Technical Field
[0001] This utility model relates to the technical field of spiral energy-saving air ring cooling device for film blow molding machines, and in particular to a spiral energy-saving air ring cooling device for film blow molding machines. Background Technology
[0002] The spiral energy-saving air ring cooling device is a device for cooling high-temperature objects. When cooling the plastic blown by a film blow molding machine, the air ring is placed on the surface of the blow molding machine to cool the blown plastic.
[0003] The inventors discovered during daily use of the spiral energy-saving air ring cooling device that the cold air blown out of the air outlet of a typical air ring has a fixed flow rate. This results in excess gas being wasted when cooling the later part of the air ring, thus preventing the air ring from saving energy and causing problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a spiral energy-saving air ring cooling device for film blow molding machines.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spiral energy-saving air ring cooling device for a film blow molding machine, comprising an air ring, an air inlet pipe fixedly connected to the side of the air ring, an air nozzle fixedly connected to the surface of the air ring, a connecting pipe fixedly connected to the side of the air ring, an energy-saving device provided on the surface of the air ring, the energy-saving device comprising a ring disposed on the surface of the air ring, a connecting rod fixedly connected to the surface of the ring, a baffle fixedly connected to one end of the connecting rod, a groove formed on the surface of the air nozzle, and a baffle slidably connected inside the groove.
[0006] The effects achieved by the above components are as follows: under the action of the baffle, when the plastic is cooled to the later stage, the airflow of the air nozzle can be reduced, thereby achieving energy saving. When it is necessary to cool the plastic film, the air ring is moved to the nozzle of the film blow molding machine. After the plastic film is blown out, the fan is connected to the air inlet pipe and started, so that the air ring is filled with gas and sprayed out from the air nozzle, thereby cooling the plastic film. Under the action of the energy-saving device, the air ring saves energy.
[0007] Preferably, a rubber ring is fixedly connected to the surface of the baffle, and the rubber ring is evenly arranged on the surface of the baffle.
[0008] The effect achieved by the above components is that, under the action of the rubber ring, the air inside the nozzle will not leak out from between the groove and the baffle, thus achieving a sealing effect.
[0009] Preferably, the surface of the air ring is provided with a groove, and a locking block is slidably connected inside the groove, with the ring fixed to the surface of the locking block.
[0010] The effect achieved by the above components is that, under the action of the slot and the block, the ring will not be removed from the surface of the air ring, thus avoiding separation.
[0011] Preferably, a rectangular plate is fixedly connected to the side of the card block, and a card rod is clinically tested on the surface of the rectangular plate. A circular groove is formed on the inner wall of the card slot, and a card rod is inserted into the inside of the circular groove.
[0012] The aforementioned components achieve the following effects: Under the action of the locking rod and the circular groove, the baffle can be fixed after moving to the appropriate position. When the plastic film cools down to the point where energy saving of the air ring is required, the locking block is rotated, causing it to rotate inside the locking groove, which in turn drives the circular ring to rotate. This allows the baffle to be inserted into the air inlet nozzle. Under the action of the rubber ring, the air inside the air inlet nozzle will not leak out from between the groove and the baffle, thus achieving a sealing effect. This reduces the air volume output of the air inlet nozzle. After the baffle moves to the appropriate position, it can be fixed under the action of the locking rod and the circular groove, thus achieving energy saving.
[0013] Preferably, the surface of the connecting tube is provided with a splicing device, the splicing device includes a hollow rod fixedly connected to the surface of the connecting tube, and a groove is opened inside the other connecting tube, and a retaining ring is fixedly connected to the surface of the hollow rod.
[0014] The effect achieved by the above components is that, under the action of the retaining ring and the hollow rod, the connecting pipes can be spliced together, and at the same time, they can be locked together.
[0015] Preferably, a washer made of rubber is fixedly connected to one end of the hollow rod.
[0016] The effect achieved by the above components is that, under the action of the washer, the hollow rod will not directly impact the inner wall of the groove, thus avoiding deformation and damage to the hollow rod.
[0017] Preferably, a locking rod is inserted into the surface of the connecting tube, and the locking rod is inserted into the interior of the hollow rod.
[0018] The effect achieved by the above components is that, under the action of the locking rod, the hollow rod can be fixed inside the connecting tube, thereby achieving the function of fixation.
[0019] Preferably, a spring is sleeved on the surface of the locking rod, and the two ends of the spring are respectively fixedly connected to the surface of the connecting tube at one end of the locking rod.
[0020] The aforementioned components achieve the following effects: Under the action of the spring, the locking rod is self-locking and inserted into the hollow rod, thus achieving a fixing function. When the air rings need to be spliced together, the locking rod is pulled outward, and the hollow rod is inserted into the groove inside the connecting tube. Under the action of the retaining ring and the hollow rod, the connecting tubes can be spliced together and also achieve a locking function. Under the action of the washer, the hollow rod will not directly impact the inner wall of the groove, avoiding deformation and damage to the hollow rod. When the washer contacts the inner wall of the groove, the force pulling the locking rod is released, allowing the locking rod to reset under the action of the spring's own elastic potential energy, and then insert into the hollow rod, thus achieving the splicing function.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting up an energy-saving device, when the plastic film cools to the later stage and energy saving of the air ring is required, the locking block is rotated, causing the locking block to rotate inside the locking groove, thereby driving the ring to rotate. This allows the baffle to be inserted into the air inlet. Under the action of the rubber ring, the air inside the air inlet will not leak out from between the groove and the baffle, thus achieving a sealing effect. This reduces the air volume of the air inlet. When the baffle moves to the appropriate position, under the action of the locking rod and the circular groove, the baffle can be fixed in the appropriate position, thus achieving energy saving and solving the problem of wasted gas blown out by the air ring in the later stage of plastic cooling.

An energy-saving device 2 is provided on the surface of the air ring 1. When it is necessary to cool the plastic film, the air ring 1 is moved to the nozzle of the film blow molding machine. After the plastic film is blown out, the fan is connected to the air inlet pipe 4 and started, so that the inside of the air ring 1 is filled with gas and sprayed out from the air nozzle, thereby cooling the plastic film. Under the action of the energy-saving device 2, the air ring 1 saves energy.
[0029] Reference Figures 2-3The energy-saving device 2 includes a ring 26 disposed on the surface of the air ring 1. A connecting rod 23 is fixedly connected to the surface of the ring 26, and a baffle 24 is fixedly connected to one end of the connecting rod 23. A groove is formed on the surface of the air nozzle, and the baffle 24 is slidably connected inside the groove. Under the action of the baffle 24, the airflow of the air nozzle can be reduced when the plastic is cooled to a certain extent, thereby achieving the effect of energy saving. When it is necessary to cool the plastic film, the air ring 1 is moved to the nozzle of the film blow molding machine. After the plastic film is blown out, the fan and the inlet... The air ducts 4 are connected and activated, causing the air ring 1 to fill with gas and be ejected from the nozzle, thereby cooling the plastic film. Under the action of the energy-saving device 2, the air ring 1 is energy-efficient. Rubber rings 25 are fixedly connected to the surface of the baffle 24, and the rubber rings 25 are evenly arranged on the surface of the baffle 24. Under the action of the rubber rings 25, the air inside the nozzle will not leak out from between the groove and the baffle 24, thus achieving a sealing effect. A slot 22 is formed on the surface of the air ring 1, and a clip is slidably connected inside the slot 22. Block 21 and ring 26 are fixed to the surface of block 21. Under the action of the slot 22 and block 21, ring 26 will not be removed from the surface of air ring 1, avoiding separation. A rectangular plate is fixedly connected to the side of block 21. The surface of the rectangular plate is fitted with a locking rod 27. A circular groove 28 is opened on the inner wall of the slot 22. The locking rod 27 is inserted into the circular groove 28. Under the action of the locking rod 27 and the circular groove 28, the baffle 24 can be moved to the appropriate position and fixed. When the plastic film cools down, the air ring 1 needs to be... When saving energy, rotating the locking block 21 causes it to rotate inside the locking groove 22, which in turn drives the ring 26 to rotate. This causes the baffle 24 to be inserted into the air inlet. Under the action of the rubber ring 25, the air inside the air inlet will not leak out from between the groove and the baffle 24, thus achieving a sealing effect. This reduces the air volume of the air inlet. When the baffle 24 moves to the appropriate position, under the action of the locking rod 27 and the circular groove 28, the baffle 24 can be fixed after moving to the appropriate position, thus achieving the energy-saving effect.
[0030] Reference Figure 4A splicing device 3 is provided on the surface of the connecting pipe 5. The splicing device 3 includes a hollow rod 31 fixedly connected to the surface of the connecting pipe 5. A groove is opened inside the connecting pipe 5. A retaining ring 32 is fixedly connected to the surface of the hollow rod 31. Under the action of the retaining ring 32 and the hollow rod 31, the connecting pipes 5 can be spliced together and can also achieve the function of locking together. A washer 33 is fixedly connected to one end of the hollow rod 31. The washer 33 is made of rubber. Under the action of the washer 33, the hollow rod 31 will not directly hit the inner wall of the groove, avoiding the deformation and damage of the hollow rod 31. A locking rod 34 is inserted into the surface of the connecting pipe 5. The locking rod 34 is inserted into the interior of the hollow rod 31. Under the action of the locking rod 34, the hollow rod 31 can be fixed inside the connecting pipe 5, thereby achieving the function of fixing. A spring 35 is sleeved on the surface of the locking rod 34. One end of the locking rod 34 is fixedly connected to the surface of the connecting tube 5. Under the action of the spring 35, the locking rod 34 is inserted into the hollow rod 31 in a self-locking manner, thereby achieving the fixing function. When it is necessary to splice the air ring 1 together, the locking rod 34 is pulled outward and the hollow rod 31 is inserted into the groove opened inside the connecting tube 5. Under the action of the retaining ring 32 and the hollow rod 31, the connecting tube 5 can be spliced together and can also achieve the locking function. Under the action of the washer 33, the hollow rod 31 will not directly hit the inner wall of the groove, avoiding the deformation and damage of the hollow rod 31. When the washer 33 contacts the inner wall of the groove, the force of pulling the locking rod 34 is released, and the locking rod 34 is reset under the action of the elastic potential energy of the spring 35, and then inserted into the hollow rod 31, thereby achieving the splicing function.
[0031] Working principle: When using the spiral energy-saving air ring 1 cooling device for a film blow molding machine, to cool the plastic film, the air ring 1 is moved to the nozzle of the film blow molding machine. After the plastic film is blown out, the fan is connected to the air inlet pipe 4 and started, causing the air ring 1 to fill with gas and be ejected from the nozzle, thus cooling the plastic film. Under the action of the energy-saving device 2, the air ring 1 is energy-saving. When the plastic film is cooled to the later stage and the air ring 1 needs to be energy-saving again, the locking block 21 is rotated, causing the locking block 21 to rotate inside the locking groove 22, which in turn drives the ring 26 to rotate, so that the baffle 24 is inserted into the air inlet nozzle. Under the action of the rubber ring 25, the air inside the nozzle will not leak out from the groove and the baffle 24, thus achieving a sealing effect, thereby reducing the air volume of the nozzle. After the plate 24 is moved to the appropriate position, under the action of the locking rod 27 and the circular groove 28, the baffle 24 can be fixed after moving to the appropriate position, thereby achieving the energy-saving effect. When it is necessary to splice the wind ring 1 together, the locking rod 34 is pulled outward, and the hollow rod 31 is inserted into the groove opened inside the connecting pipe 5. Under the action of the locking ring 32 and the hollow rod 31, the connecting pipe 5 can be spliced together, and at the same time, it can also achieve the function of locking together. Under the action of the washer 33, the hollow rod 31 will not directly hit the inner wall of the groove, avoiding the phenomenon of deformation and damage of the hollow rod 31. When the washer 33 contacts the inner wall of the groove, the force of pulling the locking rod 34 is released, so that the locking rod 34 is reset under the action of the elastic potential energy of the spring 35, and then inserted into the interior of the hollow rod 31, thereby achieving the splicing function.
