Trimming and stripping rewinding machine

Abstract

The utility model discloses a trimming and stripping rewinding machine which comprises a fixing plate, a trimming roller, a paper feeding roller, a stripping plate and a paper winder are arranged on the fixing plate, a trimming cutting ring is installed on the trimming roller, and the trimming and stripping rewinding machine further comprises a tightness adjusting mechanism. Therefore, the friction between the paper can be reduced, and the paper is prevented from being damaged due to friction. By arranging the tightness adjusting mechanism, in the paper conveying process, paper winds around a tightness adjusting rod, at the moment, a spring is in a compressed state, and therefore when the paper is loose, the elastic force of the spring drives a supporting block and the tightness adjusting rod to move, and the paper is tightened; when the paper is too tight, the paper extrudes the tightness adjusting rod, so that the spring is contracted, the paper is loosened to avoid too tight, and normal conveying of the paper is guaranteed.

Description

Technical Field

[0001] The utility model relates to the technical field of rewinding machines, in particular to an edge trimming and stripping rewinding machine. Background Art

[0002] The rewinder is a special equipment for paper, mica tape and film. Its purpose is to rewind the paper rolls produced by the paper machine in sequence. After rewinding, the paper is made into finished paper and shipped out of the factory. It has become a development trend in the papermaking machinery industry to use AC drive instead of DC drive for rewinders. The paper rolls rolled by the paper reel are relatively soft, and there may be damage or breakage inside, uneven edges on both sides, and paper width. Most of them cannot be directly used in paper processing or printing machines.

[0004] The above patent has the following problems:

[0005] 1) The guide roller is not connected to the driving mechanism, so the paper will rub against the guide roller during the transmission process, which will cause paper wear;

[0006] 2) When the paper being transported is loose, it will cause uneven trimming, thus affecting the trimming effect; if the paper is too tight, it may cause the paper to break, thus affecting normal processing. Utility Model Content

[0007] In view of the problems existing in the existing trimming, peeling and rewinding machine, the utility model is proposed.

[0008] Therefore, the purpose of the utility model is to provide a trimming, peeling and rewinding machine, which solves the problem that the guide roller in the above-mentioned patent is not connected to the driving mechanism, so the paper will generate friction with the guide roller during the transmission process, which will cause paper wear; when the transmitted paper becomes loose, it will cause uneven trimming, thereby affecting the trimming effect; if the paper is too tight, it may cause the paper to break, thereby affecting normal processing.

[0009] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0011] As a preferred solution of the trimming, peeling and rewinding machine described in the utility model, the paper feeding roller is located below the trimming roller, and the peeling plate is located between the trimming roller and the paper feeding roller.

[0012] As a preferred solution of the trimming, peeling and rewinding machine described in the utility model, it also includes a first guide wheel and a second guide wheel, the first guide wheel and the second guide wheel are both rotatably connected to the fixed plate through bearings, and the rear ends of the first guide wheel and the second guide wheel are connected to the output shaft of the motor through a coupling.

[0013] As a preferred solution of the trimming, stripping and rewinding machine described in the utility model, wherein: the tightness adjustment mechanism includes two sets of tightness adjustment components;

[0014] The tension adjustment assembly comprises a first support block slidably connected to the fixed plate, a tension adjustment rod is rotatably connected to the first support block via a bearing, and one end of the tension adjustment rod is connected to a spring.

[0015] As a preferred solution of the trimming, peeling and rewinding machine described in the utility model, wherein: two notches are provided on the fixed plate, and sliding grooves are provided on the inner walls of the two notches, and a slider is welded on the first support block, and the sliders on the two first support blocks are respectively slidably connected with the sliding grooves on the inner walls of the two notches.

[0017] As a preferred solution of the trimming, stripping and rewinding machine described in the utility model, wherein: a motor is installed on the first support block, and the output of the motor is connected to the tightness adjustment rod through a coupling.

[0018] Compared with existing technologies:

[0019] 1. By setting a motor to drive the first guide wheel and the second guide wheel to rotate, the friction between the first guide wheel and the second guide wheel can be reduced, thereby preventing the paper from being damaged by friction;

[0020] 2. By setting up a tension adjustment mechanism, when the paper is being conveyed, the paper passes around the tension adjustment rod. At this time, the spring is in a compressed state. Therefore, when the paper is loose, the elastic force of the spring drives the support block and the tension adjustment rod to move, thereby tightening the paper; when the paper is too tight, the paper squeezes the tension adjustment rod, thereby causing the spring to contract, thereby relaxing the paper to avoid being too tight, thereby ensuring the normal conveyance of the paper.
