Abstract

This utility model discloses a high-efficiency forced-entry front roller and pressing device, relating to the field of sugarcane production and processing technology. It includes a roller body with rotating shafts at both ends. Multiple circumferential bosses are arrayed along the axis of the roller body surface, forming annular drainage grooves between adjacent bosses. The key feature is that multiple first V-shaped grooves are arrayed circumferentially on the surface of each circumferential boss. The first V-shaped grooves on the same generatrix of the multiple circumferential bosses form a group, and each group of first V-shaped grooves is distributed in a herringbone pattern on the roller body surface. By opening first and second V-shaped grooves on the circumferential bosses, the sugarcane will be caught in the first and second V-shaped grooves during the rotation of the roller body and driven by them. This overcomes the defect in actual production where sufficient static friction cannot be formed between the sugarcane surface and the roller, making it difficult for the sugarcane to be smoothly rolled into the rollers.

Description

Technical Field

[0001] This utility model belongs to the field of sugarcane production and processing technology, and specifically relates to a high-efficiency forced-feed front roller and pressing device. Background Technology

[0002] In sugarcane sugar production, the pressing process is the core link that determines the sugar yield and production efficiency. It mainly uses the relative sliding of multiple sets of rollers to generate squeezing force, separating the juice from the sugarcane stalks. The feeding process of existing pressing equipment mainly relies on the friction between the roller surface and the sugarcane. When the rollers rotate, they automatically roll the sugarcane into the roller space, and the sugarcane is pressed through the interlaced squeezing grooves of multiple rollers.

[0003] However, in actual production, a significant defect was found in this feeding method: due to uneven thickness, surface moisture, or uneven fiber distribution in the sugarcane raw material, some sugarcane cannot generate sufficient static friction with the rollers when it comes into contact with them, resulting in relative sliding between the sugarcane and the rollers. This relative sliding makes it difficult for the sugarcane to be smoothly rolled into the rollers. In order to wait for the sugarcane to be rolled into the rollers and to avoid overloading the pressing machine, the feeding speed needs to be reduced, but this will affect the overall efficiency of sugarcane pressing. Therefore, a high-efficiency forced-feed type front roller and pressing device are needed. Utility Model Content

[0004] The purpose of this invention is to provide a highly efficient forced-feed front roller and pressing device. By opening a first V-shaped groove and a second V-shaped groove on the circumferential boss to increase the contact area with the sugarcane, the sugarcane will be caught in the first and second V-shaped grooves and driven by them during the rotation of the roller body. This overcomes the defect in actual production where sufficient static friction cannot be formed between the sugarcane surface and the roller, making it difficult for the sugarcane to be smoothly rolled into the rollers. The specific technical solution is as follows: A high-efficiency forced feed type front roll includes a roll body with rotating shafts at both ends. Multiple circumferential bosses are arrayed along the axis of the roll body surface, and annular drainage grooves are formed between adjacent circumferential bosses. Multiple first V-shaped grooves are arrayed circumferentially on the surface of the circumferential bosses. The first V-shaped grooves on the same generatrix of the multiple circumferential bosses form a group, and each group of first V-shaped grooves is distributed in a herringbone pattern on the surface of the roll body.

[0005] Preferably, the first V-groove includes a first short side and a first long side, and the extension line of the first short side is perpendicular to the axis of the roll body.

[0006] Preferably, the included angle of the herringbone shape formed by each group of the first V-grooves is in the same direction as the rotation direction of the roll body, and the end of the first long side away from the first short side is in the same direction as the rotation direction of the roll body.

[0007] Preferably, the length of the first short side of the first V-groove is 2-3 cm, and the angle between the first short side and the first long side is 80-90 degrees.

[0008] Preferably, a plurality of second V-shaped grooves are evenly provided between the first V-shaped grooves on the circumferential boss, and the shape of the second V-shaped grooves is similar to that of the first V-shaped grooves.

[0009] Preferably, the second V-groove includes a second short side and a second long side, wherein the length of the second short side is half the length of the first short side.

[0010] Preferably, the number of the second V-grooves is 2-4.

[0011] A pressing device includes the aforementioned high-efficiency forced-infeed type front roller, wherein the axes of several of the high-efficiency forced-infeed type front rollers are parallel to each other in space, the circumferential bosses of adjacent high-efficiency forced-infeed type front rollers match the juice discharge grooves and leave gaps, and the included angles of the herringbone shape formed by the first V-shaped grooves on adjacent high-efficiency forced-infeed type front rollers are opposite.

[0012] Compared with existing technologies, this utility model has the following beneficial effects: 1. This utility model has a first V-shaped groove on the circumferential boss, with the length of the first short side being similar to the radius of the sugarcane. When the roller body rotates, the sugarcane can be stuck into the first V-shaped groove and fixed, thereby driving the sugarcane to move and reducing the relative sliding between the sugarcane and the roller body. This allows the sugarcane to be stably and quickly rolled into the rollers, thereby increasing the feeding speed of the pressing device and improving the production efficiency of the pressing device.

[0013] 2. This invention also includes multiple second V-shaped grooves evenly spaced between the first V-shaped grooves, further increasing the friction between the roller body and the sugarcane, and further improving the efficiency of sugarcane being rolled into the rollers. Since adding grooves to the circumferential boss will affect the juice yield of the sugarcane, using a combination of the first and second V-shaped grooves, with the length of the second short side being half the length of the first short side, can effectively balance the two, improving production efficiency while ensuring the juice yield of the sugarcane and avoiding a decrease in sugarcane utilization.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] A sugarcane press is a device that separates the juice from the sugarcane stalk through mechanical compression. Its core principle is to use pressure to break down the sugarcane's fibrous structure, causing the juice to flow out of the cells and simultaneously separating the juice from the bagasse. The sugarcane stalk consists of fibrous cell walls, cell sap (containing sugar), and vascular bundles, with the juice primarily stored within the cells. The core component of the press applies high-intensity pressure to the sugarcane entering the equipment. When the pressure exceeds the cell walls' tolerance limit, the cell walls rupture, and the juice flows out naturally, forming "crude juice."

[0022] Next reference Figures 1 to 4 The working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model: A high-efficiency forced-in front roll includes a roll body 1, with rotating shafts 2 at both ends of the roll body 1. The rotating shafts 2 are used to connect to drive elements and transmit kinetic energy for the rotation of the roll body 1. Multiple circumferential bosses 3 are arrayed along the axis on the surface of the roll body 1, and annular juice discharge grooves are formed between adjacent circumferential bosses 3. By aligning the circumferential bosses 3 of the roll body 1 with the juice discharge grooves of adjacent roll bodies 1, when sugarcane is rolled into the roll, the circumferential bosses 3 and the juice discharge grooves cooperate to squeeze the sugarcane, and the squeezed sugarcane juice flows away along the juice discharge grooves. The circumferential boss 3 has multiple first V-shaped grooves 4 arranged in a circular array on its surface. The first V-shaped grooves 4 can increase the contact area between the roller body 1 and the sugarcane, thereby increasing the friction between the two. When the roller body 1 rotates, the sugarcane can be stuck into the first V-shaped grooves 4 and fixed, thereby driving the sugarcane to move and reducing the relative sliding between the sugarcane and the roller body 1. This allows the sugarcane to be stably and quickly rolled into the rollers, thereby increasing the feeding speed of the pressing device and improving the production efficiency of the pressing device.

[0023] Multiple circumferential bosses 3 form a group of first V-shaped grooves 4 on the same generatrix. Each group of first V-shaped grooves 4 is distributed in a herringbone pattern on the surface of the roll body 1. The included angle of the herringbone pattern formed by each group of first V-shaped grooves 4 is in the same direction as the rotation direction of the roll body 1. In the pressing device, the included angle of the herringbone pattern formed by the first V-shaped grooves 4 on two adjacent roll bodies 1 is opposite, and their rotation directions are opposite. Therefore, when they cooperate, they will generate pushing and pulling forces on the sugarcane respectively, forming a resultant force, thereby increasing the feed force and making it easier to push the sugarcane forward. Therefore, the herringbone distribution design can further improve the working efficiency of the pressing device.

[0024] The first V-groove 4 includes a first short side 42 and a first long side 41. The extension line of the first short side 42 is perpendicular to the axis of the roll body 1. The end of the first long side 41 away from the first short side 42 is oriented in the same direction as the rotation of the roll body 1, so that the force of the short side on the sugarcane is a thrust, and the thrust is tangential to the rotation of the roll body 1, which facilitates pushing the sugarcane into the roll space.

[0025] The diameter of mature sugarcane after juicing is generally 2.5-4.5 cm. Therefore, setting the length of the first short side 42 of the first V-groove 4 to 2-3 cm can provide good support for the sugarcane and enhance the ability of the first V-groove 4 to drive the sugarcane. The angle between the first short side 42 and the first long side 41 is 80-90 degrees, which can ensure that the long side is in full contact with the sugarcane, increase friction, and at the same time make the center of the sugarcane closer to the axis of the roller body 1, making it easier to be driven by the first V-groove 4.

[0026] Multiple second V-shaped grooves 5 are evenly distributed between the first V-shaped grooves 4 on the circumferential boss 3. The shape of the second V-shaped grooves 5 is similar to that of the first V-shaped grooves 4. The proportions of the second long side 51 and the second short side 52 to the first long side 41 and the second long side 51 are the same, both being half, and the included angles are also the same. The second V-shaped grooves 5 can further increase the friction between the roller body 1 and the sugarcane, further improving the efficiency of sugarcane being rolled into the rollers. The number of second V-shaped grooves 5 is 2-4. Since adding grooves on the circumferential boss 3 will increase the gap between the circumferential boss 3 and the juice discharge groove, affecting the juice yield of sugarcane, the combination of the first V-shaped grooves 4 and the second V-shaped grooves 5, with the length of the second short side 52 being half the length of the first short side 42, can effectively balance the two, thereby achieving a high output exceeding the original design output of the machine.

[0027] During long-term production operations, the applicant discovered that one of the reasons for the limited production efficiency of the old equipment was that the speed at which the rollers rolled into the sugarcane affected the feeding speed, rather than the equipment itself reaching its maximum load limit. After meeting the initial design workload, the equipment still had a large load margin. Therefore, by adopting the above-mentioned technical features, the juice discharge efficiency and the pressing efficiency of the pressing device can be improved without adding or replacing the equipment. These technical features are also applicable to new technologies.
