Description
Technical Field
The utility model relates to the technical field of paper roll processing equipment, in particular to a paper roll sleeve expanding device.
Background
In the current production process of the roll paper, the inner paper core is fixed on the device, and then the paper layer is wound on the paper core through external equipment to form the final product of the roll paper.
Because the inside refill texture is softer, can take place to warp at winding in-process, and current axle is fixed diameter, and its size has unsuitable condition when it inserts in the scroll, and the axle is too thick can lead to the secondary damage of scroll, and the axle is too thin can lead to the scroll not hard up again inconvenient processing on the bead cutter, all needs the manual work to install when the installation axle moreover, and efficiency is lower to lead to the practicality relatively poor.
The patent number CN218931347U of the company relates to an expansion shaft for clamping a paper roll, which can automatically mount a fixed shaft on the paper roll, and improves the mounting and processing efficiency of the paper roll, including the paper roll; still include automatic installation component, automatic installation component includes the workstation, two sets of supports, rise the axle, the backup pad, the meshing cylinder, the division board, driving motor, the shaft coupling, four sets of clamp cylinder and four sets of arc splint, the left and right sides on workstation top all is provided with follows the subassembly, two sets of supports are installed in the left and right sides on workstation top through two sets of follower respectively, rise the axle and install the top at two sets of supports, the scroll suit is on rising the axle, the backup pad is installed in the top left side of workstation, the right-hand member at the backup pad is installed to the meshing cylinder, the output at the meshing cylinder is installed to the division board, driving motor installs the right-hand member at the division board, the left end and the driving motor's of shaft coupling output are connected, the right-hand member of shaft coupling is connected with the left end of rising the axle.
However, the use of tension in the metal members is found to be undesirable in the stage of use, and is desirable for use on rolls because the roll tends to flex somewhat with respect to the metal, and the roll tends to flex somewhat as it is subsequently relaxed by tension, and because of structural limitations, the tension and relaxation strokes cannot be designed to be large, and somewhat insufficient to ultimately unwind the roll, pulling the roll surface, this time with the forced relaxation of the links.
Disclosure of Invention
According to the technical problems, the utility model provides the paper roll sleeve expanding device for preventing the surface of the paper roll from being pulled.
The utility model provides a paper roll sleeve expanding device which is characterized by comprising a left-handed nut, a top sleeve, connecting rods, a right-handed nut and a screw, wherein two sides of one end of the screw are respectively connected with the right-handed nut and the left-handed nut, the upper side and the lower side of the right-handed nut and the upper side and the lower side of the left-handed nut are respectively connected with a plurality of connecting rods, and a plurality of connecting rods are connected with the top sleeve.
Screw rod one end sets up the screw thread, the opposite direction of screw thread.
The connecting rod can rotate around the top sleeve.
The beneficial effects of the utility model are as follows: the utility model relates to a paper roll expanding sleeve device, which is characterized in that a bidirectional screw is regulated, so that the bidirectional screw drives a left nut and a right nut to respectively carry out inward or outward expansion movements, and further the nuts drive a connecting rod connected with the nuts to incline or stand, so that the cost is saved, the purpose of expanding a paper roll can be achieved by simple components, the reasonable stroke design of the expanding and loosening of the time is enough to loosen the paper roll, and the condition of the surface of the paper roll being pulled out during pulling out can be prevented.

Detailed Description
Example 1
The technical scheme of the present utility model will be clearly and completely described in the following with reference to the accompanying drawings.
As shown in fig. 1-2, the utility model provides a paper roll sleeve expanding device, which is characterized by comprising a left-handed nut 1, a top sleeve 2, a connecting rod 3, a right-handed nut 4 and a screw 5, wherein two sides of one end of the screw 5 are respectively connected with the right-handed nut 4 and the left-handed nut 1, the upper side and the lower side of the right-handed nut 4 and the left-handed nut 1 are respectively connected with a plurality of connecting rods 3, and the plurality of connecting rods 3 are connected with the top sleeve 2.
One end of the screw 5 is provided with threads, and the directions of the threads are opposite.
The connecting rod 3 can rotate around the top cover 2.
Example 2
The principle of lever is adopted, and the left-handed screw and the right-handed screw on the same shaft control the connecting rod to jack up the jacking sleeve, so that the purpose of tensioning the paper roll is achieved.
The screw rod 5 is rotated through external tools, and when the screw rod 5 rotates, the screw rod 5 drives the nuts to move towards two ends, the distance between the nuts is 1mm, the distance between the nuts is 18mm, the connecting rod 3 is changed into an upright shape, at the moment, the connecting rod 3 jacks up the top sleeve 2, the outer edge size of the top sleeve 2 is changed from 75mm to 79.56mm as shown in fig. 2, and the inner diameter of a paper tube is generally about 76-78mm, so that the use can be basically satisfied.
When the screw rod 5 is required to be loosened, the connecting rod 3 is forced to be changed into an inclined state from the vertical state by only reversely rotating the screw rod, and the top sleeve 2 is driven to shrink as shown in fig. 1, so that the size is reduced.
The foregoing has shown and described the basic principles and main features of the present utility model and the advantages of the present utility model. The components mentioned in the utility model are common in the prior art, and are provided in the present line
It will be understood by those skilled in the art that the present utility model is not limited to the foregoing embodiments, and that the foregoing embodiments and description are merely illustrative of the principles of this utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, and these changes and modifications fall within the scope of the utility model as hereinafter claimed.
