Abstract
Description
Technical Field
[0001] This utility model relates to the field of dairy product testing and sampling technology, specifically a dairy product quality testing and sampling device. Background Technology
[0002] Dairy products refer to various foods made using cow's milk or sheep's milk and their processed products as the main raw materials, with or without the addition of appropriate amounts of vitamins, minerals and other auxiliary materials, and processed under the conditions required by laws, regulations and standards. They are also called cream products. Sampling and testing are required during the production and processing of dairy products.
[0003] When using existing testing and sampling devices, it is difficult to selectively extract samples according to the testing needs when dealing with different types of dairy products. In other words, the operability is poor and the overall scope of use is limited when sampling the whole product.
[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a sampling device for dairy product quality testing. Utility Model Content
[0005] The purpose of this invention is to provide a sampling device for quality testing of dairy products to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a dairy product quality testing sampling device, comprising a dairy product box, a one-way inlet, and a one-way outlet; the dairy product box has multiple sets of dairy product compartments arranged at intervals from top to bottom, each compartment storing different types of dairy products to be tested; the upper and lower sides of the side walls of each compartment are respectively provided with one-way inlets and one-way outlets, and one-way pressure valves are installed inside the one-way inlets and outlets, which, when pressure is applied, control the external dairy products to enter through the one-way inlets. The dairy products inside are discharged through a one-way outlet. Inside the dairy product compartment, there is a piston that applies pressure to the one-way pressure valve inside the one-way outlet. When the piston applies pressure to the one-way pressure valve, it drives the one-way outlet to open, thereby causing the dairy products inside the dairy product compartment to be discharged through the one-way outlet. All the pistons are connected to a set of adjustable pressure mechanisms on the side opposite to the one-way outlet. The adjustable pressure mechanisms apply pressure to the pistons according to the sampling volume inside the dairy product compartment, thereby controlling the discharge of dairy products through the one-way outlet.
[0007] Compared with the prior art, the beneficial effects of this utility model are: by setting up multiple sets of dairy product compartments to store different types of dairy products, this device can simultaneously sample and test multiple dairy products.
[0008] By installing a piston inside the dairy product compartment, along with a one-way pressure valve inside the one-way liquid outlet and an adjustable pressure mechanism on one side of the dairy product compartment, selective sampling of dairy products with different contents can be achieved in different dairy product compartments. At the same time, the energy transmission of a single motor is fully utilized to achieve an energy-saving and efficient operation mode for this device. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] Please see Figure 1-Figure 5 A dairy product quality testing sampling device includes a dairy product box 10, a one-way inlet 12, and a one-way outlet 13. The dairy product box 10 has multiple dairy product compartments 11 spaced apart from top to bottom. Different dairy product compartments 11 store different types of dairy products to be tested. The upper and lower sides of each dairy product compartment 11 are respectively provided with a one-way inlet 12 and a one-way outlet 13. One-way pressure valves are installed inside the one-way inlet 12 and the one-way outlet 13. When pressure is applied, external dairy products are controlled to enter through the one-way inlet 12, and internal dairy products are controlled to enter through the one-way outlet 13. The product is discharged to the outlet 13. Inside the dairy product compartment 11, there is a piston that applies pressure to the one-way pressure valve inside the one-way outlet 13. When the piston applies pressure to the one-way pressure valve, it drives the one-way outlet 13 to open, and at the same time, it drives the dairy products inside the dairy product compartment 11 to be discharged along the one-way outlet 13. All the pistons are provided with a set of adjustable pressure mechanism on the side opposite to the one-way outlet 13. The adjustable pressure mechanism applies pressure to the pistons according to the sampling amount inside the dairy product compartment 11, thereby controlling the dairy products to be discharged along the one-way outlet 13.
[0020] In this embodiment of the invention, the outer end of the one-way outlet 13 is connected to a dairy product detection device, that is, by outputting dairy products along the one-way outlet 13, they can be detected by the detection device.
[0021] The piston assembly includes a piston plate 23 that moves laterally inside the dairy product compartment 11. A piston rod 21 is connected to the middle of the side of the piston plate 23 away from the one-way outlet 13. The piston rod 21 extends through the wall of the dairy product compartment 11 to the outside of the dairy product compartment 11. Springs 24 are symmetrically arranged on the piston plate 23 located on the upper and lower sides of the piston rod 21. The end of the spring 24 away from the piston plate 23 is connected to the wall of the dairy product compartment 11. When the spring 24 is in a free state, it keeps the piston plate 23 distributed on the side away from the one-way outlet 13. At the same time, in order to ensure that the piston plate 23 can be as close as possible to the inner wall of the dairy product compartment 11, a spring groove 25 is opened on the inner wall of the dairy product compartment 11 corresponding to the end of the spring 24. When the spring 24 is in a compressed state, it can be fully stored in the spring groove 25.
[0022] Specifically, a sealing plate 22 is provided at the movable connection between the piston rod 21 and the wall of the dairy product compartment 11 to maintain the seal between the inside and outside during movement;
[0023] The outer end of the piston rod 21 is set as an arc-shaped structure, which is in contact with the adjustable pressure mechanism. The elasticity of the spring 24 controls the piston plate 23 to move back and forth laterally inside the dairy product compartment 11.
[0024] In one embodiment of the present invention, the adjustable pressure mechanism includes a rotating disk 18 that is rotated and lifted and disposed on one side of the dairy product box 10. Multiple sets of radially distributed push rods 19 are uniformly installed on the outer circumferential wall of the rotating disk 18. The lengths of the multiple sets of push rods 19 vary sequentially along the circular trajectory direction. By rotating the rotating disk 18, the push rods 19 of different lengths are controlled to contact the end of the piston rod 21, thereby applying different pressures to the piston rod 21. This, in turn, controls the piston plate 23 to move different distances inside the dairy product box 11, thereby outputting dairy products of different contents. The output amount of dairy products changes positively with the length of the push rods 19.
[0025] A rotating shaft 20 is fixedly installed at the center of the rotating disk 18. A U-shaped rotating frame 17 is rotatably mounted on the rotating shaft 20. A nut 16 is connected to one side of the rotating frame 17 via a connecting rod. A vertical lead screw 15 is threaded to the middle of the nut 16. A servo motor 14 is connected to the top of the lead screw 15 via an output shaft. A guide device is provided on the nut 16 to limit its rotation. That is, when the servo motor 14 is started, it drives the output shaft to control the lead screw 15 to rotate, thereby driving the nut 16 to move up and down along the lead screw 15. Then, it drives the push bar 19 on the rotating disk 18 to contact the piston rod 21 on one side of the dairy product compartment 11 at different heights to apply pressure.
[0026] The top of the disc shaft 20 on the rotating disk 18 is connected to a rod cylinder 27 via a connecting block 26. A telescopic rod 28 is telescopically connected inside the top of the rod cylinder 27. A positioning key 29 is installed on the outer circumferential wall of the telescopic rod 28. A positioning slide rail 30 is provided on the inner wall of the rod cylinder 27 corresponding to the positioning key 29. The positioning key 29 slides axially within the positioning slide rail 30, with rotational limits. When the rotating disk 18 moves up and down, the telescopic rod 28 moves synchronously within the rod cylinder 27. Simultaneously, a helical gear 35 is installed at the top of the telescopic rod 28 via a connecting rod 31. A helical gear 4 36 is vertically meshed on one side of the helical gear 35. One side of the helical gear 4 36 is connected via a connecting rod. An electric telescopic rod 32 is connected to the end of the electric telescopic rod 32, and a helical gear 34 is connected to the end of the electric telescopic rod 32. A helical gear 33 is vertically meshed on one side of the helical gear 34. The helical gear 33 is fixed on the output shaft. The electric telescopic rod 32 is activated to control whether the helical gear 34 meshes with the helical gear 33. Then, with the help of the rotation of the output shaft, the rod cylinder 27 is driven to rotate under the rotation connection of the helical gear 33, the helical gear 34, the helical gear 35, and the helical gear 4 36, thereby controlling the rotation of the rotating disk 18. The push rods 19 of different lengths are adjusted to contact the piston rod 21 to apply pressure, thereby sampling different contents inside the dairy product warehouse 11.
[0027] The length of the lead screw 15 is greater than the height of the dairy product box 10, ensuring that the lifting and lowering range of the nut 16 can be transferred between all dairy product boxes 11.
[0028] It should be noted that the positioning of the lead screw 15, rotary disk 18, rod cylinder 27, helical gear 35, and helical gear 4 36 is not shown in the figure. However, in actual use, they can be installed using corresponding support and positioning brackets. This article does not elaborate on them, nor does it affect the smooth implementation of this technical solution.
[0029] The working principle of this utility model is as follows: In the idle state of this device, all the aforementioned driving components, referring to power elements, electrical components, and compatible power supplies, are connected via wires. The electrical connections between the various electrical components are completed in a sequential manner. The detailed connection methods are well-known in the field. The following mainly describes the working principle and process, without explaining the electrical control. During operation, different types of dairy products to be tested are placed in different dairy product compartments 11 beforehand. Then, the one-way outlet 13 is connected to the detection device, and then the servo motor 14 is started and the electric control device is activated. The telescopic rod 32, according to the output dairy products, starts the nut 16 to drive the rotating disk 18 to move up and down, moving the rotating disk 18 to the piston rod 21 on one side of the dairy product bin 11 where the dairy products are to be output. Then, the electric telescopic rod 32 is controlled to mesh the helical gear 2 34 with the helical gear 1 33, thereby driving the rod cylinder 27 to rotate, bringing the corresponding length of the push rod 19 into contact with the piston rod 21, and then pushing the piston plate 23 to move laterally along the inside of the dairy product bin 11. Then, the one-way pressure valve at the one-way liquid outlet 13 is opened, thereby inputting the dairy products into the detection device.
[0030] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
