[0001] This utility model belongs to the field of paper tape production technology, and in particular relates to a starch adhesive preparation tank and a starch adhesive preparation system. Background Technology
[0002] Starch adhesive is used in the production of paper tape. The starch adhesive is usually prepared and stored in a starch adhesive preparation tank. Currently, small starch clumps are prone to appear in the starch adhesive during preparation. This is mainly because the starch is not evenly distributed in the water and forms clumps, which affects the gelatinization of the starch into a gel in hot water and forms small clumps. Although the starch preparation tank is equipped with a stirring device to accelerate the even distribution of starch in the water, dead zones still exist, leading to the appearance of small clumps. Utility Model Content

[0010] The powder distributor described in the above technical solution is an axial flow dustproof fan.
[0011] The beneficial effects of the above technical solution are: its structure is simple, and when the powder distributor is opened, it disperses the starch in the tank.
[0012] In the above technical solution, the feeding port is located in the middle of the upper part of the tank body, and the feeding port is funnel-shaped, with its larger opening end communicating with the tank body.
[0013] The beneficial effect of the above technical solution is that the starch is fully dispersed outward at the feeding port under the action of the powder distributor, and finally dissolved in water, thus obtaining a starch solution without lumps.

[0016] In the above technical solution, the discharge port is located at the lowest horizontal position at the bottom of the tank.
[0017] The beneficial effect of the above technical solution is that it allows the starch slurry inside the tank to be fully discharged to the outside.
[0018] The second objective of this invention is to provide a starch slurry preparation system with a simple structure that can fully disperse starch in water.
[0019] To achieve the above objectives, another technical solution of this utility model is as follows: a starch adhesive preparation system, comprising a hot water supply pipe, a hot water return pipe, and a starch adhesive preparation tank as described above. One end of the hot water supply pipe is connected to and communicates with one end of the heat exchange coil.

Detailed Implementation
[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0030] Example 1
[0031] like Figure 1As shown, this embodiment provides a starch slurry preparation tank, including a tank body 1 and a stirring element 2. The tank body 1 has a feeding port 11, a water inlet 12, and a discharge port 13. A heat exchange coil 14 is mounted on the inner wall of the tank body 1, with both ends of the heat exchange coil 14 extending outside the tank body 1. The stirring element 2 is mounted on the tank body 1, and its stirring part extends into the tank body 1. A powder distributor 15 is provided at the feeding port 11, which is used to add starch into the tank body 1. The starch is dispersed by the powder distributor 15, the water inlet 12 is used to add water into the tank 1, the discharge outlet 13 is used to discharge the starch slurry, and the heat exchange coil 14 is used to introduce hot fluid to keep the starch slurry in the tank 1 warm. In this way, hot water is added to the tank first, and then the starch is dispersed into the tank by the powder distributor. Under the stirring action of the agitator, the starch gelatinizes in the hot water to form a starch slurry. The heat exchange coil is used to keep the starch slurry in the tank warm to prevent it from solidifying.
[0032] In the above technical solution, a hopper 16 is provided at the feeding port 11, and the powder distributor 15 is provided at the junction of the feeding port 11 and the hopper 16. In this way, starch can be temporarily stored in the hopper, and the starch in the hopper is eventually distributed into the tank through the powder distributor.
[0033] In the above technical solution, a gate valve 17 is provided at the junction of the powder distributor 15 and the feeding port 11. The gate valve can open or close the junction of the powder distributor and the feeding port, thereby realizing the addition or suspension of starch in the tank.
[0034] The powder distributor 15 described in the above technical solution is an axial flow dustproof fan with a simple structure. When the powder distributor is turned on, it disperses the starch within the tank. In this embodiment, the axial flow dustproof fan is similar to the cooling fan of a computer host, where the fan blades disperse the starch within the tank as they rotate.
[0035] In the above technical solution, the feeding port 11 is located in the middle of the upper end of the tank body 1, and the feeding port 11 is funnel-shaped with its larger opening end communicating with the tank body 1. This allows the starch to be fully dispersed outward at the feeding port under the action of the powder distributor and finally dissolved in the water, thus obtaining a starch solution without lumps.
[0036] The stirring component 2 in the above technical solution includes a drive motor 21, a stirring shaft 22, and a stirring paddle 23. The stirring shaft 22 passes through the tank body 1, the stirring paddle 23 is located inside the tank body 1 and is mounted on the stirring shaft 22, and the drive motor 21 is located outside the tank body 1 and is connected to the stirring shaft 22 for transmission. Its structure is simple, and the stirring paddle rotates inside the tank under the drive of the drive motor to fully dissolve the starch into the hot water.
[0037] In the above technical solution, the discharge port 13 is located at the lowest horizontal position at the bottom of the tank body 1, so that the starch liquid in the tank body can be fully discharged outward.
[0038] In this embodiment, the stirring element can be set at the lower end of the tank, the stirring shaft vertically penetrates the middle of the lower end of the tank, the drive motor is set at the lower end of the tank, the discharge port is set at the edge of the lower end of the tank, and the stirring paddle is located in the middle of the heat exchange coil.
[0039] Example 2
[0040] like Figure 2 and Figure 3 As shown, this embodiment provides a starch slurry preparation system, including a hot water supply pipe 200, a hot water return pipe 300, and a starch slurry preparation tank 100 as described in Embodiment 1. One end of the hot water supply pipe 200 is connected to one end of the heat exchange coil 14, and the other end of the heat exchange coil 14 and the water inlet 12 are both connected to the hot water return pipe 300 through pipelines. Valves 400 are provided on both the hot water return pipe 300 and the water inlet 12. The structure is simple, so that the heat exchange coil is heated by hot water, and the hot water used to prepare the starch slurry in the tank is also supplied by the hot water supply pipe (and when hot water needs to be added to the tank, the tank can be preheated through the heat exchange coil first).
[0041] like Figure 3 As shown, the above technical solution also includes a controller 500, and the valves 400 are electric valves. Both valves 400 are electrically connected to the controller 500, so the controller can control the opening and closing of the valves to achieve heat preservation, or add hot water to the tank while preserving heat. In this embodiment, the controller 500 is an ARM series microcontroller.
[0042] like Figure 2 and Figure 3 As shown, the above technical solution also includes a flow monitoring device 600, which is installed at the water inlet 12 and electrically connected to the controller 500. This allows for monitoring of the amount of hot water added to the tank and automatic control of the amount of hot water added, thereby enabling precise batch production. In this embodiment, the flow monitoring device 600 can be a flow sensor.
[0043] In this embodiment, the controller can be installed in a control box next to the tank.
[0044] In this embodiment, the capacity of the tank is rated and the amount of material in the hopper is constant. Therefore, by setting a flow monitoring device, the amount of water added to the tank each time can be accurately controlled. For example, when the starch syrup preparation tank 100 needs to add hot water when preparing starch syrup (the amount of water added can be preset in the controller, and the controller controls the flow monitoring device and two valves 400 to complete the water addition to the tank. After the water addition is completed, hot water continues to be introduced through the heat exchange coil to keep the tank warm). After the water is added to the tank, the gate valve can be opened and the powder distributor 15 can be started to disperse the starch in the hopper into the tank.

However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
