Description

Technical Field

[0001] This utility model relates to the field of blow molding equipment, specifically to a blow molding device that facilitates material feeding. Background Technology

[0002] A blow molding machine is a plastic processing machine that sprays liquid plastic and uses the air force of the machine to blow the plastic body into a mold cavity of a certain shape to make a product. The first step in blow molding is to feed the material.

[0003] Impurities in the material cannot be filtered during the feeding process. These impurities entering the blow molding machine not only affect the quality of the blow-molded products but also easily damage the machine, hindering its effective use and limiting its application. Therefore, the material is filtered before feeding. However, current filtration devices only filter impurities larger than material particles, failing to filter impurities smaller than material particles. Consequently, the filtration effect is not perfect. Therefore, it is necessary to filter both impurities larger than material particles and impurities smaller than material particles to improve the effective use of the blow molding machine and indirectly improve the convenience of feeding.

[0004] This invention proposes a blow molding device that facilitates material feeding, in order to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a blow molding device that facilitates material feeding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a blow molding device for easy feeding, comprising a processing cylinder, an inlet pipe connected to and communicating with the top end of the processing cylinder, an outlet pipe connected to and communicating with the bottom end of the inlet pipe, a screening mechanism installed inside the processing cylinder, a receiving mechanism connected to the outer surface of the processing cylinder, and a vibration mechanism installed on the outer wall of the processing cylinder.

[0007] By adopting the above technical solution, the vibration mechanism is activated, which vibrates the entire processing cylinder up and down, feeding the material into the inlet pipe. The material will be screened by the screening mechanism, so that impurities larger than the material and impurities smaller than the material can be removed together, improving the filtration effect of the material. Then, the material falls from the outlet pipe into the feed pipe of the blow molding machine, realizing the effect of material filtration and feeding.

[0008] As a preferred embodiment of this utility model, the screening mechanism includes a support plate, a first screen plate, a guide inclined plate, a second screen plate, and a first impurity outlet. Multiple staggered and inclined first screen plates are connected to the inner wall of the processing cylinder. The bottom end of each first screen plate is connected to the top end of a support plate. The outer wall of the support plate is connected to the inner wall of the processing cylinder. One end of each first screen plate is spaced from one side wall of the processing cylinder. The four sides of the second screen plate are connected to the four sides of the inner wall of the processing cylinder. A first impurity outlet is provided at the bottom end of the side wall of the processing cylinder. A guide inclined plate is connected to the inner wall of the support plate. The inclination direction of the guide inclined plate is different from that of the first screen plate. The opening of the first impurity outlet is flush with the bottom end of the second screen plate. The diameter of the screen holes in the second screen plate is larger than the diameter of the material, and the diameter of the screen holes in the first screen plate is smaller than the diameter of the material.

[0009] By adopting the above technical solution, the material entering the pipe will flow to the first screen plate and the second screen plate. At this time, the movement trajectory of the material is S-shaped. After the material passes through the first screen plate and the second screen plate for filtration, the impurities smaller than the material diameter will be screened and fall below the first screen plate, achieving the filtration effect of impurities smaller than the material diameter. The impurities larger than the material diameter will fall above the second screen plate and be discharged from the first impurity outlet, thereby achieving the filtration effect of impurities larger than the material diameter. The material passes through the second screen plate and falls into the discharge pipe, and then is fed into the feed pipe of the blow molding machine from the discharge pipe, completing the material feeding effect of the blow molding machine.

[0010] As a preferred embodiment of this utility model, the first sieve plate is located above the second sieve plate, and the inlet pipe is located above the upper end of the inclined surface of the uppermost first sieve plate.

[0011] By adopting the above technical solution, the screening sequence is changed from impurities smaller than the material diameter to impurities larger than the material diameter.

[0012] As a preferred embodiment of this utility model, the support plate is L-shaped.

[0013] By adopting the above technical solution, the support plate, the processing cylinder and the first screen plate can form a closed space, which facilitates the separation of impurities smaller than the material diameter from the material and particles larger than the material diameter.

[0014] As a preferred technical solution of this utility model, the storage mechanism includes a connecting pipe, a storage box, and a second waste material outlet. The side wall of the processing cylinder is connected to and communicates with multiple connecting pipes, and the outlet ends of the multiple connecting pipes are connected to and communicate with the storage box. The bottom end of the side wall of the storage box is provided with a second waste material outlet.

[0015] By adopting the above technical solution, the debris falling onto the guide ramp will flow to the connecting pipe. Utilizing the frustum shape of the connecting pipe, the inlet ends of the connecting pipes on both sides can guide the debris to flow into the same collection box, where it will be collected.

[0016] As a preferred technical solution of this utility model, the bottom end of the guide plate is flush with the feed port of the connecting pipe, and the side walls of the first impurity outlet and the second impurity outlet are both provided with a rotating door. The upper side wall of the outlet end of the connecting pipe located below is connected with a blocking plate. The connecting pipe is truncated pyramidal in shape.

[0017] By adopting the above technical solution, the revolving door is used to facilitate the removal of debris and to give time to replace the storage box. The obstruction ramp is used to prevent debris from falling into the connecting pipe located below. The frustum shape of the connecting pipe allows the inlet ends of the connecting pipes on both sides to guide the debris to flow into the same storage box and be collected by the storage box.

[0018] As a preferred embodiment of this utility model, the vibration mechanism includes a base plate, guide rods, springs, connecting plates, side plates, a motor, and a cam. Multiple guide rods are connected to the top of the base plate. The guide rods are T-shaped, and springs are connected to the top of the guide rods. A connecting plate is connected to the bottom of the springs. The side wall of the connecting plate is movably connected to the guide rods. The side wall of the connecting plate is connected to the bottom of the outer wall of the processing cylinder. A blow molding machine feed pipe is connected to the bottom of the base plate. A side plate is connected to one side wall of the base plate, and a motor is connected to the side wall of the side plate. A cam is connected to the output end of the motor, and the side wall of the cam can contact the top of the connecting plate.

[0019] By adopting the above technical solution, the motor is started, which drives the cam to rotate. The cam presses and releases the connecting plate in a cycle. The connecting plate presses down on the spring, which is compressed. At the same time, the connecting plate drives the processing cylinder to move downward. Then, the cam releases the connecting plate, and the spring pulls the connecting plate up, causing the processing cylinder to move upward. This achieves the effect of vibrating the processing cylinder up and down, allowing the first and second screen plates inside the processing cylinder to screen materials more thoroughly.

[0020] As a preferred embodiment of this utility model, both the connecting plate and the base plate are U-shaped. An extension plate is connected to the side wall of the opening of the base plate. The extension plate is located below the first impurity outlet and the second waste material outlet. The bottom end of the discharge pipe is located inside the feed pipe of the blow molding machine.

[0021] By adopting the above technical solution, the connecting plate and the bottom plate are both U-shaped to avoid interference with the downward movement of the processing cylinder and the discharge pipe. The extension plate is used to place the receiving cylinder, so that the receiving cylinder is placed below the first impurity outlet and the second waste material outlet. The bottom end of the discharge pipe is located inside the feed pipe of the blow molding machine, which can prevent the material from falling outside the feed pipe of the blow molding machine.

[0022] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a first screen plate and a second screen plate. After the material passes through the first screen plate and the second screen plate for filtration, impurities smaller than the material diameter will fall below the first screen plate, achieving the filtration effect for impurities smaller than the material diameter. Impurities larger than the material diameter will fall above the second screen plate and be discharged from the first impurity outlet, thus achieving the filtration effect for impurities larger than the material diameter. The material passes through the second screen plate and falls into the discharge pipe, and then is fed into the feed pipe of the blow molding machine from the discharge pipe, completing the material feeding effect of the blow molding machine. 2. This utility model starts the motor, which drives the cam to rotate. The cam presses and releases the connecting plate in a cycle. The connecting plate presses down on the spring, compressing the spring. At the same time, the connecting plate moves the processing cylinder downward. Then, the cam releases the connecting plate, and the spring pulls the connecting plate up, causing the processing cylinder to move upward, thereby achieving the effect of vibrating the processing cylinder up and down.

The material will be screened by the screening mechanism 4, so that the impurities larger than the material and the impurities smaller than the material can be removed together, improving the material filtration effect. Then, the material falls from the outlet pipe 3 into the feed pipe 9 of the blow molding machine, realizing the effect of material filtration and feeding.

[0028] Please refer to Figure 2 , Figure 3 and Figure 6 The screening mechanism 4 includes a support plate 401, a first screen plate 402, a guide inclined plate 403, a second screen plate 404, and a first impurity outlet 405.

The bottom end of each first screen plate 402 is connected to the top end of the support plate 401. The outer wall of the support plate 401 is connected to the inner wall of the processing cylinder 1. One end of each first screen plate 402 has a gap from one side wall of the processing cylinder 1. The four sides of the second screen plate 404 are respectively connected to the four inner walls of the processing cylinder 1.

The obstruction ramp 8 is used to prevent debris from falling into the connecting pipe 501 located below. The frustum shape of the connecting pipe 501 allows the inlet ends of the connecting pipes 501 on both sides to guide the debris to flow into the same storage box 502, where it is collected.

[0038] Please refer to Figure 1 , Figure 2 and Figure 5 The vibration mechanism 6 includes a base plate 601, guide rods 602, springs 603, connecting plate 604, side plate 605, motor 606, and cam 607. Multiple guide rods 602 are connected to the top of the base plate 601. The guide rods 602 are T-shaped. Springs 603 are connected to the top of the guide rods 602. Connecting plate 604 is connected to the bottom of the springs 603. The side wall of connecting plate 604 is movably connected to the guide rods 602. The side wall of connecting plate 604 is connected to the bottom of the outer side wall of the processing cylinder 1. The bottom of the base plate 601 is connected to the blow molding machine feed pipe 9. Side plate 605 is connected to one side wall of the base plate 601. Motor 606 is connected to the side wall of side plate 605. Cam 607 is connected to the output end of motor 606. The side wall of cam 607 can contact the top of connecting plate 604.

[0039] Start the motor 606, which drives the cam 607 to rotate. The cam 607 presses and releases the connecting plate 604 in a cycle. The connecting plate 604 presses down on the spring 603, compressing the spring 603. At the same time, the connecting plate 604 drives the processing cylinder 1 to move downward. Then, the cam 607 releases the connecting plate 604, and the spring 603 pulls the connecting plate 604 up, causing the processing cylinder 1 to move upward.

[0042] The working principle and usage process of this utility model are as follows: In specific use, the motor 606 is started, which drives the cam 607 to rotate, so that the cam 607 presses and releases the connecting plate 604 in a cycle. The connecting plate 604 presses the spring 603 downward, and the spring 603 is compressed. At the same time, the connecting plate 604 drives the processing cylinder 1 to move downward. Then, the cam 607 releases the connecting plate 604, and the spring 603 will pull the connecting plate 604 upward, so that the processing cylinder 1 moves upward, thereby achieving the effect of vibrating the processing cylinder 1 up and down. When material is fed into inlet pipe 2, it flows along the first screen plate 402. At this time, the movement trajectory of the material is S-shaped. When the material passes through the first screen plate 402, impurities smaller than the material diameter will be screened and fall below the first screen plate 402. Then, the impurities smaller than the material diameter fall into the connecting pipe 501 along the guide inclined plate 403. Using the frustum shape of the connecting pipe 501, the inlet ends of the connecting pipes 501 on both sides can guide the impurities to flow into the same collection box 502 and be collected by the collection box 502. The material then falls from the first screen plate 402 into the second screen plate 404, so that the impurities larger than the material diameter fall above the second screen plate 404 and are discharged from the first impurity outlet 405, thereby achieving the effect of filtering impurities larger than the material diameter.
