Technical Field

[0001] This utility model belongs to the field of pharmaceutical aluminum-plastic cap pressing technology, and in particular relates to a pressing and riveting mechanism for aluminum-plastic caps of oral liquid medicine bottles. Background Technology

[0002] Aluminum-plastic caps are a widely used packaging material in the food, pharmaceutical, and cosmetic industries. Composed of aluminum foil and plastic film, they offer excellent sealing, moisture resistance, oxidation resistance, and corrosion resistance. A pressing device is required when sealing aluminum-plastic caps to glass bottle necks. Existing pressing and riveting devices for oral liquid medicine bottle aluminum-plastic caps are typically located on the upper part of the equipment frame, performing the pressing and riveting operation by pressing downwards. This requires a certain amount of space for the pressing and riveting mechanism. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a riveting mechanism for the aluminum-plastic cap of oral liquid medicine bottles with the drive mechanism integrated inside the equipment frame, so as to reduce the space occupancy rate.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: an aluminum-plastic cap riveting mechanism for oral liquid medicine bottles, comprising a capping head, a first connecting rod, a first bracket, a second bracket, a third bracket, a bushing, a driven sprocket, a rotating shaft, a turntable, a support base, and a second connecting rod;

[0005] The capping head is fixedly installed on the top of the first connecting rod. The first bracket, the second bracket, and the third bracket are all fixedly installed on the equipment frame. The first ball bearing is fixedly installed inside the first bracket and the second bracket. The two ends of the rotating shaft are fixedly installed in the rotating body of the first ball bearing. The driven sprocket and the turntable are fixedly sleeved on the rotating shaft.

[0006] The bushing is fixedly installed on the support base, the support base is fixedly installed on the bottom of the equipment frame, the rotating shaft is rotatably installed in the bushing, a guide rod is fixedly installed on the upper part of the bushing, the lower end of the first connecting rod is slidably installed in the guide rod, and the second connecting rod is vertically fixedly installed on the lower part of the first connecting rod.

[0007] The third bracket has an elongated hole in the vertical direction, and the turntable has a cam groove. The two ends of the second connecting rod are slidably installed in the cam groove and the elongated hole, respectively.

[0008] Furthermore, a second ball bearing and a third ball bearing are fixedly installed at both ends of the second connecting rod, with the second ball bearing slidably installed in the cam groove and the third ball bearing slidably installed in the elongated hole.

[0009] Furthermore, a positioning rod is provided at the lower part of the bushing, and the positioning rod is welded and fixedly installed in the support base.

[0010] Furthermore, the support base is fixedly installed with a connecting seat, which is screwed and fixedly installed at the bottom of the equipment frame.

[0011] Compared with the prior art, the advantages of this utility model are: the riveting mechanism integrates its drive mechanism inside the equipment frame, which reduces the height space occupied during installation. The enclosed structure of the equipment frame can protect the drive mechanism of the riveting mechanism, prevent it from sticking to oil and dust, and extend the service and maintenance cycle of the riveting mechanism.

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] Figure 1 This is a perspective view of the front of this utility model.

[0014] Figure 2 This is a perspective view of the rear of this utility model. Detailed Implementation

[0015] The present invention will now be described in detail with reference to specific embodiments:

[0016] like Figure 1 and Figure 2 The above describes a riveting mechanism for aluminum-plastic caps on oral liquid medicine bottles, which includes a capping head 1, a first connecting rod 2, a first bracket 3, a second bracket 4, a third bracket 5, a bushing 6, a driven sprocket 61, a rotating shaft 62, a turntable 7, a support base 8, and a second connecting rod 9.

[0017] The capping head 1 is fixedly installed on the top of the first connecting rod 2. The first bracket 3, the second bracket 4, and the third bracket 5 are all fixedly installed on the equipment frame. The first ball bearing is fixedly installed inside the first bracket 3 and the second bracket 4. That is, the cage of the first ball bearing is fixedly installed inside the first bracket 3 and the second bracket 4. The two ends of the rotating shaft 62 are fixedly installed in the rotating body of the first ball bearing. The driven sprocket 61 and the turntable 7 are both fixedly sleeved on the rotating shaft 62.

[0018] The bushing 6 is fixedly installed on the support base 8, the support base 8 is fixedly installed on the bottom of the equipment frame, the rotating shaft 62 is rotatably installed in the bushing 6, a guide rod is fixedly installed on the upper part of the bushing 6, the lower end of the first connecting rod 2 is slidably installed in the guide rod, and the second connecting rod 9 is vertically fixedly installed on the lower part of the first connecting rod 2.

[0019] The third bracket 5 is provided with an elongated hole 51 in the vertical direction, and the turntable 7 is provided with a cam groove 71. The two ends of the second connecting rod 9 are respectively slidably installed in the cam groove 71 and the elongated hole 51.

[0020] The second connecting rod 9 has a second ball bearing 91 and a third ball bearing 92 fixedly installed at both ends. The rotating parts of the second ball bearing 91 and the third ball bearing 92 are fixedly connected to both ends of the second connecting rod 9. The second ball bearing 91 is slidably installed in the cam groove 71, and the third ball bearing 92 is slidably installed in the elongated hole 51. The rolling action of the second ball bearing 91 and the third ball bearing 92 can reduce friction and extend the service life of the second connecting rod 9, the turntable 7, and the third bracket 5.

[0021] The bushing 6 is provided with a positioning rod at its lower part, and the support base 8 is provided with a positioning hole at its top that cooperates with the positioning rod. After the positioning rod is pre-fixed by inserting it into the positioning hole, the positioning rod is then welded to the support base 8 for fixation, which can improve the installation position accuracy of the bushing 6 and the strength of the installation structure.

[0022] The support base 8 is fixedly installed with a connecting base 81, which is screwed to the bottom of the equipment frame to facilitate the connection and fixation between the support base 8 and the bottom of the equipment frame. At the same time, the connecting hole on the connecting base 81 is designed as an oblong hole structure, which allows for adjustment of the installation position of the assembly of the connecting base 81 and the support base 8.

[0023] A drive motor is installed inside the equipment frame. A drive sprocket is mounted on the output shaft of the drive motor. The drive sprocket and the driven sprocket 61 are connected by a chain drive. When the aluminum-plastic cap of the oral liquid medicine bottle is pressed and riveted, the drive motor drives the combination of the drive sprocket, the rotating shaft 62, and the turntable 7 to rotate. The cam groove 71 of the turntable 7 drives the combination of the second connecting rod 9, the first connecting rod 2, and the capping head 1 to move up and down. The lower end of the first connecting rod 2 cooperates with the guide rod to provide guidance for the up and down movement. The third ball bearing 92 at one end of the second connecting rod 9 cooperates with the elongated hole 51 of the third bracket 5 to also provide guidance for the up and down movement. The capping head 1 contacts the aluminum-plastic cap on the oral liquid medicine bottle and performs the capping and riveting operation. The cam groove 71 of the turntable 7 drives the capping head 1 to move up and down reciprocally. Compared with the linear electric push rod or linear hydraulic cylinder drive, the capping head 1 has the advantage of high stroke accuracy.
