Description

Technical Field

[0001] The utility model relates to the technical field of cigarette filter rod production equipment, in particular to a multi-specification filter rod equal-section cutting machine. Background Art

[0002] During the production of cigarette filter rods, the dryness and humidity of the filter rods, internal defects such as fiber cavities, and the chemical composition of each section are important quality inspection links in the filter rod production process. These defects that affect the quality of cigarette filter rods are difficult to find during the production process. The only way to ensure the quality of the product is to sample the finished cigarette filter rods during the production process and cut and inspect them.

[0003] The traditional technology is that after the material is loaded through the hopper, the unloading wheel drives the cigarette filter rod to move towards the slitting blade under the drive of the motor. The disturbance wheel is driven by the disturbance motor to make the material unloading smooth and not stuck. The slitting motor drives the slitting blade to complete the slitting of the cigarette filter rod driven by the unloading wheel during the rotational motion. The disturbance motor then drives the conveyor belt through gear transmission to complete the discharge.

[0004] In this traditional technology, the feeding wheel is not compatible with cigarette filter rods of various specifications, and the overall structure is complicated to disassemble and assemble when replacing the feeding wheel; a single set of blades is not compatible with the equal-segment cutting of cigarette filter rods of different lengths, and the overall structure is complicated to disassemble and assemble when replacing different blade groups, and the safety of personnel during operation cannot be guaranteed; during the discharging process, the materials are fed side by side, which is prone to jamming, and may also occur internally, making it difficult to handle faults. This type of cigarette filter rod slitting machine can refer to the patent application number 2014207419327;

[0005] The traditional cigarette filter rod cutting machine has the following disadvantages due to the design of the mechanism action implementation method:

[0006] 1. The feed wheel is not compatible with cigarette filter rods of various specifications. The feed wheel of traditional technology is a dedicated device for cigarette filter rods of a single specification. If you want to achieve compatibility with cigarette filter rods of different specifications by replacing different feed wheels, the replacement process is complicated due to the structure, which affects production efficiency.

[0007] 2. A single set of blades cannot be compatible with the equal-slicing of cigarette filter rods of different lengths. The traditional technology is to cut the filter rods with a single set of blades, so the length of the cigarette filter rod after each cut is a fixed value. Among the different length specifications of cigarette filter rods, a fixed cutting length cannot meet the needs. By replacing the cutter group with different cutting lengths to meet the cutting of cigarette filter rods of different lengths, the replacement process is complicated, and a set of knives consists of multiple blades, the replacement safety is low, and the production efficiency is affected.

[0008] 3. During the discharging process, the materials are discharged side by side, which is prone to jamming. It may also occur internally and is difficult to handle. After being cut by the cutter, the cigarette filter rods are divided into multiple small lengths. The cut cigarette filter rods are transferred to the conveyor belt by the discharge wheel, and then transferred to the discharge chute via the conveyor belt. In summary, the cigarette filter rods have a high degree of freedom on the conveyor belt. At the joint of the conveyor belt and the discharge bevel, the cut filter rods are prone to jamming, accumulation, and squeezing. Problems such as jamming and accumulation are prone to occur in the discharge chute, which makes cleaning difficult and affects production efficiency.

[0009] 4. The filter rod after cutting cannot be automatically divided into multiple equal parts, and is in a completely disordered state. The overall equipment structure does not have an automatic equal division mechanism after cutting, and it is impossible to determine that each equal part corresponds to a different length segment of the filter rod, and it is impossible to accurately confirm the chemical and physical properties of different length segments of the filter rod, which affects the accuracy of the test.

[0010] Therefore, it is necessary to develop a multi-specification filter rod equal-section slitting machine to solve the above problems. Utility Model Content

[0024] Furthermore, the multi-specification filter rod equal-section slitting machine also includes a material receiving box, which is placed below the variable feeding wheel.

[0025] The beneficial effects of the utility model are:

[0026] A variable loading wheel is used. Without changing the unloading wheel, the filter rods of various specifications can be compatible by changing the moving wheel, thereby improving production efficiency.

[0027] By turning the hand wheel, different vertically parallel knife groups are accurately changed under the drive of the knife holder to cooperate with the first motor to achieve different cutting specifications; there is no need to manually change the cutting knife group, which simplifies the use process, reduces the requirements for different cutting lengths of compatible cigarette filter rods of various specifications, improves safety, and improves production efficiency;

[0047] like Figure 1-2 As shown in 6, a multi-specification filter rod segment cutting machine comprises:

[0048] The slitting knife group 3 includes a knife frame 31, a first knife group 32 and a second knife group 34 with different cutting intervals, a first rotating shaft 36, and a second rotating shaft 37. The first knife group 32 is installed on the first rotating shaft 36, and the second knife group 34 is installed on the second rotating shaft 37.

[0058] During operation, the grooves of the moving plate 106 and the grooves of the fixed plate 107 of the same width are selected to be located in a row for loading filter rods. When it is necessary to adjust and adapt to the loading of filter rods of other diameters, the bolts 105 are loosened, and the moving wheel 103 is rotated until the grooves of the moving plate 106 and the grooves of the fixed plate 107 of the required width are placed in a row, and then the bolts 105 are tightened.

[0062] When performing filter rod cutting, first put the filter rod in the hopper 4, and then carry it upward under the action of the variable feeding wheel 10, and the filter rod enters between the partition 12 and the variable feeding wheel 10. The multiple blades of the knife group pass through the multiple knife grooves 13 respectively and act on the filter rod fed by the variable feeding wheel 10. The filter rod is cut into multiple sections, and the variable feeding wheel 10 continues to rotate. The filter rod cut at the lower position falls into the receiving box 5.
