The bracket assembly 20 is arranged on the body 10 and has a closing position 21; the protection assembly 30 is arranged at the closing position 21 and can be pivoted between a non-use state and a use state. When the protection assembly 30 is in the non-use state, the closing position 21 is blocked by the protection assembly 30; when the protection assembly 30 is in the use state, the protection assembly 30 is misaligned with the closing position 21.

[0040] Among them, the non-use state indicates a state in which the bag opening is not extended into the tie-opening position 21, and the use state indicates a state in which the bag opening is extended into the tie-opening position 21. In the non-use state, the protective component 30 can keep covering the tie-opening position 21, and in the use state, the bag opening is extended into the tie-opening position 21 and can push the protective component 30 and the tie-opening position 21 to be displaced from each other, thereby opening the tie-opening position 21, so that the bag opening can complete the automatic tying operation at the tie-opening position 21.

[0041] The safety protection tying machine provided by the utility model can protect the tying position 21 through the protection component 30, so that when the protection component 30 is not in use, the tying position 21 can be blocked by the protection component 30, thereby avoiding fingers and other objects from being inserted into the tying position 21 to cause misoperation, thereby improving overall safety.

[0042] Reference Figure 2 and Figure 3 As shown, the bracket assembly 20 includes: a sliding frame 22 and a forming mold 23. The sliding frame 22 is fixed on the body 10; the forming mold 23 is arranged at one end of the sliding frame 22, and is used to abut against the row of nails when tying to force the row of nails to form.

[0043] In this embodiment, when the row of nails is pushed to the position of the forming mold 23, the forming mold 23 can interact with the row of nails, thereby forcing the row of nails to be extruded and formed, thereby tightening the bag opening; optionally, the sliding frame 22 is an integrated structure, and the sliding frame 22 can be integrally formed by stamping, so that during the production process, its processing steps can be reduced, and the assembly of the safety protection tying machine can be simpler and more convenient.

[0044] Furthermore, a punching knife is provided on the sliding frame 22 , and the punching knife is slidably connected to the sliding frame 22 , and is used to push the row of nails to the tying position 21 , so that the row of nails abuts against the forming mold 23 for forming.

[0045] Among them, the punching knife can be driven by a motor and a connecting rod to move on the sliding frame 22, and the motor can be controlled by the main control module to start working. When the motor drives the punching knife to move toward the tying position 21, the row of nails can be pushed to the tying position 21 by the punching knife and abut against the forming mold 23 for forming, so that the bag opening at the tying position 21 can be fastened and fixed by the formed row of nails to complete the tying operation, and the operation is simple and convenient; it can be understood that the operation of the punching knife to push the row of nails to tie the bag can adopt the existing method, which will not be elaborated here.

[0046] Reference Figure 3 and Figure 4 As shown, the molding mold 23 includes: a bottom shell 231 and a protective cover 232, the bottom shell 231 is fixed to the sliding frame 22; the protective cover 232 and the bottom shell 231 are pivotally connected to each other, and are used to open or close the bottom shell 231; further, a trigger member 234 is provided in the bottom shell 231, and a magnetic member 233 corresponding to the trigger member 234 is provided on the protective cover 232. When the protective cover 232 and the bottom shell 231 are fixed to each other, the magnetic member 233 contacts the trigger member 234; when the protective cover 232 and the bottom shell 231 are away from each other, the magnetic member 233 is disconnected from the trigger member 234.

[0047] In this embodiment, the trigger member 234 can be a Hall sensor. When a condition such as a staple jam occurs at the tying position 21 and maintenance is required, the protective cover 232 can be pivoted open so that the magnetic member 233 and the trigger member 234 are separated from each other, and the trigger member 234 can transmit a signal to the main control module to cut off the control signal of the tying operation. At this time, even if the start switch is accidentally touched, the tying operation will not be triggered, thereby ensuring safety during the maintenance process; after the maintenance is completed, the protective cover 232 can be pivoted to close, so that the magnetic member 233 and the trigger member 234 are in contact with each other, so that the trigger member 234 can transmit a signal to the main control module again, so that the main control module can restore the tying function.

[0048] Specifically, the bottom shell 231 and the protective cover 232 are both provided with a groove 2321, and the groove 2321 constitutes the tying position 21. When the protective component 30 is not in use, the protective component 30 is located in the groove 2321, and when the protective component 30 is in use, the protective component 30 is misaligned with the groove 2321. The size of the groove 2321 can be set to be smaller than the size of a finger, so that the groove 2321 can prevent a finger from being inserted into the groove 2321 during use while facilitating the entry and exit of the bag, thereby avoiding the risk of pinching the finger and providing higher safety.

[0049] Specifically, a mounting member 235 is provided between the bottom shell 231 and the protective cover 232, the bottom shell 231 and the protective cover 232 are pivotally connected through the mounting member 235, and the protective assembly 30 is provided on the mounting member 235. The mounting member 235 and the bottom shell 231 can be fixed by screws or the like, so that the mounting member 235 has better consistency between the bottom shell 231 and the protective member.

[0050] Furthermore, the protective component 30 includes: an elastic member 31 and a shielding member 32 , wherein the elastic member 31 is fixed on the mounting member 235 , and one end thereof elastically abuts against the mounting member 235 ; the shielding member 32 is attached to the mounting member 235 , and elastically abuts against the other end of the elastic member 31 .

[0051] In this embodiment, the shielding member 32 can be pivotally connected to the mounting member 235. When the shielding member 32 and the mounting member 235 are pivotally connected, the elastic member 31 can be a torsion spring, and the two ends are respectively against between the mounting member 235 and the shielding member 32, so that the elastic member 31 can elastically push the shielding member 32 to remain at the tying position 21 for shielding, so that when it is not in use, it can prevent fingers from being inserted into the tying position 21 from above the shielding member 32, avoid accidental triggering of the tying operation, and have higher safety; when the tying operation is performed, the bag opening can be entered from the direction in which the shielding member 32 moves The tying position 21 allows the bag to first push the shielding member 32 to be displaced from the tying position 21, and then contact the start switch and control to complete the tying operation. After the bag is tied and taken out, the shielding member 32 can be restored to the position to shield the tying position 21 under the action of the elastic member 31, thereby making the tying position 21 safer and effectively avoiding misoperation; optionally, the shielding member 32 can also form a sliding connection with the mounting member 235, and the elastic member 31 can adopt a compression spring so that it can be pushed by the elastic member 31 to keep the tying position 21 blocked.

[0052] Optionally, a buckle portion is provided on the bottom shell 231, and the buckle portion is located on the side of the bottom shell 231, and is used to lock the protective cover 232 with the bottom shell 231.
