Description

Technical Field

[0001] This utility model relates to the technical field of wood cutting equipment, specifically to a large arc cutting machine for wooden cable reels. Background Technology

[0002] Wooden cable reels are wooden load-bearing tools used for winding, transporting, and storing cables. Their core features are stable load-bearing capacity, moderate cost, and compatibility with various cable specifications. A cable reel consists of a central cylinder and two side panels. For larger cable reels, due to the larger required panel dimensions, several sector-shaped panels are typically used. To increase the contact area between the sector-shaped panels and the cylinder, thereby increasing bonding strength, matching bevels are cut at the edges where the sector-shaped panels and the cylinder connect.

[0003] In existing technologies, band saws are mostly used for cutting wood. Band saws can cut various shapes according to the movement of the wood planks, but these shapes are usually simple planar shapes, and it is not easy to cut the bevel of the connecting end of the fan-shaped baffle. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a large arc cutting machine for wooden cable reels, which solves the technical problem that band saws are not convenient for cutting the bevel of the connecting end of the fan-shaped baffle in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a large arc cutting machine for wooden cable reels, comprising: A cutting device having a cutting platform and a band saw that penetrates the cutting platform; A sliding frame is slidably mounted on the cutting platform. The sliding trajectory of the sliding frame is arc-shaped, and the band saw is located inside the sliding trajectory of the sliding frame. A support frame is inclinedly mounted on the sliding frame. The support frame can be moved around the band saw by the sliding frame. The support frame is equipped with a positioning mechanism for fixing the fan-shaped baffle on the support frame. The fan-shaped baffle on the support frame can be cut by the band saw as it moves with the support frame.

[0006] For example, in at least one embodiment of the present invention, the large arc cutting machine for wooden cable reels is provided, in which the end of the support frame away from the band saw is swayed on the sliding frame. The large arc cutting machine for wooden cable reels also includes an angle adjustment mechanism for adjusting the tilt angle of the support frame, so that the support frame can change the bevel angle on the fan-shaped baffle by adjusting the tilt angle.

[0007] For example, in at least one embodiment of the large arc cutting machine for wooden cable reels provided by this utility model, the tilt angle adjustment mechanism includes: A sliding block is slidably mounted on the sliding frame and is located below the support frame. The sliding direction of the sliding block is radial along the sliding trajectory of the sliding frame. The connecting rod is hinged at one end to the support frame near the band saw, and the other end is raised and lowered on the sliding block. The connecting rod can push the support frame to swing under the action of the sliding block.

[0008] For example, the large arc cutting machine for wooden cable reels provided in at least one embodiment of this utility model further includes: A lead screw is rotatably mounted on the sliding frame, and the lead screw is threadedly connected to the sliding block. A transmission unit is provided at one end of the lead screw. This transmission unit is used to connect with an external drive mechanism so that the lead screw can rotate under the action of the external drive mechanism.

[0009] For example, in at least one embodiment of the large arc cutting machine for wooden cable reels provided by this utility model, the positioning mechanism includes: There are two stop bars, which are respectively set on both sides of the support frame. The two stop bars are used to support the two sides of the fan-shaped baffle, and the distance between the two stop bars gradually decreases along the direction of the band saw.

[0010] For example, in the large arc cutting machine for wooden cable reels provided in at least one embodiment of the present invention, the support frame has four elongated holes, which are located on both sides of the support frame. The two ends of the stop bar are fixed in the two elongated holes one by one by fasteners so that the stop bar can fit the two sides of the fan-shaped baffles of different sizes.

[0011] For example, the large arc cutting machine for wooden cable reels provided in at least one embodiment of this utility model further includes: The handle is rotatably mounted on the cutting platform at one end and mounted on the sliding frame at the other end. The rotation axis of the handle coincides with the sliding path axis of the sliding frame.

[0012] For example, in the large arc cutting machine for wooden cable reels provided in at least one embodiment of the present invention, the support frame has a number of process holes for weight reduction.

[0013] The beneficial effects of this utility model are as follows: In this invention, by setting a sliding frame and an inclined support frame, the fan-shaped baffle can move in an arc around the band saw, thereby realizing the cutting of the bevel shape of the connecting end of the fan-shaped baffle by the band saw. This overcomes the limitation of the band saw in the prior art that it can only cut simple planar shapes, and meets the needs of fan-shaped baffle bevel cutting in the production of wooden cable reels.

[0014] The arc-shaped sliding trajectory of the sliding frame and the positioning mechanism ensure that the position of the fan-shaped baffle is fixed during the cutting process, so that the bevel size and shape of the arc-shaped baffles of different sizes are consistent. This helps to improve the quality of the connection between the fan-shaped baffle and the cylinder, and further enhances the overall structural stability of the wooden cable reel.

[0015] The cutting machine's structural design makes operation relatively simple. Workers only need to fix the fan-shaped baffle on the support frame and start the equipment to complete the cutting, reducing the complexity and difficulty of manual operation and improving production efficiency.

[0024] like Figures 1-5The diagram illustrates a large circular arc cutting machine for wooden cable reels according to an embodiment of the present invention. It includes a cutting device 100 with a cutting platform 110 and a band saw 120, a sliding frame 200, and a support frame 300. The cutting platform 110 is a square or circular plane with sufficient strength and stability to withstand various forces during the cutting process. A through groove is cut into the cutting platform 110, the width of which is slightly larger than the thickness of the band saw 120, allowing the band saw 120 to move freely within the groove while ensuring a small gap between the band saw 120 and the platform to prevent the wood from wobbling during cutting. The band saw 120 is driven by a motor installed below the cutting platform 110, which drives the band saw 120 via a belt or chain transmission. The tension of the band saw 120 can be adjusted by an adjustment device to ensure the saw blade maintains appropriate tension during cutting, preventing blade breakage or uneven cutting.

[0025] The sliding frame 200 adopts a metal frame structure. Multiple rollers or sliders are installed at the bottom of the sliding frame 200. These rollers or sliders cooperate with the rails on the surface of the cutting platform 110 to achieve an arc-shaped sliding motion of the sliding frame 200 on the cutting platform 110. The rails can be grooves machined into the surface of the cutting platform 110 or guide rails installed on the platform surface. The sliding frame 200 can be driven manually, electrically, hydraulically, or pneumatically. The band saw 120 is located inside the arc-shaped sliding rail of the sliding frame 200.

[0026] The support frame 300 is installed at an angle on the sliding frame 200 by welding or bolting, with the height of the end of the support frame 300 closest to the band saw 120 and the height of the end furthest from the band saw 120 varying. The tilt angle of the support frame 300 is adjusted according to the required angle of the fan-shaped baffle bevel, generally between 30° and 60°. The support frame 300 is used to support the arc-shaped baffle to be cut. A positioning mechanism 400 for fixing the arc-shaped baffle is also provided on the support frame 300. The positioning mechanism 400 can, on the one hand, keep different arc-shaped baffles in the same position on the support frame 300, thereby ensuring the consistency of cutting each arc-shaped baffle, and on the other hand, ensure the stability of the arc-shaped baffle during cutting.

[0027] Working principle: First, the sector-shaped baffle to be cut is placed on the support frame 300, and the positioning mechanism 400 fixes the sector-shaped baffle on the support frame 300 to ensure accurate positioning. The band saw 120 is started, and the motor drives the band saw 120 to rotate. Then, the control system starts the drive device of the sliding frame 200, causing the sliding frame 200 to slide along the arc-shaped track on the cutting platform 110. Because the support frame 300 is installed at an angle on the sliding frame 200, and the band saw 120 is located inside the sliding track of the sliding frame 200, when the sliding frame 200 moves, the support frame 300 will move around the band saw 120, causing the sector-shaped baffle on the support frame 300 to gradually approach the band saw 120 during the movement and be cut by the band saw 120.

[0028] By setting up a sliding frame 200 and an inclined support frame 300, the fan-shaped baffle can move in an arc around the band saw 120, thereby realizing the cutting of the bevel shape of the connecting end of the fan-shaped baffle by the band saw 120. This overcomes the limitation of the band saw 120 in the prior art that can only cut simple planar shapes, and meets the needs of fan-shaped baffle bevel cutting in the production of wooden cable reels.

[0029] The arc-shaped sliding trajectory of the sliding frame 200 and the positioning mechanism 400 ensure that the position of the fan-shaped baffle is fixed during the cutting process, so that the bevel size and shape of the arc-shaped baffles of different sizes are consistent. This is beneficial to improving the quality of the connection between the fan-shaped baffle and the cylinder, and further enhancing the overall structural stability of the wooden cable reel.

[0030] The structural design of this cutting machine makes operation relatively simple. Workers only need to fix the fan-shaped baffle on the support frame 300 and start the equipment to complete the cutting, which reduces the complexity and difficulty of manual operation and improves production efficiency.

[0031] Furthermore, the end of the support frame 300 furthest from the band saw 120 is swayed on the sliding frame 200. Optionally, a hinge seat is provided on the sliding frame 200, with a pin hole. A matching hinge block is installed at the end of the support frame 300 furthest from the band saw 120. Its shape matches the hinge seat, and it has a pin hole aligned with the pin hole of the hinge seat. By inserting a pin into the two aligned pin holes, the support frame 300 is swayed on the sliding frame 200, allowing the support frame 300 to sway around the pin and change its tilt angle.

[0032] The large arc cutting machine for wooden cable reels also includes an angle adjustment mechanism 500 for adjusting the tilt angle of the support frame 300. The tilt angle of the support frame 300 can be adjusted by the angle adjustment mechanism 500, thereby changing the bevel angle on the fan-shaped baffle as needed.

[0033] Furthermore, the tilt adjustment mechanism 500 includes a sliding block 510 and a connecting rod 520. Optionally, a groove is formed radially on the sliding frame 200 along its sliding trajectory. The shape and size of the groove match the sliding block 510. A slider that mates with the groove is provided on the sliding block 510. The slider can be a protrusion integrally formed on the sliding block 510, or it can be an independent component fixed to the bottom of the sliding block 510 by bolts. Through the cooperation of the slider and the groove, the sliding block 510 can slide smoothly radially on the sliding frame 200.

[0034] One end of the connecting rod 520 is hinged to the end of the support frame 300 near the band saw 120 via a pin. The pin passes through corresponding hinge holes on the connecting rod 520 and the support frame 300 and is secured with a nut or a locking pin, allowing the connecting rod 520 to rotate freely relative to the support frame 300. A dovetail groove adapted to the connecting rod 520 is provided on the sliding block 510, extending along the vertical direction of the sliding block 510.

[0035] When the sliding block 510 slides toward the band saw 120, the sliding block 510 pushes the support frame 300 to swing upward around the swing axis through the connecting rod 520. At this time, one end of the connecting rod 520 rotates relative to the hinge end of the support frame 300, and the other end of the connecting rod 520 rises along the dovetail groove on the sliding block 510.

[0036] Furthermore, it also includes a lead screw 610 and a transmission unit 620. The lead screw 610 is a ball screw, which is mounted on the sliding frame 200 via bearings. The bearing housing is fixed to the sliding frame 200 to ensure smooth rotation of the lead screw 610. The lead screw 610 and the sliding block 510 are connected by a threaded connection. The internal thread of the sliding block 510 precisely matches the external thread of the lead screw 610, ensuring that the sliding block 510 can move smoothly along the axial direction of the lead screw 610 when the lead screw 610 rotates.

[0037] The transmission unit 620 is fixed to one end of the lead screw 610 by welding or threaded connection. Depending on the type of transmission, the transmission unit 620 can be of various types. For example, in a manually driven manner, the transmission unit 620 is in the form of a hand-cranked wheel. If a motor-driven manner is used, the transmission unit 620 can be connected to the drive end of the motor via a keyway. In short, the transmission unit 620 can transmit power from an external drive source to the lead screw 610, thereby causing the lead screw 610 to rotate.

[0038] Furthermore, the positioning mechanism 400 includes two stop bars 410, which are fixed to both sides of the support frame 300 by bolts. If bolt fixing is used, threaded holes adapted to the stop bars 410 are pre-machined on both sides of the support frame 300, and corresponding through holes are opened on the stop bars 410. Bolts are passed through the through holes and tightened into the threaded holes to securely install the stop bars 410 onto the support frame 300. This installation method facilitates disassembly when the stop bars 410 need to be replaced or their position adjusted. The distance between the two stop bars 410 gradually decreases along the band saw 120 direction, so that after the stop bars 410 abut against the sides of the fan-shaped baffle, they can prevent the fan-shaped baffle from falling down the inclined surface of the support frame 300, ensuring the fixed position of the fan-shaped baffle.

[0039] Furthermore, to adapt the positioning mechanism 400 to different models of arc-shaped baffles, the support frame 300 has four elongated holes 310, with every two elongated holes 310 used to fix a stop bar 410. The stop bar 410 has one round hole and one elongated hole 310, allowing it to be fixed to the support frame 300 using bolts and nuts. Depending on the size of the different sector-shaped baffles, not only can the distance between the two stop bars 410 be adjusted, but the tilt angle of the stop bar 410 can also be adjusted using the round hole on the stop bar 410 as the center.

[0040] Furthermore, a bearing seat is installed on the cutting platform 110. The bearing seat is fixed to the surface of the cutting platform 110 and can be fixed by bolt connection or welding to ensure its stability. The axis of the bearing seat coincides with the axis of the sliding path of the sliding frame 200. One end of the handle 700 is machined with a journal that matches the inner diameter of the bearing. The journal is inserted into the inner hole of the bearing to achieve a rotatable connection of one end of the handle 700 on the cutting platform 110. A connecting seat is provided at the other end of the handle 700. The connecting seat is fixed to the handle 700 by welding or bolt connection. A connection point is provided at a corresponding position on the sliding frame 200. The connection point between the connecting seat and the sliding frame 200 is connected by a pin or bolt to ensure a firm connection between the handle 700 and the sliding frame 200. The handle provides the operator with a convenient grip and force application point, enabling the operator to push the sliding frame 200 along the arc track more easily and accurately. Compared with directly pushing the sliding frame 200, the operation is more flexible and comfortable, reducing the operator's labor intensity and improving work efficiency.

[0041] Furthermore, the support frame 300 has several process holes 320 for weight reduction. The process holes 320 are usually designed to be circular, square or elliptical, and the specific shape can be selected according to the structure and manufacturing process of the support frame 300.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
