Description

Technical Field

[0001] The utility model relates to the field of cigarette production equipment, and more specifically to a tipping paper cutting device with a self-cleaning function. Background Art

[0002] Cigarette tipping paper is used to wrap the outside of the filter. The tipping paper wraps the cut filter segments and the cigarette rod together to form a filter cigarette.

[0003] In the prior art, the tipping paper is cut by a paper cutting device equipped with a cutter. However, since there is glue on the tipping paper, part of the glue will adhere to the back of the cutter when the cutter is cutting the tipping paper. The glue on the cutter accumulates over time and makes the cutter have a certain degree of adhesion, which affects the effect of the cutter in cutting the tipping paper. The existing solution is to remove the cutter device and clean the cutter after the cutter has been used for a short period of time. However, removing the cutter device requires shutting down the entire equipment, and frequent shutdowns to clean the cutter seriously affect production efficiency. Utility Model Content

[0004] The utility model aims to overcome the problem that the cutter in the prior art needs to be frequently stopped to clean glue, and provides a tipping paper cutting device with a self-cleaning function, which can remove glue on the cutter without stopping the machine.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a tipping paper cutting device with a self-cleaning function, comprising a cutter cover and a cutter installed in the cutter cover, the surface of the cutter is provided with an anti-stick coating; the surface of the cutter cover is provided with a discharge structure for discharging foreign matter in the cutter cover, and a blowing component is provided in the cutter cover, and the blowing component blows the foreign matter in the cutter cover toward the discharge structure.

[0006] In the above technical solution, the cutter is a circular cutter, and the anti-stick coating of the cutter prevents the glue of the tipping paper from adhering to the surface of the cutter. Instead, it forms flocculent or granular solid glue on the surface of the cutter. The solid glue will leave the cutter as the cutter rotates at high speed and fall into the cutter cover to become a foreign body in the cutter cover. The blowing component blows out compressed air in the cutter cover, and the compressed air blows the solid glue toward the discharging structure to make the solid glue leave the cutter cover. At the same time, the compressed air forms an airflow in the cutter cover, which will also accelerate the solid glue to leave the cutter. Since the glue will not adhere to the cutter, the cutter will not need to be stopped to remove the glue because the glue affects its sharpness. At the same time, timely discharge of the solid glue also prevents it from accumulating in the cutter cover and affecting the cutting of the tipping paper.

[0007] Preferably, the blowing assembly includes a first blowing block installed at the bottom of the cutter cover and a first air supply head connected to the first blowing block, the first blowing block is provided with a first air outlet; the discharging structure includes a first outlet provided on the surface of the cutter cover, the first outlet is close to the bottom surface of the cutter cover; the first air outlet faces the position where the first outlet is located. Solid glue will fall to the bottom due to gravity, the first blowing block is provided at the bottom of the cutter cover, and the first outlet is also located close to the bottom surface of the cutter cover, the compressed air blown out of the first outlet is blown along the bottom surface toward the first outlet, and the fixing glue is blown into the first outlet.

[0008] Preferably, the first blowing block is located on a side close to the cutting edge of the cutting blade cover, the first discharging port is located on a side away from the cutting edge, the length of the first blowing block is consistent with the width of the bottom surface of the cutting blade cover, and a plurality of the first air outlets are arranged along the length direction of the first blowing block. The cutting edge of the cutting blade cover is an opening where the cutting blade contacts the tipping paper, and the cutting blade cuts the tipping paper at the cutting edge. The cutting edge is located on one side of the cutting blade cover. When the first blowing block is located on a side close to the cutting edge and the second discharging port is located on a side away from the cutting edge, the compressed air blown out of the first air outlet can flow from one side of the bottom surface of the cutting blade cover to the other side. In addition, the length of the first blowing block is consistent with the width of the bottom surface of the cutting blade cover, so that the compressed air blown out of the first air outlet can eventually cover the bottom surface of the cutting blade cover.

[0009] Preferably, the cutter cover is provided with a mounting plate at the top of the cutter mouth, and the mounting plate and the cutter cover form a accommodating cavity; the blowing assembly also includes a second blowing block installed on the mounting plate and a second air supply head connected to the second blowing block, and the second blowing block is provided with a second air outlet; the discharging structure also includes a second discharge port arranged on the surface of the cutter cover and connected to the accommodating cavity, and the second air outlet is facing the position where the second discharge port is located. The cutter is a circular cutter. In addition to falling due to gravity, the solid glue will also separate from the cutter due to centrifugal force when the cutter rotates at a rated time. If the fixed glue separates from the cutter when it is at the top of the cutter, the fixed glue will make a horizontal throwing motion along the tangent direction of the cutter and may be thrown above the cutter edge and fall from above the cutter edge. In order to prevent the solid glue from falling and affecting the slitting of the tipping paper, a accommodating cavity is formed above the cutter edge through the mounting plate, so that the solid glue can make a horizontal throwing motion along the tangent direction of the cutter and enter the accommodating cavity and fall on the mounting plate, and then the compressed air blown out by the second blowing block blows the solid glue on the mounting plate to the second discharge port.

[0010] In the above solution, both the first air supply head and the second air supply head are connected to air pipes for supplying compressed air.

[0011] Preferably, the mounting plate is parallel to the tangent direction of the cutter, so as to avoid interference of the mounting plate with the movement of the cutter and provide as large an accommodation space as possible.

[0012] Preferably, the second air blowing block is located at one end of the mounting plate away from the second discharge port. A plurality of second air outlets are arranged in a direction perpendicular to the axis of the second discharge port. The compressed air blown out by the second air blowing block through the second air outlet can cover the entire mounting plate, and blow the solid glue on the mounting plate into the second discharge port as much as possible.

[0013] Preferably, the discharge structure includes a discharge pipe connected to the first discharge port and the second discharge port respectively, and the discharge pipe is installed on the surface of the cutter cover. The discharge pipe can extend outside the entire paper cutting device to collect solid glue outside the device to prevent the solid glue from entering other components and affecting the operation of other components.

[0014] Preferably, the inner surface of the cutter cover is also provided with an anti-stick coating to prevent glue from adhering to the inner surface of the cutter cover.

[0015] Preferably, the anti-stick coating is a Teflon coating.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows: the anti-stick coating of the cutter prevents the glue of the tipping paper from adhering to the surface of the cutter, but forms flocculent or granular solid glue on the surface of the cutter, and the blowing component blows the solid glue out to the discharging structure and discharges it through the discharging structure, the glue will not adhere to the cutter and the solid glue can be discharged in time, there is no need to stop the machine to clean the glue on the cutter and clean the solid glue left in the cutter cover, the operating time of the equipment is increased by reducing the number of shutdowns, thereby improving production efficiency.

[0023] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0024] Example 1

[0025] like Figure 1-3 The figure shows an embodiment 1 of a tipping paper cutting device with a self-cleaning function, comprising a cutter cover 1 and a cutter 2 installed in the cutter cover 1, wherein the surface of the cutter 2 is provided with an anti-stick coating; a discharge structure for discharging foreign matter in the cutter cover 1 is installed on the surface of the cutter cover 1, and a blowing component is provided in the cutter cover 1, and the blowing component blows the foreign matter in the cutter cover 1 toward the discharge structure.

[0026] Specifically, the blowing assembly includes a first blowing block 3 installed at the bottom of the cutter cover 1 and a first air supply head 4 connected to the first blowing block 3, the first blowing block 3 is provided with a first air outlet 301; the discharging structure includes a first discharge port 5 provided on the surface of the cutter cover 1, the first discharge port 5 is close to the bottom surface of the cutter cover 1; the first air outlet 301 is toward the position where the first discharge port 5 is located. The solid glue will fall to the bottom due to the influence of gravity, the first blowing block 3 is provided at the bottom of the cutter cover 1, and the first discharge port 5 is also located near the bottom surface of the cutter cover 1, and the compressed air blown out of the first air outlet 301 is blown along the bottom surface toward the first discharge port 5, and the fixed glue is blown into the first discharge port 5.

[0027] Further, the first blowing block 3 is located on a side close to the cutting opening 101 of the cutting cover 1, the first discharging port 5 is located on a side away from the cutting opening 101, the length of the first blowing block 3 is consistent with the width of the bottom surface of the cutting cover 1, and a plurality of first air outlets 301 are arranged along the length direction of the first blowing block 3. The cutting opening 101 of the cutting cover 1 is an opening where the cutting knife 2 contacts the tipping paper, and the cutting knife 2 cuts the tipping paper at the cutting opening 101. The cutting opening 101 is located on one side of the cutting cover 1. When the first blowing block 3 is located on a side close to the cutting opening 101 and the second discharging port 8 is located on a side away from the cutting opening 101, the compressed air blown out of the first air outlet 301 can flow from one side of the bottom surface of the cutting cover 1 to the other side. In addition, the length of the first blowing block 3 is consistent with the width of the bottom surface of the cutting cover 1, so that the compressed air blown out of the first air outlet 301 can cover the bottom surface of the cutting cover 1. In this embodiment, in order to avoid interference between the first discharge port 5 and components other than the cutter cover 1, the first discharge port 5 is arranged on the side of the cutter cover 1 facing outward, so that the axis of the first discharge port 5 is perpendicular to the direction of the first air outlet 301. However, when the compressed air blows the solid glue toward the first discharge port 5, since the first discharge port 5 is connected to the outside and has a certain low pressure, the fixed glue will still enter the first discharge port 5 and then be discharged. In this embodiment, the first air supply head 4 is connected to an air pipe for supplying compressed air, which can be a air pipe connector.

[0028] In this embodiment, the inner surface of the cutter cover 1 is also provided with an anti-stick coating to prevent glue from adhering to the inner surface of the cutter cover 1. Specifically, the anti-stick coating is a Teflon coating.

[0029] The working principle or working process of this embodiment is as follows: the cutter 2 is a circular cutter 2, and the anti-stick coating of the cutter 2 prevents the glue of the tipping paper from adhering to the surface of the cutter 2, but forms flocculent or granular solid glue on the surface of the cutter 2. The solid glue will leave the cutter 2 and fall into the bottom of the cutter cover 1 as the cutter 2 rotates at high speed, becoming a foreign body in the cutter cover 1. The first blowing block 3 of the blowing assembly blows out compressed air through the first air outlet 301, and the compressed air blows the solid glue at the bottom of the cutter cover 1 toward the first discharge port 5 of the discharge structure, so that the solid glue leaves the cutter cover 1. At the same time, the compressed air forms an airflow in the cutter cover 1, which also accelerates the solid glue to leave the cutter 2. Since the glue will not adhere to the cutter 2, the cutter 2 will not need to be stopped to remove the glue because the glue affects its sharpness. At the same time, timely discharge of the solid glue also prevents it from accumulating in the cutter cover 1 and affecting the cutting of the tipping paper.

[0030] Beneficial effects of this embodiment: the anti-stick coating of the cutter 2 prevents the glue of the tipping paper from adhering to the surface of the cutter 2, but forms flocculent or granular solid glue on the surface of the cutter 2, and the blowing component blows the solid glue out to the discharging structure and discharges it through the discharging structure. The glue will not adhere to the cutter 2 and the solid glue can be discharged in time. There is no need to stop the machine to clean the glue on the cutter 2 and clean the solid glue left in the cutter cover 1. The operating time of the equipment is increased by reducing the number of shutdowns, thereby improving production efficiency.

[0033] The cutter cover 1 is located at the top of the cutter mouth 101 and is provided with a mounting plate 102, the mounting plate 102 is parallel to the tangent direction of the cutter 2, and the mounting plate 102 and the cutter cover 1 form a accommodating cavity; the blowing assembly also includes a second blowing block 6 installed on the mounting plate 102 and a second air supply head 7 connected to the second blowing block 6, and the second blowing block 6 is provided with a second air outlet 601; the discharging structure also includes a second discharge port 8 arranged on the surface of the cutter cover 1 and connected to the accommodating cavity, and the second air outlet 601 faces the position where the second discharge port 8 is located. The cutter 2 is a circular cutter 2. In addition to falling due to gravity, the solid glue will also separate from the cutter 2 due to centrifugal force when the cutter 2 rotates at the rated time. If the fixed glue separates from the cutter 2 when it is at the top of the cutter 2, the fixed glue will make a horizontal throwing motion along the tangential direction of the cutter 2 and may be thrown above the cutter edge 101 and fall from above the cutter edge 101. In order to prevent the solid glue from falling and affecting the cutting of the tipping paper, a accommodating cavity is formed above the cutter edge 101 through the mounting plate 102, so that the solid glue can make a horizontal throwing motion along the tangential direction of the cutter 2 and then enter the accommodating cavity and fall on the mounting plate 102. At the same time, the mounting plate 102 is parallel to the tangential direction to avoid interference with the cutter 2. Then, the compressed air blown out by the second blowing block 6 blows the solid glue on the mounting plate 102 toward the second discharge port 8.

[0034] Further, the second blowing block 6 is located at one end of the mounting plate 102 away from the second discharge port 8. A plurality of second air outlets are arranged in a direction perpendicular to the axis of the second discharge port 8. The compressed air blown out by the second blowing block 6 through the second air outlets can cover the entire mounting plate 102, and blow the solid glue on the mounting plate 102 into the second discharge port 8 as much as possible.

The outlet end of the second pipe 902 is connected to the first pipe 901, and the outlet end of the first pipe 901 extends to the outside of the paper cutting device. The discharge pipe 9 can extend to the outside of the entire paper cutting device, collect solid glue outside the device, and prevent the solid glue from entering other components and affecting the operation of other components.
