[0002] A baler, also known as a strapping machine, a banding machine or a strapping machine, uses strapping tape to strap products or packages, then tightens them and combines the two ends by hot-melt bonding with a heating head. The function of a baler is to reinforce the packaged items so that the items will not scatter during transportation and storage due to loose strapping.

When the tightening motor 1 is reversed, it drives the fan-shaped tooth cam 4 to weld and pack the items. The service life is longer and the maintenance is more convenient, which brings better usage prospects.

[0019] like Figures 1 to 3As shown, the outer side surface of the planetary gear seat 7 is rotatably connected to the sector-shaped tooth cam 4, the sector-shaped tooth cam 4 is meshed with the planetary gear seat 7, the outer side surface of the main body seat 16 is fixedly connected to the tightening tooth plate seat 10, the outer side surface of the main body seat 16 is fixedly connected to the small motor 15, the outer side surface of the small motor 15 is fixedly connected to the bracket 13, the outer side surface of the main body seat 16 is fixedly connected to the turbine case cover 14, the upper surface of the main body seat 16 is fixedly connected to the handle 6, the sector-shaped tooth cam 4 is used to generate heat and perform welding, the spring seat 5 is used to adjust the pressure on the spring to realize the replacement of the melt-cut PP belt and the PET belt, and the small motor 15 is used to imitate a human hand and give a welding command to the welding button by a pressure.

[0020] like Figure 3 and Figure 4 As shown, a transmission tooth 18 runs through the center of the turbine 11, and the outer wall of the transmission tooth 18 is meshed with the planetary gear set 17. There are three sets of planetary gear sets 17, and the transmission tooth 18 is located at the connection seam of the three sets of planetary gear sets 17. The outer wall of the planetary gear set 17 is meshed with a gear ring 22, and the outer side surface of the gear ring 22 is fixedly connected to the second rotating sleeve 21. The interior of the second rotating sleeve 21 is fixedly connected to a transmission wheel 19, and the outer wall of the transmission wheel 19 is sleeved with a first rotating sleeve 20.

[0021] like Figures 1 to 3As shown, the tightening motor 1 is a brushless motor, and the tightening motor 1 can realize forward and reverse rotation through control. The fan-shaped tooth cam 4 is used to generate heat for welding. The outer side of the handle 6 is fixedly connected with a rubber block, and the rubber block is used for anti-skid.

This advantage is a huge support for the stability of model operation. Usually, the service life is in the order of tens of thousands of hours, but due to different bearings, the service life of brushless motors is also very different. Brushless motors are usually digital frequency conversion control with strong controllability.
