Description

Technical Field

[0001] This application relates to the technical field of labeling packaging bags, and more particularly to a multi-degree-of-freedom adjustable packaging bag labeling device. Background Technology

[0002] A packaging bag labeling device is a specialized piece of equipment used to automatically or semi-automatically affix labels to the surface of packaging bags. It typically consists of a label conveying mechanism, a peeling mechanism, a labeling head, and a positioning system, and is widely used in packaging production lines in the food, pharmaceutical, and electronics industries.

[0003] However, existing traditional labeling devices have significant limitations: their labeling heads are fixed in position and can only be used to apply labels in a single direction, making it impossible to adjust them with multiple degrees of freedom according to the actual size of the packaging bag or the label application requirements. Specifically, when the size of the packaging bag changes or when precise labeling is required in different areas (such as the front, side, or specific marking areas), traditional devices are prone to problems such as label misalignment, missing labels, or poor adhesion due to their lack of flexible position adjustment capabilities.

[0004] Therefore, there is an urgent need for a multi-degree-of-freedom adjustable packaging bag labeling device to solve the above problems.

[0043] Please refer to Figure 1 , Figure 2 In one embodiment, a multi-degree-of-freedom adjustable packaging bag labeling device includes a profile frame 1, on which two parallel slide rails 2 are provided along the packaging bag conveying direction, and a longitudinal moving component 3 perpendicular to the packaging bag conveying direction is slidably arranged in the slide rails 2.

[0044] A guide seat 4 is slidably mounted on the longitudinal moving component 3. A mounting plate 5 is mounted on the guide seat 4. Several adjustment slots 6 are provided on the mounting plate 5. The adjustment slots 6 are aligned with several screw holes on the guide seat 4. By adjusting the relative positions of the adjustment slots 6 and the screw holes, the relative position between the mounting plate 5 and the guide seat 4 can be adjusted.

[0045] A support plate 7 is provided below the mounting plate 5. A labeling mechanism 8 is provided on the support plate 7. A feeding component 9 is provided on one side of the support plate 7 and the feeding component 9 is used to supply labels to the labeling mechanism 8.

[0046] It is understood that the remote control packaging bag labeling device of this application is connected to a control box 10. The control box 10 is equipped with an operation panel, a display screen, and a three-color alarm light. The operation panel is used for parameter input and control such as switching and emergency stop. The display screen is used for real-time monitoring of the labeling status (such as the remaining amount of labels, the equipment running speed, fault prompts, etc.). The three-color alarm light (green / yellow / red) is used to reflect the equipment status (normal operation / standby / fault), which makes it easy for operators to quickly identify problems from a distance and reduce downtime for troubleshooting. The control box 10 is used to control the operation of each component in the labeling device and the coordination between each component.

[0047] Preferably, in this embodiment, the mounting plate 5 has a mounting hole, the guide seat 4 has a protrusion, the mounting hole is connected to the protrusion, and the mounting plate 5 can rotate relative to the protrusion through the mounting hole.

[0048] It is understandable that the vertical position of the labeling mechanism 8 is generally not much different. It can be finely adjusted according to the thickness of the product. By rotating the adjustment slot 6 on the mounting plate 5 by a certain angle and then locking it with screws or other means, the vertical position of the labeling mechanism 8 can be adjusted appropriately, thereby achieving fine adjustment in the vertical direction.

[0049] Furthermore, this application achieves lateral adjustment of the labeling component by moving the longitudinal moving component 3 via the slide rail 2; longitudinal adjustment of the labeling component by moving the mounting plate 5; and horizontal adjustment of the labeling component by adjusting the relative position of the adjusting slot 6 and the screw hole. Through the above multi-directional adjustment methods, the adaptability and accuracy of the labeling process are significantly improved, enabling the labeling component to label packaging bags of different sizes and to achieve accurate labeling in different areas of the packaging bag. Compared with traditional single-direction labeling machines, the overall application range is wider.

[0050] Specifically, please refer to Figure 1 , Figure 3Based on the above embodiments, the longitudinal moving component 3 includes a mounting base 31, a guide rod 32, a lead screw 33, and an operating handle 34. The slide rail 2 is provided with a mounting base 31, and the two mounting bases 31 are connected by two guide rods 32, and the two guide rods 32 pass through the mounting base 31.

[0051] A lead screw 33 is provided between the two guide rods 32, and one end of the lead screw 33 passes through the guide seat 4 and is rotatably connected to one of the mounting seats 31. The other end of the lead screw 33 passes through the other mounting seat 31 and extends outward to be connected to the operating handle 34.

[0052] It is understood that the mounting base 31 has a threaded hole, which is connected to the slide rail 2 by inserting screws or bolts, so as to fix the longitudinal moving component 3 after the position is adjusted; the mounting base 31 is fixed to the slide rail 2, and two parallel guide rods 32 pass through the guide seat 4 to form a stable support, ensuring that there is no sway during the movement; the lead screw 33 located between the guide rods 32 is engaged with the guide seat 4 through the threaded pair. When the operating handle 34 is rotated, the lead screw 33 drives the guide seat 4 to move linearly along the guide rods 32, so as to realize the high-precision longitudinal position adjustment of the labeling mechanism 8.

[0053] Specifically, please refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 Based on the above embodiments, the feeding assembly 9 includes a mounting plate 91, a pressure plate 92, a fixing block 93, a tensioning block 94, and a handle screw 95;

[0054] The mounting plate 91 is connected to the support plate 7 via the fixing plate 14. The mounting plate 91 is provided with a feeding mandrel, and the pressure plate 92 is provided on the feeding mandrel. The pressure plate 92 is provided with at least two fixing blocks 93. The fixing blocks 93 are provided with handle screws 95. The end of the handle screws 95 near the pressure plate 92 is connected to a tension block 94, and the tension block 94 is slidably connected to the pressure plate 92.

[0055] Furthermore, the pressure plate 92 is composed of a large-diameter cylinder, a small-diameter cylinder, and a pressure plate. The large-diameter cylinder and the small-diameter cylinder are coaxially arranged, and a pressure plate is arranged between them. A fixing block 93 is located on the small-diameter cylinder. One end of a tensioning block 94 is disposed in and slidably connected to the fixing block 93, and the other end of the tensioning block 94 is slidably connected to the large-diameter cylinder. A pin hole is provided on the fixing block 93, and a rotating pin is disposed in the pin hole. When the handle screw 95 is tightened, the position... The tensioning block 94 at the fixed block 93 retracts inward, while the tensioning block 94 inside the large-diameter cylinder opens outward. Because the inner rings at both ends of the label tape are pressed by the large-diameter cylinder, the tensioning block 94 at the fixed block 93 opens and presses against the inner ring of the label roll. The tighter it is tightened, the greater the tension. The label tape is fixed by the tension of the tensioning block 94 inside the large-diameter cylinder. That is, the radial movement of the handle screw 95 drives the bidirectional movement of the tensioning block 94, thereby generating radial tension to press the inner ring of the label tape.

[0056] Understandably, by manually loosening the handle screw 95, the pressure plate 92 is removed from the feeding mandrel, the rolled label tape is installed on the feeding mandrel, and the rolled label tape is pushed towards the pressure plate 92 until the label tape is in close contact with the surface of the pressure plate 92. Then, the pressure plate 92 is reinstalled on the feeding mandrel, ensuring that the surface of the pressure plate 92 is in close contact with the label tape. The handle screw 95 is then tightened to complete the installation of the label tape.

[0057] Specifically, please refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 Based on the above embodiments, it also includes a buffer assembly 11, which includes a tensioning plate 111, a first limiting roller 112, a screw 113, and a tension spring 114;

[0058] A tensioning plate 111 is rotatably connected to the side of the fixed plate 14 away from the mounting plate 91. A first limiting roller 112 is provided at the end of the tensioning plate 111 away from the fixed plate 14. The tensioning plate 111 is connected to a screw 113 provided on the fixed plate 14 through a tension spring 114. The screw 113 can move relative to the fixed plate 14.

[0059] It is understandable that the constant tension control of the label tape is achieved through the linkage design of the tension plate 111 and the first limiting roller 112. When the motor 831 pulls the label tape, the tension causes the tension plate 111 to rotate around the fixed plate 14, which drives the first limiting roller 112 to move and stretch the tension spring 114. At this time, the tension spring 114 generates a reverse force to buffer the instantaneous impact. The screw 113 can adjust the preload of the tension spring 114 to adapt to label tapes of different materials.

[0060] Specifically, please refer to Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 Based on the above embodiments, the labeling mechanism 8 includes a second limiting roller 81, a tensioning assembly 82, a driving assembly 83, a label peeling plate 84, and a receiving rod 85;

[0061] The support plate 7 is provided with a plurality of second limiting rollers 81. A tensioning component 82 is provided on one side of the support plate 7 located on the plurality of second limiting rollers 81. A label peeling plate 84 is inclinedly provided on the support plate 7 on one side of the tensioning component 82. A receiving rod 85 is provided on the support plate 7 on the other side of the tensioning component 82. The tensioning component 82 and the receiving rod 85 are connected by a drive component 83.

[0062] Preferably, the tensioning assembly 82 includes a fixing frame 821, a fixing pressure roller 822, an eccentric pressure roller 823, a pressing handle 824, and a handle limiting block 825;

[0063] A fixed frame 821 is provided on the support plate 7. One end of the fixed pressing roller 822 is rotatably connected to the fixed frame 821. The other end of the fixed pressing roller 822 passes through the support plate 7 and is connected to the drive assembly 83. One end of the eccentric pressing roller 823 is connected to the support plate 7. The other end of the eccentric pressing roller 823 passes through the fixed frame 821 and extends outward to be connected to the pressing handle 824. A handle limit block 825 is provided on the fixed frame 821.

[0064] It is understood that the clamping handle 824 has a set screw hole and a threaded hole for locking and clamping. The eccentric shaft of the eccentric pressure roller 822 is connected to the clamping handle 824 and communicates with the set screw hole. When the clamping handle 824 is rotated to the position, the set screw is tightened to fix the eccentric shaft of the eccentric pressure roller 822 so that it cannot rotate. When it is necessary to loosen, the clamping handle 824 can be easily loosened by rotating it in the opposite direction, that is, clockwise rotation is to loosen and counterclockwise rotation is to clamp.

[0065] Preferably, the drive assembly 83 includes a motor 831, a first synchronous belt assembly 832, and a second synchronous belt assembly 833;

[0066] A motor 831 is provided on the support plate 7. One end of the first synchronous belt assembly 832 is connected to the output end of the motor 831, and the other end of the first synchronous belt assembly 832 is connected to the fixed pressing roller 822. One end of the second synchronous belt assembly 833 is coaxially connected to the fixed pressing roller 822, and the other end of the second synchronous belt assembly 833 is connected to the receiving rod 85.

[0067] In summary, in practical applications, the second limiting roller 81 guides the label tape to form a specific wrapping angle path. The tensioning component 82 adopts a combination structure of an eccentric pressure roller 823 and a knurled fixed pressure roller 822. When the clamping handle 824 is rotated, the eccentric shaft generates an adaptive clamping force through the cam effect, which can ensure that the label tape is not slipped while avoiding damage to the film material. The drive component 83 is driven by a motor 831 through a dual synchronous belt. The first synchronous belt drives the fixed pressure roller 822 to actively pull the label tape, and the second synchronous belt synchronously drives the take-up bar 85 to wind up the release paper. When the label tape passes the inclined peeling plate 84, under the synergistic effect of tension and plate angle, the label is accurately peeled off and pressed onto the designated position on the packaging bag. At the same time, the take-up bar 85 maintains a constant speed to ensure that the waste is neatly wound.

[0068] Specifically, please refer to Figure 1 , Figure 7 , Figure 9 Based on the above embodiments, a detection component 12 is also included. The detection component 12 is provided on the support plate 7 above the label stripping plate 84. The detection component 12 includes a support rod 121, a sliding block 122, an adjusting block 123, an optical fiber fixing block 124, and an optical fiber 125.

[0069] The support rod 121 is connected to the support plate 7. A sliding block 122 is provided on the support rod 121. A sliding groove is provided on the sliding block 122. An adjusting block 123 is connected to the sliding groove. An optical fiber fixing block 124 is provided on the adjusting block 123. An optical fiber 125 is provided on the optical fiber fixing block 124.

[0070] It is understood that the sliding block 122 can adjust the vertical position of the optical fiber 125 on the support rod 121, the adjusting block 123 can adjust the front and back position on the sliding groove on the sliding block 122, and the optical fiber fixing block 124 can move left and right on the adjusting block 123 by relying on the upper sliding groove. After the above adjustment, the adjusted position can be fixed by inserting bolts and nuts. Through the above adjustment methods, the optical fiber 125 can be aligned with the optical fiber 125 detection hole on the label paper tape.

[0071] Specifically, please refer to Figure 1 , Figure 4 Based on the above embodiments, a monitoring component 13 is also included. The monitoring component 13 includes a sensor bracket 131, a sensor fixing block 132, and a sensor 133. The sensor bracket 131 is provided on the fixing plate 14, the sensor fixing block 132 is provided on the sensor bracket 131, and the sensor 133 is provided on the sensor fixing block 132.

[0072] It is understood that sensor 133 can be an infrared sensor or a photoelectric sensor. Sensor 133 can be used to detect the remaining amount of the label and the tape feeding status. When the paper tape breaks or runs out, an alarm is triggered immediately.

[0073] In summary, it can be understood that the label tape in this application uses release paper labels. Before labeling, the operator loosens the handle screws, removes the pressure plate 92 as a whole, and installs the label tape onto the feeding mandrel in the form of a roll, ensuring it is tightly attached to the surface of the mounting plate 91. Then, the pressure plate 92 is installed, and the label tape is applied... Figure 2 Thread the film in the correct direction and wind the label tape onto the take-up bar 85 as many points as possible so that the take-up bar can collect the tape normally when the work starts;

[0074] The operating clamping handle 824 is rotated toward the handle limit block 825. The clamping handle 824 drives the eccentric film pressing roller 823 to move upward. Because the eccentric film pressing roller 823 has an eccentric structure, when rotating, the clamping handle 824 can press the label paper tape between the eccentric film pressing roller 823 and the fixed film pressing roller 822 after it is rotated into position. The surface of the fixed film pressing roller 822 is knurled to prevent slippage during rotation, and the surface of the eccentric film pressing roller 823 is made of rubber so that the paper tape can be easily and smoothly pulled during rotation.

[0075] After installing the label tape, align the optical fiber 125 with the optical fiber detection hole on the label tape. The sliding block 122 can adjust the vertical position of the optical fiber 125 on the support rod 121, and the adjusting block 123 can adjust the front and back position on the sliding groove on the sliding block 122. The optical fiber fixing block 124 can move left and right on the adjusting block 123 by relying on the sliding groove on it. After adjusting the position, the position can be fixed by inserting bolts and nuts. Through the above adjustment methods, the optical fiber can be aligned with the optical fiber detection hole on the label tape.

[0076] When the product detection fiber on the belt conveyor detects the packaging bag, the motor 831 starts working, driving the first synchronous belt assembly 832 and the second synchronous belt assembly 833 to move together. Under the drive of the motor 831, the fixed film pressing roller 822 and the take-up rod 85 move together. Because the fixed film pressing roller 822 and the eccentric film pressing roller 823 clamp the label paper strip, the label paper strip is pulled towards the take-up rod during rotation. Under the blade state in front of the label peeling plate 84, the label is automatically peeled off the label paper strip and pasted onto the packaging bag on the belt conveyor.

[0077] During the rotation of motor 831, the label tape is pulled by the traction force of motor 831. During the pulling process, the label tape on the feeding assembly 9 is also fed forward. The two first limit rollers 112 on the feeding assembly 9 play a guiding role to prevent the label tape from going out of place during the pulling process. One of the first limit rollers 112 is connected to the tension plate at the rear end of the fixed plate 14. The tension plate is connected to the tension spring 114 and the screw 113. Under the traction of motor 832, this first limit roller 112 will swing at an angle. Under the action of tension spring 114, it plays a buffering role. When motor 831 stops working, it returns to the initial state due to the action of tension spring 114. When the label tape is used up, the sensor 133 installed on the fixed plate 14 senses that there is no material, the equipment stops working and alarms, prompting the operator to replace the label tape. Through the above steps, the automatic feeding and automatic labeling of packaging bags are completed.
