Description

Technical Field

[0001] The invention relates to the technical field of leather deodorization, and in particular to a spray device for removing leather odor in a long-term manner and a use method thereof. Background Art

[0002] The leather industry covers the main industries such as leather making, shoe making, leather clothing, leather goods, fur and its products, as well as supporting industries such as leather chemicals, leather hardware, leather machinery, and accessories. Leather not only includes animal skins that have been denatured and not easy to rot after physical and chemical processing such as depilation and tanning, but also includes some synthetic leather, recycled leather, etc. Recycled leather is made by crushing the waste skins and genuine leather scraps of various animals and mixing chemical raw materials. Its surface processing technology is the same as that of genuine leather shaved leather and embossed leather. Its characteristics are neat leather edges, high utilization rate, and low price; but the leather body is generally thicker and relatively harder. It is generally used to make shaped process products such as briefcases, trolley bags, club covers, and belts.

[0003] Due to the characteristics of the production process of regenerated leather, it will produce odor. The leather needs to be passed through a treatment box after production, and the odor needs to be removed by spraying liquid medicine in the treatment box. However, in the actual operation process, the rolled leather needs to be manually pulled out, passed through the treatment box, and finally wrapped around the reel of the winder. However, when manually passing the leather through the treatment box, it is rather troublesome. The leather needs to be inserted into the treatment box from the entrance, and then the hand is stretched into the treatment box from the exit of the treatment box to pull out the leather, and then it can be rolled on the reel of the winder for winding. In the case of a large width of the treatment box, the leather inserted into the treatment box needs to be pulled out from the exit with the help of tools such as long-handled clamps, which is rather troublesome; at the same time, after the leather roll on the unwinding rack is released, when replacing the next leather roll to be deodorized, it is rather troublesome to install the reel of the leather roll to be treated on the placement rack.

[0020] S4, spray deodorization:

[0021] In S3, when the leather enters the deodorizing box and the push rod motor is started, the water pump is started at the same time, so that the water pump sucks the liquid medicine in the medicine box, and sprays the liquid medicine on both sides of the leather through the pipeline from the multiple atomizing nozzles, thereby removing the odor of the leather;

[0022] S5, Rolling leather:

[0023] The leather passing through one side of the deodorizing box in S3 is passed over the upper part of the corresponding second guide roller and the lower part of the first guide roller, and is wound on the reel of the winder, and the winder is started, and then the four push rod motors are started to shorten the output rods and separate the multiple rotating tubes from the leather, so that the atomized liquid can better deodorize both sides of the leather;

[0024] S6. Replace the leather roll to be processed:

[0025] After the leather on the reel on the unwinding mechanism is released, pull the pull ring to disengage the card block from the card slot on the installation cover, then open the two installation covers, remove the reel, put the reel with the leather to be processed on it, and then follow the steps S1-S5 to process.

The spray device for removing leather odor in a long-term manner according to claim 1, characterized in that: Two first guide rollers and two second guide rollers are rotatably mounted on the support frame, and the two first guide rollers are respectively matched with the two second guide rollers.

6. The spray device for removing leather odor in a long-term manner according to claim 4, characterized in that: Through holes are provided on both sides of the deodorizing box, and a visualization window is provided on one side of the deodorizing box.

7. The method for using the spray device for long-term removal of leather odor according to any one of claims 1 to 6, characterized in that: The steps include: S1. Place the leather roll to be processed: Place the roll of thicker and harder recycled leather to be processed on the half bearings on the two supports, and then cover the two installation covers while pulling the pull ring to merge the half bearings on the supports and the installation covers. At this time, release the pull ring, and under the elastic force of the spring, the block at one end of the pull rod is inserted into the slot on the installation cover; S2, Automatic leather conveying: Start the motor, and drive the corresponding first roller to rotate through the two sprockets and the chain, and then drive the first conveyor belt to rotate slowly. Under the elastic force of the compression spring, the second conveyor belt is pressed on the first conveyor belt, so the first conveyor belt drives the second conveyor belt to move, and pulls out one end of the leather on the support to bypass the bottom of the corresponding first guide roller and the top of the second guide roller, and smoothly extends into the gap between the first conveyor belt and the second conveyor belt, and contacts the first conveyor belt and the second conveyor belt. Driven by the friction between the moving first conveyor belt and the second conveyor belt, the leather moves between the first conveyor belt and the second conveyor belt along with the first conveyor belt and the second conveyor belt; S3, through the deodorizing box: When the leather slowly moved by the first conveyor belt and the second conveyor belt enters the deodorizing box from the through hole on one side of the deodorizing box, the four push rod motors are immediately started to extend the output rods, drive the multiple rotating tubes on the two lower horizontal columns to rise, and drive the multiple rotating tubes on the two upper horizontal columns to fall, so that the rotating tubes move the leather forward horizontally and accurately come out from the through hole on the other side of the deodorizing box; S4, spray deodorization: In S3, when the leather enters the deodorizing box and the push rod motor is started, the water pump is started at the same time, so that the water pump sucks the liquid medicine in the medicine box, and sprays the liquid medicine on both sides of the leather through the pipeline from the multiple atomizing nozzles, thereby removing the odor of the leather; S5, Rolling leather: The leather passing through one side of the deodorizing box in S3 is passed over the upper part of the corresponding second guide roller and the lower part of the first guide roller, and is wound on the reel of the winder, and the winder is started, and then the four push rod motors are started to shorten the output rods and separate the multiple rotating tubes from the leather, so that the atomized liquid can better deodorize both sides of the leather; S6. Replace the leather roll to be processed: After the leather on the reel on the unwinding mechanism is released, pull the pull ring to disengage the card block from the card slot on the installation cover, then open the two installation covers, remove the reel, put the reel with the leather to be processed on it, and then follow the steps S1-S5 to process.
