Description

Technical Field

[0001] This utility model relates to the field of food packaging bag processing technology, specifically to a slitting and bag-making equipment for food packaging bag processing. Background Technology

[0002] In the automated production of food packaging bags, slitting and bag making is a critical final process, and its precision and efficiency directly affect the quality of the finished product and the production cost.

[0003] Traditional equipment often uses cutters or disc cutter sets with fixed spacing. The continuous packaging bags are fed into the cutting area by traction rollers to complete the cutting. The cutter spacing is fixed. When producing packaging bags of different widths or lengths, it is necessary to manually replace the entire set of cutters or adjust the mechanical limit, which is difficult to meet the needs of multi-specification small-batch production.

[0004] Therefore, a slitting and bag-making equipment for food packaging bag processing is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a slitting and bag-making equipment for food packaging bag processing in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A slitting and bag-making device for food packaging bags includes a base, a U-shaped frame and a traction component on the base. The traction component is used to output the edge material of the food packaging bags for traction and movement. A pressing component is provided on the U-shaped frame. A first motor is fixedly installed on one side wall of the U-shaped frame, and the output end of the first motor is fixedly connected to a cutting component for cutting the edges of the food packaging bags. A slitting component is provided between the U-shaped frame and the traction component for forming and slitting the food packaging bags.

[0008] Furthermore, the edge-cutting assembly includes a shaped shaft rotatably inserted into the two side walls of the U-shaped frame, the output end of the first motor is fixedly connected to one end of the shaped shaft, wherein the surface of the shaped shaft is provided with a plurality of sets of equidistant first threaded holes, and a collar is slidably sleeved on the surface of the shaped shaft, and a second threaded hole is provided on the surface of the collar, and a blade is fixedly sleeved on the surface of the second threaded hole, and bolts are threaded into the second threaded hole and one of the sets of first threaded holes for fixing the position of the collar and the blade after adjustment.

[0009] Furthermore, the clamping assembly includes a first hydraulic rod fixedly installed on the top surface of the U-shaped frame. The telescopic end of the first hydraulic rod passes through the U-shaped frame and is fixedly connected to a mounting frame. Pressure rollers are rotatably inserted into the two side walls of the mounting frame, and the pressure rollers are located above the blade.

[0010] Furthermore, the slitting assembly includes a frame fixedly installed between the U-shaped frame and the traction assembly. A second hydraulic rod is fixedly installed on the top surface of the frame. The telescopic part of the second hydraulic rod passes through the frame and is fixedly connected to a cutter disc. A cutter is fixedly installed on the bottom surface of the cutter disc. A lower slitting seat is fixedly installed on the top surface of the base, and a cutting groove is formed on the top surface of the lower slitting seat.

[0011] Furthermore, the traction assembly includes a traction frame fixedly mounted on the base, two sets of traction rollers rotatably mounted on the two side walls of the traction frame, and gears fixedly sleeved at the ends of the two sets of traction rollers, with the two sets of gears meshing with each other. A second motor is fixedly mounted on one side wall of the traction frame, and the output end of the second motor is fixedly connected to the end of one of the traction frames.

[0012] Furthermore, the cutting tool and the cutting groove are arranged in a corresponding manner, and the cutting tool and the cutting groove are engaged to cut the food packaging bag into shape.

[0013] The beneficial effects of this utility model are as follows:

[0014] The food packaging bag is pulled to move at a constant speed by the traction component. The edge cutting component on the U-shaped frame is driven to rotate by the first motor to continuously cut the edge of the packaging bag and remove excess material. The packaging bag is pressed by the pressing component during the edge cutting. The slitting component is located downstream of the edge cutting component and cuts the continuous packaging bag into individual bags.

[0015] The collar is fixed to the first threaded hole at different positions by bolts through the second threaded hole on its surface. The cutting range of the blade can be changed by the blade being located on the outer edge of the collar and by the axial position of the collar on the irregular shaft, thereby adapting to packaging bags of different widths.

Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use.

Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1 to 4 As shown, a slitting and bag-making device for food packaging bags includes a base 1, on which a U-shaped frame 2 and a traction component 7 are mounted. The traction component 7 is used to output the edge material of the food packaging bags for traction and movement of the food packaging bags. Figure 1 and Figure 2 As shown, specifically, the traction assembly 7 includes a traction frame 701 fixedly mounted on the base 1. Two sets of traction rollers 702 are rotatably mounted on both sides of the traction frame 701. Gears 703 are fixedly sleeved at the ends of both sets of traction rollers 702. The two sets of gears 703 mesh with each other. A second motor 704 is fixedly mounted on one side of the traction frame 701. The output end of the second motor 704 is fixedly connected to the end of one set of traction frames 701.

[0026] More specifically, two sets of traction rollers 702 are installed on both sides of the traction frame 701. They rotate in opposite directions through the meshing of gears 703. One set of traction rollers 702 is driven to rotate by a second motor 704, while the other traction roller 702 rotates in opposite directions synchronously through gears 703, forming a "clamping traction". This allows the food packaging bag to be processed to move continuously through the edge waste, and continuous cutting can be achieved through the cutting component 6.

[0027] The U-shaped frame 2 is equipped with a clamping component 3; such as Figure 1 and Figure 2 As shown, specifically, the clamping assembly 3 includes a first hydraulic rod 301 fixedly installed on the top surface of the U-shaped frame 2. The telescopic end of the first hydraulic rod 301 passes through the U-shaped frame 2 and is fixedly connected to a mounting frame 302. Pressure rollers 303 are rotatably inserted into the two side walls of the mounting frame 302, and the pressure rollers 303 are located above the blade 505.

[0028] More specifically, the first hydraulic rod 301 drives the mounting frame 302 to rise and fall, and the pressure roller 303 is inserted into the two side walls of the mounting frame 302 by rotation, which can adapt to the thickness of the packaging bag. The pressure roller 303 and the blade 505 form a "press-cut" linkage, and the packaging bag is pressed by the pressure roller 303 while being cut by the blade 505, thus avoiding material shrinkage.

[0029] A first motor 4 is fixedly installed on one side wall of the U-shaped frame 2, and a cutting edge assembly 5 is fixedly connected to the output end of the first motor 4 for cutting the edges of food packaging bags; for example Figure 1 , Figure 2 and Figure 3 As shown, specifically, the edge-cutting assembly 5 includes a shaped shaft 501 rotatably inserted into the two side walls of the U-shaped frame 2. The output end of the first motor 4 is fixedly connected to one end of the shaped shaft 501. The surface of the shaped shaft 501 is provided with several sets of equidistant first threaded holes 502. A collar 503 is slidably sleeved on the surface of the shaped shaft 501. A second threaded hole 504 is provided on the surface of the collar 503. A blade 505 is fixedly sleeved on the surface of the second threaded hole 504. Bolts 506 are threadedly inserted into the second threaded hole 504 and one set of first threaded holes 502 to fix the position of the collar 503 and the blade 505 after adjustment.

[0030] More specifically, the irregular shaft 501 has multiple sets of first threaded holes 502 on its surface. The collar 503 is fixed to the first threaded holes 502 at different positions by the second threaded holes 504 on its surface and the bolts 506. The blade 505 is located on the outer edge of the collar 503. By changing the axial position of the collar 503 on the irregular shaft 501, the cutting range of the blade 505 can be changed, thereby adapting to packaging bags of different widths.

[0031] A cutting component 6 is provided between the U-shaped frame 2 and the traction component 7 for forming and cutting food packaging bags; such as Figure 1 , Figure 2 and Figure 4 As shown, specifically, the slitting assembly 6 includes a frame 603 fixedly installed between the U-shaped frame 2 and the traction assembly 7. A second hydraulic rod 604 is fixedly installed on the top surface of the frame 603. The telescopic part of the second hydraulic rod 604 passes through the frame 603 and is fixedly connected to the cutter disc 605. A cutter 606 is fixedly installed on the bottom surface of the cutter disc 605. A lower slitting seat 601 is fixedly installed on the top surface of the base 1, and a cutting groove 602 is opened on the top surface of the lower slitting seat 601.

[0032] More specifically, the second hydraulic rod 604 drives the cutter disc 605 and the cutter 606 to press down vertically, so that the cutter 606 engages with the cutting groove 602 of the lower cutting seat 601 to form a "guillotine" cutting. The gap between the blade of the cutter 606 and the cutting groove 602 is ≤0.05mm, ensuring that the cut is flat and burr-free. The formed food packaging bag is discharged through the cutting groove 602.

[0033] like Figure 4 As shown, in some practical applications, the cutting tool 606 and the cutting groove 602 are arranged in a corresponding manner, and the cutting tool 606 and the cutting groove 602 are engaged to cut the food packaging bag into shape.

[0034] More specifically, the cutting edge shape of the tool 606 is perfectly matched with the groove of the cutting groove 602. The downward stroke during slitting is controlled by the second hydraulic rod 604. When engaged, the tool 606 cuts into the cutting groove 602 to a depth of 2-3mm, ensuring "full thickness cutting" without damaging the lower slitting seat 601.

[0035] In summary: the food packaging bag is pulled to move at a constant speed by the traction component 7, and the edge cutting component 5 on the U-shaped frame 2 is driven to rotate by the first motor 4 to continuously cut the edge of the packaging bag and remove excess edge material. The packaging bag is pressed by the pressing component 3 during edge cutting. The slitting component 6 is located downstream of the edge cutting component 5 and cuts the continuous packaging bag into independent bags.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
