Description

Technical Field

[0001] This utility model relates to the field of material collection devices, and in particular to a material collection device for weighing and collecting paste resin latex residue. Background Technology

[0002] PVC paste resin latex residue is a byproduct generated during the production of PVC paste resin. It mainly originates from emulsion or micro-suspension polymerization processes. Its formation is related to residual emulsifiers, unreacted vinyl chloride monomer (VCM), and polymerization byproducts during production.

[0003] In the production of paste resin, latex residue needs to be centrally processed through a collection device. Existing devices typically include storage containers, conveying pipelines, and discharge outlets for the temporary storage and transfer of residue. During the collection process, solid-liquid separation is first achieved through a sedimentation process. In the production or processing of paste resin, the slurry undergoes sedimentation, causing solids such as starch and residue to separate from the liquid. After sedimentation, the clear liquid on top needs to be scooped out, and the remaining solids (including residue) are further processed.

[0004] In summary, existing resin latex residue collection devices generally lack a weighing and feeding structure, requiring manual weighing or additional equipment assistance, which increases labor and time costs. Furthermore, the amount of residue fed cannot be monitored in real time, affecting the stability of subsequent process proportions. Utility Model Content

Detailed Implementation

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0020] like Figures 1 to 4 As shown in the figure, the present invention provides a weighing and feeding collection device for paste resin latex residue, which includes a collection component 1 and a weighing and feeding component 2 disposed above the collection component 1. The collecting assembly 1 includes a base 11, a half gear 15 is rotatably connected to the bottom of the inner cavity of the base 11, one end of the half gear 15 is meshed with a drive gear 16, and a shifting rod 21 is fixedly connected to the top of the drive gear 16. The weighing and feeding assembly 2 includes a lifting rod 22. A retaining ring 213 is provided on one side of the lifting rod 22. A shifting plate 25 is rotatably connected inside the retaining ring 213. A connecting rod 221 extends upward from the top of the lifting rod 22. A limiting plate 24 is fixedly connected to the top of the connecting rod 221. Feeding ports 250 are symmetrically arranged at both ends of the bottom of the shifting plate 25. A weighing plate 26 is provided at the bottom of the feeding port 250. The lifting rod 22, through the meshing action of the side teeth 220 and the first gear 14, drives the shifting plate 25, which is engaged by the retaining ring 213 on the side of the lifting rod 22 via the retaining groove 23, to rise and fall at the bottom of the feeding cylinder 210, changing the capacity between the top of the weighing plate 26 and the feeding cylinder 210. This allows for adjusting the amount of slag that the feeding cylinder 210 can hold when it is necessary to increase or collect the slag. The inlet 212 is used for… The material slag is conveyed from the outside to the inside of the conveying trough 211. Since one end of the limiting plate 24 is provided with an inclined surface, when the material slag enters the feeding cylinder 210 from the inside of the conveying trough 211, the weighing structure provided on the surface of the weighing plate 26 can record the amount of material discharged from the conveying trough 211. When the weight of the material slag reaches the set value, the control unit provided at the bottom of the base 11 can drive the drive source provided at the bottom of the base 11 to drive the half gear 15 to rotate. Since the half gear 15 is only provided with a half-tooth structure, when the tooth structure meshes with the drive gear 16, it drives the shift rod 21 to rotate, so that the weighing plate 26 provided at the bottom of the feeding port 250 rotates to the top of the conveyor belt 17. Since the limiting block 260 drives the weighing plate 26 to rotate downward along the inclined surface of the limiting plate 24, the material slag inside the feeding port 250 and the feeding cylinder 210 falls to the surface of the conveyor belt 17 and is transported to the external collection box for collection.

[0021] The bottom of the shifting plate 25 is provided with a slot 23, and the lifting rod 22 is engaged with the bottom of the shifting plate 25 through the slot 23. One end of the limiting plate 24 is provided with an inclined surface. A conveying groove 211 is provided above the shifting rod 21. The bottom ends of the conveying groove 211 are symmetrically provided with a feeding cylinder 210. The feeding cylinder 210 is slidably connected to the inside of the feeding port 250. The feeding port 250, which is opposite to the conveyor belt 17, is always connected to the conveying groove 211. When the feeding cylinder 210 rotates, the connection between the conveying groove 211 and the feeding port 250 is lost.

[0022] One end of the weighing plate 26 extends into a limiting block 260, the top of which abuts against the bottom of the limiting plate 24. The top of the conveying groove 211 is provided with an inlet 212. The bottom of the shifting rod 21 is fitted with a first fixing ring 12, which is fixedly connected to the inner wall of the base 11. The bottom of the lifting rod 22 is fitted with a second fixing ring 13, which is fixedly connected to the inner wall of the base 11. The connection between the second fixing ring 13 and the base 11 is located at the drive motor, which can drive the lifting rod 22 to rise and fall under the control of the control unit.

[0023] The base 11 has a first gear 14 arranged horizontally in its inner cavity. The lifting rod 22 has teeth 220 on its side. The second fixing ring 13 meshes with the side of the lifting rod 22 through the teeth 220. A conveyor belt 17 is provided at one end of the base 11. The bottom of the discharge port 250 is located above one end of the conveyor belt 17. The bottom of the half gear 15 has a limiting groove 150. The bottom of the drive gear 16 has symmetrical clearance grooves 160. The arc surfaces at both ends of the clearance groove 160 are complementary to the limiting groove 150. Since the half gear 15 only has a half-tooth structure, the end without the tooth structure can ensure that the rotation of the half gear 15 does not deflect under the interlocking action of the limiting groove 150 and the clearance groove 160. Each rotation of the half gear 15 can drive the discharge cylinder 210 connected to the top of the drive gear 16 by the shifting rod 21 to rotate 180 degrees.

[0024] Working principle: When it is necessary to weigh and collect the slag, since one end of the limiting plate 24 is provided with an inclined surface, after the slag enters the discharge cylinder 210 from the inside of the conveying trough 211, the weighing structure on the surface of the weighing plate 26 can record the amount of material discharged from the conveying trough 211. When the weight of the slag reaches the set value, the control unit at the bottom of the base 11 can cause the drive source at the bottom of the base 11 to drive the half gear 15 to rotate. When the tooth structure at one end of the half gear 15 meshes with the drive gear 16, it drives the shift rod 21 to rotate, thereby causing the weighing plate 26 at the bottom of the discharge port 250 to rotate onto the upper part of the conveyor belt 17. When the limiting block 260 moves downward along the inclined surface of the limiting plate 24, it drives the weighing plate 26 to rotate, causing the material and slag inside the discharge port 250 and the discharge cylinder 210 to fall onto the surface of the conveyor belt 17 and be transported to the external collection box for collection. When the amount of material and slag to be weighed needs to be changed, the lifting rod 22 can drive the shifting plate 25, which is engaged by the slot 23 inside the retaining ring 213 on the side of the lifting rod 22, to rise and fall at the bottom of the discharge cylinder 210, changing the capacity between the top of the weighing plate 26 and the discharge cylinder 210, so as to increase or decrease the amount of material and slag to be collected.

[0025] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
