Description

Technical Field

[0001] This utility model relates to the field of plastic shell production and processing technology, specifically to an automatic feeding device for plastic shells. Background Technology

[0002] Plastic casings refer to shell-like components made of plastic materials through processes such as injection molding and compression. They are used to enclose and protect internal parts or serve as the external structure of a product. These casings typically have a certain shape and structural strength and are widely used in various electronic products, home appliances, medical devices, automotive parts, etc., such as mobile phone casings, electrical control panel casings, and instrument protective cases. Their production and processing involves multiple steps, including material loading, positioning, assembly, and printing.

[0003] A prior art example, CN221739079U, discloses a feeding device for plastic lamp housings. This device includes a conveyor frame and a conveyor belt inclined at a certain angle, mounted on the conveyor frame. A drive motor is mounted on the conveyor frame. Multiple anti-slip ridges are provided on the upper surface of the conveyor belt, each ridge fitted with a rubber sleeve. A feeding hopper is provided around the outer perimeter of the conveyor belt. The feeding hopper includes side plates vertically mounted on both sides of the conveyor belt and a rear side plate vertically mounted on the conveyor belt to connect the two side plates. Inclined guide plates extending outwards are formed at the free ends above the two side plates. When a lamp housing is placed into the feeding hopper, it slides down the inclined guide plate, side plates, and rear side plate onto the conveyor belt. This invention utilizes a drive motor to drive the conveyor belt for feeding, and the anti-slip ridges on the conveyor belt enable automatic feeding even at large angles. Furthermore, the rubber sleeves on the anti-slip ridges effectively prevent scratches on the lamp housings.

[0004] Existing plastic lamp housing conveying devices can only achieve tilted conveying and scratch prevention functions, lacking a precise positioning mechanism for the plastic shells. When the plastic shells are conveyed to the processing station, they cannot be automatically centered or fixed by mechanical structure. Vibration and offset during the conveying process can easily lead to positional deviations in subsequent processing (such as drilling and printing), affecting product consistency. In addition, the anti-slip ridges of the conveyor belt have poor adaptability to plastic shells of different sizes and shapes. When handling irregularly shaped shells, jamming and stacking are prone to occur, requiring frequent manual intervention, which is difficult to meet the needs of efficient automated production. Therefore, we propose an automatic feeding device for plastic shells. Utility Model Content

[0005] One of the technical problems this application aims to solve is: by integrating precise positioning, it addresses the issues of insufficient positioning accuracy and poor adaptability of existing devices. To address the aforementioned technical problems, this application provides an automatic plastic shell feeding device, including a conveyor table, a vibrating plate on one side of the conveyor table, a conveyor belt in the middle of the inner side of the conveyor table, and a positioning element between the two side walls of the top of the conveyor table. The positioning element cooperates with the conveyor table and the vibrating plate to position the object being fed, thereby ensuring feeding efficiency.

[0006] Preferably, the positioning component includes a positioning frame disposed on the outer wall of the conveyor table. A rotating platform is rotatably connected to the top center of the positioning frame. Two evenly distributed connecting rods are rotatably connected to the top of the rotating platform. A slider is rotatably connected to the end of the connecting rod away from the rotating platform. Sliding grooves are provided on both sides of the top of the positioning frame. The slider is slidably connected to the sliding grooves. A second motor is disposed on the top inner side of the positioning frame. The output end of the second motor is fixedly connected to the bottom of the rotating platform. A positioning plate is disposed at the bottom of the slider.

[0007] Preferably, the positioning plate has a plurality of evenly distributed rubber pads on the opposite side.

[0008] Preferably, the connecting rod is made of high-strength steel.

[0009] Preferably, an extension plate is provided on one side of the positioning frame, and a reciprocating lead screw is horizontally installed inside the extension plate. A fixing rod is horizontally installed on the side of the extension plate away from the reciprocating lead screw. A motor is installed on the outer wall of one side of the extension plate. The output end of the motor is fixedly connected to one end of the reciprocating lead screw. A reciprocating slide is threadedly connected to the middle of the reciprocating lead screw. The reciprocating slide is slidably connected to the fixing rod. A scraper is provided at the bottom of the reciprocating slide.

[0010] Preferably, chip removal ports are provided on both sides of the conveyor.

[0011] Preferably, the height of the chip discharge slot is lower than the height of the conveyor belt.

[0012] This utility model has at least the following beneficial effects: 1. Through the synergistic effect of the positioning components, the second motor drives the rotary table to rotate, which in turn drives the connecting rod to push the slider to slide along the slide groove, so that the positioning plates on both sides move synchronously in opposite directions. This can adapt to plastic shells of different sizes and shapes, achieve automatic centering and fixing, solve the problem of processing position deviation caused by the lack of a precise positioning mechanism in existing devices, ensure the accuracy of subsequent drilling, printing and other processes, and improve product consistency.

[0013] 2. The rubber pads on the inside of the positioning plate increase friction to prevent the plastic shell from sliding during positioning and also prevent the shell surface from being scratched. The high-strength steel connecting rods ensure the stability and durability of the positioning structure, which can cope with shells of different weights for a long time. At the same time, compared with traditional anti-slip ridges, this positioning structure is more adaptable to irregularly shaped shells, reduces material jamming and stacking, reduces the frequency of manual intervention, and meets the needs of efficient automated production.

[0016] 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.

[0017] Example 1 Please see Figures 1-5 This utility model provides a technical solution: An automatic feeding device for plastic shells includes a conveyor table 1, a vibrating plate 2 on one side of the conveyor table 1, a conveyor belt 18 in the middle of the inner side of the conveyor table 1, and a positioning member 11 between the two side walls of the top of the conveyor table 1. The positioning member 11 cooperates with the conveyor table 1 and the vibrating plate 2 to position the object being fed, thereby ensuring feeding efficiency.

[0018] Furthermore, the positioning component 11 includes a positioning frame 10 disposed on the outer wall of the conveyor table 1. A rotating table 9 is rotatably connected to the top center of the positioning frame 10. Two evenly distributed connecting rods 8 are rotatably connected to the top of the rotating table 9. A slider 7 is rotatably connected to the end of the connecting rod 8 away from the rotating table 9. Sliding grooves 6 are provided on both sides of the top of the positioning frame 10. The slider 7 is slidably connected to the sliding grooves 6. A second motor 16 is disposed on the top inner side of the positioning frame 10. The output end of the second motor 16 is fixedly connected to the bottom of the rotating table 9. A positioning plate 17 is disposed at the bottom of the slider 7.

[0019] Furthermore, a plurality of evenly distributed rubber pads 19 are provided on the opposite side of the positioning plate 17.

[0020] Furthermore, the connecting rod 8 is made of high-strength steel.

[0021] In use, the vibratory feeder 2 uses high-frequency vibration to arrange the stacked plastic shells in a preset orientation, such as uniform orientation and flat surface facing down, and then pushes them one by one to the starting end of the conveyor belt 18 inside the conveyor table 1. The conveyor belt 18 operates continuously under the action of the drive mechanism (not shown), conveying the plastic shells towards the positioning station. When the plastic shell is conveyed by the conveyor belt 18 to the positioner 11, the motor 16 starts, and its output end drives the rotary table 9 to rotate in the middle of the top side of the positioning frame 10. When the rotary table 9 rotates, the two high-strength steel connecting rods 8 at its top pull or push the slider 7 synchronously, so that the slider 7 slides in opposite directions along the slide groove 6 at the top of the positioning frame 10. The positioning plate 17 at the bottom of the slider 7 moves synchronously with the slider 7. When moving in opposite directions, the rubber pad 19 on the inner side of the positioning plate 17 fits against both sides of the plastic shell, achieving automatic centering and fixation. After positioning is completed, the motor 16 reverses, the positioning plate 17 resets, and the shell continues to be conveyed to the next process by the conveyor belt 18.

[0022] Example 2 Please see Figure 2 - Figure 3 This utility model provides a technical solution: an extension plate 5 is provided on one side of the positioning frame 10, a reciprocating screw 13 is horizontally installed inside the extension plate 5, a fixing rod 14 is horizontally installed on the side of the extension plate 5 away from the reciprocating screw 13, a motor 4 is installed on the outer wall of one side of the extension plate 5, the output end of the motor 4 is fixedly connected to one end of the reciprocating screw 13, a reciprocating slide bar 15 is threadedly connected to the middle of the reciprocating screw 13, the reciprocating slide bar 15 is slidably connected to the fixing rod 14, and a scraper 12 is provided at the bottom of the reciprocating slide bar 15.

[0023] Furthermore, chip discharge ports 3 are provided on both sides of the conveyor table 1.

[0024] Furthermore, the height of the chip discharge port 3 is lower than the height of the conveyor belt 18.

[0025] Unlike Embodiment 1, during the outer shell conveying process, the motor 4 on one side of the extension plate 5 drives the reciprocating screw 13 to rotate in both directions, causing the reciprocating slide 15, which is threaded to the middle of the reciprocating screw 13, to move laterally along the fixed rod 14. The scraper 12 at the bottom of the reciprocating slide 15 moves synchronously with it to clean the dust, debris and impurities on the surface of the conveyor belt 18. The impurities pushed by the scraper 12 move along the surface of the conveyor belt 18 to the chip discharge ports 3 on both sides of the conveyor table 1. Since the height of the chip discharge port 3 is lower than that of the conveyor belt 18, the impurities fall naturally and are discharged from the chip discharge port 3, avoiding accumulation and contamination of the outer shell or affecting the conveying efficiency. If dust, debris and other impurities remain on the surface of the conveyor belt 18, the plastic outer shell may experience slight displacement due to uneven force during the conveying process, or tilt in position due to impurities being raised when clamped by the positioning plate 17. The scraper 12 cleans impurities through reciprocating motion and discharges them through the chip outlet 3, ensuring that the surface of the conveyor belt 18 is flat and clean, so that the outer shell is in a stable initial position when it reaches the positioning member 11, providing a basis for the precise clamping of the positioning plate 17 and reducing positioning deviations caused by impurities.
