Description

Technical Field

[0001] This utility model relates to the field of powder spreading machine technology, and in particular to an automatic online glass powder spreading machine. Background Technology

[0002] Applying a release powder during the production of coated glass can prevent two pieces of glass from sticking together too tightly, thus avoiding production accidents. Chinese utility model patent CN210215173U discloses an ultra-durable single-silver Low-E insulating glass powder applicator, including a powder spraying box fixedly mounted on a support and a roller positioned below the powder spraying box. The roller is rotatably connected to the support. The powder spraying box has a powder drop trough on its lower surface, and the roller abuts against the opening of the powder drop trough. The roller includes a solid metal roller in the center and a metal mesh covering the outer surface of the metal roller. This design changes the previous powder spraying machine's use of a powder spray nozzle, resulting in more uniform powder application and a more uniform composition of the release powder. The powder coating box is fixedly mounted on the support frame of the ultra-durable single silver Low-E insulating glass production line. When the roller rotates, the isolation powder inside the powder coating box is sprayed out from the inside of the powder coating box through the slot of the powder drop trough. However, since the slot length of the powder drop trough is different for different powder coating boxes, when the slot of the powder drop trough is long, for glass with a small width, the isolation powder will be sprayed outside the glass surface, resulting in waste of isolation powder. When the slot of the powder drop trough is short, for glass with a large width, the isolation powder cannot be sprayed to all areas of the glass surface, so the versatility is poor. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose an automatic online glass powder spreading machine to solve the technical problem of poor versatility of existing glass powder spreading machines.

[0004] To achieve the above technical objectives, the present invention provides an automatic online glass powdering machine, comprising a conveyor belt for conveying glass and a powdering mechanism installed on the conveyor belt. The powdering mechanism includes a powdering box installed perpendicular to the conveying direction of the conveyor belt, a powdering roller rotatably installed inside the powdering box along its length, and a powdering nozzle provided at the bottom of the powdering roller along its length. The powdering mechanism also includes an adjustment component for adjusting the discharge length of the powdering nozzle. The adjustment component includes baffles slidably disposed at both ends of the powdering nozzle. By moving the two baffles relative to or in opposite directions, the blocking length of the two baffles at both ends of the powdering nozzle can be adjusted, thereby adjusting the discharge length of the powdering nozzle.

[0005] Furthermore, the adjustment assembly also includes a drive unit for driving the two stop bars to move relative to or in opposite directions.

[0006] Furthermore, the drive device includes a transmission screw, which is rotatably mounted on the side wall of the powder-spreading box. The outer walls of both ends of the transmission screw are respectively provided with external threads in opposite directions. Both sets of external threads are threaded with screw nuts. The side walls of the two screw nuts are respectively connected to one end of two connecting blocks. The other ends of the two connecting blocks are respectively connected to the opposite ends of two baffles. A handle is installed on one end of the transmission screw.

[0007] Furthermore, the powder-sprinkling box has strip-shaped holes at both ends of its side wall along its length, and two connecting blocks are slidably disposed inside the two strip-shaped holes respectively.

[0008] Furthermore, both ends of the powder-sprinkling box are provided with through holes, and two baffles are slidably installed inside the two through holes respectively.

[0009] Furthermore, the bottom of the powder dispenser is funnel-shaped.

[0010] Furthermore, the bottom of the powder-spreading box has an arc-shaped structure that matches the curvature of the outer wall of the powder-spreading roller.

[0011] Furthermore, the top of the baffle is an arc-shaped structure that matches the curvature of the outer wall of the powder-spreading roller.

[0012] Furthermore, the side wall of the powder-spreading roller is provided with a mesh groove.

[0013] Furthermore, the conveyor belt is a roller conveyor belt.

[0014] The beneficial effects of this utility model include: 1. The length of the two baffles blocking both ends of the powder spraying nozzle can be adjusted by moving them relative to each other or in opposite directions, thereby adjusting the discharge length of the powder spraying nozzle. Therefore, when applying powder to glass with a narrow width, moving the two baffles relative to each other will reduce the discharge length of the powder spraying nozzle, preventing the powder from being sprayed outside the glass surface and thus avoiding waste of the powder. When applying powder to glass with a wide width, moving the two baffles in opposite directions will increase the discharge length of the powder spraying nozzle, ensuring that the powder is sprayed to all areas of the glass surface. Therefore, it is highly versatile. 2. The transmission screw can be rotated by turning the handle. The transmission screw can drive the two screw nuts to move in opposite directions through two sets of external threads with opposite helical directions. The two screw nuts can drive the two stop bars to move in opposite directions through two connecting blocks, which is convenient for adjustment. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] This utility model embodiment provides an automatic online glass powder spreading machine, such as... Figure 1-3 As shown, the device includes a conveyor belt 1 for conveying glass and a powder-spreading mechanism 2 mounted on the conveyor belt 1. The conveyor belt 1 is a roller conveyor belt. The powder-spreading mechanism 2 includes a powder-spreading box 21 installed perpendicular to the conveying direction of the conveyor belt 1. A powder-spreading roller 22 is rotatably mounted inside the powder-spreading box 21 along its length. The side wall of the powder-spreading roller 22 is provided with a mesh groove. The bottom of the powder-spreading box 21 is provided with a powder-spreading port 211 along its length. The powder-spreading mechanism 2 also includes an adjusting component 23 for adjusting the discharge length of the powder-spreading port 211. The adjusting component 23 includes baffles 231 slidably disposed at both ends of the powder-spreading port 211. The length of the two baffles 231 blocking both ends of the powder dispensing nozzle 211 can be adjusted by moving the two baffles 231 relative to each other or in opposite directions, thereby adjusting the discharge length of the powder dispensing nozzle 211. Therefore, when dispensing powder onto glass with a narrow width, moving the two baffles 231 relative to each other reduces the discharge length of the powder dispensing nozzle 211, preventing the separating powder from being sprinkled outside the glass surface and thus avoiding waste of the separating powder. When dispensing powder onto glass with a wide width, moving the two baffles 231 in opposite directions increases the discharge length of the powder dispensing nozzle 211, allowing the separating powder to be sprinkled onto all areas of the glass surface. Therefore, it has strong versatility.

[0019] It should be noted that the lower end of the powder dispensing box 21 is funnel-shaped, which allows the powder inside the powder dispensing box 21 and the separating powder to be stably dispensed through the powder dispensing port 211 when the powder dispensing roller 22 rotates. At the same time, the bottom of the powder dispensing box 21 is an arc-shaped structure that matches the curvature of the outer wall of the powder dispensing roller 22, and the top of the baffle 231 is an arc-shaped structure that matches the curvature of the outer wall of the powder dispensing roller 22, which can prevent the separating powder from remaining between the powder dispensing roller 22 and the baffle 231.

[0020] It should be noted that both ends of the powder dispensing box 21 are provided with through holes 213, and two baffles 231 are respectively slidably disposed inside the two through holes 213 to ensure stable movement of the baffles 231.

[0021] In this embodiment, the adjusting component 23 further includes a driving device 232, which drives the two baffles 231 to move relative to or in opposite directions. More specifically, the driving device 232 includes a transmission screw 2321, which is rotatably mounted on the side wall of the powder-spreading box 21. The outer walls of both ends of the transmission screw 231 are respectively provided with external threads in opposite directions. Both sets of external threads are threaded with screw nuts 2322. The side walls of the two screw nuts 2322 are respectively connected to one end of two connecting blocks 2323, and the other ends of the two connecting blocks 2323 are respectively connected to the opposite ends of the two baffles 231. One end is equipped with a handle disc 2324. Rotating the handle disc 2324 can drive the transmission screw 2321 to rotate. The transmission screw 2321 can drive two screw nuts 2322 to move relative to or in opposite directions through two sets of external threads with opposite helical directions. The two screw nuts 2322 can drive two stop bars 231 to move relative to or in opposite directions through two connecting blocks 2323 respectively. Adjustment is convenient. In some other embodiments, the handle disc 2324 can be replaced with a drive component such as a motor, hydraulic motor or pneumatic motor that can drive the transmission screw 2321 to rotate automatically, so as to automatically drive the two stop bars 231 to move relative to or in opposite directions, saving manpower.

[0022] It should be noted that both ends of the side wall of the powder box 21 are provided with strip holes 212 along its length. The two connecting blocks 2323 are slidably disposed inside the two strip holes 212 to make the connecting blocks 2323 move stably, thereby making the baffle 231 move stably.

[0023] In this embodiment of the automatic online glass powdering machine, before powdering the glass, the handle 2324 is rotated, which drives the transmission screw 2321 to rotate. The transmission screw 2321 can drive the two screw nuts 2322 to move relative to or in opposite directions through two sets of external threads 23111 with opposite helical directions, thereby adjusting the blocking length of the two baffles 231 at both ends of the powdering port 211. The discharge length of the powdering port 211 can be adjusted according to the width of the glass to be powdered. When the glass is powdered, the powdering roller 22 rotates, so that the isolation powder inside the powdering box 21 is sprinkled out through the powdering port 211 and sprinkled on the glass surface conveyed by the conveyor belt 1.

[0024] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
