Description

Technical Field

[0001] The utility model relates to the field of carton printing and bonding, in particular to a carton printing and bonding device. Background Art

[0002] In the carton packaging industry, cardboards come in a variety of sizes and specifications. Traditional carton printing and gluing devices are often designed to be fixed in size or can only adapt to a limited range of cardboard sizes. When facing orders for cardboards of different sizes, single-size gluing devices need to be frequently replaced or adjusted, which not only increases production preparation time, but also limits the rapid response capability of the production line. Each time the equipment size is adjusted, it is necessary to stop the machine for manual adjustment or mold replacement, which not only consumes a lot of time, but also affects the overall production efficiency and capacity. Frequent manual adjustments may lead to problems such as inaccurate positioning and uneven clamping force, which affect the printing quality and the final bonding strength of the carton, and reduce the overall quality of the product. For production needs with variable sizes, companies may need to equip multiple sets of equipment with different specifications, which undoubtedly increases initial investment and maintenance costs.

DETAILED DESCRIPTION

[0026] like Figures 1 to 5 As shown, the carton printing and bonding device comprises a frame 1, in which a pressing plate 4 that slides up and down is provided inside the frame 1, a sliding and unfolding telescopic tooth plate 5 is provided at the end of the pressing plate 4, sliding side baffles 6 are provided on both sides of the telescopic tooth plate 5, the ends of the side baffles 6 slide against the placement platform 7 in the frame 1, and a rotating bidirectional screw 9 is provided between the side baffles 6 on both sides, and the bidirectional screw 9 is used to drive the side baffles 6 on both sides to move relative to each other. The pressing plate 4 that slides up and down drives the telescopic tooth plate 5 to move, so that the cardboard to be bonded is pressed on the placement platform 7, and the sliding and unfolding telescopic tooth plate 5 and the side baffle 6 can adjust the width of the pressed cardboard accordingly, and the side baffle 6 and the telescopic tooth plate 5 can be driven to expand or contract by rotating the bidirectional screw 9 to adjust the width of the pressing surface.

[0027] The frame 1 is the basic supporting structure of the entire device, providing the necessary stability and installation interface to ensure the coordinated operation of various components.

[0028] The pressing plate 4 that slides up and down is installed inside the frame and can slide in the vertical direction. The telescopic tooth plate 5 is installed at the end of the pressing plate 4 and can slide and expand, which increases the adaptability of the device. When the pressing plate 4 moves downward, the telescopic tooth plate 5 can adjust the pressing area to ensure that the cardboard is evenly and firmly fixed on the placement platform 7 to avoid displacement during printing or bonding.

[0029] The sliding side baffles 6 are located on both sides of the telescopic tooth plate 5 and can slide on the placement platform 7 in the frame. In this way, they directly participate in defining the lateral boundaries of the cardboard and ensure the alignment and stability of the cardboard.

[0030] The bidirectional screw 9 is installed between the side baffles, and the two side baffles 6 can be precisely controlled to move relative to each other by rotation. The size of the clamping area can be quickly adjusted according to the actual width of the cardboard, which also improves the accuracy and efficiency of the adjustment, and is a concentrated embodiment of the flexibility of the device.

[0031] Preferably, a pushing mechanism 2 and a guide column 3 are provided between the pressing plate 4 and the frame 1, and the guide column 3 is provided on both sides of the pushing mechanism 2;

[0032] The cylinder end of the push mechanism 2 is fixed on the frame 1, and the piston rod end is fixed on the pressure plate 4;

[0033] One end of the guide column 3 is fixed on the pressure plate 4, and the other end slides against the frame 1 through a sliding sleeve. The push mechanism 2 is a cylinder or a hydraulic cylinder, which drives the pressure plate 4 to slide up and down, and the guide column 3 can ensure smooth and reliable sliding.

[0034] The push mechanism 2 is the driving force source for the pressing plate 4 to slide up and down, and is in the form of a pneumatic cylinder or a hydraulic cylinder. It can provide a smooth and powerful driving force, and is suitable for application scenarios that require greater pressure to stabilize the cardboard. Pneumatic systems are usually low-cost and easy to maintain, while hydraulic systems can provide higher force output and are suitable for heavy-duty operations. The end of the cylinder is fixed to the frame 1, and the end of the piston rod is connected to the pressing plate 4. When the push mechanism is working, it can drive the pressing plate to move up and down to achieve compression or release of the cardboard.

[0035] The guide column 3 is arranged on both sides of the push mechanism 2, playing the role of guidance and support. One end is fixed to the pressure plate 4, and the other end is connected to the frame 1 through the sliding sleeve and slides, ensuring the straightness and stability of the pressure plate during the up and down movement, avoiding deflection or shaking, and improving the accuracy and durability of the equipment operation. The existence of the sliding sleeve reduces friction, making the entire sliding process smoother and more efficient.

[0036] Preferably, the telescopic tooth plate 5 includes a first tooth plate 501 and a second tooth plate 502 that mesh with each other, and a plurality of slots are provided at the ends of the first tooth plate 501 and the second tooth plate 502, and the first tooth plate 501 and the second tooth plate 502 are engaged with each other through the slots. The first tooth plate 501 and the second tooth plate 502 are contracted to form a whole plate, and have uniform slots after being expanded, similar to two comb teeth staggered and engaged.

[0037] The first tooth plate 501 and the second tooth plate 502 are designed to mesh with each other to achieve the telescopic function. A plurality of slots are provided at the end of each tooth plate, and the design of these slots allows the first tooth plate 501 and the second tooth plate 502 to be staggered and connected together like a comb. When it is necessary to expand the clamping range to accommodate a wider cardboard, the tooth plates are separated from each other through the slots to form an extended surface with uniform spacing, similar to staggered comb teeth, which increases the contact area and ensures the uniformity of the pressure applied to the cardboard.

[0038] The telescopic tooth plate 5 is unfolded to a required width to meet the needs of cardboards of different sizes, which greatly improves the versatility and convenience of the equipment.

[0039] Preferably, the first tooth plate 501 and the second tooth plate 502 are provided with through grooves on their sides, and a plurality of sliding pins 11 are provided in the through grooves;

[0040] A plurality of ear plates 401 are fixed on both sides of the pressure plate 4, and both ends of the pin shaft 11 are fixed on the ear plates 401. The first tooth plate 501 and the second tooth plate 502 are slidably extended by the pin shaft 11, and each first tooth plate 501 has at least two pin shafts 11, and the pin shafts 11 are arranged at both ends of the first tooth plate 501, and both ends of the pin shaft 11 are locked on the ear plates 401 by nuts.

[0041] The sides of the first tooth plate 501 and the second tooth plate 502 are provided with through grooves, which are designed to accommodate the sliding pins 11. The pins 11 are used to connect the tooth plates with the pressing plate 4, so that the tooth plates are slidably extended against the pressing plate 4.

[0042] At least two pins 11 are configured in each first tooth plate 501, and these pins are arranged at both ends of the tooth plate. Such a layout can ensure that when the telescopic tooth plate is unfolded, it remains parallel and evenly opened without distortion or asymmetry. Both ends of the pin are locked on the ear plate 401 by nuts. Such a locking mechanism ensures that the position of the pin is fixed during operation, preventing it from falling off or slipping, and enhancing the safety and reliability of the entire device.

[0043] Preferably, the side baffle 6 has two sides with slide grooves, and the ends of the telescopic tooth plate 5 are fixed with sliders, which slide against the slide grooves. The ends of the telescopic tooth plate 5 slide against the slide grooves on the side baffle 6 through the sliders, thereby pressing the cardboard.

[0044] Preferably, through grooves are provided on both sides of the placement platform 7, and both sides of the bottom of the side baffle 6 slide against the through grooves, and a sliding mechanism 8 is provided between the side baffle 6 and the placement platform 7, and the side baffle 6 slides against the placement platform 7 through the sliding mechanism 8. The sliding mechanism 8 is a slide rail and a slider, the slide rail is fixed on the placement platform 7, and the slider is fixed on the side baffle 6, and the side baffle 6 slides against the placement platform 7 through the sliding mechanism 8 more smoothly and reliably.

[0045] Preferably, both ends of the bidirectional screw rod 9 are supported on the bottom of the placement platform 7 through bearing seats for rotation, and a motor 10 connected to the bidirectional screw rod 9 is provided in the middle part thereof, and the motor 10 is connected to the bidirectional screw rod 9 through a gear chain for driving;

[0046] The two ends of the bidirectional screw rod 9 are threadedly connected to the side baffle 6 through the thread sleeve, and the threads at the two ends of the bidirectional screw rod 9 are in opposite directions. The motor 10 drives the bidirectional screw rod 9 to rotate, thereby driving the side baffles 6 on both sides to move relative to each other, and the movement of the side baffles 6 also drives the expansion and contraction of the telescopic tooth plate 5.

[0047] The bidirectional screw 9 is fixed to the bottom of the placement platform 7 through a bearing seat. This design ensures the stability of the screw when rotating and reduces friction. The middle of the screw is connected to the motor 10, which is connected to it through a gear chain transmission system. This design improves the transmission efficiency, so that the power of the motor can be efficiently and stably transmitted to the screw to drive it to rotate.

[0048] The two ends of the bidirectional screw rod 9 are threadedly connected with the side baffle 6 through the thread sleeve, and the threads of the screw rods at both ends are opposite. When the motor drives the screw rod to rotate, the baffles on both sides move relative to each other, so as to achieve the purpose of adjusting the width.

[0049] The movement of the side baffle 6 is not only the expansion or contraction of the side baffle itself, but also directly affects the telescopic tooth plate 5. Since the end of the telescopic tooth plate 5 is connected to the side baffle 6 through the slider, the movement of the side baffle will drive the telescopic tooth plate to expand or contract together, thereby adjusting the pressing width of the cardboard, ensuring that the pressing and positioning of the cardboard are still accurate during the entire width adjustment process.

The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
