Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to an engineering plastic granulation and stranding device. Background Technology

[0002] In the plastics processing industry, engineering plastic granulation is a crucial step. In this process, plastic raw materials undergo melting and extrusion to form continuous plastic strips. These strips then need to be cooled and crushed to ultimately obtain granular plastic products. To ensure that the plastic strips are stably and accurately fed into the subsequent cooling and crushing equipment, specialized strip-carrying equipment is required.

[0003] Existing engineering plastic granulation and strip forming equipment typically employs a design with two conveying rollers, one above the other. These rollers have multiple arc-shaped slots for placing and fixing the plastic strips to prevent them from shifting during transport. While this design improves the stability of the plastic strip transport to some extent, it also reveals some significant limitations. Because the size and shape of the arc-shaped slots are fixed, they are difficult to accommodate plastic strips of different thicknesses. In actual production, the size of the plastic strips may vary due to factors such as raw materials and extrusion processes. This means that the fixed slots cannot effectively limit the size of plastic strips of all sizes. When the size of the plastic strip does not match the slot, it is easy for it to shift during transport, affecting production efficiency and product quality. Utility Model Content

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides an engineering plastic granulation and stranding device. The engineering plastic granulation and stranding device includes a main component 100, including a support platform 101, a support shell 102, a guide shell 103, a conveying roller 104, a drive shaft 105, and a drive motor 106. The support shell 102 is fixed to the top of the support platform 101, the guide shell 103 is fixed to one side of the support shell 102, the conveying roller 104 is fixed to the surface of the drive shaft 105, the drive shaft 105 is rotatably connected inside the support shell 102, and the drive motor 106 is fixed to one side of the support platform 101.

[0031] The support platform 101 is used to support the support shell 102, the guide shell 103 is used to guide the plastic strip coming out of the cooling pool so that the water on the surface of the plastic strip can slide back into the cooling pool, the conveying roller 104 is used to convey the plastic strip, and the drive motor 106 is used to drive the drive shaft 105 to rotate, thereby driving the conveying roller 104 to rotate. The working principle of the drive motor 106 is prior art, and those skilled in the art should know it clearly.

[0032] The extrusion assembly 200 is disposed within the support housing 102 and includes a limiting disk 201a disposed above the conveying roller 104. A rotating shaft 201b is rotatably connected to the limiting disk 201a via threads. A support disk 201c is fixed to the surface of the rotating shaft 201b. A friction ring 201d is fixed to the surface of the support disk 201c. Threads with opposite directions of rotation are respectively provided at both ends of the rotating shaft 201b. The two limiting disks 201a are respectively rotatably connected to the two threaded surfaces of the rotating shaft 201b via threads.

[0033] Limiting discs 201a are provided on both sides of the support disc 201c. The two support discs 201c limit the two sides of the top of the plastic strip, so that the plastic strip can be stably stopped below the friction ring 201d. The support discs 201c apply a downward pressure to the friction ring 201d, so that there is a large friction between the friction ring 201d and the plastic strip, which makes the plastic strip squeezed on the surface of the conveyor roller 104. As the conveyor roller 104 moves the plastic strip, it can drive the support disc 201c to rotate.

[0034] By setting opposite threads on the rotating shaft 201b, the two limiting discs 201a can move away from or closer to each other when rotating in the same direction, thereby adjusting the distance between the limiting discs 201a and the plastic strip, so that the two limiting discs 201a can match plastic strips of different thicknesses.

[0035] Specifically, the extrusion assembly 200 also includes a positioning element 202 disposed on the surface of the rotating shaft 201b, including a support 202a disposed on the surface of the rotating shaft 201b, the support 202a being fixed to the surface of the rotating shaft 201b by fixing bolts 202b.

[0036] There are three fixing bolts 202b on the support 202a, which are used to fix the support 202a so that the support 202a will not move relative to the rotating shaft 201b.

[0037] Specifically, a support column 202c is fixed on one side of the support base 202a, and a positioning disk 202d slides on the surface of the support column 202c.

[0038] There are three support columns 202c on one side of the support base 202a, which are used to support the positioning disk 202d so that the positioning disk 202d can slide stably on the surface of the support column 202c.

[0039] Specifically, a first spring 202e is sleeved on the surface of the support column 202c, a positioning column 202f is fixed on one side of the positioning disk 202d, and a positioning hole 201a-1 is opened on one side of the limiting disk 201a, with the positioning column 202f inserted into the positioning hole 201a-1.

[0040] There are two positioning pins 202f fixed on one side of the positioning plate 202d. By inserting the two positioning pins 202f into the positioning hole 201a-1, the relative angle between the limiting plate 201a and the positioning plate 202d can be fixed, thereby fixing the relative angle between the limiting plate 201a and the rotating shaft 201b, and thus positioning the two limiting plates 201a on the rotating shaft 201b.

[0041] Example 2

[0042] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0043] Specifically, the extrusion assembly 200 also includes a lifting component 203, which is disposed inside the support shell 102. It includes an adjusting bolt 203a that is rotatably connected to the support shell 102 by a thread. A rotating sleeve 203b is rotatably connected to the surface of the adjusting bolt 203a. A lifting plate 203c is fixed to the bottom of the rotating sleeve 203b.

[0044] The adjusting bolt 203a and the rotating sleeve 203b are rotatably connected by a bearing. When the adjusting bolt 203a is rotated, it can move up and down relative to the support shell 102, thereby causing the adjusting bolt 203a to drive the lifting plate 203c to move up and down through the rotating sleeve 203b.

[0045] Specifically, a lifting rod 203d slides inside the lifting plate 203c, and a pressure plate 203e is fixed to the bottom of the lifting rod 203d.

[0046] The lifting rod 203d slides inside the support shell 102 to limit the movement of the pressure plate 203e, so that the pressure plate 203e can move up and down stably.

[0047] Specifically, a second spring 203f is fixed to the top of the pressure plate 203e, the other end of the second spring 203f is fixed to the bottom of the lifting plate 203c, and a support block 203g is fixed to the bottom of the pressure plate 203e.

[0048] The second spring 203f is in a compressed state and is used to push the pressure plate 203e, so that the pressure plate 203e has a downward pressure. There are multiple support blocks 203g fixed at the bottom of the pressure plate 203e.

[0049] Specifically, a support rod 203h slides inside the support block 203g, and a third spring 203i is fixed to the top of the support rod 203h. The other end of the third spring 203i is fixed to the inner top wall of the support block 203g.

[0050] The third spring 203i is in a compressed state and is used to push the support rod 203h, so that the support rod 203h has a downward compressive force.

[0051] Specifically, a connecting shaft 203j is slidably connected inside the support rod 203h, and the end of the connecting shaft 203j is inserted into the rotating shaft 201b.

[0052] The portion of the connecting shaft 203j located inside the support rod 203h is a rhomboid column, preventing relative rotation between the connecting shaft 203j and the support rod 203h. The connecting shaft 203j inserted into the rotating shaft 201b is cylindrical, allowing the rotating shaft 201b to rotate stably on the surface of the connecting shaft 203j. This enables the limiting disk 201a and the support disk 201c to rotate stably relative to the support rod 203h, thus ensuring stable conveying of the plastic strip.

[0053] Specifically, a limit cap 203k is fixed to the other end of the connecting shaft 203j, and a fourth spring 203l is fixed to the inner wall of the limit cap 203k. The fourth spring 203l is fixed to the inner wall of the support rod 203h.

[0054] The fourth spring 203l is in a stretched state and is used to pull the limit cap 203k, so that the limit cap 203k pushes the connecting shaft 203j, thereby making the connecting shaft 203j stably inserted into the support rod 203h.

[0055] In use, when conveying plastic strips of different thicknesses, the adjusting bolt 203a can be rotated, causing the adjusting bolt 203a to move the lifting plate 203c upward. This causes the lifting plate 203c to pull the pressure plate 203e upward via the second spring 203f, which in turn moves the pressure plate 203e upward. This pressure plate 203e then moves the support block 203g upward, causing the support block 203g to pull the support rod 203h upward via the third spring 203i. The support rod 203h then moves the rotating shaft 201b upward, thus moving the friction ring 201d away from the plastic strip. At this point, the two fixed points on both sides of the support plate 201c can be adjusted. Pulling the positioning plate 202d to both sides releases the positioning pin 202f from limiting the positioning plate 201a. At this time, both positioning plates 201a can be rotated simultaneously, bringing them closer together to accommodate thinner plastic strips. Rotating the positioning plates 201a in the opposite direction moves them further apart to accommodate thicker plastic strips. Once the positioning plate 201a is adjusted to the correct position, release the positioning plate 202d. Under the restoring force of the first spring 202e, the positioning pin 202f can be re-inserted into the positioning hole 201a-1, thus limiting the positioning plate 201a again, thereby completing the adjustment of the positioning plate 201a.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
