Description

Technical Field

[0001] This application relates to the technical field of putty powder production equipment, and in particular to a dust removal device for a putty powder production line. Background Technology

[0002] Putty powder is an indispensable basic material in building decoration projects, mainly used for smoothing and finishing base surfaces such as walls and ceilings. Its core function is to fill the pores, cracks, and uneven areas of the base surface, forming a smooth and strong coating, providing an ideal adhesion base for subsequent paints, wallpapers, and other surface materials. With the advancement of building technology and the deepening of environmental protection concepts, putty powder has gradually evolved from a traditional hand-mixed "coarse material" into a standardized and functional modern building material, becoming an important guarantee of modern building quality.

[0003] In the production process of putty powder, it is first filled into bags using a filling device, and then sealed to complete the bagging process. The bagged putty powder is then transported via conveyor belt and finally stacked, and subsequently transferred and stored or loaded onto trucks using forklifts. During the filling process, a significant amount of putty powder usually adheres to the surface of the bags, resulting in a high level of dust in the workshop air during subsequent processes, which negatively impacts the working environment. Utility Model Content

[0004] To reduce dust from bagged putty powder, this application provides a dust removal device for a putty powder production line.

[0005] The technical solution adopted in this application is as follows:

[0006] A dust removal device for a putty powder production line includes a housing, a suction unit connected to the housing, and a plurality of feeding rollers rotatably disposed in the housing. The outer wall of the feeding rollers is provided with protrusions. A power unit for driving the feeding rollers to rotate is installed on the housing. One end of the housing is a feeding end and the other end is a discharging end. The suction unit is used to generate negative pressure in the housing.

[0007] By adopting the above technical solution, the feeding roller drives the bag containing putty powder to move, thereby conveying the bag. During the rotation of the feeding roller, the protrusions can intermittently push the bag, which helps the dust on the surface of the bag to move and be drawn away by the exhaust fan, reducing the amount of dust on the surface of the bag from entering the workshop.

[0008] Optionally, the housing includes a frame and a cover disposed on the frame, the suction component is mounted on the cover, and the feeding roller is mounted on the frame.

[0009] Optionally, a mounting base is rotatably mounted in the frame, and the feeding roller is detachably mounted on the mounting base. The rotation of the mounting base synchronously drives the feeding roller to rotate. The power component is linked to the mounting base to drive the mounting base to rotate.

[0010] By adopting the above technical solution, the feeding roller can be detachably installed on the mounting base, which facilitates maintenance and replacement.

[0011] Optionally, the power component includes a rotating roller rotatably disposed in the frame, a first element for driving the rotating roller to rotate, and connecting the rotating roller and all the mounting seats to a certain synchronous belt.

[0012] By adopting the above technical solution, the feeding roller can be driven to rotate under the action of the synchronous belt, which has a simple structure and strong applicability.

[0013] Optionally, both the rotating roller and the side wall of the mounting base are provided with synchronous pulleys, the synchronous belt is connected between the synchronous pulleys, and two extrusion columns are installed on the frame between two adjacent synchronous pulleys. The distance between the two extrusion columns is smaller than the diameter of the synchronous pulleys, and the synchronous belt passes between the two extrusion columns.

[0014] By adopting the above technical solution, the interaction force between the synchronous belt and the synchronous pulley is increased, making the transmission more stable.

[0015] Optionally, the feeding roller has an internal hollow structure, the mounting base has a receiving cavity, and a positioning post is slidably disposed in the receiving cavity. The rotation of the mounting base can synchronously drive the positioning post to rotate. A driving component is installed on the frame to drive the positioning post to slide in the receiving cavity, so that one end of the positioning post is inserted into the feeding roller or stored in the receiving cavity. A support seat for supporting the feeding roller is provided at the end of the frame away from the mounting base. The positioning post is inserted into the feeding roller, and the rotation of the mounting base can synchronously drive the feeding roller to rotate.

[0016] By adopting the above technical solution, the feeding roller corresponds to the mounting base, so that the positioning pin is inserted into the feeding roller, thereby positioning the feeding roller. When disassembling, the positioning pin can be slid out of the feeding roller.

[0017] Optionally, the driving component is threadedly connected to the driving rod of the frame, one end of the driving rod extends into the receiving cavity and is rotatably connected to the positioning post. When the driving rod moves on the frame, it synchronously drives the positioning post to move.

[0018] By adopting the above technical solution, the positioning column can be moved by the drive rod.

[0019] Optionally, the positioning post is provided with a limiting strip, and the inner wall of the feeding roller and the inner wall of the receiving groove are both provided with limiting grooves for the limiting strip to slide.

[0020] By adopting the above technical solution, the positioning column and the feeding roller can rotate synchronously.

[0021] Optionally, a limiting post is threadedly connected to the inner wall of the frame on the side away from the mounting base, and one end of the limiting post can be inserted into the end of the feeding roller.

[0022] By adopting the above technical solution, the stability of the feeding roller is further improved under the action of the limiting post.

[0023] Optionally, two baffles are installed on the frame, and the two baffles pass through the cover.

[0024] By adopting the above technical solution, the movement of the bag is restricted, thereby improving the stability of bag delivery.

[0025] In summary, this application includes at least one of the following beneficial effects:

[0026] 1. As the bag enters the cover, the rotating feeding rollers better promote the movement of dust on the surface of the bag and discharge it through the exhaust fan;

[0027] 2. The feeding rollers rotate in conjunction with the synchronous belt and the mounting base, and the feeding rollers and the mounting base are detachably connected, so the synchronous belt will not affect the installation of the feeding rollers. Attached Figure Description

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] This application discloses a dust removal device for a putty powder production line. (Refer to...) Figure 1 and Figure 2 The dust removal device includes a housing 1, a suction unit 2 mounted on the upper part of the housing 1, and multiple feeding rollers 3 rotatably mounted inside the housing 1. One end of the housing 1 is the inlet end 6, and the other end is the outlet end 7. The suction unit 2 generates negative pressure inside the housing 1 and sucks away the dust. Figure 3 The housing 1 is equipped with a power unit 5 for driving the feeding roller 3 to rotate. Conveyor belts are installed at both ends of the housing 1. After the putty powder is filled, the bag enters the housing 1 through the conveyor belt at the feed end 6 and then into the housing 1. After being cleaned by the suction unit 2, it exits from the discharge end 7 and enters the subsequent conveyor belt. The housing 1 includes a frame 101 and a cover 102 mounted on the frame 101. The cover 102 has open ends, forming the feed end 6 and the discharge end 7. Flexible baffles are installed at the openings of the cover 102 to allow dust to escape. The feeding roller 3 is rotatably mounted on the frame 101 to achieve the feeding effect.

[0038] The suction component 2 is installed on the cover 102. The suction component 2 includes a suction pipe installed on the cover 102. The suction pipe is used to connect with the exhaust device, thereby generating negative pressure in the cover 102 and removing dust. The exhaust device can be a fan, a vacuum pump, or any other device that can generate suction.

[0039] Reference Figure 2 and Figure 4 The sidewall of the feeding roller 3 is provided with protrusions 4, which are preferably elongated strips and spaced apart circumferentially along the feeding roller 3. When the feeding roller 3 rotates and drives the bag body to move, the protrusions 4 can abut against the bag body, thereby promoting the dust to fall off the surface of the bag body. Furthermore, the protrusions 4 help to distribute the putty powder more evenly within the bag body, which is beneficial for subsequent bag stacking. In the gas embodiment, the protrusions can be structures such as raised dots.

[0040] Reference Figure 4 and Figure 5An mounting base 8 is rotatably mounted on the inner wall of the frame via bearings or other means. The feeding roller 3 is detachably mounted on the mounting base 8. The power component 5 drives the mounting base 8 to rotate, thereby synchronously driving the feeding roller 3 to rotate.

[0041] The power unit 5 includes a rotating roller 51 rotatably mounted in the frame 101, a first element 52 for driving the rotating roller 51 to rotate, and a synchronous belt 53 connecting the mounting base 8 and the rotating roller 51. The rotating roller 51 and the feeding roller 3 are arranged in parallel, and the first element 52 is preferably a motor and is connected to the rotating roller 51.

[0042] Both the rotating roller 51 and the mounting base 8 have synchronous pulleys 9 fixed to their side walls. A synchronous belt 53 connects all the synchronous pulleys 9 together, so that the rotation of the rotating roller 51 drives all the synchronous pulleys 9 to rotate via the synchronous belt 53. An installation groove is provided on the inner wall of the frame 101, and the mounting base 8 is rotatably mounted in the installation groove via bearings or other means. After the feeding roller 3 is mounted on the mounting base 8, the rotation of the mounting base 8 and the synchronous belt 53 cause the feeding roller 3 to rotate.

[0043] Two compression columns 10 are installed on the inner wall of the frame between two adjacent synchronous pulleys 9, and the two compression columns 10 are distributed vertically. The distance between the two compression columns 10 is less than the diameter of the synchronous pulley 9. The synchronous belt 53 passes between the two compression columns 10, and the force between the synchronous belt 53 and the synchronous pulley 9 is increased under the action of the compression columns 10.

[0044] Reference Figure 6 and Figure 7 The feeding roller 3 has a hollow internal structure. A receiving cavity 11 is provided in the mounting base 8, and a positioning post 12 is slidably mounted in the receiving cavity 11. A driving component 13 is mounted on the frame 101 to drive the positioning post 12 to slide within the receiving cavity 11. A support base 14 is mounted on the inner wall of the frame 101 away from the mounting base 8. The support base 14 has an arc-shaped structure with its opening facing upwards and is used to support the feeding roller 3. The positioning post 12 can be completely housed in the receiving cavity 11 or partially extend out of it. When the feeding roller 3 is placed in the position corresponding to the receiving cavity 11, the positioning post 12 slides out and inserts into the feeding roller 3. Both ends of the feeding roller 3 abut against the inner wall of the frame 101 and the mounting base 8, respectively, thereby positioning the feeding roller 3. The side wall of the positioning post 12 is fixed with a limiting strip 15. The inner walls of the feeding roller 3 and the receiving cavity 11 are both provided with limiting grooves 16. The limiting strip 15 can be engaged in the limiting groove 16, so that the rotation of the positioning post 12 can synchronously drive the feeding roller 3 to rotate.

[0045] The driving component 13 includes a driving rod threadedly connected to the frame 101. One end of the driving rod is threadedly connected to the frame 101, slides through the mounting base 8, and extends into the receiving cavity 11. The end of the driving rod in the receiving cavity 11 is rotatably connected to the positioning pin 12 via a bearing. Therefore, rotating the driving rod can drive the positioning pin 12 to slide.

[0046] In a further embodiment, to improve the stability of the feed roller 3, a limiting post 17 is threadedly connected to the inner wall of the frame 101 on the side away from the mounting base 8. One end of the limiting post 17 extends beyond the surface of the frame 101, facilitating rotation. One end of the limiting post 17 can be inserted into the end of the feed roller 3. When the feed roller 3 needs to be disassembled, replaced, or repaired, the limiting post 17 is rotated, causing it to slide out of the feed roller 3. To reduce friction between the limiting post 17 and the feed roller 3, lubricant can be applied to the contact surface.

[0047] Furthermore, refer to Figure 3 Two baffle plates 18 are installed on the frame 101 and are fixed to the frame 101 by bolts or other means. The two baffle plates 18 pass through the cover 102, forming a space between the baffle plates 18 for the bag to pass through, thereby limiting the movement path of the bag. Furthermore, the end of the baffle plate 18 located at the feed end 6 can be set in a flared structure, which facilitates the entry of the bag.

[0048] The implementation principle of a dust removal device for a putty powder production line according to an embodiment of this application is as follows: the bag enters the cover 102 from the feed end 6, the feed roller 3 rotates to drive the movement of the bag, and under the action of the protrusion 4, the dust on the surface of the bag is more easily raised, and then sucked away by the suction component 2.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
