Description

Technical Field

[0001] The utility model belongs to the technical field of cushioning packaging production, and in particular relates to a gourd film automatic material cutting and blowing component. Background Art

[0002] The modern logistics environment is produced along with the development of the global economy. Packaging, as the starting point of the entire circulation link, has a great impact on other variables in the modern circulation environment, such as transportation costs, storage and transportation costs, packaging material costs, and the subsequent recycling rate of packaging materials. As an important part of the logistics process, the rationality of packaging design directly determines the subsequent process of logistics. Due to the rise of e-commerce, modern logistics will transport more and more fragile items, such as fresh products, eggs, fruits and other foods, for long-distance logistics, or mobile phones, tablets, desktop computers and other precision devices after packaging. These logistics transport items need to be cushioned and packaged to avoid deformation and damage caused by squeezing and bumping during transportation.

[0003] For example, a gourd film with high structural strength disclosed in publication number CN213650567U is a transparent film made of high molecular polyethylene material. Due to the characteristics of plastic products, it can be properly stretched, and then the product can be wrapped and packaged to achieve 360-degree all-round protection without dead angles. Compared with traditional logistics buffer filling materials, the gourd film will not cause the product to shift and cause damage during transportation due to the large space in the packaging box. Even if it encounters external pressure extrusion, the process level of the gourd film will disperse the pressure to the whole body to prevent the product from being damaged, which greatly increases the buffer protection effect during transportation and reduces the damage rate of the product to a minimum. In the process of preparing the gourd film, it is inflated by a matching inflation device, and then the whole film will become a protective material composed of multiple bubbles. Because the bubbles are shaped like a gourd, the gourd film is named. There are tearable dotted lines on the gourd film, which can be torn according to the size of the protected product when used, without waste.

[0004] However, the prior art lacks an equipment component that can simultaneously discharge material, blow air to form bubbles, and wind and roll the prepared gourd film to complete the finished product during the preparation process of the gourd film. Utility Model Content

[0029] 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.

[0030] like Figure 1-Figure 2 As shown, the utility model is a gourd film automatic material cutting and blowing assembly, the assembly includes a first fixed shaft 1 and a second fixed shaft 2, the first fixed shaft 1 is provided with a first pressing roller 11, the second fixed shaft 2 is provided with a second pressing roller 21, the first pressing roller 11 is provided with a first reel-changing shaft 3 in a direction obliquely above the first fixed shaft 1;

[0031] The first fixed shaft 1 is connected to the first nip roller 11 via a first fixed component; the second fixed shaft 2 is connected to the second nip roller 21 via a second fixed component;

[0032] The assembly further includes a material cutting assembly 7 arranged on the second fixed assembly, the assembly further includes a film lifting roller 5 arranged obliquely above the material cutting assembly 7, and a second reel changing shaft 6 arranged obliquely below and in front of the film lifting roller 5, and the cylindrical outer walls of the first reel changing shaft 3 and the second reel changing shaft 6 are respectively sleeved with replaceable first paper tubes 31 and second paper tubes 61; the film lifting roller 5 is fixed by a lifting roller fixed shaft, and the lifting roller fixed shaft is fixed to the equipment by a fixing plate, and the lifting roller fixed shaft can be driven by a driving motor to rotate around its own axis in its original position;

[0033] The assembly further comprises an air blowing pipe 8 arranged on the second fixing assembly, and a plurality of air blowing holes facing the gourd membrane are evenly spaced at the lower end of the air blowing pipe 8;

[0034] The cutting assembly 7 is used to cut the gourd film wound between the first pressing arm 11, the first paper tube 31, the second pressing roller 21, the mold lifting roller 5 and the second paper tube 61. The first fixed shaft 1 and the second fixed shaft 2 are fixed in space by a fixing plate, and the two are not connected to the driving motor and will not rotate relative to the first fixed assembly and the second fixed assembly at their positions.

[0035] Specifically, Figure 2 Observe the automatic material cutting and blowing assembly of the gourd film from the right side perspective. During the production of the gourd film, the initial end of the original plastic film required for the production of the gourd film is first stretched from above the first fixed axis to below the first pressing roller 11, and then counterclockwise from front to back around the circular outer surface of the first pressing roller 11 to the lower side of 31, and then clockwise from back to front to the upper side of 31 and stretched to the lower surface of the second pressing roller 22, and pulled upward to the vicinity of 5, and stretched from the rear side of 5 along the circular outer surface of 5 to its uppermost end and continued to stretch clockwise to its front side, and then stretched to the front side of the circular outer surface of the second paper tube 61.

[0036] like Figure 3 As shown, the first fixed component includes first fixed arms 12 arranged at the left and right ends of the first fixed axis 1, a first pressing axis 13 fixedly connected to the front ends of the two first fixed arms 12, and the first pressing roller 11 is sleeved on the cylindrical outer surface of the first pressing roller 13, and can rotate around the first pressing axis 13 as the gourd film is continuously fed and moved.

[0037] like Figure 3 As shown, the second fixed assembly includes second fixed arms 22 arranged at the left and right ends of the second fixed shaft 2, a second pressing shaft 23 fixedly connected to the front ends of the two second fixed arms 22, and the second pressing roller 21 is sleeved on the cylindrical outer surface of the second pressing shaft 23, and can rotate around the second pressing shaft 23 as the gourd film is continuously fed and moved.

[0038] By setting the first fixing component and the second fixing component, the first pressing roller 11 and the second pressing roller 21 can form a fixed spatial position on the front side of the entire component, which is convenient for laying the raw material plastic film for producing gourd film and subsequent blowing and cutting.

[0039] like Figure 4 As shown, in order to complete the integrated production of material laying, material blowing and material cutting in the gourd film production process, the material cutting component 7 includes a support plate 71 arranged at the upper part between the two second fixed arms 22 of the second fixed component, an L-shaped fixed plate 72 arranged on the support plate 71, two knife-breaking connecting rods 73 are sleeved at both ends of the L-shaped fixed plate 72, an electric telescopic rod 74 is fixed in the middle of the L-shaped fixed plate 72, and the telescopic direction of the electric telescopic rod 74 is the front-to-back direction, and the two knife-breaking connecting rods 73 are parallel to the electric telescopic rod 74 and are axially symmetrically arranged on the fixed plate 72 about the electric telescopic rod 74;

[0040] The front ends of the two knife-breaking connecting rods 73 and the electric telescopic rod 74 are both fixed with the same knife-breaking fixing block 75 , on which a knife-breaking fixing block 75 is fixed, and the front end of the knife-breaking 76 has sharp teeth 761 for cutting the gourd film. Figure 4

[0041] The initial position of the broken knife 76 is at the rear side of the second nip roller 22. Figure 2 The position state of the broken knife 76 when the broken knife cuts the gourd film is shown. Initially, the broken knife 76 is at the rear side of the vertical plane where the second nip roller 22 is located, thereby ensuring that the sharp teeth 761 will not touch the gourd film stretched between the second nip roller 22 and the film lifting roller 5. When it is necessary to cut the gourd film that has been blown and hot-pressed and sealed, the electric telescopic rod 74 is controlled to extend forward, thereby driving the sharp teeth 761 to touch the gourd film stretched between the second nip roller 22 and the film lifting roller 5, and the gourd film can be cut here;

[0042] Then control the first reel-changing shaft 3 and the second reel-changing shaft 6 to rotate, complete the winding of the gourd film before and after the cutting, and automatically complete the material collection. The original film material that has not been blown is collected at the first paper tube 31. When it is necessary to continue blowing to complete the production of the gourd film with bubble capsules, the initial end of the plastic film required for the original production of the gourd film is stretched and fixed at the circumferential surface position of the second paper tube 61 again according to the above-mentioned winding method.

[0043] like Figure 2 , Figure 4As shown, two knife-breaking connecting rods 73 and electric telescopic rods 74 are equally spaced and fixed in the vertical section of the L-shaped fixing plate 72. The knife-breaking connecting rod 73 passes through and is positioned in the vertical section of the L-shaped fixing plate 72 through a gasket 731 and a sleeve 732 arranged at the front side and the rear side of the vertical section of the L-shaped fixing plate 72. The vertical section of the L-shaped fixing plate 72 is close to the direction of the second pressing shaft 23, and the horizontal section of the L-shaped fixing plate 72 is fixed on the support plate 71. The two second fixing arms 22 of the second fixing assembly are arranged with the rear side higher than the front side and tilted 20° to 35° from the rear to the front.

[0044] By providing a gasket 731 on the front side of the vertical section of the L-shaped fixing plate 72 and a shaft sleeve 732 on the rear side, and passing the corresponding knife-breaking connecting rod 73 through the L-shaped fixing plate 72 from back to front, and being sleeved on the left end or the right end of the vertical section of the L-shaped fixing plate 72, when the electric telescopic rod 74 is started and retracted, the left or right knife-breaking connecting rod 73 is driven to retract forward and backward, and slide forward and backward at the fixed position on the left end or the right end of the L-shaped fixing plate 72, thereby driving the two knife-breaking connecting rods 73 and the electric telescopic rod 74 to move forward and backward with the knife-breaking fixing block 75 fixed on their front side and the knife-breaking 76 fixed thereon. The lateral end of the L-shaped fixing plate 72 is fixed on the support plate 71, and can be obliquely fixed above the second fixing component with the rear side higher and the front side lower, so as to be required. When the gourd film is to be cut, the electric telescopic rod 74, which is also obliquely arranged on the vertical section of the L-shaped fixed plate 72, can be started, and the knife-breaking connecting rods 73 on both sides can be driven to move synchronously, so that the knife-breaking can be evenly stressed, and move back and forth in a parallel state with the second pressing roller 21, the film lifting roller 5 and other multiple rollers or paper tubes wrapped with plastic films, so as to perform parallel cutting on the gourd film with bubble capsules that has been blown; the defect of non-parallel cutting lines caused by the uneven force caused by only setting an electric telescopic rod 74 at the transverse midpoint of the knife-breaking 76 is avoided, so that the finished products rolled up by the second paper tube 61 are all finished products with vertical cutting and the whole piece of gourd film being rectangular or square, thereby ensuring the yield of gourd film production.

[0045] The working principle of the automatic material cutting and blowing component of the gourd film provided by the utility model is:

[0046] First, the material is laid according to the winding direction of the original plastic film produced by the gourd film; the driving motor of the first nip roller 11, the second nip roller 21, the film lifting roller 5 and the second material changing shaft 6 is started, and the first nip roller 11 and the second nip roller 21 are controlled to rotate counterclockwise, and the film lifting roller 5 and the second material changing shaft 6 are controlled to rotate clockwise, and at the same time, the air blowing pipe 8 is controlled to open, and air is blown to the plastic film between the first paper tube 3 and the second nip roller 221 through the air blowing hole, so that the plastic film gradually passes through the first paper tube 3 and the second nip roller 21 to form a bubble capsule here, and the second nip roller 22 can be set as a heating tube with a self-heating function or a heat transfer function, or a heat sealing component is set outside the second nip roller 22, and the heat sealing component can be an electric heating tube or an electric heat sealing component driven by an electric intermittent feeding structure, so as to complete the heat sealing at the second nip roller 21 but will not cause the gourd film to break after heat sealing;

[0047] The first nip roller 11 and the second nip roller 21 rotate counterclockwise, and the film lifting roller 5 and the second material changing shaft 6 rotate clockwise to accelerate the initial section of the plastic film to continuously advance and stretch the plastic film behind to advance, and complete the blowing between the first paper tube 3 and the second nip roller 21 to form a bubble bag and heat seal at the second nip roller 23;

[0048] When the second paper roll 61 has been wound with the required length of the finished gourd film and needs to be cut, the electric telescopic rod 74 is controlled to start and extend, and at the same time, the driving motor for driving the second reel-changing shaft 3 to rotate is turned on, and the second reel-changing shaft 3 is controlled to rotate clockwise, thereby completing the cutting of the gourd film at the position between the second pressing roller 21 and the film lifting roller 5. At this time, the second reel-changing shaft 6 continues to rotate clockwise to complete the winding of the cut gourd film. At the same time, the second reel-changing shaft 3 drives the second paper tube 31 to rotate clockwise to complete the recovery of the remaining plastic film used as the raw material for the production of the gourd film, and all of them are wound up on the surface of the second paper roll 31, which is convenient for the subsequent direct loading and use of raw materials.
