Description

Technical Field

[0001] This utility model relates to the field of polyester film production technology, and in particular to a polyester film winding device. Background Technology

[0002] After the polyester film is produced, it is wound onto a paper tube by a winding device. Some existing winding devices have a tube-changing function. After the polyester film on the paper tube reaches a certain thickness, glue is sprayed onto the new paper tube. After the polyester film is cut, the end of the polyester film is attached to the glue on the new paper tube, and the new paper tube starts to rotate to start a new round of winding. During the use of the above-mentioned winding devices, the new paper tube often rotates before the glue has formed strength, causing the polyester film to fall off the paper tube, which in turn leads to the interruption of the winding work and affects the production of polyester film. Utility Model Content

[0003] In order to solve the problem that the polyester film in existing winding devices is prone to falling off the paper tube, this utility model proposes a polyester film winding device to prevent the polyester film from falling off the paper tube.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A polyester film winding device includes a positioning roller group, a support roller, a glue coating mechanism, and a winding and cutting mechanism. The support roller is located in front of the positioning roller group, which conveys the polyester film backward. The support roller supports the lower side of the polyester film. The winding and cutting mechanism includes a sliding seat, an air shaft, a winding machine, a film cutting mechanism, a lifting mechanism, and a following mechanism. The air shaft is horizontally rotatably connected to the sliding seat and driven by the winding machine. A paper tube is mounted on the air shaft. The film cutting mechanism is located in front of the air shaft and mounted on the sliding seat for cutting the polyester film. The lifting mechanism drives the sliding seat to move up and down, and the following mechanism drives the sliding seat to move back and forth. There are two winding and cutting mechanisms, named a working mechanism and a standby mechanism. The air shaft of the working mechanism is located in front of the support roller and winds the polyester film through the paper tube. The air shaft of the standby mechanism is located above the positioning roller group and the support roller. The glue coating mechanism is located above the paper tube of the air shaft of the standby mechanism.

[0005] Furthermore, the film cutting mechanism includes a support plate, an electric push rod, a bracket, and a heating wire. The support plate is fixedly connected to the sliding seat, the bracket is installed on the lower side of the support plate via the electric push rod, and the heating wire is installed on the lower side of the bracket.

[0006] Furthermore, the following mechanism of the working mechanism is located on the left side of the polyester film, and the following mechanism of the standby mechanism is located on the right side of the polyester film. The following mechanism includes a guide rail, a first motor and a first screw. The guide rail extends in the front and back direction and can move up and down under the drive of the lifting mechanism. The sliding seat is slidably connected to the guide rail, and the first screw is rotatably connected to the guide rail and driven by the first motor. The first screw is threadedly connected to the sliding seat.

[0007] Furthermore, the lifting mechanism of the working mechanism is located on the left side of the polyester film, and the lifting mechanism of the standby mechanism is located on the right side of the polyester film. The lifting mechanism includes a second screw, a second motor and a base. The second screw is vertically rotatably connected to the upper side of the base and driven by the second motor.

[0020] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] like Figures 1 to 9 This utility model proposes a polyester film winding device. Figure 1 The front, back, left, right, up, and down directions of the winding device are defined to describe the technical solution. The winding device includes a positioning roller group 3, a support roller 4, a glue coating mechanism 5, and a winding and cutting mechanism. The positioning roller group 3 includes two vertically arranged power rollers that extend horizontally. The support roller 4 is located in front of the positioning roller group 3, extends horizontally, and can rotate freely. The produced polyester film 200 passes between the two power rollers. Driven by the power rollers, the positioning roller group 3 conveys the polyester film backward, and the support roller 4 supports the polyester film. On the underside of the film, the polyester film lies horizontally between the positioning roller group 3 and the support roller 4. A winding and cutting mechanism is used to wind and cut the polyester film. This mechanism includes a sliding seat 6, an air shaft 7, a winding machine 8, a film cutting mechanism 9, a lifting mechanism 10, and a following mechanism 11. The air shaft 7 extends laterally, and its end is horizontally rotatably connected to the sliding seat 6. It is driven by the winding machine 8, which can be a motor-driven structure. A paper tube 12 is mounted on the air shaft 7. The air shaft 7 is commercially available, and the paper tube 12 is fitted onto the air shaft 7. After compressed air is introduced into the air shaft 7, the paper tube 12 can be locked onto the air shaft 7. After depressurization, the paper tube 12 can be removed from the air shaft 7. The film cutting mechanism 9 is located on the front side of the air shaft 7 and is mounted on the sliding seat 6. It is used to cut the polyester film. The film cutting mechanism 9 can adopt a cutting blade structure, a laser structure, or other structures, which are not limited for the time being. The lifting mechanism 10 is used to drive the sliding seat 6 to move up and down. The lifting mechanism 10 can adopt a cylinder, a hydraulic cylinder, or other structures, which are not limited for the time being. The following mechanism 11 is used to drive the sliding seat 6 to move back and forth. The following mechanism 11 can adopt a linear module, a screw and nut structure, or other structures, which are not limited for the time being. There are two winding and cutting mechanisms, named the working mechanism and the standby mechanism respectively. The air shaft 7 of the working mechanism is located in front of the support roller 4 and winds up the polyester film through the paper tube 12. The air shaft 7 of the standby mechanism is located above the positioning roller group 3 and the support roller 4. The standby mechanism is located behind the working mechanism and the air shaft 7 of the standby mechanism is located above the polyester film. The glue coating mechanism 5 is located above the paper tube 12 of the air shaft 7 of the standby mechanism.

[0022] The working principle of the winding machine's 8-mechanism is as follows: Figure 4Initially, after the polyester film is produced, it passes through the positioning roller set 3 and the support roller 4 successively, and is wound onto the paper tube 12 on the working mechanism. On-site personnel visually inspect the thickness of the polyester film on the paper tube 12, or measure the length of the polyester film based on the number of rotations of the driving roller of the positioning roller set 3. When the amount of polyester film on the paper tube 12 meets the requirement, the gluing mechanism 5 applies glue to the upper side of the paper tube 12 on the air expansion shaft 7 of the standby mechanism. The air expansion shaft 7 of the standby mechanism rotates 180 degrees to turn the glue to the lower side of the paper tube 12. At this time, the distance between the glue and the polyester film is h, where 1cm<h<10cm, so that the glue can quickly contact the polyester film in the subsequent process. The winder 8 of the standby mechanism can adopt a servo motor to accurately control the rotation angle of the air expansion shaft 7, for example Figure 5 , the following mechanism 11 of the standby mechanism drives the sliding seat 6 to move forward, and the movement speed of the sliding seat 6 is substantially consistent with the forward speed of the polyester film. Meanwhile, the lifting mechanism 10 of the standby mechanism drives the sliding seat 6 to move downward to approach the polyester film, for example Figure 6 When the lower side of the paper tube 12 moves to the height where the polyester film is located, the glue contacts the polyester film, and the lifting mechanism 10 stops moving downward. At this time, the sliding seat 6 of the standby mechanism continues to move forward at the same speed as the polyester film under the action of the corresponding following mechanism 11, so that the glue and the polyester film are in stable contact, allowing the glue to form strength during this period. When the standby mechanism approaches the support roller 4, for example Figure 7 the film cutting mechanism 9 of the standby mechanism cuts the polyester film, and then the working mechanism moves forward under the drive of the corresponding following mechanism 11 to give way to the standby mechanism, for example Figure 8 the standby mechanism moves past the support roller 4 to the original position of the working mechanism, and the standby mechanism takes over the original working mechanism to start winding the polyester film. After manually removing the paper tube 12 from the original working mechanism, a new paper tube 12 is reinstalled, and then the sliding seat 6 moves to the original position of the standby mechanism under the action of the lifting mechanism 10 and the following mechanism 11 to prepare for the next roll change, for example Figure 9 .

[0023] In one embodiment, for example Figure 2 the film cutting mechanism 9 comprises a support plate 91, an electric push rod 92, a bracket 93 and a heating wire 94. The support plate 91 extends in the left-right direction, and the end of the support plate 91 is locked on the sliding seat 6 by a fastener and moves along with the sliding seat 6. The bracket 93 is installed on the lower side of the support plate 91 through the electric push rod 92, and the electric push rod 92 is installed vertically for driving the bracket 93 to move up and down. The heating wire 94 is installed on the lower side of the bracket 93, and the bracket 93 tensions the heating wire 94 in the left-right direction. The heating wire 94 is at high temperature after being energized. The working principle of the film cutting mechanism 9 is as follows: the electric push rod 92 extends to drive the heating wire 94 to move downward, the heating wire 94 cuts off the polyester film by using high temperature, then the electric push rod 92 retracts to reset the heating wire 94.

[0024] In one embodiment, for example Figure 1 and Figure 2 The following mechanisms 11 of the working mechanism and the standby mechanism are respectively located on the left and right sides of the polyester film. The following mechanism 11 of the working mechanism is located on the left side of the polyester film, and the following mechanism 11 of the standby mechanism is located on the right side of the polyester film to prevent interference between the working mechanism and the standby mechanism during movement. The following mechanism 11 includes a guide rail 111, a first motor 112, and a first screw 113. The guide rail 111 extends forward and backward and can move up and down under the drive of the lifting mechanism 10. The air shaft 7 of the working mechanism is provided with a sliding seat 6 only on the left end. The sliding seat 6 of the working mechanism is slidably connected to the guide rail 111 on the left side of the polyester film. The air shaft 7 of the standby mechanism is provided with a sliding seat 6 only on the right end. The sliding seat 6 of the spare mechanism is slidably connected to the guide rail 111 on the right side of the polyester film. The first screw 113 is rotatably connected to the guide rail 111 and driven by the first motor 112. The first screw 113 is threadedly connected to the sliding seat 6. When the first motor 112 drives the first screw 113, the first screw 113 and the sliding seat 6 rotate relative to each other. The sliding seat 6 moves forward or backward along the guide rail 111. The first motor 112 can be a servo motor to improve the rotation accuracy of the first motor 112 and facilitate the control of the movement speed of the sliding seat 6. In addition, a grating ruler can be installed on the guide rail 111 to further improve the movement speed accuracy of the sliding seat 6.

[0025] In one embodiment, such as Figure 1 and Figure 2 The lifting mechanisms 10 of the working mechanism and the standby mechanism are respectively located on the left and right sides of the polyester film. The lifting mechanism 10 of the working mechanism is located on the left side of the polyester film, and the lifting mechanism 10 of the standby mechanism is located on the right side of the polyester film to prevent interference between the working mechanism and the standby mechanism during movement. The lifting mechanism 10 includes a second screw 101, a second motor 102, and a base 103. The second screw 101 is vertically rotatably connected to the upper side of the base 103 and is driven by the second motor 102. The second screw 101 is threadedly connected to the guide rail 111. The second motor 102 drives the second screw 101, and the second screw 101 rotates relative to the guide rail 111. The guide rail 111 moves up or down, thereby driving the sliding seat 6 on the guide rail 111 to move up and down accordingly. The second motor 102 can be a servo motor to improve the rotation accuracy of the second motor 102 and facilitate the control of the vertical movement distance of the guide rail 111. In addition, a grating ruler can be installed on the side of the second screw 101 to further improve the vertical movement distance accuracy of the guide rail 111.

[0026] In one embodiment, such as Figure 1 and Figure 2 A column 13 is fixedly connected to the upper side of the base 103, and a top plate 14 is fixedly connected to the upper end of the column 13. The upper end of the second screw 101 is rotatably connected to the top plate 14 to improve the stability of the second screw 101 and the guide rail 111.

[0027] In one embodiment, such as Figure 1 and Figure 2 The top plate 14 is fixedly connected to the connecting plate 15. The glue application mechanism 5 includes a glue pump (not shown in the figure) and a glue application head. The glue pump is connected to the glue application head through a hose. The glue pump can pump glue to the glue application head. The glue application head is fixedly connected to the lower side of the connecting plate 15. The glue application head extends to the left and right to facilitate the even spraying of glue onto the upper side of the paper tube 12 of the standby mechanism.
