Description

Technical Field

[0001] This utility model relates to an auxiliary device for a bar baling machine, belonging to the metallurgical machinery industry. Background Technology

[0002] When a bar baling machine pulls out the wire during baling, to prevent the baling wire from scattering and piling up behind the equipment, posing a safety hazard to the equipment and the site, a wire storage device must be installed above the wire feeding device of the baling machine to restrain the pulled-out baling wire within the device. For example... Figure 1 ,like Figure 2 As shown, a typical wire storage device currently includes a frame body 11, a pressing roller 12, and a fixed guide roller 13. The frame body 11 is connected to the baling machine 15 via a pin 14. The pressing roller 12 is mounted on the frame body, and the fixed guide roller 13 is mounted on the baling machine. Its working principle is as follows: before the baling machine threads the wire, the frame body is flipped over via the pin, and the pressing roller is moved away from the fixed guide roller (e.g., ...). Figure 1 (As shown), then the strapping wire is threaded into the strapping machine from above the fixed guide wheel, and finally the machine body is flipped down and the pressure wheel presses down on the strapping wire (as shown). Figure 2 As shown in the diagram, when the strapping machine pulls the wire back, the strapping wire is constrained within the frame. The disadvantages of this structure are: 1. Workers need to lift the frame before threading the wire, which is inconvenient for the strapping machine; 2. The pressure rollers and fixed guide rollers constrain the strapping wire into a "~" shape, resulting in significant bending of the wire, often causing wire jamming during feeding; 3. Because the frame needs to be manually rotated during threading, the frame must be lightweight, meaning its sheet metal is usually very thin. This causes the wire to wobble and rub against the frame's sheet metal during pulling, eventually wearing through and becoming unusable. Summary of the Invention

[0003] The problem this invention aims to solve is to provide a wire storage device for a bar baling machine. This device allows for the switching between wire threading and pressing via a flipping swing arm, greatly increasing convenience. Simultaneously, it presses the baling wire into an "M" shape, minimizing wire bending and ensuring smooth, uninterrupted wire feeding.

[0004] This utility model discloses a wire storage device for bar packing wire, which includes a frame, two guide roller assemblies, three wear-resistant guide roller assemblies, and a wire pressing assembly. The frame is welded together from two front and rear panels and a bottom plate, with a gap between the two panels. The three wear-resistant guide roller assemblies are located at the upper left, upper right, and lower left of the frame. The two guide roller assemblies are located in the lower middle part of the frame and are arranged left and right. The wire pressing assembly is located in the upper middle part of the two guide roller assemblies and has two states: located inside the frame and located outside the frame.

[0005] Furthermore, the wire pressing assembly includes a swing arm, a wire pressing wheel assembly, a hand-tightening nut, a mounting base, and a stud; the frame has an annular groove above the middle of the left and right wire wheel assemblies, and a stud and a mounting base are welded above and below the annular groove, respectively. The lower part of the swing arm is hinged to the mounting base, the middle part is connected to the wire pressing wheel assembly, and the upper part is connected to or separated from the stud. The hand-tightening nut is screwed into the stud.

[0006] Furthermore, the swing arm is L-shaped: the junction of the long and short sides is located inside the connecting seat and is hinged to the connecting seat by a connecting pin; a U-shaped groove is provided at the top of the long side; and the middle of the long side is connected to the pressure wheel assembly.

[0007] Furthermore, the pressure roller assembly includes a pressure roller, bearing I, connecting shaft I, and nut I. The connecting shaft I passes through the hole in the frame and mates with the hole in the middle of the swing arm. The threaded section in front of it is screwed with nut I. The bearing I is mounted on the mounting section inside the frame. The pressure roller is sleeved on the bearing I. The surface of the pressure roller is provided with a V-groove.

[0008] Furthermore, the guide wheel assembly includes a guide wheel, bearing II, connecting shaft II, and nut II. The front and rear ends of the connecting shaft II are engaged with holes on the front and rear panels of the frame and locked by the nut II. The bearing II is mounted on the middle section, and the guide wheel is on the bearing II and located in the gap between the front and rear panels.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] from Figure 3 , Figure 6 As can be seen, the present invention discloses a wire storage device for a bar baling machine, which includes a frame 1, two guide wheel assemblies 2, three wear-resistant guide wheel assemblies 6, and a wire pressing assembly; the frame 1 is welded together from two front and rear panels and a bottom plate, with a gap between the two panels; the three wear-resistant guide wheel assemblies 6 are located at the upper left, upper right, and lower left of the frame 1; the two guide wheel assemblies 2 are located in the lower middle part of the frame 1 and are arranged left and right; the wire pressing assembly is located at the upper middle part of the two guide wheel assemblies 2, and has two states: located inside the frame 1 and located outside the frame 1.

[0024] The working principle of this utility model wire storage device is as follows: before the baling machine needs to thread the wire, the wire pressing component is first removed from the frame 1, and then the baling wire is threaded into the baling machine through the gap on the bottom plate of the frame 1 and the wear-resistant guide wheel component 6 on the lower right, above the two guide wheel components 2. Then, the wire pressing component is positioned inside the frame 1 to press the baling wire. In this way, when the baling machine pulls the wire back, under the action of the wire pressing component 4, the baling wire is stored in the frame 1 through the three wear-resistant guide wheel components 6.

[0025] The advantages of this utility model wire storage device are: 1. The wire pressing component can easily thread the packing wire after leaving the frame; the clamping component can easily clamp the packing wire after entering the frame; 2. When winding the wire, the three anti-wear guide wheel components at the upper left, upper right, and lower left form three constraint points, which can prevent the packing wire from shaking and rubbing in the frame, thus enhancing the durability of the frame; 3. The frame, which does not need to be lifted, does not require a lightweight design, thus improving its own durability.

[0026] Example 2

[0027] from Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 It can be seen that the wire storage device of this utility model includes a wire pressing assembly comprising a swing arm 3, a wire pressing wheel assembly 4, a hand-tightening nut 5, a mounting base 7, and a stud 8; the frame 1 has an annular groove at the upper position between the two left and right wire wheel assemblies 2, and the stud 8 and the mounting base 7 are welded to the upper and lower positions of the annular groove, respectively. The lower part of the swing arm 3 is hinged to the mounting base 7, the middle part is connected to the wire pressing wheel assembly 4, and the upper part is connected to or separated from the stud 8. The hand-tightening nut 5 is screwed into the stud 8.

[0028] The present invention relates to a wire storage device: Before threading the wire, the hand-tightening nut 5 on the stud 8 is removed, and the lower part of the swing arm 3 is pressed down. The swing arm 3 drives the wire pressing wheel assembly 4 to swing outward away from the frame 1, i.e., outside the frame 1. At this time, the wire is threaded. After the wire is threaded, the lower part of the swing arm 3 is loosened, and the swing arm 3 drives the wire pressing wheel 4 to swing inward into the frame 1. The hand-tightening nut 5 is screwed onto the stud 8 so that the swing arm 3 is pressed tightly onto the frame 1, thereby causing the wire pressing wheel assembly 4 to press the packing wire.

[0029] This invention allows the wire pressing wheel assembly 4 to be conveniently positioned outside the frame 1 for wire threading or inside the frame 1 for wire pressing by swinging the swing arm 3. Compared to the existing method where the wire threading or pressing can only be achieved by flipping the frame body, this invention makes wire threading very convenient.

[0030] Example 3

[0031] from Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As can be seen, the wire storage device of this utility model has the following features: the swing arm 3 is L-shaped; the junction of the long and short sides is located inside the connecting seat 7 and is hinged to the connecting seat 7 by the connecting pin 9; a U-shaped groove is provided at the top of the long side; and the middle of the long side is connected to the wire pressing wheel assembly 4.

[0032] The swing arm 3 swings via the connecting pin 9, which in turn drives the pressure roller assembly 4 to swing, thus allowing the pressure roller assembly 4 to have two states: inside the frame 1 and outside the frame 1. The U-shaped groove allows for easy separation or connection between the swing arm 3 and the stud 8.

[0033] Example 4

[0034] from Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 It can be seen that the wire storage device of this utility model includes a pressure wheel assembly 4, a pressure wheel 41, a bearing I 42, a connecting shaft I 43, and a nut I 44. The connecting shaft I 43 passes through the hole in the frame 1 and engages with the hole in the middle of the swing arm 3. The threaded section in front of it is screwed with the nut I 44. The bearing I 42 is mounted on the mounting section inside the frame 1. The pressure wheel 41 is sleeved on the bearing I 42. The surface of the pressure wheel 41 is provided with a V-shaped groove.

[0035] The clamping roller 41 is fixedly connected to the swing arm 3 via connecting shaft I 43 and nut I 44. When the swing arm 3 swings back and forth, the clamping roller 41 swings back and forth accordingly to separate from or enter the machine base, thereby realizing threading or clamping the packing line. When the packing machine needs to thread the line, the lower part of the swing arm 3 is pressed down, causing the clamping roller assembly 4 to move forward away from the machine base. At this time, the packing line is threaded from above the two guide rollers 2 through the gap in the bottom plate of the frame 1 and the wear-resistant guide roller assembly 6 on the lower right into the packing machine. Figure 6 As shown; then loosen the swing arm 3, allowing the pressure roller assembly 4 to move backward into the frame 1. At this point, the pressure roller 41 is positioned precisely in the gap between the front and rear panels. By tightening the hand-tightening nut 5, the swing arm 3 is pressed against the front panel of the frame 1, thereby causing the pressure roller 41 to press the packing line, as shown. Figure 3 As shown. Because the pressure roller 41 is slightly higher than the guide roller assemblies 2 at both ends, the packing line is pressed into an "m" shape, and the bending of the packing line is small, so the packing machine feeds the line smoothly without jamming.

[0036] Example 5

[0037] from Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As can be seen, the wire storage device of this utility model includes a guide wheel assembly 2 comprising a guide wheel 21, a bearing II 22, a connecting shaft II 23, and a nut II 24. The front and rear ends of the connecting shaft II 23 are engaged with holes on the front and rear panels of the frame 1 and locked by the nut II 24. The bearing II 22 is mounted on the middle section. The guide wheel 21 is sleeved on the bearing II 22 and located in the gap between the front and rear panels. The surface of the guide wheel 21 is provided with a V-shaped groove.

[0038] The packing line is fed into the packing machine along the V-groove on the surface of the guide wheel 21.

[0039] Example 6

[0040] from Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As can be seen, the wire storage device of this utility model: the anti-wear guide wheel assembly 6 includes a connecting frame 61, a connecting shaft Ⅲ 62, and an anti-wear guide wheel 63. The connecting frame 61 is connected to the frame 1. The front and rear sections of the connecting shaft Ⅲ 62 are fitted with the holes of the front and rear supports of the connecting frame 61. The anti-wear guide wheel 63 is installed on the middle section of the connecting shaft Ⅲ 62 through a bearing. The surface of the anti-wear guide wheel 63 is provided with a V-shaped groove.

[0041] When the wire is being wound up, the three anti-wear guide roller assemblies at the upper left, upper right, and lower left form three constraint points, which can prevent the packing wire from shaking and rubbing in the frame and enhance the durability of the frame; among them, the anti-wear guide roller assembly 6 at the lower left also plays a guiding role when threading the wire.

[0042] like Figure 10 As shown, the wire storage device of this utility model is fixed above the wire feeding device of the baling machine by a frame. The advantages of this wire storage device are: 1. When threading and pressing the wire, only the swing arm needs to be flipped, without flipping the frame, which greatly increases convenience; 2. The retracted baling wire is constrained within the frame of the wire storage device by three anti-wear guide wheels, which reduces friction and greatly improves the durability of the frame; 3. The pressing wheel and the two guide wheels on the left and right cooperate to press the baling wire into an "m" shape, with less bending of the baling wire, so the wire feeding is smooth and does not jam.
