Description

Technical Field

[0001] This utility model relates to the technical field of loading and unloading devices, specifically a loading and unloading device with a cutting function. Background Technology

[0002] In the processing and production of soft strip materials such as rubber strips and silicone strips, the material needs to be conveyed and cut to a fixed length through loading and unloading devices to meet the size requirements of subsequent assembly and processing. The core requirements are to ensure the stability and cutting accuracy during the material conveying process, while avoiding damage to the surface of the soft material.

[0003] Existing loading and unloading devices typically use a flat conveyor belt with straight guide plates on both sides for material transport. The conveyor belt is driven by a motor to move the material forward, and after reaching the designated position, the cutting blade is driven by a cylinder to complete the cutting.

[0004] However, when using this device, the surface of soft strip materials is smooth, and the contact method between the flat conveyor belt and the straight guide plate results in insufficient friction, which easily leads to slippage and deviation during material transportation, thus affecting the cutting accuracy. In view of this, we propose a loading and unloading device with cutting function. Utility Model Content

[0005] The purpose of this invention is to provide a loading and unloading device with a cutting function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a loading and unloading device with cutting function, including a conveyor frame, a driving mechanism provided on the side wall of the conveyor frame, a conveyor belt provided on the inner wall of the conveyor frame, a bracket fixedly installed on the upper end of the conveyor frame, a first electric push rod fixedly installed on the upper end of the bracket, the output shaft of the first electric push rod passing through the side wall of the bracket and fixedly installed with a cutting seat, a cutting blade fixedly installed on the lower end of the cutting seat, and a guide structure provided on the upper end of the conveyor frame;

[0007] The guide structure includes two sets of first baffles fixedly installed on both sides of the upper end of the conveyor frame. One end of the second baffle is fixedly installed on the side wall of the first baffle, and a correction plate is fixedly installed on the other end of the second baffle. The correction plate has a V-shaped groove on its side wall, and an arc-shaped pad is fixedly installed on the side wall of the V-shaped groove. An opening is opened in the middle of the arc-shaped pad, and multiple sets of anti-slip pads are fixedly installed on the surface of the arc-shaped pad.

[0008] Preferably, the guide structure further includes multiple sets of through grooves formed on the side wall of the V-shaped groove, one end of a miniature spring is fixedly installed on the inner wall of the through groove, a slide plate is fixedly installed on the other end of the miniature spring, and an elastic pin is fixedly installed on the side wall of the slide plate.

[0009] Preferably, the inner wall of the through groove is slidably connected to the slide plate, and the end of the elastic pin away from the through groove is set with an arc-shaped structure, which can avoid the sharp end from scratching the surface of soft materials, while increasing the contact area with the material and improving positioning stability.

[0010] Preferably, one end of the arc-shaped structure of the elastic ejector pin is located outside the through groove, and the position of the opening matches the position of the through groove, providing a smooth extension channel for the elastic ejector pin and avoiding interference with the arc-shaped pad.

[0011] Preferably, multiple sets of the anti-slip pads are distributed on both sides of the opening and face opposite directions. The surface of the correction plate has multiple sets of exhaust holes, which can promptly discharge the air generated by the material and the arc-shaped pad, break the negative pressure adsorption, and avoid conveying jams.

[0012] Preferably, a second electric push rod is fixedly installed on the upper end of the bracket, and the lower end of the output shaft of the second electric push rod passes through the side wall of the bracket and is fixedly installed with a limit plate. A collection box is fixedly installed on the side wall of the conveyor frame. The collection box can hold the cut materials and improve the convenience of unloading.

[0013] Preferably, two sets of guide ribs are fixedly installed on the side wall of the correction plate, and multiple shallow grooves are formed on the surface of the guide ribs.

[0014] Compared with the prior art, the present invention provides a loading and unloading device with cutting function, which has the following beneficial effects:

[0015] 1. This loading and unloading device with cutting function has a guide structure that ensures accurate guidance and correction of the rubber strip during transportation, resulting in high cutting efficiency. The combination of V-groove and arc-shaped pad forms a wrap-around contact, increasing the contact area between the material and the guide structure. Multiple anti-slip pads on the surface enhance friction and prevent slippage and deviation when conveying soft materials. The flexible material of the arc-shaped pad and the arc-shaped end design of the elastic pin prevent rigid contact from scratching the material surface. The elastic pin driven by a micro-spring can adapt to the elastic deformation of the material and achieve positioning through dynamic pressure, preventing the material from being squeezed and deformed, thus facilitating direct cutting.

[0016] 2. The loading and unloading device with cutting function can promptly discharge air from the contact surface by setting vent holes on the surface of the correction plate, breaking the negative pressure adsorption state and preventing conveying jams and poor separation after cutting.

Detailed Implementation

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a loading and unloading device with cutting function, including a conveyor frame 1, a driving mechanism is provided on the side wall of the conveyor frame 1, a conveyor belt is provided on the inner wall of the conveyor frame 1, a bracket 2 is fixedly installed on the upper end of the conveyor frame 1, a first electric push rod 5 is fixedly installed on the upper end of the bracket 2, the output shaft of the first electric push rod 5 passes through the side wall of the bracket 2 and a cutting seat is fixedly installed thereon, a cutting blade 6 is fixedly installed on the lower end of the cutting seat, and a guide structure 3 is provided on the upper end of the conveyor frame 1;

[0024] The guide structure 3 includes two sets of first baffles 31 fixedly installed on both sides of the upper end of the conveyor frame 1. One end of a second baffle is fixedly installed on the side wall of the first baffle 31, and a correction plate 32 is fixedly installed on the other end of the second baffle. A V-shaped groove 33 is formed on the side wall of the correction plate 32. An arc-shaped pad 34 is fixedly installed on the side wall of the V-shaped groove 33. An opening is formed in the middle of the arc-shaped pad 34. Multiple sets of anti-slip pads 35 are fixedly installed on the surface of the arc-shaped pad 34. The guide structure 3 also includes multiple sets of through grooves 36 formed on the side wall of the V-shaped groove 33. A miniature spring 37 is fixedly installed on one end of the inner wall of the through groove 36, and a slide plate is fixedly installed on the other end of the miniature spring 37. An elastic pin 38 is fixedly installed on the side wall of the slide plate. The inner wall of the through groove 36 is slidably connected to the slide plate. The end of the elastic pin 38 away from the through groove 36 is set as an arc-shaped structure. The arc-shaped end of the elastic pin 38 is located outside the through groove 36. The position of the opening matches the position of the through groove 36. Multiple anti-slip pads 35 are distributed on both sides of the opening and face opposite directions. Multiple vent holes 7 are opened on the surface of the correction plate 32.

[0025] In one embodiment of this utility model, the conveyor frame 1, as the core supporting foundation of the entire device, adopts a frame structure design, providing a stable mounting and support carrier for all functional components such as the drive mechanism, conveyor belt, support 2, and guide structure 3. The drive mechanism, as the power source for the operation of the conveyor belt, integrates components such as motor, reducer, transmission wheel, and transmission belt, and is fixed in a dedicated installation area on the side wall of the conveyor frame 1. The conveyor belt is a flexible and wear-resistant conveyor belt, laid on the guide rail on the inner wall of the conveyor frame 1, serving as the direct carrier for material carrying and conveying. The support 2 adopts a vertical rigid support structure, vertically fixed at the upper center of the conveyor frame 1. The first electric push rod 5, as the cutting power execution component, adopts a high-precision linear reciprocating drive structure and is fixed in the dedicated power installation area at the upper end of the support 2. The cutting blade 6 adopts a thin-blade sharp blade design, fixed to the lower end of the output shaft of the first electric push rod 5 through a detachable cutting seat. The blade is straight, ensuring uniform force when in contact with the material, resulting in a smooth and neat cutting surface.

[0026] The limiting plate 8 adopts a flat structure design and is fixed to the lower end of the output shaft of the second electric push rod. It is located directly above the material conveying path directly below the cutting blade 6. The limiting plate 8 restricts the material. The collection box 9 has an open box structure and is fixed to the unloading end of the side wall of the conveyor frame 1, so as to facilitate the user to collect the cut material. The first baffle 31 adopts a straight plate structure and is symmetrically fixed on both sides of the upper end of the conveyor frame 1, forming the first lateral constraint boundary for material conveying. The height of the baffle is adapted to the material conveying height, which can effectively prevent the material from falling off from both sides of the conveyor frame 1 without affecting the normal conveying posture of the material. The second baffle is tilted at a certain angle to further adjust the position of the material and move it to the correction plate 32.

[0027] The calibration plate 32, as the core installation carrier and attitude correction body of the guide structure 3, adopts a block structure design. It is fixedly connected to the first baffle 31 through the second baffle. The installation position is precisely aligned with the material conveying path. The side wall of the calibration plate 32 is precisely machined with V-shaped grooves 33 to provide a close-fitting constraint surface for the material. The V-shaped grooves 33 can form a wrapping constraint on the material from both sides, increasing the contact area between the material and the guide structure 3 and improving the positioning stability. The surface of the groove wall is smooth and flat, without any unevenness, reducing the installation gap with the arc-shaped pad 34 and ensuring that the arc-shaped pad 34 is flat and close after being fixed. The length of the V-shaped groove 33 covers the key area of ​​material guidance, ensuring that the material is always in a constrained state throughout the guiding process and avoiding attitude deviation caused by midway loss of constraint.

[0028] The arc-shaped pad 34 is fixed to the side wall of the V-shaped groove 33. Its arc-shaped surface closely fits the outer contour of the soft strip material, forming a flexible contact. The pad material has both good elasticity and wear resistance, which can not only fit tightly to the material surface and enhance the contact friction, but also avoid the rigid contact from causing scratches and indentations to the material surface. The anti-slip pad 35 is made of a high-friction coefficient elastic material and is uniformly fixed to the surface of the arc-shaped pad 34 in block or strip shape. Multiple sets of anti-slip pads 35 are distributed on both sides of the opening and face opposite directions. The surface of the anti-slip pad 35 has a fine anti-slip texture, which can enhance the frictional resistance with the material surface and form frictional constraints on the material from different directions, effectively suppressing the relative sliding during material conveying. The through groove 36 is opened on the side wall of the V-shaped groove 33 and is evenly distributed, providing installation space and movement stroke for the miniature spring 37, the sliding plate and the elastic pin 38.

[0029] The inner wall of the through groove 36 is machined with a guide groove that precisely matches the slide plate, ensuring that the slide plate drives the elastic pin 38 to slide smoothly back and forth without jamming or deviation. The micro spring 37 adopts a high-precision compression spring structure, with one end fixed to the spring mounting seat on the inner wall of the through groove 36 and the other end rigidly connected to the slide plate, providing continuous and stable elastic pressure for the elastic pin 38. The slide plate adopts a plate-like structure design, which precisely matches the guide groove on the inner wall of the through groove 36 to achieve sliding connection. The surface of the slide plate is smooth and wear-resistant, with low friction when in contact with the inner wall of the groove, ensuring smooth and flexible reciprocating motion. The micro spring 37 is fixed on one side of the slide plate, and the elastic pin 38 is fixed on the other side, which plays a role in force transmission and guidance. It can smoothly transmit the elastic force of the micro spring 37 to the elastic pin 38, while ensuring that the elastic pin 38 always extends and retracts along the axis of the through groove 36, avoiding deflection.

[0030] The elastic ejector pin 38 adopts a rod-shaped structure, with one end fixed to the slide plate and the other end designed as a smooth arc structure. It has a certain rigidity and toughness. When the arc end contacts the surface of soft material, it can increase the contact area and improve the positioning stability, while avoiding the sharp end from scratching or puncturing the material surface. The length design of the elastic ejector pin 38 ensures that one end of its arc structure can extend out of the outside of the through groove 36 and elastically contact the material surface through the opening in the middle of the arc-shaped pad 34. Under the action of the micro spring 37, dynamic adaptive positioning is achieved. The contact pressure can be adjusted in real time according to the slight deformation of the material to avoid the material being squeezed and deformed.

[0031] Please continue reading. Figures 1-5 The upper end of the bracket 2 is fixedly installed with a second electric push rod. The lower end of the output shaft of the second electric push rod passes through the side wall of the bracket 2 and is fixedly installed with a limit plate 8. The side wall of the conveyor frame 1 is fixedly installed with a collection box 9. The side wall of the correction plate 32 is fixedly installed with two sets of guide ribs 10. Multiple shallow grooves 11 are opened on the surface of the guide ribs 10.

[0032] In this embodiment of the invention, the exhaust holes 7 are evenly distributed in a matrix on the surface of the correction plate 32, penetrating the thickness direction of the correction plate 32 and communicating with the interior of the V-shaped groove 33 to form an airflow channel. The inner wall of the channel is smoothed, without burrs or protrusions, to ensure smooth airflow and no airflow obstruction. The guide ribs 10 are long strip-shaped frustum structures, symmetrically fixed to the material outlet end of the side wall of the correction plate 32. The two sets of guide ribs 10 are arranged symmetrically to form a converging guide channel. Their surfaces are polished, smooth and without burrs, to avoid scratching the material surface. The guide surface of the guide ribs 10 is designed as a smooth slope, which can perform secondary posture correction on the material during conveying and further correct the parallelism between the material axis and the conveying direction.

[0033] Shallow grooves 11 are evenly and parallelly opened on the surface of guide ribs 10, extending along the material conveying direction to form a long strip-shaped groove structure. Shallow grooves 11 can increase the contact area between guide ribs 10 and the material surface, improve friction, and further suppress material slippage and deviation. They can also serve as a debris guide channel to guide fine material debris generated during the conveying process to both ends of guide ribs 10 for discharge, thus preventing debris from accumulating between the material and guide ribs 10.

[0034] During operation, soft strip-shaped materials such as rubber strips and silicone strips are first placed on the conveyor belt of the conveyor frame 1. The drive mechanism starts and drives the conveyor belt to run, and the materials move towards the cutting station. When the materials move to the guide structure 3, they will move along the first baffle 31 and the second baffle to the correction plate 32. After the materials enter the V-shaped groove 33, they flexibly fit with the arc-shaped pad 34. Multiple sets of anti-slip pads 35 on the surface of the arc-shaped pad 34 form friction constraints on the materials from different directions. The micro springs 37 in the through groove 36 push the slide plate to drive the elastic pins 38 to extend and pass through the opening in the middle of the arc-shaped pad 34 to elastically contact the surface of the materials, adapting to the elastic deformation of the materials. During the material conveying process, the exhaust holes 7 on the surface of the correction plate 32 hold The air generated when the material comes into contact with the arc-shaped pad 34 is discharged. Then, the guide ridge 10 on the side wall of the correction plate 32 further assists in straightening the material's posture. The multiple shallow grooves 11 on its surface not only increase the contact friction with the material, but also, when the material reaches the preset cutting position, the second electric push rod is activated, and the output shaft drives the limiting plate 8 to descend, which longitudinally limits the material. Then, the first electric push rod 5 is activated, and the output shaft pushes the cutting seat and the cutting blade 6 to descend, which cuts the material to a fixed length. After the cutting is completed, the first electric push rod 5 and the second electric push rod respectively drive the cutting blade 6 and the limiting plate 8 to reset. The cut material continues to move with the conveyor belt and finally falls into the collection box 9 on the side wall of the conveyor frame 1, completing the unloading and storage.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
