Description

Technical Field

[0001] The invention relates to the technical field of wet tissue production equipment, and in particular to a double-swing arm cloth pressing device for wet tissue. Background Art

[0002] Wet wipes are a common hygiene product that not only moisturizes and maintains the skin, but also has the function of disinfection or sterilization, becoming a necessity for more and more people. The raw material for wet wipes is non-woven fabric, which needs to be cut and stacked after soaking, which is completed by the cutting mechanism and the stacking mechanism respectively. The stacking mechanism is mainly used to stack the cut non-woven fabric. The non-woven fabric is pressed down from the conveyor belt by the cloth pressing device and received by the lower receiving plate. After the non-woven fabric on the receiving plate is stacked to the set height, the non-woven fabric on the receiving plate is transferred to the conveyor belt and enters the next process.

[0003] The cloth pressing device in the prior art includes a power mechanism and a cloth pressing rod extending up and down. The non-woven fabric moves in a horizontal direction, and the cloth pressing rod is driven by the power mechanism to press the non-woven fabric to the cloth receiving plate on the lower side. Since the cloth pressing rod is always moving up and down, there is a phenomenon in the cloth pressing process that a stack of non-woven fabrics has just been pressed down, and when the cloth pressing rod is withdrawn upward, the next stack of fabrics has been attached to or even hung on the withdrawn cloth pressing plate, and the staff needs to manually clean the hanging fabric. It can be said that the hanging fabric phenomenon is a common problem that reduces the efficiency of cloth pressing, and also affects the production speed of wet tissues to a certain extent. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a double-swing arm cloth pressing device for wet tissues, so as to solve the technical problem in the prior art that the cloth hanging phenomenon reduces the cloth pressing efficiency and affects the production speed of wet tissues.

[0005] In order to achieve the above-mentioned purpose, the double swing arm cloth pressing device for wet tissue provided by the present invention adopts the following technical scheme:

[0006] Double swing arm cloth pressing device for wet wipes, including:

[0007] A driving mechanism, the driving mechanism is mounted on a frame of the stacking mechanism, and the driving mechanism has a power output end;

[0008] A swing arm structure, the swing arm structure cooperates with the power output end transmission, defines that the non-woven fabric moves from back to front, and the swing arm structure is used to make a reciprocating circular motion from back to front driven by the power output end;

[0009] The cloth pressing plate extends horizontally and is connected to the swing arm structure so as to move synchronously with the swing arm structure.

[0010] The double-swing-arm cloth-pressing device for wet tissues provided by the present invention has the beneficial effect that when the driving mechanism is working, the power output end drives the swing-arm structure to perform a reciprocating circular motion from back to front, and at the same time, the cloth-pressing plate connected to the swing-arm structure moves with the swing-arm structure, and in the process of moving from top to bottom and from back to front, the non-woven fabric is pressed down and stacked.

Belt drive can be used for transmission with a large center distance between the two shafts, so that the two devices that need to be driven together do not need to be installed particularly compactly, providing space for loading and unloading.

[0014] Furthermore, there are two rotating shafts, which are arranged in parallel. Pulleys are provided on both rotating shafts, wherein the two rotating shafts and the rotating shaft close to the driving motor and the output shaft of the driving motor are all driven by belts; each rotating shaft is connected to a swing arm, and the vertical plate is provided between the two swing arms.

Two swing arms are provided, and the two swing arms restrain each other, which can effectively improve the stability of the cloth pressing action of the cloth pressing plate, reduce errors, and ensure production accuracy.

[0015] Furthermore, the swing arm includes a connecting rod and two round tubes integrally arranged at both ends of the connecting rod, one of the round tubes is fixed on the rotating shaft, and the other round tube is interference-fitted with an insertion shaft, and the swing arm structure also includes a transfer piece assembled on the two rotating shafts corresponding to the two swing arms, and the transfer piece includes a connecting plate, the connecting plate extends horizontally, and the two ends of the connecting plate have two sleeves, each sleeve is interference-fitted on the corresponding insertion shaft, and the middle part of the connecting plate is detachably connected to the vertical plate.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0025] like Figure 1 As shown, the double swing arm cloth pressing device for wet tissues comprises:

[0026] A driving mechanism, the driving mechanism is mounted on the rack 1 of the stacking mechanism, and the driving mechanism has a power output end;

[0027] A swing arm structure, the swing arm structure cooperates with the power output end transmission, defines that the non-woven fabric moves from back to front, and the swing arm structure is used to make a reciprocating circular motion from back to front driven by the power output end;

[0028] The cloth pressing plate 2 extends horizontally and is connected to the swing arm structure to move synchronously with the swing arm structure.

[0029] When the driving mechanism is working, the power output end drives the swing arm structure to perform reciprocating circular motion from back to front. At the same time, the cloth pressing plate 2 connected to the swing arm structure moves with the swing arm structure, and the non-woven fabric is pressed down and stacked in the process from top to bottom and from back to front. After completing the pressing action of a stack of cloth, the cloth pressing plate 2 does not return to its original position in the vertical direction, but returns to its original position from back to front along the trajectory of a circular arc. In this way, the next stack of non-woven fabric will not "rear-end" the cloth pressing plate 2 and cause the cloth to hang, and the staff no longer needs to manually clean the hanging cloth, thereby ensuring the smooth and fast operation of the entire production line.

[0030] Specifically, Figures 1 to 3As shown, the driving mechanism is a driving motor 3, which is horizontally arranged on the frame 1, and the output shaft of the driving motor 3 constitutes the power output end. In other embodiments, the driving mechanism may also be a cylinder, and the output shaft of the cylinder constitutes the power output end. In this case, the output shaft of the cylinder may be connected to a connecting rod structure to convert the linear motion of the output shaft of the cylinder into rotational motion.

[0031] like Figures 1 to 3 As shown, the swing arm structure includes a rotating shaft 4, one end of which is in transmission cooperation with the output shaft of the driving motor 3, and the other end is connected to a swing arm 5 and the connection point is located at an eccentric position of the swing arm 5; the swing arm structure also includes a vertical plate 6, which is arranged at one end of the swing arm 5 away from the rotating shaft 4, and the lower end of the vertical plate 6 is connected to the cloth pressing plate 2. Specifically, pulleys 7 are provided on the rotating shaft 4 and the output shaft of the driving motor 3, and the rotating shaft 4 and the output shaft of the driving motor 3 are driven by a belt 8. Belt transmission can be used for transmission with a large center distance between the two shafts, so that the two devices that need transmission cooperation do not need to be installed particularly compactly, providing space for loading and unloading. In other embodiments, gears can also be provided on the rotating shaft and the output shaft of the driving motor, and the two are directly engaged by gears to achieve transmission cooperation.

[0032] In this embodiment, there are two rotating shafts 4, which are arranged in parallel. Pulleys 7 are provided on the two rotating shafts 4, wherein the transmission is transmitted through belts 8 between the two rotating shafts 4 and between the rotating shaft 4 close to the driving motor 3 and the output shaft of the driving motor 3; each rotating shaft 4 is connected with a swing arm 5, and the vertical plate 6 is provided between the two swing arms 5. On the basis of avoiding the phenomenon of hanging cloth, efforts should also be made to improve the stability of the operation of the entire swing arm structure. Two swing arms 5 are provided, and the two swing arms 5 are restrained from each other, which can effectively improve the stability of the cloth pressing action of the cloth pressing plate 2, reduce errors, and ensure production accuracy. In other embodiments, the number of swing arms can also be one, and the swing arm is directly connected to the vertical plate.

[0033] In addition, the swing arm 5 is a dumbbell-type structure, including a connecting rod 501 and two round tubes 502 integrally arranged at both ends of the connecting rod 501, one of the round tubes 502 is fixed on the rotating shaft 4, and the other round tube 502 is interference-fitted with an insertion shaft 503. The swing arm structure also includes a transfer member assembled on the two rotating shafts 4 corresponding to the two swing arms 5, and the transfer member includes a connecting plate 9, which extends horizontally, and has two sleeves 10 at both ends of the connecting plate 9, each sleeve 10 is interference-fitted on the corresponding insertion shaft 503, and the middle part of the connecting plate 9 is detachably connected with the vertical plate 6. The transfer member has two functions. On the one hand, it provides a large enough space for the installation of the vertical plate 6 through the connecting plate 9, which facilitates the loading and unloading of the vertical plate 6; on the other hand, the transfer member better realizes the linkage of the two swing arms 5, and fully guarantees the stability and consistency of the movements of the two swing arms 5. In other embodiments, the swing arm may not be a dumbbell-type structure, but other shapes, such as a gourd-shaped structure with a large end and a small end, wherein the smaller end is fixed on the rotating shaft. Of course, in other embodiments, the transfer member may not be provided. In this case, the vertical plate may be provided to be relatively wider, and two swing arms are respectively connected to both sides of the vertical plate in the width direction.

[0034] like Figure 1 and Figure 2 As shown, the sleeve 10 has the same diameter as the circular tube 502. This is convenient for processing and design during production. It should be noted that the same diameter here means that the inner diameter and outer diameter of the two are the same. In other embodiments, only the inner diameter of the two may be the same to facilitate the installation of the plug shaft, while the outer diameters of the two may be different.

[0035] like Figure 3 As shown, a tensioning wheel 11 is also provided between the two rotating shafts 4, and a belt 8 located between the two rotating shafts 4 is mounted on the tensioning wheel 11. A tensioning shaft 12 passes through the tensioning wheel 11, and the tensioning wheel 11 is rotatably assembled on the outer peripheral surface of the tensioning shaft 12, and the tensioning shaft 12 is used to be fixed on the frame 1. Specifically, the double swing arm cloth pressing device also includes a fixed plate 13, and the fixed plate 13 is used to be fixed on the frame 1, and a strip groove 14 is provided on the fixed plate 13, and the strip groove 14 extends up and down, and the tensioning shaft 12 is detachably installed in the strip groove 14, so that the position of the tensioning shaft 12 in the strip groove 14 can be adjusted in the up and down direction. The tensioning force of the tensioning wheel 11 is adjustable to better adapt to the swinging effect of the swing arm structure. In other embodiments, the strip groove may not be provided, and the position of the tensioning shaft on the fixed plate is fixed.

[0036] It should be noted that if Figures 1 to 4As shown, the use environment of the double-swing arm cloth pressing device for wet tissues provided by the present invention is shown. It can be seen that in the transmission direction of the wet tissues, a cloth width adjustment mechanism 15 is respectively provided at both ends from the back to the front, and the cloth width adjustment mechanism 15 includes a forward and reverse screw 151, and a handle (crank) is provided at one end of the forward and reverse screw 151. The forward and reverse screw 151 has two thread segments with opposite thread rotation directions, and a fixed block is respectively provided on the two thread segments. Each fixed block is connected to a cloth supporting plate 19, and the spacing between the two cloth supporting plates 19 is adjustable. In this way, the spacing between the cloth supporting plates can be adjusted according to the width of the wet tissues finally formed by the non-woven fabric product.

[0037] The lower side of the double-swing-arm cloth pressing device for wet tissues is provided with a cloth receiving plate 17 and a cloth pushing plate 18. When in use, the swing-arm structure presses the non-woven fabric onto the cloth receiving plate 17. When the set number is accumulated, the cloth receiving plate 17 moves downward quickly (the cloth receiving plate 17 is connected to a cylinder that moves up and down), and the cloth pushing plate 18 pushes the non-woven fabric out (the cloth pushing plate 18 is connected to a cylinder that moves left and right), and the cloth pushing plate 18 is retracted, and the non-woven fabric falls on the conveying mechanism 16 (conveying belt), and the non-woven fabric is taken out by the conveying mechanism 16 to enter the next process.

[0038] The working principle of the double-swing-arm cloth-pressing device for wet tissues provided by the present invention is described in detail below in combination with the stacking mechanism: before receiving the non-woven fabric from the previous process, the operator adjusts the distance between the two cloth-holding plates 19 by shaking the handle. After the demand is met, the entire stacking mechanism starts to work, and the non-woven fabric enters the stacking mechanism. After being transported to the lower side of the swing-arm structure one after another, the two swing arms 5 drive the cloth-pressing plate 2 to perform a reciprocating circular motion from back to front through the transfer member, and the non-woven fabric is pressed onto the cloth-receiving plate 17 one after another. After the cloth-pressing plate 2 completes the downward pressing action of a stack of fabrics, it does not return to its original position in the vertical direction, but returns to its original position from back to front along the trajectory of the circular arc. In this way, the next stack of non-woven fabrics will not "rear-end" the cloth-pressing plate 2 to cause the phenomenon of hanging fabrics, and the staff no longer needs to manually clean the hanging fabrics.

[0039] When the non-woven fabrics on the receiving plate 17 are stacked to a set height, the receiving plate 17 moves downward rapidly under the action of the cylinder connected to it, and then the pushing plate 18 pushes the non-woven fabrics on the receiving plate 17 in the left and right directions under the action of the cylinder connected to it. After the pushing plate 18 is retracted, the non-woven fabrics fall onto the conveying mechanism 16 (conveyor belt), and the conveying mechanism 16 takes the non-woven fabrics out to the next process.

[0040] Compared with the prior art, the double-swing-arm cloth pressing device for wet wipes provided by the present invention will not "rear-end" the cloth pressing plate 2 to cause cloth hanging when processing non-woven fabrics, and the staff is no longer required to manually clean the hanging cloth, thereby ensuring the smooth and fast operation of the entire production line, improving the cloth pressing efficiency, and ensuring the production speed of wet wipes, effectively solving the technical problem in the prior art that the cloth hanging phenomenon reduces the cloth pressing efficiency and affects the production speed of wet wipes.

[0041] In the present invention, unless otherwise clearly stipulated and limited, for example, it can be a fixed connection, a detachable connection, or an integrated one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0042] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
