Description

Technical Field

[0001] This utility model belongs to the field of filter absorber technology, and specifically relates to a tooling for filling purification materials in a cylindrical filter absorber. Background Technology

[0002] The filter absorber is a core protective component in a filtration and ventilation system, playing a crucial role, especially in combating chemical pollution. Its production process involves the filling of purification materials, and the accuracy of this step directly determines the product's purification efficiency and protective performance. Currently, the common industrial filling process consists of two parts: loading and vibration, and replenishment and sealing. While loading and vibration have relatively mature quantitative control technology, effectively improving filling density and uniformity through precise settings of parameters such as air pressure, amplitude, and frequency, the replenishment and sealing process still relies on manual operation, which has the following main drawbacks:

[0003] 1. Human error is difficult to avoid

[0004] During the replenishment and sealing process, operators may make inaccurate judgments due to visual biases, leading to inaccurate filling of the purification material, or even localized accumulation or gaps. This defect directly affects the consistency of the purification material filling and may result in unstable protective performance; moreover, the filling height also relies on manual control, making it impossible to accurately guarantee the consistency of the product structure's molding dimensions.

[0005] 2. Poor compatibility between different models

[0006] Existing process equipment is difficult to adapt to filter absorbers of different specifications (such as differences in diameter or height), requiring frequent changes of tooling fixtures or adjustments of station parameters, which increases production preparation time and reduces tooling utilization.

[0007] 3. High labor intensity and harsh operating environment

[0008] The process of filling and sealing the medicine requires long hours of manual work in a dusty environment, which can easily cause occupational health damage to workers. At the same time, due to the lack of auxiliary positioning tools, it is necessary to repeatedly align the filling holes and confirm the sealing height during the operation, which consumes a lot of manpower and has low work efficiency. Utility Model Content

[0009] The purpose of this invention is to provide a tooling for filling purification materials in a cylindrical filter absorber, which solves the unavoidable operational errors caused by relying entirely on manual operation, and improves the product consistency of the filter absorber to a certain extent.

[0010] This utility model is achieved using the following technical solution:

[0011] A cylindrical filter absorber purification material filling fixture includes a positioning rod and a lever assembly. The positioning rod is vertically fixed on a base. The positioning plate is provided with a track groove, a guide groove, and a limiting groove. The track groove is arranged along the axial direction of the positioning rod, and the guide groove is arranged along the circumferential direction of the positioning rod. The guide groove communicates with the track groove. A limiting groove is provided below the guide groove and communicates with the guide groove. The lever assembly is limited by the limiting groove. A turntable structure is rotatably connected to the base.

[0012] In application, the lever assembly can be quickly fixed by the track groove, i.e. the limiting groove, on the positioning rod. The lever assembly is made of wear-resistant material and is adjusted in conjunction with the positioning rod, relying on gravity guidance to achieve the removal and control of excess purification material.

[0013] Preferably, the positioning rod is provided with a scale. This design gives the positioning rod its own height measurement function.

[0014] A further preferred embodiment includes a hexagonal nut, wherein the bottom of the positioning rod is threaded, and the base is provided with a threaded hole, and the positioning rod is mounted on the base by the hexagonal nut. In this way, the positioning rod is fixed to the base by the hexagonal nut, which serves to prevent loosening.

[0015] Further preferably, the turntable structure is mounted on the base via bearings. The bearings enable flexible rotation of the turntable structure and are used to support and fix various types of filter absorbers. The turntable structure can be made of metal or composite materials to accommodate filter absorbers of different weights. Preferably, the turntable structure can be driven to rotate by a motor.

[0016] More preferably, the base is a square plate with a boss, the turntable structure is rotatably connected to the boss, and the base is provided with through holes for fixing. The base provides overall stability and is compatible with different production line installation interfaces. The base is fixed to the work platform by bolts engaging with the through holes.

[0017] More preferably, the center of the turntable structure coincides with the center of the boss.

[0018] More preferably, the paddle assembly includes a paddle portion, and after the paddle assembly is installed, the length of the paddle portion reaches the center of the base.

[0019] In a further preferred embodiment, one end of the paddle assembly has a through short tube, and a protrusion is provided inside the short tube. The protrusion can slide along the track groove. The short tube is fitted onto the positioning rod and slides along the track groove to adjust the height of the paddle assembly. The rotation of the paddle assembly drives the protrusion into the guide groove. The continued rotation of the paddle assembly causes the protrusion to fall into the limiting groove, thereby limiting the paddle assembly. In application, the short tube is fitted onto the positioning rod, and the protrusion inside the short tube slides in the track groove. After the paddle assembly slides to the corresponding height, the paddle assembly is manually rotated. This causes the protrusion inside the short tube to be rotated into the guide groove. As the paddle assembly continues to rotate, the protrusion falls into the limiting groove due to gravity.

[0020] Preferably, there are multiple guide grooves and limiting grooves, each guide groove having a different height on the positioning rod. In actual use, multiple guide grooves and limiting grooves at different heights can be set on the positioning rod according to actual needs, enhancing the adaptability of this tooling.

[0021] More preferably, the paddle portion of the paddle assembly is a lever, which can be a straight lever or a lever with an arc or a slope. Depending on the requirements of the loading, a straight lever can be used, resulting in a flat surface after loading; a lever with an arc or a slope can be used, resulting in a curved or sloping surface after loading.

[0022] This utility model's purification material filling fixture has a simple overall structure and good processability. It can be used for replenishing and sealing the chemical in various filter absorbers. While improving the consistency of product quality, it reduces the labor intensity of operators and improves production efficiency.

[0023] The core objective of this invention is to solve the error problem caused by manual operation, and to achieve the following two breakthroughs:

[0024] 1. Achieve semi-automated quantitative control of the drug application and sealing process;

[0025] 2. Ensure that the dimensions of the filter absorber are consistent after packaging, while also being suitable for multiple product models, thereby improving work efficiency and safety.

[0026] Compared with existing filter absorber purification material filling processes, the biggest advantage of this invention is that it achieves quantitative control of the replenishment, ensuring the amount of medicine added to the filter absorber according to the filling process requirements, avoiding human error, and improving product consistency to a certain extent. Furthermore, the height of the tooling's adjustable levers allows it to be applied to the filling of purification materials for various types of filter absorbers. This tooling also reduces the labor intensity of operators and improves work efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0038] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0039] A cylindrical filter absorber purification material filling fixture includes a positioning rod 1 and a paddle assembly 2. The positioning rod 1 is vertically fixed on a base 4. The positioning plate is provided with a track groove 11, a guide groove 12 and a limiting groove 13. The track groove 11 is arranged along the axial direction of the positioning rod 1, and the guide groove 12 is arranged along the circumferential direction of the positioning rod 1. The guide groove 12 communicates with the track groove 11. A limiting groove 13 is provided below the guide groove 12 and communicates with the guide groove 12. The paddle assembly 2 is installed with the limiting groove 13. A turntable structure 3 is rotatably connected to the base 4. The positioning rod 1 is provided with a scale.

[0040] It also includes a hexagonal nut, the bottom of the positioning rod 1 is threaded, the base 4 is threaded, the bottom thread of the positioning rod 1 is screwed into the threaded hole on the base 4 and then the hexagonal nut is installed, and the turntable structure 3 is mounted on the base 4 through a bearing.

[0041] The base 4 is a square plate with a boss. The turntable structure 3 is rotatably connected to the boss. The base 4 is provided with a through hole. The center of the turntable structure 3 coincides with the center of the boss.

[0042] After installation, the length of the paddle assembly 2 reaches the center of the base 4. One end of the paddle assembly 2 is provided with a through short tube 21, and a protrusion 22 is provided inside the short tube. The protrusion 22 can slide along the track groove 11. The short tube 21 is sleeved on the positioning rod 1 and slides along the track groove 11 to realize the height adjustment of the paddle assembly 2. The paddle assembly 2 rotates and drives the protrusion 22 into the guide groove 12. The paddle assembly 2 continues to rotate and causes the protrusion 22 to fall into the limiting groove 13, thereby realizing the limiting of the paddle assembly 2.

[0043] The working principle is as follows:

[0044] It mainly consists of a positioning rod 1, a paddle assembly 2, a turntable structure 3, and a base 4, with each component connected by fasteners. The paddle height is adjustable. After replenishing the filter absorber, it is placed on the turntable. Rotating the turntable structure 3 allows for further control of the amount of purification material filled, and ensures the forming dimensions of the filter absorber after subsequent sealing. This solves the unavoidable operational errors caused by relying entirely on manual operation, and improves the product consistency of the filter absorber to a certain extent.

[0045] The positioning rod 1 is fixed to the base 4 with a hexagonal nut, and the paddle is limited by the protrusion 22 on the positioning rod 1. The turntable structure 3 is connected to the base 4 through a bearing. First, place the workpiece on a horizontal surface. According to the process, adjust the paddle assembly 2 to the specified height by rotating it. Then, after the filter absorber has completed the filling and vibration processes, place it on the turntable structure 3 after replenishing the drug. Rotate the turntable structure 3, and the paddle part 23 will naturally adjust the replenished filter absorber to the specified height. Finally, seal the filter absorber with the drug.

[0046] The specific usage steps are as follows:

[0047] 1. Place the base 4 of the tooling on a horizontal workbench and secure it firmly;

[0048] 2. Adjust the height of the paddle assembly 2 to the preset standard position of the product by means of the track groove 11 on the positioning rod 1, then rotate the paddle assembly 2 to make the protrusion 22 enter the guide groove 12, and continue to rotate the paddle assembly 2 so that the protrusion 22 will fall into the limiting groove 13 on the positioning rod 1 due to gravity. In this way, the paddle assembly 2 is limited on the positioning rod 1. After the paddle assembly 2 is limited, the paddle part 23 is located directly above the turntable structure 3.

[0049] 3. Place the filter absorber, which has completed the drug loading and vibration process, stably on the turntable, and directly below the paddle part 23 of the paddle assembly 2;

[0050] 4. Add a measured amount of purification material to the designated area of ​​the filter absorber;

[0051] 5. The rotating turntable structure 3 enables the paddle assembly 2 to complete the trimming action, automatically adjust the filling height and remove excess purification material;

[0052] 6. Finally, perform precise packaging. Example 2

[0053] There are multiple guide grooves 12 and limiting grooves 13, and the height of each guide groove 12 on the positioning rod 1 is different. Example

[0054] The paddle assembly 2 includes a lever, which can be a straight lever or a lever with a curve or slope.

[0055] This invention enables further control over the amount of purification material filled, and ensures the forming size of the filter absorber after subsequent sealing. The height of the lever is adjustable, making it suitable for various filter absorbers. It has a simple structure and is easy to use.

[0056] Compared with existing filter absorber purification material filling processes, the advantages of this invention are as follows:

[0057] 1. Significant error control

[0058] The mechanical linkage enables precise setting of drug replenishment and sealing, ensuring product consistency; it avoids product specification differences caused by manual visual operation and improves the quality of mass production.

[0059] 2. Wide range of applications

[0060] The adjustable lever design combined with the standardized turntable structure allows the tooling to be adapted to multiple models of products with diameters of 30-50cm and lengths of 0.3-0.8m, saving costs by eliminating the need to purchase additional special equipment; moreover, the overall structure occupies little space (base size 4 ≤ 60×40×30cm), which facilitates flexible deployment on the production line.

[0061] 3. Improve work efficiency

[0062] The semi-automated mechanical operation reduces the time required for the traditional drug filling and sealing process from 5 minutes to about 2 minutes, and supports batch processing of multiple products in a single filling; at the same time, it reduces the direct dust exposure time of workers and meets the relevant occupational health and safety protection requirements.

[0063] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and all should be covered by the protection scope of the claims.
