Description

Technical Field

[0001] This utility model relates to the field of running belt production equipment, and in particular to a molding device for producing patterned running belts. Background Technology

[0002] In the fitness equipment industry, the treadmill belt, as a core component of the treadmill, directly impacts the user experience and safety. To improve the anti-slip performance and aesthetics of the treadmill belt, creating specific patterns on its surface is a common and effective method. These patterns, with their textured design, significantly increase the friction between the treadmill belt and the soles of the runner's shoes, effectively reducing the risk of slipping and falling during running, thus providing a safer and more stable exercise environment.

[0003] Currently, the printing of patterns on treadmill belts mainly employs four methods: thermoforming, pad printing, hot stamping, and mold pressing. Thermoforming technology primarily involves heating and softening components to bring the surface of the treadmill belt to a suitable temperature. Combined with pressure applied by the printing rollers, the pattern, engraved with anti-slip embossing, is completely transferred onto the treadmill belt. This technology utilizes the synergistic effect of temperature and pressure to create a strong bond between the pattern and the belt body, ensuring pattern clarity and abrasion resistance.

[0004] However, in existing technologies, after the pattern is printed, the running belt is usually cooled naturally before entering the winding process or directly enters the winding process, lacking an effective rapid cooling and shaping mechanism. Because the surface temperature of the running belt is relatively high after the pattern is printed, it is in a relatively soft state. If it is not cooled in time, the pattern is easily affected by the stress generated by the movement of the running belt itself and external environmental factors (such as changes in temperature and humidity) during the subsequent movement and winding process, which can lead to deformation, blurring, or displacement. Utility Model Content

[0005] The purpose of this invention is to provide a molding device for producing patterned running belts, so as to solve the technical problem in the prior art that the running belt lacks an effective rapid cooling and shaping mechanism after the pattern is printed, which easily affects the quality and aesthetics of the running belt pattern.

[0006] To solve the above problems, the present invention provides a forming device for producing patterned running belts, which adopts the following technical solution: it includes a frame, and further includes a front conveyor roller group, a heating and softening component, a printing roller group, a cold air jet component, and a rear conveyor roller group arranged sequentially along the running belt traveling direction;

[0007] The front conveyor roller assembly includes at least two first drive rollers;

[0008] The heat-softening component is used to heat and soften the surface of the running belt, making it more receptive to embossing.

[0009] The printing roller assembly includes a printing roller with anti-slip embossed texture on its surface and a back pressure roller that presses against the printing roller.

[0010] The cold air jet assembly is used to rapidly cool the surface of the running belt and solidify the pattern.

[0011] The rear conveyor roller group includes at least two second drive rollers, and the rear conveyor roller group is driven synchronously with the front conveyor roller group.

[0012] Furthermore, the cold air jet assembly includes a refrigeration system and an air knife. The refrigeration system is connected to the air inlet of the air knife, and the air outlet of the air knife is located above the running belt.

[0013] Furthermore, a guide frame is provided on the frame, and the front conveyor roller group also includes a tension roller. The tension roller is slidably mounted on the guide frame in the vertical direction. The tension roller is linked to a force-applying element to balance the tension of the running belt. The force-applying element is a pneumatic cylinder or a spring.

[0014] Furthermore, the heating and softening assembly includes a heating chamber, a fan, and a heater. The fan is fixed to the top of the heating chamber, and the heater is installed above the treadmill belt and corresponds to the fan.

[0015] Furthermore, the heated chamber includes an inlet and an outlet for the treadmill belt to enter and exit, both of which are equipped with curtains.

[0016] Furthermore, the heating and softening component also includes infrared auxiliary heating tubes, which are distributed in multiple sets along the length of the running belt, and the length of the infrared auxiliary heating tubes is greater than the width of the running belt.

[0017] Furthermore, the anti-slip embossing depth of the printing roller is 0.5–1.2 mm, the sidewall inclination angle of the anti-slip embossing is greater than 70°, and the surface of the printing roller is plated with a hard chrome layer.

[0018] Furthermore, the surfaces of both the back pressure roller and the printing roller are coated with an anti-sticking layer.

[0019] Furthermore, the air outlet of the air knife is designed as a flat slit structure.

[0020] Furthermore, the air blades include two sets, which are located above and below the running belt, respectively, and the air outlets of the two sets of air blades are opposite each other.

The running belt goes through processes such as conveying, heating and softening, printing, and cooling and shaping in the device in sequence. There is no need for frequent transfer or adjustment, which can effectively reduce the downtime and waiting time in the production process and improve production efficiency.

[0023] 2. The cold air jet assembly sprays cold air onto the surface of the running belt, which can quickly reduce the surface temperature of the running belt, so that the pattern can be quickly fixed, ensuring the shaping effect of the pattern and improving the quality stability of the product.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0037] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0038] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0039] This utility model provides a molding device for producing patterned running belts, such as... Figures 1 to 3 As shown, it includes a front conveyor roller group 1, a heating and softening component 2, a printing roller group 3, a cold air jet component, and a rear conveyor roller group arranged sequentially along the traveling direction of the running belt 7.

[0040] In this embodiment, the front conveyor roller group 1 includes at least two first drive rollers 11, which are used to actively drive the running belt 7 forward. In this embodiment, a guide frame 12 is provided on the frame 6, and the front conveyor roller group 1 also includes a tension roller 13. The tension roller 13 is slidably mounted on the guide frame 12 in the vertical direction. The tension roller 13 is linked to a force-applying element 14, which can apply force to move the tension roller 13 on the guide frame 12, thereby balancing the tension of the running belt 7 during the conveying process, ensuring that the running belt 7 is conveyed smoothly and evenly, and avoiding problems such as the running belt 7 running off-center or deforming due to uneven tension.

[0041] In this embodiment, the force-applying element 14 is either a pneumatic cylinder or a spring. The pneumatic cylinder has the characteristics of fast response speed and high control precision, and can quickly adjust the position of the tension roller 13 according to the change of tension of the running belt 7; the spring has the advantages of simple structure and low cost, and can provide a stable elastic force to balance the tension of the running belt 7.

[0042] It should be noted that "the force-applying element 14 can apply force to move the tension roller 13 on the guide frame 12, thereby balancing the tension of the running belt 7 during the transmission process" is existing technology. Those skilled in the art should be clear about its structure, principle and usage, etc., and will not be described in detail here.

[0043] In this embodiment, the rear conveyor roller group includes at least two second drive rollers 5. The rear conveyor roller group is driven synchronously with the front conveyor roller group 1 to ensure that the running belt 7 is conveyed smoothly and continuously throughout the entire forming device, avoiding problems such as stretching, deformation or accumulation of the running belt 7 caused by inconsistent front and rear conveying speeds, thereby ensuring the production quality of the patterned running belt 7.

[0044] In other embodiments, the rotation of the first drive roller 11 and the second drive roller 5 can be achieved by a motor, and their surfaces can be covered with a high-friction material or engraved to increase traction.

[0045] In this embodiment, the function of the heating and softening component 2 is to heat and soften the surface of the running belt 7, making it easier to accept imprints. In this embodiment, the heating and softening component 2 includes a heating chamber 21, a fan 22, and a heater 23. The fan 22 is fixed to the top of the heating chamber 21, and the heater 23 is installed above the running belt 7 and corresponds to the fan 22. The fan 22 blows the heat generated by the heater 23 evenly onto the surface of the running belt 7 to achieve the purpose of heating and softening.

[0046] In this embodiment, the heating chamber 21 includes an inlet 211 and an outlet 212 for the treadmill belt 7 to enter and exit. Both the inlet 211 and the outlet 212 are equipped with curtains 213, which can effectively reduce heat loss and improve heating efficiency.

[0047] In this embodiment, the heater 23 is a PTC ceramic heater 23. The PTC ceramic heater 23 has advantages such as automatic temperature control, high thermal efficiency, and safety and reliability. It can quickly heat the air to the required temperature and maintain a stable temperature. In this embodiment, the fan 22 and the heater 23 are integrated into a drawer-type module for convenient and quick maintenance and replacement.

[0048] In this embodiment, the heating and softening component 2 further includes infrared auxiliary heating tubes 24. Multiple sets of infrared auxiliary heating tubes 24 are distributed along the length of the running belt 7, and the length of each infrared auxiliary heating tube 24 is greater than the width of the running belt 7. Multiple sets of infrared auxiliary heating tubes 24 can heat the running belt 7 from different positions, further improving the uniformity and efficiency of heating the running belt 7, ensuring that the surface of the running belt 7 is sufficiently softened, and providing favorable conditions for subsequent printing processes.

[0049] In this embodiment, the printing roller group 3 includes a printing roller 31 with anti-slip embossed texture 311 engraved on its surface and a back pressure roller 32 that presses against the printing roller 31. When the running belt 7 passes between the printing roller 31 and the back pressure roller 32, the anti-slip embossed texture 311 on the printing roller 31 will imprint the pattern on the surface of the running belt 7 under pressure.

[0050] In this embodiment, the anti-slip embossed texture 311 of the printing roller 31 has a depth of 0.5–1.2 mm, which can improve the wear resistance of the texture while ensuring its clarity. The sidewall inclination angle of the anti-slip embossed texture 311 is greater than 70°. A larger sidewall inclination angle makes it easier for the texture to be demolded during the printing process, reducing burrs and deformation at the edges of the texture and improving the quality of the texture. The surface of the printing roller 31 is plated with a hard chrome layer 312. The hard chrome layer 312 has advantages such as high hardness, good wear resistance, and strong corrosion resistance, which can extend the service life of the printing roller 31 and ensure the stability of printing quality.

[0051] In this embodiment, the surfaces of the back pressure roller 32 and the printing roller 31 are both coated with an anti-stick layer 33. The anti-stick layer 33 can prevent the running belt 7 from sticking to the printing roller 31 and the back pressure roller 32 during the printing process, avoiding defects such as scratches and damage on the surface of the running belt 7, and also facilitating the smooth transport of the running belt 7 and the complete imprinting of the pattern.

[0052] In this embodiment, the function of the cold air jet assembly is to rapidly cool the surface of the treadmill belt 7, thereby solidifying the pattern. In this embodiment, the cold air jet assembly includes a refrigeration system (not shown in the figure) and an air knife 4. The refrigeration system is connected to the air inlet of the air knife 4, and the refrigeration system generates low-temperature cold air and delivers it to the air knife 4. The air outlet of the air knife 4 is located above the treadmill belt 7, and the air outlet of the air knife 4 is configured as a flat, narrow slit structure.

[0053] It should be noted that the refrigeration system is existing technology, and those skilled in the art should be clear about its structure, principle and usage, etc., which will not be described in detail here.

[0054] In this embodiment, the air blades 4 include two sets, which are located above and below the running belt 7 respectively, with their air outlets facing each other. The two sets of air blades 4 simultaneously cool the running belt 7, enabling the upper and lower surfaces of the running belt 7 to cool down rapidly at the same time, further improving the shaping effect of the pattern and ensuring the quality of the patterned running belt 7.

[0055] The present invention provides a forming device for producing patterned running belts 7. In use, firstly, the running belt 7 to be processed is placed on the front conveyor roller group 1, and the drive rollers of the front and rear conveyor roller groups are started to make the running belt 7 move forward; secondly, the running belt 7 enters the heating and softening component 2 area, and the fan 22 draws air into the heating chamber 21. After being heated by the heater 23 and the infrared auxiliary heating tube 24, the hot air is evenly blown from the air outlet onto the surface of the running belt 7, causing the surface of the running belt 7 to be rapidly heated and softened; thirdly, the softened... The running belt 7 enters the printing roller group 3. Under the pressure of the printing roller 31 and the back pressure roller 32, the anti-slip embossed texture 311 on the surface of the printing roller 31 imprints the pattern onto the surface of the running belt 7. Then, the running belt 7 with the pattern imprinted enters the cold air jet assembly area. The low-temperature cold air generated by the refrigeration system is blown onto the upper and lower surfaces of the running belt 7 in a high-speed and uniform airflow form through the air knife 4, so that the surface of the running belt 7 is cooled quickly, the pattern is shaped and solidified. Finally, the cooled and shaped running belt 7 continues to be conveyed forward through the rear conveyor roller group to complete the entire forming process.
