Detailed Embodiment

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Refer to Figures 1 - 5 , the present invention provides two technical solutions:

[0026] The first implementation method: An automatic feeding device for heating pad production, including a workbench 1, and a feeding assembly 2 is provided on the top surface of the workbench 1 for feeding the heating pad. The feeding assembly 2 includes:

[0027] A fixing component 21, which is arranged on the top surface of the workbench 1 to fix the position of the heating pad material roll;

[0028] Adjusting assembly 22 is arranged on the top surface of the workbench 1 and is used to adjust the tension when the heating pad is loaded. The adjusting assembly 22 includes a mounting frame 221 fixedly installed on the top surface of the workbench 1. Two first rollers 223 are movably installed inside the mounting frame 221. Limiting grooves 227 are opened on both the front and rear sides inside the mounting frame 221. A limiting block 2211 is movably installed inside the limiting groove 227. A second roller 229 is movably installed on the opposite sides of the limiting block 2211. A limiting rod 2210 is fixedly installed inside the limiting groove 227. A spring 226 is movably sleeved on the outer side of the limiting rod 2210, and the limiting rod 2210 can limit the position of the spring 226. A limiting assembly is arranged on the bottom surface of the mounting frame 221 to prevent the heating pad from shifting during loading. The adjusting assembly 22 further includes a top plate 228 fixedly installed on the opposite sides of the limiting block 2211. A handle 224 is fixedly installed on the top surface of the top plate 228. The top surface of the handle 224 movably penetrates through the inside of the mounting frame 221 and extends to the top surface of the mounting frame 221. The limiting assembly includes sliding grooves 2212 opened on both the left and right sides of the inner top surface of the mounting frame 221. Sliders 2213 are slidably installed at both the front and rear ends of the sliding grooves 2212. A left-right threaded screw 225 is movably installed inside the sliding grooves 2212. A limiting roller 222 is movably installed on the bottom surface of the slider 2213. The bottom end of the limiting rod 2210 movably penetrates through the top surface of the limiting block 2211 and is fixedly installed on the bottom surface of the limiting groove 227. The bottom end of the spring 226 is fixedly installed on the top surface of the limiting block 2211. The top end of the spring 226 abuts against the top surface of the limiting groove 227. The elastic force of the spring 226 can drive the limiting block 2211 to press down the second roller 229. At this time, the heating pad can be pressed by the two first rollers 223 to make it straight. The rear end of the left-right threaded screw 225 threadedly penetrates through the front side of the slider 2213 and is movably installed at the rear end of the sliding groove 2212. The front end of the left-right threaded screw 225 movably penetrates through the inside of the sliding groove 2212 and extends to the front side of the mounting frame 221. Rotating the left-right threaded screw 225 can drive the slider 2213 to move towards the opposite sides. Then the slider 2213 will drive the limiting roller 222 to move to limit the heating pad.

[0029] The provided limiting roller 222 can limit the trajectory of the heating pad during loading. During use, the heating pad is passed through between the first roller 223 and the second roller 229. Then rotate the left-right threaded screw 225 to drive the slider 2213 to move towards the opposite sides. At this time, the slider 2213 will drive the limiting roller 222 to move and stick to both sides of the heating pad to limit it, avoiding the heating pad from shifting and wrinkling during loading, and improving the production efficiency and product quality of the device.

[0030] The second implementation mode is mainly different from the first implementation mode in that: the fixing component 21 includes a side plate 211 fixedly installed on the top surface of the workbench 1. An activity shaft 212 is movably installed on the front side of the side plate 211. A plurality of slots 213 are formed on the top surface of the activity shaft 212. An activity cylinder 216 is movably installed on the outer side of the activity shaft 212. A fixed disk 214 is fixedly installed on the rear side of the activity cylinder 216. An adjusting screw 215 is threadedly installed on the top surface of the activity cylinder 216. The bottom end of the adjusting screw 215 threadedly penetrates through the top surface of the activity cylinder 216 and extends into the plurality of slots 213. Rotating the adjusting screw 215 can insert it into the plurality of slots 213 to fix the activity cylinder 216.

[0031] The fixing disk 214 and the adjusting screw 215 provided can fix heating pad rolls with different widths. During use, the heating pad roll is sleeved on the outer side of the activity shaft 212. Then, the activity cylinder 216 is sleeved on the outer side of the activity shaft 212 so that the fixed disk 214 is attached to one end of the heating pad roll. Then, the adjusting screw 215 is rotated to insert it into the slot 213 to fix the activity cylinder 216. At this time, the position of the heating pad roll can be fixed through the fixed disk 214, which is convenient for fixing and has good practicability.

[0032] Meanwhile, the content not described in detail in this specification belongs to the well-known prior art in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0033] During use, the user sleeved the heating pad roll on the outer side of the activity shaft 212. Then, the activity cylinder 216 is sleeved on the outer side of the activity shaft 212 so that the fixed disk 214 is attached to one end of the heating pad roll. Then, the adjusting screw 215 is rotated to insert it into the slot 213 to fix the activity cylinder 216. At this time, the position of the heating pad roll can be fixed through the fixed disk 214. Then, one end of the heating pad is passed through the space between the first roller 223 and the second roller 229 for subsequent processes. Then, the positive and negative thread screw 225 is rotated to drive the slider 2213 to move towards the opposite side. At this time, the slider 2213 will drive the limiting roller 222 to move and stick to both sides of the heating pad to limit it. Then, unwinding and loading are carried out. At this time, the elastic force of the spring 226 can drive the limiting block 2211 to press down the second roller 229. Then, the heating pad can be pressed by the two first rollers 223 to make it straight and avoid wrinkles.
