The facial masks in the current market are mainly divided into two types in structure, one type of facial mask is formed by overlapping a layer of non-woven fabric and a layer of pearlized film, and the other type of facial mask is formed by only one layer of non-woven fabric. Because the pearlized film plays a role in supporting the non-woven fabric in the mask, the processing is convenient, the pearlized film is useless in the actual use process, more and more people begin to choose the mask without the pearlized film along with the improvement of the environmental awareness of people, and therefore the mask of the single-layer non-woven fabric has the tendency of slowly replacing the mask with the pearlized film.

Detailed Description

Referring to fig. 1 to 8, the utility model provides a gripping device, include: the device comprises an installation component 1, a twisting component 2 and a material taking component 3; wherein, the twisting component 2 is arranged on the mounting component 1 in a lifting way, and at least two groups of twisting components 21 are arranged on the twisting component; the output ends of all the rubbing components 21 are arranged in a back direction and can stretch along the stacking plane direction of the stacked workpieces; the material taking component 3 is arranged on the twisting component 21 and is provided with a material taking component 31; all the twisting components 2 can drive the corresponding material taking members 31 to be unfolded and take up workpieces, of course, the twisting members 21 can drive the material taking members 31 to twist the workpieces through driving the material taking members 31, so that the workpieces stacked on the uppermost layer can be separated from other workpieces, the material taking members 31 can be driven to move outwards through the cooperation of the twisting members 21, and then the workpieces are unfolded through the interaction of the material taking members 31 and the surfaces of the workpieces, so that the workpieces can be taken up. In the present application, the workpiece is predominantly a sheet-like or layer-like structure, preferably a nonwoven mask, in particular a sheet-like structure with fibers or the like.

Referring to fig. 1 to 5, the rubbing assembly 2 in the present application includes a lifting cylinder 22 downwardly installed on the mounting member 1, a rubbing base 23 disposed at an output end of the lifting cylinder 22, and a mounting bracket 24, all the rubbing members 21 are installed on the rubbing base 23, and the mounting bracket 24 is installed at an output end of the rubbing member 21; at least one mounting position 25 is arranged on the mounting frame 24, and the material taking assembly 3 is mounted on the mounting position 25. The twisting member 21 can be considered as a part that performs a cylinder-like action, and the main function of the lifting cylinder 22 is to bring the entire take-out assembly 3 and therewith the workpiece, so that the selection and stroke of the lifting cylinder 22 is set according to the entire work. However, in order to achieve the above-mentioned action of twisting and separating the workpieces, the material taking assembly 3 is required to be matched in addition to the twisting member 21, which will be explained in detail below and will not be described in detail herein. In this application, the position of the installation position 25 that sets up on the mounting bracket 24 is by certain requirement, and different installation positions 25 have certain installation distance, and the realization of the later stage action of strutting of being convenient for like this.

Furthermore, the material taking assembly 3 comprises a mounting base 32 mounted on the output end of the twisting member 21 and a guide structure 33 arranged on the mounting base 32, and the material taking member 31 is mounted in the guide structure 33 and can move along the guide direction of the guide structure 33; a gap 34 is provided between the take-off member 31 and the guide structure 33. In the application, the material taking assembly 3 can be lifted, so that the height of the twisting member 21 can be adjusted, and the material taking member 31 mounted on the twisting member 21 can move along with the twisting member 21, so that the lifting mechanism on the material taking assembly 3 can drive the twisting member 21 to be pressed into the surface of the workpiece on the uppermost layer. However, it can be known from the general knowledge that, when the material taking member 31 is pressed into an object, the pressure is sufficient, and the inserted portion is continuously shaken, so that the moving space of the pressed portion is gradually increased, and the reaction force of the workpiece to the pressing member is reduced, so that the pressing member can be better inserted into the workpiece, and the pressing member in this embodiment is the working end of the material taking member 31. Therefore, under the condition of the same acting force, the application designs the gap 34 between the material taking member 31 and the guide structure 33, and the material taking member 31 can be well inserted into the workpiece while the twisting member 21 repeatedly twists and separates the workpiece through the gap 34 so as to prepare for the next action. In the present application, the next action is to take up the separated workpiece, i.e. the uppermost nonwoven which has been separated from the nonwoven stack, by the take-off member 31. It should be particularly noted that, if there is no gap 34, the rubbing member 21 may easily rub the workpiece while rubbing the workpiece, and in addition, because of lack of the gap, the relative movement between the material taking member 31 and the guide structure 33 may be affected, so that the rigidity of the material taking member 31 during the movement process is large, the material taking member 31 needs to be inserted into the workpiece, and often needs a large force, and with the gap 34, the material taking member 31 may swing relative to the guide structure 33 during the rubbing movement process of the rubbing member 21, so that the material taking member 31 may be better inserted into the workpiece while extending out of the guide structure 33, and further, the material taking efficiency and success rate are improved.

In order to better bring up the separated workpieces, the workpieces in the present application are non-woven fabrics, and at least two convex structures 311 are arranged at one end of the material taking member 31, which can extend out of the guide structure 33, and the convex structures 311 protrude outwards, so that the material taking member 31 can be driven by a lifting component on the material taking assembly 3 to be inserted into the workpieces conveniently. Of course, even if the convex structure 311 is inserted into the workpiece, the workpiece may fall off. Because the non-woven fabrics that this application was used, non-woven fabrics are by many spacing constitutions that the naked eye is visible, consequently convex structure 311 most advanced lateral wall and/or tip set up hook structure 312, hook structure 312 can hook the surface structure of work piece. The hooking structure 312 makes the fibers on the surface of the workpiece surround the tip of the convex structure 311 after the convex structure 311 is inserted into the surface structure of the workpiece. The fibre on the non-woven fabrics is owing to be vertically and horizontally staggered, consequently gets the material component 31 when lifting unit drive on getting material subassembly 3 and rises, and the in-process of work piece is pulled out to convex structure 311, along with convex structure 311 withdraws from the fibre pit that the work piece surface formed gradually, the fibre owing to elasticity of self must tighten up gradually to a certain extent and backfill the pit that strikes and form, and the fibre of kick-backing must be can interact with hook structure 312, and the fibre can be hung on hook structure 312. In the present application, the hooking structure 312 extends over the side wall and/or the end of the tip of the convex structure 311, so when the hooking structure 312 is located on the side wall of the tip of the convex structure 311, we can consider the convex structure 311 as a pointed cone structure, for example, as shown in fig. 7, in order to better pick up the workpiece, the convex structure 311 may be a polygonal pyramid, and certainly may be a cone structure, except that when a cone structure is adopted, the hooking structure 312 on the cone structure has a relatively poor effect of picking up the workpiece relative to the hooking structure 312 on other polygonal pyramid structures. When the hooking structure 312 is at the end of the tip of the convex structure 311, as shown in fig. 8, it can be regarded that the hooking structure 312 and the tip of the convex structure 311 constitute a sharp hook, so that the fiber can be hooked and the workpiece can be carried.

Referring to fig. 6, as mentioned above, in the present application, the material taking member 31 has at least two convex structures 311 at the same time, such a design can avoid the phenomenon that the material taking member 31 cannot hook fibers on the surface of the workpiece when only one convex structure 311 exists. In addition to the above functions, the present application designs at least two convex structures 311 to have another function, in order to bring up a workpiece, if only the hooking structure 312 is used to hook the fibers on the surface of the workpiece, it is difficult to bring up the whole workpiece, so the twisting member 21 is designed in the present application, the twisting structure not only drives the convex structures 311 to twist the workpiece, but also the plurality of twisting structures can cooperate to pull open the workpiece through the corresponding convex structures 311, and at this time, the fibers around the tips of the convex structures 311 are inevitably deformed by force. Referring to fig. 8, the fibers at the outward side of the tip of the convex structure 311 pointing to the rubbing member 21 are deformed by force and pressed against the surface of the sidewall of the tip of the convex structure 311, and the hooking structure 312 can be well engaged with the deformed fibers, so that the lifting structure can well lift the whole workpiece through the convex structure 311 when lifted.

Referring to fig. 3 to 6, in order to better realize the above actions of inserting and twisting the workpiece, a sliding cavity 35 is provided in the mounting base 32, the guide structure 33 is mounted at the lower end of the sliding cavity 35, a sliding block 36 is provided in the sliding cavity 35, and the mounting end of the material taking member 31 is connected with the sliding block 36; a material taking air cylinder 37 is arranged on the mounting base body 32, and the output end of the material taking air cylinder 37 extends into the sliding cavity 35 and is connected with the sliding block 36. Of course, the mounting base 32 is similar to a frame structure in the present application, and is formed by splicing the upper mounting plate 321, the lower mounting plate 322, and the two vertical plates 323 arranged between the upper mounting plate 321 and the lower mounting plate 322, so that the sliding cavity 35 is formed by splicing the upper mounting plate 321, the lower mounting plate 322, and the vertical plates 323 to form an inner cavity, the slider 36 is slid between the two vertical plates 323, the guiding structure 33 is mounted on the lower mounting plate 322, in the present application, for better guiding, the guiding structure 33 is a guiding cylinder structure, and the material taking member 31 is a rod-shaped structure, so that the material taking member 31 can freely slide in the guiding structure 33.

The material taking cylinder 37 is mainly used for driving the material taking component 31 to be inserted into a workpiece for taking a film, and has another important purpose. Since it has been described above that the twisting component 2 in the present application is provided with a plurality of groups, if there is no material taking cylinder 37, after all the material taking members 31 are inserted into the surface structure of the workpiece, the twisting members 21 cannot twist the workpiece by stretching, so the action of twisting the workpiece can only be that the material taking cylinder 37 on one side lifts the material taking member 31, and the twisting member 21 on the other side drives the material taking member 31 to twist the workpiece by stretching. When the material taking member 31 is lifted by the material taking cylinder 37 on the side after reaching the stroke, the material taking member 31 on the side which is lifted is put down by the corresponding material taking cylinder 37 and inserted into the surface structure of the workpiece, the rubbing member 21 corresponding to the side extends out to drive the workpiece to move backwards, and the rubbing member 21 on the side which has been rubbed before retracts to wait for the next rubbing action or other actions. After the twisting action is finished, all twisting members 21 retract to the basic point and then extend outwards at the same time, all material taking cylinders 37 gradually extend out, and when the twisting members 21 reach a certain stroke, the material taking members 31 are just inserted to a preset depth, and meanwhile, the workpieces are spread to a degree enough to bring the weight of the whole workpiece. At this time, the vertical force of the fibers on the workpiece relative to the acting force of all the hooking structures 312 is greater than or equal to the self-gravity of the workpiece, and the lifting cylinder 22 is lifted to a certain height to wait for the next action.

Referring to fig. 3 to 6, at least two sets of guide structures 33 are provided, the material taking members 31 are correspondingly provided in each set of guide structures 33, and the mounting ends of all the material taking members 31 are mounted on the sliding block 36. Such setting can avoid to a certain extent that single material component 31 of getting on same material subassembly 3 can't effectively snatch the condition of work piece to appear. Certainly, in order to better perform the action, a shoulder is arranged on the outer wall of the lower portion of the material taking component 31, an elastic part 38 is arranged between the shoulder and the sliding block 36, specifically, the elastic part 38 is a spring, and is sleeved outside the material taking component 31, and two ends of the elastic part are respectively connected with the shoulder and the sliding block 36, so that the material taking cylinder 37 can be effectively prevented from being in hard contact with a workpiece when being extended, and a certain damping effect is achieved.

The gripping device is provided with the rubbing component 2 which can be lifted, so that the gripping device can adapt to non-woven fabric stacking layers with different heights, and the flexibility of taking and placing is improved; secondly, by utilizing the characteristic that a plurality of groups of twisting members 21 can stretch, the material taking member 31 can be well driven to twist and separate the non-woven fabrics on the uppermost layer of the non-woven fabric stack, and the characteristic that the output ends of all the twisting members 21 are arranged back to back can not only twist the non-woven fabrics, but also stretch the non-woven fabrics, so that the material taking member 31 can take up the separated non-woven fabrics. The gripping device has simple structure, and can well separate and take the non-woven fabric.

Referring to fig. 1 and 9, the present invention further provides a transfer mechanism, which comprises a receiving assembly 4 and the gripping device; the receiving assembly 4 is used for receiving the workpieces carried by the material taking assembly 3 and moving the workpieces away from the material taking assembly 3.

When the gripping device successfully separates the workpiece from the workpiece stack, the linear module 41 drives the material receiving arm 42 to drive the clamping unit 44 and the material receiving plate 43 to move to the vicinity of the gripping device, that is, to one side of the material taking assembly 3, because the lifting height of the material taking assembly 3 is related to the heights of the clamping unit 44 and the material receiving plate 43, after the material receiving arm 42 moves to the right position, the clamping unit 44 moves relative to the material receiving plate 43 to clamp the workpiece separated by the material taking assembly 3. The design of the projecting tongues 45 is effective in ensuring that the receiving plate 43 is inserted well below the workpiece and that the workpiece can be better slid out of or withdrawn from the receiving plate 43 later on when the entire receiving assembly 4 is being blanked.

Further, in the present application, a specific embodiment of the clamping unit 44 is given, wherein the material receiving arm 42 is provided with a first mounting block 47 and a second mounting block 48, the clamping unit 44 comprises a clamping cylinder 441, a lever arm 442 and a jacking head 443, one end of the clamping cylinder 441 is mounted on the first mounting block 47 through a first rotating shaft, and the other end of the clamping cylinder 441 is hinged with one end of the lever arm 442; the middle part of the lever arm 442 is mounted on the second mounting block 48 through a second rotating shaft, and the top pressing head 443 is mounted at the other end of the lever arm 442 with adjustable extension length; the ejector 443 corresponds in position to the projecting tongue 45; the second mounting block 48 is provided with a U-shaped plate 49, the U-shaped plate 49 surrounds the top pressing head 443 and forms a protective frame, and the lever arm 442 can drive the top pressing head 443 to swing around the second rotating shaft and cooperate with the protruding tongue 45 to clamp the workpiece.

It should be noted that in the present application, the receiving plate 43 is fixed, and the clamping unit 44 is relatively movable, so that when the material receiving arm 42 is moved to the position, the receiving plate 43 can be moved directly below the workpiece, and the clamping unit 44 can drive the pressing head 443 to swing around the second rotating shaft through the clamping cylinder 441, press the upper surface of the workpiece from top to bottom, and cooperate with the protruding tongue 45 to clamp the entire workpiece. Of course, in addition to the clamping manner, a common clamping cylinder can be used for clamping, and the workpiece cannot be clamped flatly like the clamping manner in the application.

In addition, this application still provides a transfer mechanism, and this mechanism can fine cooperation grabbing device carry the non-woven fabrics after the separation, and whole in-process can replace the manual work completely, has reduced the contact of folding membrane bagging-off in-process people and membrane, reduces the probability that membrane cloth is by secondary pollution, the safety and sanitation level of effectual improvement production efficiency and product, and stability is good, and the precision is high, compact structure, novelty, and the functioning speed is fast.
