DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] In order to solve the technical problem of high production and maintenance costs caused by two motors driving the upper drum and the lower drum respectively, the utility model provides a cotton press that can reduce production and maintenance costs.

[0022] It should be noted that the cotton press described in the present invention is used for but not limited to cotton presses, etc. For the convenience of explanation, in the present invention, only a cotton press is used in a cotton press as an example for explanation. The principle of a cotton press being used in other types of equipment is essentially the same as the principle used in a cotton press, and will not be described one by one here.

[0023] See also Figure 1 - Figure 2 ,in Figure 1 This is a structural schematic diagram of a cotton press in one embodiment of the utility model, a cotton press includes a frame 1, a lower shaft roller 2, an upper shaft roller 3, a motor 4 and a lifting member 5, the lower shaft roller 2 is rotatably connected to the top of the frame 1, one end of the lower shaft roller 2 is fixedly connected to the lower gear 21, the upper shaft roller 3 is rotatably connected to the top of the lower shaft roller 2, one end of the upper shaft roller 3 is fixedly connected to the universal joint 32 and the upper gear 31 in sequence, the upper gear 31 is meshed with the lower gear 21, the motor 4 is connected to the lower gear 21 and is used to drive the lower gear 21 to rotate, the lifting member 5 is connected to the upper shaft roller 3 and is used to drive the upper shaft roller 3 to rise and fall.

[0024] In this embodiment, the universal joint 32 is provided so that the upper gear 31 will not be affected when the lifting member 5 drives the upper roller 3 to rise and fall, thereby ensuring that the upper gear 31 and the lower gear 21 are always in a meshing state, thereby achieving that the device only requires one motor 4 to drive the upper gear 31 and the lower gear 21 to run at the same speed (that is, the upper roller 3 and the lower roller 2 run at the same speed), effectively reducing production costs and maintenance costs.

[0025] Furthermore, a universal joint 32 is also installed between the lower roller 2 and the lower gear 21 .

[0026] In one embodiment, see Figure 1 - Figure 2 The lifting member 5 includes a vertical plate 51 and a slide 52. The vertical plate 51 is installed with a slide rail 511. One side of the slide 52 is fixedly connected to a pair of first hinged plates 522. The upper shaft roller 3 is rotatably connected between the two first hinged plates 522. The other side of the slide 52 is fixedly connected to a slider 521, and the slider 521 is slidably embedded in the slide rail 511.

[0027] In one embodiment, see Figure 1 - Figure 2 The lifting member 5 further includes a screw 53 , the slide plate 52 is provided with a threaded hole 523 , and the screw 53 is threadedly connected to the threaded hole 523 .

[0028] In this embodiment, the upper and lower ends of the vertical plate 51 are fixedly connected to the mounting plates, and the two ends of the screw 53 are respectively rotatably connected to the two mounting plates. Under the action of the threaded connection between the screw 53 and the threaded hole 523, the screw 53 itself does not displace during the rotation process but the slide plate 52 displaces, thereby realizing the lifting function of the upper shaft roller 3. The setting of the slider 521 and the slide rail 511 makes the upper shaft roller 3 more stable during the lifting process, thereby enabling the device to change the center distance between the upper shaft roller 3 and the lower shaft roller 2, that is, to process sponges of different thicknesses.

[0029] In one embodiment, see Figure 1 The top end of the screw rod 53 is fixedly connected with a hand wheel 531 .

[0030] In this embodiment, the hand wheel 531 is used to facilitate the operator to manually rotate the screw 53 .

[0031] In one embodiment, see Figure 1 - Figure 2 One end of the slide plate 52 is fixedly connected to a fixed plate 54 , and the fixed plate 54 is provided with a slideway 541 . A knob 512 is installed at one end of the vertical plate 51 , and one end of the knob 512 passes through the slideway 541 and is used to fasten the fixed plate 54 .

[0032] In this embodiment, one end of the knob 512 is threadedly connected to one end of the vertical plate 51, and the other end of the knob 512 is provided with a convex ring and is used to press the fixing plate 54, thereby preventing the upper shaft roller 3 from shaking during the sponge processing process.

[0033] Furthermore, the knob 512 is fixedly connected to a handle to facilitate the operator to manually twist the knob 512 .

[0034] In one embodiment, see Figure 1 - Figure 2 The outer walls of the upper gear 31 and the lower gear 21 are sheathed with a housing 6.

[0035] In this embodiment, the housing 6 serves to protect the upper gear 31 and the lower gear 21 .

[0036] In one embodiment, see Figure 1 - Figure 2 The output end of the motor 4 is fixedly connected to a synchronous wheel 41 , and the synchronous wheel 41 is fixedly connected to the lower gear 21 .

[0037] In this embodiment, the function of the synchronous wheel 41 is to transmit the power of the output end of the motor 4 to the lower gear 21, and then the lower gear 21 engages with the upper gear 31 to achieve synchronous operation of the upper roller 3 and the lower roller 2.

[0038] In one embodiment, see Figure 1 - Figure 2 A pair of second hinge plates 11 are fixedly connected to the top of the frame 1, and the lower shaft roller 2 is rotatably connected between the two second hinge plates 11.

[0039] In this embodiment, the second hinge plate 11 is used to install the lower shaft roller 2 .

[0040] In one embodiment, see Figure 1 - Figure 2 The outer fixed sleeve of the frame body 1 is provided with a frame 7.

[0041] In this embodiment, the function of the frame 7 is to protect the device, and the side walls of the frame 7 are provided with door panels, so that maintenance personnel can open the door panels to inspect the device.

[0042] It should be noted that a through hole is provided on the top of the frame 7, and the through hole is located between the upper roller 3 and the lower roller 2, so that the lower roller 2 can cooperate with the upper roller 3 after passing through the through hole to realize the processing of the sponge.

[0043] In one embodiment, see Figure 1 A universal wheel 71 is installed at the bottom of the frame 7.

[0044] In this embodiment, the function of the universal wheel 71 is to facilitate the movement of the device, and in order to ensure the stability of the device during the processing, the universal wheel 71 has a locking function.

[0045] In order to better understand the present invention, the following Figures 1 to 2 The technical solution of the utility model is described in detail:

[0046] First, according to the thickness of the sponge to be processed, manually rotate the handwheel 531 to make the screw 53 rotate and drive the slide plate 52 and the upper roller 3 to rise and fall to a preset height, and the universal joint 32 bends as the height of the upper roller 3 changes; then, manually tighten the knob 512 so that the knob 512 presses the fixing plate 54, and the debugging of the upper roller 3 is completed; finally, the motor 4 is started, and the motor 4 drives the synchronous wheel 41 to rotate, and the synchronous wheel 41 drives the lower gear 21 and the upper gear 31 to rotate together, thereby realizing the same speed operation of the lower roller 2 and the upper roller 3, and the sponge processing can be started. In the utility model, only one motor 4 is required to drive the upper gear 31 and the lower gear 21 to run at the same speed (that is, the upper roller 3 and the lower roller 2 run at the same speed), and there is no need for multiple motors 4 and the same speed control system, which effectively reduces the production cost and maintenance cost.

[0047] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
