[0034] It should be noted that the features in the embodiments of the present invention can be combined with each other without conflict.

[0035] In cold storage operations, quickly separating the frozen items from the carrier tray and then performing subsequent processing or packaging on the frozen items is a very important step. Currently, a tray removal machine is commonly used to quickly separate the frozen items from the carrier tray, and the tray removal machine includes a chain plate conveying structure. Since the current chain plate conveying structure is easily affected by temperature differences and expands and contracts thermally, existing chain plate conveying structures are all provided with chain plate tensioning devices. However, when adjusting the tension of the existing chain plate tensioning device, the shape of the chain plate is likely to change, affecting the tensioning and item transmission effects.

[0036] Based on this, please refer to Figure 1 and Figure 2 , the chain plate tensioning device 1000 provided in the embodiments of the present invention can effectively improve the above-mentioned technical problems. The chain plate tensioning device 1000 can adjust the inflection point position of the chain plate 100 by changing the position of the tensioning shaft 500 to meet the requirements of various working conditions, and can also achieve stable tensioning of the chain plate 100. The chain plate tensioning device 1000 in this embodiment is mainly applied to the tray removal machine, and the tray removal machine with this chain plate 100 device also has the above functions.

[0037] The tray removal machine in this embodiment includes a vibration device, a heating device, and a chain plate tensioning device 1000 connected in sequence. Of course, a chain plate tensioning device 1000 can also be provided between the vibration device and the heating device. In addition, the tray removal machine can also include other devices according to actual usage requirements, which are not limited herein.

[0038] In addition, the chain plate tensioning device 1000 in this embodiment can be used not only for the tray removal machine but also for other fields that require a 100-type chain plate conveyor, such as the continuous conveying, distribution, and post-packaging connection of the automatic conveying of some foods, canned foods, pharmaceuticals, beverages, cosmetics and toiletries, paper products, seasonings, dairy products, and tobacco.

[0039] Figure 1 It is a perspective schematic diagram of the chain plate tensioning device 1000 provided in the embodiment of the present invention; Figure 2 It is a schematic diagram of the chain plate 100 device removing the mounting frame 200 provided in the embodiment of the present invention. As Figure 1 and Figure 2 shown, the chain plate tensioning device 1000 in this embodiment includes a chain plate 100, a mounting frame 200, a limit guide rail 300, a drive shaft 400, and a tensioning shaft 500. The mounting frame 200 is arranged on both sides of the chain plate 100; the limit guide rail 300 is fixedly connected to the mounting frame 200, and part of the chain plate 100 is closely fitted with the limit guide rail 300; the chain plate 100 is fixedly connected to the mounting frame 200 through the drive shaft 400; the chain plate 100 is movably connected to the mounting frame 200 through the tensioning shaft 500, and the tensioning shaft 500 can move relative to the mounting frame 200. The drive shaft 400 is installed at one end of the chain plate 100, and a tensioning shaft 500 is installed at the end of the chain plate 100 away from the drive shaft 400. The drive shaft 400 is used to connect to an external driving member, such as a motor, a motor, etc. The driving member drives the drive shaft 400 to rotate to drive the chain plate 100 to transmit.

[0040] The chain plate 100 is movably connected to the mounting frame 200 through the tensioning shaft 500, and the tensioning shaft 500 can move relative to the mounting frame 200. By setting the tensioning shaft 500 and changing the position of the tensioning shaft 500, the inflection point position and tension degree of the chain plate 100 can be changed to meet the requirements of various working conditions. By setting the limit guide rail 300, part of the chain plate 100 can be limited, and the shape of the chain plate 100 at this place can be restricted. When adjusting the position of the tensioning shaft 500, because the limit guide rail 300 limits part of the chain plate 100 and restricts the shape of the chain plate 100 at the closely fitted place, the adjustment of the tensioning shaft 500 is also restricted to a certain extent, so as to ensure the stable tension of the chain plate 100 and prevent the influence on the tensioning and item transmission effects due to improper adjustment of the position of the tensioning shaft 500.

[0041] In order to utilize gravity to facilitate the conveying of items and to have a buffering effect during the conveying process, please continue to refer toFigure 1 and Figure 2 In this embodiment, the limiting guide rail 300 is semi-circular arc-shaped. Designing the limiting guide rail 300 as a semi-circular arc can make the chain plate 100 in close contact with the limiting guide rail 300 form a certain slope, and this part is similar to a chamfer, which is a gentle slope and has a certain buffering effect, which can prevent the items from falling rapidly during the downward conveying process and causing damage. For the convenience of installation and to achieve the close fit between the chain plate 100 and the limiting guide rail 300, the limiting guide rail 300 in this embodiment includes multiple circular arc-shaped guide rails connected in sequence, and the multiple circular arc-shaped guide rails together form a semi-circular arc-shaped guide rail. The multiple circular arc-shaped guide rails are all minor arc-shaped. Designing the limiting guide rail 300 as a semi-circular arc can ensure that the radius of the chain plate 100 increases evenly without changing the center position.

[0042] Of course, the limiting guide rail 300 can also be a linear guide rail. However, this limiting guide rail 300 forms an angle with the X direction, that is, the horizontal direction, such as an angle of 10°, 20°, 30° or 45° with the negative X direction, etc., but not exceeding 90°. The limiting guide rail 300 can also be combined into other shapes by two or more straight guide rails or a combination of straight guide rails and arc guide rails that are angled with each other according to actual conveying requirements, and this is not limited here.

[0043] Please refer to Figure 1 and Figure 2 Regarding the above-mentioned "the limiting guide rail 300 is fixedly connected to the mounting frame 200", for the convenience of installation and subsequent replacement and maintenance, the mounting frame 200 and the limiting guide rail 300 are detachably connected. Specifically, in this embodiment, a plurality of threaded holes 310 are provided on the limiting guide rail 300, and a plurality of mounting holes 210 are provided at the positions corresponding to the threaded holes 310 on the mounting frame 200. The mounting frame 200 and the limiting guide rail 300 are connected by a threaded fastener passing through the mounting hole 210 and the corresponding threaded hole 310. The threaded fastener can be a screw, a bolt, etc., and this is not limited here. Of course, the mounting frame 200 and the limiting guide rail 300 can also be connected by a snap connection method. In addition, the limiting guide rail 300 can also be welded to the mounting frame 200, and this is not limited here.

[0044] To meet the requirements of various working conditions, please continue to refer to Figure 1 and Figure 2, in this embodiment, the number of the tensioning shafts 500 is multiple, and the multiple tensioning shafts 500 are arranged at intervals to tension different positions of the link plate 100. Specifically, the link plate 100 in this embodiment includes a front surface 110 that fits against the limiting guide rail 300 and a back surface 120 that is away from the limiting guide rail 300. The tensioning shaft 500 includes a first tensioning shaft 510, a second tensioning shaft 520, and a third tensioning shaft 530. The first tensioning shaft 510 and the second tensioning shaft 520 are in contact with the back surface 120, and the third tensioning shaft 530 is in contact with the front surface 110. The mounting frame 200 is provided with a first adjustment slot 220, a second adjustment slot 230, and a third adjustment slot 240. The first tensioning shaft 510 is installed in the first adjustment slot 220 and can move within the first adjustment slot 220; the second tensioning shaft 520 is installed in the second adjustment slot 230 and can move within the second adjustment slot 230; the third tensioning shaft 530 is installed in the third adjustment slot 240 and can move within the third adjustment slot 240. The third tensioning shaft 530 is arranged in contact with the limiting guide rail 300. The adjustment slots in this embodiment are in the shape of waist-shaped holes. Of course, the adjustment slots can also be designed in other shapes according to the actual adjustment situation, such as cross-shaped, "L"-shaped, etc., which are not limited here.

[0045] To meet the tensioning requirements of the link plate 100, the first adjustment slot 220 in this embodiment extends along the X direction; the extending direction of the second adjustment slot 230 forms an angle with the X direction; the extending direction of the third adjustment slot 240 forms an angle with the X direction. Specifically, the extending direction of the second adjustment slot 230 in this embodiment forms a 135° angle with the positive X direction; the extending direction of the third adjustment slot 240 forms a 45° angle with the positive X direction. In this embodiment, due to the setting positions of the second tensioning shaft 520 and the third tensioning shaft 530, the extending directions of the second adjustment slot 230 and the third adjustment slot 240 are mirror-symmetrical. Of course, according to the actual setting positions of the first tensioning shaft 510, the second tensioning shaft 520, and the third tensioning shaft 530, the extending directions of the first adjustment slot 220, the second adjustment slot 230, and the third adjustment slot 240 can also be correspondingly changed to meet the tensioning requirements of the link plate 100. The extending directions of the first adjustment slot 220, the second adjustment slot 230, and the third adjustment slot 240 can also form other angles such as 30°, 45°, 120°, 145° with the positive X direction, which are not limited here.

[0046] Of course, the set number of the tensioning shafts 500 is not limited. The number of the tensioning shafts 500 can be set to two, four, five, etc. multiple tensioning shafts 500 according to actual needs, which are not limited here. The setting of the tensioning shafts 500 can also be determined according to specific conveying and tensioning requirements, which are not limited here.

[0047] According to a link plate tensioning device 1000 provided by this embodiment, its working principle is as follows:

[0048] Adjust the position of the tensioning shaft 500 relative to the mounting bracket 200 to change the inflection point of the link plate 100, thereby changing the tension degree of the link plate 100 to meet the requirements of various working conditions. Since some of the link plates 100 are in close contact with the limit guide rail 300, therefore, the adjustment position of some of the tensioning shafts 500 is limited. During the adjustment process, it is also necessary to ensure that the link plate 100 is in close contact with the limit guide rail 300, so as to achieve the stable tensioning of the link plate 100 and prevent the improper adjustment position of the tensioning shaft 500 from affecting the tensioning and article transmission effects.

[0049] In summary, the link plate tensioning device 1000 includes a link plate 100, a mounting bracket 200, a limit guide rail 300, a drive shaft 400, and a tensioning shaft 500. The mounting bracket 200 is arranged on both sides of the link plate 100; the limit guide rail 300 is fixedly connected to the mounting bracket 200, and some of the link plates 100 are in close cooperation with the limit guide rail 300. The link plate 100 is fixedly connected to the mounting bracket 200 through the drive shaft 400. The link plate 100 is movably connected to the mounting bracket 200 through the tensioning shaft 500, and the tensioning shaft 500 can move relative to the mounting bracket 200. By setting the limit guide rail 300, some of the link plates 100 can be limited, and the shape of the link plate 100 at this place can be restricted. The drive shaft 400 is used to connect an external driving member to enable the link plate 100 to rotate during operation. By setting the tensioning shaft 500 and changing the position of the tensioning shaft 500, the inflection point position and tension degree of the link plate 100 can be changed to meet the requirements of various working conditions. Since the limit guide rail 300 is provided, therefore, the adjustment position of some of the tensioning shafts 500 is also limited to a certain extent. During the adjustment process, it is also necessary to ensure that the link plate 100 is in close contact with the limit guide rail 300, so as to achieve the stable tensioning of the link plate 100 and prevent the improper adjustment position of the tensioning shaft 500 from affecting the tensioning and article transmission effects.

[0050] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
