Description

Technical Field

[0001] The invention relates to the technical field of PVC film cooling, in particular to a mold temperature controller for PVC film cooling and a use method thereof. Background Art

[0002] The mold temperature controller for PVC film cooling is a device used to control the temperature of the mold. It is mainly used to cool the mold during the production process of PVC film to ensure the quality and production efficiency of the PVC film. The mold temperature controller, also known as the mold temperature controller, was originally used in the temperature control industry of injection molds. With the development of the machinery industry, the application scope of the mold temperature controller has gradually expanded. Now, air cooling and water cooling are mainly used to cool the PVC film. Air cooling takes away the heat from the surface of the PVC film by forced air, and water cooling takes away the heat from the film by direct contact of the coolant with the surface of the PVC film.

[0003] When the PVC film is cooled by water cooling, the coolant is generally sprayed downward on the surface of the PVC film to remove the heat from the surface of the PVC film. However, spraying the coolant only on the top of the PVC film will result in the coolant being unable to contact the bottom of the PVC film, causing some heat to remain on the bottom of the PVC film, resulting in poor cooling effect of the PVC film.

[0019] Furthermore, a method for using a mold temperature controller for cooling a PVC film comprises the following steps:

[0020] S1: The PVC film enters the interior of the cooling rack through the feed hole and is discharged through the discharge rack. When the PVC film moves inside the cooling rack, the spraying component is activated to start working, and the coolant in the storage rack is sprayed onto the surface of the PVC film through the spraying component. The spraying component can spray the coolant on the upper and lower surfaces of the PVC film;

[0021] S2: The cylindrical tube drives the cross to rotate when it rotates, and the water pump starts to work. The water pump draws the coolant in the storage rack into the transmission pipe through the connecting pipe. The coolant is transmitted to the inside of the cylindrical tube through the hose and the installation pipe and sprayed on the surface of the PVC film through the nozzle to cool it.

[0022] S3: When the inclined plate moves upward, the lifting frame is pushed to slide on the surface of the slide plate through the connection between the linkage rod and the push plate. When the arc extrusion plate is separated from the cross, the lifting frame is reset by the elasticity of the spring, so that the through-hole frame can drive the PVC film to swing up and down inside the cooling rack;

[0023] S4: When the through-hole frame slides downward, the tension of the PVC film will decrease when the through-hole frame moves downward, causing the PVC film to slide down before the contact plate. When the through-hole frame moves downward, it will push the movable frame downward through the connection between the bent plate and the synchronization rod. When the movable frame moves downward, it will push the contact plate to contact the surface of the PVC film and cause the PVC film to vibrate.

[0024] The present invention has the following beneficial effects:

[0025] The PVC film of the present invention enters into the interior of the cooling rack through the feed hole and is transmitted out through the discharge rack. When the PVC film moves inside the cooling rack, the spraying component is started to start working, and the cooling liquid in the storage rack is sprayed onto the surface of the PVC film through the spraying component. The spraying component can spray the cooling liquid on the upper and lower surfaces of the PVC film, thereby improving the cooling efficiency of the PVC film. When the spraying component is working, it will push the separation component to move up and down. When the separation component moves up and down, it will pull the PVC film to shake inside the cooling rack, so that the cooling liquid on the surface of the PVC film can fall into the interior of the cooling rack and fall into the interior of the storage rack through the leakage hole for recycling, thereby avoiding the waste of the cooling liquid. When the separation component moves up and down, it will drive the positioning component to move up and down synchronously. The contact between the positioning component and the PVC film will generate vibration, and the vibration can cause the cooling liquid on the surface of the PVC film to fall off quickly.

[0026] The present invention starts a power device to drive the rotating rod to rotate. When the rotating rod rotates, the engagement of the driving wheel and the rotating wheel drives the cylindrical tube to rotate inside the groove plate. When the cylindrical tube rotates, the cross is driven to rotate. At the same time, the water pump is started to start working. The water pump will draw the coolant in the storage rack into the inside of the transmission pipe through the connecting pipe. The coolant will be transmitted to the inside of the cylindrical tube through the hose and the installation pipe and sprayed on the surface of the PVC film through the nozzle to cool it. The cross is located at the upper and lower ends of the PVC film, and can cool the upper and lower surfaces of the PVC film at the same time, thereby improving the cooling efficiency of the PVC film.

[0027] When the cross of the present invention rotates, it pushes the circular arc extrusion plate to contact the rubber roller rod and pushes the force-bearing plate to rotate downward. When the force-bearing plate rotates, it pushes the inclined plate to move upward through the center rod. When the inclined plate moves upward, it pushes the lifting frame to slide on the surface of the slide plate through the connection between the connecting rod and the push plate. When the circular arc extrusion plate is separated from the cross, the lifting frame will be reset by the elasticity of the spring, so that the through-hole frame can drive the PVC film to shake up and down inside the cooling frame, so that the coolant on the surface of the PVC film can quickly fall off to the inside of the cooling frame, and the coolant falling into the cooling frame will be transmitted to the inside of the storage frame through the leakage hole for recycling, thereby avoiding waste of coolant. A triangular scraper is arranged inside the through-hole frame, which can scrape off the coolant on the surface of the PVC film, thereby avoiding waste caused by the coolant falling off at the outer end of the cooling frame.

[0028] When the through-hole frame slides downward, the tension of the PVC film will decrease when the through-hole frame moves downward, causing the PVC film to slide off before the contact plate. When the through-hole frame moves downward, the connection between the bent plate and the synchronization rod will push the movable frame to move downward. When the movable frame moves downward, the contact plate will be pushed to contact the surface of the PVC film and cause the PVC film to vibrate. The vibration will cause the coolant on the surface of the PVC film to fall off quickly, thereby improving the treatment effect of the coolant.

[0029] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] There are two groove rings 35, and the ends of the mounting tube 33 and the hose 30 that are away from each other are respectively connected to the two groove rings 35. The ends of the mounting tube 33 and the hose 30 that are away from each other both penetrate the cooling rack 1 and extend to the interior of the cooling rack 1. The rotating wheel 31 is located at one end of the cylindrical tube 21 close to the cross 28.

[0050] The surface of the rotating wheel 31 meshes with the surface of the driving wheel 22, and the driving wheel 22 is located inside the semicircular frame 2. The power device 23 of the present invention starts to drive the rotating rod 24 to rotate. When the rotating rod 24 rotates, the cylindrical tube 21 rotates inside the groove plate 20 through the meshing of the driving wheel 22 and the rotating wheel 31. When the cylindrical tube 21 rotates, it drives the cross 28 to rotate, and at the same time, the water pump 27 is started to work. The water pump 27 will draw the coolant in the storage rack 13 into the inside of the transmission pipe 29 through the connecting pipe 25. The coolant will be transmitted to the inside of the cylindrical tube 21 through the hose 30 and the mounting pipe 33 and sprayed on the surface of the PVC film through the nozzle 32 to cool it.

In the present invention, when the through-hole frame 46 slides downward, the tension of the PVC film will decrease when the through-hole frame 46 moves downward, causing the PVC film to slide off before the contact plate 64. When the through-hole frame 46 moves downward, it will push the movable frame 62 to move downward through the connection between the bent plate 60 and the synchronization rod 61.

The contact plate 64 is located below the vertical rod 63.

[0056] A method for using a mold temperature controller for cooling a PVC film, comprising the following steps:

[0057] S1: The PVC film enters the interior of the cooling rack 1 through the feed hole 10 and is discharged through the discharge rack 4. When the PVC film moves inside the cooling rack 1, the spraying component 6 is activated to start working, and the cooling liquid in the storage rack 13 is sprayed onto the surface of the PVC film through the spraying component 6. The spraying component 6 can spray the cooling liquid on the upper and lower surfaces of the PVC film;

[0058] S2: The cylindrical tube 21 drives the cross 28 to rotate when rotating, and the water pump 27 is started to work. The water pump 27 will pump the coolant in the storage rack 13 into the inside of the transmission pipe 29 through the connecting pipe 25. The coolant will be transmitted to the inside of the cylindrical tube 21 through the hose 30 and the installation pipe 33 and sprayed on the surface of the PVC film through the nozzle 32 to cool it;

[0059] S3: When the inclined plate 44 moves upward, the lifting frame 43 is pushed to slide on the surface of the slide plate 47 through the connection between the linkage rod 48 and the push plate 52. When the arc extrusion plate 40 is separated from the cross 28, the lifting frame 43 is reset by the elasticity of the spring 45, so that the through-hole frame 46 can drive the PVC film to swing up and down inside the cooling rack 1;

[0060] S4: When the through-hole frame 46 slides downward, the tension of the PVC film will decrease when the through-hole frame 46 moves downward, causing the PVC film to slide down before the contact plate 64. When the through-hole frame 46 moves downward, it will push the movable frame 62 to move downward through the connection between the bent plate 60 and the synchronization rod 61. When the movable frame 62 moves downward, it will push the contact plate 64 to contact the surface of the PVC film and cause the PVC film to vibrate.

[0061] When in use, the PVC film enters the interior of the cooling rack 1 through the feed hole 10 and is transmitted through the discharge rack 4. When the PVC film moves inside the cooling rack 1, the spraying component 6 is started to start working, and the coolant in the storage rack 13 is sprayed onto the surface of the PVC film through the spraying component 6. The spraying component 6 can spray the coolant on the upper and lower surfaces of the PVC film to improve the cooling efficiency of the PVC film. When operating, the spraying component 6 will push the separation component 7 to move up and down. When moving up and down, the separation component 7 will pull the PVC film to shake inside the cooling rack 1, so that the coolant on the surface of the PVC film can fall into the interior of the cooling rack 1, and fall into the interior of the storage rack 13 through the leakage hole 11 for recycling, thereby avoiding waste of coolant. When the separation component 7 moves up and down, it will drive the positioning component 8 to move up and down synchronously. The positioning component 8 will vibrate when it contacts the PVC film. The vibration can make the coolant on the surface of the PVC film fall off quickly. The power device 23 is started to drive the rotating rod 24 to rotate. When the rotating rod 24 rotates, the cylindrical tube 21 is driven to rotate inside the groove plate 20 through the meshing of the driving wheel 22 and the rotating wheel 31. When the cylindrical tube 21 rotates, it drives the cross 28 to rotate. At the same time, the water pump 27 is started to work. The water pump 27 will pump the coolant in the storage rack 13 into the inside of the transmission pipe 29 through the connecting pipe 25. The coolant will be transmitted to the inside of the cylindrical tube 21 through the hose 30 and the installation pipe 33 and sprayed on the surface of the PVC film through the nozzle 32 to cool it. The cross 28 is located at the upper and lower ends of the PVC film and can cool the upper and lower surfaces of the PVC film at the same time, thereby improving the cooling efficiency of the PVC film. When the cross 28 rotates, it pushes the arc extrusion plate 40 to contact the rubber roller 41 and pushes the force plate 51 to rotate downward. When the force plate 51 rotates, it pushes the inclined plate 44 to move upward through the center rod 42. When the inclined plate 44 moves upward, it pushes the lifting frame 43 to slide on the surface of the slide plate 47 through the connection between the connecting rod 48 and the push plate 52. When the arc extrusion plate 40 is separated from the cross 28, the lifting frame 43 will be reset by the elasticity of the spring 45, so that the through-hole frame 46 can drive the PVC film to shake up and down inside the cooling frame 1, so that the coolant on the surface of the PVC film can quickly fall off to The coolant falling into the cooling rack 1 will be transmitted to the storage rack 13 through the leak hole 11 for recycling, so as to avoid the waste of coolant. A triangular scraper 53 is arranged inside the through-hole rack 46, and the triangular scraper 53 can scrape the coolant on the surface of the PVC film, so as to avoid the coolant falling off and wasting on the outer end of the cooling rack 1. When the through-hole rack 46 slides downward, the tension of the PVC film will decrease when the through-hole rack 46 moves downward, so that the PVC film will slide down before the contact plate 64. When the through-hole rack 46 moves downward, the connection between the bent plate 60 and the synchronous rod 61 will push the movable rack 62 to move downward. When the movable rack 62 moves downward, it will push the contact plate 64 to contact with the surface of the PVC film and cause the PVC film to vibrate.Vibration will cause the coolant on the surface of the PVC film to fall off quickly, improving the treatment effect of the coolant.
