[0023] The specific embodiments of the present invention will be further described in detail below based on the accompanying drawings. It should be understood that the description of the embodiments of the present invention herein does not limit the protection scope of the present invention.

[0024] Please refer to Figure 1, which is a schematic structural diagram of a fully automatic hot melt system for insulating paper edge turning of the present invention. The fully automatic hot melt system for insulating paper edge turning is used for bending and turning the edge of insulating paper. The fully automatic hot melt system for insulating paper edge turning includes a frame 11, a feeding mechanism 12 installed on the frame 11, a pushing mechanism 13 installed on the frame 11, a cutting mechanism 14 installed on the frame 11, a bending mechanism 15 installed on the frame 11, an intermediate plate 16 installed on the frame 11 and located between the feeding mechanism 12 and the bending mechanism 15, and a collecting mechanism 17 installed on the frame 11. The fully automatic hot melt system for insulating paper edge turning also includes some other functional modules, such as installation components, connection components, gas sources, etc., which should be well known to those skilled in the art, so they will not be described in detail here.

[0025] First, the structural functions of the frame 11 will be described. The frame 11 should be made of steel to have a certain structural strength. There is an installation tabletop 110 on the frame 11, and the installation tabletop 110 is used to install the feeding mechanism 12, the pushing mechanism 13, the cutting mechanism 14, the bending mechanism 15, the intermediate plate 16, the collecting mechanism 17 and some other functional modules.

[0026] Please refer to Figure 1 and Figure 2, the feeding mechanism 12 includes a motor 121 fixed on the frame 11, a first guide roller 122 connected to the output shaft of the motor 121, a second guide roller 123 cooperating with the first guide roller 122 to convey the insulating paper, and a material passing unit 18 located between the feeding mechanism 12 and the intermediate plate 16. The motor 121 is an electromagnetic device that realizes the conversion or transfer of electrical energy based on the law of electromagnetic induction. It is a prior art and is used to drive the first guide roller 122 to rotate. The feeding mechanism 12 further includes a mounting frame 124. A first gear 126 is provided at one end of the first guide roller 122 away from the motor 121. Mounting seats 127 are respectively provided at both ends of the second guide roller 123 by bearing connections. A second gear 128 is also connected to the second guide roller 123. The second gear 128 meshes with the first gear 126. An adjusting mechanism 129 is provided on the mounting frame 124. The adjusting mechanism 129 is connected to the mounting frame 124 to adjust the distance between the first guide roller 122 and the second guide roller 123. The adjusting mechanism 129 is specifically a screw rod. One end of the screw rod is fixedly connected to the mounting seat 127. The screw rod is threadedly connected to the mounting frame 124. The end of the screw rod away from the mounting seat 127 rotates to make the screw rod rise or fall, so that the distance between the second guide roller 123 and the first guide roller 122 can be adjusted. It should be noted that the first gear 126 and the second gear 128 at both ends of the first guide roller 122 and the second guide roller 123 are always meshed. Thus, when the motor 121 drives the first guide roller 122 to rotate, the second guide roller 123 also rotates in cooperation to convey the insulating paper.

[0027] Please refer to Figure 3 and Figure 4 , the material passing unit 18 includes two upper pressing plates 181, and a bottom plate 182 located below the upper pressing plates 181 and having one end abutted against the intermediate plate 16. Each side of each upper pressing plate 181 facing the bottom plate 182 is provided with a material passing groove 183. The two material passing grooves 183 cooperate to penetrate the insulating paper.

[0028] Please refer to Figures 3 to 5, a first notch 161 for conveying insulating paper and located above the bottom plate 182 and a second notch 162 located below the first notch 161 are formed on the intermediate plate 16. The frame 11 is further provided with a second driving device 163 located below the intermediate plate 16. An output shaft of the second driving device 163 is connected with a first mounting plate 164. Guide posts 165 are respectively arranged at two ends of the first mounting plate 164. The guide posts 165 vertically penetrate through the intermediate plate 16 and are connected with a second mounting plate 166. The cutting mechanism 14 is fixed on the second mounting plate 166.

[0029] Please refer to Figures 4 to 7 , the pushing mechanism 13 includes a cylinder 131 fixed on the frame 11 and a push rod 132 driven by the cylinder 131 and passing through the second notch 162. An avoidance groove 184 is formed at the bottom of the bottom plate 182 close to the intermediate plate 16. The push rod 132 is movably located in the avoidance groove 184. The cylinder 131 is located on one side of the material passing unit 18. The push rod 132 is of an L-shaped structure, which makes the installation of each functional module more reasonable and fully utilizes the space of the frame 11.

[0030] The cutting mechanism 14 includes a cutting tool holder 141 arranged on the intermediate plate 16 close to the bending mechanism 15. Specifically, the cutting tool holder 141 is installed on the second mounting plate 166, a cutting base 142 fixed on the intermediate plate 16 and located below the cutting tool holder 141. A cutting tool 143 for cutting the insulating paper is installed on the cutting tool holder 141. The cutting base 142 includes a first end block 146 fixedly connected with the intermediate plate 16 and a second end block 147 located above the first end block 146. A first through groove 148 is formed on the top surface of the first end block 146. A second through groove 149 communicated with the first through groove 148 is formed on the bottom surface of the second end block 147. The first through groove 148 and the second through groove 149 are perpendicularly arranged, wherein the second through groove 149 is horizontally arranged. The push rod 132 passes through the first through groove 148 and partially passes through the second through groove 149. When the insulating paper is conveyed into the second through groove 149, the cutting mechanism 14 cuts the insulating paper. The cut insulating paper is pushed to the bending mechanism 15 by the push rod 132. The push rod 132 partially passes through the second through groove 149 so that the push rod 132 contacts the insulating paper to realize the pushing of the insulating paper.

[0031] Please refer to Figure 1, the bending mechanism 15 includes two forming blocks 151 arranged on the frame 11, and a stamping unit 152 located above the two forming blocks 151. The stamping unit 152 includes a first driving device 153 fixed on the frame 11, a mounting block 154 connected to the output end of the first driving device 153, and a stamping block 155 fixed on the mounting block 154. The bottom surface of the stamping block 155 is recessed inward to form a concave arc surface (not shown in the figure), and two pointed parts (not shown in the figure) are formed at both ends of the bottom corresponding to the concave arc surface. The pointed parts abut against the edge of the insulating paper for stamping, so as to improve the bending accuracy of the insulating paper and adapt to some bendings at the edge. A fixing end block 156 for fixing the forming block 151 is provided on one side of each forming block 151. The fixing end block 156 is used to fix the forming block 151, so that the forming block 151 still maintains its original position after multiple stampings, further improving the bending accuracy. A heater (not shown in the figure) is provided in the stamping block 155. The heater includes a resistance wire, a resistance coil, a quartz tube or other heating elements. The heater heats the stamping block 155, and the stamping block 155 transfers the heat to the insulating paper. The heater should be connected to a power supply and other energy supply components, which are well-known to those skilled in the art, so it will not be elaborated here. In this embodiment, the stamping block 155 is heated to 165 °C by the heater to stamp the insulating paper, and the insulating paper is stamped and formed on the forming block 151, which helps the rapid forming of the insulating paper and prevents the insulating paper from rebounding after bending.

[0032] Please refer to Figure 1 and Figure 6 , the material receiving mechanism 17 includes a blowing unit 171 arranged on one side of the two forming blocks 151 close to the cutting mechanism 14, and a material receiving box 172 located on one side of the two forming blocks 151 far from the cutting mechanism 14. The blowing unit 171 includes a nozzle and a gas source (not shown in the figure) connected to the nozzle. Supplying gas to the nozzle by the gas source is a prior art and will not be described in detail here. The nozzle blows the cut insulating paper towards the material receiving box 172, so that the insulating paper falls into the material receiving box 172. The cross-section of the material receiving box 172 is trapezoidal, and the height of the end of the material receiving box 172 close to the bending mechanism 15 is higher than the height of the end of the material receiving box 172 far from the bending mechanism 15, which is more convenient for blanking and collection.

[0033] In this embodiment, the insulating paper is conveyed by the cooperative rotation of the first guide roller 122 and the second guide roller 123. The insulating paper passes through the material passing groove 183, the first notch 161 of the intermediate plate 16, and the second through groove 149 and is sent to the two forming blocks 151, so that each conveyance is on a preset route, ensuring the subsequent bending accuracy. The cutting mechanism 14 cuts the insulating paper, and the cut insulating paper is pushed by the push rod 132 driven by the cylinder 131 to a preset position of the two forming blocks 151. The stamping block 155 is heated to 165°C by the heater to stamp the insulating paper, and the formed insulating paper is blown by the blowing unit 171 of the material collecting mechanism 17 into the material collecting box 172.

[0034] Compared with the prior art, the fully automatic hot melt system for insulating paper flanging provided by the present invention feeds the insulating paper through the feeding mechanism. The insulating paper passes through the material passing groove 183, the first notch 161, and the second through groove 149 in sequence and is sent to the forming block 151. The conveying process is smooth and stable. Then, the cutting mechanism 14 cuts the insulating paper, and the cut insulating paper is pushed by the push rod 132 driven by the cylinder 131 to a preset position of the forming block 151. The stamping block 155 stamps the insulating paper, and the formed insulating paper is recycled by the material collecting mechanism 17. The process is simple, greatly reducing the labor, improving the production efficiency, and enabling the position of the product to be always controlled by conveying the product through each notch in sequence, thereby improving the bending accuracy.
