Description

Technical Field

[0001] This invention relates to the field of nitrile glove processing technology, and more specifically to a drying and blowing apparatus for nitrile glove processing. Background Technology

[0002] Nitrile gloves are gloves made or coated with a protective coating to prevent oil damage. They are mainly used in factories, oil fields, and repair shops. Nitrile gloves do not contain latex protein, so they will not cause allergic reactions. They also have antistatic, aging-resistant, and oil-resistant properties. The gloves are designed according to the shape of the human hand, providing excellent sensitivity, good tensile strength and puncture resistance, high tensile strength, and excellent abrasion resistance.

[0003] Application No. 2021104529476 discloses a rapid drying device for nitrile glove production. This device first places the glove onto a hand mold, then places the glove-covered hand mold into the drying device. This method increases the contact area between the glove and the hot air blown from the drying device, preventing the glove from wrinkling and ensuring some areas remain dry, thus increasing the drying rate. However, in actual production, nitrile glove processing is a streamlined process where the hand mold is not removed for further processing; the drying process is completed on the assembly line. Therefore, this device is not suitable for assembly line operations. Furthermore, after the existing gloves are dipped and molded, adhesive residue remains on the surface; directly applying the drying air would result in poor drying performance. Summary of the Invention

[0004] The purpose of this invention is to provide a drying and blowing device for nitrile glove processing, solving the following technical problems: In actual production, nitrile glove processing is an assembly line operation, and the hand mold is not removed for further processing. Instead, the drying process is completed on the assembly line. Therefore, this device is not suitable for assembly line operations. Secondly, after the existing gloves are dipped and molded, there is still glue residue on their surface. Directly drying and blowing them will result in poor drying and blowing effects.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A drying and blowing device for nitrile glove processing includes a housing. Two sprockets are rotatably connected inside the housing, and a chain is sleeved around the two sprockets. Multiple hand mold mounting mechanisms are installed on the chain. A drying and blowing box is fixedly installed at the center of one side of the housing. An arc-shaped protrusion is provided inside the drying and blowing box and on the chain. Two cylinders are symmetrically arranged inside the drying and blowing box. A mold base is fixedly installed at the piston rod end of cylinder one. A rotating arc plate is slidably connected to the mold base. A hand mold is installed on the rotating arc plate, and removable absorbent cotton is adhered inside the hand mold. A half gear is fixedly installed on one side of the rotating arc plate, and two half gears are inserted and fixed together. A cylinder is also fixedly installed inside the drying and blowing box. A movable plate is fixedly installed on the piston rod of cylinder two and slidably connected to the drying and blowing box. A reciprocating rack is provided on the movable plate, and the rack meshes with the half gear.

[0007] As a further embodiment of the present invention: a rotary motor is fixedly mounted on the movable plate, an eccentric wheel is fixedly mounted on the output shaft of the rotary motor, the eccentric wheel is perpendicular to the rack three, and the end of the rack three away from the eccentric wheel is fixedly connected to the movable plate through a return spring.

[0008] As a further aspect of the present invention: the interior of the drying box is provided with an arc-shaped guide plate in an S-shape.

[0009] As a further embodiment of the present invention: the hand mold mounting mechanism includes a rotating shaft rotatably mounted on a chain, a gear fixedly mounted on the rotating shaft, the gear meshing with a rack horizontally arranged inside the drying chamber, and an mounting sleeve fixedly mounted at the end of the rotating shaft, the mounting sleeve being fixedly connected to the POM hand mold.

[0010] As a further aspect of the present invention: an electromagnet is provided inside the mounting sleeve, and a magnet is provided at the end of the POM hand mold.

[0011] As a further aspect of the present invention: a folding roller is provided on one side of the outer shell, and a toothed rack is horizontally provided above the folding roller.

[0012] As a further aspect of the present invention: a guide plate is provided on one side of the rack, and an arc-shaped edge is provided at one end of the guide plate.

[0013] The beneficial effects of this invention are:

[0014] When the hand mold is positioned between the upper and lower hand molds, cylinder one is activated, moving the two mold seats inward and consequently the rotating arc plate inward. The upper and lower hand molds cover the hand mold, allowing the absorbent cotton to contact the glove surface and absorb excess liquid. Simultaneously, the two half-gears are engaged to form a single unit for synchronized rotation. Then, cylinder two is activated, pushing the moving plate to engage the rack three with the half-gears. The rotary motor is then activated, rotating the eccentric wheel. Under the action of the return spring, the eccentric wheel pushes the rack three in reciprocating motion, which in turn rotates the half-gears, causing the rotating arc plate and hand molds to rotate. Since the hand mold mounting mechanism is rotating, it can accelerate the absorption of liquid from the glove surface, facilitating subsequent drying and blowing.

[0015] Then, the hand mold is released, and it continues to move. Cold air is blown into the drying chamber by a blower. The cooling air is guided by an S-shaped arc-shaped baffle to ensure continuous contact between the cold air and the nitrile gloves, resulting in better drying. At the same time, the rack and pinion mechanism allows the nitrile gloves to rotate continuously during the drying process, ensuring more comprehensive contact and further improving the drying effect. The two steps work together to accelerate the drying efficiency and achieve better results, making it suitable for assembly line operations. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-4 As shown, the present invention is a drying and blowing device for processing nitrile gloves, including a housing 1. Two sprockets 3 are rotatably connected inside the housing 1, one of which is driven by a motor. Chains 2 are sleeved on the outside of the two sprockets 3. Multiple hand mold mounting mechanisms 7 are installed on the chains 2. A drying and blowing box 4 is fixedly installed at the center of one side of the housing 1. A blower is provided on the drying and blowing box 4. The interior of the drying and blowing box 4 is provided with an S-shaped arc-shaped guide plate 42. Cold air is blown into the drying and blowing box 4 by the blower. The air is guided by the arc-shaped guide plate 42 to ensure that the cold air is in continuous contact with the nitrile gloves, resulting in a better drying and blowing effect. At the same time, during the drying and blowing process, the rack 41 makes it easier for the nitrile gloves to rotate continuously, making the contact more comprehensive, which further improves the drying and blowing effect.

[0024] The drying oven 4 has an arc-shaped protrusion 21 located inside and on the chain 2. This protrusion 21 allows the hand mold to be horizontal after passing through it, facilitating subsequent mold processing. Two cylinders 43 are symmetrically arranged inside the drying oven 4. A mold base 44 is fixedly mounted on the piston rod end of each cylinder 43. A rotating arc plate 45 is slidably connected to the mold base 44. The rotating arc plate 45 has an arc-shaped groove, with the grooves on the upper and lower mold bases 44 corresponding one-to-one, allowing the rotating arc plates 45 to rotate relative to each other. A slider is slidably connected within the arc groove, and the rotating arc plate 45 is fixedly mounted on the slider. A hand mold 46 is mounted on the rotating arc plate 45, and a detachable suction cup is adhered inside the hand mold 46. A water-absorbing cotton 414 is provided for easy replacement. A half-gear 47 is fixedly installed on one side of the rotating arc plate 45. The upper and lower half-gears 47 are inserted and fixed together. The bottom of the upper half-gear 47 has an insertion hole, and the top of the lower half-gear 47 has an insertion block. A cylinder 2 48 is also fixedly installed inside the drying box 4. A moving plate 410 is fixedly installed on the piston rod of the cylinder 2 48. The moving plate 410 is slidably connected to the drying box 4. A reciprocating rack 3 412 is provided on the moving plate 410. The rack 3 412 meshes with the half-gear 47. A rotary motor 49 is fixedly installed on the moving plate 410. An eccentric wheel 411 is fixedly installed on the output shaft of the rotary motor 49. The eccentric wheel 411 is perpendicular to the rack 3 412. The end of the rack 3 412 away from the eccentric wheel 411 is fixedly connected to the moving plate 410 through a return spring 413.

[0025] When the hand mold is positioned in the middle of the upper and lower hand mold 46, cylinder 1 43 is activated, causing the two mold seats 44 to move inward, which in turn causes the rotating arc plate 45 to move inward. The upper and lower hand mold 46 cover the hand mold. At this time, the absorbent cotton 414 will come into contact with the surface of the glove and absorb excess liquid on its surface. At the same time, the two half gears 47 are inserted together to form a whole. Then, cylinder 2 48 is activated, pushing the moving plate 410 to move, which causes the rack 3 412 to mesh with the half gear 47. Then, the rotary motor 49 is activated, driving the eccentric wheel 411 to rotate. Under the action of the return spring 413, the eccentric wheel 411 pushes the rack 3 412 to reciprocate, which in turn drives the half gear 47 to rotate, which in turn drives the rotating arc plate 45 and the hand mold 46 to rotate. Since the hand mold mounting mechanism 7 is rotating, it can drive the hand mold to rotate, which accelerates the absorption of liquid on the surface of the glove.

[0026] The hand mold mounting mechanism 7 includes a rotating shaft 71 rotatably mounted on a chain 2. A gear 72 is fixedly mounted on the rotating shaft 71. The gear 72 meshes with a horizontally arranged rack 41 inside the drying chamber 4, facilitating the rotation of the hand mold mounting mechanism 7. A mounting sleeve 73 is fixedly mounted at the end of the rotating shaft 71, and the mounting sleeve 73 is fixedly connected to the POM hand mold. An electromagnet is installed inside the mounting sleeve 73, and a magnet is installed at the end of the POM hand mold. When the electromagnet is energized, it generates magnetism, allowing the POM hand molds to be mounted together, facilitating disassembly and installation, and making it more convenient.

[0027] A folding roller 5 is provided on one side of the outer shell 1. A toothed rack 8 is horizontally arranged above the folding roller 5. By setting the folding roller 5, the glove at the wrist of the hand mold can be rolled up during the movement of the hand mold. In conjunction with the setting of the toothed rack 8, the hand mold can be driven to rotate continuously, so that the glove can be completely rolled up. This avoids the noise caused by air blowing in the prior art and also facilitates subsequent demolding.

[0028] A guide plate 6 is provided on one side of the rack 8. One end of the guide plate 6 is provided with an arc edge. A demolding machine is provided on one side of the guide plate 6. By setting the guide plate 6, the hand mold can be laid flat, which facilitates the subsequent demolding of the guide plate 6.

[0029] Working principle of the invention:

[0030] When the electromagnet is energized, it generates magnetism, allowing the POM hand mold to be mounted on the hand mold mounting mechanism 7. The chain 2 drives its rotation. When the hand mold is positioned between the upper and lower hand mold 46, cylinder 43 is activated, moving the two mold seats 44 inwards, which in turn moves the rotating arc plate 45 inwards. The upper and lower hand mold 46 then cover the hand mold. At this point, the absorbent cotton 414 contacts the glove surface, absorbing excess liquid. Simultaneously, the two half-gears 47 are inserted together to form a single unit, facilitating synchronized rotation. Then, cylinder 48 is activated, pushing the moving plate 410 to move, which in turn causes rack 412 to mesh with half gear 47. Then, rotary motor 49 is activated, driving eccentric wheel 411 to rotate. Under the action of return spring 413, eccentric wheel 411 drives rack 412 to reciprocate, which in turn drives half gear 47 to rotate, which in turn drives rotating arc plate 45 and hand mold 46 to rotate. Since the hand mold mounting mechanism 7 is rotating, it can drive the hand mold to rotate, which speeds up the adsorption of liquid on the surface of the glove, making it easier for subsequent drying and blowing.

[0031] Then, the hand mold is released, and the hand mold continues to move. Cold air is blown into the drying chamber 4 by the blower. The cooling air is guided by the S-shaped arc-shaped guide plate 42 to ensure that the cold air is in continuous contact with the nitrile gloves, resulting in a better drying effect. At the same time, during the drying process, the rack 41 makes it easier for the nitrile gloves to rotate continuously, making the contact more comprehensive, which will further improve the drying effect. The two steps work together to speed up the drying efficiency and improve the drying effect.

[0032] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
