[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0019] This utility model is used for a conveyor belt joint cutting device, such as... Figure 1As shown, the device includes a cutting platform 100, with a cutting drive unit 200 connected to one side of the upper end face of the cutting platform 100. The cutting drive unit 200 includes a belt roll guide seat 210 installed on the upper end face of the cutting platform 100. A first lead screw slider assembly 220 and a pressure plate 230 are connected to the upper end face of the belt roll guide seat 210. One end of the pressure plate 230 is configured as an upwardly curved inclined plate structure. A hidden cutter part 300 that cooperates with the pressure plate 230 is connected to the first lead screw slider assembly 220. The cutting platform 100 is also provided with a transport belt pulling part 400 that cooperates with the cutting drive unit 200.

[0020] Furthermore, such as Figure 2 As shown, the cutting platform 100 includes a support frame 110 and a ramp 120 fixedly welded to the upper end of the support frame 110. A column bracket 130 is also fixedly welded to one end of the support frame 110. The column bracket 130 is used to place the belt roll. The conveyor belt pulling part 400 is set on the ramp 120.

[0021] like Figure 3 As shown, the inclined platform 120 includes a platform 121. One side of the platform 121 is connected to the support frame 110, and the platform 121 is set in an inclined manner. A baffle 122 is fixedly welded to the edge of the upper surface of the platform 121. No baffle 122 is set on the edge where the platform 121 connects to the support frame 110. A blade groove 123 that cooperates with the hidden cutting blade part 300 is also opened on the upper surface of one end of the platform 121.

[0022] Among them, the platform 121 is a component made of aluminum alloy. The surface of the aluminum alloy is smooth, which makes it easy for the cut conveyor belt to slide down automatically along the inclined platform 121. At the same time, one end of the baffle frame 122 is an unclosed structure, which allows the sliding conveyor belt to slide down from the platform 121.

[0023] The insert bracket 130 includes a bracket plate 131 welded to the support frame 110. The bracket plate 131 is located on the side near the cutter groove 123 and is arranged in the same direction as the cutter groove 123. A support seat 132 is welded on the bracket plate 131. An insert rod 133 is bolted to the support seat 132. The insert rod 133 is inclined and its inclination angle is the same as that of the platform 121. The belt roll guide seat 210 is arranged on the bracket plate 131.

[0024] The diameter of the insert rod 133 should be smaller than the inner diameter of the wood grain belt roller to facilitate the insertion of the insert rod 133 into the wood grain belt roller. The frame plate 131 has a reserved installation position for installing the belt roller guide seat 210.

[0025] Furthermore, such as Figures 4-6As shown, the belt roll guide seat 210 includes a seat block 211 mounted on the frame plate 131. The upper end face of the seat block 211 is inclined. A material support tongue plate 212 is welded to the side of the seat block 211 near the knife relief groove 123. The material support tongue plate 212 is located below the pressure strip plate 230. A distance is left between the end of the material support tongue plate 212 away from the seat block 211 and the knife relief groove 123. like Figure 7 , 8 As shown, a guide groove 201 is provided on the seat block 211. The guide groove 201 is located above the pressure strip plate 230. A rotating column 203 is rotatably installed at the upper end of the guide groove 201. An installation groove 202 is provided at the lower end of the guide groove 201. Several first springs 204 are vertically installed in the installation groove 202 and arranged in parallel. The upper ends of the several first springs 204 are connected to an upper abutment block 205. The upper abutment block 205 is movably arranged in the installation groove 202.

[0026] When the conveyor belt pulling part 400 pulls the free end of the wood grain belt roll to a fixed length, the straightened wood grain belt roll has a certain downward pressure, which causes the upper abutment block 205 to be pressed into the mounting groove 202. When the pulling of the free end of the wood grain belt roll stops, the downward pressure also disappears. Under the action of the first spring 204, the upper abutment block 205 is pushed out, so that the wood grain belt roll can be clamped between the upper abutment block 205 and the rotating column 203.

[0027] It should be noted that one end of the pressure plate 230 is configured as an upward-curving inclined plate structure. When the concealed cutter part 300 moves to this position, the upper end of the movable cutter head of the concealed cutter part 300 no longer contacts the pressure plate 230, and the pressure plate 230 cannot press down on the movable cutter head, so that the movable cutter head can retract and be hidden for protection.

[0028] Furthermore, such as Figure 9 As shown, the first lead screw and slider assembly 220 includes a U-shaped frame 221 that is bolted to the upper end of the seat block 211. The upper end of the U-shaped frame 221 is connected to a first electric lead screw 222. The first electric lead screw 222 is arranged parallel to the upper end surface of the seat block 211. A first slider 223 is threaded on the first electric lead screw 222. The first slider 223 is connected to the hidden cutter part 300.

[0029] The U-shaped frame 221 is bolted to the upper end of the seat block 211, which facilitates disassembly. During maintenance and repair work, it is convenient to disassemble the first lead screw slider assembly 220 as a whole, which facilitates the maintenance work.

[0030] The concealed cutting section 300 includes a reinforcing rod 310. One end of the reinforcing rod 310 is mounted on the first slider 223 by bolts, and the other end of the reinforcing rod 310 is connected to a telescopic blade 320. The telescopic blade 320 is located directly below the pressure plate 230, and the blade groove 123, the telescopic blade 320 and the pressure plate 230 are on the same straight line.

[0031] The reinforcing rod 310 and the telescopic blade 320 are detachably connected, achieving modularity and facilitating disassembly and replacement of both.

[0032] The width of the blade groove 123 is matched with the thickness of the movable blade head of the concealed cutter 300. When the slider of the first lead screw slider assembly 220 drives the concealed cutter 300 to move and cut the conveyor belt, the pressure plate 230 presses down on the upper end of the movable blade head of the concealed cutter 300, so that the movable blade head can move down into the blade groove 123, thus protecting the movable blade head.

[0033] Furthermore, such as Figure 10 As shown, the telescopic blade 320 includes a retractable blade housing 321, with a cover 322 detachably mounted on its surface. The retractable blade housing 321 is connected to a reinforcing rod 310. A blade body 323 is inserted into the blade groove of the retractable blade housing 321. Lugs 301, which mate with the reinforcing rod 310, are connected to both sides of the retractable blade housing 321. Positioning grooves 302 are formed on both sides of the blade groove of the blade housing 321. The lower end of the blade body 323 is configured as an edge-cutting section 303. Protrusions 304 are welded to both sides of the upper end of the blade body 323. The two protrusions 304 are movably disposed within the positioning grooves 302. Second springs 305 are fixedly connected to the two protrusions 304. The lower ends of the second springs 305 are connected to the inner wall of the positioning grooves 302 in the retractable blade housing 321. Figure 11 As shown, mounting recesses 306 are respectively provided on both sides of the upper end of the blade body 323, and pulleys 307 are respectively provided in the two mounting recesses 306. The pulleys 307 are in contact with the bottom surface of the pressure plate 230.

[0034] The mounting notches 306 can be opened on both sides of the upper end of the blade body 323. One set or two sets can be opened. When the first lead screw slider assembly 220 drives the hidden cutting part 300 to move past the inclined plate structure of the pressure plate 230, the upper end of the blade body 323 contacts the pressure plate 230. The pressure plate 230 presses down on the upper end of the blade body 323. The blade body 323 continues to move. The contact between the pulley 307 and the pressure plate 230 can greatly reduce the friction, making the movement smoother and reducing the wear between the pressure plate 230 and the upper end of the blade body 323.

[0035] The conveyor belt pulling part 400 is installed on the inclined platform 120 for pulling the free end of the belt roll to a fixed length.

[0036] Furthermore, such as Figure 12 As shown, the conveyor belt pulling part 400 includes a second lead screw slider assembly 410, which is connected to a support frame rod 420. A clamping frame 430 is installed on the support frame rod 420. Both the second lead screw slider assembly 410 and the clamping frame 430 are arranged on the inclined platform 120.

[0037] The second lead screw and slider assembly 410 includes two L-shaped frames 411 mounted on the baffle frame 122. A second electric lead screw 412 is vertically connected to both L-shaped frames 411. A second slider 413 is threaded through the second electric lead screw 412. The support frame rod 420 includes a cross frame rod 421 detachably connected to the second slider 413 by bolts. The cross frame rod 421 is vertically arranged with the L-shaped frames 411 and the second electric lead screw 412. A support wheel rod 422 is vertically connected to the end of the cross frame rod 421 away from the second electric lead screw 412. The lower end of the support wheel rod 422 contacts the platform 121. The clamping frame 430 includes an L-shaped plate 431 welded to the lower end face of the crossbar 421. The vertical plate of the L-shaped plate 431 is connected to the crossbar 421. A shovel head structure is provided at the lower end of the horizontal plate of the L-shaped plate 431. A supporting straight plate 432 is welded to the vertical plate of the L-shaped plate 431. An electric telescopic rod 433 is fixed to the supporting straight plate 432. The telescopic end of the electric telescopic rod 433 passes through the supporting straight plate 432 and is connected to a pressure rod 434. Positioning posts 435 are vertically connected to both sides of the upper end face of the pressure rod 434. The two positioning posts 435 respectively movably pass through both ends of the supporting straight plate 432. The crossbar 421 is arranged parallel to the first electric lead screw 222.

[0038] The shovel head structure at the lower horizontal plate of the L-shaped plate 431 facilitates the shoveling of the conveyor belt on the material support tongue 212. After the conveyor belt is shoveled into the horizontal plate of the L-shaped plate 431, the telescopic end of the electric telescopic rod 433 drives the pressure rod 434 to move down, clamping and fixing the conveyor belt. The positioning post 435 makes the movement of the pressure rod 434 more stable. After the conveyor belt is clamped and fixed, the second screw slider assembly 410 drives the support frame rod 420 to move, pulling the conveyor belt to the required cutting length and then stopping the movement, thus realizing the fixed-length cutting of the conveyor belt.

[0039] As shown above, there is a distance between the end of the material support tongue 212 and the cutting groove 123. When the conveyor belt is cut along the cutting groove 123, a reserved length of conveyor belt will hang down along the end of the material support tongue 212, which makes it easier for the shovel head structure at the lower horizontal plate of the L-shaped plate 431 to shovel into the hanging conveyor belt, making it easier to clamp the conveyor belt.

[0040] This utility model relates to a conveyor belt joint cutting device and its usage method. The concealed cutting blade 300 can protect the blade, and the conveyor belt pulling part 400 can pull the free end of the belt roll to a fixed length. Compared with the manual cutting method, the cut end face of the belt cut by this cutting device is more neat, and the cut conveyor belt can automatically slide down from the inclined platform 120 for collection.

[0041] Working principle: Insert the insert rod 133 into the wood grain belt roller. One end of the belt passes through the gap between the upper abutment block 205 and the rotating column 203, and is then fixed by the lower horizontal plate of the L-shaped plate 431 and the pressure rod 434. After the conveyor belt is clamped and fixed, the second electric screw 412 rotates to drive the support frame rod 420 to move, pulling the conveyor belt to the required cutting length and then stopping to achieve fixed-length cutting of the conveyor belt. Subsequently, the first electric screw 222 drives the hidden cutting part 300 to move through the first slider 223. Under the pressure of the pressure strip plate 230, the cutting edge 303 extends to cut the conveyor belt. There is a distance between the end of the material support tongue plate 212 and the cutting groove 123. After the conveyor belt is cut along the cutting groove 123, a reserved length of conveyor belt will hang down along the end of the material support tongue plate 212, which makes it easier for the shovel head structure at the lower horizontal plate of the L-shaped plate 431 to shovel into the hanging conveyor belt, making it easier to clamp the conveyor belt.

[0042] The blade body, with its lower end configured as an edge-opening section 303, is movably installed in the blade groove of the blade housing 321. Protrusions 304 on both sides of the blade body 323 are movably positioned within positioning grooves 302, and the lower ends of the second springs 305 on the protrusions 304 are connected to the positioning grooves 302. A pressure plate 230 is welded to one side of the belt conveyor guide seat 210. One end of the pressure plate 230 is configured as an upward-curving inclined plate structure. When the concealed cutting blade 300 moves to this position, the upper end of the movable blade head of the concealed cutting blade 300 no longer contacts the pressure plate 230, and the pressure plate 230 cannot contact the movable blade. The head is pressed down, allowing the movable blade head to retract and be hidden for protection. When the first lead screw slider assembly drives the hidden cutting part 300 to move past the inclined plate structure that is tilted upward by the pressure plate 0.0, the upper end of the blade body 323 contacts the pressure plate 230. The pressure plate 230 presses down on the upper end of the blade body 323, exposing the cutting edge 303 at the lower end of the blade body 323 and cutting the conveyor belt. The pressure plate 230 presses down on the blade body 323, eliminating the need for additional pressing drive equipment, thus saving energy. At the same time, compared with manual cutting, the cut end face of the belt cut by this cutting device is neater.

[0043] A shovel head structure is provided at the lower horizontal plate of the L-shaped plate 431 to facilitate shoveling the conveyor belt on the material support tongue 212. After the conveyor belt is shoveled into the horizontal plate of the L-shaped plate 431, the telescopic end of the electric telescopic rod 433 drives the pressure rod 434 to move down and clamp and fix the conveyor belt. The positioning post 435 makes the movement of the pressure rod 434 more stable.

[0044] Example 1 This embodiment is used for a conveyor belt joint cutting device, such as...

[0046] like Figure 3 As shown, the inclined platform 120 includes a platform 121. One side of the platform 121 is connected to the support frame 110, and the platform 121 is set in an inclined manner. A baffle 122 is fixedly welded to the edge of the upper surface of the platform 121. No baffle 122 is set on the edge where the platform 121 connects to the support frame 110. A blade groove 123 that cooperates with the hidden cutting blade part 300 is also opened on the upper surface of one end of the platform 121.

[0047] Among them, the platform 121 is a component made of aluminum alloy. The surface of the aluminum alloy is smooth, which makes it easy for the cut conveyor belt to slide down automatically along the inclined platform 121. At the same time, one end of the baffle frame 122 is an unclosed structure, which allows the sliding conveyor belt to slide down from the platform 121.

[0048] The insert bracket 130 includes a bracket plate 131 welded to the support frame 110. The bracket plate 131 is located on the side near the cutter groove 123 and is arranged in the same direction as the cutter groove 123. A support seat 132 is welded on the bracket plate 131.

The belt roll guide seat 210 is arranged on the bracket plate 131.

[0049] The diameter of the insert rod 133 should be smaller than the inner diameter of the wood grain belt roller to facilitate the insertion of the insert rod 133 into the wood grain belt roller. The frame plate 131 has a reserved installation position for installing the belt roller guide seat 210.

[0050] Example 3 This embodiment of the conveyor belt joint cutting device is based on the structure of Embodiment 2, and further includes, for example... Figures 4-6 As shown, the belt roll guide seat 210 includes a seat block 211 mounted on the frame plate 131. The upper end face of the seat block 211 is inclined. A material support tongue plate 212 is welded to the side of the seat block 211 near the knife relief groove 123. The material support tongue plate 212 is located below the pressure strip plate 230. A distance is left between the end of the material support tongue plate 212 away from the seat block 211 and the knife relief groove 123. like Figure 7 , 8 As shown, a guide groove 201 is provided on the seat block 211. The guide groove 201 is located above the pressure strip plate 230. A rotating column 203 is rotatably installed at the upper end of the guide groove 201. An installation groove 202 is provided at the lower end of the guide groove 201. Several first springs 204 are vertically installed in the installation groove 202 and arranged in parallel. The upper ends of the several first springs 204 are connected to an upper abutment block 205. The upper abutment block 205 is movably arranged in the installation groove 202.

[0051] When the conveyor belt pulling part 400 pulls the free end of the wood grain belt roll to a fixed length, the straightened wood grain belt roll has a certain downward pressure, which causes the upper abutment block 205 to be pressed into the mounting groove 202. When the pulling of the free end of the wood grain belt roll stops, the downward pressure also disappears. Under the action of the first spring 204, the upper abutment block 205 is pushed out, so that the wood grain belt roll can be clamped between the upper abutment block 205 and the rotating column 203.

[0052] It should be noted that one end of the pressure plate 230 is configured as an upward-curving inclined plate structure. When the concealed cutter part 300 moves to this position, the upper end of the movable cutter head of the concealed cutter part 300 no longer contacts the pressure plate 230, and the pressure plate 230 cannot press down on the movable cutter head, so that the movable cutter head can retract and be hidden for protection.

[0053] Example 4 This embodiment of the conveyor belt joint cutting device is based on the structure of embodiment 3, and further includes, for example... Figure 9 As shown, the first lead screw and slider assembly 220 includes a U-shaped frame 221 that is bolted to the upper end of the seat block 211. The upper end of the U-shaped frame 221 is connected to a first electric lead screw 222. The first electric lead screw 222 is arranged parallel to the upper end surface of the seat block 211. A first slider 223 is threaded on the first electric lead screw 222. The first slider 223 is connected to the hidden cutter part 300.

[0054] The U-shaped frame 221 is bolted to the upper end of the seat block 211, which facilitates disassembly. During maintenance and repair work, it is convenient to disassemble the first lead screw slider assembly 220 as a whole, which facilitates the maintenance work.

[0055] Example 5 Based on the structure of Embodiment 4, the conveyor belt joint cutting device in this embodiment further includes a hidden cutting section 300, which includes a reinforcing rod 310. One end of the reinforcing rod 310 is bolted to the first slider 223, and the other end of the reinforcing rod 310 is connected to a telescopic blade 320. The telescopic blade 320 is located directly below the pressure plate 230, and the blade groove 123, the telescopic blade 320, and the pressure plate 230 are on the same straight line.

[0056] The reinforcing rod 310 and the telescopic blade 320 are detachably connected, achieving modularity and facilitating disassembly and replacement of both.

[0057] The width of the blade groove 123 is matched with the thickness of the movable blade head of the concealed cutter 300. When the slider of the first lead screw slider assembly 220 drives the concealed cutter 300 to move and cut the conveyor belt, the pressure plate 230 presses down on the upper end of the movable blade head of the concealed cutter 300, so that the movable blade head can move down into the blade groove 123, thus protecting the movable blade head.

[0058] Example 6 This embodiment of the conveyor belt joint cutting device is based on the structure of embodiment 5, and further includes, for example... Figure 10As shown, the telescopic blade 320 includes a retractable blade housing 321, with a cover 322 detachably mounted on its surface. The retractable blade housing 321 is connected to a reinforcing rod 310. A blade body 323 is inserted into the blade groove of the retractable blade housing 321. Lugs 301, which mate with the reinforcing rod 310, are connected to both sides of the retractable blade housing 321. Positioning grooves 302 are formed on both sides of the blade groove of the blade housing 321. The lower end of the blade body 323 is configured as an edge-cutting section 303. Protrusions 304 are welded to both sides of the upper end of the blade body 323. The two protrusions 304 are movably disposed within the positioning grooves 302. Second springs 305 are fixedly connected to the two protrusions 304. The lower ends of the second springs 305 are connected to the inner wall of the positioning grooves 302 in the retractable blade housing 321. Figure 11 As shown, mounting recesses 306 are respectively provided on both sides of the upper end of the blade body 323, and pulleys 307 are respectively provided in the two mounting recesses 306. The pulleys 307 are in contact with the bottom surface of the pressure plate 230.

[0059] The mounting notches 306 can be opened on both sides of the upper end of the blade body 323. One set or two sets can be opened. When the first lead screw slider assembly 220 drives the hidden cutting part 300 to move past the inclined plate structure of the pressure plate 230, the upper end of the blade body 323 contacts the pressure plate 230. The pressure plate 230 presses down on the upper end of the blade body 323. The blade body 323 continues to move. The contact between the pulley 307 and the pressure plate 230 can greatly reduce the friction, making the movement smoother and reducing the wear between the pressure plate 230 and the upper end of the blade body 323.

[0060] Example 7 This embodiment of the conveyor belt joint cutting device is based on the structure of embodiment 6, and further includes, for example... Figure 12 As shown, the conveyor belt pulling part 400 includes a second lead screw slider assembly 410, which is connected to a support frame rod 420. A clamping frame 430 is installed on the support frame rod 420. Both the second lead screw slider assembly 410 and the clamping frame 430 are arranged on the inclined platform 120.

[0061] The second lead screw and slider assembly 410 includes two L-shaped frames 411 mounted on the baffle frame 122. A second electric lead screw 412 is vertically connected to both L-shaped frames 411. A second slider 413 is threaded through the second electric lead screw 412. The support frame rod 420 includes a cross frame rod 421 detachably connected to the second slider 413 by bolts. The cross frame rod 421 is vertically arranged with the L-shaped frames 411 and the second electric lead screw 412. A support wheel rod 422 is vertically connected to the end of the cross frame rod 421 away from the second electric lead screw 412. The lower end of the support wheel rod 422 contacts the platform 121. The clamping frame 430 includes an L-shaped plate 431 welded to the lower end face of the crossbar 421. The vertical plate of the L-shaped plate 431 is connected to the crossbar 421. A shovel head structure is provided at the lower end of the horizontal plate of the L-shaped plate 431. A supporting straight plate 432 is welded to the vertical plate of the L-shaped plate 431. An electric telescopic rod 433 is fixed to the supporting straight plate 432. The telescopic end of the electric telescopic rod 433 passes through the supporting straight plate 432 and is connected to a pressure rod 434. Positioning posts 435 are vertically connected to both sides of the upper end face of the pressure rod 434. The two positioning posts 435 respectively movably pass through both ends of the supporting straight plate 432. The crossbar 421 is arranged parallel to the first electric lead screw 222.

[0062] The shovel head structure at the lower horizontal plate of the L-shaped plate 431 facilitates the shoveling of the conveyor belt on the material support tongue 212. After the conveyor belt is shoveled into the horizontal plate of the L-shaped plate 431, the telescopic end of the electric telescopic rod 433 drives the pressure rod 434 to move down, clamping and fixing the conveyor belt. The positioning post 435 makes the movement of the pressure rod 434 more stable. After the conveyor belt is clamped and fixed, the second screw slider assembly 410 drives the support frame rod 420 to move, pulling the conveyor belt to the required cutting length and then stopping the movement, thus realizing the fixed-length cutting of the conveyor belt.
