Abstract
Description
Technical Field
[0001] The utility model relates to a filling machine, in particular to a cam ring regulating mechanism in a rotary filling machine. Background Art
[0002] In the rotary filling machine, a plurality of filling heads are evenly distributed on the circumference above the frame, a cam ring is arranged in the frame, a turntable is coaxially arranged in the cam ring, and snap-ons capable of clamping bottles are evenly distributed on the turntable. A cross bar is provided between the uprights on the left and right sides of the frame for sliding, and a lifting mechanism capable of adjusting the lifting of the cross bar is provided on the left and right sides of the frame respectively. The left and right ends of the cam ring are respectively hinged to the cross bars on the left and right sides. When the left and right ends of the cam ring are in an up-and-down tilted state, the left and right ends of the turntable are also in an up-and-down tilted state. During the rotation, the bottle at the lowest position on the left will rotate to the highest position on the right. During this process, the bottle will first rest against the filling head and be coaxially sealed with the filling head. As the bottle rotates upward, the bottle presses the filling head upward, and the filling valve in the filling head will open after receiving the top pressure, and the filling head will fill the bottle. In this process, the filling head rotates synchronously with the turntable. When the bottle on the turntable rotates away from the highest position, the filling valve will gradually close. After the filling is completed, the bottle will be received by the receiving mechanism in the capping mechanism for capping during the rotation.
[0003] When it is necessary to fill bottles of different heights, it is necessary to adjust the cross bar through the lifting mechanism to adjust the position height of the corresponding end of the cam ring. However, during adjustment, the lifting mechanism can only apply an upward force to the cross bar on the same side, and the balance of the cross bar cannot be guaranteed after the cross bar is connected to the cam ring. When the cross bar is lifted, it is easy to lift it in a forward and backward tilted state, which makes it easy for the cross bar and the column to get stuck. Not only is it inconvenient to lift, but it is also easy to make the cam ring and the turntable tilt forward and backward, which will cause the bottle on the turntable and the filling head against each other to have an angle and cannot be completely sealed, resulting in leakage during filling.

[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.
[0018] like Figure 1 to Figure 5As shown, the cam ring adjustment mechanism in the rotary filling machine described in the utility model comprises: a frame 1, a cam ring 2 is movably arranged in the frame 1, two columns 11 are arranged on the frame 1 on the left and right sides of the cam ring 2, an upper cross bar 12 is horizontally arranged between the two columns 11 on the same side, the left and right upper cross bars 12 are arranged in high and low positions, two copper sleeves 121 are symmetrically arranged in the front and rear of the upper cross bar 12, a stainless steel segmented shaft 3 is rotatably passed through the copper sleeve 121, the smooth section of the segmented shaft 3 is located in the copper sleeve 121, a boss is arranged on the smooth section of the segmented shaft 3, the boss abuts against the copper sleeve 121, a sprocket 31 is arranged on the smooth section, a chain 32 is arranged between the sprockets 31 of the two segmented shafts 3, and a chain 32 is arranged on the left and right sides. A handwheel 33 is provided on any one of the segmented shafts 3, and the handwheel 33 is connected to the segmented shaft 3 through a hand-cranked right-angle reducer 34, and the hand-cranked right-angle reducer 34 is fixed on the frame 1, and the handwheel 33 is key-connected with the input shaft on the hand-cranked right-angle reducer 34, and the hollow output pipe on the hand-cranked right-angle reducer 34 is coaxially arranged with the segmented shaft 3, and the smooth section of the segmented shaft 3 extends into the hollow output pipe and is key-connected, and the threaded section of the segmented shaft 3 passes downward through the upper cross block 12, and the two segmented shafts 3 on the same side are connected with a lower cross block 4 that is not in direct contact with the two columns 11 on the same side, and two copper nuts 41 are symmetrically arranged at the front and rear ends of the lower cross block 4, and the threaded section on the segmented shaft is threadedly connected to the corresponding copper nuts 41 on the same side, and the two on the upper cross block 12 The segmented shaft 3 is threadedly connected at the front and rear symmetrical positions of the lower cross bar 4, which can exert a balanced pulling force on the lower cross bar 4, ensuring that the lower cross bar 4 can be stably lifted and lowered under the threaded transmission of the two segmented shafts 3. When the segmented shaft 3 made of stainless steel is threadedly matched with the copper nut 41, the copper nut 41 with a softer material can reduce the wear between the threads and reduce the jamming phenomenon. Moreover, when an overload occurs, the copper nut 41 can fail before the segmented shaft 3, which plays a certain protective role for the segmented shaft 3. An inner clamping plate 42 is slidably provided at the front and rear ends of the lower cross bar 4, and a slide plate 421 is vertically provided on the inner clamping plate 42. A long hole 422 is opened on the slide plate 421, and the slide plate 421 is slidably provided on the lower cross bar 4. 2 is penetrated by a second bolt 423, and the second bolt 423 is threadedly connected with the lower cross block 4 after passing through the long hole 422. A plurality of threaded through holes are arranged on each inner clamping plate 42, and an outer clamping plate 43 is arranged on the outer side of the inner clamping plate 42. A plurality of through holes are arranged on the outer clamping plate 43, and the through holes on the outer clamping plate 43 are aligned one by one with the threaded through holes on the inner clamping plate 42. A first bolt 431 is penetrated in the through hole, and the first bolt 431 is threadedly connected with the aligned threaded through holes. The column 11 is located between the inner clamping plate 42 and the outer clamping plate 43 on the same side. The left and right ends of the cam ring 2 are respectively hinged to the lower cross block 4 on the same side. The connection structure between the cam ring 2 and the lower cross block 4 is as follows: two straight plates 44 with hinged holes are symmetrically arranged at the front and rear ends of the lower cross block 4.Two U-shaped plates 21 with long hinge holes are symmetrically arranged on the left and right semicircular rings of the cam ring 2. The two straight plates on the lower cross bar 4 extend into the two U-shaped plates on the corresponding sides respectively. The hinge holes on the straight plates 44 are aligned with the long hinge holes on the corresponding U-shaped plates 21. The pins 22 are inserted into the aligned hinge holes.
[0019] The left and right upper crosspieces 12 are arranged at different heights, and then the segmented shafts 3 of equal length are arranged on the upper crosspiece 12, and then the two copper nuts 41 on the lower crosspiece 4 are respectively pressed against the threaded sections of the two segmented shafts 3 on the same side, and then the hand wheel 33 is turned and the number of turns of the hand wheel 33 is remembered. The hand wheel 33 drives the corresponding segmented shaft 3 to rotate through the hand-cranked right-angle reducer 34, and since the two segmented shafts 3 on the same side are connected to each other through the chain transmission structure of the sprocket 31 and the chain 32, the two segmented shafts on the same side are connected to each other through the chain transmission structure of the sprocket 31 and the chain 32. The shaft 3 will rotate synchronously, in the same direction and at the same speed. The threaded sections on the two segmented shafts 3 can control the parallel rise of the lower cross block 4 to the X stroke after matching with the corresponding copper nuts 41. When the lower cross block 4 on one side is installed, the lower cross block 4 on the other side is installed. When installing the lower cross block 4 on the other side, it is necessary to rotate the hand wheel 33 the same number of times so that the lower cross block 4 on the other side can also be parallel to the X stroke of the two segmented shafts 3 on that side. At this time, the two lower cross blocks 4 are also set at a high and low level, and then the outer clamping plate 43 is screwed on. The first bolt 431 is screwed, and when the first bolt 431 is screwed, the inner clamping plate 42 moves toward the column 11 under the thread transmission force of the first bolt 431 and the inner clamping plate 42, and the outer clamping plate 43 also moves toward the column 11 under the pushing action of the first bolt 431. When the inner clamping plate 42 and the outer clamping plate 43 are both against the column 11, the inner clamping plate 42 and the outer clamping plate 43 are locked on the column 11, so that the lower cross bar 4 is locked on the two columns 11 of the frame 1, and then the cam ring 2 is hinged at the two When the cam ring 2 is in this inclined state, the bottles on the turntable installed on the cam ring 2 can be in coaxial sealing contact with the circumferentially uniformly distributed filling heads during the process of rotating from a low position to a high position. In this way, the inclination of the cam ring 2 and the turntable during installation is controlled by the height difference between the two upper cross bars 12 designed in advance. No additional adjustment work is required during the installation process, and it can be achieved by rotating the hand wheels 33 on both sides the same number of times.
[0020] Before filling bottles of different sizes, it is only necessary to adjust the height of the cam ring 2 according to the height of the bottles: first, loosen the first bolt 431 between the outer clamping plate 43 and the inner clamping plate 42 in reverse, so that the outer clamping plate 43 and the inner clamping plate 42 are no longer locked on the column 11, and the lower cross block 4 is disengaged from the two columns 11 on the same side, and then rotate the hand wheel 33 on one side by Y circles, and the hand wheel 33 drives the two segmented shafts 3 on the same side to rotate, and the horizontal lifting height H of the side end of the cam ring 2 is controlled by controlling the lifting height of the lower cross block 4, and then rotate the hand wheel 33 on the other side by Y circles, and the side end of the cam ring 2 on the same side of the hand wheel 33 is also horizontally lifted by the same height H. In this way, the cam ring 42 and the turntable can be lifted and lowered at the same inclination by controlling the number of rotations of the two hand wheels 33, which is convenient for adjustment.
