Description
Technical Field
[0001] The present invention relates to the technical field of belt deviation correction, and in particular to a reset mechanism and an automatic belt deviation correction and guiding device. Background Art
[0002] A conveyor belt, also known as a transport belt, is a rubber, fiber, and metal composite product or a plastic and fabric composite product used to carry and transport materials in a belt conveyor. It is widely used in industries such as cement, coking, metallurgy, chemical engineering, and steel for short-distance and small-capacity transportation. In agriculture, industrial and mining enterprises, and the transportation industry, it is widely used to transport various solid bulk and powdered materials or finished products. The conveyor belt can transport materials continuously, efficiently, and at a large inclination angle, with safe operation, simple use, easy maintenance, low transportation costs, and can shorten the transportation distance, reduce project costs, and save manpower and material resources.
[0003] During actual use, belt deviation is one of the most common faults in the operation of a belt conveyor. When the belt deviates during operation, the belt shifts towards one side of the idler. At this time, as the running length increases, the degree of deviation will gradually increase, and the height difference between the two sides of the belt edge will also gradually increase. Moreover, belt deviation may also cause abnormal friction with the frame, resulting in severe wear of the belt edge and affecting its service life. Summary of the Invention
[0004] Therefore, the technical problem to be solved by the present invention is that belt deviation may also cause abnormal friction with the frame, resulting in severe wear of the belt edge.
[0005] The above technical problem is solved by the following technical solution: The present invention provides a reset mechanism, which includes a conveyor wheel and a belt driven by the conveyor wheel, and includes a detection and power generation assembly, including detection wheels provided on both sides of the conveyor wheel and a power generation unit connected coaxially. The detection wheels are driven to rotate by the frictional force when the belt deviates, thereby driving the power generation unit to generate electric energy; a sliding assembly, including a driving unit electrically connected to the power generation unit and a sliding member that can slide in a straight line direction. The driving unit uses the electric energy of the power generation unit to drive the sliding member to slide in a straight line direction; a deviation correction execution assembly, including a connecting rod, a plurality of deviation correction rods connected to the sliding member, and a fixed seat provided inside the conveyor wheel. The fixed ends of the deviation correction rods are rotatably connected to the fixed seat. When the sliding member slides, the deviation correction rods are driven by the connecting rod to expand around the fixed ends, forming a frustum of a cone structure with a gradually increasing diameter from the inside to the outside. The frustum of the cone structure contacts the belt and applies a thrust.
[0006] In a preferred embodiment of the reset mechanism of the present invention: The driving unit includes an electric push rod electrically connected to the power generation unit. When the power generation unit generates electricity, it supplies power to the electric push rod, and the output end of the electric push rod pushes the sliding member to slide in a straight line direction.
[0007] In a preferred embodiment of the reset mechanism of the present invention: The sliding member slidably penetrates through the middle of the fixed seat in a straight line direction.
[0008] In a preferred embodiment of the reset mechanism of the present invention: The number of deviation correction rods is at least three, the deviation correction rods are evenly distributed along the circumferential direction of the fixed seat, and the axis of symmetry of the frustum cone structure formed when the deviation correction rods are unfolded coincides with the center line of the belt.
[0009] In a preferred embodiment of the reset mechanism of the present invention: A driving block is slidably arranged inside the deviation correction rod, a reciprocating screw is threadedly connected to the middle of the driving block, a rotating cylinder is fixedly arranged at one end of the reciprocating screw, the deviation correction rod is rotatably connected to the rotating cylinder, and the rotating cylinder is rotatably connected to the fixed seat through a rotating shaft.
[0010] In a preferred embodiment of the reset mechanism of the present invention: A plurality of one-way rotating wheels are fixedly arranged on the driving block, a plurality of pushing belts are arranged outside the deviation correction rod, and the one-way rotating wheels are in contact with the inner sides of the pushing belts.
[0011] In a preferred embodiment of the reset mechanism of the present invention: When the driving block slides from the first position to the second position, the one-way rotating wheels drive the pushing belts to rotate, and when the pushing belts rotate, a driving force along the deviation correction direction is applied to the contacted belt.
[0012] In a preferred embodiment of the reset mechanism of the present invention: Protrusions are arranged on the contact surfaces of the one-way rotating wheels and the pushing belts, and the protrusions increase the friction between the one-way rotating wheels and the pushing belts.
[0013] To solve the above technical problems, the present invention also provides the following technical solution: A belt automatic deviation correction and guiding device, including a reset mechanism, and a cylinder body sleeved on the part of the sliding member penetrating through the fixed seat, a piston fixed to the sliding member is slidably arranged inside the cylinder body; a damping block fixed inside the cylinder body, dividing the internal space of the cylinder body into a first cavity and a second cavity, and a plurality of damping holes are opened on the damping block; an elastic member fixed inside the second cavity; a return spring sleeved outside the sliding member, one end of which is fixed to the sliding member and the other end abuts against the fixed seat.
[0014] In a preferred embodiment of the reset mechanism of the present invention: The elastic member is an airbag, the airbag is fixed to the inner wall of the second cavity, the airbag is compressed when the medium flows into the second cavity, and when the airbag restores its deformation, it squeezes the medium to flow back to the first cavity through the damping holes.
[0015] The beneficial effects of the present invention are as follows: The power generation unit is driven by the friction generated when the detection wheel is offset from the belt, converting mechanical energy into electrical energy to provide power for the driving unit and the sliding assembly, without the need for external power input. Compared with traditional deviation correction systems that rely on external power sources, it has significant energy-saving and independence. Its compact power generation unit structure further enhances the applicability and durability of the device in harsh environments.
[0016] By evenly distributing multiple rectifying rods along the circumference of the fixed seat, a truncated conical structure is formed with its axis of symmetry precisely coinciding with the center line of the belt, applying a balanced thrust to the belt. This avoids local stress concentration, thereby significantly improving the rectifying accuracy and stability. Compared with the traditional rectifying mechanisms with single-direction or non-uniform thrust, the truncated conical structure of the present invention exhibits excellent rectifying synchronism and trajectory adjustment ability.
[0017] By setting a friction drive structure of a one-way runner and a pushing belt on the driving block, the function of applying a rectifying thrust only in a specific direction is realized. This avoids reverse movement interference, thereby significantly enhancing the reset effect of belt rectification. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the specific embodiments and the drawings.
[0026] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may change according to the intentions of those of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the overall description of the present invention.
[0027] Refer toFigure 1-3 , this embodiment provides a reset mechanism, including a detection and power generation assembly 2, which includes detection wheels 21 arranged on both sides of a conveying wheel 1 and a coaxially connected power generation unit 22. The detection wheels 21 are driven to rotate by the frictional force when the belt 11 is offset, thereby driving the power generation unit 22 to generate electric energy; a sliding assembly 3, which includes a driving unit 31 electrically connected to the power generation unit 22 and a sliding member 32 that can slide in a straight line direction. The driving unit 31 uses the electric energy of the power generation unit 22 to drive the sliding member 32 to slide in a straight line direction; a deviation correction execution assembly 4, which includes a connecting rod 41, a plurality of deviation correction rods 42 connected to the sliding member 32, and a fixed seat 43 arranged inside the conveying wheel 1. The fixed ends of the deviation correction rods 42 are rotatably connected to the fixed seat 43. When the sliding member 32 slides, the connecting rod 41 drives the deviation correction rods 42 to expand around the fixed ends, forming a frustum of a cone structure with a gradually increasing diameter from the inside to the outside. The frustum of the cone structure contacts the belt 11 and applies a thrust force; the detection and power generation assembly 2 detects the offset of the belt 11 and generates electric energy, drives the sliding assembly 3 to make the sliding member 32 slide, and then forms a frustum of a cone structure through the deviation correction execution assembly 4 to contact the belt 11 and apply a thrust force, realizing automatic belt deviation correction. It is suitable for harsh environments, has a compact structure, a rapid response, and low energy consumption.
[0028] In this embodiment, the detection wheels 21 can be rollers made of rubber or metal; the power generation unit 22 can be a permanent magnet DC generator, with a compact structure.
[0029] When the belt 11 is offset, the frictional force between the belt 11 and the detection wheels 21 increases, driving the detection wheels 21 to rotate. The rotation of the detection wheels 21 is transmitted to the power generation unit 22 through coaxial connection, driving the movement of the internal rotor thereof.
[0030] The detection wheels 21 sense the offset state of the belt 11 and generate mechanical energy through rotation. The power generation unit 22 converts this mechanical energy into electric energy to provide power for subsequent components.
[0031] The detection wheels 21 directly interact with the belt 11 to capture the offset signal; the electric energy generated by the power generation unit 22 provides energy for the sliding assembly 3.
[0032] The driving unit 31 uses the electric energy provided by the power generation unit 22 to drive the sliding member 32 to make a reciprocating sliding movement in a straight line direction. When the power generation unit 22 outputs current, the driving unit 31 converts the electric energy into a thrust force, pushing the sliding member 32 forward or backward, and the stroke can reach several centimeters.
[0033] The sliding movement of the sliding member 32 provides a driving force for the deviation correction execution assembly 4, converting electric energy into mechanical movement.
[0034] The driving unit 31 receives the electric energy of the power generation unit 22, and the movement of the sliding member 32 directly drives the action of the deviation correction execution assembly 4.
[0035] When the slider 32 slides linearly, the deviation correction rod 42 is pulled or pushed through the connecting rod 41, causing the deviation correction rod 42 to rotate around the fixed end and unfold to form a frustum-shaped structure. The diameter of this structure gradually increases from the inside out and contacts the belt 11.
[0036] The frustum-shaped structure contacts the offset belt 11, and a thrust force is applied through the contact surface to push the belt 11 back to the correct position.
[0037] The sliding motion of the slider 32 drives the rotation of the deviation correction rod 42 through the connecting rod 41 to form a deviation correction structure; the fixed seat 43 provides a stable rotation fulcrum for the deviation correction rod 42 to ensure accurate movement.
[0038] This belt deviation correction device realizes its function through the coordinated work of the power generation detection component 2, the sliding component 3, and the deviation correction execution component 4. When the belt 11 deviates, the detection wheel 21 senses the friction force and rotates, driving the power generation unit 22 to generate electric energy. The electric energy is transmitted to the drive unit 31, which pushes the slider 32 to slide linearly. The slider 32 drives the deviation correction rod 42 to rotate through the connecting rod 41 to form a frustum-shaped structure, which contacts the belt 11 and applies a thrust force to push the belt 11 back to the correct track.
[0039] Utilize the friction force generated by the deviation of the belt 11 to generate electricity, without the need for an external power source, energy-saving and efficient. The mechanical structure is simple, with strong durability, suitable for use in harsh environments.
[0040] Reference Figure 1-2 In an embodiment provided by the present application, the drive unit 31 includes an electric push rod, which is electrically connected to the power generation unit 22. When the power generation unit 22 generates electricity, it supplies power to the electric push rod, and the output end of the electric push rod pushes the slider 32 to slide in a linear direction; the slider 32 slidably penetrates through the middle of the fixed seat 43 in a linear direction. The number of deviation correction rods 42 is three or more, and the deviation correction rods 42 are evenly distributed along the circumference of the fixed seat 43. The axis of symmetry of the frustum-shaped structure formed when the deviation correction rods 42 unfold coincides with the center line of the belt 11; through this technical feature, the deviation correction rods 42 evenly apply a thrust force to the belt 11 to ensure that the belt 11 is evenly stressed, further improving the deviation correction accuracy and stability.
[0041] In this embodiment, the number of deviation correction rods 42 is three or more, and they are evenly distributed along the circumference of the fixed seat 43 to form an annular layout. Each deviation correction rod 42 is a slender member, fixed to the fixed seat 43, and capable of unfolding or folding around a fixed point.
[0042] When the deviation correction rods 42 unfold, they form a frustum-shaped structure, and its axis of symmetry precisely coincides with the center line of the belt 11. The unfolding or folding movement of the deviation correction rods 42 is indirectly driven by the linear sliding of the slider 32.
[0043] The deviation rectifying rod 42 applies a balanced thrust to the belt 11 through its evenly distributed layout, adjusting the running trajectory of the belt 11. Its circumferential distribution design with the fixed seat 43 ensures uniform thrust, and its movement cooperation with the sliding member 32 realizes the synchronization of the deviation rectifying action.
[0044] The detection and power generation assembly 2 drives the electric push rod with the electric energy generated by the power generation unit 22. The electric push rod converts the electric energy into a linear thrust, pushing the sliding member 32 to slide linearly along the middle of the fixed seat 43. The movement of the sliding member 32 further drives multiple deviation rectifying rods 42 to expand synchronously, forming a frustum-shaped structure. The deviation rectifying rods 42 are evenly distributed along the circumference of the fixed seat 43, applying a balanced thrust to the belt 11, adjusting the running trajectory of the belt 11, and making its center line coincide with the axis of symmetry of the frustum-shaped structure, thereby achieving precise deviation rectification.
[0045] Reference Figure 2-5 , as an alternative embodiment, a driving block 421 is slidably arranged inside the deviation rectifying rod 42. A reciprocating screw rod 422 is threadedly connected to the middle of the driving block 421. A rotating cylinder 423 is fixedly arranged at one end of the reciprocating screw rod 422. The deviation rectifying rod 42 is rotatably connected to the rotating cylinder 423, and the rotating cylinder 423 is rotatably connected to the fixed seat 43 through a rotating shaft or a bearing; when the deviation rectifying rod 42 rotates with the friction force of the belt 11, it drives the driving block 421 to rotate synchronously. The driving block 421 is driven by the thread of the reciprocating screw rod 422 to slide axially along the deviation rectifying rod 42; through this technical feature, the reciprocating sliding of the driving block 421 provides a driving force for the subsequent generation of the driving force, enhancing the dynamic response ability of the deviation rectifying mechanism and improving the deviation rectifying efficiency.
[0046] In this embodiment, the deviation rectifying rod 42 is provided with a hollow structure inside. The driving block 421 is installed inside the deviation rectifying rod 42 and can slide freely axially therein.
[0047] The driving block 421 is subjected to an external driving force inside the deviation rectifying rod 42 and performs a linear sliding motion along the axis of the deviation rectifying rod 42.
[0048] As the core moving part, the driving block 421 forms a sliding fit with the deviation rectifying rod 42, providing a basis for subsequent power transmission. Its sliding motion directly responds to the motion state of the deviation rectifying rod 42 and cooperates with the downstream reciprocating screw rod 422 to complete the power transmission.
[0049] The threaded connection between the driving block 421 and the reciprocating screw rod 422.
[0050] Among them, the thread groove of the reciprocating screw rod 422 usually adopts a closed-loop groove structure. This groove is not a simple spiral shape, but is composed of a forward thread groove, a reverse thread groove, and a transition groove connecting the two, forming a complete closed path.
[0051] The spiral directions of the forward thread groove and the reverse thread groove are opposite, so that when the slider moves in the forward groove, it moves linearly in one direction, and when it enters the reverse groove, it moves in the opposite direction, thus realizing a reciprocating motion.
[0052] An internal thread hole is provided in the middle of the driving block 421, which is precisely matched with the external thread of the reciprocating screw 422.
[0053] When the driving block 421 rotates with the deviation rectifying rod 42, the thread of the reciprocating screw 422 drives the driving block 421 to slide reciprocally along the axis of the deviation rectifying rod 42.
[0054] The threaded connection converts the rotational motion into the linear reciprocating motion of the driving block 421, realizing precise power transmission. The reciprocating screw 422, as the driving source, closely cooperates with the driving block 421, and the motion of the driving block 421 directly affects the generation of the driving force.
[0055] One end of the reciprocating screw 422 is fixedly connected to the rotating cylinder 423, and the rotating cylinder 423 is of a cylindrical structure.
[0056] The rotational connection of the rotating cylinder 423 with the deviation rectifying rod 42 and the fixed seat 43
[0057] The rotating cylinder 423 is rotationally connected to the fixed seat 43 through a rotating shaft or a bearing. At the same time, relative rotation is also achieved between the rotating cylinder 423 and the deviation rectifying rod 42 through a bearing.
[0058] The rotating cylinder 423 rotates around the rotating shaft on the fixed seat 43. At the same time, the deviation rectifying rod 42 rotates around its own axis due to the friction of the belt 11. The two achieve independent and coordinated rotational motions through bearings.
[0059] The rotational connection of the rotating cylinder 423 ensures that the rotational motion of the deviation rectifying rod 42 does not interfere with the stability of the fixed seat 43, and at the same time provides a stable rotational support for the reciprocating screw 422. The use of bearings reduces the frictional resistance and ensures the smoothness of the motion.
[0060] The deviation rectifying rod 42 is in direct contact with the belt 11 and is driven by the friction of the belt 11.
[0061] When the belt 11 moves, the frictional force drives the deviation rectifying rod 42 to rotate around its own axis, and the rotation of the deviation rectifying rod 42 is further transmitted to the driving block 421.
[0062] The belt 11, as an external power source, drives the rotation of the deviation rectifying rod 42 through the frictional force, and the deviation rectifying rod 42 transmits this rotational motion to the internal driving block 421.
[0063] The deviation correction rod 42 is driven to rotate by the friction force of the belt 11, and the internal drive block 421 is driven to rotate synchronously by the deviation correction rod 42. The drive block 421 converts the rotational motion into an axial reciprocating sliding motion through the threaded connection with the reciprocating screw rod 422. The reciprocating screw rod 422 is fixed by the rotating cylinder 423 and driven by the rotation of the rotating cylinder 423. The rotating cylinder 423 forms a stable rotational connection with the fixed seat 43 and the deviation correction rod 42 through a rotating shaft or a bearing.
[0064] Reference Figure 3-5 , in an embodiment provided by the present application, a plurality of one-way rotating wheels 424 are fixedly arranged on the drive block 421, and a plurality of pushing belts 425 are arranged outside the deviation correction rod 42. The one-way rotating wheels 424 are in contact with the inner side of the pushing belts 425; when the drive block 421 slides from the first position to the second position, the one-way rotating wheels 424 are self-locked and drive the pushing belts 425 to rotate through the friction force. When the pushing belts 425 rotate, a pushing force along the deviation correction direction is applied to the contacted belt 11; when the drive block 421 slides from the second position to the first position, the one-way rotating wheels 424 rotate freely and the pushing belts 425 stop rotating; through this technical feature, the pushing belts 425 apply a continuous pushing force to the belt 11 in a specific direction, further enhancing the deviation correction and reset effect of the belt 11, and at the same time avoiding interference from reverse movement.
[0065] In this embodiment, a plurality of one-way rotating wheels 424 are fixedly installed on the drive block 421. The one-way rotating wheels 424 are mechanical components with a one-way rotation characteristic, and usually adopt a one-way bearing or a ratchet structure inside to ensure that they can only be forced to rotate in a specific direction.
[0066] The drive block 421 can slide linearly between the first position and the second position. The one-way rotating wheels 424 are fixed to the drive block 421 and move synchronously with the sliding of the drive block 421.
[0067] The one-way rotating wheels 424 are in direct contact with the inner side of the pushing belts 425 through their outer peripheral surfaces to form a friction drive.
[0068] A plurality of pushing belts 425 are arranged outside the deviation correction rod 42. The pushing belts 425 are flexible ring-shaped structures, usually made of rubber or composite materials, and have certain elasticity and friction coefficient.
[0069] When the drive block 421 slides from the first position to the second position, the internal structure of the one-way rotating wheels 424 locks them and they cannot rotate freely, showing a self-locking state.
[0070] When the drive block 421 slides from the second position to the first position, the internal structure of the one-way rotating wheels 424 allows them to rotate freely, showing an idling state.
[0071] In the self-locking state, the one-way runner 424 drives the push belt 425 to rotate through friction as the driving block 421 slides; in the idling state, the one-way runner 424 does not transmit torque and the push belt 425 stops moving.
[0072] The self-locking and idling characteristics of the one-way runner 424 ensure that the push belt 425 rotates only when the driving block 421 slides in a specific direction (from the first position to the second position), avoiding interference during reverse sliding.
[0073] The outer side of the push belt 425 is in direct contact with the surface of the belt 11, and the contact area is usually a flat surface or a friction surface with a certain curvature to increase the contact area and friction force.
[0074] When the push belt 425 rotates, its outer side applies a friction force in a specific direction (the deviation correction direction) to the belt 11, pushing the belt 11 to displace; when the push belt 425 stops rotating, the belt 11 is not affected by the driving force.
[0075] The push belt 425 converts the rotational motion of the one-way runner 424 into a linear displacement of the belt 11 through friction, ensuring that the belt 11 moves in a specific direction.
[0076] The self-locking and idling characteristics of the one-way runner 424 ensure that the driving force is applied only in a specific direction, avoiding interference to the position of the belt 11 during reverse movement and improving the stability of the system.
[0077] Reference Figure 5 Referring to
[0078] In this embodiment, bumps are provided on the contact surfaces of the one-way runner 424 and the push belt 425, and the bumps increase the friction force between the one-way runner 424 and the push belt 425; when the one-way runner 424 is self-locked, the rotational force is more effectively transmitted to the push belt 425 through the bumps.
[0079] Referring to Figure 2 and Figure 6, this embodiment provides an automatic belt deviation correction and alignment device, including a cylinder body 5 sleeved on a part of the sliding member 32 penetrating through the fixed seat 43. A piston 51 fixed to the sliding member 32 is slidably arranged inside the cylinder body 5; a damping block 52 is fixed inside the cylinder body 5, dividing the inner space of the cylinder body 5 into a first cavity and a second cavity. A plurality of damping holes are formed in the damping block 52, and a medium is filled inside the cylinder body 5. The first cavity is for the piston 51 to slide, and the damping holes communicate the first cavity and the second cavity; an elastic member 53 is fixed inside the second cavity. When the piston 51 slides, it pushes the medium in the first cavity to flow into the second cavity through the damping holes. The elastic member 53 is deformed by the extrusion of the medium and stores elastic potential energy. When the elastic member 53 resumes deformation, it pushes the medium to flow back to the first cavity through the damping holes; a return spring 54 is sleeved on the outside of the sliding member 32, one end is fixed to the sliding member 32, and the other end abuts against the fixed seat 43. The return spring 54 is compressed when the sliding member 32 slides, and when the return spring 54 resumes deformation, it pushes the sliding member 32 to reset; when the piston 51 slides with the sliding member 32, a damping force is generated through the flow of the damping holes and the medium, smoothly controlling the movement speed of the sliding member 32. The elastic member 53 stores and releases elastic potential energy through the flow of the medium to assist the medium to flow back. The return spring 54 pushes the sliding member 32 to reset after the belt is corrected, driving the deviation correction rod 42 to return to the initial state, thereby realizing the smooth control of the movement of the sliding member 32 and the automatic reset of the deviation correction rod 42, reducing mechanical shock, and improving the durability and deviation correction repeatability of the mechanism.
[0080] In this embodiment, the cylinder body 5 is a hollow container sleeved on a part of the sliding member 32 penetrating through the fixed seat 43. The sliding member 32 is slidably connected to the fixed seat 43, and a piston 51 is slidably arranged inside the cylinder body 5. The piston 51 is fixedly connected to the sliding member 32 and moves synchronously with the sliding member 32.
[0081] When the sliding member 32 slides along the fixed seat 43 under the drive of an external force, the piston 51 slides axially inside the cylinder body 5.
[0082] The cylinder body 5 provides a sliding space for the piston 51 and restricts the movement trajectory of the piston 51. The fixed connection between the piston 51 and the sliding member 32 ensures that the movement of the sliding member 32 is directly transmitted to the piston 51, and the sliding of the piston 51 provides a driving force for the subsequent medium flow and damping force generation.
[0083] The damping block 52 is fixed inside the cylinder body 5, dividing the inner space of the cylinder body 5 into a first cavity and a second cavity. The damping block 52 is provided with a plurality of damping holes, and a medium (such as a viscous solution) is filled inside the cylinder body 5.
[0084] The damping holes communicate the first cavity and the second cavity, and the medium can flow between the two cavities through the damping holes under the push of the piston 51.
[0085] The damping block 52 restricts the flow velocity of the medium and generates a damping force by separating the cavity and setting damping holes. When the piston 51 slides, it pushes the medium in the first cavity to flow into the second cavity through the damping holes. The aperture and quantity of the damping holes directly affect the flow resistance of the medium, thereby regulating the movement speed of the piston 51 and the slider 32 during resetting.
[0086] The elastic member 53 (such as an airbag or an elastic film) is fixed inside the second cavity and connected to the inner wall of the cylinder body 5.
[0087] When the medium flows from the first cavity into the second cavity through the damping holes, the medium squeezes the elastic member 53, and the elastic member 53 is deformed under pressure and stores elastic potential energy; when the external force decreases or disappears, the elastic member 53 restores its deformation and pushes the medium to flow back into the first cavity through the damping holes.
[0088] The elastic member 53 stores and releases energy through deformation, assisting the reciprocating flow of the medium between the two cavities. Cooperating with the damping block 52 and the piston 51, it regulates the movement speed of the piston 51 and the slider 32 during resetting.
[0089] The return spring 54 is sleeved outside the slider 32, with one end fixed to the slider 32 and the other end abutted against the fixed seat 43.
[0090] When the slider 32 slides, the return spring 54 is compressed and stores elastic potential energy; when the external force decreases or disappears, the return spring 54 restores its deformation and pushes the slider 32 to return along the fixed seat 43.
[0091] The return spring 54 drives the slider 32 to reset through the elastic restoring force, and the abutment with the fixed seat 43 ensures the stability of force transmission. The reset movement of the slider 32 drives the piston 51 to return synchronously. Furthermore, through the cooperation of the medium flow and the elastic member 53, the movement speed of the piston 51 and the slider 32 during resetting is regulated. That is to say, when the belt 11 separates from the detection wheel 21 and the electric push rod is powered off and resets, at this time, the piston 51 is affected by the medium flow during resetting, playing a role of delaying the reset and prolonging the belt deviation correction effect of the deviation correction rod 42 on the belt 11.
[0092] Reference Figure 6 As an alternative embodiment, the elastic member 53 is an airbag. The airbag is fixed to the inner wall of the second cavity. When the medium flows into the second cavity, the airbag is compressed, and when the airbag restores its deformation, it squeezes the medium to flow back into the first cavity through the damping holes.
[0093] In this embodiment, the airbag efficiently stores and releases elastic potential energy through compression and restoration of deformation, enhancing the reflux efficiency of the medium and further improving the smoothness of the movement of the slider 32 and the response speed of the deviation correction rod 42 during resetting.
[0094] Finally, it should be noted that the methods and devices described in detail above are only examples, and those skilled in the art can modify these examples in different ways as long as they do not depart from the scope of the present invention.
