Description

Technical Field

[0001] This application relates to the field of raw material extraction equipment technology, and in particular to a device for extracting multiple raw materials for latex products. Background Technology

[0002] The aqueous dispersion system of rubber microparticles is usually called latex. Latex can be used directly as a surface coating, to manufacture films and adhesives, etc. After processing, it can be made into latex products such as sponges, gloves, balloons, condoms, medical tubing, etc. Latex products are widely used in daily life.

[0003] The production of latex products requires the addition of various liquid raw materials. Currently, water pumps are commonly used in conjunction with pipelines to directly extract these liquid raw materials. While water pumps can effectively extract the raw materials, the fact that most latex raw materials are quite viscous and highly adhesive means that material residue can easily remain inside the pump during use. This not only leads to waste but also causes blockages, affecting extraction efficiency. Utility Model Content

[0004] To address the problem of material residue easily remaining inside water pumps, which not only leads to waste but also causes blockages and affects extraction efficiency, this application provides a device for extracting multiple raw materials from latex products.

[0005] The technical solution of the latex product multiple raw material extraction device provided in this application is as follows:

[0006] A device for extracting multiple raw materials for latex products includes a frame and a mixing cylinder, a storage cylinder, and an air pump mounted on the frame. The mixing cylinder has a discharge pipe at its bottom and a cover plate at its top. The cover plate has a receiving hopper at its bottom, and a drop pipe is vertically arranged at the bottom of the receiving hopper. The cover plate has multiple feed pipes communicating with the inner cavity of the receiving hopper. Each feed pipe is connected to the bottom of a storage cylinder through a pipe, and each feed pipe is equipped with a first switching valve. An air extraction pipe is provided on the top side wall of the mixing cylinder, and the air inlet of the air pump is connected to the air extraction pipe.

[0007] By adopting the above technical solution, a negative pressure is created by drawing air from the mixing drum using an air pump. This allows the raw materials in the storage drum to enter the mixing drum through the feed pipe, receiving hopper, and discharge pipe. The discharge pipe can then discharge the mixed raw materials. This enables the extraction of multiple raw materials for latex products, facilitating the production of latex products. Furthermore, the raw materials for latex products do not pass through the pump body during the extraction process, eliminating the problem of material waste or blockage caused by residual material in the pump body. This improves upon the issue of material residue in water pumps, which not only leads to waste but also easily causes blockages, affecting extraction efficiency.

[0008] Optionally, the cover plate has an insertion hole directly above the discharge pipe, and the top of the cover plate has a linear drive component vertically arranged. The output end of the linear drive component passes through the insertion hole, and a scraper is provided on the output end of the linear drive component. The diameter of the scraper is adapted to the inner diameter of the discharge pipe.

[0009] By adopting the above technical solution, when it is necessary to clean the discharge pipe, the linear drive unit is activated, and its output end moves vertically along the insertion hole, driving the scraper to move vertically inside the discharge pipe. Since the diameter of the scraper is matched with the inner diameter of the discharge pipe, it can effectively clean the inner wall of the discharge pipe, reduce the waste caused by raw material adhesion, and reduce the probability of blockage.

[0010] Optionally, a sealing gasket is provided on the top of the scraper.

[0011] By adopting the above technical solution, the setting of the sealing gasket enables the scraper to better seal the insertion hole when it rises to abut against the cover plate, ensuring a negative pressure environment inside the mixing cylinder and reducing the energy consumption of the air pump.

[0012] Optionally, the bottom wall of the mixing drum is provided with multiple weight sensors, and the weight sensors are provided with inner liner cylinders. The outer diameter of the inner liner cylinder is adapted to the inner diameter of the mixing drum. The bottom of the inner liner cylinder is provided with a discharge pipe, which passes through the discharge pipe. The discharge pipe is provided with a second switch valve, and a sealing ring is provided between the discharge pipe and the discharge pipe.

[0013] By adopting the above technical solution, the weight sensor can monitor the weight of the raw material in the inner liner in real time, which facilitates the control of the raw material quantity; the matching of the outer diameter of the inner liner with the inner diameter of the mixing cylinder can make the inner liner stably set in the mixing cylinder; the discharge pipe is inserted into the discharge pipe, and a second switch valve is provided on the discharge pipe to facilitate the control of raw material discharge; a sealing ring is provided between the discharge pipe and the discharge pipe to prevent raw material leakage.

[0014] Optionally, the inner wall of the top of the inner liner is provided with an internal gear ring, the top of the inner liner is provided with a horizontal cover, the middle of the horizontal cover is rotatably connected to a first gear around the axis of the inner liner, the bottom of the horizontal cover is provided with an annular groove, a stirring rod is slidably engaged in the annular groove, the top of the stirring rod is provided with a second gear, the second gear meshes with the first gear and the internal gear ring, the stirring rod is provided with stirring blades, and the horizontal cover is provided with a drive assembly for driving the first gear to rotate.

[0015] By adopting the above technical solution, the drive component drives the first gear to rotate. Since the second gear meshes with the first gear and the internal gear ring, the second gear rotates while making circumferential motion along the internal gear ring, thereby driving the stirring blades on the stirring rod to rotate as well, realizing the stirring and mixing of various raw materials in the inner liner and improving the uniformity of the raw material mixing.

[0016] Optionally, the drive assembly includes a rotary motor, a driving bevel gear, and a driven bevel gear. The rotary motor is mounted on the horizontal cover, the driving bevel gear is mounted on the rotating shaft of the rotary motor, the driven bevel gear is coaxially connected to the first gear, and the driven bevel gear meshes with the driving bevel gear.

[0017] By adopting the above technical solution, after the rotating motor starts, its rotating shaft drives the active bevel gear to rotate, the active bevel gear drives the driven bevel gear that meshes with it to rotate, the driven bevel gear drives the first gear that is coaxially connected with it to rotate, and the first gear drives the stirring rod to slide and rotate in the annular groove through the meshing relationship with the second gear, thereby making the stirring blades stir the raw materials in the inner liner and achieve full mixing of the raw materials.

[0018] Optionally, a level gauge is provided on the top side wall of the inner liner.

[0019] By adopting the above technical solution, the liquid level in the inner liner can be monitored in real time using a level gauge, which makes it easier for staff to understand the amount of raw materials in a timely manner and avoid overflow or shortage.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. By using an air pump to draw air out of the mixing drum to create negative pressure, the raw materials in the storage drum enter the mixing drum through the feed pipe, receiving hopper and discharge pipe. This enables the extraction of various raw materials for latex products. The raw materials for latex products do not pass through the pump body during the extraction process, eliminating the problem of raw material waste or blockage caused by residual raw materials in the pump body. This improves the problem that water pumps are prone to raw material residue, which not only causes waste but also blockage and affects extraction efficiency.

[0022] 2. The matching arrangement of the linear drive component and the scraper can clean the inner wall of the feed pipe, reduce material adhesion and waste, and reduce the probability of blockage.

[0023] 3. The matching arrangement of the internal gear ring, stirring rod, first gear, second gear and drive assembly enables the drive assembly to drive the first gear to rotate, which in turn drives the second gear to rotate along the internal gear ring in a circular motion while rotating on its own axis. This, in turn, drives the stirring blades on the stirring rod to rotate, thereby stirring and mixing the various raw materials in the inner liner and improving the uniformity of the raw material mixture.

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a device for extracting multiple raw materials from latex products. (Refer to...) Figure 1-2 The latex product extraction device includes a frame 1 and a mixing cylinder 2, a storage cylinder 3, and an air pump 4 mounted on the frame 1. The bottom of the mixing cylinder 2 is connected to a discharge pipe 21. An inner liner 5 is installed inside the mixing cylinder 2, with its outer diameter matching the inner diameter of the mixing cylinder 2 in a clearance fit. Multiple weight sensors 6 are installed between the bottom wall of the inner liner 5 and the bottom wall of the mixing cylinder 2 to monitor the weight of the material inside the inner liner 5 in real time. The weight sensors 6 are generally strain gauge weight sensors, which convert weight signals into electrical signals; piezoresistive weight sensors can also be used. The bottom of the inner liner 5 is connected to a discharge pipe 51, which passes through the discharge pipe 21. A sealing ring 52, which is an O-ring, is installed between the discharge pipe 51 and the discharge pipe 21. A second switching valve 53 is installed on the discharge pipe 51. A stirring mechanism 7 for stirring the material is installed inside the inner liner 5.

[0031] A cover plate 22 is fitted over the top of the mixing drum 2, serving to seal the mixing drum 2. A receiving hopper 23 is fixedly connected to the bottom of the cover plate 22, and a discharge pipe 24 is connected through the bottom of the receiving hopper 23, with the bottom of the discharge pipe 24 close to the bottom of the inner liner 5. Storage cylinders 3 are mounted on the frame 1 above the mixing drum 2. Multiple storage cylinders 3 are provided for storing different raw materials. Multiple feed pipes 25, communicating with the inner cavity of the receiving hopper 23, are connected to the top of the cover plate 22. Each feed pipe 25 is connected to the bottom of a storage cylinder 3 through a pipe, and each feed pipe 25 is equipped with a first switching valve 26. An air extraction pipe 27 is connected to the top side wall of the mixing drum 2, and the air inlet of the air pump 4 is connected to the air extraction pipe 27.

[0032] When raw materials need to be extracted, the first switch valve 26 on the feed pipe 25 connected to the corresponding storage cylinder 3 is opened, and the air pump 4 is started to draw air from the mixing cylinder 2 to create negative pressure. Under the action of external atmospheric pressure, the material in the corresponding storage cylinder 3 is drawn into the receiving hopper 23. The material then enters the inner liner cylinder 5 through the receiving hopper 23 and the discharge pipe 24. At this time, the weight sensor 6 monitors the weight of the material in the inner liner cylinder 5 in real time, improving the accuracy of raw material extraction. After the raw materials are extracted, the stirring mechanism 7 stirs the different raw materials to improve the mixing uniformity. Finally, the second switch valve 53 is opened to allow the mixed raw materials to be discharged through the discharge pipe 51. The raw materials for latex products do not pass through the pump body during the extraction process, eliminating the problem of raw material waste or blockage caused by residual raw materials in the pump body. This improves the problem that raw material residue is easy to remain in the water pump, which not only causes waste but also easily causes blockage and affects the extraction efficiency.

[0033] Furthermore, refer to Figure 2 To reduce the probability of blockage in the material discharge pipe 24 during raw material extraction, an insertion hole is provided on the cover plate 22 directly above the material discharge pipe 24. A linear drive component 8 is vertically mounted on the top of the cover plate 22. The linear drive component 8 is an electric telescopic rod, with its telescopic end inserted into the insertion hole. A scraper block 81 is fixedly connected to the telescopic end, and the diameter of the scraper block 81 is the same as the inner diameter of the material discharge pipe 24. When the linear drive component 8 is activated, the scraper block 81 moves vertically within the material discharge pipe 24. Since the diameter of the scraper block 81 matches the inner diameter of the material discharge pipe 24, it can effectively clean the inner wall of the material discharge pipe 24, reducing material adhesion and waste, and reducing the probability of blockage. In addition, a sealing gasket 82 is provided on the top of the scraper block 81. When cleaning of the material discharge pipe 24 is not required, the scraper block 81 rises until the top sealing gasket 82 abuts against the bottom wall of the cover plate 22, thereby better sealing the insertion hole, ensuring a negative pressure environment within the mixing cylinder 2, and reducing the energy consumption of the air pump 4.

[0034] For example, refer to Figure 2 and Figure 3The stirring mechanism 7 includes a stirring rod 71, an internal gear ring 72, a first gear 73, a second gear 74, and a drive assembly. A horizontal cover 54 is provided at the top of the inner liner 5. The first gear 73 is rotatably connected to the middle of the horizontal cover 54 around the axis of the inner liner 5. An annular groove 55 is provided at the bottom of the horizontal cover 54, with its central axis coinciding with the axis of the inner liner 5. The interface of the annular groove 55 is inverted T-shaped. A limiting disc is integrally formed at the top of the stirring rod 71, and the limiting disc is slidably engaged within the annular groove 55. Stirring blades are provided on the stirring rod 71. The second gear 74 is coaxially connected to the upper part of the stirring rod 71, and the internal gear ring 72 is coaxially connected to the inner circumferential wall of the inner liner 5 below the horizontal cover 54. The second gear 74 meshes with both the internal gear ring 72 and the first gear 73. The drive assembly is located on the horizontal cover 54 and is used to drive the first gear 73 to rotate.

[0035] The drive assembly drives the first gear 73 to rotate. The first gear 73 meshes with the second gear 74, causing the stirring rod 71 to slide in the annular groove 55. At the same time, due to the meshing of the second gear 74 with the inner gear ring 72, the stirring rod 71 will revolve around the axis of the inner liner 5 while rotating on its own axis. The stirring blades will rotate accordingly, so as to fully stir the raw materials in the inner liner 5 in all directions without dead angles, thereby improving the mixing uniformity of the raw materials.

[0036] Specifically, the drive assembly includes a rotary motor 75, a driving bevel gear 76, and a driven bevel gear 77. The rotary motor 75 is bolted to the cross cover 54. The driving bevel gear 76 is coaxially connected to the rotating shaft of the rotary motor 75. The driven bevel gear 77 is coaxially connected to the first gear 73 and meshes with the driving bevel gear 76. A protective cover 78 is provided on both the driving bevel gear 76 and the driven bevel gear 77. The rotary motor 75 is generally an AC motor or a DC motor, but a stepper motor can also be used, which can precisely control the speed and direction of rotation. When the rotary motor 75 is working, it drives the driving bevel gear 76 to rotate. The driving bevel gear 76, through meshing with the driven bevel gear 77, transmits power to the first gear 73, thereby driving the stirring rod 71 and the stirring blades to rotate. The transmission efficiency is high and the transmission is stable.

[0037] In addition, refer to Figure 2 A level gauge 56 is also installed on the top side wall of the inner liner 5 to monitor the liquid level of the raw material inside the inner liner 5 in real time. It can be a float-type level gauge 56, indicating the liquid level by the up-and-down movement of a float, or an ultrasonic level gauge 56, measuring the liquid level using the principle of ultrasonic wave reflection. The level gauge 56 is connected to the top side wall of the inner liner 5 via threads or flanges, accurately measuring the liquid level of the raw material inside the inner liner 5. This allows operators to promptly understand the status of the raw material and prevent overflow or shortage.

[0038] The implementation principle of this embodiment is as follows: The latex product multiple raw material extraction device creates negative pressure in the mixing cylinder 2 through the air pump 4. This negative pressure draws multiple raw materials from the storage cylinder 3 into the inner liner 5 of the mixing cylinder 2 through the feed pipe 25, receiving hopper 23, and discharge pipe 24. The weight sensor 6 monitors the weight of the raw materials in the inner liner 5 in real time, enabling precise control of the raw material ratio. The stirring mechanism 7 drives the stirring rod 71 and stirring blades to rotate via the drive assembly, thoroughly stirring the raw materials from all directions to improve mixing uniformity. The level gauge 56 monitors the liquid level in the inner liner 5 in real time. Furthermore, the linear drive 8 drives the scraper 81 to clean the inner wall of the discharge pipe 24, and the sealing gasket 82 enhances the sealing effect. Compared with existing technologies, this device can efficiently and accurately extract and mix a variety of raw materials, avoiding errors caused by manual weighing and adding of raw materials. Moreover, the raw materials for latex products do not pass through the pump body during the extraction process, eliminating the problem of raw material waste or blockage caused by residual raw materials in the pump body. This improves the problem that raw material residue is easy to exist in the water pump, which not only causes waste but also easily causes blockage and affects extraction efficiency.

[0039] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
