting turntable 2 and the first conveying platform 31. The feeding pusher plate 32 is mounted on the frame 7 via linear slide rails arranged in the left-right direction. The feeding pusher plate 32 is configured on both sides of the first conveying platform 31, or the first conveying platform 31 has a gap for the feeding pusher plate 32 to enter. The feeding pusher plate 32 is connected to a pushing drive mechanism that drives its left-right movement. The pushing drive mechanism can be a belt drive mechanism or a linear drive mechanism such as a cylinder. The pushing drive mechanism drives the feeding pusher plate 32 to extend from both sides of the conveyor bin 23, pushing materials slightly wider than the conveyor bin 23 from the conveyor bin 23 of the discharge station 22 onto the first conveying platform 31, and then conveyed to the next process via the first conveying platform 31. The first conveying platform 31 can be implemented in several ways to convey materials. For example, the first conveying platform 31 includes a first pusher plate 311 and a conveyor belt 312. The first pusher plates 311 are spaced apart on the conveyor belt 312, which is arranged in a ring on the frame 7. The conveyor belt 312 drives the first pusher plates 311 to move in a circular motion. Alternatively, the first conveying platform 31 includes a fixed platform and a second pusher plate for pushing materials on the fixed platform. The fixed platform has a gap for the second pusher plate to move. The second pusher plate is connected to a material pushing drive unit that drives it to move along a rectangular motion trajectory. The material pushing drive unit includes a lifting plate and a horizontal rail arranged along the conveying direction. The second pusher plates are spaced apart on the lifting plate. The lifting plate is mounted on the horizontal rail. The lifting plate can be mounted on a translation seat by a cylinder. The translation seat is connected to the horizontal rail by a slider, or the second pusher plate can be driven to move along a rectangular motion trajectory by a linkage mechanism.

[0026] To ensure stable material entry into the conveying chamber 23 of the height difference connecting turntable 2, an inclined guide plate 4 is provided between the height difference connecting turntable 2 and the forward and reverse steering mechanism 1. The inclined guide plate 4 gradually tilts downward along the conveying direction, with its inlet larger than its outlet. This provides initial compression of the material while ensuring stable entry into the conveying chamber 23. Furthermore, the inclined guide plate 4 is adjustable vertically on the frame 7, allowing adjustment based on the material height (which can be a single paper bag or multiple stacked paper bags), improving equipment adaptability. Various vertical adjustment methods exist, such as connecting the mounting column of the inclined guide plate 4 to the frame 7 via a guide rod with guide grooves for vertical movement of the mounting column. After height adjustment, bolts are used for tightening, or the adjustment can be directly achieved using a cylinder. To further ensure stable material entry into the conveying chamber 23 of the height difference connecting turntable 2, side guide plates 5 are provided on the left and right sides of the conveying chamber 23 at the feeding station 21, and side baffles are provided on the front and rear sides of the conveying chamber 23 at the feeding station 21. Their inlets are larger than their outlets, ensuring stable material entry into the conveying chamber 23. The side guide plate 5 is adjustable left and right on the frame 7. The side guide plate 5 can also be adjusted by guide grooves, or automatically by cylinders, motors, etc.

[0027] The working principle of this utility model is described below with reference to the accompanying drawings: The material is fed into the steering mechanism by a conveying device or manually. The lifting drive component 13 drives the steering pressure head 11 to descend, cooperating with the rotating material receiving platform to clamp it, and alternately turning in both directions to eliminate the risk of stacking tilt caused by the accumulation of thickness on one side. After turning, the material is pushed by the feeding push plates 6 on both sides through the inclined guide plate 4 and the side guide plate 5 for guiding and preliminary shaping, and then enters the feeding station 21 and conveying bin 23 of the height difference connecting turntable 2 to ensure the stability of the feeding. The height difference connecting turntable 2 rotates intermittently, transferring the paper bags through the intermediate station 24 to the discharge station 22 below. The vertical height between the feeding station 21 and the discharge station 22 is used to reduce the initial working height of the subsequent lifting and stacking. Then, the material at the discharge station 22 is pushed laterally by the feeding push plate 32 to the first conveying platform 31, and the first conveying platform 31 transfers the paper bags to the next process (lifting and stacking process).
