Description

Technical Field

[0001] This utility model relates to a range hood accessory, specifically an embedded range hood mounting clip. Background Technology

[0002] In motor manufacturing, slot paper is a common insulating material, typically used for insulation of the motor stator or rotor. The forming and insertion of slot paper are crucial steps in motor manufacturing, significantly impacting the motor's operational reliability. Currently, in slot paper processing, folding and insertion are often performed independently, and many existing equipment methods have significant shortcomings in achieving these functions, affecting production efficiency.

[0003] Existing grooved paper folding technology typically relies on stamping or mechanical folding, which involves cutting the grooved paper to the appropriate size and then folding both sides of the paper using stamping equipment. This stamping folding method has the following drawbacks:

[0004] 1. Low production efficiency: The stamping process requires pre-positioning and clamping of the groove paper, and then completing the folding through mechanical movement. The whole process has a long cycle and is difficult to meet the needs of automated high-speed production.

[0005] 2. Low precision: The stamping and folding method is highly dependent on the material, thickness and folding angle of the groove paper, which can easily lead to deformation or uneven folds in the groove paper, affecting the forming quality of the groove paper.

[0006] 3. High equipment wear and tear: Stamping equipment needs to withstand high pressure during the bending operation, which can easily cause wear and tear over a long period of time, increasing maintenance and replacement costs.

[0007] Furthermore, existing paper feeding mechanisms typically only transport the tray paper and cannot perform edge folding during transport. The transport method for the tray paper within the feeding mechanism is relatively simple, usually using rollers or belt drives, lacking an edge folding mechanism. Therefore, a separate edge folding process is still required. In this traditional production process, the tray paper needs to be transported and positioned multiple times, which presents the following problems:

[0008] 1. Complex process and high labor intensity: The folding and conveying of the grooved paper are two separate processes, which require operators to repeatedly position and adjust. The process is complex and tedious, which increases the labor intensity of production.

[0009] 2. High difficulty in equipment coordination: Due to the independent nature of the paper folding and conveying equipment, additional robotic arms or conveyor belts are required for connection, increasing the difficulty of coordination and control between the equipment. Even slight errors can lead to deviations in the folding or insertion of the paper. Therefore, further improvements are necessary. Utility Model Content

[0010] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide an improved automatic folding and feeding device for grooved paper that is simple in structure and easy to use. This utility model innovatively integrates the folding mechanism into the paper feeding mechanism, so that the grooved paper can be folded during the conveying process, which greatly simplifies the process and improves the production efficiency.

[0011] The purpose of this utility model is achieved through the following means: a feeding mechanism for an automatic slotted paper feeding machine, which includes a main unit, a paper feeding tray installed on one side of the main unit, and slotted paper to be processed is placed in the paper feeding tray;

[0012] It also includes a paper folding mechanism at the bottom of the main unit. The paper folding mechanism includes a base and a panel covering its surface. The base is provided with a paper guide groove and a paper folding groove. The paper passes through the paper guide groove and enters the paper folding groove, and the edges of the paper are bent on both sides of the paper.

[0013] It also includes a paper feeding mechanism that is connected to the folding mechanism. The paper feeding mechanism includes a first roller and a second roller that are mounted opposite each other. The first roller and the second roller are clamped at the front and rear ends of the slotted paper. The first roller and the second roller are driven to rotate by a paper feeding motor.

[0014] It also includes a shaping block that docks with the paper feeding mechanism. The shaping block has a shaping groove inside, and the grooved paper moves inside the shaping groove, feeding the shaped grooved paper into the grooved paper injection mechanism above it.

[0015] Furthermore, the inlet end of the folding groove is provided with a folding baffle, which is inclined from the outside to the inside.

[0016] Furthermore, the folding groove is flared in shape, with a wider inlet end and a narrower outlet end.

[0017] Furthermore, the first roller and the second roller are mounted on the folding base via a rotating shaft, and the first roller and the second roller are equipped with a first gear and a second gear that mesh with each other.

[0018] Furthermore, a pulley is also installed on the rotating shaft, and the pulley is connected to the paper feeding motor via a transmission belt.

[0019] Furthermore, the paper feeding motor is a servo motor.

[0020] Furthermore: the first roller is a metal roller and the second roller is a rubber roller.

[0021] Furthermore, the first roller is a rubber roller and the second roller is a metal roller.

[0022] Furthermore: the first roller and the second roller metal wheel.

[0023] Furthermore: the first roller and the second roller rubber wheel.

[0024] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness.

[0025] 2. This utility model integrates a folding mechanism into the paper feeding mechanism, allowing the folding of both sides of the grooved paper to be completed during the feeding process, eliminating the need for a separate stamping and folding process. This effectively improves production efficiency and reduces the complexity of the operation process. This integrated design simplifies the grooved paper processing technology, significantly improves the degree of automation, and reduces the need for manual intervention.

[0026] 3. Traditional stamping and folding methods easily lead to deformation and uneven creases in the folded paper. This invention, however, uses a combination of a guide groove and a folding groove, with rollers clamping and feeding the paper, resulting in a smoother and more precise folding process. Furthermore, the inclined design of the folding baffle ensures the paper is smoothly guided as it enters the folding groove, reducing wear and extending the equipment's lifespan, while also making the paper movement smoother and more stable.

[0027] 4. This utility model achieves a more compact overall structure and higher stability by rationally arranging key components such as rollers, gears, and pulleys. Using a servo motor to drive the rollers and control paper feeding not only ensures the accuracy of paper feeding but also facilitates maintenance, reduces operational complexity, helps reduce failure rates, and improves production continuity.

[0028] 5. The claims specify various combinations of metal and rubber wheels to meet the processing requirements of different groove paper materials. For example, the combination of metal and rubber wheels can achieve better friction and a smoother paper clamping effect. This flexibility in material combination allows the equipment to adapt to diverse groove paper types, enhancing its versatility. Attached Figure Description

[0036] The present invention will be further described in detail below with reference to the accompanying drawings. A feeding mechanism for an automatic slotted paper feeding machine includes a main unit 1, a paper feeding tray 2 installed on one side of the main unit 1, and the slotted paper to be processed is placed into the paper feeding tray 2;

[0037] It also includes a paper folding mechanism 3 located at the bottom of the main unit 1. The paper folding mechanism 3 includes a base 31 and a panel 32 covering its surface. The base 31 is provided with a paper guide groove 33 and a paper folding groove 34. The paper passes through the paper guide groove 33 and enters the paper folding groove 34. The retaining edges 41 are bent on both sides of the paper 4.

[0038] It also includes a paper feeding mechanism 5 that is connected to the folding mechanism 3. The paper feeding mechanism 5 includes a first roller 51 and a second roller 52 that are mounted opposite each other. The first roller 51 and the second roller 52 are clamped at the front and rear ends of the slotted paper. The first roller 51 and the second roller 52 are driven to rotate by the paper feeding motor 53.

[0039] It also includes a shaping block 6 that docks with the paper feeding mechanism 5. The shaping block 6 has a shaping groove 61 inside. The grooved paper moves inside the shaping groove 61 and is fed into the grooved paper feeding mechanism 7 above it.

[0040] In one embodiment: a folding baffle 35 is provided at the entrance end of the folding groove 34, and the folding baffle 35 is inclined from the outside to the inside.

[0041] In one embodiment, the folding groove 34 is arranged in a trumpet shape, with a wider inlet end and a narrower outlet end.

[0042] In one embodiment: the first roller 51 and the second roller 52 are mounted on the folding base 54 via a rotating shaft, and the first roller 51 and the second roller 52 are equipped with a first gear and a second gear that mesh with each other.

[0043] In one embodiment: a pulley 55 is also installed on the rotating shaft, and the pulley 55 is connected to the paper feeding motor 53 via a transmission belt.

[0044] In one embodiment, the paper feeding motor 53 is a servo motor.

[0045] In one embodiment: the first roller 51 is a metal roller and the second roller 52 is a rubber roller.

[0046] In one embodiment: the first roller 51 is a rubber roller and the second roller 52 is a metal roller.

[0047] In one embodiment: the first roller 51 and the second roller 52 are metal wheels.

[0048] In one embodiment: the first roller 51 and the second roller 52 are rubber wheels.

[0049] Working principle: The feeding mechanism of this utility model first completes the feeding operation of the grooved paper through the paper feeding tray 2 installed on one side of the main unit 1. The grooved paper to be processed is placed in the paper feeding tray 2, ready to enter the next processing step. The paper feeding tray is reasonably designed, which facilitates the operator in feeding the paper and improves the convenience of operation.

[0050] The paper is fed from the paper feed tray 2 into the folding mechanism 3 at the bottom of the main unit. The folding mechanism 3 consists of a base 31 and a panel 32 covering the surface of the base. The base is equipped with a guide groove 33 and a folding groove 34. Before entering the folding groove 34, the paper is first guided by the guide groove 33 to ensure a smooth entry and prevent the paper from shifting or wrinkling during movement. The design of the guide groove 33 not only effectively maintains the position of the paper but also reduces friction and improves the smoothness of paper transport.

[0051] After passing through the guide groove, the paper enters the folding groove 34, where an inwardly inclined folding baffle 35 is installed at the entrance. This baffle design allows the paper to be smoothly folded upon entering the folding groove, forming curved baffle edges 41 on both sides. This automated folding method is more stable than traditional stamping folding, preventing deformation of the paper edges, reducing impact, minimizing equipment wear, and extending the equipment's service life.

[0052] The folded paper enters the paper feeding mechanism 5, which includes a first roller 51 and a second roller 52 mounted opposite each other. The first and second rollers are driven to rotate by a paper feeding motor 53. The two rollers clamp the front and rear ends of the paper, ensuring stability during transport and preventing slippage or positional deviation. This clamping and conveying method ensures accurate paper delivery while reducing operational complexity and enhancing the equipment's automation level.

[0053] The materials of the first and second rollers in the paper feeding mechanism can be flexibly adjusted according to processing requirements. A combination of metal or rubber rollers can be selected to achieve optimal clamping effect and friction on various types of grooved paper. This diverse material combination enhances the equipment's applicability, enabling it to adapt to a wider variety of grooved paper types.

[0054] As the paper, held by the feeding mechanism, continues to move forward, it enters the shaping block 6. The shaping block contains a shaping groove 61, within which the paper moves. This mechanism further shapes the paper, ensuring it remains flat before entering the next insertion mechanism 7. The function of the shaping block is to eliminate any folds or minor unevenness in the paper during transport, bringing it to its optimal state and ensuring accurate insertion into the motor slot, thus improving the quality of the finished product.

[0055] Finally, the shaped slotted paper is fed into the slotted paper insertion mechanism 7 above it. The insertion mechanism completes the final shaping and insertion of the slotted paper, achieving precise alignment between the slotted paper and the motor stator or rotor, thus completing the entire slotted paper forming and installation process. Because the slotted paper maintains precise position control in each stage of conveying, folding, and shaping, the operation of the insertion mechanism is more efficient and accurate, reducing the risk of slotted paper misalignment.

[0056] Compared with traditional technologies, this invention enables the simultaneous completion of groove paper folding during the paper feeding process, which greatly improves the automation level of groove paper forming and avoids the inefficiency and easy wear problems of traditional stamping and folding.

[0057] Meanwhile, the roller clamping method not only makes the transmission of the grooved paper more stable, but also has strong adaptability to different roller combinations. Metal or rubber materials can be selected according to actual production needs to ensure precise control of the grooved paper during transmission.

[0058] In summary, the feeding mechanism of the automatic slotted paper feeding machine of this utility model not only simplifies the slotted paper forming process, but also improves production efficiency and equipment reliability, and is suitable for automated applications in the mass production of motor slotted paper.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
