[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation to the present utility model and its application or use. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Such as Figures 1 to 4As shown in the figure, an embodiment of the present utility model provides a lid buckling device. The lid buckling device includes a container conveying assembly and a lid conveying assembly 10. The container conveying assembly includes a frame body and a conveyor belt disposed on the frame body. The conveyor belt has a plurality of container placement positions, and the plurality of container placement positions are sequentially arranged along the length direction of the conveyor belt. The lid conveying assembly 10 includes a conveying section 11, a swinging claw 12, and a reset member. The conveying section 11 is located above the container conveying assembly and is inclined. In the container conveying direction, the distance between the conveying section 11 and the container conveying assembly gradually decreases. The swinging claw 12 is swingably disposed at the outlet of the conveying section 11. The swinging axis of the swinging claw 12 is disposed at an angle with the extending direction of the conveying section 11. The reset member can provide a restoring force for the swinging claw 12 to swing the swinging claw 12 toward the direction close to the axis of the conveying section 11.

[0025] Applying the technical solution of the present utility model, the lid buckling device includes a container conveying assembly and a lid conveying assembly 10. Place the container on the container placement position of the conveyor belt, and use the conveyor belt to drive the container to move. Since the conveying section 11 is located above the container conveying assembly and is inclined, and in the container conveying direction, the distance between the conveying section 11 and the container conveying assembly gradually decreases, the upper lid can slide along the extending direction of the conveying section 11 under the action of gravity, and when sliding to the outlet of the conveying section 11, the swinging claw 12 can be used to limit the upper lid, so that the upper lid stays at the outlet of the conveying section 11 and partially exposes the outlet of the conveying section 11. During the process of the container moving along with the conveyor belt, since the upper lid is exposed, the container can contact the edge of the upper lid and apply a forward driving force to the upper lid. The upper lid presses the swinging claw 12, causing the swinging claw 12 to swing. Then, the upper lid can slide out from the outlet of the conveying section 11 and cover the container. At this time, under the action of the restoring force provided by the reset member, the swinging claw 12 swings toward the axis of the conveying section 11 and returns to the initial state to block and limit the next upper lid. Compared with the operation of manually covering the upper lid, it can improve production efficiency, reduce the rejection rate, and avoid the existence of containers without lids.

[0026] Wherein, the conveying section 11 and the conveyor belt extend in the same direction, and there is an included angle between them.

[0027] In this embodiment, an arc surface is disposed on one side of the swinging claw 12 facing the axis of the conveying section 11, and the arc surface is used to limit the upper lid so that the upper lid stays at the outlet of the conveying section 11.

[0028] Specifically, the swinging axis of the swinging claw 12 is perpendicular to the extending direction of the conveying section 11.

[0029] Such as Figure 2As shown, the conveying section 11 includes a slide groove 111 and a limit plate 112, the slide groove 111 and the limit plate 112 are both inclined, the limit plate 112 is located in the slide groove 111, the extension direction of the slide groove 111 is the same as the extension direction of the limit plate 112, and the interval between the slide groove 111 and the limit plate 112 together forms an upper cover channel. The conveying section 11 adopting the above structure can use the slide groove 111 to carry the upper cover, and use the limit plate 112 to press the upper cover, so that the upper cover can slide smoothly in the slide groove 111.

[0030] In this embodiment, in order to clearly observe the state of the upper cover in the slide groove 111 , there should be a lateral spacing between the limiting plate 112 and the slide groove 111 .

[0031] The cover conveying assembly 10 further includes a hanger, which includes a top plate and two side plates connected to both ends of the top plate, the two side plates are respectively located on both sides of the slide slot 111 and are respectively connected to both sides of the slide slot 111, and the top plate is located above the limit plate 112 and is connected to the limit plate 112. With the hanger of the above structure, the limit plate 112 can be connected to the slide slot 111 to form an upper cover channel.

[0032] In other embodiments, the limiting plate 112 may be connected to the slide groove 111 by using connecting bolts or other connecting members.

[0033] In this embodiment, the cover conveying assembly 10 further includes an adjusting rod, the position of which is adjustable and penetrates the top plate, and the lower end of the adjusting rod is connected to the limit plate 112. With the above arrangement, the height of the upper cover channel can be adjusted, so that it can be suitable for upper covers of different thicknesses, thereby widening the application range of the cover buckling device.

[0034] The adjusting rod can pass through the top plate in a threaded connection manner, and the position of the adjusting rod relative to the top plate can be adjusted by adjusting the length of the threaded portion.

[0035] like Figure 2 As shown, there are two swing claws 12, which are respectively arranged on both sides of the outlet of the conveying section 11, and the two swing claws 12 together form a limiting groove for limiting the upper cover. The two swing claws 12 can make the upper cover slide from the outlet of the conveying section 11 in a more stable sliding state without vibration, so that the upper cover can be stably buckled on the container.

[0036] In other embodiments, a swing claw 12 may be provided on one side of the outlet of the conveying section 11, and the conveying section 11 itself may be provided in an arc shape on the other side, so that the upper cover is limited by the cooperation of the conveying section 11 and the swing claw 12. Compared with the limiting method of this embodiment, when the upper cover slides out, the center of the upper cover may deflect and vibrate.

[0037] Specifically, the reset member includes a torsion spring, and the two torsion arms of the torsion spring are respectively connected to the frame body and the swing claw 12. The method of using the torsion spring to drive the swing claw 12 to automatically reset has the advantages of simple structure and convenient assembly.

Alternatively, a rotatable rotating shaft can be provided on the frame body, the torsion spring is sleeved on the rotating shaft, and the two torsion arms of the torsion spring are respectively connected to the frame body and the swing claw 12.

[0039] In this embodiment, the cover buckling device further includes an alarm member and a first detection member capable of detecting the position state of the upper cover. The first detection member is located above the conveying section 11, and the alarm member and the first detection member are signal-connected. By using the first detection member to detect the position state of the upper cover, it is possible to further determine whether the upper cover is in an inverted state. When the upper cover is in an inverted state, a signal is transmitted to the alarm member, and the alarm member is used to remind the staff to avoid the situation where the upper cover cannot be buckled on the container.

[0040] Among them, the first detection member is a ranging photoelectric sensor. The ranging photoelectric sensor can be arranged on the limiting plate 112 or on a separate bracket to support the ranging photoelectric sensor. The alarm member can be set as an alarm lamp or a buzzer.

[0041] As Figure 1 and Figure 4 shown, the cover conveying assembly 10 further includes a storage section 14, a limiting member 15, and a suction member 16. There is an included angle between the storage section 14 and the conveying section 11. The outlet of the storage section 14 is communicated with the inlet of the conveying section 11. The limiting member 15 is movably arranged in the storage section 14, and there is an included angle between the moving direction of the limiting member 15 and the extending direction of the storage section 14. The suction member 16 is located below the storage section 14 and can telescopically penetrate into the storage section 14. The suction member 16 can provide an adsorption force for the upper cover to move the upper cover from the storage section 14 to the conveying section 11. The storage section 14 can store multiple upper covers at the same time, and the limiting member 15 is used to contact and limit the lowermost upper cover, so that multiple upper covers are jointly retained in the storage section 14. The suction member 16 can adsorb the upper cover and move the upper cover from the storage section 14 to the conveying section 11.

[0042] In this embodiment, the diameter of the storage section 14 is slightly larger than the diameter of the upper cover.

[0043] Among them, the limiting member 15 can be set as a limiting claw, and the inner side of the limiting claw is set to be arc-shaped. When the suction member 16 drives the upper cover to move, the limiting claw moves by the force exerted on the limiting claw by the upper cover. Alternatively, the limiting claw is swingably arranged on the side wall of the storage section 14.

[0044] Specifically, a return spring providing a restoring force is provided between the limiting claw and the storage section 14, and a torsion spring can also be provided.

[0045] In this embodiment, there are multiple limiting claws, and the multiple limiting claws are arranged at intervals along the circumferential direction of the storage section 14.

[0046] As Figure 1 shown, the adsorbing member 16 includes a cylinder 161 and a suction cup. The suction cup is arranged at the front end of the cylinder 161, and the extending direction of the cylinder 161 is the same as the extending direction of the storage section 14. The adsorbing member 16 with the above structure has the advantages of simple structure and convenient operation.

[0047] In this embodiment, a second detecting member capable of detecting the number of upper covers is arranged in the storage section 14. The second detecting member is used to detect the number of upper covers to remind the staff to add upper covers in the storage section 14 in a timely manner.

[0048] Among them, the second detecting member is a detecting photoelectric. An alarm lamp or a buzzer connected to the detecting photoelectric signal can be set.
