Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, specifically to a turntable structure suitable for a strip bag turning and bag-repairing machine. Background Technology

[0002] During the turning process of strip packages in multi-row packaging machines, the centrifugal force generated by the high-speed rotation of the turntable can easily cause the strip packages to be thrown off the turntable. Solutions to this problem already exist on the market, such as patent CN222555891U, which adds a package-blocking mechanism to the turntable's receiving trough.

[0003] However, the bag-holding mechanism used in this patent has obvious shortcomings: the structural design is too complex, using a combination of a flipping torsion spring mechanism and a cylinder; when the turntable is in position, the cylinder pushes the spring mechanism, generating a large impact noise; the torsion spring has insufficient durability and is prone to falling off during use; the maintenance and repair process is cumbersome, increasing equipment maintenance costs and downtime.

[0004] These defects not only affect the operational stability of the equipment, but also reduce production efficiency and product quality, necessitating an improvement solution with a simpler structure and more stable and reliable operation.

[0005] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0006] The purpose of this invention is to provide a turntable structure suitable for a strip bag turning and bagging machine, so as to overcome the above-mentioned shortcomings and deficiencies of the prior art.

The center of the feeding turntable body is connected to the transmission mechanism. The feeding turntable body is provided with a receiving groove, and a bag-blocking mechanism is provided below the receiving groove. The transmission mechanism is connected to the bag-blocking mechanism. The feeding station is located at the twelve o'clock position of the feeding turntable body, and the discharging station is located at the three o'clock position of the feeding turntable body.

[0008] The baffle mechanism includes a cylinder fixing plate, a cylinder, a spring, and a baffle. The cylinder fixing plate is connected to the lower part of the receiving groove, the cylinder fixing plate is connected to the cylinder, the piston rod of the cylinder is provided with a spring, the piston rod of the cylinder is connected to the baffle, and the baffle is connected to the receiving groove.

[0009] Furthermore, the transmission mechanism includes: a turntable fixing seat, a reducer, a servo motor, a slip ring fixing seat, and a pneumatic slip ring. One end of the turntable fixing seat is connected to the bottom end of the feeding turntable body, the other end of the turntable fixing seat is connected to one end of the reducer, the other end of the reducer is connected to the servo motor, the pneumatic slip ring is connected to the top end of the feeding turntable body through the slip ring fixing seat, the pneumatic slip ring is connected to a cylinder, and the pneumatic slip ring has a four-channel structure.

[0010] The beneficial effects of this utility model are:

[0019] The present invention will be further described below with reference to specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0020] Example 1

[0021] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 This is a schematic diagram of the bag-blocking mechanism. Figure 3 This is a diagram showing the usage state of this utility model.

[0022] like Figure 1-3As shown, a turntable structure suitable for a strip bag turning and bagging machine includes: a feeding turntable body 100, a receiving groove 200, a bag-blocking mechanism 300, a transmission mechanism 400, a feeding station 500, and a discharging station 600. The center of the feeding turntable body 100 is connected to the transmission mechanism 400. The feeding turntable body 100 is provided with a receiving groove 200, and a bag-blocking mechanism 300 is provided below the receiving groove 200. The transmission mechanism 400 is connected to the bag-blocking mechanism 300. The feeding station 500 is located at the twelve o'clock position of the feeding turntable body 100, and the discharging station 600 is located at the three o'clock position of the feeding turntable body 100.

[0023] The baffle mechanism 300 includes: a cylinder fixing plate 310, a cylinder 320, a spring 330, and a baffle 340. The cylinder fixing plate 310 is connected to the lower part of the receiving groove 200, the cylinder fixing plate 310 is connected to the cylinder 320, the piston rod of the cylinder 320 is provided with the spring 330, the piston rod of the cylinder 320 is connected to the baffle 340, and the baffle 340 is connected to the receiving groove 200.

[0024] The transmission mechanism 400 includes: a turntable fixing seat 410, a reducer 420, a servo motor 430, a slip ring fixing seat 440, and a pneumatic slip ring 450. One end of the turntable fixing seat 410 is connected to the bottom end of the feeding turntable body 100, and the other end of the turntable fixing seat 410 is connected to one end of the reducer 420. The other end of the reducer 420 is connected to the servo motor 430. The pneumatic slip ring 450 is connected to the top end of the feeding turntable body 100 through the slip ring fixing seat 440. The pneumatic slip ring 450 is connected to the cylinder 320 and has a four-channel structure.

[0025] like Figure 3 As shown, the operating principle of the turntable structure of the bag turning and bagging machine is as follows: After the bag is fed into the turntable by the conveyor, the feeding turntable body 100 rotates counterclockwise during use through the transmission mechanism 400. When the bag enters the turntable through the feeding station 500 at the 12 o'clock position, the turntable starts to rotate counterclockwise, and after reaching the discharging station 600 at the 3 o'clock position, it moves to the next station.

[0026] The innovation of this utility model lies in the improvement of the baffle mechanism 300. Addressing the problems of existing baffle mechanisms, we have developed a new baffle mechanism solution that is simple in structure and reliable in operation. This design employs a pneumatic control system to cleverly achieve precise lifting and lowering control of the baffle. Its working principle is as follows: The mechanism uses a single-acting cylinder as the core driving element, achieving precise control of the baffle through the following method: The baffle 340 is connected to the receiving groove 200, which has a slit structure. The size of the baffle 340 is smaller than this slit, allowing the baffle 340 to move up and down within this slit during use. Lowering action: When air enters the cylinder 320, the air pressure pushes the piston rod to contract, causing the baffle 340 to descend smoothly into position. Raising action: When the air source is disconnected, the rebound force of the spring 330 on the piston rod automatically pushes the piston rod to extend, causing the baffle 340 to quickly rise back to its original position. Compared to traditional technologies, this design simplifies the structural design: a single-acting cylinder replaces the complex flipping torsion spring mechanism, significantly reducing structural complexity; it innovates the air source transmission: the cylinder's power source adopts a four-channel pneumatic slip ring design, effectively solving the problem of air pipe entanglement caused by the continuous unidirectional rotation of the turntable; it ensures smooth and reliable operation: the cylinder and spring work together, resulting in smooth operation and effectively reducing impact noise; and it is easy to maintain: standardized components make it easy to disassemble and assemble, significantly reducing maintenance difficulty and time costs.

[0027] In summary, this utility model not only solves the problem of the strips being thrown out, but also overcomes the various defects of traditional strip-blocking mechanisms, improving the overall performance and reliability of the equipment.

[0028] Compared with traditional technology, this utility model optimizes and improves the baffle mechanism, simplifies the structure, and avoids the problems of increased cost and reduced lifespan caused by complex structure; the improved baffle mechanism is raised and lowered by a cylinder, which avoids the air pipe from getting tangled due to the turntable rotating in the same direction.

[0029] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
