[0001] This utility model relates to the field of packaging equipment technology, and in particular to a rolling and packaging device for overnight pants. Background Technology

[0002] With the increasing demand for comfortable and high-quality sleepwear products in the consumer market, over-the-counter pants, as one of the main products in comfortable sleepwear, have received widespread attention in the market. To meet the demands of efficient production and high-quality packaging, various automated equipment has emerged in the production process of over-the-counter pants. Especially in the packaging stage, how to improve efficiency, reduce waste, and enhance the aesthetics and stability of product packaging has become a challenge that manufacturers need to solve.

[0003] Most existing overnight pants packing devices use a bagging method to pack the overnight pants. However, when carrying overnight pants out, this method is prone to causing the elastic fabric to bulge and take up a lot of space, making it inconvenient to carry. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rolling and packaging device for sleeping pants.

[0005] This utility model is achieved by the following technical solution: a rolling and packing device for sleeping pants, including a rolling and packing device housing, a rolling component is provided inside the rolling and packing device housing, and a limiting component is provided at the bottom of the rolling component.

[0006] The rolling assembly includes a drive motor, which is fixedly connected to the inner wall of the rolling and packaging device housing. A motor rotating rod is fixedly connected to the output end of the drive motor. A drive disk is fixedly connected to the end of the motor rotating rod away from the drive motor. A T-shaped limiting groove is formed on the front of the drive disk. A T-shaped limiting slider is slidably connected to the inner wall of the T-shaped limiting groove. A winding half-shaft is fixedly connected to the front of the T-shaped limiting slider. A winding rod is fixedly connected to the front of the winding half-shaft. A micro motor is fixedly connected to the inner wall of the rolling and packaging device housing. A bidirectional threaded rod is fixedly connected to the output end of the micro motor. A limiting gear is fixedly connected to the outer wall of the bidirectional threaded rod. A synchronous rack is meshed with the outer wall of the limiting gear. The synchronous rack is located away from the... One end of the limiting gear is meshed with a second limiting gear. A second bidirectional threaded rod is fixedly connected to the inner wall of the second limiting gear. A threaded slider is threadedly connected to the outer wall of the second bidirectional threaded rod. A limiting block is fixedly connected to the surface of the threaded slider. A limiting rod is fixedly connected to the surface of the limiting block. An avoidance limiting groove is opened on the front of the winding half shaft. A second threaded slider is threadedly connected to the outer wall of the second bidirectional threaded rod. A second limiting block is fixedly connected to the surface of the second threaded slider. A second limiting rod is fixedly connected to the surface of the second limiting block. A second winding half shaft is slidably connected to the surface of the second limiting block. An avoidance limiting groove is opened on the surface of the second winding half shaft. A second winding rod is fixedly connected to the surface of the second winding half shaft. A T-shaped limiting slider is fixedly connected to the back of the second winding rod.

[0007] As a further improvement to the above solution, two T-shaped limiting slides are provided, and the two T-shaped limiting slides are evenly arranged around the center of the drive disk. Two threaded sliders are provided, and the two threaded sliders are symmetrically arranged around the motor rotating rod. Two threaded sliders are provided, and two limiting rods are provided.

[0008] As a further improvement to the above solution, the outer wall of the bidirectional threaded rod is rotatably connected to the inner wall of the housing of the rolling and packing device, the outer wall of the second bidirectional threaded rod is rotatably connected to the inner wall of the housing of the rolling and packing device, the outer wall of the limiting rod is slidably connected to the inner wall of the avoidance limiting groove, the outer wall of the second limiting rod is slidably connected to the inner wall of the second avoidance limiting groove, and the outer wall of the second T-shaped limiting slider is slidably connected to the inner wall of the evenly arranged T-shaped limiting slide groove.

[0009] With the above technical solution, when the rolling assembly inside the outer shell of the rolling and packing device is working, the drive motor starts, and its output end drives the motor rotating rod to rotate, which in turn drives the drive disc to rotate. When the drive disc rotates, the T-shaped limiting slide groove on its front side drives the T-shaped limiting slider to rotate, which in turn drives the winding half shaft and winding rod to rotate. At the same time, the drive disc drives the second T-shaped limiting slider through its T-shaped limiting slide groove, which in turn drives the second winding half shaft and winding rod to rotate, thereby realizing the rolling action of the sleeping pants.

[0010] As a further improvement to the above solution, the limiting component includes a T-shaped slide groove, which is formed on the front of the housing of the rolling and packing device. A T-shaped slider is slidably connected to the inner wall of the T-shaped slide groove, and a limiting plate is fixedly connected to the front of the T-shaped slider.

[0011] As a further improvement to the above solution, a spring limiting rod is slidably connected to the inner wall of the T-shaped slider. The spring limiting rod is fixedly connected to the inner wall of the outer shell of the rolling and packing device. The top of the spring limiting rod penetrates the inner wall of the T-shaped slider, and a limiting spring is fixedly connected to the bottom of the T-shaped slider.

[0012] As a further improvement to the above solution, a worm gear is rotatably connected to the inner wall of the outer shell of the rolling and packing device. An adjustment groove is provided on the right side of the worm gear. A worm wheel is threadedly connected to the outer wall of the worm gear, and a threaded rod is fixedly connected to the inner wall of the worm wheel.

[0013] As a further improvement to the above solution, the outer wall of the threaded rod is rotatably connected to the inner wall of the housing of the rolling and packing device, and a T-shaped lifting slider is threadedly connected to the outer wall of the threaded rod. The threaded rod passes through the inner wall of the T-shaped lifting slider and extends therethrough. The outer wall of the T-shaped lifting slider is slidably connected to the inner wall of the T-shaped slide groove, and the top of the T-shaped lifting slider is fixedly connected to the bottom of the spring limiting rod.

[0014] Through the above technical solution, the worm gear is adjusted to rotate, thereby causing the worm gear to mesh with the rotating worm wheel, which in turn causes the worm wheel to rotate the threaded rod. This causes the T-shaped lifting slider to slide upward along the outer wall of the threaded rod and the inner wall of the T-shaped groove, while the inner wall of the T-shaped lifting slider slides along the outer wall of the spring limit rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] When the rolling assembly inside the outer shell of this utility model's rolling and packaging device is working, the drive motor starts, and its output end drives the motor rotating rod to rotate, which in turn drives the drive disc to rotate. As the drive disc rotates, the T-shaped limiting groove on its front side drives the T-shaped limiting slider to rotate, which in turn drives the winding half-shaft and winding rod to rotate. Simultaneously, the drive disc, through its T-shaped limiting groove, drives a second T-shaped limiting slider, which in turn drives a second winding half-shaft and a second winding rod to rotate, thus achieving the desired rotation. During the rolling-up motion of the pants, as the two winding half-shafts rotate, the winding half-shaft, through its surface-cut clearance limiting groove, connects to the limiting block via a sliding limiting rod on its inner wall. Simultaneously, the second winding half-shaft, through its surface-cut clearance limiting groove, connects to the limiting block via a sliding limiting rod on its inner wall. This ensures that during the rotation of the two winding half-shafts, the limiting rods and the second limiting rod will move along the clearance limiting groove. The positioning slot and the second avoidance limiting slot rotate to avoid each other. At the same time, the micro motor starts, and its output end drives the bidirectional threaded rod to rotate. The bidirectional threaded rod drives the limiting gear to rotate. The limiting gear drives the second limiting gear to rotate through the synchronous rack. The second limiting gear drives the second bidirectional threaded rod to rotate. This causes the bidirectional threaded rod and the second bidirectional threaded rod to move the threaded slider and the second threaded slider inward and outward at the same time. At the same time, the threaded slider and the second threaded slider drive the second limiting block and the second limiting block to slide inward and outward at the same time. This causes the second limiting block to drive the second limiting rod. The second limiting rod drives the second winding half shaft. The second winding half shaft drives the second T-shaped limiting slider to slide along the symmetrically set T-shaped limiting slide groove. At the same time, the limiting block drives the limiting rod. The limiting rod drives the winding half shaft. The winding half shaft drives the T-shaped limiting slider to slide along the T-shaped limiting slide groove. This allows for clamping and rotating packaging of the sleeping pants, solving the problem that the traditional bag's "square shape is difficult to adapt to small spaces". It is especially suitable for commuting, travel and other scenarios where luggage needs to be simplified.

[0017] This invention utilizes an adjusting groove to rotate a worm gear, which in turn meshes with a rotating worm wheel. This causes the worm wheel to rotate a threaded rod, resulting in a T-shaped lifting slider sliding upwards along the outer wall of the threaded rod and the inner wall of the T-shaped groove. Simultaneously, the inner wall of the T-shaped lifting slider slides along the outer wall of the spring limiting rod, thereby compressing the limiting spring upwards. This increases the thrust of the limiting spring on the T-shaped slider. Consequently, when the winding rod and the two winding rods are used to roll up the sleeping pants, the pressure of the T-shaped slider driving the limiting plate upwards on the sleeping pants increases. This ensures a stable compression effect of the limiting plate when the sleeping pants are pushed downwards during the rolling and packaging process, thus solving the problems of "loose and bulky" in traditional methods.

The top of the T-shaped lifting slider 310 is fixedly connected to the bottom of the spring limit rod 304.

[0038] The implementation principle of a roll-up and packing device for overnight pants in this application embodiment is as follows: When the roll-up component 2 inside the outer shell 1 of the roll-up and packing device is working, the drive motor 201 starts, and its output end drives the motor rotating rod 202 to rotate. The motor rotating rod 202 drives the drive disk 203 to rotate. When the drive disk 203 rotates, the T-shaped limiting slide groove 204 on its front side drives the T-shaped limiting slider 205 to rotate. The T-shaped limiting slider 205 drives the winding half shaft 206 and the winding rod 207 to rotate. At the same time, the drive disk 203 drives the T-shaped limiting slider 224 through the T-shaped limiting slide groove 204. The T-shaped limiting slider 224 drives the winding half shaft 222 and the winding rod 223 to rotate, so as to realize the roll-up action of the overnight pants. As the second winding half-shaft 222 rotates, the second winding half-shaft 206, through the avoidance and limiting groove 217 on its surface, connects to the limiting rod 216 sliding on its inner wall, thus establishing a connection between the second winding half-shaft 206 and the limiting block 215. Simultaneously, the second winding half-shaft 222, through the avoidance and limiting groove 221 on its surface, connects to the limiting rod 220 sliding on its inner wall, thus establishing a connection between the second winding half-shaft 222 and the limiting block 219. During the rotation of the second winding half-shaft 206 and the second winding half-shaft 222, the limiting rods 216 and 220 rotate along the avoidance and limiting grooves 217 and 221 respectively, avoiding obstruction. At the same time, the micro motor 208 starts, and its output end drives the bidirectional threaded rod 209 to rotate. Rod 209 drives limit gear 210 to rotate. Limit gear 210 drives limit gear 212 to rotate via synchronous rack 211. Limit gear 212 drives double threaded rod 213 to rotate, thereby causing double threaded rod 209 and double threaded rod 213 to move threaded slider 214 and threaded slider 218 inward and outward simultaneously. At the same time, threaded slider 214 and threaded slider 218 drive limit block 219 and limit block 215 to slide inward and outward simultaneously. This causes limit block 219 to drive limit rod 220. Limit rod 220 drives winding half shaft 222. Winding half shaft 222 drives T-shaped limit slider 224 to slide along the symmetrically arranged T-shaped limit groove 204. At the same time, limit block 215 drives the limit... Rod 216, the limiting rod 216 drives the winding half-shaft 206, which in turn drives the T-shaped limiting slider 205 to slide along the T-shaped limiting groove 204. This allows for clamping and rotating packaging of the sleeping pants, solving the problem of traditional bagging's "square shape being difficult to fit in small spaces." It is especially suitable for commuting, travel, and other scenarios requiring streamlined luggage. Furthermore, the worm gear 306 can be rotated via the adjusting groove 307, causing the worm gear 306 to mesh with and rotate the worm wheel 308. The worm wheel 308 then rotates the threaded rod 309, causing the T-shaped lifting slider 310 to slide upwards along the outer wall of the threaded rod 309 and the inner wall of the T-shaped groove 301. Simultaneously, the inner wall of the T-shaped lifting slider 310 slides along the outer wall of the spring limiting rod 304, thereby compressing the limiting spring 305 upwards.The increased thrust of the limiting spring 305 on the T-shaped slider 302 enhances the upward pressure exerted by the T-shaped slider 302 on the sleeping pants during the rolling-up operation of the retractor 207 and retractor 223. This increases the pressure on the sleeping pants caused by the T-shaped slider 302 driving the limiting plate 303 upwards. Consequently, when the sleeping pants are pushed downwards towards the limiting plate 303 during the rolling and packaging process, the compression effect of the limiting plate 303 on the sleeping pants is ensured, maintaining a stable compression effect. This solves the problems of "looseness and large volume" associated with traditional methods.

[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
