A wire cutting device

Abstract

This invention relates to the field of freezer manufacturing technology, and specifically discloses a wire cutting device. It includes a wire feeding device and a cutting machine. The cutting machine comprises a first conveying mechanism, a straightening mechanism, a second conveying mechanism, a cutting mechanism, and a separating mechanism. The first and second conveying mechanisms have identical structures. The invention includes a cutting mechanism with a cutting blade mounted on a turntable. A limiting push block is also provided on one side of the cutting blade. After the cutting blade cuts, the subsequent wire pushes the cut wire, causing the separating mechanism to move away from the cutting base. Simultaneously, the limiting push block moves the limiting block in the separating mechanism downwards, thereby moving the pressure plate in the separating mechanism downwards and causing the rotating groove to rotate. The rotating groove separates from the fixed groove, and the cut wire falls off and quickly returns to its original position under the action of a return spring. Simultaneously, the entire separating mechanism also quickly returns to its original position under the action of a return spring, limiting the next section of wire to facilitate the next cut.

Description

Technical Field

[0001] This invention relates to the field of freezer manufacturing technology, and in particular to a wire cutting device. Background Technology

[0002] A wire mesh basket, as the name suggests, is a basket with a net. Wire mesh baskets have many uses, including in freezers. They are composed of several steel wires welded together in a crisscross pattern. Therefore, making a wire mesh basket first requires cutting the rolled-up steel wire into segments of the appropriate length. If this cutting is done manually, it is not only inefficient but also results in inconsistent cut lengths. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a time-saving and labor-saving wire cutting device that achieves accurate cutting.

[0004] This invention is achieved through the following technical solution:

[0005] A wire cutting device includes a wire feeding device and a cutting machine, characterized in that the cutting machine includes a worktable, on which a first conveying mechanism, a straightening mechanism, a second conveying mechanism, a cutting mechanism, and a separating mechanism are sequentially arranged, wherein the first conveying mechanism and the second conveying mechanism have the same structure; the cutting mechanism includes:

[0006] A hollow cutting base has an inlet hole at its inlet end, a cutting slit at its lower end, a turntable below the cutting slit, a cutting blade circumferentially arranged on the turntable, and a limiting push block on the side of the turntable facing the separation mechanism; the cutting base also has a notch at its outlet end.

[0007] The separation mechanism includes a sliding block with a steel wire channel located in the notch. A return spring is fixed on the sliding block, and a pressure plate is fixed on the top of the return spring. A limit block matching the limit push block is provided on the side of the pressure plate facing the turntable. During the rotation of the limit push block, the pressure plate will be moved down through the limit block.

[0008] The sliding block is fixed with a downward-facing groove. A rotating rod is provided above the groove via several fixed rings. The end of the rotating rod is provided with a pressure rod located below the pressure plate. A rotary spring is fitted on the rotating rod. One end of the rotary spring is located on the back of the groove, and the other end is located on the rotating rod. The rotating rod is connected to the groove via several arc-shaped rods. When the rotary spring is in its natural state, the groove and the groove are aligned to form a channel for the steel wire. Several positioning bolts are provided on the groove.

[0009] The fixed groove is provided with a return support rod, and a return spring is fixed between the return support rod and the cutting base;

[0010] It also includes a support frame with rolling wheels, and a frame on the fixing groove, the frame resting on the rolling wheels.

[0011] The wire feeding device includes a base, on which a rotating disk is provided. A conical rotating body is fixed at the center of the rotating disk, and a locking ring is placed on the rotating body.

[0012] The rotating body includes a central axis of rotation, a circular plate is fixed at the upper end of the central axis of rotation, and a plurality of inclined support rods are provided around the circular plate. The lower ends of the inclined support rods are fixed on the rotating disk.

[0013] The rotating disk includes a rotating cylinder that is rotatably connected to the base shaft. The rotating cylinder has a circumferential ring connected by at least three connecting rods. The rotation center shaft is fixedly connected to the rotating cylinder, and the lower end of the inclined support rod is fixed to the connecting rod.

[0014] The rotating disk is equipped with a counterweight by a rope.

[0015] Both the first conveying mechanism and the second conveying mechanism include: a conveying frame, wherein a fixed roller and an adjustable roller that can be adjusted up and down are provided in the conveying frame, with the fixed roller at the bottom and the adjustable roller at the top.

[0016] The fixed roller has an annular groove, and the adjusting roller has an annular protrusion that matches the annular groove.

[0017] The straightening mechanism includes a rectangular rotating frame with several slotted plates and rotating cylinders at both ends.

[0018] A sleeve is provided between two adjacent slot plates.

[0019] The beneficial effects of this invention are:

[0020] The present invention is equipped with a rotating wire feeding device, on which the coiled steel wire is placed. Driven by two conveying mechanisms in the subsequent process, the wire is gradually released, and the steel wire is continuously transported to the wire cutting equipment for cutting.

[0021] The present invention also includes a straightening mechanism, in which a rotating frame can rotate. During the rotation, a small portion of the bent or crooked parts are straightened, which facilitates subsequent cutting.

[0022] The invention also includes a cutting mechanism. A cutting blade is mounted on a turntable in the cutting mechanism, and a limiting push block is provided on one side of the cutting blade. After the cutting blade cuts, the subsequent steel wire pushes the cut steel wire, causing the sliding block of the separation mechanism to slide at the notch of the cutting base. At the same time, the limiting push block drives the limiting block in the separation mechanism to move down, thereby driving the pressure plate in the separation mechanism to move down. This causes the pressure rod, rotating rod, and arc rod to drive the rotating groove to rotate, causing the rotating groove to separate from the fixed groove. The cut steel wire falls off and quickly returns to its original position under the action of the return spring. At the same time, the entire separation mechanism also quickly returns to its original position under the action of the return spring, limiting the next section of steel wire to facilitate the next cutting.

[0023] The present invention not only has high cutting efficiency through the above process, but also produces steel wires of uniform length with high precision. Attached Figure Description

[0051] The attached figures illustrate specific embodiments of the present invention.

[0052] To better understand the above-mentioned objects, features, and advantages of the present invention, the following...

[0053] The present invention will be further described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0054] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0055] like Figures 1 to 20 As shown, this type of wire cutting equipment includes a wire feeding device 1 and a cutting machine. The cutting machine includes a worktable 405, on which a first conveying mechanism 2, a straightening mechanism 3, a second conveying mechanism 02, a cutting mechanism 4, and a separating mechanism 5 are sequentially arranged. The first conveying mechanism 2 and the second conveying mechanism 02 have the same structure. Specifically:

[0056] The wire feeding device 1 includes a base 101, which can be cylindrical and relatively heavy, so that it cannot be pulled away from its original position during the pulling of the wire coil. A rotating disk 102 is installed on the base 101. The rotating disk 102 includes a rotating cylinder 103 that is rotatably connected to the base 101. The installation of the rotating cylinder 103 is existing technology and will not be described in detail. There is a ring 104 around the rotating cylinder 103. Several connecting rods 105 are fixedly installed around the rotating cylinder 103. The connecting rods 105 are radially distributed around the rotating cylinder 103. The outer ends of the connecting rods 105 are fixed to the ring 104. The number of connecting rods 105 is at least three, such as four, five, or six.

[0057] A rotating body is mounted on the rotating disk 102. The rotating body includes:

[0058] The rotating cylinder 103 has a fixed rotation center shaft 106, such as Figure 2As shown, the rotating center shaft 106 can be integrally manufactured with the shaft rotating cylinder 103, that is, the shaft rotating cylinder 103 can be part of the lower end of the rotating center shaft 106. A circular plate 107 is fixedly installed at the top of the rotating center shaft 106. An inclined support rod 108 is installed circumferentially on the circular plate 107. The lower end of the inclined support rod 108 is fixed on the connecting rod 105. The upper end of the inclined support rod 108 can be arc-shaped. All the inclined support rods 108 form a cone shape. The number of inclined support rods 108 can be less than the number of connecting rods 105, but not less than three.

[0059] In actual operation, the rotating body rotates synchronously with the rotating disk 102.

[0060] A locking ring 109 is placed on the rotating body. The preferred embodiment of the locking ring 109 is rectangular or elliptical. After the wire roll is placed on the rotating body, the locking ring 109 is fitted onto the rotating body to limit the movement of the wire roll.

[0061] A counterweight 110 is connected to the rotating disk 102 by a rope. The counterweight 110 is dragged on the ground and moves along the ground as the rotating disk 102 rotates during use, thus balancing the wire feeding device 1.

[0062] The first conveying mechanism 2 and the second conveying mechanism 02 have the same structure. They can be the conveying structures in the prior art, or they can be the following structures:

[0063] like Figure 1 , Figure 4 , Figure 5 , Figure 19 and Figure 20 As shown, a conveying frame is fixed on a workbench 405. The conveying frame includes two upright plates 201 and a top plate 202. The two upright plates 201 are perpendicular to the traveling direction of the steel wire 6. Each of the two upright plates 201 has holes for the steel wire 6 to pass through. Two mounting plates 203 are installed between the two upright plates 201, one at the front and one at the back. A fixed roller 204 is installed on the two mounting plates 203. A slider 205 is located between the two upright plates 201, above the fixed roller 204. An adjusting roller 206 is installed on the lower surface of the slider 205. An annular groove 2041 is opened on the fixed roller 204. An annular protrusion 2061 can be set on the adjusting roller 206. The annular protrusion 2061 matches the annular groove 2041 to jointly compress and convey the steel wire 6.

[0064] A spring 207 is fixedly installed on the slider 205, and a screw 208 is threadedly connected to the top plate 202. The lower end of the screw 208 is rotatably connected to the spring 207. The screw 208 can drive the slider 205 and the adjusting roller 206 to move up and down. The range of this movement does not need to be large, just enough for the steel wire 6 to pass through.

[0065] The straightening mechanism 3 is located between the first conveying mechanism 2 and the second conveying mechanism 02. It can use existing technology or have the following structure:

[0066] A rectangular rotating frame 301 is provided, with the length of the rotating frame 301 being the same as the length of the steel wire 6. A rotating cylinder 302 is integrally formed at both ends of the rotating frame 301. Several slotted plates 303 are installed between the two long sides of the rotating frame 301. The slots of the slotted plates 303 can clamp the steel wire 6. A sleeve 304 is also installed between two adjacent slotted plates 303. The sleeve 304 can also be fixed on the two long sides of the rotating frame 301.

[0067] Two rotating cylinders 302 are mounted on the worktable 405 via bearing seats 305.

[0068] The rotating drum 302 is driven to rotate by a motor via a transmission belt 306.

[0069] The next process after the second conveying mechanism 02 is a cutting structure, and the cutting mechanism 4 includes:

[0070] A hollow cutting base 401 has an inlet hole 4011 on one side adjacent to the second conveying mechanism 02 for the steel wire 6 to enter, and a notch 4012 on the other side. The lower end of the cutting base 401 is a cutting slit 4013. A turntable 402 is installed below the cutting slit 4013. A cutting blade 403 is installed circumferentially on the turntable 402. The cutting blade 403 is preferably replaceable. The cutting blade 403 extends into the cutting base 401 and can cut the steel wire 6. The turntable 402 can be connected to a rotating shaft. The rotating shaft and the output end of another motor are connected by two meshing bevel gears. This is existing technology and will not be described in detail. The motor drives the turntable 402 to rotate. The motor can also drive two fixed rollers 204 to rotate at the same time. The two fixed rollers 204 can also be driven to rotate synchronously by a third motor.

[0071] A limiting push block 404 is fixedly installed on the side of the cutting blade 403 facing the notch 4012.

[0072] The gap 4012 is T-shaped.

[0073] The worktable 405 is also a hollow structure, and all motors (not shown in the figure) are installed inside the worktable 405.

[0074] The separation mechanism 5 includes a sliding block 501 located within the notch 4012. The sliding block 501 has a steel wire channel and can move along the length of the steel wire 6 within the notch 4012.

[0075] A return spring 502 is fixedly mounted on the upper surface of the sliding block 501. A pressure plate 503 is fixedly mounted on the upper end of the return spring 502. A limiting block 504 is provided on the side of the pressure plate 503 facing the turntable 402. The limiting block 504 is positioned low, such as... Figure 10 and Figure 11 As shown in the figure, the turntable 402 rotates clockwise. During the upward rotation of the limit push block 404, it does not come into contact with the limit block 504. When the limit push block 404 rotates to the highest point and begins to fall, it begins to come into contact with the limit block 504. During the downward rotation of the limit push block 404, the limit push block 404 pushes the limit block 504 to move downward, thereby causing the pressure plate 503 to move downward.

[0076] The limit push block 404 can be cylindrical.

[0077] The design of the limiting block 504 needs to avoid the steel wire 6. Therefore, a connecting plate 5031 can be set on the pressure plate 503 first, and then the limiting block 504 can be connected to the lower end of the connecting plate 5031 at a position lower than the steel wire 6.

[0078] A fixed groove 505 is integrally connected to the outer side of the sliding block 501. The opening of the fixed groove 505 faces downward, which is equivalent to a long tube cut in half. Several fixed rings 506 are installed on the fixed groove 505. A rotating rod 507 passes through the fixed rings 506. The rotating rod 507 is located diagonally above the fixed groove 505. A rotary spring 508 is sleeved on the rotating rod 507. One end of the rotary spring 508 rests on the back of the fixed groove 505, and the other end is fixed to the rotating rod 507. A pressure rod 509 is fixed to the end of the rotating rod 507 near the sliding block 501. The pressure rod 509 is L-shaped, and its end is located below the pressure plate 503. When the pressure plate 503 moves down, it drives the pressure rod 509 to rotate, thereby driving the rotating rod 507 to rotate.

[0079] Several arc-shaped rods 510 are fixedly installed on the rotating rod 507. The aforementioned arc-shaped rods 510 are all fixed on a rotating groove 511. When the pressure plate 503 is at its highest point, that is, when the rotary spring 508 is in a relaxed state, the rotating groove 511 and the fixed groove 505 fit together to form a channel that allows the steel wire 6 to pass through.

[0080] like Figure 1 and Figure 17 As shown, the fixing groove 505 is also threaded with several positioning bolts 512. The positioning bolts 512 block a small part of the forward passage of the steel wire 6, preventing it from continuing to move forward, thus playing a positioning role.

[0081] All the holes and channels through which the steel wire 6 can pass are located on a single axis to facilitate the smooth and unimpeded passage of the steel wire 6.

[0082] like Figure 14As shown, a return support rod 513 is fixedly provided on the fixed groove 505. The return support rod 513 and the fixed groove 505 form a cross structure. Return springs 514 are fixed between the two ends of the return support rod and the cutting base 401. The separation mechanism 5 is driven to return through the return springs 514.

[0083] There is also a support frame 515, which can be placed on the ground; a roller 516 is installed on the support frame 515; a frame 517 is installed at the end of the fixed groove 505 away from the sliding block 501, the frame 517 rests on the roller 516 and can slide on the roller 516, the roller 516 plays a supporting role.

[0084] The work process is as follows:

[0085] The steel wire is wound onto the rotating body, and the locking ring 109 is placed on the rotating body. The end of the steel wire 6 is passed sequentially through the rotating cylinder 302 and groove plate 303 and sleeve 304 of the first conveying mechanism 2, the straightening mechanism 3, the second conveying mechanism 02, the cutting base 401, and the sliding block 501, and enters the channel formed by the fixed groove 505 and the rotating groove 511. The appropriate positioning bolt 512 is selected for positioning, and the positions of the two adjusting rollers 206 are adjusted by the screw 208 to ensure that they can convey the steel wire 6 normally. All motors are started, and the first conveying mechanism 2 and the second conveying mechanism 02 convey the steel wire 6. If there is a position that is not straight enough, it is straightened by the rotating groove plate 303 at the straightening mechanism 3. The turntable 402 rotates, driving the cutting blade 403 to rotate, cutting the steel wire 6 and continuing to rotate. The subsequent steel wire 6 pushes the cut steel wire 6 forward, driving the sliding block 501 to move forward. Simultaneously, as the limiting push block 404 on the cutting blade 403 rotates, it causes the limiting block 504 to move downwards, and the pressure plate 503 to move downwards. This causes the rotating rod 507 to rotate via the pressure rod 509. The rotating rod 507 then causes the rotating groove 511 to rotate via the arc rod 510. The cut wire 6 loses control of the rotating groove 511. Since the contact area between the cut wire 6 and the positioning bolt 512 is very small, the cut wire 6 falls off under the push of the subsequent wire 6. At this time, the limiting block 504 and the limiting push block 404 also separate. The sliding block 501 returns to its original position under the action of the return spring 514, the pressure plate 503 resets under the action of the reset spring 502, and the rotating rod 507 rotates back to its original position under the action of the rotation spring 508. The subsequent wire 6 continues to be pushed to the positioning bolt 512, and the cutting blade 403 rotates back to cut. The above steps are repeated to form continuous cutting.
