Technical Field

[0001] This utility model relates to the field of label feeding equipment technology, and in particular to a semi-cutting feeder. Background Technology

[0002] With the development of automation technology, label feeders, as an important component of automatic labeling equipment, have been widely used in packaging, logistics, electronics, and other industries. Label feeders are mainly used to automatically peel labels off label rolls and supply them to downstream equipment, improving production efficiency and reducing manual operation. Currently, common label feeders on the market typically include basic components such as a feeding mechanism, a peeling mechanism, a pulling mechanism, and a receiving mechanism. For example, CN214002330U discloses a label feeder and labeling equipment, including a mounting frame, a feeding assembly, a tensioning assembly, a peeling assembly, a label receiving platform, a drive assembly, and a first receiving assembly. The distance between the tensioning assembly and the peeling assembly can be set to be greater than the length of the sheet material, allowing the tape tensioned between the tensioning and peeling assemblies to form an adhesive platform. This enables label peeling from both roll materials and sheet materials on a single label feeder.

[0003] However, existing label feeders have some shortcomings. First, most label feeders can only peel off labels and cannot cut them, resulting in label sizes that cannot be adjusted according to actual needs. Second, existing label feeders lack effective label cutting mechanisms during peeling and attaching, limiting the application scenarios of the labels, especially on production lines requiring different label sizes, often necessitating the replacement of different label rolls, increasing production costs and operational complexity. Furthermore, existing label feeders lack precise label positioning and cutting functions after peeling, making it difficult to meet the requirements of high-precision labeling. Utility Model Content

[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] Please see Figure 1 and Figure 2 This embodiment provides a semi-cutting feeder, which includes a base 10. The base 10 has a feeding shaft 20, a label peeling section 30, a pulling section 40, and a bottom paper receiving shaft 50 arranged sequentially around the free end of the label roll. A movable label receiving platform 60 is provided on the base 10 in front of the label peeling section 30. A label cutting section 70 is provided on the base 10 between the movable label receiving platform 60 and the label peeling section 30. A belt and motor drive mechanism 80 is provided on the base 10 to simultaneously drive the pulling section 40 and the bottom paper receiving shaft 50. The base 10 also has a control device 90 that controls the operation of the mechanism components on the feeder. The control device 90 has a touch screen display. During operation, the free end of the label roll is led out from the feeding shaft 20 and passes around the label peeling section. 30. The label is peeled off by the label peeling section 30. The peeled label passes through the label cutting section 70. The moving label receiving platform 60 moves towards the label peeling section 30. When the fiber optic sensor 65 detects the label, the moving label receiving platform 60 and the belt and motor drive mechanism 80 stop moving. At this time, the label cutting section 70 receives a signal and cuts the label. After cutting, the moving label receiving platform 60 moves away from the label peeling section 30 so that the external labeling unit can take the label for application. At this time, the label cutting section 70 resets, and the belt and motor drive mechanism 80 drives the material pulling section 40 and the bottom paper receiving shaft 50 to move simultaneously to pull and wind up the label bottom paper for the next label feeding and cutting.

[0024] Please see Figure 3 Specifically, in this embodiment, the label peeling part 30 is mainly used to peel the label from the backing paper. The label peeling part 30 includes a suction plate 31. One end of the suction plate 31 is connected to a peeling blade 32. The end face of the other end of the suction plate 31 is arc-shaped. The free end of the label roll passes through the arc-shaped surface of the suction plate 31 to transition to the upper surface of the suction plate 31, and after passing around the upper surface of the peeling blade 32, it bends down through the tip of the peeling blade 32 and passes through the pulling part 40.

[0025] Furthermore, to prevent the label from deviating from or lifting off the suction plate 31 during the label peeling process, suction holes 35 are evenly distributed on the upper surface of the suction plate 31, and a second suction groove is provided on the back of the suction plate 31, with the suction holes 35 communicating with the second suction groove. The second suction groove is covered by a second cover plate, and the second cover plate has a second air pipe connector communicating with the second suction groove. A guide groove 33 is provided on the upper surface of the suction plate 31, and adjustable baffle plates 34 are provided at both ends of the guide groove 33. By adjusting the spacing of the baffle plates 34, the guiding requirements of labels of different widths can be adapted to ensure that the label moves stably on the suction plate 31. At the same time, the second air pipe connector can be connected to a vacuum generator. When the suction device is working, the suction holes 35 generate an adsorption force through the second air pipe connector and the second suction groove, tightly adhering the label to the upper surface of the suction plate 31, effectively preventing the label from deviating from or lifting off the suction plate 31, and ensuring the stability and accuracy of the label peeling process.

[0026] Furthermore, the upper end of the peeling blade 32 is provided with a pressure guide plate 36, which is detachably mounted on the upper surface of the peeling blade 32 by bolts. A material passage groove is provided on the end face of the pressure guide plate 36 corresponding to the upper surface of the peeling blade 32. The free end of the label roll passes through the material passage groove. Through the guiding effect of the material passage groove, the label roll can pass more smoothly and steadily around the upper surface of the peeling blade 32, further ensuring the stability of the label peeling process. The pressure guide plate 36 ensures that the label roll passes smoothly through the peeling blade 32, preventing wrinkles or deviation of the label roll during the peeling process.

[0027] Please see Figure 4 The mobile label receiving platform 60 includes a horizontal support plate 61 and a telescopic cylinder 62 mounted on the horizontal support plate 61. The output end of the telescopic cylinder 62 has a label receiving vertical plate 63. A non-stick plate 64, perpendicular to the label receiving vertical plate 63, is mounted on the top of the label receiving vertical plate 63. The telescopic cylinder 62 drives the label receiving vertical plate 63, causing the non-stick plate 64 to move back and forth, thereby receiving and transporting labels. The non-stick plate 64 has protrusions 640 on both sides, each protrusion having multiple suction holes 641. A first suction groove is located on the back of the non-stick plate 64. The suction holes 641 on the two protrusions 640 communicate with the first suction groove, which has a first cover plate. The first cover plate has a first air pipe connector communicating with the first suction groove. An optical fiber sensor 65 passes through the first cover plate and the non-stick plate 64 sequentially. The two protrusions 640 have adjustable stop blocks 66.

[0028] When the mobile label receiving platform 60 is in operation, the telescopic cylinder 62 is activated, moving the label receiving vertical plate 63 and the non-stick plate 64 forward to a set position, ready to receive the labels cut from the label cutting section 70. At this time, the vacuum generator connected to the first air pipe connector operates, generating adsorption force through the first suction groove and adsorption hole 641, firmly adsorbing the label onto the non-stick plate 64. The fiber optic sensor 65 monitors the position and status of the label in real time, ensuring that the label is accurately placed on the non-stick plate 64. The stop block 66 serves to position and restrict the movement of the label, preventing the label from shifting during transport. After the non-stick plate 64 receives the label, the telescopic cylinder 62 is activated again, moving the label receiving vertical plate 63 and the non-stick plate 64 backward, moving the label away from the label peeling section 30, making it easier for the labeling unit to remove the label and perform the labeling operation. At the same time, the position of the stop block 66 can be adjusted according to actual needs to accommodate labels of different sizes and shapes.

[0029] Please see Figure 5 and Figure 6 The label cutting section 70 is used to cut labels. The label cutting section 70 includes a hollow frame 71. Inside the hollow frame 71, on the upper and lower sides, there are movable cutters 72 and fixed cutters 73 that clamp each other and cut the labels. The fixed cutter 73 is fixed to the hollow frame 71. The top of the hollow frame 71 is provided with a punching cylinder 74 whose output end is connected to the movable cutter 72. On both sides of the bottom of the fixed cutter 73, there are L-shaped limiting blocks 75 fixed to the hollow frame 71. The top of the L-shaped limiting blocks 75 contacts the bottom surface of the fixed cutter 73. The punching cylinder 74 drives the movable cutter 72 to move downward, so that the movable cutter 72 and the fixed cutter 73 cooperate to cut the label. The L-shaped limiting blocks 75 are used to limit and fix the movable cutter 72 and the fixed cutter 73 to prevent the movable cutter 72 from moving excessively, and at the same time fix the fixed cutter 73 to prevent the fixed cutter 73 from moving downward.

[0030] Because some labels are quite tough, they can easily become stuck together and cannot be cut in one go. To address this, the moving cutter 72 has a gradually tilted blade length. This tilted design ensures that during the cutting process, the contact between the moving cutter 72 and the fixed cutter 73 is not simultaneous and complete, but rather progresses gradually from one end of the blade to the other. This progressive cutting method better handles tough labels, reducing the likelihood of sticking caused by sudden, forceful cutting by gradually applying pressure. Simultaneously, the tilted blade length also helps to disperse the stress generated during cutting, reducing the risk of label breakage due to stress concentration, improving cutting quality and stability, and ensuring that labels are accurately and completely cut to meet the requirements of subsequent labeling processes.

[0031] Furthermore, the movable cutter 72 and the fixed cutter 73 are U-shaped. The movable cutter 72 has guide grooves 720 on both sides along the axial direction. The fixed cutter 73 has two guide sleeves 730 on both sides that cooperate with the guide grooves 720. When the punching cylinder 74 drives the movable cutter 72 to move down for cutting, the guide grooves 720 and the guide sleeves 730 cooperate with each other to provide precise guidance for the movement of the movable cutter 72, ensuring that the movable cutter 72 moves down stably along the predetermined trajectory without deviation. This ensures the cooperation accuracy between the movable cutter 72 and the fixed cutter 73 and improves the cutting accuracy.

[0032] In addition, the fixed cutter 73 is provided with pressure blocks 76 on both sides for pressing the movable cutter 72; the guide sleeve 730 has a threaded hole, and a screw 77 is threadedly connected to the threaded hole. The screw 77 passes through the pressure block 76 and is connected to the threaded hole. The screw 77 is fitted with a pressure spring 78 for pressing the pressure block 76. With this structure, the pressure block 76 will generate a continuous and stable pressing force on the movable cutter 72 under the action of the pressure spring 78. This pressing force can not only further ensure the tight fit between the movable cutter 72 and the fixed cutter 73, preventing incomplete cutting or uneven label edges due to gaps between them during the cutting process, but also the elasticity of the pressure spring 78 can buffer the impact force generated when the movable cutter 72 moves down to a certain extent, reducing damage to the cutter and extending the service life of the cutter. Meanwhile, the threaded connection between the screw 77 and the threaded hole allows the clamping force of the pressure block 76 on the moving cutter 72 to be flexibly adjusted according to actual needs. When cutting labels of different materials and thicknesses, the compression degree of the pressure spring 78 can be changed by rotating the screw 77, thereby adjusting the clamping force to achieve the best cutting effect.

[0033] In summary, this semi-cutting feeder, through the rational arrangement of various components on the base 10, including the feeding shaft 20, the label peeling section 30, the pulling section 40, the backing paper receiving shaft 50, the moving label receiving platform 60, the label cutting section 70, and the belt and motor drive mechanism, achieves automatic label peeling, cutting, and conveying functions. Specifically, the label peeling section 30, through the cooperation of the suction plate 31 and the peeling blade 32, can stably and accurately peel the label from the backing paper; the moving label receiving platform 60, through the setting of the telescopic cylinder 62 and the non-stick plate 64, can flexibly receive and convey the cut labels; the label cutting section 70, through the precise cooperation of the moving cutter 72 and the fixed cutter 73, and the assistance of structures such as the guide groove 720, the guide sleeve 730, the pressure block 76, and the pressure spring 78, ensures accurate label cutting. This semi-cutting feeder not only improves the efficiency and accuracy of label processing but also reduces the difficulty and error of manual operation, providing strong support for automated production.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
