Description

Technical Field

[0001] The invention relates to the technical field of fire extinguisher production equipment, and in particular to a full-automatic fire extinguisher production line. Background Art

[0002] After the fire extinguisher has been tested for water, the screen printing process can be started only when the surface water vapor has dried. After the surface ink has dried, the production label and qualified mark can be posted and hung. The specific process of traditional operation is as follows: first conduct a water test, then manually transfer each fire extinguisher to an open space and place it there, wait for large water droplets on the surface to drip, then wipe off the remaining water and dirt with a towel, and naturally dry the surface water vapor; then manually put each fire extinguisher into the screen printing machine for printing, and after printing, take it down and place it on the open space to dry the ink naturally; finally, manually affix a product production label and hang a certificate of conformity sign to each fire extinguisher. The whole process requires multiple manual handling, which is labor-intensive, time-consuming, and occupies a large amount of production space.

[0003] Therefore, nowadays, it is necessary to use a conveyor chain to send the fire extinguisher to the fire extinguisher automated production line for dewatering, drying, silk screen printing, UV curing and other processes in sequence. However, it is found in production that there are still many problems with the existing automated production line. For example, after the air tightness test of the water tank is completed, it is necessary to wipe the fire extinguisher dry in the process of drying, which cannot be applied to different fire extinguisher specifications, thereby failing to meet the effect of cleaning and drying the fire extinguisher and affecting subsequent processing. At the same time, the quality of the two-color printing is affected due to insufficient positioning accuracy during the two-color printing of the fire extinguisher, and most of the processed fire extinguishers need to be collected one by one manually at the tail end of the production line, which is time-consuming and labor-intensive. If the person leaves the workstation, the fire extinguisher will fall or the conveyor belt sensor will work, which may cause the entire production line to be unable to continue to operate smoothly, seriously affecting production efficiency. Therefore, the degree of automation is low. For this reason, a fully automatic fire extinguisher production line is proposed to overcome the above problems. Summary of the invention

When cleaning is completed, when the fire extinguisher lifting handle is rotated to the required angle, the photoelectric sensor 401 senses the positioning, and the driving motor 30 stops working.

[0043] The setting of the counterweight block 44 in the printing mechanism of the first printing device 7 and the second printing device 8 will make the movement of the main support plate 47 more stable and reliable, ensuring the printing quality, driving the lifting motor 49 to work in coordination with the rotation of the screw rod and at the same time using the cooperation of the slider and the slide rail to drive the main support plate 47 to move up and down in a straight line to the required working position, the main lifting knife plate cylinder 52 will work to adjust the working height of the printing knife plate 54, the auxiliary lifting knife plate cylinder 53 will work to adjust the printing depth of the printing knife plate 54 to meet the printing requirements, the rodless cylinder 55 works to adjust the working position of the screen mounting plate 56, thereby adjusting the working position of the printing screen mounting frame 59, and at the same time, the screen mounting block 58 slides in coordination with the screen mounting guide column 57 and the locking bolt to manually adjust the printing screen mounting frame 59 to the required processing position, and the setting of the rodless cylinder 55 will replace the traditional rod cylinder setting to save installation space.

[0044] The working output end of the auxiliary push cylinder 79 in the lifting brake mechanism 13 extends out, pushes open the reduction wheel transmission plate 76, thereby driving the nylon reduction wheel 75 to separate from the rubber wheel 74 to achieve a loosening effect. When the working output end of the auxiliary push cylinder 79 contracts, the reduction wheel transmission plate 76 is reset by the force of the reset spring 77, thereby driving the nylon reduction wheel 75 and the rubber wheel 74 to be pressed and fitted together, playing a certain braking role. When the reduction wheel transmission plate 76 is active, the movement of the slider and the guide rail is more stable and reliable. The setting of the lifting brake mechanism 13 will ensure the accuracy and stability of the fire extinguisher during printing positioning, so that the fire extinguisher will not be affected by the inertia of the dry powder in the bottle when it is rotated and positioned, thereby improving its printing quality.

[0045] The handwheel screw 64 in the rotary positioning mechanism 12 can rotate to adjust the position of the motor mounting frame 63, thereby adjusting the working position of the servo motor 67. At the same time, a motor mounting adjustment movable plate 66 is arranged in the motor mounting frame 63. The motor mounting adjustment movable plate 66 is slidably connected to the motor mounting frame 63. The motor mounting adjustment movable plate 66 is threadedly connected to the handwheel screw. The upper and lower positions of the motor mounting adjustment movable plate 66 can be adjusted to adjust the working position of the servo motor 67. The servo motor 67 drives the positioning lever 69 to rotate, thereby moving the fire extinguisher lifting handle, driving the fire extinguisher to rotate to the desired position, and at the same time cooperates with the proximity switch 71 for precise positioning so that the servo motor 67 stops working.

[0046] The bottle erecting device 9 drives the cylinder 86 to make the fire extinguisher bottle placing base 82 rotate 90 degrees with the hinged shaft 81 as the rotation center, so that the fire extinguisher bottle placing base 82 is vertically erected, and the bottle standing slide 84 slides on the bottle standing slide guide rail 83 through inertia, so that the fire extinguisher is erected on the auxiliary conveyor belt 14. The setting of the bottle standing limit placement block 85 will achieve the effect of limiting the fire extinguisher, ensuring the stability of the fire extinguisher, so that it can be better erected on the auxiliary conveyor belt 14.

[0047] The working principle of this specific embodiment is as follows: first, the hand wheel screw 25 is rotated and adjusted according to the demand, so that the transmission slider 26 makes a linear motion on the support slide rail 24, thereby driving the cleaning hair roller 19 to move up and down to the required working position, and the position of the motor mounting frame 63 can be adjusted by rotating the hand wheel screw 64 according to the demand, so as to adjust the servo motor 67 to the required working position. When the fire extinguisher is output from the air tightness detection water tank to the input end of the conveyor belt 1, the proximity switch on the lever 42 senses and works, so that the conveyor belt 1 works and the fire extinguisher enters the first cleaning device 5. The fire extinguisher is input above the jacking device 11. At this time, the lever 42 corresponds to the photoelectric sensor at the tail of the fire extinguisher, so that the push cylinder 3 in the push device 10 9 works to drive the push plate 40 to push the fire extinguisher, so that the tail of the fire extinguisher presses against the rod 42, and the push plate 40 is reset. Then the lifting cylinder 28 in the lifting device 11 works to lift the fire extinguisher, and the driving motor 30 works to provide power to rotate the guide wheel 33, thereby driving the fire extinguisher on the guide wheel mounting plate 34 to rotate. At the same time, the three-phase asynchronous motor 22 cooperates with the reducer 21 to make the cleaning roller 19 always in a rotating working state, and the rotation direction of the guide wheel 33 is opposite to that of the cleaning roller 19. At this time, the fire extinguisher performs a rotating cleaning process between the guide wheel 33 and the cleaning roller 19. When a cleaning process is completed, the lifting cylinder 28 works to descend to make the fire extinguisher separate from the cleaning roller 19. At the same time, when the fire extinguisher pressure handle is rotated to the required angle , the photoelectric sensor 401 senses the position, and the drive motor 30 stops working at this time, achieving the effect of positioning the fire extinguisher. The fire extinguisher falls into the conveyor belt 1 again, and the conveyor belt 1 is operated. It is dried once through the first drying device 2, and then rotated and cleaned twice through the second cleaning device 6. After the processing is completed, the conveyor belt 1 is operated to make the fire extinguisher enter the first printing device 7. When the fire extinguisher reaches the top of the lifting brake mechanism 13, the conveyor belt 1 stops working, and the lifting and adjusting cylinder 72 in the lifting and braking mechanism 13 works to make the roller support frame 73 rise and lift the fire extinguisher. At this time, the piston push rod of the auxiliary push cylinder 79 is in a retracted state, so that the nylon reduction wheel 75 and the rubber wheel 74 are fitted to reach the braking state, and then the proximity switch at the tail of the fire extinguisher senses The tail tightening cylinder should be operated so that the rear conical head pushes the fire extinguisher forward until the fire extinguisher moves so that its lifting and pressing handle reaches the front conical head 68 in the rotating positioning mechanism 12. At this time, the rear conical head and the front cone 68 are on the same center line to achieve the effect of positioning the fire extinguisher. The tail tightening cylinder retreats. At this time, the positioning lever 69 is just above the mouth of the fire extinguisher as the origin position. Then the servo motor 67 works to make the positioning lever 69 rotate and move the fire extinguisher lifting and pressing handle. When the positioning lever 69 rotates to the sensing position of the proximity switch 71, the servo motor 67 stops working, so that the fire extinguisher rotates to the initial printing position to achieve the printing positioning effect and prepare for a printing. The positioning lever 69 rotates 270° in the opposite direction away from the fire extinguisher lifting and pressing handle. Before printing,The auxiliary push cylinder 79 works to push out the piston rod to drive the reduction wheel transmission plate 76 to move and then drive the nylon reduction wheel 75 to separate from the rubber wheel 74 to achieve the loosening effect and ensure the printing quality. During printing, the printing mechanisms in the first printing device 7 and the second printing device 8 both adjust the working position of the main support plate 47 by driving the lifting motor 49, and then drive the screen mounting plate 56 to move left and right through the rodless cylinder 55. The auxiliary lifting knife plate cylinder 53 works to drive the printing knife plate 54 to rise and fall, so that the printing knife plate 54 and the printing screen on the printing screen mounting frame 59 cooperate to perform printing. After printing is completed, the printing screen and the printing knife plate 54 are reset and returned. When printing is completed, the positioning lever 69 returns to the original position, and the nylon reduction wheel 75 is again attached to the rubber wheel 74 through the auxiliary push cylinder 79 to achieve the braking effect. The lifting adjustment cylinder 72 descends so that the fire extinguisher that has completed one print is again transported to the second drying device 3 through the conveyor belt 1. After the secondary drying, the fire extinguisher enters the second printing device 8 for secondary printing. The process is the same as the primary printing process. After the secondary printing is completed, the fire extinguisher is transported to the third drying device 4 through the conveyor belt 1 for the third drying. After the third drying, the fire extinguisher is transported to the bottle stand device 9 through the conveyor belt 1. The fire extinguisher bottle placement chassis 82 is rotated 90 degrees with the hinge shaft 81 as the rotation center by driving the cylinder 86, so that the fire extinguisher bottle placement chassis 82 is vertically erected. The bottle stand slide 84 slides on the bottle stand slide guide 83 by inertia, so that the fire extinguisher is erected on the auxiliary conveyor belt 14. The driving cylinder 86 works and contracts to reset the fire extinguisher bottle placement chassis 82, waiting for the next fire extinguisher to enter, and finally the processed fire extinguisher is transported to the required position. During the entire processing process, all stations are carried out simultaneously. The conveyor belt 1 will be suspended when the station is working, and the conveyor belt 1 will continue to operate after all stations are processed.
