Description

Technical Field

[0001] This utility model relates to the field of slitting technology, and more specifically, to a slitting device for printing self-adhesive labels. Background Technology

[0002] In the production process of self-adhesive labels, the printed label substrate needs to undergo a slitting process to divide continuous rolls or large-format printed materials into single labels or narrow rolls that meet the required specifications. This facilitates subsequent processing steps such as die-cutting, lamination, and packaging. The performance of the slitting equipment directly affects the production efficiency and product quality of self-adhesive labels. With the continuous growth in demand for self-adhesive labels from industries such as packaging, logistics, and electronics, the market not only places higher demands on the printing accuracy and material adaptability of the labels but also sets more stringent standards for the automation level, slitting efficiency, and finished product qualification rate of the slitting process.

[0003] In the use of slitting equipment for self-adhesive label printing, the distance between the blades needs to be adjusted to meet different slitting width requirements. Currently, most methods use manual or semi-manual adjustment of the blade spacing. Operators must first stop the machine, turn the adjusting screw with a wrench to move the blade holder, and then repeatedly measure and calibrate the distance between adjacent blades with calipers. A single adjustment typically takes 15-30 minutes, which is time-consuming and affects production efficiency. Therefore, we propose a new slitting device for self-adhesive label printing. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a slitting device for self-adhesive label printing, so as to solve the technical problem that the current blade spacing adjustment consumes time and affects processing efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a slitting device for printing self-adhesive labels, including a slitting mechanism and an adjustment mechanism provided on the slitting mechanism. The slitting mechanism includes a base plate and a first support plate and a second support plate symmetrically arranged on the base plate, as well as a cutter shaft and a support roller rotatably installed between the first support plate and the second support plate. Blades are equidistantly arranged on the cutter shaft. The adjustment mechanism includes a threaded rod, a limiting rod, an adjustment plate for adjusting the blades, and a fixing rod. The adjustment plate is adjustablely arranged on the threaded rod and the limiting rod. The adjustment plate is provided with a plurality of positioning grooves, which are radially and equidistantly distributed along the long axis. Adjustment blocks for connecting with the threaded rod and the limiting rod are symmetrically arranged on the side end of the adjustment plate.

[0006] Preferably, the side end of the second support plate is rotatably mounted with gears that are respectively connected to the shaft of the cutter shaft and the shaft of the support roller, and the gears are meshed with each other. The second support plate is provided with a first motor, and the output shaft of the first motor is connected to the shaft of one of the gears.

[0007] Preferably, the outer surface of the cutter shaft is provided with positioning recesses, and the inner ring of the blade is provided with positioning protrusions, the positioning protrusions being located within the positioning recesses.

[0008] Preferably, L-shaped first mounting plates are symmetrically arranged on the first support plate, the threaded rod is rotatably mounted between the first mounting plates, a second motor for driving the threaded rod is provided on the first mounting plate, L-shaped second mounting plates are symmetrically arranged on the second support plate, and the limiting rod is mounted between the second mounting plates.

[0009] Preferably, the top of the first support plate and the second support plate are provided with a top plate, the bottom surface of the top plate is provided with a sliding groove, the top of the fixing rod is provided with a slider that is slidably installed in the sliding groove, the fixing rod passes through the positioning groove of the adjusting plate, the fixing rod is provided with a positioning hole, a positioning rod is provided between the first support plate and the second support plate, the positioning rod is located in the positioning hole, the bottom end of the fixing rod is provided with a mounting block, and fixing plates are symmetrically installed on the mounting block by bolts.

[0010] Preferably, the bottom end of the fixing plate is provided with an arc-shaped plate, the side of the arc-shaped plate that is in contact with the blade is provided with a rolling groove, a ball is provided in the rolling groove, and annular grooves are symmetrically provided on the outer surface of the blade, with the ball located in the annular groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model designs an adjustment plate structure with equidistant radial positioning grooves on the adjustment plate. The threaded rod drives the adjustment plate to move, and the positioning grooves can directly drive the fixed rod to synchronously adjust the blade position. The distance between adjacent blades can be increased or decreased with one click according to the equidistant distribution of the positioning grooves, eliminating the need for repeated measurements. This effectively shortens the adjustment time per cycle, significantly reduces downtime, improves overall production efficiency, and solves the problem of time-consuming blade spacing adjustment affecting processing efficiency.

[0013] 2. This utility model uses an arc-shaped plate at the bottom of the fixed plate to cooperate with an annular groove on the outer surface of the blade. The ball bearings inside the arc-shaped plate are embedded in the annular groove, which forms a stable axial limit on the blade without affecting the rotation of the blade. This design not only makes it easy to adjust the position of the blade, but also ensures that the blade will not move axially due to high-speed rotation or substrate tension during the slitting process, thus ensuring the stability of the blade rotation.

[0014] 3. This utility model forms an interlocking structure by using the positioning recess on the outer surface of the cutter shaft and the positioning protrusion on the inner ring of the blade, so that the blade can be positioned on the cutter shaft. When the cutter shaft rotates, it can drive the blade to rotate for cutting. Secondly, it can facilitate the movement of the blade along the long axis of the cutter shaft, so that the blade will not be circumferentially offset during the adjustment process.

Detailed Implementation

[0024] like Figures 1 to 8As shown, this utility model relates to a slitting device for printing self-adhesive labels, including a slitting mechanism 100 and an adjustment mechanism 200 provided on the slitting mechanism 100. The slitting mechanism 100 includes a base plate 101 and a first support plate 102 and a second support plate 103 symmetrically arranged on the base plate 101, as well as a cutter shaft 108 and a support roller 107 rotatably mounted between the first support plate 102 and the second support plate 103. Blades 111 are equidistantly arranged on the cutter shaft 108. The adjustment mechanism 200 includes a threaded rod 201, a limiting rod 202, and an adjustment plate 203 and a fixing rod 205 for adjusting the blades 111. The adjustment plate 203 is adjustablely arranged on the threaded rod 201 and the limiting rod 202. The adjustment plate 203 is provided with a plurality of positioning grooves 2032, which are radially equidistantly distributed along the long axis. Adjustment blocks 2031 for connecting with the threaded rod 201 and the limiting rod 202 are symmetrically arranged on the side end of the adjustment plate 203. The positioning grooves 2032 of the adjustment plate 203 of this utility model are radially and equidistantly distributed, which can drive the fixing rod 205 to realize the "one-click equidistant increase or decrease" of the blade 111 spacing, eliminating the need for repeated measurements and shortening the adjustment time. The arc plate 209 cooperates with the annular groove 1110 of the blade 111 to ensure that the blade 111 rotates stably without shifting, effectively improving the production and processing efficiency of the equipment.

[0025] Specifically, gears 109 are rotatably mounted on the side end of the second support plate 103, respectively connected to the shafts of the cutter shaft 108 and the support roller 107. The gears 109 mesh with each other. A first motor 110 is mounted on the second support plate 103, and the output shaft of the first motor 110 is connected to the shaft of one of the gears 109. Through the transmission method of the meshing gears 109, the power of the first motor 110 can be synchronously transmitted to the cutter shaft 108 and the support roller 107, ensuring the coordination and synchronicity of their rotation. This avoids deviations in label cutting caused by inconsistent speeds between the cutter shaft 108 and the support roller 107, ensuring the stability of the cutting process and the cutting quality.

[0026] Furthermore, the outer surface of the cutter shaft 108 is arrayed with positioning recesses, and the inner ring of the blades 111 is arrayed with positioning protrusions, which are located within the positioning recesses. This matching structure of positioning recesses and positioning protrusions enables the blades 111 to be quickly positioned on the cutter shaft 108, preventing the blades 111 from rotating circumferentially on the cutter shaft 108. This ensures that the blades 111 maintain the correct cutting angle during the slitting process and also guarantees that the blades 111 can accurately move to the target position when adjusting the spacing of the blades 111 later, preventing the blades 111 from deviating from their position during the adjustment process.

[0027] It is worth noting that L-shaped first mounting plates 105 are symmetrically arranged on the first support plate 102, and threaded rods 201 are rotatably installed between the first mounting plates 105. A second motor 204 for driving the threaded rods 201 is provided on the first mounting plate 105. L-shaped second mounting plates 106 are symmetrically arranged on the second support plate 103, and limiting rods 202 are installed between the second mounting plates 106. The L-shaped mounting plate provides stable mounting support for the threaded rod 201 and the limiting rod 202, ensuring their positional stability during device operation. The second motor 204 drives the threaded rod 201 to rotate, thereby driving the adjusting plate 203 to move smoothly. The limiting rod 202 restricts the direction of movement of the adjusting plate 203, preventing the adjusting plate 203 from deviating during movement and ensuring adjustment accuracy. During the movement of the adjusting plate 203, the fixing rod 205 can drive the blade 111 to move. Because the positioning grooves 2032 on the adjusting plate 203 are radially and equidistantly distributed, the distance between the connected blades 111 will increase or decrease accordingly, allowing for quick adjustment of the blade 111 spacing, facilitating the cutting of labels of different widths.

[0028] It is worth mentioning that the top of the first support plate 102 and the second support plate 103 is provided with a top plate 104, the bottom surface of the top plate 104 is provided with a sliding groove 1041, the top of the fixing rod 205 is provided with a slider 2051 that is slidably installed in the sliding groove 1041, the fixing rod 205 passes through the positioning groove 2032 of the adjusting plate 203, the fixing rod 205 is provided with a positioning hole 2052, a positioning rod 206 is provided between the first support plate 102 and the second support plate 103, the positioning rod 206 is located in the positioning hole 2052, the bottom end of the fixing rod 205 is provided with a mounting block 207, and a fixing plate 208 is symmetrically installed on the mounting block 207 by bolts. The groove 1041 on the top plate 104 cooperates with the slider 2051 at the top of the fixed rod 205 to guide the movement of the fixed rod 205, ensuring that the fixed rod 205 moves in a straight line during adjustment. The positioning rod 206 passes through the positioning hole 2052 to perform secondary positioning of the fixed rod 205, ensuring the stability of the fixed rod 205 and the stability of the position of the blade 111. The mounting block 207 is connected to the fixing plate 208 by bolts, which facilitates the disassembly and installation of the fixing plate 208 and makes it easier to maintain or replace the blade 111 in the future.

[0029] It is worth noting that the bottom end of the fixing plate 208 is provided with an arc-shaped plate 209. The side of the arc-shaped plate 209 that fits against the blade 111 is provided with a rolling groove, and a ball bearing 2091 is provided in the rolling groove. The outer surface of the blade 111 is symmetrically provided with annular grooves 1110, and the ball bearing 2091 is located in the annular grooves 1110. The shape of the arc-shaped plate 209 is adapted to the outer surface of the blade 111, which can better fit the blade 111. The ball bearing 2091 is located in the rolling groove and in the annular groove 1110 of the blade 111. Without affecting the normal rotation of the blade 111, it can axially limit the blade 111, prevent the blade 111 from axially moving during the slitting process, and ensure the accuracy of the slitting dimensions. At the same time, rolling friction has less resistance than sliding friction, and can reduce the obstruction to the rotation of the blade 111 when the spacing between the blades 111 can be adjusted.

[0030] Working Principle: This embodiment provides a slitting device for self-adhesive label printing. In use, firstly, according to the target width requirement of the self-adhesive labels to be slit, the second motor 204 is started. The second motor 204 drives the threaded rod 201 installed between the first mounting plates 105 to rotate. Since the adjusting plate 203 is connected to the threaded rod 201 and the limiting rod 202 installed between the second mounting plates 106 respectively through the adjusting block 2031 at its side end, when the threaded rod 201 rotates, it will drive the adjusting plate 203 to move smoothly along the length direction of the limiting rod 202. The limiting rod 202 can restrict the movement direction of the adjusting plate 203, preventing it from deviating. During the movement of the adjusting plate 203, the radially equidistant positioning grooves 2032 on its surface exert a pushing force on the fixed rod 205 passing through the positioning grooves 2032. The slider 2051 at the top of the fixed rod 205 slides along the sliding groove 1041 on the bottom surface of the top plate 104. At the same time, the positioning hole 2052 on the fixed rod 205 cooperates with the positioning rod 206 between the first support plate 102 and the second support plate 103 to ensure that the fixed rod 205 moves stably along a straight line. The arc plate 209 connected to the bottom of the fixed rod 205 through the mounting block 207 and the fixed plate 208 moves accordingly. The ball bearings 2091 in the rolling groove inside the arc plate 209 move with it. Within the annular groove 1110 located on the outer surface of the blade 111, the movement of the blade 111 is not affected by its subsequent rotation. Furthermore, because the positioning grooves 2032 are radially and equidistantly distributed, the distance between the blades 111 driven by adjacent fixing rods 205 will increase or decrease equidistantly, quickly adjusting the blade spacing to match the target width without requiring repeated manual measurements and calibrations. After adjustment, only the spacing of one blade 111 needs to be measured, significantly reducing the blade adjustment time. After adjustment, the first motor 110 is started, and the output shaft of the first motor 110 drives the connected gear 109 to rotate. This gear 109... The second support plate 103 engages with another gear 109 on its side, which in turn drives the cutter shaft 108 and the support roller 107 to rotate synchronously. The positioning recess on the outer surface of the cutter shaft 108 cooperates with the positioning protrusion on the inner ring of the blade 111 to ensure that the blade 111 rotates stably with the cutter shaft 108 without circumferential displacement. The self-adhesive label substrate to be cut passes between the cutter shaft 108 and the support roller 107. The rotating blade 111 cuts the substrate. During the cutting process, the arc plate 209 and the ball bearing 2091 cooperate to axially limit the blade 111 to prevent the blade 111 from moving and to ensure accurate cutting dimensions. The cut labels then enter the subsequent processing stage.
