Description

Technical Field

[0001] The present application relates to the technical field of cast film machines, and in particular to a universal cast film machine. Background Art

[0002] Cast film machine is a kind of equipment specially used for producing plastic film. In the process of cast film, plastic particles or particles and other additives are heated and melted, extruded and formed, stretched and cooled by a set of rollers, and finally formed into a continuous flat film, so that plastic films with different properties and uses can be produced, which are widely used in food packaging, medical supplies, building materials and other fields.

[0003] An ASA cast film machine mentioned in an existing Chinese public patent (authorization announcement number: CN219686333U) can quickly conduct heat from the film slurry by embedding a heat conduction plate on the forming frame. The heat conduction plate contacts the film slurry discharged from the discharge platform. A heat dissipation component is arranged under the heat conduction plate. Through the cooperation of a serpentine coil, a heat-absorbing copper bar, a heat dissipation rack, a cold water tank, a water pipe and a water pump, the heat-absorbing copper bar absorbs the heat of the heat conduction plate, and the serpentine coil and the heat dissipation fan inside the heat dissipation rack quickly dissipate the heat of the heat-absorbing copper bar, thereby improving the heat dissipation effect and efficiency of the film slurry as a whole.

[0004] When using the existing cast film machine, the cooled film needs to be wound up. After the winding is completed, the staff can remove the winding roller. However, since it takes a long time to complete the winding, the staff may do other work during this time. It is possible that the staff may not notice the completion of the winding roller in the first place, thereby interrupting the operation of the cast film machine and reducing the processing efficiency.

[0037] When in use, firstly, polymer and solvent are conveyed to the mixer in a certain proportion, and the mixer stirs them evenly to form a uniform solution, then the raw materials enter the feed pipe 3, and then the raw materials are conveyed into the mold 5 through the feed pipe 3, and the raw materials can be processed into a film through the mold 5. At this time, the film is pulled out of the mold 5 by the action of the traction roller 7, and conveyed to the cooling roller 25, so that the film contacts the cooling roller 25. During the contact process, the cooling roller 25 quickly conducts the heat of the film to solidify it. After the solidification is completed, the film is conveyed to the winding roller 8, and the film is wound up by the winding roller 8 for subsequent use, and the edge material is processed by the edge material hand-rolling roller 9 to ensure the uniformity of the film, thereby completing the work of the cast film machine, which can be used to study polymer materials and manufacture cast films with specific properties and functions, and achieves the purpose of small size, small footprint, and is suitable for use in laboratories or small production sites. The warning mechanism can timely alarm to remind the staff to replace the winding roller 8, thereby reducing the downtime of the cast film machine, and the film can be evenly cooled by the cooling mechanism.

[0038] Reference Figure 3 and Figure 4 The warning mechanism includes a fixed block 10 fixedly connected to the top of a mounting plate 6 on one side, a horizontal plate 11 is fixedly connected to one side of the fixed block 10, a lifting block 14 is arranged below the horizontal plate 11, a roller 15 is rotatably connected inside the lifting block 14, the roller 15 contacts the winding roller 8, a connecting block 16 is fixedly connected to one side of the lifting block 14, and a contact block 17 is fixedly connected to the top of the connecting block 16.

[0039] Among them, a movable plate 18 is slidably provided on one side of the fixed block 10, and a sensing block 19 is fixedly connected to the bottom of the movable plate 18.

[0041] When the winding roller 8 is winding the film, the roller 15 will contact the surface of the film. When the winding roller 8 is continuously winding, the film on the winding roller 8 gradually becomes thicker. At this time, the roller 15 is forced to drive the lifting block 14 to move upward, and the lifting block 14 moving upward will drive the connecting block 16 upward, and the connecting block 16 drives the contact block 17 to rise. After the winding roller 8 completely winds up the film, the contact block 17 will contact the induction block 19. The induction block 19 is a sensing probe and is electrically connected to the control panel 4. Through the preset program, the control The panel 4 controls the buzzer 20 to start, thereby reminding the staff to replace the winding roller 8. After the film is completely wound up by the winding roller 8, the warning system is automatically triggered, so that the winding roller 8 can be replaced in time to reduce the shutdown of the production line, effectively reduce the time of production interruption, and improve the production efficiency and the stability of the production line. When the lifting block 14 moves upward, the lifting block 14 will squeeze the telescopic rod 12 and the spring 13. The spring 13 generates elastic potential energy after compression. The reaction force of the elastic potential energy makes the roller 15 always contact with the film.

[0042] Reference Figure 3 and Figure 4 A fixed frame 21 is fixedly connected to one side of the fixed block 10, and a threaded rod 22 is rotatably connected to the inner bottom wall of the fixed block 10. The top of the threaded rod 22 passes through the movable plate 18 and the fixed frame 21 and is fixedly connected to a handle 23. The threaded rod 22 is threadedly connected to the movable plate 18, and the threaded rod 22 is rotatably connected to the fixed frame 21.

The guide column 24 is slidably connected to the movable plate 18 . Both ends of the guide column 24 are fixedly connected to the inside of the fixed frame 21 .

[0044] When winding different films, the threaded rod 22 is driven to rotate by rotating the handle 23, and the movable plate 18 is threadedly connected to the threaded rod 22, so that the movable plate 18 moves inside the fixed frame 21, and the movement of the movable plate 18 drives the sensor block 19 to move, so that the distance between the resistance block 17 and the sensor block 19 can be adjusted. By adjusting the distance between the resistance block 17 and the sensor block 19, it can be flexibly adjusted according to the characteristics of the film and the winding conditions, thereby improving the applicability and flexibility of the production process.

[0046] When cooling the film, first connect the water inlet pipe to one end of the cooling roller 25, and connect the other end of the cooling roller 25 to the water outlet pipe. After the connection is completed, the coolant is sent into the refrigeration chamber 26. The water level of the coolant rises inside the refrigeration chamber 26. When the water level reaches the position of the water outlet pipe, the delivery of the coolant is stopped. At this time, the coolant will flow between the cooling roller 25 and the refrigeration chamber 26 under the action of gravity, and flow between two adjacent guide plates 28. The guide plates 28 are set in a threaded shape. The cooling roller 25 is rotated so that the coolant is continuously brought up to cool the film. By rotating the cooling roller 25, the coolant can be evenly distributed on the inner wall of the cooling roller 25, thereby achieving uniform cooling of the film, which helps to reduce quality problems caused by excessively high or low local temperatures of the film.

[0047] refer to Figure 1 and Figure 2 , located above the edge material hand-increasing roller 9, a wire arrangement device 29 is arranged between the mounting plates 6 on both sides, the wire arrangement device 29 is adapted to the edge material hand-increasing roller 9, guide rails 30 are fixedly connected to the top two sides of the frame 1, and sliders are slidably connected to the two sides of the guide rails 30, and the sliders are fixedly connected to the mounting plates 6.

The combined use can improve the winding speed and accuracy. When maintenance is required, the mounting plate 6 can be moved away from the frame 1 through the guide rail 30, so as to facilitate maintenance by the staff.

[0049] Working principle: the raw material is fed into the feed pipe 3, and then fed into the mold 5 through the feed pipe 3. The raw material can be processed into a film through the mold 5. At this time, the film is pulled out of the mold 5 by the traction roller 7 and transmitted to the cooling roller 25, so that the film contacts the cooling roller 25. During the contact process, the cooling roller 25 quickly conducts the heat of the film to solidify it. After the solidification is completed, the film is transported to the winding roller 8, and the film is wound by the winding roller 8, while the edge material is processed by the edge material hand-rolling roller 9. After the winding roller 8 completely winds up the film, the resistance block 17 will resist the induction block 19. The induction block 19 is a sensing probe and is electrically connected to the control panel 4. Through the preset program, the control panel 4 controls the buzzer 20 to start, thereby reminding the staff to replace the winding roller 8, thereby reducing the downtime of the cast film machine.
