Description

Technical Field

[0001] This utility model relates to a plastic bucket repair device, specifically a plastic bucket outer surface repair device after molding, belonging to the technical field of plastic bucket repair devices. Background Technology

[0002] When plastic buckets are processed by extrusion molding, burrs often appear at the mouth, which need to be removed by a trimming device. To facilitate trimming, the bucket is usually fixed by a clamp, and the entire plastic bucket is rotated by a drive assembly. The blade is fixed, thus achieving the trimming of the burrs on the plastic bucket.

[0003] However, since most plastic buckets are elastic, they are prone to deformation during rotation, which changes the distance between the plastic bucket and the blade, affecting the quality of the trimming. Therefore, a device for trimming the outer surface of a plastic bucket after molding is needed to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a device for finishing the outer surface of a plastic bucket after molding in order to solve the above problems. The driving structure drives the rotating ring to rotate on the rotating shaft. The rotating ring drives the docking structure and the blade to rotate circumferentially. The blade quickly trims the burrs on the plastic bucket, preventing deformation of the plastic bucket during rotation and improving the quality of trimming.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a plastic bucket outer surface finishing device after molding, comprising a frame and a telescopic structure at the top of the frame, a cylindrical rotating shaft installed at the bottom of the telescopic structure, a rotating ring rotatably mounted on the rotating shaft, the rotating ring being driven by a driving structure; a docking structure is fixed on the rotating ring, and a blade is fixed on the docking structure.

[0006] Preferably, the telescopic structure includes a hydraulic component, which is fixed on the frame. A base plate is fixed to the bottom end of the hydraulic component, and a rotating shaft is fixed to the bottom end of the base plate.

[0007] Preferably, four guide rods are fixed on the base plate, and the guide rods are slidably connected to the frame.

[0008] Preferably, the motor in the drive structure is fixed to the base plate, and a second gear is mounted on the output shaft of the motor. The second gear meshes with the first gear, and the first gear is fixed to the top of the rotating ring.

[0009] Preferably, the axis of the first gear coincides with the axis of the rotating shaft, and a frustum-shaped rubber sleeve is fixedly provided at the bottom end of the rotating shaft.

[0010] Preferably, the docking structure includes a sliding sleeve and a sliding rod, the sliding rod is fixed on the rotating ring, the sliding rod is located inside the sliding sleeve, and a blade is fixed on the sliding sleeve.

[0012] Preferably, a lead screw is rotatably provided on the sliding sleeve, and the lead screw is threadedly connected to the sliding rod.

[0013] The beneficial effects of this utility model are as follows: A cylindrical rotating shaft is installed at the bottom of the telescopic structure, and a rotating ring is rotatably mounted on the rotating shaft. The rotating ring is driven by a drive structure. A docking structure is fixed on the rotating ring, and a blade is fixed on the docking structure. The distance between the blade and the plastic bucket in the vertical direction is adjusted by the telescopic structure, and then the distance between the blade and the burr edge of the plastic bucket in the horizontal direction is adjusted by the docking structure. This facilitates the quick alignment of the blade with the burr edge of the plastic bucket. The rotating ring is driven to rotate on the rotating shaft by the drive structure. The rotating ring drives the docking structure and the blade to rotate circumferentially. The blade quickly trims the burr edge of the plastic bucket, preventing deformation of the plastic bucket during rotation and improving the quality of trimming. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 As shown, a plastic bucket outer surface finishing device after molding includes a frame 1 and a telescopic structure 2 at the top of the frame 1. A cylindrical rotating shaft 6 is installed at the bottom of the telescopic structure 2. A rotating ring 301 is rotatably mounted on the rotating shaft 6 and driven by a driving structure 3. A docking structure 4 is fixed on the rotating ring 301, and a blade 5 is fixed on the docking structure 4. The telescopic structure 2 includes a hydraulic component 203. The hydraulic component 203 is fixed on the frame 1. A base plate 202 is fixed at the bottom of the hydraulic component 203. The rotating shaft 6 is fixed at the bottom of the base plate 202. The hydraulic component 203 drives the base plate 202 to move up and down. The rotating shaft 6 at the bottom of the base plate 202 drives a rubber sleeve to fix the plastic bucket, improving the fixing effect. Four guide rods 201 are fixed on the base plate 202 to make the movement of the base plate 202 more stable. The guide rods 201 are slidably connected to the frame 1.

[0021] As a technical optimization of this utility model, the docking structure 4 includes a sliding sleeve 401 and a sliding rod 402. The sliding rod 402 is fixed on the rotating ring 301. The sliding sleeve 401 and the sliding rod 402 are slidably connected. The sliding sleeve 401 is bolted to the blade 5. A lead screw 403 is rotatably provided on the sliding sleeve 401. The lead screw 403 is threadedly connected to the sliding rod 402. When the lead screw 403 is rotated, the lead screw 403 threadedly drives the sliding rod 402 to slide between the sliding sleeve 401, so that the blade 5 moves toward the plastic bucket.

[0022] As a technical optimization of this utility model, the motor 304 in the drive structure 3 is fixed to the base plate 202. A second gear 303 is installed on the output shaft of the motor 304. The second gear 303 meshes with the first gear 302. The first gear 302 is fixed to the top of the rotating ring 301. The axis of the first gear 302 coincides with the axis of the rotating shaft 6. The motor 304 drives the second gear 303 to rotate, the second gear 303 drives the first gear 302 to rotate, and the first gear 302 drives the rotating ring 301 to rotate, thereby driving the blade 5 to rotate on the side of the plastic bucket to trim the plastic bucket, preventing deformation of the plastic bucket during rotation and improving the quality of trimming.

[0023] In use, the electrical components are first connected to the control box to form an electrical connection with the outside. When trimming the plastic bucket, the plastic bucket is placed on the frame 1 and then fixed by a fixing fixture, so that the center of the plastic bucket's axis coincides with the center of the rotating shaft 6. The hydraulic component 203 drives the base plate 202 to move downward. The hydraulic component 203 is preferably a hydraulic cylinder or a pneumatic cylinder. The base plate 202 drives the rotating shaft 6 to move downward. The rotating shaft 6 drives the rubber sleeve to abut against the top of the plastic bucket, further fixing the plastic bucket and preventing deformation. When the rubber sleeve is in full contact with the plastic bucket, the blade 5 is positioned at the edge of the plastic bucket. Rotating the lead screw 403 causes the threaded drive of the sliding rod 402 to slide between the sliding sleeve 401, moving the blade 5 towards the plastic bucket. The motor 304 drives the second gear 303 to rotate, which in turn drives the first gear 302 to rotate. The first gear 302 then drives the rotating ring 301 to rotate, thereby causing the blade 5 to rotate on the side of the plastic bucket, trimming the edge and preventing deformation during rotation, thus improving the quality of the trimming.
