Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and in particular to a paper feeding device. Background Technology

[0002] In existing technologies, when packaging items, it is necessary to ensure that the paper is placed flat on the items. Items are not limited to fabrics and clothing. Traditional paper-laying devices generally use suction cups to lift and press the paper downwards. That is, when the detection mechanism detects that the paper length has reached the set value, the paper-cutting component cuts it, and at the same time, the suction cups hold the paper and move it downwards to lay it. However, the suction cups may not be able to hold the paper firmly, resulting in the paper falling off. This can cause wrinkles and unevenness in the paper laying, requiring manual assistance to flatten the paper. In addition, the cutting length of traditional paper-laying devices is fixed and cannot be adjusted, so the cutting length of the paper cannot be changed. Furthermore, traditional paper-laying devices are bulky, inflexible in operation, and inconvenient for threading paper, resulting in low work efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a paper feeding device that solves the technical problem in existing paper feeding devices where the use of suction cups to adhere paper during the feeding action easily leads to paper falling and wrinkling.

The first roller is slidably mounted on the support frame. Paper passes under the first roller, and the first roller can slide down under its own weight to tension the paper. When the first roller contacts the positioning sensor, the positioning sensor transmits a signal to the control component, which controls the paper clamping component to clamp the paper and the paper pressing component to release the paper.

[0012] Preferably, the device further includes an air blowing pipe, an air pump, and an air source. The air blowing pipe is mounted on the bracket and positioned on one side of the cylinder clamp. The air outlet of the air blowing pipe is located below the clamping part of the cylinder clamp to flatten the paper. The air source supplies air to the air blowing pipe through the air pump to flatten the paper.

[0013] Preferably, the drive assembly includes a first drive motor and a transmission mechanism.

A rotating support shaft drives the paper to move, with one end of the paper pressing onto the paper pressing assembly, saving paper feeding time and improving work efficiency. After the paper pressing assembly presses the paper, the paper clamping assembly moves towards the paper and clamps it. The paper pressing assembly releases the paper, and the paper clamping assembly moves away from the paper pressing assembly. Upon reaching a certain position, the paper detaches from the paper pressing assembly, and simultaneously, a straightening assembly pulls the paper down, causing it to lay flat on the object. During the paper pulling process, the cylinder clamp is more secure than the suction cup, effectively preventing the paper from falling and avoiding wrinkles during its descent.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0030] This specific embodiment provides a paper feeding device that solves the technical problem in the prior art where the paper feeding action is achieved by using a suction cup to adsorb the paper, which easily leads to the paper falling off and wrinkling.

[0031] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations represented in the embodiments below are not limited to those necessary for the solution of the invention described in the claims.

[0032] Reference Figures 1-7The present invention provides a paper feeding device, including a support frame 1, a paper feeding assembly, a paper pressing assembly, and a paper clamping assembly, wherein the paper feeding assembly, the paper pressing assembly, and the paper clamping assembly are sequentially arranged on the support frame 1, wherein:

[0033] The paper feeding assembly includes two rotatable support shafts 21. The support shafts 21 are located at the first end of the support frame 1. The two support shafts 21 are separated by a certain distance and are used to support the paper. They are tangent to the two support shafts 21. The support shafts 21 rotate, thereby driving the paper to move. One of the support shafts 21 is the drive shaft. The drive shaft is connected to the second drive motor, which facilitates the second drive motor to drive the paper to move through the drive shaft.

[0034] like Figure 2 As shown, the paper pressing assembly includes a receiving plate 41, a pressing block 42, and a first telescopic cylinder 43. The first telescopic cylinder 43 is connected to a control assembly, so that the control assembly controls the extension and retraction of the first telescopic rod of the first telescopic cylinder 43. The pressing block 42 is disposed on the telescopic rod of the first telescopic cylinder 43. The first telescopic cylinder 43 drives the pressing block 42 to move closer to and away from the receiving plate 41, so as to press and release the paper disposed between the pressing block 42 and the receiving plate 41.

[0035] like Figure 4-5 As shown, the paper clamping assembly is located on the side of the paper cutting assembly away from the paper feeding assembly. It includes a cylinder clamp 61, a bracket 62, and a drive assembly 63. The cylinder clamp 61 is mounted on the bracket 62, and the opening and closing of the cylinder clamp 61 achieves the clamping and releasing of the paper. The bracket 62 is mounted on the drive assembly 63, and the drive assembly 63 drives the cylinder clamp 61 to reciprocate, thereby achieving the paper pulling action. The cylinder clamp 61 and the drive assembly 63 are electrically connected to the control assembly, so that the control assembly controls the action of the drive assembly 63 and the cylinder clamp 61. There are two cylinder clamps 61 to ensure that the paper can slide out in parallel. In addition, the cylinder clamp 61 holds the paper firmly relative to the suction cup, reducing the chance of the paper falling off, thus reducing the probability of wrinkles.

[0036] With this setup, the rotating support shaft 21 drives the paper to move, with one end of the paper pressing against the paper pressing component, saving paper feeding time and improving work efficiency. After the paper pressing component presses the paper, the paper clamping component moves towards the paper and clamps it. The paper pressing component releases the paper, and the paper clamping component moves away from the paper pressing component. After reaching a certain position, the paper detaches from the paper pressing component, and at the same time, the straightening component pulls the paper down, causing the paper to lay flat on the item. During the paper pulling process, the cylinder clamp is more firmly held than the suction cup, which can effectively prevent the paper from falling and avoid the problem of the paper wrinkling during the fall.

[0037] The paper can be laid on the fabric to facilitate packaging the fabric.

[0038] In this embodiment, a control component is also included. The first telescopic cylinder 43, the cylinder clamp 61, and the drive component 63 are electrically connected to the control component so that the control component controls the first telescopic cylinder 43, the drive component 63, and the cylinder clamp 61 to move. The control component is PLC controlled for easy operation. Specifically, it can be a Siemens S7-200.

[0039] In this embodiment, for rolls of paper, which need to be cut into sheets during use, the paper feeding device also includes a paper cutting component, such as... Figure 2-3 As shown, the paper cutting assembly is positioned between the paper pressing assembly and the paper pulling assembly. The paper cutting assembly is located on the side of the paper pressing assembly away from the straightening assembly. It includes a cutter 51, a second telescopic cylinder 52, a cutting plate 53, a floating plate 55, an elastic element 54, and a mounting plate 56. The cutting plate 53 is mounted on the support frame 1. The mounting plate 56 is mounted on the second telescopic rod of the second telescopic cylinder 52. The cutter 51 is mounted on the mounting plate 56. One end of the elastic element 54 is fixedly mounted on the mounting plate 56, and the other end is mounted on the floating plate 55. In the non-cutting state, the bottom of the floating plate 55 is lower than the height of the blade of the cutter 51. This prevents the blade of the cutter from scratching others. The second telescopic cylinder 52 moves the cutter 51 and the floating plate 55 closer to and away from the cutting plate 53. When the floating plate 55 contacts the cutting plate 53, the second telescopic cylinder 52 is electrically connected to the control assembly. Next, the control component controls the extension and retraction of the second telescopic rod of the second telescopic cylinder 52. The second telescopic rod of the second telescopic cylinder 52 is connected to the cutter 51 through the mounting plate 56. The second telescopic cylinder 52 drives the cutter 51 and the floating plate 55 to move closer to and away from the cutting plate 53. When the floating plate 55 contacts the cutting plate 53, since the floating plate 55 is connected to the mounting plate 56 through the elastic element 54, the floating plate will move upward, so that the blade of the cutter contacts the paper and cuts the paper. When the floating plate 55 contacts the cutting plate 53, it can also position the paper and prevent the paper from moving. At the same time, the control component can control the distance of movement of the drive component 63. This ensures the consistency of the paper length. People can change the control component and change the distance of movement of the drive device, thereby changing the length of the cut paper.

[0040] In addition, to facilitate paper clamping by the paper clamping assembly, the cutting plate 53 is fixed on the support frame by the third telescopic cylinder. When cutting paper, the second telescopic cylinder and the third telescopic cylinder move simultaneously, so that the cutter 51 comes into contact with the cutting plate 53. After the paper is cut, the second telescopic rod of the second telescopic cylinder and the third telescopic rod of the third telescopic cylinder retract, providing space for the paper clamping assembly and facilitating paper clamping by the paper clamping assembly.

[0041] In this embodiment, a straightening component is also included, such as... Figure 7As shown, the straightening assembly is positioned between the paper feeding assembly and the paper pressing assembly. The straightening assembly includes a first roller 31 and a positioning sensor 32. The positioning sensor 32 is electrically connected to the control assembly and transmits the received signal to the control assembly, facilitating the movement of the paper clamping assembly. The first roller 31 is slidably mounted on the support frame 1. Paper passes under the first roller 31, and the first roller 31 slides downwards under its own weight, tautning the paper and keeping it flat. That is, after the paper leaves the roll, it passes under the first roller 31, causing the paper pressing assembly to press the paper firmly. The first roller 31 moves downwards under its own weight, and when it reaches a certain point, it contacts the positioning sensor 32. The positioning sensor detects the positioning of the first roller 31 and transmits this information to the control assembly, thus facilitating the control assembly's control of the paper clamping assembly's movement. The positioning sensor 32 can be located in two places, at opposite ends of the movement of the first roller.

[0042] like Figure 4-5 As shown, in this embodiment, to ensure that the cut paper can be laid out flat, an air blowing pipe 7, an air pump, and an air source are also included. The air blowing pipe 7 is mounted on the support 62 and positioned on one side of the cylinder clamp 61. The air outlet of the air blowing pipe 7 is located below the clamping part of the cylinder clamp 61 to blow the paper flat. The air source supplies air to the air blowing pipe 7 through the air pump to blow the paper flat. The air pump is connected to the control component, which controls the opening and closing of the air pump. After the paper cutting assembly cuts the paper, the cut pieces of paper move towards each other under the action of gravity. At the same time, since the paper clamping assembly is still clamping the other end of the paper, the laid-out paper will be uneven. At this time, the air pump is turned on, and the gas is discharged from the outlet of the air blowing pipe 7 to prevent the paper from sagging and ensure that the paper is laid out flat.

[0043] like Figure 4-5 As shown, in this embodiment, in order to facilitate the movement of the support 62, the drive assembly 63 includes a first drive motor 631 and a transmission mechanism 632. The first drive motor 631 is mounted on the support frame 1, and the transmission mechanism 632 is rotatably mounted on the support frame 1. The first drive motor 631 is connected to the transmission mechanism 632 to drive the transmission mechanism 632 to move. The support 62 is fixed on the conveyor belt 6321 of the transmission mechanism 632. The movement of the conveyor belt 6321 drives the support 62, which facilitates the reciprocating motion of the cylinder clamp 61 on the support 62.

[0044] In this embodiment, the support 62 is equipped with a rotating arm 65, a rotating cylinder 67, and a rotating shaft 66. The cylinder clamp 61 is fixed on the rotating shaft 66. One end of the rotating arm 65 is fixed on the rotating shaft 66, and the other end is hinged to the telescopic rod of the rotating cylinder 67. When the telescopic rod of the rotating cylinder 67 extends or retracts, it drives the rotating arm 65 to move, thereby driving the rotating shaft 66 to rotate and changing the angle of the cylinder clamp 61. In order to ensure that the paper can fall smoothly onto the paper receiving platform, after the paper is cut by the paper cutting component, the cut end falls. Therefore, the support 62 is equipped with a mechanism to slow down the falling speed of the paper. At the same time, the rotating cylinder 67 is activated to drive the cylinder clamp 61 to rotate and move closer to the paper receiving platform, which facilitates the laying of the paper.

[0045] like Figure 6 As shown in this embodiment, to prevent the paper roll from shifting left and right during paper feeding, the paper feeding assembly also includes a limiting plate 24, a limiting block 22, and two limiting rods 23. The limiting block 22 is adjustablely mounted on the limiting plate 24 and has a limiting hole 221. The limiting rods 23 are detachably installed in the limiting holes 221. There are two limiting rods 23 and two limiting blocks 22. The paper roll is placed in the space formed by the two limiting rods 23. This prevents the paper roll from moving left and right when it rotates. At the same time, for different paper rolls, the distance between the two limiting rods 23 can be adjusted by sliding the limiting block 22 to accommodate paper rolls of different widths.

[0046] like Figure 7 As shown, in this embodiment, in order to ensure the integrity of the paper and avoid it being scratched by the edge of the receiving plate 41 when it is close to the paper pressing assembly, a rotatable roller 44 is provided on the side of the paper pressing assembly near the straightening assembly, and the roller 44 protrudes from the side of the receiving plate 41. The paper passes over the roller 44 and falls onto the receiving plate 41. When the paper moves, it drives the roller 44 to rotate, so as to avoid the edge of the receiving plate 41 of the pressing assembly scratching the paper.

[0047] like Figure 4-5 As shown, in this embodiment, to facilitate paper ejection from the cylinder clamp 61, the paper clamping assembly also includes an ejection cylinder 64 and a support 68. The support 68 is mounted on the transmission belt of the transmission mechanism 632. The ejection cylinder 64 is disposed between the support 68 and the bracket 62 to drive the bracket 62 to move, causing the cylinder clamp 61 to detach from the paper. The control component is electrically connected to the ejection cylinder 64. Specifically, when the rotary cylinder 67 drives the cylinder clamp 61 to rotate to the correct position, the cylinder clamp 61 releases the paper. At the same time, the ejection cylinder 64 drives the bracket 62 to move away from the paper, thereby causing the paper to detach from the cylinder clamp 61.

[0048] In this embodiment, in order to stop the equipment operation in time in case of an emergency, an operating handle with buttons is also included. The operating handle is connected to the control component, and people can control the opening and stopping of the paper feeding device by pressing the buttons.

[0049] The specific operating sequence is as follows: The user manually passes one end of the paper roll under the first roller 31 and places it on the receiving plate 41. The first telescopic cylinder 43 is driven to press the paper against the pressure block 42. The first roller 31 moves downwards under its own weight and contacts the positioning sensor 32. The positioning sensor 32 transmits the signal indicating that the first roller 31 has reached its position to the control component. The control component then controls the drive component 63 to move, causing the support 62 to move towards the paper. Once the support reaches the designated position, the control component controls the cylinder clamp 61 to open, clamping the paper. Simultaneously, the control component controls the first telescopic cylinder 43 to retract, releasing the paper and allowing the clamping component to hold the paper and move it away from the pressure block. The paper assembly moves in a directional direction, and simultaneously, under the tension of the paper, the first roller 31 moves upward, separating from the positioning sensor. When the drive assembly 63 moves to a certain position, the control assembly controls the drive device to stop moving, and simultaneously controls the first telescopic cylinder 43 to move to clamp the paper, and the second telescopic cylinder 52 to move to cut the long paper. The paper falls downward under the action of gravity, and at the same time, the control assembly controls the cylinder clamp 61 to release, facilitating the paper to fall. In addition, the paper set between the support shaft 21 and the paper pressing assembly is not under the tension of the paper clamping assembly, and the first roller 31 moves downward again under its own gravity. This cycle repeats to complete the cutting of the roll of paper. By changing the data of the control assembly, the length of the paper to be cut can be changed. During the cutting process of a roll of paper, continuous cutting can be achieved, avoiding paper waste and greatly improving the working efficiency of the paper feeding device.
