Description

Technical Field

[0001] This invention relates to the field of tobacco manufacturing equipment technology, and specifically to a filter rod cutting and conveying device. Background Technology

[0002] In the field of tobacco manufacturing equipment technology, composite filter rods have become an important consumable in cigarette production due to their multiple functions. They are formed by combining two or more base rods, and there are many types. Some products require the addition of functional ingredients such as flavorings and fragrances to the base rods to optimize the taste of cigarettes.

[0003] Existing filter rod cutting and conveying devices face numerous technical bottlenecks when processing composite filter rods containing special components: Firstly, the fragrances and flavorings in the filter rods can easily form sticky substances during the slitting process, causing the filter rods to adhere to the inner wall of the circumferential grooves of the blades and slitting hubs. This not only causes quality defects such as burrs, stains, and insufficient flatness at the slitting cut, but also directly reduces the slitting efficiency. Secondly, the existing conveying structure design is not reasonable enough. After the filter rods are separated from the cutting hub, they are prone to jamming and accumulation in the conveying channel, making it impossible to achieve continuous and stable conveying. Third, the persistent adhesion of residual adhesive requires frequent machine shutdowns for cleaning, which not only increases labor maintenance costs but also seriously affects production continuity. Fourth, the existing equipment has poor adaptability and is difficult to match the cutting and conveying requirements of composite filter rods of different specifications. In addition, it lacks an effective filter rod separation mechanism, which leads to disordered feeding in downstream processes and further affects the overall production efficiency.

[0004] The aforementioned problems have hampered the quality stability and automation level of composite filter rod production, necessitating a slitting and conveying device that can solve issues such as residual adhesive adhesion and unstable conveying. Summary of the Invention

[0005] The purpose of this invention is to provide a filter rod cutting and conveying device, which aims to solve the aforementioned technical problems existing in the prior art. To achieve the above objectives, the present invention adopts the following technical solution: A filter rod cutting and conveying device is installed at the end of the filter rod hopper, including a support frame. A vertical mounting plate is provided on the top of the front of the support frame, an upper mounting plate is provided at the bottom of the vertical mounting plate in a horizontal direction, and a lower mounting plate is provided below the upper mounting plate and parallel to it. A slitting hub assembly connected to the end of the hopper is fixedly installed at the center of the bottom of the vertical mounting plate. A hub negative pressure assembly and a de-adhesive assembly are arranged sequentially from top to bottom on the surface of the vertical mounting plate and on the right side of the slitting hub assembly. The slitting hub assembly provides a negative pressure source through the hub negative pressure assembly to make the filter rods be adsorbed on its circumferential surface, and removes the residual adhesive generated during slitting through the de-adhesive assembly, thereby realizing stable slitting and conveying of the filter rods. A cutter assembly is provided on the left side of the splitting hub assembly. The cutter assembly is fixedly installed between the vertical mounting plate and the upper mounting plate. A stop bar assembly is engaged between the cutter assembly and the splitting hub assembly. The stop bar assembly is fixedly installed to the vertical mounting plate. The splitting hub assembly uses the stop bar assembly to make the filter rod move closely against the circumferential surface. When the filter rod rotates to the cutter assembly, it is precisely cut. Below the slitting hub assembly is a bar output assembly, which includes a lateral adjustment assembly fixedly mounted on the top surface of the lower mounting plate. A lifting adjustment assembly is fixedly mounted on the top surface of the moving end of the lateral adjustment assembly. A transmission chain assembly is provided at the lifting end of the lifting adjustment assembly. Multiple chain hooks are evenly arranged around the transmission chain assembly, moving in a circular motion. These chain hooks extend upwards from the upper mounting plate and are positioned between the upper left guide channel and the right guide channel fixedly mounted on the top surface of the upper mounting plate. The gap between the upper left guide channel and the right guide channel forms a filter rod channel groove, located directly below the slitting hub assembly. The filter rods are hooked out of the slitting hub assembly by the chain hooks and fed through the filter rod channel groove to the bar separation assembly for individual separation before entering the smoke-dispensing assembly. Both the bar separation assembly and the smoke-dispensing assembly are fixedly mounted on the top surface of the upper mounting plate and positioned in front of the slitting hub assembly. The smoke-dispensing assembly conveys the filter rods downstream.

[0006] Furthermore, the split hub assembly includes a servo motor, which is fixed to the back of the vertical mounting plate via a motor mounting plate. A hub core is fixedly mounted at the front end of the output shaft of the servo motor, and at least two split hub wheels are fixedly mounted equidistantly along the axial direction on the surface of the hub core. The circumferential surface of the slitting hub is uniformly provided with multiple circumferential grooves, and multiple negative pressure holes are equidistantly provided along the length of the circumferential grooves. The slitting hub provides negative pressure to each of the negative pressure holes through the hub negative pressure assembly, so that the filter rod is adsorbed into the circumferential groove.

[0007] Furthermore, the adhesive removal assembly includes a support block, which is fixed to the surface of the vertical mounting plate with adjustable left and right positions. A transparent cover is fixedly installed on the other side of the support block. A lead screw slide assembly is fixedly installed on the top surface of the inner wall of the transparent cover. A connecting block is fixedly installed on the sliding surface of the lead screw slide assembly. Scraper blades are fixedly installed at both ends of the connecting block near the slitting hub. The lead screw of the lead screw slide assembly is provided with an adjustment handle. The scraper blades extend out of the transparent cover by turning the adjustment handle and extend into the cutting seam between two adjacent slitting hubs to remove residual adhesive generated during slitting.

[0008] Furthermore, the cutting assembly includes a blade, and blade cleaning assemblies are provided at the bottom of the left and right sides of the blade. The two sets of blade cleaning assemblies remove residual adhesive from the surface of the blade.

[0009] Furthermore, the transmission chain assembly consists of a drive wheel, a driven wheel, a tension wheel, and a chain that rotatably connects them. The drive wheel is fixedly installed on the drive shaft of the drive assembly, and a plurality of chain hooks are evenly fixedly installed on the surface of the chain.

[0010] Furthermore, the bar separation assembly includes a fixed plate and a cylinder lifting assembly. The fixed plate and the cylinder lifting assembly are respectively fixedly installed on the top and bottom sides of the upper mounting plate. A rotary motor is fixedly installed on one side of the fixed plate and the lifting end of the cylinder lifting assembly. An upper ejector wheel and a lower ejector wheel are respectively fixedly installed on the output shafts of the two rotary motors. The upper ejector wheel and the lower ejector wheel are driven to rotate in opposite directions by the two rotary motors, and the gap between them is located in the filter bar channel groove.

[0011] Furthermore, the smoke-dispensing assembly includes a conveying motor, which is fixedly mounted on the bottom surface of the upper mounting plate. The output shaft of the conveying motor passes through the top surface of the upper mounting plate and is fixedly mounted in the center of the dial. The circumferential surface of the dial is evenly provided with multiple dial teeth, which are driven by the rotation of the conveying motor to push the filter rod for conveying.

[0012] The beneficial effects of this invention are: Significantly improved slitting quality and efficiency: The scraper blade of the adhesive removal component extends into the cutting seam of the slitting hub, and the blade cleaning component of the cutter assembly simultaneously cleans the residual adhesive on the blade surface. The dual cleaning structure completely solves the problem of adhesion of fragrance and flavoring filter rods, avoids defects such as burrs and stains on the cut, greatly improves slitting accuracy and product qualification rate, and reduces slitting resistance caused by residual adhesive, thereby improving slitting efficiency.

[0013] Enhanced conveying stability and continuity: The negative pressure hole adsorption design of the slitting hub wheel, combined with the baffle assembly, ensures that the filter rods move closely to the circumferential surface during the slitting process, avoiding deviation; the combination of a dedicated material guide channel and a chain hook output structure enables the filter rods to smoothly detach from the circumferential groove and be conveyed in a directional manner, completely eliminating jamming and accumulation; the bidirectional rotating ejector design of the rod separation assembly accurately separates the filter rods one by one, providing orderly feeding assurance for downstream processes.

[0014] Reduced maintenance costs and manual intervention: The automated residual adhesive cleaning structure reduces the frequency of traditional manual downtime for adhesive scraping, thus reducing the intensity of manual maintenance and equipment usage; each component adopts a modular design and adjustable structure (such as the screw slide adjustment of the adhesive removal component and the horizontal and vertical adjustment of the bar output component), which facilitates installation, commissioning and subsequent maintenance, further reducing overall maintenance costs.

[0015] Expanded equipment adaptability and versatility: The device adapts to composite filter rods of different specifications through multi-dimensional adjustment structure, and has good adaptability, especially for filter rods containing ingredients that are easy to adhere to, such as flavorings and fragrances; the independent mounting plate design of the support frame and the collaborative working mechanism of each component make it flexibly integrated into the existing tobacco production line without large-scale modification, and it has strong versatility.

[0016] Production economy and automation level optimization: Improved slitting accuracy and reduced conveying losses reduce filter rod material waste and improve production economy; the fully automated connection of the entire process from slitting, degumming, conveying to separation and feeding reduces manual intervention, meets the automated production needs of the modern tobacco industry, and helps upgrade the overall automation level of the production line.

[0019] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0020] Example: like Figure 1-8 As shown, this embodiment provides a filter rod cutting and conveying device, which is set at the end of the filter rod hopper. It includes a support frame 1, a vertical mounting plate 101 is set on the top of the front of the support frame 1, an upper mounting plate 102 is set on the bottom of the vertical mounting plate 101 in the horizontal direction, and a lower mounting plate 103 is set below the upper mounting plate 102 and parallel to it. A slitting hub assembly 2 connected to the end of the hopper is fixedly installed at the bottom center of the vertical mounting plate 101. A hub negative pressure assembly 3 and a de-adhesive assembly 4 are arranged sequentially from top to bottom on the surface of the vertical mounting plate 101 and on the right side of the slitting hub assembly 2. The slitting hub assembly 2 provides a negative pressure source through the hub negative pressure assembly 3 to make the filter rods be adsorbed on its circumferential surface, and removes the residual adhesive generated by slitting through the de-adhesive assembly 4, so as to realize the stable slitting and conveying of the filter rods. A cutter assembly 7 is provided on the left side of the slitting hub assembly 2. The cutter assembly 7 is fixedly installed between the vertical mounting plate 101 and the upper mounting plate 102. A stop bar assembly 6 is clamped between the cutter assembly 7 and the slitting hub assembly 2. The stop bar assembly 6 is fixedly installed with the vertical mounting plate 101. The slitting hub assembly 2 uses the stop bar assembly 6 to make the filter rod move closely against the circumferential surface. When the filter rod rotates to the cutter assembly 7, it is precisely cut. Below the slitting hub assembly 2, a bar stock output assembly 5 is provided. The bar stock output assembly 5 includes a lateral adjustment assembly 505, which is fixedly installed on the top surface of the lower mounting plate 103. A lifting adjustment assembly 504 is fixedly installed on the top surface of the moving end of the lateral adjustment assembly 505. A transmission chain assembly is provided on the lifting end of the lifting adjustment assembly 504. Multiple chain hooks 502 are evenly arranged around the transmission chain assembly, and they move in a circular motion. The chain hooks 502 extend upward from the upper mounting plate 102 and are fixedly installed on the upper mounting plate 103. Between the upper left guide channel 11 and the right guide channel 10 on the top surface, a filter rod channel groove is formed. The filter rod channel groove is located directly below the slitting hub assembly 2. The filter rod is hooked out from the slitting hub assembly 2 by the chain hook 502 and sent to the rod separation assembly 8 through the filter rod channel groove to achieve separation one by one and enter the smoke-dispensing assembly 9. The rod separation assembly 8 and the smoke-dispensing assembly 9 are both fixedly installed on the top surface of the upper mounting plate 102 and are in front of the slitting hub assembly 2. The smoke-dispensing assembly 9 conveys the filter rod downstream.

[0021] The split hub assembly 2 includes a servo motor 205, which is fixed to the back of the vertical mounting plate 101 by a motor mounting plate. A hub core 202 is fixedly mounted on the front end of the output shaft of the servo motor 205, and at least two split hub wheels 201 are fixedly mounted on the surface of the hub core 202 at equal intervals along the axial direction. The circumferential surface of the slitting hub 201 is evenly provided with multiple circumferential grooves 203, and multiple negative pressure holes 204 are equidistantly provided along the length of the circumferential grooves 203. The slitting hub 201 provides negative pressure to each negative pressure hole 204 through the hub negative pressure assembly 3, so that the filter rod is adsorbed in the circumferential groove 203.

[0022] Specifically, such as Figure 1-2As shown, the filter rods entering the slitting circumferential groove 203 are driven by the servo motor 205 to rotate counterclockwise to the blade position of the cutter assembly 7 under negative pressure adsorption. After the blade 701 cuts the filter rods, the filter rods continue to rotate with the slitting hub 201 to the 6 o'clock position. When the slitting circumferential groove 203 no longer adsorbs the filter rods under negative pressure, the chain hook 502 on the transmission chain assembly of the rod output assembly below moves the filter rods in the slitting circumferential groove 203, causing the filter rods to be conveyed downward in the channel groove of the upper mounting plate 102 along the conveying direction of the transmission chain assembly to the gap between the upper ejector wheel 801 and the lower ejector wheel 802 on the rod separation assembly 8. After the filter rods are separated one by one, the dial tooth 902 moves the filter rods into the dial groove 10205 of the smoke extraction assembly 9 and follows the dial tooth 902 to be conveyed downward into the downstream process.

[0023] The adhesive removal component 4 includes a support block 402, which is fixed to the surface of the vertical mounting plate 101 with adjustable left and right positions. A transparent cover 403 is fixedly installed on the other side of the support block 402. A lead screw slide assembly 404 is fixedly installed on the top surface of the inner wall of the transparent cover 403. A connecting block 406 is fixedly installed on the sliding surface of the lead screw slide assembly 404. Scraper blades 401 are fixedly installed at both ends of the connecting block 406 near the cutting hub 201. The lead screw of the lead screw slide assembly 404 is provided with an adjustment handle 40401. The scraper blades 401 extend out of the transparent cover 403 by turning the adjustment handle 40401 and extend into the cutting gap between two adjacent cutting hubs 201 to remove the residual adhesive generated during cutting.

[0024] Specifically, such as Figure 5-6 As shown, driven by the servo motor 205, the slitting hub 201 rotates counterclockwise to the lower end, and the filter rod falls off from the circumferential groove 203. The adjusting handle 40401 finely adjusts the gap between the scraper blade 401 and the adjacent slitting hub 201 relative to the groove of the slitting hub, so that the scraper blade 401 can extend into the groove. After the slitting hub 201 completes a full rotation, the scraper blade 401 simultaneously performs a complete scraping of the groove wall to thoroughly remove the residual adhesive.

[0025] The cutting assembly 7 includes a blade 701, and blade cleaning assemblies 702 are provided at the bottom of the left and right sides of the blade 701. The two sets of blade cleaning assemblies 702 remove the adhesive residue on the surface of the blade 701.

[0026] Specifically, such as Figure 7 As shown, this structure is equipped with blade cleaning components 702 at both ends of the blade 701 of the cutting assembly 7 to remove residual adhesive from the blade surface; at the same time, an adhesive removal component 4 is provided in the slitting hub assembly 2 to specifically clean residual adhesive in the slitting hub groove. The above two cleaning devices can prevent residual adhesive from causing quality defects such as uneven cuts, burrs, or stains on the filter rod during blade cutting.

[0027] The transmission chain assembly consists of a drive wheel, a driven wheel, a tension wheel, and a chain 501 that rotatably connects them. The drive wheel is fixedly installed on the drive shaft of the drive assembly 503, and multiple chain hooks 502 are evenly fixedly installed on the surface of the chain 501.

[0028] Specifically, such as Figure 3-4 As shown, the height of the transmission chain assembly is adjusted by the lifting adjustment component 504 at the upper end of the lateral adjustment component 505. The lateral adjustment component 505 adjusts the horizontal position and horizontal angle of the transmission chain assembly so that the chain 501 and the chain hook 502 are aligned with the lowest circumferential groove 203 of the cutting hub wheel 201. In the filter rod conveying channel formed by the left guide channel 11 and the right guide channel 10, the drive component 503 drives the transmission chain assembly to rotate, thereby driving the chain hook 502, which is equidistantly arranged on the chain, to reciprocate in a circular motion, so as to effectively move and output the filter rod in the cutting circumferential groove 203. During the commissioning and installation process, after the bar output assembly 5 is fixed to the lower mounting plate 103 by the lateral adjustment assembly 505, the jog cylinder is then operated to raise the transmission chain assembly to the set height. Then, the lateral adjustment assembly 505 is moved to adjust the front and rear position of the transmission chain assembly 501 on the lower mounting plate 103 so that it is aligned with the filter bar channel groove of the upper mounting plate 102. Then, the tilt adjustment function of the lateral adjustment assembly 505 is used to correct the angular deviation of the transmission chain assembly 501 relative to the channel groove. After the adjustment is completed, the chain hook 502 on the transmission chain assembly 501 and the cutting circumferential groove 203 maintain a preset distance.

[0029] The bar separation assembly 8 includes a fixed plate 804 and a cylinder lifting assembly 805. The fixed plate 804 and the cylinder lifting assembly 805 are respectively fixedly installed on the top and bottom sides of the upper mounting plate 102. A rotary motor 803 is fixedly installed on one side of the fixed plate 804 and the lifting end of the cylinder lifting assembly 805. An upper ejector wheel 801 and a lower ejector wheel 802 are respectively fixedly installed on the output shafts of the two rotary motors 803. The upper ejector wheel 801 and the lower ejector wheel 802 are driven to rotate in opposite directions by the two rotary motors 803, and the gap between them is located in the filter bar channel groove.

[0030] Specifically, such as Figure 8 As shown, the cylinder lifting assembly 805 adjusts the height of the upper ejector wheel 801, thereby adjusting the relative distance with the lower ejector wheel 802. The fixing plate 804 finely adjusts the lower ejector wheel by adjusting the screw so that there is only one filter rod passing through the gap between the two ejector wheel grooves. The two rotary motors 803 drive the upper and lower ejector wheels to rotate in opposite directions, thereby achieving the effect of separating the filter rods one by one.

[0031] The smoke-dispensing assembly 9 includes a conveyor motor 903, which is fixedly mounted on the bottom surface of the upper mounting plate 102. The output shaft of the conveyor motor 903 passes through the top surface of the upper mounting plate 102 and is fixedly mounted in the center of the dial 901 (e.g., keyed connection, interference fit, etc.). Multiple dial teeth 902 are evenly arranged on the circumferential surface of the dial 901. The dial teeth 902 are rotated by the conveyor motor 903 and push the filter rod to be conveyed.

[0032] Specifically, such as Figure 3-4 As shown, the transmission motor 903 causes the dial 901 and its dial teeth 902 to move in a circular motion within the dial groove on the upper mounting plate 102. After the filter rod is separated, it rotates with the dial 901 under the drive of the dial teeth 902 and is conveyed downward.

[0033] Working principle of this filter rod cutting and conveying device: Step 1: Sequentially fix the slitting hub assembly 2, hub negative pressure assembly 3, adhesive removal assembly 4, baffle assembly 6, cutter assembly 7, bar output assembly 5, bar separation assembly 8, smoke removal assembly 9, left guide channel 11, and right guide channel 10 to the corresponding holes in the support frame 1 to complete the alignment adjustment; connect the electrical and pneumatic circuits and set the process parameters to the standard values.

[0034] Step 2: Driven by the servo motor 205, the filter rod rotates counterclockwise to the blade 701 of the left cutting assembly 7 for cutting. After cutting, the negative pressure adsorption causes the filter rod to continue moving with the cutting circumferential groove 203 to the lowest point. The blade cleaning assembly 702 simultaneously removes impurities from the blade surface, and the adhesive removal assembly 4 scrapes off the adhesive in the groove to ensure that the cut is flat and free of stains.

[0035] Step 3: Driven by the drive assembly 503, the transmission chain assembly 501 pulls the slit filter rods out of the circumferential groove 203 and into the conveying channel formed by the upper ejector wheel 801 and the lower ejector wheel 802, realizing the separation and throwing of the filter rods; then, the filter rods enter the smoke-dispensing groove, and the dispensing disc 901 rotates circumferentially under the drive of the transmission motor 903, and the filter rods are pushed to the outlet by the dispensing disc teeth 902 to complete the conveying.

[0036] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
