A semi-automatic filling device for konjac tissue culture medium

Abstract

This utility model discloses a semi-automatic filling device for konjac tissue culture medium, including a base plate, a vertically fixed mounting plate, a high-mounted hopper, and a filling system. The filling system consists of a connecting pipe, a vertical pipe, and a sliding rod assembly. The sliding rod assembly includes a coaxially fitted circular pipe and a slidable circular rod. The side wall of the circular pipe has vertical grooves and multiple equidistant horizontal grooves. An L-shaped bent rod welded to the top of the circular rod achieves five-level flow rate adjustment through its bending part positioning between the groove and the horizontal groove. When the bent rod is engaged at the bottom of the groove, the lower end of the circular rod presses against the annular step inside the vertical pipe to form a hard seal. When the bent rod is engaged in horizontal grooves of different heights, the lower end of the circular rod corresponds to the opening of the connecting port, precisely controlling the flow rate of viscous culture medium. The mounting plate has multiple through holes connected in parallel to multiple systems. Combined with gravity feeding from the hopper, it achieves multi-channel synchronous filling, improving efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of filling device technology, specifically relating to a semi-automatic filling device for konjac tissue culture medium. Background Technology

[0002] In konjac tissue culture, the amount of culture medium dispensed directly affects the seedling survival rate. Traditional filling methods, which rely on manual pouring or simple valve control, have significant drawbacks:

[0003] (1) Insufficient precision: Manual operation makes it difficult to ensure that the volume of each culture medium bottle is consistent, resulting in uneven nutrition of tissue culture seedlings;

[0004] (2) Low efficiency: The single-channel filling speed is slow, and large-scale production requires the cooperation of many people, resulting in high labor costs;

[0005] (3) Uncontrollable flow rate: Existing valve-type devices can only achieve on and off control, which cannot meet the gradient flow rate regulation requirements of konjac culture medium;

[0006] (4) Sealing hazards: Frequent operation can easily lead to wear of the seals, and the culture medium can easily leak and contaminate the equipment. Traditional equipment is difficult to disassemble and clean.

[0007] Therefore, there is an urgent need for a semi-automatic filling device that combines flow grading control, rapid sealing, and multi-channel synchronous operation. Summary of the Invention

[0008] To overcome the problems in the background art, this utility model provides a semi-automatic filling device for konjac tissue culture medium.

[0009] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0010] A semi-automatic filling device for konjac tissue culture medium includes a base plate, a mounting plate, a hopper, and a filling system. The mounting plate is vertically fixed to the middle of the base plate. The hopper is supported by two support rods on the rear side of the mounting plate, with the bottom surface of the hopper higher than the top surface of the mounting plate. The filling system is mounted on the mounting plate and includes:

[0011] The connecting pipe passes through the through hole at the top of the mounting plate, with one end connected to the bottom of the hopper.

[0012] A vertical pipe, connected vertically to the other end of the connecting pipe;

[0013] The slide bar assembly, located at the top of the vertical tube, includes:

[0014] A round tube is coaxially fitted and fixed to the top of a vertical tube, with a top cover provided at the top;

[0015] A round rod that can be slidably inserted into the inner cavity of a round tube and a vertical tube;

[0016] L-shaped bent rod, vertically welded to the top of the round rod;

[0017] in:

[0018] The sidewall of the circular tube is provided with a vertical sliding groove and a plurality of horizontally extending equidistant grooves, which are distributed on the side of the sliding groove.

[0019] The diameter of the bent rod matches the width of the slide groove and the transverse groove, and its bent part can slide along the slide groove or be inserted into the transverse groove.

[0020] Furthermore, the position of the bent rod enables gear control:

[0021] When the bent part of the rod is placed at the bottom of the groove, the lower end of the round rod seals the connection port between the connecting pipe and the vertical pipe.

[0022] When the bent part of the rod is inserted into the horizontal groove at different heights, the lower end of the round rod is located at different positions below the connecting port, thus adjusting the culture medium flow rate;

[0023] When the bent part of the rod is placed in the highest horizontal groove, the lower end of the round rod is completely above the connection port, allowing the culture medium to flow freely.

[0024] Furthermore, the mounting plate has multiple horizontal through holes on its upper part, each through hole passing through a set of connecting pipes to form multiple filling systems connected in parallel.

[0025] Furthermore, the lower part of the inner cavity of the vertical tube is provided with an annular step. When the bent rod is placed at the bottom of the slide groove, the lower end of the round rod abuts against the step to achieve sealing and limiting.

[0026] Furthermore, a limiting ring is provided on the upper outer side of the vertical tube, and the bottom of the round tube abuts against the limiting ring after being fitted to achieve axial fixation.

[0027] Furthermore, it also includes a sleeve and a hose; the lower end of the vertical pipe has an external thread on its outer wall, and the upper end of the sleeve has a matching internal thread on its inner wall, and the two are threaded together; the hose is sleeved and fixed to the lower end of the sleeve.

[0028] The beneficial effects of this utility model are:

[0029] This utility model has the following outstanding advantages compared with the prior art:

[0030] (1) Precise and controllable flow rate: Through the multi-position horizontal groove design of the slide bar assembly, multi-level flow rate adjustment can be achieved to meet the culture medium increment requirements of different growth stages of konjac tissue culture; when the bent rod is inserted into the highest horizontal groove, the round rod is completely disengaged from the connection port to achieve full flow rate filling.

[0031] (2) Zero leakage seal: The lower end of the round rod fits and seals against the plane of the annular step to prevent leakage of viscous culture medium; the self-weight locking mechanism of the bent rod sliding into the bottom of the vertical groove avoids accidental valve opening caused by operational vibration.

[0032] (3) Multi-channel high-efficiency operation: The parallel multi-hole design on the mounting plate supports simultaneous filling of multiple channels, greatly improving efficiency; the silo is set up at a high position, and the energy consumption is reduced by using the gravity flow principle.

[0033] (4) Easy maintenance: The quick-release threaded structure of the sleeve and the vertical pipe enables the rapid replacement of the hose, solving the problem of time-consuming replacement of traditional adhesive hoses; the round pipe is axially fixed by the limiting ring, without the need for bolt tightening, making it easy to disassemble and clean.

Detailed Implementation

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0043] Example 1: Six-channel high-precision filling system

[0044] (1) Structural configuration

[0045] This embodiment provides a standardized six-channel filling device, see reference. Figures 1-3 As shown, it includes:

[0046] Support structure: The rectangular base plate 1 is made of 304 stainless steel, with the mounting plate 2 vertically welded to its center. The mounting plate 2 has six horizontal through holes at the top, with a spacing of more than 80mm. The hopper 3 has a volume of more than 50L and is supported at an angle on the back of the mounting plate 2 by two support rods 31, forming a gravity drop between the bottom surface of the hopper 3 and the top surface of the mounting plate 2.

[0047] Filling system: Six sets of parallel systems pass through the through holes of the mounting plate 2. One end of the connecting pipe 4 is flanged to the bottom outlet of the hopper 3, and the other end is vertically welded to the vertical pipe 5. The lower part of the inner cavity of the vertical pipe 5 is machined into an annular step 51, and the upper part is welded with a limiting ring 52.

[0048] Flow control mechanism: The round tube 61 of the slide rod assembly 6 is sleeved on the top of the vertical tube 5, and the bottom abuts against the limiting ring 52. A vertical slide groove 611 and five equidistant horizontal grooves 612 are laser-cut on the side wall of the round tube 61. The round rod 62 is inserted into the inner cavity of the round tube 61, and an L-shaped bent rod 64 is welded to the top, with its bent part fitting with the slide groove 611 with clearance.

[0049] Discharge module: The lower end of the vertical pipe 5 is machined with an M20 external thread, and the sleeve 7 is screwed on. The hose 8 is fixed to the lower end of the sleeve 7 by a clamp.

[0050] (2) Work process and problem solving

[0051] See sealed condition. Figure 5 As shown: Press the bent rod 64 down to the bottom of the slide groove 611, and the lower end of the round rod 62 presses against the annular step 51 to form a metal hard seal, completely blocking the flow of culture medium and solving the leakage problem of traditional valves.

[0052] Flow regulation: See Figure 4As shown, lift the bent rod 64 to the different transverse grooves 612 and insert it into the first transverse groove: the lower end of the round rod 62 is 5mm away from the connecting opening, forming a narrow flow, which is suitable for micro-filling during the seedling start-up period; insert it into the third transverse groove: the round rod 62 is raised to the middle of the opening, the flow increases, and it meets the needs of the growth period; insert it into the highest transverse groove: the round rod 62 is completely detached from the opening, the full flow is the largest, and the filling speed is the fastest.

[0053] Multi-channel synchronization: Multiple systems can be adjusted independently, allowing operators to control the differentiated processes of six bottles simultaneously, significantly improving efficiency compared to single-channel systems.

[0054] (3) Technical effects

[0055] Precise flow control with multiple flow levels adapts to viscosity changes at various stages of konjac tissue culture; metal hard seal achieves zero leakage; multi-channel parallel design significantly accelerates bottling speed while reducing labor costs.

[0056] Example 2: Twelve-channel anti-drip production line

[0057] (1) Structural innovation

[0058] Based on Example 1, a production line-level upgrade and expansion were carried out.

[0059] Expanded channel: Mounting plate 2 is widened to 1200mm, twelve horizontal through holes are opened, connecting pipe 4 is increased to twelve sets, and hopper 3 is expanded to 100L.

[0060] Anti-drip design: A conical sealing plug is added to the inner cavity of the vertical pipe 5. When the round rod 62 is lifted, its lower conical surface forms a line seal with the annular step 51 to prevent the culture medium from dripping off the wall when the pump is stopped.

[0061] Quick-release optimization: A quick-connect connector is added between the sleeve 7 and the hose 8, and quick disassembly can be achieved by pressing the buckle.

[0062] (2) Work process and problem solving

[0063] Anti-drip mechanism: When the filling is finished and the bending rod 64 is pressed down, the conical surface of the round rod 62 first contacts the annular step 51, squeezing out the residual culture medium, and finally the plane seal completely intercepts the flow, solving the common dripping pollution problem in the industry.

[0064] Large-scale collaboration: Twelve systems are controlled in three zones, suitable for simultaneous filling of three different sizes of culture bottles.

[0065] Emergency maintenance: When a hose 8 becomes blocked, there is no need to stop the machine. Simply unscrew the sleeve 7 and replace it with a spare hose 8.

[0066] (3) Technical effects

[0067] The production line's daily processing capacity has increased by 2 times, and the modular design has shortened the time for troubleshooting. Zoned control enables flexible production, and switching product specifications requires no equipment adjustment.

[0068] Example 3: Portable Single-Channel Filler

[0069] (1) Lightweight design

[0070] For small-scale laboratory scenarios, see Figure 4 Simplified structure.

[0071] Simplified structure: Base plate 1 is reduced to 200×150mm, mounting plate 2 is reduced to 400mm in height, and only a single through hole is retained. The hopper 3 is replaced with a 5L portable container, and the support rod 31 adopts a foldable hinge structure.

[0072] Integrated slide bar: The round tube 61 and the vertical tube 5 are machined into a single piece to reduce welding points, and the horizontal groove 612 is reduced to three levels.

[0073] Direct connection with flexible hose: the sleeve 7 is removed, and the flexible hose 8 directly covers the threaded section at the lower end of the vertical pipe 5 through heat shrink tubing.

[0074] (2) Work process and problem solving

[0075] Quick start and stop: One-handed operation by holding the curved rod 64: push the thumb down to the bottom of the slide groove 611 to seal; lift it up to lock into the horizontal groove 612 to achieve one-handed flow regulation, solving the pain point of two-handed operation in traditional devices.

[0076] Viscosity adaptation: For the high viscosity characteristics of konjac culture medium, the three horizontal grooves of 612 correspond to:

[0077] Low position is suitable for high viscosity culture media: low flow rate prevents splashing;

[0078] High-volume solutions are suitable for low-viscosity nutrient solutions: high flow rate increases speed.

[0079] Mobile operation: It can be carried to the laminar flow hood for direct filling, avoiding culture medium transfer and contamination.

[0080] (3) Technical effects

[0081] Improved operational efficiency, reduced number of parts, and lower manufacturing costs; suitable for mobile operations in sterile environments, reducing the risk of contamination.
