Description

Technical Field

[0001] This utility model belongs to the field of trouser manufacturing technology, specifically relating to a cutting device for making waistbands. Background Technology

[0002] Trousers, generally referring to clothing worn below the waist, are typically made of a waistband, crotch, and legs sewn together. Some trousers also have waist loops to secure the belt. The production process of waist loops usually includes the following steps: folding a long strip of fabric and sewing it along its length; then cutting the sewn long strip into several short strips of the same length.

[0003] In the current process of making waistbands, long strips of fabric are mainly cut manually. Manual cutting is not only tedious and inefficient, but it also requires workers to concentrate, which can easily lead to worker fatigue and eye strain. Since the cutting effect of manual cutting depends on the worker's working condition, and workers cannot maintain a stable working condition for a long time, the cut strips of fabric may be inconsistent in length or have slanted edges, affecting subsequent processing and the appearance of the finished pants. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a cutting device for making trouser loops that ensures cutting quality and reduces the labor intensity of workers.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a cutting device for making waist loops, including a worktable, on which a transport section, a cutting section and a rear clamping section are provided. The transport section and the rear clamping section are respectively arranged on both sides of the cutting section. The transport section includes rollers and a driving member for driving the rollers to rotate. There are two rollers and their side walls abut against each other. The cutting section includes a fixed blade fixed to the worktable, a movable blade arranged on the side of the fixed blade away from the worktable, and a driving member for controlling the movable blade to move towards the fixed blade.

[0006] Using the above scheme, in actual use, the sewn long strip of fabric is placed between the two rollers. The rollers rotate under the action of the first drive unit, passing between the fixed and movable blades, and then reaching the rear clamping part. The rollers stop rotating after a predetermined number of revolutions to prevent further movement of the long strip of fabric. The rear clamping part then clamps the long strip of fabric. Subsequently, the movable blade moves towards the fixed blade under the action of the second drive unit until the long strip of fabric is cut. The cut short strips of fabric can be removed by the worker, or a collection structure for collecting the short strips can be provided on the side of the rear clamping part away from the cutting part.

[0007] Compared with existing technologies, this invention improves cutting efficiency while ensuring that the cut strips of fabric are uniform in shape and length. It also reduces manual labor in the production of trouser loops, lowers the workload of workers, and ensures their health.

[0008] As a further feature of this utility model, the rear clamping part includes a lower moving end, an upper moving end disposed on the side of the lower moving end away from the worktable, a third driving member for controlling the upper moving end to move away from the lower moving end, a fourth driving member for controlling the third driving member to move away from the cutting part, and a fifth driving member for controlling the lower moving end to move away from the cutting part.

[0009] Using the above scheme, when a long strip of fabric needs to pass through, there is a gap between the upper and lower moving ends to allow the long strip of fabric to pass. When it is necessary to fix the long strip of fabric, the upper moving end moves to the lower moving end under the action of the driving component four until the long strip of fabric is clamped. After the long strip of fabric is clamped, the driving components four and five act simultaneously, causing the upper and lower moving ends to move a certain distance away from the cutting part, so that the long strip of fabric between the movable and fixed blades is taut, facilitating cutting.

[0010] As a further feature of this utility model, a front clamping part is provided between the transport part and the cutting part. The front clamping part includes a fixed end fixed to the worktable, a movable end provided on the side of the fixed end away from the worktable, and a driving member six for controlling the movable end to move towards the fixed part.

[0011] Using the above solution, when a long strip of fabric needs to pass through, there is a gap between the movable end and the fixed end to allow the long strip of fabric to pass. When it is necessary to fix the long strip of fabric, the movable end moves towards the movable end under the action of the drive component six until the long strip of fabric is clamped. The front clamping part and the rear clamping part clamp together to achieve a better clamping and fixing effect. Moreover, the transition through the fixed end allows the long strip of fabric to move more smoothly.

[0012] As a further feature of this invention, a guide cavity is provided on the side of the transport section away from the cutting section. The distance between the two cavity walls of the guide cavity that are perpendicular to the worktable increases as the distance from the transport section increases. A window communicating with the outside is provided on the cavity wall of the guide cavity away from the worktable.

[0013] Using the above solution, the guide cavity can organize the twisted long fabric, ensuring smooth subsequent cutting. The window facilitates worker inspection and also makes it easy to place the end of the long strip of fabric between the two rollers.

[0014] As a further feature of this invention, the worktable is provided with a collection hole, which is located on the side of the rear clamping part away from the cutting part.

[0015] Using the above scheme, it is preferable that the length of the long strip of fabric located at the rear clamping part away from the cutting part during cutting is greater than the length between the front clamping part and the rear clamping part. After cutting, the short strip of fabric falls into the collection hole under the action of gravity. If the short strip of fabric fails to fall successfully, the long strip of fabric will push the cut short strip of fabric into the collection hole during the subsequent rotation of the roller.

[0016] The collection port can lead to a collection basket or a conveyor belt connected to subsequent processes.

[0017] As a further feature of this invention, the workbench is provided with two parallel retaining walls, and the transport section, the front clamping section, the cutting section and the rear clamping section are all located between the two retaining walls.

[0018] Using the above scheme, the retaining wall is used to ensure the direction of movement of the long strip of cloth.

[0019] As a further feature of this invention, the sidewall of the roller, the surface of the movable end facing the fixed end, and the surface of the upper moving end facing the lower moving end are all covered with an anti-slip layer made of elastic material.

[0020] Using the above solution, the anti-slip layer on the roller can better drive the long strip of cloth to move, and the anti-slip layers on the movable end and the upper movable end can better fix the long strip of cloth.

[0021] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Specific embodiments of this utility model are shown in the accompanying drawings.

[0029] A cutting device for making waist loops includes a workbench 1. The workbench 1 is provided with a transport section 2, a cutting section 3, a rear clamping section 4 and a front clamping section 5. The front clamping section 5 and the rear clamping section 4 are respectively arranged on both sides of the cutting section 3. The transport section 2 is arranged on the side of the front clamping section 5 away from the cutting section 3.

[0030] The transport section 2 includes rollers 21 and a drive member 22 for rotating the rollers 21. There are two rollers 21 with their sidewalls abutting each other. The cutting section 3 includes a fixed blade 31 fixed to the worktable 1, a movable blade 32 located on the side of the fixed blade 31 away from the worktable 1, and a drive member 33 for controlling the movable blade 32 to move towards the fixed blade 31. The rear clamping section 4 includes a lower moving end 41, an upper moving end 42 located on the side of the lower moving end 41 away from the worktable 1, a drive member 43 for controlling the upper moving end 42 to move away from the lower moving end 41, a drive member 44 for controlling the drive member 43 to move away from the cutting section 3, and a drive member 45 for controlling the lower moving end 41 to move away from the cutting section 3. The front clamping section 5 includes a fixed end 51 fixed to the worktable 1, a movable end 52 located on the side of the fixed end 51 away from the worktable 1, and a drive member 53 for controlling the movable end 52 to move towards the fixed end.

[0031] In actual use, the sewn long strip of fabric is placed between the two rollers 21. At this time, there is a gap between the upper moving end 42 and the lower moving end 41 for the long strip of fabric to pass through, and there is also a gap between the movable end 52 and the fixed end 51 for the long strip of fabric to pass through. The rollers 21 rotate under the action of the drive component 22, and the long strip of fabric moves more smoothly through the transition of the fixed end 51. After passing through the front clamping part 5, the long strip of fabric passes between the fixed blade 31 and the movable blade 32, and then reaches the rear clamping part 4. After the roller 21 rotates a predetermined number of times, it stops to prevent the long strip of fabric from moving further. The upper moving end 42 moves to the lower moving end 41 under the action of the driving member 44 until the long strip of fabric is clamped. The movable end 52 moves towards the movable end 52 under the action of the driving member 53 until the long strip of fabric is clamped. Then, the driving members 44 and 55 act simultaneously, causing the upper moving end 42 and the lower moving end 41 to move a certain distance away from the cutting part 3, thus tautning the long strip of fabric between the movable blade 32 and the fixed blade 31. Subsequently, the movable blade 32 moves towards the fixed blade 31 under the action of the driving member 33 until the long strip of fabric is cut.

[0032] Compared with existing technologies, this embodiment ensures that the cut strips of fabric are uniform in shape and length, while improving cutting efficiency. It also reduces manual intervention in the production process of trouser loops, lowers the workload of workers, and ensures their health.

[0033] In this embodiment, drive component 1 22 is a rotary motor, drive component 2 33, drive component 3 43 and drive component 6 53 are electric telescopic rods, and drive component 44 and drive component 5 45 are electric lead screws.

[0034] A guide cavity 6 is provided on the side of the transport section 2 away from the cutting section 3. The distance between the two cavity walls of the guide cavity 6 that are perpendicular to the worktable 1 increases as it moves away from the transport section 2. A window 61 communicating with the outside is provided on the cavity wall of the guide cavity 6 away from the worktable 1. The guide cavity 6 can organize twisted long fabrics to ensure smooth subsequent cutting. The window 61 facilitates worker inspection and also makes it easy to place the end of the long fabric strip between the two rollers 21.

[0035] The workbench 1 is equipped with a collection hole 11, which is located on the side of the rear clamping part 4 away from the cutting part 3. In this embodiment, during cutting, the length of the long strip of fabric in the rear clamping part 4 away from the cutting part is greater than the length between the front clamping part 5 and the rear clamping part 4. After cutting, the short strip of fabric falls into the collection hole 11 under the action of gravity. If the short strip of fabric fails to fall, the long strip of fabric will push the cut short strip of fabric into the collection hole 11 during the subsequent rotation of the roller 21. The collection hole 11 can lead to a collection basket or a conveyor belt connected to subsequent processes.

[0036] The workbench 1 is equipped with two parallel retaining walls 7. The transport section 2, the front clamping section 5, the cutting section 3, and the rear clamping section 4 are all located between the two retaining walls 7. The retaining walls 7 are used to ensure the direction of movement of the long strip of fabric.

[0037] The sidewalls of roller 21, the surface of movable end 52 facing fixed end 51, and the surface of upper moving end 42 facing lower moving end 41 are all covered with an anti-slip layer made of elastic material. The anti-slip layer on roller 21 can better drive the long strip of cloth to move, and the anti-slip layers on movable end 52 and upper moving end 42 can better fix the long strip of cloth.

[0038] This utility model is not limited to the specific embodiments described above. Those skilled in the art can implement this utility model using other specific embodiments based on the content disclosed in this utility model. Any simple changes or modifications made to the design structure and concept of this utility model will fall within the protection scope of this utility model.
