Description

Technical Field

[0001] This utility model relates to the field of rubber stopper feeding technology, specifically a rubber stopper feeding mechanism. Background Technology

[0002] Rubber stoppers, especially coated rubber stoppers, are sealing container components made of rubber, silicone, or other polymeric materials. They are widely used in food processing, pharmaceutical manufacturing, and cosmetics manufacturing due to their high mechanical strength, good biocompatibility, resistance to chemical corrosion, excellent sealing performance, and oxidation resistance. For example, in pharmaceutical manufacturing, rubber stoppers, as representative pharmaceutical stoppers, are used to package antibiotics, injections, eye drops, oral solutions, and nasal sprays, and are crucial for the long-term stability of drugs.

[0003] In traditional rubber stopper production, the feeding process often relies on manual operation. Operators need to manually place the rubber stoppers one by one into the corresponding positions on the mold or production equipment. This method is not only inefficient and difficult to meet the needs of large-scale production, but also prone to problems such as inaccurate feeding and rubber stopper damage due to human factors. In view of this, a rubber stopper feeding mechanism is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a rubber stopper feeding mechanism that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a rubber stopper feeding mechanism, comprising a support base and a vibrating hopper. The support base is equipped with a first driving mechanism and a second driving mechanism. A connecting assembly is provided on the upper side of the support base. A guide trough is fixedly connected to the outer wall of the vibrating hopper. The second driving mechanism includes:

[0006] Motor 2 is fixedly connected to the lower side of the support base, and a lead screw is fixedly connected to the output shaft of Motor 2;

[0007] A threaded seat is threadedly connected to a lead screw, and a lifting shaft is fixedly connected to the upper side of the threaded seat;

[0008] The mounting block is fixed to the top of the lifting shaft, and a mounting plate is fixedly connected to the outer wall of the mounting block, and a fixing pressure plate is fixedly installed on the mounting plate.

[0009] The ejector pin is fixed to the fixed pressure plate. The output shaft of the second motor rotates, which drives the lead screw to rotate. Under the limiting action of the lifting shaft, the threaded seat and the lifting shaft rise, which drives the mounting block and the fixed pressure plate to rise, and then drives the ejector pin to rise, so as to facilitate the subsequent ejection of the bottle stopper.

[0010] Preferably, the drive mechanism includes a motor, which is fixedly connected to the lower side of the support base. A rotating shaft is fixedly connected to the output shaft of the motor, and a swing arm is fixedly connected to the top of the rotating shaft. A deflection cam bearing is fixedly connected to the end of the swing arm away from the rotating shaft. The rotating shaft is rotated by the rotation of the output shaft of the motor, which in turn drives the deflection cam bearing to move.

[0011] Preferably, the connecting assembly includes a side plate, a fixed shaft is fixedly connected to the surface of the side plate, a fixed seat is fixedly connected to the fixed shaft, a guide rod is fixedly connected to the upper side of the mounting plate, and a plug plate is fixedly connected to the top of the guide rod.

[0012] Preferably, the top of the connecting plate is detachably connected to a disassembly knob, and the fixed shaft passes through the movable plate and is slidably connected to the movable plate. During the movement of the deflection cam, the deflection cam squeezes the movable plate to move, causing the movable plate to slide on the fixed shaft.

[0013] Preferably, the top of the lead screw is rotatably connected to the lower side of the fixed seat.

[0014] Preferably, the lifting shaft passes through the fixed seat and is slidably connected to the fixed seat.

[0015] This utility model provides a rubber stopper feeding mechanism. It has the following beneficial effects:

[0016] (1) The rubber stopper feeding mechanism works in concert with the first and second drive mechanisms. The first motor drives the deflection cam bearing to move, which in turn drives the movable plate to move, so that the rubber stopper can smoothly enter the groove of the receiving plate. The second motor, through the cooperation of the lead screw and the threaded seat, realizes the lifting and lowering of the ejector pin, and ejects the bottle stopper out of the groove of the receiving plate. This realizes the automatic feeding and ejection of the rubber stopper. The entire feeding process does not require manual intervention, which greatly improves production efficiency.

[0017] (2) The rubber stopper feeding mechanism is connected to the ejector pin by a disassembly knob through the stopper plate. This design not only facilitates the sterilization of the stopper plate and ejector pin to ensure the hygiene and safety of the production process, but also facilitates the cleaning and maintenance of the entire mechanism, extending the service life of the equipment. In addition, the design of the guide trough plate also facilitates the smooth introduction and export of rubber stoppers, reducing the occurrence of blockages and malfunctions.

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.

[0027] Please see Figures 1-4 This utility model proposes a rubber stopper feeding mechanism, including a support base 1 and a vibrating hopper 5.

A guide trough plate 6 is fixedly connected to the outer wall of the vibrating hopper 5. By using the vibrating hopper 5, the rubber stopper enters the guide trough of the guide trough plate 6.

[0028] In this embodiment of the utility model, the drive mechanism 2 includes a motor 21, which is fixedly connected to the lower side of the support base 1. A rotating shaft 22 is fixedly connected to the output shaft of the motor 21. A swing arm 23 is fixedly connected to the top of the rotating shaft 22. A deflection cam bearing 24 is fixedly connected to the end of the swing arm 23 away from the rotating shaft 22. The connecting assembly 4 includes a side plate 41, a fixed shaft 42 is fixedly connected to the surface of the side plate 41, a fixed base 43 is fixedly connected to the fixed shaft 42, and a guide rod 44 is fixedly connected to the upper side of the mounting plate 36. A plug plate 45 is fixedly connected to the top of 44. A disassembly knob 46 is detachably connected to the top of the plug plate 45. The fixed shaft 42 passes through the movable plate 47 and is slidably connected to the movable plate 47. By starting the motor 21, the output shaft of the motor 21 drives the rotating shaft 22 to rotate, which in turn drives the swing arm 23 to rotate, causing the deflection cam bearing 24 to move. The deflection cam bearing 24 presses the movable plate 47 to move. The movable plate 47 slides on the fixed shaft 42. After the movable plate 47 moves to the set position, the rubber plug can enter the groove on the plug plate 45.

[0029] Furthermore, to enable automatic plugging operation, the drive mechanism 2 3 specifically includes a motor 2 31, a threaded seat 33, a mounting block 35, and a ejector pin 38. The motor 2 31 is fixedly connected to the lower side of the support base 1. A lead screw 32 is fixedly connected to the output shaft of the motor 2 31. The threaded seat 33 is threadedly connected to the lead screw 32. A lifting shaft 34 is fixedly connected to the upper side of the threaded seat 33. The mounting block 35 is fixed to the top of the lifting shaft 34. A mounting plate 36 is fixedly connected to the outer wall of the mounting block 35. A fixing pressure plate 37 is fixedly mounted on the mounting plate 36. The ejector pin 38 is connected to the fixing pressure plate 37. With the screw 32 fixed, the top of the screw 32 is rotatably connected to the lower side of the fixed seat 43. The lifting shaft 34 passes through the fixed seat 43 and is slidably connected to the fixed seat 43. By starting the motor 31, the output shaft of the motor 31 rotates, driving the screw 32 to rotate. Then, under the limiting action of the lifting shaft 34, the threaded seat 33 and the lifting shaft 34 rise, driving the mounting block 35 and the fixed pressure plate 37 to rise, which in turn drives the ejector pin 38 to rise, pushing the bottle stopper out of the groove on the stopper receiving plate 45. This realizes the automatic feeding and ejection operation of the rubber stopper. The entire feeding process does not require manual intervention, which greatly improves production efficiency.

[0030] Alternatively, the plug plate 45 and the ejector pin 38 can be sterilized by rotating the disassembly knob 46.

Those skilled in the art should select, install, and debug the circuits according to their needs to ensure that all electrical appliances function properly. All components are general standard parts or parts known to those skilled in the art, and their structures and principles can be obtained by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are imposed here.

[0032] In use, the vibrating hopper 5 is used to guide the rubber stopper into the guide groove of the guide plate 6. Then, motor 21 is started. The output shaft of motor 21 drives the rotating shaft 22 to rotate, which in turn drives the swing arm 23 to rotate, causing the deflection cam bearing 24 to move. The deflection cam bearing 24 presses the movable plate 47 to move. The movable plate 47 slides on the fixed shaft 42. After the movable plate 47 moves to the set position, the rubber stopper can enter the groove on the stopper receiving plate 45. Then, the output shaft of motor 21 is started to reverse and reset, so that the rubber stopper in the guide plate 6 is blocked by the stopper receiving plate 45 again. Then, motor 31 is started. The output shaft of motor 31 rotates, which drives the lead screw 32 to rotate. Then, under the limiting action of the lifting shaft 34, the threaded seat 33 and the lifting shaft 34 rise, which drives the mounting block 35 and the fixed pressure plate 37 to rise, which in turn drives the ejector pin 38 to rise, pushing the bottle stopper out of the groove on the stopper receiving plate 45.
