Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and in particular to a chili oil finished product packaging conveyor. Background Technology

[0002] On a chili oil production line, the finished product packaging conveyor usually consists of a horizontal main conveyor and several vertical split conveyors. It is used to collect and transport the glass bottles after filling and capping. The split conveyors are responsible for bringing the bottled products processed in the previous process into the main line, while the main conveyor is responsible for transporting the finished products to the next boxing or palletizing process.

[0003] In traditional transport and packaging processes, chili oil bottles on split conveyors are typically transported to the entrance of the main conveyor in single or multiple rows. To transfer the bottles from the split line to the main line, existing equipment often uses side-pushing mechanisms, pulleys, or simple guide plates. Once the bottles enter the main conveyor, they are usually transported by the friction of the conveyor belt or the limiting force of the side guardrails. Because glass bottles have smooth surfaces and regular shapes, to prevent them from tipping over during high-speed transport, the conveyor belt surface is often only equipped with simple anti-slip textures or shallow grooves, or manual sorting and arrangement of bottles at specific workstations is relied upon to ensure that the bottles maintain an orderly array when entering the unloading or packing area. However, traditional transport methods have the following drawbacks: First, existing conveyor systems lack rigid fixation for the bottle body, and glass bottles are prone to tipping over or breaking due to inertia or collision during transportation, causing production line shutdowns. Secondly, when bottles need to be transferred from the split line to the main line and arranged neatly, the existing bottle pushing or guiding methods cannot guarantee the absolute accuracy of the bottle position, resulting in uneven spacing between bottles and difficulty in forming a compact array. This causes inconvenience to the subsequent unloading process. In particular, when using vacuum suction cups for batch unloading, due to the uneven arrangement of the bottles or the excessive spacing, the suction cups cannot accurately pick up all the bottles at the same time, often requiring manual assistance in bottle arrangement.

[0004] Therefore, how to provide a finished chili oil packaging conveyor is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] One objective of this invention is to provide a finished chili oil packaging conveyor. This invention utilizes a magnetic attraction mechanism triggered by the sidewall contact of adjacent fixed equipment to simultaneously release pressure through a venting structure. This allows for the orderly arrangement and automatic release of glass bottles without manual intervention, eliminating the need for manual alignment and sorting of the bottles before unloading.

[0006] According to an embodiment of the present invention, a chili oil finished product packaging conveyor includes a transverse main conveyor and multiple longitudinal split conveyors. The main conveyor includes a conveyor body and a conveyor belt, and the surface of the conveyor belt is provided with multiple positioning grooves. The split conveyors include a conveyor body and a conveyor belt, and the conveyor belt is provided with fixing equipment. Fixing devices are used to secure glass bottles; The fixing device includes a base, a magnetic attraction structure, and a venting structure. The bottom of the base is equipped with a locking block that engages with the positioning groove. When the conveyor belt moves the fixing device to the connection point between the main conveyor and the split conveyor, the locking block is embedded in the positioning groove, so that multiple fixing devices are arranged sequentially on the conveyor belt of the main conveyor. When the side walls of adjacent fixing devices are in contact with each other, the magnetic attraction structure triggers the venting structure to release pressure and release the clamping constraint of the fixing device on the chili oil glass bottle.

[0007] Furthermore, the fixing device also includes two arc-shaped circular plates, the inner rings of which combine to form a circular space for accommodating the glass bottle. A fixing rod is fixedly connected to the base, one end of each of the two arc-shaped circular plates is hinged to the fixing rod, and a torsion spring is fixedly installed at the hinge between the two arc-shaped circular plates. An air pressure cushion is fixedly installed in the circular space formed by the inner rings of the two arc-shaped circular plates. The air pressure cushion is used to compress and fix the glass bottle when it is pushed into the circular space.

[0008] Furthermore, the magnetic attraction structure includes a magnetic block, and the circumference of the arc-shaped circular plate is configured as an arc surface and three planes. A limiting groove is opened on the plane facing the arc surface, and a moving rod is slidably arranged in the limiting groove. The magnetic block is fixedly arranged at one end of the moving rod, and a sealing head is provided at the other end of the moving rod.

[0009] Furthermore, the venting structure includes a venting valve port. The diameter of the opening at the end of the venting valve port closer to the inside of the air pressure pad is smaller than the diameter of the opening at the end farther from the inside. When two adjacent bases come into contact with each other, the adjacent magnetic blocks generate magnetic attraction, which drives the moving rod to move outward. When the sealing head disengages from the small-diameter port inside the venting valve port, the gas inside the air pressure pad leaks out through the venting valve port.

[0010] Furthermore, a tension spring is fitted on the moving rod. When the adjacent bases separate and the magnetic block is no longer under magnetic attraction, the tension spring provides elastic force to make the sealing head re-seal the vent valve port.

[0011] Furthermore, the air pressure cushion is also equipped with an inflation valve, which is used to inflate the air pressure cushion to restore the clamping and fixing state of the glass bottle after the fixed equipment completes the unloading cycle.

[0012] Furthermore, the conveyor belt surface of the split conveyor is provided with multiple slots, and multiple evenly distributed top blocks are provided in the slots. The bottom blocks of the base fit into the slots. When the conveyor belt is running, the base and the conveyor belt are driven to run synchronously through the cooperation of the slots and the pushing of the top blocks.

[0013] Furthermore, a rotating conveyor is installed outside the split conveyor. The rotating conveyor includes a rotary table, a rotating frame, and a drive source. Multiple placement slots are opened on the outer periphery of the rotating frame for placing glass bottles. The drive source is installed at the bottom of the rotary table and its output end is fixedly connected to the bottom axis of the rotating frame. The drive source drives the rotating frame to rotate intermittently. The rotation rhythm of the rotating frame matches the conveying rhythm of the split conveyor to ensure precise alignment between the placement slots and the clamping openings of the fixed equipment.

[0014] Furthermore, the rotary conveying device also includes a push source and grippers, which are installed inside the placement slot of the rotary frame. The push source drives the grippers to push the glass bottles between the arc-shaped circular plates of the fixed device.

[0015] The beneficial effects of this invention are: This invention utilizes a base-mounted locking block that adapts to the slots of the split conveyor and the positioning slots of the main conveyor. This allows the fixed equipment carrying glass bottles on multiple split conveyors to be orderly integrated into the main conveyor and automatically arranged at equal intervals. The pressure is simultaneously released by a magnetic attraction structure triggered by the sidewall contact of adjacent fixed equipment, which in turn triggers a pressure release structure. This eliminates the need for manual intervention to achieve the orderly arrangement and automatic release of the glass bottles from the clamps. It also eliminates the need for manual alignment and sorting of the bottles before unloading, reducing labor costs and increasing the automation level of the production line. At the same time, the pressure release operation is completed synchronously with the conveying action of the fixed equipment's convergence and contact, eliminating the need for separate sensors, solenoid valves, or other electrically and pneumatically controlled unlocking components. This simplifies the overall control circuit. Simultaneously, all glass bottles are released from their clamps at the same time, and the vacuum suction cup lifting device experiences no clamping resistance, effectively preventing bottle jamming, displacement, and bottle dropping.

[0016] This invention employs a flexible clamping structure combining a torsion spring-hinged arc-shaped circular plate with an air pressure cushion inside the fixing device. When the glass bottle is pushed in, the bottle body squeezes the arc-shaped circular plate to overcome the torsion spring's elasticity and open. After entering the inner ring, the air pressure cushion provides a uniformly wrapped clamping force, effectively avoiding the hard damage caused to the chili oil glass bottle by traditional rigid clamps. At the same time, the compressibility of gas adapts to the minute dimensional tolerances of different bottles, significantly reducing the bottle breakage rate during the transportation process.

[0017] The split conveyor belt is equipped with slots and top blocks. Through the cooperation of the slots and top blocks for limiting and synchronous pushing, the base and the conveyor belt are guaranteed to have no relative sliding, resulting in high conveying positioning accuracy. It can also smoothly push the fixed equipment laterally into the positioning slot of the main conveyor. The base transfer and switching is smooth and without jamming, ensuring the continuity of the split conveyor to the main conveyor. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0030] Example 1 like Figures 1 to 5 as well as Figures 7 to 9 As shown in the figure, the chili oil finished product packaging conveyor provided in this embodiment of the invention includes a transverse main conveyor 100 and a plurality of longitudinal split conveyors 200. The main conveyor 100 includes a conveyor body 101 and a conveyor belt 102. The surface of the conveyor belt 102 is provided with a plurality of positioning grooves 103. The split conveyors 200 include a conveyor body 201 and a conveyor belt 202. The conveyor belt 202 is provided with a fixing device 300. The fixing device 300 is used to fix the glass bottle 400; The fixing device 300 includes a base 310 and a magnetic attraction structure 320. When adjacent fixing devices 300 are attached together, they generate a magnetic attraction driving force, which serves as the power source for the venting structure 330. This eliminates the need for motors, cylinders, or solenoid valves to provide unlocking power, replacing external driving components with the physical magnetic attraction force of the contact, reducing electrical parts and simplifying the control program. Simultaneously, the magnetic attraction allows multiple bases 310 within the positioning groove 103 to attach to each other, better arranging the glass bottles 400 neatly. The venting structure 330, receiving the magnetic attraction driving force, releases pressure, directly releasing the clamping constraint on the glass bottles 400, releasing the bottles. The bottles are unlocked synchronously upon completion of the arrangement. With no clamping constraints, the vacuum suction cup grips the bottles without resistance, avoiding problems such as bottle jamming, bottle dropping, and gripping deviation. The bottom of the base 310 is provided with a connection to the positioning groove 103. The locking block 340, which is matched with the positioning groove 103, fits into each other and limits the fixed equipment 300 that enters the positioning groove 103 in the lateral and longitudinal directions. It forces all fixed equipment 300 to be arranged neatly at equal intervals. The mechanical structure forces the bottle body to be straightened without the need for manual intervention, eliminating the manual bottle sorting process, reducing labor costs, and ensuring consistent and stable arrangement. When the conveyor belt 202 moves the fixed equipment 300 to the connection between the main conveyor 100 and the split conveyor 200, the locking block 340 is embedded in the positioning groove 103, so that multiple fixed equipment 300 are arranged in sequence on the conveyor belt 102 of the main conveyor 100. When the side walls of adjacent fixed equipment 300 are in contact with each other, the magnetic attraction structure 320 triggers the venting structure 330 to release pressure and release the clamping constraint of the fixed equipment 300 on the chili oil glass bottle 400. In this implementation, during the packaging process of the finished chili oil, the filled and sealed glass bottles 400 are fixed to the fixing device 300 of the split conveyor 200. When the fixing device 300 moves with the conveyor belt 202 to the junction of the split conveyor 200 and the transverse main conveyor 100, the locking block 340 at the bottom of the base 310 of the fixing device 300 is precisely embedded into the positioning groove 103 of the main conveyor belt 102, thereby smoothly transferring the fixing device 300 to the main conveyor line. As the main conveyor belt 102 moves, multiple fixing devices 300 are arranged in sequence, and their side walls come into contact with each other. At the moment of contact, the magnetic attraction structure 320 on the fixing device 300 is triggered, which in turn triggers the venting structure 330 to release the pressure inside the fixing device 300, automatically releasing the clamping constraint on the chili oil glass bottles 400. At this time, the glass bottles 400 are in a neatly arranged and unrestrained state, which facilitates subsequent unloading, such as by vacuum suction cup lifting devices, for batch grabbing and unloading.

[0031] In contrast, traditional glass bottles 400 rely on photoelectric sensors, PLC program control, or manual intervention for transportation, sorting, and rapid unloading. Traditional chili oil workshops may have oil stains or dust, which can easily cause signal interference or malfunctions. In contrast, this invention uses a fixed device 300 to automatically arrange the bottles into the positioning slot 103, and automatically depressurizes them by adhering to the side walls. It can automatically arrange, sort, and depressurize and unload the bottles simultaneously by relying solely on the conveyor movement. It does not require external sensors, has strong anti-interference capabilities, and operates stably. Traditional clamps require complex opening and closing mechanisms during unloading, which can easily cause glass bottles 400 to break or become misaligned. In contrast, this invention utilizes the magnetic splicing between multiple bases 310 to achieve a self-adaptive switching between firmly clamping the glass bottles 400 during transport and automatically releasing them during unloading, making it compatible with vacuum suction cups for batch unloading. Traditional glass bottle 400 transportation methods require manual labor or complex bottle-sorting mechanisms to arrange the glass bottles 400 neatly after they converge on the main line. In contrast, this invention uses the positioning groove 103 and the locking block 340 to physically limit the bottles, automatically completing the equidistant array of bottles during transportation. At the same time, the magnetic attraction allows the multiple bases 310 in the positioning groove 103 to fit together, better arranging the glass bottles 400 neatly. They are automatically released before unloading, reducing labor costs and the bottle breakage rate.

[0032] The beneficial effects are achieved by adapting the bottom card block 340 of the base 310 to the slot 203 of the split conveyor 200 and the positioning slot 103 of the main conveyor 100, so that the fixed devices 300 carrying glass bottles 400 of the multi-group split conveyors 200 can be orderly merged into the main conveyor 100 and automatically arranged at equal intervals. The magnetic attraction structure 320 and the depressurization structure 330 are triggered by the side wall contact of the adjacent fixed devices 300 to release pressure synchronously. The orderly arrangement and automatic release of the glass bottles 400 can be completed without manual intervention. The manual alignment and sorting of the bottles before unloading is not required, which reduces labor costs and improves the automation level of the production line. At the same time, the depressurization operation is completed synchronously with the conveying action of the fixed devices 300 converging and contacting, without the need for separate configuration of sensors, solenoid valves and other electro- or pneumatic unlocking components, which simplifies the control circuit of the whole machine. At the same time, all glass bottles 400 are released from clamping restraints at the same time, and there is no clamping resistance when the vacuum suction cup lifter grabs them, which effectively avoids bottle jamming, displacement and bottle falling problems.

[0033] See also Figures 7 to 8As shown, in order to autonomously clamp and fix the glass bottle 400, the fixing device 300 also includes two arc-shaped circular plates 350. The inner rings of the two arc-shaped circular plates 350 are combined to form a circular space for accommodating the glass bottle 400. A fixing rod 360 is fixedly connected to the base 310, vertically fixed to the upper end of the base 310, serving as a common hinge fulcrum for the two sets of arc-shaped circular plates 350. This limits the opening and closing rotation trajectory of the arc-shaped circular plates 350, ensuring that the two sets of arc-shaped circular plates 350 open and close coaxially and with consistent opening and closing angles. The integrated fixed-point hinge ensures no offset during opening and closing, guaranteeing that the center of the inner circular space is always aligned with the center of the glass bottle 400, resulting in uniform clamping force and preventing the bottle from tilting due to clamping on one side. One end of each of the two arc-shaped circular plates 350 is hinged to the fixing rod 360, and a torsion bar is fixedly installed at the hinge between the two arc-shaped circular plates 350. Spring 370, with its arc-shaped design, provides a natural guiding and flaring effect when the glass bottle 400 is pushed in, allowing it to slide in smoothly without extremely high alignment precision. The torsion spring 370 provides a continuous and gentle centripetal force, avoiding the instantaneous mechanical impact caused by rigid clamping and reducing the risk of the glass bottle 400 breaking during loading. An air pressure pad 380 is fixedly installed in the circular space formed by the inner rings of the two arc-shaped circular plates 350. The air pressure pad 380 is used to compress and fix the glass bottle 400 when it is pushed into the circular space. The air pressure pad 380 has compressibility and deformation capability, which can adapt to the small dimensional tolerances that may occur in the production of chili oil glass bottles 400. At the same time, the flexible contact surface effectively protects the surface of the glass bottle 400, preventing hard scratches, and the force is evenly distributed, greatly improving the stability of clamping. In the implementation method, when not in operation: the two sets of arc-shaped circular plates 350 rely on the original elastic force of the torsion springs 370 at the hinge to keep the openings at the movable ends slightly open. The inner rings of the arc-shaped circular plates 350 enclose a circular receiving space that fits the outer diameter of the red oil glass bottle 400. The air pressure cushion 380 is in a preset inflated and pressurized state, and the venting structure 330 is in a sealed and pressure-maintaining state. At this time, the fixed device 300 is placed alone on the split conveyor 200. The devices are not attached to each other, the magnetic attraction structure is not triggered, and the air pressure cushion 380 maintains pressure and has clamping ability. During the clamping and securing of the glass bottle 400: The filled and sealed glass bottle 400 is pushed laterally into the circular space from the opening side of the arc-shaped circular plate 350. The outer wall of the bottle compresses the two sets of arc-shaped circular plates 350, overcoming the torque of the torsion spring 370, causing the two sets of arc-shaped circular plates 350 to rotate outward around the fixing rod 360 and widen. The bottle body is completely seated inside the circular space. At the same time, the bottle wall compresses the inner ring air pressure pad 380 inward. The air pressure pad 380 is further compressed and stores pressure. Relying on the rotational clamping force of the torsion spring 370 and the compressive rebound squeezing force of the air pressure pad 380, the outer wall of the glass bottle 400 is held tightly in both directions, completing the autonomous clamping and securing. When the fixed equipment 300 is transported to the main conveyor: the fixed equipment 300 is transferred to the junction of the split conveyor 200 and the main conveyor 100. The base 310 and the locking block 340 are embedded in the positioning groove 103 of the main conveyor 100. Multiple sets of fixed equipment 300 are arranged at equal intervals and the side walls are attached to each other. The magnetic attraction structure 320 triggers the venting structure 330 to release pressure. The air pressure cushion 380 releases pressure and rebounds, releasing the pressure and restraint on the outer wall of the glass bottle 400. The torsion spring 370 is no longer clamped. The glass bottle 400 is not clamped or limited and is placed in the fixed equipment 300 to wait for the vacuum suction cup to unload. In terms of structure, the fixing device 300 is an adaptive flexible clamping structure in the overall scheme, which solves the positioning and anti-tipping problems of the chili oil glass bottle 400 during high-speed conveying. At the same time, the fixing device 300 is responsible for firmly locking the glass bottle 400 within the fixing device 300 during the operation of the split conveyor 200 and the main conveyor 100. When the base 310 contacts and releases pressure, the air pressure cushion 380 loses its clamping force, and the glass bottle 400 is unrestrained and rests in the positioning slot 103 of the main conveyor 100, waiting for the vacuum suction cup to unload.

[0034] The beneficial effects are achieved by using a flexible clamping structure inside the fixed device 300, which combines an arc-shaped circular plate 350 hinged by a torsion spring 370 with an air pressure cushion 380. When the glass bottle 400 is pushed in, the bottle body squeezes the arc-shaped circular plate 350 to overcome the elastic force of the torsion spring 370 and open it. After entering the inner ring, the air pressure cushion 380 provides a uniform clamping force, which effectively avoids the hard damage to the chili oil glass bottle 400 caused by traditional rigid clamps. At the same time, the compressibility of gas adapts to the small dimensional tolerances of different bottles, which greatly reduces the bottle breakage rate during the transportation process.

[0035] See also Figures 7 to 11As shown, in order to release the fixing device 300 from the fixing state of the glass bottles 400 when arranging them, the magnetic attraction structure 320 includes a magnetic block 321. The circumference of the arc-shaped circular plate 350 is set as an arc surface and three planes. A limiting groove 322 is opened on the plane facing the arc surface. A moving rod 323 is slidably arranged in the limiting groove 322. The magnetic block 321 is fixedly arranged at one end of the moving rod 323. A sealing head 324 is provided at the other end of the moving rod 323. The venting structure 330 includes a venting valve port 331. The opening diameter of the venting valve port 331 near the inside of the air pressure pad 380 is smaller than the opening diameter of the end away from the inside. When two adjacent bases 310 When they come into contact, the adjacent magnetic blocks 321 generate a magnetic attraction force, which drives the moving rod 323 to move outward. When the sealing head 324 disengages from the small-diameter port inside the vent valve 331, the gas in the air pressure pad 380 leaks out through the vent valve 331. A tension spring 332 is sleeved on the moving rod 323. When the adjacent bases 310 separate and the magnetic blocks 321 are no longer subject to magnetic attraction, the tension spring 332 provides elastic force to make the sealing head 324 re-seal the vent valve 331. An inflation valve 390 is also provided on the air pressure pad 380. The inflation valve 390 is used to inflate the air pressure pad 380 after the fixed equipment 300 completes the unloading cycle to restore the clamping and fixing state of the glass bottle 400. In this embodiment, the outer circumferential surface of the arc-shaped circular plate 350 on the base 310 is machined into an arc surface and three planes. A limiting groove 322 is formed on the plane facing the arc surface, and a movable rod 323 is slidably installed within the groove. One end of the movable rod 323 is fixed with a magnetic block 321, and the other end is machined into a sealing head 324. A venting valve 331 is provided on the air pressure cushion 380. This valve is designed in a stepped shape, with the opening diameter at the end closer to the inside being smaller than that at the end farther from the inside. When two adjacent bases 310 are in contact with each other on the main transport line, the magnetic blocks 321 on both sides... 1. A magnetic attraction force is generated, which pulls the moving rod 323 to slide outward, causing the sealing head 324 to disengage from the small-diameter port inside the vent valve 331. The gas in the air pressure pad 380 then quickly leaks out. When the base 310 separates and the magnetic attraction force disappears, the tension spring 332 sleeved on the moving rod 323 provides a return force, forcing the sealing head 324 to re-seal the valve port. In addition, the air pressure pad 380 is also equipped with an inflation valve 390. When the empty base 310 returns to the starting end, the air pressure pad 380 can be re-inflated by an external inflation device to restore its clamping capacity.

[0036] The structure, with its magnetic attraction structure 320 and venting structure 330, transforms the physical splicing action of the base 310 on the conveyor line into a depressurization action inside the air pressure pad 380. During the conveying stage, it ensures that the air pressure pad 380 is in an inflated and sealed state, clamping and fixing the glass bottle 400. During the unloading stage, the adjacent magnetic blocks 321 generate magnetic attraction, causing the gas inside the air pressure pad 380 to leak out through the venting valve 331, freeing the glass bottle 400 from clamping constraints and facilitating batch unloading by the vacuum suction cup.

[0037] The beneficial effects are that existing conventional pneumatic clamping conveyors all require PLC, photoelectric switches, and solenoid valves to control the inflation and deflation of each set of clamps, which is complicated in programming and debugging and has high electrical control costs. This structure uses the magnetic attraction of the base 310 to depressurize and the spring sealing of the base 310 to seal the air. The entire process does not rely on any electrical control components. It autonomously completes the clamping and opening of the glass bottle 400 by mechanical action, eliminating the need for a complete pneumatic and electrical control system. Traditional pin-type depressurization structures (330) are prone to problems such as partial opening and closing, incomplete depressurization, and continued bottle clamping. This structure, however, uses magnetic attraction to fully open the valve and spring push to fully close it, offering only two states: fully open and fully closed. There is no intermediate partial depressurization state, which structurally avoids problems such as bottle jamming or bottle displacement during unloading.

[0038] See also Figures 4 to 5 As shown, in order to ensure that there is no relative sliding between the base 310 and the conveyor belt 202, the surface of the conveyor belt 202 of the split conveyor 200 is provided with multiple slots 203, and multiple evenly distributed top blocks 204 are provided in the slots 203. The bottom block 340 of the base 310 matches the slot 203. When the conveyor belt 202 is running, the base 310 and the conveyor belt 202 are driven to run synchronously through the cooperation of the block 340 and the slot 203 and the pushing of the top block 204.

[0039] In this embodiment, multiple slots 203 are equidistantly provided on the surface of the conveyor belt 202 of the split conveyor 200 along the running direction, and multiple evenly distributed top blocks 204 are fixedly installed in the slots 203. The bottom of the base 310 of the fixing device 300 is formed with a block 340 that matches the shape of the slot 203. When the base 310 is pushed onto the conveyor belt 202 of the split conveyor 200, the block 340 at the bottom of the base 310 is embedded into the corresponding slot 203, forming a geometric limit. When the conveyor belt 202 is running, the cooperation between the side wall of the slot 203 and the block 340 provides a basic synchronous traction force. At the same time, the top block 204 in the slot 203 will actively abut against the force-bearing surface of the block 340, and drive the base 310 and the conveyor belt 202 to run synchronously through mechanical thrust until the base 310 is successfully sent into the positioning slot 103 of the main conveyor 100.

[0040] Structural function: Since the base 310 of the fixed equipment 300 supports the glass bottle of chili oil 400, it has a large inertia and mass. If it relies solely on the friction force of the surface of the conveyor belt 202, it is easy for relative sliding to occur during high-speed start-up, stop or handover. The active pushing of the top block 204 ensures that the base 310 can still maintain synchronous operation with the conveyor belt 202 even under heavy load or when there is chili oil stains on the surface of the conveyor belt 202.

[0041] The beneficial effects are that the conveyor belt 202 of the split conveyor 200 is equipped with a slot 203 and a top block 204. Through the cooperation of the slot 203 limiting the position of the slot 340 and the top block 204 pushing synchronously, it is ensured that there is no relative sliding between the base 310 and the conveyor belt 202, the conveying positioning accuracy is high, and the fixed equipment 300 can be smoothly pushed laterally into the positioning slot 103 of the main conveyor 100. The base 310 transfers and switches smoothly without jamming, ensuring the continuity of the split conveyor 200 to the main conveyor 100.

[0042] Example 2 like Figure 6 As shown, a rotating conveyor 500 is provided outside the split conveyor 200. The rotating conveyor 500 includes a rotating table 501, a rotating frame 502, and a drive source 503. The rotating frame 502 has multiple placement slots 504 on its outer periphery for placing glass bottles 400. The drive source 503 is installed at the bottom of the rotating table 501 and its output end is fixedly connected to the bottom axis of the rotating frame 502. The drive source 503 drives the rotating frame 502 to rotate intermittently. The rotation rhythm of the rotating frame 502 matches the conveying rhythm of the split conveyor 200 to ensure that the placement slots 504 are accurately aligned with the clamping openings of the fixed device 300. The rotating conveyor 500 also includes a push source 505 and a gripper 506. The push source 505 and the gripper 506 are installed inside the placement slots 504 of the rotating frame 502. The push source 505 drives the gripper 506 to push the glass bottles 400 between the arc-shaped circular plates 350 of the fixed device 300. In this embodiment, a rotating conveying device 500 is installed on the outside of the split conveyor 200. The device mainly consists of a rotating table 501, a rotating frame 502, and a drive source 503. The drive source 503 is installed at the bottom of the rotating table 501, and its output shaft is fixedly connected to the bottom axis of the rotating frame 502, thereby driving the rotating frame 502 to rotate intermittently. Multiple placement slots 504 are evenly opened on the outer periphery of the rotating frame 502 for temporarily storing the glass bottles 400 to be transferred. Inside each placement slot 504 of the rotating frame 502, a push source 505 and a gripper 506 mechanism are also integrated. In actual operation, the rotation rhythm of the rotating frame 502 is precisely matched with the conveying rhythm of the split conveyor 200, ensuring that when the rotating frame 502 stops, the opening of the placement slot 504 is precisely aligned with the clamping opening of the arc-shaped circular plate 350 of the fixed device 300 on the split conveyor line. At this time, the push source 505 drives the gripper 506 to move, smoothly pushing the glass bottle 400 in the placement slot 504 between the arc-shaped circular plates 350 of the fixed device 300, completing the feeding action. This application does not limit the specific structure of the drive source 503 and the actuation source 505, which are preferably a servo motor and a cylinder, respectively. The specific structure and working principle of the servo motor and the cylinder are existing technologies and will not be described in detail here.

[0043] Through the combination of intermittent indexing and active pushing, the structure ensures that the glass bottle 400 can be safely and undamagedly delivered into the fixed device 300 with extremely precise timing and spatial positioning.

[0044] The beneficial effect is that the intermittent indexing of the rotating frame 502 is achieved by the drive source 503, so that the feeding action is matched with the operation of the split conveyor 200. This rhythm matching of movement and stop eliminates the positional error caused by continuous rotation or continuous conveyor belt 202, ensures the alignment of the placement trough 504 with the opening of the fixed equipment 300, and avoids mechanical interference or misalignment during feeding.

[0045] Working principle: During the feeding and clamping stage, the rotating conveyor 500 drives the rotating frame 502 to rotate intermittently through the drive source 503. Its rhythm is precisely matched with the running rhythm of the split conveyor 200. When the placement trough 504 is aligned with the opening of the fixed device 300 on the split conveyor 200, the drive source 505 drives the gripper 506 to actively push the glass bottle 400 into the fixed device 300. At this time, the glass bottle 400 squeezes the arc-shaped plate 350 to overcome the resistance of the torsion spring 370 and opens. At the same time, the bottle body squeezes the inner ring air pressure pad 380 of the arc-shaped plate 350 to complete the compression and pressure storage. Relying on the rebound mechanical force of the torsion spring 370 and the pressure elastic force of the air pressure pad 380, the glass bottle 400 is clamped in both directions to complete the autonomous clamping and fixing. Top blocks 204 are evenly distributed in the slot 203. The bottom block 340 of the base 310 fits into the slot 203. When the conveyor belt 202 is running, the top blocks 204 push the block 340 laterally, causing the base 310 and the fixing device 300 that clamps the glass bottle 400 above to move synchronously and equidistantly with the conveyor belt 202. When the fixing device 300 moves to the connection position between the split conveyor 200 and the main conveyor 100, the top blocks 204 continue to push the base 310, causing the block 340 of the base 310 to disengage from the slot 203 and embed into the positioning groove 103 on the surface of the conveyor belt 102 of the main conveyor 100. Multiple split conveyors 200 feed materials in sequence, so that multiple sets of fixing devices 300 are arranged equidistantly on the main conveyor 100, and the outer planes of adjacent fixing devices 300 fit together. A limiting groove 322 is opened on the outer plane of the arc-shaped circular plate 350. A moving rod 323 with a magnetic block 321 and a sealing head 324 is slidably assembled in the groove. The moving rod 323 is sleeved with a tension spring 332. After the adjacent fixed equipment 300 is attached, the magnetic blocks 321 on both sides magnetically attract each other. The magnetic attraction force overcomes the elastic force of the tension spring 332 and pulls the moving rod 323 outward, so that the sealing head 324 is separated from the small diameter port inside the variable diameter vent valve 331 of the air pressure pad 380. The gas inside the air pressure pad 380 is released and depressurized, releasing the flexible clamping restraint on the outer wall of the glass bottle 400. The glass bottle 400 is released from the clamping limit and is placed in the positioning groove 103 of the main conveyor 100. Through the magnetic attraction between the positioning groove 103 and the adjacent base 310, the glass bottles 400 in a single positioning groove 103 are neatly arranged without the need for manual arrangement, so that the subsequent vacuum suction cup lifting device can directly and unblock the batch unloading. After the glass bottle 400 is unloaded, the empty fixed equipment 300 is conveyed back and separated from each other. The magnetic attraction of the magnetic block 321 disappears, the tension spring 332 pulls the moving rod 323 to reset, the sealing head 324 re-seals the vent valve port 331, and the air pressure pad 380 returns to the sealed and pressure-maintaining state. After the empty fixed equipment 300 is transferred to the feeding station, it is replenished with air and stored through the external air inflation valve 390 of the air pressure pad 380, resets the clamping state, and can then receive glass bottles 400 again, realizing the closed-loop recycling of the fixed equipment 300.
