Description

Technical Field

[0001] The utility model relates to a dust removal device, in particular to an electrostatic dust removal device for fabrics. Background Technique

[0002] Fabric refers to the fabric used to manufacture various textiles such as clothing, household items, and decorations. It is usually made of fibers through weaving, knitting, or non-woven processes. There are many types of fabrics, which can be classified according to materials, structures, uses, etc. After the fabric is produced, it needs to be wound up. When winding up the fabric, it is necessary to perform a dust removal operation on the fabric to ensure that the wound-up fabric does not contain too much dust. The fabric dust removal device includes electrostatic dust removal and vacuum cleaner dust removal.

[0003] Currently, when using electrostatic dust removal for fabrics, it cannot effectively remove the dust in the gaps of the fabric. Since there will be gaps between the wires during the knitting production of the fabric, small dust will get stuck in the gaps, resulting in the inability to adsorb and remove the dust in the gaps when using electrostatic dust removal, thus affecting the dust removal effect. Summary of the Invention

[0004] The purpose of the utility model is to provide an electrostatic dust removal device for fabrics to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An electrostatic dust removal device for fabrics, comprising: a base, on both sides of the base are symmetrically arranged transmission members, and the movement transmission directions of the two transmission members are the same;

[0007] Vertically symmetrically arranged electrostatic dust removal mechanisms are arranged between the two transmission members. The two vertically symmetrically arranged electrostatic dust removal mechanisms are arranged on the base in a direction perpendicular to the movement transmission direction of the transmission members, and a dust suction fixing mechanism is arranged on the top of the base;

[0008] A driving mechanism is arranged on the dust suction fixing mechanism, and the driving mechanism is rotationally connected to two flapping dust suction mechanisms. The driving mechanism drives the two flapping dust suction mechanisms to perform alternating reciprocating lifting movements;

[0009] The two flapping dust suction mechanisms are arranged on both sides of the two vertically symmetrically arranged electrostatic dust removal mechanisms, and the flapping dust suction mechanisms are connected to the dust suction fixing mechanism.

[0010] For the electrostatic dust removal device for fabrics as described above: the two transmission members both include a conveying frame and a first servo motor. The conveying frame is arranged on the base, and one end of the conveying frame is provided with a first servo motor, and the first servo motor is connected to the outer wall of the base.

[0011] The fabric static electricity dust removal device as described above: Each of the two static electricity dust removal mechanisms includes a rubber roller, a second servo motor, a static electricity dust removal roller, and a gear. One end of the rubber roller is connected to the output shaft of the second servo motor. Static electricity dust removal rollers are in contact connection on both sides of the rubber roller. Gears are connected to the central shafts of the rubber roller at the end away from the second servo motor and the two static electricity dust removal rollers in contact connection on both sides of the rubber roller. The three gears are meshed with each other in pairs. The central shafts of the rubber roller and the static electricity dust removal rollers are rotatably connected to the inner wall of the cavity of the base, and the second servo motor is connected to the outer wall of the base.

[0012] The fabric static electricity dust removal device as described above: The dust suction fixing mechanism includes a fixed top plate, a rigid dust suction pipe, and a fixed rod. Four rigid dust suction pipes are connected to the fixed top plate in a rectangular array. The heights of the two rigid dust suction pipes on one side are higher than those of the two rigid dust suction pipes on the other side. Three fixed rods are connected to the fixed top plate at equal intervals.

[0013] The fabric static electricity dust removal device as described above: The driving mechanism includes a crankshaft and a third servo motor. One end of the crankshaft is connected to the output shaft of the third servo motor.

[0014] The fabric static electricity dust removal device as described above: The crankshaft is rotatably connected to three fixed rods arranged at equal intervals, and the third servo motor is connected to the outermost fixed rod.

[0015] The fabric static electricity dust removal device as described above: Each of the two flapping dust suction mechanisms includes a dust suction frame, a dust suction hole, a central rod, an insertion pipe, and a linkage block. The dust suction frame is arranged as a hollow cavity. Dust suction holes are arranged on the upper and lower sides of the inner wall of the dust suction frame. A central rod is arranged at the central part on one side of the dust suction frame. Insertion pipes are integrally formed on the dust suction frame on both sides of the central rod. A linkage block is rotatably arranged at the top of the central rod.

[0016] The fabric static electricity dust removal device as described above: The insertion pipes are slidably inserted into two rigid dust suction pipes parallel to the static electricity dust removal mechanism in the cavity of the base. The insertion pipe of one of the flapping dust suction mechanisms is slidably connected to one of the rigid dust suction pipes of the dust suction fixing mechanism. The two linkage blocks are rotatably connected to the crankshaft.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] By arranging flapping dust suction mechanisms on both sides of the electrostatic dust removal mechanism, when the driving mechanism operates, the crankshaft can drive the linkage block to move. Since the insertion pipe is inserted into the rigid dust suction pipe, the insertion pipe can limit the vertical reciprocating lifting of the dust suction frame, so that the upper and lower sides of the inner wall of the dust suction frame can flap on the fabric. By connecting the rigid dust suction pipe to an industrial vacuum cleaner outside and connecting the rigid dust suction pipe to the insertion pipe, when the dust suction frame flaps on the fabric, the dust in the fabric gaps can be sucked out. The fabric after further dust removal passes through the electrostatic dust removal mechanism again for dust removal, which can improve the dust removal effect. By arranging the flapping dust suction mechanisms on both sides of the electrostatic dust removal mechanism, dust suction treatment can be carried out when the fabric enters and leaves the electrostatic dust removal mechanism, improving the dust removal effect on the fabric.

Specific embodiments

[0032] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0033] The special term "exemplary" herein means "serving as an example, embodiment, or illustration". Any embodiment described as "exemplary" herein does not have to be construed as superior or better than other embodiments.

[0034] In addition, for a better description of the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can be implemented without some specific details. In some instances, methods, means, and elements well known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0035] Please refer to Figures 1 to 12 , in the embodiment of the present utility model, a fabric electrostatic dust removal device includes: a base 1, two conducting members 2 are symmetrically arranged on both sides of the base 1, and the movement transmission directions of the two conducting members 2 are the same;

[0036] An electrostatic dust removal mechanism 3 is vertically symmetrically arranged between the two conducting members 2, and the two vertically symmetrically arranged electrostatic dust removal mechanisms 3 are arranged on the base 1 in a manner perpendicular to the movement transmission direction of the conducting members 2. A dust suction fixing mechanism 4 is arranged on the top of the base 1;

[0037] A driving mechanism 5 is arranged on the dust suction fixing mechanism 4, and the driving mechanism 5 is rotationally connected to two flapping dust suction mechanisms 6. The driving mechanism 5 drives the two flapping dust suction mechanisms 6 to alternately move up and down reciprocally;

[0038] The two flapping dust suction mechanisms 6 are arranged on both sides of the two vertically symmetrically arranged electrostatic dust removal mechanisms 3, and the flapping dust suction mechanisms 6 are connected to the dust suction fixing mechanism 4.

[0039] In this embodiment, a control panel is provided on the base 1, and each component of the device is electrically connected to the control panel through a transmission wire. The operating state of the device is controlled through the control panel. When dust removal is performed on the fabric, the two first servo motors 202 can make the movement transmission directions of the two conveying frames 201 operate in the same direction. The fabric is placed on the conveying frame 201 that runs from the outside of the base 1 into the cavity. Through the operation of the conveying frame 201, the fabric can be introduced into the cavity of the base 1, so that the fabric passes through the inside of the dust suction frame 601, then passes between the two electrostatic dust removal mechanisms 3, and then passes through the dust suction frame 601 on the other side, and finally is placed on the conveying frame 201 that runs from the inside of the base 1 to the outside and is transmitted.

[0040] Through the operation of the third servo motor 502, the crankshaft 501 can rotate on the fixed rod 403. The crankshaft 501 is rotatably connected to the linkage block 605, and the linkage block 605 is rotatably connected to the central rod 603. The insertion pipes 604 on both sides of the dust suction frame 601 are inserted into the rigid dust suction pipe 402. The rigid dust suction pipe 402 can limit the insertion pipes 604. Thus, when the crankshaft 501 drives the linkage block 605 to move up and down, the insertion pipes 604 are vertically inserted and lifted in the rigid dust suction pipe 402, so that the upper and lower sides of the inner wall of the dust suction frame 601 circulate and beat on the upper and lower sides of the fabric. The rigid dust suction pipe 402 is connected to an industrial vacuum cleaner outside, and the rigid dust suction pipe 402 is communicated with the insertion pipes 604.

[0041] The insertion pipe 604 is communicated with the hollow dust suction frame 601. Therefore, when the inner wall of the dust suction frame 601 contacts the fabric, dust can be sucked in through the dust suction holes 602, so that the dust on the fabric is adsorbed and removed. Through the cyclic beating of the inner wall of the dust suction frame 601 on the fabric, the dust in the fabric gaps can be removed. The two dust suction frames 601 are alternately lifted and lowered. When the preliminarily dust-removed fabric moves between the two electrostatic dust removal mechanisms 3, the second servo motor 302 is driven to make the rubber roller 301 rotate. Through the linkage and engagement of the gears 304, the electrostatic dust removal roller 303 can adsorb the dust on the fabric by means of static electricity through contact with the fabric. The electrostatic dust removal roller 303 adsorbed with dust rotates and contacts the rubber roller 301, and the rubber roller 301 can adhere and remove the dust on the electrostatic dust removal roller 303, improving the electrostatic adsorption effect of the electrostatic dust removal roller 303 and the dust removal effect on the fabric. What is not described in detail in this solution is the existing publicly disclosed technical means.

[0042] As a further solution of the present invention, the two conductive members 2 both include a conveying frame 201 and a first servo motor 202. The conveying frame 201 is provided on the base 1, and a first servo motor 202 is provided at one end of the conveying frame 201. The first servo motor 202 is connected to the outer wall of the base 1.

[0043] In this embodiment, the first servo motor 202 drives the conveying rack 201 to run. When the fabric is placed on the conveying rack 201, the running conveying rack 201 can drive the fabric, so that the fabric runs into the base 1 or runs and is transmitted from the inner side to the side of the cavity of the base 1, meeting the driving use of the fabric.

[0044] As a further solution of the present utility model, the two electrostatic dust removal mechanisms 3 both include rubber rollers 301, second servo motors 302, electrostatic dust removal rollers 303 and gears 304. One end of the rubber roller 301 is connected to the output shaft of the second servo motor 302. Electrostatic dust removal rollers 303 are in contact connection on both sides of the rubber roller 301. Gears 304 are connected to the central axes of the rubber roller 301 at the end away from the second servo motor 302 and the two electrostatic dust removal rollers 303 in contact connection on both sides of the rubber roller 301. The three gears 304 are meshed with each other in pairs. The central axes of the rubber roller 301 and the electrostatic dust removal rollers 303 are rotatably connected to the inner wall of the cavity of the base 1, and the second servo motor 302 is connected to the outer wall of the base 1.

[0045] In this embodiment, the two symmetrically arranged electrostatic dust removal mechanisms 3 enable the fabric to pass between the two electrostatic dust removal mechanisms 3. When the two flapping and dust suction mechanisms 6 alternately lift and flap the fabric, both the upper and lower sides of the fabric can contact the electrostatic dust removal mechanisms 3 on the upper and lower sides. The rubber roller 301 can drive the two electrostatic dust removal rollers 303 on the same side to rotate through the gears 304, so that the part of the electrostatic dust removal roller 303 that adsorbs dust after contacting the fabric can rotate to the position of the rubber roller 301. The rubber roller 301 can adhere and remove the dust on the electrostatic dust removal roller 303, improving the electrostatic adsorption effect of the electrostatic dust removal roller 303 and preventing too much dust from adhering to the electrostatic dust removal roller 303 and affecting the electrostatic adsorption force.

[0046] As a further solution of the present utility model, the dust suction fixing mechanism 4 includes a fixed top plate 401, a rigid dust suction pipe 402 and a fixed rod 403. Four rigid dust suction pipes 402 are connected to the fixed top plate 401 in a rectangular array. The heights of the two rigid dust suction pipes 402 on one side are higher than those of the two rigid dust suction pipes 402 on the other side. Three fixed rods 403 are connected to the fixed top plate 401 at equal intervals.

[0047] In this embodiment, one end of the rigid dust suction pipe 402 is used to connect to the pipe of an external industrial vacuum cleaner. By operating the external industrial vacuum cleaner, when the beating dust suction mechanism 6 beats the fabric, the dust in the fabric gaps can be sucked out, improving the dust removal effect. The fixed rod 403 is used for the rotational connection of the crankshaft 501. The three fixed rods 403 arranged in an equidistant straight line are respectively rotationally connected to the two ends and the middle part of the crankshaft 501, without hindering the rotation of the crankshaft 501. The outermost fixed rod 403 is connected to the third servo motor 502 to meet the installation requirements of the third servo motor 502.

[0048] As a further solution of the present utility model, the driving mechanism 5 includes a crankshaft 501 and a third servo motor 502. One end of the crankshaft 501 is connected to the output shaft of the third servo motor 502. The crankshaft 501 is rotationally connected to three fixed rods 403 arranged at equal intervals, and the third servo motor 502 is connected to the outermost fixed rod 403.

[0049] In this embodiment, two connecting rod journals are provided on the crankshaft 501, and the two connecting rod journals are arranged alternately up and down. When the third servo motor 502 drives the crankshaft 501 to rotate, the two connecting rod journals rotate reciprocally up and down alternately, meeting the driving requirements of the beating dust suction mechanism 6.

[0050] As a further solution of the present utility model, both of the two beating dust suction mechanisms 6 include a dust suction frame 601, dust suction holes 602, a central rod 603, insertion pipes 604 and linkage blocks 605. The dust suction frame 601 is arranged as a hollow cavity. Dust suction holes 602 are provided on both the upper and lower sides of the inner wall of the dust suction frame 601. A central rod 603 is provided at the central part on one side of the dust suction frame 601. Insertion pipes 604 are integrally formed on the dust suction frame 601 on both sides of the central rod 603. A linkage block 605 is rotatably provided at the top of the central rod 603. The insertion pipes 604 are slidably inserted into two rigid dust suction pipes 402 that are parallel to the electrostatic dust removal mechanism 3 in the cavity of the base 1. The insertion pipes 604 of the beating dust suction mechanism 6 are slidably connected to the rigid dust suction pipes 402 of the dust suction fixing mechanism 4. The two linkage blocks 605 are rotatably connected to the crankshaft 501.

[0051] In this embodiment, the fabric is passed through the dust suction frame 601. When the crankshaft 501 operates driven by the third servo motor 502, the linkage block 605 rotatably connected to the connecting rod journal part of the crankshaft 501 will move up and down. The linkage block 605 is connected to the central rod 603, and the insertion pipe 604 is slidably inserted into the rigid dust suction pipe 402. Therefore, the vertical lifting state of the dust suction frame 601 can be restricted, and the inner walls on the upper and lower sides of the dust suction frame 601 can slap the fabric, so that the dust in the fabric gaps can be slapped out. By connecting the rigid dust suction pipe 402 to an industrial vacuum cleaner outside and sucking air through the dust suction holes 602, the dust slapped out from the fabric can be adsorbed, improving the cleaning effect of the dust in the fabric gaps.
