Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a grinding equipment for silicone sealant raw materials for glass curtain walls. Background Technology

[0002] The raw material system of silicone sealant mainly includes basic polymers, crosslinking agents, fillers, and functional additives. The basic polymers include hydroxyl-terminated polydimethylsiloxane and alkoxy-terminated polydimethylsiloxane. The crosslinking agents include acetic acid type, ketoxime type, amino type, or alkoxysilane oligomers. The fillers include nano-calcium carbonate and silica. The functional additives include organotin compounds or organotitanium compounds, dimethyl silicone oil, aminosilane, alkoxysilane, ultraviolet absorbers or antioxidants, carbon black, etc. There are various types of grinding equipment for silicone sealant raw materials. Its core function is to crush the material to the target fineness through physical action, such as impact, friction, and shearing.

[0003] Early base material grinding relied on manual operation, resulting in low grinding efficiency and uneven fineness, which could not meet the fine particle size requirements of silicone sealant. Although some equipment was equipped with sieve plates, it did not combine with vibration auxiliary mechanism, resulting in low sieving efficiency and easy sieve hole blockage. Furthermore, materials that were not ground to the size that could be sieved could not be processed in time, which could easily lead to blockage, affecting production continuity and efficiency. In addition, traditional grinding equipment uses a single grinding structure, which makes it difficult to achieve multiple crushing of materials, and the problem of uneven particle size distribution still exists. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grinding device for silicone sealant raw materials used in glass curtain walls.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A grinding device for silicone sealant raw materials for glass curtain walls includes a housing and a feeding port fixedly installed on the upper side of the housing. A motor is fixedly connected to the outer wall of the housing. A first grinding roller and a second grinding roller rotatably pass through the inside of the housing. A first gear and a second gear are fixedly connected to the same side of the first grinding roller and the second grinding roller, respectively, and the first gear and the second gear mesh. A first pulley is drivenly connected to one side of the first grinding roller and the output end of the motor. A fixed rod is fixedly connected to one side of the housing. A rotating shaft passes through one end of the fixed rod. A second pulley is drivenly connected to one end of the rotating shaft and the side of the second grinding roller. A cam is fixedly connected to the rotating shaft. A screen plate is slidably connected to the inner wall of the housing. A spring is fixedly connected between the screen plate and the housing. A convex plate is fixedly connected to one side of the screen plate. The convex plate passes through the housing and is opposite to the cam.

[0007] Preferably, a slide rail is fixedly connected to the inner wall of the outer shell, and connecting rods are rotatably connected to both sides of the sieve plate. A slide rod is rotatably passed through one end of the connecting rod, and a long shovel is fixedly connected to the slide rod. The two ends of the slide rod are slidably connected to the slide rail.

[0008] Preferably, a rotary blade is fixedly connected to the output end of the motor.

[0009] Preferably, a discharge port is provided on the lower side of the outer casing.

[0010] Preferably, a plurality of support pillars are fixedly connected to the lower side of the outer casing.

[0011] Preferably, a triangular block is fixedly connected inside the outer shell, and a protruding strip is fixedly connected to the upper end of the triangular block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model is equipped with a sieve plate, and the sieve plate is repeatedly abutted by the rotation of the cam. With the help of the spring and the convex strip, the sieve plate swings in both vertical and horizontal directions, which improves the screening rate, prevents the sieve plate from clogging, and improves the continuity and efficiency of production.

[0014] 2. This utility model uses the movement of the sieve plate to drive the long shovel to move up and down repeatedly along the slide rail, which processes the material that has not been effectively ground and has accumulated on the sieve plate. This allows the incompletely ground material to return to the grinding roller for further grinding, and it also promptly addresses the blockage of the sieve holes in the sieve plate, thereby improving production efficiency and production continuity.

[0015] 3. Furthermore, by utilizing two grinding structures, a rotary cutter and a grinding roller, the material is subjected to multiple crushing processes, which improves grinding efficiency and thus enhances overall production efficiency. Attached Figure Description

[0021] Reference Figures 1-4 A grinding device for silicone sealant raw materials used in glass curtain walls includes a housing 1 and a feeding port 3 fixedly installed on the upper side of the housing. The feeding port 3 is a funnel-shaped structure for easy material loading. Multiple support columns 4 are fixedly connected to the lower side of the housing 1, and multiple shock-absorbing pads are fixedly installed on the lower side of the support columns 4. These pads not only provide support for the support columns 4 but also reduce vibration and adverse effects on other working objects when the housing 1 is in operation. A discharge port 8 is provided on the lower side of the housing 1, and a push-pull sliding plate is provided on the discharge port 8. During non-production operations... The discharge port 8 can be closed by pushing and pulling the sliding plate to prevent contaminants from entering and affecting the purity of the product. A motor 2 is fixedly connected to the outer wall of the outer shell 1, and a rotating blade 7 is fixedly connected to the output end of the motor 2. The rotating blade 7 rotates and passes through the inner side of the outer shell 1, and can grind the material a second time to achieve the fineness required for production. A first grinding roller 9 and a second grinding roller 10 rotate through the inner side of the outer shell 1. A first gear 17 and a second gear 16 are fixedly connected to the same side of the first grinding roller 9 and the second grinding roller 10, respectively. The first gear 17 and the second gear 16 mesh. A first pulley 5 is connected to one side of the first grinding roller 9 and the output end of the motor 2. A fixed rod 11 is fixedly connected to one side of the outer casing 1. One end of the fixed rod 11 rotatably passes through a rotating shaft 14. One end of the rotating shaft 14 is connected to one side of the second grinding roller 10 via a second pulley 6. A cam 12 is fixedly connected to the rotating shaft 14. A sieve plate 18 is slidably connected to the inner wall of the outer casing 1. Multiple springs 15 are fixedly connected between the sieve plate 18 and the outer casing 1. A convex plate 13 is fixedly connected to one side of the sieve plate 18. The convex plate 13 passes through the outer casing 1 and is opposite to the cam 12. The rotation repeatedly abuts the screen plate, and under the action of the spring 15, the screen plate 18 swings in the horizontal direction. A triangular block 24 is fixedly connected inside the outer shell 1, and a protrusion 23 is fixedly connected to the upper end of the triangular block 24. When the screen plate 18 swings horizontally, it abuts against the protrusion 23, causing the screen plate 18 to swing in the vertical direction. A slide rail 20 is fixedly connected to the inner wall of the outer shell 1. A connecting rod 19 is rotatably connected to both sides of the screen plate 18. A slide rod 21 is rotatably passed through one end of the connecting rod 19. A long shovel 22 is fixedly connected to the slide rod 21. The two ends of the slide rod 21 are slidably connected to the slide rail 20.

[0022] In this invention, when it is necessary to grind the silicone sealant raw material for glass curtain walls, the material is added through the feeding port 3, and the motor 2 is started simultaneously. The first belt pulley 5 drives the first gear 17 to rotate, which in turn drives the second gear 16 to rotate relative to it. This causes the first grinding roller 9 and the second grinding roller 10 to rotate relative to each other, performing preliminary grinding on the material. The ground material falls onto the screen plate 18. Under the transmission of the second belt pulley 6, the rotating shaft 14 rotates, causing the cam 12 to rotate and continuously abut against the convex plate 13. With the cooperation of the spring 15 and the convex strip 23, the screen plate 18 is driven to sway in both vertical and horizontal directions, raising the screen plate. The sieve pass rate of 18 helps prevent clogging to some extent. When the material is larger than the aperture of the sieve plate 18, some material accumulates on the sieve plate 18. Under the horizontal shaking of the sieve plate 18, the connecting rod 19 drives the sliding rod 21 to move up and down along the slide rail 19, thereby driving the long shovel 22 to clean up the material accumulation that is larger than the aperture of the sieve plate 18, so that the material returns to the first grinding roller 9 and the second grinding roller 10 for further grinding. The material that passes through the sieve hole of the sieve plate 18 slides on the triangular block 24 to the rotating knife 7. The rotating knife 7 performs secondary grinding on the material and finally discharges it from the discharge port 8, thus completing the grinding of the silicone rubber raw material.
