[0029] The bottom plate 101 is provided with two conveying assemblies, which are symmetrically arranged on both sides of the transposition gear 118. The conveying assemblies include a conveying bottom plate 102 and a lifting gear 117. The conveying bottom plate 102 is slidably installed on the bottom plate 101. A spring is arranged between the conveying bottom plate 102 and the bottom plate 101. The conveying bottom plate 102 is provided with a conveying group 103. The conveying group 103 includes two conveying rollers and a conveying belt. The two conveying rollers in the conveying group 103 are rotatably installed on the corresponding conveying bottom plate. 102, two conveying rollers in the conveying group 103 are connected by the conveying belt in the conveying group 103, and a conveying motor 114 is fixedly installed on the conveying base plate 102. The output shaft of the conveying motor 114 is fixedly connected to the corresponding conveying roller. A lifting screw 116 is fixedly installed on the conveying base plate 102, and a lifting gear 117 is rotatably installed on the base plate 101. The lifting screw 116 and the lifting gear 117 form a spiral pair, and the lifting gear 117 is meshed with the transposition gear 118 to form a gear pair.

[0030] In the initial position, the conveying bottom plate 102 is located at the position closest to the bottom plate 101, and the torsion spring between the position-changing gear 118 and the position-adjusting rotating frame 113 is not compressed.

[0031] The shifting motor 115 is started to drive the transmission gear 119 to rotate. Under the action of the torsion spring between the position adjustment rotating frame 113 and the shifting gear 118, the position adjustment rotating frame 113 and the lifting gear 117 rotate synchronously. The lifting gear 117 rotates to move the lifting screw rod 116 upward, that is, the conveying bottom plate 102 moves upward, and the spring between the conveying bottom plate 102 and the bottom plate 101 is compressed, and finally the position adjustment rotating frame 113 contacts the end of one end of the limiting strip 120. At this time, the position adjustment rotating frame 113 is located between the two conveying bottom plates 102. 2, under the action of the limiting strip 120, the adjusting rotary frame 113 cannot continue to rotate, the shifting gear 118 continues to rotate, and the torsion spring between the shifting gear 118 and the adjusting rotary frame 113 is compressed, so that the conveying bottom plate 102 continues to move upward, and the shifting motor 115 is started to drive the shifting gear 118 to rotate in the opposite direction, so that the adjusting rotary frame 113 contacts the end of the other end of the limiting strip 120. At this time, the adjusting rotary frame 113 is located directly above the other conveying bottom plate 102.

[0032] A positioning slide 123 is slidably mounted on the positioning turret 113, a positioning screw rod 121 is rotatably mounted on the positioning turret 113, the positioning screw rod 121 and the positioning slide 123 constitute a spiral pair, a positioning motor 122 is fixedly mounted on the positioning turret 113, the output shaft of the positioning motor 122 is fixedly connected to the positioning screw rod 121, a fan-shaped side plate 124 is fixedly mounted on the positioning slide 123, an extrusion slide 139 is slidably mounted on the fan-shaped side plate 124, a spring is arranged between the fan-shaped side plate 124 and the extrusion slide 139, a fan-shaped strip plate 110 is symmetrically rotatably mounted on the positioning slide 123, and a complete circle is formed when the two fan-shaped strip plates 110 and the fan-shaped side plate 124 are engaged.

[0033] A positioning push plate 125 is slidably mounted on the fan-shaped side plate 124, an extrusion screw rod 141 is rotatably mounted on the positioning slide plate 123, the extrusion slide frame 139 and the extrusion screw rod 141 constitute a spiral pair, an extrusion motor 140 is fixedly mounted on the positioning slide plate 123, the output shaft of the extrusion motor 140 is fixedly connected to the extrusion screw rod 141, positioning gears 127 are fixedly mounted on the fan-shaped strip plates 110, and positioning racks 126 are symmetrically slidably mounted on the positioning push plate 125, that is, two positioning racks 126 are arranged opposite to each other, springs are arranged between the positioning racks 126 and the positioning push plate 125, and the positioning racks 126 are meshed with the corresponding positioning gears 127 to constitute a gear rack pair.

[0034] In the initial position, the fan-shaped strip 110 is not in contact with the fan-shaped side plate 124, and the two fan-shaped strips 110 are also not in contact. The spring between the extrusion slide 139 and the fan-shaped side plate 124 and the spring between the adjustment rack 126 and the adjustment push plate 125 are not compressed. The adjustment push plate 125 is located at the farthest position from the adjustment gear 127. At this time, the extrusion screw 141 and the extrusion slide 139 are not in contact.

[0035] Start the extrusion motor 140 to drive the extrusion screw 141 to rotate, so that the adjustment push plate 125 moves in the direction close to the adjustment gear 127. Under the action of the spring between the adjustment push plate 125 and the adjustment rack 126, the adjustment rack 126 moves synchronously, and then the two adjustment racks 126 respectively drive the corresponding adjustment gears 127 to rotate, so that the two sector plates 110 are rotated. Since the two adjustment racks 126 are relatively arranged, the rotation directions of the two adjustment gears 127 are opposite, so that the two sector plates 110 rotate in the direction close to each other, and finally one end of the same sector plate 110 contacts the sector side plate 124, and the other end contacts the end of the other sector plate 110. At this time, a complete circle is formed between the two sector plates 110 and the sector side plates 124. The positioning push plate 125 contacts the end face of the extrusion slide 139, and at this time, the spring between the extrusion slide 139 and the fan-shaped side plate 124 and the spring between the adjustment rack 126 and the positioning push plate 125 are not compressed. The extrusion screw 141 continues to rotate, so that the adjustment push plate 125 continues to move toward the direction close to the adjustment gear 127, and the extrusion slide 139 moves synchronously, and the spring between the extrusion slide 139 and the fan-shaped side plate 124 is compressed. Since the two fan-shaped strips 110 and the fan-shaped side plates 124 form a complete circle, that is, the fan-shaped strips 110 cannot continue to rotate, that is, the adjustment gear 127 cannot continue to rotate, and then the adjustment rack 126 cannot continue to move. Therefore, at this time, the adjustment push plate 125 moves relative to the adjustment rack 126, and the spring between the adjustment push plate 125 and the adjustment rack 126 is compressed.

[0036] An extrusion slide 128 is slidably installed on the fan-shaped strip 110, and a spring is arranged between the extrusion slide 128 and the corresponding fan-shaped strip 110. An extrusion rod 112 is fixedly installed at the ends of the extrusion slide 128 and the extrusion slide 2 139. In the initial position, the spring between the extrusion slide 128 and the fan-shaped strip 110 and the spring between the extrusion slide 2 139 and the fan-shaped side plate 124 are not compressed. The extrusion rod 112 on the extrusion slide 128 is located at the position closest to the fan-shaped strip 110, and the extrusion rod 112 on the extrusion slide 2 139 is located at the position closest to the fan-shaped side plate 124.

[0037] The side surfaces of the fan-shaped strips 110 are rotatably installed with adjustment rotating plates 130, and the extrusion slide 128 is fixedly provided with adjustment short rods 129, and the adjustment short rods 129 are movably connected with the corresponding adjustment rotating plates 130. The side surfaces of the fan-shaped strips 110 are fixedly provided with support straight plates 135, and the support straight plates 135 are slidably installed with trapezoidal slides 133. The end of the adjustment rotating plates 130 is fixedly provided with adjustment push rods 131, and the trapezoidal slides 133 are used to push the adjustment push rods 131 to move. The end of the support straight plates 135 is fixedly provided with limit blocks 136, and the limit blocks 136 are used to limit the position of the trapezoidal slides 133.

[0038] In the initial position, under the action of the extrusion slide 128, the adjustment rotating plate 130, the adjustment rotating plate 130, and the adjustment push rod 131, the trapezoidal slide 133 is located at the farthest position from the corresponding extrusion rod 112, and the trapezoidal slide 133 contacts the limit block 136.

[0039] The positioning slide 123 is symmetrically fixed with support strips 134, and fan-shaped support plates 138 are slidably installed on the support strips 134. The trapezoidal slide 133 and the fan-shaped support plates 138 are movably connected. The fan-shaped support plates 138 and the corresponding positioning gears 127 have the same circumferential direction. There is friction between the fan-shaped support plates 138 and the support strips 134. The ends of the fan-shaped support plates 138 are provided with positioning push blocks 137. The positioning push plates 125 can be used to push the positioning push blocks 137 to move, and the fan-shaped support plates 138 and the support straight plates 135 are not in contact.

[0040] When the positioning push plate 125 contacts the end face of the extrusion slide 139, the positioning push plate 125 and the positioning push block 137 come into contact. At this time, the positioning push plate 125 pushes the extrusion slide 139 to move. Under the action of the positioning short rod 129, the positioning rotating plate 130, the positioning push rod 131, and the trapezoidal slide 133, the displacements of the extrusion slide 128 and the extrusion slide 139 are equal.

[0041] In the initial position, the end face of the adjustment push block 137 farthest from the adjustment gear 127 and the end face of the extrusion slide 139 farthest from the adjustment gear 127 are on the same plane. Under the action of the friction between the support strip 134 and the fan-shaped support plate 138, the fan-shaped support plate 138 will not move when the fan-shaped support plate 138 is not subjected to external force.

[0042] The extrusion motor 140 is started to drive the adjustment push plate 125 to move in the direction close to the adjustment gear 127, so that the fan-shaped strips 110 rotate in the direction close to each other. When the fan-shaped strips 110 rotate, the extrusion rod 112, the extrusion slide 128, the adjustment short rod 129, the adjustment rotating plate 130, the adjustment push rod 131, the trapezoidal slide 133, the support straight plate 135, and the limit block 136 on the fan-shaped strip 110 rotate synchronously, and the trapezoidal slide 133 moves on the fan-shaped support plate 138. The fan-shaped support plate 138 will not move due to the friction between the support strip 134 and the fan-shaped support plate 138. Finally, when the two fan-shaped strips 110 and the fan-shaped side plate 124 form a complete circle, the side of the support straight plate 135 is parallel to the side of the support strip 134. At this time, when the trapezoidal slide plate 133 slides relative to the support straight plate 135, the sliding direction of the trapezoidal slide plate 133 on the support straight plate 135 is the same as the sliding direction of the extrusion slide 139 on the fan-shaped side plate 124.

[0043] Start the extrusion motor 140 to drive the extrusion screw rod 141 to rotate so that the two fan-shaped strips 110 and the supporting circular plate 104 are connected to form a complete circle. At this time, the adjustment push plate 125 contacts the second extrusion slide 139, and the adjustment push plate 125 contacts the adjustment push block 137. The adjustment push plate 125 continues to slide, so that the second extrusion slide 139 and the adjustment push block 137 slide synchronously, that is, the fan-shaped support plate 138 overcomes the friction between the support strip 134 and the fan-shaped support plate 138 and slides synchronously. Since the trapezoidal slide plate 133 and the fan-shaped support plate 138 are movably connected, under the action of the fan-shaped support plate 138, the trapezoidal slide plate 133 slides synchronously at this time. Under the action of the trapezoidal slide plate 133, the adjustment push rod 131 at the end of the adjustment rotating plate 130 moves away from the fan-shaped strip 110, thereby making The other end of the adjustment rotating plate 130 moves toward the direction close to the fan-shaped strip 110, thereby causing the adjustment short rod 129 to move toward the direction close to the fan-shaped strip 110, and the extrusion slide 128 moves synchronously. The spring between the extrusion slide 128 and the fan-shaped strip 110 is compressed, which causes the extrusion rod 112 to move toward the direction close to the axis of the complete circular ring formed by the two fan-shaped strips 110 and the fan-shaped side plate 124. Under the action of the adjustment short rod 129, the adjustment rotating plate 130, the adjustment push rod 131, and the trapezoidal slide 133, the displacement of the extrusion slide 128 toward the direction close to the axis of the complete circular ring formed by the two fan-shaped strips 110 and the fan-shaped side plate 124 is equal to the displacement of the extrusion slide 139 toward the direction close to the axis of the complete circular ring formed by the two fan-shaped strips 110 and the fan-shaped side plate 124.

[0044] The bottom plate 101 is provided with an auxiliary component, which includes a supporting circular plate 104 and an L-shaped slide plate 108 slidably mounted on the bottom plate 101. A supporting motor 105 is fixedly mounted on the bottom plate 101, and the piston rod end of the supporting motor 105 is fixedly connected to the lower surface of the supporting circular plate 104. An auxiliary screw rod 109 is rotatably mounted on the bottom plate 101, and the L-shaped slide plate 108 and the auxiliary screw rod 109 constitute a spiral pair. An auxiliary motor 111 is fixedly mounted on the bottom plate 101, and the output shaft of the auxiliary motor 111 is fixedly connected to the auxiliary screw rod 109. A pressing circular plate 106 is fixedly installed at the end of the sliding plate 108, and an air pump 107 and an air pressure sensor 132 are fixedly installed on the pressing circular plate 106. The air pump 107 and the air pressure sensor 132 are used to detect the air tightness of the plastic barrel. The axes of the supporting circular plate 104 and the pressing circular plate 106 are in the same straight line. When the two fan-shaped strips 110 and the fan-shaped side plates 124 form a complete circular ring, the axis of the complete circular ring formed by the two fan-shaped strips 110 and the fan-shaped side plates 124 and the axis of the supporting circular plate 104 are in the same straight line.

[0045] A plurality of cameras are fixedly mounted on the bottom plate 101 , and the cameras are used to monitor whether the plastic barrel is deformed during the inspection process.

[0046] Working principle: In the initial position, the fan-shaped side plate 124 faces the axial direction of the supporting circular plate 104, and the supporting motor 105 is started to move the supporting circular plate 104 to the position closest to the pressing circular plate 106. At this time, the upper surface of the supporting circular plate 104 is above the upper surface of the conveyor belt in the conveying group 103. At this time, the two fan-shaped strips 110 are located at the farthest position from the axis of the supporting circular plate 104, so as to facilitate the placement of plastic barrels on the supporting circular plate 104.

[0047] Then, the plastic barrel to be tested is placed on the supporting circular plate 104. At this time, the plastic barrel is located between the two fan-shaped strips 110. According to the size of the plastic barrel to be tested, the positioning motor 122 is started to drive the positioning screw 121 to rotate, and the position of the positioning slide 123 on the positioning rotating frame 113 is adjusted, so that the three extrusion rods 112 are located in the middle position of the plastic barrel to be tested. Then, the extrusion motor 140 is started to drive the extrusion screw 141 to rotate, so that the positioning push plate 125 moves toward the direction close to the axis of the supporting circular plate 104. Under the action of the positioning rack 126 and the positioning gear 127, the two fan-shaped strips 110 and the fan-shaped side plate 124 form a complete ring. At this time, the positioning push plate 125 contacts the positioning push block 137 and the extrusion slide 139, the adjustment push plate 125 continues to move, the adjustment push block 137 and the extrusion slide 139 move synchronously, and under the action of the adjustment short rod 129, the adjustment rotating plate 130, the adjustment push rod 131, the trapezoidal slide 133, the adjustment push block 137, and the fan-shaped supporting plate 138, the extrusion slide 128 and the extrusion slide 139 move synchronously, so that the three extrusion rods 112 are all moved in the direction close to the axis of the supporting circular plate 104, and finally the three extrusion rods 112 are all in contact with the side of the plastic barrel placed on the supporting circular plate 104, and the position of the plastic barrel is adjusted under the action of the three extrusion rods 112. At this time, the axis of the plastic barrel and the axis of the supporting circular plate 104 are on the same straight line.

[0048] Then start the auxiliary motor 111 to drive the auxiliary screw 109 to rotate, so that the L-shaped slide plate 108 moves toward the direction close to the supporting circular plate 104, that is, the pressing circular plate 106 moves toward the direction close to the supporting circular plate 104, and finally the lower surface of the pressing circular plate 106 contacts the upper surface of the plastic barrel placed on the supporting circular plate 104. At this time, a sealed chamber is formed between the plastic barrel and the pressing circular plate 106, and air is injected into the sealed chamber formed between the plastic barrel and the pressing circular plate 106 by the air pump 107 to pressurize it. The air pressure sensor 132 monitors the changes in the internal air pressure of the sealed chamber formed between the plastic barrel and the pressing circular plate 106, thereby realizing the detection of the air tightness of the plastic barrel.

[0049] If the air tightness of the plastic barrel is unqualified after detection, the support motor 105 and the auxiliary motor 111 are started to make the support circular plate 104 and the pressing circular plate 106 return to the initial position. At this time, the lower surface of the support circular plate 104 falls off and contacts the lower surface of the plastic barrel. Under the action of the three squeezing rods 112, the plastic barrel will not move. Then the transposition motor 115 is started to drive the transmission gear 119 to rotate, so that the transposition gear 118 rotates. Under the action of the lifting screw rod 116 and the lifting gear 117, the two conveying bottom plates 102 are moved upward, and the spring between the conveying bottom plate 102 and the bottom plate 101 is compressed. One of the two conveying components is used to convey qualified plastic barrels, and the other conveying component is used to convey unqualified plastic barrels. At this time, under the action of the transposition motor 115, the transposition gear 118, and the transmission gear 119, the adjustment rotating frame 113 is rotated to the direction for conveying unqualified plastic barrels. Conveying assembly, at this time, the plastic barrel clamped by the three squeezing rods 112 is located above the conveyor belt in the conveying assembly, and at this time, the adjustment rotary frame 113 contacts the end face of the limiting strip 120, and the lower surface of the conveyor belt does not contact the lower surface of the plastic barrel, and the transposition gear 118 continues to rotate, and the torsion spring between the transposition gear 118 and the adjustment rotary frame 113 is compressed, so that the two conveying bottom plates 102 continue to move upward, and finally the conveyor belt contacts the lower surface of the plastic barrel, and then the squeezing motor 140 is started to make the adjustment push plate 125 return to the initial position, that is, the squeezing rod 112 releases the clamping of the plastic barrel, and the two fan-shaped strips 110 also return to the initial position, at this time, the conveying motor 114 corresponding to the conveyor belt is started, so that the conveyor belt can realize the conveying of unqualified plastic barrels, and then the transposition motor 115 is started, so that the conveying bottom plate 102, the adjustment rotary frame 113, and the transposition gear 118 all return to their initial positions.

[0050] If the air tightness of the plastic barrel is qualified after the test, the gas added to the sealed chamber formed between the plastic barrel and the pressing circular plate 106 will be discharged, and then the extrusion motor 140 will be started to drive the three extrusion rods 112 to fall off and contact the surface of the plastic barrel, and the auxiliary motor 111 will be started to drive the pressing circular plate 106 to continue to move downward, that is, a constant external force is applied to the plastic barrel from above the plastic barrel to test the strength of the plastic barrel. Under the action of multiple cameras arranged on the bottom plate 101, the deformation of the surface of the plastic barrel is monitored. If the plastic barrel is deformed under the constant external force, it is an unqualified product, and the above steps are repeated to place the plastic barrel on the conveyor belt in the conveying assembly for conveying unqualified products, and then the conveying motor 114 corresponding to the conveyor belt is started to realize the conveying of the unqualified plastic barrel.

[0051] After the pressing circular plate 106 applies a constant external force to the plastic barrel and the surface of the plastic barrel does not deform, the auxiliary motor 111 is started to make the pressing circular plate 106 fall off and contact the plastic barrel, and then the extrusion motor 140 is started to move the three extrusion rods 112 in the direction close to the axis of the supporting circular plate 104, that is, a constant external force is applied to the side of the plastic barrel through the adjustment rotating frame 113 to detect the strength of the plastic barrel. Under the action of multiple cameras arranged on the bottom plate 101, the deformation of the surface of the plastic barrel is monitored. If the plastic barrel is deformed under the constant external force, it is a defective product. Repeat the above steps, place the plastic barrel on the conveyor belt in the conveying assembly for conveying defective products, and then start the conveying motor 114 corresponding to the conveyor belt to realize the conveying of the defective plastic barrel.

[0052] If the above tests on the plastic barrels are all qualified, start the transposition motor 115 to drive the adjustment rotating frame 113 and the transposition gear 118 to rotate, and place the plastic barrel clamped by the extrusion rod 112 on the conveyor belt in the conveying assembly for conveying qualified products, and then start the conveying motor 114 corresponding to the conveyor belt to realize the conveying of qualified plastic barrels.

[0053] Repeat the above steps to detect the quality of the plastic barrel.

[0054] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
