Description

Technical Field

[0001] This utility model relates to the field of woven bag processing technology, and in particular to a device for easily tearing and rolling up finished woven bags. Background Technology

[0002] Woven bags are packaging bags made primarily of polypropylene or polyethylene, which are extruded and stretched into flat filaments, then woven, braided, and made into bags. They are widely used for packaging materials such as powders and granules.

[0003] In the production process of woven bags, the cylindrical structure needs to be closed at one end and then cut to make the woven bag usable. This pre-cut woven bag will cause the woven bag to need to be packed for storage, which is inconvenient. Therefore, this application discloses a woven bag finished product tearing and rolling device to facilitate the storage of woven bags and eliminate the need for packing before storage. Utility Model Content

[0004] The purpose of this invention is to address existing problems by providing a device for easily tearing and rolling woven bags.

[0005] This utility model is achieved through the following technical solution:

[0006] A device for easily tearing and rolling woven bags includes a frame with symmetrically mounted side plates. An inlet roller and a take-up roller are respectively mounted at both ends of the side plates. One end of the take-up roller is connected to a drive mechanism. A tie plate is connected at intervals in the middle of the side plates. An anvil of an anvil mechanism is set between the tie plates. A cutting mechanism is set directly above the anvil. The cutting mechanism is suspended on a support frame by a hydraulic cylinder. The support frame is connected to the frame.

[0007] As a further improvement to the above solution, the anvil base mechanism includes anvils symmetrically arranged below the edges of the deck board, with sliding rods connected at intervals on the opposite sides of the anvils. The sliding rods are fitted with springs, and the end of the sliding rod away from the anvils is sleeved on a rod base. The end of the sliding rod away from the anvils is connected to a rod cap, and the rod base is connected to the lower surface of the deck board.

[0008] A V-shaped groove is formed by an inclined surface on a symmetrical anvil. During the process of the cutter cutting the woven bag, the blade of the cutter acts on the edge of the anvil through the woven bag. The symmetrical anvil moves outward to both sides, which pushes the slide rod to move, thus preventing the blade of the cutter from becoming dull and reduced. At the same time, the force of the spring is used to prevent the anvil from moving outward and to cut the woven strip.

[0009] As a further improvement to the above solution, the cutting mechanism includes a cutting blade, which is arranged between symmetrical anvils and mounted on a blade holder, which is connected to the bottom of the plate base.

[0010] The blade holder is fixed by a plate base, which is used to mount the cutting blade so that it can be used in conjunction with symmetrical anvils for cutting.

[0011] As a further improvement to the above solution, the plate base is provided with horizontal bars symmetrically and at intervals on both sides, with vertical bars sleeved through the horizontal bars, springs 2 sleeved on the vertical bars, pressure plates connected to the lower ends of the vertical bars, and stop caps connected to the upper ends of the vertical bars.

[0012] The crossbar moves downward with the plate base, applying pressure to the second spring. The spring's reaction force causes the pressure plate to press against the plate, thus holding the woven bag in place and preventing it from being cut.

[0013] As a further improvement to the above solution, a guide rod is vertically connected to the plate base of the cutting mechanism, and the guide rod passes through the support frame;

[0014] The guide rod ensures the balance and stability of the rod holder and the structural components such as the tool holder and cutter installed below it during the driving displacement process of the hydraulic cylinder.

[0015] As a further improvement to the above solution, the cutting edge of the cutter is provided with several arc-shaped notches at intervals, and the end of the cutting edge is provided with a notch; the woven bag cannot be cut by the intervals on the cutting edge, so the cutter with notches is used to make interval cuts on the woven bag, so that the woven bag can be torn along the cut after it is rolled up.

[0016] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. By introducing a roller to guide the tubular woven bag, a hydraulic cylinder drives the cutter to cut the tubular woven bag during the stacking process. At the same time, the anvil is placed under the cutter to cooperate with the cutter. However, the notch on the cutter cannot cut the tubular woven bag, so the tubular woven bag is cut in an intermittent state. After the winding roller winds the woven bag, it is convenient for tearing the woven bag in the subsequent process. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figures 1 to 4As shown, a woven bag finishing device for easy tearing and winding includes a frame 1. Side plates 2 are symmetrically installed on the frame 1. An inlet roller 8 and a winding roller 3 are respectively installed at both ends of the side plates 2. One end of the winding roller 3 is connected to a drive mechanism. The drive mechanism is a motor 7 that drives the main pulley 6 sleeved on it to rotate. The main pulley 6 drives the driven pulley 4 to rotate through the belt 5. The driven pulley 4 drives the winding roller 3 coaxially connected to rotate to achieve the purpose of winding. After winding, a pressure plate 1716 is rotatably set at one end of the side plate to limit and fix the end of the winding roller 3 away from the drive mechanism. The pressure plate 1716 is rotated to facilitate the removal of the rolled woven bag. The middle of the side plates 2 is connected to the overlapping plates 10. An anvil strip 111 of the anvil mechanism 11 is set between the overlapping plates 10. A cutter mechanism 121 is set directly above the anvil strip 111. The cutter mechanism 121 is suspended on the support frame 15 by a hydraulic cylinder 13. The support frame 15 is connected to the frame 1.

[0023] As a further improvement to the above solution, the anvil base mechanism 11 includes anvil bars 111 symmetrically arranged below the edges of the approach plate 10, with sliding rods 112 connected at intervals on the opposite side of the anvil bars 111, the sliding rods 112 being fitted with springs 113, the end of the sliding rods 112 away from the anvil bars 111 being sleeved on a rod seat 114, the end of the sliding rods 112 away from the anvil bars 111 being connected to a rod cap 115, and the rod seat 114 being connected to the lower surface of the approach plate 10.

[0024] A V-shaped groove is formed by an inclined surface on the symmetrical anvil 111. During the process of the cutter 121 cutting the woven bag, the cutting edge of the cutter 121 applies force to the edge of the anvil 111 through the woven bag. The symmetrical anvil 111 moves outward to both sides, which pushes the slide bar 112 to move, thus preventing the cutting edge of the cutter 121 from becoming dull and reduced. At the same time, the force of the spring 113 prevents the anvil 111 from moving outward and cuts the woven strip.

[0025] As a further improvement to the above solution, the cutting blade 121 mechanism 12 includes a cutting blade 121, which is disposed between symmetrical anvils 111. The cutting blade 121 is mounted on a blade holder 122, which is connected to the bottom of the plate holder 123.

[0026] The blade holder 122 is fixed by the plate base 123, and the blade holder 122 is used to install the cutter 121 so that the cutter 121 can cooperate with the symmetrical anvil 111 to make cuts.

[0027] As a further improvement to the above solution, the plate base 123 is provided with symmetrical and spaced horizontal bars 20 on both sides, with vertical bars 18 sleeved through the horizontal bars 20, and springs 19 installed on the vertical bars 18. The lower end of the vertical bars 18 is connected to a pressure plate 17, and the upper end of the vertical bars 18 is connected to a stop cap 21; the vertical bars 18 are hoisted by the stop cap 21.

[0028] The crossbar 20 moves downward with the plate base 123, and applies pressure to the spring 19 through the crossbar 20. The reaction force of the spring causes the pressure plate 17 to press on the plate 10 to hold the woven bag in place, so as to limit the woven bag and ensure that the cutting of the woven bag is not affected.

[0029] As a further improvement to the above solution, a guide rod 123 is vertically connected to the plate base 123 of the cutter 121 mechanism 12, and the guide rod 123 passes through the support frame 15.

[0030] The guide rod 123 ensures the balance and stability of the rod seat 114 and the structural components such as the tool holder 122 and the cutter 121 installed below it during the driving displacement process of the hydraulic cylinder 13.

[0031] As a further improvement to the above solution, the cutting blade 121 has several arc-shaped notches 124 spaced apart on its cutting edge, and the end of the cutting edge is also provided with a notch 124. The woven bag cannot be cut through the spaced notches 124 on the cutting edge. Therefore, the cutting blade 121 with notches 124 is used to make spaced cuts on the woven bag, so that the woven bag can be torn along the cut after it is rolled up.

[0032] The working principle of a woven bag tearing and winding device is as follows: The tubular woven bag is guided by the roller 8. During the process of passing through the plate 10, the hydraulic cylinder 13 drives the cutter 121 to cut the tubular woven bag. At the same time, the anvil is placed under the cutter 121 to cooperate with the cutter 121 to cut. However, the notch 124 on the cutter 121 cannot cut the tubular woven bag. Therefore, the tubular woven bag is cut in an intermittent state. After the winding roller 3 winds the woven bag, it is convenient for tearing the woven bag in the subsequent process.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
