[0028] like Figure 1-5 As shown, a system for controlling the internal joints of a composite pultruded plate comprises a bracket 1, a control system, and a speaker 2. The bracket 1 is provided with a plurality of horizontal gravity detection rods, the gravity detection rod signals are connected to the control system, the control system signals are connected to the speaker 2, and each gravity detection rod on the bracket 1 corresponds to a number, which is pre-stored in the control system.

[0029] In this embodiment, after the number of each gravity detection rod is stored in the control system, a change function of the gravity detected on the gravity detection rod is set in the control system. That is to say, as the yarn 9 is consumed, the gravity detected on the gravity detection rod will gradually decrease. This change function is linear. Assuming that the consumption rate of yarn 9 in the process of manufacturing the pultruded plate is V, then every second, the gravity detected on the gravity detection rod at time T is M-VT, wherein M is the mass of the yarn 9 initially placed on each gravity detection rod, and T is the time elapsed after the yarn 9 is placed on each gravity detection rod. It can be seen from the formula that when the speed is constant, the gravity detected on the gravity detection rod changes linearly and gradually decreases. When the gravity detection rod detects that the gravity has not changed, the yarn 9 on the gravity detection rod is in a broken state, and the gravity detection rod transmits a signal to the control system, and the control system transmits the signal to the speaker 2, and the speaker 2 broadcasts the number of the gravity detection rod with broken yarn 9 to the worker, so that the worker can continue the yarn in time; when the gravity detected by the gravity detection rod is less than the minimum value pre-stored in the control system, it means that there is still a little bit of yarn 9 on the reel 10, but it needs to be continued. At this time, the gravity detection rod transmits a signal to the control system, and the control system transmits the signal to the speaker 2, thereby reminding the worker to continue the yarn 9 in time. Among them, before starting to make the pultruded board, the minimum value of the gravity detected by each gravity detection rod is pre-stored in the control system, and the time t that the gravity detection rod is allowed to detect that the gravity has not changed is also pre-stored in the control system. When the actual time T1 that the gravity detection rod detects that the gravity has not changed is greater than t, the control system controls the speaker 2 to broadcast the corresponding number. In this way, there is no need for workers to observe next to the bracket all the time.

[0030] As a preferred embodiment, the gravity detection rod includes a fixed rod 3, a load-bearing rod 4, and a gravity sensor 5. The fixed rod 3 is fixed on the fixed frame 1, and the load-bearing rod 4 is arranged directly above the fixed rod 3. The length line of the load-bearing rod 4 is parallel to the length line of the fixed rod 3. The projection of the upper surface of the load-bearing rod 4 on a plane perpendicular to the length line of the load-bearing rod 4 is an arc, and the side of the arc facing the fixed rod 3 is a concave side. A gravity sensor 5 is arranged on the upper surface of the fixed rod 3, and the load-bearing rod 4 is located on the sensing surface of the gravity sensor 5. The projection of the fixed rod 3 on the horizontal plane is surrounded by the projection of the load-bearing rod 4 on the horizontal plane. The signal of the gravity sensor 5 is connected to the control system.

[0031] After such design, the fixed rod 3 is used to support the column reel 10 and the load-bearing rod 4. When in use, the reel 10 is mounted on the whole composed of the fixed rod 3 and the load-bearing rod 4. The arc-shaped design is to enable the reel 10 to rotate on the whole composed of the fixed rod 3 and the load-bearing rod 4 during the process of consuming the yarn 9; the gravity sensor 5 is used to detect the weight of the yarn on the load-bearing rod 4; the design that the projection of the fixed rod 3 on the horizontal plane is surrounded by the projection of the load-bearing rod 4 on the horizontal plane is to facilitate the rotation of the reel 10 on the whole composed of the fixed rod 3 and the load-bearing rod 4 during the process of consuming the yarn 9, thereby avoiding the situation where the fixed rod 4 jams the reel 10 so that the reel 10 cannot rotate.

[0032] Gravity detection rod has two designs

[0033] Mode 1: The fixed rod 3 of the gravity detection rod is provided with a through hole 6 with a vertical axis, and the lower surface of the load-bearing rod 4 is provided with a limit column 7 that cooperates with the through hole 6, and the lower end of the limit column 7 extends into the through hole 6. In this way, the design of the limit column 7 and the through hole 6 prevents the load-bearing rod 4 from moving horizontally with the fixed rod 3, and at the same time, prevents the load-bearing rod 4 from falling off the fixed rod 3 during the rotation of the reel 10, and does not limit the gravity sensor 5 from detecting the gravity of the load-bearing rod 4, the reel 10 and the yarn 9 when preventing the load-bearing rod 4 from falling off the fixed rod 3.

[0034] Method 2: Figure 4-5 As shown, the central angle of the cross section of the bearing rod 4 is less than 180 degrees, and a groove 8 is provided on the lower surface of the bearing rod 4, and the length line of the groove 8 is parallel to the length line of the bearing rod 4. After such a design, the projection of the fixing rod 3 on the horizontal plane is specifically surrounded by the projection of the bearing rod 4 on the horizontal plane, thereby preventing the reel 10 from being stuck by the fixing rod 3, resulting in the gravity sensor 5 not being able to sense the weight of the bearing rod 4, the reel 10 and the yarn 9, and facilitating the assembly of the bearing rod 4 and the fixing rod 3 during the manufacturing process.

[0035] As a preferred embodiment, one end of the fixing rod 3 is fixedly connected to the bracket 1, and the other end is suspended. One end of the groove 8 is on the load-bearing rod 4, and the other end extends from the load-bearing rod 4 toward the end of the fixing rod 3 fixedly connected to the bracket 1 to the outside of the load-bearing rod 4. The end of the fixing rod 3 facing away from the bracket 1 is located in the groove 8.

[0036] As a preferred mode, the edge of the side wall of the groove 8 is provided with a rounded corner, and the lower surface of the fixing rod 3 is also provided with a rounded corner. The rounded corner is designed in this way to avoid limiting the rotation of the reel 10 during its rotation.

[0037] As a preferred mode, the lower surface of the load-bearing rod 4 is a plane, the edge on the lower surface of the load-bearing rod 4 is provided with a rounded corner, the projection of the fixing rod 3 in the horizontal plane is surrounded by the projection of the load-bearing rod 4 in the horizontal plane; the distance from the side of the fixing rod 3 facing away from the load-bearing rod 4 to the lower surface of the load-bearing rod 4 is less than the radius of the virtual circle where the arc is located. The purpose of this design is to prevent the reel 10 from being stuck by the fixing rod 3, resulting in the gravity sensor 5 not being able to sense the gravity of the load-bearing rod 4, the reel 10 and the yarn 9.

[0038] A composite material pultruded plate internal joint method, comprising the above system and the following steps:

[0039] 1) A reel 10 with yarn 9 is coaxially sleeved on each gravity detection rod, and the quality of the yarn 9 on each of the gravity detection rods is ensured to be different; this can prevent the yarn 9 on all the reels 10 from being consumed at the same time, causing the entire production line for pultruded plates to stop;

[0040] 2) The mass of each roll of yarn 9 is input into the control system in correspondence with the number of the gravity detection rod on which it is located; in this way, when the yarn 9 on the corresponding reel 10 needs to be connected, the speaker 2 can broadcast the number of the corresponding gravity detection rod, so that the worker knows the gravity detection rod to which the yarn 9 needs to be connected.

[0041] 3) Setting the minimum mass value that each gravity detection rod can bear in the control system;

[0042] 4) When the control system controls the speaker to report the number of the corresponding gravity detection rod, the tail end of the yarn 9 on the reel 10 on the gravity detection rod is connected to the head end of the yarn 9 on a new reel 10;

[0043] 5) Remove the old reel 10 and the yarn 9 on the reel 10 from the gravity detection rod in step 4), and then sleeve the new reel 10 with the yarn 9 wound around it on the gravity detection rod in step 4).
