[0028] Reference Figures 1 to 3 The punching device of the embodiment of the present application includes a positioning component 200, at least one group of punching components 300 and at least one group of heating components 400.
[0029] The positioning assembly 200 is used to position and fix the plastic product 500 .
[0030] The punching assembly 300 includes a first punching member 350 and a second punching member 330 that cooperate with each other. The first punching member 350 is used to support the position of the plastic product 500 to be punched, and the second punching member 330 is configured to be able to extend and retract toward the first punching member 350. The punching operation of the plastic product 500 is completed through the cooperation of the first punching member 350 and the second punching member 330.
[0031] The heating component 400 can generate hot air, and heat the position of the plastic product 500 to be punched by setting the hot air at a preset temperature, so that the punching operation can be performed better, and the hair generated by the punching can be removed in time when the punching is completed.
[0032] Furthermore, the punching equipment of the present application includes a mounting frame 100, and the positioning component 200, the punching component 300 and the heating component 400 are all fixed in the mounting frame 100. A protective enclosure is arranged on the periphery of the mounting frame 100. One side of the protective enclosure is open for loading and unloading of plastic products 500, and a proximity sensor 110 is also provided on the open side of the protective enclosure. The proximity sensor 110 is used to sense whether someone enters the protective enclosure. When the controller receives a trigger signal from the proximity sensor 110, the controller suspends the action of the punching component 300 to ensure personal safety.
[0033] Among them, before punching, the plastic product 500 is positioned and fixed on the positioning component 200, so that the first punching member 350 is pressed against the position of the plastic product 500 to be punched, and the position of the plastic product 500 to be punched and fixed on the positioning component 200 is preheated and softened by the heating component 400. After preheating, the second punching member 330 moves under the instruction of the controller and extends toward the first punching member 350. The second punching member 330 cooperates with the first punching member 350 to complete the punching of the plastic product 500. During the retraction of the second punching member 330, the heating component 400 continues to blow out hot air to heat so that the hair generated by the punching can be wiped off. The removal of the hair is convenient, and the surface of the plastic product 500 after punching is more complete and smooth, which effectively improves the punching yield of the plastic.
[0034] The punching equipment of the present application integrates the softening, punching and lint removal processes of plastic into one device, effectively streamlining the punching operation process of the plastic product 500. In addition to loading and unloading, the punching operation is automated, and the lint is removed by the hot air generated by the heating component 400 without the need for additional processes, thereby effectively improving the production efficiency of the plastic product 500.
[0035] In some embodiments, the punching assembly 300 further includes a sliding member 320 and a driving member 310. The sliding member 320 is configured to be able to slide, and the second punching member 330 is fixed to the sliding member 320. Specifically, the second punching member 330 is detachably fixed to the sliding member 320 so that second punching members 330 of different sizes can be quickly replaced according to different hole sizes. The second punching member 330 is a punching knife, and the first punching member 350 has a die hole that is compatible with the second punching member 330. The hole required for the plastic product 500 is formed by extrusion and shearing of the punching knife and the die hole, and the driving member 310 is used to drive the sliding member 320 close to or away from the first punching member 350 to complete the punching operation.
[0036] In some embodiments, the driving member 310 can be a pneumatic cylinder or an oil cylinder. In other embodiments, the driving member 310 can also be an electric push rod. In the embodiment of the present application, the driving member 310 is a pneumatic cylinder. Cylinder drive can effectively increase the punching speed.
[0037] Specifically, the punching assembly 300 includes a fixed base 301. A sliding member 320 is slidably mounted on the fixed base 301 via a linear guide structure, enabling the sliding member 320 to slide toward the first punching member 350. The driving rod of the driving member 310 is connected to the sliding member 320 via a floating joint. The sliding member 320 has connecting plates on both sides, each of which is connected to the fixed base 301 via a linear guide structure. The linear guide structure includes cooperating slide rails and sliders. The slide rails are fixed to the fixed base 301, and the connecting plates are fixedly connected to the sliders.
[0038] In some embodiments, the punching assembly 300 further includes a collection box 120 for collecting and storing waste generated during punching. Specifically, the first punching member 350 has a waste discharge channel internally, one end of which connects to the die hole and the other end leads to the collection box 120. The waste generated by punching is directed through the waste discharge channel to the collection box 120, where it is collected for batch processing.
[0039] In some embodiments, such as Figure 5 and Figure 6As shown, the punching assembly 300 also includes a pre-press 340, which is disposed within the sliding member 320 and positioned between the first punching member 350 and the second punching member 330. The pre-press 340 is capable of rebounding. As the punching process progresses and the second punching member 330 completes its punching process, the pre-press 340 contacts the plastic product 500 before the second punching member 330. During this process, the pre-press 340 is compressed, applying a certain pre-pressure to the surface of the plastic product 500. This serves to pre-press the area to be punched and prevent excessive deformation of the punched area of the plastic product 500 during punching, effectively improving the punching quality. After the punching operation is completed, as the second punching member 330 returns to its original position, the pre-press 340 also returns to its original position. Due to the rebound force, the pre-press 340 maintains a distance from the end of the second punching member 330, allowing it to contact the plastic product 500 before the second punching member 330 the next time.
[0040] Furthermore, the punching assembly 300 further includes a rebound member 360, and the pre-pressing member 340 is slidably disposed on the sliding member 320. Under the action of the rebound member 360, the pre-pressing member 340 has a tendency to move toward the first punching member 350. Specifically, as Figure 5 As shown, the pre-pressing member 340 is provided with multiple guide rods. The ends of the guide rods pass through the sliding member 320 and are inserted into the connecting member provided on the sliding member 320. The rebound member is located between the connecting member and the sliding member 320, so that the pre-pressing member 340 can slide along the axial direction of the second punching member 330. When punching, the pre-pressing member 340 drives the guide rods to move, and the guide rods compress the rebound member 360 toward the connecting member. Specifically, the rebound member 360 is a spring, which is sleeved on the guide rods. The guide rods are provided with a boss for limiting the spring, and the boss compresses the spring.
[0041] In some embodiments, the pre-pressing member 340 has a central portion with a relief hole for the second punching member 330 to pass through. The relief hole facilitates the punching of the second punching member 330 and the first punching member 350. The relief hole is sized to match the diameter of the second punching member 330, so that the unhollowed portion of the pre-pressing member 340 can effectively pre-press the portion of the plastic product 500 that does not need to be punched.
[0042] In some other embodiments, such as Figure 3 As shown, the positioning assembly 200 includes several positioning members 210 and several pressing members 220. A pressing member 220 is provided near each positioning member 210. The pressing member 220 can be flipped over the positioning member 210 to press the plastic product 500 positioned on the positioning member 210.
[0043] Specifically, in the embodiment of the present application, the positioning member 210 has a contoured surface that matches the shape of the plastic product 500, and the flipping of the clamping member 220 is achieved by a lever-type cylinder 221. The lever-type cylinder 221 has a connecting rod that can be flipped 90°, and the clamping member 220 is fixed on the connecting rod.
[0044] In some specific embodiments, Figures 1 to 3 As shown, there are four groups of punching assemblies 300, and four groups of heating assemblies 400 are also provided accordingly. The number of punching assemblies 300 provided corresponds one to one with the number of heating assemblies 400 provided, that is, one group of punching assemblies 300 is equipped with one group of heating assemblies 400, and the air outlet of each group of heating assemblies 400 faces the first punching part 350 of the corresponding punching assembly 300, so that the position to be punched of the plastic product 500 can be heated and softened before punching.
[0045] Furthermore, the heating component 400 includes an adjusting component and a hot air gun. The hot air gun has an electric heating wire and a wind tube for generating wind inside. By controlling the temperature of the electric heating wire, the temperature of the hot air blown out can be effectively controlled to achieve different temperature adjustments and adapt to the heating and softening of different plastic products 500. The adjusting component is used to adjust the blowing angle of the hot air gun so that the blowing angle of the hot air gun can be adjusted according to the shape of different plastic products 500.
[0046] In a specific embodiment, Figure 6 As shown, the adjustment member includes a first connecting rod 371, a second connecting rod 372 and a third connecting rod 373. The second connecting rod 372 is rotatably connected to the first connecting rod 371. The rotational connection between the second connecting rod 372 and the first connecting rod 371 is locked by a bolt so that the angle between the second connecting rod 372 and the first connecting rod 371 can be adjusted. The third connecting rod 373 is connected to the second connecting rod 372 by a ball joint structure so that the angle between the third connecting rod 373 and the second connecting rod 372 can be adjusted in a three-dimensional plane, and the hot air gun is fixed to the third connecting rod 373. The above-mentioned adjustment member can freely and flexibly adjust the blowing angle of the hot air gun.
[0047] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
