Description

Technical Field

[0001] This utility model relates to the field of glue storage tanks, and in particular to a glue storage tank for glue production. Background Technology

[0002] In the glue-making process, the glue storage tank plays a crucial role. It is the core container for the temporary storage and turnover of glue solution, which can stably supply glue to subsequent production stages. At the same time, it can effectively isolate external contamination, ensure the purity of glue solution, help maintain the stability of glue solution quality, and ensure the orderly progress of the glue-making process.

[0003] However, the height of the stirring shaft in existing adhesive storage tanks is fixed and cannot be adjusted according to changes in the adhesive level. This often results in blind spots in the stirring or blades being partially exposed above the liquid surface, affecting the stirring effect. At the same time, single-shaft stirring often only forms unidirectional flow, making it easy for the adhesive components to separate. Because the stirring shaft is single and has a fixed direction, it cannot generate effective convective shearing action, resulting in insufficient particle shearing force and poor uniformity of adhesive mixing. It is difficult to overcome the viscous resistance of the adhesive, affecting the overall quality of the adhesive and the stirring efficiency. Utility Model Content

[0004] To overcome the problems of existing rubber storage tanks with fixed agitator shaft height, single-shaft agitation easily leads to unidirectional flow, cannot be adjusted with liquid level, and has insufficient shear force, resulting in poor mixing uniformity.

[0005] The technical solution of this utility model is as follows: a glue storage tank for glue production, including a horizontally arranged base plate and support legs fixed to the bottom surface of the base plate. The top surface of the base plate has a first groove and a second groove parallel to each other. A linear moving mechanism is provided in the first groove, and a sliding guide mechanism that is synchronously linked with the linear moving mechanism is provided in the second groove. The tops of the linear moving mechanism and the sliding guide mechanism jointly support a rigid clamping plate. The clamping plate has an arc-shaped positioning groove adapted to the outer contour of the tank body on its inner side facing the glue storage tank body. The radial clamping and positioning of the glue storage tank body on the base plate is achieved by the synchronous displacement of the clamping plate along the long side of the base plate. A lifting unit is vertically arranged on the side of the base plate. The lifting unit is provided with a lifting plate that can reciprocate in the vertical direction. A dual-shaft stirring unit is provided on the lifting plate. The dual-shaft stirring unit includes two independently rotatable stirring shafts that extend horizontally into the glue storage tank body. Each stirring shaft extends into the glue storage tank body and is equipped with radial stirring blades.

[0006] Preferably, the linear movement mechanism includes a bearing seat 1 disposed on the inner wall of the first groove, a bidirectional lead screw disposed inside the bearing seat 1, a knob disposed at the end of the bidirectional lead screw, and the outer wall of the bidirectional lead screw being threadedly connected to the clamping plate.

[0007] Preferably, the sliding guide mechanism includes a slide rail disposed at the bottom of the second groove, a slider slidably connected on the slide rail, and the end face of the slider being connected to the lower end of the clamping plate.

[0008] Preferably, the lifting unit includes a bracket set on the side of the base plate, a servo motor set on the top of the bracket, a bearing seat two set on the bottom of the bracket, a lifting screw connected to the output shaft of the servo motor set inside the bearing seat two, and the outer wall of the lifting screw threadedly connected to the lifting plate.

[0009] Preferably, guide rods are provided between the supports, and the outer wall of the guide rods is slidably connected to the lifting plate.

[0010] Preferably, the dual-shaft stirring unit includes a rotary motor mounted on a lifting plate, with a stirring shaft one mounted on the output shaft of the rotary motor, a bearing seat three mounted on the lower end of the lifting plate, a stirring shaft two mounted inside the bearing seat three, and a transmission structure between the stirring shaft one and the stirring shaft two.

[0011] Preferably, the transmission structure includes a driving gear disposed on the outer wall of the first stirring shaft and a driven gear disposed on the outer wall of the second stirring shaft, with the driving gear and the driven gear meshing together.

[0012] The beneficial effects of this utility model are:

[0013] The lifting unit provides vertical reciprocating motion, allowing the dual-shaft stirring unit to flexibly adjust its position according to the liquid level, ensuring optimal stirring effect. The two stirring shafts of the dual-shaft stirring unit can rotate independently and move in opposite directions, generating strong convection in the liquid within the tank, accelerating component mixing, and improving stirring efficiency and liquid quality.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] In the existing field of adhesive manufacturing processes, adhesive storage tanks are key equipment, undertaking multiple important functions such as adhesive storage, mixing, and preliminary reaction. Currently, the main structure of commonly used adhesive storage tanks is usually made of metal materials, such as stainless steel, to ensure sufficient strength and corrosion resistance, thereby adapting to the possible chemical properties of the adhesive. From an overall appearance perspective, adhesive storage tanks are generally cylindrical or cubical. This shape design facilitates layout and placement in the production workshop and can also ensure the uniformity of the internal adhesive flow to a certain extent.

[0022] At the top of the adhesive storage tank, a large inlet is installed. The inlet is usually equipped with a sealing cap to prevent external dust, impurities, and other contaminants from entering the tank during the adhesive storage process and affecting the quality of the adhesive. When adding adhesive, operators can open the sealing cap to pour the prepared adhesive raw material or the pre-treated adhesive into the tank. The size of the inlet is designed by taking into account factors such as production scale, frequency of adhesive addition, and ease of operation. For large-scale production, the inlet will be relatively large to allow for the quick and efficient injection of large quantities of adhesive raw material into the tank, reducing addition time and improving production efficiency.

[0023] The bottom of the adhesive storage tank is equipped with a discharge port, which is connected to a discharge pipe. The pipe is usually equipped with a valve to control the flow rate and speed of the adhesive. When the adhesive in the tank needs to be transported to the next production stage, the operator opens the valve, and the adhesive will flow out through the discharge pipe under its own gravity. The design of the discharge pipe takes into account the fluidity of the adhesive and the needs of subsequent equipment to ensure that the adhesive can be transported smoothly and steadily, avoiding problems such as blockage or leakage.

[0024] Regarding the mixing system, existing adhesive storage tanks mostly adopt a single-shaft mixing method. The mixing shaft is generally installed vertically in the center of the adhesive storage tank. The upper end of the mixing shaft is connected to the drive motor through a coupling, and the lower end is connected to the mixing blades. The drive motor is fixed on the bracket at the top of the adhesive storage tank. When the motor starts, it drives the mixing shaft to rotate, which in turn causes the mixing blades to rotate in the adhesive liquid, thereby achieving mixing of the adhesive liquid. The shape and size of the mixing blades are diverse, with paddle-type and turbine-type being common. Paddle-type mixing blades have a simple structure and can generate a certain horizontal flow in the adhesive liquid, allowing the adhesive liquid to be mixed to a certain extent in the horizontal direction. Turbine-type mixing blades can generate stronger shear force and circulating flow, which helps to better disperse and mix the particles or different components in the adhesive liquid.

[0025] However, this single-shaft stirring method has many problems in practical applications. Because the height of the stirring shaft is fixed, it cannot be adjusted according to the change of the adhesive liquid level. During the production process, the liquid level of the adhesive will change due to factors such as the addition of raw materials, reaction consumption, and discharge. When the liquid level of the adhesive is low, some areas of the stirring blades may be exposed outside the liquid surface, causing these stirring blades to be unable to stir the adhesive, thus forming a stirring blind zone in the tank. The existence of the stirring blind zone will prevent the adhesive in this area from being fully mixed with other areas, resulting in uneven adhesive composition and affecting the quality of the final adhesive product. For example, in some adhesive manufacturing processes that require high adhesive uniformity, the stirring blind zone may cause the additive concentration in some adhesives to be too high or too low, thereby affecting the performance indicators such as viscosity and curing speed of the adhesive.

[0026] On the other hand, single-shaft stirring can only form a unidirectional flow pattern. During the rotation of the stirring blades, the surrounding adhesive liquid will be driven to flow in a certain direction. However, due to the single nature of the stirring shaft and stirring blades, this flow pattern is relatively fixed and cannot form an effective convective shearing effect in the tank. The particles in the adhesive liquid are not subjected to sufficient shear force in the unidirectional flow and are difficult to be fully dispersed and broken. For some adhesive liquids containing larger particles or components of different densities, this unidirectional flow can easily lead to the stratification of the adhesive liquid components. For example, in adhesive liquids containing solid particles, the particles may gradually settle to the bottom of the tank due to gravity, while the lighter components will float to the surface, forming obvious stratification, which seriously affects the mixing uniformity of the adhesive liquid.

[0027] Furthermore, because the direction of the stirring shaft and stirring blades is fixed, the flow trajectory of the adhesive in the tank is relatively simple, which cannot overcome the viscous resistance of the adhesive. The adhesive itself has a certain viscosity, and during the stirring process, the viscous resistance will hinder the flow and mixing of the adhesive. The single-shaft stirring method is difficult to generate enough force to overcome this viscous resistance, resulting in insufficient material exchange inside the adhesive. This greatly affects the overall quality of the adhesive and the stirring efficiency. In some adhesive manufacturing processes that require fast and efficient stirring, this inefficient stirring method will prolong production time, increase production costs, and reduce the economic benefits of enterprises.

[0028] Please see Figure 1 - Figure 5This utility model provides an embodiment: a glue storage tank for glue production, including a horizontally arranged base plate 1 and support legs 2 fixed to the bottom surface of the base plate 1. A first groove 3 and a second groove 4 are parallel to each other on the top surface of the base plate 1. A linear moving mechanism is provided in the first groove 3, and a sliding guide mechanism synchronously linked with the linear moving mechanism is provided in the second groove 4. The tops of the linear moving mechanism and the sliding guide mechanism jointly support a rigid clamping plate 5. The clamping plate 5 has an arc-shaped positioning groove 6 adapted to the outer contour of the tank body 25 on its inner side. The radial clamping and positioning of the glue storage tank body 25 on the base plate 1 is achieved by the synchronous displacement of the clamping plate 5 along the long side of the base plate 1. A lifting unit is vertically arranged on the side of the base plate 1. The container is equipped with a lifting plate 7 that can reciprocate vertically. The lifting plate 7 has a dual-shaft stirring unit, which includes two independently rotatable stirring shafts that extend horizontally into the container body 25. Each stirring shaft extends into the container body 25 and is equipped with radial stirring blades 8. The base plate 1 is horizontally positioned, serving as the supporting platform for the entire glue-making container. The first groove 3 provides installation space and a guide rail for the linear movement mechanism, ensuring that the container body 25 can be stably and reliably clamped on the base plate 1. The second groove 4 provides installation and movement space for the sliding guide mechanism, which is synchronously linked with the linear movement mechanism to guide the movement direction of the clamping plate 5, ensuring that the clamping plate 5 moves smoothly and reliably. During the process, the movement maintains a straight line to avoid deviation or shaking. The clamping plate 5 is a component that directly clamps and positions the glue storage tank body 25. Through synchronous displacement along the long side of the base plate 1, the clamping or releasing operation of the glue storage tank body 25 is achieved. The design of the arc-shaped positioning groove 6 increases the contact area between the clamping plate 5 and the glue storage tank body 25, so that the clamping force can be more evenly distributed on the outer wall of the glue storage tank body 25, improving the stability and reliability of clamping. At the same time, the arc-shaped positioning groove 6 can also position the glue storage tank body 25, preventing the glue storage tank body 25 from moving or rotating horizontally during clamping, ensuring that the glue storage tank body 25 can maintain a stable position during stirring, which is beneficial. The dual-shaft stirring unit uniformly stirs the adhesive solution, while the lifting unit provides vertical reciprocating motion power to drive the lifting plate 7 to perform lifting operations. The lifting unit provides a height adjustment function for the dual-shaft stirring unit, allowing it to flexibly adjust according to the liquid level of the adhesive solution in the storage tank body 25. This ensures that the stirring shaft and stirring blades 8 are always in a suitable stirring position, improving the stirring effect. The dual-shaft stirring unit includes two independently rotatable stirring shafts that extend horizontally into the storage tank body 25. The two stirring shafts can rotate in opposite directions, causing convection in the adhesive solution within the storage tank body 25. This accelerates the mixing of the components in the adhesive solution, generates shear force, further refines the particles in the adhesive solution, and improves the quality of the adhesive solution.

[0029] Please see Figure 3In this embodiment, the linear movement mechanism includes a bearing seat 9 disposed on the inner wall of the first groove 3, a bidirectional lead screw 10 disposed inside the bearing seat 9, a knob 11 disposed at the end of the bidirectional lead screw 10, and the outer wall of the bidirectional lead screw 10 threadedly connected to the clamping plate 5. The sliding guide mechanism includes a slide rail 12 disposed at the bottom of the second groove 4, a slider 13 slidably connected to the slide rail 12, and the end face of the slider 13 connected to the lower end of the clamping plate 5. The bearing seat 9 is used to provide stable support and precise rotational positioning for the bidirectional lead screw 10. The bearing seat 9 is equipped with a high-precision bearing that can withstand the radial and axial forces generated by the bidirectional lead screw 10 during rotation, ensuring the coaxiality and stability of the bidirectional lead screw 10 during rotation. The bidirectional lead screw 10 has a special thread design, with the threads in opposite directions at both ends of the lead screw. When rotated by the knob 11... When the bidirectional lead screw 10 is in operation, due to the transmission effect of the thread, the clamping plate 5, which is threadedly connected to the bidirectional lead screw 10, will move synchronously towards both ends or the middle of the bidirectional lead screw 10 depending on the direction of rotation. For example, when the bidirectional lead screw 10 is rotated clockwise, the clamping plate 5 will separate towards both ends of the bidirectional lead screw 10, and when the bidirectional lead screw 10 is rotated counterclockwise, the clamping plate 5 will move towards the middle of the bidirectional lead screw 10. This bidirectional movement characteristic allows the clamping plate 5 to conveniently and quickly clamp or release the glue storage tank body 25, meeting the positioning requirements of glue storage tank bodies 25 of different sizes. The slide rail 12 provides a track for the sliding of the slider 13. When the bidirectional lead screw 10 rotates and drives the clamping plate 5 to move, the slider 13 will slide together with the clamping plate 5 on the slide rail 12, providing guidance and support for the movement of the clamping plate 5, making the movement of the clamping plate 5 more stable and reliable.

[0030] Please see Figure 4 In this embodiment, the lifting unit includes a bracket 14 disposed on the side of the base plate 1. A servo motor 15 is disposed on the top of the bracket 14, and a bearing seat 16 is disposed on the bottom of the bracket 14. A lifting screw 17 connected to the output shaft of the servo motor 15 is disposed inside the bearing seat 16. The outer wall of the lifting screw 17 is threadedly connected to the lifting plate 7. A guide rod 18 is disposed between the brackets 14. The outer wall of the guide rod 18 is slidably connected to the lifting plate 7. The bracket 14 provides an installation frame and support structure for the lifting unit. The servo motor 15 is the power source of the lifting unit. By controlling the forward and reverse rotation of the servo motor 15, the lifting is controlled. The screw 17 rotates in both directions. Bearings are installed inside the bearing housing 16, providing stable rotational support for the lifting screw 17 and ensuring its coaxiality and stability during rotation. The outer wall of the lifting screw 17 is threadedly connected to the lifting plate 7. When the servo motor 15 drives the lifting screw 17 to rotate, the lifting plate 7 will move vertically in a straight line along the axis of the lifting screw 17 due to the transmission effect of the thread. The guide rod 18 is used to guide the lifting movement of the lifting plate 7, preventing the lifting plate 7 from rotating or swaying during the lifting process, and ensuring that the lifting plate 7 can only move in a straight line in the vertical direction.

[0031] Please see Figure 5 In this embodiment, the dual-shaft stirring unit includes a rotary motor 19 mounted on a lifting plate 7. A stirring shaft 20 is mounted on the output shaft of the rotary motor 19. A bearing housing 21 is located at the lower end of the lifting plate 7, and a stirring shaft 22 is housed within the bearing housing 21. A transmission structure is provided between the stirring shaft 20 and the stirring shaft 22. The transmission structure includes a driving gear 23 mounted on the outer wall of the stirring shaft 20 and a driven gear 24 mounted on the outer wall of the stirring shaft 22. The driving gear 23 and the driven gear 24 are meshed together. The rotary motor 19 is the power source for the dual-shaft stirring unit. The stirring shaft 20 is mounted on the output shaft of the rotary motor 19. As the rotary motor 19 rotates... The stirring shaft 22 is supported and positioned by the bearing seat 21. Both the stirring shaft 20 and the stirring shaft 22 are equipped with stirring blades 8 on their outer walls for stirring the adhesive. When the stirring shaft 20 rotates, the driving gear 23 rotates synchronously. When the driving gear 23 rotates, the rotational torque and motion are transmitted to the driven gear 24 through the meshing of the gears, which in turn drives the stirring shaft 22 to rotate. Through the cooperation of the driving gear 23 and the driven gear 24, the stirring shaft 20 and the stirring shaft 22 can rotate at the same speed and direction, and jointly stir the adhesive in the adhesive storage tank body 25, thereby improving the stirring effect and uniformity.

[0032] Working principle: First, the glue storage tank body 25 is placed on the base plate 1. By rotating the knob 11 of the bidirectional lead screw 10, the clamping plate 5 of the linear moving mechanism is driven to move synchronously along the first groove 3. At the same time, the slider 13 of the sliding guide mechanism slides on the slide rail 12 of the second groove 4 to provide guidance and support for the clamping plate 5, ensuring that the clamping plate 5 moves stably and linearly, thereby realizing the radial clamping and positioning of the glue storage tank body 25. The design of the arc-shaped positioning groove 6 ensures the stability and reliability of the clamping.

[0033] Next, the servo motor 15 of the lifting unit is started, which drives the lifting screw 17 to rotate. Due to the transmission effect of the screw, the lifting plate 7 moves in a straight line along the guide rod 18 in the vertical direction. According to the liquid level of the glue in the glue tank body 25, the position of the dual-shaft stirring unit is flexibly adjusted to ensure that the stirring shaft and stirring blade 8 are in the optimal stirring position.

[0034] Finally, the rotary motor 19 of the dual-shaft stirring unit is started, and the stirring shaft 20 rotates accordingly. Through the driving gear 23 and driven gear 24 of the transmission structure, the stirring shaft 22 rotates synchronously. The two stirring shafts stir in the glue storage tank body 25 at the same speed and direction, generating convection and shear force, accelerating the mixing of various components in the glue, further refining the particles in the glue, and improving the quality and stirring effect of the glue.

[0035] Through the above steps, the lifting unit provides vertical reciprocating motion, allowing the dual-shaft stirring unit to flexibly adjust its position and ensure the best stirring effect. The dual-shaft stirring shafts rotate independently and move in opposite directions, promoting the convection of the adhesive liquid, accelerating mixing, and improving efficiency and quality. This solves the problems of existing adhesive storage tanks where the stirring shaft height is fixed, single-shaft stirring easily forms unidirectional flow, cannot be adjusted with the liquid level, and has insufficient shear force, resulting in poor mixing uniformity.
