Description

Technical Field

[0001] This utility model relates to the field of radiation transportation technology, and specifically to a conveyor line alignment device. Background Technology

[0002] Radiation processing has become a mature modern technology after decades of development. Compared with sterilization technologies such as high temperature and ethylene oxide, radiation sterilization has advantages such as good penetration, can be carried out at room temperature, leaves no residue, and is easy to control. It is a green and efficient processing method and has been widely used in the irradiation sterilization of medical and health care products, irradiation preservation of food, and irradiation modification of polymer materials.

[0003] During irradiation processing, a transport line is used to feed the product into the labyrinth and down to the beam. There are two bends in the transport line as the product enters the labyrinth. Due to the transport on the first bend, the product's direction of travel deviates at an angle as it passes through, causing it to travel at a diagonal width on the second bend, which can cause large products to get stuck. Existing transport line technology cannot guarantee that the product can pass smoothly through two consecutive bends, significantly impacting processing efficiency. Utility Model Content

[0004] This invention provides a conveyor line alignment device to address the problems of existing technologies.

[0005] The objective of this utility model can be achieved through the following technical solution: a conveyor line alignment device, comprising: a conveyor frame and a plurality of conveyor rollers rotatably disposed within the conveyor frame, the conveyor frame including a linear conveyor frame and a corner conveyor frame, an alignment mechanism being provided on the linear conveyor frame, the alignment mechanism including a pushing component, a buffer component, and a positioning component, the pushing component including a pushing cylinder disposed on the side end of the linear conveyor frame, a lower pushing plate fixedly disposed on the end of the piston rod of the pushing cylinder, a connecting column disposed on the lower pushing plate, and an upper pushing plate disposed on the connecting column, the connecting column being provided in multiple sets, each set of the connecting columns being disposed between adjacent conveyor rollers, the buffer component including a first buffer plate disposed on the side end of the linear conveyor frame, a second buffer plate disposed on the first buffer plate, and a buffer spring disposed between the first buffer plate and the second buffer plate, the positioning component including a limiting cylinder disposed on the lower end of the linear conveyor frame and a limiting plate disposed on the lifting end of the limiting cylinder.

[0006] In a further improvement, the second buffer plate includes a buffer plate body and a threaded rod fixedly disposed on the side end of the buffer plate body. The threaded rod is slidably disposed on the first buffer plate and a limit nut is threadedly connected to its upper end. The limit nut is disposed on the side of the first buffer plate away from the second buffer plate.

[0007] In a further improvement, a guide plate is provided below the side end of the linear conveyor frame, the piston rod of the push cylinder passes through the guide plate and is fixedly connected to the lower push plate, a guide rod is slidably provided on the guide plate, and one end of the guide rod is fixedly connected to the lower push plate.

[0008] As a further improvement, the corner conveyor frame is provided with arc-shaped guide grooves on both sides, and guide wheels are rotatably installed in the arc-shaped guide grooves.

[0009] As a further improvement, the guide wheels are arranged in multiple sets with misalignment.

[0010] In a further improvement, an installation mechanism is provided on the side end of the arc-shaped guide groove. The installation mechanism includes an installation frame located above the side end of the corner conveyor frame and a threaded installation rod slidably mounted on the installation frame. The front end of the threaded installation rod is fixedly mounted to the side wall of the arc-shaped guide groove and an adjusting nut is provided above it. Two sets of adjusting nuts are provided, and the two sets of adjusting nuts are respectively located on both sides of the installation frame.

[0011] In a further improvement, the buffer assembly is provided in two sets, one set of which is corresponding to the push assembly, and the other set is provided at the intersection of the linear transport frame and the corner transport frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In actual use, the conveyor rollers on the linear conveyor frame transport the product forward. When the product passes the sensor, the limiting cylinder works, driving the limiting plate to rise and limiting the product. Then, the push cylinder works, driving the upper push plate to move, causing the product to move to one side of the push cylinder, thus returning the product to its correct position. During the return process, the side of the product abuts against the buffer assembly. The buffer springs between the first and second buffer plates work together to prevent damage to the product packaging during the return process. At the same time, a pressure sensor is installed on the second buffer plate. When the pressure sensor reaches the set value, the push cylinder retracts, the limiting plate falls, and the product is released. This allows the product to automatically return to its correct position on the conveyor frame, preventing deviation and rotation during continuous turns, which could cause the product to get stuck in the conveyor frame and affect the irradiation effect.

[0014] 2. This utility model can adjust the effective stroke of the buffer spring by adjusting the relative position of the limiting nut on the threaded rod, so that the equipment can adapt to products of different widths;

[0015] 3. This utility model can adjust the position of the arc-shaped guide groove by adjusting the relative positions of two sets of adjusting nuts, so that the equipment can adapt to products of different widths. It has a simple structure and is easy to operate. Attached Figure Description

[0024] The following is a description of the embodiments and appendices. Figures 1-5 The technical solution of this utility model will be further described below.

[0025] Example 1

[0026] A conveyor line alignment device includes: a conveyor frame 1 and a plurality of conveyor rollers 2 rotatably disposed within the conveyor frame 1. The conveyor frame 1 includes a linear conveyor frame 11 and a corner conveyor frame 12. An alignment mechanism 3 is disposed on the linear conveyor frame 11. The alignment mechanism 3 includes a pushing component 31, a buffer component 32, and a positioning component 33. The pushing component 31 includes a pushing cylinder 311 disposed on the side end of the linear conveyor frame 11, a lower pushing plate 312 fixedly disposed at the end of the piston rod of the pushing cylinder 311, a connecting column 313 disposed on the lower pushing plate 312, and a positioning component 33 disposed on the lower pushing plate 312. The connecting column 313 has an upward push plate 314 on it. Multiple sets of connecting columns 313 are provided. Each set of connecting columns 313 is arranged between adjacent transport rollers 2. The buffer assembly 32 includes a first buffer plate 321 arranged on the side end of the linear transport frame 11, a second buffer plate 322 arranged on the first buffer plate 321, and a buffer spring 323 arranged between the first buffer plate 321 and the second buffer plate 322. The positioning assembly 33 includes a limiting cylinder 331 arranged at the lower end of the linear transport frame 11 and a limiting plate 332 arranged at the lifting end of the limiting cylinder 331.

[0027] like Figures 1-5 As shown, in actual use, the conveyor rollers 2 on the linear conveyor frame 11 first transport the product forward. When the product passes the sensor, the limiting cylinder 331 works, driving the limiting plate 332 to rise and limit the product. Then, the pushing cylinder 311 works, driving the upper pushing plate 314 to move, causing the product to move to one side of the pushing cylinder 311, thus returning the product to its correct position. During the return process, the side of the product abuts against the buffer assembly 32. The buffer spring 323 between the first buffer plate 321 and the second buffer plate 322 works in tandem to prevent damage to the outer packaging of the product during the return process. At the same time, a pressure sensor is installed on the second buffer plate 322. When the pressure sensor reaches the set value, the pushing cylinder 311 retracts, and the limiting plate 332 falls, releasing the product and allowing it to automatically return to its correct position on the conveyor frame 1. This prevents the product from shifting or rotating during continuous turns, which could cause it to get stuck in the conveyor frame 1 and affect the irradiation effect.

[0028] As a further preferred embodiment, the second buffer plate 322 includes a buffer plate body 3221 and a threaded rod 3222 fixedly disposed on the side end of the buffer plate body 3221. The threaded rod 3222 is slidably disposed on the first buffer plate 321 and its upper end is threadedly connected to a limit nut 3223. The limit nut 3223 is disposed on the side of the first buffer plate 321 away from the second buffer plate 322.

[0029] Specifically, such as Figure 5 As shown, in actual use, the relative position of the limit nut 3223 on the threaded rod 3222 can be adjusted to adjust the effective stroke of the buffer spring 323, so that the equipment can adapt to products of different widths.

[0030] As a further preferred embodiment, a guide plate 111 is provided below the side end of the linear conveyor frame 11. The piston rod of the push cylinder 311 passes through the guide plate 111 and is fixedly connected to the lower push plate 312. A guide rod 112 is slidably provided on the guide plate 111. One end of the guide rod 112 is fixedly connected to the lower push plate 312. The stability of the equipment is improved by the guidance of the guide plate 111 and the guide rod 112.

[0031] As a further preferred embodiment, the corner transport frame 12 is provided with arc-shaped guide grooves 4 on both sides, and guide wheels 41 are rotatably arranged in the arc-shaped guide grooves 4. The stability of the product on the transport frame 1 is improved by limiting the arc-shaped guide grooves 4 and the guide wheels 41.

[0032] As a further preferred embodiment, the guide wheels 41 are provided in multiple sets with misalignment.

[0033] As a further preferred embodiment, an installation mechanism 5 is provided on the side end of the arc-shaped guide groove 4. The installation mechanism 5 includes an installation frame 51 disposed above the side end of the corner conveyor frame 12 and a threaded installation rod 52 slidably disposed on the installation frame 51. The front end of the threaded installation rod 52 is fixedly disposed to the side wall of the arc-shaped guide groove 4 and an adjusting nut 53 is disposed above it. Two sets of adjusting nuts 53 are provided, and the two sets of adjusting nuts 53 are respectively disposed on both sides of the installation frame 51.

[0034] Specifically, such as Figure 2 As shown, in actual use, the position of the arc-shaped guide groove 4 can be adjusted by adjusting the relative positions of the two sets of adjusting nuts 53, so that the equipment can adapt to products of different widths. The structure is simple and the operation is convenient.

[0035] As a further preferred embodiment, the buffer assembly 32 is provided in two sets, one set of which is corresponding to the push assembly 31, and the other set is provided at the intersection of the linear transport frame 11 and the corner transport frame 12.

[0036] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
