Description

Technical Field

[0001] This application relates to the field of blow molding, and in particular to a blow molding equipment and a method of using the same. Background Technology

[0002] Blow molding mainly refers to hollow blow molding (also known as blow molding), which is a common method for manufacturing hollow products. It is also one of the most commonly used methods in plastic product processing besides extrusion, injection molding, and compression molding. It is developing rapidly and belongs to the category of secondary molding technology.

[0003] Common blow molding equipment includes a blow molding unit and a feeding unit. The feeding unit consists of a conveyor belt that transports the bottles and a collection box located at one end of the conveyor belt. Multiple bottles are neatly arranged on the conveyor belt, which moves the bottles. When the bottles reach one end of the conveyor belt, a robotic arm places them one by one into the collection box. After the collection box is filled with the first layer of bottles, the robotic arm stacks the bottles one by one on top of the first layer, filling the second layer, and then repeats the above operation until the collection box is full.

[0004] Regarding the aforementioned technologies, since the bottle opening area is smaller than the bottle bottom, when the upper bottles are stacked on top of the lower bottles, the bottle opening can provide a smaller force-bearing point. Since blow-molded bottles are empty and have a small mass, they are unstable during the stacking process and are prone to falling over. It is necessary to manually or with the help of equipment to re-stack the fallen bottles, which affects the stacking efficiency of the bottles. Summary of the Invention

[0005] To improve the stacking efficiency of bottles, this application provides a blow molding equipment and a blow molding process.

[0006] The technical solution provided in this application for a blow molding equipment and its usage method is as follows:

[0007] A blow molding machine includes a frame, a conveyor belt, a drive unit, a clamping and sealing device, a lateral moving device, a collection box, and a longitudinal moving device. The conveyor belt is mounted on the frame, and the drive unit is mounted on the frame to drive the conveyor belt to move intermittently. The conveyor belt has multiple packing straps spaced apart along the conveying direction, which together form a space for inserting bottles, with one end of the space being open. The clamping and sealing device and the collection box are both located at one end of the conveyor belt. The clamping and sealing device is mounted on the lateral moving device to seal the packing straps and clamp the bottles. The longitudinal moving device drives the collection box to move longitudinally, and the lateral moving device moves the clamping and sealing device into the collection box.

[0008] By adopting the above technical solution, multiple packing straps are gathered together and placed sequentially on a conveyor belt. When the conveyor belt stops moving, the prepared bottles are placed within the space formed by the gathered packing straps. A drive device then moves the conveyor belt, carrying the bottles to a clamping and sealing device. When the bottles reach the clamping and sealing device, the conveyor belt stops, the clamping and sealing device clamps the bottles, and simultaneously presses the packing straps against the bottle body, sealing the straps to secure them and reduce the possibility of bottles scattering. After packing, the clamping and sealing device maintains its clamping position on the packing straps, and a lateral movement device moves the clamping and sealing device, stably placing the bound bottles into a collection box. After the bottles are placed in the collection box, both the lateral movement device and the clamping and sealing device return to their original positions for packing and transferring the next group of bottles. Once a row of bottles is placed in the collection box, a longitudinal movement device moves the collection box longitudinally, misaligning the bottles inside with the lateral movement device, thus filling the first layer of the collection box with bound bottles. Then, following the above steps, fill the collection box with bottles. Because the bottles are tightly wrapped with strapping before being placed in the collection box, multiple bottles can be connected into a whole. The overall mass of the bundled bottles increases, and the center of gravity becomes more stable, reducing the possibility of bottles falling and the number of times bottles need to be re-stacking, thereby improving the stacking efficiency of the bottles.

[0009] On the other hand, since multiple bottles are tied together as a whole by a packing strap, it also facilitates subsequent bottling and packaging.

[0010] Optionally, the driving device includes a driving gear, a rotating roller, an incomplete gear, and a first motor. The driving gear and the rotating roller are rotatably connected to both ends of the frame, respectively. The conveyor belt is wrapped around the outer periphery of the driving gear and the rotating roller. The incomplete gear is rotatably connected to the frame and can mesh with the driving gear. The first motor is mounted on the frame to drive the incomplete gear to rotate.

[0011] By adopting the above technical solution, the first motor drives the incomplete gear to rotate continuously, allowing the incomplete gear to mesh intermittently with the drive gear, thus enabling the drive gear to rotate intermittently and achieving intermittent movement of the conveyor belt. On the one hand, when the conveyor belt stops moving, it is convenient to place the bottle stably in the packing strap, and it is also convenient for the clamping and sealing device to seal the packing strap; on the other hand, during the intermittent movement of the conveyor belt, the first motor runs continuously without the need for constant starting and stopping, improving the smoothness of the first motor's operation.

[0012] Optionally, the clamping and sealing device includes a connecting plate, a glue spraying head, a first clamping plate, a second clamping plate, a first cylinder, and a second cylinder. The connecting plate is mounted on a transverse moving device. The first cylinder and the second cylinder are respectively mounted at both ends of the connecting plate. The first cylinder is connected to the first clamping plate, and the second cylinder is connected to the second clamping plate. The first cylinder and the second cylinder are used to drive the first clamping plate to move closer to or further away from each other. The glue spraying head is mounted on the first clamping plate and is used to spray glue onto the packing strap.

[0013] By adopting the above technical solution, when the bottle and the packing strap move between the first clamp and the second clamp, the conveyor belt stops moving, the glue spray head sprays glue onto one end of the packing strap, the first cylinder and the second cylinder drive the first clamp and the second clamp to clamp the bottle, then the first clamp and the second clamp drive the two ends of the open end of the packing strap to move closer to each other, the end of the packing strap soaked in glue first presses against the bottle body closest to the open end, and the other end then approaches the end with glue and comes into contact with the glue, which can easily seal the packing strap, so that the packing strap can bind multiple bottles and improve the stability of the bottles.

[0014] Optionally, the first clamping plate has a first insert rod bent towards one side of the second clamping plate at both ends, and the second clamping plate has a second insert rod bent towards one side of the first clamping plate at both ends. The first insert rod and the second insert rod are staggered, and the glue spray head is correspondingly arranged with the second insert rod.

[0015] By adopting the above technical solution, the glue spray head and the first insert are staggered, so that when the first insert presses against the packing strap, it will not come into contact with the glue on the packing strap; and when the second insert presses against the packing strap, the second insert can accurately press the end of the packing strap without glue onto the glue, so that the packing strap can be quickly stuck together and the sealing efficiency can be improved.

[0016] Optionally, both the first and second clamping plates are provided with springs for driving the packing straps to press against the bottle.

[0017] By adopting the above technical solution, when the first and second clamps are close to the bottle, the spring always exerts a force on the strapping, so that the strapping can be pressed against the bottle body, reducing the gap between the strapping and the bottle body, thereby improving the strapping's fastening effect on the bottle.

[0018] Optionally, the lateral moving device includes a gantry frame, a lateral moving cylinder, a moving plate, and a lifting cylinder. The conveyor belt is located below the gantry frame. The moving plate is movably mounted on the gantry frame. The lateral moving cylinder is mounted on the gantry frame to drive the moving plate to move along the conveying direction. The lifting cylinder is mounted on the moving plate and is used to drive the clamping and sealing device to rise and fall.

[0019] By adopting the above technical solution, after the clamping and sealing device seals the packing strap, it maintains the clamping state of the bottle. At this time, the lifting cylinder drives the bottle to rise, the horizontal moving cylinder drives the bottle to move upward to the collection box, and finally the lifting cylinder drives the bottle to fall until the bottle is stably placed in the collection box. Then the clamping and sealing device releases the bottle, and the lifting cylinder and the horizontal moving cylinder bring it back to its original position.

[0020] Optionally, the longitudinal moving device includes a base, a support plate, a lead screw, and a second motor. The support plate is used to place the collection box. The base has a sliding groove. The lead screw is rotatably disposed in the sliding groove. The support plate has a connecting seat. The connecting seat is slidably connected to the sliding groove and threadedly connected to the lead screw. The second motor is disposed on the base to drive the lead screw to rotate.

[0021] By adopting the above technical solution, the second motor drives the lead screw to rotate, and the slide groove restricts the rotation of the connecting seat. The rotation of the lead screw can drive the connecting seat to move in the slide groove, and the connecting seat drives the receiving plate and the collection box to move, thereby facilitating the separation of the bottles in the collection box from the clamping and sealing device.

[0022] Optionally, the drive device further includes a third motor, which is mounted on the base and used to drive the support plate to rotate.

[0023] By adopting the above technical solution, after the collection box is filled with a layer of bottles, the third motor drives the support plate to rotate 90°, so that the bottles in the adjacent two layers can be laid in an alternating manner, thereby improving the stability of the bottles being stacked in the collection box.

[0024] A method of using a blow molding equipment includes the following steps:

[0025] S1: Loading: Place each of the packing straps onto the conveyor belt in sequence. The drive device drives the conveyor belt to move intermittently. When the packing straps stop, neatly place the formed bottles into the space enclosed by the packing straps. Then the conveyor belt continues to move and moves the bottles toward the clamping and sealing device.

[0026] S2: Packaging. After the bottle is moved to the clamping and sealing device, the conveyor belt stops moving. The clamping and sealing device clamps the bottle and seals the packing strap, thus binding the bottle with the packing strap.

[0027] S3: Handling, the lateral moving device drives the clamping and sealing device to move toward the collection box, the clamping and sealing device clamps the bottle, and then the bottle is placed into the collection box;

[0028] S4: Laying out the collection box. After a row of tied bottles is laid out in the direction of the lateral moving device, the longitudinal moving device drives the collection box to move in a direction perpendicular to the lateral moving device, so that the empty space in the collection box corresponds to the lateral moving device. Then the collection box stops moving. The lateral moving device and the clamping and sealing device continue to lay out a second row of tied bottles in the collection box. The same method is used to continue laying out tied bottles in the collection box until the first layer of the collection box is filled. Then the same method is used to lay out a second layer of tied bottles in the collection box until the collection box is full.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. By bundling multiple bottles together with strapping to form a group of bottles, the overall mass of the bottles is increased, making the center of gravity of the bottles more stable, reducing the possibility of bottles falling, reducing the number of times bottles need to be re-stacked, and improving the stacking efficiency of bottles.

[0031] 2. By setting springs on the first and second clamping plates, the clamping force of the strapping strap on the bottle is increased, the gap between the strapping strap and the bottle is reduced, and thus the stability of the bottles in the same group after packaging is improved;

[0032] 3. By driving the collection box to rotate, adjacent layers of bottles inside the collection box can be staggered, which improves the stability of the bottles inside the collection box. Attached Figure Description

[0045] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0046] Example 1:

[0047] A blow molding equipment, as described above Figure 1 The system includes a frame 1, a conveyor belt 2, a drive unit 3, a clamping and sealing device 4, a lateral moving device 5, and a longitudinal moving device 6. The conveyor belt 2 is mounted on the frame 1, and the drive unit 3, also mounted on the frame 1, drives the conveyor belt 2 to move intermittently. Multiple packing straps 7 are spaced apart along the conveying direction on the conveyor belt 2, forming a space for inserting bottles, with one end of the space being open. The clamping and sealing device 4 and a collection box 9 are both located at one end of the conveyor belt 2. The clamping and sealing device 4, mounted on the lateral moving device 5, seals the packing straps 7 and clamps the bottles. The longitudinal moving device 6 drives the collection box 9 to move longitudinally, and the lateral moving device 5 moves the clamping and sealing device 4 into the collection box 9. Baffles 8 are provided on both sides of the conveyor belt 2, fixed to the frame 1, with the distance between the two baffles 8 slightly larger than the diameter of the bottle. The end of the conveyor belt 2 with the clamping and sealing device 4 does not have a baffle 8.

[0048] The packing straps 7 are arranged in a U-shape and placed sequentially on the conveyor belt 2, with each side of the packing straps 7 abutting against two baffles 8. When the conveyor belt 2 stops moving, a group of blow-molded bottles are placed within the space enclosed by the packing straps 7. Then, the drive device 3 moves the conveyor belt 2, which moves the bottles to the clamping and sealing device 4. The clamping and sealing device 4 clamps the bottles and seals the packing straps 7, thus binding the group of bottles together. After sealing, the clamping and sealing device 4 maintains its clamping position, and the lateral movement device 5 moves the clamping and sealing device 4, placing the bottles into the collection box 9. Once a row of bound bottles is placed in the collection box 9, the longitudinal movement device 6 moves the collection box 9 perpendicular to the conveyor belt, aligning the empty space in the collection box 9 with the lateral movement device 5. The longitudinal movement device 6 then fills the second row of bottles in the collection box 9, and so on, until the bottom of the collection box 9 is filled with bottles. This process is repeated until the collection box 9 is filled with bound bottles. Because the bottles are tied together with the packing straps 7, the bottles in the same group are less likely to scatter, and the center of gravity is more stable, so the bottles can be stably stacked in the collection box 9, which improves the stacking efficiency.

[0049] Reference Figure 1 and Figure 2 The drive unit 3 includes a drive gear 31, a rotating roller 32, an incomplete gear 33, and a first motor 34. The drive gear 31 and the rotating roller 32 are rotatably connected to both ends of the frame 1, respectively. The conveyor belt 2 is wound around the outer periphery of the drive gear 31 and the rotating roller 32. The incomplete gear 33 is rotatably connected to the frame 1 and is located below the drive gear 31. The incomplete gear 33 can mesh with the drive gear 31. The first motor 34 is mounted on the frame 1, and the output shaft of the first motor 34 is coaxially and fixedly connected to the incomplete gear 33. When the incomplete gear 33 is disengaged from the drive gear 31, the conveyor belt 2 stops moving, and the bottle is placed into the packing strap 7, at which point the incomplete gear 33 and the drive gear 31 re-mesh.

[0050] The first motor 34 drives the incomplete gear 33 to rotate, and the incomplete gear 33 intermittently meshes with the drive gear 31, thereby driving the drive gear 31 and the rotating roller 32 to rotate intermittently, realizing the intermittent movement of the conveyor belt 2.

[0051] Reference Figure 3The lateral moving device 5 includes a gantry frame 51, a lateral moving cylinder 52, a moving plate 53, and a lifting cylinder 54. The conveyor belt 2 is located below the gantry frame 51. A moving groove 55 is provided at the upper end of the gantry frame 51, extending along the conveying direction of the conveyor belt 2. The moving plate 53 is slidably connected within the moving groove 55. The lateral moving cylinder 52 is located at the upper end of the gantry frame 51. The fixed end of the lateral moving cylinder 52 is connected to the gantry frame 51, and the telescopic end of the lateral moving cylinder 52 is connected to the moving plate 53 to drive the moving plate 53 to slide within the moving groove 55. The fixed end of the lifting cylinder 54 is connected to the moving plate 53, and the telescopic end is connected to the clamping and sealing device 4.

[0052] Reference Figure 4 The clamping and sealing device 4 includes a connecting plate 40, a spray nozzle 41, a first clamping plate 42, a second clamping plate 400, a first cylinder 43, and a second cylinder 44. The connecting plate 40 is connected to the telescopic end of the lifting cylinder 54. A third cylinder 45 and a connecting rod 46 are respectively provided at the two ends of the connecting plate 40 perpendicular to the conveying direction. The fixed end of the third cylinder 45 is connected to the connecting plate 40, and the telescopic end is connected to the first cylinder 43. The first cylinder 43 is parallel to the conveyor belt 2. The end of the connecting rod 46 away from the connecting plate 40 is connected to the second cylinder 44. The end of the first cylinder 43 away from the third cylinder 45 is connected to the first clamping plate 42. The second cylinder 44 is connected to the second clamping plate 400. The first cylinder 43 and the second cylinder 44 are used to drive the first clamping plate 42 and the second clamping plate 400 to move closer or further apart, and both the first clamping plate 42 and the second clamping plate 400 are parallel to the conveyor belt 2.

[0053] Two first insert rods 47 are bent at both ends of the first clamping plate 42 towards the second clamping plate 400, and one second insert rod 48 is bent at both ends of the second clamping plate 400 towards the first clamping plate 42. A gap is left between the two first insert rods 47 for the second insert rod 48 to be inserted. Specifically, the length of the first insert rod 47 is greater than the length of the second insert rod 48. A glue spray head 41 is provided on the first clamping plate 42 and located between the two first insert rods 47. The nozzle of the glue spray head 41 faces the second clamping plate 400 and is used to spray glue onto the packing strap 7.

[0054] Both the first clamping plate 42 and the second clamping plate 400 are provided with springs 49 on the side that are close to each other, which are used to drive the packing strap 7 to press against the bottle. One end of the spring 49 is fixed on the first clamping plate 42 or the second clamping plate 400, and the other end is set freely.

[0055] When the conveyor belt 2 transports the bottle between the first clamping plate 42 and the second clamping plate 400, the conveyor belt 2 stops moving. The glue spray head 41 sprays glue onto the outside of the packing strap 7. At the same time, the first cylinder 43 and the second cylinder 44 drive the first clamping plate 42 and the second clamping plate 400 closer to the bottle, respectively. Then the spring 49 abuts against the packing strap 7 and, as the first clamping plate 42 and the second clamping plate 400 move, exerts a pushing force on the packing strap 7, reducing the gap between the packing strap 7 and the bottle. The first clamping plate 42 and the second clamping plate 400 continue to move. Since the first insert rod 47 is longer than the second insert rod 48, the first insert rod 47 first abuts against the glue-coated end of the packing strap 7, and makes this end press against the bottle body first. Then the second clamp 400 pushes the other end of the packing strap 7 toward the bottle. Since the second insert 48 is aligned with the nozzle, when the second insert 48 pushes the packing strap 7, it can press the packing strap 7 against the glue at the position corresponding to the glue, so that the packing strap 7 can fully contact the glue and facilitate sealing.

[0056] Reference Figure 5 The longitudinal moving device 6 includes a base 61, a support plate 62, a lead screw 64, and a second motor 65. The support plate 62 is used to place the collection box 9. The base 61 has a groove 67 perpendicular to the conveying direction of the conveyor belt 2. The lead screw 64 is rotatably disposed in the groove 67. The bottom of the support plate 62 has a connecting seat 68, which is slidably connected in the groove 67 and threadedly connected to the lead screw 64. The second motor 65 is disposed on the base 61, and the output shaft of the second motor 65 is coaxially and fixedly connected to the lead screw 64.

[0057] The second motor 65 drives the lead screw 64 to rotate. Through the threaded connection between the lead screw 64 and the connecting seat 68, the bearing plate 62 and the collection box 9 move along the length direction of the slide groove 67.

[0058] After a row of bottles is placed in the collection box 9, the second motor 65 is started. The lead screw 64 then moves the collection box 9, aligning the empty space in the collection box 9 with the lifting cylinder 54, so that the lifting cylinder 54 can fill the bottom layer of the collection box 9 with bottles. Once the bottom layer of the collection box 9 is filled with the tied bottles, the above operation is repeated to fill the second layer of the collection box 9 with the tied bottles, until the collection box 9 is full.

[0059] To facilitate the lateral movement device 5 entering or leaving the collection box 9, grooves 10 are provided on the inner wall of the collection box 9, and the width of the grooves 10 is equal to the width of the connecting plate 40. When the lateral movement device 5 enters the collection box 9, the connecting plate 40 is inserted into the groove 10 and slides within the groove 10, which facilitates the contact between the bottle and the side wall of the collection box 9, reduces the gap between the bottle and the side wall of the collection box 9, thereby reducing the possibility of bottle shaking and further improving the stability of the bottle within the collection box 9.

[0060] The implementation principle of Embodiment 1 of this application is as follows: When the incomplete gear 33 is not meshed with the drive gear 31, the conveyor belt 2 stops moving, making it easier to neatly place the bottle into the packing strap 7. Subsequently, the conveyor belt 2 drives the bottle to move between the first clamping plate 42 and the second clamping plate 400. The glue spraying head 41 sprays glue onto one outer side of the open end of the packing strap 7. The first cylinder 43 and the second cylinder 44 drive the first clamping plate 42 and the second clamping plate 400 to clamp the bottle, so that the glue-soaked end of the packing strap 7 first abuts against the bottle body, and the other end then contacts the glue-soaked end and is clamped by the second clamping plate 400.

[0061] The lifting cylinder 54 raises the connecting plate 40 and the bottle, moving them away from the conveyor belt 2. The lateral movement cylinder 52 moves the lifting cylinder 54 above the collection box 9, causing the bottle to descend and the connecting plate 40 to slide into the groove 10. When the bottom of the bottle contacts the bottom of the collection box 9, the first clamping plate 42 and the second clamping plate 40 move away from the bottle. The lifting cylinder 54 then raises the connecting plate 40 again, and the lateral movement cylinder 52 moves the connecting plate 40 back to the conveyor belt 2.

[0062] Then, the second motor 65 drives the collection box 9 to move, aligning the position of the collection box 9 without bottles with the lifting cylinder 54, so that the tied bottles can be neatly stacked at the bottom of the collection box 9. After the bottom layer of the collection box 9 is filled with bottles, the above operation is repeated to lay a second layer of bottles in the collection box 9 until the collection box 9 is filled with bottles.

[0063] Example 2:

[0064] A method of using the blow molding equipment as described in Example 1 includes the following steps:

[0065] S1: Feeding: Place each packing strap 7 on the conveyor belt 2 in sequence. The drive device 3 drives the conveyor belt 2 to move intermittently. When the packing strap 7 stops, neatly place the prepared bottles into the space formed by the packing strap 7. Then the conveyor belt 2 continues to move and moves the bottles toward the clamping and sealing device 4.

[0066] S2: Packaging. After the bottle is moved to the clamping and sealing device 4, the conveyor belt stops rotating; the clamping and sealing device 4 clamps the bottle and seals the packing strap 7, so that the packing strap 7 binds the bottle.

[0067] S3: Handling, the lateral moving device 5 drives the clamping and sealing device 4 to move along the conveying direction, the clamping and sealing device 4 clamps the bottle, and then puts the bottle into the collection box 9;

[0068] S4: Laying: After a row of tied bottles is laid in the collection box 9 along the direction of the conveyor belt 2, the longitudinal moving device 6 drives the collection box 9 to move in a direction perpendicular to the conveyor belt 2, causing the bottles in the collection box 9 to be misaligned with the lateral moving device 5. Then the collection box 9 stops moving. The lateral moving device 5 and the clamping and sealing device 4 continue to lay a second row of tied bottles in the collection box 9. Using the same method, the tied bottles are laid in the collection box 9 until the first layer of the collection box 9 is filled. Then, the same method is used to lay a second layer of tied bottles in the collection box 9 until the collection box 9 is full.

[0069] Specifically, in step S4, when placing bottles in each layer except for the first column, a gap is left between adjacent columns of bottles for the connecting plate 40 to pass through. First, the first cylinder 43 is activated to move the first clamping plate 42 away from the bottles. Then, the third cylinder 45 is activated to raise the first clamping plate 42, making it higher than the bottles. Subsequently, the second cylinder 44 is activated to move the second clamping plate 400 to push the bottles, pushing the current bottle towards the adjacent column of bottles until the adjacent columns of bottles contact each other, thus reducing the gap between the two adjacent groups of bottles. Finally, the second clamping plate 400 is raised.

[0070] Example 3:

[0071] A blow molding equipment, as described above Figure 6 The difference from Embodiment 1 is that the longitudinal moving device 6 further includes a rotating platform 63 and a third motor 66. The rotating platform 63 is located between the base 61 and the support plate 62. Specifically, the connecting seat 68 is fixed to the bottom of the rotating platform 63, and the support plate 62 is rotatably mounted on the rotating platform 63. The third motor 66 is located inside the rotating platform 63, and the output shaft of the third motor 66 passes through to the upper end of the rotating platform 63 and is fixedly connected to the support plate 62.

[0072] The implementation principle of Embodiment 3 of this application is as follows: After the collection box 9 is filled with a layer of tied bottles, the third motor 66 starts, driving the support plate 62 to rotate the collection box 9 by 90° and then stop. Subsequently, the second motor 65 drives the collection box 9 to move so that one end of the collection box 9 is aligned with the lifting cylinder 54. Then, the second layer of the collection box 9 is also filled with tied bottles by the horizontal moving device 5 and the vertical moving device 6. When laying the third layer, the third motor 66 is used again to rotate the collection box 9 by 90°, and the above operation is repeated until the collection box 9 is full. This allows the bottles in adjacent layers to be staggered, thereby improving the stability of the bottles in the collection box 9.

[0073] Example 4:

[0074] A method of using the blow molding equipment as described in Example 3 differs from that in Example 2 in that step S4 is different:

[0075] S4: Laying: After a row of tied bottles is laid in the collection box 9 along the direction of the conveyor belt 2, the longitudinal moving device 6 drives the collection box 9 to move in a direction perpendicular to the conveyor belt 2, so that the bottles in the collection box 9 are misaligned with the lateral moving device 5, and then the collection box 9 stops moving; the lateral moving device 5 and the clamping and sealing device 4 continue to lay a second row of tied bottles in the collection box 9, and the same method is used to continue laying tied bottles in the collection box 9 until the first layer of the collection box 9 is filled;

[0076] After the first layer of collection box 9 is filled, the third motor 66 starts, driving the support plate 62 and collection box 9 to rotate 90° and then stop. The second motor 65 starts, driving the rotating table 63, support plate 62 and collection box 9 to move until one end of collection box 9 is aligned with lifting cylinder 54. The second layer of collection box 9 is then filled by the horizontal moving device 5 and the vertical moving device 6. After each layer of tied bottles is filled, collection box 9 is rotated 90° and its position is readjusted before a new layer of bottles is laid, until collection box 9 is full.

[0077] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
