DETAILED DESCRIPTION

[0030] The present application will be further described in the following examples, but the present application is not limited in the scope of the examples.

[0031] As Figures 1-12 shown, an intelligent suspension conveying system for PVC plate raw material ton bags includes a protective shell 1; a plurality of mounting frames 3 are fixedly installed on the side wall of the protective shell 1 and fixed with external mounting structures through the mounting frames 3 to fixedly install the entire system. It also includes: A translation conveying assembly is installed in the protective shell 1. The electric hoist 6 is fixedly installed with a connecting rod 7 at the top, the connecting rod 7 passes through the long slot 102 arranged at the bottom of the protective shell 1, and the connecting rod 7 is connected with the translation conveying assembly; The shielding assembly 9 is arranged at intervals along the length direction of the long slot 102, and adjacent shielding assemblies 9 are in close contact to block the long slot 102; the shielding assembly 9 is connected with an elastic reset part; The translation conveying assembly is provided with an extrusion strip 15 at the connecting position of the connecting rod 7, which is used for extruding and opening the shielding assembly 9, so that the connecting rod 7 forms a groove 12 at the position of the long slot 102; The blocking cover 10 is slidably sleeved on the connecting rod 7 and located below the groove 12; the blocking cover 10 is connected with a pulling assembly 20; The air supply part is in communication with the top of the protective shell 1 and is used for blowing clean air into the protective shell 1.

[0032] The whole intelligent suspension conveying system is installed above the PVC plate raw material processing equipment; when conveying materials to the feeding hopper of the processing equipment, the electric hoist 6 is lowered to the hook, a ton bag (containing any one of powder materials such as PVC, calcium powder and adjusting agent) is lifted by the forklift, then the ton bag is manually suspended on the hook, the electric hoist 6 lifts the ton bag to a high position, the translation conveying assembly drives the electric hoist 6 and the ton bag to translate, so that the ton bag moves above the feeding hopper, and finally the ton bag is manually broken at the bottom, and the raw materials in the ton bag enter the feeding hopper; after the above feeding, the translation conveying assembly drives the electric hoist 6 to reset to the position of the forklift, away from above the feeding hopper, and then the electric hoist 6 is lowered to the hook to prepare for the conveying of the next ton bag of materials.

[0033] The traditional suspension conveying system can cause dust when discharging the ton bag of materials, and the dust can easily enter the protective shell 1 through the long slot 102; the shielding assembly 9 is used to shield the long slot 102 in the present application, only the position where the connecting rod 7 extends out of the long slot 102 forms the groove 12; and the connecting rod 7 moves to any position of the long slot 102, the extrusion strip 15 moves with the connecting rod 7, the shielding assembly 9 at the position with the groove 12 is reset by the elastic reset part, so that the long slot 102 at this position is shielded and blocked, and the shielding assembly 9 at the position where the connecting rod 7 moves is extruded by the extrusion strip 15, so that the shielding assembly 9 is opened to form the groove 12; in summary, the shielding effect of the long slot 102 is guaranteed, the possibility of dust entering the long slot 102 is reduced, and the translation movement of the connecting rod 7 is not blocked by the extrusion strip 15 which can open the shielding assembly 9.

[0034] Further, by the above, the protective shell 1 only has the groove body 12 in communication with the external air, and the clean airflow is blown into the protective shell 1 by cooperating with the air supply part, and the airflow entering the protective shell 1 is discharged outward through the groove body 12, thereby avoiding dust from entering the groove body 12, and ensuring the dustproof effect in the protective shell 1.

[0035] Further, the plugging cover 10 and the pulling assembly 20 are arranged, when the whole system is not used, the air supply part is in a closed state, the pulling assembly 20 drives the plugging cover 10 to cover the groove body 12 at the plugging connecting rod 7 to plug, so that the long groove 102 is completely in a closed state, and dust is prevented from entering the protective shell 1 in the state that the whole system is not used.

[0036] As shown in Figures 6-8 , the shielding assembly 9 comprises two shielding strips 901; the top surface of each of the two shielding strips 901 is fixedly installed with a movable column 902; the two sides of the long groove 102 are provided with a plurality of movable grooves 101 which are distributed at equal intervals along the length direction; the movable column 902 is in sliding connection with the movable groove 101; the top end of the movable column 902 is fixedly installed with a first top frame 903; and the first top frame 903 is rotatably installed with a roller 904.

[0037] As shown in Figures 8-9 , the elastic reset part comprises a guide column 905 which is fixedly installed on the side wall of the movable column 902; one side of the movable groove 101 is provided with a first guide hole 104 in communication; the guide column 905 is in sliding sleeve connection with the first guide hole 104; the end of the guide column 905 is provided with a recess hole 906; the recess hole 906 is provided with a first spring 907; and the two ends of the first spring 907 are in abutment with the hole wall of the first guide hole 104 and the hole wall of the recess hole 906 respectively.

[0038] As shown in Figure 8 and Figure 9 , the number of the extrusion strips 15 is two, and the two extrusion strips 15 are symmetrically arranged on the top two sides of the connecting rod 7; the shape of the extrusion strip 15 is isosceles trapezoidal; the two ends of the extrusion strip 15 are provided with extrusion inclined surfaces; and the side of the extrusion strip 15 away from the connecting rod 7 is provided with a side groove 1501.

[0039] As shown in Figure 10 , the length of the extrusion strip 15 is greater than the width of the connecting rod 7, and the two ends of the extrusion strip 15 protrude from the two sides of the connecting rod 7; when the connecting rod 7 is translated, the extrusion strip 15 moves together with the connecting rod 7, and the part of the extrusion strip 15 protruding first extrudes and opens the shielding assembly 9, so as to ensure the smooth entry of the subsequent connecting rod 7 without being blocked.

[0040] Specifically, when the connecting rod 7 drives the extrusion bar 15 to move, the extrusion bevel of the extrusion bar 15 squeezes the roller 904 of the shielding assembly 9, so that the roller 904, the first top frame 903, the movable column 902 and the shielding bar 901 move together, and the movable column 902 slides in the movable groove 101, and the movable column 902 moves, and is guided by the guide column 905 and the first guide hole 104, while compressing the first spring 907. After the above movement, the two shielding bars 901 of the shielding assembly 9 are stretched open; the connecting rod 7 continues to move as described above, and the roller 904 enters the lateral plane of the extrusion bar 15 (that is, the part between the extrusion bevels at both ends of the extrusion bar 15) through the extrusion bevel, and keeps the shielding bar 901 in the stretched state. Figure 10 As shown, when the connecting rod 7 moves to any position of the long slot 102 , the shielding components 9 at the connecting rod 7 will be stretched open by the extrusion strips 15 to form the slot body 12 .

[0041] When the extrusion bar 15 moves and separates from the roller 904 of the shielding assembly 9, the shielding assembly 9 is reset by the elastic force of the first spring 907, and the two shielding bars 901 are closed again, closing the long slot 102 at this position.

[0042] The roller 904 contacts the extrusion strip 15 , and no matter on the extrusion slopes at both ends or on the plane between the two extrusion slopes, the roller 904 is located in the side groove 1501 , that is, the roller 904 slides with the side groove 1501 .

[0043] It should be noted that if Figure 9 As shown, the shielding strip 901 always covers and shields the movable slot 101 ; when the shielding strip 901 is stretched or blocks the long slot 102 , the movable slot 101 is closed to prevent dust from entering the protective shell 1 through the movable slot 101 .

[0044] like Figure 11 As shown, a first rubber ring 1002 is installed at the bottom end of the blocking cover 10, a top ring 1003 is fixedly installed on the inner wall of the top end of the blocking cover 10, and a second rubber ring 1004 is installed on the inner ring of the top ring 1003. The first rubber ring 1002 and the second rubber ring 1004 are both tightly fitted with the connecting rod 7, and a blocking plate 1001 is provided at the top of the blocking cover 10.

[0045] A closed annular cavity is formed by the sealing cover 10 , the first rubber ring 1002 , the top ring 1003 , the second rubber ring 1004 and the wall of the connecting rod 7 , and the annular cavity always surrounds the vertical groove 703 to prevent dust from entering the vertical groove 703 .

[0046] The interior of the connecting rod 7 is provided with an inner cavity 701, and one side of the connecting rod 7 is provided with a vertical groove 703 and a second guide hole 702 communicating with the inner cavity 701, and the vertical groove 703 is located inside the blocking cover 10; the pull-up assembly 20 is installed in the inner cavity 701, and the pull-up assembly 20 includes a guide wheel 2002 rotatably installed in the inner cavity 701; a pull rope 2003 is passed around the guide wheel 2002, and a second pressure column 2001 is fixed to one end of the pull rope 2003, and the second pressure column 2001 is slidably sleeved with the second guide hole 702, and the second pressure column 20 One end of 01 extends to the outside of the inner cavity 701, and a movable bar 2004 is fixed to the bottom end of the pull rope 2003. The movable bar 2004 passes through the vertical slot 703, and the movable bar 2004 is fixed to the inner wall of the blocking cover 10. A guide column 2005 is fixedly installed on the bottom surface of the inner cavity 701. The guide column 2005 is slidably connected with the guide sleeve 2006 set on the movable bar 2004. A third spring 2007 is sleeved on the guide column 2005, and the top of the guide column 2005 and the guide sleeve 2006 are elastically connected by the third spring 2007.

[0047] The upper pulling component 20 is used to drive the blocking cover 10 to move up and down, and is used to open or block the slot body 12. When the entire system is not in use, the slot body 12 is blocked to completely block the long slot 102, thereby ensuring the dust-proof effect of the protective shell 1 when the air supply part is closed; when in use, the blocking cover 10 is separated from the slot body 12, and the blocking cover 10 moves together with the connecting rod 7, and the blocking cover 10 will not cause friction or wear with the shielding strip 901.

[0048] The specific operation of the pull-up assembly 20 is as follows: Figure 11 As shown, at this time, the pulling assembly 20 does not drive the blocking cover 10 to move upward, and the blocking cover 10 does not block the slot body 12; when the slot body 12 is blocked, the connecting rod 7 is moved to the left, and the second pressure column 2001 approaches the inner wall of the protective shell 1 until the connecting rod 7 moves to the leftmost side. The second pressure column 2001 is squeezed by the left inner wall of the protective shell 1, so that the second pressure column 2001 drives the top of the pull rope 2003 to move to the right, and the pull rope 2003 is guided by the guide wheel 2002 to pull the movable bar 2004 upward, and the movable bar 2004 drives the blocking cover 10 to move upward until the baffle 1001 on the blocking cover 10 blocks and covers the slot body 12, completing the closure, and in the process of the blocking cover 10 moving upward, the sliding between the guide sleeve 2006 and the guide column 2005 provides guidance, and at the same time compresses the third spring 2007.

[0049] When the connecting rod 7 drives the second pressure column 2001 to separate from the left inner wall of the protective shell 1, the compressive elastic force of the third spring 2007 drives the movable bar 2004 and the blocking cover 10 to move downward and reset, and the second pressure column 2001 is pulled back to its original position by the pull rope 2003. Figure 11The state is shown.

[0050] Through the above design, the up-pulling assembly 20 drives the sealing cover 10 to move up and down without additional power source, and moves to the side wall of the protective shell 1 through the connecting rod 7, so that the side wall extrudes the second pressing column 2001 to provide power.

[0051] As Figure 1 shown, the air supply part includes an air inlet 4 fixedly communicated to the top of the protective shell 1, the air inlet 4 is fixedly communicated with an air supply pipe 5, and the air supply pipe 5 is connected with a fan (not shown in the figure). The fan is arranged away from the PVC plate raw material processing equipment, and the fan is arranged in a clean air environment, and the air inlet 4 of the fan is provided with a filtering device to ensure the cleanliness of the air entering the fan.

[0052] The fan blows clean air into the protective shell 1 through the air supply pipe 5 and the air inlet 4, and the air is blown out from the groove body 12 after passing through the protective shell 1, so as to prevent dust from entering the protective shell 1 from the groove body 12.

[0053] It also includes an oil injection assembly 19; the oil injection assembly 19 is connected with a cavity opened in the extrusion strip 15, a plurality of oil outlet holes 1502 are arranged at the top edge of the side groove 1501 in the length direction, and the oil outlet holes 1502 are communicated with the cavity.

[0054] The oil injection assembly 19 is used for injecting lubricating oil into the cavity in the extrusion strip 15, the oil enters the plurality of oil outlet holes 1502 through the cavity, is uniformly dispersed at the top edge in the length direction of the side groove 1501, and flows downward to the lower side of the side groove 1501, so that the side groove 1501 uniformly has lubricating oil. Lubrication is provided between the roller 904 and the side groove 1501 to reduce friction.

[0055] As Figure 1 , Figure 2 , Figure 7 and Figure 11 shown, the translation conveying assembly includes a motor 2 fixedly installed on one end wall of the protective shell 1 and a screw rod 13 rotatably installed in the protective shell 1; one end of the screw rod 13 is fixedly connected with the output shaft end of the motor 2, a nut seat 17 is threadedly connected on the screw rod 13, the nut seat 17 is fixedly connected with a connecting seat 14, the bottom of the connecting seat 14 is fixedly connected with the extrusion strip 15, and the bottom of the extrusion strip 15 is fixedly connected with the connecting rod 7 through the second top frame 16.

[0056] The bottom of the second top frame 16 is provided with a traveling wheel 18, a sliding groove 103 is formed in the inner wall of the bottom of the protective shell 1, and the traveling wheel 18 is slidably connected with the sliding groove 103.

[0057] The motor 2 drives the screw 13 to rotate, which is transmitted by the thread of the screw 13 and the nut seat 17, and guided by the sliding between the walking wheel 18 and the slide groove 103, so that the nut seat 17, the connecting seat 14, the extrusion bar 15, the second top frame 16 and the connecting rod 7 are translated together to drive the electric hoist 6 to move in translation.

[0058] like Figure 11 As shown, the oil filling assembly 19 includes a fixing frame 1901 fixedly mounted to the side of the second top frame 16; a cylinder 1902 is fixedly mounted on the fixing frame 1901, and a piston 1906 is connected in cooperation with the cylinder 1902, and the piston 1906 is fixedly mounted with a first pressure column 1903, and the first pressure column 1903 extends out of the cylinder 1902, and one side of the piston 1906 and the inner wall of the cylinder 1902 form an oil filling chamber, and a second spring 1907 is provided in the oil filling chamber; two one-way valves 1908 are installed at one end of the cylinder 1902, and one end of the two one-way valves 1908 is connected to the oil filling chamber, and the two one-way valves 1908 are respectively connected to a first connecting pipe 1904 and a second connecting pipe 1905, the first connecting pipe 1904 is connected to the oil storage chamber 1402 provided in the connecting seat 14, and the second connecting pipe 1905 is connected to the cavity in the extrusion strip 15.

[0059] When the connecting rod 7 moves to the right, the first pressure column 1903 approaches the inner wall of the protective shell 1 until the connecting rod 7 moves to the far right. The first pressure column 1903 is squeezed by the left inner wall of the protective shell 1. The first pressure column 1903 drives the piston 1906 to squeeze the oil in the oil filling chamber. The oil enters the second connecting pipe 1905 through a one-way valve 1908, and then enters the cavity in the extrusion bar 15 to achieve oil filling. In the above process, the second spring 1907 is compressed.

[0060] The connecting rod 7 drives the first pressure column 1903 to separate from the right side wall of the protective shell 1. The elastic force of the second spring 1907 resets the piston 1906 and the first pressure column 1903, and the oil filling chamber is sucked, so that the oil in the oil storage chamber 1402 enters the oil filling chamber through the first connecting pipe 1904 and the one-way valve 1908.

[0061] Through the above design, lubricating oil is automatically injected into the side groove 1501 to achieve automatic lubrication.

[0062] It should be noted that when the electric hoist 6 is moved to above the feed hopper of the PVC sheet raw material processing equipment, or moved to the position where the ton bag is assisted to be hung on the electric hoist 6 by a forklift, the first pressure column 1903 and the second pressure column 2001 are not in contact with the inner wall of the protective shell 1, that is, the entire system is in operation, and in the process of conveying ton bags, the electric hoist 6 is switched between the above two positions, and the pulling component 20 and the oil injection component 19 will not be driven.

[0063] In order to drive the pulling assembly 20 and the oiling assembly 19, the connecting rod 7 needs to be specially moved to the leftmost side and the rightmost side, so that the inner wall of the protective shell 1 extrudes the first pressing column 1903 and the second pressing column 2001 to realize driving.

[0064] The top of the protective shell 1 is provided with an access hole, and a sealing plate 8 is installed on the access hole through screws. The top of the connecting seat 14 is provided with a filling port communicated with the oil storage cavity 1402, and a sealing cover 1401 is installed on the filling port.

[0065] When the oil storage cavity 1402 needs to be filled, the connecting seat 14 is moved to below the access hole, and the filling operation is performed through the access hole by removing the sealing plate 8, and the filling operation is performed through the filling port by removing the sealing cover 1401.
