Description

Technical Field

[0001] This utility model relates to the field of hot stamping machines, specifically a hot stamping machine for producing anti-counterfeit wine boxes. Background Technology

[0002] In the production and processing of anti-counterfeiting wine boxes, hot stamping is one of the key processes to enhance the anti-counterfeiting performance and appearance of the wine boxes. It involves transferring metal foil or anti-counterfeiting logo patterns onto the surface of the wine box to form a decorative layer with visual recognition and anti-replication properties. Therefore, it requires high precision and production efficiency in hot stamping. Currently, the core working structure of hot stamping machines used in the production of anti-counterfeiting wine boxes in the industry usually includes a fixed worktable, positioning blocks, and hot stamping execution components (such as hot stamping plates, heating units, etc.). Among them, the positioning blocks, as the positioning carriers of the wine box blanks, need to be precisely matched with the outer dimensions of the anti-counterfeiting wine box to ensure that the hot stamping pattern can accurately correspond to the anti-counterfeiting logo area on the surface of the wine box, and avoid problems such as pattern offset or misalignment that affect the anti-counterfeiting effect.

[0003] The standard operating procedure of the existing hot stamping machine is as follows: The operator first places the wine box blank to be processed into the positioning block on the worktable and manually pushes the positioning block to the hot stamping station; then the hot stamping execution component moves down and completes the hot stamping process by heating and pressurizing. After the hot stamping process is completed, the operator needs to manually slide the positioning block out of the hot stamping station again, take out the finished wine box with hot stamping, put in a new wine box blank to be processed, and finally push the positioning block back to the hot stamping station to start the next hot stamping cycle.

[0004] When using existing hot stamping machines, workers can only unload finished products and load parts after the hot stamping process is completely finished and the positioning block has moved out of the hot stamping workpiece. While the hot stamping execution component is processing the wine box in the positioning block, workers must wait and cannot carry out loading and unloading operations simultaneously, creating two independent idle gaps, which is not conducive to speeding up production efficiency. Therefore, a hot stamping machine for anti-counterfeiting wine box production is proposed to address the above situation. Utility Model Content

[0005] To address the issue that in existing technologies, when the hot stamping execution component processes the wine box within the positioning block, workers must wait, which hinders production efficiency, this utility model proposes a hot stamping machine for producing anti-counterfeit wine boxes.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a hot stamping machine for producing anti-counterfeiting wine boxes, including a workbench, and a hot stamping mechanism for hot stamping anti-counterfeiting wine boxes is provided on the top of the workbench.

[0007] A turntable is rotatably mounted on the workbench. Three support blocks are evenly fixed on the top of the turntable. A positioning block is fixed on the top of each support block. Grooves are formed at both ends of the top of each support block. An installation groove is formed on the side wall of each groove. A spring is fixed to one end of the inner wall of the installation groove. An abutment rod is fixed to one end of the spring. The end of the abutment rod away from the spring extends out of the installation groove. When a wine box lid is engaged with the positioning block, the bottom of the wine box lid fits into the groove, and the outer wall of the wine box lid abuts against the end of the spring.

[0008] Preferably, the hot stamping mechanism includes a frame in the shape of an inverted "L" and fixed to one end of the top of the workbench. A cylinder is fixed to the top of the frame, and a mounting block is fixed to the telescopic end of the cylinder through the top of the frame. A hot stamping plate is fixed on the mounting block.

[0009] Preferably, a first through hole is provided at the center of the top of the frame, and the telescopic end of the cylinder passes through the first through hole.

[0010] Preferably, the top of the frame is provided with a second through hole at each end, and a guide rod is fitted inside the second through hole with clearance. The guide rod is T-shaped, and the thin end of the guide rod passes through the second through hole and is fixed to the top of the mounting block.

[0011] Preferably, the end of the abutment rod extending out of the mounting groove is hemispherical.

[0012] Preferably, the support block has openings on both sides, and the groove is C-shaped and communicates with the openings.

[0013] Preferably, a pad is fixed on one side plate of the frame, and the pad contacts the bottom surface of the support block extending outside the turntable.

[0014] Preferably, a rubber pad is fixed to the outer wall of the positioning block, and the rubber pad has anti-slip texture.

[0015] The advantages of this utility model are:

[0016] 1. This utility model utilizes a structure design of a turntable, a support block, and a positioning block. The turntable is driven by a servo motor to achieve continuous station switching. When the hot stamping of the wine box on one of the positioning blocks is completed, the turntable can transfer the hot stamped product to the unloading station and simultaneously transfer the positioning block that has been loaded to the hot stamping station. The entire switching process does not require manual intervention, realizing continuous operation of "processing-switching-reprocessing". In mass production scenarios, the equipment can always be in a state of high-efficiency operation, avoiding efficiency loss caused by manual operation interruption. Compared with traditional equipment, it can improve processing efficiency.

[0017] 2. This utility model, through the structural design of groove, mounting groove, spring and abutment rod, ensures the stability of the wine box lid during rotation and hot stamping operations by placing the wine box lid to be processed on the positioning block, with the side of the wine box lid inserted into the groove and abutted by the abutment rod, thus ensuring the quality of processing.

[0026] 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 scope of protection of the present utility model.

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

[0028] This application discloses a hot stamping machine for producing anti-counterfeit wine boxes. (See also...) Figures 1-6 A hot stamping machine for producing anti-counterfeit wine boxes includes a workbench 1, and a hot stamping mechanism 2 for hot stamping anti-counterfeit wine boxes is provided on the top of the workbench 1.

[0029] A turntable 3 is rotatably mounted on the worktable 1. The turntable 3 is rotatably mounted in the center of the worktable 1 through bearings. Its bottom is rigidly connected to the output shaft of the servo motor (not shown in the figure) through a coupling. The servo motor is set inside the worktable 1, which can realize stepless speed regulation and the angular positioning accuracy can reach ±0.05°, ensuring that the three positioning blocks 5 can accurately align with the hot stamping station.

[0030] Three support blocks 4 are evenly fixed on the top of the turntable 3. A positioning block 5 is fixed on the top of the support block 4. Grooves 41 are respectively opened at both ends of the top of the support block 4. An installation groove 42 is opened on the side wall of the groove 41. A spring 43 is fixed at one end of the inner wall of the installation groove 42. An abutment rod 44 is fixed at one end of the spring 43. The end of the abutment rod 44 away from the spring 43 extends out of the installation groove 42. When the wine box lid 6 is engaged on the positioning block 5, the bottom of the wine box lid 6 fits in the groove 41, and the outer wall of the wine box lid 6 abuts against the end of the spring 43.

[0031] Reference Figure 1 The hot stamping mechanism 2 includes a frame 20, which is in the shape of an inverted "L". The frame 20 is fixed to one end of the top of the workbench 1. A cylinder 21 is fixed to the top of the frame 20. The telescopic end of the cylinder 21 passes through the top of the frame 20 and is fixed to a mounting block 22. A hot stamping plate 23 is fixed on the mounting block 22.

[0032] Among them, cylinder 21 is a double-acting piston cylinder, and the extension and retraction speed can be controlled by a pneumatic regulating valve (not shown in the figure) to avoid rapid impact causing the wine box to shift.

[0033] Among them, the hot stamping plate 23 can be pre-printed with anti-counterfeiting codes, which are then hot stamped onto the wine box along with the product information.

[0034] Reference Figure 1 A first through hole is provided at the center of the top of the frame 20, and the telescopic end of the cylinder 21 passes through the first through hole.

[0035] Reference Figure 1 The top of the frame 20 has two through holes at its two ends. A guide rod is fitted inside the second through hole with a clearance. The guide rod is T-shaped and the thin end of the guide rod passes through the second through hole and is fixed to the top of the mounting block 22.

[0036] The mounting block 22 is a rectangular steel plate, and its bottom is bonded to the hot stamping plate 23 (copper with chrome plating) through thermally conductive silicone. The internally embedded heating tube (500W power) can stably control the temperature of the hot stamping plate 23 at 120-180℃ (accuracy ±2℃) to meet the hot stamping requirements of anti-counterfeiting metal foils of different materials. The gap between the guide rods on both sides and the second through hole is 0.05~0.1mm. The diameter of its "T"-shaped top is larger than the diameter of the through hole, forming a limiting structure to prevent the guide rods from falling off. At the same time, it ensures the perpendicularity of the mounting block to the frame 20 during the lifting process (deviation ≤0.03mm / m), avoiding the hot stamping plate tilting and causing pattern deformation.

[0037] Reference Figure 5 The end of the contact rod 44 extending out of the mounting groove 42 is hemispherical.

[0038] Reference Figure 2 , Figure 4 and Figure 5 The support block 4 has openings 40 on both sides of its side walls, and the groove 41 is C-shaped and connected to the openings 40.

[0039] The support block 4 is made of aluminum alloy and can be detachably connected to the top hole of the turntable 3 by bolts, which makes it easy to replace the support block with a suitable one according to the size of the wine box. The "C"-shaped groove 41 on the top of the support block is precisely matched with the bottom contour of the wine box lid 6. The openings 40 on both sides are 30-40mm wide, which makes it convenient for operators to put their fingers into the wine box to pick it up and put it down, without affecting the positioning stability of the lid in the groove 41.

[0040] Reference Figure 1 and Figure 6 A pad 7 is fixed on one side plate of the frame 20, and the pad 7 contacts the bottom surface of the support block 4 that extends out of the turntable 3.

[0041] The pad 7 is made of polytetrafluoroethylene and is fixed to the side plate of the frame 20 by countersunk bolts. Its top surface is flush with the upper surface of the turntable 3. When the support block 4 rotates with the turntable to the hot stamping station, the pad 7 and the bottom surface of the support block 4 are in complete contact. It can withstand the downward pressure applied by the cylinder during the hot stamping process, avoid the turntable 3 from deforming due to local stress, and further ensure the stability during hot stamping.

[0042] Reference Figure 2 and Figure 4 The outer wall of the positioning block 5 is fixed with a rubber pad, and the rubber pad has anti-slip texture.

[0043] Working principle: When in use, the electrical equipment in this device is connected to an external power source and switched on / off.

[0044] Material loading stage: The operator places the wine box lid 6 to be processed into the groove 41 of the support block 4 at the initial station (non-hot stamping station). The outer wall of the lid presses against the abutment rods 44 on both sides, causing the spring 43 to compress and generate a reverse elastic force. Through the symmetrical clamping action of the two abutment rods, the lid is accurately positioned in the center of the groove.

[0045] Station switching: The servo motor drives the turntable 3 to rotate 120° clockwise, and rotates the loaded support block 4 to the hot stamping station (directly below the hot stamping plate 23). At this time, the bottom surface of the support block 4 contacts the pad block 7 to form a rigid support. At the same time, the other two support blocks are rotated to the unloading station and the waiting loading station, respectively.

[0046] Hot stamping process: The telescopic end of cylinder 21 extends, driving mounting block 22 and hot stamping plate 23 to descend vertically along the guide rod. The hot stamping plate (preheated to the set temperature) comes into contact with the anti-counterfeiting metal foil on the surface of the wine box lid. Through the action of "high temperature + pressure", the metal foil pattern is transferred to the surface of the lid. After completion, the telescopic end of cylinder 21 retracts and the hot stamping plate 23 is reset.

[0047] Unloading and Cycle: The servo motor drives the turntable to rotate 120° again. The hot-stamped wine box rotates to the unloading station with the support block 4. The operator inserts his finger through the opening 40 of the support block 4 and lifts the box lid to overcome the resistance of the spring 43 and take out the finished product. At the same time, the new box lid to be processed is loaded at the loading station and the next hot-stamping cycle starts.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
