[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a calender for artificial leather, which has the following beneficial effects:

[0018] 1. The artificial leather calender can indirectly drive the roller and the face gear located above to move upward by controlling the counterclockwise rotation of the handle. Because the cylindrical gear is longer, when the roller and the face gear located above move upward, the teeth of the upper face gear and the teeth of the cylindrical gear are always in a meshing state until they move upward to a specified position, thereby increasing the gap between the inner sides of the rollers, and vice versa, reducing the gap between the inner sides of the rollers. This process does not require the installation of gears of different sizes, and can ensure that the face gear and the cylindrical gear are always in a meshing state. The operation steps are relatively few, saving time and effort, and facilitating the staff to quickly adjust the gap between the rollers.

[0019] 2. The artificial leather calender can effectively limit the moving transmission frame through the setting of the fixed rod, thereby ensuring the stability of the transmission frame when it moves up and down;

[0020] The setting of the limiting ring can effectively limit the rotating shaft in rotation, effectively preventing the rotating shaft and the roller from moving left and right during rotation, and ensuring the stability of the rotating shaft and the roller during rotation;

[0021] The connection area between the fixing frame and the bottom plate is increased by the reinforcement piece, thereby improving the stability of the fixing frame when in use;

[0022] Due to the characteristics of the rubber pad, it can effectively absorb the vibration force generated by the running drive motor, achieve the function of shock absorption, and prevent the loosening of parts on the drive motor caused by excessive vibration for a long time.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-4The present invention provides a technical solution: a calender for artificial leather, comprising a bottom plate 1, a fixed frame 2 is fixedly connected to the upper surface of the bottom plate 1, a sliding groove 3 is opened on the top of the outer side of the fixed frame 2, a transmission frame 4 is slidably connected inside the sliding groove 3, a turntable 5 is rotatably connected inside the transmission frame 4, a transmission screw 6 is fixedly connected to the upper surface of the turntable 5, the transmission screw 6 penetrates the upper surface of the transmission frame 4, the transmission screw 6 penetrates the upper surface of the fixed frame 2, the transmission screw 6 is threadedly connected to the fixed frame 2, and the top of the transmission screw 6 A hand-cranked wheel 7 is fixedly connected, and a handle 8 is fixedly connected to the upper surface of the hand-cranked wheel 7. A rotating shaft 9 is movably penetrated through the bottom of the outer side surface of the fixed frame 2 and the outer side surface of the transmission frame 4. Rollers 10 are fixedly sleeved on the outer surfaces of the two groups of rotating shafts 9. Surface gears 11 are fixedly sleeved on the rightmost sides of the outer surfaces of the two groups of rotating shafts 9. A mounting frame 12 is fixedly connected to the right side of the upper surface of the bottom plate 1. A transmission shaft 13 is movably inserted into the inner wall of the mounting frame 12. A cylindrical gear 14 is fixedly sleeved on the top of the outer surface of the transmission shaft 13. Both groups of surface gears 11 are meshed with the cylindrical gear 14.

[0030] In the present invention, in order to ensure the stability of the transmission frame 4 when it slides along the inside of the sliding groove 3, a fixing rod 15 is fixedly connected to the inner wall of the sliding groove 3, and the transmission frame 4 is movably connected to the fixing rod 15. Due to the setting of the fixing rod 15, the transmission frame 4 can move upward or downward along the outer surface of the fixing rod 15 inside the sliding groove 3, which can effectively limit the moving transmission frame 4 and ensure the stability of the transmission frame 4 when it slides along the inside of the sliding groove 3.

[0031] In the present invention, in order to ensure the stability of the two groups of rotating shafts 9 when they are in use, limiting rings 16 are fixedly sleeved on the outer sides of the outer surfaces of the two groups of rotating shafts 9. The inner sides of the two groups of limiting rings 16 located on the upper side are in active contact with the outer sides of the transmission frame 4, and the inner sides of the two groups of limiting rings 16 located on the lower side are in active contact with the outer sides of the fixed frame 2. Due to the setting of the limiting rings 16, the rotating shafts 9 in rotation can be effectively limited to prevent the rotating shafts 9 from moving left and right during rotation, thereby ensuring the stability of the two groups of rotating shafts 9 when they are in use.

[0032] In the present invention, in order to improve the stability of the connection between the fixed frame 2 and the base plate 1, a reinforcement member 17 is fixed to the bottom of the inner wall of the fixed frame 2, and the lower surface of the reinforcement member 17 is fixed to the upper surface of the base plate 1. The reinforcement member 17 increases the connection area between the fixed frame 2 and the base plate 1, and improves the stability of the connection between the fixed frame 2 and the base plate 1.

[0033] In the present invention, in order to provide driving force for the two sets of rotating shafts 9 and rollers 10, a pad 18 is fixedly connected to the left side of the upper surface of the base plate 1, and a driving motor 19 is arranged directly above the pad 18. The output end of the driving motor 19 is fixedly connected to the left end of the rotating shaft 9 at the bottom. The driving motor 19 can indirectly drive the rotating shaft 9 and the roller 10 to rotate, thereby providing driving force for the two sets of rotating shafts 9 and the roller 10.

[0034] In the present invention, in order to realize the function of shock absorbing the drive motor 19, a rubber pad 20 is fixedly connected to the upper surface of the cushion block 18, and the lower surface of the drive motor 19 is fixedly connected to the upper surface of the rubber pad 20. Due to the characteristics of the rubber pad 20, the rubber pad 20 can effectively absorb most of the vibration force generated by the drive motor 19 during operation, thereby realizing the function of shock absorbing the drive motor 19.

[0035] In the present invention, in order to prevent the outer side surfaces of the two groups of rollers 10 from rubbing against the inner wall of the fixed frame 2, a gap is left between the outer side surfaces of the two groups of rollers 10 and the inner wall of the fixed frame 2. The size of the gap is set to two millimeters, which prevents the outer side surfaces of the two groups of rollers 10 from being tightly attached to the inner wall of the fixed frame 2 and prevents the outer side surfaces of the two groups of rollers 10 from rubbing against the inner wall of the fixed frame 2.

[0036] In the present invention, in order to facilitate the staff to control the handle 8 to rotate the hand-cranked wheel 7, an anti-slip layer is provided on the outer surface of the handle 8. The material of the anti-slip layer is set to rubber. The anti-slip layer made of rubber material can increase the friction between the palm of the staff and the handle 8 to prevent slipping, thereby facilitating the staff to control the handle 8 to rotate the hand-cranked wheel 7.

[0037] In the present invention, in order to facilitate the rotation of the turntable 5 along the inside of the transmission frame 4, a rotation groove is opened inside the transmission frame 4, and the inner diameter of the rotation groove is larger than one tenth of the outer diameter of the turntable 5. Because the inner diameter of the rotation groove is slightly larger than the outer diameter of the turntable 5, the contact area between the turntable 5 and the inner wall of the transmission frame 4 is reduced, the friction force is reduced, and the turntable 5 is convenient to rotate along the inside of the transmission frame 4.

[0038] When in use, firstly, the spacing between the inner sides of the two groups of rollers 10 needs to be adjusted according to work requirements. The staff holds the handle 8 to drive the hand wheel 7, the transmission screw 6 and the turntable 5 to rotate counterclockwise. At the same time, the transmission screw 6 and the turntable 5 rotate along the inside of the fixed frame 2 and the transmission frame 4 respectively. Due to the characteristics of the threaded connection between the transmission screw 6 and the fixed frame 2, as the turntable 5 rotates along the inside of the transmission frame 4, the transmission frame 4 can be driven to move upward at the same time. The transmission frame 4 moves along the outer surface of the fixed rod 15 in the inner part of the sliding groove 3. The upper part moves upward, and at the same time, the transmission frame 4 drives the upper rotating shaft 9, roller 10, face gear 11, and limit ring 16 to move upward. Because the cylindrical gear 14 is long, when the upper face gear 11 moves upward, its teeth will always be in meshing state with the teeth of the cylindrical gear 14 until it moves to the specified position, so that the distance between the inner sides of the two groups of rollers 10 reaches the specified requirement, and then the rotation of the handle 8 is stopped. At this point, the distance between the inner sides of the two groups of rollers 10 is enlarged, and vice versa, the distance between the inner sides of the two groups of rollers 10 can be reduced;

[0039] Then, when the artificial leather is calendered, the staff starts the driving motor 19, with the left side as the viewing direction. Therefore, the output end of the driving motor 19 drives the bottom shaft 9, the roller 10, and the face gear 11 to rotate clockwise. Because of the characteristics of the gears, the face gear 11 at the bottom drives the cylindrical gear 14 to rotate counterclockwise, and the cylindrical gear 14 drives the outer end of the transmission shaft 13 to rotate along the inside of the mounting frame 12. At the same time, because of the characteristics of the gears, the cylindrical gear 14 drives the upper face gear 11, the shaft 9, and the roller 10 to rotate counterclockwise. At the same time, the upper shaft 9 rotates along the transmission frame 12. The interior of the movable frame 4 rotates, causing the two groups of rollers 10 to start rotating in opposite directions. Subsequently, the staff extends one end of the artificial leather from the rear side into the inner side of the two groups of rollers 10, causing the rollers 10 to calender the artificial leather, so that the calendered artificial leather comes out from the front side until the calendering of the artificial leather is completed. At the same time, the two groups of rotating shafts 9 can simultaneously drive the four groups of limiting rings 16 to rotate, so that the inner side surfaces of the two groups of limiting rings 16 located above and the inner side surfaces of the limiting rings 16 located below are respectively rotated against the outer side surfaces of the transmission frame 4 and the outer side surfaces of the fixed frame 2, which can effectively limit the rotating shaft 9 to prevent left and right movement.

[0040] The artificial leather calender can indirectly drive the roller 10 and the face gear 11 located above to move upward by controlling the handle 8 to rotate counterclockwise. Because the cylindrical gear 14 is longer, when the roller 10 and the face gear 11 located above move upward, the teeth of the upper face gear 11 and the teeth of the cylindrical gear 14 are always in a meshing state until they move upward to a specified position, thereby increasing the gap between the inner sides of the rollers 10, and vice versa, reducing the gap between the inner sides of the rollers 10. This process does not require the installation of gears of different sizes, and can ensure that the face gear 11 and the cylindrical gear 14 are always in a meshing state. The operation steps are relatively few, saving time and effort, and facilitating the staff to quickly adjust the gap between the rollers 10.

[0041] The artificial leather calender can effectively limit the moving transmission frame 4 by setting the fixed rod 15, thereby ensuring the stability of the transmission frame 4 when it moves up and down;

[0042] By setting the limiting ring 16, the rotating shaft 9 can be effectively limited, which effectively prevents the rotating shaft 9 and the roller 10 from moving left and right during rotation, thereby ensuring the stability of the rotating shaft 9 and the roller 10 during rotation;

[0043] The reinforcement member 17 increases the connection area between the fixing frame 2 and the bottom plate 1, thereby improving the stability of the fixing frame 2 when in use;

[0044] Due to the characteristics of the rubber pad 20, the vibration force generated by the running drive motor 19 can be effectively absorbed to achieve the function of shock absorption, thereby preventing the parts on the drive motor 19 from loosening due to excessive vibration force for a long time.

[0045] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0046] The sizes and shapes of all components in this structure are not specifically limited here and need to be produced according to actual conditions.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
