Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of packaging box sealing equipment, and in particular to a box body limiting component of a food packaging box sealing machine. Background Technology
[0002] Existing food packaging cans mainly consist of two parts: the box body and the easy-tear top cap. When packaging food, the opening of the box body needs to be sealed with the easy-tear top cap to prevent the food from coming into contact with the outside world and spoiling. At present, the sealing is generally done by a food packaging can sealing machine. The operation steps are as follows: First, place the easy-tear top cap at the opening of the box body, then place the box body in the placement platform at the top of the workbench. The box body is limited by the holding cavity in the placement platform. Then, the telescopic mechanism is activated to drive the placement platform to rise and contact the rotating pressure roller. The pressure roller folds the edge of the easy-tear top cap. During the folding process, the pressure roller will carry the box body and the easy-tear top cap into the air, so that the box body leaves the placement platform. When the pressure roller stops moving and releases the box body, the box body will fall freely back to the placement platform.
[0003] The existing sealing machines have the following problems: The existing placement platform only fixes the bottom of the box through the receiving cavity. Since the receiving cavity is usually shallow, the contact area between the side of the box and the receiving cavity is small. During the process of the sealing arm driving the pressure roller to fold the top easy-tear cap, the box is prone to shaking and there is a risk of it flying off the placement platform, resulting in sealing failure and the need for secondary sealing. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a box limiting component for a food packaging box sealing machine, so as to solve the technical problem that the placement table of the sealing machine on the market lacks a stable box limiting structure, which causes the box to fall off the placement table during the sealing process.
[0005] To achieve the above objectives, this utility model provides a box body limiting component for a food packaging box sealing machine, comprising:
[0006] The placement platform has a cavity at its upper end for positioning the bottom of the box.
[0007] A drive component for driving the placement stage to move the box body toward the processing station;
[0008] The box-body limiting assembly further includes multiple limiting mechanisms for positioning the sides of the box body, the limiting mechanisms including:
[0009] The limiting baffle has an arc-shaped limiting surface that matches the outer circumferential surface of the box. All the arc-shaped limiting surfaces of the limiting mechanisms are located on the side of the same virtual frustum. The centerlines of the receiving cavity, the virtual frustum and the box coincide with each other. In use, the bottom of the box is placed in the receiving cavity of the placement platform and the side of the box is in contact with the limiting baffle, thereby preventing the box from detaching from the placement platform.
[0010] As a preferred embodiment of this utility model, the limiting mechanism further includes an electric telescopic rod, the bottom of which is fixed to the outside of the placement platform, and the output end of the electric telescopic rod is connected to the limiting baffle.
[0011] As a preferred technical solution of this utility model, the output end of the electric telescopic rod is connected to a connecting rod, and an elastic structure is provided between the connecting rod and the limiting baffle. The elastic structure is used to drive the limiting baffle to move inward along the radial direction of the virtual frustum after the box body is separated from the receiving cavity.
[0012] As a preferred embodiment of this utility model, the elastic structure includes:
[0013] A connecting body, which is connected to the connecting rod;
[0014] A sliding rod is disposed on one side of the limiting baffle, and the sliding rod is slidably engaged with a sliding groove formed in the connecting body;
[0015] The abutment plate is integrally formed with one end of the slide rod;
[0016] A spring, one end of which is disposed in the groove, and the other end of which abuts against the abutment.
[0017] As a preferred embodiment of this utility model, the limiting mechanism further includes: a plurality of rubber strips, which are disposed on the inner wall of the limiting baffle to improve the coefficient of friction between the limiting baffle and the box body.
[0018] As a preferred embodiment of this utility model, the limiting mechanism further includes:

[0020] As a preferred embodiment of this utility model, the upper end of the switch is provided with a supporting base plate, and the upper end of the supporting base plate is provided with an anti-slip pad.
[0021] As a preferred embodiment of this utility model, there are two limiting mechanisms, and the two limiting mechanisms are symmetrically arranged about the left and right sides of the placement platform.

[0023] Base;
[0024] A hydraulic rod is connected to the base at the bottom, and the output end of the hydraulic rod is connected to the lower end of the placement platform.
[0025] As a preferred embodiment of this utility model, the surface of the base is provided with a plurality of mounting holes, and a connector is provided in the mounting holes.
[0026] The beneficial effects of this utility model are as follows: By setting a limiting baffle on the side of the placement platform, the arc-shaped limiting surface of the limiting baffle can fit with the outer side of the box. Combined with the original receiving cavity on the placement platform, the bottom and sides of the box can be positioned more stably, thereby effectively preventing the box from detaching from the receiving cavity and falling off the placement platform during the sealing process, which is conducive to improving production efficiency.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0036] like Figure 1 As shown, a box-body limiting assembly for a food packaging box sealing machine includes: a placement platform 1 with a receiving cavity 5 at its upper end for positioning the bottom of a box 17; a driving component for driving the placement platform 1 to move the box 17 to the processing station; the box-body limiting assembly also includes multiple limiting mechanisms for positioning the sides of the box 17, each limiting mechanism including: a limiting baffle 10 with an arc-shaped limiting surface matching the outer circumferential surface of the box 17, all the arc-shaped limiting surfaces of the limiting mechanisms being located on the side of the same virtual frustum, the center lines of the receiving cavity 5, the virtual frustum and the box 17 coinciding with each other, in use, the bottom of the box 17 is placed in the receiving cavity 5 of the placement platform 1 and the side of the box 17 is in contact with the limiting baffle 10, thereby preventing the box 17 from detaching from the placement platform 1;
[0037] The above technical solution can limit the sides and bottom of the box 17 respectively. When in use, after the box 17 is placed in the receiving cavity 5 of the placement table 1, the arc-shaped limiting surface of the limiting baffle 10 can fit with the side of the box 17, thereby restricting the movement of the box 17 in the radial direction of the receiving cavity 5. During processing, the driving component drives the placement table 1 to rise. When the pressure roller folds the top easy-tear cover of the upper end of the box 17, the limiting baffle 10 can prevent the box 17 from shaking and falling off the placement table 1.
[0038] like Figure 1 As shown, in this embodiment, there are two limiting mechanisms, and the two limiting mechanisms are symmetrically arranged about the left and right sides of the placement platform 1. The limiting mechanism also includes an electric telescopic rod 6, the bottom of which is fixed to the outside of the placement platform 1, and the output end of the electric telescopic rod 6 is connected to the limiting baffle 10.
[0039] The above technical solution allows for adjustment of the spacing of the limiting baffles 10 according to different specifications of the box 17.
[0040] like Figure 3 and Figure 4 As shown, in this embodiment, the output end of the electric telescopic rod 6 is connected to a connecting rod 7. An elastic structure is provided between the connecting rod 7 and the limiting baffle 10. The elastic structure is used to drive the limiting baffle 10 to move inward along the radial direction of the virtual frustum after the box 17 is separated from the receiving cavity 5. Specifically, the elastic structure includes: a connecting body 8, which is connected to the connecting rod 7; a sliding rod 11, which is disposed on one side of the limiting baffle 10, and the sliding rod 11 slides in conjunction with the sliding groove 9 opened in the connecting body 8; a stop plate 12, which is integrally formed with one end of the sliding rod 11; and a spring 13, one end of which is disposed in the sliding groove 9, and the other end of the spring 13 abuts against the stop plate 12.
[0041] The above technical solution can reduce the falling distance of the box 17 and prevent the box 17 from being damaged. Since the limit baffle 10 is set, it can prevent the box 17 from shaking and falling off the placement table 1. During the folding process, the pressure roller will lift the box 17. At this time, the spring 13 will push the slide rod 11 to slide. The slide rod 11 drives the limit baffle 10 to move, so that the distance between the two limit baffles 10 is reduced. After processing, when the box 17 falls, it can quickly contact the limit baffle 10, reducing the distance when the box 17 falls and preventing the box 17 from being deformed by the fall.
[0042] like Figure 3 and Figure 5 As shown, in this embodiment, the limiting mechanism further includes: a plurality of rubber strips 14, which are disposed on the inner wall of the limiting baffle 10;
[0043] The above technical solution can improve the friction coefficient between the arc-shaped limiting surface of the limiting baffle 10 and the outer side of the box 17, and prevent the box 17 from sliding after it is fixed.
[0044] like Figure 3 As shown, in this embodiment, the limiting mechanism further includes: a switch 16, which is disposed in the receiving cavity 5 and is electrically connected to the electric telescopic rod 6; a supporting base plate 15 is provided at the upper end of the switch 16, and an anti-slip pad is provided at the upper end of the supporting base plate 15.
[0045] The above technical solution can automatically drive the electric telescopic rod 6 to place the box 17 in the receiving cavity 5 of the placement platform 1. The bottom of the box 17 touches the support base plate 15 and moves it downward. The support base plate 15 presses the switch 16, and the switch 16 starts the electric telescopic rod 6. The electric telescopic rod 6 drives the limit baffle 10 to clamp the box 17.
[0046] like Figure 3As shown, in this embodiment, the driving component includes: a base 3; a hydraulic rod 2 connected to the base 3 at its bottom, with the output end of the hydraulic rod 2 connected to the lower end of the placement platform 1;
[0047] The above technical solution can drive the placement table 1 to rise and fall, so that the box 17 on the placement table 1 can enter the processing station.
[0048] like Figure 3 As shown, in this embodiment, the surface of the base 3 is provided with a plurality of mounting holes 4, and a connector is provided in the mounting holes 4;
[0049] Using the above technical solution, the base 3 can be placed on the worktable of the sealing machine, and bolts can be passed through the mounting holes 4 of the base 3 and threaded through the worktable to complete the installation.
[0050] Working principle: During use, the box body 17 is placed in the receiving cavity 5 of the placement table 1. The bottom of the box body 17 touches the support base plate 15, causing it to move downwards. The support base plate 15 presses the switch 16, which activates the electric telescopic rod 6. The electric telescopic rod 6 drives the connecting rod 7 to move, which in turn drives the connecting body 8 to move. The connecting body 8 then drives the sliding rod 11 to move, which in turn drives the limiting baffle 10 to clamp and limit the side of the box body 17. During processing, the hydraulic rod 2 drives the placement table 1 to rise. When the pressure roller presses against the box body 17... When the top easy-tear cap is folded, the limit baffle 10 prevents the box 17 from shaking and falling off the placement table 1. During the folding process, the pressure roller lifts the box 17, and the spring 13 pushes the slide bar 11 to slide. The slide bar 11 drives the limit baffle 10 to move, making the distance between the two limit baffles 10 smaller. After processing, when the box 17 falls, it can quickly contact the limit baffle 10, reducing the distance when the box 17 falls and preventing the box 17 from being deformed by the fall.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
