Description

Technical Field

[0001] The utility model belongs to the technical field of microbial cultivation, and in particular relates to a feeding component with a preheating function. Background Art

[0003] In the production of large quantities of plate culture media, it is completed by the assembly line; the culture dishes are placed in the storage box, and the assembly line automatically pushes multiple culture dishes to the conveyor belt, which carries the culture dishes to the filling station to complete the filling, and then proceeds to the next step. On the current plate culture medium production line, the storage mechanism used to store the culture dishes often lacks measures to preheat the culture dishes; so when the room temperature culture dishes arrive at the filling station, the higher temperature agar is poured into the culture dishes. The temperature difference between the two is large, and the hot air on the agar contacts the lower temperature of the culture dish wall to produce condensation water; when the agar cools and solidifies, condensation water will accumulate on the culture medium, affecting the quality of the culture medium.

DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0055] Example 1

[0056] A feeding assembly with a preheating function, comprising: a material storage box 1, a box door 2, a bottom box 4, and a heating assembly;

[0057] like Figure 1 As shown, the storage box 1 is set as a rectangular box structure, and a dish slot 3 structure for placing the culture dish is opened in the storage box 1; the dish slot 3 is vertically opened as a hollow structure, and from a top view, the dish slot 3 is an "n"-shaped structure; the flat plate culture dish itself is a cylindrical structure, and is circular from a top view. Figure 2 As shown, after the culture dish 9 is placed in the dish groove 3, a part of the side edge of the culture dish 9 can be completely attached to the inner wall of the arc segment of the dish groove 3;

[0058] like Figure 2 As shown, four parallel dish slots 3 are provided in the storage box 1, and unused new culture dishes 9 are stacked and uniformly placed in the dish slots 3; this ensures that the culture dishes 9 are neatly placed and increases the number of culture dishes 9 that can be placed;

[0059] The upper end and one side of the dish groove 3 are open structures. The opening structure at the upper end is opened on the upper surface of the material storage box 1; the opening structure at one side of the dish groove 3 is opened on the front side of the material storage box 1.

[0060] A door 2 is provided at each side of the front side of the storage box 1 through a hinged joint. When the two doors 2 are closed, the opening of the dish slot 3 on the front side of the storage box 1 can be closed; the culture dish 9 is placed in the dish slot 3, and the door 2 is closed. At this time, the side wall of the dish slot 3 can contact the door 2, and the door 2 closes the opening of the side of the dish slot 3, so that the culture dish 9 will not move in the dish slot 3. Figure 1As shown, a handle 201 is provided on the door 2; a bolt rod 202 is hinged at the upper position of one door 2; a latch 203 is provided at the upper position of the other door 2; the door 2 can be locked by rotating the bolt rod 202 and placing it in the latch 203.

[0061] A bottom box 4 is provided below the storage box 1. Figure 3 As shown, four "n"-shaped notches are provided on the upper surface of the bottom box 4; each notch corresponds to a dish slot 3 in the storage box 1; the dish slot 3 is located above the notch, and the area encircled by the arc segment on the dish slot 3 and the arc segment on the notch is exactly the same size as the culture dish 9;

[0062] A push plate 5 is movably arranged inside the bottom box 4 and below the notch groove, and the push plate 5 is as close to the bottom of the notch groove as possible, but does not contact the notch groove; at least two sets of push components are arranged below the push plate 5, and the push components can be used to drive the push plate to move forward and backward;

[0063] like Figure 4 As shown, the above-mentioned pushing assembly includes: a motor 404, a conductive roller 402, a gear 403 and a rack 501; one end of the conductive roller 402 penetrates into the bottom box 4 from one side of the bottom box 4, and is rotatably arranged on the inner wall of the other side of the bottom box 4; the other end of the conductive roller 402 is located outside the bottom box 4; the motor 404 is arranged on the other end of the conductive roller 402; two gears 403 are arranged on the conductive roller 402 located in the bottom box 4; a rack 501 is arranged at a position on the lower surface of the push plate 5 facing the gear 403; the gear 403 is meshed with the rack 501 arranged below the push plate 5; the motor 404 rotates to drive the conductive roller 402 to rotate, and the conductive roller 402 drives the gear 403 thereon to rotate, and the meshing between the gear 403 and the rack 501 can drive the push plate 5 to move forward and backward;

[0064] The culture dishes 9 are stacked and placed in the dish slot 3, and the bottom culture dish 9 is placed on the push plate 5; a dish outlet 301 is opened on the arc-shaped side wall below the dish slot 3, and the dish outlet 301 extends all the way to the back of the storage box 1; the height of the dish outlet 301 is slightly greater than the thickness of the culture dish 9, so that the culture dish 9 can be moved out of the storage box 1 from the dish outlet 301; and only the culture dish 9 at the bottom can pass through the dish outlet 301.

[0065] The push plate 5 moves backward, driving the culture dish 9 at the bottom to move, and the culture dish 9 is moved out of the storage box 1 to the next workstation for opening the cover; after the culture dish 9 is moved out, the push plate 5 moves in the opposite direction to return to its original position. During the reverse movement of the push plate 5, the stacked culture dishes 9 will not shift as a whole due to the restriction of the box door 2.

[0066] No matter the push plate 5 moves forward or backward, the length of the notch groove on the bottom box 4 and the length of the push plate 5 are set so that there is always a push plate 5 under the notch groove to support it, and the push plate 5 will not move away from the notch groove, causing a vacancy under the notch groove.

[0067] When the bottommost culture dish 9 is removed, the second-to-last culture dish 9 becomes the bottommost culture dish 9 and automatically falls onto the push plate 5 , waiting to be pushed to the next station by the push plate 5 next time.

[0068] The storage box 1 is made of stainless steel as a whole, and the interior of the storage box 1 is set to a hollow structure. An electric heating tube is set inside the storage box 1, and the electric heating tube is connected to a wire; the wire is led out of the storage box 1 and is located outside the storage box 1. The electric heating tube is heated by the wire to increase the temperature inside the storage box 1, and the temperature is transferred from the surface of the storage box 1 to the culture dish 9 in the dish slot 3, so that the surface of the culture dish 9 is preheated and heated; in this way, when the preheated culture dish 9 arrives at the filling station, the agar with a higher temperature is filled into the culture dish 9, which can reduce the temperature difference between the culture dish 9 and the agar, and minimize the situation where the hot air of the agar forms too much condensed water in the culture dish 9 due to the large temperature difference.

[0069] The electric heating tube and the wire constitute a heating assembly.

[0070] Example 2

[0071] Based on Example 1, in Example 1, the heating component adopts an electric heating tube arranged in a hollow structure in the storage box 1; although the electric heating tube has a high efficiency of heating effect; however, the electric heating tube is located in a closed space, which may pose a safety hazard.

[0072] like Figure 5 As shown, this embodiment uses a water bath to transfer the temperature to the dish slot 3 on the storage box 1, thereby preheating the culture dish in the dish slot;

[0073] Similarly, the interior of the storage box 1 is set to a hollow structure; a water inlet pipe 6 is set on the side wall of one side of the storage box 1, and a water outlet pipe 7 is set on the side wall of the other side; a water pump 8 is set on both the water inlet pipe 6 and the water outlet pipe 7. The water pump 8 pumps hot water into the storage box 1 through the water inlet pipe 6 and fills the space in the storage box 1; the temperature of the hot water is transmitted to the dish tank 3 through the stainless steel wall of the storage box 1 to preheat the culture dish 9 in the dish tank 3; when the temperature of the hot water in the storage box 1 decreases and is insufficient to continue preheating the culture dish 9, the water pump 8 on the water outlet pipe 7 is turned on to discharge the water in the storage box 1; and new hot water is added.

[0074] Example 3

[0075] Based on Example 2, in Example 2, hot water is poured into the storage box 1, and the temperature of the hot water will decrease as the heat diffuses. When the temperature of the hot water drops to a level that is insufficient to preheat the culture dish 9, the low-temperature water needs to be discharged and new hot water needs to be introduced. However, in Example 2, it is impossible to accurately determine whether the water in the storage box 1 still has the function of preheating the culture dish 9. This may cause the water temperature in the storage box 1 to be too low and unable to preheat the culture dish 9; or the temperature may still be high and the water needs to be replaced.

[0076] Therefore, in this embodiment, a temperature sensor is set in the storage box 1, and the temperature sensor is used to monitor the temperature of the water in the storage box 1 in real time; the temperature sensor is communicatively connected to the microprocessor, and the monitored temperature data will be fed into the microprocessor; the temperature threshold is preset in the microprocessor; the microprocessor is communicatively connected to the water inlet pipe 6 and the water pump 8 on the water outlet pipe 7.

[0077] The temperature sensor monitors the temperature of the water in the storage box 1, and the data is fed into the microprocessor; when the temperature sensor detects that the water temperature in the storage box 1 has dropped below the threshold and cannot diffuse enough heat to preheat the culture dish 9, the microprocessor sends a control instruction to the water pump 8 on the outlet pipe 7, so that the outlet pipe 7 starts to drain water outward; at the same time, the water pump 8 on the inlet pipe 6 is started to add hot water to the storage box 1; when enough hot water is added to the storage box 1 to continue preheating the culture dish 9, the microprocessor controls the water pump 8 to stop discharging old water and adding new water.

[0078] As a preferred real-time method, a timer switch can also be set on the water pump 8. The microprocessor controls the timer switch to control the start time of the water pump 8 on the water inlet pipe 6 and the water outlet pipe 7. The water can be circulated within a period of time to ensure that a sufficient amount of new hot water can be added and that there is enough heat to diffuse.

[0079] By automatically monitoring and adjusting the temperature of the water bath, the water temperature in the storage box 1 can always be maintained at a temperature sufficient to preheat the culture dish 9, thereby preventing the water temperature from being too low, resulting in insufficient preheating temperature of the culture dish 9.

[0080] Example 4

[0081] Based on Example 1, in Example 1, the culture dishes 9 are stacked and placed in the dish slot 3, and the bottom culture dish 9 is in direct contact with the surface of the push plate 5; the heat emitted from the storage box 1 is mostly concentrated on the side walls of the culture dishes 9 for preheating the culture dishes 9; since the bottom of the culture dishes 9 are stacked, the preheating temperature rises slowly.

[0082] Therefore, in this embodiment, an interlayer is provided inside the push plate 5, an electric heating rod is provided inside the interlayer, and the wire of the electric heating rod is led out of the push plate 5. The electric heating rod is used to heat up the push plate 5, so that the heat is diffused to the surface of the push plate 5; thus, after the bottom of the bottom culture dish 9 contacts the surface of the push plate 5, it can also be preheated quickly; and the preheating of the entire surface of the culture dish 9 can be made more uniform.

[0083] In addition, in Example 1, the four stacks of culture dishes 9 are equivalent to being placed on the push plate 5 and supported by the push plate 5; in order to make the push plate 5 more stable when moving, as shown in FIG. Figure 4 As shown, slide grooves 4011 are opened on the side walls of the bottom box 4; the two sides of the push plate 5 are movably placed in the slide grooves 4011; thus, the slide grooves 4011 are equivalent to providing a track for the movement of the push plate 5, so that the push plate 5 moves under the limit of the track, which can make the movement of the push plate 5 more stable.
