DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides two technical solutions:

[0028] Figure 1-Figure 7 The first embodiment is shown: a precision slotting and cutting device for PVC sheet includes a processing table 1, a square slot 2 is provided at the bottom end of the processing table 1, a group of through slots 3 are provided through the inner wall of the square slot 2, the setting of the square slot 2 reduces the thickness of the processing table 1, and facilitates the rotating roller 54 to pass through the through slot 3 to support the sheet, a cutting slot 4 is provided at the top end of the processing table 1, and the setting of the cutting slot 4 facilitates the cutting assembly 8 to perform cutting, and a supporting assembly 5 is provided at the bottom end of the processing table 1 for supporting the sheet; a clamping assembly 6 is provided at the top end of the processing table 1 for fixing the sheet, a material moving assembly 7 is provided below the clamping assembly 6 for driving the sheet to move, and a cutting assembly 8 is provided at the top end of the processing table 1 for cutting the sheet;

[0029] The support assembly 5 includes a support plate 51, which is fixedly connected to the bottom end of the processing table 1. Two first electric push rods 52 are fixedly installed on the inner wall of the support plate 51. The output ends of the two first electric push rods 52 are fixedly installed with connecting blocks 55. A fixed frame 53 is fixedly installed between the opposite sides of the two connecting blocks 55. A group of rotating rollers 54 are rotatably installed on the inner wall of the fixed frame 53. The two first electric push rods 52 are existing technologies, which can drive the fixed frame 53 and the rotating rollers 54 to rise and fall, so that the rotating rollers 54 can support the plate. When the plate moves, the rotating rollers 54 can rotate, thereby reducing the friction of the plate on the processing table 1 and reducing the difficulty of moving the plate.

[0030] The clamping assembly 6 includes a support frame 64, which is fixedly connected to the top of the processing table 1. A second electric push rod 61 is fixedly installed on the top of the support frame 64. The output end of the second electric push rod 61 passes through the top of the support frame 64 and is fixedly installed with a clamping plate 62. A rubber pad 63 is fixedly installed on the bottom end of the clamping plate 62. When the plate is moved to a suitable position for cutting, the second electric push rod 61 can drive the clamping plate 62 and the rubber pad 63 to move downward, applying a certain pressure on the plate to prevent the plate from being offset during the cutting process. At the same time, the rubber pad 63 increases the friction on the plate and prevents the pressure of the clamping plate 62 from being too high to damage the plate.

[0031] Figure 1-Figure 7 A second embodiment is shown, which differs from the first embodiment mainly in that the material moving assembly 7 comprises a third electric push rod 71, which is fixedly mounted on the top of the support frame 64, and the output shaft of the third electric push rod 71 passes through the top of the support frame 64 and is fixedly mounted with a mounting frame 72, and a group of material moving rollers 73 are rotatably mounted on the inner wall of the mounting frame 72. When the plate is lifted up and supported by a plurality of rotating rollers 54, the third electric push rod 71 is turned on, and the third electric push rod 71 drives the mounting frame 72 and a group of material moving rollers 73 to move downward until the material moving rollers 73 contact the plate and apply a certain pressure to the plate, and the outer walls of a group of material moving rollers 73 pass through the inner wall of the mounting frame 72 and extend to the outside, a group of Both ends of the outer wall of the material moving roller 73 are connected by a sprocket chain group 74. An L-shaped mounting plate 75 is fixedly installed on one side of the outer wall of the mounting frame 72. A first motor 76 is fixedly installed on the outer wall of the L-shaped mounting plate 75. The output shaft of the first motor 76 passes through the outer wall of the L-shaped mounting plate 75 and extends to the other side to be fixedly connected to one end of the outer wall of one of the material moving rollers 73. Turning on the first motor 76 allows the first motor 76 to cooperate with the sprocket chain group 74, so that multiple material moving rollers 73 can rotate. When rotating, the material moving roller 73 can drive the plate on the rotating roller 54 to move toward the cutting assembly 8 for cutting. At the same time, when encountering some longer plates, the material moving assembly 7 can continuously drive the plate to move.

[0032] The cutting assembly 8 includes two connecting rods 81, both of which are fixedly connected to the processing table 1. Electric slide rails 82 are fixedly installed on the top of the two connecting rods 81. A moving block 83 is provided at the output end of the electric slide rail 82. The electric slide rail 82 is a prior art and can drive the moving block 83 to move inside it.

[0033] A protective shell 84 is fixedly installed on the outer wall of the moving block 83, and a second motor 85 is fixedly installed on the inner wall of the protective shell 84. The output shaft of the second motor 85 passes through the inner wall of the protective shell 84 and is fixedly installed with a cutting wheel 86. The second motor 85 drives the cutting wheel 86 to rotate at high speed, and then the electric slide rail 82 is turned on. The electric slide rail 82 drives the moving block 83 to move, and the moving block 83 can drive the cutting wheel 86 to move in the cutting groove 4, thereby completing the cutting of the plate.

[0034] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0035] During operation, when it is necessary to cut the plate, the plate is first placed on the processing table 1. When it is necessary to move the plate on the processing table 1 and cut the plate multiple times, the two first electric push rods 52 can be turned on at the same time. The two first electric push rods 52 drive the fixed frame 53 and the rotating rollers 54 to rise, so that a group of rotating rollers 54 pass through the through slot 3 to lift the plate on the processing table 1. At this time, the plate on the processing table 1 contacts with multiple rotating rollers 54, thereby reducing the friction of the plate on the processing table 1 and reducing the difficulty of moving the plate. When the plate is lifted and supported by multiple rotating rollers 54, the third electric push rod 71 is turned on, and the third electric push rod 71 drives the mounting frame 72 and a group of material moving rollers 73 to move downward until the material moving rollers 73 contact the plate and apply a certain pressure to the plate. At this time, the first motor 76 is turned on, so that the first motor 76 cooperates with the sprocket chain group 74, so that the multiple material moving rollers 73 rotate, and the material moving rollers 73 can drive the rotating rollers 73 when rotating. The plate on the movable roller 54 moves toward the cutting assembly 8 for cutting. At the same time, when encountering some longer plates, the material moving assembly 7 can continuously drive the plate to move, which is convenient for moving the plate. When the plate moves to the position where cutting is required, the plate is cut at this time, and the two first electric push rods 52 are turned on again. The two first electric push rods 52 descend, so that the rotating roller 54 descends to the bottom of the through groove 3. At this time, the plate contacts the surface of the processing table 1, and then the second electric push rod 61 is turned on. The second electric push rod 61 drives the clamping plate 62 and the rubber pad 63 to move downward, and applies a certain pressure to the plate to prevent the plate from shifting during the cutting process. When the plate is fixed, the second motor 85 is turned on, and the second motor 85 drives the cutting wheel 86 to rotate at a high speed, and then the electric slide rail 82 is turned on. The electric slide rail 82 drives the moving block 83 to move, and the moving block 83 can drive the cutting wheel 86 to move in the cutting groove 4, thereby completing the cutting of the plate.
