Description

Technical Field

[0001] This utility model relates to the field of pneumatic capping technology, and in particular to a pneumatic capping and screwing mechanism. Background Technology

[0002] The stability of the material falling process directly affects production efficiency, product quality, and equipment safety. Traditional material falling devices often suffer from unevenness when bottle caps land on the bottle body due to impact vibration and positioning deviations, which may cause machine jamming and affect subsequent capping operations, becoming a long-standing pain point in the manufacturing industry. If the capping torque is too high, it will damage the bottle cap; if the torque is too low, the sealing effect cannot be guaranteed.

[0003] To address this issue, we propose a pneumatic capping and screwing mechanism. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pneumatic capping and screwing mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pneumatic capping and screwing mechanism includes a belt conveyor on which bottles are conveyed. A capping mechanism and a screwing mechanism are sequentially installed on the side of the belt conveyor. The capping mechanism includes a fixed frame, a storage hopper is installed above the fixed frame, and a supporting base plate is provided below the storage hopper. A first cylinder is installed above one end of the supporting base plate, and a material dropping component is installed at the other end of the supporting base plate. A connecting block is fixedly connected to the inner wall of the fixed frame, and a second cylinder is installed at the outer end of the connecting block. Multiple bottle caps are stacked inside the storage hopper.

[0006] Preferably, the storage hopper is cylindrical and is mounted above the supporting base plate through the connecting block.

[0007] Preferably, the end of the connecting block is bolted to a fixing plate, and the second cylinder is installed inside the fixing plate.

[0008] Preferably, the bottom end of the second cylinder is fitted with a rubber head, and the bottom cross-section of the rubber head is shaped like a frustum.

[0009] Preferably, the material feeding assembly includes a material feeding bin, which is installed below the other end of the supporting base plate, and multiple universal ball bearings are installed at equal intervals on the inner wall of the material feeding bin.

[0010] Preferably, the capping mechanism includes a dual-axis guide post, a third cylinder is installed inside the dual-axis guide post, and a mounting plate is bolted to the surface of the third cylinder. A pneumatic motor is installed above the mounting plate, and a capping cover is connected to the bottom of the pneumatic motor via a spring. The inner wall of the capping cover is provided with a silicone pad.

[0011] Preferably, two dual-axis guide pillars are symmetrically arranged, and both dual-axis guide pillars are cylindrical. A circular hole adapted to the dual-axis guide pillars is opened in the top of the third cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device utilizes universal ball bearings, leveraging their omnidirectional motion characteristics and low friction advantages, along with the rigid connection between the feeding hopper and the flange, to form a composite solution that balances buffering, positioning, and sealing. A second cylinder pneumatically delivers the caps, and by adjusting the bearing bolt depth of the universal ball bearing, elastic internal cavity adjustment is achieved. This ensures a tight fit between the bottle cap and the inner wall of the feeding hopper, guaranteeing that the cap falls horizontally onto the bottle body. This effectively solves the problem of uneven cap placement caused by errors in the bottle cap's outer diameter, ensuring a smooth cap placement effect. The caps land safely and stably on the bottle body, maintaining a horizontal position, thus completing the initial capping process.

[0013] 2. This device uses a pneumatic motor to screw on the cap, and a pressure control switch ensures that the screwing torque is controllable and reliable. It can stabilize the screwing torque, effectively avoid damage to the bottle cap and reduce wear on the inner cavity, improve packaging quality, and is widely applicable to tightening screw caps. It has a wide screwing range, is not limited by the bottle body, and is easy to operate. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 A pneumatic capping and screwing mechanism includes a belt conveyor 1, on the surface of which a bottle body 2 is conveyed. A capping mechanism 3 and a screwing mechanism 5 are sequentially installed on the side of the belt conveyor 1. Two extrusion cylinders are symmetrically installed on the surface of the belt conveyor 1 and below the capping mechanism 3 and the screwing mechanism 5 to facilitate clamping and limiting the bottle body 2. The capping mechanism 3 includes a fixing frame 31. A storage bin 32 is installed above the fixing frame 31. A supporting base plate 33 is provided below the storage bin 32. A first cylinder 34 is installed above one end of the supporting base plate 33. A material dropping component 4 is installed at the other end of the supporting base plate 33. A baffle is fixed above the end of the supporting base plate 33 near the material dropping component 4 to limit and block the bottle cap 6 pushed by the first cylinder 34. A connecting block 35 is fixedly connected to the inner wall of the fixing frame 31, and a second cylinder 36 is installed at the outer end of the connecting block 35. Multiple bottle caps 6 are stacked inside the storage bin 32.

[0018] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the storage bin 32 is set in a cylindrical shape. The storage bin 32 passes through the connecting block 35 and is installed above the supporting base plate 33. The cylindrical shape of the storage bin 32 facilitates the stacking of multiple bottle caps 6.

[0019] Furthermore, refer to Figure 2 It can be seen that the end of the connecting block 35 is fitted with a fixing plate by bolts, and the second cylinder 36 is installed inside the fixing plate. The fixing plate and the connecting block 35 can be disassembled and assembled by bolts, which can facilitate the disassembly and maintenance of the second cylinder 36.

[0020] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the bottom end of the second cylinder 36 is fitted with a rubber head, and the bottom cross-section of the rubber head is set as a frustum. The rubber head fitted at the bottom end of the second cylinder 36 can easily push the bottle cap 6 in the feeding assembly 4. At the same time, by adjusting the bearing bolt depth of the universal ball bearing 42, multiple universal ball bearings 42 can be conveniently positioned to limit different bottle caps 6.

[0021] Furthermore, refer to Figure 4 It can be seen that the material feeding assembly 4 includes a material feeding bin 41. The material feeding bin 41 is installed below the other end of the supporting base plate 33, and multiple universal ball bearings 42 are installed at equal intervals on the inner wall of the material feeding bin 41. The multiple universal ball bearings 42 installed at equal intervals on the inner wall of the material feeding bin 41 can conveniently limit the function of the bottle cap 6.

[0022] Furthermore, refer to Figure 1 and Figure 4 It can be seen that the capping mechanism 5 includes a dual-axis guide post 51, a third cylinder 52 is installed inside the dual-axis guide post 51, and a mounting plate 53 is bolted to the surface of the third cylinder 52. A pneumatic motor 54 is installed above the mounting plate 53. The mounting plate 53 can support the pneumatic motor 54. The capping cover 55 is connected to the bottom of the pneumatic motor 54 by a spring 57. A silicone inner pad 56 is provided on the inner wall of the capping cover 55. The silicone inner pad 56 increases the friction to ensure torque and will not damage the appearance of the cap 6.

[0023] Furthermore, refer to Figure 3 and Figure 4 It can be seen that there are two symmetrically arranged dual-axis guide posts 51, and both dual-axis guide posts 51 are cylindrical. The top of the third cylinder 52 has a round hole that matches the dual-axis guide post 51. By moving the top of the third cylinder 52, the third cylinder 52 can slide along the surface of the two dual-axis guide posts 51, which plays the role of limiting and guiding the third cylinder 52.

[0024] Working principle: When this utility model is in use, when the belt conveyor 1 is in use, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 The storage hopper 32 contains stacked bottle caps 6. Under gravity, the bottle caps 6 fall one by one onto the supporting base plate 33. The bottle caps on the supporting base plate 33 are pushed into the discharge hopper 41 by the first cylinder 34. Through the multiple universal ball bearings 42 installed in the discharge hopper 41, the bottle caps 6 are squeezed by the multiple universal ball bearings 42 and will not fall off naturally. Therefore, the end of the second cylinder 36 needs to be inserted to push out the bottle caps 6 and let them fall above the belt conveyor 1. On the conveyed bottle body 2, the bottle body 2 and the bottle cap 6 can be moved to the bottom of the capping cover 55 by the conveyor belt 1. At this time, the end of the third cylinder 52 retracts along the surface of the double-axis guide post 51, so that the mounting plate 53 drives the pneumatic motor 54 and the capping cover 55 to move down as a whole. The capping cover 55 drives the silicone inner pad 56 to be put on the bottle cap 6 to be capped. The pneumatic motor 54 can make the capping cover 55 and the silicone inner pad 56 tighten the bottle cap 6. The above is the complete working principle of this utility model.
