Technical Field

[0001] This utility model relates to the field of coated paper cup processing, and in particular to a non-stick coated paper cup punching mold. Background Technology

[0002] Due to their excellent waterproofness, heat resistance, and portability, coated paper cups are widely used in the catering and beverage industries. In their production process, die-cutting is a key step that determines product quality and production efficiency. As the core equipment in this step, the die-cutting mold must simultaneously shape and divide the raw materials to quickly mass-produce paper cup semi-finished products that meet specifications.

[0003] With the increasing market demand for coated paper cups, higher requirements have been placed on the stability, precision and anti-stick performance of molds. In particular, in production, avoiding the sticking of paper cups to the mold after punching has become an important direction for improving production efficiency. However, traditional coated paper cup punching molds have shortcomings in practical applications.

[0004] After the coated paper cups are die-cut, due to the adhesiveness of the coating layer and the pressure during the forming process, the paper cups tend to stick tightly to the inner wall of the forming mold, making demolding difficult. This causes trouble for subsequent staff to retrieve the materials, increases the time spent on material retrieval, and leads to low efficiency.

[0005] To address this issue, a non-stick coating paper cup die-cutting mold is proposed. Utility Model Content

[0033] 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 protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 2This utility model provides an embodiment of a die for punching out coated paper cups that prevents sticking. The die includes a machine base 1, with a support 2 fixedly connected to the upper surface of the machine base 1. The machine base 1 and the support 2 are used to support the overall device. The support 2 is U-shaped with the opening facing downwards. A hydraulic rod 3 is provided on the lower surface of the support 2. The hydraulic rod 3 is existing technology and can be implemented by those skilled in the art. Since it is existing technology, it will not be described in detail in this case. The upper part of the machine base 1 is provided with a forming component for punching out coated paper cups. The upper part of the machine base 1 is also provided with an anti-sticking component to prevent coated paper cups from sticking after punching out.

[0035] Reference Figure 1 - Figure 3 The forming component includes a forming mold 41, which is fixedly mounted on the upper surface of the machine base 1 by bolts. The bottom end of the output shaft of the hydraulic rod 3 is fixedly mounted with a mounting plate 42 by bolts. Both the forming mold 41 and the mounting plate 42 can be disassembled, ensuring convenience and facilitating replacement with different models of molds. An extrusion mold 43 is fixedly connected to the lower surface of the mounting plate 42. The bottom end of the mounting plate 42 is provided with a dividing component to prevent the coated paper cups from sticking together during punching. A through forming groove is opened on the inner surface of the forming mold 41. The extrusion mold 43 is inserted into the inner wall of the forming groove, thereby pressing the raw material into a suitable shape and punching the raw material together.

[0036] Reference Figure 1 , Figure 3 , Figure 4 The anti-sticking assembly includes two sets of connecting plates 64 for ejecting the formed workpiece and preventing sticking. The two sets of connecting plates 64 are evenly fixed to the left and right sides of the mounting plate 42. A slot 65 is provided on the right surface of the left-side connecting plate 64. A positioning plate 61 is slidably connected to the inner wall of the machine base 1. The positioning plate 61 slides longitudinally. Connecting blocks 66 are fixedly connected to both ends of the upper surface of the positioning plate 61. An ejector 62 is fixedly connected to the upper surface of the positioning plate 61. The positioning plate 61, connecting blocks 66, and ejector 62 move synchronously. When the ejector 62 is in a low position, its… The upper surface is horizontal with the upper surface of the machine base 1. The inner wall on the right side of the connecting block 66 on the left side is elastically connected to the locking block 68 by the elastic element 67. The locking block 68 and the locking groove 65 fit together. The anti-adhesion component also includes a baffle 69 for positioning the locking block 68. The right surface of the baffle 69 on the left side protrudes from the right surface of the connecting plate 64 on the left side. The end of the baffle 69 away from the forming mold 41 is fixedly connected to the bracket 2. The upper surface of the positioning plate 61 is elastically connected to the inner wall of the machine base 1 by the elastic element 63. When the positioning plate 61 moves upward, it will squeeze the elastic element 63 to generate a reaction force.

[0037] Reference Figure 1 , Figure 3 , Figure 4The connecting plate 64 is L-shaped, and the locking block 68 is slidably connected to the left surface of the connecting block 66. When the locking block 68 retracts into the connecting block 66, it will squeeze the elastic element 67 to generate a reaction force. The locking block 68 is inserted into the inner wall of the slot 65. When the connecting plate 64 moves upward, it will drive the locking block 68 to move upward. However, since the right surface of the baffle 69 on the left protrudes from the right surface of the connecting plate 64 on the left, the locking block 68 cannot move above the baffle 69. The left half of the upper surface of the locking block 68 is set as an inclined surface that gradually slopes upward from left to right. When the inclined surface is squeezed, the locking block 68 will retract into the connecting block 66. The connecting block 66 and the ejector 62 are both slidably connected to the upper surface of the machine base 1 and move longitudinally. The center of the ejector 62 and the forming groove are located on the same axis. The baffle 69 is located in front of the connecting plate 64. The baffle 69 is locked into the upper surface of the locking block 68. When the locking block 68 moves upward, the inclined surface will be squeezed by the baffle 69.

[0038] Reference Figure 1 - Figure 2 The dividing component includes a cutting blade 51, which is fixedly connected to the lower surface of the mounting plate 42. The upper surface of the forming mold 41 is provided with a receiving groove 52, and the cutting blade 51 is inserted into the inner wall of the receiving groove 52 to divide the coated paper cup raw material.

[0039] Working principle: First, the raw material for coated paper cups is laid on the forming mold 41. Then, the hydraulic rod 3 is activated to push the mounting plate 42 downward. The mounting plate 42 drives the extrusion mold 43 and the cutting blade 51 to move downward simultaneously. The extrusion mold 43 is inserted into the forming groove of the forming mold 41 to press the raw material into the shape of a paper cup. At the same time, the cutting blade 51 is inserted into the receiving groove 52 to complete the punching and cutting of the raw material. Before punching and forming, the raw material is placed directly on the forming mold 41. In order to avoid the paper cups from sticking together after forming, the cutting blade 51 is used to cut the raw material at the edge of the paper cup to ensure the forming quality of the paper cup.

[0040] During this process, the connecting plates 64 on both sides of the mounting plate 42 move down and press the inclined surface of the locking block 68, causing the locking block 68 to compress the elastic element 67 and retract into the connecting block 66. When the forming mold 41 and the mounting plate 42 are in contact, the slot 65 will align with the locking block 68. Under the action of the elastic element 67, the locking block 68 will spring into the slot 65, realizing the locking of the connecting plate 64 and the connecting block 66.

[0041] After punching is completed, the hydraulic rod 3 drives the mounting plate 42 to reset upwards. The connecting plate 64 pulls the connecting block 66 and the positioning plate 61 upwards simultaneously through the locking block 68. At this time, the positioning plate 61 compresses the elastic element 63 to generate a reaction force. The upward movement of the positioning plate 61 will drive the ejector 62 to push the paper cup in the forming mold 41, making the paper cup and the forming mold 41 loose and creating a gap. This prevents the paper cup from sticking to the forming mold 41, making it easier for subsequent workers to pick up, reducing the picking time, and improving processing efficiency. When the connecting block 66 moves upwards, the baffle 69 will squeeze the inclined surface of the locking block 68 to make it retract. When the locking block 68 and the slot 65 are disengaged, the elastic force and gravity of the elastic element 63 will drive the positioning plate 61, the ejector 62, and the connecting block 66 to sink and reset, making it convenient for subsequent use.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
