For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] See also Figure 1 The utility model provides a glue-spinning device, including a fixed platform 1, a carrying platform 2 arranged below the fixed platform 1, a motor 3 arranged on the fixed platform 1, and a glue-spinning plate 4 driven by the motor 3. The carrying platform 2 is used to place a steel plate, and the glue-spinning plate 4 is located above the carrying platform 2. The motor 3 drives the glue-spinning plate 4 to rotate, and utilizes centrifugal force to spin the glue in the glue-spinning plate 4 to the surface of the steel plate. The edge of the glue-spinning plate 4 is provided with a plurality of guide grooves 41. Preferably, all the guide grooves 41 are combined in a serrated shape. When the glue reaches the edge of the glue-spinning plate 4, it is about to When leaving the glue-spinning disk 4, the glue particles are split into multiple smaller glue particles under the cutting action of the serrated guide grooves 41, and the particle size of the glue is effectively reduced. The utility model drives the glue-spinning disk 4 to rotate by the motor 3, and can realize automatic glue spinning. By arranging the guide grooves 41 on the edge of the glue-spinning disk 4, it can ensure that the particle size of the ejected droplets is small and evenly dispersed, effectively improving the bonding performance of the glue, thereby improving the bonding quality of the steel plate. The overall equipment is easy to operate, and can improve work efficiency while reducing the labor of operators.

[0026] As an embodiment of the utility model, the glue-spinning device also includes a glue supply hose 5, the glue inlet of the glue supply hose 5 is connected to a glue source, and the glue source can be a glue supply barrel filled with glue and a glue pump, the glue inlet of the glue supply hose 5 is connected to the glue pump, the tube body of the glue supply hose 5 is fixed on the fixed platform 1, and the glue outlet of the glue supply hose 5 is arranged above the glue-spinning disk 4. When the glue pump is started, the glue in the glue supply barrel flows from the glue outlet to the glue-spinning disk 4 through the glue supply hose 5, thereby realizing automatic glue supply of the glue-spinning disk 4, replacing manual glue supply, and improving glue supply efficiency. At the same time, the glue outlet is aligned with the glue-spinning disk 4, so that glue can be accurately supplied to the glue-spinning disk 4, which can improve the accuracy of glue supply.

[0027] See also Figure 2 As an embodiment of the utility model, the glue-spinning plate 4 includes a glue storage chamber 42 with an opening at the top, a guide plate 43 arranged at the edge of the opening, and a connecting piece 44 arranged inside the glue storage chamber 42. The connecting piece 44 is connected to the motor 3, and the guide groove 41 is arranged at the edge of the guide plate 43. When working, the glue is first poured into the glue storage chamber 42, the motor 3 is started, and the glue-spinning plate 4 is driven to rotate. The glue flows out of the glue storage chamber 42 under the action of centrifugal force, flows along the guide plate 43 to the guide groove 41 at the edge, and finally, under the action of the guide groove 41, the glue is evenly dispersed on the steel plate below.

[0028] As an embodiment of the utility model, the guide plate 43 is arranged horizontally. After the glue overflows from the glue storage chamber 42, it can buffer the glue and then flow into the guide groove 41, which can avoid splashing of glue and improve the uniformity and controllability of glue spraying. Preferably, the upper surface of the guide plate 43 is a smooth horizontal surface, which can effectively reduce the resistance of the glue on the guide plate 43, and the glue can reach the guide groove 41 more smoothly. At the same time, it can also reduce the residual amount of glue on the guide plate 43, avoiding excessive residual glue causing blockage on the guide plate 43, affecting the glue from flowing to the guide groove 41, affecting the overall automatic glue throwing process, and ultimately affecting the bonding quality of the steel plate.

[0029] When the glue-spinning disk 4 rotates, the glue in the glue storage cavity 42 can flow to the guide plate 43 more smoothly; at the same time, during the glue-spinning process, the glue in the glue storage cavity 42 gradually solidifies and is firmly bonded to the inner wall of the glue storage cavity 42. As the thickness of the glue layer gradually increases, the diameter of the spun droplets also increases, and the bonding effect of the glue also decreases. Therefore, when the droplet diameter cannot meet the bonding requirements, the glue-spinning disk 4 is stopped from use and immersed in a dichloromethane solution for 1-2 days to soften the glue layer before being removed.

[0030] As an embodiment of the utility model, the glue storage cavity 42 is in the shape of an inverted truncated cone, and the glue storage cavity 42 includes a bottom surface and a side surface, the bottom surface is a plane, and the side surface is an arc surface, and the side surface of the glue storage cavity 42 is inclined to open outward, that is, the area of ​​the top opening of the glue storage cavity 42 is larger than the area of ​​the bottom surface. When the thickness of the glue layer in the glue storage cavity 42 is too large, a small wooden crowbar is used to shovel downward along the inclined side surface of the glue storage cavity 42, so that the glue layer and the inner wall of the glue storage cavity 42 can be easily separated, and the small wooden crowbar will not cause damage to the inner wall of the glue storage cavity 42, and there is no need to spend a lot of dichloromethane soaking time, which is environmentally friendly, greatly saves the time for cleaning the glue layer, realizes rapid cleaning of the glue layer, and improves overall work efficiency.

[0031] As an embodiment of the utility model, a chamfer is provided at the connection between the bottom and the side of the glue storage chamber 42, and a chamfer is provided at the connection between the glue storage chamber 42 and the guide plate 43. By providing chamfers at each corner of the glue storage chamber 42, the difficulty of separating the glue layer in the glue storage chamber 42 from the inner wall can be further reduced, thereby further saving manpower and further improving work efficiency.

[0032] As an embodiment of the utility model, the connecting piece 44 is arranged at the bottom center of the glue storage cavity 42. Since the glue spinning disk 4 adopts a regular symmetrical structure, the bottom center of the glue storage cavity 42 and the center of gravity of the entire glue spinning disk 4 are on the same vertical line. Therefore, the connecting axis between the motor 3 and the connecting piece 44 also passes through the center of gravity of the glue spinning disk 4. When the motor 3 drives the glue spinning disk 4 to rotate, the glue spinning disk 4 as a whole can rotate around its own center of gravity, thereby avoiding shaking of the glue spinning disk 4 due to unstable center of gravity during rotation, and effectively improving the overall balance and stability of the glue spinning disk 4.

[0033] As an embodiment of the utility model, the height of the connecting piece 44 is greater than or equal to the height of the glue storage cavity 42, that is, the height of the connecting position between the connecting piece 44 and the motor 3 is greater than or equal to the height of the glue storage cavity 42, so that the glue in the glue storage cavity 42 can only contact the surface of the connecting piece 44, but cannot reach the connecting position between the connecting piece 44 and the motor 3, which can avoid the glue in the glue storage cavity 42 from causing unnecessary influence on the connection relationship between the connecting piece 44 and the motor 3.

[0034] Preferably, the top of the connecting member 44 is connected to the motor 3, the bottom of the connecting member 44 is connected to the glue storage chamber 42, and the side of the connecting member 44 is an outwardly convex arc surface. The use of a non-edge-shaped arc surface can avoid the abnormal phenomenon of glue splashing due to resistance to the flow of glue in the glue storage chamber 42, and can achieve smooth flow of glue in the glue storage chamber 42, improve the uniformity of glue in the glue storage chamber 42, and effectively improve the stability and safety of the glue spinning disk 4.

[0035] As an embodiment of the present utility model, the glue outlet of the glue supply hose 5 is toward the center of the glue spinning disk 4. According to the use requirements, the glue supply hose 5 can supply glue into the glue spinning disk 4 before the motor 3 is started, or it can supply glue into the glue spinning disk 4 in real time during the starting process of the motor 3. In the process of glue supplying by the glue supply hose 5, the glue will more or less exert a certain force on the glue spinning disk 4. For the rotating glue spinning disk 4, if the force exerted by the glue does not pass through the center of gravity of the glue spinning disk 4, the overall force balance of the glue spinning disk 4 will be broken, causing the glue spinning disk 4 to tilt. Therefore, directing the glue outlet of the glue supply hose 5 toward the center of the glue spinning disk 4 can reduce or even avoid the influence of the glue supply on the glue spinning disk 4, thereby improving the overall stability.

[0036] In summary, the utility model provides a glue-spinning device, which can realize automatic glue-spinning by driving the glue-spinning disk 4 to rotate through the motor 3. By setting the guide groove 41 at the edge of the glue-spinning disk 4, it can ensure that the particle size of the spun droplets is small and evenly dispersed, effectively improve the bonding performance of the glue, thereby improving the bonding quality of the steel plate. The overall equipment is easy to operate, and can improve work efficiency while reducing the labor of operators; the glue supply pump and the glue supply hose 5 are used to realize automatic glue supply of the glue-spinning disk 4, replacing manual glue supply, thereby improving the glue supply efficiency; at the same time, the glue outlet is aligned with the glue-spinning disk 4, so that the glue can be accurately supplied to the glue-spinning disk 4, which can improve the accuracy of glue supply; the upper surface of the guide plate 43 is a smooth horizontal surface, which can not only play a buffering role for the glue, but also avoid splashing of the glue, and improve the spraying uniformity and The controllable structure can effectively reduce the resistance of the glue on the guide plate 43, so that the glue can reach the guide groove 41 more smoothly. At the same time, the residual amount of glue on the guide plate 43 can also be reduced, avoiding blockage of the guide plate 43 caused by excessive residual glue; the glue storage chamber 42 is in the shape of an inverted truncated cone, which can easily separate the glue layer and the inner wall of the glue storage chamber 42, without spending a lot of dichloromethane soaking time, which is environmentally friendly, greatly saves the time for cleaning the glue layer, realizes rapid cleaning of the glue layer, and improves the overall work efficiency; the connecting piece 44 is arranged at the bottom center of the glue storage chamber 42, which can realize the rotation of the glue-spinning plate 4 around its own center of gravity, avoiding the shaking of the glue-spinning plate 4 due to unstable center of gravity during the rotation process, and effectively improving the overall balance and stability of the glue-spinning plate 4.
