[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1, reference Figures 1 to 6 , which is the first embodiment of the present utility model, provides a clamping and forming mechanism that can increase the clamping force on the rods and prevent the rods from becoming loose during the bundling process.

[0037] Specifically, it includes a support component 100, which includes a support frame 101. The support frame 101 includes a top plate 101a, a support column 101b and a low plate 101c. The top plate 101a and the low plate 101c are hollowed out so that the clamping component 200 and the power component 300 can move therebetween; the support column 101b is supported between the four corners of the top plate 101a and the low plate 101c to form a storage space for the support component 100.

[0038] The support component 100 further includes two hinged seats 102 , which are symmetrically arranged and are respectively welded or bolted to the lower plate 101 c inside the support frame 101 .

[0039] The clamping component 200 includes a first clamping component 201 and a second clamping component 202 . The first clamping component 201 and the second clamping component 202 are symmetrically arranged in a clamp shape.

[0040] The first clamping assembly 201 includes a first clamping component 201a and a connecting column 201b. Two first clamping components 201a are stacked, and the connecting column 201b welds and secures the two first clamping components 201a together.

[0041] The height of the connecting column 201 b is slightly greater than the thickness of the second clamping assembly 202 , so that the second clamping assembly 202 can pass through the gap between the two first clamping parts 201 a and move relative to the first clamping parts 201 a .

[0042] Furthermore, the first clamping component 201a is formed by shearing from steel plate; it includes a first clamping claw 201a-1 and a first transmission arm 201a-2. The first clamping claw 201a-1 is hook-shaped, and the first transmission arm 201a-2 is straight. The first transmission arm 201a-2 is laterally connected to the end of the first clamping claw 201a-1, and the angle between the first transmission arm 201a-2 and the side wall of the first clamping claw 201a-1 is 80±5 degrees. The other end of the first transmission arm 201a-2 is hinged to one of the hinge seats 102. Connecting posts 201b are welded to the center of the first clamping claw 201a-1 and the lower portion of the first transmission arm 201a-2, respectively, to enhance the connection strength between the two first clamping components 201a.

[0043] Preferably, the second clamping assembly 202 includes a second clamping claw 202a and a second transmission arm 202b, the second clamping claw 202a is hook-shaped, the second transmission arm 202b is straight-plate-shaped, the second transmission arm 202b is connected to the side of the end of the second clamping claw 202a, the angle between the second transmission arm 202b and the side wall of the second clamping claw 202a is 80±5 degrees, and the other end of the second transmission arm 202b is hinged to the other hinge seat 102.

[0044] It should be noted that when the top ends of the first transmission arm 201a-2 and the second transmission arm 202b are brought together and the bottom ends rotate along the hinge seat 102 respectively, the first clamping claw 201a-1 and the second clamping claw 202a gradually separate, so that the rod is transmitted into between the first clamping claw 201a-1 and the second clamping claw 202a; when the first transmission arm 201a-2 and the second transmission arm 202b are separated, the first clamping claw 201a-1 and the second clamping claw 202a are enclosed into a ring to tighten the bundling of the rod; the extension distance of the cylinder telescopic rod can be adjusted according to the bundling diameter of the wire. The greater the extension distance, the smaller the inner diameter of the ring enclosed by the first clamping claw 201a-1 and the second clamping claw 202a, so as to adapt to the clamping bundling shape of small-diameter wires.

[0045] The power component 300 is arranged on the lower side of the clamping component 200, and includes a cylinder assembly 302 and a connecting assembly 301 arranged on the cylinder assembly 302; the connecting assembly 301 can transmit the power of the cylinder to the clamping component 200.

[0046] It should be noted that the cylinder assembly 302 includes a cylinder 302a and a fixed block 302b. The cylinder 302a provides power for the movement of the clamping component 200, and the fixed block 302b is bolted to the top end of the telescopic rod of the cylinder 302a.

[0047] Furthermore, the connecting assembly 301 includes a first connecting rod 301a and a second connecting rod 301b.

[0048] Among them, there are four first connecting rods 301a, and the four first connecting rods 301a are respectively arranged on both sides of the two first clamping parts 201a, and one end of each first connecting rod 301a is hinged to the connection between the first clamping claw 201a-1 and the first transmission arm 201a-2; there are two second connecting rods 301b, and the two second connecting rods 301b are respectively arranged on both sides of the second clamping assembly 202, and one end of each second connecting rod 301b is hinged to the connection between the second clamping claw 202a and the second transmission arm 202b.

[0049] The connecting assembly 301 also includes a connecting shaft 301c, which is welded to the top surface of the fixed block 302b. The end of the first connecting rod 301a away from the first clamping component 201a is hinged to the connecting shaft 301c, and the end of the second connecting rod 301b away from the second clamping assembly 202 is hinged to the connecting shaft 301c, that is, the first connecting rod 301a can rotate relative to the first clamping component 201a and relative to the connecting shaft 301c, and the second connecting rod 301b can rotate relative to the second clamping assembly 202 and relative to the connecting shaft 301c.

[0050] When in use, in the initial state, the telescopic rod of the oil cylinder is in the retracted state, and the connecting shaft 301c drives the first connecting rod 301a and the second connecting rod 301b to be in the first position. Figure 1Since the other end of the first link 301a is hinged to the first clamping component 201a, and the other end of the second link 301b is hinged to the second clamping component 202, the lengths of the first transmission arm 201a-2 and the second transmission arm 202b are fixed, and the ends of the first transmission arm 201a-2 and the second transmission arm 202b are respectively hinged to the hinge seat 102, when the ends of the first link 301a and the second link 301b hinged to the connecting shaft 301c move downward, the other ends of the first link 301a and the second link 301b The first and second transmission arms 201a-2, 202b move closer together, thereby driving the first and second transmission arms 201a-2, 202b closer together. Furthermore, due to the connection between the first clamping jaw 201a-1 and the first transmission arm 201a-2, and the connection between the second clamping jaw 202a and the second transmission arm 202b, when the first transmission arm 201a-2 and the second transmission arm 202b move closer together, the first clamping jaw 201a-1 and the second clamping jaw 202a move away from each other, i.e., the first and second clamping jaws 201a-1, 202a are in an open position. By adjusting the extension length of the oil cylinder, the angle at which the first and second clamping jaws 201a-1, 202a open can be controlled. In this embodiment, a preferred angle is when the distance between the front ends of the first and second clamping jaws 201a-1, 202a is equal to the distance between the top ends of the first guide roller 404 and the top end of the second guide roller 405.

[0051] After the bar is delivered to the clamping component 200, the telescopic rod of the oil cylinder extends to lift the first connecting rod 301a and the second connecting rod 301b to the second position. Figure 2 The other ends of the first connecting rod 301a and the second connecting rod 301b will move away from each other, thereby driving the first transmission arm 201a-2 and the second transmission arm 202b to move away from each other, pulling the first clamping claw 201a-1 and the second clamping claw 202a closer and enclosing them in a ring shape, so that the rod is clamped between the first clamping claw 201a-1 and the second clamping claw 202a, so as to facilitate the bundling of the rods.

[0052] It should be noted that the above-mentioned hinged connection method is not limited to a specific hinged connection method as long as it can achieve the hinged effect.

[0053] Example 2, reference Figures 1 to 7 This is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a bar bundling device, which solves the problem of continuous transportation and bundling of bars.

[0054] Specifically, it includes a guide component 400, which includes a first support frame 401, a second support frame 402 and a horizontal support frame 403. The horizontal support frame 403 is bolted to the top beam 101a, and the first support frame 401 and the second support frame 402 are symmetrically arranged on both sides of the horizontal support frame 403 and are bolted to the horizontal support frame 403.

[0055] The cross-sections of the first support frame 401 and the second support frame 402 are set to be right triangles, the inclined surfaces of the first support frame 401 and the second support frame 402 are opposite to each other, and the first support frame 401 and the second support frame 402 and the horizontal support frame 403 form an inverted trapezoidal baling channel.

[0056] Furthermore, the guide component 400 also includes a first guide roller 404, a second guide roller 405 and a horizontal guide roller 406. The first guide roller 404 is installed on the inclined surface of the first support frame 401, the second guide roller 405 is installed on the inclined surface of the second support frame 402, and the horizontal guide roller 406 is installed on the top surface of the horizontal support frame 403; the first guide roller 404, the second guide roller 405 and the horizontal guide roller 406 are based on the relative positions of the first support frame 401, the second support frame 402 and the horizontal support frame 403 to form an inverted trapezoidal roller conveyor.

[0057] The rest of the structure is the same as that of Example 1.

[0058] During use, the rod is transferred to between the first clamping jaw 201a-1 and the second clamping jaw 202a via the guide component 400. Due to the position setting of the first guide roller 404, the second guide roller 405 and the horizontal guide roller 406, the rod is initially gathered so that the first clamping jaw 201a-1 and the second clamping jaw 202a can clamp the rod.

[0059] In summary, the setting of the clamping component 200 and the power component 300 increases the clamping force on the rods, avoiding the loosening of the rods after bundling due to loose bundling, and is suitable for rods of different bundle diameters. At the same time, the setting of the guide component 400 effectively reduces the probability of steel jamming in the bundling channel, so that the rods are initially gathered, thereby improving the efficiency of steel bundling.

[0060] This device is also suitable for modifying existing bar balers. Since the clamping component 200 and the guide component 400 are independently arranged, they can be used as long as the heights of the clamping component 200 and the guide component 400 are consistent during installation. Furthermore, the power component 300 adopts multi-link synchronous movement, and only a single cylinder is needed to achieve the clamping effect of this device, and the installation, modification and use costs are relatively low.

[0061] Example 3, reference Figure 8 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a limiting component for the clamping component of the bar bundling device.

[0062] It includes a limiting component 500, specifically a limiting plate 501 and a connecting plate 502. The limiting plate 501 is set to be triangular, and the top corner of the limiting plate 501 is connected to the connecting plate 502; the connecting plate 502 is bolted to the top plate 101a.

[0063] Furthermore, four limiting components 500 are provided, two limiting components 500 are respectively installed on both sides of the clamping component 200, and the limiting components 500 on each side are installed symmetrically. The provision of the limiting components 500 effectively prevents the clamping component 200 from shaking during movement.

[0064] The remaining structures are the same as those in the above embodiment.
