Description

Technical Field

[0001] The invention relates to the field of machinery, in particular to an emulsifying machine. Background Art

[0002] Most existing emulsifiers have scrapers added to the stirring mechanism. The scrapers can push the material to move and improve the emulsification effect. On the other hand, they can scrape the material on the inner wall of the pot to clean the pot. However, most existing scrapers are fixedly connected to the stirring mechanism, which has the following problems: 1. The scraper hard scrapes against the pot, causing the scraper to be easily damaged; 2. The scraper size needs to be customized according to the inner diameter of the pot, which cannot meet the requirement that one set of scrapers is suitable for pots with multiple inner diameters. Summary of the invention

[0003] The object of the present invention is to provide a self-protecting emulsifier equipped with a rotatable scraper to solve the above technical problems.

[0004] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0018] The left side of the pot cover of the self-protecting emulsifier equipped with a rotatable scraper is provided with a left support ear 51 extending to the left, and the right side is provided with a right support ear 52 extending to the right. The top of the main oil cylinder is provided with a left connecting seat 41, and the top of the main oil cylinder 11 extends from the fourth bracket 21 and is fixed to the bottom of the left support ear by bolts. The top of the auxiliary oil cylinder 12 is provided with a right connecting seat 42, and the top of the auxiliary oil cylinder 12 extends from the fifth bracket 22 and is fixed to the bottom of the right support ear by bolts.

[0019] The main oil cylinder 11 and the auxiliary oil cylinder 12 are synchronous oil cylinders that are raised and lowered synchronously. Synchronous lifting and lowering can be achieved by connecting oil pipes in series. The main oil cylinder 11 is provided with a main oil cylinder sleeve 31 on its outer sleeve, and the auxiliary oil cylinder 12 is provided with an auxiliary oil cylinder sleeve 32 on its outer sleeve. The main oil cylinder sleeve 31 is fixedly connected to the fourth bracket 21 from the inner side of the fourth bracket 21, and the auxiliary oil cylinder sleeve 32 is fixedly connected to the fifth bracket 22 from the inner side of the fifth bracket 22. Thus, the main oil cylinder sleeve 31 and the auxiliary oil cylinder sleeve 32 are used to reduce the eccentric load on the oil cylinder piston. The main oil cylinder sleeve 31 and the auxiliary oil cylinder sleeve 32 are respectively sleeved on the upper part of the main oil cylinder and the auxiliary oil cylinder, and the inner side walls of the main oil cylinder sleeve 31 and the auxiliary oil cylinder sleeve 32 are provided with an annular groove with an opening facing inward, and an anti-skid pad can be provided in the annular groove, so as to utilize the annular groove to elastically clamp the oil cylinder. Preferably, four annular grooves are arranged at equal intervals on the upper part of the main cylinder sleeve 31 and the auxiliary cylinder sleeve 32, and five annular grooves are arranged at equal intervals on the lower part of the main cylinder sleeve 31 and the auxiliary cylinder sleeve 32. The height of the groove wall of the annular groove is lower as it is closer to the end of the cylinder sleeve, thereby forming a trumpet-shaped opening to facilitate the up and down movement of the cylinder.

[0020] The homogenizer 9 is located on the left side of the pot body 6, and the stirring motor 10 is located on the right side of the pot cover, so that the weight of the emulsifier is relatively balanced to disperse the force of the bracket more evenly. An observation window can be opened on the pot cover, and the observation window is located on the rear side of the pot cover. The self-protection emulsifier equipped with a rotatable scraper can also include a sixth bracket located in the vertical direction, the bottom of the sixth bracket is fixedly connected to the first bracket, and the sixth bracket is welded to the rear of the pot body 6. Thereby, a triangular support is formed for the pot body 6 to improve the stability of the pot body 6. The sixth bracket is a solid bracket, and grooves with openings facing backwards can be provided at equal intervals on the sixth bracket. The staff can use the grooves to climb the pot body 6 to facilitate observation from the observation window.

[0021] The main oil cylinder and the auxiliary oil cylinder both include an outer sleeve 114 and an inner sleeve 113 located inside the outer sleeve. An oil cavity is arranged inside the outer sleeve, with the outer sleeve at the top and the inner sleeve at the bottom.

[0022] The stirring mechanism includes a main stirring shaft in a cylindrical shape, on which a first paddle 81 is symmetrically arranged. The stirring mechanism also includes a secondary stirring shaft 84 in a "U" shape, on the inner side of which a second paddle 82 is symmetrically arranged, the first paddle 81 and the second paddle 82 are arranged alternately, and the interlaced area is not less than one-third of the length of the first paddle, and not less than one-third of the length of the second paddle. A scraper 83 is provided on the outer side of the secondary stirring shaft, and the scraper 83 is rotatably connected to the secondary stirring shaft 84, and the positions of each scraper are staggered. The rotation angle of the scraper 83 is 15° to -15°. On the one hand, relative to the fixedly connected scraper, the rotating connection can make the scraper elastically contact the inner wall of the pot body, thereby avoiding damage to the scraper. On the other hand, the distance from the scraper to the central axis of the pot body can be adjusted by the scraper angle to adapt to pot bodies with different inner diameters. The secondary stirring shaft 84 is provided with a notch opening outward, and a blind hole 841 is provided on the side wall of the notch. The scraper 83 is provided with an extension plate 831 that can be inserted into the notch, and both ends of the extension plate 831 are provided with cylindrical protrusions 833 inserted into the blind hole 841, and the cylindrical protrusions 833 are used as the rotating shaft of the scraper 83. The blind hole 841 is an elliptical hole, and the cylindrical protrusion 833 can move along the long axis direction in the elliptical hole, and the long axis direction of the elliptical hole is perpendicular to the central axis of the pot body. Therefore, the scraper can not only rotate, but also move in the radial direction of the pot body. This design not only allows the scraper to be connected to the secondary stirring shaft by tilting the scraper, but also allows the scraper to have more active directions, so as to adapt to more changes in the inner wall of the pot body. More importantly, this structure is convenient for cleaning between the cylindrical protrusion and the blind hole during later cleaning. Preferably, a strip-shaped notch 842 is provided on the side of the blind hole 841 away from the central axis of the pot body, so that the material or cleaning water in the blind hole can be thrown out by using the notch. The diameter of the notch is smaller than the outer diameter of the cylindrical protrusion. There is no need to worry about the scraper coming off during use. During use, the secondary stirring shaft drives the scraper to rotate, and the scraper is subjected to the centrifugal force. The cylindrical protrusion is pressed against the outside of the blind hole, and the scraper presses against the inner wall of the pot body. Hemispherical spherical protrusions 832 are provided on both sides of the extension plate. During the rotation of the scraper, the spherical protrusion will rest on the bottom of the notch of the secondary stirring shaft, thereby limiting the continued rotation of the scraper. The use of a spherical protrusion structure can effectively improve the adhesion of materials and facilitate flushing.
