The invention aims to provide a thermoplastic film traction device, which solves the problem that the traditional thermoplastic film traction device cannot realize continuous traction of a thermoplastic film.
In order to solve the problems, the technical scheme of the invention is as follows: the thermoplastic film traction device comprises a traction track and a transmission belt, wherein the traction track is positioned below the transmission belt and is parallel to the conveying direction of the transmission belt, and the transmission belt is connected with a motor for driving the transmission belt to run; the traction device further comprises a fixer for fixing the thermoplastic film on the traction track, the fixer comprises a positive pressure plate and side pressure plates connected to two ends of the positive pressure plate, rubber pads for bonding the thermoplastic film are paved on one surface, in contact with the traction track, of the two side pressure plates, and the positive pressure plate is connected to the conveying belt.
The working principle of the scheme is as follows:
when the thermoplastic film traction device is used, firstly, a thermoplastic film is placed on a traction track, one of the retainers is used for fixing the thermoplastic film on the traction track, the positive pressure plate of the retainer presses the thermoplastic film, the side pressure plates of the retainer are contacted with two sides of the track, the rubber pads on the side pressure plates press the side edges of the thermoplastic film to be attached to the track, a motor is started, a transmission belt starts to run, and the transmission belt drives the retainer to move together due to the fact that the positive pressure plate of the retainer is connected with the transmission belt, and then drives the thermoplastic film to move, and the thermoplastic film slides on the traction track to realize forward traction; when the other turning position of the conveying belt is reached, the side pressing plate of the fixer rotates upwards, but the thermoplastic film moves towards the rolling direction, and the side pressing plate of the fixer is separated from the thermoplastic film due to inconsistent moving direction, at the moment, the fixer at the other turning position of the conveying belt then fixes the thermoplastic film and drives the thermoplastic film to move forwards for traction, so that continuous traction on the thermoplastic film is realized.
The beneficial effect of this scheme:
the two turning positions of the transmission belt are respectively provided with a fixer for fixing the thermoplastic film, the lower part of the transmission belt is provided with a traction track in parallel, when the thermoplastic film is drawn, the thermoplastic film is fixed on the traction track by the fixer, when the transmission belt rotates, the fixer can draw the thermoplastic film to move forwards, and when the first fixer moves to the next turning position, the second fixer moves to the turning position again, the thermoplastic film is continuously fixed on the track, and the rotation of the transmission belt is realized so that the thermoplastic film is continuously drawn.
Further, an anti-sticking layer for preventing the thermoplastic film from sticking is arranged on the traction track. An anti-sticking layer is arranged on the traction track to prevent the thermoplastic film from adhering to the traction channel and prevent the thermoplastic film from moving on the traction track.
Further, the positive pressure plate is detachably connected with the transmission belt. The positive pressure plate and the transmission belt are detachably connected, and when the fixing device is damaged, the fixing device can be directly detached for maintenance through the threaded connection.
Further, an anti-slip layer is arranged on the positive pressure plate. An anti-slip layer is arranged on the positive pressure plate, so that friction force between the positive pressure plate and the thermoplastic film is increased, relative sliding between the thermoplastic film and the positive pressure plate is prevented, the thermoplastic film is separated from the positive pressure plate, and transmission of the thermoplastic film is affected.
Further, the traction track is formed by connecting two tracks. Because the width of the thermoplastic film is very wide, a very wide traction track is needed, and the traction track is arranged to be connected with two tracks, so that the material can be saved.

fig. 2 is a schematic view of the traction rail of fig. 1.
Detailed Description
The invention is described in further detail below by way of specific embodiments:
reference numerals in the drawings of the specification include: a conveyor belt 1, a holder 2, a rubber pad 3, a thermoplastic film 4, a traction rail 5, a positive pressure plate 201, a side pressure plate 202.
An example is substantially as shown in figures 1 and 2: the thermoplastic film traction device comprises a traction track 5 and a transmission belt 1, wherein an anti-adhesion layer for preventing the thermoplastic film 4 from adhering is arranged on the traction track 5, the anti-adhesion layer is high-temperature non-adhesion paint GN-205, the traction track 5 is positioned below the transmission belt 1 and parallel to the conveying direction of the transmission belt 1, and the transmission belt 1 is connected with a motor for driving the transmission belt to operate; the traction device further comprises two fixing devices 2 used for fixing the thermoplastic films 4 on the traction track 5, the number of the fixing devices 2 is two, each fixing device 2 comprises a positive pressure plate 201 and side pressure plates 202 connected to two ends of the positive pressure plate 201, rubber pads 3 used for bonding the thermoplastic films 4 are paved on one surfaces of the two side pressure plates 202, which are in contact with the traction track 5, of the two side pressure plates, the positive pressure plate 201 is in threaded connection with the transmission belt 1, an anti-slip layer is arranged on the positive pressure plate 201, and the anti-slip layer is a BD75 anti-slip layer.
In the thermoplastic film traction device, a fixer 2 for fixing a thermoplastic film 4 is arranged on a transmission belt 1, traction tracks 5 are arranged in parallel at the lower part of the transmission belt 1, when the thermoplastic film 4 is traction, the thermoplastic film 4 is firstly placed on the traction tracks 5, the fixer 2 fixes the thermoplastic film 4 on the traction tracks 5, a positive pressure plate 201 of the fixer 2 presses the thermoplastic film 4, side pressure plates 202 of the fixer 2 are contacted with two sides of the tracks, rubber pads 3 on the side pressure plates 202 press the side edges of the thermoplastic film 4 to be attached to the tracks, a motor is turned on, the transmission belt 1 starts to run, and the positive pressure plate 201 of the fixer 2 is connected with the transmission belt 1, so that the transmission belt 1 drives the fixer 2 to move together, and then drives the thermoplastic film 4 to slide on the traction tracks 5, so that forward traction is realized; when the other turning position of the transmission belt 1 is reached, the side pressure plate 202 of the holder 2 rotates the transmission belt 1 upward, but the thermoplastic film 4 moves in the winding direction, the side pressure plate 202 of the holder 2 separates from the thermoplastic film 4 due to the inconsistent movement direction, and when the first holder 2 moves to the next turning position, the second holder 2 moves to the turning position again, continues to fix the thermoplastic film 4 on the track, and then drives the thermoplastic film 4 to move forward and pull, so that the rotation of the transmission belt 1 is realized to continuously carry out the pulling of the thermoplastic film 4.
