[0040] The loading unit includes a second conveyor belt 21 corresponding to the turntable assembly.

[0041] Each driving mechanism can adopt a hydraulic cylinder or a pneumatic cylinder. Of course, for the main working mechanism, the second driving mechanism of the compression station and the third driving mechanism in the capping unit can adopt a gas-liquid booster cylinder. Those skilled in the art can choose according to their needs as long as the corresponding driving operation is achieved.

[0042] The conveyor belt assembly includes a front conveyor frame 22 and a rear conveyor frame 23. A driving cylinder 24 is mounted on the front conveyor frame, a driven cylinder is mounted on the rear conveyor frame, and a motor 25 for driving the driving cylinder to rotate is fixed on the front conveyor frame. The front conveyor frame and the rear conveyor frame can also be an integral mounting frame, which is fixed on a fixed frame and can realize the transmission of the carrier plate.

[0043] The above-mentioned turntable assembly includes a turntable body 26 and a driving assembly 27 for driving the turntable body to rotate. The loading station, pre-compression station, compression station and unloading station are evenly arranged around the center of the turntable body. Usually, the driving assembly includes a four-division indexer, which is driven by a motor. The indexer controls the rotation angle of the turntable body at each action (in the invention, the turntable body rotates 90° at each action).

[0044] The above-mentioned first pressing head includes a first driving seat 28, and a guide column 29 is provided at the upper end of the first driving seat. The guide column cooperates with the through hole on the fixing frame to realize the guiding effect and ensure the accuracy of the action of the first pressing head. The lower end of the first driving seat is fixed with a first pressing plate 31 through a connecting column 30, and a plurality of pressing rods 32 are fixed on the lower side of the pressing plate. Each pressing rod corresponds to each hole position 51 for placing the bottle body on the carrying plate at the work station. When the first pressing head is pressed down, the pressing rod extends into the bottle body to realize the pre-compression of the dry towel.

[0045] The second pressing head comprises a second driving seat 33, a guide column 34 is arranged at the upper end of the first driving seat, the guide column cooperates with the through hole on the fixing frame to realize the guiding function, and ensure the accuracy of the second pressing head action, a plurality of pressing columns 35 are fixed on the lower side of the second driving seat, each pressing column corresponds to each hole position for placing the bottle body on the carrier plate at the station, and a plurality of auxiliary pressing plates 36 are symmetrically arranged on the lower side of the second driving seat, each pressing plate is fixed with a guide column 37, and a retaining seat 38 is arranged on the upper side of the second driving seat corresponding to the guide column, when the second pressing head is pressed down, the guide column will extend into the bottle body to compress the dry towel in the bottle body;

[0046] A spring 39 is provided between the second drive seat and the auxiliary pressure plate. The spring is sleeved on the guide column, with its upper end against the second drive seat and its lower end against the auxiliary pressure plate. A lock nut 40 is provided at one end of the guide column passing through the retaining seat. The guide column and the retaining seat are slidably matched in the vertical direction. The lock nut limits the guide column from being separated from the retaining seat and ensures that the spring has a certain pre-compression force, ensures that the spring has good buffering performance, can exert the designed elastic force, and avoid excessive compression.

[0047] In an optional embodiment, in order to improve the versatility of the second pressure head part, the pressure column can be designed as a segmented structure, and each two segment ends are connected by threaded connection or other connecting parts (pins or screws). As an example, the threaded connection structure between the two segments can be: the lower end of the first pressure column segment fixed on the second driving seat is provided with an external thread structure, and the other end of the other detachable pressure column segment is provided with an internal thread structure connected to the external thread structure, and the other end is designed as a thread structure identical to the external thread structure, so as to ensure that each segment can be spliced ​​at will. In actual production operations, the pressure column (segment) of corresponding height can be configured according to the depth of the bottle body, which improves the versatility of the compression production equipment. Of course, the length of each segment can be different, for example, 5cm, 6cm, 7cm... and so on, with a large choice and better versatility. When adjusting the height of the pressure column, the lock nut can be screwed to adjust the spring elasticity to adapt to the elastic force requirements of the pressure column at different heights. It should be noted that the upper part of the pressure column is an external thread structure, and the lock nut thread is screwed on the upper part of the pressure column.

[0048] In an optional embodiment, a pressure sensor is further provided on the lower side of the auxiliary pressing plate, and the pressure sensor is connected to the main control unit of the device. When the pressing force reaches the set upper limit value during the compression of the dry towel, a signal is immediately fed back to the main control unit. After receiving the pressure information, the main control unit issues an instruction to stop the downward pressing action of the second driving mechanism, which has a higher degree of automation and better compression production quality. The main control unit in this embodiment is a single-chip microcomputer system in the device, and receiving pressure signals and issuing instructions is a common function of the single-chip microcomputer system, which belongs to the scope of the prior art, and therefore, will not be described in detail.

[0049] It should be noted that a fixing frame 41 is provided at the press unit, and baffles 45 are arranged around the fixing frame. A door body 46 can be set at the corresponding operating position, and a hollow space can also be reserved to facilitate production operations. This belongs to the scope of the prior art and will not be described in detail.

[0050] The guide column is generally matched with the top plate on the top of the fixing frame, and a through hole matched with the guide column is opened on the top plate. Of course, a matching seat 35 can also be set on the fixing frame to achieve matching with the guide column. Technical personnel in this field can also design it according to needs.

[0051] In order to ensure structural stability, as an example, the capping unit includes a frame 47, and the third driving mechanism and the capping seat are both fixed on the frame.

[0052] In an optional embodiment, the third pressing head includes a third driving seat 42, a third pressing plate 43 is fixed at the lower end of the third driving seat, and a buffer pad 44 is fixed at the lower side of the third pressing plate. A matching column 52 for guiding can also be provided on the upper side of the third driving seat, and the matching column matches with a through hole on the frame. When the third pressing head is pressed down, the bottle cap can be pressed on the bottle body, and the buffer pad plays a role of buffering and shock absorption, avoiding excessive impact on the bottle body, and effectively reducing the damage rate.

[0053] It should be noted that the structural design of the bottle cap and the bottle body and the installation of the bottle cap belong to the existing technology, and the operation of installing the bottle cap on the bottle also belongs to the scope that can be realized by the existing technology. Therefore, according to the design of different bottle caps and bottle mouths, technical personnel in this field can select the corresponding existing capping device. The above embodiment only lists one implementation form and is not exhaustive.

[0054] During production, this equipment can achieve the minimum labor usage. With the minimum staffing, only one person needs to be set up between the feeding unit and the pressing unit (the person takes the carrier plate with bottles from the loading unit and puts it into the loading station, and can also take down the carrier plate from the unloading station and put it on the first conveyor belt of the conveying unit), and one person needs to be set up between the pressing unit and the capping unit (the person buckles the bottle caps on each bottle body in turn), and the dry towel compression production operation can be completed. In order to reduce the labor intensity of workers and optimize production operations, a person can usually be set up at the discharge end of the conveying unit to take down the carrier plate with bottles from the conveying unit and put it into the transfer vehicle.

[0055] Each of the above-mentioned staff members can be directly replaced by a manipulator. For example, in an optional embodiment, a material unloading tool 22 is provided at the corresponding unloading station, and the material unloading tool is driven to move in the vertical direction by a fourth driving mechanism 48, and the fourth driving mechanism is installed on a slide 49, and the slide can be fixed on a fixed frame. The slide is driven by a fifth driving mechanism 50 to move along the conveying direction of the conveying unit. The fourth driving mechanism and the fifth driving mechanism can both adopt hydraulic cylinders, air cylinders or electric cylinders. Of course, those skilled in the art can also adopt other driving structure forms, as long as they can realize driving the material unloading tool to perform actions in the corresponding direction.

[0056] It should be pointed out that the unloading tool can adopt a robot that can clamp the carrier plate in the prior art. Of course, it can also be other mechanical structures that can grab the carrier plate on the unloading station of the turntable assembly and place it on the first conveyor belt. Those skilled in the art can choose according to their needs. As long as the robot can complete the designated operation of the corresponding station, the degree of automation can be further improved, labor costs can be reduced, and the error rate of human operation can be reduced.

[0057] This equipment can be directly connected with the next production process (for example, connected with the bottle labeling equipment, the bottles with compressed dry towels output from the conveying unit directly enter the labeling process for labeling operation). The bottles with bottle caps put on enter the capping unit for capping operation. After the capping is completed, the first conveyor belt continues to convey and output the bottled products.

[0058] The invention has a reasonable structural design. The pressing unit adopts the form of a turntable. The loading station, pre-compression station, compression station and unloading station are arranged in sequence. The process arrangement is more flexible, the labor consumption is reduced, the labor cost is saved, and the error rate caused by manual operation is reduced. The loading, pressing and unloading are combined in an orderly manner, the integration is high, the space occupied is small, and the production efficiency can be effectively improved.

[0059] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.

[0060] Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the invention is limited by the appended claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the invention. Any reference numerals in the claims should not be regarded as limiting the claims involved.

[0061] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
