Description

Technical Field

[0001] This utility model relates to the field of sheet traction technology, specifically a continuous traction device for glass fiber pultruded sheets. Background Technology

[0002] In the fiberglass pultrusion production process, the coordinated operation of the hot mold and traction equipment controls the molding quality; otherwise, mold blockage and incomplete product curing may occur. Therefore, the setting of the traction device is particularly important for the fiberglass pultrusion process.

[0003] However, traditional gantry pultrusion equipment has many serious problems, such as the difficulty in synchronizing the speeds of two gantry units when they operate alternately, which can easily cause jerking and damage to the product when it exits the hot mold due to speed differences. Therefore, a continuous traction device for fiberglass pultruded sheets is provided (see patent number: 202122370956.9), including a chassis, with through holes for the sheet to pass through on the lower part of both side walls of the chassis; a first annular belt is provided at the bottom of the chassis, with first support wheels at both ends of the first annular belt, and several rollers are provided on the upper and lower sides of the first annular belt; and a... The device includes a second annular belt with second support wheels at both ends. A horizontal plate is positioned between the upper and lower sides of the second annular belt, and several clamping cylinders are located on the lower side of the horizontal plate. Each clamping cylinder is connected to a roller frame, and several clamping rollers are installed at the lower end of the roller frame. The machine housing contains two fixed guide rollers and one movable guide roller. A trough is located on the upper part of the machine housing, and a slider that slides vertically along the trough is located inside the trough. A spring connects the slider to the upper side wall of the trough, and the slider is connected to the movable guide roller. This invention can stably clamp and continuously traction the sheet material, preventing deformation of the sheet material, and is suitable for traction of fiberglass pultruded sheets of different thicknesses.

[0004] However, most of the existing glass fiber pultruded sheet continuous traction devices on the market can only clamp and traction sheets of specific shapes. When encountering irregularly shaped sheets, they cannot achieve a firm clamping operation, causing the sheet to slip off from the traction device and affecting the sheet forming. Utility Model Content

[0005] The purpose of this invention is to address the problem that most current continuous traction devices for glass fiber pultruded sheets can only clamp and traction sheets of specific shapes. When encountering irregularly shaped sheets, they cannot achieve a firm clamping operation, leading to the sheet slipping off the traction device and affecting the sheet forming. This invention provides a continuous traction device for glass fiber pultruded sheets.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a continuous traction device for glass fiber pultruded sheet, including a worktable, a clamping assembly on the top of the worktable, a snap-fit ​​assembly on one side of the clamping assembly, a support frame on the outside of the clamping assembly, and support pads at the four corners of the bottom of the worktable.

[0007] The clamping assembly includes a housing, with movable frames at the top and bottom inside the housing. A clamping frame is provided at the end of each movable frame away from the housing. Multiple clamping rods are provided at the end of each clamping frame away from the movable frames. A connecting frame is provided on one side of each movable frame. A gear is provided on one side of the top of one of the connecting frames.

[0008] The snap-fit ​​assembly includes a snap-fit ​​frame, with a first micro elastic element at the top and bottom inside the snap-fit ​​frame, a locking block on one side of each of the two sets of first micro elastic elements, a locking groove on the outside of each of the two sets of locking blocks, a second micro elastic element at the top and bottom of one side of the snap-fit ​​frame, and a push rod on the side of the snap-fit ​​frame away from the second micro elastic element.

[0009] As a further improvement of this utility model: one side of the top of one set of movable frames is provided with a spring, and the movable frame is elastically connected to the outer shell through the spring.

[0010] As a further improvement of this utility model, multiple sets of clamping wheels are provided on the outside of each set of clamping rods.

[0011] As a further improvement of this utility model: multiple sets of locking teeth are provided on one side of the outer side of both sets of connecting frames, and both sets of connecting frames are connected to gears through the locking teeth.

[0012] As a further improvement of this utility model: one set of movable frames is clamped to the card-connecting frame through a card block and a card slot.

[0013] As a further improvement of this utility model: the push rod is provided with a pulley inside, and a limiting block is provided on the side of the push rod away from the snap-fit ​​frame. The snap-fit ​​frame is movably connected to the support frame through the push rod, the pulley and the limiting block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the clamping assembly, when the moving frame moves to the leftmost position, the connecting frame at the top descends through the limiting block, which in turn drives the top connecting frame to descend. Furthermore, through gears, the two sets of connecting frames move inward, causing the clamping frame to move inward, which in turn drives multiple sets of clamping rods to move, thereby clamping and fixing the plate. This facilitates the clamping and fixing of plates of different shapes to meet the fixing requirements of different plates. In addition, the elastic element reduces the cracking of the plate caused by large clamping force.

[0016] 2. This utility model, through its snap-fit ​​assembly, allows a set of connecting frames to be raised to the top, with the snap-fit ​​block moving into the slot to lock the position of the connecting frames. This reduces the movement of the clamping frames during the transport of the sheet metal, preventing insecure clamping. The sheet metal is then transported to the right. After moving to the far right, the snap-fit ​​frame moves inward through the push of the limit block, and the snap-fit ​​block disengages from the slot. Through springs and gears, the two sets of clamping frames open. The opening and closing operation can be achieved through mechanical components, thereby reducing the use of electronic components, preventing damage to electronic components and difficulties in maintenance that could extend the construction period, and reducing the use and maintenance costs of the device.

In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0024] like Figures 1 to 4 As shown, this utility model provides a continuous traction device for glass fiber pultruded sheets, including a worktable 1, a clamping assembly 2 on the top of the worktable 1, a snap-fit ​​assembly 3 on one side of the clamping assembly 2, a support frame 4 on the outside of the clamping assembly 2, and support pads 5 at the four corners of the bottom of the worktable 1.

[0025] The clamping assembly 2 includes a housing 201. The top and bottom of the housing 201 are provided with movable frames 202. The ends of the two movable frames 202 away from the housing 201 are provided with clamping frames 203. The ends of the two clamping frames 203 away from the movable frames 202 are provided with multiple clamping rods 204. The side of the two movable frames 202 is provided with a connecting frame 206. One of the connecting frames 206 has a gear 207 on one side of its top.

[0026] The snap-fit ​​assembly 3 includes a snap-fit ​​bracket 301. The top and bottom of the snap-fit ​​bracket 301 are provided with first micro elastic elements 302. Each side of the two sets of first micro elastic elements 302 is provided with a snap block 303. The outside of the two sets of snap blocks 303 is provided with a snap groove 304. The top and bottom of the outside side of the snap-fit ​​bracket 301 are provided with second micro elastic elements. The outside side of the snap-fit ​​bracket 301 away from the second micro elastic elements 305 is provided with a push rod 306.

[0027] like Figures 1 to 4 As shown, a spring 208 is provided on one side of the top of one set of movable frames 202, and the movable frame 202 is elastically connected to the outer shell 201 through the spring 208.

[0028] In this embodiment, spring 208 is a mechanical part that works by utilizing elasticity. A part made of elastic material deforms under the action of external force and returns to its original shape after the external force is removed. It is also called a "spring" and is generally made of spring steel. There are many types of springs 208. According to their shape, they mainly include helical springs, spiral springs, leaf springs, and irregular springs. This embodiment mainly uses helical springs.

[0029] like Figures 1 to 4 As shown, multiple clamping rods 204 are equipped with multiple clamping wheels on their exterior.

[0030] In this embodiment, the multiple sets of clamping wheels designed can generate friction with the plate due to the rotation of the clamping rod 204 during clamping operations, thereby causing wear and cracking of the plate and affecting its later use.

[0031] like Figures 1 to 4 As shown, each of the two sets of connecting frames 206 has multiple sets of locking teeth on one side of its exterior, and both sets of connecting frames 206 are connected to the gear 207 by the locking teeth.

[0032] In this embodiment, the meshing connection provides a strong connection, preventing loosening and detachment between components, ensuring the stable operation of the mechanical system, and making maintenance and replacement of components more convenient and faster. The meshing connection can adapt to different materials and shapes, and by designing appropriate tooth shapes and sizes, a reliable connection between different components can be achieved.

[0033] like Figures 1 to 4 As shown, one set of movable frames 202 is clamped to the card holder 301 through the card block 303 and the card slot 304.

[0034] In this embodiment, the card block and the card slot are two common mechanical structures. They play their respective roles in different application scenarios and play an important role in modern industrial design. They achieve convenient assembly and fixing functions through simple mechanical structures.

[0035] like Figures 1 to 4 As shown, the push rod 306 has a pulley inside, and a limiting block 307 is provided on the side of the push rod 306 away from the snap-fit ​​bracket 301. The snap-fit ​​bracket 301 is movably connected to the support frame 4 through the push rod 306, the pulley and the limiting block 307.

[0036] In this embodiment, the above structure enables the opening and closing operation of rotation through mechanical components, thereby reducing the use of electronic devices and preventing damage to electronic components and difficulties in maintenance that could extend the construction period.

[0037] The working principle of this utility model is as follows: When in use, the movable frame 202 moves to the left. When the movable frame 202 moves to the leftmost position, the connecting frame 206 at the top descends through the limiting block 307, which drives the connecting frame 206 at the top to descend. Through the meshing connection between the gear 207 and the connecting frame 206, another set of connecting frames 206 moves upward, which in turn drives the clamping frames 203 connected to each other to move, which in turn drives multiple sets of clamping rods 204 to move, thereby clamping and fixing the plate. At the same time, the elastic element 205 makes the clamping rods 204 stick tightly to the plate.

[0038] After a set of connecting frames 206 rises to the top, the locking block 303 moves into the slot 304 to lock the position of the connecting frame 206. The outer shell 201 moves to the right to transport the sheet metal. After moving to the rightmost side, the push rod 306 moves inward through the push of the limit block 307, which in turn drives the clamping frame 301 to move inward. At the same time, the second micro elastic element 305 is compressed, and the locking block 303 is disengaged from the slot 304. The connecting frame 206 moves downward through the elastic force of the spring 208, and through the meshing connection with the gear 207, the other set of connecting frames 206 rises, thereby opening the two sets of clamping frames 203. Then, the movement to the left is repeated to perform the cyclic sheet metal transport operation.

[0039] The clamping component 2 of this device can easily clamp and fix plates of different shapes to meet the fixing requirements of different plates. The elastic element 205 reduces the cracking of the plates caused by large clamping forces, ensuring the production of the plates. The snap-fit ​​component 3 can realize the rotation opening and closing operation through mechanical components, thereby reducing the use of electronic components, preventing damage to electronic components and the extension of the construction period due to difficulty in maintenance, and reducing the use and maintenance costs of the device.

[0040] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
