Description

Technical Field

[0001] The utility model relates to the technical field of plastic rod production, in particular to a plastic rod hot pressing extrusion device. Background Art

[0002] Plastic rods generally refer to solid cylinders. Plastic rods are mainly used like round steel. The production of plastic rods mostly adopts hot pressing extrusion. The plastics used for extrusion molding rods include: polyamide, polyoxymethylene, polycarbonate, ABS, polyphenylene ether, polysulfone, polyethylene, polypropylene, polyvinyl chloride and plexiglass.

[0003] Application No. 202123152789.7 discloses a hot-pressing extrusion device for plastic rods, comprising a support table, an extruder is fixedly connected to an edge of one side of the top surface of the support table, a feeding funnel is installed on the top surface of the extruder, a mouth die is installed on one side of the extruder, a stabilizing mechanism is slidably connected to the middle of the top surface of the support table, a cutting mechanism is provided on one side of the extruder, support legs are fixedly connected to the four corners of the bottom of the support table, universal wheels are fixedly connected to the bottoms of multiple support legs, and a single-chip microcomputer controller is fixedly connected to the corners of one side of the front of the extruder. The extruded plastic rod is stabilized by the stabilizing mechanism to avoid the extruded plastic rod from bending due to its own weight. The extruded plastic rod is extruded through the mouth die and enters a stabilizing cylinder horizontally aligned with it, and then supported by the stabilizing cylinder to keep the shape of the plastic rod unchanged, thereby producing better quality plastic rods.

[0004] The above scheme has shortcomings during use. Since there is no contact between the stabilizing cylinder and the die, when the cutter cuts the plastic rod, the cutter will exert a certain downward pressure on the cut portion of the plastic rod. The cut portion of the plastic rod after cutting may fall and tilt due to the influence of the downward pressure, which may cause the plastic rod to bend. For this reason, we provide a plastic rod hot pressing extrusion device. Utility Model Content

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] First embodiment

[0025] As attached Figure 1 To Attachment Figure 4 As shown: a plastic rod hot pressing extrusion device comprises a bottom plate 1, an extruder 2 is installed on the upper surface of the bottom plate 1, a discharge pipe is installed on the side of the extruder 2 close to the support plate 303, and the discharge pipe is flush with the support plate 303.

[0026] A cutting assembly 3 is installed on the upper surface of the base plate 1. The cutting assembly 3 includes a motor 301 installed on the upper surface of the base plate 1. The two output ends of the motor 301 are fixedly connected to the winding rod 302. A support plate 303 is arranged above the motor 301. The outer surface of the support plate 303 is fixedly connected to two connecting plates 304. A sliding hole 305 is opened on the upper surface of each connecting plate 304. The inner wall of each sliding hole 305 is slidably connected to a sliding rod 306. The top ends of the two sliding rods 306 are commonly fixedly connected to a mounting plate 307. A cutter 308 is installed on the bottom surface of the mounting plate 307. A spring 309 is sleeved on the outer surface of each sliding rod 306. The top end of each spring 309 is connected to the bottom surface of the mounting plate 307. The bottom end of each spring 309 is connected to the upper surface of the connecting plate 304. The outer surface of 302 is wrapped with a connecting rope 310, and the top of each connecting rope 310 is connected to the bottom end of the slide bar 306. The upper surface of the support plate 303 is provided with an arc groove 311. When the motor 301 is working, the winding rod 302 will wind up the connecting rope 310, and the connecting rope 310 will pull the slide bar 306 down. At the same time, the spring 309 will shrink, and the cutter 308 will gradually descend to cut the plastic rod. Since the arc groove 311 is adapted to the cutter 308, the cutter 308 will eventually enter the arc groove 311. After the plastic rod is cut off, both ends will lie flat on the support plate 303, thereby avoiding bending of the two ends of the plastic rod after cutting. When the motor 301 is reversed, the spring 309 will extend and retract to push the mounting plate 307, and the cutter 308 will rise, so that the plastic rod can be repeatedly cut.

[0027] In order to further improve the stability of the support plate 303, two groups of support rods 312 are fixedly connected to the outer surface of the support plate 303, and the bottom end of each support rod 312 is connected to the upper surface of the base plate 1. The connection between the support rod 312 and the base plate 1 can form support for the support plate 303, so that the support plate 303 can be kept level with the extruder 2, thereby improving the stability of the support plate 303.

[0028] The ends of the two winding rods 302 that are away from each other are rotatably connected to a stabilizing plate 313, and the bottom surface of each stabilizing plate 313 is connected to the upper surface of the base plate 1. The stabilizing plate 313 can be used to reinforce the winding rod 302 and the base plate 1, thereby ensuring the stability of the winding rod 302 when rotating, so that the winding rod 302 can stably reel in the connecting rope 310.

[0029] Two supporting rods 314 are fixedly connected to the bottom surface of the mounting plate 307, and a limiting plate 315 is fixedly connected to the outer surface of each sliding rod 306. The supporting rods 314 can limit the descending distance of the mounting plate 307, thereby avoiding collision and bending between the cutter 308 and the arc groove 311. The limiting plate 315 can block the sliding rod 306 to prevent separation between the sliding rod 306 and the connecting plate 304.

[0030] Second embodiment

[0031] A supporting assembly 4 is installed on the upper surface of the base plate 1, and the supporting assembly 4 includes two sockets 401 opened on the upper surface of the base plate 1, and a pillar 402 is inserted into the inner wall of each socket 401, and a supporting plate 403 is fixedly connected to the top of the two pillars 402. The supporting plate 403 can be stabilized by connecting the pillars 402 and the sockets 401, so that the supporting plate 403 can support the extruded plastic rods. At the same time, the supporting plate 403 can be easily disassembled, which is convenient for the staff to clean the supporting plate 403.

[0032] Two stabilizing grooves 404 are provided on the upper surface of the supporting plate 403, and a stabilizing block 405 is inserted into the inner wall of each stabilizing groove 404. The top ends of the two stabilizing blocks 405 are fixedly connected with a cover plate 406. By utilizing the connection between the stabilizing block 405 and the stabilizing groove 404, the cover plate 406 can be stabilized on the supporting plate 403, thereby shielding the upper part of the supporting plate 403 to prevent debris from falling on the extruded plastic rods.

[0033] Working principle: When in use, the plastic rod extruded by the extruder 2 will pass through the support plate 303 and enter between the supporting plate 403 and the cover plate 406. When the plastic rod needs to be cut, the motor 301 is started, and the motor 301 will drive the winding rod 302 to rotate, and the winding rod 302 will wind up the connecting rope 310, and the connecting rope 310 will pull the slide bar 306 downward. At the same time, the mounting plate 307 will drive the cutter 308 to descend, and the mounting plate 307 will squeeze the spring 309. As the mounting plate 307 descends, the cutter 308 will gradually complete the cutting of the plastic rod and enter the arc groove 311, which can prevent the plastic rod from falling and tilting at the cut end, thereby avoiding the bending of the plastic rod.
