Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, specifically a folding machine for producing packaging cardboard boxes. Background Technology

[0002] Packaging cartons are indispensable packaging containers for the transportation and storage of goods. They are usually made of corrugated cardboard, which is made of face paper, liner paper and corrugated core paper bonded together. It has good compression resistance and shock resistance. Its appearance is generally rectangular, with a regular structure, which makes it easy to stack and save storage and transportation space. Various patterns and texts can be printed on the surface of packaging cartons, which can not only display product information and brand logos, playing a role in publicity and promotion, but also indicate precautions. Moreover, it is low in cost, recyclable and reusable, in line with the concept of environmental protection, and is widely used in the packaging of goods in many industries such as food, home appliances, and daily necessities.

[0003] Folding machines are needed in the production of cardboard boxes because they can efficiently complete the folding and forming process. Traditional folding is inefficient and lacks precision, while folding machines can quickly and accurately fold flat cardboard into the required shape, ensuring standard box dimensions and a stable structure. This significantly improves production efficiency and product quality, meeting the needs of large-scale production. However, existing folding machines for cardboard box production lack the necessary adjustment mechanisms. They are unable to adapt to changes in box size and shape. When folding large or small boxes with special shapes, the machine cannot make the corresponding adjustments, leading to deviations in the folding process, affecting the forming quality of the boxes, and even potentially causing damage. This not only reduces production efficiency but also increases production costs, making it difficult to meet diverse production needs.

[0004] Therefore, it is necessary to provide a new folding machine for producing packaging cartons to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a folding machine for producing packaging cartons, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a folding machine for producing packaging cartons, including a support frame, and further comprising:

[0007] A support plate is fixed to the top of the support frame, and a top plate is fixed to the top of the support plate, and a drive assembly is fixed to the top of the top plate.

[0008] A connecting plate is fixed to one side of a support plate, a fixing plate is fixed to one side of the connecting plate, and a positioning plate is fixed to the top of the fixing plate;

[0013] Preferably, a chain is engaged with the outer side of the sprocket, and a roller for transporting the carton is fixed to the inner wall of the sprocket.

[0014] Preferably, a support rod is fixed to one side of the positioning plate, and a sliding rod is slidably connected to the inner wall of the support rod, with one end of the sliding rod fixed to one side of the limiting plate.

[0015] Preferably, the bottom of the support frame is fixed with a fixing frame, and the fixing frame is fixed with an orientation plate for supporting the main body.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features an adjustment component that drives a limiting plate to the required distance. The limiting plate, in turn, causes a sliding rod to slide along the inner wall of the support rod.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-4 As shown, a folding machine for producing packaging cartons includes a support frame 1 and a support plate 2. The support plate 2 is fixed to the top of the support frame 1, the top plate 3 is fixed to the top of the support plate 2, and the drive assembly 4 is fixed to the top of the top plate 3. The design of the support frame 1 makes it easy to fix the support plate 2, the design of the support plate 2 makes it easy to fix the top plate 3, and the design of the drive assembly 4 makes it easy to press down the cartons, thus avoiding the problems of low efficiency and poor precision of traditional folding.

[0025] The connecting plate 5 is fixed to one side of the support plate 2. A fixing plate 6 is fixed to one side of the connecting plate 5. A positioning plate 7 is fixed to the top of the fixing plate 6. The support plate 2 can fix the fixing plate 6 through the connecting plate 5. The fixing plate 6 has a groove. The design of the fixing plate 6 allows the folded carton to fall through the groove, which facilitates the subsequent transportation of the folded carton and improves the convenience of the device.

[0026] The adjustment component 8 is located inside the positioning plate 7. A limiting plate 9 for folding the carton is fixed on one side of the adjustment component 8. The design of the adjustment component 8 allows the limiting plate 9 to be moved easily, which facilitates the subsequent folding of cartons of different shapes. This avoids the problem that the machine cannot make the corresponding adjustment when it is necessary to fold cartons of large or small size or special shape. There are four sets of limiting plates 9, and the limiting plate 9 is composed of two parts: the upper half is a curved surface and the lower half is a straight surface.

[0027] The drive assembly 4 includes a cylinder 41 fixed to the top of the top plate 3. The piston rod of the cylinder 41 is fixed with a push plate 42 for folding the carton. The top plate 3 can fix the cylinder 41. When the cylinder 41 is opened, the push plate 42 is driven by the cylinder 41 to press down and fold, which facilitates the subsequent pressing and folding of the carton and improves the convenience of the device. The cylinder 41 is existing technology. A compressor is installed outside the cylinder 41. The compressor is a gas source device responsible for compressing and pressurizing air or other gases, storing them in a gas tank, and providing high-pressure gas. The cylinder 41 is an actuator that uses compressed gas to drive the piston to make linear motion and complete the mechanical action.

[0028] The adjustment assembly 8 includes a threaded rod 81 threadedly connected to the inner wall of the positioning plate 7. One end of the threaded rod 81 is fixed to a turntable 82, and the other end of the threaded rod 81 is rotatably connected to one side of the limiting plate 9. By rotating the turntable 82, the threaded rod 81 is driven to rotate, so that the threaded rod 81 rotates along the threaded inner wall of the positioning plate 7, thereby moving the limiting plate 9 to the required distance. This achieves the effect of folding cartons of different shapes and avoids the problem that the machine cannot make corresponding adjustments when it is necessary to fold cartons of large or small size or special shape.

[0029] A motor 10 is fixed on one side of the support frame 1, and a sprocket 11 is fixed at the output end of the motor 10. The motor 10 can be fixed by the support frame 1. There are four sets of sprockets 11. One set of sprockets 11 is fixed at the output end of the motor 10. When the motor 10 is turned on, the sprockets 11 are driven to rotate, which facilitates the subsequent transportation of the folded carton and improves the convenience of the device.

[0030] A chain 12 is meshed with the outer side of the sprocket 11, and a roller 13 for conveying the carton is fixed to the inner wall of the sprocket 11. When the motor 10 is turned on, a set of sprockets 11 are driven to rotate, which in turn drives the chain 12 to rotate, and the chain 12 drives the other three sets of sprockets 11 to rotate, so that the sprockets 11 drive the roller 13 to rotate. This facilitates the subsequent conveying of the folded carton and improves the convenience of the device.

[0031] A support rod 14 is fixed to one side of the positioning plate 7. A slide rod 15 is slidably connected to the inner wall of the support rod 14, and one end of the slide rod 15 is fixed to one side of the limiting plate 9.

[0032] A fixing frame 16 is fixed to the bottom of the support frame 1. The fixing frame 16 is fixed with an directional plate 17 for supporting the main body. The directional plate 17 can support the support frame 1 through the fixing frame 16, which improves the stability of the device during use.

[0033] Working Principle: When using this device, the operator first rotates the turntable 82 to fold the cardboard box as needed. The turntable 82 drives the threaded rod 81 to rotate, which in turn moves the limiting plate 9. The limiting plate 9 then moves the sliding rod 15 along the inner wall of the support rod 14, facilitating subsequent adjustment of the distance using the limiting plate 9 and improving the device's stability. Rotating the turntable 82 drives the threaded rod 81 to rotate, which in turn moves the limiting plate 9 to the required distance along the threaded inner wall of the positioning plate 7. The cardboard box is then placed on the arc surface of the four sets of limiting plates 9, and the cylinder 41 is activated. The cylinder 41 drives the push plate 42 to press down the carton, thereby achieving the effect of folding cartons of different shapes. This avoids the problem that the machine cannot make corresponding adjustments when folding large or small or specially shaped cartons. After folding, the carton will fall straight down onto the roller 13 along the limit plate 9. Then, the motor 10 is turned on, which drives a set of sprockets 11 to rotate. The set of sprockets 11 drives the chain 12 to rotate, and the chain 12 drives the other three sets of sprockets 11 to rotate. This causes the sprockets 11 to drive the roller 13 to rotate, thus conveying the folded carton.
