DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] The drawings are only used for illustrative purposes and should not be construed as limitations on this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, which can be said to be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The following is combined with Figure 1 and 2 The technical solution of the utility model is further illustrated by specific implementation methods.

[0027] The utility model proposes a pressing and forming device using rollers for pressing materials. Figure 1 As shown, the pressing and forming device using roller pressing comprises an outer cover 1, a base 2 and a pressing assembly 4, wherein the outer cover 1 is connected to the base 2 so as to be able to be lifted up and down, the pressing assembly 4 is installed in the outer cover 1, and the base 2 is provided with a mold placement space;

[0028] The pressing assembly 4 includes a second driving member 41, a pressing plate 42, a plurality of rollers 43, a compacting belt 5 and a compacting belt driving subassembly 52. ​​The second driving member 41 is used to drive the pressing plate 42 to move up and down; the plurality of rollers 43 are arranged below the pressing plate 42, and the compacting belt 5 is installed below the rollers 43 through the compacting belt driving subassembly 52, and one side of the compacting belt 5 is used to contact the roller surface of the roller 43, and the other side is the pressing surface. The compacting belt driving subassembly 52 is used to adjust the tension of the compacting belt 5 and drive the compacting belt 5 to move back and forth.

[0029] In this solution, the mold containing the material is sent to the mold placement space by an external conveying device. The outer cover 1 can be driven down by an external force and form a closed space with the base 2. After the closed space is evacuated, the second driving member 41 in the material pressing assembly 4 drives the pressing plate 42 to descend, and the pressing plate 42 drives the roller 43 to move downward. The roller surface of the roller 43 contacts one side of the compacting belt 5. Under the action of the compacting belt driving subassembly 52, the compacting belt 5 will be tightly attached to the lower surface of multiple rollers 43. When the compacting belt 5 contacts the mold, the tight compacting belt 5 will initially flatten the unevenly distributed material on the mold surface, so that the material is evenly distributed on the mold. The compacting belt driving subassembly 52 reciprocates to pull the compacting belt 5. The compacting belt 5 drives the multiple rollers 43 to rotate under the action of friction, further making the material on the mold surface more uniform. In the prior art, the rollers sometimes rotate and sometimes do not rotate during the pressing process. The provision of the compacting belt 5 can solve the problem of the rollers not rotating.

[0030] Furthermore, the present solution also includes the material moving component 3, which includes a first driving member 31 and a material table 32. The material table 32 is movably arranged above the base 2, and the material table 32 is used to place a mold filled with material. The driving end of the first driving member 31 is connected to the material table 32, and the first driving member 31 is used to drive the material table 32 to reciprocate in a single direction.

[0031] In order to obtain a better pressing effect, the first driving member 31 drives the material table 32 to make horizontal reciprocating motion in a certain direction relative to the base 2, and the mold on the material table 32 also follows the reciprocating motion. Combined with the driving pressing of multiple rolling rollers 43 and the second driving member 41, the rollers 43 fully press the material on the mold, thereby improving the pressing efficiency and ensuring the flatness of the pressing.

[0032] The compaction belt driving subassembly 52 includes two driving members, which are respectively arranged at two ends of the arrangement direction of the roller bars 43, and the fixed ends of the driving members are connected to the pressing plate 42;

[0033] The driving ends of the two driving members are arranged opposite to each other, and the two ends of the compacting belt 5 are respectively connected to the driving ends of the two driving members, and the driving ends of the two driving members respectively drive the ends of the compacting belt 5 to move.

[0034] In this solution, the compaction belt driving subassembly 52 is composed of two driving members, and the tension of the compaction belt 5 and the reciprocating movement of the compaction belt 5 can be adjusted under the action of the driving members at both ends. Specifically, the two ends of the compaction belt 5 are provided with a fixed part, and the fixed part is used to connect with the driving end of the driving member. The fixed part can be a hook structure or a through-hole structure. The driving end of the driving member is provided with a matching hook, so that the end of the compaction belt 5 can be mounted on the driving end. When it is necessary to increase the tension of the compaction belt 5, the driving ends of the two driving members are controlled to move away from each other, tighten the compaction belt 5 and adjust the tension of the compaction belt 5. When it is necessary to reciprocate the compaction belt 5, the driving ends of the two driving members are controlled to move synchronously in the same direction, thereby driving the compaction belt 5 to reciprocate, and the compaction belt 5 is always kept in a taut state during the movement of the compaction belt 5. The movement of the compaction belt 5 and the tension adjustment of the compaction belt 5 can be achieved through two driving members, and the structure is simple and easy to install.

[0035] A clamping member 51 is provided at the connection between the compaction belt 5 and the compaction belt driving subassembly 52 , and the clamping member 51 is used to clamp and reinforce the connection between the compaction belt 5 and the compaction belt driving subassembly 52 .

[0036] It is worth noting that the arrangement of the clamping member 51 can prevent the compacting belt 5 from being separated from the driving end of the driving member during the pressing process.

[0037] The pressing assembly 4 also includes a side plate 44 , one end of which is connected to the pressing plate 42 , and the other end of the side plate 44 is rotatably mounted with a rotating shaft 431 of the roller 43 , the axis of which is perpendicular to the moving direction of the material table 32 .

[0038] like Figure 2 As shown, one end of the side plate 44 is fixedly connected to the surface of the pressure plate 42, and the rotating shaft 431 of the roller 43 is installed at the other end of the side plate 44. The roller 43 can be controlled to operate by controlling the pressure plate 42. The rotating shaft 431 of the roller 43 is perpendicular to the moving direction of the material table 32, as shown in FIG. Figure 1 In the process, the material table 32 reciprocates along the left and right direction, and the roller 43 is arranged along the front and back direction. This arrangement can make the roller 43 roll the material more fully, avoid the situation where uneven force is applied to some areas during the pressing process, reduce unnecessary waste of force, and thus achieve a labor-saving effect.

[0039] The rollers 43 are arranged along the moving direction of the material table 32. Figure 1 As shown, the material table 32 moves to the left and right directions, and the mold on its surface also moves to the left and right directions under the action of friction. In this embodiment, the rollers 43 are also arranged in the left and right directions. This arrangement can make the roller row composed of multiple rollers 43 form the largest contact area with the mold, ensuring that the entire material surface can be subjected to uniform pressure, thereby improving the consistency and quality of the production process. Continuous and uniform pressing can reduce unnecessary repetitive work, help reduce energy consumption, and make the production process more efficient.

[0040] The top of the base 2 is provided with a receiving cavity 21 , the material platform 32 and the first driving member 31 are arranged in the receiving cavity 21 , and the top of the receiving cavity 21 is arranged flush with the top of the base 2 .

[0041] The material table 32 and the first driving member 31 are placed in the accommodating cavity 21, and the top of the accommodating cavity 21 is arranged flush with the top of the base 2, so that the mold can be more conveniently delivered to the top surface of the material table 32 through an external conveying device, and the space of the device can be saved, the structure can be made more compact, and additional protection can be provided for the first driving member 31. In this embodiment, two first driving members 31 are provided, which are respectively arranged at the left and right ends of the material table 32. Compared with one first driving member 31, the two first driving members 31 can reduce the shaking caused by inertia when the material table 32 moves, making its movement more stable.

[0042] A detachable support seat 22 is provided at the bottom of the accommodating chamber 21 , and the material table 32 is slidably disposed above the support seat 22 .

[0043] Due to the weight of the material platform 32 and the pressure applied by the pressing plate 42 during pressing, the friction between the material platform 32 and the base 2 will cause the base 2 to wear seriously over time. In order to reduce the negative effects caused by wear, a support seat 22 is provided above the base 2. The number of support seats 22 can be increased according to the length of the material platform 32. The support seat 22 is fixedly connected to the base 2, and the material platform 32 can be slidably mounted on the surface of the support seat 22. In this embodiment, when the pressing work is performed, the material platform 22 performs left and right reciprocating translational motion on the support seat 22. If the support seat 22 is worn and cannot maintain normal operation, the support seat 22 can be disassembled and replaced with a new one, which effectively reduces the wear of the base 2 caused by friction.

[0044] A plurality of the second driving members 41 are provided, and driving ends of the plurality of the second driving members 41 are respectively connected to the upper end surface of the pressing plate 42 .

[0045] It is worth noting that by providing a plurality of second driving members 41 , the pressure plate 42 can be driven to move up and down. The plurality of second driving members 41 can increase the overall thrust output and is suitable for more application scenarios.

[0046] The power sources of the first driving member 31 , the second driving member 41 and the compacting belt driving subassembly 52 are oil cylinders or vacuum power.

[0047] Cylinder and vacuum power systems and other power sources can usually provide high torque output and are suitable for occasions requiring high power output. Cylinder and vacuum power systems usually have simple mechanical structures and therefore have high reliability. They are usually not easily affected by the external environment. The hydraulic system or vacuum system can provide precise force and speed control and is suitable for the present pressing and forming device utilizing roller pressing.

[0048] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
