Description

Technical Field

[0001] The utility model relates to the technical field of tobacco shred processing, in particular to a tobacco shred thinning device. Background Art

[0002] During the tobacco production process, some debris from the tobacco leaves enters the cutter along with the tobacco. This results in the tobacco being mixed with non-tobacco debris. These small, numerous, and diverse debris reduce the purity of the tobacco and, in turn, affect the quality of the cigarettes. Therefore, in the back-end process of the cutter, operators initially relied on manual inspection to identify these debris. This not only caused visual fatigue and was ineffective over time, but also resulted in high labor intensity and the possibility of missed inspections.

[0003] At present, in order to solve the hidden danger of non-tobacco debris mixed in cut tobacco and reduce the intensity of manual labor, the existing technology is to install an online non-tobacco debris identification and removal system for tobacco above the belt conveyor behind the vibrating conveyor connected to the cutter. By installing an industrial CCD camera and establishing a dynamic monitoring imaging system for non-tobacco debris based on machine vision and AI technology, images of the tobacco surface during movement are collected to achieve online intelligent identification of cut tobacco.

[0004] However, after the tobacco leaves are cut into shreds by the cutter, when the tobacco leaves fall onto the belt conveyor via the vibrating conveyor connected to the cutter, most of the tobacco leaves are concentrated in the middle of the belt conveyor, which indirectly makes the tobacco stacking thickness on the belt conveyor thicker. When debris is mixed inside the thicker stack of tobacco leaves or at the bottom of the thicker stack of tobacco leaves, the non-tobacco debris dynamic monitoring imaging system cannot identify the debris and cannot remind the operator to remove it in time, resulting in the debris flowing into the subsequent tobacco processing steps, thereby reducing the quality of the tobacco products.

[0005] Therefore, it is necessary to guide the tobacco in the process of falling from the vibrating conveyor connected to the cutter to the belt conveyor, so as to solve the problem that when the tobacco falls on the belt conveyor through the vibrating conveyor, the tobacco falling on the belt conveyor is concentrated and the thickness of the tobacco is large, so the non-tobacco debris dynamic monitoring imaging system installed above the belt conveyor cannot identify the debris in the tobacco. Utility Model Content

[0006] The purpose of the utility model is to provide a tobacco thinning device to solve the problem that when tobacco falls onto a belt conveyor via a vibrating conveyor, the tobacco falling on the belt conveyor is concentrated and thick, so that a non-tobacco debris dynamic monitoring imaging system installed above the belt conveyor cannot identify debris in the tobacco.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] support rods;

[0010] A plurality of tobacco spreading plate mounting adjustable parts are provided, and the support rods are adjustably connected to the plurality of tobacco spreading plate mounting adjustable parts, respectively, with intervals being left between adjacent tobacco spreading plate mounting adjustable parts;

[0011] The tobacco spreading plates are each provided with an adjustable part which is detachably connected to the tobacco spreading plates. A channel for the tobacco to fall is defined between two adjacent tobacco spreading plates. The plurality of tobacco spreading plates are distributed in a fan-like manner.

[0012] Furthermore, the adjustable part for installing the tobacco spreading plate includes a first half clamp part, a second half clamp part and an adjusting part; the first half clamp part and the second half clamp part are spliced together to define a socket through hole for socketing the support rod, and the first half clamp part and the second half clamp part are respectively detachably connected to the tobacco spreading plate through the adjusting part.

[0013] Furthermore, the first half clamp and the second half clamp are half clamps of the same structure.

[0014] Furthermore, the half clamp comprises an L-shaped clamping seat and a sleeve semicircular hole. A sleeve semicircular hole is opened in the middle of the L-shaped clamping seat. The sleeve semicircular holes in the middle of the two L-shaped clamping seats are spliced to form a sleeve through hole for the sleeve support rod.

[0015] Furthermore, the adjusting member is an adjustable screw assembly, and the first threaded through holes on the two L-shaped clamping seat cross arms are threadedly connected to the second threaded through holes on the tobacco spreading plate through the adjustable screw assembly.

[0016] Furthermore, at least two first threaded through holes are provided along the cross arm of the L-shaped card seat.

[0017] Furthermore, at least four second threaded through holes are provided along the tobacco spreading plate.

[0018] Furthermore, the tobacco spreading plate is made of any one of a stainless steel metal plate or a stainless steel metal sheet.

[0019] During the working process, one end of the support rod is installed on the inner wall of the junction of the discharge end of the vibrating conveyor and the feed end of the belt conveyor, and several tobacco spreading plates distributed in a fan-shaped manner in the tobacco thinning device are located between the discharge end of the vibrating conveyor and the feed end of the belt conveyor to complete the installation process of the tobacco thinning device; when the tobacco falls from the discharge end of the vibrating conveyor onto the belt conveyor, the tobacco falling from the discharge end of the vibrating conveyor first falls on several tobacco spreading plates, and since several tobacco spreading plates are distributed in a fan-shaped manner, The cloth, and the channel for tobacco to fall is defined between two adjacent tobacco spreading plates, so that the tobacco slides along the descending tobacco spreading plates in sequence and falls on most areas of the belt conveyor, so that the tobacco falling on the belt conveyor is more dispersed and the thickness of the tobacco stacking is appropriate, avoiding the situation in which, when there is no tobacco thinning device, the falling tobacco is concentrated in the middle of the belt conveyor, resulting in a very thick distribution of tobacco, which is not conducive to the non-tobacco debris dynamic monitoring imaging system installed above the belt conveyor to identify debris.

[0021] 1. The utility model is provided with a plurality of tobacco spreading plates distributed downward in a fan shape between the connection point of the discharge end of the vibrating conveyor and the feed end of the belt conveyor. When the tobacco on the vibrating conveyor falls onto the belt conveyor, the plurality of tobacco spreading plates located between the tobacco on the vibrating conveyor and the belt conveyor will guide the fallen tobacco, and the tobacco will fall onto the belt conveyor from the tobacco falling channels between the tobacco spreading plates in different areas, so that the tobacco fallen on the belt conveyor is more dispersed, which is conducive to the process of identifying debris by the dynamic monitoring imaging system of non-tobacco debris installed above the belt conveyor, so as to solve the problem that when the tobacco falls onto the belt conveyor via the vibrating conveyor, the tobacco fallen on the belt conveyor is concentratedly distributed and the tobacco is relatively thick, so that the dynamic monitoring imaging system of non-tobacco debris installed above the belt conveyor cannot identify debris in the tobacco.

DETAILED DESCRIPTION

[0032] like Figure 1-8 In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] Example

[0034] After the tobacco leaves are cut into shreds by the cutter, the tobacco leaves fall onto the belt conveyor through the vibrating conveyor connected to the cutter. Most of the tobacco leaves are concentrated in the middle of the belt conveyor, which indirectly makes the tobacco stack on the belt conveyor thicker. When debris is mixed in the thicker stack of tobacco leaves or at the bottom of the thicker stack of tobacco leaves, the non-tobacco debris dynamic monitoring imaging system cannot identify the debris and cannot remind the operator to remove it in time, resulting in the debris flowing into the subsequent tobacco processing steps, thereby reducing the quality of the tobacco products.

[0035] Therefore, this application proposes a tobacco thinning device to solve the problem that when tobacco falls onto a belt conveyor via a vibrating conveyor, the tobacco falling on the belt conveyor is concentrated and thick, making it impossible for the non-tobacco debris dynamic monitoring imaging system installed above the belt conveyor to identify debris in the tobacco.

[0036] For details, please refer to Figure 1 、 Figure 2 and Figure 8 A tobacco thinning device comprises a support rod 1, several tobacco spreading plate mounting adjustable parts 2 and tobacco spreading plates 3; the support rod 1 is adjustably connected to several tobacco spreading plate mounting adjustable parts 2, and a gap is left between adjacent tobacco spreading plate mounting adjustable parts 2; each tobacco spreading plate mounting adjustable part 2 is detachably connected to each tobacco spreading plate 3, and a channel 4 for tobacco to fall is defined between two adjacent tobacco spreading plates 3, and several tobacco spreading plates 3 are distributed downward in a fan-like manner.

[0037] In actual use, one end of the support rod 1 is installed on the inner wall of the junction of the discharge end of the vibrating conveyor and the feed end of the belt conveyor, and the tobacco thinning device is provided with a plurality of tobacco spreading plates 3 that are distributed in a fan-shaped manner between the discharge end of the vibrating conveyor and the feed end of the belt conveyor to complete the installation process of the tobacco thinning device; when the tobacco falls from the discharge end of the vibrating conveyor onto the belt conveyor, the tobacco falling from the discharge end of the vibrating conveyor first falls on the plurality of tobacco spreading plates 3, and since the plurality of tobacco spreading plates 3 are fan-shaped, the tobacco thinning device is provided with a plurality of tobacco spreading plates 3 that are distributed in a fan-shaped manner. The tobacco is distributed in a fan-shaped descending manner, and a channel 4 for the tobacco to fall is defined between two adjacent tobacco spreading plates. The tobacco slides down along the several tobacco spreading plates 3 that are distributed in a fan-shaped descending manner and falls on most areas of the belt conveyor in sequence, so that the tobacco falling on the belt conveyor is more dispersed, and avoids the situation in which, when there is no tobacco thinning device, the falling tobacco is concentrated in the middle of the belt conveyor, resulting in a very thick distribution of tobacco, which is not conducive to the non-tobacco debris dynamic monitoring imaging system installed above the belt conveyor to identify debris in the tobacco.

[0038] See also Figure 1 and Figure 3 The tobacco spreading plate installation adjustable part 2 for adjusting the inclination angle of the tobacco spreading plate 3 or adjusting the interval between two adjacent tobacco spreading plates 3 includes a first half clamp part 5, a second half clamp part 6 and an adjusting part 7; wherein, the first half clamp part 5 and the second half clamp part 6 are used to be sleeved on the support rod 1 on the one hand; the adjusting part 7 is used to adjust and fix the posture of the first half clamp part 5 and the second half clamp part 6 sleeved on the support rod 1, thereby indirectly completing the adjustment process of the inclination angle of the tobacco spreading plate 3.

[0039] Specifically, the first half clamp 5 and the second half clamp 6 are symmetrically spliced to define a sleeve through hole 8 for sleeve connection of the support rod. The first half clamp 5 and the second half clamp 6 are detachably connected to the tobacco spreading plate 3 through the adjustment member 7 respectively.

[0040] In actual use, when adjusting the inclination angle of the tobacco spreading plate 3, first loosen the adjusting piece 7 so that the adjusting piece 7 and the first clamp half hoop 5, the second clamp half 6 and the tobacco spreading plate 3 are in an active connection state, but the first clamp half hoop 5 and the second clamp half 6 are movably connected to the support rod 1, and then according to the required inclination angle of the tobacco spreading plate 3 relative to the support rod 1, the first half clamp 5 and the second half clamp 6 are adjusted to the corresponding inclination angle respectively, and then the first half clamp 5, the second half clamp 6 and the tobacco spreading plate 3 are connected with the adjusting piece 7 to fix the first half clamp 5 and the second half clamp 6 with the adjusted inclination angle, thereby indirectly completing the process of adjusting the inclination angle of the tobacco spreading plate 3.

[0041] When adjusting the spacing between two adjacent tobacco spreading plates 3, first loosen the adjusting piece 7 on the adjustable mounting piece 2 of the two adjacent tobacco spreading plates 3 so that the adjusting piece 7 and the first clamping half hoop 5, the second half hoop 6 and the tobacco spreading plates 3 are in an active connection state, but the first clamping half hoop 5 and the second half hoop 6 are movably connected to the support rod 1, and then according to the spacing that needs to be adjusted between the two tobacco spreading plates 3, move the first clamping half hoop 5 and the second half hoop 6 on the adjustable mounting piece 2 of the two adjacent tobacco spreading plates 3 to the corresponding distance along the support rod 1, and then use the adjusting piece 1 on the adjustable mounting piece 2 of the two tobacco spreading plates 3 to connect the first clamping half hoop 5, the second half hoop 6, the support rod 1 and the tobacco spreading plates 3 on the adjustable mounting piece 2 of the two tobacco spreading plates 3, so as to fix the adjustable mounting piece 2 of the tobacco spreading plates with the adjusted spacing, and indirectly complete the process of adjusting the spacing between the two tobacco spreading plates 3.

[0042] In this way, by adjustably connecting several tobacco spreading plate mounting adjustable parts 2 to the support rod 1, and detachably connecting the tobacco spreading plate mounting adjustable parts 2 to each tobacco spreading plate 3, when guiding the tobacco, the inclination angle of the tobacco spreading plate mounting adjustable parts 2 and the interval between adjacent tobacco spreading plate mounting adjustable parts 2 can be adjusted according to the actual working conditions of the tobacco diversion, and the inclination angle of each tobacco spreading plate 3 and the interval between adjacent tobacco spreading plates 3 can be indirectly adjusted, so that the tobacco falling on the tobacco spreading plate can be guided faster or slower, thereby further improving the practicality of the tobacco thinning device.

[0043] It should be noted that, in order to prevent the tobacco spreading plate 3 from rusting, the tobacco spreading plate 3 is made of a stainless steel metal plate or a stainless steel metal sheet, thereby extending the service life of the tobacco spreading plate 3.

[0044] See also Figure 1 、 Figure 3 、 Figure 4 and Figure 5The first half clamp 5 and the second half clamp 6 used to be sleeved with the support rod 1 are half clamps with the same structure. The half clamps include an L-shaped clamping seat 9 and a sleeve semicircular hole 10; wherein, the L-shaped clamping seat 9 is used to be detachably connected to the tobacco spreading plate 3 on the one hand, and on the other hand cooperates with the sleeve semicircular hole 10 to complete the process of sleeved with the support rod 1.

[0045] Specifically, a sleeve semicircular hole 10 is opened in the middle of the L-shaped clamping seat 9, and the sleeve semicircular holes 10 in the middle of the two L-shaped clamping seats 9 are spliced to form a sleeve through hole 8 for the sleeve support rod 1. The two L-shaped clamping seats 9 cross arms are detachably connected to the tobacco spreading plate 3 through the adjustment parts 7.

[0046] In actual use, when the support rod 1 is socketed with the first half clamp 5 and the second half clamp 6, the support rod 1 can be inserted into the socket through hole 8 for socketing the support rod 1 formed by splicing the socket semicircular holes 10 in the middle of the two L-shaped clamping seats 9, and then the L-shaped clamping seat 9 is connected to the tobacco spreading plate 3 with the adjusting member 7, so that the two L-shaped clamping seats 9 and the support rod 1 are in a fixed connection, completing the process of socketing the first half clamp 5, the second half clamp 6 and the support rod 1.

[0047] See also Figure 5 、 Figure 6 and Figure 7 The adjusting member 7 used to realize the detachable connection between the horizontal arm of the L-shaped clamping seat 9 and the tobacco spreading plate 1 is an adjustable screw assembly. Specifically, the first threaded through holes 11 on the horizontal arms of the two L-shaped clamping seats 9 are threadedly connected to the second threaded through holes 12 on the tobacco spreading plate 3 through the adjustable screw assembly.

[0048] In actual use, when the cross arm of the L-shaped clamping seat 9 is assembled with the tobacco spreading plate 1 or the L-shaped clamping seat 9 with the tilt angle adjusted is fixed, the adjustable screw assembly can be threadedly connected to the first threaded through hole 11 on the cross arm of the L-shaped clamping seat 9 and the second threaded through hole 12 on the tobacco spreading plate 3 at the same time, and the cross arm of the L-shaped clamping seat 9 and the tobacco spreading plate 1 are in a relatively fixed state.

[0049] It should be noted that in order to improve the stability of the connection between the horizontal arm of the L-shaped clamping seat 9 and the tobacco spreading plate 1, at least two first threaded through holes 11 are opened along the horizontal arm of the L-shaped clamping seat 9, and at least four second threaded through holes 12 are opened along the tobacco spreading plate 3.

[0050] The present application provides a number of tobacco spreading plates that are distributed in a fan-shaped downward direction between the connection point of the vibrating conveyor discharge end and the belt conveyor feed end. When the tobacco on the vibrating conveyor falls onto the belt conveyor, the several tobacco spreading plates located between the tobacco on the vibrating conveyor and the belt conveyor will guide the fallen tobacco, and the tobacco will fall onto the belt conveyor from the tobacco falling channels between the tobacco spreading plates in different areas, making the tobacco falling on the belt conveyor more dispersed, thereby facilitating the process of identifying debris by the non-tobacco debris dynamic monitoring imaging system installed above the belt conveyor.
