Background

The steel band bundling machine is a machine device for bundling objects by using steel bands, the width of the steel bands for bundling is usually 13-19 mm, and wide bundling steel bands with the width of 40-50mm can be adopted according to different bundled goods, the bundled objects can be various steel coils, such as hot-rolled steel coils, cold-rolled steel coils, galvanized steel coils and the like, various steel tubes, such as seamless steel tubes and galvanized steel tubes, and various bars, such as screw steel and round steel.

The bundling machine locks the steel belt through the lock catch after the steel belt is fastened in the bundling process, so that bundling is completed. As shown in fig. 12, the bundling latches are generally classified into a closed latch having a closed chamber and an open latch having an open type. Closed-type shackle operations are complex and are commonly used in manual balers, which typically employ an open-type shackle. Compared with an open lock, the opening height H of the closed lock is smaller than the opening height H of the open lock, so that the steel belt is harder to pass through the closed lock, the bundling operation is more complex, and automation is difficult to realize.

Further, referring to fig. 13A, for the closed lock catch, an operator can pass the steel belt 11 through the closed cavity of the lock catch 11 from one end and pass out from the other end in the bundling process, after bundling the goods 15, the operator again passes into the lock catch 14, the tail end of the steel belt is manually folded back in the opposite direction after passing out to form the bending part 111, then the steel belt 11 is tightened, the bending part 111 is extruded between the goods 15 and the lock catch 14, and the steel belt 11 is not pulled out from the lock catch in the tightening process of the steel belt due to the bending part 111, so that the bending part 111 can enable the steel belt 11 to bear larger tension in the tightening process, thereby bundling the goods more tightly.

For the open type lock, as shown in fig. 13B, the lock covers the steel belt, and after the steel belt is tightened, the open type lock is snapped by the snap-in mechanism, so that the binding is completed. The open type fastener is free from bending portions, and the tension applied to the steel strip 112 is relatively small, which results in a relatively low binding force with respect to the closed type fastener, and on the other hand, the lower layer of the steel strip 112 is easily removed from the fastener after the completion of binding due to the absence of folding portions.

Referring to fig. 1, 2 and 3, the steel belt guiding device 1, the steel belt compacting device 2, the steel belt tensioning device 3 and the fixing base 4 are fixedly arranged from top to bottom. The compaction cylinder 22 on the steel belt compaction device 2 is fixedly connected through the supporting plate 34 on the steel belt tensioning device 3.

As shown in fig. 3, the steel belt guide 1 is provided with steel belt guide holes, the steel belt guide holes 33 of the steel belt pressing device 2, and the steel belt guide rods 31 of the steel belt tensioning device 3, which are communicated with each other, and pass through the steel belt 11, as shown by a broken line in fig. 3.

As shown in fig. 3 and 4, when the steel belt 11 is fed from the belt storage 13, the steel belt 11 enters the steel belt guide hole by guiding the guide wedge 12 on the steel belt guiding device 1, and the steel belt enters the steel belt guide hole 23 of the steel belt compacting device 2 due to the continuous feeding of the steel belt, and then the steel belt is prevented from being fed difficultly under the steel belt guide hole 23 due to the chamfering effect on the steel belt guide block 211, namely, the steel belt guide continues to enter the steel belt guide rod 31 of the steel belt tensioning device 3, and enters the fixed base 4 as the steel belt continues to enter the fixed base 4 until the lower end face of the fixed base 4 is reached.

When the steel belt is required to be tensioned, the pressing block 26 of the steel belt pressing device 2 is pressed to the cushion block 27, the steel belt positioned in the steel belt pressing shell 25 is tightly fixed, and then the tensioning cylinder in the tensioning cylinder placing shell 33 is started, so that the piston rod of the tensioning cylinder stretches, the upper end part of the steel belt tensioning device 3, the steel belt pressing device 2 and the steel belt guiding device 1 move upwards, the steel belt is tensioned, and the tensioning of the steel belt is realized.

The working principle of the steel belt compacting device 2 is as follows: when the steel strip needs to be compressed, the compressing cylinder 22 is started to enable the piston rod of the compressing cylinder 22 to move upwards, and as the compressing cylinder 22 is hinged with the connecting rod 24 through the hinge shaft and the hinge shaft sliding groove is formed in the connecting rod 24, when the compressing cylinder 22 moves upwards, the hinge shaft moves in the hinge shaft sliding groove and moves upwards with the left end part of the connecting rod 24, namely, the connecting rod 24 rotates around the shaft rod, at the moment, the right end part of the connecting rod 24 moves downwards in an arc shape, and as the straight line is shortest between the two points, when the pressing block 26 at the right end of the connecting rod 24 is at the level of the connecting rod 24, the distance between the pressing block 26 and the cushion block 27 is shortest, namely, the pressing block 26 presses the cushion block 27, and the aim of compressing the steel strip can be achieved. A pressing cylinder limit rod 28 is arranged below the pressing cylinder 22, so that the rotation angle of the pressing block 26 is ensured to be limited in a certain range under the transmission of the pressing cylinder 22.

A guide 16 is fixed on one side of the left partition 18, which is positioned on the base 4, and the steel belt 11 can be guided to accurately penetrate into the closed lock 14 in the process of threading through the guide 16 due to the small opening height of the closed lock.

The guide 16 is structured as shown in fig. 7, and has a main body 168, a rear wall 164 of the main body forming an L-shaped fixing notch 167, an arcuate middle guide chamber 162 below the main body 168, the middle guide chamber 162 extending forward to form an open arcuate front guide plate 161, the front guide plate 161 extending all the way between the passive feed roller 53 and the active feed roller 51, the middle guide chamber 162 extending rearward to form a closed generally flat rear guide chamber 163. The left partition 18 is provided with a fixing projection 183 corresponding to the L-shaped fixing notch 167, and the rear wall 164 of the guide 16 can be fixed to the fixing projection 183 by, for example, a bolt 165, and by such fixing projection 183, the guide 16 can be simultaneously pressed down and pressed toward the left partition, so that the fixation is more firm. And the left partition 18 is provided with an upper via hole 181 at a position corresponding to the rear guide chamber 163, and the rear guide chamber 163 can pass through the upper via hole 181.

The lock catch driving device 8 is provided with an upper push plate 82, a lower slide plate 84 with an opening is fixed below the upper push plate 82, and the upper push plate 82 and the lower slide plate 84 are fixedly connected and can be arranged in the slide rail 17 together in a sliding manner. The front width of the push plate 82 is gradually reduced to form a buckle inserting portion 83, and the width of the buckle inserting portion 83 is smaller than that of the lock catch 14, so that the buckle inserting portion 83 is conveniently inserted into the lock catch 14, and buckle taking is achieved. The tail of the upper push plate 82 is connected with a locking cylinder 87 through a transverse connecting block 81, and the cylinder 87 can drive the upper push plate 82 and the lower slide plate 84 to slide along the slide rail 17 through the transverse connecting block 81. The lower slide 84 may be positioned as close to the eye-splice 83 as possible to facilitate subsequent bending of the strip head, but the lower slide 84 cannot pass beyond the eye-splice 83, which would prevent the eye-splice 83 from performing the stripping action. An arc-shaped bending plate 85 facing the biting grip 19 is provided at the front end of the lower slide plate 84, and an opening 86 through which the steel belt 11 passes is formed between the arc-shaped bending plate 85 and the upper push plate 82.

The binding process of the novel binding machine will be described with reference to fig. 10A to 10H.

Fig. 10A mainly includes a latch magazine 9, a catch 19, a latch driving device 8, a right partition 21, and an electromagnet 20, and a portion not shown in the drawings can be referred to in the relevant views of fig. 1 to 9. Fig. 10A shows an initial state in which the steel strip 11 has not entered the baler, the push plate 82 is retracted to the initial position, the buckle part 83 is located outside the buckle magazine 9, one buckle 14 in the buckle magazine 9 falls off from the lower opening of the buckle magazine 9 onto the slide rail 17 under the action of gravity, and the electromagnet 20 is not energized, at this time, it has no magnetism. The bite grip 19 is in an initial zero position and the bite grip 19 is in an open state.

The system starts, as shown in fig. 10B, the cylinder 87 drives the push plate 82 to advance along the sliding rail 17 toward the gripping direction 19, the eye-splice portion 83 is inserted into the closed latch 14, the cylinder 87 continues to act, the push plate 82 continues to move forward, as shown in fig. 10C, after the eye-splice portion 83 moves between the gripping directions 19, the cylinder 87 stops acting, the push plate 82 advances to a proper position, and at this time, the push plate 82 is located below the latch repository 9 to cover the lower opening of the latch repository 9, and the latch 14 cannot fall off from the latch repository 9.

After the push plate 82 advances to a proper position, as shown in fig. 10D, the snap-in driving motor is started to drive the snap-in 19 from the open state to the half-engagement state, the opening of the snap-in 19 is gradually reduced, and the interval between the snap-in 19 is reduced until the snap-in 19 catches the lock catch 14, at this time, the snap-in 19 is in the half-engagement state, the snap-in 19 stops moving, and the lock catch 14 is captured by the snap-in 19 but is not locked.

After the latch 14 is captured, as shown in fig. 10E, the air cylinder 87 reversely pushes the push plate 82 to retract to the first retracted position where the eye-splice portion 83 is disengaged from the latch 14, the eye-splice portion 83 is retracted to a position substantially below the electromagnet 20, and the air cylinder 87 stops the reverse pushing. The upper push plate 82 in the first retracted position can guide the subsequently arriving steel strip 11 into the lower slide 84 and thus the steel strip 11 into the bottom guide 42.

As shown in fig. 10F, in the first retracted position, the electromagnet 20 is energized, the steel belt 11 is led out from the belt storage 13, the steel belt penetrates from the steel belt guiding device 1 to the steel belt pressing device 2, passes through the steel belt tensioning device 3, and enters the base 4, enters between the passive feeding roller 53 and the active feeding roller 51 under the guidance of the arc plate 18, the active feeding roller 51 rotates, the steel belt 11 is fed into the guide 16, passes through the guide 16 and enters the lock catch 14, the steel belt 11 then passes out from the lock catch 14, the electromagnet 20 attracts the head of the steel belt 11 penetrating from the lock catch 14 due to the action of the electromagnet 20, so that the head of the steel belt 11 can be basically attached to the lower surface of the push plate 82 to move forward, and the steel belt 11 passes through the opening 86 between the bending plate 85 and the push plate 82 and enters the lower slide plate 84 along with the movement of the steel belt 11.

Further, in order to facilitate the steel strip 11 entering the lower slide 84, the lower surface of the buckle portion 83 of the present utility model has an inclined slope 831, and the slope 831 may extend from the top end of the buckle portion 83 to the opening 86. Thus, the head of the steel belt 11 passing out of the lock catch 14 is easily entered into the lower slide 84 due to the guiding action of the inclined surface 831.

Referring to fig. 10G, after the steel belt 11 enters the lower slide plate 84, the electromagnet 20 is powered off, the steel belt enters the bottom guide path 42 along the lower slide plate 84, is guided by the inclined guide path 422, penetrates into the lock catch 14, and then the head of the steel belt penetrates out from the other side of the lock catch 14, because the electromagnet 20 is powered off and the upper steel belt is blocked, the head of the steel belt 11 moves towards the arc-shaped part of the bending plate 85 under the action of gravity, after the head of the steel belt 11 abuts against the bending plate 85, the steel belt 11 moves in place, the driving feeding wheel 51 stops rotating, the steel belt 11 stops, and then the steel belt between the lock catch 14 and the bending plate 85 can be reversely bent.

Further, after the steel strip 11 enters the lower slide plate 84, the air cylinder 87 further reversely pushes the upper push plate 82 to retract to the second retracted position where the eye-splice portion 83 is retracted to a position substantially below the right separator 21, and the air cylinder 87 stops the reverse pushing. The distance between the lock catch 14 and the bending plate 85 can be increased by retracting to the second retracted position, so that the length of the reversely bent steel belt is increased, more steel belts can be reversely bent, the bending part can bear larger tensile force in the subsequent binding process, and meanwhile, the longer reversely bent length is also beneficial to bending the steel belts.

After the steel belt 11 moves in place, the steel belt 11 can be pressed by the pressing device, as shown in fig. 10H, the air cylinder 87 pushes the upper push plate 82 and the lower slide plate 84 forward, that is, to move towards the lock catch 14, and during the movement, the bending plate 85 pushes the head of the steel belt to bend and then move towards the lower side of the lock catch 14, so that bending is realized, and the curved bending plate 85 is beneficial to the movement of the head of the steel belt 11 along the curved inner side of the bending plate 85, so as to facilitate bending. After the eye-splice 83 moves below the electromagnet 20, the push plate 82 stops and the bending is completed.

After the bending is completed, the upper push plate 82 and the lower slide plate 84 are kept still, and the bending plate 85 abuts against the bending part of the steel belt, so that the bending part can be further ensured not to be pulled out from the lock catch 14 in the binding process. The steel belt 11 is tensioned to bind the goods, for example, the steel belt 11 can be tensioned through the tensioning mechanism 5 in the base 4, and the steel belt 11 can bear large tensile force due to the bending part, so that the goods can be firmly bound. After the goods are bound, the snap-in driving motor is started again to drive the snap-in 19 to change from the half-in state to the full-in state, and the snap-in 19 bites the lock catch locking, so that the binding task is completed.

After the bundling task is completed, the steel belt 11 is cut off, the biting and gripping drive motor drives the biting and gripping 19 to open, the biting and gripping 19 returns to the open state from the full biting state, the cargoes are transported away from the bundling machine, the air cylinder 87 pushes the upper push plate 82 and the lower sliding plate 84 to return to the initial position shown in fig. 10A, after the upper push plate 82 leaves the lower opening of the latch repository 9, the next latch 14 falls onto the sliding rail 17 from the lower opening of the latch repository 9, and the bundling machine returns to the initial state shown in fig. 10A and is ready for next bundling.

Through the introduction, the novel bundling machine can realize automatic bundling of the closed lock catch, and the bundling is firm. As shown in fig. 11, the entire bundling process may generally include the steps of:

s100: the closure catch is pushed into the snapping mechanism by the catch drive.

In this process, the biting gripper 19 is opened, and after the lock catch is inserted through the insertion portion 83, the lock catch is pushed into the biting gripper 19.

S200: the snap-in mechanism captures the closure catch.

In this step, the opened bite grip 19 is shifted from the opened state to the half-bite state, thereby capturing the latch.

S300: the latch driving device is retracted to a first retracted position.

After withdrawal to the first withdrawn position the tab 83 is disengaged from the closure catch in preparation for a subsequent string.

S400: the strip is started to be led through the opening of the lock driving device after the strip passes through the closed lock catch.

This guiding is accomplished primarily by the guide 16 and the electromagnet 20, which guides the steel strip through the guide 16 accurately through the middle of the buckle, and the electromagnet 20 ensures that the steel strip head drops down after passing out of the buckle, so that the steel strip head can advance along the lower surface of the push plate on the buckle drive device, and thus through the opening 86 between the bending plate 85 and the push plate 82.

S500: after the steel belt winds the object to be bundled for a circle, the steel belt is guided to pass through the closing lock catch again.

After the steel strip has wound around the object to be bundled, the steel strip 11 enters the bottom guide 42, and the head of the steel strip 11 passes through the lock again by means of the inclined guide 422 in the bottom guide 42.

S600: and bending the head part of the steel belt penetrating out of the lock catch towards the lock catch direction to form a bending part.

This is achieved mainly by means of the bending plate 85, and the bending plate 85 is pushed to bend the head of the steel strip towards the locking direction.

S700: and locking the lock catch to be locked, and bundling is completed.

After the steel belt is tensioned, the snap-in driving motor is started again to drive the snap-in 19 to turn from the half-in state to the full-in state, and the snap-in 19 bites the lock catch locking, so that the bundling task is completed.
