Description

Deviation correction device for winding and unwinding machine

technical field

The utility model belongs to the technical field of coating, printing, film covering and the like with paper and film as the base material, and in particular relates to a deviation correcting device for a winding and unwinding machine.

Background technique

In the processing line with film and paper as the base material, in order to ensure the tidy rewinding and unwinding, the overall correction is usually equipped, otherwise, it needs to be rewound once outside the line before it can be used on the machine; It will also produce axial movement, and the spool with serious movement needs to be unloaded and rewound; these two situations often occur, which have a great impact on continuous production.

The existing process deviation correction technology is complex, and the overall deviation correction technology for winding and unwinding takes up a lot of space, requires a lot of power.

Utility model content

The purpose of this utility model is to overcome the deficiencies of the prior art and provide a rectifying device for unwinding and unwinding machines. Just install this deviation correcting device on the rack to solve the deviation problem of the film path.

In order to achieve the above object, the utility model adopts the following technical solutions:

The utility model provides a deviation correcting device for a rewinding and rewinding machine, which includes a power source, two sets of roll-shaped film fixing mechanisms and a translation mechanism symmetrically arranged, and the roll-shaped film fixing mechanism includes a cylinder, a cylinder base and a chuck. The base of the cylinder is arranged at the bottom of the cylinder, the piston rod of the cylinder is connected with the chuck, a mandrel is arranged between the two chucks, and the bases of the two cylinders are connected by connecting pieces; the translation mechanism includes a lead screw, a lead screw nut , slide rail and frame, the slide rail is set between the frame and the cylinder base, one end of the screw is connected to the output end of the power source, the other end of the screw is connected to the frame, and the screw nut is set on the screw , the upper surface of the lead screw nut is fixedly connected with the cylinder base near the power source side.

The connecting piece is composed of a concave member. The concave member is composed of a horizontal section and two vertical sections vertically arranged at both ends of the horizontal section. The heights of the two vertical sections are the same.

The power source includes a support frame and a power mechanism, and the output end of the power mechanism is connected with a lead screw.

The power mechanism is motor or manual.

Compared with the prior art, the utility model has the beneficial effects:

1. The utility model is simple in structure, small in size, light in weight, takes up little space, is very lightweight and flexible, and only needs tens of watts of power to drive it, and can realize deviation correction of two single rolls separately. It has a wide range of applications, is simple and practical .

2. After the installation of the structure of the utility model, the original spools do not need off-line rewinding and can be used directly on the machine, and the spools that move during the production process do not need to be rewound off the machine; during the production process, the online can be easily It is convenient to adjust the position of the film shaft, and the deviation correction effect is very good, which meets the needs of production.

Description of drawings

Fig. 1 is the structural representation of the utility model.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to Fig. 1, a rectifying device for a rewinding and unwinding machine includes a power source 1, two sets of roll-shaped film fixing mechanisms and a translation mechanism symmetrically arranged, and the roll-shaped film fixing mechanism includes a cylinder 2 and a cylinder base 3 And the chuck 4, the cylinder base 3 is arranged at the bottom of the cylinder 2, the piston rod of the cylinder 2 is connected with the chuck 4, the mandrel 10 is arranged between the two chucks 4, and the connecting piece 5 is passed between the two cylinder bases 3 Connected, the connecting piece 5 is a concave member, the concave member is composed of a horizontal section and two vertical sections vertically arranged at both ends of the horizontal section, the height of the two vertical sections is the same; the translation mechanism includes a lead screw 6 , lead screw nut 7, slide rail 8 and frame 9, slide rail 8 is arranged between frame 9 and cylinder base 3, one end of lead screw 6 is connected with the output end of power source 1, and the other end of lead screw 6 is connected with The frame 9 is connected, the leading screw nut 7 is sleeved on the leading screw 6, and the leading screw nut 7 is fixedly connected with the cylinder base near the power source side.

Working principle: When it is found that the coiled article on the mandrel 10 deviates, manually or electrically adjust the lead screw 6 to correct the deviation online to the normal position, avoiding the problem that the coiled coil needs to be rewound outside the line, and at the same time during the production process The shifting film spool no longer needs to be unloaded and rewound.
