Description

Technical Field

[0001] The utility model relates to the technical field of pulp molding, in particular to a pulp molding buffer paper tray for packaging. Background Art

[0002] Pulp molding is an environmentally friendly packaging material, mainly used for various consumer and industrial purposes. It uses waste paper as raw material and is made into paper products of various shapes through processes such as pulping, adsorption molding, drying and shaping. It has the characteristics of being environmentally friendly, recyclable, and having good cushioning and protective properties.

[0003] However, the applicant found that when transporting high-precision electronic devices, the vibration generated by the vehicle during driving will cause the electronic devices to move downward. When the downward force generated by the bumps on the electronic devices is large enough, the bottom of the electronic devices can easily collide with the pulp molded box, which can easily cause damage to the electronic devices and affect the accuracy of use. For this reason, we propose a pulp molded cushioning paper tray for packaging. Utility Model Content

[0004] The purpose of the utility model is to provide a pulp molded cushioning paper tray for packaging, so as to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a pulp molded cushioning paper tray for packaging, comprising: a paperboard, on which paper tubes are uniformly and integrally formed, and reinforcing ribs are connected between adjacent paper tubes;

[0006] The inner wall of the paper tube is fitted with a buffer tube, which is made of rubber.

[0007] The outer wall of the buffer tube is in contact with the inner wall of the paper tube, and the top of the buffer tube is in contact with the top of the paper tube and the cardboard;

[0008] A buffer assembly is provided at the bottom of the buffer cylinder;

[0009] The top of the paperboard is connected to the pressing plate at all four sides, the bottom of the pressing plate is fitted and connected to the buffer cylinder, and through holes corresponding to the buffer cylinder are evenly opened on the pressing plate.

[0010] As a preferred solution of the pulp molded buffer paper tray for packaging described in the utility model, the diameter of the through hole is larger than the diameter of the inside of the buffer tube.

[0011] As a preferred solution of the pulp molded buffer paper tray for packaging described in the utility model, the buffer component includes a connecting plate, and air bags are evenly arranged on the bottom of the connecting plate.

[0012] As a preferred solution of the pulp molded buffer paper tray for packaging described in the utility model, the top of the connecting plate is bonded to the buffer cylinder.

[0013] As a preferred solution of the pulp molded cushioning paper tray for packaging described in the utility model, the air bag is in a columnar structure, and the bottom of the air bag is in close contact with the bottom inner wall of the paper tube.

[0014] As a preferred solution of the pulp molded buffer paper tray for packaging described in the utility model, wherein: mounting plates are bonded to the four sides of the top of the paperboard, a screw penetrating the pressure plate is provided on the top of the mounting plate, and a nut is screwed on the screw.

[0015] As a preferred solution of the pulp molded cushioning paper tray for packaging described in the utility model, the bottom of the nut is fitted with a gasket fitted on the top of the pressing plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. A rubber buffer tube is placed inside the paper tube, and a cylindrical airbag is arranged at the bottom of the buffer tube. When the downward force generated by the bumps is large enough after the high-precision electronic device is placed in the buffer tube, the bottom of the electronic device collides with the buffer tube, and the buffer tube can first cushion the impact. When the bottom of the buffer tube is squeezed, the connecting plate drives the airbag to compress, which can further cushion the impact, thereby improving the cushioning capacity of the pulp molding and better protecting the packaged high-precision electronic devices.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] As mentioned in the background, in the prior art, when transporting high-precision electronic devices, the vibrations generated by the vehicle during travel can cause the electronic devices to move downward. When the downward force generated by the bumps is large enough, the bottom of the electronic device can easily collide with the pulp molded box, causing damage to the electronic device and affecting its usability. The present utility model provides a pulp molded cushioning paper tray for packaging.

[0024] Example 1

[0025] Reference Figures 1 to 2 A pulp molded cushioning paper tray for packaging, comprising a paperboard 1, a paper tube 2 uniformly and integrally formed on the paperboard 1, and reinforcing ribs 3 connecting adjacent paper tubes 2;

[0026] The inner wall of the paper tube 2 is fitted with a buffer tube 4, which is made of rubber.

[0027] The outer wall of the buffer tube 4 fits with the inner wall of the paper tube 2, and the top of the buffer tube 4 fits and connects to the top of the paper tube 2 and the cardboard 1, so that it can be easily inserted into the paper tube 2 and then put on the top of the cardboard 1;

[0028] A buffer assembly is provided at the bottom of the buffer cylinder 4;

[0029] The top of the cardboard 1 is connected to the pressing plate 5 all around, and the bottom of the pressing plate 5 is fitly connected to the buffer tube 4. The pressing plate 5 can uniformly press each buffer tube 4 for easy fixation, and the pressing plate 5 is evenly provided with through holes 6 opposite to the buffer tube 4, which does not affect the installation of electronic devices.

[0030] The diameter of the through hole 6 is larger than the inner diameter of the buffer cylinder 4 , so that the electronic device does not contact the through hole 6 .

[0031] The buffer assembly includes a connecting plate 7, and air bags 8 are evenly arranged on the bottom of the connecting plate 7. In order to facilitate connection, the top of the connecting plate 7 is bonded to the buffer tube 4. The air bag 8 is a columnar structure, and the bottom of the air bag 8 is connected to the bottom inner wall of the paper tube 2. The buffer tube 4 is placed in the paper tube 2, so that the air bag 8 is attached to the bottom inner wall of the paper tube 2, and then the high-precision electronic device is placed in the buffer tube 4. When the downward force generated by the bump is large enough, the bottom of the electronic device collides with the buffer tube 4, and can be buffered by the buffer tube 4 first. When the bottom of the buffer tube 4 is squeezed, the connecting plate 7 drives the air bag 8 to be compressed, which can further buffer, improve the buffering capacity of the pulp molding, and better protect the packaged high-precision electronic devices.

[0032] Mounting plates 9 are bonded to the top of the cardboard 1 all around. A screw 10 is provided on the top of the mounting plate 9, which passes through the pressure plate 5, and a nut 11 is screwed on the screw 10. The pressure plate 5 is put on each screw 10, and then the nut 11 is rotated to press the pressure plate 5 down on the top of the buffer tube 4 to fix the buffer tube 4.

[0033] Example 2

[0034] Reference Figures 1 to 2 In order to improve the stability during fixation, a gasket is attached to the top of the pressure plate 5 and is connected to the bottom of the nut 11. The gasket increases the friction between the nut 11 and the pressure plate 5, thereby improving stability.

[0035] The rest of the structure is the same as that of Example 1.

[0036] 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.
