Description

Technical Field

[0001] This utility model relates to an in-mold label collection mechanism for a die-cutting machine. Background Technology

[0002] Existing die-cutting machines come in various forms. Some cut small pieces of in-mold label from rolls of material, while others cut large pieces. These large pieces of in-mold label are typically tens of centimeters to over a meter in length and at least ten centimeters in width, especially some large fan-shaped pieces. Because die-cutting machines operate at high speeds, cutting and conveying in-mold label can be completed in about a second. The in-mold label's propulsion into the receiving platform comes from the front rollers. Due to air resistance, the forward speed of the entire in-mold label varies, with the front portion detaching from the rollers often moving slower than the rear. As a result, when large pieces of in-mold label separate from the roll and move towards the collection platform, they tend to overlap or pile up haphazardly, causing considerable trouble for the collection process. Summary of the Invention

[0003] The purpose of this invention is to provide an in-mold label collection mechanism that can prevent in-mold labels from overlapping or stacking haphazardly.

[0004] The present invention achieves the above objectives as follows: An in-mold label collection mechanism includes a frame, an in-mold label receiving platform mounted on the frame, and a pressing mechanism at the front end of the in-mold label entering the receiving platform. The pressing mechanism includes a cylinder and a pressing component, and the pressing component is connected and fixed to the free end of the cylinder, which is fixed on the support.

[0005] The bracket includes a support column and a crossbeam fixed on the frame. The crossbeam is fixed on the support column, and a support beam is fixed between the crossbeams. The support beam is fixedly connected to the cylinder through a connection, and the support beam can be fixed at any position on the crossbeam.

[0006] The receiving platform is equipped with a baffle above it, and the front end of the baffle has a notch for the pressing component to pass through.

[0007] The baffle is mounted on the support via a lifting frame. The lifting frame includes a vertical block fixedly connected to the crossbeam. A screw and an adjusting shaft are mounted on the vertical block. The screw and the adjusting shaft are connected by gear transmission. A connecting rod is fixed on a slider that is connected to the screw transmission. The connecting rod is fixedly connected to the baffle via a lifting block.

[0008] The vertical block has a vertical elongated through hole, and the connecting rod passes through the elongated through hole to connect with the slider.

[0009] The receiving platform is equipped with an air blowing pipe at its front end. The air blowing pipe is located below the in-mold adhesive when it enters the receiving platform, and the direction of air outlet is diagonally above the in-mold adhesive's forward direction.

[0010] There are two air blowing pipes, with the other one located above the in-mold sticker when it enters the receiving platform. The air blowing direction is diagonally below the in-mold sticker's forward direction, and the air blowing directions of the two air blowing pipes form an angle that blows the in-mold sticker forward.

[0011] The pressing component is a flat pressing block.

[0012] The receiving platform is a planar belt conveyor platform, and the pressing component is a roller, the roller's movement direction being parallel to the belt.

[0013] The bracket has a stop at the rear.

[0014] The beneficial effects of this utility model are: when the in-mold sticker is completely detached from the conveyor roller of the die-cutting machine, the cylinder of the pressing mechanism of this utility model will control the lower pressing component to briefly press the rear part of the in-mold sticker onto the receiving platform, so that the entire in-mold sticker stops moving forward, thereby allowing the in-mold sticker to fall flat on the receiving platform, which facilitates the next step of collection. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments: Figure 1 This is a three-dimensional structural diagram of the present invention; Figure 2 This is another three-dimensional structural diagram of the present invention; Figure 3 yes Figure 1 Enlarged view of point A; Figure 4 yes Figure 2 Enlarged view of point B. Detailed Implementation

[0016] Reference Figures 1 to 4 The in-mold label collection mechanism includes a frame 1, on which an in-mold label receiving platform 2 is mounted. A pressing mechanism 3 is located at the front end of the in-mold label entering the receiving platform 2. The pressing mechanism 3 includes a cylinder 32 and a pressing component 31, with the pressing component 31 connected and fixed to the free end of the cylinder 32, which is fixed to a bracket 4. When the in-mold label is completely detached from the conveyor roller of the die-cutting machine, the cylinder 32 of the pressing mechanism 3 controls the pressing component 31 to briefly press the rear portion of the in-mold label onto the receiving platform 2, stopping the entire in-mold label from moving forward and allowing it to fall flat onto the receiving platform 2 for easy collection.

[0017] The support frame 4 includes a support column 41 and a crossbeam 42 fixed to the frame 1. The crossbeam 42 is fixed to the support column 41, and a support beam 43 is fixed between the crossbeams 42. The support beam 43 is fixedly connected to the cylinder 32 via a connecting block 5. The support beam 43 can be fixed at any position on the crossbeam 42. The position of the pressing mechanism 3 of this invention can be adjusted by changing the position of the connecting block 5 on the support beam 43 or the position of the support beam 43 and the crossbeam 42, thereby adapting to the pressing component 31 pressing down on in-mold stickers of different sizes and shapes, ensuring that different in-mold stickers can fall flat on the receiving platform 2. To ensure that the pressing mechanism 3 presses down on the rear part of the in-mold sticker more accurately, a monitoring photoelectric sensor 9 can be installed on the support frame 4. The photoelectric sensor 9 is also located at the front end where the in-mold sticker enters the receiving platform 2.

[0018] To prevent the in-mold sticker from arching upwards during its forward movement, a baffle 6 is provided above the receiving platform 2. In addition, the front end of the baffle 6 is provided with a notch 61 for the pressing component to pass through. The size or length of the notch 61 can be determined according to the size or movement of the in-mold sticker to accommodate the position adjustment needs of the pressing component.

[0019] Additionally, the baffle 6 is mounted on the support 4 via a lifting frame 7. The lifting frame 7 includes a vertical block 71 fixedly connected to the crossbeam 42. A screw 72 and an adjusting shaft 73 are mounted on the vertical block 71. The screw 72 and the adjusting shaft 73 are connected by a gear 74. A connecting rod 75 is fixed to a slider 76, which is connected to the screw 72. The connecting rod 75 is fixedly connected to the baffle 6 via a lifting block 77. Rotating the adjusting shaft 73 will cause the screw 72 to rotate. The rotating screw 72 will then cause the slider 76, connecting rod 75, lifting block 77, and baffle 6 to rise and fall, thereby adjusting the distance between the bottom surface of the baffle 6 and the receiving platform. This ensures that the baffle 6 can effectively prevent different in-mold materials from arching and overlapping.

[0020] To simplify the structure of the lifting frame 7 and facilitate installation and maintenance, the vertical block 71 is provided with a vertical elongated through hole 711, and the connecting rod 75 passes through the elongated through hole 711 and connects with the slider 76.

[0021] To further prevent the in-mold label from arching and overlapping, an air blowing pipe 8 is provided at the front end of the receiving platform 2. The air blowing pipe 8 is located below the in-mold label as it enters the receiving platform 2, and the air outlet direction is diagonally above the in-mold label's forward movement direction. The air blown out by the air blowing pipe 8 can effectively increase the forward momentum of the front part of the in-mold label, preventing the rear part from moving at an excessively higher speed than the front part.

[0022] To further prevent the in-mold stickers from arching and overlapping, two air pipes 8 are used. The other pipe is located above the in-mold sticker entering the receiving platform 2, and the air outlet direction is diagonally downwards from the in-mold sticker's forward direction. The air outlet directions of the two air pipes form an angle that blows the in-mold sticker forward. This design can further reduce the speed difference between the front and rear parts of the in-mold sticker, effectively preventing the in-mold stickers from overlapping and ensuring that each piece of in-mold sticker lands orderly on the receiving platform.

[0023] The pressing component 31 is a flat pressing block. The flat pressing block briefly presses the rear part of the in-mold sticker onto the receiving platform, so that the entire in-mold sticker stops moving forward and falls flat on the receiving platform, making it convenient for workers to collect the in-mold sticker.

[0024] In addition, the receiving platform 2 can be designed as a flat belt conveyor platform, and the pressing component 31 is a roller, with the roller's movement direction parallel to the belt. This design can press the rear part of the in-mold sticker onto the receiving platform, stopping the entire in-mold sticker from moving forward and allowing it to fall flat on the receiving platform. It also allows the flat belt to easily transport the in-mold sticker to a more convenient collection location, without the two interfering with each other.

[0025] To prevent the in-mold sticker from falling to the ground due to excessive speed, a stop block 10 is provided at the rear of the bracket 4.
