[0031] Please refer to Figure 1 and Figure 2 , an embodiment of the present utility model provides a pet mat centering device, including: a frame 10, a conveying mechanism 20, a centering driving device 30 and two centering plates 40.

[0032] The conveying mechanism 20 is arranged on the frame 10 and is used for conveying the pet mat. The centering driving device 30 is arranged on the frame 10 and is drivingly connected to two centering plates 40. The two centering plates 40 are respectively arranged on both sides of the conveying path of the conveying mechanism 20. The two centering plates 40 move synchronously away from or towards each other under the driving of the centering drive. After the pet mat is placed on the conveying mechanism 20, the two centering plates 40 move synchronously towards each other under the driving of the centering drive, so as to clamp the pet mat at a predetermined position. Then, the two centering plates 40 move away from each other under the driving of the centering drive and disengage from the pet mat. Then, the conveying mechanism 20 conveys the pet mat to the next process. The predetermined position can be the middle position of the conveying mechanism 20 or other suitable positions of the conveying mechanism 20, so that the pet mat can be accurately moved to the next processing equipment at a suitable position. Since the staff only needs to place the pet mat on the conveying mechanism 20, or the production equipment directly feeds the pet mat onto the conveying mechanism 20, and then the position can be adjusted by the centering plates 40, which saves time and effort. Moreover, the two centering plates 40 move synchronously, which can make the positioning position of the pet mat more accurate.

[0033] Please refer to Figure 3 and Figure 4 , the specific structure of the centering driving device 30 can be designed according to actual needs. For example, in some alternative embodiments, the centering driving device 30 includes a driving motor 31, a transmission gear 32 and two transmission racks 33. The driving motor 31 is arranged on the frame 10 and is drivingly connected to the transmission gear 32. The two transmission racks 33 are respectively arranged on both sides of the transmission gear 32 and are meshed with the transmission gear 32. The transmission racks 33 are correspondingly connected to the centering plates 40. When the driving motor 31 drives the transmission gear 32 to rotate, the transmission gear 32 drives the two transmission racks 33 to move synchronously away from or towards each other, and further drives the centering plates 40 to move synchronously away from or towards each other through the transmission racks 33. The cooperation of the transmission gear 32 and the transmission racks 33 can more accurately control the moving position of the centering plates 40. Of course, the centering driving device 30 can also adopt two translation driving modules, and the translation driving modules are correspondingly drivingly connected to the centering plates 40. The translation driving modules can be screw driving modules, rotary motor translation driving modules, belt translation driving modules, cylinder translation driving modules or linear motor translation driving modules.

[0034] Since there is vibration when the centering plate 40 and the transmission rack 33 move, in order to avoid strong interference between the transmission rack 33 and the transmission gear 32, such as extrusion and collision, in some alternative embodiments, the transmission rack 33 is rotatably connected to the centering plate 40. When the centering plate 40 and the transmission rack 33 move, the centering plate 40 can rotate relative to the transmission rack 33 by an angle, so as to adapt to the position deviation caused by the vibration of the centering plate 40, and further avoid driving the transmission rack 33 to squeeze and collide with the transmission gear 32, thereby improving the structural stability.

[0035] Please refer to Figure 5 and Figure 6 In some alternative embodiments, the centering drive device 30 further includes two first limiting structures 34, and the first limiting structures 34 are correspondingly arranged on the side of the transmission rack 33 away from the transmission gear 32 to limit the transmission rack 33 from moving away from the transmission gear 32 in the radial direction of the transmission gear 32, so that the transmission rack 33 is not likely to move in the radial direction of the transmission gear 32 and disengage from the transmission gear 32. Especially when the transmission rack 33 and the centering plate 40 are rotationally matched, it is easy to cause the position of the transmission rack 33 to shift relative to the transmission gear 32. In this case, the position of the engagement between the transmission rack 33 and the transmission rack 33 can be stably limited, so that the transmission rack 33 can maintain a stable engagement with the transmission gear 32.

[0036] The specific structure of the first limiting structure 34 can be designed according to actual needs. For example, in some alternative embodiments, the first limiting structure 34 includes a first limiting wheel, and the first limiting wheel is rotatably arranged on the frame 10 and arranged on the side of the transmission rack 33 away from the transmission gear 32. When the transmission rack 33 moves, the first limiting wheel can roll relative to the transmission rack 33, thereby reducing the friction between the transmission rack 33 and the first limiting wheel and improving the service life of the transmission rack 33. Of course, the first limiting structure 34 can also adopt a first limiting block fixed on the frame 10, and the first limiting block can adopt an arc-shaped structure to reduce the contact area with the transmission rack 33, thereby reducing wear, and this is not limited to this example.

[0037] In some alternative embodiments, the centering drive device 30 further includes two second limiting structures 35, and the second limiting structures 35 are arranged on the frame 10. A limiting space is formed on the second limiting structure 35, and the transmission rack 33 movably passes through the limiting space to limit the transmission rack 33 from moving away from the transmission gear 32 in the axial direction of the transmission gear 32, so as to effectively maintain the position of the transmission rack 33 relative to the transmission gear 32, so that the transmission rack 33 can stably engage with the transmission gear 32.

[0038] The specific structure of the second limiting structure 35 can be designed according to actual needs. For example, in some alternative embodiments, the second limiting structure 35 includes two second limiting wheels 351, and the two second limiting wheels 351 are arranged side by side on the frame 10 and are rotationally matched with the frame 10. A limiting space is formed between the outer side surfaces of the two second limiting wheels 351. Of course, the second limiting structure 35 can also include two second limiting blocks fixed on the frame 10, and a limiting space is formed between the two limiting blocks. In addition, the sides of the two second limiting blocks facing each other can adopt an arc-shaped structure to reduce the contact area with the transmission rack 33, thereby reducing wear, and this is not limited to this example.

[0039] The specific structure of the conveying mechanism 20 can be designed according to actual needs. For example, in some alternative embodiments, the conveying mechanism 20 includes a conveying power module 21 and a plurality of conveying rollers 22, the conveying rollers 22 are rotatably engaged with the frame 10, the plurality of conveying rollers 22 are arranged in sequence along the conveying path of the conveying mechanism 20, the conveying power module 21 is drivingly connected to the conveying rollers 22, the centering plate 40 is located above the conveying rollers 22, the conveying power module 21 can adopt a motor to drive a tooth chain to move, a gear meshing with the tooth chain is arranged on the side of the conveying roller 22, the tooth chain drives the gear to rotate so as to realize the rotation of the conveying roller 22, and the rotation of the conveying roller 22 can drive the pet mat to move. Of course, the motor of the conveying power module 21 can also be meshed with the gear of the conveying roller 22 through a plurality of gear sets to realize transmission. Or, the conveying power module 21 can also adopt a plurality of motors, and the output shafts of the motors are directly drivingly connected to the conveying rollers 22. In addition, the conveying mechanism 20 is not limited to the form of the conveying roller 22, and the conveying mechanism 20 can also adopt a belt conveying mechanism 20, a chain plate conveying mechanism 20, etc., and this is not limited to this example.

[0040] In order to simplify the structure of the overall pet mat centering device and improve the aesthetic appearance, in some alternative embodiments, a plurality of slide rails 11 and two sliding seats 12 slidably engaged with the slide rails 11 are arranged on the frame 10, the slide rails 11 and the sliding seats 12 are arranged below the conveying rollers 22, a plurality of connecting rods 13 are arranged on the sliding seats 12, the connecting rods 13 pass through the gaps between adjacent two conveying rollers 22 and then are connected to the centering plate 40. The sliding seats 12 and the slide rails 11 can improve the stability of the movement of the centering plate 40, and by utilizing the certain gaps between adjacent conveying rollers 22, the sliding seats 12 and the slide rails 11 can be arranged below the conveying mechanism 20, so as to hide structures such as the sliding seats 12 and the slide rails 11, making the overall device look more tidy and beautiful. The transmission rack 33 can be directly connected to the centering plate 40 or can be connected to the sliding seat 12, so as to indirectly realize the transmission cooperation with the centering plate 40.

[0041] The above-mentioned pet mat centering device can be applied to a pet mat packaging machine, and the pet mat packaging machine includes: a pet mat centering device as described above. Usually, the pet mat packaging machine further includes a compressing device and a heat welding device. The pet mat centering device conveys the centered pet mat onto the compressing device, and after the outer packaging is sleeved, the compressing device compresses the pet mat, and then the outer packaging is heat welded to seal the outer packaging, and this is not limited to this example.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
