An antistatic transmission belt for facial mask production

Abstract

The invention relates to an antistatic transmission belt for facial mask production applied in the field of facial mask processing. When conveying a non-woven fabric layer for facial mask processing, on the basis of realizing antistatic treatment, according to the stacking state of the non-woven fabric layer, a No. 2 electric stretching rod is used to descend and drive a pressure bar on the surface of the stacked non-woven fabric layer, so that the corners of the non-woven fabric layer are lifted up. Since the bottom non-woven fabric layer is adsorbed on the surface of the conveyor belt due to the pressure difference, when the facial mask has only one non-woven fabric layer, the movable plate is rotated to the gap between the bottom flat non-woven fabric layer and the lifted upper non-woven fabric layer, so as to achieve a clamping effect. When the facial mask is composed of a non-woven fabric layer and a mesh layer, after the No. 3 electric stretching rod is in a suitable stop position, the rotating motor is started to drive the pressing block to squeeze, so as to clamp the upper non-woven fabric layer and the mesh layer. Then the driving motor is started, and the No. 1 electric stretching rod and the No. 2 electric stretching rod are retracted at the same time, so as to drive the upper non-woven fabric layer constrained by the clamping to be peeled off.

Description

Technical Field

[0001] The invention relates to an antistatic transmission belt, in particular to an antistatic transmission belt for facial mask production applied in the field of facial mask processing. Background Art

[0002] There are many types of facial masks, and different types of facial masks have different functions and characteristics. The main types of facial masks used for daily care are: facial masks, gel masks, paste or gel masks, and tear-off masks. The facial mask patches are based on facial mask essence + facial mask cloth or paper. During processing, a conveyor belt is needed to transport the cut non-woven fabric to the mask folding machine. After folding, it is placed in a mask bag filled with essence and sealed.

[0003] The specification of Chinese patent CN201910950255.7 discloses a facial mask paper separation device using negative pressure adsorption. The facial mask paper separation device using negative pressure adsorption evacuates the air in the duct through an exhaust device to generate negative pressure at the adsorption hole, and cooperates with a nozzle, a first, a second, and a third pressure roller, thereby achieving the effects of high separation efficiency, no adhesion when separating the facial mask paper, and reliable quality of the facial mask paper after separation.

[0004] Existing mask conveying equipment uses negative pressure design to achieve the separation of mask paper. However, before the cut non-woven fabrics enter the folding machine, multiple cut non-woven fabrics are prone to stacking together, which will affect the quality of the mask during subsequent bagging. Therefore, attention should be paid to timely correction of the stacking phenomenon during transportation. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to improve the stacking phenomenon of non-woven fabrics during the process of conveying the cut non-woven fabrics to the folding machine, so as to ensure that the number of non-woven fabrics in each mask bag is controlled to one during subsequent bagging.

[0006] In order to solve the above problems, the present invention provides an anti-static transmission belt for facial mask production, comprising a support plate frame, a conveyor belt for conveying a non-woven fabric layer is installed on the surface of the support plate frame through a rotating roller, and the non-woven fabric layer is located at the center of the surface of the conveyor belt, the conveyor belt comprises a belt layer, an anti-static layer is installed on the surface of the belt layer, a through strip groove is provided inside the belt layer, and a breathable layer made of a transparent waterproof and breathable material is installed inside the strip groove, an air inlet pipe located below the upper conveyor belt is installed through the inside of the support plate frame, a detection support plate is arranged on the side of the conveyor belt away from the support plate frame, a flat plate extending to below the upper conveyor belt is installed on the surface of the detection support plate close to the support plate frame, and a plurality of equally spaced light source lamps are installed on the top of the flat plate, a bottom plate is installed on the top of the detection support plate through an L-shaped support rod, and a photosensor is installed on the bottom of the bottom plate;

A driving motor is installed on the top of the moving block. The output end of the driving motor is connected to a correction bar. A No. 1 electric extension rod and a No. 2 electric extension rod are installed at both ends of the bottom of the correction bar respectively. The power end of the No. 2 electric extension rod is connected to a pressure strip, and adjustment modules are installed at both ends of the pressure strip. The adjustment module includes a servo motor installed on the top of both ends of the pressure strip, the output end of the servo motor is connected to a movable plate located under the pressure strip, and the power end of the No. 1 electric extension rod is connected to a rubber block.

[0008] In the above-mentioned antistatic transmission belt for facial mask production, antistatic treatment is achieved by utilizing the cooperation of the air intake pipe and the antistatic layer. The non-woven fabric layer stacked on top of the bottom non-woven fabric layer is also peeled off through an electric slide rail, a light source lamp, a photosensor, an adjustment module, and a pressure strip.

[0009] As a further improvement of the present application, the projection of the No. 1 electric extension rod in the vertical direction is located on the side of the strip groove away from the detection support plate, and the projection of the pressure strip in the vertical direction is located on the side of the non-woven fabric layer close to the detection support plate.

[0010] As a further improvement of the present application, a ranging sensor is installed at the bottom of the movable plate, and a magnetic insertion strip is connected to the top of the movable plate. The output end of the servo motor is connected to a accommodating shaft rod. The interior of the accommodating shaft rod is provided with a constraint groove that is mutually engaged and slidable with the magnetic insertion strip, and an electromagnetic block is embedded in the top wall of the constraint groove.

[0011] As a further improvement of the present application, the projection of the light source lamp in the vertical direction is located on the side of the non-woven fabric layer away from the support plate frame, and the height value of the detection support plate is less than the installation height value of the air intake pipe.

[0012] As a further improvement of the present application, a transmission correction system is also included, which includes a processor installed on a support plate frame, and the processor is connected to a feedback module, an execution separation module, a refinement adjustment module and a maneuvering module. The feedback module is connected to the photosensitive sensor signal, and the stacking state of the non-woven fabric layer on the surface of the conveyor belt is detected by light transmittance. The maneuvering module is connected to the electric slide rail signal, and is used to move the moving block to the non-woven fabric layer where unqualified light transmittance is detected. The execution separation module is connected to the No. 1 electric stretching rod, the No. 2 electric stretching rod, the servo motor and the drive motor signal, and is used to assist the movable plate to separate the non-woven fabric layer stacked above the bottom non-woven fabric layer.

[0013] As a further improvement of the present application, the refinement adjustment module is connected to the distance measuring sensor and the electromagnetic block signal to adjust the distance value between the bottom of the movable plate and the top surface of the conveyor belt to the thickness value of a non-woven fabric layer.

[0016] As another improvement supplement of the present application, an image recognition and counting module is also connected to the processor, and the image recognition and counting module is connected to the image collector signal for counting the non-woven fabric layer and the mesh layer in the captured image. The execution separation module is also connected to the rotating motor and the No. 3 electric extension rod signal for assisting in separating the non-woven fabric layer with the mesh layer on the bottom surface and the upper non-woven fabric layer and the mesh layer.

[0017] To summarize, when conveying the non-woven fabric layer for facial mask processing, the present application utilizes the air inlet pipe and the strip groove to form a pressure difference on the surface of the conveyor belt, so that the non-woven fabric layer is constrained on the surface of the conveyor belt to reduce friction. Combined with the anti-static layer, anti-static treatment can be achieved during transportation. In addition, in view of the stacking state of the non-woven fabric layer, the No. 2 electric extension rod is lowered to drive the pressure bar on the surface of the stacked non-woven fabric layer, so that the corners of the non-woven fabric layer above the stacked state are lifted up. Since the bottom non-woven fabric layer is subjected to the pressure difference Adsorbed on the surface of the conveyor belt, when the facial mask has only one non-woven fabric layer, the movable plate rotates to the gap between the flat bottom non-woven fabric layer and the raised upper non-woven fabric layer, to achieve a clamping effect. When the facial mask is composed of a non-woven fabric layer and a mesh layer, after the No. 3 electric stretching rod is in a suitable stop position, the rotating motor is started to drive the pressing block to squeeze, and the upper non-woven fabric layer and the mesh layer are clamped. Then the driving motor is started, and the No. 1 electric stretching rod and the No. 2 electric stretching rod retract at the same time, driving the upper non-woven fabric layer that is clamped and constrained to be peeled off.

DETAILED DESCRIPTION

[0032] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1-4An antistatic transmission belt for facial mask production is shown, comprising a support plate frame 1, a conveyor belt 6 for conveying a non-woven fabric layer 001 is installed on the surface of the support plate frame 1 through a rotating roller, and the non-woven fabric layer 001 is located in the center of the surface of the conveyor belt 6, the conveyor belt 6 comprises a belt layer 61, an antistatic layer 62 is installed on the surface of the belt layer 61, a strip groove is provided inside the belt layer 61, and a breathable layer 63 made of a transparent waterproof and breathable material is installed inside the strip groove, an air inlet pipe 7 located below the upper conveyor belt 6 is installed inside the support plate frame 1, a detection support plate 2 is arranged on the side of the conveyor belt 6 facing away from the support plate frame 1, a flat plate extending to below the upper conveyor belt 6 is installed on the surface of the detection support plate 2 close to the support plate frame 1, and a plurality of equidistantly arranged light source lamps 8 are installed on the top of the flat plate, a bottom plate is installed on the top of the detection support plate 2 through an L-shaped support rod, and a photosensor is installed on the bottom of the bottom plate;

[0035] Figure 5 It is shown that an electric slide rail 3 is installed on the top of the support plate frame 1, and a moving block is installed for sliding inside the electric slide rail 3. A driving motor 4 is installed on the top of the moving block. The output end of the driving motor 4 is connected to a correction bar 5. The two ends of the bottom of the correction bar 5 are respectively installed with a No. 1 electric extension rod 51 and a No. 2 electric extension rod 52. The power end of the No. 2 electric extension rod 52 is connected to a pressure bar 53. The two ends of the pressure bar 53 are installed with adjustment modules, and the adjustment module includes a servo motor 54 installed on the top of the two ends of the pressure bar 53. The output end of the servo motor 54 is connected to a movable plate 55 located below the pressure bar 53. The power end of the No. 1 electric extension rod 51 is connected to a rubber block.

[0036] Specifically, when the facial mask is being transported, the non-woven fabric layer 001 is placed on the surface of the conveyor belt 6 equipped with the anti-static layer 62. Since the air inlet pipe 7 supplies airflow, the flow rate below the upper conveyor belt 6 will increase, thereby forming a pressure difference with the surface of the upper conveyor belt 6, so that the non-woven fabric layer 001 is adsorbed on the surface of the conveyor belt 6, which has a restraining effect, reduces the friction between the non-woven fabric layer 001 and the surface of the conveyor belt 6, and further enhances the anti-static effect during transportation. In addition, the installation range of the air inlet pipe 7 is smaller than the transportation length of the conveyor belt 6. When the conveyor belt 6 is close to the tail end (that is, close to the rotating roller), the adsorption effect caused by the pressure difference disappears, which facilitates the subsequent non-woven fabric layer 001 to separate from the surface of the conveyor belt 6.

[0037] In the above process, the design of the air-permeable layer 63 is used to prevent the non-woven fabric layer 001 from partially sinking into the strip-shaped groove due to the pressure difference, thereby ensuring the flatness of the surface of the non-woven fabric layer 001;

[0038] During the conveying process of the non-woven fabric layer 001, the light projected by the light source lamp 8 passes through the strip groove, the air permeable layer 63 and the non-woven fabric layer 001 and reaches the position of the photosensor. By detecting the light intensity, it can be determined whether it is in a stacking state (the light transmission ability is weakened in the stacking state, so the detection value of the photosensor is reduced), and the non-woven fabric layer 001 corresponding to the position of the light source lamp 8 is quickly obtained. Combined with the running speed of the conveyor belt 6, the electric slide rail 3 quickly drives the moving block to move to the position of the non-woven fabric layer 001 detected in the stacking state, and at the same time controls No. The electric extension rod 51 and the second electric extension rod 52 extend until the rubber block is squeezed on the surface of the conveyor belt 6, so that the conveyor belt 6 can drive the rubber block and the correction bar 5 to move synchronously when moving. After the second electric extension rod 52 is lowered, it drives the pressure bar 53 on the surface of the stacked non-woven fabric layer 001. During the pressing process of the pressure bar 53, the distance sensor at the bottom of the movable plate 55 detects the distance between the pressure bar 53 and the surface of the conveyor belt 6 until the distance between the pressure bar 53 and the conveyor belt 6 is equal to the thickness of the single-layer non-woven fabric layer 001. At this time, the second electric extension rod 52 stops extending further;

[0039] Figure 7 As shown, after the second electric extension rod 52 stops extending, due to the horizontal pressure of the pressure strip 53, the corners of the upper non-woven fabric layer 001 in the stacked state are lifted up (if the lifting cannot be formed due to the small number of stacked layers, since the distance between the movable plate 55 and the surface of the conveyor belt 6 is the thickness of a single non-woven fabric layer 001, the movable plate 55 will still push the non-woven fabric layer 001 above the bottom non-woven fabric layer 001 when it rotates, so that the upper non-woven fabric layer 001 forms wrinkles and is pushed away from the bottom non-woven fabric layer 001). The surface of the cloth layer 001 can be grabbed by a robot to complete the cleaning of the surface of the conveyor belt 6). The bottom non-woven fabric layer 001 is adsorbed on the surface of the conveyor belt 6 by the pressure difference. At this time, the servo motor 54 is started to drive the movable plate 55 to rotate to the gap between the bottom non-woven fabric layer 001 and the raised upper non-woven fabric layer 001, so as to achieve a clamping effect. After that, the driving motor 4 is started, and the No. 1 electric stretching rod 51 and the No. 2 electric stretching rod 52 are retracted at the same time, driving the upper non-woven fabric layer 001 constrained by the clamping to be peeled off (such as Figure 8 as shown).

[0040] The projection of the No. 1 electric extension rod 51 in the vertical direction is located on the side of the strip groove away from the detection support plate 2, and the projection of the pressure strip 53 in the vertical direction is located on the side of the non-woven fabric layer 001 close to the detection support plate 2.

[0041] Specifically, since the projection of the rubber block at the bottom of the No. 1 electric extension rod 51 is located outside the strip groove, when the No. 1 electric extension rod 51 is started to drive the rubber block to be squeezed on the surface of the conveyor belt 6, it can play a better friction contact role, so that when the electric slide rail 3 is stopped, it drives the correction horizontal bar 5 and the pressure strip 53 to move at the same speed as the conveyor belt 6. The design of the pressure strip 53 makes it convenient for it to be on one side of the non-woven fabric layer 001 after being pressed down, so as to form a raised foot.

[0042] Figure 6 As shown, a distance measuring sensor is installed at the bottom of the movable plate 55, and a magnetic insertion strip 551 is connected to the top of the movable plate 55, and an accommodating shaft rod 553 is connected to the output end of the servo motor 54. The interior of the accommodating shaft rod 553 is provided with a restraining groove that is mutually engaged and slidable with the magnetic insertion strip 551, and an electromagnetic block 552 is embedded in the top wall of the restraining groove.

[0043] Specifically, since the single-layer thickness of the non-woven fabric layer 001 is limited, the pressure strip 53 squeezes and drives the movable plate 55 to achieve limited position adjustment, so a more precise adjustment is required. When adjusting the distance between the movable plate 55 and the surface of the conveyor belt 6, the electromagnetic block 552 and the distance measuring sensor cooperate at the same time. By switching the adsorption and repulsion states of the electromagnetic block 552 and the magnetic insertion strip 551, the distance between the movable plate 55 and the surface of the conveyor belt 6 is adjusted until the requirements are met.

[0044] The projection of the light source lamp 8 in the vertical direction is located on the side of the non-woven fabric layer 001 away from the support plate frame 1 , and the height value of the detection support plate 2 is less than the installation height value of the air intake pipe 7 .

[0045] Specifically, the installation position of the light source lamp 8 allows the light it emits to pass smoothly through the non-woven fabric layer 001 . In addition, the installation height difference between the detection support plate 2 and the air intake pipe 7 ensures that the gas discharged from the air intake pipe 7 will not be intercepted by the detection support plate 2 .

[0046] It also includes a transmission correction system, which includes a processor installed on the support plate frame 1, and the processor is connected to a feedback module, an execution separation module, a refinement adjustment module and a mobilization module. The feedback module is connected to the light-sensitive sensor signal, and the stacking state of the non-woven fabric layer 001 on the surface of the conveyor belt 6 is detected by light transmittance. The mobilization module is connected to the electric slide rail 3 signal, and is used to move the moving block to the non-woven fabric layer 001 where unqualified light transmittance is detected. The execution separation module is connected to the No. 1 electric stretching rod 51, the No. 2 electric stretching rod 52, the servo motor 54 and the drive motor 4 signal, and is used to assist the movable plate 55 to separate the non-woven fabric layer 001 stacked above the bottom non-woven fabric layer 001.

[0047] The refinement adjustment module is connected to the distance sensor and the electromagnetic block 552 signal, and is used to adjust the distance value between the bottom of the movable plate 55 and the top surface of the conveyor belt 6 to the thickness value of a layer of non-woven fabric layer 001.

[0048] The second implementation method:

[0049] Fig. 9 The replacement structure of the adjustment module is shown to be a clamping adjustment unit, which includes a rotating motor 9 installed at the bottom of the tail end of the correction bar 5, the output end of the rotating motor 9 is connected to the No. 3 electric extension rod 10, the power end of the No. 3 electric extension rod 10 is connected to a pressure block 11 made of rubber material, and an image collector is installed on the surface of the pressure block 11.

[0050] The projection of the tail end of the correction horizontal strip 5 in the vertical direction is located on the side of the non-woven fabric layer 001 away from the supporting plate frame 1, and the mesh layer 002 is laid on the top of the non-woven fabric layer 001.

[0051] The processor is also connected to an image recognition and counting module, and the image recognition and counting module is connected to the image collector signal for counting the non-woven fabric layer 001 and the mesh layer 002 in the captured image. The execution separation module is also connected to the rotating motor 9 and the No. 3 electric extension rod 10 signal for assisting in separating the non-woven fabric layer 001 with the mesh layer 002 on the bottom surface and the upper non-woven fabric layer 001 and the mesh layer 002.

[0052] Unlike the first embodiment, the present embodiment improves the peeling process of the stacked non-woven fabric layer 001 with the mesh layer 002. In the first embodiment, the lifting operation will cause the mesh layer 002 on the surface of the bottom non-woven fabric layer 001 to also lift up, and the rotation of the movable plate 55 will also take away the mesh layer 002, resulting in poor peeling effect (such as Fig.10 as shown).

[0053] Specifically, in this embodiment, the third electric extension rod 10 and the pressing block 11 are on the same horizontal axis as the second electric extension rod 52;

[0054] When the non-woven fabric layer 001 with the gauze layer 002 is in a stacked state, the clamping and adjusting unit can be used to complete the peeling of the stacked part. After the stacked non-woven fabric layer 001 and the gauze layer 002 are lifted up (this process is the same as the first embodiment), the third electric extension rod 10 is started to drive the pressing block 11 to move to the surface of the conveyor belt 6. At this time, the image collector can capture the bottom non-woven fabric layer 001 in the adsorption state and the gauze layer 002 lifted up due to the action of the pressure strip 53 and the upper non-woven fabric layer 001 and the gauze layer 002. Since there are gaps between the lifted layers, it is convenient to check the number of layers. The third electric extension rod 10 retracts and moves upward, and the image recognition and counting module is used to count the number of layers passed by the pressing block 11 during the upward movement, so that the third electric extension rod 10 can be in a suitable stop position (this stop position is to make the pressing block 11 just pass over the bottom gauze layer 002 and squeeze the second to last non-woven fabric layer 001 during the subsequent circular motion, such as Fig.11 As shown), at this time, the rotating motor 9 is started to drive the pressing block 11 to squeeze and clamp the upper non-woven fabric layer 001 and the mesh layer 002, and then the driving motor 4 is started, and the No. 1 electric stretching rod 51 and the No. 2 electric stretching rod 52 are retracted at the same time, driving the upper non-woven fabric layer 001 to be peeled off, and the mesh layer 002 left on the surface of the conveyor belt 6 after losing the squeezing of the pressure strip 53 is restored to a flat state (as shown in FIG. Fig.12 as shown).

[0055] In summary, when conveying the non-woven fabric layer 001 for processing the facial mask, the present application uses the air inlet pipe 7 and the strip groove to form a pressure difference on the surface of the conveyor belt 6, so that the non-woven fabric layer 001 is constrained on the surface of the conveyor belt 6 to reduce friction. In combination with the anti-static layer 62, anti-static treatment can be achieved during transportation. In addition, for the stacking state of the non-woven fabric layer 001, the second electric extension rod 52 is used to descend to drive the pressure strip 53 horizontal bar on the surface of the stacked non-woven fabric layer 001, so that the corners of the non-woven fabric layer 001 above the stacking state are lifted up, and the bottom non-woven fabric layer 001 is adsorbed on the surface of the conveyor belt 6 due to the pressure difference;

[0056] When the mask has only one non-woven fabric layer 001, the servo motor 54 drives the movable plate 55 to rotate to the gap between the raised non-woven fabric layer 001 and the flat and restrained non-woven fabric layer 001, so as to achieve a clamping effect. When the mask is composed of the non-woven fabric layer 001 and the mesh layer 002, after the No. 3 electric extension rod 10 is in a suitable stop position, the rotating motor 9 is started to drive the pressing block 11 to squeeze, so as to clamp the upper non-woven fabric layer 001 and the mesh layer 002.

[0057] After that, the driving motor 4 is started, and the No. 1 electric extension rod 51 and the No. 2 electric extension rod 52 are retracted at the same time, driving the upper non-woven fabric layer 001 that is clamped and constrained to be peeled off.

[0058] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
