Description

Technical Field

[0001] The utility model belongs to the technical field of bottle cap supply for packaging lines, and particularly relates to a cap supply device for a liquid pesticide packaging line. Background Art

[0002] Liquid pesticide packaging lines generally include a cap sorting device, a cap conveying device, and a cap screwing device. The cap sorting device first arranges the caps in a uniform direction, then the cap conveying device conveys the caps to the bottle mouth at the packaging location, and the cap screwing device screws the caps onto the medicine bottles.

[0003] When a dual centrifugal cap sorting device is used, such as the Chinese utility model patent with publication number CN219525284U, the centrifugal motor in the dual centrifugal cap sorting device is always in operation as long as the packaging line is running, which has the problem of high power consumption. Utility Model Content

[0004] The technical problem to be solved by the utility model is to make up for the deficiencies of the prior art and provide a cap supply device for a liquid pesticide packaging line with low power consumption.

[0005] To solve the above technical problems, the technical solution of the present utility model is:

[0006] A cap supply device for a liquid pesticide packaging line comprises a dual-circular capping machine, a bottle cap conveying track and a photoelectric induction relay delay module; the bottle cap conveying track comprises a horizontal portion, a transition arc portion and a vertical portion connected in sequence, wherein the horizontal portion is higher than the vertical portion, and a light-through hole is provided on the transition arc portion; the horizontal portion is fixedly connected to the dual-circular capping machine and communicates with the discharge port of the dual-circular capping machine; the photoelectric induction relay delay module comprises a photoelectric sensor, a controller and a normally closed relay; the photoelectric sensor is fixedly connected to the transition arc portion, and the sensing light emitted by the photoelectric sensor passes through the light-through hole to sense the bottle caps in the transition arc portion; the normally closed relay is electrically connected to the switch of the dual-circular capping machine.

[0007] Furthermore, when the photoelectric sensor of the photoelectric induction relay delay module senses an object, the controller starts timing. After t seconds, the normally closed relay is controlled to disconnect, and the motor of the dual-clutch psychological cover machine stops moving; when the photoelectric sensor does not sense an object, the normally closed relay is automatically energized, and the motor of the dual-clutch psychological cover machine is powered on.

[0008] Furthermore, a stud is fixed on the transition arc portion of the bottle cap conveying track, and the switch frame is fixedly connected to the transition arc portion of the bottle cap conveying track via the through hole K, the stud and the nut.

[0009] The beneficial effects achieved by the utility model are as follows: the photoelectric sensor of the photoelectric induction relay delay module is cleverly arranged in the transition arc part of the bottle cap conveying track, and the bottle caps are transported in the transition arc part and the vertical part by falling under their own gravity, so that when the vertical part and the transition arc part are both in a full cap state, the double-disconnection capping machine stops working, which directly saves about 50% of electricity and reduces production costs.

DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0020] A capping device for a liquid pesticide packaging line includes a dual-separation capping machine 1, a bottle cap conveying track 3, and a photoelectric induction relay delay module 4. The dual-separation capping machine belongs to the prior art and is commercially available, so its working principle and product structure will not be described in detail here.

[0021] like Figure 4 As shown, the bottle cap conveying track 3 includes a horizontal part 301, a transition arc part 302 and a vertical part 303 connected in sequence, and the horizontal part 301 is higher than the vertical part 303, and a light hole 304 is provided on the transition arc part 302. The horizontal part 301 is fixedly connected to the double-separation psychological capping machine 1 and is communicated with the discharge port 2 of the double-separation psychological capping machine 1; a stud 404 is fixed on the transition arc part 302.

[0022] The photoelectric induction relay delay module 4 comprises a photoelectric sensor 401, a controller, and a normally closed relay. The photoelectric sensor 401 is fixed to the switch frame 402, which is fixedly connected to the transition arc portion 302 of the bottle cap conveyor track 3 via a through-hole K4021, a stud 404, and a nut 403. The sensing light emitted by the photoelectric sensor 401 passes through the light hole 304 to sense the bottle caps 5 in the transition arc portion 302. The normally closed relay is electrically connected to the switch of the dual-isolation capping machine 1, controlling the start and stop of the motor of the dual-isolation capping machine 1. The control logic is as follows: when the photoelectric sensor 401 of the photoelectric induction relay delay module 4 senses an object, the controller starts a timer. After two seconds, the normally closed relay is controlled to open, stopping the motor of the dual-isolation capping machine 1. If the photoelectric sensor 401 no longer senses an object, the normally closed relay automatically closes, energizing the motor of the dual-isolation capping machine 1. The photoelectric induction relay delay module is a conventionally used commercial product.

[0023] Use of this embodiment:

[0024] Since the normally closed relay of the photoelectric induction relay delay module 4 is "normally closed", after power is turned on, the motor of the double-centrifugal capping machine 1 is powered on and the arranged bottle caps 5 enter the bottle cap conveying track 3 one by one from the discharge port 2 of the double-centrifugal capping machine 1. The conveyance of the bottle caps 5 in the horizontal part 301 is pushed forward by the centrifugal force of the double-centrifugal capping machine 1, and the conveyance of the bottle caps 5 in the transition arc part 302 and the vertical part 303 is caused by their own gravity.

[0025] The first stage: the lower part of the vertical part 303 is missing the cover, such as Figure 4 As shown, the bottle cap 5 slides off the photoelectric sensor 401 instantly. The sensing time of the photoelectric sensor 401 is much shorter than the set delay time of 2 seconds. The double separation capping machine 1 continues to work and arranges and conveys the bottle caps 5.

[0026] The second stage: the vertical part 303 and the transition arc part 302 are fully covered, such as Figure 6As shown, if the full cap state is maintained for more than 2 seconds, the photoelectric sensor 401 senses the bottle cap 5 for a sensing time of more than 2 seconds, then the controller of the photoelectric induction relay delay module 4 will control the normally closed relay to disconnect, and the motor of the dual-isolation capping machine 1 will stop moving.

[0027] The third stage: the lower part of the vertical portion 303 is again missing the cover, such as Figure 8 As shown, the bottle caps 5 in the transition arc portion 302 slide down to fill the position, which makes the time for the photoelectric sensor 401 to sense the bottle caps 5 much shorter than the set delay time of 2 seconds. The dual-centrifugal capping machine 1 continues to work and arranges and conveys the bottle caps 5.

[0028] Advantages of this embodiment: When the vertical portion 303 and the transition arc portion 302 of the bottle cap conveying track 3 are both in a full cap state, the dual separation capping machine 1 stops working, directly saving about 50% of electricity and reducing production costs.
