Description

Technical Field

[0001] This invention relates to the field of rubber glove production equipment, specifically a hand mold fixing device and its installation method for producing soft nitrile gloves. Background Technology

[0002] Nitrile gloves are gloves made or coated with a protective coating that provides oil resistance. They are primarily used in factories, oil fields, and repair shops. Nitrile gloves do not contain latex protein, so they do not cause allergic reactions. They also possess antistatic, aging-resistant, and oil-resistant properties. Furthermore, nitrile gloves are designed to fit the human hand shape, offering excellent dexterity, good tensile strength and puncture resistance, high tensile strength, and excellent abrasion resistance.

[0003] The production of nitrile gloves requires the use of hand molds. The main function of the hand mold is to be installed on the conveyor chain, requiring it to fit the molded nitrile gloves while also moving with the conveyor chain, sequentially passing through the immersion chamber, drying chamber, and unmolding chamber. During the movement of the nitrile gloves, the hand mold must be able to switch the gloves' tilt angles, and in the immersion chamber, the immersed nitrile gloves should not easily fall off. In the unmolding chamber, the rubber gloves fitted onto the hand mold should be able to be easily removed.

[0004] To address the problems mentioned above in the background art, the present invention aims to provide a hand mold fixing device and its installation method for the production of soft nitrile gloves. Summary of the Invention

A hand mold is fixedly installed at the middle position of the lower end of the mounting base, and baffles are movably installed on the left and right sides of the lower end of the hand mold. A nitrile glove is fitted on the hand mold.

[0009] As a further aspect of the present invention: the end is provided with a hook, the angle of which is controlled between 30° and 45°, and the hook provided on the end and the inner side of the end form a movable groove.

[0010] As a further aspect of the present invention: a U-shaped frame is movably mounted on the lower end of the pull rod via a crank, and there are two cranks, which are distributed on the front and rear sides of the pull rod. The upper ends of the two cranks are hinged and movably mounted at the connection position with the pull rod via pins, and the lower ends of the two cranks are respectively rotatably mounted on the left and right sides of the upper end of the U-shaped frame.

[0011] As a further aspect of the present invention: the lower middle end of the mounting base is provided with a threaded end, and the upper end of the hand mold is provided with a threaded section at the position directly opposite the threaded end.

[0012] As a further embodiment of the present invention: the baffle is slidably installed inside the hand mold, one side of the front end of the baffle is coated with a smooth material layer, and the other end of the baffle is provided with a movable rod, which is slidably installed inside the fixed cylinder, and the fixed cylinder is set inside the hand mold; a movable block is provided on the end part of the movable rod that extends into the fixed cylinder, the movable block is slidably installed inside the fixed cylinder, a compression spring is provided on the part of the movable rod between the baffle and the movable block, and the other end of the movable block is connected to the inner wall of the fixed cylinder through a shock-absorbing spring.

[0013] The installation method of the hand mold fixing device for producing soft nitrile gloves includes the following steps:

[0014] 1. The hand mold is installed by means of thread and groove mating between the threaded section at the upper end of the hand mold and the threaded end at the lower end of the mounting base. The hand mold is then positioned at the lower end of the mounting base.

[0015] Second, the tie rod and the U-shaped frame are then connected by a crank for a movable installation.

[0016] Third, the nitrile gloves were then placed over the hand mold;

Detailed Implementation

[0028] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention. Example

[0029] Please see Figure 1 , Figure 2 and Figure 3This invention provides a hand mold fixing device for producing soft nitrile gloves, the hand mold fixing device for producing soft nitrile gloves includes:

[0030] The device comprises an end cap 1, a pull rod 2, a sleeve 6, a sleeve rod 8, a mounting base 10, and a hand mold 12. The end cap 1 is designed in a hook shape. A pull rod 2 is fixedly installed at the lower end of the end cap 1. A U-shaped frame 5 is movably installed at the lower end of the pull rod 2. The lower end of the U-shaped frame 5 is integrally formed with the sleeve 6. A sleeve rod 8 is movably installed inside the sleeve 6. A sliding piece 7 is installed on the end portion of the sleeve rod 8 that extends into the sleeve 6. A roller 9 is provided at the middle position of the sleeve rod 8. A mounting base 10 is provided at the bottom end of the sleeve rod 8. Baffles 11 are provided on the left and right sides of the lower end of the mounting base 10. A hand mold 12 is fixedly installed at the middle position of the lower end of the mounting base 10. Baffles 18 are movably installed on the left and right sides of the lower end of the hand mold 12. A nitrile glove 13 is fitted on the hand mold 12.

[0031] When the hand mold fixing device for producing soft nitrile gloves is used, after the nitrile glove 13 is fitted onto the outer surface of the hand mold 12, the baffles 18 that are movably installed on both sides of the hand mold 12 protrude outwards. Through the cooperation with the baffles 11 provided on the left and right sides of the lower end of the mounting base 10, the nitrile glove 13 fitted onto the hand mold 12 can be automatically clamped and fixed.

[0032] After the nitrile glove 13 fitted onto the hand mold 12 is clamped and fixed, the entire hand mold fixing device can be movably mounted on the crossbar of the conveyor chain through the end 1. During the displacement of the end 1 driven by the conveyor chain, the nitrile glove 13 fitted at the lower end of the hand mold 12 can also achieve displacement transmission at the same time, and the roller 9 installed on the sleeve 8 rolls and moves in the track. When adjusting the tilt angle of the nitrile glove 13, the roller 9 changes track in the track, thereby changing the tilt of the entire hand mold fixing device. At the same time, the sliding piece 7 slides and moves inside the sleeve 6, moving to a certain distance according to the tilt angle of the track change, while the sliding piece 7 installed at the upper end of the sleeve 8 is rotated and installed inside the sleeve 6.

[0033] At the same time, the end 1 is rotated on the crossbar installed at the upper end of the conveyor chain to change the inclination of the end 1, and then the position is adjusted reasonably according to the inclination of the track change.

[0034] Please see Figure 2In one embodiment of the present invention, the end 1 is provided with a hook 14, the angle range of the hook 14 is controlled between 30° and 45°, and the hook 14 provided on the end 1 forms a movable groove 15 with the inner side of the end 1; when using the end 1, it can be hooked and suspended on the conveyor chain by the hook 14 provided on the end 1, thereby driving the entire hand mold fixing device to move. Moreover, the movable groove 15 can be opened later to realize the movement on the horizontal axis of the conveyor chain, and the tilt angle position of the entire hand mold fixing device can be switched.

[0035] In one embodiment of the present invention, the lower end of the pull rod 2 is movably mounted with a U-shaped frame 5 via a crank 4. There are two cranks 4, which are distributed on the front and rear sides of the pull rod 2. The upper ends of the two cranks 4 are hinged and movably mounted at the connection position with the pull rod 2 via a pin 3. The lower ends of the two cranks 4 are respectively rotatably mounted on the left and right sides of the upper end of the U-shaped frame 5.

[0036] By installing a crank 4 and a U-shaped frame 5 at the connection point between the pull rod 2 and the sleeve 6, compared with the traditional method of directly connecting the pull rod 2 and the sleeve 6, the entire hand mold fixing device can have better mobility. When the tilt angle of the hand mold fixing device is changed by changing the track, the crank 4 and the U-shaped frame 5 installed between the pull rod 2 and the sleeve 6 can also rotate mechanically and flexibly, so that the upper end of the end 1 can switch the angle position of the lower end of the hand mold fixing device without rotating.

[0037] In one embodiment of the present invention, the lower middle end of the mounting base 10 is provided with a threaded end 16, and the upper end of the hand mold 12 is provided with a threaded section 17 directly opposite the threaded end 16. When the hand mold 12 is assembled with the mounting base 10, the threaded section 17 provided on the upper end of the hand mold 12 and the threaded end 16 installed on the lower end of the mounting base 10 are connected by a thread and a thread groove to achieve movable installation, so as to achieve easy disassembly and assembly.

[0038] Please see Figure 4 In one embodiment of the present invention, the baffle 18 is slidably installed inside the hand mold 12. A smooth material layer 19 is coated on one side of the front end of the baffle 18, and a movable rod 22 is provided at the other end of the baffle 18. The movable rod 22 is slidably installed inside the fixed cylinder 20, which is located inside the hand mold 12. A movable block 23 is provided on the end portion of the movable rod 22 that extends into the fixed cylinder 20. The movable block 23 is slidably installed inside the fixed cylinder 20. A compression spring 21 is provided on the portion of the movable rod 22 between the baffle 18 and the movable block 23. The other end of the movable block 23 is connected to the inner wall of the fixed cylinder 20 through a shock-absorbing spring 24. The elastic deformation of the shock-absorbing spring 24 is greater than that of the compression spring 21.

[0039] When the nitrile glove 13 is fitted onto the hand mold 12, the inside of the nitrile glove 13 is pushed open by the baffles 18 that are movably installed on both sides of the hand mold 12, and works in conjunction with the baffle 11 to clamp and fix the nitrile glove 13 fitted onto the hand mold 12; since the elastic deformation of the shock-absorbing spring 24 is greater than that of the compression spring 21, the thrust generated by the deformation is greater than the reverse force generated by the compression spring 21, causing the movable rod 22 to push the baffles 18 out of the outside of the hand mold 12. Since the outer surface of the baffles 18 is provided with a smooth material layer 19, the nitrile glove 13 can be easily fitted onto the outside of the hand mold 12;

[0040] Moreover, when the nitrile glove 13 is put on, the operator will apply force to the smooth material layer 19, squeezing the baffle 18 to extend and retract into the hand mold 12, thereby pushing the movable block 23 to slide and move inside the fixed cylinder 20, so that the elastic force generated by the deformation of the shock-absorbing spring 24 and the compression spring 21 can push the baffle 18 back to the initial state, thus clamping and fixing the nitrile glove 13 put on the hand mold 12.

[0041] The installation method of the hand mold fixing device for producing soft nitrile gloves includes the following steps:

[0042] 1. The hand mold 12 is installed in a movable manner by means of thread and thread groove engagement between the threaded section 17 at the upper end of the hand mold 12 and the threaded end 16 at the lower end of the mounting base 10, so that the hand mold 12 is set at the lower end of the mounting base 10.

[0043] Second, the tie rod 2 and the U-shaped frame 5 are then movably installed using the crank 4;

[0044] Third, the nitrile gloves 13 are then placed on the hand mold 12;

[0045] Fourth, the entire hand mold fixing device for the production of soft nitrile gloves is suspended on the conveyor chain through the set end 1;
