Description

Technical Field

[0001] This invention specifically relates to a device for punching holes in toy packaging film in one step. Background Technology

[0002] After toys are wrapped and sealed, they expand due to the residual air inside the film bag, taking up space inside the packaging box. Therefore, the operators on the packaging line will first punch holes in the packaging film containing the toys to allow the air to escape, thus not taking up space inside the packaging box.

[0003] However, existing toy packaging film punching devices are mostly large-scale automated equipment, which are not suitable for operators to cooperate with in packing operations on the packaging workshop assembly line. Therefore, there is a need for a small punching device that is convenient for operators to operate quickly. However, traditional manual punching or single-head punching machines require multiple, step-by-step operations on multiple sides of the packaging film. After punching a hole or a side, it is necessary to reposition or operate once, resulting in extremely low production efficiency, which cannot meet the needs of mass production. Moreover, the use of exposed high-temperature punching heads or simple mechanical punches poses a significant safety hazard of burns or pinching injuries to operators. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a one-time perforation device for toy packaging film.

[0005] The technical solution adopted by this invention to solve its technical problem is: A one-time perforation device for toy packaging film includes a base plate, a first pneumatic perforation mechanism, a second pneumatic perforation mechanism, a third pneumatic perforation mechanism, a fourth pneumatic perforation mechanism, a U-shaped anti-scalding plate, a PLC controller, a solenoid valve assembly, and control buttons. The first pneumatic perforation mechanism is vertically mounted on the base plate via a bracket with its perforation end facing downwards. The second and third pneumatic perforation mechanisms are located on opposite sides in front of the first pneumatic perforation mechanism and are fixedly installed with the base plate. The perforation ends of the second and third pneumatic perforation mechanisms are opposite to each other. The fourth pneumatic perforation mechanism is located in front of the first pneumatic perforation mechanism and is fixedly installed with the base plate. The U-shaped anti-scalding plate is fixedly installed with the base plate and is used to cover the second, third, and fourth pneumatic perforation mechanisms. The PLC controller is located on one side of the first pneumatic perforation mechanism and is fixedly installed with the base plate. The solenoid valve assembly is located on one side of the PLC controller and is fixedly installed with the base plate.

[0006] Preferably, a positioning frame strip is fixedly installed at the center of the base plate by bolts.

[0007] Preferably, the first pneumatic drilling mechanism, the second pneumatic drilling mechanism, the third pneumatic drilling mechanism and the fourth pneumatic drilling mechanism have the same structure.

[0008] Preferably, the first pneumatic drilling mechanism includes a drive cylinder, a connecting plate mounted on the output end of the drive cylinder, connecting bolts passing through both ends of the connecting plate, an aluminum block fixedly assembled with the connecting bolts, a copper column inserted into the front end face of the aluminum block, an assembly hole opened from the side of the aluminum block, and a heating rod inserted into the assembly hole and connected to the PLC controller.

[0009] Furthermore, the front end of the assembly hole is provided with an internal thread, and the wiring end of the heating rod is provided with a stud head.

[0010] Preferably, the bottom surface of the U-shaped anti-scalding plate is welded with a support block that is higher than the second, third, and fourth pneumatic drilling mechanisms, and the support block is provided in three pieces and evenly distributed.

[0011] Preferably, the PLC controller is connected to the solenoid valve assembly and control buttons.

[0012] Preferably, the solenoid valve assembly is connected to the first pneumatic drilling mechanism, the second pneumatic drilling mechanism, the third pneumatic drilling mechanism and the fourth pneumatic drilling mechanism respectively.

[0013] Preferably, the method of using the toy packaging film punching device includes the following steps: S1. Preparation stage: The operator turns on the power of the device, the PLC controller and solenoid valve group are started, the packaged toy products are placed on the base plate, and the positioning frame strip in the center of the base plate can be used for position correction and fixation to ensure that the packaging film is in a flat state. At the same time, the heating rods in the first, second, third and fourth pneumatic punching mechanisms are powered on and preheated to reach the preset working temperature. S2. Start Drilling: The operator presses the control button to send a start signal to the PLC controller. After receiving the signal, the PLC controller outputs control commands to the solenoid valve group according to the preset program. The solenoid valve group controls the air passages to the first, second, third, and fourth pneumatic drilling mechanisms simultaneously or in a specific sequence according to the commands. The drive cylinder of the first pneumatic drilling mechanism pushes the connecting plate, aluminum block, and front copper column downward to drill vertical holes in the top of the packaging film. The drive cylinders of the second and third pneumatic drilling mechanisms act simultaneously, pushing their heating copper columns to move relative to each other from both sides to drill holes on the left and right sides of the packaging film simultaneously. The drive cylinder of the fourth pneumatic drilling mechanism pushes the heating copper column forward to drill holes on the front side of the packaging film.

[0014] S3. Reset Phase: After drilling is completed, the PLC controller switches the air path through the solenoid valve group, causing the drive cylinders of the first, second, third, and fourth pneumatic drilling mechanisms to retract the aluminum block and copper column, detach them from the packaging film, and return them to their initial positions. S4. Remove the workpiece: The operator removes the punched toy packaging product from the device; S5. Cyclic operation: Place the next product to be processed and repeat steps S3 to S4 to achieve continuous operation.

[0015] The beneficial effects of this invention are: 1. By integrating the first, second, third, and fourth pneumatic drilling mechanisms, the top, sides, and front of the machine can be drilled simultaneously or sequentially in one working cycle. The operator only needs to place the product and press a button once, which greatly shortens the processing time of a single product and achieves efficient continuous operation. 2. The copper pillar is heated by a heating rod, and the high temperature instantly melts through the packaging film, resulting in a hole with smooth, burr-free edges and good sealing. The drilling action is driven by a cylinder, ensuring stable force. The PLC controller programmatically controls the process, ensuring that the stroke, time, and pressure of each drilling are consistent, thus guaranteeing the uniformity and stability of drilling quality for all products. In addition, the positioning frame provides a precise positioning reference, ensuring that the product is placed in the same position every time, fundamentally solving the problem of hole position deviation. 3. The U-shaped anti-scalding plate is specially designed to cover the second, third, and fourth pneumatic punching mechanisms on the sides and front, forming a physical isolation layer that effectively prevents operators from accidentally touching high-temperature components. In addition, the entire punching process is completed automatically by the equipment in the isolated state. Personnel only need to enter the operating area after the equipment is reset, which greatly reduces the risk of workplace injury. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0018] Example A one-time punching device for toy packaging film, such as Figure 1-5 As shown, the system includes a base plate 1, a first pneumatic drilling mechanism 2, a second pneumatic drilling mechanism 3, a third pneumatic drilling mechanism 4, a fourth pneumatic drilling mechanism 5, a U-shaped anti-scalding plate 6, a PLC controller 7, a solenoid valve assembly 8, and control buttons 9. The first pneumatic drilling mechanism 2 is vertically mounted on the base plate 1 via a bracket, with its drilling end facing downwards. The second pneumatic drilling mechanism 3 and the third pneumatic drilling mechanism 4 are located on either side in front of the first pneumatic drilling mechanism 2 and are fixedly installed to the base plate 1. The second pneumatic drilling mechanism 3... The punching end is opposite to the punching end of the third pneumatic punching mechanism 4. The fourth pneumatic punching mechanism 5 is located in front of the first pneumatic punching mechanism 2 and is fixedly installed with the base plate 1. The U-shaped anti-scalding plate 6 is fixedly installed with the base plate 1 and is used to cover the second pneumatic punching mechanism 3, the third pneumatic punching mechanism 4 and the fourth pneumatic punching mechanism 5. The PLC controller 7 is located on one side of the first pneumatic punching mechanism 2 and is fixedly installed with the base plate 1. The solenoid valve group 8 is located on one side of the PLC controller 7 and is fixedly installed with the base plate 1.

[0019] By integrating the first pneumatic drilling mechanism 2, the second pneumatic drilling mechanism 3, the third pneumatic drilling mechanism 4, and the fourth pneumatic drilling mechanism 5, the top, sides, and front holes can be drilled in one go, simultaneously, or sequentially within a work cycle. The operator only needs to place the product and press a button once, which greatly shortens the processing time of a single product and achieves efficient continuous operation.

[0020] A positioning frame 11 is fixedly installed in the center of the base plate 1 by bolts. Specifically, the positioning frame 11 enables the rapid positioning and fixing of the workpiece, ensuring that the position is consistent each time, thereby ensuring the accuracy of the drilling position. At the same time, it can be adjusted according to the product size, enhancing the versatility and adaptability of the device.

[0021] In this embodiment, the first pneumatic drilling mechanism 2, the second pneumatic drilling mechanism 3, the third pneumatic drilling mechanism 4, and the fourth pneumatic drilling mechanism 5 have the same structure.

[0022] The first pneumatic drilling mechanism 2 includes a drive cylinder 21, a connecting plate 22 mounted on the output end of the drive cylinder 21, connecting bolts 23 passing through both ends of the connecting plate 22, an aluminum block 24 fixedly assembled with the connecting bolts 23, a copper column 25 inserted into the front end face of the aluminum block 24, an assembly hole 26 opened from the side of the aluminum block 24, and a heating rod 27 inserted into the assembly hole 26 and connected to the PLC controller 7.

[0023] See also Figure 5The front end of the mounting hole 26 is provided with an internal thread 261, and the terminal of the heating rod 27 is provided with a stud head 271. Specifically, when the heating rod 27 is inserted into the mounting hole 26, the stud head 271 cooperates with the internal thread 261 at the front end of the mounting hole 26, which is conducive to fastening the heating rod 27. When the driving cylinder drives the aluminum block 24 to extend and retract, the heating rod 27 is not easy to loosen.

[0024] It should be further explained that the aluminum block 24 has good thermal conductivity, which can quickly transfer the heat of the heating rod 27 to the copper column 25. After heating, the copper column 25 can contact the membrane bag for hot melting and punching. The heating rod 27 is fixed by the engagement of the stud head 271 and the internal thread 261, which is firm and reliable. It can withstand the vibration and impact brought by the reciprocating motion of the cylinder, prevent it from loosening during operation, and ensure the stability of heating and the safety of the equipment.

[0025] The bottom surface of the U-shaped anti-scalding plate 6 is welded with support blocks 61 that are higher than the second pneumatic drilling mechanism 3, the third pneumatic drilling mechanism 4, and the fourth pneumatic drilling mechanism 5. Three support blocks 61 are evenly distributed. The support blocks 61 maintain a certain distance between the U-shaped anti-scalding plate 6 and the heated aluminum block, forming a heat dissipation channel. This facilitates heat dissipation and prevents heat accumulation that could cause the anti-scalding plate itself to overheat, further enhancing safety. Furthermore, the design of the U-shaped anti-scalding plate 6 and its support blocks 61 is a core safety measure, establishing physical isolation in the high-temperature drilling work area and effectively preventing operators from being burned by accidental contact with high-temperature components.

[0026] The PLC controller 7 is connected to the solenoid valve assembly 8 and the control button 9. The solenoid valve assembly 8 is connected to the first pneumatic drilling mechanism 2, the second pneumatic drilling mechanism 3, the third pneumatic drilling mechanism 4, and the fourth pneumatic drilling mechanism 5, respectively. Specifically, the solenoid valve assembly 8 is connected to the drive cylinders in the first pneumatic drilling mechanism 2, the second pneumatic drilling mechanism 3, the third pneumatic drilling mechanism 4, and the fourth pneumatic drilling mechanism 5. Through the control of the PLC controller 7, the entire process can be automated, with precise settings for the sequence and timing of actions, ensuring an orderly, efficient, and error-free drilling process.

[0027] A one-time punching device for toy packaging film, the method of using which includes the following steps: S1. Preparation stage: The operator turns on the power of the device, the PLC controller 7 and the solenoid valve group 8 are started, the packaged toy products are placed on the base plate 1, and the positioning frame strip 11 in the center of the base plate can be used for position correction and fixation to ensure that the packaging film is in a flat state. At the same time, the heating rods in the first pneumatic punching mechanism 2, the second pneumatic punching mechanism 3, the third pneumatic punching mechanism 4 and the fourth pneumatic punching mechanism 5 are powered on to preheat and reach the preset working temperature. S2. Start Drilling: The operator presses the control button 9 to send a start signal to the PLC controller 7. After receiving the signal, the PLC controller 7 outputs control commands to the solenoid valve group 8 according to the preset program. The solenoid valve group 8 controls the air passages to the first pneumatic drilling mechanism 2, the second pneumatic drilling mechanism 3, the third pneumatic drilling mechanism 4, and the fourth pneumatic drilling mechanism 5 simultaneously or in a specific sequence. The drive cylinder of the first pneumatic drilling mechanism 2 pushes the connecting plate, aluminum block, and copper column at the front end to move downward, making vertical holes in the top of the packaging film. The drive cylinders of the second and third pneumatic drilling mechanisms 3 and 4 operate simultaneously, pushing their heating copper columns to move relative to each other from both sides, making holes in the left and right sides of the packaging film simultaneously. The drive cylinder of the fourth pneumatic drilling mechanism 5 pushes the heating copper column forward, making holes in the front side of the packaging film.

[0028] S3. Reset phase: After drilling is completed, PLC controller 7 switches the air path through solenoid valve group 8, so that the drive cylinders of the first pneumatic drilling mechanism 2, the second pneumatic drilling mechanism 3, the third pneumatic drilling mechanism 4, and the fourth pneumatic drilling mechanism 5 drive the aluminum block 24 and the copper column 25 to retract, detach from the packaging film, and return to the initial position. S4. Remove the workpiece: The operator removes the punched toy packaging product from the device; S5. Cyclic operation: Place the next product to be processed and repeat steps S3 to S4 to achieve continuous operation.

[0029] In step S3, the first pneumatic punching mechanism 2, the second pneumatic punching mechanism 3, the third pneumatic punching mechanism 4, and the fourth pneumatic punching mechanism 5, under the control of the PLC controller 7, simultaneously complete all punching operations on the top, front, and both sides of the packaging film in one go. Compared with traditional manual or single-head punching equipment that requires multiple positioning and multiple operations, integrating the punching process into one step significantly shortens the production cycle and is very suitable for mass production. Figure 1-4 The layout of the first pneumatic drilling mechanism 2, the second pneumatic drilling mechanism 3, the third pneumatic drilling mechanism 4, and the fourth pneumatic drilling mechanism 5 around the working area is clearly shown, intuitively demonstrating its one-time forming overall structure.

[0030] In summary, this device achieves high efficiency through automated synchronous operation, ensures high quality through PLC and precise positioning, guarantees high safety through anti-scalding plates and centralized control, and ensures long-term stable operation through reliable mechanical and electrical design. Therefore, in toy packaging film perforation applications, this device can significantly improve production efficiency, product quality, and operational safety.
