Description

Technical Field

[0001] The invention relates to the technical field of mortar grinding, in particular to a grinding machine for producing premixed mortar. Background Art

[0002] During the construction and production of buildings, component surfaces and base materials, mortar is applied to their surfaces as a protective material for the base. This mortar, which both protects the base and meets the requirements of use, is collectively referred to as plastering mortar.

[0003] For example, a dry mortar grinding device for water-based paint processing with publication number CN113713904A feeds dry mortar into the cylinder through a feed pipe, and then the motor rotates clockwise to drive the left worm to rotate, and then the transmission gear on the side of the left worm drives the right worm to rotate to pre-crush the dry mortar fed into the cylinder, so as to avoid the device directly grinding the dry mortar block through the grinding block, resulting in a large load on the grinding block, which can easily affect the service life of the device. However, in actual use, the raw materials are fed through a feed pipe, and the position of the feed pipe is relatively fixed. The raw materials can only be fed at a fixed point. In the subsequent grinding process, the raw materials are unevenly fed and easily accumulate on the worm, which will affect the grinding quality. Moreover, the worm can only grind the raw materials in a designated area due to uneven feeding, which reduces the service life of the worm. There are certain defects in use.

[0004] Therefore, we propose a grinding machine for the production of premixed mortar to solve the above problems. Summary of the invention

[0027] Compared with the prior art, the invention has the following beneficial effects: the grinding machine for premixed mortar production is provided with grinding components inside and outside the box, so that when grinding dry mortar, the material can be fed evenly to avoid accumulation, avoid affecting normal grinding, and increase the service life of the grinding roller shaft. During grinding, the dust generated at the material feeding place can be adsorbed to avoid dust dispersion and pollution of the working environment.

[0028] 1. Grinding components are arranged inside and outside the box. When grinding dry mortar, the raw materials are put into the feed pipe, and the driving motor is started to drive the left front rotating shaft to rotate, so that the front grinding roller shaft rotates. The two grinding roller shafts rotate relatively through the meshing of two connecting gears. The raw materials in the feed pipe can be thrown between the two grinding roller shafts through the bellows and the discharge pipe. When the driving motor is running, the reciprocating screw rod can be driven to rotate through the cooperation of the active pulley and the first pulley. After the reciprocating screw rod rotates, the discharge pipe is driven to move back and forth continuously through the movable sleeve, so that the material can be discharged evenly. When the two active pulleys rotate, the second pulley can be driven to rotate through the belt, so that the rotating rod can be driven to rotate on the dust cover. The rotating blades rotate, and the reciprocating movement of the discharge pipe can drive the two air intake hoods to reciprocate through the mounting plate. The rotation of the rotating blades can absorb the dust generated by the discharge through the telescopic hose and the air intake hood, and discharge it through the connecting pipe. The two connecting pipes can be connected to the breathable dust collecting bag to collect the dust. While the material is discharged evenly, the two air intake hoods can move together with the discharge pipe, so that the dust generated by the raw material discharge can always be absorbed. The grinding component allows the dry mortar to be fed evenly to avoid accumulation, avoid affecting normal grinding, and increase the service life of the grinding roller. While grinding, the dust generated at the discharge can be absorbed to avoid dust dispersion and pollution of the working environment.

[0029] 2. When the mounting plate drives the air intake hood to move back and forth, it can drive the sliding rod to move. After the sliding rod moves, the roller can rotate on the convex block, and then the sliding rod can be pushed to slide on the mounting frame. After the sliding rod moves, the telescopic spring can be stretched, and the movable rod can be driven to slide on the support frame. After the movable rod moves, the gear can be driven by the rack to rotate, so that the connecting rod can rotate. After the connecting rod rotates, the air intake hood can be driven to rotate. With the movement of the mounting plate, the sliding rod can move back and forth, and then the connecting rod can drive the air intake hood to swing back and forth, which can expand the adsorption range of the air intake hood, improve the dust removal effect, avoid uneven adsorption after dust dispersion during grinding, fully adsorb the dust, and improve practicality;

[0030] 3. While the driving motor is running, the connecting shaft can be driven to rotate through the cooperation of the active pulley and the third pulley. After the connecting shaft rotates, the engagement of the first bevel gear and the second bevel gear can drive the rotating shaft to rotate on the positioning frame, so that the conical grinding head rotates. After being ground by the grinding roller shaft, the raw material will fall into the inside of the conical shell. Then, the rotation of the conical grinding head can further grind the raw material and improve the grinding quality. BRIEF DESCRIPTION OF THE DRAWINGS

The two connecting pipes 215 can be connected to the breathable dust collection bag to collect the dust. While the feeding is uniformly discharged, the two air inlet covers 220 can move together with the feeding pipe 213, so that the dust generated by the raw material feeding can always be absorbed;

[0059] When the mounting plate 221 drives the air intake hood 220 to move back and forth, the sliding rod 228 can be driven to move. After the sliding rod 228 moves, the roller 233 can rotate on the protrusion 232, and then the sliding rod 228 can be pushed to slide on the mounting frame 227. After the sliding rod 228 moves, the telescopic spring 229 can be stretched, and the movable rod 225 can be driven to slide on the support frame 224. After the movable rod 225 moves, the rotating gear 223 can be driven to rotate through the rack 226, so that the connecting rod 222 can rotate. After the connecting rod 222 rotates, the air intake hood 220 can be driven to rotate. As the mounting plate 221 moves, the sliding rod 228 can move back and forth. The connecting rod 222 can move back and forth to drive the air intake hood 220 to swing back and forth, thereby expanding the adsorption range of the air intake hood 220. While the driving motor 202 is running, the connecting shaft 238 can be driven to rotate through the cooperation of the active pulley 206 and the third pulley 239. After the connecting shaft 238 rotates, the engagement of the first bevel gear 240 and the second bevel gear 241 can drive the rotating shaft 235 to rotate on the positioning frame 234, so that the conical grinding head 236 rotates. After being ground by the grinding roller shaft 203, the raw material will fall into the inside of the conical shell 102. Then, the rotation of the conical grinding head 236 can further grind the raw material to improve the grinding quality.
