Description

Technical Field

[0001] The utility model relates to the technical field of lunch box processing equipment, in particular to a lunch box pulling and ejecting mechanism and lunch box processing equipment. Background Art

[0002] With the development of the economy and technology, people are paying more and more attention to food safety, and the development of food packaging materials is also changing with each passing day. Aluminum foil is a safe and environmentally friendly material often used for green food packaging, as it is lightweight, low density, has high barrier properties, light-blocking properties, UV resistance, moisture resistance, corrosion resistance, good thermal insulation, long shelf life, good ductility and flexibility, and is highly recyclable.

[0003] Currently, in small-scale aluminum foil lunch box forming equipment, after the aluminum foil is stamped and formed, the aluminum foil mold needs to be removed from the equipment and then the aluminum foil lunch box needs to be ejected, so there are many steps and the operation is cumbersome. Utility Model Content

[0004] The problem solved by the utility model is that there are many steps to remove the aluminum foil lunch box from the mold, and the operation is complicated.

[0005] In order to solve the above problems, the utility model provides a lunch box pull-out ejection mechanism, which includes: a bracket, which includes a horizontal guide rail and an inclined guide rail; a lunch box lower mold, which includes: a pull-out sliding part, a vertical guide rail and a lunch box accommodating groove, the pull-out sliding part is slidably connected to the horizontal guide rail, and the vertical guide rail and the lunch box accommodating groove are respectively connected to the pull-out sliding part; an ejector, which includes: a top plate, a vertical sliding part and an inclined sliding part, the top plate is located below the lunch box accommodating groove, the vertical sliding part is connected to the top plate and is slidably connected to the vertical guide rail, and the inclined sliding part is connected to the top plate and is slidably connected to the inclined guide rail.

[0006] The technical effect achieved by adopting this technical solution is as follows: After the aluminum foil lunch box is stamped and formed, the lower mold of the lunch box is pulled out, that is, the pull-out sliding part is pulled out along the horizontal guide rail, and the lunch box receiving slot, the lunch box installed therein, and the vertical guide rail all move outward; the vertical guide rail pulls the vertical sliding part, causing the ejector to slide outward as a whole; during the process of the inclined sliding part sliding outward along the inclined guide rail, the vertical sliding part slides upward along the vertical guide rail, and the top plate also moves upward accordingly; because the top plate corresponds to the lunch box receiving slot, the top plate can eject the aluminum foil lunch box in the lunch box receiving slot during the upward movement. When the lower mold of the lunch box is at its outermost extreme position, the top plate is at its extreme position closest to the lunch box receiving slot; therefore, only the action of pulling out the lower mold of the lunch box can simultaneously realize the ejection of the aluminum foil lunch box, saving operating steps and making the removal of the aluminum foil lunch box more convenient and quick.

[0007] Furthermore, the bracket includes: two side brackets arranged opposite to each other, each of the side brackets is provided with a horizontal guide rail and an inclined guide rail, and the lower mold of the lunch box slides between the two side brackets.

[0008] The technical effects achieved after adopting this technical solution are as follows: the two side brackets support the lower mold of the lunch box through two horizontal guide rails, making the stamping and removal of the aluminum foil lunch box more stable; the two side brackets support the ejector through two inclined guide rails, making the relative sliding of the vertical sliding part and the vertical slide rail smoother and the ejection action of the top plate more precise.

[0009] Furthermore, there is a sliding channel between the two side brackets for the sliding of the lower mold of the lunch box; one end of the sliding channel is an opening; wherein, the end of the inclined guide rail close to the opening is higher than the end of the inclined guide rail away from the opening.

[0010] The technical effect achieved after adopting this technical solution is: when the lower mold of the lunch box moves to the outside of the opening, the inclined sliding part moves to the highest end of the inclined guide rail, so that the top plate is also located at the highest end, thereby ejecting the aluminum foil lunch box.

[0011] Furthermore, the horizontal guide rail includes a horizontal slide groove, and the horizontal slide groove faces the sliding channel.

[0012] The technical effect achieved after adopting this technical solution is: the horizontal slide groove faces inward, and after the pull-out sliding part cooperates with the horizontal slide groove, the upper and lower sides of the horizontal slide groove can limit the pull-out sliding part, and the left and right horizontal slide grooves can together limit the edge of the pull-out sliding part, thereby improving the installation accuracy of the pull-out sliding part, and the pull-out sliding part will not move in directions other than the sliding direction.

[0013] Furthermore, the pull-out sliding portion is a horizontal plate-shaped structure, and the pull-out sliding portion cooperates with the horizontal sliding groove; wherein, the lunch box accommodating groove is installed on the pull-out sliding portion.

[0014] The technical effect achieved after adopting this technical solution is: the pull-out sliding part is a plate-like structure, which is lighter and convenient for manually pulling out the lower mold of the lunch box; at the same time, the plate-like structure also facilitates the clamping and positioning of the horizontal slide groove.

[0016] The technical effect achieved by adopting this solution is that the inclined sliding part uses rollers to reduce friction between it and the inclined guide rail, thereby facilitating the manual sliding of the ejector. Rollers are provided on both sides of the vertical sliding part, making the ejector slide out of the sliding channel smoother and more stable.

[0017] Furthermore, a handle is provided at one end of the pull-out sliding portion away from the sliding channel.

[0018] The technical effect achieved after adopting this technical solution is: the handle is convenient for holding and pulling the sliding part, and it is convenient to pull the lower mold of the lunch box to take out the aluminum foil lunch box.

[0019] Furthermore, the vertical sliding portion is provided with at least one through hole opened in a vertical direction, the vertical guide rail passes through the through hole, and the cross section of the vertical guide rail matches the through hole.

[0020] The technical effect achieved after adopting this technical solution is: the through hole can limit the installation state of the vertical sliding part, that is, when the vertical guide rail pulls the vertical sliding part, the vertical sliding part will not tilt due to the friction between the inclined sliding part and the inclined guide rail, so that it can be lifted and lowered stably along the vertical guide rail.

[0021] Furthermore, the vertical sliding portion is provided with at least one fixing hole; the top plate is provided with at least one waist hole; the fixing hole can be fixed to any position of the waist hole by a fastener to adjust the distance between the top plate and the lower mold of the lunch box.

[0022] The technical effect achieved after adopting this technical solution is: by changing the position of the fastener and the waist hole, the vertical position of the top plate can be adjusted, that is, when the inclined sliding part is located at the end of the inclined guide rail closest to the opening, the top plate is closest to the lunch box accommodating groove. At this time, the height of the top plate is adjusted to adapt to aluminum foil lunch boxes of different depths, and the timing of ejection can also be adjusted for the same lunch box.

[0023] The utility model also provides a lunch box processing device, including a lunch box pull-out and ejection mechanism as provided in any of the above technical solutions, and also including a lunch box stamping mechanism, which is arranged on the bracket; when the lunch box lower mold slides into the bracket, the lunch box stamping mechanism is located above the lunch box lower mold.
