Description

Technical Field

[0001] The present invention belongs to the technical field of insulating paper tape pasting and hemming devices, and specifically relates to an insulating paper tape pasting and hemming device. Background Art

[0002] During the production process of motors, insulating paper is widely used on the stator core due to its excellent insulating ability and mechanical properties to improve the insulation performance between the winding and the bottom of the stator core slot. Traditional generator manufacturers usually directly insert the insulating paper into the bottom of the slot to separate the winding from the stator core and improve the insulation performance between the winding and the stator core;

[0003] When pasting the insulating paper tape on the bottom of some slots, affected by the special shape of the bottom of the slot and the width of the insulating paper tape, the width of the insulating paper tape is usually greater than the width of the bottom wall of the slot. This causes the two sides of the insulating paper tape not to fit with the bottom wall and the side wall of the slot when the insulating paper tape is pasted in the slot, resulting in a suspension between the two sides of the insulating paper tape and the bottom wall and the side wall of the slot, thus affecting the pasting effect of the insulating paper tape; at the same time, when there is a suspension between the two sides of the insulating paper tape and the bottom wall and the side wall of the slot, it will also cause the insulating paper tape to displace towards one side wall in the slot when a pulling force is applied to the insulating paper tape during the pasting process of the insulating paper tape, which leads to the failure of the pasting function of the insulating paper tape in the slot;

[0004] Secondly, when some existing hemming devices hem the insulating paper tape, the hemmed edge of the insulating paper tape will also reset, resulting in poor hemming effect. For this reason, an insulating paper tape pasting and hemming device is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an insulating paper tape pasting and hemming device that can overcome the above problems or at least partially solve the above problems.

[0006] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is: an insulating paper tape pasting and hemming device, including a base, and further including: a plurality of pressing rollers and a plurality of roller members provided on the base; hemming plates respectively provided above both ends of the pressing rollers and the roller members; a pressing assembly provided at both ends of the hemming plates. When the insulating tape passes above the pressing rollers and the roller members, the reciprocatingly moving hemming plates press down the two sides of the insulating tape for hemming, and at the same time, vertical reinforcing rib grooves are pressed on the folded surface of the insulating tape during the downward hemming.

[0007] Preferably, the profiling roller includes a first support roller rotatably connected to the base and round blocks located at both ends of the first support roller. The round blocks are fixedly connected to the base, and profiling grooves are formed on the surfaces of the round blocks.

[0008] Preferably, the roller member includes a second support roller and outer rollers connected to both ends of the second support roller. An installation block is installed on the base, and the second support roller and the outer rollers are rotatably connected to the installation block through a connecting shaft.

[0009] Preferably, an installation plate is installed on the base, a support plate is connected to the installation plate, a cylinder is installed on the support plate, a connecting plate is installed on the telescopic end of the cylinder, guide rods are symmetrically connected to the connecting plate, and the guide rods penetrate through the installation plate and are connected to the flanging plate.

[0010] Preferably, the profiling assembly includes a first profiling rod. Sliding rods are fixedly connected to both ends of the flanging plate. A connecting block is slidably connected to the sliding rods. The connecting block is connected to one end of the sliding rod through a second spring. The first profiling rod is connected to the connecting block, and the first profiling rod corresponds to the profiling groove.

[0011] Further, a second profiling rod is fixedly connected to the inner side of the middle of the flanging plate, and the second profiling rod is horizontal with the bottom wall of the base.

[0012] Further, the two flanging plates are connected by a cross plate.

[0013] Further, connecting rods are fixedly connected to the installation blocks on the roller members on both sides of the second profiling rod. Friction wheels are rotatably connected to the connecting rods, and a shaping friction area is formed between the two friction wheels.

[0014] Preferably, a first spring is connected between the connecting plate and the installation plate.

[0015] A method for pasting and folding the edges of an insulating paper tape includes the following steps:

[0016] S1. The insulating tape passes through the base, and the cylinder reciprocates up and down to fold the two side edges of the insulating tape downward through the flanging plate.

[0017] S2. When the flanging plate presses down, the second profiling rod contacts both sides of the middle of the insulating tape to form a transverse reinforcing rib groove.

[0018] S3. When the flanging plate presses down, the first profiling rod presses the vertical reinforcing rib groove at the folded edge of the insulating tape, thereby completing the folding of the insulating tape.

[0019] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: In the process of hemming, the present invention presses the hemming position to form a vertical reinforcing rib groove, effectively avoiding a large degree of reset at the hemming position, enabling the hemmed insulating tape to better contact the bottom of the groove, avoiding suspension and displacement, and further pressing a horizontal reinforcing rib groove on the upper part of the insulating tape through the second profiling rod, which further resets the hemmed insulating tape;

[0020] And when the horizontal reinforcing rib groove is located at the first profiling rod, the hemming plate moves downward and presses the insulating tape at the hemming position to form a vertical reinforcing rib groove. At this time, the vertical reinforcing rib groove will be connected to the horizontal reinforcing rib groove, forming an L-shaped reinforcing rib groove on the insulating tape, which can further prevent the reset of the hemmed insulating tape and make the quality of the hemmed insulating tape better;

[0021] The roller parts on both sides of the second profiling rod rotate in opposite directions through a motor, and the friction wheel contacts the outer roller on the roller part. Therefore, when the roller part rotates, the friction wheel will also rotate, and the two friction wheels rotate relatively, and a plastic deformation friction area will be formed between the two friction wheels;

[0022] When the second profiling rod presses down on the insulating tape, when the bottom surface of the horizontal reinforcing rib groove contacts the two friction wheels, the relatively rotating friction wheels will further shape the horizontal reinforcing rib groove to prevent the shape of the horizontal reinforcing rib groove from resetting.

Specific embodiments

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0036] Embodiment 1: Refer to Figures 1 - 10 , a device for pasting and folding the edge of an insulating paper tape, including a base 1, and further including: a plurality of profiled rollers 12 and a plurality of roller members 13 provided on the base 1; a folding plate 15 respectively provided above both ends of the profiled rollers 12 and the roller members 13; a profiling assembly provided at both ends of the folding plate 15. When the insulating tape 11 passes above the profiled rollers 12 and the roller members 13, the reciprocating up-and-down moving folding plate 15 presses down on both sides of the insulating tape 11 for edge folding, and while pressing down for edge folding, vertical reinforcing rib grooves 101 are pressed on the folded surface of the insulating tape 11.

[0037] The profiled roller 12 includes a first support roller 120 rotatably connected to the base 1 and round blocks 121 located at both ends of the first support roller 120. The round blocks 121 are fixedly connected to the base 1, and profiled grooves 122 are formed on the surfaces of the round blocks 121. The frictional force between the first support roller 120 and the insulating tape 11 can cause the first support roller 120 to rotate, thereby reducing the friction on the insulating tape 11;

[0038] The roller member 13 includes a second support roller 130 and outer rollers 131 connected to both ends of the second support roller 130. An installation block 1300 is installed on the base 1, and the second support roller 130 and the outer rollers 131 are rotatably connected to the installation block 1300 through a connecting shaft 132, and both the second support roller 130 and the outer rollers 131 can rotate;

[0039] An installation plate 14 is installed on the base 1. A support plate 141 is connected to the installation plate 14. A cylinder 142 is installed on the support plate 141. A connecting plate 143 is installed on the telescopic end of the cylinder 142. Guide rods 144 are symmetrically connected to the connecting plate 143. The guide rods 144 penetrate through the installation plate 14 and are connected to the folding plate 15; A first spring 145 is connected between the connecting plate 143 and the installation plate 14;

[0040] The profiled component includes a first profiled rod 156. Slide rods 153 are fixedly connected to both ends of the folding plate 15. A connecting block 152 is slidably connected to the slide rods 153. The connecting block 152 is connected to one end of the slide rod 153 through a second spring 154. The first profiled rod 156 is connected to the connecting block 152. The first profiled rod 156 corresponds to the profiled groove 122. A limiting rod 155 is fixedly connected to the connecting block 152. The limiting rod 155 slides in the hollow groove of the folding plate 15. The setting of the second spring 154 can make the first profiled rod 156 fit tightly with the profiled groove 122, thereby improving the profiling effect on the insulating tape 11;

[0041] When the device is in use, the insulating tape 11 passes above the profiled roller 12 and the roller member 13;

[0042] In this embodiment, the numbers of the profiled roller 12 and the roller member 13 are two and four respectively, and the distribution positions are as Figure 4 shown;

[0043] When the insulating tape 11 passes through, the cylinder 142 reciprocally pushes the folding plate 15 to move up and down. The initial position of the bottom surface of the folding plate 15 is above the insulating tape 11. Therefore, when the folding plate 15 moves downward, the two sides of the insulating tape 11 will be folded downward, and the folded insulating tape 11 is in contact with the round blocks 121 and the outer rollers 131, thereby realizing rapid and effective folding of the insulating tape 11;

[0044] During the hemming process, when the first pressing rods 156 at both ends of the hemming plate 15 move downward from top to bottom, they will press the insulating tape 11 into the pressing groove 122, so that a downward vertical reinforcing rib groove 101 is formed at the hem of the insulating tape 11, so as to achieve better support for the hemmed insulating tape 11, and thus effectively avoid a large degree of reset of the hemmed insulating tape 11. Therefore, in this device, during the hemming process, the hem is further pressed to form a vertical reinforcing rib groove 101, effectively avoiding a large degree of reset at the hem, so that the hemmed insulating tape 11 can better contact the bottom of the groove, avoiding suspension and displacement.

[0045] It should be understood that the movement of the insulating tape 11 on the base 1 is intermittent. When the air cylinder 142 is reset, the first pressing rod 156 disengages from the pressing groove 122, and the insulating tape 11 moves again.

[0046] Example 2: Refer to Figure 9 , an insulating paper tape pasting and hemming device, which is basically the same as Example 1. Further: The two hemming plates 15 are connected by a cross plate 151;

[0047] When the hemming plate 15 presses down, the cross plate 151 will press the insulating tape 11 on the pressing roller 12 and the roller member 13, so that when the hemming plate 15 is hemming, the middle of the insulating tape 11 is prevented from bulging.

[0048] Example 3: Refer to Figures 1 - 10, an insulating paper tape pasting and hemming device, including a base 1, and further including: a plurality of profiling rollers 12 and a plurality of roller members 13 provided on the base 1; hemming plates 15 respectively provided above both ends of the profiling rollers 12 and the roller members 13; a profiling assembly provided at both ends of the hemming plates 15. When the insulating tape 11 passes above the profiling rollers 12 and the roller members 13, the reciprocatingly moving hemming plates 15 press down on both sides of the insulating tape 11 for hemming, and at the same time of pressing down for hemming, vertical reinforcing rib grooves 101 are pressed on the folded surface of the insulating tape 11; the profiling roller 12 includes a first support roller 120 rotatably connected to the base 1 and round blocks 121 located at both ends of the first support roller 120. The round blocks 121 are fixedly connected to the base 1, and profiling grooves 122 are provided on the surfaces of the round blocks 121. The frictional force between the first support roller 120 and the insulating tape 11 can cause the first support roller 120 to rotate, thereby reducing the friction on the insulating tape 11; the roller member 13 includes a second support roller 130 and outer rollers 131 connected to both ends of the second support roller 130. An installation block 1300 is installed on the base 1, and the second support roller 130 and the outer rollers 131 are rotatably connected to the installation block 1300 through a connecting shaft 132, and both the second support roller 130 and the outer rollers 131 can rotate; an installation plate 14 is installed on the base 1, a support plate 141 is connected to the installation plate 14, a cylinder 142 is installed on the support plate 141, a connecting plate 143 is installed on the telescopic end of the cylinder 142, guide rods 144 are symmetrically connected to the connecting plate 143, and the guide rods 144 penetrate through the installation plate 14 and are connected to the hemming plates 15; a first spring 145 is connected between the connecting plate 143 and the installation plate 14; the profiling assembly includes a first profiling rod 156. Slide rods 153 are fixedly connected to both ends of the hemming plates 15. A connecting block 152 is slidably connected to the slide rods 153. The connecting block 152 is connected to one end of the slide rod 153 through a second spring 154. The first profiling rod 156 is connected to the connecting block 152, and the first profiling rod 156 corresponds to the profiling groove 122. Further, a second profiling rod 16 is fixedly connected to the inner side of the middle part of the hemming plate 15, and the second profiling rod 16 is horizontal with the bottom wall of the base 1.

[0049] By setting the second profiling rod 16 in this device, when the cylinder 142 pushes the hemming plate 15 to move downward, the second profiling rod 16 presses a transverse reinforcing rib groove 102 on the upper part of the insulating tape 11, which enables the folded insulating tape 11 to be further reset.

[0050] In one embodiment, when the transverse reinforcing rib groove 102 is located at the first pressing rod 156, the hemming plate 15 moves downward and presses the insulating tape 11 at the hem to form the vertical reinforcing rib groove 101. At this time, the vertical reinforcing rib groove 101 will be connected to the transverse reinforcing rib groove 102, forming an L-shaped reinforcing rib groove on the insulating tape 11, which can further prevent the insulating tape 11 after hemming from resetting and make the quality of the insulating tape 11 after hemming better.

[0051] Embodiment 4: Refer to Figure 8 , an insulating paper tape pasting and hemming device, which is basically the same as Embodiment 3. Further, connecting rods 135 are fixedly connected to the mounting blocks 1300 on the roller members 13 on both sides of the second pressing rod 16, and friction wheels 133 are rotatably connected to the connecting rods 135;

[0052] When the second pressing rod 16 presses the insulating tape 11, the bottom surface of the transverse reinforcing rib groove 102 contacts the friction wheel 133, so that the transverse reinforcing rib groove 102 can be shaped, making the connection between the transverse reinforcing rib groove 102 and the vertical reinforcing rib groove 101 smoother and further preventing the insulating tape 11 after hemming from resetting.

[0053] In one embodiment, the roller members 13 on both sides of the second pressing rod 16 rotate in opposite directions through a motor, and the friction wheel 133 contacts the outer roller 131 on the roller member 13. Therefore, when the roller member 13 rotates, the friction wheel 133 also rotates, and the two friction wheels 133 rotate relatively, and a plastic shaping friction area 134 is formed between the two friction wheels 133;

[0054] When the second pressing rod 16 presses down the insulating tape 11, when the bottom surface of the transverse reinforcing rib groove 102 contacts the two friction wheels 133, the relatively rotating friction wheels 133 will further shape the transverse reinforcing rib groove 102 to prevent the shape of the transverse reinforcing rib groove 102 from resetting.

[0055] Embodiment 5: Refer to Figures 1 - 10 , an insulating paper tape pasting and hemming method, which includes the following steps:

[0056] S1. The insulating tape 11 passes through the base 1, and the cylinder 142 reciprocates up and down to fold the two sides of the insulating tape 11 downward through the hemming plate 15;

[0057] S2. When the hemming plate 15 presses down, the second pressing rod 16 contacts both sides of the middle of the insulating tape 11 to form the transverse reinforcing rib groove 102;

[0058] S3. When the hemming plate 15 presses down, the first pressing rod 156 presses the vertical reinforcing rib groove 101 at the hem of the insulating tape 11, thereby completing the hemming of the insulating tape 11.

[0059] In the process of hemming, the present invention presses the hemming position to form a vertical reinforcing rib groove 101, effectively avoiding a large degree of reset at the hemming position, enabling the hemmed insulating tape 11 to better contact the bottom of the groove, preventing suspension and displacement, and further pressing a transverse reinforcing rib groove 102 above the insulating tape 11 through the second profiling rod 16, which further resets the hemmed insulating tape 11;

[0060] And when the transverse reinforcing rib groove 102 is located at the first profiling rod 156, the hemming plate 15 moves downward and presses the vertical reinforcing rib groove 101 on the insulating tape 11 at the hemming position. At this time, the vertical reinforcing rib groove 101 will be connected to the transverse reinforcing rib groove 102, forming an L-shaped reinforcing rib groove on the insulating tape 11, which can further prevent the hemmed insulating tape 11 from resetting and improve the quality of the hemmed insulating tape 11.

[0061] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention.
