Description

Technical Field

[0001] This utility model relates to the field of sticker processing technology, specifically a sticker cutting device for a sticker printing machine. Background Technology

[0002] Self-adhesive stickers are widely used in packaging, advertising, signage, and decorative materials. As a key piece of equipment in the production of these products, the sticker printing machine's subsequent cutting process directly determines the dimensional accuracy and quality of the finished stickers. Traditional sticker cutting devices, especially when performing multi-stage parallel straight-line cutting (such as cutting wide rolls of material into multiple narrow rolls of a specific width), generally suffer from the following technical problems:

[0003] (1) When it is necessary to change the cutting position, the operator usually needs to manually loosen and move the position of multiple cutting units (blade holders) one by one. This process is not only time-consuming and laborious, but also heavily relies on the operator's experience and visual inspection, which is very easy to generate cumulative errors, resulting in inconsistent widths of each cutting strip, which cannot meet the production requirements of high-precision products.

[0004] (2) On traditional equipment, fine position adjustments are difficult to quantify. Operators cannot quickly and intuitively obtain the specific displacement of each tool holder. They can only verify it by repeated measurement and trial cutting, which greatly reduces the efficiency of machine adjustment and increases the scrap rate and material consumption during debugging.

[0005] (3) As a consumable part, the cutting knife needs to be replaced or sharpened regularly. Many existing devices have the cutting knife and the knife holder as an integrated design or fixed connection. When replacing it, the entire knife holder needs to be disassembled or professional tools are used, which is a complicated process and affects the continuity of production.

[0006] Therefore, the market urgently needs a sticker cutting device that is highly automated, easy to adjust, has visual feedback, and operates stably to meet the needs of modern production with small batches and multiple varieties. Utility Model Content

[0007] To achieve the above objectives, the present invention provides the following technical solution: a sticker cutting device for a sticker printing machine, comprising a support assembly, the support assembly comprising a stabilizing mechanism, the stabilizing mechanism comprising two symmetrically arranged stabilizing side plates, an adjusting rod for synchronously adjusting multiple cutting workpieces being threadedly connected at the middle between the two stabilizing side plates, and stabilizing rods providing stable support being fixed at both ends between the two stabilizing side plates.

[0008] The support assembly is equipped with a cutting component for cutting stickers. The cutting component includes multiple blade holders. A connecting hole is opened in the middle of the multiple blade holders, and sleeve hole one and sleeve hole two are opened at both ends respectively. The connecting hole is threaded to the side of the adjusting rod, while sleeve hole one and sleeve hole two are movably sleeved on the side of the corresponding stabilizing rod.

[0009] The cutting mechanism is installed at the bottom of the blade holder and is attached to the sticker surface of the platform below.

[0010] Preferably, the stabilizing mechanism includes a mounting plate arranged parallel to the back of the stabilizing side plate, and a connecting rod is fixed on the mounting plate.

[0011] Preferably, the two stabilizing rods have opposite outer surfaces and limit grooves along their length.

[0012] The tool holder has locating screws threaded to both ends. The front end of the locating screw passes through the corresponding sleeve hole and fits against the inner wall of the limiting slide groove.

[0013] Preferably, the cutting mechanism includes a mounting groove at one end of the bottom of the blade holder and a mounting plate installed inside therein, with the cutting blade fixed at the bottom of the mounting plate.

[0014] Preferably, the top of the mounting plate is provided with a plug rod, and the mounting groove is provided with a plug hole, into which the plug rod is inserted.

[0015] Preferably, a positioning hole is provided on the side of the insertion rod, and a positioning rod is movably sleeved on the side of the knife holder, with one end of the positioning rod inserted into the positioning hole.

[0016] Preferably, the tool holder is provided with a marking mechanism, which includes a connecting groove opened at one end of the side of the tool holder, a rotating ball rotatably connected in the connecting groove, and numerical values ​​circumferentially arranged on the side of the rotating ball.

[0017] Preferably, a linkage rod is fixed to one end of the rotating ball, and a gear is fixed to one end of the linkage rod;

[0018] The side of the stabilizing rod fitted inside the second sleeve hole has a toothed groove along its length, and the gear meshes in the toothed groove.

[0019] Compared with the prior art, the sticker cutting device for a sticker printing machine provided by this utility model has the following advantages:

[0020] 1. The sticker printing machine uses a sticker cutting device, which is connected to the adjusting rod by a screw thread on the blade holder and slides on the stabilizing rod. By simply rotating the adjusting rod in the clockwise or counterclockwise direction, all blade holders can be driven to move synchronously in the same direction. The blade adjustment speed is fast and the relative displacement between each blade holder can be absolutely guaranteed, which greatly improves the machine adjustment efficiency and spacing stability.

[0021] 2. The sticker cutting device used in this sticker printing machine uses positioning screws at both ends of each cutter holder. When all the positioning screws on the cutter holders are tightened, the cutter holders are locked in their current positions, and the adjusting rods cannot be rotated. This ensures that the entire cutting assembly has excellent rigidity and stability during high-speed operation, thereby guaranteeing a smooth and flat cutting edge. When adjustment is needed, simply loosen all the positioning screws to unlock the entire system for synchronous adjustment. The operation is simple and reliable.

[0022] 3. The sticker cutting device of this sticker printing machine has a marking mechanism on the knife holder. This mechanism accurately converts the linear displacement of the knife holder into the rotation of the rotating ball through the meshing of the gear and the tooth profile groove on the side of the stabilizing rod. The operator can clearly observe the change of the value on the rotating ball through the magnifying glass above the knife holder, so as to directly and quantitatively read the fine-tuning distance.

[0023] 4. The sticker cutting device of this sticker printing machine adopts an independent mounting plate and plug-in positioning rod fixing method for the cutting mechanism, which makes the replacement of the cutting blade extremely simple. Maintenance personnel do not need to disassemble the heavy blade holder. They can simply pull out the positioning rod to remove the entire cutting module for replacement or maintenance, which greatly reduces downtime and improves the availability and maintenance convenience of the equipment.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1 - Figure 5 As shown, the sticker cutting device for the sticker printing machine proposed in this embodiment includes a support component 1. The support component 1 includes a stabilizing mechanism 11. The stabilizing mechanism 11 includes two vertically symmetrically arranged stabilizing side plates 111. Two mounting plates 112 are arranged parallel to each other on the top and bottom of the back of each stabilizing side plate 111. A circular hole is opened on the mounting plate 112. A connecting rod 113 is fixed in the hole by a threaded connection. The connecting rod 113 is fixed to the output end of the electric push rod through its top end. When the electric push rod is operating, its output end drives the entire device to move up and down, so that the cutting workpiece below can be cut to fit stickers of different thicknesses.

[0034] Two stabilizing side plates 111 are provided with round holes in the middle and at both ends. The two ends of the adjusting rod 12 are installed in the round holes in the middle of the corresponding stabilizing side plates 111 by ball bearings (the outer ring of the bearing is fixed in the round hole, while the inner ring is fixed on the side of the adjusting rod 12). The two stabilizing rods 13 are threadedly connected to the corresponding round holes at one end of the two stabilizing side plates 111 to ensure the stability of the stabilizing rods 13. The two stabilizing rods 13 have limit grooves 131 on their opposite outer surfaces along their length.

[0035] The support assembly 1 is equipped with a cutting assembly 2 for cutting stickers. The cutting assembly 2 includes multiple blade holders 21. A connecting hole 211 is provided in the middle of the multiple blade holders 21, and sleeve hole 1 212 and sleeve hole 213 are provided at both ends respectively. The connecting hole 211 is threaded to the side of the adjusting rod 12, while sleeve hole 1 212 and sleeve hole 213 are movably sleeved on the side of the corresponding stabilizing rod 13. This allows the adjusting rod 12 to rotate and use the threaded engagement force to adjust the multiple cutting workpieces to move synchronously in one direction, so that the cutting workpieces are aligned with the corresponding linear cutting position above the sticker.

[0036] Multiple tool holders 21 are threaded to both ends with positioning screws 22. The front end of the positioning screw 22 passes through the corresponding sleeve hole and fits against the inner wall of the limiting slide groove 131. By rotating the positioning screw 22 clockwise or counterclockwise, its front end can be pressed against or disengaged from the corresponding wall surface inside the limiting slide groove 131. When the front ends of the positioning screws 22 on all tool holders 21 are pressed against the wall surface, the tool holders 21 are in a fixed state and the adjusting rod 12 cannot be rotated. When the front ends of the positioning screws 22 on all tool holders 21 are disengaged from the wall surface, the tool holders 21 are in a movable state. At this time, the adjusting rod 12 can be rotated clockwise or counterclockwise to adjust the displacement of multiple tool holders 21.

[0037] A cutting mechanism 23 is installed at the bottom of the blade holder 21. The cutting mechanism 23 is attached to the sticker surface on the lower platform. The mechanism includes a mounting groove 231 at one end of the bottom of the blade holder 21 and a mounting plate 232 installed inside it. The length and width of the mounting plate 232 match the inside of the mounting groove 231. A cutting blade 233 is fixed at the bottom of the mounting plate 232, so that when the output end of the electric push rod moves down, the cutting blade 233 is attached to the sticker surface.

[0038] Meanwhile, the top of the mounting plate 232 is provided with a rod 234, and the mounting groove 231 is provided with a hole 235. The rod 234 is inserted into the hole 235. The side of the rod 234 is provided with a positioning hole 236. The side of the blade holder 21 is movably sleeved with a positioning rod 237. One end of the positioning rod 237 is inserted into the positioning hole 236. When the mounting plate 232 is installed in the mounting groove 231, the rod 234 is inserted into the hole 235, and the positioning rod 237 is inserted into the positioning hole 236 from the side of the blade holder 21, thereby fixing the cutting mechanism 23 to the blade holder 21.

[0039] In addition, the tool holder 21 is provided with a marking mechanism 24. The marking mechanism 24 includes a connecting groove 241 opened at one end of the side of the tool holder 21. A rotating ball 242 is rotatably connected in the connecting groove 241. The side of the rotating ball 242 is provided with a value 2421 (digital millimeter-level marking) that makes it easy to know the adjustment distance when adjusting the displacement.

[0040] Meanwhile, a linkage rod 243 is fixed to one end of the rotating ball 242, and a gear 244 is fixed to one end of the linkage rod 243. The side of the stabilizing rod 13, which is fitted into the sleeve hole 213, has a tooth profile groove 132 along its length direction. The bottom of the tooth profile groove 132 has tooth profile patterns. The gear 244 meshes in the tooth profile groove 132. A magnifying glass 25 that can see inside is installed on the top of the tool holder 21 and directly above the connecting groove 241. When the front ends of the positioning screws 22 at both ends of a single tool holder 21 are in the disengaged state, by pushing and pulling the tool holder 21, the gear 244 meshes with the tooth profile in the tooth profile groove 132. The gear 244 drives the rotating ball 242 to rotate through the linkage rod 243. The corresponding value can be observed through the magnifying glass above to understand the distance of the displacement fine adjustment.

[0041] The working principle of the sticker cutting device for the sticker printing machine proposed in this embodiment is as follows: In use, multiple blade holders 21 are equidistantly threaded to the side of the adjusting rod 12 (the spacing of the blade holders 21 is set according to the actual width of the sticker to be cut), and the two ends of the blade holders 21 are movably sleeved on the side of the stabilizing rod 13. At this time, by rotating the adjusting rod 12, the cutting blade 233 below the blade holder 21 is positioned at the required linear cutting position above the sticker. Then, the electric push rod is controlled to move down, so that the cutting blade 233 is attached to the sticker surface, thereby controlling the operation of the conveying mechanism to cut the sticker.

[0042] To ensure that the bottom of the cutter 233 is accurately aligned with the required linear cutting position above the sticker, loosen the positioning screws 22 on all the cutter holders 21 (disengaging the front end from the corresponding wall of the limiting slide groove 131), and rotate the adjusting rod 12 to cause the cutter holders 21 to move. At this time, the meshing force between the gear 244 and the tooth profile in the tooth profile groove 132 causes the gear 244 to drive the rotating ball 242 to rotate. The adjustment distance can be determined by observing the corresponding value above the rotating ball 242 through the magnifying glass 25.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
