[0040] As an embodiment, the threading channel assembly comprises two lateral threading grooves 250, a bottom threading groove 251, a top threading groove 252 and a threading groove driving piece 253, the two lateral threading grooves 250 are respectively installed on both sides of the gantry 10 in the first direction, the two lateral threading grooves 250 correspond to the adsorption assemblies 321 of the two sets of feeding mechanisms 30 one by one, the bottom threading groove 251 is telescopically installed at the bottom of the gantry 10, the driving end of the threading groove driving piece 253 is connected to the bottom threading groove 251, the threading groove driving piece 253 drives the bottom threading groove 251 to extend, so that the two ends of the bottom threading groove 251 are butted with the bottom ends of the two lateral threading grooves 250, and the top threading groove 252 is installed at the top of the gantry 10 and is configured to butt the top ends of the two lateral threading grooves 250 with the bundling head 22, when bundling, the two lateral threading grooves 250, the bottom threading groove 251 and the top threading groove 252 form a threading channel for the bundling belt to pass through.

[0041] It can be seen that the threading channel for the bundling belt to pass through and for the bundled material is formed through the cooperation of the two lateral threading grooves 250, the bottom threading groove 251 and the top threading groove 252.

[0042] As an implementation form, the hopper assembly 310 comprises a first hopper 3100 and a second hopper 3101, the first hopper 3100 and the second hopper 3101 are vertically arranged side by side along the second direction, the first hopper 3100 and the second hopper 3101 are both configured to store a plurality of short corners stacked up and down, the lower end of each hopper is provided with a discharge port, the discharge port of the second hopper 3101 is higher than the discharge port of the first hopper 3100, and each hopper is provided with an openable and closable replenishment channel above, the pushing assembly is arranged directly below the hopper assembly, the pushing assembly 311 comprises a pushing driving member 312 and a pushing mechanism 313, the driving end of the pushing driving member 312 is connected to the pushing mechanism 313, the pushing mechanism 313 comprises a carrying part 314 for receiving a short corner, the pushing driving member 312 drives the carrying part 314 to move back and forth along the second direction to receive the shortest corner on the bottom layer in the first hopper 3100 or the second hopper 3101, and to send the received short corner to the taking position,

[0043] When the first hopper 3100 is in the non-empty state, the pushing driving member 312 drives the carrying part 314 to move to the position directly below the discharge port of the first hopper 3100 to receive the shortest corner on the bottom layer in the first hopper 3100 each time, and to send the received short corner to the taking position,

[0044] When the first hopper 3100 is in the empty state, the pushing driving member 312 drives the carrying part 314 to move to the position directly below the discharge port of the second hopper 3101 to receive the shortest corner on the bottom layer in the second hopper 3101 each time, and to send the received short corner to the taking position.

[0045] It should be noted that the cross section of the short corner is "∟" type, the taking position is the taking position of the short corner, and the taking device automatically places the short corner at the taking position in the corresponding corner of the material after picking up the short corner.

[0046] It can be seen that by arranging the hopper assembly to comprise the double-hopper structure of the first hopper 3100 and the second hopper 3101, the storage amount of the short corners of the strapping machine is doubled, frequent shutdown for replenishment is avoided, and the strapping efficiency of the strapping machine is improved; at the same time, the pushing mechanism can automatically feed the short corners in the first hopper 3100 and the second hopper 3101 respectively, the feeding efficiency is improved, the overall structure is compact, and the occupied space is small.

[0047] As an implementation form, the pushing mechanism 313 comprises a base 3130 and a sliding piece 3131, the sliding piece 3131 is reciprocatingly installed on the base 3130 in the second direction, a fixed end of the pushing driving piece 312 is installed on the base 3130, a driving end of the pushing driving piece 312 is connected to a first end of the sliding piece 3131, the carrying part 314 is arranged at a second end of the sliding piece 3131, the second end is close to the adsorption assembly 321, the carrying part 314 has a “∟” type carrying surface 3140 for carrying the short angle, a pushing piece 3132 is installed on the sliding piece 3131 on a side away from the second end of the carrying surface 3140, a height of the pushing piece 3132 above the carrying surface 3140 is not greater than a thickness of a single short angle, so that the pushing piece 3132 only sends one short angle to the taking position at a time, the base 3130 is installed with a first limiting piece 3133 between the discharge port of the first bin 3100 and the discharge port of the second bin 3101, the first limiting piece 3133 is configured to limit the short angle in the second bin 3101 on the pushing piece 3132 when the carrying part 314 receives the short angle in the first bin 3100.

[0048] Specifically, the sliding piece 3131 is reciprocatingly installed on the base 3130 in the short angle feeding direction through a sliding pair composed of a linear guide rail and a sliding block.

[0049] It can be seen that through cooperation of the pushing driving piece 312, the sliding piece 3131 and the pushing piece 3132, the short angles in the first bin 3100 and the second bin 3101 are automatically pushed to the taking position, and the pushing piece 3132 can only push one short angle at a time, and the first limiting piece 3133 is used for limiting when the short angle in the first bin 3100 is fed, so as to avoid taking out the short angle in the second bin 3101. The pushing mechanism 313 has the advantages of simple structure, easy implementation, high feeding accuracy and stable and reliable operation.

[0050] As an implementation form, the base 3130 is further installed with a second limiting piece 3134, the first limiting piece 3133 and the second limiting piece 3134 are respectively located at two ends of the discharge port of the second bin 3101 in the short angle feeding direction, so as to limit the short angle in the second bin 3101 on the pushing piece 3132 at the two ends when the carrying part 314 receives the short angle in the first bin 3100.

[0051] It can be seen that through cooperation of the first limiting piece 3133 and the second limiting piece 3134, the short angle in the second bin 3101 on the pushing piece 3132 is limited at the two ends when the carrying part 314 receives the short angle in the first bin 3100, so as to avoid large displacement of the short angle in the second bin 3101, and cause damage to the short angle.

[0052] As an implementation form, the bottom of the second hopper 3101 is provided with a connecting piece 3135 configured to support the second hopper 3101, and the connecting piece 3135 is also configured to limit the short angle at the discharge port of the second hopper 3101, the bottom end of the connecting piece 3135 is installed on the base 3130, a plurality of adjusting grooves 3136 are arranged on the connecting piece 3135 in the short angle feeding direction and are spaced apart, the top end of the second limiting piece 3134 is clamped into a corresponding adjusting groove 3136, the first end of the sliding piece 3131 is further provided with a third limiting piece 3137 configured to limit the short angle on the bearing part 314 from the outside, and the third limiting piece 3137 is also configured to cooperate with the first limiting piece 3133 to make the bearing part 314 receive one short angle at a time, the distance between the third limiting piece 3137 and the first limiting piece 3133 is slightly greater than the length of one short angle, and only one short angle can be accommodated between the third limiting piece 3137 and the first limiting piece 3133, so that the bearing part 314 can only receive one short angle at a time for feeding, and meanwhile the third limiting piece 3137 can prevent the short angle from sliding off the bearing part 314 during the process of being sent to the taking position after being taken.

[0053] Specifically, two baffles 3138 are arranged in parallel and spaced apart between the first limiting piece 3133 and the second limiting piece 3134 on the base 3130, and the two baffles 3138, the first limiting piece 3133 and the second limiting piece 3134 form a space below the discharge port of the second hopper 3101 to accommodate the short angle.

[0054] It can be seen that the connecting piece 3135 is arranged to support the second hopper 3101, and also to limit the short angle at the discharge port of the second hopper 3101, so that the short angle in the second hopper 3101 abuts against the inner wall; by arranging a plurality of adjusting grooves 3136 on the connecting piece 3135, the installation position of the second limiting piece 3134 on the connecting piece 3135 is adjusted to realize the adjustment of the connecting piece 3135 in the short angle feeding direction, so that the connecting piece 3135 can limit the short angles of different sizes in the second hopper 3101, and the compatibility is improved.

[0055] As an implementation form, the pushing driving piece 312 adopts a pneumatic cylinder, and the base 3130 is provided with at least a first sensing assembly and a second sensing assembly, the first sensing assembly is configured to control the pushing driving piece 312 to move the bearing part 314 below the first hopper 3100 to receive the short angle in the first hopper 3100 and send the received short angle to the taking position, and the second sensing assembly is configured to control the pushing driving piece 312 to move the bearing part 314 below the second hopper 3101 to receive the short angle in the second hopper 3101 and send the received short angle to the taking position.

[0056] Specifically, the first sensing assembly and the second sensing assembly are arranged at intervals along the short guard angle feeding direction, and the first sensing assembly and the second sensing assembly each include a sensing component and a solenoid valve, and the stroke of the pushing driving member 312 is controlled through cooperation of the sensing component and the solenoid valve.

[0057] The specific working principle of the feeding mechanism 30 proposed in the embodiment is as follows:

[0058] When the first bin 3100 is in a non-empty state (i.e., there are short guard angles in the first bin 3100), the pushing mechanism 313 feeds the short guard angles in the first bin 3100, the first sensing assembly controls the pushing driving member 312 to move the bearing part 314 to be directly below the discharge port of the first bin 3100, at this time, the bottom layer of short guard angles in the first bin 3100 falls to the bearing surface 3140 by gravity, and the bottom layer of short guard angles in the second bin 3101 falls to the pushing member 3132 by gravity, the pushing driving member 312 drives the sliding member 3131 to move to move the short guard angles on the bearing surface 3140 to the taking position, and the process is repeated until the first bin 3100 is in an empty state (i.e., there are no short guard angles in the first bin 3100), and it should be noted that in the process of moving the short guard angles on the bearing surface 3140 to the taking position, the first limiting member 3133 limits the movement of the bottom layer of short guard angles in the second bin 3101 following the sliding member 3131.

[0059] When the first bin 3100 is in an empty state, the pushing mechanism 313 switches to feed the short guard angles in the second bin 3101, the second sensing assembly controls the pushing driving member 312 to move the bearing part 314 to be directly below the discharge port of the second bin 3101, the bottom layer of short guard angles in the second bin 3101 falls to the bearing surface 3140 by gravity, and the pushing driving member 312 drives the sliding member 3131 to move to move the short guard angles on the bearing surface 3140 to the taking position, and the process is repeated until the second bin 3101 is in an empty state.

[0060] The first bin 3100 and the second bin 3101 are manually replenished, and after replenishment, the feeding mechanism 30 is repeatedly fed.

[0061] As an implementation, the first hopper 3100 is provided with a replenishment channel on the side close to the second hopper 3101 in the second direction, the first side of the second hopper 3101 in the first direction is hinged to one side of the replenishment channel of the first hopper 3100, the second side of the second hopper 3101 in the first direction is detachably arranged on the other side of the replenishment channel of the first hopper 3100 through the first locking assembly 33, when the first locking assembly 33 is unlocked, the first side of the second hopper 3101 rotates around the first hopper 3100 to open the replenishment channel of the first hopper 3100 for replenishment of the first hopper 3100; when the first locking assembly 33 is locked, the second hopper 3101 closes the replenishment channel of the first hopper 3100 on the side close to the first hopper 3100 in the second direction, and the closing piece 34 is detachably arranged on the replenishment channel of the second hopper 3101.

[0062] It should be noted that, due to installation requirements, the side of the first hopper 3100 close to the operator in the first direction is used as a mounting surface, and the other side of the first hopper 3100 close to the material in the first direction, so neither side of the first hopper 3100 in the first direction is suitable as a replenishment port. The side of the first hopper 3100 away from the second hopper 3101 in the second direction is arranged close to the lifting piece 23 and used as a mounting surface, so the side of the first hopper 3100 close to the second hopper 3101 in the second direction is used as a replenishment port.

[0063] Specifically, one side of the closing piece 34 is hinged to one side of the replenishment channel of the second hopper 3101 through a hinge, and the other side of the closing piece 34 is detachably arranged on the other side of the replenishment channel of the second hopper 3101 through the second locking assembly 35, when the second locking assembly 35 is unlocked, the one side of the closing piece 34 rotates around the second hopper 3101 to open the replenishment channel of the second hopper 3101 for replenishment of the second hopper 3101, and when the second locking assembly 35 is locked, the closing piece 34 closes the replenishment channel of the second hopper 3101.

[0064] It can be seen that, by arranging the first hopper 3100 and the second hopper 3101, the amount of corner protector stored in the strapping machine is doubled, frequent downtime for replenishment is avoided, and the strapping efficiency of the strapping machine is improved, and by hinging the first hopper 3100 and the second hopper 3101, the first hopper 3100 is provided with a replenishment channel on the side close to the second hopper 3101 in the second direction, and the second hopper 3101 closes the replenishment channel of the first hopper 3100 on the side close to the first hopper 3100 in the second direction. Not only can the installation requirements of the hopper assembly be met, but also the structure is simple, the design is ingenious, replenishment is convenient, and costs are saved.

[0065] The specific working principle of the above-mentioned short corner protector automatic feeding and strapping integrated machine is as follows:

[0066] The conveying line automatically conveys the material to the bundling position,

[0067] The lifting driving assembly 24 drives the lifting piece 23 to descend to a preset height, so that the two sets of feeding mechanisms 30 descend to a suitable height,

[0068] The feeding assembly 31 of the two sets of feeding mechanisms 30 works, and automatically feeds the two short corner guards to the material taking position respectively,

[0069] The feeding assembly 32 works, picks up the short corner guard at the material taking position, rotates 45° to turn the short corner guard to a horizontal state, and then moves the picked short corner guard to the edge corner of the material to release, so that the short corner guard is automatically placed on the corresponding edge corner of the material,

[0070] The bundling mechanism 20 works to vertically bundle the material at the position where the short corner guard is arranged on the material.

[0071] The above examples only illustrate the basic principles and characteristics of the present application, and the present application is not limited by the above examples. Various changes and modifications can be made without departing from the spirit and scope of the present application, and these changes and modifications all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
