Detailed Description
The multi-channel full-automatic feeding system for the chemical production line is described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 7, the invention relates to a multi-channel full-automatic feeding system for a chemical production line, which comprises a material bag conveying mechanism 3, a material bag carrying mechanism 2 and a material suction mechanism 1.
The material bag conveying mechanism 3 is used for conveying material bags 4 waiting for feeding materials one by one to the upper part of a bearing station on the set material bag bearing mechanism 2, and the material bags 4 can fall down automatically under the action of gravity. The material bag bearing mechanism 2 is used for bearing falling material bags 4, a plurality of bearing stations are arranged on the material bag bearing mechanism 2 in order to realize multi-channel automatic feeding, the falling material bags 4 are automatically fed on each bearing station through the material pumping mechanism 1, and in the process, the material bags 4 do not need to be manually broken in advance, so that the feeding efficiency can be greatly increased.
The material bag conveying mechanism 3 comprises a slide rail 302 and a belt conveyor 301 arranged on the slide rail 302, and the material bags 4 are flatly placed on a belt of the belt conveyor 301 at intervals. Slide rail 302 is the track of two parallels, slide rail 302 can drive band conveyer 301 removal under the effect of external force, thereby realize the synchronous displacement of placing material bag 4 on band conveyer 301 and band conveyer 301, thereby remove the discharge end of band conveyer 301 to the position that material bag 4 need fall down, band conveyer 301 utilizes its self rotation to drive material bag 4 and moves on the belt, make the material bag 4 of foremost fall down on the vacant bearing station of material bag bearing mechanism 2. The material bags 4 are delivered one by one through the mutual matching of the sliding rail 302 and the belt conveyor 301. In the setting process of the slide rail 302, the front end of the slide rail 302 needs to be able to cover the material bag carrying mechanism 2 in the vertical direction, so that the belt conveyor 301 can move to the front end of the material bag carrying mechanism 2, the material bag 4 can fall into the carrying station below the material bag carrying mechanism, and the situation that a certain carrying station cannot receive the falling material bag 4 is avoided.
The slide rail 302 is provided with a power mechanism for driving the belt conveyor 301 to move, such as a motor-driven lead screw, a traction chain, a traction rope, etc., and the arrangement mode is the same as that of the prior art, and is not described herein again.
The material bag carrying mechanism 2 comprises a material bag carrying frame 201 and a plurality of material containing barrels 206 arranged on the material bag carrying frame 201, the material containing barrels 206 are respectively arranged on corresponding carrying stations, and the material containing barrels 206 are arranged at intervals along the conveying direction of the belt conveyor 301 so as to receive the material bags 4 conveyed by the material bag carrying mechanism 2. The material containing barrel 206 is in a barrel shape with an open top, the bottom of the material containing barrel 206 is fixed on the support base 202, the bottom of the material containing barrel 206 is fixedly connected with the support base 202, and the support base 202 is fixed on the material bag bearing frame 201. The supporting base 202 may be provided as one, and all the cartridges 206 are provided on the supporting base 202, or the supporting base 202 and the cartridges 206 may be correspondingly provided one to one, and in this embodiment, a one to one arrangement manner of the supporting base 202 and the cartridges 206 is adopted. Each material containing barrel 206 is provided with a material suction mechanism 1, and the material suction mechanism 1 is used for puncturing the material bag 4 by the falling impact force of the material bag 4 and sucking the material in the material bag 4.
Although there is a device for feeding materials by using a suction method in the prior art, for example, two patents of japanese patent laid-open publication nos. 2012-86905 and CN111762575A both disclose a powder suction device, which can draw materials in a bag body by using a suction method without dumping, but the powder suction devices disclosed in the two patents still need to cut an upper bag opening of a packaging bag to make the upper bag opening in an open state, and then extend a suction pipe into the bag body to suck the materials. Therefore, the powder particle suction device in the prior art does not have the function of bag opening, and needs to be used together with the bag opening device, so that the materials in the bag can be completely sucked, the suction pipe needs to be moved continuously in the suction process, and the posture of the bag body needs to be adjusted so that the last residual materials are collected to the bottom of the bag body. The feeding system can automatically remove the material bag by utilizing the matching action of the gravity of the material bag when the material bag falls and the material suction mechanism, an additional bag removing device is not required to be arranged, the material in the material bag falls to the vicinity of the material suction mechanism under the action of the gravity of the material bag during the process of sucking and feeding, and the posture of the material bag is not required to be adjusted during the process of sucking, so that the feeding system is more convenient and efficient during the use process.
Because the dead angle in the material bag 4 is smaller when the material bag 4 falls on the material suction mechanism 1 in an upright posture, the material in the material bag 4 is more easily sucked, therefore, the diameter of the material containing barrel 206 should be slightly larger than the maximum width of the material bag 4, so that the upper part of the material bag 4 can not be inclined during the flowing process of the material from bottom to top during the material suction.
In order to allow the material bag 4 to vertically fall into the material containing cylinder 206, a guide mechanism for adjusting the falling posture of the material bag 4 is provided above the material containing cylinder 206 so that the material bag 4 can vertically enter the material containing cylinder 206. The guide mechanism is a guide cylinder 207 with two open ends, wherein an outlet at the bottom of the guide cylinder 207 is vertically and correspondingly connected with an inlet at the top of the material containing cylinder 206, and the caliber of the inlet at the top of the guide cylinder 207 is larger than that of the outlet thereof, so that the material bag 4 output from the belt conveyor 301 can be more easily received. When the material bag 4 is discharged from the belt conveyor 301, the material bag 4 is filled with the material, so that the front end of the material bag 4 enters the guide cylinder 207 in a nearly inclined posture, and in order to smoothly receive the material bag 4, an inclined plane is arranged on one side of the guide cylinder 207, which is opposite to the belt conveyor 301, so that the material bag 4 falls down along the inclined plane after entering the guide cylinder 207, the posture is adjusted to be vertical, and finally the material bag enters the material containing cylinder 206 from the guide cylinder 207.

The side wall of the puncture shell 102 is provided with a feed inlet 105, the outer side wall of the puncture shell 102 at the feed inlet 105 is provided with a guide cover 104, the guide cover 104 is L-shaped, the guide cover 104 covers the outer part of the feed inlet 105, the opening of the guide cover 104 is opposite to the puncture direction of the puncture shell 102, and the guide cover 104 and the corresponding feed inlet 105 form a buffer feeding space. The diameter of the circumference enclosed by the air guide sleeve 104 on the puncture shell 102 is not larger than the diameter of the large-diameter end of the puncture head 101, so that the force of the material bag 4 when being punctured mainly acts on the puncture head 101 to protect the air guide sleeve 104. The feed inlets 105 are arranged on the puncture housing 102 in a plurality of rows at intervals along the axial direction of the puncture housing 102, and the number of each row of feed inlets 105 is a plurality and is uniformly arranged along the circumferential direction of the puncture housing 102. The suction pipe 107 is provided with a suction port 106 for allowing the material to flow into the suction pipe 107, and the suction ports 106 on the suction pipe 107 are arranged in one-to-one correspondence with the feed ports 105.

In addition, the penetrating housing 102 may also extend below where it joins the suction tube 107 through the flexible base, with the chute 1082 opening into the penetrating housing 102 below the flexible base.
The driving assembly 1083 includes a triangular driving head and a driving motor (not shown), an output shaft of the driving motor is connected to the driving head, and the driving motor is used for driving the driving head to rotate. When the angle of the driving head rotates to the top, the position of the sliding rod 1081 is at the highest position, the spring 103 is in a compressed state, and the material suction port 106 and the material inlet 105 are dislocated; when the side edge of the driving head rotates to the uppermost position, the position of the sliding rod 1081 is positioned at the lowest position, and at the moment, the suction port 106 is reset to correspond to the feed port 105; therefore, the continuous rotation of the driving head can drive the suction pipe 107 to reciprocate along the axial direction of the driving head, so that the uninterrupted interference on the material state of the feeding hole 105 is realized, and the material is prevented from being blocked at the feeding hole 105 or the suction hole 106.
In addition, the driving component 1083 of the reciprocating mechanism 108 may also be a cam-type component, a slider-crank-type component, or a linear telescopic component, wherein the linear telescopic component may be a mechanism with a telescopic rod, such as an air cylinder, an oil cylinder, or an electric push rod, the telescopic rod is disposed below the sliding rod 1081, the telescopic rod extends out to push the position of the sliding rod 1081 to the highest position, and after the telescopic rod is contracted, the sliding rod 1081 falls back under the combined action of the spring 103 and the gravity of the suction tube 107, so as to drive the suction tube 107 to reciprocate in the puncture housing 102. The reciprocating motion of the cam type component and the crank block type component is the prior art and is not described in detail herein.
As shown in fig. 8, 9, 10, each cartridge (206) is provided with a bag moving assembly by which the aspirated material bag 4 is removed from the cartridge 206. The bag moving assembly comprises a material bag fixing nail 204 and a material bag push rod 205 which are oppositely arranged on two sides of the material containing barrel 206, and the tip end of the material bag fixing nail 204 points to be opposite to the bag moving direction of the material bag push rod 205.

During the operation process of the bag moving assembly, the materials in the material bag 4 are completely sucked and closed to form an empty bag, the material bag push rod 205 pushes the empty bag to push the empty bag out of the material containing barrel 206, and finally the empty bag is punctured by the material bag fixing nail 204 and is sleeved on the material bag fixing nail 204. In the process of ejecting the empty bag by the material bag push rod 205, the lower part of the material bag is separated from the puncture housing 102 and the puncture head 101 due to the pulling of the material bag push rod 205.

The driving mechanism can be configured as an air cylinder or an electric cylinder, and a piston of the driving mechanism is connected with the material bag push rod 205. The distance between the material bag holding barrel 206 and the corresponding partition plate 203 is such that the material bag push rod 205 can move the empty bag completely out of the material bag holding barrel 206, if the distance is too small, a part of the bag body will remain in the material bag holding barrel 206 after the empty bag is inserted on the material bag fixing nail 204, which will affect the moving out of the subsequent material bag 4.
