Description

Technical Field

[0001] This utility model relates to the field of plastic bag manufacturing, specifically to a linked high-speed bag making machine. Background Technology

[0002] In daily production, film bags (plastic bags) are commonly used to carry items, and their usage in daily life is enormous. The production of film bags usually requires the use of high-speed bag making machines.

[0003] The fully automatic bag making machine uses a servo motor to drive the feeding and control the bag length, and a frequency converter motor to drive the heating and cutting blade to cut the bag up and down. A silicone rubber roller is installed under the heat-sealing and cutting blade. The heat-sealing and cutting blade heat-seals and cuts the fed film roll material to form the bag. Due to the action of the heat-cutting blade, the support roller (rubber roller) is often damaged. At the same time, it is easy to cause heat radiation damage to the feeding device behind the cut plastic film, which affects the product quality and the life of the equipment.

[0004] Typically, the cooling blade, hot shearing device, and bag pressing device in a high-speed bag making machine require different motors to drive different drive shafts so that the three parts can operate independently. This requires the use of multiple servo motors, which increases the overall cost of the machine and also makes the equipment larger due to the installation of too many devices.

[0005] Therefore, there is a need for a high-speed bag-making machine that can reduce the number of drive motors, adopt a linkage mechanism, and simultaneously control the movement of three mechanisms to simplify the equipment. Utility Model Content

[0006] This utility model provides a linkage-type high-speed bag making machine. A drive motor A is connected to the main shaft, and eccentric wheels A, B, and C are set on the main shaft to control the operation of the cooling knife, shearing device, and bag pressing device. This effectively reduces the use of drive motors in the high-speed bag making machine, making the overall equipment more streamlined and reducing the cost and maintenance costs.

[0007] This utility model is achieved through the following technical solution:

The inner ring of the eccentric wheel B is fixedly connected to the main shaft, and the outer ring is connected to the linkage mechanism B through a connecting rod C, thereby driving the drive rods B to move up and down.

[0012] Furthermore, the linkage mechanism B includes a connecting rod A and a connecting rod B. The lower end of the driving rod B is hinged and fixed to one end of the connecting rod A, the other end of the connecting rod A is hinged and fixed to one end of the connecting rod B, the other end of the connecting rod B is fixedly connected to the driving shaft B, and the connecting rod C is fixedly hinged and fixed to the connecting rod B.

The other end of the connecting rod E is fixedly connected to the outer ring of the eccentric wheel C, and the main shaft is fixedly connected to the inner ring of the eccentric wheel C.

[0015] Furthermore, the cooling blade is provided with water holes arranged in the extension direction, and the water holes are connected to circulating water.

[0016] The beneficial effects of this utility model are as follows:

[0017] This patent uses a single drive motor A to control the operation of the cooling knife, shearing device, and bag pressing device by setting eccentric wheels A, B, and C on the same main shaft. This effectively reduces the number of drive motors used in the high-speed bag making machine, making the overall equipment more streamlined and reducing manufacturing and maintenance costs.
