Description

Technical Field

[0001] This application belongs to the field of packaging technology, specifically relating to a novel dual-head synchronous pressing assembly and pressing system. Background Technology

[0002] After upgrading the outer packaging of a high-end liquor, the lid locking structure was changed from a riveted structure to a self-locking structure. The lid currently locks by manually tapping the top of the box to create downward pressure and lock it in place. Each lid has four engagement points, requiring multiple taps to complete the operation. The force, angle, and position of these taps are uncontrollable, easily leading to defects such as improper lid pressing, lid breakage, and cracks, posing quality risks. Furthermore, this method requires prolonged standing to tap the boxes, which can cause fatigue, and performing the tapping operation on a conveyor line presents certain safety hazards.

[0003] Therefore, a box-pressing system can be designed to automatically press the box body and lid together via PLC programming control. In the initial research phase, a single pressure head was used for lid fastening. However, due to the multi-interlocking design of the lid, even with moderate downward pressure from a single head, uneven pressure often resulted in one end of the lid lifting up, causing fastening failure. Increasing the downward pressure ensured consistent fastening pressure at each point, but this also risked excessive compression, damaging the material and affecting the quality of the wine box. Utility Model Content

[0004] The purpose of this application is to provide a novel dual-head synchronous pressing assembly and pressing system, which ensures that the lid and body of the box are pressed together without damage or cracks, meets the requirements of the production process, and solves the quality problems caused by manual or single-head pressing of wine boxes.

[0005] The objective of this application is achieved through the following technical solution:

[0006] A novel dual-head synchronous pressing box assembly includes a pressing head cylinder bracket, on which two vertical pressing head cylinders are mounted. The telescopic ends of the lower ends of the pressing head cylinders are connected to the synchronous pressing heads, and a single-box pressing gap is formed between the two synchronous pressing heads.

[0007] Furthermore, the pressure head cylinder bracket has a U-shaped structure.

[0008] Furthermore, the pressure head cylinder bracket includes a horizontal bar, a vertical bar, and a vertical bar forming a cuboid structure. Two mounting plates are connected between the horizontal bars, and a pressure head cylinder is provided on each of the two mounting plates.

[0009] Furthermore, the synchronous pressure head is a long strip structure made of PE plastic.

[0010] Furthermore, the upper end face of the synchronous pressure head has a groove for connecting the pressure head cylinder.

[0011] Furthermore, the lower end face of the synchronous pressure head is a horizontal downward pressure surface.

[0012] Furthermore, the bottom sides of the pressure head cylinder bracket are provided with inward-facing retaining strips.

[0013] A novel dual-head synchronous pressing box system includes a conveyor chain and the aforementioned novel dual-head synchronous pressing box assembly, with two synchronous pressing heads located above the conveyor chain.

[0014] Furthermore, the pressure head cylinder bracket is equipped with a positioning sensor, which is electrically connected to the control box.

[0015] Furthermore, the pressure head cylinder is connected to the air supply assembly, and the solenoid valve of the air supply assembly is electrically connected to the control box.

[0016] The functions implemented in this application are:

[0017] (1) From the perspective of production cost, brackets are installed at the existing conveyor line location for cylinder pressing base and box detection photoelectric frame installation.

[0018] (2) A double cylinder is installed on the top of the wine box to physically press the lid and achieve perfect pressing of the corresponding wine box.

[0019] (3) Install the control cabinet, write the control program, and set the signal holding time on site according to the time it takes for the box cover to pass through the pressure head cylinder, so as to effectively ensure that the box cover is pressed intact and undamaged.

[0020] The beneficial effects of this application are:

[0021] (1) The double-head snapping method is adopted. The two heads work synchronously and can press evenly from both sides. The heads can act at each biting point to ensure that the structure of the biting point is properly engaged.

[0022] (2) The double pressure head has a small contact area, which ensures that other parts of the lid can deform freely and avoids the pressure head restricting the lid structure, thereby avoiding stress concentration and structural damage.

[0023] (3) The overall system structure is simple and can be flexibly installed on the top of the conveyor chain, which brings high efficiency of automated operation, excellent operation quality, and will not cause damage to the box cover.

[0024] The aforementioned main solution and its various further alternatives can be freely combined to form multiple solutions, all of which are solutions that can be adopted and are claimed in this application; furthermore, the (non-conflicting alternatives) can also be freely combined with each other and with other alternatives. Those skilled in the art, after understanding this solution, will realize from the prior art and common general knowledge that there are many combinations, all of which are technical solutions to be protected in this application, and will not be exhaustively listed here.

[0029] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0030] Example 1

[0031] refer to Figure 1 and Figure 2 As shown, a novel dual-head synchronous pressing box assembly includes a pressing head cylinder bracket 4, a pressing head cylinder 5, a synchronous pressing head 6, and a stop bar 10.

[0032] The pressure head cylinder bracket 4 serves as the base for the assembly, allowing the entire assembly to be positioned above the conveyor chain 1. It can be a transverse, suspended, or cantilever structure. The pressure head cylinder bracket 4 is equipped with two vertical pressure head cylinders 5, which provide the power for the pressure head to move up and down.

[0033] The telescopic end of the lower end of the pressure head cylinder 5 is connected to the synchronous pressure head 6, and the two pressure head cylinders 5 are used to achieve independent control of the two pressure heads. Although the pressure heads are independently controlled, the two pressure heads move synchronously when moving up and down.

[0034] A single box pressing gap is formed between the two synchronous pressing heads 6. When the box body 2 and the box cover 3 are located below the two pressing heads, the two pressing heads act on both sides (two straight long sides) of the box cover 3 respectively, and evenly fasten the box cover 3 into the box body 2, ensuring effective engagement of the biting points, and the area of ​​action on the box cover 3 is small, so as not to cause too much constraint on the box cover 3.

[0035] The pressure head cylinder bracket 4 has a portal-shaped structure and is arranged on the frame on both sides of the conveyor chain 1, so that two synchronous pressure heads 6 can span across the top of the conveyor chain 1.

[0036] The pressure head cylinder bracket 4 includes a horizontal bar, a vertical bar, and a vertical bar. The horizontal bar, vertical bar, and vertical bar are welded together to form a cuboid structure. To achieve the U-shaped structure of the bracket, the horizontal bar and vertical bar are both arranged at the upper position, leaving space below to allow the conveyor chain 1 to cross. Two mounting plates are welded together between opposite horizontal bars, and pressure head cylinders 5 are mounted on both mounting plates by screws.

[0037] The synchronous pressure head 6 is a long strip structure made of PE plastic to match the side pressing of the lid 3. The upper end face of the synchronous pressure head 6 has a groove for connecting the pressure head cylinder 5. The telescopic end of the pressure head cylinder 5 extends into the groove and is fixed with screws. The lower end face of the synchronous pressure head 6 is a horizontal pressing surface, which allows direct contact with the lid 3. The horizontal pressing surface ensures uniform pressing action.

[0038] The bottom sides of the pressure head cylinder bracket 4 are provided with inward-facing baffles 10. The baffles 10 are welded to the vertical rod of the bracket and arranged along the direction (longitudinal) of the conveyor chain 1 to form a limiting guide structure on both sides to guide the box body 2 entering the bracket.

[0039] Example 2

[0040] refer to Figures 1-3 As shown, a novel dual-head synchronous pressing box system includes a conveyor chain 1, a positioning sensor 7, a control box 8, and a solenoid valve 9, and also includes the novel dual-head synchronous pressing box assembly of Embodiment 1.

[0041] The conveyor chain 1 continuously transports the box body 2, while the box lid 3 is placed at the opening of the box body before entering the support. Two synchronous pressure heads 6 are located above the conveyor chain 1. When the box body 2 and the box lid 3 enter the support, the two synchronous pressure heads press down synchronously to close the box lid 3 into the box body 2.

[0042] A position sensor 7 (photoelectric sensor) is installed on the pressure head cylinder bracket 4. The position sensor 7 is electrically connected to the control box 8 (PLC) and is used to detect when the box body 2 reaches below the pressure head. The pressure head cylinder 5 is connected to the air supply assembly. The solenoid valve 9 of the air supply assembly is electrically connected to the control box 8. When the box body 2 and the box cover 3 are in position, the solenoid valve 9 is controlled to supply air to the cylinder through the air supply assembly to achieve downward pressure. After pressing for a period of time, the solenoid valve 9 is controlled again to supply air to the cylinder through the air supply assembly to achieve upward pressure.

[0043] The working process of this embodiment:

[0044] (1) Detection and pressing: When the unpressed box body is conveyed on the wine bottle conveyor line and there is a gap, the arrival of the box body can be detected by the box detection photoelectric sensor. The detection signal is transmitted to the control box. Through PLC logic control, the control signal is output to the solenoid valve. The solenoid valve receives the signal and reverses. The pressure head cylinder changes air and presses down to drive the PE plastic pressure head to press the box lid, thus completing the wine box lid pressing action.

[0045] (2) Press-Hold-Lift: The press head cylinder starts pressing down and timing begins. The pressing is maintained according to the time set by the PLC in the control box (10-1000ms) to ensure that the cover fits completely. When the pressing time reaches the set value, the control signal to the solenoid valve is disconnected through the PLC logic control. The solenoid valve coil is de-energized and reverses again. The press head cylinder is then pneumatically lifted, causing the PE plastic press head to detach from the cover box, completing one press-hold-lift action.

[0046] (3) Repeated cycle: The cylinder of the press head lifts up and drives the PE plastic press head to detach from the pressed product. The finished product moves to the right under the action of the conveyor line. The unpressed wine box enters the pressing station to complete the pressing of the box lid. Repeated cycle to achieve non-destructive box pressing.

[0047] Advantages of this embodiment:

[0048] (1) Considering the overall economic benefits, Siemens PLC S7-200 was selected as the controller, which is low in cost and stable in operation. A dual-cylinder structure was adopted as the pressing cylinder to increase the effective force-bearing area of ​​the lid.

[0049] (2) The pressure head structure is made of PE plastic sheet with good rigidity, toughness and mechanical strength. The double pressure head structure can make good contact with the box cover, ensuring pressure while effectively protecting the hot stamping strip of the box cover.

[0050] (3) Using sensor detection technology and PLC logic control technology, the automatic control of box cover detection and cylinder box cover pressing is realized.

[0051] (4) Operators no longer need to frequently tap the box lid by hand, eliminating the need for operators in this section and reducing the labor intensity of employees.

[0052] (5) Comparison of the effects of manual and mechanical baffles:

[0054] Key points of this application:

[0055] (1) It solved the problem of automatic and non-destructive pressing of boxed products, saving 3 employees.

[0056] (2) The device effectively utilizes the orderly combination of sensors, cylinders, PLCs and control programs to achieve automatic pressing of wine boxes by effectively utilizing the gap between the lids.

[0057] (3) Unique pressure head structure and material selection ensure 100% success rate of lid snapping and meet snapping quality standards.
