[0025] The following is combined with Figure 1-4 The utility model is described in further detail.

[0026] The utility model embodiment discloses a preform injection molding machine, referring to Figure 1 , including an injection molding body 1 and a discharge port 11 opened on one side of the injection molding body 1. The product after injection molding in the injection molding body 1 can be discharged through the discharge port 11 for discharge. The injection molding body 1 and the discharge port 11 constitute the existing preform injection molding machine, and its internal structure and principle have been disclosed and will not be described in detail here.

[0027] Reference Figure 1-3 A material collecting box 2 is fixedly provided on one side of the injection molding machine body 1, and a screen frame 3 is slidably provided in the middle of the inner wall of the material collecting box 2 and is located below the discharge port 11. Both sides of the outer wall of the screen frame 3 are in contact with the inner wall of the material collecting box 2. The material collecting box 2 can support and limit the screen frame 3, and the screen frame 3 can catch the products that fall from the discharge port 11.

[0028] Reference Figure 2-3A sponge block 31 is fixedly provided at the bottom of the screen frame 3 and abuts against the bottom of the inner wall of the collection box 2. The sponge block 31 can not only cushion the product and the screen frame 3 when the product falls and collides with the screen frame 3, but also raise the screen frame 3 to increase the gap between the screen frame 3 and the collection box 2.

[0029] Reference Figure 2-3 Fans 21 facing the screen frame 3 are fixedly arranged in the openings opened on both sides of the aggregate box 2. The aggregate box 2 can support and fix the fan 21. A wind flow channel is formed in the gap between the aggregate box 2 and the screen frame 3. The fan 21 can blow air to cool down the products in the screen frame 3, and the wind energy can flow in the gap between the aggregate box 2 and the screen frame 3, and cooperate with the mesh holes in the screen frame 3, so that the wind energy can dissipate heat and cool down the products in the screen frame 3 more evenly.

[0030] Reference Figure 2 A positioning mechanism is provided on the top of the screen frame 3, and the positioning mechanism includes positioning rods 32 fixed on both sides of the top of the screen frame 3, and rollers 33 rotatably arranged at one end of the positioning rods 32, and the two rollers 33 are respectively in contact with the two sides of the inner wall of the aggregate box 2, and the rollers 33 are located above the fan 21. The positioning rods 32 and the rollers 33 can both position the screen frame 3 in the aggregate box 2, so that the screen frame 3 inserted into the aggregate box 2 can only be located in the middle of the aggregate box 2, and the screen frame 3 in the aggregate box 2 will always be located at the discharging position of the discharge port 11, which is convenient for the product in the discharge port 11 to fall into the screen frame 3, and the rollers 33 can reduce the resistance and wear between the positioning mechanism and the aggregate box 2 when the screen frame 3 is plugged in and out by rotating.

[0031] Reference Figure 2 Both sides of the top of the material collecting box 2 are provided with inclined grooves 22 located above the roller 33. The inclined grooves 22 can guide the roller 33, so that when the screen frame 3 needs to be installed and inserted into the material collecting box 2, it is easier for the roller 33 and the screen frame 3 to enter the material collecting box 2 under the guidance of the inclined grooves 22.

[0032] Reference Figure 1 and Figure 4 A height adjustment mechanism is provided at the bottom of the injection molding machine body 1, and the height adjustment mechanism includes a plurality of threaded rods 4 fixedly arranged at the bottom of the injection molding machine body 1, and a fixed sleeve rod 41 with threads arranged on the outer wall of the bottom end of the threaded rod 4. People can drive the threaded rod 4 and other components on the top to rise and fall by rotating the fixed sleeve rod 41, thereby realizing the height adjustment of the injection molding machine body 1 and the preform injection molding machine as a whole, which can meet the production needs at different heights.

[0033] Reference Figure 1 and Figure 4A self-locking universal wheel 42 is installed at the bottom of the fixed sleeve rod 41, and a fluorescent paint is fixed on the outer wall of the top of the self-locking universal wheel 42. The self-locking universal wheel 42 can not only facilitate the overall movement of the bottle embryo injection molding machine, but also reduce the resistance of the fixed sleeve rod 41 when rotating by its own rotation. People can find the self-locking universal wheel 42 and the bottle embryo injection molding machine by fluorescence under dark conditions.

[0034] Reference Figure 1 and Figure 4 A grip 43 is rotatably provided on the outer wall of the fixed sleeve rod 41, and anti-skid patterns are provided on both sides of the grip 43. People can drive the fixed sleeve rod 41 to rotate by holding the grip 43, and the grip 43 can be folded after rotating as it naturally hangs down due to gravity, and does not take up space. The anti-skid patterns can increase the friction between people's hands and the grip 43, making it difficult for people to slip when holding the grip 43.

[0035] Reference Figure 1 and Figure 4 A limit block 44 is fixedly provided on the outer wall of the fixed sleeve rod 41, and the bottom of the limit block 44 cooperates with the rotating end of the handle rod 43 to abut against the limit block 44. The limit block 44 can limit the handle rod 43 after rotation, so that the handle rod 43 can be turned to and kept horizontal, and people can use the horizontal handle rod 43 to drive the fixed sleeve rod 41 to rotate.

[0036] The implementation principle of a preform injection molding machine according to an embodiment of the utility model is as follows:

[0037] When in use, the product after injection molding in the injection molding machine body 1 will be discharged through the discharge port 11, and the mesh frame 3 can catch the product dropped from the discharge port 11. At this time, the sponge block 31 will cushion the product and the mesh frame 3 together when the product falls and collides with the mesh frame 3.

[0038] At the same time, the fan 21 is turned on, and the fan 21 can blow air to cool the products in the mesh frame 3, and the larger gap between the collection box 2 and the mesh frame 3 can form a wind channel to cool the products in the mesh frame 3 more evenly. After a batch of products are accumulated in the mesh frame 3, people can pull out the mesh frame 3 from the collection box 2 as a whole and take it out, which not only avoids the trouble of people taking products one by one, but also prolongs the cooling time of the products;

[0039] After the products in the screen frame 3 are cooled and taken out, they can be put into the next processing more quickly. Then people can insert the screen frame 3 back into the collection box 2. At this time, under the guidance of the roller 33 of the inclined groove 22, the rotation of the roller 33 and the connection of the positioning rod 32 can position the screen frame 3 entering the collection box 2, so that the inserted screen frame 3 returns to the original position in the collection box 2, which is convenient for the screen frame 3 to catch the next batch of products dropped from the discharge port 11 from the same position.

[0040] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
