Description

Technical Field

[0001] This application relates to the field of packaging equipment technology, and in particular to an automatic packaging machine for finished guardrail products. Background Technology

[0002] After production, highway guardrail posts need to be packaged and transported. Multiple sets of guardrail posts need to be stacked and packaged to reduce the risk of scratches and damage to the anti-corrosion layer during transportation. Traditionally, packaging is done manually, wrapping the stacked guardrail posts with plastic sheeting. However, with increasing market demand, manual packaging can no longer meet the growing production needs. Therefore, an automatic packaging machine for finished guardrail products is required.

[0003] A related automatic packaging machine for finished guardrails includes a conveying component, a packaging component, and a clamping component. The conveying component conveys the stacked guardrail posts through the packaging component. The packaging component and the clamping component work together to wrap plastic sheeting around the guardrail posts.

[0004] However, existing automatic packaging machines for finished guardrails lack a fixing measure at the end of the wrapped plastic sheet, which makes the wrapped plastic sheet easy to unravel. This requires manual reinforcement by workers, reducing the working efficiency of the automatic packaging machine for finished guardrails. Utility Model Content

[0005] To address the issue of insufficient securing measures at the ends of the wrapped plastic sheet in automatic packaging machines for finished guardrails, this application provides an automatic packaging machine for finished guardrails.

[0006] This application provides an automatic packaging machine for finished guardrail products, which adopts the following technical solution: An automatic packaging machine for finished guardrail products includes: The packaging component is fixed on the ground and can automatically wrap plastic sheeting around the finished guardrail as it passes by. The conveying component is fixedly installed on the ground, and two sets of conveying components are installed at both ends of the packaging component. The clamping component is fixedly mounted on the packaging component. The clamping component can hold the wrapped plastic sheet and assist the packaging component in wrapping the plastic sheet for the next set of guardrail products. The glue application component is fixedly installed on the packaging component and can apply glue to the ends of the wound plastic sheet.

[0007] By adopting the above technical solution, the packaging component provides installation space for the clamping component and the gluing component. The two sets of conveying components work in sequence to convey the finished guardrails through the packaging component. The packaging component wraps the finished guardrails with plastic sheeting. The clamping component cuts and fixes the wrapped plastic sheeting to the plastic sheeting connected to the packaging component, making it easier for the packaging component to pack the next set of finished guardrails. The gluing component applies glue to the plastic sheeting connected to the finished guardrails to fix it, so that the wrapped plastic sheeting will not come undone. This reduces the need for workers to manually reinforce the plastic sheeting afterward and speeds up the working efficiency of the automatic packaging machine for finished guardrails.

[0008] Optional, packaging components include: A fixed base is fixedly installed on the ground, and a horizontal conveying hole is provided on the fixed base. The mounting bracket is vertically fixed on the base, and the mounting bracket is set in accordance with the transfer hole. A rotating ring is fitted onto a mounting bracket, and an arc-shaped rack is fixedly provided on the circumference of the rotating ring; The packaging motor is horizontally and fixedly mounted on the periphery of the fixed base, and the output end of the packaging motor passes through the fixed base. The gear is fixedly mounted on the output end of the packaging motor and meshes with the arc-shaped rack. The mounting shaft is horizontally fixed on the circumference of the rotating ring, and the mounting shaft is parallel to the central axis of the rotating ring. A rotating roller is mounted on a mounting shaft, and a roll of plastic sheeting is mounted on the rotating roller. The guide rod is horizontally fixed on the side of the rotating ring and is parallel to the mounting shaft.

[0009] By adopting the above technical solution, the fixed base provides installation space for other mechanisms of the packaging component. The rotating ring can rotate around the central axis of the mounting frame. The rotation of the packaging motor can drive the gear to rotate synchronously. Because the gear and the arc rack mesh, the rotation of the gear can drive the rotating ring to rotate. The rotation of the rotating ring can drive the mounting shaft and the rotating roller to rotate synchronously around the mounting central axis. The guide rod can guide the plastic sheet on the rotating roller, reducing the probability of the plastic sheet wrinkling and tangling. This allows the plastic sheet on the rotating roller to be smoothly wound onto the finished guardrail product passing through the conveying hole, thereby completing the purpose of packaging the finished guardrail product. By adopting mechanized winding of the plastic sheet, the winding speed of the plastic sheet is accelerated, and the work efficiency of packaging the finished guardrail product is improved.

[0010] Optionally, the transmission components include: A transmission base is fixedly set on the ground, with one end of the transmission base corresponding to the fixed base. Conveyor rollers are rotatably mounted on a conveyor base, and multiple sets of conveyor rollers are spaced apart along the length of the conveyor base. The conveyor motor is fixedly mounted on the conveyor base. The output end of the conveyor motor passes through the conveyor base and is fixedly connected to one end of the conveyor roller. Multiple sets of conveyor motors and conveyor rollers are provided correspondingly.

[0011] By adopting the above technical solution, the conveyor base provides installation space for the conveyor rollers and the conveyor motor. The rotation of the conveyor motor can drive the conveyor rollers to rotate synchronously. The synchronous rotation of multiple sets of conveyor rollers can drive the finished guardrail products placed on the conveyor rollers to move along the length of the conveyor base, thereby achieving the purpose of conveying the finished guardrail products through the packaging components.

[0012] Optionally, the clamping components include: The clamping frame is fixedly mounted on the fixed base; The first telescopic rod is horizontally fixed on the clamping frame. The telescopic direction of the first telescopic rod is parallel to the mounting shaft. A first telescopic plate is horizontally fixed on the telescopic end of the first telescopic rod. The second telescopic rod is horizontally fixed on the clamping frame. The telescopic direction of the second telescopic rod is parallel to the mounting shaft. A second telescopic plate is horizontally fixed on the telescopic end of the second telescopic rod. The second telescopic plate is parallel to the first telescopic plate. The motor is fixed horizontally around the clamping frame. A rotating shaft is rotatably mounted on the periphery of the clamping frame, with one end of the rotating shaft fixedly connected to the output end of a fixed motor. A fixing plate is fixedly installed on the rotating shaft, and two sets of fixing plates are spaced apart along the length of the rotating shaft. The cutting blade is fixedly mounted on the end of the first telescopic plate away from the first telescopic rod.

[0013] By adopting the above technical solution, the clamping frame provides installation space for other mechanisms of the clamping assembly. The extension of the first telescopic rod can drive the first telescopic plate to move closer to the rotating ring, and the extension of the second telescopic rod can drive the second telescopic plate to move closer to the rotating ring. The rotation of the fixed motor can drive the rotating shaft to rotate synchronously, and the rotation of the rotating shaft can drive the fixed plate to rotate synchronously. When the first and second telescopic plates extend to the bottom of the plastic sheet being wrapped, the rotating ring rotates an additional turn so that the plastic sheet wraps around the lower surfaces of the first and second telescopic plates. The rotation of the fixed motor drives the fixed plate to rotate and clamps the plastic sheet tightly to the first telescopic plate. On the lower surface of the first and second telescopic plates, the first telescopic rod shortens, causing the first telescopic plate to reset. The first telescopic plate then moves the cutting blade towards the clamping frame. During this movement, the cutting blade cuts the plastic sheet, so that the plastic sheet connected to the finished guardrail is no longer fixed by the clamping components. Instead, the plastic sheet connected to the rotating roller is clamped and fixed by the second telescopic plate and the fixing plate. This makes it easier for workers to operate the packaging components to package the next set of finished guardrails. It reduces the step of manually fixing one end of the plastic sheet to the finished guardrail before wrapping it, thus reducing the workload of workers and improving the packaging efficiency of the automatic packaging machine for finished guardrails.

[0014] Optionally, the adhesive application assembly includes: Industrial glue applicator, the industrial glue applicator is fixedly mounted on a fixed base; A dispensing valve is horizontally fixed on the first telescopic plate, with the dispensing port of the dispensing valve pointing towards the side of the first telescopic plate away from the second telescopic plate. The hose connects the industrial glue dispenser and the dispensing valve. The third telescopic rod is horizontally fixed on the fixed base, and the telescopic direction of the third telescopic rod is perpendicular to the telescopic direction of the first telescopic rod. The push plate is horizontally fixed at the telescopic end of the third telescopic rod, and the length of the push plate is the same as the length of the rotating roller.

[0015] By adopting the above technical solution, the industrial glue machine can inject industrial glue into the dispensing valve through a hose. The dispensing valve controls the glue dispensing amount. When the first telescopic rod shortens, it drives the first telescopic plate to move closer to the clamping block. The movement of the first telescopic plate drives the dispensing valve to move synchronously. The dispensing valve dispenses glue onto the edge of the plastic sheet connected to the finished guardrail. After the first telescopic plate drives the dispensing valve away from the plastic sheet, the third telescopic rod extends and drives the push plate to move closer to the plastic sheet. The push plate pushes the glued plastic sheet to fit tightly with the plastic sheet wrapped around the finished guardrail, thus bonding the plastic sheet wrapped around the finished guardrail together with industrial glue. This makes the wrapped plastic sheet less likely to come undone, reducing the need for manual reinforcement of the plastic sheet and increasing the working efficiency of the automatic packaging machine for finished guardrails.

[0016] Optionally, friction pads are fitted onto the conveyor rollers.

[0017] By adopting the above technical solution, the friction pad can increase the friction between the conveyor roller and the finished guardrail, and enhance the transmission effect of the conveyor roller on the finished guardrail.

[0018] Optionally, a bidirectional hydraulic rod is horizontally fixed on the conveyor base. Each of the two sets of telescopic ends of the bidirectional hydraulic rod is inclinedly fixed with a positioning shaft. A positioning roller is sleeved on the positioning shaft, and the positioning shaft and the positioning roller are rotatably connected.

[0019] By adopting the above technical solution, the shortening of the bidirectional hydraulic rod can drive the two sets of positioning axes to move towards the finished guardrail, so that the positioning rollers come into contact with the finished guardrail. The positioning rollers can clamp and position the finished guardrail. At the same time, the setting of the positioning rollers changes the sliding friction between the positioning shaft and the finished guardrail to rolling friction, reducing the impact of frictional resistance on the transmission of the finished guardrail and improving the smoothness and efficiency of the transmission of the finished guardrail.

[0020] Optionally, multiple sets of bidirectional hydraulic rods, positioning shafts, and positioning rollers are arranged at intervals along the length of the conveyor base.

[0021] By adopting the above technical solution, the setting of multiple sets of bidirectional hydraulic rods, positioning shafts and positioning rollers can realize the full positioning of stacked guardrail products, improve the transmission stability of guardrail products, reduce the probability of plastic sheeting loosening during winding, and improve the packaging tightness of packaging components.

[0022] In summary, this utility model embodiment provides an automatic packaging machine for finished guardrail products, which includes at least one of the following beneficial technical effects: 1. The packaging component provides installation space for the clamping component and the gluing component. The two sets of conveying components work in sequence to convey the finished guardrails through the packaging component. The packaging component wraps the finished guardrails with plastic sheeting. The clamping component cuts and fixes the wrapped plastic sheeting to the plastic sheeting connected to the packaging component, making it easier for the packaging component to pack the next set of finished guardrails. The gluing component applies glue to the plastic sheeting connected to the finished guardrails to fix it, so that the wrapped plastic sheeting will not come undone. This reduces the need for workers to manually reinforce the plastic sheeting afterward and speeds up the working efficiency of the automatic packaging machine for finished guardrails.

[0023] 2. The shortening of the bidirectional hydraulic rod can drive the two sets of positioning axes to move closer to the finished guardrail, so that the positioning rollers come into contact with the finished guardrail. The positioning rollers can clamp and position the finished guardrail. At the same time, the setting of the positioning rollers changes the sliding friction between the positioning shaft and the finished guardrail to rolling friction, reducing the impact of frictional resistance on the transmission of the finished guardrail, and improving the smoothness and efficiency of the transmission of the finished guardrail.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] Combination Figure 1This application discloses an automatic packaging machine for finished guardrail products, including: a packaging component 1, a conveying component 2, a clamping component 3, and an adhesive application component 4; the packaging component 1 is fixedly installed on the ground and can automatically wrap plastic sheeting around the passing finished guardrail products 61; the conveying component 2 is fixedly installed on the ground and has two sets of corresponding components at both ends of the conveying component 2 and the packaging component 1; the clamping component 3 is fixedly installed on the packaging component 1 and can fix the wrapped plastic sheeting and assist the packaging component 1 in wrapping the next set of finished guardrail products 61 with plastic sheeting; the adhesive application component 4 is fixedly installed on the packaging component 1 and can apply adhesive to the end of the wrapped plastic sheeting.

[0028] In this embodiment, the packaging component 1 provides installation space for the clamping component 3 and the gluing component 4. Two sets of conveying components 2 are respectively arranged at both ends of the width direction of the packaging component 1. The two sets of conveying components 2 can sequentially convey the finished guardrail 61 through the packaging component 1. When the packaging component 1 is activated, it can wrap plastic sheeting around the finished guardrail 61. After the finished guardrail 61 is wrapped with plastic sheeting, the clamping component 3 can cut the plastic sheeting and fix the end of the plastic sheeting connected to the packaging component 1, assisting the packaging component 1 in packaging the next set of finished guardrail 61. The gluing component 4 can apply glue to the end of the plastic sheeting connected to the finished guardrail 61, making the plastic sheeting stick together, improving the firmness of the wrapped plastic sheeting, reducing the probability of the plastic sheeting coming undone. At the same time, the amount of glue applied by the gluing component 4 is adjustable, improving the adhesion effect of the plastic sheeting, and improving the working quality and efficiency of the automatic packaging machine for finished guardrails.

[0029] In practical use, the staff places the stacked guardrail finished products 61 on the conveyor component 2. The staff starts the conveyor component 2, and the guardrail finished products 61 are conveyed through the packaging component 1. When one end of the guardrail finished product 61 passes through the packaging component 1, the staff starts the packaging component 1 to wrap the guardrail finished product 61 with plastic sheeting. After the guardrail finished product 61 is wrapped, the clamping component 3 cuts the plastic sheeting and fixes it to the plastic sheeting connected to the packaging component 1. The glue application component 4 evenly applies glue to the end of the plastic sheeting connected to the guardrail finished product 61 to make the plastic sheeting stick together. When the packaging component 1 packages the next group of guardrail finished products 61, one end of the plastic sheeting is fixed by the clamping component 3, and the other end is wrapped to the guardrail finished product 61 through the packaging component 1. After the packaging component 1 wraps the plastic sheeting around the next group of guardrail finished products 61 once, the clamping component 3 releases the plastic sheeting to reduce the impact on the wrapping component. After the plastic sheeting is wrapped, the above steps are repeated to achieve automatic continuous packaging of guardrail finished products 61.

[0030] Combination Figure 1 , Figure 2 and Figure 3In one specific embodiment, the packaging component 1 includes: a fixed base 11, a mounting frame 12, a rotating ring 13, a packaging motor 14, a gear 15, a mounting shaft 16, a rotating roller 17, and a guide rod 18. The fixed base 11 is fixedly mounted on the ground, and a conveying hole 60 is horizontally provided on the fixed base 11. The mounting frame 12 is vertically fixedly mounted on the fixed base 11, and the mounting frame 12 is correspondingly arranged with the conveying hole 60. The rotating ring 13 is sleeved on the mounting frame 12, and an arc-shaped rack 51 is fixedly provided on the periphery of the rotating ring 13. The packaging motor 14... 4. A horizontally fixed installation is provided around the fixed base 11. The output end of the packaging motor 14 passes through the fixed base 11. A gear 15 is fixedly installed on the output end of the packaging motor 14. The gear 15 meshes with the arc-shaped rack 51. A mounting shaft 16 is horizontally fixedly installed around the rotating ring 13. The mounting shaft 16 is parallel to the central axis of the rotating ring 13. A rotating roller 17 is sleeved on the mounting shaft 16. A roll of plastic cloth is installed on the rotating roller 17. A guide rod 18 is horizontally fixedly installed around the rotating ring 13. The guide rod 18 is parallel to the mounting shaft 16.

[0031] In this embodiment, the fixed base 11 is L-shaped, the conveying hole 60 is cylindrical, the mounting frame 12 is annular with the same inner diameter as the conveying hole 60, and the rotating ring 13 is annular with the same inner diameter as the mounting frame 12. The mounting frame 12 and the rotating ring 13 are fitted with a clearance, allowing the rotating ring 13 to rotate smoothly around the outer periphery of the mounting frame 12. The rotation of the output end of the packaging motor 14 is not affected by the fixed base 11. The rotation of the output end of the packaging motor 14 can drive the gear 15 to rotate synchronously. The rotation of the gear 15 can drive the arc-shaped rack 51 and the rotating ring 13 to rotate around the outer periphery of the mounting frame 12. The tooth ratio of the gear 15 and the arc-shaped rack 51 is specifically designed according to actual conditions and is not specifically limited in this embodiment. The mounting shaft 16 is cylindrical, and the rotating roller 17 is cylindrical. The rotating roller 17 can rotate smoothly around the mounting shaft 16. A roll of plastic sheeting can be mounted on the rotating roller 17. When the plastic sheeting is under tension, the rotating roller 17 can rotate around the mounting shaft 16, causing the plastic sheeting on the rotating roller 17 to gradually detach. The guide rod 18 is cylindrical and can guide the detached plastic sheeting on the rotating roller 17, reducing the probability of wrinkles when the detached plastic sheeting is rewound. The rotation of the rotating ring 13 can drive the mounting shaft 16 and the rotating roller 17 to rotate around the central axis of the mounting frame 12. When the finished guardrail 61 passes through the rotating roller 17, one end of the plastic sheeting mounted on the rotating roller 17 is fixed to the finished guardrail 61. The plastic sheeting on the rotating roller 17 detaches and, driven by the rotating ring 13, wraps around the surface of the finished guardrail 61, forming a tight wrapping layer, reducing the risk of wear and tear on the finished guardrail 61 during transportation.

[0032] In practical use, the staff transports the finished guardrail 61 through the conveyor hole 60 via the conveyor component 2. When one end of the finished guardrail 61 approaches the conveyor hole 60, the staff starts the packaging motor 14. The packaging motor 14 rotates, driving the gear 15 to rotate synchronously. The rotation of the gear 15 drives the arc-shaped rack 51 and the rotating ring 13 to rotate. The rotating ring 13 drives the mounting shaft 16 and the rotating roller 17 to rotate around the central axis of the mounting frame 12. One end of the plastic sheet is fixed to the surface of the finished guardrail 61. As the rotating roller 17 rotates, the plastic sheet on the rotating roller 17 detaches and wraps around the surface of the finished guardrail 61. As the finished guardrail 61 gradually passes through the conveyor hole 60, the plastic sheet tightly wraps the finished guardrail 61, thus completing the purpose of automatic packaging of the finished guardrail 61.

[0033] Combination Figure 1 and Figure 4 In one specific embodiment, the conveying component 2 includes: a conveying base 21, a conveying roller 23, and a conveying motor 22; the conveying base 21 is fixedly set on the ground, one end of the conveying base 21 is correspondingly set with the fixed base 11, the conveying roller 23 is rotatably set on the conveying base 21, and multiple sets of the conveying roller 23 are spaced apart along the length direction of the conveying base 21; the conveying motor 22 is fixedly set on the conveying base 21, the output end of the conveying motor 22 passes through the conveying base 21, and the output end of the conveying motor 22 is fixedly connected to one end of the conveying roller 23, and multiple sets of the conveying motor 22 and the conveying roller 23 are correspondingly set.

[0034] In this embodiment, the conveying base 21 is a rectangular frame, and the conveying roller 23 is a cylinder. Both ends of the conveying roller 23 are rotatably connected to the conveying base 21. The output of the conveying motor 22 is not affected by the conveying base 21. A friction pad 52 is fitted onto the conveying roller 23, which increases the friction between the conveying roller 23 and the finished guardrail 61, thereby improving the transmission capacity of the conveying roller 23 to the finished guardrail 61. A bidirectional hydraulic rod 53 is horizontally fixed on the conveying base 21. One side of the bidirectional telescopic rod is parallel to the conveying roller 23 along its length. Positioning shafts 54 are obliquely fixed on both telescopic ends of the bidirectional hydraulic rod 53. The positioning shafts 54 are cylindrical, and positioning pads are fitted onto the positioning shafts 54. The positioning roller 55 is cylindrical, and the positioning shaft 54 ​​and the positioning roller 55 are rotatably connected. The angle between the positioning shaft 54 ​​and the bidirectional hydraulic rod 53 is the same as the angle between the finished guardrail 61 and the conveying base 21. That is, the positioning roller 55 can fit against the finished guardrail 61 to accurately position the finished guardrail 61 and ensure that it is stable and does not deviate during the conveying process. The positioning roller 55 can rotate flexibly around the positioning shaft 54, so that there is roller friction between the positioning roller 55 and the finished guardrail 61, which reduces the influence of the positioning roller 55 on the transmission of the finished guardrail 61. The positioning shaft 54, the bidirectional hydraulic rod 53, the positioning shaft 54 ​​and the positioning roller 55 are arranged in multiple sets along the length of the conveying base 21, thereby improving the conveying stability of the conveying assembly 2.

[0035] In practical use, the staff places the finished guardrail 61 on multiple sets of conveyor rollers 23. The staff starts the conveyor motor 22, which drives the conveyor rollers 23 to rotate synchronously. The conveyor rollers 23 carry the finished guardrail 61 forward smoothly. When the finished guardrail 61 passes the positioning roller 55, the bidirectional hydraulic rod 53 shortens and drives the positioning roller 55 to fit tightly against the finished guardrail 61. The positioning roller 55 clamps and positions the finished guardrail 61. The rotation of the conveyor roller 23 drives the finished guardrail 61 through the packaging component 1 and completes the wrapping of the plastic sheet.

[0036] Combination Figure 1 , Figure 2 and Figure 5In one specific embodiment, the clamping assembly 3 includes: a clamping frame 31, a first telescopic rod 32, a second telescopic rod 33, a fixed motor 34, a rotating shaft 35, a fixed plate 36, and a cutting blade 37; the clamping frame 31 is fixedly mounted on the fixed base 11, the first telescopic rod 32 is horizontally fixedly mounted on the clamping frame 31, the extension direction of the first telescopic rod 32 is parallel to the mounting shaft 16, a first telescopic plate 56 is horizontally fixedly mounted on the extension end of the first telescopic rod 32, and the second telescopic rod 33 is horizontally fixedly mounted on the clamping frame 31, the extension direction of the second telescopic rod 3 ... and a first telescopic plate 56 is horizontally fixedly mounted on the extension end of the first telescopic rod 32, and a first telescopic plate 56 is horizontally fixedly mounted on the extension end of the first telescopic rod 32, the second telescopic rod 33 is horizontally fixedly mounted on the clamping frame 31, and the extension direction of the second telescopic rod 33 is parallel to the mounting shaft 16. Parallel to the mounting shaft 16, a second telescopic plate 57 is horizontally fixedly installed on the telescopic end of the second telescopic rod 33. The second telescopic plate 57 is parallel to the first telescopic plate 56. A fixed motor 34 is horizontally fixedly installed around the clamping frame 31. A rotating shaft 35 is rotatably installed around the clamping frame 31. One end of the rotating shaft 35 is fixedly connected to the output end of the fixed motor 34. A fixed plate 36 is fixedly installed on the rotating shaft 35. Two sets of fixed plates 36 are spaced apart along the length of the rotating shaft 35. A cutting blade 37 is fixedly installed on the end of the first telescopic plate 56 away from the first telescopic rod 32.

[0037] In this embodiment, the clamping frame 31 is rectangular in shape and is fixedly mounted on the end of the fixed base 11 away from the conveying hole 60. The telescopic ends of the first telescopic rod 32 and the second telescopic rod 33 both point towards the conveying hole 60. The first telescopic plate 56 and the second telescopic plate 57 are rectangular in shape. The extension of the first telescopic rod 32 can drive the first telescopic plate 56 into the wrapping range of the plastic sheet, and the extension of the second telescopic rod 33 can drive the second telescopic plate 57 into the wrapping range of the plastic sheet. A fixing block 58 is fixedly mounted on the end of the clamping frame 31 near the conveying hole 60. Two sets of fixing blocks 58 are spaced apart along the length of the clamping frame 31. The fixing blocks 58 and the clamping frame 31 can be integrally formed, welded, or bolted together. This embodiment does not specify a particular method. The output end of the fixing motor 34 passes through the fixing block 58, and the rotation of the output end of the fixing motor 34 is not affected by the fixing block 58. The rotating shaft 35 is cylindrical, and its two ends are rotatably connected to the two sets of fixing blocks 58 respectively. The rotation of the output end of the fixing motor 34 can drive the rotating shaft 35 to rotate synchronously. The fixing plate 36 is L-shaped, and its shorter end is fixedly connected to the rotating shaft 35. The rotation of the shaft 35 drives the two sets of fixing plates 36 to rotate synchronously. The rotation of the fixing plates 36 causes the longer end of the fixing plate 36 to abut against the first telescopic plate 56 and the second telescopic plate 57, thereby clamping and fixing the plastic sheet. The cutting blade 37 is fixedly positioned at the end of the first telescopic plate 56 away from the first telescopic rod 32 and close to the second telescopic plate 57. The cutting blade 37 has its blade angled downwards. When the first telescopic rod 32 shortens and causes the first telescopic plate 56 to return to its original position, the first telescopic plate 56 drives the cutting blade 37 to move synchronously. The cutting blade 37 cuts through the material affected by the second telescopic plate 57 and the fixing plate 36. The plastic sheet held by the second telescopic plate 57 and the fixed plate 36 is connected to the rotating roller 17. When the worker is packaging the next set of guardrail finished products 61, after the packaging component 1 wraps the guardrail finished product 61 once, the first telescopic rod 32 drives the first telescopic plate 56 to reset, and the fixed motor 34 drives the fixed plate 36 to reset. The plastic sheet continues to wrap by relying on the friction force wrapped on the guardrail finished product 61, which reduces the step of the worker manually fixing one end of the plastic sheet to the guardrail finished product 61, reduces the workload of the worker, and improves the working efficiency of the automatic packaging machine for guardrail finished products.

[0038] In practical use, after the packaging component 1 completes the wrapping of the finished guardrail 61, the operator activates the extension of the first telescopic rod 32 and the second telescopic rod 33. The first telescopic rod 32 and the second telescopic rod 33 respectively drive the first telescopic plate 56 and the second telescopic plate 57 into the wrapping range of the packaging component 1, so that the plastic sheet wraps around the lower surfaces of the first telescopic plate 56 and the second telescopic plate 57. The operator then activates the fixed motor 34, which rotates to drive the rotating shaft 35 and the fixed plate 36 to rotate synchronously. The longer end of the fixed plate 36 abuts against the plastic sheet, pressing the plastic sheet tightly onto the first telescopic plate 56 and the second telescopic plate 57. The operator controls the first telescopic rod... When the first telescopic rod 32 shortens, it causes the first telescopic plate 56 to reset. The cutting blade 37 moves synchronously with the first telescopic plate 56 and cuts the plastic sheet. The cut plastic sheet is clamped by the second telescopic plate 57 and the fixing plate 36. When the staff controls the packaging component 1 to wrap the plastic sheet around the next set of guardrail finished products 61, one end of the plastic sheet is fixed. When the other end passes through the packaging component 1 and wraps the guardrail finished product 61 once, the staff controls the second telescopic rod 33 to drive the second telescopic plate 57 to reset. The staff controls the fixing motor 34 to drive the fixing plate 36 to reset, thereby assisting the packaging component 1 to automatically wrap the next set of guardrail finished products 61.

[0039] Combination Figure 1 , Figure 3 and Figure 5 In one specific embodiment, the glue application assembly 4 includes: an industrial glue applicator 41, a dispensing valve 43, a hose 42, a third telescopic rod 44, and a push plate 45. The industrial glue applicator 41 is fixedly mounted on the fixed base 11. The dispensing valve 43 is horizontally fixedly mounted on the first telescopic plate 56. The glue outlet of the dispensing valve 43 points to the side of the first telescopic plate 56 away from the second telescopic plate 57. The industrial glue applicator 41 and the dispensing valve 43 are connected through the hose 42. The third telescopic rod 44 is horizontally fixedly mounted on the fixed base 11. The extension direction of the third telescopic rod 44 is perpendicular to the extension direction of the first telescopic rod 32. The push plate 45 is horizontally fixedly mounted on the extension end of the third telescopic rod 44. The length of the push plate 45 is the same as the length of the rotating roller 17.

[0040] In this embodiment, the industrial glue dispenser 41 can output liquid industrial glue. The industrial glue output by the industrial glue dispenser 41 can be transmitted to the dispensing valve 43 through the hose 42. The dispensing valve 43 can control the flow rate of the industrial glue. The working principle of the industrial glue dispenser 41 and the dispensing valve 43 is prior art in this application embodiment, so the working principle of the industrial glue dispenser 41 and the dispensing valve 43 will not be specifically described in this embodiment. The third telescopic rod 44 drives the push plate 45 to move. A mounting block 59 is fixedly provided on the side of the fixed base 11 near the mounting bracket 12. The block 59 and the fixed base 11 can be integrally formed, welded or bolted together. No specific limitation is made in this embodiment. Two sets of mounting blocks 59 are arranged at intervals along the periphery of the fixed base 11. The third telescopic rod 44 is connected to the fixed base 11 through the two sets of mounting blocks 59. The telescopic end of the third telescopic rod 44 points to the mounting frame 12. The push plate 45 is arranged in a cuboid shape. The upper surface of the push plate 45 is slightly lower than the highest point of the conveying roller 23. That is, the push plate 45 can contact the plastic cloth wrapped on the finished guardrail 61 under the drive of the third telescopic rod 44.

[0041] In practical use, when the first telescopic rod 32 drives the first telescopic plate 56 to shorten, the operator activates the dispensing valve 43. The dispensing valve 43 dispenses adhesive onto the edge of the plastic sheet that connects the plastic sheet to the finished guardrail 61. After the first telescopic rod 32 drives the first telescopic plate 56 to reset, the operator activates the third telescopic rod 44. The third telescopic rod 44 extends and drives the push plate 45 to move closer to the plastic sheet. The push plate 45 contacts the plastic sheet and presses the plastic sheet coated with industrial adhesive onto the plastic sheet that is attached to the finished guardrail 61, so that the plastic sheet wrapped around the finished guardrail 61 is firmly bonded by the industrial adhesive.

[0042] It should be noted that the packaging motor 14, conveyor motor 22, fixed motor 34, first telescopic rod 32, second telescopic rod 33, third telescopic rod 44, bidirectional hydraulic rod 53, industrial glue machine 41, and dispensing valve 43 are electrically connected to an external power source. The automatic packaging machine for the guardrail is equipped with a PLC control panel. The PLC control panel is electrically connected to the packaging motor 14, conveyor motor 22, fixed motor 34, first telescopic rod 32, second telescopic rod 33, third telescopic rod 44, bidirectional hydraulic rod 53, industrial glue machine 41, and dispensing valve 43. The PLC control panel can control the extension and retraction of the first telescopic rod 32, second telescopic rod 33, third telescopic rod 44, and bidirectional hydraulic rod 53, the rotation of the packaging motor 14, conveyor motor 22, and fixed motor 34, the output of industrial glue from the industrial glue machine 41, and the application of glue by the dispensing valve 43.

[0043] The implementation principle of this application is as follows: Workers place the finished guardrail 61 onto multiple sets of conveyor rollers 23. Workers control the bidirectional hydraulic rod 53 to shorten and drive the positioning roller 55 to tightly fit the finished guardrail 61. Workers start the conveyor motor 22, which rotates and drives the conveyor rollers 23 to rotate synchronously. The conveyor rollers 23 move the finished guardrail 61 through the conveying hole 60. Workers fix the plastic sheet on the rotating roller 17 onto the finished guardrail 61. Workers start the packaging motor 14, which rotates and drives the gear 15 to rotate synchronously. The gear 15 rotates and drives the arc-shaped rack. 51 and rotating ring 13 rotate, and rotating ring 13 drives mounting shaft 16 and rotating roller 17 to rotate around the central axis of mounting frame 12. As rotating roller 17 rotates, the plastic sheet on rotating roller 17 detaches and wraps around the surface of finished guardrail 61. After the finished guardrail 61 is wrapped, the worker starts the first telescopic rod 32 and the second telescopic rod 33 to extend and drive the first telescopic plate 56 and the second telescopic plate 57 into the wrapping range of packaging component 1. The plastic sheet wraps around the lower surface of the first telescopic plate 56 and the second telescopic plate 57. The worker starts the fixed motor 34, and the fixed motor 34 rotates to drive the rotating shaft. 35 and the fixing plate 36 rotate synchronously, causing the fixing plate 36 to press and fix the plastic sheet on the lower surface of the first telescopic plate 56 and the second telescopic plate 57. The operator controls the first telescopic rod 32 to shorten and drive the first telescopic plate 56 to return to its original position. At the same time, the operator activates the glue dispensing valve 43 to dispense glue onto the edge of the plastic sheet connecting the plastic sheet to the finished guardrail 61. The cutting blade 37 moves synchronously with the first telescopic plate 56 and cuts the plastic sheet. The cut plastic sheet is clamped by the second telescopic plate 57 and the fixing plate 36. The operator activates the third telescopic rod 44, which extends and drives the push plate 45 to move towards the edge of the guardrail 61. Moving closer to the plastic sheet, the push plate 45 contacts the plastic sheet and presses the plastic sheet coated with industrial adhesive onto the plastic sheet that is attached to the finished guardrail 61, so that the plastic sheet wrapped around the finished guardrail 61 is firmly bonded by the industrial adhesive; when the worker is packaging the next set of finished guardrail 61, after the packaging component 1 wraps the finished guardrail 61 once, the first telescopic rod 32 drives the first telescopic plate 56 to reset, the fixed motor 34 drives the fixed plate 36 to reset, and the plastic sheet continues to wrap around the finished guardrail 61 by relying on the friction force of the plastic sheet wrapped around the finished guardrail 61. The above steps are repeated to complete the continuous automatic packaging of the finished guardrail 61.
