Description

Technical Field

[0001] The invention relates to the technical field of molding material pretreatment, in particular to a raw material degassing device for producing protective gloves. Background Art

[0002] Gloves made of polyvinyl chloride as the main raw material 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, because it involves mixing of raw materials, a large number of bubbles are generated. In particular, polyvinyl chloride also has the characteristic of being sticky. If it is directly drawn out, it will directly affect the molding quality and cause hollowing of the rubber surface of the gloves, which directly affects the performance of the gloves. At present, defoaming agents are often used for natural defoaming or vacuum suction to remove bubbles.

[0003] The current vacuum degassing equipment consumes a lot of energy to drive the vacuum machine for suction when vacuuming. The more gas is extracted, the stronger the vacuum performance is, and the better the degassing efficiency is. However, the power and energy consumption of the vacuum machine will increase accordingly. After a barrel of raw materials is degassed, the raw materials need to be output. At this time, the outside air will re-enter the equipment. After the next barrel of raw materials is injected into the equipment, the vacuum degassing operation is performed again. This leads to the waste of vacuum effect inside the cavity during the raw material switching process. The vacuum machine needs to repeatedly extract a large amount of gas for degassing operation, which increases energy consumption and production costs. To this end, we propose a raw material degassing device for the production of protective gloves. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. A raw material degassing device for producing protective gloves provided by the present invention solves the problem that a large amount of external gas will enter the interior of the device during the input and output of raw materials in the existing raw material degassing device for producing protective gloves, which greatly increases the energy consumption of vacuuming. The raw material to be degassed is poured into the hopper, and the raw material is output to the corresponding conveying cavity through the output groove. At this time, the lifting ring is at the bottom, and the first pipe on the lifting plate can be connected with the second pipe and the third pipe on the side, so that when 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 surface contacts the bottom surface of the lifting ring, the lifting ring is floated and drives the lifting plate to move up, gradually releasing the connection between the first pipe and the second pipe, and 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 can no longer be input into the conveying cavity, and the feeding operation is completed. In this process, the gas at the top of the raw material is automatically discharged to the outside, which greatly reduces the amount of air inside the chamber during the input process and reduces the energy consumption required for vacuuming.

[0015] 2. A raw material degassing device for producing protective gloves provided by the present invention drives a switching column to rotate and switch by a driving motor until the conveying chamber containing the raw material to be degassed reaches a side close to the vacuum tank. At this time, the fifth pipeline is connected with the sixth pipeline, and at the same time, the driving block slides on the upper sides of the outer ring and the inner ring to above the arc-shaped bottom surface, driving the lifting rod and the lifting frame to move upward, and the lifting plate moves up a distance accordingly, so that a gap is generated between the raw material liquid surface and the lifting plate, so as to avoid directly extracting the raw material when vacuuming. This distance is small, and the driving force required for the lifting plate to move up is also relatively small. During the switching process, the output slot is disconnected from the connecting slot. At this time, the vacuum tank will extract the air on the upper side of the device chamber through the air inlet pipe, and at the same time reduce the air pressure in the conveying chamber. The gas in the conveying chamber flows to the upper side of the lifting plate. At this time, the vacuum pump is started to extract a small amount of air in the vacuum tank, the air inlet pipe and the device chamber, thereby reducing the energy consumption required for vacuuming.

[0016] 3. The present invention provides a raw material degassing device for producing protective gloves. After vacuuming is completed, the driving motor is started again to drive the conveying chamber to rotate to a position connected to the output pipe. At this time, the driving block slides along the arc bottom surface to the lower side of the arc top surface, driving the lifting plate and the lifting ring to move downward, and 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 material is discharged from the output pipe at the bottom, the lifting ring moves downward to connect the first pipeline with the second pipeline, and the external gas can enter the upper side area of ​​the raw material through the fourth pipeline, thereby increasing the speed of raw material output and avoiding the situation that the raw material is difficult to discharge due to air pressure. Thereafter, the empty conveying chamber is rotated to the set position so that the connecting groove is connected to the bottom end of the output groove to perform repeated conveying and degassing operations. Each time the conveying chamber position is switched, the raw materials in different conveying chambers can be respectively input, degassing and output operations are realized, with a high degree of automation, which greatly improves the production efficiency of the protective gloves, and also reduces the energy consumption during vacuuming, making the operation more convenient and efficient.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] The vacuum mechanism 4 also includes a top plate 41 fixedly installed between the fixing ring 17 and the feed hopper 9, and a fifth pipe 42 connected to the air inlet pipe 7 is provided on the top plate 41. A plurality of groups of sixth pipes 43 connected to the top of the device chamber 14 are evenly provided on the fixing column 13. The top surface of the sixth pipe 43 can be connected to the fifth pipe 42. The bottom surface of the top plate 41 is slidably fitted with the bottom surface of the fixing column 13. The lifting rod 36 passes through the top plate 41 and is slidably fitted with the top plate 41.

[0028] In this embodiment, the raw material to be degassed is poured into the hopper 9, and the raw material is output to the corresponding connecting groove 20 through the output groove 19, and finally enters the conveying chamber 3. The driving block 37 here is at the lower side of the arc top surface 40, and the height of the lifting frame 21 is relatively low. At this time, the lifting ring 23 is at the bottom, and the first pipe 30 on the lifting plate 28 can be connected with the second pipe 31 and the third pipe 32 on the side, so that when the raw material is injected into the conveying chamber 3, the air on the upper side can be discharged to the outside through the third pipe 32. As the liquid surface contacts the bottom surface of the lifting ring 23, the lifting ring 23 is floated and drives the lifting plate 28 to move upward, gradually releasing the connection between the first pipe 30 and the second pipe 31, and the lifting plate 28 blocks the bottom end of the second pipe 31 until the lifting ring 23 reaches the top of the lifting groove 22. At this time, the raw material can no longer be input into the conveying chamber 3, and the feeding operation is completed. In this process, the gas at the top of the raw material is automatically discharged to the outside, which greatly reduces the amount of air inside the chamber during the input process and reduces the energy consumption required for vacuuming.

[0029] The switching column 2 is driven to rotate and switch by the driving motor 48 until the conveying chamber 3 containing the raw material to be degassed reaches the side close to the vacuum tank 6. At this time, the fifth pipeline 42 is connected with the sixth pipeline 43, and the driving block 37 slides on the upper side of the outer ring 34 and the inner ring 35 to the top of the arc bottom surface 39, driving the lifting rod 36 and the lifting frame 21 to move up, and the lifting plate 15 moves up a distance, so that a gap is generated between the raw material liquid level and the lifting plate 15 to avoid directly extracting the raw material when vacuuming. This distance is small, and the lifting plate 15 moves up when The required driving force is also relatively small. During the switching process, the output slot 19 is disconnected from the connecting slot 20. At this time, the vacuum tank 6 will extract the air on the upper side of the device chamber 14 through the air inlet pipe 7, and at the same time reduce the air pressure in the conveying chamber 3. The gas in the conveying chamber 3 pushes the sealing ball 47 upward, and flows to the upper side of the lifting plate 15 through the second mounting ring 45 and the first mounting ring 44. At this time, the vacuum pump 5 is started to extract a small amount of air in the vacuum tank 6, the air inlet pipe 7 and the device chamber 14, thereby reducing the energy consumption required for vacuuming.

[0030] After the vacuuming is completed, the driving motor 48 is started again to drive the conveying chamber 3 to rotate to a position connected with the output pipe 10. At this time, the driving block 37 slides along the arc-shaped bottom surface 39 to the lower side of the arc-shaped top surface 40, driving the lifting plate 15 and the lifting ring 23 to move downward, and the fifth pipeline 42 is disconnected from the sixth pipeline 43. At the same time, the second pipeline 31 is connected with the fourth pipeline 33. As the raw material is discharged from the output pipe 10 at the bottom, the lifting ring 23 moves downward to connect the first pipeline 30 with the second pipeline 31. The outside gas can enter the upper area of ​​the raw material through the fourth pipeline 33, thereby increasing the speed of raw material output and avoiding the situation where the raw material is difficult to discharge due to air pressure.

[0031] Thereafter, the empty conveying chamber 3 is rotated to the set position so that the connecting groove 20 is connected to the bottom end of the output groove 19, and the conveying and degassing operation can be repeated. Each time the position of the conveying chamber 3 is switched, the raw materials in different conveying chambers 3 can be input, degassed and output respectively. The high degree of automation greatly improves the production efficiency of the protective gloves, while also reducing the energy consumption during the vacuuming process, making the operation more convenient and efficient.

[0032] It is worth noting that: during the switching of the fixed column 13, when the fifth pipe 42 is not connected to 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 air inlet pipe 7 and the vacuum tank 6 until the next group of sixth pipes 43 are connected to the fifth pipe 42, and a large amount of gas will not enter the vacuum tank 6, ensuring that a large suction intensity will be instantly generated when the fifth pipe 42 is connected to the sixth pipe 43 during each vacuuming process, and only some relatively thin air needs to be extracted later, while the traditional method requires slowly pumping a large amount of internal air into a thin state first. This process is time-consuming and greatly reduces the production efficiency. Sealing rings can be set at both ends of all pipes of the device as needed, and it is necessary to regularly check the sealing of the connection between the two ends of the pipe when the conveying chamber is switched to avoid gas and liquid overflow.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
