Description

Technical Field

[0001] The utility model relates to the technical field related to paper tube production and processing, in particular to a roll cutting machine used for paper production. Background Art

[0002] After the paper roll is completed, it needs to be cut by a cutting machine. In order to ensure that the lengths of each paper roll are equal, most existing cutting machines use a propulsion mechanism to propel the paper roll at a fixed distance. In combination with a cutting knife, the paper roll can be cut at a fixed distance. However, the method of propulsing the paper roll by the propulsion mechanism requires the setting of a precise numerical control system, which obviously increases the equipment cost and the subsequent maintenance and maintenance costs. In addition, when in use, it requires professional personnel to control it, which undoubtedly has a major defect. For this reason, we propose a roll cutting machine for paper production.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides a technical solution: a roll cutting machine for paper production, comprising a first feed drum 1 and a second feed drum 10, wherein the first feed drum 1 is plugged and installed on the upper side of the second feed drum 10, and the first feed drum 1 and the second feed drum 10 are respectively provided with a first cutting groove 11 and a second cutting groove 12 on their peripheries, and a cutting knife 21 and a baffle plate 22 are respectively rotatably installed on the peripheries of the first feed drum 1 and the second feed drum 10, and the cutting knife 21 is arranged in the first cutting groove 11, The baffle plate 22 is arranged inside the baffle plate 22, the cutting knife 21 and the baffle plate 22 are both arranged in a semicircular shape, and the cutting knife 21 and the baffle plate 22 are staggered with each other, and a first motor 2 is fixedly installed on the periphery of the first feeding cylinder 1, and the lower end of the first motor 2 is fixedly connected to the rotating shaft of the upper end of the cutting knife 21 through its output shaft, and a limiting plug rod 24 is fixedly installed on the rotating shaft of the lower end of the cutting knife 21, and a limiting sleeve 23 connected to the limiting plug rod 24 is fixedly installed on the upper end of the baffle plate 22 through its output shaft.

[0023] Working principle: When in use, insert the paper tube into the upper end of the first feeding tube 1, and the paper tube itself will drop into the second feeding tube 10 by its own weight;

[0024] The first motor 2 is started, and the limiting plug sleeve 23 is plugged into the limiting plug rod 24, so that the first motor 2 can drive the cutting knife 21 and the material blocking plate 22 to rotate in the first cutting groove 11 and the second cutting groove 12 respectively through its output shaft. Since the cutting knife 21 and the material blocking plate 22 are both semicircular, and the two are staggered with each other;

[0025] When the baffle plate 22 rotates to the inside of the second feed cylinder 10, the cutting knife 21 and the first feed cylinder 1 are separated from each other, so that the baffle plate 22 can block the paper tube inside the second feed cylinder 10; when the cutting knife 21 rotates into the inside of the first feed cylinder 1, the paper tube blocked by the baffle plate 22 can be cut, and as the cutting knife 21 rotates, the baffle plate 22 is separated from the second feed cylinder 10, so that the cut paper tube can be discharged downward from the second feed cylinder 10, completing the discharge.

[0026] As a further description of the above technical solution: a first limit seat 241 fixedly connected to the first feed cylinder 1 is provided on the outer side of the first cutting groove 11, and the cutting knife 21 is rotatably installed in the first limit seat 241; a second limit seat 231 fixedly connected to the second feed cylinder 10 is provided on the outer side of the second cutting groove 12, and the baffle plate 22 is rotatably installed in the second limit seat 231.

[0027] Specifically, the first limit seat 241 and the second limit seat 231 are provided to limit the movement direction of the cutting blade 21 and the baffle plate 22, so that the cutting blade 21 and the baffle plate 22 can stably rotate inside and outside the first cutting groove 11 and the second cutting groove 12 respectively.

[0028] As a further description of the above technical solution: a plurality of first limit plates 13 are fixedly installed at equal intervals at the lower end of the first feed cylinder 1, a plurality of second limit plates 14 are fixedly installed at the upper end of the second feed cylinder 10, and adjacent first limit plates 13 and second limit plates 14 are plugged into each other; fixed seats 15 are respectively fixedly installed on both sides of the outer periphery of the first feed cylinder 1, the first motor 2 is fixedly installed on the upper end of the fixed seat 15 on one side, and the second motor 3 is fixedly installed on the upper end of the fixed seat 15 on the other side; a limiting sleeve 31 is fixedly installed on the outer periphery of the first feed cylinder 1, a threaded sleeve 32 plugged into the lower end of the inner cavity of the limiting sleeve 31 is fixedly installed on the outer periphery of the second feed cylinder 10, and a threaded rod 33 threadably connected to the threaded sleeve 32 is fixedly installed on the lower end of the second motor 3 through its output shaft.

[0029] When the cutting length of the paper roll needs to be adjusted, the second motor 3 is started, and the threaded rod 33 is driven to rotate through its output shaft. The limiting sleeve 31 is connected to the threaded sleeve 32 through the plug connection, and the movement direction of the threaded sleeve 32 is restricted, so that the rotating threaded rod 33 can drive the second feeding cylinder 10 to move up and down at the lower side of the first feeding cylinder 1 through the threaded connection between the threaded sleeve 32 and the second feeding cylinder 10, so that the distance between the cutting knife 21 and the baffle plate 22 can be adjusted to achieve the effect of adjusting the cutting length.

[0030] Through the plug-in connection between the first limiting plate 13 and the second limiting plate 14, when the first feeding cylinder 1 and the second feeding cylinder 10 are contracted or expanded, the gap generated by the movement of the two can be supplemented, so as to achieve the effect of limiting the paper tubes inside the two and prevent the paper tubes from deviating outwards;

[0031] Through the plug-in connection between the limiting sleeve 23 and the limiting rod 24, when the cutting knife 21 and the material baffle plate 22 move toward or away from each other, the two can always be connected to each other, so that the first motor 2 can drive the cutting knife 21 and the material baffle plate 22 to rotate through its output shaft.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
