DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] The utility model provides a technical solution: Figure 1-4 The utility model discloses a fixing device for processing a plastic barrel, comprising a base 1, on which an adsorption mechanism 2 is provided, the adsorption mechanism 2 comprises an air pump 22, a diverter groove 21 is opened in the base 1, the air pump 22 is fixedly installed in the diverter groove 21, and the exhaust end of the air pump 22 extends to the outside of the base 1 and is fixedly connected to the base 1, a blocking member 23 is provided on the top of the base 1, and a supporting mechanism 3 is provided on the outer peripheral side of the base 1.

[0021] In this embodiment, when the improved plastic barrel processing fixing device is used, the operator directly places the plastic barrel on the base 1, and then starts the air pump 22 to inject the gas in the diverter groove 21 into the plastic barrel through the support mechanism 3, so that a high-pressure chamber is formed in the plastic barrel, and the barrel wall of the plastic barrel is supported by the gas inside the plastic barrel to a certain extent, thereby enhancing the barrel wall strength of the plastic barrel. At the same time, the sealing member 23 cooperates with the air pump 22 to form a plurality of negative pressure chambers at the bottom of the plastic barrel, so that the plastic barrel is adsorbed and fixed on the base 1;

[0022] It should be noted that the base 1 is fixedly mounted on the loading platform of the plastic barrel trimming device or the plastic deburring device by means of bolts.

[0023] In a further preferred embodiment of the present invention, Figure 2 As shown, the blocking member 23 includes a soft pad 231, which is fixedly mounted on the top side of the base 1. The soft pad 231 and the base 1 are both provided with a plurality of circular holes 232, and the plurality of circular holes 232 are arranged in a circular array;

[0024] In this embodiment, the setting of the soft pad 231 allows the top side of the base 1 to adapt and change according to the bottom wall of the plastic barrel it contacts, so that the top side of the base 1 fits tightly with the bottom side of the plastic barrel, thereby blocking the gap between the bottom side of the plastic barrel and the top side of the base 1, and preventing external gas from flowing into the circular hole 232 through the above-mentioned gap.

[0025] In a further preferred embodiment of the present invention, Figure 2 As shown, a first pressure limiting valve 233 is fixedly installed in the circular hole 232, and the top end of each first pressure limiting valve 233 is gap-matched with the soft pad 231, and the bottom end of the first pressure limiting valve 233 is inserted into the diverter groove 21;

[0026] In this embodiment, when the air pump 22 extracts the gas in the diverter groove 21, a negative pressure cavity is continuously formed in the diverter groove 21, and the circular hole 232 on the bottom side of the plastic barrel does not allow external gas to flow into the circular hole 232 due to the obstruction of the plastic barrel, thereby forming a negative pressure cavity in the circular hole 232 on the bottom side of the plastic barrel at the same time, and finally the plastic barrel is automatically adsorbed and fixed on the base 1 through the negative pressure cavity in the circular hole 232 on the bottom side of the plastic barrel;

[0027] After the air pump stops running, due to the obstruction of the pressure limiting valve, the external gas will not continue to flow into the diverter groove 21 through the circular hole 232 on the outer side of the plastic barrel, so that after the air pump 22 stops running, a stable negative pressure cavity can be continuously formed in the diverter groove 21 and the circular hole 232 on the bottom side of the plastic barrel.

[0028] In a further preferred embodiment of the present invention, Figure 3 As shown, the support mechanism 3 includes a piston plate 31, a soft tube 32 is fixedly installed through the center of the piston plate 31, and the air inlet end of the soft tube 32 is connected to the exhaust end of the air pump 22;

[0029] In this embodiment, after the air pump 22 extracts the gas in the diversion groove 21, it can introduce the extracted gas into the plastic barrel through the soft tube 32, and due to the obstruction of the piston plate 31, the gas injected into the plastic barrel is intercepted in the plastic barrel, thereby forming a high-pressure chamber in the plastic barrel, exerting a thrust on the barrel wall of the plastic barrel.

[0030] In a further preferred embodiment of the present invention, Figure 3 As shown, a plurality of second pressure limiting valves 33 are arranged in a circle on the outer circumference of the soft tube 32, and each second pressure limiting valve 33 is fixedly passed through the piston plate 31;

[0031] In this embodiment, as the gas flows into the plastic barrel, the air pressure in the plastic barrel gradually increases, and the pressure difference at both ends of the second pressure limiting valve 33 gradually increases. After the pressure difference at both ends of the second pressure limiting valve 33 exceeds the threshold value, the excess gas in the plastic barrel is discharged from the plastic barrel through the second pressure limiting valve 33, so that the pressure in the plastic barrel will not be too high, causing the thrust on the barrel wall of the plastic barrel to exceed the threshold value, causing the barrel wall of the plastic barrel to expand and deform.

[0032] In a further preferred embodiment of the present invention, Figure 4 As shown, a plurality of flow guide holes 34 are provided in a circumferential array on the outer peripheral wall of the piston plate 31, and the bottom end of each flow guide hole 34 extends to the bottom side of the piston plate 31, a piston rod 35 is provided in the flow guide hole 34, and the outer peripheral wall of the piston rod 35 contacts the inner wall of the corresponding flow guide hole 34, and a soft block 36 is fixedly mounted on the piston rod 35, and the soft block 36 contacts the inner wall of the corresponding flow guide hole 34;

[0033] In this embodiment, during the process of the pressure rising in the above-mentioned plastic barrel, the pressure in the guide hole 34 also gradually rises, and due to the push of the gas on the piston rod 35, the piston rod 35 pushes the soft block 36 to fit tightly with the inner wall of the plastic barrel, and the resistance between the soft block 36 and the inner wall of the plastic barrel gradually increases, so that a huge friction force is generated between the plastic block and the inner wall of the plastic barrel, and the mutual resistance between the piston rod 35 and the inner wall of the guide hole 34 is used to lock the position of the piston plate 31 in the plastic barrel.

[0034] Working principle: When the improved plastic barrel processing fixing device is used, the operator places the plastic barrel on the soft pad 231 on the base 1, and then the operator inserts the piston plate 31 into the plastic barrel, and makes the top side of the piston plate 31 always have a specific distance with the top side of the plastic barrel. At this time, due to the friction between the outer peripheral wall of the piston plate 31 and the inner wall of the plastic barrel, the piston plate 31 is relatively stably located in the opening of the plastic barrel, and then the air pump 22 is started. The air pump 22 continuously extracts the gas in the diversion groove 21 and injects the gas into the plastic barrel through the soft tube 32, so that the air pressure in the plastic barrel gradually increases, and the gas in the guide hole 34 increases synchronously. At this time, due to the push of the piston rod 35 by the gas in the guide hole 34, the piston rod 35 moves toward the inner wall of the plastic barrel, so that the soft block 36 and the inner wall of the plastic barrel are mutually opposed, and then a great friction is generated between the soft block 36 and the inner wall of the plastic barrel, and the mutual opposition between the piston rod 35 and the inner wall of the guide hole 34 is cooperated to lock the position of the piston plate 31 in the plastic barrel;

[0035] As the air pressure in the plastic barrel rises, the pressure difference at both ends of the second pressure limiting valve 33 gradually increases. After the pressure difference at both ends of the second pressure limiting valve 33 exceeds the threshold, the excess gas in the plastic barrel passes through the second pressure limiting valve 33 and flows out of the plastic barrel. At this time, the plastic barrel has a stable air pressure, and the gas can exert a stable thrust on the barrel wall of the plastic barrel. At the same time, whether the air pump 22 is turned off is determined by whether the gas is discharged from the second pressure limiting valve 33.

[0036] As the gas in the diverter groove 21 is lost, the negative pressure strength in the diverter groove 21 continues to increase, and the pressure difference at both ends of the first pressure limiting valve 233 gradually expands. After the pressure difference at both ends of the first pressure limiting valve 233 exceeds the threshold, the gas in the circular hole 232 continues to flow into the diverter groove 21 to replenish the lost gas in the diverter groove 21, and the outside gas continues to flow into the circular hole 232 on the outer peripheral side of the plastic barrel to replenish the lost gas in the circular hole 232. Since the amount of gas flowing from the circular hole 232 into the diverter groove 21 is limited, the diverter groove 21 The negative pressure strength inside gradually tends to be stable, and the circular hole 232 located below the plastic barrel, due to the obstruction of the plastic barrel, the outside gas will not flow into the circular hole 232, so that a negative pressure cavity is formed in the circular hole 232 at the bottom side of the plastic barrel, and the plastic barrel is adsorbed and fixed on the base 1. After the air pump 22 stops running, a stable negative pressure cavity is gradually formed in the diverter groove 21 due to the inflow of outside gas, and the circular hole 232 below the plastic barrel also forms a stable negative pressure cavity due to the lack of outside gas inflow, so that the plastic barrel is stably adsorbed and fixed on the base 1;

[0037] After the plastic barrel is fixed, the wall of the plastic barrel is greatly strengthened due to the push of the internal gas, and it will hardly be deformed due to the contact between the plastic barrel and foreign objects. After the plastic barrel is processed, according to the above, the operator uses the air pump 22 and the soft tube 32 to pump the gas in the plastic barrel into the diverter groove 21, so that the air pressure in the circular hole 232 and the plastic barrel is restored, thereby releasing the locking state of the piston plate 31 and the adsorption force on the plastic barrel. The operator can directly pull the piston plate 31 out of the plastic barrel, and then directly remove the plastic barrel from the base 1;

[0038] It should be noted that a sensor is installed in the circular hole 232 to monitor the flow of gas in the circular hole 232. The position of the plastic barrel on the base 1 can be determined by the flow state of the gas in the circular hole 232, so that the processing device robot arm can adaptively change the processing path according to the position of the plastic barrel on the base 1 without manual adjustment by the operator.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
