Description

Technical Field

[0001] This utility model relates to the field of granulation equipment technology, specifically to a granulation equipment for nylon chips. Background Technology

[0002] Nylon chip granulation is a process in which nylon waste or raw materials are washed, crushed, and dried, then melted and plasticized through an extruder, cooled and shaped, and cut into standard granules. The final product can be used in spinning, engineering plastics, or modified materials.

[0003] Chinese patent discloses a granulation device for nylon 6 chips (publication number: CN221872720U). This device has several lubrication chambers inside the base, and graphite grooves inside the lubrication chambers, allowing graphite to enter the nylon 6 surface through through holes for lubrication. This facilitates maintaining the same diameter of the nylon 6 as the inner wall diameter of the inner cylinder and enables stable feeding, thus facilitating cutting accuracy during granulation. However, this structure still has the following drawbacks:

[0004] In the aforementioned device, nylon is conveyed and guided through an inner cylinder, and the graphite inside the inner cylinder does indeed lubricate the nylon surface. However, after prolonged friction between the nylon and graphite, the graphite end face may become worn, thus failing to contact the nylon and provide lubrication. The inner cylinder requires frequent shutdowns and replacement of the graphite lubricating material, which is detrimental to production efficiency. Therefore, a granulation device for nylon chips is proposed to solve the above problems. Utility Model Content

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A granulation apparatus for nylon chips includes a granulator, wherein the lower end of the granulator is provided with a plurality of guiding mechanisms;

[0007] The guiding mechanism includes a conical cylinder, with a plurality of push plates fixedly connected to the inner side of the conical cylinder. Each push plate is arranged equidistantly around the central axis of the conical cylinder. A connecting rope is fixedly connected to the lower end of the end face of the conical cylinder, and a counterweight is fixedly connected to the bottom end of the connecting rope. The diameter of the conical cylinder gradually increases towards the direction of the connecting rope, and the spacing between the push plates at relative positions gradually increases towards the direction of the connecting rope.

[0008] As a further embodiment of this utility model: a guide copper tube is inserted into the inner wall of the conical cylinder, and a push groove is opened on the guide copper tube near each push plate. The push groove extends in the length direction of the guide copper tube, and the inner wall of each push groove is slidably connected to the push plate. A graphite column receiving hole is opened on the surface of the guide copper tube at the end of each push groove.

[0009] As a further embodiment of this utility model: a flange is fixedly installed at the end of the guide copper tube away from the push groove, a clamping tube is inserted into and slidably connected to the inner wall of the guide copper tube, and an end plate is fixedly connected at the end of the clamping tube away from the push groove. The surface of the end plate abuts against the flange and is fixedly connected by screws.

[0010] As a further embodiment of this utility model: the inner diameter of the guide copper tube located inside the push groove is consistent with the overall inner diameter of the clamping tube, and the end of the clamping tube located away from the end plate abuts against the inner wall of the guide copper tube near the graphite column receiving hole.

[0011] As a further embodiment of this utility model: the granulator includes a support, and a plurality of mounting holes are provided at the lower end of the outer wall of the support. Each mounting hole is equidistant along the length direction of the support. The inner side of each mounting hole is slidably connected to the outer wall of the conical cylinder. A pulley is rotatably connected to the middle of the inner wall of each mounting hole. A connecting rope is clamped and slidably connected to the outer side of the pulley. The lower end of the inner wall of the support is connected to the connecting rope through it.

[0012] As a further embodiment of this utility model: the surface of the support abuts against each flange, and the surface of the flange is threadedly connected to the surface of the support by screws.

[0013] As a further embodiment of this utility model: a servo motor is fixedly installed at the top center of the support, a cutting blade is fixedly connected to the output shaft of the servo motor, and mounting ears are symmetrically fixedly installed at the lower end of the side wall of the support.

[0014] The beneficial effects of this utility model are:

[0015] (1) In this utility model, the nylon is conveyed and guided by the guide copper tube in the mounting hole of the support. Graphite column receiving holes are opened at equal intervals on the surface of the guide copper tube. After the graphite lubricating column is inserted into the graphite column receiving hole, it can contact the end of the graphite column receiving hole to lubricate the nylon passing through the guide copper tube. The graphite lubricating column can be freely inserted and removed in the graphite column receiving hole, which is convenient for replacement. The guide copper tube can be used with a clamping tube to clamp and position the graphite lubricating column.

[0016] (2) A tapered cylinder is installed on the outside of the guide copper tube. Multiple pushers that contact the graphite lubrication column are installed on the inner wall of the tapered cylinder. When the graphite lubrication column is worn due to friction with the nylon, the tapered cylinder automatically moves along the length of the guide copper tube and pushes the graphite lubrication column toward the inner wall of the guide copper tube with the help of the pushers. This ensures that the graphite lubrication column can contact and lubricate the nylon surface for a long time, and avoids the nylon from not contacting the graphite lubrication column due to local wear.

Detailed Implementation

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-5 As shown, a granulation device for nylon chips includes a granulator 1, with several guide mechanisms 2 at its lower end. Each guide mechanism 2 includes a conical cylinder 201, with several pushers 202 fixedly connected to its inner side. The pushers 202 are equidistantly arranged around the central axis of the conical cylinder 201. A connecting rope 203 is fixedly connected to the lower end of the end face of the conical cylinder 201, and a counterweight 204 is fixedly connected to the bottom end of the connecting rope 203. The diameter of the conical cylinder 201 gradually increases towards the connecting rope 203, and the spacing between the relatively positioned pushers 202 gradually increases towards the connecting rope 203. Figure 2-Figure 3 As shown, when the conical cylinder 201 moves to the right, the distance between the pusher plate 202 and the guide copper tube 205 gradually decreases, and the pusher plate 202 can be inserted into the push groove 207. When the counterweight block 204 falls, it drives the conical cylinder 201 to move to the right through the connecting rope 203.

[0026] A guide copper tube 205 is inserted into the inner wall of the conical cylinder 201. Each guide copper tube 205 has a push groove 207 near each pusher plate 202, extending along the length of the guide copper tube 205. The inner wall of each push groove 207 is slidably connected to the pusher plate 202. A graphite column receiving hole 206 is formed at the end of each push groove 207 on the surface of the guide copper tube 205. Figure 3 , Figure 5 As shown, the graphite column receiving hole 206 is inserted into the graphite column, and the inner end face of the graphite column extends into the guide copper tube 205 for easy contact with nylon and lubrication.

[0027] A flange 208 is fixedly installed at the end of the guide copper tube 205 away from the push groove 207. A clamping tube 209 is inserted into and slidably connected to the inner wall of the guide copper tube 205. An end plate 210 is fixedly connected to the end of the clamping tube 209 away from the push groove 207. The surface of the end plate 210 abuts against the flange 208 and is fixedly connected by screws. Figure 5 As shown, the guide copper tube 205 is placed vertically outside the support 101, and the graphite column is inserted horizontally into the graphite column receiving hole 206. At this time, the graphite column is not easily dropped into the guide copper tube 205 due to gravity. When the clamping tube 209 moves along the inside of the guide copper tube 205, the end of the clamping tube 209 can abut against the inserted graphite column and, in conjunction with the graphite column receiving hole 206, clamp and position the graphite column, thus... Figure 3 , Figure 5 As shown, when the guide copper tube 205 is placed horizontally, the graphite column will not fall into the guide copper tube 205 due to gravity because it is held by the end of the clamping tube 209. After the guide copper tube 205 is connected and fixed to the support 101, the screw lock between the clamping tube 209 and the guide copper tube 205 is released.

[0028] The inner diameter of the guide copper tube 205 located inside the push groove 207 is the same as the overall inner diameter of the clamping tube 209, and the end of the clamping tube 209 located away from the end plate 210 abuts against the inner wall of the guide copper tube 205 near the graphite column receiving hole 206. Figure 5 As shown, the insertion of the clamping tube 209 inside the guide copper tube 205 does not interfere with the delivery of nylon.

[0029] The granulator 1 includes a support 101. Several mounting holes 103 are formed at the lower end of the outer wall of the support 101. These mounting holes 103 are equidistant along the length of the support 101. The inner side of each mounting hole 103 is slidably connected to the outer wall of a conical cylinder 201. A pulley 106 is rotatably connected to the center of the inner wall of each mounting hole 103. A connecting rope 203 is clamped and slidably connected to the outer side of the pulley 106. The lower end of the inner wall of the support 101 is connected to the connecting rope 203. The surface of the support 101 abuts against each flange 208. The surfaces of the flanges 208 are threadedly connected to the surface of the support 101 with screws. A servo motor 104 is fixedly mounted at the top center of the support 101. A cutting blade 105 is fixedly connected to the output shaft of the servo motor 104. Mounting ears 102 are symmetrically fixedly mounted at the lower end of the side walls of the support 101. Figure 1 As shown, servo motor 104 can be an HG-KR model servo motor.

[0030] The working principle of this utility model:

[0031] When the device is in use, the support 101 is placed on the roller path of the nylon conveyor, and the mounting ear 102 is locked with the lower support plane by the bolt. The nylon is pushed into the guide copper tube 205 by the external conveying roller. The graphite lubricating column inserted in the graphite column receiving hole 206 can lubricate the surface of the nylon. Then the nylon is moved along the guide copper tube to the bottom of the cutting blade 105. When the servo motor 104 is started, the cutting blade 105 rotates and cuts and granulates the nylon below.

[0032] When a gap forms between the inner end of the graphite lubricating column and the nylon due to frictional wear, such as Figure 2 As shown, the counterweight 204 falls under the action of gravity, and the conical cylinder 201 is pulled to the right by the connecting rope 203. The push plate 202 on the inner wall of the conical cylinder 201 squeezes the outer end of the graphite lubricating column and moves the entire end of the graphite lubricating column toward the inside of the guide copper tube 205. Then the inner end of the graphite lubricating column continues to press against the nylon surface, which can provide a lubricating effect on the nylon surface for a long time.

[0033] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
