Abstract

This utility model discloses a tape rewinding device with a tape changing mechanism, including a base, a central rotating shaft on the base, connecting arms symmetrically arranged on both sides of the central rotating shaft, a take-up shaft at the top of each connecting arm, a take-up drum sleeved on the take-up shaft, and support arms symmetrically arranged on the central rotating shaft perpendicular to the connecting arm direction. Each support arm has a support shaft at its end, and a transition roller is sleeved on the support shaft.

Description

Roll changing mechanism of tape winding device

technical field

The utility model relates to a tape rewinding device, in particular to a roll changing mechanism of the tape rewinding device.

Background technique

Chinese utility model patent CN201849984U discloses an assembly line for adhesive tape production. Its equipment includes a traction mechanism, a coating mechanism, a laminating mechanism and a winding mechanism. There is only one winding shaft in the tape winding mechanism. Downtime is required to allow workers to remove the finished tape roll and replace it with a new paper core on the take-up spool. Later, people designed a rotary rewinding device. Connecting arms were symmetrically arranged on both sides of the central rotating shaft. The rewinding shafts take up the tape alternately. During normal rewinding, one of the rewinding shafts is at the winding position to take up the tape, and the other reeling shaft is at the unloading position; when changing rolls, the roll changing mechanism rotates, and the tape has been taken The winding shaft rotates 180° to reach the unloading position, while the uncoiled winding shaft rotates to the winding position. After changing the station, the winding shaft with the newly installed paper core tube is rewound, and then transferred to the unloading position. The rewinding shaft at the third position carries out the process of unloading the finished tape roll and installing a new paper core tube. In this way, the rotary winding device does not need to stop when changing rolls, which ensures continuous operation of the production line and improves production efficiency. However, when the above-mentioned rotary winding device is changing rolls, the winding shaft that has already taken up the tape drives the tape to rotate 180° to the unloading position. During this process, the tape is easily stuck to the central shaft, affecting the normal operation of the equipment, and even cause unnecessary downtime. Therefore, it is necessary to further improve the existing roll changing mechanism.

Contents of the invention

The purpose of the invention of this utility model is to provide a roll change mechanism for tape winding device, which can prevent the tape from sticking to the central shaft during roll change, ensure the normal operation of the equipment, and avoid unnecessary shutdown.

In order to achieve the purpose of the above invention, the technical solution adopted by the utility model is: a roll changing mechanism of an adhesive tape winding device, including a base, the base is provided with a central rotating shaft, and connecting arms are symmetrically arranged on both sides of the central rotating shaft, so that The top of the connecting arm is provided with a rewinding shaft, the rewinding shaft is covered with a rewinding cylinder, the central shaft is symmetrically provided with a support arm perpendicular to the direction of the connecting arm, and the end of the support arm is provided with a support shaft. A transition roller is sheathed on the supporting shaft.

In the above technical solution, a paper core winding drum is sleeved on the winding shaft.

In the above technical solution, the width of the transition roller is consistent with the width of the tape.

In the above technical solution, one of the rewinding shafts is located at the coiling position to take up the adhesive tape, and the other reeling shaft is located at the unloading position. When changing rolls, the reeling mechanism rotates 180° around the central shaft, and the rewinding of the tape that has been taken up The reel rotates to the unloading position, and the uncoiled reel rotates to the take-up position. The tape transitions from the reel that has been reeled to the reel that has not been reeled through the transition roller. The winding reel is rewound, and the rewinding reel transferred to the unloading station is used for the process of unloading the finished tape roll and installing a new reel.

Due to the application of the above-mentioned technical solutions, the utility model has the following advantages compared with the prior art:

The utility model is symmetrically provided with transition rollers which play an excessive role on both sides of the central rotating shaft, which can prevent the adhesive tape from sticking to the central rotating shaft when changing rolls, ensure the normal operation of the equipment, and avoid unnecessary downtime.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Embodiment 1: Referring to Figures 1 and 2, a roll changing mechanism of an adhesive tape winding device includes a base 1, the base is provided with a central rotating shaft 2, and connecting arms 3 are symmetrically provided on both sides of the central rotating shaft, so that The top of the connecting arm is provided with a rewinding shaft 4, the rewinding shaft is covered with a rewinding drum 5, the reeling drum is a paper core tube, and the central rotating shaft is symmetrically provided with a support arm 6 perpendicular to the direction of the connecting arm. A support shaft 7 is provided at the end of the support arm, and a transition roller 8 is sheathed on the support shaft, and the width of the transition roller is consistent with the width of the adhesive tape.

When the utility model is in operation, one of the rewinding shafts is located at the coiling position to take up the adhesive tape, and the other reeling shaft is located at the unloading position. When changing rolls, the reeling mechanism rotates 180° around the central shaft, and the tape has been rolled up. The reel rotates to the unloading position, and the reel that has not yet been rolled turns to the take-up position. The tape transitions from the reel that has been reeled through the transition roller to the reel that has not been reeled. The coiled reel is coiled, and the reel transferred to the unloading station is unloaded and installed with a new reel.
