Description

Technical Field

[0001] The present invention relates to the technical field of filling equipment, in particular to a tea-filling and pressing equipment. Background Art

[0002] Currently, most automated filling lines are designed for powdered or liquid substances such as coffee, milk powder, and beverages. There are relatively few filling equipment for filling whole leaf tea into cans, and it is more difficult. First of all, there are many types of whole leaf tea, and their shapes are irregular. When the filling line automatically puts the tea into the can, due to the loose nature of the tea leaves and the small size of the can, the tea leaves are more likely to pop out of the edge of the can when they are put into the can. As a result, when the aluminum film is welded to the can to seal it, the "tea stuck" phenomenon is likely to occur, that is, the tea leaves are stuck between the aluminum film and the edge of the can. This causes the can seal to fail and defective products to appear. In addition, for whole leaf tea with large leaves, such as White Peony Tea, Shoumei Tea, Dahongpao Tea, etc., it is impossible to put the tea into the can with a smaller diameter when adding it.

[0003] At present, tea leaves are also crushed into granules or powders before filling. Although this is convenient for filling, it is different from the original shape of the leaves retained by the original leaf tea, and the taste of the tea is greatly affected after crushing. Summary of the Invention

[0004] The purpose of the present invention is to provide a tea filling and pressing device, which can press the original leaf tea put into the can body to prevent the tea leaves from being stuck between the sealing film and the edge of the can body, and at the same time increase the density of the tea leaves to avoid the phenomenon of being unable to be filled due to the loose state.

[0011] In a preferred embodiment of the present invention, the outer diameter of the pressing cylinder matches the inner diameter of the guide wall, and the inner diameter of the pressing cylinder is smaller than or equal to the inner diameter of the tea can.

[0012] In a preferred embodiment of the present invention, when the pressing cylinder is performing a tea pressing operation, the axis of the tea can coincides with the axis of the pressing cylinder.

[0037] The present invention provides a tea filling and pressing device, such as Figure 1 and Figure 2 As shown, it includes:

[0038] The conveying structure 10 is provided with a plurality of can molds 11 spaced apart along the transmission direction thereof, and each can mold 11 can be used to place a tea can 12 to be filled;

[0039] The first drive device 30 has a first drive shaft 31 that can move up and down. The first drive shaft 31 is connected to a guide plate 32. The guide plate 32 is located above the conveying structure 10. The lower part of the guide plate 32 is connected to a pressing cylinder 33. The pressing cylinder 33 can be interlocked with the can body mold 11 moved below it.

[0040] The second driving device 40 is connected to the guide plate 32 and has a second driving shaft 41. The second driving shaft 41 is axially movable and passes through the pressing barrel 33. One end of the second driving shaft 41 located in the pressing barrel 33 is connected to a pressing seat ring 42.

[0041] The present invention provides a first driving device 30 and a second driving device 40 on the upper part of the tea can 12 for pressing the tea leaves in the tea can 12, thereby preventing the tea leaves from being stuck between the sealing film of the tea can 12 and the edge of the can body, and at the same time increasing the density of the tea leaves contained in the tea can 12, avoiding the phenomenon of being unable to be filled due to a loose state; through the cooperation between the conveying structure 10, the first driving device 30 and the second driving device 40, continuous canning operations on the production line are realized, the production efficiency is high, and the labor cost of manual tea pressing operations is avoided.

[0042] Specifically, such as Figure 1 、 Figure 2 、 Figure 4 and Figure 6 As shown, a plurality of can molds 11 are fixed on the conveying structure 10 and installed closely in sequence. The can mold 11 is provided with a mounting groove 114 for placing the tea can 12. The mounting groove 114 is used to place the tea can 12 to be pressed into tea. The tea can 12 can follow the can mold 11 along the running direction of the conveying structure 10 to reach the filling and pressing station, and then complete the tea pressing operation under the action of the first drive device 30 and the second drive device 40. In this embodiment, the can mold 11 is a square block structure, and the lower part is fixedly installed on the conveying structure 10. A concave cylindrical mounting groove 114 is provided in the center of the upper surface of the can mold 11. The cylindrical tea can 12 can be placed inside the mounting groove 114. In this embodiment, the shape of the inner peripheral wall of the cylindrical mounting groove 114 matches the shape of the outer peripheral wall of the tea can 12, so as to improve the stability of the tea can 12 placed in the cylindrical mounting groove 114.

[0043] The first drive device 30 is arranged on one side of the conveying structure 10. The location of the first drive device 30 is the filling and tea pressing station. The first drive device 30 has a first drive shaft 31 that can move along the direction perpendicular to the conveying surface of the conveying structure 10. In this embodiment, the first drive device 30 is a pneumatic device driven by gas, and the first drive shaft 31 is a pneumatic shaft driven by the pneumatic device. A guide plate 32 is connected to the first drive shaft 31. The guide plate 32 is arranged parallel to the conveying surface of the conveying structure 10. The guide plate 32 can move up and down along the direction perpendicular to the conveying surface of the conveying structure 10 under the drive of the first drive shaft 31. In this embodiment, the guide plate 32 is a rectangular plate structure. One side of the upper end surface of the guide plate 32 is connected to the lower part of the first drive shaft 31. The guide plate 32 spans the entire conveying structure 10 in its length direction. A pressing barrel 33 is connected to the lower end face of the guide plate 32, and the axis of the pressing barrel 33 coincides with the axis of the tea can 12 parked at the filling and tea pressing station. The pressing barrel 33 can move up and down along the conveying surface perpendicular to the conveying structure 10 under the action of the first drive shaft 31, and can move downward to be interlocked with the can body mold 11 below it; in this embodiment, the pressing barrel 33 is a cylindrical tube structure, and its upper end face is fixedly connected to the lower end face of the guide plate 32, and the guide plate 32 is provided with a circular through hole connected to the pressing barrel 33 at the position corresponding to the pressing barrel 33.

[0044] The second drive device 40 is installed on the upper part of the guide plate 32. The second drive device 40 can move up and down along the conveying surface direction perpendicular to the conveying structure 10 under the drive of the first drive device 30. The second drive device 40 has a second drive shaft 41 that can move along the conveying surface direction perpendicular to the conveying structure 10. The axis of the second drive shaft 41 coincides with the axis of the pressing barrel 33, and the second drive shaft 41 passes through the circular through hole on the guide plate 32 and is movably arranged inside the pressing barrel 33; in this embodiment, the second drive device 40 is a pneumatic device driven by gas, and the second drive shaft 41 is a pneumatic shaft driven by the pneumatic device. The lower part of the second drive shaft 41 is connected to a pressing seat ring 42, which is located inside the pressing barrel 33 and can move up and down along the axis of the pressing barrel 33 under the action of the second drive shaft 41. The pressing seat ring 42 can be moved downward to the inside of the tea can 12 under the action of the second drive shaft 41 to perform tea pressing operations; in this embodiment, as Figure 6 As shown, the pressing seat ring 42 includes an upper connecting shaft 421 and a lower seat ring 422. The connecting shaft 421 is connected to the lower part of the first drive shaft 31, and the seat ring 422 is a circular ring structure that matches the internal space of the tea can 12.

[0045] In a feasible embodiment of the present invention, Figure 1 and Figure 4 As shown, the opening periphery of the can body mold 11 forms a limiting step 111 and a guide wall 112 protruding toward the pressing barrel 33. The guide wall 112 is located on the outer peripheral side of the limiting step 111. When the pressing barrel 33 is against the limiting step 111, the lower part of the pressing barrel 33 can extend into the guide wall 112.

[0046] A limiting step 111 and a guide wall 112 protruding toward the pressing cylinder 33 are formed around the mounting groove 114 for placing the tea can 12 opened on the can body mold 11. The setting of the limiting step 111 and the guide wall 112 can guide the pressing cylinder 33 to move downward under the action of the first drive shaft 31 until it abuts against the upper end surface of the tea can 12, and at the same time can ensure that the axis of the pressing cylinder 33 coincides with the axis of the tea can 12, so that the axis of the pressing seat ring 42 coincides with the axis of the tea can 12 when the tea pressing operation is performed, thereby ensuring the stability and accuracy of the tea pressing operation.

[0047] Specifically, such as Figure 4 As shown, a tea can 12 is placed inside the mounting groove 114 of the can body mold 11, and a limiting step 111 and a guide wall 112 protruding toward the pressing cylinder 33 are formed on the opening periphery of the can body mold 11. The guide wall 112 is located on the outer peripheral side of the limiting step 111, and the inner peripheral edge of the limiting step 111 is formed with a mounting step 113 that matches the edge of the tea can 12. When the mounting step 113 matches the edge of the can body of the tea can 12, the upper end face of the edge of the can body of the tea can 12 is flush with the limiting step 111. When the lower part of the pressing cylinder 33 abuts against the limiting step 111, it can abut against the opening edge end face of the can body of the tea can 12, thereby ensuring stability during the tea pressing process.

[0048] Further, such as Figure 4 and Figure 6 As shown, the outer diameter of the pressing cylinder 33 matches the inner diameter of the guide wall 112 , and the inner diameter of the pressing cylinder 33 is smaller than or equal to the inner diameter of the tea can 12 .

[0049] Limiting the outer diameter of the pressing barrel 33 within the inner diameter of the guide wall 112 ensures that the pressing barrel 33 can smoothly enter the guide wall 112 and abut against the limiting step 111 during the pressing operation, thereby fixing the tea can 12.

[0050] In a feasible embodiment of the present application, the axis of the tea leaf tank 12 coincides with the axis of the pressing cylinder 33 in the state that the pressing cylinder 33 is performing the tea pressing operation. When the pressing cylinder 33 internally penetrates the guide wall 112 downward in the tea pressing operation, the axis of the pressing cylinder 33 coincides with the axis of the tea leaf tank 12, and thus the axis of the pressing seat ring 42 located in the interior of the pressing cylinder 33 coincides with the axis of the tea leaf tank 12. In the tea pressing operation, the pressing seat ring 42 can be in direct cooperation with the tea leaf tank 12, and thus the accuracy of the tea pressing operation is realized.

[0051] In a feasible embodiment of the present application, the tea filling and pressing device further comprises a feeding cylinder 50, the lower side wall of the pressing cylinder 33 is provided with a feeding port 331, and the feeding cylinder 50 is provided with a discharging port 51. The shape of the feeding port 331 of the pressing cylinder 33 matches the shape of the discharging port 51 of the feeding cylinder 50.

[0052] The present application sets the feeding cylinder 50 on one side of the pressing cylinder 33, and tea can be filled into the interior of the tea leaf tank 12 through the feeding cylinder 50 and the pressing cylinder 33. The tea filling and pressing operation can be realized in the same station, and the tea can be directly fed into the interior of the tea leaf tank 12 without the need of setting a separate station, which makes the tea filling and pressing operation process of the tea leaf tank 12 relatively simple and improves the tea filling efficiency.

[0053] Further, in the state that the pressing cylinder 33 abuts against the tank body mold 11 and the pressing seat ring 42 is located above the feeding port 331 of the pressing cylinder 33, the discharging port 51 of the feeding cylinder 50 is in communication with the inner cavity of the pressing cylinder 33.

[0054] Specifically, as shown in Figure 4 and Figure 6 , the feeding cylinder 50 is fixed on the other side of the conveying structure 10 through a feeding cylinder frame 52. The feeding cylinder 50 is fixed and immovable. The lower part of the feeding cylinder 50 opposite to the pressing cylinder 33 is provided with the discharging port 51. The lower side wall of the pressing cylinder 33 is provided with the feeding port 331. When the feeding cylinder 50 moves downward to abut against the limiting step 111 under the action of the first driving device 30, the discharging port 51 on the feeding cylinder 50 is in communication with the feeding port 331 on the pressing cylinder 33. At this time, tea can be fed into the interior of the pressing cylinder 33 through the feeding cylinder 50, and then the tea is pressed into the interior of the tea leaf tank 12 through the pressing seat ring 42 driven by the second driving device 40.

[0055] In a feasible embodiment of the present application, as shown in Figures 1 to 6 , the lower part of the guide plate 32 is connected with a guide shaft 34. The tea filling and pressing device is provided with a rack 20, and the guide shaft 34 is axially movably arranged in the guide block 21 connected on the rack 20.

[0056] A guide shaft 34 that cooperates with the guide block 21 is provided at the lower part of the guide plate 32. The guide shaft 34 slides inside the guide block 21 to guide the guide plate 32 to move up and down, preventing it from deflecting during movement, thereby ensuring the stability of the tea pressing operation.

[0057] Specifically, such as Figure 1 As shown, the conveying structure 10 is arranged inside the frame 20, the feed drum 50 is fixed to one side of the frame 20 through the feed drum frame 52, and the other side of the frame 20 has a stand 22, the first drive shaft 31 is arranged on the top of the stand 22, the guide block 21 is fixed in the middle of the stand 22, and the guide shaft 34 is fixed on the lower side of the guide plate 32. The guide shaft 34 can be passed through the inside of the guide block 21 and can be moved up and down in a direction perpendicular to the conveying surface of the conveying structure 10 under the drive of the first drive shaft 31.

[0058] In a feasible embodiment of the present invention, Figure 4 As shown, the diameter of the pressing seat ring 42 is smaller than or equal to the inner diameter of the tea can 12 .

[0059] The diameter of the pressing seat ring 42 is limited to the inner diameter of the tea can 12 to ensure that it can move up and down inside the tea can 12, thereby achieving a stable tea pressing operation.

[0060] Furthermore, in a feasible embodiment of the present invention, the press seat ring 42 is a circular piston with elasticity. The elastic circular piston structure enables it to move up and down smoothly inside the press barrel 33, preventing the press seat ring 42 from getting stuck inside the press barrel.

[0061] In order to illustrate the characteristics and advantages of the tea filling and pressing equipment of the present invention, the following Figures 1 to 10 The filling and pressing tea process of the present invention is described in detail.

[0062] First, if Figure 7 As shown, the tea can 12 placed in the filling mold enters the filling and pressing tea station driven by the conveying structure 10. At this time, the tea can 12 is located directly below the pressing cylinder 33, and the discharge port 51 of the feed cylinder 50 is not connected to the feed port 331 of the pressing cylinder 33. The preparation work for filling and pressing tea has been completed.

[0063] Then, the filling and pressing tea operation is started, the first driving device 30 is started, the first driving shaft 31 moves downward, and at the same time drives the pressing cylinder 33 and the second driving device 40 to move downward until the bottom of the pressing cylinder 33 abuts against the limiting step 111 of the filling mold. Figure 8 In the state shown, at this time, the discharge port 51 of the feed cylinder 50 is connected with the feed port 331 of the pressing cylinder 33, the first driving device 30 is closed, and the first driving shaft 31 stops moving.

[0064] After the pressing cylinder 33 is in place, the tea filling operation begins, and the tea conveying mechanism (not shown) connected to the feeding cylinder 50 is started to feed the tea into the tea can 12 through the feeding cylinder 50 and the pressing cylinder 33.

[0065] After the tea leaves enter the tea can 12, the tea pressing operation is started, the second driving device 40 is started, and the second driving shaft 41 starts to move downward. Figure 9 As shown, the pressing seat ring 42 is driven by the second driving shaft 41 to enter the tea can 12 and press the tea leaves inside the tea can 12 to prevent them from getting stuck at the edge of the can body and affecting the sealing operation of the tea can 12. After one pressing, the pressing seat ring 42 can be raised to a certain height by the second driving device 40, such as Figure 10 As shown, the tea leaves are pressed down again. The compaction of the pressed tea can be adjusted by adjusting the downward pressing distance of the pressing ring 42, the number of times the tea leaves are pressed, and the duration of the pressing period when the pressing ring 42 is pressed down on the tea leaves. The greater the downward pressing distance of the pressing ring 42 and the more times the tea leaves are pressed, the denser the tea leaves are. The longer the pressing period, the less likely the tea leaves are to rebound after being pressed, and the denser they are.

[0066] After the above-mentioned filling and pressing tea operation is completed, the first driving device 30 is turned on, and the first driving shaft 31 moves upward, driving the second driving shaft 41 and the pressing cylinder 33 to separate from the can body mold 11, and then the conveying structure 10 transports the next tea can 12 with filling and pressing to the work station to continue the above-mentioned filling and pressing tea operation; the tea can 12 that has been completely filled and pressed at this work station will be transported by the conveying structure 10 to the next work station for operation.

[0067] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
