Description

Technical Field

[0001] This utility model relates to the field of injection molding material feeding technology, and more specifically, to a window frame injection molding material feeding device. Background Technology

[0002] In the field of injection molding production, feeding raw materials into the injection molding machine is a key link to ensure continuous production. At present, most existing injection molding raw material feeding devices adopt a fixed design (such as welding or a large number of bolts fastening), that is, the feeding device is fixedly installed above the hopper of the injection molding machine.

[0003] In actual production, material blockage can occur in the feeding device. Once blockage occurs, because the feeding device is fixed in position to the injection molding machine, maintenance personnel need to spend time disassembling and cleaning it. During this time, the injection molding machine cannot receive raw materials and must be forced to stop, leading to production interruptions, reduced efficiency, and potential issues such as equipment cooling and mold temperature fluctuations due to prolonged downtime, which can affect product quality. Therefore, we have made improvements and proposed a new material feeding device for window frame injection molding. Utility Model Content

A motor is connected to the side of the end cover away from the toothed box, and the output shaft of the motor is connected to a first toothed rod.

[0010] As a preferred technical solution of this application, the toothed box is rotatably connected to two second toothed rods via bearings. One end of each of the two second toothed rods is connected to a transmission gear located inside the toothed box. One of the transmission gears has a first toothed groove that is inserted into the first toothed rod, and the two transmission gears mesh with each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the scheme of this application:

[0016] This application utilizes a fixed fastener that can be installed onto the injection molding machine to connect the application and ensure its stability during use. In case of material blockage, loosening the second hand-tightening bolt allows the insert rod to separate from the sleeve, enabling the support component and feeding mechanism to be quickly removed from the injection molding machine. This avoids prolonged machine downtime due to feeding device maintenance. During maintenance, manual feeding can be temporarily used to maintain the raw material supply, ensuring continuous production and reducing production cost losses caused by downtime. Because the feeding device is movable, maintenance personnel can perform maintenance in a more spacious and suitable environment, eliminating the need to operate in the confined space next to the injection molding machine, thus reducing maintenance difficulty.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] For an example, please refer to... Figures 1-6 A window frame injection molding material feeding device includes a base 1, a support member on the top of the base 1, a feeding mechanism 2 connected to the support member, the feeding mechanism 2 including an auger conveyor connected to the support member, the auger conveyor connected to a storage hopper 222, a fixing member installed on the side of the support member, the fixing member including a sleeve 106 set on the support member, an insert rod 107 inserted into the inner wall of the sleeve 106, a mounting plate 108 fixedly connected to one end of the insert rod 107, the mounting plate 108 and the insert rod 107 are welded together, the mounting plate 108 is provided with a plurality of mounting holes, a second hand-tightening bolt 109 is threadedly connected to the side of the sleeve 106, one end of the second hand-tightening bolt 109 extends into the sleeve 106 and abuts against the side of the insert rod 107; the sleeve 106 is welded to the side of a column 102;

[0030] When material blockage occurs, loosening the second hand-tightening bolt 109 allows the insertion rod 107 to separate from the sleeve 106, enabling the support components and feeding mechanism 2 to be quickly moved away from the injection molding machine. This avoids prolonged machine downtime due to feeding device maintenance. During maintenance, manual feeding can be temporarily used to maintain the raw material supply to the injection molding machine, ensuring continuous production and reducing production cost losses caused by downtime. Since the feeding device is movable, maintenance personnel can perform maintenance on the feeding device in a more spacious and suitable environment, without having to operate in the confined space next to the injection molding machine, thus reducing maintenance difficulty. After the material blockage repair is completed, the insertion rod 107 is reconnected to the sleeve 106, and then the second hand-tightening bolt 109 is tightened.

[0031] Furthermore, the bottom of the base 1 is provided with wheels 101, which are bolted to the bottom of the base 1. The wheels 101 facilitate the movement of this application.

[0032] Furthermore, the support component includes a column 102 fixedly installed on the top of the base 1. A circular channel is provided in the middle of the column 102, and a support rod 103 is inserted into the inner wall of the circular channel. The top end of the support rod 103 is connected to the auger conveyor. The column 102 is welded to the top of the base 1. Several first hand-tightening bolts 104 are threadedly connected to the side of the column 102. One end of the first hand-tightening bolt 104 extends into the circular channel and abuts against the side of the support rod 103. Tightening the first hand-tightening bolt 104 can fix the position of the support rod 103, while loosening the first hand-tightening bolt 104 can move the support rod 103 up and down and rotate the support rod 103, thereby adjusting the angle and height of the feeding mechanism 2.

[0033] Furthermore, the auger conveying unit includes a connecting seat 201 fixedly installed on the top of the support rod 103. Both sides of the top of the connecting seat 201 are fixedly connected to conveying pipes 202. The tops of the two conveying pipes 202 are connected to a connecting frame 203, and the connecting frame 203 is connected to the bottom of the storage hopper 222. The connecting frame 203 and the storage hopper 222 are connected by bolts. The connecting seat 201, support rod 103, conveying pipes 202 and connecting frame 203 are connected by welding. The storage hopper 222 is used to store raw materials, and the raw materials in the storage hopper 222 enter the conveying pipe 202 through the connecting frame 203.

[0034] Furthermore, a toothed box 204 is provided between one end of the two conveying pipes 202. An end cover 205 is provided on the side of the toothed box 204 away from the conveying pipe 202. A motor 206 is connected to the side of the end cover 205 away from the toothed box 204. The output shaft of the motor 206 is connected to a first toothed rod 207. A bearing is provided between the outer surface of the first toothed rod 207 and the end cover 205. The end cover 205 and the toothed box 204 are connected by bolts. The motor 206 is mounted on the end cover 205 by bolts.

[0035] Furthermore, two second toothed rods 210 are rotatably connected to the gearbox 204 via bearings. One end of each second toothed rod 210 is connected to a transmission gear 208 located inside the gearbox 204. One of the transmission gears 208 has a first toothed groove 209 that inserts into the first toothed rod 207, and the two transmission gears 208 mesh with each other. The motor 206 can drive the two second toothed rods 210 to rotate through the cooperation of the first toothed rod 207 and the transmission gear 208. The insertion design of the first toothed groove 209 and the first toothed rod 207 can realize the detachable connection between the motor 206 and the corresponding transmission gear 208.

[0036] Furthermore, each of the two conveying pipes 202 is provided with an auger body 211. One end of the auger body 211 has a second toothed groove 212, and the second toothed groove 212 is inserted into the outer surface of the second toothed rod 210. The end of the auger body 211 away from the toothed groove box 204 has a connecting shaft 213. The insertion of the second toothed groove 212 and the second toothed rod 210 can realize the detachable connection between the auger body 211 and the second toothed rod 210, so that the auger body 211 can be removed for cleaning when there is a blockage.

[0037] Furthermore, a baffle 221 is fixedly connected between the ends of the two conveying pipes 202 away from the toothed box 204. The baffle 221 and the conveying pipes 202 are fixedly connected by welding. A slot 214 is provided on the baffle 221. A support plate 216 is inserted into the inner wall of the slot 214. Two support bearings 217 are installed on the support plate 216. The inner wall of the support bearings 217 is inserted into the connecting shaft 213. The support plate 216 and the support bearings 217 cooperate with each other to support the connecting shaft 213, thereby improving the stability of the auger body 211 when rotating. The support plate 216 has a discharge port.

[0038] Furthermore, a discharge pipe 218 is hinged to the side of the baffle 221 away from the conveying pipe 202. A stop rod 223 is fixedly installed inside the discharge pipe 218. The stop rod 223 is fixedly installed inside the discharge pipe 218 by welding. The stop rod 223 contacts the support plate 216 and is used to limit the support plate 216. A third hand-tightening bolt 219 is inserted and connected to the discharge pipe 218. A threaded hole 220 is opened on the baffle 221, and the inner wall of the threaded hole 220 is threadedly connected to the third hand-tightening bolt 219.

[0039] In use, a plate with screw holes can be welded onto the injection molding machine. After the bolts pass through the mounting holes on the mounting plate 108, they are connected to the screw holes to realize the connection between this application and the injection molding machine. Alternatively, the mounting plate 108 can be directly welded onto the injection molding machine. Or, holes can be drilled directly on the housing of the injection molding machine and the mounting plate 108 can be installed by bolts.

[0040] The raw materials are stored in the storage hopper 222, away from the inlet conveying pipe 202. The motor 206 drives the auger body 211 to rotate through the transmission of multiple components such as the first toothed rod 207, the transmission gear 208, the first toothed groove 209, and the second toothed rod 210. This drives the raw materials in the conveying pipe 202 to be discharged from the outlet on the support plate 216 to the discharge pipe 218, and then fall into the feed hopper of the injection molding machine from the discharge pipe 218, thus completing the feeding process.

[0041] When the feeding mechanism 2 is being repaired for blockage, the material is tilted to empty the material in the storage hopper 222, and the material that can be poured out of the connecting frame 203 and the conveying pipe 202 is also poured out. Then, the third hand-tightening bolt 219 is unscrewed, and the discharge pipe 218 is rotated to open it, causing the stop bar 223 to separate from the support plate 216. The support plate 216 is pulled outward to remove it, and then the connecting shaft 213 is pulled outward to separate the second toothed groove 212 from the second toothed rod 210, thereby removing the auger body 211. Remove the material from the conveying pipe 202 and clean the residue inside the conveying pipe 202 and on the auger body 211. After cleaning, insert the auger body 211 into the conveying pipe 202 so that the second toothed groove 212 and the second toothed rod 210 are connected. Then, install the support plate 216 into the slot 214 so that the connecting shaft 213 and the support bearing 217 are connected. Then, rotate the discharge pipe 218 back to its original position and screw the third hand-tightening bolt 219 onto the discharge pipe 218 and the threaded hole 220.
