Description

TECHNICAL FIELD

[0001] The present application relates to the field of tobacco rod forming technology, and particularly relates to a suction type rod conveying device. BACKGROUND

[0002] The term "tobacco industry rod" should be understood as an endless rod formed of tobacco or filter tow. In the production of smokeable articles, such as cigarettes, it is necessary to draw a mixture of cut tobacco and tobacco substitutes, usually in bulk, onto a circulating suction belt (for example, a permeable woven belt) to form a continuous tobacco rod moving in the direction of the longitudinal axis (longitudinal direction); after removing the excess tobacco, the tobacco rod is placed on a wrapping belt and wrapped, and the cigarette rod thus produced is cut into individual or multiple long cigarettes, which are then further processed. In this way, tobacco and tobacco substitutes can be used to produce rod-shaped smoking articles, such as cigarettes, small cigars, cigars, etc.

[0003] In the known machines, the rod guide channel and the suction belt form a downwardly open forming trough, and the negative pressure on the back of the suction belt draws the mixture of cut tobacco and tobacco substitutes into the forming trough in a suspended manner and transports it in the longitudinal direction, thereby forming a continuous tobacco rod, while the forwardly transported tobacco rod is subjected to a planarizer device to remove the excess tobacco and form a tobacco rod with a cross-sectional shape approximating a rectangle, and the width of the rectangular tobacco rod is determined by the width of the rod guide channel, and the width value is related to the diameter specification of the cigarette.

[0004] At present, cigarette processing machines all adopt the approach of covering a range of cigarette diameter specifications with one channel width specification. For example, the PROLAB cigarette making machine group of the German HAUNI company has three channel width specifications of 7mm, 8mm and 9mm, wherein the 7mm specification corresponds to a cigarette diameter of 5.4mm-6.59mm, the 8mm specification corresponds to a cigarette diameter of 6.6mm-7.9mm, and the 9mm specification corresponds to a cigarette diameter of 7.91mm-9.0mm.

[0005] When the cigarette diameter specification changes across the interval, the corresponding specification of the rod guide channel needs to be replaced, but when replacing the rod guide channel of different specifications, the following disadvantages exist:

[0006] 1. The replacement operation is labor-intensive and time-consuming, thereby affecting the production efficiency of the rod.

[0007] 2. The longitudinal axis of the rod guide channel is fixed (the downstream equipment receiving the rod is fixed), and when the rod guide channel is replaced, it is difficult to ensure the installation accuracy of the rod guide channel, and the installation position of the rod guide channel needs to be adjusted multiple times.

[0008] Therefore, how to improve the replacement efficiency and installation precision of the bundle guiding channel has become a technical problem to be solved by those skilled in the art. SUMMARY

[0063] For those skilled in the art, the suction-type bundle conveying device includes a wind chamber 200 and a bundle guiding channel 100. The wind chamber 200 is connected to a negative pressure fan via a pipe. The bundle guiding channel 100 is installed at the lower outlet position of the wind chamber 200 and typically consists of a suction channel section 121, a cleaver channel section 122, and a wing plate section 123. A circulating suction belt 110 passes below the bundle guiding channel and is supported by a series of horizontally arranged pulleys 140, and moves along the longitudinal axis (…). Figure 1 (Longitudinal direction) movement.

[0064] During operation, the negative pressure inside the air chamber 200 acts on the suction belt 110, adsorbing the tobacco shreds transported by the suction channel section 121 below the suction belt 110, forming a continuous bundle 300; after the leveling device removes excess tobacco shreds, the bundle 300 enters the downstream machine for wrapping.

[0065] Examples, such as Figures 1-10 As shown, a suction-type bundle conveying device with adjustable bundle width is disclosed. This device includes a bundle guide channel 100 and an air chamber 200. The bundle guide channel 100 is fixedly installed at the lower outlet position of the air chamber 200 and is used for forming and longitudinally conveying the bundle 300. The bundle guide channel 100 includes:

[0066] The suction belt 110 is arranged in the longitudinal direction.

[0067] Linear guide rail 120, there are two linear guide rails 120, and the two linear guide rails 120 are arranged side by side on both sides of the suction belt 110 in the longitudinal direction.

[0068] Adjustment mechanism 130, there are multiple adjustment mechanisms 130, and the multiple adjustment mechanisms 130 are linearly distributed in the longitudinal direction above the suction belt 110 and located between two linear guide rails 120.

[0069] The distance adjusting mechanism 130 is in transmission connection with the linear guides 120 on the two sides in the transverse direction and can drive the two linear guides 120 to move in the reverse direction at equal distances in the transverse direction.

[0070] The present application adopts the mode of adjusting the channel width, and the distance adjusting mechanism 130 is in transmission connection between the two linear guides 120 above the suction belt 110. The reverse movement at equal distances of the two linear guides 120 in the transverse direction can be driven by the distance adjusting mechanism 130, the adjustment and fixation of the width of the bundle strip guide channel 100 are quickly realized, the longitudinal axis of the bundle strip guide channel 100 is maintained unchanged, the replacement efficiency of the bundle strip guide channel 100 is improved, and the production efficiency of the bundle strip 300 is ensured.

[0071] It should be noted that the longitudinal direction in the present application is Figure 1 the single arrow direction in the formula, that is, the conveying direction of the bundle strip 300.

[0072] In a specific embodiment, as Figures 2-9 shown, the distance adjusting mechanism 130 includes a base 131, an adjusting block 132, an adjusting screw 133, a distance fixing bolt 134, and a support sleeve 135.

[0073] The base 131 is fixedly installed above the suction belt 110, and a longitudinal guide hole 1372 is arranged in the middle of the base 131 in the longitudinal direction, and a transverse mounting hole 1374 is arranged in the bottom of the base 131 in the transverse direction.

[0074] The adjusting block 132 includes a longitudinal guide section 1321 and a vertical adjusting section 1322, and the top end of the vertical adjusting section 1322 is vertically fixedly connected with one end of the longitudinal guide section 1321 in the transverse direction, so that the adjusting block 132 as a whole is L-shaped; the vertical adjusting section 1322 is arranged in the vertical direction and is inserted (embedded) in the insertion slot 124 between the two linear guides 120 (a plurality of insertion slots 124 are linearly distributed between the two linear guides 120 in the longitudinal direction, and the insertion slot 124 as a whole is isosceles trapezoidal); at the same time, distance adjusting inclined surfaces 1323 are symmetrically arranged on the transverse two sides of the vertical adjusting section 1322, and the distance adjusting inclined surfaces 1323 can be one-to-one correspondingly fitted with guide inclined surfaces (not shown in the figure) on the transverse two sides of the insertion slot 124; when the vertical adjusting section 1322 moves in the longitudinal direction, the two guide inclined surfaces can be driven to move in the transverse direction through the abutting fit of the distance adjusting inclined surfaces 1323 and the guide inclined surfaces, thereby realizing the adjustment of the transverse distance between the two linear guides 120.

[0075] The longitudinal guide hole 1372 comprises a guide segment and a connecting segment which are communicated in the longitudinal direction; the longitudinal guide segment 1321 is arranged in the longitudinal direction, and the other end of the longitudinal guide segment 1321 is movably inserted into the guide segment of the longitudinal guide hole 1372 for guiding the movement of the adjusting block 132; one end of the adjusting screw 133 is threadedly connected into the connecting segment of the longitudinal guide hole 1372 and abuts against the other end of the longitudinal guide segment 1321, so that the adjusting block 132 is driven to move in the longitudinal direction by the axial movement of the adjusting screw 133 in the longitudinal guide hole 1372, the abutting action of the adjusting screw 133 and the longitudinal guide segment 1321, and then the lateral spacing of the two linear guides 120 is adjusted.

[0076] The other linear guide 120 is provided with a stepped threaded hole comprising a through hole segment and a threaded segment which are communicated in the lateral direction; the support sleeve 135 is fixedly connected (coaxially) into the lateral mounting hole 1374, and one end of the support sleeve 135 is movably inserted into the guide hole segment of the avoiding hole and can axially reciprocate, and the other end of the support sleeve 135 is movably inserted into the through hole segment of the threaded hole and can axially reciprocate, so that the two ends of the support sleeve 135 are respectively connected with the two linear guides 120 in the lateral sliding manner.

[0077] The distance bolt 134 is arranged in the support sleeve 135, and the nut end of the distance bolt 134 extends to the outside of one linear guide 120 in the axial direction and abuts against the linear guide 120, and the screw end of the distance bolt 134 extends into the threaded hole of the other linear guide 120 in the axial direction and is threadedly connected with the linear guide 120, so that the two linear guides 120 are clamped and fixed to the adjusting block 132 through the abutting cooperation and threaded connection of the distance bolt 134 with the two linear guides 120, and the lateral spacing of the two linear guides 120 is fixed.

[0078] The beam guiding channel 100 is arranged in this way because the longitudinal axis of the beam guiding channel 100 needs to be fixed due to the limitation of the downstream device, and thus when the lateral spacing of the two linear guides 120 is adjusted, the two linear guides 120 need to be moved equidistantly in the lateral direction. In this embodiment, the adjusting block 132 is embedded between the two linear guides 120, and the distance adjusting inclined surfaces 1323 on the lateral sides of the adjusting block 132 are in contact with the guiding inclined surfaces on the linear guides 120. The adjusting block 132 can be driven to move longitudinally by rotating the adjusting screw 133, and then the two linear guides 120 are driven to move equidistantly in the opposite direction, so as to adjust the lateral spacing of the two linear guides 120. The support sleeve 135 is fixedly connected to the bottom of the base 131, and the two ends of the support sleeve 135 are in sliding connection with the two linear guides 120 in the lateral direction, so as to guide the two linear guides 120 in the lateral direction. The linear guides 120 can be supported and fixed in the vertical direction by the support of the support sleeve 135. The distance bolt 134 is penetrated through one linear guide 120 and is embedded in the support sleeve 135. The two linear guides 120 can be clamped and fixed to the adjusting block 132 by the threaded connection of the distance bolt 134 and the other linear guide 120, so as to fix the lateral spacing of the two linear guides 120.

[0079] Preferably, the guiding section of the longitudinal guiding hole 1372 is a square hole, and the connecting section is a threaded hole.

[0080] In a specific embodiment, as shown in Figure 5 , Figure 7As shown, the base 131 includes a connecting seat 136 and a supporting seat 137, the connecting seat 136 is arranged above the supporting seat 137 and detachably fixedly connected with the supporting seat 137; a transverse positioning surface 1361 for abutting with the wind chamber side wall 210 is arranged on a transverse side of the connecting seat 136, and after the transverse positioning surface 1361 abuts with the wind chamber side wall 210, the longitudinal axis of the distance adjusting mechanism 130 coincides with the longitudinal axis of the bundle strip guide channel 100, so as to ensure that the longitudinal axes of the two linear guides 120 remain unchanged after the two linear guides 120 are adjusted in transverse spacing by the adjusting block 132. A connecting lug 1363 is formed on the transverse positioning surface 1361 and extends in the transverse direction, the connecting lug 1363 is provided with a coaxial transverse threaded hole 1364, and a connecting bolt 230 matched with the transverse threaded hole 1364 is arranged on the wind chamber side wall 210, so that the distance adjusting mechanism 130 can be fixedly connected with the wind chamber side wall 210. That is, after the distance adjusting mechanism 130 is arranged on the wind chamber side wall 210, the central plane of the distance adjusting mechanism 130 coincides with the central plane of the bundle strip guide channel 100, and when the distance adjusting mechanism 130 adjusts the width of the bundle strip guide channel 100, the two linear guides 120 symmetrically expand to both sides or move towards the center relative to the central plane of the distance adjusting mechanism 130, so that the central plane of the bundle strip guide channel 100 is always aligned with the central plane of the known art cigarette rod forming guide rail downstream.

[0081] Preferably, as shown in the drawings, Figure 7 As shown, the connecting seat 136 is provided with a vertical connecting hole 1362, the vertical connecting hole 1362 includes an upper and lower circular hole section and a square hole section; a vertical insertion block 1371 is arranged on the top of the supporting seat 137, the vertical insertion block 1371 is inserted into the square hole section at the bottom of the vertical connecting hole 1362, and a fastening bolt 138 is arranged in the vertical connecting hole 1362, the bottom end of the fastening bolt 138 is threadedly connected with a threaded hole in the vertical insertion block 1371, so that the connecting seat 136 and the supporting seat 137 are detachably fixedly connected; a vertical supporting plate 1373 is arranged on the bottom of the supporting seat 137, a transverse mounting hole 1374 is arranged on the vertical supporting plate 1373, and the transverse dimension of the vertical supporting plate 1373 is smaller than the minimum spacing between the two linear guides 120, so as to increase the adjustment range of the transverse spacing of the two linear guides 120.

[0082] In a specific embodiment, as shown in the drawings, Figure 7 As shown, a dividing disc 1331 is fixedly connected to the end of the adjusting screw 133 away from the supporting seat 137 in the longitudinal direction, a plurality of dividing grooves 1332 are circumferentially and uniformly arranged on the dividing disc 1331, and a dividing pin 139 is detachably connected to one side of the supporting seat 137, the dividing pin 139 is arranged in the longitudinal direction and can be in abutting engagement with the dividing groove 1332 rotated to a predetermined position, so as to fix the rotating position of the dividing disc 1331.

[0083] Preferably, the number of the index grooves 1332 is 4-8.

[0084] In a specific embodiment, as shown in Figure 7 , Figure 8 the vertical adjustment section 1322 comprises a wedge-shaped block with isosceles trapezoidal cross section, and the wedge angle of the wedge-shaped block is a.

[0085] In a specific embodiment, as shown in Figure 3 in the transverse direction, the support sleeve 135 is symmetrically installed in the transverse mounting hole 1374, and the two ends of the support sleeve 135 are slidingly connected in the stepped holes of the two linear guides 120, while the axial length of the support sleeve 135 is greater than the minimum transverse distance between the two linear guides 120 and less than the maximum transverse distance between the two linear guides 120.

[0086] The reason for this arrangement is that in the prior art, the linear guide 120 comprises a silk suction channel section 121, a cleaver channel section 122 and a wing plate section 123 connected in sequence in the longitudinal direction; wherein the silk suction channel section 121 and the cleaver channel section 122 are both composed of a rail body 125, a T-shaped wear-resistant piece 127 and a fixed block 126, and the opposite side of the two rail bodies 125 is provided with a shoulder, the fixed block 126 is fixed on the shoulder of the rail body 125 by screws, the T-shaped wear-resistant piece 127 is fixedly connected between the fixed block 126 and the rail body 125, the suction belt 110 is arranged between the two T-shaped wear-resistant pieces 127, and the material of the T-shaped wear-resistant piece 127 is wear-resistant hard alloy and is fixed on the fixed blocks 126 on the left and right sides of the pulley 140 by adhesion; separating the linear guide 120 into a combination for separate processing can reduce the processing difficulty and improve the processing precision.

[0087] In the present embodiment, the guide hole section of the relief hole on the linear guide 120 is provided on the fixed block 126, and the perforated section is provided on the rail body 125; the light hole section of the threaded hole on the linear guide 120 is provided on the fixed block 126, and the threaded section is provided on the rail body 125. By setting the axial length of the support sleeve 135 to be less than the maximum distance between the two rail bodies 125 and greater than the minimum distance between the two rail bodies 125, when the two rail bodies 125 are sleeved on the support sleeve 135, the two ends of the support sleeve 135 will not interfere with the rail bodies 125 when the distance between the two rail bodies 125 is the smallest; when the distance between the two rail bodies 125 is the largest, the two ends of the support sleeve 135 are inserted into the two fixed blocks 126, thereby meeting the requirement of the transverse distance adjustment range of the two linear guides 120.

[0088] It should be noted that the distance adjustment mechanism 130 is linearly distributed on the silk suction channel section 121 and the cleaver channel section 122 in the longitudinal direction.

[0089] Embodiment, a method for adjusting the suction strip conveying device, the method uses the above-mentioned suction strip conveying device, the method comprises the following steps:

[0090] S10: loosen the fixed distance bolt 134, so that the two linear guides 120 can move laterally; that is, the fixing of the lateral spacing of the two linear guides 120 is released, so that the two linear guides 120 can slide on the support sleeve 135 in the lateral direction.

[0091] S20: rotate the adjusting screw 133 by N turns, adjust the lateral spacing of the two linear guides 120 by the longitudinal movement of the adjusting block 132; that is, by the axial movement of the adjusting screw 133, the adjusting block 132 is driven to move in the longitudinal direction by a predetermined distance, and by the abutting cooperation of the adjusting distance inclined surface 1323 on the adjusting block 132 and the guide inclined surface on the linear guide 120, the two linear guides 120 are driven to move in the lateral direction by an equal distance with the longitudinal axis as the center line.

[0092]

[0093] Wherein, L1 is the lateral spacing of the two linear guides 120 after adjustment; L2 is the lateral spacing of the two linear guides 120 before adjustment; S is the adjustment accuracy; n is the number of index grooves 1332 on the index plate 1331;

[0094]

[0095] Wherein, P is the pitch of the adjusting screw 133 mm; α is the included angle of the two adjusting distance inclined surfaces 1323.

[0096] For example: select the pitch P=0.5mm, the number of index grooves n=5, and the wedge angle α=90°, then the adjustment accuracy is 0.2mm.

[0097] Specifically: when adjusting the width of the strip guide channel 100, as the adjusting screw 133 is screwed in, the adjusting screw 133 will drive the adjusting block 132 to extend in the longitudinal direction, and under the support and guidance of the support sleeve 135, the two linear guides 120 will be spread to the lateral sides at equal intervals relative to the adjusting block 132, and the width of the strip guide channel 100 will increase; on the contrary, as the adjusting screw 133 is unscrewed, the adjusting screw 133 will drive the adjusting block 132 to retract in the longitudinal direction, and under the locking action of the fixed distance bolt 134, the two linear guides 120 will be contracted to the lateral sides at equal intervals relative to the adjusting block 132, and the width of the strip guide channel 100 will decrease.

[0098] S30: replace the suction belt 110 of the required size.

[0099] S40: the distance bolt 134 is screwed to make the two linear guide rails 120 move laterally and clamp the adjusting block 132, that is, the lateral spacing of the two linear guide rails 120 is fixed.
