Description

Technical Field

[0001] The utility model relates to the technical field of lining paper, and in particular to a device for copper belt lining paper. Background Art

[0002] In recent years, with the rapid development of the electronics industry, the demand for electroplating tapes and electronic copper tapes has increased, and the quality requirements have also become higher and higher, especially the surface quality of the tape rolls. Now, general customers require that no small pits or other spots are allowed on the surface when the tape is magnified 200 times. In addition to the on-site process hygiene and equipment maintenance, these surface defects are mainly caused by the scratches during the copper tape lifting process and the scratches during the unwinding process of each process. Through production tests, it was found that the finished lining paper has a very obvious effect on solving such scratches. The existing lining paper device is driven by a motor to rotate the reel, which is a pneumatic expansion type used to lock the paper reel, and its speed is automatically synchronized with the reel speed of the unwinding machine. The spacing between the reels cannot be adjusted, and the versatility for copper tapes of different sizes is poor. When the motor fails, the reel stops rotating, while the copper tape continues to rotate, which will tear the lining paper, and the copper tape needs to be rolled up again and re-lined, which increases production costs and reduces production efficiency.

[0003] After searching, the applicant found that the Chinese patent document with publication number 208631751U disclosed a transformer copper strip or aluminum strip roll lining paper conveying device on March 22, 2019, which includes a base, a sliding seat, a screw, a bracket and at least two paper feed shafts; the sliding seat is connected to the base in a sliding fit; the screw is installed on the base through a bearing seat, and is formed into a screw transmission mechanism through a nut installed on the sliding seat; the bracket is installed on the sliding seat; and the paper feed shaft frame is placed on the bracket.

[0004] The device cannot perform backing paper work on copper strips of different sizes at the same time. Utility Model Content

[0005] The utility model aims to provide a copper belt lining paper device which can realize lining paper work on copper belts of different sizes at the same time.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a copper belt lining paper device, including a mounting shaft; the mounting shaft is respectively provided with an adjustment structure and a paper tube; the paper tube is connected to the adjustment structure.

[0010] The paper tubes are respectively arranged on both sides of the baffle; and the end of the second fixing pin is pressed against the baffle.

[0011] A top plate is provided on a side of the side baffle away from the first fixing pin; the top plate presses the side baffle against the end of the first fixing pin.

[0012] The top plate comprises a sleeve and a pressing plate; the sleeve is sleeved on the mounting shaft; the pressing plate is arranged at the end of the sleeve and pressed against the side baffle.

[0013] A shaft clamp is provided on one side of the sleeve away from the pressing plate; the shaft clamp is sleeved on the mounting shaft and tightly pressed against the end of the sleeve.

[0014] The shaft clamp is provided with a bolt hole, and a locking bolt is connected in the bolt hole.

[0015] A fixing seat is arranged on the installation shaft; the fixing seat is connected to the workbench.

[0016] The beneficial effects of this application are:

[0017] The mounting shaft is fixedly mounted on the workbench through a fixing seat; the adjusting structure comprises a fixing pin; the fixing pin is respectively inserted into the mounting tube from both sides of the paper tube; the fixing pin and the mounting tube are fixedly connected by interference fit; a connecting hole is provided on the fixing pin, which is sleeved on the mounting shaft; the fixing pin and the mounting shaft are clearance-fitted, thereby achieving that the fixing pin and the paper tube rotate together on the mounting shaft;

[0018] The fixing pin can slide freely on the installation, so that the distance between the first fixing pin and the second fixing pin can be flexibly adjusted, and paper tubes of lining paper of different sizes can be installed to achieve lining paper for copper strips of different sizes, which effectively improves the versatility of the device; at the same time, multiple baffles are installed on the installation shaft, and paper tubes are installed on both sides of the baffles, so that the paper lining operation for multiple groups of copper strips can be achieved at the same time, which greatly improves the production efficiency;

[0019] First, install the first fixing pin and the second fixing pin in the installation tube of the paper tube; then install the side baffle on one side of the first fixing pin; install the top plate and the shaft clamp in sequence on the side of the side baffle away from the first fixing pin; install the baffle to separate adjacent paper tubes; first pre-tighten the shaft clamp on the installation shaft, adjust the distance between the shaft clamp and the top plate, and the top plate presses the side baffle tightly, so that the side baffle provides appropriate pressure on the first positioning pin, and generates tension through the friction resistance between the side baffle and the positioning pin to prevent the lining paper from wrinkling; after the adjustment is completed, tighten the locking bolt; at this time, connect the end of the lining paper on the paper tube to the copper belt, and the movement of the copper belt can drive the movement of the lining paper to realize the work of the copper belt lining paper;

[0020] Compared with the solution of using an independent motor to drive the paper drum to rotate, when the paper drum motor or the copper belt motor fails, the rotation speeds of the two motors will be different; this will cause the lining paper to break, and the copper belt needs to be rolled back and relined, which greatly increases the production burden; the paper drum of the present device can rotate flexibly on the mounting shaft, and the copper belt is used to drive the lining paper to move, so that the movement state of the lining paper and the copper belt can always be kept consistent. Even if the copper belt motor fails, the lining paper can avoid breaking, and no additional workload will be imposed on the staff. BRIEF DESCRIPTION OF THE DRAWINGS
