DETAILED DESCRIPTION

[0018] The utility model will be further described below in conjunction with the accompanying drawings.

[0019] like Figure 1 As shown, a material rack structure of a rotary laminating and lifting machine includes a material box 1, a hot air chamber 2 is provided at the bottom of the material box 1, a ventilation plate 3 is provided on the hot air chamber 2, the material box 1 includes a material roll placement area 4 and a heating area 5 located at the rear side of the material roll placement area 4, the material roll placement area 4 includes one or more material trays 6 arranged above the ventilation plate 3, each material tray 6 is provided with a material roll, and a plurality of ventilation holes 8 are provided on the ventilation plate 3 located below the material roll, the heating area 5 includes a plurality of fan heaters 9, and the air outlets of the plurality of fan heaters 9 are connected to the hot air chamber 2, and a lifting channel 10 is provided on the top of the material box 1.

[0020] The material rack structure of a rotary laminating and lifting machine of the present invention is provided with one or more material trays 6 in the material box 1, and each material tray 6 is provided with a material roll. If several material trays 6 are provided, the purpose is to quickly switch to the material rolls on other spare material trays 6 after the material rolls on one of the material trays 6 are used up, so as to speed up the loading speed of the material rolls. A ventilation plate 3 with multiple through holes is provided at the bottom of the material box 1, and the ventilation plate 3 is connected to the hot air chamber 2. Several fan heaters 9 can send the heat seal to the hot air chamber 2 and blow it to the material roll through the ventilation holes 8, so that the temperature of the material roll is increased, the viscosity of the adhesive on the lifting belt is increased, and the adhesive is softened at the same time, so as to facilitate the smooth release of the material roll. Among them, one or more lifting channels 10 are provided at the top of the material box 1 to facilitate material discharge.

[0021] Preferably, the material tray 6 includes a bracket 12, a transmission assembly arranged on the bracket 12, and a support assembly connected to the transmission assembly, the transmission assembly includes a transmission shaft 13, a first bearing seat 14 and a second bearing seat 15, the transmission shaft 13 passes through the first bearing seat 14 and the second bearing seat 15, the first bearing seat 14 and the second bearing seat 15 are respectively fixedly arranged on the bracket 12, the tail of the transmission shaft 13 abuts against the bracket 12 through an abutment block 16, and the head of the transmission shaft 13 is fixedly connected to the bracket 12 through a cover plate and a screw 17; the support assembly includes three groups of material tray support units arranged at equal intervals along the circumference of the bracket 12, each material tray support unit includes a rib plate 18 welded to both ends of the bracket 12, the rib plate 18 is connected to two support sheets 21 that can contact the core of the material roll barrel through a rotating shaft 19 and a connecting rod 20, and each support sheet 21 is provided with a serrated contact point 22.

[0022] Compared with the prior art using 4 ribs 18 of the material tray 6 structure, this solution is now changed to 3 ribs 18, which is easier to weld and control precision. The previous support sheet 21 used a single point contact with the material roll barrel core, and now it is changed to a toothed multi-point contact, which improves the friction with the inner wall of the material roll barrel core and eliminates the slipping phenomenon. In addition, the transmission component and the support component of the material tray 6 are made and assembled separately, which can improve the concentricity of the entire material tray and reduce the assembly precision requirements, thereby improving the efficient production efficiency of the material tray 6, and making the later installation and maintenance more convenient.

[0023] Preferably, the plurality of fan heaters 9 are arranged at equal intervals. The advantage of such an arrangement is that the temperature in the hot air chamber 2 can be made relatively uniform, thereby making the material coil heated uniformly.

[0024] Preferably, a non-powered roller 11 is provided below the one or more material trays 6. The function of the powered roller is to lead out the lifting belt on the material roll.

[0025] Preferably, a transparent baffle is provided at the front of the material box 1. The transparent baffle can facilitate the operator to observe the situation in the material box 1.

[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
