Description

Technical Field

[0001] The utility model relates to the technical field of molding machines, in particular to a molding machine with a tensioning device. Background Art

[0002] As an indispensable and important equipment in modern industrial production, the compression molding machine is widely used in the production process of artificial boards, plastic products and other industries. It usually includes a pressure roller group and a compaction belt. The pressure roller group presses the material by applying uniform pressure to ensure the flatness and density of the product. The compaction belt is directly in contact with the outer roller surface of the pressure roller group, effectively isolating the direct contact between the pressure roller group and the material, protecting the outer roller surface of the pressure roller group from material wear and contamination, and extending its service life.

[0003] Through the isolation effect of the compaction belt, the material will not directly contact the roller surface during the pressing process, thus avoiding possible damage such as scratches and dents on the roller surface and reducing the cost of repairing and replacing the roller surface.

[0004] However, the compaction belt gradually undergoes elastic deformation under long-term force, resulting in a decrease in its tightness. Once the compaction belt is loose, it cannot maintain its original flatness and tightness. The loose compaction belt is prone to leaving defects such as indentations and wrinkles on the surface of the board during the pressing process, which seriously affects the molding quality of the artificial board products.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Combine the following Figures 1 to 8 , describing a forming machine with a tensioning device according to an embodiment of the utility model.

[0039] A forming machine with a tensioning device, comprising a frame 1, an outer cover 2, a pressing device 3, a feeding device 4 and a tensioning device 5, wherein the outer cover 2 is mounted on the top of the frame 1, the inner wall of the outer cover 2 and the frame 1 form a pressing space, the feeding device 4 is mounted on the frame 1, and the feeding device 4 is used to transport materials into the pressing space;

[0040] The material pressing device 3 includes a moving assembly 31, a pressing plate 32, a pressure roller group 33 and a compacting belt 34. The pressure roller group 33 is installed at the bottom of the pressing plate 32. The compacting belt 34 is located at the bottom of the pressure roller group 33. The compacting belt 34 abuts against the outer roller surface of the pressure roller group 33. The pressure roller group 33 is used for rolling and pressing materials. The top of the pressing plate 32 is provided with a moving assembly 31, and the moving assembly 31 is used to move the pressing plate 32 forward and backward.

[0041] The tensioning device 5 is installed at the front and rear ends of the pressing plate 32 , and the tensioning device 5 is used to tighten the compacting belt 34 .

[0042] In the present embodiment of a forming machine with a tensioning device, the feeding device 4 can convey the material into the pressing space so that the material is located below the pressing device 3. At this time, one side of the compacting belt 34 abuts against the pressure roller group 33, and the other side abuts against the material.

[0043] The compacting belt 34 can protect the roller surface of the pressure roller set 33 from being worn and contaminated by the material, thereby extending its service life. Through the isolation effect of the compacting belt 34, the material will not directly contact the roller surface of the pressure roller set 33 during the pressing process, thereby avoiding possible scratches, dents and other damages on the roller surface of the pressure roller set 33.

[0044] When the moving assembly 31 moves the pressing plate 32 forward and backward, the pressing plate 32 drives the pressure roller group 33 to roll the material in the forward and backward directions, thereby pressing out an artificial board with uniform force and dense structure.

[0045] It is worth mentioning that the tensioning device 5 can adjust the tension of the compacting belt 34 to ensure that the compacting belt 34 is always in a straight state, effectively avoiding the compacting belt 34 from leaving defects such as indentations and wrinkles on the surface of the formed artificial board during the pressing process, and solving the problem that the traditional compacting belt 34 becomes loose, which seriously affects the forming quality of the artificial board product.

[0046] The tensioning device 5 includes a first tensioning mounting plate 51, a second tensioning mounting plate 52, a tensioning power member 53, a first tensioning block 54 and a second tensioning block 55;

[0047] The first tensioning mounting plate 51 is slidably mounted on the front end of the pressing plate 32, the tensioning power member 53 is mounted on the bottom of the first tensioning mounting plate 51, and the output end of the tensioning power member 53 is mounted with the first tensioning block 54, and the first tensioning block 54 is fixedly connected to one end of the compacting belt 34;

[0048] The second tensioning mounting plate 52 is installed at the rear end of the pressing plate 32 , and the second tensioning block 55 is fixedly connected to the other end of the compacting belt 34 .

[0049] The tensioning power member 53 is a pneumatic cylinder or an oil cylinder. When the tensioning power member 53 is activated, the output end of the tensioning power member 53 contracts inward, thereby adjusting the length of the compacting belt 34, which can effectively ensure that the compacting belt 34 is in a straight state for a long time, and avoid the compacting belt 34 from abutting against the surface of the material downward when the compacting belt is in a relaxed state, resulting in unnecessary texture marks on the surface of the artificial board product.

[0050] The first tensioning mounting plate 51 and the second tensioning mounting plate 52 are both L-shaped plates. A first slider 57 is provided at the bottom of the horizontal end of the first tensioning mounting plate 51. A first slide rail 56 is provided at the top of the pressing plate 32. The first slider 57 and the first slide rail 56 are arranged opposite to each other. The first slide rail 56 and the first slider 57 are slidably connected. The tensioning power member 53 is installed at the vertical end of the first tensioning mounting plate 51.

[0051] A second slider 59 is provided at the bottom of the horizontal end of the second tensioning mounting plate 52, and a second slide rail 58 is provided on the top of the pressure plate 32. The second slider 59 and the second slide rail 58 are arranged opposite to each other, and the second slide rail 58 and the second slider 59 are slidably connected. The second tensioning block 55 is installed at the vertical end of the second tensioning mounting plate 52.

[0052] It is worth noting that in the present embodiment, the first tensioning mounting plate 51 and the second tensioning mounting plate 52 are both L-shaped plates, and the pressure plate 32 is slidably connected to the horizontal ends of the first tensioning mounting plate 51 and the second tensioning mounting plate 52, respectively, so that the distance from the vertical end of the first tensioning mounting plate 51 to the vertical end of the second tensioning mounting plate 52 is the movable distance of the pressure plate 32.

[0053] The cooperation between the first slide rail 56, the first slider 57, the second slide rail 58 and the second slider 59 can limit the moving direction of the pressing plate 32, ensuring that the pressing plate 32 can drive the pressure roller group 33 to move along the front-rear direction and roll and press the material.

[0054] Since the first tensioning block 54 is installed on the first tensioning mounting plate 51 and the second tensioning block 55 is installed on the second tensioning mounting plate 52, the compaction belt 34 is in a relatively static and straight state and will not move with the rotation of the pressure roller group 33, further reducing the occurrence of unnecessary texture marks on the surface of the artificial board product.

[0055] A vertical second lifting member 21 is provided at the top of the outer cover 2, and two second lifting members 21 are installed on the outer cover 2. The output end of one second lifting member 21 movably extends into the outer cover 2 and is connected to the top of the first tensioning mounting plate 51, and the output end of the other second lifting member 21 movably extends into the outer cover 2 and is connected to the top of the second tensioning mounting plate 52.

[0056] Among them, the second lifting member 21 is an oil cylinder or a vacuum-powered cylinder. It is worth noting that the two second lifting members 21 simultaneously retract the output end upward, so that the first tensioning mounting plate 51, the second tensioning mounting plate 52 and the pressing plate 32 move upward together, thereby increasing the distance between the pressure roller group 33 and the feeding device 4, so that thicker materials can be pressed. The two second lifting members 21 simultaneously extend the output end downward, so that the first tensioning mounting plate 51, the second tensioning mounting plate 52 and the pressing plate 32 move downward together, so that the distance between the pressure roller group 33 and the feeding device 4 becomes smaller, thereby pressing thinner materials. Therefore, the molding machine of this scheme can adjust the height of the pressure roller group 33, so that materials of different thicknesses can be pressed by the pressing device 3 into densely structured artificial boards.

[0057] The feeding device 4 includes a feeding power member, a first feeding roller 41, a second feeding roller 42 and a conveyor belt 43;

[0058] The feeding power member is fixedly connected to the first feeding roller 41 , and the conveyor belt 43 is sleeved on the first feeding roller 41 and the second feeding roller 42 .

[0059] It is worth noting that the feed power member is a motor. When the feed power member is started, the feed power member can drive the first feed roller 41 to rotate, and the rotation of the first feed roller 41 can drive the second feed roller 42 and the conveyor belt 43 to move, so that the conveyor belt 43 can transport the material to the pressing space for pressing. Moreover, after the material is pressed and formed, the material can also be transported to the next station outside the frame 1.

[0060] A vertical first lifting member 11 is disposed on the side wall of the outer cover 2 . The output end of the first lifting member 11 is connected to the frame 1 . The first lifting member 11 is used to drive the outer cover 2 to move vertically.

[0061] The first lifting member 11 is an oil cylinder or a vacuum powered cylinder. When the first lifting member 11 is started, the first lifting member 11 can drive the outer cover 2 to move up and down, ensuring that the material can be transported into the pressing space by the feeding device 4, so that the pressing device 3 can press the material, thereby obtaining a dense artificial board.

[0062] The moving component 31 includes a first moving power component 3101, a first transmission wheel 3102 and a first connecting rod 3103. The first moving power component 3101 is installed on the inner wall of the outer cover 2, the output end of the first moving power component 3101 is connected to the first transmission wheel 3102, the top of the first connecting rod 3103 is connected to the first transmission wheel 3102, and the bottom of the first connecting rod 3103 is hinged to the top of the pressure plate 32.

[0063] Reference Figure 1 It is worth noting that the output end of the first mobile power member 3101 is fixedly connected to the first transmission wheel 3102, and the first transmission wheel 3102 and the first mobile power member 3101 are eccentrically arranged, and the top of the first connecting rod 3103 is rotatably connected to the outer circumferential surface of the first transmission wheel 3102. Therefore, when the first mobile power member 3101 is started, the first mobile power member 3101 drives the first transmission wheel 3102 to rotate. Since the first transmission wheel 3102 and the first mobile power member 3101 are eccentrically arranged, the first transmission wheel 3102 makes a circular motion around the output end of the first mobile power member 3101, thereby driving the first connecting rod 3103 to swing, and then driving the movement of the pressure plate 32.

[0064] Since the first slide rail 56 and the second slide rail 58 are provided on the pressing plate 32, the first slide rail 56 and the second slide rail 58 can limit the moving direction of the pressing plate 32, ensuring that the pressing plate 32 and the pressure roller group 33 move along the front-to-back direction, so that the pressure roller group 33 can roll and press the material.

[0065] Example 2

[0066] The difference between this embodiment and embodiment 1 is that: Figure 4 , the output end of the first moving power member 3101 is coaxially arranged with the first transmission wheel 3102, the first transmission wheel 3102 is hinged with the top of the first connecting rod 3103, and the top of the first connecting rod 3103 is eccentrically arranged with the first transmission wheel 3102. At this time, the first connecting rod 3103 can drive the pressing plate 32 to move above the feeding device 4. Since the pressing plate 32 is provided with the first slide rail 56 and the second slide rail 58, at this time, the first slide rail 56 and the second slide rail 58 can limit the moving direction of the pressing plate 32, ensuring that the pressing plate 32 and the pressure roller group 33 move along the front-back direction, so that the pressure roller group 33 can roll and press the material.

[0067] Example 3
