Description

Technical Field

[0001] The utility model relates to the technical field of belt tension adjustment, in particular to a driving device with a belt tension adjustment mechanism for cutting. Background Technique

[0002] A belt is generally made of materials such as rubber and can be used as a driving component of a pulley. However, after long-term use, due to the action of its own toughness, the belt will gradually stretch, resulting in problems such as pulley slipping and reduced conveying efficiency.

[0003] When adjusting the tightness of the belt with the existing tension pulley, the operation is complex and the structure is redundant. Usually, the tension pulley directly bears the extrusion force from the belt. However, when the driving device that pushes the tension pulley to move has an unbalanced mechanical structure itself, this may cause the tension pulley that has been squeezed for a long time to become loose again.

[0004] Based on this, a driving device with a belt tension adjustment mechanism for cutting is proposed. Content of the Utility Model

A belt is arranged between the second pulley, the first pulley and the tensioning pulley. A protective cover is arranged on the outer side of the belt.

[0010] As a further improvement of the above solution, the gear driving mechanism includes a motor unit fixedly connected inside the cutting table. A driving gear is fixedly connected to the output end of the motor unit. The driving gear meshes with the driven gear.

[0011] As a further improvement of the above solution, the limit rod mechanism includes a clamping groove penetratingly formed on the fixing plate. A rod fixedly connected to one side of the crank connecting plate is movably connected inside the clamping groove.

[0024] Next, in combination with the attached drawings and specific implementation modes, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0025] Embodiment:

[0026] Please combine with Figures 1 - 7 , A driving device for cutting with a belt tension adjusting mechanism in this embodiment includes a cutting table 1. Fixed plates 2 are fixedly connected to both sides of the cutting table 1. A limiting roller 14 is rotatably connected to one side of the fixed plate 2. A crank connecting plate 17 is rotatably connected to the outside of the limiting roller 14. A tension pulley 7 is rotatably connected to the upper end of the crank connecting plate 17. The tension pulley 7 is made of composite rubber. An elastic tightening adjusting mechanism is arranged at the lower end of the crank connecting plate 17. A belt transmission mechanism is arranged on one side of the tension pulley 7. A limiting clamping rod mechanism is arranged on the side of the crank connecting plate 17 close to the fixed plate 2.

[0027] It should be particularly noted that as Figure 6 shown, the crank connecting plate 17 is an arc-shaped structure and is made of cemented carbide. The length of the lower swing arm is slightly greater than that of the upper swing arm, and the torque effect can be amplified through the lever principle.

[0028] Please combine with Figure 6 shown, the elastic tightening adjusting mechanism includes a pushing plate 18 fixedly connected to the lower end of the crank connecting plate 17. A vertical plate 9 is fixedly connected to one side of the fixed plate 2 close to the crank connecting plate 17. A threaded rod 10 is threadedly sleeved on the vertical plate 9. One end of the threaded rod 10 abuts against the pushing plate 18. An internal thread cap is arranged at the other end of the threaded rod 10, which is convenient for the cooperation of tools.

[0029] Please combine with Figure 4As shown in the figure, the belt drive mechanism includes a driven gear 12 rotatably connected to the fixed plate 2. An installation plate 4 is provided on the outer side of the driven gear 12. The lower side of the installation plate 4 is fixedly connected to the lower side of the fixed plate 2. A first pulley 5 is fixedly connected to the outer side of the driven gear 12, and a transmission component is arranged on the first pulley 5.

[0030] Please refer to Figure 4 As shown in the figure, the transmission component includes a second pulley 8 fixedly connected to the side of the limit roller 14 close to the first pulley 5. A belt 6 is arranged between the second pulley 8, the first pulley 5 and the tension pulley 7. A protective cover 3 is arranged on the outer side of the belt 6. A gear drive mechanism for driving the driven gear 12 to rotate is arranged on one side of the driven gear 12.

[0031] Please refer to Figure 4 , the gear drive mechanism includes a motor unit 13 fixedly connected inside the cutting table 1. The output end of the motor unit 13 is fixedly connected with a driving gear 11. The driving gear 11 meshes with the driven gear 12, and the motor unit 13 drives the belt 6 to transmit power.

[0032] Please refer to Figure 7 As shown in the figure, the limit clamping rod mechanism includes a clamping groove 16 penetratingly opened on the fixed plate 2. A clamping rod 15 fixedly connected to one side of the crank connecting plate 17 is movably connected inside the clamping groove 16. By restricting the clamping rod 15 through the clamping groove 16, the stability of the crank connecting plate 17 during the rotation and swing of the tension pulley 7 can be increased, making the tensioning effect better.

[0033] The implementation principle of a driving device with a belt tensioning and adjusting mechanism for cutting in the embodiment of the present application is as follows: When the motor unit 13 is started, it drives the driving gear 11 to rotate. Through meshing, it pushes the driven gear 12 to rotate. The rotation of the driven gear 12 drives the first pulley 5 to rotate. Through the belt 6, it drives the second pulley 8 to rotate. Since the tension pulley 7 is located inside the belt 6, by rotating the threaded rod 10, one end of the threaded rod 10 pushes the push plate 18 to rotate. The push plate 18 drives the crank connecting plate 17 to rotate, driving the tension pulley 7 to swing outward to achieve the effect of tightening the belt 6.

[0034] The above implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
