Description

Technical Field

[0001] The utility model relates to the technical field of open mills, in particular to an open mill for producing wear-resistant layers of floors. Background Art

[0002] An open mill is a machine for rubber (plastic) mixing between two rollers. Materials are drawn into the gap between the two oppositely rotating rollers at different linear speeds under the action of friction. The materials passing through the gap between the rollers are subjected to strong shearing and extrusion, causing the temperature of the materials to rise and the plasticity to increase, so as to achieve the purpose of rubber mixing. It is used for operations such as plastic mixing, mixing, sheet pressing, and hot mixing. In the process of using the existing open mill, some materials will fall off, but the fallen materials are relatively scattered, which is not convenient for the staff to pick up and has certain potential safety hazards.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution: an open mill for producing a wear-resistant layer of a floor, including a base 1, a support frame 2 is fixedly installed on the top of the base 1, the support frame 2 is in an inverted "U" shape, and a pressing mechanism for mixing materials is installed on the support frame 2. The pressing mechanism includes a first pressing roller 5 and a second pressing roller 7 rotatably installed in the middle of the support frame 2. The first pressing roller 5 and the second pressing roller 7 are both horizontally installed and parallel to each other.

[0025] The first pressing roller 5 includes a first roller body and a first transmission shaft. The first transmission shaft penetrates through the first roller body along the axis direction of the first roller body, and the first roller body is fixedly installed in cooperation with the first transmission shaft. Both ends of the first transmission shaft are rotatably installed in cooperation with the support frame 2.

[0026] The second pressing roller 7 includes a second roller body and a second transmission shaft. The second transmission shaft penetrates through the second roller body along the axis direction of the second roller body, and the second roller body is fixedly installed in cooperation with the second transmission shaft. Both ends of the second transmission shaft are rotatably installed in cooperation with the support frame 2. A motor 11 is fixedly installed on one side of the support frame 2. The output end of the motor 11 passes through the support frame 2 and is fixedly installed in cooperation with the second transmission shaft. A first transmission component is installed between the second transmission shaft and the first transmission shaft.

[0027] The first transmission component includes a first gear 18 and a second gear 19. The first gear 18 is fixedly sleeved on the end of the second transmission shaft away from the motor 11. The second gear 19 is fixedly sleeved on one end of the first transmission shaft, and the second gear 19 is meshed and connected with the first gear 18.

[0028] A receiving plate 3 is installed below the first pressing roller 5 and the second pressing roller 7. One side of the lower surface of the receiving plate 3 is hingedly installed with a connecting block 4 through a hinge shaft, and the bottom end of the connecting block 4 is fixedly installed in cooperation with the base 1. Symmetrically fixed on the side of the lower surface of the receiving plate 3 away from the connecting block 4 are springs 15. Symmetrically fixed on the upper surface of the base 1 are limiting rods 16. The limiting rods 16 correspond to the springs 15 one by one. The springs 15 are sleeved on the corresponding limiting rods 16, and the limiting rods 16 play a role in limiting the springs 15. The bottom ends of the springs 15 are fixedly installed in cooperation with the base 1.

[0029] A connecting shaft 14 is installed below the material receiving plate 3. Both ends of the connecting shaft 14 are rotatably fitted and installed with the support frame 2. One end of the connecting shaft 14 passes through the support frame 2 and is fixedly sleeved with a second belt pulley 13. One end of the first transmission shaft passes through the support frame 2 and is fixedly sleeved with a first belt pulley 10. A first transmission belt 12 is sleeved on the first belt pulley 10 and the second belt pulley 13.

[0030] A convex block 17 is fixedly sleeved in the middle of the connecting shaft 14. When the convex block 17 rotates, it slides in cooperation with the lower surface of the material receiving plate 3 and drives the material receiving plate 3 to turn upwards. This is conducive to the materials on the material receiving plate 3 gathering on one side of the upper surface of the material receiving plate 3, facilitating the staff to pick them up.

[0031] A pressure plate 8 is installed above the first pressing roller 5 and the second pressing roller 7. The pressure plate 8 is arranged horizontally. Sliding grooves 6 are vertically opened on both sides inside the support frame 2. Both ends of the pressure plate 8 are slidably fitted and installed with the corresponding sliding grooves 6. The sliding grooves 6 can play a guiding role when the pressure plate 8 moves up and down.

[0032] A driving mechanism for driving the pressure plate 8 to move up and down is installed at the top of the support frame 2. The driving mechanism includes an electric push rod 9. The electric push rod 9 is fixedly installed in the middle of the top of the support frame 2. The output end of the electric push rod 9 passes through the support frame 2 and is fixedly fitted and installed with the middle of the pressure plate 8.

[0033] The working principle of the open mill for producing the wear-resistant layer of the floor provided by this embodiment is as follows:

[0034] In the initial state, the bottom surface of the material receiving plate 3 contacts the top end of the limiting rod 16, and the material receiving plate 3 is in an inclined state. The spring 15 is in a natural state.

[0035] When in use, start the motor 11 to drive the second pressing roller 7 to rotate. The second pressing roller 7 drives the first gear 18 to rotate. The rotation of the first gear 18 drives the second gear 19 to rotate. The second gear 19 drives the first pressing roller 5 to rotate. Thus, the rotation directions of the first pressing roller 5 and the second pressing roller 7 are opposite, realizing the mixing of the materials.

[0036] When material falls into the receiving plate 3 below, the first pressing roller 5 rotates while driving the first pulley 10 to rotate. The first pulley 10 drives the second pulley 13 to rotate through the first transmission belt 12, and the second pulley 13 drives the connecting shaft 14 to rotate. The connecting shaft 14 drives the protrusion 17 to rotate. When the protrusion 17 rotates, it slides with the lower surface of the receiving plate 3, thereby driving the receiving plate 3 to flip upward, and the upward flipping of the receiving plate 3 will stretch the spring 15. When the protrusion 17 rotates and disengages from the receiving plate 3, the receiving plate 3 flips downward under the action of the reset force of the spring 15, so that the receiving plate 3 continuously swings up and down, achieving the effect of gathering the material above the receiving plate 3. At the same time, during the downward flipping of the receiving plate 3, the bottom surface of the receiving plate 3 will hit the top of the limit rod 16, so that the receiving plate 3 continuously vibrates, and the material in the receiving plate 3 can be gathered on one side of the receiving plate 3, which is convenient for the staff to collect the materials and reduces the safety hazards when the staff collects the materials. Furthermore, the motor 11 can respectively drive the pressing roller to rotate and drive the receiving plate 3 to continuously swing up and down, thereby reducing the manufacturing cost, simplifying the operation, and improving the work efficiency.

[0037] If the material is stuck, the electric push rod 9 is started, and the output end of the electric push rod 9 pushes the pressing plate 8 downward to move downward, so as to achieve the effect of pressing the material by the pressing plate 8. This prevents the material from being stuck during the mixing process, and at the same time avoids improper operation of the staff and personal injury.

[0038] Embodiment 2

[0039] See also Figures 5-6 The utility model provides a technical solution: an open mill for producing a wear-resistant layer of a floor, based on the first embodiment and different from the first embodiment in that the driving mechanism includes a connecting plate 25 and a connecting rod 23. The connecting plate 25 includes a horizontal plate, a vertical rod is fixedly installed on one side of the bottom surface of the horizontal plate, and a vertical plate is fixedly installed on the other side of the bottom surface of the horizontal plate. The vertical rod of the connecting plate 25 passes through the middle of the top of the support frame 2, and the bottom end of the vertical rod of the connecting plate 25 is fixedly mounted with the press plate 8. A connection frame 24 is fixedly installed at the bottom end of the vertical plate of the connecting plate 25.

[0040] The connecting rod 23 includes a rotating shaft and a connecting plate. The rotating shaft is rotatably mounted on one side of the support frame 2, and one end of the rotating shaft away from the support frame 2 is fixedly mounted with the connecting plate. A boss 26 is fixedly mounted on one side of the connecting plate, and the boss 26 is inserted into the connecting frame 24 and slidably mounted with the connecting frame 24.

[0041] A second transmission assembly is installed between the rotating shaft of the connecting rod 23 and the first transmission shaft of the first pressing roller 5. The second transmission assembly includes a third pulley 20 and a fourth pulley 22. The third pulley 20 is fixedly sleeved at one end of the first transmission shaft, the fourth pulley 22 is fixedly sleeved on the rotating shaft of the connecting rod 23, and a second transmission belt 21 is sleeved on the fourth pulley 22 and the third pulley 20.

[0042] The working principle of the open mill for producing the wear-resistant layer of the floor provided in this embodiment is different from that of the first embodiment in that:

[0043] When the first pressing roller 5 rotates, the first transmission shaft of the first pressing roller 5 drives the third pulley 20 to rotate. The third pulley 20 drives the fourth pulley 22 to rotate through the second transmission belt 21. The fourth pulley 22 drives the rotating shaft of the connecting rod 23 to rotate. The rotation of the rotating shaft of the connecting rod 23 drives the connecting plate to rotate. The rotation of the connecting plate drives the boss 26 to rotate. Since the boss 26 is slidably fitted with the connecting frame 24, when the boss 26 rotates, it drives the entire connecting plate 25 to move up and down reciprocally. The connecting plate 25 drives the pressure plate 8 to move up and down reciprocally, so that the pressure plate 8 presses the material, avoiding the situation of material feeding and jamming. It has a high degree of automation, convenient operation, and improves production efficiency.
