Description

Technical Field

[0001] The invention relates to the technical field of press equipment, and in particular to a pressing and screening device for squeezing sugarcane juice. Background Art

[0002] In the sugarcane processing industry, sugarcane juice extraction is crucial, and the performance of the pressing device as the core equipment directly determines the output and quality of sugarcane juice. With the continuous growth of market demand for sugarcane juice and related products, improving the efficiency and effect of sugarcane extraction has become the focus of the industry.

[0003] At present, the common sugarcane squeezing devices on the market are mainly of two types: roller press and screw press. The roller press squeezes the sugarcane through multiple sets of rollers to make the sugarcane juice flow out. However, this method has obvious disadvantages. Due to the limitations of the roller structure and squeezing method, the sugarcane cannot be fully and evenly squeezed when passing through the roller gap, and a large amount of sugarcane juice will still be wrapped between the sugarcane fibers, resulting in a lot of sugarcane juice remaining in the squeezed sugarcane, and the sugarcane juice extraction rate is low. The screw press relies on a screw propeller to push the sugarcane to the outlet, squeezing the sugarcane in the process. However, in actual operation, this device is also difficult to achieve the ideal squeezing effect. The pressure distribution of the screw propeller is not uniform, and the sugarcane close to the feed port is under less pressure, making it difficult to fully squeeze out the internal sugarcane juice.

[0004] Whether it is a roller press or a screw press, existing sugarcane pressing devices generally have the problem of poor pressing effect, and therefore are in urgent need of improvement. Summary of the invention

The main pressing roller 13 and the auxiliary pressing roller 14 arranged on the main pressing shaft 8 and the auxiliary pressing shaft 11 rotate, thereby driving the auxiliary blocks 24 arranged on the main pressing roller 13 and the auxiliary pressing roller 14 to rotate, so that the main pressing sleeve 15 and the auxiliary pressing sleeve 16 fixedly connected to the auxiliary blocks 24 on the main pressing roller 13 and the auxiliary pressing roller 14 respectively rotate, and then the pressure tooth groups 17 arranged on the main pressing sleeve 15 and the auxiliary pressing sleeve 16 respectively rotate around the axis of the main pressing sleeve 15 and the axis of the auxiliary pressing sleeve 16, and the pressure tooth groups 17 arranged on the main pressing sleeve 15 and the auxiliary pressing sleeve 16 are engaged, so that the sugar cane is squeezed once; The sugar cane after the first squeezing moves to the meshing position of the pressure tooth group 17 on the main squeezing sleeve 15 and the pressure tooth group 17 on the auxiliary squeezing sleeve 16 near the side of the reballast block 26 under the action of the first guide block 30, and then the meshing position between the pressure tooth group 17 on the main squeezing sleeve 15 and the auxiliary squeezing sleeve 16 near the side of the reballast block 26 is achieved, thereby realizing the second squeezing of the sugar cane after the first squeezing; The device uses a squeezing mechanism to perform secondary squeezing of sugarcane, effectively improving the juice yield of sugarcane, thereby improving the squeezing effect of the device on sugarcane; Reference Figures 1 to 12 The auxiliary part is used to assist the pressing part to better press the sugarcane, and includes: A main electric push rod 18 is disposed on the carrier 1 and is electrically connected to the control device 2; Auxiliary electric push rods 19, including two groups, and the two groups of auxiliary electric push rods 19 are arranged on the surface of the supporting frame 1 on the opposite side of the main electric push rod 18, and the auxiliary electric push rods 19 are electrically connected to the control device 2; A main end plate 20 is slidably disposed on the main pressing roller 13 and fixedly connected to one end of the main pressing sleeve 15 close to the main electric push rod 18. The main end plate 20 is used to drive the main pressing sleeve 15 to slide on the main pressing roller 13; A secondary end plate 21 is slidably disposed on the secondary pressing roller 14 and is fixedly connected to one end of the secondary pressing sleeve 16 close to the secondary electric push rod 19. The secondary end plate 21 is used to drive the secondary pressing sleeve 16 to slide on the secondary pressing roller 14; Auxiliary grooves 22 are provided on the surfaces of the main pressing roller 13 and the auxiliary pressing roller 14; An auxiliary rod 23, fixedly disposed in the auxiliary groove 22; The auxiliary block 24 is slidably disposed in the auxiliary groove 22 and is slidably connected to the auxiliary rod 23. The auxiliary block 24 disposed on the main pressure roller 13 is fixedly connected to the main pressing sleeve 15, and the auxiliary block 24 disposed on the main pressure roller 13 is initially located at one end of the auxiliary groove 22 close to the main electric push rod 18. The auxiliary block 24 disposed on the auxiliary pressure roller 14 is fixedly connected to the auxiliary pressing sleeve 16, and the auxiliary block 24 disposed on the auxiliary pressure roller 14 is initially located at one end of the auxiliary groove 22 close to the auxiliary electric push rod 19; The auxiliary spring 25 is sleeved on the auxiliary rod 23, and the auxiliary spring 25 is always in a compressed state. By providing the auxiliary spring 25, after the auxiliary block 24 loses the force of the main electric push rod 18 or the auxiliary electric push rod 19, the compressed auxiliary spring 25 releases elastic potential energy, so that the auxiliary block 24 moves away from the auxiliary spring 25, and cooperates with the main electric push rod 18 or the auxiliary electric push rod 19 to push the auxiliary block 24, thereby realizing the reciprocating relative movement of the main pressing sleeve 15 and the auxiliary pressing sleeve 16.

[0038] Reference Figures 1 to 12When the pressure teeth group 17 arranged on the main pressing sleeve 15 and the pressure teeth group 17 arranged on the auxiliary pressing sleeve 16 are pressing the sugarcane, the staff can also control the main electric push rod 18 and the auxiliary electric push rod 19 to start through the control device 2, so that the auxiliary blocks 24 adjacent to the main electric push rod 18 and the auxiliary electric push rod 19 slide in the auxiliary groove 22, so that the main pressing sleeve 15 fixedly connected to the auxiliary block 24 rotates around the axis of the main pressing roller 13 and the auxiliary pressing sleeve 16 rotates around the axis of the auxiliary pressing roller 14, and the main pressing sleeve 15 and the auxiliary pressing sleeve 16 can also move relatively on the surfaces of the main pressing roller 13 and the auxiliary pressing roller 14 respectively, so that the main pressing sleeve 15 and the auxiliary pressing sleeve 16 can move relatively on the surfaces of the main pressing roller 13 and the auxiliary pressing roller 14 respectively. While the pressure tooth group 17 on the pressing sleeve 15 rotates around the axis of the main pressing roller 13 and the pressure tooth group 17 on the auxiliary pressing sleeve 16 rotates around the axis of the auxiliary pressing roller 14, the pressure tooth group 17 on the main pressing sleeve 15 and the pressure tooth group 17 on the auxiliary pressing sleeve 16 can also move relatively, so that the pressure tooth group 17 can exert a lateral tearing force on the sugarcane while pressing the sugarcane, dispersing the initially crushed sugarcane stalks on the main pressing roller 13 and the auxiliary pressing roller 14, avoiding the broken sugarcane stalks from piling up, so that the pressure during subsequent pressing can act more directly on each broken sugarcane stalk, further improving the pressing effect of the pressing mechanism on the sugarcane.

[0039] It should be noted that the device is provided with an auxiliary part, so that the pressure tooth group 17 can exert a tearing force on the sugarcane while squeezing the sugarcane, thereby facilitating the pressure tooth group 17 to tear the sugarcane, and to a certain extent increasing the contact area between the sugarcane and the pressure tooth group 17, thereby further improving the squeezing effect of the squeezing mechanism on the sugarcane.

[0040] Reference Figures 1 to 12 A re-pressing mechanism is provided on the carrier frame 1 and is electrically connected to the control device 2.

The surface of the re-pressure block 29 close to the re-ballast block 26 is also arranged as an arc surface, and the inclined surface on the re-pressure block 29 is in contact with the inclined surface on the re-ballast block 26. It should be noted that by setting the surface of the re-ballast block 26 away from the screening mechanism as a curved surface and the surface of the re-pressing block 29 close to the re-ballast block 26 as a curved surface, the contact area between the sugarcane after the secondary pressing by the pressing mechanism and the re-ballast block 26 and the re-pressing block 29 is increased to a certain extent, thereby improving the pressing effect of the re-pressing mechanism on the sugarcane to a certain extent.

[0041] The sugarcane that has been squeezed for the second time moves between the reballast block 26 and the re-pressing block 29 under the action of the limit block 31 and the second guide block 32. When the sugarcane that has been squeezed for the second time moves between the reballast block 26 and the re-pressing block 29, the control device 2 controls the hydraulic push rod 28 to start, so that the re-pressing block 29 fixedly connected to the hydraulic push rod 28 moves toward the direction of the reballast block 26 until the re-pressing block 29 contacts the reballast block 26, thereby completing the re-pressing operation of the sugarcane after the second squeezing. It should be noted that, by providing a re-pressing mechanism, the device can re-press the sugarcane after the second pressing by the pressing mechanism. Through the action between the arc surface on the re-pressing block 29 and the arc surface on the re-ballast block 26, the sugarcane after the second pressing can fully contact with the re-pressing block 29 and the re-ballast block 26, and then the juice still remaining in the sugarcane after the second pressing can be squeezed out, thereby further improving the squeezing effect of the device.
