[0002] Plastics have many advantages such as excellent electrical insulation performance, low price, good processing performance, recyclability and environmental protection, so they are widely used in practical applications. When preparing plastic products, some plastic products need to be cooled and formed. For example, after plastic particles are formed by extrusion and cutting operations, the plastic particles need to be cooled in time so that the plastic particles form multiple individual individuals to ensure the quality of the finished product.

[0003] In the prior art, when performing cooling operations, most of the plastic particles are uniformly poured into a container with air holes, and then a device similar to a blower is used to quickly drive air through the container, thereby achieving an efficient cooling effect. However, the prior art can only perform a simple blowing operation during cooling, and it is impossible to avoid the plastic particles sticking to and clogging some of the air holes during the cooling process, thereby affecting the subsequent cooling effect.

[0026] like Figure 1 , Figure 5 , Figure 6 and Figure 8 As shown:

[0027] It includes an L-shaped rod 302 and a fixed seat 501, the L-shaped rod 302 is slidably connected with a moving part 101, the moving part 101 is fixedly connected with a cooling arc plate 102, the cooling arc plate 102 is provided with a plurality of air holes 103, and each air hole 103 is provided with an arc chamfer 107 on the lower side, the fixed seat 501 is slidably connected with a matching rod 502, the matching rod 502 is slidably connected with a plurality of dredging rods 503, a first compression spring is fixedly connected between each dredging rod 503 and the matching rod 502, and a second compression spring is fixedly connected between the matching rod 502 and the fixed seat 501.

[0028] A blower device capable of rapidly blowing air is connected to the lower side of the L-shaped rod 302, and then the cut plastic particles are poured into the cooling arc plate 102, and then the moving part 101 is operated to slide back and forth on the L-shaped rod 302 at a high frequency, so that the plastic particles on the cooling arc plate 102 are continuously and spontaneously rolled in the cooling arc plate 102, so that the plastic particles can be evenly contacted with the surrounding air, thereby achieving efficient cooling operation, and at the same time, the blower device can be started, and the blower device is used to efficiently blow air through the multiple air holes 103 to contact the plastic particles, so as to further improve the cooling effect of the plastic particles and complete the efficient cooling operation;

[0029] When the movable part 101 is operated to slide on the L-shaped rod 302, the matching rod 502 will be subjected to the elastic force of the second compression spring and then adaptively slide on the fixed seat 501, so as to always contact with the lower side of the cooling arc plate 102. During the sliding process of the movable part 101, the movable part 101 will move relatively with the matching rod 502. During this process, the plurality of dredging rods 503 will always be subjected to the elastic force of the plurality of first compression springs to be inserted into the plurality of air holes 103 in sequence, so as to lift up some plastic particles that may be adhered in the air holes 103 or on the upper side of the air holes 103, so as to avoid the blockage of the plurality of air holes 103 during the cooling operation, so that the plurality of air holes 103 can always be in a state where air can pass smoothly, thereby ensuring that the air blown out by the air blowing device can smoothly contact with the plastic particles on the cooling arc plate 102, and ensuring the normal operation of efficient cooling.

[0030] The arc chamfer 107 provided on each air hole 103 enables the clearing operation of plastic particles that may be stuck in the air hole 103 or on the upper side of the air hole 103 to be completed when the clearing rod 503 is inserted into the air hole 103. Then, when the moving part 101 continues to slide on the L-shaped rod 302, the clearing rod 503 can be pushed by the arc chamfer 107 to slide smoothly out of the air hole 103, thereby facilitating subsequent continuous cleaning operations.

[0031] like Figure 2 , Figure 3 and Figure 8 As shown:

[0032] It also includes a rotating shaft 201 rotatably connected to the cooling arc plate 102, a plurality of flap plates 202 are fixedly connected to the rotating shaft 201, each flap plate 202 is provided with an oblique groove 204, each flap plate 202 is provided with a rectangular groove 203, and a first motor capable of driving the rotating shaft 201 to rotate is fixedly connected to the cooling arc plate 102.

[0033] During the cooling operation, the rotating shaft 201 can be operated to rotate continuously on the cooling arc plate 102 at the same time, and then the plastic particles on the cooling arc plate 102 can be turned continuously by using multiple flipping plates 202, so as to further facilitate the uniform contact between the plastic particles and the blowing air, and complete the efficient cooling operation. The shape of the cooling arc plate 102 is set so that the plastic particles will always accumulate in the middle position of the cooling arc plate 102, so as to facilitate the continuous turning operation;

[0034] The rectangular grooves 203 and the oblique grooves 204 on each flip plate 202 enable the plastic particles to automatically slide along the oblique grooves 204 after being flipped up by a flip plate 202 and rotated to a horizontal position as the rotating shaft 201 continues to rotate, thereby allowing the plastic particles to automatically fall from the rectangular grooves 203, thereby further improving the suspended flipping effect of the plastic particles, allowing the plastic particles to contact the blowing air more comprehensively and evenly, further improving the cooling effect.

[0035] like Figure 5 As shown:

[0036] An auxiliary ball 504 fixedly connected to the mating rod 502 is also included.

[0037] The setting of the auxiliary ball 504 ensures that during the movement of the moving part 101, the cooperating rod 502 can always be subjected to the elastic force of the second compression spring and thus adaptively slide on the fixed seat 501, so that the auxiliary ball 504 always rests against the lower side of the cooling arc plate 102, ensuring that the cooperating rod 502 can fully contact all positions of the cooling arc plate 102, thereby ensuring that the multiple clearing rods 503 can smoothly carry out subsequent cleaning operations on the multiple air holes 103.

[0038] like Figure 4 and Figure 8 As shown:

[0039] It also includes a fixed rod 401, a slider 403 is slidably connected to the fixed rod 401, a rotating rod 404 is rotatably connected to the slider 403, a third compression spring is fixedly connected between the moving part 101 and the L-shaped rod 302, a first electric push rod that can push the slider 403 to slide is fixedly connected to the fixed rod 401, and a second motor that can drive the rotating rod 404 to rotate is fixedly connected to the slider 403.

[0040] When the moving part 101 needs to be operated to slide back and forth at high frequency on the L-shaped rod 302, the rotating rod 404 can be operated to rotate on the slider 403, so that the rotating rod 404 can move the moving part 101 to slide on the L-shaped rod 302 to overcome the elastic force of the third compression spring. When the rotating rod 404 rotates to separate from the moving part 101, the moving part 101 will be quickly reset by the elastic force of the third compression spring, and then the moving part 101 can be made to slide back and forth at high frequency as the rotating rod 404 continues to rotate.

[0041] At the same time, in the process of using the rotating rod 404 to complete the driving operation, the slider 403 can be operated to slide on the fixed rod 401, thereby changing the distance that the rotating rod 404 can move the moving part 101 to slide, thereby changing the high-frequency reciprocating sliding amplitude of the moving part 101, thereby making the high-frequency reciprocating sliding process of the moving part 101 more diverse, and further facilitating the plastic particles to evenly contact with the flowing air, thereby improving the cooling effect.

[0042] like Figure 1 , Figure 4 and Fig. 9 As shown:

[0043] It also includes a friction strip 402 fixedly connected to the fixed rod 401 . The moving part 101 is rotatably connected with a detection part 104 . The detection part 104 contacts the friction strip 402 . The moving part 101 is fixedly connected with an angle sensor. The moving end of the angle sensor is fixedly connected to the detection part 104 .

[0044] During the sliding of the moving part 101, the detection part 104 will always be in contact with the friction strip 402, so that the detection part 104 will continue to slide on the moving part 101. At this time, the sliding condition of the moving part 101 can be always monitored by the angle sensor, and when a device failure causes the moving part 101 to be unable to move normally, the situation can be discovered in time, so as to facilitate timely operation and maintenance operations.

[0045] like Figure 2 As shown:

[0046] It also includes a fixing base 301 , on which an L-shaped rod 302 is slidably connected.

[0047] When performing cooling operation, the L-shaped rod 302 can be simultaneously operated to slide up and down on the fixed seat 301, thereby further increasing the movement range of the plastic particles in the cooling arc plate 102, expanding the movable range of the plastic particles, and further facilitating the uniform contact between the plastic particles and the flowing air, thereby improving the cooling effect.

[0048] like Figure 2 , Figure 7 and Figure 8 As shown:

[0049] It also includes a transverse plate 601, on which a plurality of arc blocks 602 are fixedly connected, a transmission rod 106 is slidably connected to the movable part 101, the transmission rod 106 can contact the arc blocks 602, a fourth compression spring is fixedly connected between the fixed seat 301 and the L-shaped rod 302, and a second electric push rod is fixedly connected to the movable part 101, which can push the transmission rod 106 to slide.

[0050] During the sliding operation of the moving part 101, the transmission rod 106 on the moving part 101 will pass through the positions of the plurality of arc blocks 602 in sequence. Whenever the transmission rod 106 contacts an arc block 602, it will gradually push the L-shaped rod 302 on the fixed seat 301 to overcome the elastic force of the fourth compression spring and slide upward on the fixed seat 301. When the transmission rod 106 is separated from the arc block 602, the L-shaped rod 302 will quickly slide downward on the fixed seat 301 to reset. During the sliding operation of the moving part 101, the L-shaped rod 302 will slide back and forth on the fixed seat 301 continuously, which further facilitates the uniform contact between the plastic particles and the flowing air, thereby improving the cooling effect.

[0051] When the rotating rod 404 completes one movement, thereby causing the moving part 101 to slide and reset, the transmission rod 106 slides on the moving part 101 to a position offset from the multiple arc blocks 602, thereby avoiding interference between the transmission rod 106 and the multiple arc blocks 602 during the resetting process of the moving part 101, thereby ensuring that the resetting operation is carried out normally.

[0052] like Figure 8 As shown:

[0053] The heights of the arc blocks 602 gradually decrease from left to right.

[0054] The different height settings of the multiple arc blocks 602 can enable the moving part 101 to perform different degrees of up and down reciprocating sliding operations during the cooling process, thereby further allowing the plastic particles to roll randomly on the cooling arc plate 102, further facilitating uniform contact between the plastic particles and the flowing air, thereby improving the cooling effect.

[0055] like Figure 1 As shown:

[0056] The cooling arc plate 102 is fixedly connected with two connecting parts 105 , and each connecting part 105 is provided with two connecting threaded holes.

[0057] After completing the operation of adding plastic particles into the cooling arc plate 102, a cover body can be connected to the connecting part 105 by screwing bolts into multiple connecting threaded holes. In actual use, cover plates are also provided on the front and rear sides of the cooling arc plate 102 to prevent the plastic particles from slipping out. After the cover body is connected to the cooling arc plate 102, the plastic particles can be stably placed on the cooling arc plate 102, ensuring that subsequent cooling operations proceed smoothly.

[0058] The plastic product molding device is used in a molding method for plastic molding, and the method comprises the following steps:

[0059] Step 1: Connect a blasting device capable of rapidly blowing air to the lower side of the L-shaped rod 302, and pour the cut plastic particles into the cooling arc plate 102;

[0060] Step 2: Connect a cover to the connecting portion 105 by screwing bolts into a plurality of connecting threaded holes;

[0061] Step 3: Connect the fixing seat 501 to the lower side of the L-shaped rod 302 by screwing bolts into the fixing seat 501, and make the auxiliary ball 504 be in a position to contact the cooling arc plate 102;

[0062] Step 4: operate the rotating rod 404 to rotate continuously on the slider 403, and periodically operate the slider 403 to slide on the fixed rod 401;

[0063] Step 5: Make the rotating shaft 201 rotate continuously on the cooling arc plate 102;

[0064] Step 6: After cooling, take out the plastic pellets to complete the molding operation.
