Description

Technical Field

[0001] The utility model belongs to the technical field of glue mixing, and in particular relates to an automatic glue mixing device. Background Art

[0002] Currently, to prepare glue, it is necessary to manually sample at least two types of glue separately, then pour them into a stainless steel barrel after manual weighing, and then use a blender to mix and prepare them. After the preparation is completed, the glue is transferred to a coating tank for use. In the process of introducing the glue into the coating tank after preparation, the mixed glue mostly relies on its own weight to flow out from the bottom discharge port of the mixing barrel. At this time, some mixed glue will remain on the inner wall of the stainless steel mixing barrel, resulting in an inaccurate amount of mixed glue in the coating tank, affecting the subsequent mixing of the coating liquid.

[0003] Therefore, an automatic glue mixing device is designed to solve the technical problem in the prior art that when the mixed glue flows out of the mixing barrel by its own weight, some mixed glue will remain on the inner wall of the mixing barrel, resulting in inaccurate amount of mixed glue and thus affecting the subsequent coating effect.

[0004] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0046] Research has found that the current preparation of glue requires manual sampling of at least two glues, which are then poured into stainless steel barrels after manual weighing, and then stirred and prepared with a blender. After the preparation is completed, it is transferred to the coating tank for use. In the process of the glue being prepared and introduced into the coating tank, the mixed glue mostly relies on its own weight to flow out from the bottom discharge port of the mixing barrel. At this time, some mixed glue will remain on the inner wall of the stainless steel mixing barrel, resulting in inaccurate amount of mixed glue in the coating tank, affecting the subsequent mixing of the coating liquid.

[0047] Based on the above research, an embodiment of the present disclosure provides an automatic glue mixing device, which is equipped with a scraping mechanism inside a mixing tank. When the multiple glues in the mixing tank are mixed, the scraping mechanism is started during the process of the mixed glue flowing out from the discharge port at the bottom of the mixing tank to scrape off the mixed glue adhered to the inner wall of the mixing tank, so that the mixed glue adhered to the inner wall of the mixing tank flows to the bottom of the mixing tank and flows out, thereby ensuring the accuracy of the amount of mixed glue used for subsequent coating.

[0048] The defects in the above solutions are the results obtained by the utility model inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article should be the contributions made by the utility model inventor to the present invention during the disclosure process.

[0049] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0050] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0051] In some embodiments, as Figure 1As shown, each glue tank 1 is connected to the mixing tank 2 through a feed pipe 11, and the mixing tank 2 is placed on the upper end surface of a weighing piece 3. Preferably, the weighing piece 3 is preferably an electronic platform scale, and the digital display of the weighing piece 3 is reset to zero. At this time, according to the weight requirements of each type of glue, the feed pneumatic diaphragm pump 10 at the top of the corresponding glue tank 1 is started respectively, and the corresponding glue is pumped into the mixing tank 2 along the F1 direction, and the digital display of the weighing piece 3 is read in real time. When the weight is reached, the current feed pneumatic diaphragm pump 10 is stopped, and another type of glue is replaced and pumped until all required types of glue and the weight of various types of glue are pumped.

[0052] In some embodiments, as Figure 1 As shown, after various types of glue are pumped into the mixing tank 2, the first stirring motor 20 is started, and its output end drives the stirring shaft 21 to rotate, and then drives a number of stirring paddles fixed on the outer wall of the stirring shaft 21 to rotate, so as to mix the various types of glue. After the mixing is completed, the control valve is opened. At this time, the mixed glue flows through the mixed glue circulation pipe 24 in the direction of F2 under the action of gravity and enters the liquid storage tank 4 for storage.

[0053] In some embodiments, as Figure 1 As shown, the second stirring motor 40 is fixed on the upper end surface of the liquid storage tank 4, and the connecting component of the output end of the second stirring motor 40 is consistent with that of the first stirring motor 40, that is, the output end of the second stirring motor 40 is also connected to a stirring shaft and a stirring paddle, so as to continuously stir the mixed glue inside the liquid storage tank 4 after the second stirring motor 40 is started, so as to avoid stratification of the mixed glue after standing; when the glue in the coating tank 5 is used up or the amount of glue is small, the transmission pneumatic diaphragm pump 41 is started, and the mixed glue in the liquid storage tank 4 is pumped into the coating tank 5 for use through the mixing feed pipe 42.

[0054] In some embodiments, as Figure 2 As shown, when the first stirring motor 20 is started in the forward direction and the glue in the mixing tank 2 is mixed, the control valve is opened and the mixed glue flows out through the mixed glue circulation pipe 24. At this time, the first stirring motor 20 is started in the reverse direction, and its output end drives the stirring shaft 21 to rotate in the reverse direction, so as to drive the one-way bearing sleeve 22 to rotate, and then drives the driven rod 220 fixed on the outer wall of the one-way bearing sleeve 22 and the scraper 221 vertically fixed on the driven rod 220 to rotate. The end face of the scraper 221 close to the inner wall of the mixing tank 2 is arc-shaped and tangent to the inner wall of the mixing tank 2. During the rotation of the scraper 221, the residual mixed glue on the inner wall of the mixing tank 2 can be scraped, and the residual glue can flow out under the action of gravity.

[0055] To summarize, by arranging a scraping mechanism inside the mixing tank, when the various glues in the mixing tank are mixed, the scraping mechanism is started during the process of the mixed glue flowing out from the discharge port at the bottom of the mixing tank to scrape off the mixed glue adhering to the inner wall of the mixing tank, so that the mixed glue adhering to the inner wall of the mixing tank flows to the bottom of the mixing tank and flows out, thereby ensuring the accuracy of the amount of mixed glue used for subsequent coating.

[0056] In the description of the embodiments of the present invention, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0057] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, terms such as "first", "second" and other numerical terms do not imply an order or sequence when used herein unless expressly indicated above. Therefore, without departing from the teachings of the example embodiments, the first element, component, region, layer or section discussed above may be referred to as a second element, component, region, layer or section.

[0058] Spatially relative terms, such as "inside," "outside," "below," "beneath," "down," "above," "on," etc., may be used herein to describe the relationship of one element or feature to another element or feature as illustrated in the figures. In addition to the orientations depicted in the figures, spatially relative terms may be intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as being "below" or "below" other elements or features will be oriented to be "above" the other elements or features. Thus, the example term "below" may encompass both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0059] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
