Description

Technical Field

[0001] This invention relates to the field of coil packaging technology, specifically to a mosquito coil packaging production line. Background Technology

[0002] Background technology and existing technical problems: In the logistics and packaging of metal products, especially in the transportation and storage of copper pipes for household air conditioners, mosquito coils have become a widely used packaging form due to their unique spiral winding shape. This form not only saves space but also facilitates bulk transportation. However, when mosquito coils are stacked, the structural strength of the packaging box becomes a key factor affecting overall stability and product protection.

[0003] Traditionally, mosquito coils are packaged by stacking them directly inside cardboard boxes. However, in practice, when multiple boxes are stacked, the pressure on the bottom box mainly comes from the weight of the boxes above. If the structural strength of the box is insufficient to fully support the weight, this weight is directly transferred to the mosquito coil inside, causing the copper tubes to be squeezed, deformed, or even damaged. This situation is particularly prominent in logistics, especially during long-distance transportation and warehousing, making the protection of mosquito coils a bottleneck restricting the industry's development.

[0004] To address the pressure issue of mosquito coils during stacking, the industry has introduced a solution of placing support corners inside the cardboard boxes containing the coils. This enhances the structural rigidity of the boxes, distributes pressure from above, and protects the coils from direct compression. However, this method relies heavily on manual labor, which has significant limitations. Manually placing the support corners is not only labor-intensive and inefficient, but also difficult to ensure that the placement of the support corners is exactly the same in every box due to inconsistencies in manual operation. Summary of the Invention

[0005] The present invention aims to provide a packing production line for mosquito coils to solve the problem of low efficiency caused by the manual placement of support corners inside the carton.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A packing production line for mosquito coil coils includes a packing device for packing mosquito coil coils into cartons, and also includes a bottom support corner placement device, an opening support corner placement device, and a transferor. The bottom support corner placement device is used to place the support corner into the bottom of the cartons, and the opening support corner placement device is used to place the support corner into the opening of the cartons. There are transferors between the bottom support corner placement device and the packing device, and between the packing device and the opening support corner placement device. Both the bottom support corner placement device and the opening support corner placement device include a space mover, a pick-and-place claw installed at the output end of the space mover, and a limiting component for restricting the movement of the cartons.

[0007] Technical principle: The production method of the production line using this solution is as follows: S1. Bottom Support Corner Placement in Carton: First, the space mover in the bottom support corner placement device drives the pick-and-place claw to precisely grasp the support corner and place it in the predetermined position at the bottom of the carton. The restraining component ensures the carton remains stationary during this process, avoiding placement errors caused by carton movement. By precisely controlling the path of the space mover, the support corner can be accurately placed in the predetermined position at the bottom of the carton, providing a stable base for subsequent packing of mosquito coils.

[0008] S2. Mosquito coils are loaded into cartons: Cartons with bottom support corners are transferred to the packing device via a transferor. In this step, the mosquito coils are loaded into the cartons by the packing device, ensuring that the mosquito coils are against the bottom support corners inside the cartons.

[0009] S3. Mouth Support Angle Placement in Carton: The carton containing the mosquito coil is transferred to the mouth support angle placement device by the transferor. In this step, the spatial mover and pick-and-place claws of the mouth support angle placement device function to accurately place the support angle at the mouth of the carton. This process is also carried out with the assistance of the restraining components to ensure the accurate placement of the support angle.

[0010] S4. Sealing: After placing the support corners, seal the carton.

[0011] The technical effects of this solution are as follows: First, the degree of automation is improved: through the automated operation of the bottom support corner insertion device and the mouth support corner insertion device, the automation level of mosquito coil packaging is significantly improved, manual intervention is reduced, labor intensity is reduced, and packing efficiency is improved.

[0012] Secondly, this solution forms a stable frame inside the carton by precisely placing the support angles through the spatial mover, effectively improving the overall strength of the carton.

[0013] Third, quality consistency is guaranteed: the use of automated equipment ensures that the support corners inside each carton are placed in the same position, avoiding the instability of manual operation, improving the consistency of packaging quality, and ensuring that each carton of mosquito coils receives the same level of protection.

[0014] Preferably, as an improvement, the pick-and-place claw includes a proximity driver, a left proximity claw, a right proximity claw, and an elastic pressure block. The proximity driver is used to drive the left and right proximity claws to move away from or closer to each other. The elastic pressure block is located between the left and right proximity claws and is used to press against the support corner.

[0015] Beneficial effect: The purpose of the elastic pressure block is to give the support corner of the carton a force towards the bottom of the carton when the left and right claws move outward from the carton, thereby ensuring that the support corner is placed in the predetermined position each time (the predetermined position is such as the bottom of the carton, for example, so that the mouth support corner is pressed against the mouth of the carton of the mosquito coil tube).

[0016] Preferably, as an improvement, the number of elastic blocks is two, and the two elastic blocks are symmetrical about the support angle.

[0017] Beneficial effects: The use of two symmetrically arranged elastic pressure blocks not only ensures the stability of the support corner during placement, but also applies pressure evenly to ensure that the support corner is accurately positioned in the carton, avoiding displacement or damage caused by excessive pressure on one side, and improving the accuracy and reliability of the support corner placement.

[0018] Preferably, as an improvement, the pick-and-place claw further includes an elastic pressure block driver.

[0019] Beneficial effects: When using this solution, the presence of the elastic block actuator allows the displacement and elastic force of the elastic block to be adjusted.

[0020] Preferably, as an improvement, it also includes a linear drive located between the pick-and-place claw and the output end of the space mover.

[0021] Beneficial effects: By setting up the linear mover, the spatial mover can make initial adjustments to the position of the pick-and-place claw, and then the linear driver can make accurate adjustments to the position of the pick-and-place claw, reducing the difficulty of adjustment.

[0022] Preferably, as an improvement, a rotator is also installed between the linear actuator and the pick-and-place claw. The axis of the output shaft of the rotator is set horizontally, the output direction of the linear actuator is also located in the horizontal plane, and the output direction of the linear actuator is perpendicular to the output shaft of the rotator.

[0023] Beneficial effects: By limiting the rotator and the output shaft of the rotator, as well as the output direction of the linear driver, the support angle can be inserted horizontally, reducing the difficulty of insertion.

[0024] Preferably, as an improvement, it also includes a support corner forming device, which includes a forming rotator, a forming mold, a bending pusher, and a bending pusher. The forming rotator is used to drive the forming mold to rotate. The cross-section of the forming mold is an equilateral triangle. The forming mold is provided with a negative pressure adsorption hole. The bending pusher is located below the forming mold and is located on the side of the central axis of the forming mold. The bending pusher is used to push the bending pusher to move closer to the forming mold to bend the cardboard.

[0025] Beneficial effects: When using this solution, the cardboard is bent using the support corner forming device. When the cardboard needs to be bent into a triangular support corner, the cardboard is first attracted by the negative pressure of the forming mold. Then, the forming rotator is controlled to drive the forming mold to rotate. When the edge of the forming mold is located on the side of the bending pusher, the bending pusher is controlled to drive the bending pusher to move closer to the forming mold, thereby bending the cardboard along the edge of the forming mold. Since the forming mold is an equilateral triangle, the bending method of the other two folds is exactly the same. After the three sides are bent, a complete triangular support corner is formed. After the bending is completed, the space mover drives the pick-and-place claw to remove the formed triangular support corner from the forming mold.

[0026] Preferably, as an improvement, a limiting block is also fixed on the molding die, and a limiting groove is provided between the limiting block and the molding die, with the limiting block fixed at the edge of the molding die.

[0027] Beneficial effects: The setting of the limiting block and limiting groove in this solution allows the cardboard to be positioned using the limiting groove before the first bend, ensuring the consistency of quality for each bend.

[0028] Preferably, as an improvement, the bending pusher includes a pusher seat and a pusher roller, the pusher roller being rotatably connected to the pusher seat.

[0029] Beneficial effects: The bending pusher adopts a push seat and a rotating push roller design, which can reduce frictional resistance during the cardboard bending process and ensure the smoothness of the bending action. At the same time, the rolling characteristics of the push roller can also reduce wear and damage caused by direct friction, ensuring the high quality of support corner forming.

[0030] Preferably, as an improvement, the bending pusher further includes a sliding rod fixed on the pusher seat, the sliding rod being vertically slidably connected to the provided frame, and an elastic element being provided between the frame and the pusher seat.

[0031] Beneficial effects: By setting an elastic element on the bending pusher, and ensuring that before bending the cardboard, the distance between the pushing roller and the rotation axis of the forming mold is greater than the distance from the rotation axis of the forming mold to the forming surface of the forming mold, and the distance between the pushing roller and the rotation axis of the forming mold is less than the distance from the edge of the forming mold to the rotation axis, the forming mold will slowly come into contact with the pushing roller of the bending pusher each time it rotates. By using the contact between the pushing roller and the cardboard, the cardboard is folded tightly against the edge of the forming mold, ensuring the consistency of the forming quality of the triangular support corner.

[0032] The present invention also provides a packing device, including a material placement platform, a pusher, a push plate, a packing platform, and a limiting mechanism. The pusher and the packing platform are fixedly installed. The load-bearing tops of the material placement platform and the packing platform are at the same height. The packing platform is placed on one side of the material placement platform. The push plate is fixed to the output end of the pusher. The limiting mechanism is used to limit the horizontal position of the carton on the packing platform. The packing platform is located on the side of the moving direction of the push plate. The pusher is used to drive the push plate to push the mosquito coil tube on the material placement platform into the carton that is limited by the limiting mechanism.

[0033] Beneficial effects: This solution, through the specific design of the packing device, enables mosquito coils to be quickly and accurately pushed into the cardboard box located on the packing platform. Attached Figure Description

[0063] Cardboard box 60, support angle 70, mosquito coil tray 80, cardboard box opening machine 90, cardboard box lid sealing machine 100, palletizing robot 200.

[0064] Example 1 Example 1 is attached. Figures 1 to 19 As shown.

[0065] Combination Figures 2 to 4A mosquito coil packing production line includes a bottom support corner placement device 10, a packing device 20, and an opening support corner placement device 30 arranged sequentially. A transferor 40 is provided between each pair of adjacent devices. In this embodiment, the transferor 40 adopts a driven roller conveyor line to connect the preceding and following processes. The bottom support corner placement device 10 is used to place the triangular support corner 70 into the bottom of the carton 60. The packing device 20 is used to push the stacked mosquito coils 80 into the carton 60, so that the mosquito coils 80 are tightly attached to the bottom support corner 70. The opening support corner placement device 30 is used to place the support corner 70 into the opening of the carton 60.

[0066] I. Bottom support angle insertion device 10 and mouth support angle insertion device 30 and their structural design Combination Figures 5 to 12 The bottom support corner placement device 10 and the mouth support corner placement device 30 have the same structure. Both are located above the transferor 40 and include a space mover 11, a pick-and-place claw 12 installed at the output end of the space mover 11, and a limiting component 13 for restricting the movement of the carton 60. In this embodiment, triangular support corners 70 are placed at predetermined positions at the bottom of the carton 60 and at predetermined positions at the mouth of the carton 60 where the mosquito coil tube 80 is installed. In this embodiment, to achieve the placement of both support corners 70 at once, two symmetrical pick-and-place claws 12 are installed at the output end of the space mover 11. The output end of the space mover 11 is fixedly connected to a bidirectional driver 14. The bidirectional driver 14 has two outputs, and the two outputs of the bidirectional driver 14 always move in opposite directions. For example, a bidirectional rack and pinion driver 142 is used. Figure 10 As shown, the output of the bidirectional rack and pinion 142 driver is a gear 141, which meshes with the symmetrical racks 142. Each rack 142 is fixed with a pick-and-place claw 12, so that when the motor of the bidirectional rack and pinion 142 drives the gear 141 to rotate, the two pick-and-place claws 12 can move closer or further away from each other as the racks 142 move, thereby realizing the adjustment of the distance between the two pick-and-place claws, which is suitable for the support angle 70 placement requirements of different sized cartons 60.

[0067] In this embodiment, the space mover 11 is a three-dimensional space mover 11 capable of moving along the X-axis, Y-axis, and Z-axis. Of course, the space mover 11 can also be a robot or a robotic arm capable of moving in three-dimensional space.

[0068] A linear driver 15 is provided between each pick-and-place claw 12 and the output end of the bidirectional driver 14. The linear driver 15 is used to drive the pick-and-place claw to move closer to or away from the bottom of the carton 60 after the support angle 70 is aligned with the carton 60, so as to realize the action of putting the support angle 70 into the carton 60.

[0069] Each pick-and-place gripper 12 includes a support base 120, a proximity driver 121, a left proximity gripper 122, a right proximity gripper 123, and an elastic pressure block 124. The support base 120 is mounted on the output end of the linear driver 15. The proximity driver 121 is fixed on the support base 120. The proximity driver 121 is used to drive the left proximity gripper 122 and the right proximity gripper 123 to move away from or towards each other. In this embodiment, the proximity driver 121 is a cylinder-type parallel gripper. The left proximity gripper 122 and the right proximity gripper 123 are respectively fixed on the two output blocks of the parallel gripper.

[0070] Combination Figure 11 and Figure 12 There are two elastic pressure blocks 124, which are symmetrical about the support angle 70 and located between the left abutting claw 122 and the right abutting claw 123. The elastic pressure blocks 124 are used to press on the support angle 70. Before the left and right abutting claws 123 clamp the support angle 70, the two symmetrically arranged elastic pressure blocks 124 press down on the support angle 70 to prevent the support angle 70 from moving, thereby ensuring that the left and right abutting claws 123 accurately pick up the support angle 70. When the support angle 70 is placed in the carton 60, after the left and right abutting claws 123 release the support angle 70, the support angle 70 will be pressed against the carton 60 by the elastic pressure blocks 124, ensuring that the support angle 70 is accurately placed in place.

[0071] The pick-and-place claw 12 also includes an elastic pressure block driver 125 fixedly mounted on the support base 120. The elastic pressure block driver 125 is used to adjust the position of the elastic pressure block 124 to improve the practicality of this embodiment. The driving direction of the elastic pressure block driver 125 is parallel to the deformation direction of the elastic pressure block 124, and the deformation direction of the elastic pressure block 124 is parallel to the moving direction when the support angle 70 is placed into the carton 60.

[0072] Specifically, the elastic block driver 125 is a cylinder. The elastic block driver 125 is fixed on the support base 120. The output end of the elastic block driver 125 is fixed with a U-shaped connecting plate 1251. The two free ends of the U-shaped connecting plate 1251 are equipped with elastic blocks 124. The elastic block 124 includes a block body 1241, a slide rod 1242 fixedly connected to the block body 1241, and a spring sleeved on the slide rod 1242. The slide rod 1242 is slidably connected to the connecting plate 1251, and the spring is located between the block body 1241 and the connecting plate 1251.

[0073] A rotator 16 is also installed between each linear actuator 15 and the pick-and-place claw. The rotator 16 is used to drive the support base 120 of the pick-and-place claw to rotate at an angle. The axis of the output shaft of the rotator 16 is set horizontally, and the output direction of the linear actuator 15 is also located in the horizontal plane, and the output direction of the linear actuator 15 is perpendicular to the output shaft of the rotator 16. By limiting the rotator 16 and the output shaft of the rotator 16 and the output direction of the linear actuator 15, the support angle 70 can be inserted in a horizontal pushing manner, reducing the difficulty of inserting the support angle 70.

[0074] In this embodiment, the rotator 16 includes a rotating seat 161 and a rotating driver 162. The rotating seat 161 is rotatably connected to the output end of the linear driver 15. The rotating driver 162 is a cylinder. The output rod of the cylinder is rotatably connected to the rotating seat 161 at an eccentric position. The rotating driver 162 is installed at the output end of the linear driver 15. The support seat 120 of the pick-and-place claw is fixedly connected to the rotating seat 161.

[0075] Combination Figure 7 The limiting component 13 that restricts the movement of the carton 60 includes a bottom baffle 131 and a side baffle 132. The side baffle 132 and the bottom baffle 131 together limit the horizontal position of the carton 60. The side baffle 132 is perpendicular to the conveying direction of the transferor 40, and the bottom baffle 131 is parallel to the conveying direction of the transferor 40. The side baffle 132 is fixedly connected to the output end of the lifter 133 and is fixed within the clearance area of ​​the transferor 40. In this embodiment, the clearance area of ​​the transferor 40 is the space between adjacent rollers. In this embodiment, the lifter is a cylinder. The lifter controls the rise of the side baffle 132 to prevent the carton 60 from moving to other positions before the support angle 70 is placed, as it is conveyed by the transferor 40. The bottom baffle 131 limits the movement from the bottom outside of the carton 60 (in this embodiment, the bottom baffle 131 is fixed to the transferor 40) to ensure that the carton 60 does not move when the support angle 70 is placed inside the carton 60. After the support angle 70 is placed, the lifter lowers the side baffle 132, making it easier for the carton 60 with the bottom support angle 70 to be sent to the next process under the action of the transferor 40.

[0076] II. Structural Design of Support Angle Forming Device 50 A support corner forming device 50 is provided next to both the bottom support corner placement device 10 and the mouth support corner placement device 30.

[0077] Combination Figures 13 to 19The corner forming device 50 includes a loading platform 51, a material handling robot 52, a forming rotary device, a forming mold 53, a bending pusher 54, and a bending pusher 55. The material handling robot 52 includes a translation module 521, a lifting module 522, a material handling mounting plate 523, and a material handling suction cup 524 mounted on the material handling mounting plate 523. The translation module 521 is fixed to the frame, the lifting module 522 is fixed to the output end of the translation module 521, and the material handling mounting plate 523 is fixed to the output end of the lifting module 522. The material handling suction cup 524 is connected to a negative pressure machine and is fixed to the material handling mounting plate 523. The moving direction of the translation module 521 is the same as the moving direction of the transferor 40. The material handling robot 52 uses the translation module 521 and the lifting module 522 to drive the suction cup to remove the cardboard to be processed from the loading platform 51, and then sends the cardboard to the forming mold 53 for forming.

[0078] A forming rotator is fixedly mounted on the frame and used to drive the forming mold 53 to rotate. The forming mold 53 has an equilateral triangular cross-section and a negative pressure hollow hole 531 inside. The negative pressure hollow hole 531 is connected to multiple negative pressure adsorption holes 532, which are arranged on the outer peripheral surface (i.e., the forming surface) of the forming mold 53. The negative pressure hollow hole 531 is connected to a negative pressure machine. A bending pusher 55 is located below the forming mold 53 and is located on the side of the central axis of the forming mold 53. A bending pusher 54 is fixed on the frame and used to push the bending pusher 55 to move closer to the forming mold 53 to bend the cardboard. In the non-working state, the distance between the bending pusher 55 and the central axis of rotation of the forming mold 53 is greater than the distance from the central axis of rotation of the forming mold 53 to the forming surface of the forming mold 53, and the distance between the bending pusher 55 and the central axis of rotation of the forming mold 53 is less than the distance from the edge of the forming mold 53 to the central axis of rotation.

[0079] To ensure initial positioning when the cardboard is bent, a limiting block 533 is fixed on the forming mold 53. A limiting groove 534 is provided between the limiting block 533 and the forming mold 53. The limiting block 533 is fixed at the edge of the forming mold 53.

[0080] Combination Figures 16 to 19 To prevent the cardboard from breaking during the bending process into a triangular support angle 70, the bending pusher 55 is designed to include a pusher seat 551, a pusher roller 552, a sliding rod fixed on the pusher seat 551, and an elastic element (spring) sleeved on the sliding rod. The pusher roller 552 is rotatably connected to the pusher seat 551, and the sliding rod is vertically slidably connected in the fixed mounting sleeve. The elastic element is located between the fixed sleeve and the pusher seat 551 (in this embodiment, the fixed sleeve is fixed on the housing of the bending pusher 54). The pusher roller 552 is used to contact the cardboard formed by the forming mold 53.

[0081] In this embodiment, the push roller 552 of the bending pusher 55 and the elastic setting can reduce the frictional resistance during the cardboard bending process, reduce wear and damage caused by direct friction, and ensure the smoothness and accuracy of the bending action, thus guaranteeing the high quality of the support angle 70 forming.

[0082] The production method of a mosquito coil coil 80 packaged in this embodiment includes the following steps: S1. Bottom support corner 70 placed in the carton: First, the space mover 11 in the bottom support corner placement device 10 drives the pick-and-place claw 12 to precisely grasp the support corner 70 and place it in a predetermined position at the bottom of the carton 60. The restraining component 13 ensures that the carton 60 remains stationary during this process, avoiding placement errors caused by movement of the carton 60. By precisely controlling the path of the space mover 11, the support corner 70 can be accurately placed in the predetermined position at the bottom of the carton 60.

[0083] S2. Mosquito coil 80 is loaded into a carton: The carton 60 with bottom support corner 70 is sent to the packing device 20 via the transferor 40. In this step, the mosquito coil 80 is loaded into the carton 60 by the packing device 20, ensuring that the mosquito coil 80 abuts against the bottom support corner 70 inside the carton 60.

[0084] S3. Mouth support angle 70 placed in the carton: The carton 60 containing the mosquito coil tube 80 is transferred to the mouth support angle placement device 30 by the transferor 40. In this step, the space mover 11 and the pick-and-place claw 12 of the mouth support angle placement device 30 function to accurately place the support angle 70 at the mouth of the carton 60. This process is also carried out with the assistance of the limiting component 13 to ensure the accurate placement of the support angle 70.

[0085] In steps S1 and S3, after the support angle 70 is placed, the limiting component 13 releases its restriction on the carton 60, and the carton 60 moves to the next process under the transferor 40 (conveyor line). S4. Sealing: After placing the support corners 70, seal the carton 60.

[0086] In steps S1 and S3 above, before the pick-and-place claw picks up the support angle 70, the support angle 70 is shaped by the support angle forming device 50. The shaping of the support angle 70 includes the following steps: D1. The material handling robot 52 removes the cardboard from the loading table 51.

[0087] D2. The picking robot inserts the cardboard into the limiting groove 534 between the forming mold 53 and the limiting block 533, and then the cardboard is fixed by the negative pressure generated by the negative pressure adsorption hole 532. The picking robot then releases the cardboard. In this embodiment, the cardboard is in a horizontal state at this time.

[0088] D3. The forming rotator drives the forming mold 53 to rotate. The direction of rotation is to make the cardboard move closer to the bending pusher 55. During the rotation process, the bending pusher 55 restricts the cardboard from rotating with the forming mold 53. As a result, after the edge of the forming mold 53 crosses the elastic bending pusher 55, the direction of the free end of the cardboard changes.

[0089] D4. Start the bending pusher 54, which drives the bending pusher 55 to move the cardboard toward the forming surface of the forming mold 53 to complete the folding of the cardboard. After the folding is completed, the bending pusher 54 returns to its original state.

[0090] D5. The forming rotator continues to rotate to form another fold in the same way as steps D3-D4, until the cardboard forms a triangle, completing the production of the triangular support angle 70.

[0091] The pick-and-place claw moves to the position of the molding mold 53 under the drive of the space mover 11, and grabs the support corner 70 on the molding mold 53. Then, under the drive of the space mover 11, it removes the support corner 70 from the molding mold 53.

[0092] In this embodiment, the setup of the bottom support corner placement device 10, the boxing device 20, the mouth support corner placement device 30, the transferor 40, and the support corner forming device 50 enables automated boxing of the mosquito coil 80 that needs to be transferred into the support corner 70. The entire process achieves on-the-spot production and use of the support corner 70, automatic placement of the support corner 70, and automatic boxing of the mosquito coil 80, reducing labor intensity and improving boxing efficiency. In addition, the use of a mechanically automated boxing method ensures the consistency of the boxing quality of all products after the production line is debugged.

[0093] Example 2 Combination Figures 20 to 24 Example 2 is used to further refine the design of the packing device 20 in Example 1, as follows: The packing device 20 includes a material placement platform 21, a pusher 22, a push plate 23, a packing platform 24, and a limiting mechanism 25. The pusher 22 and packing platform 24 are fixedly installed. The load-bearing tops of the material placement platform 21 and the packing platform 24 are at the same height. The packing platform 24 is placed on one side of the material placement platform 21. The push plate 23 is fixed to the output end of the pusher 22. The limiting mechanism 25 is used to limit the horizontal position of the carton 60 on the packing platform 24. The packing platform 24 is located to the side of the direction of movement of the push plate 23. The pusher 22 drives the push plate 23 to push the mosquito coil 80 on the material placement platform 21 into the carton 60 limited by the limiting mechanism 25. The packed carton 60 is located on the packing platform 24. The packing platform 24 is a roller conveyor line.

[0094] The specific packing table 24 is provided with a clearance area. The limiting mechanism 25 includes a side limiting component 251 and a bottom limiting component 252. The side limiting component 251 includes a left side limiting component 251 and a right side limiting component 251. The side limiting component 251 is located within the clearance area of ​​the packing table 24. Both the left side limiting component 251 and the right side limiting component 251 include a side limiting baffle 2511 and a limiting baffle lifter 2512 that drives the side limiting baffle 2511 to rise and fall. Both the left side limiting component 251 and the right side limiting component 251 are fixedly installed on the dual-output linear module 253. Mounted on a frame, the dual-output linear module 253 includes a bidirectional threaded screw 2531, a drive motor 2532, a slide rail, and two sliders 2533. The drive motor 2532 and the slide rail are fixed on the frame. The drive motor 2532 drives the screw to rotate. The two sliders 2533 are respectively fixed on different threaded sections of the bidirectional threaded screw 2531. The sliders 2533 are interactively connected to the slide rail. The left side limiting component 251 and the right side limiting component 251 are respectively fixed on the two sliders 2533, so that after the drive motor 2532 of the upper output linear module is started, the left and right side limiting components 251 can move closer or further away from each other.

[0095] The bottom limiting assembly 252 includes a bottom limiting plate 2521 and a fixedly installed translation driver 2522. The bottom limiting plate 2521 is fixed to the output end of the translation driver 2522. The translation driver 2522 is used to drive the bottom limiting plate 2521 closer to or away from the bottom of the carton 60. The moving direction of the bottom limiting plate 2521 is parallel to the pushing direction of the push plate 23.

[0096] To ensure accurate packing of the mosquito coil coils 80, a bottom suction cup 2523 is installed on the bottom limiting plate 2521, allowing the carton 60 to move away from or towards the push plate 23 via the bottom suction cup 2523. A lower cover clearance area is provided on the packing table 24, located in the moving direction of the bottom limiting plate 2521, so that after the carton 60 is pushed by the bottom limiting plate 2521, the lower cover of the carton 60 can fall into the lower cover clearance area. A guide plate 26 is also fixed on the frame, extending above the lower cover clearance area, so that after the carton 60 is pushed towards the guide plate 26, the lower cover can be inserted between the guide plate 26 and the lower cover clearance area, thereby pressing the lower cover down and preventing it from tilting upwards. This ensures that the lower cover does not affect the pushing of the stacked packaging bags into the carton 60.

[0097] To prevent the mosquito coil tray 80 from being pushed in due to the collapse of the wide cardboard box 60 in the middle, an lifting assembly 27 is provided on the frame. The lifting assembly 27 is located above the guide plate 26. The lifting assembly 27 includes an lifting plate 271 and a lifting plate lifter 272 that drives the lifting plate 271 to rise and fall.

[0098] To further ensure the rapid insertion of the mosquito coil 80 after the cardboard box 60 is opened, an upper suction assembly 28 is also included on the frame. The upper suction assembly 28 includes an upper suction cup 281 and a suction cup lifter 282 that drives the upper suction cup 281 to rise and fall. The suction cup lifter 282 and the lifting plate lifter 272 are both fixed on the frame. The upper suction cup 281 is located between the upper lifting plate 271 and the bottom limiting plate 2521. The upper suction cup 281 is used to adhere to the upper surface of the cardboard box 60 to prevent the middle of the upper surface of the cardboard box 60 from collapsing and affecting the insertion of the mosquito coil 80.

[0099] Furthermore, to further automate the process, a feeding conveyor line 29 is installed on the packing device 20. The output end of the feeding conveyor line 29 connects to a material placement table 21, which is a roller conveyor type rotary table. The stacked mosquito coils 80 that need to be packed are transferred from the feeding conveyor line 29 to the material placement table 21, further improving the level of automation.
