Description

Technical Field

[0001] This utility model relates to the field of die-cutting technology, specifically to a device for preventing glue overflow in die-cut parts. Background Technology

[0002] Die-cut parts, as key functional components in industrial manufacturing, are widely used in fields such as electronics and information technology, automobile manufacturing, packaging and printing, and medical devices. They encompass products such as mobile phone accessories, automotive gaskets, self-adhesive labels, and medical dressings. Their processing precision and quality directly affect the performance and reliability of the final products. Among various die-cut parts, soft adhesive materials such as foam, double-sided tape, silicone, and hot melt adhesive films are particularly prone to adhesive overflow. These materials typically have high elasticity and low hardness, and their surfaces are coated with hot melt adhesives, water-based adhesives, etc. When subjected to the pressure and friction of the cutting tool during the die-cutting process, the adhesive is prone to overflowing from the cutting edge due to excessive fluidity.

[0003] Glue overflow can have multiple adverse effects on die-cutting processes: In terms of product quality, glue overflow can cause die-cut parts to deviate from tolerances, irregular adhesive edges can contaminate the product surface, and may even cause short circuits in precision electronic components; in terms of production efficiency, overflowing adhesive can easily stick to the cutting tools and equipment table, requiring frequent shutdowns for cleaning, increasing manual maintenance costs, and adhesive residue can cause subsequent material positioning deviations, reducing the stability of automated production lines; in terms of cost control, the decrease in yield, rework losses, and equipment wear caused by glue overflow, especially in high-precision, high-value die-cutting scenarios (such as optical films and medical dressings), will significantly increase the company's production costs and the difficulty of quality control. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for preventing glue overflow in die-cut parts.

[0005] The objective of this utility model can be achieved through the following technical solution: a die-cutting part anti-overflow glue treatment device, including a box body, a cooling chamber and a material chamber are provided inside the box body, the cooling chamber and the material chamber are separated by a partition, an evaporator connected to a refrigeration unit is provided in the cooling chamber, an air outlet is provided at the upper end of the partition and an air return outlet is provided at the lower end, a fan for driving airflow circulation is provided in the cooling chamber corresponding to the air outlet, a material rack for supporting the die-cutting parts is provided in the material chamber, and a box door corresponding to the material chamber is hinged on the box body.

[0006] Preferably, a heat insulation layer is provided between the refrigeration chamber, the material chamber and the housing.

[0007] Preferably, the air outlet is equipped with an airflow direction adjustment component.

[0008] Preferably, the airflow adjustment component includes a frame installed at the air outlet, at least two blades are rotatably arranged on the frame at intervals, one end of each blade is fixedly provided with a rocker arm, one end of each rocker arm is movably connected through a connecting plate, a cylinder is installed on the housing, and a connecting rod is hinged to the output end of the cylinder, one end of the connecting rod is hinged to the connecting plate.

[0010] Preferably, the material rack includes a support frame, on which support rods are spaced apart, and the ends of the support rods are threaded with retaining rings.

[0011] Preferably, a spacer ring is fitted onto the support rod.

[0012] The beneficial effects of this utility model are as follows: the cold air in the cooling chamber is driven by a fan to enter the material chamber through the air outlet.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] See Figures 1 to 4As shown, the structure of this utility model is as follows: a die-cutting part anti-overflow glue treatment device, including a box body 1, a refrigeration chamber 2 and a material chamber 3 inside the box body 1, separated by a partition 4. An evaporator 5 connected to a refrigeration unit is provided inside the refrigeration chamber 2. An air outlet 6 is provided at the upper end of the partition 4, and a return air outlet 7 is provided at the lower end. A fan 8 for driving airflow circulation is provided inside the refrigeration chamber 2 corresponding to the air outlet 6. A material rack 9 for supporting the die-cutting parts is provided inside the material chamber 3. A door corresponding to the material chamber 3 is hinged to the box body 1. Specifically, the core components of the refrigeration unit include a compressor, a condenser, and a throttling device. The compressor refrigerates the low-temperature, low-pressure... The refrigerant gas is compressed into a high-temperature, high-pressure gas, which releases heat and liquefies in the condenser. Then, it is depressurized and cooled by the expansion valve / capillary tube of the throttling device to a low-temperature, low-pressure gas-liquid mixture, and finally enters the evaporator 5 in the refrigeration chamber 2. In the evaporator 5, the liquid refrigerant evaporates and absorbs heat, reducing the air temperature in the refrigeration chamber 2. Subsequently, the fan 8 drives the cold air from the air outlet 6 at the upper end of the partition 4 into the material chamber 3 to process the die-cut parts on the material rack 9. After passing through the material chamber 3, the low-temperature airflow returns to the refrigeration chamber 2 from the return air outlet 7 at the lower end of the partition 4, forming a closed loop. This achieves pre-treatment and refrigeration of the roll material to be die-cut, thereby reducing the fluidity of the adhesive and suppressing the problem of adhesive overflow during die-cutting from the source.

[0023] Furthermore, a heat insulation layer is provided between the cooling chamber 2, the material chamber 3 and the box body 1. Specifically, a heat insulation layer such as PU foam or vacuum insulation material is added between the box body 1 and the cooling chamber 2 and the material chamber 3. The low thermal conductivity of the material insulation material is used to block the heat exchange between the box body 1 and the outside world, thereby reducing the loss of cold energy from the cooling chamber 2 and the material chamber 3 to the outside world and the penetration of external heat.

[0024] like Figure 2 As shown, the air outlet 6 is equipped with an air direction adjustment component 10. Specifically, the air direction adjustment component 10 is used to control the airflow direction to avoid excessive local temperature or uneven cooling in the material chamber 3 due to airflow dead angles, and further improve the consistency of the anti-overflow adhesive effect.

[0025] like Figure 3 As shown, the airflow adjustment component 10 includes a frame 1001 installed at the air outlet 6. At least two blades 1002 are rotatably mounted on the frame 1001 at intervals. One end of each blade 1002 is fixedly mounted with a rocker arm 1003. One end of each rocker arm 1003 is movably connected through a connecting plate 1004. A cylinder 1005 is mounted on the housing 1. A connecting rod 1006 is hinged to the output end of the cylinder 1005. One end of the connecting rod 1006 is hinged to the connecting plate 1004. Specifically, the cylinder 1005 drives the connecting plate 1004 to move through the connecting rod 1006. The blades 1002 are linked with the connecting plate 1004 through the rocker arm 1003, and the tilt angle of multiple blades 1002 can be adjusted synchronously to change the airflow direction of the air outlet 6.

[0026] Furthermore, a temperature sensor is installed inside the material chamber 3. The temperature sensor is electrically connected to the refrigeration unit and the fan 8 through the controller. Specifically, the temperature sensor collects the temperature data of the material chamber 3 in real time. After being transmitted to the controller, it is compared with the preset refrigeration temperature, which is usually around 5-15℃. The controller automatically adjusts the power of the refrigeration unit and the speed of the fan 8: when the temperature is higher than the set value, the cooling capacity is increased and the speed of the fan 8 is increased to accelerate heat exchange; after the temperature reaches the target, the energy consumption is reduced to the maintenance mode to achieve dynamic balance of temperature in the material chamber 3 and ensure that the die-cut parts are always below the adhesive curing temperature.

[0027] like Figure 4 As shown, the material rack 9 includes a bracket 901, on which support rods 902 are spaced apart. The ends of the support rods 902 are threadedly connected to retaining rings 903. Specifically, the bracket 901 serves as a basic support structure, and the spaced support rods 902 on it are used to prevent the rolls of material to be die-cut from slipping off the support rods 902, thus facilitating the uniform flow of cold air between the rolls and achieving efficient pre-cooling. The retaining rings 903 at the ends of the support rods 902 are threadedly connected to block the rolls of material to be die-cut on the support rods 902, effectively preventing the rolls of material to be die-cut from slipping off the support rods 902 during placement and removal.

[0028] like Figure 4 As shown, a spacer ring 904 is fitted on the support rod 902. Specifically, the spacer ring 904 is fitted between two adjacent rolls of material to be die-cut during use, thereby separating them and ensuring that each roll of material can be fully exposed to cold air on all sides, achieving uniform pre-cooling and improving the pre-cooling effect; it can also reduce the risk of surface damage caused by the contact and compression of the rolls.

[0029] In practical use, during pre-cooling, the roll material to be die-cut is first sealed with a packaging bag to prevent moisture from seeping in. Then, it is placed on the material rack 9 and the box door is closed. Subsequently, the refrigeration unit is started, and the refrigerant is delivered to the evaporator. The refrigerant evaporates and absorbs heat in the evaporator, thereby reducing the temperature of the air in the refrigeration chamber 2. Then, the fan 8 is started, driving the cold air in the refrigeration chamber 2 to enter the material chamber 3 from the air outlet 6 at the upper end of the partition 4, and to process the die-cut parts on the material rack 9. After passing through the material chamber 3, the low-temperature airflow returns to the refrigeration chamber 2 from the return air outlet 7 at the lower end of the partition 4, forming a closed loop to achieve pre-treatment refrigeration of the die-cut parts.

[0030] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
