Abstract
Description
Technical Field
[0001] This application relates to the field of tobacco processing technology, and in particular to a device for recycling cork paper scraps. Background Technology
[0002] Tipping paper is a type of decorative paper obtained by printing, coating, and other processing of tipping base paper. It improves the appearance of cigarettes. Nowadays, perforated tipping paper, when combined with high-transparency forming paper, also has the effect of reducing tar. Common tipping papers are orange-yellow and white. During cigarette production, tipping paper needs to be cut to a certain size for subsequent packaging. However, cutting tipping paper generates waste paper, so a special waste paper recycling device is needed to collect the waste paper and avoid shredded paper affecting the cleanliness of the factory.
[0003] Existing tipping paper scrap recycling devices include a collection box, a fan, and a conveying pipe. One end of the conveying pipe is connected to the collection box, and the other end is connected to the discharge end of the tipping paper cutting equipment. The fan generates suction, causing the tipping paper scraps generated at the discharge end of the tipping paper cutting equipment to fall into the collection box through the conveying pipe. In related technologies, a filter screen is installed inside the collection box to separate the tipping paper scraps from dust.
[0004] However, existing tipping paper scrap recycling devices rely on gravity to allow dust mixed in with the tipping paper to fall into the collection box, resulting in poor separation efficiency. Utility Model Content
[0005] Therefore, it is necessary to provide a tipping paper scrap recycling device to address the problem of poor separation effect between tipping paper scraps and dust.
[0006] This application provides a tipping paper scrap recycling device, the tipping paper scrap recycling device comprising:
[0007] A collection box, wherein a boss is provided on the cavity wall of the collection box;
[0008] A filter screen is disposed within the receiving cavity and overlaps the protrusion to divide the receiving cavity into a first cavity and a second cavity;
[0009] The feeding pipe has one end connected to the first cavity and the other end connected to the discharge end of the tipping paper cutting equipment.
[0010] A vibration assembly is disposed within the second cavity and connected to the cavity wall of the second cavity. The vibration assembly includes a rotating shaft and a cam connected to each other. The rotating shaft can drive the cam to rotate, so that the cam pushes the filter screen to move.
[0011] An elastic element is disposed in the second cavity, with one end of the elastic element connected to the filter screen and the other end connected to the cavity wall of the second cavity.
[0012] In one embodiment, the tipping paper scrap recycling device further includes a humidification component, the humidification component comprising:
[0013] A water tank is located outside the receiving cavity;
[0014] A first transport pipe is located inside the second cavity, and a water outlet is provided on the first transport pipe;
[0015] The second transport pipe has one end connected to the water tank and the other end connected to the first transport pipe.
[0016] In one embodiment, the cork paper scrap recycling device further includes a box covering the collection box, the collection box being slidable relative to the box, and the length direction of the first transport pipe being parallel to the sliding direction of the collection box.
[0017] In one embodiment, multiple first transport pipes are provided, and each of the multiple first transport pipes is connected to a second transport pipe. The multiple first transport pipes are arranged at intervals along a first direction, wherein the first direction is perpendicular to the sliding direction of the collection box.
[0018] In one embodiment, the humidification assembly further includes a water pump disposed within the water tank, the water pump being used to allow liquid in the water tank to flow into the second transport pipe.
[0019] In one embodiment, the cavity wall of the first cavity is provided with a limiting member, the boss and the limiting member are arranged at intervals along the height direction of the collection box, and a portion of the filter screen is located between the boss and the limiting member.
[0020] In one embodiment, the vibration assembly further includes a vibration source, a driving gear, and a driven gear. The driving gear is connected to the output end of the vibration source, the driving gear and the driven gear mesh, and the driven gear is connected to the rotating shaft.
[0021] In one embodiment, the vibration assembly further includes a sealing box, the vibration source is disposed inside the sealing box, the filter screen includes a filter hole area and a solid area, and the sealing box is connected to the solid area.
[0022] In one embodiment, the vibration assembly further includes a fixing block, which is sleeved on the rotating shaft and rotatably engaged with the rotating shaft, with at least a portion of the outer wall of the fixing block abutting against the cavity wall of the second cavity.
[0023] In one embodiment, the cork paper scrap recycling device further includes a connecting column, through which the elastic element is connected to the cavity wall of the second cavity.
[0024] The aforementioned tipping paper scrap recycling device places the filter screen within the receiving cavity of the collection box by attaching it to a protrusion, thus dividing the receiving cavity into a first cavity and a second cavity. A conveying pipe connects the first cavity to the discharge end of the tipping paper cutting equipment. Tipping paper scraps produced at the discharge end of the cutting equipment are transported to the first cavity via the conveying pipe. Under gravity, dust falls through the filter screen into the second cavity. A vibration component is installed in the second cavity. The rotating shaft of the vibration component drives a cam to rotate, causing the protruding area of the cam to abut against the filter screen, pushing the filter screen away from the protrusion. As the cam continues to rotate, the filter screen falls under gravity. The continued rotation of the cam causes the filter screen to vibrate, further causing dust from the tipping paper scraps and the filter screen to fall into the second cavity. Furthermore, an elastic element is installed in the second cavity. Because the elastic element is connected to the filter screen, it acts as a buffer during the up-and-down vibration of the filter screen, reducing the impact of the filter screen on the overall device and protecting the filter screen from damage.
[0025] The tipping paper scrap recycling device of this application promotes the separation of dust mixed in with tipping paper scraps. Compared with the existing method that relies solely on gravity separation of dust, it improves the dust separation efficiency, reduces dust residue, and ensures the cleanliness of tipping paper scraps.

[0047] This application provides a tipping paper scrap recycling device, which includes: a collection box 100, a filter screen 200, a conveying pipe 300, a vibration assembly 400, and an elastic element 500. The collection box 100 has a boss on the cavity wall. The filter screen 200 is disposed in the cavity and overlaps the boss to divide the cavity into a first cavity 110 and a second cavity 120. One end of the conveying pipe 300 is connected to the first cavity 110, and the other end is connected to the discharge end of the tipping paper cutting equipment. The vibration assembly 400 is disposed in the second cavity 120 and connected to the cavity wall of the second cavity 120. The vibration assembly 400 includes a rotating shaft 410 and a cam 420 connected to each other. The rotating shaft 410 can drive the cam 420 to rotate, so that the cam pushes the filter screen 200 to move. The elastic element 500 is disposed in the second cavity 120, with one end connected to the filter screen 200 and the other end connected to the cavity wall of the second cavity 120.
[0048] The aforementioned tipping paper scrap recycling device places the filter screen 200 on the protrusion of the receiving cavity of the collection box 100, thereby dividing the receiving cavity into a first cavity 110 and a second cavity 120. A conveying pipe 300 connects the first cavity 110 to the discharge end of the tipping paper cutting equipment. Tipping paper scraps produced at the discharge end of the cutting equipment are transported to the first cavity 110 via the conveying pipe 300. Under gravity, dust falls through the filter screen 200 into the second cavity 120. By installing a vibration component 400 within the second cavity 120, the rotating shaft 410 of the vibration component 400 drives the cam 420 to rotate, causing the protruding area of the cam 420 to abut against the filter screen 200, pushing the filter screen 200 away from the protrusion. As the cam 420 continues to rotate, the filter screen 200 falls under the influence of gravity. The continued rotation of the cam 420 causes the filter screen 200 to vibrate, further causing dust from the cork paper fragments and the dust on the filter screen 200 to fall into the second cavity 120. Furthermore, by installing an elastic element 500 within the second cavity 120, which is connected to the filter screen 200, the elastic element 500 acts as a buffer during the up-and-down vibration of the filter screen 200, reducing the impact of the filter screen 200 on the overall device and protecting the filter screen 200 from damage.
[0049] The tipping paper scrap recycling device of this application promotes the separation of dust mixed in with tipping paper scraps. Compared with the existing method that relies solely on gravity separation of dust, it improves the dust separation efficiency, reduces dust residue, and ensures the cleanliness of tipping paper scraps.
[0050] It should be noted that the filter screen 200 overlaps the boss, that is, the edge area of the filter screen 200 is stacked on the boss, so that the filter screen 200 is placed in the receiving cavity.
[0051] In one specific embodiment, the elastic element 500 is a spring.
[0052] In one embodiment, such as Figure 2 and Figure 3 As shown, the vibration assembly 400 also includes a vibration source 430, a driving gear 440, and a driven gear 450. The driving gear 440 is connected to the output end of the vibration source 430, and the driving gear 440 and the driven gear 450 mesh. The driven gear 450 is connected to the rotating shaft 410. By setting the driving gear 440 and the driven gear 450, the power of the vibration source 430 is transmitted to the rotating shaft 410, which facilitates the rotating shaft 410 to drive the cam 420 to rotate.
[0053] In one specific embodiment, the vibration source 430 is a motor.
[0054] In one embodiment, such as Figure 2 and Figure 3As shown, the vibration assembly 400 also includes a sealing box 460, with the vibration source 430 disposed within the sealing box 460. The filter screen 200 includes a filter hole area and a solid area, and the sealing box 460 is connected to the solid area. By installing the vibration source 430 within the sealing box 460 and connecting the sealing box 460 to the solid area, dust from the second chamber 120 is prevented from falling into the vibration source 430 and affecting its working efficiency.
[0055] It should be noted that the filter hole area of filter 200 refers to the area on filter 200 with holes, while the solid area of filter 200 refers to the area on filter 200 without holes.
[0056] In one embodiment, such as Figure 2 and Figure 3 As shown, the vibration assembly 400 also includes a fixing block 470, which is sleeved on the rotating shaft 410 and rotatably engaged with it. At least a portion of the outer wall of the fixing block 470 is in contact with the cavity wall of the second cavity 120. By providing the fixing block 470, at least a portion of the outer wall of the fixing block 470 is in contact with the cavity wall of the second cavity 120, and the rotating shaft 410 is supported by the fixing block 470.
[0057] In one embodiment, such as Figure 4 As shown, the cork paper scrap recycling device also includes a connecting post 510, through which the elastic element 500 is connected to the cavity wall of the second cavity 120. By providing the connecting post 510, the end of the elastic element 500 facing away from the filter screen 200 is connected to the connecting post 510, and the connecting post 510 is connected to the cavity wall of the second cavity 120, thereby achieving the connection between the elastic element 500 and the cavity wall of the second cavity 120.
[0058] In one embodiment, the cavity wall of the first cavity 110 is provided with a limiting member. The boss and the limiting member are arranged at intervals along the height direction of the collection box 100, and a portion of the filter screen 200 is located between the boss and the limiting member. By providing the limiting member, a portion of the filter screen 200 is located between the boss and the limiting member, that is, the limiting member is used to limit the upper limit of the filter screen 200, thereby limiting the vibration height of the filter screen 200.
[0059] In one embodiment, such as Figure 1 , Figure 2 as well as Figure 5As shown, the tipping paper scrap recycling device also includes a humidification component 600, which includes a water tank 610, a first transport pipe 620, and a second transport pipe 630. The water tank 610 is located outside the receiving cavity; the first transport pipe 620 is located inside the second cavity 120 and has a water outlet; one end of the second transport pipe 630 is connected to the water tank 610, and the other end is connected to the first transport pipe 620. By setting up the humidification component 600, the liquid in the water tank 610 can flow into the second cavity 120 sequentially through the second transport pipe 630, the first transport pipe 620, and the water outlet, and drip onto the dust, increasing the gravity of the dust and preventing the dust from being stirred up again. Moreover, the liquid will not come into contact with the tipping paper above, achieving dry and wet separation, which facilitates the subsequent secondary processing of the tipping paper.
[0060] In one specific embodiment, such as Figure 1 , Figure 2 as well as Figure 5 As shown, the humidification assembly 600 also includes a water pump 640 disposed in the water tank 610, which is used to allow the liquid in the water tank 610 to flow into the second transport pipe 630. By providing the water pump 640 in the water tank 610, it is convenient to pump the liquid in the water tank 610 into the second transport pipe 630.
[0061] In one embodiment, such as Figure 1 , Figure 2 as well as Figure 5 As shown, the cork paper scrap recycling device also includes a housing 700 covering the collection box 100. The collection box 100 can slide relative to the housing 700, and the length direction of the first transport pipe 620 is parallel to the sliding direction of the collection box 100. By setting the housing 700, the collection box 100 is disposed inside the housing 700, and the housing 700 protects the collection box 100. The fact that the length direction of the first transport pipe 620 is parallel to the sliding direction of the collection box 100 prevents the first transport pipe 620 from affecting the sliding of the collection box 100.
[0062] In this embodiment, as Figure 1 and Figure 2 As shown, the collection box 100 has a U-shaped structure. The filter 200 installed inside the collection box 100 divides the collection box 100 into a first cavity 110 and a second cavity 120 along the height direction.
[0063] In this embodiment, as Figure 1 and Figure 2 As shown, it also includes a door 710, which is connected to the housing 700 to seal the housing 700. The door 710 is provided with a drain port that communicates with the second chamber 120. The drain port is provided with a sealing plug 720. When it is necessary to drain the liquid in the second chamber 120, the sealing plug 720 is removed, allowing the liquid in the second chamber 120 to be discharged to the outside through the drain port.
[0064] In this embodiment, as Figure 1 , Figure 2 as well as Figure 5 As shown, multiple first transport pipes 620 are provided, and each of the multiple first transport pipes 620 is connected to a second transport pipe 630. The multiple first transport pipes 620 are arranged at intervals along a first direction, wherein the first direction is perpendicular to the sliding direction of the collection box 100. By providing multiple first transport pipes 620, and ensuring that each of the multiple first transport pipes 620 is connected to a second transport pipe 630, liquid in the second transport pipe 630 can flow into the multiple first transport pipes 620 respectively, thereby improving the humidification efficiency.
[0065] In this embodiment, the first direction is the width direction of the collection box 100.
[0066] In one embodiment, such as Figure 1 As shown, the tipping paper scrap recycling device also includes a fan and an installation pipe 800. The installation pipe 800 is connected to the first chamber 110. The suction force generated by the fan can discharge the tipping paper scraps in the first chamber 110 through the installation pipe 800 to the outside of the box 700.
[0067] In one embodiment, such as Figure 1 As shown, a ball valve 810 is installed on the installation pipe 800. The ball valve 810 controls the flow rate of the installation pipe 800, thereby adjusting the wind force generated by the fan. In this way, the paper cutter can clean up the water-soaked paper fragments in a timely manner without stopping the paper cutter, avoiding the problem of waste paper flying everywhere. In particular, it can prevent the waste water-soaked paper from being rolled into the finished cigarette when the paper cutter is started or restarted, forming a second cigarette with waste water-soaked paper, which seriously affects the product quality.
[0068] In one embodiment, such as Figure 1 As shown, a mounting bracket 900 is provided on the top wall of the enclosure 700 to facilitate the installation and fixation of the enclosure 700.
[0069] In summary, the beneficial effects of this application are:
[0070] 1. By utilizing the vibration generated by the rotation of cam 420 and the assistance of elastic element 500, the separation of dust mixed in the tipping paper fragments is effectively promoted. Compared with the existing separation method that relies solely on the gravity of dust, the separation efficiency of dust is significantly improved, dust residue is reduced, and the cleanliness of tipping paper fragments is ensured.
[0071] 2. By spraying liquid onto the dust to increase its gravity, the dust is further prevented from flying, effectively protecting the health of the staff and avoiding the adverse effects caused by inhaling dust.
[0072] 3. Clean up the tipping paper scraps in a timely manner without stopping the paper cutter. This not only avoids the problem of waste paper flying everywhere, but also reduces production interruptions caused by machine downtime for cleaning, thus improving production efficiency.
[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0074] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
