Description

Technical Field

[0001] The utility model relates to the field of packaging equipment, and more specifically, it relates to a dual-channel bag-supporting device and a wet wipe packaging equipment. Background Art

[0002] The bag-supporting device is an important component of the wet wipe packaging equipment. Its main function is to support and fix the opening of the packaging bag during the wet wipe packaging process, ensuring that the wet wipes can be accurately and efficiently packaged into the packaging bag.

[0003] Currently, the traditional wet wipe packaging equipment has a simple structure. To save occupied space, a single-channel bag-supporting device is usually adopted, which can only open one wet wipe packaging bag at a time during production, resulting in low efficiency and still having room for improvement. Summary of the Utility Model

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] A dual-channel bag-supporting device includes a mounting plate and a bag-supporting assembly. The bag-supporting assembly includes an active support plate and a driven support plate. A connecting block is rotatably connected to the mounting plate. The active support plate is arranged on the connecting block. The driven support plate is rotatably connected to the mounting plate. It further includes a driving assembly for driving the connecting block to rotate. Two groups of bag-supporting assemblies are arranged on the mounting plate, and the two groups of bag-supporting assemblies are symmetrically arranged. A connecting rod is connected between the connecting block and the driven support plate of the adjacent bag-supporting assembly. The two ends of the connecting rod are respectively rotatably connected to the connecting block and the driven support plate. When the connecting block rotates, the driven support plate of the adjacent bag-supporting assembly is driven to rotate in the same direction through the connecting rod.

[0006] The utility model is further arranged as follows: The driving assembly includes a driving cylinder. A connecting plate is arranged on the piston rod of the driving cylinder. The connecting plate protrudes with a top rod towards the connecting blocks of the two groups of bag-supporting assemblies respectively. A return spring is further arranged between the connecting block and the mounting plate. When the piston rod of the driving cylinder extends, the connecting blocks of the two groups of bag-supporting assemblies are driven to rotate simultaneously through the top rod. When the piston rod of the driving cylinder retracts, the return spring drives the connecting block to rotate back to its original position.

[0007] The utility model is further arranged as follows: A through hole is formed on the mounting plate between the connecting block and the top rod, and the top rod passes through the through hole to abut against the connecting block.

[0008] The utility model is further arranged as follows: The connecting block is L-shaped, specifically including a horizontal part and a vertical part. The rotating shaft of the connecting block is located at the connection of the horizontal part and the vertical part. The top rod abuts against the horizontal part, and the active support plate is arranged on the vertical part.

[0009] The present utility model is further configured such that: a travel limiter is provided on the transverse portion. When the transverse portion is parallel to the mounting plate, the travel limiter is in contact with the mounting plate, thereby preventing the connection block from further rotating.

[0010] The present utility model is further configured such that: it further includes a bracket. The mounting plate is rotatably connected to the bracket. A motor for driving the mounting plate to rotate is provided on the bracket. Two sets of bag-supporting assemblies are provided at both the upper and lower ends of the mounting plate.

[0012] In addition, the present utility model also proposes a wet wipe packaging device, including the above-mentioned double-channel bag-supporting device.

[0013] Compared with the prior art, the present utility model has at least the following advantages:

[0014] 1. The two sets of bag-supporting assemblies are symmetrically arranged. When the driving assembly drives the connection block to rotate, the active support plates of the two sets of bag-supporting assemblies rotate towards each other. At the same time, the driven support plates of each other are driven by the connecting rods to rotate in the same direction, so that the driven support plates and the active support plates clamp or separate, realizing the synchronous control of the two sets of bag-supporting assemblies. Two packaging bags can be opened simultaneously at one time, improving the production efficiency of the packaging equipment.

[0015] 2. Two sets of bag-supporting assemblies are provided at both the upper and lower ends of the mounting plate, and the mounting plate is driven to rotate by a motor, realizing the efficient rotation of the bag-supporting process, reducing the interval time between adjacent bag-supporting processes, and further improving the production efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] First embodiment:

[0025] A double-channel bag-supporting device, such as Figures 1 to 3 As shown, it includes a mounting plate 1 and a bag-stretching assembly 2, the bag-stretching assembly 2 includes an active strut plate 201 and a driven strut plate 202, a connecting block 3 is rotatably connected to the mounting plate 1, the active strut plate 201 is arranged on the connecting block 3, the driven strut plate 202 is rotatably connected to the mounting plate 1, the active plate and the driven plate are inserted into the packaging bag when closed, and the packaging bag opening is stretched open when separated, and also includes a driving assembly 4 for driving the connecting block 3 to rotate, the driving assembly 4 drives the connecting block 3 to rotate, thereby driving the active plate to rotate and open.

[0026] There are two sets of bag-supporting components 2 arranged on the mounting plate 1. The two sets of bag-supporting components 2 are arranged horizontally and symmetrically. The driven plates between the two sets of bag-supporting components 2 face each other, and the driving plates are located on the outside. A connecting rod 5 is connected between the connecting block 3 and the driven supporting plate 202 of the adjacent bag-supporting component 2. The two ends of the connecting rod 5 are respectively rotatably connected to the connecting block 3 and the driven supporting plate 202. When the connecting block 3 rotates, the driven supporting plate 202 of the adjacent bag-supporting component 2 can be driven to rotate in the same direction through the connecting rod 5. One (the first set of driving plate) drives three (the second set of driven plates) to rotate synchronously, and four (the second set of driving plates) drives two (the first set of driven plates) to rotate synchronously.

[0027] The driving component 4 includes a driving cylinder 401. A connecting plate is fixed on the piston rod of the driving cylinder 401. Ejector rods 402 protrude respectively towards the connecting blocks 3 of the two sets of bag-supporting components 2 on the connecting plate. A return spring 403 is also arranged between the connecting block 3 and the mounting plate 1. When the piston rod of the driving cylinder 401 extends, the connecting blocks 3 of the two sets of bag-supporting components 2 are driven to rotate simultaneously through the ejector rods 402. When the piston rod of the driving cylinder 401 retracts, the return spring 403 returns to its original state and drives the connecting block 3 to rotate back to its original position.

[0028] A through hole 6 is opened on the mounting plate 1 and between the connecting block 3 and the ejector rod 402. The ejector rod 402 passes through the through hole 6 and abuts against the connecting block 3. A buffer block 7 is fixed on the side of the connecting block 3 facing the ejector rod 402. The buffer block 7 is made of rubber.

[0029] The connecting block 3 is L-shaped, specifically including a horizontal portion 301 and a vertical portion 302 that are perpendicular to each other. When the return spring 403 is in the initial state, the horizontal portion 301 is parallel to the mounting plate 1. The rotating shaft of the connecting block 3 is located at the connection of the horizontal portion 301 and the vertical portion 302. The ejector rod 402 abuts against the horizontal portion 301. The driving supporting plate 201 is fixed on the vertical portion 302, and the return spring 403 is also fixed on the vertical portion 302.

[0030] A stroke limiting member 8 is arranged on the horizontal portion 301. When the horizontal portion 301 is parallel to the mounting plate 1, the stroke limiting member 8 abuts against the mounting plate 1, so that the connecting block 3 remains parallel to the mounting plate 1 after resetting, preventing the connecting block 3 from continuing to rotate.

[0031] The stroke limiting component includes a mounting block 801 fixed on the horizontal portion 301. A screw rod 802 is threadedly connected to the mounting block 801. The screw rod 802 penetrates through the mounting block 801 and is parallel to the vertical portion 302. A nut 803 is threadedly connected to the screw rod 802. After the nut 803 abuts against the mounting block 801, the screw rod 802 is fixed. After loosening the nut 803, the length of the screw rod 802 passing through the mounting block 801 can be adjusted. The screw rod 802 is used to abut against the mounting plate 1 to limit the rotation of the connecting block 3.

[0032] AsFigure 1 As shown in Figure 4 Figure, it further includes a bracket 9. The mounting plate 1 is rotatably connected to the bracket 9. A motor 10 for driving the rotation of the mounting plate 1 is installed on the bracket 9. The mounting plate 1 is connected to the output shaft of the motor 10, and a speed reducer is further provided between the output shaft of the motor 10 and the mounting plate 1. Two groups of bag-supporting components 2 are provided at both the upper and lower ends of the mounting plate 1. The mounting plate 1 is rectangular, and the rotation axis of the mounting plate 1 is located at the center of the mounting plate 1. When the motor 10 drives the mounting plate 1 to rotate 180°, the bag-supporting components 2 at both the upper and lower ends of the mounting plate 1 exchange positions. After the upper bag-supporting component 2 completes the bag-supporting work, the lower bag-supporting component 2 is rotated up, realizing the efficient rotation of the bag-supporting process and reducing the interval time between adjacent bag-supporting processes.

[0033] The driving component 4 is fixed to the top end of the bracket 9. A stop block 11 is fixed to the end of the bracket 9 away from the driving component 4, that is, the bottom end. The stop block 11 extends towards the mounting plate 1. There is a small gap between the stop block 11 and the mounting plate 1. When the bottom end of the mounting plate 1 inclines inward, the stop block 11 plays a supporting role to prevent the mounting plate 1 from tilting greatly.

[0034] The working process of the present utility model is as follows:

[0035] First, the piston rod of the driving cylinder 401 extends. The ejector rods 402 on both sides push the transverse part 301 of the rotating block outwards, causing the two groups of active plates to rotate inwards. At the same time, the driven plate is driven to rotate towards the active plate through the connecting rod 5, realizing the closing of the bag-supporting component 2. The closed bag-supporting component 2 is inserted into the packaging bag. Subsequently, the driving cylinder 401 drives the ejector rods 402 to retract, and the return spring 403 pulls the rotating block back to its original position, causing the two groups of active plates to rotate outwards. At the same time, the driven plate is driven to rotate away from the active plate through the connecting rod 5, realizing the opening of the bag-supporting component 2, thereby expanding the packaging bag.
