Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving pulverizing equipment, and in particular to an energy-saving pulverizer and process for powder coating production. Background Art

[0002] After the raw materials of powder coating are prepared into blocks or granules, they need to be put into a crusher. Through impact or grinding, the raw materials are broken down from larger particles into powder. Powdered coatings are easier to color and easier to mix with curing agents to achieve the desired coating effect.

[0003] Traditional crushers are widely used in the engineering field, but due to the limitations of their structure and working principle, there are often some problems that cannot be ignored. For example, traditional crushers often have a relatively simple crushing mode, which limits their adaptability to diverse material processing needs. In addition, existing crushers lack the utilization of redundant torque of the motor, resulting in energy waste. When processing materials of different hardness, toughness or structure, traditional crushers may not provide ideal crushing effects. For example, for materials with strong toughness, the expected crushing particle size may not be achieved due to insufficient crushing force. This single crushing mode makes traditional crushers appear powerless when facing diverse material processing needs, and they cannot be flexibly adjusted to adapt to the characteristics of different materials, thus affecting processing efficiency and product quality. Existing equipment always relies on the motor to provide power during the crushing process. During the operation of the motor, some redundant kinetic energy is not used, resulting in energy loss.

[0011] Furthermore, grinding grooves are formed on the top of the grinding disc and the outer side of the material roller, and the grinding grooves are in a grid shape.

[0012] Furthermore, the guiding mechanism includes a sleeve arranged in a ring array in the middle of the shell, a universal joint arranged inside the sleeve, a hexagonal prism arranged at the bottom of the universal joint, a spring sleeved on the outside of the hexagonal prism, a rotating plate arranged on the outside of the spring, a deep hole is opened on the side of the rotating plate close to the sleeve, the deep hole is sleeved on the outside of the spring, the top and bottom of the spring are fixedly connected to the top of the deep hole and the bottom of the hexagonal prism respectively, a pulley arranged on the side of the universal joint away from the rotating plate, a round belt sleeved on the outside of two adjacent pulleys, a protective shell arranged on the outside of the shell, a knob arranged on the side of the protective shell away from the discharge pipe, and a damping block arranged on the side of the protective shell close to the knob, the inner side of the damping block is rotatably connected to the knob, and the side of the knob close to the outside is fixedly connected to the nearest pulley.

[0013] Furthermore, the outer edge of the rotating plate is fan-shaped, and two connecting grooves are formed on the outer side of the pulley.

[0014] Furthermore, the sleeve is L-shaped and has a cavity inside.

[0015] Another object of the present invention is to provide a process based on powder coating production, the purpose of which is to industrially produce powder coatings.

[0016] To achieve the above object, the present invention provides the following technical solution: a process based on powder coating production, comprising the following steps:

[0017] First, prepare the required raw materials according to the recipe requirements and add them into the mixer in proportion for thorough mixing;

[0018] Secondly, the mixed raw materials are melted and extruded through a hot melt extruder to make them into a uniform liquid state;

[0019] Then, the raw materials after hot melt extrusion are divided into small pieces and then put into the hopper of the crusher. The raw materials enter the crusher through the hopper and are then crushed into powder by the crushing mechanism. During the crushing process, the staff can adjust the crusher to different working modes through the guide mechanism according to actual production needs.

Through the crushing mechanism, the raw materials entering the machine can be impact crushed and rolled shear crushed, so that the crusher can process various raw materials more efficiently. Impact crushing and rolling shear crushing can be targeted at materials of different properties, which helps to improve the crushing efficiency and ensure that the particle size distribution of the final product is more uniform. By setting the impact crushing and rolling shear crushing mechanisms, the crusher can better adapt to the processing needs of different raw materials, thereby improving its application range and flexibility, and can utilize the extra power of the motor to make the equipment more energy-efficient.

This design enables the crusher to flexibly adjust the crushing process according to different raw material characteristics and processing requirements, thereby improving the applicability of the equipment. By setting the guide mechanism, the crusher can better meet the diversified production needs and improve production efficiency and product quality.

[0025] 3. By setting pulleys and round belts, and connecting different pulleys and round belts, multiple turntables are connected. When one of the turntables starts to rotate, the friction between the round belt and the pulley drives the other turntables to rotate together. This method can ensure that the rotation of each turntable remains synchronized and avoid asynchronous situations. By setting pulleys and round belts, synchronous rotation between different turntables can be achieved, thereby improving the stability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0041] Example 1, reference Figures 1-12 , which is the first embodiment of the present invention, provides an energy-saving crusher for powder coating production, including a cover 1, a motor 2 fixedly connected to the inside of the cover 1, a fan 3 fixedly connected to the top of the motor 2, a shell 4 fixedly connected to the top of the cover 1, a hopper 5 fixedly connected to the top of the shell 4, and also includes a crushing mechanism 6 installed inside the shell 4, and a guiding mechanism 7 installed on the inner wall of the shell 4 for guiding materials; the crushing mechanism 6 includes a rotating shaft 61 fixedly connected to the top of the motor 2, the rotating shaft 61 rotates synchronously with the output shaft of the motor 2, an impeller 62 fixedly connected to the top of the rotating shaft 61, a plurality of annular arrays fixedly connected to the inner wall of the shell 4 near the top of the block 63, the impeller 62 throws the raw material to the block 63 by high-speed rotation, a baffle 64 fixedly connected to the bottom edge of the impeller 62, the raw material is rebounded to the baffle 64, and a grinding unit assembled in the middle of the inner wall of the shell 4 for grinding the raw material.

[0042] Specifically, the cover 1 provides impact protection for the motor 2 and provides support for the entire equipment. The motor 2 provides crushing power. The fan 3 rotates with the output shaft of the motor 2 and disturbs the air inside the cover 1 while rotating, thereby using the redundant power of the motor 2 to dissipate heat inside the cover 1, thereby achieving energy-saving effects. The moving parts inside the shell 4 provide working space. The hopper 5 is used to put in raw materials. The rotating shaft 61 transmits the power of the motor 2. The impeller 62 rotates with the rotating shaft 61 and uses the kinetic energy and centrifugal force generated by the rotation to impact and crush the raw materials and throw the raw materials to the block 63. The baffle 64 blocks the raw materials that rebound and fall by the block 63, and at the same time guides the raw materials to fall close to the inner wall of the shell 4. The crushing mechanism 6 can perform impact crushing and rolling and shearing crushing on the raw materials entering the machine, so that the crusher can process various raw materials more efficiently. Impact crushing and rolling and shearing crushing can be targeted at materials of different properties, which helps to improve crushing efficiency and ensure that the particle size distribution of the final product is more uniform. By setting the impact crushing and rolling and shearing crushing mechanisms 6, the crusher can better adapt to the processing requirements of different raw materials, thereby improving its application range and flexibility.

[0043] Reference Figure 4 A feed hole is provided at the top of the impeller 62, and a conical material guide platform is provided on the inner side of the impeller 62.

[0044] Specifically, the raw material hopper 5 falls toward the feed hole and diffuses toward the periphery of the truncated cone under the action of the truncated cone slope.

[0045] Reference Figure 5-Figure 8 The grinding unit includes a sleeve 65 rotatably connected to the bottom of the shell 4, a connecting ring 66 fixedly connected to the top of the sleeve 65, a plurality of annular arrays of support shafts 67 fixedly connected to the outside of the connecting ring 66, a material roller 68 rotatably connected to the outside of the support shaft 67, a grinding disc 69 fixedly connected to the middle of the inner wall of the shell 4, a threaded hole 610 opened at the bottom of the sleeve 65 and passing through the bottom of the rotating shaft 61, a bolt 611 threadedly connected to the inside of the threaded hole 610, and a discharge pipe 612 fixedly connected to the bottom of the shell 4.

[0046] Specifically, when the sleeve 65 rotates, it drives the connecting ring 66 to rotate synchronously. The connecting ring 66 also drives several support shafts 67 to rotate. The support shafts 67 drive the connected material rollers 68 to revolve around the sleeve 65. The grinding disc 69 cooperates with the material rollers 68 to grind the raw materials. After the bolts 611 and the threaded holes 610 cooperate, the sleeve 65 and the rotating shaft 61 are locked, so that the two rotate synchronously.

[0047] Reference Figure 5 and Figure 8 A limiting hole is provided at the bottom of the housing 4, and a limiting ring is provided at the bottom of the sleeve 65, which is rotatably connected to the inside of the limiting hole.

[0048] Specifically, the housing 4 is connected to the limiting ring of the shaft sleeve 65 through the limiting hole. The limiting hole and the limiting ring limit the shaft sleeve 65 so that it can only rotate in the original position.

[0049] Reference Figure 6 and Figure 7 The top of the grinding disc 69 and the outer side of the material roller 68 are both provided with grinding grooves, and the grinding grooves are in a grid shape.

[0050] Specifically, when the grinding disc 69 and the material roller 68 rotate relative to each other, the raw material can be sheared and crushed through the grinding grooves.

[0051] Example 2, reference Figures 9-12 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the guide mechanism 7 includes a plurality of sleeves 71 fixedly connected to the middle of the housing 4 in an annular array, a universal joint 72 rotatably connected to the inside of the sleeve 71, a hexagonal prism 73 fixedly connected to the bottom of the universal joint 72, a spring 74 sleeved on the outside of the hexagonal prism 73, a rotating plate 75 sleeved on the outside of the spring 74, a deep hole 76 is opened on the side of the rotating plate 75 close to the sleeve 71, the deep hole 76 is sleeved on the outside of the spring 74, and the top and bottom of the spring 74 are respectively connected to the deep hole 76. 6 and the bottom of the hexagonal prism 73 are fixedly connected, fixedly connected to the pulley 77 on the side of the universal joint 72 away from the rotating plate 75, a round belt 78 is sleeved on the outside of the two adjacent pulleys 77, fixedly connected to the protective shell 79 on the outside of the outer shell 4, a knob 710 is rotatably connected to the side of the protective shell 79 away from the discharge pipe 612, a damping block 711 is fixedly connected to the side of the protective shell 79 close to the knob 710, the inner side of the damping block 711 is rotatably connected to the knob 710, and the side of the knob 710 close to the outside is fixedly connected to the nearest pulley 77.

[0052] Specifically, the sleeve 71 can accommodate the universal joint 72 to move inside and provide protection for the universal joint 72, so that the universal joint 72 can transmit the torque from the pulley 77. The hexagonal prism 73 drives the rotating plate 75 to rotate together when rotating. The spring 74 continuously applies force to the rotating plate 75 to move the rotating plate 75 toward the direction of the nearest universal joint 72. When the top surface of the rotating plate 75 is facing upward, it can guide the raw materials falling from the top to the area of ​​the grinding unit. The deep hole 76 accommodates the hexagonal prism 73 and allows the spring 74 to rotate. The belt pulleys 77 are connected to each other by a circular belt 78. When any belt pulley 77 rotates, the other belt pulleys 77 can rotate synchronously under the joint action of several circular belts 78. The protective shell 79 isolates the belt pulleys 77 and the circular belt 78 inside itself and provides a fixed point for the damping block 711. When the knob 710 is rotated, it can drive the belt pulley 77 connected to it to rotate. The damping block 711 limits the knob 710 through friction, so that the knob 710 cannot rotate on its own without external force, guiding Mechanism 7 can control the opening and closing of the grinding function of the crusher. The user can select the appropriate crushing method by operating the guide mechanism 7 according to actual production needs. When the grinding function is required, the guide mechanism 7 can guide the raw materials to the grinding area for fine crushing, avoiding unnecessary grinding process. This design enables the crusher to flexibly adjust the crushing process according to different raw material characteristics and processing requirements, thereby improving the applicability of the equipment. By setting the guide mechanism 7, the crusher can better meet diversified production needs, improve production efficiency and product quality, and connect multiple rotating plates 75 through the connection between different pulleys 77 and round belts 78. When one of the rotating plates 75 starts to rotate, the friction between the round belt 78 and the pulley 77 drives the other rotating plates 75 to rotate together. This method can ensure that the rotation of each rotating plate 75 remains synchronized, avoiding the occurrence of asynchronous situations. By setting the pulley 77 and the round belt 78, the synchronous rotation of different rotating plates 75 can be achieved, thereby improving the stability of the equipment.

[0053] Reference Figure 9 and Figure 10 The outer edge of the rotating plate 75 is fan-shaped, and the outer side of the pulley 77 has two connecting grooves.

[0054] Specifically, a plurality of rotating plates 75 can be combined into a complete circular ring shape, which is connected to the round belt 78 through the connecting groove.

[0055] Reference Figure 10 and Figure 11 The sleeve 71 is L-shaped and has a cavity inside.

[0056] Specifically, the shape of the sleeve 71 is adapted to the transmission angle of the universal joint 72 and isolates the universal joint 72 from the outside world. The remaining structure is the same as that of the first embodiment.

[0057] The working principle of the present invention is as follows: by rotating the bolt 611, the bolt 611 enters the threaded hole 610, and connects the sleeve 65 and the rotating shaft 61, so that the two keep synchronous movement, and then rotate the knob 710. When the rotating force is greater than the friction between the knob 710 and the damping block 711, the knob 710 will drive the pulley 77 connected thereto to rotate, and after the rotation is driven, the other pulleys 77 are rotated synchronously through the round belt 78 connected thereto. When the pulley 77 rotates, the hexagonal prism 73 rotates through the universal joint 72, and the hexagonal prism 73 drives the rotating plate 75 to rotate, so that the rotating plate 75 is in a vertical state, and the motor 2 is started. The output shaft of the motor 2 drives the fan 3 to rotate. The fan 3 generates airflow to cool the motor 2 and utilizes the redundant torque of the motor 2. After the motor 2 rotates, the impeller 62 is driven to rotate through the rotating shaft 61. At this time, the raw material is put into the hopper 5, and the raw material falls to the impeller 62 through the hopper 5. The raw material is crushed by the impact of the impeller 62 and thrown to the stopper 63 under the action of centrifugal force. The raw material collides with the stopper 63 and is crushed again. The raw material falls downward after colliding with the stopper 63 and falls close to the inner wall of the shell 4 under the action of the baffle 64 until it falls to the bottom of the shell 4 and is discharged by the discharge pipe 612. When the rotating plate 75 rotates to a state with the top surface facing upward, the falling raw material will fall on the upper surface of the rotating plate 75 and fall onto the grinding disc 69 along the rotating plate 75. The rotating shaft 61 rotates together with the shaft sleeve 65 through the bolt 611. The shaft sleeve 65 drives the support shaft 67 and the material roller 68 to revolve around the rotating shaft 61 through the connecting ring 66. The material roller 68 rotates on its own under the friction with the grinding disc 69 while revolving. Therefore, the material roller 68 and the grinding disc 69 can cooperate to grind the raw material to achieve a smaller particle size. The ground raw material falls to the bottom of the shell 4 and is discharged through the discharge pipe 612.

[0058] Example 3, reference Figures 1-12 , as a third embodiment of the present invention, provides: a process based on powder coating production, comprising the following steps:

[0059] S1. First, prepare the required raw materials according to the formula requirements, and add the raw materials into the mixer according to the proportion for thorough mixing. Different types of pigments have different formulas, and corresponding raw materials need to be prepared during production.

[0060] S2. Secondly, the mixed raw materials are melted and extruded through a hot melt extruder to make them into a uniform liquid state. After the raw materials are hot melt mixed, the color is more uniform.

[0061] S3, then, the raw material after hot melt extrusion is divided into small pieces and then put into the hopper 5 of the crusher. The raw material enters the crusher through the hopper 5 and is then crushed into powder by the crushing mechanism 6. During the crushing process, the staff can adjust the crusher to different working modes through the guide mechanism 7 according to actual production needs. The raw material is crushed into fine powder, which is convenient for subsequent coating and curing.

[0062] S4, finally, the powder coating is quality tested, packaged, and then stored under appropriate conditions to ensure stable product quality. Reasonable storage methods are conducive to product preservation.

[0063] S5, the packaged paints of the same batch are stored in a unified warehouse and shipped according to the order. After the production is completed, they are stored in the warehouse or transported to the place where the paint is needed.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
