Description

Technical Field

[0001] The utility model relates to a tape cartoning and packaging machine, in particular to a split tape cutting and pressing device for an automatic tape cartoning and packaging machine, belonging to the technical field of packaging equipment. Background Art

[0002] With the development of the times, online shopping is more and more popular among people. Before online shopping items are sent through logistics and express delivery, they need to be packaged and cartoned, and tape is required for cartoning. The traditional methods are mostly that people hold the tape and use full-circle winding for cartoning and cross-shaped full-circle winding for cartoning. The operation is troublesome and laborious, and the cartoning efficiency is low. Therefore, people have invented automatic tape cartoning equipment. However, such cartoning equipment usually only automatically cartons the upper and lower openings of the packaging box, and cannot achieve full-circle winding cartoning with the tape. Moreover, when cartoning, the tape may not be pasted tightly, which easily causes the items in the packaging box to fall out. Therefore, the applicant of this patent has applied for the Chinese utility model patent No. 202023173061.8, with the patent name of "Circular Wrapping Type Tape Cartoning and Packaging Machine", which consists of a tape full-circle winding and rotating device, a tape automatic cutting and releasing device, a platform bridging structure, a linkage type flat sliding tape fitting device for the bottom brush of the packaging box and a brush fixed-point telescopic limiting device. The tape automatic cutting and releasing device includes a fixed plate, which is fixed to the side wall of the inner ring of the annular bearing. A lever is arranged on one side of the fixed plate. Rod shafts are made on both sides of the lever. A first torsion spring is arranged on the rod shaft. One end of the first torsion spring contacts the lower end of the lever, and the other end of the first torsion spring contacts the fixed plate. A transverse rotating shaft passes through the rod shaft. The lever is rotationally matched with the rotating shaft, and the rotating shaft is fixedly connected to the fixed plate. A blade is arranged on the side wall of one end of the lever. A guiding head is made at the other end of the lever. The guiding head passes through the fixed plate. A fixed bearing is arranged on the other side of the fixed plate. A gear is arranged on the outer ring of the fixed bearing. A cam is made on the side wall of the gear. The cam is matched with the guiding head. A first half tooth and a second half tooth are arranged on the annular turntable or the rotating plate. The rotating plate drives the first half tooth and the second half tooth to be respectively meshed with the gear. The lever and the blade are assembled together. When the annular turntable drives the tape to cover the packaging box in a full circle, the cam cooperates with the guiding head to drive the lever and the blade to close simultaneously. The tape is cut by the blade, and at the same time, the cut tape head is pressed under the connecting bridge by the lever. However, the disadvantage of this structure is that the tape and the cut tape head move synchronously, which easily causes the tape roll and the tape head to quickly pass through the lever under the inertia drive of the annular turntable after the tape is cut. The lever is prone to not being able to press the tape head in time, that is, the tape head is prone to slipping, thus affecting the next tape cartoning and packaging action. Summary of the Invention

[0003] The purpose of the present utility model is to overcome the deficiencies of the prior art and provide a split tape cutting and pressing device for an automatic tape sealing and packaging machine, in which the tape can be smoothly clamped and the overall operation is more reliable.

A turntable is arranged on the front side of the fixed frame, and a tape fixing ring is arranged on the turntable. The turntable is driven by power to rotate. A connecting seat is arranged on the front of the fixed frame inside the turntable. One end of the connecting seat is fixed to the fixed frame. A through hole is opened in the fixed frame below the connecting seat. A first lever and a second lever are arranged in the through hole. The tape is clamped between the first lever and the connecting seat. A blade is arranged on one side of the second lever, and the blade cooperates with the tape. A rod shaft is inserted into the first lever and the second lever, and the rod shaft is fixedly connected to the fixed frame. The first lever and the second lever are respectively rotationally matched with the rod shaft. The first lever and the second lever are respectively driven by a rotation control device to rotate downward to open or rotate upward to reset.

[0005] Further, the rotation control device includes a cam, and the cam is driven by power to rotate.

[0013] The utility model relates to a split-type adhesive tape cutting and pressing device for an automatic adhesive tape sealing and packaging machine, as Figure 1 — Figure 5 shown, which includes a fixing frame 1. A turntable 11 is arranged on the front side of the fixing frame 1. An adhesive tape fixing ring 12 is arranged on the turntable 11. The turntable 11 is driven by power to rotate. A connecting seat 31 is arranged on the front surface of the fixing frame 1 inside the turntable 11. One end of the connecting seat 31 is fixed to the fixing frame 1. A through hole 32 is opened in the fixing frame 1 below the connecting seat 31. A first lever 33 and a second lever 34 are arranged in the through hole 32. An adhesive tape is clamped between the first lever 33 and the connecting seat 31. A blade 341 is arranged on one side of the second lever 34. The blade 341 cooperates with the adhesive tape. A rod shaft 35 is inserted into the first lever 33 and the second lever 34. The rod shaft 35 is fixedly connected to the fixing frame 1. The first lever 33 and the second lever 34 are respectively rotationally matched with the rod shaft 35. The first lever 33 and the second lever 34 are respectively driven by a rotation control device to rotate downward to open or rotate upward to reset.

[0014] Further, the rotation control device includes a cam 14. The cam 14 is driven by power to rotate. A first guiding head 331 is arranged at the other end of the first lever 33. A second guiding head 342 is arranged at the other end of the second lever 34. The first guiding head 331 and the second guiding head 342 respectively cooperate with the cam 14. A first torsion spring 351 that provides an upward elastic restoring force to the first lever 33, and a second torsion spring 352 that provides an upward elastic restoring force to the second lever 34 are arranged on the rod shaft 35.

[0015] Further, a connecting rod 311 is arranged on the connecting seat 31. A rotating ring 312 is sleeved on the outer wall of the connecting rod 311. With the rotating ring 312, when the adhesive tape bypasses this position, it can prevent the adhesive tape from sticking to its surface, resulting in the inability to perform the subsequent action of brushing the adhesive tape head at the bottom of the packaging box flat.

[0016] The utility model discloses a split tape cutting and pressing device for an automatic tape sealing and packaging machine. When in use, first, the tape roll is sleeved on the tape fixing ring 12, and the adhesive tape head of the tape roll is pulled out (the adhesive side of the tape should face upward and the smooth side should face downward). Then, the first lever 33 is opened by hand, and the tape head is placed between the first lever 33 and the connecting seat 31. Under the action of the restoring force of the first torsion spring 351, the first lever 33 is driven to clamp the tape head upward. Then, people place the packaging box on the platform bridging structure 102 (the specific structure of the platform bridging structure 102 is prior art, which is used to place the packaging box, and there is a gap in the middle of the platform bridging structure 102 for the tape to bypass). The turntable 11 is driven to rotate by power (teeth can be made on the outer ring of the turntable 11, and the inner ring of the annular bearing is arranged on the inner ring of the turntable 11. The gear is driven by the motor, and the gear meshes with the teeth of the turntable 11 to drive the turntable 11 to rotate around the inner ring of the annular bearing). The turntable 11 drives the tape fixing ring 12 and the tape roll to rotate, so that the tape first adheres to the left side wall of the packaging box, and the tape covers the upper end and the left lower end surface of the packaging box (but not yet adhered). At the same time, the cam 14 is driven to rotate by power (the cam 14 can be directly driven to rotate by the motor 13, or the cam 14 can be driven to rotate by the original motor driving the turntable 11 through a linkage structure). The convex arc periphery of the cam 14 gradually contacts the first guiding head 331 and the second guiding head 342. Under the guiding action of the convex arc periphery of the cam 14, the first guiding head 331 and the second guiding head 342 are driven to rotate upward. The first guiding head 331 drives the first lever 33 to open downward through the rod shaft 35, and the first lever 33 releases the tape head. The second guiding head 342 drives the second lever 34 to open downward through the rod shaft 35, and the second lever 34 drives the blade 341 to open downward. At this time, the tape fitting device 103 (the specific structure of the tape fitting device 103 is prior art, which brushes and fits the tape at the bottom of the packaging box by moving the brush left and right) performs the first brushing and fitting on the tape head at the bottom of the packaging box. The turntable 11 continues to drive the tape fixing ring 12 and the tape roll to rotate, so that the tape adheres to the right side wall of the packaging box, and the tape covers the right lower end surface of the packaging box (but not yet adhered). At this time, the power also drives the cam 14 to rotate to the highest point of the convex arc periphery (vertical surfaces 141 are arranged at the highest and lowest points of the convex arc periphery of the cam 14) to contact the first guiding head 331 and the second guiding head 342. First, the first guiding head 331 cooperates with the vertical surface 141. Under the action of the restoring force of the first torsion spring 351, the first guiding head 331 is driven to quickly reset downward through the vertical surface 141. The first guiding head 331 drives the first lever 33 to clamp the tape upward around the rod shaft 35. Then, the second guiding head 342 cooperates with the vertical surface 141. Under the action of the restoring force of the second torsion spring 352, the second guiding head 342 is driven to quickly reset downward through the vertical surface 141. The second guiding head 342 drives the second lever 34 to rotate upward around the rod shaft 35,The second lever 34 drives the blade 341 to move upward to cut the tape at the bottom of the packing box. After cutting, the tape head of the tape roll is pressed between the first lever 33 and the connecting seat 31, and the next case sealing and packaging can be carried out. After cutting, the tape tail at the bottom of the packing box is flattened and adhered again through the tape adhering device 103, and the packing box is sealed. This is a split tape cutting and pressing device for an automatic tape sealing and packaging machine. By arranging two levers in the perforation 32 of the fixed frame 1, after the tape completely covers the whole circle of the packing box, the first lever 33 is reset first to clamp the tape, and the second lever 34 is reset later to cut the tape, avoiding the synchronous operation of tape cutting and clamping, which may cause the tape head after cutting to slip off, making the overall action more reliable and ensuring that the tape can be smoothly clamped.
