Description

Technical Field

[0001] This application relates to the field of belt cutting, and in particular to a belt cutting device for fastening the center of a buckle. Background Technology

[0002] Currently, most conveyor systems used in mines are belt conveyors. During operation, damage often occurs at the fasteners of the conveyor belt, requiring timely cutting. Belt cutting devices, as key tools for belt maintenance, are of significant practical importance.

[0003] Traditional cutting devices use a hand-cranked drive wheel, which drives a gear to rotate. The gear meshes with a lead screw, which in turn rotates the blade. The blade is threaded onto the lead screw, thus moving the blade. However, the speed at which the hand-cranked drive wheel moves the blade is limited, and the force exerted by hand is unstable, often resulting in uneven and rough cuts on the belt. Especially when cutting thicker or harder belts, operators need to continuously crank the wheel for extended periods, consuming a lot of physical strength, and the cutting process is slow, leading to low overall work efficiency. Utility Model Content

[0004] To address the issues of excessive physical exertion, unstable force, uneven belt cuts, slow cutting process, and low work efficiency caused by operators manually cranking the transmission wheel for extended periods, this application provides a belt cutting device for fastening the buckle center.

[0005] The belt cutting device for fastening the center of a buckle provided in this application adopts the following technical solution: A belt cutting device for attaching buttons includes a support frame. Two receiving frames are symmetrically arranged on the inner side of the support frame. Slide plates slide on the receiving frames, and drive mechanisms are provided on the slide plates. Two pneumatic motors are fixed on one slide plate, and a first sprocket is fixed on each pneumatic motor. Two second sprockets rotate on the other slide plate. The first and second sprockets are connected by a chain meshing. A blade is fixed on the chain. Connecting plates are fixed on both sides of the receiving frames. Two sets of sliding mechanisms are provided on the receiving frames to move the receiving frames along the length direction of the support frame. The two receiving frames are fixedly connected by a fixing block. A button attaching machine is provided above the fixing block, and a rotating mechanism for changing the orientation of the button attaching machine is provided on the fixing block.

[0006] By adopting the above technical solution, a pneumatic motor drives the first sprocket to rotate. The first sprocket and the second sprocket are connected by a chain, which in turn moves the blades on the chain to cut the belt. Compared with the traditional hand-cranked method, the pneumatic motor can provide stable and efficient driving force, avoiding the physical exertion and instability caused by manual operation, and significantly improving cutting efficiency and cut smoothness.

[0007] Optionally, the sliding mechanism includes two rollers fixed on the support frame, a first positioning plate fixed on the connecting plate, and a first bolt threaded onto the first positioning plate. The two rollers rotate symmetrically on the support frame.

[0008] By adopting the above technical solution, the sliding mechanism enables the receiving frame to move stably on the support frame. The symmetrical rotation of the rollers reduces friction, making the movement of the receiving frame smoother. The cooperation between the first positioning plate and the first bolt allows for precise adjustment and fixation of the receiving frame's position, thereby ensuring the stability of the device during cutting and avoiding inaccurate cutting due to positional deviation.

[0009] Optionally, the rotating mechanism includes a rotating shaft that rotates on a fixed block, a mounting plate fixed on the rotating shaft, guide plates fixed at both ends of the mounting plate, a second positioning plate fixed on the guide plate, a second bolt threaded to the second positioning plate, and an abutment plate fixed on a receiving plate. The abutment plate is located below the second positioning plate. The two guide plates are fixed by a connecting rod, and the button fastener slides on the connecting rod.

[0010] By adopting the above technical solution, the rotating mechanism allows the button-attaching machine to flexibly adjust its position and angle. The mounting plate and the rotating shaft are rotatably connected, and the rotation of the button-attaching machine is achieved by rotating the mounting plate. The cooperation between the second positioning plate and the abutment plate, combined with the locking action of the second bolt, secures the button-attaching machine.

[0011] Optionally, the drive mechanism includes a cylinder, the bottom of which is fixed to a support frame, and the piston rod of which is fixed to a slide plate.

[0012] By adopting the above technical solution, the cylinder can drive the slide plate to move relative to the receiving frame, thereby driving the pneumatic motor and the blade to move as a whole, adjusting the cutting position, and thus adapting to cutting belts of different thicknesses.

[0013] Optionally, two fixing boxes are symmetrically arranged inside the receiving frame. Both ends of the fixing boxes are fixed to the slide plate, and the fixing boxes are sleeved on the chain.

[0014] By adopting the above technical solution, the fixing box can protect the chain, the part where the chain meshes with the first chain tooth, and the part where the chain meshes with the second chain tooth, preventing the chain from shifting or disengaging during high-speed operation, thereby improving the stability of the cutting process.

[0015] Optionally, the fixing box is provided with a first limiting groove, and the blade slides within the first limiting groove.

[0016] By adopting the above technical solution, the first limiting groove on the fixing box can precisely limit the movement trajectory of the blade, ensuring that the blade maintains a stable and straight movement path during cutting. At the same time, the setting of the first limiting groove can also reduce unnecessary friction between the blade and the fixing box, extending the service life of the blade.

[0017] Optionally, a limiting box is provided above the fixing box, and both ends of the limiting box are fixed to the receiving frame.

[0018] By adopting the above technical solution, the setting of the limiting box can restrict the space above the fixed box, effectively preventing the blade from shifting or shaking during the cutting process, thereby improving cutting accuracy and stability.

[0019] Optionally, the limiting box is provided with a second limiting groove for use with the blade.

[0020] By adopting the above technical solution, the second limiting groove opened on the limiting box can be used in conjunction with the blade to prevent the blade from deviating or shaking when moving at high speed, thereby ensuring a more stable and precise cutting process, improving cutting quality, and making the belt cut smoother.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By driving the chain between the first and second sprockets to rotate via a pneumatic motor, the blades are moved, achieving automated cutting, which significantly improves cutting efficiency and reduces the physical exertion of operators; 2. The sliding mechanism, through the cooperation of rollers, the first positioning plate, and the first bolt, can flexibly adjust the position of the receiving frame, so that the blade is accurately aligned with the cutting area of ​​the belt, thus improving the ease of operation of the device; 3. The rotating mechanism utilizes a rotating shaft, guide plate, second positioning plate, and second bolt to adjust the orientation of the button-attaching machine, facilitating adjustments to the machine's direction according to actual needs and enhancing the device's functional versatility and adaptability.

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses a belt cutting device for fastening the center of a buckle.

[0027] Reference Figure 1 A belt cutting device for fastening the center includes a support frame 1, two receiving frames 2 symmetrically arranged on the inner side of the support frame 1, a sliding plate 3 sliding inside the receiving frame 2, and a driving mechanism arranged between the sliding plate 3 and the receiving frame 2.

[0028] Reference Figure 1 Two sets of sliding mechanisms 10 are provided on the receiving frame 2 to move the receiving frame 2 along the length direction of the support frame 1. A fixing block 11 is fixed between the two receiving frames 2, and a button attaching machine 12 is provided above the fixing block 11. A rotating mechanism 13 for rotating the button attaching machine 12 is provided on the fixing block 11.

[0029] Reference Figure 2 The drive mechanism includes a cylinder 14, the bottom of which is fixed to the support frame 2, and the piston rod of the cylinder 14 is fixed to the slide plate 3. Activating the cylinder 14 causes the piston rod of the cylinder 14 to extend or retract, thereby driving the slide plate 3 to slide inside the support frame 2.

[0030] Reference Figure 3 Two pneumatic motors 4 are symmetrically fixed on one of the slide plates 3, and a first sprocket 5 is fixed on each of the two pneumatic motors 4. Two second sprockets 6 rotate on the other slide plate 3, and the first sprocket 5 and the second sprocket 6 are connected by a chain 7. A blade 8 is fixed on the chain 7.

[0031] Reference Figure 3 When the pneumatic motor 4 starts, it transmits power to the first sprocket 5, causing it to rotate. The first sprocket 5 and the second sprocket 6 are connected by a high-strength chain 7, which drives the chain 7 to move. A sharp blade 8 is fixed on the chain 7. As the chain 7 moves, the blade 8 can quickly cut the belt, greatly improving the cutting efficiency. Reference Figure 4 Two symmetrically arranged fixing boxes 15 are mounted inside the receiving frame 2. The fixing boxes 15 are perpendicular to the two sliding plates 3 and have high rigidity and wear resistance. Both ends of the fixing boxes 15 are firmly fixed to the sliding plates 3, and the fixing boxes 15 are sleeved on the chain 7. The fixing boxes 15 are provided with a first limiting groove 16, which restricts the blade 8 to slide precisely within the first limiting groove 16 during the cutting process, thereby ensuring high cutting precision.

[0032] Reference Figure 4 A limiting box 17 is provided above the fixing box 15. Both ends of the limiting box 17 are also fixed to the receiving frame 2. The limiting box 17 has high rigidity and wear resistance. A second limiting groove 18 is provided on the limiting box 17 for tight cooperation with the blade 8.

[0033] The first limiting groove 16 also restricts the movement trajectory of the blade 8. When the blade 8 moves to both ends of the first limiting groove 16, the first limiting groove 16 will block the blade 8 from continuing to move, and further cause the pneumatic motor 4 to stop running automatically.

[0034] Reference Figure 3 and Figure 4 When it is necessary to cut the buckles on the belt, first place the belt between the fixing box 15 and the limiting box 17, and adjust the position of the belt so that the buckles on the belt are positioned between the two blades 8. Start the cylinder 14, which in turn moves the slide plate 3 and the fixing box 15 upwards synchronously. Under the clamping of the fixing box 15 and the limiting box 17, the belt is fixed. Then, start the pneumatic motor 4. With the first toothed chain and the second toothed chain both meshing with the chain 7, the chain 7 drives the blades 8 to move. When the blades 8 move to the end of the first limiting groove 16, the first limiting groove 16 will block the further movement of the blades 8, causing the pneumatic motor 4 to automatically stop running, completing the cutting of the belt by the blades 8 and causing the blades 8 to automatically stop moving.

[0035] Reference Figure 1 and Figure 5 On both sides of the receiving frame 2, there are connecting plates 9 parallel to the chain 7. The sliding mechanism 10 includes two rollers 101, a first positioning plate 102, and a first bolt 103. The outer ring of the rollers 101 is made of polyurethane material, which has good wear resistance and shock absorption performance. Both rollers 101 are fixed on the receiving frame 2, and the two rollers 101 rotate symmetrically on both sides of the support frame 1, so that the rollers 101 move along the support frame 1. The first positioning plate 102 is fixed on the connecting plate 9, and the first bolt 103 is threadedly connected to the first positioning plate 102.

[0036] Reference Figure 5 When it is necessary to move the receiving frame 2 along the length of the support frame 1, first loosen the first bolt 103 so that it is detached from the surface of the support frame 1 and does not contact it. Then pull the receiving frame 2 to move it along the length of the support frame 1. After determining the specific moving position of the receiving frame 2, tighten the second bolt 1305 so that the first bolt 103 abuts against the surface of the support frame 1, thereby fixing the receiving frame 2 and preventing it from slipping during belt cutting, thus avoiding safety accidents. Reference Figure 6 The rotating mechanism 13 includes a rotating shaft 1301, a mounting plate 1302, and two guide plates 1303. The rotating shaft 1301 is fixed to the mounting plate, and the mounting plate 1302 rotates on the rotating shaft 1301. The two guide plates 1303 are respectively fixed to both ends of the mounting plate 1302, and a second positioning plate 1304 is fixed to the opposite side of each guide plate 1303. A second bolt 1305 is threaded onto each of the two second positioning plates 1304. An abutment plate 1306 is provided below the second positioning plate 1304 and is fixed to the receiving frame 2. The two guide plates 1303 are fixed by a connecting rod 1307, and the fastener 12 slides on the connecting rod 1307.

[0037] Reference Figure 6 When the orientation of the button-attaching machine 12 needs to be adjusted, loosen the second bolt 1305 so that it is no longer in contact with the abutment plate 1306, and then rotate the mounting plate 1302. Since both ends of the connecting rod 1307 are fixedly connected to the mounting plate 1302 through the guide plate 1303, rotating the mounting plate 1302 will also drive the connecting rod 1307 to rotate synchronously, thereby causing the button-attaching machine 12, which slides on the connecting rod 1307, to rotate synchronously as well. When the orientation of the button-attaching machine 12 is adjusted, tighten the second bolt 1305 so that it abuts against the abutment plate 1306, thus fixing the orientation of the button-attaching machine 12.

[0038] The implementation principle of a belt cutting device for buckle center according to an embodiment of this application is as follows: When the buckle of the belt is damaged and it is necessary to cut the buckle position, the cylinder 14 drives the slide plate 3 to slide within the receiving frame 2, adjusting the relative height between the blade 8 and the belt to adapt to belts of different thicknesses. Then, the pneumatic motor 4 is started, driving the first sprocket 5 to rotate. Under the meshing of the chain 7 and the second sprocket 6, the chain 7 is driven to rotate, thereby causing the blade 8 fixed on the chain 7 to move at high speed and quickly cut the belt.
