Description
Technical Field
[0001] The invention relates to the technical field of packaging wrapping machines, in particular to an adhesive tape machine with a positioning function for adjusting wrapping intervals. Background Art
[0002] Wrapping machines are widely used in the containerization of products such as foreign trade exports, food and beverages, plastic chemicals, glass and ceramics, and electromechanical castings. They can prevent damage to goods during transportation and play a role in dust and moisture prevention and cleaning. Due to the different sizes and types of goods, they are usually packaged and transported manually. However, the quality of manual packaging varies and the production efficiency is low. The main work of the wrapping machine is to wrap the tape or film around the box through the rotation of the wrapping mechanism and the stepping transport box.
[0003] Among the existing wrapping machines, horizontal wrapping machines are widely used. They can spirally wrap tape film evenly on the surface of box-like objects, but the box itself is placed on a conveyor belt and needs to be manually corrected to prevent the box from being in a skewed state when entering the wrapping machine. This will cause the wrapped tape film to have uneven coverage and incomplete coverage. On the wrapping machine itself, the cutting device of most wrapping machines is only for one type of tape or film, and the toothed knife can only cut the tape but cannot effectively cut the film. Manual replacement of the tool will affect the working efficiency of the wrapping machine, and it is necessary to design a shearing mechanism with two tools that can switch between each other to adapt to the winding of tape or film at the same time. Summary of the invention
[0004] The purpose of the present invention is to provide a method to solve the problems raised in the above background technology.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A tape machine with a positioning function for adjusting the winding spacing includes a base frame, a first servo motor, a transmission belt, a resistor seat, a positioning transmission mechanism, a shearing and packaging mechanism, and a visual probe. The first servo motor, the resistor seat, the positioning transmission mechanism, and the shearing and packaging mechanism are all fixedly connected to the base frame, the output end of the first servo motor is transmission-connected to the positioning transmission mechanism, the positioning transmission mechanism is provided with several groups, adjacent positioning transmission mechanisms are transmission-connected by a transmission belt, the shearing and packaging mechanism is connected to the resistor seat by electrical signals, the positioning transmission mechanism is connected to the visual probe by electrical signals, and the visual probe is fixedly connected to the shearing and packaging mechanism.
[0006] The tape machine is used for packaging and winding box-type articles, and is suitable for both tape and film. The box is placed on the positioning transmission mechanism, and the first servo motor outputs torque to drive the positioning transmission mechanism through the transmission belt. The box is transmitted on the positioning transmission mechanism, and the visual probe detects whether the box is horizontal on the positioning transmission mechanism, and sends an electrical signal to the positioning transmission mechanism. The positioning transmission mechanism receives the electrical signal and corrects the box, so that the box enters the shearing and packaging mechanism horizontally and vertically; the box acts on the positioning transmission mechanism through gravity, so that the resistance of the resistor seat changes, and sends an electrical signal to the shearing and packaging mechanism. The shearing and packaging mechanism starts to wind the tape or film on the box, and after the winding is completed, the tape or film is sheared and cut.
[0007] Furthermore, the positioning transmission mechanism includes a main shaft, a first transmission seat, a second transmission seat, a secondary shaft, a first pulley seat, a positioning sensing mechanism, a torque adjustment mechanism, a third transmission seat, and a second pulley seat. The main shaft is transmission-connected to the output end of the first servo motor, the first transmission seat and the second transmission seat are both fixedly connected to the main shaft, the adjacent first transmission seats are transmission-connected via a transmission belt, the second transmission seat is connected to the secondary shaft via a belt transmission, the main shaft is transmission-connected to the first pulley seat, the secondary shaft is transmission-connected to the torque adjustment mechanism, the torque adjustment mechanism is transmission-connected to the third transmission seat via a belt transmission, the third transmission seat is transmission-connected to the second pulley seat, the first pulley seat, the positioning sensing mechanism, and the second pulley seat are all fixedly connected to the base frame, and the torque adjustment mechanism is connected to the visual probe via an electrical signal.
[0008] The first servo motor outputs torque through the main shaft, the second transmission seat, the secondary shaft, the torque adjustment mechanism, and the third transmission seat to drive the first pulley seat and the second pulley seat. The box is transported on the positioning transmission mechanism. The weight of the box itself presses the positioning sensing mechanism, and the corresponding position on the resistor seat is pressed by the positioning sensing mechanism to change the resistance of the resistor seat. The visual probe detects whether the box is horizontal on the positioning transmission mechanism and sends an electrical signal to the torque adjustment mechanism. The torque adjustment mechanism changes the output speed, so that there is a speed difference between the first pulley seat and the second pulley seat, so that the offset box can be corrected to a vertical shear packaging mechanism.
[0009] Furthermore, the positioning sensing mechanism includes a mounting frame, a first spring seat, a base, an electrode sheet, and a third pulley seat. The mounting frame is fixedly connected to the base frame, the first spring seat is fixedly connected to the mounting frame, the base is fixedly connected to the first spring seat, the base is slidably connected to the mounting frame, and the electrode sheet and the third pulley seat are both fixedly connected to the base.
[0010] The weight of the box itself presses down the third pulley seat, and the third pulley seat slides downward along the mounting frame. The electrode sheet installed on the base moves downward, so that the electrode sheet contacts the resistor seat, which can change the resistance of the resistor seat, thereby judging that the box is transported to the positioning transmission mechanism, and changing the electrical signal emitted by the resistor seat.
[0011] Furthermore, the torque adjustment mechanism includes an outer shell, a fixed ring, a pushing cylinder, a torque adjustment mechanism, a bevel gear set, and an opposite side transmission mechanism. The fixed ring, the pushing cylinder, the bevel gear set, and the opposite side transmission mechanism are all fixedly connected to the outer shell, the torque adjustment mechanism is connected to the secondary shaft, the opposite side transmission mechanism is connected to the third transmission seat through a belt drive, the output end of the pushing cylinder is fixedly connected to the torque adjustment mechanism, the torque adjustment mechanism is slidably connected to the fixed ring, the torque adjustment mechanism and the opposite side transmission mechanism are all connected to the bevel gear set, and the pushing cylinder visual probe is connected through an electrical signal.
[0012] The countershaft transmits torque to the torque regulating mechanism, and the visual probe detects whether the box is level and sends an electrical signal to the pushing cylinder. The pushing cylinder pushes the torque regulating mechanism, and the torque regulating mechanism slides along the fixed ring. The torque transmitted to the bevel gear set by the torque regulating mechanism changes, and the torque output to the third transmission seat through the opposite side transmission mechanism changes, so that there is a speed difference between the first pulley seat and the second pulley seat, which can correct the offset box.
[0013] Furthermore, the torque adjustment mechanism includes an inner bevel cylinder, a main rod, a second spring seat, an articulated seat ring, a first articulated rod, a pulley articulated seat, a second articulated rod, a hook-belt articulated seat, and a sliding plate. The inner bevel cylinder is slidably connected to the fixed ring, the main rod is transmission-connected to the secondary shaft, the second spring seat is fixedly connected to the main rod and the articulated seat ring, the articulated seat ring is slidably connected to the main rod, the articulated seat ring is articulated to the first articulated rod and the second articulated rod, the first articulated rod is articulated to the pulley articulated seat, the pulley articulated seat is slidably connected to the inner bevel cylinder, the hook-belt articulated seat is articulated to the second articulated rod, the sliding plate is fixedly connected to the main rod, a sliding groove is provided on the sliding plate, the hook-belt articulated seat is slidably connected to the sliding groove, and the hook-belt articulated seat is connected to the bevel gear group through a belt drive.
[0014] The pushing cylinder pulls the inner bevel cylinder to move toward the direction close to the fixed ring. Under the extrusion of the inner bevel of the inner bevel cylinder, the pulley articulated seat moves toward the direction close to the main rod. Through the articulation between the articulated seat ring, the first articulated rod and the pulley articulated seat, the articulated seat ring moves toward the direction close to the fixed ring. Through the articulation between the articulated seat ring, the second articulated rod and the hook-belt articulated seat, the hook-belt articulated seat moves along the slide groove toward the center of the sliding disk. The radius of the virtual circle formed by the hook-belt articulated seat is reduced, and the torque transmitted to the bevel gear set through the belt is reduced.
[0015] Furthermore, the shearing and packaging mechanism includes a base, a ring frame, a second servo motor, a rotating ring, and a double cutting knife mechanism. The base is fixedly connected to the base frame, the ring frame is fixedly connected to the base, the second servo motor visual probe is fixedly connected to the ring frame, the output end of the second servo motor is connected to the rotating ring through a belt drive, the rotating ring is rotatably connected to the ring frame, the double cutting knife mechanism is fixedly connected to the ring frame, and the second servo motor is connected to the resistor seat through an electrical signal.
[0016] When the box is transported to the ring frame, the second servo motor is started according to the electrical signal sent by the resistor seat, and the output torque is transmitted to the rotating ring through the belt. The rotating ring is installed with a tape roll or a film roll. The rotating ring rotates to drive the tape roll or the film roll to be wound around the box. The double cutter mechanism cuts the tape roll and cuts one third of the film roll. The remaining part is pulled away by the rotation of the rotating ring to separate it.
[0017] Furthermore, the double-cutter mechanism includes a horizontal frame, a cutting plate, a third servo motor, a workstation switching mechanism, a tape toothed knife, and a film knife. The horizontal frame is fixedly connected to the ring frame, the cutting plate and the third servo motor are fixedly connected to the horizontal frame, the output end of the third servo motor is fixedly connected to the workstation switching mechanism, and the tape toothed knife and the film knife are fixedly connected to the workstation switching mechanism.
[0018] The tape or film is assembled on the rotating ring, and one end of the tape or film is pulled out through the gap between the cutting plate and the station switching mechanism. The third servo motor outputs torque to the station switching mechanism according to the tape or film, and the station switching mechanism rotates. When cutting the tape, the tape tooth knife is turned to face the cutting plate, and the tape tooth knife is pushed through the station switching mechanism to cut the tape; when cutting the film, the film knife is turned to face the cutting plate.
[0019] Furthermore, the workstation switching mechanism includes an outer cylinder, a base plate, a fourth servo motor, a cross slide, a main gear, a first slide, a second slide, an articulated connecting rod, and a sub-gear. The outer cylinder is fixedly connected to the output end of the third servo motor, the base plate is fixedly connected to the outer cylinder, the fourth servo motor and the cross slide are both fixedly connected to the base plate, the output end of the fourth servo motor is transmission-connected to the main gear, the first slide and the second slide are both slidingly connected to the cross slide, the first slide and the second slide are both hinged to the articulated connecting rod, the sub-gear is rotatably connected to the articulated connecting rod, the main gear is meshed with the tooth surface of the sub-gear, the first slide is fixedly connected to the tape tooth knife, and the second slide is fixedly connected to the film knife.
[0020] When the workstation switching mechanism pushes the tape tooth knife and the film knife, the fourth servo motor outputs torque to the main gear, and transmits torque to the articulated connecting rod through the meshing of the tooth surfaces of the main gear and the sub-gear. Since the two ends of the articulated connecting rod are installed on the first slide and the second slide, the cross slide limits the freedom of the first slide and the second slide, so that the sub-gear rotates around the main gear in a planetary manner. At the same time, the first slide reciprocates horizontally along the cross slide to push out the tape tooth knife; the second slide reciprocates vertically along the cross slide to push out the film knife; the tape tooth knife and the film knife alternately reciprocate to push out the knife hole of the outer cylinder.
[0021] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention designs a positioning transmission mechanism, the third pulley seat is pressed by the weight of the box itself, the third pulley seat slides downward along the mounting frame, and the electrode sheet installed on the base is displaced downward, so that the electrode sheet contacts the resistor seat, and the resistance of the resistor seat can be changed, so as to judge whether the box is transported to the positioning transmission mechanism, so that the electrical signal emitted by the resistor seat is changed, and it can be judged whether the box is transported to the winding station, and the winding work can be carried out. Under the condition of the horizontal speed of the winding machine, the winding spacing of the tape can be regulated by adjusting the torque output by each group of positioning transmission mechanisms; the present invention designs a torque adjustment mechanism, the visual probe detects whether the box is transported horizontally, sends an electrical signal to the push cylinder, pulls the inner bevel cylinder to move, and under the extrusion of the inner bevel of the inner bevel cylinder, the hook belt articulated seat is displaced along the slide groove toward the center of the sliding disk, the radius of the virtual circle formed by the hook belt articulated seat is reduced, and the torque transmitted to the bevel gear set by the belt is reduced, so that the first pulley seat and the second There is a speed difference between the pulley seats, which can correct the offset box body, so that the box body can enter the shearing and packaging mechanism 6 horizontally and vertically, and the tape or film wrapped around the packaging box body can be fully covered and evenly; the present invention designs a double-cutter mechanism, and the station switching mechanism rotates. When cutting the tape, the tape tooth knife is turned to face the cutting plate, and the tape tooth knife is pushed to cut the tape through the station switching mechanism. When cutting the film, the film knife is turned to face the cutting plate, and the fourth servo motor outputs torque to the main gear, so that the sub-gear rotates around the main gear in a planetary manner. The first slide reciprocates horizontally along the cross slide, and the second slide reciprocates vertically along the cross slide. The tape tooth knife and the film knife alternately reciprocate to push out the knife hole of the outer cylinder, so that the shearing mechanism can be applied to both tape and film. When one set of cutters is working, the other set is hidden; the present invention can automatically load and unload materials, can fully cover and evenly wrap the surface of the box body, and can adapt to both tape and film winding materials at the same time, greatly improving the winding quality and packaging efficiency of the packaging wrapping machine.

The output end of the first servo motor 2 is transmission-connected to the positioning transmission mechanism 5. The positioning transmission mechanism 5 is provided with a plurality of groups. Adjacent positioning transmission mechanisms 5 are transmission-connected through the transmission belt 3. The shearing and packaging mechanism 6 is connected to the resistor seat 4 through electrical signals. The positioning transmission mechanism 5 is connected to the visual probe 7 through electrical signals. The visual probe 7 is fixedly connected to the shearing and packaging mechanism 6.
[0037] The tape machine is used for packaging and winding box-type articles, and is suitable for both tape and film. The box is placed on the positioning transmission mechanism 5, and the first servo motor 2 outputs torque to drive the positioning transmission mechanism 5 through the transmission belt 3. The box is transmitted on the positioning transmission mechanism 5. The visual probe 7 detects whether the box is horizontal on the positioning transmission mechanism 5, and sends an electrical signal to the positioning transmission mechanism 5. The positioning transmission mechanism 5 receives the electrical signal and corrects the box, so that the box enters the shearing and packaging mechanism 6 horizontally and vertically; the box acts on the positioning transmission mechanism 5 through gravity, so that the resistance of the resistor seat 4 changes, and sends an electrical signal to the shearing and packaging mechanism 6. The shearing and packaging mechanism 6 starts to wind the tape or film on the box. After the winding is completed, the tape or film is cut.

[0045] The pushing cylinder 573 pulls the inner bevel cylinder 5741 to move toward the direction close to the fixed ring 572. Under the extrusion of the inner bevel of the inner bevel cylinder 5741, the pulley articulated seat 5746 moves toward the direction close to the main rod 5742. Through the articulation between the articulated seat ring 5744, the first articulated rod 5745 and the pulley articulated seat 5746, the articulation seat ring 5744 moves toward the direction close to the fixed ring 572.

The outer cylinder 6541 is fixedly connected to the output end of the third servo motor 653, the bottom plate 6542 is fixedly connected to the outer cylinder 6541, the fourth servo motor 6543 and the cross slide 6544 are fixedly connected to the bottom plate 6542, and the fourth The output end of the servo motor 6543 is transmission connected to the main gear 6545, the first slide 6546 and the second slide 6547 are both slidingly connected to the cross slide rail 6544, the first slide 6546 and the second slide 6547 are both hinged to the hinged connecting rod 6548, the sub-gear 6549 is rotationally connected to the hinged connecting rod 6548, the main gear 6545 and the sub-gear 6549 tooth surfaces are meshed, the first slide 6546 is fixedly connected to the tape tooth knife 655, and the second slide 6547 is fixedly connected to the film knife 656.
[0051] When the workstation switching mechanism 654 pushes the tape sprocket 655 and the film knife 656, the fourth servo motor 6543 outputs torque to the main gear 6545, and the torque is transmitted to the hinged connecting rod 6548 through the meshing of the tooth surfaces of the main gear 6545 and the sub-gear 6549. Since both ends of the hinged connecting rod 6548 are installed on the first slide 6546 and the second slide 6547, the cross slide 6544 limits the freedom of the first slide 6546 and the second slide 6547, so that the sub-gear 6549 makes planetary rotation around the main gear 6545. At the same time, the first slide 6546 reciprocates horizontally along the cross slide 6544 to push out the tape sprocket 655; the second slide 6547 reciprocates vertically along the cross slide 6544 to push out the film knife 656; the tape sprocket 655 and the film knife 656 alternately reciprocate to push out the knife hole of the outer cylinder 6541.
[0052] Working principle of the present invention: the tape machine is used for packaging and winding box-type articles, which can be applied to both tape and film. The box is placed on the positioning transmission mechanism 5, and the first servo motor 2 outputs torque to drive the positioning transmission mechanism 5 through the transmission belt 3. The box is transmitted on the positioning transmission mechanism 5. The visual probe 7 detects whether the box is level on the positioning transmission mechanism 5, and sends an electrical signal to the push cylinder 573 to pull the inner bevel cylinder 5741 to move toward the direction close to the fixed ring 572. Under the extrusion of the inner bevel of the inner bevel cylinder 5741, the pulley articulated seat 5746 moves toward the direction close to the main rod 5742, so that the hook belt articulated seat 5748 moves along the slide groove 57491 toward the center of the sliding plate 5749, and the radius of the virtual circle formed by the hook belt articulated seat 5748 is reduced. The torque transmitted to the bevel gear set 575 by the belt is reduced, so that there is a speed difference between the first pulley seat 55 and the second pulley seat 59, which can be To correct the offset box; make the box enter the shearing and packaging mechanism 6 horizontally and vertically; the box acts on the positioning transmission mechanism 5 through gravity, so that the resistance of the resistor seat 4 changes, and an electrical signal is sent to the shearing and packaging mechanism 6. The tape or film is assembled on the rotating ring 64, and one end of the tape or film is pulled out through the gap between the cutting plate 652 and the station switching mechanism 654. The rotating ring 64 rotates to drive the tape roll or film roll to be wound on the box. When the station switching mechanism 654 pushes the tape tooth knife 655 and the film knife 656, the fourth servo motor 6543 outputs torque to the main gear 6545, so that the sub-gear 6549 rotates around the main gear 6545 to make planetary rotation. The first slide 6546 reciprocates horizontally along the cross slide 6544, and the second slide 6547 reciprocates vertically along the cross slide 6544. The tape tooth knife 655 and the film knife 656 are alternately reciprocated to push out the knife hole of the outer cylinder 6541 for cutting.
