[0028] As Figures 1-5 shown, a system for controlling the joint in the composite material pultruded plate, comprising a support 1, a control system, a horn 2, a plurality of horizontal gravity detection rods are arranged on the support 1, the gravity detection rod signal is connected to the control system, the control system signal is connected to the horn 2, each gravity detection rod on the support 1 corresponds to a number, the number 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, 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 speed V of the yarn 9 in the process of manufacturing the pultruded plate, 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, T is the time elapsed after the yarn 9 is placed on each gravity detection rod. From the formula, it can be seen that when the speed is constant, the gravity detected on the gravity detection rod is linearly changed and gradually decreases. When the gravity detection rod detects that the gravity does not change, at this time the yarn 9 on the gravity detection rod is in a broken state, the gravity detection rod transmits a signal to the control system, the control system transmits a signal to the horn 2, and the horn 2 broadcasts the number of the gravity detection rod of the broken yarn 9 to the worker, so that the worker can timely splice the yarn; when the gravity detected by the gravity detection rod is less than the minimum value pre-stored in the control system, it represents that there is still a little bit of margin for the yarn 9 on the reel 10, but it needs to be spliced, at this time the gravity detection rod transmits a signal to the control system, the control system transmits a signal to the horn 2, thereby reminding the worker to timely splice the yarn 9. Wherein, before starting to make the pultruded plate, the minimum value of the gravity detected by each gravity detection rod allowed in the control system is pre-stored, and the time t during which the gravity detection rod is allowed to detect that the gravity does not change is also pre-stored in the control system, when the time T1 during which the actual gravity detection rod detects that the gravity does not change is greater than t, the control system controls the horn 2 to broadcast the corresponding number. In this way, the worker does not need to observe at the support 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 bracket 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 the 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 this design, the fixed rod 3 is used to support the 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 consumption of the yarn 9; the gravity sensor 5 is used to detect the weight of the yarn on the load-bearing rod 4; 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, so that the reel 10 can rotate on the whole composed of the fixed rod 3 and the load-bearing rod 4 during the consumption of the yarn 9, thereby avoiding the situation where the fixed rod 3 is stuck on the reel 10 so that the reel 10 cannot rotate.

[0032] The gravity detection rod has two designs

[0033] Method 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 limiting post 7 that cooperates with the through hole 6, and the lower end of the limiting post 7 extends into the through hole 6. In this way, the design of the limiting post 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. In addition, when preventing the load-bearing rod 4 from falling off the fixed rod 3, the gravity sensor 5 will not be restricted from detecting the gravity of the load-bearing rod 4, the reel 10 and the yarn 9.

[0034] Method 2: Figures 4-5 As shown, the central angle of the cross section of the carrying rod 4 is less than 180 degrees, and a groove 8 is provided on the lower surface of the carrying rod 4, the length of the groove 8 being parallel to the length of the carrying rod 4. This design specifically achieves the purpose of surrounding the projection of the fixing rod 3 on the horizontal plane by the projection of the carrying 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 carrying rod 4, the reel 10, and the yarn 9. At the same time, it facilitates the assembly of the carrying rod 4 and the fixing rod 3 during the manufacturing process.

[0035] As a preferred mode, one end of the fixed rod 3 is fixedly connected with the support 1, and the other end is suspended. One end of the groove 8 is on the bearing rod 4, and the other end extends from the bearing rod 4 to outside the bearing rod 4 towards the end of the fixed rod 3 fixedly connected with the support 1. The end of the fixed rod 3 away from the support 1 is located in the groove 8.

[0036] As a preferred mode, a round corner is arranged on the edge of the side wall of the groove 8, and a round corner is also arranged on the lower surface of the fixed rod 3. The round corner is designed to avoid limiting the rotation of the winding drum 10 during the rotation of the winding drum 10.

[0037] As a preferred mode, the lower surface of the bearing rod 4 is a plane, a round corner is arranged on the edge of the lower surface of the bearing rod 4, the projection of the fixed rod 3 in the horizontal plane is surrounded by the projection of the bearing rod 4 in the horizontal plane, and the distance from the side of the fixed rod 3 away from the bearing rod 4 to the lower surface of the bearing rod 4 is less than the radius of the virtual circle on which the arc is located. The design purpose is to prevent the winding drum 10 from being stuck by the fixed rod 3, resulting in the situation that the gravity sensor 5 cannot sense the gravity of the bearing rod 4, the winding drum 10 and the yarn 9.

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

[0039] 1) A winding drum 10 wound with a yarn 9 is coaxially sleeved on each gravity detection rod, and the mass of the yarn 9 on each gravity detection rod is different. This can prevent the situation that all the yarns 9 on the winding drums 10 are consumed at the same time, resulting in the stop of the entire production line of the pultruded plate;

[0040] 2) The mass of each winding drum 9 is input into the control system in correspondence with the number of the gravity detection rod on which the winding drum 9 is located. This facilitates the horn 2 to broadcast the number of the corresponding gravity detection rod when the yarn 9 on the corresponding winding drum 10 needs to be connected, so that the worker knows the gravity detection rod whose yarn 9 needs to be connected.

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

[0042] 4) After the control system controls the horn to broadcast the number of the corresponding gravity detection rod, the tail end of the yarn 9 on the winding drum 10 on the gravity detection rod is connected with the head end of the yarn 9 on a new winding drum 10;

[0043] 5) The old winding drum 10 and the yarn 9 on the winding drum 10 on the gravity detection rod in step 4) are removed, and then a new winding drum 10 wound with a yarn 9 is coaxially sleeved on the gravity detection rod in step 4).
