Abstract

The utility model relates to a continuous unwinding machine, which relates to unreeling conveying operation. The utility model is especially suitable for a bag-making machine, and is composed of a supporting frame, a bracket, a core shaft, three guide rollers, a pressure roller, a cam, a handle, and a tension spring. When a roll is replaced, the cam is rotated to lead the pressure roller to be tightly pressed with a guide roller on one end. Tension of subsequent paper is kept. Procedures normally proceed. A paper tail on a work position can be released and can be bound with a paper head on another work position. Then, a machine set can not stop because of the replacement of rolls and can always keep continuous operation.

Description

A kind of continuous unreeling machine

The utility model relates to and unreels the conveying operation, is specially adapted to bag machinery.

Patent Office of the People's Republic of China discloses the patent that the patent No. is 87215557 and is called " refinforced cement packaging bag of glass zero twisted yarn and Fabricating machinery thereof ", assigned this patent and produce unit of Foochow package packing machine factory, this unit paper-feeding mechanism has two unreeling machines, and each is made up of three deflector rolls putting the tensioning paper effect that plays on mandrel, the support on two support rollers, the support roller each unreeling machine by two on support, the support.Two unreeling machines respectively unreel for the outer paper of packaging bag and internal layer paper; often occur a unreeling machine in the practical operation and put paper; another unreeling machine has not but been put paper; need whole compressor emergency shutdown this moment; change the paper roll of having put; because paper roll lifting; joint is bonding; man-hours such as correction; delay time; and this moment not the preceding volume end paper of the paper of change of lap and positive change of lap entered the glass zero twisted yarn that following operation just sticked glue and twined; it is of a specified duration to stall for time; overlong time on the glue adhere papers can make paper strength influenced, and therefore this unreeling machine is not only wasted man-hour but also influenced product design.

The purpose of this utility model is to overcome the defective of above-mentioned unreeling machine, and a kind of unreeling machine of energy continuous working is provided.

The utility model scheme is such: two stations are set on single unreeling machine support, every station is all formed by one group of support roller is secondary, respectively place a mandrel on the support roller, kink a cam and handle respectively on terminal deflector roll two head end axles, cam and handle relative fixed, there is a hold-down roller terminal deflector roll top, cam heads on two head end axles of hold-down roller, there is one of an extension spring to hang on this axle head, the other end hangs on the cam face, and compresses roller end axle kink in the vertical direction elongated slot of support.

When being change of lap, advantage of the present utility model do not shut down, and the tension force requirement can keep the last paper change of lap of volume the time, save man-hour, guarantee product design.

Accompanying drawing is continuous unreeling machine structural representation.

1 is left support roller pair among the figure, and 2 is left mandrel, and 3 for paper roll transmits paper, and 4 is right support roller pair, and 5 is hold-down roller, and 6 for compressing the roller end axle, and 7 is cam, and 8 are extension spring, and 9 is handle, and 10 is terminal deflector roll end axle, and 11 is the terminal deflector roll, and 12 is the top deflector roll, and 13 are the transition deflector roll.

The utility model is to implement like this: unit has four of two unreeling machines to unreel station, two secondary support rollers are arranged on each unreeling machine support, every secondary support roller has two pairs of support rollers to place the mandrel two ends, two left and right sides mandrels respectively are placed on the two secondary left and right sides support roller pairs and become parallel shape, also are provided with three deflector rolls on the support: top deflector roll, transition deflector roll, terminal deflector roll.Kink a cam and a handle on terminal deflector roll two head end axles, cam and handle relative fixed, there is a hold-down roller terminal deflector roll top, cam heads on two head end axles of hold-down roller, there is one of an extension spring to hang on this axle head, the other end hangs on the cam face, and compress roller end axle kink in the vertical direction elongated slot of support, compressing the roller end axle can move up and down in the elongated slot of support two, when cam major diameter end was gone up the hold-down roller top, extension spring was loosened, and hold-down roller separates with the terminal deflector roll, when cam after angle orientation of rotation under the handle effect, hold-down roller is by conducting oneself with dignity and tension spring tension is pressing the terminal deflector roll.

During unit operation; before the paper roll on one of them station of unreeling machine has been put soon; be placed on the support roller of two after the mandrel of another station on the support is inserted in new paper roll; then; turning handle; put down hold-down roller, deflector roll normally carries out following operation to the paper tension that leads between the mechanism to make paper clamp keep eventually between hold-down roller and terminal deflector roll.Then the paper roll that will be about to put is totally released, with the first adhesion of the paper of paper end and another paper roll, because the effect of hold-down roller has kept the preceding paper of terminal deflector roll not influence the normal operation continuously of unit in the relaxed state adhesion.The paper bonding along with the front paper sheet delivery enters tensioning state by relaxed state, just drives the new paper roll of second volume and enters continuous working.

Claims

1, a kind of continuous unreeling machine, form by support, support roller, deflector roll, it is characterized in that being provided with on the support two stations, every station is all formed by one group of support roller is secondary, respectively place a mandrel on the support roller, kink a cam and handle respectively on terminal deflector roll two head end axles, cam and handle relative fixed, there is a hold-down roller terminal deflector roll top, cam heads on two head end axles of hold-down roller, have one of an extension spring to hang on this axle head, the other end hangs on the cam face, and compresses roller end axle kink in the vertical direction elongated slot of support.
