Description

Technical Field

[0001] This invention belongs to the field of conveying equipment, and specifically relates to a tension-type anti-static packaging conveying device. Background Technology

[0002] Modern conveyor packaging equipment is a key component of automated production lines, widely used in food, pharmaceutical, logistics, and manufacturing industries. The core function of this type of equipment is to achieve continuous material transport and packaging through a highly efficient and stable conveyor belt system. During transport, the conveyor belt needs to be kept taut to ensure it is always in optimal working condition, thus preventing slippage, deviation, or slack during packaging and transport, thereby improving production efficiency and system reliability.

[0003] Chinese Patent Application No. 202421524539.2 discloses a conveying mechanism for an automatic corrugated cardboard stacking machine, including a base, a conveyor frame installed on the inner side of the base, an angle adjustment mechanism for driving the conveyor frame to rotate on the base, a belt conveyor mechanism installed on the conveyor frame, and a tensioning mechanism for tensioning the belt conveyor mechanism installed on the conveyor frame. The tensioning mechanism includes: a rotating shaft, a third gear, a third motor, a support shaft, a fourth gear, a connecting rod, and a tensioning roller. The rotating shaft is rotatably connected to the conveyor frame. This patent uses the rotation of the fourth gear to drive the connecting rod to slide downward in an arc-shaped groove, which in turn drives the tensioning roller to move downward. The tensioning roller then compresses and tensions the conveyor belt, preventing it from becoming loose or slipping. This makes tensioning the conveyor belt convenient and prevents it from becoming loose or slipping.

[0004] However, in existing technologies, the timing of conveyor belt tensioning relies solely on worker experience. Starting the tensioning device and process only after deeming the belt in need of tension easily leads to misjudgments or delays in the tensioning operation. This can result in problems like slackness, slippage, or misalignment of the conveyor equipment without timely tension adjustment. Furthermore, the fixed tension adjustment range cannot accommodate the varying levels of tension required for transporting different goods or packaging. Summary of the Invention

[0005] This invention achieves automatic tensioning of the conveyor belt in a conveying device through the cooperation of a compression rod, a moving roller, an adjusting roller, an inflation assembly, a pressing roller, a corner roller, a conveyor roller, and a conveyor belt. When conveying goods with different tension sensitivity requirements, such as electronic products or plastic products, this invention can dynamically optimize the tension according to load changes, making the conveyor belt tension adjustable to adapt to the required tension of different goods or packaging. The conveyor roller, the orbital roller in the pressing roller, the adjusting roller, and the corner roller, which are in direct contact with the conveyor belt, are all made of conductive metal materials, which serves to prevent static electricity.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tension-type antistatic packaging conveyor includes an inflation assembly, a pressure roller, an adjusting roller, a corner roller, and multiple conveyor rollers, each mounted on a support via positioning plates. One end of a compression rod is fixedly connected to one of the positioning plates, and the other end is rotatably connected to a moving roller. Multiple conveyor belts sequentially loop around the multiple conveyor rollers, moving rollers, and corner rollers, passing between the moving rollers and the adjusting rollers. A first motor on the support is driven by the conveyor rollers. Meshing gears are fitted and fixed onto the moving rollers and the adjusting rollers. The inflation assembly is driven by the adjusting rollers. When the adjusting rollers rotate, air pressure accumulates within the inflation assembly, activating a second motor electrically connected to it once a set value is reached. The pressure roller is driven by the second motor. When the pressure roller rotates, it presses against the conveyor belts, separating the moving rollers from the adjusting rollers.

[0008] Furthermore, the inflation assembly includes a first connecting rod, a second connecting rod, and an inflation rod that are rotatably connected in sequence. One end of the first connecting rod is eccentrically rotatably connected to the end face of the adjusting roller. One end of the inflation rod is slidably placed inside the inflation cylinder. The inflation cylinder is connected to the air pressure sensor through an inflation tube.

[0009] Furthermore, the inflation cylinder has an inlet valve and an outlet valve. When the inflation rod slides outward, the inlet valve opens and the outlet valve closes, allowing the inflation cylinder to inflate. When the inflation rod slides inward, the inlet valve closes and the outlet valve opens, allowing the gas in the inflation cylinder to enter the inflation pipe.

[0010] Furthermore, the pressure sensor is electrically connected to the second motor, and the pressure sensor is configured to transmit an electrical signal to the second motor when the air pressure reaches a set value, thereby starting the second motor.

[0011] Furthermore, the pressing roller includes a rotating roller and a revolving roller connected by a bent rod, the rotating roller being driven by the second motor. The revolving roller can rotate around the rotating roller in the direction of the conveyor belt.

[0012] Furthermore, the compression rod includes an interconnected rod body and a fixing block, the fixing block being fixedly connected to a positioning plate, and the fixing block being rotatable to adjust the angle of the rod body relative to the horizontal plane.

[0013] Furthermore, the moving roller has multiple first gears, which are arranged alternately along the length of the moving roller between the conveyor belts. The adjusting roller has multiple second gears, which are arranged alternately along the length of the adjusting roller.

[0014] Furthermore, the bracket has a side plate on which the first motor is fixed.

[0015] Furthermore, the support includes two crossbeams and multiple legs, with each conveyor roller rotatably connected between the two crossbeams. One end of each leg is connected to the crossbeam, and the other end rests on the ground.

[0016] Furthermore, the crossbeam has multiple threaded holes along its length, and the positioning plate is fixed to a set position on the crossbeam by means of threaded screws.

[0017] Furthermore, the bracket, the conveying roller, the moving roller, the corner roller, the pressing roller, the compression rod, and the positioning plate are all made of metal.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This invention can realize automatic tensioning of the conveyor belt, ensuring the high efficiency and stability of the conveying device, and avoiding the problem of packaging slipping or running off-center on the conveyor belt; This invention realizes the function of automatic tensioning of the conveyor belt of the conveying equipment through the cooperation of the compression rod, the moving roller, the adjusting roller, the inflation component, the pressing roller, the corner roller, the conveying roller and the conveyor belt. Because the conveyor belt passes around the moving roller, the corner roller and multiple conveying rollers in sequence to form a closed loop and is tensioned, the moving roller is subjected to the tension of the conveyor belt, and the compression rod connected to the moving roller is compressed. At this time, the moving roller will be pushed towards the adjusting roller; As the conveying device is working, when the conveyor belt becomes loose, the moving roller will move towards the adjusting roller under the thrust of the compression rod until the gears on the moving roller and the adjusting roller are engaged. When the rollers approach each other and can mesh, the moving rollers will drive the adjusting rollers to rotate together. The rotation of the adjusting rollers will accumulate air inside the inflation assembly until the air pressure inside the inflation assembly reaches the set pressure value. Then, an electrical signal will be transmitted to the second motor. The second motor will start rotating and drive the pressure rollers to rotate. As the pressure rollers rotate, they will press down on the conveyor belt a certain distance. At this time, the tension on the moving rollers will increase, and the tension will be opposite to the thrust of the compression rod on the moving rollers. The compression rod will contract, and the moving rollers will move away from the adjusting rollers. The adjusting rollers will then stop rotating, completing one tensioning cycle of the conveyor belt. The automatic tensioning of the conveyor belt ensures the high efficiency and stability of the conveying device, thereby avoiding the problem of packaging slipping or deviating on the conveyor belt, improving production efficiency and the reliability of the conveying system.

[0020] (2) When conveying goods with different requirements for tension sensitivity, such as electronic products or plastic products, the present invention can dynamically optimize the tension according to the load change, so that the tension of the conveyor belt can be adjusted to adapt to the required tension of the conveyor belt for conveying different goods or packaging. This invention uses positioning plates of varying lengths to attach compression rods, moving rollers, adjusting rollers, inflation components, pressing rollers, corner rollers, and conveyor rollers to a support frame. The positioning plates are fixed to the crossbeam with threaded screws and can be adjusted according to the threaded holes on the crossbeam, thus achieving positioning and spacing adjustment between components. By selecting positioning plates of different lengths and changing their fixed points on the crossbeam, the initial center distance between the moving and adjusting rollers can be adjusted. For packaging conveyors requiring high conveyor belt tension, the initial center distance between the moving and adjusting rollers can be reduced, triggering the tensioning function even with a slight decrease in conveyor belt tension. For packaging conveyors with lower conveyor belt tension requirements, the initial center distance can be increased, reducing the trigger frequency of the conveyor belt tensioning function, decreasing wear, and extending the device's lifespan. This makes the conveyor belt tension adjustable to adapt to the different conveyor belt tension requirements of various goods or packaging.

[0021] (3) In this invention, the conveying rollers, the orbiting rollers, the adjusting rollers, and the corner rollers that are in direct contact with the conveyor belt are all made of conductive metal materials. Each of these rollers is attached to a support frame via a positioning plate made of the same metal material. The support frame is in direct contact with the ground, thus allowing the static electricity generated by the conveyor belt during the packaging process to be directly transferred to the ground, providing an anti-static effect. Static electricity can attract dust or product debris from the air, leading to material contamination. The anti-static design of this device avoids this problem and is particularly suitable for packaging and conveying scenarios with high cleanliness requirements, such as those for food and pharmaceuticals. Furthermore, in flammable and explosive environments, electrostatic discharge may cause fires or explosions; the anti-static design eliminates this risk. Attached Figure Description

[0046] Example

[0047] like Figures 1-8 As shown, a tension-type antistatic packaging conveyor device includes an inflation assembly 10, a pressure roller 20, an adjusting roller 30, a corner roller 40, and multiple conveyor rollers 50, each connected to a support 70 via a positioning plate 60. One end of a compression rod 80 is fixedly connected to a positioning plate 60, and the other end is rotatably connected to a moving roller 90. Multiple conveyor belts 100 sequentially loop around the multiple conveyor rollers 50, the moving roller 90, and the corner roller 40, passing between the moving roller 90 and the adjusting roller 30. A first motor 200 on the support 70 is drive-connected to the conveyor rollers 50. Gears that mesh with each other are fitted and fixed on the moving roller 90 and the adjusting roller 30. The inflation assembly 10 is drive-connected to the adjusting roller 30. When the adjusting roller 30 rotates, air pressure accumulates in the inflation assembly 10, and upon reaching a set value, a second motor 300 electrically connected to it is activated. The pressing roller 20 is connected to the second motor 300 for transmission. When the pressing roller 20 rotates, it presses the conveyor belt 100. The moving roller 90 is separated from the adjusting roller 30.

[0048] This invention achieves automatic tensioning of the conveyor belt 100 of the conveying equipment through the cooperation of a compression rod 80, a moving roller 90, an adjusting roller 30, an inflation component 10, a pressing roller 20, a corner roller 40, a conveyor roller 50, and a conveyor belt 100. Because the conveyor belt 100 sequentially loops around the moving roller 90, the corner roller 40, and multiple conveyor rollers 50 to form a closed loop and is tensioned, the moving roller 90 is subjected to the tension of the conveyor belt 100, and the compression rod 80 connected to the moving roller 90 is compressed. At this time, the moving roller 90 will experience a pushing tendency towards the adjusting roller 30. As the conveying device operates, when the conveyor belt 100 becomes slack, the moving roller 90 will move towards the adjusting roller 30 under the pushing force of the compression rod 80 until the gears on the moving roller 90 and the adjusting roller 30 are close enough to mesh. The moving roller 90 will then drive the adjusting roller 30. The roller 30 rotates together; the rotation of the adjusting roller 30 will accumulate air inside the inflation component 10 until the air pressure inside the inflation component 10 reaches the set pressure value, and then transmit an electrical signal to the second motor 300; the second motor 300 starts to rotate and drives the pressing roller 20 to rotate. While the pressing roller 20 rotates, it will press down on the conveyor belt 100 a certain distance. At this time, the moving roller 90 is subjected to increased tension from the conveyor belt 100. The tension is opposite to the thrust of the compression rod 80 on the moving roller 90. The compression rod 80 contracts, the moving roller 90 moves away from the adjusting roller 30, and the adjusting roller 30 stops rotating, completing one tensioning of the conveyor belt 100; by automatically tensioning the conveyor belt 100, the high efficiency and stability of the conveying device are ensured, thereby avoiding the problem of packaging slipping or running off-center on the conveyor belt 100, improving production efficiency and the reliability of the conveying system.

[0049] It is worth noting that one end of the adjusting roller 30 is directly rotatably connected to the end of a positioning plate 60, while the other end of the adjusting roller 30 connected to the inflation component 10 is rotatably connected through a disc bearing 400 fixedly connected to another positioning plate 60, so that the connection point of the positioning plate 60 and the connection point of the adjusting roller 30 are far apart from each other, thus not interfering with the operation of the inflation component 10 on the end face of the adjusting roller 30.

[0050] Furthermore, the inflation assembly 10 includes a first connecting rod 101, a second connecting rod 102, and an inflation rod 103 that are rotatably connected in sequence. One end of the first connecting rod 101 is eccentrically rotatably connected to the end face of the adjusting roller 30. One end of the inflation rod 103 is slidably placed inside the inflation cylinder 104. The inflation cylinder 104 is connected to the air pressure sensor 108 through the inflation pipe 107.

[0051] Furthermore, the air cylinder 104 has an inlet valve 105 and an outlet valve 106. When the inflation rod 103 slides outward, the inlet valve 105 opens and the outlet valve 106 closes, allowing air to fill the air cylinder 104. When the inflation rod 103 slides inward, the inlet valve 105 closes and the outlet valve 106 opens, allowing the gas in the air cylinder 104 to enter the inflation pipe 107.

[0052] Furthermore, the pressure sensor 108 is electrically connected to the second motor 300. The pressure sensor 108 is configured to transmit an electrical signal to the second motor 300 when the air pressure reaches a set value, and the second motor 300 starts.

[0053] It is worth noting that the first motor 200, the second motor 300 and other electrical equipment in this invention are all powered by an external power source, and the pressure sensor in the inflation assembly 10 can monitor the pressure value and output control electrical signals. These are all existing technologies and will not be described in detail here.

[0054] Furthermore, the pressing roller 20 includes a rotating roller 202 and a revolving roller 203 connected by a bent rod 201. The rotating roller 202 is driven by the second motor 300. The revolving roller 203 can rotate around the rotating roller 202 in the direction of the conveyor belt 100.

[0055] In this invention, the bent rod 201, through its bent design, allows it to bypass the adjusting roller 30 at a higher elevation, connecting the rotating roller 202 and the revolving roller 203. This allows the bent rod 201 to swing without interference from the adjusting roller 30 when the rotating roller 202, which is connected to one end of the bent rod 201, rotates. When the bent rod 201 swings, the revolving roller 203, which is connected to the other end of the bent rod 201, moves downward toward the conveyor belt 100 until it presses down on the conveyor belt 100, causing the conveyor belt 100 to tighten again, thus achieving tensioning of the conveyor belt 100.

[0056] Furthermore, the compression rod 80 includes a rod body 801 and a fixing block 802 connected to each other. The fixing block 802 is fixedly connected to a positioning plate 60. The fixing block 802 can be rotated and adjusted to adjust the angle of the rod body 801 relative to the horizontal plane.

[0057] In this invention, since the moving roller 90 needs to be pushed towards the adjusting roller 30 by the compression rod 80 during the installation and adjustment stage, the adjustment block connected to one end of the compression rod 80 is set to be adjustable in angle, so as to facilitate accurate adjustment of the initial position of the moving roller 90 and the adjusting roller 30.

[0058] Furthermore, the moving roller 90 has multiple first gears 901, which are arranged alternately along the length of the moving roller 90 between each conveyor belt 100. The adjusting roller 30 has multiple second gears 301, which are arranged alternately along the length of the adjusting roller 30.

[0059] In this invention, the conveyor belts 100 are arranged side by side at intervals, and the multiple first gears 901 on the moving rollers 90 are arranged alternately with the conveyor belts 100 at intervals, without interfering with each other.

[0060] Furthermore, the support 70 includes two crossbeams 701 and multiple legs 702, with each conveyor roller 50 rotatably connected between the two crossbeams 701. One end of each leg 702 is connected to the crossbeam 701, and the other end rests on the ground.

[0061] Furthermore, the crossbeam 701 is provided with multiple threaded holes 703 along its length, and the positioning plate 60 is fixed in the set position of the crossbeam 701 by means of threaded screws.

[0062] This invention uses positioning plates 60 of varying lengths to connect the compression rod 80, moving roller 90, adjusting roller 30, inflation assembly 10, pressing roller 20, corner roller 40, and conveying roller 50 to a bracket 70. The positioning plates 60 are fixed to the crossbeam 701 with threaded screws, and can be adjusted according to the threaded holes 703 on the crossbeam 701. This allows for the positioning of the components and adjustment of the spacing between them. Therefore, by selecting positioning plates 60 of different lengths, the fixing points of the positioning plates 60 on the crossbeam 701 can be changed. This allows for adjustment of the initial center distance between the moving roller 90 and the adjusting roller 30. For packaging conveying with high tension requirements of the conveyor belt 100, the initial center distance between the moving roller 90 and the adjusting roller 30 can be reduced, thus triggering the tensioning function when the tension of the conveyor belt 100 decreases slightly. For packaging conveying with low tension requirements of the conveyor belt 100, the initial center distance between the moving roller 90 and the adjusting roller 30 can be increased, thus reducing the triggering frequency of the conveyor belt 100 tensioning function, reducing wear, and extending the service life of the device. When conveying goods with different tension sensitivity requirements, such as electronic products or plastic products, the tension can be dynamically optimized according to load changes, making the tension of the conveyor belt 100 adjustable to adapt to the tension requirements of different goods or packaging.

[0063] Furthermore, the support 70, conveying roller 50, moving roller 90, corner roller 40, pressing roller 20, compression rod 80 and positioning plate 60 are all made of metal.

[0064] In this invention, the conveyor rollers 50, the orbital roller 203 of the pressing rollers 20, the adjusting rollers 30, and the corner rollers 40, which are in direct contact with the conveyor belt 100, are all made of metal. Each of these rollers is attached to a support 70 via a positioning plate 60, also made of metal. The support 70 is in direct contact with the ground, allowing static electricity generated by the conveyor belt 100 during the packaging process to be directly transferred to the ground, thus providing anti-static protection. Static electricity can attract dust or product debris from the air, leading to material contamination. The anti-static design of this device avoids this problem, making it particularly suitable for packaging and conveying applications requiring high cleanliness, such as those in the food and pharmaceutical industries. Furthermore, in flammable and explosive environments, electrostatic discharge can cause fires or explosions; the anti-static design eliminates this risk.

[0065] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
