Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production, in particular to a raw material mixing device for non-woven fabric production. Background Art

[0002] Nonwoven fabric, also known as nonwoven fabric or nonwovens, is a fabric that does not require spinning and weaving. It is made by aligning or randomly arranging textile short fibers or filaments to form a fiber web structure, and then strengthening it by mechanical, thermal bonding or chemical methods. In the production process of nonwoven fabrics, multiple raw materials such as polymer particles, additives, masterbatches, etc. need to be mixed to obtain a uniform raw material mixture.

[0003] The raw material mixing device for non-woven fabric production in the prior art has a relatively simple mixing structure, and the mixing is uneven. During the mixing process, the raw materials will settle and accumulate at the bottom of the mixing barrel under the action of gravity, and the raw materials cannot be fully stirred, which affects the mixing effect and mixing quality. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a raw material mixing device for non-woven fabric production.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions: a raw material mixing device for non-woven fabric production, comprising a stirring barrel with an opening at the top, a barrel cover is arranged on the top of the stirring barrel, a feed pipe is fixed and connected to the upper surface of the barrel cover, a discharge pipe is fixed and connected to the side wall of the stirring barrel, a valve is arranged on the discharge pipe, a mounting barrel is fixed to the bottom of the stirring barrel, a stirring assembly for mixing raw materials is jointly installed on the mounting barrel and the stirring barrel, the stirring assembly comprises a main rotating shaft which is arranged through the bottom of the stirring barrel and is rotatably connected, a plurality of main stirring rods which are fixedly sleeved on the main rotating shaft, a plurality of secondary rotating shafts which are arranged through the bottom of the stirring barrel and are rotatably connected, and a plurality of secondary stirring rods which are fixedly sleeved on the secondary rotating shaft, the plurality of secondary rotating shafts are evenly distributed about the axis of the main rotating shaft, the plurality of secondary stirring rods are staggered with the plurality of main stirring rods, and a driving assembly for driving the main rotating shaft and the plurality of secondary rotating shafts to rotate simultaneously is installed in the mounting barrel.

[0006] By adopting the above technical scheme, when the non-woven fabric raw materials need to be mixed, the staff puts a variety of raw materials into the mixing barrel through the feed port, and then drives the main rotating shaft and multiple auxiliary rotating shafts to rotate simultaneously through the driving assembly. Since the main rotating shaft and the auxiliary rotating shaft are arranged at the bottom of the mixing barrel, the multiple auxiliary stirring rods and the multiple main stirring rods are staggered, so that the raw materials in the mixing barrel and the raw materials at the bottom are fully and evenly stirred, thereby improving the mixing effect and mixing quality of the non-woven fabric raw materials.

[0007] Furthermore, the driving assembly includes a driving gear fixedly mounted on the main shaft, a driven gear fixedly mounted on the auxiliary shaft and meshing with the driving gear, and a driving motor fixed to the bottom wall of the mounting tube, and the output shaft end of the driving motor is fixed to the lower end of the main shaft.

[0008] By adopting the above technical solution, when stirring is required, the staff starts the first motor to drive the main shaft to rotate, thereby causing multiple main stirring rods to rotate. Since the driving gear is meshed with the driven gear, and the driven gear is fixedly sleeved on the secondary shaft, the secondary shaft and the secondary stirring rod rotate simultaneously with the main shaft. Under the cooperation of the main stirring rod and the secondary stirring rod, the raw materials in the mixing barrel are mixed, reducing the probability of insufficient and uneven mixing of the raw materials.

[0009] Furthermore, one side of the installation tube is open, and a baffle for closing the opening of the installation tube is hingedly connected to the side wall of the installation tube.

[0010] By adopting the above technical solution, the staff can install or disassemble the drive assembly by opening the baffle, which is convenient for maintenance and repair of the drive assembly in the installation cylinder.

[0011] Furthermore, a lifting assembly for lifting the barrel cover is installed on the mixing barrel, and the lifting assembly includes a mounting plate fixed to the side wall of the mixing barrel, a cylinder fixed to the upper surface of the mounting plate, and a fixing plate fixed to the piston rod end of the cylinder and to the side wall of the barrel cover.

[0012] By adopting the above technical solution, when mixing is completed, the staff can control the cylinder to lift the barrel cover upwards, thereby cleaning the residual raw materials in the mixing barrel, reducing the probability of raw materials adhering to the inner wall of the mixing barrel.

[0013] Furthermore, an annular rubber sheet is fixed to the bottom of the barrel cover.

[0014] By adopting the above technical solution, the annular rubber sheet is made of rubber material with good sealing properties. The barrel cover cooperates with the mixing barrel and presses against the annular rubber sheet, thereby enhancing the sealing performance of the barrel cover on the mixing barrel and reducing the probability of raw materials leaking from the mixing barrel.

[0015] Furthermore, the side wall of the mixing barrel is provided with a protective shell for covering the cylinder.

[0016] By adopting the above technical solution, the protective shell protects the cylinder and reduces the probability of the cylinder being damaged under the action of external force.

[0017] Furthermore, the inner bottom wall of the mixing barrel is arranged to be inclined downward toward the discharge pipe.

[0018] By adopting the above technical solution, the inclined bottom wall of the mixing barrel allows the raw materials to flow toward the side of the discharge pipe under the action of gravity, reducing the probability of residual raw materials on the bottom wall of the mixing barrel, which is conducive to the discharge of the mixed raw materials from the discharge pipe.

[0019] Furthermore, a plurality of supporting legs are fixed to the bottom of the mixing barrel, and a rubber block is fixed to the lower end of each supporting leg.

[0020] By adopting the above technical solution, the rubber block is made of rubber material, the surface of which has a large friction coefficient and the material is elastic, which increases the friction force at the lower end of the supporting leg, reduces the probability of displacement of the supporting leg and the mixing barrel, and reduces the vibration generated during the mixing process.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In the present application, when the non-woven fabric raw materials need to be mixed, the staff puts a variety of raw materials into the mixing barrel through the feed port, and then drives the main rotating shaft and multiple auxiliary rotating shafts to rotate simultaneously through the driving assembly. Since the main rotating shaft and the auxiliary rotating shaft are arranged at the bottom of the mixing barrel, the multiple auxiliary stirring rods and the multiple main stirring rods are staggered, so that the raw materials in the mixing barrel and the raw materials at the bottom are fully and evenly stirred, thereby improving the mixing effect and mixing quality of the non-woven fabric raw materials;

[0023] 2. In the present application, when stirring is required, the staff starts the first motor to drive the main shaft to rotate, thereby causing multiple main stirring rods to rotate. Since the driving gear is meshed with the driven gear, and the driven gear is fixedly sleeved on the secondary shaft, the secondary shaft and the secondary stirring rod rotate simultaneously with the main shaft. Under the cooperation of the main stirring rod and the secondary stirring rod, the raw materials in the mixing barrel are mixed, reducing the probability of insufficient and uneven mixing of the raw materials;

[0024] 3. In the present application, when the mixing is completed, the staff can control the cylinder to raise the barrel cover, thereby cleaning the residual raw materials in the mixing barrel, reducing the probability of raw materials adhering to the inner wall of the mixing barrel.

[0029] like Figure 1 and Figure 2 As shown, an embodiment of the present application discloses a raw material mixing device for non-woven fabric production, including a stirring barrel 1, a barrel cover 2, a feed pipe 3, a discharge pipe 4, a mounting cylinder 5, a stirring assembly 6 and a driving assembly 7.

[0030] The mixing barrel 1 is a cylindrical structure with an opening at the top. The barrel cover 2 is a disc-shaped structure, and the barrel cover 2 is arranged on the top of the mixing barrel 1. The feed pipe 3 is a vertically arranged circular tubular structure, and the feed pipe 3 is fixed and connected to the upper surface of the barrel cover 2.

[0031] The stirring assembly 6 is installed on the mounting cylinder 5 and the stirring barrel 1, and is used to mix the raw materials. The stirring assembly 6 includes a main rotating shaft 61, a main stirring rod 62, a secondary rotating shaft 63 and a secondary stirring rod 64. The main rotating shaft 61 is a vertically arranged round rod-shaped structure. The main rotating shaft 61 is arranged through the bottom of the stirring barrel 1 and is rotatably connected, and the axis of the main rotating shaft 61 coincides with the axis of the stirring barrel 1. The main stirring rod 62 is a horizontally arranged round rod-shaped structure. The main stirring rod 62 is fixedly sleeved on the main rotating shaft 61, and a plurality of main stirring rods 62 are provided. The secondary rotating shaft 63 is a vertically arranged round rod-shaped structure. The secondary rotating shaft 63 is arranged through the bottom of the stirring barrel 1 and is rotatably connected. A plurality of secondary rotating shafts 63 are provided, and the plurality of secondary rotating shafts 63 are evenly distributed about the axis of the main rotating shaft 61. The auxiliary stirring rod 64 is a horizontally arranged round rod-shaped structure. The auxiliary stirring rod 64 is fixedly sleeved on the auxiliary rotating shaft 63 . There are multiple auxiliary stirring rods 64 , and the multiple auxiliary stirring rods 64 are staggered with the multiple main stirring rods 62 .

[0032] The driving assembly 7 is installed in the installation tube 5, and is used to drive the main rotating shaft 61 and multiple secondary rotating shafts 63 to rotate simultaneously. The driving assembly 7 includes a driving gear 71, a driven gear 72 and a driving motor 73. The driving gear 71 is fixedly sleeved on the main rotating shaft 61, and the axis of the driving gear 71 coincides with the axis of the main rotating shaft 61. There are multiple driven gears 72, and the multiple driven gears 72 are respectively fixedly sleeved on the multiple secondary rotating shafts 63. The multiple driven gears 72 are all meshed with the driving gear 71, and the axes of the driven gears 72 coincide with the axes of the secondary rotating shafts 63. The driving motor 73 is fixed to the inner bottom wall of the installation tube 5, and the output shaft end of the driving motor 73 is fixed to the lower end of the main rotating shaft 61, and the output shaft axis of the driving motor 73 coincides with the axis of the main rotating shaft 61.

[0033] When the non-woven fabric raw materials need to be mixed, the staff puts a variety of raw materials into the mixing barrel 1 through the feed port, and then drives the main shaft 61 to rotate through the first motor, so that the multiple main stirring rods 62 rotate. Since the driving gear 71 is meshed with the driven gear 72, and the driven gear 72 is fixedly sleeved on the secondary shaft 63, the secondary shaft 63 and the secondary stirring rod 64 rotate simultaneously with the main shaft 61. Since the main shaft 61 and the secondary shaft 63 are arranged at the bottom of the mixing barrel 1, the multiple secondary stirring rods 64 are staggered with the multiple main stirring rods 62, so that the raw materials in the mixing barrel 1 and the raw materials at the bottom are fully and evenly stirred, thereby improving the mixing effect and mixing quality of the non-woven fabric raw materials.

[0034] In order to facilitate the maintenance and inspection of the drive assembly 7, one side of the installation cylinder 5 is opened, and the side wall of the installation cylinder 5 is hinged with a baffle 8 for closing the opening of the installation cylinder 5. The staff can open the baffle 8 to install or disassemble the drive assembly 7, thereby facilitating the maintenance and inspection of the drive assembly 7 in the installation cylinder 5.

[0035] In order to clean the residual raw materials in the mixing barrel 1, a lifting assembly 9 is installed on the mixing barrel 1 for lifting the barrel cover 2, and the lifting assembly 9 includes a mounting plate 91, a cylinder 92 and a fixing plate 93. The mounting plate 91 is a rectangular rod-shaped structure, and the mounting plate 91 is fixed to the side wall of the mixing barrel 1.

The fixing plate 93 is a rectangular plate-shaped structure, and the fixing plate 93 is fixed to the end of the piston rod of the cylinder 92, and the side wall of the fixing plate 93 is fixed to the side wall of the barrel cover 2. When the mixing is completed, the staff can control the cylinder 92 to lift the barrel cover 2 upward, thereby cleaning the residual raw materials in the mixing barrel 1, reducing the probability of the raw materials adhering to the inner wall of the mixing barrel 1.

[0036] In order to reduce the probability of raw materials leaking out of the mixing barrel 1, an annular rubber sheet 10 is fixed to the bottom of the barrel cover 2. The annular rubber sheet 10 is made of rubber material, and its material has good sealing performance. The barrel cover 2 cooperates with the mixing barrel 1 and presses against the annular rubber sheet 10, thereby enhancing the sealing performance of the barrel cover 2 to the mixing barrel 1, thereby reducing the probability of raw materials leaking out of the mixing barrel 1.

[0037] In order to protect the cylinder 92, a protective shell 11 for covering the cylinder 92 is provided on the side wall of the mixing barrel 1. The protective shell 11 protects the cylinder 92 and reduces the probability of damage to the cylinder 92 under the action of external force.

[0038] In order to reduce the probability of residual raw materials on the inner bottom wall of the mixing barrel 1, the inner bottom wall of the mixing barrel 1 is inclined downward toward the side of the discharge pipe 4. The inclined inner bottom wall of the mixing barrel 1 allows the raw materials to flow toward the side of the discharge pipe 4 under the action of gravity, thereby reducing the probability of residual raw materials on the inner bottom wall of the mixing barrel 1, which is conducive to the discharge of the mixed raw materials from the discharge pipe 4.

[0039] In this embodiment, a plurality of supporting legs 12 are fixed to the bottom of the mixing barrel 1, and a rubber block 13 is fixed to the lower end of each supporting leg 12. The rubber block 13 is made of rubber material, and its surface has a large friction coefficient and the material is elastic, which increases the friction force at the lower end of the supporting leg 12, reduces the probability of displacement of the supporting leg 12 and the mixing barrel 1, and reduces the vibration generated during the mixing process.

[0040] The use principle of a raw material mixing device for non-woven fabric production in this embodiment is as follows: when the non-woven fabric raw materials need to be mixed, the staff puts a variety of raw materials into the mixing barrel 1 through the feed port, and then drives the main shaft 61 to rotate through the first motor, thereby rotating the multiple main stirring rods 62. Since the driving gear 71 is meshed with the driven gear 72, and the driven gear 72 is fixedly sleeved on the secondary shaft 63, the secondary shaft 63 and the secondary stirring rod 64 rotate simultaneously with the main shaft 61. Since the main shaft 61 and the secondary shaft 63 are arranged at the bottom of the mixing barrel 1, the multiple secondary stirring rods 64 are staggered with the multiple main stirring rods 62, so that the raw materials in the mixing barrel 1 and the raw materials at the bottom are fully and evenly stirred, thereby improving the mixing effect and mixing quality of the non-woven fabric raw materials.
