Description
Technical Field
[0001] This utility model relates to the field of rubber processing technology, specifically a rubber processing batching device. Background Technology
[0002] In the production process of gaskets, rubber is required as the main raw material. However, the basic properties of rubber itself are limited. Therefore, it is necessary to add a variety of additives to form a multi-component synergistic system to improve the performance of rubber and thus improve the performance of the gasket. This requires a batching device.
[0003] A Chinese patent with authorization announcement number CN220129192U discloses a batching device for rubber processing, including a storage bin. The bottom of the storage bin is connected to the interior of the batching bin via a feeding pipe. The top of the storage bin is equipped with a feeding pipe and a first motor. This invention controls the operation of the motor through a first control panel, thereby controlling the amount of material added to the batching bin below. While an appropriate amount of material is added to the batching bin, a second control panel controls a second motor to drive a stirring shaft connected to it to rotate, which can fully mix the two materials together. After the two different materials are completely mixed, the valve is opened through the second control panel, and the mixture is injected into the mixing device through the discharge pipe below the batching bin. The second mixer can ensure the mixing effect of the materials, and the setting of the feeding shaft avoids material accumulation.
[0004] However, the above-mentioned device still has some problems. In practical applications, when solid raw materials enter the batching cylinder, they will naturally accumulate and form a loose, hill-like structure with a large number of gaps between the raw materials, resulting in an apparent volume that is larger than the actual compacted volume, which will cause deviations in the batching amount. Therefore, a batching device for rubber processing is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a batching device for rubber processing.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A rubber processing batching device of this utility model includes a support frame. A rotating shaft is rotatably mounted on the inner wall of the bottom side of the support frame. A mixing tank is mounted on the top side of the rotating shaft. Three fixed frames are equidistantly mounted on the top edge of the mixing tank. A sleeve is mounted on one side of each fixed frame. A movable rod is slidably mounted on one end of the sleeve. A limit block is mounted on one end of the movable rod. A tension spring is fixedly connected between the limit block and the sleeve. The tension spring is sleeved on the outside of the movable rod. The other end of each movable rod slides through the interior of the fixed frame and is equipped with a batching device. The mixing cylinder is made of transparent material, and several scale lines are equidistantly engraved on its outer side. A flexible hose is connected to the bottom of the mixing cylinder, and all the hoses are connected to the mixing tank. A drive motor is mounted on the top side of the support frame, and a rotating shaft is mounted on the output end of the drive motor. A cam is mounted on the top of the rotating shaft. During operation, the cam contacts the outer side of the mixing cylinder. Starting the drive motor causes the rotating shaft and cam to rotate, and the contact between the cam and the mixing cylinder generates vibration, causing the solid raw materials to spread evenly inside the mixing cylinder, further reducing mixing errors. Furthermore, the vibration of the mixing cylinder during feeding reduces the occurrence of blockages.
[0007] Preferably, a servo motor is connected to one side of the bottom end of the mixing cylinder, and a connecting shaft is installed at the output end of the servo motor. A baffle is installed on the outside of the connecting shaft inside the mixing cylinder. The radius of the baffle is less than or equal to the inner diameter of the bottom end of the mixing cylinder. The servo motor drives the connecting shaft to rotate, so that the baffle is perpendicular to the mixing cylinder, opening the discharge channel and allowing the solid raw materials to enter the mixing tank through the hose.
[0008] Preferably, a gear ring is installed on the outer bottom of the mixing barrel, a main drive gear is installed on the top of the rotating shaft, a support shaft is rotatably installed on the bottom side of one end of the support frame, a driven gear is installed on the top of the support shaft, the main drive gear and the driven gear are connected by a toothed belt, and a circular gear is installed on the bottom side of the support shaft, and the circular gear meshes with the gear ring. When the rotating shaft rotates, the mixing barrel rotates in the opposite direction to the rotating shaft through the transmission of the main drive gear, the driven gear, the toothed belt and the circular gear, thereby enhancing the mixing effect.
[0009] Preferably, one end of the rotating shaft extends through the mixing tank and reaches its bottom. Two scrapers are symmetrically installed on the outer side of the rotating shaft, and the scrapers are in contact with the inner wall of the mixing tank. Four sets of three stirring blades are equidistantly installed on the outer side of the rotating shaft. The scrapers are in contact with the inner wall of the mixing tank and can scrape off the raw materials adhering to the inner wall. At the same time, during the rotation of the mixing tank and the rotating shaft, the stirring blades fully stir the raw materials, improving the mixing efficiency.
[0010] Preferably, a discharge pipe is connected to one side of the bottom of the mixing tank, and a discharge valve is installed inside the discharge pipe to control the discharge of the mixed raw materials.
[0011] Preferably, a control panel is installed on one side of the support frame. The control panel is electrically connected to the electrical components inside the device and is used to control the operation of the electrical components inside the device, thereby realizing centralized control of the electrical components inside the device.
[0012] The advantages of this utility model are:
[0013] 1. This utility model uses a drive motor to rotate a rotating shaft, which in turn rotates a cam. When the cam presses against the dispensing cylinder, the dispensing cylinder causes the movable rod to slide within the sleeve, stretching the tension spring. As the cam continues to rotate, the pressure exerted by the cam on the dispensing cylinder disappears, the tension spring returns to its original state, and the dispensing cylinder is pulled back to its initial position. This cycle repeats, causing the dispensing cylinder to vibrate. This causes the solid raw materials poured into the dispensing cylinder to spread out evenly under the combined action of gravity and vibration. The amount of raw materials can be read more accurately through the scale lines, reducing dispensing errors. At the same time, the vibration of the dispensing cylinder during feeding can also reduce the phenomenon of blockage during feeding.
[0014] 2. When the rotating shaft of this utility model rotates, the main drive gear rotates accordingly. The main drive gear drives the driven gear to rotate through the toothed belt, thereby causing the support shaft and the circular gear to rotate as well. Since the circular gear meshes with the gear ring, the rotation of the circular gear drives the mixing barrel to rotate in the opposite direction to the rotating shaft. At the same time, during the rotation of the rotating shaft, the scraper can scrape off the raw materials adhering to the inner wall of the mixing barrel. The stirring blades also rotate, and the mixing barrel also rotates in the opposite direction. The stirring blades can fully stir the raw materials, enhance the mixing effect, and improve the mixing efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] Please see Figure 1-4 As shown, a rubber processing batching device includes a support frame 1. A rotating shaft 2 is rotatably mounted on the bottom inner wall of the support frame 1. A mixing tank 3 is mounted on the top side of the rotating shaft 2. Three fixed brackets 4 are equidistantly mounted on the top edge of the mixing tank 3. A sleeve 5 is mounted on one side of each fixed bracket 4. A movable rod 6 is slidably mounted on one end of the sleeve 5. A limit block 7 is mounted on one end of the movable rod 6. A tension spring 8 is fixedly connected between the limit block 7 and the sleeve 5. The tension spring 8 is sleeved on the outside of the movable rod 6. The other end of the moving rod 6 slides through the inside of the fixed frame 4 and is equipped with a dispensing cylinder 9. The dispensing cylinder 9 is made of transparent material. Several scale lines 10 are equidistantly engraved on the outer side of the dispensing cylinder 9. A flexible hose 11 is connected to the bottom side of the dispensing cylinder 9. The flexible hose 11 is connected to the mixing tank 3. A drive motor 12 is installed on the top side of the support frame 1. A rotating shaft 13 is installed at the output end of the drive motor 12. A cam 14 is installed at the top of the rotating shaft 13. The cam 14 will contact the outer side of the dispensing cylinder 9 during operation.
[0024] A servo motor 15 is connected to one side of the bottom of the mixing cylinder 9. A connecting shaft 16 is installed at the output end of the servo motor 15. A baffle 17 is installed inside the mixing cylinder 9 on the outer side of the connecting shaft 16. The radius of the baffle 17 is less than or equal to the inner diameter of the bottom of the mixing cylinder 9. A control panel 28 is installed on one side of the support frame 1. During operation, in practical applications, solid raw materials will naturally accumulate when entering the mixing cylinder 9, forming a loose, hill-like structure with a large number of gaps between the raw materials. This results in an apparent volume larger than the actual compacted volume, causing deviations in the mixing quantity. Before mixing begins, the baffle 17 is in a horizontal position, blocking the outlet of the mixing cylinder 9 to prevent the raw materials from falling prematurely. Then, the solid raw materials are poured into the mixing cylinder 9, and the drive motor 12 is started. The output of the drive motor 12... The output end drives the rotating shaft 13 to rotate, and the cam 14 at the top of the rotating shaft 13 rotates accordingly. When the cam 14 is working, it will contact the outer side of the dispensing cylinder 9. When the cam 14 squeezes the dispensing cylinder 9, the dispensing cylinder 9 drives the movable rod 6 to slide in the sleeve 5, and the tension spring 8 is stretched. As the cam 14 continues to rotate, the squeezing force of the cam 14 on the dispensing cylinder 9 disappears, the tension spring 8 returns to its original state, and pulls the dispensing cylinder 9 back to the initial position. This cycle repeats, and the dispensing cylinder 9 vibrates, so that the solid raw materials poured into the dispensing cylinder 9 are spread out under the combined action of gravity and vibration, avoiding the solid raw materials from piling up into small hills. The operator can read the amount of raw materials more accurately through the scale line 10 on the outer side of the dispensing cylinder 9, reducing dispensing errors. At the same time, the vibration of the dispensing cylinder 9 can also reduce the phenomenon of blockage during feeding.
[0025] When the amount of raw material in the batching cylinder 9 reaches the required value, the servo motor 15 is started through the control panel 28. The output end of the servo motor 15 drives the connecting shaft 16 to rotate. The baffle 17 located inside the batching cylinder 9 on the outside of the connecting shaft 16 rotates accordingly. When the baffle 17 rotates to be perpendicular to the batching cylinder 9, the discharge channel is opened, and the solid raw material in the batching cylinder 9 enters the mixing tank 3 through the hose 11.
[0026] Please see Figure 1 , 2 As shown in Figures 3 and 5, a gear ring 18 is installed on the outer side of the bottom end of the mixing tank 3, a main drive gear 19 is installed on the top end of the rotating shaft 13, a support shaft 20 is rotatably installed on the bottom side of one end of the support frame 1, a driven gear 21 is installed on the top end of the support shaft 20, the main drive gear 19 and the driven gear 21 are connected by a toothed belt 22, and a circular gear 23 is installed on the bottom side of the support shaft 20, and the circular gear 23 is meshed with the gear ring 18.
[0027] One end of the rotating shaft 13 movably passes through the mixing tank 3 and extends to its bottom end. Two scrapers 24 are symmetrically installed on the outer side of the rotating shaft 13. The scrapers 24 are in contact with the inner wall of the mixing tank 3. Four sets of stirring blades 25, each consisting of three blades, are equidistantly installed on the outer side of the rotating shaft 13.
[0028] A discharge pipe 26 is connected to one side of the bottom of the mixing tank 3, and a discharge valve 27 is installed inside the discharge pipe 26. During operation, the rubber after mixing usually contains multiple components, which need to be evenly dispersed in the rubber to achieve the best effect. Therefore, it is necessary to stir the rubber after mixing. In the prior art, the stirring blade 25 usually makes a single circular motion, which will cause multiple components to not be able to fully contact the rubber. When the rotating shaft 13 rotates, the main drive gear 19 installed at the top of the rotating shaft 13 rotates accordingly. The main drive gear 19 drives the gear belt 22 to rotate. The rotation of the transmission gear 21 causes the support shaft 20 and the circular gear 23 to rotate accordingly. Since the circular gear 23 meshes with the gear ring 18, the rotation of the circular gear 23 drives the mixing barrel 3 to rotate in the opposite direction to the rotating shaft 13. At the same time, during the rotation of the rotating shaft 13, the scraper 24 can scrape off the raw materials adhering to the inner wall of the mixing barrel 3. The four sets of three stirring blades 25, which are equidistantly installed on the outside of the rotating shaft 13, also rotate, and the mixing barrel 3 also rotates in the opposite direction. The stirring blades 25 can fully stir the raw materials, enhance the mixing effect, and improve the mixing efficiency.
[0029] After the raw materials are fully mixed in the mixing tank 3, the operator opens the discharge valve 27 inside the discharge pipe 26 through the control panel 28. The mixed raw materials are discharged from the device through the discharge pipe 26, completing the entire batching and mixing process of rubber processing.
[0030] Working principle: Before the batching begins, the baffle 17 is in a horizontal position, blocking the outlet of the batching cylinder 9 to prevent the raw materials from falling prematurely. Then, the solid raw materials are poured into the batching cylinder 9. The drive motor 12 is started, and its output drives the rotating shaft 13 to rotate. The cam 14 at the top of the rotating shaft 13 rotates accordingly. During operation, the cam 14 contacts the outer side of the batching cylinder 9. When the cam 14 presses against the batching cylinder 9, the batching cylinder 9 causes the movable rod 6 to slide within the sleeve 5, stretching the tension spring 8. As the cam 14 presses against the outer side of the batching cylinder 9, the movable rod 6 slides within the sleeve 5, and the tension spring 8 is stretched. 4. As the rotation continues, the squeezing force of the cam 14 on the dispensing cylinder 9 disappears, the tension spring 8 returns to its original state, and pulls the dispensing cylinder 9 back to its initial position. This cycle repeats, and the dispensing cylinder 9 vibrates, causing the solid raw materials poured into the dispensing cylinder 9 to spread out evenly under the combined action of gravity and vibration, preventing the solid raw materials from piling up into small hills. The operator can read the amount of raw materials more accurately through the scale line 10 on the outside of the dispensing cylinder 9, reducing dispensing errors. At the same time, the vibration of the dispensing cylinder 9 can also reduce the phenomenon of blockage during feeding.
[0031] When the amount of raw material in the mixing cylinder 9 reaches the required value, the servo motor 15 is started through the control panel 28. The output end of the servo motor 15 drives the connecting shaft 16 to rotate. The baffle 17 located inside the mixing cylinder 9 on the outside of the connecting shaft 16 rotates accordingly. When the baffle 17 rotates to be perpendicular to the mixing cylinder 9, the discharge channel is opened, and the solid raw material in the mixing cylinder 9 enters the mixing tank 3 through the hose 11.
[0032] When the rotating shaft 13 rotates, the main drive gear 19 installed at the top of the rotating shaft 13 rotates accordingly. The main drive gear 19 drives the driven gear 21 to rotate through the toothed belt 22, thereby causing the support shaft 20 and the circular gear 23 to rotate as well. Since the circular gear 23 meshes with the gear ring 18, the rotation of the circular gear 23 drives the mixing barrel 3 to rotate in the opposite direction to the rotating shaft 13. At the same time, during the rotation of the rotating shaft 13, the scraper 24 can scrape off the raw materials adhering to the inner wall of the mixing barrel 3. The four sets of three stirring blades 25 installed at equal intervals on the outside of the rotating shaft 13 also rotate, and the mixing barrel 3 also rotates in the opposite direction. The stirring blades 25 can fully stir the raw materials, enhance the mixing effect, and improve the mixing efficiency.
[0033] After the raw materials are fully mixed in the mixing tank 3, the operator opens the discharge valve 27 inside the discharge pipe 26 through the control panel 28. The mixed raw materials are discharged from the device through the discharge pipe 26, completing the entire batching and mixing process of rubber processing.
