Description

Technical Field

[0001] The utility model relates to the technical field of wire and cable cutting equipment, in particular to a knife holder for a computer cutting machine. Background Art

[0002] Wires and cables are wire products used to transmit electricity, magnetic energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which are generally composed of one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] During the use of wires and cables, since they need to be connected to other electrical appliances, they are often unwound to facilitate connection. Existing computer wire cutting machines use an air pump to power the cutter head to press down and cut during cutting. For example, patent number CN207787573U, titled "A Wire Cutting Machine with a Movable Blade Holder," utilizes an eccentric wheel to cut the cable. However, the blade wears out after a long period of cutting, and since the blade is hidden in the blade holder, the blade holder needs to be removed for replacement, which is a cumbersome operation. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a knife holder for a computer cutting machine.

[0005] According to the technical solution provided in the embodiment of the present application, a knife holder for a computer cutting machine includes a conveying part connected to the cutting machine and conveying cables, a cutting table arranged on the conveying part, and a cutting part for cutting cables. The cutting part is connected to the cutting machine through a bracket, and the cutting blade on the cutting part is rotated on a vertical plane by a rotating motor. When the cutting blade rotates to the cutting table, it cuts the cable conveyed by the conveying part. When the cutting blade is away from the cutting table, it is suspended on the outside of the knife holder for the cutting machine to facilitate the replacement of the cutting blade.

[0006] Furthermore, the conveying part includes a vertical plate and conveying rollers. Several conveying rollers are arranged on the side end surface of the vertical plate. The conveying rollers are rotated on the vertical plane by a transmission motor to realize the conveyance of the cable.

[0007] Furthermore, the cutting table is a horizontal plate, and a cutting hole for the cutting blade to pass through is provided on the cutting table, so as to facilitate the passing of the cutting blade.

[0008] Furthermore, a cable cutting and temporary fixing device is provided on the conveying part, which includes a transmission component fixed on the cutting blade and a temporary fixing component provided on the vertical plate. When the cutting blade rotates to cut, the transmission component acts on the temporary fixing component to temporarily fix the cable.

[0009] Furthermore, the transmission component is a spherical transmission bead, and the temporary fixing component includes a fixing plate and a temporary fixing ball. The fixing plate is vertically arranged on the vertical plate. The two temporary fixing balls are fixedly connected by a connecting rod. The connecting rod moves through the arc-shaped hole on the fixing plate. The upper end surface of the connecting rod is fixedly connected to the fixing plate by a compression spring to facilitate the rebound of the temporary fixing ball.

[0010] Furthermore, a staggered hole is provided on the lower side of the arc hole so that the temporary fixing component and the transmission component are staggered, which is used to place the connecting rod when the temporary fixing component and the transmission component are staggered, so that the transmission component continues to rotate with the cutting blade.

[0011] Furthermore, the upper end surface of the cutting table and the conveying end surface of the conveying roller are located on the same horizontal plane, thereby achieving continuity in cable conveying.

[0012] Furthermore, the cutting blade is fixed to the cutting turntable of the cutting part by bolts, which is convenient for disassembly.

[0013] To sum up, the beneficial effects of the present application are as follows: the device of the present application utilizes a rotating blade, and when the blade is not in use, the blade can be rotated out of the blade holder to change the blade; when the rotating blade cuts the cable, the transmission component on the blade is used to act on the temporary fixing component on the conveying part to achieve temporary fixation of the cable, thereby reducing the probability of damage to the cable surface when cutting the cable after the blade is damaged, and also improving the cutting efficiency.

DETAILED DESCRIPTION

[0019] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0020] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Computer cutting machine with knife holder, such as Figure 1 and Figure 2 As shown, the cutting machine tool holder includes a conveying portion 1 connected to the cutting machine and conveying cables, a cutting table 2 provided on the conveying portion 1, and a cutting portion 3 for cutting cables.

[0022] The cutting turntable 33 on the cutting part 3 is fixed to the bracket 4 through a bearing. A cutting blade 31 is fixed to one end of the cutting turntable 33 by a bolt. The cutting blade 31 protrudes from the side end surface of the cutting turntable 33. The cutting turntable 33 is rotated on the vertical plane by a rotating motor 32 fixed to the bracket 4. When the cutting turntable 33 rotates, the cutting blade 31 will be driven to rotate.

[0023] The conveying portion 1 includes a vertical plate 11 and a conveying roller 12 provided on the left end surface of the vertical plate 11. The conveying roller 12 includes an upper conveying wheel and a lower conveying wheel. The upper conveying wheel and the lower conveying wheel rotate in opposite directions. When a cable is placed between the upper conveying wheel and the lower conveying wheel, the cable can be conveyed.

[0024] A horizontally placed cutting table 2 is provided at the rear end of the left end surface of the vertical plate 11. A cutting hole 21 is provided on the cutting table 2 and is located on the same vertical plane as the cutting blade 31, so that the cutting blade 31 can pass through the cutting table 2 when rotating in the vertical plane.

[0025] like Figure 2 and Figure 3 As shown, a spherical transmission component 6 is fixedly provided on the front and rear ends of the cutting blade 31, and a vertically placed temporary fixing component 5 is correspondingly provided on the left end face of the vertical plate 11. A certain distance is provided between the fixing plate 51 on the temporary fixing component 5 and the upper end face of the cutting table 2 to facilitate the passage of the cable. When the transmission component 6 rotates with the cutting blade 31 and reaches the temporary fixing component 5, it will push the temporary fixing ball 52 to move in the arc-shaped hole 511 until the temporary fixing ball 52 presses the cable on the cutting table 2, so that the cable is temporarily fixed;

[0026] like Figure 3As shown, the two temporary balls 52 are fixedly connected by a horizontally placed connecting rod 53, and the connecting rod 53 moves through the arc-shaped hole 511, and the upper end surface of the connecting rod 53 is fixedly connected to the top surface of the arc-shaped hole 511 through a compression spring 54. An offset hole 512 communicating with the arc-shaped hole 511 is provided at the lower right side of the arc-shaped hole 511.

[0027] When in use, the cable to be cut is placed on the conveying roller 12, so that the cable-type conveying part 1 is conveyed to the cutting table 2, and then the rotation speed of the conveying roller 12 and the rotation speed of the cutting blade 31 are determined according to the speed of the cable conveyed by the conveying roller 12, the rotation speed of the cutting blade 31 and the length of the cable to be cut.

[0028] When the cable to be cut is transported to the cutting table 2 by the conveying roller 12, due to the start of the rotating motor 32, the cutting turntable 33 rotates clockwise with the cutting blade 31. When the cutting blade 31 rotates to the cutting table 2, the transmission component 6 provided on the front and rear ends of the cutting blade 31 will overlap with the temporary fixing ball 52 on the temporary fixing component 5. As the transmission component 6 continues to rotate clockwise, the temporary fixing ball 52 will continue to be pressed down until the temporary fixing ball 52 presses the cable onto the cutting table 2. Since the temporary fixing components 5 are provided on the front and rear sides of the cutting hole 21, the front and rear sides of the cable cutting part are suppressed when cutting the cable. At this time, the cutting blade 31 directly cuts the cable. The blade 31 continues to rotate clockwise. Since the transmission component 6 is spherical, the transmission component 6 continues to press down the temporary fixing ball 52. Since it has reached the bottom of the arc-shaped hole 511 at this time, in order to realize the rotation of the transmission component 6, the temporary fixing ball 52 will slide to the dislocation hole 512 due to the connecting rod 53, so that the transmission component 6 and the temporary fixing ball 52 are dislocated. The transmission component 6 and the cutting blade 31 continue to make circular motion. Since the upper end of the dislocation hole 512 is an upwardly inclined arc shape, the temporary fixing ball 52 will return to its previous state together with the connecting rod 53 under the influence of the restoring force of the compression spring 54, waiting for the next time the cutting blade 31 cuts the cable, it will be driven by the transmission component 6 to temporarily suppress the cable, thereby improving the cable cutting efficiency.

[0029] When the cutting blade 31 needs to be replaced, the cutting blade 31 is rotated to the left end of the bracket 4. At this time, the bolts can be directly removed to replace the cutting blade 31.

[0030] In this solution, a safety cover can be provided on the outside of the cutting turntable 33 to prevent the cutting blade 31 from flying out and causing danger.

[0031] The above description is merely an illustration of the preferred embodiments of the present application and the technical principles employed. The scope of the invention herein is not limited to the technical solutions formed by the specific combination of the aforementioned technical features, but also encompasses other technical solutions formed by any combination of the aforementioned technical features or their equivalents without departing from the inventive concept. For example, a technical solution formed by replacing the aforementioned features with (but not limited to) technical features with similar functions disclosed in this application.
