Technical Field

The utility model relates to a film guide roller, more specifically the film guide roller buffer structure that says so relates to.

Background

In the operation process of the film laminating machine, the moving direction of the film is mainly guided by a plurality of film guide rollers, and in the process of advancing the film, the length of the film can be changed due to the temperature change on the film, so that in order to ensure the conveying efficiency of the film, a film guide roller buffer structure is additionally arranged on the film laminating machine, the length of the film is adjusted, and the tension of the film is kept.

The utility model discloses a film guide roller buffer structure among the prior art mainly is through setting up the mode of a film guide roller that can move about from top to bottom and realizes the regulation to the film rate of tension, this film guide roller realizes the elevating action to the film guide roller through setting up cylinder drive's mode at its both ends to this rate of tension of adjusting the film, however because the cylinder at film guide roller both ends is independent operation, consequently asynchronous problem can appear very easily, so just can lead to the film guide roller to be in the tilt state, lead to the in-process of film guide to appear a series of problems.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a film guide roller buffer structure that film guide roller can not incline.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a film guide roller buffer structure, includes the film guide roller and connects the left cylinder and the right cylinder at film guide roller both ends respectively, still includes two synchronizing part, two synchronizing part sets up on the both ends of film guide roller, the gangbar is worn to be equipped with coaxially in the film guide roller, the both ends and the synchronizing part linkage of gangbar to make the synchronous oscilaltion in both ends of film guide roller.

As a further improvement of the utility model, the synchronizing part comprises a rack fixed on the external frame by the laminating and a gear coaxially sleeved at the two ends of the linkage rod, and the gear is meshed with the rack.

As a further improvement, the two ends of the film guide roller are respectively provided with a slider, the sliders are respectively fixed on the push rods of the left air cylinder and the right air cylinder, and the side surfaces of the sliders are respectively fixed with a cushion pad.

As the utility model discloses a further improvement, the side of going up the side guide film roller dorsad of the slider that is fixed in guide film roller left end is fixed with the response piece, the side is fixed with the stainless steel reflector panel on the response piece, is equipped with photo sensor directly over this stainless steel reflector panel, photo sensor is fixed in the outside frame to when the guide film roller rises to the highest position, sense the stainless steel reflector panel.

The beneficial effects of the utility model, through the setting of left cylinder and right cylinder, the effect of the synchronous oscilaltion in both ends about alright effectual realization drive guide film roller, and the cooperation through synchronizing part and gangbar, the synchronization that can step forward in both ends that realize guide film roller, so compare in prior art only adopt left cylinder and the synchronous mode of right cylinder make about guide film roller can be better go on in step to go up and down, so avoid appearing guide film roller slope and lead to a series of problems that the guide film in-process appears.

fig. 2 is a cross-sectional view of the film guide roller of fig. 1.

Detailed Description

The present invention will be described in further detail with reference to embodiments shown in the drawings.

Referring to fig. 1 to 2, the film guide roller buffer structure of the present embodiment includes a film guide roller 1, a left cylinder 2 and a right cylinder 3 respectively connected to two ends of the film guide roller 1, and two synchronizing members 4, where the two synchronizing members 4 are disposed at two ends of the film guide roller 1, a linkage rod 5 coaxially penetrates through the film guide roller 1, two ends of the linkage rod 5 are linked with the synchronizing members 4 to enable two ends of the film guide roller 1 to be lifted up and down synchronously, in a process of using the film guide roller buffer structure of the present embodiment, only the whole structure needs to be connected between two processes to enable a film to bypass the film guide roller 1, then in a process of advancing the film, the film guide roller 1 is driven to rotate, and when a problem of loosening the film occurs, the film guide roller 1 is driven to move up and down by the action of the left cylinder 2 and the right cylinder 3, so as to achieve an effect of tensioning the film, and because the setting of synchronizing part 4 and gangbar 5, alright realize carrying out the synchronization action to the displacement at film guide roller 1 both ends at the in-process of moving from top to bottom of film guide roller 1, compare like this and only adopt about the cylinder to carry out the mode of synchronizing in prior art, great increase the synchronism at both ends about film guide roller 1, so effectual avoided among the prior art because the problem that the slope appears in film guide roller 1 that the cylinder stroke difference leads to about.

As an improved specific embodiment, the synchronizing part 4 includes a rack 41 attached to and fixed on the external frame and a gear 42 coaxially sleeved at two ends of the linkage rod 5, the gear 42 is engaged with the rack 41, and the rotation of the linkage rod 5 can be simply and effectively used to synchronize two ends of the film guide roller 1, wherein the film guide roller 1 of the embodiment is coaxially sleeved on the linkage rod 5 and is connected with the linkage rod 5 through a bearing, so that the two ends can rotate independently.

As an improved specific embodiment, the two ends of the film guide roller 1 are respectively provided with a sliding block 11, the sliding blocks 11 are respectively fixed on the push rods of the left cylinder 2 and the right cylinder 3, the upper side surfaces of the sliding blocks are respectively fixed with a cushion pad 12, and the arrangement of the cushion pads 12 can realize the buffer effect in the process of pushing the left cylinder 2 and the right cylinder 3, so as to avoid the problem of damage caused by impact.

As an improved specific embodiment, a sensing sheet 111 is fixed on one side of the upper side surface of the slider 11 fixed at the left end of the film guide roller 1, which is opposite to the film guide roller 1, a stainless steel reflecting plate 112 is fixed on the upper side surface of the sensing sheet, a light sensor 113 is arranged right above the stainless steel reflecting plate 112, and the light sensor 113 is fixed on an external frame, so that when the film guide roller 1 rises to the highest position, the stainless steel reflecting plate 112 is sensed, thus the position of the film guide roller 1 can be fed back to an external PLC, the closed-loop control of the film guide roller 1 is realized, and the control accuracy of the film guide roller 1 is greatly increased.

In conclusion, the buffer structure of the embodiment can simply and effectively realize the effect of linking the two ends of the film guide roller 1 by the combination of the synchronizing component 4 and the linkage rod 5, and the problem that the film guide roller 1 is inclined is avoided.
