Description

Technical Field

[0001] This utility model relates to the technical field of oil crushing equipment, specifically to a roller tensioning device for an oil crusher. Background Technology

[0002] The oilseed double-roll crusher is a mechanical crushing equipment specifically designed for the pre-processing stage of oil crops such as soybeans, rapeseed, cottonseed, and peanuts. Its core function is to compress the material through two relatively rotating rollers, thereby reducing the particle size and breaking down the structure of the oilseeds, providing suitable material conditions for subsequent pressing or leaching oil extraction processes. However, existing double-roll oilseed crushers cannot avoid damage caused by impurities such as gravel and iron blocks mixed inside the oilseed particles. After crushing stones and small iron blocks, the two crushing rollers cannot automatically shift. Even if they can shift to increase the compression space for self-protection, the drive belt becomes loose after displacement and cannot achieve proper tension, preventing the double rollers from consistently operating normally. This is detrimental to stable operation and prone to failure and damage due to repeated momentary loss of driving force. Therefore, a roller tensioning device for the oilseed crusher is needed to solve these problems. Utility Model Content

[0005] Both the first drive control body and the second drive control body include a synchronous drive rod, a first drive wheel, a limiting rotary clamp end, a drive belt, a first tension adjustment part, a squeeze roller, a second tension adjustment part, a fixed mounting plate, a motor, and a second drive wheel. The first tension adjustment part and the second tension adjustment part are distributed at both ends of the squeeze roller.

The synchronous drive rod is fixedly installed between the middle of the first drive wheel and the second drive wheel. The motor is fixedly installed on the fixed mounting plate, and the drive end of the motor is fixedly connected to the middle of the outer end of the second drive wheel. The drive belt is rotatably disposed between the first drive wheel and the first tension adjustment part and the second drive wheel and the second tension adjustment part.

[0006] Preferably, the self-adjusting body includes a tensioning limit wheel, a detection support plate, an electric push rod, and a second fixed mounting plate. The electric push rod is fixedly installed in the middle of the upper end of the second fixed mounting plate. The detection support plate is fixedly installed in the bottom end of the tensioning limit wheel by bolts. The upper end of the electric push rod is fixedly connected to the middle of the bottom end of the detection support plate.

[0007] Preferably, the first tension adjustment part and the second tension adjustment part have the same structure. Both the first tension adjustment part and the second tension adjustment part include a movable support base, a first drive limit rod, a second drive limit rod, a synchronous drive wheel, a limit fixing base, a first fixed mounting plate, a protective reset spring, a fixed mounting plate, and a detection plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] I. This utility model addresses the issue of impurities such as gravel and metal particles passing between the two extrusion rollers. The hard particles cause the extrusion rollers to compress the protective reset spring, which then slides along the limiting base, increasing the extrusion gap between the two rollers. This automatically protects the rollers from damage caused by foreign objects. A pressure sensor is installed at one end of the protective reset spring connected to the movable support. When the movable support compresses the protective reset spring, the pressure sensor detects the corresponding pressure value, providing pressure data for subsequent control. A first laser is symmetrically fixedly installed on the inner side of the bottom of the movable support. The distance sensor, with the detection plate located directly in front of it, can accurately detect the change in the distance between the moving support and the detection plate, and monitor the moving distance of the extrusion roller in real time. Based on the information data detected by the pressure sensor and the first laser distance sensor, and after comparing it with the preset parameter values, the external control device can automatically control the operation of the electric push rod at the corresponding position. The electric push rod drives the detection support plate and the tension limit wheel to move downwards accurately and quickly a specified distance, so that the drive belt after the tension limit wheel is pulled loose can be adjusted to tension, ensuring that the drive belt is always taut during the movement and self-holding process of the two extrusion rollers, achieving stable drive and avoiding the situation of instantaneous loss of drive.

[0015] II. During the process of the electric push rod driving the detection support plate and tension limit wheel to pull the drive belt downward, the second laser ranging sensor can accurately detect the amount of movement of the detection support plate and tension limit wheel, ensuring that the tension of the drive belt pulled downward by the tension limit wheel and detection support plate matches the information detected by the pressure sensor and the first laser ranging sensor. No matter how far the two extrusion rollers move to achieve self-holding, the drive belt can receive the corresponding degree of tension adjustment. Attached Figure Description

[0025] Please see Figure 5 The self-adjusting main body 3 includes a tensioning limit wheel 25, a detection support plate 26, an electric push rod 27, and a second fixed mounting plate 28.

The detection support plate 26 is fixedly installed in the bottom end of the tensioning limit wheel 25 by bolts. The upper end of the electric push rod 27 is fixedly connected to the middle of the bottom end of the detection support plate 26.

[0026] Please see Figure 2-4 The first tension adjustment part 8 and the second tension adjustment part 10 have the same structure. Both the first tension adjustment part 8 and the second tension adjustment part 10 include a movable support base 14, a first drive limit rod 15, a second drive limit rod 16, a synchronous drive wheel 17, a limit fixing base 18, a first fixed mounting plate 19, a protective return spring 21, a fixed mounting plate 22, and a detection plate 23. The first fixed mounting plate 19 is fixedly installed on both sides of the bottom end of the limit fixing base 18. The detection plate 23 is fixedly installed on the outer end of the limit fixing base 18 by bolts. The protective return springs 21 are symmetrically distributed on both sides of the bottom of the movable support base 14 and fixedly installed between the fixed mounting plates 22. The protective return springs 21 are distributed at both ends of the fixed mounting plate 22. The fixed mounting plate 22 is fixedly installed on the upper part of the limit fixed base 18 near the detection plate 23 and the outer side of the bottom end of the movable support base 14 by bolts. The first drive limit rod 15 is rotatably engaged with the upper end of the movable support base 14. The synchronous drive wheel 17 is fixedly connected to the side end of the first drive limit rod 15 away from the movable support base 14. The second drive limit rod 16 is fixedly connected to the middle of the side end of the synchronous drive wheel 17 away from the first drive limit rod 15. The protective reset spring 21 plays the role of compression buffer protection and reset. Furthermore, the first drive limit rod 15, the second drive limit rod 16 and the first fixed mounting plate 19 can make it easy to limit or fix the workpiece components in this device to the outer frame of the crusher.

[0027] The bottom inner side of the movable support base 14 is symmetrically fixed with a first laser range sensor 24, and the detection plate 23 is located in front of the first laser range sensor 24, which can accurately detect the moving distance and realize accurate and fast real-time detection.

[0028] The protective reset spring 21 is connected to one end of the movable support base 14, and a pressure sensor 20 is fixedly installed between the fixed mounting plate 22 and the movable support base 14 to detect pressure. The sensor analyzes the detection data through an externally set controller to help determine the distance of movement.

[0029] The second drive limit rod 16 is fixedly connected to the middle of the end of the extrusion roller 9.

[0030] The drive belt 7 is respectively positioned between the first drive wheel 5 and the second drive wheel 13 and the synchronous drive wheels 17 positioned at both ends of the extrusion roller 9, and serves as a drive.

[0031] The tension limit wheel 25 is located in the middle of the drive belt 7. The rotating part of the tension limit wheel 25 is located in the middle of the drive belt 7, and plays the role of tension adjustment.

[0032] When the first laser rangefinder 24 detects that the displacement of the movable support 14 exceeds the set threshold and the pressure sensor 20 detects an abnormal pressure, the signal is transmitted to the external controller. The controller calculates the required extension and retraction of the electric push rod 27 according to the preset algorithm and drives the electric push rod 27 to make a rapid movement. The second laser rangefinder 29 provides real-time feedback on the position of the tension limit wheel 25, forming a closed-loop control to ensure tension accuracy.

[0033] Working principle: During operation, the motors 12 in the first drive control body 1 and the second drive control body 2 run synchronously, driving the second drive wheel 13. The synchronous drive rod 4 enables the second drive wheel 13 and the first drive wheel 5 to rotate synchronously. The drive belt 7 and the synchronous drive wheel 17 enable the extrusion rollers 9 in the first drive control body 1 and the second drive control body 2 to rotate synchronously and at the same speed in the specified direction. This causes the particles conveyed between the two extrusion rollers 9 to be crushed. When impurities such as gravel and metal particles pass between the two extrusion rollers 9, the hard impurities... When the particles pass between the extrusion rollers 9, the extrusion rollers 9 in the first drive control body 1 and the second drive control body 2 drive the second drive limit rod 16, the synchronous drive wheel 17, and the first drive limit rod 15, ultimately causing the movable support seat 14 to compress the protective reset spring 21 and slide along the limit fixing base 18. This increases the extrusion gap between the two extrusion rollers 9, thereby achieving automatic protection for the two extrusion rollers 9. When the movable support seat 14 compresses the protective reset spring 21 and slides along the limit fixing base 18, the pressure sensor 20 can detect the corresponding pressure value, and the two first laser ranging sensors are set up. Sensor 24 can accurately detect changes in the distance between itself and the detection plate 23. Based on the detected data and pre-set parameter values ​​after repeated testing, the external control device can automatically control the electric push rod 27 at the corresponding position. The electric push rod 27 can drive the detection support plate 26 and the tension limit wheel 25 to move downwards precisely and quickly by a specified distance. This allows the tension limit wheel 25 to pull the relaxed drive belt 7 to adjust its tension, ensuring that the drive belt 7 remains taut and stable during the self-positioning movement of the two extrusion rollers 9. This ensures that the two extrusion rollers 9 move smoothly and efficiently. During normal rotation, there will be no momentary loss of drive. Furthermore, as the electric push rod 27 drives the detection support plate 26 and tension limit wheel 25 to pull the drive belt 7 downward, the second laser range sensor 29 can accurately detect the amount of movement of the detection support plate 26 and tension limit wheel 25. This ensures that the degree of tension of the drive belt 7 as the tension limit wheel 25 and detection support plate 26 move downward matches the information detected by the pressure sensor 20 and the first laser range sensor 24, ensuring that the drive belt 7 can always be adjusted to the corresponding degree of tension regardless of how far the two extrusion rollers 9 move to achieve self-holding.
