Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of bag making machine technology, and more specifically, to a double-layer non-stretch heat-sealing cold-cutting bag making machine. Background Technology

[0002] The double-layer non-stretch heat-sealing and cold-cutting bag making machine is an automated equipment specifically designed for producing double-layer plastic packaging bags. Its core feature is that it is non-stretching, meaning that the material does not undergo stretching deformation, heat sealing, or cold cutting during processing. It is suitable for packaging scenarios with high requirements for dimensional accuracy, sealing performance, and cut quality.

[0003] During the production of packaging bags, the film is conveyed through various processes by a conveyor device to finally form a packaging bag, which is then transported to a collection plate outside the device. When several packaging bags are pushed out, workers usually collect and pack them at the end of the device. However, after the packaging bags are pushed out, it is difficult to stack them neatly together. Therefore, workers need to manually stack a group of packaging bags and then tie them together with rubber bands or straps, which is quite laborious. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a double-layer non-stretch heat-sealing cold-cutting bag making machine, which solves the technical problem in the prior art that after the packaging bags are produced and extruded, it is difficult to arrange several packaging bags neatly, requiring workers to manually arrange them neatly.

[0005] According to one aspect, at least one embodiment of this disclosure provides a double-layer non-stretch heat-sealing cold-cutting bag making machine, including a bag making machine body, a support plate, a packaging box, a pusher plate, and a horizontal pushing assembly. The support plate is fixedly installed on the side of the bag making machine body, and two of the packaging boxes are slidably installed on the top of the support plate. Four pusher plates are provided, with each pair of pusher plates forming a group. The two groups of pusher plates are respectively disposed in two packaging boxes by two pusher assemblies. The horizontal pushing assembly is disposed on the support plate.

[0006] Furthermore, the alignment assembly includes an electric cylinder, a connecting rod, a movable rack, a rotating shaft, a rotating gear, and a transmission assembly. The electric cylinder is installed on one side of the assembly box, and the output end of the electric cylinder is fixedly connected to the side of one of the alignment plates in one group. The connecting rod is fixedly installed at the top of each group of alignment plates, and the movable rack is fixedly installed on the side of the connecting rod. Two rotating shafts are rotatably mounted on the side of the assembly box via a mounting plate. The rotating gears are fixedly installed on the rotating shafts, and the two rotating gears mesh with the two movable racks respectively. The transmission assembly is located on the side of the assembly box.

[0007] Furthermore, the transmission assembly includes a mounting bracket, a drive shaft, drive gears, and drive gear rings. The mounting bracket is fixedly mounted on the side of the assembly box. The drive shaft is rotatably mounted on the mounting bracket. Both ends of the drive shaft are fixedly mounted with the drive gears. The drive gears are fixedly mounted on the rotating shaft, and the two drive gears mesh with the two drive gear rings respectively.

[0008] Furthermore, the horizontal pushing assembly includes a support cover, a reciprocating screw, a motor, and a pushing frame. The support cover is fixedly mounted on the support plate, the reciprocating screw is rotatably mounted inside the support cover, and a matching crescent-shaped slider is mounted on the reciprocating screw. The motor is mounted on the side of the support cover, and the output end of the motor is coaxially connected to the reciprocating screw. The pushing frame is fixedly mounted on both sides of the crescent-shaped slider, and the two pushing frames are respectively fixedly connected to the two mounting frames.

[0009] In order to move the complete box to the position where the packaging bag falls, positioning rods are further fixedly installed on both sides of the support plate.

[0010] In order to enable the crescent-shaped slider to move horizontally on the reciprocating lead screw, the inner bottom wall of the support cover is provided with a sliding groove, a limit block is slidably installed in the sliding groove, and the top end of the limit block is fixedly connected to the bottom end of the crescent-shaped slider.

[0011] In order to enable the pusher plate to push the packaging bag falling into the packaging box from all directions, the length of the pusher plate is consistent with the internal length of the packaging box.

[0012] In order to allow the two assembled boxes to slide on the support plate, the top of the support plate is provided with a sliding groove, and both assembled boxes are slidably mounted on the support plate.

[0013] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, when collecting packaging bags, one of the packaging boxes can be moved to the feeding port of the bag making machine body by a horizontal pushing component, so that the packaging bags can fall into the packaging box after falling. Then, the two sides of the packaging bags in the packaging box are pushed to align by a pushing component, which is more convenient than manual layout. 2. In this disclosure, after one of the packaging boxes is filled, another packaging box can be moved to the discharge port by the horizontal pushing component, so that the packaging bags in the other packaging box can be collected and the falling packaging bags can be collected and arranged simultaneously. In summary, this device, through the cooperation of the support plate, the packaging box, the alignment plate, and the horizontal pushing component, can arrange the finished packaging bags, which is more labor-saving than manual arrangement by workers.

[0017] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0018] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0019] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-6 As shown, it illustrates a double-layer non-stretch heat-sealing cold-cutting bag making machine according to an embodiment of the present disclosure, including a bag making machine body 1, a support plate 2, a packaging box 3, a pusher plate 19, and a horizontal pushing component. The support plate 2 is fixedly installed on the side of the bag making machine body 1. Two packaging boxes 3 are slidably installed on the top of the support plate 2. Four pusher plates 19 are provided, with each pair of pusher plates 19 forming a group. The two groups of pusher plates 19 are respectively set in two packaging boxes 3 through two pusher components. The horizontal pushing component is set on the support plate 2.

[0024] like Figure 5As shown, during the production of packaging bags, two layers of rolled plastic film are first installed on two unwinding frames of the machine. The film rolls are kept under stable tension by a tension control system. The two layers of film are adjusted in position by guide rollers and a correction device to ensure that the films on both sides are aligned. Then, the double-layer film is conveyed to the heat sealing mechanism. Through the synchronous transmission of the feeding rollers, the heat-sealing edge is accurately positioned. After heat sealing, the film is cooled down quickly by cooling rollers to fix and shape the heat-sealed edge. Finally, it is cut into several packaging bags by a cutting blade and then pushed out.

[0025] like Figure 2 As shown, after the packaging bag is pushed out, one of the full-packing boxes 3 is located at the feeding port, and the packaging bag falls directly into the full-packing box 3. After it is full, the alignment component can drive the alignment plates 19 on both sides of the packaging bag to move, thereby aligning the packaging bag. The alignment component includes an electric cylinder 4, a connecting rod 5, a moving rack 6, a rotating shaft 7, a rotating gear 8, and a transmission component. The electric cylinder 4 is installed on one side of the full-packing box 3, and the output end of the electric cylinder 4 is fixedly connected to the side of one of the alignment plates 19 in one group. The top of each set of alignment plates 19 is fixedly installed with a connecting rod 5, and the side of the connecting rod 5 is fixedly installed with a moving rack 6. Two rotating shafts 7 are rotatably mounted on the side of the assembly box 3 via a mounting plate. Rotating gears 8 are fixedly mounted on the rotating shafts 7, and the two rotating gears 8 mesh with two moving racks 6 respectively. The transmission assembly is located on the side of the assembly box 3. The transmission assembly includes a mounting frame 9, a drive shaft 10, a drive gear 11, and a drive gear ring 12. The mounting frame 9 is fixedly mounted on the side of the assembly box 3. The drive shaft 10 is rotatably mounted on the mounting frame 9. Drive gears 11 are fixedly mounted on both ends of the drive shaft 10. Drive gears 11 are fixedly mounted on the rotating shaft 7, and the two drive gears 11 mesh with two drive gear rings 12 respectively.

[0026] Specifically, one of the electric cylinders 4 is activated, which drives one of the alignment plates 19 to move forward and contact one side of the packaging bag. Then, one of the alignment plates 19 drives the connecting rod 5 and the moving rack 6 to move forward. One of the moving racks 6 drives one of the rotating gears 8 to rotate. The rotating gear 8 drives one of the rotating shafts 7 to rotate. The rotating shaft 7 drives the drive gear ring 12 to rotate. The drive gear ring 12 drives one of the drive gears 11 to rotate, which in turn drives the drive shaft 10 to rotate. The drive shaft 10 then drives the drive gear ring 12 and the drive gear 11 at the other end to rotate, which in turn causes the other rotating shaft 7 to rotate. Simultaneously, the rotating gear ring drives the moving rack 6, which meshes with it, to move. Driven by the connecting rod 5, the other alignment plate 19 moves forward. Because the length of the alignment plate 19 is consistent with the internal length of the packaging box 3, the two alignment plates 19 move relative to each other within the packaging box 3, thereby pushing the sides of the packaging bag to align several misaligned packaging bags. When the worker takes them out, they can push them forward slightly to press against the inner wall of the packaging box 3, aligning their front and back positions before taking them out.

[0027] like Figure 3 , Figure 4 and Figure 6 As shown, before removing the packaging bag from one of the packaging boxes 3, the other packaging box 3 can be moved to the discharge port by a horizontal pushing component. The horizontal pushing component includes a support cover 13, a reciprocating screw 14, a motor 16, and a pushing frame 17. The support cover 13 is fixedly installed on the support plate 2. The reciprocating screw 14 is rotatably installed inside the support cover 13, and a matching crescent slider 15 is installed on the reciprocating screw 14. The motor 16 is installed on the side of the support cover 13, and the output end of the motor 16 is coaxially connected to the reciprocating screw 14. Push frames 17 are fixedly installed on both sides of the crescent slider 15, and the two push frames 17 are fixedly connected to two mounting frames 9 respectively.

[0028] Specifically, the motor 16 is started, and its output drives the reciprocating screw 14 to rotate within the support cover 13. Because the inner bottom wall of the support cover 13 has a groove, a limit block is slidably installed within the groove, and the top of the limit block is fixedly connected to the bottom of the crescent-shaped slider 15. Therefore, the crescent-shaped slider 15 can move on the reciprocating screw 14. It should be noted that the shape of the crescent-shaped slider 15 matches the helical groove of the reciprocating screw 14. When the reciprocating screw 14 rotates, the sidewall of the helical groove generates an axial thrust on the crescent-shaped slider 15 embedded within it. The crescent-shaped slider 15 can move along the axial trajectory of the reciprocating screw 14, thus moving left and right. When the crescent-shaped slider 15 reaches the end of the reciprocating screw 14, the crescent-shaped slider 15... 5 will smoothly transition to the reverse spiral groove, thereby achieving reciprocating movement. This is a well-known technology and will not be elaborated further. Furthermore, the top of the support plate 2 is provided with a sliding groove, and both packaging boxes 3 are slidably mounted on the support plate 2. The crescent slider 15 drives the two pushers 17 to move, thereby driving the two mounting frames 9 and the packaging boxes 3 to move synchronously. Since positioning rods 18 are fixedly installed on both sides of the support plate 2, when the side of one packaging box 3 contacts the side of one positioning rod 18, the other packaging box 3 is located at the discharge port. Similarly, when the side of another packaging box 3 contacts another positioning rod 18, the other packaging box 3 is located at the discharge port. This ensures that the collection of packaging bags is not delayed and that the staff can pick up the packaging bags.

[0029] Working principle: When retrieving the finished packaging bag from the packaging box 3, one of the electric cylinders 4 is activated first. The electric cylinder 4 drives one of the push plates 19 to move forward and contact one side of the packaging bag. Then, one of the push plates 19 drives the connecting rod 5 and the moving rack 6 to move forward. One of the moving racks 6 drives one of the rotating gears 8 to rotate. The rotating gear 8 drives one of the rotating shafts 7 to rotate. The rotating shaft 7 drives the drive gear ring 12 to rotate. The drive gear ring 12 drives one of the drive gears 11 to rotate, which in turn drives the drive shaft. When the drive shaft 10 rotates, it drives the drive gear ring 12 and drive gear 11 at the other end to rotate, which in turn causes another rotating shaft 7 to rotate. This synchronously drives the rotating gear ring to move the moving rack 6 that meshes with it. Under the drive of the connecting rod 5, it drives another pusher plate 19 to move forward. The two pusher plates 19 move relative to each other within a packaging box 3, thereby pushing the sides of the packaging bag to make several misaligned packaging bags neat. When the staff takes them out, they can push them forward to press against the inner wall of the packaging box 3, making their front and back positions neat as well, and then take them out.

[0030] Then, the motor 16 is started. The output end of the motor 16 drives the reciprocating screw 14 to rotate inside the support cover 13. The crescent slider 15 drives the two push frames 17 to move, thereby driving the two mounting frames 9 and the packaging box 3 to move synchronously. The packaging box 3 without packaging bags is moved into the feeding port for collection. Then, the staff takes out the packaging bags from the packaging box 3 that is full of packaging bags.
