Description

Technical Field

[0001] This utility model relates to the field of packaging bottle filling production line technology, specifically to a filling and feeding device for eye drop packaging bottles. Background Technology

[0002] Existing eye drop packaging bottles require bottle sorting and feeding before filling to neatly arrange and transport the disordered bottles to the filling station. The structure can be referenced in utility model patent application number 202322192761.9: a bottle sorting machine for health food packaging, which uses an inclined turntable, a limiting groove on the inclined plate, and an annular retaining ring structure to achieve the bottle sorting process after the packaging bottles are dropped. Because this type of structure can only enter the limiting groove when the packaging bottles are at a certain angle, the efficiency of the packaging bottles entering the limiting groove is reduced. Therefore, there is a need for a feeding device with a vibrating annular retaining ring structure to accelerate the adjustment of the packaging bottle's angle, thereby increasing the efficiency of the packaging bottles entering the limiting groove. Utility Model Content

[0003] The technical problem to be solved by this utility model is how to provide a filling and feeding device for eye drop packaging bottles.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A filling and feeding device for eye drop packaging bottles, the key technology of which includes: The inclined support has a cylindrical boss at its upper end, and several threaded holes are spaced apart on the edge of the upper end face of the boss. A turntable is rotatably mounted on the boss portion. Its upper end face is evenly provided with several limiting grooves in the circumferential direction, and its lower part is provided with an annular groove. Several top blocks are evenly provided at the bottom of the annular groove. The retaining ring, which is C-shaped, is provided along the edge of the upper surface of the boss. It includes a movable retaining ring corresponding to the bottom of the turntable and two fixed retaining rings symmetrically arranged on both sides of the movable retaining ring. The movable retaining ring is provided on the boss by a number of elastic limiting components. A number of paddles are provided on the inner side of the movable retaining ring at intervals corresponding to the annular groove. When the turntable rotates, the top block and the paddles lift up, thereby causing the movable retaining ring to rise. The elastic limiting components are used to drive the lifted movable retaining ring to descend rapidly.

[0005] In one embodiment of this utility model, the cross-section of the movable retaining ring is L-shaped, with its vertical part used to surround the packaging bottle and its horizontal part abutting against the upper end face of the protrusion.

[0006] In one embodiment of this utility model, the elastic limiting component includes a threaded portion, a smooth rod portion, and a nut connected in sequence. A limiting sleeve is fitted on the smooth rod portion near the nut. The threaded portion passes through the through hole on the horizontal portion and connects to the threaded hole. A compression spring is fitted on the smooth rod portion between the limiting sleeve and the upper end face of the horizontal portion. After the movable retaining ring rises along the smooth rod portion, it compresses the compression spring. After the top block moves away from the paddle, the compression spring pushes the horizontal portion to make the movable retaining ring descend rapidly.

[0007] In one embodiment of this utility model, the limiting sleeve abuts against the outer side of the movable retaining ring to limit the distance between the limiting sleeve and the turntable.

[0008] In one embodiment of this utility model, the distance between the upper end of the top block and the bottom of the annular groove is greater than the distance between the lower end of the paddle and the bottom of the annular groove.

[0009] In one embodiment of this utility model, the top block is hemispherical in shape, and the side of the paddle facing the top block has a smoothly transitioning chamfered structure.

[0010] As one embodiment of this utility model, the retaining ring is provided with several weight-reducing holes.

[0011] In one embodiment of this utility model, a rotary drive assembly is provided on the inclined support, a key is provided on the output shaft of the rotary drive assembly, a locking part is provided on the key, a key hole corresponding to the key is provided at the center of the turntable, and a locking cap is detachably provided on the locking part. After the turntable is sleeved on the key through the key hole, the locking cap is applied to restrict the turntable from sliding along the axial direction of the key.

[0012] The beneficial effects of adopting the above technical solution are as follows: The turntable of this invention has a movable retaining ring at its bottom and an annular groove at its bottom. Multiple top blocks are arranged in the annular groove, and a paddle is arranged on the corresponding top block inside the movable retaining ring. When the turntable rotates, the top blocks lift the paddle inside the movable retaining ring, thereby causing the movable retaining ring to rise. Then, the movable retaining ring is driven to descend rapidly by an elastic limiting component, so that the movable retaining ring completes one up-and-down vibration. During the rotation of the turntable, the movable retaining ring vibrates cyclically to help the packaging bottles at the bottom to quickly position themselves at the correct angle, increasing the efficiency of the packaging bottles entering the limiting groove.

Detailed Implementation

[0020] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0021] like Figure 1The illustrated eye drop bottle filling and feeding device includes: a slanted support 200 mounted on a support box 100, a turntable 300 inclinedly mounted on the slanted support 200, and a retaining ring (in this embodiment, the retaining ring has several weight-reducing holes) mounted along the edge of the turntable 300. The upper surface of the turntable 300 has several limiting grooves 301 evenly provided in the circumferential direction. A material discharge channel 800 is provided above the area enclosed by the retaining ring and the lower part of the turntable 300 to receive the messy packaging bottles conveyed from the previous process. In this embodiment, the retaining ring is C-shaped, and a receiving and conveying channel is provided on the edge of the notch on one side to receive the packaging bottles placed in the limiting groove 301. This embodiment mainly focuses on the structure of the movable retaining ring for quick bottle sorting, and the structure of the receiving and conveying channel will not be described in detail. In addition, the limiting groove 301 is semi-circular or slightly curved, and combined with the structure of the eye drop packaging bottle with one end pointed and the other end cylindrical, when the notch is in place, the inverted packaging bottle or it falls from here, without affecting the packaging bottles in the lower area of ​​the tray from entering the limiting groove 301.

[0022] See Figure 2 The upper end face of the inclined support 200 is provided with an inclined surface 201, and a cylindrical boss 202 is provided on the inclined surface 201, so that the upper end face of the boss 202 is inclined relative to the horizontal plane. A number of threaded holes 203 are provided at intervals on the edge of the upper end face of the boss 202 for passing through bolt assembly fixing rings.

[0023] See Figure 4 and Figure 5 The turntable 300 is rotatably mounted on the boss 202. Its upper end face is evenly provided with a plurality of limiting grooves 301 in the circumferential direction, and its lower part is provided with an annular groove 303. A plurality of top blocks 304 are evenly provided at the bottom of the annular groove 303.

[0024] See Figure 2 and Figure 3 The retaining ring includes a movable retaining ring 600 corresponding to the lower part of the turntable 300 and two fixed retaining rings 600 symmetrically arranged on both sides of the movable retaining ring 600. The movable retaining ring 600 is set on the boss portion 202 by a plurality of elastic limiting components 700. A plurality of paddles 603 are spaced apart on the inner side of the movable retaining ring 600 corresponding to the annular groove 303. The angle difference between two adjacent paddles 603 corresponds to the angle difference between two adjacent top blocks 304. When the turntable 300 rotates, the top blocks 304 abut against the paddles 603. Then, the top blocks 304 lift the paddles, thereby driving the movable retaining ring 600 to rise. The elastic limiting components 700 are used to drive the lifted movable retaining ring 600 to descend rapidly. Figure 5In this embodiment, the distance between the upper end of the top block 304 and the bottom of the annular groove 303 is greater than the distance between the lower end of the paddle 603 and the bottom of the annular groove 303. The top block 304 is generally hemispherical, and the paddle 603 has a smoothly transitioning chamfered structure on the side facing the top block 304.

[0025] Preferably, the movable retaining ring 600 and the fixed retaining ring 500 are integrally formed and are both set on the boss portion 202 by the elastic limiting component 700.

[0026] See Figure 5 and Figure 6 The movable retaining ring 600 has an L-shaped cross-section, with its vertical portion 601 used to surround the packaging bottle and its horizontal portion 602 abutting against the upper end face of the boss portion 202. The elastic limiting component 700 includes a threaded portion 705, a smooth rod portion 701, and a nut 702 connected in sequence. A limiting sleeve 703 is fitted on the smooth rod portion 701 near the nut 702. The threaded portion 705 passes through a through hole on the horizontal portion 602 and connects to the threaded hole 203. A compression spring 704 is fitted on the smooth rod portion 701 between the limiting sleeve 703 and the upper end face of the horizontal portion 602. When the movable retaining ring 600 rises along the smooth rod portion 701, it compresses the compression spring 704. After the top block 304 moves away from the paddle 603, the compression spring 704 pushes the horizontal portion 602 to make the movable retaining ring 600 descend rapidly.

[0027] See details Figure 5 The limiting sleeve 703 abuts against the outer side of the movable retaining ring 600 to limit the distance between the limiting sleeve 703 and the turntable 300, ensuring that the shape of the packaging bottle temporary storage channel formed between the limiting groove 301 and the turntable 300 remains unchanged.

[0028] See Figure 4 The inclined support 200 is provided with a rotary drive assembly 400, which adopts a servo motor structure. The output shaft of the rotary drive assembly 400 is provided with a key 401, and the key 401 is provided with a locking part 402. The center of the turntable 300 is provided with a key hole 302 corresponding to the key 401. A locking cap 403 is detachably provided on the locking part 402. After the turntable 300 is sleeved on the key 401 through the key hole 302, the locking cap 403 is applied to restrict the turntable 300 from sliding along the axial direction of the key 401.
