Description

Technical Field

[0001] This utility model relates to a belt conveyor, specifically a liftable belt conveyor. Background Technology

[0002] The manufacturing process of copper-clad laminates can be simply understood as follows: prepreg and copper foil are cut to specific sizes as needed, stacked in a certain order, and then placed into a hot press for hot pressing. During the manufacturing process, the stacked prepreg and copper foil are usually exchanged with the base plate to achieve continuous cyclic manufacturing of copper-clad laminates.

[0003] In existing technologies, the stacked plates to be pressed and the base plates are often exchanged manually. This production method is obviously outdated and inefficient. A further technological advancement involves transporting the stacked plates to be pressed via a stacking lifting platform to the upper layer of a double-layer conveyor, and then the base plates are transported via the lower layer of the double-layer conveyor to the stacking lifting platform.

[0004] The existing lifting platform has a fixed conveying area at the top, while the product specifications are different. If the product area is large during conveying, the lifting platform cannot support and convey the entire product, and part of the product is suspended outside, which is easy to be accidentally touched and collided with, resulting in product damage. Or, due to accidental touch, the product may be deviated, affecting the normal conveying of the product, or the product may be damaged due to collision. Utility Model Content

[0005] The purpose of this utility model is to provide a liftable belt conveyor, which solves the problems of limited conveying area and inability to adapt to products of different specifications in the existing technology.

A first conveyor and a second conveyor are provided on the top surface of the top plate that are parallel to each other. A first drive roller and a second drive roller that are coaxially arranged are respectively provided on the same side of the first conveyor and the second conveyor. A drive motor for driving the first drive roller and the second drive roller to rotate synchronously is provided on the side wall of the top plate. The second conveyor can move relative to the first conveyor in the width direction.

[0007] As a further preferred technical solution of this utility model; a first crossbeam is provided between the lower sides of the two first scissor arms, a second crossbeam is provided between the upper sides of the two second scissor arms, and two drive cylinders are provided between the first crossbeam and the second crossbeam. The fixed end of the drive cylinder is rotatably connected to the first crossbeam, and the cylinder rod end of the drive cylinder is rotatably connected to the second crossbeam. The lower end of the first scissor arm can reciprocate relative to the base toward the lower end of the second scissor arm.

[0008] As a further preferred technical solution of this utility model, a connecting column is provided at one end of the first driving roller that is close to the second driving roller, and a fixed cylinder is provided at the end of the second driving roller that is sleeved on the side wall of the connecting column and can move axially relative to the connecting column.

Detailed Implementation

[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0015] like Figure 1-2 As shown, a liftable belt conveyor includes a base 1 with two parallel scissor structures on it. Each scissor structure includes a first scissor arm 11 and a second scissor arm 12 that intersect each other. This scissor structure is existing technology. The first scissor arm 11 and the second scissor arm 12 are cross-connected to form the scissor structure. The first scissor arm 11 and the second scissor arm 12 can rotate relative to their connection point, thus achieving the lifting and lowering action of a top plate 2. A top plate 2 is located on top of the scissor structures above the base 1. The top plate 2 can move up and down under the support of the scissor structures. A first conveyor 3 and a second conveyor 4, arranged parallel to each other, are provided on the top surface of the plate 2. Both the first conveyor 3 and the second conveyor 4 are existing technologies, consisting of a drive roller, multiple driven rollers, and a conveyor belt covering the outer walls of the drive roller and driven rollers. They can transport products. The lifting movement of the top plate 2 drives the lifting movement of the first conveyor 3 and the second conveyor 4 to facilitate the transfer of products to different conveyor lines. A first drive roller 31 and a second drive roller 41, arranged coaxially, are respectively provided on the same side of the first conveyor 3 and the second conveyor 4. The first drive roller 31 and the second drive roller 41 serve as driving components for the first conveyor 3 and the second conveyor 4, respectively, to perform conveying operations. A drive motor 21 is provided on the side wall of the top plate 2 to drive the first drive roller 31 and the second drive roller 41 to rotate synchronously. The drive motor 21 is existing technology and can drive the first drive roller 31 to rotate, thereby driving the driven roller in the first conveyor 3 to rotate, thus realizing the conveying function of the first conveyor 3. The first drive roller 31 and the second drive roller 41 are coaxially connected, so that when the drive motor 21 drives the first drive roller 31 to rotate, the second drive roller 41... The two drive rollers 41 can be driven to rotate synchronously to realize the conveying function of the second conveyor 4. The second conveyor 4 can move relative to the first conveyor 3 in the width direction. The second conveyor 4 can move a specified distance relative to the first conveyor 3 in the width direction to realize the adjustment of the conveying area and maintain the conveying action of the first conveyor 3 and the second conveyor 4, thereby adapting to the conveying needs of products of different specifications, avoiding parts of the product being suspended outside, being accidentally touched or collided, causing product damage, or being deviated due to accidental touch, affecting the normal conveying of the product, or being damaged due to collision.

[0016] like Figure 1-2As shown, a first crossbeam 13 is provided between the lower sides of the two first scissor arms 11, and a second crossbeam 14 is provided between the upper sides of the two second scissor arms 12. The two ends of the first crossbeam 13 are connected to the lower sides of the two first scissor arms 11, and the two ends of the second crossbeam 14 are connected to the upper sides of the two second scissor arms 12, respectively, thus supporting the two first scissor arms 11 and the two second scissor arms 12 and strengthening the structural strength of the scissor arm structure. Two drive cylinders 15 are provided between the first crossbeam 13 and the second crossbeam 14. The two drive cylinders 15 are arranged parallel to each other and operate synchronously. The fixed end of the drive cylinder 15 is rotatably connected to the first crossbeam 13, and the cylinder rod end of the drive cylinder 15 is rotatably connected to the second crossbeam 14. The lower end of the first scissor arm 11 can be oriented relative to the base 1 towards the first crossbeam 14. The lower ends of the two scissor arms 12 reciprocate. The lower end of the first scissor arm 11 is equipped with rollers and can move horizontally along the edge of the base 1 toward the lower end of the second scissor arm 12. When the top plate 2 is driven to lift, two drive cylinders 15 are activated. The cylinder rods of the two drive cylinders 15 extend and retract synchronously and drive the two second scissor arms 12 to move synchronously through the second crossbeam 14. The drive cylinders 15 deflect with the displacement of the second scissor arms 12 through the rotational connection with the first crossbeam 13 and the second crossbeam 14, adapting to the movement changes of the scissor structure. The lower end of the first scissor arm 11 moves closer to or further away from the second scissor arm 12 on the base 1, thereby realizing the lifting and lowering drive of the top plate 2, and then changing the conveying height of the first conveyor 3 and the second conveyor 4 to facilitate the transfer and conveying of products.

[0017] like Figure 2-3 As shown, a connecting post 33 is provided at one end of the first drive roller 31 that is close to the second drive roller 41. A fixed cylinder 42, sleeved on the side wall of the connecting post 33 and axially movable relative to the connecting post 33, is provided at the end of the second drive roller 41. The fixed cylinder 42 is fixedly connected to the end of the second drive roller 41. One end of the connecting post 33 can be welded to the end of the first drive roller 31, or it can be fixed with bolts or tightly fitted. The other end of the connecting post 33 passes through the inner side of the fixed cylinder 42, allowing the connecting post 33 to move axially relative to the fixed cylinder 42. Multiple axially arranged strip grooves 421 are provided on the inner wall of the fixed cylinder 42. A limiting part 422 is formed at one end of the upper part facing the first drive roller 31. A protrusion 331 that cooperates with the strip groove 421 is provided on the end side wall of the connecting column 33. The cooperation between the protrusion 331 and the strip groove 421 restricts the circumferential rotation between the connecting column 33 and the fixed cylinder 42, and keeps the axial movement of the connecting column 33 relative to the fixed cylinder 42 stable. At the same time, the limiting part 422 formed at the end of the strip groove 422 can limit the movement range of the connecting column 33. The limiting part 422 and the protrusion 331 cooperate to form a blocking structure to prevent the connecting column 33 from moving excessively and detaching from the fixed cylinder 42.

[0018] like Figure 2-3As shown, a rotating cylinder 35 is sleeved on the outer wall of the end of the first drive roller 31. An annular slider 351, which slides against an annular groove 311 on the outer wall of the first drive roller 31, is provided on the inner side of one end of the rotating cylinder 35. One end of the rotating cylinder 35 is sleeved on the outer wall of the first drive roller 31 and is rotatably connected to the outer wall of the first drive roller 31 through the connection and sliding engagement of the annular slider 351 and the annular groove 311. It can rotate around an axis on the outer wall of the first drive roller 31. The other end of the rotating cylinder 35 is sleeved on the outer wall of the fixed cylinder 42 and screwed to the outer wall of the fixed cylinder 42. The rotating cylinder 35 is connected by a threaded connection to the outer wall of the fixed cylinder 42, and the groove 421 and protrusion 331 cooperate to allow the rotating cylinder 35 to rotate, thereby driving the fixed cylinder 42 to move axially relative to the connecting column 33. This, in turn, drives the second drive roller 41 and the second conveyor 4 to move along the width direction, thus enabling the adjustment of the movement of the second conveyor 4. The rotating cylinder 35 can be manually driven to rotate, or it can be connected to an external drive motor via a transmission belt for electric drive. It can also be adjusted according to product specifications. The distance between the first conveyor 3 and the second conveyor 4 changes the conveying area of ​​the product. At the same time, the threaded connection between the rotating cylinder 35 and the fixed cylinder 42 can lock the position of the second conveyor 4 after it moves, preventing the second conveyor 4 from loosening or shifting during the conveying process. The top plate 2 has a strip slot 22 corresponding to the bottom of the second conveyor 4. The strip slot 22 has multiple linear guide rails 23 arranged along the width direction of the second conveyor 4 and fixedly connected to the bottom of the top plate 2. The linear guide rails 23 are existing technology and will not be described in detail here. The linear guide rails 23 are arranged in the strip slot 22 to facilitate the connection to the bottom of the second conveyor 4. Multiple linear guide rails 23 and strip slots 22 can be set as needed and arranged parallel to each other. The movable part of the linear guide rail 23 is connected to the bottom of the second conveyor 4, and the two ends of the fixed part of the linear guide rail 23 are connected and fixed to the bottom of the top plate 2. When driving the second conveyor 4 to move, the linear guide rail 23 assists in supporting the second conveyor 4 to slide along the linear guide rail 23, reducing friction interference, making the movement of the second conveyor 4 smoother and improving the adjustment efficiency.

[0019] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
