[0002] The filter rod is the predecessor of the filter, and the formed filter rod can form a plurality of filters by shearing. Before shearing, the burst port quality defect of the filter rod needs to be detected. The traditional detection method is to hold the two ends of the filter rod with two hands respectively, and rotate 90 degrees in the opposite direction. If the filter rod bursts at the joint, it is considered that the filter rod has a burst port quality defect. This method is a manual operation, and the error is large, so it is difficult to accurately compare the quality differences between various filter rods.

[0003] The filter rod burst port detector in the related art uses two torque motors to simulate the manual twisting of the detection personnel to detect the burst port of the filter rod wrapping paper, so that the torsion of each filter rod is uniform. However, for a hollow transparent filter rod formed by a plurality of acetate fiber rod segments arranged at intervals along the axial direction of the filter rod and wrapped by transparent forming paper, since there is a transparent window segment between the two adjacent acetate fiber rod segments, when detected by the traditional reverse twisting detection method, the transparent window segment is severely twisted and deformed, which seriously affects the detection of the filter rod burst port.

[0044] The present embodiment provides a hollow transparent filter rod burst port detection device, the hollow transparent filter rod is composed of multiple acetate fiber segments arranged at intervals wrapped by transparent formed paper, there is a transparent window segment between the two adjacent acetate fiber segments, as shown in Figures 1-3 The hollow transparent filter rod burst port detection device includes a rubbing base 1, an inner size adjusting unit 2, and a rubbing cover plate 3. Along the length direction of the rubbing base 1, the cross section of the rubbing base 1 is U-shaped to form a three-opened cavity 11 for placing the hollow transparent filter rod. The inner size adjusting unit 2 includes a height adjusting assembly 21 and a first support 22. The height adjusting assembly 21 is arranged on the inner wall of the cavity 11, and the output end of the height adjusting assembly 21 is in transmission connection with the first support 22. The first support 22 extends along the length direction of the rubbing base 1. The height adjusting assembly 21 can drive the first support 22 to move along the height direction of the rubbing base 1. The rubbing cover plate 3 is slidably connected to the first support 22 along the length direction of the rubbing base 1, and one side of the rubbing cover plate 3 facing the cavity 11 can contact the hollow transparent filter rod.

[0045] When detecting bursts, the hollow transparent filter rod to be tested is placed into the cavity 11 of the rubbing base 1. Then, the height adjustment component 21 drives the first support member 22 to move upward until the distance between the upper end face of the first support member 22 and the bottom wall of the cavity 11 along the height direction of the rubbing base 1 is equal to the diameter of the hollow transparent filter rod. Then, the rubbing cover plate 3 is placed on the first support member 22 and pushed to slide back and forth once along the length direction of the rubbing base 1. The side of the rubbing cover plate 3 facing the cavity 11 contacts the outer surface of the hollow transparent filter rod, forming a stable detection state of bottom support and top pressing. By setting the rubbing base 1, the inner size adjustment unit 2 and the rubbing cover plate 3, the two ends of the hollow transparent filter rod rotate in the same direction when the burst detection is performed. There will be no torque in opposite directions at the two ends, which protects the transparent window section from the source and avoids torsional deformation of the transparent window section, thus improving the stability of the burst detection of the hollow transparent filter rod. It should be noted that the length of the splicing base 1 is 395mm-405mm, the height is 145mm-155mm, and the width is 25mm-35mm. In this embodiment, the preferred height of the splicing base 1 is 400mm, the preferred width is 150mm, and the preferred height is 30mm. In other embodiments, the height of the splicing base 1 is 398mm or 403mm, the width of the splicing base 1 is 147mm or 155mm, and the height of the splicing base 1 is 25mm or 35mm, etc. No limitations are imposed here.

[0046] Specifically, in this embodiment, both the joint base 1 and the joint cover plate 3 are made of stainless steel. In other embodiments, both the joint base 1 and the joint cover plate 3 are made of aluminum alloy, both are made of acrylic, or the joint base 1 is made of aluminum alloy and the joint cover plate 3 is made of acrylic, etc. No limitations are imposed here.

[0047] Optionally, such as Figure 1 As shown, in this embodiment, the bottom wall of the cavity 11 is provided with an anti-slip layer, and the hollow transparent filter rod is placed on the anti-slip layer. The anti-slip layer ensures that when the rubbing cover plate 3 slides back and forth along the length direction of the rubbing base 1, the hollow transparent filter rod in contact with it only rolls, avoiding slippage, which helps to improve the reliability and stability of the hollow transparent filter rod burst detection.

[0048] Specifically, in this embodiment, the anti-slip layer is an anti-slip coating. In other embodiments, the anti-slip layer is a thin silicone pad or a thin rubber pad, etc. No limitations are imposed here.

[0049] Optionally, in the embodiment, the first support 22 has an adjustable height of 5-8 mm, which can be 5 mm, 6 mm, 7 mm or 8 mm. In the embodiment, the adjustable height of the first support 22 is preferably 5 mm. In other embodiments, the adjustable height of the first support 22 can be 6 mm, 7 mm or 8 mm, etc. This is not limited here. It should be noted that the first support 22 is a first support plate, a first support frame or a first support block, etc. This is not limited here. Specifically, 5-8 mm covers the diameters of common thin, medium and regular cigarette rods on the market.

[0050] Optionally, as shown in Figure 2 , the height adjusting assembly 21 comprises a first height adjusting member 211, a second height adjusting member 212 and a driving member 213. The first height adjusting member 211 slides along the length direction of the rolling base 1, the second height adjusting member 212 slides along the length direction of the rolling base 1 and is opposite to the sliding direction of the first height adjusting member 211, and the driving member 213 is connected with the first height adjusting member 211 and the second height adjusting member 212 through the transmission assembly 4. The driving member 213 can drive the first height adjusting member 211 and the second height adjusting member 212 to move close to or away from each other to adjust the height of the first support 22. The first height adjusting member 211 and the second height adjusting member 212 are both slidingly connected with the first support 22.

[0051] When adjusting the height of the first support 22, the driving member 213 is started to transmit power to the transmission assembly 4. After receiving the power, the transmission assembly 4 converts it into two driving forces in opposite directions, which act on the first height adjusting member 211 and the second height adjusting member 212 respectively, so that the first height adjusting member 211 and the second height adjusting member 212 move in opposite directions along the length direction of the rolling base 1, thereby adjusting the height of the first support 22. By moving the two height adjusting members in opposite directions to change the height, the hollow transparent filter rod burst detection of different diameters is realized, and the versatility and adaptability of the hollow transparent filter rod burst detection device are improved.

[0052] Specifically, as shown in Figure 2 , the first height adjusting member 211 is a first wedge-shaped block, and the second height adjusting member 212 is a second wedge-shaped block. The first wedge-shaped block and the second wedge-shaped block have the same structure, and the wedge-shaped ends of the first wedge-shaped block and the second wedge-shaped block are arranged facing each other or away from each other. The same structure of the first wedge-shaped block and the second wedge-shaped block makes the lifting of the first support 22 synchronous when adjusting the height of the first support 22, and ensures the adjustment stability and precision of the first support 22.

[0053] Further specifically, as shown in Figure 2As shown, in the embodiment, the wedge-shaped ends of the first wedge-shaped block and the second wedge-shaped block are arranged opposite to each other, and the first support 22 is provided with a first inclined groove 221 and a second inclined groove 222 arranged at intervals on one side of the first support 22 facing the first wedge-shaped block. Along the width direction of the rubbing base 1, the cross sections of the first inclined groove 221 and the second inclined groove 222 are both triangular, and the top end of the first wedge-shaped block can be accommodated in the first inclined groove 221, the top end of the second wedge-shaped block can be accommodated in the second inclined groove 222, and the side of the first wedge-shaped block away from the second wedge-shaped block can abut against the inner side wall of the first inclined groove 221, and the side of the second wedge-shaped block away from the first wedge-shaped block can abut against the inner side wall of the second inclined groove 222.

[0054] When the side of the first wedge-shaped block away from the second wedge-shaped block can abut against the inner side wall of the first inclined groove 221, and the side of the second wedge-shaped block away from the first wedge-shaped block can abut against the inner side wall of the second inclined groove 222, the height of the first support 22 is the lowest, and the height of the first support 22 is 5 mm. When it is necessary to adjust the height of the first support 22, the driving member 213 is started, and the first wedge-shaped block and the second wedge-shaped block are driven to slide towards each other by the transmission assembly 4. Since the wedge-shaped ends of the first wedge-shaped block and the second wedge-shaped block are arranged opposite to each other, the first support 22 is also raised. The above-mentioned structure is simple and can provide stable support force, and the triangular groove design can ensure that the wedge-shaped blocks always maintain a stable contact state during adjustment, thereby effectively improving the stability of the height adjustment of the hollow transparent filter rod burst detection device.

[0055] Further specifically, in the embodiment, the side of the first height adjusting member 211 opposite to the bottom wall of the cavity 11 is recessed with a first guide groove, and correspondingly, the bottom wall of the cavity 11 is provided with a first guide protrusion, the first guide groove and the first guide protrusion are in sliding connection, the side of the second height adjusting member 212 opposite to the bottom wall of the cavity 11 is recessed with a second guide groove, and correspondingly, the bottom wall of the cavity 11 is provided with a second guide protrusion, the second guide groove and the second guide protrusion are in sliding connection. The provision of the guide groove and the guide protrusion provides a guiding effect for the sliding of the first height adjusting member 211 and the second height adjusting member 212, thereby avoiding the transverse deviation of the first height adjusting member 211 and the second height adjusting member 212. In other embodiments, the side of the first height adjusting member 211 opposite to the bottom wall of the cavity 11 is provided with a first guide protrusion, and correspondingly, the bottom wall of the cavity 11 is provided with a first guide groove, the first guide groove and the first guide protrusion are in sliding connection, the side of the second height adjusting member 212 opposite to the bottom wall of the cavity 11 is provided with a second guide protrusion, and correspondingly, the bottom wall of the cavity 11 is provided with a second guide groove, the second guide groove and the second guide protrusion are in sliding connection.

[0059] When adjusting the height of the first support 22, the driving member 213 is started, the rotation of the driving member 213 directly drives the transmission gear 41 to rotate synchronously about its rotation axis on the rubbing base 1, when the transmission gear 41 rotates, the two transmission racks 42 on the two sides move synchronously and reversely linearly along the width direction of the rubbing base 1, then the power is transferred to the two connecting rods 43, and then the first height adjusting member 211 and the second height adjusting member 212 form reverse synchronous movement, thereby realizing the height adjustment of the first support 22, after the adjustment is completed, the locking rod is rotated to clamp one end of the locking rod at the meshing position of the transmission gear 41 and the transmission rack 42, that is, the locking rod is embedded in the gap between the teeth of the transmission gear 41 and the teeth of the transmission rack 42, after clamping, the teeth of the transmission gear 41 and the teeth of the transmission rack 42 are clamped by the locking rod and cannot rotate relatively, thereby locking the relative movement of the transmission gear 41 and the transmission rack 42, indirectly fixing the positions of the first height adjusting member 211 and the second height adjusting member 212, and at the same time ensuring the height of the first support 22. The transmission assembly 4 realizes the transmission of power.

It should be noted that the second support 24 is a second support plate, a second support frame or a second support block, etc. This is not limited here.

The above arrangement can limit the movement of the crimping cover plate 3 along the width direction of the crimping base 1 when the crimping cover plate 3 slides on the first support 22, thereby avoiding the transparent window segment of the hollow transparent filter rod from being twisted due to the force in other directions during the detection of the burst of the hollow transparent filter rod, and further affecting the detection of the burst of the hollow transparent filter rod.

[0069] The embodiment also provides a method for detecting the burst of a hollow transparent filter rod, which is applied to the device for detecting the burst of a hollow transparent filter rod. The method comprises the following steps: S1: placing the hollow transparent filter rod in the cavity 11, and adjusting the height adjusting assembly 21 so that the distance between the upper end face of the first support 22 and the bottom wall of the cavity 11 along the height direction of the crimping base 1 is equal to the diameter of the hollow transparent filter rod; S2: placing the crimping cover plate 3 on the first support 22 so that the face of the crimping cover plate 3 facing the cavity 11 is in contact with the hollow transparent filter rod; and S3: reciprocally sliding the crimping cover plate 3 on the first support 22 along the length direction of the crimping base 1 once. The above method can make the two ends of the hollow transparent filter rod rotate in the same direction during the detection of the burst, and the two ends of the hollow transparent filter rod will not have a torque in the opposite direction, thereby protecting the transparent window segment from the root, avoiding the transparent window segment from being twisted and deformed, and improving the detection stability of the hollow transparent filter rod.

[0070] Optionally, in step S3, the sliding speed of the crimping cover plate 3 is 50-200 mm / s.
