Description

Technical Field

[0001] This utility model relates to the technical field of pearl cotton processing equipment, specifically to a double-sided, double-station bonding machine. Background Technology

[0002] EPE (Expanded Polyethylene) foam, as a new type of environmentally friendly packaging material, is widely used in many fields. During the production and processing of EPE foam, two sheets are often bonded together to meet different usage requirements, such as making EPE foam sheets and irregularly shaped packaging.

[0003] Traditional double-station EPE foam bonding machines typically use plate-type heating devices to heat one side of the EPE foam before bonding it to another piece. However, this traditional bonding method has significant drawbacks. First, the plate-type heating devices require a large size to ensure sufficient heating area for the EPE foam, which not only occupies a lot of space but also increases equipment cost and energy consumption. Second, the EPE foam remains stationary during the heating process, making the entire bonding process incompatible with assembly line production, hindering smooth operation of the production line, and severely impacting production efficiency. Utility Model Content

[0027] In this embodiment, as a preferred technical solution, elastic positioning plates 10 are fixedly provided on the upper surface of the workbench 1 and on both sides of the discharge end of the belt conveyor 2. The elastic positioning plates 10 are inclined towards the center of the belt conveyor 2. The elastic positioning plates 10 are made of rubber.

[0028] In this embodiment, as a preferred technical solution, the spring telescopic assembly 4 includes a cavity 11 fixedly disposed on the upper surface of the workbench 1. A vertical rod 12 is inserted and connected inside the cavity 11. A limiting plate 13 is fixedly disposed at one end of the vertical rod 12 that extends into the cavity 11. A spring 14 is disposed between the limiting plate 13 and the bottom surface inside the cavity 11. A bearing seat 15 for connecting the heating roller 5 is fixedly disposed at the upper end of the vertical rod 12.

[0029] It should be noted that the belt conveyor 2 is an existing mature technology that is widely used in the processing and production of pearl cotton. It typically includes belt rollers, motors, and belts. Because its technology is mature and widely used, it will not be described in detail in this embodiment.

[0030] The working principle of this double-sided, double-station bonding machine is as follows: The machine uses a belt conveyor 2 to transport the lower layer of pearl cotton. A heating roller 5, supported by a spring-loaded telescopic assembly 4, heats the lower layer of pearl cotton. Simultaneously, a slotted frame 6 guides the upper layer of pearl cotton, ensuring it contacts the heated lower layer. Then, an electric push rod 7 pushes the pressure roller 9 in the pressure roller assembly downwards, compressing and bonding the upper and lower layers of pearl cotton, thus achieving efficient bonding. Throughout the process, all components work together, ensuring assembly-line production and improving efficiency. The double-station design allows the machine to process two pearl cotton workpieces simultaneously, further enhancing overall efficiency. Furthermore, the elastic positioning plate 10 on the worktable 1 helps center the pearl cotton, preventing displacement during transport and processing, ensuring accurate bonding, and further improving product quality.

[0031] The working process of this double-sided, dual-station bonding machine is as follows:

[0032] 1. Preparation Stage: First, connect the equipment to the power supply, so that the electric heating wire inside the heating roller 5 is connected to the external power supply through the conductive slip ring 17 to begin preheating the heating roller 5 until the set working temperature is reached. At the same time, start the belt conveyor 2 and adjust its conveying speed to the appropriate working parameters to prepare for conveying the lower layer of pearl cotton.

[0033] 2. Lower Layer EPE Cotton Conveying and Heating: The lower layer EPE cotton is placed on the belt conveyor 2, which carries and conveys it into the worktable 1. When the lower layer EPE cotton reaches below the heating roller 5, the spring telescopic component 4 automatically adjusts the height of the heating roller 5 according to the thickness of the EPE cotton, ensuring close contact between the heating roller 5 and the lower layer EPE cotton for heating. At this time, the electric heating wire inside the heating roller 5 heats up evenly, transferring heat to the surface of the lower layer EPE cotton to reach a suitable bonding temperature.

[0034] 3. Upper layer pearl cotton conveying and bonding: The upper layer pearl cotton is passed through the slot frame 6, so that it is positioned above the heating roller 5 and initially aligned with the lower layer pearl cotton that is being heated. After the upper layer pearl cotton is bonded to the lower layer pearl cotton at the end, it moves together with the lower layer pearl cotton.

[0035] 4. Extrusion and Bonding Stage: As the initially bonded pearl cotton continues to move forward to below the pressure roller assembly, the electric push rod 7 is activated, pushing the U-shaped frame 8 downwards, thereby causing the pressure roller 9 to press tightly onto the upper and lower layers of pearl cotton. As the pearl cotton continues to be conveyed, the pressure roller 9 extrudes the pearl cotton under a certain pressure, making the bond between the upper and lower layers of pearl cotton stronger and ensuring bonding quality.

[0036] 5. Material Discharge and Dual-Station Operation: After being pressed and bonded by the pressure roller 9, the pearl cotton continues to move forward under the drive of the belt conveyor 2 and is output from the discharge end on the other side of the worktable 1, completing the bonding process of one station. Simultaneously, while the above operation is being performed at this station, the same operation can also be performed at another station. That is, the entire process from conveying, heating, bonding to extrusion and bonding of two pearl cotton workpieces can be carried out simultaneously, making full use of equipment resources, improving overall production efficiency, and achieving efficient dual-station operation.

[0037] 6. Centering and Anti-deviation of EPE foam: During the lower layer of EPE foam conveying, the elastic positioning plates 10 located on both sides of the discharge end of the belt conveyor 2 play a crucial role. Because the elastic positioning plates 10 are inclined towards the center of the belt conveyor 2 and made of rubber, they possess elasticity and guiding properties. When the EPE foam passes by, they exert a force towards the center, ensuring the EPE foam is centered and effectively preventing lateral deviation during conveying and processing. This guarantees the accurate processing position of the EPE foam at the heating roller 5 and pressure roller 9, thereby improving the overall quality of the product and the stability of the bonding effect.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
