Description

Technical Field

[0001] The invention relates to the technical field of cigarette production, in particular to an acceleration wheel and a cutting device. Background Art

[0002] As the main filter rod in cigarette production, the relevant process flow of filter rods on the cigarette rolling and connecting machine mainly includes receiving and storing, input cutting, circumferential staggering, horizontal straightening, accelerated transmission, and cigarette feeding. Finally, the filter of the finished cigarette is formed through bonding, splicing, cigarette grouping and cutting.

[0003] The function of the acceleration wheel is to accelerate and transfer the aligned filter rods to the transition wheel in an orderly manner. However, during the acceleration of the filter rods, the stability of the filter rods on the acceleration wheel is limited, and they are prone to tilt or fall, affecting the overall operation of the slitting device. Summary of the invention

[0004] Based on this, it is necessary to provide an acceleration wheel and a slitting device to address the problem of limited stability of the filter rod on the acceleration wheel.

[0005] An acceleration wheel, comprising:

[0006] Axis body;

[0007] A wheel body, wherein the wheel body is sleeved on the outer circumference of the shaft body, a clamping portion is provided on the outer circumference of the wheel body, a clamping space is provided on the clamping portion, an air flow channel is provided inside the wheel body, the air flow channel is arranged around the shaft body in the wheel body, and the air flow channel is communicated with the clamping space;

[0008] A valve body is sleeved on the outer circumferential surface of the shaft body, an air intake channel is arranged inside the valve body, an arc-shaped groove body connected with the air intake channel is arranged on the side of the valve body, and the arc-shaped groove body is connected with the air flow channel.

[0009] The above-mentioned acceleration wheel can, after being installed on the slitting device, connect the air suction channel in the valve body with the negative pressure suction device on the slitting device, so that when the transmission shaft drives the acceleration wheel to rotate, the negative pressure suction device can suck out the air in the acceleration wheel through the air valve, so that the filter rod located in the clamping space can be adsorbed on the clamping part, thereby improving the stability of the filter rod on the acceleration wheel.

[0010] In one embodiment, a plurality of the air intake channels are provided, and the plurality of air intake channels are arranged in a semi-circular shape inside half of the valve body (3).

[0011] In the above embodiment, since the acceleration wheel only needs to fix the filter rod in a half-circle path, the air intake channel is concentrated on one-half of the valve body, which can reduce the processing amount while ensuring the filter rod fixing effect.

[0012] In one embodiment, along the axial direction of the shaft body, the two ends of the valve body respectively have a first side surface and a second side surface, the first side surface of the valve body is provided with an arcuate waist groove, the arcuate groove body is arranged on the second side surface of the valve body, and the two ends of the air intake channel are respectively connected with the arcuate waist groove and the arcuate groove body.

[0013] In the above embodiment, the setting of the arc-shaped waist groove facilitates multiple suction channels to be connected to the negative pressure suction device on the slitting device at the same time, and the setting of the arc-shaped waist groove facilitates multiple suction channels to be connected to the air flow channel of the wheel body at the same time.

[0014] In one embodiment, the valve body includes a first connecting body and a second connecting body, the second connecting body is connected to the first connecting body, and the second connecting body is located between the first connecting body and the wheel body, and the outer diameter of the first connecting body is greater than the outer diameter of the second connecting body.

[0015] In the above embodiment, since the valve body can be connected to the wheel body through the second connecting body, and the valve body can be connected to the cutting device through the first connecting body, when the outer diameter of the first connecting body is larger than the outer diameter of the second connecting body, it can ensure that the contact area between the valve body and the cutting device is larger and the connection effect is better.

[0016] In one of the embodiments, the acceleration wheel further includes at least one adjusting member, the adjusting member is sleeved on the outer circumferential surface of the shaft body, and a through hole is provided on the adjusting member, and the through hole is communicated with the air intake channel.

[0017] In the above embodiment, by adjusting the number or thickness of the adjusting parts, the gap between the valve body and the slitting device can be adjusted, thereby changing the gap between the valve body and the wheel body. While ensuring that the gap between the wheel body and the valve body does not affect the air suction requirements, it also ensures that the valve body does not affect the normal rotation of the wheel body.

[0018] In one embodiment, the valve body is located between the adjusting member and the wheel body.

[0019] In the above embodiment, by placing the adjusting member at the side of the valve body away from the wheel body, the adjusting member will not affect the air suction effect between the valve body and the wheel body when adjusting the distance between the valve body and the wheel body.

[0020] In one embodiment, the plurality of clamping parts are arranged on the outer circumference of the wheel body around the shaft body, and the clamping parts are provided with guide surfaces and arc surfaces, and the clamping space is surrounded by the guide surfaces and the arc surfaces.

[0021] In the above embodiment, the filter rod can be guided into the arc surface through the guide surface, so that the arc surface can limit the filter rod. Compared with the V-shaped groove used in the prior art, the arc surface is more conducive to the transfer of the filter rod by the wheel body, and it is also easier to make the filter rod fit with the clamping part, thereby ensuring the stability between the filter rod and the clamping part, and the filter rod is less likely to deform when being adsorbed.

[0022] In one embodiment, the air flow channel includes a first air suction groove and a second air suction groove, the first air suction groove is arranged on the first side surface of the wheel body around the shaft body, the second air suction groove is arranged on the arc surface of the clamping part, and the second air suction groove is connected to the first air suction groove.

[0023] In the above embodiment, the air in the clamping space can be sucked into the valve body through the second suction groove and the first suction groove in sequence, so that the filter rod is adsorbed and fixed in the clamping space.

[0024] A slitting device comprises a mounting frame and the above-mentioned acceleration wheel, wherein the acceleration wheel is arranged on the mounting frame, and the shaft passes through the mounting frame, and the mounting frame is provided with a wheel group and a negative pressure suction device, and the negative pressure suction device is connected to the wheel group and the acceleration wheel.

[0025] The above-mentioned slitting device improves the utilization rate of the negative pressure suction device by making the acceleration wheel and the wheel group share a negative pressure suction device.

[0026] In one embodiment, the wheel set includes a cutting wheel, an offset wheel, a combined wheel and a transition wheel, the offset wheel is arranged between the cutting wheel and the combined wheel, and the acceleration wheel is arranged between the combined wheel and the transition wheel.

[0027] In the above embodiment, the filter rod is cut by a cutting wheel, the cut filter rod segments are circumferentially displaced by a dislocation wheel, the displaced filter rod segments are laterally straightened by a unifying wheel, and the straightened filter rod segments are accelerated and transferred to the transition wheel by an acceleration wheel.

[0062] See also Figures 1 to 4 An embodiment of the present invention provides an acceleration wheel, comprising an axle body 1, a wheel body 2 and a valve body 3. The axle body 1 is used to provide a mounting position for the wheel body 2 and the valve body 3, and can drive the wheel body 2 to rotate after installation, so that the wheel body 2 can transfer a rod-shaped or bar-shaped material, such as a filter rod. The wheel body 2 is used to fix and transfer a rod-shaped or bar-shaped material, such as a filter rod. The valve body 3 is used to extract the air inside the wheel body 2 to enhance the stability of the rod-shaped or bar-shaped material, such as a filter rod, on the wheel body 2.

[0063] The wheel body 2 is sleeved on the outer circumference of the shaft body 1, and a clamping portion 21 is provided on the outer circumference of the wheel body 2, and a clamping space 20 is provided on the clamping portion 21, and the clamping space 20 is communicated. Specifically, the wheel body 2 is a hollow structure, and the wheel body 2 is fixedly connected to the shaft body 1. When the shaft body 1 rotates, the wheel body 2 rotates accordingly. At least two rows of clamping portions 21 are provided on the outer circumference of the wheel body 2, and the two rows of clamping portions 21 can clamp the two sides of the filter rod respectively, thereby enhancing the stability of the filter rod on the wheel body 2. There are multiple clamping portions 21 in each row, and the multiple clamping portions 21 are all arranged on the outer circumference of the wheel body 2 around the shaft body 1. Multiple filter rods can be clamped by the multiple clamping portions 21 on the outer circumference of the wheel body 2. In addition, a fixing seat 4 can be provided on the shaft body 1, and the fixing seat 4 can be connected to the shaft body 1 and the wheel body 2 respectively by tools such as bolts, and the second side surface of the wheel body 2 is abutted against the fixing seat 4 to ensure the stability of the wheel body 2 on the shaft body 1.

[0064] Furthermore, the wheel body 2 is provided with an air flow channel 22, the air flow channel 22 is arranged around the shaft body 1 in the wheel body 2, and the air flow channel 22 is connected to the clamping space 20. Figure 4 Part of the air flow channel 22 is arranged along the axial direction of the wheel body 2. Another part of the air flow channel 22 is connected with the clamping space 20 in the radial direction.

[0065] The valve body 3 is sleeved on the outer circumferential surface of the shaft body 1, and an air intake channel 33 is provided inside the valve body 3. An arc-shaped groove body 35 communicating with the air intake channel 33 is provided on the side of the valve body 3, and the arc-shaped groove body 35 is communicated with the air flow channel 22. Specifically, the distance between the air outlet of the air intake channel 33 and the shaft body 1 is consistent with the distance between the air inlet of the air flow channel 22 and the shaft body 1, and the line between the air outlet of the air intake channel 33 and the air inlet of the air flow channel 22 is parallel to the axis of the shaft body 1. When the distance between the wheel body 2 and the valve body 3 is fixed, the distance between the air intake channel 33 and the air flow channel 22 is the shortest, so that the air in the air flow channel 22 is easier to be drawn into the air intake channel 33. The valve body 3 is connected to the shaft body 1 so that it can rotate relative to each other. When the shaft body 1 drives the wheel body 2 to rotate, the valve body 3 does not rotate therewith because it is fixedly connected to the slitting device. After the valve body 3 is fixed on the mounting frame 6 of the slitting device, it is connected to the negative pressure suction device of the slitting device, so that the negative pressure suction device can extract the air in the suction channel 33. Since the wheel body 2 is located beside the valve body 3 and the suction channel 33 is connected to the air flow channel 22, the air in the suction channel 33 can be sucked out at the same time as the air in the air flow channel 22 of the wheel body 2 is extracted, so that the filter rod is adsorbed on the wheel body 2. In addition, when installed, the shaft body 1 can pass through the mounting frame 6 and be connected to the driving device on the slitting device, so that the driving device can drive the shaft body 1 to rotate, so that the wheel body 2 rotates with the shaft body 1, and then the filter rod is transferred.

[0066] The above-mentioned acceleration wheel can, after being installed on the slitting device, connect the air intake channel 33 in the valve body 3 with the negative pressure suction device on the slitting device, so that when the transmission shaft drives the acceleration wheel to rotate, the negative pressure suction device can suck out the air in the acceleration wheel through the air valve, so that the filter rod located in the clamping space 20 can be adsorbed on the clamping part 21, thereby improving the stability of the filter rod on the acceleration wheel.

[0067] In one embodiment, there are multiple air intake channels 33, and the multiple air intake channels 33 are arranged in a semi-circular shape inside half of the valve body 3. That is, the valve body 3 can be divided into a first valve body with a semi-circular structure and a second valve body with a semi-circular structure, and the multiple air intake channels 33 are all arranged around the shaft body 1 on the first valve body or the second valve body, and the axial direction of the air intake channels 33 is parallel to the axis of the shaft body 1. Specifically, the air intake channels 33 pass through the valve body 3 and are parallel to the axis of the shaft body 1. It is convenient for the valve body 3 to communicate with the external negative pressure suction device after installation. The semi-cylindrical inner hole of the first valve body and the semi-cylindrical inner hole of the second valve body are respectively matched with the outer cylindrical surface of the shaft body 1, and the first valve body and the second valve body are arranged oppositely and integrally formed. There are multiple air intake channels 33, and the multiple air intake channels 33 are evenly arranged on the first valve body or the second valve body with the shaft body 1 as the axis.

[0068] In the above-mentioned acceleration wheel, since the filter rod has the worst stability on the wheel body 2 when the filter rod rotates with the wheel body 2 to be located at the side and bottom of the wheel body 2, the wheel body 2 can be reinforced only when the filter rod is located at the side and bottom of the wheel body 2. That is, the wheel body 2 only needs to fix the filter rod in a half-circle path, so by centrally arranging the air intake channel 33 on one-half of the valve body 3, the air intake channel 33 is close to the side and bottom of the wheel body 2, which can reduce the processing amount while ensuring the fixing effect of the filter rod.

[0069] See also Figure 3 and Figure 5In one embodiment, along the axial direction of the shaft body 1, the two ends of the valve body 3 have a first side surface and a second side surface, respectively, an arc waist groove 34 is provided on the first side surface of the valve body 3, and an arc groove body 35 is provided on the second side surface of the valve body 3, and the two ends of the air intake channel 33 are respectively connected with the arc waist groove 34 and the arc groove body 35. Specifically, the arc waist groove 34 and the arc groove body 35 have the same shape, and the arc waist groove 34 and the arc groove body 35 are axially symmetrically arranged on the first side surface and the second side surface of the valve body 3. The arc waist groove 34 is provided on the first side surface of the valve body 3 and extends a certain distance inside the valve body 3, and the arc groove body 35 is provided on the second side surface of the valve body 3 and extends a certain distance inside the valve body 3. The air intake channel 33 is a circular channel. Compared with other shapes, the circular shape is easier to process and occupies less space, thereby effectively ensuring the firmness of the valve body 3 after drilling. The air intake channel 33 has an air inlet and an air outlet, and the air inlet and the air outlet are respectively connected to the arc-shaped waist groove 34 and the arc-shaped groove body 35. By arranging multiple circular air intake channels 33 between the arc-shaped waist groove 34 and the arc-shaped groove body 35, it is convenient to simultaneously draw external air into multiple air intake channels 33, and it is also convenient to simultaneously draw out the air inside multiple air intake channels 33. In addition, the center of the arc-shaped waist groove 34 and the center of the arc-shaped groove body 35 both coincide with the central axis of the shaft body 1. It is ensured that when the shaft body 1 drives the wheel body 2 to rotate relative to the valve body 3, the valve body 3 can better draw out the air inside the wheel body 2.

[0070] The above-mentioned acceleration wheel, through the setting of the arc-shaped waist groove 34, facilitates multiple suction channels 33 to be connected to the negative pressure suction device on the slitting device at the same time, and at the same time, through the setting of the arc-shaped waist groove 34, facilitates multiple suction channels 33 to be connected to the air flow channel 22 of the wheel body 2 at the same time.

[0071] In one embodiment, the valve body 3 includes a first connector 31 and a second connector 32, the second connector 32 is connected to the first connector 31, and the second connector 32 is located between the first connector 31 and the wheel body 2, and the outer diameter of the first connector 31 is greater than the outer diameter of the second connector 32. Specifically, the valve body 3 is a boss structure. The arc waist groove 34 is provided on the first side of the first connector 31, the arc groove body 35 is provided on the second side of the second connector 32, and the first side of the second connector 32 is connected to the second side of the first connector 31. A positioning hole 36 that passes through the first connector 31 is provided on the first side of the first connector 31, and the positioning holes 36 are all provided on the first connector 31 with the shaft body 1 as the axis. Through the positioning hole 36, the valve body 3 can be fixed to the mounting frame 6 of the slitting device by tools such as bolts.

[0072] The above-mentioned acceleration wheel can connect the valve body 3 with the wheel body 2 through the second connecting body 32, and connect the valve body 3 with the slitting device through the first connecting body 31. Therefore, when the outer diameter of the first connecting body 31 is larger than the outer diameter of the second connecting body 32, it can ensure that the contact area between the valve body 3 and the slitting device is larger and the connection effect is better.

[0073] See also Figure 1 and Figure 4 In one embodiment, the acceleration wheel further comprises an adjusting member 5, which is sleeved on the outer peripheral surface of the shaft body 1, and a through hole 51 is provided on the adjusting member 5, and the through hole 51 is communicated with the air intake channel 33. Specifically, the through hole 51 is a semi-circular hole, and the shape and size of the through hole 51 are consistent with the shape and size of the longitudinal section of the arc waist groove 34. The outer diameter of the adjusting member 5 is consistent with the outer diameter of the first connecting body 31. It is ensured that the size of the adjusting member 5 is adapted to the size of the first side surface of the first connecting body 31. The adjusting member 5 is provided with positioning openings 52 with the same number as the positioning holes 36, and the positioning openings 52 are all arranged on the adjusting member 5 with the shaft body 1 as the axis, and the positioning openings 52 are communicated with the positioning holes 36. So that the valve body 3 and the adjusting member 5 can be installed on the mounting frame 6 together by tools such as bolts. Among them, the adjusting member 5 can use gaskets. By using gaskets of different specifications and thicknesses, or by increasing or decreasing the number of gaskets, the gap between the valve body 3 and the slitting device can be changed, and then the gap between the valve body 3 and the wheel body 2 can be changed. While ensuring that the gap between the wheel body 2 and the valve body 3 does not affect the air suction requirement, it also ensures that the valve body 3 does not affect the normal rotation of the wheel body 2.

[0074] For the above-mentioned acceleration wheel, when the gap between the wheel body 2 and the valve body 3 is large, the air in the wheel body 2 is not easy to enter the valve body 3 and then be sucked out. When there is no gap between the wheel body 2 and the valve body 3, the wheel body 2 will rub against the valve body 3 during the rotation process, thereby affecting the rotation effect. Therefore, the gap between the valve body 3 and the wheel body 2 can be changed by the adjustment member 5, so that the gap will neither affect the air suction requirement nor affect the normal rotation of the wheel body 2.

[0075] In one embodiment, the valve body 3 is located between the adjusting member 5 and the wheel body 2. Specifically, the adjusting member 5 abuts against the first side surface of the valve body 3. The adjusting member 5 changes the gap between the valve body 3 and the wheel body 2, rather than the gap between the adjusting member 5 and the valve body 3 or between the adjusting member 5 and the wheel body 2. In addition, the adjusting member 5 can use a gasket made of soft material to enhance the friction between the valve body 3 and the slitting device.

[0076] The above-mentioned acceleration wheel makes it easier for the adjusting member 5 to adjust the gap between the valve body 3 and the wheel body 2 by locating the adjusting member 5 on the side of the valve body 3 away from the wheel body 2 .

[0077] See also Figure 6 and Figure 7In one embodiment, a plurality of clamping parts 21 are all arranged around the outer circumference of the wheel body 2 with the shaft body 1 as the axis, and a guide surface 211 and an arc surface 212 are provided on the clamping part 21, and the clamping space 20 is surrounded by the guide surface 211 and the arc surface 212. Specifically, two adjacent clamping parts 21 are connected end to end. That is, the second end of the guide surface 211 is connected to the first end of the arc surface 212, the first end of the guide surface 211 is connected to the second end of the arc surface 212 of the previous clamping part 21, and the second end of the arc surface 212 away from the guide surface 211 is connected to the first end of the guide surface 211 of the next clamping part 21. When the filter rod is transferred to the wheel body 2, the filter rod enters the inside of the arc surface 212 along the guide surface 211, and when the filter rod is transferred from the wheel body 2, the filter rod moves out along the second end of the arc surface 212.

[0078] The above-mentioned acceleration wheel can guide the filter rod into the arc surface 212 through the guide surface 211, so that the arc surface 212 limits the filter rod. Compared with the V-shaped groove used in the prior art, the arc surface 212 is more conducive to the wheel body 2 to transfer the filter rod, and it is also easier to make the filter rod fit with the clamping part 21, thereby ensuring the stability between the filter rod and the clamping part 21, and the filter rod is less likely to deform when being adsorbed.

[0079] In one embodiment, the airflow channel 22 includes a first air suction groove 221 and a second air suction groove 222, the first air suction groove 221 is arranged on the first side surface of the wheel body 2 around the shaft body 1, the second air suction groove 222 is arranged on the arc surface 212 of the clamping portion 21, and the second air suction groove 222 is connected with the first air suction groove 221. Specifically, the first air suction groove 221 is opened on the first side surface of the wheel body 2 and extends a certain distance into the wheel body 2, and the first air suction groove 221 is parallel to the shaft body 1. The second air suction groove 222 is opened on the arc surface 212 of the clamping portion 21 and extends a certain distance into the wheel body 2 until it is connected with the first air suction groove 221. The second air suction groove 222 is perpendicular to the shaft body 1. In addition, the distance between the central axis of the first air suction groove 221 and the shaft body 1 is consistent with the distance between the central axis of the air suction channel 33 and the shaft body 1. The air flow channel 22 can be aligned with the air intake channel 33, and the distance between the air flow channel 22 and the air intake channel 33 can be reduced to the greatest extent, thereby ensuring the air intake effect.

[0080] With the acceleration wheel, the air in the clamping space 20 can be sucked into the valve body 3 through the second suction groove 222 and the first suction groove 221 in sequence, so that the filter rod can be adsorbed and fixed in the clamping space 20 .

[0081] See also Figure 1 and Figure 8Another embodiment of the present invention provides a slitting device, including a mounting frame 6 and the above-mentioned acceleration wheel, the acceleration wheel is arranged on the mounting frame 6, and the shaft body 1 passes through the mounting frame 6, the mounting frame 6 is provided with a wheel group 7 and a negative pressure suction device, and the negative pressure suction device is connected with the wheel group 7 and the acceleration wheel. Specifically, the mounting frame 6 is a plate-shaped structure, the mounting frame 6 is provided with a driving mechanism, and the first end of the shaft body 1 passes through the mounting frame 6 and is in transmission connection with the driving mechanism. The first side surface of the adjusting member 5 abuts against the mounting frame 6, and the second side surface of the adjusting member 5 abuts against the first side surface of the valve body 3.
