Description

Technical Field

[0001] This application relates to the technical field of feeding hoppers, and in particular to a vibrating slow-feed feeding hopper. Background Technology

[0002] The multi-head combination weighing system is a high-precision weighing device mainly used to automatically complete packaging processes such as metering, feeding, filling, bag making, and date printing. The system consists of multiple independent weighing units, which are processed and analyzed by a computer control system to obtain accurate weight data. Its main components include a multi-head weigher, a hoist, a work platform, and a vertical packaging machine.

[0003] Currently, multi-head combined weigher material dispensing and packaging systems often have a feeding hopper at the loading end to uniformly supply the required materials to the system. Patent CN105984734A discloses a vibrating feeding hopper. The feeding hopper is connected to a frame via a support frame and is positioned above a conveyor belt. The feeding hopper includes a main body, a first feeding plate, and a second feeding plate. The main body is box-shaped, with an inlet at the top and an outlet at the bottom. The first feeding plate is hinged to the inner wall of the main body, with a hinge shaft at one end. A hinge hole is located on the inner wall of the main body, with the hinge shaft positioned within the hinge hole. A vibrator is mounted on the first feeding plate, which is located directly below the inlet. The second feeding plate is inclined at the outlet of the main body, with opposite inclination directions. This invention improves the uniformity and reliability of material distribution.

[0004] However, although the material is evenly distributed in the feeding hopper, the diameter of the discharge port is fixed, making it difficult to adjust the material discharge amount according to actual production needs, resulting in a narrow range of applications for the feeding hopper. Utility Model Content

[0005] To facilitate adjustment of the discharge rate according to actual needs and improve the applicability of the feeding hopper, this application provides a vibrating slow-feeding feeding hopper.

[0006] This application provides a vibratory slow-feeding hopper, which adopts the following technical solution:

[0007] A vibrating slow-feeding hopper includes a fixed frame disposed on one side of the feeding end of a multi-head combined scale dispensing and boxing system. The fixed frame contains a feeding hopper, and the bottom end of the feeding hopper has a discharge port. The fixed frame contains a vibrating element, and the top surface of the vibrating element has a guide rail disposed below the discharge port. The side wall of the feeding hopper has an adjustment port that communicates with the discharge port. The feeding hopper is provided with an adjustment mechanism for adjusting the size of the adjustment port.

[0008] By adopting the above technical solution, when materials need to be supplied to the feeding end of the multi-head combined scale dispensing and packaging system, the materials are first placed upside down in the feeding hopper. Under the action of gravity, the materials are sent out from the discharge port and accumulated on the guide rail. Then, the vibrating component is activated, and the vibrating component transmits the vibration force to the guide rail. The guide rail then transmits the vibration of the materials to the feeding end of the multi-head combined scale dispensing and packaging system. When it is necessary to adjust the discharge amount of materials, the diameter of the adjusting port is adjusted by the adjusting mechanism, thereby adjusting the amount of materials accumulated on the guide rail. This is beneficial for adjusting the discharge amount according to actual needs and improving the applicability of the feeding hopper.

[0009] Optionally, the adjusting mechanism includes an adjusting door, which is slidably disposed on one side of the feeding hopper, and the adjusting door covers the adjusting opening. The feeding hopper is also provided with a fixing component for fixing the adjusting door.

[0010] By adopting the above technical solution, when it is necessary to adjust the size of the adjustment port, the adjustment gate is first slid along the side wall of the feeding hopper, and then the adjustment gate is fixed in the current position by the fixing component. The size of the adjustment port is adjusted by sliding the adjustment gate, which helps to improve the stability of the discharge volume adjustment.

[0011] Optionally, the fixing component includes a first bolt, and a through hole is provided on the surface of the adjusting door. The first bolt is slidably connected to the through hole and threadedly connected to the feeding hopper.

[0012] By adopting the above technical solution, when the sliding adjustment gate needs to be moved, the first bolt is loosened and then the adjustment gate is moved to slide. At this time, the first bolt slides in the slot at the same time. When the adjustment gate needs to be fixed, the first bolt is tightened. At this time, the adjustment gate is pressed against and fixed to the side wall of the feeding hopper, which helps to improve the convenience of fixing or moving the adjustment gate.

[0013] Optionally, the outer wall of the regulating door is provided with a handle.

[0014] By adopting the above technical solution, the sliding adjustment door can be moved by a handle, which improves the convenience of sliding adjustment of the door.

[0015] Optionally, the top surface of the feeding hopper is provided with an abutting edge, the abutting edge overlaps the top surface of the fixing frame, and a second bolt is provided through the abutting edge, the second bolt being threadedly connected to the fixing frame.

[0016] By adopting the above technical solution, when it is necessary to install the feeding hopper, first insert the feeding hopper into the fixed frame from top to bottom until the abutting edge abuts the top surface of the fixed frame, and then tighten the second bolt by thread. At this time, the feeding hopper is fixed in the fixed frame, which helps to improve the stability of the feeding hopper assembly and disassembly.

[0017] Optionally, a pressure plate is pressed together on the top surface of adjacent abutting edges, and a third bolt is provided through the pressure plate, passing through the abutting edge, and the third bolt is threadedly connected to the fixing frame.

[0018] By adopting the above technical solution, when the abutting edge abuts against the top surface of the fixed frame, the pressure plate is pressed against the top surface of the adjacent abutting edge, and then the third bolt is passed through the pressure plate and the abutting edge in sequence, and then threadedly connected to the fixed frame. At this time, the pressure plate is pressed tightly against the top surface of the adjacent abutting edge, which helps to prevent the abutting edge from warping and further improves the stability of the feeding hopper fixed in the fixed frame.

[0019] Optionally, the guide rail is inclined downward toward the feeding end of the multi-head combined scale dispensing and packaging system.

[0020] By adopting the above technical solution, the inclined guide rail helps to improve the stability of material conveying along the guide rail towards the feeding end of the multi-head combined scale dispensing and boxing system.

[0021] Optionally, pads are provided at the bottom corners of the fixing frame.

[0022] By adopting the above technical solution, the vibration force of the vibrating component can be reduced and the noise in the processing workshop can be reduced under the action of the pad.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] When materials need to be supplied to the feeding end of the multi-head combination scale dispensing and packaging system, the materials are first inverted into the feeding hopper. Under the action of gravity, the materials are sent out from the discharge port and accumulate on the guide rail. Then, the vibrator is activated, and the vibrator transmits the vibration force to the guide rail. The guide rail then transmits the vibration of the materials to the feeding end of the multi-head combination scale dispensing and packaging system. When it is necessary to adjust the discharge amount of materials, the diameter of the adjustment port is adjusted by the adjustment mechanism, thereby adjusting the amount of materials accumulated on the guide rail. This is beneficial for adjusting the discharge amount according to actual needs and improving the applicability of the feeding hopper. Attached Figure Description

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] See Figures 1-3 A vibrating slow-feeding hopper includes a fixed frame 1, which is placed on the feeding end side of a multi-head combined weighing and packaging system 2. The multi-head combined weighing and packaging system 2 is a high-precision weighing device mainly used to automatically complete packaging processes such as metering, feeding, filling, bag making, and date printing. A vibrating element 3, a linear vibrator, is fixedly installed inside the fixed frame 1, and a guide rail 4 is fixedly connected to the top surface of the vibrating element 3. A feeding hopper 5 is also installed inside the fixed frame 1. The top surface of the feeding hopper 5 is open, and the bottom surface of the feeding hopper 5 has a discharge port 6, which is located above the guide rail 4. An adjustment port 7 is also provided on the side wall of the feeding hopper 5, which is connected to the discharge port 6. The feeding hopper 5 is also equipped with an adjustment mechanism for changing the diameter of the adjustment port 7.

[0031] When materials need to be supplied to the multi-head combined scale dispensing and packaging system 2, the materials are first inverted into the feeding hopper 5. After being loaded into the feeding hopper 5, the materials are collected on the guide rail 4 through the discharge port 6. Then, the vibrator 3 is activated, transmitting vibration force to the guide rail 4. Under the action of the guide rail 4, the materials are collected along the guide rail 4 at the feeding end of the multi-head combined scale dispensing and packaging system 2. When it is necessary to increase or decrease the discharge amount at the discharge port 6, the diameter of the adjusting port 7 is increased or decreased by the adjusting mechanism, thereby adjusting the discharge amount according to actual needs.

[0032] See Figure 2 To reduce the overall vibration force of the mounting frame 1 and the noise generated when the vibrating component 3 starts, rubber feet 8 are fixedly installed at the bottom corners of the mounting frame 1. The mounting feet 8 are used to lift the mounting frame 1, and the rubber reduces the noise generated between the mounting frame 1 and the ground when it vibrates.

[0033] For details, see Figure 2The adjustment mechanism includes an adjustment door 9, which is slidably installed on one side of the feeding hopper 5 and covers the adjustment port 7.

[0034] In addition, to facilitate the fixing of the regulating gate 9, the feeding hopper 5 is also equipped with a fixing assembly, which includes a first bolt 10. Two slots 11 are provided through the surface of the regulating gate 9, symmetrically arranged on the outer side of the regulating gate 9. The number of first bolts 10 is the same as the number of slots 11, and the fixing end of the first bolt 10 is slidably connected to the slot 11. The fixing end of the first bolt 10 passes through the slot 11 and is threadedly connected to the feeding hopper 5.

[0035] When it is necessary to adjust the material discharge rate of the feeding hopper 5, first loosen the first bolt 10, and then slide the adjusting gate 9 along the vertical direction of the feeding hopper 5. At this time, the adjusting gate 9 slides up and down under the guidance of the first bolt 10. When the adjusting gate 9 moves upward, the diameter of the adjusting port 7 increases, and the material discharge rate increases accordingly; when the adjusting gate 9 moves downward, the diameter of the adjusting port 7 decreases, and the material discharge rate decreases accordingly.

[0036] It is worth mentioning that, see Figure 2 A handle 12 is fixedly connected to the outer wall of the regulating door 9. The handle 12 drives the regulating door 9 to move up and down, improving the convenience of sliding adjustment of the regulating door 9.

[0037] It should be noted that, see Figure 2 To improve the stability of material feeding, the guide rail 4 is inclined downwards towards the feeding end of the multi-head combined scale dispensing and packaging system 2. The inclined guide rail 4 ensures that the material falls stably into the feeding end.

[0038] See Figure 2 To improve the stability of the feeding hopper 5 during installation, an abutment edge 13 is fixedly connected to the top edge of the feeding hopper 5. The abutment edge 13 is bent horizontally and overlaps the top surface of the fixing frame 1. A second bolt 14 passes through the abutment edge 13. There are multiple second bolts 14, and the fixing ends of the multiple second bolts 14 pass through the abutment edge 13 respectively, and the fixing ends of the multiple second bolts 14 are threadedly connected to the fixing frame 1.

[0039] When it is necessary to install the feeding hopper 5, first insert the feeding hopper 5 into the fixing frame 1 until the abutment edge 13 overlaps the top surface of the fixing frame 1. Then, insert the fixing ends of the multiple second bolts 14 through the abutment edge 13 and thread them into the fixing frame 1. At this time, the feeding hopper 5 is fixed in the fixing frame 1.

[0040] See Figure 2To prevent the abutment edge 13 from flipping over and causing the fixing frame 1 to fall off, a pressure plate 15 is pressed together on the top surface of adjacent abutment edges 13. A third bolt 16 passes through the pressure plate 15. There are two third bolts 16, each corresponding to one of the two adjacent abutment edges 13. The fixing end of the third bolt 16 passes through the pressure plate 15 and the abutment edge 13 in sequence, and the fixing end of the third bolt 16 is threadedly connected to the fixing frame 1.

[0041] After the abutment edge 13 is overlapped and fixed to the fixing frame 1 by the second bolt 14, the pressure plate 15 is pressed onto the top surface of the two adjacent abutment edges 13. Then, the fixing end of the third bolt 16 passes through the fixing plate and the abutment edge 13 in sequence. Then, the third bolt 16 is screwed into the top surface of the fixing frame 1. At this time, the pressure plate 15 abuts against the two adjacent abutment edges 13.

[0042] The working principle of a vibrating slow-feeding hopper:

[0043] Adjust the diameter of the regulating port 7 according to the actual required material discharge volume, loosen the first bolt 10, and drive the regulating gate 9 up and down via the handle 12. When the regulating gate 9 moves upward, the diameter of the regulating port 7 increases, and the material discharge volume increases accordingly; when the regulating gate 9 moves downward, the diameter of the regulating port 7 decreases, and the material discharge volume decreases accordingly. After the regulating gate 9 is adjusted, tighten the first bolt 10, at which point the regulating gate 9 is fixed to the outer wall of the feeding hopper 5.

[0044] When materials need to be supplied to the multi-head combined scale dispensing and packaging system 2, the materials are first inverted into the feeding hopper 5. After being loaded into the feeding hopper 5, the materials are collected on the guide rail 4 through the discharge port 6. Then, the vibrator 3 is activated, and the vibrator 3 transmits the vibration force to the guide rail 4. Under the action of the guide rail 4, the materials are collected along the guide rail 4 at the feeding end of the multi-head combined scale dispensing and packaging system 2.

[0045] In summary, by adjusting the diameter of the adjusting port 7 through the adjusting mechanism, the amount of material accumulated on the guide rail 4 can be adjusted, which is beneficial to adjust the discharge volume according to actual needs and improve the applicability of the feeding hopper 5.

[0046] 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.
