DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figures 1 to 8 As shown, a connecting rod shaft supporting device for a large infusion bottle washing and filling machine according to an embodiment of the present invention comprises: a workbench 1; a filling mechanism 3 and a capping mechanism 4 fixedly connected to the top of the workbench 1; a receiving box 11 fixedly connected to the top of the workbench 1, the filling mechanism 3 and the capping mechanism 4 respectively cooperate with the receiving box 11; a rotating block 12 arranged inside the receiving box 11; a connecting rod 134 fixedly connected to the bottom of the rotating block 12; a supporting mechanism arranged at the bottom of the connecting rod 134; the supporting mechanism comprises a fixing block 136 connected to the bottom of the workbench 1 by four fastening bolts 138, the connecting rod 134 passes through the bottom of the receiving box 11 and is rotatably connected to the workbench 1 by a bearing. On the table 1, the bottom end of the connecting rod 134 extends to the bottom of the workbench 1 and is fixedly connected to the second gear 133. The bottom of the workbench 1 is fixedly connected to an L-shaped plate 13, and the top of the L-shaped plate 13 is fixedly connected to a second motor 131. The output shaft of the second motor 131 is rotatably connected to the bottom of the workbench 1 through a bearing, and the output shaft of the second motor 131 is fixedly connected to a first gear 132, and the first gear 132 is meshed with the second gear 133; the top of the fixed block 136 is rotatably connected to a cross block 137 through a rotating shaft, and a limiting groove 135 is provided at the bottom of the connecting rod 134, and the cross block 137 is inserted in the limiting groove 135.

[0038] In order to solve the problem of unstable operation caused by uneven force on the connecting rod 134, when the supporting mechanism provided by the present invention is used, the handheld fixing block 136 is inserted into the limiting groove 135 by aligning the cross block 137, and then the fixing block 136 is fixed on the workbench 1 by the fastening bolt 138. When working, by turning on the second motor 131, the second motor 131 drives the first gear 132 to rotate through the output shaft, drives the second gear 133 to rotate through the first gear 132, drives the connecting rod 134 to rotate through the second gear 133, and drives the rotating blocks 12 and the cross block 137 at both ends to rotate respectively through the connecting rod 134, and limits the connecting rod 134 to one side of the fixing block 136 through the cross block 137, and achieves the balance of the connection force of the first gear 132 and the second gear 133 by increasing the force point of the connecting rod 134, so as to stably drive the operation of other connecting components, thereby ensuring the stable operation of the equipment, reducing the production cost, reducing the material waste, and improving the product qualification rate.

[0039] like Figure 5 , Figure 7 and Figure 8As shown, placement openings 126 are arranged in a circle on the edge of the rotating block 12, and clamping blocks 122 are provided in the placement openings 126. The clamping blocks 122 are slidably connected in the rotating block 12; the tops of the clamping blocks 122 are fixedly connected to limiting columns 124; a first motor 123 is provided in the rotating block 12, and the output shaft of the first motor 123 is fixedly connected to a circular plate 121, and the limiting columns 124 slide on the circular plate 121.

[0040] The clamping block 122 provided by the present invention is used for clamping the filling bottle when in use. The filling bottle is placed in the placement opening 126, and the first motor 123 is turned on. The circular plate 121 is driven to rotate by the output shaft of the first motor 123. When the circular plate 121 rotates, it squeezes the limiting column 124 through the arc opening 125, thereby driving the limiting column 124 to rotate. When the limiting column 124 rotates, it is also restricted by the rotating block 12 and slides along the rectangular opening 127. During the movement, the limiting column 124 drives the clamping block 122 to move. The clamping block 122 slides in the rotating block 12 until the filling bottle is clamped and just contacts the inner wall of the receiving box 11, and then stops, thereby realizing the function of fixing filling bottles of different diameters.

[0041] like Figure 7 and Figure 8 As shown, the circular plate 121 is provided with a plurality of arc-shaped openings 125 , and the limiting posts 124 all slide in the arc-shaped openings 125 . The rotating block 12 is provided with a plurality of rectangular openings 127 , and the limiting posts 124 all slide in the rectangular openings 127 .

[0042] The arc-shaped opening 125 and the rectangular opening 127 provided by the present invention are used to limit the limiting column 124 when in use. By setting the arc-shaped opening 125, when the circular plate 121 rotates, the circular plate 121 squeezes the limiting column 124 through the arc-shaped opening 125, and the limiting column 124 rotates along the arc-shaped opening 125, but at the same time, the bottom of the limiting column 124 is restricted by the rectangular opening 127 and slides along the rectangular opening 127, so that the limiting column 124 diverges or contracts at the same time, thereby clamping filling bottles with different diameters.

[0043] like Figure 5 and Figure 6 As shown, an oil storage box 14 is fixedly connected to the inner wall of the bottom of the receiving box 11, and the oil storage box 14 is sleeved on the outside of the connecting rod 134. A conical block 141 is sleeved on the outside of the connecting rod 134. A spring 142 is provided between the conical block 141 and the receiving box 11, and an oil seal 146 is installed between the bottom of the workbench 1 and the connecting rod 134.

[0044] The conical block 141 provided by the present invention is used to seal the oil storage box 14 when in use. Lubricating oil is input into the oil storage box 14 to lubricate transmission parts such as bearings and sleeves. The sealing and unblocking of the oil storage box 14 is achieved by lifting and lowering the conical block 141. The oil seal 146 is provided to prevent the lubricating oil from overflowing.

[0045] like Figure 6 As shown, two rectangular plates 143 are fixedly connected to both ends of the top inner wall of the receiving box 11, and a cam block 145 is rotatably connected between the two rectangular plates 143 through a rotating shaft, wherein a third motor 144 is fixedly connected to the outer walls of two adjacent rectangular plates 143, and the output shaft of the third motor 144 is fixedly connected to one end of the rotating shaft; the third motor 144 is a forward and reverse motor.

[0046] When the cam block 145 provided by the present invention is in use, the third motor 144 adopts a forward and reverse motor and can be turned on at a fixed time. After the two third motors 144 are turned on, the output shaft drives the rotating shaft and the cam block 145 to rotate, and the cam block 145 rotates upward to release the fixation of the conical block 141. Under the action of the spring 142, the conical block 141 bounces upward, and the lubricating oil in the oil storage box 14 flows out; then the third motor 144 rotates in the opposite direction, and the output shaft drives the rotating shaft and the cam block 145 to rotate, and the cam block 145 rotates downward to press the conical block 141 tightly into the receiving box 11, thereby realizing the sealing of the lubricating oil in the oil storage box 14 and reducing the waste of lubricating oil.

[0047] like Figure 5 As shown, the receiving box 11 is connected and fixed with a drainage pipe 112, one end of the drainage pipe 112 is connected and fixed with the oil storage box 14, and the other end of the drainage pipe 112 is inserted with a plug 113, and the drainage pipe 112 is arranged obliquely.

[0048] When the drainage tube 112 provided by the present invention is in use, the drainage tube 112 is provided to facilitate the input of lubricating oil into the oil storage box 14, and then the plug 113 is inserted into one end of the drainage tube 112 for dust prevention and sealing.

[0049] like Figure 1 As shown, conveyor belts 2 are respectively provided on both sides of the workbench 1, and two through openings 111 are opened on the receiving box 11. The through openings 111 are respectively matched with the two conveyor belts 2, and the two conveyor belts 2 are not on the same side as the filling mechanism 3 and the capping mechanism 4.

[0050] When the through opening 111 provided by the present invention is in use, the two conveyor belts 2 are respectively used for loading and unloading. The conveyor belt 2 close to the filling mechanism 3 is recorded as the loading conveyor belt 2, and the conveyor belt 2 close to the capping mechanism 4 is recorded as the unloading conveyor belt 2. The filled bottles after cleaning and air blowing are placed on the loading conveyor belt 2, enter the receiving box 11 through the through opening 111, and are driven by the rotating block 12 to be filled and capped in turn. After capping, they are output from the receiving box 11 through the next through opening 111 and output via the unloading conveyor belt 2.

[0051] like Figure 8 As shown, anti-skid pads are fixedly connected to the inner walls of the clamping block 122, and the anti-skid pads are made of rubber material.

[0052] When the clamping block 122 provided by the present invention is in use, anti-skid pads are fixedly connected to the inner walls of the clamping block 122 to prevent the filling bottle from sliding and deflecting, making it impossible to align the filling and capping. The rubber material prevents excessive clamping force from damaging the filling bottle.

[0053] Working principle: During operation, the filled bottles after cleaning and air blowing are placed on the feeding conveyor belt 2, and enter the receiving box 11 through the opening 111. Under the action of the rotating block 12, the filled bottles are driven to be filled and capped in turn. After capping, they are output from the receiving box 11 through the next opening 111 and output through the discharging conveyor belt 2. In order to solve the problem of unstable operation caused by uneven force on the connecting rod 134, the handheld fixed block 136 is inserted into the limit groove 135 by aligning the cross block 137, and then the fixed block 136 is fixed to the workbench 1 by the fastening bolts 138. During operation, by turning on the second motor 131, the second motor 1 The output shaft 31 drives the first gear 132 to rotate, the first gear 132 drives the second gear 133 to rotate, the second gear 133 drives the connecting rod 134 to rotate, the connecting rod 134 drives the rotating block 12 and the cross block 137 at both ends to rotate respectively, and the connecting rod 134 is limited to one side of the fixed block 136 by the cross block 137. By increasing the force point of the connecting rod 134, the connection force of the first gear 132 and the second gear 133 is balanced, and the operation of other connecting components is driven stably, which ensures the stability of equipment operation, reduces production costs, reduces material waste, and improves product qualification rate;

[0054] By turning on the first motor 123, the circular plate 121 is driven to rotate through the output shaft of the first motor 123. When the circular plate 121 rotates, it squeezes the limiting column 124 through the arc-shaped opening 125. The limiting column 124 rotates along the arc-shaped opening 125. When the limiting column 124 rotates, it is limited by the rotating block 12 and slides along the rectangular opening 127. During the movement, the limiting column 124 drives the clamping block 122 to move. The clamping block 122 slides in the rotating block 12 until the filling bottle is clamped and just contacts the inner wall of the receiving box 11, and then stops, thereby realizing the function of fixing filling bottles with different diameters.

[0055] After the third motor 144 is turned on, the rotating shaft and the cam block 145 are driven to rotate through the output shaft, and the cam block 145 is rotated upward to release the fixation of the conical block 141. Under the action of the spring 142, the conical block 141 bounces upward, and the lubricating oil in the oil storage box 14 flows out; then the third motor 144 rotates in the opposite direction, and the rotating shaft and the cam block 145 are driven to rotate through the output shaft, and the cam block 145 is rotated downward to press the conical block 141 tightly into the receiving box 11, thereby achieving sealing of the lubricating oil in the oil storage box 14 and reducing the waste of lubricating oil.
