[0003] However, the existing adhesive tape take-up and pay-off equipment has the following main problems: as the production demand changes, the take-up and pay-off speed of the adhesive tape will be adjusted accordingly, but the traditional take-up and pay-off assembly often lacks an effective mechanism to adapt to such speed changes in real time, making it difficult to maintain a constant tension level of the adhesive tape; too tight adhesive tape can cause breakage or damage, while too loose can affect the quality or efficiency of subsequent processing; therefore, it is particularly important to develop a take-up and pay-off assembly that can automatically adjust the tension of the adhesive tape. CONTENT OF THE UTILITY MODEL
[0004] The problem to be solved by the present application is that the existing adhesive tape take-up and pay-off equipment cannot achieve self-adaptive adjustment of tension, so that the adhesive tape is difficult to maintain an adaptive tension state after the take-up and pay-off speed is adjusted.
[0005] To solve the above technical problems, the application provides a self-tightening take-up and pay-off assembly for adhesive tape, which comprises a rack, symmetrical vertical columns are arranged on the upper part of the rack, a roller around which the adhesive tape is wound is transversely arranged on the upper part of the vertical column, the roller is installed on the vertical column through a bearing, a driving assembly for driving the roller to rotate for winding operation is arranged on the upper part of the vertical column, a pay-off assembly capable of driving the adhesive tape for pay-off operation is also arranged on the upper part of the rack, and a tensioning assembly capable of self-adaptively adjusting the tightness of the adhesive tape is also arranged on the upper part of the rack, the tensioning assembly can automatically adjust the position according to the tensioning state of the adhesive tape, and a guide assembly for reversing guiding operation of the adhesive tape is arranged between the roller and the tensioning assembly.
[0006] Since the self-tightening take-up and pay-off assembly of the present application is designed with a driving assembly, a pay-off assembly, a tensioning assembly and a guide assembly, it can not only realize the take-up and pay-off operation of the adhesive tape through the driving assembly and the pay-off assembly, but also realize the self-adaptive tensioning of the adhesive tape and the reversing guiding operation in the take-up and pay-off process through the tensioning assembly and the guide assembly, thereby solving the problem that the existing adhesive tape take-up and pay-off equipment cannot achieve self-adaptive adjustment of tension, so that the adhesive tape is difficult to maintain an adaptive tension state after the take-up and pay-off speed is adjusted.
