Description

Technical Field

[0001] The present invention relates to the field of packaging tape production, and in particular to a packaging tape production line. Background Art

[0002] At present, the production efficiency of packaging tape production lines is relatively low, and the speed connection between production processes is poor.

[0003] The production efficiency of the packaging tape production line is greatly affected by the melting process, and the melting process must be controlled at a constant temperature to ensure the strength and quality of the packaging tape. Therefore, the production efficiency cannot be improved by increasing the temperature to reduce the viscosity of the molten raw materials.

[0004] On the other hand, during the drying process, the existing drying device cannot eliminate the internal stress, and it is often necessary to set up a separate pulling and forming machine after the drying device to perform an additional process.

[0005] The embossing and coiling devices of the entire packaging tape production line need to be replaced because they need to adapt to different types of packaging tapes. When replacing the embossing and coiling devices on the existing production line, the entire set is generally replaced, or a dedicated production line is set up separately, which is costly and not good for the production rhythm.

[0061] The structure of its specific components is as follows:

[0062] Melt filtration device 1010:

[0063] This embodiment provides a melt filtering device 1010, see Figure 1 and Figure 2 , the melt filtering device 1010 comprises a conical filter sheet 1100;

[0064] The conical filter plate 1100 is a frustum-shaped housing, and filtering holes are arranged on the side of the conical filter plate 1100;

[0065] The conical filter sheet 1100 has a large end and a small end that are relatively arranged, a shaping sheet 1200 is welded and fixed to the small end, and a fixing piece 1300 for fixing the melt filtering device 1010 is welded and fixed to the large end;

[0066] The fixing member 1300 is provided with a mounting hole 1301 .

[0067] The conical filter 1100 filters the molten raw material and removes impurities. The pure molten raw material is cooled and formed into a packing tape in the next step. The shape of the conical filter 1100 can increase the filtering area and improve efficiency. On the other hand, the conical setting can prevent impurities from accumulating in the filter holes, which will cause a large number of filter holes to be blocked due to long-term use. The shaping pieces 1200 at the large and small ends can keep the conical filter 1100 in a frustum-shaped shape and will not collapse or deform during the extrusion process. The mounting hole 1301 provided on the fixing member 1300 is used to install the melt filtering device 1010 into the channel tube.

[0068] In this embodiment, the fixing member 1300 includes a shaping ring 1310 and a fixing reverse edge 1330; the inner side of the shaping ring 1310 is fixedly connected to the conical filter 1100, and the outer side of the shaping ring 1310 is fixedly connected to the fixing reverse edge 1330. The fixing reverse edge 1330 is parallel to the axial direction of the conical filter 1100, and a plurality of mounting holes 1301 are arranged at intervals in the circumferential direction on the fixing reverse edge 1330. Bolts are installed through the mounting holes 1301 to fix the conical filter 1100 to the inner side of the channel tube.

[0069] In this embodiment, the fixed reverse edge 1330 is parallel to the axis of the conical filter 1100 so that there is a containing space between the conical filter 1100 and the fixed reverse edge 1330. During use, impurities will be pushed into this containing space for accommodation without clogging the filter holes.

[0070] In other embodiments, the fixing member 1300 may be made into a flange shape, that is, the end of the shaping ring 1310 in this embodiment is thickened to form a fixing reverse edge 1330, and the plane where the fixing reverse edge 1330 is located is perpendicular to the axial direction of the conical filter plate 1100. Then the fixing member 1300 is installed at the end of the outlet of the channel pipe.

[0071] In order to ensure the sealing performance of the melt filtering device 1010, a sealing groove 1331 for clamping a sealing ring is provided on the outer side of the fixed reverse edge 1330. The sealing ring can be a heat-resistant sealing member such as a sealing steel ring.

[0072] A guide plate (not shown in the figure) is arranged on the side of the shaping plate 1200 away from the conical filter plate 1100, and at least two spiral guide plates are arranged in an annular array on the shaping plate 1200, so that the molten material close to the shaping plate 1200 can be naturally stirred before entering the conical filter plate 1100.

[0073] In this embodiment, a magnet is provided on the shaping ring 1310 , and the magnet can adsorb iron-containing impurities on the shaping ring 1310 .

[0074] Drying device 2001:

[0075] See also Figure 3 and Figure 4 , the drying device 2001 includes a drying oven 2010 and a transfer box 2030;

[0076] A winding roller group 2100 for pulling the packaging belt is arranged in the conveying box 2030, and the winding roller group 2100 includes a variable speed roller group composed of a first roller 2110 with a large diameter and a second roller 2130 with a small diameter;

[0077] The oven 2010 is arranged on the upper side of the conveying box 2030, and an air hole leading to the winding roller group 2100 is arranged on the side of the oven 2010 close to the conveying box 2030; an opening and closing cover 2210 is arranged on the side end of the oven 2010, and the opening and closing cover 2210 is hinged to the box body of the oven 2010.

[0078] In this embodiment, the packaging belt is tightened by pulling it around the roller group 2100, and internal stress is generated in the packaging belt. However, due to the toughness of the packaging belt, the internal stress can be maintained without being broken. The packaging belt is then sent to the oven 2010, and a plurality of heating rods are arranged above the inner shell of the oven 2010. The heat generated by the heating rods dries the packaging belt and eliminates the internal stress in the packaging belt. At this time, the packaging belt is stretched and the internal stress is eliminated while being dried.

[0079] Specifically, the air holes can also be set to pre-dry the packaging belt in the lower conveying box 2030. Since the packaging belt shakes during the conveying process, the excess water will be shaken off. Therefore, most of the surface water can be removed by heat drying in this process. However, the internal stress in the packaging belt cannot be eliminated and the packaging belt cannot be dried thoroughly.

[0080] In order to control the direction of hot air in the oven 2010, an exhaust member for extracting gas in the conveying box 2030 is provided at one end of the oven 2010. The exhaust member may be a blower. In other embodiments, the exhaust member may be provided at one side of the conveying box 2030 to increase the amount of hot air entering the conveying box 2030.

[0081] In this embodiment, the drying device 2001 further includes a cooling member 2300, which is disposed on a side of the oven 2010 away from the transfer box 2030. The cooling member 2300 cools the oven 2010. Specifically, the cooling member 2300 in this embodiment is a water tank, and a water cooling pipe can be disposed on a side of the water tank close to the oven 2010. The water in the water tank flows in the water cooling pipe, ensuring that the water in the water cooling pipe always has a relatively low temperature.

[0082] Specifically, the water tank can not only be used to cool one side of the oven 2010, but can also be integrated as a cooling member 2300 of the packaging belt. After the packaging belt solidifies, it has a certain temperature and is relatively soft and not easy to be formed. At this time, it can be cooled in the water tank. In order to cool the packaging belt, it is necessary to pull the packaging belt in the water tank. A cooling roller group 2500 is provided on the water tank. The cooling roller group 2500 provides a small tension force as long as the packaging belt can be pulled normally. Therefore, the cooling member 2300 provided by the present invention has two functions: cooling the packaging belt to ensure the molding of the packaging belt; cooling the oven 2010 to ensure the normal operation of the oven 2010.

[0083] The drying device 2001 further includes a drying lead part, which includes two groups of guide rollers 2413 groups 2410 respectively arranged at both ends of the oven 2010, wherein the ends of the speed-changing roller group of one group of guide rollers 2413 groups 2410 are matched. The guide rollers 2413 groups 2410 include a fixing rod 2411 and a guide roller 2413, wherein the fixing rod 2411 is provided with an oblong hole, and an installation rod is provided on one axial side of the guide roller, and the installation rod passes through the oblong hole and is matched with the fixing bolt 4350. The two groups of guide rollers 2413 groups 2410 are used to adjust the distance between the packaging belt and the heating rod, so that the distance between the packaging belt and the heating rod can be adjusted when drying packaging belts of different types and specifications.

[0084] Specifically, the drying device 2001 also includes a belt discharge portion for transporting the dried packaging belt out of the drying device 2001, and the belt discharge portion includes two belt pressing rollers 2430, which are arranged in parallel, and a belt pressing seam for pressing the packaging belt is provided between the two belt pressing rollers 2430.

[0085] Embossing device 3001:

[0086] See also Figure 5 and Figure 6 , the embossing device 3001 comprises a mounting frame 3100, a first driving member 3200, a synchronous transmission group 3300 and two embossing rollers 3400;

[0087] The synchronous transmission group includes two meshing transmission gears 3310, wherein the gear shaft of one transmission gear 3310 is cooperatively connected with the output end of the first driving member 3200;

[0088] The embossing roller 3400 is rotatably disposed in the mounting frame 3100. The embossing roller 3400 includes a shaft body. The shaft body of each embossing roller 3400 is circumferentially limitedly connected to a transmission gear 3310. In this embodiment, the circumferentially limited connection is achieved by interference fit with the bearing.

[0089] An embossing seam for embossing the packaging tape is formed between the two embossing rollers 3400, and one end of the embossing roller 3400 away from the transmission gear 3310 is rotatably connected to the mounting frame 3100;

[0090] The mounting frame 3100 is provided with a mounting cover 3500 for mounting the shaft end of the embossing roller 3400, a mounting hole 1301 is provided in the middle of the mounting cover 3500, a bearing for connecting the shaft end of the embossing roller 3400 is provided on the inner wall of the mounting hole 1301, and the mounting cover 3500 is detachably connected to the mounting frame 3100. The outer side of the mounting cover 3500 is provided with a reverse edge forming a flange, which is fixed to the mounting frame 3100 by bolts.

[0091] The embossing roller 3400 installed by the installation cover 3500 can be directly pulled out for disassembly, replacement and maintenance after the installation cover 3500 is removed. When the surface pattern of the packaging tape needs to be changed, the embossing roller 3400 can be replaced. The synchronous transmission group allows two transmission gears 3310 to drive the two embossing rollers 3400 to rotate respectively, thus avoiding the defect of easy sliding and misalignment caused by one embossing roller 3400 being active and the other embossing roller 3400 being driven in the prior art.

[0092] In this embodiment, an embossing skin (not shown in the figure) is arranged on the outside of the embossing roller 3400, and the embossing skin includes a flange. When the embossing skin is wrapped and arranged on the outside of the embossing roller 3400, the flange is located at both ends of the embossing roller 3400 and fits with the end surface of the embossing roller 3400. The flange is provided with a mounting through hole, and the embossing roller 3400 is provided with a threaded hole at a position corresponding to the mounting through hole. By providing the embossing skin, the pattern can be changed directly by replacing the embossing skin without replacing the embossing roller 3400 as a whole, which is convenient for the storage of parts and also saves costs.

[0093] The mounting frame 3100 includes a base 3010, a first driving member 3200 is fixedly arranged in the base 3010, and the output end of the first driving member 3200 is in transmission cooperation with the transmission gear 3310 through a synchronous belt 3330. The first driving member 3200 is installed on the base 3010 to lower the center of gravity of the embossing device 3001, and has better stability. In this embodiment, the four corners of the base 3010 are also provided with shock-absorbing feet 3011, and the bottom of the shock-absorbing feet 3011 is provided with rubber pads, which can buffer the vibration generated when the embossing device 3001 is working.

[0094] In this embodiment, in order to keep the embossing device 3001 in a clean and safe working state, a protective cover 3600 is provided on the outside of the mounting frame 3100. The protective cover 3600 mainly covers one end of the synchronous transmission group 3300, which can prevent the staff from inadvertently touching and causing work injuries, and on the other hand, it can also prevent dust from entering the synchronous transmission group 3300, causing the transmission gear 3310 to work abnormally or even cause synchronization failure.

[0095] In this embodiment, a tape guide roller 3710 is disposed on the side of the mounting frame 3100, and the axial direction of the tape guide roller 3710 is parallel to the axial direction of the embossing roller 3400. Two tape stoppers 3730 are also disposed at positions corresponding to the mounting frame 3100 and the tape guide roller 3710, and a gap is formed between the two tape stoppers 3730 for the packaging tape to pass through the tape guide.

[0096] By setting the tape guide roller 3710, the packaging tape can enter the embossed seam at a minimum angle to reduce the risk of the packaging tape breaking, and the two tape stoppers 3730 can ensure that the installation tape does not slip out of the embossed seam.

[0097] In this embodiment, a traction roller is also provided on the side of the mounting frame 3100.
