Description

Technical Field

[0001] This application relates to the field of material packaging, specifically to a rapid filling device for packaging bags. Background Technology

[0002] Automated packaging equipment for granular materials is widely used in e-commerce, logistics, and retail industries. This equipment precisely controls the amount of material fed at a time through a metering device in the upper hopper, with the material falling into the packaging bag below through the discharge port. Automated or semi-automated packaging devices play a crucial role in improving packaging efficiency and accuracy.

[0003] Currently, rapid packaging equipment for granular materials mainly completes the packaging process through a series of automated procedures. It typically includes components such as a hopper, metering device, bagging device, and sealing device. Its working principle is as follows: sensors detect the quantity of granular material; the metering device transfers the granular material to the hopper; upon receiving a signal, the hopper opens its outlet; and a clamping assembly fixes the packaging bag at the outlet position, allowing the granular material to enter the packaging bag through the outlet.

[0004] However, existing clamping components struggle to stably hold the packaging bag at the discharge port. During the filling process, the bag easily slips off, resulting in incomplete filling and wasted material. The inability of the clamping components to securely hold the bag at the discharge port reduces filling efficiency. Solving these technical problems is a challenge that those skilled in the art need to address. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a rapid filling device for packaging bags.

[0006] In one embodiment, the rapid filling device for packaging bags includes a hopper and a clamping assembly. The hopper includes a discharge port. The clamping assembly includes a first driving member and two clamping components, which are respectively disposed on both sides of the discharge port. Each clamping component includes a connecting member and an abutting member. The connecting member is movably connected to the hopper, and the abutting member is connected to the connecting member. The abutting member is configured to conform to the shape of the discharge port. The two connecting members are respectively drivenly connected to the first driving member. The first driving member drives the two abutting members to move closer to or further away from the discharge port via the two connecting members. The two abutting members abut or separate from the discharge port to fix or move the discharge port to the packaging bag.

[0007] Understandably, by setting two abutment members that can conform to the shape of the discharge port, and by having the first driving member synchronously drive the two abutment members to move closer or further away from the sides of the discharge port via two connecting members, the abutment members can abut or separate from the discharge port. By utilizing the shape matching between the abutment members and the discharge port, the stability of the packaging bag during the filling process is improved.

[0008] In one embodiment, the abutment includes a connecting clearance section and a clamping section. The clearance section is shaped to match the outer periphery of the discharge port, and the clamping section is connected to the clearance section and located on the side of the discharge port.

[0009] Understandably, the clearance section is designed to match the outer circumference of the discharge port, so that when the contact part approaches the discharge port, the clearance section can guide and close the bag opening, which is beneficial for the bag to align with the discharge port when it is close to the discharge port.

[0010] In one embodiment, the abutment includes a clearance section and two clamping sections, the two clamping sections being respectively connected to both sides of the clearance section.

[0011] Understandably, the rapid filling device for packaging bags includes two abutment members. After the two clearance sections fix the packaging bag to the discharge port respectively, a gap is left between the two clamping sections located on the same side of the two abutment members. This gap can prevent the operator from being pinched during the process of assisting in fixing the packaging bag.

[0012] In one embodiment, the clamping component further includes a seal, which is disposed on the side of the abutment member facing the discharge port. The seal includes a belt and a bumper block, with the belt disposed on the surface of the avoidance section and the bumper block disposed on the surface of the clamping section.

[0013] Understandably, the belt's elasticity and flexibility allow it to effectively fill tiny gaps when the clearance section fits tightly against the discharge port and the bag opening, improving the overall airtightness of the fixed area. Simultaneously, the belt also acts as a buffer, preventing the rigid clearance section from directly contacting the packaging bag and causing wear or damage. The anti-collision blocks, with their elasticity, prevent the clamping section from scratching operators when it comes into direct contact.

[0014] In one embodiment, the connector includes two first connecting handles, two second connecting handles, and a connecting rod. The bottom ends of the two first connecting handles are respectively connected to the same side of the abutment away from the hopper. The bottom ends of the two second connecting handles are respectively connected to the two ends of the connecting rod. The top ends of the two first connecting handles are respectively connected to the side wall of the connecting rod. The top ends of the two first connecting handles are hinged to the hopper.

[0015] Understandably, the design of the connector facilitates smooth transmission between the first and second connecting handles, ensuring high synchronization and precision between the two abutting parts during movement. Simultaneously, the connector design ensures that the abutting parts fix the bag opening at a constant angle and trajectory, enhancing the motion stability and operational reliability of the clamping assembly.

[0016] In one embodiment, the second connecting handle protrudes away from the hopper to avoid the hopper.

[0017] Understandably, the protrusion on the second connecting handle increases the distance between the second connecting handle and the hopper, preventing mechanical interference or collision between the second connecting handle and the hopper during swinging or operation. The protrusion on the second connecting handle 2212 reduces potential mechanical wear and jamming risks, ensuring the smoothness and reliability of the overall movement of the connecting parts and extending the service life of the components.

[0018] In one embodiment, the first connecting handle protrudes towards the direction of the hopper and is positioned close to the discharge port.

[0019] Understandably, the protrusion of the first connecting handle creates a configuration close to the hopper on one side. On one hand, the protrusion reduces the space occupied by the clamping components, which is beneficial for equipment integration and miniaturization; on the other hand, the protrusion optimizes the force transmission path of the abutment when fixing the bag opening, improving the fastening efficiency and reliability of the abutment on the bag.

[0020] In one embodiment, the tapping assembly includes tapping members and a third driving member. The tapping members are spaced apart at the bottom of the discharge port, and the third driving member is driven to connect with the tapping members to push the tapping members to extend towards the side where the discharge port is located.

[0021] Understandably, the beater component solves the problem in existing granular material packaging processes where some less free-flowing materials cannot fully fall into the bag. By beating the packaging bag with the beater component, the material can be effectively loosened, promoting smooth flow into the bag and preventing blockage. The beater component ensures that the granular material fills the packaging bag, improving the bag's utilization efficiency and facilitating faster packaging.

[0022] In one embodiment, the end of the striking member away from the third driving member is planar.

[0023] Understandably, a planar shape allows for a larger contact area between the striking component and the packaging bag surface, enabling the striking force to be transmitted and dispersed evenly. The planar shape also facilitates the breaking of bridging phenomena within the packaging bag, preventing excessive localized stress that could damage the bag, thus protecting it and enhancing the operational safety of the striking component.

[0024] In one embodiment, the packaging bag rapid filling device further includes a lifting component, which includes a fourth driving member, a hook, a fifth driving member, and a baffle. The fourth driving member is spaced apart on the side of the hopper and is vertically arranged. The hook is detachably connected to the bottom of the fourth driving member. The fourth driving member is used to lift and lower the hook along the direction of gravity. The baffle is detachably connected to the opening of the hook. The fifth driving member is used to drive the baffle to abut or separate from the opening of the hook.

[0025] Understandably, the clamping assembly is suitable for securing packaging bags with small or medium diameter openings, while the lifting assembly can secure large-diameter packaging bags. The baffle is detachably connected to the hook opening; the fifth drive unit drives the baffle to abut or separate from the hook opening, completing the gripping and release of the packaging bag opening by the hook. The lifting assembly expands the applicability of the rapid packaging bag filling device and improves the efficiency of securing packaging bags. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1 To be continued Figure 3 This application will be described in further detail below.

[0031] In one embodiment, the rapid filling device for packaging bags includes a hopper 1 and a clamping assembly 2. The hopper 1 includes a discharge port 11. The clamping assembly 2 includes a first driving member 21 and two clamping components 22, which are respectively disposed on both sides of the discharge port 11. Each clamping component 22 includes a connector 221 and an abutment 222. The connector 221 is movably connected to the hopper 1, and the abutment 222 is connected to the connector 221. The abutment 222 is configured to conform to the shape of the discharge port 11. The two connectors 221 are drivenly connected to the first driving member 21. The first driving member 21 drives the two abutments 222 to move closer to or further away from the discharge port 11 via the two connectors 221. The two abutments 222 abut or separate from the discharge port 11, thereby fixing or moving the discharge port 11 to the packaging bag.

[0032] In this embodiment, refer to Figures 1 to 3 The discharge port 11 is the channel for material flow. The discharge port 11 can be designed into a circular or other shape according to actual needs. The first driving component 21 can be a cylinder or an electric push rod, and the clamping component 22 can be made of stainless steel. The tops of the two connecting components 221 are respectively hinged to the two sides of the hopper 1 near the discharge port 11, and the bottoms of the two connecting components 221 are respectively fixedly connected to the two abutment components 222. The two abutment components 222 are constructed to fit the shape of the discharge port 11, such as an arc. The first driving component 21 is horizontally arranged and includes a driving part 211 and a telescopic part 212. The end of the driving part 211 away from the telescopic part 212 is connected to the side wall of the first connecting component 221 near the hopper 1, and the end of the telescopic part 212 away from the driving part 211 is connected to the side wall of the second connecting component 221 near the hopper 1. The first driving member 21 synchronously drives the two abutting members 222 via two connecting members 221 to move closer or further away from each other on both sides of the discharge port 11, so that the abutting members 222 can abut or separate from the discharge port 11. By utilizing the shape matching between the abutting members 222 and the discharge port 11, the stability of the packaging bag during the filling process is improved.

[0033] In one embodiment, the connector 221 includes two first connecting handles 2211, two second connecting handles 2212, and a connecting rod 2213. The bottom ends of the two first connecting handles 2211 are respectively connected to the same side of the abutment 222 away from the hopper 1. The bottom ends of the two second connecting handles 2212 are respectively connected to the two ends of the connecting rod 2213. The top ends of the two first connecting handles 2211 are respectively connected to the side wall of the connecting rod 2213. The top ends of the two first connecting handles 2211 are hinged to the hopper 1.

[0034] In this embodiment, refer to Figure 1 and Figure 2 The bottom ends of the two first connecting handles 2211 are fixedly connected to the same side of the abutment 222 away from the hopper 1, and the bottom ends of the two second connecting handles 2212 are fixedly connected to both ends of the connecting rod 2213, respectively. The top ends of the two first connecting handles 2211 are fixedly connected to the side wall of the connecting rod 2213, and the top ends of the two first connecting handles 2211 are hinged to the hopper 1. The design of the connecting member 221 facilitates the smooth transmission of the first connecting handles 2211 and the second connecting handles 2212, ensuring that the two abutments 222 maintain high synchronization and accuracy during movement. At the same time, the design of the connecting member 221 ensures that the abutment 222 fixes the bag opening at a constant angle and trajectory, enhancing the movement stability and operational reliability of the clamping assembly 2.

[0035] In one embodiment, the second connecting handle 2212 is provided to protrude away from the hopper 1 to avoid the hopper 1.

[0036] In this embodiment, the protrusion of the second connecting handle 2212 increases the distance between the second connecting handle 2212 and the hopper 1, preventing mechanical interference or collision between the second connecting handle 2212 and the hopper 1 during swinging or operation. The protrusion reduces potential mechanical wear and jamming risks, ensuring the smoothness and reliability of the overall movement of the connector 221 and extending the service life of the component.

[0037] In one embodiment, the first connecting handle 2211 is provided to protrude in the direction of the hopper 1, for proximity to the discharge port 11.

[0038] In this embodiment, the protrusion of the first connecting handle 2211 forms a configuration close to the hopper 1 on one side. On the one hand, the protrusion reduces the space occupied by the clamping component 2, which is beneficial for the integration and miniaturization of the equipment; on the other hand, the protrusion optimizes the force transmission path of the abutment 222 when fixing the bag opening, improving the fastening efficiency and reliability of the abutment 222 on the bag.

[0039] In one embodiment, the abutment member 222 includes a connecting clearance section 2221 and a clamping section 2222. The clearance section 2221 has a shape that matches the outer peripheral shape of the discharge port 11, and the clamping section 2222 is connected to the clearance section 2221 and located on the side of the discharge port 11.

[0040] In this embodiment, refer to Figure 2 and Figure 3 The two clamping sections 2222 are respectively connected to the two ends of the avoidance section 2221 near the two clamping sections 2222. The avoidance section 2221 is designed to match the outer peripheral shape of the discharge port 11, so that when the abutment 222 approaches the discharge port 11, the avoidance section 2221 can guide and close the bag opening, which is beneficial for the bag to align with the discharge port 11 when it approaches the discharge port 11.

[0041] In one embodiment, the abutment member 222 includes a clearance section 2221 and two clamping sections 2222, the two clamping sections 2222 being respectively connected to both sides of the clearance section 2221.

[0042] In this embodiment, the clamping section 2222 can be a hollow square tube. The side wall of the clamping section 2222 away from the discharge port 11 is connected to the side wall of the first connecting handle 2211 near the hopper 1. After the two clearance sections 2221 move synchronously towards the discharge port 11 to fix the packaging bag to the discharge port 11, a gap is left between the two clamping sections 2222 located on two different abutment members 222 and on the same side of the two abutment members 222. This gap can prevent the operator from being pinched during the process of assisting in fixing the packaging bag.

[0043] In one embodiment, the clamping member 22 further includes a seal 223, which is disposed on the side of the abutment member 222 facing the discharge port 11. The seal 223 includes a belt 2231 and a bumper block 2232. The belt 2231 is disposed on the surface of the avoidance section 2221, and the bumper block 2232 is disposed on the surface of the clamping section 2222.

[0044] In this embodiment, the belt 2231 has a certain degree of elasticity and flexibility, which can effectively fill the tiny gaps when the avoidance section 2221 is tightly fitted with the discharge port 11 and the opening of the packaging bag, thereby improving the airtightness of the entire fixed area. At the same time, the belt 2231 also acts as a buffer, preventing the hard avoidance section 2221 from directly contacting the packaging bag and causing wear or damage to the packaging bag. The anti-collision block 2232 can be made of materials such as rubber or sponge. The anti-collision block 2232 can prevent the clamping section 2222 from scratching the operator when it comes into direct contact with the operator.

[0045] In one embodiment, the tapping assembly 3 includes a tapping member 31 and a third driving member 32. The tapping member 31 is spaced apart at the bottom of the discharge port 11, and the third driving member 32 is drivenly connected to the tapping member 31 to push the tapping member 31 to extend toward the side where the discharge port 11 is located.

[0046] In this embodiment, refer to Figure 1 The striking component 31 can be made of metal or plastic. It is horizontally positioned, with the end of the striking component 31 furthest from the third driving component 32 and connected to it via a drive mechanism. The third driving component 32 can be a cylinder or an electric telescopic rod. The striking component 31 solves the problem in existing granular material packaging processes where some less fluid materials cannot fully fall into the bag. By striking the packaging bag with the striking component 31, the material is effectively loosened, promoting smooth flow into the bag and preventing blockage. The striking component 31 ensures that the granular material fills the packaging bag, improving its utilization efficiency and accelerating the packaging process.

[0047] In one embodiment, the end of the striking member 31 away from the third driving member 32 is planar.

[0048] In this embodiment, the end of the striking member 31 furthest from the third driving member 32 can be circular or square, and the end of the striking member 31 furthest from the third driving member 32 is vertically arranged. The planar shape facilitates a larger contact area between the striking member 31 and the surface of the packaging bag, enabling the even transmission and dispersion of the striking force. The planar shape also helps to break up bridging phenomena inside the packaging bag, avoiding excessive local stress that could damage the packaging bag, thus protecting it and enhancing the operational safety of the striking member 31.

[0049] In one embodiment, the packaging bag rapid filling device further includes a lifting component 4, which includes a fourth driving member 41, a hook 42, a fifth driving member 43, and a baffle 44. The fourth driving member 41 is spaced apart on the side of the hopper 1 and is vertically arranged. The hook 42 is detachably connected to the bottom of the fourth driving member 41 and is used to lift and lower the hook 42 along the direction of gravity. The baffle 44 is detachably connected to the opening of the hook 42. The fifth driving member 43 is used to drive the baffle 44 to abut or separate from the opening of the hook 42.

[0050] In this embodiment, the clamping component 2 is suitable for fixing packaging bags with small or moderate diameters, while the lifting component 4 can fix large-diameter packaging bags. The packaging bag rapid filling device includes four lifting components 4, which are spaced apart around the hopper 1. The fourth driving component 41 can be a cylinder or an electric telescopic rod. The fourth driving component 41 is vertically arranged, and its bottom is detachably connected to the top of the hook 42. The fifth driving component 43 is vertically arranged and located on the side of the fourth driving component 41 closest to the hopper 1. The top of the fifth driving component 43 is detachably connected to the fourth driving component 41, and its bottom is detachably connected to the top of the baffle 44. The baffle 44 is hinged to the opening of the hook 42. The fifth driving component 43 is used to drive the baffle 44 to abut or separate from the opening of the hook 42, thus completing the gripping and release of the packaging bag opening by the hook 42. The lifting components 4 expand the applicability of the packaging bag rapid filling device and improve the efficiency of fixing packaging bags.

[0051] The implementation principle of the rapid filling device for packaging bags according to this application embodiment is as follows: This rapid filling device for packaging bags achieves stable and rapid fixation of the packaging bag and the discharge port 11 through the clamping component 2, avoiding the problem of material leakage caused by the packaging bag not being able to be fixed. The tapping component 3 evenly distributes the material falling into the packaging bag, and the lifting component 4 is used to fix large-sized packaging bags that cannot be fixed by the clamping component 2. Compared with the prior art, this rapid filling device for packaging bags has the advantages of stably fixing the packaging bag at the discharge port 11 and high filling efficiency.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
