Description

Technical Field

[0001] The utility model relates to the technical field of food detection assistance, in particular to a food additive detection test bench. Background Art

[0002] The food additive detection test bench is a table for carrying food additive detection equipment, but the devices in the prior art have certain disadvantages when used.

[0003] Although the above-mentioned device can be placed and limited, it is not convenient to adjust the height of the workbench, resulting in it being unable to adapt to staff members of different heights. It is also inconvenient to adjust the angle of the workbench when adjusting the height, resulting in some food residues being unable to be discharged from the workbench independently, increasing the workload of later staff members to clean the workbench. Utility Model Content

[0004] The purpose of the utility model is to provide a food additive detection test bench to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A food additive detection test bench comprises a base, the upper surface of the base is fixedly connected to a box body, the front surface of the box body is embedded with a mounting shaft rotatably connected, both ends of the mounting shaft are fixedly connected to connecting rods, the other end of the connecting rod is fixedly connected to a connecting half frame, the upper surface of the base is fixedly connected to a column, the upper end of the column is embedded with a movably connected limiting column, the upper end of the limiting column is fixedly connected to a placement frame, the upper surface of the placement frame is rotatably connected to a workbench, and the top of the base is fixedly connected to a bracket.

[0007] Furthermore, a through groove is formed on the side surface of the limiting column, a roller is rotatably connected inside the through groove, and the connecting half frame is in contact with the roller.

[0009] Furthermore, the outer surface of the connecting half frame is nested and connected with a sleeve half frame, and the upper surface of the sleeve half frame is threadedly connected with a locking knob.

[0010] Furthermore, a servo motor is fixedly connected to the side surface of the worktable, a double-headed screw is fixedly connected to the output end of the servo motor, the other end of the double-headed screw is rotatably connected to the worktable, a limiting rod is fixedly connected to the outer surface of the worktable, two scrapers are nested on the outer surface of the limiting rod, and the scrapers are threadedly connected to the double-headed screw.

[0011] Furthermore, a rubber pad is fixedly connected to the lower surface of the workbench, a mounting frame is fixedly connected to the lower surface of the workbench, a baffle is embedded and movably connected to the upper surface of the workbench, an insertion rod is fixedly connected to the lower surface of the baffle, a spring is nested on the outer surface of the insertion rod, the insertion rod passes through the baffle, both side surfaces of the workbench are fixedly connected to connecting shafts, the workbench is rotatably connected to a placement frame via the connecting shaft, and a gear is fixedly connected to the outer surface of the connecting shaft.

[0012] Furthermore, a collecting frame is fixedly connected to the rear surface of the bracket, an inclined plate is fixedly connected to the front surface of the collecting frame, a connecting pipe is embedded in the lower surface of the collecting frame, a negative pressure machine is fixedly connected to the end of the connecting pipe, and a rack is fixedly connected to the upper end of the bracket, and the rack and gear match.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] Start the stepper motor to rotate the worm. At this time, the worm drives the worm wheel to rotate, so that the installation shaft rotates, and drives the connecting rod to deflect around the installation shaft. The four connecting rods can be driven to deflect at the same time, and at the same time, a force is applied to the limit columns at the four corners of the placement frame, so that the rise or fall of the workbench is more stable;

[0015] The servo motor is started, and the output end of the servo motor drives the double-headed screw to rotate. When the double-headed screw rotates, the two scrapers move from the outside to the inside along the limit rod under the push of the thread, and scrape the upper surface of the workbench, so that the residue on the workbench enters the collection frame. In the normal state, the test tube rack or other equipment is clamped, and the equipment is limited by the workbench and the scraper. When the workbench rises, the gear and the rack contact, so that the gear is forced to drive the workbench to flip backward. The flipped workbench is equipped with a scraper, which is convenient for part of the residue to fall directly into the collection frame under the action of gravity, thereby reducing the pressure of later cleaning. The baffle plate and the inclined plate are in conflict. After the baffle plate is subjected to force, it cooperates with the insertion rod to squeeze the spring to block the end of the workbench through the baffle plate to prevent the residue from being directly discharged from the gap between the workbench plate and the collection frame.

[0016] The negative pressure machine cooperates with the connecting pipe to evacuate the collection frame, so that the collection frame is in an air-intake state, and a partition net is installed inside the collection frame to prevent food residues from entering the negative pressure machine. The collection frame is convenient for the discharge of food residues on the vertical workbench, thereby reducing the area of ​​manual cleaning of the workbench and reducing the workload of staff in cleaning the workbench.

[0024] Specifically, when in use, the device carries items used for food additive detection tests through the workbench 5, and the mounting shaft 204 can drive the connecting rod 3 to deviate. When the connecting rod 3 deviates, the height of the limiting column 101 inside the column 105 changes, so that the workbench 5 can be adapted to workers of different heights, thereby improving the adaptability of the device.
