Description

Technical Field

[0001] This utility model relates to the field of vacuum feeding technology, specifically a centralized vacuum feeding system for PVC sheet production. Background Technology

[0002] In the production process of PVC sheets, the supply of raw materials is a key link to ensure continuous and stable production, which directly affects the quality of the sheets and production efficiency.

[0003] From the perspective of raw material processing, the production of PVC sheets often requires the mixing of multiple raw materials in proportion. In traditional systems, mixing often relies on manual premixing or simple stirring, which can easily lead to uneven mixing of materials and affect the physical properties of the subsequent sheets. At the same time, the feeding of mixed materials and single raw materials often need to be carried out separately, and the switching between equipment is cumbersome and it is difficult to achieve centralized processing.

[0004] In terms of material supply efficiency, traditional decentralized material supply relies on frequent manual operations, which is labor-intensive and has a low degree of matching between manual rhythm and production line, making it easy for material supply to be interrupted or piled up, which seriously restricts production continuity.

[0005] From the perspective of equipment adaptability, existing feeding equipment has a single function and is mostly designed for specific raw materials or mixing ratios. When it is necessary to switch between mixed feeding and single raw material feeding, such as temporarily adding a certain additive, the equipment needs to be adjusted or even replaced in a complicated manner. It has poor flexibility and cannot meet the needs of efficient and flexible production. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides the following technical solution: a centralized vacuum feeding system for PVC sheet production, comprising:

[0007] The vacuum section includes a vacuum tube one, a vacuum discharge shell fixedly mounted on the vacuum tube one, a vacuum discharge roller rotatably mounted at the bottom of the vacuum discharge shell, a vacuum discharge pipe for discharging material below the vacuum discharge roller, a vacuum filter screen mounted at the top of the vacuum discharge shell, a vacuum tube two mounted at the top of the vacuum discharge shell, the other end of the vacuum tube two mounted on the vacuum outer shell, and a vacuum drive shaft and a vacuum driven shaft rotatably mounted inside the vacuum outer shell, the vacuum drive shaft and the vacuum driven shaft being slidably engaged;

[0008] The stirring part is detachably mounted on the first vacuum tube. The stirring part includes a stirring discharge pipe detachably mounted on the first vacuum tube. The stirring discharge pipe is located at the bottom of the stirring shell. A stirring shaft is rotatably mounted inside the stirring shell.

[0009] Furthermore, the side wall of the top of the mixing shell is provided with multiple mixing inlets, the mixing shaft is fixedly mounted on the output shaft of the mixing motor, the mixing motor is fixedly mounted on the mixing top cover, and the mixing top cover is fixedly mounted on the top of the mixing shell.

[0010] Furthermore, the vacuum tube is provided with a feeding part, which includes a feeding shell. The bottom of the feeding shell is fixedly disposed on the vacuum tube and communicates with the vacuum tube.

[0011] Furthermore, the top of the feed housing is provided with a rotatable feed top cover, and a sealing gasket is provided between the feed top cover and the feed housing.

[0012] Furthermore, the feed top cover is sealed to the feed housing by a feed nut.

[0013] Furthermore, a feeding and distributing roller is rotatably mounted on the bottom of the feeding housing, and the feeding and distributing roller is fixedly mounted on the feeding motor.

[0014] Furthermore, the vacuum driven shaft is fixedly mounted on the output shaft of the vacuum motor.

[0015] The advantages of this utility model compared with the prior art are:

[0016] 1. Improves the uniformity of raw material mixing and ensures the quality of the boards; This utility model is equipped with an independent stirring unit, which drives the stirring shaft to rotate through a stirring motor, and can fully mix various raw materials put into the stirring shell. Compared with traditional manual premixing or simple stirring, it can significantly improve the uniformity of material mixing, avoid physical performance defects (such as uneven strength, differences in weather resistance, etc.) in the subsequent production of PVC boards due to uneven mixing, and ensure the stability of board quality from the source.

[0017] The mixing unit has multiple mixing inlets that can simultaneously feed different raw materials. Combined with continuous mixing action, it ensures that all kinds of raw materials are efficiently blended before entering the feeding stage, providing a high-quality mixed raw material base for subsequent production.

[0018] 2. Achieve centralized material supply and improve production continuity and efficiency; This utility model integrates the mixing section, feeding section and vacuum section on the base plate to form a centralized material supply unit. It eliminates the need for decentralized material supply operations for mixed materials and single raw materials, reduces the cumbersome process of switching between equipment, and achieves centralized processing of the material supply process.

[0019] Material conveying is accomplished using the negative pressure of the vacuum section, replacing the traditional decentralized feeding mode that requires frequent manual operation, thus reducing labor intensity. Simultaneously, the rhythm of vacuum feeding can be precisely matched to the production line through equipment parameter adjustment, effectively avoiding feeding interruptions or accumulation, significantly improving production continuity, and ultimately increasing overall production efficiency.

[0020] 3. Enhanced equipment adaptability and operational flexibility: The mixing unit and vacuum tube of this invention are detachably connected. When switching from mixed feeding to single-raw material feeding, the mixing unit can be easily removed or left unloaded, and single-raw material (such as temporarily added additives) can be fed through the feeding unit. Conversely, reinstalling the mixing unit restores the mixed feeding mode. No complex adjustments or replacements are required, making operation simple and quick.

[0021] The feeding and distributing rollers in the feeding section are driven by the feeding motor, which can feed materials in an orderly manner. Combined with the negative pressure conveying of vacuum feeding, it can not only meet the batch feeding of mixed materials, but also adapt to the precise addition of single raw materials. The function of the equipment is no longer limited to specific raw materials or mixing ratios, and can flexibly meet diverse production needs. Attached Figure Description

[0029] like Figures 1 to 3 As shown, the stirring unit 1 is detachably mounted on the vacuum tube 301. The stirring unit 1 includes a stirring motor 101, a stirring shaft 102, a stirring top cover 103, a stirring outer shell 104, a stirring inlet 105, and a stirring discharge pipe 106. The stirring discharge pipe 106 is detachably mounted on the vacuum tube 301. A sleeve is provided at the end of the vacuum tube 301, and the inner wall of the sleeve is threaded. The thread on the inner wall of the sleeve is detachably engaged with the thread on the outer wall of the end of the stirring discharge pipe 106.

[0031] like Figures 1 to 3 As shown, the working principle of the centralized vacuum feeding system for PVC sheet production disclosed in this utility model is as follows:

[0032] When stirring is required;

[0033] Different materials are fed into the mixing shell 104 through multiple mixing inlets 105. The mixing motor 101 is turned on, and its rotation drives the mixing shaft 102 to rotate. The rotation of the mixing shaft 102 stirs the different materials within the mixing shell 104, ensuring thorough mixing. During feeding, the vacuum motor 309 is turned on, driving the vacuum driven shaft 307 to rotate. The rotation of the vacuum driven shaft 307, in turn, drives the vacuum drive shaft 306 to rotate. The rotation of the vacuum drive shaft 306 and vacuum driven shaft 307 causes air to flow within the vacuum tube 2 303, the vacuum discharge shell 308, and the vacuum tube 1 301, creating negative pressure. Under the combined effects of gravity and negative pressure, the mixing shell... The mixed material inside shell 104 enters vacuum tube 1 301 from the mixing discharge pipe 106. It is carried by the flowing air to vacuum discharge shell 308. After being filtered by vacuum filter 302 and under the action of gravity, the air enters vacuum shell 310 from vacuum tube 2 303 and is discharged from the bottom of vacuum shell 310. The material falls into the bottom of vacuum discharge shell 308. When the material accumulates to a certain amount, vacuum motor 309 is turned off. At this time, the air in vacuum tube 1 301, vacuum discharge shell 308 and vacuum tube 2 303 no longer flows. Vacuum discharge shell 308 is turned on. Vacuum discharge shell 308 rotates and drives vacuum discharge roller 304 to discharge the material at the bottom of vacuum discharge shell 308 from vacuum discharge pipe 305, thus completing the feeding.

[0034] When feeding materials separately;

[0035] The operator can rotate the sleeve to remove the mixing discharge pipe 106 from the vacuum tube 301 or not put any material into the mixing shell 104.

[0036] The operator removes the feed nut 202 by turning it, simultaneously opening the feed top cover 201. Material is then fed into the feed housing 203. The vacuum motor 309 is then turned on, causing the vacuum driven shaft 307 to rotate. This rotation, in turn, drives the vacuum drive shaft 306. The rotation of the vacuum drive shaft 306 and vacuum driven shaft 307 causes air to flow within the vacuum tube 2 303, vacuum discharge housing 308, vacuum tube 1 301, mixing discharge pipe 106, and mixing housing 104, creating negative pressure. At this point, the feed motor 205 is turned on, causing the feed distribution roller 204 to rotate. The rotation of the feed distribution roller 204 then pushes the feed housing 203... The material is orderly fed into the vacuum tube 301 and carried by the flowing air into the vacuum discharge shell 308. After being filtered by the vacuum filter 302 and under the action of gravity, the air enters the vacuum shell 310 from the vacuum tube 303 and is discharged from the bottom of the vacuum shell 310. The material falls into the bottom of the vacuum discharge shell 308. When the material accumulates to a certain amount, the vacuum motor 309 is turned off. At this time, the air in the stirring shell 104, stirring discharge pipe 106, vacuum tube 301, vacuum discharge shell 308, and vacuum tube 303 no longer flows. The vacuum discharge shell 308 is turned on, and the rotation of the vacuum discharge shell 308 drives the vacuum discharge roller 304 to discharge the material at the bottom of the vacuum discharge shell 308 from the vacuum discharge pipe 305, completing the individual feeding.
