Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tobacco processing equipment, and in particular to a hemp fiber removal cover plate assembly and hemp fiber removal equipment. Background Technology
[0002] The hemp fiber removal machine is a key piece of equipment in tobacco processing and re-drying. It is mainly used to remove impurities such as hemp fibers and chemical fibers from tobacco leaves, improving the purity of the tobacco sheets and providing loose, uniform material for subsequent processing. Existing hemp fiber removal machines include a mounting frame, hemp fiber rollers mounted on the frame, and a conveyor belt located at the inlet side of the hemp fiber rollers. The high-speed rotating hemp fiber rollers (such as "cross-shaped" rollers or rollers with stainless steel hooks) adhere to hemp fibers, knots, and other impurities in the tobacco sheets, achieving impurity separation through physical friction or electrostatic adsorption. After the tobacco leaves enter the hemp fiber roller area, impurities are adhered to the roller surface, while the tobacco sheets fall through the gaps between the rollers onto the high-speed conveyor belt, being transported forward to the next process.
[0003] Existing hemp fiber removal machines have the following problems in practical applications: the tobacco leaves are relatively light, and the high-speed rotation of the hemp fiber rollers easily throws the tobacco leaves out of the equipment range. A common solution is to install a sealed cover above the hemp fiber rollers to prevent the tobacco leaves from being thrown out, but this also presents the following problems: the tobacco leaves used in the hemp fiber removal process are highly moist, and condensation will form on the inner wall of the sealed cover during processing. When the condensation accumulates to a certain level, it will drip onto the tobacco leaves, creating a potential process hazard. Utility Model Content
[0004] The purpose of this utility model embodiment is to provide a hemp fiber removal cover plate assembly and hemp fiber removal equipment, which can solve the problems of tobacco leaves being thrown out by the hemp fiber roller and condensate dripping from the cover plate onto the tobacco leaves.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] On the one hand, a hemp fiber removal cover assembly is provided, comprising:
[0007] Mounting bracket, wherein the mounting bracket has a mounting groove, the length of which extends along the X direction;
[0008] Hemp fiber rollers, wherein multiple hemp fiber rollers are installed at intervals along the X direction in the mounting groove, and the rotation axis of the hemp fiber rollers extends along the Y direction;
[0009] A cover plate is connected to the mounting frame on both sides along the Y direction. The cover plate is spaced above the hemp fiber roller and covers the hemp fiber roller. The cover plate has a plurality of through holes spaced apart along its thickness direction. The X direction is perpendicular to the Y direction.
[0010] As a further embodiment of the hemp fiber removal cover assembly, the cover has a structure that is arched in the Z direction toward a direction away from the hemp fiber roller, wherein the X direction, the Y direction, and the Z direction are perpendicular to each other.
[0011] As a further embodiment of the hemp fiber removal cover plate assembly, the cover plate includes a first inclined plate and a second inclined plate arranged at an angle.

The first end and the third end are respectively connected to the two edges of the mounting bracket along the Y direction, and the second end is connected to the fourth end. The height of the second end is higher than that of the first end. The first inclined plate and the second inclined plate are respectively provided with a plurality of through holes along the thickness direction.
[0012] As a further embodiment of the hemp fiber removal cover assembly, the included angle between the first inclined plate and the second inclined plate is 120°-150°.
[0013] As a further embodiment of the hemp fiber removal cover assembly, the distance between the second end and the fourth end and the upper surface of the hemp fiber roller is 30cm-50cm.
[0014] As a further embodiment of the hemp fiber removal cover assembly, the cover has an arc-shaped structure.
[0015] As a further embodiment of the hemp fiber removal cover plate assembly, the cover plate includes a third inclined plate, an arc-shaped plate, and a fourth inclined plate. One end of the third inclined plate along the Y direction is connected to the arc-shaped plate, and the other end of the third inclined plate along the Y direction is connected to one edge of the mounting frame along the Y direction. One end of the fourth inclined plate along the Y direction is connected to the end of the arc-shaped plate away from the third inclined plate, and the other end of the fourth inclined plate along the Y direction is connected to another edge of the mounting frame along the Y direction. The midpoint of the arc-shaped plate along the Y direction is furthest from the hemp fiber roller. The third inclined plate, the arc-shaped plate, and the fourth inclined plate are respectively provided with a plurality of through holes spaced apart along the thickness direction.
[0016] As a further embodiment of the hemp fiber removal cover assembly, the through hole is a round hole with a diameter of 10mm-20mm.
[0017] As a further embodiment of the hemp fiber removal cover assembly, the density of the through holes is 0.1 holes / cm². 2 -1.2 holes / cm 2 .
[0018] On the other hand, a hemp fiber removal device is provided, including the hemp fiber removal cover plate assembly.

[0032] Example 1
[0033] like Figure 1 and Figure 2As shown, the hemp fiber removal cover plate assembly of this embodiment includes a mounting frame 1, hemp fiber rollers 2, and a cover plate 3. The mounting frame 1 has a mounting groove 11, the length of which extends along the X direction; multiple hemp fiber rollers 2 are installed at intervals along the X direction in the mounting groove 11, and the rotation axis of the hemp fiber rollers 2 extends along the Y direction; the cover plate 3 is connected to the mounting frame 1 on both sides along the Y direction, and the cover plate 3 is positioned above the hemp fiber rollers 2 at intervals and covers the hemp fiber rollers 2, and the cover plate 3 has multiple through holes 301 at intervals along its thickness direction, with the X direction perpendicular to the Y direction.
[0034] In this embodiment, a cover plate 3 is installed on the mounting frame 1 and positioned directly above the hemp fiber roller 2, which prevents tobacco leaves from being thrown out by the hemp fiber roller 2. By opening multiple through holes 301 at intervals on the cover plate 3, the hot air generated by the tobacco leaves inside the cover plate 3 is discharged outward through the through holes 301 due to pressure difference, allowing the heat accumulated on the inner wall of the cover plate 3 to dissipate and the moisture to evaporate, preventing condensation from dripping onto the tobacco leaves and affecting their moisture content. Compared with the traditional method where the cover plate is spaced above the mounting frame (where there is a gap between the two ends of the cover plate along the Y direction and the mounting frame, making it easy for tobacco leaves to be thrown out of the cover plate through this gap), since the two ends of the cover plate 3 along the Y direction are tightly connected to the mounting frame 1, there is no phenomenon of tobacco leaves being thrown out of the cover plate 3 by the hemp fiber roller 2.
[0035] In this embodiment, the driving structure of the hemp fiber roller 2 can be a motor. The motor is connected to the hemp fiber roller 2 via a transmission belt, thereby driving the hemp fiber roller 2 to rotate. The rotation speed of the hemp fiber roller 2 can be controlled by the motor. This driving structure and driving principle are conventional techniques in the field and will not be described in detail here.
[0036] Furthermore, the cover plate 3 has an arched structure along the Z direction toward the direction away from the hemp fiber roller 2, which can provide sufficient space for the conveying of tobacco leaves on the hemp fiber roller 2, and the X, Y and Z directions are perpendicular to each other.
[0037] Furthermore, the cover plate 3 includes a first inclined plate 31 and a second inclined plate 32 arranged at an angle. The first inclined plate 31 has a first end and a second end along the Y direction, and the second inclined plate 32 has a third end and a fourth end along the Y direction. The first end and the third end are respectively connected to the two edges of the mounting bracket 1 along the Y direction, and the second end is connected to the fourth end. The height of the second end is higher than that of the first end. The first inclined plate 31 and the second inclined plate 32 are respectively provided with a plurality of through holes 301 along the thickness direction.
[0038] In this embodiment, the first inclined plate 31 and the second inclined plate 32 are installed at an angle on the mounting frame 1, which can prevent the tobacco leaves from being thrown out by the hemp fiber roller 2 while also exerting a certain downward pressure on the tobacco leaves, so that the thrown tobacco leaves can pass through the gap of the hemp fiber roller 2 through the downward pressure.
[0039] Furthermore, the included angle between the first inclined plate 31 and the second inclined plate 32 is 120°-150°. By controlling the included angle between the first inclined plate 31 and the second inclined plate 32 to 120°-150°, the downward pressure of the cover plate 3 on the tobacco leaves thrown out by the hemp fiber roller 2 can be adjusted according to the rotation speed of the hemp fiber roller 2.
[0040] Specifically, the angle between the first inclined plate 31 and the second inclined plate 32 is 135°.
[0041] In this embodiment, the first inclined plate 31 and the second inclined plate 32 are symmetrically arranged. The heights of the first end and the third end are the same, and the heights of the second end and the fourth end are the same. The distance between the second end and the fourth end and the upper surface of the hemp fiber roller 2 is 30cm-50cm. That is, the distance between the highest point of the cover plate 3 and the highest point of the hemp fiber roller 2 is 30cm-50cm. The appropriate distance can enable the cover plate 3 to exert sufficient downward pressure on the thrown tobacco leaves.
[0042] Specifically, the distance between the second and fourth ends and the upper surface of the hemp fiber roller 2 is 40cm.
[0043] In this embodiment, the second end of the first inclined plate 31 is welded and fixed to the fourth end of the second inclined plate 32, and the first end of the first inclined plate 31 and the third end of the second inclined plate 32 are welded and fixed to the two edges of the mounting frame 1 along the Y direction, which can improve the installation stability of the cover plate 3.
[0044] In another preferred embodiment of the present invention, the second end of the first inclined plate 31 is hinged to the fourth end of the second inclined plate 32, the first end of the first inclined plate 31 and the third end of the second inclined plate 32 are respectively hinged to the two edges of the mounting frame 1 along the Y direction, and both the first inclined plate 31 and the second inclined plate 32 are telescopic structures, so as to adapt to mounting frames 1 of various sizes.
[0045] Furthermore, the first inclined plate 31 and the second inclined plate 32 have the same structure, both including at least two telescopic parts (not shown in the figure). Taking the first inclined plate 31 as an example, the two adjacent telescopic parts of the first inclined plate 31 are slidably engaged along the inclination direction of the first inclined plate 31 by a sliding structure and are restricted from separating from each other by a limiting structure.
[0046] For example, in two adjacent telescopic parts, one telescopic part has a groove on one side along its thickness direction, and the other telescopic part has a corresponding slider. The sliding connection between the two adjacent telescopic parts is achieved by the cooperation of the slider and the groove. A limiting block is provided at one end of the groove near the other telescopic part, which can prevent the slider from sliding out of the groove and separating.
[0047] The slider can be trapezoidal or I-shaped, and the shape of the groove corresponds to the slider, thereby preventing the slider and the groove from separating in a direction perpendicular to the telescopic part.
[0048] The aforementioned sliding structure and limiting structure are conventional technologies in this field, and will not be described in detail further.
[0049] Furthermore, the through hole 301 is a round hole with a diameter of 10mm-20mm, preferably 15mm. By designing a suitable hole diameter, tobacco leaves can be prevented from being thrown out through the through hole 301, while the cover plate 3 has sufficient heat dissipation effect to prevent dripping from the cover plate 3.
[0050] In this embodiment, the density of the through-hole 301 is 0.1 holes / cm³. 2 -1.2 holes / cm 2 Preferably, the aperture ratio is 0.2 pores / cm. 2 -0.6 pores / cm 2 More preferably 0.3 pores / cm 2 By setting an appropriate pore density, the cover plate 3 can be made to have sufficient heat dissipation effect and prevent dripping from the cover plate 3.
[0051] Example 2
[0052] This embodiment is basically the same as the first embodiment described above, except for the shape of the cover plate 3.
[0053] like Figure 3 As shown, the cover plate 3 has an arc-shaped structure, and the midpoint of the cover plate 3 along the Y direction is furthest from the hemp fiber roller 2. In the above embodiment, the cover plate 3 is composed of a first inclined plate 31 and a second inclined plate 32. Impurities and dust will accumulate at the connection between the two, creating a cleaning dead corner. In this embodiment, the cover plate 3 is designed as an arc-shaped structure, making the entire cover plate 3 very easy to clean.
[0054] Example 3
[0055] This embodiment is basically the same as the first embodiment described above, except for the shape of the cover plate 3.
[0056] like Figure 4 As shown, the cover plate 3 includes a third inclined plate 33, an arc-shaped plate 34, and a fourth inclined plate 35. One end of the third inclined plate 33 along the Y direction is connected to the arc-shaped plate 34, and the other end of the third inclined plate 33 along the Y direction is connected to one edge of the mounting frame 1 along the Y direction. One end of the fourth inclined plate 35 along the Y direction is connected to the end of the arc-shaped plate 34 away from the third inclined plate 33, and the other end of the fourth inclined plate 35 along the Y direction is connected to another edge of the mounting frame 1 along the Y direction. The midpoint of the arc-shaped plate 34 along the Y direction is furthest from the hemp fiber roller 2. The third inclined plate 33, the arc-shaped plate 34, and the fourth inclined plate 35 are respectively provided with multiple through holes 301 spaced apart along the thickness direction. In this embodiment, the cover plate 3 adopts this structural design, which can increase the included angle between the arc-shaped plate 34 and the third inclined plate 33 and the fourth inclined plate 35, thereby improving the ease of cleaning the cover plate 3.
[0057] Furthermore, the third inclined plate 33 and the fourth inclined plate 35 are symmetrical with respect to the arc-shaped plate 34. The two ends of the third inclined plate 33 along the Y direction are respectively hinged to the arc-shaped plate 34 and the mounting frame 1, and the two ends of the fourth inclined plate 35 along the Y direction are respectively hinged to the arc-shaped plate 34 and the mounting frame 1. The third inclined plate 33 and the fourth inclined plate 35 can be designed as telescopic structures, specifically the same as the structure of the first inclined plate 31 and the second inclined plate 32 in the above embodiment, to accommodate more sizes of hemp fiber removal equipment, which will not be described in detail here.

[0059] This embodiment provides a hemp fiber removal device, such as... Figure 5 As shown, the hemp fiber removal cover plate assembly of the above embodiment 1 is included. The hemp fiber removal equipment also includes a first conveyor belt 4 and a second conveyor belt. The first conveyor belt 4 is located on one side of the mounting frame 1 along the X direction and is used to convey tobacco leaves onto the hemp fiber roller 2. The second conveyor belt (not shown in the figure) is located in the mounting groove 11 of the mounting frame 1 and is spaced below the hemp fiber roller 2. It is used to receive the tobacco leaves after removing the hemp fibers and convey the tobacco leaves out.
[0060] The driving structure for the first conveyor belt 4 and the second conveyor belt can be a motor, which will not be described in detail here.
[0061] In other embodiments, the hemp fiber removal cover plate assembly included in the hemp fiber removal device of this embodiment has the same structure as the hemp fiber removal cover plate assembly of Embodiment 2 or Embodiment 3 above, and will not be shown in detail again.
