Description

Technical Field

[0001] This invention is a belt conveyor deviation correction mechanism, belonging to the field of conveyor technology. Background Technology

[0002] Belt conveyors are commonly used equipment for transporting products. To prevent products from deviating during transportation, two rows of straightening rods are usually installed on the frame of the belt conveyor. Under the limiting effect of the two rows of straightening rods, the movement trajectory of the products on the conveyor belt is restricted. Currently, the size of the straightening rods is fixed, and the length of the straightening rods is the same as that of the belt conveyor. For belt conveyors of different lengths, straightening rods of different lengths need to be manufactured, which makes it impossible to make the straightening rods universal. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a belt conveyor deviation correction mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a belt conveyor deviation correction mechanism, comprising a chassis, a metal conveyor belt on the upper side of the chassis, side plates on both sides of the metal conveyor belt, the side plates being connected to the chassis via connectors, a reduction gearbox mounted at one end of one side plate, a motor mounted on the outer surface of the reduction gearbox, the output shaft of the motor being connected to the input shaft of the reduction gearbox, a sprocket rotatably mounted between the two side plates and meshing with the metal conveyor belt, one end of the sprocket being connected to the output shaft of the reduction gearbox, a reversing wheel inside the metal conveyor belt cooperating with the sprocket for supporting the metal conveyor belt, the reversing wheel being rotatably mounted between the two side plates, and two adjustable-length correction rods on the upper side of each of the two side plates, the correction rods being connected to the side plates via multiple sets of adjusting components.

[0005] Specifically, the corrective rod includes multiple short posts. One end of each short post has a threaded hole. A storage hole is formed on the side of each short post away from the threaded hole. A rectangular hole is formed inside each short post, arranged along the length of the short post. The rectangular hole communicates with the storage hole and the threaded hole. A rectangular rod is inserted into the rectangular hole. A first threaded head is connected and fixed to the end of the rectangular rod near the storage hole. A second threaded head is threaded into the threaded hole of one of the short posts near the reversing wheel. A cylindrical head is connected and fixed to the end of the second threaded head outside the threaded hole. The outer diameter of the cylindrical head is the same as the outer diameter of the short column. A plug is fixedly connected to the end of the rectangular rod away from the first threaded head. The plug is slidably installed in the threaded hole. In the initial state, the plug is flush with the opening end of the threaded hole. A spring is sleeved on the end of the rectangular rod near the plug. The spring is installed between the plug and the rectangular hole. The first threaded head in one of the short columns is threadedly connected to the threaded hole on another short column. An internal threaded cap is threadedly connected to the first threaded head in the short column away from the cylindrical head. The outer diameter of the internal threaded cap is the same as the outer diameter of the short column.

[0006] Specifically, the end of the spring away from the plug is connected and fixed with a connecting ring, which is glued to the innermost side of the threaded hole. The connecting ring is sleeved on the rectangular rod, and the end of the spring away from the connecting ring is connected and fixed to the plug.

[0007] Specifically, the connector includes an L-shaped plate. Multiple L-shaped plates are evenly installed on the lower surface of the chassis. A support plate is installed on the vertical part of the L-shaped plate. Both ends of the support plate are threaded with a support column. A connecting plate is provided on the side of the chassis away from the support plate, which is arranged parallel to the support plate. The end of the support column away from the support plate is connected and fixed to the connecting plate. The connecting plate is connected to two side plates. A positioning sleeve for connecting the outrigger is installed in the middle of the side of the support plate away from the chassis.

[0008] Specifically, the adjusting component includes a support. Multiple evenly arranged supports are installed on the opposite sides of the two side plates. A guide hole is opened at the upper part of the side plate facing the side plate. An adjusting rod is inserted into the guide hole. A vertical screw hole is opened on the upper surface of the support. A positioning screw for limiting the relative position between the adjusting rod and the support is threaded into the vertical screw hole. A pressure plate is threaded to the end of the adjusting rod near the straightening rod. A retainer is provided on the side of the pressure plate facing the support. The retainer is sleeved on the adjusting rod and rotatably connected to the adjusting rod. Two straightening rods on the upper part of one side plate are engaged between the pressure plate and the retainer.

[0009] Specifically, a protrusion is fixedly connected to the center of the side of the pressure plate facing the card seat. The protrusion and the pressure plate are integrally formed. The protrusion is located between the two straightening rods. The center of the side of the card seat facing the pressure plate is recessed to form a recess. The protrusion is inserted into the recess.

[0010] Specifically, a through hole is provided in the middle of the side of the card holder facing the support, the adjusting rod passes through the through hole, a limiting ring is provided on the side of the through hole facing the support, the limiting ring is sleeved on the adjusting rod and connected and fixed to the adjusting rod, a third threaded head is connected and fixed to the end of the adjusting rod near the pressure plate, a transverse threaded hole is provided in the middle of one side of the pressure plate to cooperate with the third threaded hole, and the third threaded head is threadedly connected in the transverse threaded hole.

[0011] Specifically, a plurality of crossbars are evenly provided at the lower position between the two side plates, and the two ends of the crossbars are connected to the two side plates respectively by screws.

[0012] Specifically, a plurality of plug-in posts are evenly provided between the two side plates, and plug-in sleeves are fitted at both ends of each plug-in post. The two plug-in sleeves on one plug-in post are connected to the two side plates respectively by screws. The plug-in posts are arranged parallel to the crossbar and perpendicular to each other with the side plates.

[0013] The beneficial effects of this invention are:

[0014] 1. Install the straightening rod between the pressure plate and the bracket, and then adjust the position of the adjusting rod along the guide hole. At this time, the position of the straightening rod changes. When the relative position of the straightening rod and the metal conveyor belt meets the product size requirements, use the positioning screw to limit the relative position of the adjusting rod and the support to adjust the position of the straightening rod, meet the needs of conveying products of different sizes, and expand the scope of application.

[0015] 2. Screw the second threaded end on the cylindrical head into the threaded hole on a short column. At this time, the second threaded end squeezes the plug, and the plug squeezes the spring, causing the spring to deform elastically. At the same time, the plug drives the rectangular rod to move along the rectangular hole. The rectangular hole and the rectangular rod cooperate to restrict the position of the plug and the first threaded end, preventing the plug and the first threaded end from rotating. This allows the first threaded end to move out of the storage hole, and the exposed first threaded end is screwed into another short column, exposing the first threaded end on the other short column to the outside of the storage hole. This process is repeated to complete the assembly of multiple short columns. This allows for the selection of an appropriate number of short columns according to the length of the belt conveyor, eliminating the need to produce straightening rods of different lengths and achieving universality.

[0016] 3. With the support of the spring, the plug is aligned with the open end of the threaded hole. At this time, the plug seals the threaded hole, preventing small debris from entering the threaded hole. At the same time, with the support of the spring, the first threaded head is placed in the storage hole, which hides and protects the first threaded head, preventing the threads on the first threaded head from being damaged due to bumps or other reasons during storage or transportation.

[0017] 4. After the multiple short posts are connected, screw an internal thread cap onto the first threaded head exposed in the short post furthest from the cylindrical head. At this time, the internal thread cap provides protection to the first threaded head.

[0018] 5. Connect the two side plates using a connecting plate, and then connect the connecting plate and the support plate using two pillars to restrict the relative position of the chassis and the two side plates. Install outriggers in the positioning sleeves to facilitate the support of the structure formed by the chassis, side plates and other components. Install multiple crossbars between the two side plates to improve the stability of the installation of the two side plates. Insert plug-in columns into the two opposite plug-in sleeves to further improve the stability of the structure. Attached Figure Description

Detailed Implementation

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Please see Figure 1 , Figure 3 and Figure 4This invention provides a technical solution: a belt conveyor deviation correction mechanism, comprising a chassis 1, a metal conveyor belt 5 on the upper side of the chassis 1, side plates 2 on both sides of the metal conveyor belt 5, a plurality of L-shaped plates 15 evenly installed on the lower surface of the chassis 1, a support plate 14 installed on the vertical part of the L-shaped plate 15, and a support column 16 threadedly connected to both ends of the support plate 14, a connecting plate 17 arranged parallel to the support plate 14 on the side of the chassis 1 away from the support plate 14, the end of the support column 16 away from the support plate 14 being connected and fixed to the connecting plate 17, the connecting plate 17 being connected to the two side plates 2, a positioning sleeve 13 for connecting support legs being installed in the middle of the side of the support plate 14 away from the chassis 1, and a plurality of crossbars 19 evenly arranged at the lower part between the two side plates 2, the two ends of the crossbars 19 being connected to the two side plates 2 respectively by screws. Multiple insertion posts 20 are evenly arranged between the two side plates 2. Each end of the insertion post 20 is fitted with an insertion sleeve 21. The two insertion sleeves 21 on one insertion post 20 are connected to the two side plates 2 respectively by screws. The insertion posts 20 are arranged parallel to the crossbars 19 and perpendicular to the side plates 2. The two side plates 2 are connected by a connecting plate 17. Then, the connecting plate 17 and the support plate 14 are connected by two pillars 16 to complete the restriction of the relative position between the chassis 1 and the two side plates 2. The support legs are installed in the positioning sleeves 13 to facilitate the support of the structure formed by the chassis 1, side plates 2 and other components. Multiple crossbars 19 are installed between the two side plates 2 to improve the stability of the installation of the two side plates 2. Insertion posts 20 are inserted into the two opposite insertion sleeves 21 to further improve the stability of the structure.

[0035] See Figure 1 and Figure 4 A reduction gearbox 4 is installed at one end of one side plate 2. A motor 3 is installed on the outer surface of the reduction gearbox 4. The output shaft of the motor 3 is connected to the input shaft of the reduction gearbox 4. A sprocket 22 that meshes with the metal conveyor belt 5 is rotatably installed between the two side plates 2. One end of the sprocket 22 is connected to the output shaft of the reduction gearbox 4. A reversing wheel 18 that cooperates with the sprocket 22 to support the metal conveyor belt 5 is provided inside the metal conveyor belt 5. The reversing wheel 18 is rotatably installed between the two side plates 2. When the motor 3 is working, it causes the sprocket 22 to rotate after being driven by the reduction gearbox 4. The sprocket 22 and the reversing wheel 18 cooperate with each other to make the metal conveyor belt 5 rotate, thereby facilitating the transportation of products using the rotating metal conveyor belt 5.

[0036] See Figures 1-7Each of the two side plates 2 has two adjustable-length straightening rods 6 on its upper side. Multiple evenly distributed supports 8 are installed on the opposite sides of each side plate 2. A guide hole 23 is provided on the upper part of the side plate 8 facing the side plate 2, and an adjusting rod 7 is inserted into the guide hole 23. A vertical screw hole is provided on the upper surface of the support 8, and a positioning screw 12 for limiting the relative position of the adjusting rod 7 and the support 8 is threaded into the vertical screw hole. A pressure plate 10 is threaded to the end of the adjusting rod 7 near the straightening rod 6. A retainer 9 is provided on the side of the pressure plate 10 facing the support 8, and the retainer 9 is fitted onto the adjusting rod 7. The rod 7 is rotatably connected to the adjusting rod 7. Two straightening rods 6 on the upper side of one side plate 2 are snapped between the pressure plate 10 and the bracket 9. The straightening rods 6 are installed between the pressure plate 10 and the bracket 9. Then, the position of the adjusting rod 7 is adjusted along the guide hole 23. At this time, the position of the straightening rod 6 changes. When the relative position of the straightening rod 6 and the metal conveyor belt 5 meets the needs of the product size, the positioning screw 12 is used to limit the relative position of the adjusting rod 7 and the support 8, so as to realize the adjustment of the position of the straightening rod 6, meet the needs of conveying products of different sizes, and expand the scope of application.

[0037] See Figures 1-7 A protrusion 11 is fixedly connected to the center of the side of the pressure plate 10 facing the card holder 9. The protrusion 11 and the pressure plate 10 are integrally formed. The protrusion 11 is located between the two straightening rods 6. The center of the side of the card holder 9 facing the pressure plate 10 is recessed to form a recess 25, so that the protrusion 11 is inserted into the recess 25, thus limiting the relative position of the card holder 9 and the pressure plate 10. A through hole 24 is opened in the center of the side of the card holder 9 facing the support 8. The adjusting rod 7 passes through the through hole 24. A limiting ring 26 is provided on the side of the through hole 24 facing the support 8. The limiting ring 26 is sleeved on the adjusting rod 7 and connected and fixed to the adjusting rod 7. A third threaded head is fixedly connected to the end of the adjusting rod 7 near the pressure plate 10. A transverse threaded hole that matches the third threaded hole 611 is opened in the center of one side of the pressure plate 10, so that the third threaded head is threadedly connected in the transverse threaded hole, thus completing the assembly of the adjusting rod 7 and the pressure plate 10.

[0038] See Figures 8-12The corrective rod 6 includes multiple short posts 601. One end of each short post 601 has a threaded hole 611. A storage hole 609 is formed on the side of the short post 601 away from the threaded hole 611. A rectangular hole 610 is formed inside each short post 601, arranged along the length of the short post 601. The rectangular hole 610 communicates with the storage hole 609 and the threaded hole 611. A rectangular rod 604 is inserted into the rectangular hole 610. A first threaded head 608 is connected and fixed to the end of the rectangular rod 604 near the storage hole 609. A short post 601 near the reversing wheel 18... A second threaded head 612 is internally threaded into the threaded hole 611. A cylindrical head 602 is fixedly connected to one end of the second threaded head 612 outside the threaded hole 611. The outer diameter of the cylindrical head 602 is the same as the outer diameter of the short column 601. A plug 607 is fixedly connected to one end of the rectangular rod 604 away from the first threaded head 608. The plug 607 is slidably installed inside the threaded hole 611. In its initial state, the plug 607 is flush with the opening end of the threaded hole 611. A spring 606 is sleeved on one end of the rectangular rod 604 near the plug 607. The spring 606 is mounted on the plug 607. Between 07 and the rectangular hole 610, a first threaded head 608 inside a short post 601 is threaded into a threaded hole 611 on another short post 601, causing a second threaded head 612 on a cylindrical head 602 to screw into a threaded hole 611 on a short post 601. At this time, the second threaded head 612 presses against the plug 607, and the plug 607 presses against the spring 606, causing the spring 606 to undergo elastic deformation. Simultaneously, the plug 607 drives the rectangular rod 604 to move along the rectangular hole 610. The rectangular hole 610 and the rectangular rod 604 cooperate with each other to achieve the action of the plug 607. 07. The restriction of the position of the first threaded head 608 prevents the plug 607 and the first threaded head 608 from rotating, thereby causing the first threaded head 608 to move out of the storage hole 609, so that the exposed first threaded head 608 is screwed into another short post 601, so that the first threaded head 608 on the other short post 601 is exposed outside the storage hole 609, and so on, to complete the assembly of multiple short posts 601. This allows for the selection of an appropriate number of short posts 601 according to the length of the belt conveyor, eliminating the need to produce straightening rods 6 of different lengths, and achieving universality.

[0039] See Figures 8-12 An internal thread cap 603 is threaded onto the first threaded head 608 inside a short post 601 away from the cylindrical head 602. The outer diameter of the internal thread cap 603 is the same as the outer diameter of the short post 601. After the multiple short posts 601 are connected, the internal thread cap 603 is screwed onto the first threaded head 608 exposed in the short post 601 away from the cylindrical head 602. At this time, the internal thread cap 603 provides protection for the first threaded head 608.

[0040] See Figures 8-12A connecting ring 605 is fixedly connected to the end of the spring 606 away from the plug 607. The connecting ring 605 is glued to the innermost side of the threaded hole 611. The connecting ring 605 is sleeved on the rectangular rod 604. The end of the spring 606 away from the connecting ring 605 is fixedly connected to the plug 607. The design of the connecting ring 605 makes it easy to restrict one end of the spring 606 to the innermost side of the threaded hole 611. With the support of the spring 606, the plug 607 is flush with the open end of the threaded hole 611. At this time, the plug 607 seals the threaded hole 611, preventing small debris from entering the threaded hole 611. At the same time, with the support of the spring 606, the first threaded head 608 is placed in the storage hole 609, which plays a role in hiding and protecting the first threaded head 608, and preventing the threads on the first threaded head 608 from being damaged due to bumps or other reasons during storage or transportation.
