Description

Technical Field

[0001] The utility model relates to the technical field of plastic bucket processing, and more specifically, it relates to a cutting device for plastic bucket processing. Background Art

[0002] In the existing technology, there are certain limitations in the cutting efficiency of the existing cutting devices for plastic bucket processing. This may be due to the sub-optimal design of the equipment or the relatively backward technology used. For example, some cutting devices may rely on slower mechanical cutting methods rather than more efficient laser or water jet cutting technologies. In addition, the degree of automation of the equipment may not be high, resulting in a need for more manual intervention during the cutting process. This not only reduces the cutting speed but also increases the possibility of human errors.

[0003] There are also inconveniences in the installation and disassembly of the cutting blades of the existing cutting devices for plastic bucket processing. The cutting blade is a key component in the cutting device, which directly affects the cutting quality and accuracy. However, the fixing methods of the cutting blades in many traditional devices may be relatively complex, requiring tools for tightening and loosening. This not only increases the operation difficulty but also prolongs the time for replacement and maintenance. In addition, frequent disassembly and installation may cause damage or deformation of the cutting blade, further affecting the cutting effect.

[0004] There are also inconveniences in clamping one end of the plastic bucket by the existing cutting devices for plastic bucket processing. The clamping of the plastic bucket is one of the key steps to ensure the smooth progress of the cutting process. However, many devices may lack an effective clamping mechanism or the clamping method is not firm enough, resulting in displacement or inclination of the plastic bucket during the cutting process, affecting the cutting quality. In addition, an inappropriate clamping method may cause damage to the plastic bucket or produce defective products. Summary of the Utility Model

[0043] In summary, when the whole equipment is in use or operation: First, install the cutting blade 7. Insert the cutting blade 7 onto the clamping rod 8, and then sleeved the clamping sleeve 10 onto the clamping rod 8. When the top end of the clamping rod 8 touches the clamping piece 11, lift the clamping piece 11.

Through the threaded engagement between the rack 28 and the gear 27, drive the gear 27 to rotate. The gear 27 drives the screw rod 24 to rotate. Since the screw rod 24 is set as a double-headed screw rod 24, the two transmission seats 25 are respectively in threaded engagement with the opposite threads at both ends of the screw rod 24, so that the two transmission seats 25 move inward simultaneously, driving the clamping plates 26 to clamp the plastic bucket.
