Description

Technical Field

[0001] This invention relates to the field of mask production technology, specifically to a mask finishing material feeding device for a mask machine. Background Technology

[0002] Masks are hygiene products that can block harmful gases, odors, droplets, viruses, and other substances from entering the lungs. Masks are generally made of gauze or other organic synthetic materials, and they have a certain filtering effect on the air entering the lungs. Currently, masks are produced and processed using fully automatic flat mask machines. After processing, the masks are collected and packaged by a feeding device. However, the existing feeding devices have certain drawbacks: they do not have a module to count the processed masks, and therefore cannot effectively control the production efficiency and progress of the device.

[0003] To address the aforementioned issues, utility model patent CN213568272U discloses a finished product unloading device for a fully automatic flat mask machine. This technical solution, by incorporating a counting mechanism, solves the problem that existing finished mask unloading methods cannot count products during production, thus hindering effective control of production efficiency and progress. However, the following problems remain unresolved: 1. The device lacks a structure for positioning the masks; the finished product unloading mechanism still results in skewed and scattered materials after they are placed on the conveyor belt. 2. The device cannot iron the finished masks; artificial wrinkles on the masks may affect subsequent packaging. 3. The device lacks a mechanism for correcting the ear loops; irregular movement of the ear loops significantly impacts transportation and packaging. Summary of the Invention

[0005] A pressure spring is fitted at one end of the pressure roller rod located inside the chain plate, and a through hole is opened at the other end of the pressure roller rod located outside the chain plate. The through hole is oriented in the front-to-back direction, and a return rod is slidably connected inside the through hole. The two ends of the return rod are slidably connected in T-slots. A return spring is fitted on a section of the return rod between the pressure roller rod and the front limit block. A pressure roller mounting frame is installed at the end of the pressure roller rod away from the middle of the chain conveyor belt. A hot pressure roller is installed on the pressure roller mounting frame. A guide plate is installed on the main frame located in the middle of the chain conveyor belt. The main conveyor belt is installed on the main frame directly below the chain conveyor belt. A hot pressure support plate is fixed on the main frame in the middle of the main frame surrounded by the main conveyor belt.

[0006] The collection assembly includes a support plate located on the left side of the main frame, a collection box above the support plate, the collection box having a hollow structure with openings on both the left and right sides, the left side being the lower half of the opening and the right side being the entire opening, gates on both the left and right sides of the collection box, a collection plate inside the collection box, an opening cylinder mounted on the upper side of the right side of the support plate, an opening block mounted on the piston rod of the opening cylinder, the opening block being hinged to the gates on both the front and rear sides by hinges, an ejection cylinder mounted on the left side of the opening block, an ejection block mounted on the top of the piston rod of the ejection cylinder, a pressing cylinder mounted on the top of the collection box, a pressing block mounted on the top of the piston rod of the pressing cylinder.

[0007] As a preferred embodiment of the present invention, a receiving plate is installed inside the opening on the right side of the collection box, and the receiving plate is in close contact with the left end of the main conveyor belt.

[0008] As a preferred embodiment of the present invention, the collecting plate has a square opening in the middle, the length and width of which are smaller than the length and width of the mask to be processed, and the collecting plate is arranged tilted to the left.

[0009] As a preferred embodiment of the present invention, the collecting plate is made of rubber, and ball bearings are provided at both the front and rear ends of the collecting plate.

[0010] As a preferred embodiment of the present invention, a guide groove is provided on the lower side of the guide plate. The guide groove of the horizontal part of the guide plate runs from left front to right rear, and the guide groove of the inclined part runs from left to right. The right end entrance of the guide groove of the inclined part is trumpet-shaped.

[0011] As a preferred embodiment of the present invention, the ear-pressing belt assembly includes an ear-pressing belt frame, a conveyor belt installed in the middle of the ear-pressing belt frame, and a transfer conveyor belt installed above the left end of the conveyor belt, which is closely attached to the outer side of the upper end of the conveyor belt; the right end of the transfer conveyor belt is horizontally attached to the upper right side of the main conveyor belt, and ironing plates arranged in a mirror image are installed on the ear-pressing belt frames on both sides of the middle section of the conveyor belt.

[0015] Second, the hot pressing component used in this invention can iron out the artificial folds on the mask to prevent the artificial folds from protruding and affecting the subsequent packaging. When the pressure roller enters the guide plate through the trumpet-shaped inlet, the guide groove of the inclined part of the guide plate presses down the pressure roller. Then the pressure roller cooperates with the guide groove of the horizontal part of the guide plate to hot press the mask, so that each mask can be hot pressed flat.

[0016] Third, the present invention has a receiving plate installed inside the opening on the right side of the collection box, and the receiving plate is close to the left end of the main conveyor belt, so that the mask can slide from the main conveyor belt onto the receiving plate and slide into the collection box through the receiving plate.

[0017] Fourth, the collection component used in this invention can sort and stack the masks falling from the conveyor belt, effectively preventing the finished product unloading mechanism from dropping the masks onto the conveyor belt and causing time-consuming sorting, thereby improving mask production efficiency and saving labor costs.

[0029] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0030] See Figure 1 and Figure 2 A mask-making machine finished product unloading device includes a main frame 1, an ear loop assembly 2 installed on the right side of the main frame 1, a heat-pressing assembly 3 installed on the main frame 1 and located to the left of the ear loop assembly 2, and a collecting assembly 5 installed to the left of the heat-pressing assembly 3. The ear loop assembly 2 used in this invention can straighten and iron the ear loops of the mask, effectively solving the problem of irregular movement of the ear loops during the subsequent packaging process. The heat-pressing assembly 3 can iron the artificial pleats on the mask to prevent the artificial pleats from protruding and affecting the subsequent packaging. The collecting assembly 5 used in this invention can sort and stack the masks falling from the conveyor belt, effectively preventing the finished product unloading mechanism from falling onto the conveyor belt in a crooked and scattered manner, which is time-consuming to sort, thus improving the mask production efficiency and saving labor costs.

[0031] See Figure 2 , Figure 7 and Figure 8 The ear loop assembly 2 includes an ear loop frame 21, a conveyor belt 22 installed in the middle of the ear loop frame 21, and a transfer conveyor belt 23 installed above the left end of the conveyor belt 22, closely attached to the outer side of the upper end of the conveyor belt 22. The right end of the transfer conveyor belt 23 is horizontally attached to the upper right side of the main conveyor belt 33. Ironing plates 24 arranged in a mirror image are installed on the ear loop frames 21 on both sides of the middle section of the conveyor belt 22. Gears 241 are installed on the left and right sides of the ironing plates 24, and the gears 241 mesh with racks 25 located in the middle of the conveyor belt 22. The other ends of the four racks 25 are respectively installed on two parallel double-headed cylinders 26. The ear loop assembly 2 of this invention can straighten and iron the ear loops of the mask, effectively solving the problem of ear loops in the subsequent packaging process. To address the issue of irregular movement during production, a combination of cylinders and gears / racks ensures smooth and reliable folding of the ironing plate 24, simplifying the overall transmission structure. Specifically, after the mask exits the production unit and enters the ear loop assembly 2, as the conveyor belt 22 reaches the corresponding position of the ironing plate 24, the double-headed cylinder 26 pushes the rack 25 forward and backward to both sides. The gear 241, meshing with the rack 25, rotates accordingly, causing the ironing plate 24 to fold inward. The ironing plate 24 bends and presses down the ear loops of the mask, simultaneously ironing and positioning them to fit snugly against the mask. After ironing, the double-headed cylinder 26 retracts, returning the ironing plate 24 to its original position. The mask with the ear loops ironed moves to the left along the conveyor belt 22 and enters the heat pressing assembly 3 with the assistance of the transfer conveyor belt 23.

[0032] See Figures 2 to 6The hot pressing assembly 3 includes a chain conveyor belt 31 mounted on the main frame 1 and located to the upper left of the pressure ear belt assembly 2. The chain conveyor belt 31 is composed of multiple chain plates 311. Limiting blocks 312 are provided at both ends of the chain plates 311. T-shaped grooves 313 running vertically are provided on opposite sides of the limiting blocks 312. Waist-shaped grooves 314 are opened on the chain plates 311. A pressure roller rod 35 is slidably installed in the middle of the waist-shaped groove 314. A downward pressure spring 351 is fitted at the end of the pressure roller rod 35 located inside the chain plate 311. A through hole 352 is opened at the end of the pressure roller rod 35 located outside the chain plate 311. The through hole 352 runs in the front-to-back direction. A return rod 36 is slidably connected inside the through hole 352. The two ends of the return rod 36 are slidably connected inside the T-slot 313. A return spring 361 is fitted on a section of the return rod 36 between the pressure roller rod 35 and the front limit block 312. A pressure roller mounting bracket 353 is installed at the end of the pressure roller rod 35 away from the middle of the chain conveyor belt 31. A hot pressure roller 354 is installed on the pressure roller mounting bracket 353. A guide plate 32 is installed on the main frame 1 and located in the middle of the chain conveyor belt 31. A main conveyor belt 33 is installed on the main frame 1 directly below the chain conveyor belt 31. A hot pressure support plate 34 is fixed on the main frame 1 surrounded by the main conveyor belt 33.

[0033] The hot-pressing component 3 used in this invention can iron out the artificial pleats on the mask, preventing the artificial pleats from protruding and affecting subsequent packaging. It should be noted that the chain conveyor belt 31 and the main conveyor belt 33 have the same linear speed, with the chain conveyor belt 31 rotating clockwise and the main conveyor belt 33 rotating counterclockwise. Specifically, when the mask enters the hot-pressing component 3, it moves to the left along with the main conveyor belt 33. When it moves below the guide plate 32, the end of the pressure roller rod 35 facing the inside of the chain conveyor belt 31 rotates with the chain conveyor belt 31 and enters the guide groove 321 through the trumpet-shaped opening on the right side of the guide plate 32. First, it presses down in conjunction with the guide groove 321 of the inclined part of the guide plate 32, compressing the pressure spring 351. The return rod 36 moves with the limit block 3. The T-groove 313 on 12 slides outward from the chain conveyor belt 31. After the hot roller 354 on the pressure roller mounting bracket 353 contacts the mask below, it enters the horizontal part of the guide plate 32. The pressure roller rod 35 moves from back to front with the rotation of the chain conveyor belt 31 and the guide groove 321 of the horizontal part of the guide plate 32, driving the lower hot roller 354 to roll the mask from back to front. Because the main conveyor belt 33 is easily deformed, a hot pressing support plate 34 is set at the hot pressing position to prevent the main conveyor belt 33 from deforming and affecting the hot pressing effect. When the pressure roller rod 35 disengages from the guide plate 32, the lower pressure spring 351 springs up and drives the return rod 36 to slide inward from the chain conveyor belt 31. At the same time, the return spring 361 pushes the pressure roller rod 35 back to its original position. The hot pressing is completed and the mask enters the collection assembly 5.

[0034] See Figure 4The guide plate 32 has a guide groove 321 on its lower side. The guide groove 321 of the horizontal part of the guide plate 32 runs from left front to right rear, and the guide groove 321 of the inclined part runs from left to right. The right end entrance of the guide groove 321 of the inclined part is funnel-shaped. The funnel-shaped opening makes it easier for the pressure roller rod 35 to enter the guide groove 321. Specifically, when the pressure roller rod 35 enters the guide plate 32 through the funnel-shaped entrance, the guide groove 321 of the inclined part of the guide plate 32 presses down the pressure roller rod 35. Then the pressure roller rod 35 cooperates with the guide groove 321 of the horizontal part of the guide plate 32 to heat press the mask.

[0035] See Figure 9 The collecting assembly 5 includes a support plate 51 located on the left side of the main frame 1. A collecting box 52 is disposed above the support plate 51. The collecting box 52 has a hollow structure with openings on both the left and right sides. The left side has an opening in the lower half, and the right side has an opening on the entire surface. Gate plates 53 are disposed on both the left and right sides of the collecting box 52. A collecting plate 521 is disposed inside the collecting box 52. An opening cylinder 55 is installed on the upper side of the right side of the support plate 51. An opening block 551 is installed on the piston rod of the opening cylinder 55. The opening block 551 is hinged to the gate plate 53 on both the front and rear sides. A push-out cylinder 56 is installed on the left side of the opening block 551. A push-out block 561 is installed at the top of the piston rod of the push-out cylinder 56. A pressing cylinder 57 is installed on the top of the collecting box 52. A pressing block 571 is installed at the top of the piston rod of the pressing cylinder 57. The collecting assembly 5 of this invention can sort and stack the masks falling from the conveyor belt, effectively preventing the finished product unloading mechanism from skewing and scattering the masks after they fall onto the conveyor belt. This process addresses the time-consuming issue of mask production, improving efficiency and saving labor costs. Specifically, after the masks are heat-pressed, they continue to move to the left along the main conveyor belt 33. When the masks reach the end of the main conveyor belt 33, they slide along the receiving plate 54 onto the collection plate 521 in the collection box 52. Because the length and width of the square opening on the collection plate 521 are smaller than the length and width of the masks to be processed, the masks remain on the collection plate 521. As the number of masks accumulates to a certain level, the pressing cylinder 57 extends, driving the pressing block 571 to press the stacked masks down from the opening on the collection plate 521 and onto the support plate 51. After the masks fall, the opening cylinder 55 extends, driving the opening block 551 to lift the right gate plate 53 via the hinge. The right gate plate 53, through the connecting rod 531, drives the left connecting rod 531 to rise as well. Then, the pushing cylinder 56 extends, driving the pushing block 561 to extend to the left, pushing the stacked masks out of the collection box 52, allowing the stacked masks to enter the subsequent packaging device.

[0036] See Figure 9 A receiving plate 54 is installed inside the opening on the right side of the collection box 52, and the receiving plate 54 is close to the left end of the main conveyor belt 33, so that the mask can slide from the main conveyor belt 33 onto the receiving plate 54 and slide into the collection box 52 through the receiving plate 54.

[0037] See Figure 9 The collecting plate 521 is made of rubber and has a square opening in the middle. The length and width of the square opening are smaller than the length and width of the mask to be processed. The collecting plate 521 is tilted to the left and has ball bearings at both the front and rear ends. The ball bearings allow the mask to slide along the tilting direction of the collecting plate 521 to the left side wall of the collecting box 52 for positioning. Specifically, because the length and width of the square opening on the collecting plate 521 are smaller than the length and width of the mask to be processed, the mask will remain on the collecting plate 521. When the number of masks accumulates to a certain amount, the pressing cylinder 57 extends and drives the pressing block 571 to press the stack of masks down from the opening on the collecting plate 521.

[0038] See Figure 9 The gates 53 located on the left and right sides of the collection box 52 are connected by connecting rods 531 that control their synchronous up and down movement, so as to facilitate the synchronous opening and closing of the gates 53. Specifically, when the mask falls from the collection plate 521, the gate opening cylinder 55 extends and drives the gate opening block 551 to lift the right gate 53 through the hinge. The right gate 53 drives the left connecting rod 531 to rise together through the connecting rod 531.

[0039] The present invention describes the following feeding steps for a mask-making machine's finished mask feeding device:

[0040] In the first step, after the mask comes out of the production unit, it enters the ear loop assembly 2. As the conveyor belt 22 moves to the corresponding position of the ironing plate 24, the double-headed cylinder 26 pushes the rack 25 forward and backward to both sides. The gear 241 meshing with the rack 25 rotates accordingly, causing the ironing plate 24 to fold inward. The ironing plate 24 bends and presses down the ear loops of the mask, while ironing and positioning the ear loops to fit the mask. After ironing, the double-headed cylinder 26 retracts, causing the ironing plate 24 to return to its original position. The mask with the ear loops ironed moves to the left with the conveyor belt 22 and enters the heat pressing assembly 3 with the help of the transfer conveyor belt 23.

[0041] In the second step, when the mask enters the hot pressing assembly 3, it moves to the left along the main conveyor belt 33. When it moves below the guide plate 32, the end of the pressure roller rod 35 facing the inner side of the chain conveyor belt 31 rotates with the chain conveyor belt 31 and enters the guide groove 321 through the trumpet-shaped opening on the right side of the guide plate 32. First, it presses down in the guide groove 321 of the inclined part of the guide plate 32, and the pressure spring 351 is compressed. The return rod 36 slides outward along the T-slot 313 on the limit block 312. After the hot pressing roller 354 on the pressure roller mounting bracket 353 contacts the mask below, it enters the guide groove 321. In the horizontal section of plate 32, the pressure roller 35 moves from back to front in coordination with the guide groove 321 of the horizontal section of guide plate 32 as the chain conveyor belt 31 rotates, driving the lower hot pressure roller 354 to roll the mask from back to front. Because the main conveyor belt 33 is easily deformed, a hot pressure support plate 34 is set at the hot pressure position to prevent the main conveyor belt 33 from deforming and affecting the hot pressure effect. When the pressure roller 35 disengages from the guide plate 32, the lower pressure spring 351 springs up and drives the return rod 36 to slide inward to the chain conveyor belt 31. At the same time, the return spring 361 pushes the pressure roller 35 back to its original position. The hot pressure is completed and the mask enters the collection assembly 5.

[0042] Third, after the masks are heat-pressed, they continue to move to the left along the main conveyor belt 33. When the masks reach the end of the main conveyor belt 33, they slide along the receiving plate 54 onto the collection plate 521 in the collection box 52. Because the length and width of the square opening on the collection plate 521 are smaller than the length and width of the masks to be processed, the masks will stay on the collection plate 521. As the number of masks accumulates to a certain amount, the pressing cylinder 57 extends and drives the pressing block 571 to press the stacked masks down from the opening on the collection plate 521 and onto the support plate 51. After the masks fall, the opening cylinder 55 extends and drives the opening block 551 to lift the right gate plate 53 through the hinge. The right gate plate 53 drives the left connecting rod 531 to rise together through the connecting rod 531. Then the pushing cylinder 56 extends and drives the pushing block 561 to extend to the left, pushing the stacked masks out of the collection box 52, so that the stacked masks enter the subsequent packaging device.

[0043] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered within the protection scope of the present invention.
