Description

Technical Field

[0001] This utility model relates to the field of injection blow molding machine technology, and in particular to a demolding and flipping device for injection blow molding machines. Background Technology

[0002] Injection blow molding machines are commonly used in the plastics processing industry. They are typically used to blow plastic products into hollow shapes, such as bottles, umbrellas, and toys, in the air. In the food, pharmaceutical, and cosmetic industries, injection blow molding machines are often used to produce various packaging bottles. After production, these bottles sometimes need to be demolded and flipped for cleaning and other deep processing. However, existing demolding and flipping devices have low flipping efficiency, affecting the overall efficiency of packaging bottle production. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a demolding and flipping device for injection blow molding machines, which effectively solves the deficiencies of the prior art.

[0004] The purpose of this utility model is achieved through the following technical solution: a demolding and turning device for an injection blow molding machine, including a turning chamber, a turning groove is provided inside the turning chamber, a transfer platform is provided at one end of the turning chamber, a first conveyor belt is provided at the end of the transfer platform, a second conveyor belt is provided on both sides of the bottom of the other end of the turning chamber, and a third conveyor belt is provided above the second conveyor belt.

[0005] Optionally, the shape of the end of the tilting groove is adapted to the shape of the product produced by the injection blow molding machine, the interior of the tilting groove is spiral, and the tilting groove rotates 180 degrees in the slide within the tilting chamber.

[0006] The above technical solution involves setting a spiral-shaped turning groove inside the turning chamber. The product produced by the injection blow molding machine after demolding is introduced into the turning groove and gradually rotated 180 degrees under the action of the spiral arc surface inside the turning groove to complete the turning. This achieves rapid turning of the product produced by the injection blow molding machine. Moreover, the relative clamping turning method can avoid damage to the produced product due to clamping during the clamping process.

[0007] Optionally, shrinkage grooves are provided on both sides of the front end of the flipping groove, and a fan is fixedly connected inside the shrinkage groove, with the air outlet of the fan facing the inside of the flipping groove.

[0008] The above technical solution is adopted: by setting a fan at the front end of the flipping groove, the blow molding product entering the flipping groove is subjected to air force, so that the blow molding product can slide through the flipping groove and complete the flipping process of the blow molding product. The air force generated by the fan can dissipate heat and cool down the blow molding product that has just been demolded, so that the blow molding product can cool down and solidify quickly, and avoid damage to the blow molding product during the flipping process.

[0009] Optionally, the internal friction coefficient of the flipping groove is less than 0.5, and heat dissipation holes are provided at the top and bottom of the flipping groove. The diameter of the heat dissipation holes is less than one millimeter, and the heat dissipation holes are evenly distributed on the flipping groove.

[0010] The above technical solution is adopted to reduce the friction coefficient of the inner wall of the tilting groove, so that the impact of friction on the product can be reduced during the sliding process of the injection blown product in the tilting groove. This allows the injection blown product to complete the tilting process smoothly and avoids the situation where the injection blown product is blocked inside the tilting groove due to friction. The heat dissipation holes can make the airflow generated by the blower flow more smoothly and prevent the heat carried by the injection blown product from being discharged from the heat dissipation holes in time.

[0011] Optionally, the second conveyor belt is inclined, the shape of the inclined surface of the second conveyor belt is adapted to the bottom inclined surface of the injection blown product after it is flipped, and the coefficient of friction between the second conveyor belt and the injection blown product is greater than two.

[0012] The above technical solution is adopted: by setting a second conveyor belt with two inclined sides at the discharge port of the tilting tank, it can clamp the bottom of the injection blown product for conveying, avoiding the situation where the bottom of the injection blown product is unstable and inconvenient to convey.

[0013] Optionally, the third conveyor belt is vertical, and the distance of the third conveyor belt is adapted to the width of the injection blown product.

[0014] By adopting the above technical solution, a third conveyor belt can be set above the second conveyor belt to limit the conveying of the injection blow molding product.

[0015] Optionally, the top of the transfer platform is a slope, and the two ends of the transfer platform are respectively connected to the flipping groove and the first conveyor belt, with the end of the transfer platform closer to the first conveyor belt being higher than the other end.

[0016] This utility model has the following advantages:

[0017] 1. This injection blow molding machine uses a demolding and turning device. A spiral turning groove is set inside the turning chamber. The product produced by the injection blow molding machine after demolding is guided into the turning groove. Under the action of the spiral arc surface within the turning groove, it gradually rotates 180 degrees to complete the turning, achieving rapid turning of the product produced by the injection blow molding machine. This relatively clamping turning method avoids damage to the produced product during clamping. A fan is installed at the front end of the turning groove to apply airflow to the injection blow molding product entering the turning groove, allowing the product to slide through the turning groove and complete the turning process. The airflow generated by the fan also dissipates heat and cools the newly demolded injection blow molding product, allowing it to cool and solidify quickly, preventing damage during the turning process.

[0018] 2. The blow molding machine uses a demolding and turning device, which limits the coefficient of friction of the inner wall of the turning groove, so that the blow molding product can reduce the impact of friction on the product during the sliding process in the turning groove, and the blow molding product can be turned smoothly. This avoids the blow molding product from being blocked inside the turning groove due to friction. The heat dissipation holes can make the airflow generated by the blower flow more smoothly, and prevent the heat carried by the blow molding product from being discharged from the heat dissipation holes in time.

[0019] 3. The blow molding machine uses a demolding and turning device. By setting a second conveyor belt with two inclined sides at the discharge port of the turning groove, it can clamp the bottom of the blow molding product for conveying, avoiding the situation where the bottom of the blow molding product is unstable and inconvenient to convey. By setting a third conveyor belt above the second conveyor belt, it can assist in limiting the conveying of the blow molding product. Attached Figure Description

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] like Figures 1 to 6As shown, a demolding and turning device for an injection blow molding machine includes a turning chamber 1, a turning groove 2 inside the turning chamber 1, a transfer platform 3 at one end of the turning chamber 1, a first conveyor belt 4 at the end of the transfer platform 3, a second conveyor belt 5 on both sides of the bottom of the other end of the turning chamber 1, and a third conveyor belt 6 above the second conveyor belt 5.

[0029] Example 1: The shape of the end of the flipping groove 2 is adapted to the shape of the product produced by the injection blow molding machine. The inside of the flipping groove 2 is spiral. The flipping groove 2 rotates 180 degrees in the slide of the flipping chamber 1. By setting the spiral flipping groove 2 inside the flipping chamber 1, the product produced by the injection blow molding machine after demolding is introduced into the flipping groove 2. Under the action of the spiral arc surface in the flipping groove, it gradually rotates 180 degrees to complete the flipping, realizing the rapid flipping of the product produced by the injection blow molding machine. Moreover, the flipping method of relative clamping can avoid damage to the produced product due to clamping during the clamping process.

[0030] Example 2: Shrinkage grooves 7 are provided on both sides of the front end of the flipping groove 2. Fans 8 are fixedly connected inside the shrinkage grooves 7. The air outlets of the fans 8 face the inside of the flipping groove 2. By setting the fans 8 at the front end of the flipping groove 2, air force is applied to the injection blown product entering the flipping groove 2, so that the injection blown product can slide through the flipping groove 2 to complete the flipping process of the injection blown product. The air force generated by the fans 8 can dissipate heat and cool down the injection blown product that has just been demolded, so that the injection blown product cools down and solidifies quickly, avoiding damage to the injection blown product during the flipping process.

[0031] Example 3: The internal friction coefficient of the tilting groove 2 is less than 0.5. Heat dissipation holes 9 are provided at the top and bottom of the tilting groove 2. The diameter of the heat dissipation holes 9 is less than one millimeter. The heat dissipation holes 9 are evenly distributed on the tilting groove 2. By limiting the friction coefficient of the inner wall of the tilting groove 2, the influence of friction on the product can be reduced during the sliding process of the injection blown product in the tilting groove 2. This allows the injection blown product to complete the tilting process smoothly and avoids the situation where the injection blown product is blocked inside the tilting groove due to friction. The heat dissipation holes 9 can make the airflow generated by the blower 8 flow more smoothly and prevent the heat carried by the injection blown product from being discharged from the heat dissipation holes 9 in time.

[0032] Example 4: The second conveyor belt 5 is inclined. The inclined shape of the second conveyor belt 5 is adapted to the bottom inclined surface of the injection blown product after it is flipped. The friction coefficient between the second conveyor belt 5 and the injection blown product is greater than two. By setting the second conveyor belt 5 with inclined sides at the discharge port of the flipping trough 2, it can clamp the bottom of the injection blown product for conveying, avoiding the situation where the bottom of the injection blown product is unstable and inconvenient to convey.

[0033] Example 5: The third conveyor belt 6 is in a vertical state, and the distance of the third conveyor belt 6 is adapted to the width of the injection blown product. By setting the third conveyor belt 6 above the second conveyor belt 5, the injection blown product can be conveyed in a limited position.

[0034] Example 6: The top of the transfer platform 3 is a slope, and the two ends of the transfer platform 3 are respectively connected to the flipping groove 2 and the first conveyor belt 4. The end of the transfer platform 3 closer to the first conveyor belt 4 is higher than the other end.

[0035] The working principle of this utility model is as follows:

[0036] S1. A spiral-shaped turning groove 2 is set inside the turning chamber 1. The product produced by the injection blow molding machine after demolding is introduced into the turning groove 2. Under the action of the spiral arc surface in the turning groove, it gradually rotates 180 degrees to complete the turning, realizing the rapid turning of the product produced by the injection blow molding machine. Moreover, the turning method of relative clamping and turning can avoid damage to the produced product due to clamping during the clamping process.

[0037] S2. A fan 8 is installed at the front end of the flipping groove 2 to apply air force to the injection blown product entering the flipping groove 2, so that the injection blown product can slide through the flipping groove 2 to complete the flipping process of the injection blown product. The air force generated by the fan 8 can dissipate heat and cool down the injection blown product that has just been demolded, so that the injection blown product can cool down and solidify quickly, and avoid damage to the injection blown product during the flipping process.

[0038] Compared with the prior art, the present invention has the following advantages:

[0039] 1. This injection blow molding machine uses a demolding and turning device. A spiral turning groove 2 is set inside the turning chamber 1. The product produced by the injection blow molding machine after demolding is guided into the turning groove 2. Under the action of the spiral arc surface within the turning groove, it gradually rotates 180 degrees to complete the turning, achieving rapid turning of the product produced by the injection blow molding machine. This relatively clamping turning method avoids damage to the produced product during clamping. A fan 8 is installed at the front end of the turning groove 2 to apply airflow to the injection blow molding product entering the turning groove 2, allowing the product to slide through the turning groove 2 and complete the turning process. The airflow generated by the fan 8 can also dissipate heat and cool the newly demolded injection blow molding product, allowing it to cool and solidify quickly, preventing damage during the turning process.

[0040] 2. The demolding and turning device of this injection blow molding machine reduces the friction coefficient of the inner wall of the turning groove 2, thereby reducing the impact of friction on the product during the sliding process of the injection blow molding product in the turning groove 2. This allows the injection blow molding product to complete the turning process smoothly and avoids the situation where the injection blow molding product is blocked inside the turning groove due to friction. The heat dissipation hole 9 allows the airflow generated by the blower 8 to flow more smoothly, preventing the heat carried by the injection blow molding product from being discharged from the heat dissipation hole 9 in a timely manner.

[0041] 3. The blow molding machine uses a demolding and turning device. By setting a second conveyor belt 5 with two inclined sides at the discharge port of the turning groove 2, it can clamp the bottom of the blow molding product for conveying, avoiding the situation where the bottom of the blow molding product is unstable and inconvenient to convey. By setting a third conveyor belt 6 above the second conveyor belt 5, it can assist in limiting the conveying of the blow molding product.
