Description

Technical Field

[0001] This utility model belongs to the field of papermaking equipment technology, and more specifically, it relates to a starch quantitative feeding device. Background Technology

[0002] The main reasons for adding starch during papermaking include: improving paper quality: starch can significantly improve the texture and smoothness of paper, making it more suitable for printing and writing; increasing production efficiency: starch can increase pulp utilization and reduce waste, thereby improving production efficiency; enhancing paper strength: starch acts as an internal sizing agent in finished paper, increasing its strength and durability; improving printing and writing performance: low-viscosity starches, such as oxidized starch, can be used as surface sizing agents, not only improving paper strength but also improving ink thinning during printing and writing; manufacturing high-grade paper: modified starch is used as a binder in pigment coating to produce smooth, white, high-grade paper, meeting the demands of the high-end market; surface sizing: starch plays an important role in surface sizing, improving the sizing effect of paper and enhancing its water resistance and durability. The amount of starch added directly affects various paper properties. Currently, most starch addition in papermaking is done manually, therefore a starch quantitative feeding device is needed to quantitatively add starch during papermaking. However, existing starch quantitative feeding devices can only quantitatively add starch to a single papermaking tank. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a starch quantitative feeding device to solve the problem that most existing technologies rely on manual addition and that existing starch quantitative feeding devices can only add starch quantitatively to a single papermaking tank.

[0004] This utility model discloses a starch quantitative feeding device, which is achieved by the following specific technical means:

[0005] A starch quantitative feeding device includes: a device shell; a feeding hopper is provided on the upper part of the device shell, a storage bin bottom plate is provided on the upper side inside the device shell, a discharge port is provided on the rear side of the storage bin bottom plate, a quantitative bin bottom plate is provided below the storage bin bottom plate, a discharge port is provided on the front side of the quantitative bin bottom plate, and a discharge positioning plate is provided on the front side below the discharge port.

[0006] Furthermore, the bottom plate of the storage silo is designed to be higher in the front and lower in the back, with a baffle plate on its upper side and a first electric telescopic rod on the front side of the baffle plate. The size of the baffle plate is just enough to block the discharge port.

[0007] Furthermore, the bottom plate of the quantitative silo is designed to be higher at the back and lower at the front, and the bottom plate is secured to the inside of the device housing on all four sides. A vibration motor is installed below the bottom plate of the quantitative silo.

[0008] Furthermore, the device housing above the discharge port has an opening groove inside, a discharge baffle is provided in the opening groove, a second electric telescopic rod is connected above the discharge baffle, the device housing below the discharge baffle has an opening groove, a baffle is provided in the opening groove, and a retractable member is provided below the baffle.

[0009] Furthermore, a rotating component is connected to the lower side of the device housing, a drive shaft is connected to the lower side of the rotating component, a rotary motor is connected below the drive shaft, and the rotary motor is located inside the motor housing.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This utility model sets the bottom plate of the storage silo to be higher in the front and lower in the back, which is conducive to feeding materials from the storage silo into the quantitative silo. When the quantitative silo is full of starch, the baffle plate blocks the feeding port and stops feeding starch.

[0012] 2. By incorporating a vibration motor, this invention facilitates both the compaction of starch within the quantitative silo and the efficient discharge of starch from the storage silo into the quantitative silo.

[0013] 3. By setting up a rotary motor, the device is placed between two sets of papermaking tanks, which can simultaneously add starch to the two papermaking tanks. Attached Figure Description

[0032] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0033] Example:

[0034] As attached Figure 1 To be continued Figure 5 As shown:

[0035] This utility model provides a starch quantitative feeding device, including: a device shell 1; a feeding hopper 2 is provided on the top of the device shell 1, a storage bin bottom plate 10 is provided on the upper side inside the device shell 1, a discharge port 1001 is provided on the rear side of the storage bin bottom plate 10, a quantitative bin bottom plate 9 is provided below the storage bin bottom plate 10, a discharge port 3 is provided on the front side of the quantitative bin bottom plate 9, a discharge positioning plate 5 is provided on the front side below the discharge port 3, an opening groove is provided inside the device shell 1 above the discharge port 3, a discharge baffle 4 is provided in the opening groove, a second electric telescopic rod 401 is connected above the discharge baffle 4, an opening groove is provided on the device shell 1 below the discharge baffle 4, a baffle 12 is provided in the opening groove, and a shrinking member 1201 is provided below the baffle 12.

[0036] Among them, such as Figure 2 As shown, the bottom plate 10 of the storage silo is designed to be higher in the front and lower in the back. A baffle plate 11 is provided on its upper side. A first electric telescopic rod 1101 is provided on the front side of the baffle plate 11. The size of the baffle plate 11 is just enough to block the discharge port 1001, which is conducive to the discharge of starch from the storage silo into the quantitative silo. When the starch in the quantitative silo is full, the baffle plate 11 blocks the discharge port 1001, and the starch discharge stops.

[0037] Among them, such as Figure 2As shown, the bottom plate 9 of the quantitative silo is set to a state where the back is higher than the front. The bottom plate 9 of the quantitative silo is clamped inside the outer shell 1 of the device on all four sides. A vibration motor 901 is provided below the bottom plate 9 of the quantitative silo. When starch enters the quantitative silo from the storage silo, it is beneficial to vibrate and compact the starch in the quantitative silo, and it is also beneficial to discharge the starch in the quantitative silo.

[0038] Among them, such as Figure 2 As shown, a rotating component 6 is connected to the lower side of the outer casing 1 of the device, and a drive shaft 801 is connected to the lower side of the rotating component 6. A rotary motor 8 is connected below the drive shaft 801, and the rotary motor 8 is located inside the motor casing 7. By placing the device between two sets of papermaking tanks, starch can be added to both papermaking tanks simultaneously.

[0039] The specific usage and function of this embodiment are as follows:

[0040] In this invention, starch is fed into the storage bin through the feed hopper 2. The starch falls into the metering bin through the discharge port 1001 on the bottom plate 10 of the storage bin. Under the action of the vibration motor 901, the bottom plate 9 of the metering bin vibrates and compacts the starch in the metering bin. When the metering bin is full of starch, the baffle plate 11 blocks the discharge port 1001, and the starch in the storage bin no longer falls into the metering bin. At the same time, the discharge baffle 4 opens, and the starch falls into the papermaking pool through the discharge positioning plate 5. After the starch in one side of the papermaking pool is added, the device moves to the rear under the action of the rotary motor 8 to add starch to the other side of the papermaking pool.

[0041] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.
