DETAILED DESCRIPTION

[0025] In order to make the purpose and the advantage of the utility model more clearly and clearly, the following is combined with example to the utility model specific description.It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the protection scope of the utility model specific request.

[0026] As Figures 1-5 shown, a kind of light paper production device, including box body 1, feeding roller 4 is arranged in the inside of box body 1 by conveying frame 2, and pressure roller 3 is rotatably installed in one side of box body 1;

[0027] Feeding mechanism 5 is rotatably installed in one side of box body 1, transmission mechanism 6 is provided on the top of box body 1, and cutting mechanism 8 is hinged by mounting rack 7 with transmission mechanism 6;

[0028] Wherein, feeding mechanism 5 includes fixed column 51, hydraulic rod 52 and support arm 53, fixed column 51 is hinged by hydraulic rod 52 with support arm 53, and support arm 53 is provided with clamping disc 54 in one side.

[0029] Refer to attached Figure 1 and Figure 2In the embodiment, the supporting arms 53 are provided in two groups and are rotatably connected to the box body 1. The fixed columns 51 are welded to the two sides of the box body 1. The hydraulic rods 52 are used to drive the supporting arms 53 to move the clamping disc 54.

[0030] In the above embodiment, the fixed columns 51 can be provided in two groups and are hingedly connected to the two ends of the hydraulic rods 52. The supporting arms 53 are connected to the box body 1 through the fixed columns 51. The ends of the supporting arms 53 are rotatably connected to the box body 1 through the rotating shafts.

[0031] Further, the hydraulic rods 52 can drive the supporting arms 53 to move, so that the clamping disc 54 moves synchronously. The light paper roll can be installed on the feeding mechanism 5 through the clamping disc 54. Therefore, when the supporting arms 53 move downward, the feeding of the light paper roll is more simple and convenient.

[0032] Further, the pressure roller 3 is installed on the side of the box body 1. The position of the pressure roller 3 is unchanged. The feeding mechanism 5 can drive the light paper roll to move upward. The light paper passes through the bottom of the pressure roller 3 and is sent between the conveying frame 2 and the feeding roller 4. Therefore, the tightness of the light paper can be adjusted through the action of the pressure roller 3 by adjusting the upward movement height of the light paper roll, so as to avoid the influence of the loose paper on the cutting accuracy in the cutting process.

[0033] Referring to the accompanying drawings Figure 2 , Figure 3 and Figure 4 , in the embodiment, the transmission mechanism 6 includes a gear reduction motor 61 and a connecting rod 63. The gear reduction motor 61 is used to drive the eccentric rotating disc 62 to rotate. The eccentric rotating disc 62 drives the mounting frame 7 to move up and down through the connecting rod 63. The gear reduction motor 61 drives the connecting rod 63 to swing through the eccentric rotating disc 62.

[0034] In the above embodiment, the gear reduction motor 61 is started to drive the eccentric rotating disc 62 to swing the connecting rod 63. The connecting rod 63 is hingedly connected to the cutting mechanism 8 through the mounting frame 7. Therefore, the cutting mechanism 8 can move up and down through the swinging of the connecting rod 63.

[0035] Further, the cutting mechanism 8 can move up and down through the linkage of the conveying frame 2 and the feeding roller 4, so as to realize the continuous cutting process in the production of the light paper. The specific structure and function of the cutting mechanism 8 will be described and introduced in detail below.

[0036] Referring to the accompanying drawings Figure 2 , Figure 3 and Figure 5 , in the embodiment, the cutting mechanism 8 includes a pressing plate 83, a spring 84 and a cutter 85. The cutter 85 is fixedly installed on one side of a connecting plate 81. The pressing plate 83 is slidably installed on the connecting plate 81 through a limiting rod 82.

[0037] In the above embodiment, the cutting knife 85 can be driven to reciprocate vertically by the transmission mechanism 6 and the mounting frame 7 for cutting the light paper, and the pressing plate 83 can be driven to reciprocate synchronously with the cutting knife 85 through the linkage of the limiting rod 82 and the connecting plate 81, so that the paper can be pressed by the pressing plate 83 to avoid moving during the cutting process.

[0038] More specifically, the connecting plate 81 is slidably connected with the box body 1 through the slide rod 9, and the connecting plate 81 abuts against the pressing plate 83 through the spring 84.

[0039] The movement of the cutting knife 85 is limited by the slide rod 9, so that the cutting knife 85 can only move vertically, and the pressing plate 83 can always be lower than the cutting knife 85 in height under the action of the spring 84, so that the pressing plate 83 can contact the paper first during the downward movement of the cutting knife 85, so that the paper can be pressed first and then cut.

[0040] The working principle of the utility model is as follows: after the hydraulic rod 52 is started to push the supporting arm 53 to drive the clamping disc 54 to move downward to a suitable height, the light paper roll is installed between the clamping disc 54, and one end of the light paper is pulled out through the bottom of the pressing roller 3 and sent between the conveying frame 2 and the feeding roller 4, the paper is sent to the lower side of the cutting mechanism 8 by starting the conveying frame 2 and cooperating with the feeding roller 4, at this time, the supporting arm 53 can be driven to move upward by starting the hydraulic rod 52, and the tightness of the light paper can be adjusted under the action of the pressing roller 3 during the upward movement, and the cutting process can be carried out when the light paper moves to the set height.

[0041] During the cutting process, the eccentric disc 62 is driven to rotate by starting the gear reduction motor 61, the eccentric disc 62 is hinged with the mounting frame 7 through the connecting rod 63, so that the mounting frame 7 can be driven to reciprocate vertically, the cutting knife 85 is fixedly installed with the mounting frame 7 through the bolt, so that the cutting knife 85 can be driven to reciprocate, the pressing plate 83 is installed on the two sides of the cutting knife 85 through the connecting plate 81 and the limiting rod 82, and the pressing plate 83 is lower than the cutting knife 85 under the action of the spring 84, so that the pressing plate 83 moves downward synchronously and contacts the paper first during the downward movement of the cutting knife 85, the paper is pressed, then the cutting knife 85 falls to cut the paper, and the continuous cutting process can be realized by cooperating the conveying frame 2 with the transmission mechanism 6.

[0042] The above is only the preferred embodiment of the utility model, it should be pointed out that for ordinary technical personnel in the prior art, on the premise of not departing from the principle of the utility model, a number of improvements and refinements can be made, these improvements and refinements should also be regarded as the protection scope of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the field without special description and limitation.
