Description

Technical Field

[0001] The utility model relates to the technical field of ancient book pages, in particular to a mixing device for adhesives used in ancient book pages. Background Art

[0002] In the process of binding ancient book pages, adhesives are needed for bonding, which are mostly water-soluble adhesives. Synthetic adhesives are composed of a main agent and auxiliary agents. The main agent is also called main material, base material or adhesive; auxiliary agents include curing agents, diluents, plasticizers, fillers, coupling agents, initiators, thickeners, antioxidants, polymerization inhibitors, stabilizers, complexing agents, emulsifiers, etc. According to requirements and uses, flame retardants, foaming agents, defoaming agents, colorants and mildewproofing agents can also be included. The characteristics are fluidity, wettability, strong viscosity, non-toxicity, a certain coating time limit and solidification time, stable performance, and a certain degree of flexibility. However, the existing adhesives need to be prepared in advance before applying them to ancient book pages. Mixing, however, most of the existing mixing devices for adhesives for ancient books and albums adopt the method of placing the mixing device in a position in contact with the air after the mixing equipment is completed, and waiting for a certain period of time to be fully applied. If the time is too long, the fluidity of the adhesive will be reduced, and the adhesive will easily solidify, so that it will be difficult to discharge the adhesive from the mixing device at the end, and it will be difficult to clean the adhesion and stirring device. For this reason, a mixing device for adhesives for ancient books and albums is designed, which is convenient for sealed storage, reduces the solidification speed of the adhesive, and is convenient for cleaning the interior as the discharge proceeds. At the end, it is also convenient to blow out the residual adhesive, thereby ensuring the cleanliness of the interior of the vertical mixing tank, and does not require additional cleaning operations.

[0015] The device for mixing adhesive for ancient books and albums can rotate a stirring shaft to drive a mixing and stirring mechanism to rotate, thereby mixing and stirring adhesive raw materials in a vertical mixing tank. During stirring, the lifting mechanism can drive a sealing cover to seal the connection between the feeding mechanism and the vertical mixing tank, thereby reducing the solidification rate of the adhesive. After stirring is completed, the sealing cover can continue to descend as the material is discharged through the discharge mechanism. While descending, the adhesive on the side wall of the vertical mixing tank is pushed downward. When the material is discharged to the position where the sealing cover descends to the top of the mixing and stirring mechanism, the mixing and stirring mechanism scrapes off the adhesive adhering to the bottom of the sealing cover. Then, the blowing structure provided on the sealing cover can blow the adhesive remaining at the bottom of the vertical mixing tank out of the discharge mechanism. The device for mixing adhesive for ancient books and albums is convenient for sealed storage, reduces the solidification rate of the adhesive, and is convenient for cleaning the interior as the material is discharged. At the end, the residual adhesive can also be blown out conveniently, thereby ensuring the cleanliness of the interior of the vertical mixing tank without the need for additional cleaning operations.

Furthermore, a mixing motor 5 for driving the stirring shaft 2 to rotate is fixedly installed on the top of the vertical mixing tank 1. Furthermore, the feeding mechanism includes a feeding pipe 6 fixedly connected to the top side of the vertical mixing tank 1, and a feeding hopper 7 is provided on the top of the feeding pipe 6. The discharge mechanism includes a discharge valve 4 fixedly connected to the bottom of the vertical mixing tank 1. Furthermore, the bottom of the vertical mixing tank 1 is set to an arc shape, and the mixing and stirring mechanism 3 is in line and surface contact with the inner bottom of the vertical mixing tank 1, which is convenient for scraping off the adhesive on the inner bottom of the vertical mixing tank 1, and a plurality of legs are fixedly connected to the bottom of the vertical mixing tank 1. Further, the mixing and stirring mechanism 3 can be set to a spiral stirring blade.

[0026] Specifically, the mixing and stirring mechanism 3 is configured as a horizontal structure whose top can be in line-surface contact with the bottom of the sealing cover 8, so that when the sealing cover 8 descends to the bottom and contacts the top of the mixing and stirring mechanism 3, the mixing and stirring mechanism 3 is driven to rotate by the stirring shaft 2, and the adhesive adhering to the bottom of the sealing cover 8 can be scraped off.

[0027] Specifically, the blowing structure includes a fixed cover 10 fixedly connected to the sealing cover 8, and the bottom of the fixed cover 10 is slidably matched with a sealing slider 11 with a flat bottom.
