[0056] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] See also Figures 1 to 8 As shown, a galvanized sheet cutting platform for fire door production includes a roller conveyor line 1 for conveying the galvanized sheet;

[0058] The rear end of the roller conveyor line 1 is provided with a limit plate 2 for blocking the galvanized sheet;

[0059] A vertical positioning plate 3 is provided on the left side of the roller conveyor line 1, and a positioning drive mechanism 4 for intermittently pushing the galvanized sheet toward the positioning plate 3 is provided on the right side of the roller conveyor line 1;

[0060] The left side of the roller conveyor line 1 is also provided with a clamping mechanism 5 that can adaptively clamp and fix the galvanized sheet when the galvanized sheet rests on the positioning plate 3;

[0061] A material unloading mechanism 6 for pushing the galvanized sheet after cutting to the rear end of the roller conveyor line 1 is provided on the left side of the front end of the roller conveyor line 1 .

[0062] Galvanized sheets are generally rectangular sheets. When the galvanized sheets need to be cut, the staff or a special loading device will place the galvanized sheets on the front end of the roller conveyor line 1. At this time, under the transportation of the roller conveyor line 1 (it should be noted that the roller conveyor line is an existing conveying mechanism, that is, the objects on the roller conveyor line 1 are driven to move by the synchronous rotation of multiple rollers. For the specific structure and operation principle of the roller conveyor line 1, please refer to the existing technology and will not be described in detail here), the galvanized sheets can be transported from the front end of the roller conveyor line 1 to the rear end of the roller conveyor line 1, so that the galvanized sheets are against the limit plate 2. The galvanized sheet is then pushed toward the positioning plate 3 by the positioning drive mechanism 4, so that the galvanized sheet is also against the positioning plate 3. Since the left side of the roller conveyor line 1 is also provided with a clamping mechanism 5 that can adaptively clamp and fix the galvanized sheet when the galvanized sheet is against the positioning plate 3, the galvanized sheet is continuously approached to the positioning plate 3 during the operation of the positioning drive mechanism 4. The clamping mechanism 5 can adaptively clamp and fix the galvanized sheet when the galvanized sheet is continuously approaching the positioning plate 3. The galvanized sheet cutting work platform also includes a laser cutting machine for cutting the galvanized sheet. The laser The cutting machine is located above the roller conveyor line 1. The laser cutting machine is a prior art and is not shown in the figure. The specific working principle of the laser cutting machine will not be described here. After the galvanized sheet is clamped and fixed by the clamping mechanism 5, the laser cutting machine cuts a part of the galvanized sheet near the positioning plate 3. After a part of the galvanized sheet near the positioning plate 3 is cut off, the unloading mechanism 6 pushes the cut galvanized sheet to the rear end of the roller conveyor line 1. At this time, the staff standing at the rear end of the roller conveyor line 1 can pull out and remove the galvanized sheet after cutting. When the cut galvanized sheet is removed from the roller conveyor line 1 After removal, the uncut galvanized sheet still on the roller conveyor line 1 is at a certain distance from the positioning plate 3. Therefore, the uncut galvanized sheet is not close to the positioning plate 3, so that the clamping mechanism 5 can be reset to its initial state. Because the positioning drive mechanism 4 can intermittently push the galvanized sheet toward the positioning plate 3, at this time, under the action of the positioning drive mechanism 4, the galvanized sheet can be pushed toward the positioning plate 3 again and rest against the positioning plate 3. At this time, the clamping mechanism 5 adaptively clamps and fixes the galvanized sheet again, and reciprocates in sequence to completely cut and remove the galvanized sheet.

[0063] See also Figures 1 to 5 As shown, the clamping mechanism 5 includes two mounting shells 51;

[0064] The positioning plate 3 is provided with two mounting grooves 31 running through both ends thereof. The two mounting grooves 31 are located at the same height and are respectively located at the front and rear ends of the roller conveyor line 1;

[0065] The two mounting shells 51 are fixedly mounted on the end of the positioning plate 3 away from the roller conveyor line 1 and the two mounting grooves 31 are respectively connected to the inner cavity of the two mounting shells 51;

[0066] Each mounting shell 51 is provided with two horizontally arranged clamping plates 52, and the two clamping plates 52 are mirror-imaged on the upper and lower sides of the galvanized plate. Each mounting shell 51 is also provided with a driving component 53 for driving the two clamping plates 52 to move toward each other.

[0067] By providing a driving component 53, the two clamping plates 52 can be driven to move toward each other, so that the two clamping plates 52 fix the galvanized sheet. By respectively arranging the two mounting shells 51 at the two ends of the roller conveyor line 1, each mounting shell 51 is provided with two clamping plates 52 and a driving component 53 for driving the two clamping plates 52 to move toward each other, so that the clamping mechanism 5 can clamp the galvanized sheet at the same time from both ends of the roller conveyor line 1, thereby effectively increasing the clamping effect of the clamping mechanism 5.

[0068] See also Figure 1 、 Figures 4 to 6 As shown, each set of driving components 53 includes a vertical plate 531, a slider 532, two bar-shaped connecting rods 533, two first connecting rods 534 and two second connecting rods 535;

[0069] The vertical plate 531 is fixedly installed in the mounting shell 51, and the length direction of the vertical plate 531 is perpendicular to the running direction of the roller conveyor line 1;

[0070] One end of the vertical plate 531 is provided with a first sliding groove 5311 arranged horizontally and a second sliding groove 5312 arranged vertically, and the first sliding groove 5311 and the second sliding groove 5312 are arranged crosswise;

[0071] The slider 532 is slidably arranged in the first slide groove 5311. The two bar-shaped connecting rods 533 are horizontally arranged along the length direction of the vertical plate 531 and are respectively located on the upper and lower sides of the slider 532. The two bar-shaped connecting rods 533 are fixedly connected to a protrusion 5331 that slides in cooperation with the second slide groove 5312. The two clamping plates 52 are respectively installed at one end of the two bar-shaped connecting rods 533 close to the roller conveyor line 1.

[0072] The two first connecting rods 534 are arranged in parallel, one end of each of the two first connecting rods 534 is hinged to the slider 532, and the other end of each of the two first connecting rods 534 is hinged to the bar-shaped connecting rod 533 located above the slider 532;

[0073] The two second connecting rods 535 are arranged in parallel, one end of each of the two second connecting rods 535 is hinged to the slider 532 , and the other end of each of the two second connecting rods 535 is hinged to the bar-shaped connecting rod 533 located below the slider 532 .

[0074] When the distance between the two clamping plates 52 reaches its maximum value, the two bar connecting rods 533 are respectively located at the two ends of the second sliding groove 5312, and the angle between the first connecting rod 534 and the second connecting rod 535 close to the roller conveyor line 1 is an acute angle. At this time, when the slider 532 slides in the first sliding groove 5311 in the direction away from the roller conveyor line 1, the angle between the first connecting rod 534 and the second connecting rod 535 close to the roller conveyor line 1 gradually decreases, because the two bar connecting rods 533 are fixedly connected to the top of the second sliding groove 5312 with the protrusion 5331 slidingly matched. Therefore, driven by the first connecting rod 534 and the second connecting rod 535, the two bar connecting rods 533 will approach each other, thereby driving the clamping plates 52 to approach each other, so as to achieve fixed clamping of the galvanized sheet by the clamping plates 52. When the slider 532 slides in the first slide groove 5311 toward the direction close to the roller conveyor line 1, the angle between the first connecting rod 534 and the second connecting rod 535 on the side close to the roller conveyor line 1 gradually increases. Driven by the first connecting rod 534 and the second connecting rod 535, the two bar connecting rods 533 move away from each other, thereby driving the clamping plates 52 move away from each other.

[0075] See also Figure 1 、 Figures 3 to 5 As shown, each slider 532 is fixedly connected to a horizontally arranged round rod 5321 at one end close to the roller conveyor line 1, a pressing block 536 is fixedly installed at the end of the round rod 5321, and a connecting plate 537 is fixedly connected between the two pressing blocks 536;

[0076] Each slider 532 is fixedly connected to a guide rod 5322 at one end away from the roller conveyor line 1. A spring 538 is provided on the guide rod 5322. The end of the guide rod 5322 passes through the shell of the mounting shell 51 to its outside. The spring 538 is located inside the mounting shell 51.

[0077] Under the action of spring 538, spring 538 drives slider 532 to slide in the first slide groove 5311 toward the side close to roller conveyor line 1. When spring 538 is fully in the extended state, slider 532 is located at one end of the first slide groove 5311 close to roller conveyor line 1. In this process, round rod 5321 moves with slider 532. Finally, round rod 5321 drives pressing block 536 to move toward the direction close to roller conveyor line 1. The movement of two pressing blocks 536 can drive connecting plate 537 to move toward roller conveyor line 1. The galvanized sheet moves in the direction of the roller conveyor line 1. At this time, the positioning drive mechanism 4 drives the galvanized sheet to move in the direction of the connecting plate 537. When the galvanized sheet contacts the connecting plate 537, the positioning drive mechanism 4 continues to operate, thereby the connecting plate 537 and the two pressure plates move in the direction away from the roller conveyor line 1 under the action of the positioning drive mechanism 4, thereby driving the slider 532 to slide along the first slide groove 5311 in the direction away from the roller conveyor line 1, thereby making the two clamping plates 52 approach each other, thereby achieving fixed clamping of the galvanized sheet.

[0078] See also Figure 1 and Figure 4 and Figure 5 As shown, a limiting block 539 for limiting the sliding block 532 is further provided in the first sliding groove 5311 on each vertical plate 531 . The limiting block 539 is located at one end of the first sliding groove 5311 close to the roller conveyor line 1 .

[0079] By further arranging a limit block 539 in the first slide groove 5311, when the slider 532 slides along the first slide groove 5311 toward the direction close to the roller conveyor line 1 under the action of the spring 538, the slider 532 will eventually abut against the limit block 539 to prevent the slider 532 from sliding out of the first slide groove 5311. When the slider 532 abuts against the limit block 539, the spring 538 is in a fully extended state, and the two clamping plates 52 are in an open state.

[0080] See also Figure 1 、 Figures 3 to 5 As shown, a plurality of rectangular through slots 5371 are formed on the connecting plate 537, and a roller 5372 is provided in each rectangular through slot 5371 for rotation in the vertical direction;

[0081] A plurality of universal ball bearings 5361 are installed on the inner side of each clamping plate 52 .

[0082] When the galvanized sheet slides toward the connecting plate 537, the galvanized sheet will rest against multiple rollers 5372, and the galvanized sheet will press against the rollers 5372 to drive the connecting plate 537 to move in the direction away from the roller conveyor line 1. When the two opposite clamping plates 52 approach each other, the universal ball 5361 on each clamping plate 52 will rest against the galvanized sheet, and the galvanized sheet will be clamped by the universal ball 5361 on the two clamping plates 52. When one end of the galvanized sheet close to the connecting plate 537 is cut off, the galvanized sheet after cutting is still clamped by the two clamping plates 52. At this time, the unloading mechanism 6 will push the cut galvanized sheet to the rear end of the roller conveyor line 1. In the process again, the cut galvanized sheet can be placed on the rollers 5372 and the universal ball 5361, so that the galvanized sheet is extended to the end of the roller conveyor line 1, and then the staff can easily pull out the galvanized sheet after cutting. When the galvanized sheet after cutting is completely separated from the clamping plate 52 and the roller 5372, the two relative clamping plates 52 can be opened under the action of the spring 538, and the connecting plate 537 is also reset to its original position. The roller 5372 and the universal ball 5361 are provided to facilitate the sliding of the galvanized sheet after cutting to the end of the roller conveyor line 1, avoiding excessive friction between the clamping plate 52 and the galvanized sheet, which makes it impossible to unload the galvanized sheet smoothly. At the same time, it can also effectively reduce the wear of the clamping plate 52 and the galvanized sheet, and reduce production waste to a certain extent.

[0083] See also Figure 1 and Figure 2 As shown, a strip stone plate 11 is fixedly installed at the upper end of the roller conveyor line 1 and near the connecting plate 537.

[0084] The strip stone plate 11 is located on the frame of the roller conveyor line 1, and the laser source of the laser cutting machine will irradiate the strip stone plate 11 after cutting the galvanized plate. Because the laser source cannot cause damage to the strip stone plate 11, the laser cutting machine is prevented from causing damage to the roller conveyor line 1.

[0085] See also Figure 1 and Figure 2 As shown, the limiting plate 2 is located at the right end of the roller conveyor line 1.

[0086] When the galvanized sheet rests on the limit plate 2, the right end of the galvanized sheet rests on the limit plate 2, and the left end of the galvanized sheet does not rest on the limit plate 2. When the galvanized sheet is cut by the laser cutting machine, the cut galvanized sheet is not blocked by the limit plate 2, so the galvanized sheet can be pushed for unloading through the unloading mechanism 6.

[0087] See also Figure 1 and Figure 7 As shown, the blanking mechanism 6 includes a linear slide 61 and a push block 62;

[0088] The linear slide 61 is arranged at the left end of the roller conveyor line 1 , and the length direction of the linear slide 61 is consistent with the length direction of the roller conveyor line 1 . The pushing block 62 is vertically arranged on the execution part of the linear slide 61 .

[0089] When the linear slide 61 is in the initial state, the pushing block 62 is located at the head end of the roller conveyor line 1, and the top surface of the pushing block 62 is higher than the upper end surface of the galvanized sheet on the roller conveyor line 1. When the galvanized sheet is transported along the roller conveyor line 1 to the end of the roller conveyor line 1, the galvanized sheet is completely located directly above the roller conveyor line 1 and will not be blocked by the pushing block 62. After the galvanized sheet rests on the limit plate 2, under the action of the positioning drive mechanism 4, the galvanized sheet will be pushed to the left side of the roller conveyor line 1 and slide in the direction of the positioning plate 3. After the galvanized sheet is fixedly clamped by the clamping mechanism 5, the left end of the galvanized sheet is located at the rear side of the pushing block 62. When it is necessary to unload the galvanized sheet after cutting, the linear slide 61 runs, and under the drive of the linear slide 61, the pushing block 62 will slide toward the end of the roller conveyor line 1. As a result, the cut galvanized sheet will be pushed by the pushing block 62 to slide toward the end of the roller conveyor line 1, thereby realizing the unloading of the galvanized sheet.

[0090] See also Figure 1 and Figure 8 As shown, the positioning drive mechanism 4 includes a table frame 41, a screw rod 42, a rotation driver 43 and two guide rods 44. A vertically arranged strip plate 411 is provided at the upper end of the table frame 41;

[0091] The two guide rods 44 are both horizontally arranged and slidably arranged on the strip plate 411. One end of each guide rod 44 is fixedly connected to a push plate 45, which is located between the strip plate 411 and the positioning plate 3. The other end of the two guide rods 44 is fixedly connected to a mounting plate 46, which is located on the side of the strip plate 411 away from the positioning plate 3.

[0092] The screw rod 42 is located on a side of the strip plate 411 away from the positioning plate 3 and is arranged parallel to the guide rod 44. One end of the screw rod 42 is rotatably arranged on the strip plate 411, and the other end of the screw rod 42 is threadedly connected to the mounting plate 46.

[0093] The rotary driver 43 is fixed on the table frame 41 via a motor bracket, and the output shaft of the rotary driver 43 is transmission-connected to the screw rod 42 via a coupling.

[0094] When the rotary driver 43 is running, it can drive the screw rod 42 to rotate, so that the mounting plate 46 can slide along the length direction of the screw rod 42. When the mounting plate 46 slides in the direction close to the strip plate 411, the two push plates 45 can be driven by the guide rod 44 to move in the direction close to the positioning plate 3. As a result, the galvanized plate can be pushed to slide in the direction of the positioning plate 3 under the drive of the push plates 45. It should be noted that each push plate 45 is located between two adjacent rollers on the roller conveyor line 1, and the lower end surface of the push plate should be higher than the height of the top of the roller conveyor line 1. The forward and reverse rotation of the rotary driver 43 can drive the screw rod 42 to reverse, so that the push plate 45 slides in the direction close to the positioning plate 3 or slides in the direction away from the positioning plate 3.

[0095] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
