Description

Technical Field

[0001] The invention relates to a flanging and paper inserting machine, belonging to the technical field of new energy motor processing. Background Art

[0002] Currently, the coils inside new energy motor stators are insulated from the paper slots by insulating paper. This paper must be pre-inserted into the stator before the coils are inserted into the slots. Currently, inserting the insulating paper into the slots requires folding the paper into a specific shape that matches the slots. This shape then wraps around the coils, insulating them from the slot walls.

[0003] However, when the formed insulating paper is inserted, the insulating paper may be easily deformed or cannot be inserted to the correct position due to inaccurate stroke control, which affects the quality of paper insertion and causes insulation failure between the coil and the stator.

[0004] In view of the above-mentioned defects, the present invention aims to create a flanging and inserting paper machine to make it more valuable in industrial application. Summary of the Invention

[0017] The paper-folding forming mechanism comprises a cutting cylinder, a paper-folding cylinder, and a downward-pressing fixed cylinder arranged side by side. The output end of the cutting cylinder is connected to a cutting blade for cutting the paper strip to a preset length. The bottom of the paper-folding cylinder is fixedly connected to a paper-folding pressing piece for pressing the cut paper strip into the paper-folding groove to fold it into a pre-formed shape. The bottom of the downward-pressing fixed cylinder is fixedly connected to a downward-pressing fixed block for pressing one end of the paper strip when cutting to prevent the paper strip from shifting and affecting the cutting size.

[0018] Furthermore, the paper insertion slot includes an origami forming base located at the bottom, and a right folding mold and a left folding mold are respectively provided on both sides of the top of the origami forming base.

Figure 16 Finished paper strips;

[0020] Furthermore, the folding channel includes a folding channel for folding and shaping the paper strip to be processed. The top of the folding channel is provided with folding entrance guide slopes on both sides, which serve as a guide when the folding press sheet presses the paper strip to be processed into the folding channel. The top of the folding channel is provided with a cutting groove and a downward pressing fixing groove on both sides, which match the positions of the cutting blade and the downward pressing fixing block, respectively, for cutting and fixing the edges of the paper strip to be processed. A flanging channel is also provided on the top of the cutting groove and the downward pressing fixing groove. It is used to pass the protruding part of the flanging of the paper strip to be processed in the previous process.

[0021] Furthermore, the flanging and inserting paper machine also includes a cache mechanism, which is arranged at the rear side of the paper feeding drive mechanism and includes a cache fixing plate. A cache slide rail is fixedly installed on the surface of the cache fixing plate in the vertical direction, and a cache slider is slidably sleeved on the surface of the cache slide rail. A cache suspension rod is provided at the front end of the cache slider in the horizontal direction, and the cache suspension rod includes two long rods parallel to each other, with a gap between the two long rods to ensure that the paper strip to be processed passes through. The top of the cache slider is suspended on the top of the cache slide rail by a buffer spring, and a sensor mounting plate is fixedly installed on the side edge of the cache fixing plate. An upper sensor and a lower sensor are fixedly installed at the upper and lower ends of the sensor mounting plate respectively, and the upper sensor and the lower sensor are both signal-connected to the paper feeding drive mechanism. In actual work, if there is no need to feed paper to the subsequent process, the cache hanger is not supported by the tensioning force of the paper strip to be processed. At this time, the cache slider will fall downward under the action of gravity. When it falls to the lower sensor, the sensor will be triggered. At this time, the lower sensor transmits a signal to the paper feeding drive mechanism to stop feeding paper, thereby restoring the tensioning force of the paper strip to be processed. Under the action of the tensioning force of the paper strip to be processed, the cache hanger and the cache slider will be driven to move upward until they reach the upper sensor. At this time, it indicates that the paper strip to be processed is over-tightened and needs to continue feeding paper. Therefore, the upper sensor will continue to transmit the sensing signal back to the paper feeding drive mechanism to prompt it to continue feeding paper.

[0022] Furthermore, the indexing rotation mechanism is arranged on the outlet side of the cutting and pushing paper mechanism, and includes an indexing mounting plate, a indexing rotation motor is fixedly mounted on the back of the indexing mounting plate, and the output end of the indexing rotation motor is transmission-connected to the stator fixing plate, and the stator fixing plate is located on the front of the indexing mounting plate;

[0025] Furthermore, a paper feeding servo mechanism is provided at the rear side of the preforming mechanism. The paper feeding servo mechanism includes a paper feeding motor mounting seat, on which a paper feeding motor is fixedly mounted. The output end of the paper feeding motor is connected to a paper feeding screw, on the surface of which a paper feeding screw slider is connected in a transmission sleeve. A paper feeding mounting plate is connected to one side of the paper feeding screw slider. A paper feeding base is fixedly provided on the upper surface of the paper feeding mounting plate. A pressure block cylinder mounting frame is provided above the paper feeding base. A pressure block cylinder is fixedly mounted on the top surface of the pressure block cylinder mounting frame. The output end of the pressure block cylinder is connected to a paper feeding pressure block. The paper feeding pressure block and the paper feeding base are matched with each other. A paper feeding strip channel is formed between the two. After the paper strip to be processed after the previous chamfering and indentation is processed and enters the paper feeding strip channel, it is clamped by the paper feeding pressure block and the paper feeding base and transported to the next process for further processing under the drive of the paper feeding motor.

[0026] Furthermore, a guide mechanism is provided behind the buffer mechanism. The guide mechanism comprises a transversely mounted guide bar with a guide pressure plate fixedly mounted on its surface via two mounting rings. The distance between the two mounting rings is greater than the width of the paper strip to be processed, and the distance between the guide bar and the guide pressure plate is greater than the thickness of the paper strip to be processed. By passing the paper strip between the guide bar and the guide pressure plate and being restrained by the two mounting rings, the paper strip to be processed is conveyed flat and correctly toward the next process.

[0027] Furthermore, the paper feed drive mechanism includes a paper strip guide rod, and a paper feed drive roller is mounted behind the paper strip guide rod. A paper feed auxiliary roller is arranged parallel to the bottom of the paper feed drive roller, and one end of the paper feed drive roller is connected to the output end of the paper feed drive motor.

[0085] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0086] See also Figure 1A preferred embodiment of the present invention provides a flanging and inserting paper machine, comprising a working platform 1, a paper feeding drive mechanism 2 being provided on the front end of the working platform 1, a chamfering mechanism 5, a longitudinal indentation mechanism 6, a transverse indentation mechanism 7, a preforming mechanism 8, a cutting and pushing mechanism 10, and an indexing and rotating mechanism 11 being provided in sequence behind the paper feeding drive mechanism 2;

[0087] See also Figure 2 The paper feeding drive mechanism 2 includes a paper strip guide rod 21 for guiding and tightening the paper strip 12 to be processed; a paper feeding drive roller 22 is also provided behind the paper strip guide rod 21, and a paper feeding auxiliary roller 23 is provided at the bottom of the paper feeding drive roller 22 in parallel therewith. One end of the paper feeding drive roller 22 is transmission-connected to the output end of the paper feeding drive motor 24. The paper feeding drive roller 22 is driven to rotate by the paper feeding drive motor 24, and the squeezing friction of the paper feeding auxiliary roller 23 is combined with the paper strip 12 to be processed to move to the next process;

[0088] See also Figure 3 The flanging and inserting paper machine also includes a cache mechanism 3, which is arranged at the rear side of the paper feeding drive mechanism 2, including a cache fixing plate 31, a cache slide rail 32 is fixedly installed on the surface of the cache fixing plate 31 in the vertical direction, and a cache slider 33 is slidably sleeved on the surface of the cache slide rail 32, and a cache suspension rod 34 is provided at the front end of the cache slider 33 in the horizontal direction, and the cache suspension rod 34 includes two long rods parallel to each other, and a gap is left between the two long rods to ensure that the paper strip 12 to be processed passes through, and the top of the cache slider 33 is suspended on the top of the cache slide rail 32 by a buffer spring 38, and a sensor mounting plate 35 is fixedly installed on the side edge of the cache fixing plate 31, and an upper sensor 36 and a lower sensor are fixedly installed at the upper and lower ends of the sensor mounting plate 35 respectively. The upper sensor 36 and the lower sensor 37 are both connected to the paper feeding drive mechanism 2 by signal. In actual operation, if there is no need to feed paper to the subsequent process, the buffer suspension rod 34 is not supported by the tensioning force of the paper strip 12 to be processed. At this time, the buffer slide 33 will fall downward under the action of gravity. When it falls to the lower sensor 37, the sensor is triggered. At this time, the lower sensor 37 transmits a signal to the paper feeding drive mechanism 2 to stop feeding paper, thereby restoring the tensioning force of the paper strip 12 to be processed. Under the action of the tensioning force of the paper strip 12 to be processed, the buffer suspension rod 34 and the buffer slide 33 will be driven to move upward until they reach the upper sensor 36. At this time, it indicates that the paper strip 12 to be processed is over-tensioned and needs to continue feeding paper. Therefore, the upper sensor 36 continues to transmit the sensing signal back to the paper feeding drive mechanism 2 to prompt it to continue feeding paper.

[0089] See also Figure 4A guide mechanism 4 is further provided at the rear of the cache mechanism 3. The guide mechanism 4 includes a transversely mounted guide bar 41. A guide pressing piece 43 is fixedly mounted on the surface of the guide bar 41 through two mounting rings 42. The distance between the two mounting rings 42 is greater than the width of the paper strip 12 to be processed. The distance between the guide bar 41 and the guide pressing piece 43 is greater than the thickness of the paper strip 12 to be processed.

[0110] The working principle of the present invention is as follows:

[0111] During actual use of the flanging and inserting paper machine of the present invention, the paper strip 12 to be processed in the tensioning paper tray is first guided by the paper strip guide rod 21, and the paper strip 12 to be processed is fed between the paper feed drive roller 22 and the paper feed auxiliary roller 23, and the paper feed drive motor 24 drives the paper feed drive roller 22 to rotate, and cooperates with the squeezing and friction of the paper feed auxiliary roller 23 to drive the paper strip 12 to be processed to move toward the process of the cache mechanism 3, ensuring that the paper strip 12 to be processed passes through the cache hanger 34. When there is no need to feed paper to the subsequent process, the cache hanger 34 is not supported by the tensioning force of the paper strip 12 to be processed. At this time, the cache slider 33 will fall downward under the action of gravity, and when it falls to the lower sensor 37, the sensor is triggered. At this time, the lower sensor 37 transmits a signal to the paper feed drive mechanism 2 to stop feeding paper. The tensioning force of the paper strip 12 to be processed is thereby restored. Under the action of the tensioning force of the paper strip 12 to be processed, the buffer suspension rod 34 and the buffer slider 33 are driven to move upward until they reach the upper sensor 36. At this time, it is indicated that the paper strip 12 to be processed is over-tensioned and needs to continue feeding the paper. Therefore, the upper sensor 36 continues to send the sensing signal back to the paper feeding drive mechanism 2 to prompt it to continue feeding the paper. The paper strip 12 to be processed passes between the guide cross bar 41 and the guide pressure piece 43, and under the limiting action of the two mounting rings 42, the paper strip 12 to be processed is kept flat and correctly transported to the chamfering mechanism 5, and the chamfering knife 58 is used to move up and down in the knife groove 521 to chamfer the paper strip 12 to be processed passing through the chamfering paper strip channel 54. After the chamfering is completed, it enters the longitudinal indentation mechanism 6 In the longitudinal indentation paper channel 621, four indentation ridges 663 matching the longitudinal indentation grooves 623 provided on the surface of the indentation wheel body 662 roll over the surface of the paper strip 12 to be processed, and cooperate with the longitudinal indentation grooves 623 to roll out four creases on the surface of the paper strip 12 to be processed, so as to facilitate the paper folding operation in the subsequent processing steps. After the longitudinal indentation is completed, it enters the transverse indentation mechanism 7, and the paper strip 12 to be processed that enters the transverse indentation paper channel 71 passes through the upper surface of the lower indentation block 76, and is punched out a transverse indentation on the surface of the paper strip 12 to be processed through the transverse indentation grooves 751 and the transverse indentation ridges 761, so as to facilitate the subsequent flanging. After chamfering and indentation, the paper strip 12 to be processed continues to be transported to the preforming mechanism 8, and passes through the vertical forming die in turn. The tool 821, the inverting forming mold 822 and the inward folding forming mold 823 are used to fold the chamfered edge of the paper strip 12 to be processed, which was originally in a plane, downwardly into a state perpendicular to the paper surface, and then the chamfered edge of the paper strip 12 to be processed, which is folded into a state perpendicular to the paper surface by the vertical forming slope 8211, is turned inwardly to 45 degrees, and finally the chamfered edge of the paper strip 12 to be processed, which is turned inwardly to 45 degrees in the previous step, is guided into the inward folding forming slope 8232 at the pre-formed paper strip channel 85 by the inward folding guide ramp 8231, and then the chamfered edge is folded inwardly by the inward folding forming slope 8232, and finally the chamfered edge is extruded and pre-formed by the upper extrusion wheel 842 and the lower extrusion wheel 843 at the outlet of the pre-formed paper strip channel 85; for the specific flanging process of the paper strip 12 to be processed, refer to Figure 13 After the preforming is completed, the preformed paper strip 12 to be processed enters the paper feeding strip channel 971, and is clamped by the paper feeding pressing block 97 and the paper feeding base 96 and transported to the cutting and pushing paper mechanism 10 under the drive of the paper feeding motor 94. First, the downward pressing fixed cylinder 1023 drives the downward pressing fixed block 1026 to press one end of the fixed paper strip to prevent the paper strip from shifting and affecting the cutting size during cutting. Then, the cutting blade 1024 is used to cut the paper strip 12 to a preset length. Finally, the paper folding cylinder 1022 drives the paper folding pressing piece 1025 to press the cut paper strip 12 to be processed into the paper folding slot 104 for folding. After pre-forming and folding, the paper pushing mechanism 103 is started to push the folded pre-formed paper strip 12 to be processed from the paper insertion slot 105 to the indexing and rotating mechanism 11. In the process of pushing the paper, the paper feeding guide surface 1056 is first used to guide the paper strip 12 to be processed when it is pushed into the right folding mold 1052 and the left folding mold 1054. Then, the right folding inclined surface 10521 is used to fold the right side of the folded paper strip 12 inward at 90 degrees, and then the left folding inclined surface 10541 is used to fold the left side of the folded paper strip 12 inward at 90 degrees, overlapping with the right inner folding edge to form a folded paper strip 12. Figure 16 The finished shaped paper strip 13; finally, under the push of the paper push rod 1034, it enters the fixed coil hole of the stator 14 to be inserted installed on the indexing rotation mechanism 11, and the indexing rotation motor 118 drives the stator 14 to be inserted to rotate indexingly, so as to facilitate the precise and continuous pushing out of the finished shaped paper strip 13 and inserting it into the stator 14 to be inserted. Moreover, since the finished shaped paper strip 13 with a flanging structure formed by automatic folding of the present invention is inserted into the coil hole of the stator 14 to be inserted, the stroke length of the insertion of the insulating paper can be controlled by the fixed length of the flanging structure, thereby realizing the precise insertion of the insulating paper, avoiding deformation of the insulating paper or failure to insert it to the accurate position, affecting the quality of paper insertion, and causing insulation failure between the coil and the stator.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
