Description

Technical Field

[0001] This application relates to the field of label processing equipment technology, and in particular to a cutting blade structure for a label cutting device. Background Technology

[0002] With the expansion of label applications into industries such as food, logistics, and daily necessities, the demand for labels is increasing daily, and higher requirements are being placed on label cutting quality and efficiency. For example, from small price tags for food packaging and large waybills in the logistics industry to thick material labels in the industrial sector, the market has created a rigid demand for label cutting equipment capable of cutting labels of various specifications. This is especially true in small-batch, multi-batch customized production scenarios, where the same production line needs to frequently cut labels of different lengths, widths, and thicknesses.

[0003] The existing label cutting equipment system has obvious shortcomings, making it difficult to cover the cutting needs of multiple specifications with a single machine: most companies need to configure special cutting equipment for different specifications of labels, such as desktop cutting machines for small price tags, wide roll cutting machines for large labels, and heavy-duty cutting equipment for thick material labels.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the cutting structure is usually fixed, making it difficult to flexibly adjust the cutting width and length, and also unable to adapt to the cutting needs of label paper of different thicknesses. It has poor adaptability to cutting labels of different specifications, which in turn affects the overall progress of label production. Utility Model Content

[0005] In order to improve the problem that the cutter structure is difficult to flexibly adjust the cutting width and length, and difficult to cut label paper of different thicknesses, this application provides a cutter structure for label cutting equipment.

[0006] The cutting blade structure for a label cutting device provided in this application adopts the following technical solution: A cutting structure for a label cutting device includes a cutting table and a driving assembly disposed on the cutting table for driving label movement. T-shaped plates slide vertically on both sides of the cutting table, and lifting assemblies for driving the T-shaped plates to slide vertically are disposed on both sides of the cutting table. A transverse cutting assembly for adjusting the label cutting width and a longitudinal cutting assembly for adjusting the label cutting length are disposed on the T-shaped plates. The transverse cutting assembly includes a support rod fixedly connected to one side of the T-shaped plate, several first sliders sliding on the support rod, and a first annular blade rotatably connected to one end of the first sliders near the cutting table. An abutment assembly for restricting the movement of the first sliders is disposed in the first sliders.

[0007] By adopting the above technical solution, the cutting table can provide a stable installation base for the drive assembly, T-shaped plate, horizontal cutting assembly, and vertical cutting assembly. The drive assembly drives the label paper to move stably on the cutting table, while the lifting assembly can adjust the distance between the horizontal and vertical cutting assemblies and the cutting table to adapt to the cutting needs of label paper of different thicknesses. When cutting the label, the label is placed on the cutting table, and the drive assembly drives the label to move on the cutting table. During the movement of the label, it is cut by the horizontal and vertical cutting assemblies. The horizontal cutting assembly can cut label paper of different widths, and the vertical cutting assembly can cut label paper of different lengths. This cutting structure improves the adaptability to cutting labels of different specifications through multi-dimensional adjustment capabilities, ensuring the continuity and efficiency of label production.

[0008] Optionally, the lifting assembly includes a first support plate disposed on one side of the cutting table and a cylinder mounted on the first support plate, wherein the piston end of the cylinder is fixedly connected to one side of the T-shaped plate.

[0009] By adopting the above technical solution, the lifting assembly can accurately control the distance between the horizontal cutting assembly and the vertical cutting assembly relative to the cutting table. During adjustment, the piston end of the cylinder extends or retracts and drives the T-plate, causing the T-plate to move vertically upward or downward. While the T-plate is moving, it drives the horizontal cutting assembly and the vertical cutting assembly to move, thereby adjusting the distance between the horizontal cutting assembly and the vertical cutting assembly and the cutting table.

[0010] Optionally, the longitudinal cutting assembly includes a guide rod disposed on one side of the T-shaped plate, a second slider slidably connected to the guide rod, a second annular blade rotatably connected to one end of the second slider near the cutting table, and a drive unit for driving the second slider to move along the guide rod.

[0011] By adopting the above technical solution, when cutting the length of the label, the driving unit drives the second slider, so that the second slider can move along the direction of the guide rod. While the second slider is moving, it drives the second ring knife to move, and the second ring knife cuts the label.

[0012] Optionally, the drive unit includes a first motor mounted on one side of the T-shaped plate, a lead screw rotatably connected inside the T-shaped plate, the lead screw being rotatably connected coaxially with the output shaft of the first motor, and the second slider being threadedly connected to the lead screw.

[0013] By adopting the above technical solution, when it is necessary to cut labels of different lengths, the speed of the first motor can be adjusted. After the speed of the first motor is adjusted, the output shaft of the first motor drives the lead screw to rotate, and the lead screw drives the second slider threaded on the lead screw, so that the second slider drives the second ring blade to move along the guide rod to cut the label.

[0014] Optionally, the support rod is provided with a scale groove for adjusting the distance between the two first sliders.

[0015] By adopting the above technical solution, when adjusting the cutting width of the label, the scale groove on the support rod allows the staff to quickly set the relative position of the two first sliders, ensuring the accuracy of the label width cutting size.

[0016] Optionally, the abutment assembly includes a bolt threaded into the first slider and a rubber block disposed at one end of the bolt near the support rod.

[0017] By adopting the above technical solution, when adjusting the cutting width of the label, first rotate the bolt, which drives the rubber block to move so that the rubber block no longer abuts the support rod. Then, adjust the distance between the two first sliders according to the actual production needs, and then adjust the distance between the two first annular blades.

[0018] Optionally, the driving assembly includes a driving roller rotatably connected inside the cutting table, a second support plate disposed on one side of the cutting table, and a second motor fixedly mounted on the second support plate. The driving roller is rotatably connected coaxially with the output shaft of the second motor. The driving roller is located below the first annular blade. The cutting table has a strip-shaped hole for driving the label to move.

[0019] By adopting the above technical solution, when the label is cut, the output shaft of the second motor drives the drive roller to rotate, and then the label is placed between the first ring knife and the drive roller. The label paper is conveyed through the clamping area between the first ring knife and the drive roller. Under the active conveying of the drive roller and the cutting action of the first ring knife, continuous cutting in the width direction of the label is achieved. The strip hole structure ensures effective contact between the drive roller and the label paper.

[0020] Optionally, the drive roller is provided with a rubber layer to increase the friction between the drive roller and the label.

[0021] By adopting the above technical solution, the rubber layer on the surface of the drive roller can significantly increase the friction between it and the label paper, ensuring that the label paper maintains a stable feed speed during the conveying and cutting process, and effectively avoiding cutting size deviation or conveying interruption caused by slippage.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The cutting blade structure of this label cutting equipment can be adapted to labels of different thicknesses, and the length and width of the label cutting can be flexibly and accurately adjusted, making it convenient for manufacturers to cut labels of different specifications according to actual production needs.

[0023] 2. It can drive the label to move smoothly and evenly along the cutting table through the drive roller and rubber layer, avoiding label deviation. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0028] This application discloses a cutter structure for a label cutting device.

[0029] Reference Figure 1 The cutting structure of the label cutting equipment includes a cutting table 1, a drive assembly 2, a T-shaped plate 3, a lifting assembly 4, a horizontal cutting assembly 5, and a vertical cutting assembly 6.

[0030] Reference Figure 1The drive assembly 2 is mounted on the cutting table 1 to drive the label to move along the cutting table 1. In this embodiment, there are two T-shaped plates 3, which slide vertically on both sides of the cutting table 1. There are two lifting assemblies 4, which are mounted on both sides of the cutting table 1 to drive the T-shaped plates 3 to slide vertically. The horizontal cutting assembly 5 and the vertical cutting assembly 6 are mounted on the T-shaped plates 3. In this embodiment, the horizontal cutting assembly 5 is located in front of the vertical cutting assembly 6. The horizontal cutting assembly 5 can adjust the cutting width of the label, and the vertical cutting assembly 6 can adjust the cutting length of the label. This allows the cutter structure to flexibly adjust the width and length of the label cutting, thus adapting to the cutting needs of different label specifications.

[0031] Reference Figure 1 and Figure 2 The lifting assembly 4 includes a first support plate 401 and a cylinder 402. The piston end of the cylinder 402 is fixed to one side of the T-shaped plate 3 by welding or threaded connection. The first support plate 401 provides stable support for the cylinder 402. When the piston of the cylinder 402 extends or retracts, it can drive the T-shaped plate 3 to slide vertically on both sides of the cutting table 1, thereby adjusting the distance between the transverse cutting assembly 5, the longitudinal cutting assembly 6 and the cutting table 1 to adapt to the cutting requirements of labels of different thicknesses.

[0032] Reference Figure 1 and Figure 3 The driving assembly 2 includes a driving roller 203, a second support plate 201, and a second motor 202. A strip-shaped hole 9 is provided on the cutting table 1, and a rubber layer 10 is provided on the driving roller 203. The driving roller 203 is rotatably connected to the cutting table 1. The second support plate 201 is welded to one side of the cutting table 1. The second motor 202 is mounted on the second support plate 201. The driving roller 203 and the output shaft of the second motor 202 are coaxially rotatably connected. When cutting the label, the second motor 202 drives the driving roller 203 and the rubber layer 10 on the driving roller 203 to rotate. The rubber layer 10, through friction, drives the label to move stably along the cutting table 1, so that the label can be cut by the transverse cutting assembly 5 and the longitudinal cutting assembly 6.

[0033] Reference Figure 1 , Figure 2 and Figure 4The transverse cutting assembly 5 includes a support rod 501, a first slider 502, and a first annular blade 503. The support rod 501 is positioned on one side of the T-shaped plate 3. The first slider 502 is slidably connected to the support rod 501. The first annular blade 503 is rotatably connected to the end of the first slider 502 near the cutting table 1 via a pin. When cutting the label in the width direction, the label is placed between the rubber layer 10 and the first annular blade 503. The second motor 202 drives the drive roller 203 and the rubber layer 10 to rotate. The rubber layer 10 drives the label to move stably along the cutting table 1. During this movement, the label contacts and is cut by the first annular blade 503, thus completing a precise cut in the width direction.

[0034] Reference Figure 4 , Figure 5 and Figure 6 The support rod 501 has a scale groove 8, and the first slider 502 is provided with an abutment component 7, which includes a bolt 701 and a rubber block 702.

[0035] Reference Figure 4 , Figure 5 and Figure 6 The bolt 701 is threaded into the first slider 502, and the rubber block 702 is located at the end of the bolt 701 near the support rod 501. When cutting labels of different widths, the bolt 701 is rotated first, causing the rubber block 702 to move and no longer abut against the support rod 501, thus releasing the restriction on the first slider 502 and allowing it to slide along the support rod 501. The distance between the first sliders 502 is then adjusted. The scale groove 8 on the support rod 501 facilitates the adjustment of the distance between the first sliders 502. After adjusting the distance between the first sliders 502, the bolt 701 is rotated in the opposite direction, causing the bolt 701 to push the rubber block 702 to move until the rubber block 702 abuts against the support rod 501, thereby locking the position of the first slider 502 and preventing displacement of the first slider 502 during the cutting process, which would cause deviation in the width of the label when the first ring cutter 503 cuts the label.

[0036] Reference Figure 2 , Figure 3 and Figure 4The longitudinal cutting assembly 6 includes a guide rod 602, a second slider 603, a second annular blade 604, and a driving unit 601. The guide rod 602 is located on one side of the T-shaped plate 3. The second slider 603 is slidably connected to the guide rod 602. The second annular blade 604 is rotatably connected to the end of the second slider 603 near the cutting table 1 via a pin. The driving unit 601 drives the second slider 603 to move along the direction of the guide rod 602. When the label needs to be cut along its length, the driving unit 601 drives the second slider 603 to move along the direction of the guide rod 602, causing the second slider 603 to drive the second annular blade 604 to quickly cut the label.

[0037] Reference Figure 2 , Figure 3 and Figure 4 The drive unit 601 includes a first motor 6011 and a lead screw 6012. The first motor 6011 is mounted on one side of the T-shaped plate 3, and the lead screw 6012 is rotatably connected inside the T-shaped plate 3. The lead screw 6012 is coaxially rotatably connected to the output shaft of the first motor 6011. A second slider 603 is threadedly connected to the lead screw 6012. The first motor 6011 is typically a stepper motor, which can precisely control the rotational speed of the lead screw 6012, thereby precisely controlling the movement position of the second slider 603. When cutting the label along its length, the output shaft of the first motor 6011 drives the lead screw 6012 to rotate. The lead screw 6012 then drives the second slider 603, which is threaded onto the lead screw 6012, allowing the second slider 603 to move the second annular blade 604 along the direction of the guide rod 602 to cut the label. If the label cutting length needs to be adjusted, this can be achieved by changing the rotational speed of the first motor 6011, making operation convenient and precision controllable.

[0038] The implementation principle of the cutter structure for a label cutting device in this application embodiment is as follows: When cutting the label, the distance between the first annular blade 503 and the second annular blade 604 and the cutting table 1 is first adjusted by the cylinder 402 to adapt to the cutting of labels of different thicknesses. After the adjustment is completed, the second motor 202 and the first motor 6011 are started. The output shaft of the second motor 202 drives the drive roller 203 and the rubber layer 10 to rotate. The label to be cut is placed between the first annular blade 503 and the rubber layer 10. Under the drive of the drive roller 203, the label moves along the cutting table. During the movement, the first annular blade 503 cuts the label in the width direction. At the same time, the output end of the first motor 6011 rotates periodically in both directions, driving the lead screw 6012 to rotate. 012 drives the second slider 603, which is threaded onto the lead screw 6012. This causes the second slider 603 to move the second annular cutter 604 along the direction of the guide rod 602 to cut the label in the length direction. When the cutting width of the label needs to be adjusted, the bolt 701 is rotated. The bolt 701 moves the rubber block 702 and it no longer abuts against the support rod 501. Then, the distance between the first sliders 502 is adjusted according to the actual production needs. The scale groove 8 on the support rod 501 makes it easy for the staff to make adjustments. After the adjustment is completed, the bolt 701 is rotated in the opposite direction, causing the bolt 701 to push the rubber block 702 to move until the rubber block 702 abuts against the support rod 501, preventing the first slider 502 from shifting during operation and affecting the cutting effect of the first annular cutter 503.
