Description

Technical Field

[0001] This utility model belongs to the field of electronic tape processing technology, and relates to a film chuck take-up roller. Background Technology

[0002] In the processing of electronic tape, the winding of materials and semi-finished products is achieved by rotating the winding roller. Before winding, the "cloth end" of the material to be wound needs to be fixed on the winding roller. In the existing method, the "cloth end" is usually fixed to the winding circumference of the winding roller with tape. This method is not only inconvenient to operate, but also makes it difficult to ensure the flatness of the film to be wound, which can easily cause obvious wrinkles in the first part of the material to be wound, resulting in material waste and wasted winding space. Finally, the adhesion of the tape is also poor, and it is easy to fall off when the winding roller starts, affecting the operation. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a film chuck take-up roller. The technical problem to be solved by this invention is how to achieve rapid clamping and positioning of the film on the take-up roller.

[0004] The objective of this utility model can be achieved through the following technical solution: a film chuck take-up roller, characterized in that it includes a roller and two limiting end plates located at both ends of the roller. The roller has an installation groove parallel to the roller axis. A clamping plate is rotatably connected in the installation groove. The clamping plate is rotatably connected to the two limiting end plates by a pin. The clamping plate includes a pressing part located on one side of the pin and a locking part located on the other side of the pin. The side wall of the installation groove is adapted to the locking part. The end of the locking part has a check bend. The check bend and the locking part are connected by an elastic element.

[0005] Furthermore, the card plate is made of rubber, and the check bend, locking part, pressing part and elastic element are integrally formed.

[0006] When fixing the head of the film to be rolled, first flip the clamping plate so that the locking part is outside the mounting groove. Then, pull the film flat on the roll, covering the mounting groove and the clamping plate. The head of the film is wrapped around the locking head. After ensuring that the film is flat and the edges are aligned, press the clamping plate to let the locking part enter the mounting groove. After the film has been wound on the roll for about half a turn, pull the film forcefully so that the end of the film applies external tension to the check bend. The check bend squeezes the gap between the side wall of the mounting groove and the locking part, thereby fixing the film. At this time, when the film is subjected to external force, the head of the film will not loosen, but will become tighter. The clamping plate is unable to rotate under the wrapping of the film, thus achieving reliable clamping of the film head. Attached Figure Description

[0009] In the diagram, 1 is the drum; 2 is the limiting end plate; 3 is the mounting groove; 4 is the clamping plate; 41 is the pressing part; 42 is the locking part; 43 is the check bend; and 44 is the elastic element. Detailed Implementation

[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0011] like Figure 1 and Figure 2 The shown take-up roller includes a drum 1 and two limiting end plates 2 located at both ends of the drum 1. The drum 1 has a mounting groove 3 parallel to its axis. A retaining plate 4 is rotatably connected within the mounting groove 3. The retaining plate 4 is rotatably connected to the two limiting end plates 2 via a pin. The retaining plate 4 includes a pressing part 41 on one side of the pin and a locking part 42 on the other side. The sidewall of the mounting groove 3 is adapted to the locking part 42. The end of the locking part 42 has a check bend 43, and the check bend 43 is connected to the locking part 42 via an elastic element 44. The retaining plate 4 is made of rubber, and the check bend 43, locking part 42, pressing part 41, and elastic element 44 are integrally formed.

[0012] When fixing the head of the film to be rolled, first flip the clamping plate 4 so that the locking part 42 is outside the mounting groove 3. Then, pull the film flat on the roll 1, covering the mounting groove 3 and the clamping plate 4. The head of the film is wrapped around the locking head. After ensuring that the film is flat and the edges are aligned, press the clamping plate 4 so that the locking part 42 enters the mounting groove 3. When the film has been wound on the roll 1 for about half a turn, pull the film forcefully so that the end of the film applies an external pulling force to the check bend 43. The check bend 43 squeezes the gap between the side wall of the mounting groove 3 and the locking part 42, thereby fixing the film. At this time, when the film is subjected to external force, the head of the film will not loosen, but will become tighter. The position of the clamping plate 4 is unable to rotate under the wrapping of the film, thus achieving reliable clamping of the film head.

[0013] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
