DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] Embodiment 1: A scouring pad production device, such as Figure 1-Figure 7 As shown, it comprises a frame 1, the inner side of the frame 1 is provided with a conveying mechanism 3 for conveying the scouring pad, and the inner side of the end of the frame 1 is provided with a cutting mechanism 2 for cutting the scouring pad.

[0026] The cutting mechanism 2 includes a cutter 4 and a cutter groove frame 9, the cutter 4 and the cutter groove frame 9 cooperate with each other, the outer walls of the cutter 4 and the cutter frame 5 on the opposite sides are fixed with the cutter frame 5 by fixing bolts 6, both ends of the cutter frame 5 are rotatably connected to limit rollers 7, the inner wall of the frame 1 is provided with a guide groove 8, and the limit roller 7 rolls and cooperates with the inner wall of the guide groove 8.

[0027] The path of the guide groove 8 is a broken line, and the guide grooves 8 near the two ends are arranged in a straight line, and the guide grooves 8 near the middle are arranged obliquely.

[0028] When the device is in use, the scouring pad can be conveyed through the conveying mechanism 3. After the positions of the conveying cutter 4 and the knife groove frame 9 are reached, the cutter 4 and the knife groove frame 9 will simultaneously and synchronously move toward the middle of the scouring pad and cut by extrusion and shearing. At the same time, when the cutter 4 and the knife groove frame 9 move toward each other and are about to contact the scouring pad for cutting, the limiting roller 7 will cooperate with the inclined part of the guide groove 8, so that the cutter 4 and the knife groove frame 9 have lateral movement in addition to longitudinal movement.

[0029] The device cuts by setting a cutter 4 and a knife groove frame 9. The cutter 4 and the knife groove frame 9 are guided by the cooperation of the limit roller 7 and the guide groove 8. Therefore, when the cutter 4 and the knife groove frame 9 cut the scouring pad, the cutter 4 and the knife groove frame 9 also have a lateral branch movement. The lateral branch movement is used to balance the conveying speed, so that the cutter 4, the knife groove frame 9 and the scouring pad do not have a relative movement in the lateral direction. Therefore, when cutting, there is no need to stop conveying, and the whole process is carried out continuously, which increases the cutting efficiency.

[0030] To solve the synchronization problem; Figure 3 As shown, the outer side of the limiting roller 7 is rotatably connected to the outer frame 10, the outer wall of the outer frame 10 is rotatably connected to the connecting rod 12 through a hinge rod 11, the other ends of the two connecting rods 12 are rotatably connected to the same slide 18, the inner wall of the slide 18 is slidably connected to the slide rail 19, and the slide rail 19 is fixed to the outer wall of the frame 1 by bolts.

[0031] The side wall of the frame 1 is rotatably connected to a turntable 15 , and the outer wall of the turntable 15 is rotatably connected to a second connecting rod 17 via a second hinge shaft 16 , and the other end of the second connecting rod 17 is rotatably connected to the outer wall of the slide 18 .

[0032] The outer wall of the turntable 15 is provided with teeth 14 , and the outer wall of the teeth 14 is meshed with a gear 13 , and the gear 13 is transmission-coordinated with the conveying mechanism 3 .

[0033] When the conveying mechanism 3 is conveying, it can drive the gear 13 to rotate, thereby driving the turntable 15 to rotate through the teeth 14. When the turntable 15 rotates, it can drive the slide 18 to move back and forth through the connecting rod 2 17, thereby driving the cutter 4 and the knife groove frame 9 to move up and down through the connecting rod 12 to perform cutting.

[0034] This device utilizes the slide 18 for transition, and then combines the connection between the gear 13 and the conveying mechanism 3, so that the conveying movement and the cutting movement can be integrated. On the one hand, it can save power source layout, and on the other hand, it can also link the conveying and cutting to ensure the consistency of the cutting length, while also simplifying the control logic.

[0035] In order to solve the transportation problem; Figure 4 , 5As shown, the conveying mechanism 3 is composed of two groups of conveying rollers 21 arranged up and down, and the conveying rollers 21 are rotatably connected to the inner side of the frame 1 through roller shafts 20.

[0036] One of the rollers 20 located at the top and one of the rollers 20 located at the bottom are mutually driven and matched through gear 2 2, and the rollers 20 located in the same group are driven and matched through a synchronous transmission component 24. In this embodiment, the specific type of the synchronous transmission component 24 is not limited, and it can be a belt drive or a chain drive, which is intended to ensure that the rollers 20 in the same group rotate synchronously, at the same speed, and in the same direction. Since the load on the scouring pad is relatively small, the preferred synchronous transmission component 24 in this embodiment is a belt drive mechanism, and every two adjacent rollers 20 are driven by a synchronous belt.

[0037] A motor 23 is fixed to the side wall of the frame 1 by bolts, and the output shaft of the motor 23 is fixedly connected to one of the roller shafts 20 by a coupling.

[0038] When the motor 23 is started, it can drive the roller shaft 20 to rotate, thereby driving all the conveying rollers 21 to rotate at the same speed through the synchronous transmission component 24 and the gear 2 22, and the upper conveying roller 21 and the lower conveying roller 21 rotate in opposite directions. At this time, the scouring pad is placed between the two groups of conveying rollers 21 for conveying.

[0039] In order to solve the limitation problem; Figure 6 , 7 As shown, the conveying roller 21 includes a roller body 25 fixedly connected to the roller shaft 20 and a limiting ring 27 movably sleeved on the outer wall of the roller body 25 .

[0040] The outer wall of the roller body 25 is provided with a limiting groove 30, and the inner wall of the limiting ring 27 is fixed with a limiting block 29, and the limiting block 29 is movably limited and matched with the inner wall of the limiting groove 30, and the inner wall of the limiting ring 27 is connected with a countersunk bolt 28 through a thread, and the end face of the countersunk bolt 28 contacts and matches with the inner wall of the limiting groove 30.

[0041] The outer wall of the roller body 25 is provided with uniform anti-slip grooves 26 .

[0042] Since the scouring pad will be cut obliquely if its length is not perpendicular to the cutting direction during transportation, making the slices irregular, when the device is used, the countersunk bolt 28 can be loosened according to the length of the scouring pad, and one or two limiting rings 27 can be moved so that the two limiting rings 27 are attached to the two sides of the scouring pad, and then the countersunk bolt 28 can be tightened.

[0043] This device, by setting a limiting ring 27, can limit the two sides of the scouring pad, so as to ensure that during transportation, the conveying direction is parallel to the length direction of the scouring pad, and the conveying direction and the length direction are both perpendicular to the cutting surface, thereby avoiding oblique cutting and increasing the regularity of the slices.

[0044] When the present embodiment is in use, the scouring pad can be conveyed through the conveying mechanism 3. After the conveying cutter 4 and the knife groove frame 9 are positioned, the cutter 4 and the knife groove frame 9 will simultaneously and synchronously move toward the middle of the scouring pad and cut by extrusion and shearing. At the same time, when the cutter 4 and the knife groove frame 9 move toward each other and are about to contact the scouring pad for cutting, the limiting roller 7 will cooperate with the inclined part of the guide groove 8, so that the cutter 4 and the knife groove frame 9 have lateral movement in addition to longitudinal movement. When the conveying mechanism 3 is conveying, it can drive the gear 13 to rotate, thereby driving the turntable 15 to rotate through the teeth 14. When the turntable 15 rotates, it can drive the slide 18 to reciprocate through the connecting rod 2 17, thereby driving the slide 18 to reciprocate through the connecting rod 12 The cutter 4 and the knife groove frame 9 reciprocate up and down to perform cutting. When the motor 23 is started, it can drive the roller shaft 20 to rotate, thereby driving all the conveying rollers 21 to rotate at the same speed through the synchronous transmission component 24 and the gear 2 22, and the upper conveying roller 21 and the lower conveying roller 21 turn in opposite directions. At this time, the scouring pad is placed between the two groups of conveying rollers 21 for conveying. When the scouring pad is being conveyed, if the length direction of the scouring pad is not perpendicular to the cutting direction, it will cause oblique cutting, making the slices irregular. When the device is used, the countersunk bolt 28 can be loosened according to the length of the scouring pad, and one or two limit rings 27 can be moved so that the two limit rings 27 are attached to the two sides of the scouring pad, and then the countersunk bolt 28 can be tightened.

[0045] Embodiment 2: A scouring pad production process comprises the following steps: S1: Raw material preparation, preparation of fiber materials, abrasives and adhesives; S2: Pretreatment molding, mixing and pretreatment: different types of fibers are mixed and pretreated to remove impurities in the raw materials, and then opened and subsequently molded by knitting, weaving or non-woven molding; S3: soaking the fiber web in a mixture containing an abrasive and an adhesive, and then drying the soaked fiber web to solidify the adhesive; S4: cutting, cutting the cured scouring pad; S5: Packaging: Packaging the cut scouring pads.

[0046] In the step S4, the scouring pad production equipment in Example 1 is used for cutting.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
