Description

Technical Field

[0001] This application relates to the field of auxiliary devices for trouser production, and in particular to a rolling device for producing overlapping trouser noses. Background Technology

[0002] The trouser flap, also known as a belt loop, is a structure placed around the waistband of trousers for threading a belt. Its main function is to prevent the belt from slipping down, ensuring a snug and secure fit for the trousers. It is in high demand in trouser production. Depending on the design of the trousers, trouser flaps can be made of materials such as metal and leather. However, in the clothing industry, using fabric for trouser flaps is the most widespread and in the greatest demand.

[0003] The existing trouser flap structure includes fabric and filling. The filling can be made of cotton and is set in strips. The middle of the fabric is placed on the filling, and the sides are bent and wrapped around the filling. The fabric and filling are sewn together by a sewing machine to form the trouser flap. The user sews the trouser flap onto the trouser body to complete the production of the trousers.

[0004] The aforementioned technical solutions have the following drawbacks: the production demand for trouser flaps is large, and bending the fabric and wrapping it around the filling material during production is time-consuming and labor-intensive, resulting in low production efficiency. Utility Model Content

[0005] To improve the production efficiency of trouser noses, this application provides a rolling device for producing overlapping trouser noses.

[0006] The rolling device for producing overlapping trouser noses provided in this application adopts the following technical solution:

[0007] A rolling device for producing overlapping trouser noses includes a bending device and a fixing mechanism. The bending device includes a cover plate and a guide plate with a gap between them. The edges of the cover plate and the guide plate are connected to each other to form an insertion port. The cover plate is bent on both sides to form an arc plate, which is bent to the underside of the guide plate. The fixing mechanism is used for detachable connection to a sewing machine.

[0008] By adopting the above technical solution, a fixing mechanism is set on the bending machine, allowing it to be fixed to the needle side of the sewing machine. A cover plate is set on the guide plate, bending both sides of the cover plate to form an arc plate. This results in two arc plates being bent and set on both sides of the guide plate. When the user inserts the fabric into the slot, the fabric moves and its sides abut against the inner wall of the arc plate, causing the fabric to bend. This allows the bent fabric to wrap the filling material. The user can then use the sewing machine to sew the fabric and filling material together to form a continuous trouser nose. By cutting the trouser nose, the user can mass-produce trouser noses, improving trouser nose production efficiency.

[0009] Optionally, a clearance groove is provided on the cover plate, the clearance groove penetrates the cover plate, and the length direction of the clearance groove is parallel to the length direction of the bending machine.

[0010] By adopting the above technical solution, by opening a clearance groove on the cover plate, when the fabric is inserted into the bending machine, the fabric is exposed in the clearance groove, and the user can move the fabric to adjust the position of the fabric, so that the fabric can extend and move along the length direction of the bending machine.

[0011] Optionally, the guide plate is provided with multiple side plates, which are located outside the insertion port and are used to limit the movement of the fabric.

[0012] By adopting the above technical solution and setting side plates on the guide plate, when the fabric is inserted into the slot, the fabric is located between the two side plates. The side plates play a guiding role, which can reduce the probability of the fabric shifting position during bending and improve the production quality of the trouser nose.

[0013] Optionally, the guide plate has a bevel, which extends along the connection between the cover plate and the arc plate.

[0014] By adopting the above technical solution, by opening a sloping surface on the guide plate, the sloping surface has a large surface area. When the fabric is bent between the cover plate and the guide plate, the guide plate provides support for the middle of the fabric, so that the fabric can be bent flat with fewer wrinkles on the fabric surface.

[0015] Optionally, the bender is positioned above the fixed mechanism.

[0016] By adopting the above technical solution, when the bending coil is fixed to the sewing machine's worktable by the fixing mechanism, the bending coil is higher than the sewing machine's worktable. The user can set a continuous strip of stuffing material below the guide plate. When the sewing machine sews the stuffing material and the fabric, the fabric moves inside the bending coil and continuously wraps the stuffing material.

[0017] Optionally, the fixing mechanism includes a fixing plate and a base plate. The fixing plate is welded and fixed to the bending machine. Bolt 1 is provided on the fixing plate. The base plate is fixed to the fixing plate by bolt 1. Bolt 2 is provided on the base plate. The base plate is fixed to the sewing machine by bolt 2.

[0018] By adopting the above technical solution, a fixing plate is set on the bending machine, making the fixing plate and the base plate detachably connected. By fixing the base plate on the sewing machine, the bending machine can be fixed on the sewing machine. When the continuous fabric or filling is used up, the user can put new fabric into the bending machine by removing the fixing plate from the base plate.

[0019] Optionally, a waist hole 1 is provided on the fixing plate, and a bolt 1 is installed in the waist hole 1. A waist hole 2 is provided on the bottom plate, and a bolt 2 is installed in the waist hole 2.

[0020] By adopting the above technical solution, by setting a waist hole one on the fixed plate and a waist hole two on the base plate, bolt one can slide in waist hole one, thereby facilitating the user to adjust the position of the sewing machine sewing the fabric and filling.

[0021] Optionally, the length direction of waist hole one is perpendicular to that of waist hole two.

[0022] By adopting the above technical solution, and setting the first waist hole and the second waist hole to be perpendicular to each other, it is convenient for users to adjust the position of the bending machine.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By setting a fixing mechanism on the bending machine, the bending machine can be fixed to the needle side of the sewing machine. By setting a cover plate on the guide plate, the two sides of the cover plate are bent to form an arc plate, so that the two arc plates are bent on both sides of the guide plate. When the user inserts the fabric into the slot, the two sides of the fabric abut against the inner wall of the arc plate when the fabric moves, so that the two sides of the fabric are bent. In this way, the bent fabric can wrap the filling. The user can use the sewing machine to sew the fabric and filling to form a continuous trouser nose. By cutting the trouser nose, the user can mass-produce trouser noses and improve the production efficiency of trouser noses.

[0025] 2. By opening a clearance groove on the cover plate, when the fabric is inserted into the bending machine, the fabric is exposed in the clearance groove, and the user can move the fabric to adjust the position of the fabric, so that the fabric can extend and move along the length direction of the bending machine.

[0026] 3. By setting a fixing plate on the bender, the fixing plate and the base plate can be detachably connected. By fixing the base plate to the sewing machine, the bender can be fixed to the sewing machine. When the continuous fabric or filling is used up, the user can put new fabric into the bender by removing the fixing plate from the base plate. Attached Figure Description

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses a rolling device for producing overlapping trouser flaps, referring to... Figure 1 , Figure 2 and Figure 3 The device includes a bending device 1 and a fixing mechanism 2. The bending device 1 includes a cover plate 11 and a guide plate 12, with a gap between them. The side edges of the cover plate 11 and the guide plate 12 are connected to each other. The bending device 1 has different widths at both ends along its length. The fabric is inserted from the wider side of the bending device 1, inserted straight into the bending device 1 and moved. The two ends of the fabric can be bent and folded, thereby wrapping the filling material and forming a trouser nose structure. The cover plate 11 is bent to form two arc plates 111, with the edges of the arc plates 111 located below the guide plate 12. When the strip of fabric is inserted into the bending device 1, the fabric moves between the cover plate 11 and the guide plate 12. The sides of the fabric abut against the arc plates 111 and bend, thereby folding the two sides of the fabric. A strip of filling material can be placed below the guide plate 12, and the fabric can wrap the filling material and extend out of the bending device 1. A fixing mechanism 2 is connected to the cover plate 11. The fixing mechanism 2 is used to fix the curling coiler 1 to one side of the sewing machine needle, so that the sewing machine can sew the fabric and filling to form a strip-shaped trouser nose. The user can then further cut the trouser nose and sew it onto the trouser body to complete the production of the trousers.

[0035] Reference Figure 1 The cover plate 11 has a clearance groove 112, the length direction of which is parallel to the length direction of the cover plate 11, and the clearance groove 112 extends through the cover plate 11. When the fabric is inserted into the cover plate 11, the user can adjust the position of the fabric through the clearance groove 112, causing the fabric to bend and extend out of the bending machine 1. The guide plate 12 is provided with two connectors 121, which, together with the cover plate 11 and the guide plate 12, form a frame structure and an insertion port 113. The fabric is inserted into the insertion port 113 and moves within the bending machine 1. In other embodiments, the cover plate 11 and the guide plate 12 are fixed to each other by welding.

[0036] Reference Figure 3 and Figure 4The guide plate 12 is provided with multiple side plates 122, which are located on one side of the insertion port 113. When the fabric is inserted into the insertion port 113, the side plates 122 limit the movement of the fabric, reducing the chance of the fabric slipping inside the bending machine 1. The guide plate 12 has a sloping surface 123, which extends along the connection between the cover plate 11 and the arc plate 111. The guide plate 12 is located below the cover plate 11, providing support for the fabric and keeping it flat after folding, thus improving the production quality of the trouser loops.

[0037] Reference Figure 5 In other embodiments, a through groove is provided on the cover plate 11, and a roller 3 is rotatably connected in the through groove. The roller 3 is made of elastic rubber material, which can reduce the wear of the roller 3 on the fabric surface when it abuts against the fabric located between the cover plate 11 and the guide plate 12. The upper side of the roller 3 is set higher than the cover plate 11, and the lower end of the roller 3 is located between the cover plate 11 and the guide plate 12. The axis of the roller 3 is perpendicular to the length direction of the guide plate 12. When the user inserts the fabric into the space between the cover plate 11 and the guide plate 12, the fabric is prone to wrinkling and accumulating between the cover plate 11 and the guide plate 12, making it difficult for the fabric to slide out. By rotatably connecting the roller 3 on the cover plate 11, the user can rotate the roller 3 to press the roller 3 against the fabric surface and move the fabric, thus making it convenient for the user to place the fabric between the cover plate 11 and the guide plate 12.

[0038] Reference Figure 1 The fixing mechanism 2 includes a fixing plate 21 and a base plate 22. The fixing plate 21 is fixed to one side of the cover plate 11 by welding, and the base plate 22 is detachably connected to the fixing plate 21. The fixing plate 21 has a first waist hole 211, in which multiple first bolts 212 are installed. The first bolts 212 are inserted into the first waist hole 211 and threadedly connected to the base plate 22. The fixing plate 21 and the base plate 22 are adjusted relative to each other using the first bolts 212, thus facilitating the adjustment of the position of the coil bending device 1 on the sewing machine. The base plate 22 has multiple second waist holes 221, the length direction of which is perpendicular to the length direction of the first waist hole 211. Multiple second bolts 222 are installed in the second waist holes 221, and the second bolts 222 are threadedly fixed to the sewing machine. The user can slide the coil bending device 1 along the length directions of the first waist hole 211 and the second waist hole 221 respectively, facilitating the adjustment of the fabric position and sewing.

[0039] The implementation principle of this application embodiment is as follows: by setting a fixing mechanism 2 on the bending roller 1, the fixing mechanism 2 can fix the bending roller 1 on the sewing machine. The user inserts the fabric into the insertion port 113 and places the filling material below the guide plate 12, so that the fabric can be bent and wrap the filling material in the bending roller 1. During the process of the user sewing the fabric and the filling material with the sewing machine, the strip-shaped fabric continuously bends through the bending roller 1 and overlaps on the filling material, which makes it convenient for the user to continuously process the trouser nose.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
