Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and more specifically to an automatic pressing mechanism for idler roller sealing components and a conveyor. Background Technology

[0002] Idler rollers are an indispensable and important component of conveyors. Their function is to bear the weight and provide rolling support for the conveyor belt. The structure of idler rollers is relatively simple, but due to the generally harsh working environment they operate in, such as mining conveyors, after long-term use, external dust, moisture, and other substances can easily enter the idler roller tube, causing severe wear and corrosion of the bearings, and eventually leading to idler roller failure. To solve this technical problem, it is usually necessary to press sealing rings into the outside of the bearings at both ends of the idler roller tube, and press dust covers into the outside of the sealing rings.

[0003] Chinese Patent Application No. CN202310716090.3 discloses a roller tube sealing cover pressing device. This invention utilizes an inner and outer support to achieve the transfer operation of different pressing processes for the roller tube. Furthermore, by setting a feeding conveyor belt on one side of the outer support and a discharging conveyor belt on the other side, the roller tube is automatically loaded and unloaded, avoiding manual handling of the roller and reducing the labor intensity of workers. However, when pressing rollers of different specifications, it can only adjust the axial length of the roller body, not the pressing position of the pressing head. When the roller radius changes, the pressing head and the center of the roller cannot be aligned, affecting the pressing operation of the sealing ring or dust cover. Moreover, during the pressing operation, the top of the roller is not restricted in its positioning, affecting the stability of the roller sealing assembly pressing operation. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art, and to propose an automatic pressing mechanism and conveyor for idler roller sealing components.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An automatic pressing mechanism for idler roller sealing assemblies includes a base and further includes:

[0007] Limiting plates, two of which are slidably disposed on both sides of the base, and each of the two limiting plates is provided with a guide plate, the two sets of guide plates forming a track platform for the movement of the roller body;

[0008] The adjustable distance assembly has two sets symmetrically arranged on both sides of the base, and is used to adjust the position of the same-side limiting plate on the base;

[0009] A pressing mechanism is connected to an adjusting assembly. The pressing mechanism includes a guide seat, a pressing part disposed on the guide seat, and a pressing assembly for adjusting the height of the guide seat.

[0010] Preferably, the guide plate includes a waiting area V-shaped groove and a working area V-shaped groove fixedly connected to the limiting plate, a connecting plate disposed between the waiting area V-shaped groove and the working area V-shaped groove, and transfer plates disposed on the waiting area V-shaped groove and the working area V-shaped groove respectively.

[0011] Preferably, the adjusting assembly includes a mounting plate fixedly connected to the base, a rotating shaft rotatably connected to the mounting plate, a swing rod fixedly connected to the rotating shaft, and a first slider movably disposed at the end of the swing rod. The limiting plate has a first sliding groove for the first slider to slide. The adjusting assembly also includes a first lead screw rotatably connected to the mounting plate, a drive motor fixedly disposed on the mounting plate and used to drive the first lead screw to rotate, a sleeve threadedly connected to the first lead screw, a connecting rod movably connected to the sleeve, and a connecting block movably connected to the connecting rod via a pin. The connecting block is connected to the swing rod.

[0012] Preferably, the top pressing assembly includes a fixed seat fixed on the limiting plate and at the same height as the V-groove of the working area, a movable seat slidably connected to the limiting plate, a pressure seat fixedly connected to the movable seat, and a hinge portion disposed between the fixed seat and the movable seat, wherein the guide seat is connected to the hinge portion.

[0013] Preferably, the top pressing assembly further includes a fixed plate fixed on the swing rod and an elastic element disposed between the fixed plate and the connecting block. The connecting block is slidably connected to the swing rod, and the connecting block is movably connected to a second slider through a pin on its outer support plate. The movable seat is provided with a second slide groove for the second slider to slide.

[0014] Preferably, the hinge part includes two upper hinge rods disposed on the movable seat, two lower hinge rods disposed on the fixed seat, and a movable plate hinged between the upper and lower hinge rods on the same side. An elastic telescopic rod is provided between the two movable plates and the outer wall of the guide seat, and a guide rod is provided at the bottom of the guide seat that is slidably connected to the fixed seat.

[0015] Preferably, the pressing part includes a driving device fixed on both sides of the guide seat, a movable plate connected to the movable end of the driving device, a movable rod fixedly connected to the movable plate, and a pressing head disposed at the end of the movable rod, wherein the pressing head is slidably connected inside the guide seat.

[0016] Preferably, the pressure seat includes a first support plate fixedly connected to the movable seat, a reciprocating screw rotatably connected to the first support plate via a bearing, a nut seat threadedly connected to the reciprocating screw, a lifting plate fixedly connected to the nut seat and slidably connected to the limiting plate, and a V-shaped seat fixedly mounted on the lifting plate. A second support plate is fixedly mounted on the limiting plate, and a one-way gear is provided on the second support plate that is vertically slidably connected to the reciprocating screw. A rack plate that meshes with the one-way gear is fixedly mounted on the movable plate.

[0017] Preferably, the lifting plate is fixedly provided with a lifting rod that is slidably connected to the limiting plate, and the bottom of the lifting rod is fixedly provided with a first lifting seat and a second lifting seat with the same structure. The first lifting seat is slidably connected to the V-shaped groove of the waiting area, and the second lifting seat is slidably connected to the V-shaped groove of the working area.

[0018] The present invention also discloses a conveyor, including a plurality of idler bodies pressed by an automatic pressing mechanism of an idler sealing assembly, and a conveyor frame, wherein the plurality of idler bodies are rotatably connected to the conveyor frame, and a conveyor belt is provided between the plurality of idler bodies.

[0019] As can be seen from the above technical solutions, the present invention has the following beneficial effects:

[0020] 1. In this invention, when the adjusting component is working, it drives the hinge part to move together, so that the upper hinge rod and the lower hinge rod move closer to each other, thereby causing the guide seat connected to the hinge part to shift and adjust the pressing position of the guide seat, so that the pressing position of the guide seat is in the same straight line as the axis of the idler body. While adjusting the position of the limiting plate, the pressing position of the guide seat is adjusted, so that the pressing position of the guide seat is aligned with the axis of the idler. This allows the pressing mechanism to adapt to different idler bodies and make quick adjustments, thereby improving the pressing efficiency of the idler.

[0021] 2. In this invention, when the pitch adjustment component is working, the drive motor drives the first lead screw to rotate, and the sleeve moves axially along the first lead screw. When the sleeve moves, it pushes the swing rod through the connecting rod and the connecting block. The swing rod swings around the pivot, and the first slider at the end of the swing rod slides in the first slide groove. The first slider pushes the limiting plate to move laterally on the base. The two limiting plates on the base move closer to each other until they abut against the two ends of the roller body, limiting the two sides of the roller body to avoid skewing during pressing and to ensure the stability of the roller sealing component during installation.

[0022] 3. In this invention, after the limiting plate abuts against the end of the idler body, the drive motor continues to run, and the sleeve continues to apply a pushing force to the connecting block through the connecting rod. When the limiting plate can no longer move, the connecting block slides on the swing rod and compresses the elastic element. When the connecting block slides down the swing rod, it drives the second slider to slide in the second slide groove. The second slider drives the moving seat to slide on the limiting plate, so that the pressure seat connected to the moving seat moves down until the pressure seat abuts against the top of the idler body. The V-shaped seat of the pressure seat cooperates with the V-shaped groove of the working area to limit the idler body, preventing the idler body from tilting when it is pressed, and ensuring the quality of the idler pressing.

[0023] 4. In this invention, when the drive device is reset, the rack plate drives the one-way gear to rotate, causing the nut seat to move upward along the reciprocating screw. The V-shaped seat rises to release the limit on the idler roller. The lifting rod drives the first lifting seat and the second lifting seat to move upward, completing the automatic unloading of the idler roller. The idler roller in the waiting area automatically enters the working area, and new idler rollers are added to the waiting area, realizing the switching of idler roller station and continuous feeding, ensuring the efficiency of idler roller pressing.

[0040] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions:

[0041] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 11 This embodiment provides an automatic pressing mechanism for a roller sealing assembly, including a base 1, and further including: a limiting plate 2, an adjusting component, and a pressing mechanism. Two limiting plates 2 are provided and slidably disposed on both sides of the base 1. The two limiting plates 2 are disposed on both sides of the base 1 via a sliding device (such as a slide rail or slide groove). Each of the two limiting plates 2 is provided with a guide plate 3, and the two sets of guide plates 3 form a track platform for the movement of the roller body 4, used to support and guide the movement of the roller body 4. An infeed conveyor belt and an outfeed conveyor belt can be respectively provided on both sides of the guide plate 3 for feeding and discharging the roller body 4. Two sets of adjusting components are provided and symmetrically disposed on both sides of the base 1, used to adjust the position of the limiting plates 2 on the same side on the base 1. The pressing mechanism is connected to the adjusting component and includes a guide seat 5 and a pressing mechanism disposed on the guide seat 5. The device includes a pressing assembly for adjusting the height of the guide seat 5. The guide seat 5 has a material guiding channel inside for storing and directional conveying of seals (such as sealing rings and dust covers). The outlet of the material guiding channel is aligned with the bearing seat position at the end of the roller body 4. The pressing part is installed on the guide seat 5. In a common embodiment, the pressing part includes a drive device 13 fixed on both sides of the guide seat 5, a moving plate 131 connected to the movable end of the drive device 13, a moving rod 132 fixedly connected to the moving plate 131, and a pressing head 133 provided at the end of the moving rod 132. The pressing head 133 is slidably connected in the guide seat 5. The drive device 13 includes, but is not limited to, at least one of a hydraulic cylinder, a pneumatic cylinder, and an electric push rod. The pressing head 133 adopts the prior art. The shape of the pressing head 133 matches the seal to be pressed to ensure uniform pressure application.

[0042] Specifically, according to the specifications (length, diameter) of the roller body 4 to be pressed, the spacing between the two limit plates 2 is automatically adjusted by the spacing adjustment component to form a suitable track platform. When the spacing adjustment component is working, it drives the top pressing component to adjust the height of the guide seat 5 and the pressing part so that the center of the pressing head 133 is aligned with the axis of the roller body 4. The sealing parts, such as sealing rings or dust covers, are placed in the material storage or guiding channel of the guide seat 5. The roller body 4 is placed on the track platform formed by the guide plate 3 by an external conveying device or manually.

[0043] It should be noted that the guide plate 3 includes a waiting area V-groove 301 and a working area V-groove 302 fixedly connected to the limiting plate 2, a connecting plate 303 disposed between the waiting area V-groove 301 and the working area V-groove 302, and transfer plates 304 respectively disposed on the waiting area V-groove 301 and the working area V-groove 302. When the sealing ring or dust cover is pressed, the two idler roller bodies 4 are first rolled off the feeding conveyor belt on one side of the base 1 onto the guide plate 3, with one placed in the working area V-groove 302 and the other placed in the waiting area V-groove 301. Then the feeding conveyor belt is stopped, and the idler roller body 4 in the working area V-groove 302 is in the pressing position, with its two end bearing seats facing the pressing parts on both sides. The pressing parts are running. The pressure head 133 presses the seal into the bearing seat at the end of the idler body 4 with constant pressure and speed. Before pressing, the length of the moving rod 132 can be adjusted to ensure that the pressing depth and pressure meet the preset values, preventing over-pressing or incomplete pressing. The pressing mechanisms at both ends of the idler body 4 can usually work simultaneously to complete the pressing of the seals at both ends in one go, greatly improving efficiency. After pressing, the pressing part returns to its original position. The pressed idler body 4 is automatically moved out by the guide plate 3 and conveyed to the next process line by the feeding conveyor belt. Compared with the traditional pressing method, the entire process of idler loading, positioning, seal feeding, pressing, and unloading is fully or semi-automated. It has strong continuous operation capability, greatly reduces manual intervention and process time, and significantly improves production efficiency.

[0044] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As a preferred technical solution in this embodiment, the adjustable distance assembly includes a mounting plate 6 fixedly connected to the base 1, a rotating shaft 601 rotatably connected to the mounting plate 6, a swing rod 602 fixedly connected to the rotating shaft 601, and a first slider 603 movably disposed at the end of the swing rod 602. A first groove 201 for sliding the first slider 603 is provided on the limiting plate 2. The mounting plate 6 serves as the basic support for the entire assembly. The adjustable distance assembly also includes a first lead screw 7 rotatably connected to the mounting plate 6, a drive motor 701 fixedly disposed on the mounting plate 6 and used to drive the first lead screw 7 to rotate, a sleeve 702 threadedly connected to the first lead screw 7, a connecting rod 703 movably connected to the sleeve 702, and a connecting block 704 movably connected to the connecting rod 703 via a pin. The connecting block 704 is connected to the swing rod 602.

[0045] Specifically, when the pitch adjustment assembly is working, the drive motor 701 drives the first lead screw 7 to rotate, and the sleeve 702 moves axially along the first lead screw 7. When the sleeve 702 moves, it pushes the swing rod 602 through the connecting rod 703 and the connecting block 704. The swing rod 602 swings around the rotating shaft 601. The first slider 603 at the end of the swing rod 602 slides in the first slide groove 201, and the first slider 603 pushes the limiting plate 2 to move laterally on the base 1. The two limiting plates 2 on the base 1 approach each other until they abut against the two ends of the roller body 4, limiting the two sides of the roller body 4 to prevent skewing during pressing.

[0046] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As a preferred technical solution in this embodiment, the top pressing assembly includes a fixed seat 8 fixed on the limiting plate 2 and at the same height as the working area V-groove 302, a movable seat 9 slidably connected to the limiting plate 2, a pressing seat 10 fixedly connected to the movable seat 9, and a hinge part disposed between the fixed seat 8 and the movable seat 9. The fixed seat 8 is at the same height as the working area V-groove 302 to ensure accurate positioning of the roller body 4 to be pressed. The guide seat 5 is connected to the hinge part.

[0047] Furthermore, the top pressing assembly also includes a fixed plate 11 fixed on the swing rod 602 and an elastic element 111 disposed between the fixed plate 11 and the connecting block 704. The connecting block 704 is slidably connected to the swing rod 602. The connecting block 704 is movably connected to the second slider 112 through a pin on its outer support plate. The moving seat 9 is provided with a second slide groove 901 for the second slider 112 to slide.

[0048] Furthermore, the hinge part includes two upper hinge rods 12 disposed on the movable seat 9, two lower hinge rods 121 disposed on the fixed seat 8, and a movable plate 122 hinged between the upper hinge rods 12 and the lower hinge rods 121 on the same side. Both movable plates 122 are provided with elastic telescopic rods 501 between themselves and the outer wall of the guide seat 5. The bottom of the guide seat 5 is provided with a guide rod 502 that is slidably connected to the fixed seat 8.

[0049] Specifically, after the limiting plate 2 abuts against the end of the idler roller body 4, the drive motor 701 continues to run, and the sleeve 702 continues to apply a pushing force to the connecting block 704 through the connecting rod 703. When the limiting plate 2 can no longer move, the connecting block 704 slides on the swing rod 602 and compresses the elastic element 111. When the connecting block 704 slides down the swing rod 602, it drives the second slider 112 to slide in the second slide groove 901, and the second slider 112 drives the moving seat 9 to slide on the limiting plate 2, so that the pressure seat 10 connected to the moving seat 9 moves down until the pressure seat 10 and the moving seat 9 move down. The top of the idler body 4 abuts against the V-shaped seat 1005 of the pressure seat 10, which, together with the V-shaped groove 302 of the working area, limits the idler body 4 to prevent it from tilting up when it is pressed. When the movable seat 9 moves down relative to the fixed seat 8, the hinge between the movable seat 9 and the fixed seat 8 automatically rotates and swings, causing the upper hinge rod 12 and the lower hinge rod 121 to move closer to each other, thereby causing the guide seat 5 connected to the hinge to move and adjust the pressing position of the guide seat 5 so that the pressing position of the guide seat 5 is on the same straight line as the axis of the idler body 4. The pressing position of the guide seat 5 is adjusted at the same time as the position of the limiting plate 2.

[0050] Reference Figures 1-11As a preferred technical solution in this embodiment, the pressure seat 10 includes a first support plate 1001 fixedly connected to the movable seat 9, a reciprocating screw 1002 rotatably connected to the first support plate 1001 via a bearing, a nut seat 1003 threadedly connected to the reciprocating screw 1002, a lifting plate 1004 fixedly connected to the nut seat 1003 and slidably connected to the limiting plate 2, and a V-shaped seat 1005 fixedly mounted on the lifting plate 1004. A rubber pad is provided on the V-shaped seat 1005 to prevent damage to the idler roller. The first support plate 1001 serves as the basic support for the entire pressure seat 10. A second support plate 14 is fixedly mounted on the limiting plate 2, and the second support plate 14 is provided with a reciprocating screw... A one-way gear 141 is vertically slidably connected to the lead screw 1002; the reciprocating lead screw 1002 should have a guide groove smaller than the width of its track groove, and the inner wall of the one-way gear 141 is provided with a guide bar that slides in the guide groove. Through the cooperation between the guide bar and the guide groove, when the one-way gear 141 rotates, it drives the reciprocating lead screw 1002 to rotate through the guide bar. A rack plate 142 that meshes with the one-way gear 141 is fixed on the moving plate 131. The one-way gear 141 is the prior art, which ensures that the movement of the rack plate 142 can only drive the gear to rotate in one direction, thereby driving the lead screw, while it idles when moving in the opposite direction, thus realizing the one-way transmission and coupling of the movement direction.

[0051] Furthermore, a lifting rod 15 is fixed on the lifting plate 1004 and slidably connected to the limiting plate 2. The bottom of the lifting rod 15 is fixed with a first lifting seat 151 and a second lifting seat 152 with the same structure. The first lifting seat 151 is slidably connected to the V-shaped groove 301 of the waiting area, and the second lifting seat 152 is slidably connected to the V-shaped groove 302 of the working area.

[0052] Specifically, during the pressing operation, the movable end of the drive device 13 moves the movable rod 132 via the movable plate 131, causing the pressure head 133 at the end of the movable rod 132 to press against the sealing ring or dust cover inside the guide seat 5. The sealing ring or dust cover is pressed into the roller body 4, sealing the roller body 4. Due to the one-way gear 141, during pressing, the movable plate 131 moves, causing the rack plate 142 to shift. The meshing of the rack plate 142 and the one-way gear 141 does not cause the one-way gear 141 to drive the reciprocating screw 1002 to rotate. After the pressing process is completed, the drive device 13 drives the movable plate 131 to reset. At this time, the rack plate 142 is rotated. When the strip 142 moves back, its meshing with the one-way gear 141 causes the one-way gear 141 to drive the reciprocating screw 1002 to rotate. The nut seat 1003 moves upward along the axial direction of the reciprocating screw 1002. The nut seat 1003 drives the V-shaped seat 1005 to move upward through the lifting plate 1004, so that the V-shaped seat 1005 no longer presses down on the top of the idler body 4. At this time, the upper side of the idler body 4 is no longer restricted. As the lifting plate 1004 rises, the lifting plate 1004 drives the first lifting seat 151 and the second lifting seat 152 to move upward through the lifting rod 15. This causes the second lifting seat 152 to lift the idler body 4 in the V-groove 302 of the working area. 4. The roller body 4 is moved out of the V-groove and onto the feeding conveyor belt on the other side of the base 1 via the connected transfer plate 304. The first lifting seat 151 lifts the roller body 4 in the V-groove 301 of the waiting area. The roller body 4 in the V-groove 301 of the waiting area moves out of the V-groove and into the connecting plate 303 until it is abutted by the second lifting seat 152. As the rack plate 142 and the one-way gear 141 continue to mesh, the nut seat 1003 moves back after moving to the end of the track groove of the reciprocating screw 1002. The nut seat 1003 drives the lifting plate 1004 to move down, and when the lifting plate 1004 moves down, it drives the first lifting seat 151 and the second lifting seat 152 through the lifting rod 15. As the second lifting seat 152 moves downward, it no longer limits the idler body 4 at the connecting plate 303. The idler body 4 on the connecting plate 303 moves to the V-shaped groove 302 in the working area. As the lifting plate 1004 continues to move downward, the pressure seat 10 connected to the lifting plate 1004 resets. The pressure seat 10 presses down and positions the idler body 4 on the lower side. Then, the feeding conveyor belt (here referring to the conveyor frame 16 or a similar structure) continues to transport an idler body 4 to the waiting area V-shaped groove 301 for material preparation. The control drive equipment 13 repeats its work to perform pressing operations on the idler body 4 that is currently in the working area V-shaped groove 302, thereby realizing idler station switching and continuous material supply, and ensuring idler pressing efficiency.

[0053] Reference Figure 12This embodiment also provides a conveyor, including a plurality of idler bodies 4 pressed by the aforementioned automatic pressing mechanism for an idler sealing assembly, and a conveyor frame 16, wherein the plurality of idler bodies 4 are rotatably connected to the conveyor frame 16, and a conveyor belt is provided between the plurality of idler bodies 4.
