Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of adhesive processing, in particular to an adhesive heating and stirring device. Background Art
[0002] Due to its unique viscosity and polymer structure, adhesives have poor fluidity at room temperature. This makes it easy for adhesives to accumulate and entangle on the drive shaft during the mixing process, forming glue lumps that are difficult to clean. These glue lumps not only affect the mixing effect, but may also cause blockage and damage to the drive shaft, increasing the failure rate and maintenance costs during the production process. In addition, the poor fluidity of adhesives may also cause excessive bubbles and impurities during the mixing process, further affecting the performance and quality of the finished product.
[0003] The commonly used mixing devices on the market currently include forced mixing devices, single-horizontal-shaft mixing devices, and double-horizontal-shaft mixing devices. These devices mainly rely on the rotation of the drive shaft and the mixing blades to mix the materials during the mixing process. However, for adhesives with poor fluidity, this mixing method often cannot fully mix the materials, especially near the drive shaft and on the back of the mixing blades, which is prone to mixing dead corners and uneven mixing. In addition, since adhesives are prone to accumulation and entanglement on the drive shaft, existing mixing devices are also prone to problems such as blockage and overload during the mixing process, further affecting production efficiency and finished product quality. Utility Model Content
[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an adhesive heating and stirring device. Through this design, the problem that the adhesive is easily accumulated and entangled on the drive shaft during the processing and stirring of the adhesive, which is prone to mixing dead corners and uneven stirring, and in severe cases may even cause blockage and damage to the drive shaft is effectively solved.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the utility model comprises a fixing frame, a glue barrel is vertically placed on the fixing frame, a glue inlet is arranged on the upper end of the glue barrel, a glue outlet is arranged on the side of the lower end of the glue barrel, a protective frame is arranged around the glue barrel, the protective frame is fixedly connected to the fixing frame, fixing plates are fixedly connected to the protective frames on both sides of the glue barrel, a heating tube is fixedly connected to the inner side of the fixing plate, one end of the heating tube is connected to a heater, the heater is located on one side of the glue barrel, and a spiral agitator is rotatably connected in the glue barrel;
[0006] The spiral stirrer comprises a driving shaft, a connecting rod and blades. The blades are of a spiral structure. The driving shaft is located in the middle of the blades. The connecting rods are distributed on the driving shaft along the contour of the blades.
[0007] Preferably, the overall outer contour of the blade is a trapezoidal structure.
[0008] Preferably, a first clamp and a second clamp are fixedly connected to the inner side of the fixing plate, and a groove matching with the rubber barrel is formed in the first clamp and the second clamp.
[0009] Preferably, the heating tube is coiled on the fixing plate in an S shape, and the heating tube is located between the first clamp and the second clamp.
[0010] Preferably, a funnel is fixedly connected to the glue inlet.
[0011] Preferably, a worm wheel is fixedly connected to the bottom of the driving shaft, a worm is meshed with the worm wheel, a driving belt is coaxially fixedly connected to the worm, and the worm wheel and the worm are rotatably mounted in a fixed frame.
[0012] Compared with the prior art, the utility model has the following outstanding advantages:
[0013] The utility model is provided with heating tubes on both sides of the glue barrel. The heating tubes maintain a relatively high temperature inside the glue barrel through heat conduction of the glue barrel, thereby improving the fluidity of the colloid and preventing the adhesive from solidifying into a glue block on the driving shaft. In addition, the blades adopted by the driving shaft are of a spiral structure, and the side wings of the blades can cut the adhesive. At the same time, the spiral structure exerts an upward force on the adhesive when rotating, and has a higher stirring effect on the adhesive than the conventional driving shaft.

[0020] The technical solutions in the embodiments of the utility model are clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0021] Please see attached Figure 1-5 The present embodiment provides an adhesive heating and stirring device, comprising a fixed frame 1, a glue barrel 18 is vertically placed on the fixed frame 1, a glue inlet 2 is provided at the upper end of the glue barrel 18, a glue outlet 3 is provided on the side of the lower end of the glue barrel 18, a protective frame 4 is provided around the glue barrel 18, the protective frame 4 is fixedly connected to the fixed frame 1, a fixing plate 5 is fixedly connected to the protective frame 4 on both sides of the glue barrel 18, a heating tube 6 is fixedly connected to the inner side of the fixing plate 5, one end of the heating tube 6 is connected to a heater 7, the heater 7 is located on one side of the glue barrel 18, and a spiral stirrer is rotatably connected in the glue barrel 18.
[0022] The fixing frame 1 has two layers, the glue barrel 18 and the heater 7 are located on the upper layer of the fixing frame 1. The glue barrel 18 is vertically installed on the upper side of the fixing frame 1. The glue inlet 2 of the glue barrel 18 is located directly above. Due to the poor fluidity of the adhesive, the glue inlet 2 is opened at the upper end of the glue barrel 18 to facilitate the adhesive to fall downward under the action of gravity. The spiral agitator is located at the lower end of the inside of the glue barrel 18. The blades 10 in the spiral agitator are spiral blades 10. The spiral blades 10 can be used to cut and transport the colloid to avoid the adhesive from being entangled or sticking on the agitator, thereby improving the agitator's stirring efficiency for the adhesive. The glue barrel 18 is made of a heat-conducting material as a whole. The protective frame 4 is located around the glue barrel 18, the fixing plate 5 is located on the left and right sides of the glue barrel 18, the heater 7 supplies heat to the heating tube 6, and there is a high-temperature medium in the heater 7. The high-temperature medium is heated by the heater 7 and then transported to the heating tube 6. The high-temperature medium in the heating tube 6 transfers heat to the glue barrel 18 through heat transfer. The heating of the glue barrel 18 can prevent the adhesive inside the glue barrel 18 from adhering to the inner wall of the glue barrel 18, and at the same time, the temperature inside the glue barrel 18 can be increased. The fluidity of the adhesive will increase at high temperature, which is convenient for the stirring work of the spiral stirrer, so that the adhesive in the glue barrel 18 can be stirred more evenly, and the processing efficiency can be improved.
[0023] The spiral agitator includes a drive shaft 8, a connecting rod 9 and a blade 10. The blade 10 is a spiral structure. The drive shaft 8 is located in the middle of the blade 10. The connecting rod 9 is distributed on the drive shaft 8 along the contour of the blade 10. The overall outer contour of the blade 10 is a trapezoidal structure.
[0024] The drive shaft 8 is rotatably connected to the glue barrel 18. The blade 10 has a spiral structure, and there are multiple connecting rods 9. The connecting rods 9 are located between the blade 10 and the drive shaft 8. The connecting rods 9 are spirally distributed on the drive shaft 8. The lateral distance of the upper end of the blade 10 is smaller than the lateral distance of the lower end. The drive shaft 8 drives the blade 10 to rotate counterclockwise. The rotation of the blade 10 will drive the adhesive on the blade 10 to move upward along the contour of the blade 10, thereby moving the adhesive at the bottom of the glue barrel 18 upward. As the blade 10 rises, a part of the adhesive falls from the gap between the drive shaft 8 and the blade 10 to the bottom of the glue barrel 18, and the other part is pushed to the upper layer of the adhesive in the glue barrel 18, so that the adhesive in the glue barrel 18 has greater fluidity. The side of the blade 10 is a thin sheet. Compared with the drive shaft blade 10, it has a better cutting and separation effect on the adhesive, and has a better mixing effect when stirring the adhesive, and has a higher mixing efficiency.
[0025] The structures on the two fixing plates 5 are the same. The first clamp 11 is located at the upper end of the rubber barrel 18, and the second clamp 12 is located at the lower end. The rubber barrel 18 is reinforced by the first clamp 11 and the second clamp 12 to prevent the rubber barrel 18 from tipping over.
[0026] The heating tube 6 is coiled on the fixing plate 5 in an S shape. By increasing the laying length of the heating tube 6 in a limited space, the heating effect of the glue barrel 18 can be improved, the inside of the glue barrel 18 is ensured to be maintained at a higher temperature, and the fluidity of the colloid in the glue barrel 18 is improved.
[0027] In order to facilitate the filling of adhesive into the glue barrel 18, a funnel 14 is installed at the glue inlet 2 of the glue barrel 18, and sealing covers are installed at the funnel 14 and the glue outlet 3. When the adhesive in the glue barrel 18 is mixed, the funnel 14 and the glue outlet 3 are sealed by the sealing cover to prevent the overflow of the glue and internal heat.
[0028] A motor is installed on the lower layer of the fixed frame 1, and a driving belt 17 is connected to the output end of the motor. The driving belt 17 consists of two pulleys and a belt. One of the pulleys in the driving belt 17 is connected to the worm 16. When the motor is working, the driving belt 17 drives the worm 16 to rotate, and the worm 16 drives the worm wheel 15 to rotate. The worm wheel 15 drives the driving shaft 8 in the spiral agitator to rotate and stir. The worm wheel 15 and the worm 16 can reduce the rotation of the driving shaft 8, so that the driving shaft 8 can rotate smoothly in the glue barrel 18.
[0029] The utility model has a novel structure, ingenious conception, and simple and convenient operation. Through this design, the problems that a conventional adhesive heating and stirring device is prone to shaking, difficult to move, occupies a relatively large vertical space when not in use, and the writable area and the height of the teaching board cannot be adjusted are effectively solved.
[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
