Description

Technical Field

[0001] This utility model belongs to the technical field of printing and packaging equipment, and relates to a heating device for a hot box gluing machine. Background Technology

[0002] A hot-melt box gluing machine is a specialized piece of equipment used in printing and packaging. Its working principle involves using hot melt adhesive to bond the seams of semi-finished boxes together, thus creating the finished box. The heating device in the machine quickly heats the hot melt adhesive to a specific temperature, achieving the effect of bonding the box pieces. To enable rapid molding of PE packaging boxes, the edges of the box pieces need to be heated or heat-sealed using activated polyethylene. For polyethylene (PE-LD), heating to approximately 115°C is required before sealing the box pieces.

[0003] Most existing heat sealing machines use eight Swiss heaters, each connected to a blower motor. Each heater requires individual airflow adjustment, resulting in slow heating efficiency and a production speed of only 110-140 m / min. Furthermore, poor heat uniformity during heating easily leads to low production efficiency and mismatched capacity. In addition, precise temperature control is problematic, and the operating costs are relatively high. Existing heat sealing machines also face difficulties in temperature control.

[0004] In summary, the heating devices of existing hot glue box machines have problems such as slow heating speed and difficulty in controlling heating temperature. Therefore, a new type of heating device is needed to solve some of the problems existing in the current heating devices. Utility Model Content

[0005] The purpose of this invention is to provide a heating device for a hot box gluing machine, which solves the problems of slow heating efficiency and difficulty in precise temperature control in the prior art.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 As shown, the heating device for the hot-pressed box machine of this utility model includes a wall plate 1 arranged opposite to each other, an adjusting screw 3 fixed inside the frame, a support shaft 2 perpendicular to the wall plate 1, and a heating support frame 9 movably connected to the support shaft 2. Several heating boxes 10, a moving plate 4, and a curved component 15 are fixed on the heating support frame 9. Several first transmission guide wheels 5 are fixed on the moving plate 4, and a downward pressure belt 6 is wound around the first transmission guide wheels 5. Several second transmission guide wheels 7 are fixed on the curved component 15, and an upper pressure belt 8 is wound around the second transmission guide wheels 7. A distance is left between the upper pressure belt 8 and the lower pressure belt 6 for the box pieces to pass through. The upper pressure belt 8 and the lower pressure belt 6 in this device are mainly used to transport the box pieces, ensuring that the box pieces move on the device, thereby completing the heating.

[0024] like Figure 2 As shown, the adjustment mechanism 11 includes multiple components such as a fixed back plate 111, an opening, a threaded hole, a screw 112, an elastic element, and a cylinder 113. The fixed back plate 111 is positioned opposite the heating support frame 9. The heating support frame 9 has an opening, and the fixed back plate 111 has a threaded hole at a corresponding position. A screw 112 is fitted into the opening, and the screw 112 is fitted with the threaded hole. An elastic element is sleeved on the screw 112. A cylinder 113 is also provided on the side of the heating support frame 9. Through this adjustment mechanism 11, the position of the heating box 10 can be adjusted, thereby achieving the adjustment of the heating temperature. The addition of the adjustment mechanism 11 makes the adjustment of the heating box 10 more precise, meeting different production needs and improving the automation level of the machine.

[0025] The heating boxes 10 are arranged in a row and parallel to the upper pressure belt 8 and the lower pressure belt 6. A heating support frame 9 is movably connected to the support shaft 2, and several heating boxes 10 are fixed on the heating support frame 9. Heating support frames 9 are provided on both sides of the moving plate 4, and a row of heating boxes 10 are fixed on the heating support frame 9 accordingly. The side of the heating box 10 with the air hole 102 faces the moving plate 4.

[0026] like Figure 3 As shown, the heating chamber 10 includes multiple components such as a main body 101, a heating core 104, air vents 102, and mounting feet 103. Specifically, the heating chamber 10 includes a main body 101, with air vents 102 on one side, mounting feet 103 fixedly connected to the bottom of the main body 101, and a heating core 104 on the top of the main body 101. The air vents 102 are arranged in a straight, multi-row pattern, with a spacing of 1.5mm between the vents. The heating chamber 10 primarily provides a heat source. The arrangement of the straight, multi-row air vents significantly increases the number of vents 102, enhancing the ventilation effect of the hot paste machine. This effectively reduces the temperature, prevents poor drying of the hot paste, improves heating efficiency, and ensures temperature uniformity.

[0027] A lower cooling water tank 12 is fixedly installed on the side of the transfer plate 4, and an upper cooling water tank 13 is fixedly installed above the lower cooling water tank 12. The addition of cooling water tanks can support the box sheets and also enable the temperature of the hot box gluing machine to be balanced in a timely manner during the production process, thus stabilizing the production quality.

[0028] A slide rail is fixed on the support shaft 2, and the slide rail is set parallel to the wall panel 1. A corresponding slider is set on the slide rail, and the slider is fixed to the bottom of the heating support frame 9. In case of abnormality, the heating box 10 can be quickly pushed out, away from the heating plate, to prevent the heating plate from burning and to ensure safety and reliability.

[0029] A tensioning wheel 14 is fixed to the curved component 15 parallel to the plane of the wall panel 1. The tensioning wheel 14 and the second transmission guide wheel 7 are on the same plane. The tensioning wheel 14 and the second transmission guide wheel 7 around the upper pressure belt 8 enable the belt to maintain normal operation. The addition of the tensioning wheel 14 allows the tension of the upper pressure belt 8 to be adjusted as needed, thus better ensuring the transmission effect.

[0030] A temperature controller is fixed inside the rack to monitor the temperature inside the rack.

[0031] The surface of the rack is equipped with a protective exhaust hood to ensure stable ambient temperature.

[0032] The implementation process of this utility model is as follows:

[0033] A support shaft 2 is perpendicularly fixed to the wall panel 1 to form a frame, and a heating support frame 9 is movably connected to the support shaft 2. Several heating boxes 10 are fixed on the heating support frame 9. The moving plate 4 is pressed downwards by a fixed first transmission guide wheel 5 and a lower pressure belt 6. A curved member 15 is fixed above the moving plate 4, and several second transmission guide wheels 7 are fixed on the curved member 15. An upper pressure belt 8 is wound around the second transmission guide wheels 7, and a distance is left between the upper pressure belt 8 and the lower pressure belt 6 for the box pieces to pass through. The moving plate 4 is driven by the first transmission guide wheel 5 and the lower pressure belt 6. Similarly, it is driven by the second transmission guide wheels 7 and the upper pressure belt 8, which causes the upper pressure belt 8 to work, causing the box pieces on it to move accordingly, and finally gluing the product together.

[0034] When the set temperature is reached, the heating chamber begins heating. Due to the use of straight multi-row air vents 102, heat can be fully conducted, thereby accelerating product heating and improving heating efficiency. The adjustment mechanism 11 is fixed to the bottom of the heating chamber 10 by a cylinder 113, and has the function of automatically adjusting the position of the heating chamber 10.

[0035] As an optimization, the heating chamber 10 can be heated electrically.

[0036] As an optimization, the temperature controller uses the Japanese brand Omron to ensure accuracy control within ±0.5°C, and the temperature control probe has a communication interruption alarm function to prevent continuous heating from burning out components.

[0037] As an optimization, the hot air gun head adopts a straight multi-row air hole 102 structure to ensure uniform and reliable hot air lines. It is equipped with infrared temperature measurement and displays it on the human-machine interface, which makes it easy to track the heat sealing effect and temperature at any time. The air supply system can adjust the air volume and pressure. The heating temperature control has a separate human-machine interface for adjustment and is linked with the main unit to prevent the paper from igniting even when the main unit stops heating the hot air.

[0038] As an optimization, the cooling water tank adopts high-pressure stainless steel refrigeration bright tubes and the refrigeration unit; a protective ventilation cover for the electric heating unit is designed to ensure uniform ambient temperature of this unit and smooth exhaust of hot air.

[0039] This technical solution improves heating efficiency by changing the heating method, significantly increasing the production efficiency of the hot-melt box gluing machine. The addition of an adjustment mechanism 11 allows for more precise adjustment of the heating chamber 10, meeting diverse production needs and enhancing the machine's automation level. The linear multi-row air vents 102 greatly increase their number, improving ventilation and effectively reducing temperature to prevent poor drying of the glue. The addition of a cooling water tank ensures timely temperature balance during production, stabilizing product quality. It significantly increases the heating speed, preventing product quality instability, while precisely controlling the heating temperature, thus improving both efficiency and product quality. Its practicality and economic benefits are evident, making it widely applicable and worthy of promotion.
