Description

Technical Field

[0001] The utility model relates to the technical field of accessories of a powder shaking machine, in particular to a cloth receiving device capable of tension control. Background Art

[0002] The cloth receiving device is arranged at the end of the powder shaking machine and is closely connected to the drying chamber of the powder shaking machine. After the PET film is dried in the drying chamber, the cloth receiving device winds the cooled printed product onto the cloth receiving roller. The flowing time of a certain small section of the PET film in the drying chamber is inversely proportional to the drying speed of the drying chamber. However, the drying speed of the drying chamber is also related to the density of the printed text and pattern; the greater the density of the printed text and pattern, the slower the drying speed of the drying chamber; therefore, the drying speed of the drying chamber is variable. The cloth receiving speed of the existing cloth receiving device is constant and always in a working state; thus, two disadvantages occur: Disadvantage 1, the PET film is uneven in thickness due to excessive pulling by the cloth receiving device, affecting the quality of the printed product; Disadvantage 2, the motor of the cloth receiving device fails or is scrapped more frequently due to idle consumption. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above problems and provide a cloth receiving device capable of tension control.

[0006] The cloth receiving component includes a cloth receiving roller, a left main spindle box, a right main spindle box, and a cloth receiving motor for driving the cloth receiving roller to rotate; the cloth receiving motor is installed in the left main spindle box; the ends of the cloth receiving roller penetrate through the left main spindle box and the right main spindle box and are respectively rotatably connected to the left main spindle box and the right main spindle box;

[0007] After the PET film passes around the lower part of the tension roller, it is connected to the upper part of the cloth receiving roller. The PET film lifts the tension roller; on one side of the tension roller, the PET film connected to the cloth receiving roller is subjected to the tension from the cloth receiving roller; on the other side of the tension roller, the PET film is subjected to the tension from the drying chamber; the tension from the drying chamber can be from the drying chamber mesh belt; the drying chamber mesh belt in the prior art has a built-in negative pressure suction force, which can suck the PET film tightly; as the drying chamber rotates forward and the cloth receiving motor stops, the tension roller descends; when the tension roller descends to a certain extent, the end of the tension roller triggers the photoelectric sensor, which can start the cloth receiving motor; when the cloth receiving motor starts, it drives the cloth receiving roller to rotate; the rotating cloth receiving roller tightens the PET film, which can lift the tension roller until the end of the tension roller no longer triggers the photoelectric sensor. In this way, the cloth receiving motor can adapt to the drying speed of the drying chamber. Only when a part of the PET film rotates out of the drying chamber does the cloth receiving motor start. After the cloth receiving roller tightens a part of the PET film, the cloth receiving motor stops again, which can avoid the idle consumption of the cloth receiving motor, protect the cloth receiving motor, and prevent the PET film from being overstretched.

[0008] Preferably, the tension assembly further includes a vertical rack and a lifting gear; the vertical rack is installed on one side of the vertical groove; the lifting gear is coaxially fixed to the end of the tension roller and meshes with the vertical rack; the cooperation between the lifting gear and the vertical rack enables the two ends of the tension roller to lift synchronously, ensuring the smooth flow of the PET film.
