Description

Technical Field

[0001] This utility model relates to the field of hollow board production, and in particular to a durable cutting device for a hollow board production line. Background Technology

[0002] Hollow core boards are widely used in packaging, logistics, and construction due to their advantages such as being lightweight, impact-resistant, and environmentally friendly. The efficiency and precision of the board cutting process on the production line directly affect the product quality.

[0003] The current cutting equipment suffers from the core problem of rapid blade wear and frequent replacement, severely hindering the stable and efficient operation of the production line. Because hollow core panels often contain reinforcing fillers such as glass fiber and calcium carbonate, the fillers continuously scrape the blade during direct cutting, causing chipping and curling of the cutting edge. Furthermore, the hollow structure leads to uneven stress and concentrated pressure on the blade, requiring some blades to be completely replaced due to localized wear. Since blades are often fixed with multiple sets of bolts, each replacement requires significant downtime, and repeated daily shutdowns directly impact the actual working efficiency of the production line. In addition, repeated disassembly can deform the blade mounting groove, causing positioning errors and cutting defects. Failure to replace worn blades in a timely manner can also lead to safety accidents such as hollow core panel cracking and blade breakage.

[0004] To address the issues of rapid wear and frequent replacement of cutters in hollow board production lines.

[0005] Therefore, it is necessary to provide a new durable cutting device for hollow board production lines to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a durable cutting device for a hollow board production line.

[0007] This utility model provides a durable cutting device for a hollow board production line, comprising: a frame beam, with frame ears fixedly connected to both ends of the frame beam; a main shaft disposed in the frame beam, with both ends of the main shaft rotatably connected to two frame ears respectively; a multi-grooved shaft cylinder fixedly connected to the main shaft, with multiple mounting grooves on the multi-grooved shaft cylinder, and cutters installed in each of the multiple mounting grooves; and an automatic adjustment mechanism, comprising a side frame fixedly connected to one end of the frame beam; a gear ring fixedly connected to one end of the main shaft; a rack disposed on the rear side of the gear ring; the rack meshing with the gear ring; and a control component disposed between the rack and the side frame.

[0008] Preferably, the plurality of mounting slots are arranged in an equidistant ring.

[0009] Preferably, the control component includes a drive block, which is fixedly connected to a rack. Two vertical rods are symmetrically fixedly connected in the side frame, and the drive block is slidably connected to the two vertical rods. An electric cylinder is installed at the upper end of the side frame, and the output end of the electric cylinder is fixedly connected to the drive block.

[0010] Preferably, both ends of the main shaft are fixedly connected to side locking discs, and each of the two side locking discs is provided with multiple locking holes, which are arranged in an equidistant ring.

[0011] Preferably, both sides of the two side locking discs are provided with locking plates, and each of the two locking plates is fixedly connected with a locking pin.

[0012] Preferably, a crossbeam is fixedly connected to the rear side of the frame beam, and a crossbar is fixedly connected between the crossbeams. The two locking plates are slidably connected to the two ends of the crossbar respectively.

[0013] Preferably, a drive shaft is rotatably connected between the crossbeams, a motor is installed and connected to one end of the crossbeam, the output end of the motor is fixedly connected to the drive shaft, the two ends of the drive shaft are provided with threads in opposite directions, both locking plates are provided with threaded openings, and the two locking plates are respectively threaded to the two ends of the drive shaft.

[0014] Compared with related technologies, the durable cutting device for a hollow board production line provided by this utility model has the following advantages:

[0015] 1. This utility model uses the output end of an electric cylinder to push a drive block to slide stably along two vertical rods. The rack moves synchronously with the drive block, thereby driving the gear ring meshing with it to rotate. The gear ring drives the multi-groove cylinder on the main shaft to rotate synchronously, thereby driving the cutters in multiple mounting slots to rotate and alternately adjust the working angle. This allows for quick cutter replacement without repeated machine stops for disassembly, reducing the working time required for multiple machine stops for loading and unloading due to cutter wear, extending the overall service life of the equipment, and avoiding production line interruptions caused by frequent machine stops.

[0016] 2. This utility model uses a motor to drive the drive shaft to rotate, and uses threaded transmission to drive the locking plate to quickly approach the side locking plate and complete the locking. The entire locking process takes less time, and the locking force is symmetrical and uniform, forming a stable locking effect. This avoids the cutting blade from shifting due to vibration of the main shaft when cutting the plate, and the flatness of the hollow board cutting cut can be effectively controlled, which effectively ensures the cutting accuracy and improves the consistency of product quality.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1 to 3 A durable cutting device for a hollow board production line includes: a frame beam 1, with frame ears 11 fixedly connected to both ends of the frame beam 1, a main shaft 2 provided in the frame beam 1, with both ends of the main shaft 2 rotatably connected to the two frame ears 11 respectively, a multi-groove shaft cylinder 21 fixedly connected to the main shaft 2, the multi-groove shaft cylinder 21 having multiple mounting grooves, and a cutter 3 installed in each of the multiple mounting grooves; and an automatic adjustment mechanism, including a side frame 4, the side frame 4 being fixedly connected to one end of the frame beam 1, a gear ring 41 fixedly connected to one end of the main shaft 2, a rack 42 provided on the rear side of the gear ring 41, the rack 42 meshing with the gear ring 41, and a control component provided between the rack 42 and the side frame 4.

[0023] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the multiple mounting slots are arranged in an equidistant ring.

[0024] It should be noted that: the rack 42 moves synchronously with the drive block 43, thereby driving the gear ring 41 meshing with it to rotate. The gear ring 41 drives the main shaft 2 to rotate between the two frame ears 11. The multi-groove shaft cylinder 21 on the main shaft 2 rotates synchronously, thereby driving the cutters 3 in multiple mounting slots to rotate alternately to adjust the working angle of the cutters 3, completing the automatic adjustment of the angle of the cutters 3. The machine can enter the cutting plate operation state without stopping the machine to load and unload the cutters 3.

[0025] The equidistant annular mounting slots ensure that multiple cutters 3 are evenly distributed on the multi-groove cylinder 21, allowing for precise switching to the working position during rotation and adjustment.

[0026] refer to Figure 2 and Figure 3As shown, the control component includes a drive block 43, which is fixedly connected to a rack 42. Two vertical rods 44 are symmetrically fixedly connected in the side frame 4. The drive block 43 is slidably connected to the two vertical rods 44. An electric cylinder 45 is installed and connected at the upper end of the side frame 4. The output end of the electric cylinder 45 is fixedly connected to the drive block 43.

[0027] It should be noted that the electric cylinder 45 on the starter side frame 4 has its output end pushing the drive block 43 to slide stably along the two vertical rods 44. Since the drive block 43 is fixedly connected to the rack 42, it can directly and stably drive the rack 42 to move synchronously with the drive block 43.

[0028] refer to Figure 1 and Figure 2 As shown, both ends of the main shaft 2 are fixedly connected to side locking discs 5. Each side locking disc 5 is provided with multiple locking holes, which are arranged in an equidistant ring.

[0029] It should be noted that the main shaft 2 drives the side lock discs 5 on both sides to rotate, so that the different locks rotate to the locking position in sequence.

[0030] refer to Figure 2 As shown, both sides of the two side locking discs 5 are provided with locking plates 51, and each locking plate 51 is fixedly connected with a locking pin 52.

[0031] It should be noted that the locking pin 52 on the locking plate 51 moves synchronously with the locking plate 51 until the locking pin 52 is inserted into the corresponding lock slot on the side lock disc 5, thus completing the locking of the side lock disc 5.

[0032] refer to Figure 1 and Figure 2 As shown, a crossbeam 6 is fixedly connected to the rear side of the frame beam 1, and a crossbar 7 is fixedly connected between the crossbeams 6. Two locking plates 51 are slidably connected to the two ends of the crossbar 7 respectively.

[0033] It should be noted that the horizontal bar 7 is designed to ensure stable sliding of the two locking plates 51.

[0034] refer to Figure 2 As shown, a drive shaft 8 is rotatably connected between the crossbeams 6. A motor 81 is installed and connected to one end of the crossbeam 6. The output end of the motor 81 is fixedly connected to the drive shaft 8. The two ends of the drive shaft 8 are provided with threads in opposite directions. Both locking plates 51 are provided with threaded openings. The two locking plates 51 are respectively threaded to the two ends of the drive shaft 8.

[0035] It should be noted that the output end of the motor 81 drives the drive shaft 8 to rotate. Since the two ends of the drive shaft 8 are provided with threads in opposite directions, and the two locking plates 51 are respectively threaded to the two ends of the drive shaft 8, the drive shaft 8 can stably drive the two locking plates 51 to slide towards each other along the crossbar 7 when it rotates.

[0036] The working principle of the durable cutting device for a hollow board production line provided by this utility model is as follows: When it is necessary to adjust and replace different cutters 3, the electric cylinder 45 on the side frame 4 is activated. Its output end pushes the drive block 43 to slide stably along the two vertical rods 44. Since the drive block 43 is fixedly connected to the rack 42, the rack 42 moves synchronously with the drive block 43, thereby driving the gear ring 41 meshing with it to rotate. The gear ring 41 drives the main shaft 2 to rotate between the two frame ears 11. The multi-groove shaft cylinder 21 on the main shaft 2 rotates synchronously, thereby driving the cutters 3 in multiple mounting slots to rotate and alternately adjust the working angle of the cutters 3. After the angle of the cutter 3 reaches the preset position, the electric cylinder 45 stops working, completing the automatic adjustment of the angle of the cutter 3. The cutting operation can begin without stopping the machine to load and unload the cutters 3.

[0037] After the angle of the cutter 3 is adjusted, the motor 81 at one end of the crossbeam 6 is started. The output of the motor 81 drives the drive shaft 8 to rotate. Since the two ends of the drive shaft 8 have threads in opposite directions, and the two locking plates 51 are respectively threaded to the two ends of the drive shaft 8, when the drive shaft 8 rotates, it drives the two locking plates 51 to slide towards each other along the crossbar 7. The locking pins 52 on the locking plates 51 move synchronously with the locking plates 51 until the locking pins 52 are inserted into the corresponding locking holes on the side locking disc 5, thereby locking the side locking disc 5. Since the side locking disc 5 is fixedly connected to the main shaft 2, the main shaft 2 is firmly fixed, preventing the main shaft 2 from shifting due to vibration during the cutting process, and ensuring stable cutting operation.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
