Description

Technical Field

[0001] The present technical solution relates to the technical field of baling machines, and in particular to a rocker arm structure of a baling machine hot cutter head. Background Art

[0002] A baler is a type of packaging equipment. Its main function is to use strapping tape to bundle products or packages to reinforce the packaged items. Balers are widely used in logistics, packaging, manufacturing and other industries to package various items into a whole for easy transportation and storage.

[0003] For example, the Chinese patent publication number CN205525131U discloses a hot-gluing mechanism for a baling machine, which includes a hot-gluing slide plate that can perform telescopic movement, a hot-gluing knife head for hot-gluing arranged below the hot-gluing slide plate, a rocker arm that drives the hot-gluing knife head to move forward and backward, a hot-gluing top knife that can slide up and down arranged at the bottom of the hot-gluing knife head, a connecting seat is hinged at the top of the rocker arm, the hot-gluing knife head is fixed on the connecting seat, and a limit plate that prevents the connecting seat from turning downward is arranged on the rocker arm. When the hot-gluing top knife moves upward, it can move upward with the hot-gluing knife head, and a return spring that drives the connecting seat to contact the limit plate is arranged between the connecting seat and the rocker arm, and the return spring quickly pulls the connecting seat back to the bottom, and the hot-gluing knife head and the connecting seat also turn downward due to gravity to ensure the hot-gluing effect.

[0004] The above-mentioned hot-gluing mechanism for the baling machine has a relatively large rocker arm structure of the existing hot-gluing head, which results in a relatively long force arm from the supporting point between the hot-gluing head and the hot-gluing slide board to the fulcrum, making the hot-gluing head prone to breakage or deformation, which needs to be improved. Summary of the invention

[0005] In order to improve the problem that the hot cutter head is prone to breakage or deformation during hot gluing, the present technical solution provides a rocker arm structure for the hot cutter head of a baling machine.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A rocker arm structure for a hot cutter head of a baling machine comprises a frame, a hot-jointing abutment plate and a hot-jointing top knife arranged on the frame, the frame is provided with a rocker arm, the rocker arm is hinged to the frame, the rocker arm is provided with a hot cutter head, the rocker arm is used to drive the hot cutter head to move below the hot-jointing abutment plate, the hot-jointing top knife is slidably connected to the frame, the hot-joining top knife slides relative to the hot cutter head for hot-joining cooperation, the hot cutter head is provided with an elastic reset member, the rocker arm is provided with a mounting plate, the elastic reset member is connected between the mounting plate and the hot cutter head, the elastic force of the elastic reset member makes the hot cutter head tend to approach the mounting plate, and the elastic reset member is used to reset the hot cutter head.

[0008] The cam is then moved back to the position where the cutter head is pressed against the mounting plate, and the cam is moved back to the position where the cutter head is pressed against the mounting plate, thereby reducing the risk of the cutter head being broken or deformed.

[0009] Preferably, the mounting plate has a butt plate, the butt plate extends below the ironing head, the butt plate is used for the ironing head to butt against, the ironing head is provided with a fixing plate, the fixing plate is located between the ironing head and the connecting plate, the fixing plate is provided with a bolt structure, and the fixing plate is connected to the ironing head through the bolt structure;

[0010] The fixing plate is provided with a connecting portion, the connecting portion protrudes from a side of the fixing plate close to the connecting plate, the connecting plate is provided with a connecting hole, the connecting portion passes through the connecting hole, and the elastic reset member is connected between the connecting portion and the mounting plate.

[0011] Through the above technical scheme, a fixing plate is additionally installed under the ironing head, and the fixing plate is tightly connected to the ironing head through a bolt structure. The connection method between the fixing plate and the ironing head is simple and the connection is firm. The mounting plate has a supporting plate and extends to the bottom of the ironing head to form a supporting surface. The position of the fixing plate is arranged opposite to the supporting plate, and the connecting part on the fixing plate passes through the connecting hole of the supporting plate accordingly. One end of the elastic reset member is connected to the mounting plate and fixed, and the other end is connected to the connecting part. Based on the relatively fixed position of the mounting plate after connection, the elastic force directly acts on the ironing head through the connecting part, and the ironing head can stably rest on the supporting plate through the fixing plate to achieve pressure dispersion, thereby improving the stability of the ironing head.

[0012] Preferably, the abutment plate is provided with a clearance hole, the position of the clearance hole corresponds to the bolt structure, and the clearance hole is used for allowing the bolt structure to pass through.

[0013] Through the above technical solution, the clearance holes are opened on the abutment plate and their positions correspond one-to-one to the bolt structures. The shape and size of the clearance holes are adapted to the bolt structures, so that when the fixing plate abuts against the abutment plate, the bolt structure can be aligned with the clearance holes and embedded, and the bolt heads of the bolt structures can be built into the clearance holes. The clearance holes provide clearance for the bolt structures, so that the positioning accuracy and stability of the hot cutter head are better.

[0014] Preferably, the rocker arm is provided with a reciprocating drive assembly, which includes a rotating shaft, a cam mechanism and an elastic member. The cam mechanism is arranged between the rotating shaft and the rocker arm, and the elastic member is connected between the frame and the rocker arm. The elastic force of the elastic member makes the rocker arm tend to approach the frame, and the rotating shaft drives the cam mechanism and the elastic member to cooperate to enable the rocker arm to achieve reciprocating swing.

[0015] Through the above technical solution, the control driving device drives the rotating shaft to rotate, and the rotating shaft can cooperate with the cam mechanism when it rotates. The cam mechanism as a transmission member can act on the rocker arm at the same time, so that the rocker arm overcomes the elastic force of the elastic member and rotates. At this time, the rocker arm drives the ironing knife head away from the ironing contact plate to achieve mutual separation. After the pushing effect of the cam mechanism on the rocker arm ends, the elastic force of the elastic member will pull the rocker arm to rotate in the opposite direction, so that the ironing knife head can approach the ironing contact plate again, thereby achieving the reciprocating swing effect of the rocker arm.

[0016] Preferably, the cam mechanism comprises a rotating cam arranged on a rotating shaft and a bearing wheel arranged on a rocker arm, the rotating cam is arranged coaxially with the rotating shaft, and the rotating shaft is used to drive the rotating cam to rotate;

[0017] The bearing wheel is hinged to the rocker arm, and the hinge axis of the bearing wheel is parallel to the rotation axis of the rotating cam. When the rotating cam rotates, the rotating cam and the bearing wheel come into conflict with each other to realize the rotation of the rocker arm.

[0018] Through the above technical scheme, the cam mechanism is mainly composed of a rotating cam arranged on the rotating shaft and a bearing wheel arranged on the rocker arm. The rotating cam is coaxially fixed on the rotating shaft. The rotation of the rotating shaft drives the rotating cam to rotate synchronously along the axis of the rotating shaft. The position of the rotating cam is relative to the bearing wheel so that the rotating cam and the bearing wheel conflict with each other when rotating. The rotating cam can push the bearing wheel to realize the rotation of the rocker arm. By controlling the rotation speed and angle of the rotating cam, the swing amplitude and frequency of the rocker arm can be accurately controlled. When the bearing wheel and the rotating cam conflict with each other, they can rotate synchronously along the hinge axis, avoiding the rotating cam and the bearing wheel from always conflicting and rubbing on the same plane of the bearing wheel when they contact, thereby reducing the resistance caused by friction, improving the movement efficiency of the cam mechanism and reducing the influence of friction.

[0019] Preferably, the rotating cam has a cam surface and a concave wheel surface, and the cam surface and the concave wheel surface are distributed circumferentially along the circumferential side of the rotating cam. When the rotating cam rotates until the cam surface is opposite to the bearing wheel, the cam surface pushes the bearing wheel to overcome the elastic force of the elastic member to realize the rocker arm rotating away. When the concave wheel surface is opposite to the bearing wheel, the rocker arm rotates close to the concave wheel surface under the action of the elastic member.

[0020] Through the above technical scheme, the cam surface and the concave wheel surface circumferentially arranged on the circumferential side of the rotating cam can both face the end surface towards the bearing wheel, so that when the rotating cam rotates in the same direction, the end surface opposite to the bearing wheel switches alternately between the cam surface and the concave wheel surface. When the cam surface is opposite to the bearing wheel, the cam surface protrudes toward the bearing wheel to achieve the effect of pushing the rocker arm. When the concave wheel surface is opposite to the bearing wheel, the concave wheel surface is recessed relative to the cam surface. The distance between the concave wheel surface and the bearing wheel is enlarged, so that the rocker arm is close to the rotating cam, thereby improving precise control and ensuring that the rocker arm swings quickly and smoothly.

[0021] Preferably, the ironing knife head has an ironing and bonding convex plate, which is located at one end of the ironing knife head close to the ironing abutment plate, and the ironing and bonding convex plate is inclined downward away from the ironing knife head. When the ironing and bonding convex plate is used for ironing, the ironing and bonding convex plate is against between the ironing abutment plate and the ironing top knife.

[0022] Through the above technical scheme, the hot-stitching convex plate of the ironing knife head serves as the main part of the ironing operation. The hot-stitching convex plate extends in the direction of the ironing abutment plate. The hot-stitching convex plate has a certain inclination angle relative to the ironing knife head, so that when the ironing top knife pushes the ironing head upward to flip, based on the downward inclination of the hot-stitching convex plate, the hot-stitching convex plate is parallelly adapted to the ironing top knife after the ironing head rotates. The upper and lower end surfaces of the hot-stitching convex plate form a stable contact surface with the ironing top knife and the ironing abutment plate, thereby enhancing the accuracy of the ironing operation of the strap, further extending the service life of the ironing knife head and improving the stability of use.

[0023] Preferably, the ironing head is provided with a heating component, the ironing head is provided with a placement groove, the placement groove is located on a side of the ironing head close to the fixed plate, the heating component is installed in the placement groove, the heating component is fixed to the ironing head by a bolt structure, the heating component is connected to a power connection line, and the ironing head is also provided with a heat insulation sheet, the heat insulation sheet is abutted between the heating component and the fixed plate for heat insulation of the heating component.

[0024] Through the above technical solution, the heating component is installed in the mounting groove of the ironing head to achieve positioning, and then fixed by a bolt structure passing through the heating component. The power connection line is connected to the heating plate to provide it with a load voltage. Based on the resistance composed of the heating wire in the heating component, the heating wire obtains electrical energy for heating to meet the needs of ironing. A heat insulation sheet is added between the heating component and the fixed plate. The heat insulation sheet can effectively isolate the heat generated by the heating component and prevent the heat from being transferred to the fixed plate and other components, thereby improving the overall stability and safety in high temperature environments.

[0025] Preferably, the power connection line is provided with a wiring arrangement structure, which includes a positioning block 1 and a positioning block 2, wherein the positioning block 1 is arranged on the abutment plate, and the positioning block 2 is located on the side of the positioning block 1 away from the abutment plate, and a wire channel is formed between the positioning block 1 and the positioning block 2, and the wire channel is for the power connection line to pass through, and the positioning block 1 and the positioning block 2 are connected by bolts and pressed against both sides of the power connection line for positioning.

[0026] Through the above technical solution, the positioning block 1 in the wiring structure is fixed on the abutment plate, and the positioning block 2 is abutted against the position of the corresponding positioning block 1, so that the wire channel guides the power connection line to be arranged according to a predetermined path. The positioning block 2 and the positioning block 1 are fixed by bolts so that they are tightly pressed against the two sides of the same position of the power connection line. The large number of power connection lines provides a good positioning effect, optimizes the arrangement of the power connection lines, and improves safety and neatness.

[0027] Preferably, the mounting plate is provided with a wire-hiding plate, and the wire-hiding plate is used to shield the power connection line.

[0028] Through the above technical solution, the hidden wire plate is covered on the power connection line, thereby preventing the power connection line from being directly exposed to the outside, improving the neatness of the overall appearance, reducing potential safety hazards, and enhancing the safety of the power connection line.

[0029] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:

[0030] 1. The technical solution is to hinge a rocker arm on the frame, and the rocker arm drives the ironing knife head to move to the bottom of the ironing plate and cooperate with the ironing knife to perform the ironing operation. After the ironing is completed, the ironing knife retreats, and the elastic reset member of the ironing knife head pulls the ironing knife head against the mounting plate to reset. The rotation fulcrum of the ironing knife head for the ironing operation is closer to the ironing plate, shortening the length of the force arm, thereby reducing the torque applied to the ironing knife head during the ironing process, reducing wear to extend the service life, and improving the stability of the ironing knife head;

[0031] 2. The technical solution is to provide a reciprocating drive assembly on the rocker arm, and the reciprocating drive assembly includes a rotating shaft, a cam mechanism and an elastic member. The cam mechanism serves as a transmission member. The rotating shaft drives the rocker arm to overcome the elastic force of the elastic member and rotates through the cam mechanism. The ironing knife head is separated from the ironing contact plate. After the cam mechanism stops pushing the rocker arm, the elastic member pulls the rocker arm to rotate in the opposite direction, thereby achieving the reciprocating swing effect of the rocker arm.

The positioning block 222 is close to the positioning block 1 221 so that a wire channel 23 is formed. The wire channel 23 is for the power connection line 20 to pass through. The positioning block 222 is passed through by bolts so that the positioning block 222 and the positioning block 1 221 are pressed against the upper and lower sides of the power connection line 20 to achieve positioning. At the same time, the bolts pass through the fixed plate 9 so that the positioning block 1 221 is bolted to the fixed plate 9.

[0055] The specific working process of this program is as follows:

[0056] The present technical solution is that a hot knife head 5 is installed on the rocker arm 4, and the reciprocating drive assembly 14 drives the rocker arm 4 to swing back and forth. When the rocker arm 4 drives the hot knife head 5 to move to the bottom of the hot-joining plate 2, the hot-joining top knife 3 slides toward the hot knife head 5 until it pushes the hot-joining convex plate 17, overcomes the elastic force of the elastic reset member 6 to move the hot-joining convex plate 17 and the hot-joining abutment plate 2 to cooperate with the hot-joining belt. When the hot-joining is completed, the hot-joining top knife 3 retreats and releases the hot knife head 5. The elastic force of the elastic reset member 6 pulls the hot knife head 5 to reset it to abut against the abutment plate 8. When hot-joining, only the hot knife head 5 needs to be rotated, and the structural foundation is optimized and adjusted. The rotation fulcrum of the hot-joining operation of the hot-joining head 5 is closer to the hot-joining abutment plate 2, shortening the length of the force arm, thereby reducing the torque applied to the hot knife head 5 during the hot-joining process, reducing the risk of breakage or deformation of the hot-joining head 5, reducing wear to extend the service life, and improving the stability of the hot-joining head 5.
