[0002] The fiber optic tube produced in the secondary sheathing process of the optical cable production process is the main component of the optical cable. It is formed by extruding a layer of plastic sheath through an extruder for the optical fiber and the filling fiber paste and then cooling it with water. During the extrusion process, bulges often occur on the surface of the tube due to impurities, poor plasticization, disconnection, failures of the extruder or the fiber paste filling machine, etc. If the bulge problem is not detected in time, it will bring major quality hazards to the subsequent processes.

[0003] In order to solve the problem of detecting the bulge of the tube, the commonly used adjusting mechanisms in the prior art are mainly divided into a pure mechanical type and a non-contact infrared detection device. However, the pure mechanical adjusting mechanism has problems such as a single adjusting aperture, the need to replace the detection card board when detecting tubes with different apertures, cumbersome operation, and easy breakage of the tube, and the non-contact infrared detection device may have false alarm situations.

[0028] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the accompanying drawings of the specification.

[0029] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0030] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an independent or selectively exclusive embodiment from other embodiments.

[0031] Embodiment 1

[0032] Referring to Figures 1 to 5 , this is the first embodiment of the present utility model. This embodiment provides an adjustment mechanism that can adjust the bundle tubes with different apertures, and it is not necessary to replace the detection card board when detecting bundle tubes with different apertures.

[0033] Specifically, the limiting unit 100 includes a bearing assembly 101, an opening and closing assembly 102 disposed on the upper side of the bearing assembly 101, a positioning assembly 103 fixedly connected to the opening and closing assembly 102, and an adjustment assembly 104 disposed on the upper side of the positioning assembly 103;

[0034] The measuring unit 200 includes a transmission assembly 201 disposed outside the adjustment assembly 104, and a rotating assembly 202 disposed outside the transmission assembly 201.

[0035] It should be noted that the opening and closing assembly 102, the positioning assembly 103, and the adjustment assembly 104 are symmetrically disposed at both ends of the top of the bearing assembly 101. The opening and closing assembly 101 is fixedly connected to the positioning assembly 103, and the positioning assembly 103 is fixedly connected to the adjustment assembly 104.

[0036] During use, the staff fixes the bearing component 101, judges the size of the tube diameter of the bundle tube, selects a suitable opening and closing component 102 so that the opening and closing component 102 can be adapted to the tube diameter of the bundle tube. The positioning component 103 fixes the opening and closing component 102, and adjusts the height of the opening and closing component 102 by adjusting the movement of the adjustment component 104, so that the opening and closing component 102 can be at the same height as the bundle tube. When a bulge appears on the bundle tube, the outer diameter of the bundle tube is larger than the size of the opening and closing component 101, forming a thrust force on both sides of the opening and closing component 101, pushing the positioning component 103 to move to both sides. The movement of the positioning component 103 drives the movement of the adjustment component 104. The movement of the adjustment component 104 causes the transmission component 201 fixedly connected to the bottom of the adjustment component 104 to start moving. The movement of the transmission component 201 drives the rotation component 201 to rotate towards the edge of the bearing component 101. After the bulge of the bundle tube passes through the opening and closing component 102, the opening and closing component 102 loses the thrust force and resets to the original position. The movement of the opening and closing component 102 drives the positioning component 103 to reset to the original position, and at the same time drives the adjustment component 104 to reset to the original position. The movement of the adjustment component 104 drives the transmission component 201 to reset to the original position. The movement of the transmission component 201 drives the rotation component 202 to reset to the original position.

[0037] In summary, the beneficial effect of an adjustment mechanism is that it can adapt to bundle tubes with different diameters by adjusting the semi-circular grooves 102b with different sizes on the mold 102a, expanding the scope of application, so that bundle tubes with different diameters can all use this mechanism for detection. Through the cooperation of the manual knob 104g, the wire shaft 104d and the synchronous belt 104f, when the semi-circular groove 102b is at different heights, the slider 104a is lifted or lowered to a suitable height to cooperate with the bundle tube, and the detection card board does not need to be replaced when detecting bundle tubes with different diameters.

[0038] Embodiment 2

[0039] Refer to Figures 1 to 5 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an adjustment mechanism that can adjust bundle tubes with different diameters, and the detection card board does not need to be replaced when detecting bundle tubes with different diameters.

[0040] Further, the bearing assembly 101 includes a base 101a, first support plates 101b disposed on both side edges of the base 101a, adjusting rods 101c disposed on one side of the first support plates 101b, and guide wheels 101d disposed on one side of the adjusting rods 101c. Among them, one end of the bottom of the first support plate 101b is fixedly connected to the top of the base 101a. One end of the adjusting rod 101c is fixedly connected with a rotating pin. A section of thread is provided on the side of the rotating pin close to the adjusting rod. Before detection, the staff screws out the rotating pin by a certain distance, so that the adjusting rod 101c rotates around the rotating pin. After rotating to the appropriate angle, the rotating pin is further tightened. During the detection process, the adjusting rod 101c is fixedly connected to the first support plate 101b through the rotating pin, and the guide wheel 101d is fixedly connected to the other end of the adjusting rod 101c.

[0041] Further, the opening and closing assembly 102 includes a mold 102a disposed outside the bundle tube, and semi-circular grooves 102b disposed on both side edges of the mold 102a. Among them, the diameter size of the semi-circular groove 102b is selected to match the size of the bundle tube, and 0.2 mm should be added on the basis of the bundle tube size.

[0042] Further, the positioning assembly 103 includes positioning blocks 103a symmetrically disposed outside the opening and closing assembly 102. Among them, grooves are opened at both ends of the positioning block 103a close to the mold 102a. The inner diameter size of the groove is adapted to the outer diameter size of the positioning block 103a, and the mold 102a is fixedly connected to the positioning block 103a.

[0043] Further, the adjustment assembly 104 includes a slider 104a disposed on one side of the positioning block 103a, a set of fixing rods 104b penetrating through the inside of the slider 104a, I-shaped fixing plates 104c disposed at both ends of the fixing rods 104b, a lead screw 104d penetrating through the centers of the I-shaped fixing plates 104c at both ends, a set of limit grooves 104e disposed on the top of the base 101a, the I-shaped fixing plates 104c are slidably disposed inside the limit grooves 104e, a synchronous belt 104f disposed outside the lead screw 104d, and a manual knob 104g disposed at one end of the lead screw 104d. Among them, the adjustment assembly 104 is symmetrically disposed on both sides of the mold assembly 101. The slider 104a is fixedly connected to one side of the positioning block 103a. The fixing rods 104b are slidably connected to the slider 104a. Both sets of I-shaped fixing plates 104c are fixedly connected to both ends of the fixing rods 104b. The lead screw 104d is disposed between the two fixing rods 104b and penetrates through the I-shaped fixing plates 104c at both ends. The manual knob 104g is fixedly connected to the top of the lead screw 104d. Rotating the manual knob 104g drives the synchronous belt 104f to move. The movement of the synchronous belt 104f drives the two lead screws 104d to rotate synchronously and in the same direction. The rotation of the lead screw 104d drives the up and down movement of the sliding block 104a.

[0044] It should be noted that synchronous pulleys are fixedly connected to the tops of both sets of spools 104d. A synchronous belt 104f is sleeved in the middle grooves of the two sets of synchronous pulleys, and the synchronous belt 104f is made of an elastic material. The elastic limit of the synchronous belt 104f is greater than or equal to the sum of the moving distances of the bottoms of the two I-shaped fixing plates 104c in the limit grooves 104e. When a manual knob 104f is rotated to drive one set of spools 104d to rotate, the synchronous belt 104f is driven in the middle grooves of the two sets of synchronous pulleys, causing the other set of spools 104d to rotate synchronously.

[0045] Furthermore, the transmission assembly 201 includes a transmission rack 201a disposed at the bottom of the I-shaped fixing plate 104c, a first transmission gear 201b meshing with the transmission rack 201a, a fixing column 201c disposed on the top of the bearing assembly 101, the fixing column 201c being sleeved with the first transmission gear 201b, a limiting shaft 201d disposed on the top of the bearing assembly 101, a second transmission gear 201e disposed on the outer side of the limiting shaft 201d, and a rotating shaft 201f disposed on the outer side of the limiting shaft 201d; the first transmission gear 201b meshes with the second transmission gear 201e. Among them, the transmission rack 201a is fixedly connected to the outer side wall of the I-shaped fixing plate 104c. The first transmission gear 201b is disposed at the lower end of the fixing column 201c and meshes with the transmission rack 201a. The movement of the transmission rack 201a drives the rotation of the first transmission gear 201b. The rotation of the first transmission gear 201b drives the rotation of the second transmission gear 201e. The rotation of the second transmission gear 201e drives the rotation of the limiting shaft 201d. The rotation of the limiting shaft 201d drives the rotation of the outer rotating shaft 201f.

[0046] Furthermore, the rotating assembly 202 includes a baffle 202a disposed on the outer side of the rotating shaft 201f, a support column 202b disposed on one side of the baffle 202a, and a return spring 202c with both ends fixedly connected to the baffle 202a and the support column 202b respectively. Among them, the baffle 202a is fixedly connected to the rotating shaft 201f. The rotating shaft 201f drives the baffle 202a to rotate and approach the position where the support column 202b is located, providing pressure to the return spring 202c, causing the return spring 202c to be deformed under the force and contract. When the return spring 202c loses the pressure, it converts the pressure into elastic force to push the baffle 202a back to the initial position.

[0047] During use, select a suitable semi-circular groove 102b, and combine the mold 102a provided with the semi-circular groove 102b to form a closed round hole. Insert the mold 102a into the inside of the positioning block 103a until the threaded holes on the mold 102a and the positioning block 103a are concentric. Fix the mold 102a and the positioning block 103a with bolts. When the height of the semi-circular groove 102b does not match the height of the bundle tube, rotate the manual knob 104g to drive the wire shaft 104d to rotate. Through the transmission of the synchronous belt 104f, the two wire shafts 104d rotate simultaneously. The slider 104a threadedly connected to the wire shaft 104d rises and falls to a suitable height under the limitation of the two fixed rods 104b. After the adjustment is completed, place the bundle tube in the groove provided by the guiding wheel 101d, and make the bundle tube pass through the round hole formed by the semi-circular groove 102b and enter the groove provided by the other guiding wheel 101d to complete the assembly before detection.

[0048] When a bulge appears in the bundle tube, when the bulge passes through the round hole formed by the two semi-circular grooves 102b, the outer diameter of the bulge is larger than the aperture of the round hole, generating a lateral thrust on the mold 102a, pushing the symmetrical mold 102a to move to both sides, driving the positioning block 103a to move outward. The movement of the positioning block 103a drives the slider 104a to move in the same direction. The movement of the slider 104a drives the I-shaped fixing plate 104c to move in the same direction. When the transmission rack 201a at the bottom of the I-shaped fixing plate 104c moves, it drives the meshing first transmission gear 201b to rotate. The rotation of the first transmission gear 201b drives the meshing second transmission gear 201e to rotate. The rotation of the second transmission gear 201e drives the rotating shaft 201f to rotate. The rotation of the rotating shaft 201f drives the baffle 202a to approach the side where the support column 202b is located. When the bulge passes through, the return spring 202c loses pressure and converts the pressure into elastic force to push the baffle 202a back to the initial position. Thus, it can be detected whether there is a bulge in the bundle tube and prevent the bundle tube with a bulge from being clamped off.

[0049] Another usage mode of this embodiment (refer to the appendix Figure 4 ) is used for assembling bundle tubes adapted to different apertures:

[0050] For detecting bundle tubes with different apertures, the molds 102a are symmetrically arranged and closely fit in the initial position. There are multiple semi-circular grooves 102b with different diameters, symmetrically arranged at the two ends of the mold 102a. The two parts of the symmetric molds 102a match each other so that the semi-circular grooves 102b can form a complete circle that matches the size of the bundle tube.

[0051] In summary, the beneficial effects of an adjustment mechanism can be achieved by adapting semi-circular grooves 102b of different sizes on the mold 102a to bundle tubes of different apertures, expanding the scope of application, so that bundle tubes of different apertures can all use this mechanism for detection. Through the cooperation of the manual knob 104g, the wire shaft 104d and the synchronous belt 104f, when the semi-circular groove 102b is at different heights, the slider 104a can be lifted to an appropriate height to cooperate with the bundle tube, and bundle tubes of different apertures do not need to replace the detection card board during detection.

[0052] Embodiment 3

[0053] Referring to Figure 6 , this is the third embodiment of the present utility model. This embodiment further provides a bulge detection device, which can alarm for bulges and record the positions where the bulges exist for later search.

[0054] Specifically, a bulge detection device includes the adjustment mechanism as in Embodiment 1 or Embodiment 2, and

[0055] a sensing unit 300, including a support component 301 arranged on one side of the bearing component 101, and an induction component 302 arranged on one side of the rotating component 202.

[0056] Furthermore, the support component 301 includes a second support plate 301a arranged on the top of the bearing component 101, a thimble 301b arranged inside the second support plate 301a, and a U-shaped groove 301c arranged on the top of the second support plate 301a.

[0057] Furthermore, the induction component 302 includes a switch sensor 302a, a limit disk 302b arranged outside the switch sensor 302a, and a second support plate 301a inserted into the limit disk 302b.

[0058] It should be noted that the switch sensor adopts the existing technology, which includes a detection head and a control terminal. The control terminal is provided with an alarm and a production interface. The initial position data of the baffle in the control terminal is recorded as 0. When a bulge appears in the bundle tube, the baffle approaches the switch sensor, and the data changes. The changed data is transmitted to the control terminal, so that the control terminal makes a record of the data and feeds back. The second support plate 301a is fixedly connected to the top of the base 101a. The thimble 301b is arranged through the inside of the second support plate 301a. The limit disk 302b is arranged outside the second support plate 301a. The switch sensor 302a is connected through the middle of the limit disk 302b.

[0059] During use, when the baffle 202a approaches the second support plate 301a, the proximity sensor 302a senses the shortening of the distance from the baffle 202a. At the same time, the distance detected by the proximity sensor 302a is converted into a pulse signal, and the pulse signal is fed back to the control terminal. The control terminal compares the detected data with the pre-stored data. When the detected data is less than 0, the control terminal controls the alarm to give an alarm. At the same time, the production interface set by the control terminal displays the distance between the baffle and the proximity sensor in real time, facilitating the staff to record the bulging situation. When the distance between the baffle 202a and the second support plate 301a is too close, the ejector pin 301b blocks the baffle 202a to prevent the baffle 202a from accidentally touching the proximity sensor 302a.

[0060] In summary, the beneficial effects of an induction device are as follows: through the cooperation of the baffle 202a and the proximity sensor 302a, the position where the bundle tube bulges can be recorded and an alarm feedback for the occurrence of the bulge can be given. When the distance between the baffle 202a and the proximity sensor 302a changes, a conductive pulse signal will be generated. When the pulse signal changes, this phenomenon will be fed back to the production interface and recorded. At this time, the system will display the number of meters where the bulge occurs, so as to quickly find the position of the bulge during later rewinding. By blocking the baffle 202a with the ejector pin 301b, it is possible to prevent the baffle 202a from accidentally touching the proximity sensor 302a.
