Technical Field

[0001] This utility model relates to the field of papermaking felt processing technology, and in particular to a burr removal device for papermaking felt. Background Technology

[0002] Papermaking felts are key consumables used in the papermaking industry for paper web dewatering, forming, and transfer. Their surface quality directly affects the paper forming effect and the operating efficiency of the paper machine. As a core component of the paper machine's press section, modern papermaking felts need to have high porosity, strong wear resistance, and uniform surface characteristics to meet the stringent requirements of high-speed paper machines for dewatering performance and product consistency. With the development of papermaking equipment towards wider widths and higher speeds, the burr treatment process on the felt surface has become a key factor affecting the stable operation of the paper machine.

[0003] Existing deburring technologies mostly employ a single-process manual intervention mode, which leads to untreated areas when manually treating the surface of papermaking felts. Therefore, a deburring device for papermaking felts is provided to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem of missed processing areas in the existing technology, and to propose a burr treatment device for papermaking felt.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A burr removal device for papermaking felt includes a conveyor belt, an adjustment component above the conveyor belt, and multiple parallel burr cutters mounted on the adjustment component. The multiple burr cutters work in conjunction with the conveyor belt to remove burrs, impurities, and loose fibers from the surface of the papermaking felt. A smoothing component is mounted on the conveyor belt.

[0007] The conveyor belt is equipped with an impurity collection box and a main fan on its top, and the bottom sides of the adjustment component are connected to the main fan and the top of the impurity collection box, respectively.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] like Figure 1-6 As shown, this utility model provides a burr removal device for papermaking blankets, including a conveyor belt 1, an adjustment component 5 above the conveyor belt 1, and multiple parallel burr cutting pieces 6 installed on the adjustment component 5. The multiple burr cutting pieces 6 work with the conveyor belt 1 to remove burrs, impurities and loose hairs from the surface of the papermaking blanket. A smoothing component 2 is installed on the conveyor belt 1.

[0028] The top of the conveyor belt 1 is also equipped with an impurity collection box 4 and a main fan 3, and the two sides of the bottom of the adjustment component 5 are respectively connected to the top of the main fan 3 and the impurity collection box 4.

[0029] In this embodiment, the smoothing component 2 includes four limiting slide rails 25 and two first support frames 21. Each of the four limiting slide rails 25 is slidably connected to a damping block 22. The first support frame 21 is connected to the top of two adjacent damping blocks 22, and a smoothing roller 24 is rotatably connected between two adjacent damping blocks 22. A handle 23 is installed on one of the two damping blocks 22.

[0030] The damping blocks 22, supported by four limiting slide rails 25, together with the first support frame 21 and the damping blocks 22, can be used to position the two smoothing rollers 24. Pulling the handle 23 can temporarily adjust the height of the smoothing rollers 24. Finally, the friction between the damping blocks 22 and the inner wall of the limiting slide rails 25 forms support, ensuring a good smoothing effect for papermaking felts of different thicknesses.

[0031] In this embodiment, the impurity collection box 4 is located at the air outlet of the main fan 3.

[0032] In this embodiment, the adjustment component 5 includes two second support frames 51, with a threaded rod 54 and three support rods 52 rotatably connected between the two second support frames 51. Support sliders 53 are slidably connected to the three support rods 52. A servo motor 57 is also installed on the second support frame 51. The output shaft of the servo motor 57 is connected to the threaded rod 54 through a coupling. Two electric push rods 55 are also installed on the support slider 53. A connecting slider 56 is provided below the support slider 53. The bottom end of the output shaft of the electric push rod 55 is connected to the connecting slider 56.

[0033] The second support frame 51 and support rod 52 achieve the limiting and support effect of the support slider 53. When the servo motor 57 rotates, the rotation of the threaded rod 54 drives the support slider 53 to move back and forth. Changing the forward and reverse rotation of the servo motor 57 enables the support slider 53 to drive the burr cutting parts 6 to move back and forth. The electric push rod 55 on the support slider 53 is connected to the connecting slider 56. The telescopic electric push rod 55 can drive multiple burr cutting parts 6 to rise or fall, and adjust the height to adapt to papermaking blankets of different thicknesses.

[0034] In this embodiment, the burr cutting component 6 includes a connecting plate 61. Threaded connecting blocks 63 are installed on both sides of the connecting plate 61. The connecting plate 61 is fixedly connected to the bottom of the connecting slider 56 through the threaded connecting blocks 63. A razor 62 is hinged to the bottom of the connecting plate 61. An auxiliary fan 64 is installed on the bottom of the connecting plate 61. Side brackets 65 are installed on both sides of the connecting plate 61. Multiple positioning holes are opened on the two side brackets 65. Positioning rods 66 are provided on the opposite side of the two side brackets 65. The two positioning rods 66 pass through the positioning holes on the adjacent side brackets 65 and engage with the surface of the razor 62.

[0035] The connecting plate 61, threaded connecting block 63, and connecting slider 56 are connected to establish the connection between the adjusting component 5 and the burr cutting component 6. Secondly, the side bracket 65 and positioning rod 66 can adjust the burr processing angle of the razor 62 according to actual needs, so that the razor 62 can be kept at the optimal processing angle. In addition, the auxiliary fan 64 can blow the burrs processed by the razor 62 toward the impurity collection box 4, and work with the main fan 3 to achieve a better burr pushing effect.

[0036] Furthermore, the operation of the conveyor belt 1, the adjusting component 5, and the burr cutter 6 needs to be logical. When the conveyor belt 1 starts, the burr cutter 6 and the adjusting component 5 remain stationary. When the burr cutter 6 moves a certain distance, which is exactly the working width of multiple burr cutters 6, the conveyor belt 1 stops and the adjusting component 5 works to drive the burr cutter 6 to move back and forth to scrape off the loose fibers on the surface of the blanket once.

[0037] How to use and how to work this device:

[0038] When in use, the device uses conveyor belt 1 in conjunction with smoothing component 2 to transport and smooth the burrs on the surface of the papermaking felt. Then, adjusting component 5 cooperates with burr cutting component 6 to scrape off the burrs on the felt surface. In addition, the operation of conveyor belt 1 enables a streamlined operation for scraping burrs on the felt surface, which is more efficient.

[0039] Inside the smoothing component 2, the damping blocks 22 supported by four limiting slide rails 25, together with the first support frame 21 and the damping blocks 22, can achieve the positioning of the two smoothing rollers 24, and pulling the handle 23 can temporarily adjust the height of the smoothing rollers 24. Finally, the friction generated between the damping blocks 22 and the inner wall of the limiting slide rails 25 forms support, ensuring a good smoothing effect for papermaking blankets of different thicknesses.

[0040] Within the adjustment assembly 5, the second support frame 51 and the support rod 52 achieve the limiting and support effect for the support slider 53. When the servo motor 57 rotates, the rotation of the threaded rod 54 drives the support slider 53 to move back and forth. Changing the forward and reverse rotation of the servo motor 57 enables the support slider 53 to drive the burr cutting piece 6 to move back and forth. Furthermore, the electric push rod 55 on the support slider 53 is connected to the connecting slider 56, which can drive multiple burr cutting pieces 6 to rise or fall through the telescopic electric push rod 55, adjusting the height to adapt to papermaking blankets of different thicknesses.

[0041] Inside the burr cutting component 6, firstly, the connecting plate 61, the threaded connecting block 63, and the connecting slider 56 are connected to establish the connection between the adjusting component 5 and the burr cutting component 6. Secondly, the side bracket 65 and the positioning rod 66 can adjust the burr processing angle of the razor 62 according to actual needs. Finally, the razor 62 can be kept at the optimal processing angle. In addition, with the auxiliary fan 64, the burrs processed by the razor 62 can be blown towards the impurity collection box 4, which works with the main fan 3 to achieve a better burr pushing effect.

[0042] The main fan 3 and the impurity collection box 4 work together with the auxiliary fan 64 to collect burrs, impurities and floating hair into the impurity collection box 4 after the burr cutting part 6 has finished processing the burrs. A storage box can be placed at the bottom of the impurity collection box 4 to collect and process the burrs, impurities and floating hair in a centralized manner.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
