Description

Technical Field

[0001] This application relates to the field of film technology, and in particular to a double-layer film pressing and molding device for food packaging bag processing. Background Technology

[0002] Film is a thin, soft, transparent sheet made of plastics, adhesives, rubber, or other materials. Scientifically, it is explained as a two-dimensional material formed by the deposition of atoms, molecules, or ions on the surface of a substrate. These include low-density polyethylene (LDPE) film, high-density polyethylene (HDPE) film, and linear low-density polyethylene (LLDPE) film. These films are flexible and transparent, with good water resistance and moisture resistance, and are widely used in general moisture-proof packaging and frozen food packaging. HDPE film has good toughness, and its tensile strength and heat resistance are superior to LDPE, making it suitable for paper-like films used in shopping bags, etc. LLDPE film has higher tensile and impact strength, and is less expensive, making it suitable for everyday consumer goods packaging.

[0003] A search revealed Chinese Patent Publication No. CN218660129U, which discloses a multifunctional pressing device for the production of biodegradable plastic film. This device provides a solution that is significantly different from the prior art. Specifically, this invention provides a multifunctional pressing device for the production of biodegradable plastic film to solve the problem mentioned in the background art where, during the film removal process, the plastic film adheres to the moving plate or the fixed seat, which easily tears the film and makes film removal difficult.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: it is difficult to stretch the film and it cannot be filled quickly. In industrial production, the difficulty in filling the film requires more time and effort to complete the filling operation, which slows down the entire production process and reduces the output per unit time. Due to the slow filling speed, it may be necessary to increase the number of operators to complete the filling work, or the operators may need to spend more time and effort to complete the filling task, which will lead to an increase in labor costs.

[0021] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0022] This application discloses a double-layer film pressing and molding device for processing food packaging bags.

[0023] like Figure 1 As shown, a double-layer film pressing and molding equipment for food packaging bag processing includes an operating table 1 and a film 10.

The fixing component 20 includes a placement opening 203 for placement, and the supporting component 21 includes two supporting rods 212 for spreading.

[0024] Please see Figure 3 The fixing component 20 includes a fixing block 201 fixedly installed on the top of the operating table 1. A hinge block 202 is hinged to the top of the fixing block 201. A placement opening 203 is opened on one side of the hinge block 202 and the fixing block 201. A limiting block 204 is hinged to the top of the hinge block 202. A handle 210 is fixedly installed on the top of the limiting block 204. A second placement opening 205 is opened on one side of the limiting block 204. A first rotating roller 206 is placed inside the first placement opening 203. A second rotating roller 207 is placed inside the second placement opening 205. A film 10 is wrapped around the outer walls of the first rotating roller 206 and the second rotating roller 207. The hinge block 202 and the limiting block 204 are opened by manually pulling the handle 210. Then, the first rotating roller 206 and the second rotating roller 207 are placed by manual labor. Finally, the opening is closed by manual labor. This avoids the need for operators to spend more time and effort to complete the filling task, which would otherwise lead to an increase in labor costs.

[0025] Please see Figure 3 The top of the fixing block 201, the hinge block 202 and the limiting block 204 are provided with a pin port 208. A limiting strip 209 is inserted into the pin port 208. By inserting the limiting strip 209 into the pin port 208, the block is sealed, thus achieving the function of rapid filling.

[0026] Please see Figure 4 The support assembly 21 includes two square plates 211 fixedly installed, and two support rods 212 rotatably connected between the two square plates 211. The support assembly 21 is used to separate the two films 10 during pressing, so as to avoid them sticking together in advance and causing problems during pressing.

[0027] The top of the operating table 1 is also provided with a pressing mechanism 3, which includes a pressing block 35 for pressing.

[0028] Please see Figure 4The pressing mechanism 3 includes two support columns 31 fixedly installed on the top of the operating table 1.

Two electric telescopic rods 34 are fixedly installed at the bottom of the mounting frame 33. The pressing block 35 is fixedly installed at the output end of the electric telescopic rod 34. By activating the electric telescopic rod 34, it is pressed down, thereby contacting the extrusion plate 37 and pressing the two layers of film 10 together.

[0029] Please see Figure 4 Multiple springs 36 are fixedly installed on the top of the operating table 1. The top of the multiple springs 36 are fixedly connected to the extrusion plate 37. The pressing block 35 is in contact with the extrusion plate 37. The film 10 is located between the extrusion plate 37 and the pressing block 35. When pressed down, the compression springs 36 are used for buffering, which can effectively avoid scratches, damage or deformation on the surface of the film 10 due to excessive pressure.

[0030] The top of the operating table 1 is also provided with a winding mechanism 4, which includes a winding roller 46 for winding.

[0031] Please see Figure 2 The winding mechanism 4 includes a U-shaped block 41 fixedly installed on the top of the operating table 1. A rectangular block 43 is hinged to the top of the U-shaped block 41. Placement slots 42 are provided on both sides of the rectangular block 43 and the U-shaped block 41. A circular hole 44 is provided on the top of the U-shaped block 41 and the rectangular block 43. A cylinder 45 is inserted into the inside of the circular hole 44. The winding roller 46 is placed inside the placement slot 42. A motor 48 is fixedly installed on one side of the winding roller 46. A placement block 47 is fixedly installed on the top of the operating table 1. The motor 48 is engaged with the placement block 47. By starting the motor 48, the winding roller 46 is driven to rotate, thereby winding up the pressed film 10, which effectively improves the work efficiency. The rectangular block 43 is opened by manually holding it and pulling it, thereby achieving the purpose of quick picking.

[0032] The installed fixing component 20 is used for quick filling, avoiding the need for operators to spend more time and effort to complete the filling task, which would increase labor costs. The installed support component 21 is used to separate the two films 10 during pressing, preventing them from sticking together in advance and causing problems during pressing. The installed pressing mechanism 3 is used for buffering, which can effectively prevent scratches, damage or deformation of the film 10 surface due to excessive pressure. The installed winding mechanism 4 is used to wind up the film after pressing, which effectively improves work efficiency.

[0033] The implementation principle of the double-layer film compression molding equipment for food packaging bag processing in this application embodiment is as follows: The installed fixing component 20 is used for rapid filling, avoiding the need for operators to spend more time and effort to complete the filling task, which would increase labor costs. The installed support component 21 is used to separate the two films 10 during compression, preventing them from sticking together prematurely and causing compression problems. The installed compression mechanism 3 is used for buffering, effectively preventing scratches, damage, or deformation of the film 10 surface due to excessive pressure. The installed winding mechanism 4 is used to wind up the film after compression, effectively improving work efficiency. The hinge block 202 and the limiting block 204 are opened by manually pulling the handle 210, and then the rotating roller 1 206 and the rotating roller 207 are placed manually, followed by manual closure, avoiding the need for operators to spend excessive time and effort. More time and effort are needed to complete the filling task, which will lead to an increase in labor costs. By inserting the limit strip 209 into the pin hole 208 to seal it, the filling function is achieved quickly. The installed support component 21 is used to separate the two films 10 during pressing, so as to avoid them sticking together in advance and causing problems in pressing. By activating the electric telescopic rod 34, it is pressed down to contact the extrusion plate 37, thereby pressing the two layers of film 10 together. At the same time as pressing down, the compression spring 36 is used for buffering, which can effectively avoid scratches, damage or deformation of the film 10 surface due to excessive pressure. By activating the motor 48, the winding roller 46 is driven to rotate, thereby winding up the pressed film 10, which effectively improves work efficiency. The rectangular block 43 is opened by manually holding it and prying it open, thereby achieving the purpose of quick picking.

[0034] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
