Description

Technical Field

[0001] The present invention relates to the technical field of pre-treatment of molding materials, and particularly to a defoaming device for raw materials used in the production of protective gloves. Background Art

[0002] Gloves products mainly made of polyvinyl chloride are usually called PVC gloves. Polyvinyl chloride is a common plastic material with anti-static properties. In the actual production and processing of PVC gloves, since it involves the mixing of raw materials, a large number of bubbles are generated. Especially, polyvinyl chloride has a viscous property. If directly drawn out, it will directly affect the molding quality, causing the hollowing of the glove rubber surface and directly affecting the glove performance. Currently, defoaming agents are often used for natural defoaming or vacuum suction for defoaming.

[0003] Current vacuum defoaming equipment requires a relatively high amount of energy to drive the vacuum pump for suction during vacuum pumping. The more gas is extracted, the stronger the vacuum performance and the better the defoaming efficiency. However, at this time, the power of the vacuum pump and the consumption of energy also increase accordingly. After a barrel of raw materials is defoamed, the raw materials need to be output. At this time, external air will re-enter the equipment interior. After the next barrel of raw materials is injected into the equipment interior, the vacuum defoaming operation is carried out again. This results in the waste of the vacuum effect inside the cavity during the raw material switching process. The vacuum pump needs to repeatedly extract a large amount of gas for defoaming operation, increasing the energy consumption and production cost. For this reason, we propose a defoaming device for raw materials used in the production of protective gloves. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The raw material defoaming device for producing protective gloves provided by the present invention solves the problem that a large amount of external gas enters the equipment during the input and output of raw materials in the existing raw material defoaming device for producing protective gloves, resulting in a significant increase in the energy consumption of vacuum pumping. Pour the raw material to be defoamed into the feed hopper. The raw material is output to the corresponding conveying cavity through the output groove. At this time, the lifting ring is at the lower position. The first pipe on the lifting plate can communicate with the second pipe and the third pipe on the side, so that while the raw material is injected into the conveying cavity, the air on the upper side can be discharged to the outside through the third pipe. As the liquid level contacts the bottom surface of the lifting ring, the lifting ring is floated to drive the lifting plate to move upward, gradually releasing the communication between the first pipe and the second pipe. The lifting plate blocks the bottom end of the second pipe until the lifting ring reaches the top of the lifting groove. At this time, the raw material cannot continue to be input into the conveying cavity, and the feeding operation is completed. During this process, the gas at the top of the raw material is automatically discharged to the outside, greatly reducing the amount of air inside the chamber during the input process and reducing the energy consumption required for vacuum pumping.

[0016] 2. The defoaming device for raw materials used in the production of protective gloves provided by the present invention drives the switching column to rotate and switch through a driving motor until the conveying cavity filled with the raw materials to be defoamed reaches the side close to the vacuum tank. At this time, the fifth pipeline is connected to the sixth pipeline. At the same time, the driving block slides above the arc-shaped bottom surface on the upper sides of the outer ring and the inner ring, driving the lifting rod and the lifting frame to move upward, and the lifting disc also moves upward by a certain distance, creating a gap between the raw material liquid level and the lifting disc, avoiding directly pumping out the raw materials during vacuum pumping. This distance is relatively small, and the driving force required for the lifting disc to move upward is also relatively small. During the switching process, the output groove is disconnected from the communication groove. At this time, the vacuum tank will pump out the air above the device cavity through the air inlet pipe, and at the same time reduce the air pressure in the conveying cavity. The gas in the conveying cavity flows to the upper side of the lifting disc. At this time, starting the vacuum pump can pump out the small amount of air in the vacuum tank, the air inlet pipe, and the device cavity, reducing the energy consumption required for vacuum pumping.

[0017] 3. After the vacuum pumping is completed for the defoaming device for raw materials used in the production of protective gloves provided by the present invention, the driving motor is started again to drive the conveying cavity to rotate to the position connected to the output pipe. At this time, the driving block slides along the arc-shaped bottom surface to the lower side of the arc-shaped top surface, driving the lifting disc and the lifting ring to move downward. The fifth pipeline is disconnected from the sixth pipeline. At the same time, the second pipeline is connected to the fourth pipeline. As the raw materials are discharged from the output pipe at the bottom, the downward movement of the lifting ring makes the first pipeline connected to the second pipeline, and the outside gas can enter the upper area of the raw materials through the fourth pipeline, increasing the output speed of the raw materials and avoiding the situation that the raw materials are difficult to discharge due to air pressure reasons. After that, the empty conveying cavity is rotated to the set position so that the communication groove is connected to the bottom end of the output groove to perform repeated conveying and defoaming operations. Each time the position of the conveying cavity is switched, the input, defoaming, and output operations of the raw materials in different conveying cavities can be realized respectively, with a high degree of automation, greatly improving the production efficiency of protective gloves, and at the same time reducing the energy consumption during the vacuum pumping process, and the operation is more convenient and efficient.

[0035] The exhaust member 26 includes a lifting plate 28 fixedly mounted on the side of the lifting ring 23. A guide groove 29 is provided in the device chamber 14 and the conveying chamber 3 and is slidably connected to the lifting plate 28 in the vertical direction. A first pipe 30 is provided on the lifting plate 28, and a second pipe 31 that can be connected to the first pipe 30 is provided on the fixed column 13. A third pipe 32 and a fourth pipe 33 for connecting the second pipe 31 with the outside are provided on the fixed ring 17.

[0036] The lifting member 27 includes an outer ring 34 fixedly mounted on the mounting frame 18, an inner ring 35 fixedly connected to the outer wall of the hopper 9, a lifting rod 36 fixedly connected to the top of the lifting frame 21, the lifting rod 36 passes through the top of the fixed column 13, and is slidably connected to the fixed column 13 along the vertical direction, and a driving block 37 is fixedly connected to the top of the lifting rod 36. The upper and lower surfaces of the driving block 37 are both arc-shaped. The lifting rod 36 passes through the gap between the outer ring 34 and the inner ring 35, and the bottom surface of the driving block 37 slides and fits with the top surfaces of the outer ring 34 and the inner ring 35. The outer ring 34 and the inner ring 35 are provided with an adjusting member 38 for controlling the lifting and lowering movement of the driving block 37.

[0037] The adjusting member 38 includes an arcuate bottom surface 39 fixedly mounted on the outer ring 34 and the inner ring 35, and an arcuate top surface 40 is fixedly connected to the mounting frame 18, the arcuate bottom surface 39 is close to one side of the vacuum tank 6, and the arcuate top surface 40 is close to one side of the output groove 19, the top surface of the driving block 37 can be slidably fitted with the lower surface of the arcuate top surface 40, and the bottom surface of the driving block 37 can be slidably fitted with the upper surface of the arcuate bottom surface 39.

[0038] The vacuum mechanism 4 further includes a top plate 41 fixedly installed between the fixed ring 17 and the feed hopper 9. A fifth pipe 42 communicating with the intake pipe 7 is provided on the top plate 41. A plurality of groups of sixth pipes 43 communicating with the top end of the device cavity 14 are uniformly provided on the fixed column 13. The top surface of the sixth pipe 43 can communicate with the fifth pipe 42. The bottom surface of the top plate 41 is in sliding fit with the bottom surface of the fixed column 13. The lifting rod 36 penetrates the top plate 41 and is in sliding fit with the top plate 41.

[0039] In this implementation, the raw material to be defoamed is poured into the feed hopper 9. The raw material is output to the corresponding communication groove 20 through the output groove 19 and finally enters the conveying cavity 3. Here, the driving block 37 is located below the arc-shaped top surface 40, and the height of the lifting frame 21 is relatively low. At this time, the lifting ring 23 is at the lower position. The first pipe 30 on the lifting plate 28 can communicate with the second pipe 31 and the third pipe 32 on the side, so that while the raw material is injected into the conveying cavity 3, the air on the upper side can be discharged to the outside through the third pipe 32. As the liquid level contacts the bottom surface of the lifting ring 23, the lifting ring 23 is floated to drive the lifting plate 28 to move upward, gradually releasing the communication between the first pipe 30 and the second pipe 31. The lifting plate 28 blocks the bottom end of the second pipe 31 until the lifting ring 23 reaches the top end of the lifting groove 22. At this time, the raw material cannot continue to be input into the conveying cavity 3, and the feeding operation is completed. During this process, the gas at the top of the raw material is automatically discharged to the outside, greatly reducing the amount of air inside the chamber during the input process and reducing the energy consumption required for vacuum pumping.

[0040] The switching column 2 is driven to rotate and switch by the driving motor 48 until the conveying cavity 3 filled with the raw material to be defoamed reaches the side close to the vacuum tank 6. At this time, the fifth pipe 42 communicates with the sixth pipe 43. At the same time, the driving block 37 slides above the outer ring 34 and the inner ring 35 to above the arc-shaped bottom surface 39, driving the lifting rod 36 and the lifting frame 21 to move upward. The lifting disc 15 also moves upward by a certain distance, creating a gap between the raw material liquid level and the lifting disc 15 to prevent the raw material from being directly pumped out during vacuum pumping. This distance is relatively small, and the driving force required for the lifting disc 15 to move upward is also relatively small. During the switching process, the output groove 19 and the communication groove 20 are disconnected. At this time, the vacuum tank 6 will pump out the air on the upper side of the device cavity 14 through the intake pipe 7, and at the same time reduce the air pressure in the conveying cavity 3. The gas in the conveying cavity 3 pushes the sealing ball 47 upward and flows to the upper side of the lifting disc 15 through the second mounting ring 45 and the first mounting ring 44. At this time, the vacuum pump 5 is started to pump out the small amount of air in the vacuum tank 6, the intake pipe 7, and the device cavity 14, reducing the energy consumption required for vacuum pumping.

[0041] After the vacuum pumping is completed, the drive motor 48 is started again to drive the conveying chamber 3 to rotate to a position communicating with the output pipe 10. At this time, the drive block 37 slides along the arc-shaped bottom surface 39 to the lower side of the arc-shaped top surface 40, driving the lifting disc 15 and the lifting ring 23 to move downward. The fifth pipe 42 is disengaged from the sixth pipe 43, and at the same time, the second pipe 31 is communicated with the fourth pipe 33. As the raw material is discharged from the output pipe 10 at the bottom, the downward movement of the lifting ring 23 causes the first pipe 30 to be communicated with the second pipe 31, and the outside air can enter the upper region of the raw material through the fourth pipe 33, increasing the output speed of the raw material and avoiding the situation that the raw material is difficult to discharge due to air pressure reasons.

[0042] After that, the empty conveying chamber 3 is rotated to a set position so that the communication groove 20 is communicated with the bottom end of the output groove 19, and the repeated conveying and defoaming operations can be carried out. Each time the position of the conveying chamber 3 is switched, the input, defoaming and output operations of the raw materials in different conveying chambers 3 can be realized respectively. The degree of automation is high, greatly improving the production efficiency of the protective gloves. At the same time, the energy consumption during the vacuum pumping process is also reduced, and the operation is more convenient and efficient.

[0043] It should be noted that during the switching of the fixed column 13, when the fifth pipe 42 is not communicated with the sixth pipe 43, the top surface of the fixed column 13 will block the bottom surface of the fifth pipe 42, maintaining the vacuum state in the intake pipe 7 and the vacuum tank 6 until the next group of the sixth pipe 43 is communicated with the fifth pipe 42. There will be no situation where a large amount of gas enters the vacuum tank 6, ensuring that a large pumping intensity will be generated instantaneously when the fifth pipe 42 is communicated with the sixth pipe 43 during each vacuum pumping process. Only some relatively thin air needs to be pumped out later, while the traditional method needs to slowly pump a large amount of air inside to a thin state first, which takes a long time in this process and greatly reduces the production efficiency. Sealing rings can be set at both ends of all pipes of the device as needed, and the sealing performance at the joints at both ends of the pipes needs to be regularly checked when the conveying chamber is switched to avoid the overflow of gas and liquid.

[0044] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
