Description

Technical Field

[0001] The utility model relates to the technical field of plasticizer production, in particular to a plasticizer discharging mechanism. Background Technique

[0002] Plasticizers are widely used as high molecular material additives in industrial production. The use of plasticizers can improve the performance of high molecular materials, reduce production costs, and improve production efficiency. They are an important type of chemical product additive and are commonly used as additives in materials such as plastic products, concrete, mortar, cement, gypsum, cosmetics, and cleaning agents. Especially in polyvinyl chloride plastic products, in order to increase the plasticity of plastics and improve the strength of plastics, phthalate esters need to be added, and their content can sometimes reach 50% of the product. The main function of plasticizers is to weaken the secondary bonds between resin molecules, increase the mobility of resin molecules, reduce the crystallinity of resin molecules, increase the plasticity of resin molecules, enhance their flexibility, and make them easy to process. They can be legally used for industrial purposes and are widely present in food packaging, cosmetics, medical devices, and environmental water bodies. For example, food wraps, food packaging, toys, etc.

[0003] The traditional discharging method of plasticizer reaction tanks is generally to discharge through valves, and it is easy for plasticizers to cause valve blockage. There is also a method of pouring out the plasticizer in the reaction tank by flipping the reaction tank. However, when the reaction tank is in a suspended state, the amplitude generated by the reaction tank during the reaction will be relatively large, which is prone to danger.

[0004] In order to improve the safety during the discharging of plasticizers, a patent document with the application number CN202321833069.3 and the name "A PVC Plasticizer Discharging and Flipping Mechanism" discloses a discharging flipping mechanism with high safety during the discharging process. When in use, start the motor, the output end of the motor drives the pulley to rotate, the belt drives two pulleys to rotate, and the two pulleys drive the screw rod to rotate, so that the screw rod can drive the lifting plate to move for lifting operations. Start the winch, the drum of the winch starts to rotate, and the towing rope is wrapped around the surface of the drum of the winch. The connecting block and the lower part of the plasticizer production tank can be pulled through the towing rope so that the plasticizer production tank can be flipped to pour out the PVC plasticizer in the plasticizer production tank. The screw rod can increase the height of the lifting plate and thus increase the height of the plasticizer production tank. When the plasticizer production tank does not need to be flipped for discharging, the height can be reduced so that the bottom of the plasticizer production tank fits the inner bottom wall of the installation chassis, preventing the plasticizer production tank from being in a suspended state and affecting the stability of the plasticizer production tank during operation. However, before flipping the production tank, it is necessary to move the lifting plate upward and then flip the production tank, and the operation is cumbersome when pouring out the plasticizer in the production tank.

[0005] In the patent document with the application number CN201621431509.2 and the title "PVC Plasticizer Discharging and Tilting Mechanism", a discharging and tilting mechanism is disclosed, which can improve the stability during tilting and avoid the intermittent discharging caused by the shaking of the PVC plasticizer inside the heating cylinder. It includes a fixed bracket and a heating cylinder, and the heating cylinder is horizontally arranged. One end of the heating cylinder is hinged to the fixed bracket through a hinge seat. A gear is connected to the other end of the heating cylinder. A translation block slidably connected to the fixed bracket is provided on the fixed bracket. An inclined surface inclined downward is provided at the top of the translation block, and teeth are provided on the inclined surface. The gear meshes with the teeth, and the translation block is connected to a driving structure capable of driving it to move in the horizontal direction. During operation, the translation driver drives the translation block to move leftward, and through the meshing of the gear and the teeth, the other end of the heating cylinder is turned upward, that is, discharging is realized. This discharging and tilting mechanism can improve the stability during tilting and avoid the intermittent discharging caused by the shaking of the PVC plasticizer inside the heating cylinder. However, it is not convenient to separate the heating cylinder from the fixed bracket and not convenient to remove the residual plasticizer in the heating cylinder. Utility Model Content

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0044] Embodiment 1: Refer to Figures 1 - 4 As shown, the plasticizer discharging mechanism includes a bottom plate 1, a bracket 2 is fixed on the right side of the bottom plate 1, and an arc-shaped rod 3 is fixed on the bottom plate 1. The arc-shaped rod 3 is fixedly connected to the bottom plate 1 and the bracket 2.

[0045] An arc-shaped groove 4 is formed in the arc-shaped rod 3, and an arc-shaped plate 5 is slidably clamped in the arc-shaped groove 4. The arc-shaped plate 5 is concentric with the arc-shaped rod 3. The arc-shaped plate 5 can slide in the arc-shaped groove 4 of the arc-shaped rod 3.

[0046] The upper end of the arc-shaped plate 5 is fixed with a cylinder body 6, and the upper end of the cylinder body 6 is open. Two support plates 7 are fixed on the support 2, and the two support plates 7 are symmetrically arranged front and back. The cylinder body 6 is located between the two support plates 7. A U-shaped groove 8 is formed on the support plate 7. Rotating shafts 9 are fixed on both the front and rear sides of the cylinder body 6. The two rotating shafts 9 are concentrically arranged. The rotating shaft 9 is rotatably arranged at the bottom of the groove 8, and the rotating shaft 9 is concentric with the arc-shaped rod 3. By providing the U-shaped groove 8, after the cylinder body 6 is located between the two support plates 7, the rotating shaft 9 can enter the groove 8. At the same time, it is convenient to take out the cylinder body 6 from between the two support plates 7.

[0047] A driving assembly for driving the rotating shaft 9 and the cylinder body 6 to rotate is arranged on the support plate 7. The driving assembly includes a toothed ring 10 concentrically fixed on the rotating shaft 9. An upper telescopic rod 13 is fixed on the support plate 7. A rack 12 is fixed on the telescopic end of the upper telescopic rod 13. The rack 12 meshes with the toothed ring 10. The length direction of the rack 12 is parallel to the axial direction of the upper telescopic rod 13, and the rack 12 is located above the toothed ring 10.

[0048] Refer to Figure 2 As shown, start the upper telescopic rod 13, so that the upper telescopic rod 13 drives the rack 12 to move in the left direction. During the process of the rack 12 moving in the left direction, the rack 12 can drive the cylinder body 6 to rotate through the toothed ring 10 and the rotating shaft 9. At this time, the rack 12 is located above the toothed ring 10. During the process of the rack 12 driving the rotating shaft 9 and the cylinder body 6 to rotate through the toothed ring 10, the rack 12 can limit the rotating shaft 9 at the bottom of the groove 8, and can improve the stability of the cylinder body 6 during the rotation process.

[0049] The upper telescopic rod 13 is fixed on the support plate 7 on one side of the groove 8, and a baffle 11 is fixed on the support plate 7 on the other side of the groove 8. The upper end of the rack 12 is in sliding contact with the lower end of the baffle 11. In order to further improve the stability of the rack 12 during the movement process, when the rack 12 moves below the baffle 11, the upper end of the rack 12 is in sliding contact with the lower end of the baffle 11. At this time, the baffle 11 can further stabilize the rack 12. During the process of the rack 12 driving the toothed ring 10, the rotating shaft 9 and the cylinder body 6 to rotate, it can make the rack 12 tightly mesh with the toothed ring 10, prevent the rack 12 from skipping teeth with the toothed ring 10 due to the large resistance during the movement process, and can improve the stability of the cylinder body 6 during the rotation process.

[0050] When it is necessary to remove the cylinder body 6, make the rack 12 move in the right direction. When the rack 12 is separated from the toothed ring 10, the rotating shaft 9 can be pulled out of the groove 8, and then the cylinder body 6 can be removed from between the two support plates 7. It is convenient to clean the cylinder body 6.

[0051] Embodiment 2: On the basis of Embodiment 1, refer to Figures 1 - 5 As shown, universal wheels 18 are installed at the four corners of the lower end of the bottom plate 1. By providing the universal wheels 18, it is convenient to move this discharging mechanism.

[0052] A brake assembly is provided on the arc-shaped plate 5. The brake assembly includes a chute 16 formed at the lower end of the arc-shaped plate 5. A pressing plate 17 is slidably disposed in the chute 16, and the lower end of the pressing plate 17 is in tight contact with the arc-shaped rod 3. A fixing plate 14 is fixed on the arc-shaped plate 5, and a lower telescopic rod 15 is fixed on the fixing plate 14. The telescopic end of the lower telescopic rod 15 is fixedly connected to the pressing plate 17.

[0053] Before moving this discharging mechanism, start the lower telescopic rod 15 to make the pressing plate 17 move downward and tightly abut against the arc-shaped rod 3. Use the frictional force between the pressing plate 17 and the arc-shaped rod 3 to stabilize the arc-shaped plate 5 and the cylinder body 6, and prevent the cylinder body 6 from rotating around the rotating shaft 9. When the whole discharging mechanism is moved, it can prevent the cylinder body 6 from shaking under the inertial action of the plasticizer in the cylinder body 6. It can further stabilize the cylinder body 6. When the whole discharging mechanism is moved, since the brake assembly can stabilize the cylinder body 6, it can avoid the frequent impact force generated by the gear ring 10 on the upper telescopic rod 13 through the rack 12 due to the shaking of the cylinder body 6, and can improve the service life of the upper telescopic rod 13.

[0054] During braking, in order to increase the frictional force between the pressing plate 17 and the arc-shaped rod 3, a brake shoe is fixed on the end face of the pressing plate 17 facing the arc-shaped rod 3. The pressing plate 17 makes the brake shoe tightly abut against the arc-shaped rod 3, which can increase the frictional force between the pressing plate 17 and the arc-shaped rod 3 and ensure the stability of the cylinder body 6 after braking.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
