[0012] Preferably, the speed-changing device includes a motor fixedly connected to the mounting frame and a continuously variable transmission. The output shaft of the motor penetrates through the mounting frame and is fixedly connected to the input end of the continuously variable transmission.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figure 1 shown, the oil impregnation machine for ultra-fine synthetic leather provided by the present invention mainly includes an oil immersion tank 2, an oil storage tank 3, a first mounting plate 5 and a second mounting plate 6 arranged on both sides of the oil storage tank 3, and two extrusion rollers 7 capable of rotating in opposite directions are arranged between the first mounting plate 5 and the second mounting plate 6.

[0033] Further, as Figure 2 shown, a guide roller 4 is rotatably connected inside the oil immersion tank 2.

[0034] As can be seen from the above, when specifically performing the oil impregnation of ultra-fine synthetic leather, the ultra-fine synthetic leather is moved into the oil immersion tank 2. After the ultra-fine synthetic leather is immersed in oil in the oil immersion tank 2 for a period of time through the guide roller 4, it moves in the direction of the extrusion rollers 7, and the two extrusion rollers 7 rotate in opposite directions, thereby driving the extrusion rollers 7 to rotate and extrude the excess oil inside the ultra-fine synthetic leather.

[0035] As Figure 3 、 Figure 9 and Figure 10As shown in the figure, a distance adjustment device 400 is installed on the second mounting plate 6. The distance adjustment device 400 includes fixing plates 402 arranged on both sides of the oil storage tank 3 and adjusting plates 403 symmetrically arranged on both sides of the fixing plates 402. Threaded holes 406 are formed in both of the two adjusting plates 403. Grooves are formed in the fixing plates 402, and a knob 404 is rotatably connected in the grooves. Both ends of the knob 404 are fixedly connected with threaded rods 405 that can be screwed into the threaded holes 406. Slideways 401 are fixedly connected to both the first mounting plate 5 and the second mounting plate 6. The two groups of adjusting plates 403 are slidably connected to the slideways 401, and the fixing plates 402 are fixedly connected to the slideways 401. A rotating shaft 106 is rotatably connected between the two groups of adjusting plates 403, and the rotating shaft 106 is fixedly connected to the pressing roller 7.

[0036] As can be seen from the above, when specifically adjusting the distance between the pressing rollers 7, since the fixing plates 402 are fixedly connected to the slideways 401, the two adjusting plates 403 symmetrically arranged on both sides of the fixing plates 402 are slidably connected to the slideways 401. Then, the knob 404 is rotated to drive the threaded rod 405 to rotate inside the threaded hole 406, so that the two adjusting plates 403 can move towards or away from each other, and then drive the two rotating shafts 106 to move towards or away from each other, making the gap between the pressing rollers 7 adjustable to adapt to the pressing steps of ultra-fiber synthetic leather with different thicknesses.

[0037] As Figure 3 、 Figure 6 and Figure 7 As shown in the figure, a reverse driving device 200 is also installed on the second mounting plate 6. The reverse driving device 200 includes a connecting sleeve 204 rotatably penetrating through the second mounting plate 6 and a rotating rod 201 rotatably connected inside the connecting sleeve 204. First driving gears 205 and first straight gears 203 are respectively fixedly connected to both ends of the connecting sleeve 204. Second driving gears 206 and second straight gears 202 are respectively fixedly connected to both ends of the rotating rod 201. Two transmission gears 105 are respectively meshed with the first driving gear 205 and the second driving gear 206. The connecting sleeve 204 rotatably penetrates through the fixing plate 402 on the second mounting plate 6.

[0038] As can be seen from the above, when specifically performing the reverse rotation of the two rotating shafts 106, the first straight gear 203 is fixedly connected to the first driving gear 205 through the connecting sleeve 204, and the second straight gear 202 is fixedly connected to the second driving gear 206 through the rotating rod 201. The first straight gear 203 and the second straight gear 202 rotate in opposite directions, thereby driving the first driving gear 205 and the second driving gear 206 to rotate in opposite directions, and finally driving the first driving gear 205 and the second driving gear 206 to rotate in opposite directions.

[0039] The above-mentioned two preferred drive gears (the first drive gear 205 and the second drive gear 206) include a central roller and a plurality of trapezoidal teeth fixed on the central roller, and the distance between the outer edge of the trapezoidal teeth and the center of the central roller increases successively in the direction close to the extrusion roller 7.

[0040] As Figures 3 - 5 shown, a transmission device 100 is further installed on the second mounting plate 6, and the transmission device 100 includes an electric push rod 101. The movable end of the electric push rod 101 is fixedly connected with a cross bar 102 and a telescopic rod 103. The movable end of the telescopic rod 103 is fixedly connected with an L-shaped rod 104. Both one end of the L-shaped rod 104 and the cross bar 102 are fixedly connected with arc-shaped sliders 108. A plurality of sliding strips are fixedly connected to the rotating shaft 106. A transmission gear 105 is sleeved on the rotating shaft 106. One side of the transmission gear 105 is fixedly connected with a sliding sleeve 107. A sliding groove for sliding connection with the arc-shaped slider 108 is formed in the sliding sleeve 107, and a groove for matching with the sliding strip is formed in the sliding sleeve 107 and the transmission gear 105.

[0041] As can be seen from the above, when specifically executing the sliding of the transmission gear 105, as Figure 3 and Figure 4 shown, when it is necessary to increase the distance between the two extrusion rollers 7, first, the electric push rod 101 contracts to drive the two transmission gears 105 to be separated from the first drive gear 205 and the second drive gear 206 respectively. Then, the distance between the two extrusion rollers 7 is increased through the distance adjusting device 400. After the adjustment is completed, the electric push rod 101 extends, so that the two transmission gears 105 are respectively re-engaged with the first drive gear 205 and the second drive gear 206. After the increase adjustment, the new engagement positions of the first drive gear 205 and the second drive gear 206 with the transmission gear 105 will shift in the direction close to the extrusion roller 7 relative to the initial engagement positions. Based on the same principle as the above increase adjustment, the separation and engagement between the first drive gear 205 and the second drive gear 206 and the transmission gear 105 are realized, and after the reduction adjustment, the new engagement positions of the first drive gear 205 and the second drive gear 206 with the transmission gear 105 will shift in the direction away from the extrusion roller 7 relative to the initial engagement positions.

[0042] The telescopic rod 103 can adapt to the distance between two rotating shafts 106 moving towards or away from each other. Through the cooperation of the grooves formed in the sliding sleeve 107 and the transmission gear 105 with the sliding strips, the transmission gear 105 can slide on the rotating shaft 106, and at the same time, the transmission gear 105 can drive the rotating shaft 106 to rotate.

[0043] As Figure 3 and Figure 8As shown, a speed change device 300 is further installed on the second mounting plate 6, and the speed change device 300 includes a motor 301 fixedly connected to the mounting frame 1 and a stepless speed variator 302. The output shaft of the motor 301 passes through the mounting frame 1 and is fixedly connected to the input end of the stepless speed variator 302. The output end of the stepless speed variator 302 is fixedly connected with a toothed disc 303, and the toothed disc 303 meshes with the first straight gear 203 and the second straight gear 202.

[0044] As can be seen from the above, when specifically adjusting the speed of the extrusion roller 7, through the connection between the output end of the motor 301 and the stepless speed variator 302, the motor 301 can drive the output end of the stepless speed variator 302 to rotate, thereby driving the toothed disc 303 to rotate. The first straight gear 203 and the second straight gear 202 are respectively meshed on both sides of the toothed disc 303, thereby driving the first straight gear 203 and the second straight gear 202 to rotate in opposite directions coaxially, and further driving the first driving gear 205 and the second driving gear 206 to rotate in opposite directions. Specifically, based on the different speed change transmission ratios of the stepless speed variator 302, the rotational driving speeds of the first driving gear 205 and the second driving gear 206 are also different. Based on this, the rotational speeds of the two extrusion rollers 7 change, so as to be applicable to the transmission drive with different oil immersion times.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
