Description

Technical Field

[0001] This utility model relates to the field of screw feeder technology, and in particular to an anti-clogging screw feeder for polyurea raw material pretreatment. Background Technology

[0002] A screw feeder is a device used to convey powdery, granular, or small lump materials. It mainly consists of screw blades, a trough, a drive unit, and inlet and outlet ports. Its working principle is to use the rotation of the screw blades to push the material along the trough to achieve continuous conveying. A screw feeder for polyurea raw material pretreatment is a feeding device used to convey polyurea raw materials to a designated position during the polyurea raw material processing.

[0003] Existing screw feeders generally adopt a one-time feeding design during actual feeding, meaning that regardless of the amount of material, it is all piled up and conveyed at once. This can easily lead to blockages due to excessive material. In addition, the conveying components inside existing screw feeders are generally designed as a single piece, making it inconvenient to maintain and clean the conveying cavity.

[0004] Therefore, in view of the problems of easy clogging and inconvenient maintenance and cleaning of the screw feeder in the prior art, the present invention uses a mechanism to enable batch feeding of materials, which effectively avoids the phenomenon of excessive material clogging the device. At the same time, the mechanism makes the conveying component and the device shell detachable, which facilitates the maintenance and cleaning process of the conveying cavity. Utility Model Content

[0007] Preferably, the feeding control mechanism includes a drive motor, a transmission shaft, spiral blades, and a discharge pipe. The drive motor is fixedly installed on the top outer wall of the support base. The output end of the drive motor passes through the side outer wall of the feeding cylinder body and is connected to the transmission shaft. Spiral blades are arranged circumferentially on the outside of the transmission shaft. The discharge pipe is installed on the bottom outer wall of the feeding cylinder body away from the drive motor.

[0008] Preferably, the feeding control mechanism includes a positioning support plate, a drive gear, a driven gear, a support shaft, and baffles. The positioning support plate is fixedly installed on the top outer wall of the support base, and the positioning support plate is connected to the side outer wall of the feeding cylinder body. The drive gear is fixedly installed outside the shaft of the drive motor at the output shaft position. The driven gear is meshed above the drive gear. Both the drive gear and the driven gear are rotatably installed on the side outer wall of the positioning support plate. The side outer wall of the driven gear is connected to one end of the support shaft. The other end of the support shaft passes through one side outer wall of the hopper and is rotatably installed on the other side inner wall of the hopper. Baffles are arranged in a circumferential manner at equal intervals around the outside of the support shaft body located inside the hopper.

[0009] Preferably, the diameter of the rotating circle of the baffle is smaller than the inner diameter of the hopper, and a gap is left between the lowest contact surface of the baffle and the highest contact surface of the spiral blade.

[0010] Preferably, the portable maintenance mechanism includes a cover, a grooved post, an abutment block, and an abutment slot. The outer wall of the feed cylinder body away from the drive motor is set as an open structure, and the cover is installed on the outer wall of the feed cylinder body through a flange assembly.

[0011] Preferably, the feed cylinder body has a viewing window embedded in the outer side wall of the side wall at the position of the contact groove for observing the situation inside the cylinder.

[0012] Preferably, the total length of the drive shaft is the distance from the outer wall of the drive motor output shaft to the bottom of the groove column.

[0013] The beneficial effects of this utility model are:

[0014] 1. The anti-clogging screw feeder for polyurea raw material pretreatment controls the material feeding rate through a mechanism component during use. It is designed to feed material in batches from a one-time accumulation at the beginning. The batch feeding design can effectively control the amount of material fed each time, reduce the risk of polyurea material accumulating in the conveying pipeline, and thus reduce clogging. At the same time, batch feeding can reduce the risk of material blockage at the source, reduce the pressure on processing and transportation equipment, and ensure the safety of the production process. In addition, the mechanism component links this mechanism with the feeding mechanism, resulting in excellent overall energy efficiency.

[0015] 2. The anti-clogging screw feeder for polyurea raw material pretreatment features a detachable design between the conveying component and the feeding cylinder via a mechanism.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5This utility model provides a technical solution: an anti-clogging screw feeder for pretreatment of polyurea raw materials, including a support base frame 1, a feeding cylinder body 2 and a hopper 3. The feeding cylinder body 2 is fixedly installed on the top outer wall of the support base frame 1, and the hopper 3 is installed through the top outer wall of the feeding cylinder body 2. A feeding control mechanism 4 is provided inside the feeding cylinder body 2, a feeding control mechanism 5 is provided on the side of the feeding control mechanism 4, and a portable maintenance mechanism 6 is provided on the side of the feeding cylinder body 2.

[0024] The feeding control mechanism 4 includes a drive motor 401, a transmission shaft 402, a spiral blade 403, and a discharge pipe 404. The drive motor 401 is fixedly installed on the top outer wall of the support base 1. The output end of the drive motor 401 passes through the side outer wall of the feeding cylinder body 2 and is connected to the transmission shaft 402. The spiral blade 403 is arranged in the outer circumference of the transmission shaft 402. The discharge pipe 404 is installed in the bottom outer wall of the feeding cylinder body 2 away from the drive motor 401. The setting of the transmission shaft 402 here facilitates the installation of the spiral blade 403, and the spiral blade 403 achieves the effect of conveying polyurea raw materials through its rotation trajectory.

[0025] The feeding control mechanism 5 includes a positioning support plate 501, a drive gear 502, a driven gear 503, a support shaft 504, and a baffle 505. The positioning support plate 501 is fixedly installed on the top outer wall of the support base 1, and the positioning support plate 501 is connected to the side outer wall of the feeding cylinder body 2. The drive gear 502 is fixedly installed on the outside of the shaft of the drive motor 401 at the output shaft position. The driven gear 503 is meshed on the top of the drive gear 502. Both the drive gear 502 and the driven gear 503 are rotatably installed on the side outer wall of the positioning support plate 501. The side outer wall of the driven gear 503 is connected to one end of the support shaft 504, and the other end of the support shaft 504 passes through one side of the hopper 3. The outer wall is rotatably installed with the inner wall of the other side of the hopper 3. The support shaft 504 inside the hopper 3 is surrounded by baffles 505 at equal intervals. The diameter of the rotating circle of the baffle 505 is smaller than the inner width of the hopper 3. There is a gap between the lowest contact surface of the baffle 505 and the highest contact surface of the spiral blade 403. The setting that the diameter of the rotating circle of the baffle 505 is smaller than the inner width of the hopper 3 allows the baffle 505 to rotate smoothly inside the hopper 3. The design that there is a gap between the lowest contact surface of the baffle 505 and the highest contact surface of the spiral blade 403 indicates that the movement trajectory of the baffle 505 will not interfere with the conveying trajectory of the spiral blade 403.

[0026] The portable maintenance mechanism 6 includes a cover 601, a grooved post 602, an abutment block 603, and an abutment slot 604. The outer side wall of the feed cylinder body 2 away from the drive motor 401 is designed as an open structure, and the cover 601 is mounted on the outer side wall of the feed cylinder body 2 via a flange assembly. The grooved post 602 is rotatably mounted on the inner side wall of the cover 601 at its center position, and a cylindrical slot for engaging the drive shaft 402 is correspondingly provided on the outer side wall of the grooved post 602. The abutment block 603 is fixedly mounted on the outer side wall of the drive shaft 402 away from the cover 601. The abutment block 603 is configured as… The drive motor 401 is shaped like a cross. The outer side wall of the output shaft is provided with an abutment slot 604 for the abutment block 603 to be inserted and installed. The outer side wall of the feed cylinder body 2 at the abutment slot 604 is embedded with a viewing window for observing the situation inside the cylinder. The total length of the drive shaft 402 is the distance from the outer wall of the output shaft of the drive motor 401 to the bottom of the groove column 602. The setting of the viewing window here makes it easy for the operator to observe whether the abutment block 603 and the abutment slot 604 are aligned. The limitation on the total length of the drive shaft 402 makes the drive shaft 402 more stable after it is installed inside the device and will not change its position.

[0027] Working principle: Refer to the instruction manual. Figure 1 - Appendix Figure 4 As shown, when it is necessary to feed and convey polyurea raw materials, the drive motor 401 needs to be turned on. After the drive motor 401 is turned on, its output end rotates and automatically drives the transmission shaft 402 to rotate, which in turn drives the spiral blade 403 to rotate. When the drive motor 401 is turned on, it will also drive the drive gear 502 to rotate, which in turn drives the driven gear 503 to rotate. Subsequently, the rotation of the driven gear 503 will automatically drive the support shaft 504 to rotate, which in turn drives the baffle 505 to rotate.

[0028] At this time, the polyurea raw material is poured into the hopper 3. Then, with the circumferential rotation of the baffle 505, the polyurea raw material will be automatically fed into the feed cylinder body 2 in batches. At the same time, with the rotation of the spiral blade 403, the polyurea raw material will be automatically transported from one side of the feed cylinder body 2 to the other side of the feed cylinder body 2 and discharged to the outside of the device through the discharge pipe 404.

[0029] Refer to the instruction manual. Figure 5As shown, when the spiral blade 403 needs to be removed from the device for maintenance and cleaning, the flange assembly between the feed cylinder body 2 and the cover 601 must first be removed. Then, the cover 601 can be removed directly from the side of the feed cylinder body 2. After removal, the spiral blade 403 and the drive shaft 402 can be taken out from the feed cylinder body 2. During subsequent installation, the end of the drive shaft 402 needs to be inserted into the bottom of the cylindrical groove in the groove post 602. Then, the cover 601 is adjusted to a suitable position and connected to the side of the feed cylinder body 2. Note that during the connection process, it is necessary to observe through the viewing window to ensure that the contact block 603 is inserted into the contact groove 604. After the connection is tightened, the two flanges can be tightened and installed again using the bolt assembly.

[0030] It should be noted that the aforementioned drive motor 401 can be powered by existing operating techniques, whether using a power supply unit or an external wire, both of which are conventional operating techniques and will not be described in detail here.

[0031] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
