Description

Technical Field

[0001] This utility model belongs to the technical field of sugarcane juicing devices, specifically relating to a sugarcane press suitable for various sugarcane diameters. Background Technology

[0002] Sugarcane, as a core raw material for the sugar industry and a popular fresh food crop, directly impacts the economic benefits of related industries and consumer experience through the efficiency and quality of its juice extraction. In sugarcane processing and consumption scenarios, sugarcane presses are key equipment for achieving efficient juice extraction and are widely used in small sugar workshops, fruit processing stalls, and for home use.

[0003] However, most small sugarcane presses currently on the market suffer from structural design limitations, with the core issue being the lack or inadequacy of the roller spacing adjustment function. Because sugarcane diameters vary significantly between different varieties and growth stages, and traditional presses typically have fixed drive and driven rollers with no adjustable spacing based on the sugarcane diameter, when processing coarse sugarcane with a diameter larger than the roller spacing, the sugarcane easily gets stuck between the rollers, preventing proper pressing and potentially causing motor damage or roller deformation due to overload. When processing fine sugarcane with a diameter smaller than the roller spacing, the rollers cannot effectively compress the sugarcane, leaving a large amount of juice in the bagasse, significantly reducing pressing efficiency and resulting in raw material waste.

[0004] In summary, existing small sugarcane presses are difficult to adapt to the pressing needs of sugarcane of various diameters due to the non-adjustable roller spacing or unreasonable adjustment methods. They also suffer from problems such as low juicing efficiency, inconvenient operation, and insufficient food safety assurance. There is an urgent need for a sugarcane press that can automatically adapt the roller spacing, achieve high pressing efficiency, and be easy to use to meet the needs of actual production and consumption scenarios. Utility Model Content

[0005] In order to overcome the problems in the prior art, this utility model provides a sugarcane press suitable for various sugarcane diameters.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A sugarcane press suitable for various sugarcane diameters, comprising:

[0008] The body has an upper shell mounted on its upper part. The upper shell consists of two vertical plates arranged symmetrically on the left and right and a cover plate fixed to the top of the two vertical plates. The two vertical plates are vertical and relatively parallel.

[0009] A roller mechanism is disposed between the two vertical plates. The roller mechanism includes a driving roller, a driven roller, and a movable roller. The driving roller, driven roller, and movable roller all extend horizontally, and their two ends are integrally formed with coaxial rotating shafts. The rotating shafts of the driving roller and the driven roller are respectively installed in corresponding circular holes in the two vertical plates through bearings, and one end of the rotating shaft of the driving roller passes through one of the vertical plates and extends to the outside of the machine body.

[0010] The movable component, as the core component for adjusting the distance between the rollers, has its rotating shaft mounted on two vertical plates via the movable component. The movable component includes an outer ring, an inner ring, and multiple compression springs. The outer ring is annular and fixedly embedded in a circular hole in the vertical plate. The inner ring is sleeved on the rotating shaft of the movable roller and forms a rotational engagement with the shaft. The multiple compression springs are evenly distributed in an array along the circumferential direction between the outer ring and the inner ring, and the two ends of each compression spring are fixedly connected to the inner side wall of the outer ring and the outer side wall of the inner ring, respectively. The distance between the movable roller and the driving roller and the driven roller is adjusted by the extension and retraction of the compression springs.

[0011] Furthermore, a drive assembly is provided on the outer side of the machine body. The drive assembly is connected to the drive roller shaft extending to the outside of the machine body. It is used to drive the drive roller to rotate and drive the driven roller to rotate synchronously, so as to cooperate with the movable roller to complete the pressing operation of sugarcane of different diameters.

[0012] Furthermore, the inner wall of the outer ring is an equilateral polygon structure, and the end of the compression spring is fixed to the plane of the equilateral polygon structure by welding; through the elastic deformation of the compression spring, the movable component can form an adjustable gap of 3-5mm between the movable roller and the driving roller, and between the movable roller and the driven roller, to accommodate sugarcane with a diameter difference of 3-5mm that extends into the press.

[0013] Furthermore, the driving roller and the driven roller are spaced apart in the horizontal direction, and their axes are on the same horizontal plane; the movable roller is located directly above the driving roller and the driven roller, and the axis of the movable roller forms an isosceles triangle with the axes of the driving roller and the driven roller to improve the force balance and stability during sugarcane pressing.

[0014] Furthermore, the drive assembly includes a drive motor, a reducer, a drive pulley, a synchronous pulley, and a driven pulley. The synchronous pulley is fixedly mounted on the rotating shaft extending from the drive roller to the outside of the machine body via a key connection. The driven pulley is fixedly mounted on the rotating shaft extending from the driven roller to the outside of the machine body via a key connection. The synchronous pulley and the driven pulley are tensioned and connected by a first belt. The bottom of the machine body has a cavity. The reducer is fixedly installed in the cavity by bolts. The output shaft of the drive motor is connected to the input end of the reducer via a coupling. The drive pulley is fixedly mounted on the output end of the reducer. The drive pulley and the synchronous pulley are tensioned and connected by a second belt, thereby realizing the speed reduction transmission of the drive motor to the roller mechanism.

[0015] Furthermore, the cover plate has a feed inlet on one side and a discharge chute on the other side; the feed inlet is inclined, and the outlet end of the feed inlet is directly opposite the gap between the active roller and the movable roller, which is used to guide the sugarcane to accurately extend into the roller mechanism; the discharge chute is inclined downward, which is used to guide the pressed sugarcane bagasse to be discharged.

[0016] Furthermore, the top of the machine body is provided with an opening, and a filter plate is slidably installed at the opening; the filter plate is a rectangular frame structure, and a filter screen is embedded inside. The filter screen has a pore size of 0.5-1mm and is used to filter coarse fiber residue in the sugarcane juice; an inclined plate is provided below the filter plate, and the inclined plate is inclined. A bend pipe is welded to the center of the bottom of the inclined plate. A pipe valve is installed on the bend pipe. After being filtered by the filter screen, the sugarcane juice falls onto the inclined plate and converges along the inclined surface of the inclined plate into the bend pipe. Opening the pipe valve can realize the quantitative collection of juice.

[0017] Furthermore, the circular holes on the upright plate are divided into two types: two horizontally arranged mounting holes and one fixed hole located directly above the mounting holes; the rotating shafts of the driving roller and the driven roller are respectively installed in the mounting holes via bearings, and the outer ring of the movable component is fixedly embedded in the fixed hole; a fixing groove is formed on the top inner wall of the fixed hole, and a fixing block that matches the fixing groove is integrally formed on the outer outer wall of the outer ring. When the outer ring is embedded in the fixed hole, the fixing block is embedded in the fixing groove to form a circumferential limit and prevent the outer ring from rotating in the fixed hole.

[0018] Furthermore, the inner side of the movable component is provided with a sealing plate. The sealing plate is a circular plate structure and is fixed to the inner wall of the upright plate by bolts. The diameter of the sealing plate is larger than the diameter of the fixed circular hole, which can completely cover the fixed circular hole. A circular through hole is opened in the center of the sealing plate. The diameter of the through hole is 2-6 cm larger than the diameter of the movable roller shaft. When the movable roller moves up and down, its shaft always moves within the range of the through hole, preventing sugarcane juice from overflowing from the gap between the fixed circular hole and the shaft.

[0019] The beneficial effects of this utility model are:

[0020] (1) Adaptable to various sugarcane diameters, improving the versatility of pressing: This patent uses a movable component consisting of an outer ring, an inner ring, and multiple compression springs. The rotating shaft of the movable roller is installed in the inner ring of the movable component. The elastic force of multiple compression springs evenly distributed along the circumference is used to automatically adjust the distance between the movable roller and the driving roller and the driven roller. When processing coarse sugarcane, the sugarcane squeezes the movable roller, pushing the inner ring to compress the spring at the corresponding position, increasing the roller distance and ensuring that the coarse sugarcane passes through smoothly and is effectively squeezed. When processing fine sugarcane, the spring resets and pushes the inner ring, reducing the roller distance and ensuring that the fine sugarcane can also be fully squeezed. It can adapt to sugarcane of different diameters without manual adjustment, completely solving the problem of coarse sugarcane getting stuck and fine sugarcane not being fully squeezed due to the fixed distance in traditional presses, and greatly improving the versatility and applicability of the equipment.

[0021] (2) The structure is reasonably designed, easy to operate and maintain: The inclined feed inlet on one side of the cover plate is directly opposite the gap between the active roller and the movable roller, which can guide the sugarcane to accurately enter the roller mechanism without the need for manual adjustment of the sugarcane position, reducing the difficulty of operation; the inclined discharge chute on the other side can automatically guide the pressed sugarcane bagasse to be discharged, avoiding the accumulation of waste residue and realizing continuous pressing operation. The filter plate that is slidably installed on the top of the machine body has a filter screen embedded inside that can effectively filter the coarse fiber waste residue in the juice without the need for additional filtration steps; the filter plate can be directly pulled out from the top of the machine body, which is convenient for cleaning or replacing the filter screen, making operation convenient; at the same time, the sealing plate inside the movable component can completely cover the fixed round hole on the vertical plate, and the through hole in the center of the sealing plate is adapted to the movement range of the movable roller shaft, which effectively prevents the sugarcane juice from overflowing from the gap between the fixed round hole and the shaft, reducing the residue residue inside the equipment, reducing the difficulty of cleaning, and facilitating daily maintenance.

[0022] (3) Stable drive transmission and extended equipment service life: The drive assembly adopts a drive motor and reducer transmission method. After the motor speed is reduced by the reducer, the drive roller is driven to rotate by belt transmission. This can effectively reduce the speed of the drive roller and increase the output torque. It avoids the problem of excessive speed and insufficient torque caused by direct motor drive, and ensures that the equipment can operate stably when pressing coarse sugarcane, reducing the risk of motor overload damage. At the same time, the synchronous pulley and the driven pulley are connected by the first belt tensioning to ensure the synchronous rotation of the drive roller and the driven roller, avoiding sugarcane wear or equipment vibration caused by roller speed difference, reducing friction loss between components and extending the overall service life of the equipment.

Detailed Implementation

[0032] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] See Figures 1 to 7 This utility model discloses a sugarcane press suitable for various sugarcane diameters. The sugarcane press mainly includes a body 1, an upper shell 2, a roller mechanism 3, a movable component 4, a drive component 5, and a sealing plate 6. The components work together to solve the problems of traditional sugarcane presses, such as non-adjustable roller spacing, poor adaptability, and low juicing efficiency. It achieves stable pressing and juice collection of sugarcane of different diameters. The specific structure, connection relationship, function, and overall working method of each component are described in detail below.

[0034] The machine body 1 is the basic load-bearing component of the entire press, providing a stable mounting platform for all components and ensuring that the equipment does not shake during the pressing process. The upper part of the machine body 1 has a reserved mounting structure that is compatible with the upper shell 2 for precise assembly of the upper shell 2 and to prevent the upper shell 2 from shifting laterally during operation. The bottom of the machine body 1 has a closed cavity with reserved mounting positions for fixing key components in the drive assembly 5, ensuring the stability of the drive assembly during operation. The top of the machine body 1 has a rectangular opening 11 with a slide rail on the inner wall for sliding the filter plate 12. This facilitates the daily removal and insertion of the filter plate 12 and provides convenient operating space for subsequent cleaning or replacement of the filter screen, solving the problem of cumbersome disassembly of the filter structure in traditional equipment.

[0035] The upper housing 2 protects the roller mechanism 3 and guides the sugarcane in and out. It consists of two symmetrical upright plates 21 and a cover plate 22 that covers the top of the upright plates 21. The two upright plates 21 are vertical and relatively parallel, and are stably installed on the upper part of the machine body 1 through a positioning and fixing structure to ensure that the upright plates 21 do not tilt or shake during the pressing process. Each upright plate 21 has three round holes. Two horizontally arranged mounting round holes 211 are used to install the rotating shaft 34 of the driving roller 31 and the driven roller 32. A fixing round hole 212 located directly above the mounting round hole 211 is used to embed the outer ring 41 of the movable component 4. The inner wall of the top of the fixing round hole 212 has a fixing groove 213, which is adapted to the fixing block 411 on the outside of the outer ring 41. When the outer ring 41 is embedded in the fixing round hole 212, the fixing block 411 is embedded in the fixing groove 213 to form a circumferential limit, preventing the outer ring 41 from shifting with the rotation of the movable roller 33, and ensuring the stable operation of the movable component 4.

[0036] The cover plate 22 is connected to the top of the upright plate 21 via a detachable structure, facilitating subsequent opening and maintenance of the internal roller mechanism 3. A food-grade sealing gasket is provided at the connection between the cover plate 22 and the upright plate 21, effectively preventing sugarcane juice from overflowing through the gap, thus solving the cleaning problems and hygiene hazards caused by juice leakage in traditional equipment. An inclined feed inlet 221 is provided on one side of the cover plate 22, with its outlet facing the gap between the active roller 31 and the movable roller 33. The sugarcane's own weight can be used to assist feeding, guiding the sugarcane precisely into the roller mechanism 3, eliminating the need for repeated manual adjustments to the sugarcane's position and reducing operational difficulty. An inclined discharge chute 222 is provided on the other side of the cover plate 22, automatically guiding and discharging the pressed sugarcane residue, preventing waste residue from accumulating in the roller mechanism 3 and causing jamming, enabling continuous pressing operations and solving the problem of frequent shutdowns for waste residue cleaning required in traditional equipment.

[0037] The roller mechanism 3 is the core actuator for sugarcane pressing. It is located between two vertical plates 21 and includes a drive roller 31, a driven roller 32, and a movable roller 33. All three extend horizontally and have coaxial rotating shafts 34 integrally formed at both ends without welded joints, thus avoiding the risk of breakage during use. The rotating shafts 34 of the drive roller 31 and the driven roller 32 are respectively installed in the mounting holes 211 of the vertical plate 21 via bearings 35, ensuring smooth rotation and high coaxiality of the rotating shafts 34 and reducing radial runout during rotation. One end of the rotating shaft 34 of the drive roller 31 extends through the vertical plate 21 to the outside of the machine body 1 to connect to the drive assembly 5. The other end of the rotating shaft 34 of the driven roller 32 also extends to the outside of the machine body 1 to form synchronous transmission with the drive roller 31.

[0038] The movable roller 33 is located directly above the driving roller 31 and the driven roller 32, with their axes forming an isosceles triangle. This structure ensures that the sugarcane receives balanced pressure from three directions during pressing, reducing axial displacement caused by uneven force and ensuring that the sugarcane remains in the center of the roller's compression area. This maximizes the compression area, increases the juice extraction rate, and reduces the amount of juice residue in the sugarcane bagasse, solving the problems of uneven pressing force and low juicing efficiency in traditional equipment. The outer circumference of the movable roller 33 is covered with a rubber layer, and the outer surface of the rubber layer has spiral grooves. This increases the friction between the movable roller 33 and the sugarcane surface, preventing axial slippage of the sugarcane during pressing. The elasticity of the rubber layer also cushions and protects the sugarcane, preventing excessive crushing and the resulting excessive mixing of waste into the juice, thus ensuring the purity of the juice.

[0039] The movable component 4 is the core component for adjusting the roller spacing. It is used to install the rotating shaft 34 of the movable roller 33 and realize automatic spacing adjustment, directly solving the core problem of the fixed roller spacing of traditional presses and their inability to adapt to sugarcane of various diameters. It includes an outer ring 41, an inner ring 42, and multiple compression springs 43. The outer ring 41 is fixedly embedded in the fixing circular hole 212 of the upright plate 21. The inner sidewall is a regular polygonal structure, which is used to stabilize and fix the end of the compression spring 43 and prevent the compression spring 43 from shifting or falling off when it is under force. The inner ring 42 is sleeved on the rotating shaft 34 of the movable roller 33, forming a rotational fit with the rotating shaft 34 and being circumferentially fixed by a key connection, ensuring that the inner ring 42 rotates synchronously with the rotating shaft 34 and avoiding relative sliding and wear between the two.

[0040] Multiple compression springs 43 are evenly distributed along the circumference between the outer ring 41 and the inner ring 42, with their ends fixed to the inner wall of the outer ring 41 and the outer wall of the inner ring 42, respectively. When processing coarse sugarcane, the sugarcane squeezes the movable roller 33, pushing the inner ring 42 to compress the corresponding compression springs 43, increasing the distance between the movable roller 33 and the driving roller 31 and driven roller 32, ensuring that the coarse sugarcane passes smoothly and is effectively squeezed. When processing fine sugarcane, the compression springs 43 return to their original position, pushing the inner ring 42 and the movable roller 33 downwards, reducing the roller distance, and ensuring that the fine sugarcane is fully squeezed. The entire adjustment process requires no manual operation, achieving automatic adaptation to sugarcane of different diameters, greatly improving the equipment's versatility, and completely solving the problems of coarse sugarcane jamming and insufficient juice extraction of fine sugarcane in traditional equipment.

[0041] The drive assembly 5 provides stable power to the roller mechanism 3. It is mounted on the outside of the machine body 1 and is connected to the shaft 34 of the drive roller 31. It includes a drive motor 51, a reducer 52, a drive pulley 53, a synchronous pulley 54, and a driven pulley 55. The drive motor 51 is electrically connected to an external controller, which can adjust the motor's output speed to adapt to the pressing needs of sugarcane with different hardness and diameters. When pressing coarse, hard sugarcane, the speed is reduced to increase output torque and avoid motor overload; when pressing fine, soft sugarcane, the speed is increased to improve pressing efficiency, solving the problem of fixed speed in traditional equipment that cannot adapt to different sugarcane characteristics.

[0042] The reducer 52 is fixedly installed in the cavity at the bottom of the machine body 1. Its input end is connected to the output shaft of the drive motor 51, and its output end is fitted with a drive pulley 53. A synchronous pulley 54 is fixedly fitted onto the rotating shaft 34 extending from the drive roller 31 to the outside of the machine body 1. A driven pulley 55 is fixedly fitted onto the rotating shaft 34 extending from the driven roller 32 to the outside of the machine body 1. The synchronous pulley 54 and the driven pulley 55 are connected by a first belt 56, and the drive pulley 53 and the synchronous pulley 54 are connected by a second belt 57. During operation, the drive motor 51 drives the reducer 52. After being reduced in speed by the reducer, the drive pulley 53 drives the synchronous pulley 54 to rotate via the second belt 57. The synchronous pulley 54 drives the drive roller 31 to rotate, and simultaneously drives the driven pulley 55 and the driven roller 32 to rotate synchronously via the first belt 56. This ensures that the drive roller 31 and the driven roller 32 rotate at the same speed, preventing sugarcane wear or equipment vibration due to speed differences and extending the equipment's service life.

[0043] The sealing plate 6 is located inside the movable component 4 and is fixed to the inner wall of the upright plate 21 by bolts. Its diameter is larger than the diameter of the fixing hole 212 on the upright plate 21, completely covering the fixing hole 212. A circular through hole 61 is formed in the center of the sealing plate 6. The diameter of the through hole 61 is larger than the diameter of the rotating shaft 34 of the movable roller 33, and the rotating shaft 34 always moves within the range of the through hole 61 when the movable roller 33 moves up and down. The design of the sealing plate 6 effectively prevents sugarcane juice from overflowing from the gap between the fixing hole 212 and the rotating shaft 34, reducing residue residue inside the equipment, lowering cleaning difficulty, and solving the problems of internal component corrosion and hygiene hazards caused by juice leakage in traditional equipment.

[0044] Furthermore, the filter plate 12, which is slidably installed at the top opening 11 of the machine body 1, has a rectangular frame structure and is equipped with a filter screen inside. It can filter out coarse fiber residue in the sugarcane juice without the need for additional filtration steps, ensuring the purity of the juice. The filter plate 12 can be directly pulled out from the top of the machine body 1 for easy cleaning or replacement of the filter screen, making operation convenient. The inclined plate 13 below the filter plate 12 is fixed to the inner wall of the machine body 1 and is set at an angle, with the angle facing the center of the machine body 1. After pressing, the filtered juice falls onto the inclined plate 13 and collects along the inclined surface of the inclined plate 13 to the bottom center. The bottom center of the inclined plate 13 is connected to a curved pipe 14, and a pipe valve 15 is installed on the curved pipe 14. Opening the pipe valve 15 can realize the quantitative collection of juice, and closing the pipe valve 15 can stop the collection to change the container, avoiding juice spillage and waste.

[0045] The working process of this utility model is as follows:

[0046] Before the pressing operation, the operator first checks the equipment status: confirms that the compression spring 43 of the moving component 4 is not broken or deformed, the belt tension of the drive component 5 is appropriate, the pipe valve 15 is tightly closed, and the filter screen of the filter plate 12 is clean. Then, according to the diameter and hardness of the sugarcane to be pressed, the output speed of the drive motor 51 is set through the external controller.

[0047] After preparation, the drive motor 51 is started. The motor is reduced in speed by the reducer 52 and driven by the belt to rotate the active roller 31 and the driven roller 32 synchronously. The movable roller 33 is in a standby state. The operator holds the sugarcane and inserts one end of the sugarcane into the feed inlet 221 of the cover plate 22. Guided by the feed inlet 221, the sugarcane enters the squeezing area between the active roller 31 and the movable roller 33 precisely.

[0048] If the sugarcane diameter is large, the compression roller 33 deforms the compression spring 43, increasing the roller spacing, allowing the thick sugarcane to pass smoothly and be squeezed in three directions, squeezing out the juice. If the sugarcane diameter is small, the compression spring 43 returns to its original position, reducing the roller spacing, allowing the thin sugarcane to be fully pressed. The squeezed juice is filtered by the filter plate 12 and falls onto the inclined plate 13, converging along the inclined plate 13 to the curved pipe 14. Opening the pipe valve 15 allows the pure juice to be collected into a container. The pressed sugarcane residue is discharged from the discharge trough 222 and falls into a pre-set waste collection container.

[0049] After a batch of sugarcane is pressed, turn off the drive motor 51, remove the filter plate 12 to clean or replace the filter screen, and perform simple maintenance on the equipment regularly (such as checking the amount of lubricating oil in the reducer, the wear of the belt, and the tightness of the bolts) to ensure the long-term stable operation of the equipment.

[0050] This invention achieves automatic adjustment of roller spacing through movable components, fundamentally solving the problem that traditional presses cannot adapt to sugarcane of various diameters. At the same time, combined with a reasonable feeding, discharging, filtering and collection structure, it improves the ease of operation and the purity of juice, meeting the practical needs of small sugar workshops, fruit stalls and other scenarios.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
