Description

Technical Field

[0001] The utility model relates to the technical field of conductive slurry grinding equipment, in particular to a multi-roller grinding device for conductive slurry production. Background Art

[0002] Conductive paste is a composite material in which conductive powder is dispersed in an organic or inorganic matrix. It includes precious metal powder, base metal powder, glass powder, synthetic resin and other components. After adding solvent, it can be made into a material or graphite-like object. Conductive paste has good conductivity and plasticity, and can be prepared into products in different forms according to needs. When the conductive paste is produced, since the raw materials are in bulk, it is necessary to grind the bulk raw materials. When grinding, it is usually carried out in a corresponding grinding device.

[0003] There are many types of grinding devices on the market, most of which use two grinding rollers to rotate to squeeze and crush the raw materials between the two grinding rollers to complete the grinding operation. However, when using two grinding rollers for grinding, the distance between the two grinding rollers must be small to ensure that the grinding coarseness meets the requirements. In the actual preparation process, large pieces of raw materials cannot be normally stuck between the two grinding rollers for grinding, which further causes large pieces of raw materials to idle on the two grinding rollers, affecting the normal grinding effect and causing inconvenience to users. In view of this, we propose a multi-roller grinding device for conductive paste production. Utility Model Content

[0027] See also Figure 1-Figure 4The utility model provides a technical solution: a multi-roll grinding device for producing conductive slurry, comprising a grinding box 1, a feeding hole 10 is arranged on the top of the grinding box 1, and a plurality of grinding components 2 arranged in a vertical direction and used for grinding operations are arranged inside the grinding box 1. The grinding component 2 comprises two left and right rotating shafts 20 that are symmetrical to each other and rotatably connected to the inner wall of the grinding box 1, and a grinding roller 21 is fixedly mounted on the rotating shaft 20. A gear 22 is fixedly mounted on the same end of the two rotating shafts 20, and the two gears 22 are meshed with each other. A driving motor 23 is coaxially arranged at the end of one of the rotating shafts 20, and the distance between the two grinding rollers 21 facing each other from top to bottom gradually decreases. The gear 22 is located outside the grinding box 1, and the driving motor 23 is fixedly mounted on the outer side of the box body of the grinding box 1 by a plurality of fastening bolts, so as to ensure that when in use, the plurality of grinding rollers 21 can be used to grind the raw materials in sequence from top to bottom, so as to ensure that the grinding is more thorough, and the raw materials will not be difficult to be stuck between the two grinding rollers 21 and ground normally.

[0028] In this embodiment, a plurality of groups of lower inclined baffles 15 for conveying the falling materials toward between the two grinding rollers 21 are fixedly installed on the inner wall of the grinding box 1. The lower inclined baffles 15 are located between the corresponding upper and lower groups of grinding rollers 21. There are two lower inclined baffles 15 in each group, so that the falling raw materials can fall onto the lower inclined baffles 15 and then fall along the lower inclined baffles 15 to between the left and right grinding rollers 21 to be ground more smoothly.

[0029] Specifically, a scraper plate 16 is fixedly installed on the top of the lower inclined baffle plate 15 and is against the bottom cylinder of the grinding roller 21 for scraping operation. The end of the scraper plate 16 contacts the grinding roller 21 so as not to affect the normal rotation of the grinding roller 21. In addition, as the grinding roller 21 rotates, the scraper plate 16 can scrape off the raw materials attached to the grinding roller 21, so that the raw materials can fall along the scraper plate 16 and the lower inclined baffle plate 15 to between the left and right grinding rollers 21 more smoothly.

[0030] In this embodiment, a discharge pipe 17 is fixedly installed on the bottom surface of the two lower inclined baffles 15 at the bottom. The discharge pipe 17 passes through the bottom plate of the grinding box 1 and is connected to the outside, so that the discharge pipe 17 is used for easy discharge operation.

[0031] Specifically, inspection holes 11 connected to the outside are provided on the left and right side surfaces of the grinding box 1, and door panels 12 are hinged on the hole walls of the inspection holes 11 to facilitate opening the door panels 12 for inspection operations; a plurality of support legs 13 arranged in a matrix are fixedly installed on the bottom surface of the grinding box 1, and the support legs 13 are used for stable support operations.

[0032] Furthermore, two symmetrical upper material baffle plates 14 are fixedly installed on the top wall of the grinding box 1. The upper material baffle plates 14 are located above the two uppermost grinding rollers 21, and are used for the raw materials to fall along the upper material baffle plates 14 to fall between the two grinding rollers 21, making the raw materials fall from top to bottom between the two grinding rollers 21 more smoothly.

[0033] In addition, a feed hopper 3 is fixedly mounted on the hole wall of the feed hole 10 , and the feed hopper 3 is used for feeding operation.

[0034] It is worth mentioning that upper support plates 30 are fixedly installed on the inner walls on both sides of the top of the feed hopper 3, and sealing plates 31 are hinged on the left and right side plates of the feed hopper 3. The sealing plates 31 are located below the upper support plate 30. Fixed rings 32 are fixedly installed on the upper surface of the sealing plate 31 and the bottom surface of the upper support plate 30. A tension spring 33 is arranged between the two fixing rings 32. The two sealing plates 31 are closed to reduce dust from flying outward. In addition, as raw materials are added, the raw materials accumulate on the sealing plates 31, the gravity on the sealing plates 31 increases, and the sealing plates 31 will rotate downward. At this time, there is a gap between the two sealing plates 31 for the raw materials to fall, so that the raw materials can fall normally.

[0035] When the multi-roller grinding device for conductive paste production of the utility model is in use, raw materials are added into the feed hopper 3, and the raw materials fall down along the gap between the two blocking plates 31 after opening. The drive motor 23 is connected to an external power source and made to work. When the drive motor 23 works, the output shaft thereon rotates to drive the rotating shaft 20 to rotate. Since the two gears 22 are meshed with each other, the two rotating shafts 20 and the two grinding rollers 21 can be driven to rotate synchronously. After the raw materials fall between the two grinding rollers 21, the grinding rollers 21 rotate, so that the raw materials between the two grinding rollers 21 can be ground, and the ground powder can be discharged outward along the discharge pipe 17.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
