[0037] Reference Figure 1 In the anti-stacking material pushing structure of the first aspect embodiment of the present application, a rack 100, a pressing plate 115 and a material blocking device 120 are provided, an inclined material discharging channel 101 is provided, an inlet 102 is provided at the top end of the material discharging channel 101, a discharging cavity 103 is provided at the bottom end of the material discharging channel 101, and the material discharging channel 101 is communicated with the discharging cavity 103. It can be understood that the pipe material 104 can enter the material discharging channel 101 from the inlet 102 and move to the discharging cavity 103 under the action of gravity, and the discharging cavity 103 has a conveying device to convey the pipe material 104 into the processing equipment.

[0038] It can be understood that the pressing plate 115 is movably connected to the frame 100, and the pressing plate 115 can move along a direction perpendicular to the movement direction of the pipe 104 in the discharging channel 101, and the height of the discharging channel 101 can be adjusted when the pressing plate 115 is adjusted. It can be understood that the height direction of the discharging channel 101 is perpendicular to the movement direction of the pipe 104 in the discharging channel 101. The pressing plate 115 adjusts the height of the discharging channel 101, so that the pipes 104 in the discharging channel 101 cannot be stacked, the pipes 104 are discharged one by one, and the pipes 104 are prevented from being stacked in the discharging channel 101 or the discharging cavity 103, and even from being jammed.

[0039] Specifically, the frame 100 is provided with a first adjusting device 110, the first adjusting device 110 includes an adjusting rod 112 connected to the pressing plate 115 and an adjusting mechanism 116, and the adjusting rod 112 is connected to the adjusting mechanism 116. In this embodiment, the adjusting mechanism 116 is a worm gear transmission machine, and a hand wheel 105 is arranged on the adjusting mechanism 116. The position of the pressing plate 115 on the frame 100 is adjusted by manual operation, which can save equipment cost. In other embodiments, the adjusting mechanism 116 can be driven by a servo motor, which is beneficial to improve the automation level and reduce manual operation.

[0040] It can be understood that the blocking device 120 arranged below the discharging channel 101 includes a first blocking rod 121 and a second blocking rod 122 movably connected to the frame 100. The first blocking rod 121 is located at one end of the discharging channel 101 provided with the inlet 102, and the second blocking rod 122 is located at one end of the discharging channel 101 close to the discharging cavity 103. When the first blocking rod 121 descends, the pipe 104 can fall along the discharging channel 101 and abut against the second blocking rod 122. It can be understood that the first blocking rod 121 and the counter-pushing air cylinder 125 together ensure that a single pipe 104 enters the discharging channel 101, and the second blocking rod 122 is used to place the pipe 104 ready to be fed, so as to prevent the pipes 104 from being stacked in the discharging cavity 103.

[0041] It can be understood that the pressing plate 115 is provided with a fixedly installed counter-pushing air cylinder 125, which can extend towards the inlet 102, so as to remove the stacked pipes 104 at the inlet 102. Specifically, a pushing block 126 is installed on the piston rod of the counter-pushing air cylinder 125, and the pushing block 126 is provided with a baffle 127 parallel to the extension direction of the piston rod. The baffle 127 is located at the side of the counter-pushing air cylinder 125 close to the discharging channel 101. When the counter-pushing air cylinder 125 extends, the pushing block 126 pushes outwards, so as to eliminate the stacking of the pipes 104.

[0042] Referring to Figure 2It can be understood that when the pipe 104 enters the discharge passage 101 from the inlet 102, the first blocking rod 121 can block the pipe 104, and two pipes 104 can be stacked in a random manner, such as Figure 2 As shown, two pipes 104 are stacked along the height direction of the discharge passage 101. Since the pressing plate 115 has been positioned, the height of the discharge passage 101 is slightly larger than the width of the pipe 104. Therefore, when the width-to-height ratio of the pipe 104 is 2:1, two pipes 104 stacked along the height direction of the discharge passage 101 can enter the discharge passage 101, thereby causing blockage. It can be understood that when the push block 126 is extended by the action of the reverse push cylinder 125, the pipe 104 on the upper layer can be pushed out by the push block 126, so as to ensure that a single pipe 104 enters the discharge passage 101 and ensure smooth conveying of the pipe 104.

[0043] Referring to Figure 3 In another case, two pipes 104 are stacked along the length direction of the discharge passage 101. It can be understood that the first blocking rod 121 serves to separate the pipes 104 and ensure that a single pipe 104 enters the discharge passage 101, but the detection of the pipe 104 generally uses a photoelectric sensor. When two pipes 104 are stacked, the electrical signal of the sensor does not change, so that the two stacked pipes 104 can enter the discharge passage 101 at the same time, thereby causing blockage. Therefore, when the push block 126 is extended by the action of the reverse push cylinder 125, the pipe 104 on the outer side can be pushed out by the push block 126, so as to ensure that a single pipe 104 enters the discharge passage 101 and ensure smooth conveying of the pipe 104.

[0044] Referring to Figure 2 Since the pressing plate 115 can move along a direction perpendicular to the movement direction of the pipe 104 in the discharge passage 101, and the bottom wall of the pressing plate 115 is parallel to the length direction of the discharge passage 101. It can be understood that the wall surface of the blocking plate 127 and the bottom wall of the pressing plate 115 have an included angle R, which satisfies: 15°≤R≤20°.

[0045] It can be understood that when the included angle R between the wall surface of the baffle 127 and the bottom wall of the pressing plate 115 is less than 15°, the included angle between the extension direction of the push block 126 and the length direction of the discharge channel is too small, and the push block 126 is difficult to push the pipe 104 located on the outer side or the upper layer when it extends, so that it is difficult to eliminate the stacking phenomenon, thereby causing the pipe to be blocked. When the included angle R between the wall surface of the baffle 127 and the bottom wall of the pressing plate 115 is greater than 20°, the included angle between the extension direction of the push block 126 and the length direction of the discharge channel is too large, so that the push block 126 is easy to push out two stacked pipes 104 at the same time when it extends, resulting in the pipe being unable to be fed. Therefore, only when the included angle R satisfies 15°≤R≤20°, the stable effect of eliminating the stacking phenomenon of the pipe 104 can be ensured, and the situation of blocking the pipe is avoided.

[0046] With reference to Figure 4 and Figure 5 It can be understood that the first stop rod 121 and the second stop rod 122 are arranged in sequence along the moving direction of the pipe 104. It can be understood that the stop device 120 comprises a first lifting cylinder 128 and a second lifting cylinder 129, the first lifting cylinder 128 is used to drive the first stop rod 121 to move, and the second lifting cylinder 129 is used to drive the second stop rod 122 to move. It can be understood that the extension direction of the first stop rod 121 and the second stop rod 122 is perpendicular to the length direction of the discharge channel 101.

[0047] Further, the stop device 120 comprises a sliding plate 123, which is slidingly connected to the rack 100 and can move along the length direction parallel to the discharge channel 101. It can be understood that the first lifting cylinder 128 and the second lifting cylinder 129 are installed on the sliding plate 123, and the sliding plate 123 is provided with a second sliding rail 130, the second stop rod 122 is slidingly connected to the second sliding rail 130, the second sliding rail 130 can guide the second stop rod 122 and can bear the impact of the pipe 104 falling, so as to avoid the damage of the second lifting cylinder 129, and is beneficial to improve the stability of operation.

[0048] Further, the rack 100 is provided with a second adjusting device 111, the second adjusting device 111 comprising an adjusting mechanism 116 and an adjusting shaft 113, the sliding plate 123 is provided with a rack 124, the adjusting shaft 113 is provided with a gear 114 engaged with the rack 124, the adjusting mechanism 116 can drive the adjusting shaft 113 to rotate, thereby driving the sliding plate 123 to move along the height direction of the discharging channel 101 through the engagement of the gear 114 and the rack 124, so as to adjust the positions of the first stop lever 121 and the second stop lever 122 in the discharging channel 101. At the same time, the rack 100 is provided with a first sliding rail 117, the sliding plate 123 is slidingly connected to the first sliding rail 117, so as to adjust the position of the sliding plate 123. It can be understood that in the embodiment, the adjusting mechanism 116 of the second adjusting device 111 is provided with the hand wheel 105 and adjusts the position of the sliding plate 123 in a manual manner. In other embodiments, the adjusting mechanism 116 of the second adjusting device 111 can be driven by a servo motor.

[0049] According to the embodiment of the second aspect of the utility model, a feeding machine is provided, comprising the anti-stacking pushing structure. It can be understood that the feeding machine comprises all the technical features of the anti-stacking pushing structure, and therefore the feeding machine at least has all the beneficial effects of the anti-stacking pushing structure.
