Description

Technical Field

[0001] The invention relates to the technical field of rubber hose molding equipment, in particular to a rubber hose extrusion molding device for processing box rubber rollers. Background Art

[0002] Laser printers use the physical and chemical principles of light, electricity, and heat to output text or images through interaction. The basic process can be divided into seven steps: charging, exposure, development, transfer, fixing, cleaning, and de-charging. First, the surface of the photosensitive drum is evenly charged by the charging roller. The laser scanner emits modulated laser light containing image information to the photosensitive drum, forming an electrostatic latent image corresponding to the image to be copied on the surface of the photosensitive drum. Then, the toner from the developing roller is adsorbed on the surface of the photosensitive drum to convert the electrostatic latent image into a visible image. As the photosensitive drum rotates and the positive voltage applied to the back of the recording medium such as paper by the transfer roller, the negatively charged toner that forms the visible image on the surface of the photosensitive drum is attracted, and the visible image formed by the toner is transferred to the recording medium such as paper. Then it enters the fixing assembly formed by the heating roller and the pressure roller. Under the action of heat and pressure, the toner particles melt into the fibers of the recording medium, so that the visible image formed by the toner is completely solidified on the recording medium, completing the basic imaging action.

[0003] In the above imaging process, the quality of the charging roller and the developing roller of the processing box is an important factor in ensuring the imaging quality. The charging roller or the developing roller usually has such a structure, with a metal core shaft with good conductivity in the middle, and a layer of conductive or semi-conductive foamed or non-foamed rubber tube coated on the outside of the metal core shaft. Because the core shaft is covered with a rubber tube, the charging roller and the developing roller are collectively referred to as rubber rollers.

[0004] For the production of rubber hoses for rubber rollers, the extrusion method can be used for molding. First, the rubber and other materials are mixed evenly, and then extruded through a tubular die through a rubber extruder. The existing rubber extruder has a single extrusion through hole, and can only mold and produce one rubber hose at the same time, which has low production efficiency. In addition, the head temperature of the existing rubber extruder is too high, and the mold mouth is prone to aging rubber. The aging rubber accumulates in the tube, which is difficult to detect and remove, and is prone to cause serious quality problems. Summary of the invention

The first conveying belt 73 is sleeved between the first active roller 76, the first driven roller 74 and the first support roller 75. The first support roller 75 is located between the first active roller 76 and the first driven roller 74. The axis of the first support roller 75 is located above the first driven roller 74, and the axis of the first active roller 76 is located below the first driven roller 74. The first driven roller 74 is arranged close to the flange 66.

[0057] The second conveyor belt 79 is sleeved between the second active roller 710, the second driven roller 712, the two second support rollers 711 and the third support roller 713. The two second support rollers 711 are located between the second active roller 710 and the second driven roller 712.

The second active roller 710 is arranged close to the first active roller 76. The third support roller 713 is located below the second active roller 710 and the second driven roller 712. The driving mechanism 72 drives the first active roller 76 and the second active roller 710 to rotate, so that the first conveyor belt 73 and the second conveyor belt 79 move synchronously in the same direction. The two light sensors 714 are located on both sides of the second conveyor belt 79 respectively, and the two light sensors 714 are located at one end of the second conveyor belt 79 away from the first conveyor belt 73.

[0058] The rubber hose 11 extruded by the head mechanism 6 is located on the first conveyor belt 73 and the second conveyor belt 79. As the head mechanism 6 continues to extrude the rubber hose 11, the driving mechanism 72 drives the first active roller 76 and the second active roller 710 to rotate, so that the first conveyor belt 73 and the second conveyor belt 79 move synchronously in the same direction. The moving speed of the first conveyor belt 73 and the second conveyor belt 79 is consistent with the speed of the rubber hose 11 extruded by the head mechanism 6. When the optical sensor 714 senses the free end of the formed rubber hose 11, the cutter control mechanism 78 controls the cutter 77 to move downward in the vertical direction and abut against the pad 715, thereby cutting off the rubber hose 11.

The two light sensors 84 are respectively located on both sides of the conveyor belt 82, and the two light sensors 84 are located at the other end of the conveyor belt 82 away from the flange 66.

[0063] The rubber hose 11 extruded by the die head mechanism 6 is located on the conveyor belt 82. As the die head mechanism 6 continues to extrude the rubber hose 11, the conveying control mechanism controls the moving speed of the conveyor belt 82 to be consistent with the speed of the die head mechanism 6 extruding the rubber hose 11. When the light sensor 84 senses the free end of the formed rubber hose 11, the cutter control mechanism 81 controls the cutter 83 to move downward in the vertical direction to cut off the rubber hose 11.

[0064] The conveyor belt 82 of the cutting mechanism 8 in the hose extrusion molding device 2 of this embodiment receives the hose 11 extruded by the head mechanism 6, and controls the cutter 83 through the cutter control mechanism 81 to cut the hose 11 according to the actual production requirements for the length of the hose 11, thereby realizing fully automated production and greatly improving production efficiency. At the same time, the conveyor belt 82 is arranged parallel to the horizontal direction, and the conveying control mechanism controls the moving speed of the conveyor belt 82 to be consistent with the speed of the hose 11 extruded by the head mechanism 6, so that the molding accuracy is high and the quality of the extruded hose 11 is stable. Moreover, the structure of the cutting mechanism 8 in the hose extrusion molding device 2 of this embodiment is simple, and the production process is simple, which greatly saves production costs.
