Description

Technical Field

[0001] The invention relates to the technical field of cotton primary processing, and in particular to a cotton fiber transfer device and equipment and a cotton fiber transfer method. Background Art

[0002] Sawtooth cotton gin, sawtooth lint stripping machine, etc. are core processing equipment in the field of primary processing of cotton. Sawtooth cotton gin and sawtooth lint stripping machine mostly use saw blade roller and brush roller as transfer devices for cotton fibers. However, when the brush roller is working, there are problems such as high working noise, large dust emission, low impurity removal efficiency, and poor cotton fiber morphology. To solve the above problems, the prior art uses a barbed roller instead of the existing brush roller to achieve cotton fiber transfer, which greatly reduces the working noise and dust emission of sawtooth cotton gin, sawtooth lint stripping machine, etc., and greatly improves the impurity removal efficiency.

[0003] However, the cotton fiber can only be completely transferred when the transfer speed ratio of the cotton fiber transfer device is not lower than the preset value. In practical applications, since the rotational tooth ratio of the thorn roller and the saw blade roller is unchanged per unit time, in order to make the transfer speed ratio meet the requirements, it is usually necessary to directly reduce the rotation speed of the saw blade roller, increase the rotation speed of the thorn roller or increase the diameter of the thorn roller. However, directly reducing the rotation speed of the saw blade roller will affect the work efficiency, directly increasing the rotation speed of the thorn roller will affect the safety of the thorn roller, and directly increasing the diameter of the thorn roller will increase the manufacturing cost and operating cost of the thorn roller. Summary of the invention

[0004] Based on this, the main purpose of the present invention is to provide a cotton fiber transfer device and equipment as well as a cotton fiber transfer method that can achieve complete transfer of cotton fibers without affecting work efficiency, operational safety and cost.

[0005] To achieve the above object, the present invention provides a cotton fiber transfer device, comprising:

[0006] A saw blade roller, the saw blade roller comprising a first rotating shaft and a plurality of saw blades, the plurality of saw blades being sleeved on the first rotating shaft at intervals, a plurality of first saw teeth being arranged on the outer periphery of each saw blade, the first rotating shaft being used to drive the saw blades to rotate around the axis of the first rotating shaft, and the cotton fibers of the seed cotton are driven to rotate through the first saw teeth;

[0007] A thorn bar roller, arranged adjacent to the saw blade roller, the thorn bar roller comprises a second rotating shaft, a rotating column and a rack, the rotating column is sleeved on the second rotating shaft, the rack is spirally wound around the outer circumference of the rotating column, a plurality of second saw teeth are arranged on the outer circumference of the rack, the second rotating shaft is parallel to the axis of the first rotating shaft, the second rotating shaft is used to drive the rotating column and the rack to rotate around the axis of the second rotating shaft, and transfer the cotton fibers on the saw blade roller to the thorn bar roller through the second saw teeth, and output the cotton fibers to a desired position, the second rotating shaft rotates in opposite directions to the first rotating shaft, and the linear speed of the thorn bar roller is greater than the linear speed of the saw blade roller;

[0008] The number of teeth of the second saw teeth in each pitch of the rack is greater than a first preset multiple of the number of teeth of the first saw teeth on each saw blade, so that the number of rotating teeth of the second saw teeth in each pitch of the rack per unit time is greater than a second preset multiple of the number of rotating teeth of the first saw teeth on each saw blade per unit time, and the second preset multiple is greater than 1.4 times.

[0009] Preferably, the second preset multiple is 1.4-2.5 times.

[0010] Preferably, the pitch of the second saw teeth is 1.3-7.2 mm.

[0011] Preferably, the tooth length of the second sawtooth is not less than a preset length.

[0012] Preferably, the preset length is 0.58 mm, and the tooth length of the second sawtooth is 0.58-6 mm.

[0013] Preferably, the tooth front angle of the second sawtooth is 5°-30°.

[0014] Preferably, the pitch of the rack on the thorn roller is 0.4-4 mm.

[0015] Preferably, the cotton fiber transfer device also includes ribs, the number of the ribs is one more than the number of the saw blades, and the ribs are arranged on both sides of each saw blade. The ribs are used to block the cotton seeds of the seed cotton when the saw blade hooks the cotton fibers of the seed cotton and drives the cotton fibers to rotate, so as to make the cotton seeds escape from the saw blade roller.

[0016] To achieve the above object, the present invention also provides a cotton fiber transfer device, including the above cotton fiber transfer device.

[0017] To achieve the above object, the present invention also provides a cotton fiber transfer method based on the above cotton fiber transfer device, comprising the following steps:

[0018] Provide seed cotton;

[0019] Starting the saw blade roller and the thorn strip roller, so that the first rotating shaft of the saw blade roller rotates around the axis of the first rotating shaft itself, so as to drive the saw blade to rotate around the axis of the first rotating shaft, and drive the cotton fibers of the seed cotton to rotate through the plurality of first saw teeth on the outer periphery of the saw blade;

[0020] The second rotating shaft of the thorn bar roller is rotated around the axis of the second rotating shaft itself, so as to drive the rotating column and the rack to rotate around the axis of the second rotating shaft, and the cotton fibers on the saw blade roller are transferred to the thorn bar roller through the plurality of second saw teeth on the outer periphery of the rack, and the cotton fibers are output to a desired position;

[0021] Among them, the rotation direction of the second rotating shaft is opposite to that of the first rotating shaft, and the linear speed of the thorn bar roller is greater than the linear speed of the saw blade roller, and the number of teeth of the second saw teeth in each pitch of the rack is more than a first preset multiple of the number of teeth of the first saw teeth on each saw blade, so that the number of rotating teeth of the second saw teeth in each pitch of the rack per unit time is a second preset multiple of the number of rotating teeth of the first saw teeth on each saw blade per unit time, and the second preset multiple is more than 1.4 times.

[0022] The technical solution of the present invention has the following advantages. When the cotton fiber transfer device is working, the first rotating shaft is driven to rotate around its own axis to drive the multiple saw blades to rotate around the axis of the first rotating shaft, so that the cotton fibers of the seed cotton are hooked by the multiple first saw teeth on the outer periphery of each saw blade, and the cotton fibers are driven to rotate. Since the rotation direction of the second rotating shaft is opposite to that of the first rotating shaft, and the linear speed of the pricking roller is greater than the linear speed of the saw blade roller, the hooking and pulling force of the second saw teeth on the cotton fibers is greater than the hooking and pulling force of the first saw teeth on the cotton fibers, so that the pricking roller can transfer the cotton fibers on the saw blade roller to the pricking roller through the second saw teeth, and then the pricking roller outputs the cotton fibers to the desired position. In addition, compared with the prior art in which the rotation tooth number ratio of the pricking roller and the saw blade roller per unit time is unchanged, the present application creatively proposes to set the rotation tooth number ratio to be greater than the second preset multiple, that is, the second saw teeth in each pitch of the rack are in a single The number of rotating teeth within a certain period of time is greater than the second preset multiple of the number of rotating teeth of the first saw tooth on each saw blade within a certain period of time, and the second preset multiple is greater than 1.4 times. The greater the ratio of rotating teeth, the higher the transfer efficiency of cotton fibers. Among them, the ratio of rotating teeth = (the number of teeth of the second saw teeth in each pitch of the rack * the rotation speed of the thorn roller) ÷ (the number of teeth of the first saw teeth on each saw blade * the rotation speed of the saw blade roller). Therefore, in the present application, under the premise that the ratio of rotating teeth remains unchanged, the number of teeth of the second saw teeth in each pitch of the rack is set to greater than the first preset multiple of the number of teeth of the first saw teeth on each saw blade, that is, the ratio of the number of teeth of the second saw teeth in each pitch of the rack to the number of teeth of the first saw teeth on each saw blade is increased, so that the rotation speed of the thorn roller can be reduced without reducing the transfer efficiency of cotton fibers, thereby increasing the transfer speed ratio of the cotton fiber transfer device to achieve complete transfer of cotton fibers.

[0032] like Figure 1-2As shown, a cotton fiber transfer device 100 includes a saw blade roller 110 and a thorn bar roller 120, the saw blade roller 110 includes a first rotating shaft 111 and a plurality of saw blades 112, the plurality of saw blades 112 are sleeved on the first rotating shaft 111 at intervals, and a plurality of first saw teeth 1121 are arranged on the outer periphery of each saw blade 112, the first rotating shaft 111 is used to drive the saw blade 112 to rotate around the axis of the first rotating shaft 111, and drive the cotton fiber 11 of the seed cotton 1 to rotate through the first saw teeth 1121, the thorn bar roller 120 is arranged adjacent to the saw blade roller 110, the thorn bar roller 120 includes a second rotating shaft 121, a rotating column 122 and a rack 123, the rotating column 122 is sleeved on the second rotating shaft 121, the rack 123 is spirally wound on the outer periphery of the rotating column 122, the outer periphery of the rack 123 is provided with a plurality of second saw teeth 1231, the second rotating shaft 121 and the first rotating shaft 111 are arranged. The axis of the second rotating shaft 121 is parallel to that of the first rotating shaft 111, and the second rotating shaft 121 is used to drive the rotating column 122 and the rack 123 to rotate around the axis of the second rotating shaft 121, and transfer the cotton fiber 11 on the saw blade roller 110 to the thorn roller 120 through the second saw tooth 1231, and output the cotton fiber 11 to the desired position. The second rotating shaft 121 rotates in the opposite direction to the first rotating shaft 111, and the linear speed of the thorn roller 120 is greater than the linear speed of the saw blade roller 110. The number of teeth of the second saw tooth 1231 in each pitch of the rack 123 is greater than the first preset multiple of the number of teeth of the first saw tooth 1121 on each saw blade 112, so that the number of rotating teeth of the second saw tooth 1231 in each pitch of the rack 123 per unit time is the second preset multiple of the number of rotating teeth of the first saw tooth 1121 on each saw blade 112 per unit time, and the second preset multiple is greater than 1.4 times.

[0033] When the cotton fiber transfer device 100 is working, the first rotating shaft 111 is driven to rotate around its own axis to drive the plurality of saw blades 112 to rotate around the axis of the first rotating shaft 111, so that the cotton fiber 11 of the seed cotton 1 is hooked by the plurality of first saw teeth 1121 on the periphery of each saw blade 112, and the cotton fiber 11 is driven to rotate. Since the second rotating shaft 121 rotates in the opposite direction to the first rotating shaft 111, and the linear speed of the thorn bar roller 120 is greater than the linear speed of the saw blade roller 110, the hooking force of the second saw teeth 1231 on the cotton fiber 11 is greater than that of the first saw teeth 1121. The first sawtooth 1121 exerts a hooking force on the cotton fiber 11, so that the thorn roller 120 can transfer the cotton fiber 11 on the saw blade roller 110 to the thorn roller 120 through the second sawtooth 1231, and then the thorn roller 120 outputs the cotton fiber 11 to the desired position. In addition, compared with the prior art that the rotation gear ratio of the thorn roller 120 and the saw blade roller 110 per unit time is unchanged, the present application creatively proposes to set the rotation gear ratio to be above the second preset multiple, that is, the second sawtooth 1231 in each pitch of the rack 123 is The number of rotating teeth per unit time is greater than or equal to the second preset multiple of the number of rotating teeth of the first saw tooth 1121 on each saw blade 112 per unit time, and the second preset multiple is greater than or equal to 1.4 times. The greater the ratio of the number of rotating teeth, the higher the transfer efficiency of the cotton fiber 11; wherein, the ratio of the number of rotating teeth = (the number of teeth of the second saw tooth 1231 in each pitch of the rack 123 * the rotation speed of the thorn roller 120) ÷ (the number of teeth of the first saw tooth 1121 on each saw blade 112 * the rotation speed of the saw blade roller 110). Therefore, the present application is based on the premise that the ratio of the number of rotating teeth remains unchanged. The number of teeth of the second saw teeth 1231 in each pitch of the rack 123 is set to be greater than a first preset multiple of the number of teeth of the first saw teeth 1121 on each saw blade 112, that is, the ratio of the number of teeth of the second saw teeth 1231 in each pitch of the rack 123 to the number of teeth of the first saw teeth 1121 on each saw blade 112 is increased, thereby reducing the rotation speed of the thorn roller 120 without reducing the transfer efficiency of the cotton fiber 11, thereby increasing the transfer speed ratio of the cotton fiber transfer device 100 to achieve complete transfer of the cotton fiber 11.

[0034] In this embodiment, the linear speed of the thorn bar roller 120 refers to the linear speed of the circumference corresponding to the outermost end of the second saw tooth 1231 on the thorn bar roller 120, and the linear speed of the saw blade roller 110 refers to the linear speed of the saw blade 112, that is, the linear speed of the circumference corresponding to the outermost end of the first saw tooth 1121 of the saw blade 112.

[0035] Specifically, when the cotton fiber 11 is transferred from the saw blade roller 110 to the thorn bar roller 120, the cotton fiber 11 will contain impurities. However, since the impurities are relatively heavy, the impurities will fall off from the thorn bar roller 120 before the cotton fiber 11, thereby achieving impurity removal of the cotton fiber 11.

[0036] Specifically, when the linear speed of the thorn roller 120 of the cotton fiber transfer device 100 is greater than the linear speed of the saw blade roller 110, the larger the second preset multiple is, the higher the transfer efficiency of the cotton fiber 11 is; the first preset multiple is calculated or obtained by experiment based on the second preset multiple.

[0037] Specifically, refer to Figure 1 The seed cotton 1 refers to cotton, and the seed cotton 1 includes cotton seeds 12 and cotton fibers 11 wrapped outside the cotton seeds 12.

[0038] Furthermore, the second preset multiple is 1.4-2.5 times. Specifically, although theoretically the larger the second preset multiple is, the better, the number of teeth of the second sawtooth 1231 in each pitch of the rack 123 cannot be infinite. Therefore, the second preset multiple cannot be infinite. In addition, as the diameter of the thorn roller 120 changes, the minimum value of the second preset multiple that can achieve complete transfer of the cotton fiber 11 without reducing the transfer efficiency also changes accordingly. The larger the diameter of the thorn roller 120, the smaller the minimum value of the second preset multiple that can achieve complete transfer of the cotton fiber 11 without reducing the transfer efficiency.

[0039] Furthermore, the pitch of the second saw teeth 1231 is smaller than a preset value. Specifically, under the premise that the diameter and the pitch of the thorn roller 120 remain unchanged, the smaller the pitch of the second saw teeth 1231, the greater the number of second saw teeth 1231 in each pitch of the rack 123. In the present embodiment, the number of second saw teeth 1231 in each pitch of the rack 123 of the present application is greater than a first preset multiple of the number of first saw teeth 1121 on each saw blade 112, which is achieved by reducing the pitch of the second saw teeth 1231.

[0040] Furthermore, the tooth pitch of the second saw teeth 1231 is 1.3-7.2 mm. Specifically, since the second saw teeth 1231 have a certain thickness, the tooth pitch of the second saw teeth 1231 must be greater than the thickness of the second saw teeth 1231. Therefore, the tooth pitch of the second saw teeth 1231 cannot be too small.

[0041] Furthermore, the tooth length of the second saw tooth 1231 is not less than a preset length. Specifically, if the tooth length of the second saw tooth 1231 is too small, the second saw tooth 1231 cannot completely pull out the cotton fibers 11 between the tooth gaps of the first saw tooth 1121. Therefore, the tooth length of the second saw tooth 1231 is not less than a preset length to ensure that the second saw tooth 1231 can completely pull out the cotton fibers 11 between the tooth gaps of the first saw tooth 1121, thereby achieving complete transfer of the cotton fibers 11.

[0042] Further, the preset length is 0.58 mm, and the tooth length of the second sawtooth 1231 is 0.58-6 mm. Specifically, according to the requirements of GB / T19819-2005, the hourly output of the sheet is not less than 5 kg. When the output is equal to 5 kg, after many experiments, the tooth length of the second saw tooth 1231 is 0.58 mm, which can just realize the complete transfer of the cotton fiber 11. In addition, the maximum tooth length of the second saw tooth 1231 is not less than the maximum tooth length of the first saw tooth 1121, so that when the first saw tooth 1121 is fully loaded, the cotton fibers 11 between the tooth gaps of the first saw tooth 1121 can be completely pulled out. Based on the requirements of GH / T1084-2012, the tooth length of the first saw tooth 1121 is 2.8-3.2 or 4.5-6 mm. Therefore, the maximum tooth length of the second saw tooth 1231 of the present application is not less than 6 mm. If the tooth length of the second saw tooth 1231 is too long, it is difficult to manufacture and is easily damaged during use. Therefore, the present application sets the tooth length of the second saw tooth 1231 to be no more than 6 mm. In other embodiments, the maximum tooth length of the second saw tooth 1231 may be slightly greater than 6 mm.

[0043] According to the requirements of GB / T19819-2005, the output per piece is not less than 5 kg (meaning that the output per piece is not less than 0.08333 kg = the output per piece is not less than 83.33 g), then the minimum tooth length of the second sawtooth can be calculated as follows: the minimum tooth length of the second sawtooth = the diameter of the cotton fiber * the minimum number of cotton fibers on the first sawtooth = the diameter of the cotton fiber * [the weight of the cotton fiber of a single sawtooth on the first sawtooth ÷ (the volume of a single cotton fiber * specific gravity)];

[0044] Given: the diameter of cotton fiber is 0.02 mm; the diameter of the saw blade is 320 mm, the number of teeth is 300; the saw blade speed is 680 rpm; the specific gravity of cotton fiber is 1.5 g / cm 3 (=1.5g / 1000mm 3 ); the length of cotton fiber is 30mm;

[0045] Therefore, the minimum tooth length of the second sawtooth is calculated to be 0.02*[83.33÷(300*680)÷(3.14*0.01*0.01*30*1.5÷1000)]≈0.02mm*29 roots=0.58mm, and thus when the sheet-hour output is equal to 5 kg, the tooth length of the second sawtooth 1231 is 0.58mm, which can just achieve complete transfer of the cotton fiber 11.

[0046] Further, the tooth front angle of the second sawtooth 1231 is 5°-30°. Specifically, Figure 2The middle tooth front angle is represented by α. If the tooth front angle of the second saw tooth 1231 is too small, such as the tooth front angle is less than 5°, the gripping force of the thorn bar roller 120 on the cotton fiber 11 is weak. During the transfer of the cotton fiber 11, the cotton fiber 11 is easy to break away from the thorn bar roller 120 and be hooked again by the saw blade roller 110, forming recycled cotton, causing loss or damage of the cotton fiber 11; if the tooth front angle of the second saw tooth 1231 is too large, such as the tooth front angle is greater than 30°, the gripping force of the thorn bar roller 120 on the cotton fiber 11 is too large, making it difficult for the cotton fiber 11 to completely break away from the thorn bar roller 120, causing the thorn bar roller 120 to return cotton and damage the cotton fiber 11.

[0047] Further, refer to Figure 1 The cotton fiber transfer device 100 also includes ribs 130. The number of ribs 130 is one more than the number of saw blades 112. Ribs 130 are arranged on both sides of each saw blade 112. The ribs 130 are used to block the cotton seeds 12 of the seed cotton 1 when the saw blade 112 hooks the cotton fibers 11 of the seed cotton 1 and drives the cotton fibers 11 to rotate, so that the cotton seeds 12 are separated from the saw blade roller 110. In this embodiment, the spacing between adjacent ribs 130 is about 3 mm, which is smaller than the size of the cotton seeds 12. Therefore, the cotton seeds 12 cannot pass through the gaps between adjacent ribs 130, and thus cannot rotate with the saw blade 112 together with the cotton fibers 11. Therefore, when the saw blade 112 drives the cotton fibers 11 of the seed cotton 1 to rotate through the first saw teeth 1121, the cotton seeds 12 will be separated from the saw blade 112.

[0048] Further, the pitch of the rack 123 on the thorn roller 120 is 0.4-4 mm. Specifically, Figure 3 The pitch of the middle rack 123 is represented by P. When the saw blade roller 110 is working, the diffusion width of the cotton fiber 11 on the saw blade 112 is about 4-6mm. Therefore, the present application sets the pitch of the rack 123 to be no more than 4mm to ensure that the rack 123 on the thorn roller 120 can hook and pull the cotton fiber 11 on the saw blade 112 to achieve the transfer of the cotton fiber 11. Based on the manufacturing reasons of the rack, the present application sets the pitch of the rack 123 to be no less than 0.4mm.

[0049] Further, refer to Figure 1 A dust removal plate 140 is provided on one side of the thorn bar roller 120 close to the saw blade roller 110, and the dust removal plate 140 is used to separate impurities from the cotton fibers 11. A cotton supporting plate 124 is provided below the dust removal plate 140. The cotton supporting plate 124 is provided below the thorn bar roller 120, and the cotton supporting plate 124 is used to receive the cotton fibers 11 output by the thorn bar roller 120, and then recover the cotton fibers 11 on the cotton supporting plate 124.

[0050] Further, refer to Figure 1 A cover plate 150 is arranged above the thorn strip roller 120, and the cover plate 150 is used to prevent the cotton fibers 11 from returning.

[0051] like Figure 1 As shown, a cotton fiber transfer device includes the above-mentioned cotton fiber transfer device 100. Specifically, the cotton fiber transfer device can be but is not limited to a sawtooth cotton gin, a sawtooth lint stripping machine, a seed cotton gin or a sawtooth lint cleaning machine.

[0052] Specifically, the processing object of the sawtooth cotton gin is seed cotton, and the processing object of the sawtooth delinting machine is cotton seeds. The sawtooth cotton gin is used to strip the cotton fibers on the seed cotton to obtain cotton fibers and leave the cotton seeds of the seed cotton. However, at this time, the seed cotton still has a small amount of shorter cotton fibers. The seed cotton with a small amount of shorter cotton fibers is then processed by the sawtooth delinting machine to strip the small amount of short cotton fibers on the seed cotton to further obtain cotton fibers.

[0053] Further, refer to Figure 1 The cotton fiber transfer device also includes a working box 200, which is used to accommodate the seed cotton 1. The working box 200 is arranged near the saw blade roller 110. Specifically, the saw blade roller 110 can rotate around its own axis and drive the cotton fibers 11 of the seed cotton 1 in the working box 200 to rotate through the first saw teeth 1121.
