Description

Technical Field

[0001] The present invention belongs to the technical field of recycling and processing of silk ingot paper tubes, and relates to a device for removing paper tube labels, in particular to a device for removing labels on the inner wall of silk ingot paper tubes. Background Art

[0002] By attaching the silk ingot information label to the inner wall of the paper tube, a closer association can be established between the label information and the yarn inside the paper tube. When quality problems occur in the subsequent processing of the yarn, the detailed information such as the production batch, production date, and raw material source of the yarn can be quickly and accurately traced by reading the information on the inner wall label, which helps to promptly identify the cause of the problem and take corresponding solutions. On the other hand, after the silk ingot process is completed, directly attaching the label to the inner wall and then performing subsequent packaging and transportation can avoid affecting production efficiency or causing label damage due to improper label position in subsequent operations.

[0003] However, for the recycled silk ingot paper tubes, the labels need to be removed before they can be recycled again, otherwise it will cause interference of multiple label information and the information of the new silk ingot cannot be correctly read.

[0004] However, due to the narrow internal space of the paper tube, in the prior art, the execution components of the automated equipment need to be designed small enough to reach into the inner wall of the paper tube for label removal operations. However, overly small equipment may result in limited power and functions, making it difficult to meet the required force and operation accuracy for label removal. When operating on the inner wall of the paper tube, the operating angle of the equipment is greatly restricted. Since the paper tube is cylindrical, the equipment needs to be able to be flexibly adjusted in the circumferential and axial directions to ensure that the label can be fully covered and removed, but this poses certain difficulties in mechanical structure and control algorithms for automated equipment. A new device for removing labels needs to be proposed. Summary of the Invention

[0005] The purpose of the present invention is to address the above problems and provide a device for removing labels on the inner wall of silk ingot paper tubes.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The device for removing labels on the inner wall of silk ingot paper tubes includes a frame. A clamping device for clamping the silk ingot paper tube is arranged on the frame. The clamping device includes a first clamping part and a second clamping part. A rotation driving mechanism is arranged on the first clamping part. The rotation driving mechanism contacts the silk ingot paper tube after the clamping device clamps the silk ingot paper tube. A hot air gun is arranged above the clamping device.

[0008] In the above-described inner wall labeling device for a de-wired spool paper tube, an image collector is further provided above the clamping device. The image collector is inclined and can collect an image of the inner side wall of the spool paper tube.

[0009] In the above-described inner wall labeling device for a de-wired spool paper tube, the first clamping portion includes a first bracket, and the rotation driving mechanism includes a driving roller shaft.

[0013] In the above-described inner wall labeling device for a de-wired spool paper tube, the second bracket is connected to a mounting frame. At least two guide shafts are provided on the mounting frame. The second bracket is slidably connected to the guide shafts.

[0015] In the above-described inner wall labeling device for a de-wired spool paper tube, a slide table is provided on the machine frame. The hot air gun is fixedly connected to the output end of the slide table through a cantilever frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0027] As Figure 1-2 shown, the device for removing the label on the inner wall of the silk spindle paper tube includes a frame 1. A clamping device 2 for clamping the silk spindle paper tube a is provided on the frame 1. The clamping device 2 includes a first clamping part 3 and a second clamping part 4. A rotation driving mechanism 5 is provided on the first clamping part 3. The rotation driving mechanism 5 contacts the silk spindle paper tube after the clamping device clamps the silk spindle paper tube a. A hot air gun 6 is provided above the clamping device 2.

[0028] When the silk bobbin paper tube a reaches the clamping device 2, the silk bobbin paper tube a is located between the first clamping part 3 and the second clamping part 4. Then, the two clamping parts move towards each other and tightly clamp the paper tube. The rotary drive mechanism 5 rotates the silk bobbin paper tube a to the air outlet of the hot air gun 6. The hot air gun 6 works to blow out hot air. When the high-temperature air acts on the label on the inner wall of the silk bobbin paper tube a, the glue on the label is heated, and its viscosity gradually decreases. Eventually, it loses its viscosity and is blown off from the inner wall of the silk bobbin paper tube a by the hot air.

[0029] In this embodiment, the first clamping part 3 and the second clamping part 4 cooperate with each other to clamp the silk bobbin paper tube a from different positions. Through their combined action, the paper tube is firmly fixed in the device, preventing the paper tube from moving or shaking during the subsequent rotation and label removal processes.

[0030] Preferably, an image collector 7 is further provided above the clamping device 2. The image collector 7 is inclined and can collect the image of the inner side wall of the silk bobbin paper tube a, exposing the entire inner wall of the silk bobbin paper tube a from top to bottom within the collection range of the image collector 7. Then, the rotary drive mechanism 5 drives the silk bobbin paper tube to rotate. After the image collector completely collects the inner wall of the silk bobbin paper tube a and obtains the image of the inner wall of the paper tube, the image is analyzed through an image processing algorithm. Image preprocessing is performed, and steps such as grayscale conversion and filtering denoising are used to improve the image quality. Then, a feature extraction algorithm is used to identify the differential features between the label and the background of the inner wall of the paper tube. Based on these features, the position and range of the label in the image are determined, thereby realizing the positioning of the label.

[0031] The collected image data is transmitted to the image processing system for processing. A preset image processing algorithm is used to analyze the image to identify the position and range of the label. The position information of the label is converted into actual physical coordinates and associated with the positions of the hot air gun 6 and the paper tube. According to the positioning information of the label, the control system drives the rotary drive mechanism 5 to rotate the label to below the air outlet of the hot air gun 6. The hot air gun 6 is accurately aligned with the position where the label is located, and is turned on and off at the appropriate time to achieve precise heating and removal of the label, improving the accuracy and efficiency of label removal, avoiding unnecessary heating of the non-label part by the hot air gun, saving energy and reducing damage to the paper tube.

[0032] Preferably, the first clamping part 3 includes a first bracket 31, and the rotary drive mechanism 5 includes a drive roller shaft 51. The axis of the drive roller shaft 51 is parallel to the axis of the silk bobbin paper tube a clamped by the clamping device 2. When the drive roller shaft 51 rotates, it can drive the paper tube to rotate smoothly through the frictional force with the surface of the paper tube, ensuring that the rotary drive mechanism 5 can effectively drive the paper tube to rotate, avoiding the paper tube from jumping or shaking during the rotation process, and improving the stability and reliability of the label removal process.

[0033] Furthermore, bearings are provided at both ends of the driving roller shaft 51 and rotatably connected to the first bracket 31, reducing the friction when the driving roller shaft 51 rotates and improving the flexibility and efficiency of rotation. The driving roller shaft 51 is connected to a rotary driver 52 through a gear set. The power of the rotary driver 52 is transmitted to the driving roller shaft 51 to achieve the rotary drive of the driving roller shaft 51.

[0034] Furthermore, the gear set includes a first gear and a second gear. The first gear is coaxially and fixedly connected to the driving roller shaft 51, and the second gear is coaxially and fixedly connected to the output shaft of the rotary driver 52. The first gear and the second gear are directly meshed, transmitting the power of the rotary driver 52 to the driving roller shaft 51, and the transmission ratio can be adjusted as needed to achieve different rotational speeds and torque outputs, and improving the space utilization rate and reliability of the device. The rotary driver 52 is arranged on the side of the driving roller shaft 51 away from the second clamping portion 4. Avoiding interference with the second clamping portion 4 ensures the overall compact structure and reasonable layout of the device.

[0035] Preferably, the second clamping portion 4 includes a second bracket 41, and two passive roller shafts 42 are arranged on the second bracket 41, enhancing the clamping stability of the clamping device 2 on the paper tube, ensuring that the paper tube will not shift or shake during rotation, and improving the accuracy and safety of the label removal operation. The axes of the passive roller shafts 42 are parallel to the axis of the spool paper tube a to be clamped. The passive roller shafts 42 move closer to or away from the first clamping portion 3 along with the second bracket 41, and the passive roller shafts 42 are rotatably connected to the bracket. When the second bracket 41 moves closer to the first clamping portion 3, the passive roller shafts 42 and the first clamping portion 3 jointly clamp the paper tube, playing a role in auxiliary support and stabilizing the paper tube. At the same time, the passive roller shafts 42 can rotate passively with the rotation of the paper tube, reducing the resistance to the rotation of the paper tube.

[0036] Furthermore, the second bracket 41 is connected to a mounting frame 43, and at least two guide shafts 44 are arranged on the mounting frame 43. The guide shafts 44 enable the second bracket 41 to slide along a fixed direction, ensuring the linearity and stability of the movement of the second bracket 41. The second bracket 41 is slidably connected to the guide shafts 44, and a pre-tightening spring 45 is sleeved between the mounting frame 43 and the second bracket 41 on the guide shafts 44 to provide a pre-tightening force for the second bracket 41, enabling the passive roller shafts 42 to closely fit the surface of the paper tube and enhancing the clamping effect. A limit block 46 for preventing the second bracket 41 from detaching from the guide shafts 44 is arranged at one end of the guide shafts 44 close to the second bracket 41, improving the safety and reliability performance.

[0037] The mounting bracket 43 is mounted on the frame 1 through the slide rail 47, providing a sliding track for the mounting bracket 43 so that the mounting bracket 43 can move smoothly along the slide rail 47. A clamping driver 48 is also provided on the frame 1. The clamping driver 48 drives the mounting bracket 43 to move closer to or away from the first clamping portion 3 on the slide rail 47, realizing the clamping and releasing actions of the clamping device 2 on the paper tube. The automated operation of the clamping device 2 is achieved, improving the efficiency of clamping and releasing the paper tube, reducing manual intervention, and enhancing the automation level and production efficiency of the entire device.

[0038] A slide table 61 is provided on the frame 1. The moving direction of the slide table 61 is the same as the direction of the spool paper tube a to be clamped. It provides power for the hot air gun 6 to move linearly, enabling the hot air gun 6 to move along the axial direction of the paper tube, effectively shortening the distance from the label, and making the heating area more precise. The hot air gun 6 is fixedly connected to the output end of the slide table 61 through a cantilever frame 62, forming a gooseneck shape for the hot air gun 6, which is easy to reach the bottom of the spool paper tube a without interference.

[0039] A paper tube conveying platform 11 is also provided on the frame 1. A label processing channel 12 communicating with the lumen of the paper tube is provided below the clamping device on the paper tube conveying platform 11. The automated conveying of the paper tube and the centralized processing of the label are realized, improving the continuity and cleanliness of the entire label removal process, reducing the workload of manual cleaning, and enhancing the production efficiency and the cleanliness of the working environment.

Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0041] Although terms such as spool paper tube a, frame 1, paper tube conveying platform 11, label processing channel 12, clamping device 2, first clamping portion 3, first bracket 31, second clamping portion 4, second bracket 41, passive roller shaft 42, mounting bracket 43, guide shaft 44, pre-tightening spring 45, limit block 46, slide rail 47, rotation driving mechanism 5, driving roller shaft 51, rotation driver 52, first gear, second gear, hot air gun 6, slide table 61, cantilever frame 62, image collector 7, etc. are used more in this article, the possibility of using other terms is not excluded.
