Detailed Implementation

[0050] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0051] like Figures 1 to 7 As shown, the present invention provides an extrusion molding apparatus for processing plastic particles, comprising:

[0052] Main support frame 1, independently fixed;

[0053] Feeding mechanism 2, mounted on main support 1, is used to transport raw materials for plastic particle preparation;

[0054] The extrusion mechanism 3 is mounted on the main support 1 and is connected to the feeding mechanism 2. It is used to extrude raw materials to form plastic granules.

[0055] The extrusion mechanism 3 also includes:

[0056] The extrusion cylinder 31 has an extrusion chamber inside and is connected to the feeding mechanism 2;

[0057] The first feed plate 32 is installed inside the extrusion cylinder 31, and the first feed plate 32 has a number of arc-shaped through holes of the same specification arranged in a circumferential array.

[0058] Two second filter plates 33 are installed inside the extrusion cylinder 31. Several arc-shaped through holes of different specifications are arranged on the circumference of the second filter plates 33.

[0059] A forming plate 34 is installed inside the extrusion cylinder 31, and a number of forming holes are provided on the forming plate 34;

[0060] The rotating shaft 35 is rotatably disposed inside the extrusion cylinder 31;

[0061] The feeding plate 36 is fixedly mounted on the rotating shaft 35. The feeding plate 36 rotates inside the extrusion cylinder 31 and is in contact with the end face of the first feed plate 32. The feeding plate 36 is provided with two feeding blocks, each of which is provided with an inclined guide surface facing the rotation direction of the feeding plate 36.

[0062] Three guide plates 37 are all fixedly mounted on the rotating shaft 35, and the guide plates 37 rotate inside the extrusion cylinder 31; the guide plates 37 are provided with two push blocks, and each push block is provided with two inclined guide surfaces.

[0063] The rotary cutting plate 38 is fixedly mounted on the rotating shaft 35. The rotary cutting plate 38 is rotatably set at the output end of the extrusion cylinder 31 and is in contact with the outer end face of the forming plate 34. The contact end is provided with a blade. The arrangement inside the extrusion mechanism 3, from the inside to the outside, is as follows: feeding plate 36, first feeding plate 32, guide plate 37, second filter plate 33, guide plate 37, second filter plate 33, guide plate 37, forming plate 34, rotary cutting plate 38.

[0064] The working process and principle of the device are as follows: After the raw material enters the extrusion cylinder 31, it first encounters the feeding plate 36. The feeding plate 36 rotates with the rotating shaft 35, and the feeding blocks on it push the raw material through the inclined guide surface. The feeding plate 36 is in contact with the end face of the first feed plate 32. The raw material passes through several arc-shaped through holes of the same specification in a circumferential array on the first feed plate 32 for preliminary filtration, removing some larger impurities or incompletely melted particles. After preliminary filtration, the raw material continues to flow forward and encounters two second filter plates 33. These two second filter plates 33 are respectively provided with arc-shaped through holes of different specifications. Through the through holes of different sizes, the raw material is further refined, removing finer impurities and making the raw material more uniform. After passing through the second filter plates 33, the raw material is guided by the guide plate 37. The guide plate 37 rotates with the rotating shaft 35, and the pusher blocks on it push the raw material through the inclined guide surface. The raw material is extruded outwards; after multiple filtrations and mixing, the raw material finally reaches the forming plate 34. The raw material is extruded into plastic granules of a specific shape and size through several forming holes on the forming plate 34; the rotary cutting plate 38 rotates with the rotating shaft 35, and its blades fit against the outer end face of the forming plate 34 to cut the extruded plastic granules into the required length; the cut plastic granules are discharged through the output end of the extrusion cylinder 31, completing the entire extrusion molding process; the multi-stage filtration system effectively removes impurities from the raw material, improving the purity of the product; the use of rotating components to mix the material ensures the uniformity of the material in the molten state, thereby improving the molding quality; the forming plate 34 can precisely control the shape and size of the plastic particles, and the rotary cutting plate 38 ensures efficient and precise cutting operations, reducing material waste while also ensuring the appearance quality of the product.

[0065] The extrusion mechanism 3 also includes:

[0066] A protective net 39 is fixedly installed on the extrusion cylinder 31 and covers the output end of the extrusion mechanism 3. The function of the protective net 39 is to prevent abnormal situations that may occur during the extrusion process, such as plastic particles breaking, splashing, or sticking together for various reasons, thereby avoiding injury to the equipment or operators. During the extrusion process, due to the high temperature of the raw material and the operation of the equipment, operators need to maintain a certain safe distance. The protective net 39 not only provides an additional safety barrier for operators, but also reduces the potential risks caused by improper operation or equipment failure, thereby improving the safety of use.

[0067] like Figures 6 to 7 As shown, the extrusion mechanism 3 also includes:

[0068] The hinge seat 3a is fixedly installed on the extrusion cylinder 31;

[0069] Hinged frame 3b is hinged to hinge seat 3a;

[0070] The cover plate 3c is fixedly connected to the hinge frame 3b and is oscillatingly mounted on the extrusion cylinder 31;

[0071] Two locking components are symmetrically arranged at both ends of the extrusion cylinder 31 to lock the cover plate 3c;

[0072] When the extrusion mechanism 3 is not under maintenance or has its parts replaced, the cover plate 3c is pivotally mounted on the extrusion cylinder 31 via the hinged connection between the hinge frame 3b and the hinge seat 3a, and is symmetrically locked by two locking components to ensure the sealing and safety of the extrusion chamber. When maintenance or replacement of parts is required, the operator first unlocks the two locking components, so that the cover plate 3c is no longer fixed; then the cover plate 3c is pivotally opened from the extrusion cylinder 31, exposing the inside of the extrusion chamber; after the cover plate 3c is opened, the operator performs the necessary maintenance or replacement work inside the extrusion chamber; after the maintenance or replacement work is completed, the operator pivots the cover plate 3c back to its original position and symmetrically locks it by the two locking components; this improves the safety and reliability of the extrusion mechanism 3 and also facilitates the maintenance and replacement work of the operator.

[0073] like Figure 7 As shown, the locking assembly includes:

[0074] Lock plate 3d is fixedly installed on extrusion cylinder 31;

[0075] Lock hook seat 3e is fixedly installed on lock plate 3d;

[0076] The locking hook 3f is oscillatingly mounted on the locking hook seat 3e. The locking hook 3f is set in a "U" shape to lock the cover plate 3c.

[0077] The locking screw 3g is threaded and inserted into the locking hook 3f to fix the locking hook 3f.

[0078] The working process and principle of the locking assembly are as follows: When it is necessary to lock the cover plate 3c, the operator first ensures that the cover plate 3c is correctly closed and adheres to the extrusion cylinder 31; then, the operator swings the locking hook 3f so that its "U"-shaped opening is aligned with and hooks the edge of the cover plate 3c; once the locking hook 3f hooks the cover plate 3c, the operator can rotate the locking screw 3g to insert its thread and fix it in the corresponding position of the locking hook 3f; the tightening of the locking screw 3g will generate sufficient pressure to firmly fix the locking hook 3f to the locking hook seat 3e, thereby... Ensure that the cover plate 3c is tightly locked. When it is necessary to open the cover plate 3c for maintenance or cleaning, the operator first rotates the locking screw 3g counterclockwise to unscrew and loosen it from the locking hook 3f. Then, the operator can swing the locking hook 3f to disengage it from the edge of the cover plate 3c. Once the locking hook 3f is released, the cover plate 3c can be opened. The locking assembly not only ensures that the cover plate 3c is firmly locked during the operation of the extrusion mechanism 3, but also provides a convenient unlocking operation, which not only ensures the safety of the extrusion process, but also facilitates the maintenance and cleaning work of the operator.

[0079] like Figure 7 As shown, a lifting tab 3h is provided on the cover plate 3c; the lifting tab 3h provides an easy-to-grip force application point, making it easier for the operator to apply force to open or close the cover plate 3c, reducing the difficulty of operation and physical exertion.

[0080] like Figures 1 to 2 As shown, the feeding mechanism 2 includes:

[0081] The feeding cylinder 21 is fixedly installed on the main support 1;

[0082] The drive shaft 22 is rotatably disposed inside the feeding cylinder 21;

[0083] Multiple impellers 23 are arranged and mounted on a drive shaft 22, and are driven to rotate by the drive shaft 22.

[0084] The feed hopper 24 is connected to the feeding cylinder 21;

[0085] Motor 25 is fixedly mounted on the main support 1 and is used to drive drive shaft 22 to rotate;

[0086] The working process and principle of the feeding mechanism 2 are as follows: the raw material for preparing plastic particles is fed into the feeding cylinder 21 through the feeding hopper 24; the motor 25 starts and drives the drive shaft 22 to rotate inside the feeding cylinder 21; multiple impellers 23 are arranged and mounted on the drive shaft 22 and rotate with the rotation of the drive shaft; the impellers 23 can effectively stir the raw material in the feeding cylinder 21 to avoid the accumulation or blockage of the raw material during the feeding process; the rotation of the impellers also generates a certain conveying force, which conveys the raw material from one end of the feeding cylinder 21 to the other end, that is, towards the extrusion mechanism 3; after being stirred and conveyed by the impellers 23, the raw material is evenly conveyed to the extrusion mechanism 3 connected to the feeding cylinder 21; the impellers 23 can continuously stir and convey the raw material, thereby continuously and stably supplying the raw material to the extrusion mechanism 3, ensuring the continuity and stability of the extrusion molding process.

[0087] like Figure 6 As shown, several strips 26 are arranged circumferentially on the inner wall of the feeding cylinder 21, and a material passage is provided between two adjacent strips 26. After the raw material enters the feeding cylinder 21, due to the circumferential arrangement of the strips 26, the raw material is dispersed in the material passage between adjacent strips 26. Due to the presence of the strips 26 and the material passage, the raw material is effectively dispersed and stirred during the conveying process, avoiding local accumulation or blockage, and ensuring that each area has enough material for the impeller 23 to push. The strips 26 and the material passage can also reduce the backflow of material. When the impeller 23 rotates, some material may try to flow against the current, but the strips 26 block this situation, forcing the material to move only in the correct direction.

[0088] like Figure 6 As shown, a gap is provided between the outer diameter of the impeller 23 and the inner diameter of the circumference formed by the various sets of strips 26. The gap ensures that the impeller 23 rotates smoothly. The gap ensures that the impeller will not experience excessive resistance during rotation, thereby avoiding increased energy consumption and equipment wear. The existence of the gap avoids direct contact between the impeller 23 and the strips 26 during rotation, thereby preventing heat and wear caused by friction or collision. This helps to extend the service life of the equipment and reduce maintenance costs. The rotation of the impeller 23 and the setting of the gap work together to make the raw material more evenly distributed in the feeding cylinder 21. This is beneficial to the subsequent extrusion molding process, improving the quality and stability of the product.

[0089] The extrusion molding device for processing plastic particles according to this utility model has common mechanical methods in terms of installation, connection or setting. Any method that can achieve its beneficial effect can be implemented.

[0090] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
