Description
Technical Field
[0001] The invention relates to the technical field of internal spray coating machines, in particular to a rotary cup kit for internal spray coating machines. Background Art
[0002] The rotating cup kit is a container for clamping aluminum cans. Under high-speed rotation, the spray gun sprays isolation resin to evenly cover the inside of the aluminum can to achieve protection and isolation. However, the following three methods are usually used in the use of existing rotating cup kits; 1: Fix the rotating cup on the rotating shaft through a flat key and then fix it with screws. In this way, when changing the specifications, you need to loosen the screws first, and then use a special tool to pull out the rotating cup; when installing, you need to align the flat key and push it in, and tighten the screws. 2: The rotating cup is installed on the rotating pulley with a slight gap, and the tail is fixed with a retaining ring to prevent axial movement. It rotates by friction so that the isolation resin evenly covers the inner wall. In this way, when changing the specifications, you need to use a tool to remove the retaining ring and then pull out the rotating cup; when installing, you need to clamp it with a retaining ring. 3: The rotor cup is combined with the pulley through a concave-convex structure. A V-shaped groove is opened near the tail of the rotor cup. Three spring ball plungers are used on the pulley to accurately limit the rotor cup. Due to space limitations, the spring force is relatively small. In order to prevent the steel ball from being pushed out due to insufficient spring force and causing axial movement, a retaining ring groove is opened at the tail of the rotor cup, and a hand-pinch retaining ring (with a larger gap) is installed to limit it. In this way, when changing the specifications, you need to take out the hand-pinch retaining ring first, and then pull out the rotor cup; when installing, you need to clamp it with the retaining ring.
[0003] However, the number of rotors on the inner coating machine ranges from 31 to 46 or 52, which means that a large number of rotors need to be removed. Removing the rotors in a cumbersome manner consumes a lot of physical strength and time, resulting in low processing efficiency. Summary of the invention

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a rotor kit for an internal spraying machine, comprising a rotor body, a connecting piece and a pulley, characterized in that: the connecting piece is sleeved on the surface of the pulley, the pulley is sleeved on the left side of the rotor body surface, a steel ball sleeve is sleeved on the left side of the rotor body surface, a reset groove is opened on the left side of the inner wall surface of the steel ball sleeve, a compression spring is sleeved on the surface of the steel ball sleeve, a ball head circular hole is opened on the left side of the pulley surface, three ball head circular holes are arranged and distributed in a circular shape with equal distances, a steel ball is embedded in the ball head circular hole, a steel ball groove is opened on the left side of the rotor body surface, and limiting clamps are arranged on both sides of the pulley, and the limiting clamps are sleeved on the surface of the rotor body.

[0010] 2. The present invention provides a raised portion and a slot, so that when the user splices the rotor body and the pulley, the raised portion on the pulley can be inserted into the slot for splicing, thereby further improving the firmness of the rotor body after installation.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] like Figures 1 to 8 As shown, the rotary cup kit for the internal spraying machine provided by the present invention.
[0023] refer to Figure 4 and Figure 5 , both sides of the right side of the pulley 3 are provided with protrusions, both sides of the rotor body 1 are provided with slots 11, the inner material of the rotor body 1 is polyoxymethylene, and the outer material of the rotor body 1 is LV12.
[0024] As a technical optimization scheme of the present invention, by providing a protrusion and a slot 11, it is convenient for the user to splice the rotor body 1 with the pulley 3 by inserting the protrusion on the pulley 3 into the slot 11 for splicing, thereby further improving the firmness of the rotor body 1 after installation. The material of the rotor body 1 inside is polyformaldehyde, and the high rigidity, self-lubrication and fatigue resistance of polyformaldehyde are utilized to improve the service life and installation smoothness of the rotor body 1, making it convenient to push the aluminum can in, and the surface of the aluminum can will not be damaged during internal contact. The material of the outer part of the rotor body 1 is LV12, and the excellent physical properties of LV12 are utilized to improve the use effect of the rotor body 1.
[0025] refer to Figure 3 , the model of the steel ball 8 is 316 stainless steel.
[0026] As a technical optimization solution of the present invention, by setting the model of the steel ball 8 to 316 stainless steel and utilizing the excellent corrosion resistance and high temperature strength of 316 stainless steel, the steel ball 8 can resist the erosion of various corrosive media, thereby ensuring the long-term stable use of the steel ball 8.
[0027] The working principle and usage process of the present invention are as follows: when the rotor body 1 needs to be removed, the user can push the steel ball sleeve 4 to the right to compress the compression spring 6, and at the same time, the reset groove 5 opened inside the steel ball sleeve 4 can correspond to the ball head circular hole 7, and then the user's other hand directly pulls out the rotor body 1 with force, so that the steel ball 8 is pushed by the steel ball groove 9 to move upward to the corresponding reset groove 5. At this time, the steel ball 8 no longer limits the rotor body 1, and then the user can directly take the rotor body 1 out of the pulley 3.
[0028] When the rotor body 1 needs to be installed, the steel ball ferrule 4 is pushed to the right to compress the compression spring 6, and then the left side of the rotor body 1 is directly inserted into the interior of the pulley 3, and then the steel ball ferrule 4 is loosened. Then, under the elastic force of the compression spring 6, the large end surface of the left side of the steel ball ferrule 4 is tightly against the limit spring, and the axial position is always kept relatively still, so that the steel ball 8 is always restricted by the inner ring of the steel ball ferrule 4 in the ball head circular hole 7 and cannot move up, thereby ensuring that when the rotor body 1 is rotating or only subjected to artificial tension, the rotor will not produce axial displacement and there is a slight amount of machining gap movement, which can be ignored, thereby achieving the use effect.
[0029] To sum up: the rotor kit for the internal spraying machine, by setting the compression spring 6, pushes the steel ball sleeve 4 to the right, so that the compression spring 6 is compressed, and then the other hand directly pulls out the rotor body 1 with force, which solves the problem that the number of rotors on the internal coating machine is as few as 31 and as many as 46 or 52, resulting in a large number of rotors that need to be removed, and removing the rotors in a cumbersome way will consume a lot of physical strength and time costs, resulting in low processing efficiency.
