Description

Technical Field

[0001] This utility model belongs to the field of slitting equipment technology, specifically relating to a self-cleaning slitting device. Background Technology

[0002] Slitting refers to the process of cutting wide materials (such as plastic film, paper, metal foil, etc.) into strips or rolls of the required width along the longitudinal or transverse direction. It is mainly used in industries such as packaging, printing, and electronics, such as slitting plastic film (BOPP, PET, etc.), metallized film, and tape.

[0003] Existing slitting equipment lacks a self-cleaning structure. During the conveying and slitting of wide materials, static electricity is generated due to friction, causing debris and dust generated during slitting to adhere to the slitting material. Therefore, a self-cleaning slitting device is proposed. It uses a structural plate to blow out airflows with positive and negative charges to neutralize the charges on the slitting material, thereby eliminating static electricity and blowing off debris and dust. Summary of the Invention

[0004] In view of the shortcomings of the above-mentioned background technology, the purpose of this utility model is to provide a self-cleaning slitting device that blows out airflow with positive and negative charges through the structural plate to neutralize the charge on the slitting material, thereby eliminating static electricity and blowing off debris and dust.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0006] A self-cleaning slitting device includes a shelf, a slitting assembly on the top of the shelf, and a gantry frame fixed to the top of the shelf by bolts. An internal threaded sleeve is welded to the top of the gantry frame, and a screw rod is sleeved through the internal threaded sleeve. The bottom end of the screw rod inside the gantry frame is connected to a structural frame through a bearing, and a slitting roller is rotatably connected to the structural frame through a bearing.

[0007] A box is installed through the bottom of the shelf, and a cleaning component is fixed to the top of the box by bolts. The cleaning component includes a top plate fixed to the top of the box by bolts, an ion fan is fixed through the top of the top plate by bolts, and structural plates are fixed to the bottom two ends of the top plate by bolts. Pressure rollers are rotatably connected between the structural plates by bearings.

[0008] By adopting the above technical solution, the rotating screw pushes the structural frame and the slitting roller at its bottom to move downward, pressing down the rolled material and slitting it. The ion fan works to remove static electricity from the slitting material and blow away the debris and dust.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: a metal auxiliary roller is rotatably connected inside the gantry frame via bearings, and auxiliary rods are connected to both ends of the top of the structural frame via threaded grooves, with the auxiliary rods penetrating the gantry frame.

[0010] Based on the above scheme and as a preferred option: a discharge port is provided on one side of the box, and a guide plate is fixed to the bottom of the box by bolts.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: a support frame is fixed to one end of the top of the shelf by bolts, a winding roller is rotatably connected inside the support frame by bearings, a geared motor is installed at one end of the support frame by a mounting bracket, and the output shaft on one side of the geared motor is fixedly connected to one end of the winding roller by a connecting sleeve.

[0012] Based on the above scheme and as a preferred option: the top of the shelf away from the support frame is fixed with a placement frame by bolts, and the top two ends of the placement frame are provided with arc-shaped grooves.

[0013] Based on the above scheme and as a preferred embodiment of the above scheme: the shelf is located on the top of one side of the placement rack and is fixed to a frame by bolts, and the two ends inside the frame are rotatably connected to rubber auxiliary rollers by bearings.

[0014] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0015] This invention relates to a self-cleaning slitting device. The rolled material, after being slit by the slitting roller, is pressed and moved within a chamber by the pressure roller. Turning on the ion fan blows out airflow carrying positive and negative charges, neutralizing the charge on the slit material and eliminating static electricity, while simultaneously blowing away debris and dust. The rotating screw in this invention pushes the structural frame downwards via an internal threaded sleeve, thereby pressing the rolled material onto the metal auxiliary roller via the slitting roller, slitting it during the material's movement.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments;

[0021] This embodiment provides a self-cleaning slitting device, including a shelf 1, a slitting assembly 2 on the top of the shelf 1, the slitting assembly 2 including a gantry frame 201 fixed to the top of the shelf 1 by bolts, an internal threaded sleeve 202 welded to the top of the gantry frame 201, a screw 203 passing through the internal threaded sleeve 202, and a structural frame 204 connected to the bottom of the screw 203 inside the gantry frame 201 by a bearing, and a slitting roller 205 rotatably connected inside the structural frame 204 by a bearing;

[0022] A box 3 is installed through the bottom of the shelf 1. A cleaning component 4 is fixed to the top of the box 3 by bolts. The cleaning component 4 includes a top plate 401 fixed to the top of the box 3 by bolts. An ion fan 402 is fixed through the top of the top plate 401 by bolts. Structural plates 403 are fixed to both ends of the bottom of the top plate 401 by bolts. A pressure roller 404 is rotatably connected between the structural plates 403 by bearings.

[0023] During use, rotating the screw 203 pushes the structural frame 204 and its bottom slitting roller 205 downwards, pressing down on the rolled material and slitting it. The ion fan 402 then works to remove static electricity from the slit material and blow away debris and dust. Airflow carrying positive and negative charges is blown out through the structural plate to neutralize the charge on the slit material, achieving the purpose of eliminating static electricity and simultaneously blowing away debris and dust. Figure 1-3 As shown,

[0024] Furthermore, such as Figure 2 As shown, the present invention also includes a metal auxiliary roller 206 rotatably connected inside the gantry frame 201 via bearings, and auxiliary rods 208 connected to the top two ends of the structural frame 204 via threaded grooves, with the auxiliary rods 208 penetrating through the gantry frame 201.

[0025] When in use, the metal auxiliary roller 206 is set up to make it easy for the slitting roller 205 to press the roll material on top of it, which facilitates the slitting of the roll material.

[0026] Furthermore, such as Figure 1As shown, the present invention also includes a discharge port 12 on one side of the box body 3, and a guide plate 13 fixed to the bottom of the box body 3 by bolts.

[0027] During use, the static-free and blown-down debris and dust fall onto the guide plate 13 and are blown out through the discharge port 12.

[0028] Furthermore, such as Figure 1 As shown, this utility model also includes a support frame 5 fixed to one end of the top of the shelf 1 by bolts, a winding roller 6 rotatably connected inside the support frame 5 by bearings, a geared motor 7 mounted on one end of the support frame 5 by a mounting bracket, and an output shaft on one side of the geared motor 7 fixedly connected to one end of the winding roller 6 by a connecting sleeve.

[0029] In use, the geared motor 7 drives the winding roller 6 to rotate, which can pull the rolled material to move.

[0030] Furthermore, such as Figure 1 As shown, the present invention also includes a shelf 10 fixed to the top of the shelf 1 away from the support frame 5 by bolts, and the top two ends of the shelf 10 are provided with arc-shaped grooves 11.

[0031] In use, the placement rack 10 and its top arc groove 11 facilitate the placement of rolled materials that are fitted onto the outside of the shaft.

[0032] Furthermore, such as Figure 1 As shown, the present invention also includes a frame 8 fixed to the top of the shelf 1 on one side of the placement rack 10 by bolts, and rubber auxiliary rollers 9 rotatably connected to both ends of the frame 8 by bearings.

[0033] In use, the rubber auxiliary roller 9 is set to assist in the movement of the rolled material.

[0034] When using this utility model, the operator connects the device to an external power source using a power cord, places the rolled material sleeved on the outside of the shaft on the placement frame 10 through the arc groove 11, pulls out one end of the rolled material and winds it around the outside of the rubber auxiliary roller 9, then through the metal auxiliary roller 206 and the slitting roller 205, passes through the bottom of the pressure roller 404, and finally fixes it to the outside of the winding roller 6. The reduction motor 7 is turned on to drive the winding roller 6 to rotate, thereby pulling the rolled material to move.

[0035] Personnel hold the rocker arm 207 and rotate the screw 203, which pushes the structural frame 204 down through the internal threaded sleeve 202. The slitting roller 205 presses the rolled material onto the metal auxiliary roller 206 and slits it during the movement of the rolled material. The auxiliary rod 208 is set so as not to affect the up and down movement of the structural frame 204 while preventing it from rotating with the screw 203.

[0036] The rolled material after being cut by the slitting roller 205 is pressed by the pressure roller 404 and moves inside the box 3. When the ion fan 402 is turned on, an airflow with positive and negative charges can be blown out to neutralize the charge on the cut material, thereby eliminating static electricity. At the same time, the debris and dust are blown off. The falling debris and dust fall onto the guide plate 13 and flow out from the discharge port 12 for easy collection by personnel.

[0037] By wrapping one end of the rolled material around the outside of the rubber auxiliary roller 9, it can be tightened without affecting the movement of the rolled material.
