Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model.

[0029] In the related art, the detection in the production process of dairy products is important in multiple core dimensions and is directly related to product quality. By detecting and analyzing various parameters in the production process in real time, such as temperature, pH value, fat content, etc., enterprises can timely adjust the production process, optimize the production flow, improve production efficiency and product qualification rate. At the same time, accurate detection data can also help enterprises accurately control raw material consumption and formula adjustment, reduce waste, and lower production costs. During the semi-finished product detection process in the production process, a variety of detection reagents need to be added, usually manually. Due to the slow operation speed of manual labor and insufficient personnel, it cannot meet the detection requirements.

[0030] To solve the above problems, the present utility model provides a liquid dispensing device and a detection line body to solve the problems of slow liquid dispensing speed and inability to meet the detection requirements during the liquid detection process.

[0031] The following will describe the embodiments of the present utility model in conjunction with Figures 1 to 4 , the embodiments of the present utility model will be described.

[0032] According to an embodiment of the present utility model, on the one hand, a liquid dispensing device is provided. As shown in Figures 1 to 3 , it includes a pump body 1, a liquid injection head 2, a displacement mechanism 3, and a controller. There are multiple pump bodies 1, and the input ends of the multiple pump bodies 1 are respectively used to insert into different reagent bottles; there are multiple liquid injection heads 2, and the multiple liquid injection heads 2 correspond to and are connected to the output ends of the multiple pump bodies 1 one by one, and the multiple liquid injection heads 2 are arranged at intervals along the first direction; at least one bracket 301 is arranged on the displacement mechanism 3, and the bracket 301 can slide reciprocally along the first direction, and the bracket 301 is used to support the mixing container; the controller is electrically connected to the multiple pump bodies 1 to control the start and stop of the multiple pump bodies 1, the controller is electrically connected to the multiple liquid injection heads 2 to control the opening and closing of the multiple liquid injection heads 2, and the controller is electrically connected to the displacement mechanism 3 to control the moving position of the bracket 301.

[0033] Specifically, the pump body 1 can be a diaphragm pump, a gear pump, a centrifugal pump, a plunger pump, etc., preferably a diaphragm pump; the liquid injection head 2 is an existing product, provided with an automatic control switch and can be controlled by the signal of the controller; the controller can be a device such as a computer, a control chip, a single-chip microcomputer, etc.; the above "electrically connected" means an electrical signal connection through wires or cables.

[0034] It should be noted that the liquid injection head 2 in the first direction can be partitioned, and the liquid injection heads 2 in different partitions are used to proportion different reaction reagents, so that one or more detection containers can be respectively placed on multiple sliding brackets 301 to realize the simultaneous preparation of multiple reagents.

[0035] Taking the detection of semi-finished product M by reagent A as an example, the use of the liquid preparation device will be described. Among them, reagent A requires raw material B, raw material C, and raw material D to be proportioned by volume ratio of 2:1:2.

[0036] During the specific working process, the input ends of the three pump bodies 1 are respectively connected to the reagent bottles of raw material B, raw material C, and raw material D, and the input end of another pump body 1 is connected to the bearing container of semi-finished product M. A detection bottle is placed on the bracket 301 of the displacement mechanism 3. Then, the controller controls the bracket 301 to stop and receive the corresponding raw materials under the liquid injection head 2 of raw material B, the liquid injection head 2 of raw material C, and the liquid injection head 2 of raw material D in sequence. When each raw material's liquid injection head 2 injects liquid into the detection bottle, the controller controls the opening and closing of each liquid injection head 2 to inject a specified injection volume into the injection bottle, specifically: 20 ml of raw material B, 10 ml of raw material C, and 20 ml of raw material D, thus completing the preparation of reagent A. Then, the controller controls the detection bottle to move under the liquid injection head 2 of semi-finished product M and injects 5 ml of semi-finished product M, thus completing the cooperation of detecting semi-finished product M with reagent A.

[0037] In this embodiment, by arranging multiple liquid injection heads 2 at intervals in the first direction, and providing different reagents through the correspondingly connected pump bodies 1, and placing the detection container on the bracket 301 to reciprocate in the first direction to the lower part of the liquid injection heads 2 of different reagents for liquid injection, the automatic operation of liquid preparation is realized, with fast liquid preparation speed, good accuracy, and no need to set up manual liquid preparation actions, thus being able to meet the liquid preparation requirements of detection tests and improve the detection speed.

[0038] In one embodiment, as Figure 1 shown, the displacement mechanism 3 includes a slide rail 302, at least one sliding seat 303, and at least one bracket 301. The sliding seat 303 is slidably arranged on the slide rail 302. A driving motor is arranged on the sliding seat 303 to drive it to slide on the slide rail 302. A bracket 301 is arranged on the sliding seat 303, and the brackets 301 correspond to the sliding seats 303 one by one. The driving motor is electrically connected to the controller.

[0039] Specifically, the driving motor is a stepping motor, etc.; the bracket 301 can be made of plastic plates bolted together; the slide rail 302 can be a plastic slide rail 302 or a steel slide rail 302.

The bottom plate 3013 is fixedly connected to the sliding seat 303.

[0042] Specifically, the bottom plate 3013, the intermediate plate 3012, and the top plate 3011 are plastic plates and are connected by four columns distributed in a rectangle. Usually, the cross-sectional area of the first fixing hole 30111 and the cross-sectional area of the third fixing hole 30113 are both smaller than the cross-sectional area of the second fixing hole 30112, and the shape of the fourth fixing hole 30121 is the same as the shape of the second fixing hole 30112.
