Description

Technical Field

[0001] The utility model relates to the technical field of laminating machines, in particular to a paper breaking mechanism of a laminating machine. Background Art

[0002] A paper laminating machine is a specialized device for laminating paper. It combines the laminating material and paper material through a rubber roller and heated rollers, creating a paper-plastic composite product. The main steps of the paper laminating machine are as follows: first, the paper material is conveyed to the laminating machine; second, the laminating material is heated by heated rollers and laminated to the paper material; third, the laminated product is pressed and conveyed; and finally, the laminated paper is cut.

[0003] In the existing paper breaking process, for example, a breaking mechanism for a laminating machine disclosed in a Chinese utility model patent (publication number CN220593462U) outputs power to the breaking roller. When laminating full-page solid color paper, the paper needs to be conveyed through the breaking roller, and the power output acts on the breaking roller, which causes the breaking roller to rub against the front side of the paper, causing the front side of the paper to be subjected to excessive force, ultimately resulting in marks on the front side of the paper, affecting the lamination quality. Utility Model Content

[0004] The technical problem to be solved by the present invention is that the existing breaking mechanism power is easily caused to have marks on the paper during use, which affects the lamination quality. In order to overcome the defects of the above existing technologies, the present invention provides a method of connecting the paper breaking roller rotation drive component with the breaking tapered roller, converting the power from the original breaking paper discharge roller to the breaking tapered roller, and realizing the synchronous rotation of the breaking paper discharge roller and the breaking tapered roller through the synchronous rotation component, thereby preventing marks from being left during the lamination process and further ensuring the overall lamination quality.

[0005] For the purpose of this utility model, the following technical solutions are adopted:

[0006] The paper-breaking roller is connected to the paper-breaking roller by a rotating drive assembly and a synchronous rotation assembly, and the paper-breaking roller is driven by the rotating drive assembly to drive the paper-breaking roller to rotate synchronously with the paper-breaking roller under the action of the synchronous rotation assembly to realize paper feeding; the paper-breaking roller is arranged on the frame, and the paper-breaking roller is driven by the rotating drive assembly to drive the paper-breaking roller to rotate synchronously with the paper-breaking roller under the action of the synchronous rotation assembly to realize paper feeding; the paper-breaking roller is arranged on the frame, and the paper-breaking roller is driven by the rotating drive assembly to the other end of the paper-breaking roller, and the paper-breaking roller is used to adjust the position of the connecting end on the paper-breaking roller through the paper-breaking roller, thereby reducing the gap in the tapered channel to realize paper breaking. The mechanism can drive the paper-breaking roller and the tapered roller to rotate synchronously under the action of the paper-breaking roller rotation drive component and the synchronous rotation component, so that the paper can be transported stably and orderly, and can prevent the paper-breaking roller and the tapered roller from excessively rubbing against the paper during the lamination and breaking process, thereby preventing marks from being left on the paper, thereby ensuring the quality of the lamination. At the same time, the paper-breaking drive component can drive one end of the tapered roller to adjust its position, and reduce the gap between the paper-breaking roller and the tapered roller during the swinging process. Finally, the gap in the tapered channel is gradually reduced to achieve the paper breaking from one end to the other, ensuring the stability and smoothness of the breaking.

The paper-breaking driving motor drives the paper-breaking active gear to rotate, so that the paper-breaking active gear drives the paper-breaking driven gear on the paper-breaking cam shaft to rotate synchronously, thereby causing the paper-breaking cam to rotate eccentrically. The outer peripheral wall of the paper-breaking cam contacts the outer peripheral wall of the paper-breaking roller at different positions to make the paper-breaking swing plate rotate and adjust. The interference amount of the paper-breaking cam is adjustable instead of the original non-adjustable structure, which further facilitates the control of the gap of the tapered channel, thereby facilitating better paper breaking. Finally, the position of one end of the tapered roller can be changed to change the gap of the tapered channel, thereby achieving precise positioning to break the paper.

[0011] Preferably, the frame includes a first vertical support plate, a second vertical support plate and at least one transverse connecting plate; the transverse connecting plate is connected between the first vertical support plate and the second vertical support plate; a smoothing component is also provided between the first vertical support plate and the second vertical support plate and on the paper feed end side of the broken conical roller.

The rotation drive motor drives the rotation drive gear to rotate, and the rotation chain causes the paper breaking roller and the tapered breaking roller to rotate synchronously.

[0014] Preferably, a paper discharge assembly is further provided on the frame and located on the paper discharge end side of the broken tapered roller, the paper discharge assembly comprising a paper discharge fixed shaft, a paper discharge rotating shaft and a paper discharge driving gear; the paper discharge fixed shaft is laterally fixed to the frame, and the paper discharge fixed shaft is spaced and distributed and rotatably connected to a paper pickup roller; the paper discharge rotating shaft is laterally distributed and rotatably connected to the frame, and the paper discharge rotating shaft is located below the paper discharge fixed shaft, the paper discharge driving gear is connected to one end of the paper discharge rotating shaft, and the rotating chain is tensioned and connected to the paper discharge driving gear, and the rotating driven gear and the rotating driving gear realize synchronous transmission; a plurality of paper discharge rollers are spaced and arranged on the paper discharge rotating shaft; the paper discharge roller is aligned with the paper pickup roller, and a paper discharge channel for paper transportation is formed between the paper discharge roller and the paper pickup roller.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 5As shown, a paper-breaking mechanism of a laminating machine includes a frame 1, a paper-breaking discharge roller 2, a paper-breaking tapered roller 3, a paper-breaking roller rotation drive assembly 4 and a paper-breaking drive assembly 5; the frame 1 includes a first vertical support plate 101 on the left, a second vertical support plate 102 on the right and at least one horizontal connecting plate 103; the first vertical support plate 101 and the second vertical support plate 102 are symmetrically distributed left and right, and the horizontal connecting plate 103 is horizontally connected between the first vertical support plate 101 and the second vertical support plate 102; the paper-breaking discharge roller 2 and the paper-breaking tapered roller 3 are both distributed in the horizontal direction left and right and are rotatably connected to the paper discharge end of the frame 1, and the paper-breaking discharge roller 2 and the paper-breaking tapered roller 3 are aligned and spaced apart up and down, and the paper-breaking discharge roller 2 and the paper-breaking tapered roller are arranged in a manner similar to the embodiment of the present invention. A tapered passage is formed between the paper-breaking roller 2 and the paper-breaking tapered roller 3 for paper to pass through. Synchronous rotation is achieved between the paper-breaking roller 2 and the paper-breaking tapered roller 3 via a synchronous rotation assembly. A paper-breaking roller rotation drive assembly 4 is disposed on the frame 1 and is in transmission connection with the right end of the paper-breaking tapered roller 3. The paper-breaking roller rotation drive assembly 4 is used to drive the paper-breaking tapered roller 3 to rotate synchronously with the paper-breaking roller 2 under the action of the synchronous rotation assembly to achieve paper conveyance. By changing the power of the paper-breaking rotation from the original paper-breaking roller 2 to the paper-breaking tapered roller 3 and achieving synchronous rotation of the paper-breaking roller 2 and the paper-breaking tapered roller 3 via the synchronous rotation assembly, it is possible to prevent marks left on the front of the paper by friction when laminating full-page solid-color paper, further ensuring the lamination quality. A paper-breaking drive assembly 5 is disposed on the frame 1 and is connected to the left end of the paper-breaking tapered roller 3. The paper-breaking drive assembly 5 is used to adjust the position of the connection end on the paper-breaking tapered roller 3, thereby reducing the gap in the tapered passage and achieving paper breaking. The mechanism can drive the paper-breaking roller 2 and the tapered roller 3 to rotate synchronously under the action of the paper-breaking roller rotation drive component 4 and the synchronous rotation component, so that the paper can be transported stably and orderly, and can prevent the paper-breaking roller 2 and the tapered roller 3 from excessively rubbing against the paper during the lamination and breaking process, thereby preventing marks from being left on the paper, thereby ensuring the quality of the lamination. At the same time, the paper-breaking drive component 5 can drive one end of the tapered roller 3 to adjust its position, and reduce the gap between the paper-breaking roller 2 and the tapered roller 3 during the swinging process, and finally realize the paper breaking from one end to the other by gradually reducing the gap in the tapered channel, ensuring the stability and smoothness of the breaking.

[0030] like Figure 1 and Figure 2As shown, the synchronous rotation assembly includes a large gear 61 and a small gear 62. The right ends of the paper break roller 2 and the tapered break roller 3 both pass through the second vertical support plate 102. The large gear 61 is sleeved onto the right end of the paper break roller 2; the small gear 62 is sleeved onto the right end of the tapered break roller 3. The large gear 61 and small gear 62 are located on the same side and mesh vertically to achieve synchronous rotation. The large gear 61 and small gear 62 achieve synchronous rotation of the paper break roller 2 and the tapered break roller 3, thereby facilitating more orderly paper conveyance. At the same time, the size of the gear ring ensures that excessive force is not applied to the front of the paper, preventing marks on the front of the paper. The paper-breaking roller rotation drive assembly 4 includes a rotation drive motor 41, a rotation drive gear 42, a rotation driven gear 43, and a rotation chain 44. The rotation drive motor 41 is mounted on the frame 1. The rotation drive gear 42 is connected to the drive shaft of the rotation drive motor 41. The rotation driven gear 43 is connected to one end of the tapered breaking roller 3. The rotation chain 44 is tensioned between the rotation driven gear 43 and the rotation drive gear 42 to achieve transmission. The rotation drive motor 41 drives the rotation drive gear 42 to rotate, and the rotation chain 44 causes the paper-breaking roller 2 and the tapered breaking roller 3 to rotate synchronously.

[0031] like Figures 1 to 5As shown, the paper-breaking drive assembly 5 includes a paper-breaking drive motor 51, a paper-breaking active gear 52, a paper-breaking cam shaft 53, a paper-breaking driven gear 54, a paper-breaking cam 55, a paper-breaking swing plate 56, and a paper-breaking roller 57; the paper-breaking drive motor 51 is arranged on the inner wall of the first vertical support plate 101 of the frame 1, and the output shaft of the paper-breaking drive motor 51 passes through the first vertical support plate 101 and is connected to the paper-breaking active gear 52 for transmission, the paper-breaking cam shaft 53 is distributed in the left and right horizontal directions and is rotatably connected between the first vertical support plate 101 and the second vertical support plate 102, and the left end of the paper-breaking cam shaft 53 passes through the first vertical support plate 101 and the second vertical support plate 102. A vertical support plate 101 is connected to the paper-breaking driven gear 54 in a transmission manner, and the paper-breaking driven gear 54 meshes with the paper-breaking driving gear 52 to achieve synchronous rotation. The paper-breaking cam 55 is eccentrically arranged on the paper-breaking cam shaft 53 and is located inside the paper-breaking driven gear 54. The paper-breaking drive motor 51 of this component provides the pulling and breaking power, and the paper-breaking drive motor 51 is an independent motor that only rotates the paper-breaking cam 55. It has sufficient power and fast speed. Compared with the original paper-breaking cam 55 and the laminating roller power sharing a motor, the rotation speed is slower. Therefore, in comparison, the paper-breaking drive assembly 5 of the present application can more effectively pull the paper apart. The paper-breaking swing plate 56 swings along the paper feed end to the paper discharge end and is connected to the outer wall of the first vertical support plate 101. The left end of the pulling and breaking tapered roller 3 is rotatably connected to the paper-breaking swing plate 56. The paper-breaking roller 57 is connected to the paper-breaking swing plate 56 in a rolling manner, and the outer peripheral wall of the paper-breaking roller 57 abuts against the outer peripheral wall of the paper-breaking cam 55 to achieve transmission. The paper-breaking swinging plate 56 is a swinging structure that replaces the lifting structure of the original lifting frame, thereby effectively solving the problem that the lifting frame and the frame 1 are worn after being used for a period of time, thereby preventing the situation of being stuck and inflexible and preventing the situation of more serious wear of the frame 1. The paper-breaking driving motor 51 drives the paper-breaking active gear 52 to rotate, so that the paper-breaking active gear 52 can drive the paper-breaking driven gear 54 on the paper-breaking cam shaft 53 to rotate synchronously, thereby causing the paper-breaking cam 55 to rotate eccentrically. The outer peripheral wall of the paper-breaking cam 55 contacts the outer peripheral wall of the paper-breaking roller 57 at different positions, so that the paper-breaking swinging plate 56 can be rotated and adjusted. The interference amount raised by the paper-breaking cam 55 is adjustable instead of the original non-adjustable structure, which further facilitates the control of the gap of the tapered channel, thereby facilitating better paper breaking. Finally, the position of one end of the tapered roller 3 can be changed to change the gap of the tapered channel, thereby achieving precise positioning and paper breaking.

[0032] like Figures 1 to 5As shown, the frame 1 is provided with a break fixed shaft 11; a paper break swing plate 56 is rotatably connected to the break fixed shaft 11 via a first bearing; a bearing mounting hole 561 is provided on the paper break swing plate 56; a penetrating swing gap is provided on the first vertical support plate 101, and the left end of the break tapered roller 3 passes through the swing gap and is rotatably connected to the bearing mounting hole 561 via a second bearing. By enabling the paper break swing plate 56 to rotate around the break fixed shaft 11 under the action of the first bearing, the linear motion of the break is changed to circumferential rotational motion, which enables the break tapered roller 3 to better cooperate with the break roller 2 in breaking, and the interference of the paper break cam can be controlled, thereby facilitating better paper breaking and improving the breaking effect and efficiency. The bottom of the paper-breaking swing plate 56 is detachably connected to a break adjustment block 58. A vertically oriented, downward-opening roller groove 581 is provided at the bottom of the break adjustment block 58. A roller shaft 582 is transversely disposed within the roller groove 581. The paper-breaking roller 57 is positioned within the roller groove 581 and rotatably connected to the roller shaft 582. The detachable break adjustment block 58 allows for replacement of paper-breaking rollers 57 of varying sizes on the break adjustment block 58, thereby adjusting the gap in the tapered channel to accommodate varying paper thicknesses and enhancing the versatility and adaptability of the entire mechanism. A grating fixed disk 531 is fixedly mounted on the paper-breaking cam shaft 53. The frame 1 is equipped with a cam sensor 532 that interacts with the grating fixed disk 531. The rotation of the grating fixed disk 531 and the cam sensor 532 coordinate to further determine and control the gap in the tapered channel, thereby facilitating better control over the integrity of the paper break.

[0033] like Figures 1 to 5 As shown, a smoothing component 7 is further provided between the first vertical support plate 101 and the second vertical support plate 102 and located on the paper feed end side of the breaking tapered roller 3; the smoothing component 7 includes a paper smoothing upper plate 71 and a paper smoothing lower plate 72; the two ends of the paper smoothing upper plate 71 are respectively arranged on the inner walls of the first vertical support plate 101 and the second vertical support plate 102, and the paper smoothing upper plate 71 is arranged horizontally; the two ends of the paper smoothing lower plate 72 are respectively arranged on the inner walls of the first vertical support plate 101 and the second vertical support plate 102, and the paper smoothing upper plate 71 is arranged horizontally, and a smoothing channel for smoothing paper is formed between the paper smoothing upper plate 71 and the paper smoothing lower plate 72; a photoelectric sensor 73 for detecting paper conveying is provided on the inner wall of the first vertical support plate 101 or the inner wall of the second vertical support plate 102, and located between the smoothing component 7 and the breaking tapered roller 3. Through the paper-smoothing upper plate 71 and the paper-smoothing lower plate 72 on the smoothing component 7, the paper can pass through the smoothing channel smoothly and flatly, and the photoelectric sensor 73 can detect the paper entering between the paper-breaking roller 2 and the paper-breaking conical roller 3, ensuring the paper-breaking effect and accuracy of the paper-breaking process.

[0034] like Figures 1 to 5 As shown, a paper discharge assembly 8 is further provided between the first vertical support plate 101 and the second vertical support plate 102 and on the paper discharge end side of the broken tapered roller 3. The paper discharge assembly 8 includes a paper discharge fixed shaft 81, a paper discharge rotating shaft 82 and a paper discharge driving gear 83; the paper discharge fixed shaft 81 is fixed laterally on the frame 1, and the paper discharge fixed shaft 81 is spaced apart and rotatably connected to the pickup roller 84; the paper discharge rotating shaft 82 is laterally distributed and rotatably connected to the frame 1, and the paper discharge rotating shaft 82 is located below the paper discharge fixed shaft 81, the paper discharge driving gear 83 is connected to one end of the paper discharge rotating shaft 82, and the rotating chain 44 is tensionedly connected to the paper discharge driving gear 83, and the rotating driven gear 43 and the rotating driving gear 42 realize synchronous transmission; a plurality of paper discharge rollers 85 are spaced apart on the paper discharge rotating shaft 82; the paper discharge roller 85 is aligned with the pickup roller 84, and a paper discharge channel for paper transportation is formed between the paper discharge roller 85 and the pickup roller 84. By rotating the paper output rotating shaft 82 on the paper output assembly 8, the paper can be driven to continue to be transported. At the same time, the paper output roller 85 and the paper pickup roller 84 facilitate the paper to be delivered more smoothly. At the same time, it can also further assist in breaking the paper, providing a conveying force to the paper during the breaking process, ensuring that the paper is stable and quickly broken.

[0035] like Figures 1 to 5 As shown, an electrostatic brush assembly 9 is further provided between the first vertical support plate 101 and the second vertical support plate 102 and at the paper outlet end of the paper outlet assembly 8. The electrostatic brush assembly 9 includes an electrostatic brush holder 91, an electrostatic brush reinforcing rod 92, and an electrostatic brush 93. The electrostatic brush holder 91 is disposed transversely on the frame 1 and is provided with transversely distributed brush holes 911. The electrostatic brush 93 is disposed transversely on the electrostatic brush reinforcing rod 92, which is disposed at the bottom of the electrostatic brush holder 91 and extends from the brush hole 911. When the paper passes through the electrostatic brush 93 during transportation, static electricity generated on the paper surface during operation of the laminating machine is eliminated, preventing the laminating belt from statically adsorbing dust in the air, and ultimately reducing the impact of dust on the laminating effect.

[0036] During use, the left and right ends of the paper-breaking roller 2 are rotatably connected to the first vertical support plate 101 and the second vertical support plate 102, and the paper-breaking roller 2 does not move vertically, and a set gap is maintained between the left end of the paper-breaking roller 2 and the left end of the tapered roller 3 and then remains stationary; this mechanism only sets the left end of the tapered roller 3 to swing, that is, when the left end of the tapered roller 3 swings upward, the gap of the tapered channel gradually decreases from left to right, so under the action of the conveying structure of the laminating machine, the paper after lamination is transported to the tapered channel. When the paper just enters the conical channel, the gap in the conical channel is greater than the thickness of the paper, which can ensure that the paper passes smoothly; when the paper needs to be broken, the paper breaking driving motor 51 on the paper breaking driving assembly 5 drives the paper breaking active gear 52 and the paper breaking driven gear 54 to rotate synchronously, thereby rotating the paper breaking cam 55 on the paper breaking cam shaft 53, and making the outer wall of the paper breaking cam 55 press against the paper breaking roller 57 at the bottom of the paper breaking swing plate 56, swinging the paper breaking swing plate 56 upward and lifting it, and finally driving the left end of the breaking tapered roller 3 to swing upward, and the gap at the rightmost end of the conical channel can clamp the paper, that is, forming a structure similar to a cutting point. Since there is a paper breaking indentation on the paper, under the action of the cutting point, as the left end of the breaking tapered roller 3 rises, the paper can be torn along the tearing notch, and in this structure, when the right end of the paper After being clamped, the gap between the tapered channels gradually decreases from right to left, that is, as the paper continues to move forward, the tapered channels clamp the paper from right to left, and at the same time, under the transmission force between the paper-breaking roller 2 and the tapered roller 3, the paper is torn smoothly along the tear. The whole action is similar to slowly tearing the paper along one side with both hands, that is, the paper is broken from the right side of the paper and slowly extends to the entire section. The paper-breaking cam 55 can cooperate with the paper-breaking roller 57 in transmission, and can also support the paper-breaking swinging plate 56 on the paper-breaking roller 57, thereby further ensuring the stability and accuracy of the swinging of the paper-breaking swinging plate 56. At the same time, by controlling the paper-breaking drive motor 51, the pressurization process of the paper-breaking cam 55 can be independently controlled, further ensuring sufficient power and speed.
