Technical Field

[0001] The invention belongs to the technical field of protective equipment production, and specifically relates to a nitrile latex composite material for protective equipment production and a preparation method thereof. Background Art

[0002] Nitrile latex composite materials for the production of protective equipment are a high-performance material. Due to its excellent physical properties and chemical stability, they are widely used in the production of protective equipment such as gloves and protective clothing. Nitrile latex composite materials are mainly composed of nitrile latex, various additives and emulsifiers. These ingredients are mixed and processed through a specific process to form a material with excellent performance.

[0003] Mixing nitrile latex composite materials requires stirring equipment, which usually includes a stirring drum, a stirring mechanism and a control system. The stirring drum is used to contain the raw materials to be mixed, and the stirring mechanism mixes the raw materials evenly by rotating or stirring.

[0004] However, the conventional device still has the following problems when used:

[0005] Due to the existing technology, when mixing materials, the mixing of materials is driven only by the rotation of the stirring rod. In this case, the materials are prone to local accumulation and stratification, resulting in insufficient mixing uniformity. Especially when the material viscosity is high or the particles are large, the stirring rod cannot effectively bring the material from the bottom or edge of the mixing box to the center area, thus affecting the mixing effect.

[0037] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings.

[0039] Embodiment 2, on the basis of embodiment 1, the nitrile latex composite material for producing protective equipment includes a mounting frame 1, the mounting frame 1 is rotatably connected to a stirring box 2, the outer wall of the top of the mounting frame 1 is fixedly connected to a U-shaped support frame, the inner wall of the bottom of the U-shaped support frame is fixedly connected to a motor 21, the outer wall of the top of the stirring box 2 is fixedly connected to a feed pipe 4, the middle position of the top outer wall of the stirring box 2 is rotatably connected to a main shaft 22, the outer wall of the top of the main shaft 22 is fixedly connected to the output end of the motor 21, the upper part of the outer wall of the main shaft 22 is rotatably connected to a mounting sleeve 32, the outer wall of the main shaft 22 is fixedly connected to a main bevel gear 23, the outer wall of the top of the stirring box 2 is fixedly connected to a support rod 42, and the two support rods 42 are provided with round holes, and the round holes are provided on the two support rods 42. A connecting shaft 43 is rotatably connected inside the hole, a secondary bevel gear 41 is fixedly connected to the outer wall of one end of the right connecting shaft 43, a secondary bevel gear 2 44 is fixedly connected to the outer wall of one end of the left connecting shaft 43, the outer wall of the secondary bevel gear 2 44 is meshed and connected with the outer wall of the main bevel gear 23, the outer wall of the secondary bevel gear 41 is meshed and connected with the outer wall of the main bevel gear 23, the outer walls of the opposite ends of the two connecting shafts 43 are fixedly connected to eccentric wheels, the outer walls of the opposite sides of the two eccentric wheels are fixedly connected to connecting rods 45, the outer wall of the connecting rod 45 is rotatably connected to a mounting rod 46, a limiting groove is provided at the bottom of the mounting rod 46, a rotating shaft 47 is rotatably connected inside the limiting groove, a stirring blade 48 is fixedly connected to the lower part of the outer wall of the rotating shaft 47,

[0040] Through the movement of the eccentric wheel, the mounting rod 46 can drive the rotating shaft 47 to move up and down inside the feed pipe 4. Through the up and down movement of the rotating shaft 47, the raw materials entering the feed pipe 4 can be pushed, thereby avoiding the accumulation or blockage of the raw materials in the feed pipe 4, and correspondingly improving the efficiency of the raw materials entering 2.

[0041] Embodiment 3, on the basis of embodiment 2, a threaded path is opened above the outer wall of the rotating shaft 47, the outer wall of the rotating shaft 47 is threadedly connected with a nut 49 at the position of the threaded path, the outer walls on both sides of the nut 49 are fixedly connected with T-shaped rods 411, the outer walls at opposite ends of the two T-shaped rods 411 are slidably connected with a limiting shell 410, and the opposite outer walls of the two limiting shells 410 are fixedly connected to the inner wall of the feed pipe 4.

[0042] The rotation of the rotating shaft 47 can drive the stirring blade 48 to rotate inside the feeding pipe 4. The rotation of the stirring blade 48 can stir the raw materials entering the feeding pipe 4. The stirring blade 48 performs preliminary stirring on the raw materials, which helps to evenly disperse the raw materials and provides better conditions for subsequent mixing in the stirring box 2.

[0043] Since the T-shaped rod 411 slides horizontally on the limit shell 410, when the eccentric wheel drives the rotating shaft 47 to deviate inside the feed pipe 4, the nut 49 can adjust its position along with the movement of the rotating shaft 47, thereby preventing the rotating shaft 47 from tilting inside the nut 49, which may easily cause damage to the nut 49 or the rotating shaft 47. Accordingly, the sliding adjustment function of the T-shaped rod 411 ensures that the nut 49 can fit tightly with the rotating shaft 47, thereby preventing the rotating shaft 47 from tilting inside the nut 49.

[0044] Embodiment 4, on the basis of embodiment 3, the three square grooves 5 are internally slidably connected with an F-shaped limit plate 51, the outer wall on one side of the F-shaped limit plate 51 is provided with a T-shaped groove 52, the inner slidably connected with an H-shaped slider 53, the outer wall on one side of the H-shaped slider 53 is fixedly connected with a push spring 54, the outer wall at one end of the push spring 54 is fixedly connected with the inner part of the square groove 5, the outer wall at the bottom of the F-shaped limit plate 51 is fixedly connected with a T-shaped block 56, the outer wall at the top of the bevel gear three 33 is provided with a slide groove two 55, the interior of the three slide grooves two 55 is slidably connected with the outer wall of the T-shaped block 56, and the outer wall of the bevel gear three 33 is meshedly connected with the outer wall of the auxiliary bevel gear one 41.

[0045] After the bevel gear three 33 is pushed and connected with the auxiliary bevel gear one 41 by the F-shaped limit plate 51, the adjusting plate 34 can be rotated in the opposite direction, so that the track 36 pushes the adjusting rod 37 to return to its original position, and then the F-shaped limit plate 51 drives the bevel gear three 33 to be fixed on the connecting plate 3 by setting the push spring 54, so that the bevel gear three 33 can be fixed, thereby ensuring the stability of the engagement between the bevel gear three 33 and the auxiliary bevel gear one 41. By adjusting the engagement or separation of the bevel gear three 33 and the auxiliary bevel gear one 41, it can be flexibly adjusted according to different mixing requirements and material characteristics, and the movement of the mixing box 2 is correspondingly more flexible.

[0046] Embodiment 5, on the basis of embodiment 4, a connecting plate 3 is fixedly connected to the upper part of the outer wall of the mounting sleeve 32, a bevel gear three 33 is slidably connected to the lower part of the outer wall of the mounting sleeve 32, strip grooves are provided on both sides of the outer wall of the mounting sleeve 32, a first limit block 35 is fixedly connected to the inner wall of the bevel gear three 33, the outer walls of the two first limit blocks 35 are slidably connected to the inner part of the strip groove, a force-bearing rod 31 is fixedly connected to the outer wall of the bottom of the connecting plate 3, the outer walls of the bottoms of the three force-bearing rods 31 are fixedly connected to the outer wall of the top of the mixing box 2, and a square groove 5 is provided on the outer wall of the top of the connecting plate 3.

[0047] By rotating the connecting plate 3, the force-bearing rod 31 can drive the mixing box 2 to rotate. The rotation of the mixing box 2 enables the materials therein to be mixed more fully and evenly, avoiding the problem that the materials at the bottom or edge of the mixing box cannot be stirred by the rotation of the stirring rod alone. The corresponding rotation of the mixing box 2 can effectively promote the mutual movement and collision between the raw materials, thereby enhancing the mixing effect. The rotation of the mixing box 2 can then be used to fully stir and disperse the materials originally deposited at the bottom or edge of the mixing box 2, ensuring that the materials in the entire mixing box 2 can be evenly mixed. Compared with static mixing or simple stirring methods, rotating the mixing box 2 can achieve material mixing more quickly, thereby shortening the production cycle and improving production efficiency. At the same time, rotating the mixing box 2 can also reduce the adhesion and agglomeration of materials during the mixing process, further improving the mixing efficiency.

[0048] Embodiment 6. On the basis of embodiment 3, a slide groove 342 is provided on the outer wall at the top of the mounting sleeve 32, a slide groove 342 is internally movably connected with a slide rod 341, an outer wall at the top of the slide rod 341 is fixedly connected with an adjustment plate 34, a track 36 is provided on the outer wall at the top of the adjustment plate 34, an adjustment rod 37 is slidably connected inside the three tracks 36, an outer wall at the bottom of the adjustment rod 37 is fixedly connected with the outer wall at the top of the F-shaped limit plate 51, a telescopic limit block 38 is fixedly connected with the outer wall at the top of the F-shaped limit plate 51, a circular hole is provided on the outer wall at the top of the connecting plate 3, and the outer wall of the telescopic limit block 38 is movably plugged into the inside of the circular hole.

[0049] The adjusting plate 34 drives the slide bar 341 to slide upward inside the slide groove 1 342. When the round hole on the adjusting plate 34 leaves the telescopic limit block 38, the adjusting plate 34 can be rotated to make the round hole deviate from the telescopic limit block 38. At this time, the limit between the telescopic limit block 38 and the adjusting plate 34 is released, so that the adjusting plate 34 can work. This operation saves the operator's time to release the fixing of the adjusting plate 34.

[0050] When the adjusting plate 34 is forced to move downward, a thrust is generated on the F-shaped limit plate 51, so that multiple F-shaped limit plates 51 move downward at the same time. The downward movement of the F-shaped limit plate 51 can cause the bevel gear three 33 to move downward accordingly, so that the bevel gear three 33 is meshed and connected with the auxiliary bevel gear one 41, avoiding the need for the operator to push the F-shaped limit plate 51 downward one by one, and correspondingly making the bevel gear three 33 quickly meshed and connected with the auxiliary bevel gear one 41, further saving the operator's adjustment time for the bevel gear three 33.

[0051] The working principle and use process of the present invention are as follows: when working, first, after the motor 21 is started to work, the raw materials of the prepared nitrile latex composite material are put into the interior of the mixing box 2 from the feed pipe 4. At this time, the main shaft 22 can drive the main bevel gear 1 23 to rotate through the operation of the motor 21, and then the meshing connection between the auxiliary bevel gear 1 41 and the auxiliary bevel gear 2 44 and the main bevel gear 1 23 is utilized. When the main bevel gear 1 23 rotates, the auxiliary bevel gear 1 41 and the auxiliary bevel gear 2 44 can be driven to rotate at the same time, and then By rotating the auxiliary bevel gear 1 41 and the auxiliary bevel gear 2 44, the connecting shaft 43 can be driven to rotate on the support rod 42. As the connecting shaft 43 rotates, the eccentric wheel can drive the connecting rod 45 to rotate. Through the movement of the eccentric wheel, the mounting rod 46 can drive the rotating shaft 47 to move up and down inside the feed pipe 4. Through the up and down movement of the rotating shaft 47, the raw materials entering the feed pipe 4 can be pushed, thereby avoiding the accumulation or blockage of the raw materials in the feed pipe 4, and correspondingly improving the efficiency of the raw materials entering 2.

[0052] When the rotating shaft 47 moves up and down inside the feed pipe 4, the threaded connection between the nut 49 and the thread on the rotating shaft 47 can be used to make the rotating shaft 47 rotate inside the nut 49 by utilizing the spiral shape of the thread. Then, the rotation of the rotating shaft 47 can drive the stirring blade 48 to rotate inside the feed pipe 4. The rotation of the stirring blade 48 can stir the raw materials entering the feed pipe 4. The preliminary stirring of the raw materials by the stirring blade 48 helps to evenly disperse the raw materials, providing better conditions for subsequent mixing in the stirring box 2.

[0053] Through the cooperation between the limit shell 410 and the T-shaped rod 411, the T-shaped rod 411 can fix the nut 49, thereby preventing the nut 49 from rotating with the rotation of the rotating shaft 47. Accordingly, the nut 49 is fixed, and the thread on the rotating shaft 47 and the thread inside the nut 49 can maintain effective engagement, thereby ensuring that the rotating shaft 47 can rotate inside the nut 49.

[0054] Since the T-shaped rod 411 slides horizontally on the limit shell 410, when the eccentric wheel drives the rotating shaft 47 to deviate inside the feed pipe 4, the nut 49 can adjust its position along with the movement of the rotating shaft 47, thereby preventing the rotating shaft 47 from tilting inside the nut 49, which may easily cause damage to the nut 49 or the rotating shaft 47. Accordingly, the sliding adjustment function of the T-shaped rod 411 ensures that the nut 49 can fit tightly with the rotating shaft 47, thereby preventing the rotating shaft 47 from tilting inside the nut 49.

[0055] It should be noted that the size of the secondary bevel gear 44 is smaller than that of the secondary bevel gear 41 .

[0056] After the raw materials enter the mixing box 2, the main shaft 22 can be used to drive the mixing rod to mix the raw materials. When the mixing effect of the raw materials needs to be increased, first, the operator holds the adjusting plate 34 with his hand and lifts it upward, and then through the upward movement of the adjusting plate 34, the adjusting plate 34 can drive the sliding rod 341 to slide upward in the sliding groove 342. When the circular hole on the adjusting plate 34 leaves the telescopic limit block 38, the adjusting plate 34 can be rotated to make the circular hole deviate from the telescopic limit block 38. At this time, the limit of the telescopic limit block 38 and the adjusting plate 34 is released, so that the adjusting plate 34 can work. This operation saves the operator's time to release the fixation of the adjusting plate 34.

[0057] It should be noted that, since the telescopic limit block 38 has a telescopic function, when the adjustment plate 34 is pressed on the telescopic limit block 38 , the telescopic limit block 38 can enter into the interior of the F-shaped limit plate 51 .

[0058] After the circular hole contacts the telescopic limit block 38, the adjusting plate 34 is placed to fit the top of the F-shaped limit plate 51 and the adjusting plate 34 is rotated according to the operator's habit, or the adjusting plate 34 is continued to be lifted and rotated. This flexibility makes the operation more convenient and adapts to the operating habits of different operators. By rotating the adjusting plate 34, the track 36 can be driven to push the adjusting rod 37. When the adjusting rod 37 is forced to move, the F-shaped limit plate 51 can be driven to move inside the square groove 5, thereby releasing the fixation of one side of the F-shaped limit plate 51 stuck on the top of the connecting plate 3. When the F-shaped limit plate 51 and the connecting plate are released, 3, the adjusting plate 34 can be pressed downward, and when the adjusting plate 34 is forced to move downward, a thrust is generated on the F-shaped limiting plate 51, so that multiple F-shaped limiting plates 51 move downward at the same time, and the downward movement of the F-shaped limiting plate 51 can make the bevel gear three 33 move downward accordingly, so that the bevel gear three 33 is meshed and connected with the auxiliary bevel gear one 41, avoiding the need for the operator to push the F-shaped limiting plates 51 downward one by one, and correspondingly making the bevel gear three 33 quickly meshed and connected with the auxiliary bevel gear one 41, further saving the operator's adjustment time for the bevel gear three 33.

[0059] When the F-shaped limit plate 51 slides upward inside the square groove 5, the F-shaped limit plate 51 can slide on the H-shaped slider 53 through the cooperation of the H-shaped slider 53 and the T-shaped groove 52, so that the push spring 54 drives the H-shaped slider 53 to be fixed in place, avoiding the push spring 54 and the square groove 5 being fixedly connected to affect the movement of the F-shaped limit plate 51, and correspondingly increasing the smoothness of the movement of the F-shaped limit plate 51 inside the square groove 5. When the F-shaped limit plate 51 stops moving, the push spring 54 pushes the H-shaped slider 53 to fix the F-shaped limit plate 51.

[0060] After the bevel gear three 33 is pushed and connected with the auxiliary bevel gear one 41 by the F-shaped limit plate 51, the adjusting plate 34 can be rotated in the opposite direction, so that the track 36 pushes the adjusting rod 37 to return to its original position, and then the F-shaped limit plate 51 drives the bevel gear three 33 to be fixed on the connecting plate 3 by setting the push spring 54, so that the bevel gear three 33 can be fixed, thereby ensuring the stability of the engagement between the bevel gear three 33 and the auxiliary bevel gear one 41. By adjusting the engagement or separation of the bevel gear three 33 and the auxiliary bevel gear one 41, it can be flexibly adjusted according to different mixing requirements and material characteristics, and the movement of the mixing box 2 is correspondingly more flexible.

[0061] When the adjusting plate 34 is restored to its original position, the circular hole can be aligned with the telescopic limit block 38, so that the telescopic limit block 38 can be inserted into the inside of the circular hole, and the adjusting plate 34 can be limited, thereby avoiding the adjustment plate 34 from moving under the action of external force, and correspondingly ensuring the stability of the adjustment plate 34.

[0062] After the bevel gear three 33 is meshed and connected with the auxiliary bevel gear one 41, the auxiliary bevel gear one 41 can drive the bevel gear three 33 to rotate. Through the first limit block 35 and the limit of the bar groove set inside the bevel gear three 33, when the bevel gear three 33 rotates, the first limit block 35 can drive the mounting sleeve 32 to rotate, so that the connecting plate 3 moves accordingly. Then, through the rotation of the connecting plate 3, the force-bearing rod 31 can drive the mixing box 2 to rotate. The rotation of the mixing box 2 allows the materials therein to be more fully mixed and evenly mixed, avoiding the problem that the materials at the bottom or edge of the mixing box cannot be driven by the rotation of the stirring rod alone. The materials are stirred, and the corresponding rotation of the stirring box 2 can effectively promote the mutual movement and collision between the raw materials, thereby enhancing the mixing effect. The rotation of the stirring box 2 can then make the materials originally deposited at the bottom or edge of the stirring box 2 be fully stirred and dispersed, ensuring that the materials in the entire stirring box 2 can be evenly mixed. Compared with static mixing or simple stirring methods, rotating the stirring box 2 can achieve material mixing more quickly, thereby shortening the production cycle and improving production efficiency. At the same time, rotating the stirring box 2 can also reduce the adhesion and agglomeration of materials during the mixing process, further improving the mixing efficiency.

[0063] It should be noted that: through the cooperation between the T-shaped block 56 and the second slide groove 55, when the F-shaped limit plate 51 moves upward, the T-shaped block 56 can drive the bevel gear three 33 to move upward, thereby completing the separation of the bevel gear three 33 and the auxiliary bevel gear one 41.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
