Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of PVC glove production equipment, and in particular to an oiling and lubricating device for PVC glove production. Background Art
[0002] PVC gloves are gloves produced with polyvinyl chloride as the main raw material. The main raw materials used include PVC paste resin, plasticizer, viscosity reducer, heat stabilizer, colorant and filler. PVC gloves have good anti-static properties and are suitable for semiconductor processing, food processing, vending and other industries.
[0003] The production process of PVC gloves mainly includes the following steps: 1. After the raw materials are fully stirred and mixed in a certain proportion, the liquid is obtained by filtering and the liquid is transferred to the dipping tank; 2. The hand mold is dipped in the dipping tank; 3. The hand mold after dipping is subjected to dripping treatment; 4. The hand mold is placed in an oven for plasticization after dripping; 5. The plasticized hand mold is placed in a polyurethane material tank for dipping and drying; 6. The glove blank after drying is subjected to lip rolling treatment; 7. The glove blank is detached from the hand mold to obtain the finished PVC gloves; 8. Inspection, packaging and storage.
[0004] In the production process of PVC gloves, the hand mold is installed on the hand mold seat, and the hand mold seat is connected to the conveyor chain to drive the hand mold to move with the conveyor chain; usually, the hand mold seat and the conveyor chain are rotatably connected through the hand mold seat bearing. After the hand mold is dipped in the dipping tank, the hand mold seat needs to roll forward along the auxiliary rail for a certain distance, so that the dipped material on the hand mold can be evenly distributed to ensure the uniform thickness of the formed PVC gloves. If the lubrication of the hand mold seat bearing is not in place, there will be the following effects: 1. During the rolling forward of the hand mold seat along the auxiliary rail, the hand mold seat is easy to lock, and the rolling friction between the hand mold seat and the auxiliary rail changes to sliding friction, the friction force increases, it is easy to damage the mold seat and the auxiliary rail, and reduce the uniformity of the distribution of the dipped material on the hand mold, affecting the quality of the PVC gloves; 2. When the hand mold is being rolled, the curling of the PVC gloves cannot be formed, resulting in waste; 3. When the glove blank is removed from the hand mold by the demoulding machine, the hand mold will hit the blow nozzle of the demoulding machine, resulting in batches of waste on the production line.
[0005] Therefore, in the production process of PVC gloves, ensuring the lubrication of the hand mold seat bearing is a very important process. In order to ensure the lubrication of the hand mold seat bearing, it is necessary to lubricate all the hand mold seat bearings regularly and quantitatively. The existing method is mainly to manually refuel the hand mold seat bearings that have passed by in sequence by holding an oiler. Not only is the workload huge, the working environment is harsh, and there are safety hazards for workers close to the high-speed transmission chain, but also the manual refueling method is difficult to ensure that the amount of oil for each hand mold seat bearing is appropriate, and the refueling and lubrication effect is not ideal; at the same time, since the production environment of PVC gloves is a high temperature and high humidity environment, when using electronic equipment to control refueling, there are problems such as easy failure and short service life; therefore, in view of the above problems, designing a device with high stability and reliability that can automatically and quantitatively refuel the hand mold seat bearings is a problem that PVC glove manufacturers at this stage urgently need to solve.

DETAILED DESCRIPTION
[0031] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.
[0032] Please refer to Figure 1-Figure 4 , which is an embodiment of an oiling and lubricating device for PVC gloves production provided by the present invention, comprising:
[0033] The conveying chain 1 is connected with a hand mold seat 11, and the hand mold seat 11 has a hand mold seat bearing 12. The hand mold is connected to the hand mold seat 11. When the hand mold is dipped in the dipping tank, the hand mold seat 11 can roll forward along the auxiliary rail through the hand mold seat bearing 12 under the drive of the conveying link;
[0034] The power take-off wheel 2 is meshed with the transmission chain 1. The transmission chain 1 can drive the power take-off wheel 2 to rotate while driving the hand model to move;
[0035] A refueling pipe 3, one end of which is connected to an oil cup 31, and the other end of the refueling pipe 3 is set as a refueling port 32, and the lubricating oil in the oil cup 31 can flow along the refueling pipe 3 and out of the refueling port 32;
[0036] The transmission assembly connects the power take-off wheel 2 with the oil filling port 32. The power take-off wheel 2 rotates through the transmission assembly to drive the oil filling port 32 to reciprocate between the first position and the second position. When in the first position, the oil filling port 32 is located directly above the hand mold seat bearing 12, and the hand mold seat bearing 12 is oiled and lubricated; when in the second position, the oil filling port 32 is away from the hand mold seat bearing 12.
[0037] The switch assembly, when the fuel filling port 32 is located at the first position, the switch assembly is in an open state so that the fuel filling pipe 3 is unobstructed and the lubricating oil can flow out from the fuel filling port 32; when the fuel filling port 32 is located at the second position, the switch assembly is in a closed state so that the fuel filling pipe 3 is blocked.
[0038] In one embodiment of the present invention, the transmission assembly includes a motion state conversion unit 42, which is connected to the power take-off wheel 2 and the refueling port 32 respectively, and converts the rotation of the power take-off wheel 2 into the swinging or linear reciprocating motion of the refueling port 32, that is, the rotation of the power take-off wheel 2 is used to realize the periodic reciprocating motion of the refueling port 32, so that the refueling port 32 can appear just above the hand mold seat bearing 12 at a fixed period and realize refueling and lubrication of the hand mold seat bearing 12; for details, please refer to Figure 1 and Figure 3 The motion state conversion unit 42 can be set as a crank rocker, and the crank part in the crank rocker can be connected to the power take-off wheel 2 by one or more combinations of gear meshing, shaft transmission, chain transmission, and belt transmission, so that the rocker part can be driven to achieve periodic reciprocating swing, and the refueling port 32 can be connected to the rocker part to achieve periodic reciprocating motion; in other embodiments, similarly, the motion state conversion unit 42 can also be set as a crank rocker block or a cam. The crank rocker block and the cam are both common mechanisms for converting rotation into periodic reciprocating motion, and both can realize the conversion of the rotation of the power take-off wheel 2 into periodic reciprocating motion of the refueling port 32.
[0039] On the basis of the above embodiment, a rotation steering unit 41 is further provided between the power take-off wheel 2 and the motion state conversion unit 42. The rotation steering unit 41 is connected to the power take-off wheel 2 and outputs a rotation direction different from that of the power take-off wheel 2, so as to facilitate connection with the motion state conversion unit 42. For details, please refer to Figure 1 and Figure 3The rotating steering part 41 is set to multiple and sequentially meshed direction-changing gears, which can change the rotation direction. The direction-changing gear and the power take-off wheel 2 can be connected by one or more combinations of gear meshing, shaft transmission, chain transmission, and belt transmission. Of course, the gear that changes the direction in the direction-changing gear can also be directly coaxial or meshed with the rotating shaft of the crank in the crank rocker to directly drive the crank to rotate. The number and size of the direction-changing gears are based on ensuring that the refueling port 32 can reciprocate periodically at a suitable position; in other embodiments, similarly, the rotating steering part 41 can also be set to a worm gear, which is a common mechanism for changing the rotation direction of a worm gear.
[0040] In one embodiment of the present invention, please refer to Figure 1-Figure 4 A guide assembly 6 for guiding the movement of the fuel filling port 32 is provided at one end of the fuel filling pipe 3 close to the fuel filling port 32. The guide assembly 6 is used to limit the fuel filling port 32 so that the fuel filling port 32 reciprocates along a fixed trajectory periodically.
[0041] Based on the above examples, please refer to Figure 2 and Figure 4 , a shaping component 7 for fixing the shape of the refueling pipe 3 is provided at one end of the refueling pipe 3 near the refueling port 32, and the shaping component 7 can ensure that the portion of the refueling pipe 3 near the refueling port 32 will not change its shape during the periodic reciprocating motion, so as to avoid affecting the normal outflow of lubricating oil; the refueling pipe 3 is connected to the transmission component through the shaping component 7, and the transmission component connection drives the refueling port 32 to move indirectly by driving the shaping component 7 to move; the shaping component 7 is movably connected to the guide component 6, and the shaping component 7 and the refueling port 32 can synchronously reciprocate periodically under the limit of the guide component 6; specifically, the guide component 6 can be set as a sleeve with a hollow pipe, the shaping component 7 is set as a rod and part of the shaping component 7 extends into the hollow pipe, and through the limit of the sleeve, the shaping component 7 and the refueling port 32 can only reciprocate periodically along the axial direction of the hollow pipe; in other embodiments, the guide component 6 can also be set as a slideway or a slide rail, and the shaping component 7 is set as a slider matching the guide component 6, which can also make the refueling port 32 move reciprocatingly along a specific path.
[0042] Based on the above examples, please refer to Figure 2 and Figure 4The switch assembly is arranged on the fuel filling pipe 3 or on the guide assembly 6 or between the fuel filling pipe 3 and the guide assembly 6, that is, the switch assembly can control the smoothness or blockage of the pipeline of the fuel filling pipe 3 by a switch mode inside the fuel filling pipe 3 or by a pressure mode from the outside of the fuel filling pipe 3; further, the switch assembly includes a baffle 51 which is arranged at the fuel filling port 32 and blocks the fuel filling port 32, and the baffle 51 is rotatably connected to the shaping assembly 7. A baffle 52 is arranged on the guide assembly 6. When the fuel filling port 32 is located at the first position, the baffle 52 abuts against the baffle 51 and causes the baffle 51 to rotate. The fuel filling pipe 3 is unobstructed, and the lubricating oil flows out from the fuel filling port 32 and drips onto the hand mold seat bearing 12. When the fuel filling port 32 leaves the first position, the baffle 51 is separated from the baffle block 52, and the baffle 51 can be reset to block the fuel filling port 32. Specifically, the baffle 51 can be automatically reset by setting a reset spring on the rotating shaft of the baffle 51. In other embodiments, the baffle 51 can also be arranged between the fuel filling pipe 3 and the guide assembly 6, and the baffle 51 is used to change the pressure of the baffle 51 on the fuel filling pipe 3 to control the smoothness or blockage of the pipeline of the fuel filling pipe 3.
[0043] It should be noted that in the specific implementation process of the present invention, it is necessary to reasonably determine the specifications of the power take-off wheel 2, the diameter of the refueling pipe 3, the combination and specifications of the transmission components, the setting position of the switch component and other parameters according to the actual situation in the production of PVC gloves, combined with factors such as the transmission speed of the conveying chain 1, the distance between adjacent hand mold seat bearings 12, the amount of lubricating oil that needs to be dripped on the hand mold seat bearing 12 at a time, and the time for the conveying chain 1 to transmit one circle, so as to ensure that when the conveying chain 1 is transmitted normally, when each hand mold seat bearing 12 passes through the refueling port 32, the refueling port 32 is located at the first position, and the amount of lubricating oil dripped by the refueling port 32 to each hand mold seat bearing 12 should just ensure the lubrication of the hand mold seat bearing 12 for one cycle on the conveying chain 1.
[0044] It should be noted that in actual production, the hand molds (left hand mold and right hand mold) are usually symmetrically arranged based on the transmission chain 1. The refueling pipe 3, transmission assembly, switch assembly, etc. in the present invention should also be symmetrically arranged based on the transmission chain 1. The transmission assemblies on both sides can be connected to the power take-off wheel 2 at the same time, so as to realize the simultaneous refueling and lubrication of the hand mold seat bearings 12 on both sides of the transmission chain 1.
[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
