Description

Technical Field

[0001] This utility model relates to the field of solid phase extraction column technology, and in particular to a semi-automatic packing device. Background Technology

[0002] Solid phase extraction columns (SPE columns) have a wide range of applications in chemical analysis, environmental monitoring, food safety testing, drug development, and many other fields. They play a crucial role in sample pretreatment, effectively separating, purifying, and enriching target compounds, thereby improving the accuracy and sensitivity of analytical detection.

[0003] In the manufacturing process of solid phase extraction columns, the column packing process is a crucial step. Traditionally, this process relies heavily on manual operation. However, manual column packing makes it difficult to ensure high consistency in each operation, resulting in significant quality variations between different batches of solid phase extraction columns, which affects the overall stability and reliability of the product. Therefore, this application provides a semi-automatic packing device to meet this requirement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a semi-automatic packing device to solve the problem that the use of manual operation in the column packing process of solid phase extraction columns leads to differences between different batches of solid phase extraction columns.

[0009] When the cylinder is in its first half-stage operation, it is configured to press the column tube tightly.

[0010] When the cylinder is in its second half of operation, it is configured to press the sieve plate into the column tube.

[0011] The filler assembly includes: a support column; and a spiral powder injector, disposed on one side of the support column and located above the second positioning fixture.

[0012] It also includes: a dust collection component, which is disposed on the spiral powder injection machine. The dust collection component includes: a dust collection hood, which is disposed at the feed inlet of the spiral powder injection machine. The dust collection hood is annular.

[0013] It also includes: a connecting tube, one end of which is connected to the dust collection cover; and several dust collection holes, which are located inside the dust collection cover.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects.

[0015] In the above scheme, by setting two loading components and using a cylinder to load the sieve plate, the force and position of the sieve plate can be controlled more precisely, ensuring the consistency of loading the bottom and top sieve plates each time.

[0022] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of this utility model. However, this is only for illustrative purposes and is not intended to limit this utility model to the specific structure, device and environment. According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0023] The semi-automatic filling device provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0024] like Figure 1 - Figure 4 As shown, an embodiment of this utility model provides a semi-automatic filling device, comprising: a filling assembly 1 for loading materials; a first loading assembly 2 disposed on one side of the filling assembly 1 for loading the bottom sieve plate; a second loading assembly 3 disposed on the other side of the filling assembly 1 for loading the top sieve plate; the first loading assembly 2 and the second loading assembly 3 are identical; a first positioning clamp 12 disposed on the first loading assembly 2; two ball-head plungers 13 disposed within the first positioning clamp 12; a column tube 11 inserted into the first positioning clamp 12; an electronic balance 9 disposed on one side of the filling assembly 1; and a second positioning clamp 8 disposed on the electronic balance 9.

[0025] By setting up the packing assembly 1, the first loading assembly 2, and the second loading assembly 3, the operator only needs to install and remove the column tube 11 and start different work processes of the equipment according to the prompts. This makes the operation process simple and convenient, reduces the complexity of manual operation, and can be adjusted according to actual needs. For example, the stroke, pressure, and other parameters of the cylinder 10 can be set within a certain range to adapt to the installation requirements of column tubes 11 and screen plates of different specifications and materials. By setting up two ball-head plungers 13, when the column tube 11 is inserted into the first positioning clamp 12, the ball-head plungers 13 can abut against the column tube 11 from the side, restricting the horizontal movement of the column tube 11 and ensuring that the column tube 11 is in the correct position when the bottom screen plate is installed. The same applies to the installation of the top screen plate.

[0026] The first loading assembly 2 includes: a mounting column 7, disposed on one side of the packing assembly 1; and a cylinder 10, disposed on top of the mounting column 7. By setting the mounting column 7, a channel is provided within it, and the output end of the cylinder 10 moves along the channel to load the screen plate or fix the column tube 11. It also possesses sufficient strength and stability to withstand various forces generated by the cylinder 10 during operation, including the thrust and pull forces during the extension and retraction of the cylinder 10, as well as the weight of the cylinder 10 itself.

[0027] A placement groove is provided at the bottom of the mounting post 7 for placing the first positioning fixture 12. The size of the placement groove is larger than that of the first positioning fixture 12. By providing a placement groove, a dedicated placement position is provided for the positioning fixture. The operator only needs to place the positioning fixture into the placement groove to achieve its initial positioning at the bottom of the mounting post 7.

[0028] When the cylinder 10 operates in its first half, it is configured to press the column tube 11 tightly. By extending the cylinder 10 and contacting the column tube 11, the column tube 11 is pressed tightly within the positioning mold, ensuring that the column tube 11 does not move in the horizontal or vertical directions.

[0029] During the latter half of cylinder 10's operation, it is designed to press the screen plate into the column tube 11. As cylinder 10 extends, and because the column tube 11 is stably pressed, the extension of cylinder 10 pushes the screen plate, allowing it to accurately enter the column tube 11 along a predetermined direction and position. This reduces deviations in the screen plate's installation position, improves the fit between the screen plate and the inner wall of the column tube 11, and simultaneously, because the column tube 11 is firmly fixed, the reaction force on the entire equipment is better dispersed and balanced, reducing vibration and shaking caused by uneven local stress.

[0030] The filling assembly 1 includes: a support column 4; and a spiral powder injector 6, which is located on one side of the support column 4 and above the second positioning fixture 8. The spiral powder injector 6 includes a material frame with a conical top to facilitate material entry. A spiral conveyor is installed inside the material frame, and a motor is installed on the spiral conveyor. The motor is electrically connected to an electronic balance 9. A discharge pipe is installed at the bottom of the material frame. The motor drives the spiral conveyor, such as a spiral conveyor rod, to rotate, thereby moving the material along the spiral blades and discharging it into the column tube 11 through the discharge pipe. Simultaneously, the electronic balance 9 weighs the material in the column tube 11 in real time, and the motor rotation is controlled based on the feedback from the electronic balance 9.

[0031] It also includes a dust collection component 5, which is installed on the spiral powder injection machine 6. The dust collection component 5 includes a dust collection hood 51, which is installed at the feed inlet of the spiral powder injection machine 6 and is ring-shaped. By setting the dust collection hood 51, the ring-shaped design can form a relatively closed space around the feed inlet of the spiral powder injection machine 6, capturing dust generated during the feeding process from all directions.

[0032] It also includes: a connecting pipe 53, one end of which is connected to the dust collection hood 51; and several dust collection holes 52, which are disposed inside the dust collection hood 51. By setting the connecting pipe 53, it can be connected to an external vacuuming device. When not vacuuming, the connecting pipe 53 is in a sealed state and is only opened when working. By setting the dust collection holes 52, a uniform negative pressure distribution is formed in the area covered by the dust collection hood 51. When the external vacuuming device is started, a negative pressure is generated inside the dust collection hood 51 through the connecting pipe 53. Air will enter the dust collection hood 51 from the dust collection holes 52 and be sucked into the connecting pipe 53 along with the dust.

[0033] The technical solution provided by this utility model involves placing a bottom sieve plate inside a column tube 11, inserting the column tube 11 into a first positioning clamp 12, and then placing the first positioning clamp 12 into a placement slot. An external controller is used to activate a cylinder 10, which extends to press the column tube 11 firmly into the first positioning clamp 12, then presses the bottom sieve plate into the column tube 11. The column tube 11 is then removed and placed into a second positioning clamp 8, and filled using a spiral powder injector 6. During the filling process, an electronic balance 9 weighs the material inside the column tube 11 in real time. Based on the weighing feedback from the electronic balance 9, the rotation of the motor inside the spiral powder injector 6 is precisely controlled to ensure that the specified weight of filler is loaded into the column tube 11. Simultaneously, during the filling process, an external device is connected to a connecting pipe 53, and dust is absorbed through a dust suction hole 52. The column tube 11 is then removed and placed into a positioning clamp on a second loading assembly 3. The cylinder 10 in the second loading assembly 3 operates, and the above operation is repeated to press the top sieve plate into the column tube 11.

To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
