DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] The utility model provides a calendering device for floor production, comprising a base 1. Figure 1 As shown, the base 1 is placed horizontally from side to side, and an inverted U-shaped support frame 2 is welded on the top of the base 1. A four-roller calendering mechanism is installed on the top of the support frame 2, and the four-roller calendering mechanism includes two lower calendering rollers 6 and two upper calendering rollers 12. Four hydraulic cylinders 10 are installed on the top of the support frame 2. The four hydraulic cylinders 10 are distributed in a rectangular array and the output ends are vertically downward and fixedly connected to the top of the support frame 2. The cylinder bodies of the four hydraulic cylinders 10 are fixedly connected to the same rectangular and horizontal connection frame 9, and the four hydraulic cylinders 10 are distributed one by one at the four corners of the connection frame 9. It is used to drive the connection frame 9 to move up and down.

[0025] The two upper calendering rollers 12 correspond to the two lower calendering rollers 6 one by one up and down. The two upper calendering rollers 12 are located at the same vertical height, one on the left and one on the right. The two upper calendering rollers 12 are arranged horizontally front to back and are rotatably assembled in the connecting frame 9. The two lower calendering rollers 6 are arranged horizontally front to back and are rotatably assembled between the two vertical frames of the support frame 2. Each upper calendering roller 12 is located in the same vertical plane as the corresponding lower calendering roller 6. A rectangular through hole is cut on the horizontal frame at the top of the support frame 2, and the tops of the two lower calendering rollers 6 are located in the rectangular through hole and the tops protrude upward from the rectangular through hole, which are used to cooperate with the upper calendering rollers 12 to calender the material.

[0026] like Figure 3 As shown, the rear end of the connecting frame 9 is bolted to the first motor 11, and the output shaft of the first motor 11 is horizontally forward and coaxially fixedly connected to the upper calendering roller 12 located on the left side, so as to drive the upper calendering roller 12 to rotate. The rear end of the vertical frame body of the support frame 2 located on the rear side is bolted to the second motor 15, and the output shaft of the second motor 15 is horizontally forward and coaxially fixedly connected to the lower calendering roller 6 located on the left side, so as to drive the lower calendering roller 6 to rotate.

[0027] like Figure 1As shown, the front ends of the two upper calendering rollers 12 are coaxially fixedly connected to a second pulley 7, and the two second pulleys 7 are driven and sleeved with the same second transmission belt 8, which is used for the synchronous rotation of the two upper calendering rollers 12. The front ends of the two lower calendering rollers 6 are coaxially fixedly connected to a first pulley 4, and the two first pulleys 4 are driven and sleeved with the same first transmission belt 5, which is used for the synchronous rotation of the two lower calendering rollers 6.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, a dynamic screening mechanism is mounted on the support frame 2. The dynamic screening mechanism includes a dynamic drive assembly and a screening plate 13. The screening plate 13 is horizontally arranged left and right and is located directly below the two lower calendering rollers 6. The screening plate 13 is provided with a plurality of screening holes evenly arranged in a linear array and pointing vertically downward. The screening plate 13 is located between the two vertical frames of the support frame 2. The two vertical frames of the support frame 2 are close to each other at their ends, each of which has a horizontally oriented chute 17 cut out. The screening plate 13 is slidably assembled in the chute 17 to ensure the reciprocating sliding of the screening plate 13.

[0029] like Figure 5 As shown, the dynamic drive assembly includes a drive unit, a connecting rod 18, a return frame 19 and a transmission rod 23. The drive unit includes a third motor 16, which is bolted to the rear vertical frame of the support frame 2. The output shaft of the third motor 16, as the output end of the drive unit, passes horizontally forward through the vertical frame of the support frame 2 and is fixedly connected to the connecting rod 18. The connecting rod 18 is arranged along the radial direction of the output shaft of the third motor 16 to ensure that the connecting rod 18 revolves around the central axis of the output shaft of the third motor 16.

[0030] like Figure 4 As shown, the end of the connecting rod 18 away from the output shaft of the third motor 16 is fixedly connected to the transmission rod 23, and the transmission rod 23 is horizontally forward and parallel to the output shaft of the third motor 16. The return frame 19 is placed vertically and fixedly connected to the rear end of the screening plate 13, and the transmission rod 23 is inserted into the return frame 19 and cooperates with the return frame 19 in transmission. A clearance groove is cut on the rear vertical frame of the support frame 2, and the clearance groove is not drawn or marked in the figure. The clearance groove is connected to the slide groove 17 on the vertical frame of the support frame 2. The connecting rod 18 and the return frame 19 are both located in the clearance groove, ensuring that the revolution of the connecting rod 18 is not restricted, and at the same time ensuring that the return frame 19 is not restricted when moving, ensuring that the return frame 19 drives the screening plate 13 to slide back and forth left and right, thereby achieving dynamic screening.

[0031] like Figure 2As shown, two block collection boxes 3 and a powder collection box 14 are placed on the top of the base 1. The powder collection box 14 is located directly below the screening plate 13 and between the two vertical frames of the support frame 2, and is used to receive powdery materials. The two block collection boxes 3 are located between the two vertical frames of the support frame 2 and are located on the left and right sides of the powder collection box 14, and are used to receive large block materials.

[0032] The tops of the two adjacent block collection boxes 3 are inclined plates that are inclined toward the powder collection box 14 , which facilitates receiving bulk materials and ensures that the bulk materials slide smoothly into the block collection box 3 .

[0033] Working principle of embodiment 1:

[0034] In the initial state, the screening plate 13 covers the entire powder collecting box 14, and the connecting rod 18 is in a vertical state.

[0035] When in use, the four hydraulic cylinders 10 are first opened synchronously according to the required calendering parameters, and the four hydraulic cylinders 10 work synchronously. During the extension and retraction of the output ends of the four hydraulic cylinders 10, the cylinder bodies of the four hydraulic cylinders 10 drive the connecting frame 9 to move up and down, and the connecting frame 9 drives the two upper calendering rollers 12 to move up and down synchronously, thereby adjusting the distance between the upper calendering roller 12 and the lower calendering roller 6, with high adaptability and simple structure.

[0036] After the adjustment is completed, the first motor 11 and the second motor 15 are started simultaneously. Then, the output shaft of the first motor 11 drives the connected upper calendering roller 12 to rotate, and the upper calendering roller 12 drives the connected second pulley 7 to rotate, and the second pulley 7 drives another second pulley 7 to rotate through the second transmission belt 8, and the second pulley 7 drives another upper calendering roller 12 to rotate synchronously.

[0037] The output shaft of the second motor 15 drives the connected lower calendering roller 6 to rotate, and the lower calendering roller 6 drives the connected first pulley 4 to rotate, and the first pulley 4 drives another first pulley 4 to rotate through the first transmission belt 5, and this first pulley 4 drives another lower calendering roller 6 to rotate synchronously.

[0038] Then, the material to be calendered is placed between the upper calendering roller 12 and the lower calendering roller 6 for calendering. During the calendering process, the material will fall onto the screening plate 13. At the same time, the third motor 16 is started, and the output shaft of the third motor 16 drives the connecting rod 18 to revolve around the output shaft of the third motor 16, and the connecting rod 18 drives the transmission rod 23 to revolve around the output shaft of the third motor 16. During the revolution of the transmission rod 23, it not only slides up and down and rotates relative to the return frame 19, but also pushes the return frame 19 to reciprocate. During the reciprocating movement, the return frame 19 drives the screening plate 13 to reciprocate along the chute 17 to achieve dynamic screening. During the reciprocating sliding of the screening plate 13, the sieve holes on the screening plate 13 are always in the powder collection box 14 to ensure that the powder material does not spill out.

[0039] At the same time, as the screening plate 13 is sliding back and forth, the powdery material falls through the screen holes into the powdery collection box 14. As the large pieces of material move left and right with the screening plate 13, they fall into the block collection boxes 3 on both sides of the powdery collection box 14 due to inertia, and are finally collected and screened. During the whole process, the screening holes on the screening plate 13 are not blocked by the large pieces of material, which improves the screening effect and the screening efficiency.

[0040] Embodiment 2

[0041] like Figure 6 to Figure 7 The calendering device for floor production shown in the embodiment is different from the embodiment 1 in that the driving unit includes a third pulley 20, a third transmission belt 21 and a fourth pulley 22. The third pulley 20 is coaxially fixedly connected to a lower calendering roller 6, and the lower calendering roller 6 is not connected to the output shaft of the second motor 15. At the same time, the third pulley 20 is located at the rear end of the lower calendering roller 6. The fourth pulley 22 is fixedly sleeved on a rotating shaft, and the rotating shaft passes forward through the vertical frame body located at the rear side of the support frame 2 and is rotatably connected to the frame body. The rotating shaft is fixedly connected to the connecting rod 18, and the connecting rod 18 is arranged along the radial direction of the rotating shaft, and the transmission rod 23 is parallel to the rotating shaft.

[0042] The third pulley 20 and the fourth pulley 22 are both drivingly sleeved in the third transmission belt 21 for transmission.

[0043] Working principle of the second embodiment:

[0044] The difference between this working principle and the working principle of the first embodiment lies in the driving mode of the driving unit. Now only the driving mode of the driving unit is described in detail. The other working processes are the same as the principles of the first embodiment.

[0045] When the two lower calendering rollers 6 rotate, the lower calendering rollers 6 will drive the third pulley 20 to rotate, the third pulley 20 will drive the fourth pulley 22 to rotate through the third transmission belt 21, the fourth pulley 22 will drive the rotating shaft to rotate, the rotating shaft will drive the connecting rod 18 to revolve around the rotating shaft, the connecting rod 18 will drive the transmission rod 23 to revolve around the rotating shaft to complete the drive.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
