[0002] As people's living standards improve, most people will keep pets, such as cats, dogs, etc. In order to provide pets with a more comfortable living environment, people will buy pet mats. Pet mats are generally soft and elastic, and can provide pets with a more comfortable rest and play environment.

[0003] Current pet mats typically consist of an outer shell and inner filling. The outer shell is typically made of ice silk, cloth, or velvet, while the inner filling is typically made of cotton, wool, cloth, sponge, or other materials. Depending on the materials used for the outer shell and inner filling, the pet mat can either cool or insulate. However, because the inner filling is often fluffy, pet mats are often bulky and inconvenient to transport. Therefore, pet mats are often compressed and packaged to reduce their size.

[0004] Currently, before compressing and packaging pet mats, the packaging film needs to be pulled out a certain distance from the film storage mechanism, then cut, and then pulled out again. Currently, the packaging film is pulled out manually, which is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0032] See also Figure 1 One embodiment of the present invention provides a packaging film conveying device, including: a base 10, a film storage mechanism 20, a film clamping mechanism 30 and a film conveying mechanism 40.

[0033] See also Figure 2 and Figure 3 The film storage mechanism 20 is arranged on the base 10 for unwinding the packaging film; the film clamping mechanism 30 is arranged on the base 10, which includes a power component 31, a first clamping plate 32 and a second clamping plate 33. The first clamping plate 32 and the second clamping plate 33 are arranged on the base 10 and are located on one side of the film storage mechanism 20. The first clamping plate 32 and the second clamping plate 33 are clamped and matched under the drive of the power component 31. A plurality of avoidance notches 34 are provided on the first clamping plate 32 and the second clamping plate 33. When the two clamping plates 33 are in clamping cooperation, the avoidance gap 34 of the first clamping plate 32 and the avoidance gap 34 of the second clamping plate 33 jointly form a film grabbing gap 35; the film conveying mechanism 40 includes a grabbing component 41 and a transfer component 42, and the transfer component 42 is driven and connected to the grabbing component 41, and is used to drive the grabbing component 41 to approach or move away from the film grabbing gap 35. When the grabbing component 41 extends into the film grabbing gap 35 under the drive of the transfer component 42, the grabbing component 41 clamps the packaging film located in the film grabbing gap 35.

[0034] The packaging film stored on the film storage mechanism 20 extends into between the first clamping plate 32 and the second clamping plate 33, and part of the packaging film is exposed to the film grabbing notch 35. The grabbing component 41 extends into the film grabbing notch 35 and grabs the packaging film. Then the transfer component 42 drives the grabbing component 41 away from the film grabbing notch 35 so that the packaging film is pulled out. After the pulled-out packaging film is cut, the packaging film that has not been cut remains between the first clamping plate 32 and the second clamping plate 33. The grabbing component 41 can return to the film grabbing notch 35 again to grab the packaging film, and so on. There is no need for manual intervention.

[0035] Since the packaging film is relatively soft, it often bends and droops due to gravity, which can easily make it difficult for the mechanical structure to clamp it. However, the present invention can use the first clamping plate 32 and the second clamping plate 33 to clamp the packaging film located at the film-grabbing notch 35, so that the grasping component 41 can clamp the packaging film more easily, thereby improving the success rate of grasping the packaging film.

[0036] In some optional embodiments, at least two escape notches 34 are provided on each of the first and second clamping plates 32, 33. The escape notches 34 of the first and second clamping plates 32 and 33 are correspondingly connected to form a plurality of film-grabbing notches 35. The film conveying mechanism 40 includes at least two gripping assemblies 41 and at least two transfer assemblies 42. The transfer assemblies 42 are drivably connected to the gripping assemblies 41 to move the gripping assemblies 41 toward or away from the film-grabbing notches 35. Because the packaging film is relatively soft and often bends and droops due to gravity, the multiple gripping assemblies 41 grip different locations of the packaging film, allowing the film to remain stretched and straight after being pulled out, facilitating subsequent cutting, hot pressing, and other processes. This prevents wrinkles in the soft packaging film from affecting the hot pressing or cutting process. In this embodiment, two avoidance gaps 34 are provided on the first clamping plate 32 and the second clamping plate 33. The film conveying mechanism 40 includes two grabbing components 41 and two transfer components 42. The two grabbing components 41 grab the packaging film near its two sides.

[0037] The specific manner in which the first clamping plate 32 and the second clamping plate 33 are clamped and cooperated can be designed according to actual needs. For example, in some optional embodiments, the first clamping plate 32 is fixed to the base 10, and the second clamping plate 33 is rotatably connected to the base 10. The second clamping plate 33 is clamped and cooperated with the first clamping plate 32 under the drive of the power assembly 31. Of course, the first clamping plate 32 and / or the second clamping plate 33 can also be driven by the translation drive module to move closer to or farther away from each other to achieve the clamping and cooperation between the first clamping plate 32 and the second clamping plate 33. Alternatively, the first clamping plate 32 and / or the second clamping plate 33 are both driven by the power assembly 31 to move closer to or farther away from each other to achieve the clamping and cooperation.

[0038] See also Figure 4 In some optional embodiments, the power assembly 31 includes two push modules 311 and two connecting rods 312. The two push modules 311 are respectively arranged on either side of the second clamping plate 33. The ends of the connecting rods 312 are respectively connected to the telescopic end of the push module 311 and the side of the second clamping plate 33. Due to the large size of the pet mat, the packaging film is usually wide. Therefore, the width of the second clamping plate 33 needs to be designed to be wide. By driving on both sides of the second clamping plate 33, the second clamping plate 33 can apply uniform pressure to the first clamping plate 32, thereby stably clamping the packaging film. The push module 311 is rotatably coupled with the base 10, and the connection is rotatably coupled with the push module 311. Therefore, when the push module 311 drives the connecting rod 312 to rotate the second clamping plate 33, the push module 311 and the connecting rod 312 are less likely to cause structural interference.

[0039] The pushing module 311 can be a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, or the like.

[0040] In some optional embodiments, the film storage mechanism 20 includes a film storage roller 21 and a plurality of guide rollers 22. The film storage roller 21 is rotatably mounted on the base 10, and the guide rollers 22 are positioned between the film storage roller 21 and the first clamping plate 32. The film storage roller 21 is used to wind the packaging film, while the guide rollers 22 maintain tension on the packaging film to prevent wrinkles. The film storage roller 21 can actively unwind the packaging film driven by a motor. Alternatively, the film can be passively unwound by the film clamping mechanism 30 and the film conveying mechanism 40, as the film is pulled out by the film clamping mechanism 30 during conveyance.

[0041] In some optional embodiments, the film storage mechanism 20 also includes two pressing rollers 23, which are arranged side by side on the base 10. A film clamping channel is formed between the two pressing rollers 23. When the grabbing assembly 41 grabs the packaging film, the pressing rollers 23 cooperate to press the packaging film so that the packaging film can be tightened to avoid wrinkles in the packaging film, thereby facilitating the cutting operation.

[0042] In some optional embodiments, the film storage mechanism 20 further includes a pressing module 24, which is drivably connected to one of the pressing rollers 23 and is configured to drive one of the pressing rollers 23 toward the other. This drives one of the pressing rollers 23 to press against the other, enabling the two pressing rollers 23 to stably clamp the packaging film. The pressing module 24 can be implemented as a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0043] The specific structure of the gripping assembly 41 can be designed based on actual needs. For example, in some optional embodiments, the gripping assembly 41 includes a finger cylinder, and the transfer assembly 42 is driven and connected to the finger cylinder, and the finger cylinder is used to clamp the packaging film. Of course, the gripping assembly 41 can also adopt other structures, such as the gripping assembly 41 including two clamping parts that cooperate to clamp the packaging film.

[0044] The specific structure of the transfer assembly 42 can be designed according to actual needs. For example, in some optional embodiments, the transfer assembly 42 includes a guide rail 421, a motor 422, and a synchronous belt module 423. The guide rail 421 is arranged on one side of the base 10 and extends toward the film-grabbing notch 35. The gripping assembly 41 slides with the guide rail 421. The motor 422 is driven and connected to the gripping assembly 41 through the synchronous belt module 423 to drive the gripping assembly 41 to move along the guide rail 421. Of course, the transfer assembly 42 can also be a screw drive assembly, a rotary motor 422 translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor 422 translation drive assembly.

[0045] The aforementioned packaging film conveying device can be used in a pet mat packaging machine, which includes two packaging film conveying devices such as the aforementioned one. In this embodiment, the pet mat packaging machine further includes a conveying mechanism and a compression mechanism. The two packaging film conveying devices are disposed between the conveying mechanism and the compression mechanism. The two packaging film conveying devices pull the packaging film between the conveying mechanism and the compression mechanism. When the pet mat initially enters the conveying mechanism and is positioned between the packaging films grasped by the two packaging film conveying devices, the conveying mechanism conveys the pet mat to the compression mechanism while the two packaging film conveying devices simultaneously pull the packaging film. Subsequently, from top to bottom, the compression mechanism, packaging film, pet mat, packaging film, and conveying mechanism are arranged. The compression mechanism then compresses the pet mat, and then the packaging films above and below the pet mat are heat-pressed and sealed to achieve a sealed pet mat.

[0046] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
