Technical Field
[0001] This utility model relates to the technical field of guide components for foldable gift box forming machines, specifically a guide component for a foldable gift box forming machine. Background Technology
[0002] Paper box forming machines are indispensable equipment in paper box production. They can automatically feed the face paper, apply glue to the face paper, automatically convey the cardboard, form the cardboard and attach the four corners, position and glue, and complete the paper box forming process in one go. The whole machine operates in a fully automated, online manner, which greatly improves production efficiency compared to traditional processes. At present, the application prospects of paper box packaging are very optimistic. The market share of paper box packaging is growing in cigarettes, alcohol, food, pharmaceuticals, small household appliances, cosmetics, etc., all of which require exquisite paper box packaging. Therefore, paper box forming machines have good development potential.
[0003] Currently, Chinese patent CN210617440U discloses a guiding mechanism in a packaging box forming machine, including a fixed guide plate and an extension mechanism. The extension mechanism includes a movable guide plate, which is installed at the top of the fixed guide plate. The movable guide plate and the outer wall of the fixed guide plate are fixedly connected by a hinge. Square grooves are formed on the inner surfaces of both the fixed and movable guide plates. Fixed rods are fixedly connected to the inner walls of both ends of the square grooves. Bearings are fixedly connected to the outer surfaces of the fixed rods, and cotton sleeves are fixedly connected to the outer surfaces of the bearings. By designing the movable guide plate, fixed rods, bearings, and cotton sleeves, the problem of existing guiding mechanisms having constant dimensions and being unable to meet the needs of modern and diversified production is solved. The movable guide plate expands the height of the guiding mechanism, enabling it to adapt to the guiding needs of packaging boxes of different sizes, and the cotton sleeves can effectively prevent the packaging boxes from colliding with the guiding mechanism.
[0004] The guiding mechanism in the aforementioned packaging box forming machine still has some problems in use. Although it can adapt to the guiding needs of packaging boxes of different specifications, and the cotton sleeve can effectively prevent the packaging box from colliding with the guiding mechanism, manual feeding is used. Manual feeding generally has the problems of low efficiency and high labor costs. Especially in large-scale production, manual operation is prone to fatigue and errors, which can lead to interruption of the production rhythm. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This utility model integrates the storage and transportation of gift box raw materials by setting up a storage pipe, an electric push rod, and a push block. The storage pipe is installed at the input end of the conveyor belt, thereby improving the efficiency of raw material supply. At the same time, the sliding connection between the L-shaped plate and the push block, together with the electric push rod drive, forms a stable pushing structure, ensuring that the raw materials can be pushed out of the storage pipe to the conveyor belt accurately and orderly, avoiding manual intervention and improving the degree of automation and production efficiency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-4 This embodiment provides a guide component for a foldable gift box forming machine, including a conveyor belt. A storage tube for storing gift box raw materials is installed at the input end of the conveyor belt. L-shaped plates are fixedly connected to both sides of the lower opening of the storage tube, with the openings of the two sets of L-shaped plates facing each other. A push block is slidably connected between the lower ends of the two sets of L-shaped plates. An installation strip is fixedly installed on the back of the storage tube, and an electric push rod is fixedly installed on the back of the installation strip. The telescopic end of the electric push rod passes through the installation strip and is fixedly connected to the end of the push block. An abutment is provided on the top of the push block. Through the arrangement of the storage tube, the electric push rod, and the push block, the storage tube is installed at the input end of the conveyor belt, realizing the integration of gift box raw material storage and conveying, improving raw material supply efficiency. Simultaneously, the sliding connection between the L-shaped plates and the push block, combined with the electric push rod drive, forms a stable pushing structure, ensuring that the raw materials can be accurately and orderly pushed from the storage tube to the conveyor belt, avoiding manual intervention and improving automation and production efficiency.
[0030] The abutment includes a square groove on the top of the push block. A round rod is rotatably connected to the right side of the square groove. Fixed rings are fixedly connected to both ends of the round rod. Push bars are fixedly connected to the tops of the two sets of fixed rings. When the telescopic end of the electric push rod moves forward, the push bar pushes out the bottom set of gift box raw materials inside the storage tube. When the push block retracts, the push bar flips down and is stored inside the push block. Through the setting of the abutment, the abutment adopts a flip-up push bar design. When the electric push rod pushes the push block, the push bar pushes out the raw materials horizontally, and the action is smooth. When the push block retracts, the push bar flips down and is stored in the square groove, which effectively avoids interference between the push bar and the raw materials in the storage tube during the return stroke, ensuring the smoothness of the push block's reciprocating motion, while reducing equipment wear and extending service life.
[0031] A fixing clip is fixedly connected to the inner right wall of the square groove. A connecting ring is fixedly sleeved in the middle of the round rod. A hook is fixedly connected to the top of the connecting ring. A tension spring is sleeved on the surface of the fixing ring. The other end of the tension spring is hung on the surface of the hook. The tension spring allows the push bar to remain horizontal when not in operation, ensuring the stability of the push bar position during material pushing and preventing the material from shifting or falling due to push bar wobbling. Furthermore, the tension spring has a simple structure, is easy to install and maintain, and can reliably realize the push bar's reset function.
[0032] The backs of the two sets of push bars are respectively connected with ball bearings. The ball bearings reduce wear between the push bar and the surface of the raw material, protect the appearance quality of the raw material, and improve the finished product qualification rate.
[0033] The two ends of the right inner wall of the square groove are fixedly connected to abutment pieces. The other ends of the two sets of abutment pieces abut against the back of the corresponding push bar. By setting the abutment pieces, the abutment pieces on the inner wall of the square groove precisely limit the rotation angle of the push bar, ensuring that the push bar is accurately positioned in the storage and working state, preventing the push bar from rotating excessively and affecting the operation of the equipment. At the same time, the abutment pieces can buffer the impact force when the push bar rotates, further improving the stability and reliability of the equipment operation.
[0034] The abutment plate can be made of polyurethane, rubber, or plastic, or a combination of these materials.
[0035] Limiting plates are provided on the inner walls of both sides of the storage tube. The upper ends of the two sets of limiting plates are bent upwards to the corresponding sides. U-shaped frames are provided on both sides of the storage tube. The two ends of the two sets of U-shaped frames pass through the corresponding side storage tube and are fixedly connected to the surface of the corresponding side limiting plate. The ends of the two sets of U-shaped frames are threaded with hand-tightening bolts. The ends of the two sets of hand-tightening bolts pass through the surface of the corresponding side U-shaped frames and are fixedly connected with adapter rods. The two sets of adapter rods are rotatably inserted into the end surface of the corresponding side limiting plate. Through the setting of hand-tightening bolts, the limiting plates and their bending structure on both sides of the storage tube can effectively limit the material of the gift box, preventing the material from shaking or tipping in the storage tube. In addition, the adjustment mechanism composed of U-shaped frames, hand-tightening bolts and adapter rods can flexibly adjust the position of the limiting plates to adapt to the storage and pushing needs of material of different sizes of gift boxes, improving the versatility and applicability of the equipment.
[0036] Both sets of U-shaped frames have strip-shaped grooves extending along their length on their tops. A scale strip is fixedly connected to the inner cavity of each of the two sets of strip-shaped grooves. The scale strip is used to indicate the adjustment position of the limit plate to accommodate raw materials of different sizes of gift boxes. The scale strip provides operators with an intuitive reference for adjusting the limit plate, making the adjustment process more convenient and precise. It allows for quick adaptation to raw materials of different sizes without complex measurements, shortening equipment debugging time, improving production preparation efficiency, and meeting diverse production needs.
[0037] Guide strips are fixedly connected to both sides of the push block, and guide grooves for the guide strips to slide are opened at the opposite ends of the two sets of L-shaped plates. Through the setting of guide strips and guide grooves, the cooperation between the guide strips on both sides of the push block and the guide grooves of the L-shaped plates provides precise guidance for the sliding of the push block, effectively preventing the push block from deviating or getting stuck during the sliding process, ensuring the smoothness and accuracy of the push block's movement, thereby ensuring the accuracy of the raw material pushing position and improving the stability and reliability of the overall equipment operation.
[0038] Working principle;
[0039] First, the gift box materials are neatly stacked and stored in the storage tube. The L-shaped plates fixed on both sides of the lower opening of the storage tube provide track support for the sliding of the push block, and at the same time, prevent the gift box materials from falling out.
[0040] In the initial state, the push block is located at the starting position at the lower end of the L-shaped plate. The push bar in the square groove at the top of the push block is kept horizontal under the action of the tension spring. One end of the tension spring is sleeved on the surface of the fixing ring, and the other end is hung on the hook at the top of the connecting ring. The connecting ring is fixedly sleeved in the middle of the round rod. The round rod is rotatably connected to the inside of the right side of the square groove. The fixing rings at both ends are respectively connected to the push bar.
[0041] When the telescopic end of the electric push rod extends forward, it drives the push block to slide forward along the guide groove on the L-shaped plate. The push bar at the top of the push block is kept horizontal due to the tension of the tension spring, which smoothly pushes the bottom set of gift box raw materials in the storage tube to the input end of the conveyor belt, and then conveys them to the feed port of the gift box forming machine through the conveyor belt.
[0042] When the telescopic end of the electric push rod retracts, causing the push block to slide backwards, the push bar, under the contact and compression with the inner wall of the storage tube or the remaining raw material, overcomes the tension of the tension spring, rotates downwards around the round rod in the square groove, and gradually retracts into the push block. Furthermore, the rolling ball connected to the back of the push bar greatly reduces the friction between the push bar and the gift box raw material.
[0043] When the pusher moves to the initial position, the top of the push bar disengages from the bottom of the gift box material, and the tension spring retracts, thereby causing the push bar to rotate in a circular motion. The back of the push bar abuts against the end of the abutment piece to prevent the push bar from rotating excessively.
[0044] Furthermore, when processing gift box materials of different sizes, the adapter rod can be rotated by turning the hand-tightening bolt at the end of the U-shaped frame, causing the U-shaped frame to move axially along the hand-tightening bolt, thereby driving the limiting plate fixedly connected to it to move synchronously, realizing flexible adjustment of the position of the limiting plate, thus making it suitable for gift box materials of different sizes.
[0045] The scale strip fixed in the strip groove set along the length of the top of the U-shaped frame provides operators with an intuitive reference, making it easy to accurately adjust the position of the limiting plate according to the raw materials of different sizes of gift boxes, ensuring that the raw materials are placed stably in the storage tube and meeting diverse production needs.
[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
