Description

Technical Field

[0001] The utility model relates to the technical field of equipment positioning mechanisms, in particular to a turntable positioning mechanism and packaging equipment. Background Art

[0002] Sealing packaging machine is a machine that seals containers filled with packaging materials. After the product is loaded into the packaging container, in order to keep the product sealed and preserved, maintain product quality, and avoid product loss, the packaging container needs to be sealed. Because plastic has good heat sealing properties, this type of plastic is often used to make packaging containers, and then directly heat and apply pressure at the sealing point to make it fuse with paper or plastic and seal.

[0003] In order to reduce the occupied space and improve the production efficiency, the existing sealing and packaging machines will arrange the discharge station and the sealing processing station in sequence on the dividing plate along the circumferential direction, and then drive the dividing plate to rotate by the driving motor to seal and package the sealing processing stations on the dividing plate in sequence. In order to achieve the smooth sealing and packaging, positioning columns and positioning clips are generally provided on the packaging machine to cooperate to realize the positioning function.

[0004] However, in this positioning mechanism, when the positioning column and the positioning card are engaged, the positioning column will contact the positioning card. Since the positioning column is fixed on the dividing plate, this contact is hard contact. When running for a long time, the positioning column and the positioning card will be worn out due to the friction, resulting in a decrease in positioning accuracy, and the processing quality cannot be guaranteed, affecting the normal production of the packaging machine. Moreover, due to the wear and tear, the staff is required to frequently perform maintenance and replacement, which greatly reduces the production efficiency. Summary of the invention

[0011] In the above-mentioned turntable positioning mechanism, the rolling element is further provided with a plurality of limiting elements, and after the rolling element is mounted on the positioning column, it is connected and fixed to the turntable through the limiting elements.

[0012] In the above-mentioned turntable positioning mechanism, the positioning card is further provided with a positioning slot capable of rolling contact and engagement with the rolling member, and the outer ends of both side walls of the positioning slot are further symmetrically provided with guiding inclined surfaces.

[0013] In the above-mentioned turntable positioning mechanism, a guide member capable of guiding the positioning clamp and the positioning assembly to move closer to each other is further provided between the frame and the turntable.

[0014] In the turntable positioning mechanism as described above, the guide member includes side platforms symmetrically arranged on both sides of the positioning clamp and a limit platform arranged at one end between the two side platforms, and a guide groove capable of accommodating the positioning clamp is formed between the two side platforms and the limit platform.

[0031] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] See also Figure 1-2 , Figure 5-6 As shown, the embodiment of the present application provides a packaging device, including:

[0033] Rack 10;

[0034] A turntable 100 is rotatably disposed on the frame 10, and a plurality of workstations are disposed on the turntable 100 along the rotation direction;

[0035] A turntable driving mechanism 6, which is disposed on the frame 10 and is used to drive the turntable 100 to rotate;

[0036] An in-position detection mechanism 7, which is disposed between the frame 10 and the turntable 100 and is electrically connected to the turntable driving mechanism 6, and is used to detect the rotation in-position of the turntable 100;

[0037] And a turntable positioning mechanism, which is arranged between the frame 10 and the turntable 100 and is electrically connected to the in-position detection mechanism 7, and is used for limiting the rotation of the turntable 100 relative to the frame 10.

[0038] Furthermore, the turntable positioning mechanism includes:

[0039] A turntable positioning mechanism includes a positioning card 2 and a positioning assembly 3 movably arranged between a frame 10 and a turntable 100, and a driving assembly 4 capable of driving the positioning card 2 and the positioning assembly 3 to approach each other, wherein the positioning card 2 and the positioning assembly 3 are in rolling contact and engagement with each other to limit the turntable 100 from rotating relative to the frame 10.

[0040] When in use, the turntable driving mechanism 6 drives the turntable 100 to rotate. After the in-place detection mechanism 7 detects that the turntable 100 rotates to the position corresponding to the sealing station and the die, the turntable driving mechanism 6 is driven to stop working and the turntable 100 stops. At this time, the positioning component 3 moves to the positioning card 2, and then the driving component 4 starts to drive the positioning card 2 and the positioning component 3 to move closer to each other and roll and contact each other to limit the rotation of the turntable 100 relative to the frame 10, thereby completing the positioning of the turntable 100. The rolling contact setting between the positioning card 2 and the positioning component 3 not only makes the cooperation between the two smoother, but also avoids hard contact between the two during operation, greatly reduces the friction between the two, ensures the accurate positioning accuracy of the packaging equipment, and ensures the processing quality; and because the loss is greatly reduced, it also greatly reduces the maintenance and replacement times of the staff, thereby improving production efficiency.

[0041] Furthermore, the positioning assembly 3 includes a positioning column 31 and a rolling member 32 disposed on the positioning column 31, and the positioning column 31 is engaged with the positioning card 2 by rolling contact through the rolling member 32. The rolling contact setting between the rolling member 32 and the positioning card 2 not only makes the cooperation between the positioning column 31 and the positioning card 2 smoother, but also avoids hard contact between the two during operation, greatly reduces the friction between the two, ensures the accurate positioning accuracy of the packaging equipment, guarantees the processing quality, and greatly reduces the number of maintenance and replacement times of the staff due to greatly reduced loss, thereby improving production efficiency.

[0042] Specifically, the rolling element 32 includes one of a ball bearing, a needle bearing or a roller. Using one of a ball bearing, a needle bearing or a roller has low cost, is easy to purchase, and is convenient to assemble. In this embodiment, preferably, the rolling element 32 is a ball bearing.

[0043] More specifically, the positioning column 31 is disposed at the lower end of the rotating disk 100, and the rolling element 32 is detachably connected to the positioning column 31. The rolling element 32 and the positioning column 31 are detachably connected to facilitate assembly and disassembly of the positioning assembly 3. During maintenance and replacement, only the rolling element 32 needs to be disassembled without disassembling the positioning column 31, which is convenient and quick.

[0044] Furthermore, the rolling member 32 is provided with a plurality of stoppers 33, and the rolling member 32 is connected and fixed to the turntable 100 through the stoppers 33 after being mounted on the positioning column 31. The stoppers 33 are connected and fixed to the turntable 100 to facilitate maintaining the connection stability between the rolling member 32 and the positioning column 31 and between the rolling member 32 and the turntable 100, thereby preventing the rolling member 32 from falling and ensuring the normal operation of the device.

[0045] In this embodiment, the limiting member 33 is a cotter pin.

[0046] Furthermore, the positioning card 2 is provided with a positioning slot 20 that can be engaged with the rolling member 32 in rolling contact. The rolling member 32 and the positioning slot 20 are engaged in rolling contact to limit the movement of the rolling member 32 along the circumference of the turntable 100, thereby achieving positioning; and the rolling contact setting between the rolling member 32 and the positioning slot 20 not only makes the cooperation between the positioning column 31 and the positioning card 2 smoother, but also avoids hard contact between the two during operation, greatly reduces the friction between the two, ensures the accurate positioning accuracy of the packaging equipment, guarantees the processing quality, and greatly reduces the number of maintenance and replacement by the staff due to the greatly reduced loss, thereby improving production efficiency.

[0047] Specifically, the outer ends of the two side walls of the positioning slot 20 are symmetrically provided with guiding slopes 200. Through the guiding effect of the guiding slopes 200, the positioning component 3 can be more smoothly extended into the positioning slot 20, and slight error correction in the positioning process can be achieved, which is practical and convenient.

[0048] Furthermore, a guide member 5 is provided between the frame 10 and the turntable 100 to guide the positioning clamp 2 and the positioning assembly 3 to move closer to each other.

[0049] Specifically, the guide member 5 includes side platforms 51 symmetrically arranged on both sides of the positioning clamp 2, and a limit platform 52 arranged at one end between the two side platforms 51, and a guide groove 50 capable of accommodating the positioning clamp 2 is formed between the two side platforms 51 and the limit platform 52.

[0050] By setting the guide member 5, it is ensured that the positioning card 2 always slides in the same direction, avoiding the positioning card 2 from being offset, and further improving the accuracy of positioning. At the same time, through the limiting effect of the limit platform 52, it is ensured that the positioning card 2 always slides within the specified stroke, avoiding the occurrence of excessive stroke, ensuring that the positioning process proceeds smoothly, and is practical and convenient.

[0051] Furthermore, the two side platforms 51 are also provided with avoidance gaps 510 through which the positioning assembly 3 can pass. By setting the avoidance gaps 510, the positioning assembly 3 can smoothly enter the guide member 5 so as to be able to move to the positioning fixture 2, which is practical and convenient.

[0052] like Figure 3-4 As shown, in another embodiment, the guide member 5 includes side platforms 51 symmetrically arranged on both sides of the positioning card 2, and limiting flanges 53 respectively protruding on opposite sides of the two side platforms 51, and a guide groove 50 capable of accommodating the positioning card 2 is formed between the two side platforms 51 and the two limiting flanges 53. Specifically, the side platforms 51 and the limiting flanges 53 are integrally arranged to form an L-shaped guide structure. During installation, the two L-shaped guide structures are symmetrically arranged on both sides of the positioning card 2, and the distance between the two L-shaped guide structures can be adjusted according to the specific specifications of the positioning card 2; more specifically, during specific use, the distance between the two L-shaped guide structures can be adjusted accordingly according to the degree of wear of the positioning card 2, so as to avoid the formation of a gap between the positioning card 2 and the guide member 5, which affects the normal movement of the positioning card 2, and is practical and convenient.

[0053] Furthermore, the driving assembly 4 includes a push-pull device that can drive the positioning card 2 to perform reciprocating motion, and the positioning card 2 is connected to the moving end of the push-pull device. Specifically, in this embodiment, the driving assembly 4 can be a cylinder, and the positioning card 2 is connected to the telescopic end of the cylinder.

[0054] Furthermore, a positioning workbench 1 for installing the driving assembly 4 and the guide member 5 is also provided on the frame 10 .

[0055] Furthermore, the turntable driving mechanism 6 includes a first transmission gear 61 arranged below the turntable 100, a rotation driving motor 62 arranged on the frame 10, and a second transmission gear 63 arranged at the rotation output end of the rotation driving motor 62 and connected to the first transmission gear 61, so that the transmission is smooth.

[0056] Further, the in-position detection mechanism 7 includes a first sensor component 71 disposed on the frame 10 and located below the turntable 100, and a plurality of second sensor components 72 disposed below the turntable 100 along the circumference of the turntable 100 and capable of being opposite to the first sensor component 71. When the turntable 100 rotates until the second sensor components 72 are opposite to the first sensor components 71, the turntable driving mechanism 6 is driven to stop working, and the turntable positioning mechanism is driven to limit the rotation of the turntable 100. Optionally and non-limitingly, the first sensor component 71 can be a position sensor, and the second sensor component 72 can be an induction sheet.

[0057] In addition, the in-position detection mechanism 7 also includes a third sensor component 73 provided on the frame 10 and located below the turntable 100. The third sensor component 73 is arranged along the circumference of the turntable 100 relative to the first sensor component 71. When the turntable 100 rotates to the point where the second sensor component 72 is opposite to the first sensor component 71, the turntable driving mechanism 6 stops working. At this time, the turntable 100 still keeps rotating due to inertia. When the turntable 100 rotates to the point where the second sensor component 72 is opposite to the third sensor component 73, the turntable 100 stops rotating. The third sensor component 73 can ensure the accurate stopping of the turntable 100, thereby ensuring the effective positioning of the turntable positioning mechanism.

[0058] Furthermore, the in-position detection mechanism 7 also includes a detection mounting member 74 disposed on the frame 10, and the detection mounting member 74 is provided with a first detection mounting hole 740 for mounting the third sensor component 73, and second detection mounting holes 742 disposed on both sides of the first detection mounting hole for mounting the first sensor component 71. It is convenient for disassembly and assembly. The second detection mounting holes 742 are disposed on both sides of the first detection mounting hole, so that the first sensor component 71 can be installed left and right, that is, it can be flexibly adjusted and used when the station turntable rotates forward or reversely. At the same time, the second detection mounting hole 742 is arc-shaped, so as to facilitate the adjustment of the position of the first sensor component 71.

[0059] As described above, the embodiment of the present application provides a turntable positioning mechanism and packaging equipment. When in use, the turntable driving mechanism 6 drives the turntable 100 to rotate. After the in-position detection mechanism 7 detects that the turntable 100 rotates to the position corresponding to the sealing station and the die, the turntable driving mechanism 6 is driven to stop working and the turntable 100 stops. At this time, the positioning component 3 moves to the positioning card 2, and then the driving component 4 starts to drive the positioning card 2 and the positioning component 3 to move closer to each other and roll and contact each other to limit the rotation of the turntable 100 relative to the frame 10, thereby completing the positioning of the turntable 100. Moreover, through the rolling contact setting between the positioning card 2 and the positioning component 3, not only the cooperation between the two is made smoother, but also hard contact between the two during operation is avoided, thereby greatly reducing the friction between the two, ensuring the accurate positioning accuracy of the packaging equipment and ensuring the processing quality; and because the loss is greatly reduced, the maintenance and replacement times of the staff are also greatly reduced, thereby improving production efficiency.
