It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all of them.

[0035] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0037] In the description of this embodiment, the terms "upper", "lower", "right", "left" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0039] This embodiment proposes a bottle washing machine, which includes a cleaning mechanism and a swing lifting mechanism. The cleaning mechanism is installed on the swing lifting mechanism. The cleaning mechanism is driven by the swing lifting mechanism to complete lifting and swinging to achieve the cleaning of the bottle body. The bottle washing machine is mainly used for cleaning bottles for food and medicine packaging. Of course, the bottle washing machine can also clean bottles for other products, which is not specifically limited here.

[0040] The lifting mechanism of the existing bottle washing machine is mostly a screw nut method, which realizes the lifting movement of the working spindle by assembling a motor to provide power. The above-mentioned screw nut method is not only complex in structure, but also inconvenient to disassemble and assemble. Moreover, the assembly conditions of the screw and the nut are relatively harsh, and the assembly error generated during assembly will reduce the lifting accuracy of the working spindle. In addition, the screw needs to maintain a fully lubricated working environment, so lubricating grease must be added regularly for protection, which makes it inconvenient to disassemble and maintain in the later stage.

[0041] To solve the above problems, Figure 1 and Figure 2 As shown, this embodiment also proposes a swing lifting mechanism, which includes a base 1, a lifting assembly 4 and a swing assembly 5. A mounting plate 2 is arranged above the base 1. The lifting assembly 4 includes a lifting drive 41, a seat frame 42 and a cam 43. The seat frame 42 is mounted on the base 1. The lifting drive 41 is connected to the cam 43 in a transmission manner to drive the cam 43 to rotate in the seat frame 42. The top end of the working spindle 3 movably passes through the mounting plate 2, and the bottom end of the working spindle 3 extends into the seat frame 42 and abuts against the cam 43, so that the working spindle 3 slides along the contour of the cam 43 and moves up and down relative to the mounting plate 2. The swing assembly 5 drives the working spindle 3 to rotate relative to the mounting plate 2 around the axial direction.

[0042] In this embodiment, the lifting drive member 41 drives the cam 43 to rotate, so that the working spindle 3 slides along the contour of the cam 43 and moves up and down relative to the mounting plate 2, and at the same time, the swing assembly 5 drives the working spindle 3 to rotate relative to the mounting plate 2, thereby realizing the swing lifting movement of the working spindle 3. When the cam 43 rotates, the working spindle 3 slides along the contour of the cam 43 to realize the lifting movement of the working spindle 3, thereby improving the precision of the lifting movement. At the same time, compared with the lifting method of the lead screw nut, the lifting assembly 4 of this embodiment realizes the lifting movement of the working spindle 3 through the cam 43, so that the lifting assembly 4 has a simple structure, does not need to lubricate the cam 43, and is convenient for disassembly and maintenance operations.

[0043] Specifically, Figure 1 and Figure 2As shown, the lifting assembly 4 also includes a rotating shaft 44 and a fixing plate 45, the fixing plate 45 is arranged on the base 1, one end of the rotating shaft 44 is rotatably mounted on the fixing plate 45, and the cam 43 is fixedly sleeved on the rotating shaft 44. The lifting drive member 41 is transmission-connected with the other end of the rotating shaft 44. The cam 43 is mounted on the rotating shaft 44 through a flat key to achieve circumferential limit of the cam 43 and ensure that the cam 43 and the rotating shaft 44 rotate synchronously. In addition, a locking ring is installed on the rotating shaft 44 to achieve axial limit of the cam 43, to prevent the cam 43 from axially moving on the rotating shaft 44, and to improve the stability of the assembly of the cam 43 and the rotating shaft 44.

[0044] The lifting drive member 41 of this embodiment includes a driving motor 411, a reducer 412 and a coupling 413. The reducer 412 is installed on the base 1. The output end of the driving motor 411 is connected to the coupling 413 through the reducer 412, and the other end of the rotating shaft 44 is connected to the coupling 413. The driving motor 411 has the advantages of small size, easy disassembly and assembly, and high control accuracy. By setting the reducer 412, the output torque of the driving motor 411 is increased, thereby improving the bearing capacity of the working spindle 3. The coupling 413 can stably transmit the output torque of the reducer 412 to the rotating shaft 44, and the coupling 413 can also play a role in buffering, vibration reduction and improving the dynamic performance of the shaft system.

[0045] like Figure 3 As shown, the lifting assembly 4 also includes a bearing seat 46 and a sliding rotary bearing 47. The bearing seat 46 is mounted on the seat frame 42. The working spindle 3 is mounted on the bearing seat 46 through the sliding rotary bearing 47 and extends into the seat frame 42. By arranging the sliding rotary bearing 47 in the bearing seat 46, the working spindle 3 can achieve smooth lifting and reciprocating movement in the bearing seat 46.

[0046] Specifically, Figure 2 and Figure 3 As shown, the working spindle 3 includes a shaft 31 and a follower plate 32, and the top end of the shaft 31 movably passes through the mounting plate 2. The bottom end of the working spindle 3 extends into the seat frame 42 and is provided with a follower plate 32, which is pressed against the top of the cam 43 and slides along the contour line of the cam 43. It should be noted that the contour line of the cam 43 includes an ascending contour line and a descending contour line. When the cam 43 rotates with the rotating shaft 44, the follower plate 32 slides along the ascending contour line or the descending contour line. When the follower plate 32 slides along the ascending contour line, the shaft 31 and the follower plate 32 rise, that is, the working spindle 3 moves from bottom to top relative to the mounting plate 2 (or the seat frame 42); when the follower plate 32 slides along the descending contour line, the shaft 31 and the follower plate 32 fall, that is, the working spindle 3 moves from top to bottom relative to the mounting plate 2 (or the seat frame 42).

[0047] Preferably, an elastic member 6 is installed between the follower plate 32 and the seat frame 42 in a compressed manner, and the elastic member 6 can make the follower plate 32 always have a tendency to move downward. Since the elastic member 6 is always in a compressed state, the follower plate 32 is always pressed against the contour line of the cam 43 under the action of the elastic restoring force, thereby achieving a close fit between the cam 43 and the follower plate 32, and improving the stability of the lifting process of the working spindle 3.

[0048] The elastic member 6 of this embodiment is a spring, which is sleeved on the shaft 31, and the two ends of the spring are respectively pressed against or connected to the follower plate 32 and the seat frame 42. The spring has the advantages of simple structure and easy installation. The spring is sleeved on the shaft 31, which improves the stability of the spring and prevents the spring from bending or dislocation. In other embodiments, the elastic member 6 can also be other elastic components such as elastic rubber.

[0049] It should be noted that if Figure 3 and Figure 4 As shown, two sleeves 8 are coaxially mounted on the mounting plate 2, one sleeve 8 is located on the upper surface of the mounting plate 2, and the other sleeve 8 is located on the lower surface of the mounting plate 2, and the working spindle 3 is slidably inserted into the two sleeves 8. The top end of the upper sleeve 8 and the butt joints of the two sleeves 8 are both equipped with sliding rotary bearings 47 to enable the working spindle 3 to move up and down and swing smoothly.

[0050] Now combined Figure 4 and Figure 5 The specific structure of the swing assembly 5 is described. Figure 4 and Figure 5 As shown, the swing assembly 5 includes a swing driving member 51, a gear 52, a swing arm 53 and a locking arm 54. The swing driving member 51 is connected to the gear 52 in a transmission manner. One end of the swing arm 53 is rotatably sleeved on the bearing seat 46, and the other end of the swing arm 53 is provided with a sector tooth 55 meshing with the gear 52. One end of the locking arm 54 is fixedly connected to the working spindle 3, and the other end of the locking arm 54 is movably connected to the swing arm 53, so that the swing arm 53 and the locking arm 54 rotate synchronously. Specifically, one end of the swing arm 53 is rotatably sleeved on the outer periphery of the bearing seat 46 through two rotating bearings 7, so that the swing arm 53 can rotate around the axial direction of the working spindle 3.

[0051] The swing drive member 51 of this embodiment is a servo motor, which is small in size and easy to disassemble and assemble, and has high control accuracy, further improving the swing accuracy of the working spindle 3. In other embodiments, the swing drive member 51 can also be other conventional drive components, which are not specifically limited here.

[0052] When the lifting assembly 4 drives the working spindle 3 to move up and down, since one end of the locking arm 54 is fixedly connected to the working spindle 3, and the other end of the locking arm 54 is liftably connected to the swing arm 53, the locking arm 54 can be lifted and lowered synchronously with the working spindle 3 relative to the swing arm 53. The gear 52 in the swing assembly 5 is meshed with the sector teeth 55 on the swing arm 53, so that the locking arm 54 can rotate with the swing arm 53 and can also drive the working spindle 3 to rotate synchronously, thereby realizing the lifting and swinging of the working spindle 3 (that is, the working spindle 3 moves along the swing arm 53). Figure 4 The gear 52 and the sector tooth 55 are meshed stably and reliably, which improves the precision and stability of the swinging process of the working spindle 3. At the same time, the gear 52 and the sector tooth 55 are not only easy to manufacture, but also require lower assembly precision, and occupy less space, simplify the structure, and realize the compact installation of the swing lifting mechanism.

[0053] like Figure 5 As shown, one end of the locking arm 54 has a hoop structure 543, and the locking arm 54 holds the working spindle 3 through the hoop structure 543. The locking arm 54 is fixedly connected to the working spindle 3 through the hoop structure 543, which improves the connection stability between the locking arm 54 and the working spindle 3. When the locking arm 54 rotates with the swing arm 53, the working spindle 3 rotates synchronously on the bearing seat 46, so that the working spindle 3 can perform lifting and rotating movements in the bearing seat 46 respectively.

[0054] Specifically, the swing assembly 5 further includes a connecting plate 56, one end of which is fixedly connected to the swing arm 53, and the connecting plate 56 is slidably clamped to an end of the locking arm 54 away from the working spindle 3 in the vertical direction (the up-down direction in the figure). The swing arm 53 and the locking arm 54 are arranged in parallel and movably connected through the connecting plate 56. The swing arm 53 drives the locking arm 54 and the working spindle 3 to rotate through the connecting plate 56, and when the working spindle 3 moves up and down, the locking arm 54 slides on the connecting plate 56 in the vertical direction.

[0055] Specifically, the locking arm 54 includes a first arm plate 541 and two wheel bodies 542, and one end of the first arm plate 541 is connected to the working spindle 3. The two wheel bodies 542 are spaced and rotatably arranged at the other end of the first arm plate 541, and the connecting plate 56 is slidably clamped between the two wheel bodies 542 in the vertical direction. When the locking arm 54 moves along the vertical direction with the working spindle 3, the two wheel bodies 542 slide in the vertical direction on the opposite sides of the connecting plate 56. The locking arm 54 makes rolling friction between the wheel body 542 and the connecting plate 56 through the sliding cooperation between the wheel body 542 and the connecting plate 56, which greatly reduces the friction resistance between the locking arm 54 and the connecting plate 56, not only reduces the output power of the lifting drive member 41, but also can avoid the wheel body 542 and the connecting plate 56 from being worn out, thereby improving the protection of the connecting plate 56. The wheel body 542 of this embodiment can be a rolling body such as a roller or a bearing, and it only needs to be able to roll with the connecting plate 56.

[0056] Furthermore, if Figure 5 As shown, the swing assembly 5 also includes a reinforcing arm 57 located above the locking arm 54, one end of the reinforcing arm 57 is rotatably disposed on the mounting plate 2, and the other end of the reinforcing arm 57 is connected to an end of the connecting plate 56 away from the swing arm 53. The swing arm 53, the locking arm 54 and the reinforcing arm 57 are arranged in sequence from bottom to top in the vertical direction, so that the upper and lower ends of the connecting plate 56 are respectively connected to the reinforcing arm 57 and the swing arm 53, so as to prevent the connecting plate 56 from being twisted and deformed, thereby improving the structural strength and stability of the swing assembly 5. At the same time, the swing arm 53 and the reinforcing arm 57 can limit the lifting and lowering movement of the locking arm 54 in the vertical direction.

[0057] like Figure 4 and Figure 5 As shown, the swing assembly 5 also includes a pull rod assembly 58 and a tension spring 59. One end of the pull rod assembly 58 is fixedly connected to the locking arm 54, and the other end of the pull rod assembly 58 movably passes through the swing arm 53. One end of the tension spring 59 is connected to the reinforcing arm 57, and the other end of the tension spring 59 is connected to the other end of the pull rod assembly 58. When the locking arm 54 rises along the vertical direction with the working spindle 3, the pull rod assembly 58 rises synchronously with the locking arm 54, and the tension spring 59 is compressed; when the locking arm 54 falls along the vertical direction with the working spindle 3, the pull rod assembly 58 falls synchronously with the locking arm 54, and the tension spring 59 is stretched. By setting the tension spring 59, a good buffering effect can be played on the lifting and lowering movement of the working spindle 3, thereby improving the stability of the lifting and lowering movement process of the working spindle 3.

[0058] Specifically, the pull rod assembly 58 includes a vertical rod 581 and a horizontal rod 582. The vertical rod 581 extends in the vertical direction and one end of the vertical rod 581 is connected to the locking arm 54. The other end of the vertical rod 581 passes through the swing arm 53 and extends toward the base 1. The other end of the vertical rod 581 is provided with a horizontal rod 582, and the vertical rod 581 and the horizontal rod 582 are connected in a T shape. There are two tension springs 59, and both ends of the horizontal rod 582 are fixedly hung with a tension spring 59, which further enhances the buffering effect.

[0059] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
