Description

Technical Field

[0001] The present invention relates to the technical field of wet wipes processing, and in particular to a wet wipes slitting device and a use method thereof. Background Art

[0002] Wet wipes are moist paper towels used to wipe the skin. The wet wipes on the market can be roughly divided into two categories. One category is disinfected itself but cannot disinfect other items. It contains skin care ingredients and can only be used for skin moisturizing and maintenance. The other category is disinfectant wipes that are not only disinfected themselves but can also disinfect other items. They can be used to disinfect or sterilize skin abrasions and scratches. The disinfectant or sterilization ingredients are usually indicated on the packaging, but the wet wipes are usually produced as a whole, and then cut by a cutting device before they can be packaged.

[0003] In the automated packaging operation of wet wipes, the first step is to place the neatly stacked wet wipes strips one by one on the conveyor belt. Then, the conveyor belt is responsible for safely transporting these wet wipes strips to the bottom of the slitting mechanism. However, during the transmission process, a significant problem is that the current automated packaging line lacks a structure that can effectively limit the wet wipes strips on both sides for different widths. This defect causes the wet wipes strips to easily shift during transmission. As the transmission continues, the shift gradually accumulates, and eventually the wet wipes layer that reaches the bottom of the slitting mechanism becomes obviously uneven, which has an adverse effect on the subsequent cutting operation and the final appearance of the product.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1 and 5 A wet wipes slitting device in this embodiment is used to limit the position of wet wipes of different widths during transmission to prevent the wet wipes after stacking from deviating during the transmission process;

[0040] Specifically, it includes a mounting frame 1, two Y-axis conveyor belts 2, a supporting plate 3, a limiting structure 4 and a cutting structure 5; the two Y-axis conveyor belts 2 are arranged inside the mounting frame 1 with a front-to-back interval, the supporting plate 3 is installed between the two Y-axis conveyor belts 2, and the limiting structure 4 is arranged on the mounting frame 1.

[0041] In actual setting, the stacked wet wipes are placed on the rear Y-axis conveyor belt 2, and the stacked wet wipes are moved to the bottom of the cutting structure 5 by the operation of the Y-axis conveyor belt 2, and cut by the cutting structure 5. In this process, the two sides of the wet wipes are restricted by the limiting structure 4 to prevent the wet wipes from being offset during the transmission process.

[0042] See also Figure 2-3 In order to limit the two sides of the stacked wet wipes strip layer, the limiting structure 4 in this embodiment includes two support frames 401 straddling the mounting frame 1 along the X-axis, and the two support frames 401 are both located above the rear Y-axis conveyor belt 2;

[0043] At least two connecting plates 402 are installed between the two opposite sides of the two support frames 401, a guide rod 403 is arranged inside the support frame 401 along the X-axis direction, at least three transmission plates 404 are slidably connected to the outer side of the guide rod 403, a limit plate 405 is arranged at the bottom of the transmission plate 404 to fit on the rear Y-axis conveyor belt 2, and a connecting rod 406 is arranged between the two transmission plates 404 located in the same Y-axis direction;

[0044] A driving structure that is transmission-connected to at least three connecting rods 406 is disposed on the connecting plate 402 to drive the connecting rods 406 on the left and right sides and the limiting plates 405 to move in opposite directions or opposite directions.

[0045] In actual use, the driving structure is used to drive the connecting rods 406 on the left and right sides to move toward or away from each other, and at the same time, the transmission plate 404 and the limit plate 405 connected thereto are moved toward or away from each other. At this time, the distance between the two adjacent limit plates 405 is adjusted so that the two adjacent limit plates 405 are simultaneously attached to the two sides of the wet wipes strip layer to limit the wet wipes strip layer.

[0046] It should be noted that in order to ensure that the wet wipes strip layer can move between two adjacent limiting plates 405, a certain gap is retained between the two adjacent limiting plates 405 in this embodiment, and the two adjacent limiting plates 405 are arranged in parallel so that the two adjacent limiting plates 405 are combined to form a transmission channel.

[0047] In actual settings, by retaining the gap between two adjacent limit plates 405, it can be ensured that the wet wipe strip layer can be smoothly moved between these limit plates 405. The transmission channel formed by the combination of adjacent limit plates 405 provides a clear and continuous path for the movement of the wet wipe strip layer, which helps to realize the automated and orderly transmission of the wet wipe strip layer, and improves the operating efficiency and reliability of the overall equipment.

[0048] In detail, in order to facilitate the adjustment of the distance between two adjacent limiting plates 405, the two connecting plates 402 in this embodiment are arranged at intervals on the left and right;

[0049] The driving structure includes first cylinders 407 respectively installed on two connecting plates 402. The output ends of the two first cylinders 407 are transmission-connected with an adjusting plate 408. At least three slide grooves 409 are opened inside the adjusting plate 408; at least three connecting rods 406 are respectively slidably connected inside the at least three slide grooves 409.

[0050] In further detail, the middle slide groove 409 is arranged along the Z-axis direction, the left and right slide grooves 409 are arranged to be symmetrical and inclined, and the adjustment plate 408 is arranged in the middle section of the connecting rod 406.

[0051] During actual use, the output end of the first cylinder 407 is extended and retracted to drive the adjustment plate 408 connected thereto to move up and down, and at the same time, the connecting rods 406 on the left and right sides are respectively moved along the inclined directions of the left and right slide grooves 409, so that the limit plates 405 on the left and right sides move oppositely or oppositely, thereby adjusting the distance between two adjacent limit plates 405.

[0052] Specifically, when the adjustment plate 408 moves downward, the connecting rods 406 on the left and right sides drive the limit plates 405 on the left and right sides to move backwards. Conversely, when the adjustment plate 408 moves upward, the connecting rods 406 on the left and right sides drive the limit plates 405 connected thereto to move towards each other.

[0053] See also Figure 4 In order to cut the wet wipes layer, the cutting structure 5 in this embodiment is arranged on the mounting frame 1 for cutting the wet wipes. The cutting structure 5 includes a frame 501 straddling the mounting frame 1, and a second cylinder 502 is arranged on the frame 501. The output end of the second cylinder 502 passes through and extends to the interior of the frame 501, and a cutting knife 503 is transmission-connected to the output end of the second cylinder 502; the cutting knife 503 is located directly above the supporting plate 3.

[0054] In actual use, after the Y-axis conveyor belt 2 conveys the wet wipes strip layer to the bottom of the slitting knife 503, the output end of the second cylinder 502 operates to push the slitting knife 503 downward to slit the wet wipes strip layer.

[0055] Furthermore, in order to ensure that the slitting knife 503 can effectively cut the wet wipe strip layer, in this embodiment, a square opening for the slitting knife 503 to be inserted is opened inside the carrier plate 3 corresponding to the slitting knife 503 .

[0056] In actual configuration, the square opening is provided so that when the second cylinder 502 pushes the slitting knife 503 to move downward, the bottom end of the slitting knife 503 can pass through the wet wipes layer cake and extend to the inside of the square opening.

[0057] In addition, in order to ensure the stability of the up and down movement of the slitting knife 503, guide rods 504 are installed on both sides of the upper end surface of the slitting knife 503 in this embodiment, and through holes for the two guide rods 504 to pass through are opened inside the frame 501.

[0058] Preferably, in order to serve as a stopper for the cut wet wipes strips and thereby improve the stability when the wet wipes strips are cut, the present embodiment also includes a stopper assembly 6, which includes Y-axis motion modules 601 respectively arranged on the left and right sides of the upper surface of the mounting frame 1, and the two Y-axis motion modules 601 are transmission-connected to the same bracket 602; at least one third cylinder 603 is provided on the upper end surface of the bracket 602, and the output end of the third cylinder 603 is transmission-connected to a baffle 604, and the baffle 604 is located above the front Y-axis conveyor belt 2.

[0059] In actual use, the Y-axis motion module 601 drives the bracket 602 to move forward and backward, and then adjusts the distance between the baffle 604 and the slitting knife 503 to determine the slitting length. In the slitting process, the output end of the third cylinder 603 pushes the baffle 604 to move downward, so that the baffle 604 fits against the upper surface of the front Y-axis conveyor belt 2, and at the same time stops the front side of the wet wipes layer to ensure the neatness of the front side of the wet wipes layer. After the slitting is completed, the output end of the third cylinder 603 retracts and drives the baffle 604 to move upward, so that the slit wet wipes layer is released and transported forward through the front Y-axis conveyor belt 2.

[0060] A method for using a wet wipes cutting device is implemented according to the wet wipes cutting device described above, and comprises the following operating steps:

[0061] S001: placing the stacked wet wipes strips on the rear Y-axis conveyor belt 2, and moving the stacked wet wipes strips to the bottom of the cutting structure 5 through the operation of the Y-axis conveyor belt 2;

[0062] S002: Limit both sides of the wet wipes strip by the limiting structure 4 to prevent the wet wipes strip layer from deviating during the transmission process;

[0063] S003: The driving structure is used to drive the connecting rods 406 on the left and right sides to move toward or away from each other, thereby adjusting the distance between two adjacent limiting plates 405;

[0064] S004: By adjusting the distance between two adjacent limiting plates 405, the two adjacent limiting plates 405 are simultaneously attached to the two sides of the wet wipes strip layer, so as to limit the wet wipes strip layer.
