Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically a conveyor with a correction function. Background Technology

[0002] In the food industry, conveyor equipment is commonly used for product transportation. During operation, due to uneven stress on the conveyor belt, it is prone to deviation after a period of time, causing it to detach from its normal running track. Currently, conveyor belt deviation is typically corrected automatically by a conveyor belt correction device. The conveyor includes a frame, with a motor-driven drive roller and a driven roller located at opposite ends of the frame. The conveyor belt wraps around the drive roller and the driven roller. A parallel displacement mechanism is installed at the driven roller to drive it to maintain parallel displacement. This mechanism has two cylinders on each side, which drive the driven roller backward, thus tensioning the conveyor belt.

[0003] In the existing parallel displacement mechanism for driven rollers, during adjustment, a cylinder on one side pushes the driven roller bearing seat on that side to move backward. The driven roller bearing seat on that side pushes a connecting rod on that side, which in turn pushes a rocker arm on that side. The rocker arm on that side drives a rotating shaft to rotate. Since the rotating shaft is connected to a rocker arm on the other side, it causes the rocker arm on the other side to swing. The rocker arm on the other side drives a connecting rod on the other side, which in turn drives the driven roller bearing seat on the other side to move backward. This allows the two driven roller bearings on the left and right sides to move synchronously, ensuring that the driven rollers mounted on the two driven roller bearings can move in parallel.

[0004] However, due to errors in the installation of various components, the driven roller cannot be guaranteed to be perpendicular to the frame. If the driven roller is not perpendicular to the frame, the conveyor belt will veer to one side. Furthermore, since the dimensions and positions of the parts are fixed, the angle between the driven roller and the frame cannot be adjusted. Once the tail conveyor belt veers due to the driven roller not being perpendicular to the frame, it cannot be corrected by adjusting the angle between the head drive roller and the frame. The veered conveyor belt will collide with the frame, causing damage. Damage to the conveyor belt necessitates a shutdown of the entire production line, and repairing the conveyor belt is difficult, resulting in significant losses. Utility Model Content

[0005] To address the above problems, this utility model provides a conveyor with a correction function. By incorporating an adjustable adjustment component in the parallel displacement mechanism, when the driven roller is not perpendicular to the frame, the length of the adjustment component moves the corresponding mounting base, thus making the driven roller perpendicular to the frame. This solves the problem in the prior art where the driven roller cannot be corrected when it is not perpendicular to the frame. In a further embodiment, the adjustment component adopts a three-section threaded connection structure, which is simple in structure and convenient in adjustment operation.

[0006] This utility model provides a conveyor with a correction function, comprising:

[0007] The frame has a pair of main mounting seats at one end and a pair of slave mounting seats at the other end. The slave mounting seats can be moved and adjusted along the extension direction of the frame.

[0008] The drive roller is rotatably mounted on a pair of main mounting bases at both ends;

[0009] The driven roller is rotatably mounted on a pair of driven mounting seats at both ends;

[0010] The conveyor belt is wrapped around the drive drum and the driven drum and drives the transmission by friction with the drive drum.

[0011] It also includes: parallel displacement mechanisms, including:

[0012] A pair of drive units are mounted on the frame and connected to a pair of slave mounts respectively, so as to drive the corresponding slave mounts to move and adjust along the extension direction of the frame;

[0013] A pair of adjustment components, each mounted on a pair of mounting bases, are length-adjustable;

[0014] The linkage transmission component has its two ends respectively located at the ends of a pair of adjustment components away from the mounting base.

[0015] According to this technical solution, by adjusting the length of the adjustment component, the corresponding driven roller can be moved to adjust the posture of the driven roller, that is, the angle between the driven roller and the frame, so that the driven roller is perpendicular to the frame. By correcting it in time, the risk of the conveyor belt running off-center and colliding with the frame, thus avoiding damage to the conveyor belt, can be avoided.

[0016] In the optional technical solution of this utility model, the adjustment component includes:

[0017] The first connector is located on the corresponding mounting base;

[0018] The second connecting member is located at the end corresponding to the linkage transmission component;

[0019] The intermediate connector has one end threaded to the first connector and the other end threaded to the second connector. The threads on the two ends of the intermediate connector are set in opposite directions.

[0020] According to the technical solution, by twisting the intermediate connector, the first connector and the second connector can move toward each other or toward each other to adjust the length of the adjustment component.

[0021] In an optional technical solution of this utility model, the intermediate connecting member is a threaded rod, the first connecting member has a first threaded hole, the second connecting member has a second threaded hole, one end of the threaded rod is threaded into the first threaded hole, and the other end is threaded into the second threaded hole; or...

[0022] The intermediate connecting parts are threaded tubes. The first connecting part is threaded into one end of the threaded tube, and the second connecting part is threaded into the other end of the threaded tube.

[0023] According to this technical solution, when the intermediate connecting member is a threaded rod, the length of the threaded rod within the first threaded hole and the length of the threaded rod within the second threaded hole can be adjusted by screwing the threaded rod, thereby adjusting the length of the adjusting assembly. When the intermediate connecting member is a threaded tube, the length of the first connecting member within the threaded tube and the length of the second connecting member within the threaded tube can be adjusted by screwing the threaded tube, thereby adjusting the length of the adjusting assembly.

[0024] In the optional technical solution of this utility model, for the case where the intermediate connecting member is a threaded rod, the adjustment assembly further includes:

[0025] A first limiting nut, fitted and threaded onto a threaded rod, is used to limit the movement of the first connecting member; and / or...

[0026] The second limiting nut is sleeved and threaded onto the threaded rod. The second limiting nut is used to limit the movement of the second connecting piece.

[0027] According to this technical solution, after the first connecting member is moved to the desired position by screwing the threaded rod, the first limiting nut is screwed onto the first connecting member to limit its position. After the second connecting member is moved to the desired position by screwing the threaded rod, the second limiting nut is screwed onto the second connecting member to limit its position.

[0028] In the optional technical solution of this utility model, for the case where the intermediate connecting member is a threaded pipe, the adjustment component further includes:

[0029] For cases where the intermediate connector is a threaded pipe, the adjustment assembly also includes:

[0030] A first positioning element, sleeved and threadedly connected to a first connecting element, is used to position the first connecting element; and / or

[0031] The second positioning element is sleeved and threaded onto the second connecting element, and is used to position the second connecting element.

[0032] According to this technical solution, after the first connector is moved to the desired position by screwing the threaded tube, the first positioning member is screwed onto one end of the threaded tube to position the first connector. After the second connector is moved to the desired position by screwing the threaded tube, the second positioning member is screwed onto the other end of the threaded tube to position the second connector.

[0033] In an optional technical solution of this utility model, a screwing component is provided on the intermediate connector, which is used to screw the intermediate connector.

[0034] According to this technical solution, a screwing component is provided on the intermediate connector to facilitate screwing the intermediate connector.

[0035] In an optional technical solution of this utility model, the screwing component is sleeved and fixed in the middle of the intermediate connecting component.

[0036] According to this technical solution, when the intermediate connector is a threaded rod, setting the screwing part in the middle of the intermediate connector can provide a larger threaded connection range for the intermediate connector.

[0037] In the optional technical solution of this utility model, the linkage transmission component includes:

[0038] A pair of support seats are mounted on the frame and located at both ends of the driven roller;

[0039] The drive shaft is rotatably mounted on a pair of support seats at both ends;

[0040] A pair of rocker arms are respectively set to a pair of adjustment components. One end of the rocker arm is hinged to the corresponding adjustment component away from the end of the mounting base via a shaft. The other ends of the pair of rocker arms are respectively set at both ends of the drive shaft.

[0041] According to this technical solution, when the driving component moves from the mounting base, the adjusting assembly moves accordingly. The movement of the adjusting assembly causes one end of the rocker arm hinged to it to move, which in turn causes the rocker arm to swing, thereby rotating the drive shaft. Since two rocker arms are connected to each end of the drive shaft, the rotation of the drive shaft synchronously causes the rocker arm on the other side to swing. The swinging of the rocker arm on the other side then drives the movement of the driven roller on the other side of the mounting base via the adjusting assembly, thus achieving synchronous displacement adjustment of both ends of the driven roller.

[0042] In an optional technical solution of this utility model, the conveyor further includes a pair of track assemblies mounted on the frame, with each pair of track assemblies corresponding to a pair of slave mounting seats, and the slave mounting seats sliding on the pair of track assemblies.

[0043] According to this technical solution, the mounting base can slide on the corresponding track assembly to move and adjust along the extension direction of the frame. The mounting base is installed on the track assembly, and the track assembly supports and guides the mounting base, improving the smoothness of sliding.

[0044] In an optional technical solution of this utility model, the track assembly includes a pair of guide rails spaced apart on the frame. The distribution direction of the pair of guide rails is perpendicular to the extension direction of the frame, and they are slidably mounted on the corresponding pair of guide rails from both sides of the mounting base.

[0045] According to this technical solution, by setting a pair of guide rails for each mounting base, the swaying or tilting of the mounting base during movement is prevented, ensuring the smooth movement of the mounting base. Attached Figure Description

Detailed Implementation

[0057] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0058] Please see Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a conveyor with a correction function, including: a frame 10, a drive roller 20, a driven roller 30, a conveyor belt 40, and a parallel displacement mechanism 50. One end of the frame 10 is provided with a pair of main mounting seats, and the other end is provided with a pair of driven mounting seats 11. The driven mounting seats 11 are movable and adjustable along the extension direction of the frame 10. The two ends of the drive roller 20 are rotatably mounted on the pair of main mounting seats. The two ends of the driven roller 30 are rotatably mounted on the pair of driven mounting seats 11. The conveyor belt 40 is wound around the drive roller 20 and the driven roller 30 and is driven by friction with the drive roller 20.

[0059] The parallel displacement mechanism 50 includes a pair of driving members 51, a pair of adjusting components 52, and a linkage transmission component 53. The pair of driving members 51 are mounted on the frame 10 and connected to a pair of slave mounting seats 11 respectively, so as to drive the corresponding slave mounting seats 11 to move and adjust along the extension direction of the frame 10. The pair of adjusting components 52 are respectively mounted on the pair of slave mounting seats 11 and are adjustable in length. The two ends of the linkage transmission component 53 are respectively located at the ends of the pair of adjusting components 52 away from the slave mounting seats 11.

[0060] In traditional conveyors, belt misalignment is a common problem. One major reason is that the driven roller 30 is not perpendicular to the frame 10. When the axis of the driven roller 30 is not perfectly perpendicular to the extension direction of the frame 10, the conveyor belt 40 is subjected to lateral forces during operation, causing it to gradually deviate from its normal operating trajectory and eventually resulting in misalignment. This misalignment not only affects conveying efficiency but may also lead to accelerated wear on the conveyor belt 40, and even damage to both the conveyor belt 40 and the frame 10.

[0061] In this embodiment, an adjustment component 52 is provided in the parallel displacement mechanism 50. The length adjustment function of the adjustment component 52 can precisely adjust the position of the driven roller 30 from the mounting base 11, thereby precisely adjusting the position of the driven roller 30 end, ensuring that the driven roller 30 is perpendicular to the frame 10. This effectively solves the problem of conveyor belt 40 deviation caused by the driven roller 30 not being perpendicular to the frame 10. Since the adjustment component 52 can be dynamically adjusted during conveyor operation, the correction operation can be completed without stopping the machine, greatly reducing downtime caused by deviation and improving production efficiency. Improved operational stability of the conveyor belt 40 not only reduces equipment maintenance costs and downtime but also extends the service life of the conveyor belt 40. This design not only improves equipment operating efficiency but also reduces enterprise operating costs, resulting in significant economic benefits.

[0062] It should be noted that the specific structure of the drive component 51 is not limited here. The drive component 51 can be a cylinder, hydraulic cylinder, electric cylinder or electric telescopic rod or other device that can be telescopically adjusted. The main mounting base and the slave mounting base 11 are bearing seats, and the conveyor belt 40 is a steel belt.

[0063] In one embodiment, such as Figure 4 , Figure 5 As shown, the adjustment component 52 includes: a first connector 521, a second connector 522, and an intermediate connector. The first connector 521 is disposed on the corresponding mounting base 11, the second connector 522 is disposed on the corresponding end of the linkage transmission component 53, one end of the intermediate connector is threadedly connected to the first connector 521, and the other end is threadedly connected to the second connector 522. The threads on both ends of the intermediate connector are arranged in opposite directions.

[0064] Because the threads at both ends of the intermediate connector are in opposite directions, when the intermediate connector is screwed on, the first connector 521 and the second connector 522 will move synchronously but in opposite directions. That is, the first connector 521 and the second connector 522 will move closer to each other, or the first connector 521 and the second connector 522 will move further away from each other, so as to adjust the distance between the first connector 521 and the second connector 522, thereby precisely adjusting the overall length of the adjusting assembly 52. ​​The adjusting assembly 52 has a simple structure and does not require additional transmission mechanisms or complicated operating steps. The operator only needs to simply screw on the intermediate connector to quickly adjust the position of the driven roller 30, so that the driven roller 30 is perpendicular to the frame 10, thereby effectively correcting the deviation of the conveyor belt 40, greatly simplifying the correction process and improving operating efficiency.

[0065] In one specific embodiment, such as Figure 4 As shown, the intermediate connecting member is a threaded rod 523. The first connecting member 521 has a first threaded hole 5211, and the second connecting member 522 has a second threaded hole 5221. One end of the threaded rod 523 is threaded into the first threaded hole 5211, and the other end is threaded into the second threaded hole 5221. By turning the threaded rod 523, the first connecting member 521 and the second connecting member 522 are moved closer to or further away from each other to adjust the length of the threaded rod 523 within the first threaded hole 5211 and the length of the threaded rod 523 within the second threaded hole 5221, thereby adjusting the length of the adjusting assembly 52.

[0066] In another specific embodiment, such as Figure 5 As shown, the intermediate connecting member is a threaded tube 524. The first connecting member 521 is threaded into one end of the threaded tube 524, and the second connecting member 522 is threaded into the other end of the threaded tube 524. By screwing the threaded tube 524, the first connecting member 521 and the second connecting member 522 are moved closer to or further away from each other to adjust the length of the first connecting member 521 and the second connecting member 522 within the threaded tube 524, thereby adjusting the length of the adjusting assembly 52.

[0067] In actual operation, vibration, impact, or long-term operation of the conveyor may cause the threaded connection to loosen, thereby affecting the stability of the adjusting component 52. To solve this problem, this utility model further improves the structure of the adjusting component 52 to prevent changes in the length of the adjusting component 52 due to external forces or other factors, thereby affecting the adjustment effect of the driven roller 30.

[0068] In the preferred embodiment of this utility model, such as Figure 3 , Figure 4As shown, for the case where the intermediate connecting member is a threaded rod 523, the adjusting assembly 52 further includes: a first limiting nut 525, which is sleeved and threadedly connected to the threaded rod 523, and is used to limit the first connecting member 521. After the threaded rod 523 is turned to move the first connecting member 521 to the desired position, the first limiting nut 525 is turned to make it tightly abut against the first connecting member 521, thereby limiting the first connecting member 521.

[0069] In the preferred embodiment of this utility model, such as Figure 3 , Figure 4 As shown, for the case where the intermediate connecting member is a threaded rod 523, the adjusting assembly 52 further includes a second limiting nut 526. The second limiting nut 526 is sleeved on and threadedly connected to the threaded rod 523, and is used to limit the second connecting member 522. After the threaded rod 523 is turned to move the second connecting member 522 to the desired position, the second limiting nut 526 is turned to make it tightly abut against the second connecting member 522, thereby limiting the second connecting member 522.

[0070] When the first limiting nut 525 and the second limiting nut 526 are tightly abutted against the connector, a double locking mechanism is formed. On the one hand, the threaded connection between the threaded rod 523 and the first connector 521, and between the threaded rod 523 and the second connector 522, provides locking and fixation. On the other hand, the mechanical abutment of the first limiting nut 525 and the second limiting nut 526 further limits and locks the connection, thereby effectively preventing the first connector 521 from moving due to slippage or loosening, and avoiding changes in the length of the adjustment assembly 52.

[0071] In the preferred embodiment of this utility model, such as Figure 5 As shown, in the case where the intermediate connecting member is a threaded tube 524, the adjusting assembly 52 further includes a first positioning member 527. The first positioning member 527 is sleeved on and threadedly connected to the first connecting member 521, and is used to position the first connecting member 521. After the threaded tube 524 is screwed to move the first connecting member 521 to the desired position, the first positioning member 527 is screwed to make it tightly abut against one end of the threaded tube 524, thereby positioning the first connecting member 521.

[0072] In the preferred embodiment of this utility model, such as Figure 5As shown, for the case where the intermediate connecting member is a threaded tube 524, the adjusting assembly 52 further includes a second positioning member 528. The second positioning member 528 is sleeved on and threadedly connected to the second connecting member 522, and is used to position the second connecting member 522. After the threaded tube 524 is screwed to move the second connecting member 522 to the desired position, the second positioning member 528 is screwed to make it tightly abut against the other end of the threaded tube 524, thereby positioning the second connecting member 522.

[0073] When the first positioning element 527 is tightly abutted against one end of the threaded tube 524 and the second positioning element 528 is tightly abutted against the other end of the threaded tube 524, a double locking mechanism is formed. On the one hand, the threaded connection between the threaded tube 524 and the first connecting element 521, and between the threaded tube 524 and the second connecting element 522, provides locking and fixation. On the other hand, the mechanical abutment of the first positioning element 527 and the second positioning element 528 further positions and locks the tube, thereby effectively preventing the first positioning element 527 and the second positioning element 528 from moving due to slippage or loosening, and avoiding changes in the length of the adjustment assembly 52.

[0074] In the embodiments of this utility model, such as Figure 4 , Figure 5 As shown, the intermediate connector is equipped with a screwing component 529, which is used to screw the intermediate connector. Operators can easily screw the intermediate connector using the screwing component 529 without directly contacting the intermediate connector, thus avoiding operational difficulties caused by size or position limitations.

[0075] In the preferred embodiment of this utility model, such as Figure 4 , Figure 5 As shown, the screwing component 529 is fitted and fixed in the middle of the intermediate connector. When the intermediate connector is a threaded rod 523, placing the screwing component 529 in the middle of the intermediate connector can make full use of the entire length of the threaded rod 523, thereby providing a larger threaded connection range.

[0076] In the embodiments of this utility model, such as Figure 3 , Figure 6 As shown, the linkage transmission assembly 53 includes: a pair of support seats 531, a transmission shaft 532, and a pair of rocker arms 533. The pair of support seats 531 are mounted on the frame 10 and located at both ends of the driven roller 30. Both ends of the transmission shaft 532 are rotatably mounted on the pair of support seats 531. The pair of rocker arms 533 are respectively provided for a pair of adjustment components 52. One end of the rocker arm 533 is hinged to the end of the corresponding adjustment component 52 away from the driven mounting base 11 via a shaft 534, and the other ends of the pair of rocker arms 533 are respectively located at both ends of the transmission shaft 532. The support seats 531 are bearing seats, and the shafts 534 can be pins or other shaft components.

[0077] Driven by the drive component 51, the driven mounting base 11 on one side connected to it moves, which in turn moves the adjustment component 52 on that side. The adjustment component 52 on that side moves one end of the rocker arm 533 on that side, causing the rocker arm 533 to swing. This causes the transmission shaft 532 connected to the rocker arm 533 to rotate. The transmission shaft 532 causes the rocker arm 533 on the other side to swing. The rocker arm 533 on the other side moves the adjustment component 52 on the other side, which in turn moves the driven mounting base 11 on the other side. This allows for synchronous displacement adjustment of the pair of driven mounting bases 11, thus achieving synchronous displacement adjustment of both ends of the driven roller 30.

[0078] Furthermore, such as Figure 3 , Figure 4 and Figure 8 As shown, one end of the rocker arm 533 is hinged to the end of the corresponding second connecting member 522 away from the intermediate connecting member via a shaft 534. The end of the second connecting member 522 away from the intermediate connecting member has a shaft hole 5222, and one end of the rocker arm 533 has a through hole 5334. The shaft 534 passes through the shaft hole 5222 and the through hole 5334, thus hingedly connecting one end of the rocker arm 533 to the end of the corresponding second connecting member 522 away from the intermediate connecting member. Figure 7 , Figure 8 As shown, the other end of the rocker arm 533 is provided with a through hole 5335, and the other end of the rocker arm 533 is sleeved and fixed to the end of the corresponding drive shaft 532 through the through hole 5335.

[0079] Furthermore, such as Figure 3 , Figure 7 and Figure 8 As shown, the rocker arm 533 includes a vertically arranged main body 5331, an end plate 5332 horizontally disposed at one end of the main body 5331, and a pair of assembly parts 5333 parallelly disposed on the end plate 5332. A through hole 5334 is provided on the assembly part 5333, and a gap 5336 is formed between the pair of assembly parts 5333. The end of the second connecting member 522 away from the intermediate connecting member is located in the corresponding gap 5336. The shaft member 534 passes through the shaft hole 5222 and the through hole 5334 of the pair of assembly parts 5333, so that the pair of assembly parts 5333 are hingedly connected to the end of the corresponding second connecting member 522 away from the intermediate connecting member.

[0080] In the embodiments of this utility model, such as Figure 3As shown, the conveyor also includes a pair of track assemblies 60 mounted on the frame 10. The pair of track assemblies 60 are respectively disposed corresponding to a pair of mounting seats 11, and the pair of mounting seats 11 are respectively slidably mounted on the pair of track assemblies 60. The track assemblies 60 provide stable support for the mounting seats 11 and provide precise directional guidance for the movement of the mounting seats 11, ensuring that the mounting seats 11 move smoothly along the extension direction of the frame 10.

[0081] In one specific embodiment, such as Figure 3 As shown, the track assembly 60 includes a pair of guide rails 61 spaced apart on the frame 10. The distribution direction of the pair of guide rails 61 is perpendicular to the extension direction of the frame 10. The two sides of the mounting base 11 are respectively slidably mounted on the corresponding pair of guide rails 61. The pair of guide rails 61 respectively guide and limit the two sides of the mounting base 11 to prevent the mounting base 11 from shaking or tilting during the movement, and ensure that the mounting base 11 always moves smoothly along the extension direction of the frame 10.

[0082] In one embodiment, see Figure 1 , Figure 2 as well as Figure 9 Of the pair of main mounting seats, one is a fixed bearing seat 12, and the other is an adjusting bearing seat 13. The adjusting bearing seat 13 is connected to an adjusting motor 70 mounted on the frame 10. The frame 10 is equipped with a first detection switch 81 and a second detection switch 82 located on both sides of the conveyor belt 40. The positions of the first detection switch 81 and the second detection switch 82 correspond to the allowable deviation range of the conveyor belt 40 to limit the deviation distance. Both the first detection switch 81 and the second detection switch 82 are connected to the adjusting motor 70. When the conveyor belt 40 deviates and triggers either the first detection switch 81 or the second detection switch 82, the adjusting motor 70 drives the adjusting bearing seat 13 to move in the corresponding direction to correct the conveyor belt 40. When the conveyor belt 40 deviates to the right, it triggers the first detection switch 81 located on the right side. The adjusting motor 70 then drives the adjusting bearing seat 13 to move a set distance to the right, causing the conveyor belt 40 to move to the left, thus achieving the purpose of correcting the conveyor belt 40's deviation. When the conveyor belt 40 deviates to the left, the second detection switch 82 located on the left is activated. The adjusting motor 70 moves the adjusting bearing seat 13 to the left a set distance, causing the conveyor belt 40 to run to the right, thus achieving the purpose of correcting the belt deviation. Figure 9 As shown.

[0083] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
