[0001] This utility model relates to the field of paper core processing technology, and in particular to a positioning and transmission device for paper core processing. Background Technology
[0002] In today's paper core processing industry, paper cores are widely used in many fields such as packaging, papermaking, textiles, and printing. Their processing quality and production efficiency directly affect the quality of downstream products and the economic benefits of enterprises. The paper core processing process is complex, covering multiple stages such as winding, cutting, polishing, and gluing. In the entire processing process, precise positioning and stable transfer of paper cores are the key to ensuring the smooth operation of each process and guaranteeing the uniformity of product quality.
[0003] However, in the existing technology, the paper core positioning and transmission device has problems such as inaccurate positioning and easy displacement or shaking of the paper core during the transmission process, which leads to a decrease in the quality of paper core processing and a reduction in production efficiency. Therefore, a positioning and transmission device for paper core processing is proposed. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a positioning and transmission device for paper core processing, comprising a support frame, a conveying mechanism installed in the middle of the support frame, a control system installed at the front end of the support frame, and a fixing mechanism provided at the upper end of the support frame. The fixing mechanism includes two sets of mounting plates and two sets of arc-shaped frame plates. A vertical seat is installed at the upper end of each of the two sets of mounting plates, and a telescopic rod is installed through one end of each of the two sets of vertical seats. A push plate is installed at the extended end of each of the two sets of telescopic rods, and an infrared sensor is installed at the upper end of each of the two sets of push plates.
[0006] Preferably, the lower ends of the two sets of mounting plates are symmetrically mounted on the upper end of the support frame, and one end of the two sets of arc-shaped frame plates is fixed to the other end of the two sets of push plates respectively.
[0007] Preferably, both sets of telescopic rods are connected to the control system signal, and both sets of infrared sensors are connected to the control system signal.
[0008] Preferably, two sets of guide rods are slidably installed through one end of each of the two sets of vertical seats, and one end of each pair of guide rods is fixed to one end of a push plate.
[0009] Preferably, the inner walls of both sets of arc-shaped frame plates are equipped with protective pads.
[0010] Preferably, the conveyor belt surface of the conveyor mechanism is equipped with multiple sets of limiting seats, and each set of limiting seats has a limiting groove at one end. The conveyor mechanism is signal-connected to the control system.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting a fixing mechanism, the arc-shaped frame plate in the fixing mechanism is closely fitted with the outer circular surface of the paper core, and the telescopic rod provides stable thrust. With the precise guidance of the guide rod, it can not only fix the paper core and prevent the paper core from shifting or shaking during processing, thus improving the quality and production efficiency of paper core processing, but also the setting of the infrared sensor can accurately detect the position of the paper core, ensuring accurate stopping and positioning at the designated processing position, effectively avoiding processing defects caused by inaccurate positioning, and greatly improving the accuracy and consistency of paper core processing.
[0012] 2. In this utility model, the entire device achieves fully automatic operation under the coordination of the control system. From feeding, conveying, positioning, processing to unloading of the paper core, no manual intervention is required. After the infrared sensor detects the paper core, it automatically triggers the positioning action. After processing is completed, it automatically releases and continues to convey, realizing continuous production. This not only reduces labor costs but also reduces errors caused by human operation and improves production efficiency.

The bolt heads are hexagonal for easy installation and disassembly. The surface of mounting plate 21 is galvanized to improve its corrosion resistance. The arc-shaped frame plate 22 is injection molded from high-strength engineering plastic. The arc is designed according to the outer diameter of common paper cores. Connecting ears are provided at both ends of the arc-shaped frame plate 22. Bolt holes are opened on the ears. It is connected to the push plate 25 by bolts. The inner wall of the arc-shaped frame plate 22 is roughened on the side that is in contact with the protective pad 28 to enhance the adhesion to the protective pad 28. The vertical base 23 is machined from a rectangular steel block. The vertical base 23 is vertically welded to the upper end of the mounting plate 21. The welding is done with a bevel weld and is annealed after welding to eliminate internal stress. The vertical base 23 has through holes that cooperate with the telescopic rod 24. The cylinder body of the telescopic rod 24 is connected to the vertical seat 23 via a flange. The flange has evenly distributed bolt holes that mate with the threaded holes on the vertical seat 23. The end of the piston rod is provided with a connecting thread and is fixedly connected to the push plate 25 via a nut. A magnetic switch is installed on the telescopic rod 24 to detect the extension and retraction position of the piston rod in real time. The push plate 25 is made of steel plate. One end of the push plate 25 is provided with a threaded hole that matches the piston rod of the telescopic rod 24, and the other end is provided with a connecting hole that matches the connecting lug of the arc-shaped frame plate 22. The surface of the push plate 25 is sprayed with a light gray color to facilitate observation of the surface condition. The infrared sensor 26 is a diffuse infrared sensor.

The protective pad 28 is made of nitrile rubber and its shape matches the inner wall of the arc-shaped frame plate 22. It is pasted on the inner wall of the arc-shaped frame plate 22 with special glue.
[0020] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, multiple sets of limit seats 12 are installed on the surface of the conveyor belt in the conveyor mechanism 11. Each set of limit seats 12 has a limit groove 14 at one end. The conveyor mechanism 11 is connected to the control system 13 by signal.
[0021] The overall effect achieved by the embodiment is as follows: the limiting seat 12 and the limiting groove 14 are: the limiting seat 12 is injection molded from polyoxymethylene plastic, and its length is adapted to the width of the conveyor belt. The limiting seat 12 is evenly installed on the surface of the conveyor belt by countersunk bolts. The distance between two adjacent limiting seats 12 is 100-300mm, and the specific distance is determined according to the length of the paper core. The limiting groove 14 is opened at one end of the limiting seat 12, and the inner wall of the groove is smoothed.
[0022] The operation method and working principle of this device are as follows: Before starting the device, the operator sets the parameters through the touch screen operation interface of the control system 13, including the diameter, length, transmission speed, positioning clamping force, etc. According to the diameter of the paper core, select the arc-shaped frame plate 22 with a suitable curvature and install it on the push plate 25 with bolts. At the same time, adjust the distance between the limit seat 12 and the conveyor belt so that the limit groove 14 can adapt to the length of the paper core. Adjust the height of the support feet to ensure that the support frame 1 is in a horizontal state and ensure the stability of the device operation. Then, place the paper cores to be processed one by one into the limiting groove 14 of the conveying mechanism 11. Under the constraint of the limiting groove 14, the paper cores will not roll or shift. The operator issues a start command on the control system 13 to control the conveying mechanism 11 to move, thereby driving the paper cores placed in the limiting groove 14 to be transported forward. Then, when the paper core is transported to the working area of the fixed mechanism 2 by the conveyor belt, the infrared sensor 26 at the upper end of the push plate 25 detects the paper core. The infrared sensor 26 adopts a diffuse reflection design, which can accurately detect whether the paper core has reached the designated position and can quickly transmit the detection signal to the control system 13. At this moment, after receiving the signal from the infrared sensor 26, the control system 13 immediately sends a pause command to the conveying mechanism 11, the drive motor stops working, the conveyor belt stops conveying, and the paper core stops accurately at the positioning position. At the same time, the control system 13 sends an extension command to the telescopic rod 24. The piston rod of the telescopic rod 24 extends outward under the action of compressed air, pushing the push plate 25 to move towards the paper core. During the movement of the push plate 25, the smoothness of the push plate 25 is ensured. The push plate 25 drives the arc-shaped frame plate 22 to move synchronously. The protective pad 28 on the inner wall of the arc-shaped frame plate 22 first contacts the surface of the paper core. As the telescopic rod 24 continues to extend, the two sets of arc-shaped frame plates 22 clamp the paper core from both sides. Finally, after the paper core is positioned, external processing equipment (such as cutting and grinding equipment) performs processing operations on the paper core. During the processing, since the paper core is firmly positioned and the conveyor belt is in a stopped state, the processing accuracy and quality are guaranteed. At the same time, the control system 13 monitors the signal of the magnetic switch on the telescopic rod 24 in real time, grasps the extension and retraction position of the piston rod, and ensures that the clamping state of the arc frame plate 22 on the paper core is stable. After the paper core is processed, the external processing equipment sends a processing completion signal to the control system 13. The control system 13 then sends a retraction command to the telescopic rod 24. The piston rod drives the push plate 25 and the arc-shaped frame plate 22 to move away from the paper core, releasing the clamping of the paper core. When the telescopic rod 24 is fully retracted, the magnetic switch sends a signal back to the control system 13. The control system 13 sends a start command to the drive motor, and the conveying mechanism 11 starts working again, transferring the processed paper core to the next process. At the same time, the paper cores to be processed continue to enter the working area of the fixing mechanism 2, repeating the above positioning and processing process to achieve continuous production.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
