[0037] As Figures 1-5As shown, the utility model provides a silica gel feeding device, this silica gel feeding device includes: the material cylinder 1, one end of material cylinder 1 is connected with drive cylinder 2, and the telescopic end of drive cylinder 2 is installed with piston assembly 20, and drive cylinder 2 drives piston assembly 20 to carry out push-pull movement in material cylinder 1;The end away from drive cylinder 2 of material cylinder 1 is installed with feeding cover 21, and feeding cover 21 is equipped with empty hole 210;Fixed frame 3, its upper end is fixed with discharge nozzle 4;Feeding cover 21 is slidably installed between the two sides of fixed frame 3 length direction frame;Drive assembly 5, it is installed in one side end of fixed frame 3, for driving material cylinder 1 relative discharge nozzle 4 carry out the dislocation opening and closing movement.

[0038] The utility model provides a kind of silica gel feeding device, when feeding or changing material, piston assembly 20 is driven by drive cylinder 2 to carry out contraction reset, cylinder 50 drives material cylinder 1 relative displacement discharge nozzle 4, at this time, feeding cover 21 and discharge nozzle 4 dislocation separation, silica gel material is loaded into material cylinder 1 from empty hole 210, finally, material cylinder 1 is reset by cylinder 50 pulling, and material cylinder 1 and discharge nozzle 4 close and pass through connection, quickly complete feeding or changing material operation;Since rubber bowl 202 belongs to vulnerable parts, it needs to be replaced after silica gel device operates certain length of time, when replacing rubber bowl 202, piston assembly 20 is also reset by contraction, and cylinder 50 will drive material cylinder 1 relative displacement discharge nozzle 4 to make them dislocation separation, drive cylinder 2 drives piston assembly 20 to move towards feeding cover 21, finally, rubber bowl 202 can be replaced by disassembly;The silica gel feeding device structure is simple, simplify the work of later maintenance, improve the efficiency of feeding and changing material simultaneously.

[0039] In the embodiment, as shown in Figure 1 And Figure 2 The bottom of material cylinder 1 is installed with feeding base 22, and the end close to material cylinder 1 of drive cylinder 2 is installed with abutment plate 23, four pull rods 24 are connected in rectangle at four corner positions of abutment plate 23, and the end away from abutment plate 23 of four pull rods 24 is respectively threaded feeding base 22 and fixedly connected to feeding cover 21, so that drive cylinder 2, material cylinder 1 and feeding cover 21 are more stably connected on the same axis, so that the stability of the silica gel feeding device is further improved;On the other hand, spring 25 is respectively sleeved on the part of pull rod 24 between feeding base 22 and abutment plate 23, and the two ends of spring 25 are respectively abutted with feeding base 22 and abutment plate 23.

[0040] Further, as shown in Figure 5As shown, the discharge nozzle 4 is in a conical hollow shape, the end with larger diameter of the discharge nozzle 4 is the feeding port, the feeding port is in open and through connection with the feeding cover 21, and the end with smaller diameter of the discharge nozzle 4 is the discharge port; the two sides of the discharge port extend outward to be provided with the connecting portions 40, the connecting portions 40 are provided with a plurality of threaded connection holes; the connecting portions 40 are provided to facilitate the through connection with the injection nozzle of the silicone injection molding equipment; the inner wall of the feeding port of the discharge nozzle 4 is provided with an annular step 41, when the driving cylinder 2 drives the piston assembly 20 to move towards the discharge nozzle 4, the end of the barrel 1 close to the discharge nozzle 4 abuts against the annular step 41, so that a relatively sealed cavity is formed between the barrel 1 and the discharge nozzle 4 to prevent the silicone in the barrel 1 from overflowing. Since the spring 25 is arranged between the feeding base 22 and the abutting plate 23, when the driving cylinder 2 drives the piston assembly 20 to reset and contract, the spring 25 is compressed, the barrel 1 moves downward by a certain distance, so that the end of the barrel 1 is away from the annular step 41 until it is flush with the feeding cover 21; in this way, the driving assembly 5 drives the feeding cover 21 to drive the barrel 1 to be dislocated and separated from the discharge nozzle 4 more smoothly; the structure can not only ensure the sealing between the discharge nozzle 4 and the barrel 1, but also can be dislocated and combined, which is convenient for feeding or replacing materials, and improves the efficiency of the silicone feeding device.

[0041] In the embodiment, as shown in Figure 3 and Figure 4 the driving assembly 5 includes the cylinder 50 mounted on one side end of the fixed frame 3 and the driving frame 51 arranged at the bottom of the feeding cover 21; the telescopic end of the cylinder 50 is mounted with the "Y" shaped connector 52, and the driving frame 51 is in driving connection with the cylinder 50 through the "Y" shaped connector 52. Since the torque of the cylinder 50 when driving the barrel 1 to move is large, the driving frame 51 is arranged in the structure of the right-angled isosceles triangle, so that the connection between the cylinder 50 and the feeding cover 21 is more stable, specifically, the inner walls of the two side frames of the fixed frame 3 are respectively provided with the sliding grooves 30, and the two side edges of the feeding cover 21 are slidably arranged in the sliding grooves 30, under the structure, the cylinder 50 drives the driving frame 51 to drive the feeding cover 21 and the barrel 1 to move left and right on the fixed frame 3 to perform the opening and closing movement relative to the discharge nozzle 4, so that the silicone feeding device can quickly feed or replace materials.

[0042] Further, as shown in Figure 3As shown, the piston assembly 20 includes a mounting seat 201 and a rubber bowl 202, which is detachably installed at the top end of the mounting seat 201 by a clamping and screwing connection. Since the rubber bowl 202 is a consumable part, it needs to be replaced regularly. The detachable installation facilitates the quick replacement of the rubber bowl 202, that is, when the rubber bowl 202 needs to be replaced, the material cylinder 1 and the discharge nozzle 4 are dislocated and separated by driving the material cylinder 1 by the cylinder 50, and the piston assembly 20 is driven upward by the driving cylinder 2 to detach and install the rubber bowl 202, thereby improving the maintenance efficiency of the silica gel feeding device. In this embodiment, the driving cylinder 2 is preferably an oil cylinder, and the rubber bowl 202 is conical. In this way, the conical structure of the discharge nozzle 4 can be better matched to push and pull the feeding.

[0043] Specifically, as shown in the figure, Figure 4 The bottom end of the mounting seat 201 is threadedly connected to the telescopic end of the driving cylinder 2. During the up-down movement of the piston assembly 20 driven by the driving cylinder 2, the pressure of the silica gel material in the material cylinder 1 has a certain pressure deviation, which may cause the piston assembly 20 to rotate left and right, resulting in the risk of falling off of the piston assembly 20. In order to avoid this risk, two or four limiting rods 60 are connected to the mounting seat 201, and a clasp ring 6 is slidably sleeved on the body of the driving cylinder 2, and the other end of the limiting rod 60 is connected to the clasp ring 6. In this way, the limiting rod 60 is slidably arranged in the feeding base 22 and the abutting plate 23, and can slide up and down with the telescopic movement of the driving cylinder 2, ensuring that the piston assembly 20 is separated from the telescopic end of the driving cylinder 2 during the push-pull movement. The stability of the silica gel feeding device is improved.
