Description

Technical Field

[0001] This utility model relates to the field of gypsum powder conveying technology, and in particular to an automatic gypsum powder conveying system. Background Technology

[0002] Gypsum powder is widely used in construction, crafts, agriculture, and other fields. It has environmental protection, moisture regulation, and fire resistance properties. It is mainly divided into: building gypsum powder, used for wall painting, sculpture, etc., with strong adhesion and good sound insulation performance; industrial gypsum powder, including feed additives, cement retarders, and craft model materials, such as dihydrate gypsum and anhydrous gypsum; and edible gypsum powder, such as edible dihydrate gypsum and food additive calcium sulfate, used in food processing and agricultural soil conditioning.

[0003] Shaftless screw conveyors are the main equipment for conveying gypsum powder. They eliminate the central shaft and use a drive source to rotate the screw blades for conveying, which can effectively reduce the probability of blockage. Shaftless screw conveyors are mainly composed of a "U" shaped trough, screw blades and drive mechanism.

[0004] While shaftless screw conveyors have unique advantages in conveying gypsum powder, the upper edge of their "U"-shaped trough is prone to gypsum powder adhesion. After absorbing water, the gypsum powder hardens and adheres to the upper edge of the "U"-shaped trough. Therefore, a new type of automatic gypsum powder conveying system that can easily clean the "U"-shaped trough is needed. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an automatic gypsum powder conveying system that can simulate the reciprocating impact motion of a manual shovel. During the movement of the sliding frame, it can simultaneously and efficiently clean the edges of both sides of the "U"-shaped trough, thereby improving subsequent production quality and efficiency.

[0006] The technical solution adopted to solve the above technical problems is: an automatic gypsum powder conveying system, including a spiral blade, a "U"-shaped groove, a sliding frame, two scrapers and a first spring. The spiral blade is rotatably connected in the "U"-shaped groove, the sliding frame is axially slidably connected to the upper side of the "U"-shaped groove, the two scrapers are slidably connected to both sides of the sliding frame through a first guide rod, and the two scrapers correspond to the two upper edges of the "U"-shaped groove. A first spring is sleeved on the first guide rod, and the scrapers perform scraping operations on the "U"-shaped groove in a bouncing manner.

[0007] Furthermore, it also includes a sliding block, a second spring, a connecting rod, multiple push blocks, and an unlocking rod. The sliding block is slidably connected to the outside of the scraper in a vertical direction. A first inclined surface is opened on one side of the sliding block. The second spring is sleeved on the sliding block. Connecting rods are fixed to both sides of the "U"-shaped groove. Multiple push blocks are equidistantly connected to the connecting rods. The push blocks are used to abut against the plane position of the sliding block and push it to move. A second inclined surface is opened on the side of the push block away from the first inclined surface. When the scraper moves back, the first inclined surface and the second inclined surface cooperate. Unlocking rods are connected to both sides of the sliding frame. The unlocking rods cooperate with the first inclined surface.

[0008] Furthermore, it also includes: the scraper is arranged in a "7" shape, and one side of the scraper is obliquely cut.

[0009] Furthermore, it also includes a second guide rod, with a second guide rod connected to both sides of the "U"-shaped groove. The second guide rod passes through the sliding frame, and the sliding frame is slidably connected to the second guide rod.

[0010] Furthermore, it also includes clearance grooves, with clearance grooves provided on both sides of the sliding frame, and the clearance grooves cooperating with the push block.

[0011] The beneficial effects of this utility model are as follows: By setting a sliding frame above the "U"-shaped groove, when periodically cleaning the gypsum powder at the upper edge of the "U"-shaped groove, the sliding frame is pushed, which drives the scrapers on both sides to move. After the scrapers come into contact with the clumps of gypsum powder, they compress the first spring. After the first spring is compressed to a certain extent, the clumps of gypsum powder are scraped off. At this time, due to the release of the elastic stored energy of the first spring, the scraper bounces forward, which has an impact scraping effect on the gypsum powder behind it, simulating the reciprocating impact action when using a scraper manually. During the movement of the sliding frame, the edges on both sides of the "U"-shaped groove can be cleaned efficiently at the same time, thereby improving the quality and efficiency of subsequent production.

[0018] 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.

[0019] like Figures 1-5 As shown, this embodiment provides an automatic gypsum powder conveying system, including a spiral blade 1, a "U"-shaped groove 2, a sliding frame 3, two scrapers 4, and a first spring 6. The spiral blade 1 is rotatably connected to the "U"-shaped groove 2, the sliding frame 3 is axially slidably connected to the upper side of the "U"-shaped groove 2, and the two scrapers 4 are slidably connected to both sides of the sliding frame 3 through a first guide rod 5. The two scrapers 4 correspond to the two upper edges of the "U"-shaped groove 2, and the first spring 6 is sleeved on the first guide rod 5. The scrapers 4 perform scraping operations on the "U"-shaped groove 2 in a bouncing manner.

[0020] In the above embodiments, by setting a sliding frame 3 above the "U"-shaped groove 2, when periodically cleaning the gypsum powder at the upper edge of the "U"-shaped groove 2, the sliding frame 3 is pushed, which drives the scrapers 4 on both sides to move. After the scrapers 4 come into contact with the gypsum powder clumps, they compress the first spring 6. After the first spring 6 is compressed to a certain extent, the gypsum powder clumps are scraped up. At this time, due to the release of the elastic stored energy of the first spring 6, the scrapers 4 bounce forward, which has an impact scraping effect on the gypsum powder behind, simulating the reciprocating impact action when a scraper is used manually. During the movement of the sliding frame 3, the edges on both sides of the "U"-shaped groove 2 can be cleaned efficiently at the same time, so as to improve the quality and efficiency of subsequent production.

[0021] Specifically, it also includes a sliding block 7, a second spring 9, a connecting rod 10, multiple push blocks 11, and an unlocking rod 13. The sliding block 7 is slidably connected to the outside of the scraper 4 in a vertical direction. A first inclined surface 8 is provided on one side of the sliding block 7. The second spring 9 is sleeved on the sliding block 7. The connecting rod 10 is fixedly connected to both sides of the "U"-shaped groove 2. Multiple push blocks 11 are equidistantly connected to the connecting rod 10. The push blocks 11 are used to abut against the plane position of the sliding block 7 and push it to move. A second inclined surface 12 is provided on the side of the push block 11 away from the first inclined surface 8. When the scraper 4 returns to its original position, the first inclined surface 8 and the second inclined surface 12 cooperate. Unlocking rods 13 are connected to both sides of the sliding frame 3. The unlocking rods 13 cooperate with the first inclined surface 8.

[0022] In the above embodiments, during the process of the sliding frame 3 carrying the scraper 4 forward, the plane of the push block 11 abuts against the plane of the sliding block 7. The push block 11 pushes the sliding block 7, which in turn acts on the scraper 4, causing the scraper 4 to slide relative to the sliding frame 3. The first spring 6 is compressed until the first inclined surface 8 of the sliding block 7 abuts against the unlocking rod 13. The unlocking rod 13 pushes the sliding block 7 upward, causing the sliding block 7 to separate from the push block 11. At this time, the stored energy of the first spring 6 is released, and the scraper 4 bounces forward to clean the gypsum powder on the edge of the "U"-shaped groove 2. Through the above components, the practicality is further improved. Through the active squeezing of the push block 11, the scraper 4 is relatively retracted. The first spring 6 stores energy, so that the bounce of the scraper 4 no longer depends on the gypsum powder clumping, but actively performs energy-storing bounce motion. The scraper 4 performs reciprocating bounce motion throughout its forward movement, performing a bounce impact scraping operation, further improving the cleaning effect and efficiency of the scraper 4.

[0023] Specifically, it also includes: scraper part 4 with a "7" shape setting, and scraper part 4 with a slanted cut on one side.

[0024] In the above embodiments, the scraper 4 is set in a shape similar to the "7" and fits perfectly with the upper edge of the "U" groove 2, which further improves the cleaning effect. After the front side of the scraper 4 is obliquely cut, the front side of the scraper 4 has a better scraping effect.

[0025] Specifically, it also includes a second guide rod 14. The second guide rod 14 is connected to both sides of the "U"-shaped groove 2. The second guide rod 14 passes through the sliding frame 3, and the sliding frame 3 is slidably connected to the second guide rod 14.

[0026] In the above embodiments, the sliding frame 3 slides smoothly via the second guide rods 14 on both sides.

[0027] Specifically, it also includes a relief groove 15. Both sides of the sliding frame 3 are provided with relief grooves 15, which cooperate with the push block 11.

[0028] In the above embodiments, by opening a relief groove 15 on the sliding frame 3, the push block 11 passes through the relief groove 15 when the sliding frame 3 moves, making the overall structure more regular and compact.

[0029] It should be noted that the sliding frame 3 can be slid by manual pushing or by linear electric drive. There are various types of linear electric drive methods available, and any known technology can be used. When using electric drive, it is necessary to ensure dust protection for the drive components and parts.

[0030] The working principle of this utility model is as follows: The gypsum powder on the upper edge of the "U"-shaped groove 2 is cleaned regularly to prevent it from affecting production quality and efficiency. The sliding frame 3 is pushed to slide (electric drive can also be used). The sliding frame 3 moves with the scrapers 4 on both sides. The scrapers 4 are attached to the upper edge of the "U"-shaped groove 2. After the scrapers 4 move forward, the plane position of the sliding block 7 abuts against the plane position of the front push block 11. The push block 11 pushes the sliding block 7 to move relatively backward. The scrapers 4 and the sliding block 7 move relatively backward in sync. The first spring 6 is compressed and stores energy. When the first inclined surface 8 on the sliding block 7 contacts the unlocking rod 13, the unlocking rod 13 causes the sliding block 7 to move upward. The second spring 9 is compressed until the sliding block 7 moves upward and separates from the push block 11. The stored energy of the first spring 6 is released, and the scrapers 4 bounce forward to impact and scrape the gypsum powder clumps on the front side. The bouncing impact operation is repeated during the forward movement of the scrapers 4. After the scraping and cleaning operation is completed, the sliding frame 3 is pushed in the opposite direction. At this time, the first inclined surface 8 of the sliding block 7 contacts and engages with the second inclined surface 12 of the push block 11. The sliding block 7 jumps up and down repeatedly until all parts are reset.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
