Description

Technical Field

[0001] The invention relates to the technical field of PVC pipe production, in particular to a material storage box for PVC pipe production. Background Art

[0002] With the continuous development of science and technology and the continuous improvement of people's living standards, the application scope of PVC pipes has become more and more extensive. PVC pipes are a kind of pipe products with strong toughness, good heat resistance and good ductility. It consists of three parts: upper layer, middle layer and lower layer. The upper layer of PVC pipe is a layer of paint film, which plays a role of waterproof and anti-aging; the middle layer is the polyvinyl chloride layer, which is the most important base layer; and the lower layer is the back-coated adhesive, which can be used for drainage, wastewater, chemicals, heating liquid and cooling liquid transportation, food, ultra-pure liquid, mud, gas, compressed air and vacuum system transmission.

[0003] At present, the common storage boxes for PVC pipe production on the market are usually manually unloaded by humans when unloading PVC pipe raw materials, which is not only time-consuming and labor-intensive, but also the unloading amount is uncertain. When unloading, since the PVC raw materials are accumulated inside the storage box for a long time, it is very easy to cause moisture inside the discharge box due to external influences, making the PVC raw materials inside the discharge box form lumps, which will cause the unloading port to be blocked during unloading, resulting in some materials being unable to be unloaded normally due to blockage, thereby reducing production efficiency. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a storage box for PVC pipe production, which allows workers to control the inclination angles of discharge plates on both sides according to the amount of material to be discharged, thereby achieving quantitative discharge. At the same time, through the barrier rods that are arranged, when the PVC raw materials fall through the discharge box, some agglomerated PVC raw materials come into contact with the barrier rods due to their own gravity when falling, and are crushed and dispersed by the barrier rods, thereby preventing some agglomerated PVC raw materials from clogging the discharge port, thereby improving the production efficiency and solving the problem that when the PVC pipe raw materials are discharged, they are usually discharged manually, which is not only time-consuming and labor-intensive, but also the amount of material discharged is uncertain. When discharging, since the PVC raw materials are accumulated in the storage box for a long time, it is very easy to cause moisture in the discharge box due to external influences, so that the PVC raw materials in the discharge box are agglomerated, which will cause the discharge port to be blocked during discharge, resulting in some materials being unable to be discharged normally due to blockage, thereby reducing production efficiency.

When the through groove of the second partition plate 19 coincides with the through groove on the surface of the first partition plate 18, the PVC raw material falls into the discharge box 201. When the material is discharged through the discharge box 201, some agglomerated PVC raw materials come into contact with the blocking rod 209 due to their own gravity when falling, and are crushed and dispersed by the blocking rod 209, thereby being discharged through the discharge plate 203.

[0055] Working principle: the staff connects the device to a power source, and then starts the sealing motor 307. The sealing motor 307 drives the driving rod 302 to rotate. The driving rod 302 drives the feeding gear 303 to rotate when rotating. The feeding gear 303 is meshed and connected with the connecting tooth plate 305 when rotating, so that the connecting tooth plate 305 drives the sealing plate 304 to move to one side, thereby opening the feeding box 301. Then the staff can transport the raw materials through the feeding box 301 to the inside of the storage barrel 1 for storage. Then the staff controls the sealing motor 307 to reverse, so that the sealing plate 304 can seal the feeding box 301. Then the staff starts the driving motor 9. The driving motor 9 drives the connecting gear 11 to rotate and mesh with the matching gear 10, driving the matching gear The wheel 10 rotates synchronously, and the gear 10 drives the rotating drum 6 to rotate synchronously when rotating. When the rotating drum 6 rotates, the stirring rod 7 can stir and turn the PVC raw materials inside the storage barrel 1, so as to prevent the PVC raw materials from agglomerating. At the same time, the temperature inside the storage barrel 1 can be detected by the temperature sensor.

When unloading is required, the staff connects the lower surface of the unloading box 201 to the After the transmission pipe, the pushing cylinder 212 is started, and the output end of the pushing cylinder 212 is retracted, driving the connecting frame 213 to slide inside the unloading box 201. At the same time, the sliding teeth 214 on both sides of the connecting frame 213 are meshed with the rotating gear 211 when moving, driving the rotating gear 211 to rotate, driving the rotating shaft 202 to rotate synchronously, and the rotating shaft 202 drives one side of the unloading plate 203 to rotate synchronously when rotating, so that the unloading plates 203 on both sides rotate relatively. When the unloading plates 203 rotate, the sliding rods 205 on the front and rear sides slide and limit in the sliding grooves 204, thereby opening the unloading box 201. The staff can control the inclination angle of the unloading plates 203 on both sides according to the amount of unloading required. At the same time, when the unloading plates 203 are tilted, the blocking rods 209 are matched with the rods 208 rotates between the inner walls of the matching block 207, and the matching block 207 rotates between the inner walls of the connecting groove through the connecting block and the connecting rod 206, so that the blocking rod 209 is in a horizontal state. At the same time, the staff starts the electromagnet 4, and the electromagnet 4 is magnetically adsorbed and fixed to the lower end of the rotating cylinder 6, so that when the rotating cylinder 6 rotates, it drives the electromagnet 4 to rotate synchronously, so that the electromagnet 4 drives the discharge plate 5 to rotate. When the groove of the discharge plate 5 coincides with the discharge groove on the surface of the blocking plate 215, the PVC raw material falls into the discharge box 201. When the material is discharged through the discharge box 201, some agglomerated PVC raw materials come into contact with the blocking rod 209 due to their own gravity when falling, and are crushed and dispersed by the blocking rod 209, so as to be discharged through the discharge plate 203. At the same time, when the rotating cylinder 6 rotates,The elastic cylinder 14 is driven to rotate by the stirring rod 7, and the elastic cylinder 14 drives the scraper 17 to rotate inside the storage barrel 1 through the support rod 15. The scraper 17 is continuously squeezed by the support rod 15, and the connection spring 16 pushes the support rod 15 back due to the elastic potential energy, so that the scraper 17 fits the inner wall of the storage barrel 1, so that the scraper 17 scrapes off the PVC raw material attached to the inner wall of the storage barrel 1.

The partition rod 209 crushes and scatters the PVC raw materials, preventing some agglomerated PVC raw materials from clogging the discharge port, thereby improving production efficiency. The drive motor 9 is provided to drive the connecting gear 11 to rotate and mesh with the matching gear 10, driving the matching gear 10 to rotate synchronously. The matching gear 10 drives the rotating drum 6 to rotate synchronously when rotating. When the rotating drum 6 rotates, the stirring rod 7 can stir and turn the PVC raw materials inside the storage barrel 1, thereby preventing the PVC raw materials from agglomerating, and at the same time facilitating the discharge efficiency of the PVC raw materials. The fan is provided to transport air to the stirring rod 7 through the connecting pipe 13 and the rotating drum 6, and exhaust air through the air outlet holes on the surface of the stirring rod 7, so that the air inside the storage barrel 1 is in a circulating state, thereby preventing the PVC raw materials inside the storage barrel 1 from agglomerating due to the moisture inside the storage barrel 1.
