Description

Technical Field

[0001] This utility model specifically relates to a paper storage force control device for a non-stop unwinding machine, belonging to the field of unwinding machine technology. Background Technology

[0002] In the production processes of industries such as papermaking, printing, and packaging, non-stop unwinding machines are essential equipment. They enable paper roll changes without interrupting production, thereby improving efficiency. The paper tension control device is a key component of the non-stop unwinding machine. Its function is to ensure that the paper maintains constant tension during unwinding, preventing problems such as wrinkles and tears, thus guaranteeing product quality.

[0003] Currently, there are already some control devices for storing paper tension in the prior art. For example, Chinese invention patent document, publication number CN101811627A, discloses a control device for storing paper tension. This device is placed between an intermittent feeding traction device and a continuous feeding traction device. It includes a fixed support frame, a fixed feed roller, a movable feed roller, a storage support frame, a linear guide rail, a gear rack and pinion, and a motor. Controlled by the motor, it can ensure more stable paper tension, is suitable for high-speed production, and has a more compact structure, saving space.

[0004] For example, the Chinese invention patent document with announcement number CN109665352B discloses a tension control device for an unwinding system. By adding a clamping mechanism at the front end of the material storage mechanism and supplementing it with a simple control algorithm, it achieves constant tension control of the material during the roll changing process, making the subsequent winding tension control easier to achieve and more precise, which can effectively improve the quality of processed products.

[0005] However, existing paper tension control devices still have some shortcomings. Some devices lack sufficient control precision, making it difficult to accurately control paper tension, resulting in large tension fluctuations during unwinding and affecting product quality; some devices have complex structures, high manufacturing costs, and are difficult to maintain, increasing production costs for enterprises; most control devices rely on motors for control, which increases costs while also reducing reliability. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a paper storage force control device for a non-stop unwinding machine, which can solve the problems of high control costs and poor reliability of the device itself in existing technologies.

[0007] A paper storage force control device for a non-stop unwinding machine includes a base plate, with a space for storing paper rolls between the base plates. An adjusting cylinder is installed on the outer wall of the base plate. When the air source is connected, the cylinder can assist in controlling the movement of a counterweight. When the air source is not connected, the paper is pulled by the weight of the counterweight alone. A guide mechanism is provided above the cylinder. The guide mechanism is used to make reasonable use of the weight of the counterweight to pull the paper, thereby achieving a labor-saving effect. The guide mechanism includes an upper reversing wheel installed on the top of the base plate and a lower reversing wheel installed on the lower part of the inner side wall of the base plate. A counterweight is fixed to the top of the adjusting cylinder. A traction rope is fixed to the top of the counterweight. One end of the traction rope passes over the top of the upper reversing wheel and extends downward to pass under the lower reversing wheel. Finally, the traction rope slides around one end of a floating roller. A paper roll, which is a printed object or an unwound object, is wound on the floating roller. A power connector is provided on one side of the base plate through a power cord.

[0008] A guide rail groove is provided on the outer side wall of the substrate, and a slider is fixed on the side wall of the counterweight. The slider is slidably engaged in the guide rail groove. An auxiliary horizontal plate is fixed on the side wall of the counterweight. The guide groove is used to limit the movement trajectory of the counterweight.

[0009] A control component is installed on the outer wall of the substrate. The control component includes a buffer telescopic rod fixed on the outer wall of the substrate. An electronic ruler is fixed on the outer wall of the substrate. The measuring end of the electronic ruler is located below the auxiliary horizontal plate. The control component is used to control the tension of the paper. When in use, it also needs to be used in conjunction with an external control system. The electronic ruler can feed back the measured position data to the external control system when it is triggered.

[0010] The buffer telescopic rod includes a temporary storage cylinder fixed to the outer wall of the substrate. The temporary storage cylinder is fixed to both the upper and lower parts of the substrate. A connecting rod is slidably engaged inside the temporary storage cylinder. The connecting rod passes through the auxiliary crossbar and is fixedly connected to the auxiliary crossbar. The temporary storage cylinder has a space to accommodate the sliding of the connecting rod inside, thereby controlling the paper tension by restricting the movement of the connecting rod.

[0011] A hydraulic cylinder is fixed on the outer wall of the substrate. A pipe opening is provided on one side of the hydraulic cylinder. The pipe opening is connected to an oil filter through a pipe. A control valve is connected to one side of the oil filter through a connecting pipe. The control valve is connected to the far end of a temporary storage cylinder through an output pipe. The control valve is used to control the flow rate of the oil, thereby controlling the movement of the counterweight.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Reduced control costs: This device can pull the paper by the weight of the counterweight alone when the air source is not connected, reducing the dependence on power equipment such as motors and avoiding the high cost problems caused by the use of motors, thus effectively reducing control costs.

[0014] 2. Improve device reliability: By abandoning the method of relying on motor control for most control devices, the unreliability of the device caused by motor failure is reduced. Tension control is achieved by using simple mechanical structures such as counterweights, cylinders, and guide mechanisms, which makes the structure simpler and more reliable.

[0015] 3. Precise tension control: The electronic ruler in the control component can feed back the measured position data to the external control system. In conjunction with the buffer telescopic rod, hydraulic cylinder, control valve, etc., the flow rate of the oil and the movement of the counterweight can be precisely controlled, thereby precisely controlling the paper tension and avoiding the problem of large tension fluctuations during the unwinding process, ensuring product quality.

[0016] 4. Make reasonable use of gravity: The guiding mechanism includes an upper reversing wheel and a lower reversing wheel. It makes reasonable use of the gravity of the counterweight to pull the paper, achieving a labor-saving effect and improving the working efficiency of the device.

[0017] 5. Provides movement trajectory restriction: The guide rail groove on the outer wall of the base plate and the slider on the side wall of the counterweight cooperate with each other, as well as the setting of the auxiliary horizontal plate and guide groove, to provide movement trajectory restriction for the counterweight, ensuring the stability and accuracy of the device operation.

[0024] Please see Figure 1-4 As shown, a paper storage force control device for a non-stop unwinding machine includes a base plate 1, with a space for storing paper rolls between the base plates 1. An adjusting cylinder 2 is installed on the outer wall of the base plate 1. When the air source is connected, the cylinder can assist in controlling the movement of the counterweight 303. When the air source is not connected, the paper is pulled by the weight of the counterweight 303 alone. A guide mechanism 3 is provided above the cylinder. The guide mechanism 3 is used to make reasonable use of the gravity of the counterweight 303 to pull the paper, thereby achieving a labor-saving effect. The guide mechanism 3 includes an upper reversing wheel 301 installed on the top of the base plate 1 and a lower reversing wheel installed on the lower part of the inner side wall of the base plate 1. 302, A counterweight 303 is fixed to the top of the adjusting cylinder 2, and a traction rope 304 is fixed to the top of the counterweight 303. One end of the traction rope 304 passes over the upper reversing wheel 301 and extends downward to pass under the lower reversing wheel 302. Finally, the traction rope 304 is slidably sleeved on one end of the floating roller. A paper roll is wound on the floating roller. The paper roll is the printed material or the unwound material. The winding direction and front and back parts of the paper need to be controlled by the paper storage structure between the base plates 1. The floating roller slides up and down and is locked between the base plates 1. The floating roller can rotate on its own. A power connector is provided on one side of the base plate 1 through a power cord.

[0025] A guide rail groove 101 is provided on the outer side wall of the substrate 1. A slider 305 is fixed on the side wall of the counterweight 303. The slider 305 is slidably engaged in the guide rail groove 101. An auxiliary horizontal plate 4 is fixed on the side wall of the counterweight 303. The guide groove is used to limit the movement trajectory of the counterweight 303.

[0026] A control component 5 is installed on the outer side wall of the substrate 1. The control component 5 includes a buffer telescopic rod 51 fixed on the outer side wall of the substrate 1 and an electronic ruler 52 fixed on the outer side wall of the substrate 1. The measuring end of the electronic ruler 52 is located below the auxiliary horizontal plate 4. The control component 5 is used to control the tension of the paper. When in use, it also needs to be used in conjunction with an external control system. The electronic ruler 52 can feed back the measured position data to the external control system when it is triggered.

[0027] The buffer telescopic rod 51 includes a temporary storage cylinder 511 fixed on the outer wall of the base plate 1. The temporary storage cylinder 511 is fixed at both the upper and lower parts of the base plate 1. A connecting rod 512 is slidably engaged inside the temporary storage cylinder 511. The connecting rod 512 passes through the auxiliary crossbar and is fixedly connected to the auxiliary crossbar. The temporary storage cylinder 511 has a space inside to accommodate the sliding of the connecting rod 512, thereby controlling the paper tension by restricting the movement of the connecting rod 512.

[0028] A hydraulic cylinder 53 is fixed on the outer wall of the base plate 1. A pipe opening is provided on one side of the hydraulic cylinder 53. The pipe opening is connected to an oil filter 54 through a pipe. A control valve 55 is connected to one side of the oil filter 54 through a connecting pipe. The control valve 55 is connected to the far end of a temporary storage cylinder 511 through an output pipe. The control valve 55 is used to control the flow rate of the oil, thereby controlling the movement of the counterweight 303.

[0029] The control component 5 mainly plays the role of controlling paper tension. The electronic ruler 52 measures the position of the auxiliary horizontal plate 4 and feeds the data back to the external control system. The temporary storage cylinder 511 of the buffer telescopic rod 51 accommodates the sliding of the connecting rod 512, restricting the movement of the connecting rod 512 and thus controlling the paper tension. The oil cylinder 53 is connected to the temporary storage cylinder 511 through the port, pipe, oil filter 54, connecting pipe, control valve 55 and output pipe. The control valve 55 controls the oil flow speed, thereby controlling the movement of the counterweight 303 to achieve precise control of paper tension.

[0030] When using it, first place the paper roll in the storage space between the base plates 1, connect the power cord and the power connector, and decide whether to connect the air source according to actual needs. Only when the electronic ruler 52 is abnormally triggered should the external control air source be intervened.

[0031] When the external control system is activated, the electronic ruler 52 starts working, monitoring the position of the counterweight 303 in real time. The operator can adjust the oil flow rate through the control valve 55 according to the paper tension to adjust the movement of the counterweight 303, ensuring that the paper maintains constant tension during unwinding and avoiding problems such as wrinkles and breaks.
