Description

Technical Field

[0001] The utility model relates to the technical field of ball-forming discs, in particular to a ball-forming disc which is easy to clean. Background Art

[0002] The balling disc is a device used for dry powder granulation and dry powder pre-wetting granulation, also known as a disc granulator or disc balling machine. Its working principle is to allow the raw material powder to be evenly moistened by atomized water in a double-shaft mixer to form a ball core with a very uniform particle size, and then sent to the balling disc for balling. This equipment is preferred in situations where uniform balling is required because of its good pre-wetting granulation effect. The balling disc will be attached with materials when in use. In order to facilitate cleaning, a balling disc with a cleaning structure must be used.

[0003] When the ball forming disk is in use, wet powder will stick to the inner wall of the ball forming disk. The existing ball forming disk generally removes the stuck material by adding a scraper inside the ball forming disk and cooperating with the rotation of the ball forming disk. However, since the scraped material is also easy to stick to the scraper, and the device lacks an integrated structure that can remove the material on the scraper, it is easy to cause material residue in the ball forming disk, thereby reducing the cleaning effect of the ball forming disk. For this reason, we provide a ball forming disk that is easy to clean. Utility Model Content

[0004] In order to solve the problem in the above background technology that materials are easily adhered to the scraper, resulting in material residues in the ball forming disk, thereby reducing the cleaning effect of the ball forming disk, the utility model provides a ball forming disk that is easy to clean.

[0005] The utility model adopts the following technical scheme to achieve: a ball-forming disk that is easy to clean, comprising:

[0006] A frame, on which a ball-forming disc body is obliquely arranged, a scraper is arranged inside the ball-forming disc body, and the scraper is fixedly connected to the frame through a connecting frame;

[0007] An anti-adhesion component, which includes a U-shaped scraping sleeve symmetrically and movably mounted on the outside of both sides of the scraper, a sliding rod fixedly connected to the connecting frame through a connecting seat, two groups of sliding blocks are slidably connected to the outside of the sliding rod, and the two groups of sliding blocks are fixedly connected to the same fixed frame, one end of the fixed frame is hinged to the U-shaped scraping sleeve with a connecting rod through a hinge, and the other end of the fixed frame is rotatably connected to a roller through a mounting seat, the outer sleeve of the sliding rod is provided with a spring, and the outside of the ball forming disk body is equidistantly circumferentially rotatably connected with protrusions.

[0008] As a further improvement of the above solution, both sides of the slide rod are fixedly connected to limit bars, and the sliding connection between the slider and the slide rod is symmetrically provided with limit grooves and is slidably connected to the limit bars.

[0009] As a further improvement of the above solution, the roller is in contact with the outer surface of the ball-forming disk body.

[0010] As a further improvement of the above solution, two ends of the spring are fixedly connected to the connecting seat and one side slider respectively.

[0011] As a further improvement of the above solution, the cross section of the protrusion is an obtuse triangle.

[0012] As a further improvement of the above solution, the length of the scraper is consistent with the radius of the ball-forming disk body.

[0013] As a further improvement of the above solution, semicircular grooves are provided on the two groups of U-shaped scraping sleeves at positions corresponding to the fixed connection of the scrapers.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model can drive the protrusion to make circular motion by rotating the ball-forming disc body. When the roller rolls onto the protrusion, the sliding cooperation between the slider and the slide rod can drive the fixed frame to move outward and stretch the spring. The hinge between the fixed frame and the U-shaped scraping sleeve and the connecting rod can drive the two sets of U-shaped scraping sleeves to move toward each other at the same time, so that the material adhered to the scraper surface can be scraped off. This can not only prevent the material from remaining inside the ball-forming disc body, but also ensure the good scraping effect of the scraper, and has strong practicality.

[0016] 2. When the roller rolls off the protrusion, the utility model utilizes the rebound effect of the spring to enable the roller to automatically and quickly reset itself, and during the resetting process, the roller will collide with the ball-forming disc body. The vibration generated by the collision can cause the material attached to the inner wall of the ball-forming disc body to fall off, thereby further improving the effect of removing the material adhering to the inner wall of the ball-forming disc body. At the same time, the spring will also drive the two sets of U-shaped scraping sleeves to automatically reset themselves when rebounding, and this process is repeated, so that the material can be prevented from adhering to the scraper surface, further improving the practicability of the device.

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. Example

[0024] Please combine Figure 1-4 , a ball-forming disk that is easy to clean in this embodiment includes:

[0025] A frame 1 is provided with a ball forming disc body 2 which is inclined on the frame 1. A scraper 3 is provided inside the ball forming disc body 2. The scraper 3 is fixedly connected to the frame 1 through a connecting frame 4. The length of the scraper 3 is consistent with the radius of the ball forming disc body 2, so as to ensure the thoroughness of scraping the material.

[0026] The anti-adhesion component includes a U-shaped scraping sleeve 101 symmetrically and movably sleeved on the outside of the scraper 3 on both sides, a sliding rod 102 is fixedly connected to the connecting frame 4 through a connecting seat, and two groups of sliders 103 are slidably connected to the outside of the sliding rod 102. The two groups of sliders 103 are fixedly connected to the same fixed frame 104. A connecting rod 105 is hinged between one end of the fixed frame 104 and the U-shaped scraping sleeve 101 through a hinge. The other end of the fixed frame 104 is rotatably connected to a roller 106 through a mounting seat. The roller 106 contacts the outer surface of the ball-forming disc body 2. The outer sleeve of the sliding rod 102 is provided with Spring 107, both ends of spring 107 are fixedly connected to the connecting seat and one side slider 103 respectively, the outside of the ball forming disc body 2 is equidistantly connected to the circumferential rotation with a protrusion 108, the cross-section of the protrusion 108 is an obtuse triangle, when the roller 106 leaves the protrusion 108, the roller 106 will not roll down along the inclined surface on the protrusion 108, but will directly hit the ball forming disc body 2, the two sets of U-shaped scraping sleeves 101 are provided with semicircular grooves 110 at the positions corresponding to the fixed connections of the scraper 3, which can prevent the fixed connection between the scraper 3 and the connecting frame 4 from affecting the movement of the U-shaped scraping sleeve 101.

[0027] The implementation principle of a ball forming disk that is easy to clean in the embodiment of the present application is as follows: after use, the device controls the ball forming disk body 2 to continue to rotate, and utilizes the cooperation of the scraper 3 to scrape off the material adhering to the inner wall of the ball forming disk body 2. At the same time, the ball forming disk body 2 rotates, causing the roller 106 to roll on its outer surface, and the rotation of the ball forming disk body 2 will also drive the protrusion 108 to make a circular motion together. When the roller 106 rolls onto the protrusion 108, the sliding cooperation between the slider 103 and the slide rod 102 can be utilized to drive the fixed frame 104 to move outward and stretch the spring 107. The hinge effect between the fixed frame 104 and the U-shaped scraping sleeve 101 and the connecting rod 105 can be utilized to drive the two groups of U-shaped scraping sleeves 101 to move toward each other at the same time, so that the scraper 3 surface adhering to the scraper 3 can be removed. The material can be scraped off, which can not only prevent the material from remaining inside the ball forming disc body 2, but also ensure the good scraping effect of the scraper 3. When the roller 106 rolls to the outermost side of the protrusion 108, the two groups of U-shaped scraping sleeves 101 just move to the middle of the scraper 3. When the roller 106 rolls away from the protrusion 108, the rebound effect of the spring 107 is used to make the roller 106 automatically and quickly reset, and during the resetting process, the roller 106 will collide with the ball forming disc body 2. The vibration generated by the collision can make the material attached to the inner wall of the ball forming disc body 2 fall off, thereby further improving the effect of removing the material adhering to the inner wall of the ball forming disc body 2. At the same time, the spring 107 will also drive the two groups of U-shaped scraping sleeves 101 to automatically reset when it rebounds. This is repeated, so that the material adhering to the surface of the scraper 3 can be avoided. Example

[0028] Based on Example 1, this embodiment is further improved in that: both sides of the sliding rod 102 are fixedly connected to the limiting strips 109, and the sliding connection between the slider 103 and the sliding rod 102 is symmetrically provided with limiting grooves and is slidingly connected to the limiting strips 109, which can limit the fixing frame 104 and prevent it from rotating outside the sliding rod 102.

[0029] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
