Description

Technical Field

[0001] The utility model relates to the technical field of bag making equipment, in particular to a wing-type bottom closing system. Background Art

[0002] Currently, most bag making machine bottom systems on the market are chain-type bottom closing systems;

[0003] The chain-type bottom-closing system has some disadvantages, such as:

[0004] 1. The chain is not stable when closing the bottom. Sometimes the chain is stretched and the chain moves out of position, which may cause the bottom to fail to close or damage other parts of the machine.

[0005] 2. The chain bottom requires a large installation space and has great limitations. For example, this design can be used to close small bags, but it cannot be used if you change to larger bags.

[0006] 3. Installation and debugging are troublesome. During installation, the two sides of the chain need to be parallel, and the chain links need to be aligned. If they are not aligned, they will hit other parts of the machine. During debugging, the position of the closing rod needs to be adjusted according to the number of chain links.

[0007] 4. It is highly dangerous because it is chain-driven and runs at high speed. If the chain is not installed properly or is not aligned, it is easy to go off track and cause parts to fall off and injure people.

[0008] 5. Since it uses chain drive, it requires frequent maintenance and lubrication, which is time-consuming.

[0009] Therefore, improvements must be made to address the above-mentioned defects. Utility Model Content

[0032] The technical solution is driven by a servo motor 10, and rotates closely against the large drum wheel 1 of the bag making machine; therefore, as long as it is synchronized with the large drum wheel 1 of the bag making machine, the function of stably closing the bottom of the paper bag can be achieved; there is only one servo motor 10 and a transmission shaft 16 to drive the closing wing, which occupies a small space and is easy to install; there are no limitations, and the bottom of the bag can be stably closed regardless of the size of the bag; because the servo motor 10 is driven through the synchronous belt 11, there is no need for debugging, counting chain links and replacing the chain, and it can be used as long as the servo motor 10 is synchronized; there is no risk of flying parts and damaging the machine; because it is a synchronous belt drive, there is no need for frequent maintenance, and it can be used stably as long as the gears are lubricated regularly, and it will not throw lubricating oil like a chain or need to be cleaned frequently, saving time.

[0033] In this technical solution:

[0034] The bag bottom pressing wheel 3 is used to flatten the bottom of the bag with the bottom opened by the bag making machine. The large drum wheel 1 of the bag making machine is the core component of the bag making machine, and the edge clamp and the center clamp are integrated, and the first clamp and the second clamp are integrated. It is a prior art and will not be described in detail here. The inserting knife mechanism 9 is used to insert the bag with the bottom opened by the bag making machine into the clamp of the large drum wheel 1 of the bag making machine. The wing-type closing system 6 is used to re-close the bottom of the bag with the bottom opened by the bag making machine to complete the production of paper bags. The servo motor 10 is used as the power source of the wing-type closing system 6. The synchronous belt 11 is used to transmit the power of the servo motor 10 to the synchronous pulley 13. The synchronous pulley 13 is driven by the servo motor 10 through the driving wheel and the synchronous belt 11 to achieve rotational motion. The first bevel gear 14 and the third bevel gear 15, the second bevel gear and the fourth bevel gear, two sets of corresponding bevel gears cooperate to change the direction of rotation, so that the first closing wing 19 and the second closing wing 20 perform rotational motion, and realize the function of closing the bottom of the paper bag. The transmission shaft 16 is driven by the servo motor 10 through the driving wheel, the synchronous belt 11 and the synchronous pulley 13 to rotate and connect the bevel gears corresponding to the first closing wing 19 and the second closing wing 20. The first closing wing 19 and the second closing wing 20 rotate to achieve the function of closing the bottom of the paper bag. The transmission pressure wheel 22 is used to transmit the paper bag closed by the first closing wing 19 and the second closing wing 20 to the next mechanism, and at the same time, it will press the bottom of the paper bag closed by the first closing wing 19 and the second closing wing 20. The pressure wheel 7 is used to press the paper bag to prevent the first closing wing 19 and the second closing wing 20 from deviating or running away when the paper bag is rotated. The air blowing pipe 8 is used to blow the bag bottom inserted by the inserting knife mechanism 9 away from the large drum wheel 1 of the bag making machine, preparing for the wing-type closing system 6 to close the bag bottom. The transmission guard strip 25 is used to escort the paper bag to the next mechanism.

[0035] Working principle of the whole machine:

[0036] The bottom of the bag is flattened by the bottom pressing wheel 3 on the big drum 1 of the bag making machine, and then when it reaches the inserting knife mechanism 9, the inserting knife inserts the bottom part of the bag into the first and second clamps of the big drum 1 of the bag making machine, and the clamps clamp the bag. At the same time, the big drum 1 of the bag making machine rotates, and when it rotates to a certain angle, the air blowing pipe 8 will blow the upper half of the bottom of the paper bag away from the big drum 1 of the bag making machine, so that the bottom part of the bag is not close to the big drum 1 of the bag making machine. At the same time, the pressing wheel 7 will press the paper of the paper bag, and then the first closing wing 19 and the second closing wing 20 will rotate under the drive of the servo motor 10 of the wing-type closing system 6 to close the bottom of the paper bag.

[0037] The servo motor 10 on the wing-type closing system 6 rotates the transmission shaft 16 through the driving wheel, the synchronous belt 11 and the synchronous pulley 13. There are two sets of bevel gears on the transmission shaft 16, and the two sets of bevel gears and the corresponding closing wings are installed symmetrically. Therefore, when the servo motor 10 drives the transmission shaft 16 to rotate, the two sets of bevel gears will change the rotation direction under the drive of the transmission shaft 16, so that the first closing wing 19 and the second closing wing 20 rotate against the large drum wheel 1 of the bag making machine, and realize the function of closing the bottom of the paper bag.

[0038] For example, in some embodiments, the bag making machine drum wheel 1 is provided with side panels 2 at both ends. The side panels 2 are used for installing and connecting the bag making machine drum wheel 1 and other components. The bearing 24 is provided on the side panel 2 on the right side.

[0039] For example, in some embodiments, a conveying guard strip 25 that matches the conveying pressure wheel 22 is provided on one side of the conveying pressure wheel 22. In this way, the paper bag can be smoothly conveyed to the next mechanism.

[0040] For example, in some embodiments, the transmission pressure wheel 22 is connected to the two side plates 2 via a transmission pressure wheel shaft 23 .

[0041] For example, in some embodiments, there are multiple pressing wheels 7 , and a pressing wheel connecting plate 26 is provided on the pressing wheel 7 . The pressing wheel connecting plate 26 is connected to the two side plates 2 via a pressing wheel connecting shaft 27 .

[0042] For example, in some embodiments, a plurality of blowing holes 28 are provided below the blowing pipe 8. The blowing pipe 8 is connected to an external air source.

[0043] For example, in some embodiments, a first protective cover is provided on the outer side of the first bevel gear 14, the third bevel gear 15 and the first closing shaft 18, and a second protective cover 17 is provided on the outer side of the second bevel gear, the fourth bevel gear and the second closing shaft 21. The first bevel gear 14, the second bevel gear 15, the third bevel gear and the fourth bevel gear are wrapped by the first protective cover and the second protective cover 17, so that the first bevel gear 14, the second bevel gear 15, the third bevel gear and the fourth bevel gear will not be thrown out of lubricating oil or need to be cleaned frequently like a chain drive, and the first bevel gear 14, the second bevel gear 15, the third bevel gear and the fourth bevel gear will be protected.

[0044] For example, in some embodiments, a third protective cover 12 is disposed outside the driving wheel. The third protective cover 12 protects the driving wheel.

[0045] For example, in some embodiments, the knife inserting mechanism 9 is connected to the two side plates 2, the bag bottom pressing wheel 3 is provided with a bag bottom pressing wheel connecting plate 4, and the bag bottom pressing wheel connecting plate 4 is connected to the two side plates 2 through the bag bottom pressing wheel shaft 5.

[0046] For example, in some embodiments, the transmission shaft 16 is connected to the two side plates.

[0047] To sum up, the utility model is driven by a servo motor and rotates closely against the large drum wheel of the bag making machine; therefore, as long as it is synchronized with the large drum wheel of the bag making machine, the function of stably closing the bottom of the paper bag can be achieved; there is only one servo motor and a transmission shaft to drive the closing wing, which occupies a small space and is easy to install; there are no limitations, and the bottom of the bag can be stably closed regardless of the size of the bag; because the servo motor is driven through a synchronous belt, there is no need for debugging, counting chain links and replacing the chain, and it can be used as long as the servo motor is synchronized; there is no risk of flying parts and damaging the machine; because it is driven by a synchronous belt, there is no need for frequent maintenance, and it can be used stably as long as the gears are lubricated regularly, and it will not throw lubricating oil like a chain or need to be cleaned frequently, thus saving time.
