Description

Technical Field

[0001] The utility model relates to the field of packaging equipment, in particular to the field of hard box packaging machines, and in particular to a positioning device for a creasing roller of a hard box packaging machine. Background Art

[0002] A rigid box packaging machine is a device used for packaging rigid boxes. When packaging rigid boxes, the rigid box packaging machine needs to use a creasing roller to press the box material on the conveying line of the box material of the rigid box packaging machine to form a contour line on the box, so as to facilitate the subsequent operation to fold the box according to the contour line.

[0003] When the creasing roller is currently installed on the conveyor line of the hard box packaging machine, it is supported by a fixed-structure support. Because the support is fixed in specifications, the position of the creasing roller cannot be adjusted, making its use structure single. When the creasing roller has an operating deviation, the operating posture can only be adjusted by replacing the support or the creasing roller. This has certain limitations and the operation and maintenance costs are high.

[0004] When the creasing roller is assembled with the help of a common lifting support, due to the large movable margin of the lifting support, when the creasing roller is adjusted to the required position and when the creasing roller is maintained later, it is usually necessary to use measuring tools such as a ruler to determine its support position and adjust it step by step, which complicates the operation and reduces the efficiency of use. Utility Model Content

[0005] In order to solve the technical problems of complicated and cumbersome installation and positioning operation of the creasing roller and low efficiency, the utility model provides a positioning device for the creasing roller of a hard box packaging machine. By lifting and lowering the bearing seat along the bracket, the supporting position of the creasing roller is adjusted, and the probe on the support rod performs abutment detection on the positions of both sides of the creasing roller, so that the positioning and installation operation is simple and labor-saving, and the operating efficiency is improved.

[0006] The technical solution adopted by the utility model is: to provide a positioning device for the creasing roller of a hard box packaging machine, comprising a support rod, on which a retractable probe is movably arranged, and the retractable probe is rotatably installed with the support rod; "n"-shaped brackets are fixedly installed at both ends of the support rod, and bearing seats are lifted and lowered in the brackets, the bearing seats are locked and installed with the brackets by means of locking pieces, and support bearings are installed in the bearing seats; an creasing roller is arranged between the brackets, and both ends of the creasing roller are sleeved with the support bearings; both ends of the creasing roller are fixedly sleeved with detection rings, the detection rings are located between the support bearings and the end faces of the creasing roller, and are abutted and matched with the retractable probe.

[0007] After the support bearings and bearing seats at both ends of the creasing roller are assembled, the bearing seats are installed in the bracket, and the bracket is installed on the conveying line of the hard box packaging machine. Then, by adjusting the position of the bearing seat on the bracket and locking it with the help of a locking piece, the creasing roller is positioned and supported. The retractable probe on the support rod is adjusted according to the use requirements of the roller pressing shaft, and is slid to one end of the support rod. After abutting with the detection ring at one end of the creasing roller, the assembly position of the creasing roller is determined, and the probe is slid to the other end of the support rod, abutting with the detection ring at the other end of the creasing roller, and detecting its position, so that the creasing roller is assembled horizontally to ensure that the creasing is complete and reliable. By rotating the creasing roller, the ring wall of the detection ring is fully abutted with the probe. By observing whether the probe skips frames, the accuracy of the installation of the creasing roller is judged. It is flexible and easy to use.

[0008] To further optimize the technical solution, polygonal docking blocks are detachably mounted on both ends of the support rod, the docking blocks abut against the outer wall of the bracket, and the docking blocks are fixedly connected to the bracket by means of bolts.

[0009] The support rod is fixedly installed with the bracket through the docking blocks installed at both ends. The docking blocks increase the installation position, making the installation of the support rod and the bracket simple and labor-saving.

[0010] To further optimize the technical solution, the docking block includes a polygonal docking piece, one end of which abuts against the bracket and is connected to the bracket by means of bolts, and the other end is fixedly installed with a sleeve, the sleeve is plugged into the support rod, and the sleeve is fixed to the support rod by means of a pin.

[0011] The docking block is plugged into the support rod through the sleeve, and the pin passes through the sleeve and the support rod to pin them and fix them to avoid separation of the sleeve and the support rod. The assembly is simple. After the docking piece at the other end of the sleeve abuts against the outer wall of the bracket, it is connected to the bracket with the help of bolts. The docking piece increases the contact area with the bracket, making the assembly stable and firm.

[0012] To further optimize the technical solution, the outer wall of the bracket is provided with a docking groove, the docking piece corresponds to the shape of the docking groove and is slidably inserted into the docking groove, and a threaded groove is provided in the docking groove; the bolts are circumferentially distributed on the docking piece, correspond to the number and position of the threaded grooves, and are threadedly connected to the threaded grooves.

[0013] The docking piece is plugged into the docking groove on the bracket. Its polygonal structure makes the plugging stable and facilitates the rapid docking of the bolt and the thread groove. After the bolt is threadedly connected with the thread groove, the docking piece is locked in the docking groove, which is easy to assemble.

The operation is simple and flexible.

[0016] To further optimize the technical solution, the telescopic sleeve includes at least two sleeves sleeved with each other, and the sleeves are threadedly connected with each other.

[0017] The sleeves that are sleeved on each other are connected by threads, and their expansion and contraction are adjusted by the thread engagement. The thread engagement of the sleeve can prevent the sleeve from expanding and contracting at will, making the detection more accurate.

[0018] To further optimize the technical solution, vertical slide grooves are provided on both the front and rear sides of the bearing seat, the bearing seat is slidably connected to the bracket through the slide grooves, and the locking member corresponds to the position of the slide grooves; the bearing seat is lifted and installed with the help of a driving member and the bracket.

[0019] The sliding grooves at the front and rear ends of the bearing seat and the sliding installation of the bracket limit the movement of the bearing seat so that it can only be lifted and lowered along the bracket, making it easy and labor-saving to drive the driving part.

The bracket restricts the running state of the bearing seat to prevent the bearing seat from rotating synchronously with the screw rod, making the lifting drive smoother. The engagement of the screw rod and the nut has a self-locking effect, making the operation more labor-saving.

[0022] To further optimize the technical solution, the locking member includes a tightening bolt threadedly connected to the bearing seat, the tightening bolt passes through the slide groove and abuts against the bracket.

[0023] After the tightening bolt passes through the slide slot and abuts against the bracket, the friction between the tightening bolt and the bracket is increased, thereby locking and fixing the position of the bearing seat. The structure is simple, the operation is convenient, and the use is stable and reliable.

[0024] The beneficial effects of the utility model are:

[0025] 1. When the screw is rotated to engage with the nut to drive the bearing seat to rise and fall along the bracket, the bearing seat is installed by sliding with the bracket through the slide groove to limit its movement state and avoid rotating with the screw, so that the lifting drive is smooth and simple. The screw and the nut are engaged and self-locked to support the bearing seat. At the same time, the tightening bolts increase the friction between the bearing seat and the bracket, and coordinately fix the bearing seat, so that the position of the bearing seat is fixed firmly and reliably.

[0026] 2. When using the probe to adjust the support position of the bearing seat for the indentation roller, the connecting ring slides to one side along the support rod, the sleeve adjusts the extension amount through thread engagement, and after abutting with the detection ring on the indentation roller, the installation position is determined, and then the probe is slid to the other side of the support rod and abutted with the detection ring on the other side of the indentation roller, so that the heights of both sides of the indentation roller are the same, the installation is accurate, and the thread engagement of the sleeve avoids changes in the probe length and improves the detection accuracy;

[0027] 3. When the support rod is assembled with the bracket through the docking block, the docking block is plugged into the support rod through the sleeve and fixed with the help of pins. The docking piece on the sleeve is plugged into the docking groove on the bracket. The polygonal structure of the docking piece and the docking groove makes the plug-in position firm and stable, and makes the thread groove correspond to the bolt, so that the connection and locking are convenient and labor-saving.
