Description

Technical Field

[0001] This utility model relates to the field of fireworks production technology, specifically to a batching equipment for fireworks production. Background Technology

[0002] Fireworks production refers to the process of turning raw materials such as pyrotechnics into entertainment products with specific effects through a series of processes. The main components of fireworks and firecrackers include oxidizers and combustibles, which make fireworks and firecrackers extremely dangerous. Therefore, strict safety measures and regulatory systems are required during the production process.

[0003] During fireworks production, workers need to add raw materials to a batching machine for mixing. Currently, some batching machines require internal filters to screen the raw materials. When processing different fireworks, the raw materials and their proportions vary, so workers need to replace the filters to adjust the fineness of the screened raw materials. When replacing the filters, workers need to remove the auxiliary screening scrapers. Currently, some scrapers are connected by bolts, but bolts are prone to stripping during use. Workers need to pay special attention to controlling the tightening force of the bolts. This process is inconvenient to control manually and requires a certain level of expertise from the workers.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6As shown, a batching device for fireworks production includes a batching device body 1, a feed hopper 2 detachably connected to the top of the batching device body 1, and a bracket 3 welded to the surface of the batching device body 1. The connection between the batching device body 1 and the feed hopper 2 is a snap-fit ​​connection, which is a mature existing technology and will not be described in detail here. A motor 4 is fixedly connected to the top of the bracket 3, and a drive shaft 5 rotatably passes through it. The top of the drive shaft 5 is fixedly connected to the output shaft of the motor 4, and a turntable 6 is fixedly connected to the bottom of the drive shaft 5. A storage groove 7 is formed on the surface of the turntable 6. The storage slot 7 is detachably connected to a scraping mechanism 8. The drive shaft 5 is mounted with a covering mechanism 9. The covering mechanism 9 can limit the scraping mechanism 8. The support 3 is slidably fitted with a moving frame 12. The bottom of the moving frame 12 is fixedly connected to a reinforcing frame 13. The surface of the reinforcing frame 13 is provided with a slot 14 and a through slot 15. The top of the moving frame 12 is equipped with a positioning mechanism 16. The top of the support 3 is provided with a positioning groove 17. The positioning mechanism 16 and the positioning groove 17 work together to limit the position of the moving frame 12 and the reinforcing frame 13.

[0024] The scraping mechanism 8 includes a filling plate 81, a vertical rod 82, a connecting frame 83, and a scraper 84. The surfaces of the filling plate 81 and the vertical rod 82 are in contact with the inner wall of the storage tank 7. The vertical rod 82 is fixedly connected to the bottom of the filling plate 81, and the connecting frame 83 is fixedly connected to the bottom of the vertical rod 82. The scraper 84 is detachably connected to the inside of the connecting frame 83. When the turntable 6 rotates, the filling plate 81 placed inside the storage tank 7 rotates accordingly, and the vertical rod 82 can drive the scraper 84 to rotate through the connecting frame 83, thereby assisting in sieving the raw materials at the top of the filter screen in the batching equipment body 1. The filter screen set inside the batching equipment body 1 is a mature existing technology and will not be described in detail here.

[0025] The covering mechanism 9 includes a collar 91, a smooth rod 92, a covering frame 93, and a compression spring 94. The collar 91 is fixedly sleeved on the surface of the drive shaft 5. The two ends of the smooth rod 92 are fixedly connected to the bottom of the collar 91 and the top of the turntable 6, respectively. The covering frame 93 is slidably sleeved on the surface of the smooth rod 92. The inner wall of the covering frame 93 is in contact with the surfaces of the turntable 6 and the filling plate 81. The compression spring 94 is sleeved on the surface of the smooth rod 92. When the operator lifts the covering frame 93, the compression spring 94 is compressed and the covering of the covering frame 93 on the scraping mechanism 8 is released. Then, under the action of the elastic force of the compression spring 94, the covering frame 93 descends and covers the turntable 6, thereby restricting the connection between the scraping mechanism 8 and the turntable 6.

[0026] A slot 10 is provided at the bottom of the inner wall of the cover frame 93. A retaining ring 11 is fixedly fitted on the surface of the turntable 6. The bottom of the retaining ring 11 is higher than the bottom of the turntable 6. The surface of the retaining ring 11 is in contact with the inner wall of the slot 10. The position of the cover frame 93 fitted on the surface of the turntable 6 can be reinforced by the engagement between the slot 10 and the retaining ring 11.

[0027] The positioning mechanism 16 includes a fixed frame 161, a lifting plate 162, a spring 163, and a positioning plate 164. The fixed frame 161 is fixedly connected to the top of the movable frame 12. The surface of the lifting plate 162 is slidably connected to the inner wall of the fixed frame 161. The two ends of the spring 163 are fixedly connected to the top of the inner wall of the fixed frame 161 and the top of the lifting plate 162, respectively. The positioning plate 164 is fixedly connected to the bottom of the lifting plate 162 and contacts the inner wall of the positioning groove 17. The positioning plate 164 slides through the bottom of the fixed frame 161 and the top of the movable frame 12. When the operator pulls the lifting plate 162, the positioning plate 164 can be raised. Then, under the action of the elastic force of the spring 163, the lifting plate 162 drives the positioning plate 164 to descend. The positioning plate 164 cooperates with the positioning groove 17 to fix the position of the movable frame 12.

[0028] Rectangular grooves 18 are provided on both sides of the fixed frame 161, and rectangular plates 19 are fixedly connected to both sides of the lifting plate 162. The surface of the rectangular plate 19 is slidably connected to the inner wall of the rectangular groove 18. The cooperation between the rectangular plate 19 and the rectangular groove 18 can increase the stability of the lifting plate 162 during lifting and moving.

[0029] A baffle 20 is fixedly connected to the surface of the support 3. The surface of the movable frame 12 is in contact with the surface of the baffle 20. By setting the baffle 20, the movement range of the movable frame 12 on the surface of the support 3 can be limited.

[0030] The top of the inner wall of the reinforcing frame 13 contacts the top and bottom of the cover frame 93 respectively, and the bottom of the inner wall of the reinforcing frame 13 contacts the bottom of the turntable 6. Through the cooperation of the reinforcing frame 13, the position of the cover frame 93 can be reinforced to increase the stability of the connection between the scraping mechanism 8 and the turntable 6. The slots 14 and through slots 15 facilitate the normal movement of the reinforcing frame 13.

[0031] Working principle: The operator first pulls the lifting plate 162 upward to move the positioning plate 164 out of the inside of the positioning groove 17 on one side, and then moves the moving frame 12 to the position of the baffle 20. At this time, the positioning plate 164 and the positioning groove 17 on the other side can restrict the moving frame 12. The reinforcement of the cover frame 93 by the reinforcing frame 13 is released, and the operator can lift the cover frame 93 to release the contact between the retaining ring 11 and the retaining groove 10. The compression spring 94 is shortened by force, and the storage groove 7 is exposed to the outside. The operator releases the limit on the feeding hopper 2 and moves the feeding hopper 2 and the scraping mechanism 8. The filling plate 81 is moved out of the inside of the storage groove 7. Based on this, the operator can disassemble the scraping mechanism 8 and the feeding hopper 2 in order to replace the filter screen inside the main body of the batching equipment 1.

[0032] After replacing the filter screen, the staff reinstalls the feed hopper 2 on top of the main body 1 of the batching equipment. Then, the filling plate 81 can be placed inside the storage slot 7. Subsequently, under the action of the compression spring 94, the cover frame 93 descends and covers the turntable 6, thereby restricting the position of the filling plate 81. During this process, the slot 10 and the retaining ring 11 cooperate to reinforce the position of the cover frame 93. Finally, the staff pulls the lifting plate 162 and moves the moving frame 12 so that the position of the cover frame 93 can be reinforced and stabilized by the reinforcing frame 13. Finally, under the action of the spring plate 163, the positioning plate 164 and the positioning slot 17 cooperate to reinforce the position of the reinforcing frame 13, thereby increasing the position reinforcement of the scraping mechanism 8 and the cover mechanism 9.

[0033] When the staff starts the motor 4, the drive shaft 5 drives the turntable 6 to rotate, the filling plate 81 drives the vertical rod 82 to rotate, and the connecting frame 83 drives the scraper 84 to rotate on the surface of the filter screen, thereby assisting the raw material at the top of the filter screen to pass through the screen. The screened raw material falls into the body 1 of the batching equipment to complete the batching and mixing.
