Description

Technical Field

[0001] The utility model belongs to the technical field of automatic counting of plastic bags, in particular to an automatic counting device for plastic bags. Background Art

[0002] Plastic bag counters are usually used in supermarket operations to record the number of plastic bags used. The use of counters can help supermarkets accurately record the consumption of plastic bags, effectively control costs, promote environmental protection, and reduce plastic bag waste. The weighing and counting method is a common method of calculating the amount of plastic bags used. The specific method is to first weigh a certain number of plastic bags to get the total weight, and then calculate the average weight of each plastic bag. Finally, the total weight is divided by the average weight of a single plastic bag to get the number of plastic bags. When calculating the usage, the reduced weight is divided by the average weight of a single plastic bag to get the number of plastic bags used.

[0003] However, this technical method requires pre-calculating the average weight of a single plastic bag when counting plastic bags of different weights, which is rather troublesome and requires a high degree of precision for the weighing equipment. To this end, we propose an automatic plastic bag counting device. Utility Model Content

[0005] Preferably, there are four support columns, which are respectively installed at four corners of the bottom of the outer shell.

[0006] Preferably, a plurality of springs are evenly spaced between the telescopic end of the cylinder and the roller frame. The springs can generate a buffer between the roller and the measuring wheel to prevent the roller from rising excessively and damaging the measuring wheel.

[0007] Preferably, a support rod is installed on the support column on the side away from the side plate, and the support rod can prevent the plastic bag from sagging.

[0008] Preferably, the surfaces of the measuring wheel and the roller are both provided with anti-skid sleeves, and the anti-skid sleeves are made of rubber material. The provision of the anti-skid sleeves can prevent the plastic bag from slipping between the roller and the measuring wheel.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] First, put the plastic bag onto the mounting frame, lead out one end of the plastic bag, pass it between the roller and the measuring wheel and place it on the support rod, control the extension of the cylinder through the control panel, and then drive the roller to rise, clamp the plastic bag between the roller and the measuring wheel, and then input the length of a single plastic bag through the control panel. When pulling out the plastic bag, the plastic bag drives the measuring wheel to rotate, and then drives the photoelectric sensor to rotate around the second rotating axis, so that it can periodically receive the light emitted by the light source, and calculate the number of plastic bags pulled out according to the number of times the light is received and the length of one rotation cycle of the photoelectric sensor, and according to the length of the plastic bag. When replacing plastic bags of different sizes and types, you only need to measure the length of a single plastic bag with a ruler and set it through the control panel, so that you can conveniently and accurately calculate the amount of plastic bags used during use.
