Description

A protective clothing folding and extrusion device Technical Field

[0001] The utility model relates to the technical field of article compression, in particular to a device for squeezing protective clothing after folding. Background Art

[0002] After the protective clothing is produced, it needs to be folded and the folded protective clothing needs to be squeezed and exhausted to reduce the volume of the protective clothing and facilitate packing.

[0003] After the traditional protective clothing is folded, the folded protective clothing is transported to the designated position by a conveyor, and then the lifting mechanism that moves up and down drives the pressure plate to squeeze the protective clothing. The conveying mechanism transports the extruded protective clothing to the designated position and puts it into a plastic packaging bag, and the opening of the plastic packaging bag is heat-sealed. In order to ensure the sterile environment of the protective clothing, most plastic packaging bags are sealed bags. This extrusion packaging method of extrusion first and then sealing will cause the plastic packaging bag to contain more gas, which cannot greatly reduce the packaging volume. In addition, the plastic packaging bag is easily compressed and cracked due to the presence of gas. In order to solve this problem, a new type of protective clothing folding and extrusion equipment is proposed.

[0004] Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a protective clothing folding and then extruding device, which is used to solve the problem that common extrusion equipment adopts the method of first extruding and then sealing, which may cause a lot of gas to remain in the plastic packaging bag.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A protective clothing folding and extrusion device comprises a conveyor for conveying plastic packaging bags, a frame is arranged horizontally above the conveyor, a push rod is arranged vertically at the central axis position of the frame, the lower end of the piston rod of the push rod is fixedly connected to the connecting rod, the lower end of the connecting rod is rotatably connected to a horizontally arranged rotating shaft, the rotating shaft is rotatably connected to an axle seat, the lower end of the axle seat is fixedly connected to a pressure plate, the lower surface of the pressure plate is provided with an elastic buffer pad, an arc-shaped guide rod is movably inserted on the connecting rod, and a support spring is movably sleeved on the arc-shaped guide rod, the upper end of which is supported on the surface of the connecting rod and the lower end is supported on the surface of the pressure plate.

[0008] Preferably, a stop block is provided at the upper end of the arc-shaped guide rod.

[0009] Preferably, a limit block is horizontally provided at the lower end of the connecting rod.

[0010] Preferably, the pressure plate is movably mounted via bolts and an elastic buffer pad.

[0011] Preferably, the arc center corresponding to the arc-shaped guide rod is located on the axis of the rotating shaft.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The utility model provides a pressure plate with one end higher than the other end and an elastic buffer pad on the push rod piston rod. The contact area between the pressure plate and the elastic buffer pad and the plastic packaging bag gradually increases, so that the gas in the plastic packaging bag is squeezed from the bottom of the bag to the bag opening for discharge, and the protective clothing in the plastic packaging bag is squeezed and exhausted, and the excess gas in the plastic packaging bag is discharged to a large extent. When the plastic packaging bag is subsequently pressurized, the plastic packaging bag is less likely to burst, and the volume of the plastic packaging bag is smaller, and the volume occupied during boxing is also smaller, which is convenient for packing and boxing. The utility model solves the problem that a large amount of gas is easily retained in the plastic packaging bag due to the common extrusion equipment adopting the method of first extruding and then sealing.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] As shown in Figures 1-3, the present invention provides a technical solution: a protective clothing folding and extrusion device, comprising a conveyor 1 for conveying plastic packaging bags 2, a frame 3 is horizontally arranged above the conveyor 1, and a push rod 4 is vertically arranged at the center axis position of the frame 3;

[0020] The lower end of the piston rod of the push rod 4 is fixedly connected to the connecting rod 5, and a limit block 503 is horizontally set at the lower end of the connecting rod 5. The rotation of the pressure plate 6 is limited by the limit block 503 to prevent the pressure plate 6 from rotating too much and affecting the normal reset of the pressure plate 6. The lower end of the connecting rod 5 is rotatably connected to a horizontally arranged rotating shaft 501, and the rotating shaft 501 is rotatably connected to a shaft seat 502. The lower end of the shaft seat 502 is fixedly connected to the pressure plate 6. The pressure plate 6 is movably installed with the elastic buffer pad 7 by a bolt 601, which is convenient for disassembly and replacement of the elastic buffer pad 7.

[0021] An elastic buffer pad 7 is provided on the lower surface of the pressure plate 6, and an arc-shaped guide rod 8 with its bottom end supported on the upper surface of the pressure plate 6 is movably inserted on the connecting rod 5. The arc center corresponding to the arc-shaped guide rod 8 is located on the axis of the rotating shaft 501, which ensures the smooth rotation of the pressure plate 6. A stop block 801 is provided on the upper end of the arc-shaped guide rod 8, and the rotation of the arc-shaped guide rod 8 is limited by the stop block 801 to prevent the arc-shaped guide rod 8 from falling off from the connecting rod 5.

[0022] Working principle:

[0023] The plastic packaging bag 2 is placed on the conveyor belt of the conveyor 1 for transportation, and the push rod 4 drives the pressure plate 6 and the elastic buffer pad 7 to rise and fall. When descending, the end of the elastic buffer pad 7 with a lower vertical height first contacts the bottom of the plastic packaging bag 2 during the descent process. The pressure plate 6 is in contact with the plastic packaging bag 2 and is subjected to force, causing the pressure plate 6 to rotate around the rotating shaft 501, and the arc-shaped guide rod 8 moves in the connecting rod 5 and the support spring 9 is compressed and deformed. During the descent process of the elastic buffer pad 7, the contact area with the plastic packaging bag 2 increases, and the gas in the plastic packaging bag 2 is squeezed from the bottom of the bag to the bag opening, thereby squeezing the plastic packaging bag 2.
