Technical Field
[0001] This utility model relates to the field of mixer technology, and in particular to an automatic feeder mixer for batching rubber and plastic insulation materials. Background Technology
[0002] Automatic loading and unloading mixers for rubber and plastic insulation material batching are specialized mechanical devices used in the production process of rubber and plastic insulation materials to automatically mix various ingredients. The batching stage is crucial in the production of rubber and plastic insulation materials, and the mixer, as a core piece of equipment, directly affects product quality and production efficiency. Currently, the widely used automatic loading and unloading mixers for rubber and plastic insulation material batching have significant deficiencies in the maintenance of their mixing blades. As a key component of the mixer, the mixing blades are prone to wear, deformation, or damage due to the characteristics of the materials and the complex stresses during the mixing process. Once the mixing blades exhibit these problems, existing mixers typically lack effective targeted maintenance mechanisms. Traditional mixers often require complete disassembly when dealing with mixing blade malfunctions. This process involves not only the mixing blades themselves but also the removal of numerous connected components, greatly increasing the workload and complexity of disassembly.
[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when a single stirring blade is damaged, the entire assembly needs to be disassembled, which may lead to problems such as missing, damaged or improperly installed parts during the disassembly process, affecting the normal operation of the equipment and increasing maintenance costs; therefore, in order to address the above problems, an automatic loading and unloading mixer for rubber and plastic insulation material batching is proposed. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that in the existing technology, when a single stirring blade is damaged, the whole machine needs to be disassembled, which may lead to the loss, damage or improper installation of some normally normal parts during the disassembly process, affecting the normal operation of the equipment and increasing maintenance costs. Therefore, an automatic loading and unloading mixer for rubber and plastic insulation material batching is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic loading and unloading mixer for batching rubber and plastic insulation materials, comprising a mixer body, a support frame mounted on the surface of the mixer body, a motor fixedly connected to the surface of the support frame, an auxiliary device provided at the output end of the motor, the auxiliary device including a rotating shaft, the rotating shaft fixedly connected to the output end of the motor, three fixed brackets fixedly connected to the arc surface of the rotating shaft, locking pins fixedly connected to both sides of the fixed brackets, a stirring blade slidably connected to the arc surface of the locking pins, two irregularly shaped plates fixedly connected to the surface of the fixed brackets, a rotating rod fixedly connected to the inner wall of the irregularly shaped plates, a limiting plate rotatably connected to the arc surface of the rotating rod, a threaded rod inserted into the inner thread of the limiting plate, and the threaded surface of the threaded rod threadedly connected to the stirring blade.
[0006] The aforementioned components achieve the following effects: by setting up auxiliary devices, the stirring blades of the stirring blade body can be disassembled individually. When the stirring blades are worn, deformed, or damaged, they can be directly disassembled for inspection and repair. Individual disassembly only addresses the problematic stirring blades, eliminating the need to replace other undamaged parts, thus reducing maintenance costs. This avoids the need for complete disassembly when a single stirring blade is damaged, which could lead to problems such as missing, damaged, or improperly installed parts during disassembly, affecting the normal operation of the equipment, increasing maintenance costs, and significantly increasing the workload and complexity of disassembly.
[0007] Preferably, the arc surface of the rotating rod is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the irregular plate and the limiting plate, respectively.
[0008] The aforementioned components achieve the following effect: by using the force of the torsion spring, the limiting plate is quickly and automatically rotated open and fixed at a certain angle, thus improving the convenience of the device.
[0009] Preferably, a cutting blade is fixedly connected to both sides of the stirring blade, and the cutting blade is blade-shaped.
[0010] The effect achieved by the above components is as follows: by setting the cutting blade, the cutting blade can cut and crush some larger particle agglomerates or lumps in the rubber and plastic insulation material during the mixing process, and refine them into smaller particles. This makes the material distribution in the mixer body more uniform and avoids the formation of local concentrations in the mixer body, thereby ensuring that various ingredients can be mixed evenly.
[0011] Preferably, two long rods are fixedly connected to the arc surface of the rotating shaft, and a scraper is fixedly connected to one end of each long rod. The scraper is slidably connected to the inner wall of the mixer body.
[0012] The effect achieved by the above-mentioned components is that by setting up scrapers, the rubber and plastic insulation material adhering to the inner wall of the mixer body can be cleaned off in time and allowed to flow back into the mainstream of materials. This avoids the accumulation of materials on the inner wall of the mixer body, which would prevent these materials from fully participating in the mixing and affect the uniformity of the rubber and plastic insulation material.
[0013] Preferably, the arc surface of the mixer body is provided with a measuring device, the measuring device including a conveying pipe, the conveying pipe being connected to the arc surface of the mixer body, a measuring cup being fixedly connected to one end of the conveying pipe, a circular hole being opened on the bottom surface of the measuring cup, the circular hole being connected to one end of the conveying pipe, an extension plate being fixedly connected to the surface of the measuring cup, a through hole being opened on the surface of the extension plate, a round rod being slidably connected to the inner wall of the through hole of the extension plate, a baffle being fixedly connected to one end of the round rod, the baffle being larger than the size of the circular hole of the measuring cup, an insert rod being slidably inserted into the extension plate, an insertion hole being opened on the arc surface of the round rod, the insert rod being slidably connected to the inner wall of the insertion hole of the round rod, and a pull plate being fixedly connected to one end of the insert rod.
[0014] The effect achieved by the above-mentioned components is as follows: by setting up a quantity control device, operators can accurately add chemical raw materials that are suitable for the properties of rubber and plastic insulation materials, ensuring that the proportion of each batch of rubber and plastic insulation materials remains highly consistent, effectively reducing the quality difference between batches, avoiding the material mixing errors caused by other imprecise methods, and thus ensuring the stability and consistency of product quality.
[0015] Preferably, a spring is fitted on the arc surface of the insertion rod, and the two ends of the spring are fixedly connected to the pull plate and the extension plate, respectively.
[0016] The effect achieved by the above components is that, under the action of the spring, the insertion rod automatically springs back and is inserted into the round rod insertion hole, thus improving the practicality of the device.
[0017] Preferably, a sealing gasket is fixedly connected to the surface of the baffle, and the surface of the sealing gasket is slidably connected to the graduated cup. The sealing gasket is made of rubber.
[0018] The effect achieved by the above components is that by setting a sealing gasket, the tiny gap between the baffle and the round hole of the graduated cup is filled, thus preventing the raw material from leaking out of the gap in the baffle and affecting the accuracy of the measuring device.
[0019] 1. In this utility model, by setting an auxiliary device, the stirring blades of the stirring blade body can be disassembled individually. When the stirring blades are worn, deformed, or damaged, they can be directly disassembled for inspection and repair. Individual disassembly only addresses the problematic stirring blades, without replacing other undamaged parts, thus reducing maintenance costs. This avoids the need for overall disassembly when a single stirring blade is damaged, which could lead to problems such as missing, damaged, or improperly installed parts during disassembly, affecting the normal operation of the equipment, increasing maintenance costs, and greatly increasing the workload and complexity of disassembly.
[0020] 2. In this utility model, by setting a quantity control device, operators can accurately add chemical raw materials that are suitable for the performance of rubber and plastic insulation materials, so that the proportion of each batch of rubber and plastic insulation materials is highly consistent, effectively reducing the quality difference between batches and avoiding the material error caused by other imprecise methods, thereby ensuring the stability and consistency of product quality.

[0029] Reference Figure 1 , Figure 2 and Figure 5 As shown, this utility model provides a technical solution: an automatic loading and unloading mixer for batching rubber and plastic insulation materials, including a mixer body 1, a support frame 2 mounted on the surface of the mixer body 1, a motor 3 fixedly connected to the surface of the support frame 2, and an auxiliary device 4 provided at the output end of the motor 3. By setting the auxiliary device 4, the mixing blades 6 of the mixing blade body 6 can be disassembled individually. When the mixing blade 6 is worn, deformed, or damaged, it can be directly disassembled for inspection and repair. Individual disassembly only addresses the problematic mixing blade 6, without replacing other undamaged parts, reducing maintenance costs and avoiding the need to replace individual mixing blades 6 when damaged. When disassembling, the entire machine needs to be disassembled. This may result in some normally functioning parts being lost, damaged, or improperly installed, affecting the normal operation of the equipment, increasing maintenance costs, and significantly increasing the workload and complexity of disassembly. The arc surface of the mixer body 1 is equipped with a measuring device 5. By setting the measuring device 5, the operator can accurately add chemical raw materials that are suitable for the properties of rubber and plastic insulation materials, ensuring that the proportion of each batch of rubber and plastic insulation materials is highly consistent. This effectively reduces the quality difference between batches and avoids the mixing error caused by other imprecise methods, thereby ensuring the stability and consistency of product quality.
[0030] The specific settings and functions of its auxiliary device 4 and control device 5 will be explained in detail below.
[0031] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the auxiliary device 4 includes a rotating shaft 401, which is fixedly connected to the output end of the motor 3. Three fixed brackets 402 are fixedly connected to the arc surface of the rotating shaft 401. A locking post 403 is fixedly connected to both sides of each fixed bracket 402. A stirring blade 6 is slidably connected to the arc surface of the locking post 403. Two irregularly shaped plates 405 are fixedly connected to the surface of the fixed bracket 402. A rotating rod 406 is fixedly connected to the inner wall of the irregularly shaped plate 405. The arc surface of the rotating rod 406 rotates... A limiting plate 407 is connected, and a threaded rod 408 is inserted into the internal thread of the limiting plate 407. The threaded surface of the threaded rod 408 is threadedly connected to the stirring blade 6. Two torsion springs 409 are sleeved on the arc surface of the rotating rod 406. The two ends of the torsion springs 409 are fixedly connected to the irregular plate 405 and the limiting plate 407 respectively. Under the force of the torsion springs 409, the limiting plate 407 is quickly and automatically rotated open and fixed at a certain angle, which improves the convenience of the device. Both sides of the stirring blade 6 are fixedly connected. A cutting blade 404 is attached, and the cutting blade 404 is blade-shaped. By setting the cutting blade 404, it is possible to cut and crush some larger particle agglomerates or lumps in the rubber and plastic insulation material during the mixing process, and refine them into smaller particles. This makes the material distribution in the mixer body 1 more uniform and avoids the formation of local concentrations in the mixer body 1, thereby ensuring that various ingredients can be mixed evenly. Two long rods 410 are fixedly connected to the arc surface of the rotating shaft 401. One end of the long rod 410 is fixedly connected to a scraper 411. The scraper 411 is slidably connected to the inner wall of the mixer body 1. By setting the scraper 411, the rubber and plastic insulation material adhering to the inner wall of the mixer body 1 is cleaned off in time, allowing it to flow back into the main material flow. This avoids the material accumulating on the inner wall of the mixer body 1, which would prevent this part of the material from fully participating in the mixing and affecting the uniformity of the rubber and plastic insulation material.
[0032] Reference Figure 5 , Figure 6 and Figure 7As shown, specifically, the measuring device 5 includes a conveying pipe 51, which is connected to the arc surface of the mixer body 1. A measuring cup 52 is fixedly connected to one end of the conveying pipe 51. A circular hole is opened on the bottom surface of the measuring cup 52, which is connected to one end of the conveying pipe 51. An extension plate 53 is fixedly connected to the surface of the measuring cup 52. A through hole is opened on the surface of the extension plate 53. A round rod 54 is slidably connected to the inner wall of the through hole of the extension plate 53. A baffle 55 is fixedly connected to one end of the round rod 54. The size of the baffle 55 is larger than the size of the circular hole of the measuring cup 52. An insert rod 56 is slidably inserted into the extension plate 53. An insertion hole is opened on the arc surface of the round rod 54, and the insert rod 56 is slidably connected to the inner wall of the insertion hole of the round rod 54. One end of the insertion rod 56 is fixedly connected to a pull plate 57. A spring 58 is fitted on the arc surface of the insertion rod 56. The two ends of the spring 58 are fixedly connected to the pull plate 57 and the extension plate 53, respectively. Under the force of the spring 58, the insertion rod 56 is automatically springed back and inserted into the hole of the round rod 54, which improves the practicality of the device. A sealing gasket 59 is fixedly connected to the surface of the baffle 55. The surface of the sealing gasket 59 is slidably connected to the graduated cup 52. The sealing gasket 59 is made of rubber. By setting the sealing gasket 59, the tiny gap between the baffle 55 and the round hole of the graduated cup 52 is filled, which prevents the raw material from leaking from the gap of the baffle 55 and affecting the accuracy of the measuring device 5.
[0033] Working principle: When the operator disassembles and repairs the mixing blade 6 of the mixer body 1 individually, rotating the threaded rod 408 causes it to rotate within the limiting plate 407 and then exit from the mixing blade 6. At this time, the torsion spring 409 releases the torsional force, causing the limiting plate 407 to rotate and open on the arc surface of the rotating rod 406 and be fixed at a certain angle. Then, the mixing blade 6 is removed from the arc surface of the retaining post 403, completing the individual disassembly and repair of the mixing blade 6. When the mixer body 1 is started after the repair is completed, the output end of the motor 3 drives the rotating shaft 401 to rotate within the mixer body 1. The rotating shaft 401 drives the fixed frame 402 to rotate, which in turn drives the mixing blade 6 to rotate. The mixing blade 6 then drives the cutting blade 404 to rotate. The cutting blade 404 cuts and crushes some larger particle agglomerates or lumps in the rubber and plastic insulation material, refining them into smaller particles. At this time, the long rod 410 will rotate on the rotating shaft. The 401 rotates together with the long rod 410, which drives the scraper 411 to rotate. The scraper 411 will contact the inner wall of the mixer body 1, and clean the rubber and plastic insulation material adhering to the inner wall of the mixer body 1 in time, allowing it to flow back into the mainstream of the material. By setting the auxiliary device 4, the mixing blade 6 of the mixing blade body 6 can be disassembled individually. When the mixing blade 6 is worn, deformed or damaged, it can be directly disassembled for inspection and repair. Individual disassembly only deals with the mixing blade 6 with the problem, without replacing other undamaged parts, reducing maintenance costs. It avoids the need to disassemble the whole when a single mixing blade 6 is damaged, which may lead to some normally normal parts being lost, damaged or not installed properly during the disassembly process, affecting the normal operation of the equipment, thereby increasing maintenance costs and greatly increasing the workload and complexity of disassembly.
[0034] When the operator needs to use the volume control device 5, the chemical raw material adapted to the properties of the rubber and plastic insulation material is placed into the graduated cup 52. The operator then observes the graduation marks on the graduated cup 52 until the precise dosage is reached. The operator then pulls the pull plate 57, which causes the insertion rod 56 to slide within the extension plate 53 and then slide out of the insertion hole of the round rod 54. At this time, the spring 58 is in a stretched state. The operator then rotates the round rod 54, causing the baffle 55 and the sealing gasket 59 to rotate away from the round hole of the graduated cup 52, allowing the chemical raw material to enter the delivery pipe 51. The chemical raw material then flows through the delivery pipe 51 into the mixer body 1. Then, rotate the round rod 54, causing the round rod 54 to move the baffle 55 and the sealing gasket 59 to the round hole of the graduated cup 52. Release the pull plate 57, and the spring 58 releases the tension force, causing the insertion rod 56 to automatically spring back and insert into the insertion hole of the round rod 54, thus completing the control of the amount of chemical raw materials. By setting the amount control device 5, the operator can accurately add chemical raw materials that are suitable for the performance of rubber and plastic insulation materials, so that the proportion of each batch of rubber and plastic insulation materials is highly consistent, effectively reducing the quality difference between batches and avoiding the material error caused by other non-precise methods, thereby ensuring the stability and consistency of product quality.
