Embodiment 1

[0051] figure 1 , figure 2 The shown a kind of film rewinding and rewinding device comprises two turntables 1 that can rotate before and after, two rewinding shafts are installed in parallel between the front and rear two turntables 1, i.e. rewinding reel 11 and rewinding reel 12, rewinding reel 11 and rewinding reel 12. The rewinding shafts 12 are symmetrical about the rotation axis of the turntable 1. When rewinding, one of the rewinding shafts is located at the winding position and is called the main reeling shaft 11, and the other reeling shaft is located at the unloading position and is called the backup reeling shaft 12. Reel 11 is positioned at the right side of turntable rotating shaft, and standby winding shaft 12 is positioned at the left side of rotating disk 1 rotating shaft, and two winding shafts are turned over under the drive of rotating disk 1 and take turns as main winding shaft and spare winding shaft; Root film guide rollers 13; one of the film guide roll...

Embodiment 2

[0058] A film rewinding and changing method is characterized in that the film rewinding and changing device of Embodiment 1 is used, and the steps include the following steps in turn:

[0059] (1), the main winding shaft 11 performs normal winding; the spare winding shaft 12 is covered with a paper core tube 8;

[0060] In the normal winding process, the main winding shaft performs normal winding to form a film roll 81, the sliding support 2 is located at the rightmost end of its moving track, the touch roller 21 is separated from the film roll 81, the first cylinder 31 is in a contracted state, and the second The second cylinder 41 is in contracted state, and the small cylinder 61 is in contracted state; the movable roller bracket 73 is positioned at the lowest point of its vertical moving track; The film storage mechanism 7 passes through the gap space between the fixed roller row and the movable roller row (that is, the section of the film 80 passing between the fixed rolle...

Abstract

The invention discloses a film winding and replacing device. According to the film winding and replacing device, a sliding support is further installed on the right side of a main winding shaft in a transverse moving mode, a touch roller is further mounted at the left end of the sliding support, a main swing arm mechanism and a secondary swing arm mechanism are further arranged on the sliding support, the main swing arm mechanism comprises a front main swing arm, a rear main swing arm, a front first air cylinder and a rear first air cylinder, the secondary swing arm mechanism comprises a front secondary swing arm, a rear secondary swing arm, a front second air cylinder and a rear second air cylinder, a cutter mechanism and an auxiliary pressing roller extending longitudinally are installed between the left ends of the two main swing arms, the cutter mechanism comprises a cutter and a rodless air cylinder, the cutter is driven by the rodless air cylinder to move in the longitudinal direction, and a rolling roller extending longitudinally is movably installed between the left ends of the front secondary swing arm and the rear secondary swing arm. The invention further provides a film winding and replacing method. When a film is cut off, the cutting line of the film is parallel to the central axis of the main winding shaft, waste is avoided, and automatic bottoming is achieved.

Description

technical field [0001] The invention belongs to the technical field of film production equipment, and in particular relates to a film rewinding and changing device and a rewinding and changing method. Background technique [0002] Ordinary films can be rolled onto paper core tubes to form rolls after being formed. When the coiled film roll reaches the set diameter, the roll needs to be changed. [0003] When changing the roll, the cutter moves along the width of the film to cut off the film, and then the front edge of the film (the film part between the tangent line and the new winding shaft is called "film front") is smoothly laid on the paper of the new winding shaft. On the surface of the core barrel, this process is commonly known as "priming". [0004] In order to realize that there is no need to stop the machine when changing rolls, flip-type film winding and roll changing equipment is generally used. Flip-type film rewinding and changing equipment includes two rota...
