Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production equipment, in particular to a filter rod conveying mechanism and a composite filter rod forming machine. Background Art

[0002] The composite filter rod is made of two or more material rods of different materials arranged in a certain length ratio. It can reduce tar and harm, increase flavor and enhance fragrance, and highlight characteristics. It has been widely used in the industry.

[0003] With the popularization and application of composite filter rod products in cigarettes, the structure and composite material types of composite filter rods are becoming increasingly rich, which puts forward higher requirements on the forming process of composite filter rod forming machines. The existing composite technologies at home and abroad are mainly divided into linear composite and roller composite. The main difference between the two different composite methods is how to splice the filter rod segments after cutting. Linear composite refers to the filter rod segments being transported to a straight belt at a time through certain structural components in a regular manner, and then wrapped with forming paper to complete the splicing and forming of multi-segment filter rods. Roller composite draws on the forming method of cigarette making machines, and realizes the splicing and forming of filter rods through the handover and sorting of multiple rollers. However, the equipment process of roller composite technology is relatively complex, and the device occupies a large space, so the market share is low. Linear composite technology has the advantages of simple process and fast replacement of composite structure, and is widely adopted.

[0004] However, in the currently existing linear composite technology, 2-3 circular turntables are used to rotate and connect to realize the transportation of short-segment filter rods and long-segment filter rods. Since the circumferential surface of the circular turntable is arc-shaped, it is easy to cause bending and deformation of the long filter rod segments when conveying longer filter rod segments, which in turn leads to poor quality of the subsequently formed composite filter rods. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a filter rod conveying mechanism and a composite filter rod forming machine, which are used to solve the problem of poor conveying quality of long-segment filter rods by the filter rod conveying mechanism in the prior art.

In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0041] The utility model provides a filter rod conveying mechanism, such as Figure 1 to Figure 2 As shown, the filter rod conveying mechanism includes a base 10, an adapter plate assembly and an arc-shaped slot assembly, wherein the adapter plate assembly is rotatably arranged on the base 10, and the adapter plate assembly includes a feed adapter plate 21, a transition adapter plate 22 and a discharge adapter plate 23, and the outer circumferential surfaces of the feed adapter plate 21, the transition adapter plate 22 and the discharge adapter plate 23 are composed of a plurality of arc segments 201 and a plurality of straight segments 202 arranged alternately in sequence, and the length of the straight segment 202 is greater than the length of the arc segment 201; wherein, a latching tooth 203 is provided at the connection between the arc segment and the straight segment on the feed adapter plate 21, and a latching tooth 203 is also provided at the connection between the arc segment and the straight segment on the transition adapter plate 22, and two adjacent latching teeth 20 3 forms an accommodating groove 204; the arc-shaped slot assembly is fixedly arranged on the base 10, and the arc-shaped slot assembly includes a first arc-shaped slot 31, a second arc-shaped slot 32 and a third arc-shaped slot 33, wherein the first arc-shaped slot 31 is arranged corresponding to the feeding adapter plate 21, and the gap between the first arc-shaped slot 31 and the feeding adapter plate 21 forms a first conveying channel 210, the second arc-shaped slot 32 is arranged corresponding to the transition adapter plate 22, and the gap between the second arc-shaped slot and the transition adapter plate 22 forms a second conveying channel 220, and the third arc-shaped slot 33 is arranged corresponding to the discharge adapter plate 23, and the gap between the third arc-shaped slot 33 and the discharge adapter plate 23 forms a third conveying channel 230.

[0042] When the filter rod conveying mechanism of the utility model is used, Figure 1 As shown, when the long filter rod segments 100 and the short filter rod segments 200 are alternately arranged in sequence and conveyed to the filter rod conveying mechanism of the composite filter rod forming machine through the conveying line, they first enter the first conveying channel 210 formed by the feed adapter plate 21 and the first arc-shaped slot 31, that is, the long filter rod segments 100 are clamped in the receiving groove 204 formed by the latch teeth between the two ends of the straight section by the movement of the latch teeth on the feed adapter plate 21, and rotate together with the feed adapter plate 21, and the short filter rod segments 200 are clamped in the receiving groove formed by the latch teeth between the two ends of the arc section by the movement of the latch teeth on the feed adapter plate 21, and rotate together with the feed adapter plate 21. The first arc-shaped slot 31 is used to ensure the stability of the long filter rod segments 100 and the short filter rod segments 200 in conveying in the first conveying channel 210. When the long filter rod segments / short filter rods When the segment is rotated by the feeding adapter plate 21 to the intersection position with the transition adapter plate 22, the long filter rod segment 100 / short filter rod segment 200 is transferred to the transition adapter plate 22 at the intersection. Similarly, the long filter rod segment 100 is on the straight section of the transition adapter plate 22, and the short filter rod segment 200 is on the arc section of the transition adapter plate 22 and rotates together with the transition adapter plate 22. When the long filter rod segment / short filter rod segment follows the transition adapter plate 22 to rotate to the intersection position of the transition adapter plate 22 and the discharge adapter plate 23, the long filter rod segment 100 / short filter rod segment 200 is transferred to the third conveying channel 230 formed by the gap between the discharge adapter plate 23 and the third arc-shaped slot 33, and the long filter rod segment / short filter rod segment is output from the third conveying channel 230 through the rotation of the discharge adapter plate 23. Compared with the prior art, the filter rod conveying mechanism of the utility model arranges the adapter plate to be non-circular, that is, arranges the outer peripheral surface of the adapter plate to be composed of straight sections and arc sections. When the filter rod is conveyed, the straight section on the adapter plate can adapt to the longer straight filter rod, thereby reducing the extrusion and bending deformation of the long filter rod caused by the operation of the adapter plate, thereby improving the stability and quality of the conveying of the long filter rod segments, and thus improving the quality of the formed composite filter rod.

[0043] Specifically, in this embodiment, the height of the latch teeth 203 can be slightly smaller than the diameter of the filter rod. Preferably, the height of the latch teeth 203 can be 0.5 mm to 2 mm smaller than the diameter of the filter rod.

[0044] Preferably, in this embodiment, the arc segment 201 can be 1mm-8mm larger than the short filter rod segment, and the length of the straight segment 202 can be 1mm-10mm larger than the long filter rod segment. Specifically, in some embodiments, the length of the arc segment 201 can be 9mm-38mm, and the length of the straight segment can be 31mm-80mm.

[0045] Further, such as Figure 1 and Figure 4 As shown, in the present embodiment, an air supply disc 40 is provided at the center of the discharge adapter disc 23, and the discharge adapter disc 23 can rotate relative to the air supply disc 40, that is, the air supply disc 40 does not rotate along with the rotation of the discharge adapter disc 23, and a ventilation area 401 is provided on the air supply disc 40, and the ventilation area 401 is arranged opposite to the third arc-shaped slot 33, and accordingly, a plurality of ventilation pipes 231 are evenly spaced on the discharge adapter disc 23 along the circumferential direction of the discharge adapter disc 23, and the ventilation pipe 231 extends along the radial direction of the discharge adapter disc 23, and a positioning pressure head 232 is slidably provided in the ventilation pipe 231. Through this structural design, during operation, the air supply disc is connected to an external high-pressure gas source. When the vent pipe 231 on the discharging adapter disc 23 rotates to the position of the vent area 401 on the air supply disc 40, the high-pressure gas from the vent area 401 enters the vent pipe 231, thereby blowing out the positioning pressure head 232 in the vent pipe 231. The positioning pressure head 232 will protrude from one end of the vent pipe 231 and press on the filter rod segment, thereby applying a certain pressure to the filter rod segment, thereby preventing the filter rod segment from deviating during transportation in the third transportation channel 230, and improving the stability of the filter rod transportation. When the vent pipe 231 on the discharging adapter disc 23 rotates away from the vent area 401, the positioning pressure head 232 in the vent pipe 231 retracts into the vent pipe 231.

[0046] Specifically, Figure 4 As shown, in this embodiment, there are seven ventilation pipes 231, and the ventilation pipes 231 intersect with the arc segments 201 on the discharge transfer plate 23 in the radial direction of the discharge transfer plate 23. Therefore, when the short filter rod segment is transported in the third transport channel 230, the positioning pressure head 232 in the ventilation pipe will apply a certain pressure to the short filter rod segment, thereby improving the transportation stability of the short filter rod segment.

[0047] Another aspect of the present invention further provides a composite filter rod forming machine, which comprises the above-mentioned filter rod conveying mechanism.

[0048] The beneficial effects of the composite filter rod forming machine of the present invention are the same as those of the filter rod conveying mechanism described above, so they will not be described in detail here.

[0049] In summary, the filter rod conveying mechanism and composite filter rod forming machine of the utility model can meet the conveying of long filter rod segments, reduce the bending deformation phenomenon of the filter rod segments during conveying in the transfer plate, and provide an intermittent positioning pressure head to prevent the filter rods from being misplaced and offset during conveying, thereby improving the stability of the filter rod conveying. Therefore, the utility model effectively overcomes various shortcomings of the prior art and has a high industrial utilization value.

[0050] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
