Description

Technical Field

[0001] The invention belongs to the field of wire cutters, and in particular relates to a wire cutter and a method for automatically detecting and adjusting material density. Background Art

[0002] The tobacco shredder used in the tobacco industry is one of the main equipment on the silk production line. It is responsible for cutting tobacco materials into shreds evenly to meet the requirements of subsequent silk production and cigarette making processes. The shredding process can be briefly described as follows: the tobacco materials with a set flow rate are conveyed and compacted by upper and lower conveyor belts with a certain angle, gradually forming a compact "tobacco cake" and output to the knife entrance, and are continuously cut into tobacco or stem shreds of the required width by the high-speed rotating blade. The density of the tobacco cake affects the shredding process and thus affects the quality of the cut tobacco. If the density of the tobacco cake is too high, the cutting resistance of the shredded tobacco is too large, and the looseness of the cut tobacco is not good, which affects the subsequent processing; if the density of the tobacco cake is too low, the blade will pull out the material during the shredding process, and the cut material cannot be in shredded form, which will affect the subsequent processing; and if the density of the tobacco cake is uneven, unqualified tobacco shreds in the above two situations will appear, which will also affect the subsequent processing. Therefore, it is crucial to ensure that the density of the tobacco cake at the knife entrance is uniform and meets the standard for whether qualified tobacco shreds can be cut.

[0003] In the tobacco industry, there is a non-destructive test for the density deviation rate of tobacco leaves in the box. GB / T31786 adopts the ionizing radiation method, that is, the use of X-ray detectors for testing. As of now, there is no application invention for testing the density of tobacco cakes in the shredded process.

[0004] The shredding equipment currently in use on the market all has control over the incoming material flow. Generally, a combination of a feeder, a limiting tube, and a belt scale is used to achieve a stable flow of incoming materials to the shredder. The above measures provide a basis for improving the uniformity of the density of the tobacco cake at the knife entrance of the shredder. The cross-flow material is continuously pushed in by the push plate through the feeding equipment, or conveyed to the compaction silo of the shredder through the feeding vibration trough. Uniform flow control is beneficial to the forward direction of the material, but it cannot effectively control the width direction of the material. Uneven feeding in the width direction will eventually lead to uneven tobacco cakes in the width direction, affecting shredding.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a wire cutter, which detects the density information of the material in the width direction of material transportation in real time through a detection device, compares the density information with the preset information, and when the material density needs to be adjusted, the controller controls the adjustment device to adjust the material density, thereby improving the uniformity of the material density in the width direction of material transportation, ensuring the smooth completion of the wire cutting action of the wire cutter, reducing the material leakage phenomenon, and improving the wire cutting quality of the material.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a slicing machine, comprising:

[0008] The detection device is used to detect the density information in the width direction of material transportation in real time.

[0009] Adjustment device, used to automatically adjust the material density in the material conveying width direction.

[0010] The controller is used to receive the density information obtained by the detection device, compare it with the preset information, and determine whether to control the adjustment device to adjust the material density according to the comparison result.

[0011] The adjusting device can adjust the material density multiple times until the material density in the material conveying width direction reaches the required uniformity.

[0012] Furthermore, the adjustment device is arranged at the feeding end in the material conveying direction, and comprises:

[0013] A silo has an inlet and an outlet arranged therethrough for feeding materials.

[0014] The adjustment components are arranged in the silo, and n+1 groups are arranged along the material width direction. Material guide channels are formed between adjacent adjustment components. There are n material guide channels, and the size of the material guide channels is adjustable.

[0015] Preferably, along the width direction of the material, the two groups of adjustment components located at the edges are respectively arranged close to the inner wall of the silo.

[0016] The two groups of adjustment components on the edge are respectively arranged close to the inner wall of the silo, so that there is a gap between the two groups of adjustment components on the edge and the inner wall of the silo, but no material guiding channel is formed, which is convenient for the adjustment components to adjust the material density in the material width direction.

[0017] Furthermore, the adjustment component includes:

[0018] The sliding seat is used to adjust the size of the material guide channel.

[0019] The displacement element is connected to the controller at one end and to the sliding seat at the other end, and is used to receive information for adjusting the material density and drive the sliding seat to move.

[0020] The swing plate is connected to the sliding seat and is extended along the material guiding direction.

[0021] The displacement element is preferably a driving cylinder, and the telescopic rod of the driving cylinder is connected to the sliding seat. The sliding seat is driven to move left and right by the telescopic rod, thereby adjusting the size of the material guiding channel; the displacement element can also be other elements that can generate displacement.

[0022] Preferably, a connecting shaft is provided on the sliding seat, and the connecting shaft is movably connected to the swing plate to realize the swing of the swing plate.

[0023] The swinging action of the swing plate on the material is beneficial to the efficiency of material feeding and further improves the uniformity of material density in the width direction of the material.

[0024] Furthermore, the adjustment device also includes:

[0025] The connecting rod is extended along the width direction of the material and connected with each swing plate.

[0026] The driving element is connected to the connecting rod and is used to drive the connecting rod to perform reciprocating periodic motion along the width direction of the material, thereby driving the swing plate to perform reciprocating periodic swing along the width direction of the material.

[0027] Furthermore, the detection device is arranged at the discharge end of the material conveying direction, and comprises:

[0028] The transmitting elements are arranged in n numbers and distributed along the width direction of the material, and are used for transmitting detection lines to the material.

[0029] The receiving elements are arranged in n numbers and distributed along the width direction of the material, and are used for receiving the detection line passing through the material.

[0030] The data processing element is connected to the receiving element, and is used for collecting data and processing it into density information, and transmitting the density information to the controller.

[0031] The transmitting element, the receiving element and the material guiding channel are respectively arranged in one-to-one correspondence.

[0032] Among them, n≥2, preferably, 5≥n≥2.

[0033] A method for automatically detecting and adjusting material density of a shredder is applied to the shredder as described above. The adjustment device of the shredder comprises:

[0034] Silo, for feeding materials.

[0035] The adjustment components are arranged in the silo, and n+1 groups are arranged along the width direction of the material. Material guide channels are formed between adjacent adjustment components, and there are n material guide channels.

[0036] The adjustment component comprises a sliding seat for adjusting the size of the material guiding channel.

[0037] The method comprises the following steps:

[0038] S1: Obtain the density value Pi in the width direction of the material conveying, and calculate the density deviation value δi according to the density value Pi;

[0039] S2: Compare the density deviation value δi with the deviation standard value δk, and when the absolute value of the density deviation value δi is greater than the deviation standard value δk, adjust the material density in the material conveying width direction.

[0040] Furthermore, in step S1, when the material is transported to the discharge end, the density value Pi = {P1, ..., Pn} of the material is obtained, Pi is the density value corresponding to the i-th material guide channel, and the density deviation value δi = {δ1, ..., δn} is calculated according to the density value Pi, δi is the density deviation value corresponding to the i-th material guide channel, wherein,

[0041]

[0042] The step S2 also includes determining that when the absolute value of the density deviation value δi is less than or equal to the deviation standard value δk, there is no need to adjust the material density.

[0043] Further, when the absolute value of δi in step S2 is greater than the deviation standard value δk, step S2 includes:

[0044] When δi is a positive value, the size of the i-th material guide channel is controlled to be reduced;

[0045] Alternatively, when it is determined that δi is a negative value, the size of the i-th material guiding channel is controlled to be increased.

[0046] Further, step S2 includes:

[0047] When i=1, when δ1 is judged to be a positive value, the displacement of the first sliding seat is L1=K1*δ1;

[0048] Alternatively, when δ1 is judged to be a negative value, the displacement of the first sliding seat is L1′=K1*δ1.

[0049] The values ​​of L1 and L1' are the same in magnitude but opposite in direction, that is, when the density deviation value of the material guiding channel is positive or negative, the adjustment amount of the corresponding sliding seat is the same, but the displacement direction is opposite.

[0050] When i=n, ​​when δn is judged to be a positive value, the displacement of the n+1th sliding seat is L(n+1)=K(n+1D*δn;

[0051] Or, when δn is judged to be a negative value, the displacement of the n+1th sliding seat is L(n+l) i =K(n+1)*δn.

[0052] Among them, K1=-K(n+1), that is, when adjusting the sizes of the first material guiding channel and the nth material guiding channel, if they are both increased or decreased, the movement directions of the first sliding seat and the n+1th sliding seat are opposite.

[0053] Further, step S2 includes:

[0054] When i=m, 2≤m≤n-1, when δm is judged to be a positive value, the displacement of the m-th sliding seat is Lm=Km*δm, and the displacement of the m+1-th sliding seat is L(m+1)=K(m+1)*δm;

[0055] Alternatively, when δm is determined to be a negative value, the displacement of the m-th sliding seat is Lm′=Km*δm, and the displacement of the m+1-th sliding seat is L(m+1)′=K(m+1)*δm.

[0056] Among them, Km=-K(m+1), that is, when the mth material guiding channel is adjusted, the mth sliding seat and the m+1th sliding seat move simultaneously, and the moving directions are opposite.

[0057] Km<K1, preferably, Km=(0.4~0.6)K1.

[0058] Since the size of the middle material guiding channel will affect the size of the adjacent material guiding channels and / or edge material guiding channels when the size is adjusted, Km is set to be less than K1 to minimize the impact within the error range without changing the original adjustment amount of the adjacent material guiding channels and / or edge material guiding channels.

[0059] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0060] The present invention provides a wire cutter, which detects density information in the material conveying width direction in real time through a detection device, compares the density information with preset information, and when the material density needs to be adjusted, a controller controls the adjustment device to adjust the material density, thereby improving the uniformity of the material density in the material conveying width direction, ensuring the smooth completion of the wire cutting action of the wire cutter, reducing the material leakage phenomenon, and improving the material wire cutting quality.

[0061] The swinging action of the swing plate on the material is beneficial to the efficiency of material feeding and further improves the uniformity of material density in the width direction of the material.

[0062] The present invention also provides a method for automatically detecting and adjusting the material density of a shredder, which ensures the uniformity of the material density in the width direction of the material conveying by respectively limiting the adjustment methods of the sizes of the first material guide channel, the nth material guide channel and the middle material guide channel.

[0063] Since the size of the middle material guiding channel will affect the size of the adjacent material guiding channels and / or edge material guiding channels when the size is adjusted, Km is set to be less than K1 to minimize the impact within the error range without changing the original adjustment amount of the adjacent material guiding channels and / or edge material guiding channels.

[0076] As an embodiment, the present invention provides a slicing machine, such as Figure 1 As shown, it includes an upper conveyor belt 1 and a lower conveyor belt 2 at a certain angle, which are used to convey materials.

[0077] An upper knife gate seat 3 is arranged at the discharge end of the upper conveyor belt 1, and a lower knife gate seat 4 is arranged at the discharge end of the lower conveyor belt 2, which are used for compacting and cutting materials.

[0082] The detection device is arranged at the discharge end of the material conveying direction, and comprises:

[0083] The transmitting elements are arranged in n numbers and distributed along the width direction of the material, and are used for transmitting detection lines to the material.

[0084] The receiving elements are arranged in n numbers and distributed along the width direction of the material, and are arranged one by one corresponding to the upper and lower positions of the transmitting elements, so as to receive the detection line passing through the material.

[0085] The data processing element 11 is connected to the receiving element, and is used to collect data and process it into density information, and transmit the density information to the controller.

[0086] like Figure 1 and Figure 2 As shown, the adjustment device is arranged at the feeding end in the material conveying direction, and comprises:

[0087] The silo 12 has an inlet and an outlet arranged therethrough for feeding materials.

[0088] The adjustment components are arranged in the silo 12, and n+1 groups are arranged along the material width direction, and a material guiding channel is formed between adjacent adjustment components.

[0089] There are n material guiding channels, which are respectively arranged in one-to-one correspondence with the transmitting elements and the receiving elements.

[0090] Along the material width direction, two groups of adjustment components located at the edge are respectively arranged close to the inner wall of the silo 12.

[0091] The two groups of adjustment components at the edge are respectively arranged close to the inner wall of the silo 12, so that there is a gap between the two groups of adjustment components at the edge and the inner wall of the silo 12, but no material guiding channel is formed, which is convenient for the adjustment components to adjust the material density in the material width direction.

[0092] The adjustment component comprises:

[0093] The sliding seat is used to adjust the size of the material guide channel.

[0094] The displacement element is connected to the controller at one end and to the sliding seat at the other end, and is used to receive information for adjusting the material density and drive the sliding seat to move.

[0095] The swing plate 21 is connected to the sliding seat and is extended along the material guiding direction.

[0096] The displacement element is a driving cylinder, and the telescopic rod of the driving cylinder is connected to the sliding seat. The sliding seat is driven to move left and right by the telescopic rod, thereby changing the size of the material guiding channel.

[0097] A connecting shaft is arranged on the sliding seat, and the connecting shaft is movably connected to the swing plate 21 to realize the swing of the swing plate 21 .

[0098] The swinging action of the swing plate 21 on the material is beneficial to the efficiency of material feeding and further improves the uniformity of material density in the width direction of the material.

[0099] When n is 3, specifically, Figure 2 and Figure 3 As shown:

[0100] Three emitting elements are provided, which are distributed on the upper knife gate seat 3 along the material width direction, and are respectively a first emitting element 5, a second emitting element 6, and a third emitting element 7.

[0101] Three receiving elements are provided, which are distributed on the lower knife gate seat 4 along the material width direction, and are respectively a first receiving element 8, a second receiving element 9, and a third receiving element 10.

[0102] Four groups of adjustment components are arranged along the material width direction, namely the first adjustment component, the second adjustment component, the third adjustment component and the fourth adjustment component, and there are three corresponding material guide channels. The first material guide channel is formed between the first adjustment component and the second adjustment component, the second material guide channel is formed between the second adjustment component and the third adjustment component, and the third material guide channel is formed between the third adjustment component and the fourth adjustment component.

[0103] Four driving cylinders are provided, namely a first driving cylinder 13 , a second driving cylinder 14 , a third driving cylinder 15 , and a fourth driving cylinder 16 .

[0104] Four sliding seats are provided, namely a first sliding seat 17 , a second sliding seat 18 , a third sliding seat 19 , and a fourth sliding seat 20 .

[0105] Furthermore, the adjustment device also includes:

[0106] The connecting rod 22 is extended along the width direction of the material and connected to each swing plate 21 .

[0107] The driving element 23 is connected to the connecting rod 22 and is used to drive the connecting rod 22 to perform reciprocating periodic motion along the width direction of the material, thereby driving the swing plate 21 to perform reciprocating periodic swing along the width direction of the material.

[0108] In this embodiment, the material is fed from the silo 12, passes through various material guide channels, and reaches the lower conveyor belt 2 under the swing of the swing plate 21. The material is transported along the transmission direction of the upper conveyor belt 1 and the lower conveyor belt 2. When the material is transported to the discharge end, the density of the material in the width direction is detected in real time by the transmitting element on the upper knife gate seat 3 and the receiving element on the lower knife gate seat 4, and is transmitted to the data processing element 11 to be processed into density information. The density information is compared with the preset information. When the material density needs to be adjusted, the controller controls the displacement element to drive the sliding seat to move, change the size of the material guide channel, and realize the density adjustment in the width direction of the material.

[0109] As an implementation scheme, the present invention provides a method for automatically detecting and adjusting the material density of a shredder, which is applied to a shredder as described above.

[0110] The method comprises the following steps:

[0111] S1: Obtain the density value Pi in the width direction of the material conveying, and calculate the density deviation value δi according to the density value Pi;

[0112] S2: Compare the density deviation value δi with the deviation standard value δk, and when the absolute value of the density deviation value δi is greater than the deviation standard value δk, adjust the material density in the material conveying width direction.

[0113] In step S1, when the material is transported to the discharge end, the density value Pi = {P1, ..., Pn} of the material is obtained, Pi is the density value corresponding to the i-th material guide channel, and the density deviation value δi = {δ1, ..., δn} is calculated according to the density value Pi, δi is the density deviation value corresponding to the i-th material guide channel, wherein,

[0114]

[0115] The step S2 also includes determining that when the absolute value of the density deviation value δi is less than or equal to the deviation standard value δk, there is no need to adjust the material density.

[0116] Further, when the absolute value of δi in step S2 is greater than the deviation standard value δk, step S2 includes:

[0117] When δi is a positive value, the size of the i-th material guide channel is controlled to be reduced;

[0118] Alternatively, when it is determined that δi is a negative value, the size of the i-th material guiding channel is controlled to be increased.

[0119] Further, step S2 includes:

[0120] When i=1, when δ1 is judged to be a positive value, the displacement of the first sliding seat is L1=K1*δ1;

[0121] Alternatively, when δ1 is judged to be a negative value, the displacement of the first sliding seat is L1′=K1*δ1.

[0122] The values ​​of L1 and L1' are the same in magnitude but opposite in direction, that is, when the density deviation value of the material guiding channel is positive or negative, the adjustment amount of the corresponding sliding seat is the same, but the displacement direction is opposite.

[0123] When i=n, ​​when δn is judged to be a positive value, the displacement of the n+1th sliding seat is L(n+1)=K(n+1)*δnn;

[0124] Or, when δn is judged to be negative, the displacement of the n+1th sliding seat is L(n+l) i =K(n+1)*δn.

[0125] Among them, K1=-K(n+1).

[0126] That is, when the sizes of the first material guiding channel and the nth material guiding channel are adjusted, if they are both increased or decreased, the movement directions of the first sliding seat and the n+1th sliding seat are opposite.

[0127] Further, step S2 includes:

[0128] When i=m, 2≤m≤n-1, when δm is judged to be a positive value, the displacement of the m-th sliding seat is Lm=Km*δm, and the displacement of the m+1-th sliding seat is L(m+1)=K(m+1)*δm;

[0129] Alternatively, when δm is determined to be a negative value, the displacement of the m-th sliding seat is Lm′=Km*δm, and the displacement of the m+1-th sliding seat is L(m+1)′=K(m+1)*δm.

[0130] Among them, Km=-K(m+1).

[0131] That is, when the mth material guiding channel is adjusted, the mth sliding seat and the (m+1)th sliding seat move simultaneously, and in opposite directions.

[0132] Km<K1, preferably, Km=(0.4~0.6)K1.

[0133] Since the size of the middle material guiding channel will affect the size of the adjacent material guiding channels and / or edge material guiding channels when the size is adjusted, Km is set to be less than K1 to minimize the impact within the error range without changing the original adjustment amount of the adjacent material guiding channels and / or edge material guiding channels.

[0134] When n is 3, specifically:

[0135] When δ1 is judged to be a positive value, it means that there is too much material in the first material guiding channel, and the first driving cylinder extends, and the extension amount is L1=K1*δ1, thereby driving the first sliding seat to move, reducing the size of the first material guiding channel, while the sizes of the second material guiding channel and the third material guiding channel remain unchanged;

[0136] Alternatively, when δ1 is judged to be a negative value, it means that the material in the first material guide channel is too little, and the first driving cylinder retracts by an amount L1, thereby driving the first sliding seat to move, increasing the size of the first material guide channel, while the sizes of the second and third material guide channels remain unchanged.

[0137] When it is judged that δ2 is a positive value, it means that there is too much material in the second material guide channel, then the second driving cylinder extends, the extension amount is L2 = K2 * δ2, and then drives the second sliding seat to move, and at the same time, the third driving cylinder retracts, the retraction amount is L3 = K3 * δ2, and then drives the third sliding seat to move, reducing the size of the second material guide channel, while the sizes of the first material guide channel and the third material guide channel are less affected and do not need to be adjusted;

[0138] Alternatively, when δ2 is judged to be a negative value, it means that the material in the second material guide channel is too little, and the second driving cylinder retracts by an amount L2, thereby driving the second sliding seat to move. At the same time, the third driving cylinder extends by an amount L3, thereby driving the third sliding seat to move, thereby increasing the size of the second material guide channel. At the same time, the sizes of the first material guide channel and the third material guide channel are less affected and do not need to be adjusted.

[0139] When δ3 is judged to be a positive value, it means that there is too much material in the third material guiding channel, and the fourth driving cylinder retracts, and the retraction amount is L4=K4*δ3, thereby driving the fourth sliding seat to move, reducing the size of the third material guiding channel, while the sizes of the first material guiding channel and the second material guiding channel remain unchanged;

[0140] Alternatively, when δ3 is judged to be a negative value, it means that the material in the third material guide channel is too little, and the fourth driving cylinder extends by an amount L4, thereby driving the fourth sliding seat to move, increasing the size of the third material guide channel, while the sizes of the first material guide channel and the second material guide channel remain unchanged.

[0141] In the above embodiments, the number of adjustment components, material guide channels, transmitting elements, receiving elements, etc. can be changed as needed. And the adjustment device can adjust the material density multiple times until the material density in the material conveying width direction reaches the required uniformity.

[0142] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
