Description

Technical Field

[0001] This utility model relates to the field of stator manufacturing technology, specifically to a stator paper feeding system and its paper-printing mechanism. Background Technology

[0002] In the stator processing production line, the stator needs to go through processes such as paper insertion, winding, wire embedding, shaping, and wire binding. Before wire embedding, slot cover paper is usually inserted into the wire embedding mold. The insertion process involves paper feeding, paper cutting, and paper punching.

[0003] In existing technologies, during the paper feeding process, especially when the paper strip is near the paper-pressing mechanism, if the paper-pressing or paper-feeding mechanism malfunctions, the paper belt will often break, causing the equipment to stop and the paper belt to be replaced, which wastes a lot of time. To address this, a stator paper feeding system and its paper-pressing mechanism are designed. Utility Model Content

[0004] The purpose of this utility model is to provide a stator paper feeding system and its paper-printing mechanism. By setting a pre-feeding module and cooperating with a photoelectric sensor, the paper strip is always kept at a distance between the pre-feeding module and the paper feeding roller module. Through this loose paper strip, it is possible to effectively avoid the paper strip being accidentally pulled or broken in subsequent paper-printing steps.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stator paper feeding system, comprising: a paper tape reel, a paper detection module, a pre-feed module, and a paper feed roller module; the paper tape reel releases paper strips that sequentially pass through the paper detection module, the pre-feed module, and the paper feed roller module, leaving a distance between the pre-feed module and the paper feed roller module; the pre-feed module includes a mounting box, and an infeed roller assembly and an outfeed roller assembly disposed on the mounting box, and a first guide strip, a second guide strip, and a third guide strip are sequentially arranged between the infeed roller assembly and the outfeed roller assembly; the mounting box also has a first photoelectric sensor and a second photoelectric sensor disposed opposite to each other, the first photoelectric sensor acting on the inside of the mounting box to detect the paper strip at the position of the second guide strip, and the second photoelectric sensor acting on the outside of the mounting box to detect the paper strip left at a distance.

[0006] Preferably, the paper feed roller assembly includes a first servo motor, the output end of the first servo motor passing through the through hole where the first servo motor is located and a first conveying roller is fixed thereon, and a mounting component assembled on the mounting box, on which a rotatable second conveying roller is mounted.

[0007] Preferably, the paper output roller assembly includes two sets of paper output rollers that can rotate relative to each other, and the third guide strip is located below the rear side of the paper output rollers.

[0008] Preferably, the paper detection module includes an assembly, a limit switch and a fourth conveying roller respectively disposed on the upper and lower parts of the assembly, the gap formed by the limit switch and the fourth conveying roller is used for paper strips to pass through, and the limit switch can issue an alarm when there is no paper.

[0009] Preferably, the paper feeding roller module includes a connecting plate and a guide plate fixed on the connecting plate and placed at an angle. The upper surface of the guide plate is provided with a paper guide groove for the paper strip to pass through, and a pressure roller is provided at the lower end of the guide plate for flattening the paper strip when it moves forward.

[0010] Preferably, a second servo motor is also fixedly mounted on the side wall of the connecting plate. The output end of the second servo motor passes through the connecting plate and is fixed with a drive wheel, as well as a bottom wheel that can rotate in the middle of the guide plate. The gap formed between the bottom wheel and the drive wheel is used for the paper strip to pass through.

[0011] A stator paper-pressing mechanism includes a stator paper-feeding system as described above; and a stator paper-pressing mechanism assembled with the stator paper-feeding system, wherein the stator paper-pressing mechanism is provided with a frame for assembling the stator paper-feeding system.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, through the design of a pre-feeding module, ensures that a distance is maintained between the pre-feeding module and the paper feeding roller module. In conjunction with a second photoelectric sensor, this distance is maintained on the paper strip. If this section of paper is used up and straightened, the second photoelectric sensor receives this signal, driving the paper feeding roller assembly to operate. This ensures that a certain distance of paper strip is always maintained at the position of the second photoelectric sensor. This relaxed section of paper strip effectively prevents accidental pulling, breakage, or other unexpected situations from occurring during subsequent paper printing steps.

[0024] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Please see Figures 1 to 6The present invention preferably provides the following technical solution: a stator paper feeding system, comprising: a paper tape reel 11, a paper detection module 14, a pre-feed module 12, and a paper feed roller module 13; the paper tape reel 11 releases paper strips that sequentially pass through the paper detection module 14, the pre-feed module 12, and the paper feed roller module 13, leaving a distance between the pre-feed module 12 and the paper feed roller module 13; the pre-feed module 12 includes a mounting box 121, and an infeed roller assembly and an outfeed roller assembly disposed on the mounting box 121, and a first guide strip 125, a second guide strip 126, and a third guide strip 129 are sequentially arranged between the infeed roller assembly and the outfeed roller assembly; a first photoelectric sensor 127 and a second photoelectric sensor 128 are also disposed opposite to each other on the mounting box 121, the first photoelectric sensor 127 acts on the inside of the mounting box 121 to detect the paper strip at the position of the second guide strip 126, and the second photoelectric sensor 128 acts on the outside of the mounting box 121 to detect the paper strip left at a distance.

[0027] like Figure 1 As shown, a paper feeding system for stator paper output is provided, which adds a paper detection module 14 and a pre-feed module 12. The paper detection module 14 can detect the presence or absence of paper strips, and can promptly issue an alarm when the paper strips are used up. The pre-feed module 12 is designed such that... Figure 1 , 3 As shown in Figure 6, the paper tape reel 11 can release paper strips that pass sequentially through the paper detection module 14, the pre-feed module 12, and the paper feed roller module 13, leaving a distance between the pre-feed module 12 and the paper feed roller module 13. The first photoelectric sensor 127 inside the mounting box 121 can detect the paper strip conveying status on the second guide strip 126. The power for paper feeding is provided by the paper feed roller assembly. The second photoelectric sensor 128 externally mounted on the mounting box 121 acts on the paper strip position where a distance is left. The first photoelectric sensor 127 and the second photoelectric sensor 128 are existing mature technologies. When an object passes through and cuts the light, a signal is output.

[0028] When the paper strip is used up and straightened, the corresponding second photoelectric sensor 128 receives this signal and drives the paper feed roller assembly to work, thereby ensuring that there is always a piece of paper strip at the position of the second photoelectric sensor 128. Through this loose paper strip, it is possible to effectively avoid the paper strip being accidentally pulled or broken in subsequent paper printing steps.

[0029] Furthermore, the paper feed roller assembly includes a first servo motor 122, the output end of the first servo motor 122 passes through the through hole where the first servo motor 122 is located and a first conveyor roller 123 is fixed thereon, and a mounting component 1211 is assembled on the mounting box 121, on which a rotatable second conveyor roller 124 is mounted.

[0030] Furthermore, the paper output roller assembly includes two sets of paper output rollers 1210 that can rotate relative to each other, and a third guide bar 129 is located below the rear side of the paper output rollers 1210.

[0031] like Figure 3 As shown, the paper feed roller assembly is designed to act as a separate driving force to control the paper strip's forward movement. It is controlled by the second photoelectric sensor 128 and the first photoelectric sensor 127 for the pre-feeding of the paper strip, thereby maintaining a certain distance between the paper strip and the position of the second photoelectric sensor 128.

[0032] Example 2

[0033] In another embodiment of this utility model, the paper detection module 14 includes an assembly 142, a limit switch 143 and a fourth conveying roller 141 respectively disposed on the upper and lower parts of the assembly 142. The gap formed by the limit switch 143 and the fourth conveying roller 141 is used for paper strips to pass through. The limit switch 143 can issue an alarm when there is no paper.

[0034] In this embodiment, a paper detection module 14 is provided. The limit switch 143 is a mature existing technology and a commonly used low-current control electrical appliance. It utilizes the movement of moving parts in the production machinery to actuate its contacts, thereby connecting or disconnecting the control circuit. Figure 5 As shown, the paper strip can pass between the fourth conveyor roller 141 and the limit switch 143. When the paper strip is used up, the limit switch 143 loses the restriction of the paper strip and is displaced, thereby triggering the paper-out signal and sending the signal to the controller. The controller then controls and stops the machine in time.

[0035] Example 3

[0036] In another embodiment of the present invention, the paper feeding roller module 13 includes a connecting plate 133 and a guide plate 131 fixed on the connecting plate 133 and placed at an angle. The upper surface of the guide plate 131 is provided with a paper guide groove 135 for the paper strip to pass through, and a pressure roller 137 is provided at the lower end of the guide plate 131 for flattening the paper strip when it moves forward.

[0037] Furthermore, a second servo motor 134 is fixedly mounted on the side wall of the connecting plate 133. The output end of the second servo motor 134 passes through the connecting plate 133 and is fixed with a drive wheel 136, as well as a bottom wheel 132 that can rotate in the middle of the guide plate 131. The gap formed between the bottom wheel 132 and the drive wheel 136 is used for the paper strip to pass through.

[0038] like Figure 4As shown, a paper feeding roller module 13 structure is provided. The guide plate 131 is inclined to facilitate the feeding of paper strips. The pressure roller 137 can flatten the paper strips. When the second servo motor 134 is working, it can drive the drive wheel 136 to rotate. Through the interaction between the drive wheel 136 and the bottom wheel 132, the paper strips can be fed in an orderly and stable manner in the paper guide groove 135.

[0041] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part. Among these, there are various ways to install detachably, such as by using a combination of plug-in and snap-fit, or by using bolts for connection, etc.

[0042] In addition, all the connections / connections mentioned in the article do not refer to direct connection of components, but rather to the formation of a better connection structure by adding or removing connecting accessories according to the specific implementation situation.
