Description

Technical Field

[0001] This utility model relates to the technical field of plastic bottle label removal machines, specifically a plastic bottle label removal machine with an adjustable spacing blade assembly. Background Technology

[0002] Plastic bottle label removers are mainly used to separate the bottle body from the label paper of plastic bottles. They are widely used in PET production lines, especially in the pre-treatment process before pulverization. Their function is to ultimately reduce the PVC content in the PET flakes. The plastic bottle label remover uses a high-speed rotating spindle to drive particle steel blades to peel the label off the plastic bottle. After the label is peeled off, it is separated from the bottle body through a bellows separation chamber; the label paper is blown out, while the bottle body falls directly down.

[0003] In some plastic bottle label removers, the blade assembly is mostly fixedly installed inside the machine. However, due to the different specifications of plastic bottles, the blade assembly cannot be adapted to different bottle sizes, thus affecting the label removal effect. Therefore, it does not meet the existing needs. To address this, we propose a plastic bottle label remover with an adjustable spacing blade assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a plastic bottle label removal machine with an adjustable spacing blade assembly, so as to solve the problem that the blade assembly of most plastic bottle label removal machines mentioned in the background art is fixedly installed inside the label removal machine. However, due to the different specifications of plastic bottles, the blade assembly cannot be adapted to different bottle sizes, thus affecting the label removal effect of plastic bottles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic bottle label removal machine with an adjustable spacing blade assembly, comprising a label removal machine, an inlet connected through one side of the upper end of the label removal machine, a wind box separation chamber provided at the upper end of the label removal machine on the side away from the inlet, and a bottle body outlet connected through the bottom end of the label removal machine on the side away from the inlet. The inside of the label removal machine is connected to a main shaft driven by a motor. An annular groove is formed on the outer surface of the main shaft near the middle. A threaded rod is fixedly connected between the two sides of the inner wall of the annular groove. Several sliding rings are slidably connected to the outer surface of the threaded rod and the outer surface of the annular groove. Several fixed seats are fixedly connected to the outer surface of each sliding ring. A label removal scraper is movably connected to the end of each fixed seat away from the sliding ring.

[0006] Preferably, a feeding blade is provided on one side of the outer surface of the main shaft and below the feed inlet, and a discharge blade is provided on the outer surface of the end of the main shaft away from the feeding blade and above the bottle body discharge outlet.

[0007] Preferably, each of the sliding rings has a threaded sleeve rotatably connected to both sides of its outer surface via a rotating shaft, and the threaded sleeve rotates on the outer surface of the threaded rod.

[0008] Preferably, the fixed base has a movable groove inside, a sliding plate is slidably connected inside the movable groove, and a spring is fixedly connected between one side of the sliding plate and the inner wall of the movable groove.

[0009] Preferably, a connecting rod is fixedly connected to the side of the sliding plate away from the spring, and one end of the connecting rod extends through to the outside of the fixed seat. The end of the connecting rod extending through to the fixed seat is fixedly connected to one side of the label removal scraper.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention utilizes the threaded sleeves on both sides of the outer surface of each sliding ring to rotate the threaded sleeves on the outer surface of the threaded rod via the rotating shaft. This causes the sliding ring equipped with the label removal scraper to slide along the inner wall of the annular groove, thus facilitating the adjustment of the distance between each label removal scraper according to the specifications of the plastic bottle. Then, through the elastic connection of the label removal scraper between the connecting rod and the inner wall of the movable groove via a spring, the label removal scraper fits more closely to the outer surface of the plastic bottle and peels off the label.

The inside of the label removal machine 1 is driven by a motor 5 to connect to a main shaft 6. An annular groove 601 is opened on the outer surface of the main shaft 6 near the middle. A threaded rod 9 is fixedly connected between the two sides of the inner wall of the annular groove 601. Several sliding rings 10 are slidably connected to the outer surface of the threaded rod 9 and the outer surface of the annular groove 601. Several fixed seats 12 are fixedly connected to the outer surface of each sliding ring 10. A label removal scraper 16 is movably connected to the end of each fixed seat 12 away from the sliding ring 10.

[0018] Each sliding ring 10 has a threaded sleeve 11 rotatably connected to both sides of its outer surface via a rotating shaft. The threaded sleeve 11 is threadedly rotated on the outer surface of the threaded rod 9. By rotating the threaded sleeve 11 on both sides of the outer surface of each sliding ring 10, the threaded sleeve 11 is threadedly rotated on the outer surface of the threaded rod 9 via the rotating shaft, and the sliding ring 10 with the label removal scraper 16 is driven to slide along the inner wall of the annular groove 601, so as to facilitate the adjustment of the distance between each label removal scraper 16 according to the specifications of the plastic bottle.
