Description

Technical Field

[0001] The utility model relates to the technical field of wet wipes production, and specifically to a high-efficiency packaging machine. Background Technology

[0002] As a convenient cleaning product, wet wipes are widely used in personal care, household cleaning, medical disinfection and other fields. The function of the wet wipes packaging machine is to cut, spray, fold, bag and seal the wet wipes. However, the wet wipes bag will bulge during packaging, occupying a certain space, and the excess air needs to be discharged during production;

[0003] For example, the Chinese utility model patent with announcement number CN218317734U discloses an air discharge device for wet wipes packaging bags, which belongs to the technical field of air discharge for wet wipes packaging bags. The key points of its technical solution include a device body, a guide mechanism, a flattening mechanism and a wet wipes body. The top of the device body is bolted to the bottom of the flattening mechanism, and the bottom of the flattening mechanism is bolted to the top of the device body. The wet wipes body is placed on the top of the device body, and the top of the wet wipes body contacts the surface of the flattening mechanism, and the surface of the wet wipes body contacts the surface of the guide mechanism. This solves the problem that most of the existing automatic packaging machines discharge excess air inside the wet wipes by flattening with a pressing belt. When the pressing belt contacts the wet wipes package, most of the air inside the wet wipes package will be squeezed out, and some excess air will remain inside, resulting in an unsightly sealing appearance of the wet wipes in the subsequent sealing work, thereby affecting the use effect;

[0004] However, the above scheme can only be applied to the production of wet wipes with constant height. When the specifications of the wet wipes packaging change, for example, the thickness increases, the flattening position will be too low, and the wet wipes are easily damaged or the wet wipes liquid is squeezed out. When the thickness decreases, the flattening mechanism cannot achieve sufficient exhaust effect. In addition, the guide mechanism needs to be adjusted manually when in use, which is inconvenient to use. The guide mechanism can only guide the wet wipes in the horizontal direction. In some special cases, such as when the edge of the wet wipes bag is warped, it is easy for the wet wipes bag to be warped upward from the warped position along the guide block, causing the wet wipes bag to deviate.

Detailed Description of the Embodiment

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figures 1 - 3As shown in the figure, it includes a frame 1, on which a conveyor belt 2 is installed. Angle correction structures are respectively installed on the frame 1 at both sides of the front end of the conveyor belt 2, and a pressure - type exhaust structure is installed above the frame 1. The pressure - type exhaust structure includes an exhaust pressing block 3 arranged above the conveyor belt 2. A number of rollers 4 are installed at the bottom of the exhaust pressing block 3. Several support blocks 7 are installed on both sides of the frame 1. A guiding slide rod 5 is installed above each support block 7. Both sides of the exhaust pressing block 3 are respectively connected with sliders 6, and the sliders 6 are respectively slidably installed on the guiding slide rods 5. Driving electric cylinders 10 are installed upward on both sides of the frame 1. A driving block 12 is installed on the exhaust pressing block 3 directly above the driving electric cylinders 10. A counterweight groove 16 is opened above the exhaust pressing block 3. An upper cover 14 is installed at the mouth of the counterweight groove 16. A number of counterweight blocks 18 are movably arranged in the counterweight groove 16. A number of partition plates 17 are arranged in the counterweight groove 16, and the counterweight groove 16 is divided into several counterweight positions by the number of partition plates 17.

[0027] See Figures 1 - 4 As shown in the figure, the angle correction structure includes a rotating shaft assembly one 19 and a rotating shaft assembly two 21 installed on the frame 1. The rotating shaft assembly two 21 is located at the rear side of the rotating shaft assembly one 19. A correction plate 20 is connected to the rotating shaft assembly one 19. The correction plate 20 is a "V" - shaped plate. An adjusting electric cylinder 22 is installed on the rotating shaft assembly two 21. The telescopic rod of the adjusting electric cylinder 22 is connected to the correction plate 20 through a ball - head connection assembly 23.

[0028] As an optimized solution of the present utility model, the adjusting electric cylinder 22 is set. By extending the adjusting electric cylinder 22, the correction plate 20 can be driven to rotate inwards, thereby adjusting the distance between the two correction plates 20. At the same time, the rotating shaft assembly one 19, the rotating shaft assembly two 21 and the ball - head connection assembly 23 ensure the stability of rotation. The inner side of the "V" - shaped correction plate 20 is inclined downwards. When the wet wipe bag passes through, it will generate a guiding force towards the middle and downwards on the correction plate 20, so as to ensure that the wet wipe bag is located at the center position of the conveyor belt 2 and will not be upturned.

[0029] See Figures 1 - 4 As shown in the figure, a photoelectric sensor 24 is installed on the frame 1 at the front position of the pressure - type exhaust structure. The two sensing heads of the photoelectric sensor 24 are respectively arranged on both sides of the conveyor belt 2. The photoelectric sensor 24 is connected to an external controller.

[0030] As an optimized solution of the present utility model, the photoelectric sensor 24 is set to monitor the wet wipe bag and can send a signal in time when it is found that the wet wipe bag passes through, so that the upper computer can control the operation of the equipment.

[0031] See Figures 1 - 3As shown in the figure, several support blocks 7 are installed with micro shock absorbers 8. At the lower end of the slider 6 directly above the micro shock absorber 8, a wear-resistant block 9 is provided; at the top of the telescopic rod of the driving electric cylinder 10, a flexible top head 11 is installed; on the upper cover 14, a lock catch 15 is installed; at the top of the guiding slide rod 5, a limit block 13 is installed; on the counterweight block 18, a handle is installed.

[0032] As an optimized solution of the present utility model, the micro shock absorber 8 is provided to decelerate the exhaust pressure block 3 when it descends, preventing the impact caused by too fast a fall from exerting excessive pressure on the wet wipe bag, resulting in situations such as the liquid in the wet wipe bag spilling out. The wear-resistant block 9 can withstand the impact and increase the service life of the device; the flexible top head 11 can reduce the friction between its telescopic rod and the driving block 12 when the driving electric cylinder 10 extends; the lock catch 15 can ensure the stable installation of the upper cover 14, and the handle facilitates the taking of the counterweight block 18.

[0033] The working principle and usage process of the present utility model are as follows:

[0034] First, install this device into the production line. Adjust the telescopic length of the adjusting electric cylinder 22 according to the width of the wet wipe bag to be processed, so as to adjust the distance between the two calibration plates 20. Then open the upper cover 14 and select the appropriate number of counterweight blocks 18 according to the actual situation of the wet wipes. Place the counterweight blocks 18 on the counterweight positions in the counterweight grooves 16. According to the set speed of the conveyor belt 2, combined with the distance between the photoelectric sensor 24 and the exhaust pressure block 3, and the time for the exhaust pressure block 3 to descend on the micro shock absorber 8, calculate the delay start time of the driving electric cylinder 10 after the photoelectric sensor 24 emits a signal and set it in the controller. After the wiring is completed, start the device to operate. After the wet wipe bag reaches the conveyor belt 2 and moves forward with the conveyor belt 2, after passing through the calibration plates 20 and being guided by the calibration plates 20, the wet wipe bag is located in the middle of the conveyor belt 2, and then continues to be transported backward. After the wet wipe bag touches the photoelectric sensor 24, the controller receives the signal. After a specified delay, start the driving electric cylinder 10 to extend, jack up the exhaust pressure block 3, and then the driving electric cylinder 10 retracts. Under the action of gravity, the exhaust pressure block 3 automatically slides down along the guiding slide rod 5, and the micro shock absorber 8 decelerates the exhaust pressure block 3. The exhaust pressure block 3 gradually presses on the wet wipe bag on the conveyor belt 2. As the conveyor belt 2 transports the wet wipe bag forward, the roller 4 rotates automatically, and at the same time, the gravity of the exhaust pressure block 3 presses on the wet wipe bag continuously through the roller 4 to press out the air in the wet wipe bag until the wet wipe bag moves out of the range of the exhaust pressure block 3. When the next wet wipe bag arrives, the above process is automatically repeated;

[0035] When it is necessary to change the production speed, recalculate the delay according to the speed of the conveyor belt 2 and make the change.

[0036] It should be understood that the above specific embodiments of the present utility model are only for illustrative explanation or interpretation of the principle of the present utility model, and do not constitute a limitation to the present utility model. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present utility model shall be included within the protection scope of the present utility model. In addition, the appended claims of the present utility model are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
