Abstract
Description
Technical Field
[0001] This utility model relates to a packaging equipment, and more particularly to a packaging belt feeding mechanism and a packaging machine. Background Technology
[0002] Strapping packaging machines are commonly used packaging equipment. When items need to be packaged, simply place them in the machine's work frame, and the machine will automatically wrap them with strapping. During operation, the strapping machine needs to release the strapping onto the conveyor belt. Currently, the strapping is typically released using an unwinding roller, which provides the outward propulsion force through friction between the roller and the strap. However, this feeding method is unstable, as slippage between the strapping and the unwinding roller can occur, leading to inaccurate strapping feeding and affecting the subsequent packaging quality. Therefore, a more stable mechanism for feeding the strapping is urgently needed to ensure the quality of the packaged items. Utility Model Content
[0003] The purpose of this utility model is to provide a packaging tape feeding mechanism and a packaging machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0004] The solution to the technical problem of this utility model is:
[0005] A packaging tape feeding mechanism includes: a base plate with a mounting frame connected to its top side; a guide plate connected to the mounting frame, wherein a guide channel extending along its length is formed in the guide plate, a lower opening communicating with the guide channel is provided on the bottom side of the guide plate, and a clearance hole is provided on the top side of the guide plate opposite to the lower opening; a tape feeding assembly disposed on the mounting frame, the tape feeding assembly having a rotatable tape feeding wheel, the top side of the tape feeding wheel being located within the lower opening; and a tape pressing assembly disposed on the mounting frame, the tape pressing assembly having a pressure roller that can elastically press downward against the tape feeding wheel through the clearance hole.
[0006] This technical solution has at least the following beneficial effects: When the packaging tape needs to be conveyed into the strapping packaging machine, the unwound packaging tape is first guided into the guide channel of the guide plate. The feeding roller in the feeding assembly abuts against the bottom side of the packaging tape from the lower opening, while the pressure roller in the pressing assembly abuts against the top side of the packaging tape from the clearance hole. The elastic downward pressure of the pressure roller keeps the packaging tape pressed downward. When the feeding roller rotates, it can drive the packaging tape to be fed outward along the guide channel. Since the pressure roller keeps the packaging tape pressed against the feeding roller, it can effectively reduce the phenomenon of slippage between the packaging tape and the feeding roller. In this way, the guide channel supports and limits the packaging tape, which helps to prevent the packaging tape from shifting due to gravity after being fed out, and plays a role in guiding the feeding. In addition, the pressure roller presses the packaging tape tightly onto the feeding roller, which improves the stability of feeding the packaging tape, thereby improving the packaging effect of the goods.
[0007] As a further improvement to the above technical solution, the pressure assembly includes a pressure frame, a spring, and a pressure plate. One side of the pressure frame is rotatably connected to the mounting frame, and the feed roller is rotatably connected to the mounting frame. The spring is disposed on the mounting frame, and the pressure plate is disposed at the bottom end of the spring. The pressure plate abuts against the other side of the pressure frame, and the spring has a tendency to press the pressure plate downward against the pressure frame. The pressure roller is mounted on the pressure frame. As the pressure frame rotates upward, the pressure roller can move upward away from the feed roller, or as the pressure frame rotates downward, the pressure roller can press downward against the feed roller. In order to maintain the state of the pressure roller pressing downward against the feed roller, the spring provides downward pressure on the pressure plate, so that the pressure plate keeps pressing the pressure frame downward, thus realizing that the pressure roller elastically presses down on the top side of the feed roller.
[0008] As a further improvement to the above technical solution, a fixing plate is formed on the mounting frame, and a screw hole is provided on the fixing plate. The pressing assembly also includes a screw rod, which is connected to the screw hole. A limit ring is connected to the screw rod at a position below the fixing plate. The bottom end of the screw rod extends into the spring. The pressing plate is slidably connected to the mounting frame in the vertical direction. Before use, the pressure of the pressing roller pressing the packaging tape against the feeding roller can be adjusted. Specifically, when the screw is rotated upward, it can drive the limit ring to move upward, which can reduce the downward pressure of the limit ring on the spring, thereby reducing the downward pressure of the pressing roller on the feeding roller. When the screw is rotated downward, it can drive the limit ring to move downward, which can increase the downward pressure of the limit ring on the spring, thereby increasing the downward pressure of the pressing roller on the feeding roller. Thus, the overall use is more flexible and convenient.
[0009] As a further improvement to the above technical solution, a handwheel is connected to the top of the screw. When it is necessary to rotate the screw, force can be applied to the handwheel, making it more convenient and improving the ease of rotating the screw.
[0010] As a further improvement to the above technical solution, the guide plate includes a plate body and limiting strips. The plate body is connected to the mounting frame, and the plate body is provided with the clearance holes. The limiting strips are horizontally spaced and connected to the bottom side of the plate body, forming a lower opening between the two limiting strips. Raised ribs are formed on opposite sides of the two limiting strips, and the guiding channel is formed between the two raised ribs and the plate body. When the packaging tape enters the guide plate, both sides of the packaging tape enter the position between the two raised ribs and the plate body, while the two limiting strips limit the packaging tape on the left and right sides respectively. This achieves vertical and horizontal limitation of the packaging tape during the conveying process, effectively reducing the phenomenon of tape deviation when loading to the target position and improving the stability of loading.
[0011] As a further improvement to the above technical solution, with one end of the plate as the feeding end, a guide surface is provided on the top side of the two protruding ribs near the feeding end, and the two guide surfaces extend downward at an inclination towards the feeding end. Because the two protruding ribs are inclined near the feeding end, the guide channel formed by the two ribs at the guide surface gradually increases in size near the feeding end, thus facilitating the introduction of the packaging tape into the guide channel and improving ease of use.
[0012] As a further improvement to the above technical solution, an upper discharge plate is connected to the top side of the end of the plate away from the feed end, and a lower discharge plate is connected to the bottom side of the two limiting strips away from the feed end. The upper discharge plate and the lower discharge plate form a discharge gap. In use, the limiting of the packaging tape at the guide channel can be relatively loose, while the packaging tape, after being fed out from the guide channel, enters the discharge gap formed by the upper and lower discharge plates, where the limiting of the packaging tape by the upper and lower discharge plates is more tight. In this way, the upper and lower discharge plates further guide the packaging tape to the target position, improving the accuracy of feeding the packaging tape to the target position.
[0013] As a further improvement to the above technical solution, both the upper and lower discharge plates can be flexibly deformed. The upper and lower discharge plates can be flexibly adjusted and deformed after applying external force as needed, thereby meeting different usage requirements such as adjusting the feeding position of the packaging tape and the degree of limiting the packaging tape.
[0014] As a further improvement to the above technical solution, the belt feeding assembly includes a drive motor connected to the mounting frame, which drives the belt feeding wheel. The drive motor, mounted on the mounting frame, provides rotational driving force to the belt feeding wheel, thereby enabling the belt feeding wheel to transport the packaging belt.
[0015] A packaging machine includes the aforementioned packaging belt feeding mechanism.
[0016] This technical solution has at least the following beneficial effects: Since the packaging machine is equipped with the aforementioned packaging tape feeding mechanism, the packaging tape is supported and limited by the guide channel during feeding and conveying, which helps to prevent the packaging tape from shifting due to gravity after being sent out, and also plays a guiding role in feeding. In addition, the pressure roller is used to press the packaging tape tightly onto the feeding roller, which improves the stability of feeding the packaging tape, thereby improving the packaging effect of the goods.

[0021] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connection relationships mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.
[0022] Reference Figure 1A packaging tape feeding mechanism includes: a base plate 1 with a mounting frame 11 connected to its top side; a guide plate 2 connected to the mounting frame 11, wherein a guide channel extending along its length is formed in the guide plate 2, a lower opening communicating with the guide channel is provided on the bottom side of the guide plate 2, and a clearance hole 21 is provided on the top side of the guide plate 2 opposite to the lower opening; a tape feeding assembly disposed on the mounting frame 11, wherein the tape feeding assembly has a rotatable tape feeding wheel 31, the top side of which is located in the lower opening; and a tape pressing assembly disposed on the mounting frame 11, wherein the tape pressing assembly has a pressure wheel 41 that can elastically press downward against the tape feeding wheel 31 from the clearance hole 21.
[0023] In this packaging tape feeding mechanism, when the packaging tape needs to be conveyed into the strapping packaging machine, the unwound packaging tape is first guided into the guide channel of the guide plate 2. The feeding roller 31 in the feeding assembly abuts against the bottom side of the packaging tape from the lower opening, while the pressure roller 41 in the pressure assembly abuts against the top side of the packaging tape from the clearance hole 21. The elastic downward pressure of the pressure roller 41 keeps the packaging tape pressed downward. When the feeding roller 31 rotates, it can drive the packaging tape to be fed outward along the guide channel. Since the pressure roller 41 keeps the packaging tape pressed against the feeding roller 31, it can effectively reduce the phenomenon of slippage between the packaging tape and the feeding roller 31. In this way, the guide channel supports and limits the packaging tape, which helps to prevent the packaging tape from shifting due to gravity after being fed out, and plays a guiding role in feeding. In addition, the pressure roller 41 presses the packaging tape tightly against the feeding roller 31, which improves the stability of feeding the packaging tape, thereby improving the packaging effect of the goods.
[0024] The pressure belt assembly is mainly used to provide downward elastic pressure to the pressure roller 41. It has various structural forms. For example, in this embodiment, the pressure belt assembly includes a pressure frame 42, a spring 43, and a pressure plate 44. One side of the pressure frame 42 is rotatably connected to the mounting frame 11, the belt feed roller 31 is rotatably connected to the mounting frame 11, the spring 43 is disposed on the mounting frame 11, the pressure plate 44 is disposed at the bottom end of the spring 43, the pressure plate 44 abuts against the other side of the pressure frame 42, and the spring 43 has a tendency to press the pressure plate 44 downward against the pressure frame 42. The pressure roller 41 is mounted on the pressure frame 42. As the pressure frame 42 rotates upward, the pressure roller 41 can move upward away from the feed roller 31. Alternatively, as the pressure frame 42 rotates downward, the pressure roller 41 can press downward against the feed roller 31. In order to maintain the pressure roller 41 pressing downward against the feed roller 31, the spring 43 provides downward pressure to the pressure plate 44, so that the pressure plate 44 keeps pressing the pressure frame 42 downward. In this way, the pressure roller 41 is elastically pressed down on the top side of the feed roller 31.
[0025] The top end of the spring 43 can be directly fixed to the mounting bracket 11. At this time, the spring 43 provides a fixed downward pressing force to the pressure frame 42 through the pressure plate 44. However, when feeding packaging machines with different thicknesses of materials, the required downward pressure is not the same. Therefore, in this embodiment, a fixing plate 45 is formed on the mounting bracket 11. The fixing plate 45 is provided with screw holes. The pressing belt assembly also includes a screw 46. The screw 46 is connected to the screw hole. A limit ring 47 is connected to the screw 46 at the position below the fixing plate 45. The bottom end of the screw 46 extends into the spring 43. The pressure plate 44 is slidably connected to the mounting bracket 11 in the vertical direction. Before use, the pressure of the pressure roller 41 pressing the packaging tape against the feed roller 31 can be adjusted. Specifically, when the screw 46 is rotated upward, the limiting ring 47 can be moved upward, which reduces the downward pressure of the limiting ring 47 on the spring 43, thereby reducing the downward pressure of the pressure roller 41 on the feed roller 31. When the screw 46 is rotated downward, the limiting ring 47 can be moved downward, which increases the downward pressure of the limiting ring 47 on the spring 43, thereby increasing the downward pressure of the pressure roller 41 on the feed roller 31. In this way, the overall use is more flexible and convenient.
[0026] Furthermore, a handwheel 48 is connected to the top of the screw 46. When it is necessary to rotate the screw 46, force can be applied to the handwheel 48, making it more convenient and improving the ease of rotating the screw 46.
[0027] As a further embodiment of the guide plate 2 structure, such as Figure 2 As shown, the guide plate 2 includes a plate body 22 and limiting strips 23. The plate body 22 is connected to the mounting frame 11. The plate body 22 is provided with clearance holes 21. The limiting strips 23 are horizontally spaced on the bottom side of the plate body 22, forming a lower opening between the two limiting strips 23. Raised ribs 24 are formed on opposite sides of the two limiting strips 23, forming a guide channel between the two raised ribs 24 and the plate body 22. When the packaging tape enters the guide plate 2, both sides of the packaging tape enter the position between the two raised ribs 24 and the plate body 22, while the two limiting strips 23 limit the packaging tape on the left and right sides respectively. This effectively limits the packaging tape's vertical and horizontal movement during conveying, reducing the deviation of the packaging tape when it reaches the target position and improving the stability of the feeding process.
[0028] Furthermore, with one end of the plate 22 as the feed end, the top sides of the two protruding ribs 24 near the feed end are provided with guiding surfaces 25, which extend downwards at an inclination towards the feed end. Because the two protruding ribs 24 are inclined near the feed end, the guiding channel formed by the two protruding ribs 24 at the guiding surfaces 25 gradually increases in size near the feed end, thus facilitating the introduction of the packaging tape into the guiding channel and improving ease of use.
[0029] In some embodiments, an upper discharge plate 26 is connected to the top side of the plate 22 away from the feed end, and a lower discharge plate 27 is connected to the bottom side of the two limiting strips 23 away from the feed end. The upper discharge plate 26 and the lower discharge plate 27 form a discharge gap. In use, the limiting of the packaging tape at the guide channel can be relatively loose, while the packaging tape, after being fed out from the guide channel, enters the discharge gap formed by the upper discharge plate 26 and the lower discharge plate 27, where the limiting of the packaging tape by the upper discharge plate 26 and the lower discharge plate 27 is more tight. In this way, the upper discharge plate 26 and the lower discharge plate 27 further guide the packaging tape to the target position, improving the accuracy of feeding the packaging tape to the target position.
[0030] In some embodiments, both the upper discharge plate 26 and the lower discharge plate 27 can be flexibly deformed. For example, both the upper discharge plate 26 and the lower discharge plate 27 are made of metal, in which case they can be bent to a certain extent. The upper discharge plate 26 and the lower discharge plate 27 can be flexibly adjusted and deformed after applying external force as needed, thereby meeting different usage requirements such as adjusting the feeding position of the packaging tape and the degree of limiting the packaging tape.
[0031] In some embodiments, the tape feeding assembly includes a drive motor 32 connected to the mounting frame 11, the drive motor 32 driving the tape feeding roller 31. The drive motor 32, mounted on the mounting frame 11, provides a rotational driving force to the tape feeding roller 31, thereby enabling the tape feeding roller 31 to feed the packaging tape.
[0032] A packaging machine includes the aforementioned packaging belt feeding mechanism.
[0033] Because the packaging machine is equipped with the aforementioned packaging tape feeding mechanism, the guide channel supports and limits the packaging tape during feeding and conveying, which helps prevent the packaging tape from shifting due to gravity after being sent out, and also plays a guiding role in feeding. In addition, the pressure roller 41 presses the packaging tape tightly onto the feed roller 31, improving the stability of feeding the packaging tape, thereby improving the packaging effect of the goods.
[0034] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
