[0034] The utility model provides a quick installation fixture for a paper core tube, which is used in the positioning and installation process of multiple core tubes. The utility model does not limit the type of core tubes, but the structure of the quick installation fixture for a paper core tube is particularly suitable for the demand for quick installation of multiple paper core tubes.

[0035] In general, the quick installation fixture of the paper core tube proposed in the utility model mainly includes a No. 1 fixture body 1, a No. 2 fixture body 2, a No. 3 fixture body 3, an external connecting pipe 4, and an adjusting block 5. Figure 1 , which shows the arrangement relationship of the No. 1 clamp body 1, the No. 2 clamp body 2, the No. 3 clamp body 3, the external connecting pipe 4, and the adjusting block 5.

[0036] In order to achieve the purpose of inserting multiple paper core tubes into the core shaft at one time, the problem that the paper core in the background technology is a product with a small circular ring structure, when a small shaft needs to be inserted into multiple paper cores, the circular paper cores are conventionally inserted into the core shaft one by one manually, but the consistency and accuracy of the gap cannot be guaranteed, resulting in deviation or jamming of the paper core during the insertion process; and manual operation is easily affected by various factors, such as the worker's proficiency, fatigue level and operating environment, etc. These factors may lead to unstable operation, thereby affecting the quality and efficiency of insertion; in addition, the processing difficulty of long tube structural parts is large, the finished product requirements are high, and the production cost will also be increased. For this reason, in the technical solution provided in this embodiment, three segmented plastic parts, namely, the first clamp body 1, the second clamp body 2 and the third clamp body 3, are spliced ​​to form a longer structural part, and the annular groove 6 for installing the core tube is matched inside to achieve the installation and fixation of multiple core tubes at equal intervals. In addition, an adjustment block is used at the end of the first clamp body 1 to adjust the overall length of the installation clamp to achieve the effect of adapting to the positioning of the equipment, and the installation is simple, fast and convenient.

[0037] Specifically, Figure 1 As shown, the quick installation clamp of the paper core tube comprises a clamp body No. 1, a clamp body No. 2, and a clamp body No. 3, which are arranged in sequence along the axial head and tail. The clamp body No. 1, the clamp body No. 2, and the clamp body No. 3 are all matched in a semicircle to form an annular structure. When the core tube is not installed, they are two separate semicircular structures. When a core tube is installed in the middle, they are covered to form a circular ring structure.

[0038] Then, if Figure 5 As shown, the inner walls of the No. 1 clamp body 1, the No. 2 clamp body 2 and the No. 3 clamp body 3 are all provided with annular grooves 6 for installing core barrels, and a plurality of annular grooves 6 are arranged at equal intervals corresponding to the number of the installing core barrels.

[0039] Considering that the quick installation fixture of the paper core tube can be adaptively changed according to the number of core tubes, on the one hand, the number of the second fixture body 2 can be increased or decreased according to the number of products, and on the other hand, Figure 2 As shown, the end of the No. 1 clamp body 1 close to the No. 2 clamp body 2 is provided with a concave annular groove 6, correspondingly, as shown in FIG. Figure 3 As shown, the inner diameter of the end of the second clamp body 2 close to the first clamp body 1 is consistent with the inner diameter of the core tube, and then the end of the second clamp body 2 close to the third clamp body 3 is provided with a concave annular groove 6, correspondingly, as shown Figure 4 As shown, the inner diameter of the end of the No. 3 clamp body 3 close to the No. 2 clamp body 2 is consistent with the inner diameter of the core tube, and the inner diameter of the other end of the No. 3 clamp body 3 is consistent with the inner diameter of the core tube. Through the above structure, the number of No. 2 clamp bodies 2 can be increased or decreased without affecting the stable installation structure of the overall quick installation clamp.

[0040] On this basis, in order to ensure that the connection between the clamp body No. 1, the clamp body No. 2 and the clamp body No. 3 can be stably and not loose, an external connecting tube 4 is sleeved on the outside of the connection between the clamp body No. 1 and the clamp body No. 2, and the clamp body No. 2 and the clamp body No. 3; in the present embodiment, a No. 1 bolt hole 8 is provided between adjacent annular grooves 6 at the connection between the clamp body No. 1, the clamp body No. 2 and the clamp body No. 3, and a No. 2 bolt hole 9 is also provided on the external connecting tube 4 accordingly. When in use, the bolts are passed through the No. 1 bolt hole 8 and the No. 2 bolt hole 9 to achieve a fastened installation.

[0041] As mentioned above, an adjustment block 5 is also provided in this embodiment for adjusting the connection length between the installation fixture and the equipment to meet the requirements of different sizes. The adjustment block 5 is installed on the inner wall of the end of the No. 1 clamp body 1 away from the No. 2 clamp body 2, and a recessed installation groove 12 is correspondingly provided on the inner side of the end of the No. 1 clamp body 1 away from the No. 2 clamp body 2 to install the adjustment block 5; when adjusting, since a plurality of adjustment holes 10 are provided on the adjustment block 5 at equal intervals along the circumferential direction, a positioning hole 7 is provided on the No. 1 clamp body 1 corresponding to the installation position of the adjustment block 5, it is only necessary to change the position of the bolt passing through the adjustment hole 10 and the positioning hole 7 during adjustment; preferably, in order not to affect the passage of the middle long axis, the inner diameter of the adjustment block 5 is larger than the minimum inner diameter of the No. 2 clamp body 2.

[0042] like Figure 1 As shown, handles 11 are installed on the outer circumference of the No. 1 clamp body 1, the No. 2 clamp body 2 and the No. 3 clamp body 3, and a pair of handles 11 are symmetrically arranged on the same horizontal plane, which can facilitate manual operation and improve installation efficiency.

[0043] 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.
