Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically to a screening device for processing sliced ​​bamboo shoots. Background Technology

[0002] In the traditional process of slicing bamboo shoots, the screening stage faces numerous challenges. Previous screening equipment often used simple fixed screens or single-speed screening rollers, resulting in low screening efficiency. During screening, the bamboo shoots cannot be fully tumbled, making it difficult to accurately separate shoots of varying thicknesses. A large number of bamboo shoots that do not meet the requirements for slicing are mixed into the qualified products, increasing the workload of subsequent manual secondary screening and severely impacting production efficiency.

[0003] Meanwhile, traditional equipment lacks effective protection measures for the bamboo shoots during screening. The bamboo shoots come into direct contact and rub against the metal screening components, easily causing damage such as skin breakage and cracking. This not only reduces the quality of the bamboo shoots but also makes it difficult to guarantee the integrity and quality of the slices during subsequent slicing, affecting the product's market competitiveness. Utility Model Content

[0004] The purpose of this invention is to provide a screening device for processing sliced ​​bamboo shoots, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A screening device for processing sliced ​​bamboo shoots includes a feeding conveyor belt, a screening chamber is provided on the bottom surface of the feeding conveyor belt near one end, a power screening roller is rotatably connected to the inner wall of the screening chamber, and an auxiliary screening roller is provided on one side of the power screening roller.

[0007] A support frame is rotatably connected to the bottom surface of the screening chamber near one end, and a buffer spring is fixedly connected to the bottom surface of the screening chamber near the other end. The bottom end of the buffer spring is fixedly connected to the upper surface of the support frame, and a discharge conveyor belt is provided below the screening chamber.

[0008] A servo motor is fixedly connected to one end of the power screening roller, and a hydraulic push rod is rotatably connected to the outer wall of the screening chamber through a bearing seat. The bottom end of the hydraulic push rod is rotatably connected to the outer wall of the support base through a bearing seat.

[0009] A further improvement of the present invention is that: a screening baffle is attached to the inner wall of the screening chamber on one side, and mounting plates are fixedly connected to both ends of the screening baffle. The bottom end of the mounting plate is fixedly connected to the inner wall of the support frame, and a discharge guide inclined plate is provided below the screening baffle.

[0010] A further improvement of this utility model is that the two ends of the discharge guide inclined plate are fixedly connected to the inner wall of the mounting plate.

[0011] A further improvement of this utility model is that: one end of the power screening roller is fixedly connected to a pulley, and one end of the auxiliary screening roller is fixedly connected to a pulley.

[0012] A further improvement of this utility model is that the first pulley is connected to the second pulley via a belt, and the diameter of the second pulley is larger than that of the first pulley.

[0013] A further improvement of this utility model is that: the outer walls of the power screening roller near both ends are rotatably connected to mounting bases.

[0014] A further improvement of this utility model is that a soft rubber layer is fixedly connected to the outer wall of the power screening roller.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] This invention provides a screening device for processing sliced ​​bamboo shoots. By using different rotation speeds of the powered screening roller and the auxiliary screening roller, the bamboo shoots are fully tumbled during the screening process, enabling precise screening of bamboo shoots that do not meet the thickness requirements. Simultaneously, the use of a discharge guide inclined plate and an adjustable-angle screening bin facilitates the sliding of thicker bamboo shoots into the non-conforming product collection area, greatly improving the efficiency of screening and discharge.

[0017] This invention provides a screening device for processing sliced ​​bamboo shoots. The soft rubber layer covering the surfaces of the power screening roller and the auxiliary screening roller effectively avoids damage to the bamboo shoots during the screening process, ensuring the integrity and quality of the bamboo shoots and providing high-quality raw materials for subsequent slicing.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-4 As shown, this utility model provides a screening device for processing sliced ​​bamboo shoots, including a feeding conveyor belt 1, a screening chamber 2 is provided on the bottom surface of the feeding conveyor belt 1 near one end, a power screening roller 3 is rotatably connected to the inner wall of the screening chamber 2, and an auxiliary screening roller 4 is provided on one side of the power screening roller 3.

[0027] A support frame 7 is rotatably connected to the bottom surface of the screening chamber 2 near one end, and a buffer spring 10 is fixedly connected to the bottom surface of the screening chamber 2 near the other end. The bottom end of the buffer spring 10 is fixedly connected to the upper surface of the support frame 7. A discharge conveyor belt 6 is provided below the screening chamber 2.

[0028] A servo motor 5 is fixedly connected to one end of the power screening roller 3. A hydraulic push rod 11 is rotatably connected to the outer wall of the screening chamber 2 via a bearing seat. The bottom end of the hydraulic push rod 11 is rotatably connected to the outer wall of the support base 7 via a bearing seat. The servo motor 5 is an AC servo motor with a power of 1.5-2 kW, featuring high precision and high response speed, capable of stably driving the power screening roller 3. Both pulley 8 and pulley 9 are made of aluminum alloy with a special surface treatment to increase the friction between the belt and the pulley. The belt is a high-strength rubber synchronous belt with a width of 5-8 cm and a tooth pitch of 8-10 mm to ensure no slippage during transmission. A belt tensioning device is also installed near the pulleys to adjust the belt tension at any time, ensuring transmission stability.

[0029] The rotational speed of the power screening roller 3 can be adjusted between 15-40 revolutions per minute via the controller of the servo motor 5. The rotational speed of the auxiliary screening roller 4 changes accordingly based on the transmission ratio of the belt pulley, which is set between 1.2 and 1.5 to ensure that the bamboo shoot strips tumble fully during the screening process. The spacing between the screening rollers can be adjusted by pushing the screening chamber 2 with the hydraulic push rod 11, thereby achieving flexible adjustment from 0.5 to 3 centimeters to meet the screening requirements of bamboo shoot strips of different thicknesses. The conveying speed of the bamboo shoot strips on the feed conveyor belt 1 can be controlled by a speed-regulating motor, ranging from 0.5 to 1.5 meters per minute. The screening time can be set between 5 and 15 seconds depending on the actual condition of the bamboo shoot strips.

[0030] Example 2

[0031] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a screening baffle 12 is attached to the inner wall of the screening chamber 2 near one side, and mounting plates are fixedly connected to both ends of the screening baffle 12. The bottom end of the mounting plate is fixedly connected to the inner wall of the support frame 7, and a discharge guide inclined plate 13 is provided below the screening baffle 12.

[0032] The two ends of the discharge guide inclined plate 13 are fixedly connected to the inner wall of the mounting plate.

[0033] One end of the power screening roller 3 is fixedly connected to a pulley 8, and one end of the auxiliary screening roller 4 is fixedly connected to a pulley 9.

[0034] Belt pulley 8 is connected to belt pulley 9 via belt, and the diameter of belt pulley 9 is larger than that of belt pulley 8.

[0035] Mounting bases 15 are rotatably connected to the outer walls of the power screening roller 3 near both ends, and a soft rubber layer 14 is fixedly connected to the outer wall of the power screening roller 3.

[0036] The working principle of the screening equipment used for processing sliced ​​bamboo shoots will be explained in detail below.

[0037] like Figure 1-4 As shown, the bamboo shoot strips enter the screening chamber 2 from the feed conveyor belt 1. Under the combined action of gravity and the friction of the powered screening roller 3, the bamboo shoot strips are sandwiched between the powered screening roller 3 and the auxiliary screening roller 4. When the powered screening roller 3 is driven to rotate by the servo motor 5, it drives the auxiliary screening roller 4 to rotate via a belt. The different rotation speeds of the three powered screening rollers and the auxiliary screening roller 4 cause the bamboo shoot strips to tumble continuously during the screening process. During this process, bamboo shoot strips with a diameter larger than the spacing between the screening rollers are blocked and cannot pass through the screening area. The blocked, thicker bamboo shoot strips are pushed to the position of the discharge guide inclined plate 13 as the screening rollers rotate, and then slide down into the non-conforming product collection area after entering the discharge guide inclined plate 13.

[0038] When discharging thicker bamboo shoots, the hydraulic push rod 11 can be activated to pull the screening chamber 2 to deflect at an angle. The screening plane formed by the power screening roller 3 and the auxiliary screening roller 4 will then tilt towards the position of the discharge guide plate 13, which facilitates the discharge of thicker bamboo shoots.

[0039] Both the power screening roller 3 and the auxiliary screening roller 4 are tightly wrapped with a soft rubber layer 14 about 5 mm thick to protect the bamboo shoot strips.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
