Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, specifically to a plastic pellet production system. Background Technology

[0002] The plastics production process typically includes key stages such as melting, molding, and cooling. Glass fiber, as a high-strength, lightweight reinforcing material, is made by stretching molten glass into long, thin fibers. Glass fiber possesses excellent mechanical properties (such as high strength and high modulus) and good chemical stability, enabling its widespread application in the manufacture of complex parts. Adding glass fiber to plastic granules can significantly improve the performance of composite materials, with specific advantages including:

[0003] 1. Enhanced mechanical properties: Significantly improves the strength, stiffness, and dimensional stability of plastics;

[0004] 2. Improve thermal and wear resistance: Enhance the heat resistance, wear resistance, and creep resistance of plastics;

[0005] 3. Optimize production efficiency: Due to the high strength and rigidity of glass fiber, it can effectively reduce the deformation and shrinkage of plastic during the molding process, thereby reducing the product defect rate and improving production efficiency.

[0006] In plastic granule production, glass fiber is primarily added during the plastic melting stage. Currently, the common method involves pre-winding glass fiber strips of varying proportions onto rollers, then using a traction device to pull the strips into the molten plastic for blending. The traction speed is adjusted according to the glass fiber addition ratio: a higher ratio requires a faster traction speed, and vice versa. However, when multiple types of glass fiber need to be added, existing technologies require multiple independent traction devices, which not only increases the complexity of the equipment structure but may also lead to cumbersome operation and increased costs. Therefore, simplifying the structure of the glass fiber addition device and improving its applicability and efficiency has become a pressing technical problem in plastic granule production. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a plastic granule production system that can add different proportions of glass fiber at the same time as needed, thereby greatly simplifying the structure of the glass fiber adding device and improving its applicability and efficiency.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a plastic pellet production system, comprising a plastic raw material feeding device, a melting device, a molding device, and a cooling device, wherein the melting device includes a melting furnace, characterized in that the melting device further includes:

[0009] There are multiple fixed shafts, which are fixed vertically to the ground at intervals.

[0010] A fiberglass winding bobbin, wherein each of the fixed bushings is provided with a freely rotatable fiberglass winding bobbin, the fiberglass winding bobbin being used for winding fiberglass tape; and

[0011] The wire drawing device, connected to the free ends of all the fiberglass tapes, can feed all the fiberglass tapes into the melting furnace at different speeds.

[0012] Furthermore, the wire drawing device includes a rotary power source, a rotary shaft, and multiple winding discs. The rotary power source is used to drive the rotary shaft to rotate. The multiple winding discs are spaced apart and sleeved on the rotary shaft. The diameter of the winding discs is adjustable. After the fiberglass strip coming out of the fiberglass winding cylinder is wound around the corresponding winding disc, it extends into the melting furnace.

[0013] Furthermore, the winding reel includes a fixed reel, support rods, support plates, a drive reel, and a drive source. The fixed reel is sleeved and fixed on the rotating shaft. The fixed reel has guide holes spaced circumferentially, connecting multiple sidewalls and one end of the fixed reel to the outside and extending radially. A slidable support rod is inserted into each guide hole. A support plate is provided at the end of each support rod. The drive reel is coaxially arranged with the fixed reel and rotatably mounted on the fixed reel. The drive reel has multiple arc-shaped grooves spaced circumferentially through the drive reel. Each arc-shaped groove corresponds to one of the guide holes. A toggle rod is fixed on each support rod and slidably inserted into the arc-shaped groove. The drive source is connected to the drive reel and is used to drive the drive reel to rotate. When the drive reel rotates clockwise, the toggle rod can drive the support rod to slide outward. When the drive reel rotates counterclockwise, the toggle rod can drive the support rod to slide inward.

[0014] Furthermore, the drive source includes a handle and a locking screw. The handle is disposed on the drive plate, and the locking screw is disposed on the drive plate. Rotating the locking screw will cause the locking screw to press against the fixed plate.

[0015] Furthermore, the support plate is an arc-shaped plate.

[0016] Furthermore, baffles are provided on the left and right sides of the support plate.

[0017] Furthermore, the plastic pellet production system also includes a guiding structure disposed between the glass fiber winding drum and the drawing device for guiding the glass fiber tape entering the winding drum.

[0018] Furthermore, the guide structure includes two central shafts and rollers arranged parallel to each other vertically. Multiple fixed rollers are spaced apart on the fixed shaft, and the rollers are arranged vertically and vertically at intervals. The fiberglass tape can slide through the two rollers and roll in connection with the rollers.

[0019] The beneficial effects of this utility model are:

[0020] The aforementioned plastic pellet production system includes a plastic raw material feeding device, a melting device, a molding device, and a cooling device. The melting device includes a melting furnace, a fixed shaft, a glass fiber winding drum, and a drawing device.

[0021] Specifically, there are multiple fixed shafts, which are vertically fixed to the ground at intervals. Each fixed shaft is fitted with a freely rotatable fiberglass winding drum, which is used to wind fiberglass tape. The drawing device is connected to the free ends of all the fiberglass tapes, enabling all the fiberglass tapes to be fed into the melting furnace at different speeds.

[0022] In use, first wind different fiberglass tapes onto the fiberglass winding spool, then connect the free end of the fiberglass tape to the drawing device, start the drawing device, and send the fiberglass tape into the melting furnace. The drawing device can simultaneously add different fiberglass tapes into the melting furnace at different speeds as needed for melting and shaping.

[0023] Using this plastic pellet production system can greatly reduce the investment in glass fiber addition equipment, saving costs and reducing the space occupied by the equipment, thereby improving production convenience and efficiency. Attached Figure Description

Detailed Implementation

[0031] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Please see Figures 1 to 3 This utility model provides a plastic pellet production system, including a plastic raw material feeding device, a melting device, a molding device, and a cooling device. The melting device includes a melting furnace 100, a fixed shaft 200, a glass fiber winding drum 300, and a wire drawing device 400.

[0033] Specifically, there are multiple fixed shafts 200, which are vertically fixed to the ground at intervals. Each fixed shaft 200 is fitted with a freely rotatable fiberglass winding drum 300, which is used to wind the fiberglass tape 1. The drawing device 400 is connected to the free ends of all the fiberglass tapes 1, and can feed all the fiberglass tapes 1 into the melting furnace 100 at different speeds.

[0034] In use, first, wind different fiberglass tapes 1 onto the fiberglass winding spool 300. Then, connect the free end of the fiberglass tape 1 to the drawing device 400, start the drawing device 400, and send the fiberglass tape 1 into the melting furnace 100. The drawing device 400 can simultaneously add different fiberglass tapes 1 into the melting furnace 100 at different speeds as needed for melting and shaping.

[0035] Using this plastic pellet production system can greatly reduce the investment in glass fiber addition equipment, saving costs and reducing the space occupied by the equipment, thereby improving production convenience.

[0036] Specifically, the winding reel 420 includes a fixed reel 421, support rods 422, support plates 423, a drive reel 424, and a drive source 425. The fixed reel 421 is sleeved and fixed on the rotating shaft 430. The fixed reel 421 has circumferentially spaced guide holes that connect multiple sidewalls and one end of the fixed reel 421 to the outside and extend radially. A slidable support rod 422 is inserted into each guide hole, and a support plate 423 is provided at the end of each support rod 422. The drive reel 424 is coaxially mounted with the fixed reel 421 and rotatably mounted on the fixed reel 421. The drive reel 424 has multiple circumferentially spaced arc-shaped grooves penetrating the drive reel 424. Each arc-shaped groove corresponds to one of the guide holes. Each support rod 422 is fixed with a lever 427, which is slidably inserted into an arc-shaped groove. The drive source 425 is connected to the drive disk 424 and is used to drive the drive disk 424 to rotate. When the drive disk 424 rotates clockwise, it can drive the support rod 422 to slide outward through the lever 427. When the drive disk 424 rotates counterclockwise, it can drive the support rod 422 to slide inward through the lever 427.

[0037] In this embodiment, the drive source 425 includes a handle 4251 and a locking screw 4252. The handle 4251 is disposed on the drive disk 424, and the locking screw 4252 is disposed on the drive disk 424. Rotating the locking screw 4252 will cause the locking screw 4252 to be tightened against the fixed disk 421. In practice, the locking screw 4252 can be loosened first, and then the drive disk 424 can be manually rotated by the handle 4251.

[0038] When using it, adjust the distance of the support plate 423 by adding the glass fiber tape 1 according to the required proportion. For example, when a higher proportion of glass fiber is required, the speed of glass fiber addition needs to be increased. This can be achieved by driving the drive disk 424 to rotate clockwise through the handle 4251, which drives the support rod 422 to move outward and moves the support plate 423 outward. Under the same rotation speed, the linear speed of the glass fiber can be increased, thus increasing the proportion of glass fiber added. The reverse is also true.

[0039] It should be noted that in other embodiments, the drive source 425 may also be other types of drive mechanisms, such as rotary motors, gear rack structures, etc.

[0040] As a preferred embodiment, in specific implementation, the support plate 423 can be set as an arc plate, and multiple circumferentially arranged arc plates can form a circle, which is convenient for winding the fiberglass tape 1. In addition, baffles 426 can be set on the left and right sides of the support plate 423 to prevent the fiberglass tape 1 from falling.

[0041] As another preferred embodiment, the system also includes a guide structure 500, which is disposed between the fiberglass winding drum 300 and the wire pulling device 400, for guiding the fiberglass tape 1 entering the winding reel 420.

[0042] Specifically, the guide structure 500 includes two central shafts 510 arranged vertically and parallel to each other and rollers 520. A plurality of fixed rollers 520 are spaced on the fixed shaft 200, and the rollers 520 are arranged vertically and perpendicularly. The fiberglass belt 1 can slide through the two rollers 520 and roll in connection with the rollers 520.

[0043] The roller 520 guides the fiberglass tape 1 to prevent it from being loose and clumped together in front of the wire drawing device 400, thus affecting the input of the fiberglass tape 1.

[0044] This plastic pellet production system allows different fiberglass tapes 1 to be added to the melting furnace 100 simultaneously in the required proportions, thereby reducing the investment in fiberglass addition equipment, saving costs, and reducing the space occupied by the equipment, thus improving production convenience.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
