Description

Technical Field

[0001] This utility model relates to the field of plastic processing, and in particular to a plastic pelletizing machine. Background Art

[0002] The plastic products we use in daily life are basically made of plastic granules. In the processing of plastic granules, plastic raw materials and color powder need to be mixed, and then the mixed raw materials are melted and extruded using a pelletizer, and the plastic strips are pulled out and cut.

[0003] In existing plastic pelletizing machines, the hot-melted plastic strips are evenly extruded through multiple extrusion nozzles and fall into a water tank. However, there is a certain distance between the extrusion nozzles and the slitting blades. The initially extruded plastic strips need to be pulled out of the water tank and placed on multiple rollers by the operator using a lever or scissors until the end of the plastic strip is pulled out to the position of the slitting blades. However, it is troublesome and time-consuming for the operator to manually insert the lever or other tools completely into the back of the plastic strip, and it is also easy to make mistakes. In addition, the high temperature of the plastic strip can easily burn the operator, making the overall pulling operation troublesome and time-consuming. Furthermore, it is not convenient to store the lever or other tools afterwards.

[0004] Therefore, it is necessary to provide a new plastic pelletizing machine to solve the above-mentioned technical problems. Utility Model Content

[0009] Preferably, a locking rod is slidably connected inside the upper tube, and sliding openings are provided on both ends of the upper tube. The two ends of the locking rod are slidably connected to the sliding openings on both ends of the upper tube. A spring is sleeved on the locking rod, and a lifting cap is fixedly connected to the top end of the locking rod.

[0010] Preferably, a protruding ring is provided at one end of the clamp rod, and the protruding ring is located inside the upper tube.

[0013] Compared with related technologies, the plastic pelletizing machine provided by this utility model has the following beneficial effects:

[0014] 1. This utility model allows one end of the pull rod to slide out of the top cap by pulling it, while the locking part slides out of the positioning frame. Pulling the horizontal bar moves the pull rod, which pulls out the evenly extruded plastic strip evenly, so that it can enter the cooling pool and then enter the cutting machine for further slitting.

[0015] 2. This utility model allows the locking mechanism to be released by pulling the lifting cap, which causes the locking rod to slide relative to the upper position. The convex ring at one end of the locking rod moves accordingly, causing the spring to undergo elastic deformation. The lower end of the locking device slides out of the positioning hole on the locking device, thus releasing the locking device and facilitating the subsequent removal of the pull rod to safely and quickly pull out the plastic strip.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to Figures 1 to 3 A plastic pelletizing machine includes: a base 1, a processing chamber 2 fixedly connected to the base 1, a feeding hopper 21 provided on the upper cavity wall of the processing chamber 2, an extrusion chamber 3 provided at the middle position of the base 1, a conveying pipe 31 installed and connected between the processing chamber 2 and the extrusion chamber 3, a cooling pool 4 fixedly connected to the front end of the base 1, and multiple extrusion ports provided on the side cavity wall of the extrusion chamber 3; a quick pull-out mechanism, including a pull-out rod 5, the pull-out rod 5 being located in front of the extrusion port, a top cap 51 provided at one end of the extrusion port, a positioning frame 52 provided at the other end of the extrusion port, a locking component 53 fixedly connected to one end of the pull-out rod 5, a locking assembly provided on the positioning frame 52, and a horizontal handle 54 fixedly connected to the locking component 53.

[0022] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the top cap 51 is provided with an insertion port, one end of the pull-out rod 5 is located in the insertion port, and an inclined plate 55 is fixedly connected to the extrusion port.

[0023] It should be noted that: pulling the pull-out rod 5 causes one end to slide out of the top cap 51, and at the same time causes the locking piece 53 to slide out of the positioning frame 52. Pulling the horizontal handle 54 causes it to move the pull-out rod 5, so that the evenly extruded plastic strip can be evenly pulled out to facilitate cooling in the cooling pool 4.

[0024] The inclined plate 55 is used to make the plastic strip automatically hang down to the front of the pull-out rod 5.

[0025] refer to Figure 2 and Figure 3 As shown, the locking component 53 is provided with a positioning port, and the locking assembly includes a right-angle plate 6, which is fixedly connected to the locking component 53. An upper tube 61 is fixedly connected to the right-angle plate 6.

[0026] refer to Figure 2 and Figure 3 As shown, a locking rod 7 is slidably connected inside the upper tube 61. Sliding openings are provided on both ends of the upper tube 61. The two ends of the locking rod 7 are slidably connected to the sliding openings on both ends of the upper tube 61. A spring 71 is sleeved on the locking rod 7. A lifting cap 72 is fixedly connected to the top of the locking rod 7.

[0027] It should be noted that: pulling the lifting cap 72 causes the locking rod 7 to slide relative to the upper tube 61, and the convex ring 8 at one end of the locking rod 7 moves accordingly, causing the spring 71 to undergo elastic deformation. The lower end of the locking rod 7 slides out of the positioning hole on the locking part 53, thereby releasing the locking part 53 and facilitating the subsequent removal of the pull-out rod 5.

[0028] refer to Figure 3 As shown, a protruding ring 8 is provided at one end of the lever 7, and the protruding ring 8 is located inside the upper tube 61.

[0029] It should be noted that the movement distance of the lever 7 is limited by the convex ring 8.

[0030] refer to Figure 3 As shown, one end of the spring 71 is connected to the convex ring 8, and the other end of the spring 71 is connected to the inner wall of the upper tube 61.

[0031] refer to Figure 1 As shown, an auxiliary roller 9 is provided at one end of the cooling pool 4, and a pressure strip 91 is fixedly connected to the inner wall of the cooling pool 4.

[0032] It should be noted that the uniformly extruded plastic strip is pulled out evenly into the cooling pool 4 for cooling, and the pressure strip 91 is used to limit the rubber strip to prevent it from bouncing.

[0033] The working principle of the plastic pelletizing machine provided by this utility model is as follows: When it is necessary to pull out the plastic strip, the lifting cap 72 is pulled to make the locking rod 7 slide relative to the upper tube 61. The convex ring 8 at one end of the locking rod 7 moves accordingly, causing the spring 71 to undergo elastic deformation. The lower end of the locking rod 7 slides away from the positioning hole on the locking part 53, thereby releasing the locking part 53 and facilitating the subsequent removal of the pull-out rod 5, so as to safely and quickly complete the pulling out of the plastic strip.

[0034] Pull the pull rod 5 so that one end slides out of the top cap 51, and at the same time, the locking piece 53 slides out of the positioning frame 52. Pull the horizontal handle 54 so that it drives the pull rod 5 to move, and pull out the end of the uniformly extruded plastic strip evenly so that it can be placed between multiple roller groups after entering the cooling pool 4, so that the end of the initially extruded plastic strip can enter the cutting machine for further slitting.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
