Abstract
Description
Technical Field
[0001] The utility model relates to a roll position transverse shifting mechanism for a roll paper reel, belonging to the technical field of flexographic printing machine applications. Background Art
[0002] In the field of flexographic printing machine application technology, a turret-type reel is required in the printing process. The turret-type reel uses an air core as a reel to roll paper, and the paper roll is fixed to the machine through the air core. However, when the paper is rolled up by the air core, the axial position of the air core cannot be adjusted, which is not convenient for realizing the lateral movement of the paper roll, and thus cannot flexibly adapt to the printing process; in addition, as the width of the machine increases, the use of traditional air shafts has many disadvantages. The larger the width of the machine, the longer the air shaft used, which is not easy to pass through the paper core, and the risk of the air shaft breaking will increase during high-speed operation.
[0003] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A roll paper reel position transverse movement mechanism comprises two parallel wall panels, guide rollers are rotatably mounted at both ends of the two wall panels, and a fixed bracket is symmetrically mounted on the opposite outer sides of the two wall panels;

The cylinder pushes the sliding frame to move inward, so that the movable plate pushes the transverse movement mechanism to move inward, driving the chuck to move inward.
[0012] Furthermore, the transverse movement mechanism also includes a sleeve sleeved on the outside of the transmission shaft, a positioning block is fixedly provided axially inside the sleeve, a sliding groove is provided axially on the transmission shaft, the positioning block slides in cooperation with the sliding groove so that the transmission shaft slides in the sleeve, and a shell is rotatably mounted on the outside of the sleeve through a bearing, one end of the transmission shaft is rotatably mounted on the movable plate, and a chuck is fixedly mounted on the other end.
[0013] Furthermore, a sprocket is sleeved on the outer side of the sleeve, and the sprocket is driven by a chain transmission mechanism. The rotation of the sprocket drives the transmission shaft to rotate, thereby driving the chuck to rotate.
[0014] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:
[0015] The cylinder on the left side pushes the sliding frame to move inward, so that the moving plate pushes the transverse movement mechanism to move inward, driving the clamps to move inward, so that the two clamps clamp the paper roll; a lead screw is rotatably installed on the fixed plate of the fixed bracket on the right side, and when the lead screw rotates, it pulls the moving plate to move, and the moving plate pulls the transverse movement mechanism to move, and the transverse movement mechanism and its corresponding clamps move laterally, thereby realizing the transverse movement of the paper roll between the two clamps, and tightening the two ends of the paper roll through the two clamps.

[0023] A lead screw 14 is rotatably mounted on the fixed plate 4 of the fixed bracket on the right side, and the sliding frame includes two sliding sleeves 7 that are respectively slidably matched with two sliding rods 5 and a movable plate 6, and the movable plate 6 connects the two sliding parts. A nut is fixed on the movable plate 6, and the nut is rotatably matched with the lead screw 14. The lead screw 14 is fixedly connected to the synchronous wheel 13, and the synchronous wheel 13 is driven by the driving motor 12.
[0024] The outer end of the transverse movement mechanism transmission shaft 801 is rotatably mounted on the movable plate 6. When the lead screw 14 rotates, it pulls the movable plate 6 to move, and the movable plate 6 pulls the transverse movement mechanism 8 to move, thereby pulling the corresponding clamp 9 to move laterally, thereby achieving the translation of the paper roll between the two clamps 9.
[0025] A cylinder 10 is installed on the fixed plate 4 of the fixed bracket on the left side. The telescopic rod of the cylinder 10 is fixedly connected to the movable plate 6 of the sliding frame on this side. The cylinder 10 pushes the sliding frame to move inward, so that the movable plate 6 pushes the transverse movement mechanism 8 to move inward, driving the clamp 9 to move inward, so that the two clamps 9 clamp the paper roll roller.
[0026] The transverse movement mechanism 8 also includes a sleeve 802 sleeved on the outside of the transmission shaft 801, a positioning block 804 is fixedly provided axially inside the sleeve 802, a sliding groove 803 is provided axially on the transmission shaft 801, the positioning block 804 slides with the sliding groove 803, so that the transmission shaft 801 slides in the sleeve 802, and a housing 805 is rotatably installed on the outside of the sleeve 802 through a bearing, one end of the transmission shaft 801 is rotatably installed on the movable plate 6, and the other end is fixedly installed with a chuck 9.
[0027] A sprocket 11 is sleeved on the outer side of the sleeve 802. The sprocket 11 is driven by a chain transmission mechanism (not shown in the figure). The rotation of the sprocket 11 drives the transmission shaft 801 to rotate, thereby driving the clamping head 9 to rotate, thereby driving the paper roll roller to rotate.
[0028] The specific working principle of the utility model:
[0029] When clamping, the telescopic rod of the left cylinder 10 is fixedly connected to the moving plate 6 of the sliding frame on this side, and the cylinder 10 pushes the sliding frame to move inward, so that the moving plate 6 pushes the transverse mechanism 8 to move inward, driving the clamping head 9 to move inward, so that the two clamping heads 9 clamp the paper roll roller.
[0030] During transverse movement, a lead screw 14 is rotatably installed on the fixed plate 4 of the fixed bracket on the right side, and the outer end of the transverse movement mechanism transmission shaft 801 is rotatably installed on the movable plate 6. When the lead screw 14 rotates, it pulls the movable plate 6 to move, and the movable plate 6 pulls the transverse movement mechanism 8 to move. The transverse movement mechanism 8 and its corresponding chuck 9 move laterally, thereby realizing the transverse movement of the paper roll roller between the two chucks 9.
[0031] When the paper roll is rotating, a sprocket 11 is sleeved on the outer side of the sleeve 802. The rotation of the sprocket 11 drives the transmission shaft 801 to rotate, thereby driving the clamp 9 to rotate, thereby driving the paper roll to rotate.
[0032] The two ends of the paper roll are tightened by two clamps 9, and an air-expanding mandrel is not required, thereby avoiding various faults caused by the air-expanding mandrel, and the lateral position of the paper roll can be flexibly adjusted.
