Description

A band saw blade winding device Technical Field

[0001] This utility model relates to the field of winding device technology, specifically to a band saw blade winding device. Background Technology

[0002] A band saw blade is a strip-shaped tool with a continuous toothed edge used for cutting wood, metal, and other materials. Its production process involves several key steps to ensure the high performance and durability of the final product. The production of band saw blades generally involves the following processes: raw material preparation, tooth shaping, heat treatment, surface treatment, inspection, and packaging. After production, the band saw blade needs to be wound up for easy transfer.

[0003] Chinese Patent No. CN212449838U discloses a novel bimetal band saw blade winding device. By placing multiple winding discs on a support shaft and using movable support components to limit their movement, multiple bimetal band saws can be wound simultaneously, improving winding efficiency. Furthermore, by setting extrusion components on the winding discs, along with end placement boxes and limiting and fixing components, the tail end of the bimetal band saw can be limited and fixed. The operation is simple and convenient, and the position of the limiting and fixing components can be adjusted according to the winding diameter of the bimetal band saw to fix its tail end, making it even more convenient to use.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: in order to achieve the tail limit when the band saw blade is wound up, the conventional winding reel structure needs to be modified, which means that the conventional general-purpose winding reel cannot achieve this function. Summary of the Invention

[0005] The purpose of this invention is to address the problem in the background art that requires structural modifications to conventional winding reels to achieve rapid fixation of the band saw blade winding tail, and to propose a band saw blade winding device.

[0006] The technical solution of this utility model: a band saw blade winding device, comprising:

[0007] The frame has two spindle support plates on it, and the top of the spindle support plates has a placement groove.

[0008] The winding reel includes a main shaft, a central column sleeved on the main shaft, and limiting plates set at both ends of the central column. The main shaft passes through a placement slot, and a power mechanism that drives the main shaft to rotate is provided on the frame.

[0009] The tail end limiting mechanism is located between two limiting discs, allowing the band saw blade to pass through. After winding, it fixes the tail end of the band saw blade and secures itself between the two limiting discs.

[0010] And a support frame is set on the main shaft support plate. A top frame is set on the top of the support frame. A guide rod is vertically slidably set on the top frame. A counterweight is set on the top of the guide rod. The bottom of the guide rod is connected to the tail end limiting mechanism.

[0011] Preferably, the power mechanism includes a motor mounting base that is slidably mounted on the frame along the main shaft axis, a motor mounted on the motor mounting base, a floating joint connecting the motor output shaft and the main shaft, and a telescopic device mounted on the frame to drive the motor mounting base to slide.

[0012] Preferably, an anti-jumping mechanism is provided at the end of the spindle away from the power mechanism. The anti-jumping mechanism includes a flipping pressure plate rotatably disposed on the top of the spindle support plate, and a locking bolt for fixing the flipping pressure plate to the spindle support plate. The flipping pressure plate is located above the spindle and has a gap with the spindle.

[0013] Preferably, a groove is opened on the central column, and a pressure plate is rotatably installed in the groove. Multiple opposing threaded holes are provided on the pressure plate and the groove. The first end of the band saw blade is inserted into the groove, and the pressure plate is fixed by bolts after pressing the band saw blade.

[0014] Preferably, the tail limiting mechanism includes a box through which the band saw blade passes, a main screw threaded through the top of the box, a pressure plate located at the bottom of the main screw and inside the box, a disc located at the top of the main screw, and a limiting plate tilted and rotatably mounted on the outer wall of the top of the box. The disc descends and presses down on the limiting plate so that the end of the limiting plate abuts against the inner wall of the limiting disc. The disc is detachably connected to the bottom of the guide rod.

[0015] Preferably, a support rod is rotatably mounted on the top outer wall of the box, the bottom of the limiting plate is connected to the support rod, the bottom of the limiting plate is located below the disc, and the top is located on the outer side of the circumferential surface above the disc. A spring is mounted on the box, and the top of the spring contacts the limiting plate.

[0016] Preferably, the top of the limiting plate is fitted with an elastic sleeve.

[0017] Preferably, multiple connecting screws are vertically arranged on the top of the disc, a base plate is provided at the bottom of the guide rod, multiple through holes are provided on the base plate for the connecting screws to pass through, a support ring is provided on the connecting screw, the base plate contacts the support ring, and a nut is fitted on the connecting screw.

[0018] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: After winding, remove multiple nuts, pull the guide rod upward, and then rotate the disc to drive the pressure plate downward. The pressure plate presses down on the tail end of the band saw blade. At the same time, the descending disc will drive the limiting plate to flip downward, so that the elastic sleeve is pressed against the inner wall of the limiting plate, completing the fixation of the box itself. At this point, the tail end of the band saw blade is fixed. Then, disconnect the connection between the main shaft and the floating joint. The telescopic device extends to push the floating joint away from the main shaft and opens the flipping pressure plate upward, transferring the winding disc away. No modifications to the winding disc are required. The tail end of the band saw blade can be stably fixed by setting a tail end limiting mechanism, resulting in lower operating costs and a wider range of applications. Attached Figure Description

[0024] Example 1

[0025] As shown in Figures 1 and 2, the band saw blade winding device proposed in this utility model includes:

[0026] A frame 1 is provided with two spindle support plates 2, and a placement groove 3 is provided on the top of the spindle support plates 2.

[0027] The winding reel includes a main shaft 4, a central column 11 sleeved on the main shaft 4, and limiting plates 10 set at both ends of the central column 11. The main shaft 4 passes through the placement groove 3. A power mechanism that drives the main shaft 4 to rotate is set on the frame 1. The winding reel is a common winding structure and is not modified. A groove is opened on the central column 11, and a pressure plate 12 is rotatably set in the groove. Multiple opposing threaded holes 13 are set on the pressure plate 12 and the groove. The first end of the band saw blade winding is inserted into the groove. After the pressure plate 12 presses down on the band saw blade, the pressure plate 12 is fixed by bolts.

[0028] The tail end limiting mechanism is located between the two limiting discs 10, allowing the band saw blade to pass through. After winding, it fixes the tail end of the band saw blade and secures itself between the two limiting discs 10.

[0029] And a support frame 16, which is set on the main shaft support plate 2. A top frame 17 is set on the top of the support frame 16. A guide rod 19 is vertically slidably set on the top frame 17. A counterweight 18 is set on the top of the guide rod 19. The bottom of the guide rod 19 is connected to the tail end limiting mechanism.

[0030] During the winding process, the tail-end limiting mechanism, under the action of the counterweight 18, can always press on the wound band saw blade and continuously move upward as the winding process progresses. After winding is completed, the tail end of the band saw blade is fixed by the tail-end limiting mechanism. Then, the connection between the guide rod 19 and the tail-end limiting mechanism is disconnected, and the winding reel can be removed. The tail-end limiting mechanism is used as a set of limiting accessories as a whole, without requiring any modification to the winding reel. A conventional winding reel can quickly complete the fixing of the tail end of the band saw blade, resulting in lower operating costs.

[0031] Example 2

[0032] As shown in Figures 1 and 2, this utility model proposes a band saw blade winding device. Compared with Embodiment 1, this embodiment details the structure of the power mechanism and the anti-jumping mechanism.

[0033] The power mechanism includes a motor mounting base 7 that is slidably mounted on the frame 1 along the main shaft 4, a motor 6 mounted on the motor mounting base 7, a floating joint 5 that connects the output shaft of the motor 6 and the main shaft 4, and a telescopic device 8 mounted on the frame 1 that drives the motor mounting base 7 to slide.

[0034] In an optional embodiment, a slide groove 9 is provided on the frame 1, and a slider is provided at the bottom of the motor mounting base 7. The slider is inserted into the slide groove 9 and slides in cooperation. The telescopic device 8 is a cylinder or a hydraulic cylinder. After the connection between the floating joint 5 and the main shaft 4 is released, the telescopic device 8 extends to push the motor mounting base 7, the motor 6 and the floating joint 5 away from the main shaft 4. At this time, the take-up reel can be removed. When removing the take-up reel, first push the take-up reel upward and then pull it out horizontally.

[0035] An anti-jump mechanism is provided at the end of the spindle 4 away from the power mechanism. The anti-jump mechanism includes a flipping pressure plate 14 rotatably mounted on the top of the spindle support plate 2, and a locking bolt 15 that fixes the flipping pressure plate 14 to the spindle support plate 2. The flipping pressure plate 14 is located above the spindle 4 and has a gap of less than three millimeters between it and the spindle 4. By pressing the flipping pressure plate 14 on the spindle 4, the stability of the spindle 4 during rotation is improved, and the spindle 4 is also prevented from accidentally jumping out of the placement slot 3, thus improving safety.

[0036] Example 3

[0037] As shown in Figures 3 and 4, this utility model proposes a band saw blade winding device. Compared with Embodiment 1, this embodiment details the structure of the tail limiting mechanism.

[0038] The tail limiting mechanism includes a housing 20 through which the band saw blade passes, a main screw 22 threaded through the top of the housing 20, a pressure plate 21 located at the bottom of the main screw 22 and inside the housing 20, a disc 23 located at the top of the main screw 22, and a limiting plate 27 tilted and rotatably mounted on the outer wall of the top of the housing 20. The disc 23 descends and presses down on the limiting plate 27 so that the end of the limiting plate 27 abuts against the inner wall of the limiting disc 10. The disc 23 is detachably connected to the bottom of the guide rod 19. Specifically, the disc 23... Multiple connecting screws 24 are vertically arranged at the top, and a base plate 25 is provided at the bottom of the guide rod 19. Multiple through holes are provided on the base plate 25 for the connecting screws 24 to pass through. A support ring is provided on the connecting screw 24, and the base plate 25 contacts the support ring. A nut 26 is fitted on the connecting screw 24. During the winding process, the band saw blade is located between the pressure plate 21 and the bottom inner wall of the box body 20. According to actual needs, the distance between the pressure plate 21 and the bottom inner wall of the box body 20 can be adjusted by rotating the disc 23 before connecting the guide rod 19.

[0039] A support rod is rotatably mounted on the top outer wall of the box body 20. The bottom of the limiting plate 27 is connected to the support rod. The bottom of the limiting plate 27 is located below the disc 23, and the top is located on the outer side of the circumferential surface above the disc 23. A spring 29 is installed on the box body 20, and the top of the spring 29 contacts the limiting plate 27. Due to the pushing force of the spring 29, the top of the limiting plate 27 does not contact the limiting disc 10 during the winding process, allowing for normal winding. An elastic sleeve 28 is fitted on the top of the limiting plate 27. The elastic sleeve 28 can be made of elastic rubber or other elastic materials, which can be selected according to the needs.

[0040] In summary, when using this utility model, first place the winding reel in place, then connect the main shaft 4 and the floating joint 5, then pass the first end of the band saw blade through the box 20 and fix it to the central column 11 with the pressure plate 12, then start the motor 6 to start the winding operation. As the winding proceeds, the box 20 rises continuously. After the winding is completed, remove the multiple nuts 26, pull the guide rod 19 upward until it does not affect the operation, then rotate the disc 23 to drive the pressure plate 21 to descend. The pressure plate 21 presses down the tail end of the band saw blade. At the same time, the descending disc 23 will drive the limiting plate 27 to flip downward, so that the elastic sleeve 28 is pressed against the inner wall of the limiting plate 10, thus completing the fixation of the box 20 itself. At this point, the tail end of the band saw blade has been fixed. Next, disconnect the main shaft 4 and the floating joint 5. The telescopic device 8 extends to push the floating joint 5 away from the main shaft 4 and opens the flip-over pressure plate 14 upward. Then, push the guide rod 19 upward to the top. One person holds it while another person uses a forklift to fork away the winding reel, or the winding reel can be lifted away using a lifting device. This utility model does not require any modification to the winding reel. By setting a tail-end limiting mechanism, the tail end of the band saw blade can be stably fixed, resulting in lower operating costs and a wider range of applications.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
