Description

Technical Field

[0001] The utility model relates to the field of bedding, in particular to a peripheral cutting device. Background Art

[0002] Bedding is items placed on the bed for people to use when sleeping, including quilts, duvet covers, sheets, bedspreads, fitted sheets, pillowcases, etc. Most of these items are surrounded by borders.

[0003] The production of the edge usually goes through the processes of cutting, copying and temporary storage. In the current production mode, the cutting step is mostly done manually, which has the following defects:

[0004] Firstly, since the materials of the edging are mostly cloth, leather, etc., which have a certain degree of elasticity, they are stored in rolls or stacked. Manual cutting requires human pulling, and the actual cut length depends on the experience of the staff (the influencing factors include the amount of force, the pulling method, and the pulling process), which makes it difficult to unify the cut length of the edging.

[0005] Secondly, after manual cutting, they need to be stored and transferred manually, which takes up a lot of labor and space.

[0006] Third, manual cutting is inefficient, which seriously restricts the processing efficiency of the edge. Utility Model Content

[0084] Working principle and usage:

[0085] The first step is pre-setting:

[0086] Press the start switch to power on the device and adjust the preset value according to the length of the edge (i.e. the product to be processed).

[0087] The second step is loading and cutting.

[0088] Place the edge to be cut under the anti-sliding block of the "G"-shaped movable traction plate 205, press the cutting switch, and the PLC controller outputs a signal to the electromagnet 207, the push rod motor 202, and the screw stepper motor 204.

[0089] The electromagnet 207 on the left side is started to clamp one end of the edge, and the screw stepper motor 204 delays to drive the edge to move right. When the "G"-shaped movable traction plate 205 passes the distance sensor module 1, the PLC controller controls the push rod motor 202 to start, driving the pressing roller 203 to move downward, thereby completing the fixation of the edge.

[0090] When the screw stepper motor 204 drives the edge to run to a preset distance, the PLC controller outputs a signal to the electric telescopic rod 301 and the servo motor 302; the servo motor 302 starts, causing the cutting knife 303 to start running, and the electric telescopic rod 301 delays and drives the cutting knife 303 to move backward in an orderly manner, thereby completing the cutting of the edge.

[0091] Afterwards, the electric telescopic rod 301 drives the cutting knife 303 to reset.

[0092] The third step is transfer and material collection:

[0093] After the cutting is completed, the PLC controller outputs signals to the screw stepper motor 2 401 , the screw stepper motor 3 403 , the push rod motor 2 404 , and the clamping jaw motor 405 .

[0094] The screw stepper motor 2 401 drives the "L"-shaped detection rod 402 to approach the side of the edge in an orderly manner. When the distance sensor module 2 detects the edge, the distance sensor module 3 outputs the width signal of the edge to the PLC controller. After that, the screw stepper motor 2 401 drives the "L"-shaped detection rod 402 to approach the edge, and through the limit column 107 (shortening the distance between the "L"-shaped detection rod 402 and the limit column 107), the width occupied by the edge is squeezed to facilitate the gripping of the gripper motor 405.

[0095] The push rod motor 404 drives the clamping jaw motor 405 to move downward, and the clamping jaw motor 405 delays to clamp the edge; the push rod motor 404 resets, and the screw stepping motor 403 delays to drive the edge to be transported to the top of the corresponding storage box 504 through the push rod motor 404; then, the push rod motor 404 drives the clamping jaw motor 405 to move downward. The clamping jaw motor 405 delays to release.

[0096] When the material picking switch is pressed, the PLC controller outputs a signal to the screw stepper motor four 501; the screw stepper motor four 501 drives the storage box 504 to move to one side of the rectangular through hole two, so as to facilitate unloading of the storage box 504.

[0097] Embodiment 2, based on embodiment 1, an "L"-shaped limit rod is additionally provided on the cutting seat 102, and a movable limit plate is bolted to the "L"-shaped limit rod to improve the entry position accuracy of the surrounding edge.
