[0016] Figure 1 It is a schematic diagram of the placement of the cartridge body of the roll cartridge. Detailed Embodiments

[0017] The following clearly and completely describes the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0018] As Figure 1 , the embodiment of the present utility model provides a roll changing vehicle with convenient operation, including a vehicle body 1. A cartridge body 100 of a roll cartridge is provided on the vehicle body 1. A limiting wheel is rotatably installed on the vehicle body 1. The axis of the limiting wheel is parallel to the axis of the roll. A limiting groove is correspondingly provided on the cartridge body 100 of the roll cartridge. The limiting wheel is engaged into the limiting groove, so that the cartridge body 100 of the roll cartridge is detachably installed on the vehicle body 1.

[0019] By fitting the limiting wheel into the limiting groove, the restraint of the roller box body 100 can be realized. This restraint includes lateral restraint (the lateral direction is the horizontal direction perpendicular to the axis of the limiting wheel) and longitudinal restraint (the longitudinal direction is the horizontal direction parallel to the axis of the limiting wheel). For example, the diameter of the limiting wheel is the same as or close to the groove width of the limiting groove, the axial length of the limiting wheel is the same as or close to the length of the limiting groove, and preferably, the diameter of the limiting wheel is the same as or close to the groove depth of the limiting groove. The above-mentioned roller box body 100 can be the box body of an old roller box or the box body of a new roller box.

[0020] Preferably, there are multiple limiting wheels, which can ensure the restraint effect on the roller box body 100; preferably, the number of limiting grooves is the same as the number of limiting wheels and they are arranged in one-to-one correspondence.

[0021] The above-mentioned limiting wheel is rotatably installed on the vehicle body 1. In addition to being able to restrain and position the roller box body 100, when the roller box body 100 is disassembled and assembled, the limiting wheel can also be used as the moving track of the roller box body 100, which can ensure the smoothness of the movement of the roller box body 100.

[0022] Preferably, as Figure 1 , the limiting wheels are arranged in layers, including a first limiting layer and a second limiting layer. The first limiting layer is located below the second limiting layer, and the first limiting layer and the second limiting layer each include at least one limiting wheel; corresponding to the settings of the first limiting layer and the second limiting layer, the limiting grooves on the roller box body 100 are designed in a matching manner to ensure that each limiting wheel can cooperate with the corresponding limiting groove. For example, a bottom limiting groove 101 is provided at the bottom of the roller box body 100 to cooperate with the first limiting wheel 11 in the first limiting layer; an upper limiting groove 102 is provided on the roller box body 100, and the upper limiting groove 102 is located above the bottom limiting groove 101 to cooperate with the second limiting wheel 12 in the second limiting layer.

[0023] Furthermore, as Figure 1 , a horizontal channel 103 for the second limiting wheel 12 to pass through is opened on the roller box body 100, and the horizontal channel 103 is communicated with the upper limiting groove 102, so that the second limiting wheel 12 can enter the upper limiting groove 102 via the horizontal channel 103; at the same time, a guiding cooperation relationship can be formed between the second limiting wheel 12 and the horizontal channel 103, thereby significantly improving the translation stability and reliability of the roller box body 100.

[0024] Among them, preferably, the upper limiting groove 102 is closer to the roller inlet and outlet of the roller box body 100 than the bottom limiting groove 101, and the horizontal channel 103 penetrates through the corresponding lateral end of the roller box body 100, so as to better guide the translation movement of the roller box body 100.

[0025] The above-mentioned vehicle body 1 is preferably equipped with traveling wheels, and more preferably equipped with a traveling drive mechanism, so that the vehicle body 1 can move by itself.

[0026] In one embodiment, an old roller cartridge and a new roller cartridge are provided on the vehicle body 1, and the old roller cartridge and / or the new roller cartridge adopt the roller cartridge body 100.

[0027] The old roller cartridge and the new roller cartridge are preferably provided with an open top, which is convenient for the insertion and removal of the rollers.

[0028] When the old roller cartridge and / or the new roller cartridge are detachably arranged on the vehicle body 1, the production convenience can be improved. For example, several new rollers can be placed in the new roller cartridge and then lifted onto the vehicle body 1 together. After the old roller cartridge collects several old rollers, they can be lifted off the vehicle body 1 together. This can prevent the hoisting of the rollers on the vehicle body 1, and the safety and convenience are higher.

[0029] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
