Description

Technical Field

[0001] This utility model relates to the field of plastic bucket production technology, and in particular to a rapid cooling and shaping device for plastic buckets. Background Technology

[0002] Plastic buckets are a widely used type of container for storing and transporting agricultural and chemical agents, primarily manufactured using a hollow blow molding process. The molding method involves moving the preform to below a blow pin in a blow molding machine, where the mold begins to close. The blow pin then extends downwards and blows air, causing the preform to form within the mold. While the blow pin is blowing air, cooling pipes within the mold continuously introduce cold air into the bucket to aid in the molding process. However, the cold air can only cool the plastic bucket inside, and the air inlet and outlet are located near the bucket opening, preventing complete circulation. This results in low cooling efficiency and a prolonged cooling time for the plastic buckets. Therefore, a rapid cooling and shaping device for plastic buckets is needed to cool and shape the formed buckets more quickly, thereby increasing production efficiency. Utility Model Content

[0005] Preferably, the fixed water cooling module includes a fixed cooling copper mold, the fixed cooling copper mold has a cooling passage inside, one end of the cooling passage is connected to a water inlet pipe and the other end is connected to a water outlet pipe, and the surface of the fixed cooling copper mold is provided with a positioning model, the positioning model is matched with the bottom end face of the plastic bucket.

[0006] Furthermore, the mobile water-cooling module includes a telescopic cylinder, which is fixedly connected to the frame. A mobile cooling copper mold is fixedly connected to the telescopic head of the telescopic cylinder. A positioning model is provided on the side of the mobile cooling copper mold near the center of the frame. The positioning model corresponds to the shape of the plastic bucket. A cooling passage is also opened inside the mobile cooling copper mold. The two ends of the cooling passage are connected to the inlet pipe and the outlet pipe, respectively.

[0007] Preferably, the air-cooled module includes a rubber stopper, and the rubber stopper is provided with a telescopic air inlet pipe and an air outlet pipe.

[0008] Furthermore, the telescopic air intake pipe includes a connecting hole, in which an exhaust pipe is fixedly connected. One end of the exhaust pipe is closed and the other end is open. A limiting ring is provided on the outer side of the open end of the exhaust pipe. Several air guide holes are also provided on the open end of the exhaust pipe. An air guide pipe is slidably connected between the connecting hole and the exhaust pipe. A retaining ring is fixedly connected to the inner side of one end of the air guide pipe.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention is based on a frame, with a fixed water-cooling module at the bottom of the frame, which is connected to a cooling circulating water system. A movable water-cooling module on the top side of the frame is also connected to a cooling circulating water system. Both the fixed and movable water-cooling modules can fit into contact with the plastic bucket, allowing the bucket's temperature to drop rapidly. Inside the plastic bucket, the air inlet of the air-cooling module, when ventilated, pushes the air guide tube downwards until it is blocked by a limiting ring at the bottom. At this point, the cold air in the air inlet tube can enter the air guide tube through the air inlet and overflow from the bottom of the bucket. The exhaust pipe of the air-cooling module is located at the opening of the plastic bucket, allowing air to be discharged. Thus, cold air enters from the bottom of the bucket and exits from the top, which helps to cool the bucket and improves the shaping efficiency of the plastic bucket. After shaping, reverse air extraction can create negative pressure in the air inlet, causing the guide tube to slide upwards and retract into the air-cooling module. This facilitates the movement of the movable cooling module at the top of the plastic bucket, causing the air-cooling module to detach from the plastic bucket. Attached Figure Description

[0012] The following will describe specific embodiments and appendices. Figure 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0013] A rapid cooling and shaping device for plastic buckets includes a frame 1, which is a cuboid frame. A fixed water-cooling module 2 is fixedly connected to the bottom surface of the frame 1. The fixed water-cooling module 2 includes a fixed cooling copper mold 21. The fixed cooling copper mold 21 is made of copper and has good thermal conductivity, which is beneficial for cooling the plastic bucket when it comes into contact with it. The fixed cooling copper mold 21 has a cooling channel inside, which is distributed in an S-shape throughout the fixed cooling copper mold 21. One end of the cooling channel is connected to a water inlet pipe, and the other end is connected to a water outlet pipe, so that the cooling water can always keep the entire copper mold at a low temperature. When the plastic bucket is placed on the fixed cooling copper mold 21, the fixed cooling copper mold 21 can absorb heat and cool it rapidly. The surface of the fixed cooling copper mold 21 is provided with a first positioning model 22, which fits with the bottom surface of the plastic bucket, so that the plastic bucket can have a larger contact area with the fixed cooling copper mold 21 when it is placed on it, thereby accelerating the cooling speed.

[0014] Mobile water-cooling modules 3 are provided on the left, right, rear and top sides of the frame 1. The mobile water-cooling module 3 includes a telescopic cylinder 31, which is fixedly connected to the frame 1 and faces the center of the frame 1. A mobile cooling copper mold 32 is fixedly connected to the telescopic head of the telescopic cylinder 31. A second positioning model is provided on the side of the mobile cooling copper mold 32 near the center of the frame 1. The second positioning model corresponds to the shape of the plastic bucket. Under the positioning action of the first positioning model 22, many second positioning models can accurately contact the plastic bucket and fit with the corresponding bucket surface, increasing the contact area and facilitating the cooling of the plastic bucket. The mobile cooling copper mold 32 also has a cooling passage inside. The two ends of the cooling passage are connected to the inlet pipe and the outlet pipe, respectively, to introduce cooling water to maintain the low temperature of the mobile cooling copper mold 32 and maintain its efficient cooling function.

[0015] A control switch 11 is also provided. The control switch 11 is existing technology and can be activated by pressing. The control switch 11 is connected to several telescopic cylinders 31. The control switch 11 can control the extension and retraction of the telescopic rod. A water tank is provided at the bottom of the frame 1. A water pump is provided in the water tank. Both the water tank and the water pump are existing technology. The water pump and the telescopic cylinders 31 are connected to the control switch 11. The opening and closing of the control switch 11 can also simultaneously control the water pump to start supplying water to the water inlet pipe, thereby causing the movable water cooling modules 3 on the left, right, rear and top sides of the frame 1 to retract towards the middle, so that the movable cooling copper mold 32 approaches and contacts the plastic bucket for cooling.

[0016] The front side of the frame 1 is provided with an opening and closing door 4, which is rotatably connected to the frame 1. The control switch 11 is fixedly connected to the front side of the frame 1. The frame 1 is provided with a corresponding magnetic door lock 41. When the opening and closing door 4 is rotated to close, it can be attracted by the magnetic door lock 41 to keep it closed. At this time, the opening and closing door 4 presses the control switch 11 to open the control switch 11, thereby controlling the telescopic cylinder 31 and the water pump to work. After the plastic bucket is placed on the fixed module, the opening and closing door 4 rotates to close, which can press the control switch 11 to start the water pump to deliver water. At the same time, the telescopic head of the telescopic cylinder 31 extends forward, thereby cooling the plastic bucket from the outside.

[0017] An air-cooled module 5 is fixedly connected to the movable water-cooled module 3 located at the top of the frame 1. The air-cooled module 5 includes a rubber plug 51, within which are a telescopic air inlet pipe and an air outlet pipe 55. The telescopic air inlet pipe includes a connecting hole 52, which is connected to an air blower. The air blower is existing technology and is also connected to a control switch 11, which controls its opening and closing. An exhaust pipe 53 is fixedly connected to the connecting hole 52. One end of the exhaust pipe 53 is closed (actually, the top is closed, and the bottom is open). A limiting ring 531 is provided on the outer surface of the open end of the exhaust pipe 53. Specifically, a limiting ring 531 is provided at the lower end, and several air guide holes 532 are provided on the open end of the exhaust pipe 53. The air guide holes 532 are located above the limiting ring 531. An air guide pipe 54 is slidably connected between the connecting hole 52 and the exhaust pipe 53. A retaining ring 541 is fixedly connected to the inner side of one end of the air guide pipe 54. After the plastic bucket is placed on the fixed water-cooling module 2, the opening and closing door 4 is closed, and the control switch 11 is triggered to move the movable water-cooling module 3 toward the plastic bucket, so that the rubber stopper 51 is aligned and inserted into the plastic bucket. The barrel opening has a telescopic air inlet pipe that blows air in, while the outlet pipe 55 connects to the outside and exhausts air outwards, thus cooling the inner wall of the barrel with cold air. Initially, the air guide pipe 54 is located at the upper part between the exhaust pipe 53 and the connecting hole 52. At this time, the retaining ring 541 fills the gap between the connecting hole 52 and the exhaust pipe 53, preventing the cold air from escaping normally. As the air pressure increases, the pressure will push the air guide pipe 54 downwards, causing the retaining ring 541 to move downwards until it is obstructed by the limiting ring 531. At this point, the connecting hole 52... The space between the exhaust pipe 53 and the vent pipe 54 is connected to the inside of the bucket through the air guide hole 532. The air guide pipe 54 slides so that its lower end is located at the bottom of the bucket. The cold air discharged from the exhaust pipe 53 will be discharged directly into the bottom of the bucket along the air guide pipe 54. Subsequently, as more cold air is discharged, the upper air will be discharged from the vent pipe 55 under pressure. This allows the cold air to enter the bottom of the plastic bucket and be discharged from the exhaust hole at the top of the plastic bucket from bottom to top. This allows the cold air to fully contact the inner wall of the plastic bucket, thereby achieving efficient cooling of the inner wall of the bucket.

[0018] After the shape is set, reverse air extraction can be used to create negative pressure in the air inlet, which will cause the guide tube to slide upward and retract into the air-cooling module 5, making it easier for the mobile cooling module located at the top of the plastic bucket to move and drive the air-cooling module 5 to detach from the plastic bucket.
