Description

Technical Field

[0001] This utility model belongs to the field of paper roll fixing technology, and in particular relates to a paper roll fixing device for printing plants. Background Technology

[0002] In the printing industry, paper rolls are a crucial raw material. They are made from natural fibers such as wood pulp and straw pulp, or with the addition of chemical fibers, and then wound onto a paper core according to specific specifications. This regular cylindrical design not only facilitates efficient use of space but also reduces transportation and storage costs. With the addition of outer packaging, it can play a role in preventing moisture and damage, effectively extending the shelf life.

[0003] However, paper rolls are usually heavy, large, and cylindrical, making them very easy to roll during transportation. Existing paper roll fixing devices are mostly non-adjustable wooden frames. Using these wooden frames for fixing is not only difficult to adapt to paper rolls of different sizes, but also easy to leave deep indentations on the surface of the paper roll during transportation, or even cause damage, affecting the quality of the paper roll.

[0004] To address these issues, we provide a paper roll fixing device for printing plants. Utility Model Content

[0005] The purpose of this invention is to provide a paper roll fixing device for printing plants. By rotating the first handwheel to adjust the distance between the two bottom frames, and then by rotating the second handwheel to adjust the curvature of the flexible plate, the problem of the inconvenience of storing and transporting paper rolls in existing printing plants is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a paper roll fixing device for a printing plant, comprising a base frame, two parallel sliding plates fixedly connected to the top of the base frame, two sliding grooves parallel to the two sides respectively opened inside the base frame, and a support component provided inside each of the two sliding grooves; two opposing sliding frames, each including a bottom frame above the base frame, with two slide rails fixedly connected to the bottom of the bottom frame and slidably connected inside the two sliding plates respectively; a fixed frame fixedly connected to one edge of the top of the base frame, and two support rods rotatably connected to the other edge of the top of the base frame; a flexible plate fixedly connected to the top of the fixed frame, with an upper crossbar fixedly connected to the back of the flexible plate near the top, and the free ends of the two support rods rotatably connected to the interior of the upper crossbar; a fixed rod fixedly connected to the bottom center of the bottom frame; and an arc adjustment component provided on the back of the flexible plate; and an adjustment component including two mounting seats fixedly connected to the top of the base frame, with a bidirectional screw rotatably connected inside the two mounting seats, and two fixed rods threadedly sleeved onto the two threaded portions of the bidirectional screws respectively, with a first handwheel fixedly connected to both ends of the bidirectional screws.

[0008] The present invention is further configured such that the support component includes a support frame movably fitted inside the sliding groove, and through holes are provided on both sides of the base frame. Fixing bolts are movably fitted inside the through holes. The support frame has upper and lower screw holes that are collinear, and both the upper and lower screw holes are adapted to the fixing bolts.

[0009] The present invention is further configured such that a base plate is fixedly connected to the bottom of the support frame, and a rubber pad is fixedly connected to the bottom of the base plate.

[0010] The present invention is further configured such that the curvature adjustment component includes a central crossbar fixedly connected to the middle of the back of the flexible board and two sleeves rotatably connected to the top of the bottom frame. Two symmetrical sliding rods are rotatably connected inside the central crossbar, and the other ends of the two sliding rods are respectively movably sleeved inside the two sleeves. A connecting rod is fixedly connected between the two sleeves. A threaded sleeve is rotatably connected to the middle of the connecting rod. A second handwheel is fixedly connected to the outside of the threaded sleeve. An adjusting screw threaded inside the threaded sleeve is rotatably connected to the middle of the central crossbar.

[0011] The present invention is further configured such that pull rings are rotatably connected to the top of both upper crossbars, and a fixing strap for further securing the paper roll is tied between the two pull rings.

[0012] The present invention is further provided that omnidirectional wheels are fixedly connected to the four corners of the bottom of the base frame.

[0013] The present invention is further configured such that buffer pads are fixedly connected to the opposite sides of the two flexible boards.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model rotates the first handwheel to drive the bidirectional screw to rotate, and then moves the two bottom frames through the two fixed rods until they match the diameter of the paper roll to be fixed. Then, the second handwheel is rotated to drive the threaded sleeve to rotate. Then, under the action of the thread, the adjusting screw moves inside the threaded sleeve. Then, the middle crossbar can drive the middle part of the flexible plate to move, thereby realizing the adjustment of the curvature of the flexible plate according to the paper roll to be fixed, so as to make the paper roll more stable and at the same time disperse the pressure and reduce the indentation on the surface of the paper roll.

[0016] 2. The four universal wheels of this utility model make it easier to move the paper roll over short distances. By removing the fixing bolts and lifting the base frame so that the through hole is aligned with the screw hole, the universal wheels are suspended in the air, which makes the paper roll more stable when transporting it over long distances.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0025] Please see Figures 1 to 4This utility model is a paper roll fixing device for a printing plant, including a base frame 100. Two parallel sliding plates 103 are fixedly connected to the top of the base frame 100. Two sliding grooves 101, each parallel to one of the two sides, are formed inside the base frame 100. Each sliding groove 101 contains a support assembly 400. Two opposing sliding frames 200 include a base frame 201 located above the base frame 100. Two slide rails 202, each slidably connected to the bottom of the base frame 201, are fixedly connected to the bottom of the base frame 201. A fixing frame 203 is fixedly connected to one edge of the top of the base frame 100, and two support rods 204 are rotatably connected to the other edge of the top of the base frame 100. A flexible plate 207 is fixedly connected to the top of the fixing frame 203. The back of the flexible plate 207 is close to... A top crossbar 205 is fixedly connected to the top, and the free ends of the two support rods 204 are rotatably connected to the inside of the top crossbar 205. A fixing rod 206 is fixedly connected to the bottom center of the bottom frame 201. An arc adjustment component 500 is provided on the back of the flexible plate 207. The distance adjustment component 300 includes two mounting seats 301 fixedly connected to the top of the base frame 100. A bidirectional screw 302 is rotatably connected inside the two mounting seats 301, and the two fixing rods 206 are respectively threaded onto the outside of the two threaded parts of the bidirectional screw 302. A first handwheel 303 is fixedly connected to both ends of the bidirectional screw 302. By rotating the first handwheel 303, the bidirectional screw 302 is driven to rotate, thereby adjusting the distance between the two sliding frames 200 according to the diameter of the paper roll, thus ensuring the stability of the paper roll.

[0026] Specifically, the curvature adjustment component 500 includes a central crossbar 501 fixedly connected to the middle of the back of the flexible plate 207 and two sleeves 502 rotatably connected to the top of the bottom frame 201. Two symmetrical sliding rods 503 are rotatably connected inside the central crossbar 501, and the other ends of the two sliding rods 503 are respectively movably sleeved inside the two sleeves 502. A connecting rod 504 is fixedly connected between the two sleeves 502. A threaded sleeve 505 is rotatably connected to the middle of the connecting rod 504. A second handwheel 506 is fixedly connected to the outside of the threaded sleeve 505. An adjusting screw 507 threaded inside the threaded sleeve 505 is rotatably connected to the middle of the central crossbar 501. By rotating the second handwheel 506 to drive the threaded sleeve 505 to rotate, the curvature of the flexible plate 207 can be adjusted, so that the flexible plate 207 can fit more closely to the outside of the paper roll, further ensuring the stability of the paper roll fixation, while also dispersing pressure and reducing indentations on the surface of the paper roll.

[0027] Furthermore, buffer pads 208 are fixedly connected to the opposite sides of the two flexible boards 207.

[0028] The operation process of this embodiment is as follows: When it is necessary to fix the paper roll, firstly, the first handwheel 303 is rotated to drive the bidirectional screw 302 to rotate. Then, the two fixed rods 206 drive the two bottom frames 201 to move until they match the diameter of the paper roll to be fixed. Then, the second handwheel 506 is rotated to drive the threaded sleeve 505 to rotate. Then, under the action of the thread, the adjusting screw 507 moves within the threaded sleeve 505. Then, the middle crossbar 501 can drive the middle part of the flexible plate 207 to move, thereby realizing the adjustment of the curvature of the flexible plate 207 according to the paper roll to be fixed, so as to make the paper roll more stable and at the same time disperse the pressure and reduce the indentation on the surface of the paper roll. Example 2

[0029] Please see Figure 1 and Figure 3 Based on the first specific embodiment, the support assembly 400 includes a support frame 401 that is movably sleeved inside the sliding groove 101. Both sides of the base frame 100 are provided with through holes 404. Fixing bolts 405 are movably sleeved inside the through holes 404. The support frame 401 is provided with upper screw holes 406 and lower screw holes 407 that are collinear, and both upper screw holes 406 and lower screw holes 407 are adapted to the fixing bolts 405. Universal wheels 102 are fixedly connected to the four corners of the bottom of the base frame 100. The four universal wheels 102 make it easier for the operator to move the paper roll over short distances.

[0030] Specifically, a base plate 402 is fixedly connected to the bottom of the support frame 401, and a rubber pad 403 is fixedly connected to the bottom of the base plate 402.

[0031] The operation process of this embodiment is as follows: when it is necessary to place the paper roll stably, first remove the fixing bolt 405, then lift the base frame 100 upward so that the through hole 404 is aligned with the screw hole 406, thereby suspending the caster wheel 102 in the air, which can make the paper roll more stable when transporting it over long distances. Example 3

[0032] Please see Figure 1 and Figure 2 Based on specific embodiments one and two, pull rings 600 are rotatably connected to the top of the two upper crossbars 205, and a fixing strap 700 for further fixing the paper roll is tied between the two pull rings 600.
