Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, and in particular to a fully automatic anti-corrosion filling machine. Background Technology

[0002] With the increasing level of automation, fully automatic filling machines are now the primary method for filling liquid materials. Corrosion-resistant filling machines are specially designed for corrosive liquids. The biggest difference between them and ordinary filling machines is that all parts in direct contact with the material are made of stainless steel, Teflon (PTFE), or other corrosion-resistant materials. Because materials inevitably volatilize during filling, corrosive gases can contaminate the filling area over time, causing even parts not in direct contact with the corrosive material to be corroded, thus affecting their service life. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fully automatic anti-corrosion filling machine. This machine is applicable to the filling of highly corrosive materials in the chemical industry. It can effectively collect and treat volatile corrosive gases, preventing pollution to areas outside the equipment and extending the service life of the entire machine.

[0004] The technical solution to achieve the purpose of this utility model is:

[0005] A fully automatic anti-corrosion filling machine includes an outer frame with a closed door, a material box section mounted on top of the outer frame, and a conveying section extending horizontally through the outer frame. Above the conveying section are multiple filling sections connected to the material box section, and on the side are bottle clamping sections corresponding to the filling sections. Each filling section is equipped with multiple filling needles, and the nozzle of each filling needle is equipped with a suction hood for covering the bottle mouth. The side wall of the suction hood is equipped with an exhaust port, and the exhaust port is connected to an external waste gas treatment system through a pipe.

[0006] Furthermore, the lower part of the outer frame is sealed with a first partition, and the top is connected to an air inlet. Below the first partition, there is a main air intake pipe that penetrates the first partition and connects to the inner cavity of the outer frame. The outlet of the main air intake pipe is connected to an external exhaust gas treatment system.

[0007] Furthermore, a second partition is sealed above the first partition, and the surface of the second partition has evenly distributed air intake holes.

[0008] Furthermore, the lower part of the outer frame is fixedly equipped with a receiving part located directly below the filling part, and the receiving part is made of corrosion-resistant material.

[0009] Furthermore, the power element of the filling section and the bottle-carrying section is a cylinder, and the outer sealing cover of the cylinder is provided with an anti-corrosion cover.

[0010] Furthermore, a protective cylinder is filled between the corrosion-resistant cover and the cylinder to form a slightly positive pressure sealed space.

[0011] Furthermore, the inlet of the conveying section is provided with a photoelectric accessory for sensing the bottle, and multiple baffle assemblies corresponding to the filling section are provided on the side along the length direction. The baffle assemblies are located on the side of the filling section near the inlet of the conveying section.

[0012] Furthermore, the cutter block assembly includes a U-shaped mounting base fixed to the side of the conveying section. The mounting base is equipped with a cutter block cylinder. A cutter block located in the U-shaped cavity of the mounting base is connected to the piston rod of the cutter block cylinder. The distal end of the cutter block is provided with an inclined surface. Both the cutter block cylinder and the cutter block are covered with anti-corrosion covers.

[0013] Furthermore, the bottle-clamping section includes a support base located on the side of the conveying section. A telescopic cylinder is mounted on the top of the support base. A connecting plate is vertically mounted at the end of the piston rod of the telescopic cylinder. Guide rods are parallel to both ends of the connecting plate. The other end of each guide rod is connected to a bottle-clamping plate arranged parallel to the conveying direction of the conveying section. The bottle-clamping plate has a clamping plate corresponding to the filling needles along its length. By providing a bottle-clamping section with clamping plates corresponding to each filling needle, the bottle opening below the filling section is limited and fixed, improving filling accuracy.

[0014] Furthermore, the support base is provided with a longitudinally extending strip groove, and a locking screw that is tightened onto the conveying part is located within the strip groove. The locking screw and the strip groove work together to achieve vertical adjustment of the bottle-holding part, meeting the bottle-holding needs of bottle openings of different heights, thus broadening its applicability.

[0015] Furthermore, the material box includes a box body and a partition disposed inside the box body. The partition is provided with evenly spaced ventilation holes, which divide the box body into an upper chamber and a lower chamber that are interconnected, in order to filter out air bubbles generated during feeding.

[0016] Furthermore, the bottom of the box is a slope.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects:

[0018] (1) This utility model optimizes the structure of the filling needle nozzle. By setting a suction hood with an exhaust port, the bottle mouth is covered during filling. The corrosive gas volatilized during filling is collected in time to the waste gas treatment system through the exhaust port. Combined with the closed outer frame, the risk of corrosive gas diffusion is reduced, avoiding pollution to areas outside the equipment and parts that are not in direct contact with the material, and extending the service life of the whole machine.

[0019] (2) By setting up a main air intake pipe and an air inlet that connect the inner cavity of the outer frame, this utility model can draw clean air into the equipment and at the same time discharge and centrally treat the air containing slightly corrosive gases in a timely manner, thereby reducing the risk of corrosion inside the equipment and further extending the service life of the whole machine.

[0020] (3) By setting a second partition, this utility model forms a double-layer table with the first partition. Through the air intake hole, the air inside the equipment can be evenly drawn away, avoiding the phenomenon that the suction force in some areas is too large and the suction force in some areas is too small, thus ensuring that the gas inside the equipment can be effectively replaced.

[0021] (4) By setting up a receiving part, this utility model avoids the bottle containing corrosive liquid from tipping over and contaminating the equipment parts.

[0022] (5) This utility model protects the main power components by using anti-corrosion covers to prevent them from being corroded.

[0023] (6) This utility model fills the space between the corrosion protection cover and the power component with protective gas to form a slightly positive pressure state, thereby preventing corrosive gases from entering the interior and further improving the protective effect of the corrosion protection cover.

[0024] (7) This utility model uses the cooperation between the photoelectric accessory part and the baffle assembly to accurately stop the bottle conveyed by the conveying part below the filling part.

[0025] (8) The material box of this utility model can effectively filter air bubbles in the material box by setting a partition with vent holes, thereby improving filling accuracy.

[0026] (9) This utility model avoids material accumulation by setting the bottom of the material box as an inclined surface, thus preventing waste during cleaning. Attached Figure Description

Detailed Implementation

[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0036] (Example 1)

[0037] like Figures 1 to 5 The fully automatic anti-corrosion filling machine shown includes an outer frame section 1, a material bin section 2, a conveying section 3, a filling section 4, and a bottle clamping section 5. The outer frame section 1 has a closed door, placing the internal components in a relatively enclosed space. The material bin section 2 is mounted on top of the outer frame section 1 and stores corrosive liquid materials. The conveying section 3 extends horizontally through the outer frame section 1, transporting empty bottles to be filled into the outer frame section 1 and conveying filled bottles out of the outer frame section 1. The filling section 4 has multiple sections located above the conveying section 3, connecting to the material bin section 2. The number of bottle clamping sections 5 is the same as that of the filling section 4, located on the side of the conveying section 3, corresponding one-to-one with the filling section 4, used to clamp the bottle necks of the conveyed bottles, cooperating with the filling section 4 to achieve automatic filling. The filling section 4 is equipped with multiple filling needles 4-1. Each filling needle 4-1 has a suction hood 4-2 at its discharge nozzle to cover the bottle mouth during filling. The suction hood 4-2 has an exhaust port 4-2-1 on its side wall. The exhaust port 4-2-1 is connected to an external exhaust gas treatment system through a pipe. Corrosive gases volatilized during filling are collected in a timely manner through the exhaust port 4-2-1 and sent to the exhaust gas treatment system. Combined with the enclosed outer frame, the risk of corrosive gas diffusion is reduced, avoiding pollution to areas outside the equipment and parts that are not in direct contact with the material, thus extending the service life of the entire machine.

[0038] Specifically, the material bin 2 includes a bin body and a partition disposed within the bin body. The partition has evenly spaced ventilation holes, dividing the bin body into an interconnected upper chamber and a lower chamber to filter air bubbles generated during feeding and improve filling accuracy. The bottom of the bin body is sloped to prevent material accumulation and waste during cleaning.

[0039] The inlet of the conveying unit 3 is equipped with a photoelectric accessory 6 for sensing the bottle body. Multiple blade-stopping assemblies 7, corresponding to the filling unit 4, are located along the length of the side. Through the cooperation of the photoelectric accessory 6 and the blade-stopping assemblies 7, the bottles conveyed by the conveying unit 3 are accurately positioned below the filling unit 4. Each blade-stopping assembly 7 is located on the side of the corresponding filling unit 4 near the inlet of the conveying unit, and includes a U-shaped mounting base 7-1 fixed to the side of the conveying unit 3. A blade-stopping cylinder 7-2 is mounted on the mounting base 7-1. A blade-stopping block 7-3 is connected to the piston rod of the blade-stopping cylinder 7-2, located within the U-shaped cavity of the mounting base 7-1. The distal end of the blade-stopping block 7-3 has a bevel for easy insertion between adjacent bottles.

[0040] The bottle clamping unit 5 includes a support base 5-1 located on the side of the conveying unit 3. The support base 5-1 has a longitudinally extending strip groove 5-1-1, within which a locking screw is tightened onto the conveying unit 3, allowing for adjustable height. A telescopic cylinder 5-2 is located at the top of the support base 5-1. A connecting plate 5-3 is vertically mounted at the piston rod end of the telescopic cylinder 5-2. Guide rods 5-4 are parallel to both ends of the connecting plate 5-3. The other end of each guide rod 5-4 is connected to a bottle clamping plate 5-5, which is parallel to the conveying direction of the conveying unit 3. The bottle clamping plate 5-5 has a clamping plate 5-6 along its length, corresponding to the filling needle, thereby limiting and fixing the bottle opening below the filling unit, improving filling accuracy. The entire bottle clamping unit 5 is adjustable in height to meet the bottle clamping needs of bottle openings of different heights, thus broadening its applicability.

[0041] Both the filling and bottle-carrying sections use cylinders as their power source. The cylinders are equipped with corrosion-resistant covers, such as the knife-stop cylinder 7-2 and the telescopic cylinder 5-2, to prevent corrosion from volatile corrosive gases. A protective cylinder fills the space between the corrosion-resistant cover and the cylinder, creating a slightly positive pressure sealed space to prevent corrosive gases from entering and further enhancing the protective effect of the corrosion-resistant cover. Furthermore, for components where corrosion-resistant covers are easily installed, such as the knife-stop block 7-3, they are also covered with external corrosion-resistant covers. All internal components of the equipment are made of corrosion-resistant materials whenever possible. For load-bearing structures or components that cannot be made of corrosion-resistant materials, a Teflon anti-corrosion coating is applied to the surface.

[0042] To reduce the risk of corrosion from volatile corrosive gases, this embodiment features a first partition 8 sealed at the bottom of the outer frame 1, with an air inlet 1-1 connected to the top. A main suction pipe 9, penetrating the first partition 8 and connecting to the inner cavity of the outer frame 1, is located below the first partition 8. The outlet of the main suction pipe 9 is connected to an external waste gas treatment system, thereby promptly expelling corrosive gases and drawing clean external air into the equipment for gas replacement. Furthermore, to avoid localized areas with high suction and localized areas with low suction, and to ensure effective gas replacement within the equipment, this embodiment features a second partition 10 sealed above the first partition 8. The surface of the second partition 10 has evenly distributed suction holes, forming a double-layer platform with the first partition 8. These suction holes allow for the even removal of air from the equipment's interior.

[0043] Considering that the bottle containing corrosive liquid may tip over and contaminate the components below during filling, this embodiment has a receiving part 11 fixedly installed at the lower part of the outer frame 1, located directly below the filling part 4. The receiving part 11 is also made of corrosion-resistant material to prevent corrosive liquid from contaminating the equipment components when it tipped over.

[0044] This invention optimizes the structure of the feeding nozzle of the filling needle 4-1 by setting a suction hood 4-2 with an exhaust port 4-2-1 to cover the bottle mouth during filling. The corrosive gases volatilized during filling are collected in time to the waste gas treatment system through the exhaust port 4-2-1. Combined with the enclosed outer frame 1, the risk of corrosive gas diffusion is reduced, avoiding pollution to areas outside the equipment and parts that are not in direct contact with the material, thus extending the service life of the entire machine. At the same time, a double-layer platform with suction function is added, combined with the air inlet, to realize real-time air replacement inside the outer frame 1, effectively solving the problem of a small amount of corrosive gas overflowing from the suction hood 4-2. In addition, the materials of the equipment parts are changed, and anti-corrosion protection is provided for parts whose materials cannot be changed, extending the service life of the equipment.

[0045] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
