Description

Technical Field

[0001] The invention belongs to the technical field of tobacco detection devices, and in particular relates to a tobacco leaf redrying full-automatic sampling and sample sending device. Background Art

[0002] In tobacco production, it is necessary to sample tobacco leaves packed in cartons and use the tobacco samples to detect density deviation of the tobacco leaves in the corresponding cartons. However, traditional tobacco sampling is done manually, which not only wastes manpower, but also has low efficiency. In addition, the samples taken manually in the cartons are not uniform, which affects the test results.

[0003] The Chinese patent with the authorization announcement number CN217006402U discloses a multi-point sampling device, including a conveying mechanism for conveying cartons, and a sampling device arranged above the conveying mechanism for taking out materials in the cartons, the sampling device including a frame, a pressure head, a plurality of sampling tubes arranged below the pressure head, and a first lifting mechanism arranged on the frame for driving the pressure head downward or upward. The above scheme drives the pressure head and the sampling tube arranged below the pressure head downward into the carton through the first lifting mechanism, so that the tobacco leaves in the carton enter the sampling tube, thereby realizing the automatic sampling of tobacco leaves.

[0004] However, after the above scheme obtains the tobacco leaf sample through the sampling tube, the sample needs to be taken out of the sampling tube and then transferred to the laboratory for crushing and testing. The entire post-sampling post-processing process is complicated and cumbersome, and is usually handled manually, resulting in low detection efficiency after sampling.

[0005] A Chinese patent with authorization announcement number CN204400174U discloses a tobacco sampling box pneumatic pipeline conveying device, which includes a conveying pipeline composed of a closed pipeline, on which a first delivery receiving port and a second delivery receiving port are provided, and also includes a high-pressure fan so that the sampling box can achieve two-way rapid transmission under the action of the high-pressure fan and various control valves, thereby achieving the purpose of switching the reciprocating conveying direction of the loaded and empty sampling boxes.

[0006] However, after sampling, the above scheme still requires manual removal of the sample from the sampling tube and placing it into a sampling bottle and sealing it, and then manually placing the sampling bottle into the wind duct for transportation. The whole process requires a lot of manpower, increases labor intensity, and limits detection efficiency.

[0007] At the same time, the samples taken out by the existing sampling tube are usually all put into the sampling bottle at one time, and only the density of the tobacco leaves in the carton is tested. There is a lack of segmented collection of the samples taken out of the sampling tube, which is not suitable for layered moisture detection of the tobacco leaves in the carton.

[0008] At the same time, the samples taken out by the sampling tube are relatively dense, and need to be crushed in the laboratory for convenient testing. The bottling process after sampling lacks a crushing step, and direct testing of the samples after sampling cannot be achieved.

[0009] Therefore, there is an urgent need for a tobacco leaf redrying fully automatic sampling and sample delivery device to automate the entire process of sample taking, layering, bottling and sample delivery. Summary of the invention

DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 11 , the present invention provides a technical solution: like Figure 1-Figure 11 As shown, a tobacco leaf redrying fully automatic sampling and sample delivery device is located on one side of a baler 1, and includes a sampling component 2, a crushing component 3, a collecting component 4, a sealing component 5 and an air delivery component 6. The sampling component 2 is connected to the door beam of the baler 1. The sampling component 2 includes a screw lifting component 24, a sampling tube 21 and a sample pushing cylinder 23. The sampling tube 21 is pressed down by the screw lifting component 24 for sampling, and the tobacco leaves in the sampling tube 21 are pushed out by the sample pushing cylinder 23. The crushing assembly 3 is fixed at the bottom of the screw lifting assembly 24. The crushing assembly 3 includes a telescopic assembly and a cutter head 36. The cutter head 36 reciprocates through the telescopic assembly. The cutter head 36 is used to cut the tobacco leaves pushed out of the sampling tube 21. The collecting assembly 4 includes a column 41, a rotation drive mechanism and a limit plate 47. A plurality of limit plates 47 are connected to the rotation drive mechanism. A hinge plate 48 is provided below each limit plate 47. Both the hinge plate 48 and the limit plate 47 are rotated by the rotation drive mechanism. A limit cylinder 49 for placing the sampling bottle 7 is provided on the limit plate 47. The collecting assembly 4 is used to collect tobacco leaves pushed out of the sampling tube 21. The sealing assembly 5 is located on the collecting assembly 4, and the sealing assembly 5 includes a placing tube 52 and a pressing cylinder 51. A plurality of bottle caps 71 are arranged in the placing tube 52, and the pressing cylinder 51 is used to seal the bottle caps 71 with the sampling bottle 7; The air delivery component 6 is located at one side of the collecting component 4 , and the air delivery component 6 is used to deliver the sealed sampling bottle 7 .

[0028] Specifically, after the tobacco is packed, it is sent to the bottom of the baler 1 through the conveyor belt. At this time, the lower pressure plate of the baler 1 is in a retracted state. The state of the lower pressure plate of the baler 1 can be referred to as Figure 1 At this time, the sampling component 2 is also in a contracted state. The contracted state of the sampling component 2 can also be referred to in Figure 1 Under the action of the lead screw lifting assembly 24, the sampling tube 21, the connecting plate 22 and the sample pushing cylinder 23 are all lifted.

[0029] like Figure 2 As shown, the baler 1 presses down the lower pressure plate through the hydraulic cylinder. At this time, the lower pressure plate extends into the cigarette box to compact the tobacco. An opening is provided on the lower pressure plate for the sampling tube 21 to extend into. At the same time, the outer frame of the screw lifting assembly 24 is fixed to the door beam of the baler 1. A connecting plate 22 is provided on the slider of the screw lifting assembly 24. At this time, under the action of the screw lifting assembly 24, the sampling tube 21, the connecting plate 22 and the sample pushing cylinder 23 move downward as a whole, and the sampling tube 21 is inserted into the tobacco for sampling.

[0030] like Figure 1 As shown, after sampling is completed, the sampling tube 21 is raised by the screw lifting assembly 24, and the baler 1 is also lifted after the pressing is completed, so as to facilitate the transfer of the cigarette box after compaction, and the lower pressing plate of the baler 1 does not interfere with the structure of this solution. The lower end of the sampling tube 21 is extended to a position just above the cutter head 36 by the screw lifting assembly 24.

[0031] like Figure 5-Figure 6As shown, a mounting plate 42 is provided on the top of the column 41, and the rotary drive mechanism includes a brake motor 43 located above the mounting plate 42 and a bearing 44, a sleeve 45 and a gear ring 46 located below the mounting plate 42, the inner ring of the bearing 44 is interference fit with the column 41, the inner ring of the sleeve 45 is interference fit with the outer ring of the bearing 44, the inner ring of the gear ring 46 is interference fit with the outer ring of the sleeve 45, and the motor shaft of the brake motor 43 passes through the mounting plate 42 and meshes with the gear ring 46 through gears.

[0032] Therefore, the brake motor 43 drives the ring gear 46 to rotate through the gear, and the ring gear 46 drives the sleeve 45 to rotate around the column 41, and then the limit plate 47 and the hinge plate 48 outside the sleeve 45 rotate synchronously. The column 41 is located below the sleeve 45 and is provided with a support plate 411. A ball is provided between the support plate 411 and the sleeve 45. The support plate 411 is used to limit and support the sleeve 45. At the same time, the ball also facilitates the rotation of the sleeve 45 and reduces friction.

[0033] At the same time, the limiting tube 49 on the limiting plate 47 is convenient for placing the sampling bottle 7. Since the limiting tube 49 has a hole at the bottom, the limiting plate 47 and the hinged plate 48 have the same size. When the sampling bottle 7 is located in the limiting tube 49, the bottom of the sampling bottle 7 will fall directly onto the hinged plate 48 below.

[0034] Furthermore, if Figure 5-Figure 6 As shown, in this embodiment, three sets of limit plates 47 are arranged outside the sleeve 45, and the angle between two adjacent sets of limit plates 47 is 90°. Figure 6 As shown, the limit plate 47 is located in the upper, left and lower directions of the sleeve 45 in the top view, wherein the limit plate on the left side is blocked by the sealing component. Figure 6 Indicated by dotted lines. The absence of a limit plate 47 on the right side of the sleeve 45 from a top-down perspective can avoid interference and collision with the sampling assembly 2. Three sampling bottles 7 without bottle caps 71 are placed in the corresponding three limit cylinders 49 in advance. At this time, the uppermost limit cylinder 49 of the sleeve 45 from a top-down perspective is just at a 90° angle with the sampling tube 21 on the right. At this time, the brake motor 43 is started to drive the limit plate 47 to rotate. The brake motor 43 adopts a stepping motor form, which can accurately control the rotation angle. Therefore, the limit plate 47 is rotated 90° clockwise by the brake motor 43, and the upper set of limit plates 47, limit cylinder 49 and sampling bottle 7 are just rotated to the bottom of the sampling tube 21. At the same time, the highest point of the sampling bottle 7 is lower than the highest point of the limit cylinder 49, and the tobacco sample pushed out by the sampling tube 21 can be easily stored in the sampling bottle 7 below.

[0035] Furthermore, the highest point of the limiting cylinder 49 is lower than the lowest point of the crushing assembly 3 , and the lowest point of the hinged plate 48 is higher than the cigarette box in the baler 1 , so the hinged plate 48 will not interfere with the cigarette box when it rotates, and the limiting cylinder 49 will not collide with the crushing assembly 3 .

[0036] like Figure 3 As shown, the sampled tobacco is in a compact state and filled in the sampling tube 21. Since one end of the sampling tube 21 is fixed below the connecting plate 22, and the sample-pushing cylinder 23 is fixed above the connecting plate 22, the piston rod of the sample-pushing cylinder 23 passes through the connecting plate 22 and extends into the sampling tube 21, and the piston rod end of the sample-pushing cylinder 23 is matched with the inner wall of the sampling tube 21. At this time, the tobacco in the sampling tube 21 is pushed out from the other end by the sample-pushing cylinder 23.

[0037] like Figure 4 As shown, the telescopic assembly includes a driving motor 31, a cam 32 and a T-shaped push rod 33. The driving motor 31 is located on one side of the bottom of the screw lifting assembly 24 and is fixed to the outer frame of the screw lifting assembly 24. The cam 32 is fixed on the motor shaft of the driving motor 31. The T-shaped push rod 33 is located on one side of the cam 32. A side plate 34 is provided at the bottom of the outer frame of the screw lifting assembly 24. One end of the T-shaped push rod 33 passes through the side plate 34. A return spring 35 is provided between the end of the T-shaped push rod 33 close to the cam 32 and the side plate 34. The other end of the T-shaped push rod 33 is fixed to the cutter head 36.

[0038] Therefore, the driving motor 31 drives the cam 32 to rotate, the contour of the cam 32 contacts the end of the T-shaped push rod 33, and the T-shaped push rod 33 is reset by the reset spring 35. Under the rotation of the cam 32 and the action of the reset spring 35, the T-shaped push rod 33 performs reciprocating linear motion, thereby driving the cutter head 36 to extend and retract.

[0039] Under the slow push of the sample-pushing cylinder 23, the cutter head 36 continuously cuts and crushes the pushed-out tobacco sample, and the crushed smaller tobacco will enter the sampling bottle 7 below. At this time, the first sample to fall out of the sampling tube 21 is the tobacco at the bottom of the cigarette box. By controlling the pushing distance of the sample-pushing cylinder 23, the sample is pushed out in three sections, corresponding to the upper, middle and lower layers of tobacco in the cigarette box. After the first section of tobacco is pushed out and cut, the sample-pushing cylinder 23 is paused, and the brake motor 43 continues to rotate clockwise by 90°. At this time, the sampling bottle 7 for collecting the lower layer sample is rotated out, and another empty sampling bottle 7 enters the bottom of the sampling tube 21. At this time, the sample-pushing cylinder 23 is restarted, and the crushing component 3 is started at the same time to crush and collect the middle layer of tobacco; this reciprocating process is repeated to crush and collect the upper layer sample.

[0040] At this time, the three sampling bottles 7 respectively collect tobacco samples from the upper, middle and lower layers in the cigarette box, which can effectively detect the moisture content of the three layers of tobacco in the cigarette box, and each tobacco sample in the sampling bottle 7 is cut and crushed by the crushing component 3, which is convenient for subsequent direct testing. At the same time, the crushed tobacco can also be better collected by the sampling bottle 7.

[0041] Figure 8As shown, the bottle cap 71 is a T-shaped structure, the outer diameter of the large end of the bottle cap 71 is the same as the outer diameter of the sampling bottle 7, and the outer diameter of the small end of the bottle cap 71 is adapted to the inner diameter of the bottle mouth of the sampling bottle 7. The small end of the bottle cap 71 is made of rubber material, which facilitates the small end of the bottle cap 71 to be inserted into the bottle mouth and maintain a seal, and then abut against the bottle mouth through the large end of the bottle cap 71.

[0042] like Figure 7 As shown, a plurality of bottle caps 71 are sequentially placed in the placement tube 52 from top to bottom. The placement tube 52 is fixed to the mounting plate 42. Both upper and lower ends of the placement tube 52 are open. The bottom of the placement tube 52 passes through the mounting plate 42. A plurality of hinged rods 53 are provided at the bottom opening of the placement tube 52. The middle portion of the hinged rod 53 is hinged to the placement tube 52. One end of the hinged rod 53 extends into the placement tube 52 and abuts against the large end of the bottle cap 71. The other end of the hinged rod 53 is connected to the tube wall of the placement tube 52 through a compression spring 54.

[0043] Through the above technical solution, multiple bottle caps 71 are stacked up and down in the placement tube 52, and the bottom placement tube 52 is supported by the hinge rod 53 and pulled by the compression spring, so that the multiple bottle caps 71 will not fall out of the placement tube 52.

[0044] Since the lowest point of the bottle cap 71 at the bottom of the placement tube 52 is higher than the highest point of the limiting tube 49, the center of the placement tube 52 is located on the central rotation path of the limiting tube 49. The placement tube 52 of this embodiment is located at the leftmost side of the mounting plate 42. When the sampling bottle 7 rotates clockwise to the bottom of the placement tube 52 after sampling, the downward pressure cylinder 51 is started. The downward pressure cylinder 51 is fixed on the mounting plate 42. The piston rod of the downward pressure cylinder 51 extends from the top of the placement tube 52 into the placement tube 52. The piston rod of the downward pressure cylinder 51 drives the stacked bottle caps 71 to move downward. At this time, the bottle cap 71 at the bottom drives the hinge rod 53 to rotate outward under the pressure. The hinge rod 53 opens, and the bottle cap 71 at the bottom can fall into the sampling bottle 7 below. At the same time, the pressing cylinder 51 continues to press downward, and the lower end of the second-to-last bottle cap 71 abuts against the lowest bottle cap 71 and is pressed into the sampling bottle 7, completing the sealing of the bottle cap 71 and the sampling bottle 7. At this time, the pressing distance of the pressing cylinder 51 will not cause the second-to-last bottle cap 71 to completely fall out of the placing tube 52. At this time, the pressing cylinder 51 is stopped. At this time, the bottle cap 71 at the bottom of the placing tube 52 continues to be abutted and will not fall out under the reset of the hinged rod 53.

[0045] Furthermore, the air delivery assembly 6 includes an air duct 61, a bellows 62 and an inlet 63 located at the top of the bellows 62, the bellows 62 is connected to the air duct 61, the inner dimensions of the air duct 61 are adapted to the outer dimensions of the sampling bottle 7, the bellows 62 is located on one side of the sealing assembly 5, the highest point of the inlet 63 is lower than the lowest point of the hinged plate 48, and the center of the inlet 63 is located on the rotation path of the center of the limiting cylinder 49.

[0046] A telescopic cylinder 64 is provided on one side of the bellows 62 located at the inlet 63. When the piston rod of the telescopic cylinder 64 is fully extended, it just abuts against the hinged plate 48 and is lower than the limit plate 47. When the piston rod of the telescopic cylinder 64 is retracted, it is lower than the lowest point of the hinged plate 48 and the limit plate 47 is fixed outside the sleeve 45.

[0047] Specific as Figure 9-11 As shown, after the sampling bottle 7 is connected to the bottle cap 71 through the sealing assembly 5, the telescopic cylinder 64 extends out. At this time, the sealed sampling bottle 7 corresponds to the hinged plate 48 below, and abuts against the piston rod of the telescopic cylinder 64. Since the hinged plate 48 is hinged to the sleeve 45, a tension spring 410 is provided between the hinged plate 48 and the sleeve 45. After the hinged plate 48 is abutted by the piston rod, the hinged plate 48 will not rotate synchronously with the upper limit plate 47. At this time, the limit plate 47, the limit cylinder 49 and the sampling bottle 7 will gradually form a clamp with the hinged plate 48 below. As the clamping becomes larger, the opening below the limit cylinder 49 leaks out, and at the same time it just corresponds to the front inlet 63. At this time, the sampling bottle 7 will directly fall from the opening of the limit cylinder 49 into the inlet 63 without the abutment of the hinged plate 48 below, and then the sampling bottle 7 will be sent to the laboratory through the air delivery assembly 6.

[0048] After the sampling bottle 7 falls into the air delivery assembly 6, the telescopic cylinder 64 is retracted, and the hinged plate 48 is reset under the action of the tension spring 410. Under the action of the limit plate 47, the hinged plate 48 and the telescopic cylinder 64, the sampling bottle 7 can be easily collected into the inlet 63, reducing manpower and improving efficiency.

[0049] Furthermore, the openings of the limiting tube 49 and the inlet 63 are both provided with bell mouths. The bell mouth of the limiting tube 49 facilitates the collection of the cut tobacco into the sampling bottle 7 to avoid tobacco splashing; and the bell mouth of the inlet 63 facilitates the sampling bottle 7 to fall smoothly into the bellows 62.

[0050] Furthermore, a QR code is provided on the bottle cap 71 to record the sample information in the system background to avoid confusion of multiple layers of samples after being air-transported. When the sample bottle and the bottle cap 71 return to their original positions, the original QR code information has been cleared and the information is re-scanned.

[0051] Furthermore, the air delivery component 6 adopts a circulation structure, which delivers samples while returning the empty sampling bottles 7. At the same time, a reverse fan is set at the end to slow down the falling of the sampling bottles 7 and protect the sampling bottles 7.

[0052] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, and should be within the scope of protection of the claims attached to the present invention.
