Description

Technical Field

[0001] This utility model relates to the field of solid beverage mixing technology, and in particular to a precise metering and mixing device. Background Technology

[0002] Solid beverages refer to solid products made primarily from sugar, milk and dairy products, eggs or egg products, fruit juice or edible plant extracts, with the addition of appropriate excipients or food additives. The moisture content per 100 grams of the finished product is no more than 5 grams. They are in powder, granule or block form, such as soy crystal powder, malted milk powder, instant coffee, chrysanthemum crystals, etc. They are divided into three categories: protein-type solid beverages, ordinary solid beverages and roasted solid beverages (instant coffee). Solid beverages need to be mixed during production.

[0003] For example, Chinese patent CN209173869U discloses a solid beverage granule mixing device, including a feeding hopper, a mixing tank, a material valve, a discharge pipe, a controller, a stirring rod, a geared motor, a coupling, a spiral blade, a protrusion, and a rotating rod.

[0035] Please refer to Figures 1 to 5 As shown, a feeding weighing assembly 1031 for feeding metering is installed inside the feed pipe 103.

[0036] The feeding and weighing assembly 1031 includes a sealing rotating plate 10311 rotatably installed inside the feeding pipe 103. The top of the sealing rotating plate 10311 is provided with a receiving groove 10312. The inner wall of the receiving groove 10312 is fixedly connected with symmetrically arranged connecting springs 10313. The top of the connecting springs 10313 is fixedly connected with a connecting slide plate 10314. The top of the connecting slide plate 10314 is fixedly connected with symmetrically arranged connecting slide rods 10315.

A pressure sensor 10318 is installed at the bottom of the inner wall of the receiving groove 10312 and at a position corresponding to the abutment block 10317.

[0037] Please refer to Figures 1 to 5 As shown, a drive assembly 1032 for driving the feed weighing assembly 1031 is installed on the side of the feed pipe 103 and at the position corresponding to the feed weighing assembly 1031.

[0038] The drive assembly 1032 includes a drive frame 10321 fixedly connected to the side of the feed pipe 103, a servo motor 10322 fixedly connected to the drive frame 10321, a drive shaft 10323 fixedly connected to the output shaft of the servo motor 10322, and the side of the drive shaft 10323 near the sealing rotating plate 10311 is fixedly connected to the side of the sealing rotating plate 10311.

[0039] The pressure sensor 10318 is connected to an external PLC controller, and the PLC controller is electrically connected to the servo motor 10322. When the pressure sensor 10318 reaches a preset value, the operation of the servo motor 10322 can be controlled by the PLC controller, thereby realizing the convenient pouring of solid beverage raw materials.

[0040] Among them, the pressure sensor 10318 can be selected from the Honeywell SMV3000 series pressure sensor, which is suitable for various industrial applications and has high accuracy and reliability.

A limiting groove 10320 matching the limiting slider 10319 is provided on the inner wall of the receiving groove 10312 at the position corresponding to the limiting slider 10319. By adopting the above technical solution, the limiting slider 10319 and the limiting groove 10320 play a limiting role for the connecting slide plate 10314, thereby increasing the stability of the connecting slide plate 10314's telescopic movement.

[0044] The working principle of this utility model is as follows: the raw materials of solid beverage are put into the placement plate 10316, which can squeeze the connecting slide plate 10314 at the bottom through the placement plate 10316. The pressure value is monitored in real time by the pressure sensor 10318, so that the amount of material is accurately measured. When the amount of material reaches the preset value, the servo motor 10322 drives the drive shaft 10323 to rotate, which can drive the sealing rotating plate 10311 to flip and pour the put-in raw materials into the mixing tank 1 for mixing, thereby improving the convenience of mixing solid beverages.
