Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a material feeding device for coating production. Background Art

[0002] Paint is applied to the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the coated object. It is usually a viscous liquid made of resin, oil, or emulsion, with corresponding additives added, and organic solvents or water. A lot of powder materials need to be added during the paint production process.

[0003] At present, it is necessary to feed and quickly discharge powdered raw materials during the production and processing of coatings. However, the traditional material feeding device is not equipped with a more effective screening mechanism or crushing mechanism, which makes it impossible to effectively isolate or crush some larger particles and agglomerated materials in the raw materials, which can easily cause blockage of the discharge port, thereby affecting the use effect of the device. In addition, large particles and agglomerated materials are prone to insufficient mixing when entering the production link, thus affecting the efficiency and quality of coating production. Summary of the invention

[0004] The purpose of the utility model is to provide a material feeding device for coating production which has screening and crushing functions and high feeding efficiency in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A material feeding device for paint production is characterized in that it includes a feeding barrel and a lower hopper, the feeding barrel is a rectangular cylinder with openings at both ends, the upper end of the lower hopper matches the feeding barrel and the lower end of the feeding barrel is fixedly connected to the upper end of the lower hopper, the lower port diameter of the lower hopper is smaller than the upper port diameter, a filter screen is arranged in the feeding barrel, the filter screen is horizontally fixedly connected to the middle part of the feeding barrel, a rolling mechanism is arranged above the filter screen, the rolling mechanism can roll back and forth the material located on the upper surface of the filter screen, and a beating mechanism that can flexibly beat the filter screen is arranged below the filter screen.

[0007] When the material feeding device for coating production is in use, the powder raw material is added into the feeding cylinder from the top of the feeding cylinder. After the filtering and screening effect of the filter screen in the feeding cylinder, the agglomerated materials are blocked on the upper layer of the filter screen. The rolling mechanism can roll back and forth on the upper surface of the filter screen, so that the rolling mechanism rolls and crushes the agglomerated materials on the upper layer of the filter screen, so that the materials are in powder form and enter the feeding cylinder under the filter screen through the filter screen. The feeding cylinder is connected with the lower hopper below, so that the materials enter the lower hopper through the feeding cylinder and are output from the lower end of the lower hopper. The lower hopper is usually arranged in the coating production device. , so the material output from the lower hopper can directly enter the subsequent coating production process. In addition, during the material feeding process, the beating mechanism arranged under the filter can beat the filter, thereby promoting the powdered material to pass through the filter and be output through the lower hopper, avoiding the material from clogging the mesh of the filter and affecting the feeding effect. The contact point between the beating mechanism and the filter is a flexible material, and the flexible contact is achieved when beating the filter, avoiding the beating mechanism from damaging the filter or causing the filter to move up and down, thereby ensuring that the rolling mechanism can stably perform the rolling and crushing work on the filter.

[0008] In the above-mentioned material feeding device for paint production, the rolling mechanism includes a cylinder, a connecting piece, and a rolling roller. The cylinder is fixedly connected to the outer surface of the left side of the feeding barrel, and the piston rod of the cylinder penetrates the side wall of the feeding barrel and extends into the feeding barrel. The connecting piece is "U"-shaped when viewed from above, and the midpoint of the inner end of the connecting piece is fixedly connected to the end of the piston rod of the cylinder. The rolling roller rests on the upper surface of the filter screen, and the end of the rolling roller is axially fixed to the outer end of the connecting piece and the rolling roller can rotate circumferentially.

[0009] The structure of the connecting piece makes the rolling roller axially fixed and able to rotate circumferentially. At the same time, the connecting piece is connected to the piston rod of the cylinder, and the rolling roller rests on the surface of the filter screen. Driven by the cylinder, the rolling roller can always fit the filter screen and crush the agglomerated materials on the filter screen until the agglomerated materials become powder and pass through the filter screen into the feeding hopper below, and finally are transported from the lower end of the feeding hopper to the paint production equipment for paint production.

[0010] In the above-mentioned material delivery device for paint production, the connecting part is composed of a connecting rod and two connecting arms, the inner ends of the two connecting arms are respectively vertically fixed at the two ends of the connecting rod and the two connecting arms are located on the same side of the connecting rod, the outer ends of the two connecting arms are respectively connected to the two ends of the rolling roller, and the other side of the connecting rod is fixedly connected to the piston rod of the cylinder and the connection between the two is located at the midpoint of the connecting rod.

[0011] The "U"-shaped structure formed by the connecting rod and the connecting arm has high structural stability. The connecting rod is used to connect to the cylinder and fix the connecting arm. The connecting arm is used to connect the two ends of the rolling roller, so that the rolling roller is axially fixed and can rotate circumferentially. Therefore, under the drive of the cylinder, the rolling roller can stably perform the rolling work and crush the agglomerated materials blocked on the filter screen into powder.

[0012] In the above-mentioned material delivery device for coating production, both ends of the rolling roller are provided with protruding connection columns, and the outer ends of the two connection arms are respectively connected to the connection columns at both ends of the rolling roller.

[0013] The arrangement of the connecting column facilitates the connection between the connecting arm and the rolling roller, so that the rolling roller can rotate in a circumferential direction to roll and crush the materials on the filter screen.

[0014] In the above-mentioned material feeding device for paint production, the beating mechanism includes a motor, a beating roller and a beating blade. The motor is fixedly connected to the outer surface of the front side of the feeding barrel, and the output shaft of the motor extends into the feeding barrel and is fixedly connected to the beating roller. The outer surface of the beating roller is fixedly connected with a beating blade. Under the drive of the motor, the beating blade can act on the lower surface of the filter.

[0015] When the beating mechanism is running, the motor drives the beating roller to rotate circumferentially, so that the beating blades fixed to the outer surface of the beating roller can intermittently beat the lower surface of the filter screen, promoting the powdered material to pass through the filter screen, improving the efficiency of material discharge, and avoiding the material clogging the mesh of the filter screen and affecting the effect of material discharge.

[0016] In the above-mentioned material feeding device for coating production, there are several beating blades, and the several beating blades are evenly distributed around the circumference of the beating roller.

[0017] A plurality of beating blades can effectively improve the beating efficiency, so that the beating mechanism can continuously beat the filter screen under the drive of the motor, thereby further improving the feeding efficiency.

[0018] In the above-mentioned material feeding device for coating production, the flapping blades are made of flexible rubber material.

[0019] The beating blades are made of flexible rubber material, so that the beating blades can flexibly contact the filter screen when the beating mechanism is running, avoiding damage to the filter screen or causing the filter screen to shift up and down and affect the stability of the rolling roller, ensuring that the rolling roller can stably and continuously crush the agglomerated materials on the filter screen.

[0020] The material feeding device for coating production further includes a mounting frame, which is fixedly connected to the outer surface of the left side of the feeding barrel, and the cylinder is fixedly connected to the mounting frame.

[0021] The setting of the mounting frame enables the cylinder to be stably connected to the feeding barrel, thereby ensuring the working stability of the rolling mechanism.

[0022] In the above-mentioned material feeding device for coating production, the lower end of the feeding barrel has a flange plate 1, and the upper end of the lower hopper has a flange plate 2. The flange plate 1 and the flange plate 2 match and are connected by fasteners.

[0023] The provision of flange one and flange two increases the contact area between the feeding barrel and the lower hopper, and the two are connected by fasteners, the number of which is several, so that the connection between the feeding barrel and the lower hopper is more stable and easy to disassemble, thereby facilitating the cleaning of the feeding barrel and the lower hopper and facilitating the maintenance of the filter screen and the beating mechanism.

[0024] In the above-mentioned material feeding device for coating production, there are two groups of the rolling mechanism and the mounting frame, and the two groups of the rolling mechanism and the mounting frame are symmetrically arranged on the left and right sides of the feeding barrel.

[0025] Two sets of rolling mechanisms and mounting frames are symmetrically arranged on both sides of the feeding barrel, so that the two sets of rolling mechanisms can work simultaneously, effectively improving the efficiency of rolling and crushing the agglomerated materials blocked on the filter screen, thereby further improving the efficiency of material feeding and making the efficiency and quality of subsequent coating production processes higher.

[0026] Compared with the prior art, the material feeding device for paint production has the function of screening materials by setting a filter screen, and has the function of crushing materials by setting a second rolling mechanism, so that the agglomerated materials in the powder raw materials of paint production can be filtered and crushed, so that the materials can be fed into the paint production equipment in powder form, thereby ensuring the quality of paint production; and the setting of the pattering mechanism can promote the powdered materials to pass through the filter screen and be output from the lower hopper, the filter screen is not easily blocked by the materials, and the feeding effect is better, thereby further improving the efficiency of material feeding and making the subsequent paint production more efficient; in addition, the feeding barrel and the lower hopper are connected by flange one, flange two and fasteners, the connection is stable and easy to disassemble, thereby facilitating the cleaning and maintenance of the device and being easy to use.
