Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, and in particular to an automatic cutting machine for producing yoga mats. Background Art

[0002] Yoga mats are the mats that are laid underneath when practicing yoga. Yoga mats are divided into traditional yoga mats and positive yoga mats: traditional yoga mats are yoga mats without lines; positive yoga mats are yoga mats with lines, which not only have the general functions of traditional yoga mats, but also can guide the practice of more scientific and precise yoga poses. The materials of yoga mats are generally divided into rubber foam, TPE foam, PVC foam, EVA, latex mats, NBR mats, etc. The surface particles of yoga mats are uniform, the bubbles are full, the hand feels soft, and they are non-toxic, odorless, non-slip, and have strong resilience. They have strong tear resistance and are an ideal choice for yoga practitioners. In addition, yoga mats can effectively block the cold air on the ground, have strong grip, and have outstanding resilience, flatness, non-slipness, and affinity with human skin. In addition, other fitness exercises can be performed on them, which are suitable for children to play and use as mats for outdoor camping.

[0003] At present, some yoga mats with antibacterial and anti-slip functions generally have a fiber layer. When producing and processing yoga mats with fiber layers, cutting equipment is needed to cut the unrolled yoga mats into fixed lengths. However, since the fibers may be pulled and sheared during the cutting process, the fiber layer on the cut end face is relatively scattered. During transportation to the next process, the scattered fiber layer may come into contact with other surfaces of the equipment, which may cause the fiber layer to be pulled by the equipment surface or objects, thereby affecting the subsequent production of the yoga mat. Summary of the invention

[0004] In view of the fact that yoga mats with fiber layers in the prior art need to be cut to length using cutting equipment during production and processing, and the fibers may be pulled and sheared during the cutting process, resulting in a relatively scattered fiber layer on the cut end face. During transportation to the next process, the scattered fiber layer may come into contact with other surfaces of the equipment, which may cause the fiber layer to be pulled by the equipment surface or objects, thereby affecting the subsequent production of the yoga mat, an automatic cutting machine for producing yoga mats is proposed.

[0005] The present application provides an automatic cutting machine for producing yoga mats, the purpose of which is that when the cutter cuts the yoga mat, the liquid medium in the storage chamber can be sprayed from the small hole to the cut section of the yoga mat, so that the scattered fibers of the cut section are wrapped by the liquid medium, and under the action of their own weight, the scattered fibers can basically hang down, thereby minimizing the contact between the scattered fibers and the surface of the equipment or other objects, thereby reducing the phenomenon of the scattered fibers being pulled.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] Reference Figure 1-9 The present invention provides an automatic cutting machine for producing yoga mats, comprising a frame 1, brackets are welded on opposite sides of one end in the length direction of the frame 1, a winding roller 11 is connected to the two brackets for horizontal rotation, a semi-finished yoga mat is wound on the winding roller 11, a pad 9 is welded on one end of the frame 1 away from the winding roller 11, a lifting cylinder 10 is vertically installed on opposite sides of the pad 9 (corresponding to the two sides in the width direction of the frame 1), a pressing plate 2 is commonly connected to the end of the cylinder rod of the lifting cylinder 10, the pressing plate 2 is parallel to the pad 9, and the orthographic projection areas of the two coincide;

[0035] A mounting opening 20 is provided in the middle of the pad 9. Two guide columns 18 are welded horizontally on the inner walls of both sides of the mounting opening 20 corresponding to the width direction of the frame 1. The two guide columns 18 are arranged in parallel. A transverse plate 17 is installed in the mounting opening 20. The top surface of the transverse plate 17 is flush with the top surface of the pad 9. In addition, a sliding hole for the guide column 18 to slide freely is provided on the transverse plate 17. The top surface of the transverse plate 17 corresponds to both sides of the width direction of the frame 1. Baffle bars 22 are fixedly connected. The spacing between the two baffle bars 22 matches the width size of the yoga mat.

[0036] One end of the pad 9 facing the winding roller 11 is integrally fixedly connected with a receiving plate 12, and the end of the receiving plate 12 away from the pad 9 is in the form of a wedge. Both sides of the width direction of the frame 1 are welded with supports extending upward, and two drawing rollers 7 are connected to the two supports in a horizontally rotatable manner from top to bottom in sequence. A gear 8 is sleeved on one end of the drawing roller 7, and the two gears 8 are meshed, and one of the drawing rollers 7 is driven to rotate by a motor 6 installed on the support. There is a gap between the two drawing rollers 7 for the yoga mat to pass freely, and the gap is matched with the top surface of the receiving plate 12. The two drawing rollers 7 are arranged between the pad 9 and the winding roller 11;

[0037] The top of the pressing plate 2 is connected to a cylinder frame 4, and a lifting cylinder 3 is vertically installed on the top of the cylinder frame 4. The end of the cylinder rod of the lifting cylinder 3 is connected to a connecting column 13, and a storage cavity 29 is provided inside the connecting column 13. A cutter 21 is fixedly connected to the lower end of the connecting column 13. The length direction of the cutter 21 corresponds to the width direction of the yoga mat. At the same time, the length dimension of the cutter 21 is not less than the width dimension of the yoga mat. The transverse plate 17 moves along the length direction of the cutter 21 on the pad 9. A connecting cavity 29 is provided inside the cutter 21. The connecting column 13 has a through hole at the lower end thereof which is connected to the storage chamber 29 and the connecting chamber. The two surfaces of the cutter 21 in the thickness direction have a plurality of small holes 28 which are connected to the connecting chamber. The backing plate 9 has a cutter avoidance groove 16 for the cutter 21 to pass freely. A connecting pipe 27 is fixedly connected to the outer wall of the connecting column 13. The connecting pipe 27 is connected to the inside of the storage chamber 29. The connecting pipe 27 is connected to an external liquid medium delivery pump through a hose. The liquid medium may be lubricating oil or other neutral liquids.

[0038] A connecting tube 14 obliquely extending downward is fixedly connected to both radial sides of the outer wall of the connecting column 13, and a telescopic column 15 is telescopically inserted into the connecting tube 14. The telescopic column 15 telescopically slides in the connecting tube 14, and a push plate 5 is fixedly connected to the lower end of the telescopic column 15. A rubber layer (not shown in the figure) is provided on the surface of the push plate 5. The two push plates 5 are respectively located on both sides of the thickness direction of the cutter 21. A telescopic spring 30 is installed in the connecting tube 14, and the two ends of the telescopic spring 30 in the elastic force direction elastically press against the end of the telescopic column 15 and the inner wall of the connecting tube 14 respectively. A limit pin 26 is penetrated at the upper end of the telescopic column 15, and a waist-shaped hole 31 for the limit pin 26 to be inserted is opened on the periphery of the connecting tube 14. The length direction of the waist-shaped hole 31 is consistent with the telescopic sliding direction of the telescopic column 15 on the connecting tube 14.

[0039] The transverse plate 17 is rotatably connected to rollers 23 on both sides of the width direction of the frame 1, and a fixing rod 24 is vertically fixed to the bottom of the pressure plate 2. The fixing rod 24 is used in conjunction with the roller 23, and a groove 25 is provided on the surface of the fixing rod 24. A return spring 19 is wrapped around the end of the guide column 18 away from the roller 23. The two ends of the return spring 19 in the elastic force direction elastically press against the side wall of the transverse plate 17 and the inner wall of the installation opening 20 respectively and correspondingly. When the pressure plate 2 moves up and down, the elastic pressing force of the return spring 19 on the transverse plate 17 makes the roller 23 roll in contact with the surface of the fixing rod 24. As the pressure plate 2 moves up and down, the roller 23 will roll alternately on the surface of the fixing rod 24 and in the groove 25, thereby enabling the transverse plate 17 to produce a small horizontal movement.

[0040] In summary, the working principle of the present invention is as follows: the end of the yoga mat is unwound from the winding roller 11, passes between the two drawing rollers 7, and is placed on the receiving plate 12, the motor 6 is started, and drives the drawing roller 7 to rotate, and through the meshing of the two gears 8, the two drawing rollers 7 are synchronously rotated in opposite directions, and a pulling force is generated on the yoga mat, so that the yoga mat is continuously unwound from the winding roller 11, and the unwound end of the yoga mat slides on the receiving plate 12 to the transverse plate 17, and the two baffles 22 limit the two sides of the yoga mat in the width direction, and the movement When the movement reaches a suitable stroke, the lifting cylinder 10 is started again, the cylinder rod of the lifting cylinder 10 is shortened, and the pressing plate 2 is driven to move downward, so that the bottom surface of the pressing plate 2 presses the upper surface of the yoga mat, thereby flattening the yoga mat. When the pressing plate 2 moves downward, the return spring 19 elastically presses against the transverse plate 17, so that the roller 23 rolls alternately on the surface of the fixed rod 24 and the inner wall of the groove 25, so that the transverse plate 17 produces a small horizontal movement, thereby causing the yoga mat to swing slightly left and right, thereby achieving the effect of correcting the position of the yoga mat;

[0041] Then start the lifting cylinder 3, the cylinder rod of the lifting cylinder 3 extends, and drives the connecting column 13 to move downward. When the connecting column 13 moves downward, it drives the cutter 21 to move downward and cut the yoga mat. After the cutter 21 cuts, it will be stuck in the cutter avoidance groove 16 to completely cut the yoga mat. During the cutting process, the push plate 5 contacts the surface of the yoga mat before the cutter 21. As the cutter 21 continues to move downward, the push plate 5 and the yoga mat are relatively stationary, so that the telescopic column 15 slides upward in the connecting tube 14 and squeezes the telescopic spring 30, so that the telescopic spring 30 accumulates elastic potential energy. At the same time, because the connecting tube 14 is in an inclined installation state, the push plate 5 has a thrust on the yoga mat away from the cutter 21.

[0042] After the cutter 21 completely cuts the yoga mat, the ends of the two cut parts of the yoga mat will be in a state of moving away from each other under the thrust of the two pusher plates 5, so that the ends of the two cut parts are at a certain distance from the cutter 21. The external liquid medium delivery pump is started by the external control cabinet, and the liquid medium is delivered to the connecting pipe 27, then enters the storage chamber 29, and then enters the connecting chamber through the through hole, and then sprayed onto the cut section of the yoga mat through the multiple small holes 28;

[0043] Then the control cabinet stops the operation of the liquid medium delivery pump, and then the lifting cylinder 3 and the lifting cylinder 10 are started and reset in succession. After the lifting cylinder 3 is reset, the opposite ends of the two parts of the yoga mat cut off lose the pressure and thrust of the push plate 5, and will deform and reset by themselves, so that the two opposite ends (i.e., the two cut sections) are relatively close and re-fitted together, and then when the lifting cylinder 10 is reset, the roller 23 will roll alternately on the surface of the fixed rod 24 and the inner wall of the groove 25 again, so that the transverse plate 17 moves the cut part of the yoga mat horizontally, so that the cut sections of the two parts of the yoga mat slide relative to each other, and during the relative sliding, the liquid medium on the two cut sections can be evenly applied to the cut sections.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
