Abstract
Description
Technical Field
[0001] The utility model relates to a cutting device for SPC stone plastic floor, belonging to the field of auxiliary equipment for cutting stone plastic floor. Background Art
[0002] The cutting of stone plastic floor is mainly carried out by a cutting knife or a wire saw. Since the stone plastic floor is adhesively bonded by multiple layers of organic materials, and because the interval time from manufacturing completion is short, the adhesive cannot be fully cured. During the cutting process of the cutting knife and the wire saw, not only will the high temperature affect the bonding effect of the stone plastic floor, but also the radial cutting force during the cutting process will drive the relative sliding between the various layers of the stone plastic floor, thereby affecting the bonding effect and stacking quality of the stone plastic floor at the cutting position. More seriously, the entire layer will be driven to wrinkle and shift due to the migration of the end layer, affecting the overall quality of the floor. Content of the Utility Model

[0028] The lower clamping plate 2 is fixed to the machine table through the support base 1.
[0029] As Figure 1, a clamping mechanism, the clamping mechanism includes rotating arms symmetrically arranged at the two transverse ends of the lower clamping plate 2. A sliding seat 30 is slidably connected to the middle of the rotating arm. The sliding seats 30 of the two groups of rotating arms are rotatably connected to the two transverse ends of the upper clamping plate 7. A pushing seat 20 is arranged above the corresponding sliding seat 30 of the rotating arm. The pushing seat 20 and the sliding seat 30 are elastically connected by a support spring 21 sleeved on a rotating rod 15.
[0030] As Figure 1 , a transverse pushing mechanism, the transverse pushing mechanism includes a transverse pushing plate 16. The other ends of the two groups of rotating arms are rotatably connected to the two transverse ends of the transverse pushing plate 16. A driving plate is slidably connected between the pushing seats 20. A transverse pusher with a driving direction parallel to the plane of the driving plate is arranged between the driving plate and the transverse pushing plate 16; the rotating arm includes two groups of rotating rods 15 arranged at the two longitudinal ends of the lower clamping plate 2. A main rotating shaft 17 is fixedly penetrated and fixed on the lower clamping plate 2. The end of the rotating rod 15 is rotatably connected to the main rotating shaft 17; a secondary rotating shaft 18 is fixedly penetrated and fixed at the two longitudinal ends of the transverse pushing plate 16. The other end of the rotating rod 15 is rotatably connected to the secondary rotating shaft 18; a middle rotating shaft 29 is fixedly penetrated and fixed at the two transverse ends of the upper clamping plate 7. The two ends of the middle rotating shaft 29 are rotatably connected to the sliding seat 30. The sliding seat 30 is slidably sleeved on the rotating rod 15; the driving plate includes two groups of driving rods 14. The end of the driving rod 14 is connected with a pushing seat 20 through a universal ball hinge structure 19. The pushing seat 20 is slidably sleeved on the rotating rod 15.
[0031] As Figure 1 , the transverse pusher includes a rotating driving seat 22 fixed on the transverse pushing plate 16. A transverse driving motor is arranged on the rotating driving seat 22. Driving discs 23 are fixed at both ends of the motor shaft of the transverse driving motor. A driving column 24 is fixedly connected to the driving disc 23; the transverse pusher further includes a pushing block 25 fixed on the two driving rods 14. A pushing groove 26 with an axis perpendicular to the plane of the driving plate is arranged on the pushing block 25. The aforementioned driving column 24 is in sliding contact with the pushing groove 26.
[0032] As Figure 1 , a longitudinal pusher with a driving direction perpendicular to the plane of the driving plate between the driving plate and the transverse pushing plate 16. A transverse sliding sleeve 27 is slidably connected to the driving rod 14. The longitudinal pusher includes two pushing oil cylinders 28 symmetrically arranged at the two longitudinal ends of the transverse pushing plate 16. One end of the pushing oil cylinder 28 is rotatably connected to the longitudinal end of the driving plate. The other end of the pushing oil cylinder 28 is rotatably connected to the side wall of the transverse sliding sleeve 27.
[0033] As Figure 1, the stone plastic floor mainly includes a resin layer located at the top. There is a decorative layer below the resin layer, and a stone plastic layer below the decorative layer. A support layer made of foam or rubber can be optionally attached below the stone plastic layer. This device is mainly designed for processing stone plastic floors without an attached support layer. Since the support layer is relatively soft and easy to cut, there is no need to consider the extrusion stress during cutting. During use, the stone plastic floor is placed on the lower clamping plate 2. Through the negative pressure of the lower negative pressure chamber 3, the bottom of the stone plastic floor, that is, the stone plastic layer, is adsorbed onto the lower clamping plate 2. Subsequently, through the push oil cylinder 28, the driving rod 14 is pressed down. The driving rod 14 drives the push seat 20 to move relative to the rotating rod 15. Then, the push seat 20 squeezes the sliding seat 30 through the support spring 21. The sliding seat 30 drives the lower clamping plate 2 to contact the resin layer of the stone plastic floor, and adsorbs and fixes the resin layer through the upper negative pressure chamber 8. Subsequently, cutting is carried out. During the cutting process, the driving motor drives the driving disk 23 to drive the driving column 24 to move in the direction opposite to the rotation direction of the cutting knife, thereby driving the push block 25 to move. The push block 25 synchronously drives the driving rod 14 to move relative to the horizontal push plate 16 in a direction parallel to the ground, causing the upper clamping plate 7 to move relative to the lower clamping plate 2 under the drive of the rotating rod 15. During the movement, the resin layer will be subjected to a traction force in the direction of the cutting direction. At the same time, due to the huge friction force brought by the adhesive between the resin layer, the decorative layer, and the stone plastic layer, slight deformations in the direction opposite to the cutting direction will occur between the layers, thereby preventing deviation under the action of the overall cutting force.
[0034] Inspired by the above ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
