Description

Technical Field

[0001] The utility model relates to the field of baling machines, in particular to a protective cover structure of a baling machine. Background Art

[0002] An electric strapping machine is a strapping machine that uses electric tightening, friction buckling, and automatic cutting to tie the strap. After wrapping the plastic-steel or plastic strapping tape around the object from top to bottom, the joint is placed into the machine's working slot. The motor drives the tensioning wheel to tighten the strap, and the friction block is driven back and forth to form a friction buckle, bonding the straps. Finally, the strap is automatically cut.

[0003] However, in the actual process of achieving bonding and fixing by frictional heat generation, since the strapping tape is driven to continuously move sideways to generate frictional heat, the strapping tape may easily tilt sideways during actual use, which will ultimately affect the welding effect. Utility Model Content

[0004] In order to further reduce the side tilt of the strapping tape during welding, the present application provides a strapping machine cover structure.

[0005] This application provides the following technical solutions:

[0006] A protective cover structure for a baling machine comprises a protective cover body. A blocking portion for laterally blocking a baling belt extends from the bottom of the protective cover body, and a mounting hole for mounting and connection is provided on the protective cover body.

[0007] Optionally, a pad is detachably mounted on the side of the blocking portion facing the strapping tape.

[0008] Optionally, the backing plate and the blocking portion are fixed via screws, and the blocking portion is integrally provided with the protective cover body.

[0009] Optionally, the protective cover body is used to be installed and fixed on a corresponding tension wheel of the baler, and the protective cover body covers the tension wheel.

[0010] Optionally, an auxiliary guard strip is further included, which is located on one side of the protective cover body. The auxiliary guard strip has an extension portion at one end away from the protective cover body, and the extension portion avoids the friction block of the baler. The extension portion has an inwardly bent abutting end at one end away from the auxiliary guard strip, and the abutting end is used to abut the side wall of the baling belt.

[0011] Optionally, a movable guard bar is further included, which is located on one side of the protective cover body. One end of the movable guard bar is rotatably connected to the baler, and the other end of the movable guard bar is used to laterally block the baling belt.

[0012] Optionally, a return torsion spring is provided at the rotation connection of the movable guard bar to drive it to rotate and reset, one side of the movable guard bar abuts against the protective cover body, and the return torsion spring drives the movable guard bar to rotate and reset toward the protective cover body.

[0013] Optionally, the center of the protective cover body has an inwardly concave portion.

[0014] Optionally, the auxiliary guard strip is detachably connected to the baler via fasteners.

[0015] Optionally, the abutting end of the auxiliary guard strip has a limiting portion extending downward, and the limiting portion is used to abut against the side wall of the baler.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. The blocking part at the bottom of the protective cover body blocks the middle part of the strip strapping tape laterally. The auxiliary guard strip and the movable guard strip block the front and rear ends of the strapping tape laterally, effectively limiting the angle deflection of the strapping tape. This prevents the strapping tape from tilting during the tightening and welding process, ensuring the final welding and fixing effect.

[0018] 2. The pad and the blocking part are detachably connected. In actual use, pads of different thicknesses can be replaced as needed to meet the needs of more occasions and improve practicality;

[0019] 3. The movable guard strip moves in conjunction with the protective cover body under the action of the reset torsion spring. When the strapping tape needs to be placed horizontally and laterally, the movable guard strip automatically rotates to make space after the protective cover body is removed, making it easier to place the strapping tape. After placement, the protective cover body returns to its original position and pushes the movable guard strip to rotate and reset, thus achieving synchronization between the movable guard strip and the protective cover body, which is more convenient and quick.

[0026] The following is combined with Figure 1-4 This application is described in further detail.

[0027] A baler cover structure, such as Figure 1-Figure 3 As shown, it includes a protective cover body 1, and a blocking portion 2 for laterally blocking the strapping tape is extended from the bottom of the protective cover body 1. An inwardly concave recess 3 is provided in the center of the protective cover body 1. The setting of the recess 3 can effectively improve the overall structural strength of the protective cover body 1. Mounting holes 4 for installation and fixation are also provided on the protective cover body 1. There are 4 mounting holes 4 and they are set through. In actual use, the protective cover body 1 is installed and fixed to the corresponding tensioning wheel of the baler 10 by installing screws 8 in the mounting holes 4. The tensioning wheel can be covered with the help of the protective cover body 1 to avoid exposure of the tensioning wheel to the outside, thereby improving safety in use. In this way, the protective cover body 1 is detachably connected, and can be disassembled and replaced in actual use. When the tensioning wheel needs to be replaced, it is only necessary to disassemble the protective cover body 1, and there is no need to disassemble the entire baler 10. The operation is simpler, more convenient and faster.

[0028] like Figure 1 and Figure 2 As shown, there is an outwardly protruding convex ring 5 at the center of the back side of the protective cover body 1 and a mounting groove 6 for the bearing to be installed is formed inside. The design of the convex ring 5 can further improve the structural strength on the one hand, and on the other hand, it can well meet the installation requirements of the bearing and improve the smoothness of the subsequent rotation of the tension wheel.

[0029] like Figure 1 and Figure 2 As shown, a pad 7 is detachably connected to the back of the protective cover body 1 corresponding to the blocking portion 2. The pad 7 is connected and fixed to the protective cover body 1 by screws 8. The side of the pad 7 away from the protective cover body 1 is used to abut against the strapping tape to block it laterally. By designing a detachable pad 7, pads 7 of different thicknesses can be replaced to adapt to strapping tapes of different widths in actual use, and strapping tapes of different specifications can all be well blocked, achieving good applicability.

[0030] like Figure 3 and Figure 4As shown, it also includes an auxiliary guard strip 9, which is used to be fixed on the main body 11 of the baler 10. The auxiliary guard strip 9 can be detachably connected with the help of screws 8. The baler 10 also includes a base 12. One end of the main body 11 is usually rotatably connected to the base 12 and can be lifted up. The tensioning wheel is rotatably connected to the main body 11. The above-mentioned protective cover body 1 is also fixedly installed on the main body 11 during installation. In this way, when the strapping tape needs to be placed, the main body 11 can be lifted up, so that the protective cover body 1 and the auxiliary guard strip 9 are lifted up, so that the strapping tape can be smoothly placed horizontally. Subsequently, the main body 11 is flipped down and reset. At this time, the protective cover body 1 and the auxiliary guard strip 9 can achieve lateral blocking.

[0031] like Figure 3 and Figure 4 As shown, the auxiliary guard strip 9 is located on one side of the protective cover body 1, and the auxiliary guard strip 9 has a complete extension portion 13 at one end away from the protective cover body 1. The extension portion 13 is bent to avoid the friction block 14 on the baler 10, and has an inward-bent abutting end 15 at the end of the extension portion 13 away from the auxiliary guard strip 9. The abutting end 15 is used to abut the strapping tape to prevent its lateral movement. With the help of the abutting end 15, the lateral blocking of the front end of the strapping tape can be achieved, further improving the blocking effect, and after the extension portion 13 is avoided, a certain protective effect is formed, avoiding the risk of direct contact between personnel and the friction block 14, thereby improving safety in use; in addition, a downward-extending limiting portion 16 is provided at the abutting end 15, and the limiting portion 16 is used to abut the side wall of the base 12, so as to achieve the horizontal limitation of the auxiliary guard strip 9, thereby improving the overall stability of the installation of the auxiliary guard strip 9, and preventing shaking and displacement.

[0032] like Figure 3 and Figure 4 When the cover body 1 is flipped down with the main body 11, the protective cover body 1 pushes the movable guard bar 17 to overcome the restoring force of the reset torsion spring 18 and move downward, thereby blocking the rear end of the strapping tape laterally with the help of the bottom end of the movable guard bar 17.

[0033] In this way, the blocking portion 2 at the bottom of the protective cover body 1 blocks the middle part of the strip-shaped strapping tape laterally, and the auxiliary protective strip 9 and the movable protective strip 17 are combined to block the front and rear ends of the strapping tape laterally, thereby effectively limiting the angular deflection of the strapping tape, so that the strapping tape will not tilt laterally during the tightening and welding process, thereby ensuring the final welding and fixing effect.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
