Description

Technical Field

[0001] This utility model relates to the field of bottle cap technology, specifically to a pressing device for assembling bottle caps and gaskets. Background Technology

[0002] To improve sealing, some bottle caps require internal gaskets. Most bottle cap gaskets are made of plastic. Currently, the installation of bottle cap gaskets can be automated, replacing manual labor and improving efficiency. Bottle cap gaskets need to be stacked in automated equipment. A robotic arm or similar structure picks up the bottom bottle cap gasket and presses it into the bottle cap for automatic feeding. As the stacked bottle cap gaskets are gradually consumed, the overall pressure exerted by the stacked gaskets on the bottom bottle cap gasket gradually decreases. When there are fewer stacked gaskets, the overall weight of the bottle cap gaskets may be insufficient to press down the bottom gasket for automatic feeding, resulting in the bottle cap gaskets not being picked up and affecting the efficiency of bottle cap processing.

[0003] Based on the above, Chinese patent document CN218200352U discloses a bottle cap gasket assembly device, including a mounting cabinet, a first conveyor belt, a bottle cap adsorption and flipping mechanism, a second conveyor belt, and a gasket adsorption and flipping mechanism. The first conveyor belt is arranged along the length of the mounting cabinet, and bottle caps are placed on the first conveyor belt. The bottle cap adsorption and flipping mechanism and the gasket adsorption and flipping mechanism are respectively installed at both ends of the top surface of the mounting cabinet along the length direction, located at the two ends of the first conveyor belt. A gasket is placed on the top of the gasket adsorption and flipping mechanism. The second conveyor belt is installed on the mounting cabinet along the width direction and is located below the gasket adsorption and flipping mechanism. The bottle cap adsorption and flipping mechanism is used to transfer bottle caps from the first conveyor belt to the second conveyor belt, and the gasket adsorption and flipping mechanism is used to transfer the top gasket to the second conveyor belt and assemble it with the corresponding bottle cap.

[0004] The aforementioned patent document discloses a device for assembling gaskets inside bottle caps. The gasket adsorption and flipping mechanism of this device uses a suction cup to adsorb the stacked gaskets through the upper through-hole, and then transfers the gaskets downwards and assembles them inside the bottle cap. However, when the suction cup adsorbs the gaskets, the gaskets need to apply a certain pressure to the suction cups to be adsorbed smoothly. When there are fewer stacked gaskets, the overall pressure of the gaskets may not be sufficient to adsorb the bottom gasket, causing the gasket adsorption and flipping mechanism to be unable to transfer the gaskets downwards and assemble them inside the bottle cap, thereby affecting the efficiency of bottle cap processing. Therefore, there is still room for improvement in this bottle cap gasket assembly device. Utility Model Content

[0005] To address the technical deficiencies in the background art, this utility model proposes a clamping device for assembling bottle caps and gaskets, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows: A pressing device for assembling bottle caps and gaskets includes a conveying mechanism, a gasket feeding mechanism, a gasket pressing mechanism, and a storage mechanism. The conveying mechanism has an input end and an output end at both ends along the conveying direction.

The bottom of the film feeding mechanism is provided with a transfer block, and the bottom of the transfer block is provided with two negative pressure suction cups, one of which is located above the material storage mechanism and the other is located above the conveying mechanism. The top of the transfer block is provided with a second driving structure that causes the transfer block to reciprocate in the up and down direction, and the top of the second driving structure is provided with a third driving structure that causes the second driving structure and the transfer block to rotate. The tableting mechanism has a tableting block at the bottom and a fourth driving structure at the top of the tableting block to make the tableting block reciprocate in the up-down direction.

[0006] As a further technical solution of this utility model, a feeding base plate is provided at the bottom of the inner side of the storage tank, and a fifth driving structure is provided at the bottom of the feeding base plate to make the feeding base plate reciprocate in the up and down direction. A first detection element is provided at the position of the inner side of the storage tank near the top.

[0007] As a further technical solution of this utility model, the conveying mechanism is in the shape of a ring structure and rotates along its own axis, and the outer edge of the conveying mechanism is provided with several conveying grooves.

[0010] As a further technical solution of this utility model, a gasket detection mechanism is provided above the conveying mechanism. The gasket detection mechanism is located between the tablet placement mechanism and the tablet pressing mechanism along the conveying direction of the conveying mechanism. A second detection element and an air blowing structure are provided at the bottom of the gasket detection mechanism.

[0011] As a further technical solution of this utility model, a third detection element facing the conveying mechanism is provided on one side of the tablet feeding mechanism, and a fourth detection element facing the conveying mechanism is provided on one side of the tablet pressing mechanism.

[0012] The beneficial effects of this utility model are as follows: This utility model discloses a device for assembling and pressing gaskets into the inside of bottle caps. A conveying mechanism sequentially transports bottle caps below a gasket placement mechanism and a gasket pressing mechanism. When the bottle cap is transported to the gasket placement mechanism, the mechanism rotates a transfer block to allow two negative pressure suction cups to alternately pick up and place the gasket. The gasket is then pressed into the inside of the bottle cap by the gasket pressing mechanism. Additionally, the gasket is automatically fed upwards from the bottom of a storage tank via a feeding base plate. The negative pressure suction cups press down and pick up the gasket from above. The bottom of the storage tank supports the gasket, ensuring that the negative pressure suction cups can smoothly pick up the gasket and place it smoothly inside each bottle cap, thus improving the processing efficiency of the bottle caps.

[0019] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0020] A pressing device for assembling bottle caps and gaskets includes a conveying mechanism 1, a gasket feeding mechanism 2, a gasket pressing mechanism 3, and a storage mechanism 4. The conveying mechanism 1 has an input end 11 and an output end 12 at both ends along the conveying direction. The gasket feeding mechanism 2 and the gasket pressing mechanism 3 are both located above the conveying mechanism 1 and are arranged sequentially along the conveying direction of the conveying mechanism 1. The material storage mechanism 4 is located below the film feeding mechanism 2. The top of the material storage mechanism 4 is provided with at least two material storage slots 41 with openings facing upwards, and the bottom of the material storage mechanism 4 is provided with a first driving structure 42 that causes the material storage slots 41 to exchange positions sequentially. The bottom of the film feeding mechanism 2 is provided with a transfer block 21, and the bottom of the transfer block 21 is provided with two negative pressure suction cups 22. One negative pressure suction cup 22 is located above the material storage mechanism 4 and the other negative pressure suction cup 22 is located above the conveying mechanism 1. The top of the transfer block 21 is provided with a second drive structure 23 that causes the transfer block 21 to reciprocate in the up and down direction. The top of the second drive structure 23 is provided with a third drive structure 24 that causes the second drive structure 23 and the transfer block 21 to rotate. The tablet compression mechanism 3 has a tablet compression block 31 at the bottom and a fourth drive structure 32 at the top of the tablet compression block 31 to make the tablet compression block 31 reciprocate in the up and down direction.

[0021] This utility model discloses a device for assembling and tightening a gasket into the inside of a bottle cap, see reference. Figure 1 , Figure 2The equipment mainly consists of a conveying mechanism 1, a tablet placement mechanism 2, a tablet pressing mechanism 3, and a storage mechanism 4. The conveying mechanism 1 is mainly used to convey the formed bottle caps. The bottle caps are conveyed inside the conveying mechanism 1 with their openings facing upwards. The bottle caps are conveyed sequentially along the direction of the tablet placement mechanism 2 and the tablet pressing mechanism 3. The storage mechanism 4 temporarily stores the gaskets through the storage trough 41. When the conveying mechanism 1 conveys the bottle caps to match the tablet placement mechanism 2, the tablet placement mechanism 2 transfers the gaskets from the storage mechanism 4 and places them inside the bottle caps. Then, the conveying mechanism 1 continues to convey the bottle caps with the gaskets to match the tablet pressing mechanism 3. The tablet pressing mechanism 3 presses the gaskets tightly inside the bottle caps, thereby completing the assembly of the gaskets and the bottle caps. It should be noted that the conveying mechanism 1 has a circular structure and rotates along its own axis. The conveying mechanism 1 can be driven by a servo motor to rotate. An annular pulley 17 is provided at the bottom of the conveying mechanism 1, and a belt 18 is wound around the outside of the annular pulley 17. The belt 18 is driven to rotate by the servo motor and cooperates with the annular pulley 17, thereby driving the conveying mechanism 1 to rotate. Several conveying grooves 13 are provided on the outer edge of the conveying mechanism 1; the input end 11 is provided with a feed track 14 that matches the conveying grooves 13 and extends outward, and the output end 12 is provided with a feed track 14 that matches the conveying grooves 13 and extends outward. The discharge track 15 has a discharge guide rod 16 at the top that extends inclined toward the center of the conveying mechanism 1; the feeding track 14 guides the bottle caps into the conveying trough 13 at the edge of the conveying mechanism 1. As the conveying mechanism 1 rotates, the conveying mechanism 1 causes the bottle caps in the conveying trough 13 to move in a circle along the edge of the conveying mechanism 1. During the movement, the bottle caps will pass through the tablet feeding mechanism 2 and the tablet pressing mechanism 3 in sequence and reach the output end 12. The bottle caps are guided into the discharge track 15 by the discharge guide rod 16. The bottle caps that have completed the gasket assembly are guided to the next process through the discharge track 15. Furthermore, referring to Figure 1 , Figure 2 , Figure 3The second drive structure 23 uses a pneumatic push rod, and the third drive structure 24 uses an electric turntable. The negative pressure suction cup 22 is connected to a vacuum pump and a corresponding gas pipeline to create negative pressure inside. A vacuum solenoid valve and a pressure reducing valve are installed between the gas pipeline and the negative pressure suction cup 22. The second drive structure 23 pushes the transfer block 21 downward. The negative pressure suction cup 22 above the storage mechanism 4 picks up the top pad in the storage tank 41. Then, the second drive structure 23 resets, causing the transfer block 21 to move upward. When the conveying mechanism 1 conveys the bottle cap to the area below the tablet placement mechanism 2, the third drive structure 24 drives the transfer block 21 to rotate 180° clockwise, thus picking up the pad. The negative pressure suction cup 22 is located above the bottle cap. Then, the second drive structure 23 pushes the transfer block 21 downward to place the pad inside the bottle cap. At this time, the vacuum solenoid valve switches the negative pressure suction cup to the release mode and adjusts the positive pressure airflow during release with the pressure reducing valve so that the pad can be successfully placed inside the bottle cap. At the same time, the negative pressure suction cup 22 located above the storage mechanism 4 picks up the top pad in the storage tank 41. Then, the second drive structure 23 resets and causes the transfer block 21 to move upward. Finally, the conveying mechanism 1 conveys the bottle cap with the completed pad assembly toward the tablet pressing mechanism 3 and conveys the bottle cap to be assembled with the pad to the bottom of the tablet placement mechanism 2. Furthermore, referring to Figure 1 , Figure 2 , Figure 4 The fourth drive structure 32 adopts a pneumatic pusher. When the bottle cap with a gasket inside is conveyed by the conveying mechanism 1 and reaches the bottom of the tablet pressing mechanism 3, the fourth drive structure 32 pushes the tablet pressing block 31 to move downward. The bottom of the tablet pressing block 31 abuts against the gasket inside the bottle cap and presses the gasket into the bottle cap. Then the fourth drive structure 32 resets and pulls the tablet pressing block 31 to move upward. After the gasket is pressed into the bottle cap, the conveying mechanism 1 continues to convey the bottle cap, so that the bottle cap finally enters the discharge track 15 from the output end 12. It should be further explained that, referring to Figure 1 , Figure 2 , Figure 5The storage tank 41 has a feeding base plate 43 at its inner bottom. The bottom of the feeding base plate 43 has a fifth drive structure 44 that causes it to reciprocate vertically. The fifth drive structure 44 is an electric push rod. A first detection element 45 is located near the top of the storage tank 41. The first detection element 45 is a photoelectric sensor, which consists of two sensors: one for emitting light signals and the other for receiving light signals. The storage mechanism 4 is located at the center of the annular structure of the conveying mechanism 1. A connection is established between the storage mechanism 4 and the conveying mechanism 1. There is a clearance that allows the conveying mechanism 1 to rotate; the storage mechanism 4 preferably has two storage slots 41, one of which is located below a negative pressure suction cup 22 of the sheet placement mechanism 2. The first drive structure 42 is an electric turntable. When the pad in one of the storage slots 41 is consumed, the first drive structure 42 drives the storage mechanism 4 to rotate, so that the two storage slots 41 exchange positions, so that the other storage slot 41 containing the pad rotates to below the negative pressure suction cup 22, so that the sheet placement mechanism 2 can always pick up the pad from the storage mechanism 4 through the negative pressure suction cup 22. During the process of the feeding mechanism 2 picking up the gaskets inside the storage tank 41 and placing them inside the bottle cap, the top gasket inside the storage tank 41 is picked up by the negative pressure suction cup 22. The height of the stacked gaskets inside the storage tank 41 will gradually decrease. When the height of the stacked gaskets decreases to the point that the first detection element 45 can no longer detect the gaskets, the fifth drive structure 44 will push the feeding base plate 43 upward, so that the top gasket inside the storage tank 41 is always at the top of the storage tank 41, realizing automatic feeding of the gaskets. When the fifth drive structure 44 pushes the feeding base plate 43 upward to the limit, it means that the gaskets inside the storage tank 41 have been consumed or are about to be consumed and become an empty tank. At this time, the first drive structure 42 drives the storage mechanism 4 to rotate, so that the two storage tanks 41 exchange positions. At the same time, the fifth drive structure 44 at the bottom of the empty tank resets and pulls the feeding base plate 43 downward. The staff only needs to replenish the gaskets inside the empty tank periodically.

[0022] As one of the preferred embodiments of this utility model, refer to Figure 2 A gasket detection mechanism 5 is provided above the conveying mechanism 1. The gasket detection mechanism 5 is located between the tablet release mechanism 2 and the tablet pressing mechanism 3 along the conveying direction of the conveying mechanism 1. A second detection element 51 and an air blowing structure 52 are provided at the bottom of the gasket detection mechanism 5. The second detection element 51 faces downward toward the conveying mechanism 1. The air blowing structure 52 generates airflow from the center near the conveying mechanism 1 outward. The air blowing structure 52 adopts a common nozzle structure and is connected to a high-pressure air pump on one side through a gas pipeline. During the assembly of gaskets, it is inevitable that the negative pressure suction cup 22 may not adhere firmly, causing the gasket to fall off. This results in some bottle caps not having a gasket properly placed inside. The gasket detection mechanism 5 is mainly used to detect whether the gasket has been successfully placed inside the bottle cap. The second detection element 51 uses a color sensor. Since the gasket and the bottle cap are different colors, the second detection element 51 determines whether there is a gasket inside the bottle cap by detecting the color of the bottom inside the bottle cap. If no gasket is detected inside the bottle cap, the air blowing structure 52 blows the bottle cap away from the conveying mechanism 1. A container is set on one side of the conveying mechanism 1 opposite to the gasket detection mechanism 5 to hold the bottle caps that fall off due to the air blowing, so as to prevent the bottle caps from falling to the ground and causing a mess inside the bottle cap processing workshop.

[0023] As one of the preferred embodiments of this utility model, refer to Figure 1 , Figure 2 The tablet placement mechanism 2 has a third detection element 25 facing the conveying mechanism 1 on one side, and the tablet pressing mechanism 3 has a fourth detection element 33 facing the conveying mechanism 1 on one side. Both the third detection element 25 and the fourth detection element 33 are color sensors. The third detection element 25 is used to detect whether there is a bottle cap in the conveying groove 13 below the tablet placement mechanism 2. When the third detection element 25 cannot detect the presence of a bottle cap based on color, the tablet placement mechanism 2 will not perform the operation of placing the pad inside the bottle cap. The fourth detection element 33 is used to detect whether there is a bottle cap in the conveying groove 13 below the tablet pressing mechanism 3. When the fourth detection element 33 cannot detect the presence of a bottle cap based on color, the tablet pressing mechanism 3 will not perform the operation of pressing the pad.

[0024] In summary, this utility model discloses a device for assembling and pressing gaskets into the inside of bottle caps. The bottle caps are sequentially conveyed below the gasket placement mechanism 2 and the gasket pressing mechanism 3 by the conveying mechanism 1. When the bottle caps are conveyed to the gasket placement mechanism 2, the gasket placement mechanism 2 rotates the transfer block 21 to make the two negative pressure suction cups 22 alternately complete the operation of picking up and placing the gaskets. Then, the gaskets are pressed into the inside of the bottle caps by the gasket pressing mechanism 3. In addition, the gaskets are automatically fed into the storage tank 41 by the upward movement of the bottom feeding plate 43. The negative pressure suction cups 22 press down from above the gaskets and pick them up. The bottom of the storage tank 41 supports the gaskets to ensure that the negative pressure suction cups 22 can smoothly pick up the gaskets and place them smoothly into each bottle cap, which helps to improve the processing efficiency of bottle caps.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
