Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of feeding device and sugarcane juice extraction equipment. BACKGROUND

[0002] Sugarcane juice extraction equipment is widely used in juice extraction process, and the prior art sugarcane juice extraction equipment usually includes a feeding device and a juicing device. The feeding device is mainly used to store a large number of substantially identical specification sugarcane rods and transport them to the juicing device at appropriate times. The juicing device receives the sugarcane rods output from the feeding device and processes them to obtain sugarcane juice.

[0003] In the prior art, the feeding device generally adopts a box structure for storing multiple sugarcane rods. However, this design has certain limitations, i.e., it is difficult to accurately control the number of sugarcane rods output each time during the process of outputting the sugarcane rods from the feeding device to the juicing device.

[0004] Under normal circumstances, the box design cannot guarantee the output of only one sugarcane rod at a time. If multiple sugarcane rods are sent out at the same time, it will cause the feeding port to be blocked, which may cause the equipment to jam / stall, thereby affecting the continuous working efficiency of the juicing equipment and possibly adversely affecting the service life of the equipment. SUMMARY

[0005] The first purpose of the utility model is to provide a feeding device with smooth material conveying.

[0006] The second purpose of the utility model is to provide a sugarcane juice extraction equipment with smooth sugarcane rod conveying and correction function.

[0007] The first purpose of the utility model is achieved as follows:

[0008] A feeding device includes a conveyor belt device for carrying materials, a box for storing materials, and a lifting door device,

[0009] The box is an open-bottomed box, one side wall of the box is provided with a discharge port near the open port position, the box is located above the conveyor belt device, the open port of the box faces the conveyor belt device, and the transportation direction of the conveyor belt device faces the discharge port;

[0010] The lifting door device is arranged above the conveyor belt device and in front of the discharge port, and a through port with variable size is formed between the lifting door device and the conveyor belt device;

[0011] When the size of the through port is greater than the size of the material, the conveyor belt device carries the material to move outward along the discharge port and the through port;

[0012] When the size of the through port is smaller than the size of the material, the through port hinders the movement of the material.

[0013] Since the size of the pass-through opening between the lifting door device and the conveyor belt device can be adjusted, the size of the material output each time can be effectively controlled. When the size of the pass-through opening is larger than the size of the material, the material can pass through smoothly and be discharged along the conveyor belt; and when the size of the pass-through opening is smaller than the size of the material, the lifting door device can effectively hinder the movement of the material, thereby ensuring that the amount of material output each time is controllable, and the problem of multiple materials being output at the same time is avoided.

[0014] The feeding device can ensure that the materials are output in sequence and one by one, and is especially suitable for occasions where the amount of material needs to be accurately controlled. For example, in a sugarcane juice extraction device, the device can accurately control the output of sugarcane rods, avoiding the phenomenon of sugarcane accumulation or jamming, and improving the operating efficiency of the device.

[0015] The feeding device of the present application can adapt to materials of different sizes and shapes, and only needs to adjust the opening size of the lifting door device according to the size of the material. Therefore, it has high universality and can be widely applied to the conveying and processing of different materials.

[0016] By accurately controlling the output of the material, the burden on the device caused by excessive or insufficient output of the material is avoided, the jamming and wear of the device are reduced, and the service life of the device is prolonged.

[0017] The structure of the device is simple and concise, the operation of adjusting the size of the pass-through opening is convenient and fast, and the size of the pass-through opening can be adjusted in real time according to needs, which not only improves the automation level of the device, but also reduces the need for manual intervention and saves labor costs.

[0018] The first purpose of the present application can also be solved by the following technical measures:

[0019] Further, the lifting door device comprises a supporting frame, a door body and a spring, the supporting frame is arranged on both sides of the conveyor belt device respectively, the door body is arranged between the supporting frames in a movable manner and located between the conveyor belt devices, the pass-through opening is formed between the door body and the conveyor belt device, one end of the spring is connected to the supporting frame, and the other end of the spring is connected to the door body, and the spring constitutes a reset mechanism of the door body.

[0020] When the conveyor belt moves with the material and touches the door body, the material pushes the door body up by overcoming the elastic force of the spring, thereby adjusting the size of the pass-through opening. This design enables the pass-through opening to be automatically adjusted according to the size of the material and the conveying needs, ensuring that the material passes through smoothly and avoiding the situation of jamming or accumulation of the material due to size mismatch or excessive conveying resistance. This process does not require manual intervention, greatly improving the automation and convenience of operation.

[0021] Through the dynamic adjustment of the pass-through opening, the downtime caused by material jamming or congestion is effectively reduced, ensuring smooth material conveying. After the material passes through the opening, the spring force automatically restores the door body to the initial position, maintaining the stability of the system. This self-recovery function makes the entire material conveying process more efficient and stable, improving the operating efficiency of the equipment.

[0022] The spring acts as a natural reset mechanism, eliminating the need for additional power or pneumatic system support for the door body lifting, thereby saving energy consumption and equipment costs. This design not only makes the system more concise, but also reduces operation and maintenance costs, enhancing the economy of the equipment.

[0023] As the types, shapes, and sizes of materials change, the pass-through opening between the conveyor belt and the door body can be automatically adjusted according to actual needs, ensuring that the system can adapt to different material types. This high degree of adaptability allows the feeder to be widely used in various types of material handling, increasing the versatility and scope of the system.

[0024] Since the material can automatically adjust the size of the pass-through opening after touching the door body, manual adjustment is not required, improving the ease of operation. In addition, the door body moves smoothly under the action of the spring during adjustment, avoiding injury to the system or personnel due to improper or sudden changes, enhancing the safety of the system.

[0025] Further, the head of the door body faces the conveyor belt device, and the head of the door body facing the inlet port side wall is an arc-shaped guide side wall. When the material moves in the direction of the pass-through opening, the material touches the arc-shaped guide side wall, and the material pushes the door body up to adjust the size of the pass-through opening by overcoming the spring force.

[0026] When the material moves in the direction of the pass-through opening, it will first touch the arc-shaped guide side wall. Through the curved shape of the side wall, the material can more smoothly contact the door body and push the door body up. Compared to a straight or acute angle door body design, the arc-shaped side wall can reduce friction and impact between the material and the door body, making the material pass more smoothly and preventing jamming or irregular motion.

[0027] The arc-shaped guide side wall provides a more gradual contact surface, allowing the material to distribute the force more evenly when pushing the door body up. In this way, the material can better overcome the spring force after touching the door body, pushing the door body up accurately and stably to adjust the size of the pass-through opening. This design reduces collisions between the material and the door body, improving the accuracy and efficiency of material passing.

[0028] As the material touches more evenly, the force of the spring can be better distributed over a larger surface area, avoiding uneven lifting caused by concentrated force, further improving the stability and reliability of the door body lifting. This allows the spring to adjust the passage size more smoothly, ensuring smooth passage of the material each time.

[0029] Arc-shaped guiding design can effectively adapt to different shapes and sizes of materials, especially suitable for those that may have irregular shapes. During processing, the way materials contact with arc-shaped guiding side walls can automatically adapt to different positions and forms of materials, thereby improving the adaptability and stability of the system to different types of materials.

[0030] The design of arc-shaped guiding side walls not only helps the smooth delivery of materials, but also reduces direct friction between the door body and the material. As the material contacts the door body more gently, the wear of the equipment is reduced, thereby prolonging the service life of the equipment. Reducing friction and impact can also reduce noise and vibration during the lifting of the door body, improving the smoothness of the system operation.

[0031] Arc-shaped guiding side walls ensure that materials can smoothly push the door body and effectively adjust the size of the passage, making the delivery of materials more accurate. When the material leaves the passage, the spring force automatically restores the door body to the initial position, ensuring that the door body can quickly and accurately return to the original state for the next material delivery.

[0032] Further, the head of the door body is a V-shaped head.

[0033] Further, the door body is a stainless steel door body.

[0034] Further, it also includes an elastic baffle, which is arranged between the discharge port and the passage, and the elastic baffle extends towards the direction of the conveyor belt device.

[0035] The elastic baffle can automatically correct the placement position of the material during its movement. When the material enters the passage in the correct placement position, different parts of the material will simultaneously contact the corresponding elastic baffle, thereby maintaining the stable flow of the material. If the material is not placed correctly and some positions do not contact the baffle, the elastic baffle will automatically correct it as the material continues to move, ensuring that the material passes along the predetermined path smoothly. This design makes the material processing more automated, reducing the need for manual intervention.

[0036] The elastic baffle can provide appropriate guidance during the delivery of the material, ensuring that the material is always in the correct direction. This is particularly important for applications that require precise control of material flow. It avoids jamming or deviation from the delivery path due to improper placement of the material, ensuring smooth and efficient delivery.

[0037] The elastic baffle design enables the system to automatically adapt to different shapes and sizes of materials. Regardless of the initial placement position of the materials, the elastic baffle helps the materials to self-adjust to the optimal position, ensuring that the materials can smoothly enter through the port. This self-adaptive ability enables the feeding device to handle multiple types of materials, increasing the versatility and flexibility of the system.

[0038] The introduction of the elastic baffle not only improves the accuracy of material placement, but also reduces the probability of jamming or equipment failure caused by incorrect material placement. It can reduce equipment downtime and maintenance costs caused by material problems, and improve the stability and reliability of the equipment.

[0039] Since the elastic baffle has the function of automatically correcting the placement of materials, the operator does not need to intervene too much in the placement position of the materials, which is particularly important in high-efficiency production lines or automated environments. The materials can self-adjust during the conveying process, reducing the need for operators to monitor the position of the materials, improving the simplicity and efficiency of the operation.

[0040] The elastic baffle can ensure that the materials are stable and not inclined during the conveying process, thereby reducing the collision and loss of materials caused by improper placement. Especially when handling fragile or special-shaped materials, it can reduce the breakage rate of materials and ensure the integrity of the materials.

[0041] Further, a crossbeam is also included, which is connected to the support frame and located between the discharge port and the through port. The crossbeam is spaced apart from the elastic baffle, with the upper end of the elastic baffle connected to the crossbeam and the lower end of the elastic baffle facing the direction of the conveyor belt device.

[0042] Further, the gap between the elastic baffle and the conveyor belt device forms a correction gap, which is smaller than the size of the material.

[0043] Since the correction gap is smaller than the size of the material, when the material passes through the correction gap, the material will inevitably push the elastic baffle to deform. This process can effectively automatically correct the placement position of the material, ensuring that the material is always in the correct position, avoiding jamming or misplacement caused by improper material position.

[0044] The deformation process of the elastic baffle enables the material to move accurately along the conveying path, avoiding the deviation, inclination or accumulation of the material. Especially for irregular-shaped or long materials, the correction gap can effectively guide the material to maintain the correct direction, improving the accuracy during the conveying process.

[0045] Due to the flexible baffle, flexible guidance can be provided when the material passes, reducing direct friction between the material and the conveying belt or other components, and reducing the risk of material damage.

[0046] By automatically adjusting the material position through the correction gap, the operator does not need to manually intervene in the placement or adjustment of the material, greatly simplifying the material processing process and improving the automation level and efficiency of the system.

[0047] This design ensures that the material always maintains the correct position during the next stage of conveying or processing, avoiding blockage caused by misalignment or accumulation of the material, and improving the smoothness of the material flow.

[0048] Further, the conveying belt device comprises a driving assembly, a conveying belt, a first roller, a second roller and a transmission rod, the first roller and the second roller are sleeved on the transmission rod, the first roller and the second roller rotate with the transmission rod, the conveying belt is tensioned on the first roller and the second roller respectively, the driving assembly is connected with the transmission rod, and the driving assembly drives the corresponding conveying belt to move through the transmission rod, the first roller and the second roller.

[0049] Due to the arrangement of two conveying belts, the resistance of a single conveying belt due to excessive load or local friction is avoided.

[0050] The reduction of friction directly leads to the improvement of system energy efficiency, and the driving assembly consumes relatively less energy when driving the two conveying belts, which helps to reduce the overall energy consumption of the equipment.

[0051] The design of two conveying belts can make the load evenly distributed, avoiding excessive wear of a single conveying belt due to excessive tension or uneven load.

[0052] The purpose of the utility model is achieved as follows:

[0053] A sugarcane juice extraction device comprises a feeding device for storing and conveying sugarcane rods.

[0054] The feeding device can realize automatic storage and precise conveying of sugarcane stalks, ensuring smooth flow of sugarcane stalks during the juicing process. Through the reasonable design of the conveying belt and the lifting door device, the material (sugarcane stalks) can be stably conveyed to the juicing device, improving the efficiency and automation level of the entire juicing process.

[0055] By setting the elastic baffle, the placement position of the sugarcane stalks can be automatically corrected during the material conveying process, ensuring that the material always maintains the correct position during the conveying process, avoiding the jamming or unsmooth conveying of sugarcane stalks due to improper placement. This design significantly improves the intelligent level of the conveying process and reduces the need for manual intervention.

[0056] By using two conveying belts, the friction is reduced, thereby improving the operating efficiency and energy efficiency of the system. The double conveying belt design not only reduces energy consumption, but also effectively balances the load, reduces equipment wear and tear, and prolongs the service life of the equipment.

[0057] The feeding device can adapt to different sizes and shapes of sugarcane stalks through precise control and adjustment, and even in some different production environments, it can adapt to the processing needs of other materials. This highly adaptable design makes the device have a wider application prospect.

Ultimately, it improves the juicing efficiency, maximizes the extraction rate of juice, and improves the quality of the final product.

[0059] The beneficial effects of the utility model are as follows:

[0060] The utility model, through setting correction gap and elastic baffle, material can automatically adjust placement position during conveying process.

This design greatly reduces manual intervention, improves the automation level and conveying efficiency of the equipment.

[0061] The utility model, lifting door device combines arc-shaped guide side wall and spring return mechanism, can accurately adjust the size of the pass-through port, ensuring smooth passage of material. When sugarcane stalks touch the guide side wall, the door body will be pushed up to adjust the size of the pass-through port to adapt to sugarcane stalks of different sizes. After the material passes through, the door body will automatically reset to maintain normal operation of the equipment, avoiding the phenomenon of material jamming or uneven conveying.

[0062] The utility model discloses, double conveyer belt design and gyro wheel transmission system effectively reduced the friction between material and conveyer belt, ensure that the cane rod can smoothly, stably pass through conveyer belt device.
