Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag bag-making equipment, in particular to a paper tube bin with smooth discharging. Background Art

[0002] During the processing and forming of plastic bags, the closed-end bag film blown by a film blowing machine needs to be wound up using a core tube, which is also called a paper tube in the industry. Moreover, after a plastic bag making machine unwinds a plastic film, it undergoes a series of processing and forming operations to process the bag body, and after the bag making is completed, the bags are collected. For continuous roll bags, such as common continuous roll garbage bags, continuous roll food bags, etc., they are all collected by winding them up with a paper tube.

[0003] During the winding process of both the film blowing machine and the bag making machine, when one winding is completed, for example, when setting the number or length of the wound bag bodies, it is necessary to replace the paper tube in the winding equipment. Therefore, a paper tube bin is provided to store multiple paper tubes that need to be replaced. The existing paper tube bin includes a paper tube storage bin, a rising channel, a tube feeding component, and a lifting component. The paper tubes are stacked in the paper tube storage bin, and the lowermost paper tube is pushed by the tube feeding component into the low position of the paper tube at the bottom of the rising channel, and then is grabbed by the lifting component and lifted along the rising channel and enters the high position of the paper tube at the top for standby. Although the existing paper tube bin can automatically supply paper tubes, however, due to the small weight of the paper tubes, it is easy to get stuck and the adjacent paper tubes become empty when entering the low position of the paper tube from the bottom of the paper tube storage bin, and the paper tubes cannot be output smoothly, affecting the normal operation of the production line.

[0004] Therefore, it is necessary to develop a paper tube bin with smooth discharging to address the above-mentioned defects. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a paper tube bin with smooth discharging, which can significantly improve the jamming situation of the paper tube bin and facilitate the stable and smooth output of paper tubes.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A paper tube bin with smooth discharging of the utility model includes a paper tube storage bin, a rising channel, a tube feeding component, and a lifting component, and further includes a rear baffle. The rear baffle is vertically arranged in the paper tube storage bin and serves as the rear limiting wall plate of the rising channel. An L-shaped bending plate is fixedly connected to the side of the rear baffle facing the paper tube storage bin. The bottom of the bending plate is a bottom limiting plate, and the bottom limiting plate is parallel to the inclined bottom plate of the paper tube storage bin; between the bottom limiting plate and the bottom plate of the paper tube storage bin is a single-tube feeding channel, and the height of the single-tube feeding channel is less than the diameter of two paper tubes and greater than the diameter of one paper tube. The bottom end of the single-tube feeding channel communicates with the low position of the paper tube.

[0008] Further, it further includes a left wall panel, a right wall panel, guide columns, and a double-headed lead screw. The left wall panel and the right wall panel are arranged face to face on the left and right sides of the paper tube bin and the rising channel and serve as the wall panels of the chamber. The three guide columns vertically penetrate through the left wall panel and the right wall panel, and the left wall panel and the right wall panel can slide left and right along the guide columns; the double-headed lead screw is parallel to the guide columns and is respectively connected to the left wall panel and the right wall panel through two nut sliders, and the double-headed lead screw can drive the left wall panel and the right wall panel to approach or move away synchronously.

[0009] Further, a handwheel is arranged at the right end of the double-headed lead screw.

[0010] Further, the number of the rear baffle plates is two, and they are respectively connected to the inner side walls of the left wall panel and the right wall panel through bolts. Waist-shaped holes for passing the bolts are formed in the connecting flanges of the rear baffle plates, and the long sides of the waist-shaped holes are arranged along the vertical direction.

[0011] Further, it further includes a pipe feeding claw assembly. The pipe feeding assembly includes a cylinder, a slider, and pipe feeding claw guide columns. The end of the piston rod of the cylinder is connected to the slider, and the pipe feeding claw guide columns protrude left and right from both sides of the slider. Two pipe feeding claw assemblies are connected to the pipe feeding claw guide columns in a guiding manner. An upward-opening paper tube low-level notch is arranged at the front end of the pipe feeding claw assembly, and the paper tube low-level notch coincides with the paper tube low level when the cylinder of the pipe feeding assembly is in the ejected state.

[0012] Further, a loosening tooth section is further arranged at the top of the pipe feeding claw assembly, and the loosening tooth section can contact the bottom surface of the bottom layer of paper tubes to push and loosen them when the cylinder of the pipe feeding assembly is in the ejected state.

[0013] Further, it further includes an anti-canopy air cylinder. The anti-canopy air cylinder is arranged on the top surface of the slider, and the piston rod of the anti-canopy air cylinder vertically protrudes upward to loosen the canopy-empty paper tubes.

[0014] Compared with the prior art, the beneficial technical effects of the present utility model are as follows:

[0015] For the paper tube bin with smooth discharging of the present utility model, by fixedly connecting an L-shaped bending plate to the side of the rear baffle plate facing the paper tube bin, and the bottom of the bending plate is set as a bottom limiting plate, the formed single-pipe feeding channel can only pass through one paper tube, that is, two paper tubes cannot enter the single-pipe feeding channel simultaneously, avoiding jamming. Through the cooperation of the single-pipe feeding channel and the pipe feeding assembly, only the single row of paper tubes in the single-pipe feeding channel is pushed during the forward pushing process when the pipe feeding assembly retreats to the rear position, avoiding the formation of a canopy-empty state at the entrance of the paper tube low level, and the feeding is smooth. The paper tube bin with smooth discharging of the present utility model can significantly improve the jamming situation of the paper tube bin and is convenient for stably and smoothly outputting paper tubes.

[0016] In addition, by arranging a slidable left wall panel and a right wall panel on the guide posts, the left wall panel and the right wall panel can be synchronously moved closer to or away from each other under the drive of the double-headed lead screw, thereby realizing the adjustment of the left and right widths of the chamber of the pipe storage bin and the rising channel, and adapting to the supply of paper tubes with different length dimensions. By drivingly connecting the sprockets on both sides through a transmission prism shaft, the chains on the two wall panels can be synchronously operated, and the two groups of corresponding hook claws on both sides can be synchronously lifted, avoiding skew during the lifting of the paper tube. By arranging waist-shaped holes in the vertical direction, the installation height of the rear baffle can be adjusted, and then the height of the single-pipe blanking channel can be adjusted, thereby being applicable to the supply of paper tubes with different diameters. By arranging guide posts for the pipe feeding claws on both sides of the slider and guiding the pipe feeding claw assembly, the distance can be changed following the movement of the wall panel, with good adaptability, ensuring pushing near both ends of the paper tube, realizing synchronous pushing, and avoiding the dislocation of the paper tube. By arranging a loose tooth section on the top of the main board of the pipe feeding claw assembly, the bottom surface of the bottom paper tube can be pushed and loosened, enabling the smooth blanking of the paper tube. By arranging an anti-awning air cylinder on the top surface of the slider, the anti-awning air cylinder can push and loosen the paper tube in the awning space above, causing it to fall by its own weight and then roll to the entrance of the single-pipe blanking channel.

Detailed implementation mode

[0025] The core of the present utility model is to provide a paper tube bin with smooth discharging, which can significantly improve the jamming situation of the paper tube bin and facilitate the stable and smooth output of paper tubes.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0027] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0028] Referring to the accompanying drawings, Figure 1 is a three-dimensional structural schematic diagram of the paper tube bin with smooth discharging of the present utility model; Figure 2 is a front view structural schematic diagram of the paper tube bin with smooth discharging of the present utility model; Figure 3 is Figure 2 a sectional structural schematic diagram of the A-A part of Figure 4 is a three-dimensional structural schematic diagram of the pipe feeding assembly of the present utility model; Figure 5 is a three-dimensional structural schematic diagram of the pipe feeding claw assembly of the present utility model; Figure 6 is a three-dimensional structural schematic diagram of the rear baffle of the present utility model.

[0029] In a specific implementation mode, as Figures 1 - 6As shown in the figure, the paper tube bin of the present utility model for smooth discharging includes a paper tube bin, a rising channel 12, a tube feeding assembly 6 and a lifting assembly 5. The paper tubes to be used are stacked in the paper tube bin. The tube feeding assembly 6 is arranged at the bottom of the paper tube bin and can assist in forwardly conveying the paper tubes to the low position 11 of the paper tubes. The lifting assembly 5 uses the method of dragging the claw 505 by the chain 503 to grab the paper tubes at the low position 11 of the paper tubes, lift them upward along the rising channel 12 and roll them to the high position 13 of the paper tubes at the top. A pushing tube cylinder 14 is also installed below the high position 13 of the paper tubes. A fork seat is installed at the end of the piston rod vertically protruding upward from the pushing tube cylinder 14. The fork seat can push the paper tubes at the high position 13 of the paper tubes upward into the working position. The important difference of the present utility model from the existing paper tube bin lies in that it further includes a rear baffle 9. The rear baffle 9 is vertically arranged in the paper tube bin and serves as the rear limiting wall plate of the rising channel 12. An L-shaped bending plate 901 is fixedly connected to the side of the rear baffle 9 facing the paper tube bin. The bottom of the bending plate 901 is the bottom limiting plate 902. The bottom limiting plate 902 is parallel to the inclined bottom plate of the paper tube bin. Between the bottom limiting plate 902 and the bottom plate of the paper tube bin is a single-tube discharging channel 10. The height of the single-tube discharging channel 10 is less than the diameter of two paper tubes and greater than the diameter of one paper tube. Preferably, the height of the single-tube discharging channel 10 is 1.2 times the diameter of the paper tube. The bottom end of the single-tube discharging channel 10 communicates with the low position 11 of the paper tubes.

[0030] By fixedly connecting the L-shaped bending plate 901 to the side of the rear baffle 9 facing the paper tube bin and setting the bottom of the bending plate 901 as the bottom limiting plate 902, the formed single-tube discharging channel 10 can only pass through one paper tube, that is, two paper tubes cannot enter the single-tube discharging channel 10 at the same time, avoiding jamming. Through the cooperation of the single-tube discharging channel 10 and the tube feeding assembly 6, only the single row of paper tubes in the single-tube discharging channel 10 is pushed forward during the backward and forward pushing process of the tube feeding assembly 6, avoiding the formation of a canopied empty state at the entrance of the low position 11 of the paper tubes, and the discharging is smooth. The paper tube bin of the present utility model for smooth discharging can significantly improve the jamming situation of the paper tube bin and facilitate the stable and smooth output of paper tubes.

[0031] In a specific embodiment of the present utility model, as Figures 1 - 3As shown in the figure, the paper tube bin of the present utility model for smooth discharging further includes a left wall panel 1, a right wall panel 2, guide columns 3 and a double-headed lead screw 4. The left wall panel 1 and the right wall panel 2 serve as the wall panels of the chamber and are arranged face to face on the left and right sides of the chamber of the paper tube bin and the rising channel 12. The bottoms of the left wall panel 1 and the right wall panel 2 are provided with inward flanges as the bottom edges to support the stacked paper tubes. Three guide columns 3 are vertically penetrated through the left wall panel 1 and the right wall panel 2, and guide sleeves are installed at the through holes of the wall panels on the guide columns 3. The left wall panel 1 and the right wall panel 2 can slide left and right along the guide columns 3. The double-headed lead screw 4 is a lead screw symmetrically provided with threaded sections with opposite thread directions at both ends. The double-headed lead screw 4 is parallel to the guide columns 3 and is respectively connected to the left wall panel 1 and the right wall panel 2 through two nut sliders. The double-headed lead screw 4 can drive the left wall panel 1 and the right wall panel 2 to approach or move away synchronously.

[0032] Specifically, as Figure 2 shown, a hand wheel 401 is provided at the right end of the double-headed lead screw 4.

[0033] By providing the slidable left wall panel 1 and right wall panel 2 on the guide columns 3, the left wall panel 1 and the right wall panel 2 can be synchronously approached or moved away under the drive of the double-headed lead screw 4, thereby realizing the adjustment of the left and right widths of the chambers of the tube bin and the rising channel 12 to adapt to the supply of paper tubes with different length dimensions.

[0034] In a specific embodiment of the present utility model, as Figure 1 and Figure 3 shown, the lifting assembly 5 further includes a reduction motor 501, sprockets 502 and a transmission prism shaft 504. Two groups of sprockets 502 are respectively rotatably connected to the inner side walls of the two wall panels. Each group of sprockets 502 includes two upper and lower sprockets 502 connected by a chain 503. The reduction motor 501 drives the bottom sprocket 502 on the outer wall of the wall panel. Prismatic holes are provided at the centers of the two upper sprockets 502 and are connected through the transmission prism shaft 504. Both ends of the transmission prism shaft 504 are supported on the brackets outside the paper tube bin through bearings.

[0035] By driving the sprockets 502 on both sides through the transmission prism shaft 504, the chains 503 on the two wall panels can run synchronously, realizing the synchronous lifting of the two groups of corresponding hook claws 505 on both sides and avoiding skewing during the paper tube lifting process.

[0036] In a specific embodiment of the present utility model, as Figure 6 shown, the number of the rear baffle plates 9 is two, which are respectively connected to the inner side walls of the left wall panel 1 and the right wall panel 2 by bolts. Waist-shaped holes 903 for passing through the bolts are provided on the connecting flanges of the rear baffle plates 9. The long sides of the waist-shaped holes 903 are arranged along the vertical direction.

[0037] Obviously, the kidney-shaped holes here can also be opened on the side walls of the left wallboard 1 and the right wallboard 2. It is only necessary to open round holes on the connecting flanges of the rear baffle 9, which can also achieve the adjustment of the height position of the rear baffle 9. Similar simple deformation methods all fall within the protection scope of the present invention.

[0038] Through the arrangement of the kidney-shaped holes 903 opened in the vertical direction, the installation height of the rear baffle 9 can be adjusted, and then the height of the single-pipe blanking channel 10 can be adjusted, so as to be applicable to the supply of paper tubes with different diameters.

[0039] In a specific embodiment of the present invention, as Figures 2 - 5 shown, the paper tube bin with smooth discharging of the present invention further includes a tube feeding claw assembly 7. The tube feeding assembly 6 includes a cylinder, a slider 601 and a tube feeding claw guide post 602. The end of the piston rod of the cylinder is connected to the slider 601. A guide rod and a guide sleeve are arranged between the slider 601 and the cylinder mounting plate, ensuring that the slider 601 moves horizontally back and forth in a straight line along the front and rear directions. The tube feeding claw guide posts 602 protrude leftward and rightward from both sides of the slider 601. Two tube feeding claw assemblies 7 are connected to the tube feeding claw guide posts 602 through longitudinal guide sleeves 704. A transverse guide sleeve 703 is further arranged on the outer side of the tube feeding claw assembly 7. Lower edge plates 15 are connected to the bottoms of the left wallboard 1 and the right wallboard 2. A transverse guide rod is arranged between the inner folded edges of the lower edge plates 15. The transverse guide sleeve 703 slides on the transverse guide rod. An upward-opening paper tube low-position notch 701 is arranged at the front end of the tube feeding claw assembly 7. When the cylinder of the tube feeding assembly 6 is in the ejected state, the paper tube low-position notch 701 coincides with the paper tube low position 11.

[0040] Obviously, as Figure 4 shown, the cylinder of the tube feeding assembly 6 can also be a hydraulic cylinder. A guide rod and a guide sleeve are arranged between the slider 601 and the hydraulic cylinder mounting plate. A proximity switch bracket 603 is further mounted on the back of the hydraulic cylinder mounting plate. A proximity switch is mounted on the proximity switch bracket 603. The proximity switch collects two limit positions of the guide rod to determine the stroke range of the hydraulic cylinder.

[0041] Specifically, as Figure 5 shown, a loosening tooth section 702 is further arranged on the top of the tube feeding claw assembly 7. When the cylinder of the tube feeding assembly 6 is in the ejected state, the loosening tooth section 702 can contact the bottom surface of the bottom paper tube for pushing and loosening.

[0042] By arranging the tube feeding claw guide posts 602 on both sides of the slider 601 and guiding the tube feeding claw assembly 7, the distance can be changed synchronously after the wallboard moves, with good adaptability, ensuring that the pushing is carried out near both ends of the paper tube, realizing synchronous pushing and avoiding the situation of paper tube misalignment. By arranging the loosening tooth section 702 on the main board top of the tube feeding claw assembly 7, the bottom surface of the bottom paper tube can be pushed and loosened, enabling the paper tube to be discharged smoothly.

[0043] In a specific embodiment of the present utility model, as shown in Figure 3 and Figure 4 , the paper tube bin of the present utility model for smooth discharging further includes an anti-jamming air cylinder 8, which is arranged on the top surface of the slider 601. The piston rod of the anti-jamming air cylinder 8 vertically protrudes upward to loosen the jammed paper tubes.

[0044] It should be noted that when the cylinder of the tube feeding assembly 6 is in the protruding state, the paper tube directly above the anti-jamming air cylinder 8 has not yet entered the single-tube feeding channel 10. That is, the anti-jamming air cylinder 8 is located at the bottom of the middle position of the paper tube bin at this time. If the distance between the two wall panels and the length distance of the paper tubes are relatively large and the diameter of the paper tubes is relatively large, the stacked paper tubes will be skewed in the paper tube bin and jammed between the two wall panels, forming a jamming situation, and no paper tubes will enter the single-tube feeding channel 10 anymore.

[0045] By arranging the anti-jamming air cylinder 8 on the top surface of the slider 601, the anti-jamming air cylinder 8 can push and loosen the jammed paper tubes above, so that they fall by their own weight and then roll to the entrance of the single-tube feeding channel 10.

[0046] The working principle of the paper tube bin of the present utility model for smooth discharging: First, adjust the paper tube bin according to the specifications of the paper tubes. Rotate the handwheel 401, and the double-headed lead screw 4 drives the left wall panel 1 and the right wall panel 2 to approach or move away synchronously, so as to realize the adjustment of the distance between the left wall panel 1 and the right wall panel 2 to adapt to the length of the paper tubes and avoid too large or too small gaps. Loosen the bolts at the waist-shaped holes 903 so that the rear baffle 9 can move up and down to adjust the height of the single-tube feeding channel 10, so as to adapt to the diameter of the paper tubes. The height of the single-tube feeding channel 10 is 1.2 times the diameter of the paper tubes. During the tube feeding process, each time the cylinder of the tube feeding assembly 6 acts, the tube feeding claw assembly 7 makes a forward-backward-forward movement stroke, and the tube feeding claw assembly 7 conveys the paper tube at the front end in the single-tube feeding channel 10 to the paper tube low position 11. At the same time, before the tube feeding claw assembly 7 retreats each time, the anti-jamming air cylinder 8 acts, and its piston rod quickly moves up vertically several times to loosen the jammed paper tubes. Then, the reduction motor 501 acts to drive the sprocket 502 to rotate. The hook claw 505 grabs the paper tube from the paper tube low position 11 and lifts it upward along the ascending channel 12. When it runs to the top, the paper tube rolls off the hook claw 505 from the front side bridge and enters the paper tube high position 13. The pushing cylinder 14 acts to drive the fork seat to push up the paper tube falling into the paper tube high position 13 into the winding working position. When a new paper tube needs to be wound, repeat the above tube feeding action process.

[0047] The paper tube bin of the present utility model with smooth discharging. By fixedly connecting an L-shaped bending plate 901 on the side of the rear baffle 9 facing the paper tube bin, the bottom of the bending plate 901 is set as a bottom limiting plate 902. The formed single-tube discharging channel 10 can only pass through one paper tube, that is, two paper tubes cannot enter the single-tube discharging channel 10 simultaneously, avoiding jamming. Through the cooperation of the single-tube discharging channel 10 and the tube feeding assembly 6, during the process of the tube feeding assembly 6 pushing forward after retreating, only the single row of paper tubes in the single-tube discharging channel 10 is pushed, avoiding the formation of a vacant state at the entrance of the low position 11 of the paper tubes, and the discharging is smooth. The paper tube bin of the present utility model with smooth discharging can significantly improve the jamming situation of the paper tube bin and facilitate the stable and smooth output of paper tubes. In addition, by arranging a slidable left wall panel 1 and a right wall panel 2 on the guide posts 3, the left wall panel 1 and the right wall panel 2 can be synchronously approximated or separated under the drive of the double-headed lead screw 4, thereby realizing the adjustment of the left and right widths of the chambers of the tube bin and the rising channel 12 to adapt to the supply of paper tubes with different length dimensions. By drivingly connecting the sprockets 502 on both sides through the transmission prism shaft 504, the chains 503 on the two wall panels can operate synchronously, realizing the synchronous lifting of the two groups of corresponding hook claws 505 on both sides, avoiding skewing during the lifting of the paper tubes. By arranging the waist-shaped holes 903 opened in the vertical direction, the installation height of the rear baffle 9 can be adjusted, and then the height of the single-tube discharging channel 10 can be adjusted, thereby being applicable to the supply of paper tubes with different diameters. By arranging the tube feeding claw guide posts 602 on both sides of the slider 601 to guide the tube feeding claw assembly 7, the spacing can also be changed following the movement of the wall panel, with good adaptability adjustment, ensuring pushing near both ends of the paper tube and realizing synchronous pushing to avoid the situation of paper tube misalignment. By arranging the loosening tooth section 702 on the top of the main board of the tube feeding claw assembly 7, the bottom surface of the bottom-layer paper tube can be pushed and loosened, enabling the smooth discharging of the paper tubes. By arranging the anti-vacancy air cylinder 8 on the top surface of the slider 601, the anti-vacancy air cylinder 8 can push and loosen the paper tubes in the upper vacant state, making them fall by their own weight and then roll to the entrance of the single-tube discharging channel 10.

The same or similar parts among the various embodiments can be referred to each other. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0049] The embodiments described above are only descriptions of the preferred modes of the present utility model and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
