Description

Technical Field

[0001] This utility model relates to the field of glass conveying technology, and in particular to a glass conveying roller structure and a conveying support. Background Technology

[0002] The glass conveyor roller structure and conveyor support are core conveying components in the entire glass production and processing process. They can be defined as: a mechanical assembly that uses the conveyor support as a mounting carrier and achieves stable and directional conveying of glass sheets through the rotation of several sets of conveyor rollers. Specifically, the conveyor support, as the load-bearing foundation, is mostly constructed from welded or assembled metal profiles to form a stable frame structure used to fix the conveyor rollers and drive components. Its height and span can be adjusted according to production needs. The conveyor roller structure includes the roller body, shaft, bearings, and connecting components. The roller body material must possess both hardness and wear resistance; common materials include rubber-coated metal wheels and ceramic wheels to avoid scratching the glass surface. The cooperation between the shaft and bearings ensures smooth roller rotation.

[0003] The belt-driven transverse conveyor roller structure widely used in current glass production has revealed significant defects in practical use. The core problem lies in the difficulty of disassembling and replacing the conveyor rollers, severely impacting production efficiency and maintenance convenience. Existing belt-driven transverse conveyor rollers mostly employ an integrated shaft design. The roller shaft core and the conveyor support shaft are rigidly fixed to the shaft by welding or multiple sets of bolts. The drive belt is tightly fitted to the roller via a tensioner pulley, forming a transmission connection. When the conveyor rollers experience surface wear, rubber aging, or bearing jamming due to long-term use, operators must first remove the external drive belt, then unscrew the bolts fixing the shaft support one by one. Some welded structures even require cutting tools to separate the roller from the support, making the entire disassembly process cumbersome and complex. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a glass conveying roller structure and a conveying support to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a glass conveying roller structure and a conveying bracket, including a lifting frame. Several linearly arrayed L-shaped brackets are fixedly connected to both sides of the lifting frame. A U-shaped mounting frame is fixedly installed at the top of each L-shaped bracket. A horizontally arranged belt-driven conveying roller is inserted between every two paired U-shaped mounting frames. A sliding groove is formed through one side of each U-shaped mounting frame, and two drive plates are slidably connected inside the groove. A bidirectional lead screw is rotatably connected to one side of each U-shaped mounting frame via a bearing, and both drive plates are threadedly connected to the bidirectional lead screw. Each drive plate has two L-shaped connecting plates fixedly connected to one side. A pressure plate is fixedly connected between the tops of the two paired L-shaped connecting plates. A locking pin is fixedly connected to the side of the pressure plate near the U-shaped mounting frame. Both locking pins pass through the U-shaped mounting frame and engage with the belt-type conveyor rollers. The machine frame is also fixedly installed on the ground. Two symmetrically arranged hydraulic cylinders are fixedly connected inside the machine frame. The tops of the drive rods of the two hydraulic cylinders are fixedly connected to the lifting frame. Several linear arrays of conveyor shafts are rotatably connected to the top of the machine frame through bearings. The several conveyor shafts and several belt-type conveyor rollers are arranged alternately.

[0007] Preferably, from any of the above solutions, locking holes are provided on both the left and right sides of the belt-type conveyor roller, and the two locking pins pass through the U-shaped mounting frame and are engaged with the belt-type conveyor roller through the locking holes.

[0008] Preferably, in any of the above solutions, two connecting holes are provided on both the left and right sides of the U-shaped mounting frame, and the L-shaped connecting plate is slidably connected to the U-shaped mounting frame through the connecting holes.

[0009] Preferably, one side of the drive plate has a threaded hole, and both drive plates are threadedly connected to a bidirectional lead screw through the threaded hole.

[0010] Preferably, one end of the conveying shaft and the drive shaft end of the belt-driven conveyor roller are both fixedly connected to pulleys, and the pulleys are all driven by a motor belt structure.

[0011] Preferably, in any of the above solutions, limit grooves are provided on both the front and rear sides of the frame, and a vertically arranged limit rod is fixedly connected inside each limit groove, and the horizontal part of the L-shaped bracket is slidably connected to the limit rod.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] 1. Enables rapid disassembly and replacement of conveyor rollers, improving maintenance convenience and production efficiency. When a belt-driven conveyor roller needs replacement due to wear or failure, first loosen the connection between the motor belt structure and the pulley. Then, rotate the double-acting screw on one side of the U-shaped mounting frame. This rotates the threaded hole, causing the two drive plates to slide in opposite directions along the groove. The drive plates, through the L-shaped connecting plate, pull the pressure plate away from the belt-driven conveyor roller, allowing the locking pin to be pulled out of the locking hole of the belt-driven conveyor roller, thus releasing the fixation. Then, directly pull the belt-driven conveyor roller out of the paired U-shaped mounting frame to complete the disassembly. When installing a new roller, insert both ends into the U-shaped mounting frame. Rotate the double-acting screw in the opposite direction to reset the drive plate and the pressure plate. The locking pin passes through the connecting hole of the U-shaped mounting frame and inserts into the locking hole for quick fixation. Finally, reconnect the motor belt structure. This design eliminates the need for welding, cutting, or disassembling multiple sets of bolts, significantly simplifying the replacement process, reducing downtime for maintenance, lowering the labor intensity of operators, and ensuring continuous production.

[0014] 2. Enhanced conveying stability and height adjustment flexibility to adapt to diverse production needs. During glass conveying, the hydraulic cylinder within the frame drives the lifting frame to rise and fall, causing the L-shaped bracket to slide along the limit rod in the limit groove. This precisely adjusts the height of the belt-driven conveyor rollers, ensuring they cooperate with the conveyor shaft to form a stable conveying surface and prevent glass tilting or jamming. The rigid connection between the L-shaped bracket and the U-shaped mounting frame, along with the stable drive of the drive plate by the bidirectional screw, ensures a tight engagement between the locking pin and the locking hole, preventing displacement of the belt-driven conveyor rollers during operation and guaranteeing conveying accuracy. The motor belt structure synchronously drives the conveyor shaft and belt-driven conveyor rollers through the pulleys, ensuring even force distribution and smooth conveying of the glass. The lifting adjustment function can adapt to glass of different thicknesses and the height requirements of various processing stages without replacing the entire bracket, improving equipment versatility. The coordinated action of all components ensures stable and safe glass conveying while enhancing the equipment's adaptability to production scenarios and improving production flexibility.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0023] like Figures 1 to 6 As shown, a glass conveying roller structure and conveying bracket include a lifting frame 1. Several linearly arrayed L-shaped brackets 2 are fixedly connected to both sides of the lifting frame 1. A U-shaped mounting frame 3 is fixedly installed at the top of each L-shaped bracket 2. A horizontally arranged belt-driven conveying roller 4 is inserted between every two paired U-shaped mounting frames 3. A sliding groove 5 is formed through one side of each U-shaped mounting frame 3. Two drive plates 6 are slidably connected inside the sliding groove 5. The dimensions of the sliding groove 5 and the drive plates 6 are adapted to each other, allowing the drive plates 6 to slide smoothly inside the sliding groove 5. Simultaneously, the horizontal part of the L-shaped connecting plate 8 serves as a guide, preventing the drive plates 6 from shifting inside the sliding groove 5. One side of the U-shaped mounting frame 3 is rotatably connected via a bearing. The system includes a bidirectional lead screw 7, two drive plates 6 that are threadedly connected to the bidirectional lead screw, two L-shaped connecting plates 8 fixedly connected to one side of each drive plate 6, a pressure plate 9 fixedly connected between the tops of the two paired L-shaped connecting plates 8, a locking pin 10 fixedly connected to the side of the pressure plate 9 near the U-shaped mounting frame 3, and both locking pins 10 penetrating the U-shaped mounting frame 3 and engaging with the belt-type conveyor rollers 4. It also includes a frame 14 fixedly installed on the ground, with two symmetrically arranged hydraulic cylinders 19 fixedly connected inside the frame 14. The tops of the drive rods of the two hydraulic cylinders 19 are fixedly connected to the lifting frame 1. The top of the frame 14 is rotatably connected to several linearly arrayed conveyor shafts 15 via bearings, with the several conveyor shafts 15 and several belt-type conveyor rollers 4 arranged alternately.

[0024] As an optional technical solution of this utility model, locking holes 11 are provided on both the left and right sides of the belt-type conveyor roller 4. Two locking pins 10 pass through the U-shaped mounting frame 3 and are engaged with the belt-type conveyor roller 4 through the locking holes 11. The locking holes 11 on the left and right sides of the belt-type conveyor roller 4 and the locking pins 10 are precisely matched, so that the locking pins 10 can be stably engaged in the inside of the roller to form an axial limit, preventing the belt-type conveyor roller 4 from shifting under rotation or glass impact. At the same time, the fixing effect is strengthened by the hole pin engagement method, ensuring the stability of the roller position during the conveying process and improving the smoothness of glass conveying.

[0025] As an optional technical solution of this utility model, two connecting holes 12 are opened through both the left and right sides of the U-shaped mounting frame 3. The L-shaped connecting plate 8 is slidably connected to the U-shaped mounting frame 3 through the connecting holes 12. The connecting holes 12 of the U-shaped mounting frame 3 provide sliding guidance for the L-shaped connecting plate 8, ensuring that the L-shaped connecting plate 8 drives the pressure plate 9 and the locking pin 10 to move along a fixed trajectory, avoiding the offset when the locking pin 10 is connected to the locking hole 11, improving the accuracy and smoothness of the locking operation, and at the same time limiting the shaking of the L-shaped connecting plate 8 and enhancing the structural stability.

[0026] As an optional technical solution of this utility model, a threaded hole 13 is provided through one side of the drive plate 6. Both drive plates 6 are threadedly connected to the bidirectional lead screw through the threaded hole 13. The threaded hole 13 of the drive plate 6 and the bidirectional lead screw form a stable threaded connection, so that when the bidirectional lead screw rotates, it can drive the two drive plates 6 to slide synchronously in opposite directions or relative to each other, ensuring that the locking pins 10 on both sides act simultaneously, realizing symmetrical locking and unlocking of the belt-type transmission roller 4, ensuring uniform locking force, and improving the convenience of operation.

[0027] As an optional technical solution of this utility model, pulleys 16 are fixedly connected to one end of the conveyor shaft 15 and the drive shaft end of the belt-driven conveyor roller 4. Several pulleys 16 are driven by a motor belt structure, which uses a single drive motor as its power source. The output shaft end of the motor is fixedly connected to a drive pulley, which is simultaneously wound around the grooves of seven pulleys 16 via an annular transmission belt. The friction between the belt and the grooves transmits the motor torque to each pulley 16, thereby driving the conveyor shaft 15 and the belt-driven conveyor roller 4. Synchronous operation: The hydraulic cylinder 19 inside the frame 14 drives the lifting frame 1 to rise and fall, and the height of the belt-driven conveyor roller 4 can be flexibly adjusted to match the conveyor shaft 15 to form a stable conveying surface, meeting the height requirements of glass of different thicknesses and various processing stages; the conveyor shaft 15 and the belt-driven conveyor roller 4 are staggered, expanding the support range of the glass and preventing damage to the glass due to uneven force. The conveyor shaft 15 and the belt pulley 16 of the belt-driven conveyor roller 4 are synchronously driven by a motor belt structure to ensure that the two rotate at the same speed, so that the glass is subjected to uniform force and moves smoothly during the conveying process, avoiding scratches or displacement of the glass due to speed differences; the unified drive method simplifies the transmission structure and reduces the difficulty of equipment maintenance.

[0028] As an optional technical solution of this utility model, limit grooves 17 are provided on both the front and rear sides of the frame 14. A vertically arranged limit rod 18 is fixedly connected inside each limit groove 17. The horizontal part of the L-shaped bracket 2 is slidably connected to the limit rod 18. The limit rod 18 in the limit groove 17 of the frame 14 is slidably engaged with the L-shaped bracket 2. The horizontal part of the L-shaped bracket 2 is provided with a through hole that matches the limit rod 18. The engagement of the limit rod 18 and the through hole achieves a guiding effect, forming a vertical guide for the lifting action of the lifting frame 1, preventing the lifting frame 1 from tilting or shaking during movement, ensuring accurate height adjustment of the belt-type conveyor roller 4, ensuring the horizontal stability of glass conveying, and enhancing the load-bearing capacity of the overall structure.

[0029] A glass conveying roller structure and conveying support, the working principle of which is as follows:

[0030] 1): When the belt-driven conveyor roller 4 is worn or malfunctions and needs to be replaced, first loosen the connection between the motor belt structure and the pulley 16, then rotate the double-acting screw 7 on one side of the U-shaped mounting frame 3, and drive the two drive plates 6 to slide in the opposite direction along the slide groove 5 through the threaded hole 13.

[0031] 2): The drive plate 6 pulls the pressure plate 9 away from the belt-type conveyor roller 4 through the L-shaped connecting plate 8, so that the locking pin 10 is pulled out from the locking hole 11 of the belt-type conveyor roller 4 and the fixation is released.

[0032] 3): Then, directly pull the belt-driven conveyor roller 4 out of the paired U-shaped mounting frames 3 to complete the disassembly. When installing the new roller, insert both ends into the U-shaped mounting frames 3, rotate the bidirectional lead screw 7 in the opposite direction to make the drive plate 6 drive the pressure plate 9 to reset, and insert the locking pin 10 through the connecting hole 12 of the U-shaped mounting frame 3 into the locking hole 11 to achieve quick fixation.

[0033] In summary, this glass conveyor roller structure and conveyor bracket enable quick disassembly and replacement of the conveyor rollers, improving maintenance convenience and production efficiency. When the belt-driven conveyor roller 4 is worn or malfunctioning and needs replacement, first loosen the connection between the motor belt structure and the pulley 16, then rotate the double-acting screw 7 on one side of the U-shaped mounting frame 3. Through the threaded hole 13, drive the two drive plates 6 to slide in the opposite direction along the slide groove 5. The drive plates 6 pull the pressure plate 9 away from the belt-driven conveyor roller 4 through the L-shaped connecting plate 8, causing the locking pin 10 to be pulled out of the locking hole 11 of the belt-driven conveyor roller 4, thus releasing the fixation. Then, directly pull the belt-driven conveyor roller 4 out of the paired U-shaped mounting frames 3 to complete the disassembly. When installing a new roller, insert both ends into the U-shaped mounting frame 3, rotate the double-acting screw 7 in the opposite direction to make the drive plate 6 drive the pressure plate 9 to reset, and the locking pin 10 passes through the connecting hole 12 of the U-shaped mounting frame 3 and inserts into the locking hole 11 to achieve quick fixation. Finally, reconnect the motor belt structure. This design eliminates the need for welding, cutting, or disassembling multiple bolt sets, significantly simplifying the replacement process, reducing downtime for maintenance, lowering operator workload, and ensuring production continuity. It enhances conveying stability and height adjustment flexibility, adapting to diverse production needs. During glass conveying, the hydraulic cylinder 19 within the frame 14 drives the lifting frame 1 to rise and fall, causing the L-shaped bracket 2 to slide along the limiting rod 18 within the limiting groove 17. This precisely adjusts the height of the belt-driven conveyor roller 4, ensuring it mates with the conveyor shaft 15 to form a stable conveying surface and prevent glass tilting or jamming. The rigid connection between the L-shaped bracket 2 and the U-shaped mounting frame 3, along with the stable drive of the bidirectional lead screw 7 to the drive plate 6, ensures a tight engagement between the locking pin 10 and the locking hole 11, preventing displacement of the belt-driven conveyor roller 4 during operation and guaranteeing conveying accuracy. The motor belt structure synchronously drives the conveyor shaft 15 and the belt-driven conveyor roller 4 via the pulley 16, ensuring uniform force on the glass and smooth conveying. The lifting adjustment function can adapt to glass of different thicknesses and the height requirements of various processing stages without requiring replacement of the entire frame, thus improving equipment versatility. The coordinated operation of all components not only ensures the smooth and safe transport of glass, but also enhances the equipment's adaptability to production scenarios and improves production flexibility.
