Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to a feeding device for proportioning vinyl ester resin. Background Art

[0002] Vinyl ester resin, also known as epoxy acrylate resin, is obtained by esterification reaction of epoxy resin and acrylic acid or methacrylic acid. Epoxy acrylate resin is currently the most widely used and largest-volume photocurable oligomer. Its photocuring speed is the fastest among all types of oligomers, and its cured coating film has the characteristics of high hardness, good gloss, corrosion resistance, heat resistance and excellent electrochemical properties.

[0003] The existing feeder opens the valve on the feeding pipe to directly release the vinyl ester resin raw material in the hopper, and the cross-section of the hopper is gradually reduced, so that a large amount of vinyl ester resin raw material will be accumulated in the feeding pipe, resulting in blockage of the feeding pipe. At the same time, the direct opening of the valve will feed the vinyl ester resin raw material all at once, resulting in excessive feeding affecting the production quality of the vinyl ester resin. Therefore, a feeder for vinyl ester resin proportioning is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a feeder for proportioning vinyl ester resin, which has the advantage of uniform and intermittent feeding.

[0005] In order to achieve the purpose of uniform intermittent feeding, the utility model provides the following technical solutions: a feeder for proportioning vinyl ester resin, comprising a feed pipe, the top of which is fixedly connected to a hopper communicating with the inner cavity of the feed pipe, a mounting frame fixedly mounted on the front wall and the rear wall of the feed pipe, and a vibration release component for uniformly and intermittently feeding the raw materials of the vinyl ester resin is arranged on the feed pipe and the mounting frame;

[0006] The vibration release assembly includes a movable shaft, a crankshaft, an eccentric block, a synchronous wheel, a synchronous belt, a release plate, a movable rod and a motor. The movable shaft is rotatably connected to the front wall and the rear wall of the feeding pipe, and the crankshaft is rotatably connected between the opposite sides of the mounting frame on the front and rear sides. The eccentric block is fixedly mounted on the outer surface of the movable shaft, the synchronous wheel is fixedly mounted on the outer surfaces of the movable shaft and the crankshaft, the synchronous belt is transmission-connected to the outer surface of the synchronous wheel, the release plate is slidably connected in the feeding pipe, the movable rod is hinged on the side wall of the release plate and is rotatably connected to the outer surface of the crankshaft, the motor is fixedly mounted on the front wall of the mounting frame, and the output shaft of the motor is fixedly mounted on the movable shaft.

[0007] Furthermore, the feeding pipe has a U-shape when viewed from above, the mounting frame has an L-shape on the side, and the movable shaft is rotatably connected to the mounting frame.

[0008] Furthermore, the eccentric block is fan-shaped, and a connecting seat hinged to the movable rod is fixedly mounted on the side wall of the release plate.

[0009] Furthermore, the side wall of the feeding pipe is provided with a through hole for the release plate to pass through, and the front side wall and the rear side wall of the feeding pipe are both provided with slots corresponding to the release plate.

[0010] Furthermore, the outer surface of the hopper is fixedly connected with ribs, and the ribs are evenly distributed on four sides of the hopper.

[0011] Compared with the prior art, the utility model provides a feeder for proportioning vinyl ester resin, which has the following beneficial effects:

[0012] The vinyl ester resin proportioning feeder is provided with a vibration release component. After the vibration release component is used, under the synchronous transmission of the synchronous wheel and the synchronous belt, the movable shaft and the crankshaft rotate simultaneously, the rotation of the eccentric block generates centrifugal force to obtain an exciting force to vibrate the feeding pipe and the hopper, triggering the vibration of the vinyl ester resin raw material in the feeding pipe and the hopper, thereby achieving uniform feeding of the vinyl ester resin raw material and reducing the blockage of the vinyl ester resin raw material in the hopper. At the same time, under the rotation of the crankshaft and the connection of the movable rod, the release plate can be pushed to move reciprocatingly horizontally, thereby achieving intermittent feeding of the vinyl ester resin raw material and reducing the impact of excessive feeding on the production quality of the vinyl ester resin.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 A feeder for proportioning vinyl ester resin comprises a feed pipe 1, which is in the shape of a U in top view, and a hopper 2 which is in communication with the inner cavity of the feed pipe 1 and is fixedly connected to the top of the feed pipe 1 for storing vinyl ester resin raw materials, and mounting frames 3 are fixedly installed on the front and rear walls of the feed pipe 1, and the side shape of the mounting frame 3 is L-shaped, and ribs 7 are fixedly connected to the outer surface of the hopper 2 to improve the supporting strength of the outer surface of the hopper 2, and the ribs 7 are evenly distributed on the four sides of the hopper 2.

[0020] See also Figure 2-4 A vibration release assembly 4 for uniformly and intermittently feeding the raw material of the vinyl ester resin is arranged on the feeding pipe 1 and the mounting frame 3. The vibration release assembly 4 includes a movable shaft 41, a crankshaft 42, an eccentric block 43, a synchronous wheel 44, a synchronous belt 45, a release plate 46, a movable rod 47 and a motor 48. The movable shaft 41 is rotatably connected to the front wall and the rear wall of the feeding pipe 1, the movable shaft 41 is rotatably connected to the mounting frame 3, the crankshaft 42 is rotatably connected between the opposite sides of the mounting frames 3 on the front and rear sides, and the eccentric block 43 is fixedly installed on the outer surface of the movable shaft 41. The eccentric block 43 can rotate with the movable shaft 41. The rotation of the eccentric block 43 generates centrifugal force to obtain an exciting force, which causes the feeding pipe 1 and the hopper 2 to vibrate, thereby reducing the blockage of the vinyl ester resin raw material in the feeding pipe 1 and the hopper 2. The shape of the eccentric block 43 is a fan.

[0021] In addition, the synchronous wheel 44 is fixedly installed on the outer surfaces of the movable shaft 41 and the crankshaft 42, and the synchronous belt 45 is connected to the outer surface of the synchronous wheel 44. Under the transmission of the synchronous wheel 44 and the synchronous belt 45, only one motor 48 can realize the simultaneous rotation of the movable shaft 41 and the crankshaft 42, which is highly efficient and energy-saving, and is also conducive to simultaneous vibration and intermittent feeding.

[0022] At the same time, the release plate 46 is slidably connected in the feeding pipe 1, and the release plate 46 moves laterally in the feeding pipe 1. The side wall of the feeding pipe 1 is provided with a through hole 5 for the release plate 46 to pass through. The front side wall and the rear side wall of the feeding pipe 1 are both provided with a slot 6 corresponding to the release plate 46. The through hole 5 and the slot 6 are connected to each other. The movable rod 47 is hinged on the side wall of the release plate 46 and is rotatably connected to the outer surface of the crankshaft 42. The rotation of the crankshaft 42 drives the movable rod 47 to move accordingly, thereby pushing the release plate 46 to reciprocate laterally to achieve intermittent release of the vinyl ester resin raw material. The side wall of the release plate 46 is fixedly installed with a connecting seat hinged to the movable rod 47. The motor 48 is fixedly installed on the front wall of the mounting frame 3. The output shaft of the motor 48 is fixedly installed on the movable shaft 41. When the motor 48 is started, the movable shaft 41 rotates, and uniform intermittent feeding is gradually performed.

[0023] When this embodiment is in use, the motor 48 is started, and under the synchronous transmission of the synchronous wheel 44 and the synchronous belt 45, the movable shaft 41 and the crankshaft 42 rotate at the same time, and the movable shaft 41 drives the eccentric block 43 to rotate. Under the connection between the movable rod 47, the crankshaft 42 and the release plate 46, the movable rod 47 drives the release plate 46 to move back and forth horizontally, so that the feeding pipe 1 and the hopper 2 are intermittently fed while vibrating, thereby ensuring the smooth feeding work and reducing the impact of excessive feeding on the production quality of vinyl ester resin.

[0024] The beneficial effects of the above embodiments are:

[0025] The vinyl ester resin proportioning feeder is provided with a vibration release component 4. After the vibration release component 4 is used, under the synchronous transmission of the synchronous wheel 44 and the synchronous belt 45, the movable shaft 41 and the crankshaft 42 rotate simultaneously, and the eccentric block 43 rotates to generate centrifugal force to obtain an exciting force to vibrate the feeding pipe 1 and the hopper 2, thereby triggering the vibration of the vinyl ester resin raw material in the feeding pipe 1 and the hopper 2, thereby achieving uniform feeding of the vinyl ester resin raw material and reducing the blockage of the vinyl ester resin raw material in the hopper 2. At the same time, under the rotation of the crankshaft 42 and the connection of the movable rod 47, the release plate 46 can be pushed to move back and forth laterally, thereby achieving intermittent feeding of the vinyl ester resin raw material and reducing the impact of excessive feeding on the production quality of the vinyl ester resin.
