Description

Technical Field

[0001] This application relates to the field of latex paint production equipment technology, and in particular to a filling structure for latex paint production. Background Technology

[0002] Latex paint is a water-based coating, primarily composed of emulsions, pigments, fillers, water, and additives. It also has a low viscosity. The filling of latex paint is typically carried out using automated filling production lines. Existing latex paint filling production lines usually consist of a filling machine, a conveyor, and electrical control equipment. The conveyor transports empty cans to the filling machine, which then controls the filling machine to inject paint into the cans.

[0003] To address the issue of material splashing during the filling process in existing latex paint filling structures, Chinese patent CN202322030748.3 discloses a latex paint filling device. This device mainly involves adding a splash guard to the filling port of the filling machine to shield the material splashing at the outlet of the filling machine during the filling process.

[0004] While existing latex paint filling structures can prevent material from splashing during filling by adding a splash guard at the filling port, there are two problems during the filling process. First, the material adhering to the inside of the splash guard cannot fall effectively, resulting in material waste. Second, when the filling machine is idle after filling, the material remaining on the inner wall of the discharge port can easily fall under its own weight, making the filling equipment quite dirty and messy. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a latex paint production filling structure that can both blow away and clean the material adhering to the inner wall of the splash guard, and seal the outlet of the idle filling machine after filling, preventing the material from falling from the outlet of the filling machine under its own weight.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] A latex paint production filling structure includes a conveyor base, a filling machine mounted on one side of the upper end of the conveyor base, a filling pipe mounted at the filling port of the filling machine, a splash guard mounted at the lower part of the filling pipe, a spraying mechanism mounted on the upper side of the splash guard, and two sealing mechanisms symmetrically mounted on both sides of the splash guard. The spraying mechanism includes an air pump, a connecting pipe, an annular spray nozzle, and spray heads. The air pump is mounted on the upper part of one side wall of the filling machine, the connecting pipe is connected to the air outlet of the air pump, the annular spray nozzle is embedded in the upper part of the splash guard, and the spray heads are evenly distributed in a ring on the lower side of the annular spray nozzle. The sealing mechanism includes an installation sleeve, an electric telescopic rod, and a sealing block. The installation sleeve is mounted on the outer wall of the splash guard and communicates with the interior of the splash guard, the electric telescopic rod is mounted inside the installation sleeve, and the sealing block is connected to the telescopic part of the electric telescopic rod.

[0008] Optionally, four locking bolts are installed at the sleeve reserved at the top of the splash guard.

[0009] Optionally, the air pump is bolted to the filling machine, and the connecting pipe is inserted into both the air outlet of the air pump and the air inlet of the annular spray hood.

[0010] Optionally, the air outlet of the nozzle faces the inner wall of the splash guard, which is a conical cover.

[0011] Optionally, the fixing part of the electric telescopic rod is bolted to the mounting sleeve, and the telescopic part of the electric telescopic rod is bolted to the sealing block.

[0012] Optionally, the sealing block has a semi-circular structure, and the sealing block slides in conjunction with the mounting sleeve.

[0013] Optionally, an electrical control box is installed on the upper end of the conveyor seat on one side of the filling machine, and a capping mechanism is also installed at the capping station on the conveyor seat.

[0014] Optionally, the electrical control box is electrically connected to the capping mechanism, the conveying seat, the filling machine, the blowing mechanism, and the sealing mechanism.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] This utility model installs a spraying mechanism consisting of an air pump, a connecting pipe, an annular spray hood, and a nozzle on the splash guard. At the end of filling, the air pump and connecting pipe can blow air into the annular spray hood so that high-pressure gas can be sprayed along the inside of the splash guard through the nozzle, ensuring that the material adhering to the inner wall of the splash guard can fall smoothly and avoiding the waste of material adhering to the inner wall of the splash guard.

[0017] This invention features two sealing mechanisms symmetrically installed on both sides of the splash guard. These mechanisms consist of mounting sleeves, electric telescopic rods, and sealing blocks. When the device is idle after filling, the sealing blocks can be moved towards the outlet of the filling tube by the electric telescopic rods. This allows the sealing blocks in the two sealing mechanisms to seal the outlet of the filling tube, preventing the equipment from becoming dirty and messy due to the dripping of material adhering to the inner wall of the filling tube after filling.

Detailed Implementation

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] To better understand the technical solutions shown in the embodiments of this application, the working principle and anti-splashing measures of the existing latex paint production filling structure will be introduced first.

[0025] The existing latex paint production filling structure involves a conveyor transporting empty cans to the bottom of a filling machine, which then controls the filling machine to inject paint into the cans. At the same time, a splash guard is installed at the discharge port of the filling machine to prevent material from splashing onto the filling equipment during the filling process.

[0026] Please see Figures 1-4This application discloses a latex paint production filling structure, including a conveyor base 4. A filling machine 3 is installed on one side of the upper end of the conveyor base 4. A filling pipe 6 is installed at the filling port of the filling machine 3. A splash guard 5 is installed at the lower part of the filling pipe 6. A spraying mechanism 8 is installed on the upper side of the splash guard 5. Two sealing mechanisms 9 are symmetrically installed on both sides of the splash guard 5. The spraying mechanism 8 includes an air pump 81, a connecting pipe 82, an annular spray cover 83, and a nozzle 84. The air pump 81 is installed on the filling... On the upper part of one side wall of machine 3, the connecting pipe 82 is connected to the air outlet of air pump 81. The annular spray cover 83 is embedded in the upper part of the splash shield 5. The nozzles 84 are evenly distributed in a ring on the lower side of the annular spray cover 83. The sealing mechanism 9 includes a mounting sleeve 91, an electric telescopic rod 92 and a sealing block 93. The mounting sleeve 91 is installed on the outer wall of the splash shield 5 and communicates with the inside of the splash shield 5. The electric telescopic rod 92 is installed in the mounting sleeve 91. The sealing block 93 is connected to the telescopic part of the electric telescopic rod 92.

[0027] Specifically, when cleaning the material adhering to the inner wall of the splash guard 5 at the end of filling, air is first blown into the annular spray nozzle 83 through the air pump 81 and connecting pipe 82, and then the high-pressure gas is sprayed along the inside of the splash guard 5 through the nozzle 84 to ensure that the material adhering to the inner wall of the splash guard 5 can fall smoothly, thereby avoiding the waste of material adhering to the inner wall of the splash guard 5. After filling, in order to prevent the dripping of residual material at the outlet of the filling pipe 6 when the equipment is idle, the sealing block 93 is moved to the outlet of the filling pipe 6 by the electric telescopic rod 92, so that the outlet of the filling pipe 6 is sealed under the action of the sealing block 93 in the two sealing mechanisms 9, and the equipment is prevented from becoming dirty due to the dripping of material adhering to the inner wall of the filling pipe 6 after filling.

[0028] Please see Figure 1 and Figure 2 There are four locking bolts 7 installed at the pre-reserved sleeve at the top of the splash guard 5.

[0029] In one implementation, when installing the splash guard 5, the sleeve reserved at the top of the splash guard 5 is first inserted into the outside of the outlet of the filling pipe 6, and then the locking bolt 7 is tightened to achieve reliable installation of the splash guard 5 on the filling pipe 6.

[0030] Please see Figure 1 and Figure 3 The air pump 81 is bolted to the filling machine 3, and the connecting pipe 82 is plugged into the air outlet of the air pump 81 and the air inlet of the annular spray hood 83.

[0031] In one implementation, the connecting pipe 82 is inserted into both the air outlet of the air pump 81 and the air inlet of the annular spray hood 83. This allows the connecting pipe 82 to be reliably fixed between the air pump 81 and the annular spray hood 83, ensuring that the high-pressure gas blown out by the air pump 81 can smoothly enter the annular spray hood 83.

[0032] Please see Figure 2 The air outlet of nozzle 84 faces the inner wall of splash guard 5, which is a conical cover.

[0033] In one implementation, the nozzle 84 is mainly used to uniformly spray the high-pressure gas inside the annular spray cover 83 along the inner wall of the splash shield 5, so as to facilitate the removal of materials adhering to the inner wall of the splash shield 5.

[0034] Please see Figure 2 The fixed part of the electric telescopic rod 92 is bolted to the mounting sleeve 91, and the telescopic part of the electric telescopic rod 92 is bolted to the sealing block 93.

[0035] In one implementation, the fixing part of the electric telescopic rod 92 is bolted to the mounting sleeve 91, which allows the electric telescopic rod 92 to be reliably installed in the mounting sleeve 91. After the telescopic part of the electric telescopic rod 92 moves, the sealing block 93 can be synchronously slidably adjusted.

[0036] Please see Figure 2 and Figure 4 The sealing block 93 has a semi-circular structure and slides with the installation sleeve 91.

[0037] As one implementation method, the sealing block 93 is designed as a semi-circular structure, so that when two sealing blocks 93 are fitted together, they can form a disc structure, so as to conveniently use the disc structure formed by the two sealing blocks 93 to seal the outlet of the filling tube 6.

[0038] Please see Figure 1 An electrical control box 2 is installed on the upper end of the conveyor seat 4 on one side of the filling machine 3, and a capping mechanism 1 is also installed at the capping station on the conveyor seat 4.

[0039] In one implementation, the electric box serves as the control system for the entire filling structure, and the capping mechanism 1 is mainly used to cap and seal the material container after filling.

[0040] Please see Figures 1-3 The electrical control box 2 is electrically connected to the capping mechanism 1, the conveying seat 4, the filling machine 3, the blowing mechanism 8, and the sealing mechanism 9.

[0041] As one implementation method, the electrical control box 2 mainly coordinates the capping mechanism 1, the conveying seat 4, the filling machine 3, the blowing mechanism 8, and the sealing mechanism 9 by controlling the on and off of the circuit.

[0042] The specific working principle is as follows: During filling, the filling barrel is first placed on the conveyor seat 4 and positioned below the filling pipe 6. Then, under the action of the electrical control box 2, the filling machine 3 is started to achieve quantitative filling of latex paint. After filling, high-pressure gas is first blown into the annular spray cover 83 through the air pump 81 and the connecting pipe 82 so that the high-pressure gas is sprayed along the inner wall of the splash cover 5 through the nozzle 84, so as to blow off the latex paint adhering to the inner wall of the splash cover 5 and avoid the waste of latex paint. After the splash cover 5 is cleaned, a new filling barrel is replaced to continue the filling process. After filling, the filling barrel will be capped and sealed at the capping mechanism 1. When the filling equipment is idle, the sealing block 93 can be moved to the outlet of the filling pipe 6 by the electric telescopic rod 92 to seal the outlet of the filling pipe 6, so as to prevent the material remaining at the outlet of the filling pipe 6 from dripping after the filling equipment is used, and to ensure the cleanliness of the filling equipment.

[0043] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
