Description

Technical Field

[0001] The utility model belongs to the technical field of non-woven fabric finishing equipment, and in particular relates to a non-woven fabric slitting and double-station winding device. Background Art

[0002] As is known in the industry, according to the different application occasions or application purposes of non-woven fabrics, it is usually necessary to use post-finishing equipment at the subsequent workstation to cut the non-woven fabric that has completed the previous process such as the needle punching process in the length direction, that is, in the width direction. For example, a non-woven fabric with a width of 1.8 meters is cut into 0.6 meters, and it is wound up by a winding roller while cutting. Specifically, three units of non-woven fabrics of 0.6 meters each are wound on the same winding roller (the winding roller is also called a "winding roller"). The winding method of collecting three non-woven fabric rolls on the same winding roller at the same time has the following technical problems: not only is it easy to produce biting edges or pressing edges between adjacent finished non-woven fabric rolls, but the roll changing time is long and the roll changing is very troublesome (it is not easy to remove the three cloth rolls from the same winding roller), which affects production efficiency.

[0003] The aforementioned double-station winding device is the aforementioned finishing equipment category. In addition, from the definition of the double-station winding mentioned above, it can be known that it is to roll up the non-woven fabrics cut into the width required by the process at different stations, that is, at different positions without interfering with each other, so as to avoid the aforementioned technical problems, but it needs to be guaranteed by technical measures with reasonable design, reliable operation and relatively simple structure. In the public Chinese patent documents, technical information related to non-woven fabric slitting and winding devices can be seen, such as CN112093555B (a slitting and winding machine) and CN216585878U (a new type of non-woven fabric processing roll cutting machine) and CN214692405U (a non-woven fabric automatic slitting and winding machine), etc. The aforementioned patents, which are not limited to the examples, do not provide any method that helps to make up for the technical problems mentioned by the applicant above.

[0047] In this embodiment, the aforementioned linkage plate forward and backward displacement actuating cylinder 61, the upper winding roller shaft head cover guard cylinder 66 and the lower winding roller shaft head cover guard cylinder 67 are cylinders; when the aforementioned upper winding roller right end support arm 62 and the lower winding roller right end support arm 63 are in a state of backward displacement corresponding to the aforementioned linkage plate yielding cavity 221, the aforementioned upper winding roller shaft head cover 2011 and the lower winding roller shaft head cover 3011 are respectively supported on the aforementioned upper winding roller shaft head The sleeve supporting cavity 621 and the lower winding roller shaft head sleeve supporting cavity 631 are respectively provided with the upper winding roller shaft head sleeve protecting cylinder column 661 and the lower winding roller shaft head sleeve protecting cylinder column 671 extending downwardly out of the cylinder body to protect the upper winding roller shaft head sleeve 2011 and the lower winding roller shaft head sleeve 3011 at positions corresponding to the rear of the upper winding roller shaft head sleeve 2011 and the lower winding roller shaft head sleeve 3011. When the upper winding roller shaft head sleeve protecting cylinder column 661 and the lower winding roller shaft head sleeve protecting cylinder column 671 extend downwardly out of the cylinder body, the upper winding roller shaft head sleeve 2011 and the lower winding roller shaft head sleeve 3011 are protected.

The aforementioned cut cloth roll transfer mechanism 9 is simultaneously docked with the aforementioned upper winding roller shaft head 201 and the lower winding roller shaft head 301, and the cut upper winding roller non-woven fabric roll 40a on the aforementioned upper winding roller 20 and the cut lower winding roller non-woven fabric roll 40b on the aforementioned lower winding roller 30 are transitioned (i.e., transferred) to the aforementioned cut cloth roll transfer mechanism 9. The figure also shows that the aforementioned right box body 2 is equipped with a right box body cavity guard door 24 for shielding the right box body cavity 21.

[0048] From the above description, it can be determined that the action of the linkage plate 68 together with the rear ends of the upper and lower winding roller right end support arms 62 and 63 being displaced backward to the outside of the right box cavity 21 or being displaced forward and returning to the right box cavity 21 at the position corresponding to the aforementioned linkage plate yield cavity 221 is determined by the displacement direction, i.e. the working state, of the linkage plate forward and backward displacement actuating cylinder column 611 of the linkage plate forward and backward displacement actuating cylinder 61.

[0049] See you next time Figure 6 And combined with Figure 1The aforementioned cut cloth roll transfer mechanism 9 includes a longitudinal column 91, an upper cut cloth roll transfer receiving roller 92, a lower cut cloth roll transfer receiving roller 93 and a vertical shaft 94. The longitudinal column 91 corresponds to the right side of the aforementioned right box body 2 and is fixed to the floor of the use place through a longitudinal column fixing plate 911 formed at its bottom in a state where the length of the upper cut cloth roll transfer receiving roller 92 or the length of the lower cut cloth roll transfer receiving roller 93 (the lengths of the upper and lower cut cloth roll transfer rollers 92, 93 are equal to each other) is maintained between the longitudinal column 91 and the right box body 2, but it can also be fixed on a separately equipped bracket. The vertical shaft 94 is arranged on the left side of the longitudinal column 91 in a longitudinal state. The right end of the upper cut cloth roll transfer receiving roller 92 is rotatably hinged to the upper end of the vertical shaft 94 through the upper cut cloth roll transfer receiving roller pivot seat 921, and the left end of the upper cut cloth roll transfer receiving roller 92 is constituted as a free end and is at the center of the left end face of the upper cut cloth roll transfer receiving roller 92. An upper cut cloth roll transfer and receiving roller shaft head 922 is extended at the position, and an upper sliding joint 922 is provided on the upper cut cloth roll transfer and receiving roller shaft head 922, and the right end of the lower cut cloth roll transfer and receiving roller 93 is rotatably hinged to the lower end of the vertical shaft 94 through the lower cut cloth roll transfer and receiving roller pivot seat 931, and the left end of the lower cut cloth roll transfer and receiving roller 93 is constituted as a free end and a lower cut cloth roll transfer and receiving roller shaft head 932 is extended at the center position of the left end face of the lower cut cloth roll transfer and receiving roller 93, and a lower sliding joint 9321 is provided on the lower cut cloth roll transfer and receiving roller shaft head 932, wherein the horizontal heights of the upper and lower cut cloth roll transfer and receiving rollers 92, 93 are respectively consistent with the horizontal heights of the upper and lower winding rollers 20, 30, and the upper and lower sliding joints 9221, 9321 respectively cooperate or release with the right ends of the upper and lower winding roller shaft heads 201, 301.

[0050] See also Figure 7 and Figure 8 And combined with Figures 1 to 6 ,Depend on Figure 7As shown, the nonwoven fabric 40c to be cut is sequentially passed through the nonwoven fabric introduction roller 41, between the nonwoven fabric traction roller 42 and the nonwoven fabric traction roller 43, the nonwoven fabric traction guide roller 44, the nonwoven fabric slitting introduction roller 45a and the upper surface of the bottom knife roller sleeve 37. Since the nonwoven fabric to be cut is cut by the four bottom knives 38 and the four disc blades 36 on the bottom knife roller sleeve 37 during the process of passing through the bottom knife roller sleeve 37, that is, the nonwoven fabric 40c is divided into three in the width direction and cut to form three narrow nonwoven fabrics of the same width. For example, the previous width (width) of the nonwoven fabric 40c is 1.8 meters. After cutting, It becomes three pieces of 0.6-meter-wide narrow non-woven fabrics. The three pieces (i.e., three pieces) of 0.6-meter-wide narrow non-woven fabrics are divided into the following two paths after passing through the non-woven fabric slitting lead-out roller 45b and the slitting non-woven fabric transition guide roller 46a. One path is one (i.e., one piece) of narrow non-woven fabric and passes through the slitting non-woven fabric first upper lead-out roller 46b and the slitting non-woven fabric second upper lead-out roller 46c in sequence and arrives at the aforementioned upper winding roller 20. Under the operation of the aforementioned upper winding roller driving mechanism 5, the upper winding roller 20 is wound or wound into an upper winding roller non-woven fabric roll 40a, and the upper winding roller non-woven fabric roll 40a is located in the middle of the length direction of the upper winding roller 20. The other route has two (i.e. two pieces) of narrow non-woven fabrics, which successively pass through the first lower lead-out roller 46d for slitting non-woven fabrics and the second lower lead-out roller 46e for slitting non-woven fabrics and arrive at the aforementioned lower winding roller 30, and are wound or reeled up by the lower winding roller 30 under the operation of the aforementioned lower winding roller driving mechanism 8.

[0051] When the total length of the narrow nonwoven fabric on the upper and lower winding roller nonwoven fabric rolls 40a, 40b reaches the length measured by the aforementioned meter meter 131, that is, the length required by the process and the electrical controller (also referred to as the "electrical controller") receives a signal, the upper and lower winding roller drive mechanisms 5, 8 and the bottom knife roller drive mechanism 7 stop working, and the online check-in personnel use tools to cut ("cut" or "shear") the narrow nonwoven fabric at the end of the upper and lower winding roller nonwoven fabric rolls 40a, 40b.

[0052] Since the process of transferring the upper winding roller non-woven fabric roll 40a on the upper winding roller 20 to the upper cut fabric roll transfer receiving roller 92 of the cut fabric roll transfer mechanism 9 is exactly the same as the process and operation method of transferring the lower winding roller non-woven fabric roll 40b on the lower winding roller 30 to the lower cut fabric roll transfer receiving roller 93, the applicant will only explain the former below.

[0053] First, the upper sliding joint 9221 is moved to the left to the extent that it docks with the right end of the upper winding roller shaft head 201, so that the upper winding roller 20 and the upper cut cloth roll transfer receiving roller 92 form a docking relationship, and then the upper winding roller shaft head cover guard cylinder 66 is operated to make the upper winding roller shaft head cover guard cylinder column 661 move upward, that is, into the cylinder body, and then the linkage plate front and rear displacement actuating cylinder 61 is operated, and the linkage plate front and rear displacement actuating cylinder column 611 drives the linkage plate 68 together with the upper and lower winding roller right end support arms 62, 63 to move forward, that is, to the right box cavity 21. Then, the online check-in staff moves the upper winding roller non-woven fabric roll 40a previously located on the upper winding roller 20 to the right to the upper cut cloth roll transfer receiving roller 92. Then, the upper sliding joint 9221 is returned to the upper cut fabric roll transfer receiving roller shaft head 922, which is integrally located thereon, so as to release the docking relationship with the upper winding roller shaft head 201. Finally, the check-in staff rotates the upper winding roller non-woven fabric roll 40a together with the upper cut fabric roll transfer receiving roller 92 by means of tools or by hand to a sufficient degree that there is no interference with the operation of removing the upper winding roller non-woven fabric roll 40a, so as to remove the upper winding roller non-woven fabric roll 40a from the upper cut fabric roll transfer receiving roller 92 by means of tools such as a lifting device or by manual cooperation (for example, cooperation by two workers). Then, the reverse action process is followed until the upper winding roller shaft head cover 2011 is supported on the upper winding roller shaft head cover supporting cavity 621 and the upper winding roller shaft head cover guard cylinder column 661 moves downward to protect the rear side of the upper winding roller shaft head cover 2011, entering the aforementioned cutting and winding working state, and repeating this process.

[0054] In summary, the technical solution provided by the utility model makes up for the shortcomings of the existing technology, successfully completes the invention task, and faithfully realizes the technical effects stated by the applicant in the technical effect column above.
