Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a hot pressing device and a pet mat packaging machine. Background Art

[0002] With the improvement of people's living standards, most people will keep pets, such as cats, dogs, etc. In order to provide a more comfortable living environment for pets, people will buy pet mats. The pet mats are generally soft and elastic, and can provide a relatively comfortable resting and playing environment for pets.

[0003] Current pet mats usually consist of an outer cover and internal filling materials. The outer cover is mainly made of ice silk, cloth or velvet, and the internal filling materials are mainly cotton, wool, cloth, sponge, etc. According to the materials selected for the outer cover and internal filling materials, the pet mat can play a role in cooling or heat preservation. However, because the internal filling materials of the pet mat are often fluffy, the volume of the pet mat is too large and inconvenient for transportation. Therefore, the pet mat usually needs to be compressed and packaged to reduce its volume.

[0004] Currently, when compressing and packaging pet mats, usually the pet mat is first placed between the upper and lower packaging films, then compressed, and the rear sides of the upper and lower packaging films are hot pressed. Then it is transported to the next hot pressing mechanism to hot press the left and right sides of the upper and lower packaging films, and then transported to the next hot pressing mechanism to hot press the front sides of the upper and lower packaging films. Since the upper and lower packaging films are prone to wrinkles during the transportation of the pet mat, the thickness of the upper and lower packaging films at the hot pressing position is too thick, resulting in difficult heat transfer, so that the upper and lower packaging films cannot be completely melted and connected to each other to achieve sealing.

Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0035] Please refer to Figure 1 , an embodiment of the present utility model provides a hot pressing device, including: a frame 10, a pressing mechanism 20, a post-heat pressing mechanism 30, two side heat pressing mechanisms 40, and a front heat pressing mechanism 50.

[0036] Please refer to Figure 2 and Figure 3 , a pet mat support portion 11 and a hot pressing support portion 12 arranged around the support portion are provided on the frame 10; the pressing mechanism 20 includes a lower pressing seat 21 and a pressing driving assembly 22, and the lower pressing seat 21 moves along a direction close to or away from the pet mat support portion 11 under the drive of the pressing driving assembly 22.

[0037] The specific structure of the pressing driving assembly 22 can be designed according to actual needs. For example, the pressing driving assembly 22 can adopt a cylinder, a hydraulic cylinder, an electric cylinder, etc. The pressing driving assembly 22 is arranged on the frame 10, and its output shaft is drivingly connected to the lower pressing seat 21.

[0038] Please refer to Figure 4 and Figure 5, the post - hot - pressing mechanism 30 includes a post - hot - pressing block 31 and a post - hot - pressing driving assembly 32. The post - hot - pressing block 31 is arranged at the rear side of the lower pressing seat 21 and presses against or away from the post - hot - pressing area 121 of the hot - pressing support part 12 under the drive of the post - hot - pressing driving assembly. The side - hot - pressing mechanism 40 includes a side - hot - pressing block 41 and a side - hot - pressing driving assembly 42. The side - hot - pressing blocks 41 of the two side - hot - pressing mechanisms 40 are respectively arranged on the left and right sides of the lower pressing seat 21. The side - hot - pressing block 41 presses against or away from the side - hot - pressing area 122 of the hot - pressing support part 12 under the drive of the side - hot - pressing driving assembly. The side - hot - pressing area 122 is connected to the post - hot - pressing area 121, or a part of the side - hot - pressing area 122 overlaps with a part of the post - hot - pressing area 121. The front - hot - pressing mechanism 50 includes a front - hot - pressing block 51 and a front - hot - pressing driving assembly 52. The front - hot - pressing block 51 is arranged at the front side of the lower pressing seat 21. The front - hot - pressing block 51 presses against or away from the front - hot - pressing area 123 of the hot - pressing support part 12 under the drive of the front - hot - pressing driving assembly 52. The front - hot - pressing area 123 is connected to the side - hot - pressing area 122, or a part of the front - hot - pressing area 123 overlaps with a part of the side - hot - pressing area 122.

[0039] The post - hot - pressing block 31, the side - hot - pressing block 41 and the front - hot - pressing block 51 can increase their temperatures under the action of the heating device, so as to be able to hot - press the packaging film.

[0040] During hot - pressing, the lower packaging film is arranged on the pet - pad support part 11 and the hot - pressing support part 12. The pet pad 60 is arranged on the lower packaging film, and the upper packaging film is arranged on the pet pad 60. The lower pressing seat 21 presses down under the drive of the pressing - down driving assembly 22, so as to compress the pet pad 60. At this time, the upper packaging film also approaches the lower packaging film. Subsequently, the post - hot - pressing mechanism 30, the two side - hot - pressing mechanisms 40 and the front - hot - pressing mechanism 50 hot - press the upper and lower packaging films. The post - hot - pressing mechanism 30 fuses the parts of the upper and lower packaging films located in the post - hot - pressing area 121 together and generates a post - hot - pressing mark. The side - hot - pressing mechanism 40 fuses the parts of the upper and lower packaging films located in the side - hot - pressing area 122 together and generates a side - hot - pressing mark. The front - hot - pressing mechanism 50 fuses the parts of the upper and lower packaging films located in the front - hot - pressing area 123 together and generates a front - hot - pressing mark, so as to realize that the fused parts of the upper and lower packaging films are arranged around the pet pad 60. At this time, the upper and lower packaging films together form a packaging bag 61 for sealing the pet pad 60.

[0041] When the side - hot - pressing area 122 is connected to the post - hot - pressing area 121 and the front - hot - pressing area 123 is connected to the side - hot - pressing area 122, the post - hot - pressing block 31, the side - hot - pressing block 41 and the front - hot - pressing block 51 can be connected integrally and hot - press simultaneously. Of course, the post - hot - pressing block 31, the side - hot - pressing block 41 and the front - hot - pressing block 51 can also be hot - pressed in a suitable order.

[0042] 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, the front hot-pressing marks, side hot-pressing marks, and rear hot-pressing marks on the upper packaging film and the lower packaging film can overlap with each other, so that the sealing performance of the upper packaging film and the lower packaging film on the pet mat 60 is better and air leakage is not likely to occur. To achieve partial overlap of each hot-pressing area, there are various hot-pressing methods, for example:

[0043] The length of the side hot-pressing block 41 can be designed to be greater than the distance between the rear hot-pressing block 31 and the front hot-pressing block 51. During hot-pressing, first let the rear hot-pressing block 31 and the front hot-pressing block 51 press down directly, and then the two side hot-pressing blocks 41 move along the inclined downward direction gradually approaching the side hot-pressing area 122 to avoid collision between the side hot-pressing block 41 and the rear hot-pressing block 31 or the front hot-pressing block 51. Then, the side hot-pressing block 41 can press on the front hot-pressing area 123 and the rear hot-pressing area 121.

[0044] Or, similarly to the above hot-pressing method, the lengths of the rear hot-pressing block 31 and the front hot-pressing block 51 can be designed to be greater than the distance between the two side hot-pressing blocks 41. The two side hot-pressing blocks 41 press down directly, and the front hot-pressing block 51 moves along the inclined downward direction gradually approaching the front hot-pressing area 123 to avoid collision between the front hot-pressing block 51 and the side hot-pressing block 41, and the rear hot-pressing block 31 moves along the inclined downward direction gradually approaching the rear hot-pressing area 121 to avoid collision between the rear hot-pressing block 31 and the side hot-pressing block 41.

[0045] Or, the rear hot-pressing block 31, one of the side hot-pressing blocks 41, the front hot-pressing block 51, and the other side hot-pressing block 41 perform hot-pressing in sequence. The front hot-pressing block 51 moves along the inclined downward direction gradually approaching the front hot-pressing area 123, the rear hot-pressing block 31 moves along the inclined downward direction gradually approaching the rear hot-pressing area 121, and the side hot-pressing block 41 moves along the inclined downward direction gradually approaching the side hot-pressing area 122, so as to avoid collision between the rear hot-pressing block 31, the side hot-pressing block 41, and the front hot-pressing block 51.

[0046] Or, please refer to Figure 6, 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 41 is less than the distance between the rear hot pressing block 31 and the front hot pressing block 51, so that the side hot pressing block 41 can be arranged between the rear hot pressing block 31 and the front hot pressing block 51. The rear hot pressing block 31 and the two side hot pressing blocks 41 simultaneously perform hot pressing on the upper packaging film and the lower packaging film. The rear hot pressing block 31 hot presses the part of the upper packaging film and the lower packaging film located in the rear hot pressing area 121, while the two side hot pressing blocks 41 press on the part of the side hot pressing area 122 located outside the rear hot pressing area 121 and the part located within the front hot pressing area 123; subsequently, the side hot pressing block 41 and the rear hot pressing block 31 rise, and the rear hot pressing block 31 rises to a position higher than the side hot pressing block 41. Then, the two side hot pressing blocks 41 and the front hot pressing block 51 move towards the rear hot pressing area 121. At this time, a part of the side hot pressing block 41 can move to directly below the rear hot pressing block 31. Then, the two side hot pressing blocks 41 and the front hot pressing block 51 simultaneously press down. A part of the side hot pressing block 41 presses on the part of the side hot pressing area 122 located outside the front hot pressing area 123 and the part located within the rear hot pressing area 121, while the front hot pressing block 51 presses on 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.

[0047] In some alternative embodiments, the rear hot pressing drive assembly 32 includes a plurality of rear downward pressing drive modules. The rear downward pressing drive modules are arranged on the rear side of the downward pressing seat 21 and are drivingly connected to the rear hot pressing block 31, so as to drive the rear hot pressing block 31 to press the upper packaging film and the lower packaging film towards the hot pressing support portion 12.

[0048] In order to achieve Figure 6 the hot pressing method shown, in some alternative embodiments, the side hot pressing drive assembly 42 includes a plurality of side downward pressing drive modules 421, a side movable seat 422, and a side translation module 423. The side downward pressing drive modules 421 are arranged on the side movable seat 422 and are drivingly connected to the side hot pressing block 41. The side hot pressing block 41 presses towards the side hot pressing area 122 under the drive of the side downward pressing drive modules 421. The side movable seats 422 of the two side hot pressing drive assemblies 42 are respectively arranged on the left and right sides of the downward pressing seat 21. The side translation module 423 is drivingly connected to the side movable seat 422, and the side movable seat 422 moves in a direction close to or away from the rear hot pressing area 121 under the drive of the side translation module 423.

[0049] In order to achieve Figure 6In the hot pressing method shown, in some alternative embodiments, the front hot pressing drive assembly 52 includes a plurality of front downward pressing drive modules 521, a front movable seat 522, and a front translation module 523. The front downward pressing drive modules 521 are disposed on the front movable seat 522 and are drivingly connected to the front hot pressing block 51. The front hot pressing block 51 is pressed forward into the front hot pressing area 123 under the drive of the front downward pressing drive modules 521. The front movable seats 522 of the two front hot pressing drive assemblies 52 are respectively arranged on the front side of the downward pressing seat 21. The front translation module 523 is drivingly connected to the front movable seat 522, and the front movable seat 522 moves in a direction approaching or departing from the side hot pressing area 122 under the drive of the front translation module 523.

[0050] The specific structures of the rear downward pressing drive module, the side downward pressing drive module 421, the front downward pressing drive module 521, the side translation module 423, and the front translation module 523 can be designed according to actual needs. For example, the rear downward pressing drive module, the side downward pressing drive module 421, the front downward pressing drive module 521, the side translation module 423, or the front translation module 523 can adopt a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module. In this embodiment, the rear downward pressing drive module, the side downward pressing drive module 421, the front downward pressing drive module 521, the side translation module 423, and the front translation module 523 adopt cylinders.

[0051] In some alternative embodiments, a conveying mechanism 13 is provided on the frame 10. A pet pad support portion 11 is formed on the conveying mechanism 13. The conveying mechanism 13 facilitates conveying the pet pad 60 to directly below the downward pressing seat 21 and conveying the compressed and packaged pet pad 60 away.

[0052] Please refer to Figure 7 , in some alternative embodiments, the conveying mechanism 13 includes a conveying belt 131, a belt drive module 132, and a support plate 133. The conveying belt 131 is movably disposed on the frame 10 and moves cyclically under the drive of the belt drive module 132. The top of the portion of the conveying belt 131 extending between the hot pressing support portions 12 forms the pet pad support portion 11. The support plate 133 is disposed on the frame 10 and supports the bottom of the portion of the conveying belt 131 extending between the hot pressing support portions 12. When the downward pressing seat 21 compresses the pet pad 60, the support plate 133 can support the conveying belt 131. The conveying belt 131 itself has a certain elasticity, so the pressure generated by the downward pressing seat 21 is not likely to cause damage to the conveying belt 131.

[0053] In order to improve the accuracy of the pressing height of the pressing seat 21 and the stability of the movement of the pressing seat 21, in some alternative embodiments, the pressing mechanism 20 further includes a plurality of guiding racks 23 and a plurality of guiding gears 24. The guiding racks 23 are arranged on the frame 10, and the guiding gears 24 are rotatably arranged on the pressing seat 21 and are engaged with the guiding racks 23.

[0054] In some alternative embodiments, the pressing mechanism 20 further includes a plurality of guiding racks 23, a plurality of guiding gears 24 and a plurality of rotating rods 25. The plurality of guiding racks 23 are arranged around the pressing seat 21. The plurality of rotating rods 25 are rotatably arranged on the pressing seat 21 and are arranged around the pressing seat 21. Guiding gears 24 are respectively arranged at both ends of the rotating rod 25. The guiding of the pressing seat 21 by the plurality of guiding racks 23 makes it difficult for the pressing seat 21 to tilt relative to the pet pad support portion 11, so that the pressing seat 21 can stably compress the pet pad 60. The thickness of the compressed pet pad 60 is uniform, which is convenient for stacking the pet pads 60, avoiding uneven pressure exerted by the pressing seat 21 on the pet pad 60, and avoiding that part of the pet pad 60 cannot be completely compressed due to the tilt of the pressing seat 21.

[0055] The above-mentioned hot pressing device can be applied to a pet pad 60 packaging machine, and the pet pad 60 packaging machine includes: the above-mentioned hot pressing device.
