Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a dance system in which the weight of a counterweight can be automatically and infinitely adjusted. Background Art

[0002] In the production lines of the cable industry such as continuous extrusion, a dancing wheel system is usually placed before the take-up machine for wire winding to buffer and compensate for fluctuations in the product line speed. The existing dancing wheel system counterweights are generally in the form of weights, which are adjusted manually. Moreover, the counterweights are mostly superimposed by weights, and the weight cannot be adjusted infinitely. During the operation of the production line, the counterweights always move with the moving wheel, so the weight of the counterweights cannot be adjusted during the production process. However, in actual production, depending on the cross-sectional area of ​​the product, the weight of the counterweight often needs to be adjusted quickly and in a timely manner. If the counterweight is too heavy, the product will be thinned or even broken; if the counterweight is too light, the product cannot be effectively tightened, affecting the winding. Utility Model Content

[0003] The utility model aims to overcome the above problems and provide a dance system in which the weight of the counterweight can be automatically and infinitely adjusted.

The linear guide is vertically connected to the bracket. The moving wheel can slide up and down along the linear guide. The linear sensor is a slider type. The slider is connected to the moving wheel to detect the height of the moving wheel in real time to ensure that the moving wheel maintains a relatively fixed height position when working; the control mechanism includes a PLC controller, a forward contactor and a reverse contactor. The PLC controller is connected to the tension sensor and the linear sensor, and controls and adjusts the input voltage of the bidirectional water pump through the forward contactor and the reverse contactor to change its water suction and discharge direction.

[0005] The counterweight water tank is suspended in the air through a tension sensor, and the volume of the water storage tank is greater than that of the counterweight water tank.

[0006] The water outlet end of the spiral water pipe is fixedly connected to the counterweight water tank, and stretches when subjected to tension, and automatically contracts when not subjected to force.

[0007] The PLC controller is provided with a pre-set program, and the counterweight parameters are input through a touch screen connected thereto. The PLC controller automatically controls the forward contactor and the reverse contactor through the weight value detected by the tension sensor, thereby matching the counterweight weight with the input value.

[0008] The speed measuring wheel is provided with an encoder connected to the PLC controller to detect the speed of the speed measuring wheel in real time, so as to detect the traveling speed of the product and provide a basis for the wire taking-up speed for the wire taking-up machine.

[0009] The utility model utilizes the dead weight of water as the counterweight, and adjusts the weight by adjusting the water volume, so that the dancing wheel system in production can automatically adjust the counterweight weight.

DETAILED DESCRIPTION

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to the specific embodiments. Example

[0015] like Figure 1-Figure 3As shown, a dance system with a counterweight that can be automatically and infinitely adjusted includes a speed measuring wheel 2, a bracket 3, a front fixed wheel 4, a rear fixed wheel 6, and a moving wheel 8, and also includes a counterweight assembly 9 that can automatically and infinitely adjust the counterweight, the counterweight assembly 9 includes a counterweight water tank 901, a water storage tank 904, an adjustment mechanism and a control mechanism, the counterweight water tank 901 and the water storage tank 904 are connected through a two-way water pump 903 and a spiral water pipe 902, the two-way water pump 903 is connected to the control mechanism, the counterweight water tank is connected to the moving wheel 8 through a tension sensor 909, and the moving wheel 8 is connected to the adjustment mechanism; the adjustment mechanism includes a linear guide rail 5, a linear guide rail 5, a linear guide rail 6, a linear guide rail 7, a linear guide rail 8, a linear guide rail 9 ... Linear sensor 7, the linear guide 5 is vertically connected to the bracket 3, the moving wheel 8 can slide up and down along the linear guide 5, the linear sensor 7 is a slider type, the slider is connected to the moving wheel 8, the height of the moving wheel 8 is detected in real time, and the moving wheel 8 is guaranteed to maintain a relatively fixed height position when working; the control mechanism includes a PLC controller 907, a forward contactor 905 and a reverse contactor 906, the PLC controller 907 is connected to the tension sensor 909 and the linear sensor 7, and controls and adjusts the input voltage of the two-way water pump 903 through the forward contactor 905 and the reverse contactor 906 to change its water suction and water discharge direction.

[0016] The counterweight water tank 901 is suspended in the air through a tension sensor 909 , and the volume of the water storage tank 904 is greater than that of the counterweight water tank 901 .

[0017] The water outlet end of the spiral water pipe 902 is fixedly connected to the counterweight water tank 901, and stretches when subjected to tension, and automatically contracts when not subjected to force.

[0018] The PLC controller 907 is provided with a preset program, and the counterweight parameters are inputted through the touch screen 908 connected thereto. The PLC controller 907 automatically controls the forward contactor 905 and the reverse contactor 906 through the weight value detected by the tension sensor 909, thereby matching the counterweight weight with the input value.

[0019] The speed measuring wheel 2 is provided with an encoder connected to the PLC controller 907 to detect the rotation speed of the speed measuring wheel 2 in real time, so as to detect the traveling speed of the product 1 and provide a basis for the winding speed for the winding machine.

[0020] The working process of the utility model is as follows: before working, the PLC controller 907 is provided with a pre-set program, and the counterweight parameters are input through the touch screen 908 connected thereto. The PLC controller 907 automatically controls the forward contactor 905 and the reverse contactor 906 through the weight value detected by the tension sensor 909, so as to match the counterweight weight with the input value. During work, the speed encoder detects the travel speed of the product 1 in real time, provides the main basis for the take-up of the wire take-up machine, matches the take-up speed of the wire take-up machine, and the linear sensor 7 assists in the take-up. When the travel speed of the product 1 fluctuates, for example: when the main engine speed increases or decreases, and the speed of the product 1 speeds up or slows down, the moving wheel 8 will drop or rise, and the linear sensor 7 will drop or rise accordingly. At this time, the PLC controller 907 will increase or decrease the take-up speed of the wire take-up machine according to the pre-set program, so that the moving wheel 8 rises or falls, so that the moving wheel 8 always remains in the relative position in the middle of the stroke during the production process to ensure the stability of the take-up.

[0021] During the production process, if the product size needs to be slightly adjusted without stopping the machine, it can be achieved by adjusting the counterweight within a reasonable range. If the counterweight is increased, the cross-sectional area of ​​the product will decrease; if the counterweight is reduced, the cross-sectional area of ​​the product will increase. This is impossible with the traditional dancing wheel system.

For ordinary technicians in the technical field to which the utility model belongs, simple deductions and substitutions can be made without departing from the concept of the utility model, which should be regarded as the protection scope of the utility model.
