Description

Technical Field

[0001] This utility model belongs to the field of plastic bucket technology, specifically referring to a plastic bucket mouth thread repair device. Background Technology

[0002] After a plastic bucket is molded, burrs often remain on the threads of the bucket opening in the molded area. These burrs need to be removed to avoid affecting the fit and installation of the bucket lid. The conventional repair method is to manually use a cutting tool to slowly cut along the edge of the threads. This method is inefficient and labor-intensive.

[0003] If automated equipment is used for rotary cutting of the burr, the plastic bucket needs to be secured. Because the plastic bucket is hollow, the clamping force should not be too great, otherwise it will cause deformation of the bucket. However, if the clamping force is insufficient, the friction will be insufficient, and the bucket will slip during rotational cutting, affecting the repair quality. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a plastic barrel mouth thread repair device, which at least partially solves the above problems.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a plastic bucket mouth thread repair device, including a thread repair disc, which is sleeved on the plastic bucket mouth and driven to rotate;

[0006] A clamping plate, located on the bottom wall of the plastic bucket, is driven to slide towards the threaded repair disc;

[0007] The slider is slidably disposed on the clamping plate and is distributed in at least three sets around the circumference of the thread repair disc;

[0008] The pressure plate, which is adjustable in angle, is mounted on the slider and works with the clamping plate to fix the protrusion at the bottom of the plastic bucket.

[0009] Furthermore, the present invention provides a plastic bucket mouth thread repair device, which also includes a telescopic platform. The clamping plate is located at the telescopic end of the telescopic platform, the thread repair disc is rotatably located above the telescopic platform, the end of the telescopic platform is provided with a motor, the output shaft of the motor is provided with a connecting disc, and a circumferentially distributed connecting rod is provided between the thread repair disc and the connecting disc.

[0010] Furthermore, the connecting rod is telescopically oriented, and both ends of the connecting rod are respectively hinged to the connecting disc and the threaded repair disc.

[0011] Furthermore, the connecting rod is composed of multiple rods connected end to end, and the multiple rods can adapt to and connect threaded repair discs of different radii.

[0012] Furthermore, an auxiliary frame is provided on the telescopic platform, and a telescopic rod is provided below the auxiliary frame.

[0013] Furthermore, the auxiliary frame is configured as an arc-shaped strip, and the inner side of the cross-section of the auxiliary frame is configured as an arc shape, with the arc opening facing downwards.

[0014] Furthermore, the pressure plate is hinged to the slider, and both ends of the pressure plate protrude from the sides of the slider. The side wall of the slider is provided with a side plate, and a push rod is threadedly connected to the side plate. The top of the push rod is tangent to the end of the pressure plate away from the plastic bucket.

[0015] Furthermore, the telescopic end of the telescopic platform is driven by a cylinder.

[0016] The beneficial effects of this utility model are as follows: The pressure plate clamps the protrusion at the bottom of the plastic bucket. Taking advantage of the higher structural strength of this part, the protrusion at the bottom of the plastic bucket is clamped at an angle. This can not only apply a greater clamping force and increase the friction, making the clamping of the plastic bucket more stable, but also avoid damaging the plastic bucket. Finally, the burr is removed by rotation. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown in the figure, the present invention provides a plastic bucket mouth thread repair device, including a telescopic platform 1, a clamping plate 7, a slider 10, a pressure plate 9, and a thread repair disc 2. The telescopic platform 1 has a telescopic function, and the telescopic end of the telescopic platform 1 is driven by a cylinder 8. The clamping plate 7 is provided at the telescopic end of the telescopic platform 1. The plastic bucket is horizontally fixed on the telescopic end, and the bottom wall of the bucket body 14 is attached to the side wall of the clamping plate 7 to move with the telescopic end of the telescopic platform 1. The thread repair disc 2 is rotatably located above the telescopic platform 1. The inner wall of the thread repair disc 2 is provided with threads adapted to the plastic bucket mouth. The fixed end of the telescopic platform 1 is provided with a motor 3. The output shaft of the motor 3 is provided with a connecting plate 4. A circumferentially distributed connecting rod 5 is provided between the thread repair disc 2 and the connecting plate 4. When the motor 3 rotates, it drives the thread repair disc 2 to rotate through the connecting plate 4 and the connecting rod 5.

[0027] In order to remove the burrs from the mold plate at the mouth of the plastic bucket, the thread repair disc 2 is fitted onto the mouth of the plastic bucket. When it is driven to rotate by the motor 3, the threads on the inner wall of the thread repair disc 2 will cut off the burrs, thereby completing the repair of the mouth of the bucket. During the cutting, the plastic bucket needs to be fed slowly. The cylinder 8 drives the plastic bucket on the telescopic end to be fed at a constant speed towards the thread repair disc 2.

[0028] To keep the plastic bucket fixed during rotary burr removal and prevent slippage, sliders 10 are slidably mounted on clamping plate 7. At least three sets of sliders 10 are distributed around the circumference of thread repair disc 2. Slider 10s can slide radially along the radius of their circumferential distribution to accommodate plastic buckets of different diameters. The center of each circumferentially distributed slider 10 should coincide with the central axis of the thread repair disc 2. Pressure plate 9 is adjustablely positioned on sliders 10. Figure 4As shown, the pressure plate 9 and the clamping plate 7 cooperate to clamp and fix the protrusion at the bottom of the barrel 14, and the clamping plate 7 applies a vertical pressure P to the protrusion at the bottom of the barrel 14. This clamping method can effectively utilize the high structural strength of the protrusion at the bottom of the plastic barrel 14, and clamp the protrusion at the bottom of the plastic barrel at an angle to apply a greater clamping force, so as to increase the friction and make the clamping of the plastic barrel more stable, thereby avoiding the risk of damage to the barrel 14 that may occur when clamping it on the cylindrical side wall of the barrel 14 in a conventional manner.

[0029] In some embodiments, the connecting rod 5 is telescopically oriented, and its two ends are respectively hinged to the connecting plate 4 and the threaded repair plate 2 (not shown in the figures). When repairing plastic buckets of different diameters, the threaded repair plate 2 also needs to be replaced, and the diameter of the threaded repair plate 2 changes. Since both ends of the connecting rod 5 are hinged to the connecting plate 4 and the threaded repair plate 2, the power transmission between the threaded repair plate 2 and the motor 3 can be achieved by adjusting the angle of the connecting rod 5, that is, by adjusting the distance between the connecting plate 4 and the threaded repair plate 2.

[0030] In some embodiments, the connecting rod 5 is composed of multiple rods connected end to end (not shown in the figures). The multiple rods can adapt to and connect threaded repair discs 2 of different radii. By changing the connection method of each rod, it can also adapt to the power transmission between threaded repair discs 2 of different diameters and motor 3.

[0031] In some embodiments, such as Figure 1 and Figure 2 As shown, the telescopic platform 1 is equipped with multiple sets of auxiliary frames 6, and a telescopic rod 13 is provided below the auxiliary frame 6. Before the plastic bucket is fixed to each slider 10 and pressure plate 9, the auxiliary frame 6 is used to support the plastic bucket and keep it horizontal, which facilitates the clamping operation of the pressure plate 9. The auxiliary frame 6 is set as an arc strip to adapt to the shape of the plastic bucket. At the same time, the inner side of the cross-section of the auxiliary frame 6 is set as an arc shape, and the arc opening faces downward. During the process of the plastic bucket sliding with the telescopic platform 1, some of the auxiliary frames 6 remain stationary, while the plastic bucket may have protrusions of different shapes at intervals along the height direction. The arc design with the opening facing downward can avoid hindering the relative sliding of the auxiliary frame 6 and the protrusions.

[0032] In some embodiments, such as Figure 3 As shown, the pressure plate 9 is hinged to the slider 10, and both ends of the pressure plate 9 protrude from the sides of the slider 10. The side wall of the slider 10 is provided with a side plate 11, and a push rod 12 is threadedly connected to the side plate 11. The top of the push rod 12 is tangent to the end of the pressure plate 9 away from the plastic bucket. During the clamping operation, simply rotate the push rod 12 to move it up and down. The push rod 12 can drive the end of the pressure plate 9 to move up and down, and the pressure plate 9 will rotate around the hinge point with the slider 10, thereby pressing it against the bottom protrusion of the plastic bucket, and finally clamping and fixing the plastic bucket to prevent rotation during cutting.
