Description

Technical Field

[0001] The utility model relates to a paper inserting machine component of a winding mechanism, and more specifically, to an insulating paper inserting mechanism for preventing paper jams. Background Art

[0002] During the process of processing stator coils, it is necessary to insert the insulating paper into the stator coils through a paper inserting machine. When inserting the insulating paper, due to the low hardness of the insulating paper itself, the insulating paper will fold inside the paper inserting mechanism during the insertion process, resulting in blockage of the paper inserting mechanism. If the paper inserting machine cannot stop automatically at this time, the insulating paper cannot be inserted into the stator coils, causing waste of resources and reducing the overall production and processing efficiency. At the same time, the paper inserting mechanism is usually non-detachable. After blockage occurs inside, usually, the insulating paper can only be pulled out from the gap at the insertion end. If it breaks during the pulling process, it will increase the difficulty of cleaning and reduce the service life of the device.

[0003] Currently, most of the paper inserting mechanisms on the market do not have the function of detecting whether the paper inserting mechanism is blocked. Usually, workers need to judge with the naked eye, which increases the workload of the workers and cannot obtain the working state of the equipment in time and stop the equipment in time, easily causing waste of resources and reducing the qualification rate of stator coil production. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide an insulating paper inserting mechanism for preventing paper jams with a simple structure, high automation degree, which can automatically judge whether the device is blocked during the process of pushing the paper and control the device.

[0005] To achieve the above purpose, the present utility model provides the following technical solutions: An insulating paper inserting mechanism for preventing paper jams, including a mounting plate, a pressing plate is provided on the mounting plate, a sliding groove is opened on the pressing plate, a paper pushing protection block is provided on the sliding groove, the paper pushing protection block slides in the sliding groove, a paper pushing connecting block is further provided on the paper pushing protection block, the paper pushing connecting block is configured to be in contact with the insulating paper and push the sliding of the paper pushing protection block, one end of the pressing plate is provided with a mounting seat, the mounting seat is bolted to the pressing plate and forms a gap for passing the insulating paper with the paper pushing protection block, a return spring is provided between the mounting seat and the paper pushing protection block, and an induction plate is provided at the other end of the pressing plate, and the induction plate is used for detecting the blockage state of the insulating paper.

[0006] The present utility model is further provided as: a first spring pin is provided on the mounting seat, a second spring pin is provided on the paper pushing protection block, and the first spring pin and the second spring pin are located on the same straight line.

[0007] The present utility model is further configured as follows: a placement groove for installing a paper-pushing connection block is further provided in the middle of the pressing plate, and an installation groove matching the paper-pushing connection block is provided in the middle of the paper-pushing protection block.

[0008] Preferably, the length of the sliding groove > the length of the paper-pushing protection block, the length of the placement groove > the length of the paper-pushing connection block, and the length of the sliding groove - the length of the paper-pushing protection block = the length of the placement groove - the length of the paper-pushing connection block.

[0009] Preferably, the gap between the sliding groove and the paper-pushing protection block and the gap between the placement groove and the paper-pushing connection block are set to be 5 mm - 8 mm.

[0010] The present utility model is further configured as follows: a pressure sensor is provided on the induction plate, and the pressure sensor is used to detect the pressure signal of the induction plate and control the operating state of the paper-inserting mechanism.

[0011] The present utility model is further configured as follows: the mounting seat, the pressing plate, and the mounting plate are fixedly connected by bolts, and the paper-pushing connection block and the paper-pushing protection block are fixedly connected by bolts.

[0012] By adopting the above technical solutions, the beneficial effects are as follows: 1. The mounting seat is arranged at the upper end of the pressing plate and forms a gap for preventing insulating paper with the paper-pushing protection block. The insulating paper is arranged in the gap and abuts against the paper-pushing connection block arranged on the paper-pushing protection block, and the insulating paper is inserted. At the same time, a gap is provided between the paper-pushing protection block and the pressing plate. When the device is blocked, the insulating paper accumulates in the gap, and at the same time, the paper-pushing protection block moves backward. When the paper-pushing protection block contacts the induction plate, it is determined that the inside of the device is blocked, and the device stops running. The overall automation degree is high, and it can effectively prevent the accumulation and blockage of insulating paper.

[0013] 2. The paper-pushing protection block slides inside the pressing plate, and a return spring is provided between the paper-pushing protection block and the pressing plate, so that the paper-pushing protection block can slide towards the induction plate after paper jamming, and can automatically reset after the paper jam in the gap is cleared. The automation degree is high. At the same time, the length of the sliding groove > the length of the paper-pushing protection block, the length of the placement groove > the length of the paper-pushing connection block, and the length of the sliding groove - the length of the paper-pushing protection block = the length of the placement groove - the length of the paper-pushing connection block, and the width of the paper-pushing connection block > the width of the sliding groove. After the device slides, the paper-pushing connection block can timely abut against both ends of the sliding groove, so that the sliding distance of the paper-pushing protection block is fixed. After the paper-inserting mechanism is blocked, the induction plate can respond in time and stop the device from running, effectively preventing waste of resources.

[0014] 3. The paper inserting mechanism is arranged below the whole paper inserting machine and is connected to the element to be processed through a push rod. During the normal operation of the device, that is, the insulating paper slides smoothly in the gap between the paper pushing protection block and the pressing plate, the pressure on the paper pushing protection block is small, and the paper pushing action of the device runs smoothly. When the paper inserting mechanism gets jammed, the resistance on the push rod becomes larger. At the same time, the pressing plate keeps the tendency of moving upward. At this time, the paper pushing protection block and the paper pushing connection block inside the pressing plate remain relatively stationary under the action of the push rod. Taking the pressing plate as a reference, the paper pushing connection block slides backward inside the pressing plate and approaches the induction plate. When the paper pushing connection block contacts the induction plate, it is judged that there is a paper jam, and the device stops automatically. By setting a pressure sensor to replace manual detection, it can make a timely reaction after the paper jam and prevent the waste of insulating paper.

[0015] 4. The gap between the chute and the paper pushing protection block and the gap between the placement groove and the paper pushing connection block are set to be 5 mm - 8 mm. That is, after the paper pushing protection block needs to move 5 mm - 8 mm, it is judged that there is a paper jam. If the set gap is less than 5 mm, due to the relatively high strength of the insulating paper body, during the paper pushing process, the paper pushing protection block will inevitably slide towards the induction plate. If the set gap is too small, it is easy to cause misjudgment of the device, resulting in unnecessary stoppage of the equipment and reducing the production efficiency. If the gap is set to be greater than 8 mm, it will be difficult for the paper pushing protection block to contact the induction plate, causing waste of resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The mounting seat 6, the pressing plate 2 and the mounting plate 1 are fixedly connected by bolts, and the paper pushing connecting block 5 and the paper pushing protection block 4 are fixedly connected by bolts.

[0024] The mounting seat 6 is arranged at the upper end of the pressing plate 2 and forms a gap for preventing the insulating paper with the paper pushing protection block 4, the insulating paper is arranged in the gap and is in contact with the paper pushing connecting block 5 arranged on the paper pushing protection block 4 to perform the insertion operation on the insulating paper. At the same time, a gap is provided between the paper pushing protection block 4 and the pressing plate 2. After the device is blocked, the insulating paper accumulates in the gap, and at the same time, the paper pushing protection block 4 moves backward. When the paper pushing protection block 4 contacts the induction plate 8, it is determined that the inside of the device is blocked, and the device stops running. The overall automation degree is high, and the accumulation and blockage of the insulating paper can be effectively prevented.

[0025] Further, a first spring pin 9 is provided on the mounting base 6, and a second spring pin 10 is provided on the paper pushing protection block 4. The first spring pin 9 and the second spring pin 10 are located on the same straight line.

[0026] A placement groove 11 for installing the paper pushing connection block 5 is further provided in the middle of the pressing plate 2, and an installation groove 12 matching the paper pushing connection block 5 is provided in the middle of the paper pushing protection block 4.

[0027] Preferably, the length of the sliding groove 3 > the length of the paper pushing protection block 4, the length of the placement groove 11 > the length of the paper pushing connection block 5, and the length of the sliding groove 3 - the length of the paper pushing protection block 4 = the length of the placement groove 11 - the length of the paper pushing connection block 5.

[0028] Preferably, the gap between the sliding groove 3 and the paper pushing protection block 4 and the gap between the placement groove 11 and the paper pushing connection block 5 are set to 5 mm - 8 mm.

[0029] The paper pushing protection block 4 slides inside the pressing plate 2, and a return spring 7 is provided between the paper pushing protection block 4 and the pressing plate 2, so that the paper pushing protection block 4 can slide towards the induction plate 8 after paper jamming, and can automatically reset after the paper jam in the gap is cleared. The degree of automation is high. At the same time, the length of the sliding groove 3 > the length of the paper pushing protection block 4, the length of the placement groove 11 > the length of the paper pushing connection block 5, and the length of the sliding groove 3 - the length of the paper pushing protection block 4 = the length of the placement groove 11 - the length of the paper pushing connection block 5, and the width of the paper pushing connection block 5 > the width of the sliding groove 3.

If the set gap is less than 5 mm, due to the high strength of the insulating paper body, during the paper pushing process, the paper pushing protection block 4 will inevitably slide towards the induction plate 8. If the set gap is too small, it is easy to cause misjudgment of the device, resulting in unnecessary stoppage of the equipment and reducing production efficiency. If the gap is set greater than 8 mm, it will be difficult for the paper pushing protection block 4 to contact the induction plate 8, causing waste of resources.

[0031] Moreover, a pressure sensor is provided on the induction plate 8, and the pressure sensor is used to detect the pressure signal of the induction plate 8 and control the operating state of the paper inserting mechanism.

[0032] The described paper inserting mechanism is arranged below the whole paper inserting machine and is connected to the element to be processed through a push rod. During the normal operation of the device, that is, the insulating paper slides smoothly in the gap between the paper pushing protection block 4 and the pressing plate 2, the pressure received by the paper pushing protection block 4 is small, and the paper pushing action of the device runs smoothly. When paper jamming occurs in the paper inserting mechanism, the resistance received by the push rod becomes larger. At the same time, the pressing plate 2 maintains an upward running trend. At this time, the paper pushing protection block 4 and the paper pushing connecting block 5 inside the pressing plate 2 remain relatively stationary within the pressing plate 2 under the action of the push rod. Taking the pressing plate 2 as a reference, the paper pushing connecting block 5 slides backward inside the pressing plate 2 and approaches the induction plate 8. When the paper pushing connecting block 5 contacts the induction plate 8, it is judged that paper jamming occurs, and the device stops automatically. By setting a pressure sensor to replace manual detection, it can make a timely reaction after paper jamming and prevent waste of insulating paper.
