Description

Technical Field

[0001] The invention relates to the technical field of non-woven fabric cutting, in particular to a cross-section cutting machine applied to non-woven fabrics. Background Art

[0002] The main materials of non-woven fabrics include polypropylene fiber, polyester fiber, polyamide fiber, polyacrylonitrile fiber and viscose fiber. It is a non-woven fabric made by directional or randomly arranged fibers through friction, cohesion, bonding or a combination of these methods. Non-woven fabrics are light, soft, breathable, water-repellent, non-toxic and non-irritating. They are environmentally friendly materials and are widely used in shopping bags, wallpapers, medical supplies and other fields. Unlike traditional textile fabrics, non-woven fabrics do not need to go through the process of spinning and weaving, but directly pass the fibers through airflow or mechanical webs, and then reinforce them into shape. In order to facilitate the production and sales of non-woven fabrics, non-woven fabrics need to be cut. After traditional cutting, the gravity of the non-woven fabric will cause the cutting surface to bend and deform, which will affect the subsequent material guide. Therefore, an additional support mechanism needs to be set at the bottom, resulting in a complex structure. At the same time, the non-woven fabric cannot be tightened in four directions before cutting, resulting in low cutting accuracy. The non-woven fabric after cutting cannot be high-temperature shaped, resulting in very limited flatness of the cutting surface. Summary of the invention

[0003] The technical problem to be solved by the present invention is that traditional non-woven fabrics will bend and deform due to gravity after cutting, which will affect the subsequent material guiding and require additional supporting mechanisms, resulting in a complex structure. At the same time, the non-woven fabric cannot be stretched in four directions before cutting, resulting in low cutting accuracy. The non-woven fabric cannot be high-temperature shaped after cutting, resulting in very limited flatness of the cut surface.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a cross-section cutting machine applied to non-woven fabrics, comprising a main frame, an embedded electric control adjustment disk is installed on the side wall of the main frame, two groups of electric control cloth guide rollers are installed on the outer side of the embedded electric control adjustment disk, a first electric control cutting blade and a second electric control cutting blade are installed on the outer side of the embedded electric control adjustment disk, a heat circulation flow channel is arranged inside the embedded electric control adjustment disk and the electric control cloth guide roller, and an internal circulation heating module matched with the heat circulation flow channel is fixedly installed inside the main frame.

[0005] A circular sinking groove matched with the embedded electric control adjustment disk is provided on the outer side surface of the main frame, and an internal guide hole is provided at the center position of the inner side surface of the circular sinking groove.

[0006] The embedded electric control adjustment disk comprises an embedded assembly disk movably installed inside the circular sinking groove, an embedded adjustment motor fixed inside the circular sinking groove, a lateral adjustment ring fixed on the inner side of the embedded assembly disk, and a lateral adjustment gear meshing with the outer tooth surface of the lateral adjustment ring.

[0007] A lateral assembly frame for mounting an electrically-controlled cloth guide roller and a lateral installation frame for mounting a first electrically-controlled cutting blade and a second electrically-controlled cutting blade are fixed on the outer side of the embedded assembly disk.

[0009] The first and second electrically controlled cutting blades include a flip assembly frame movably assembled with the inner side of the lateral mounting frame, a replaceable blade fixed inside the flip assembly frame, and an adjusting support rod movably mounted inside the lateral mounting frame.

[0010] The internal circulation heating module comprises a fixed air deflector fixedly installed inside the main frame, an electrically controlled centrifugal pump movably installed inside the fixed air deflector, and an arc-shaped electric heating frame installed on the inner arc surface of the fixed air deflector.

[0011] The heat circulation flow channel includes a first flow guide channel and a first return flow channel opened in the main frame, a second flow guide channel and a second return flow channel opened in the lateral assembly frame, a third flow guide channel and a third return flow channel opened in the embedded assembly plate, and a fourth flow guide channel opened in the electric-controlled cloth guide roller.

[0012] The outer sides of the inner driving roller and the inner driven roller are provided with outwardly protruding oblique tension sleeves.

[0014] The beneficial effects of the present invention are:

[0017] (3) A heat circulation channel is provided inside the embedded electric control adjustment plate and the electric control cloth guide roller, and an internal circulation heating module matched with the heat circulation channel is fixedly installed inside the main frame, which can conduct heat inside and improve the flattening effect;

[0018] (4) The method of horizontal placement during daily transportation and vertical placement during cutting can reduce the resistance of daily transportation and reduce energy consumption;

[0019] (5) The first electric-controlled cutting blade and the second electric-controlled cutting blade are flipped and attached to the outer surface of the embedded electric-controlled adjustment disk when not in use, which is convenient for later maintenance and replacement;

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Figure 1 , Figure 2 and Figure 3The cross-section cutting machine shown is applied to non-woven fabrics, comprising a main frame 1, an embedded electric control adjustment disk 2 is installed on the side wall of the main frame 1, two groups of electric control cloth guide rollers 3 are installed on the outer side of the embedded electric control adjustment disk 2, a first electric control cutting blade 4 and a second electric control cutting blade 5 are installed on the outer side of the embedded electric control adjustment disk 2, a heat circulation flow channel 6 is arranged inside the embedded electric control adjustment disk 2 and the electric control cloth guide roller 3, and an internal circulation heating module 7 matched with the heat circulation flow channel 6 is fixedly installed inside the main frame 1.

[0029] Working principle: Under normal circumstances, the non-woven fabric is guided by two sets of electrically controlled cloth guide rollers 3 located on both sides of the outer side of the embedded electrically controlled adjustment disk 2. The relative positions of the two sets of electrically controlled cloth guide rollers 3 can be adjusted according to the different guiding angles. During transportation, the electrically controlled cloth guide rollers 3 located at the inlet end between 1 o'clock and 5 o'clock have the function of straightening the non-woven fabric forward and backward while guiding the fabric, while the electrically controlled cloth guide rollers 3 located at the outlet end between 7 o'clock and 11 o'clock play the role of heating, shaping and curing. When cutting is required, the embedded electrically controlled adjustment disk 2 rotates counterclockwise, the electrically controlled cloth guide rollers 3 located at the inlet end between 1 o'clock and 5 o'clock turn to the 12 o'clock direction, and the electrically controlled cloth guide rollers 3 located at the outlet end between 7 o'clock and 11 o'clock turn to the 6 o'clock direction. Then the first electrically controlled cutting blade 4 and the second electrically controlled cutting blade 5 are started, and then the non-woven fabric is cut by the first electrically controlled cutting blade 4 and the second electrically controlled cutting blade 5.

[0030] In order to cooperate with the lateral installation, a circular sinking groove 8 matching with the embedded electric control adjustment disk 2 is opened on the outer side surface of the main frame 1, and an internal guide hole 9 is opened at the center position of the inner side surface of the circular sinking groove 8.

[0031] In order to cooperate with lateral assembly adjustment, the embedded electric control adjustment disk 2 includes an embedded assembly disk 21 movably installed inside the circular sinking groove 8, an embedded adjustment motor 22 fixed inside the circular sinking groove 8, a lateral adjustment ring 23 fixed on the inner side of the embedded assembly disk 21, and a lateral adjustment gear 24 meshing with the outer tooth surface of the lateral adjustment ring 23.

[0032] The embedded adjustment motor 22 drives the lateral adjustment gear 24 to rotate, and then the lateral adjustment gear 24 drives the lateral adjustment ring 23 to rotate. At this time, the embedded assembly disk 21 will rotate inside the circular sinking groove 8, thereby adjusting the positions and angles of the two sets of electrically-controlled cloth guide rollers 3, the first electrically-controlled cutting blade 4 and the second electrically-controlled cutting blade 5.

[0033] The embedded assembly plate 21 is inserted into the internal flow guide hole 9 through the flow guide pipe at the inner center position and is movably installed in the circular sinking groove 8.

[0034] In order to cooperate with external installation, a lateral assembly frame for mounting the electrically controlled cloth guide roller 3 and a lateral installation frame for mounting the first electrically controlled cutting blade 4 and the second electrically controlled cutting blade 5 are fixed on the outer side of the embedded assembly plate 21 .

[0035] In order to cooperate with the material guiding, the electrically controlled cloth guiding roller 3 comprises an inner active roller 31 and an inner driven roller 32 which are installed inside the lateral assembly frame.

[0036] The internal active roller 31 is driven by a motor to transport the nonwoven fabric between the internal active roller 31 and the internal driven roller 32 .

[0037] In order to cooperate with lateral flip adjustment and cutting, the first electrically-controlled cutting blade 4 and the second electrically-controlled cutting blade 5 include a flip assembly frame 451 movably assembled with the inner side of the lateral mounting frame, a replaceable blade 452 fixed inside the flip assembly frame 451, and an adjustment support rod 453 movably mounted on the inner side of the lateral mounting frame.

[0038] The extended end of the adjusting strut 453 is movably assembled with the flip assembly frame 451 through the connecting shaft, and the replaceable blade 452 is fixedly assembled with the sunken mounting groove on the outer side of the flip assembly frame 451 through the lateral bolts. The adjusting struts 453 on both sides are flipped, so as to perform cutting operation in the manner of scissors.

[0039] In order to circulate the internal heat transfer fluid, the internal circulation heating module 7 includes a fixed air guide cover 71 fixedly installed inside the main frame 1, an electrically controlled centrifugal pump 72 movably installed inside the fixed air guide cover 71, and an arc-shaped electric heating frame 73 installed on the inner arc surface of the fixed air guide cover 71.

[0040] The electrically controlled centrifugal pump 72 rotates at high speed to draw the heat transfer liquid into the fixed guide cover 71 through the internal guide hole 9, and then heats the heat transfer liquid whose temperature has not reached the set temperature in the arc-shaped electric heating frame 73 inside the fixed guide cover 71, and then introduces it back to the internal guide hole 9 from the inside of the fixed guide cover 71, introduces it into the embedded assembly disk 21 through the internal guide hole 9, introduces it into the lateral assembly frame through the embedded assembly disk 21, and introduces it into the electrically controlled cloth guide roller 3 through the lateral assembly frame, and heats and cures the non-woven fabric through the electrically controlled cloth guide roller 3, and then the electrically controlled cloth guide roller 3 guides it back to the lateral assembly frame through the other end, and uses the lateral assembly frame to reflux to the embedded assembly disk 21, and finally guides it back to the internal guide hole 9.

[0041] In order to cooperate with the internal flow diversion, the heat circulation channel 6 includes a first guide channel 61 and a first return channel 62 opened inside the main frame 1, a second guide channel 63 and a second return channel 64 opened inside the lateral assembly frame, a third guide channel 65 and a third return channel 66 opened inside the embedded assembly disk 21, and a fourth guide channel 67 opened inside the electrically controlled cloth guide roller 3.

[0042] In order to perform a transverse straightening operation on the introduced nonwoven fabric, the outer sides of the inner driving roller 31 and the inner driven roller 32 are provided with outwardly protruding oblique tension sleeves 33.

[0043] The inclined tension sleeve 33 is arranged on the outer side of the internal active roller 31 and the internal driven roller 32 of the lead-in section, and is used for horizontal placement before cutting. The internal active roller 31 of the lead-in section keeps rotating slowly during cutting, while the internal active roller 31 of the lead-out section keeps stationary during cutting, so as to ensure that the nonwoven fabric is stretched straight in the longitudinal direction.

[0044] In order not to affect the material guiding and to increase the tensioning area, the inclined tensioning sleeves 33 on the outer sides of the inner active roller 31 and the inner driven roller 32 are staggered.

[0045] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
