Description

Technical Field

[0001] The utility model relates to the technical field of aluminized paper slitting, in particular to an aluminized paper slitting device. Background Art

[0002] At present, the utility model patent with the publication number of CN221338643U discloses a slitting device for the production of aluminized paper for beer labels. The patent includes a machine frame, a cutter roller, a cutter mounting shaft, and a circular cutter mounted on the cutter mounting shaft. When the aluminized paper passes through the cutter roller and the cutter mounting shaft, the circular cutter can slit the aluminized paper. The patent can synchronously lift the two ends of the cutter mounting shaft. This function can simplify the adjustment steps of the height of the cutter mounting shaft while enabling the distance between the cutter mounting shaft and the cutter roller to be adjusted, and can also keep the distance between the cutter mounting shaft and the cutter roller balanced.

[0003] However, in this patent, the height adjustment between the cutter roller and the cutter mounting shaft is independent of each other. Therefore, if you want to move the cutter mounting shaft and the cutter roller to a specific height to slit the aluminized paper so that the aluminized paper can form a certain bending degree between the cleaning roller and the cutter roller, you need to adjust the heights of the cutter mounting shaft and the cutter roller respectively. Therefore, the operation process is relatively not simple enough. Content of the Utility Model

[0004] The utility model provides an aluminized paper slitting device, which solves the above problems existing in the prior art during use.

[0005] The technical solution of the utility model is realized as follows: An aluminized paper slitting device includes a machine frame. A conveying roller group and a slitting roller group are sequentially arranged on the machine frame in the front-back direction. The slitting roller group includes a cutter mounting shaft and a cutter roller arranged one above the other. A circular cutter is arranged on the cutter mounting shaft. A height adjustment mechanism for driving the cutter roller to slide up and down is arranged on the machine frame. A synchronous and co-directional displacement mechanism is arranged between the cutter roller and the cutter mounting shaft.

[0006] The utility model is further arranged as follows: First sliders are rotatably arranged at both ends of the cutter roller, and second sliders are rotatably arranged at both ends of the cutter mounting shaft. The first sliders and the second sliders are both slidably arranged up and down on the machine frame. The height adjustment mechanism includes a motor, a synchronous belt, and two lead screws. The lead screws are rotatably arranged on the machine frame and are respectively threadedly connected to a first slider. The motor is fixedly arranged on the machine frame and its output end is connected to one of the lead screws. The synchronous belt is arranged between the two lead screws.

[0007] The present utility model is further configured as follows: The synchronous and co-directional displacement mechanism includes a vertical rod fixedly arranged on the first slider. The vertical rod extends upward, and a limiting block is fixedly arranged on the vertical rod. The limiting block is located below the second slider, and its upper end is used to abut against the lower end face of the second slider.

[0008] The present utility model is further configured as follows: The upper end of the vertical rod penetrates upward through the second slider and extends above the second slider. A chute for the vertical rod to pass through is provided on the second slider.

[0009] The present utility model is further configured as follows: An elastic abutting member for pushing the second slider downward is provided between the upper end of the vertical rod and the upper end face of the second slider.

[0010] The present utility model is further configured as follows: The cutter roller is of a hollow structure.

[0011] The present utility model is further configured as follows: The cutter mounting shaft is of a hollow structure.

[0012] In summary, the beneficial effects of the present utility model are as follows:

[0013] 1. The height adjustment mechanism of this structure can be used to adjust the up and down position of the cutter roller. At the same time, the synchronous and co-directional displacement mechanism can make the circular cutter and the cutter roller move up and down simultaneously. In this process, only by adjusting the height of the cutter roller can the overall height adjustment of the slitting roller group be completed. Therefore, the operation process is relatively more convenient.

[0014] 2. The second slider is slidably arranged up and down above the first slider, which can make the first slider press on the upper end of the limiting block under the action of gravity during the up and down movement of the second slider, so as to achieve the same-direction and synchronous height change. At the same time, the limiting block can also be used to limit the minimum distance between the cutter mounting shaft and the cutter roller, and can prevent the circular cutter and the cutter roller from colliding and being damaged.

[0015] 3. The cooperation between the guide groove and the vertical rod can make the cutter mounting shaft and the cutter roller move precisely in the same direction.

[0016] 4. The setting of the elastic abutting member can enable the device to adapt to aluminized paper of different thicknesses, and make the circular cutter form a certain pressure on the surface of the aluminized paper to ensure that the circular cutter can cut through the aluminized paper.

[0017] 5. Setting the cutter roller as a hollow structure can reduce the wear between the lead screw and the first slider.

[0018] 6. Setting the cutter mounting shaft as a hollow structure can facilitate the setting of the stiffness coefficient of the elastic abutting member, so that the elastic abutting member can push the second slider downward without generating too much force, which is convenient for the transmission of aluminized paper.

Detailed Embodiment

[0024] The following will combine the attached Figures 1-3 in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] Embodiment:

[0026] As Figures 1 to 3 shown, the present invention discloses an aluminized paper slitting device, which includes a frame 1. A conveyor roller group 2 and a slitting roller group are sequentially arranged on the frame 1 in the front-rear direction. Among them, the slitting roller group includes a cutter mounting shaft 31 and a cutter roller 32 arranged below the cutter mounting shaft 31. A circular cutter 33 is arranged on the cutter mounting shaft 31. At the same time, in this structure, a height adjustment mechanism for driving the cutter roller 32 to slide up and down is arranged on the frame 1, and a synchronous and co-directional displacement mechanism is arranged between the cutter roller 32 and the cutter mounting shaft 31.

[0027] The specific setting scheme is as follows:

[0028] At both ends of the cutting knife roller 32, first sliders 41 are rotatably arranged, and at both ends of the cutting knife mounting shaft 31, second sliders 42 are rotatably arranged. The first sliders 41 and the second sliders 42 are both arranged to slide up and down on the frame 1. The height adjustment mechanism specifically includes a motor 43, a synchronous belt 45 and two lead screws 44. Among them, the lead screws 44 are rotatably arranged on the frame 1 and are respectively threadedly connected to a first slider 41. The motor 43 is fixedly arranged on the frame 1 and its output end is connected to one of the lead screws 44. The synchronous belt 45 is arranged between the two lead screws 44.

[0029] The synchronous same-direction displacement mechanism includes a vertical rod 411 fixedly arranged on the first slider 41. The upper end of the vertical rod 411 penetrates upward through the second slider 42 and extends above the second slider 42. A chute for the vertical rod 411 to pass through, namely a guide groove 421, is formed on the corresponding second slider 42. At the same time, a limit block 412 is fixedly arranged on the outer side wall of the middle part of the vertical rod 411. The limit block 412 is located below the second slider 42 and its upper end is used to abut against the lower end surface of the second slider 42.

[0030] In addition, an elastic abutting member 413 for pushing the second slider 42 downward is arranged between the upper end of the vertical rod 411 and the upper end surface of the second slider 42. The elastic abutting member 413 can be selected as a spring.

[0031] Finally, the cutting knife roller 32 is of a hollow structure, and the cutting knife mounting shaft 31 is of a hollow structure.

[0032] The working principle of the above structure is as follows:

[0033] When the motor 43 rotates, the synchronous belt 45 and the lead screws 44 move the two ends of the cutting knife roller 32 up and down in the same horizontal state. During the up and down movement, the second slider 42 is always pressed against the upper end of the limit block 412 under the influence of gravity and the elastic abutting member 413. Thereby, the circular cutting knife 33 and the cutting knife roller 32 can be synchronously adjusted in height, and the cutting knife mounting shaft 31 and the cutting knife roller 32 can be kept parallel.

[0034] When the device needs to slit aluminized paper, the elastic abutting member 413 allows the second slider 42 to move up and down within a certain range, so that the device can facilitate the passage of aluminized paper with different thicknesses between the circular cutting knife 33 and the cutting knife roller 32 and perform slitting, which can improve the compatibility of the device.

[0035] At the same time, the conveying roller group 2 can also adopt the same installation scheme as the slitting roller group, so that the conveying roller group 2 can not only be adjusted in height, but also facilitate the passage of aluminized paper with different thicknesses and sizes from the conveying roller group 2.

[0036] It should be noted that the terms used in the present utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present utility model 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, it should not be construed as a limitation on the protection scope of the present utility model.

[0037] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
