Description

Technical Field

[0001] This utility model belongs to the field of packaging machine technology, and specifically relates to a novel tape storage device for packaging machines. Background Technology

[0002] Automatic baling machines (or strapping machines) are machines that can automatically bale materials. They are used in various waste paper plants, recycling companies, and other enterprises. They are suitable for baling and recycling waste paper, plastic straw, etc. They are equipment that improves labor efficiency, reduces labor intensity, saves manpower, and reduces transportation costs. Existing automatic baling machines usually include a tape storage mechanism.

[0003] For example, Chinese utility model patent with publication number "CN209258454U" discloses a strapping machine feeder, which includes an upright frame, a slide rail set on the frame, a lower roller that slides up and down along the slide rail and an upper roller fixed to the upper end of the frame. A counterweight is hung on the lower roller. It also includes a turntable for engaging the raw material tape reel and a clutch for braking the turntable. It also includes a control device for judging the position of the lower roller and controlling the clutch to brake or release. The upper roller and the lower roller are provided with several grooves for the strapping tape to be threaded through. The strapping tape passes from the turntable to the upper roller and is wound between the grooves of the upper roller and the lower roller. Finally, it is led out from the upper roller. By setting the lower roller that can slide up and down, the feeding strapping tape is kept in a taut state under the gravity of the lower roller and its counterweight while passing through the upper and lower rollers. This avoids the phenomenon of tape jumping and jamming caused by the tape rebounding in the feeding gap of the feeder during the strapping process.

[0004] The aforementioned strapping mechanism, by incorporating upper and lower rollers, avoids strapping jumps and jams caused by the rebound of the strapping during the feeding gap of the feeder. However, since the lower roller is slidably mounted on the slide rail, operators typically need to move the lower roller close to the upper roller and hold it in place throughout the entire process to prevent it from falling, only releasing it after the strapping is complete. This process is quite laborious. Furthermore, if the angle between the feeder and the strapping machine is different, the angle of the entire feeder needs to be adjusted so that the upper roller faces the strapping machine directly; otherwise, the edge of the strap groove will damage the strapping when it is pulled out. Its adaptability is poor, and the structure of the strapping mechanism needs further optimization.

[0005] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to the occurrence of this case. Summary of the Invention

[0006] The purpose of this utility model is to provide a new type of tape storage device for a packing machine that is simple in structure and highly adaptable.

[0007] To achieve the above objectives, this utility model adopts the following technical solution:

[0008] A novel strapping storage device for a packing machine includes a base frame, on which a vertically arranged connecting frame is fixed. A rotating shaft is rotatably connected to the upper part of the connecting frame, and a strapping disc wheel is fixedly mounted on the rotating shaft. A vertically arranged positioning frame is also provided on the base frame, and a braking assembly for braking the strapping disc wheel is also provided on the rotating shaft. A horizontally arranged mounting frame is fixed to the top of the positioning frame, and an upper strapping wheel assembly is fixed to the bottom of the mounting frame. A vertically arranged slide rail and a sliding block that can slide on the slide rail are fixed to the positioning frame. A lower strapping wheel assembly is fixed to the sliding block and is located below the upper strapping wheel assembly. A universal wheel assembly is rotatably mounted on the mounting frame, located at the end of the mounting frame away from the positioning frame. The universal wheel assembly includes universal wheels with traction grooves for threading the packing strap. A fixing hook is rotatably mounted on the side wall of the positioning frame, and a locking groove is provided on the side of the sliding block corresponding to the fixing hook for the fixing hook to engage.

[0009] Furthermore, the braking assembly includes a drum brake disc and a brake lever connected to the outside of the drum brake disc for controlling the movement of the drum brake disc. The drum brake disc is disposed between the pulley and the connecting frame. One end of the brake lever is a connecting end fixed on the drum brake disc, and the other end is a control end extending in the direction of the positioning frame.

[0010] Furthermore, the positioning frame has a slot on one side corresponding to the brake rod for the brake rod to extend into, and the control end of the brake rod extends into the slot.

[0011] Furthermore, the slide block is also provided with a pressure rod for pressing against the brake rod. The pressure rod is located on the slide block at a position corresponding to the control end of the brake rod, and the pressure rod is located above the brake rod.

[0012] Furthermore, the upper pulley assembly is provided with a plurality of upper grooves for threading the packing strap, the lower pulley assembly is provided with a plurality of lower grooves for threading the packing strap, the upper pulley assembly is provided with upper pressure rollers for pressing the upper grooves, and the lower pulley assembly is provided with lower pressure rollers for pressing the lower grooves.

[0013] Furthermore, the caster wheel assembly also includes a traction pressure roller for pressing the traction belt groove.

[0014] Furthermore, the bottom of the base frame is provided with several support feet for supporting the base frame, and the bottom of the support feet is provided with anti-slip rubber pads.

[0015] By adopting the aforementioned design scheme, the beneficial effects of this utility model are:

[0016] This novel tape storage device has a simple structure and is equipped with a fixing hook to support the slide and lower pulley assembly, preventing them from falling. This effectively reduces the workload of operators, saving effort and making it more user-friendly. Furthermore, because the universal wheel assembly can rotate freely in the horizontal direction, and the strapping is wound around the traction groove, the edge of the traction groove will not damage the strapping when it is pulled out from the universal wheel. Compared with the prior art, there is no need to adjust the position of the tape storage device to face the strapping machine, making it more adaptable.

[0017] Furthermore, an upper pressure roller for pressing the upper belt groove, a lower pressure roller for pressing the lower belt groove, and a traction pressure roller for pressing the traction belt groove are provided. These features can compact the packing strap within the upper belt groove, lower belt groove, and traction belt groove, preventing the strap from coming off due to accidental impacts and ensuring stable and reliable operation of the device.

[0018] Furthermore, the base frame, connecting frame, positioning frame, and mounting frame of this utility model are all detachable and connectable individual components, which can be shipped separately during transportation, thereby reducing transportation costs. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] like Figures 1 to 4As shown, a novel strapping device for a packing machine includes a base frame 11, which is horizontally arranged. A vertically arranged connecting frame 12 is fixed on the base frame 11. A rotating shaft 13 is rotatably connected to one side of the upper part of the connecting frame 12. A belt reel 14 is fixed on the rotating shaft 13. In this embodiment, the belt reel 14 can adopt a conventional belt reel structure for winding packing straps. A braking assembly 2 for braking the rotation of the belt reel 14 is also provided on the rotating shaft 13. The frame 11 is also equipped with a vertically arranged positioning frame 15. A horizontally arranged mounting frame 16 is fixed to the top of the positioning frame 15. An upper pulley assembly 3 is fixed to the bottom of the mounting frame 16. A vertically arranged slide rail 151 and a slide block 152 that can slide on the slide rail 151 are fixed to the positioning frame 15. The slide rail 151 extends from the lower part of the positioning frame 15 to the upper part near the mounting frame 16. A lower pulley assembly 4 is fixed to the slide block 152, located below the upper pulley assembly 3. Correspondingly, the upper pulley assembly 3 is provided with several upper grooves 31 for threading the packing strap, and the lower pulley assembly 4 is provided with several lower grooves 41 for threading the packing strap. The number and position of each upper groove 31 and each lower groove 41 correspond to facilitate the threading of the packing strap. A caster assembly is rotatably mounted on the mounting frame 16. The caster assembly is located at the end of the mounting frame 16 away from the positioning frame 15, and is positioned close to the upper pulley assembly 3. Correspondingly, the caster assembly... The components include a caster wheel 17, which has a traction groove 171 for the packing strap to pass through; a fixing hook 18 is rotatably provided on the side wall of the positioning frame 15, and a mounting groove 153 is provided on the side of the slide block 152 corresponding to the fixing hook 18 for the fixing hook 18 to engage. Specifically, one end of the fixing hook 18 is detachably mounted on the side wall of the positioning frame 15 by bolt fasteners, and the fixing hook 18 can be rotated or fixed by loosening or tightening the bolt fasteners.

[0040] This novel strapping device has a simple structure. Before use, the operator needs to pull the strapping from the pulley 14, loosen the bolts, and then push the slide 152 to move the lower pulley group 4 closer to the upper pulley group 3. When the slide 152 moves to the position close to the upper pulley group 3, the fixing hook 18 is rotated to the bottom of the locking groove 153, and then the bolts are tightened so that the fixing hook 18 engages with the locking groove 153, thereby supporting the slide 152 and the lower pulley group 4 to prevent them from falling. Then, the strapping is sequentially wrapped around the upper groove 31 of the upper pulley group 3 and the lower groove 41 of the lower pulley group 4. This effectively reduces... This design reduces the workload of operators, saving effort and is more user-friendly. After the strapping is wound, it is pulled out from the upper pulley group 3 and wound onto the universal wheel 17, and then pulled from the universal wheel 17 to the subsequent strapping machine. The universal wheel assembly is located near the upper pulley group 3, and the strapping is wound in the traction groove 171. Even if the strapping storage device is not directly facing the strapping machine, the universal wheel assembly can rotate freely in the horizontal direction, and the edge of the traction groove 171 will not damage the strapping when it is pulled out from the universal wheel. Compared with the existing technology, it is not necessary to adjust the position of the strapping storage device to face the strapping machine, which has better adaptability.

[0041] The braking assembly 2 of this utility model includes a drum brake disc 21 and a brake lever 22 connected to the outside of the drum brake disc 21 for controlling the drum brake disc 21 to achieve braking action. The drum brake disc 21 is mounted on the rotating shaft 13 and located between the disc wheel 14 and the connecting frame 12. One end of the brake lever 22 is a connecting end fixed on the drum brake disc 21, and the other end is a control end extending towards the positioning frame 15. Both the drum brake disc 21 and the brake lever 22 of this utility model can adopt the conventional structure of a drum brake with internal brake pads. When the brake lever 22 is in a horizontal state, the disc wheel 14 rotates normally. When the control end of the brake lever 22 is pressed down, the connecting end of the brake lever 22 rotates and drives the brake pads in the drum brake disc 21 to clamp the rotating shaft 13, thereby achieving braking. The greater the downward distance of the control end of the brake lever 22, the stronger the braking effect. The braking assembly 2 of this utility model can also adopt other conventional structures in the field, as long as they can achieve a braking effect on the disc wheel 14.

[0042] Furthermore, the positioning frame 15 has a slot on one side corresponding to the brake lever 22 for the brake lever 22 to extend into. The control end of the brake lever 22 extends into the slot. Correspondingly, the slide block 152 is also provided with a pressure rod 154 for pressing against the brake lever 22. The pressure rod 154 is located on the slide block 152 at the position corresponding to the control end of the brake lever 22, and the pressure rod 154 is located above the brake lever 22. In use, the roll with the packing strap is placed in the pulley 14. When packing, the packing strap is pulled by the packing machine. Pulling the packing strap will pull the lower pulley group 4 and the slide block 1 at the same time. 52 moves upward, so that the pressure rod 154 is always above the brake rod 22, and the belt pulley 14 can rotate normally. When the packing is completed, the packing machine stops driving the packing strap to move, so that the slide 152 and the lower pulley group 4 move downward under their own weight, so that the pressure rod 154 presses against the control end of the brake rod 22. The weight of the slide 152 will drive the pressure rod 154 to press down the control end of the brake rod 22, so that the brake rod 22 will brake the belt pulley 14, preventing the belt pulley 14 from continuing to rotate due to inertia after the packing is completed, which would cause the packing strap to become messy.

[0043] Furthermore, the upper pulley assembly 3 is equipped with an upper pressure roller 32 for pressing the upper belt groove 31. The upper pressure roller 32 is rotatably mounted on the upper pulley assembly 3 and located above the upper belt groove 31. The lower pulley assembly 4 is equipped with a lower pressure roller 42 for pressing the lower belt groove 41. The lower pressure roller 42 is rotatably mounted on the lower pulley assembly 4 and located below the lower belt groove 41. The universal wheel assembly is equipped with a traction pressure roller 172 for pressing the traction belt groove 171. The traction pressure roller 172 is rotatably mounted on the universal wheel assembly and located above the traction belt groove 171. This arrangement can firmly press the packing strap into the upper belt groove 31, lower belt groove 41, and traction belt groove 171, preventing the strap from coming off due to accidental impact and ensuring stable and reliable operation of the device.

[0044] Furthermore, the bottom of the base frame 11 is also provided with several support feet 19 for supporting the base frame 11. The bottom of the support feet 19 is provided with anti-slip rubber pads 191. This setting can play an anti-slip role and can prevent the base frame 11 from directly contacting the ground and causing wear.

[0045] Furthermore, the base frame 11, connecting frame 12, positioning frame 15, and mounting frame 16 of this utility model are all detachable and installable individual components, which can be shipped separately during transportation, thereby reducing transportation costs.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
