Description

Technical Field

[0001] The utility model relates to the technical field of tobacco shred processing, in particular to an angle-adjustable material pile-finding photoelectric tube installation device. Background Art

[0002] Temporary storage cabinets are common equipment in silk-making workshops. They connect materials between upstream and downstream processes and balance material flow, making them widely used on silk-making production lines. During silk production, the proper material placement height within the temporary storage cabinet is crucial. If the material placement height is too high, it can cause material blockages, leading to machine downtime and material interruptions. If the material placement height is too low, it can lead to insufficient material flow to downstream processes, causing flow fluctuations. In practice, due to the specific material placement method and material structure, temporary storage cabinets in silk-making workshops generally use a pile-finding method. The search for piled material mainly relies on the cooperation of the high-level photoelectric tube and the low-level photoelectric tube on both sides of the temporary storage cabinet to control the material distribution of the distribution cart. The control process is as follows: the low-level photoelectric tube is used to monitor whether the distribution cart is positioned, and the high-level photoelectric tube is used to detect whether the height of the tobacco material is in place; specifically, when the low-level photoelectric tube senses that the distribution cart is in place, and the high-level photoelectric tube does not sense that the material is in place, the distribution cart will distribute the material in place; when the low-level photoelectric tube senses that the distribution cart is in place and the high-level photoelectric tube senses that the material is in place, the distribution cart will move back one step to search for piled material; when the low-level photoelectric tube does not sense that the distribution cart is in place and the high-level photoelectric tube does not sense that the material is in place, the distribution cart will move forward one step to search for piled material; therefore, the distribution situation of the temporary storage cabinet is mainly related to the height between the photoelectric tube and the distribution cart and the detection accuracy of the low-level photoelectric tube.

[0003] Currently, the low-level photoelectric tube used to control the feeding of the material distribution cart is installed in the middle of a fixed crossbar. One end of the fixed crossbar is connected to the inner wall of the temporary storage cabinet. The area below the fixed crossbar is the path of the material distribution cart. Although the low-level photoelectric tube in this position can control the feeding process of the material distribution cart to a certain extent, it still has the following defects in actual use:

[0004] (1) Since the fixed horizontal bar installed on the low-level photoelectric tube is at the same height as the material distribution trolley, tobacco is easily hung on the photoelectric tube during the material distribution process, causing the photoelectric tube to mis-sensing, affecting the normal stepping action of the material distribution trolley, causing the material to be too high, resulting in material blocking;

[0005] (2) During the maintenance of the photoelectric tube equipment, it is common for the angle position of the photoelectric tube to shift or the angle of the photoelectric tube to not meet the actual production conditions. In order to ensure the detection accuracy and precision, the angle position of the photoelectric tube needs to be adjusted according to the actual production. The existing method is to adjust the angle of the photoelectric tube by directly pressing or lifting the mounting assembly between the photoelectric tube and the horizontal bar. However, there is no angle reference benchmark in the angle adjustment, and the adjustment accuracy is low.

[0006] Therefore, it is necessary to improve and design the photoelectric tube installation structure on the temporary storage cabinet to solve the problem of low practicality of the photoelectric tube installation structure during the cloth trolley's cloth-making process in the silk-making workshop, because the photoelectric tube installation structure cannot be adjusted according to the actual cloth demand of the cloth trolley. Utility Model Content

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] An angle-adjustable material pile-finding photoelectric tube installation device comprises a support frame, an angle adjustment assembly, an adjustment cross bar, and a photoelectric tube installation assembly; the two fixed ends of the angle adjustment assembly are respectively connected to one end of the support frame; the two adjustment ends of the angle adjustment assembly are respectively connected to the two ends of the adjustment cross bar; the photoelectric tube installation assembly is detachably connected to the adjustment cross bar, and the photoelectric tube installation assembly has a mounting portion for mounting the photoelectric tube.

[0010] Furthermore, the support frame includes a connecting plate and a support arm; the side wall of the connecting plate is provided with a first threaded hole for connecting to the baffles on both sides of the fabric end of the temporary storage cabinet, one side wall of the connecting plate is connected to the first end of the support arm, and the second end of the support arm is detachably connected to the fixed end of the angle adjustment assembly through a bolt assembly.

[0011] Furthermore, the angle adjustment assembly includes a connecting plate, an adjusting plate and an adjusting pin; the boss of the connecting plate is detachably connected to the second end of the support arm through a bolt assembly, and the first pin hole opened on the connecting plate is adjustably connected to the second pin hole opened on the adjusting plate through the adjusting pin, and the side walls of the two adjusting plates are respectively connected to the two ends of the adjusting cross bar.

[0012] Furthermore, there are at least twelve first pin holes distributed in a circular pattern along the side wall of the connecting plate, and the angle between two adjacent first pin holes is 30°.

[0013] Furthermore, there are at least twelve second pin holes distributed in a ring shape along the side wall of the adjustment disk, and the angle between two adjacent second pin holes is 30°.

[0014] Furthermore, the photoelectric tube mounting assembly includes a first half clamp, a second half clamp and a photoelectric tube mounting plate; the first half clamp and the second half clamp are connected to form a complete clamp by a second bolt assembly, the clamp is socketed with the adjustment cross bar, the outer side wall of the second half clamp in the clamp is respectively connected to the two photoelectric tube mounting plates, and the inner side wall of the photoelectric tube mounting plate is the mounting part of the photoelectric tube.

[0015] Furthermore, the edges of the connecting disk and the adjusting disk are rounded.

[0016] During the working process, when adjusting the position of the low-material-level photoelectric tube, the height of the support frame can be changed in time according to the height between the low-material-level photoelectric tube and the material distribution trolley, so that the height of the low-material-level photoelectric tube on the photoelectric tube installation assembly is higher than the horizontal end surface of the material distribution trolley, to prevent tobacco from hanging on the photoelectric tube, causing the photoelectric tube to sense incorrectly and affecting the normal stepping action of the material distribution trolley;

[0017] When performing maintenance and adjustment on the photoelectric tube equipment, the adjusting ends of the two angle adjustment components can be adjusted to the required angle according to the angle of the photoelectric tube that needs to be adjusted, so that the adjusting cross bar connected to the adjusting ends of the two angle adjustment components drives the photoelectric tube installation group on which the photoelectric tube is installed to rotate to an angle that is convenient for maintenance. The maintenance personnel can then perform maintenance and repair on the photoelectric tube equipment to improve the practicality of the equipment.

[0019] 1.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] Example

[0031] Currently, the low-level photoelectric tube used to control the feeding of the material distribution trolley is installed in the middle of the fixed crossbar. One end of the fixed crossbar is connected to the inner wall of the temporary storage cabinet. The area below the fixed crossbar is the path of the material distribution trolley. Although the low-level photoelectric tube in this position can control the feeding process of the material distribution trolley to a certain extent, it still has the following defects in actual use:

[0032] (1) Since the fixed horizontal bar installed on the low-level photoelectric tube is at the same height as the material distribution trolley, tobacco is easily hung on the photoelectric tube during the material distribution process, causing the photoelectric tube to mis-sensing, affecting the normal stepping action of the material distribution trolley, causing the material to be too high, resulting in material blocking;

[0033] (2) During the maintenance of the photoelectric tube equipment, it is common for the angle position of the photoelectric tube to shift or the angle of the photoelectric tube to not meet the actual production conditions. In order to ensure the detection accuracy and precision, the angle position of the photoelectric tube needs to be adjusted according to the actual production. The existing method is to adjust the angle of the photoelectric tube by directly pressing or lifting the mounting assembly between the photoelectric tube and the horizontal bar. However, there is no angle reference benchmark in the angle adjustment, and the adjustment accuracy is low.

[0034] Therefore, the present application proposes an angle-adjustable material pile-finding photoelectric tube installation device to solve the problem of poor practicality of the photoelectric tube installation structure during the cloth trolley's cloth-making process in the silk-making workshop, because the photoelectric tube installation structure cannot be adjusted according to the actual cloth demand of the cloth trolley.

[0036] In actual use, when adjusting the position of the low-material-level photoelectric tube, the support frame 1 of different heights can be replaced in time according to the height between the low-material-level photoelectric tube and the material distribution trolley, so that the height of the low-material-level photoelectric tube on the photoelectric tube installation assembly is higher than the horizontal end surface of the material distribution trolley, so as to prevent tobacco from hanging on the photoelectric tube, causing the photoelectric tube to sense incorrectly and affecting the normal stepping action of the material distribution trolley;

[0037] When performing maintenance and adjustment on the photoelectric tube equipment, the adjusting ends of the two angle adjustment components 2 can be adjusted to the required angle according to the angle that the photoelectric tube needs to be adjusted, so that the adjustment cross bar 3 connected to the adjusting ends of the two angle adjustment components 2 drives the photoelectric tube installation component 4 on which the photoelectric tube is installed to rotate to an angle that is convenient for maintenance. The maintenance personnel can then perform maintenance and repair on the photoelectric tube equipment, thereby improving the practicality of the equipment.

A limiting hole 1 that passes through the internal cavity of the support sleeve arm is provided on the two outer walls of the support sleeve arm, and a number of limiting holes 2 arranged at intervals are provided on the support arm. The limiting hole 1 on the outer wall of the support sleeve arm is movably adjusted through the pin and the limiting hole 2 provided on the support arm.

[0044] Specifically, the boss 12 of the connecting plate 9 is detachably connected to the second end of the support arm 6 through a bolt assembly 8, and the first pin hole 13 opened on the connecting plate 9 is adjustably connected to the second pin hole 14 opened on the adjusting plate 10 through the adjusting pin 11, and the side walls of the two adjusting plates 10 are respectively connected to the two ends of the adjusting cross bar 3.

[0045] In actual use, when the angle adjustment component 2 adjusts the rotation angle of the adjustment cross bar 3, the pin 11 connecting the connecting disk 9 and the adjusting disk 10 can be removed, and then the adjusting disk 10 is rotated along the surface circumference of the connecting disk 9 to the required adjustment angle according to the angle to be adjusted by the adjusting disk 10, so that the second pin hole 14 on the adjusting disk 10 is aligned with the first pin hole 13 on the connecting disk 9, and then the pin 11 is inserted into the second pin hole 14 on the adjusting disk 10 and the first pin hole 13 on the connecting disk 9. In this way, while the adjusting disk 10 is adjusting its angle, the adjusting cross bar 3 connected to the adjusting disk 10 is also adjusted to a certain angle, thereby completing the adjustment process of the rotation angle of the adjusting cross bar 3 by the angle adjustment component 2.

[0046] See also Figure 3 、 Figure 4 and Figure 5 When the angle adjustment assembly 2 adjusts the rotation angle of the adjustment cross bar 3, in order to facilitate the maintenance personnel to accurately position the adjustment of the adjustment cross bar, at least twelve first pin holes 13 are distributed in a ring shape along the side wall of the connecting disk 9, and the angle between two adjacent first pin holes 13 is 30°; and at least twelve second pin holes 14 are distributed in a ring shape along the side wall of the adjustment disk 10, and the angle between two adjacent second pin holes 14 is 30°.

[0048] See also Figure 3 and Figure 6To facilitate assembly of the photoelectric tube mounting assembly and the adjustment cross bar 3, the photoelectric tube mounting assembly 4 includes a first half clamp 15, a second half clamp 16, and a photoelectric tube mounting plate 17; wherein, the first half clamp 15 and the second half clamp 16 are combined to form a complete clamp, which is used to be sleeved with the adjustment cross bar 3 to achieve an adjustable connection between the photoelectric tube mounting assembly 4 and the adjustment cross bar 3; the photoelectric tube mounting plate 17 is used to install the photoelectric tube and to be connected to the bottom of the complete clamp.

[0049] Specifically, the first half clamp 15 and the second half clamp 16 are connected to form a complete clamp by a second bolt assembly 18. The clamp is socketed with the adjusting cross bar 3. The outer side walls of the second half clamp 16 in the clamp are respectively connected to two photoelectric tube mounting plates 17. The inner side walls of the photoelectric tube mounting plates are the mounting parts of the photoelectric tubes.

[0050] In actual use, when the photoelectric tube mounting assembly 4 is assembled with the adjusting cross bar 3, the first half clamp 15 and the second half clamp 16 can be jointly sleeved on the adjusting cross bar 3, and then the first half clamp 15 and the second half clamp 16 are defined as a complete clamp sleeved on the adjusting cross bar 3 using the second bolt assembly 18. Then, the photoelectric tube is installed on the inner side wall of the photoelectric tube mounting plate through the bolt assembly to complete the assembly process of the photoelectric tube mounting assembly and the adjusting cross bar 3.

[0052] In actual use, when other foreign objects touch the connecting disk 9 and the edge 10 of the adjusting disk, the edges of the connecting disk 9 and the adjusting disk 10 are not easily damaged due to the rounded corners, thereby extending the service life of the connecting disk 9 and the adjusting disk 10.

[0053] The present application integrates a support frame, an angle adjustment component, an adjustment cross bar and a photoelectric tube installation component into an angle-adjustable photoelectric tube installation device. When adjusting the height of the low-material-level photoelectric tube and the small cloth workshop, the height of the support frame can be adjusted in time or support frames of different heights can be replaced.
