Description

Technical Field

[0001] This utility model relates to the field of plastic pipe production technology, specifically to an extrusion device for plastic pipe fittings. Background Technology

[0002] An extrusion device, also known as an extruder, is a device typically used in the production and processing of plastic pipes to extrude and shape them.

[0003] A search revealed that patent document CN221717763U discloses a plastic pipe production extrusion device, including an extruder. A feed hopper is fixedly connected to one side of the extruder, and an extrusion tube is fixedly connected to another side. Shearing devices are installed on both sides of the extruder, and a collection device is installed on one side. This invention, by incorporating shearing devices, requires continuous adjustment of the inner wall of the extrusion tube to obtain plastic pipes of the appropriate thickness. During adjustment, two electric telescopic rods can be periodically activated, driving two U-shaped grooved blocks and two screw-hole blades to move in opposite directions, shearing off the extruded waste material from the tube. This prevents blockage at the extrusion tube outlet, which could affect subsequent extrusion molding. It also avoids accidental burns caused by manual removal.

[0004] The above-mentioned patent has the following defects: In high-temperature working environments, the cutting tool, i.e. the screw hole blade, may heat up due to prolonged operation, which not only affects its service life but may also reduce cutting accuracy and efficiency. At the same time, the overheated cutting tool may increase the risk of burns to the operator, especially when replacing or maintaining the cutting tool. Therefore, it cannot meet the usage requirements. Hence, an extrusion device for plastic pipe fittings is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an extrusion device for plastic pipe fittings, which has the advantages of strong practicality, the ability to cool down cutting tools, and improved production efficiency, thus solving the problem of the inability to cool down overheated cutting tools.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an extrusion device for plastic pipe fittings, comprising an extrusion device body and an extrusion tube fixedly connected to the discharge end of the extrusion device body, wherein two cutters, a drive mechanism and a water conveying device are provided on the outside of the extrusion device body;

[0007] The driving mechanism includes a drive motor, a drive disk, and a swing frame. The front of the drive disk is equipped with a roller that is rolledly connected to the inside of the swing frame. The swing frame is fixed with connecting rods on both the left and right sides.

[0008] The water conveying equipment includes a pump body, two check valves fixedly connected to the outer surface of the pump body, and a water conveying pipe fixedly connected to one end of the two check valves. The extrusion device body is provided with a water tank and an atomizing nozzle on its exterior. The two water conveying pipes are fixedly connected to the water tank and the atomizing nozzle respectively. A piston is slidably installed inside the pump body. The two connecting rods are respectively connected and fixed to one of the cutting tools and the piston at one end.

[0009] A linkage structure is provided between the two cutting tools.

[0010] Furthermore, the two cutting tools are symmetrically arranged and located on the left and right sides of the extrusion tube. The extrusion device body is provided with a guide structure on the side near the extrusion tube to limit the movement of the two cutting tools.

[0011] Furthermore, a mounting platform is welded to the outer surface of the extrusion device body, the drive motor is fixed to the upper surface of the mounting platform, and the back of the drive disk is fixed to the output shaft of the drive motor.

[0012] Furthermore, the pump body and water tank are both fixed to the outer surface of the mounting platform, and the atomizing nozzle is fixed to the outer surface of the extrusion device body by clamps, with the nozzle on the atomizing nozzle facing the two blades.

[0013] Furthermore, the pump body is provided with a pump chamber, and the two check valves are symmetrically installed on the outer surface of the pump body. Both check valves are connected to the pump chamber, and valve plates are elastically hinged inside the two check valves. The two valve plates are opened and closed according to the reciprocating motion of the piston.

[0014] Furthermore, the linkage structure consists of a cover, a gear, and two racks. The two racks are symmetrically arranged and both mesh with the gear. The gear bearing is installed in the middle of the inside of the cover. Each of the two racks has a connecting shaft fixed at one end. The two connecting shafts are respectively fixed to the outer surfaces of the two cutters.

[0015] Furthermore, the cover is hollow inside and has through-holes at both ends, and a bracket for fixing the cover is fixed on the outer surface of the extrusion device body.

[0016] Compared with the prior art, the present invention provides an extrusion device for plastic pipe fittings, which has the following advantages:

[0017] 1. The extrusion device for this plastic pipe fitting uses a drive motor to drive the drive disc to rotate back and forth. By utilizing the rolling cooperation between the roller and the swing frame, the two cutters can move relative to each other or move apart. This design can efficiently shear materials. The linkage structure ensures that when one side of the cutter moves, the other side of the cutter can also move accordingly, enhancing the synchronicity and efficiency of the shearing action.

[0018] 2. This plastic pipe fitting uses an extrusion device, which changes the pressure inside the pump body by the displacement of the piston. In conjunction with the opening and closing of the check valve, it realizes the effective extraction and delivery of coolant. The coolant is sprayed out through the atomizing nozzle to directly cool the cutting tool, prevent overheating due to long-term operation, and extend the service life of the cutting tool.

[0024] 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.

[0025] Please see Figures 1 to 4An extrusion device for plastic pipe fittings includes an extrusion device body 1 and an extrusion tube 2 fixedly connected to the discharge end of the extrusion device body 1. The extrusion device body 1 has two cutters 3, a drive mechanism 5, and a water supply device 6 externally disposed. A linkage structure 8 is provided between the two cutters 3. The linkage structure 8 consists of a cover 801, a gear 802, and two racks 803. The two racks 803 are symmetrically arranged and both mesh with the gear 802. The gear 802 bearings are installed in the middle of the interior of the cover 801. A connecting shaft 804 is fixed to one end of each rack 803, and the two connecting shafts 804 are respectively fixed to the outer surface of the two cutters 3. The two cutters 3 achieve synchronous movement through the linkage structure 8. When the gear 802 in the linkage structure 8 rotates, the two racks 803 drive their respective connecting shafts 804 and cutters 3 to move in relative or opposite directions, thereby achieving precise shearing or cutting of the material. The cover 801 is equipped with a limiting structure that guides the two racks 803, so that the racks 803 can be stably transmitted.

[0026] It should be noted that the cover 801 is hollow inside and has through-holes at both ends. A bracket for fixing the cover 801 is fixed to the outer surface of the extrusion device body 1. The two cutters 3 are symmetrically arranged and located on the left and right sides of the extrusion tube 2. A guide structure 9 for limiting the two cutters 3 is provided on the side of the extrusion device body 1 near the extrusion tube 2. The extrusion device body 1 is a conventional technology known to the public in the prior art, so its specific structural composition and working principle will not be described in detail in this article.

[0027] In this embodiment, the drive mechanism 5 includes a drive motor 501, a drive disk 502, and a swing frame 504. The front of the drive disk 502 is equipped with a roller 503 that is rolled and connected to the inner side of the swing frame 504. The left and right sides of the swing frame 504 are fixed with connecting rods 505. The outer surface of the extrusion device body 1 is welded with a mounting platform 4. The drive motor 501 is fixed to the upper surface of the mounting platform 4. The back of the drive disk 502 is fixed to the output shaft of the drive motor 501. By starting the drive motor 501, the drive disk 502 is rotated half a turn in both directions, which drives the swing frame 504 to reciprocate.

[0028] In this embodiment, the water conveying device 6 includes a pump body 601, two check valves 602 fixedly connected to the outer surface of the pump body 601, and a water conveying pipe 604 fixedly connected to one end of the two check valves 602. The extrusion device body 1 is provided with a water tank 7 and an atomizing nozzle 10. The two water conveying pipes 604 are fixedly connected to the water tank 7 and the atomizing nozzle 10 respectively. A piston 603 is slidably installed inside the pump body 601. The two connecting rods 505 are respectively connected and fixed to one of the cutters 3 and the piston 603 at one end. The pump body 601 and the water tank 7 are both fixed to the outer surface of the mounting platform 4. The atomizing nozzle 10 is fixed to the outer surface of the extrusion device body 1 by a clamp, and the nozzle on the atomizing nozzle 10 faces the two cutters 3.

[0029] Specifically, the pump body 601 has a pump chamber inside, and two check valves 602 are symmetrically installed on the outer surface of the pump body 601. Both check valves 602 are connected to the pump chamber, and valve plates are elastically hinged inside each check valve 602. The valve plates open and close according to the reciprocating motion of the piston 603. Coolant is delivered to the atomizing nozzle 10 through the water supply pipe 803 and sprayed onto the cutter 3 in an atomized form. This precise cooling method ensures that the cutter 3 maintains a suitable temperature during operation, preventing overheating damage and improving cutting efficiency.

[0030] The working principle of the above embodiments is as follows:

[0031] In use, the controller starts the drive mechanism 5, and the drive motor 501 drives the drive disc 502 to rotate back and forth. Through the rolling cooperation of the roller 503 and the swing frame 504, the two connecting rods 505 drive the left blade 3 and the piston 603 respectively. During the movement of the left blade 3, the linkage structure 8 drives the other blade 3 to move, so that the two blades 3 move relative to each other or separate, thereby achieving the shearing of materials. When the piston 603 moves, it continuously changes the pressure in the pump body 601. With the opening and closing of the two check valves 602, the coolant in the water tank 7 is drawn and transported through the water pipe 604, and finally sprayed out through the atomizing nozzle 10 to cool down the blade 3.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
