Description

Technical Field

[0001] This utility model relates to the field of multi-head combination scale technology, and in particular to a material distribution mechanism for a multi-head combination scale. Background Technology

[0002] Computerized combination scales, also known as computerized scales, multi-head combination scales, electronic scales, and electronic multi-head scales, work by vibrating material from the upper feed chute down through the main vibrating plate to the linear vibrating plates at each head. When the first hopper (called the storage hopper) is empty, the material is vibrated from the linear vibrating plate to the storage hopper according to the set vibration time. When the weighing hopper below the storage hopper is empty after being filled, the storage hopper opens, and material is discharged into the weighing hopper, which then begins weighing. Existing multi-head combination scales often encounter problems when weighing viscous materials such as pickled vegetables, cooked food, and preserved vegetables. The downward resistance of the material is high, and some material tends to adhere to the distribution system, causing problems such as uneven material distribution and overloading of individual hoppers.

[0003] Existing technology, such as the material dispensing mechanism of a multi-head combination scale disclosed in patent document CN202320896254.0, relates to the field of multi-head combination scales. It includes a material dispensing tray with a material dispensing chute. A first mounting groove is formed within the material dispensing chute, and a second mounting groove is formed on one side of the first mounting groove. A swinging mechanism is provided within the material dispensing chute. The swinging mechanism includes a movable shaft, a slanted slide plate, a connecting armature, a spring, and an electromagnet. The movable shaft is movably mounted within the material dispensing chute, and the slanted slide plate is fixedly mounted on the movable shaft. The connecting armature is fixedly mounted at the bottom of the slanted slide plate. The spring is located in the first mounting groove, and the electromagnet is located in the second mounting groove. A dispersing mechanism is located in the middle of the material dispensing tray. When the electromagnet is activated, it attracts the connecting armature, causing the spring to store force. After the spring stores force, it can deactivate the electromagnet. After the electromagnet is deactivated, the spring returns to its original position. During the spring's return process, the slanted slide plate swings up and down, facilitating the downward movement of materials and preventing material from adhering to the material dispensing chute.

[0004] However, the above technical solution still has some technical problems. For example, because the material distribution chute is set up, the two side walls of the material distribution chute are higher than the swing mechanism. This will cause some material to come into contact with the two side walls of the material distribution chute first after it is guided to move in all directions by the dispersing mechanism, resulting in material sticking and affecting the subsequent weighing steps.

[0027] In actual use, by using the reversing component to make the inclined guide plate 220 and the scraper 240 rotate in opposite directions, the effect of material distribution is increased under the action of centrifugal force.

[0028] In some specific embodiments of this utility model, it may also have the following additional technical features: the reversing assembly includes a drive gear 261 and a driven gear 262. The drive gear 261 is fixedly sleeved on the drive shaft 230. An internal gear ring 221 is provided at the bottom of the inclined guide plate 220.
