Description
Technical Field
[0001] The invention relates to the technical field of PVC pipe production equipment, in particular to a stirring and cooling device for PVC pipe production. Background Art
[0002] PVC is a material whose main component is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a synthetic material that is popular and widely used in the world today. During the production and processing of PVC pipes, the prepared materials must first be placed in the mixing equipment for mixing, and the temperature is raised to 120 degrees under high-speed mixing. However, the temperature of the materials cannot be controlled during this process. Since the rotation rate of the mixing end of the mixing equipment is consistent, the temperature of the materials will become higher and higher, and cooling equipment needs to be set up to cool the materials. However, the cooling effect of traditional cooling equipment cannot be automatically adjusted, and cannot be well coordinated with the change of material temperature, which makes it difficult for the mixed materials to stabilize in the temperature range of about 120 degrees. There is a lack of a device that can reduce the mixing rate of the mixing equipment in real time as the mixing time increases, and automatically adjust the cooling efficiency of the cooling equipment as the temperature of the material changes. The combination of the two helps to stabilize the temperature of the mixed materials in the optimal temperature range. Summary of the invention

[0011] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, after the material of the PVC pipe enters the stirring chamber, it is necessary to stir the material. First, the first motor is controlled to work, and the first transmission shaft is driven to rotate under the transmission of the first pulley and the first transmission belt, and then the first gear and the second gear meshing therewith are driven to rotate, and then the first rate switching gear located at the bottom meshing with the second gear is driven to rotate. At this time, since the diameters of the second gear and the first rate switching gear are close, the rotation speed of the first rotating shaft is controlled to be close to the rotation speed of the output end of the first motor. At this time, the rotation speed of the stirring blade driven by the first rotating shaft is the fastest gear, so as to achieve the effect of quickly raising the temperature of the material in the initial stirring state. After stirring for a period of time, it is necessary to gradually slow down the rotation speed of the stirring blade to avoid the temperature of the material being stirred being too high. At this time, with the rotation of the first transmission shaft, the transmission gear is driven. Every time the transmission gear rotates one circle, the first toothed disk is driven to rotate a certain angle. When the stirring blade rotates a certain number of circles and drives the transmission gear to rotate a certain number of circles, the teeth on the outer side of the first toothed disk mesh with and disengage from the drive gear, thereby driving the drive screw to rotate a certain number of circles. The first gear is then moved to the left of the gear, and the second gear is then moved to the right of the gear, and the second gear is then moved to the right of the gear.
[0012] In the present invention, before stirring the material, a certain amount of coolant is first filled into the cooling chamber, and then the second motor is controlled to work, driving the second transmission shaft to rotate, and then driving the fifth gear and the sixth gear meshing therewith to rotate, and then driving the second rate switching gear located at the bottom to rotate. With the rotation of the second rate switching gear, the cam rod is driven to rotate synchronously, and then the circulating gear is driven to rotate along the inner side of the second toothed plate, and then the piston rod is driven to reciprocate inside the circulating piston cylinder with the cooperation of the circulating connecting rod, and then part of the coolant at one end of the cooling chamber is pumped into the circulating piston cylinder through the pumping pipe, and the pumped coolant is discharged into the other end of the cooling chamber through the discharge pipe, and the above operation is continuously repeated, thereby realizing the circulation of the coolant inside the cooling chamber, and then taking away the heat inside the stirring chamber, and realizing the cooling effect on the material inside the stirring chamber; At this time, since the diameter of the second rate switching gear is much larger than the diameter of the sixth gear, the circulation speed of the coolant is relatively low in the initial stage of material mixing. As the mixing operation continues, the temperature inside the mixing chamber rises, and the driving end of the air pressure valve rises accordingly, driving the second lifting block connected to it to rise to a certain height inside the second lifting sleeve, thereby driving the second coaxial gear to rise to a certain height, mesh with and disengage from the tooth group at the bottom of the side end of the second driving rod, thereby driving the third bevel gear and the fourth bevel gear to rotate, thereby driving the fourth mounting rod to rise to a certain height while deflecting in the direction away from the third mounting rod, thereby driving the sixth gear to disengage from the second rate switching gear at the bottom. At the same time, it rises and meshes with the second rate switching gear on the top. At this time, the diameter of the meshed second rate switching gear is smaller than the diameter of the sixth gear compared with the previous second rate switching gear, thereby accelerating the rotation rate of the second rate switching gear while keeping the rotation rate of the sixth gear unchanged, thereby accelerating the rotation speed of the cam rod, thereby accelerating the circulation speed of the coolant in the cooling chamber, and so on. As the temperature inside the stirring chamber continues to rise, the circulation speed of the coolant in the cooling chamber will be increased accordingly, thereby better cooling the stirring material according to its temperature, achieving better cooling effect and helping to stabilize the temperature of the stirred material in the optimal temperature range.
[0013] In the present invention, when the first rotating shaft 21 rotates, the third gear 271 is driven to rotate, and then the fourth gear 272 meshing therewith is driven to rotate. Under the transmission of the second pulley 273 and the second transmission belt 274, the second rotating shaft 22 is driven to rotate synchronously, and the rotation directions of the first rotating shaft 21 and the second rotating shaft 22 are opposite, thereby driving the stirring blades 23 on the first rotating shaft 21 and the second rotating shaft 22 to rotate synchronously and in opposite directions, thereby performing a more comprehensive, sufficient and uniform stirring operation on the material inside the stirring chamber 12.
[0014] In the present invention, as the circulation of the coolant inside the cooling chamber 14 continues, since the temperature of the coolant drawn from the cooling chamber 14 to the inside of the circulating piston cylinder 441 is relatively high, the coolant inside the circulating piston cylinder 441 is intermittently injected into the inside of the circulating piston cylinder 441 to cool down the coolant, thereby further improving the cooling effect on the PVC pipe material.
