Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a wrinkle-proof film and paper dual-purpose slitting device. Background Art

[0002] Film and paper dual-purpose slitting device is a slitting machine. A slitting machine is a mechanical device that cuts wide paper, mica tape or film into multiple narrow materials. It is commonly used in papermaking machinery, wire and cable mica tape and printing and packaging machinery. The slitting machine is mainly used for: non-woven fabrics; mica tape, paper, insulation materials and various film materials, especially suitable for the slitting of narrow tapes (non-woven fabrics, paper, insulation materials, mica tape, film, etc.);

[0003] The dual-purpose slitting machine is a common mechanical equipment, which is mainly used to cut bulk materials or products into required sizes and shapes; it is suitable for various industries, such as food, pharmaceuticals, chemicals, plastics, etc. Common slitting machines include paper slitting machines, plastic film slitting machines, cloth slitting machines, etc., which can cut bulk materials or products into required sizes and shapes. Slitting machines can cut bulk materials or products into required sizes and shapes;

[0004] When conventional equipment is in use, the operator loads the raw materials or products to be cut onto the loading roller of the slitting machine, then sets the size and shape to be cut, starts the slitting machine, and adjusts the loading and unloading shafts to allow the raw materials or products to enter the cutting area. Then the blade of the slitting machine starts to operate, cutting the raw materials or products into the required size and shape. Finally, the cut raw materials or products run along the unloading shaft to the unloading area to complete the slitting process.

[0005] For example, the utility model with application number 202123022626.7 discloses a winding device for a film slitting machine that prevents wrinkles. The winding device for a film slitting machine that prevents wrinkles is equipped with a fixing strip. When the film is being wound on the winding roller, the fixing strip can fix the film to prevent the film from slipping. By installing a smoothing plate, the smoothing plate can smooth the film attached to the outer end of the connecting arm to prevent wrinkles in the film, which affects subsequent film lamination and improves work efficiency. However, similar to the slitting machine winding device in the above-mentioned document, its structure lacks tension adjustment for smoothing the film and paper, so that even when the smoothing plate is in operation, wrinkles may occur because the film and paper being transported are not stretched as tight as possible, resulting in a relatively limited smoothing effect.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and an anti-wrinkle film and paper dual-purpose slitting device is proposed. Utility Model Content

[0007] The utility model aims to provide a wrinkle-proof film and paper dual-purpose slitting device to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-wrinkle film and paper dual-purpose slitting device, comprising a device frame and a tensioning assembly, the left and right sides of the device frame are connected with the tensioning assembly, and an adjusting roller group is horizontally installed at the bottom of the device frame, and a feeding assembly is installed at one end of the adjusting roller group, and a slitting table is installed at the end of the device frame away from the feeding assembly, and a cutting knife assembly is horizontally installed just above the slitting table, and hydraulic push rods are vertically installed at the left and right ends of the top of the cutting knife assembly, and the tensioning assembly comprises a stabilizing frame, a fixing frame, a guide rod and a tensioning roller, and the left and right sides of the stabilizing frame are vertically installed with fixing frames, and the side elevations of the fixing frame are vertically installed with guide rods, and the surface of the guide rod is slidably installed with tensioning rollers.

[0009] Furthermore, the guide rod and the tensioning roller are connected in an "H"-shaped structure, and the stabilizing frame and the device frame are connected by welding.

[0010] Furthermore, the adjustment roller group includes a support frame, an adjustment rod, a first material guide roller and a second material guide roller. The adjustment rod is horizontally installed on the left and right sides of the support frame, and the first material guide roller is slidably installed on the surface of one end of the adjustment rod, and the second material guide roller is slidably installed on the end of the adjustment rod away from the first material guide roller.

[0011] Furthermore, the second material guide roller and the first material guide roller have the same structure, and the first material guide roller and the second material guide roller are respectively arranged on the front and rear sides of the tensioning component.

[0012] Furthermore, the feeding assembly includes a feeding roller, a reeling and unwinding motor and a pneumatic push rod. The reeling and unwinding motors are installed at the left and right ends of the feeding roller, and the pneumatic push rod is vertically installed on the top of the reeling and unwinding motor.

[0013] Furthermore, the top of the pneumatic push rod is connected to the device frame, and the feed roller is used to drive the reeling and unreeling motor and the pneumatic push rod to rise and fall in the vertical direction.

[0014] Furthermore, the cutter assembly includes a mounting frame, a cutter, a fixed spring bolt and a slider, the mounting frame has the cutter inserted inside, a fixed spring bolt runs horizontally between the cutter and the mounting frame, and sliders are installed on the left and right sides of the mounting frame.

[0015] Furthermore, one end of the fixed spring bolt horizontally penetrates the mounting frame and the cutter at the same time, and the sliding block is slidably connected to the device frame.

[0016] The utility model provides a wrinkle-proof film and paper dual-purpose slitting device, which has the following beneficial effects:

[0017] 1. The utility model allows one end of the film and paper to extend from the feed roller, pass over the second guide roller 30, and then pass obliquely from top to bottom to the bottom of the tensioning roller, and then pass obliquely from bottom to top to the top of the second guide roller until it passes horizontally through the surface of the slitting table. During the entire film and paper conveying process, the tensioning roller is used to move vertically up and down along the surface of the first guide roller, and the first guide roller and the second guide roller can move horizontally along the surface of the adjustment rod. The movable adjustment of the above structure can effectively provide tension adjustment for the film and paper, and can avoid unnecessary wrinkles when the film and paper are conveyed and cut as much as possible, which will cause conveying and cutting problems.

[0018] 2. The utility model forms a quick-installation structure by vertically inserting the cutter from the bottom of the mounting frame into the interior of the mounting frame, and then horizontally penetrating the mounting frame and the cutter with a horizontally installed fixing spring bolt. By using this method, the structure can be effectively disassembled and maintained, so that the staff can flexibly and conveniently replace the cutter quickly. In addition, by sliding blocks on both sides of the mounting frame and slidingly installing it on one side of the device frame, the entire cutter assembly maintains the maximum degree of structural stability during the vertical up and down reciprocating push generated by the extension and contraction of the hydraulic push rod structure, thereby ensuring stable cutting of film and paper, avoiding the occurrence of "continuous knife" and realizing dual-purpose slitting of film and paper.
