DETAILED DESCRIPTION

[0021] 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.

[0022] like Figures 1 to 5 As shown, the utility model provides a PVC plastic floor shearing device with neat incisions, including a fixed base 1, the fixed base 1 is a square structure, a gantry plate 4 is fixedly connected to the middle of the top of the fixed base 1, a mounting seat 6 is provided in the inner cavity of the gantry plate 4, the mounting seat 6 is made of metal, a cutting knife 7 is fixedly installed at the bottom of the mounting seat 6 by bolts, the bottom end and both sides of the cutting knife 7 are cutting surfaces, an auxiliary cutting component is provided below the inner cavity of the gantry plate 4, refer to the attached Figure 1 and attached Figure 4 The auxiliary cutting assembly includes a positioning frame 5 arranged below the inner cavity of the gantry plate 4. The positioning frame 5 is a hollow plate, and the hollow diameter is twice as large as the maximum diameter of the mounting seat 6, ensuring that the mounting seat 6 can pass through the positioning frame 5 normally. Two guide rollers 13 are symmetrically installed inside the positioning frame 5. Two strip positioning blocks 14 are symmetrically fixedly connected to the lower surface of the positioning frame 5. The strip positioning blocks 14 are made of hard material and the lower surface is frosted. Both ends of the two guide rollers 13 are connected to the positioning frame 5 through bearings, so that the two guide rollers 13 can rotate in the positioning frame 5, and the outer wall of the guide roller 13 is provided with a soft rubber material. , has a certain elasticity, and the straight-line distance between the guide roller 13 and the fixed base 1 is slightly larger than the straight-line distance between the strip positioning blocks 14, so that when the positioning frame 5 moves toward the fixed base 1, the guide roller 13 first contacts the PVC plastic floor on the fixed base 1. At this time, the PVC plastic board can be smoothed by the downward rolling of the guide roller 13. This method can ensure the smoothness of the cut surface of the PVC plastic floor after cutting. Then the positioning frame 5 continues to press down until the two strip positioning blocks 14 realize the downward pressing and fixing of the two sides of the cutting position of the PVC plastic floor. At this time, the two strip positioning blocks 14 are used to fix the PVC plastic floor.

[0023] An input conveyor belt 2 is installed on one side of the fixed base 1, and an output conveyor belt 3 is installed on the other side of the fixed base 1. Figure 1 and attached Figure 5A cutting groove 15 is provided in the middle of the fixed base 1 below the cutting knife 7. The inner diameter of the cutting groove 15 is two to three times larger than the thickness of the cutting knife 7. The PVC plastic floor is smoothly put in from the position of the input conveyor belt 2. Then, the PVC plastic floor is conveyed to the top of the cutting groove 15 under the operation of the input conveyor belt 2. When the cutting of the PVC plastic floor is completed, the PVC plastic floor after cutting can be conveyed out under the operation of the output conveyor belt 3.

[0024] Reference Figure 1 and attached Figure 3 A strip groove 8 is provided at the top of the gantry plate 4, and a connecting block 9 is provided inside the strip groove 8 for sliding. The connecting block 9 can be limited to move horizontally in the strip groove 8. A first electric push rod 10 is fixedly installed on the lower surface of the connecting block 9. The first electric push rod 10 is electrically connected to the external power supply through an external power line. The output end of the first electric push rod 10 is fixedly connected to the upper surface of the mounting seat 6. The operation of the first electric push rod 10 can ultimately realize the up and down movement of the cutting knife 7. A screw rod 11 is installed inside the strip groove 8. The screw rod 11 can rotate in the strip groove 8. The connecting block 9 is threadedly sleeved on the outside of the screw rod 11. Through the threaded sleeve connection between the connecting block 9 and the screw rod 11, the connecting block 9 is realized when the screw rod 11 rotates. The left and right movement of the strip groove 8 finally realizes the left and right movement of the cutting knife 7. The cross-cutting of the PVC plastic floor by the cutting knife 7 and the small up and down movement of the first electric push rod 10 can avoid the situation that when the cutting knife 7 directly cuts the PVC plastic floor vertically, the PVC plastic floor is stretched toward the cutting force position, or even worse, the floor will break at the cutting position, thereby affecting the cutting effect of the PVC plastic floor. A driving motor 12 is fixedly installed on the top of one side of the gantry plate 4. The driving motor 12 is electrically connected to an external power supply through an external power cord. The output end of the driving motor 12 is fixedly connected to one end of the screw rod 11, and the other end of the screw rod 11 is connected to the inner wall of the strip groove 8 through a bearing.

[0025] The bottom ends of both ends of the gantry plate 4 are provided with mounting grooves 16, and the top ends of the inner cavities of the two mounting grooves 16 are fixedly installed with second electric push rods 17, and the second electric push rods 17 are electrically connected to the external power supply through an external power line, and the two second electric push rods 17 have the same model and power, and the output ends of the two second electric push rods 17 are fixedly connected with fixed blocks 18, and the two fixed blocks 18 are symmetrically fixedly connected to the two sides of the positioning frame 5. By utilizing the synchronous operation of the two second electric push rods 17, the positioning frame 5 can be moved up and down, thereby meeting the clamping and fixation of PVC plastic floors of various thicknesses.

[0026] The working principle and process of this utility model are as follows:

[0027] When using, refer to the attached Figure 1The driving motor 12 drives the screw rod 11 to rotate, and the rotation of the screw rod 11 drives the connecting block 9 to move in the strip groove 8. The movement of the connecting block 9 drives the first electric push rod 10 and the cutting knife 7 to move until the cutting knife 7 is moved to the sidemost position.

[0028] When the PVC plastic floor to be processed is placed stably on the input conveyor belt 2, the input conveyor belt 2 can convey the PVC plastic floor to the fixed base 1, and one side of the PVC plastic floor moves to the output conveyor belt 3, and the force is transmitted to the output conveyor belt 3 to run toward the output end.

[0029] The two second electric push rods 17 are operated synchronously. At this time, the two fixed blocks 18 are forced to move downward synchronously. The movement of the two fixed blocks 18 drives the positioning frame 5 downward. When the positioning frame 5 moves downward to a certain position, the two guide rollers 13 first contact the PVC plastic floor. At this time, the guide rollers 13 are used to press and roll the PVC plastic floor to smooth the PVC plastic board. When the PVC plastic floor moves to a suitable cutting position, the second electric push rod 17 continues to operate until the two strip positioning blocks 14 press and fix the PVC plastic floor. The second electric push rod 17 is stopped. At this time, the PVC plastic floor is fixed on the fixed base 1.

[0030] The first electric push rod 10 is operated to drive the mounting seat 6 and the cutting knife 7 to move downward synchronously until the cutting knife 7 cuts the side of the PVC plastic floor. At this time, the driving motor 12 is operated in the synchronous direction to drive the cutting knife 7 to move toward the other side of the PVC plastic floor. At the same time, the first electric push rod 10 is controlled to extend and retract slightly, and the cutting knife 7 is used to perform horizontal cutting and vertical cutting of the PVC plastic floor until the cutting work of the PVC plastic floor is completed. This method ensures the neatness of the cutting surface of the PVC plastic floor.

[0031] In addition, since conveyor belts are common and mature products for transporting goods, in order to avoid position displacement of the goods on the conveyor belt during the transportation process, sensor devices such as contact sensors are usually added to the equipment to monitor the product position in real time. Once position displacement is found, it is corrected in time to ensure normal processing of the product. Since the technology is relatively mature and common, the relevant structure is not added to the drawings of this embodiment, so it will not be repeated here.
