Description

Technical Field

[0001] This utility model relates to the field of packaging scales, specifically a double-auger hopperless ton bag scale. Background Technology

[0002] A ton bag scale is a large-scale weighing and packaging equipment. The product is positioned as an industrial packaging machine that integrates electronic weighing, automatic bag removal and dust removal functions. It is mainly used in the mining, chemical, building materials, grain and feed industries.

[0003] The equipment consists of a pneumatic hook clamping system, an air inflation and deflation mechanism, a feeding and metering control mechanism, and a hydraulic lifting system. It uses an electronic platform scale for metering and supports automatic tare, zeroing, and drop correction functions.

[0004] Currently, when filling ton bags with materials, the filling process needs to be stopped when the weight of the ton bag reaches the predetermined requirement. However, during this stopping process, there may still be residual material in the filling channel that continues to be injected into the ton bag, causing the weight of the ton bag to exceed the expected range and affecting the accuracy of the materials stored in the ton bag.

[0005] Therefore, how to design a ton bag scale that avoids or reduces the amount of remaining material in the injection channel from continuing to enter the ton bag after the ton bag scale stops injecting material is a problem that needs to be solved. Utility Model Content

[0006] Purpose of the utility model: To provide a double-auger hopperless ton bag scale to solve the above-mentioned problems existing in the prior art.

[0007] Technical solution: A double-auger hopperless ton bag scale, comprising:

[0008] The base frame, and the unloading weighing position installed on the base frame;

[0009] The unloading and weighing station includes an unloading section, a weighing section, and a blower section installed on the base frame;

[0010] The unloading section includes:

[0011] A discharge input bin is installed on the base frame, and a stirring paddle is provided inside the discharge input bin; a stirring motor is provided at the input end of the stirring paddle;

[0012] The auger conveyor is designed with two sets of different conveying flow rates. Each set includes a conveying channel connected to the unloading input bin, an auger adapted in the conveying channel, and an auger motor installed on the base frame with its output end connected to the auger drive.

[0013] The stirring paddle is located above the auger conveyor;

[0014] The auger conveyor has two different input flow rates, one large and one small. The diameter of the conveying channel can be designed to be one large and one small, thereby changing the input flow rate.

[0015] The unloading output bin is connected to the conveying channel, and the bottom of the unloading output bin is connected to the unloading cylinder;

[0016] The interceptor includes an interceptor cylinder hinged to the unloading input bin, an interceptor swing frame hinged to the output end of the interceptor cylinder, an interceptor rotating shaft connected to the interceptor swing frame and extending into the unloading input bin, and an interceptor bucket connected to the interceptor rotating shaft and adapted to the unloading input bin.

[0017] This invention utilizes two sets of auger conveyors with different flow rates to transport materials to the unloading output bin, from where they are discharged into ton bags via the unloading cylinder. In the initial stage of material transport, the two auger conveyors with different flow rates can operate simultaneously pneumatically, quickly feeding materials into the ton bags. As the material in the ton bags gradually increases, the auger conveyor with the larger flow rate is paused, while the auger conveyor with the smaller flow rate continues to operate. When it is necessary to pause material input, the auger conveyor with the smaller flow rate is stopped, and an interceptor is used to intercept material in the unloading output bin. By cooperating with the interceptor, the auger conveyor with the smaller flow rate reduces the amount of material continuing to enter the ton bags, thus preventing overloading.

[0018] In a further embodiment, a material feeding cylinder is provided at the top of the unloading output bin, and a material feeding shaft extending into the unloading output bin is provided at the output end of the material feeding cylinder.

[0019] In a further embodiment, the unloading cylinder is provided with a baffle plate to divide the unloading cylinder into a material passage and an air passage.

[0020] In a further embodiment, the blower section includes:

[0021] A blower is mounted on the base frame;

[0022] The blower pipe has one end connected to the output port of the blower and the other end connected to the ventilation duct.

[0023] In a further embodiment, the weighing unit includes:

[0024] The bag-type weighing device includes a fixed frame mounted on the base frame and a lifting cylinder connected to the fixed frame.

[0025] A lifting guide rod inserted into the fixed frame, a lifting frame body connected to the lifting guide rod and connected to the output end of the lifting cylinder, multiple weighing arms connected to the lifting frame body, and a weighing buckle connected to the weighing arms;

[0026] The bag opening fixing component includes a corrugated telescopic cylinder sleeved on and connected to the unloading cylinder, a fixed cylinder connected to the corrugated telescopic cylinder, a bag opening fixing frame hinged to the fixed cylinder, and a bag opening fixing cylinder hinged to the lifting frame and with its output end hinged to the bag opening fixing frame.

[0027] The fixed cylinder is connected to the lifting frame.

[0028] In a further embodiment, the weighing buckle includes:

[0029] The fastener is fitted onto the weighing arm;

[0030] The fastener assembly includes a fixed fastener tooth fixedly connected to the fastener frame and a movable fastener tooth hinged to the fastener frame;

[0031] A tooth-clamping cylinder is connected to the buckle frame, and the output end of the tooth-clamping cylinder is hinged to the end of the movable tooth.

[0032] In a further embodiment, the weighing arm is equipped with a weight sensor, and the buckle abuts against the weight sensor.

[0033] In a further embodiment, a weight sensor is provided on the movable buckle tooth.

[0034] In a further embodiment, a weight sensor is provided on the base frame, and the fixed frame is connected to the weight sensor.

[0035] Beneficial Effects: This utility model discloses a double-auger bucketless ton bag scale. This utility model uses two sets of auger conveyors with different conveying flow rates to transport materials to the unloading output bin, and then unload them into ton bags through the unloading cylinder. The two auger conveyors with different flow rates can operate pneumatically simultaneously in the initial stage of material transport, quickly completing the material input into the ton bag. As the material in the ton bag gradually increases, the auger conveyor with the larger flow rate is paused, while the auger conveyor with the smaller flow rate continues to operate. When it is necessary to pause material input, the auger conveyor with the smaller flow rate is stopped, and an interceptor is used to intercept the material in the unloading output bin. By using the smaller flow rate auger conveyor in conjunction with the interceptor, the amount of material continuing to enter the ton bag from the unloading output bin is reduced, thus preventing the ton bag from becoming overloaded.

[0056] This application relates to a double-auger hopperless ton bag scale, which will be explained in detail below through specific embodiments.

[0057] A double-auger hopperless ton bag scale includes:

[0058] Base frame 1, and unloading weighing position 2 installed on the base frame 1;

[0059] The unloading and weighing station 2 includes an unloading part 21, a weighing part 22, and a blower part 23 installed on the base frame 1;

[0060] The unloading section 21 includes:

[0061] The unloading input bin 211 is installed on the base frame 1. The unloading input bin 211 is equipped with a stirring paddle 218. The input end of the stirring paddle 218 is equipped with a stirring motor. The stirring paddle 218 is driven by the stirring motor, which avoids the accumulation of materials in the unloading input bin 211.

[0062] The auger conveyor 212 is designed with two sets and different conveying flow rates. Each set includes a conveying channel connected to the unloading input bin 211, an auger adapted in the conveying channel, and an auger motor 213 installed on the base frame 1 and whose output end is connected to the auger drive.

[0063] The stirring paddle 218 is located above the auger conveyor 212;

[0064] The auger conveyor 212 has two different input flow rates, one large and one small. The diameter of the conveying channel can be designed to be one large and one small, thereby changing the input flow rate.

[0065] The unloading output bin 216 is connected to the conveying channel, and the bottom of the unloading output bin 216 is connected to the unloading cylinder 217;

[0066] The interceptor 214 includes an interceptor cylinder 214A hinged to the unloading input chamber 211, an interceptor swing frame 214B hinged to the output end of the interceptor cylinder 214A, an interceptor rotating shaft 214C connected to the interceptor swing frame 214B and extending into the unloading input chamber 211, and an interceptor bucket 214D connected to the interceptor rotating shaft 214C and adapted to the unloading input chamber 211.

[0067] This invention utilizes two sets of auger conveyors 212 with different flow rates to transport materials to the unloading output bin 216, from where they are discharged into ton bags via the unloading cylinder 217. The two auger conveyors 212 with different flow rates can operate simultaneously pneumatically in the initial stage of material transport, quickly feeding materials into the ton bags. As the material in the ton bags gradually increases, the auger conveyor 212 with the larger flow rate is paused, while the auger conveyor 212 with the smaller flow rate continues to operate. When it is necessary to pause material input, the auger conveyor 212 with the smaller flow rate is stopped, and the material in the unloading output bin 216 is intercepted by the interceptor 214. By cooperating with the interceptor 214, the auger conveyor 212 with the smaller flow rate reduces the amount of material continuing to enter the ton bags from the unloading output bin 216, thus preventing the ton bags from becoming overloaded.

[0068] The top of the unloading output bin 216 is provided with a material passage cylinder 215. The output end of the material passage cylinder 215 is provided with a material passage shaft extending into the unloading output bin 216. By designing the material passage cylinder 215 and the material passage shaft, when the material in the unloading output bin 216 comes into contact with each other, the material passage cylinder 215 drives the material passage shaft to rise and fall, impacting and breaking up the accumulation of material, thus avoiding the accumulation of material in the unloading output bin 216.

[0069] The unloading cylinder 217 is provided with a partition 217A, which divides the unloading cylinder 217 into a material passage and an air passage.

[0070] The blower section 23 includes:

[0071] Blower 231 is mounted on the base frame 1;

[0072] The blower pipe 232 is connected at one end to the output port of the blower 231 and at the other end to the ventilation duct.

[0073] The weighing unit 22 includes:

[0074] The bag-ear weighing component 221 includes a fixed frame 221A mounted on the base frame 1, and a lifting cylinder 221B connected to the fixed frame 221A.

[0075] The lifting guide rod 221C is inserted into the fixed frame 221A, the lifting frame 221D is connected to the lifting guide rod 221C and connected to the output end of the lifting cylinder 221B, the multiple weighing arms 221F are connected to the lifting frame 221D, and the weighing buckle 221E is connected to the weighing arm 221F.

[0076] The bag opening fixing component 222 includes a corrugated telescopic cylinder 222B sleeved on and connected to the unloading cylinder 217, a fixed cylinder 222A connected to the corrugated telescopic cylinder 222B, a bag opening fixing frame 222D hinged to the fixed cylinder 222A, and a bag opening fixing cylinder 222C hinged to the lifting frame 221D and whose output end is hinged to the bag opening fixing frame 222D; the fixed cylinder 222A is connected to the lifting frame 221D.

[0077] The weighing buckle 221E includes:

[0078] The buckle 221E1 is fitted onto the weighing arm 221F;

[0079] The fastener assembly includes a fixed fastening tooth 221E3 fixedly connected to the fastener frame 221E1, and a movable fastening tooth 221E4 hinged to the fastener frame 221E1;

[0080] The tooth-clamping cylinder 221E2 is connected to the buckle frame 221E1, and the output end of the tooth-clamping cylinder 221E2 is hinged to the end of the movable tooth 221E4.

[0081] The weighing arm 221F is equipped with a weight sensor, and the buckle 221E1 abuts against the weight sensor.

[0082] A weight sensor is provided on the movable buckle 221E4;

[0083] The position of the weight sensor can also be selected according to actual needs, with only two position options provided.

[0084] Working principle description: During operation, the lifting cylinder 221B drives the lifting frame 221D to descend to the predetermined height. During the lifting process, the fixed cylinder 222A will descend, and the corrugated telescopic cylinder 222B will adapt. After descending to the predetermined position, the buckle cylinder 221E2 drives the movable buckle 221E4 to move, so that the peripheral lifting lugs of the ton bag are hooked on the movable buckle body. The buckle cylinder 221E2 drives the movable buckle 221E4 to engage with the fixed buckle 221E3, thus completing the hooking and unhooking of the ton bag lifting lugs.

[0085] Next, the inlet of the ton bag is placed on the fixing cylinder 222A. The bag opening fixing cylinder 222C drives the bag opening fixing bracket 222D to press the inlet of the ton bag onto the fixing cylinder 222A, thus completing the fixing.

[0086] After being fixed, the lifting cylinder 221B drives the lifting frame 221D to rise, and by lifting the lifting lugs of the ton bag, the ton bag is suspended in the air, and then the material is injected.

[0087] During injection, the two sets of auger conveyors 212 move simultaneously, transporting the material in the unloading input bin 211 to the unloading output bin 216, and unloading it into the ton bag through the unloading cylinder 217. As the material in the ton bag continues to be injected, when the weight is about to reach the target, the high-flow-rate faster conveyor stops, and the low-flow-rate auger conveyor 212 continues to work. When the weight of the ton bag reaches the target, the low-flow-rate auger conveyor 212 stops, and the intercepting cylinder 214A drives the intercepting swing frame 214B to move, which drives the intercepting shaft 214C to rotate, causing the interceptors to block the unloading output bin 216, thus completing the injection work.

[0088] Before and during material injection, air is introduced into the ventilation duct by blower 231 and enters the ton bag, causing the ton bag to inflate and preventing the ton bag from not being able to open completely, which would affect the entry of material.

[0089] The weight of the ton bag is sensed by a weight sensor.

[0090] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
