DETAILED DESCRIPTION

[0027] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] A pneumatic weighing and defective product rejection machine, such as Figure 1 As shown, it includes: a first slide 1 and an inclined plate feeder 2, wherein the inclined plate feeder 2 is used to transport gas bomb bottles arranged in rows, the first slide 1 includes an input end and an output end, and the output end of the inclined plate feeder 2 is connected to the input end of the first slide 1.

[0029] The input end of the first slide 1 is higher than the output end of the first slide 1, so that the gas bomb bottle dropped onto the first slide 1 by the inclined plate feeder 2 can undergo a period of gravity acceleration, so that the gas bomb bottle can fall to the next component at a faster speed.

[0030] The first slide 1 includes a first support plate 101 and a second support plate 102, wherein the first support plate 101 and the second support plate 102 are connected at an obtuse angle, and a recess is formed at the connection. One end of the recess is connected to the output end of the first conveying track 8 of the inclined plate feeder 2, and the other end of the recess is connected to the input end of the second conveying track 3. Since the body of the gas bomb bottle is cylindrical, when the gas bomb bottle enters the first slide 1, the gas bomb bottle slides to the recess by the sliding force and passes through the first slide 1. The gas bomb bottles falling into the first slide 1 are all in the same position, and the setting of the recess also prevents the gas bomb bottle from sliding out of the first slide 1.

[0031] The inclined plate loading machine 2 includes a feeding mechanism 201, a second fixed plate 202 and a first inclined plate 203, and the feeding mechanism 201 can be set as a conveying belt line or a slide plate. When the feeding mechanism 201 is set as a slide plate, the side edge of the slide plate close to the first inclined plate 203 is lower than the side edge of the slide plate away from the first inclined plate 203, so that the gas bomb bottle can slide along the slide plate. When the conveying belt line is set in the horizontal direction, the gas bomb bottle is transported by relying on the conveying force of the conveying belt line. In practical applications, the feeding mechanism 201 can be selected according to demand. When conveying gas bomb bottles in large quantities, a slide plate is preferred so that the gas bomb bottles can slide quickly. When a conveying belt line is preferred to smoothly convey and prevent the gas bomb bottles from bumping, the gas bomb bottle can be smoothly conveyed.

[0032] The second fixing plate 202 of the inclined plate loading machine 2 includes a second limiting side surface 2021 and a second upper side surface 2022. The second limiting side surface 2021 of the second fixing plate 202 is arranged in the vertical direction, and the second upper side surface 2022 is inclined downward from the left side to the right side, so that when the gas bomb bottle is on the second upper side surface 2022, the gas bomb bottle will slide to the right due to its own gravity. Figure 3 , three second fixing plates 202 are provided, each second fixing plate 202 is provided in parallel, and the second upper side surface 2022 of each second fixing plate 202 is at a horizontal plane of different heights, and the horizontal position of each second upper side surface 2022 is higher than the horizontal position of the output end of the feeding mechanism 201. The horizontal heights of the second upper side surfaces 2022 of the three second fixing plates 202 gradually increase from left to right.

[0033] The first inclined plate 203 of the inclined plate loading machine 2 includes a first limiting side surface 2031 and a first upper side surface 2032. The first limiting side surface 2031 is arranged in the vertical direction, and the first upper side surface 2032 is inclined downward from the left side to the right side. When the gas bomb bottle is on the first upper side surface 2032, the gas bomb bottle will slide to the right due to its own gravity.

[0034] The first inclined plate 203 is disposed between the feeding mechanism 201 and the second fixed plate 202 , and a first inclined plate 203 is disposed between every two second fixed plates 202 .

[0035] A first inclined plate 203 is provided between the feeding mechanism 201 and the second fixed plate 202 on the leftmost side. The first inclined plate 203 can move up and down to drive the first upper side surface 2032 to be connected back and forth between the output end of the feeding mechanism 201 and the input end of the second upper side surface 2022. When the first inclined plate 203 is connected to the output end of the feeding mechanism 201, the gas bomb falls from the feeding mechanism 201 to the first inclined plate 203 between the feeding mechanism 201 and the second fixed plate 202, and then the first inclined plate 203 moves upward. Since the first upper side surface 2032 of the first inclined plate 203 is tilted to the lower right, during the upward displacement of the first inclined plate 203, the gas bomb slides to the right due to gravity and hits the second limiting side surface 2021 of the adjacent second fixed plate 202, until the first inclined plate 203 is connected to the input end of the second upper side surface 2022 of the second fixed plate 202, and the gas bomb falls into the second upper side surface 2022 of the second fixed plate 202.

[0036] Multiple sets of the first inclined plate 203 and the second fixed plate 202 can be arranged on the inclined plate loading machine 2, so that the conveying efficiency of the inclined plate loading machine 2 can be increased.

[0037] The inclined plate loading machine 2 also includes a first conveying track 8, which is a conveyor belt. The width of the first conveying track 8 is adapted to the diameter of the gas bomb bottle, so that the direction of the gas bomb bottle remains unchanged when the gas bomb bottle is conveyed along the first conveying track 8. The first conveying track 8 and the first inclined plate 203 are respectively arranged on both sides of the second fixed plate 202. When the gas bomb bottle passes through the second upper side surface 2022 of the second fixed plate 202 and slides into the first conveying track 8, the height of the gas bomb bottle is transported parallel to the conveying direction. The output end of the first conveying track 8 is connected to the input end of the first slide 1, so that the gas bomb bottle conveyed to the first slide 1 is in the same direction.

[0038] The output end of the first slide 1 is connected to the second conveying track 5, and the second conveying track 5 is arranged as a whole on the weighing device 9. The weighing device 9 is used to detect the weight of the second conveying track 5 and the gas bomb bottle. The weight weighed by the weighing device 9 minus the fixed weight of the second conveying track 5 can measure the weight of the gas bomb bottle passing through the second conveying track 5.

[0039] The output end of the second conveying track 5 is connected to the third conveying track 3, and a sorting mechanism 4 is arranged on one side of the third conveying track 3. The third conveying track 3 is arranged as a conveyor belt, and the sorting mechanism 4 is arranged as a push rod controlled and pushed by a cylinder. The sorting mechanism 4 can be pushed horizontally on the third conveying track 3, and the sorting mechanism 4 can push the gas bomb bottle from the third conveying track 3 to the positions on both sides. An unqualified quality box can be arranged at one side of the third conveying track 3 first, and a qualified quality box can be arranged at the output end of the third conveying track 3. When the sorting mechanism 4 detects that the quality of the gas bomb bottle is unqualified, the gas bomb bottle can be pushed to the unqualified quality box on one side of the third conveying track 3.

[0040] Baffles 7 are arranged on both sides of the third conveying track 3. The width of the baffles 7 matches the diameter of the gas bomb bottle, so that the gas bomb bottle passing through the third conveying track 3 can be pushed in the same direction. The sorting mechanism 4 is arranged at the end position of the baffle 7.

[0041] The detection device 6 and the control unit, the detection device 6 is connected to the weighing device 9 by signal, and is used to detect the weight information of the weighing device 9. The control unit is connected to the detection device 6 and the sorting mechanism 4 by signal, and is used to receive the weight information and control the pushing of the sorting mechanism 4 according to the weight information. When the detection device 6 detects that the weight of the gas bomb bottle passing through the weighing device 9 is insufficient, the detection device 6 controls the sorting mechanism 4 to push the gas bomb bottle horizontally toward the third conveying track 3. When the detection device 6 detects that the weight of the gas bomb bottle passing through the weighing device 9 is sufficient, the control device controls the sorting mechanism 4 to remain stationary, so that the gas bomb bottle is continuously conveyed along the third conveying track 3. Moreover, the gas bomb bottles are all transported through the first conveying track 8 and the first slide 1, and the speed at which the gas bomb bottles fall into the third conveying track 3 is consistent. The distance that the gas bomb bottles need to travel from the second conveying track 5 to the sorting mechanism 4 can be determined, so the time for the gas bomb bottles passing through the weighing device 9 to reach the sorting mechanism 4 can be determined by calculation. When the detection device 6 detects that the weighing device 9 shows that the gas bomb bottle is underweight, the detection device 6 feeds back a signal to the sorting mechanism 6. After receiving the feedback information, the sorting mechanism 6 responds by pushing and pushes the gas bomb bottle to one side of the third conveying track.

[0042] Working process: the gas bomb bottle is input from the feeding mechanism 201 until it hits the first limiting side surface 2031 of the first inclined plate 203. When the first upper side surface 2032 of the first inclined plate 203 moves to the output end connected to the feeding mechanism 201, when the center of gravity of the gas bomb bottle falls above the first inclined plate 203, the gas bomb bottle falls to the first upper side surface 2032 of the first inclined plate 203. When the center of gravity of the gas bomb bottle falls to the left of the first inclined plate 203, the gas bomb bottle falls back onto the feeding mechanism 201. The first inclined plate 203 with the gas bomb bottle rises until it is connected to the input end of the second fixed plate 202. The gas bomb bottle slides down to the first conveying track 8 along the second upper side surface 2022 of the second fixed plate 202 by gravity. The first conveying track 8 is connected to the first slideway 1. The gas bomb bottle passing through the first slideway 1 falls on the second conveying track 5 by gravity acceleration. The weighing device 9 weighs the second conveying track 5 and the gas bomb bottle as a whole. When the detection device 6 detects that the weight of the gas bomb bottle passing through the weighing device 9 is insufficient, a feedback signal is sent to the detection device 6. After receiving the feedback information, the sorting mechanism 6 reacts by pushing and pushes the gas bomb bottle to one side of the third conveying track 3. When the detection device 6 detects that the weight of the gas bomb bottle passing through the weighing device 9 is sufficient, the control device controls the sorting mechanism 4 to remain stationary, so that the gas bomb bottle is continuously conveyed along the third conveying track 3. The gas bomb bottle pushed down by the sorting mechanism 4 is a gas bomb bottle of insufficient quality, and the gas bomb bottle continuously conveyed along the third conveying track 3 is a gas bomb bottle of sufficient quality.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
