[0002] In the production process of waterproof coiled material, it is required to vertically align the center of the formed waterproof coiled material, and then insert the roll core into the waterproof coiled material at a proper force and angle, so as to complete the plug-in process of the waterproof coiled material. In the existing roll core plug-in mechanism, the stroke of the positioning component for positioning the roll core is relatively fixed, so it cannot effectively position the roll core of different lengths, which may lead to plug-in failure and damage to the roll core. SUMMARY

[0003] In view of the above at least one defect or deficiency of the prior art, the present application provides a waterproof coiled material roll core plug-in mechanism and a waterproof coiled material production system, which can be compatible with positioning operations of roll cores of different lengths, realize accurate plug-in of roll cores of different lengths, and effectively avoid damage to the roll core.

[0004] To achieve the above-mentioned purpose, the first aspect of the present application provides a waterproof coiled material roll core plug-in mechanism, comprising:

[0005] a plug-in station;

[0006] a positioning assembly comprising a transmission rod and a push rod arranged at the end of the transmission rod and elastically stretchable along the axial direction thereof; and

[0007] a positioning driving device for driving the transmission rod to move so that the push rod is coaxially pressed to the end of the roll core placed in the plug-in station.

[0008] In some embodiments, the positioning assembly comprises a guide sleeve fixedly arranged at the end of the transmission rod, and the push rod is elastically stretchable through the guide sleeve.

[0009] In some embodiments, the sleeve open end of the guide sleeve is formed with a sleeve ring plate portion arranged radially outward, the push end of the push rod is formed with a push ring plate portion arranged radially outward, and the positioning assembly further comprises an elastic member arranged between the sleeve ring plate portion and the push ring plate portion.

[0010] In some embodiments, the elastic member is formed as a spring sleeved outside the push rod.

[0011] In some embodiments, the pushing rod is formed with a limiting end opposite to the pushing end, the limiting end is arranged outside the guide sleeve and is provided with a limiting part extending radially, and the limiting part is capable of limiting abutting with the end of the guide sleeve.

[0012] In some embodiments, the limiting end is formed with a threaded structure extending along the axial direction, and the limiting part is formed as a nut matched with the threaded structure.

[0013] In some embodiments, the positioning driving device is formed as a rotating driving device for driving the transmission rod to swing.

[0014] In some embodiments, the waterproof roll core inserting mechanism further comprises a linear driving device for driving the positioning driving device to move along the axial direction of the roll core arranged in the inserting station.

The key is that when the moving stroke of the transmission rod is relatively fixed, in order to adapt to the positioning of roll cores with different lengths, the pushing rod can be elastically stretched and contracted along the axial direction thereof. Therefore, when a relatively short roll core is contacted, the pushing rod can be in contact with the end of the roll core, and further when a relatively long roll core is contacted, the pushing rod can be adaptively contracted along the axial direction to avoid damaging the roll core, and the pushing rod can be coaxially pressed to the roll core, which is helpful for the accurate insertion of the roll core.

[0029] A roll core DETAILED DESCRIPTION

[0030] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0031] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0032] As Figure 1 and Figure 2 shown, the first exemplary embodiment of the present application provides a waterproof roll core inserting mechanism, which comprises an inserting station, a positioning assembly and a positioning driving device 6, wherein the positioning assembly comprises a transmission rod 1 and a push rod 2, the push rod 2 is arranged at the end of the transmission rod 1 and can elastically stretch and contract along its own axial direction, and the positioning driving device 6 is used to drive the transmission rod 1 to move so that the push rod 2 coaxially press-bonds to the end of the roll core A placed in the inserting station.

[0033] In the waterproof roll core inserting mechanism of the present application, the push rod 2 which can elastically stretch and contract along its own axial direction is specially arranged, in the case that the stroke of the positioning driving device 6 driving the transmission rod 1 to move is relatively fixed, the push rod 2 can be elastically stretched and contracted along its own axial direction to adapt to the roll core A with different diameters, so that the push rod 2 can be coaxially press-bonded to the end of the roll core A with different diameters. Figure 2As shown, the push rod 2 is in a self-adapting elastic compression mode, and can be relatively contracted when abutting against the end of the roll core A, thereby playing a buffering effect and avoiding crushing the end of the roll core A. Meanwhile, the contracted push rod 2 can keep a coaxial state with the roll core A, thereby ensuring a high precision in the subsequent operation of moving the roll core A for insertion. Especially for the working condition of positioning different lengths of roll cores A in sequence, in the case of ensuring that the push rod 2 can abut against the shortest roll core A within a limited stroke, if a longer roll core A is to be positioned, it is not necessary to switch the shorter push rod 2 to match the longer roll core A, but only needs to drive the push rod 2 to move according to the same stroke, thereby improving the compatibility of the mechanism and saving the trouble of frequently switching the push rod 2 or adjusting the stroke of the push rod 2.

[0034] Referring to Figure 2 In the embodiment, in order to improve the stability of the push rod 2, the positioning assembly includes a guide sleeve 3 fixedly arranged at the end of the transmission rod 1, and the push rod 2 is elastically inserted into the guide sleeve 3. Under the limiting of the guide sleeve 3, the push rod 2 will not swing during the extension and contraction process, and keeps linear extension and contraction, thereby improving the positioning precision of the roll core A.

[0035] It should be noted that the structure of the guide sleeve 3 is not limited in the application, for example, the guide sleeve 3 can be open at both ends, or can be open at one end and closed at the other end, as long as the push rod 2 can extend out of the guide sleeve 3. In addition, there are various ways to realize the elastic extension and contraction of the push rod 2 relative to the guide sleeve 3, for example, in the embodiment where the guide sleeve 3 is closed at one end and open at the other end, an elastic member such as a spring can be arranged between the push rod 2 inserted into the guide sleeve 3 and the closed end, so that the push rod 2 can extend and contract in the guide sleeve 3. Alternatively, the push rod 2 is made of an elastic material such as rubber, and the extension and contraction is realized by the elastic deformation of the push rod 2 itself. Alternatively, as shown in the embodiment, the sleeve open end of the guide sleeve 3 is formed with a sleeve ring plate part 301 extending radially, the push end of the push rod 2 extends out of the sleeve open end and is formed with a push ring plate part 201 extending radially, and the positioning assembly further includes an elastic member arranged between the sleeve ring plate part 301 and the push ring plate part 201. Figure 2 Further, the elastic member can be formed as a spring 4 sleeved outside the push rod 2. In the embodiment, when the transmission rod 1 drives the push rod 2 to compress the end of the roll core A, the spring 4 is compressed between the sleeve ring plate part 301 and the push ring plate part 201, so that the push rod 2 moves into the guide sleeve 3. At this time, the guide sleeve 3 can continue to approach the end of the roll core A until the positioning driving device 6 drives the transmission rod 1 to move to a preset stroke.

[0036] In an alternative or preferred embodiment, the other end of the pushing rod 2 is formed as a limiting end relative to the pushing end in the axial direction, the limiting end extends out of the guide sleeve 3 and is provided with a limiting portion extending in the radial direction, the limiting portion can form a limiting abutment with the end of the guide sleeve 3, thereby preventing the pushing rod 2 from moving out of the guide sleeve 3.

[0037] Further, the peripheral wall of the limiting end is formed with a threaded structure extending in the axial direction, and the limiting portion is formed as a nut 5 connected with the threaded structure. On the one hand, the nut 5 can form a limiting abutment with the end of the guide sleeve 3, preventing the pushing rod 2 from moving out of the guide sleeve 3, and on the other hand, the threaded connection between the nut 5 and the limiting end can facilitate the adjustment of the axial position of the nut 5 on the pushing rod 2, and the adjustment of the axial position of the nut 5 on the pushing rod 2 can adjust the extension length of the pushing end of the pushing rod 2, which is helpful for the abutting positioning of the winding core A of different lengths.

[0038] In an alternative or preferred embodiment, the positioning driving device 6 is formed as a rotary driving device 601 for driving the transmission rod 1 to swing, such as a pneumatic motor, a hydraulic motor, a rotary motor, etc., which is not limited in the present application. Figure 2 In the embodiment shown, one end of the transmission rod 1 is sleeved on the output shaft of the rotary driving device 601, and the other end is fixedly connected to the pushing rod 2, wherein the pushing rod 2 and the transmission rod 1 can be arranged perpendicular to each other, and the rotary driving device 601 can drive the transmission rod 1 to rotate back and forth by 90 degrees, so that the pushing rod 2 moves between the avoiding position and the positioning position. In the avoiding position, the transmission rod 1 is in a horizontal state, and the pushing rod 2 is in a vertical state; in the positioning position, the transmission rod 1 is in a vertical state, and the pushing rod 2 is in a horizontal state. In other embodiments, the rotary driving device 601 can also drive the transmission rod 1 to rotate by a certain angle, as long as the pushing rod 2 can abut against the winding core A placed in the insertion station.

[0039] In order to quickly perform the insertion operation after positioning is completed, the waterproof roll core insertion mechanism further comprises a linear driving device 7 for driving the positioning driving device 6 to move along the axial direction of the winding core A placed in the insertion station. Thus, when the positioning driving device 6 drives the pushing rod 2 to abut against the winding core A, the linear driving device 7 can be used to drive the positioning driving device 6 as a whole to move towards the winding core A, so that the pushing rod 2 pushes the winding core A in the axial direction until the winding core A is completely inserted into the center of the waterproof roll, thereby completing the insertion operation of the winding core A.

[0040] In Figure 1In the shown embodiment, the linear driving device 7 comprises a slide rail 701 arranged along the axial direction of the winding core A and a slide block 702 in sliding cooperation with the slide rail 701, and the positioning driving device 6 is fixedly connected to the slide block 702, wherein the slide block 702 can be driven by a linear motor, a linear cylinder or a linear oil cylinder to slide on the slide rail 701, so as to drive the positioning driving device 6 to move along the slide rail 701 as a whole.
