Automatic solid material weighing and canning machine

Abstract

The invention discloses an automatic solid material weighing and canning machine. The machine comprises a frame, a transmission mechanism, a bottle conveying mechanism, a feeder and an automatic scale group, wherein the bottle conveying mechanism is arranged on the frame and connected with and driven by the transmission mechanism; an automatic scale group bracket is arranged at the lower end of the automatic scale group and fixedly arranged on the frame; and the feeder is positioned above the bottle conveying mechanism and arranged on the automatic scale group bracket. The machine has the characteristics that materials are accurately weighed and can be accurately discharged and canned at high speed according to a set weight parameter, so that waste is avoided; a large drive plate continuously runs, and the feeder is driven to quickly perform tracking feeding by a servo motor, so that mechanical wear caused by the frequent start and stop of the large drive plate is avoided, and canning efficiency is improved; the feeder is light in weight, small in inertia force and accurately positioned; and the servo motor is controlled to specify a station for feeding by a photoelectric switch and a programmable logic controller (PLC), so that empty bottles are not output, and canning is not performed at a bottle-free station.

Description

technical field [0001] The invention relates to the field of food processing equipment, in particular to an automatic weighing and filling machine for solid materials. Background technique [0002] At present, domestic food cans are mostly processed by manual measurement and manual canning. This manual operation requires a lot of manpower, and the speed of canning is slow, which affects production efficiency. In addition, manual measurement is not accurate enough and has large errors. It is impossible to ensure that the quality of materials in bottles and cans is within the required range, which is likely to cause waste of materials; although the volumetric canning machines currently used abroad have improved the speed of canning, there are still problems with inaccurate feeding, and the filling of cans The large rotary dial of the machine adopts the way of intermittent operation to realize canning, and the speed of intermittent operation is fixed.

[0002] At present, domestic food cans are mostly processed by manual measurement and manual canning. This manual operation requires a lot of manpower, and the speed of canning is slow, which affects production efficiency. In addition, manual measurement is not accurate enough and has large errors. It is impossible to ensure that the quality of materials in bottles and cans is within the required range, which is likely to cause waste of materials; although the volumetric canning machines currently used abroad have improved the speed of canning, there are still problems with inaccurate feeding, and the filling of cans The large rotary dial of the machine adopts the way of intermittent operation to realize canning, and the speed of intermittent operation is fixed. When it is used together with the computer multi-head scale, the multi-head scale needs to be controlled by the single-chip computer according to the weight of a single block or single bucket of solid materials. Combining the results of calculation to determine the blanking, so the blanking time is not a fixed time, so that when the two cooperate, there will be coordination errors, delays and other phenomena, resulting in low output; the frequent activation of the rotary large dial will cause impact wear on the gears, etc. Larger; the different inertia forces under light load and heavy load lead to inaccurate stop position, resulting in material leakage
