Abstract
Description
Technical Field

[0002] Due to differences in glue preparation processes, many properties of glue vary. This is especially true when considering the curing time of the glue when designing the hot pressing time. In the application of wood product glue, a curing time of less than 120 seconds is generally required. Currently, this testing indicator is often determined by the inspector's own judgment of the curing stage. This is determined by manual stirring and visual observation. This process is highly subjective, leading to large operational and judgment errors, making it difficult to accurately determine the curing time of the glue.
[0003] Publication number "CN221007156U" describes an adhesive curing time detection device. This device primarily consists of a rotational resistance detector, a temperature control component, and a timing device. Based on the principle that rotational resistance increases abruptly during adhesive curing, the device measures rotational resistance in real time. When the resistance increases by more than 1.5 times, rotation is immediately stopped. The timing device records the operating time, which represents the curing time of the adhesive. This device automates the detection of adhesive curing time, ensuring uniform mixing speed during adhesive mixing, eliminating operational errors during the adhesive curing time detection process, and improving the accuracy of test results, making it suitable for industrial production.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0033] For example 1, please refer to Figures 1 to 8 The present invention discloses a device for detecting glue curing time, comprising a detection platform 1, a stand 3 connected to one side of the detection platform 1, a reinforcing rib 32 connected between the detection platform 1 and the stand 3, and an electric control box 5 mounted on the stand 3. A glue tank 2 is mounted on the detection platform 1 below the stand 3, and an extrusion assembly is mounted on the stand 3, with the extrusion assembly and the glue tank 2 being arranged in a vertical direction corresponding to each other.
[0034] In this embodiment, a detection platform 1 and a stand 3 are provided which are interconnected. An extrusion assembly is provided on the stand 3, and a glue tank 2 is provided on the detection platform 1. The glue is stored in the glue tank 2. After the glue is pre-cured, the extrusion assembly is started to extrude the pre-cured glue, and the time when the glue is completely cured is collected.
[0035] The extrusion assembly includes a cylinder 4 fixedly mounted on the top of the stand 3. The output rod end of the cylinder 4 is connected to a pressure sensor 6. The bottom of the pressure sensor 6 is connected to a connecting rod 34. The bottom end of the connecting rod 34 is connected to a pressure plate 7. The diameter of the pressure plate 7 and the inner diameter of the glue groove 2 have a difference of 5-8 mm.
[0036] Specifically, when the pre-cured glue is squeezed, the cylinder 4 is started, the output shaft end of the cylinder 4 is connected to the pressure sensor 6, the bottom of the pressure sensor 6 is connected to the connecting rod 34, and the bottom end of the connecting rod 34 is connected to the pressure plate 7. After pressing down, the pressure plate 7 applies force to the pre-cured glue, and the pressure sensor 6 is used to collect the pressure. If the pressure change value is within the value range set by the operator, it means that the glue has completed curing; if the above pressure value is outside the value range set by the operator, the value and the current detection time are recorded, and the wait continues before the next detection is carried out.
[0037] It should be noted that the electric control box 5 and the pressure sensor 6 are connected by electrical signals. During the process of the pressing plate 7 loading the pre-cured glue, the calibration data of the pressure sensor 6 is displayed through the electric control box 5 .
[0038] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 8 A stirring assembly is provided on one side of the glue tank 2, and the stirring assembly includes a support block 13. The upper surface of the support block 13 is rotatably connected to the transition shaft 35. One side of the support block 13 is connected to a support plate 14. The bottom surface of the support plate 14 is provided with a motor 15. The motor 15 and the transition shaft 35 are connected through a transmission belt 16. The top of the transition shaft 35 is connected to an arm plate 17, and the end of the arm plate 17 away from the transition shaft 35 is connected to a stirring rod 18.
[0039] A stirring assembly is provided on the detection platform 1. The stirring assembly stirs the glue during the pre-curing process of the glue, starts the forward and reverse switching of the motor 15, and uses the transmission belt 16 to drive the transition shaft 35 to rotate, thereby driving the arm plate 17 and the stirring rod 18 on the transition shaft 35 to swing back and forth in the glue. A rotation resistance detector is provided in the electrical control box 5. The rotation resistance detector is electrically connected to the motor 15. The stirring rod 18 is inserted into the glue to be tested for stirring, and the resistance required for the rotation of the stirring rod 18 is detected to determine the size of the rotation resistance. The detection data is displayed by the electrical control box 5, which can not only be used for subsequent comparison with the data obtained by the extrusion assembly to verify the detection data, but also the stirring assembly can be used to pre-curing the glue, and then the extrusion assembly can be used to perform a secondary detection of the glue curing time.
[0040] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 8 A flip plate 12 is connected to one side of the stirring assembly. As the extrusion assembly moves downward, the driving assembly drives the flip plate 12 to flip, raising the stirring assembly. The flip plate 12 is connected to one side of a support block 13. A support 11 is fixedly mounted on the inspection platform 1. The flip plate 12 is rotatably connected to the support 11. A second spring 31 is provided at the bottom of the support 11.
[0041] In this embodiment, a flip plate 12 is provided on one side of the stirring assembly, and the flip plate 12 is used to drive the stirring assembly to flip, thereby lifting the stirring assembly to provide a working space for the extrusion assembly. Specifically, the flip plate 12 is connected to one side of the support block 13. One end of the flip plate 12 sinks to lift the stirring assembly. A second spring 31 is provided at the bottom of the support block 13, which can provide a buffer when the stirring assembly is reset, and can also offset the vibration generated during the stirring process.
[0042] Example 4: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 8 Two sets of limiting rings 26 are symmetrically arranged on both sides of the glue groove 2. The inner diameter of the limiting ring 26 is larger than the outer diameter of the pressure plate 7, and the difference between the inner diameter of the limiting ring 26 and the outer diameter of the pressure plate 7 is 0.5-1mm. Guide rods 30 are symmetrically arranged on the outer wall of the glue groove 2. A traction plate 27 is connected to one side of the limiting ring 26. A vertical plate 28 is connected to the bottom of the traction plate 27. The vertical plate 28 and the guide rod 30 are slidably connected. A first spring 29 is arranged between the vertical plate 28 and the glue groove 2, and the first spring 29 is sleeved on the outside of the guide rod 30.
[0043] In this embodiment, two groups of limiting rings 26 are symmetrically arranged above the glue groove 2, and two groups of guide rods 30 are symmetrically arranged on both sides of the glue groove 2. The bottom of the limiting ring 26 is connected to a traction plate 27, and the traction plate 27 and the guide rod 30 are slidably connected. After the glue is pressed under the pressure plate 7, if the glue is not completely cured, the pressure plate 7 can be smoothly separated from the cured glue; if the glue is not completely cured, it may adhere to the glue. In order to prevent the uncured glue from being taken away from the glue groove 2 by the pressure plate 7, the limiting rings 26 on both sides can be combined to peel off the uncured glue and the pressure plate 7 in turn.
[0044] It should be noted that when the extrusion component applies pressure to the semi-cured glue, the glue has passed the pre-curing test of the stirring component. Therefore, although the glue is not completely cured, it is already in a semi-cured state and no liquid exists. Therefore, it can be peeled off using the limit ring 26.
[0045] Example 5: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 8The drive assembly includes a drive frame 8, which is connected to the output shaft end of the cylinder 4 through a connecting sleeve 33. Two sets of suspension rods 9 are symmetrically arranged at the bottom of the drive frame 8. The bottom ends of the suspension rods 9 are connected to the first drive block 10. The second drive block 25 is connected to the traction plate 27. The first drive block 10 and the second drive block 25 are both provided with an inclined surface on one side. The drive assembly also includes a traction part connected between the vertical plate 28 and the flip plate 12. The traction part includes a first traction rope 20 and a second traction rope 24. The first traction rope 20 is connected between the vertical plate 28 and the second traction rope 24. A groove 21 is provided in the detection platform 1. Four sets of rotating columns 19 are rotatably connected in the groove 21. Two sets of rotating cross columns 22 are rotatably connected in the groove 21 on one side of the support 11. A connecting shaft 23 is symmetrically connected to one end of the flip plate 12. The two ends of the second traction rope 24 are transmission-connected between the connecting shaft 23 and the rotating cross column 22. One end of the first traction rope 20 is fixedly connected to one side of the vertical plate 28 , and the other end of the first traction rope 20 is wound around the surface of the rotating horizontal column 22 . The first traction rope 20 is sequentially wound around the surfaces of the four groups of rotating columns 19 .
[0046] In this embodiment, the driving assembly can be used to drive the two sets of limit rings 26 to move closer to the center of the glue groove 2. While the pressure plate 7 presses the glue, the two sets of limit rings 26 are staggered. Specifically, the telescopic rod end of the cylinder 4 moves downward, driving the suspension rod 9 and the first driving block 10 at the bottom end of the suspension rod 9 to descend. During the downward movement of the first driving block 10, the second driving block 25 is pushed to drive the traction plate 27 to move horizontally. The traction plates 27 move toward each other, driving the limit rings 26 to merge, thereby achieving the above-mentioned beneficial effects.
[0047] Since the bottom of the traction plate 27 is connected to the vertical plate 28, the vertical plate 28 is connected to the first traction rope 20, one end of the first traction rope 20 is connected to the rotating horizontal column 22, the rotating horizontal column 22 is connected to the second traction rope 24, the other end of the second traction rope 24 is connected to the connecting shaft 23, and the connecting shaft 23 is symmetrically arranged at one end of the flip plate 12. Therefore, during the movement of the traction plate 27, the first traction rope 20 is pulled to pull one end of the flip plate 12 to sink, thereby lifting the stirring assembly and providing working space for the extrusion assembly during the downward movement of the extrusion assembly.
[0048] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
