Description

Technical Field

[0001] This utility model relates to the field of trousers production, and in particular to an auxiliary hemming device for trousers. Background Technology

[0002] According to the patent document with publication number CN220360150U, the patent document describes a process where an adjustable connecting rod is adjusted, the screw is loosened to move the inner rod, and the screw is tightened when the rod is in the appropriate position. The trouser leg is then placed on the sleeve body, and the trouser leg is spread open by the spreading part, leaving the folded edge outside. The spreading part is heated by a heating component, and a roller moves a rotary motor to fold the arc-shaped pressing plate inward. After folding, the rotary motor drives the arc-shaped pressing plate to rotate, and the arc-shaped pressing plate tightly presses the folded edge against the inner wall of the spreading part. The heating component then stops heating, completing the folding of the trouser leg.

[0003] The patent document states that during the process of the curved pressing plate tightly pressing the folded edge against the inner wall of the spreading part by rotating, the relative movement between the curved pressing plate and the folded edge of the pants will generate friction. If the friction is too great, especially when the pressing plate is in close contact with the pants, it can easily cause the fibers on the surface of the pants to be pulled or worn, affecting the production quality of the trousers.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figures 1-10 As shown, an auxiliary folding device for trousers includes a base plate 1, a trouser support mechanism 2 is provided on one side of the top of the base plate 1, and a first folding mechanism 3 and a second folding mechanism 4. The first folding mechanism 3 is located on the other side of the top of the base plate 1, and the second folding mechanism 4 is located outside the first folding mechanism 3.

[0032] In this embodiment: the trouser support mechanism 2 includes a sleeve 201. One end of the sleeve 201 is fixed to the base plate 1 with a fixing plate. Four first sliding rods 202 are equidistantly radially slidably connected to the outer side of the other end of the sleeve 201. One end of each of the four first sliding rods 202 is fixed with a support plate 203 for opening and heating the trouser legs. A first spring 204 is fixedly connected between each of the four support plates 203 and the sleeve 201. The first spring 204 is sleeved on the outside of the first sliding rods 202. By sleeved on the outside of the trouser support mechanism 2, the trouser legs are squeezed against the three support plates 203. As a result, the three support plates 203 drive the three first sliding rods 202 to slide radially inward. The three first springs 204 are compressed and react on the three support plates 203, so that the three support plates 203 open the trouser legs.

[0033] In this embodiment: the first folding mechanism 3 includes a rotating plate 303, three second sliding rods 304 are radially slidably connected at equal distances within the rotating plate 303, and a first folding plate 305 is fixed to the end of each of the three second sliding rods 304 away from the rotating plate 303. A cylinder 301 is fixed to the top of the base plate 1, and a moving plate 302 is fixed to the telescopic end of the cylinder 301. The rotating plate 303 is rotatably connected to one side of the top of the moving plate 302. An adjusting plate 306 for driving the three second sliding rods 304 to slide radially is rotatably connected to one side of the rotating plate 303. A sliding column is fixed to the other end of each of the three second sliding rods 304. The adjusting plate 306 has three arc-shaped slots at equal distances to cooperate with the sliding columns. The rotating plate 303... A first motor is fixedly installed at the input end, and a second motor is fixedly installed at the input end of the adjusting plate 306. According to the size of the trouser leg fold, the second motor drives the adjusting plate 306 to rotate in the forward direction. The three sliding columns slide in the three arc grooves, thereby driving the three second sliding rods 304 to slide outward radially, thereby driving the three first folding plates 305 to slide to the required position. The cylinder 301 pushes the moving plate 302 to move to one side, thereby driving the three first folding plates 305 to move closer and fold the trouser leg fold inward. The first motor drives the rotating plate 303 to rotate the three first folding plates 305, pressing each part of the trouser leg fold tightly against the inner side of the three support plates 203 for heating and shaping.

[0034] In this embodiment: the second folding mechanism 4 includes three second folding plates 401, which are slidably connected to three first folding plates 305 respectively. Two second springs 402 are fixed between the second folding plates 401 and the first folding plates 305. A stopper plate 404 is fixed on the side of the second folding plate 401 near the first folding plate 305, and a lubricating box 403 is inserted into the stopper plate 404. A protective pad 405 is fixed on the side of the second folding plate 401 away from the first folding plate 305. Each of the three first folding plates 305 has a placement groove on the side away from the rotating plate 303. The lubricating box 403 is fixed in the placement groove, and the two second springs 402 are located in the placement groove. The stopper plate 404 consists of an arc plate for inserting the lubricating box 403 and a connecting plate for allowing lubricant to leak out. The second folding plates 401 have several round holes for allowing lubricant to flow out. The protective pad 405 is a soft fabric that can absorb lubricant. Three first folding plates 305 drive three second folding plates 401 to enter and fit against the folded edge of the trouser leg. The three second folding plates 401 are squeezed inward radially by the folded edge of the trouser leg inside the three support plates 203, which in turn drives the connecting plate and arc plate of the three plug plates 404 to enter the three lubrication boxes 403 respectively. The lubricant in the three lubrication boxes 403 flows out as the three second folding plates 401 rotate. The lubricant flows into the three protective pads 405 through the round holes of the three second folding plates 401, and then coats the folded edge of the trouser leg to form a lubricating film. When the three second folding plates 401 exit the folded edge of the trouser leg, the six second springs 402 release the compression and rebound, causing the three second folding plates 401 to move outward radially. Then the three plug plates 404 move out of the three lubrication boxes 403 respectively and seal them.

[0035] Working principle: The trouser legs are placed on the outside of the trouser support mechanism 2, with the folded edge of the trouser leg exposed. The trouser leg is pressed against the three support plates 203, which in turn drive the three first sliding rods 202 to slide radially inward. The three first springs 204 are compressed and react with the three support plates 203, causing the three support plates 203 to open the trouser leg. According to the size of the folded edge of the trouser leg, the second motor drives the adjusting plate 306 to rotate forward. The three sliding rods slide in the three arc grooves, which in turn drive the three second sliding rods 304 to slide radially outward. This causes the three first folding edge plates 305 to slide to the required position. The cylinder 301 pushes the moving plate 302 to move to one side, which in turn causes the three first folding edge plates 305 to move closer and fold the trouser leg edge inward.

[0036] The first motor drives the rotating plate 303 to rotate the three first folding plates 305, pressing each part of the trouser leg fold against the inner side of the three support plates 203 for heating and shaping. During this process, the three first folding plates 305 drive the three second folding plates 401 to enter and fit against the trouser leg fold. The three second folding plates 401 are squeezed inward radially by the trouser leg fold inside the three support plates 203, thereby driving the connecting plate and arc plate of the three plug plates 404 to enter the three lubrication boxes 403 respectively. The lubricant in the three lubrication boxes 403 flows out with the rotation of the three second folding plates 401. The lubricant flows into the three protective pads 405 through the round holes of the three second folding plates 401, and then is applied to the trouser leg fold to form a lubricating film.

[0037] After the folding is completed, the second motor drives the adjusting plate 306 to rotate in the opposite direction, causing the three first folding plates 305 to slide and reset, preventing the already folded trouser leg from being pulled out when the cylinder 301 drives the three first folding plates 305 to exit from the trouser leg. After the three second folding plates 401 exit the trouser leg folding, the six second springs 402 release the compression and rebound, causing the three second folding plates 401 to move radially outward. Then, the three plug plates 404 respectively move out of the three lubrication boxes 403 and seal them.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
