Several third reinforcing plates 17 are provided between the lower connecting plate 15 and the base 1, and are connected by the upper connecting plate 14 and the lower connecting plate 15, thereby separating the side plate 2 from the base 1, so as to clean or tidy the water tank 4 of the base 1. After long-term use, dirt that is difficult to be directly discharged may be generated in the water tank 4. The top of each side plate 2 is connected to the end of the top plate 3. A hydraulic cylinder 5 is provided on the upper surface of the top plate 3. A support roller 6 is provided at the lower part between the two side plates 2. A reduction motor 18 is provided on the outer side of any side plate 2. The output shaft of the reduction motor 18 is connected to the corresponding end of the support roller 6. The reduction motor 18 drives the support roller 6, thereby pulling the leather. The upper surface of the base 1 at both ends of the water tank 4 is provided with upright plates 7. Between the two side plates 2 and on both sides of the support roller 6, a feeding plate 8 and a discharging plate 9 are provided. The top of one upright plate 7 is supported on the lower surface of the feeding plate 8, and the top of the other upright plate 7 is supported on the lower surface of the discharging plate 9. The upper surfaces of the feed tray 8 and the discharge tray 9 near the support roller 6 are both inclined. The ends of the feed tray 8 and the discharge tray 9 away from the support roller 6 extend to the outer end of the side plate 2. The two sides of the feed tray 8 and the discharge tray 9 located at the outer end of the side plate 2 are connected to the side edge of the side plate 2. Support plates 10 are provided on both sides of the side plate 2. The two sides of the feed tray 8 and the discharge tray 9 located at the outer end of the side plate 2 are supported on the upper surface of the support plates 10. Support feet 20 are provided on the lower surface of the base 1 to achieve overall lifting and support.

[0026] A pressure roller 12 is provided at the lower end of the lifting frame 11. The piston rod of the hydraulic cylinder 5 passes through the top plate 3 and is connected to the top of the lifting frame 11. The pressure roller 12 is movably positioned above the support roller 6 and cooperates with the support roller 6.

[0027] like Figure 4As shown, the lifting frame 11 includes a horizontal plate 1101, side plates 1102, a first reinforcing plate 1103, and guide rods 1104. Side plates 1102 are respectively provided at both ends of the horizontal plate 1101. The pressure roller 12 is rotatably connected to the side plates 1102 at both ends. First reinforcing plates 1103 are provided at both ends of the horizontal plate 1101 and at the connection points with the side plates 1102. A plurality of guide rods 1104 are provided on the upper surface of the horizontal plate 1101, and a plurality of guide sleeves 13 are provided on the top plate 3. The guide rods 1104 and guide sleeves 13 correspond one-to-one and provide guiding cooperation. The horizontal plate 1101... The first reinforcing plate 1103 is fastened to the side plate 1101 and the side plate 1102 by bolts. (Here, both the side plate 1101 and the side plate 1102 are provided with countersunk holes to avoid the bolt heads protruding and making it impossible to install inside the equipment.) This enables the installation of the pressure roller 12. The pressure roller 12 is rotatably connected to the side plate 1102 by bearings to ensure the smoothness of the pressure roller 12 when rotating. The top plate 3 is cooperated with by the guide rod 1104 and the guide sleeve 13 to ensure the stability of the lifting frame 11 when it is raised and lowered.

[0028] Installation method and operating principle: Install the pressure roller 12 between the two side plates 1102 of the lifting frame 11. Then connect the guide rod 1104 to the top of the crossbar. Pass the guide rod 1104 through the guide sleeve 13 of the top plate 3. Then install the hydraulic cylinder 5 on the upper surface of the top plate 3 and connect the piston rod of the hydraulic cylinder 5 to the top plate 3. Next, install the side plates 2 at both ends of the top plate 3. During the process, connect the two ends of the support roller 6 to the side plates 2 through bearings. Install the reduction motor 18 on the outer side of one of the side plates 2. At this time, the output shaft of the reduction motor 18 is exactly engaged with one end of the support roller 6 through a key. Support plates 10 are provided on both sides of the side plate 2. Then insert the feed plate 8 and the discharge plate 9 between the two side plates 2 respectively, and fasten the feed plate 8 and the discharge plate 9 to the side plates 2 with bolts on both sides. The upper part is hoisted above the base 1 by a crane and then slowly lowered so that the side plate 2 is supported on the upper surface of the base 1. At this time, the vertical plates 7 extending from both sides of the base 1 to the water receiving tank 4 are inserted between the two side plates 2, and the feed plate 8 and the discharge plate 9 are supported on the vertical plates 7 on both sides respectively. The feed plate 8 and the discharge plate 9 on both sides of the outer end of the side plate 2 are supported on the support plate 10. The feed plate 8 and the discharge plate 9 on both sides of the outer end of the side plate 2 can be fastened to the upper surface of the support plate 10 by bolts. Finally, the upper connecting plate 14 on the outer side of the side plate 2 is fastened to the lower connecting plates 15 on both sides of the base 1 by bolts and nuts to complete the installation. In use, damp leather is placed on the feeding tray 8 and manually fed by pushing the back of the leather, avoiding the need to grip the front of the leather for feeding. The hydraulic cylinder 5 drives the lifting frame 11 to descend and leaves a gap between the pressure roller 12 and the support roller 6. The hydraulic cylinder 5 is connected to the pump station. After the leather enters between the pressure roller 12 and the support roller 6, the reduction motor 18 is started. The reduction motor 18 drives the support roller 6 to rotate, thereby realizing the forward movement of the leather. During the forward movement of the leather, the water is squeezed out by the cooperation of the pressure roller 12 and the support roller 6. This utility model has a reasonable structure. First, the upper surface of the base 1 on both sides of the water receiving tank 4 is provided with upright plates 7. When the side plates 2 are connected to the base 1, the upright plates 7 can prevent water from splashing out from both ends of the equipment. Furthermore, the feed tray 8 and the discharge tray 9 are respectively supported on the upright plates 7, which also improves the support of the feed tray 8 and the discharge tray 9, thereby ensuring the stability during feeding and discharging. At the same time, support plates 10 are provided on both sides of the side plates 2, and the feed tray 8 and the discharge tray 9 are supported on the support plates 10 on both sides of the outer ends of the side plates 2. This further improves the support of the feed tray 8 and the discharge tray 9; the upper surface of the feed tray 8 and the discharge tray 9 near the support roller 6 is inclined, so that water will not overflow from the feed tray 8 and the discharge tray 9 when squeezing water; since the water receiving area is closed by the vertical plate 7, the side plate 2, the feed tray 8 and the discharge tray 9, the upper connecting plate 14 of the side plate 2 is connected to the lower connecting plate 15 of the base 1 by bolts and nuts, and the connection is detachable, which makes it easy to open and clean the water receiving tank 4 of the base 1.
