[0001] The present application belongs to the technical field of eraser processing and production, and in particular relates to a mixing device for eraser processing and production. Background Art

[0002] Eraser is a common tool. During its processing, multiple materials are crushed and mixed. After mixing, the mixed materials are placed in an extruder and extruded through heating to form long strips of eraser materials, which are then cut into erasers.

[0003] The existing mixing equipment is installed, CN217514309U, such as the patent with publication number CN217514309U, which discloses a mixing equipment for eraser processing and production, including an equipment body, the upper outer surface of the equipment body is provided with a feed port and a first motor, and the first motor is located on one side of the feed port, the inner wall of the first motor is provided with a central axis, the outer wall of the central axis is provided with a cleaning mechanism and a mixing stick, and the mixing stick is located at the lower end of the cleaning mechanism, the lower outer surface of the equipment body is provided with a first discharge port and a support leg, and the support leg is located on one side of the first discharge port. The above patent can scrub the inside of the equipment through the internal scraper and bristles, but the equipment body is an integrated structure and cannot be easily disassembled. Once the internal cleaning mechanism is damaged, the cleaning work cannot be completed, and the integrated structure makes it very inconvenient to disassemble after being damaged, and needs to be improved. Utility Model Content

[0004] The purpose of this application is to provide a mixing device for eraser processing and production, which can solve the above problems.

[0005] The purpose of this application is to provide a mixing device for eraser processing and production, including:

[0006] The first mixing mechanism comprises a cylinder, a cylinder cover is provided at the top of the cylinder, a material guide port is provided at the bottom, and a material feed port is provided on the cylinder cover;

[0007] A stirring device is arranged on the cylinder;

[0008] The second mixing mechanism is arranged at the bottom of the first mixing mechanism and is connected to the material guide port, and includes a housing, a material outlet arranged at one end of the housing, a rotating shaft arranged in the housing, a spiral sheet arranged on the rotating shaft, and a first servo motor driving the rotating shaft to rotate;

[0009] The utility model further comprises a mounting mechanism arranged between the cylinder body and the cylinder cover, and the cylinder body and the cylinder cover are connected via the mounting mechanism.

[0010] The above-mentioned mixing equipment for eraser processing and production is adopted. The first mixing mechanism fully mixes the eraser raw material in the cylinder through the stirring device to ensure that various components are evenly distributed, providing a stable raw material basis for subsequent processing. The second mixing mechanism utilizes the rotation of the spiral sheet and the rotating shaft to smoothly convey the material mixed by the first mixing mechanism to the discharge port while further stirring, thereby reducing the possibility of material blockage and improving production efficiency. The setting of the mounting mechanism ensures a firm connection between the cylinder and the cylinder cover, which can avoid leakage problems that may occur during mixing and conveying, and can also facilitate the installation and disassembly between the cylinder and the cylinder cover, thereby facilitating cleaning and maintenance of the inside of the cylinder.

[0011] Furthermore, the stirring device comprises:

[0012] A second servo motor is disposed on the cylinder;

[0013] A stirring rod is arranged in the cylinder, and a plurality of stirring blades are arranged on the stirring rod;

[0014] The stirring rod is also provided with a scraping rod which contacts the inner wall of the cylinder.

[0015] The second servo motor, as the driving source of the stirring device, can provide stable power to ensure that the stirring rod and the stirring blades rotate at an appropriate speed. The user can adjust the intensity and direction of stirring according to the properties and mixing requirements of the eraser raw materials. The multiple stirring blades arranged on the stirring rod can produce a strong stirring effect in the cylinder to ensure that the eraser raw materials are fully mixed. The scraper rod is in contact with the inner wall of the cylinder, and can scrape off the raw materials attached to the cylinder wall during the stirring process to prevent the raw materials from remaining. By scraping off the residues on the cylinder wall, it can also ensure that all raw materials are involved in the mixing process, thereby improving the uniformity and quality of the mixing. In addition, the scraper rod can reduce the residue of raw materials on the cylinder wall, reducing the frequency and cost of cleaning and maintenance.

[0016] Further: the installation mechanism includes:

[0017] A positioning protrusion is arranged on the cylinder cover, a cavity is arranged in the positioning protrusion, and a limiting through hole is arranged on the positioning protrusion;

[0018] A mounting groove is provided on the cylinder, wherein a mounting half ring is provided in the mounting groove, and a threaded hole is provided on the mounting half ring;

[0019] A fastener, the end of which is provided with threads adapted to the threaded hole;

[0020] A positioning hole group, comprising a first through hole arranged on the cylinder cover and a second through hole arranged on the cylinder body;

[0021] Wherein, the limiting through hole, the cavity, the first through hole, the second through hole and the threaded hole are sequentially connected to each other.

[0022] The installation mechanism can ensure a stable connection between the cylinder body and the cylinder cover, and also provide a convenient disassembly method, which is convenient for cleaning and maintenance of the equipment. During installation, the fastener passes through the limiting through hole, the cavity, the first through hole, and the second through hole in sequence and is connected to the threaded hole. Since the threaded hole is arranged on the installation half ring, and the installation half ring is detachably installed in the installation groove, it is only necessary to place the installation half ring, align the holes, and then tighten the fasteners. It is quick and convenient, and disassembly only requires unscrewing the fasteners. At the same time, the contact area can be increased and the installation stability of the fastener can be improved by setting the positioning protrusions. The threaded holes are only arranged on the installation half ring. Therefore, even if the threaded holes are worn, it is only necessary to replace the installation half ring, which will not affect the cylinder body and the cylinder cover, thereby reducing maintenance losses.

[0023] Furthermore, the inner diameters of the cavity, the first through hole, and the second through hole are the same, and the inner diameters of the cavity, the first through hole, and the second through hole are larger than the inner diameter of the limiting through hole, and the inner diameter of the limiting through hole is the same as the diameter of the fastener.

[0024] The inner diameters of the cavity, the first through hole, and the second through hole are the same and larger than the inner diameter of the limiting through hole. Therefore, the fastener will not contact the inner walls of the cavity, the first through hole, and the second through hole during tightening or loosening, thereby not causing wear, effectively avoiding damage to the cylinder body and the cylinder cover, and avoiding unnecessary losses.

[0025] Furthermore, the installation mechanism also includes:

[0026] A first limiting ring is arranged on the fastener;

[0027] The second limiting ring is arranged in the first through hole and is located below the first limiting ring.

[0028] A spring is arranged between the first limiting ring and the second limiting ring;

[0029] Wherein, the spring sleeve is arranged on the fastener.

[0030] When installing the cylinder body and the cylinder cover, as the fasteners are gradually tightened, the first limit ring and the second limit ring squeeze the spring, thereby improving the installation effect of the cylinder body and the cylinder cover. When disassembling the cylinder body and the cylinder cover, as the fasteners are gradually loosened, the spring resets and pushes the first limit ring and the second limit ring, thereby facilitating the user to disassemble the cylinder body and the cylinder cover and improving the disassembly efficiency.

[0031] Furthermore, a gasket is provided between the fastener and the positioning protrusion.

[0032] The setting of the gasket can fill and compress the tiny gap between the positioning protrusion and the cylinder body when the fastener is tightened, thereby enhancing the sealing between the cylinder cover and the cylinder body. It can also disperse the pressure generated by the fastener to avoid pressure concentration. In addition, the gasket can compensate for the manufacturing error or installation error between the cylinder cover and the cylinder body to a certain extent, making the installation process more flexible and convenient.

[0033] The beneficial effects of this application are:

[0034] 1. By setting up the installation mechanism, a firm connection between the cylinder and the cylinder cover is ensured, which can avoid leakage problems that may occur during mixing and transportation, and can also facilitate the installation and disassembly between the cylinder and the cylinder cover, thereby facilitating cleaning and maintenance of the inside of the cylinder;

[0035] 2. The contact area can be increased by setting the positioning protrusion, which improves the installation stability of the fastener. The threaded hole is only set on the installation half ring. Therefore, even if the threaded hole is worn, only the installation half ring needs to be replaced, which will not affect the cylinder body and cylinder cover, thus reducing the maintenance loss.

[0036] 3. When installing the cylinder body and the cylinder cover, as the fasteners are gradually tightened, the first limit ring and the second limit ring squeeze the spring, thereby improving the installation effect of the cylinder body and the cylinder cover. When disassembling the cylinder body and the cylinder cover, as the fasteners are gradually loosened, the spring resets and pushes the first limit ring and the second limit ring, thereby facilitating the user to disassemble the cylinder body and the cylinder cover and improving the disassembly efficiency.

[0060] like Figure 2 and Figure 3 As shown, the mounting mechanism 400 includes:

[0061] The positioning protrusion 410 is disposed on the cylinder cover 120 , a cavity 411 is disposed in the positioning protrusion 410 , and a limiting through hole 412 is disposed on the positioning protrusion 410 ;

[0066] In the embodiment of the present application, the installation mechanism 400 is provided to ensure a stable connection between the cylinder body 110 and the cylinder cover 120, and a convenient disassembly method is also provided to facilitate cleaning and maintenance of the device. During installation, the fastener 440 passes through the limiting through hole 412, the cavity 411, the first through hole 451, and the second through hole 452 in sequence and is connected to the threaded hole 431, wherein, since the threaded hole 431 is provided on the installation semi-ring 430, and the installation semi-ring 430 is detachably installed in the installation groove 420, it is only necessary to place the installation semi-ring 430, align the holes, and then tighten the fastener 440, which is quick and convenient, and the disassembly only requires each fastener 440 to be screwed out.
