Description

Technical Field

[0001] This utility model relates to the field of dust removal devices for slitting mechanisms, and more particularly to an independent dust collection device for a slitting mechanism. Background Technology

[0002] A slitting machine is a mechanical device that cuts wide sheets of paper, mica tape, or film into multiple narrow strips. It is commonly used in papermaking machinery, wire and cable mica tape production, and printing and packaging machinery. During the cutting process, dust is easily generated, which can pollute the environment and affect health; therefore, timely dust removal is essential.

[0003] Existing dust removal devices commonly include brush dust collection, negative pressure ventilation, and combinations of the two. While the combination of brush dust collection and negative pressure ventilation is more effective than using either method alone, the dust removal efficiency is still generally low, leaving significant room for improvement. This is especially true when cutting narrow materials, where the spacing between suction ports cannot be adjusted on the same machine. Some suction ports are not facing the cutting edge, meaning they are not directly in contact with the dusty area. Furthermore, some suction ports are not facing the cutting edge, resulting in wasted airflow and inefficient use of the exhaust fan's air supply, leading to mediocre dust removal.

[0004] Therefore, it is necessary to provide an independent dust collection device for the slitting mechanism to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the problem that existing dust removal devices have mediocre dust removal effects, especially when cutting narrow materials, some dust suction ports do not face the cutting blade position, that is, some dust suction ports do not face the dust area space, and the air source of the exhaust fan cannot be effectively utilized, resulting in inefficient dust removal and mediocre dust removal effect, this utility model provides an independent dust suction device for the cutting mechanism.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An independent dust collection device for a cutting mechanism includes a dust collector inlet pipe and several air pipes connected together, as well as several bamboo-joint universal tubes and several switches. The bamboo-joint universal tubes have a universal adjustment function. The number of the switches is equal to the number of the bamboo-joint universal tubes. The switches are installed at the end of the bamboo-joint universal tubes away from the cutter and can control the airflow. The switches are connected to the air pipes.

[0008] As a further embodiment of this utility model: the bamboo-joint universal tube includes a suction port and a bamboo-joint tube connected together, the bamboo-joint tube can be repeatedly bent and shaped, and the distance between each adjacent suction port can be adjusted.

[0009] As a further aspect of this utility model, the material of the bamboo-joint tube is POM.

[0010] As a further embodiment of this utility model, it also includes a gathering tube, through which the switch and several of the air pipes are connected, and the gathering tube is used to transfer dust.

[0011] As a further embodiment of this utility model: the diameter of the air inlet pipe of the dust collector is significantly larger than the diameter of the air pipe, and the diameter of the air pipe is significantly larger than the diameter of the bamboo joint universal tube, both of which facilitate the collection of dust using an exhaust fan air source.

[0012] As a further embodiment of this utility model, the diameters of the dust collector's air inlet pipe, air pipe, and bamboo-joint universal tube are 100mm, 50mm, and 20mm, respectively.

[0013] As a further aspect of this utility model: the number of air tubes is significantly less than the number of bamboo-joint universal tubes, which facilitates the collection of dust using an exhaust fan air source.

[0014] The beneficial effects of the independent dust collection device of the slitting mechanism involved in this utility model are as follows:

[0015] This invention incorporates several switches. When the width of the film to be cut is narrow, some switches can be closed, leaving only the switches near the cutting blade open. This allows for efficient use of the exhaust fan's air supply, concentrating the airflow to collect dust. Therefore, it solves the problem of unsatisfactory dust removal efficiency in existing systems. It possesses the advantage of efficiently utilizing the air supply and improving dust collection efficiency. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0025] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "center," "longitudinal," "lateral," "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7As shown, an independent dust collection device 100 for a cutting mechanism includes a dust collector inlet pipe 150 and several air pipes 140 connected together, as well as a gathering pipe 130, several bamboo-joint universal tubes 110, and several switches 120. The bamboo-joint universal tubes 110 have a universal adjustment function; the number of the several switches 120 is equal to the number of the bamboo-joint universal tubes 110; the several switches 120 are installed at the end of the bamboo-joint universal tubes 110 away from the cutter 220, and can control the airflow size; the several switches 120 are connected to the several air pipes 140.

[0028] Specifically, the dust collector inlet pipe 150 includes an inlet pipe body 151 and a dust collector interface 152 provided on the inlet pipe body 151 for connecting the dust collector.

[0029] This invention, by incorporating several switches 120, allows for the closure of some switches 120 when the width of the film to be cut 230 is narrow, leaving only the switches 120 near the cutter 220 open. This effectively utilizes the air supply from the exhaust fan, concentrating the airflow to collect dust. Therefore, it solves the problem of unsatisfactory dust removal efficiency in existing systems. It possesses the advantage of effectively utilizing the air supply and improving dust collection efficiency.

[0030] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the bamboo joint universal tube 110 includes a suction port 111 and a bamboo joint tube 112 connected together. The bamboo joint tube 112 can be repeatedly bent and shaped, and the spacing between each adjacent suction port 111 can be adjusted.

[0031] The bamboo-joint tube 112 is bent at a 90-degree angle near the dust suction port 111, which helps to optimize the overall spatial structure of the cutting mechanism. Replacing the existing dust suction tube with the bamboo-joint universal tube 110 allows the bamboo-joint tube 112 to be repeatedly bent and shaped. The spacing between adjacent bamboo-joint tubes 112 can be adjusted according to the width of the membrane 230, ensuring that each dust suction port 111 is close to the cutter 220, facilitating centralized airflow from the exhaust fan and efficient dust absorption.

[0032] Preferably, the bamboo-joint tube 112 is made of POM.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, specifically, several of the switches 120 and several of the air pipes 140 are connected through the collecting pipe 130, which is used to transfer dust.

[0034] Specifically, the collecting pipe 130 is arranged parallel to the dust collector inlet pipe 150 and is located on the dust collector inlet pipe 150. A plurality of air pipes 140 are connected between the collecting pipe 130 and the dust collector inlet pipe 150.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the diameter of the dust collector inlet pipe 150 is significantly larger than the diameter of the air pipe 140, and the diameter of the air pipe 140 is significantly larger than the diameter of the bamboo joint universal pipe 110, both of which facilitate the collection of dust using the exhaust fan air source.

[0036] Preferably, the diameters of the dust collector inlet pipe 150, the air pipe 140, and the bamboo joint universal pipe 110 are 100mm, 50mm, and 20mm, respectively.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 7 As shown, the number of air tubes 140 is significantly less than the number of bamboo-joint universal tubes 110, which facilitates the collection of dust using an exhaust fan. Preferably, the ratio of the number of air tubes 140 to the number of bamboo-joint universal tubes 110 is 1:3.

[0038] In use, the independent dust collection device 100 of the slitting mechanism is installed on the slitting machine body 200. The spacing between each cutter 220 and each of the bamboo-joint universal tubes 110 is adjusted according to the width of the winding 210 and the slitting width. Then, some of the switches 120 are opened or closed according to the width of the winding 210 to make reasonable use of the air source of the exhaust fan and concentrate the airflow to collect dust. This improves the efficiency of dust collection.

[0039] The above description of the utility model is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
