Description

Technical Field

[0001] The invention belongs to the technical field of supporting facilities for the production of non-woven products, and in particular relates to a fiber feeding device for the production of non-woven products. Background Art

[0002] The non-woven products mentioned above mainly but not limited to flushable wet toilet paper. This kind of product is usually fed in a two-pronged way in the production process (taking two raw materials as an example, if there are many types of raw materials, it will be fed in multiple ways accordingly). The so-called two-pronged way of feeding means: one is to supply wood pulp raw materials, and in addition to wood pulp raw materials, there are other raw materials such as sugar cane, bamboo fiber, etc.; the second is to provide short-cut fiber raw materials such as lyocell fiber, short-cut viscose fiber, tencel, etc. The weight percentages of the above two materials are usually 65-85% and 15-35% respectively. In the process of producing the above-mentioned flushable wet toilet paper, since the short-cut fibers are mostly loosely packaged, they cannot be transported by conveyor belts. In view of this, the fiber feeding device described in the present invention is for fiber raw materials of loosely packaged short-cut fibers.

[0003] In the process of producing the above-mentioned flushable wet toilet paper, i.e., non-woven products, various raw materials, such as wood pulp fiber raw materials, need to be provided for the subsequent pulping process, and when the physical shape of the wood pulp fiber raw materials is a block, they are transported to the material barrel by a conveyor belt, and when the wood pulp fiber is in the form of a roll, they are delivered to the corresponding workstation by a well-known and commonly used feeding method in the industry. At the same time, the aforementioned loosely packaged short-cut fiber raw materials are transported to the corresponding material barrel. In addition to the aforementioned wood pulp fiber raw materials and short-cut fiber raw materials, other corresponding raw materials can be added as needed.

[0004] As can be seen from the above description, the fiber feeding device is an indispensable auxiliary equipment in the complete set of equipment involved in the production of the aforementioned flushable wet toilet paper product, i.e., wood pulp fiber. At present, the aforementioned chopped fibers are fed into the aforementioned barrel (i.e., "fiber tank") after being weighed in a primitive way, i.e., by carrying on shoulders or by hand. If the chopped fibers are introduced into the aforementioned fiber tank as a barrel by manual weighing and manual feeding, it will undoubtedly be restricted by the lack of human resources, and even if the workers perform manual weighing and manual feeding, on the one hand, the labor intensity of the workers is high, and on the other hand, there is uncertainty in the operation (such as inaccurate weighing) and accompanying danger.

[0005] In the public Chinese patent documents, technical information related to the fiber feeding device can be seen, such as the "a pulp feeding mechanism for paper towel processing" recommended by CN210795039U. By reading paragraphs 0029 to 0045 of the patent specification, it can be known that the servo motor drives the screws with opposite thread directions at both ends to rotate, so that the sliders matched with the screw threads are displaced toward each other or repelled from each other, and the hinge rod is correspondingly driven to prop up or fall (i.e., lift), and the lifting and lowering of the hinge rod drives the floating plate to lift and lower accordingly, and then the oil cylinder arranged on the floating plate pushes the bottom of one end of the feeding box, and the feeding box located above the floating plate is in an inclined state with one end high and the other end low, so as to achieve the purpose of making the wood pulp in the feeding box flow out from the upper edge of the horizontal plate at the low end of the feeding box.

[0006] Since the CN210795039U is designed for liquid wood pulp, it cannot be used for the dry short fiber delivery. Because in actual use, it is usually required that the fibers be completely unloaded from the feed box in one go and in an instant, but the aforementioned patent structure cannot fully unload the wood pulp in the feed box even if the time is long and the unloading is slow (there is always a residual amount); and because the aforementioned patent is aimed at wood pulp that has been made into pulp from fibers, the feed box does not need to be raised to a higher height and the lifting speed does not need to be pursued, because if the lifting speed is too fast, the pulp will overflow from the upper edge of the feed box, and objectively, the speed is also limited because the screw rod is used to support or lower the hinge rod through the moving block; considering the unloading factor, the patent forms a pair of box plates parallel to each other in the length direction of the feed box into a trapezoidal shape, so the loading capacity each time is relatively limited.

[0007] Based on the above-mentioned existing technical conditions, it is necessary to explore a fiber feeding device with a reasonable structure. The technical solution to be introduced below is produced in this context. Summary of the invention

However, the description of the embodiments is not a limitation of the present invention. Any equivalent changes made based on the concept of the present invention that are merely formal and not substantial should be regarded as within the scope of the technical solution of the present invention.

[0022] In the following description, all concepts related to up, down, left, right, front and back directions or orientations are based on the current Figure 1 The position is taken as a reference, and thus it cannot be understood as a special limitation on the technical solution provided by the present invention.

[0023] See also Figure 1 and Figure 2, showing a frame 1 with a hollow frame structure in which the bottom is supported on the ground and the upper part stretches upward (i.e., extends upward) in the use state; showing a hopper mechanism 2 (also called "feeding mechanism" or "fiber feeding mechanism", the same below) and a hopper traction and lifting mechanism 3, the hopper mechanism 2 is arranged on the aforementioned frame 1 and forms a rolling pair cooperation relationship with the aforementioned frame 1 for upward and downward movement, the hopper traction and lifting mechanism 3 is arranged on the aforementioned frame 1 and connected to the hopper mechanism 2; showing a hopper frame traction belt driving mechanism 4, the hopper frame traction belt driving mechanism 4 is arranged on the top of the aforementioned frame 1 and is drivingly connected to the aforementioned hopper traction and lifting mechanism 3.

[0024] Please see the key Figure 1 And combined with Figure 2 The aforementioned rack 1 includes a rack front left column 11, a rack front right column 12, a rack rear left column 13 and a rack rear right column 14. The lower ends of the rack front left and right columns 11, 12, the rack rear left column 13 and the rack rear right column 14 are connected by a rack bottom frame 15. That is to say, the lower ends of the aforementioned rack front left and right columns 11, 12, and the rack rear left and right columns 13, 14 are controlled by the rack bottom frame 15 to form a whole. In order to avoid the lower ends of the left and right front columns 11, 12 and the left and right rear columns 13, 14 of the frame from falling apart, the locomotive frame 1 can be reliably fixed to the embedded parts on the floor of the use place (through fasteners such as bolts or similar components) through one (a total of four) frame column bottom fixing plates 18 located at the left and right front columns 11, 12 and the left and right rear columns 13, 14 of the frame, and the upper ends, i.e., the left and right front columns 11, 12, The upper ends of the left and right rear columns 13, 14 of the frame are connected by the frame top frame 16, and the area enclosed by the left and right front columns 11, 12 of the frame, the left and right rear columns 13, 14 of the frame, the frame bottom frame 15 and the frame top frame 16 constitutes a bucket up and down lifting space 17 (also known as a "bucket up and down lifting channel").

In addition, the rear of the frame top frame 16 extends backward, so a frame top frame support arm 161 (the industry usually calls this structural member "diagonal brace") is used on the left and right sides of the rear of the frame to be fixed to the frame rear left and right columns 13, 14 respectively, so as to reflect the stability effect of the triangle (specifically, it can be seen that the frame top frame 16 has a certain degree of backward extension, and the frame top frame support arm 161 is used on the left and right sides of the rear of the frame (the industry usually calls this structural member "diagonal brace") to reflect the stability effect of the triangle (specifically, it can be seen that the frame top frame 16 has a certain degree of backward extension, and the frame top frame support arm 161 is used on the left and right sides of the rear of the frame to fix to the frame rear left and right columns 13, 14 respectively, so as ...

However, in order to facilitate the feeding of the hopper body 21 of the structural system of the hopper mechanism 2 to be described in detail below, an opening is formed between the left and right rear columns 13 and 14 to avoid interference in the operation of feeding fibers to the hopper body 21.

[0027] In a broad sense, the structure of the frame 1 in the present invention is in the shape of a cross frame.

[0041] See also Figure 4 and Figure 5 , the applicant combined Figures 1 to 3 Describe the working process of the present invention: Figure 4The initial state shown is that the hopper body support frame 22 together with the hopper body 21 fixed thereto are supported on the frame bottom frame 15, and the hopper body 21 is in a state of receiving (accepting) the chopped fibers used to make the aforementioned raw materials for flushable wet toilet paper.

Then, the online operator continues to press the corresponding button on the electrical control switch 131, and the aforementioned hook lifting motor 55 works in the reverse direction relative to the aforementioned and lifts the fiber package 6 upward to the position where it is lifted by the hook 57b. Figure 4 At this time, the online operator continues to operate the corresponding button on the electrical control switch to make the mobile motor 51 work and drive the mobile reduction box 52 to work, and the mobile motor shaft 511 drives the active roller 53a, and at the same time, the mobile reduction box final power output shaft 521 drives the driven roller 53b, and the active and driven rollers 53a and 53b synchronously move along the lower edge 1621 of the left side of the I-beam from right to left (with Figure 4 and Figure 5 The fiber bag 6 is moved to the upper open part of the bucket cavity 211 corresponding to the hopper body 21 (as shown in the position state). During the above process, the first and second follower rollers 53e and 53f also move along the lower edge 1622 of the right side of the I-beam. Then, the online operator cuts or cuts the bottom of the fiber bag 6 with a relatively sharp tool such as scissors or similar parts to discharge the fibers in the fiber bag 6 into the bucket cavity 211. Then, the above process is reversed to move the entire fiber bag 6 lifting and lifting mechanism 5 to the right and present a Figure 4 The state shown by the solid line is the state of entering the lifting state of the fiber package 6 and being weighed by the weighing sensor 581, and this is repeated. The chopped fibers of the fiber package 6 are chopped viscose fibers, lyocell fibers or tencel fibers, etc.

[0042] After the hopper body 21 receives the material, the online operator still operates the corresponding button on the aforementioned electrical control switch 131, and the belt traction drive shaft driving motor 41 of the hopper frame traction belt drive mechanism 4 works and drives the belt traction drive wheel shaft to drive the reduction box 42, and the belt traction drive wheel shaft drives the reduction box 42, and the reduction box final power output shaft 421 drives the reduction box power output active pulley 43, and the reduction box power output active pulley 43 drives the reduction box power output shaft driven pulley 44 through the driving belt 45, and the reduction box power output shaft driven pulley 44 drives the hopper traction lifting mechanism 3. The belt traction drive shaft 31 of the structural system drives the left traction pulley 313 and the right traction pulley 314 by the rotation of the belt traction drive shaft 31 at the same time, and the left and right traction pulleys 313, 314 synchronously drive the left and right traction belts 34, 35 respectively, so that the left connecting block 32 of the traction belt and the right connecting block 33 of the traction belt are synchronously displaced upward. In this process, the left roller 2431 of the left roller shaft of the connecting beam on the back frame and the left roller 2531 of the left roller shaft of the connecting beam under the back frame roll upward along the additional column longitudinal raceway 1111 of the left front column of the frame and the longitudinal raceway 112 of the left front column of the frame respectively. At the same time, the right roller 2441 of the right roller shaft of the connecting beam on the back frame and the right roller 2541 of the right roller shaft of the connecting beam under the back frame respectively roll upward along the longitudinal roller track 1211 of the additional column in front of the right upright of the frame and the longitudinal roller track 122 of the right upright in front of the frame. When the left roller 2431 of the left roller shaft of the connecting beam on the back frame and the right roller 2441 of the right roller shaft of the connecting beam on the back frame respectively reach the groove of the first and second bent parts 113 and 123 in front of the additional column, the mouth of the bucket cavity 211 of the hopper body 21, that is, the cavity mouth of the hopper body 21, is formed by Figure 5 In the inverted state shown, the opening of the hopper body 21 is turned downward, so that the fibers in the hopper cavity 211 are poured into the bucket 7 connected to the aforementioned bucket connecting arm 19e. Figure 5 The state shown is that the left connecting block 32 of the traction belt touches the upward limit position signal collector 115 of the hopper and is blocked by the upward limit position stop block 114 of the hopper at the same time, so the upward limit position signal collector 115 of the hopper feeds back the signal to the electrical controller, and the electrical controller causes the aforementioned belt drive wheel shaft drive motor 41 to work in the reverse direction, and until the hopper body 21 returns to Figure 4 As shown, the operation is repeated in this way so that the fibers are supplied to the barrel 7 as needed, so as to be quantitatively supplied to the subsequent pulping process.
