Description

Technical Field

[0001] The utility model relates to the technical field of production line equipment for fully-automatically producing cup-shaped masks, in particular to a slitting device and production line equipment for producing masks. Background Art

[0002] Cup-shaped masks are designed for people's health. They are used to filter out some visible or invisible substances that are harmful to the human body, so as not to bring unnecessary health effects to the human body. Compared with flat masks, cup-shaped masks have the following advantages: 1. The unique cup-shaped design makes the mask more airtight to the face, and dust and viruses cannot easily leak in; 2. The ergonomic nose design and built-in soft foam nose pad increase the comfort of wearing.

[0003] In the mask manufacturing industry, manufacturers generally use mask forming machines to prepare mask substrates, and mask substrates generally use non-woven fabrics; the following takes the preparation of cup-shaped mask substrates as an example to illustrate the processing process of mask forming machines: mask forming machines generally use thermoforming to prepare cup-shaped mask substrates, that is, the lower mold of the mask forming machine is a concave mold with a cup-shaped pit, and the upper mold is a convex mold with a cup-shaped protrusion. The non-woven fabric to be formed is placed in the forming area between the upper mold and the lower mold and the upper mold and the lower mold are clamped by a clamping mechanism. After clamping, the upper and lower molds are heated at the same time and finally the non-woven fabric is formed into a cup shape.

[0004] After the inner cup substrate is formed, the outer cup fabric must be processed. In order to adapt to the production of masks of different sizes, the outer cup fabric is usually relatively wide. The traditional cutting method is to cut a suitable size of outer cup fabric from the middle, which easily causes waste of fabric on both sides and increases production costs.

[0005] In addition, after the inner cup and the outer cup of the mask are welded and shaped as a whole, other operations need to be performed on the mask, such as welding the breathing valve, attaching the aluminum strip of the nose bridge, welding the ear straps or attaching the sponge strip, etc. Among them, attaching the sponge strip is particularly difficult, because the mask has been shaped and has gone through the above-mentioned other steps. Therefore, when attaching the sponge strip, it is easy to affect other accessories and it is easy to cause the sponge strip to be attached inaccurately and firmly. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. 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.

[0037] See also Figures 1 to 10 In an embodiment of the utility model, a front section of a production line equipment 70 includes the above-mentioned slitting device 10, and also includes a raw material support 71, an inner cup hot pressing device 72, an outer cup cutting device 73, an integral welding device 74 and an integral chopping device 75. The raw material support 71 provides inner cup raw materials and outer cup raw materials respectively, wherein the inner cup raw materials are transported to the inner cup hot pressing device 72 for hot pressing molding to form an inner cup molded part; the outer cup raw materials are transported to the slitting device 10 for slitting to form two pieces of special-shaped fabrics 91; the outer cup cutting device 73 is used to cut and fold the special-shaped fabric 91 and place it on the inner cup molded part; the integral welding device 74 welds the stacked special-shaped fabrics 91 to the inner cup molded part to form an integral molded part; the neat chopping device trims the integral molded part to form a semi-finished mask.

[0038] A rear section of a production line equipment 70 includes the above-mentioned cotton strip attaching device 30, and also includes a feeding module 81, a punching mechanism 82, a welding valve mechanism 83, a printing mechanism 84, a nose bridge strip attaching mechanism 85 and a welding belt mechanism 86. The feeding module 81 is used to transport the formed mask semi-finished product from the previous station into the production line equipment 70, the punching mechanism 82 is used to stamp the mask semi-finished product to form a hole for installing a breathing valve; the welding valve mechanism 83 welds the pre-assembled complete breathing valve into the hole, the printing mechanism 84 prints preset graphics on the mask semi-finished product, the nose bridge strip attaching mechanism 85 is used to attach the nose bridge aluminum strip to the mask semi-finished product, the welding belt mechanism 86 is used to weld the ear straps of the mask semi-finished product, and the cotton strip attaching device 30 is used to attach the sponge strip 93 to the mask semi-finished product.

[0039] Specifically, in order to realize the automatic production of the cup-shaped mask 90, a production line can be used, and corresponding workstations and corresponding devices or mechanisms are set on both sides of the production line to perform corresponding operations, so that the inner cup raw material and the outer cup raw material are input at one end, and the finished product of the cup-shaped mask 90 can be directly output at the other end. Thereby improving production efficiency, saving production costs, and enhancing production competitiveness. The devices or mechanisms not described in detail in the present utility model can be set using existing products in the prior art.

[0040] First, in the front section of the production line equipment 70, the outer cup fabric and the inner cup fabric of the cup-shaped mask 90 are mainly produced, wherein the inner cup fabric is subjected to the inner cup molding process to form an inner cup molded part. The inner cup hot pressing device 72 can be carried out using existing products in the prior art, or refer to the technical solutions previously applied for by the applicant. After the outer cup fabric is cut by the slitting device 10 to form a special-shaped fabric 91, it can be placed on the inner cup molded part after being cut and folded by the outer cup cutting device 73, first pre-welded, then welded as a whole, and finally trimmed to form a semi-finished product of the mask. The welding operation preferably adopts ultrasonic welding in the prior art.

[0041] Secondly, in the latter part of the production line equipment 70, the accessories of the semi-finished mask are mainly installed. For example, for a mask that needs to be installed with a breathing valve, a punching process can be performed first, and then the breathing valve can be ultrasonically welded. For another example, for a mask that needs to be printed with a graphic logo, a printing mechanism 84 can be used to perform a preset graphic printing operation on it. In order to make the cup-shaped mask 90 fit better, the nose bridge strip mechanism 85 can also be used to attach the aluminum strip to the bridge of the nose. Of course, it is also necessary to perform a welding operation on the ear straps or headbands so that it can be worn on the ears or head. Finally, in order to improve its fit and enhance its comfort, a nose sponge strip 93 can also be attached to the mask.

[0042] In another embodiment, if Figures 1 to 3 As shown, preferably, a slitting device 10 for producing masks comprises a slitting bracket 11, a slitting cloth guide assembly 12, a slitting tool 20 and a slitting power assembly 13 installed on a production line equipment 70, wherein the slitting bracket 11 is fixedly connected to the production line equipment 70, the slitting cloth guide assembly 12 is rotatably connected to the slitting bracket 11, the slitting power assembly 13 is fixedly connected to the slitting bracket 11, and the slitting power assembly 13 is transmission-connected to the slitting cloth guide assembly 12, so that the slitting cloth guide assembly 12 drives and guides the outer cup material after operation, so that the outer cup material passes through the slitting tool 20, thereby being slitting into two pieces of cloth; the slitting tool 20 is provided with an ultrasonic assembly 24 and a special-shaped cutter head assembly 25, the ultrasonic assembly 24 is fixedly connected to the slitting bracket 11, the special-shaped cutter head assembly 25 is movably connected to the slitting bracket 11, and is transmission-connected to the slitting power assembly 13, the ultrasonic assembly 24 and the special-shaped cutter head assembly 25 cooperate with each other, thereby cutting the outer cup material into two pieces of special-shaped cloth 91.

[0043] Specifically, in order to meet the production of masks of different sizes, the width of the outer cup raw material is usually produced relatively wide. However, the purchased outer cup raw material is prone to waste in the process of producing some non-large-sized masks. If the outer cup raw material is cut in half from the middle and produced as two outer cup fabrics, it will result in a size that is too small and can only be used for the production of small masks, but not suitable for the production of commonly used mask sizes. Therefore, after research and development, a slitting device 10 is specially set up, which can cut a piece of outer cup raw material from the middle position into two special-shaped fabrics 91, and cut the adjacent side of the two special-shaped fabrics 91 into a wavy edge line 92, so that the protruding part can form the fabric of the outer cup edge, thereby avoiding the waste of outer cup raw materials and saving production costs. In addition, the slitting power assembly 13 can use a combination of existing motors and gears in the prior art to generate corresponding rotational power.

[0044] Among them, the main principle is that the cup-shaped mask 90 is usually arc-shaped, so when the outer cup material is cut, the arc edge is directly cut out, thereby reducing the size of the part cut off during the overall trimming later, so that the outer cup material can be cut into two special-shaped fabrics 91, thereby avoiding the problem of insufficient size of the outer cup material when producing commonly used mask sizes, thereby saving the outer cup material.

[0045] like Figure 3As shown, preferably, the special-shaped cutter head assembly 25 is provided with a cutter shaft 26, a cutter seat 27 and an annular blade 28, the cutter shaft 26 is rotatably connected to the slitting bracket 11, and is transmission-connected to the slitting power assembly 13; the cutter seat 27 is sleeved on the cutter shaft 26 and is fixedly connected; the annular blade 28 is fixedly connected to the outer wall of the cutter seat 27, and the plane formed by the annular blade 28 forms a certain angle with the end face of the cutter seat 27, so that the annular blade 28 forms an oblique cutting edge, thereby cutting the adjacent side of the two special-shaped cloths 91 into a wavy edge line 92.

[0046] Specifically, the central axis of the annular blade 28 forms a certain angle with the central axis of the blade holder 27, that is, the annular blade 28 is fixed to the blade holder 27 at a certain angle. With such a design, during the rotation and cutting process of the blade shaft 26, the annular blade 28 can guide the ultrasonic component 24 to perform corresponding S-shaped cutting on the outer cup fabric, so that it is cut into a wavy edge line 92, that is, the size of the raised part is increased, so that masks of common sizes can be produced.

[0047] like Figure 2 As shown, preferably, the slitting tool 20 is also provided with a first cylinder 21, a first slide rail 22 and a first slider 23, the first cylinder 21 and the first slide rail 22 are respectively fixed to the slitting bracket 11, the knife shaft 26 is rotatably connected to the first slider 23, and the first slider 23 is fixed to the piston rod of the first cylinder 21, so that the first piston can control the knife shaft 26 to move up and down a certain distance.

[0048] Specifically, the first piston controls the knife shaft 26 to move up and down, and can also drive the knife seat 27 and the special-shaped blade to move up and down synchronously. In addition, the ultrasonic component 24 can be installed using an ultrasonic cutting device in the prior art. Ultrasonic cutting is an advanced cutting technology that uses ultrasonic mechanical vibrations to generate high-frequency energy, which is applied to the cloth to produce a thermal effect, thereby achieving non-contact cutting. The transducer is usually made of ceramic material, and its structure is very special, which can convert mechanical vibrations into ultrasonic waves. During the cutting process, ultrasonic waves can generate mechanical energy, which is applied to the cloth, causing it to produce an undulating motion, forming a cutting effect. At this time, the tool can only play a guiding role without actual cutting.

[0049] In another embodiment, if Figures 4 to 8As shown, preferably, a cotton strip sticking device 30 for producing masks comprises a dividing turntable 31 and a strip sticking mechanism 40 installed on the production line equipment 70, wherein a plurality of turntable carriers 32 are fixedly connected to the dividing turntable 31, and the turntable carrier 32 is driven to rotate at a certain angle, thereby moving the turntable carrier 32 between a plurality of workstations; the turntable carrier 32 is provided with a limiting ring 33, and the limiting ring 33 is used to place a cup-shaped mask 90, and to support and limit the cup-shaped mask 90, and the strip sticking mechanism 40 is used to attach a sponge strip 93 to the cup-shaped mask 90 on the limiting ring 33.

[0050] Specifically, with the support of the limiting ring 33, the strip sticking mechanism 40 can accurately and firmly stick the sponge strip 93 to the cup-shaped mask 90 on the turntable carrier 32. The limiting ring 33 is provided with a supporting edge 34, and the supporting edge 34 is attached to the nose wing part of the cup-shaped mask 90 and supports it, so that the strip sticking mechanism 40 is more accurate and firm when sticking the sponge strip 93. The supporting edge 34 is arranged at the lower part of the nose wing part corresponding to the cup-shaped mask 90 to which the sponge strip 93 is attached. It can be understood that the middle part of the turntable carrier 32 is preferably set to correspond to the opening of the cup-shaped mask 90, so that the cup-shaped mask 90 can be placed inside the opening of the turntable carrier 32 after being turned over, and the limiting ring 33 on its edge can also support the cup-shaped mask 90, that is, stabilize the cup-shaped mask 90, so that it will not be displaced and deformed during the process of sticking the sponge strip 93, and can also protect other accessories of the cup-shaped mask 90. ​​For example, the breathing valve can pass through the opening and will not be crushed. The ear straps or headbands can be spread out on the outer ring of the limiting ring 33 to avoid being pulled.

[0051] like Figure 6 As shown, preferably, the turntable carrier 32 is also provided with a clamping fork 35, a clamping spring 36, an ejector rod 37 and an ejector cylinder 38, the clamping fork 35 is rotatably connected to the turntable carrier 32, one end of the clamping spring 36 is fixed to the clamping fork 35, and the other end thereof is fixed to the turntable carrier 32, and its elastic force enables the fork head of the clamping fork 35 to clamp the edge portion of the cup-shaped mask 90; the ejector cylinder 38 is installed on the frame of the production line equipment 70, one end of the ejector rod 37 is fixed to the piston rod of the ejector cylinder 38, and the other end thereof abuts against the clamping fork 35, so that the ejector cylinder 38 drives the ejector rod 37 to move, so that the ejector rod 37 can push the clamping fork 35 to rotate a certain angle, thereby causing the fork head of the clamping fork 35 to loosen the edge portion of the cup-shaped mask 90, so that the cup-shaped mask 90 can be removed from the turntable carrier 32.

[0052] Specifically, in order to further stabilize the cup-shaped mask 90, a pressing fork 35 can be provided, and its plug can be used to press the edge of the mask so that the mask is firmly and stably placed on the turntable carrier 32. The ejector rod 37 abuts against the other end opposite to the fork of the pressing fork 35, so that after the pressing fork 35 is rotated by a certain angle, the fork of the pressing fork 35 can be tilted, thereby loosening the cup-shaped mask 90.

[0053] like Figure 7 and Figure 8 As shown, preferably, the strip sticking mechanism 40 is provided with a strip sticking bracket 41, a sponge strip feeding rack 42, a separation table 43, a sponge strip clamp 44 and a sponge strip pressing block 47, the strip sticking bracket 41 is fixedly connected to the production line equipment 70, the sponge strip feeding rack 42 is rotatably connected to the strip sticking bracket 41, and is used to supply raw materials of the sponge strip 93; the separation table 43 is fixedly connected to the strip sticking bracket 41, and is used to separate the sponge strip 93 from the raw material release paper; the sponge strip clamp 44 is movably connected to the strip sticking bracket 41, and is used to clamp the sponge strip 93 on the separation table 43, and move it to the nose wing part of the cup-type mask 90 of the turntable carrier 32 for attachment; the sponge strip pressing block 47 is movably connected to the strip sticking bracket 41, and is used to press the attached sponge strip 93.

[0054] Specifically, in order to better clamp the sponge strip 93, it is preferred to provide a relatively wide clamping plate 46. When the sponge strip 93 leaves the factory, it is attached to the release paper, so a separation table 43 can be provided. When the release paper slides on the separation table 43, the sponge strip 93 can be separated to a certain extent, and the attachment between the sponge strip 93 and the release paper is released, so that the sponge strip 93 can be clamped away from the release paper.

[0055] Secondly, the sponge bar clamp 44 is provided with a corresponding clamping cylinder 45 and two clamping plates 46, and the two clamping plates 46 are respectively fixed to the two driving shafts of the clamping cylinder 45, so that the clamping cylinder 45 can drive the two clamping plates 46 to clamp.
