Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting equipment, in particular to a raw material feeding positioning and deviation correction structure. Background Art

[0002] The rotary die cutting machine is also called the rotary machine, commonly known as the rotary die cutting machine, the roller cutter or the multi-station rotary die cutting machine. It continuously rotates and cuts in the form of a roller, and is one of the most efficient equipment among the die cutting machines. The die-cut products are widely used in mobile phones, computers, LCD monitors, digital cameras, LCD backlights and other fields.

[0003] At present, circular knife die-cutting machines are equipped with matching material shafts. The rolled raw materials are installed on the material shafts, which are unwound by the material shafts and then transported to subsequent processing sites for processing by guide rollers. When the material roll is installed on the material shaft, the Y-axis positioning of the material roll during installation is controlled only by checking the scale on the unwinding shaft. The operation is time-consuming and labor-intensive, and the positioning accuracy of the material roll installed on the unwinding shaft is not high. In addition, since the side alignment of the raw material is not aligned when it is rolled into a roll, the unwound raw material is prone to Y-axis deviation during the transportation process, resulting in the raw material being unable to be accurately positioned when entering the subsequent processing station, affecting the processing quality. Utility Model Content

[0004] The purpose of the utility model is to provide a raw material feeding positioning and correction structure, which solves the problem that the raw material cannot be accurately positioned and will have Y-axis deviation when it is unwound from the material shaft and enters the subsequent processing station, thereby affecting the processing quality. It has a compact structure and a high degree of automation, and can quickly and accurately position and adjust the Y-axis position of the raw material, thereby improving the product processing quality.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides a raw material feeding positioning and deviation correction structure, comprising a base, a material discharge shaft, a positioning component, a deviation correction drive component, a deviation correction sensor and a deviation correction controller;

[0007] The front side of the base is provided with the unloading shaft, which adopts an air-expanding shaft to facilitate loading and unloading of the material roll. The outer side of the unloading shaft is provided with a positioning component which cooperates with the side surface of one side of the raw material roll and positions the raw material roll along the axial direction of the unloading shaft (that is, the Y direction);

[0008] A deflection correction sensor with an adjustable position for detecting changes in the edge position of the raw material is installed on the base. The deflection correction sensor is located close to the next workstation. The deflection correction sensor is connected to the deflection correction controller signal, and the deflection correction controller is connected to the deflection correction drive assembly. The deflection correction drive assembly is connected to the discharge shaft for driving the discharge shaft to move along its axial direction.

[0009] Furthermore, the positioning assembly and the deviation correction sensor can both be adjusted in position along the axial direction of the unloading shaft.

[0010] In actual application, the installation position of the positioning component can be adjusted according to the actual processing needs and the specifications of the material coil, so as to adjust the position of the material coil installed on the unwinding shaft; correspondingly, the installation position of the correction sensor can be adjusted according to the adaptability of the installation position of the material coil to ensure that the edge position of the unrolled raw material can just pass through the correction sensor.

[0011] Furthermore, the deviation correction sensor is installed on a mounting plate, a linear drive assembly is provided at the bottom of the mounting plate, the linear drive assembly is installed on a base, and the linear drive assembly drives the mounting plate to adjust its position along the axial direction of the discharge axis.

[0012] When material rolls of different specifications are installed on the unwinding shaft, the Y-axis installation position needs to be adjusted accordingly. At this time, the linear drive component drives the correction sensor on the mounting plate to move along the axial direction of the unwinding shaft. The position of the correction sensor can be adjusted accordingly to ensure that the edge of the unrolled raw material can just pass through the correction sensor, thereby ensuring the normal operation of the automatic correction operation of the material roll in the Y direction.

[0013] Specifically, a detection slot for the edge of the raw material to pass through is opened on the mounting plate, and the correction sensor is installed on the inner wall of the detection slot. The linear drive component can adopt a structural component with linear movement function in the prior art, such as a structure that can adopt a guide rail, a slider and an adjustment bolt.

[0014] Furthermore, the correction drive assembly includes a correction motor, a synchronous belt transmission assembly, a connecting plate and a screw assembly. The correction motor is installed on a base, and its driving end is connected to the synchronous belt transmission assembly. The output end of the synchronous belt transmission assembly is connected to the screw assembly, and the screw assembly is connected to a connecting plate, and the discharge shaft is installed on the connecting plate.

[0015] When working, the correction motor receives the signal and drives the screw assembly through the synchronous belt transmission assembly. The screw assembly drives the connecting plate to move, and then drives the unloading shaft located on the connecting plate to move along its axial direction, thereby realizing automatic and precise adjustment of the Y-axis position of the material roll on the unloading shaft.

[0016] Furthermore, the end of the discharge shaft is rotatably mounted on the connecting plate, and the end of the discharge shaft is drivingly connected to a discharge driving assembly.

[0017] The unloading drive assembly drives the unloading shaft to rotate, thereby achieving the purpose of automatically unwinding the raw material at a uniform speed. Specifically, the unloading drive assembly can select a transmission structure in which a motor and a synchronous pulley cooperate with each other in the prior art.

[0018] Furthermore, the positioning assembly includes a plurality of limit blocks, locking pieces and a material stop plate. A plurality of groups of adjustment holes are provided on the outer side of the discharge shaft along the circumferential direction. Each group of adjustment holes includes a plurality of adjustment holes evenly distributed along the axial direction of the outer side of the discharge shaft. The plurality of limit blocks are distributed in the circumferential direction of the outer side of the discharge shaft, and positioning holes are provided on the limit blocks. The locking pieces pass through the positioning holes and the adjustment holes correspondingly. The material stop plate is sleeved on the outer side of the discharge shaft, and one side of the limit block is fitted with the end of the limit block.

[0019] Previously, when placing the material roll on the unwinding shaft, the Y-axis positioning of the material roll during installation was controlled manually by checking the ruler on the outside of the unwinding shaft. The above operation was time-consuming and laborious, and the positioning accuracy of the material roll installed on the unwinding shaft was not high. By setting multiple limit blocks in the circumferential direction of the outside of the unwinding shaft, the limit blocks are fixed to the outside of the unwinding shaft by locking parts, and the installation position of the limit blocks can be adjusted, so as to adjust the position of the stop plate installed with the limit blocks. When loading, only one side of the material roll needs to be aligned with the end of the unwinding shaft, and the material roll is pushed inward. The material roll is sleeved on the outside of the unwinding shaft and moves inward until one side of the material roll is in close contact with the stop plate. The loading operation of the material roll is completed, which is convenient for workers to operate the loading operation and can accurately position the material roll in the Y direction.

[0020] Furthermore, the positioning hole is a waist-shaped hole, and the adjustment hole is arranged on the outer side of the end of the discharge shaft away from the free end.

[0021] The waist-shaped positioning hole is adopted, and the installation position adjustment range of the limit block and the material stop plate is further expanded, which is convenient for continuous adjustment and precise positioning of the installation position of the material roll.

[0022] Furthermore, a first material guide roller and a second material guide roller installed on a base are provided next to the deflection correction sensor. The first material guide roller guides the raw material unwound from the unwinding shaft to the deflection correction sensor, and the second material guide roller guides the raw material after being detected and position-corrected by the deflection correction sensor. The second material guide roller is located close to the next processing site.

[0023] The raw material unwound by the unwinding shaft is guided to the correction sensor via the first guide roller. With the cooperation of the correction controller and the correction drive assembly, the Y-position of the unwound raw material is timely, automatically and accurately adjusted. The raw material with adjusted Y-position is conveyed to the next processing site via the second guide roller for subsequent processing.

[0024] Furthermore, the first material guide roller, the second material guide roller and the unwinding shaft are arranged in parallel, and the first material guide roller and the second material guide roller are both unpowered material guide rollers.

[0025] The unpowered guide roller is used to guide and convey the unwound raw material, realizing the guiding function, and the conveying is smooth and fast, and more economical.

[0026] Furthermore, the second material guide roller is provided with a limiting member that cooperates with two side edges of the raw material for positioning, and the distance between the two limiting members can be adjusted.

[0027] In order to further ensure that the raw material will not deviate in the Y direction when entering the subsequent processing station, the two limiters on the second guide roller are used to position the raw material in the Y direction after the correction treatment, and the distance between the two limiters can be adaptively adjusted according to the installation position and specifications of the coil on the unwinding shaft.

[0028] Furthermore, the limiting member is a limiting ring, a notch is provided on one side of the limiting ring, and the limiting ring is sleeved on the outer side of the second material guide roller.

[0029] In order to facilitate the adjustment of the position of the limit piece, a ruler is provided on the second guide roller. Through the notch on the limit ring, workers apply external force to the limit ring to drive it to move along the outer side of the second guide roller to a specific position.

[0030] Compared with the prior art, the utility model has the following beneficial effects:

[0031] In the utility model, the position of the material coil installed on the unwinding shaft is accurately positioned in the Y direction through the positioning component, the Y-direction position information of the unwinding raw material is detected by the deflection correction sensor, and the information is transmitted to the deflection correction controller, and then the deflection correction controller sends a signal to the deflection correction drive component, and the unwinding shaft is driven to move along its axial direction by the deflection correction drive component, thereby realizing timely, automatic and accurate adjustment of the Y-direction position of the unwinding raw material; the deflection correction sensor is arranged close to the next work station, and the raw material after deflection correction can be transported to the next work station for subsequent processing via a shorter transmission distance, thereby avoiding the Y-direction deviation of the raw material after deflection correction again; the positioning and deflection correction structure has a high degree of automation and a compact structure, and can quickly and accurately position and adjust the Y-direction position of the raw material, thereby improving the product processing quality.

The positioning and correcting structure has a high degree of automation and a compact structure, and can quickly and accurately position and adjust the Y-direction position of the raw material, thereby improving the processing quality of the product.

[0043] Among them, Figure 2 and Figure 3As shown, the positioning assembly includes a plurality of limit blocks 4, locking parts and a material stopper plate 5. The outer side of the unloading shaft 2 is provided with a plurality of groups of adjustment holes along the circumferential direction.
