Description

Technical Field

[0001] The utility model relates to the technical field of mixer auxiliary equipment, in particular to a mixing frame device with a bottom scraping function. Background Art

[0002] Planetary mixer is a new type of mixing equipment, suitable for mixing various high-viscosity and high-solid materials. After the planetary mixer completes the mixing of materials, there will usually be residual materials attached to its inner wall surface. In the actual production process, the residual materials need to be removed in time to avoid affecting the subsequent production process.

[0003] In the prior art, a scraper device is usually added to the planetary mixer to scrape off the residual material inside. The scraper device has the following structure: it includes a connecting arm, one end of which is connected to the output end of the transmission mechanism of the planetary mixer, and the other end is connected to the scraper through a threaded fastener. The transmission mechanism drives the scraper to rotate through the connecting arm, so that the residual material inside the container is scraped off by the scraper. This scraper device usually has the following disadvantages:

[0004] (1) The additional scraper and connecting arm occupy a large space, resulting in a reduction in the working space of the original stirring device and dispersing device in the planetary mixer, thereby reducing its stirring efficiency;

[0005] (2) The scraper and the connecting arm are fastened with threaded fasteners, and multiple slots for installing the fasteners need to be opened on the scraper and the connecting arm. During the actual working process, the residual material will adhere to and penetrate into the slots, thereby increasing the cleaning dead zone on the scraper device, which is not suitable for use in sanitary food-grade related equipment. Utility Model Content

[0006] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a stirring frame device with a bottom scraping function. Through the stirring frame mechanism and the scraper mechanism, the residual material attached to the bottom of the container can be effectively scraped off, thereby reducing the accumulated material; no fasteners are required between the stirring frame mechanism and the scraper mechanism, reducing the cleaning dead zone and facilitating cleaning, so that it is suitable for sanitary food-grade equipment.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A stirring frame device with bottom scraping function, comprising:

[0009] A mixing frame mechanism, the bottom of which is provided with a dovetail groove;

[0010] The scraper mechanism is installed in the dovetail groove, and its outer wall surface is closely fitted with the inner wall surface of the dovetail groove;

[0011] The bottom end surface of the scraper mechanism is lower than the bottom end surface of the stirring frame mechanism, so that the bottom end surface of the scraper mechanism fits the inner bottom wall surface of the container. When the stirring frame mechanism rotates, the scraper mechanism is driven to rotate, thereby scraping off the residual material on the inner bottom wall surface of the container through the scraper mechanism.

[0012] As a further improvement of the above technical solution:

[0013] The structure of the stirring frame mechanism is as follows: it includes a connecting sleeve, and propeller blades are symmetrically arranged on the outer circumferential surface of the connecting sleeve. The bottoms of the two propeller blades are connected by a cross piece, and dovetail grooves are simultaneously provided on the bottom end surfaces of the two propeller blades and the bottom end surfaces of the cross piece.

[0014] A connecting hole is provided in the middle of the connecting sleeve, and the connecting hole is used to connect with the output shaft of the transmission mechanism.

[0015] The cross section of the dovetail groove is in an inverted trapezoidal shape.

[0016] The structure of the scraper mechanism is as follows: it includes a scraper body for scraping off residual materials, and symmetrically arranged inclined surfaces are provided on the opposite side walls of the scraper body, so that the outer wall surface of the scraper body corresponds to the inner wall surface of the dovetail groove.

[0017] The side wall of the scraper body below the single inclined surface is arranged perpendicularly to the bottom end surface of the scraper body, so that a right-angle edge is formed at the connection between the side wall of the scraper body and the bottom end surface of the scraper body, and the scraper body scrapes off the residual material through the right-angle edge.

[0018] The scraper body is made of non-metallic material.

[0019] The scraper mechanism and the stirring frame mechanism are assembled in an interference fit manner.

[0020] The beneficial effects of the utility model are as follows:

[0021] The utility model discloses the planetary mixer has a compact and reasonable structure and is easy to operate. By integrating the scraper mechanism into the mixing frame mechanism, a compact layout can be achieved, thereby avoiding the scraper mechanism from affecting the flow field of materials inside the planetary mixer and improving the mixing efficiency of the planetary mixer. At the same time, the mixing frame device has no cleaning dead zone and can be suitable for sanitary food-grade equipment.

[0022] The utility model also has the following advantages:

[0023] (1) In the utility model, a dovetail groove is provided at the bottom of the mixing frame mechanism, and the scraper body can be installed by inserting the dovetail groove, which is convenient for disassembly and replacement of the scraper, and is convenient for subsequent disassembly and cleaning, without the need to use fasteners to reduce cleaning dead zones.

[0024] (2) In the present invention, a slope is provided on the scraper body corresponding to the shape of the dovetail groove, and an assembly form based on interference fit can effectively prevent materials from entering between the dovetail groove and the scraper body.

[0025] (3) In the utility model, by providing right-angle edges on the scraper body, residual materials in the container can be effectively scraped off. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The specific implementation of the utility model is described below in conjunction with the accompanying drawings.

[0037] The structure and functions of the utility model are as follows:

[0038] like Figure 1-Figure 7As shown, a mixing frame device with a bottom scraping function comprises: a mixing frame mechanism 1, a dovetail groove 104 is provided at the bottom of the mixing frame mechanism; a scraper mechanism 2 is installed in the dovetail groove 104, and its outer wall surface is tightly fitted with the inner wall surface of the dovetail groove 104; the bottom end surface of the scraper mechanism 2 is lower than the bottom end surface of the mixing frame mechanism 1, so that the bottom end surface of the scraper mechanism 2 is fitted with the inner bottom wall surface of the container 3, and when the mixing frame mechanism 1 rotates, the scraper mechanism 2 is driven to rotate, so that the scraper mechanism 2 is used to scrape off the residual material on the inner bottom wall surface of the container 3. The mixing frame device of the utility model comprises a mixing frame mechanism 1 and a scraper mechanism 2, and the scraper mechanism 2 is integrated on the mixing frame mechanism 1, so that when the mixing frame mechanism 1 rotates, it can drive the scraper mechanism 2 to rotate, so as to scrape off the residual material on the bottom wall surface of the container 3. Among them,

[0039] like Figure 1-Figure 4 As shown, the structure of the stirring frame mechanism 1 is: including a connecting sleeve 101, on the outer circumferential surface of which propeller blades 102 are symmetrically arranged, the bottoms of the two propeller blades 102 are connected by a cross piece 103, and dovetail grooves 104 are simultaneously provided on the bottom end surfaces of the two propeller blades 102 and the bottom end surfaces of the cross piece 103.

[0040] A connecting hole is provided in the middle of the connecting sleeve 101, and the connecting hole is used to connect with the output shaft of the transmission mechanism 4. The stirring frame mechanism 1 is connected with the output shaft of the transmission mechanism 4 through the connecting hole.

[0041] like Figure 1 , Figure 5-Figure 6 As shown, the structure of the scraper mechanism 2 is: it includes a scraper body 201 for scraping off residual materials, and symmetrically arranged inclined surfaces 202 are provided on the opposite side walls of the scraper body 201, so that the outer wall surface of the scraper body 201 corresponds to the inner wall surface shape of the dovetail groove 104.

[0042] The side wall surface of the scraper body 201 below the single inclined surface 202 is arranged perpendicularly to the bottom end surface of the scraper body 201, so that a right-angle edge 203 is formed at the connection between the side wall surface of the scraper body 201 and the bottom end surface of the scraper body 201, and the scraper body 201 scrapes off the residual material through the right-angle edge 203. The right-angle edge 203 can scrape up the residual material attached to the inner bottom wall surface of the container 3, and by rotating the scraper body 201, the scraped residual material is gathered, which is convenient for subsequent cleaning work.

[0043] The cross section of the dovetail groove 104 is inverted trapezoidal. The dovetail groove 104 is used to install the scraper body 201.

[0044] An interference fit assembly method is adopted between the scraper mechanism 2 and the mixing frame mechanism 1, that is, an interference fit assembly method is adopted between the scraper body 201 and the dovetail groove 104. Specifically, the top wall surface of the scraper body 201 is fitted with the inner top wall surface of the dovetail groove 104, and at the same time, the two inclined surfaces 202 on the scraper body 201 are fitted with the inner wall surface of the dovetail groove 104, so that the scraper body 201 is inserted into the dovetail groove 104, and the right-angle edge 203 arranged on the scraper body 201 is lower than the bottom end surface of the cross piece 103.

[0045] The scraper body 201 is made of non-metallic material. The non-metallic material is softer, so it can better fit the inner wall surface of the dovetail groove 104 , thereby preventing the material in the container 3 from entering between the dovetail groove 104 and the scraper body 201 .

[0046] The working process of the utility model is as follows:

[0047] like Figure 7 As shown, the mixing frame device of the utility model is used in a planetary mixer, and the structure of the planetary mixer includes a container 3 for holding materials and a transmission mechanism 4 for transmitting power;

[0048] The input end of the transmission mechanism 4 is connected to the output end of the driving device, and the output end of the transmission mechanism 4 is an output shaft, which is connected to the stirring frame mechanism 1;

[0049] The driving device drives the mixing frame mechanism 1 to rotate through the transmission mechanism 4, thereby driving the scraper mechanism 2 to rotate;

[0050] When the scraper mechanism 2 rotates, its bottom wall surface contacts the inner bottom wall surface of the container 3 , and scrapes up the residual material in the container 3 through the right-angle edge 203 .

[0051] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
