[0034] In this embodiment, as Figure 1 and Figure 2As shown in the figure, a feeding device for PVC production includes a storage tank body 1, on which an adjustment component 2 is installed. The adjustment component 2 is used to increase the feeding height of the storage tank body 1. The adjustment component 2 includes a connecting plate 21, a bearing frame 22, a rack plate 23, a telescopic member 24 and a braking member 25. One end of the connecting plate 21 is fixedly connected to the storage tank body 1, and the other end of the connecting plate 21 passes through the sliding groove of the bearing frame 22 and is fixedly connected to the rack plate 23. The rack plate 23 is inserted into the top through groove of the bearing frame 22. The telescopic member 24 is installed at the bottom of the bearing frame 22, and the output end of the telescopic member 24 is fixedly connected to the bottom end of the rack plate 23. By driving the rack plate 23 to move upward along the top through groove of the bearing frame 22 through the output end of the telescopic member 24, the connecting plate 21 drives the storage tank body 1 to rise. The braking member 25 is used to lock the position of the rack plate 23 in the bearing frame 22.

[0035] Thus, when it is necessary to adjust the use height of the storage tank body 1, start the telescopic member 24. The output end of the telescopic member 24 drives the rack plate 23 to move upward along the top through groove of the bearing frame 22. At the same time, the rack plate 23 drives the storage tank body 1 to move upward through the connecting plate 21. When the adjustment of the use height of the storage tank body 1 is completed, use the braking member 25 to reinforce the position of the rack plate 23 to prevent the rack plate 23 from accidentally moving downward. By adjusting the use height of the storage tank body 1, it is convenient for the storage tank body 1 to add PVC raw materials into PVC production equipment at different heights.

[0036] Furthermore, the storage tank body 1 is used to store PVC raw materials. A sliding groove is processed on one side of the bearing frame 22. The connecting plate 21 connects the rack plate 23 and the storage tank body 1. The top through groove of the bearing frame 22 restricts the up and down movement of the rack plate 23. The telescopic member 24 provides power for the movement of the rack plate 23. The braking member 25 prevents the rack plate 23 from accidentally moving downward and increases the stability of the rack plate 23 after adjustment.

[0037] In some embodiments, as Figure 2 shown, the braking member 25 includes a mounting seat 251, a rotating shaft 252, a gear 253, two clamping sleeves 254 and a positioning pin 255. The mounting seat 251 is fixedly connected to the bearing frame 22. The gear 253 is rotatably connected to the mounting seat 251 through the rotating shaft 252. The gear 253 is meshed with the rack plate 23. The two clamping sleeves 254 are symmetrically installed at both ends of the rotating shaft 252. The clamping sleeve 254 is connected to the mounting seat 251 through the positioning pin 255. By inserting the positioning pin 255 into the groove of the clamping sleeve 254, the rotation of the gear 253 in the mounting seat 251 is restricted, and the position of the rack plate 23 in the bearing frame 22 is locked by the gear 253.

[0038] Further, the rotating shaft 252 rotates in the mounting seat 251 through bearings, and the gear 253 rotates together with the rotating shaft 252. A plurality of grooves are evenly distributed on the outer circumference of the ferrule 254. The outer wall of the positioning pin 255 is processed with threads. Since the gear 253 and the rack plate 23 are in a meshing state, the positioning pin 255 is used to prevent the rotating shaft 252 from rotating in the mounting seat 251, and thus the gear 253 brakes the rack plate 23.

[0039] In some embodiments, as Figure 3 shown, a disc 211 is fixedly connected to the connecting plate 21. A roller 212 is hinged in each of the two discs 211, and the outer circumference of the roller 212 is in contact with the carrier 22.

[0040] Further, two discs 211 are provided on the outer wall of the connecting plate 21, and two rollers 212 are provided in each disc 211. When the connecting plate 21 moves in the carrier 22, the design of the rollers 212 reduces the friction between the connecting plate 21 and the carrier 22 and improves the smoothness of the connecting plate 21 when it rises.

[0041] In some embodiments, as Figure 1 and Figure 5 shown, a moving assembly 3 is fixedly connected to the bottom end of the carrier 22. The moving assembly 3 is used to drive the storage tank body 1 to move and feed materials to equipment at different positions. The moving assembly 3 includes a bracket 31, a universal wheel 32, and a support member 33. The top end of the bracket 31 is fixedly connected to the carrier 22. The universal wheel 32 is installed at the bottom of the bracket 31. The universal wheel 32 drives the storage tank body 1 to move to different positions, and the support member 33 prevents the storage tank body 1 from tipping over.

[0042] Further, four universal wheels 32 are provided at the bottom of the bracket 31. The design of the universal wheels 32 facilitates the movement of the bracket 31 to drive the overall mechanism. The support member 33 is designed on one side close to the storage tank body 1 to prevent the storage tank body 1 from tilting to one side under the action of gravity when it is filled with raw materials.

[0043] In some embodiments, as Figure 5 shown, the support member 33 includes a slide rail 331, a slide seat 332, a bolt 333, and a reinforcing rib 334. The slide rail 331 is fixedly connected to the bracket 31. The slide seat 332 is connected to the slide rail 331 through the bolt 333. The reinforcing rib 334 is fixedly connected to the slide seat 332. The reinforcing rib 334 increases the contact area with the ground and prevents the storage tank body 1 from tipping over.

[0044] Further, the slide rail 331 is processed into a strip shape. The slide seat 332 moves along the vertical direction of the slide rail 331. The bolt 333 is used to fix the position of the slide seat 332 on the slide rail 331. The reinforcing rib 334 is triangular to prevent the storage tank body 1 from tipping over.

[0045] In some embodiments, as Figure 5 shown, a threaded sleeve 331a is fixedly connected in the slide rail 331, and the threaded sleeves 331a are evenly distributed along the slide rail 331.

[0046] Furthermore, internal threads are machined in the threaded sleeve 331a to facilitate connection with the bolt 333.

[0047] In some embodiments, as Figure 1 shown, a blanking shell 11 is installed at the bottom of the storage tank body 1. A hemispherical cavity is formed in the blanking shell 11, and a flange pipe 12 is fixedly connected to the bottom of the blanking shell 11.

[0048] Furthermore, the blanking shell 11 is designed in a hemispherical shape to facilitate the PVC raw materials to converge into the flange pipe 12 for dropping, and the design of the flange pipe 12 facilitates connection with an external pipeline.

[0049] In some embodiments, as Figure 4 shown, a guiding rod 231 is fixedly connected to the rack plate 23, and the guiding rod 231 is inserted into a through groove at the bottom of the bearing frame 22.

[0050] Furthermore, the design of the guiding rod 231 enables the rack plate 23 to move only in the vertical direction.

[0051] In some embodiments, as Figure 2 shown, a rotary knob 255a is fixedly connected to one end of the positioning pin 255 away from the ferrule 254, and strip-shaped lines are formed on the rotary knob 255a.

[0052] Furthermore, the design of the rotary knob 255a is used to rotate the positioning pin 255, and the design of the strip-shaped lines increases the friction of the rotary knob 255a.

[0053] In some embodiments, as Figure 4 shown, the telescopic member 24 is a hydraulic cylinder.

[0054] Furthermore, the telescopic member 24 is designed as a hydraulic cylinder, making the lifting of the rack plate 23 simpler and more convenient.

[0055] The working principle of the present application will be described below with a preferred embodiment:

[0056] The telescopic member 24 is activated to drive the rack plate 23 to move upward along the top through groove of the carrier 22. The rack plate 23 drives the storage tank body 1 to move upward through the connecting plate 21. At this time, the rack plate 23 drives the gear 253 to rotate in the mounting seat 251 through the rotating shaft 252. After adjusting the use height of the storage tank body 1, then rotate the positioning pin 255 in the mounting seat 251 and insert it into the corresponding card slot in the ferrule 254. Since the gear 253 and the rack plate 23 are in a meshed state, the gear 253 brakes the rack plate 23 to prevent the rack plate 23 from accidentally moving downward. At this time, the storage tank body 1 can add PVC raw materials into PVC production equipment at different heights. The overall mechanism is driven by the universal wheels 32 and the bracket 31 to move to a position close to other PVC production equipment. Then, the sliding seat 332 is adjusted to move vertically downward along the slide rail 331. Furthermore, the reinforcing rib 334 on the sliding seat 332 contacts the ground, and the bolt 333 is used to fix the position of the sliding seat 332 on the slide rail 331 to prevent the storage tank body 1 from tipping over.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
