Description

Technical Field

[0001] The utility model relates to the technical field of glue supply devices, in particular to a low-viscosity glue conveying and supplying mechanism. Background Art

[0002] In the prior art, fillers are added to the glue to give the adhesive some special properties to meet the use requirements. The fillers are usually solid particles that do not react chemically with the main material, but can change the properties of the glue. For example, asbestos wool, glass fiber, etc. are added to improve the impact strength; quartz powder, porcelain powder, iron powder, etc. are added to improve the hardness and compression resistance; graphite powder, talcum powder, etc. are added to improve wear resistance; aluminum oxide, titanium dioxide, etc. are added to increase the bonding force. In the glue production process, the glue is first mixed with the ingredients, and the mixed glue is supplied to the dispensing machine for dispensing.

[0003] After searching, the patent publication number CN218358800U discloses "a new type of glue supply and stirring container", including a container body and a stirring device. The interior of the container body is provided with a accommodating space. The stirring device includes two rotating shafts and two corresponding stirring paddles. The two constitute a planetary stirring device for rotating and stirring during glue supply to avoid glue sedimentation, thereby ensuring the consistency of glue at any time and any position, and significantly improving the stirring efficiency of glue; it also includes a plurality of electromagnetic filtering devices, which are arranged at intervals on the inner wall of the container body. When powered on during the glue preparation process, magnetic force can be generated, thereby adsorbing tiny magnetic impurities in the glue in its internal mesh filter element, which can prevent magnetic impurities from scratching and damaging the coating roller in subsequent coating operations, and can prevent magnetic impurities from being mixed in the glue layer and causing adverse effects on the glue layer structure and its application.

[0004] However, most of the existing glue supply devices discharge glue through the lower end of the cylinder, and the glue supply pressure will be affected by the weight of the glue in the cylinder. As the weight of the glue in the cylinder changes, the glue discharge pressure of the cylinder will also change, resulting in changes in the glue discharge amount and unstable glue supply. At the same time, when storing low-viscosity glue containing particulate matter, the particles in this glue are easy to settle in the cylinder, resulting in a high content of particles in the bottom layer of glue inside the cylinder. If the glue is discharged directly through the lower end of the cylinder, it is easy for the particle content in the initial glue supply to be higher, while the particle content in the final glue supply to be lower, resulting in poor glue supply quality. Utility Model Content

[0005] The purpose of the utility model is to provide a low-viscosity glue conveying and supplying mechanism, which not only avoids uneven distribution of particles and improves glue quality, but also avoids the influence of internal glue quantity changes on glue supply pressure, improves the stability of glue supply, and thus improves the overall glue supply quality.

A plurality of first stirring blades are fixedly connected to one end of the stirring rod away from the cover plate, and a plurality of second stirring blades are provided on the circumferential outer wall of the stirring rod and between the first stirring blade and the cover plate.

[0008] The further improved scheme in the above technical scheme is as follows:

[0009] 1. In the above scheme, the first stirring blade and the second stirring blade are both arranged obliquely. When the stirring rod rotates, the first stirring blade and the second stirring blade can push the glue inside the cylinder obliquely upward.

[0010] 2. In the above solution, the length of the first stirring blade is greater than the length of the second stirring blade.

[0011] 3. In the above solution, the second stirring blades located at the same height are arranged at intervals along the circumference of the stirring rod.

[0048] The working principle is:

[0049] When in use, pour the glue liquid into the funnel, and the glue liquid is injected into the cylinder through the glue inlet pipe through the feed valve. When the glue liquid is injected into the cylinder, the gas in the cylinder is discharged through the exhaust valve. Then, start the motor, and the motor output shaft drives the rotating shaft to rotate, so that the rotating shaft can drive the stirring rod to rotate;

[0050] During the rotation of the stirring rod, the inclined first stirring blade and the second stirring blade can push the glue inside the cylinder obliquely upward during the rotation, so that the glue at the bottom layer inside the cylinder can be fully mixed with the glue at the upper layer; after the glue liquid is mixed, the air pressure inside the cylinder is increased through the air inlet valve, so that the glue inside the cylinder flows upward through the glue outlet pipe and the discharge valve in turn, thereby realizing the glue supply work.

[0051] When a low-viscosity glue delivery and supply mechanism is adopted, the stirring rod is driven to rotate through the rotating shaft, so that the first stirring blade and the second stirring blade stir the glue inside the cylinder, which is beneficial to mixing the glue liquid inside the cylinder, avoiding uneven distribution of particles and improving the quality of glue. The air inlet valve can also be opened to increase the internal pressure of the cylinder, so that the glue inside the cylinder flows upward through the glue outlet pipe and the glue outlet valve in turn, which is beneficial to maintaining the stability of the pressure in the cylinder, avoiding the situation where the change of internal glue amount affects the glue supply pressure, and improving the stability of glue supply, thereby improving the overall glue supply quality.

[0052] Furthermore, the first stirring blade and the second stirring blade are both inclined. When the stirring rod rotates, the first stirring blade and the second stirring blade can push the glue inside the cylinder obliquely upward. The stirring rod is driven to rotate by the rotating shaft, so that the inclined first stirring blade and the second stirring blade can push the glue inside the cylinder obliquely upward during the rotation, thereby fully mixing the glue at the bottom layer inside the cylinder with the glue at the upper layer, reducing the deposition of particles at the bottom of the cylinder, which is beneficial to improving the uniformity of distribution of particles in the glue and improving the quality of the glue.
