As described in the background art, in order to solve the problem of industrial production, the present invention provides a manufacturing apparatus for an oral cleaning sleeve, as shown in fig. 3, the manufacturing apparatus is a supporting apparatus developed specifically for the oral cleaning sleeve described in the background art, wherein the structure of the oral cleaning sleeve manufactured by the manufacturing apparatus of the present invention is briefly summarized as follows: as shown in fig. 1, the oral cleaning sleeve to be manufactured according to the present invention includes a sleeve portion 1 formed by folding a nonwoven fabric in a first direction and a grip portion 2 integrally extended from the sleeve portion 1, the grip portion 2 being laminated with the sleeve portion 1 in a second direction opposite to the first direction in a packaged state; in the use position, the gripping portion 2 may be deployed from a stacked position to secure the sleeve against removal from a finger or implement.

The sleeve part 1 comprises a working layer 11 and a sleeve layer 12, the working layer 11 and the sleeve layer 12 form a head part 13 at the top end of the cleaning sleeve, and a first side edge 14 and a second side edge 15 are formed at two sides of the cleaning sleeve; after the working layer 11 and the jacket layer 12 are folded, a bonding seam 30 is formed at the positions of the first side edge 14 and the second side edge 15 in an ultrasonic bonding mode; the working layer 11 and the sleeve layer 12 are respectively connected at the head 13 and the first side 14 and the second side 15 to form a sleeve-shaped structure with an insertion opening 20; the sheath layer 12 has an insertion edge 121 opposite the head 13 of the cleaning sheath, which insertion edge 121 forms the mouth edge of the insertion opening 20.

Other structures, functions and functions of the cleaning sleeve are described in detail in CN 107693143 a, which is cited in the background section and incorporated herein in its entirety as part of the present invention. The same reference numerals are used in fig. 1-2 as in the prior art, and in the following detailed description of the manufacturing apparatus, the reference numerals associated with the cleaning sleeve refer to the same structures as in fig. 1 and 2, and if no reference numerals are used, the description of the prior art will be understood by those skilled in the art.

As shown in fig. 3, the manufacturing apparatus for the oral cavity cleaning sleeve of the present invention comprises a first work table 4 and a second work table 5 which are arranged in a right-angle shape and have an L shape, wherein a non-woven fabric feeding roller 41 is arranged at the starting end of the first work table 4, a non-woven fabric cleaning sleeve collecting mechanism 51 is arranged at the tail end of the second work table 5, and a non-woven fabric turn-over opening 6 which forms an included angle of 45 degrees with the length direction of the first work table 4 and the second work table 5 is arranged at the combining part of the first work table 4 and the second work table 5.

The oral cleaning sleeve of the present invention is manufactured to be in a packaged state as shown in fig. 2, which starts with a single piece of non-woven fabric wound around a non-woven fabric supply roller 41, and after the oral cleaning sleeve is manufactured, the oral cleaning sleeve is conveyed to an oral cleaning sleeve collecting mechanism 51 in a single state for subsequent manual collection or further conveyed to an automatic packaging machine by a conveyor belt, and each cleaning sleeve is hermetically packaged by means of, for example, a packaging roll film or a packaging bag. This is a general workflow for converting from one piece of nonwoven fabric to a single cleaning sleeve.

As can be seen from the construction of the oral cleaning sleeve shown in fig. 1-2, the completed cleaning sleeve is in a packaged state, i.e., as shown in fig. 2. The nonwoven fabric is folded once in a first direction to form the sheath portion 1, and the grip portion 2 is folded once more in a second direction opposite to the direction in which the sheath portion 1 is formed to form the packaged state. The folding mechanism with the same principle and structure for the two folds is the simplest and the most cost-effective in terms of the ease of mechanical design. A problem arises that the same folding mechanism is not possible with a nonwoven of the same orientation, folded first in a first direction and folded second in the opposite second direction, so that the invention proposes a construction in which the nonwoven is turned over after the first folding and then folded in the opposite direction a second time with a folding mechanism of the same principle.

In order to realize the purpose of turning over the non-woven fabric, the manufacturing equipment of the invention provides the workbench which is in an L-shaped structure as shown in fig. 3, the first workbench 4 and the second workbench 5 are in a right angle, the non-woven fabric is firstly conveyed along the length direction of the first workbench 4 to the joint part of the first workbench 4 and the second workbench 5, the non-woven fabric passes through the non-woven fabric turn-over opening 6 with an included angle of 45 degrees to return to the upper part of the other side from the bottom of one side through the non-woven fabric turn-over opening 6, the turn-over process of the non-woven fabric is perfectly formed, and then the non-woven fabric can be just continuously conveyed along the. The above process can fully present the principle and process of turning over the non-woven fabric of the present invention from fig. 3, and the turning over can be easily implemented by those skilled in the art with reference to fig. 3 of the present invention, so that the manufacturing process of the cleaning sleeve of the present invention formed by folding the cleaning sleeve in two different directions can be implemented.

In order to facilitate understanding of the structural principle of the manufacturing apparatus of the present invention, the method of manufacturing the cleaning sheet of the present invention, that is, the detailed workflow of converting one nonwoven fabric into a single cleaning sheet, will be described in detail with reference to fig. 4 and 4a to 4 f.

Fig. 4 is a schematic view showing an arrangement of the cleaning sheets to be formed on the nonwoven fabric in a virtual state, that is, two rows of the cleaning sheets are formed on both side edges of the nonwoven fabric along the longitudinal direction of the nonwoven fabric, the two rows of the cleaning sheets are symmetrically arranged with respect to a middle line of the longitudinal direction of the nonwoven fabric, the head 13 of the cleaning sheet faces an edge of the nonwoven fabric, and the insertion edge 121 of the insertion port faces the middle line of the nonwoven fabric. Fig. 4 is only for more clearly illustrating the arrangement of the cleaning sleeves, and in practical cases, the cleaning sleeves are initially unfolded and then are finally formed into two rows by technical means of cutting, folding, ultrasonic bonding and the like.

The general layout of the cleaning pad on the nonwoven fabric is described, and the specific steps of the manufacturing method of the present invention will be further described with reference to fig. 4a to 4f, which respectively show a schematic view of the forming step of the cleaning pad of the present invention, wherein the arrows indicate the conveying direction of the nonwoven fabric.

First, as shown in fig. 4a, both side edges of the nonwoven fabric are cut to form two rows of insertion edges 121 of the mouth portion edge of the cleaning sheet on both sides of the nonwoven fabric, and the excess portion indicated by the dotted line is removed after cutting, and may be recovered by, for example, an edge waste cleaner or the like described later. Of course, it is also possible to further form the openings 21 on the nonwoven fabric for assisting the fixing by inserting fingers (see the prior art CN 107693143 a cited in the background art), and because two rows of cleaning covers are formed, the openings 21 cut on the nonwoven fabric are also two rows.

Then, as shown in fig. 4b, both sides of the nonwoven fabric are folded upward toward the center to form a row of sheath portions 1 of the cleaning sheet laminated with the nonwoven fabric at the bottom on both sides of the nonwoven fabric, respectively. Since fig. 4b shows only a state where the folding is to be completed, the pocket portion 1 is not completely formed yet, and further ultrasonic bonding of both side edges of the pocket portion is required.

Thereafter, as shown in fig. 4c, the folded sleeve portion 1 is ultrasonically bonded along the positions of the first side edge 14 and the second side edge 15 (see fig. 1-2) of the two sides of the sleeve portion 1 of each cleaning sleeve to form a bonding seam 30 (shown by a dotted line), so as to connect the first side edge 14 and the second side edge 15 of the sleeve portion 1 of each cleaning sleeve together.

Then, as shown in fig. 4d, the whole non-woven fabric is turned over, so that the surface of the non-woven fabric with the sleeve portion 1 faces downwards, that is, as shown in fig. 1, the first workbench 4 and the second workbench 5 are provided in an L shape in a right-angle layout, and the combining portion of the first workbench 4 and the second workbench 5 is provided with a non-woven fabric turn-over opening 6 forming an included angle of 45 degrees with the length direction of the first workbench 4 and the second workbench 5. The specific turning steps are as follows: the non-woven fabrics are firstly conveyed along the length direction of the first workbench 4, and then reach the joint part of the second workbench 5, and through the non-woven fabrics turn-over opening 6 with an included angle of 45 degrees, the non-woven fabrics pass through the non-woven fabrics turn-over opening 6 from the bottom of one side and return to the upper part of the other side, so that the turn-over process of the non-woven fabrics is formed, and then the non-woven fabrics can be continuously conveyed along the second workbench 5.

Fig. 4d shows the state of fig. 4c after flipping, with a simple mirroring of the state for ease and clarity of illustration. In practice, in the manufacturing apparatus of the present invention, the nonwoven fabric is turned over through the nonwoven fabric-turning opening 6 with an included angle of 45 degrees, and the turned-over nonwoven fabric becomes a mirror image, and in fact, the two side edges of the nonwoven fabric are exchanged. That is, after the nonwoven is turned over from the first table 4 to the second table 5 through the nonwoven turn-over opening 6, the nonwoven is not only turned over, but also the two sides are reversed, and the transport direction of the nonwoven is also turned over by 90 degrees. Therefore, when the skilled person can understand with reference to the drawings, the slight differences shown in the drawings should be ignored, and the layout of the nonwoven fabric in the actual situation is not necessarily different from that in the drawings.

Then, as shown in fig. 4e, both sides of the nonwoven fabric are folded upward toward the center again to turn the sheath portion 1 of the cleaning sheet formed on both sides of the nonwoven fabric upward to be laminated with the nonwoven fabric on the bottom. In this state, the grip portion 2 of the cleaning sheet is stacked below the sheath portion 1, covering the working layer 11 of the sheath portion 1 of the cleaning sheet in a stacked manner, with the sheath layer 12 of the sheath portion 1 facing upwards (see fig. 1-2 for reference numerals).

Finally, as shown in fig. 4f, each sleeve is cut along its outer edges, cut from the nonwoven and the final excess is removed after cutting.

Further, in order to facilitate the removal of the last excess portion at one time, as shown in fig. 4f, the excess portion of the nonwoven fabric that is not formed into the cleaning sleeve (shown as waste material with a shape similar to a triangle between adjacent cleaning sleeves in fig. 4 f) may be vertically connected with the nonwoven fabric at the bottom by ultrasonic bonding (shown as a dotted line 40 indicating a seam formed by ultrasonic bonding) before each cleaning sleeve is cut from the nonwoven fabric, so that the last excess portion of the nonwoven fabric may be completely connected into a whole and may be removed in a single-step and integrally, for example, may be recovered by a waste recovery mechanism and the like described later. Each individual cut cleaning sleeve can be transported and collected by a cleaning sleeve collecting mechanism for being loaded into a packaging roll film or a packaging bag for sealed packaging by a manual or mechanical mode.

According to the manufacturing and forming method of the cleaning sleeve, the two rows of cleaning sleeves can be formed along the length direction of the non-woven fabric through the steps of overturning and folding on two sides, and the cleaning sleeve in a laminated packaging state can be conveniently and quickly formed according to a set flow, so that the problem of industrial continuous production of the cleaning sleeve can be solved.

By describing the steps of the manufacturing method, the detailed structure of the manufacturing apparatus of the present invention will be described in further detail with reference to fig. 3 and the following drawings.

In the manufacturing apparatus of the present invention shown in fig. 3, the first table 4 is provided with a first folding mechanism 42 for folding the nonwoven fabric supplied from the nonwoven fabric supply roller 41 in the first direction, and the first folding mechanism 42 is used to form the sheath portions 1 of the cleaning sheath on both sides of the nonwoven fabric by first folding in the first direction (step shown in fig. 4 b). Fig. 5 is a schematic structural view showing a principle of a first folding mechanism, and fig. 6 is a partial structural view showing a manufacturing apparatus of the present invention, in which the first folding mechanism and a first ultrasonic bonding mechanism which will be described in detail later are shown.

Specifically, as shown in fig. 5 to 6, the first folding mechanism 42 includes a folding angle iron 421 disposed in the middle of the non-woven fabric and smaller than the width of the non-woven fabric, two sides of the folding angle iron 421 are respectively provided with a folding press 422, and the non-woven fabric is folded toward the middle of the non-woven fabric along the edge of the folding angle iron 421 through the folding press 422 to form the sleeve portion 1 of the cleaning sleeve. The hem angle iron 421 is a bent stainless steel plate, and one end facing the nonwoven fabric feeding is tilted upward to block the nonwoven fabric and unfold the nonwoven fabric. The width of hem angle bar 421 is narrower than the width of non-woven fabrics, therefore the non-woven fabrics that the both sides of hem angle bar 421 surpass can inwards draw in along the surface of hem angle bar 421 slightly, at this moment, plaiting briquetting 422 at hem angle bar 421 both sides just in time can push down the non-woven fabrics that inwards draws in (need artifically to draw in the non-woven fabrics in the back and push down with plaiting briquetting 422 when beginning, under the circumstances of continuous operation, the non-woven fabrics can continuously press in plaiting briquetting 422's below under the circumstances of tensioning), along with the advance of non-woven fabrics, the edge of non-woven fabrics has been pressed down by plaiting briquetting 422 and has been folded into required width. In addition, in order to realize better folding effect, avoid the fold, still be provided with stopper 424 in the outside of hem angle bar 421 for the side that the crease edge hugs closely hem angle bar 421 after the restriction non-woven fabrics is folded removes, thereby can further guarantee that folding edge is neat to have the deviation, be convenient for fold and control folding accuracy, also be convenient for fold the shaping. In addition, in order to press the hemming angle iron 421 against the nonwoven fabric, a pressure block 423 is provided at an upper portion of the hemming angle iron 421, and the pressure block 423 presses the hemming angle iron 421 downward, and a downward pressure thereof may be adjusted by a screw or the like.

Further, referring again to fig. 3, a first ultrasonic bonding means 43 for forming the sheath portion 1 by ultrasonic bonding is provided downstream of the first folding means 42 in the moving direction of the nonwoven fabric, and the first ultrasonic bonding means 43 functions to form the bonding seam 30 of the sheath portion 1 (step shown in fig. 4 c). Fig. 7 shows a schematic structural diagram of the first ultrasonic bonding mechanism 43.

Specifically, the first ultrasonic bonding mechanism 43 includes an ultrasonic wave generating mechanism 431 located below the nonwoven fabric and an ultrasonic die roll 432 located above the nonwoven fabric, and the jacket portion 1 formed after the first folding by the first folding mechanism 42 needs to form the joint line 30 of a specific shape by the ultrasonic bonding mechanism 43 for each shape of the independent cleaning jacket, and thus the ultrasonic die roll 432 of a specific structure needs to be provided.

As can be seen in FIG. 7, the ultrasonic mold roll 432 of the present application is generally roller-shaped and includes a mandrel 4321 having a cylindrical mold sleeve 4322 fixedly disposed thereon, and a plurality of U-shaped projections 433 formed around the cylindrical surface of the mold sleeve 4322, each U-shaped projection 433 corresponding to the shape of the bond line 30 of each cleaning sleeve. The spacing between adjacent U-shaped protrusions 433 is the same as the spacing between adjacent cleaning sleeves designed on the nonwoven fabric. In order to correspond to the two rows of cleaning sleeves on the non-woven fabric, a mold sleeve 4322 is respectively fixedly arranged at two ends of the mandrel 4321 in a penetrating manner. The mold sleeve 4322 integrally extends with a mounting portion 4323, and the diameter of the mounting portion 4323 is smaller than that of the mold sleeve 4322. The mounting portion 4323 is fixed to the spindle 4321 by a screw 4324. Since the diameter of the mounting portion 4323 is smaller than the diameter of the die sleeve 4322, the screw 4324 protruding beyond the mounting portion 4323 does not interfere with the rotation of the die sleeve 4322. As the ultrasonic mold roller 432 rotates, the U-shaped protrusions 433 of the ultrasonic mold roller 432 disposed above the nonwoven fabric press the nonwoven fabric against the surface of the ultrasonic generating means 431 in a rolling manner, and the nonwoven fabric pressed against the surface of the ultrasonic generating means 431 is instantaneously thermally fused and joined together at the position pressed by the U-shaped protrusions 433 in accordance with the ultrasonic energy continuously emitted from the ultrasonic generating means 431. That is, each U-shaped protrusion 433 rolls to press the position of the nonwoven fabric, and the ultrasonic energy continuously emitted from the ultrasonic wave generating means 431 forms the bonding seam 30 of each oral cleaning sleeve on the nonwoven fabric. The techniques for ultrasonic bonding are well known and any suitable ultrasonic bonding equipment may be used for the ultrasonic generating means 431 and is commercially available. The ultrasonic wave mould roller of structure more than this application adopts can be so that the non-woven fabrics at the in-process of carrying, and the roll through ultrasonic wave mould roller continuously forms the joint line on the non-woven fabrics surface to every oral cavity cleaning sleeve, can carry out continuous automated production to current oral cavity cleaning sleeve, has solved the problem from scratch, has reduced the manpower and has participated in, the cost is reduced and the probability of dying fungus, has improved the homogeneity and the reliability of product.

Further, referring again to fig. 3, the second table 5 is provided with a second folding mechanism 52 for folding the nonwoven fabric fed from the nonwoven fabric reversing opening 6 in the second direction, and a second ultrasonic bonding mechanism 53 for bonding the waste materials into one body by ultrasonic bonding is provided downstream of the second folding mechanism 52 in the moving direction of the nonwoven fabric. Preferably, the first folding mechanism 42 and the second folding mechanism 52 have the same structure, so that the cost of the mold can be reduced. Of course, since the edges of the twice-folded nonwoven are different in size, the spacing between the components of the two folding mechanisms will vary depending on the size of the folded edges, and the size of the second folding mechanism 52 will correspondingly decrease as the width of the nonwoven becomes narrower after the first folding.

Further, a cutting mechanism 54 is provided downstream of the second ultrasonic bonding mechanism 53, a waste recovery mechanism 55 is provided downstream of the cutting mechanism 54, and the oral cleaning sleeve collection mechanism 51 is provided downstream of the waste recovery mechanism 55. The blanking mechanism 54 may be any cutting mechanism known in the art, such as a roller-shaped die cutting mechanism, etc. The scrap retrieving mechanism 55 may be a general scrap container or a roller provided with a winding mechanism for winding up cut scrap to reduce volume.

In addition, a circular arc cutting mechanism 44 and an edge waste cleaner 45 may be provided upstream of the first folding mechanism 42. The circular arc cutting mechanism 44 may also adopt a conventional roll-shaped die cutting structure or the like. The edge trash collector 45 is configured to have a main collector body 451 and a duct 452, and suction is generated by the main collector body 451, and the duct is adjacent to the cut edge trash in a circular arc shape, so that the cut edge trash can be sucked away.

Further, a first deviation correcting mechanism 46 is provided upstream of the circular arc cutting mechanism 44. Likewise, a second deviation correction device 56 is arranged between the second folding device 52 and the nonwoven turn-over opening 6. Preferably, the first deviation correcting mechanism 46 and the second deviation correcting mechanism 56 are identical in construction. The deviation rectifier is used for correcting left and right movement and one-way deviation of the non-woven fabric in the processing process and keeping the fabric smooth so as to be beneficial to subsequent operations of trimming, folding and the like. In addition, since the manufacturing apparatus of the present invention has a plurality of different steps, each of which needs to ensure that the position of the structure on the nonwoven fabric is consistent, the edge of the nonwoven fabric can be sensed by a sensor (not shown) to automatically adjust the edge position of the nonwoven fabric. That is, before the step shown in FIG. 4a, i.e., before cutting both side edges of the nonwoven fabric, it is preferable to further include a step of performing a rectification operation on the nonwoven fabric, for example, by the first rectification mechanism 46, on the nonwoven fabric before cutting the side edges. Similarly, before the step shown in fig. 4e, that is, before the two sides of the nonwoven fabric are folded upward toward the middle, it is preferable to further include a step of performing a rectification operation on the inverted nonwoven fabric, for example, a rectification operation on the inverted nonwoven fabric by the second rectification mechanism 56.

FIG. 8 is a partial schematic view of the present invention, showing a schematic view of the first deviation rectification mechanism 46. Specifically, as shown in fig. 3 and 8, the two deviation rectifying mechanisms with the same structure of the present invention each include two rollers 561 arranged in parallel, the two rollers 561 and the connecting frames 562 at the two ends form a movable parallelogram, and the angle deflection of the parallelogram is controlled by a motor (not shown in the figure), so that the position of the non-woven fabric tightened on the two rollers 561 is changed, the edge of the non-woven fabric is maintained within the normal range set by the sensor, and the transmission position of the non-woven fabric can be ensured to be consistent.

In conclusion, the manufacturing and forming method of the invention can carry out continuous automatic production on the existing oral cleaning sleeve, solves the problems from scratch, reduces the participation of manpower, reduces the cost and the probability of bacterial contamination, and improves the uniformity and the reliability of the product.
