Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to a portable installation and wear detection device for a copper sleeve flange of an online continuous vacuum rehumidification machine. Background Art

[0002] In the process of vacuum rehumidification of tobacco leaves, the online continuous vacuum rehumidification machine is used to combine vacuum rehumidification with logistics conveying equipment to form an uninterrupted automatic assembly line. The function of the online continuous vacuum rehumidification machine is to moderately increase the temperature and moisture content of tobacco leaves, remove green and foreign odors, loosen tobacco leaves, kill insect eggs, and provide suitable raw materials for the next process.

[0003] Since the vacuum rehumidification process of tobacco leaves is in a completely vacuum, high temperature, and high humidity working environment, the working vacuum degree under working conditions is ≤666Pa, the working steam pressure is 0.8~1.1MPa, and the relative humidity is ≤80%. One side of the copper sleeve flange is installed on the inner box wall of the vacuum rehumidifier, and the distance between the main drive sprocket on the main drive shaft connected to it on the other side is only 2㎜. Therefore, the wear state of the copper sleeve flange of the vacuum rehumidifier cannot be detected by conventional detection methods containing electrical components and large-scale detection devices. Due to the small space at the site for dismantling the copper sleeve flange of the rehumidifier, there are no corresponding special tools, and it only depends on the personal maintenance skills of the equipment maintenance personnel and the proficiency of equipment disassembly. Therefore, every maintenance work on the copper sleeve flange of the rehumidifier not only has major safety hazards, but also is time-consuming and labor-intensive, increasing production costs and reducing the effective operation rate of the equipment.

[0004] In addition, since the copper sleeve flange and the main drive shaft are both set up with transition fit, the wear between the copper sleeve flange and the main drive shaft will gradually increase with the working time after the copper sleeve flange has been in working state for a certain period of time. Therefore, it is difficult to quickly and effectively detect the wear during normal production. Since the wear of the copper sleeve flange and the degree of wear cannot be detected, the flange and the main drive shaft are damaged destructively, which ultimately causes major equipment failures and major safety hazards. In the prior art, there is no wear detection device for the copper sleeve flange of the rehumidifier. Therefore, there is an urgent need for a device that can conveniently detect the wear and wear condition of the copper sleeve flange of the rehumidifier. Utility Model Content

DETAILED DESCRIPTION

[0030] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0031] See also Figure 1 to Figure 2 It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change in the proportion relationship, or adjustment of the size should still fall within the scope of the technical content disclosed by the utility model without affecting the effects and purposes that can be achieved by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0032] like Figure 1 , Figure 2As shown, the utility model provides a wear detection component 1, which includes: an element sleeve 14 and a marking element 13, wherein the element sleeve 14 is used to fix the marking element 13; when in use, the front end of the marking element 13 is exposed from the element sleeve 14, and the rear end is arranged in the element sleeve 14; the marking element 13 is an element used to make marks on stainless steel.

[0033] In a more specific embodiment, the marking element 13 is a carbon rod. The marking is drawn on the stainless steel shaft by the carbon rod. Since the shaft is rotating, the marking element 13 is stationary, so the marking is a circle.

[0034] When the wear detection assembly 1 as described above is used, if it is set on the flange of the vacuum rehumidification machine, it can mark the stainless steel part (such as the main transmission shaft) that abuts against it through the marking element 13. The operator can judge the degree of wear of the copper sleeve on the flange by observing this mark and its changes. For example, if the mark becomes thicker, it means that the copper sleeve of the flange is gradually worn seriously. Therefore, it can be judged whether to replace it according to the actual working situation. When in use, the marking element 13 is fixed by the element sleeve 14, and the element sleeve 14 can be fixed on the flange.

[0035] In a Figure 2 In the specific embodiment shown, the assembly further includes a spring 12; when in use, the spring 12 is disposed in the element sleeve 14 and abuts against the tail end of the marking element 13. More specifically, the spring 12 is a compression spring in the process of abutting against the marking element 13, so that it can abut against the tail end of the marking element 13 to push the marking element 13 to play a buffering role during the marking wear process, so as to prevent the marking element 13 from being directly broken due to excessive force.

[0036] In a Figure 2 In the specific embodiment shown, the assembly further comprises a sleeve cap 11, which matches and is detachably connected to the tail end of the element sleeve 14. The sleeve cap 11 and the element sleeve 14 are used together to fix the marking element 13 in the element sleeve 14, wherein the tail end of the marking element 13 is blocked by the sleeve cap 11, and the head end of the marking element 13 is exposed from the element sleeve 14.

[0037] In a Figure 2 In the specific embodiment shown, the sleeve cap 11 is a bolt, and the bolt is matched and connected with the element sleeve 14 through a threaded structure. This matching connection is a detachable connection mode. When the marking element 13 needs to be replaced, the sleeve cap 11 can be removed to replace the new marking element 13 and install it in the element sleeve 14.

[0038] In a Figure 1 and Figure 2 In the specific embodiment shown, the exposed portion of the marking element 13 is a cone, and the diameter of the head end of the marking element 13 is the smallest. With this structure of the marking element 13, the diameter of the exposed portion of the cone is smaller than the diameter of the head end of the element sleeve 14, and the unexposed portion of the marking element 13 is limited in the element sleeve 14 by the limiting structure in the element sleeve 14.

[0039] The limiting structure in the element sleeve 14 can be a protruding limiting structure, such as a plurality of protruding limiting blocks; or it can be realized by changing the inner diameter of the element sleeve 14 along the axial direction. Figure 2 In the specific embodiment shown, the inner diameter of the head end of the element sleeve 14 is smaller than the inner diameter of the tail end. The marking element 13 is limited by this diameter change.

[0040] In a more specific embodiment, the inner diameter of the head end of the element sleeve 14 is 1-4 mm, and the inner diameter of the tail end of the element sleeve is 4-8 mm.

[0041] In some specific embodiments of the present invention, the inner diameter of the head end of the element sleeve is 3 mm, and the inner diameter of the tail end is 6 mm.

[0042] like Figure 1 and Figure 2 As shown, the utility model provides a flange for a vacuum rehumidification machine, comprising: a flange 2 and a wear detection assembly 1 as described in any of the above-mentioned specific embodiments, the flange 2 comprising a flange base 21, a flange neck 22 and a flange working hole 24, the flange working hole 24 is a middle hole passing through the flange neck 22 and the flange base 21, and the wear detection assembly 1 is arranged on the flange base 21.

[0043] When the flange for the vacuum rehumidification machine is used, the flange 2 is sleeved on the main transmission shaft 3 of the vacuum rehumidification machine to fix the main transmission shaft 3 to prevent the main transmission shaft 3 from falling off during operation. The wear detection component 1 is fixed on the flange base 21 and can mark the main transmission shaft 3 through the marking element 13. The operator can judge the degree of wear of the copper sleeve on the flange by observing the mark and its changes. Figure 2 In the specific embodiment shown, the exposed portion of the marking element 13 is higher than the height of the flange neck 22. Through this structure of the marking element 13, the exposed portion of the marking element 13 can contact or approach contact with the main transmission shaft 3, thereby leaving a mark during the rotation of the main transmission shaft 3.

[0044] In a Figure 2In the specific embodiment shown, the axial direction of the marking element 13 is arranged parallel to the diameter direction of the flange base 21. By arranging the marking element 13 in this direction, during the rotation of the main transmission shaft 3, the marking element 13 is perpendicular to the rotation direction of the main transmission shaft 3, so that the marking element 13 can more easily leave a mark during the rotation of the main transmission shaft 3.

[0045] In a Figure 2 In the specific embodiment shown, the flange 2 further includes a copper sleeve 23, which is disposed in the flange working hole 24 and fits against the inner wall of the flange working hole 24. In a specific embodiment, the copper sleeve 23 and the flange 2 are detachably connected, such as a transition fit connection; when the copper sleeve 23 is worn and needs to be replaced, only the copper sleeve 23 can be replaced without replacing the flange 2.

[0046] In a more specific Figure 1 In the illustrated embodiment, the head end of the marking element 13 is closer to the working hole of the flange 2 than the tail end of the marking element 13. When in use, the main transmission shaft 3 is located in the working hole of the flange 2, and the head end of the marking element 13 is closer to the main transmission shaft 3, so that the head end of the marking element 13 draws a mark on the main transmission shaft 3.

[0047] In a Figure 2 In the specific embodiment shown, the height of the copper sleeve 23 along the axial direction is consistent with the height of the flange neck 22, thereby avoiding direct contact with the inner wall of the flange 2 during the rotation of the main transmission shaft 3 and achieving the front end of the marking element 13 close to the main transmission shaft 3.

[0048] In a more specific embodiment, the thickness of the flange base is 5-10 mm, the height of the flange neck is 5-15 mm, and the height of the copper sleeve is 10-25 mm.

[0049] In some specific embodiments of the present invention, the thickness of the flange base is 8 mm, the height of the flange neck is 12 mm, and the height of the copper sleeve is 20 mm. Figure 1 or Figure 2 As shown, the utility model provides a specific vacuum rehumidification machine, including: a main transmission shaft 3, a main transmission sprocket 4 and a flange for a vacuum rehumidification machine as described in any of the above embodiments, the main transmission sprocket 4 is sleeved on the middle part of the main transmission shaft 3, and the flange for the vacuum rehumidification machine is sleeved on the tail end of the main transmission shaft 3 through the working hole of the flange 2.

[0050] When the vacuum rehumidification machine as described above is in use, the main transmission sprocket 4 drives the main transmission shaft 3 to rotate, thereby causing the copper sleeve 23 in the flange 2 to gradually wear out. The marking element 13 will continuously draw circles during the rotation of the main transmission shaft 3. The operator can judge the degree of wear of the flange copper sleeve by observing this mark and its changes, and determine whether to replace it according to actual working conditions.

[0051] In a Figure 2 In the specific embodiment shown, the head end of the marking element 13 faces the offset direction of the main transmission shaft 3, so that the wear of the copper sleeve is indirectly detected through the offset distance and degree of the main transmission shaft 3 and the thickness of the circle drawn by the marking element 13 on the main transmission shaft 3. For example, the more severe the force wear of the copper sleeve 23, the more the main transmission shaft will deviate, thereby causing the marking element 13 to draw a thicker circle mark on the main transmission shaft 3. When the operator visually observes that the thickness of the circle mark or the change in thickness has reached a certain value, the copper sleeve 23 can be replaced in time according to the operation situation. The offset direction of the main transmission shaft 3 can be obtained based on actual work.

[0052] In a specific embodiment, the gap between the flange neck 22 and the main drive sprocket 4 is 2-8 mm.

[0053] In some specific embodiments of the utility model, the size of the original WZ193A online continuous vacuum rehumidification machine copper sleeve flange is optimized. The total height of the original flange base 21 and the flange neck 22 is 25mm, and the total height of the flange base 21 and the flange neck 22 after size optimization is 20mm. Specifically, the thickness of the flange base 21 is changed from 10mm to 8mm, the height of the flange neck 22 is changed from 15mm to 12mm, and the height of the copper sleeve 23 is changed from 25mm to 20mm. The distance between the optimized copper sleeve flange neck 22 and the main drive sprocket 4 is expanded from the original 2mm to 7mm, which facilitates the installation and disassembly of the copper sleeve flange 2 and the marking element 13.

[0054] In a specific embodiment, the initial distance between the head end of the marking element 13 and the main transmission shaft 3 is 0-0.3 mm.

[0055] In some specific embodiments of the present invention, the initial distance between the head end of the marking element and the main transmission shaft is 0.1 mm.

[0056] like Figure 1 and Figure 2As shown, the working principle of the utility model is: the online continuous vacuum rehumidification machine re-dries the tobacco leaves, and forms an uninterrupted automatic assembly line through logistics conveying equipment. In this process, the main transmission sprocket 4 near the flange 2 is connected to the reducer chain as a power source to drive the main transmission shaft 3 to rotate, and the working sprocket 5 far away from the flange is connected to the working chain to drive the working chain to operate, so that the cigarette box on the working chain moves linearly with the operation of the working chain, and finally achieves the purpose of transporting the cigarette box in and out of the rehumidification machine box. Since the main transmission shaft 3 will continuously wear the copper sleeve 23 during the rotation process, the main transmission shaft 3 will continuously approach the detection front end of the marking element 13 during the wear and thinning of the copper sleeve. The marking element 13 is made of carbon rod material. When the main transmission shaft 3 rotates close to it, the marking element 13 will leave a mark on the main transmission shaft. The wear of the copper sleeve 23 can be judged according to the thickness of the mark. When the mark reaches 1-2mm, it proves that the copper sleeve 23 needs to be replaced. When replacing, only the copper sleeve 23 and the marking element 13 need to be replaced and the device can be put into use again.

[0057] In summary, the portable installation and wear detection device for the copper sleeve flange of the WZ193A online continuous vacuum rehumidification machine provided in this application can provide efficient, safe, timely and effective information feedback for the wear detection of the copper sleeve flange in the actual production of the WZ193A online continuous vacuum rehumidification machine, thereby avoiding the serious wear of the copper sleeve flange and other transmission components connected to it due to the inability to detect the wear of the copper sleeve flange during the production process, causing destructive damage to the equipment components and ultimately causing major equipment failures and major safety hazards. In addition, during the maintenance process, under limited disassembly operation space, the copper sleeve flange with optimized size can be efficiently and safely removed or installed, avoiding the long equipment maintenance time caused by the small maintenance space and high maintenance skill requirements (each maintenance time is often 1.5 to 2 hours before the transformation, and each maintenance time is often 0.3 to 0.6 hours after the transformation), saving enterprise costs. Therefore, the utility model effectively overcomes the various shortcomings of the prior art and has a high industrial utilization value.

[0058] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
