Technical Field
[0001] This utility model belongs to the field of yarn labeling, and in particular relates to a loop yarn labeling machine. Background Technology
[0002] Bottle caps are extremely common packaging materials in daily life and industrial production. They are mainly used for sealing bottled products such as food and medicine, chemical raw materials, alcoholic beverages, and daily necessities, serving to seal the bottle and protect the product, while also having a certain aesthetic effect. Looped yarn needs to be labeled before being packed into boxes.
[0003] Existing loop yarn labeling machines lack the necessary pre-compression device during label roll transport, making the yarn prone to shifting during labeling and affecting the labeling effect. Furthermore, existing equipment has limitations in adapting to labeling requirements for different yarn specifications. Utility Model Content
[0004] In view of the above problems, the purpose of this utility model is to provide a loop yarn labeling machine, which aims to solve the problem of poor labeling effect of existing loop yarn labeling machines.
[0005] The present invention adopts the following technical solution:
[0006] The yarn labeling machine includes a worktable with a vertical plate. The vertical plate is sequentially equipped with an unwinding roller, a rolling roller, a guide roller, a pre-pressing assembly, a sliding plate that can move back and forth, and a take-up roller. A label-tearing plate is mounted on the sliding plate. A labeling assembly and a fixing roller are respectively positioned above and below the label-tearing plate on the vertical plate. A rotating wheel is located at the tail of the label-tearing plate on the sliding plate. A take-up motor for driving the take-up roller is mounted on the vertical plate. The pre-pressing assembly includes a limiting seat mounted on the vertical plate. A lower pressure roller is rotatably mounted on the vertical plate. An adjusting block and a connecting seat are rotatably mounted above and below the limiting seat. An upper pressure roller is rotatably mounted on the connecting seat facing the lower pressure roller. A pre-pressing screw is screwed into the connecting seat facing upwards, and the end of the pre-pressing screw is rotatably mounted in the adjusting block. A lower pressure cylinder is mounted on the vertical plate facing the limiting seat, and a pressure plate is mounted on the drive shaft of the lower pressure cylinder.
[0007] Furthermore, the labeling assembly includes a vertical plate mounted on a vertical plate, a sliding plate on the vertical plate, a connecting seat at the bottom of the sliding plate, a labeling seat below the connecting seat, a pair of adsorption seats at the bottom of the labeling seat, an air cavity formed inside the labeling seat, a row of suction holes on the adsorption seats, and the air cavity communicating with each suction hole, a vacuum connector communicating with the air cavity inside the labeling seat, and a lifting cylinder for driving the sliding plate to slide up and down on the vertical plate.
[0008] Furthermore, a fixing plate is rotatably provided on the upright plate, and a pressing wheel is rotatably provided on the fixing plate toward the rolling wheel. A screw sleeve is provided inside the fixing plate, and a screw is screwed into the screw sleeve. A tension spring is provided at the bottom of the screw, and the other end of the tension spring is installed at the corresponding position on the upright plate.
[0009] Furthermore, the inner end of the rolling wheel has a clearance notch, and the upper end of the fixing plate is located within the clearance notch.
[0010] Furthermore, the workbench is provided with an adjustment frame, the upright plate is slidably mounted on the adjustment frame via a slide block, the slide block contains a threaded sleeve, the adjustment frame is rotatably provided with a lead screw, and the lead screw is located inside the threaded sleeve, the top of the lead screw is provided with an adjustment handle.
[0011] The beneficial effects of this utility model are as follows: When the bottle cap is conveyed to the labeling position of the labeling machine, the winding motor drives the winding wheel to rotate. During the winding process, the labeling roll passes through the tearing plate. Under the action of the tearing plate, the label on the label roll gradually separates from the roll. After the labeling component adsorbs the label, the slide plate slides backward a short distance to form an avoidance zone. The labeling component directly and tightly affixes the label to the bottle cap. Finally, the labeling component resets, and the slide plate slides forward to the starting position, waiting to affix the next label to the next bottle cap.
[0012] In addition, after the labeling roll passes through the pre-pressing assembly, the gap between the upper and lower pressure rollers can be adjusted by turning the pre-pressing screw, thereby achieving pre-pressing of the labeling roll and making the labeling roll more stable during transmission. At the same time, the lower pressure cylinder drives the pressure plate to move downward until the pressure plate contacts the labeling roll. In this state, the pressure plate does not press the labeling roll tightly, but plays the role of limiting the upper and lower position of the labeling roll. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.
[0020] To illustrate the technical solution described in this utility model, specific embodiments are described below.
[0021] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.
[0022] Combination Figure 1-4 As shown, the yarn labeling machine includes a worktable 1, on which a vertical plate 2 is provided. The vertical plate 2 is sequentially provided with an unwinding roller 3, a rolling roller 4, a guide roller 5, a pre-compression assembly, a sliding plate 6 that can move back and forth, and a take-up roller 7. The unwinding roller, rolling roller, guide roller, and take-up roller are all rotatably mounted. The slide plate 6 is provided with a label-tearing plate 8. The upright plate 2 is provided with a label-applying component and a fixing wheel 9 at the upper and lower positions of the label-tearing plate 8, respectively. The slide plate 6 is provided with a rotating wheel 10 at the tail of the label-tearing plate 8. The upright plate 1 is provided with a winding motor 11 for driving the winding wheel 7 to rotate. The pre-pressing component includes a limiting seat 12 installed on the upright plate 1. The upright plate 1 is also rotatably provided with a lower pressure wheel 13. The limiting seat 12 is provided with an adjusting block 14 and a connecting seat 15 at the upper and lower positions, respectively. The connecting seat 15 is provided with an upper pressure wheel 16 rotatably facing the lower pressure wheel 13. The connecting seat 15 is screwed upward with a pre-pressing screw 17. The end of the pre-pressing screw 7 is rotatably installed in the adjusting block 14. The upright plate 1 is provided with a lower pressure cylinder 18 facing the limiting seat. The drive shaft of the lower pressure cylinder 18 is provided with a pressure plate 20.
[0023] In practice, the labeling machine is positioned directly opposite the conveyor table. Before labeling the bottle caps, the labeling roll needs to be installed on the unwinding roller as required. Then, the front end of the labeling roll is sequentially passed through the rolling roller, guide roller, pre-compression assembly, rotating roller, label tearing plate, and fixing roller, and finally installed on the take-up roller.
[0024] Once the bottle cap is conveyed to the labeling position of the labeling machine, the take-up motor drives the take-up rollers to rotate. During the take-up process, the label roll passes through the tear-off plate. Under the action of the tear-off plate, the label on the label roll gradually separates from the roll. After the labeling component picks up the label, the slide plate slides backward a short distance to create a clearance zone. The labeling component directly affixes the label tightly to the bottle cap. Finally, the labeling component resets, and the slide plate slides forward to the starting position, waiting to affix the next label to the next bottle cap. Figure 2 In the middle, the upright plate 1 is also provided with a push cylinder 21, which is used to push the slide plate 6 to slide back and forth.
[0025] The pre-compression assembly includes a limiting seat, within which an adjusting block and a connecting seat are rotatably mounted at their upper and lower positions, respectively. An upper pressure roller is rotatably mounted on the connecting seat, with the upper pressure roller facing the lower pressure roller. When the front end of the labeling roll passes through the pre-compression assembly, that is, the front end of the labeling roll first passes around the lower pressure roller, then through the gap between the upper and lower pressure rollers, the front end of the labeling roll passes the top surface of the limiting seat, and finally passes sequentially through the rotating roller, the label-tearing plate, the fixing roller, and finally is mounted on the winding roller.
[0026] After the labeling roll passes through the pre-pressing assembly, the gap between the upper and lower pressure rollers can be adjusted by turning the pre-pressing screw, thereby achieving pre-pressing of the labeling roll and making it more stable during transmission. Simultaneously, the lower pressure cylinder drives the pressure plate downwards until it contacts the labeling roll. In this state, the pressure plate does not press the labeling roll tightly; it serves to limit the upper and lower movement of the labeling roll.
[0027] also, Figure 2 In this design, both the top surface of the limiting seat 12 and the label-tearing plate 8 are provided with a pair of limiting blocks 22, which together form a limiting range within which the label roll is located. By limiting the left and right sides of the label roll within the limiting range, the label roll is further stabilized during the label-tearing process.
[0028] Figure 1-2 as well as Figure 5-6 The labeling assembly includes a vertical plate 23 mounted on a vertical plate 1. A sliding plate 24 is provided on the vertical plate 23. A connecting seat 25 is provided at the bottom of the sliding plate 24. A labeling seat 26 is provided below the connecting seat 25. A pair of suction seats 27 are provided at the bottom of the labeling seat 26. An air cavity 28 is formed inside the labeling seat 26. A row of suction holes 29 are opened on the suction seats 27, and the air cavity 28 communicates with each suction hole 29. A vacuum connector 30 communicating with the air cavity 28 is provided inside the labeling seat 26. A lifting cylinder 31 for driving the sliding plate 24 to slide up and down is also provided on the vertical plate 23.
[0029] When the label is applied to the bottle cap using the labeling assembly, the lifting cylinder first drives the sliding plate downwards until a pair of suction seats pick up the label detached from the label roll through the suction holes. Then, the sliding plate moves the label-tearing plate and rotating wheel backwards a short distance to avoid obstruction. Finally, the sliding plate continues to move downwards under the drive of the lifting cylinder until the suction seats firmly adhere the label to the bottle cap.
[0030] In the above structure, the air cavity is connected to an external air source through a true hole connector, thereby realizing the adsorption function of the label holder.
[0031] As a preferred structure, such as Figure 1-2 A fixing plate 32 is rotatably provided on the upright plate 1. A pressing wheel 33 is rotatably provided on the fixing plate 32 toward the rolling wheel 4. A screw sleeve 34 is provided inside the fixing plate 32. A screw 35 is screwed into the screw sleeve 34. A tension spring 36 is provided at the bottom of the screw 35. The other end of the tension spring 36 is installed at the corresponding position on the upright plate 1.
[0032] In the diagram, the inner end of the rolling wheel 4 has a clearance notch 41, which is used to avoid the fixing plate 32. When the upper end of the fixing plate is located within the clearance notch, the pressing wheel contacts the rolling wheel. After the labeling roll passes through the gap between the rolling wheel and the pressing wheel, the pressing wheel presses down on the labeling roll under the action of the tension spring. In practice, the degree of pressure of the pressing wheel on the labeling roll can be changed by adjusting the adjusting screw.
[0033] In this device, such as Figure 3 The workbench 1 is provided with an adjustment frame 37. The upright plate 1 is slidably mounted on the adjustment frame 37 via a slide block 38. A threaded sleeve is inside the slide block 38. A lead screw 39 is rotatably mounted on the adjustment frame 37, and the lead screw 39 is located inside the threaded sleeve (not shown in the figure). An adjustment handle 40 is provided at the top of the lead screw.
[0034] This device allows the lead screw to rotate within the yarn sleeve by rotating the adjustment handle, thereby moving the upright plate up and down on the adjustment frame. This adjusts the overall height of the device to accommodate yarn loops of different specifications.
[0035] 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.
