Description

Technical Field

[0001] The utility model relates to the technical field of packaging, and particularly relates to a compression packaging device for pet mats. Background Art

[0002] The pet mat is generally soft and elastic, and can provide a relatively comfortable rest and play environment for pets. The pet mat usually consists of an outer cover and internal filling. The outer cover is mainly made of ice silk, cloth or velvet, and the internal filling is mainly cotton, wool, cloth, sponge, etc. According to the materials selected for the outer cover and internal filling, the pet mat can play a role in cooling or heat preservation. Since the pet mat is often too large in volume, it needs to be compression-packaged.

[0003] At present, when compression-packaging a pet mat, it is necessary to initially heat-press the packaging film to form an open packaging bag, and then load the pet mat into the packaging bag and heat-press the packaging bag again for sealing. However, the packaging bag needs to be transported between the two heat-pressing operations, which easily causes wrinkles in the packaging bag during transportation, resulting in excessive thickness at the wrinkled position during subsequent heat-pressing and making it difficult to correctly heat-press and seal. It is necessary to repeat the heat-pressing multiple times, and the overall steps are relatively cumbersome due to the multiple heat-pressing operations before and after.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0061] Please refer to Figure 1 , an embodiment of the present utility model provides a compression packaging device for a pet mat, including: a frame 10, a transportation device 20, an upper packaging film conveying device 30, a lower packaging film conveying device 40, and a hot pressing device 50.

[0062] Please refer to Figure 1 and Figure 2 , a compression station 11 is preset on the rack 10; the transport device 20 is arranged on the rack 10 and extends to the compression station 11 for transporting the pet mat 70 into the compression station 11; the upper packaging film transport device 30 and the lower packaging film transport device 40 are arranged on the rack 10 and are located on one side of the compression station 11. The upper packaging film transport device 30 is used to transport the upper packaging film 80 to the top of the compression station 11, and the lower packaging film transport device 40 is used to transport the lower packaging film 90 along the transport direction of the transport device 20. After the transport device 20 transports the pet mat 70 until at least part of the pet mat 70 is located on the lower packaging film 90, the lower packaging film 90 moves along with the movement of the pet mat 70 to the inside of the compression station 11 along the transport device 20; the hot pressing device 50 is arranged above the compression station 11. The hot pressing device 50 is used to compress the pet mat 70 and perform hot pressing on the upper packaging film 80 and the lower packaging film 90 so that the upper packaging film 80 and the lower packaging film 90 jointly form a sealed pet mat packaging bag 71 for the pet mat 70.

[0063] Please refer to Figure 1 and Figure 2 , the process of packaging the pet mat 70 is described as follows:

[0064] The lower packaging film transport device 40 transports the lower packaging film 90 onto the transport device 20, and the pet mat 70 is placed on the transport device 20. When the transport device 20 transports the pet mat 70 until at least part of the pet mat 70 is located on the lower packaging film 90, a certain margin should be reserved between the front end of the lower packaging film 90 and the front side of the pet mat 70 for subsequent hot pressing.

[0065] Subsequently, the transport device 20 continues to transport, and the lower packaging film transport device 40 also drives the lower packaging film 90 to continue moving in the transport direction of the transport device 20 until the lower packaging film 90 and the pet mat 70 reach the compression station 11. Among them, since the pet mat 70 presses against the lower packaging film 90, at this time, the transport device 20 actually drives the pet mat 70 to transport through the lower packaging film 90. At this time, the transport speed of the lower packaging film 90 can be set to be not less than the transport speed of the transport device 20, so as to avoid the reduction of the margin of the lower packaging film 90 located in front of the pet mat 70. Of course, the optimal choice is that the transport speed of the lower packaging film 90 is set to be equal to the transport speed of the transport device 20, so as to avoid the lower packaging film 90 from loosening from the lower packaging film transport device 40 due to friction between the lower packaging film 90 and the transport device 20.

[0066] The conveying mode of the upper packaging film conveying device 30 for the upper packaging film 80 is relatively flexible. It only needs to convey the upper packaging film 80 to the compression station 11 between the compressed pet pads 70 so that the upper packaging film 80 is located above the pet pads 70. The design in this embodiment is to make the upper packaging film conveying device 30 operate synchronously with the lower packaging film conveying device 40.

[0067] When the upper packaging film 80, the pet pad 70, and the lower packaging film 90 all reach the compression station 11, at this time, the upper packaging film 80, the pet pad 70, and the lower packaging film 90 are arranged in sequence from top to bottom between the conveying device 20 and the hot pressing device 50. Subsequently, the hot pressing device 50 descends, pressing the upper packaging film 80, the pet pad 70, and the lower packaging film 90 against the conveying device 20, thereby realizing the compression of the pet pad 70. Subsequently, the upper packaging film 80 and the lower packaging film 90 are hot pressed by the hot pressing device 50, and the hot pressed parts of the upper packaging film 80 and the lower packaging film 90 will melt into one body to form hot pressing marks. The hot pressing marks are arranged around the pet pad 70, so that the pet pad 70 is sealed in a compressed state and cannot expand, achieving the effect of reducing the volume. Since the pet pad 70 can be immediately hot pressed and sealed after compression, the upper packaging film 80 and the lower packaging film 90 will not be subjected to other transfer processes that cause wrinkles, thus avoiding the situation where the heat cannot be well transferred during hot pressing due to excessive thickness at the wrinkled position, resulting in the upper packaging film 80 not being able to be melted into one body with the lower packaging film 90. While improving the success rate of sealed packaging, it also improves the packaging efficiency.

[0068] In order to achieve continuous packaging production, and the upper packaging film 80 and the lower packaging film 90 are usually stored in rolls. After the upper packaging film 80 and the lower packaging film 90 form a sealed packaging bag 71, it is necessary to cut between the packaging bag 71 and the unused upper packaging film 80 and lower packaging film 90 to facilitate the next packaging. The cutting process can be carried out after the pet pad 70 is compressed, or during or after the hot pressing. The cutting can be done manually or automatically by a mechanical structure. In this embodiment, a cutting device 510 is used for automatic cutting. The cutting device 510 is arranged on one side of the compression station 11 facing the upper packaging film conveying device 30 or the lower packaging film conveying device 40, and the cutting device 510 is used to cut the upper packaging film 80 and the lower packaging film 90.

[0069] Please refer to Figures 3 to 7 In some alternative embodiments, the hot pressing device 50 includes a pressing mechanism 520, a post - hot pressing mechanism 530, two side - hot pressing mechanisms 540, and a front - hot pressing mechanism 550.

[0070] A pet pad support part 21 located within the compression station 11 is provided on the conveying device 20, and a hot pressing support part 12 arranged around the support part is provided on the frame 10.

[0071] The pressing mechanism 520 includes a lower pressing seat 521 and a pressing drive assembly 522. The lower pressing seat 521 approaches or moves away from the pet mat support portion 21 under the drive of the pressing drive assembly 522. The specific structure of the pressing drive assembly 522 can be designed according to actual needs. For example, the pressing drive assembly 522 can adopt a cylinder, a hydraulic cylinder, an electric cylinder, etc. The pressing drive assembly 522 is arranged on the frame 10, and its output shaft is drivingly connected to the lower pressing seat 521.

[0072] The post-heat pressing mechanism 530 includes a post-heat pressing block 531 and a post-heat pressing drive assembly 532. The post-heat pressing block 531 is arranged at the rear side of the lower pressing seat 521 and presses against or moves away from the post-heat pressing area 121 of the heat pressing support portion 12 under the drive of the post-heat pressing drive assembly. The side heat pressing mechanism 540 includes a side heat pressing block 541 and a side heat pressing drive assembly 542. The side heat pressing blocks 541 of the two side heat pressing mechanisms 540 are respectively arranged on the left and right sides of the lower pressing seat 521. The side heat pressing block 541 presses against or moves away from the side heat pressing area 122 of the heat pressing support portion 12 under the drive of the side heat pressing drive assembly. The side heat pressing area 122 is connected to the post-heat pressing area 121, or a part of the side heat pressing area 122 overlaps with a part of the post-heat pressing area 121. The front heat pressing mechanism 550 includes a front heat pressing block 551 and a front heat pressing drive assembly 552. The front heat pressing block 551 is arranged at the front side of the lower pressing seat 521. The front heat pressing block 551 presses against or moves away from the front heat pressing area 123 of the heat pressing support portion 12 under the drive of the front heat pressing drive assembly 552. The front heat pressing area 123 is connected to the side heat pressing area 122, or a part of the front heat pressing area 123 overlaps with a part of the side heat pressing area 122.

[0073] The post-heat pressing block 531, the side heat pressing block 541, and the front heat pressing block 551 can increase their temperatures under the action of the heating device, so as to be able to perform heat pressing on the upper packaging film 80 and the lower packaging film 90.

[0074] During hot pressing, the lower packaging film 90 is arranged on the pet mat support part 21 and the hot pressing support part 12. The pet mat 70 is arranged on the lower packaging film 90, and the upper packaging film 80 is arranged on the pet mat 70. The lower pressing seat 521 is pressed down by the driving of the pressing drive assembly 522, so as to compress the pet mat 70. At this time, the upper packaging film 80 also approaches the lower packaging film 90. Subsequently, the rear hot pressing mechanism 530, the two side hot pressing mechanisms 540 and the front hot pressing mechanism 550 perform hot pressing on the upper packaging film 80 and the lower packaging film 90. The rear hot pressing mechanism 530 fuses the parts of the upper packaging film 80 and the lower packaging film 90 located in the rear hot pressing area 121 together and generates a rear hot pressing mark. The side hot pressing mechanism 540 fuses the parts of the upper packaging film 80 and the lower packaging film 90 located in the side hot pressing area 122 together and generates a side hot pressing mark. The front hot pressing mechanism 550 fuses the parts of the upper packaging film 80 and the lower packaging film 90 located in the front hot pressing area 123 together and generates a front hot pressing mark, so that the parts where the upper packaging film 80 and the lower packaging film 90 are fused together are arranged around the pet mat 70. At this time, the upper packaging film 80 and the lower packaging film 90 together form a packaging bag 71 for sealing the pet mat 70.

[0075] When the side hot pressing area 122 is connected to the rear hot pressing area 121 and the front hot pressing area 123 is connected to the side hot pressing area 122, the rear hot pressing block 531, the side hot pressing block 541 and the front hot pressing block 551 can be connected integrally and perform hot pressing simultaneously. Of course, the rear hot pressing block 531, the side hot pressing block 541 and the front hot pressing block 551 can also perform hot pressing in a suitable order.

[0076] When a part of the side hot pressing area 122 overlaps with a part of the rear hot pressing area 121 and a part of the front hot pressing area 123 overlaps with a part of the side hot pressing area 122, it can make the front hot pressing mark, the side hot pressing mark and the rear hot pressing mark on the upper packaging film 80 and the lower packaging film 90 overlap with each other, so that the sealing performance of the upper packaging film 80 and the lower packaging film 90 on the pet mat 70 is better and it is not easy to leak air. In order to achieve the partial overlap of each hot pressing area, there are various hot pressing methods to achieve it. For example:

[0077] The length of the side hot pressing block 541 can be designed to be greater than the distance between the rear hot pressing block 531 and the front hot pressing block 551. During hot pressing, first let the rear hot pressing block 531 and the front hot pressing block 551 press down directly, and then the two side hot pressing blocks 541 move along the inclined downward direction gradually approaching the side hot pressing area 122 to avoid collision between the side hot pressing block 541 and the rear hot pressing block 531 or the front hot pressing block 551. Then the side hot pressing block 541 can be pressed on the front hot pressing area 123 and the rear hot pressing area 121.

[0078] Alternatively, similar to the above hot pressing method, the lengths of the rear hot pressing block 531 and the front hot pressing block 551 can be designed to be greater than the distance between the two side hot pressing blocks 541. The two side hot pressing blocks 541 press down directly, while the front hot pressing block 551 moves along an inclined downward direction gradually approaching the front hot pressing area 123 to avoid collision between the front hot pressing block 551 and the side hot pressing blocks 541, and the rear hot pressing block 531 moves along an inclined downward direction gradually approaching the rear hot pressing area 121 to avoid collision between the rear hot pressing block 531 and the side hot pressing blocks 541.

[0079] Alternatively, the rear hot pressing block 531, one of the side hot pressing blocks 541, the front hot pressing block 551, and the other side hot pressing block 541 perform hot pressing in sequence. The front hot pressing block 551 moves along an inclined downward direction gradually approaching the front hot pressing area 123, the rear hot pressing block 531 moves along an inclined downward direction gradually approaching the rear hot pressing area 121, and the side hot pressing block 541 moves along an inclined downward direction gradually approaching the side hot pressing area 122, so as to avoid collision between the rear hot pressing block 531, the side hot pressing blocks 541, and the front hot pressing block 551.

[0080] Alternatively, please refer to Figure 8 , in this embodiment, a preset hot pressing method is adopted. The preset hot pressing method is as follows: the length of the side hot pressing block 541 is less than the distance between the rear hot pressing block 531 and the front hot pressing block 551, so that the side hot pressing block 541 can be arranged between the rear hot pressing block 531 and the front hot pressing block 551. The rear hot pressing block 531 and the two side hot pressing blocks 541 simultaneously press the upper packaging film 80 and the lower packaging film 90. The rear hot pressing block 531 presses the parts of the upper packaging film 80 and the lower packaging film 90 located in the rear hot pressing area 121, while the two side hot pressing blocks 541 press the parts of the side hot pressing area 122 located outside the rear hot pressing area 121 and inside the front hot pressing area 123; then the side hot pressing blocks 541 and the rear hot pressing block 531 rise, and the rear hot pressing block 531 rises to a position higher than the side hot pressing blocks 541. Then the two side hot pressing blocks 541 and the front hot pressing block 551 move towards the rear hot pressing area 121. At this time, a part of the side hot pressing block 541 can move to directly below the rear hot pressing block 531. Then the two side hot pressing blocks 541 and the front hot pressing block 551 press down simultaneously. A part of the side hot pressing block 541 presses the parts of the side hot pressing area 122 located outside the front hot pressing area 123 and inside the rear hot pressing area 121, while the front hot pressing block 551 presses the front hot pressing area 123. Of course, it is not limited to the above hot pressing method, and those skilled in the art can also select other suitable hot pressing methods according to the teachings of the present invention.

[0081] In some alternative embodiments, the rear hot pressing driving assembly 532 includes a plurality of rear pressing driving modules. The rear pressing driving modules are arranged at the rear side of the pressing seat 521 and are drivingly connected to the rear hot pressing block 531, so as to drive the rear hot pressing block 531 to press the upper packaging film 80 and the lower packaging film 90 towards the hot pressing support part 12.

[0082] To implement the preset hot pressing method in this embodiment, the side hot pressing drive assembly 542 includes a plurality of side downward pressing drive modules 5421, a side movable seat 5422, and a side translation module 5423. The side downward pressing drive modules 5421 are arranged on the side movable seat 5422 and are drivingly connected to the side hot pressing block 541. The side hot pressing block 541 is pressed towards the side hot pressing area 122 under the drive of the side downward pressing drive module 5421. The side movable seats 5422 of the two side hot pressing drive assemblies 542 are respectively arranged on the left and right sides of the downward pressing seat 521. The side translation module 5423 is drivingly connected to the side movable seat 5422, and the side movable seat 5422 moves in a direction close to or away from the rear hot pressing area 121 under the drive of the side translation module 5423; the front hot pressing drive assembly 552 includes a plurality of front downward pressing drive modules 5521, a front movable seat 5522, and a front translation module 5523. The front downward pressing drive modules 5521 are arranged on the front movable seat 5522 and are drivingly connected to the front hot pressing block 551. The front hot pressing block 551 is pressed towards the front hot pressing area 123 under the drive of the front downward pressing drive module 5521. The front movable seats 5522 of the two front hot pressing drive assemblies 552 are respectively arranged on the front side of the downward pressing seat 521. The front translation module 5523 is drivingly connected to the front movable seat 5522, and the front movable seat 5522 moves in a direction close to or away from the side hot pressing area 122 under the drive of the front translation module 5523. Of course, with the above structures, the rear hot pressing drive assembly 532, the side hot pressing drive assembly 542, and the front hot pressing drive assembly 552 can also cooperate to implement other hot pressing methods.

[0083] The specific structures of the rear downward pressing drive module, the side downward pressing drive module 5421, the front downward pressing drive module 5521, the side translation module 5423, and the front translation module 5523 can be designed according to actual needs. For example, the rear downward pressing drive module, the side downward pressing drive module 5421, the front downward pressing drive module 5521, the side translation module 5423, or the front translation module 5523 can adopt a lead screw drive module, a rotary motor 3422 translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor 3422 translation drive module. In this embodiment, the rear downward pressing drive module, the side downward pressing drive module 5421, the front downward pressing drive module 5521, the side translation module 5423, and the front translation module 5523 adopt cylinders.

[0084] In some alternative embodiments, the transport device 20 includes a support transport mechanism 22 and a transition transport mechanism 23. The support transport mechanism 22 is disposed in the compression station 11, and a pet mat support portion 21 is formed on the support transport mechanism 22. The hot pressing support portion 12 is arranged around the support transport mechanism 22. The transition transport mechanism 23 is disposed on one side of the compression station 11 and extends towards the support transport mechanism 22. The lower packaging film conveying device 40 conveys the lower packaging film 90 from between the support transport mechanism 22 and the transition transport mechanism 23 onto the support transport mechanism 22. When the transition transport mechanism 23 conveys the pet mat 70 until at least a part of the pet mat 70 is on the lower packaging film 90 located on the support transport mechanism 22, the lower packaging film 90 moves along with the movement of the pet mat 70 onto the support transport mechanism 22 and into the compression station 11.

[0085] During the process of conveying the pet mat 70 to the compression station 11, the lower packaging film conveying device 40 conveys the lower packaging film 90 onto the support transport mechanism 22, while the pet mat 70 is placed on the transition transport mechanism 23. When the transition transport mechanism 23 conveys the pet mat 70 until at least a part of the pet mat 70 is on the lower packaging film 90 located on the support transport mechanism 22, a certain margin should be reserved between the front end of the lower packaging film 90 and the front side of the pet mat 70 for subsequent hot pressing.

[0086] Subsequently, the transition transport mechanism 23 continues to convey, the support transport mechanism 22 starts, and the lower packaging film conveying device 40 also drives the lower packaging film 90 to continue moving along the conveying direction of the support transport mechanism 22 until the lower packaging film 90 and the pet mat 70 reach the compression station 11. Among them, since the pet mat 70 presses against the lower packaging film 90, at this time, the support transport mechanism 22 actually drives the pet mat 70 to transport through the lower packaging film 90. At this time, the conveying speed of the lower packaging film 90 can be set to be not less than the conveying speed of the support transport mechanism 22, so as to avoid the reduction of the margin of the lower packaging film 90 in front of the pet mat 70. Of course, the optimal choice is to set the conveying speed of the lower packaging film 90 to be equal to the conveying speed of the support transport mechanism 22, so as to avoid the lower packaging film 90 rubbing against the transport device 20 and causing the lower packaging film 90 to come off from the lower packaging film conveying device 40. In addition, the conveying speed of the transition transport mechanism 23 can be set to be not greater than the conveying speed of the support transport mechanism 22, so as to avoid the front side of the pet mat 70 approaching the front end of the lower packaging film 90 during the process of the pet mat 70 being transported from the transition transport mechanism 23 to the support transport mechanism 22 due to the conveying speed of the transition transport mechanism 23 being faster than the conveying speed of the lower packaging film 90 and the speed of the support transport mechanism 22, resulting in the reduction of the margin of the lower packaging film 90 in front of the pet mat 70 and making it impossible to perform subsequent hot pressing operations.

[0087] Please refer to Figure 9, in some alternative embodiments, the support and transport mechanism 22 includes a conveyor belt 221, a belt drive module 222, and a support plate 223. The conveyor belt 221 is movably disposed on the frame 10 and circulates under the drive of the belt drive module 222. A pet mat support portion 21 is formed on the top of the portion of the conveyor belt 221 extending between the hot pressing support portions 12. The support plate 223 is disposed on the frame 10 and supports the bottom of the portion of the conveyor belt 221 extending between the hot pressing support portions 12. When the pressing seat 521 compresses the pet mat 70, the support plate 223 can support the conveyor belt 221. The conveyor belt 221 itself has a certain elasticity, so the pressure generated by the pressing seat 521 is not likely to cause damage to the conveyor belt 221.

[0088] Please refer to Figures 3 to 5 , the cutting method of the cutting device 510 can be selected according to actual needs. It can be achieved by moving along the surfaces of the upper packaging film 80 and the lower packaging film 90, or by punching with a cutting knife 511 wider than the widths of the upper packaging film 80 and the lower packaging film 90. For the convenience of implementing cutting, in this embodiment, the cutting device 510 includes a cutting knife 511 and a punching assembly 512. The punching assembly 512 is connected to the post-hot pressing block 531. The cutting knife 511 is disposed on the side of the post-hot pressing block 531 away from the compression station 11. The punching assembly 512 is used to drive the cutting knife 511 to move towards the lower packaging film 90 and the upper packaging film 80. After the post-hot pressing drive assembly 532 drives the post-hot pressing block 531 to press against the upper packaging film 80 and the lower packaging film 90, the punching assembly 512 and the cutting knife 511 also move closer to the upper packaging film 80 and the lower packaging film 90. At this time, since the post-hot pressing block 531 has already pressed the upper packaging film 80 and the lower packaging film 90 tightly, the punching assembly 512 can drive the cutting knife 511 to move towards the upper packaging film 80 and the lower packaging film 90, and the cutting knife 511 will complete the cutting of the upper packaging film 80 and the lower packaging film 90. Of course, the cutting device 510 can also be disposed on the frame 10 and below the lower packaging film 90 to perform punching cutting or cutting from left to right on the upper packaging film 80 and the lower packaging film from bottom to top.

[0089] Please refer to Figure 10 and Figure 11 , in some alternative embodiments, both the upper packaging film conveying device 30 and the lower packaging film conveying device 40 include a base 310, a film storage mechanism 320, a film clamping mechanism 330, and a film conveying mechanism 340. The base 310, the film storage mechanism 320, the film clamping mechanism 330, and the film conveying mechanism 340 of the upper packaging film conveying device 30 are similar in structure to those of the lower packaging film conveying device 40. Therefore, only the upper packaging film conveying device 30 is illustrated.

[0090] The base 310 is arranged on the frame 10, and the film storage mechanism 320 is arranged on the base 310 for unwinding the packaging film; the film clamping mechanism 330 is arranged on the base 310, which includes a power component 331, a first clamping plate 332 and a second clamping plate 333. The first clamping plate 332 and the second clamping plate 333 are arranged on the base 310 and are located on one side of the film storage mechanism 320. The first clamping plate 332 and the second clamping plate 333 are clamped and cooperated under the drive of the power component 331. Two avoiding notches 334 are arranged on both the first clamping plate 332 and the second clamping plate 333. When the first clamping plate 332 and the second clamping plate 333 are clamped and cooperated, the avoiding notch 334 of the first clamping plate 332 and the avoiding notch 334 of the second clamping plate 333 correspond to form a film grasping notch 335 together; the film conveying mechanism 340 includes two grasping components 341 and two transferring components 342. The two transferring components 342 are respectively arranged on both sides of the compression station 11. The transferring component 342 is drivingly connected to the grasping component 341 for driving the grasping component 341 to approach or move away from the film grasping notch 335. When the grasping component 341 is driven by the transferring component 342 to correspondingly extend into the film grasping notch 335, the grasping component 341 clamps the lower packaging film 90 or the upper packaging film 80 located in the film grasping notch 335. Subsequently, the transferring component 342 can drive the grasping component 341 to move. In this embodiment, the transferring component 342 of the upper packaging film conveying device 30 drives the grasping component 341 to the side of the compression station 11 away from the film clamping mechanism 330, so that the upper packaging film 80 passes through the compression station 11 and can cover the top of the pet mat 70 located in the compression station 11. The transferring component 342 of the lower packaging film conveying device 40 drives the grasping component 341 to the side of the compression station 11 away from the film clamping mechanism 330, so that the lower packaging film 90 passes through the compression station 11 and can cover the bottom of the pet mat 70 located in the compression station 11.

[0091] The packaging film stored on the film storage mechanism 320 extends between the first clamping plate 332 and the second clamping plate 333. A part of the packaging film is exposed to the film grasping notch 335. The grasping component 341 extends into the film grasping notch 335 and grabs the lower packaging film 90 or the upper packaging film 80. Subsequently, the transferring component 342 drives the grasping component 341 to move away from the film grasping notch 335 so that the packaging film is pulled out.

[0092] After the pulled-out packaging film is cut, at this time, the uncut packaging film still remains between the first clamping plate 332 and the second clamping plate 333. The grasping component 341 can return to the film grasping notch 335 again to grab the lower packaging film 90 or the upper packaging film 80. In this way, it reciprocates without manual participation in pulling and fixing the packaging film.

[0093] Since the packaging film is relatively soft itself, it often bends and droops due to gravity, which easily causes the mechanical structure to be difficult to clamp. However, the present utility model can adopt the clamping of the first clamping plate 332 and the second clamping plate 333, so that the packaging film located at the film-grabbing notch 335 remains taut, and the grabbing assembly 341 can more easily clamp the packaging film, improving the success rate of grabbing the packaging film. In addition, by grabbing both sides of the packaging film with the two grabbing assemblies 341, the packaging film can maintain an unfolded and taut state after being pulled out, facilitating subsequent processes such as cutting and hot pressing, and avoiding wrinkles on the packaging film due to its softness, which may affect the hot pressing or cutting processes.

[0094] Please refer to Figure 12 and Figure 13 , the specific manner of the clamping cooperation between the first clamping plate 332 and the second clamping plate 333 can be designed according to actual needs. For example, in some alternative embodiments, the first clamping plate 332 is fixed on the base 310, the second clamping plate 333 is rotatably connected to the base 310, and the second clamping plate 333 is driven by the power assembly 331 to cooperate with the first clamping plate 332 for clamping. Of course, the first clamping plate 332 and / or the second clamping plate 333 can also be driven by a translation driving module to approach or move away from each other to achieve the clamping cooperation between the first clamping plate 332 and the second clamping plate 333. Alternatively, both the first clamping plate 332 and / or the second clamping plate 333 are driven by the power assembly 331 to approach or move away from each other to achieve the clamping cooperation.

[0095] After the film conveying mechanism 340 of the upper packaging film conveying device 30 conveys the upper packaging film 80 to the compression station 11, at this time, the clamping mechanism 330 of the upper packaging film conveying device 30 and the gripping assembly 341 of the film conveying mechanism 340 are located on opposite sides of the compression station 11, the lower pressing seat 521 is located between the clamping mechanism 330 and the gripping assembly 341 of the film conveying mechanism 340, and the two fulcrums of the upper packaging film 80 are located on the clamping mechanism 330 and the gripping assembly 341; because the pet mat 70 itself is relatively large in volume and has a certain height, during the compression of the pet mat 70, the part of the upper packaging film 80 located in the compression station 11 is also pressed down by the lower pressing seat 521 and thus descends. If the positions of the clamping mechanism 330 and the gripping assembly 341 of the upper packaging film conveying device 30 remain unchanged at this time, the upper packaging film 80 will be pulled by the lower pressing seat 521, resulting in a decrease in the thickness of the upper packaging film 80 and even causing the upper packaging film 80 to break. Therefore, in some alternative embodiments, the upper packaging film conveying device 30 further includes a lifting mechanism 35. The base 310 of the upper packaging film conveying device 30 is liftably arranged on one side of the lower pressing seat 521 through the lifting mechanism 35. The two transfer assemblies 342 of the upper packaging film conveying device 30 are respectively arranged on both sides of the lower pressing seat 521. When the lower pressing seat 521 descends to press the upper packaging film 80, the pet mat 70, and the lower packaging film 90 against the pet mat support portion 21, the base 310 of the upper packaging film conveying device 30 is driven by the lifting mechanism 35 to descend synchronously with the lower pressing seat 521, thereby causing the clamping mechanism 330 of the upper packaging film conveying device 30 to also descend synchronously with the lower pressing seat 521. The transfer assemblies 342 of the upper packaging film conveying device 30 are installed on the lower pressing seat 521 and move along with the lower pressing seat 521, so that the gripping assembly 341 connected to the transfer assemblies 342 also moves along with the lower pressing seat 521. Therefore, when the lower pressing seat 521 presses down the upper packaging film 80, the pet mat 70, and the lower packaging film 90, the upper packaging film 80 also descends synchronously with the lower pressing seat 521, avoiding the phenomenon that the upper packaging film 80 is pulled and damaged or its thickness is reduced.

[0096] Of course, in order to avoid the upper packaging film 80 from being pulled, the clamping of the upper packaging film 80 by the clamping mechanism 330 can also be released, so that the upper packaging film 80 stored when the lower pressing seat 521 descends is driven out by the lower pressing seat 521 to adapt to the movement of the lower pressing seat 521. This is not limited to this example.

[0097] The specific clamping and matching manner of the first clamping plate 332 and the second clamping plate 333 can be designed according to actual needs. For example, in some alternative embodiments, the first clamping plate 332 is fixed on the base 310, the second clamping plate 333 is rotatably connected to the base 310, and the second clamping plate 333 is driven by the power assembly 331 to clamp and match with the first clamping plate 332. Of course, the first clamping plate 332 and / or the second clamping plate 333 can also be driven by a translation driving module to approach or move away from each other, so as to realize the clamping and matching between the first clamping plate 332 and the second clamping plate 333. Or, both the first clamping plate 332 and / or the second clamping plate 333 are driven by the power assembly 331 to approach or move away from each other to realize the clamping and matching.

[0098] In some alternative embodiments, the power assembly 331 includes two pushing modules 311 and two connecting rods 312. The two pushing modules 311 are respectively arranged on both sides of the second clamping plate 333. The two ends of the connecting rod 312 are respectively connected to the telescopic end of the pushing module 311 and the side part of the second clamping plate 333. Since the pet mat 70 is relatively large in volume and the width of the packaging film is usually wide, the width of the second clamping plate 333 also needs to be designed wider. By driving on both sides of the second clamping plate 333, the second clamping plate 333 can apply uniform pressure to the first clamping plate 332, so as to stably clamp the packaging film. The pushing module 311 is rotatably matched with the base 310, and the connecting rod is rotatably matched with the pushing module 311. Therefore, when the pushing module 311 drives the connecting rod 312 to push the second clamping plate 333 to rotate, it is not easy for the pushing module 311 to drive the connecting rod 312 to generate structural interference.

[0099] The pushing module 311 can be a cylinder, an electric cylinder, an oil cylinder, etc.

[0100] In some alternative embodiments, the film storage mechanism 320 includes a film storage roller 321 and several guide rollers 322. The film storage roller 321 is rotatably arranged on the base 310, and the guide rollers 322 are arranged between the film storage roller 321 and the first clamping plate 332. The film storage roller 321 is used for winding the packaging film, and the guide rollers 322 can tighten the packaging film to prevent the packaging film from wrinkling. The film storage roller 321 can actively unwind the packaging film driven by a motor. Of course, it can also not actively unwind, but when the film clamping mechanism 330 and the film conveying mechanism 340 cooperate to convey the packaging film, the packaging film is passively unwound due to being pulled out by the film clamping mechanism 330.

[0101] In some alternative embodiments, the film storage mechanism 320 further includes two pressure rollers 323. The two pressure rollers 323 are arranged side by side on the base 310, and a film clamping channel is formed between the two pressure rollers 323. When the grabbing assembly 341 grabs the packaging film, the pressure rollers 323 cooperate to press the packaging film tightly, so that the packaging film can be tightened to prevent the packaging film from wrinkling, which is beneficial to the cutting operation.

[0102] In some alternative embodiments, the film storage mechanism 320 further includes a pressing module 324. The pressing module 324 is drivingly connected to one of the pressure rollers 323 and is configured to drive one of the pressure rollers 323 to press against the other pressure roller 323. By driving one of the pressure rollers 323 to press against the other, the two pressure rollers 323 can stably clamp the packaging film. The pressing module 324 can be a cylinder, an electric cylinder, a hydraulic cylinder, or the like.

[0103] The specific structure of the grasping assembly 341 can be designed according to actual needs. For example, in some alternative embodiments, the grasping assembly 341 includes a finger cylinder. The transfer assembly 342 is drivingly connected to the finger cylinder, and the finger cylinder is used to grip the packaging film. Of course, the grasping assembly 341 can also adopt other structures. For example, the grasping assembly 341 includes two clamping parts that cooperate to grip the packaging film.

[0104] The specific structure of the transfer assembly 342 can be designed according to actual needs. For example, in some alternative embodiments, the transfer assembly 342 includes a guide rail 3421, a motor 3422, and a synchronous belt module 3423. The guide rail 3421 is arranged on the side of the compression station 11 and extends toward the film grasping notch 335. The grasping assembly 341 is slidably engaged with the guide rail 3421. The motor 3422 is drivingly connected to the grasping assembly 341 through the synchronous belt module 3423 and is configured to drive the grasping assembly 341 to move along the guide rail 3421. Of course, the transfer assembly 342 can also be a lead screw drive assembly, a rotary motor 3422 translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor 3422 translation drive assembly.

[0105] Please refer to Figure 14 and Figure 15, in some alternative embodiments, the compression packaging device for the pet mat further includes a pet mat centering device 60; the pet mat centering device 60 includes a conveying mechanism 610, a centering driving device 620 and two centering plates 630; the conveying mechanism 610 is arranged on the frame 10 and is connected to the transportation device 20, the centering driving device 620 is arranged on the frame 10 and is drivingly connected to the two centering plates 630, the two centering plates 630 are respectively arranged on both sides of the conveying path of the conveying mechanism 610, and the two centering plates 630 move synchronously away from or towards each other under the drive of the centering drive, so as to clamp the pet mat 70 at a predetermined position, then the two centering plates 630 move away from each other under the drive of the centering drive and disengage from the pet mat 70, and then the conveying mechanism 610 conveys the pet mat 70 to the transportation device 20. In this embodiment, the conveying mechanism 610 conveys the pet mat 70 to the transition transportation mechanism 23. The predetermined position can be the middle position of the transition transportation mechanism 23 or other suitable positions. Since the staff only needs to place the pet mat 70 on the conveying mechanism 610, or the production equipment directly feeds the pet mat 70 onto the conveying mechanism 610, and then the position can be adjusted by the centering plates 630, which saves time and effort. Moreover, the two centering plates 630 move synchronously, which can make the positioning position of the pet mat 70 more accurate.

[0106] Please refer to Figure 16 and Figure 17 , the specific structure of the centering driving device 620 can be designed according to actual needs. For example, in some alternative embodiments, the centering driving device 620 includes a driving motor 621, a transmission gear 622 and two transmission racks 623. The driving motor 621 is arranged on the frame 10 and is drivingly connected to the transmission gear 622. The two transmission racks 623 are respectively arranged on both sides of the transmission gear 622 and are meshed with the transmission gear 622. The transmission racks 623 are correspondingly connected to the centering plates 630. When the driving motor 621 drives the transmission gear 622 to rotate, the transmission gear 622 drives the two transmission racks 623 to move synchronously away from or towards each other, and further drives the centering plates 630 to move synchronously away from or towards each other through the transmission racks 623. The cooperation of the transmission gear 622 and the transmission racks 623 can more accurately control the moving position of the centering plates 630. Of course, the centering driving device 620 can also adopt two translation driving modules, and the translation driving modules are correspondingly drivingly connected to the centering plates 630. The translation driving modules can be screw driving modules, rotary motor 3422 translation driving modules, belt translation driving modules, cylinder translation driving modules or linear motor 3422 translation driving modules.

[0107] The specific structure of the conveying mechanism 610 can be designed according to actual needs. For example, in some alternative embodiments, the conveying mechanism 610 includes a conveying power module 611 and a plurality of conveying rollers 612. The conveying rollers 612 are rotationally engaged with the frame 10. The plurality of conveying rollers 612 are arranged in sequence along the conveying path of the conveying mechanism 610. The conveying power module 611 is drivingly connected to the conveying rollers 612. The centering plate 630 is located above the conveying rollers 612. The conveying power module 611 can adopt a conveying power motor to drive a toothed chain to move. A gear meshing with the toothed chain is provided on the side of the conveying roller 612. The toothed chain drives the gear to rotate, thereby realizing the rotation of the conveying roller 612. When the conveying roller 612 rotates, it can drive the pet pad 70 to move. Of course, the conveying power motor of the conveying power module 611 can also be meshed with the gear of the conveying roller 612 through a plurality of gear sets to achieve transmission. Alternatively, the conveying power module 611 can also adopt a plurality of conveying power motors, and the output shaft of the conveying power motor is directly drivingly connected to the conveying roller 612. In addition, the conveying mechanism 610 is not limited to the form of the conveying roller 612. The conveying mechanism 610 can also adopt a belt conveying mechanism 610, a chain plate conveying mechanism 610, etc., and this is not limited to this example.

[0108] In order to simplify the structure of the overall pet pad centering device 60 and improve the aesthetic appearance, in some alternative embodiments, a plurality of slide rails 13 are provided on the frame 10, and two sliding seats 14 slidably engaged with the slide rails 13. The transmission rack 623 is connected to the sliding seat 14. The slide rails 13 and the sliding seats 14 are arranged below the conveying rollers 612. A plurality of connecting rods 141 are provided on the sliding seat 14. The connecting rods 141 pass through the gaps between adjacent two conveying rollers 612 and are then connected to the centering plate 630. The sliding seat 14 and the slide rails 13 can improve the stability of the movement of the centering plate 630. By utilizing the certain gaps existing between adjacent conveying rollers 612, the sliding seat 14 and the slide rails 13 can be arranged below the conveying mechanism 610, thereby hiding structures such as the sliding seat 14 and the slide rails 13, making the overall device look neater and more beautiful.

[0109] In this embodiment, for the convenience of installation, transportation, and position adjustment of each transportation device 20, upper packaging film conveying device 30, lower packaging film conveying device 40, and hot pressing device 50, the frame 10 is divided into a first bracket, a second bracket, and a third bracket arranged in sequence. The pet mat centering device 60 is arranged on the first bracket. The transition transportation mechanism 23, the lifting mechanism 35 of the upper packaging film conveying device 30, the base 310 of the upper packaging film conveying device 30, the film storage mechanism 320 of the upper packaging film conveying device 30, the film clamping mechanism 330 of the upper packaging film conveying device 30, the base 310 of the lower packaging film conveying device 40, the film storage mechanism 320 of the lower packaging film conveying device 40, and the film clamping mechanism 330 of the lower packaging film conveying device 40 are arranged on the second bracket. The support transportation mechanism 22, the hot pressing device 50, the film conveying mechanism 340 of the upper packaging film conveying device 30, and the film conveying mechanism 340 of the lower packaging film conveying device 40 are arranged on the third bracket.

[0110] In addition, due to the limitation of the hot pressing support portion 12, the support transportation mechanism 22 may not be able to completely convey the packaged pet mat 70 away from the compression station 11. For the convenience of discharging the packaged pet mat 70 after packaging, a discharging transportation mechanism 24 is also provided on one side of the frame. The discharging transportation mechanism 24 is connected to the end position of the support transportation mechanism 22. The discharging transportation mechanism 24 and the end position of the support transportation mechanism 22 can be directly connected or separated by a certain distance. Some of the packaged pet mats 70 that are partially separated from the compression station 11 abut against the discharging transportation mechanism 24 and are thus driven by the discharging transportation mechanism to leave the compression station 11.

[0111] The specific structures of the transition transportation mechanism 23 and the discharging transportation mechanism 24 can be designed according to actual needs. For example, the transition transportation mechanism 23 and the discharging transportation mechanism 24 can be a mesh belt and chain transportation mechanism, a roller and wheel transportation mechanism, a chain plate transportation mechanism, or a belt transportation mechanism.

[0112] 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 principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
