[0053] Embodiment 1:

[0054] As shown in Figures 1 to 3 The utility model discloses a kind of material collecting and cleaning device, comprising:

[0055] Material guiding unit is used to guide packaging bag to move;Including control unit (not shown in drawing), still including respectively installed on material guiding unit:

[0056] Induction unit is used to convert the packaging bag sensed into electrical signal and pass to control unit;

[0057] Blowing unit is used to form air flow barrier on material guiding unit, and blow empty packaging bag out of material guiding unit;

[0058] Magnetic separation unit is located upstream of blowing unit;

[0059] Among them, control unit is connected with induction unit, cleaning unit and magnetic separation unit respectively, control unit is used to control magnetic separation unit adsorption / stop adsorption packaging bag, and control blowing unit blowing / stop blowing, when blowing unit stops blowing, magnetic separation unit stops adsorption packaging bag.

[0060] The working principle of the material collecting and cleaning device of the present application is:

[0061] The automatic packaging machine sends the packaging bag loaded with surgical blades out through a conveying belt, and the packaging bags on the conveying belt are generally placed horizontally, and the material guiding unit is installed at the end of the conveying belt;

[0062] When the packaging bag on the conveying belt falls to the material guiding unit, the packaging bag gradually moves downward under the action of gravity, and when the packaging bag passes through the sensing unit, the sensing unit sends a signal to the control unit to control the blowing unit and the magnetic separation unit to start, and the magnetic attraction area and the blowing area are formed in turn from high to low on the material guiding unit;

[0063] When the packaging bag passes through the magnetic attraction area, if the packaging bag is loaded with surgical blades, the packaging bag is magnetically attracted to the material guiding unit, and after the blowing area stops blowing, the magnetic attraction area stops attracting the packaging bag, and then the packaging bag slides out along the material guiding unit after passing through the blowing area;

[0064] When the empty packaging bag passes through the magnetic attraction area, since the packaging bag does not contain surgical blades, it will not be attracted by the magnetic attraction area, and the packaging bag will directly slide into the blowing area and be blown out by the airflow in the blowing area to achieve the purpose of removing empty packages;

[0065] In the above technical solution, the control unit is an external PLC control system;

[0066] By adopting the above technical solution, the empty packages generated in the packaging process of surgical blades can be effectively cleaned through the cooperation of each unit without the participation of manual labor, which is simple and efficient.

[0067] Embodiment 2:

[0068] The present embodiment provides a material collecting and waste removing device, which further has the following technical features in addition to the technical solutions of the above embodiments.

[0069] Further, the material guiding unit comprises:

[0070] a support plate 2;

[0071] a material guiding plate 1 fixedly installed on the front side of the support plate 2;

[0072] Among them, the two ends of the support plate 2 protrude from the material guiding plate 1 and are fixedly installed with support cantilevers 3 for connecting and fixing with the external conveying belt support.

[0073] In the above technical solution, the support plate is located below the front side of the output end of the conveying belt and is horizontally inclined;

[0074] By adopting the above technical solution, the material guiding plate can be firmly installed on the output end of the conveying belt through the arrangement of the support plate and the support cantilever.

[0075] Embodiment 3:

[0076] This embodiment provides a material collecting and waste removal device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0077] Furthermore, a material receiving unit is provided below the material guide plate 1, and the material receiving unit includes:

[0078] The material receiving bracket 4 is located on the ground;

[0079] There are two conveyor chain groups 5, which are rotatably mounted on both sides of the upper end of the material receiving bracket 4 and are arranged parallel to each other. Each conveyor chain group 5 includes two conveyor chains parallel to each other.

[0080] Material receiving parts 6, each conveyor chain group 5 is fixedly installed with a plurality of spaced material receiving parts 6 on its circumference;

[0081] The material receiving member 6 is in a U-shaped structure. Specifically, the material receiving member 6 includes a bottom plate fixedly connected to the chain, and limit plates located on both sides of the bottom plate.

[0082] In the above technical solution, the conveyor chain groups are driven by motors arranged on the material receiving bracket;

[0083] By adopting the above technical solution, the material receiving piece can receive the packaging bag with the surgical blade that slides out through the material guide plate. By adjusting the position of the support frame on the ground, the material receiving piece can be aligned with the lower edge of the material guide plate, so as to accurately receive the material.

[0084] Each receiving piece can carry several packaging bags. When the receiving pieces under the guide plate are fully stacked, the empty receiving pieces can be moved under the guide plate by the rotation of the chain, which is convenient for collecting the packaging bags.

[0085] Example 4:

[0086] This embodiment provides a material collecting and waste removal device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0089] The cylinder 8 is fixedly mounted on the cylinder bracket 7;

[0090] The permanent magnet 9 is located between the cylinder 8 and the guide plate 1 and is fixedly connected to the output conveying end of the cylinder 8;

[0091] When the output end of the cylinder 8 extends, the permanent magnet 9 is adjacent to the guide plate 1, and when the output end of the cylinder 8 is reset, the permanent magnet 9 and the guide plate 1 are away from each other;

[0092] The permanent magnet 9 is located downstream of the support plate 2 .

[0093] By adopting the above technical solution, when the sensing unit detects the packaging bag and feeds back to the control unit, the control unit controls the cylinder to extend, so that the permanent magnet can approach the guide plate, so that the area between the sensing unit and the blowing unit on the guide plate can generate sufficient magnetic field strength, forming a magnetic attraction zone to attract the packaging bag with the blade. When the control unit controls the air outlet unit to stop air discharge, it controls the cylinder to retract, and the permanent magnet moves away from the guide plate. The magnetic field strength of the magnetic attraction zone is weakened, and the packaging bag cannot be attracted, that is, the attraction of the previously attracted packaging bag is stopped, thereby preventing the packaging bag with the surgical blade from being blown out by the blowing unit.

[0094] In addition, the magnetic separation unit is located on the rear side of the guide plate. Apart from magnetically attracting the packaging bags, it will not interfere with the movement of the packaging bags.

[0108] In the above technical solution, the long groove is vertically arranged on the guide plate;

[0109] In the above technical solution, the support plate and the guide plate are fixed by bolts;

[0110] In the above technical solution, there may be multiple air blowing pipes, and the air inlet ends of the air blowing pipes are connected to an external air pump or an air storage tank;

[0116] In the above technical solution, the baffle plate 1 is formed by bending one side of the guide plate;

[0117] By adopting the above technical solution, after the guide plate with the oblique structure is installed in conjunction with the conveyor belt, since the conveyor belt is transporting in a straight line, the conveying direction of the guide plate is offset to the right. When the packaging bag in a horizontal state falls into the guide plate, the packaging bag will change to a vertical posture and slide down against the baffle plate.

[0118] Through the structural layout of proximity sensor, permanent magnet and long slot adjacent to the baffle plate, the packaging bag can stably pass through the induction unit, magnetic separation unit and blowing unit in sequence without missing or misscreening.
