During the conveying process, the width of the PVDF sheet can be controlled by the material blocking device, and the height of the lifting roller can be controlled by the lifting device, thereby controlling the thickness of the PVDF sheet after shaping; 2. In the present application, by setting the fixed plate, extrusion tube, feed valve, discharge port and piston, the material can be fed into the extrusion tube through the feed valve, and then the material is extruded onto the material conveying body through the discharge port provided by the extrusion tube, so that the material is initially formed on the material conveying body. At the same time, by adjusting the position of the piston, the number of discharge ports can be adjusted to facilitate the molding of PVDF boards of different widths; 3. In the present application, by setting the upper clamping block, groove, through groove, installation groove, lower clamping block, clamping slot, push plate, clamping plate, connecting plate, slide plate, slide bar, spring, connecting rod, middle plate, positioning block, plug rod and slot, the position of the piston in the extrusion tube can be adjusted by the plug rod, and then the push plate is pushed, and the push plate drives the positioning block to enter the clamping slot opened by the lower clamping block through the connecting rod and the middle plate. At this time, the connecting rod, the middle plate and the positioning block are all inserted into the clamping slot opened by the lower clamping block, and then the push plate is released. The spring pushes the push plate to move upward through the slide plate and the connecting plate, thereby driving the positioning block to be stuck in the clamping slot opened by the lower clamping block, and at the same time, the clamping plate set at the bottom of the push plate is inserted into the slot opened by the plug rod to realize the positioning of the plug rod.

At the same time, when the upper clamping block moves upward, the upper clamping block can be prevented from falling off under the action of the slider. When the lower clamping block is installed, the plugging block provided by the lower clamping block is inserted into the extrusion tube to position the lower clamping block. When the material is extruded, it is prevented that the material drives the piston and the plugging rod to drive the upper and lower clamping blocks to move left and right, so that the piston limit is more stable. 5.

At the same time, the heat conducting plate introduces the heat in the material into the heat conducting fins, and the heat conducting fins send the heat to the heat conducting pipe.

During the stirring process, the electric heating plate generates heat and transfers the heat to the heat-conducting rod to prevent the material from solidifying on the surface of the heat-conducting rod. At the same time, the card frame can install the vibration body at any position on the support rod through the rubber strip and fixed column provided by the rubber frame. At this time, the card frame and the vibration body are limited by the elasticity of the rubber frame and the rubber strip themselves. At the same time, the fixed column can make the shape of the rubber strip more complete and not easy to deform, making the installation more stable. When the vibration body vibrates, the rubber frame is used for buffering to reduce the transmission of vibration, making the installation of the vibration body more stable.

At this time, the card frame 921 and the vibration body 93 are limited by the elasticity of the rubber frame 922 and the rubber strip 923 themselves. At the same time, the fixed column 924 can make the shape of the rubber strip 923 more complete and not easy to deform, making the installation more stable. When the vibration body 93 vibrates, the rubber frame 922 is used for buffering to reduce the transmission of vibration, making the installation of the vibration body 93 more stable.
[0023] Working process: When the PVDF sheet production and forming device is used, firstly, the power is turned on, and then the feeding pipe of the feeding device is fixedly connected to the feeding valve 73, and then the material conveying body 3 and the active roller 4 are started by the control body 11, and then the feeding device delivers the material into the extrusion tube 72 through the feeding pipe and the feeding valve 73, and then the material enters the discharge port 74 through the extrusion tube 72 under the sealing effect of the piston 782 on both ends of the extrusion tube 72, and the material is delivered to the material conveying body 3 through the discharge port 74, and then the material conveying body 3 drives the extruded material to move, and at this time, the surface of the viscous material gradually forms a uniform plane, and at this time, the vibration body 93 and the electric heating plate 95 are started by the control body 11, and the electric heating plate 95 is energized to generate heat and deliver the heat to the heat conduction The vibrating body 93 drives the electric heating plate 95 and the heat-conducting rod 96 to vibrate through the vibrating plate 94. When the material flows near the heat-conducting rod 96, the vibrating heat-conducting rod 96 drives the material to vibrate, so that the material is fully mixed, the bubbles are discharged, and the quality of the PVDF sheet is improved. When the material gradually moves away from the heat-conducting rod 96, the surface of the material tends to be flat again. Through the continuous flow of the material, the two sides of the material gradually solidify. At the same time, the solidified materials on both sides contact with the fixed shell 82. The material conveying body 3 drives the material to move. At this time, the circulating water pump 85 is started by the control body 11. The circulating water pump 85 drives the coolant to circulate in the heat-conducting pipe 84. Then the material contacts the heat-conducting plate 83, and a large amount of heat in the material is lost, so that the two sides of the material are gradually shaped. Then the material The material is fed into between the active roller 4 and the lifting roller 5 under the action of the material conveying body 3. At this time, the active roller 4 rotates to squeeze the material into a PVDF sheet of suitable thickness while conveying the material. When it is necessary to produce PVDF sheets of different widths, the push plate 771 is first pressed down, and the push plate 771 drives the card plate 772, the connecting plate 773 and the connecting rod 777 to move downward. At this time, the card plate 772 slides downward in the slot 783 opened by the insertion rod 781, and the connecting plate 773 pushes the slide plate 774 to move downward on the outside of the slide rod 775, so that the spring 776 is compressed, and the connecting rod 777 drives the positioning block 779 to move downward through the middle plate 778. When the bottom of the push plate 771 contacts the inner wall of the bottom of the groove 752 opened by the upper card block 751, the card plate 772 slides downward in the slot 783 opened by the insertion rod 781. The connecting plate 773 pushes the slide plate 774 to move downward on the outside of the slide rod 775, so that the spring 776 is compressed. The connecting rod 777 drives the positioning block 779 to move downward through the middle plate 778. When the locking cam 751 is in the unlocking state, the locking cam 752 is in the unlocking state, and the locking cam 753 is locked.The upper clamping block 751 drives the push plate 771, the connecting rod 777, the middle plate 778 and the positioning block 779 to move upward on the outer side of the plug plate 762 and the slider 763, and at the same time, the push plate 771 drives the plug plate 762 to move upward. After the clamping plate 772 leaves the slot 783 opened by the plug rod 781, the plug rod 781 can be moved. At this time, the plug rod 781 can push the piston 782 in the extrusion tube 72 to move. By moving the piston 782 to a suitable position, some of the discharge ports 74 cannot be connected to the feed valve 73 through the extrusion tube 72, thereby increasing or By reducing the number of discharge ports 74 and then changing the discharge amount, the discharge range can be controlled, thereby controlling the width of the PVDF sheet during molding. After the discharge port 74 is adjusted, the push plate 771 is pushed downward, and the upper clamping block 751 is driven downward by the push plate 771. At this time, the push plate 771 drives the clamping plate 772 to enter the slot 783 opened by the insertion rod 781. At the same time, the push plate 771 drives the connecting rod 777, the middle plate 778 and the positioning block 779 to move in the clamping slot 764 opened by the lower clamping block 761. When the upper clamping block 751 is in the groove 752 opened by the upper clamping block 751 and the bottom of the upper clamping block 751 is in contact with the lower clamping block 761, the upper clamping block 751 is pushed toward the side close to the fixed plate 71, and the upper clamping block 751 drives the connecting rod 777, the middle plate 778 and the positioning block 779 to enter the groove 764 opened by the lower clamping block 761 through the pushing plate 771, and then the pushing plate 771 is released, and the spring 776 pushes the pushing plate 771 to move upward through the sliding plate 774 and the connecting plate 773, and the pushing plate 771 drives the positioning block 779 through the connecting rod 777 and the middle plate 778. 79 moves upward to realize the positioning of the upper block 751 and the lower block 761. At the same time, the card plate 772 is inserted into the slot 783 opened by the plug rod 781. When the material is extruded, the plug rod 781 can be limited to prevent the piston 782 from being pushed out of the predetermined position. At this time, the hydraulic telescopic rod 81 can be controlled to extend and shorten by the control body 11. The position of the fixed shell 82 is adjusted by the hydraulic telescopic rod 81 to ensure the width of the PVDF sheet. At the same time, the lifting roller 5 is driven up and down by the lifting body to adjust the thickness of the produced PVDF sheet.
