Description

Technical Field

[0001] This utility model relates to the field of textile testing technology, and in particular to a test fabric shredder. Background Technology

[0002] In the field of testing technology, the conventional approach to testing various textile fabrics, sheet products, and materials for harmful components and pH values ​​involves manually breaking the fabric products into very small sizes, then using solvents to extract or separate the chemical components to be tested, purifying them, weighing them, and obtaining the test results.

[0003] The usual method for breaking down fabric products is to do it manually with scissors, cutting the fabric into pieces for testing. The drawbacks of manual operation are obvious: not only is the cutting work laborious and repetitive, but the pieces are also of varying sizes, which directly affects the accuracy of the testing process. Utility Model Content

[0004] The purpose of this invention is to provide a test fabric shredder that can automatically shred test fabric into small, equal-sized pieces using a movable roller and a movable, rotating worktable, thereby improving testing accuracy, shredding efficiency, and shredding stability.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A test fabric shredder includes a frame, a movable and rotatable worktable at the lower part of the frame, a rubber pad on the worktable, a roller cutter above the rubber pad, and a drive mechanism for driving the roller cutter to lift and move.

[0007] Using the above technical solution, the test fabric is laid flat on a rubber mat, and the roller cutter is moved down so that its lower edge is against or below the upper surface of the rubber mat. Then the roller cutter moves left and right to cut the fabric. When the roller cutter moves to its limit position to the left or right, the roller cutter moves up to detach from the fabric, and the worktable moves a certain distance to cut the fabric into strips of equal width.

[0008] Then the worktable rotates 90 degrees, and the fabric on the rubber pad also rotates 90 degrees. The roller cutter moves left and right in a cycle. When the roller cutter reaches its limit position, it moves up and detaches from the fabric. Then the work platform moves a certain distance horizontally, thereby cutting the strip of fabric into multiple small pieces of fabric.

[0009] Preferably, the bottom of the worktable is fixed with a rotating shaft, which is rotatably connected to the slide. The slide is fixed on the slider of the Y-axis linear module, and the Y-axis linear module is fixed on the frame.

[0010] A gear coaxially mounted on the rotating shaft is fixed thereon, the gear meshing with a rack, the rack being fixed to the end of the telescopic rod of the telescopic cylinder, and the telescopic cylinder being fixed to the slide table. Both the Y-axis linear module and the telescopic cylinder are electrically connected to the controller.

[0011] The Y-axis linear module can drive the slider to move along the Y-axis, i.e., move back and forth. The telescopic cylinder drives the rack to move, the rack drives the gear to rotate, and the gear drives the worktable to rotate through the rotating shaft, thereby realizing the translation and rotation of the worktable.

[0012] Preferably, the worktable includes a square base plate, with a right-angled protrusion formed at each of the four corners of the square base plate; the rubber pad is placed between the four right-angled protrusions, thereby restricting the position of the rubber pad; the upper surface of the rubber pad is set higher than the right-angled protrusions, which can effectively prevent the hob from colliding with the worktable.

[0013] Preferably, the rubber pad is detachably connected to the worktable, and a groove is formed in the center of each of the four sides of the square base plate, so that the rubber pad can be easily removed from the worktable through the groove.

[0014] Preferably, the driving mechanism includes an X-axis linear module, a sliding seat is fixed on the slider of the X-axis linear module, multiple connecting rods are sleeved on the sliding seat, the lower ends of the connecting rods are fixed on the hob holder, and the hob is rotatably connected to the hob holder through a support shaft;

[0015] The hob holder and the sliding seat are connected by a pressure sensor;

[0016] The X-axis linear module is fixed on the telescopic rod of the Z-axis telescopic cylinder, which is fixed on the upper part of the frame. Both the pressure sensor and the Z-axis telescopic cylinder are electrically connected to the controller.

[0017] The Z-axis telescopic cylinder drives the X-axis linear module to achieve lifting and lowering. The slider of the X-axis linear module drives the roller cutter seat and roller cutter to move, thereby achieving translation. The pressure sensor can detect the magnitude of the supporting force of the rubber plate on the roller cutter. When the roller cutter moves downward, it presses against the rubber plate. The magnitude of the reaction force on the roller cutter determines the extent of the downward movement of the roller cutter.

[0018] Preferably, the roller cutter is formed with multiple axially evenly distributed ring cutters, and multiple ring cutters can cut multiple strips of fabric at once.

[0019] Preferably, the lower ends of the plurality of ring cutters of the roller are inserted into the relief groove of the pressing plate;

[0020] Guide rods are fixed at both ends of the pressure plate. The upper end of the guide rod is inserted into the guide tube, which is fixed to the end of the X-direction linear module. A compression spring is clamped between the lower end of the guide tube and the pressure plate.

[0021] The pressure plate first contacts the fabric with the roller cutter, thus pressing the fabric tightly to ensure the cutting quality of the fabric. When the worktable moves, the pressure plate needs to be detached from the test fabric by the Z-axis telescopic cylinder.

[0022] The outstanding effect of this utility model is:

[0023] Compared with existing technologies, the test fabric can be automatically broken into small pieces of equal size by a movable roller and a movable, rotating worktable, which improves the detection accuracy, fabric breaking efficiency and fabric breaking stability.

[0024] By setting multiple ring cutters on the roller cutter, the crushing efficiency can be further improved. Attached Figure Description

Then the roller cutter moves left and right to cut the fabric. When the roller cutter moves to its limit position to the left or right, the roller cutter moves up to detach from the fabric, and the worktable moves a certain distance to cut the fabric into strips of equal width.

[0042] Then the worktable rotates 90 degrees, and the fabric on the rubber pad also rotates 90 degrees. The roller cutter moves left and right in a cycle. When the roller cutter reaches its limit position, it moves up and detaches from the fabric. Then the work platform moves a certain distance horizontally, thereby cutting the strip of fabric into multiple small pieces of fabric.
