Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a rubbing plate for a cigarette-rubbing device in a cigarette-loading machine. Background Technology

[0002] The cigarette-making process involves wrapping the tipping paper, filter, and cigarette into a filter cigarette of double the length. The working principle is as follows: when the joining drum receives the cigarette pack with the tipping paper attached from the drum near the drum, the suction in the cigarette receiving groove of the joining drum causes the cigarette pack to fall into the receiving groove. At the same time, the air holes on the outer surface of the joining drum lay the tipping paper flat on the outer surface.

[0003] When entering the jointing position, since the distance between the rubbing board and the jointing drum's tobacco receiving groove is the cigarette diameter minus 0.7mm, the rubbing board will inevitably carry the cigarette assembly out of the receiving groove and make the cigarette assembly roll between the outer surface of the jointing drum and the rubbing board, so that the tipping paper tightly wraps and bonds the cigarette assembly to form a double-length filter cigarette. The double-length filter cigarette, after being formed, finally enters the next process with the assistance of the return drum.

[0004] In this process, the structural design of the rubbing plate has a significant impact on the quality of cigarette splicing. In existing technology, the side of the rubbing plate near the rubbing drum has an arc-shaped rubbing surface corresponding to the outer circular surface contour of the rubbing drum. When the rubbing drum rotates at high speed and the rubbing plate carries the cigarette pack out of the cigarette receiving groove, the tipping paper on the cigarette pack is prone to folding at the overlap between the tipping paper and the cigarette pack at the moment of contact with the rubbing plate, which affects the splicing quality and thus the quality of cigarette production. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the prior art by providing a rubbing plate for a cigarette-rubbing device in a cigarette-loading machine. This prevents the cork paper on the cigarette pack from coming into contact with the rubbing plate and causing folds when the rubbing plate pulls the cigarette pack out of the cigarette receiving groove, thereby ensuring the quality of the cigarette-rubbing process and thus ensuring the production quality of the cigarette.

[0006] This utility model proposes a rubbing plate for a cigarette-rubbing device in a cigarette-loading machine, including a rubbing plate body and an arc-shaped rubbing surface disposed on one side of the rubbing plate body. The cigarette pack rolls in from one end of the arc-shaped rubbing surface and rolls out from the opposite end of the arc-shaped rubbing surface. The arc-shaped rubbing surface has a strip groove near the end where the cigarette pack rolls in. The strip groove extends laterally on the arc-shaped rubbing surface and corresponds to the position of the tipping paper in the cigarette pack, so as to avoid the tipping paper on the cigarette pack when the cigarette pack just rolls into the arc-shaped rubbing surface.

[0007] Furthermore, the length of the groove is greater than or equal to the width of the cork paper.

[0008] Furthermore, the arc-shaped rubbing surface includes a rubbing area near the side where the tobacco rolls in and a smoke exit area near the side where the tobacco rolls out. The rubbing area is used to pull the tobacco roll out of the smoke receiving groove of the rubbing drum and to guide the tobacco roll to rotate. The strip groove is provided in the rubbing area, and the smoke exit area is used to make the tobacco roll out.

[0009] Furthermore, the smoke output area includes a stabilizing portion near the smoke-rubbing area and a fast-output portion away from the smoke-rubbing area. The stabilizing portion is used to stabilize the smoke output, and the fast-output portion is used to make the smoke output rapid.

[0010] Furthermore, both the rubbing area and the stabilizing part are rough surfaces with transverse serrated lines, while the fast-ejection part is a smooth surface.

[0011] Furthermore, the arc-shaped rubbing surface also includes a clearance opening away from the end where the smoke assembly rolls in. The clearance opening penetrates the rubbing plate body, and the return drum pulls the smoke assembly out through the clearance opening.

[0012] Furthermore, the clearance openings are multiple ones arranged longitudinally along the body of the washboard, and the multiple clearance openings correspond to multiple teeth arranged longitudinally on the return drum.

[0013] Furthermore, the washboard also includes a connecting plate disposed on the washboard body, the connecting plate having multiple connecting holes for connecting with the washboard driving mechanism.

[0014] Furthermore, the arc-shaped rubbing surface also includes limiting areas on both sides of the rubbing area, and the limiting areas are smooth surfaces.

[0015] Furthermore, a glue discharge groove is provided in the middle of the rubbing area, and the glue discharge groove extends laterally on the arc-shaped rubbing surface, with the length of the extension being equal to the lateral width of the arc-shaped rubbing surface.

[0016] The rubbing plate of the cigarette-rubbing device for a cigarette-feeding machine proposed in this utility model has the following beneficial effects: (1) The arc-shaped rubbing surface of this rubbing board is provided with a strip groove at the end near the tobacco roll in. When the tobacco rolls in from the first end of the arc-shaped rubbing surface, the strip groove avoids the tipping paper on the tobacco roll, so that when the tobacco roll just rolls into the arc-shaped rubbing surface, the tipping paper on the tobacco roll does not contact the arc-shaped rubbing surface, thereby preventing the tipping paper from folding and ensuring the rubbing quality of the filter cigarette, and thus ensuring the production quality of the cigarette. (2) The strip groove of this rubbing board extends laterally on the arc-shaped rubbing surface, and the length of the lateral extension of the strip groove is set to be greater than or equal to the width of the tipping paper. When the tobacco rolls into the arc-shaped rubbing surface, the strip groove avoids the tipping paper on the tobacco roll, so that the tipping paper on the tobacco roll does not come into contact with the arc-shaped rubbing surface, thereby preventing the tipping paper from folding and ensuring the rubbing quality of the filter cigarette, and thus ensuring the production quality of the cigarette. (3) The arc-shaped rubbing surface of this rubbing board includes a rubbing area near the side where the smoke group rolls in and a smoke exit area near the side where the smoke group rolls out. The rubbing area is used to pull the smoke group out of the smoke receiving groove of the rubbing drum and to guide the smoke group to rotate. The smoke exit area is used to make the smoke group roll out, thereby making the rubbing of the smoke group simpler, more convenient and easier to implement. (4) The smoke outlet area of ​​this rubbing board includes a stabilizing part located on the side close to the rubbing area and a fast-out part located on the side away from the rubbing area. The stabilizing part is used to make the smoke group roll out stably, and the fast-out part is used to make the smoke group roll out quickly, thereby further ensuring the rubbing quality of the filter cigarette and thus ensuring the production quality of the cigarette. (5) The rubbing area and the stabilizing part of this rubbing board are rough surfaces with transverse sawtooth straight lines, while the quick-out part is a smooth surface. Through the friction of the rubbing area, the tobacco group is pulled out from the tobacco receiving groove of the rubbing drum and the tobacco group is guided to rotate. Through the friction of the stabilizing part, the tobacco group rolls out stably, and the quick-out part makes the tobacco group roll out quickly, thereby further ensuring the rubbing quality of the filter cigarette and thus ensuring the production quality of the cigarette. (6) The arc-shaped joint surface of this rubbing board also includes an avoidance opening. When the tobacco group rolls to the end of the arc-shaped joint surface, since the avoidance opening penetrates the rubbing board body, the teeth of the return drum can extend between the rubbing board body and the joint drum through the avoidance opening. Thus, by rotating the return drum, the teeth of the return drum can carry the tobacco group between the rubbing board body and the joint drum out and transfer it to the next process, thereby completing the jointing of the tobacco. (7) The arc-shaped rubbing surface of this rubbing board also includes a limiting area. The limiting area is set on both sides of the rubbing area and the limiting area is a smooth surface. During the process of rubbing the tipping paper on the tobacco group in the rubbing area, the limiting area on both sides of the rubbing area limits the area on both sides of the tobacco group that is not covered with tipping paper, so that the rubbing of tipping paper is more stable, further ensuring the rubbing quality of the filter cigarette, and thus ensuring the production quality of the cigarette. (8) A glue discharge groove is provided in the middle of the rubbing area of ​​this rubbing board. The glue discharge groove extends laterally on the arc-shaped rubbing surface, and the length of the extension is equal to the lateral width of the arc-shaped rubbing surface. During the rubbing process of the tobacco group, the excess glue overflowing from the edge of the tobacco group is discharged through the glue discharge groove. This not only prevents the overflowing glue from affecting the wrapping and bonding of the tipping paper to the tobacco group and ensures the quality of the tobacco group rubbing, but also facilitates the cleaning and maintenance of this rubbing board.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1-4 The present invention discloses a rubbing plate of a cigarette-rubbing device for a cigarette-loading machine, comprising a rubbing plate body 11 and an arc-shaped rubbing surface 12 disposed on one side of the rubbing plate body 11. The cigarette pack 4 rolls in from one end of the arc-shaped rubbing surface 12 and rolls out from the opposite end of the arc-shaped rubbing surface 12. The arc-shaped rubbing surface 12 is provided with a strip groove 121 near the end where the cigarette pack 4 rolls in. The strip groove 121 extends laterally on the arc-shaped rubbing surface 12 and corresponds to the position of the tipping paper in the cigarette pack 4, so as to avoid the tipping paper on the cigarette pack 4 when the cigarette pack 4 just rolls into the arc-shaped rubbing surface 12.

[0022] In this application, the rubbing board 1 includes a rubbing board body 11 and an arc-shaped rubbing surface 12, with the arc-shaped rubbing surface 12 disposed on one side of the rubbing board body 11. When rubbing the cigarettes together, the cigarette pack 4 rolls in from one end of the arc-shaped rubbing surface 12 and rolls out from the opposite end of the arc-shaped rubbing surface 12. The end where the cigarette pack 4 rolls in is considered the beginning end of the arc-shaped rubbing surface 12, and the end where the cigarette pack 4 rolls out is considered the end of the arc-shaped rubbing surface 12.

[0023] Since the arc-shaped rubbing surface 12 corresponds to the outer circle of the rubbing drum 2, and the distance between the arc-shaped rubbing surface 12 and the outer circle of the rubbing drum 2 is the diameter of the cigarette minus 0.7mm, when the cigarette pack 4 on the rubbing drum 2 runs to the beginning of the arc-shaped rubbing surface 12, the arc-shaped rubbing surface 12 will carry the cigarette pack 4 out of the cigarette receiving groove of the rubbing drum 2.

[0024] At this time, the joining drum 2 continues to rotate, causing the tobacco assembly 4 to roll between the arc-shaped joining surface 12 and the outer circular surface of the joining drum 2, so that the cork paper on the tobacco assembly 4 tightly wraps and adheres to the tobacco assembly 4; when the tobacco assembly 4 rolls to the end of the arc-shaped joining surface 12, the return drum 3 takes the tobacco assembly 4 out between the arc-shaped joining surface 12 and the joining drum 2 and transfers it to the next process, thus completing the joining of the cigarettes.

[0025] When the twisting drum 2 runs at high speed, it drives the tobacco pack 4 to the first end of the arc-shaped twisting surface 12. When the arc-shaped twisting surface 12 brings the tobacco pack 4 out of the tobacco receiving groove of the twisting drum 2, at the moment when the tipping paper on the tobacco pack 4 comes into contact with the arc-shaped twisting surface 12, the overlap between the tipping paper and the tobacco pack 4 is prone to folding, which affects the twisting quality and thus the quality of cigarette production.

[0026] Therefore, in this application, a strip groove 121 is provided at the end of the arc-shaped twisting surface 12 near where the tobacco pack 4 rolls in, that is, the strip groove 121 is located at the beginning of the arc-shaped twisting surface 12. Since the strip groove 121 extends laterally on the arc-shaped twisting surface 12 and corresponds to the position of the tipping paper on the tobacco pack 4, when the tobacco pack 4 rolls in from the beginning of the arc-shaped twisting surface 12, the strip groove 121 avoids the tipping paper on the tobacco pack 4, so that when the tobacco pack 4 just rolls into the arc-shaped twisting surface 12, the tipping paper on the tobacco pack 4 does not contact the arc-shaped twisting surface 12, thereby preventing the tipping paper from folding, ensuring the twisting quality of the filter cigarette, and thus ensuring the production quality of the cigarette.

[0027] In this embodiment, the length of the strip groove 121 is greater than or equal to the width of the tipping paper. In this application, when the rubbing board 1 and the rubbing drum 2 rub the tobacco group 4, the tobacco group 4 rolls vertically between the rubbing board 1 and the rubbing drum 2, so that the tipping paper on the tobacco group 4 overlaps laterally with the arc-shaped rubbing surface 12 in the width direction.

[0028] In this application, the strip groove 121 extends laterally on the arc-shaped twisting surface 12. Therefore, the length of the laterally extended strip groove 121 is set to be greater than or equal to the width of the tipping paper. When the cigarette pack 4 rolls into the arc-shaped twisting surface 12, the strip groove 121 avoids the tipping paper on the cigarette pack 4, so that the tipping paper on the cigarette pack 4 does not come into contact with the arc-shaped twisting surface 12, thereby preventing the tipping paper from folding and ensuring the twisting quality of the filter cigarette, and thus ensuring the production quality of the cigarette.

[0029] In this embodiment, the arc-shaped rubbing surface 12 includes a rubbing area 122 near the side where the tobacco group 4 rolls in, and a smoke exit area 123 near the side where the tobacco group 4 rolls out. The rubbing area 122 is used to pull the tobacco group 4 out of the smoke receiving groove of the rubbing drum 2 and to guide the tobacco group 4 to rotate. The strip groove 121 is provided in the rubbing area 122, and the smoke exit area 123 is used to make the tobacco group 4 roll out.

[0030] In this application, the arc-shaped rubbing surface 12 includes a smoke-rubbing area 122 and a smoke-exiting area 123. The smoke-rubbing area 122 is located on the side of the rubbing plate body 11 near the smoke group 4 rolling in, and the smoke-exiting area 123 is located on the side of the rubbing plate body 11 near the smoke group 4 rolling out. That is, the smoke-rubbing area 122 is located at the beginning of the arc-shaped rubbing surface 12, and the smoke-exiting area 123 is located at the end of the arc-shaped rubbing surface 12.

[0031] When the tobacco bundle 4 on the twisting drum 2 reaches the beginning of the arc-shaped twisting surface 12, the twisting zone 122 pulls the tobacco bundle 4 out of the tobacco receiving groove of the twisting drum 2. After the tobacco bundle 4 is pulled out of the tobacco receiving groove of the twisting drum 2, it rolls between the twisting zone 122 and the outer circular surface of the twisting drum 2 due to the continuous rotation of the twisting drum 2 and the guidance of the twisting zone 122. This tightly wraps the tipping paper on the tobacco bundle 4 around the outer periphery of the tobacco bundle 4, thus completing the twisting of the tipping paper. When the tobacco bundle 4 rolls to the end of the arc-shaped twisting surface 12, the returning drum 3 carries the tobacco bundle 4 out from between the tobacco exit zone 123 and the twisting drum 2 and transfers it to the next process, thus completing the twisting of the cigarette.

[0032] In this application, the strip groove 121 is set in the tobacco-rubbing area 122 and located at the first end of the tobacco-rubbing area 122. When the tobacco group 4 on the rubbing drum 2 runs to the first end of the arc-shaped rubbing surface 12, the tobacco-rubbing area 122 pulls the tobacco group 4 out of the tobacco-receiving groove of the rubbing drum 2. The strip groove 121 avoids the water tipping paper on the tobacco group 4, so that the water tipping paper on the tobacco group 4 does not contact the arc-shaped rubbing surface 12, thereby preventing the water tipping paper from folding and ensuring the rubbing quality of the filter cigarette, and thus ensuring the production quality of the cigarette.

[0033] In this embodiment, the smoke outlet area 123 includes a stabilizing portion 1231 near the smoke-rubbing area 122 and a fast-exit portion 1232 away from the smoke-rubbing area 122. The stabilizing portion 1231 is used to stabilize the smoke assembly 4 during rolling, and the fast-exit portion 1232 is used to quickly roll out the smoke assembly 4. In this application, the smoke outlet area 123 includes a stabilizing portion 1231 and a fast-exit portion 1232. The stabilizing portion 1231 is disposed near the smoke-rubbing area 122, and the fast-exit portion 1232 is disposed away from the smoke-rubbing area 122, that is, the stabilizing portion 1231 is disposed between the smoke-rubbing area 122 and the fast-exit portion 1232.

[0034] When the cigarette pack 4 rolls from the cigarette rolling area 122 to the cigarette exit area 123, it first passes through the stabilizing part 1231, then through the fast exit part 1232, and then the cigarette pack 4 between the fast exit part 1232 and the rolling drum 2 is brought out by the return drum 3. During this process, the stabilizing part 1231 makes the cigarette pack 4 roll out steadily, and the fast exit part 1232 makes the cigarette pack 4 roll out quickly, thereby further ensuring the rolling quality of the filter cigarette and thus ensuring the production quality of the cigarette.

[0035] Specifically, in this embodiment, both the rubbing area 122 and the stabilizing part 1231 are rough surfaces with transverse serrated lines, while the quick-release part 1232 is a smooth surface. In this application, both the rubbing area 122 and the stabilizing part 1231 are provided with transverse serrated lines, making both the rubbing area 122 and the stabilizing part 1231 rough surfaces, while the quick-release part 1232 is a smooth surface.

[0036] Since the tobacco-rubbing area 122 is a rough surface with transverse serrated straight lines, when the tobacco group 4 on the rubbing drum 2 runs to the beginning of the arc-shaped rubbing surface 12, the friction of the tobacco-rubbing area 122 pulls the tobacco group 4 out of the tobacco-receiving groove of the rubbing drum 2. As the tobacco group 4 rolls between the tobacco-rubbing area 122 and the outer circular surface of the rubbing drum 2, the friction of the tobacco-rubbing area 122 causes the tipping paper on the tobacco group 4 to be tightly wrapped around the outer periphery of the tobacco group 4, thereby completing the rubbing of the tipping paper.

[0037] When the tobacco assembly 4 rolls to the smoke outlet area 123, it first passes through the stabilizing part 1231 and then through the fast-exit part 1232. Since the stabilizing part 1231 is a rough surface with transverse sawtooth grooves and the fast-exit part 1232 is a smooth surface, during the process of the tobacco assembly 4 being carried out between the smoke outlet area 123 and the twisting drum 2 by the returning drum 3, the stabilizing part 1231 makes the tobacco assembly 4 roll out steadily, and the fast-exit part 1232 makes the tobacco assembly 4 roll out quickly, thereby further ensuring the twisting quality of the filter cigarette and thus ensuring the production quality of the cigarette.

[0038] In this embodiment, the arc-shaped rubbing surface 12 further includes a clearance opening 124 at the end away from where the smoke assembly 4 rolls in. The clearance opening 124 penetrates the rubbing plate body 11, and the return drum 3 carries the smoke assembly 4 out through the clearance opening 124. In this application, the arc-shaped rubbing surface 12 also includes a clearance opening 124, which is located at the end of the rubbing plate body 11 away from where the smoke assembly 4 rolls in, that is, the clearance opening 124 is located at the tail end of the arc-shaped rubbing surface 12.

[0039] When the tobacco assembly 4 rolls to the end of the apex of the rubbing surface, since the clearance opening 124 penetrates the rubbing plate body 11, the teeth of the return drum 3 can extend between the rubbing plate body 11 and the rubbing drum 2 through the clearance opening 124. Thus, by rotating the return drum 3, the teeth of the return drum 3 will carry the tobacco assembly 4 between the rubbing plate body 11 and the rubbing drum 2 out and transfer it to the next process, thereby completing the rubbing of the tobacco.

[0040] Furthermore, in this embodiment, the clearance openings 124 are multiple ones arranged longitudinally along the rubbing plate body 11. The multiple clearance openings 124 correspond to the multiple teeth arranged longitudinally along the return drum 3. Therefore, the multiple teeth arranged longitudinally along the return drum 3 can extend between the rubbing plate body 11 and the rubbing drum 2 after passing through the multiple clearance openings 124 arranged longitudinally along the rubbing plate body 11. Thus, by rotating the return drum 3, the multiple teeth arranged longitudinally along the return drum 3 can simultaneously carry out the rubbed tobacco group 4 between the rubbing plate body 11 and the rubbing drum 2, and transfer it to the next process, thereby completing the rubbing of the tobacco.

[0041] In this embodiment, the washboard 1 further includes a connecting plate 13 disposed on the washboard body 11. The connecting plate 13 has multiple connecting holes for connecting with the washboard driving mechanism. In actual implementation, the washboard 1 is connected to the washboard driving mechanism, which is typically a telescopic cylinder mechanism.

[0042] During the splicing of tobacco pack 4, the rubbing plate drive mechanism extends and sends the rubbing plate 1 between the splicing drum 2 and the return drum 3, so that the rubbing plate 1 can work with the splicing drum 2 to tightly wrap the tipping paper on the tobacco pack 4 around the outer periphery of the tobacco pack 4; after the splicing is completed, the rubbing plate drive mechanism retracts and drives the rubbing plate 1 to move away from the splicing drum 2 and the return drum 3, so as to facilitate the cleaning and maintenance of the splicing drum 2 and the return drum 3.

[0043] Therefore, in this application, the washboard 1 also includes a connecting plate 13, which is disposed on the washboard body 11. The connecting plate 13 is connected to the washboard driving mechanism through the connecting hole 131 provided thereon, thereby connecting the washboard 1 to the washboard driving mechanism and enabling the washboard driving mechanism to drive the washboard 1 to move.

[0044] When the tobacco group 4 is being rubbed together, the rubbing plate drive mechanism sends the rubbing plate body 11 between the rubbing drum 2 and the return drum 3 through the connecting plate 13; after the rubbing is completed, the rubbing plate drive mechanism drives the rubbing plate body 11 to move away from the rubbing drum 2 and the return drum 3 through the connecting plate 13.

[0045] In this embodiment, the arc-shaped twisting surface 12 further includes limiting areas 125 disposed on both sides of the tobacco twisting area 122, and the limiting areas 125 are smooth surfaces. In this application, the arc-shaped twisting surface 12 also includes limiting areas 125, which are disposed on both sides of the tobacco twisting area 122, and the limiting areas 125 are smooth surfaces. During the twisting process of the tobacco twisting area 122 on the tipping paper of the tobacco pack 4, the limiting areas 125 on both sides of the tobacco twisting area 122 limit the areas on both sides of the tobacco pack 4 that are not covered with tipping paper, thereby making the twisting of the tipping paper more stable, further ensuring the twisting quality of the filter cigarette, and thus ensuring the production quality of the cigarette.

[0046] In this application, the rubbing area 122 is a rough surface with transverse serrated lines, while the limiting areas 125 on both sides of the rubbing area 122 are smooth surfaces. Therefore, it is foreseeable that: on the transverse length of the arc-shaped rubbing surface 12, the transverse serrated lines cover part of the length of the arc-shaped rubbing surface 12 to form the rubbing area 122, while the lengths not covered by the transverse serrated lines on both sides form the limiting areas 125.

[0047] In this embodiment, a glue discharge groove 126 is provided in the middle of the tobacco-rubbing area 122. The glue discharge groove 126 extends laterally on the arc-shaped rubbing surface 12, and the length of the extension is equal to the lateral width of the arc-shaped rubbing surface 12. In order to ensure that the tobacco assembly 4 can be tightly wrapped and bonded by the tipping paper on the tobacco assembly 4 when it rolls between the arc-shaped rubbing surface 12 and the outer circular surface of the rubbing drum 2, glue is usually coated on the tipping paper.

[0048] As the cigarette pack 4 rolls between the arc-shaped rubbing surface 12 and the outer circular surface of the rubbing drum 2, the excess glue on the tipping paper will overflow from the edge of the cigarette pack 4 under the action of the arc-shaped rubbing surface 12 and the rubbing drum 2.

[0049] Therefore, in this application, a glue discharge groove 126 is provided in the middle of the rubbing area 122 of the arc-shaped rubbing surface 12, and the glue discharge groove 126 extends laterally on the arc-shaped rubbing surface 12, so that when the smoke group 4 rolls between the rubbing area 122 and the outer circular surface of the rubbing drum 2, the glue overflowing from the edge of the smoke group 4 is collected in the glue discharge groove 126 in the middle of the rubbing area 122.

[0050] Since the length of the glue discharge groove 126 extending laterally on the arc-shaped joint surface 12 is equal to the lateral width of the arc-shaped joint surface 12, that is, the two ends of the glue discharge groove 126 are connected to the outside, the excess glue collected in the glue discharge groove 126 can be discharged. This can prevent the overflowing glue from affecting the wrapping and bonding of the tipping paper to the tobacco group 4, ensuring the quality of the joint of the tobacco group 4, and also facilitate the cleaning and maintenance of this washboard 1.
