[0001] The utility model belongs to the technical field of tank body processing, and particularly relates to a precise positioning mechanism for a tank body. Background Art

[0002] Cans are sealable containers made of sheet metal, glass, plastic, cardboard, or a combination of these materials. They are used to store commercial food. They undergo specialized treatment to achieve commercial sterility, allowing them to be kept at room temperature for extended periods without spoiling. This type of packaged food is called canned food. The canning process involves filling, water injection, capping, and sterilization, with capping being a crucial step.

[0003] For example, an automatic can sealing machine with publication number CN206051497U includes a sealing machine body with a frame structure. A conveying platform for conveying cans is provided on the front side of the sealing machine body, and a conveyor belt is provided on the conveying platform. A slide bar for sealing and capping the cans is provided on the upper part of the sealing machine body. The slide bar passes through the middle of the sealing machine body. Both sides of the top of the slide bar are fixed to the sealing machine by tension springs. The top of the slide bar contacts the outer surface of the cam, and the cam is connected to the drive motor by a belt. The applicant believes that the following deficiencies still exist:

[0004] When the above-mentioned device is in use, the can body needs to be transferred to a designated position before sealing the can body, and then the sealing operation is performed. However, due to insufficient design of the positioning structure, the can body may not be transferred to the position directly below the sealing component, resulting in poor sealing effect, low work efficiency and even waste of resources. Utility Model Content

[0005] The purpose of the utility model is to provide a precise positioning mechanism for a can body, which can position the can body to a position directly below the sealing assembly through a first positioning mechanism and a second positioning mechanism before the can body is conveyed to the sealing assembly for sealing using a conveyor belt, and no manual intervention is required during the process, thereby reducing errors, improving work efficiency and avoiding waste of resources.

[0006] The technical solutions adopted by this utility model are as follows:

[0007] A precise positioning mechanism for a tank body comprises two support plates, which are arranged opposite each other. A first positioning mechanism is provided in the middle of the support plates. A connecting plate is fixedly connected between the two support plates. A fixing seat B is symmetrically fixedly connected to the outer sides of the two support plates. A second positioning mechanism is provided in the middle of the connecting plate and the two fixing seats B. Axial holes are symmetrically opened on both sides of the support plates to pass through the support plates and connect to the inner cavity of the support plates.

[0008] As a preferred solution, the first positioning mechanism includes two roller motors, which are symmetrically arranged in the inner cavity of the support plate. The power output ends of the two roller motors are fixedly installed with a rotating shaft inserted into the shaft hole, and the outer side of the rotating shaft is fixedly connected to a rotating roller.

[0009] As a preferred solution, the second positioning mechanism includes three cylinders, two of which are symmetrically arranged on the surface of the fixed seat B, and the other cylinder is arranged on one side of the connecting plate. The power output end of the cylinder is fixedly connected to a telescopic piston rod, and the end of the telescopic piston rod is fixedly connected to an arc-shaped fixed plate.

[0010] As a preferred solution, a conveyor belt is provided between the two support plates, and the inner ends of the conveyor belt are respectively engaged with a driven roller and an active roller, and both ends of the driven roller and the active roller are movable through the support plates at corresponding positions.

[0011] As a preferred solution, a conveyor belt timing switch and a positioning control switch are provided on one side of the connecting plate, the active roller is electrically connected to the external power supply through the conveyor belt timing switch, and the cylinder is electrically connected to the external power supply through the positioning control switch.

[0012] As a preferred solution, the bottom of the support plate is fixedly connected to two support legs, and the two support legs are respectively fixedly connected to the two ends of the bottom of the support plate, one side of the connecting plate is fixedly connected to a fixed seat A, and a sealing assembly is provided at the bottom of the fixed seat A.

[0013] As a preferred solution, the two rotating rollers rotate in opposite directions and the side close to the conveyor belt is consistent with the direction of the conveyor belt. The rotating rollers are made of lightweight rubber.

[0014] The technical effects achieved by this utility model are:

[0016] The utility model is provided with a second positioning mechanism. After the conveyor belt timing switch and the positioning control switch are started, the three arc-shaped fixed plates perform a reciprocating motion at the same time. The cylindrical cavity formed by splicing together enables the can body to be accurately positioned directly below the sealing assembly, thereby improving the sealing effect, avoiding waste of resources and thus improving work efficiency.

[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0024] like Figure 1-4 As shown, a precise positioning mechanism for a tank body includes two support plates 1, which are arranged opposite to each other, and a first positioning mechanism 7 is provided in the middle of the support plate 1. Axial holes 14 are symmetrically opened on both sides of the support plate 1 to pass through the support plate 1 and connect to the inner cavity of the support plate 1. A conveyor belt 2 is provided between the two support plates 1, and the inner ends of the conveyor belt 2 are respectively engaged with a driven roller 6 and an active roller 5, and both ends of the driven roller 6 and the active roller 5 are movable through the support plates 1 at corresponding positions.

[0025] Refer to the attached Figure 1 、 Figure 4 , wherein the first positioning mechanism 7 includes two roller motors 73, and the two roller motors 73 are symmetrically arranged in the inner cavity of the support plate 1. At the same time, the power output ends of the two roller motors 73 are fixedly installed with a rotating shaft 72 inserted into the shaft hole 14, and the outer side of the rotating shaft 72 is fixedly connected to a rotating roller 71. The bottom of the support plate 1 is fixedly connected to two supporting legs 3, and the two supporting legs 3 are respectively fixedly connected to the two ends of the bottom of the support plate 1. One side of the connecting plate 11 is fixedly connected to a fixing seat A13, and the bottom of the fixing seat A13 is provided with a sealing assembly 12.

[0026] Among them, the two rotating rollers 71 rotate in opposite directions and both rotate toward the conveyor belt 2. The distance between the two rotating rollers 71 is set to be slightly larger than the diameter of the tank body. The rotating rollers 71 are made of lightweight rubber to ensure that when the tank body passes through the first positioning mechanism 7, it is facing the conveyor belt timing switch 9 and the positioning control switch 10 at the other end.

[0027] Refer to the attached Figure 4 According to the above structure, the device is connected to the power supply, the roller motor 73 is started, and the rotating shaft 72 fixedly connected to the power output end of the roller motor 73 begins to rotate, then the two rotating rollers 71 begin to rotate towards each other, and the can body is placed on the conveyor belt 2. By utilizing the rotation of the active roller 5, the conveyor belt 2 engaged with the active roller 5 begins to transport the can body toward the sealing position. When passing through the rotating rollers 71, if the can body is located between the two rotating rollers 71, it can pass through the first positioning mechanism 7 without contacting the rotating rollers 71.

[0028] If the can body is in contact with the rotating roller 71, the rotating roller 71 will cooperate with the conveyor belt 2 because the rotating roller 71 rotates in the opposite direction and the side close to the conveyor belt 2 is in the same direction as the conveyor belt 2, so that the can body is transported out from between the two rotating rollers 71.

[0029] Refer to the attached Figure 2-3 In order to more accurately position the can body at the sealing point, a connecting plate 11 is fixedly connected between the two support plates 1, and a fixing seat B4 is symmetrically fixedly connected to the outer sides of the two support plates 1. A second positioning mechanism 8 is provided in the middle of the connecting plate 11 and the two fixing seats B4.

[0030] Among them, the second positioning mechanism 8 includes three cylinders 81, two of which are symmetrically arranged on the surface of the fixed seat B4, and the other cylinder 81 is arranged on one side of the connecting plate 11. The power output end of the cylinder 81 is fixedly connected to the telescopic piston rod 82, and the end of the telescopic piston rod 82 is fixedly connected to the arc-shaped fixed plate 83. A conveyor belt timing switch 9 and a positioning control switch 10 are provided on one side of the connecting plate 11. The active roller 5 is electrically connected to the external power supply through the conveyor belt timing switch 9, and the cylinder 81 is electrically connected to the external power supply through the positioning control switch 10.

[0031] After the can body passes through the first positioning mechanism 7, it continues to be transported forward on the conveyor belt 2. When the can body abuts against the conveyor belt timing switch 9 and the positioning control switch 10 at the same time, the conveyor belt timing switch 9 will control the conveyor belt 2 to stop running for 5 seconds. At the same time, the positioning control switch 10 will simultaneously start the three cylinders 81. At this time, the three telescopic piston rods 82 will simultaneously drive the arc-shaped fixed plate 83 to perform a reciprocating motion at the same speed, forming a cylindrical cavity that matches the can body to jointly position the can body directly below the sealing assembly 12, thereby achieving precise positioning.

[0032] The working principle of the present invention is as follows: first, the power supply is connected, the roller motor 73 is started, and the rotating shaft 72 fixedly connected to the power output end of the roller motor 73 begins to rotate, then the two rotating rollers 71 begin to rotate in opposite directions, and the can body is placed on the conveyor belt 2. By utilizing the rotation of the active roller 5, the conveyor belt 2 meshing with the active roller 5 begins to transport the can body toward the sealing position. When passing through the rotating roller 71, if the can body is located between the two rotating rollers 71, it can pass through the first positioning mechanism 7 without contacting the rotating roller 71. If the position of the can body is in contact with the rotating roller 71, then because the rotating roller 71 rotates in opposite directions and the side close to the conveyor belt 2 is consistent with the direction of the conveyor belt 2, the rotating roller 71 will cooperate with the conveyor belt 2, so that the can body is transported out from between the two rotating rollers 71, ensuring that the can body can successfully abut against the conveyor belt timing switch 9 and the positioning control switch 10 after passing through the rotating roller 71.

[0033] Secondly, after the can body passes through the first positioning mechanism 7, it continues to be transported forward on the conveyor belt 2. When the can body abuts against the conveyor belt timing switch 9 and the positioning control switch 10 at the same time, the conveyor belt timing switch 9 will control the conveyor belt to stop running for 5 seconds and then run. At the same time, the positioning control switch 10 will simultaneously start the three cylinders 81. At this time, the three telescopic piston rods 82 will simultaneously drive the arc-shaped fixed plate 83 to perform a reciprocating motion at the same speed, forming a cylindrical cavity that matches the can body to jointly position the can body directly below the sealing assembly 12, thereby achieving precise positioning, so that the sealing assembly 12 can successfully seal the can body, reducing errors, improving work efficiency and avoiding waste of resources.

[0034] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
