[0001] This utility model relates to the field of composite bubble film production technology, and in particular to a limitable composite bubble film cutting device. Background Technology

[0002] With the continuous development of the bubble wrap industry, the market for composite bubble wrap is also expanding. Composite bubble wrap is usually made of multiple materials. This composite structure makes it perform better in terms of moisture resistance, waterproofing, and pressure resistance, and can play a better role in protecting the packaged goods. During the production process of composite bubble wrap, it needs to be cut.

[0003] To address this, patent CN212795081U discloses a bubble wrap cutting device, comprising a cutting device body, an upper structure, and a lower structure, with a partition between them. The lower structure has a first part, a second part, and a third part, while the upper structure has a fourth part, a fifth part, and a sixth part. The lower part of the cutting device body has support feet with rubber pads at their bottoms. The fourth part has a bubble wrap roller, and the fifth part has a cutting system and a transmission system. The cutting system includes a cutting blade, a blade holder, and a cutting table. The transmission system includes a motor, a drive wheel, a driven wheel, a belt, and a transmission platform. The blade holder has a circular groove and an internal thread. The blade connects to the internal thread on the blade holder via a bottom thread. The upper part of the blade holder has a dovetail block connected to the circular groove on the upper part of the blade holder. This invention improves the cutting efficiency of bubble wrap by incorporating a cutting system and a transmission system.

[0004] When using existing composite bubble wrap cutting devices, the waste composite bubble wrap tends to stick to the cutting blade, making it difficult to clean and affecting the cutting efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a limitable composite bubble film cutting device to solve the problem that existing limitable composite bubble film cutting devices have difficulty cleaning the composite bubble film waste adhering to the cutting blade.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a limitable composite bubble film cutting device, including a cutting frame, on which a cutting assembly is installed. The cutting assembly consists of a driving cylinder, a lifting frame installed at the output end of the driving cylinder, a knife holder installed at the bottom end of the lifting frame, and a cutting blade installed on the knife holder. Cleaning structures are provided on both sides of the cutting blade. The cleaning structure includes a bracket symmetrically installed at the bottom end of the lifting frame, a limiting groove opened in the bracket, a limiting spring installed inside the limiting groove, a connecting block connected to the limiting spring, a push plate fixedly connected to the connecting block, an adjusting screw installed on the push plate, a bushing connected to the adjusting screw, and a scraper fixedly connected to the bushing. A pressing structure is provided on one side of the bottom end of the lifting frame. A cutting table is installed at the bottom end inside the cutting frame. A limiting structure is provided on the cutting table. A limiting roller is installed on one side of the cutting frame, and a composite bubble film unwinding roller is installed on one side of the limiting roller.

[0007] Preferably, the limiting structure includes a fixing hole, a screw, and a limiting rod. The limiting rods are symmetrically installed on both ends of the cutting table, and a screw is installed at the bottom end of each limiting rod. The upper surface of the cutting table has a fixing hole that cooperates with the screw.

[0008] The above structure can limit the movement of the composite bubble film and prevent it from shifting during cutting.

[0009] Preferably, there are several fixing holes, which are arranged at equal intervals on both sides of the upper surface of the cutting table.

[0010] The above structure allows for adjustment of the position of the limiting rod, enabling the limiting of composite bubble films of different widths.

[0011] Preferably, one end of the adjusting screw is inserted into the bushing and forms a sliding connection therewith.

[0012] The above structure allows for adjustment of the scraper's position, ensuring it makes full contact with the cutting table.

[0013] Preferably, the width of the scraper is the same as the width of the cutting blade.

[0014] The above structure allows for thorough cleaning of the cutting blade, improving cleaning efficiency.

[0015] Preferably, the clamping structure includes a fixed frame, a pressure plate, a positioning groove, and a telescopic spring. The fixed frame is installed on one side of the bottom end of the lifting frame. The fixed frame has a positioning groove inside, and a telescopic spring is installed inside the positioning groove. The pressure plate is installed at the bottom end of the telescopic spring.

[0016] The above structure allows the composite bubble film to be compressed during cutting, preventing it from shifting.

[0017] Preferably, the pressure plate and the telescopic spring form a telescopic structure.

[0018] The above structure reduces the impact force on the composite bubble film when the pressure plate moves downward, thus providing a certain degree of protection for the composite bubble film.

[0019] The present invention provides a limiting composite bubble film cutting device, the advantages of which are:

[0020] The limiting structure can limit the composite bubble film of different widths. When the cutting component operates and the lifting frame moves down, the pressing structure can press the composite bubble film. When the cutting component returns, the cleaning structure can push the composite bubble film away from the cutting blade to avoid the composite bubble film sticking to the cutting blade. On the other hand, it can clean the composite bubble film waste stuck to the cutting blade.

[0021] With the cleaning structure in place, when the cutting blade moves upward, the push plate moves away from the limit rod. The limit spring acts on the push plate to move downward, giving the composite bubble film a downward force to move it away from the cutting blade, thus preventing the composite bubble film from sticking to the cutting blade. At the same time, the scraper can clean up the composite bubble film waste stuck to the cutting blade, improving cutting efficiency.

[0022] By setting a limiting structure, the screw can be screwed into the fixing holes at different positions to adjust the position of the limiting rod, so that it can limit the composite bubble film of different widths and prevent the composite bubble film from shifting during cutting.

[0023] With the set clamping structure, when the cutting component is in operation, the lifting frame moves down, which in turn moves the fixed frame down, and the pressure plate comes into contact with the composite bubble film to achieve the purpose of clamping it, so as to prevent the composite bubble film from moving during cutting. The telescopic spring can reduce the impact force on the composite bubble film when the pressure plate moves down. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5 The present invention provides a limiting composite bubble film cutting device, including a cutting frame 3.

[0032] Reference Figures 1-5 As shown, the cutting frame 3 is equipped with a cutting assembly 7, which consists of a drive cylinder 71, a lifting frame 72 installed at the output end of the drive cylinder 71, a blade holder 74 installed at the bottom end of the lifting frame 72, and a cutting blade 73 installed on the blade holder 74.

[0033] Cleaning structures 6 are provided on both sides of the cutting blade 73. The cleaning structures 6 are used to clean the composite bubble film waste adhering to the cutting blade 73. The cleaning structure 6 includes a bracket 61 symmetrically installed at the bottom of the lifting frame 72, a limiting groove 67 opened in the bracket 61, a limiting spring 68 installed in the limiting groove 67, a connecting block 66 connected to the limiting spring 68, a push plate 63 fixedly connected to the connecting block 66, an adjusting screw 62 installed on the push plate 63, a bushing 64 connected to the adjusting screw 62, one end of the adjusting screw 62 is inserted into the bushing 64 and forms a sliding connection with it, and a scraper 65 fixedly connected to the bushing 64. The width of the scraper 65 is the same as the width of the cutting blade 73.

[0034] A cutting table 4 is installed at the bottom of the cutting frame 3. A limiting structure 5 is provided on the cutting table 4. The limiting structure 5 is used to limit the position of the composite bubble film. The limiting structure 5 includes a fixing hole 51, a screw 52 and a limiting rod 53. The limiting rod 53 is symmetrically installed on both ends of the cutting table 4. A screw 52 is installed at the bottom of each limiting rod 53. The upper surface of the cutting table 4 is provided with fixing holes 51 that cooperate with the screw 52. There are several fixing holes 51, which are arranged at equal intervals on both sides of the upper surface of the cutting table 4. A limiting roller 2 is installed on one side of the cutting frame 3, and a composite bubble film unwinding roller 1 is installed on one side of the limiting roller 2.

[0035] The composite bubble film is unwound by the unwinding roller 1 and limited by the limiting roller 2. Based on the width of the composite bubble film, the screw 52 is screwed into the appropriate fixing hole 51, and the limiting rod 53 is installed. The limiting rod 53 limits the composite bubble film to prevent it from shifting during cutting. Rotating the adjusting screw 62 causes the bushing 64 to move the scraper 65, bringing it into contact with the cutting blade 73. Activating the drive cylinder 71 causes the lifting frame 72 to move the cutting blade 73 downwards, and the limiting rod 53 pushes the push plate 63. The blade moves upward, exposing the cutting blade 73, which cuts the composite bubble film on the cutting table 4. After cutting, the drive cylinder 71 is turned off, and the lifting frame 72 drives the cutting blade 73 to move upward. The push plate 63 moves away from the limit rod 53, and the limit spring 68 causes the push plate 63 to move downward, giving the composite bubble film a downward force to move it away from the cutting blade 73, thus preventing the composite bubble film from sticking to the cutting blade 73. At the same time, the scraper 65 can clean up the composite bubble film waste stuck to the cutting blade 73, improving the cutting efficiency.

[0036] Reference Figure 1 , Figure 2 and Figure 3 As shown, a pressing structure 8 is provided on one side of the bottom end of the lifting frame 72. The pressing structure 8 is used to press the composite bubble film during cutting. The pressing structure 8 includes a fixed frame 81, a pressure plate 82, a positioning groove 83, and a telescopic spring 84. The fixed frame 81 is installed on one side of the bottom end of the lifting frame 72. The positioning groove 83 is opened inside the fixed frame 81, and the telescopic spring 84 is installed inside the positioning groove 83. The pressure plate 82 is installed at the bottom end of the telescopic spring 84. The pressure plate 82 and the telescopic spring 84 constitute a telescopic structure.

[0037] When the cutting assembly 7 is in operation and the lifting frame 72 moves down, the fixing frame 81 moves down, and the pressure plate 82 comes into contact with the composite bubble film and presses it down to prevent the composite bubble film from moving during cutting. The telescopic spring 84 can reduce the impact force on the composite bubble film when the pressure plate 82 moves down.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
