Description

Technical Field

[0001] This utility model belongs to the field of adhesive testing technology, and specifically relates to an adhesive stirring and curing test device. Background Technology

[0002] Adhesive curing tests are a series of tests that evaluate the process of an adhesive (glue) transforming from a liquid or semi-liquid state to a solid state and its final performance. The purpose is to ensure that the adhesive's bonding strength, durability, stability, and other properties meet requirements in practical applications.

[0003] Currently, Chinese utility model patent CN220238304U discloses an adhesive mixing device. Existing adhesive immobilization tests cannot measure the weight and mixing ratio of multiple adhesives, nor can they measure the curing time of different states as needed. Furthermore, during adhesive mixing, adhesive residue remains on the mixing rod, which gradually hardens over time, affecting the normal use of the mixing rod and necessitating frequent replacement. Additionally, after the adhesive cup is placed at the bottom of the mixing rod, its position is prone to shifting, preventing it from being fixed in the center of the mixing rod. This makes it difficult to mix the adhesive around the center of the cup when the mixing rod rotates, thus affecting the uniformity of the adhesive mixing. Utility Model Content

[0004] The purpose of this invention is to provide an adhesive mixing and curing test device, which has the advantages of being able to measure the weight and mixing ratio of multiple adhesives, measure the curing time of different curing states as needed, and facilitate the separation of the mixing rod from the cured adhesive without the rod getting sticky with adhesive.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a glue mixing and curing test device, comprising a fixed upright plate, a large flat plate welded to the bottom of the fixed upright plate, a stirring motor lifting cylinder and a glue cup lifting cylinder respectively provided on the top and bottom of one side of the fixed upright plate, a fixed bracket bolted to the side of the fixed upright plate near the stirring motor lifting cylinder and the glue cup lifting cylinder, a motor mounting bracket and a glue cup lower bracket provided at the output end of the stirring motor lifting cylinder and the glue cup lifting cylinder, which are slidably connected through the fixed upright plate, a stirring motor bolted to the top of the motor mounting bracket on the side of the fixed upright plate away from the stirring motor lifting cylinder, a glue cup provided at the top of the glue cup lower bracket, and a rotating stirring head used in conjunction with the glue cup provided at the output end of the stirring motor.

[0006] The above technical solution involves mixing the resin and hardener in a specific ratio and pouring the mixture into a glue cup. The stirring motor's lifting cylinder and the glue cup's lifting cylinder then move the motor mounting bracket and the lower support of the glue cup closer together, allowing the rotating stirring head to penetrate the glue cup and stir until it gradually hardens. The curing time is then recorded. This allows for the measurement of the weight and mixing ratio of multiple adhesives and, as needed, the measurement of different curing times, improving practicality. A plastic stirring sleeve is fitted over the rotating stirring head. After the rotating stirring head penetrates the glue cup and stirs the mixture until it hardens, the rotating stirring head can be directly pulled out from inside the plastic stirring sleeve. Since the mixture hardens, the plastic stirring sleeve remains inside the glue cup, facilitating separation. A clamping plate, using a spring, holds the bottom of the glue cup, allowing various cup sizes to be clamped and fixed to the top of the lower support. This not only improves placement stability but also centers the glue cup at the top center of the lower support, preventing the rotating stirring head from shifting.

[0007] The present invention is further configured such that the lower support of the glue cup has a glue cup placement groove inside, which is used in conjunction with the glue cup. Each of the four corners of the glue cup placement groove is bolted with a telescopic rod. Each of the four telescopic rods is bolted with a clamp plate that is slidably connected to the lower support of the glue cup at one end. The surface of the telescopic rod is fitted with a spring that is respectively engaged with the clamp plate and the lower support of the glue cup. An upper fixing plate for the glue cup is provided between the motor mounting bracket and the lower support of the glue cup and is bolted to the fixing plate.

[0008] The above technical solution not only improves placement stability but also centers the glue cup at the top center of the lower support, preventing the stirring head from shifting position.

[0009] The present invention is further configured such that an adjusting plate is provided on the side of the fixed upright plate away from the lifting cylinder of the glue cup, which is bolted to the top of the large plate. A weighing scale is bolted to the top of the adjusting plate, and the top of the weighing scale is bolted to the bottom of the lower bracket of the glue cup.

[0010] The above technical solution involves weighing the cups using a weighing scale to calculate the ratio based on the weight ratio of the materials in the two cups.

[0011] The present invention is further configured such that the output end of the stirring motor is bolted with a connecting flange, the top of the rotating stirring head is snapped into one side inside the connecting flange, and a plastic stirring sleeve is slidably sleeved on the surface of the rotating stirring head, and the surface of the plastic stirring sleeve is provided with a groove.

[0012] The above technical solution involves positioning the rotary stirring head at a position offset from the center of the connecting flange from the output shaft of the stirring motor. This allows the rotary stirring head to rotate around the output shaft of the stirring motor after it is turned on.

[0013] The present invention is further configured such that the output ends of the stirring motor lifting cylinder and the glue injection cup lifting cylinder are both snapped with cylinder fixing parts bolted to the fixed upright plate, and air pipe joints are fixedly connected to the sides of the stirring motor lifting cylinder and the glue injection cup lifting cylinder that are far apart from each other.

[0014] The above technical solution involves bolting the lifting cylinder of the mixing motor and the lifting cylinder of the glue injection cup to one side of the fixed plate using cylinder fixing parts.

[0015] The present invention is further configured such that the output ends of the stirring motor lifting cylinder and the glue cup lifting cylinder are both bolted with floating joints, and the ends of the two floating joints that are close to each other are each bolted with a bracket sliding plate. The two bracket sliding plates are respectively bolted to the motor mounting bracket and the end of the glue cup lower bracket that is close to the stirring motor lifting cylinder and the glue cup lifting cylinder.

[0016] The above technical solution is adopted: the lifting cylinder of the stirring motor and the lifting cylinder of the glue cup drive the floating joint and the sliding plate of the bracket to move, so that the sliding plate of the bracket can drive the motor mounting bracket and the lower bracket of the glue cup to slide up and down on the other side of the fixed plate respectively.

[0017] The present invention is further configured such that a guide rail is bolted to the side of the fixed upright plate near the lifting cylinder of the stirring motor and the lifting cylinder of the glue injection cup, and sliders bolted to the sliding plate of the bracket are slidably connected to both sides of the top and bottom of the guide rail.

[0018] The above technical solution is used to limit the vertical sliding of the motor mounting bracket and the lower support of the rubber cup, thereby improving sliding stability.

[0019] In summary, this utility model has the following beneficial effects: 1. After mixing the resin and hardener in the correct proportions, pour the mixture into the glue cup. The stirring motor's lifting cylinder and the glue cup's lifting cylinder then move the motor mounting bracket and the lower support of the glue cup closer together, allowing the rotating stirring head to penetrate the glue cup and stir until it gradually hardens. Record the curing time. This allows for the measurement of the weight and mixing ratio of multiple adhesives and, as needed, the measurement of different curing times, improving practicality. 2. By attaching a plastic mixing sleeve to the surface of the rotary mixing head, when the rotary mixing head is inserted into the glue cup to mix the glue until it solidifies, the rotary mixing head can be directly pulled out from the inside of the plastic mixing sleeve. Since the glue has solidified, the plastic mixing sleeve cannot be pulled out and thus remains inside the glue cup, making it easy to separate. 3. By using a clamp and spring to hold the cups against the bottom surface of the cups, various cup sizes can be clamped and fixed to the top of the cup holder. This not only improves placement stability but also centers the cups at the top of the cup holder, preventing the rotating stirring head from shifting. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example 1: refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5A glue mixing and curing test device includes a fixed plate 1, a large plate 2 welded to the bottom of the fixed plate 1, a stirring motor lifting cylinder 3 and a glue cup lifting cylinder 4 respectively installed at the top and bottom of one side of the fixed plate 1, a fixed bracket 25 bolted to the side of the fixed plate 1 near the stirring motor lifting cylinder 3 and the glue cup lifting cylinder 4, a motor mounting bracket 5 and a glue cup lower bracket 6 slidably connected through the fixed plate 1 at the output end of the stirring motor lifting cylinder 3 and the glue cup lifting cylinder 4, a stirring motor 7 bolted to the top of the motor mounting bracket 5 at the side of the fixed plate 1 away from the stirring motor lifting cylinder 3, a glue cup 12 installed at the top of the glue cup lower bracket 6, and a rotating stirring head 8 for use with the glue cup 12 installed at the output end of the stirring motor 7. After the resin and hardener are mixed in the correct proportions and poured into the glue cup 12, the stirring motor lifting cylinder 3 and the glue cup lifting cylinder 4 drive the motor mounting bracket 5 and the lower support 6 of the glue cup to move closer together. This allows the rotating stirring head 8 to be inserted into the glue cup 12 for stirring until it gradually hardens, and the curing time is recorded. This allows for the measurement of the weight and mixing ratio of multiple adhesives and the measurement of different curing times as needed, improving practicality. By attaching a plastic stirring sleeve 9 to the surface of the rotating stirring head 8, after the rotating stirring head 8 is inserted into the glue cup 12 and the mixed adhesive is stirred until it hardens, the rotating stirring head 8 can be directly pulled out from inside the plastic stirring sleeve 9. Since the mixed adhesive is hardened, the plastic stirring sleeve 9 cannot be pulled out and remains inside the glue cup 12, facilitating separation. A clamping plate 17, with spring 16 pressing against the bottom surface of the glue cup 12, can clamp and fix various cup sizes to the top of the lower support 6. This not only improves placement stability but also centers the glue cup 12 at the top center of the lower support 6, preventing the rotating stirring head 8 from shifting its stirring position.

[0024] refer to Figure 1 , Figure 8 The lower support bracket 6 has a cup placement slot 14 inside, which is used in conjunction with the cup 12. Telescopic rods 15 are bolted to the four corners of the cup placement slot 14. Each of the four telescopic rods 15 has a clamping plate 17 that slides through the lower support bracket 6 at one end. Springs 16 are fitted onto the surface of the telescopic rods 15, respectively engaging with the clamping plate 17 and the lower support bracket 6. A cup-fixing plate 13, bolted to the fixed upright plate 1, is provided between the motor mounting bracket 5 and the lower support bracket 6. This not only improves placement stability but also centers the cup 12 at the top center of the lower support bracket 6, preventing the rotating stirring head 8 from shifting its stirring position.

[0025] refer to Figure 1 , Figure 3 , Figure 5A fixed plate 1 is located on the side of the fixed plate 1 away from the lifting cylinder 4 of the glue cup. An adjusting plate 10 is bolted to the top of the large plate 2. A weighing scale 11 is bolted to the top of the adjusting plate 10. The top of the weighing scale 11 is bolted to the bottom of the lower support 6 of the glue cup. The cup is weighed by the weighing scale 11 to calculate the ratio based on the weight ratio of the materials in the two cups.

[0026] refer to Figure 3 , Figure 7 The output end of the stirring motor 7 is bolted with a connecting flange 18. The top of the rotating stirring head 8 is snapped into one side inside the connecting flange 18. A plastic stirring sleeve 9 is slidably fitted onto the surface of the rotating stirring head 8, and the surface of the plastic stirring sleeve 9 has a groove 24. This positions the rotating stirring head 8 at a position off-center from the output shaft of the stirring motor 7, so that when the stirring motor 7 is turned on, it can drive the rotating stirring head 8 to rotate around the output shaft of the stirring motor 7.

[0027] refer to Figure 4 The output ends of both the stirring motor lifting cylinder 3 and the glue cup lifting cylinder 4 are fastened with cylinder fixing parts 19 that are bolted to the fixed plate 1. Air pipe connectors 26 are fixedly connected to the sides of both the stirring motor lifting cylinder 3 and the glue cup lifting cylinder 4 that are far apart from each other. This allows the stirring motor lifting cylinder 3 and the glue cup lifting cylinder 4 to be bolted to one side of the fixed plate 1 via the cylinder fixing parts 19.

[0028] refer to Figure 4 Both the output ends of the stirring motor lifting cylinder 3 and the glue cup lifting cylinder 4 are bolted with floating joints 20. Each floating joint 20 has a bracket sliding plate 21 bolted to its closest end. The two bracket sliding plates 21 are respectively bolted to the ends of the motor mounting bracket 5 and the glue cup lower support 6 near the stirring motor lifting cylinder 3 and the glue cup lifting cylinder 4. The stirring motor lifting cylinder 3 and the glue cup lifting cylinder 4 drive the floating joints 20 and the bracket sliding plates 21 to move, thereby allowing the bracket sliding plates 21 to drive the motor mounting bracket 5 and the glue cup lower support 6 to slide up and down on the other side of the fixed upright plate 1.

[0029] refer to Figure 6 A guide rail 22 is bolted to one side of the fixed upright plate 1 near the lifting cylinder 3 of the mixing motor and the lifting cylinder 4 of the glue cup. Sliding blocks 23, bolted to the sliding plate 21 of the bracket, are slidably connected to both the top and bottom sides of the guide rail 22. These blocks limit the vertical sliding of the motor mounting bracket 5 and the lower support of the glue cup 6, improving sliding stability.

[0030] Brief Description of Usage: First, it should be noted that this device is only used to measure the curing time of adhesives mixed in different proportions, and is for experimental testing purposes only. For example, adhesive A is the resin, and adhesive B is the hardener; hereinafter, they will be referred to as A and B. Adhesives A and B must be mixed in the correct proportions to cure. This device only needs to measure the curing time.

[0031] The weight ratio of adhesives A and B is controlled according to work requirements. A is poured into the first cup and weighed. B is poured into the second cup in the same proportion and weighed. The materials from the two cups are poured into the mixing cup. The cups are weighed using the weighing scale 11. After calculating the ratio based on the weight ratio of the materials in the two cups, the A and B adhesives from the two cups are poured into the adhesive cup 12. Then, place the glue cup 12 containing glues A and B onto the lower support 6. Using the spring force of spring 16, the spring rod 15 extends via the clamp 17, pressing the clamp 17 against the bottom surface of the glue cup 12, thus centering the glue cup 12 at the top center of the lower support 6. Next, activate the glue cup lifting cylinder 4 to press the top of the glue cup 12 against the bottom center of the upper fixing plate 13. Activate the stirring motor lifting cylinder 3, moving the motor mounting bracket 5 downwards to insert the rotating stirring head 8 into the glue cup 12, ensuring that a portion of the plastic stirring sleeve 9 remains exposed above the glue surface. Start the stirring motor 7 to begin stirring, while simultaneously measuring the curing time.

[0032] During the mixing process, the mixed adhesive gradually solidifies. Once it reaches the standard value, mixing is stopped, and the measured curing time is recorded. After mixing is complete, the dispensing cup lifting cylinder 4 is activated, causing the lower cup support 6 to move downwards, separating the dispensing cup 12 from the upper fixing plate 13. Simultaneously, the stirring motor lifting cylinder 3 is activated, causing the motor mounting bracket 5 to move upwards, and the rotating stirring head 8 is pulled out from inside the plastic stirring sleeve 9. Since the mixed adhesive has solidified, the plastic stirring sleeve 9 cannot be pulled out and remains inside the dispensing cup 12. This completes the curing time test for this group of mixed adhesives. The curing time data can then be submitted to the adhesive application equipment.

[0033] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0034] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
