Description

Technical Field

[0001] This application relates to the field of lunchbox forming equipment, and in particular to a sheet compaction production equipment for lunchboxes. Background Technology

[0002] With the rapid development of the global food delivery industry and the increasing environmental awareness of consumers, the demand for disposable food containers (especially those made of biodegradable materials) has exploded. The blister packaging process is widely used in the production of these containers.

[0003] Before the common food container is blister-formed, the raw material of the food container is in sheet form. The sheet material has poor density and poor surface smoothness, which affects the texture of the product. Summary of the Invention

[0004] To improve the quality of products, this application provides a sheet compaction production equipment for lunch boxes.

[0005] This application provides a sheet compaction production equipment for lunch boxes, which adopts the following technical solution: A sheet compaction production device for lunch boxes includes a base, a first guide roller rotatably mounted on the base, a second guide roller mounted parallel to the first guide roller, grooves on both sides of the base, and adjusting blocks rotatably mounted at both ends of the second guide roller. The adjusting blocks slide along the length of the grooves, and the sliding directions of the first and second guide rollers are either moving away from or towards each other. The device also includes an adjustment mechanism for driving the adjusting blocks to slide along the length of the grooves.

[0006] By adopting the above technical solution and setting up production molding equipment, the food container raw material sheet is squeezed by two guide rollers, resulting in better density of the food container raw material sheet and improved product texture. At the same time, adjustment blocks are set at both ends of the second guide roller to facilitate adjustment of the second guide roller.

[0007] Optionally, the adjustment mechanism includes several screws and several nuts. Both ends of the adjustment block are provided with protrusions. The groove has sliding grooves on its opposite side walls. The protrusions slide along the length of the groove. The base has several through holes that penetrate the base. The protrusions have at least one connecting hole. The screws pass through the through holes and the connecting hole. The nuts are threaded to the screws.

[0008] By adopting the above technical solution, the adjusting block is fixed by screws and nuts, making it difficult for the guide roller to fall out of the groove during operation. Several through holes are opened to facilitate the adjustment of the adjusting block, so that the adjusting block can select through holes of different heights according to the thickness of the food container raw material sheet. The adjusting block allows the second guide roller to meet more scenarios with different thicknesses of food container raw material sheets.

[0009] Optionally, both the first guide roller and the second guide roller are wrapped with a polyurethane layer.

[0010] By adopting the above technical solutions, the polyurethane layer has good high temperature resistance, good elasticity, tear resistance, oil resistance, and strong load-bearing capacity.

[0011] Optionally, the surface roughness Ra of the polyurethane layer is ≤0.04μm.

[0012] By adopting the above technical solution, the lower surface roughness Ra≤0.04μm makes the polyurethane layer smoother, which can effectively reduce the fine scratches on the sheet surface caused by friction, and at the same time improve the brightness of the plastic lunch box sheet to a certain extent.

[0013] Optionally, the adjustment mechanism is a driving component, which corresponds to an adjustment block. The driving component is located on the top of the base and is used to drive the adjustment block to slide vertically.

[0014] By adopting the above technical solution, when the adjusting block needs to be adjusted, the adjusting block is driven to slide vertically by the driving component, making the adjusting block easy to adjust and allowing for adjustment without stopping the machine. At the same time, the adjustment accuracy is high through the driving component.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. By extruding the food container material sheet through two guide rollers, the thickness of the food container material sheet is more stable, reducing material waste, and the density of the food container material sheet is better, thus improving the texture of the product; 2. The screws and nuts facilitate the adjustment and fixation of the adjustment block, and the through holes allow the adjustment block to accommodate different thicknesses of the food container material sheets; 3. The adjusting block is driven to slide vertically by the driving component, and the adjustment can be performed without stopping the machine. The driving component has high adjustment accuracy.

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

[0022] Embodiment 1 of this application discloses a sheet compaction production equipment for lunch boxes. (Refer to...) Figure 1 , Figure 2 , Figure 3 The sheet compaction production equipment for lunch boxes includes a base 1, on which a first guide roller 2 is rotatably connected. A second guide roller 3 is positioned parallel to the first guide roller 2. Grooves 4 are formed on both sides of the base 1. Adjusting blocks 5 are rotatably connected to both ends of the second guide roller 3, and the adjusting blocks 5 slide along the length of the grooves 4. The sliding direction of the first guide roller 2 and the second guide roller 3 is either moving away from or towards each other. Both the first guide roller 2 and the second guide roller 3 are covered with a polyurethane layer 8. The surface roughness Ra of the polyurethane layer 8 is ≤0.04μm.

[0023] Reference Figure 1 , Figure 2 , Figure 3 The sheet compaction production equipment for lunch boxes includes an adjustment mechanism 6 that drives an adjustment block 5 to slide along the length of a groove 4. The adjustment mechanism 6 includes several screws 61 and several nuts 62. Both ends of the adjustment block 5 are fixed with protrusions 71. Sliding grooves 72 are formed on opposite side walls of the groove 4, allowing the protrusions 71 to slide along the length of the groove 4. Several through holes 73 are formed on the base 1, penetrating the base 1. Two connecting holes 74 are formed on the protrusions 71, through which screws 61 pass and into the connecting holes 74. Nuts 62 are threadedly connected to screws 61.

[0024] The implementation principle of the sheet compaction production equipment for lunch boxes disclosed in Embodiment 1 of this application is as follows: After the lunch box raw material sheet is produced, the thickness between the two first guide rollers 2 and the second guide roller 3 is adjusted by adjusting block 5 according to the required thickness of the lunch box product, so as to accommodate more thicknesses of lunch box raw material sheet forming. After the height is adjusted, the adjusting block 5 is fixed by screws 61 to make the adjusting block 5 firmly installed. The lunch box raw material sheet passes between the two guide rollers, and the two guide rollers squeeze the lunch box raw material sheet, resulting in better density of the lunch box raw material sheet and improved product texture.

[0025] Example 2 Reference Figure 4The difference between this embodiment and Embodiment 1 is that the adjusting mechanism 6 is a driving component 63. Two driving components 63 are provided, each fixed to one of the opposite sides of the base 1. Each driving component 63 corresponds to an adjusting block 5. The driving components 63 are fixed to the top of the base 1, and a lead screw 91 is coaxially fixed to the output end of each driving component 63. The lead screw 91 is rotatably connected to the bottom of a groove and passes through the base 1. The adjusting block 5 has a threaded hole 92, through which it is threadedly connected to the lead screw 91. The driving component 63 drives the lead screw 91 to rotate, thereby causing the adjusting block 5 to slide vertically. Both driving components 63 are connected to the production management system, which can simultaneously start or stop them for production convenience. In this embodiment, the driving component 63 is an electric cylinder. When the adjusting block 5 needs adjustment, the driving component 63 drives it to slide vertically. Adjusting the adjusting block 5 is convenient and can be done without stopping the machine. Furthermore, the driving component 63 provides high adjustment precision.
