Description

Technical Field

[0001] This utility model relates to the field of processing soft and hard co-extruded sheets, and in particular to a forming, slitting and pressing device for soft and hard co-extruded sheets. Background Technology

[0002] In today's industrial production and numerous application fields, rigid-soft co-extruded sheets are widely used in various industries such as construction, automobiles, electronics, and medical devices due to their unique comprehensive performance advantages, which combine the strength and rigidity of rigid materials with the flexibility and elasticity of soft materials. Before installation and use, rigid-soft co-extruded sheets require operations such as drilling, cutting, and corner cutting. In actual production, different application scenarios often have diverse requirements for the width of the rubber strips. Traditional cutting equipment uses a fixed blade holder structure, and once the cutter is installed, it is difficult to adjust it. This limits its ability to cut rigid-soft co-extruded sheets to fixed sizes, making it difficult to meet customers' customized needs for rigid-soft co-extruded sheets of different sizes and affecting the diversified production and processing of sheets. Utility Model Content

A control panel is provided at the front end of the processing table, and an adjustment mechanism is provided above the fixed frame. The adjustment mechanism includes a mounting roller installed between two sets of fixed frames. A number of slitting circular cutters are slidably sleeved on the surface of the mounting roller. A limit block is fixedly connected to the surface of the slitting circular cutter. A moving groove is opened on the side of the mounting roller near the limit block. A gear is rotatably connected inside the limit block. A toothed plate is fixedly connected to the side of the mounting roller near the gear, and the toothed plate meshes with the surface of the toothed plate. A worm gear is fixedly connected to one side of the gear surface, and a worm is meshed with the surface of the worm gear.

[0007] Preferably, when it is necessary to cut soft and hard co-extruded sheets of different widths, the worm gear is rotated to drive the worm wheel to rotate, and then the worm wheel drives the gear connected to it to roll on the surface of the toothed plate, causing the limiting block to slide inside the mounting roller, so that the slitting circular knife moves laterally on the surface of the mounting roller, thereby adjusting the installation position of the slitting circular knife and adjusting the spacing between the slitting circular knives, so as to realize the slitting processing of soft and hard co-extruded sheets of different widths. Moreover, the adjusted position can be locked by the worm wheel and worm gear, improving the flexibility of processing soft and hard co-extruded sheets.

[0008] Furthermore, one end of the worm gear passes through the surface of the limiting block and is fixedly connected to a rotating component located on one side of the limiting block, which facilitates the rotation of the worm gear.

[0009] Furthermore, rotating seats are symmetrically connected to both sides of the mounting roller. A sliding groove is provided inside the fixed frame on the side near the rotating seat. The rotating seat slides inside the fixed frame through this sliding groove to ensure the stability of the connection between the mounting roller and the fixed frame.

[0010] Furthermore, a lifting mechanism is provided on the surface of the fixed frame. The lifting mechanism includes a first cylinder fixedly installed on the side of the fixed frame. The output end of the first cylinder is connected to the rotating seat. A first bevel gear is fixedly connected to the side of the mounting roller near the first cylinder.

The second bevel gear is rotatably connected to the surface of the fixed plate, which can adjust the height of the mounting roller.

[0011] Furthermore, a drive motor is fixedly connected to the top of the fixed frame near the fixed plate, a spline sleeve is fixedly connected to the output end of the drive motor, a spline shaft is fixedly connected to the surface of the second bevel gear, and the spline shaft slides inside the spline sleeve, which can drive the mounting roller to rotate.

[0012] Furthermore, a feeding rack is fixedly connected to one side of the processing table surface, and a feeding motor is installed on the side of the feeding rack to facilitate the conveying of soft and hard co-extruded rubber strips.

[0013] Furthermore, a cutter is slidably connected to the side of the fixed frame away from the feed frame, and a second cylinder is fixedly connected to the side of the fixed frame near the cutter. The two ends of the cutter are connected to the output end of the second cylinder, which can cut soft and hard co-extruded rubber strips to obtain soft and hard co-extruded rubber strips of different lengths.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting an adjustment mechanism, rotating the worm gear can drive the worm wheel to rotate, and then the worm wheel will drive the gear connected to it to roll on the surface of the toothed plate, causing the limiting block to slide inside the mounting roller, so that the slitting circular knife can move laterally on the surface of the mounting roller, thereby adjusting the installation position of the slitting circular knife and adjusting the spacing between the slitting circular knives, realizing the slitting processing of soft and hard co-extruded sheets of different widths. By setting a lifting mechanism, the drive motor can drive the mounting roller to rotate synchronously during slitting, improving the slitting and cutting effect of soft and hard co-extruded sheets. The first cylinder can push the mounting roller to move vertically, making it convenient for the slitting circular knife to be adjusted according to the thickness of the soft and hard co-extruded sheet, improving the flexibility of the device.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1:

[0026] See Figure 1-7This utility model provides an embodiment: it includes a processing table 1 and a fixing frame 5 symmetrically fixed above the processing table 1. A control panel 2 is provided at the front end of the processing table 1. An adjustment mechanism 3 is provided above the fixing frame 5. The adjustment mechanism 3 includes a mounting roller 33 installed between two sets of fixing frames 5. A plurality of slitting circular cutters 32 are slidably sleeved on the surface of the mounting roller 33. Limiting blocks 34 are fixedly connected to the surface of the slitting circular cutters 32. A moving groove is opened in the side of the mounting roller 33 near the limiting block 34. A gear 38 is rotatably connected inside the limiting block 34. A toothed plate 35 is fixedly connected in the side of the mounting roller 33 near the gear 38, and the toothed plate 35 meshes with the surface of the toothed plate 35. A worm gear 36 is fixedly connected to one side of the surface of the gear 38. The surface of 6 is meshed with a worm gear 37; when in use, the device slits the soft and hard co-extruded sheets by using slitting circular cutters 32. When it is necessary to cut soft and hard co-extruded sheets of different widths, the worm gear 37 is rotated to drive the worm wheel 36 to rotate. Then the worm wheel 36 will drive the gear 38 connected to it to roll on the surface of the toothed plate 35, and drive the limiting block 34 to slide inside the mounting roller 33, so that the slitting circular cutter 32 can move laterally on the surface of the mounting roller 33. This allows the installation position of the slitting circular cutter 32 to be adjusted, and the spacing between the slitting circular cutters 32 can be adjusted to achieve slitting processing of soft and hard co-extruded sheets of different widths. The adjusted position can be locked by the worm wheel 36 and the worm gear 37, which improves the flexibility of processing soft and hard co-extruded sheets.

[0027] One end of the worm gear 37 passes through the surface of the limiting block 34 and is fixedly connected to the rotating component 39 located on one side of the limiting block 34. The rotating component 39 facilitates the rotation of the worm gear 37. The mounting roller 33 is symmetrically rotatably connected to the two sides of the rotating seat 31. A sliding groove is provided inside the fixed frame 5 on the side near the rotating seat 31. The rotating seat 31 slides inside the fixed frame 5 through this sliding groove. The mounting roller 33 is installed between the fixed frames 5 through the rotating seat 31 to ensure the stability of the rotation of the mounting roller 33.

[0028] Example 2:

[0029] Please see Figure 1-7In this embodiment, a lifting mechanism 4 is provided on the surface of the fixed frame 5. The lifting mechanism 4 includes a first cylinder 41 fixedly installed on the side of the fixed frame 5. The output end of the first cylinder 41 is connected to the rotating seat 31. A first bevel gear 42 is fixedly connected to the side of the mounting roller 33 near the first cylinder 41. A second bevel gear 43 is meshed with the surface of the first bevel gear 42. A fixed plate 44 is fixedly connected to the surface of the rotating seat 31 near the second bevel gear 43, and the second bevel gear 43 is rotatably connected to the surface of the fixed plate 44. A drive motor 47 is fixedly connected to the top of the fixed frame 5 near the fixed plate 44. A spline sleeve 46 is fixedly connected to the output end of the drive motor 47. The surface of the second bevel gear 43 is fixedly connected to the spline sleeve 46. A splined shaft 45 is fixedly connected and slides inside the splined sleeve 46. Before processing the soft and hard co-extruded rubber strips, the first cylinder 41 is started to push the rotating seat 31 upward, which drives the mounting roller 33 upward. This allows the slitting round knife 32 to slide out from between the fixed frames 5, making it convenient to inspect or adjust the position of the slitting round knife 32 on the mounting roller 33. At the same time, the height of the mounting roller 33 can be adjusted to facilitate the slitting of soft and hard co-extruded rubber strips of different thicknesses. Starting the drive motor 47 will drive the splined sleeve 46 and the splined shaft 45 to rotate, and then drive the mounting roller 33 to rotate through the second bevel gear 43 and the first bevel gear 42, which facilitates the slitting operation of the slitting round knife 32 on the soft and hard co-extruded rubber strips.

[0030] A feeding frame 6 is fixedly connected to one side of the surface of the processing table 1, and a feeding motor 8 is installed on the side of the feeding frame 6. A cutter 7 is slidably connected to the side of the surface of the fixed frame 5 away from the feeding frame 6. A second cylinder 9 is fixedly connected to the side of the fixed frame 5 near the cutter 7, and both ends of the cutter 7 are connected to the output ends of the second cylinder 9. The feeding motor 8 can drive the feeding roller on the feeding frame 6 to rotate, which facilitates the feeding frame 6 to transport the soft and hard co-extruded rubber strips. After the stripping is completed, the second cylinder 9 is started to drive the cutter 7 to move downward, which enables the cutter 7 to cut the soft and hard co-extruded rubber strips to obtain soft and hard co-extruded rubber strips of different lengths.

[0031] Through the above steps, when the device is in use, the feeding motor 8 drives the feeding roller on the feeding frame 6 to rotate, conveying the soft and hard co-extruded rubber strips. Then, by starting the drive motor 47, the spline sleeve 46 and spline shaft 45 are driven to rotate, which in turn drives the mounting roller 33 to rotate through the second bevel gear 43 and the first bevel gear 42, causing the slitting circular blade 32 to slit the soft and hard co-extruded rubber strips. After slitting, the second cylinder 9 is started to drive the cutter 7 downward, enabling the cutter 7 to cut the soft and hard co-extruded rubber strips to obtain soft and hard co-extruded rubber strips of different lengths. The extruded strips are cut to obtain soft and hard co-extruded strips of different lengths. When it is necessary to cut soft and hard co-extruded sheets of different widths, the worm gear 37 is rotated to drive the worm wheel 36 to rotate. Then, the worm wheel 36 drives the gear 38 connected to it to roll on the surface of the toothed plate 35, which drives the limiting block 34 to slide inside the mounting roller 33. This allows the slitting circular blade 32 to move laterally on the surface of the mounting roller 33, thereby adjusting the installation position of the slitting circular blade 32 and adjusting the spacing between the slitting circular blades 32. This enables the slitting of soft and hard co-extruded sheets of different widths. Furthermore, the worm wheel 36 and worm gear 37 can lock the adjusted position, improving the stability of the processing of soft and hard co-extruded sheets.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
