Description

Technical Field

[0001] This utility model relates to the field of mineral wool board processing technology, specifically to an automatic material distribution device for mineral wool boards. Background Technology

[0002] Mineral wool board, also known as mineral wool decorative sound-absorbing board, is a new type of board material made from mineral fiber wool as the main raw material, with appropriate additives, and processed through processes such as batching, molding, drying, cutting, embossing, and finishing. It has superior properties such as sound absorption, non-combustibility, heat insulation, and decoration, and is therefore widely used in various indoor ceilings.

[0003] Currently, in the batching process of mineral wool boards, the treated fiber raw materials are usually added to a mixing device along with binders, thickeners, dispersants, and flocculants, and an appropriate amount of water is added for mixing to form a mineral wool slurry. However, in actual operation, the fiber raw materials and various raw materials such as binders, thickeners, dispersants, and flocculants are usually added to the mixing device together in a spreading manner. Although this can shorten the spreading time, a large amount of raw materials are mixed together, which requires a long time to achieve a uniform mixing effect. As a result, production efficiency cannot be improved. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic material distribution device for mineral wool boards, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: an automatic material distribution device for mineral wool board, including a mixing box, a support frame installed at the bottom of the mixing box, a discharge valve pipe, and a water inlet pipe installed at the top of the mixing box. Both sides of the top of the mixing box are equipped with feeding boxes that communicate with its own space, and a feeding curved pipe is fitted on one side of the top of the feeding box.

[0006] The mixing tank is internally fitted with a first drive shaft and several first stirring rods, and the several first stirring rods are arranged at equal intervals along the circumference of the first drive shaft. The top structure of the first drive shaft penetrates the top structure of the mixing tank and is connected to a servo motor installed on the top surface of the mixing tank.

[0007] Both feeding boxes have a sloping arc discharge groove at the bottom, and both feeding boxes have a second drive shaft installed inside through a bearing. The bottom end of the second drive shaft passes through the sloping arc discharge groove and is equipped with a discharge baffle that can cover and seal the sloping arc discharge groove.

[0008] The tops of the two second drive shafts pass through the top structure of their respective feeding boxes and are connected to second gears. The output end of the servo motor is connected to a first gear that can mesh synchronously with the two second gears.

[0009] In particular, the open port surface of the feeding tube is provided with external threads and a sealing cap is screwed in by the external threads, thereby ensuring the sealing of the feeding box during use.

[0010] Specifically, the top end of the first drive shaft is connected to the output end of the servo motor, and the top structure of the first drive shaft is fitted with the top structure of the mixing tank through bearings, thereby improving the rotational stability of the first drive shaft.

[0011] The selected design features several second stirring rods mounted on the surfaces of both second drive shafts to enhance the stirring effect and prevent unused raw materials from caking. Additionally, spiral blades are mounted on the bottom of both second drive shafts.

[0012] Preferably, the spiral blade can rotate synchronously with the second drive shaft, and the rotation output direction of the spiral blade is towards the bottom port space of the corresponding feeding box. The spiral blade, in conjunction with the second drive shaft, conveys and prevents blockage in the bottom space of the feeding box.

[0013] The discharge baffle consists of an adjusting plate and a rubber sealing gasket fixed to the top surface of the adjusting plate. The flexible contact and rigid support between the discharge baffle and the feeding box can fully ensure smooth discharge output from the feeding box while ensuring a sealing effect on the inferior arc discharge trough. The middle part of the adjusting plate is fixedly sleeved with the bottom end of the corresponding second drive shaft. The overall structure of the discharge baffle is an inferior arc structure.

[0014] The bottom structure of the mixing tank is conical, which facilitates subsequent material discharge and reduces the amount of residual raw materials. The length of several first stirring rods located in the bottom space of the mixing tank decreases sequentially along the inclined direction of the conical structure at the bottom of the water inlet pipe, ensuring that the mixing effect can provide an extended use effect for auxiliary material discharge.

[0015] The support frame has several clearance grooves inside, which ensures the structural strength of the support frame while reducing its structural weight. The top inner side of the support frame is fixedly sleeved with the bottom structure of the mixing tank, and a reinforcing ring plate is fixedly sleeved on the bottom inner side of the support frame to improve the structural strength of the support frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model consists of a feeding box, a slightly curved discharge chute at the bottom of the feeding box, a second drive shaft, and a discharge baffle, forming a multi-functional feeding device. Subsequently, the two multi-functional feeding devices are combined with a servo motor, a first drive shaft, a stirring mechanism consisting of multiple first stirring rods on the first drive shaft, a first gear, and a meshing transmission mechanism consisting of two second gears. This allows for the automatic and uniform mixing of various materials entering the mixing box while periodically feeding materials into the mixing box, thus fully solving the problems existing in the prior art.

[0018] 2. This utility model, through the linkage of the spiral blades and multiple second stirring rods with the second drive shaft, can avoid the blockage of the material output and distribution inside the feeding box and automatically stir and disperse the material inside the feeding box after rotating synchronously with the second drive shaft, thus fully optimizing the overall performance of the device.

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1-5 An automatic material distribution device for mineral wool board includes a mixing tank 1, a support frame 2 installed at the bottom of the mixing tank 1, a discharge valve pipe 3, and a water inlet pipe 4 installed at the top of the mixing tank 1. Both sides of the top of the mixing tank 1 are equipped with feeding boxes 6 that communicate with its own space. A feeding curved pipe 8 is fitted on one side of the top of the feeding box 6. The open port surface of the feeding curved pipe 8 is provided with external threads and a sealing cap is screwed on by the external threads, thereby ensuring the sealing of the feeding box 6 during use.

[0028] The mixing tank 1 is internally fitted with a first drive shaft 7 and several first stirring rods 14, and the several first stirring rods 14 are arranged at equal intervals along the circumference of the first drive shaft 7. The top structure of the first drive shaft 7 penetrates the top structure of the mixing tank 1 and is connected to a servo motor 5 installed on the top surface of the mixing tank 1. The top end of the first drive shaft 7 is connected to the output end of the servo motor 5. The top structure of the first drive shaft 7 is fitted with the top structure of the mixing tank 1 through a bearing to improve the rotational stability of the first drive shaft 7.

[0029] Both feeding boxes 6 have a slightly curved discharge chute 9 at their bottom, and both feeding boxes 6 have a second drive shaft 10 mounted inside them via bearings. The bottom end of the second drive shaft 10 passes through the slightly curved discharge chute 9 and is fitted with a discharge baffle 11 that can cover and seal the slightly curved discharge chute 9. The discharge baffle 11 consists of an adjusting plate and a rubber sealing gasket fixed to the top surface of the adjusting plate. The flexible contact and rigid support between the discharge baffle 11 and the feeding box 6 can fully ensure smooth discharge of material from the feeding box 6 while ensuring a sealing effect on the slightly curved discharge chute 9. The middle part of the adjusting plate is fixedly sleeved with the bottom end of the corresponding second drive shaft 10. The discharge baffle 11 has a slightly curved structure. The tops of the two second drive shafts 10 pass through the top structure of their respective feeding boxes 6 and are connected to a second gear 13. The output end of the servo motor 5 is connected to a first gear 12 that can mesh synchronously with the two second gears 13.

[0030] In use, fiber raw materials and mixing reagents are added into the two feeding boxes 6 through two feeding curved pipes 8. Then, the two sealing covers are reset and locked. After completion, the servo motor 5 is started. The output end of the servo motor 5 drives the first drive shaft 7, the multiple first stirring rods 14 and the first gear 12 set on the first drive shaft 7 to rotate synchronously. Then, the rotating first gear 12 will mesh with the two second gears 13 synchronously, which in turn drives the two second gears 13 to drive their respective second drive shafts 10 and discharge baffles 11 to rotate synchronously. Then, by utilizing the overlapping and sealing effect of the two discharge baffles 11 and their respective inferior arc discharge grooves 9, the fiber raw materials and mixing reagents placed in the two feeding boxes 6 will enter the mixing box 1 in a periodic feeding manner. At the same time, the first drive shaft 7 and the multiple first stirring rods 14 will synchronously stir and mix the fiber raw materials and mixing reagents entering the mixing box 1. This process is repeated, so as to achieve uniform stirring while periodically feeding the materials, which fully solves the problems existing in the prior art.

[0031] Please see Figure 1 , Figure 6 Each of the two second drive shafts 10 has several second stirring rods 15 installed on its surface to increase the stirring effect and prevent unused raw materials from caking. Both of the two second drive shafts 10 have spiral blades 16 installed at their bottoms. The spiral blades 16 can rotate synchronously with the second drive shafts 10, and the rotation output direction of the spiral blades 16 is towards the bottom port space of the corresponding feeding box 6. The spiral blades 16, in conjunction with the second drive shafts 10, convey and prevent blockage of the bottom space of the feeding box 6.

[0032] When in use, considering the long material feeding time inside the two feeding boxes 6, multiple second stirring rods 15 are set up and divided into two groups to rotate synchronously with the two second drive shafts 10, thereby synchronously stirring the material inside the two feeding boxes 6 to avoid material caking.

[0033] Meanwhile, to prevent the two feeding boxes 6 from getting blocked during the feeding process, two spiral blades 16 are used to drive the two second drive shafts 10 to output spirals and prevent blockage.

[0034] Please see Figure 1The bottom structure of the mixing tank 1 is conical, which facilitates subsequent material discharge and reduces the amount of residual raw materials. The length of several first stirring rods 14 located in the bottom space of the mixing tank 1 decreases sequentially along the inclined direction of the conical structure at the bottom of the water inlet pipe 4, ensuring that the mixing effect can provide an extended use effect for auxiliary material discharge. Several clearance grooves are opened inside the support frame 2 to ensure the structural strength of the support frame 2 while reducing the structural weight of the support frame 2. The top inner side of the support frame 2 is fixedly sleeved with the bottom structure of the mixing tank 1, and a reinforcing ring plate is fixedly sleeved on the bottom inner side of the support frame 2 to improve the structural strength of the support frame 2.

[0035] In use, for the output of raw materials inside the mixing tank 1, the valve inside the discharge valve pipe 3 can be opened to provide a flow channel. At the same time as the material is discharged, the servo motor 5 can be started simultaneously, so that the output end of the servo motor 5 drives the first drive shaft 7 and the multiple first stirring rods 14 associated with the first drive shaft 7 to synchronously stir the mixed raw materials inside the mixing tank 1, thereby increasing the flow speed of the mixed raw materials, speeding up the discharge speed and reducing the amount of raw material residue in the later stage.
