However, in this method, the weighing pad, guide plate, and sensor pad are all rigid and fixedly connected to the pressure sensor. When the base paper reaches the weighing position, there will be a strong impact. If it is used too many times, the pressure sensor and the pad above or below it will be worn or damaged, resulting in a short service life and increased costs. Utility Model Content

[0023] See also Figure 1 and Figure 2 , is a base paper online automatic weighing device of the utility model, which includes a frame 1, a sliding guide rail 2 arranged on the frame 1, a roll paper positioning member 4 arranged on the sliding guide rail 2 and used to install the base paper 3, and a weighing mechanism 5 arranged on the frame 1 and used to weigh the base paper 3. Among them, the frame 1 can support and position the components of the base paper online automatic weighing device, the sliding guide rail 2 is specifically located at the upper end of the frame 1, the roll paper positioning member 4 is movably connected to the sliding guide rail 2, the base paper 3 is installed on the roll paper positioning member 4, the base paper 3 can follow the roll paper positioning member 4 to move on the sliding guide rail 2, so that the base paper 3 can be weighed at a specified position. The roll paper positioning member 4 is specifically a roll paper shaft on a papermaking machine.

[0024] Furthermore, the weighing mechanism 5 includes a positioning plate 51, a first weighing swing arm 52, a pad 53, a driving mechanism 54, a second weighing swing arm 55 and a pressure sensor 56. The positioning plate 51 is fixedly connected to the frame 1, the first weighing swing arm 52 is rotatably connected to the positioning plate 51, the pad 53 is fixedly connected to the first weighing swing arm 52, and the pad 53 is arranged corresponding to the roll paper positioning member 4, the pad 53 is used to abut against the roll paper positioning member 4 during the weighing process of the base paper online automatic weighing device, the output end of the driving mechanism 54 is connected to the first weighing swing arm 52, the fixed end of the driving mechanism 54 is connected to the second weighing swing arm 55, the first end of the second weighing swing arm 55 is rotatably connected to the frame 1, and the pressure sensor 56 abuts against the second end of the second weighing swing arm 55 to measure the weight of the base paper 3.

[0025] It can be understood that the first weighing swing arm 52 is rotatable relative to the frame 1, and the second weighing swing arm 55 is also rotatable relative to the frame 1. The driving mechanism 54 can drive the first weighing swing arm 52 to move, so that the first weighing swing arm 52 and the pad 53 can move downward away from the sliding guide rail 2, or the pad 53 can move upward to abut against the paper roll positioning member 4. Figure 1 As shown, when the online automatic weighing device is in a non-working state, the pad 53 and the first weighing swing arm 52 are in a position away from the sliding guide rail 2. At this time, the paper reel where the base paper 3 is located will not touch the first weighing swing arm 52 and the pad 53. Therefore, when the online automatic weighing device is in a non-working state, no matter how fast or slow the base paper 3 rolls, or how large or small the force is, it will not cause impact and wear to the components of the weighing mechanism 5, making the use of the base paper online automatic weighing device safer and longer in service life than ordinary weighing devices.

[0026] like Figure 2 As shown, when the base paper 3 needs to be weighed, after the base paper 3 is wound from the paper winding cylinder, it follows the paper winding positioning member 4 to the position corresponding to the weighing, and then under the action of the driving mechanism 54, the first weighing swing arm 52 and the pad 53 move upward at the same time. At this time, the pad 53 abuts against the paper winding positioning member 4, that is, the force of the base paper 3 acts on the pad 53. According to the transmission of force, the weight pressure of the base paper 3 passes through the pad 53, the first weighing swing arm 52, the driving mechanism 54, and the second weighing swing arm 55 in turn, and is finally transmitted to the pressure sensor 56, thereby measuring the weight of the base paper 3.

[0027] In some embodiments, the weighing mechanism 5 further includes a support member 57 connected to the frame 1 and used to position and support the pressure sensor 56, and the support member 57 can be fixedly connected to the frame 1. A limit member 58 is provided on the support member 57, and a limit groove is provided on the second weighing swing arm 55 to cooperate with the limit member 58. The limit member 58 and the limit groove are provided so that the second weighing swing arm 55 can only rotate along the height direction of the frame 1.

[0028] The driving mechanism 54 is a hydraulic cylinder or a pneumatic cylinder. The driving mechanism 54 may also be an electric drive, which may be set according to actual conditions and is not specifically limited here.

[0029] The frame 1 is provided with a buffer mechanism for buffering the roll paper positioning member 4 to prevent the roll paper positioning member 4 from damaging other components of the base paper online automatic weighing device due to the impact caused by the high-speed rotation. For example, the buffer mechanism is a buffer rod installed on the frame 1 and a spring connected to the buffer rod, and the compression effect of the spring is used to achieve the buffering effect.

[0030] The frame 1 is provided with a brake mechanism for positioning and locking the roll paper positioning member 4. When the roll paper positioning member 4 reaches the position corresponding to the weighing, the brake mechanism can be used to position and lock the roll paper positioning member 4, and then the measurement can be started. The brake mechanism is a mature structure of the existing papermaking machine, and it can be set and installed according to the actual situation.

[0031] A position sensor for detecting the position of the paper roll positioning member 4 is disposed on the frame 1. The position sensor can detect whether the paper roll positioning member 4 is in a correct measuring position. If it is in a correct measuring position, the weight of the base paper 3 can be measured.

[0032] The base paper online automatic weighing device also includes a control mechanism, which is communicatively connected with the driving mechanism 54, the position sensor and the pressure sensor 56 to control the operation of the entire base paper online automatic weighing device, realize automatic weighing, and automatically obtain the weight information of the base paper 3.

[0033] In general, due to the setting of the driving mechanism 54, when the online automatic weighing device is in a non-working state, no matter how fast or slow the rolling speed of the base paper 3 is, or how large or small the force is, it will not cause impact and wear to the parts of the weighing mechanism 5, making the use of the online automatic weighing device for base paper safer and longer in service life than ordinary weighing devices. When the roll paper positioning member 4 reaches the specified position on the sliding guide rail 2, the online automatic weighing device for base paper can directly weigh the base paper 3, and the weight pressure of the base paper 3 passes through the pad 53, the first weighing swing arm 52, the driving mechanism 54, and the second weighing swing arm 55 in turn, and is finally transmitted to the pressure sensor 56, thereby measuring the weight of the base paper 3. This weighing method is fast and convenient, saves time and space, and the device is safe and durable to use.

[0034] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should fall within the scope of the claims of the utility model.
