DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1-Figure 4 , a shock-absorbing and damage-proof pizza fully-automatic loading plastic tray device shown in the figure includes a tray body 1, and also includes a buffer mechanism arranged on the tray body 1 for buffering the impact force of the pizza falling;

[0023] The buffer mechanism includes two sliding plates 201 symmetrically arranged and slidably connected in the tray body 1, a flexible mesh belt 202 is arranged between the two sliding plates 201, and a speed limiting mechanism for limiting the descending speed of the flexible mesh belt 202 is arranged on the tray body 1;

[0024] It should be noted here that: through the setting of the buffer mechanism, under the action of the speed limiting mechanism, three layers of buffering protection are provided for the impact force of the falling pizza, so that under the action of the three layers of buffering protection, the falling impact force of the pizza is buffered, reducing the impact force of the pizza on the tray body 1, thereby reducing the risk of damage to the pizza, and further improving the safety of the pizza packaging.

[0025] It is worth noting that the packaging structure of pancakes and its operating principle are prior arts and have been mastered by those skilled in the art, so no further elaboration is needed here.

[0026] See also Figure 3 The speed limiting mechanism shown in the figure includes four speed limiting tubes 301 fixedly connected to the bottom wall of the tray body 1 and arranged symmetrically in pairs, and the four speed limiting tubes 301 are slidably connected to the speed limiting rods 302, one end of the four speed limiting rods 302 is connected to the sliding plate 201, and one end of the four speed limiting rods 302 located inside the speed limiting tubes 301 is fixedly connected to the speed limiting plate 303, and the other side of the four speed limiting plates 303 is fixedly connected to the spring 304, and the other end of the four springs 304 is connected to the bottom wall of the speed limiting tube 301;

[0027] It should be noted here that: by setting the speed limiting mechanism, resistance is provided for the downward movement of the flexible mesh belt 202, thereby further buffering the impact force of the pancake.

[0028] See also Figure 3, the four speed limiting tubes 301 shown in the figure are filled with damping fluid, and four speed limiting holes 305 are opened on the four speed limiting plates 303, and the damping fluid passes through the four speed limiting holes 305;

[0029] It should be noted here that: when the speed limiting plate 303 slides in the speed limiting tube 301, the damping liquid in the speed limiting tube 301 will be squeezed. Since only four speed limiting holes 305 are provided on the speed limiting plate 303, the damping liquid can only pass through the four speed limiting holes 305, thereby forming a damping buffer mechanism, which further provides a third layer of buffering protection against the impact force of the falling pancake.

[0030] Working principle: When the pizzas are packed in boxes, the tray body 1 is conveyed to the pizza dropping area by the conveyor belt. When the tray body 1 is in the pizza dropping area, the packing mechanism is used to push an appropriate number of pizzas into the tray body 1. When the pizzas fall into the tray body 1, when the pizzas collide with the flexible mesh belt 202, the flexible mesh belt 202 provides a first layer of buffering for the falling of the pizzas.

[0031] At the same time, when the pancake falls onto the flexible mesh belt 202, the weight of the pancake will push the speed limiting plate 303 at one end of the speed limiting rod 302 to slide in the speed limiting tube 301, thereby squeezing the spring 304, causing the spring 304 to deform under force and form elastic force, thereby providing resistance to the descent of the flexible mesh belt 202 under the elastic force of the spring 304, and further providing a second layer of buffering protection against the falling impact of the pancake;

[0032] When the speed limiting plate 303 slides in the speed limiting tube 301, the damping liquid in the speed limiting tube 301 will be squeezed. Since only four speed limiting holes 305 are provided on the speed limiting plate 303, the damping liquid can only pass through the four speed limiting holes 305, thereby forming a damping buffer mechanism, which further provides a third layer of buffering protection for the impact force of the falling pizza. Under the action of the three layers of buffering protection, the falling impact force of the pizza is buffered, the impact force of the pizza on the tray body 1 is reduced, thereby reducing the risk of damage to the pizza, and further improving the safety of the pizza packaging.

[0033] Example 2

[0034] See also Figure 4 This embodiment further explains Example 1. The tray body 1 shown in the figure is provided with a limiting mechanism for limiting the position of the pancake. The limiting mechanism is a rubber airbag 4 arranged on two opposite inner walls of the tray body 1. The tray body 1 is provided with an air injection component for injecting air into the two rubber airbags 4.

[0035] It should be noted here that: through the setting of the limiting mechanism, under the action of the air injection assembly, the rubber airbag 4 will be inflated, and the inflated rubber airbag 4 will be against the pancake in the tray body 1, thereby performing flexible extrusion and limiting on the pancake, thereby improving the placement stability of the pancake in the tray body 1 and avoiding the pancake from being broken due to shaking. At the same time, when the pancake is placed on the surface of the flexible mesh belt 202, the rebound of the pancake is blocked by the limiting mechanism, thereby further improving the safety of the pancake falling into the tray body 1.

[0036] See also Figure 4 The gas injection assembly shown in the figure includes a gas injection pipe 501 fixedly connected to the bottom wall of the tray body 1, one end of the gas injection pipe 501 close to the rubber airbag 4 is fixedly connected to a connecting pipe 502, the other end of the connecting pipe 502 is set with a penetrating sliding plate 201 and connected to the rubber airbag 4, a gas injection plate 503 is slidably connected in the gas injection pipe 501, and a driving assembly for driving the gas injection plate 503 is provided on the gas injection pipe 501;

[0037] It should be noted here that: through the setting of the gas injection component, under the driving action of the driving component, the gas injection plate 503 will be pushed to move in the gas injection tube 501, so that under the squeezing action of the gas injection plate 503, the gas in the gas injection tube 501 is squeezed into the rubber airbag 4.

[0038] See also Figure 4 The driving assembly shown in the figure includes a driving rod 601 slidably connected to the gas injection pipe 501, one end of the driving rod 601 is connected to the gas injection plate 503, and the other end of the driving rod 601 is provided with an inclined surface 603 on the side wall, and the flexible mesh belt 202 is fixedly connected to the driving plate 602 on one side close to the gas injection pipe 501, and the other end of the driving plate 602 slides on the inclined surface 603;

[0039] It should be noted here that: through the setting of the driving assembly, when the flexible mesh belt 202 is squeezed by gravity, under the action of gravity, the driving plate 602 will be pushed to move close to the gas injection pipe 501, and when the driving plate 602 and the driving rod 601 are against each other, under the interaction force of the inclined surface 603, the gas injection plate 503 at one end of the driving rod 601 will be pushed to move in the gas injection pipe 501.
