Description

Technical Field

[0001] This utility model relates to the technical field of automatic weighing and batching devices, specifically to an automatic weighing and batching device for resin latex liquid. Background Technology

[0002] Resin latex is a latex system with polymer resin as the main component, dispersed in an aqueous medium. It is formed by emulsion polymerization, in which resin particles are uniformly dispersed in water in the form of tiny particles, forming a milky white liquid. Automatic weighing and dispensing devices are used when weighing and dispensing resin latex.

[0003] The current automatic weighing and dispensing device for resin latex has a problem during use: the resin latex inside the storage container is not in a constant flow state during weighing and dispensing, which can cause the resin latex inside the storage container to solidify, potentially affecting the normal operation of the device.

[0004] The existing treatment method usually involves adding a stirring rod inside the storage container to stir the resin latex liquid inside the storage container, thereby reducing the probability of the resin latex liquid inside the storage container solidifying.

[0005] However, the above-mentioned processing method only uses a single stirring rod to stir the resin latex inside the storage container, which makes it difficult to achieve comprehensive stirring of the resin latex inside the storage container. As a result, the resin latex near the inner wall of the storage container is prone to solidify on the inner wall of the storage container, resulting in a reduction of the storage space inside the storage container. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides an automatic weighing and dispensing device for resin latex liquid. This solves the problem that existing automatic weighing and dispensing devices for resin latex liquid only use a single stirring rod to stir the resin latex liquid inside the storage container, making it difficult to achieve comprehensive stirring of the resin latex liquid inside the storage container. As a result, the resin latex liquid near the inner wall of the storage container tends to solidify on the inner wall of the storage container, causing a reduction in the internal storage space of the storage container.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: an automatic weighing and dispensing device for resin latex liquid, comprising a shell and a storage container, the storage container being installed on the upper side of the shell, the upper side of the storage container being connected to a feed inlet, the feed inlet being able to connect to a conveying device through an external pipe, and further comprising a slide rail, a toothed plate, a mounting frame, a stirring rack, a shovel plate, a rotating shaft, and a transmission gear. Two slide rails are installed on the upper part of the inner wall of the storage container, and a toothed plate is horizontally slidably connected to the slide rails. The mounting frame is installed on the lower side of the toothed plate and moves synchronously with the toothed plate. Multiple stirring racks are installed inside the mounting frame, and the stirring racks move synchronously with the mounting frame. Shovel plates are installed on both sides of the mounting frame, and the shovel plates move synchronously with the mounting frame. The rotating shaft is rotatably mounted on the upper side of the storage container through two vertical plates. A driving component for driving the rotating shaft to rotate is provided on one of the vertical plates on one side, the driving component being a forward and reverse reversing motor. A transmission gear is sleeved on the rotating shaft, and the transmission gear meshes with the two toothed plates.

[0010] As a preferred embodiment of the automatic weighing and dispensing device for resin latex liquid described in this utility model, in order to achieve sliding limit of the toothed plate and ensure the stability of the toothed plate during sliding, the slide rail is shaped like a square, and the two slide rails are symmetrically arranged on the upper part of the inner wall of the liquid storage container.

[0011] As a preferred embodiment of the automatic weighing and batching device for resin latex liquid described in this utility model, in order to ensure that the movement of the two toothed plates does not affect each other, the two toothed plates are both L-shaped, with the toothed rack on one toothed plate facing upwards and the toothed rack on the other toothed plate facing downwards, and the width of one toothed plate being greater than the width of the other toothed plate.

[0012] As a preferred embodiment of the automatic weighing and batching device for resin latex liquid described in this utility model, in order to realize the reciprocating movement of the horizontal position of the stirring frame, two movable openings are provided on the upper side of the liquid storage container, and the width of the two movable openings is adapted to the width of the corresponding toothed plate.

[0013] In a preferred embodiment of the automatic weighing and dispensing device for resin latex liquid described in this utility model, in order to achieve positioning of the rotating shaft, a positioning component is provided on the upper side of one of the two sides of the upright plate.

[0014] In a preferred embodiment of the automatic weighing and dispensing device for resin latex liquid described in this utility model, an arc-shaped anti-slip pad is provided on the lower side of the positioning ring to ensure the positioning effect of the positioning ring on the rotating shaft.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides an automatic weighing and dispensing device for resin latex liquid, which has the following beneficial effects:

[0017] In this invention, compared to existing automatic weighing and dispensing devices for resin latex, which rely solely on a single stirring rod to agitate the resin latex inside the storage container, comprehensive agitation is difficult to achieve. This leads to the resin latex near the inner wall of the container easily solidifying, reducing the storage space. By combining a stirring frame and a shovel, the invention achieves both agitation of the resin latex inside the container and removal of resin latex from the inner wall. The reciprocating horizontal movement of the stirring frame and shovel is achieved through the cooperation of a slide rail, toothed plate, mounting frame, rotating shaft, and transmission gears. Therefore, this automatic weighing and dispensing device for resin latex reduces the probability of solidification inside the storage container, ensuring normal operation. The stirring frame and shovel provide comprehensive agitation of the resin latex, enhancing the agitation effect and further reducing the probability of solidification. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] Please see Figures 1 to 5 This embodiment proposes an automatic weighing and dispensing device for resin latex liquid, including a shell 1 and a storage container 2. The storage container 2 is installed on the upper side of the shell 1. It also includes a slide rail 3, a toothed plate 4, a mounting frame 5, a stirring rack 6, a shovel plate 7, a rotating shaft 8, and a transmission gear 9. Compared with existing automatic weighing and dispensing devices for resin latex liquid, which only use a single stirring rod to stir the resin latex liquid inside the storage container, it is difficult to achieve comprehensive stirring of the resin latex liquid inside the storage container. This results in the resin latex liquid near the inner wall of the storage container easily solidifying on the inner wall, causing a reduction in the internal storage space of the storage container. In this embodiment, by stirring... The cooperation of the mixing rack 6 and the shovel plate 7 enables the stirring of the resin latex inside the storage container 2 and the removal of the resin latex from the inner wall of the storage container 2, reducing the probability of the resin latex solidifying inside the storage container 2 and ensuring the normal operation of the device. Through the cooperation of the slide rail 3, toothed plate 4, mounting frame 5, rotating shaft 8 and transmission gear 9, the reciprocating horizontal movement of the mixing rack 6 and the shovel plate 7 is realized, so that the mixing rack 6 and the shovel plate 7 can thoroughly stir the resin latex inside the storage container 2, enhancing the stirring effect of the resin latex and further reducing the probability of the resin latex solidifying inside the storage container 2.

[0028] like Figure 2As shown, the lower side of the storage container 2 is connected to a feeding hopper 10, and the bottom end of the feeding hopper 10 is connected to a first solenoid valve 11. A weighing instrument 12 is installed on the inner bottom wall of the outer shell 1. A support frame 13 is placed on the upper side of the weighing instrument 12, and a weighing hopper 14 is installed on the upper side of the support frame 13. The lower side of the weighing hopper 14 is connected to a second solenoid valve 15, and the bottom end of the second solenoid valve 15 is connected to an external pipe. A control panel 16 is installed on the outer side of the outer shell 1. When weighing and dispensing, the resin latex liquid inside the storage container 2 enters the weighing hopper 14 through the feeding hopper 10 and the first solenoid valve 11. The weighing instrument 12 weighs the resin latex liquid entering the weighing hopper 14. When the weight reaches the required dispensing weight, the control panel 16 controls the first solenoid valve 11 to close and controls the second solenoid valve 15 to open. The weighed resin latex liquid is dispensed through the second solenoid valve 15, thereby realizing the automated heavy dispensing of resin latex liquid.

[0029] like Figure 3 As shown, two slide rails 3 are installed on the upper part of the inner wall of the liquid storage container 2. The slide rails 3 are U-shaped and are symmetrically arranged on the upper part of the inner wall of the liquid storage container 2. The slide rails 3 can slide and limit the toothed plate 4, ensuring the stability of the toothed plate 4 when sliding. The toothed plate 4 is horizontally slidably connected to the slide rail 3. Both toothed plates 4 are L-shaped. The rack on one toothed plate 4 is set upwards, and the rack on the other toothed plate 4 is set downwards. The width of one toothed plate 4 is greater than the width of the other toothed plate 4. Two movable openings are provided on the upper side of the container 2. The width of each movable opening is adapted to the width of the corresponding toothed plate 4. When the mounting frame 5 is moved by the toothed plate 4, the toothed plate 4 moves inside the movable opening. The mounting frame 5 is installed on the lower side of the toothed plate 4. Multiple stirring racks 6 are installed inside the mounting frame 5. Shovels 7 are installed on both sides of the mounting frame 5. The rotating shaft 8 is rotatably mounted on the upper side of the liquid storage container 2 via two vertical plates. One of the vertical plates on one side is provided with a driving component for driving the rotating shaft 8 to rotate, such as... Figure 4 As shown, a transmission gear 9 is sleeved on the rotating shaft 8. The transmission gear 9 meshes with two toothed plates 4. The cooperation of the slide rail 3, toothed plates 4, mounting frame 5, rotating shaft 8 and transmission gear 9 enables the reciprocating horizontal movement of the stirring frame 6 and the shovel plate 7, so that the stirring frame 6 and the shovel plate 7 can thoroughly stir the resin latex liquid inside the storage container 2, enhance the stirring effect of the resin latex liquid, and thus reduce the probability of the resin latex liquid solidifying inside the storage container 2.

[0030] like Figure 4 As shown, a positioning component is provided on the upper side of one of the upright plates on both sides, such as... Figure 5As shown, the positioning assembly includes a mounting plate 101, an electric push rod 102, and a positioning ring 103. An arc-shaped anti-slip pad is provided on the lower side of the positioning ring 103. The arc-shaped anti-slip pad increases the friction between the positioning ring 103 and the rotating shaft 8, thereby enhancing the positioning effect of the positioning ring 103 on the rotating shaft 8. The positioning assembly can position the rotating shaft 8, so that when the resin latex liquid inside the liquid storage container 2 does not need to be stirred, the stirring rack 6 is in a stationary state.

[0031] Working principle:

[0032] When it is necessary to stir the resin latex liquid inside the storage container 2, the electric push rod 102 is activated. The telescopic end of the electric push rod 102 retracts, causing the positioning ring 103 to move upward, thus canceling the positioning of the rotating shaft 8 by the positioning ring 103. After cancellation, the forward and reverse motor is activated, causing the rotating shaft 8 to reciprocate. The rotating shaft 8 drives the transmission gear 9 to reciprocate, and the transmission gear 9 drives the toothed plate 4 to slide along the slide rail 3. The toothed plate 4 drives the mounting frame 5 to reciprocate inside the storage container 2. The mounting frame 5 drives the stirring frame 6 and the shovel plate 7 to reciprocate. The stirring frame 6 stirs the resin latex liquid inside the storage container 2, and the shovel plate 7 removes the resin latex liquid from the inner wall of the storage container 2, thereby ensuring the fluidity of the resin latex liquid inside the storage container 2.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
