[0021] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0022] This application provides a weighing device for roll material production, used to weigh the roll material at the unwinding station of a winding machine, such as... Figure 1-3 As shown, a pair of weighing devices 100 are arranged opposite each other at intervals along the axial direction of the roll 200, capable of carrying the roll 200 that is about to be unloaded and weighing the carried roll 200.

[0023] like Figure 4-7As shown, each weighing device 100 includes: a support frame 1, a support block 2 that is movably mounted on the support frame 1 in the vertical direction, a lifting cylinder 3 connected to the support block 2, and a weighing mechanism 4 for detecting the weight of the roll material on the support block 2.

[0024] The support frame 1 has a notch 101 at its top for the support block 2 to move up and down. The support frame 1 includes a pair of brackets 11 arranged opposite each other, a top plate 12 fixedly installed at the top of the pair of brackets 11, a bottom plate 13 fixedly installed at the bottom of the pair of brackets 11, and a pair of support side plates 14 fixedly installed on the left and right sides of the pair of brackets 11 respectively. The notch 101 is formed on the top plate 12.

[0025] The top of the support block 2 has a pair of support portions 21 that support the roll 200 in the circumferential direction. The pair of support portions 21 are arranged opposite each other and perpendicular to each other in the same plane. In this embodiment, the distance between the front end of the front support portion 21 and the rear end of the rear support portion 21 is greater than the size of the notch 101 in the front-back direction, ensuring that the pair of support portions 21 are always located on the upper side of the notch 101.

[0026] The lifting cylinder 3 is located below the support block 2 and is fixedly installed on the base plate 13. The top of the cylinder body of the lifting cylinder 3 is connected to a pair of support side plates 14 through a cylinder connecting plate 31, thereby increasing the stability of the connection between the lifting cylinder 3 and the support frame 1. The weighing mechanism 4 is installed between the support block 2 and the lifting cylinder 3 to weigh the roll material 200 when the support block 2 is carrying it, and effectively improves the accuracy of the roll material weighing. The telescopic rod of the lifting cylinder 3 is connected to the bottom of the weighing mechanism 4, and the top of the weighing mechanism 4 is connected to the support block 2. The lifting cylinder 3 pushes the weighing mechanism 4 and its connected support block 2 to move up and down synchronously from below.

[0027] A first guide mechanism 5 is provided between the support block 2 and the support frame 1. The first guide mechanism 5 is used to limit the lifting direction of the support block 2. A second guide mechanism 6 is provided between the weighing mechanism 4 and the support frame 1. The second guide mechanism 6 is used to limit the lifting direction of the weighing mechanism 4.

[0028] like Figure 3 , 5As shown in Figures 7 and 8, the first guiding mechanism 5 includes a guide roller 51 rotatably mounted on the top plate 12 about its own axis, a ball bearing 53 sleeved on the guide roller 51, and a guide groove 52 formed on the support block 2. The axis of the guide roller 51 extends in the left-right direction and passes through the guide groove 52, which extends in the up-down direction. The ball bearing 53 rolls in cooperation with the guide groove 52. When the support block 2 moves up and down in the up-down direction, the ball bearing 53 rolls in the guide groove 52. On the one hand, the guide groove 52 restricts the movement of the guide roller 51 in the front-back direction, ensuring that the support block 2 does not shift in the front-back direction when it moves up and down. On the other hand, the rolling cooperation between the ball bearing 53 and the guide groove 52 reduces the friction between the support block 2 and the top plate 12 when it moves up and down, ensuring the smoothness of the support block 2's movement.

[0029] like Figure 3 , 4 As shown in Figures 6 and 7, the second guiding mechanism 6 includes a pair of guiding components 61 arranged opposite each other on the left and right sides. Each guiding component 61 includes a guide rod 611 extending in the vertical direction and a slider 612 sleeved on the guide rod 611. The top end of the guide rod 611 is fixedly connected to the top plate 12, and the bottom end of the guide rod 611 is fixedly connected to the support side plate 14 on the corresponding side. The slider 612 is fixedly connected to the weighing mechanism 4. When the weighing mechanism 4 is raised and lowered by the lifting cylinder 3, the sliding cooperation between the slider 612 and the guide rod 611 of the pair of guiding components 61 allows the weighing mechanism 4 to move horizontally up and down in the left-right and front-back directions.

[0030] The first guiding mechanism 5 and the second guiding mechanism 6 work together to guide the lifting and lowering of the support block 2 and the weighing mechanism 4, preventing them from shifting in the front-back and left-right directions during movement, and ensuring that the support block 2 provides stable support for the roll material 200.

[0031] The distance between the support side plate 14 and the top plate 12 is greater than the extension distance of the telescopic rod of the lifting cylinder 3, so as to ensure that the lifting cylinder 3 has sufficient distance to drive the support block 2 to rise and fall.

[0032] like Figure 1-4 As shown, a pair of support components 7 are also installed on one side of the top plate 12, which are arranged opposite each other. Each support component 7 includes a pair of support rollers 71 arranged opposite each other. Each support roller 71 is rotatably mounted on the support frame 1 around its own axis, and the axis of each support roller 71 extends in the left-right direction.

[0033] When a weighing device 100 weighs the unwound roll 200 at the unwinding station of the winding machine, a pair of support components 7 of each weighing device 100 are used to support the rollers on both sides of the roll 200 to avoid affecting the weighing of the roll 200.

[0034] A lifting cylinder of a weighing device drives a pair of support blocks upward to lift the roll material to be unloaded on the winding machine, and weighs the lifted roll material at the same time, realizing automatic weighing of the roll material, and effectively ensuring the stability, accuracy and speed of the weighing process. The weighing device has a simple structure, is easy to adjust, and effectively reduces the cost of use.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made without departing from the spirit and scope of this application. The scope of protection claimed by this application is defined by the appended claims, specification, and their equivalents.
