Description

Technical Field

[0002] At present, automatic quantitative packaging machines are widely used as key equipment in grain, food, chemical, fertilizer, building materials, pesticide and other industries. However, the quantitative packaging process is divided into feeding, quantitative and packaging processes. Usually, the bulk materials are divided into small loads of predetermined mass by automatic weighing devices in the form of automatic weighing devices, and then the subsequent packaging process is carried out.

[0003] In the prior art, the patent document CN220465860U is referred to. The device proposed in the patent document drives the push plate to reciprocate once each time by a rotating motor, and quantitatively transports the material to the container box. The controller controls the stepper motor to rotate a step angle to transport the new container box to the bottom of the discharge port. The continuous quantitative loading of the material can be completed by repeated operations, which solves the problem that employees need to manually place the new container box at the corresponding place of the conveyor, which requires more operators and has low work efficiency.

[0004] However, in actual use, although the packaging machine proposed in the above patent document can quantitatively transport materials and reduce manpower loss and improve work efficiency, in the process of quantitative transportation of materials, the materials are easily adsorbed on the slope when quantitatively unloading by sliding down the materials, which can easily affect the accuracy of subsequent unloading of materials. For this reason, we provide a quantitative packaging machine to solve the above problems. Utility Model Content

[0023] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0024] As described in the background art, when the material falls by means of inclined sliding, it is easy for the material to adsorb on the slope during quantitative feeding, which is likely to affect the accuracy of subsequent feeding. Therefore, this embodiment provides a quantitative packaging machine, which can not only specify the weight of the feeding material according to requirements, but also vibrate the material during feeding to improve the accuracy of the actual weight of the discharged material, and avoid the situation that the actual feeding weight is affected by incomplete discharging or residue of the material.

[0025] See Figure 1 - Figure 5 , this embodiment provides a quantitative packaging machine. It includes a packaging machine box body 1, and a feeding hopper 2 is fixedly communicated with the feeding groove on the upper surface of the packaging machine box body 1. A quantity control component is arranged in the feeding hopper 2.

[0026] Refer to Figures 1 to 4 , the setting of this quantity control component can facilitate the uniform falling of the dumped material into subsequent components in batches, and can set the discharge amount of the falling material according to requirements, thus facilitating the subsequent weighing work of the material and greatly improving the accuracy and practicability of the material quantification.

[0027] The quantity control component includes a first discharge roller 3 rotatably connected to the inner wall of the feeding hopper 2, and a rotating motor 4 installed on the front of the packaging machine box body 1. The output rotating shaft of the rotating motor 4 penetrates the front of the packaging machine box body 1 and is connected to the first discharge roller 3. The quantity control component is used to control the quantitative conveying of the material.

[0028] By setting the first discharge roller 3, the material can be stored in the grooves on the surface of the first discharge roller 3 after being dumped into the feeding hopper 2, and the first discharge roller 3 with different groove sizes can be installed according to requirements to quantitatively convey the material. By starting the rotating motor 4, the output rotating shaft of the rotating motor 4 drives the first discharge roller 3 to rotate, so that the material is rotated and dropped into the weighing hopper 501 through the first discharge roller 3.

[0029] Inside the packaging machine housing 1, a weighing mechanism 5 is provided. The weighing mechanism 5 includes a weighing hopper 501 directly below the output port of the feeding hopper 2, and a discharge assembly and a vibration assembly fixed on the weighing hopper 501. The discharge assembly is used to control the discharge of the weighed material, and the vibration assembly is used to vibrate and slide down the material adsorbed on the inner wall of the weighing hopper 501.

[0030] Reference Figures 1 to 5 , the setting of the weighing mechanism 5 can weigh the falling material, control the discharge of the weighed material through the discharge assembly, and simultaneously knock and vibrate the outer shell of the weighing hopper 501 through the vibration assembly while the material is discharged, so that all the material slides down to the discharge place, thus avoiding the influence of material residue on the actual weight of the material in the package.

[0031] The weighing mechanism 5 further includes a weighing sensor 502 fixed on the inner side wall of the packaging machine housing 1 and connected to the weighing hopper 501. The weighing sensor 502 is used to support the weighing hopper 501 and detect the weight of the material after peeling off the weight of the weighing hopper 501.

[0032] By setting the weighing hopper 501, it is convenient to receive and store the falling material, and the weight of the weighing hopper 501 and the subsequent connecting components is peeled off by the weighing sensor 502, so that the weight of the material can be accurately detected when the material falls into the weighing hopper 501.

[0033] Furthermore, the discharge assembly further includes a connecting shaft 506 rotatably penetrating through the discharge port of the weighing hopper 501, and a second discharge roller 505 sleeved on the outer surface of the connecting shaft 506 and in contact with the inner wall of the weighing hopper 501 and capable of rotating synchronously with the connecting shaft 506.

[0034] By setting the second discharge roller 505, the outer surface of the second discharge roller 505 is provided with grooves, which can facilitate multiple discharging operations of the weighed material, avoid the situation of material blockage caused by one-time discharging, and can drive the second discharge roller 505 to rotate through the subsequent driving component, so as to discharge the weighed material, and stop the rotation of the second discharge roller 505 through the driving component when weighing the material, so as to block the material.

[0035] Furthermore, the discharge assembly includes a double-output shaft motor 503 fixed on the outer surface of the discharge port of the weighing hopper 501. Both output ends of the double-output shaft motor 503 are fixedly connected with driving gears 504, and two symmetrically arranged driven gears 507 meshing with the driving gears 504 on the same side are fixedly connected to the outer surface of the connecting shaft 506.

[0036] By setting a dual-output shaft motor 503, the two output rotating shafts of the dual-output shaft motor 503 drive the driving gear 504 to rotate, causing the driving gear 504 to mesh with the driven gear 507, so that the second discharge roller 505 and the connecting shaft 506 can be driven to rotate by the driven gear 507, and thus it is possible to discharge the weighed material and block it during the weighing of the material.

[0037] Furthermore, the vibration assembly includes striking plates 508 on two sides of the symmetric weighing hopper 501. The vibration assembly also includes a connecting frame 509 fixed on the outer surface of the weighing hopper 501, and a swing plate 5010 hinged to the connecting frame 509 and fixedly connected to the striking plate 508. The striking plate 508 is used to impact and vibrate the outer frame of the weighing hopper 501. A transmission assembly is also provided in the weighing mechanism 5, and the transmission assembly is used for the connected transmission of the discharging assembly and the vibration assembly.

[0038] By setting the striking plate 508, convex points are provided at the contact end of the striking plate 508, which can strike and vibrate the outer shell of the weighing hopper 501. And through the mutual cooperation of the connecting frame 509 and the swing plate 5010, the striking plate 508 can be swung, and thus the outer shell of the weighing hopper 501 can be struck and vibrated during the swinging process of the striking plate 508, avoiding situations such as incomplete discharging and residue of the weighed material in the weighing hopper 501 during discharging.

[0039] The transmission assembly includes an eccentric wheel 5011 fixed at the outer end of the connecting shaft 506, and a transmission plate 5012 hinged to the eccentric wheel 5011. Two connecting plates 5013 that can be unfolded or folded together are hinged to the outer end of the transmission plate 5012. The transmission assembly also includes a connecting rod 5014 connected to the swing plate 5010 and hinged to the connecting plate 5013.

[0040] By setting the eccentric wheel 5011, the eccentric wheel 5011 can drive the transmission plate 5012 to swing as the connecting shaft 506 rotates, causing the upper end of the transmission plate 5012 to push the two connecting plates 5013 to move or fold towards both sides, so that the two striking plates 508 on both sides can be driven to swing through the connecting rod 5014, and thus the outer shell of the weighing hopper 501 can be struck and the material in the weighing hopper 501 can be vibrated and evenly slide down.

[0041] A conveying assembly is also provided in the packaging machine box body 1 directly below the output port of the symmetric weighing hopper 501. By setting the conveying assembly, the material discharged after weighing can be collected, stored and conveyed to the subsequent bag sealing area for sealing, so that the accuracy and working efficiency of the overall device for quantitative material can be greatly improved.

[0042] The conveying assembly includes a storage box 6 below the output port of the symmetric weighing hopper 501, and a conveyor belt 7 installed inside the packaging machine body 1 and used for conveying the storage box 6. A servo motor 8 for driving the movement of the conveyor belt 7 is installed outside the conveyor belt 7.

[0043] Through the setting of the storage box 6, the falling materials can be collected and stored. And by starting the servo motor 8, the servo motor 8 drives the operation of the conveyor belt 7, so that the conveyor belt 7 drives the storage box 6 to be conveyed to the subsequent bag sealing area, thereby enabling the sealing operation of the accurately quantified materials, greatly improving the accuracy and practicability of material packaging.

[0044] Working principle: When quantitatively packaging materials, first pour the materials into the feeding hopper 2. At this time, by starting the rotary motor 4, the output rotating shaft of the rotary motor 4 drives the first discharge roller 3 to rotate in the feeding hopper 2, so that the grooves on the surface of the feeding hopper 2 cause the materials to fall in batches by rotation, and the materials fall into the weighing hopper 501. The falling materials can weigh the materials, and after the weighing is completed, the rotary motor 4 is turned off to stop the feeding.

[0045] At this time, start the double-output shaft motor 503. The two output rotating shafts of the double-output shaft motor 503 drive the driving gear 504 to rotate, so that the driving gear 504 meshes with the driven gear 507, thereby driving the connecting shaft 506 and the second discharge roller 505 to rotate. Furthermore, the materials can fall through the second discharge roller 505. And while the second discharge roller 505 rotates and discharges the materials, the connecting shaft 506 can drive the eccentric wheel 5011 to rotate, so that the eccentric wheel 5011 drives the transmission plate 5012 to rotate, and then pushes the two connecting plates 5013 to expand or contract to both sides. Thus, the knocking plate 508 can be driven by the connecting rod 5014 to knock and vibrate the outer shell of the weighing hopper 501, so that the materials in the weighing hopper 501 fall evenly into the second discharge roller 505, and all the materials are discharged, thereby enabling the accuracy of all material discharging, avoiding the change of the weight of the materials after falling into the storage box 6. Then, by starting the servo motor 8, the servo motor 8 drives the storage box 6 to be conveyed to the bag sealing area through the conveyor belt 7.
