Description

Technical Field

[0001] This utility model relates to the technical field of plastic bottle production equipment, specifically a feeding device for plastic bottle cap production. Background Technology

[0002] Plastic bottle caps are an indispensable component of plastic bottles. A feeding device for plastic bottle cap production can continuously and stably supply plastic bottle caps from storage boxes to the production line, ensuring continuous operation and avoiding production interruptions due to insufficient material supply. In the prior art, patent CN 221476010U discloses a bottle cap feeding device, including a multi-axis drive frame. The moving end of the multi-axis drive frame is fixedly connected to several suction components. Each suction component includes a suction cup seat. A suction cup cup is fixedly connected to the bottom edge of the suction cup seat. A guide hole is opened at the center of the suction cup seat, and a guide plate is slidably connected to the inner wall of the guide hole. The advantages of this invention are: the sealing head can press the center hole of the bottle cap tightly, and the device can be inserted to fix and move the bottle cap by negative pressure adsorption. However, during the adsorption process, additional positioning components are required to adjust the position of the bottle cap to ensure precise alignment with the suction cup, which takes extra time and reduces the production efficiency of plastic bottle caps. Moreover, negative pressure adsorption has certain limitations. For example, it may not be effective for bottle caps with irregular shapes or complex surfaces; some soft plastic bottle caps may be flattened under high vacuum, affecting subsequent operations and product quality. Therefore, we propose a feeding device for plastic bottle cap production. Utility Model Content

Detailed Implementation

[0014] 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.

[0015] Please see Figure 1-6 This embodiment provides a technical solution: a feeding device for producing plastic bottle caps, including a connecting seat 1, a mounting frame 4 at the lower end of the connecting seat 1, a protective cover 5 at the front end of the mounting frame 4, and a collecting mechanism 6. Collection mechanism 6 includes a rotating cylinder 61, a mounting plate 62, a drive rod 63, and a material-picking assembly 67. The rotating cylinder 61 is rotatably connected to the lower side of the front wall of the mounting frame 4. The mounting plate 62 is located on the rear side of the outer arc surface of the rotating cylinder 61 and is located inside the mounting frame 4. The drive rod 63 is located on the right side of the rear end of the mounting plate 62. The material-picking assembly 67 is located inside the mounting frame 4 and is driven by the drive rod 63. The collection mechanism 6 also includes a worm gear 64, a servo motor 65, and a worm 66. The worm gear 64 is located on the rotating cylinder 61. On the front side of the outer arc surface, a servo motor 65 is located on the left side of the upper end of the protective cover 5. A worm gear 66 is provided at the lower end of the output shaft of the servo motor 65, and a worm wheel 64 is meshed with the worm gear 66. The input end of the servo motor 65 is electrically connected to the output end of the controller 2. The material handling assembly 67 includes a mounting rod 671 and a material handling hopper 672. The mounting rod 671 is rotatably connected to the middle of the front wall of the protective cover 5 and the lower side of the rear wall of the mounting frame 4, respectively. The front mounting rod 671 is located inside the rotating cylinder 61. A hopper 672 is provided between the relatively inner ends of the mounting rod 671. A drive groove is provided on the right side of the front end of the hopper 672. The rear end of the drive rod 63 is located inside the drive groove. The output shaft of the servo motor 65 drives the worm gear 66 to rotate. During the rotation, the worm gear 66 drives the worm wheel 64 to rotate through a meshing connection. During the rotation, the worm wheel 64 drives the mounting plate 62 to rotate through the rotating cylinder 61. The mounting plate 62 drives the drive rod 63 to rotate around the rotating cylinder 61. At this time, the drive rod 63 will be driven by the drive... The inside of the trough both slides and rotates relative to the drive trough, causing the drive rod 63 to drive the feeding hopper 672 to rotate counterclockwise around the mounting rod 671. At this time, friction is generated between the inner wall of the feeding hopper 672 and the plastic bottle cap, causing the plastic bottle cap to rise along the inner wall of the feeding hopper 672 and enter the feeding hopper 672. This makes it less likely to damage the plastic bottle cap, and there is no need to adjust the position of the plastic bottle cap. It can also transport bottle caps with irregular shapes or complex surfaces, improving versatility and increasing the production efficiency of plastic bottle caps.

[0016] It also includes a controller 2, which is located outside the connector 1. The input terminal of the controller 2 is electrically connected to an external power supply and can regulate the electrical components inside the device.

[0017] Among them: a potentiometer 7 is set in the middle of the front end of the protective cover 5. The rear end of the probe of the potentiometer 7 is fixedly connected to the front end of the mounting rod 671 on the front side. The potentiometer 7 is bidirectionally electrically connected to the controller 2. When the mounting rod 671 rotates, it will also drive the probe of the potentiometer 7 to rotate. The probe will drive the sliding contact inside the potentiometer 7 to rotate. At this time, the position of the sliding contact on the resistive body changes. When the sliding contact moves on the resistive body, the resistance value between the sliding contact and the two fixed terminals will change. Then the potentiometer 7 detects the changed resistance value through its own internal detection element. Finally, the potentiometer 7 calculates the rotation angle of the hopper 672 by using the known relationship between the resistance value and the angle.

[0018] Wherein: an electric push rod 3 is provided in the middle of the lower end of the connecting seat 1. The lower end of the telescopic end of the electric push rod 3 is fixedly connected to the upper end of the mounting frame 4. The input end of the electric push rod 3 is electrically connected to the output end of the controller 2. Through the control of the controller 2, the electric push rod 3 starts to run. The telescopic end of the electric push rod 3 extends, thereby driving the hopper 672 to move downward through the mounting frame 4.

[0019] Wherein: A laser rangefinder 8 is provided on the front side of the lower end of the connecting base 1. The laser rangefinder 8 corresponds to the upper and lower positions of the mounting bracket 4. The laser rangefinder 8 is bidirectionally electrically connected to the controller 2. During use, the built-in light source of the laser rangefinder 8 emits a laser beam to the upper end of the mounting bracket 4. When the laser comes into contact with the upper end of the mounting bracket 4, it will be reflected. The laser rangefinder 8 then receives the reflected light. The laser rangefinder 8 calculates the distance between the upper end of the laser rangefinder 8 and the upper end of the mounting bracket 4 by measuring the round-trip time (TOF) or phase difference of the laser.

[0020] The working principle of the feeding device for plastic bottle cap production provided by this utility model is as follows: Before use, connect the connecting seat 1 to the external mobile device. Then, the external mobile device moves the feeding device for plastic bottle cap production to the upper side of the storage box containing plastic bottle caps. Subsequently, measure the distance between the lower end of the feeding hopper 672 and the uppermost layer of plastic bottle caps in the storage box (e.g., denoted as a). Then, determine the insertion depth of the feeding hopper 672 according to the size of the plastic bottle caps. (For small plastic bottle caps, the insertion depth is generally about 10-15 mm, because small bottle caps are small in size and require a shallow insertion depth to ensure effective contact with the plastic bottle caps; for medium-sized plastic bottle caps, the insertion depth is usually 15-25 mm.) For medium-sized bottle caps, a moderate insertion depth is required to ensure stable and efficient material retrieval. For large plastic bottle caps, an insertion depth of 25-40 mm may be needed (due to their larger size, a deeper insertion depth is required to ensure sufficient cap retrieval). The insertion depth is then set as b. Subsequently, a laser rangefinder 8 is used to measure the distance between its lower end and the upper end of the mounting bracket 4. During use, the laser rangefinder 8 emits a laser beam to the upper end of the mounting bracket 4. The laser beam is reflected upon contact with the upper end of the mounting bracket 4, and the laser rangefinder 8 receives the reflected light. By measuring the round-trip time (TOF) or phase difference of the laser beam, the laser rangefinder 8 calculates the distance between the lower end and the upper end of the mounting bracket 4. The distance between the upper end of the laser rangefinder 8 and the upper end of the mounting bracket 4 is set as c. Then, the laser rangefinder 8 transmits the detected information to the controller 2 through its built-in data transmission module. The controller 2 receives the detected data through its built-in serial communication port. Then, the distance between the upper end of the laser rangefinder 8 and the upper end of the mounting bracket 4 is added to the distance between the lower end of the hopper 672 and the uppermost plastic bottle cap in the storage box, and the required insertion depth of the hopper 672. This gives the distance between the upper end of the laser rangefinder 8 and the upper end of the mounting bracket 4 when the hopper 672 is inserted into the designated position (set as d, d=a+b+c). Then, through the control of the controller 2, the electric push rod 3 starts to operate, and the telescopic end of the electric push rod 3 extends... The electric push rod 3 extends, causing the hopper 672 to move downwards via the mounting bracket 4. When the distance between the upper end of the laser rangefinder 8 and the upper end of the mounting bracket 4 is equal to d, it indicates that the hopper 672 has been inserted to the specified depth (the lower edge of the hopper 672 is an arc-shaped edge, which reduces friction between the hopper 672 and the plastic bottle cap, making it less likely to damage the plastic bottle cap during insertion). Then, through the control of the controller 2, the electric push rod 3 stops running, and the servo motor 65 starts running. The output shaft of the servo motor 65 drives the worm gear 66 to rotate. During the rotation, the worm gear 66 drives the worm wheel 64 to rotate through the meshing connection. During the rotation, the worm wheel 64 drives the mounting plate 62 to rotate through the rotating cylinder 61.Mounting plate 62 drives drive rod 63 to rotate around rotating cylinder 61. During this time, drive rod 63 slides inside drive groove and rotates relative to drive groove, causing drive rod 63 to drive hopper 672 to rotate counterclockwise around mounting rod 671. Friction is generated between the inner wall of hopper 672 and plastic bottle cap, causing the plastic bottle cap to rise along the inner wall of hopper 672 and enter hopper 672. During rotation, mounting rod 671 also drives the probe of potentiometer 7 to rotate, which in turn drives the sliding contact inside potentiometer 7 to rotate. This changes the position of the sliding contact on the resistive element. When the resistive element moves, the resistance between the sliding contact and the two fixed terminals changes. Potentiometer 7 detects this change in resistance using its internal sensing element. Finally, potentiometer 7 calculates the rotation angle of the hopper 672 (typically between 90° and 180°) based on the known relationship between resistance and angle. Potentiometer 7 then transmits the detected information to controller 2 via its built-in data transmission module. Controller 2 receives the detected data through its built-in serial communication port. When the specified angle is reached, controller 2 controls the servo motor 65 to stop and the electric push rod 3 to start moving. The telescopic end extends, causing the electric push rod 3 to drive the hopper 672 upward via the mounting bracket 4. The upward movement distance is equal to the downward movement distance. After the hopper 672 returns to its original position, the external mobile device moves the hopper 672 containing the plastic bottle caps. Once the mobile device moves the hopper 672 to the upper side of the production line, the electric push rod 3 stops operating under the control of the controller 2, and the servo motor 65 starts operating. The output shaft of the servo motor 65 drives the worm gear 66 to rotate. During the rotation, the worm gear 66 drives the worm wheel 64 to rotate through a meshing connection. During the process, the rotating cylinder 61 drives the mounting plate 62 to rotate, which in turn drives the drive rod 63 to rotate around the rotating cylinder 61. At this time, the drive rod 63 slides inside the drive groove and rotates relative to it, causing the drive rod 63 to drive the feeding hopper 672 to rotate clockwise around the mounting rod 671. As the feeding hopper 672 rotates, its opening gradually faces downwards, and the plastic bottle caps flow out from the opening, finally falling onto the production line. This completes the feeding of the plastic bottle caps, which are then sorted by the internal processing equipment (vibrating plate) of the production line.

[0021] It is worth noting that the controller 2 disclosed in the above embodiments can be AT89C51, the servo motor 65 can be 5IK200A-AF, the potentiometer 7 can be 3590S-2-502L, and the laser rangefinder 8 can be HMLDM-UD100A. The controller 2 controls the operation of the servo motor 65, potentiometer 7 and potentiometer 8 using methods commonly used in the prior art.
