Description

Technical Field

[0001] This utility model belongs to the field of mixing equipment technology, and in particular relates to a non-woven fabric raw material mixing equipment. Background Technology

[0002] Nonwoven fabric is a product that resembles cloth but is not cloth without the need for a weaving process. The production process requires mixing equipment to mix the raw materials of nonwoven fabric. The raw materials mainly include polyester fiber, polyester fiber and natural plant fiber, etc. The mixing equipment is used to mix multiple raw materials in proportion and is widely used in the field of nonwoven fabric production, especially in the production of nonwoven fabrics that require high quality and stability.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing nonwoven fabric raw material mixing equipment:

[0004] 1. The hybrid shaft is directly mounted on the housing via bearings, which makes the assembly and disassembly of the hybrid shaft cumbersome and inconvenient to use assembly measures to support the hybrid shaft so that it can be quickly assembled and disassembled.

[0005] 2. The mixing blades are bolted to the mixing shaft. Loosening of the bolts can easily cause the blades to loosen, making it inconvenient to install assembly measures on the mixing shaft to prevent the mixing blades from loosening. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a nonwoven fabric raw material mixing device. This addresses the issues of existing mixing shafts being directly mounted on the housing via bearings, which leads to cumbersome assembly and disassembly processes and makes it inconvenient to use assembly measures to support the mixing shaft. Furthermore, the mixing blades are bolted to the mixing shaft, and loose bolts can easily cause the blades to loosen, making it difficult to add assembly measures to the mixing shaft to prevent the blades from becoming loose.

[0007] The purpose and effectiveness of this utility model's nonwoven fabric raw material mixing equipment are achieved through the following specific technical means:

[0008] A nonwoven fabric raw material mixing device includes a mixing shaft body; both ends of the mixing shaft body are provided with assembly bearing shafts in the left and right directions, a fixed column is provided in the middle of the assembly bearing shaft, a regular hexagonal prism is provided on the outer end face of the fixed column of the assembly bearing shaft, a limit ring plate is provided on the outer circumference of the inner end of the fixed column of the assembly bearing shaft, a semi-cylinder with the plane facing upward is provided at the bottom of the inner end face of the fixed column of the assembly bearing shaft, an insertion blind hole is opened on the top end face of the semi-cylinder of the assembly bearing shaft, and a thread is opened on the outer circumference of the semi-cylinder of the assembly bearing shaft.

[0009] Furthermore, a blade assembly rod is inserted into the assembly hole of the material mixing shaft. The top of the left and right end faces of the blade assembly rod is provided with a plane-downward semi-cylinder, and a pull-out hole that runs through the top and bottom is opened in the center of the semi-cylinder of the blade assembly rod.

[0010] Furthermore, a mixing blade plate is inserted into the rectangular hole of the material mixing shaft, and a through-hole is opened in the center of the mixing blade plate. A cutting edge is provided on the top of the rear end face and the bottom of the front end face of the mixing blade plate.

[0011] Furthermore, an anti-loosening limiting post is installed inside the threaded hole of the material mixing shaft. The outer circumference of the anti-loosening limiting post is threaded, and the top end face of the anti-loosening limiting post is provided with a regular hexagonal groove.

[0012] Furthermore, the material mixing shaft is equipped with assembly locking cylinders on the outer circumference of both the left and right ends. The inner circumference of the assembly locking cylinder is threaded, and the outer circumference of the assembly locking cylinder is provided with a regular hexagonal structure.

[0013] Furthermore, the material mixing shaft has threads on the outer circumference of both the left and right ends, a through-hole in the center of the material mixing shaft, and six rectangular holes arranged horizontally and vertically inside the material mixing shaft.

[0014] Furthermore, a material mixing shaft is placed on the semi-cylinder between the assembly bearing shafts. The top of the left and right end faces of the material mixing shaft are provided with a plane-downward semi-cylinder, and a threaded hole that runs through the middle of the semi-cylinder of the material mixing shaft is provided.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The semi-cylinder of the assembling bearing shaft and the semi-cylinder of the material mixing shaft are assembled to form a complete cylinder. The assembly and locking cylinder can be used to assemble and fix the assembling bearing shaft and the material mixing shaft. This solves the problem that the mixing shaft is directly mounted on the housing through the bearing, which makes the disassembly and assembly process of the mixing shaft more complicated and inconvenient to carry the mixing shaft through assembly measures, so that the mixing shaft can be quickly disassembled and assembled.

[0017] The design facilitates the insertion of the mixing blade plate into the rectangular hole of the material mixing shaft, and uses the blade assembly rod for assembly and anti-detachment. At the same time, the assembly bearing shaft limits the movement of the blade assembly rod to prevent it from coming out of the material mixing shaft. This solves the problem that the mixing blades are bolted to the mixing shaft, and loose bolts can easily cause the blades to loosen. It is also inconvenient to add assembly measures to the mixing shaft to prevent the mixing blades from loosening. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides a nonwoven fabric raw material mixing device, including a mixing shaft body 1; both ends of the mixing shaft body 1 are provided with left-right oriented assembly bearing shafts 2, which facilitate the bearing of a material mixing shaft 3, allowing the material mixing shaft 3 to rotate. A fixed column is provided in the middle of the assembly bearing shaft 2, which facilitates the assembly bearing shaft 2 to rotate on the housing via bearings. The outer end face of the fixed column of the assembly bearing shaft 2 is provided with a regular hexagonal prism, which facilitates synchronous rotation with an external power device. A limit ring plate is provided on the outer circumference of the inner end of the fixed column of the assembly bearing shaft 2, which facilitates the limiting of the bearings and the assembly locking cylinder 4. A semi-cylinder with its plane facing upward is provided at the bottom of the inner end face of the fixed column of the assembly bearing shaft 2, which facilitates the mutual fitting with the semi-cylinder of the material mixing shaft 3. An insertion blind hole is provided on the top end face of the semi-cylinder of the assembly bearing shaft 2, which facilitates the prevention of loosening. The positioning post 5 is inserted inside. The outer circumference of the semi-cylinder of the assembly bearing shaft 2 is threaded to facilitate the threaded engagement of the locking cylinder 4. The material mixing shaft 3 is placed on the semi-cylinder between the assembly bearing shafts 2 to facilitate quick assembly and disassembly of the material mixing shaft 3. The top of the left and right end faces of the material mixing shaft 3 are provided with a flat-down semi-cylinder to facilitate mutual engagement with the semi-cylinder of the assembly bearing shaft 2. The semi-cylinder of the material mixing shaft 3 has a threaded hole that runs vertically through the middle to facilitate the installation of the anti-loosening limiting post 5 by thread. The outer circumference of both ends of the material mixing shaft 3 is threaded to facilitate the installation of the locking cylinder 4 by thread. The center of the material mixing shaft 3 has a horizontally through assembly hole to facilitate the insertion of the blade assembly rod 7 inside. The inside of the material mixing shaft 3 has six rectangular holes arranged horizontally and vertically through the middle to facilitate the insertion of the mixing blade plate 6 inside.

[0028] The material mixing shaft 3 has assembly locking cylinders 4 installed on the outer circumference of both ends. These cylinders facilitate fixing the assembly positions of the bearing shaft 2 and the material mixing shaft 3. The inner circumference of the assembly locking cylinder 4 is threaded for easy threaded installation. The outer circumference of the assembly locking cylinder 4 has a regular hexagonal structure for easy rotation with tools. Anti-loosening limiting posts 5 are installed inside the threaded holes of the material mixing shaft 3 to limit and prevent loosening of the assembly locking cylinder 4. The outer circumference of the anti-loosening limiting posts 5 is threaded for easy threaded installation. The top end face of the anti-loosening limiting posts 5 has a regular hexagonal groove for easy disassembly and assembly with tools. A mixing blade plate 6 is inserted into the rectangular hole of the material mixing shaft 3 to facilitate mixing. The blade plate 6 is assembled without bolts. The center of the mixing blade plate 6 has a through-hole for easy passage of the blade assembly rod 7. The top of the rear end face and the bottom of the front end face of the mixing blade plate 6 are provided with cutting edges to facilitate cutting and mixing of non-woven raw materials. The blade assembly rod 7 is inserted into the assembly hole of the material mixing shaft 3 to prevent the mixing blade plate 6 from falling off. The top of the left and right end faces of the blade assembly rod 7 are provided with a flat-down semi-cylinder to facilitate engagement with the semi-cylinder of the assembly bearing shaft 2, so as to prevent the blade assembly rod 7 from rotating and moving left and right. The center of the semi-cylinder of the blade assembly rod 7 has a pull-out hole for easy insertion of tools to pull the blade assembly rod 7 out of the material mixing shaft 3, thereby disassembling the mixing blade plate 6.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In this utility model, such as Figure 1 As shown, the assembly bearing shaft 2 is mounted on the housing via bearings. The housing is in a cut-off state. During use, the hexagonal prism of the assembly bearing shaft 2 needs to be connected to an external power unit. This external power unit drives the assembly bearing shaft 2 to rotate synchronously, which in turn drives the material mixing shaft 3 to rotate synchronously. The material mixing shaft 3 then drives the mixing blade plate 6 to rotate synchronously, thereby achieving the mixing of the nonwoven fabric raw materials. Figure 1 As shown, when disassembling the material mixing shaft 3, the anti-loosening limiting post 5 is engaged with the threaded part of the material mixing shaft 3 by rotating the tool. This causes the anti-loosening limiting post 5 to rise and disengage from the threaded hole of the material mixing shaft 3, thereby releasing the anti-loosening limiting post 5 from its limiting and anti-loosening position on the assembly locking cylinder 4. Then, the assembly locking cylinder 4 is engaged with the threaded part of the assembly bearing shaft 2 and the material mixing shaft 3 by rotating the tool. This causes the assembly locking cylinder 4 to move inward and disengage from the assembly position of the assembly bearing shaft 2 and the material mixing shaft 3, as shown in the diagram. Figure 5As shown, the material mixing shaft 3 is then lifted and detached from the semi-cylinder of the assembly bearing shaft 2, thereby disassembling the material mixing shaft 3. This assembly method solves the problem that the mixing shaft is directly mounted on the housing via bearings, resulting in a cumbersome disassembly and assembly process. When disassembling the mixing blade plate 6, the disassembled material mixing shaft 3 is lifted, and the blade assembly rod 7 is pulled outward by hooking it with a tool through the pull hole, thus removing the blade assembly rod 7 from the inside of the material mixing shaft 3, as shown. Figure 6 As shown, this releases the blade assembly rod 7 from the anti-detachment mechanism of the mixing blade plate 6, and then pulls the mixing blade plate 6 out of the rectangular groove of the material mixing shaft 3, thereby completing the disassembly of the mixing blade plate 6. This assembly method solves the problem that the mixing blade is installed on the mixing shaft by bolts, and the loosening of the bolts can easily lead to the loosening of the blade.

[0031] Example 2: Unlike Example 1, the regular hexagonal structure of the assembly locking cylinder 4 can also be set as a regular heptagonal structure. This makes it necessary to use a special tool that works with the regular heptagonal structure to rotate the assembly locking cylinder 4, thus preventing non-staff members from rotating and disassembling the assembly locking cylinder 4.

[0032] Example 3: The difference from Example 1 is that the regular hexagonal groove of the anti-loosening limiting post 5 can also be set as a regular heptagonal groove, so that the anti-loosening limiting post 5 can only be rotated by a special tool that cooperates with the regular heptagonal groove, thus preventing non-workers from rotating and disassembling the anti-loosening limiting post 5.
