Description

Technical Field

[0001] This utility model belongs to the technical field of nursing pad machinery and equipment, specifically relating to a device that can produce extended nursing pads and complete three-fold folding functions. Background Technology

[0002] Everyday nursing pads have a relatively large surface area when unfolded for use, so they need to be folded during production and bagging to facilitate packaging and transportation.

[0003] In traditional folding and wrapping mechanisms, the folding width of the nursing pad is fixed. This means that the folding width of nursing pads of different sizes is uniformly fixed. Therefore, different folding mechanisms of different sizes are required to fold and wrap nursing pads that are folded wider and nursing pads that are folded narrower, which results in a waste of cost.

[0004] Moreover, the extended nursing pads currently produced on the market can reach a length of 2.2-2.5 meters. Therefore, when folding longer nursing pads, manual folding is the primary method. Although this ensures miniaturization, the folding quality and efficiency cannot be guaranteed. Therefore, based on the above-mentioned pain points, the inventor proposed a device specifically designed to automatically fold extended nursing pads. Utility Model Content

[0005] The purpose of this invention is to provide a nursing pad folding and covering mechanism that can be adjusted according to different sizes and specifications of nursing pads.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an extended nursing pad three-fold device, which consists of a folding mechanism and a conveying mechanism. The folding mechanism is characterized by being composed of an L-shaped guide frame transmission mechanism, a U-shaped transmission frame transmission mechanism connected to the L-shaped guide frame transmission mechanism, a slotted guide frame transmission mechanism connected to the other side of the U-shaped transmission frame transmission mechanism, and a right-angle L-shaped guide frame transmission mechanism connected to the other side of the slotted guide frame transmission mechanism.

[0007] An obliquely placed motor device is fixedly installed at the junction of the L-shaped guide frame transmission mechanism and the U-shaped transmission frame transmission mechanism.

[0008] A vertically positioned motor device is fixedly installed at the junction of the U-shaped transmission frame transmission mechanism and the slotted guide frame transmission mechanism.

[0009] An obliquely placed motor device is fixedly installed at the joint between the slotted guide frame transmission mechanism and the right-angle L-shaped guide frame transmission mechanism.

[0010] The L-shaped guide frame transmission mechanism includes an L-shaped guide frame and flat belt transmission devices installed on both the upper and lower sides of the L-shaped guide frame. The flat belts transmit power on the surface of the L-shaped guide frame.

[0011] The U-shaped transmission frame transmission mechanism includes a U-shaped transmission frame, a horizontal mesh belt set on the upper surface of the U-shaped transmission frame, and a flat belt transmission device set on the lower side of the U-shaped transmission frame. The flat belt performs transmission on the lower surface and side surface of the U-shaped transmission frame respectively.

[0012] The slotted guide frame transmission mechanism includes a slotted guide frame and flat belt transmission devices installed on the upper and two sides of the slotted guide frame. The flat belts transmit power on the upper surface and the two side surfaces of the slotted guide frame, respectively.

[0013] The right-angle L-shaped guide frame transmission mechanism includes a right-angle L-shaped guide frame and a flat belt transmission device installed on both sides of the right-angle L-shaped guide frame. The flat belts transmit power on the surface of the right-angle L-shaped guide frame.

[0014] The inclined placement motor device is equipped with an inclined pull tab, and the straight placement motor device is equipped with a horizontal pull tab. The inclined pull tab and the horizontal pull tab are used to pull the nursing pad to fold from its center.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model adds an L-shaped guide frame to the folding and covering mechanism to connect with a U-shaped transmission frame, and the other side of the U-shaped transmission frame connects with a slotted guide frame, and the other side of the slotted guide frame connects with a right-angled L-shaped guide frame. This allows the extended nursing pad (2.2-2.5 meters) to easily complete three centering folds after being guided and transmitted by this series of guide frames of different shapes. The folding device of this utility model is particularly good at folding extended nursing pads, solving the problem that traditional folding and covering mechanisms cannot complete the folding of extended nursing pads (2.2-2.5 meters).

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] This invention is a technical improvement to address the shortcomings of existing folding and covering mechanisms that cannot complete the folding of extended nursing pads (2.2-2.5 meters) and rely entirely on manual folding.

[0034] Please see Figures 1 to 3 As shown, the extended nursing pad three-fold device consists of a folding mechanism A and a conveying mechanism B. Folding mechanism A comprises an L-shaped guide frame transmission mechanism A1, a U-shaped transmission frame transmission mechanism A2 connected to the L-shaped guide frame transmission mechanism A1, a slotted guide frame transmission mechanism A3 connected to the other side of the U-shaped transmission frame transmission mechanism A2, and a right-angled L-shaped guide frame transmission mechanism A4 connected to the other side of the slotted guide frame transmission mechanism A3. The folding mechanism A and the conveying mechanism B are fixedly mounted on the mechanism back plate 5. Folding mechanism A needs to complete three centering folds of the nursing pad; therefore, the design allows for the folding of the nursing pad to be completed smoothly even with an unlimited length, whereas traditional folding equipment cannot complete the folding of extended nursing pads.

[0035] like Figure 2 As shown, an obliquely placed motor device is fixedly installed at the docking point of the L-shaped guide frame transmission mechanism A1 and the U-shaped transmission frame transmission mechanism A2. The oblique placement of the motor device 9 is to facilitate the oblique alignment of the pull tab installed on the motor with the middle part of the nursing pad, so as to complete the first centering folding operation.

[0036] A vertically positioned motor device is fixedly installed at the junction of the U-shaped transmission frame transmission mechanism A2 and the slotted guide frame transmission mechanism A3. The vertical placement of the motor device 9 is also to facilitate the vertical alignment of the pull tabs installed on the motor with the middle part of the nursing pad, so as to complete the second centering and folding operation.

[0037] An obliquely placed motor device is fixedly installed at the joint between the slotted guide frame transmission mechanism A3 and the right-angle L-shaped guide frame transmission mechanism A4. The oblique placement of the motor device 9 is to facilitate the oblique alignment of the pull tab installed on the motor with the middle part of the nursing pad to complete the third centering folding operation.

[0038] The L-shaped guide frame transmission mechanism A1 is combined with the U-shaped transmission frame transmission mechanism A2, the U-shaped transmission frame transmission mechanism A2 is combined with the slotted guide frame transmission mechanism A3, and the slotted guide frame transmission mechanism A3 is combined with the right-angle L-shaped guide frame transmission mechanism A4 to form a three-fold production line. All mechanism components are fixed on the frame back plate 5.

[0039] like Figure 4 and Figure 9As shown, the L-shaped guide frame transmission mechanism A1 includes an L-shaped guide frame 101 and flat belt transmission devices installed on both the upper and lower sides of the L-shaped guide frame 101. The flat belts (102, 103) transmit power on the surface of the L-shaped guide frame 101 respectively; the extended nursing pad is conveyed into the upper surface of the L-shaped guide frame 101.

[0040] like Figure 5 and Figure 10 As shown, the U-shaped transmission frame transmission mechanism A2 includes a U-shaped transmission frame 201, a horizontal mesh belt 203 disposed on the upper surface of the U-shaped transmission frame 201, and a flat belt transmission device disposed on the lower surface of the U-shaped transmission frame 201. The flat belts (202, 204) transmit power on the lower and side surfaces of the U-shaped transmission frame, respectively. After the extended nursing pad is conveyed from the upper surface of the L-shaped guide frame 101, it is further conveyed to the horizontal mesh belt 203. Under the action of the inclined pull plate on the inclined motor device, it is pulled along the middle part of the nursing pad towards the joint between the L-shaped guide frame 101 and the U-shaped transmission frame 201. At this time, the nursing pad, which has been folded for the first time, enters the alignment gap of the joint under the action of the flat belt and continues to be conveyed to the lower surface of the U-shaped transmission frame 201. Under the transmission action of the flat belt, the nursing pad after the first fold continues to be conveyed to the slotted guide frame 301. The horizontal mesh belt 203 is designed to facilitate the placement of the nursing pad on one side during the first fold, so that the first centering fold can be completed here no matter how long the nursing pad is.

[0041] like Figure 6 and Figure 11 As shown, the slotted guide frame transmission mechanism A3 includes a slotted guide frame 301 and flat belt transmission devices installed on the upper and side sides of the slotted guide frame 301. The flat belts (302, 303) transmit power on the upper surface and side surfaces of the slotted guide frame, respectively. When the nursing pad is conveyed to the junction of the slotted guide frame 301 and the U-shaped transmission frame 201, it is pulled along the middle part of the nursing pad towards the upper surface of the slotted guide frame 301 under the action of the transverse pull plate installed on the vertically placed motor device. At this time, the second centering and folding work is completed. Then, under the action of the flat belt, it continues to be conveyed along the upper surface of the slotted guide frame 301 to the junction with the right-angle L-shaped guide frame 401.

[0042] like Figure 7 and Figure 12As shown, the right-angle L-shaped guide frame transmission mechanism A4 includes a right-angle L-shaped guide frame 401 and flat belt transmission devices installed on the sides of the right-angle L-shaped guide frame 401. The flat belts (402, 403) transmit power on the surface of the right-angle L-shaped guide frame 401. After the nursing pad is folded twice, it is conveyed to the junction of the right-angle L-shaped guide frame 401 and the slotted guide frame 301. Under the action of the inclined pull plate on the inclined motor device 9, it is folded again along the middle part of the nursing pad towards the alignment gap between the slotted guide frame 301 and the right-angle L-shaped guide frame 401. Finally, it is conveyed out from the other side of the right-angle L-shaped guide frame 401 and enters the conveying mechanism B. The conveying mechanism B includes a transfer mechanism 6, a transfer wheel 7 and a conveyor belt 8. The nursing pad after being folded three times is finally conveyed out from the conveyor belt 8 for packaging.

[0043] like Figure 8 As shown, the inclined placement motor device is equipped with an inclined pull tab (not shown in the figure), and the straight placement motor device is equipped with a horizontal pull tab (not shown in the figure). The inclined pull tab and the horizontal pull tab are used to pull the nursing pad to fold from its center.

[0044] During operation, the extended nursing pad that needs to be folded is conveyed to the L-shaped guide frame 101 of the L-shaped guide frame transmission mechanism A1, where the first fold is completed at the junction with the U-shaped transmission frame 201; under the transmission action of the flat belt, the nursing pad is conveyed to the junction of the U-shaped transmission frame 201 and the slotted guide frame 301 to complete the second centering fold; under the transmission action of the flat belt, the nursing pad is conveyed to the junction of the slotted guide frame 301 and the right-angle L-shaped guide frame 401 to complete the third centering fold.

[0045] like Figure 2 and Figure 3 As shown, the specific conveying direction of the nursing pad of this utility model is as follows: after the nursing pad is conveyed from the upper end face of the L-shaped guide frame 101, it enters the joint gap between the L-shaped guide frame 101 and the U-shaped transmission frame 201, then passes through the lower end face of the U-shaped transmission frame 201, then passes through the joint gap between the other side of the U-shaped transmission frame and the slotted guide frame 301, then passes through the upper end face of the slotted guide frame 301, then passes through the joint gap between the other side of the slotted guide frame 301 and the right-angled L-shaped guide frame 401, and finally passes through the other side of the right-angled L-shaped guide frame to be conveyed into the transfer mechanism 6, and then from the transfer wheel 7 to the conveyor belt 8 for packaging.

[0046] This invention can automatically and easily fold extended nursing pads (2.2-2.5 meters), with a high degree of automation, and completely replaces the work of traditional folding mechanisms for extended nursing pads that cannot be folded.
