Description

Technical Field

[0001] This utility model relates to the field of hot stamping printing technology, specifically to an automatic hot stamping machine for the surface of glass bottles that can be automatically bottled. Background Technology

[0002] Due to the growing market demand for refined and personalized packaging, an automatic hot stamping machine for glass bottles has been established to hot stamp gold or other metallic patterns on the surface of glass bottles in industries such as cosmetics, wine, and health products, thereby enhancing the visual quality and added value of the products.

[0003] A Chinese patent with publication number CN214928113U discloses an automatic hot stamping machine for glass bottles capable of automatic bottling. Addressing the problems of existing hot stamping machines having a large footprint, only being able to perform hot stamping on one glass bottle at a time, and low efficiency affecting production capacity, the present invention proposes the following solution: It includes a base with conveyor platforms fixedly installed on both sides, and a worktable fixedly installed on the top of the base. The worktable is hollow, and unloading conveyor components are installed on the top of both conveyor platforms. Two symmetrically arranged rotating shafts are rotatably installed on the top of the worktable, and the two rotating shafts are connected to the same synchronization component. Compared with traditional hot stamping machines, this invention can simultaneously perform hot stamping operations on two glass bottles, resulting in high efficiency, small size, and small footprint, significantly improving the hot stamping production capacity of glass bottles.

[0004] The aforementioned patent still has the following shortcomings: During the use of the existing device, it is necessary to manually place the glass bottles one by one onto the conveying component, which not only increases labor costs, but also easily leads to interruption of material supply due to uneven manual operation rhythm, affecting the continuous operation efficiency of the equipment. At the same time, it is difficult to ensure that the initial positioning of each glass bottle is consistent when manually placing the bottles, which may cause deviation in the subsequent hot stamping position, reduce the hot stamping accuracy of the pattern, and restrict the realization of the equipment's production capacity advantage.

[0005] To address these issues, we propose an automatic hot stamping machine for glass bottles that can automatically fill bottles. Utility Model Content

[0006] This invention provides an automatic hot stamping machine for glass bottles that can automatically fill bottles, solving the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: An embodiment of this utility model provides an automatic hot stamping machine for the surface of glass bottles capable of automatic bottling, including a frame and further comprising: The hot stamping machine housing is fixed to the top of one side of the frame. A take-up roller is rotatably connected to one side of the hot stamping machine housing. A take-up motor with an output shaft end connected to the take-up roller is fixed to the other side of the hot stamping machine housing. Hot stamping film is wrapped around the outside of the take-up roller. A flip frame is rotatably connected to the bottom of the hot stamping machine housing. An electric hot stamping roller is installed at the bottom of the flip frame. A hydraulic push rod is rotatably connected to one side of the flip frame. The end of the hydraulic push rod away from the flip frame is rotatably connected to the hot stamping machine housing. A feeding structure is set on one side of the top of the frame. The feeding structure includes a pusher box, which is fixed to one side of the top of the frame. A storage box is fixed to one side of the top of the pusher box. A pneumatic push rod is fixed to the bottom of the pusher box. A movable frame is installed on the telescopic end of the pneumatic push rod. A baffle is fixed to the top of the movable frame. A placement slot is opened on the top of one side of the movable frame. A fixed structure, located at the top of the frame, is used to hold the bottle in place during the hot stamping process.

[0008] The above technical solution involves placing the bottle to be hot-stamped inside a storage box. A placement slot receives individual glass bottles falling from the storage box into the pusher box. A pneumatic pusher then moves the moving frame, pushing the glass bottle to a fixed structure. The fixed structure then positions the glass bottle. A winding motor drives the winding roller to release the hot-stamping film. Next, a flipping frame, pushed by a hydraulic pusher, brings the hot-stamping roller into contact with the glass bottle, transferring the metal layer from the hot-stamping film to the bottle surface. After hot-stamping is complete, the hydraulic pusher retracts, resetting the flipping frame and detaching the hot-stamping roller from the glass bottle. Simultaneously, the winding roller continues to rotate, winding up the used hot-stamping film to prepare for the next hot-stamping cycle.

[0009] Furthermore, a discharge rack is fixed to the other side of the top of the frame, a stop block is fixed to one side inside the discharge rack, a buffer pad is fixed to the other side inside the discharge rack, and tensioning racks are installed on both sides inside the hot stamping machine housing.

[0010] Through the above technical solutions, the rack can orderly store the hot-stamped glass bottles, the stop block can restrict the movement of the glass bottles and prevent them from exceeding the racking range, the buffer pad can reduce the impact force when the glass bottles enter the rack and prevent damage to the bottles, and the tensioning rack can keep the hot-stamping film taut and ensure that the film surface is flat during the hot-stamping process, thus improving the quality of hot-stamping.

[0011] Furthermore, the upper surface of the baffle is flush with the opening at the bottom of the storage box, and the movable frame extends to the bottom of the push box and is connected to the pneumatic push rod.

[0012] Through the above technical solution, the baffle can accurately block the bottom opening of the storage box when the moving frame moves, preventing excess glass bottles from falling. The connection between the moving frame and the pneumatic push rod can ensure that the pneumatic push rod stably drives the moving frame to move, so that the placement slot can accurately receive and push the glass bottles, improving the stability and accuracy of feeding.

[0013] Furthermore, the fixed structure includes a base frame fixed to the top of the machine frame. A bidirectional screw is rotatably connected inside the base frame, and a moving rod is threadedly connected to the outer side of each bidirectional screw. A servo motor with its output shaft end connected to the bidirectional screw is installed on one side of the bottom end of the base frame. A connecting sleeve is rotatably connected inside the top end of one set of moving rods, and a rotating seat is installed on one side of the other set of moving rods. A clamping plate is installed on one side of both the rotating seat and the connecting sleeve. An anti-slip pad is detachably installed on one side of the clamping plate. A stepper motor is fixed to one side of the top end of the base frame, and a drive shaft is installed on the output shaft end of the stepper motor.

[0014] The above technical solution uses a servo motor to drive a bidirectional screw to rotate, which clamps the glass bottle. A stepper motor then drives the transmission shaft to rotate, causing the glass bottle to rotate. This ensures that the surface of the glass bottle is evenly contacted by the hot stamping roller, guaranteeing the consistency and integrity of the hot stamping on the circumference.

[0015] Furthermore, a groove is provided on the outer side wall of the drive shaft, and a slide rail matching the groove is provided on the inner side wall of the connecting sleeve.

[0016] With the above technical solution, when the drive shaft rotates, the sliding groove and the sliding rail can drive the connecting sleeve to rotate synchronously, while not affecting the lateral movement of the connecting sleeve with the moving rod, ensuring stable power transmission when the glass bottle is rotated for hot stamping, and ensuring the uniformity of circumferential hot stamping.

[0017] Furthermore, the movable rod and the base frame form a sliding structure, and the movable rod is symmetrically distributed on the vertical center line of the bidirectional screw.

[0018] Through the above technical solution, the sliding structure enables the moving rod to slide stably along the base frame. The symmetrically distributed moving rods move synchronously in opposite directions under the drive of the bidirectional screw, ensuring that the clamping force of the two side plates on the glass bottle is balanced and improving the fixation stability.

[0019] Furthermore, the connecting sleeve and the rotating seat are located on the same horizontal center line, and the clamping plate forms a rotating structure between the rotating seat and the moving rod.

[0020] Through the above technical solution, the connecting sleeve and rotating seat on the same horizontal line ensure that the axis is horizontal when the glass bottle is clamped, and the rotating structure makes the clamping plate rotate synchronously with the glass bottle, avoiding the bottle body from shifting during hot stamping and improving the hot stamping accuracy to a certain extent.

[0021] The beneficial effects of this utility model are: 1. Glass bottles are stored in a storage box, and a pneumatic pusher drives a moving frame to move, allowing the placement slot to receive a single glass bottle and push it to the designated position. A baffle simultaneously prevents subsequent bottles from falling, thus achieving the automatic feeding function of this device. No manual bottle placement is required, reducing labor costs, ensuring continuous and stable feeding, and maintaining consistent initial positioning to reduce hot stamping deviations and improve equipment operating efficiency.

[0022] 2. A servo motor drives a bidirectional screw to rotate, which in turn moves symmetrically distributed moving rods to clamp the glass bottle. Anti-slip pads enhance friction, thus achieving the bottle-fixing function of this device. It can accommodate bottles of different sizes, provides a stable clamping grip, prevents displacement during hot stamping, improves pattern accuracy and consistency, and ensures processing quality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] like Figures 1 to 5 As shown, an embodiment of this utility model provides an automatic hot stamping machine for the surface of glass bottles capable of automatic bottling, including a frame 1, and further comprising: The hot stamping machine housing 3 is fixed to the top of one side of the frame 1. A take-up roller 6 is rotatably connected to one side of the hot stamping machine housing 3. A take-up motor 4 with the output shaft end connected to the take-up roller 6 is fixed to the other side of the hot stamping machine housing 3. Hot stamping film 5 is wrapped around the outside of the take-up roller 6. The flip frame 11 is rotatably connected to the bottom end inside the hot stamping machine housing 3. The bottom end of the flip frame 11 is equipped with an electric hot stamping roller 12. A hydraulic push rod 10 is rotatably connected to one side of the flip frame 11. The end of the hydraulic push rod 10 away from the flip frame 11 is rotatably connected to the hot stamping machine housing 3. The feeding structure 2 is set on one side of the top of the frame 1. The feeding structure 2 includes a push box 202, which is fixed to one side of the top of the frame 1. A storage box 201 is fixed on one side of the top of the push box 202. A pneumatic push rod 204 is fixed at the bottom of the push box 202. A movable frame 203 is installed at the telescopic end of the pneumatic push rod 204. A baffle 205 is fixed at the top of the movable frame 203. A placement slot 206 is opened at the top of one side of the movable frame 203. The fixing structure 9 is set at the top of the frame 1 and is used to fix the position of the bottle during the hot stamping process.

[0027] A discharge rack 7 is fixed on the other side of the top of the frame 1. A stop block 14 is fixed on one side inside the discharge rack 7. A buffer pad 8 is fixed on the other side inside the discharge rack 7. Tensioning racks 13 are installed on both sides inside the hot stamping machine housing 3.

[0028] In this embodiment of the invention, the bottle to be hot-stamped is placed inside the feeding structure 2. When the equipment is started, the feeding structure 2 pushes the bottle toward the hot-stamping roller 12, and the fixing structure 9 fixes the position of the bottle. The winding motor 4 drives the winding roller 6 to rotate, thereby releasing the wrapped hot-stamping film 5. At the same time, the hot-stamping film 5 is kept taut under the action of the tensioning frame 13 to ensure flatness. Then, the flipping frame 11 starts to rotate under the push of the hydraulic push rod 10, so that the hot-stamping roller 12 contacts the glass bottle. The hot-stamping roller 12 transfers the metal layer on the hot-stamping film 5 to the surface of the glass bottle. After hot-stamping is completed, the hydraulic push rod 10 retracts, driving the flipping frame 11 to reset and the hot-stamping roller 12 to detach from the glass bottle. At the same time, the winding roller 6 continues to rotate to wind up the used hot-stamping film 5 to prepare for the next hot-stamping. The hot-stamped glass bottle is transported to the discharge rack 7 and is protected from collision damage by the buffer pad 8.

[0029] like Figures 1 to 4 As shown, the upper surface of the baffle 205 is flush with the opening at the bottom of the storage box 201, and the movable frame 203 extends to the bottom of the push box 202 and is connected to the pneumatic push rod 204.

[0030] In this embodiment of the invention, when the equipment is in the loading state, multiple sets of glass bottles are placed into the storage box 201 by means of conveying equipment or manual handling. When the placement slot 206 moves to the opening at the bottom of the storage box 201, the glass bottles fall into the placement slot 206 under the action of gravity. At this time, the pneumatic push rod 204 begins to extend and drive the moving frame 203 to move towards the hot stamping area. At the same time, the baffle 205 moves to the bottom opening of the storage box 201 to block the subsequent glass bottles from falling. After the glass bottles are pushed to the designated position, the pneumatic push rod 204 retracts and drives the moving frame 203 to reset. The baffle 205 moves away from the storage box 201 and the next glass bottle falls into the push box 202, thereby realizing automatic continuous loading.

[0031] like Figures 1 to 5 As shown, the fixed structure 9 includes a base frame 901, which is fixed to the top of the frame 1. A bidirectional screw 907 is rotatably connected inside the base frame 901, and moving rods 908 are threaded onto the outer sides of the bidirectional screw 907. A servo motor 909, whose output shaft end is connected to the bidirectional screw 907, is mounted on one side of the bottom of the base frame 901. A connecting sleeve 905 is rotatably connected to the top of one set of moving rods 908, and a rotating seat 910 is mounted on one side of the other set of moving rods 908. Clamping plates 906 are mounted on one side of both the rotating seat 910 and the connecting sleeve 905. One side of the clamping plate 906 can... The anti-slip pad 903 is disassembled and installed. A stepper motor 902 is fixed on one side of the top of the base frame 901. A drive shaft 904 is installed at the output shaft end of the stepper motor 902. A slide groove is opened on the outer side wall of the drive shaft 904. A slide rail matching the slide groove is provided on the inner side wall of the connecting sleeve 905. A sliding structure is formed between the moving rod 908 and the base frame 901. The moving rod 908 is symmetrically distributed on the vertical center line of the bidirectional screw 907. The connecting sleeve 905 and the rotating seat 910 are located on the same horizontal center line. The clamping plate 906 forms a rotating structure between the rotating seat 910 and the moving rod 908.

[0032] In this embodiment of the invention, when the glass bottle is pushed to the bottom of the hot stamping roller 12 by the feeding structure 2, the servo motor 909 starts and drives the bidirectional screw 907 to rotate, causing the two sets of moving rods 908 to move along the axis of the bidirectional screw 907 and move closer to each other. At the same time, the rotating seat 910 at the top of the moving rod 908 and the connecting sleeve 905 move closer together, causing the clamping plates 906 on both sides to gradually clamp the glass bottle. The anti-slip pad 903 on one side of the clamping plate 906 contacts the surface of the glass bottle to increase friction and prevent the glass bottle from sliding. Simultaneously, the glass bottle can be adjusted according to its properties. Replace the anti-slip pads 903 of the corresponding shape at both ends of the bottle to ensure a tight fit. When hot stamping is required on the circumference of the glass bottle, the stepper motor 902 starts and drives the transmission shaft 904 to rotate through the output shaft. Since the slide rail on the inner side wall of the connecting sleeve 905 matches the slide groove on the outer side wall of the transmission shaft 904, the connecting sleeve 905 rotates with the transmission shaft 904 and drives the glass bottle to rotate synchronously under the action of the rotating seat 910 through the clamping plate 906, so that the surface of the glass bottle is evenly contacted by the hot stamping roller 12, ensuring the consistency and integrity of the hot stamping on the circumference.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
