[0002] Automated production equipment is widely used in various industrial equipment and other fields. The market demand is increasing, and the requirements for production cost efficiency are increasing faster and faster.

[0003] For example, when processing plastic products, hot melt sealing and cutting are required. These are two independent processes. If they are only done manually, the time efficiency of the entire line cannot be met. Moreover, this process is only a part of the entire production line, and the efficiency frequency is very high and cannot be interrupted.

[0004] When using automated production, if only the hot melt sealing and cutting are automated, there will be problems such as high production line manufacturing costs and difficulty in adjusting the production rhythm.

[0005] Therefore, there is a demand to realize automation at low cost and high efficiency while easily controlling the rhythm. Utility Model Content

[0030] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0031] The utility model is a hot melt sealing and cutting processing device for plastic product processing. Figure 1 In the figure, front and back refer to the direction of material movement. The material moves from the rear end to the front end. The driving force for the material movement is the traction device located at the front end of the device of the utility model. That is, for this device, the material is automatically sucked and pulled, and most automation equipment in the field uses automatic traction feeding, which can better guarantee the rhythm and spacing compared with the suction and traction structure.

[0032] Please continue to refer to Figure 1 The utility model is an automatic rotating material pulling and turning device, comprising two parallel transmission roller lines 100 arranged along the material conveying direction, and the transmission roller lines 100 are connected with the process devices at the front end and the rear end. In the device, a transmission roller 200, a hot melt sealing device 300 and a cutting device 400 are arranged in sequence between the transmission roller lines 100 along the material conveying direction.

[0033] Please refer to Figure 2 The shaft of the transmission roller 200 spans across the two ends of the transmission roller line 100, and the transmission roller 200 rotates when the material moves. In this way, the material conveying will be more stable, providing a more stable material state for the operation of the hot melt sealing device 300 at its rear end.

[0034] Please refer to Figure 3 , in order to describe clearly, Figure 3In the figure, one side of the transmission roller line 100 is hidden to show the internal structure. The hot melt sealing device 300 includes an upper welding head 310 and a lower welding head 320 which are arranged at the upper and lower ends of the conveying material, driven by a driving mechanism that moves up and down, and can be docked and separated. The material passes between the upper welding head 310 and the lower welding head 320, and hot melt sealing is achieved by docking and separation. Preferably, the upper welding head 310 and the lower welding head 320 use brass heating blocks, and then cooperate with mica insulation. For the selection of the driving mechanism, preferably, it can be driven by a cylinder, and a cylinder driver 330 connected thereto is set. The cylinder driver 330 has standard equipment, which will not be described again. Specifically, the cylinder driver 330 of the upper welding head 310 can be set on the cylinder fixing seat 340, and the cylinder driver 330 of the lower welding head 310 is fixed on the cylinder support plate 350. The cylinder fixing seat 340 may be fixed across the upper end of the conveying roller line 100 , and the cylinder supporting plate 350 may be fixed at the bottom of the conveying roller line 100 .

[0035] Combined with reference Figure 4 , the cutting device 400 includes a lower roller die 410 disposed between the transmission roller lines 100. Preferably, the lower roller die 410 adopts a rubber roller, more specifically, a rubber roller. The first transmission gear 420 driving the lower roller die 410 is disposed on the outer side of the transmission roller line 100. A cutting bearing seat 430 is disposed at the upper end of the transmission roller line 100, and the cutting bearing seat 430 corresponds to the transmission roller line 100 as a pair. A rotating turning cutter 440 is disposed between the cutting bearing seats 430 and is connected to the lower roller die 410 by rotation. On the outer side of the cutting bearing seat 430, that is, on the upper end of the same side as the first transmission gear 420, a second transmission gear 450 is disposed that is coaxial with the rotating turning cutter and meshes with the first transmission gear 420. This also forms a structure in which the lower roller die 410 and the rotating turning cutter 440 rotate in opposite directions, and thus the structure can achieve cutting of the material. The rotary cutting blade 440 rotates clockwise, while the lower rolling cutter die 410 rotates counterclockwise, so that the material can be prevented from being stretched and deformed by being clamped and driven by the lower rolling cutter die 410 and the rotary cutting blade 440 .

[0036] In this way, the cutting device 400 can drive and control the rotating cutting knife 440 and the lower rolling cutter die 410 at the same time through the meshing transmission of the two transmission gears, which can improve the cutting efficiency and facilitate the control of the production rhythm.

[0037] Please refer to Figure 4 and Figure 5 , Figure 4 is the state before the rotating cutting knife 440 performs cutting, and Figure 5 This is the state after the incision is completed. Figure 5In order to show the state of the rotary cutting blade 440, the transmission roller line 100 on one side is hidden. Therefore, for the rotary cutting blade 440, the lower roller die 410 is a cutting blade. Please refer to Figure 6 and Figure 7 In some embodiments, in order to facilitate the rotary cutting blade 440 to make a rotary cut, a chamfer 441 is provided on the cutting edge of the rotary cutting blade 440, that is, the surface that interfaces with the lower hob die 410. Then, the blade 442 of the rotary cutting blade 440 is set at the end of the chamfer 441.

[0038] As a drive for the cutting device 400, a driving device 460 coaxial with the rotating cutting blade 440 is arranged outside the cutting bearing seat 430, that is, opposite to the second transmission gear 450. Preferably, the driving device 460 can be a speed regulating motor, which can facilitate adjusting the working rhythm according to the structure of the entire production line.

[0039] Finally, the installation status of the automatic rotating material pulling and cutting device of the utility model is explained. Please refer to Figure 8 The table 1 is a working platform. At this time, the transmission roller line 100 is set at the gap of the working platform. A concave platform 110 can be set at the bottom of the transmission roller line 100, so that the concave platform can be stuck into the table 1. This is a common method in the industry and will not be described here.

[0040] Fig. 9 The bottom of the automatic rotating material pulling and cutting device of the utility model is intended to Fig.10 This is the bottom installation state during operation. The table top 1 is hollow. After the automatic rotating material pulling and turning device of the utility model can be inserted, since the bottom of the table top 1 is hollow, the entire hot melt sealing device 300 and the cutting device 400 are not restricted at the bottom, which is convenient for installation and use.

[0041] In this way, by continuously arranging the transmission roller 200, the hot melt sealing device 300 and the cutting device 400 on the transmission roller line 100, the structure is simple, and automated production can be achieved at low cost and high efficiency.

[0042] Please refer to Figure 2 In some embodiments, a line support plate 500 for supporting the material is provided between the transmission rollers 100 along the material conveying direction. The line support plate 500 is provided with rolling notches at the transmission rollers 200 and the lower roller die 410.

[0043] Please refer to Figure 1 In some embodiments, for safety, a protective cover 600 is provided on the outer periphery of the cutting device 400 of the automatic rotating material pulling and cutting device.

[0044] As mentioned above, this case protects an automatic rotating material pulling and cutting device, and all technical solutions that are the same or similar to this case should be shown to fall within the protection scope of this case.
