The invention belongs to the technical field of a packaging machine, and particularly relates to a packaging size limiting device. The packaging size limiting device comprises a packaging machine and a power supply, wherein the packaging machine is provided with a stander, a hydraulic oil cylinder, an oil pump motor, a contactor and a starting switch, wherein the contactor is provided with a coil, one side of the stander is provided with a scaleplate, a guide pole is correspondently arranged by the side of the scaleplate, the guide pole is provided with a photoelectric switch, the photoelectric switch is connected with the coil of the contactor in series through a signal line, a control end of the contactor is connected with the oil pump motor, and the power supply, the starting switch and the photoelectric switch are sequentially connected with one another in series. The corresponding circuit is controlled through the sensing characteristics of the photoelectric switch so as to meet the requirement on the packaging thickness, the overpressure on a product can be prevented, the product can be prevented from being damaged, and the packaging efficiency is improved; and a UPS (uninterrupted power supply) power supply is arranged between the power supply and a power supply end of the contactor, so that the packaging process can be prevented from being influenced by the sudden power failure.
Description
technical field [0001] The invention belongs to the technical field of packaging machinery, and in particular relates to a packaging size limiting device. Background technique [0002] At present, most of the balers are only different in the tonnage of the baling pressure, and the limitation of the baling thickness is basically handled according to the experience of the operator. Some packaged products that require high packaging size and cannot cause damage to the product need to be controlled by the worker's operating level and proficiency, the accuracy is not high, and the labor intensity is high. Contents of the invention [0003] In order to overcome the deficiencies in the above-mentioned technologies, the object of the present invention is to provide a packaging size limiting device, which uses the inductive characteristics of the photoelectric switch to complete the precise control of the packaging thickness. [0004] The technical scheme that the present inventio...
