[0041] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0042] Example 1:

[0043] This embodiment provides a carton cardboard slotting machine, comprising:

[0044] The machine base 1 is provided with a loading platform 2;

[0045] The slotting mechanism 3 is mounted on the machine base 1 and includes a first drive shaft 30 and a second drive shaft 31 arranged in parallel, a groove wheel 32 sleeved on the first drive shaft 30, a receiving wheel 33 sleeved on the second drive shaft 31, a groove cutter 34 mounted on the groove wheel 32, and a drive assembly for driving the first drive shaft 30 and the second drive shaft 31 to rotate;

[0046] A feeding mechanism 4 is installed on the feeding platform 2 and is used to feed the slotting mechanism 3;

[0047] A gap is formed between the groove wheel 32 and the receiving wheel 33 for the cardboard to pass through, and the receiving wheel 33 is equipped with a stamping assembly 5;

[0048] At the same time, the drive assembly can use a drive motor, and its output end is linked with the first drive shaft 30 and the second drive shaft 31. Its specific structure and drive transmission method are existing mature technologies and will not be described here.

[0049] In addition, the feeding mechanism 4 includes a storage frame for placing carton paperboard, a push plate for pushing the carton paperboard into the slotting mechanism 3, and a driving member for driving the push plate to move back and forth. The driving member can be a cylinder or a screw drive assembly that can realize the reciprocating movement of the push plate. Its specific structure is an existing mature technology and will not be described here.

[0050] If necessary, the rotation direction of the control drive assembly and the feeding speed of the feeding mechanism 4 can be adjusted so that the slotting knife 34 can just slot both sides of the carton cardboard and ensure the efficiency of continuous slotting. This control method and the unit used for control are both available in existing slotting machines and are existing mature technologies, so they will not be repeated here.

[0051] It can be seen from this embodiment that by arranging the stamping component 5 on the receiving wheel 33, the carton is stamped, which facilitates the subsequent bending and forming of the carton, not only improving work efficiency, but also avoiding the additional drive shaft and power source, simplifying the structure, and effectively reducing manufacturing costs.

[0052] Example 2:

[0053] This embodiment provides a carton cardboard slotting machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0054] The receiving wheel 33 has an annular groove 330 formed on its circumference, and the annular groove 330 is arranged axially corresponding to the groove cutter 34;

[0055] The stamping assembly 5 includes an arc-shaped convex strip 50 disposed in the annular groove 330 for stamping the cardboard, and the arc-shaped convex strip 50 protrudes from the surface of the receiving wheel 33;

[0056] There are two arc-shaped ridges 50 and two groove cutters 34, and a knife-avoiding groove 51 is formed between the two arc-shaped ridges 50. The knife-avoiding groove 51 is arranged corresponding to the groove cutter 34 along the circumferential direction.

[0057] At the same time, bolts can be used to fasten the arc-shaped ridge 50 to the inner wall of the annular groove 330 in the receiving wheel 33, and the length of the knife-avoiding groove 51 along the circumference must be greater than the length of the groove knife 34 along the circumference to ensure that the groove knife 34 does not touch the arc-shaped ridge 50 when it turns into the annular groove 330, thereby avoiding damage to the groove knife 34 and extending its service life.

[0058] It can be seen from this embodiment that by adopting the arc-shaped ridge 50, the structure is simple, and by adjusting its position so that it does not interfere with the groove cutter 34, the stamping process can be completed during the process of grooving both sides of the carton, and the work efficiency is high.

[0059] Example 3:

[0060] This embodiment provides a carton cardboard slotting machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including:

[0061] The limiting assembly 6 is installed on the first drive shaft 30 and the second drive shaft 31 and is used for limiting the connection between the groove wheel 32 and the first drive shaft 30 and between the receiving wheel 33 and the second drive shaft 31.

[0062] It can be seen from this embodiment that the groove wheel 32 and the receiving wheel 33 are limitedly installed by the limiting component 6, so as to avoid damage caused by the mutual influence between the groove knife 34 and the arc-shaped convex strip 50 due to misalignment or deviation, thereby extending the service life and ensuring that the groover can groove and stamp the carton cardboard.

[0063] Example 4:

[0064] This embodiment provides a carton cardboard slotting machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the limiting component 6 includes:

[0065] The sleeve 60 is provided in plurality and is respectively sleeved on the first drive shaft 30 and the second drive shaft 31, and one end of the sleeve is provided with a flange end for connecting with the groove wheel 32 and the receiving wheel 33;

[0066] The fastening bolt 61 is vertically inserted through the sleeve 60 and is threadedly connected to the sleeve 60 and abuts against the first drive shaft 30 and the second drive shaft 31 respectively;

[0067] The first drive shaft 30 and the second drive shaft 31 are provided with grooves 62 corresponding to the fastening bolts 61;

[0068] At the same time, the number of sleeves 60 is the same as the sum of the number of groove wheels 32 and the receiving wheels 33, and the number of groove wheels 32 and the receiving wheels 33 is the same, and one cardboard needs to open eight grooves twice, so the number of groove wheels 32 and the receiving wheels 33 are four, so the number of sleeves 60 is eight, and each sleeve 60 is correspondingly provided with three fastening bolts 61, and the number of notches 62 is the same as the number of fastening bolts 61, which is also three;

[0069] Furthermore, two adjacent notches 62 are not connected, that is, the surfaces of the first drive shaft 30 and the second drive shaft 31 fit with the inner wall of the sleeve 60, ensuring the coaxiality between the first drive shaft 30 and the groove wheel 32 and the second drive wheel and the receiving wheel 33.

[0070] It can be seen from the present embodiment that the flange end is adopted to facilitate the connection strength between the sleeve 60 and the groove wheel 32 and the sleeve 60 and the receiving wheel 33, and the coaxiality is high, thereby ensuring the accuracy of grooving the carton board. The axial and radial limitations of the sleeve 60 on the first drive shaft 30 and the second drive shaft 31 by tightening the bolts 61 improve the installation stability of the groove wheel 32 and the receiving wheel 33, further ensuring the accuracy of grooving the carton board, and convenient disassembly, which facilitates the axial adjustment of the position of the groove wheel 32 and the receiving wheel 33, thereby improving convenience.

[0073] The sleeve 60 is provided with an extension portion 63 along the radial direction at the fastening bolt 61;

[0074] The extension portion 63 and the sleeve 60 are welded.

[0075] It can be seen from this embodiment that by radially arranging an extension portion 63 on the sleeve 60 at the fastening bolt 61, the connection strength between the fastening bolt 61 and the sleeve 60 is effectively improved, thereby improving the installation stability of the sleeve 60 on the first drive shaft 30 and the second drive shaft 31.

[0076] Example 6:

[0077] This embodiment provides a carton cardboard slotting machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0078] A chamber is formed between the inner wall of the sleeve 60 and the notch 62, and an abutment block 64 is provided in the chamber;

[0079] The two sides of the abutment block 64 abut against the fastening bolt 61 and the notch 62 respectively;

[0080] At the same time, gaps are left between the abutment block 64 and the inner wall of the sleeve 60 and the surface of the slot 62, so as to facilitate the insertion of the abutment block 64 into the cavity.

[0081] It can be seen from the present embodiment that by installing the abutment block 64 in the chamber formed by the opening of the slot 62, not only the structural strength is improved, but also the wear on the surface of the slot 62 caused by the tightening of the fastening bolt 61 can be avoided, thereby ensuring the flatness of the surface of the slot 62 and extending the service life. If replacement is required, only the fastening bolt 61 and the abutment block 64 need to be replaced, and there is no need to replace the first drive shaft 30 and the second drive shaft 31, thereby reducing the cost of maintenance and replacement.

[0082] Example 7:

[0084] The surface of the notch 62 is provided with a scale 65, and the abutment block 64 is provided with a sliding groove 66 adapted to the scale 65;

[0085] The scale 65 is made of metal and is fastened to the first drive shaft 30 and the second drive shaft 31 by bolts. Moreover, when the abutment block 64 abuts against the surface of the notch 62 , a gap remains between the slide groove 66 and the surface of the scale 65 .

[0086] It can be seen from this embodiment that by providing the scale 65, it is convenient to accurately adjust the positions of the groove wheel 32 and the receiving wheel 33, and it is convenient to align the positions of the groove wheel 32 and the receiving wheel 33, thereby ensuring the grooving effect, avoiding damage to the groove cutter 34 due to deviation, and extending the service life;

[0087] At the same time, the provision of the sliding groove 66 on the abutting block 64 improves the installation convenience of the abutting block 64 and avoids damage to the scale 65.

[0088] Example 8:

[0089] This embodiment provides a carton cardboard slotting machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0090] The first drive shaft 30 and the second drive shaft 31 are linked by a synchronous wheel and a synchronous belt;

[0091] Among them, the specific structure and specific connection method of the synchronous wheel and the synchronous belt are existing mature technologies and will not be repeated here.

[0092] It can be seen from this embodiment that by linking the first drive shaft 30 and the second drive shaft 31 with a synchronous belt, the installation accuracy of the groove wheel 32 and the receiving wheel 33 is further guaranteed, and the groove knife 34 and the arc-shaped ridge 50 will not affect each other, thereby ensuring the use of the grooving machine.
