[0074] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0075] like Figure 1 and Figure 2 , which are schematic diagrams of the structures of some embodiments of the bottle washing device according to the present disclosure at front and side angles. Figure 1 and Figure 2 In some embodiments, the bottle washing equipment includes a frame 1, a rotating mechanism, a bottle pressing mechanism 3 and a cleaning mechanism 4. The frame 1 can be fixedly or movably set on the ground or platform of the working area. The rotating mechanism is arranged on the frame 1, and is used to carry the bottle 9 to be washed and drive the bottle 9 to rotate. The bottle pressing mechanism 3 is arranged on the frame 1 and has a bottle pressing head 35, which is used to press the bottle mouth of the bottle 9 through the bottle pressing head 35. The bottle pressing head 35 may include a silicone material to achieve an elastic pressing and sealing effect on the bottle mouth. The cleaning mechanism 4 is arranged on the frame 1, and is used to clean the outer wall of the bottle 9 when the rotating mechanism drives the bottle 9 to rotate.

[0076] In this embodiment, the bottle mouth of the bottle is pressed by the bottle pressing head of the bottle pressing mechanism, and the bottle is driven to rotate in the pressed state by the rotating mechanism, and the outer wall of the bottle is cleaned by the cleaning mechanism, so that the outer wall of the bottle with contents can be cleaned.

[0077] refer to Figure 3, for the related art involving the washing of bottles of different specifications, in some embodiments, the bottle pressing head 35 in the bottle pressing mechanism 3 has a truncated cone-shaped end. When the bottle pressing mechanism presses the bottle pressing head toward the bottle mouth of the bottle 9, the smaller diameter part of the truncated cone-shaped end can enter the bottle mouth, while the larger diameter part cannot enter the bottle mouth, thereby pressing the bottle mouth of the bottle 9 through a certain part of the conical surface of the truncated cone-shaped end. For bottles with different bottle mouth sizes, the truncated cone-shaped end of the bottle pressing head 35 ensures the pressing effect on the bottle mouth through different entry depths. In order to achieve the effect of matching bottles of various specifications, and considering avoiding the bottle pressing head 35 from entering the bottle too deeply and interfering with the contents in the bottle, the truncated cone height h of the truncated cone end is preferably 10 to 50 mm, and more preferably 15 to 50 mm; the angle α between the truncated cone generatrix of the truncated cone end and the bottom surface is 30 to 60 degrees.

[0078] By setting the truncated cone height and angle parameters of the truncated cone end of the bottle pressing head, it can be adapted to bottles of various specifications with different bottle mouth sizes, so that bottles of different bottle mouth sizes can be cleaned on the outside with the bottle mouth sealed without replacing the cleaning mold, thereby simplifying the cleaning of bottles of different specifications and improving the bottle washing efficiency.

[0079] refer to Figure 3 In some embodiments, the bottle pressing mechanism 3 further includes: a bottle pressing bearing seat 37a, a bottle pressing shaft 36 and a bottle pressing bearing 37b. The bottle pressing bearing seat 37a has a first hollow structure. The bottle pressing shaft 36 is partially located in the first hollow structure, and one end of the bottle pressing shaft 36 is provided with the bottle pressing head 35. The bottle pressing bearing 37b is located between the first hollow structure and the bottle pressing shaft 36, and the outer ring of the bottle pressing bearing 37b is fixedly connected to the inner wall of the bottle pressing bearing seat 37a to form a radial support for the bottle pressing shaft 36. The bottle pressing shaft 36 can rotate relative to the bottle pressing bearing seat 37a as the bottle pressing head 35 rotates.

[0080] By arranging the bottle pressing bearing between the bottle pressing shaft and the first hollow structure of the bottle pressing bearing seat, the bottle pressing shaft can rotate relative to the bottle pressing bearing seat as the bottle pressing head rotates. Compared with the method of arranging the bottle pressing bearing between the bottle pressing head and the bottle pressing shaft and fixing it with a retaining spring, the bottle pressing bearing of this embodiment is not easy to be dislocated or fall off when the bottle pressing head rotates, thereby making the operation of the bottle pressing mechanism more reliable.

[0081] exist Figure 3In the embodiment, the bottle pressing mechanism 3 may include at least two bottle pressing bearings 37b arranged in the axial direction. The bottle pressing mechanism 3 also includes: a bearing inner sleeve 37d, a spring 38 and a fixing member 39.

A shaft sleeve 37c for defining the position of each bottle pressing bearing 37b may be arranged between adjacent bottle pressing bearings 37b, and the shaft sleeve 37c is sleeved on the outside of the bearing inner sleeve 37d. A retaining ring may also be arranged on at least one side of the axial direction of at least two bottle pressing bearings 37b to assist in fixing the bottle pressing bearing 37b in the bearing fixing seat 37a.

The fixing member 39 is fixedly connected to one end of the bottle pressing shaft 36 that passes through the bearing inner sleeve 37d and is away from the bottle pressing head 35, and is located on the side of the bearing inner sleeve 37d away from the spring 38, and is used to axially limit the bottle pressing shaft 36. The fixing member 39 can be a locking nut, and the radial dimension of the fixing member 39 is larger than the inner diameter of the bearing inner sleeve 37d, so as to constrain the bottle pressing shaft 36 on the side of the bearing inner sleeve 37d away from the bottle pressing head 35.

[0083] In order to more reliably install the pressure bottle bearing and spring, refer to Figure 3 In some embodiments, a radial flange is provided at one end of the bearing inner sleeve 37d adjacent to the fixing member 39, which is used to axially limit one of the at least two bottle pressing bearings 37b adjacent to the fixing member 39. The radial dimension of the radial flange is larger than the other parts of the bearing inner sleeve 37d, and the bottle pressing bearing 37b sleeved on the bearing inner sleeve 37d can be axially limited. An inner step is provided at one end of the bearing inner sleeve 37d adjacent to the bottle pressing head, and the inner step and the bottle pressing shaft 36 can form an annular space for accommodating one end of the spring 38, so that the installation of the spring 38 is more stable and the interference between the spring 38 and the bottle pressing bearing 37b can be avoided.

[0084] refer to Figure 1 and Figure 2In some embodiments, the bottle pressing mechanism 3 further includes: a bottle pressing support seat 31, a bottle pressing rack 34 and a bottle pressing driving mechanism 32.

The bottle pressing driving mechanism 32 is connected to the bottle pressing rack 34, and is used to drive the bottle pressing rack 34 to move relative to the bottle pressing support seat 31. The bottle pressing driving mechanism 32 can be implemented by a cylinder or a linear motor. A guide bearing 33 can also be arranged between the bottle pressing rack 34 and the bottle pressing support seat 31 to guide the stable translational movement of the bottle pressing rack 34. In some embodiments, the bottle pressing driving mechanism 32 includes a bottle pressing cylinder. The bottle pressing cylinder enables the bottle pressing head to elastically press the bottle mouth to match bottles with bottle mouths of different diameters.

[0085] exist Figure 1 In the embodiment, the bottle pressing shaft 36 is rotatably arranged on the bottle pressing rack 34, and can move with the bottle pressing rack 34 toward the rotating mechanism, and press the bottle mouth of the bottle 9 at least from the inner side of the bottle mouth through the truncated cone end of the bottle pressing head 35, and move with the bottle pressing rack 34 away from the rotating mechanism, so that the truncated cone end of the bottle pressing head 35 is separated from the bottle mouth of the bottle 9. The bottle pressing mechanism 3 may include a plurality of bottle pressing shafts 36 and bottle pressing heads 35, and each of the bottle pressing shafts 36 is arranged on the bottle pressing rack 34, so that the bottle pressing driving mechanism 32 can drive the plurality of bottle pressing shafts 36 to move synchronously by driving the bottle pressing rack 34 to move, so as to realize the operation of synchronously pressing the bottle mouth or synchronously separating from the bottle mouth of each bottle pressing head 35.

The bottle clamping and conveying mechanism 5 is arranged on the frame 1, and has a pair of bottle clamping belts 51 that can move toward each other as a whole and move along the conveying direction, and is used to clamp a plurality of bottles 9 to be washed input into the bottle washing device through the overall movement toward each other of the pair of bottle clamping belts 51, and convey the bottles 9 to be washed to the rotating mechanism in a straight line through the rotation of the pair of bottle clamping belts 51, and convey the washed bottles 9 from the rotating mechanism to the outside of the bottle washing device in a straight line.

[0087] The present embodiment provides a bottle clamping and conveying mechanism, which can clamp a plurality of bottles to be cleaned and translate them in a straight line. Compared with the related art in which the method of inputting and outputting bottles through a disc is limited to the use of bottle clamping molds of specific specifications, the present embodiment can match the movement of bottles of different specifications with different external dimensions in and out of the device by adjusting the spacing between the paired bottle clamping belts 51, without having to replace the bottle clamping molds or bottle washing equipment of corresponding specifications according to the bottles, thereby simplifying the cleaning of bottles of different specifications and improving the bottle washing efficiency.

[0088] exist Figure 1 and Figure 2 In the embodiment, the bottle clamping conveying mechanism 5 further comprises: a pair of bottle clamping support seats 54, a first power mechanism 53, a driving pulley and a driven pulley.

In this way, the bottle clamping belt 51 can achieve the displacement movement of multiple bottles within its conveyable range. The surfaces of the two bottle clamping belts 51 for clamping bottles are substantially parallel and parallel to the arrangement direction of each bottle. In order to increase the friction between the bottle clamping belt 51 and the bottle 9, it is preferred that the surface of the bottle clamping belt 51 is provided with a regular or irregular concave-convex pattern, such as a concave-convex pattern.

[0090] exist Figure 2 In the embodiment, the bottle clamping conveying mechanism 5 may further include: a second power mechanism 52 and a guide bearing 55.

The axes of the plurality of driven wheels 74 are all located in the first plane S1, the axes of the plurality of tensioning wheels 75 are all located in the second plane S2 parallel to the first plane S1, and are staggered with the plurality of driven wheels 74 in a direction parallel to the second plane S2 and perpendicular to the axis direction of the tensioning wheels 75, and a portion of the synchronous belt 73 is located between the first plane S1 and the second plane S2. In order to adjust the tension of the synchronous belt 73, in some embodiments, the spacing between the second plane S2 and the first plane S1 is adjustable.

[0099] refer to Figure 6 In some embodiments, the cleaning mechanism 4 includes: a cleaning support seat 42 and a cleaning drive mechanism 41. The cleaning support seat 42 is arranged on the frame 1, and the cleaning drive mechanism 41 is drivingly connected to the cleaning support seat 42, and is used to drive the cleaning support seat 42 to move as a whole relative to the frame 1. A brush 43, a spray head 44 and / or an air jet 45 can be arranged on the cleaning support seat 42. For simultaneous cleaning of multiple bottles, multiple groups of brushes 43, spray heads 44 and / or air jets 45 can be arranged on one or a pair of cleaning support seats 42, so that the brushes 43, spray heads 44 and / or air jets 45 for cleaning multiple bottles can be synchronously driven.

[0100] After the bottle pressing head 35 presses the bottle mouth, the brush 43 can approach the bottle mouth as the cleaning support seat 42 moves, and when the bottle 9 rotates, the outer wall of the bottle 9 can be scrubbed with the bristles. After the bottle pressing head 35 presses the bottle mouth, the spray head 44 can approach the bottle mouth as the cleaning support seat 42 moves, and when the bottle 9 rotates, the cleaning liquid can be sprayed on the outer wall of the bottle. After the washing is completed, the air jet 45 can blow air on the outer wall of the bottle 9 to accelerate the drying speed of the bottle body. In some embodiments, the spray head 44 and the air jet 45 can be arranged side by side or integrally, and the brush 43 can be located at the lower side of the spray head 44 and the air jet 45.

[0101] In the embodiment of the bottle washing device disclosed above, part of the outer contour of the bottle 9 is substantially a cuboid, and the bottle mouth is round, such as a square bottle for holding fermented bean curd. In other embodiments, the bottle 9 may also be other shapes.

[0102] Combine the following Figure 1-Figure 6 Let's illustrate the working process of an example of bottle washing equipment.

[0103] First, the bottle 9 containing the semi-finished fermented bean curd is passed through a conveyor belt from Figure 1The bottle 9 input to the bottle washing device is clamped by the paired bottle clamping belts 51 and moves to the position of the corresponding rotating base 3 along with the bottle clamping belts 51. The counter 61 counts the bottles 9 entering the bottle clamping belts 51, and when the preset value is reached, the interception member 62 intercepts the bottles 9 that do not enter the bottle washing device.

[0104] The paired bottle clamping belts 51 rotate to move each bottle 9 to the top of each rotating base 3 and then stop rotating. Then, the bottle pressing frame 34 is driven downward by the bottle pressing drive mechanism 32 to drive each bottle pressing head 35 to press into and press the bottle mouth of each bottle 9. Then, the paired bottle clamping belts 51 are moved away from each other to release each bottle 9 from being clamped. At this time, the cleaning support seat 42 and the brush 43, the spray head 44 and the air jet head 45 arranged thereon are driven by the cleaning drive mechanism 41 to move toward each bottle 9. Then, the liquid spray valve associated with the spray head 44 is started, and the support platform 25 of the rotating base 2 is rotated to drive the bottle 9 to rotate, so that the sprayed cleaning liquid can be evenly sprayed on the outer wall of the bottle in the circumferential direction, and the brush 43 can wash the outer wall. After the bottle is rotated at least one circle, for example, 20 circles, the liquid spray valve is closed, and the air jet valve associated with the air jet head 45 is opened to blow air to the bottle to dry the water and prevent the water from flowing into the bottle after the bottle pressing head is opened.

[0105] Then, the cleaning driving mechanism 41 drives the cleaning support seat 42 away from each bottle 9, and the paired bottle clamping belts 51 move toward each other to clamp each bottle 9, and then the bottle pressing frame 34 is driven upward by the bottle pressing driving mechanism 32 to drive the bottle pressing head 35 to separate from the bottle mouth. Then, the bottle clamping belts 51 rotate to gradually transport each bottle to the left side to the downstream conveyor belt. At the same time, another batch of bottles enters the bottle washing device for the next group of washing.
