Description

Technical Field

[0001] This utility model relates to the field of peeling machine technology, specifically to a constant pressure tensioning mechanism for peeling rollers. Background Technology

[0002] Tensioning the peeling rollers is a crucial step in the assembly of a peeling machine. A reasonable and reliable tension directly affects the peeling efficiency and the lifespan of key components. Traditional corn harvesting machinery commonly employs mechanical spring-type or screw-adjustable peeling roller tensioning mechanisms in the ear-processing stage. The spring is fitted onto a screw, with one end contacting a rocker arm and the other end contacting an adjusting nut on the screw. The tension of the spring is adjusted by the adjusting nut. This type of structure has revealed technical limitations in practical applications, specifically: 1. As working time increases, the adjusting nut is prone to loosening, and the spring tension is also prone to fatigue decay, which eventually leads to instability of the peeling roller tension.

[0003] 2. When adjusting the tension of a traditional tensioning mechanism, the tensioning mechanism of each set of peeling rollers must be adjusted. It is difficult to ensure the consistency of tension among multiple sets of peeling rollers, and the adjustment is inconvenient. Utility Model Content

[0004] To solve at least one of the above technical problems, this utility model provides a constant pressure tensioning mechanism for peeling rollers.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: This utility model provides a constant pressure tensioning mechanism for a peeling roller, including a peeling roller frame, a first swing arm, and a second swing arm. The first swing arm and the second swing arm are arranged opposite to each other and spaced apart. The middle parts of both the first and second swing arms are connected to the peeling roller frame, and at least one of the first and second swing arms is hinged to the peeling roller frame. A telescopic cylinder is provided at the lower end of the first swing arm, and an elastic element is provided at the telescopic end of the telescopic cylinder. The elastic element is connected to the lower end of the second swing arm. The upper ends of both the first and second swing arms are used to install the peeling roller.

[0006] The beneficial effects of this utility model are: This invention utilizes a telescopic cylinder to apply pressure to the first and second swing arms, causing them to swing in opposite directions. This achieves tension between the peeling moving roller and the peeling stationary roller at the upper ends of the first and second swing arms. By controlling the constant pressure of the telescopic cylinder, the tension between the peeling moving roller and the peeling stationary roller can be kept constant, avoiding tension fatigue and improving the reliability of the peeling roller. Furthermore, a single pressure system can simultaneously control the telescopic cylinders of multiple peeling rollers, eliminating the need to adjust each set of peeling rollers individually when adjusting the tension, thus improving convenience and efficiency, and enhancing the consistency of tension across multiple sets of peeling rollers. In addition, the pressure between the telescopic cylinder and the second swing arm is transmitted through an elastic element, which helps to buffer vibrations during operation of the peeling roller, preventing mechanical damage and extending the service life of the device.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the fixed end of the telescopic cylinder is hinged to the first swing arm, and the telescopic end of the telescopic cylinder is fixedly connected to the elastic element.

[0009] By rotating the telescopic cylinder relative to the first swing arm, the amplitude of the relative swing between the first and second swing arms is compensated, reducing the deflection of the elastic element, avoiding fatigue of the elastic element, and extending the service life of the elastic element.

[0010] Furthermore, the telescopic cylinder has a guide rod fixed to its telescopic end, and the end of the guide rod away from the telescopic cylinder moves through the second swing arm; the elastic element is a spring, which is sleeved on the guide rod, and the end of the elastic element away from the telescopic cylinder abuts against the second swing arm.

[0011] The elastic element is supported by the guide rod, while the second swing arm can restrain the excessive movement of the guide rod, thus avoiding the deflection instability of the elastic element and improving the stability of the pressure applied by the telescopic cylinder to the second swing arm.

[0012] Furthermore, the guide rod is coaxially arranged with the telescopic end of the telescopic cylinder, and a limiting component is fixedly sleeved on the telescopic end of the telescopic cylinder. One end of the elastic element abuts against the limiting component, and the other end of the elastic element abuts against the second swing arm.

[0013] This improves the stability of the elastic element.

[0014] Furthermore, the limiting component is a nut, and the limiting component is threadedly connected to the telescopic end of the telescopic cylinder.

[0015] It is easy to adjust the position of the limiting component, thereby adapting to the length or fatigue level of the elastic element, and has good flexibility.

[0016] Furthermore, the telescopic cylinder has a pressure channel and an internal threaded connector on its side. The internal threaded connector is connected to the pressure channel, and the pressure channel is connected to the cylinder body of the telescopic cylinder. The internal threaded connector is fixed to the outer wall of the cylinder body of the telescopic cylinder.

[0017] It is easy to connect to external pressure pipelines and is convenient to install.

[0018] Furthermore, the middle parts of both the first and second swing arms are hinged to the peeling roller frame.

[0019] The upper ends of both the first and second swing arms are used to install peeling moving rollers. Two peeling fixed rollers are added between the two peeling moving rollers. The peeling fixed rollers are installed on the peeling roller frame, thus installing two pairs of peeling rollers, resulting in a compact structure.

[0020] Furthermore, there are multiple and equal numbers of the first and second swing arms. The first and second swing arms are arranged alternately from one end of the peeling roller frame to the other end. A telescopic cylinder and an elastic element are provided between the nth first swing arm and the nth second swing arm, where n is a positive integer.

[0021] It is easy to install multiple peeling rollers on the same peeling roller frame, and the structure is compact.

[0022] Furthermore, it also includes a pressure supply component, which is connected to a pressure supply pipeline, and the pressure supply pipeline is connected to each telescopic cylinder through branch lines.

[0023] By controlling the output pressure of the pressure supply component, the tension of each set of peeling moving rollers and peeling stationary rollers can be controlled simultaneously, resulting in high adjustment efficiency and good tension consistency.

[0024] Furthermore, the telescopic cylinder is a hydraulic telescopic cylinder, and the pressure supply component is a hydraulic pump.

[0025] It is easy to control hydraulically, has good pressure stability, and is highly safe. Attached Figure Description

Detailed Implementation

[0030] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0031] This utility model refers to Figure 1-3 .

[0032] This utility model provides a constant pressure tensioning mechanism for peeling rollers, including a peeling roller frame 1, a first swing arm 2, and a second swing arm 3. The first swing arm 2 and the second swing arm 3 are arranged opposite to each other and spaced apart. The middle parts of the first swing arm 2 and the second swing arm 3 are both connected to the peeling roller frame 1, and at least one of the first swing arm 2 and the second swing arm 3 is hinged to the peeling roller frame 1. The lower end of the first swing arm 2 is provided with a telescopic cylinder 4, and the telescopic end of the telescopic cylinder 4 is provided with an elastic element 5, which is connected to the lower end of the second swing arm 3. The upper ends of the first swing arm 2 and the upper ends of the second swing arm 3 are both used to install the peeling roller.

[0033] principle: During installation, the upper ends of both the first swing arm 2 and the second swing arm 3 are used to install peeling rollers. Specifically, for either the first swing arm 2 or the second swing arm 3, if its middle portion is hinged to the peeling roller frame 1, the peeling roller installed at its upper end is the moving peeling roller 10; if its middle portion is fixedly connected to the peeling roller frame 1, the peeling roller installed at its upper end is the fixed peeling roller 11. The moving peeling roller 10 can be installed at the upper end of either the first swing arm 2 or the second swing arm 3, and two additional fixed peeling rollers 11 are added between the two moving peeling rollers 10, mounted on the peeling roller frame 1. Alternatively, one of the upper ends of the first swing arm 2 and the second swing arm 3 can be fitted with a moving peeling roller 10, and the other with a fixed peeling roller 11.

[0034] Preferably, during installation, the two sets of peeling roller constant pressure tensioning mechanisms of this utility model are arranged opposite to each other and can share the same peeling roller frame 1. The two ends of the same peeling roller are respectively installed on the two sets of peeling roller constant pressure tensioning mechanisms of this utility model.

[0035] Note: The telescopic cylinder 4 and the first swing arm 2 can be fixedly connected, and the deflection of the elastic element 5 compensates for the swing components of the first swing arm 2 and the second swing arm 3.

[0036] During operation, pressure is supplied to the telescopic cylinder 4 via a hydraulic or pneumatic system. The telescopic end of the cylinder 4 extends under hydraulic or pneumatic pressure. The telescopic cylinder 4 and the elastic element 5 push the lower ends of the first swing arm 2 and the second swing arm 3 to swing away from each other, while the upper ends of the first swing arm 2 and the second swing arm 3 swing towards each other. This causes the peeling moving roller 10 to approach the peeling fixed roller 11 and generate a certain pressure, achieving tension. Since the tension pressure between the peeling moving roller 10 and the peeling fixed roller 11 corresponds to the pressure of the telescopic cylinder 4, maintaining the pressure of the telescopic cylinder 4 is sufficient to maintain the tension of the peeling moving roller 10 and the peeling fixed roller 11. Even if the elasticity of the elastic element 5 fatigues, it will not cause the peeling roller tension to become unstable. Simultaneously, the pressure system can supply pressure to multiple telescopic cylinders 4, allowing for simultaneous adjustment of the tension of multiple sets of peeling rollers, thus improving work efficiency.

[0037] By employing this invention, the telescopic cylinder 4 applies pressure to the first swing arm 2 and the second swing arm 3, causing them to swing in opposite directions. This achieves tension between the peeling moving roller 10 and the peeling fixed roller 11 at the upper ends of the first swing arm 2 and the second swing arm 3. By controlling the constant pressure of the telescopic cylinder 4, the tension between the peeling moving roller 10 and the peeling fixed roller 11 can be kept constant, avoiding tension fatigue and improving the reliability of the peeling rollers. At the same time, the telescopic cylinders 4 of multiple sets of peeling rollers in the whole machine can be controlled simultaneously through a single pressure system. When adjusting the tension, it is not necessary to adjust each set of peeling rollers separately, which improves convenience and adjustment efficiency, and also improves the consistency of the tension of multiple sets of peeling rollers. In addition, the pressure between the telescopic cylinder 4 and the second swing arm 3 is transmitted through the elastic element 5, which helps to buffer the vibration of the peeling rollers during operation, avoids mechanical damage, and extends the service life of the device.

[0038] Furthermore, the fixed end of the telescopic cylinder 4 is hinged to the first swing arm 2, and the telescopic end of the telescopic cylinder 4 is fixedly connected to the elastic element 5.

[0039] Note: The telescopic end of telescopic cylinder 4 is its piston rod, and the fixed end of telescopic cylinder 4 is its cylinder body.

[0040] By rotating the telescopic cylinder 4 relative to the first swing arm 2, the amplitude of the relative swing between the first swing arm 2 and the second swing arm 3 is compensated, the deflection of the elastic element 5 is reduced, fatigue of the elastic element 5 is avoided, and the service life of the elastic element 5 is extended.

[0041] Furthermore, the telescopic cylinder 4 has a guide rod 6 fixed to its telescopic end, and the end of the guide rod 6 away from the telescopic cylinder 4 moves through the second swing arm 3; the elastic element 5 is a spring, which is sleeved on the guide rod 6, and the end of the elastic element 5 away from the telescopic cylinder 4 abuts against the second swing arm 3.

[0042] Note: The guide rod 6 moves through the second swing arm 3. The guide rod 6 can move axially and radially relative to the second swing arm 3. When the guide rod 6 moves too much radially relative to the second swing arm 3, it is constrained by the second swing arm 3 to prevent the elastic element 5 from deflecting too much.

[0043] The guide rod 6 supports the elastic element 5, while the second swing arm 3 can restrain the excessive movement of the guide rod 6, thus avoiding the deflection instability of the elastic element 5 and improving the stability of the pressure applied by the telescopic cylinder 4 to the second swing arm 3.

[0044] Furthermore, the guide rod 6 is coaxially arranged with the telescopic end of the telescopic cylinder 4, and the telescopic end of the telescopic cylinder 4 is fixedly fitted with a limiting component 7. One end of the elastic element 5 abuts against the limiting component 7, and the other end of the elastic element 5 abuts against the second swing arm 3.

[0045] This improves the stability of elastic element 5.

[0046] Furthermore, the limiting component 7 is a nut, and the limiting component 7 is threadedly connected to the telescopic end of the telescopic cylinder 4.

[0047] The position of the limiting component 7 is easy to adjust, thereby adapting to the length or fatigue level of the elastic element 5, and it has good flexibility.

[0048] Furthermore, the telescopic cylinder 4 has a pressure channel 41 and an internal threaded connector 42 on the side of the cylinder body. The internal threaded connector 42 is connected to the pressure channel 41, and the pressure channel 41 is connected to the cylinder body of the telescopic cylinder 4. The internal threaded connector 42 is fixed on the outer wall of the cylinder body of the telescopic cylinder 4.

[0049] It is easy to connect to external pressure pipelines and is convenient to install.

[0050] Furthermore, the middle parts of the first swing arm 2 and the second swing arm 3 are both hinged to the peeling roller frame 1.

[0051] The upper ends of the first swing arm 2 and the second swing arm 3 are both used to install peeling moving rollers 10. Two peeling fixed rollers 11 are added between the two peeling moving rollers 10. The peeling fixed rollers 11 are installed on the peeling roller frame 1, thus installing two pairs of peeling rollers, which is a compact structure.

[0052] Furthermore, there are multiple and equal numbers of the first swing arms 2 and the second swing arms 3. The first swing arms 2 and the second swing arms 3 are arranged alternately from one end of the peeling roller frame 1 to the other end. A telescopic cylinder 4 and an elastic element 5 are provided between the nth first swing arm 2 and the nth second swing arm 3, where n is a positive integer.

[0053] Note: n represents the position of the first swing arm 2 and the second swing arm 3, indicating that the first first swing arm 2 and the first second swing arm 3 are a group, the second first swing arm 2 and the second second swing arm 3 are a group, and so on.

[0054] It is convenient to install multiple sets of peeling rollers on the same peeling roller frame 1, and the structure is compact.

[0055] Furthermore, it also includes a pressure supply component 8, which is connected to a pressure supply pipeline 9, and the pressure supply pipeline 9 is connected to each telescopic cylinder 4 through branch lines.

[0056] Preferably, the pressure supply component 8 is a hydraulic pump or a hydraulic system on a peeling machine.

[0057] By controlling the output pressure of the pressure supply component 8, the tension of each set of peeling moving rollers 10 and peeling stationary rollers 11 can be controlled simultaneously, resulting in high adjustment efficiency and good tension consistency.

[0058] Furthermore, the telescopic cylinder 4 is a hydraulic telescopic cylinder, and the pressure supply component 8 is a hydraulic pump.

[0059] It is easy to control hydraulically, has good pressure stability, and is highly safe.
