Description

Technical Field

[0001] This application relates to the technical field of rubber mixing devices, and in particular to an automatic feeding device for a rubber mixing device. Background Art

[0002] Rubber is a product of molecular technology and is widely used in various fields. Rubber is generally prepared using a rubber compounding process. By appropriate processing, the compounding agents are uniformly mixed with the raw rubber to form a homogeneous mixture, and then various additives are added to the mixture and mixed evenly, and then mixed evenly using a mixing device to complete the preparation.

[0003] Before mixing the rubber material, it is generally necessary to pre-mix the rubber raw material and the additive raw material, and then use the mixing device to repeatedly extrude the rubber material until the rubber material meets the production requirements of the product. However, since the additive raw material is composed of multiple raw materials, it is necessary to continuously add the additive raw material manually when mixing with the additive to ensure uniform mixing. Since the rubber raw material is a relatively viscous liquid, if the feeding is uneven, then during subsequent mixing and processing, it will require a long time of stirring, affecting the production efficiency. Utility Model Content

[0004] The purpose of this application is to provide an automatic feeding device for a rubber mixing device to solve the problems raised in the above background art.

[0005] Specifically, this application adopts the following technical solutions to achieve the above purpose:

[0006] An automatic feeding device for a rubber mixing device includes a mounting base plate. A feeding device housing is welded in the middle on the upper side of the mounting base plate. A driving housing is welded on one side of the feeding device housing. A batching box is welded in the middle on the upper side of the feeding device housing. A sieve device is welded in the middle of the batching box. An inlet is welded on the upper end of the feeding device housing near one side of the driving housing. A pair of first stepping motors are fixedly installed on the side wall of the driving housing far from the feeding device housing. The output ends of the paired first stepping motors are both fixedly installed with driving rollers. Stirring fan blades are helically welded on the outside of the driving rollers. An elastic device is arranged on the lower side of the feeding device housing. An extrusion discharging device is arranged below the side of the feeding device housing far from the driving housing.

[0007] By adopting the above technical solutions, when the additives to be mixed are filled above the sieve device of this device, during the stirring and transportation of the raw materials below, the additives can be evenly mixed into the raw materials below under the vibration screening of the sieve device, improving the quality of rubber production, reducing the subsequent mixing time, and increasing the production efficiency.

[0008] Furthermore, support brackets are welded and installed on both the left and right sides of the mounting base plate away from the drive housing.

[0009] By adopting the above technical solution, the provided universal wheels can facilitate the operator to move the device, thus facilitating the connection with the mixing device.

[0010] Furthermore, a cover body is rotatably installed on the upper side of the batching box through a hinge.

[0011] By adopting the above technical solution, it is convenient to add auxiliary raw materials. After the addition is completed, the cover body can be closed to reduce the flying of dust.

[0012] Furthermore, the screening device includes a pair of support plates fixedly installed on the inner wall of the middle part of the sliding slope. A support frame is arranged on the upper side of the support plate, a metal screen plate is arranged in the middle of the support frame, several springs are fixedly installed vertically between the support frame and the support plate, a pair of first spring bases are fixedly installed on the upper end of the support plate on the side of the spring, and corresponding first spring protection plates are fixedly installed on the outer side of the first spring bases on the lower side of the support frame. A high-frequency vibrator is fixed on the support frame.

[0013] By adopting the above technical solution, the first spring bases and the springs can prevent the raw materials on the outside from contacting the springs, so that the internal springs can always play their roles. The high-frequency vibrator can drive the overall vibration of the support frame, and can make the added raw materials inside leak evenly from the position of the metal screen plate.

[0014] Furthermore, sliding slopes are welded and fixed on the inner side walls of both sides of the feeding port.

[0015] By adopting the above technical solution, it is ensured that the materials can smoothly fall from the feeding port, thus facilitating the subsequent stirring process.

[0016] Furthermore, the elastic device includes a pair of second spring protection plates fixedly installed on the inner bottom wall of the feeding device housing. A support spring is arranged on the inner wall of the middle part of the feeding device housing where the second spring protection plates are located. A protection partition is fixedly installed on the upper side of the support spring. Second spring bottom plates corresponding to the second spring protection plates are fixedly installed at the positions of the second spring protection plates on the lower side of the protection partition. The size of the second spring bottom plates is smaller than that of the second spring protection plates, and the second spring protection plates and the second spring bottom plates are nested with each other.

[0018] Furthermore, protective backing plates are fixedly installed on both sides of the elastic device on the inner bottom wall of the feeding device housing, and the protective backing plates are made of rubber material.

[0019] By adopting the above technical solution, if there is too much filler inside the feeding device housing, it can play a certain supporting and protecting role for the protective partition.

[0021] By adopting the above technical solution, when the internal raw materials are pushed to the position of the driving extrusion rod, since the driving extrusion rod rotates downward, the raw materials can be smoothly discharged downward through the extrusion of the driving extrusion rod and the driven extrusion rod.

[0022] In summary, the present application includes at least one of the following beneficial effects;

[0023] 1. In the present application, by providing a sieve device, additives to be mixed are filled above the sieve device, and when the raw materials below are being stirred and transported, the additives can be evenly mixed into the raw materials below under the vibration screening of the sieve device, improving the quality of rubber production, reducing the subsequent mixing time, and increasing the production efficiency.

[0032] The following is a further detailed description of the present application in conjunction with the attached Figures 1-5 drawings.

[0033] An automatic feeding device of a rubber mixing device is disclosed in an embodiment of the present application.

[0034] Referring to Figure 1 and Figure 2 , an automatic feeding device of a rubber mixing device includes an installation base plate 2. A feed device housing 3 is welded and installed in the middle of the upper side of the installation base plate 2. A drive housing 7 is welded and installed on one side of the feed device housing 3. A batching box 4 is welded and installed on the upper middle part of the feed device housing 3. A screening and leakage device is welded and installed in the middle of the batching box 4. An inlet 6 is welded and installed on one side of the upper end of the feed device housing 3 close to the drive housing 7. Slide slopes 10 are welded and fixed on the inner side walls of the sides of the inlet 6 to ensure that the material can fall from the inlet 6 smoothly, thus facilitating subsequent stirring and processing. A pair of first stepping motors 13 are fixedly installed on the side wall of the drive housing 7 away from the feed device housing 3. The output ends of the paired first stepping motors 13 are fixedly installed with drive rollers 9. One end of the drive roller 9 penetrates through the feed device housing 3, and bearings corresponding to the drive roller 9 are provided on the inner wall of the feed device housing 3 away from the drive housing 7 to ensure the stable operation of the drive roller 9 during rotation. Stirring fan blades 901 are helically welded on the outside of the drive roller 9. An elastic device is provided on the lower side of the feed device housing 3. Protection backing plates 14 are fixedly installed on both sides of the elastic device on the inner bottom wall of the feed device housing 3. The protection backing plates 14 are rubber material components. If there is too much filler inside the feed device housing 3, it can play a certain role in supporting and protecting the protection partition 15. An extrusion and discharging device is provided below one side of the feed device housing 3 away from the drive housing 7, and a square groove is opened on the bottom wall of the feed device housing 3 at the position of the extrusion and discharging device to facilitate discharging.

[0035] By adopting the above technical solution, additives to be mixed are filled above the sieving device. When the raw materials below are being stirred and transported, the additives can be evenly mixed into the raw materials below under the vibration sieving of the sieving device, improving the quality of rubber production, reducing the subsequent mixing time, and increasing the production efficiency.

[0036] Referring to Figure 1 , support brackets 1 are welded on both the left and right sides of the mounting base plate 2 away from the drive housing 7. Universal wheels are provided at the lower ends of the support brackets 1. A sliding plate 8 is fixedly installed on one side of the lower end of the mounting base plate 2 away from the drive housing 7. The top of the extrusion discharging device corresponds to the extrusion discharging. The material will fall from the extrusion discharging into the sliding plate 8 and can enter the subsequent mixing device along the sliding plate 8.

[0037] Referring to Figure 1 and Figure 2 , a cover body 5 is rotatably installed on the upper side of the batching box 4 through a hinge.

[0038] By adopting the above technical solution, it is convenient to add auxiliary raw materials. After the addition is completed, the cover body 5 can be closed, thus reducing the flying of dust.

[0039] Referring to Figure 2 and Figure 3 , the sieving device includes a pair of support plates 17 fixedly installed on the inner wall of the middle part of the sliding slope 10. A support frame 11 is arranged on the upper side of the support plate 17. A metal screen plate 12 is arranged in the middle of the support frame 11. The size of the metal screen plate 12 is selected according to the selected catalyst raw materials. Since the catalyst raw materials are composed of a variety of substances, the catalyst raw materials will gradually fall with the vibration of the metal screen plate 12, so as to be evenly mixed with the rubber raw materials below. A number of springs 23 are fixedly installed vertically between the support frame 11 and the support plate 17. A pair of first spring bases 16 are fixedly installed on the side of the upper end of the support plate 17 beside the springs 23. Corresponding first spring protection plates 18 are fixedly installed on the outside of the first spring bases 16 at the lower side of the support frame 11. A high-frequency vibrator 19 is fixed on the support frame 11. The side of the first spring protection plate 18 is slightly larger than that of the first spring base 16. The first spring protection plate 18 and the first spring base 16 are nested and connected, which can play a certain protective role for the internal spring 23 and prevent foreign objects from entering the inside of the spring 23. Both the first spring protection plate 18 and the first spring base 16 are made of soft rubber material and will not hinder the vibration of the support frame 11.

[0040] By adopting the above technical solution, the first spring base 16 and the spring 23 can prevent the raw materials outside from contacting the spring 23, so that the internal spring 23 can always play its role. The high-frequency vibrator 19 can drive the overall vibration of the support frame 11, enabling the raw materials added inside to leak evenly from the position of the metal screen plate 12.

[0041] Reference Figure 4 , the elastic device includes a pair of second spring protection plates 21 fixedly installed on the inner bottom wall of the feeding device housing 3. A support spring 22 is arranged on the inner wall of the feeding device housing 3 in the middle of the second spring protection plate 21. A protection partition 15 is fixedly installed on the upper side of the support spring 22. A second spring bottom plate 20 corresponding to the second spring protection plate 21 is fixedly installed at the position of the second spring protection plate 21 on the lower side of the protection partition 15. The size of the second spring bottom plate 20 is smaller than that of the second spring protection plate 21, and the second spring protection plate 21 and the second spring bottom plate 20 are nested with each other.

[0042] By adopting the above technical solution, the elastic device will compress the internal support spring 22 under force, keeping the internal raw materials in a dynamic balance state, so that when the raw materials are stirred, they are always closely attached to the side, thus making the stirring more sufficient.

[0043] Reference Figure 1 and Figure 5 , the extrusion discharging device includes a second stepping motor 26 fixedly installed at the rear of the feeding device housing 3 away from the driving housing 7. The output end of the second stepping motor 26 is fixedly installed with a driving extrusion rod 25. A driven extrusion rod 24 is rotatably installed on the mounting base plate 2 on one side of the feeding device housing 3 where the driving extrusion rod 25 is located. Bearings corresponding to the driving extrusion rod 25 and the driven extrusion rod 24 are arranged on the front and rear side walls of the feeding device housing 3. Tooth grooves that mesh with each other are arranged on the outer sides of the driven extrusion rod 24 and the driving extrusion rod 25.

[0044] By adopting the above technical solution, when the internal raw materials are pushed to the position of the driving extrusion rod 25, since the driving extrusion rod 25 rotates downward, the raw materials can be smoothly discharged downward through the extrusion of the driving extrusion rod 25 and the driven extrusion rod 24.

[0045] Working principle: The operator connects the discharge end of the sliding material plate 8 of the present utility model to the mixing device, places the rubber material raw material through the feeding port 6, starts the first stepping motor 13, and the first stepping motor 13 drives the stirring fan blade 901 to rotate through the driving roller 9, so that the rubber raw material can be transported towards the extrusion discharge device. Open the cover body 5, fill the mixed catalyst raw material inside the cover body 5, and start the high-frequency vibrator 19 in the sieve leakage device. At this time, since the support frame 11 is arranged on the support plate 17 through the spring 23, when the high-frequency vibrator 19 starts, the entire support frame 11 generates high-frequency vibration, and the vibration will loosen the catalyst raw material and evenly sprinkle it downward from the position of the metal sieve plate 12 in the middle on the rubber raw material, improving the quality of rubber production, reducing the subsequent mixing time, increasing the production efficiency, and during the process of mixing and conveying with the stirring fan blade 901, the elastic device below will cause the support spring 22 to be compressed due to the extrusion of the upper rubber raw material. At this time, the internal rubber raw material and the elastic device are in dynamic balance, and the rubber raw material is always under extrusion, so that the additive raw material and the material are mixed and stirred more fully. When the rubber mixture is transported to the extrusion discharge device position, the second stepping motor 26 drives the driving extrusion rod 25 to rotate, so as to extrude and discharge the rubber mixture from the position of the sliding material plate 8, completing the preliminary mixing and automatic discharging of the material, which is convenient for subsequent processing.
