Technical Field

[0001] This utility model relates to the field of epoxy resin processing technology, and in particular to an epoxy resin curing agent dilution device. Background Technology

[0002] When diluting epoxy resin curing agents, it is necessary to control the dilution ratio. Chinese Patent Application No. 202321501912.8 discloses an epoxy resin curing agent dilution device, including a dilution component, a feeding component, and a stirring component. The dilution component includes a dilution tank with a drain pipe at its lower end and a first drain valve installed outside the drain pipe. The feeding component includes a storage tank with an inlet pipe at its upper end, a plug threaded onto the inlet pipe, and a metering tank connected to the storage tank via a guide pipe. A feeding pipe is located at the lower end of the metering tank, and a second drain valve is installed outside the feeding pipe. The stirring component includes a motor fixed to the upper end of the dilution tank. The motor's output end is connected to a drive shaft, which is connected to a stirring shaft via a drive belt. The stirring shaft is hollow, with its upper end movably sleeved outside the feeding pipe via a bearing, and its lower end rotatably positioned inside the dilution tank.

[0003] While the above-mentioned technology dilutes and adds liquid by opening liquid outlet holes inside the stirring shaft and stirring rod, in actual use, material is easily left inside the stirring shaft and stirring rod during discharge and cannot be completely discharged. Moreover, the equipment is not easy to clean due to its small internal space, which makes the equipment inconvenient to use. Therefore, in order to solve the above-mentioned technical defects, we propose an epoxy resin curing agent dilution device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an epoxy resin curing agent dilution device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An epoxy resin curing agent dilution device includes a mixing tank. The mixing tank has a top cover at its upper end. A linkage cylinder is rotatably mounted in the middle of the top cover. Several stirring rods are mounted on the outer wall of the linkage cylinder inside the mixing tank. A protective cover is installed on the outer surface of the top cover. A drive assembly is provided inside the protective cover and between it and the linkage cylinder. A telescopic component is installed at the upper end of the protective cover. A matching push rod is installed at the output end of the telescopic component corresponding to the inner diameter of the linkage cylinder. A linkage pipe is slidably mounted on one side of the protective cover through a dustproof component. An elbow is provided at one end of the linkage pipe inside the protective cover, with the output end of the elbow facing the inside of the linkage pipe. A bracket is provided on the upper side of the top cover. A reset component is provided between the bracket and the linkage pipe.

[0007] Preferably, the upper end of the bracket is fixed with a guide seat, a limit block is slidably provided inside the guide seat, the linkage tube passes through the limit block, and the two ends of the reset member are respectively connected to the limit block and the bracket.

[0008] Preferably, the end of the limiting block away from the push rod is provided with a positioning block, and the limiting block is strip-shaped.

[0009] Preferably, the dustproof component includes an installation cylinder and a wiping sleeve. The installation cylinder is installed on the wall of the protective cover, the wiping sleeve is installed inside the installation cylinder, and the linkage tube slides through the inside of the wiping sleeve.

[0010] Preferably, the elbow of the linkage pipe is arc-shaped, and a number of ball bearings are provided on the side of the elbow facing the push rod.

[0011] Preferably, the lower end of the push rod is tapered with rounded corners at the end, and a sealing ring is provided at the lower end of the outer ring surface of the push rod.

[0012] Preferably, the drive assembly includes a motor, a pulley, and a belt. The motor is installed inside the protective cover, the pulley is installed on the outer ring surface of the linkage cylinder and the output end of the motor, and the belt is sleeved on the outside of the pulley.

[0013] The epoxy resin curing agent dilution device proposed in this utility model has the following advantages:

[0014] 1. In this utility model, the linkage pipe, linkage cylinder, and push rod are set in a separate manner, so that the stirring rod can continue to operate when the diluent is added, which is convenient for stirring. When discharging material and after the diluent is added, the push rod can be moved down to return the material inside the linkage cylinder to the stirring tank. This solves the problem of material residue inside the stirring component in the traditional solution, which makes it impossible to completely discharge the material and is not conducive to subsequent cleaning. In addition, the push rod can be moved up and down to draw the material inside the stirring tank into or out of the linkage cylinder, thereby further improving the stirring efficiency of the material inside the stirring tank.

[0015] 2. The guide seat and limiting block in this utility model ensure that when the linkage tube moves horizontally, its two ends are restricted by the protective cover and the bracket, respectively, thus effectively ensuring the stability of the linkage tube during movement and preventing rotation. This also ensures that the elbow at the end of the linkage tube always faces downward. The positioning block facilitates the limiting and positioning of the linkage tube, ensuring that the elbow aligns with the inside of the linkage cylinder after the linkage tube is reset. The dustproof component ensures that when the linkage tube moves horizontally, the gap between the outer ring surface of the linkage tube and the protective cover is filled with an elastic cotton wiping sleeve, thereby preventing external dust from entering the interior of the protective cover from the gap between the two.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1

[0023] Reference Figure 1-4 An epoxy resin curing agent dilution device includes a mixing tank 1, a top cover 2 at the upper end of the mixing tank 1, a linkage cylinder 3 rotatably mounted in the middle of the top cover 2, a plurality of stirring rods 4 on the outer wall of the linkage cylinder 3 located inside the mixing tank 1, a protective cover 5 mounted on the outer surface of the top cover 2, a drive assembly being provided between the protective cover 5 and the linkage cylinder 3, a telescopic component 6 mounted on the upper end of the protective cover 5, a matching push rod 7 mounted on the output end of the telescopic component 6 corresponding to the inner diameter of the linkage cylinder 3, a linkage pipe 8 slidably mounted on one side of the protective cover 5 through a dustproof component, a bend being provided at one end of the linkage pipe 8 located inside the protective cover 5 with the output end of the bend facing the inside of the linkage pipe 8, a bracket being provided on the upper side of the top cover 2, and a reset component 9 being provided between the bracket and the linkage pipe 8.

[0024] Example 2

[0025] Reference Figure 1-4 While all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0026] A guide seat 10 is fixed to the upper end of the bracket. A limiting block 11 is slidably provided inside the guide seat 10. The linkage tube 8 passes through the limiting block 11. The two ends of the reset member 9 are connected to the limiting block 11 and the bracket, respectively. A positioning block 12 is provided at the end of the limiting block 11 away from the push rod 7. The limiting block 11 is strip-shaped. The arrangement of the guide seat 10 and the limiting block 11 ensures that when the linkage tube 8 moves horizontally, its two ends are restricted by the protective cover 5 and the bracket, respectively. This effectively ensures the stability of the linkage tube 8 during movement and also prevents the linkage tube 8 from rotating during movement, thus facilitating the movement of the ends of the linkage tube 8. The elbow can always face downwards, and the positioning block 12 facilitates the limiting and positioning of the linkage pipe 8, ensuring that the elbow of the linkage pipe 8 is aligned with the inner side of the linkage cylinder 3 after reset. The dustproof component includes an installation cylinder and a wiping sleeve 13. The installation cylinder is installed on the wall of the protective cover 5, and the wiping sleeve 13 is installed inside the installation cylinder. The linkage pipe 8 slides through the inner side of the wiping sleeve 13. The dustproof component ensures that when the linkage pipe 8 moves horizontally, the gap between the outer ring surface of the linkage pipe 8 and the protective cover 5 is filled by the elastic cotton wiping sleeve 13, thereby preventing external dust from entering the interior of the protective cover 5 from the gap between the two.

[0027] The elbow of the linkage pipe 8 is arc-shaped, and several ball bearings 14 are provided on the side of the elbow facing the push rod 7. The ball bearings 14 make it easier to push the push rod 7 when it comes into contact with the elbow, thus avoiding interference from the elbow at the end of the linkage pipe 8 on the movement of the push rod 7. The lower end of the push rod 7 is tapered with rounded corners. A sealing ring is provided at the lower end of the outer ring surface of the push rod 7. The sealing ring facilitates the scraping of residual material on the inner wall of the linkage cylinder 3 when the push rod 7 moves down, and the rounded corners at the lower end facilitate better pushing of the elbow at the end of the linkage pipe 8 by the push rod 7. The drive assembly includes a motor 15, a pulley 16, and a belt 17. The motor 15 is installed inside the protective cover 5, the pulley 16 is installed on the outer ring surface of the linkage cylinder 3 and the output end of the motor 15, and the belt 17 is sleeved on the outside of the pulley 16. The drive assembly facilitates the rotation of the linkage cylinder 3, thereby facilitating the stirring of the material inside the mixing tank 1.

[0028] Operating principle and advantages: During use, the epoxy resin curing agent material from the outside enters through the feed pipe on the side of the mixing tank 1, while the external liquid for dilution is connected to the linkage pipe 8 through an external feeding facility. When the drive assembly rotates the linkage cylinder 3, the lower end of the linkage cylinder 3 drives the stirring rod 4 to stir the material inside the mixing tank 1. Simultaneously, when dilution liquid needs to be added, the push rod 7 is moved upwards via the telescopic component 6 until it disengages from the elbow at the end of the linkage pipe 8. At this point, the reset component 9... The lower linkage pipe 8 drives the elbow to move towards the linkage cylinder 3 until the elbow is finally aligned with the inside of the linkage cylinder 3. At this time, the external dilution liquid supply facility supplies dilution liquid into the linkage cylinder 3 through the linkage pipe 8. After the dilution liquid supply is completed, the push rod 7 is pushed down by the telescopic component 6. When the push rod 7 moves down, it squeezes the elbow, causing the linkage pipe 8 to move horizontally and away from the push rod 7. Then the push rod 7 enters the interior of the linkage cylinder 3. As the push rod 7 moves down, the material inside the linkage cylinder 3 is pushed downward and finally flows back into the mixing tank 1.

[0029] In summary, this solution, through the separate configuration of the linkage pipe 8, linkage cylinder 3, and push rod 7, allows the stirring rod 4 to continue operating while the diluent is being added, facilitating stirring. During discharge and after the diluent is added, the downward movement of the push rod 7 can return the material inside the linkage cylinder 3 to the mixing tank 1. This solves the problem of material residue remaining inside the stirring components in traditional solutions, which prevents complete discharge and hinders subsequent cleaning. Furthermore, the push rod 7 can be controlled to move up and down, thereby drawing material from or pushing it out of the linkage cylinder 3, further improving the stirring efficiency of the material inside the mixing tank 1.

[0030] It should be further explained that the guide seat 10 and the limiting block 11 ensure that when the linkage pipe 8 moves horizontally, its two ends are restricted by the protective cover 5 and the bracket, respectively, thus effectively ensuring the stability of the linkage pipe 8 during movement and preventing rotation. This also ensures that the elbow at the end of the linkage pipe 8 always faces downwards. The positioning block 12 facilitates the limiting and positioning of the linkage pipe 8, ensuring that the elbow of the linkage pipe 8 is aligned with the inner side of the linkage cylinder 3 after reset. The dustproof component ensures that when the linkage pipe 8 moves horizontally, the outer ring surface of the linkage pipe 8 is kept within the protective cover 5. The gap between the two is filled with an elastic cotton wiping sleeve 13, thus preventing external dust from entering the protective cover 5 through the gap between them; the setting of the ball bearing 14 makes it easier to push the push rod 7 when it comes into contact with the elbow, thus avoiding the phenomenon that the elbow at the end of the linkage pipe 8 interferes with the movement of the push rod 7; the setting of the sealing ring makes it easy to scrape off the material remaining on the inner wall of the linkage cylinder 3 when the push rod 7 moves down, and the setting of its lower end rounded corner makes it easier for the push rod 7 to push the elbow at the end of the linkage pipe 8 better; the setting of the drive component makes it easy to drive the linkage cylinder 3 to rotate, thereby facilitating the stirring of the material inside the mixing tank 1.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
