Description

Technical Field

[0001] The present application relates to the technical field of fabric sanding, and in particular to a sanding device for fabric production. Background Art

[0002] The sanding treatment of textile fabrics is a functional processing. The fabric is rubbed by a sanding machine and emery leather to form a short fluff layer on the surface of the fabric. It not only retains the original characteristics but also gives the fabric a new style, increasing warmth and softness. It is suitable for winter warmth products and products used close to the body.

[0003] Existing sanding equipment generally includes a conveying roller group for conveying fabrics and a sanding roller for generating friction with the fabric surface. The sanding roller generates relative motion with the fabric during rotation, thereby generating friction, and a short nap layer is generated on the fabric surface through the friction process. However, with the long-term use of the sanding roller, static electricity will be generated on the surface of the sanding roller, which will then adsorb or adhere to the wool material. The wool material adhering to the surface of the sanding roller will easily lead to a poor sanding effect of the sanding roller on the subsequent fabric, so it needs to be improved. Summary of the invention

[0004] In order to reduce the attachment of wool to the surface of the sanding roller and ensure the sanding effect of the sanding roller on the fabric, the present application provides a sanding device for fabric production.

[0005] The present application provides a sanding device for fabric production, which adopts the following technical solution: A sanding device for fabric production comprises a frame, a sanding roller rotatably connected to the frame, and a conveying roller group arranged on the frame for conveying the fabric. The frame is also provided with a scraper and a hair-sticking roller. The scraper and the hair-sticking roller both abut against the surface of the sanding roller, and the scraper and the hair-sticking roller are arranged in sequence along the rotation direction of the sanding roller. The surface of the hair-sticking roller is provided with an adhesive layer for adhering the wool material.

[0006] By adopting the above technical scheme, since the scraper and the hair-sticking roller both contact the surface of the sanding roller, when the sanding roller rotates, the scraper can first scrape the surface of the sanding roller to allow most of the hair to be separated from the sanding roller. Then, as the sanding roller rotates, the hair-sticking roller can be used to adhere to the residual hair on the surface of the sanding roller. Finally, the scraper and the hair-sticking roller cooperate to reduce the amount of hair attached to the surface of the sanding roller, thereby optimizing the sanding effect of the sanding roller on subsequent fabrics.

[0007] Preferably, a surrounding plate is arranged outside the scraper, and the scraper and the surrounding plate together enclose an adsorption chamber, the opening of the adsorption chamber faces the surface of the grinding roller, and an adsorption member is arranged in the adsorption chamber, and the adsorption member is used to form a negative pressure at the opening of the adsorption chamber.

[0008] By adopting the above-mentioned technical scheme, the adsorption chamber formed by the enclosure and the scraper can be used to collect the hair material scraped off by the scraper, and the adsorption component can be used to accelerate the adsorption of the aforementioned fallen hair material into the adsorption chamber, thereby reducing the accumulation of hair material at the end of the scraper, thereby affecting the scraping effect of the scraper on the grinding roller; in addition, since the open position of the adsorption chamber faces the surface of the grinding roller, the adsorption component can also be used to absorb the hair material on the surface of the grinding roller by adsorption, thereby further reducing the amount of hair material attached to the surface of the grinding roller.

[0009] Preferably, a flap is rotatably connected in the adsorption chamber, as well as a rotating part for driving the flap to rotate. An adhesive plate is provided at one end of the adsorption chamber away from the opening of the adsorption chamber. The flap can be attached to the surface of the scraper, and the flap can be rotated to a position attached to the surface of the adhesive plate.

[0010] By adopting the above technical solution, when the flap is not rotating, it is attached to the surface of the scraper to receive the wool material scraped off by the scraper. Then, the scraper can be driven to rotate toward the adhesive plate and attached to the surface of the adhesive plate through the rotating part at regular intervals, so that the wool material collected in the adsorption chamber is concentrated and adhered to the adhesive plate, reducing the situation where the wool material flies around due to the action of the adsorption part, and achieving the sedimentation of the wool material.

[0011] Preferably, the adsorption component includes a fan and a filter, the fan air inlet is connected to the adsorption chamber, the filter is arranged at the fan air inlet, and the filter is located on the rotation path of the flap, so that the flap end wall can contact the filter surface during the rotation of the flap.

[0012] By adopting the above technical solution, the flap can scrape the surface of the filter screen during rotation, thereby reducing the clogging of the filter screen surface and optimizing the adsorption effect of the adsorption component.

[0013] Preferably, the air outlet of the fan faces the contact position between the grinding roller and the scraper.

[0014] By adopting the above technical scheme, the air adsorbed by the fan from the adsorption chamber will be concentratedly output to the contact position between the sanding roller and the scraper through the air outlet of the fan. On the one hand, it can dissipate the heat at the contact position between the sanding roller and the scraper, and on the other hand, it can utilize the effect of wind force to make the hair material on the surface of the scraper and the sanding roller fall off, thereby reducing the amount of adhesion.

[0015] Preferably, the rotating part includes a rotating rod, a gear, a rack, a reset torsion spring and a cam, the cam is arranged at the end of the sanding roller, the rack is slidably connected to the frame, the gear is sleeved on the rotating rod and meshed with the rack, the rotating rod is rotatably connected in the adsorption chamber and is connected to the flap, the reset torsion spring is sleeved on the rotating rod and connected between the rotating rod and the flap, and when the reset torsion spring is not deformed, the flap is attached to the surface of the scraper, and at this time the end of the rack is located on the rotation path of the cam when the cam rotates with the sanding roller.

[0016] By adopting the above technical solution, during the rotation of the sanding roller, the cam rotates with the sanding roller and pushes the rack in the process, so that the rack drives the gear and the rotating rod to rotate, and then the flap rotates toward the bonding plate as the rotating rod rotates, until it is in contact with the bonding plate, the cam rotates and releases the contact with the rack, at which time the rotating rod drives the flap to reverse and reset under the elastic force of the reset torsion spring.

[0017] Preferably, a baffle is further provided in the adsorption chamber, and the baffle is used to open and close the open position of the adsorption chamber.

[0018] By adopting the above technical solution, when the flap rotates in the direction away from the scraper, in order to reduce the wool entering the gap between the flap and the scraper during the rotation of the flap, a baffle is specially provided to prevent the wool from entering the adsorption chamber. When the flap is rotated to a position in contact with the scraper surface again, the adsorption chamber is opened by the baffle.

[0019] Preferably, the baffle is rotatably connected to the frame, and one side of the baffle is located on the rotation path of the flap, and a docking torsion spring is sleeved at the rotation connection between the baffle and the frame. When the docking torsion spring is not deformed, the side of the baffle close to the flap tilts upward and makes the baffle cover the open position of the adsorption chamber.

[0020] By adopting the above technical solution, when the flap is attached to the scraper surface, the side of the baffle close to the flap is pressed by the flap and rotated to a position parallel to the flap surface. At this time, the open position of the adsorption chamber is in an open state, and when the flap moves toward the bonding plate, the flap releases the pressure on the baffle, so that the baffle tilts under the elastic force of the docking torsion spring, thereby allowing the baffle to block the wool material subsequently scraped off by the scraper.

[0021] Preferably, it further comprises a detector, a controller and an alarm, wherein the detector and the alarm are electrically connected to the controller, the detector is used to detect the thickness of the adhesive plate, and the controller is used to control the opening and closing of the alarm based on the thickness of the adhesive plate detected by the detector.

[0022] By adopting the above technical solution, the detector and the controller are used to automatically determine whether the thickness of the rough material on the surface of the adhesive plate has reached the level that requires replacement of the adhesive plate. If so, the alarm can be activated to remind the operator to replace the adhesive plate.

[0023] Preferably, the lint-adhering roller is rotatably connected to a frame, and a contact spring is provided between the lint-adhering roller and the frame, and the lint-adhering roller contacts the surface of the grinding roller through the elastic force of the contact spring.

[0024] By adopting the above technical solution, the elastic force of the abutting spring is used to press the hair-sticking roller against the surface of the sanding roller, so as to optimize the adhesion strength of the hair material on the surface of the sanding roller by increasing the abutting force on the sanding roller, so that the hair material can be smoothly detached.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Since the scraper and the sticky roller both contact the surface of the sanding roller, when the sanding roller rotates, the scraper can first scrape the surface of the sanding roller to make most of the wool separate from the sanding roller. Then, as the sanding roller rotates, the sticky roller can be used to adhere to the residual wool on the surface of the sanding roller. Finally, the scraper and the sticky roller cooperate to reduce the amount of wool attached to the surface of the sanding roller, thereby optimizing the sanding effect of the sanding roller on subsequent fabrics. 2. The adsorption chamber formed by the enclosure and the scraper can be used to collect the hair material scraped off by the scraper, and the adsorption piece can be used to accelerate the adsorption of the aforementioned fallen hair material into the adsorption chamber, thereby reducing the accumulation of hair material at the end of the scraper, thereby affecting the scraping effect of the scraper on the grinding roller; in addition, since the open position of the adsorption chamber faces the surface of the grinding roller, the adsorption piece can also be used to absorb the hair material on the surface of the grinding roller by adsorption, thereby further reducing the amount of hair material attached to the surface of the grinding roller.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a sanding device for fabric production. Figure 1 and Figure 2 The fabric production sanding equipment includes a frame 1, on which a conveying roller group 11 is arranged. The conveying roller group 11 includes at least two groups, and each conveying roller group 11 includes at least two conveying rollers rotatably connected to the frame 1, and a motor for driving the conveying rollers to rotate. A gap for the fabric to pass through is reserved between the two conveying rollers belonging to the same conveying roller group 11. A sanding roller 12 is rotatably connected to the frame 1, and one end of the sanding roller 12 is connected to a motor for driving the sanding roller 12 to rotate. The sanding roller 12 is located between the two conveying roller groups 11; a pressure roller 13 is arranged on the side wall of the frame 1 and above the sanding roller 12, and a gap for the fabric to pass through is reserved between the pressure roller 13 and the sanding roller 12. During the conveying process of the fabric, the pressure roller 13 presses the fabric against the surface of the sanding roller 12, and generates relative friction between the fabric and the sanding roller 12 through the rotation of the sanding roller 12, thereby realizing the formation of a fluff layer on the surface of the fabric.

[0033] Reference Figure 2 and Figure 3 The frame 1 is also provided with a scraper 2 and a lint-sticking roller 3, which are sequentially arranged on the outer periphery of the sanding roller 12 along the rotation direction of the sanding roller 12, and the scraper 2 and the lint-sticking roller 3 both abut against the side wall of the sanding roller 12. Specifically, a docking block 31 is rotatably connected to the end of the lint-sticking roller 3, and an abutting spring 32 is commonly connected between the docking block 31 and the frame 1. The docking block 31 is slidably connected to the frame 1 through the abutting spring 32, and the sliding direction of the docking block 31 is parallel to the radial direction of the sanding roller 12. The lint-sticking roller 3 always abuts against the surface of the sanding roller 12 under the elastic force of the abutting spring 32. The surface of the lint-sticking roller 3 is provided with an adhesive layer 33 for adhering the wool material along its circumference. The adhesive layer 33 can specifically be a sticky tape. One end of the adhesive layer 33 away from the lint-sticking roller 3 is wrapped with a collecting roller 34. The collecting roller 34 is rotatably connected to the frame 1. Motors are provided at the ends of the lint-sticking roller 3 and the collecting roller 34 to drive the lint-sticking roller 3 and the collecting roller 34 to rotate.

[0034] Reference Figure 3 and Figure 4 A surrounding plate 4 is also provided on the frame 1. The surrounding plate 4 and the scraper 2 together enclose an adsorption chamber 41, and one side of the adsorption chamber 41 is open, and the open position faces the surface of the grinding roller 12. A baffle 42 is provided on the side wall of the frame 1 near the open position of the adsorption chamber 41. The baffle 42 penetrates the scraper 2, and the baffle 42 is rotatably connected to the side wall of the frame 1 through a rotating shaft. A docking torsion spring 43 is sleeved on the outside of the rotating shaft, and the docking spring 43 is connected between the baffle 42 and the frame 1; and when the docking torsion spring 43 is not deformed, the side of the baffle 42 away from the grinding roller 12 is tilted upward and covers the open position of the adsorption chamber 41.

[0035] Reference Figure 3 and Figure 4 A side wall of the scraper 2 facing the adsorption chamber 41 is also rotatably connected to a flap 45 and a rotating member 5 for driving the flap 45 to rotate. The rotating member 5 includes a rotating rod 51, a gear 52, a rack 53, a reset torsion spring 54 and a cam 55. The cam 55 is fixedly sleeved on the end of the sanding roller 12 and is coaxially arranged with the sanding roller 12. The rack 53 is slidably connected to the frame 1, and the rack 53 is meshingly connected to the gear 52. The gear 52 is fixedly sleeved on the rotating rod 51. The rotating rod 51 is rotatably connected to the adsorption chamber 41, and the flap 45 is connected to the side wall of the rotating rod 51. The reset torsion spring 54 is sleeved on the outside of the rotating rod 51, and the reset torsion spring 54 is connected between the rotating rod 51 and the flap 45. When the reset torsion spring 54 is not deformed, the flap 45 presses against the surface of one side of the baffle 42 so that the surface of the baffle 42 is parallel to the surface of the flap 45. At this time, the open position of the adsorption chamber 41 is in an open state. At this time, the end of the rack 53 is located on the rotation path of the cam 55 when it rotates with the sanding roller 12.

[0036] Reference Figure 3 and Figure 4 The inner wall of the adsorption chamber 41 is also detachably connected with an adhesive plate 46, and the side wall of the adhesive plate 46 facing the adsorption chamber 41 is detachably connected with an adhesive layer 33 for bonding the wool material. The adhesive plate 46 is located on the rotation path of the flap 45. When the cam 55 rotates to contact the rack 53 and pushes the rack 53, the rack 53 drives the rotating rod 51 and the gear 52 to rotate, thereby causing the flap 45 to rotate in the direction close to the adhesive plate 46 until it is in contact with the surface of the flap 45. The cam 55 then breaks away from the resistance to the rack 53. At this time, the elastic force of the reset torsion spring 54 is used to drive the flap 45 to reverse and reset.

[0037] Reference Figure 1 and Figure 4The side wall of the enclosure 4 is also provided with a detector 6, which can be specifically a distance measuring sensor for detecting the distance between it and the surface of the adhesive plate 46. The detector 6 is electrically connected to a controller 7, and the controller 7 is also electrically connected to an alarm 8. The controller 7 is used to obtain the detection result of the detector 6, so as to know the thickness of the adhesive plate 46, and then compare the detected thickness of the adhesive plate 46 with the reference thickness. If the thickness of the adhesive plate 46 exceeds the reference thickness, the alarm 8 is controlled to start, so that the operator removes the adhesive plate 46 from the enclosure 4 and replaces the adhesive layer 33 on the adhesive plate 46.

[0038] Reference Figure 4 An adsorption component 47 is also provided in the adsorption chamber 41. The adsorption component 47 includes a fan 471 and a filter 472. The air inlet of the fan 471 is connected to the adsorption chamber 41 through a pipeline. The filter 472 is located at the connection point between the air inlet of the fan 471 and the adsorption chamber 41, and the filter 472 is located on the rotation path of the end of the flap 45, so that the end wall of the flap 45 scrapes the filter 472 during the rotation; the air outlet of the fan 471 is toward the position where the sanding roller 12 and the scraper 2 conflict with each other, so as to extract the air in the adsorption chamber 41 and blow it to the surface of the sanding roller 12.

[0039] The implementation principle of the sanding equipment for fabric production in the embodiment of the present application is as follows: the fabric is conveyed by a conveying roller group 11, and the sanding roller 12 is driven to rotate in advance. When the fabric passes through the gap between the sanding roller 12 and the pressure roller 13, the sanding process is achieved through the friction of the sanding roller 12. In this process, as the sanding roller 12 rotates, the scraper 2 scrapes the surface of the sanding roller 12 to scrape most of the wool attached to the surface of the sanding roller 12 off the surface of the sanding roller 12, and then the wool sticking roller 3 is used to further adhere to the surface of the sanding roller 12. , so that the hair material remaining on the surface of the sanding roller 12 can be adhered to the adhesive layer 33, the hair-sticking roller 3 can be rotated regularly (in this embodiment, the rotation directions of the hair-sticking roller 3 and the sanding roller 12 are opposite), so that the adhesive layer 33 of the hair material of the hair-sticking roller 3 is wound around the collecting roller 34, and the adhesive layer 33 without the hair material adhered is transferred to the outer surface of the hair-sticking roller 3. In this process, even if the outer diameter of the hair-sticking roller 3 is gradually reduced, the elastic force of the abutting spring 32 can always make the hair-sticking roller 3 abut against the surface of the sanding roller 12.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
