Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fishing rod production, and particularly relates to a fishing rod section straightening machine. BACKGROUND

[0002] Traditional fishing rods rely on carbon fiber and other materials, which have the problems of high production energy consumption, high cost and non-renewable. Recycled plastic can reduce the dependence on non-renewable resources, and can also control the cost of raw materials. After modification and processing, it can be used for fishing rod manufacturing, which can realize resource recycling and reduce environmental load. However, when the recycled material is extruded or wound into a shape, it is easy to have uneven internal stress and deformation, which causes the rod body to bend, and the fishing rod straightening process is needed to mechanically correct it to ensure the straightness and mechanical properties of the rod body.

[0003] Small production enterprises often use simple straightening tables, and manually judge the bending by observation and hand feeling, and adjust the pressure by padding or manual adjustment, which is low in efficiency in batch production. The existing patent (publication number CN222792749U) fishing rod straightening device uses an electric motor to drive the fishing rod to move, and cooperates with the straightening assembly to realize automatic straightening, which improves the efficiency, but still has the following problems: first, the horizontal and vertical straightening assemblies are cross-positioned, and the bending direction needs to be observed manually before the fishing rod is fixed to ensure that the bending surface corresponds to the straightening assembly, which is complicated to operate; second, when the bending surface is opposite to the horizontal straightening assembly, the two side return springs are unevenly stressed, and it is difficult to achieve standard straightening effect. SUMMARY

[0004] In view of the problems in the prior art that the bending direction of the fishing rod needs to be judged manually, resulting in low straightening efficiency and poor straightening effect, a fishing rod section straightening machine is provided.

[0005] The purpose is that after the fishing rod is clamped and positioned, a plurality of straightening wheels are close to the fishing rod, one of the straightening wheels drives the fishing rod to rotate axially, and the plurality of straightening wheels cooperate to straighten the rotating fishing rod in all directions, thereby improving the straightening effect and efficiency.

A gear ring is rotatably connected to the side wall of the placement tray near the motor. The gear ring is connected to the coupling shaft. A lever and an arc-shaped rack are provided on the support frame near the motor. The lever is used to drive the gear ring to rotate, and the arc-shaped rack is used to drive the corresponding rotating shaft.

[0007] Furthermore, the placement groove is funnel-shaped, and the sealed end of the placement groove coincides with the center of the placement tray.

[0008] Furthermore, both ends of the connecting shaft are provided with helical grooves, a drive rod is fixedly connected to the sliding sleeve, one end of the drive rod is located in the helical groove, and a hinge rod is hinged together between the clamping member and the sliding sleeve.

[0009] Furthermore, the clamping member includes a slider, which is slidably connected to the side wall of the placement tray. A clamping block is slidably connected to the side of the slider facing the center of the placement tray, and multiple elastic elements are connected together between the clamping block and the slider.

[0010] Furthermore, the gear ring is meshed with multiple driven gears, the driven gears are fixedly connected to their corresponding couplings, a positioning rod is fixedly connected to the gear ring, and the actuating rod is in sliding contact with the corresponding positioning rod.

[0011] Furthermore, a fixed base is fixedly connected to the side of the placement tray facing the positioning rod, and a locking block is slidably connected inside the fixed base. An elastic element two is connected between the locking block and the fixed base. Guide slopes are symmetrically opened on both sides of the locking block, and a positioning groove adapted to the positioning rod is opened in the middle of the locking block. A top block is also fixedly connected to the support frame connected to the actuating lever, and a top rod is fixedly connected to the side of the locking block facing the top block.

[0012] Furthermore, a plurality of drive gears are arranged in a ring at equal intervals on one side of the arc-shaped rack, and the drive gears are connected and fixed to the corresponding rotating shafts.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The placement plate rotates with the cross, allowing the clamping device to automatically clamp and position the end of the fishing rod.

No manual assistance is required for unloading. It is suitable for mass production scenarios and solves the problem of low efficiency in traditional manual operation.

[0017] 3. The centering guide plate in the placement slot automatically guides the fishing rod to remain centered between the two placement trays by adjusting the inclined plane, leaving sufficient space for axial deformation and avoiding uneven straightening caused by positional deviation. At the same time, after the fishing rod is straightened, the centering guide plate automatically retracts into the placement tray, removing the restriction on the fishing rod and allowing the fishing rod to slide automatically away from the placement slot.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Example 1, referring to Figures 1-7 The first embodiment of the present invention provides a fishing rod section straightening machine, including a base plate 1 and two support frames 2 connected thereto. A motor 3 is mounted on the top surface of the base plate 1. A drive shaft 4 is rotatably connected between the two support frames 2. One end of the drive shaft 4 is connected to the motor 3 for transmission. Crosses 5 are fixedly connected to the outer walls of both ends of the drive shaft 4. Placement trays 6 are fixedly connected to the ends of the crosses 5. Placement trays 6 have placement slots 7 for placing fishing rods. Multiple rotating shafts 8 and connecting shafts 11 are arranged in a ring at equal intervals between the two horizontally arranged placement trays 6. The two ends of the rotating shafts 8 are connected to each other. Each component is rotatably connected to a clamping member 9, which is slidably connected to the placement plate 6. Multiple straightening wheels 10 are fixedly connected to the rotating shaft 8 at equal intervals. Both ends of the connecting shaft 11 are movably sleeved with sliding sleeves 14, which are movably connected to the corresponding clamping member 9. A toothed ring 16 is rotatably connected to the side wall of the placement plate 6 near the motor 3. The toothed ring 16 is connected to the connecting shaft 11 for transmission. A toggle rod 17 and an arc-shaped rack 25 are provided on the support frame 2 near the motor 3. The toggle rod 17 is used to drive the toothed ring 16 to rotate, and the arc-shaped rack 25 is used to drive the corresponding rotating shaft 8.

[0022] Specifically, motor 3 drives drive shaft 4 to rotate, causing cross 5 and placement plate 6 to rotate. The fishing rod section is placed in the placement slot 7 of the two horizontally arranged placement plates 6. When the actuating rod 17 contacts the toothed ring 16 that rotates with the placement plate 6, it causes the toothed ring 16 to rotate. The connecting shaft 11 causes the two sliding sleeves 14 connected to it to move away from each other. The sliding sleeves 14 cause the clamping member 9 to slide towards the center of the placement plate 6. Multiple clamping members 9 move synchronously to clamp and position the end of the fishing rod section. The rotating shaft 8 connected to the clamping member 9 drives the straightening wheel 10 to fit against the outer wall of the fishing rod section. Then, the arc-shaped rack 25 drives the rotating shaft 8 and the straightening wheel 10 to rotate. Multiple sets of straightening wheels 10 work together to drive the fishing rod section to rotate around its own axis. At the same time, the straightening wheels 10 arranged in a ring at equal intervals squeeze and straighten the bent part of the fishing rod.

[0023] The multiple straightening wheels 10 on the rotating shaft 8 can provide multi-point support and straightening along the length of the fishing rod section, avoiding excessive local stress that could damage the fishing rod section and ensuring uniform straightening effect across all sections. The rolling compression achieves efficient straightening of the fishing rod section, improving both straightening quality and efficiency. Simultaneously, rolling friction between the straightening wheels 10 and the fishing rod section reduces wear on the surface of the fishing rod section.

[0024] Among them, reference Figure 1 , Figure 2 The drive shaft 4 and the support frame 2 are connected by a common bearing to ensure the smooth rotation of the drive shaft 4. The end of the drive shaft 4 near the motor 3 passes through the support frame 2 and is connected to the output shaft of the motor 3 by chain drive. One of the support frames 2 is also equipped with a control panel, which is used to control the start and stop of the motor 3 and its speed.

[0025] Reference Figure 3 The placement groove 7 is funnel-shaped, and the sealed end of the placement groove 7 coincides with the center of the placement plate 6.

[0026] Specifically, the flared design makes it easier to put the fishing rod section into the placement slot 7, and the sealed end coincides with the center of the placement plate 6 to ensure that the fishing rod section is in the center position. This ensures that the fishing rod is aligned with the axis of the placement plate 6 after the multiple clamping parts 9 work together to clamp the fishing rod.

[0027] Reference Figure 5 , Figure 6 Both ends of the connecting shaft 11 are provided with spiral grooves 12. A drive rod 13 is fixedly connected to the sliding sleeve 14. One end of the drive rod 13 is located in the spiral groove 12. The clamping member 9 and the sliding sleeve 14 are hinged together by a hinge rod 15.

[0028] Specifically, when the connecting shaft 11 rotates, the spiral groove 12 drives the sliding sleeve 14 to move axially through the drive rod 13, and then pushes the clamping member 9 to slide through the hinge rod 15. Multiple clamping members 9 move closer to each other to achieve stable clamping of the fishing rod end.

[0029] The spiral groove 12 and the drive rod 13 work together to achieve efficient transmission, enabling the clamping member 9 to quickly clamp or release the fishing rod.

[0030] Reference Figure 6 The clamping component 9 includes a slider 91, which is slidably connected to the side wall of the placement plate 6. A clamping block 92 is slidably connected to the side of the slider 91 facing the center of the placement plate 6. Multiple elastic elements are connected between the clamping block 92 and the slider 91.

[0031] Specifically, the sliding sleeve 14 drives the slider 91 to slide horizontally along the radially opened limiting groove on the placement plate 6. All the sliders 91 on the placement plate 6 move synchronously, realizing the clamping and fixing of the fishing rod end by multiple clamping blocks 92. The clamping blocks 92 can translate within a certain range along the axial direction of the placement plate 6 on the slider 91. With this design, when the fishing rod has a large degree of curvature, the extension deformation during straightening can be realized through the sliding cooperation between the clamping blocks 92 and the sliders 91.

[0032] The clamping block 92 is made of flexible rubber on the side facing the center of the placement plate 6, and has a concave groove adapted to the fishing rod to ensure a more stable clamping of the fishing rod.

[0033] Understandably, the diameters of the straightening wheels 10 on the same rotating shaft 8 increase sequentially from left to right (or from right to left) to suit the frustum-shaped fishing rod structure, ensuring that multiple straightening wheels 10 are in effective contact with the fishing rod and guaranteeing the straightening effect.

[0034] Reference Figure 5 , Figure 7 Multiple driven gears 18 are meshed on the gear ring 16. The driven gears 18 are connected and fixed to the corresponding connecting shafts 11. A positioning rod 19 is fixedly connected to the gear ring 16. The actuating rod 17 slides in contact with the corresponding positioning rod 19.

[0035] Specifically, as the placement plate 6 rotates with the cross 5, the positioning rod 19 gradually contacts the actuating rod 17, and the actuating rod 17 cannot move. At this time, the positioning rod 19 is blocked by the actuating rod 17, which drives the gear ring 16 to rotate. The gear ring 16 cooperates with the driven gear 18 to drive the connecting shaft 11 to rotate. When the positioning rod 19 tilts to the end and no longer contacts the actuating rod 17, the connecting shaft 11 stops rotating. At this time, the clamping member 9 completes the clamping and fixing of the fishing rod.

[0036] Reference Figures 7-9A fixed base 20 is fixedly connected to the side of the placement plate 6 facing the positioning rod 19. A locking block 21 is slidably connected inside the fixed base 20. An elastic element 2 is connected between the locking block 21 and the fixed base 20. Guide slopes are symmetrically opened on both sides of the locking block 21. A positioning groove 22 that matches the positioning rod 19 is opened in the middle of the locking block 21. A top block 23 is also fixedly connected to the support frame 2 connected to the toggle rod 17. A top rod 24 is fixedly connected to the side of the locking block 21 facing the top block 23.

[0037] Specifically, when the positioning rod 19 rotates, it slides along the guide slope of the locking block 21 and compresses the elastic element 2. After rotating to the correct position, the locking block 21 resets under the action of the elastic element 2, and the positioning groove 22 locks the positioning rod 19, thereby restricting the rotation of the toothed ring 16, and thus ensuring stable contact between the clamping member 9, the straightening wheel 10, and the fishing rod. As the placement plate 6 rotates a certain angle, the top rod 24 contacts the top block 23 and moves along the slope of the top block 23, again driving the locking block 21 to compress the elastic element 2. When the positioning rod 19 disengages from the locking block 21, the elastic element 2 drives the locking block 21 to reset.

[0038] Among them, reference Figure 3 The slider 91 and the placement plate 6 are connected by an elastic element 3. When the clamping member 9 moves to contact the fishing rod, the elastic element 3 stretches and stores force. When the top rod 24 contacts the top block 23 and the locking block 21 is disengaged from the positioning rod 19, the elastic element 3 resets, causing the connecting shaft 11 to flip and drive the toothed ring 16 to reset.

[0039] Reference Figure 3 , Figure 4 The arc-shaped rack 25 has multiple drive gears 26 arranged in a ring at equal intervals on one side, and the drive gears 26 are connected and fixed to the corresponding rotating shafts 8.

[0040] Specifically, when the placement plate 6 rotates, it drives the drive gear 26 to roll along the arc-shaped rack 25, causing the rotating shaft 8 and the straightening wheel 10 to rotate. The actively rotating straightening wheel 10 drives the fishing rod to rotate, and multiple sets of straightening wheels 10 work together to achieve all-round straightening of the fishing rod. The rotation of the placement plate 6 itself provides power to the straightening wheel 10, eliminating the need for an additional drive device and saving energy.

[0041] It should be noted that elastic element one, elastic element two, and elastic element three all adopt elastic structures that can automatically extend, retract, and reset. In this technical solution, springs are preferred.

[0042] Example 2, refer to Figure 7 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: one end of the lever 17 is fixedly connected to an adjusting block 27, the adjusting block 27 is slidably connected to the corresponding support frame 2, and a bolt is threaded on the adjusting block 27, with one end of the bolt abutting against the side wall of the support frame 2.

[0043] Specifically, the adjusting block 27 has an I-shaped structure and slides in conjunction with the vertically opened through hole on the support frame 2. After the adjusting block 27 is adjusted up and down, its movement can be limited by rotating the bolt. When the adjusting block 27 drives the actuating rod 17 to move up and down, it can change the contact time with the positioning rod 19, thereby changing the rotation angle of the toothed ring 16, and thus changing the size of the clamping cavity formed by the cooperation of multiple clamping parts 9, so that it can be used for fishing rods of different sizes. The rest of the structure is the same as that of Embodiment 1.

[0044] Example 3, referring to Figure 10 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that a central guide plate 28 is provided in the placement groove 7. One end of the central guide plate 28 is slidably connected to the sliding groove opened on the placement plate 6, and an adjustment slope 29 is provided on the central guide plate 28.

[0045] Specifically, when the opening of the placement slot 7 is tilted upwards, the centering guide plate 28 moves downwards into the placement slot 7 under the action of gravity. After the fishing rod is placed in, it rolls downwards along the slot, and its end contacts the adjusting inclined surface 29. This automatically guides the fishing rod to maintain a centered position between the two placement plates 6, reserving sufficient space for the axial deformation of the fishing rod during the straightening process and avoiding problems such as excessive local stress or uneven straightening caused by positional deviation. in, Figure 10 After the placement tray 6 is rotated 180° clockwise, the opening of the placement groove 7 tilts downwards. At this time, the central guide plate 28 retracts into the chute under the action of gravity, eliminating the obstruction in the placement groove 7. This allows the straightened fishing rod to slide automatically away from the placement groove 7 under its own weight, without the need for manual assistance in unloading, thus improving the automation level and work efficiency of the equipment. The rest of the structure is the same as that in Embodiment 2.

[0046] Based on embodiments 1-3, the working principle of this invention is as follows: Motor 3 is started, and motor 3 drives drive shaft 4 to rotate clockwise. Figure 1 (In this state). Place the fishing rod section at the nine o'clock position ( Figure 1 In the two placement trays 6 (with openings tilted upwards), the centering guide plate 28 automatically guides the fishing rod to the center. When the placement trays 6 rotate with the cross 5, the positioning rod 19 contacts the actuating rod 17, causing the gear ring 16 to rotate. This, in turn, causes the connecting shaft 11 to rotate via the driven gear 18. The spiral groove 12 cooperates with the drive rod 13 to move the sliding sleeve 14, which, via the hinge rod 15, pushes the clamping member 9 to slide towards the center. The clamping block 92 clamps and fixes the end of the fishing rod. At the same time, the clamping member 9 drives the straightening wheel 10 to contact the fishing rod via the rotating shaft 8. When the drive gear 26 rolls along the arc-shaped rack 25, the rotating shaft 8 drives the straightening wheel 10 to rotate. Multiple straightening wheels 10 squeeze and straighten the fishing rod from all directions. After straightening, when the placement tray 7 rotates to the point where the opening faces downwards, the fishing rod is automatically unloaded.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention 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 solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
