Abstract

This invention discloses a bidirectional straightening mechanism for a wire coil support frame, belonging to the technical field of wire coil support frames. The invention includes two symmetrically arranged sliding rails on the upper surface of a support beam, push rod assemblies symmetrically installed within the sliding rails, a linkage assembly that links the two push rod assemblies within the same sliding rail to move synchronously relative to each other or in opposite directions, a drive assembly that drives the push rod assemblies within the two sliding rails to move synchronously, and a locking assembly that partially retracts or extends the push rod assemblies from the sliding rails. When the drive assembly drives the two vertical push rods to move to both sides, under the pressure of the transverse rollers, the vertical push rods are completely retracted into the sliding rails, without affecting the lifting and placement of the wire coil on the upper surface of the support beam.

Then, the continuous relative movement of the vertical push rods achieves convenient straightening and clamping of the wire coil.

Description

Technical Field

[0001] This invention relates to the field of wire coil shelving technology, and more specifically to a bidirectional straightening mechanism for a wire coil shelving. Background Technology

[0002] A wire coil holder is a rack for holding wire coils. The applicant has an existing patent: a wire coil holder (patent number: CN114147678B), comprising a base, a support column, and a supporting beam; the front of the supporting beam has a front stop that blocks the front of the wire coil, and the rear of the supporting beam has a movable stop that blocks the rear of the wire coil. The movable stop is configured to move according to different wire coil lengths, allowing the rear of the wire coil to rest against the movable stop. Because the front stop protrudes from the upper surface of the support column, it causes inconvenience for lifting and placing the wire coil; simultaneously, the movable stop at the rear requires manual operation to change its position, which is inconvenient. To solve the above problems, this invention provides a bidirectional straightening mechanism for a wire coil holder. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the present invention aims to provide a bidirectional straightening mechanism for a wire coil support frame. When the drive assembly drives the two vertical push rods to move to both sides, under the pressure of the transverse rollers, the vertical push rods are completely retracted into the slide rail, without affecting the upper surface of the support beam for lifting and placing the wire coil. When the drive assembly drives the two vertical push rods to move continuously towards each other, under the action of the torsion spring, the vertical push rods are in a vertical state and attached to the side of the vertical block of the L-shaped slider. Then, the continuous relative movement of the vertical push rods achieves convenient straightening and clamping of the wire coil, thus solving the technical problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a bidirectional straightening mechanism for a wire coil support frame, including two symmetrically arranged sliding rails on the upper surface of a support beam, push rod assemblies symmetrically installed in the sliding rails, a linkage assembly that links the two push rod assemblies in the same sliding rail to move synchronously relative to each other or in opposite directions, a drive assembly that drives the push rod assemblies in the two sliding rails to move synchronously, and a locking assembly that partially houses or extends the push rod assemblies from the sliding rails; the push rod assembly includes an L-shaped slider and a vertical push rod slidably installed in the sliding rail. The vertical push rod is connected to the upper surface of the horizontal block of the L-shaped slider via a hinge. The torsion spring is sleeved on the outside of the hinge, and its two arms are fixed to the side of the vertical push rod and the upper surface of the horizontal block of the L-shaped slider, respectively. The openings of the two L-shaped sliders are opposite each other in the same slide rail. When the locking and releasing assembly acts on the vertical push rod, the torsion spring is compressed, causing the vertical push rod to be retracted into the slide rail. When the locking and releasing assembly does not act on the vertical push rod, under the action of the torsion spring, the vertical push rod is in a vertical state and attached to the side of the vertical block of the L-shaped slider.

[0005] Preferably, the linkage component is a bidirectional threaded screw rotatably installed between the two ends of the slide rail. The two sides of the bidirectional threaded screw are respectively threaded to two push rod assemblies in the same slide rail. When the bidirectional threaded screw rotates, the two push rod assemblies in the same slide rail move synchronously relative to each other or in opposite directions. When the two push rod assemblies in the same slide rail move relative to each other, the two sides of the wire coil are straightened and tightened and fixed. When the two push rod assemblies in the same slide rail move in opposite directions, the wire coil is released.

[0006] Preferably, the bidirectional threaded screw is threadedly connected to the horizontal block of the L-shaped slider, and the top of the vertical block of the L-shaped slider is lower than the upper surface of the support beam; this ensures that when the vertical push rod retracts into the slide rail, the entire push rod assembly is located inside the slide rail, which does not affect the placement of the wire coil on the upper surface of the support beam, making it convenient and practical.

[0007] Preferably, the locking assembly consists of symmetrically installed transverse rollers within the slide rail, with the two transverse rollers positioned close to the ends of the slide rail. The height of the transverse rollers is higher than the top of the vertical block of the L-shaped slider. When the drive assembly drives the vertical push rod within the same slide rail to move to both sides, the vertical push rod is squeezed by the transverse rollers, causing it to rotate around the horizontal block of the L-shaped slider until it is completely retracted into the slide rail, without affecting the upper surface of the support beam for lifting and placing the wire coil. When the drive assembly drives the vertical push rod within the same slide rail to move continuously towards each other, after the vertical push rod no longer contacts the transverse rollers, under the action of the torsion spring, the vertical push rod is in a vertical state and adheres to the side of the vertical block of the L-shaped slider. Then, the continuous relative movement of the vertical push rod achieves convenient straightening and clamping of the wire coil.

[0008] Preferably, the drive assembly includes a drive motor, a drive horizontal shaft, bevel gear A, and bevel gear B. Drive slots are formed on opposite sides of the support beam. The drive horizontal shaft communicates with the corresponding slide rail. The drive horizontal shaft is rotatably mounted between the bottom surfaces of the two drive slots, with both ends extending into the corresponding drive slots. Two bevel gears A are coaxially fixedly mounted on the drive horizontal shaft, with bevel gear A located at the connection between the drive horizontal shaft and the slide rail. Bevel gear B is coaxially fixedly mounted at the middle position of the bidirectional threaded screw, with bevel gear B located at the connection between the drive horizontal shaft and the slide rail. Bevel gear A meshes with the corresponding bevel gear B. The output end of the drive motor is connected to one end of the drive horizontal shaft, and the drive motor is fixedly mounted on the side of the support beam. When the drive motor drives the drive horizontal shaft to rotate, the drive horizontal shaft drives the two bidirectional threaded screws to rotate via bevel gears A and B, achieving synchronous movement of the four push rod assemblies within the two slide rails, which is efficient and convenient.

[0009] Preferably, the L-shaped slider has symmetrically provided limiting strips on both sides of the horizontal block, and the slide rail has symmetrically provided strip-shaped limiting slide grooves on both sides of the slide rail, with the limiting strips slidably installed in the strip-shaped limiting slide grooves; thus ensuring the stability of the L-shaped slider when sliding in the slide rail.

[0010] Preferably, a connecting groove is provided at the top of the vertical push rod, and an extension push rod for extending the length is installed in the connecting groove; by providing a connecting groove at the top of the vertical push rod and installing an extension push rod in the connecting groove, the height of the vertical push rod is extended, providing a better straightening and support effect for the wire coil.

[0011] The beneficial effects of this invention are as follows:

[0012] 1. When the drive assembly drives the two vertical push rods to move to both sides, under the pressure of the transverse roller, the vertical push rods are completely retracted into the slide rail, without affecting the upper surface of the support beam for placing the wire coil; when the drive assembly drives the two vertical push rods to move towards each other continuously, after the vertical push rods are no longer in contact with the transverse roller, under the action of the torsion spring, the vertical push rods are in a vertical state and attached to the side of the vertical block of the L-shaped slider, and then the vertical push rods continue to move relative to each other to achieve convenient straightening and clamping of the wire coil.

[0013] 2. The present invention provides a better straightening and support effect for the wire coil by opening a connecting groove at the top of the vertical push rod and installing an extension push rod in the connecting groove. Attached Figure Description

Detailed Implementation

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: As Figures 1 to 8 As shown, the present invention provides a bidirectional straightening mechanism for a wire coil support frame, including two symmetrically arranged sliding rails 2 on the upper surface of a support beam 1, with the sliding rails 2 extending along the length of the support beam 1 and symmetrically installed in the sliding rails 2; a linkage component that links the two push rod components in the same sliding rail 2 to move synchronously relative to each other or in opposite directions; a drive component that drives the push rod components in the two sliding rails 2 to move synchronously; and a locking component that partially stores or extends the push rod components from the sliding rails 2.

[0026] Please see Figure 3 , Figure 5 and Figure 8 As shown, the push rod assembly includes an L-shaped slider 3, a vertical push rod 4, and a torsion spring 41, which are slidably installed in the slide rail 2. The vertical push rod 4 is connected to the upper surface of the horizontal block of the L-shaped slider 3 via a hinge. The torsion spring 41 is sleeved on the outside of the hinge, and the two arms of the torsion spring 41 are respectively fixed to the side of the vertical push rod 4 and the upper surface of the horizontal block of the L-shaped slider 3. The openings of the two L-shaped sliders 3 in the same slide rail 2 are opposite each other, which ensures that when the vertical push rod 4 pushes the wire coil straight, the vertical block of the L-shaped slider 3 provides stable support for the vertical push rod 4, so that the vertical push rod 4 remains vertical.

[0027] Please see Figures 2 to 4 as well as Figure 7 As shown, the linkage component is a bidirectional threaded screw 5 rotatably installed between the two ends of the slide rail 2. The two sides of the bidirectional threaded screw 5 are respectively threaded to two push rod assemblies within the same slide rail 2. When the bidirectional threaded screw 5 rotates, the two push rod assemblies within the same slide rail 2 move synchronously relative to each other or in opposite directions. When the two push rod assemblies move relative to each other, they straighten and tighten the two sides of the wire coil. When the two push rod assemblies move in opposite directions, they release the wire coil. More specifically, the bidirectional threaded screw 5 is threaded to the horizontal block of the L-shaped slider 3. The top of the vertical block of the L-shaped slider 3 is lower than the upper surface of the support beam 1, ensuring that when the vertical push rod 4 retracts into the slide rail 2, the entire push rod assembly is located inside the slide rail 2, without affecting the lifting and placement of the wire coil on the upper surface of the support beam 1, making it convenient and practical. More specifically, the L-shaped slider 3 has symmetrical limit strips 31 on both sides of the horizontal block, and the slide rail 2 has symmetrical strip-shaped limit slide grooves 21 on both sides of the slide rail 2. The limit strips 31 are slidably installed in the strip-shaped limit slide grooves 21 to ensure the stability of the L-shaped slider 3 when it slides in the slide rail 2.

[0028] Please see Figure 1 , Figure 2 as well as Figure 6 As shown, when the locking assembly acts on the vertical push rod 4, the torsion spring 41 is compressed, causing the vertical push rod 4 to retract into the slide rail 2. When the locking assembly does not act on the vertical push rod 4, under the elastic force of the torsion spring 41, the vertical push rod 4 is in a vertical position and attached to the side of the vertical block of the L-shaped slider 3, ensuring stable support when the vertical push rod 4 straightens the wire coil. More specifically, the locking assembly consists of two transverse rollers 6 symmetrically installed in the slide rail 2, with the two transverse rollers 6 corresponding to the two ends of the slide rail 2, and the height of the transverse rollers 6 is higher than the top of the vertical block of the L-shaped slider 3. When the drive assembly drives the vertical push rod 4 in the same slide rail 2 to move to both sides, the vertical push rod 4 is squeezed by the horizontal roller 6, causing the vertical push rod 4 to rotate around the horizontal block of the L-shaped slider 3 until the vertical push rod 4 is completely retracted into the slide rail 2, without affecting the upper surface of the support beam 1 for lifting and placing the wire coil; when the drive assembly drives the vertical push rod 4 in the same slide rail 2 to move in opposite directions, after the vertical push rod 4 and the horizontal roller 6 no longer contact each other, under the elastic force of the torsion spring 41, the vertical push rod 4 is in a vertical state attached to the side of the vertical block of the L-shaped slider 3, and then the vertical push rod 4 continues to move relative to each other to achieve convenient straightening and clamping of the wire coil.

[0029] Please see Figures 1 to 4 as well as Figure 7As shown, the drive assembly includes a drive motor, a drive horizontal shaft 7, bevel gears A71 and B72. Drive slots 73 are formed on opposite sides of the support beam 1. The drive horizontal shaft 7 is connected to the corresponding slide rail 2. The drive horizontal shaft 7 is rotatably mounted between the bottom surfaces of the two drive slots 73, with both ends extending into the corresponding drive slots 73. Two bevel gears A71 are coaxially fixedly mounted on the drive horizontal shaft 7, with A71 located at the connection point between the drive horizontal shaft 7 and the slide rail 2. A bevel gear B72 is coaxially fixedly mounted in the middle of the bidirectional threaded screw 5, with B72 located at the connection point between the drive horizontal shaft 7 and the slide rail 2. Bevel gears A71 and B72 mesh with each other. The output end of the drive motor is connected to one end of the drive horizontal shaft 7, and the drive motor is fixedly mounted on the side of the support beam 1. The drive motor is not shown in the figure. When the drive motor drives the drive horizontal shaft 7 to rotate, the drive horizontal shaft 7 drives the two bidirectional threaded screws 5 to rotate through bevel gear A71 and bevel gear B72, so as to realize the synchronous movement of the four push rod assemblies in the two slide rails 2, which is efficient and convenient.

[0030] Example 2: Please refer to Figure 4 and Figure 5 As shown, while retaining all the technical features of the specific embodiment one, a connecting groove 42 is opened at the top of the vertical push rod 4, and an extension push rod for extending the length is installed in the connecting groove 42. The extension push rod is not shown in the figure. By opening the connecting groove 42 at the top of the vertical push rod 4 and installing the extension push rod in the connecting groove 42, the height of the vertical push rod 4 is extended, providing a better straightening and support effect for the wire coil.

[0031] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
