Description

Technical Field

[0001] The utility model relates to the field of colloid feeding devices, in particular to a feeding device for low-density potting glue. Background Art

[0002] Low-density potting compound is a filler-free, low-viscosity, semi-soft, single-component, epoxy encapsulant and casting compound. It has excellent heat shock resistance, low heat release, lasting elasticity, good wetting properties, long working time, and fast curing under elevated temperature conditions. It is mainly used for the potting of tightly wound coils and large castings. When producing low-density potting compound, the raw materials are mixed and stirred in a mixing barrel, but they need to be added to the mixing barrel through a feeding device.

[0003] The feeding device is generally symmetrical, such as conical, cylindrical, cylindrical-conical. The types of feeding devices are divided into solid feeding devices, powder and particle feeding devices, and liquid feeding devices. For example, the feeding method of the liquid feeding device mainly relies on gravity feeding, and the material falls by its own weight.

[0004] For viscous liquids, it is easy for raw materials to remain on the inner walls of the container and the feeding device when they fall due to gravity. The residue not only causes waste, but also easily causes blockage over time. If the raw materials adhere to the inner wall of the feeding device for a long time and are not cleaned, it is easy to damage the device. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a feeding device for low-density potting glue to solve the technical problem that the glue is easy to remain in the material barrel and on the discharge pipe.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding device for low-density potting glue, comprising a feeding funnel, a stirring tank body is installed at the bottom of the feeding funnel, and a stirring shaft is installed inside the stirring tank body, the top of the stirring shaft is connected to a motor, a fixed plate is fixed on one side of the feeding funnel, and a rotating rod is movably installed inside the fixed plate, a groove is arranged inside the fixed plate, a first pulley is fixed on the end of the rotating rod, and the first pulley is connected to the first belt, a half gear is fixed on the other end of the rotating rod, a slide plate is movably installed on the top of the fixed plate, a baffle is fixed on one side of the top of the slide plate, a slider is fixed on the bottom of the slide plate, a knocking hammer is movably installed on one side of the feeding funnel, a spring is fixed on the end of the knocking hammer, and the other end of the spring is fixedly connected to the feeding funnel, and the stirring shaft sleeve is provided with a third pulley and a fourth pulley.

[0007] By adopting the above technical solution, knocking causes the remaining materials in the feeding hopper to fall. When the stirring shaft stirs the raw materials, the rotating rod is driven to rotate by the first transmission component. When the rotating rod rotates, the sliding plate is driven to move. When the sliding plate moves, one end of the knocking hammer is squeezed. When the one end of the knocking hammer is squeezed, the spring is simultaneously squeezed. When the half gear does not contact the rack inside the sliding plate, the spring drives the end of the knocking hammer to reset, thereby achieving the purpose of knocking the raw material barrel placed inside the feeding hopper, enabling the raw materials remaining in the barrel to fall. Through vibration, the raw materials adhering to the barrel will fall, reducing the residue of the raw materials in the barrel.

[0008] The present utility model is further configured such that the transmission component includes a first pulley fixed to the end of the rotating rod and a third pulley fixed to the outer wall of the stirring shaft, and the first pulley and the third pulley are connected by a first belt.

[0009] By adopting the above technical solution, through the provided first transmission component, when the stirring shaft rotates, the rotating rod can be driven to rotate by the first transmission component, reducing the use of the motor and ensuring the synchronization of its operation at the same time.

[0010] The present utility model is further configured such that the bottom of the feeding hopper is installed with a movable pipe through a bearing, and the bottom of the movable pipe is movably installed with a discharge pipe, and a scraper is fixed to the inner wall of the movable pipe.

[0011] By adopting the above technical solution, the provided movable pipe can rotate conveniently, so that the scraper scrapes the inner wall of the discharge port of the feeding hopper and can also scrape the inner wall of the discharge pipe, thereby avoiding the problem of raw materials remaining on the inner wall of the discharge port of the feeding hopper and the inner wall of the discharge pipe.

[0012] The present utility model is further configured such that the outer wall of the movable pipe is connected to the stirring shaft through a second transmission component. The second transmission component includes a second pulley sleeved on the outer wall of the movable pipe and a fourth pulley sleeved on the outer wall of the stirring shaft, and the second pulley and the fourth pulley are connected by a second belt.

[0013] By adopting the above technical solution, through the provided second transmission component, when the stirring shaft rotates, the movable pipe can be driven to rotate simultaneously by the second transmission component, enabling the raw materials on the inner wall of the discharge port of the feeding hopper and the inner wall of the discharge pipe to move, and avoiding the raw materials remaining on the inner wall of the discharge port of the feeding hopper and the inner wall of the discharge pipe.

[0014] The present utility model is further configured such that a slider is fixed to the bottom of the sliding plate, and the cross section of the slider is set as a circular protrusion, and a groove is opened at the top of the fixing plate.

[0015] By adopting the above technical solution, through the cooperation of the arranged slider and groove, the problem that the sliding plate separates from the fixed plate when sliding on the top of the fixed plate can be avoided.

[0016] The utility model is further arranged such that one end of the knocking hammer is fixed with a knocking head, and the material of the knocking head is rubber.

[0017] By adopting the above technical solution, the arranged knocking head can better knock the material bucket, and the rubber material can prevent the knocking head from damaging the material bucket.

[0018] In summary, the main beneficial effects of the utility model are as follows:

[0019] 1. In the utility model, by knocking, the remaining materials in the feeding funnel fall off. When the stirring shaft stirs the raw materials, the first transmission component drives the rotating rod to rotate. When the rotating rod rotates, it drives the sliding plate to move. When the sliding plate moves, it squeezes one end of the knocking hammer. When one end of the knocking hammer is squeezed, it simultaneously squeezes the spring. When the half gear does not contact the rack inside the sliding plate, the spring drives the end of the knocking hammer to reset, so as to achieve the purpose of knocking the raw material bucket placed inside the feeding funnel, making the raw materials remaining in the bucket fall off. Through vibration, the raw materials adhering to the inside of the bucket will fall, reducing the remaining raw materials in the bucket;

[0020] 2. In the utility model, by arranging the second transmission component, the movable pipe and the scraper, when the transmission component drives the movable pipe to rotate, the movable pipe drives the scraper to rotate. The rotating scraper can scrape the materials remaining at the discharge port at the bottom of the feeding funnel and on the inner wall of the scraper, preventing the materials from remaining on the inner wall of the scraper at the discharge port.

Detailed implementation manner

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0027] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0028] A feeding device for low-density potting glue, as Figure 1 - Figure 4 shown, includes a feeding funnel 9. The bottom of the feeding funnel 9 is installed with a stirring tank body 18, and a stirring shaft 19 is installed inside the stirring tank body 18. The stirring shaft 19 is sleeved with a third pulley 15 and a fourth pulley 16. The top of the stirring shaft 19 is connected to a motor 17. When the motor 17 works, it drives the stirring shaft 19 to rotate slowly. The stirring shaft 19 mixes the raw materials entering the stirring tank body 18. When the stirring shaft 19 rotates, it drives the third pulley 15 and the fourth pulley 16 to rotate simultaneously. When the third pulley 15 rotates, it drives the first pulley 2 to rotate through the first belt 20. When the first pulley 2 rotates, it drives the rotating rod 1 to rotate. One side of the feeding funnel 9 is fixed with a fixed plate 3, and a rotating rod 1 is movably installed inside the fixed plate 3. A groove 13 is provided inside the fixed plate 3. The end of the rotating rod 1 is fixed with a first pulley 2, and the first pulley 2 is connected to the first belt 20. The other end of the rotating rod 1 is fixed with a half gear 4. A slide plate 5 is movably installed on the top of the fixed plate 3, and a baffle 6 is fixed on one side of the top of the slide plate 5. A slide block 14 is fixed at the bottom of the slide plate 5. When the rotating rod 1 rotates, it drives the half gear 4 to rotate. When the half gear 4 rotates, it meshes with the rack on the inner wall of the slide plate 5, thereby driving the slide plate 5 to move. When the slide plate 5 moves, it drives the baffle 6 to move. A hammer 8 is movably installed on one side of the feeding funnel 9, and a spring 7 is fixed at the end of the hammer 8, and the other end of the spring 7 is fixedly connected to the feeding funnel 9. The baffle 6 contacts the end of the hammer 8, thereby squeezing the hammer 8 to rotate. According to the lever principle, the end of the hammer 8 moves. While the end of the hammer 8 moves, it squeezes the spring 7. When the teeth on the outer wall of the half gear 4 lose contact with the rack on the inner wall of the slide plate 5, the spring 7 drives the hammer 8 to reset. At this time, the hammer 8 will drive the baffle 6 to reset.

[0029] Please refer to Figure 1 - Figure 3 As shown in Figure 3 , the first transmission assembly includes a first pulley 2 fixed to the end of the rotating rod 1 and a third pulley 15 fixed to the outer wall of the stirring shaft 19, and the first pulley 2 and the third pulley 15 are connected by a first belt 20. By setting the first transmission assembly, when the stirring shaft 19 rotates, the rotating rod 1 can be driven to rotate through the first transmission assembly, reducing the use of the motor and ensuring the synchronization of its work at the same time.

[0030] Please refer to Figure 1 - Figure 3 As shown in Figure 3 , a movable pipe 10 is installed at the bottom of the feeding funnel 9 through a bearing, and a discharge pipe 22 is movably installed at the bottom of the movable pipe 10. A scraper 12 is fixed to the inner wall of the movable pipe 10, and the discharge pipe 22 is connected to the stirring tank body 18 through a bearing. By setting the movable pipe 10, it can rotate conveniently, so that the scraper 12 can scrape the inner wall of the discharge port of the feeding funnel 9 and also scrape the inner wall of the discharge pipe 22, thus avoiding the problem that raw materials remain on the inner wall of the discharge port of the feeding funnel 9 and the inner wall of the discharge pipe 22.

[0031] Please refer to Figure 1 - Figure 3 As shown in Figure 3 , the outer wall of the movable pipe 10 is connected to the stirring shaft 19 through a second transmission assembly. The second transmission assembly includes a second pulley 11 sleeved on the outer wall of the movable pipe 10 and a fourth pulley 16 sleeved on the outer wall of the stirring shaft 19, and the second pulley 11 and the fourth pulley 16 are connected by a second belt 21. By setting the second transmission assembly, when the stirring shaft 19 rotates, the movable pipe 10 can be driven to rotate simultaneously through the second transmission assembly, so that the raw materials on the inner wall of the discharge port of the feeding funnel 9 and the inner wall of the discharge pipe 22 can be moved, avoiding the raw materials remaining on the inner wall of the discharge port of the feeding funnel 9 and the inner wall of the discharge pipe 22.

[0032] Please refer to Figure 2 - Figure 4 As shown in Figure 4 , a slider 14 is fixed to the bottom of the sliding plate 5, and the cross section of the slider 14 is set as a circular protrusion. A groove 13 is opened at the top of the fixing plate 3. By setting the slider 14 and the groove 13 to cooperate with each other, the problem that the sliding plate 5 separates from the fixing plate 3 when sliding on the top of the fixing plate 3 can be avoided.

[0033] Please refer to Figure 1 - Figure 3 As shown in Figure 3 , a knocking head 23 is fixed to one end of the knocking hammer 8, and the material of the knocking head 23 is rubber. By setting the knocking head, the material bucket can be knocked better, and the rubber material can avoid damaging the material bucket by the knocking head 23.

[0034] The working principle of the present utility model is as follows: When feeding materials, the raw material barrel is inserted into the feeding funnel 9. Subsequently, the motor 17 operates to drive the stirring shaft 19 to rotate slowly. The stirring shaft 19 mixes the raw materials entering the stirring tank body 18. When the stirring shaft 19 rotates, it drives the third belt pulley 15 and the fourth belt pulley 16 to rotate simultaneously. When the third belt pulley 15 rotates, it drives the first belt pulley 2 to rotate through the first belt 20. When the first belt pulley 2 rotates, it drives the rotating rod 1 to rotate. When the rotating rod 1 rotates, it drives the semi-gear 4 to rotate. When the semi-gear 4 rotates, it meshes with the rack on the inner wall of the slide plate 5, thereby driving the slide plate 5 to move. When the slide plate 5 moves, it drives the baffle 6 to move. The baffle 6 contacts the end of the knocking hammer 8, thereby squeezing the knocking hammer 8 to rotate. According to the lever principle, the end of the knocking hammer 8 moves. While the end of the knocking hammer 8 moves, it squeezes the spring 7. When the teeth on the outer wall of the semi-gear 4 lose contact with the rack on the inner wall of the slide plate 5, the spring 7 drives the knocking hammer 8 to reset. At this time, the knocking hammer 8 will drive the baffle 6 to reset. The end of the knocking hammer 8 knocks on the outer wall of the material barrel, generating vibrations so that the raw materials adhering to the inside of the material barrel can all slide off, avoiding waste. When the fourth belt pulley 16 rotates, it drives the second belt pulley 11 to rotate through the second belt 21. The second belt pulley 11 rotates to drive the movable pipe 10 to rotate simultaneously. When the movable pipe 10 rotates, it drives the scraper 12 to rotate on the inner wall of the discharge port of the feeding funnel 9 and the inner wall of the discharge pipe 22, so that there is no residue on its inner wall either, reducing the waste of materials.
