When the sliding feeding unit passes through the circular saw blade 2, the circular saw blade 2 completes the cutting process of the plates.

[0047] like Figures 1 to 4 As shown, the sliding feeding unit is arranged on the cutting device 1, and the sliding feeding unit includes a first slide plate 41 and a second slide plate 42, the first slide plate 41 and the second slide plate 42 are both slidably assembled on the top surface of the cutting device 1, an avoidance gap 43 is formed between the first slide plate 41 and the second slide plate 42, and the first slide plate 41 and the second slide plate 42 are fixedly connected by two U-shaped connecting frames 44;

[0048] The push cylinder 5 is installed on the side plate 31, and a fixing block 6 is fixed to the bottom surface of the first slide plate 41, and the telescopic end of the push cylinder 5 is fixedly connected to the fixing block 6;

[0049] like Figures 1 to 4 As shown, the clamping unit is composed of a first clamping assembly, a second clamping assembly, a one-way locking assembly, a blocking assembly and a push assembly, the first clamping assembly is arranged on the first slide 41, the second clamping assembly is arranged on the second slide 42, the one-way locking assembly is also arranged on the second slide 42, the one-way locking assembly includes a sealing cylinder 83, the blocking assembly is arranged on the sealing cylinder 83, and the push assembly is arranged on the cutting device 1. The pushing unit is composed of a pushing assembly, an adjusting assembly and a pressing assembly, the pushing assembly is arranged on the first slide 41 and the second slide 42, and the adjusting assembly and the pressing assembly are both arranged on the pushing assembly;

[0050] The first clamping assembly includes a first clamping plate 71, an axle 72, a pulley 73, a cable 74 and a counterweight 75.

One end of the cable 74 is connected to one of the slide seats, and the other end of the cable 74 is connected to the counterweight 75. The cable 74 bypasses the pulley 73. Two blocks are fixed on the cutting device 1. The two blocks block the two slide seats respectively. The second clamping assembly includes a second clamping plate 81, a support plate 82, a sliding plug 84 and a connecting rod 85. The second clamping plate 81 is slidably mounted on the second slide plate 42. The support plate 82 is fixed to the side of the second slide plate 42. The sealing cylinder 83 is fixed to the top surface of the support plate 82. The sliding plug 84 is sealingly slidably arranged inside the sealing cylinder 83. One end of the connecting rod 85 is fixedly connected to the sliding plug 84. The other end of the connecting rod 85 extends to the outside of the sealing cylinder 83 and is fixedly connected to the second clamping plate 81. The sliding plug 84 is connected to the inner surface of the sealing cylinder 83 via a first spring 86.

[0051] like Figures 5 to 7As shown, the one-way locking assembly includes an oil storage tank 91, a mounting tube 92 and a one-way valve 93. The oil storage tank 91 is arranged on the cutting device 1. One end of the mounting tube 92 is connected to the sealing cylinder 83, and the other end is connected to the oil storage tank 91. The one-way valve 93 is installed on the mounting tube 92. The one-way valve 93 restricts the oil from entering the sealing cylinder 83. The blocking assembly includes a fixed cylinder 101, a through port 102, a blocking frame 103, a blocking core 105 and a reflux pipe 107. The fixed cylinder 101 is fixed to one end of the sealing cylinder 83 away from the second clamping plate 81, and the fixed cylinder 101 is connected to the sealing cylinder 83. The through port 102 is opened at one end of the fixed cylinder 101 away from the sealing cylinder 83. The blocking frame 103 is fixed inside the fixed cylinder 101. The blocking frame 103 is provided with an oil hole 104. The blocking core 105 5 is connected to the blocking frame 103 through the second spring 106, the blocking core 105 is arranged opposite to the oil hole 104, and the shape of the blocking core 105 is adapted to the blocking frame 103, one end of the return pipe 107 is connected to the fixed cylinder 101, and the other end is connected to the oil storage tank 91, the communication position of the return pipe 107 and the fixed cylinder 101 is located between the blocking frame 103 and the through port 102, the push assembly includes a mounting frame 111, an outer cylinder 112 and a push rod 113, the mounting frame 111 is fixed on the cutting device 1, the outer cylinder 112 is fixed at one end of the mounting frame 111 away from the cutting device 1, the push rod 113 is movably inserted in the outer cylinder 112, and one end of the push rod 113 extends to the outside of the outer cylinder 112, the outer cylinder 112 and the push rod 113 are connected by a third spring 114, and the push rod 113 is arranged opposite to the through port 102;

[0052] In the present invention, in order to ensure the fixing effect of the first clamping plate 71 and the second clamping plate 81 on the plate, the first slide plate 41 and the second slide plate 42 are both provided with a limiting function for the first clamping plate 71 and the second clamping plate 81. Specifically, the first clamping plate 71 can pull the pull wire 74 when moving, so that the pull wire 74 pulls the counterweight block 75. Under the gravity of the counterweight block 75, the first clamping plate 71 always has a tendency to move in the direction of the avoidance gap 43, which makes the first clamping plate 71 always able to press the plate. For the second clamping plate 81, when the second clamping plate 81 moves, it can drive the connecting rod 85 to move, so that the connecting rod 85 drives the sliding plug 84 to move. When the sliding plug 84 moves, it can extract the oil in the oil storage box 91 through the mounting tube 92, so that the oil is drawn into the interior of the sealing tube 83. Since a one-way valve is installed on the mounting tube 92 93, and the one-way valve 93 limits the oil to only enter the inside of the sealing cylinder 83, but cannot flow out of the sealing cylinder 83, that is, after the oil is drawn into the inside of the sealing cylinder 83, it cannot flow back from the mounting pipe 92 to the oil storage box 91. This design realizes the one-way locking effect of the second clamping plate 81, so that the second clamping plate 81 cannot move in the reverse direction during the process of clamping the plate. Even if the push plate 123 follows the linear slide 122 to reset and separates from the baffle 124 on the second clamping plate 81, the second clamping plate 81 will not move in the reverse direction. The one-way locking of the second clamping plate 81 cooperates with the pressing effect of the first clamping plate 71 to achieve the clamping and fixing of the plate, which enables the first clamping plate 71 and the second clamping plate 81 to smoothly drive the plate to move, and can prevent the plate from shaking when the circular saw blade 2 cuts the plate, thereby ensuring the cutting effect of the device on the plate.

[0053] When the push cylinder 5 drives the first slide plate 41 to move, the second slide plate 42 moves accordingly, and the support plate 82 and the sealing cylinder 83 also move accordingly. When the cutting action of the plate is completed, the push rod 113 will be inserted into the through port 102, and pass through the oil hole 104 to push the plugging core 105. When the push rod 113 does not push the plugging core 105, the plugging core 105 is in a state of blocking the oil hole 104 under the action of the second spring 106. At this time, the oil in the sealing cylinder 83 cannot leak out through the oil hole 104. When the push rod 113 pushes the plugging core 105 to move, the plugging core 105 cannot Then the oil hole 104 is blocked, and the oil in the sealing cylinder 83 can be discharged through the oil hole 104 and flow back to the inside of the oil storage box 91 through the return pipe 107. When the oil flows back, the oil no longer hinders the sliding plug 84 from returning to its original position. At this time, the sliding plug 84 will return to its original position under the elastic force of the first spring 86. When the sliding plug 84 returns to its original position, the connecting rod 85 and the second clamping plate 81 will return to their original position accordingly, thereby automatically releasing the clamping action of the first clamping plate 71 and the second clamping plate 81 on the plate, which makes it easier for the staff to take out the plate from between the first clamping plate 71 and the second clamping plate 81 after cutting.

[0054] like Figure 4 and Fig. 9 As shown, the pushing assembly includes a linear drive module 121, a push plate 123 and a baffle 124, the linear drive module 121 is arranged on the first slide 41 and the second slide 42, the linear drive module 121 is provided with a linear slide 122 for linear movement, the push plate 123 is fixed to the side of the linear slide 122, the baffle 124 is fixed to the top surface of the second clamping plate 81, the push plate 123 is arranged opposite to the baffle 124, and the bottom surface of the push plate 123 is aligned with the first slide 41 and the second slide 42. The top surfaces of the two clamping plates 81 are flush with each other, and the adjustment assembly includes two fixed plates 131, a horizontal plate 132, a sliding frame 133 and a micro switch 134. The two fixed plates 131 are respectively fixed at the two ends of the linear drive module 121, the horizontal plate 132 is fixed between the two fixed plates 131, the sliding frame 133 is slidably sleeved on the horizontal plate 132, and the micro switch 134 is installed on the bottom surface of the sliding frame 133, and the micro switch 134 is arranged opposite to the push plate 123;

[0055] In the initial state, the first clamping plate 71 is located at a position aligned with the avoidance gap 43, and the second clamping plate 81 is located on the end of the second slide plate 42 away from the first slide plate 41. At this time, a plate placement area is formed between the first clamping plate 71 and the second clamping plate 81. During automatic feeding, the plate automatic feeding device 34 places the plate between the first clamping plate 71 and the second clamping plate 81, and then the pushing unit is operated. For the pushing unit, the linear drive module 121 drives the linear slide 122 to move, and the linear slide 122 drives the push plate when it moves. 123 moves, causing the push plate 123 to move toward the direction close to the second clamping plate 81. Since the baffle 124 is arranged opposite to the push plate 123, the push plate 123 will contact the baffle 124 during the movement and push the baffle 124 to move. When the baffle 124 moves, it can drive the second clamping plate 81 to move. During the movement, the second clamping plate 81 will contact the plate and push the plate to move. When the plate contacts the first clamping plate 71, the plate will push the first clamping plate 71 to move, which makes the first clamping plate 71 and the second clamping plate 81 move. The second clamping plate 81 moves synchronously with the plate. Further, when the push plate 123 moves to the position pressing the micro switch 134, the micro switch 134 is pressed and triggered, and a control signal is sent to the linear drive module 121 to make the linear slide 122 move in the opposite direction, and the push plate 123 is also reset. When the push plate 123 is reset, the first clamping plate 71, the second clamping plate 81 and the plate no longer move, and the position of the plate will be fixed. When the plate is fixed, the push cylinder 5 operates and drives the first slide plate 41 to move through the fixed block 6. The first slide 41 and the second slide 42 are connected by two connecting frames 44. Therefore, when the first slide 41 moves, the first clamping plate 71, the second clamping plate 81 and the plate will move and gradually approach the circular saw blade 2. In this process, the circular saw blade 2 rotating at a high speed completes the cutting process of the plate. It is worth noting that an avoidance gap 43 is formed between the first slide 41 and the second slide 42. During the movement of the first slide 41 and the second slide 42, the circular saw blade 2 will pass through the avoidance gap 43, which is convenient for the circular saw blade 2 to cut the plate.

[0056] like Fig.11 As shown, the clamping assembly includes an opening 135, a clamping block 136, an assembly frame 137 and a vertical rod 138, wherein the opening 135 is provided on the top surface of the sliding frame 133, the clamping block 136 is arranged in the opening 135, the assembly frame 137 is fixed on the top surface of the sliding frame 133, and the assembly frame 137 is in a U-shaped structure, the clamping block 136 and the assembly frame 137 are connected by a fourth spring 139, a hole is provided on the assembly frame 137 that is arranged opposite to the opening 135, the vertical rod 138 is slidably arranged in the hole, and the bottom end of the vertical rod 138 is fixedly connected to the clamping block 136;

[0057] For the micro switch 134, the staff can adjust the position of the micro switch 134 by adjusting the position of the sliding frame 133. When the position of the micro switch 134 changes, the movement stroke and the reset time point of the push plate 123 will also change accordingly. Therefore, the staff can adjust the movement stroke of the plate by adjusting the position of the micro switch 134, thereby adjusting the cutting position of the plate for the device. Specifically, when the staff adjusts the position of the sliding frame 133, the vertical rod 138 is first pulled up, so that the vertical rod 138 drives the clamping block 136 to move upward until the clamping block 136 is separated from the cross plate 132. When the clamping block 136 is separated from the cross plate 132, the clamping block 136 no longer provides a clamping effect on the sliding frame 133, which allows the sliding frame 133 to slide freely on the cross plate 132. At this time, the staff can adjust the position of the sliding frame 133 by pulling the sliding frame 133. 3 and the position of the micro switch 134 are adjusted. After the micro switch 134 is adjusted to a suitable position, the staff loosens the vertical rod 138, so that the pressing block 136 moves down and resets under the action of the fourth spring 139 until the pressing block 136 presses the cross plate 132 again. At this time, the pressing action of the pressing block 136 can fix the sliding frame 133, and the position of the micro switch 134 is also fixed. Furthermore, a scale line is provided on the cross plate 132, which is convenient for the staff to accurately control the position of the micro switch 134. Based on the above process, the staff can accurately control the cutting position of the plate in this way. This design replaces the traditional marking method, which is not only convenient to operate, but also has high precision and eliminates the error caused by marking. Especially for large-scale cutting of plates of the same size, this special design undoubtedly improves the processing efficiency of the device for the plate;
