Description

Technical Field

[0001] This utility model belongs to the technical field of plastic pelletizing machines, and specifically relates to a pelletizing head used in plastic pelletizing machines. Background Technology

[0002] A plastic pelletizer is a type of pelletizer mainly used for processing waste plastic films, woven bags, agricultural convenience bags, basins, buckets, beverage bottles, furniture, daily necessities and other plastic products. It is suitable for most common waste plastics. After the waste plastics are processed into strips, they are cut into pellets, which requires the use of a pelletizer head.

[0003] For example, in Chinese utility model patent CN213353086U, entitled "A Pelletizer Head for a Plastic Pelletizer," a pelletizer head, a second housing, and a receiving box are included. The second housing is fixedly connected to the lower center of the pelletizer head, and the receiving box is fixedly connected to the lower part of the second housing. Although the above-mentioned prior art uses a tipping bucket structure between the tamping plate, the telescopic rod, the force plate, and the movable rod to make the cut plastic pellets fall and collect at the bottom when cutting inside the pelletizer head, the plastic strips formed are easily deformed due to the relatively soft plastic inside during the cutting process. This makes the plastic inconvenient to store. In order to make the cut pellets quickly set, a pelletizer head for plastic pelletizers is now needed. Utility Model Content

[0004] The purpose of this invention is to provide a pelletizer head for plastic pelletizers that has a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A pelletizing head for a plastic pelletizer includes a pelletizing box. A rotating shaft is rotatably mounted on the inner center of the pelletizing box. A servo motor for driving the rotating shaft is fixedly mounted on the rear side of the pelletizing box. A fixed sleeve is fixedly fitted on the outer side of the rotating shaft. Several cutting blade assemblies are arranged on the outer circumference of the fixed sleeve. A separating component that cooperates with the several cutting blade assemblies is provided on the inner side wall of the pelletizing box. A wetting component that cooperates with the several cutting blade assemblies is provided on the other side of the side wall of the pelletizing box. A cooling component is provided on one side of the bottom of the pelletizing box. An air outlet that cooperates with the cooling component is opened on the other side of the bottom of the pelletizing box.

[0007] As a further optimization of this utility model, the cutter assembly includes a connecting rod fixedly disposed on the outside of the fixed cylinder, a mounting cylinder fixedly disposed at one end of the connecting rod, a cutter slidably inserted into one side of the mounting cylinder, and a plurality of positioning bolts for fixing the cutter disposed on the mounting cylinder.

[0008] As a further optimization of this utility model, the separating component includes a fixing plate fixedly disposed in the middle of the inner sidewall of the pelletizing box, a plurality of first separating plates fixedly disposed on the upper side of the fixing plate, and a plurality of second separating plates fixedly disposed on the lower side of the fixing plate.

[0009] As a further optimization of this utility model, the wetting component includes a water tank fixedly installed on the outer wall of the pelletizing box, and a water trough pipe fixedly installed through the side wall of the pelletizing box is connected to one side of the bottom of the water tank, and a sponge block is provided on the inner side of the water trough pipe.

[0010] As a further optimization of this utility model, the cooling assembly includes a mounting plate fixedly disposed on one side of the bottom of the pelletizing box, and a plurality of air blowing pipes that cooperate with the air outlet are fixedly disposed on the inner side of the mounting plate, and one end of the plurality of air blowing pipes is connected to a main air inlet pipe located outside the pelletizing box.

[0011] As a further optimization of this utility model, a feed hopper is provided on one side of the top of the pelletizing box, and a discharge port located below the feed hopper is provided on one side of the bottom of the pelletizing box.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, multiple rotating cutters enable rapid and continuous cutting of the formed strip-shaped plastic, improving cutting efficiency. Multiple first and second partition plates separate the multiple formed plastic strips, preventing them from sticking together during cutting and affecting the cutting effect of the plastic particles. Multiple air blowers further cool the falling plastic particles, improving the forming efficiency of the plastic particles and preventing unshaped plastic particles from hitting the bottom, causing deformation and affecting storage performance.

[0014] 2. In this utility model, the sponge block located inside the water tank pipe allows the water inside the water tank to be absorbed into the sponge block. When the cutter rotates to one side of the sponge block, it will squeeze the sponge block, causing the water in the sponge block to dissipate the heat from the cutter, thus cooling the cutter. This makes it easier for the plastic particles to adhere to the cutter during the cutting process, improving the material feeding effect. Attached Figure Description

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example

[0025] like Figure 1 , Figure 4 , Figure 5As shown, the pelletizing head for a plastic pelletizer includes a pelletizing box 1. A feed hopper 2 is provided on one side of the top of the pelletizing box 1, and a discharge port 3 located below the feed hopper 2 is provided on one side of the bottom of the pelletizing box 1. A rotating shaft 4 is rotatably provided in the middle of the inner side of the pelletizing box 1. A servo motor 11 for driving the rotating shaft 4 is fixedly provided on the rear side of the pelletizing box 1. A fixing cylinder 5 is fixedly sleeved on the outer side of the rotating shaft 4. Several cutting blade assemblies 6 are provided on the outer circumference of the fixing cylinder 5. The cutting blade assembly 6 includes a connecting rod 601 fixedly provided on the outer side of the fixing cylinder 5. A mounting cylinder 602 is fixedly provided at one end of the connecting rod 601. A cutting blade 603 is slidably inserted into one side of the mounting cylinder 602. In this embodiment, eight cutting blades 603 are provided. The specific number can be adjusted according to the process. Several positioning bolts 604 for fixing the cutting blades 603 are provided on the mounting cylinder 602. The positioning bolts 604 facilitate the replacement of the cutting blades 603.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 7 As shown, a wetting component 7 is provided on the other side of the side wall of the pelletizing box 1, which cooperates with several cutting blade assemblies 6. The wetting component 7 includes a water tank 701 fixedly installed on the outer side wall of the pelletizing box 1. A water trough pipe 702 is fixedly connected to the bottom side of the water tank 701 and passes through the side wall of the pelletizing box 1. A sponge block 703 is provided on the inner side of the water trough pipe 702. When in use, cooling water is added to the water tank 701, which allows the cooling water to penetrate into the interior of the sponge block 703, which facilitates the subsequent cooling of the cutting blade 603.

[0027] like Figure 1 , Figure 5 As shown, the inner wall of the pelletizing box 1 is provided with a separating component 8 that cooperates with several cutting blade assemblies 6. The separating component 8 includes a fixing plate 801 fixedly installed in the middle of the inner wall of the pelletizing box 1. Several first separating plates 802 are fixedly installed on the upper side of the fixing plate 801. The several first separating plates 802 are arranged horizontally and vertically at equal intervals. Several second separating plates 803 are fixedly installed on the lower side of the fixing plate 801. The several second separating plates 803 are arranged horizontally and vertically at equal intervals. The several second separating plates 803 correspond vertically to the several first separating plates 802, that is, the second separating plates 803 are located directly below the first separating plates 802. In use, the shaped strip plastic is passed between two adjacent first separating plates 802, which can separate multiple shaped strip plastics and prevent them from sticking together.

[0028] like Figure 1 , Figure 6As shown, a cooling assembly 10 is provided on one side of the bottom of the pelletizing box 1. The cooling assembly 10 includes a mounting plate 1001 fixedly installed on one side of the bottom of the pelletizing box 1. Several air blowing pipes 1002 that cooperate with the air outlet 9 are fixedly installed on the inner side of the mounting plate 1001. One end of the several air blowing pipes 1002 is connected to the air inlet main pipe 1003 located outside the pelletizing box 1. A fan (not shown in the figure) is connected to one side of the air inlet main pipe 1003. An air outlet 9 that cooperates with the cooling assembly 10 is opened on the other side of the bottom of the pelletizing box 1. In use, the fan draws air into the interior of the air inlet main pipe 1003, and then blows it into the interior of the pelletizing box 1 through the multiple air blowing pipes 1002, so that the cut plastic pellets are cooled, preventing the unshaped plastic pellets from hitting the bottom, causing the plastic pellets to deform and affecting the storage effect.

[0029] It should be noted that, in use, the pelletizing head for the plastic pelletizer passes multiple shaped strips of plastic sequentially through several first partition plates 802. Then, the servo motor 11 drives the rotating shaft 4 to rotate, which in turn drives the fixed cylinder 5 to rotate. This causes multiple connecting rods 601 on the outside of the fixed cylinder 5 to rotate, resulting in the mounting cylinder 602 at one end of the connecting rod 601 and the cutter 603 rotating together. This allows the strips of plastic between the first partition plates 802 to be cut into pellets. During the cutting process, when the cutter 603 rotates to… When the sponge block 703 is pressed to one side, the water in the sponge block 703 will dissipate the heat in the cutter 603, thus cooling the cutter 603. This makes it easier for the plastic particles to adhere to the cutter 603 during the subsequent cutting process, improving the feeding efficiency. The fallen plastic particles are then drawn into the air inlet duct 1003 by the fan, and then blown into the inside of the pelletizing box 1 through multiple air blowers 1002, which cools the cut plastic particles and improves the shaping efficiency of the plastic particles.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
