Description

Technical Field

[0001] This utility model belongs to the field of fiber equipment, and in particular relates to a feeding device for a high-density, low-dust wiping cloth. Background Technology

[0002] Cleanroom wipes possess strong absorbency, abrasion resistance, softness, acid and alkali resistance, and dust removal capabilities. Because they effectively remove dust, liquids, and oil from surfaces without damaging or scratching them, they are widely used in cleanrooms to remove spills, excess processing chemicals, debris, and dust particles from sensitive devices. Currently, cleanroom wipes are widely used in precision electronics manufacturing, medical, bioengineering, optics, and petrochemical industries.

[0003] After the wiping cloth is made and placed in a roll, it needs to be further cut, folded and shaped to be ready for sale. In this process, the cloth roll is usually lifted and installed in the working position by manual operation of the machine, which reduces production efficiency.

[0004] For example, Chinese patent literature discloses a feeding device for a fabric inspection machine [patent application number: CN202221509989.5], which includes a fabric inspection machine. The upper two ends of the frame of the fabric inspection machine are equipped with baffles to prevent the fabric from falling. The baffles are higher than the rotating rollers of the fabric inspection machine and are symmetrically arranged. The feeding end of the fabric inspection machine is provided with a feeding device, which includes a roller bed and a cylinder. One end of the roller bed is hinged to the frame on both sides of the feeding end of the fabric inspection machine. The plane at the hinge end of the roller bed is not lower than the upper surface of the baffles. The telescopic end of the cylinder is hinged to the bottom surface of the roller bed, and the other end is hinged to the lower side of the frame. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned problems by providing a feeding device for high-density, low-dust wiping cloths.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A feeding device for a high-density, low-dust wiping cloth includes a cloth output frame, a feeding frame rotatably mounted on the cloth output frame, a feeding channel on the feeding frame, a drive mechanism connected to the end of the feeding frame away from the cloth output frame, a transition channel on the cloth output frame that can communicate with the feeding channel, the transition channel being placed at an angle, a cloth output placement hole connected to the end of the transition channel away from the feeding channel, and an anti-backward structure provided at the connection between the transition channel and the cloth output placement hole.

[0008] In the above-mentioned feeding device for high-density, low-dust wiping cloth, baffles are provided on both sides of the feeding frame, the feeding channel is located between the two baffles, and the baffles are provided with cloth roll shaft channels arranged parallel to the feeding channel. The cloth roll shaft channels can communicate with the transition channel.

[0009] In the aforementioned feeding device for high-density, low-dust wiping cloth, the feeding channel is also equipped with several free rollers that are rotatably connected to the feeding frame.

[0010] In the above-mentioned feeding device for high-density, low-dust wiping cloth, the anti-reverse structure includes anti-reverse blocks located on both sides of the transition channel. The anti-reverse blocks are slidably disposed in the slide groove. An elastic element is provided between the anti-reverse block and the inner wall of the slide groove. The elastic element can cause the anti-reverse block to extend into the transition channel.

[0011] In the above-mentioned feeding device for high-density, low-dust wiping cloth, the elastic element is a spring, and the spring is in a compressed state.

[0012] In the above-mentioned feeding device for high-density, low-dust wiping cloth, the portion of the anti-backward block extending into the transition channel is located between the transition channel and the cloth outlet placement hole. This portion has an inclined surface on the side near the transition channel and a curved surface on the other side near the cloth outlet placement hole. The distance between the two inclined surfaces gradually decreases from the transition channel to the cloth outlet placement hole. The inner diameter of the curved surface is the same as the inner diameter of the cloth outlet placement hole.

[0013] In the above-mentioned feeding device for high-density, low-dust wiping cloth, the transition channel includes an adjustment channel and an entry channel. The width of the adjustment channel gradually decreases from the inlet to the outlet, and the inner wall of the adjustment channel is inclined. The width at the outlet of the adjustment channel is the same as the width of the entry channel.

[0014] In the above-mentioned feeding device for high-density, low-dust wiping cloth, the driving structure includes a hydraulic cylinder, the output shaft of which is rotatably connected to the feeding frame, and the hydraulic cylinder is rotatably mounted on the table or frame.

[0015] In the above-mentioned feeding device for high-density, low-dust wiping cloth, the cloth output frame is also connected to a shaft taking block by a detachable structure, the cloth output placement hole is set in the shaft taking block, and the shaft taking block can be detached from the cloth output frame.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. The fabric roll feeding process is achieved by relying on the mechanical structure and the weight of the fabric roll itself, and the anti-backward structure can prevent the fabric roll from moving other than rotating during operation.

[0018] 2. The central axis of the fabric roll is located inside the fabric roll shaft channel to prevent the fabric roll from slipping off the feeding rack during its descent and movement, thus preventing potential hazards.

[0019] 3. The friction between the fabric roll and the feeding channel is reduced by the rotatable free roller to prevent fabric wrinkles and damage on the fabric roll.

[0020] 4. Since the widths of the two ends of the central shaft of the fabric roll are different lengths when entering the corresponding adjustment channels, the inclined inner wall of the adjustment channel can act as a guide, so that both ends of the central shaft of the fabric roll can smoothly enter the corresponding entry channels and finally smoothly enter the fabric placement hole.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] This utility model provides a feeding device for high-density, low-dust wiping cloth, combined with Figure 1-3 As shown, the device includes a fabric feeding frame 10, a feeding frame 11 rotatably mounted on the fabric feeding frame 10, a feeding channel 12 on the feeding frame 11, a drive mechanism connected to the end of the feeding frame 11 away from the fabric feeding frame 10, a transition channel 13 on the fabric feeding frame 10, the transition channel 13 communicating with the feeding channel 12, the transition channel 13 being placed at an angle, a fabric placement hole 14 connected to the end of the transition channel 13 away from the feeding channel 12, and an anti-backward structure 15 at the connection between the transition channel 13 and the fabric placement hole 14.

[0027] In this embodiment, when feeding the fabric roll, the fabric roll is placed on the feeding channel 12 on the feeding frame 11. Then, the drive structure causes the feeding frame 11 to rotate upward, so that the feeding channel 12 gradually tilts downward and connects with the transition channel 13. Under its own weight, the fabric roll passes through the feeding channel 12 and the transition channel 13 in sequence and enters the fabric outlet placement hole 14, that is, the fabric roll enters the working rotatable position. The feeding process of the fabric roll is realized by the mechanical structure and the weight of the fabric roll itself. The anti-backward movement structure 15 can prevent the fabric roll from moving other than rotating during operation.

[0028] The feeding rack 11 has baffles 16 on both sides, the feeding channel 12 is located between the two baffles 16, and the baffles 16 have cloth roll shaft channels 17 arranged parallel to the feeding channel 12. The cloth roll shaft channels 17 can communicate with the transition channel 13.

[0029] In this embodiment, the central axis of the fabric roll is located inside the fabric roll shaft channel 17 to prevent the fabric roll from slipping out of the feed rack 11 during its descent and movement, thus preventing potential dangers.

[0030] The feeding channel 12 is also provided with several free rollers 18 that are rotatably connected to the feeding frame 11.

[0031] In this embodiment, the friction between the fabric roll and the feeding channel 12 is reduced by the rotatable free roller 18 to prevent damage such as fabric wrinkles on the fabric roll.

[0032] The anti-return structure 15 includes anti-return blocks 19 located on both sides of the transition channel 13. The anti-return blocks 19 are slidably disposed in the slide groove 20. An elastic element is provided between the anti-return blocks 19 and the inner wall of the slide groove 20. The elastic element can cause the anti-return blocks 19 to extend into the transition channel 13.

[0033] The elastic element is spring 21, and spring 21 is in a compressed state.

[0034] The portion of the anti-reverse block 19 extending into the transition channel 13 is located between the transition channel 13 and the fabric placement hole 14. This portion has an inclined surface 22 on the side near the transition channel 13 and a curved surface 23 on the other side near the fabric placement hole 14. The distance between the two inclined surfaces 22 gradually decreases from the transition channel 13 to the fabric placement hole 14. The inner diameter of the curved surface 23 is the same as the inner diameter of the fabric placement hole 14.

[0035] In this embodiment, during the descent of the fabric roll, its own weight and the resulting kinetic energy allow it to push aside the inclined surface 22 and overcome the elastic force of the spring 21, enabling the central axis of the fabric roll to smoothly enter the fabric placement hole 14. Since the anti-reverse block 19 is located above the central axis of the fabric roll during operation, the fabric roll does not have the adjustment to push aside the anti-reverse block 19. Furthermore, the curved surface 23 completes the inner wall of the fabric placement hole 14 to make it as round as possible, so that it will not bump or vibrate when the central axis of the fabric roll rotates.

[0036] The transition channel 13 includes a positioning channel 24 and an entry channel 25. The width of the positioning channel 24 gradually decreases from the inlet to the outlet, and the inner wall of the positioning channel 24 is inclined. The width of the outlet of the positioning channel 24 is the same as the width of the entry channel 25.

[0037] In this embodiment, when the central shaft of the fabric roll enters the transition channel 13, the central shaft of the fabric roll will first enter the adjustment channel 24. Since the widths of the two ends of the central shaft of the fabric roll entering the corresponding adjustment channels 24 are different lengths, the inclined inner wall of the adjustment channel 24 can play a guiding role, so that both ends of the central shaft of the fabric roll can smoothly enter the corresponding entry channel 25 and finally smoothly enter the fabric placement hole 14.

[0038] The drive structure includes a hydraulic cylinder 26, the output shaft of which is rotatably connected to the loading rack 11, and the hydraulic cylinder 26 is rotatably mounted on the table or frame.

[0039] The fabric feeding frame 10 is also connected to a shaft taking block 27 via a detachable structure. The fabric feeding placement hole 14 is located inside the shaft taking block 27, and the shaft taking block 27 can be detached from the fabric feeding frame 10.

[0040] In this embodiment, after the fabric roll has finished discharging, the central shaft of the fabric roll can be removed by disassembling the shaft removal block 27. The shaft removal block 27 can be removed by fixing with pins or bolts.

[0041] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0042] Although this article uses terms such as fabric feeder 10, feeder 11, feed channel 12, transition channel 13, fabric feed placement hole 14, anti-backward structure 15, baffle 16, fabric roll shaft channel 17, free roller 18, anti-backward block 19, chute 20, spring 21, inclined surface 22, curved surface 23, adjustment channel 24, entry channel 25, hydraulic cylinder 26, shaft taking block 27, etc., these terms are used only for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would be contrary to the spirit of this utility model.
