DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0027] See also Figure 1-5 The utility model provides a technical solution: an adjustable paper roll placement device. It includes a bottom plate 110, on which are mounted a plurality of placement components for fixing paper rolls, on which are mounted a plurality of adjustment components for adjusting the pressure of the placement components, the plurality of placement components and adjustment components are equidistantly arranged, and on which is mounted a driving component for driving the adjustment component;

[0028] The placement assembly includes two groups of blocks 410 and sliders 430. The two groups of blocks 410 are mounted on the bottom plate 110. The two groups of sliders 430 are slidably connected to the bottom plate 110. The two groups of blocks 410 and sliders 430 are symmetrically arranged with the driving assembly as the center. The two groups of blocks 410 are mounted with springs 420. The ends of the two groups of springs 420 away from the blocks 410 are respectively mounted on the two groups of sliders 430. The two groups of sliders 430 are rotatably connected with connecting blocks 440 on the sides away from the springs 420. The two groups of connecting blocks 440 are mounted with baffles 441, which are in an arc-shaped structure. The baffles 441 can be attached to the paper roll through the arc-shaped baffles 441, so as to support the paper roll.

[0029] When placing paper rolls of different sizes, the paper roll presses the baffle 441 to move the baffle 441, and the baffle 441 drives the slider 430 to move. When the paper roll is small, the slider 430 and the baffle 441 move inward due to the elastic force of the spring 420, and the baffle 441 rotates around the pin 432, so that the baffle 441 automatically adapts to the outer diameter of the paper roll, thereby fitting on the outside of the paper roll to support the paper roll. When the paper roll is relatively large, the slider 430 and the baffle 441 compress the spring 420 due to gravity and move to both sides, and the baffle 441 rotates around the pin 432, so that the baffle 441 automatically adapts to the outer diameter of the paper roll, thereby fitting on the outside of the paper roll, so that the paper roll placement device can be automatically adjusted according to the size of the paper roll, thereby improving the flexibility of the paper roll placement device.

[0030] A rotation groove 431 is provided on one side of the slider 430 away from the spring 420, and a pin 432 is installed in the rotation groove 431. The pin 432 is rotatably connected to an end of the connection block 440 away from the baffle 441. By providing the pin 432, the connection block 440 can be rotated on the slider 430, so that when the baffle 441 contacts the outside of the paper roll, the baffle 441 can be adjusted in angle according to the paper roll, so that the baffle 441 fits the outside of the paper roll, thereby improving the stability of the baffle 441 supporting the paper roll.

[0031] The driving assembly includes an adjustment slot 210, which is provided on the bottom plate 110. A worm 220 is rotatably connected in the adjustment slot 210. One end of the worm 220 passes through the outside of the bottom plate 110, and a turning handle 230 is installed at one end of the worm 220. Through the arrangement of the worm 220 and the worm wheel 350, the stopper 410 will not move due to excessive force on the stopper 410 during use, so that the stopper 410 remains stable.

[0032] The adjustment assembly includes two groups of moving grooves 310, both of which are opened on the bottom plate 110, and the two groups of moving grooves 310 are symmetrically arranged with the adjustment groove 210 as the center. The moving grooves 310 are arranged so that the first moving block 360 and the second moving block 370 can move in the moving grooves 310, thereby guiding the first moving block 360 and the second moving block 370 so that the first moving block 360 and the second moving block 370 can only move in a straight line.

[0033] Guide rods 330 are installed in the two groups of moving grooves 310, and threaded rods 320 are rotatably connected in the two groups of moving grooves 310. The two groups of guide rods 330 are respectively above the two groups of threaded rods 320, and the directions of the two groups of threaded rods 320 are opposite. Through the two groups of threaded rods 320 with opposite thread directions, the two groups of first moving blocks 360 can approach and move away from each other during the rotation of the rotating rod 340, so as to facilitate the same adjustment of the pressure of the spring 420, so that the pressure of the spring 340 keeps moving.

[0034] The two groups of guide rods 330 are both slidably connected with a first moving block 360 and a second moving block 370. The two groups of the first moving blocks 360 are respectively threadedly connected to the two groups of threaded rods 320. The two groups of the first moving blocks 360 are respectively installed on the two groups of stoppers 410, and the two groups of the second moving blocks 370 are respectively installed on the two groups of sliders 430. The stoppers 410 and the sliders 430 are moved by the first moving block 360 and the second moving block 370, respectively. At the same time, the first moving block 360 is threadedly connected to the threaded rod 320, so that the first moving block 360 can remain stable during use and is not easy to move. The second moving block 370 can move according to the pressure of the paper roll on the baffle 441, so that the baffle 441 can be attached to the paper roll.

[0035] The adjustment assembly further includes a rotating rod 340, which is rotatably connected in the adjustment slot 210, and the two ends of the rotating rod 340 respectively penetrate into the two groups of moving slots 310, and the two ends of the rotating rod 340 are respectively installed on the two groups of threaded rods 320, and the rotating rod 340 is installed with a worm wheel 350, and the worm wheel 350 is meshed with the worm 220. When adjusting the elastic force of the spring 420, the rotating handle 230 is rotated to drive the worm 220 to rotate, and the rotating rod 340 is driven to rotate under the meshing action of the worm 220 and the worm wheel 350, so that the rotating rod 340 drives the two groups of threaded rods 320 to rotate, and the two groups of threaded rods 320 drive the two groups of first moving blocks 360 to move, so that the two groups of first moving blocks 360 are close to and away from each other, thereby adjusting the elastic force of the two groups of springs 420. It makes it difficult for paper rolls of different weights to have large fluctuations when placed, thereby increasing the stability of the paper roll placing device.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
