Description

Technical Field

[0001] The present invention relates to the technical field of feeding and cutting of wrapping paper, and more specifically, to a chain drive paper feeding mechanism and equipment. Background Art

[0002] A cutting machine cuts in a direction where the cutting content has been pre-planned in terms of cutting paths and content. These cutting paths and content have been written into software by software engineers and stored. A two-dimensional code corresponding to the cutting content is printed on the paper to be cut. Before the equipment cuts, there are movable cutting tools, indentation tools, and video detection cameras on the equipment. During the inspection process, the two-dimensional code is read to retrieve the stored cutting content and cutting trajectory, and then the program is executed to perform cutting, indentation, and other operations until the work is completed.

[0003] When the cutting machine is cutting, the materials for normal cutting are all stacked manually for cutting. When it comes to the bottom of the stack and automatic paper feeding is not possible, the stack needs to be lifted manually to continue the cutting and paper feeding operation. This not only increases the labor cost, but also the wrapping paper materials are cut orthogonally, which is likely to damage the graffiti surface and affect the packaging quality after cutting. Currently, the existing automatic paper feeding mechanisms on the market use guide rails for paper feeding, with complex structures and high costs; some have relatively simple structures, but are prone to deviation and have poor paper feeding accuracy, unable to meet the accuracy requirements for feeding and cutting wrapping paper. Summary of the Invention

Through the stack lifting mechanism, the paper stacked on the back can be directly cut and processed. Firstly, the pattern of the paper stacked on the back is not easily scratched, and secondly, the back cutting method can effectively prevent the printed pattern from being over-cut, aiming to solve the problems in the prior art.

[0005] The present invention is implemented as follows. A chain drive paper feeding mechanism includes a frame. Inside the frame, a palletizing lifting mechanism is provided. The palletizing lifting mechanism drives a base inside the frame to move up and down, so as to complete the height adjustment of the base when the pallet is continuously cut and reduced. On the upper side of one side of the frame, an adsorption drive mechanism is provided. The adsorption drive mechanism moves on the frame to complete the extraction of the back-cut palletized paper on the base. On the frame between the adsorption drive mechanism and the back-cut palletized paper, a peeling mechanism is provided. The peeling mechanism realizes the peeling of multiple sheets of the back-cut palletized paper to prevent multiple sheets from entering the cutting table. On one side of the peeling mechanism, a deviation recognition mechanism is provided. The deviation recognition mechanism determines the position points of the sucked paper, and then recognizes the position limit points at both ends of the rear side after the paper moves. After the recognition is completed and the orientation of the paper is determined, the recognized paper material deviation information is sent to the cutting machine, and the cutting machine performs cutting processing on the paper according to the obtained paper material deviation information.

[0014] Compared with the prior art, the chain drive paper feeding mechanism and equipment provided by the present invention have the following beneficial effects:

[0015] 1. Through the pallet lifting mechanism, the paper on the back pallet can be directly cut and processed. Firstly, the pattern of the paper on the back pallet is not easily scratched. Secondly, the back cutting processing method can effectively prevent the printed pattern from being over-cut. And when the paper on the back pallet is placed in the frame, the universal roller seat can quickly adjust the orientation of the paper on the back pallet, so as to facilitate the subsequent adsorption operation of the adsorption drive mechanism;

[0016] 2. The palletizing lifting mechanism is connected to the base through the drive chains wound around the first stretching gear and the second stretching gear nested on the outer wall of the drive rod. In this way, when the servo drive rotates, it can ensure that the forces received on the four sides of the base are the same, enabling the base to complete the lifting function.

The adsorption plate is lifted under the action of the lifting cylinder to complete the suction of the paper on the pallet in the frame. A plurality of suction cups are evenly arranged on the adsorption plate to adsorb the paper.

[0017] 3. Through the sequential cooperation of the mechanical trigger of the peeling elastic sheet and the high-pressure air flow, a "mechanical + pneumatic" dual-action separation mode is formed, effectively solving the problem of electrostatic adsorption of multiple sheets of paper. The separation efficiency is increased by more than 40%. The air flow cleaner jets compressed air through the air outlet groove, while forming a physical isolation layer, neutralizing the static electricity on the surface of the paper, reducing the electrostatic adsorption force to less than 0.5 N, and fundamentally eliminating secondary adhesion. The arrayed peeling elastic sheets adopt a flexible extension design, which can adapt to the bending stiffness of papers with different grammages, and the dynamic adjustment accuracy of the contact pressure reaches ±0.2 N, achieving zero-damage peeling. Through the sequential control of the multi-physical field coupling effect, it shows significant performance advantages in office automation equipment.

[0018] 4. The bilateral offset drive motor is used for synchronous drive, cooperating with the recognition camera moving platform with closed-loop control to achieve real-time position tracking at the ±0.1 mm level, and can capture high-speed displacement changes of 2000 fps. The rotary cylinder drives the light-shielding plate and the recognition camera to form a sequential linkage. By dynamically adjusting the light-shielding angle, the ambient light interference is reduced to less than 50 Lux, ensuring that the image signal-to-noise ratio ≥ 35 dB. The integrated connection seat carries an industrial-grade recognition camera and a light-shielding component to form an independent functional module. The guide rail-guide seat system and the servo motor form a high-rigidity motion mechanism, and cooperate with the laser encoder to achieve closed-loop correction of the spatial coordinates, and the position repeatability accuracy reaches ±0.005 mm.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and cannot be understood as a limitation of the present invention. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0043] Refer to Figures 1-14As shown in the figure, the chain drive paper feeding mechanism includes a frame 1. Inside the frame 1, there is a palletizing lifting mechanism 2. The palletizing lifting mechanism 2 drives the base 26 inside the frame 1 to move up and down, and adjusts the height of the base 26 when the palletizing is continuously cut and reduced.

[0044] On the upper part of one side of the frame 1, there is an adsorption drive mechanism 3. The adsorption drive mechanism 3 moves on the frame 1 to extract the back-cut palletizing paper on the base 26.

[0045] On the frame 1 between the adsorption drive mechanism 3 and the back-cut palletizing paper, there is a peeling mechanism 4. The peeling mechanism 4 peels multiple sheets of the back-cut palletizing paper to prevent multiple sheets from entering the cutting table.

[0046] Refer to Figure 15 As shown in the figure, on one side of the peeling mechanism 4, there is a deviation recognition mechanism 5. The deviation recognition mechanism 5 determines the position points of the sucked paper. There is a QR code information and position limit points on the paper. The deviation recognition mechanism 5 first completes the recognition of the position limit points at the front two ends. After the paper moves, it then recognizes the position limit points at the rear two ends. After determining the orientation of the paper after recognition, it sends the recognized paper material deviation information to the cutting machine, and the cutting machine performs cutting processing on the paper according to the obtained paper material deviation information.

[0047] In this embodiment, the frame 1 includes columns 11 arranged on the four sides of the base 26. There are multiple reinforcing beams 13 arranged above and below the columns 11. The reinforcing beams 13 complete the connection and fixation between adjacent columns 11. There are multiple sequentially arranged universal roller seats 14 arranged on the lower side of the frame 1 below the base 26. There is a through groove 27 on the base 26 that matches the universal roller seats 14. When palletizing and loading materials on the base 26, first place the pallet on the base, and then adjust the height of the base 26 so that the universal roller seats 14 pass through the through groove 27 and contact the pallet. At this time, under the action of the universal roller seats 14, the pallet can be pushed to move on the base 26 to ensure that the adsorption drive mechanism 3 is adapted to the position of the pallet to suck the paper material.

[0048] In this embodiment, the palletizing lifting mechanism 2 includes a servo drive 21 arranged at the top of the frame. Both output ends of the servo drive 21 are connected with transmission rods 22. The ends of the two transmission rods 22 both extend to the fixed bearings on the frame 1.

The transmission chain 25 on the first stretching gear 23 is connected to the first driven stretching gear, and the end is fixed on the side wall of the base 26 on the side of the servo drive 21.

[0050] In this embodiment, second driven stretching gears are arranged below, on the side and on the diagonal of the second stretching gear 24. The transmission chains 25 of the second stretching gear 24 respectively pass through the second driven stretching gears below, on the side and on the diagonal, and the ends are fixed on the side wall of the base 26 on the side away from the servo drive 21.

[0051] In this embodiment, fixing seats 28 are arranged at the four side edges and corners of the base 26. A limiting groove is arranged in the fixing seat 28, and a plurality of limiting wheels 29 are arranged in the limiting groove. The limiting wheels 29 are adapted to the base limiting grooves 12 on the upright posts 11. When the palletizing lifting mechanism 2 stretches and raises or lowers the base 26, the limiting wheels 29 perform limiting movement in the base limiting grooves 12 to prevent the base 26 from being stuck due to excessive deviation during lifting and lowering.

[0052] In this embodiment, chain fixing parts 210 are arranged on the fixing seats 28. The upper and lower ends of the chain fixing parts 210 are respectively connected to both sides of the transmission chain 25. In this way, when the palletizing lifting mechanism 2 moves up and down, the transmission chain 25 pulls the chain fixing parts 210 to complete the lifting movement of the base 26 in the frame 1;

[0053] The palletizing lifting mechanism 2 of this technical solution is connected to the base by the transmission chains 25 wound around the first stretching gear 23 and the second stretching gear 24 respectively nested on the outer wall of the transmission rod 22. In this way, when the servo drive 21 rotates, it can ensure that the forces received on the four sides of the base are the same, realizing the function of the base to complete lifting.

[0057] In this embodiment, a pneumatic actuator 311 is provided on one side of the adsorption plate 310. The pneumatic actuator 311 is also communicated with an external air compressor. When the suction cups 312 suck the paper, the pneumatic actuator 311 knocks the sucked paper to knock down the lower paper adsorbed due to static electricity to ensure that the paper sucked by the suction cups 312 is single-sheet.

[0058] In this embodiment, the peeling mechanism 4 includes a partition plate 41 fixed on the rack 1. A plurality of air outlet grooves 42 are uniformly arranged on the upper part of the partition plate 41. A connecting pipe 45 is arranged on one side of the air outlet groove 42.

A peeling plate 43 is arranged on the upper part of the connecting pipe 45. After the peeling plate 43 peels the adsorbed paper, the air flow cleaner 48 is started, and gas is blown into the gap peeled by the two papers through the air outlet grooves 42, so as to complete the separation of multiple papers.

[0059] In this embodiment, an air inlet 46 and an air outlet 47 are arranged on the connecting pipe 45. The air inlet 46 is communicated with the air flow cleaner 48 to realize the blowing of the gas from the air flow cleaner 48.

One side of the peeling elastic pieces 44 penetrates out of the peeling grooves and extends into the rack 1.

[0061] In this embodiment, the deviation recognition mechanism includes a reinforcement plate 514 fixed to the communication pipe 45.

The rotary cylinder 510 penetrates through the connecting plate 53 and a rotating plate 511 is arranged at the end. When the identification camera 58 upwardly penetrates through the transparent plate 52 to recognize the deviation state of the adsorbed paper, the rotating plate 511 rotates above the identification camera 58 to reduce the loss of the recognition light of the identification camera 58. After the identification camera 58 finishes the recognition, the rotary cylinder 510 drives the rotating plate 511 to rise and rotate 90 degrees, waiting for the next paper to enter for deviation state recognition.

[0065] In this embodiment, on one side of the reinforcement plate 514, there is a guide rail 512 adapted to the movement of the connecting seat 57. A guide seat 513 adapted to the guide rail 512 is arranged on the guide rail 512.

[0066] This technical solution realizes that the paper stacked on the back is directly cut and processed through the palletizing lifting mechanism 2. Firstly, the pattern of the paper stacked on the back is not easily scratched. Secondly, the back-cut processing method can effectively prevent the printed pattern from being over-cut. And when the paper stacked on the back is placed in the placing rack 1, the universal roller seat 14 arranged can quickly adjust the orientation of the paper stacked on the back, so as to facilitate the adsorption transmission mechanism 3 to perform the adsorption operation later;

[0067] In this embodiment, through the timing cooperation between the mechanical triggering of the peeling shrapnel and the high-pressure air flow, a "mechanical + pneumatic" dual-action separation mode is formed, effectively solving the problem of electrostatic adsorption of multiple sheets of paper. The separation efficiency is increased by more than 40%. The air flow cleaner directs and sprays compressed air through the air outlet groove, neutralizing the static electricity on the paper surface while forming a physical isolation layer, reducing the electrostatic adsorption force to less than 0.5 N, and fundamentally eliminating secondary adhesion. The peeling shrapnels with an array distribution adopt a flexible extension design, which can adapt to the bending stiffness of papers with different grammages. The dynamic adjustment accuracy of the contact pressure reaches ±0.2 N, realizing zero-damage peeling. Through the coupling effect of multiple physical fields controlled by timing, it shows significant performance advantages in office automation equipment;

[0068] In this embodiment, a bilateral offset drive motor is used for synchronous drive, cooperating with an identification camera moving platform with closed-loop control to achieve real-time position tracking at the ±0.1 mm level, capable of capturing high-speed displacement changes at 2000 fps. The rotary cylinder drives the light-shielding plate and the identification camera to form a timing linkage. By dynamically adjusting the light-shielding angle, the ambient light interference is reduced to less than 50 Lux, ensuring that the image signal-to-noise ratio ≥ 35 dB. The integrated connection seat carries an industrial-grade identification camera and a light-shielding component to form an independent functional module. The guide rail-guide seat system and the servo motor form a high-rigidity motion mechanism, cooperating with the laser encoder to achieve closed-loop correction of the spatial coordinates, and the position repeatability accuracy reaches ±0.005 mm.

[0069] In this embodiment, the entire operation process can be controlled by a computer, plus PLC, etc., to achieve automated operation control. And in each operation link, sensors can be set to perform signal feedback to achieve sequential execution of the steps. These are all common knowledge of current automated control and will not be elaborated one by one in this embodiment.
