Description

Technical Field

[0001] The utility model relates to a vertical two-roller forming machine and forming equipment. Background Art

[0002] Currently, after being extruded from the extruder, the product needs to enter a three-roll forming machine or a two-roll forming machine for forming. The advantage of a two-roll forming machine over a three-roll forming machine is that the product does not need to bend when passing through the two-roll forming machine, thereby avoiding the problem of tearing and damage of the product due to bending.

[0003] A two-roll forming machine typically consists of upper and lower rollers, with a passage between them for the product to pass through. At the start of production, the upper and lower rollers must be opened, and the extruded product must be passed between them before being closed. Opening the upper and lower rollers before threading the product creates a wider feed channel, facilitating smooth insertion of the product's front end between the upper and lower rollers. This significantly reduces the difficulty of threading thicker or unusually shaped products.

[0004] In the prior art, the opening and closing of the upper and lower rollers is typically driven by a screw lift. Manually turning the screw lift drives the upper roller, thereby opening and closing the upper and lower rollers. However, the screw lift's speed is slow, which in turn drives the upper roller's movement. This results in a slower opening and closing of the upper and lower rollers, wasting time and affecting threading speed and efficiency. Furthermore, using a screw lift to drive the upper roller's movement to open and close the rollers makes it impossible to adjust the pressure between the two rollers. Utility Model Content

The screw elevator can conveniently and accurately adjust the height of the upper roller, thereby precisely adjusting the gap between the upper and lower rollers, that is, the size of the material passage, to produce products of different thicknesses.

[0042] When starting production, the sliding part can slide up and down by the extension and retraction of the hydraulic cylinder, and then the upper roller moves up and down to realize the opening and closing of the upper roller and the lower roller. On the one hand, compared with the screw lifter, the movement speed of the upper roller is greatly improved by driving the upper roller to move through the hydraulic cylinder, thereby improving the opening and closing speed of the upper roller and the lower roller, and realizing rapid opening and closing to save the time of threading and improve the speed and efficiency of threading. On the other hand, by adjusting the output force of the hydraulic cylinder, the pressing force of the upper roller and the lower roller on the product can be adjusted. The greater the output force of the hydraulic cylinder, the greater the pressing force of the upper roller and the lower roller on the product, and then the pressing force between the upper roller and the lower roller can be adjusted to an appropriate size as needed. The purpose of such design is that when a sudden situation occurs to cause the thickness of the product entering between the upper roller and the lower roller to suddenly increase, the product will exert an upward thrust on the upper roller. When the thrust is large enough, it can offset the output force of the hydraulic cylinder and then lift the upper roller upward, thereby avoiding that the device is damaged by the sudden thickening of the product in the event of an emergency.

[0047] In order to make the content of the utility model more easily and clearly understood, the utility model will be further described in detail below according to specific embodiments and in conjunction with the drawings.

[0048] Embodiment one

[0050] The sliding part is slidably connected to the rack 1 in the up-down direction;

[0051] The upper roller 2 is rotatably connected to the sliding part;

[0052] The lower roller 3 is rotatably connected to the rack 1 and located below the upper roller 2, and a threading channel for the product to pass through is arranged between the upper roller 2 and the lower roller 3;

[0053] The screw rod lift is connected to the frame 1, one end of the hydraulic cylinder is connected to the corresponding screw rod lift, the other end of the hydraulic cylinder is connected to the sliding part, the hydraulic cylinder is used to drive the sliding part to slide up and down, and in turn drive the upper roller 2 to move up and down to realize the opening and closing of the upper roller 2 and the lower roller 3, and the screw rod lift is used to drive the hydraulic cylinder, the sliding part and the upper roller 2 to move up and down to adjust the gap size between the upper roller 2 and the lower roller 3.

[0054] Specifically, the product extruded from the extruder needs to pass through the threading channel so as to be formed by the upper roller 2 and the lower roller 3. When products of different thicknesses need to be produced, the hydraulic cylinder can be kept in an elongated state, the screw rod lift is manually rotated, and in turn the hydraulic cylinder, the sliding part and the upper roller 2 are driven by the screw rod lift to move up and down to adjust the gap size between the upper roller 2 and the lower roller 3, so as to be able to form products of different thicknesses. The height of the upper roller 2 can be conveniently and accurately adjusted by the screw rod lift, and in turn the gap size between the upper roller 2 and the lower roller 3, i.e. the size of the threading channel, can be accurately adjusted, so as to produce products of different thicknesses.

[0055] When the production of threading is just started, the sliding part can be driven by the extension and retraction of the hydraulic cylinder to slide up and down, and in turn the upper roller 2 is driven to move up and down to realize the opening and closing of the upper roller 2 and the lower roller 3. On the one hand, compared with the screw rod lift, the movement speed of the upper roller 2 is greatly improved by the hydraulic cylinder, and in turn the opening and closing speed of the upper roller 2 and the lower roller 3 is improved, so as to realize rapid opening and closing to save the threading time and improve the threading speed and efficiency. On the other hand, the pressing force of the upper roller 2 and the lower roller 3 on the product can be adjusted by adjusting the output force of the hydraulic cylinder, the greater the output force of the hydraulic cylinder is, the greater the pressing force of the upper roller 2 and the lower roller 3 on the product is, and in turn the pressing force between the upper roller 2 and the lower roller 3 can be adjusted to a suitable size as needed. The purpose of such design is that when an emergency situation occurs and the thickness of the product entering between the upper roller 2 and the lower roller 3 suddenly increases, the product will exert an upward pushing force on the upper roller 2, and when the pushing force is large enough, the output force of the hydraulic cylinder can be offset and in turn the upper roller 2 is lifted up, so as to avoid that the equipment is damaged by the sudden thickening of the product in the emergency situation. However, the pressing force between the upper roller 2 and the lower roller 3 cannot be adjusted by the screw rod lift used in the prior art, and the position of the upper roller 2 cannot be moved after the screw rod lift drives the upper roller 2 to move to close the lower roller 3, and no matter how large the pushing force exerted by the product on the upper roller 2 is, the upper roller 2 cannot be lifted up, and in turn the equipment will be damaged by the sudden thickening of the product in the emergency situation.

Specifically, when different thickness products need to be produced, the height of the first sliding seat 8 can be fine-tuned by driving the first hydraulic cylinder 4 and the first sliding seat 8 to move up and down through the first screw rod elevator 6, and the height of the second sliding seat 9 can be fine-tuned by driving the second hydraulic cylinder 5 and the second sliding seat 9 to move up and down through the second screw rod elevator 7, thereby accurately adjusting the height of the upper roller 2 to conveniently and accurately adjust the gap size between the upper roller 2 and the lower roller 3, and thereby forming products of different thicknesses. Further specifically, the first hydraulic cylinder 4 can drive the first sliding seat 8 to move up and down by extending and retracting, and the second hydraulic cylinder 5 can drive the second sliding seat 9 to move up and down by extending and retracting, thereby driving the upper roller 2 to move up and down to quickly open and close the upper roller 2 and the lower roller 3, improving the moving speed of the upper roller 2, saving the time of threading, and improving the speed and efficiency of threading.

[0074] As shown in Figure 3 , 4 A forming device, comprising the vertical two-roller forming machine as described in embodiment one and a wave forming device 100 arranged behind the vertical two-roller forming machine;

[0075] The wave forming device 100 comprises a mounting frame 17 and at least two forming mechanisms arranged in sequence from front to back;

[0076] The forming mechanism comprises an upper wave forming roller 18, a lower wave forming roller 19, a left connecting seat, a right connecting seat, a left air cylinder 20 and a right air cylinder 21;

[0077] The left connecting seat and the right connecting seat are respectively connected to the mounting frame 17 in the up-down direction;

[0078] One end of the upper wave forming roller 18 is rotatably connected to the left connecting seat, and the other end of the upper wave forming roller 18 is rotatably connected to the right connecting seat;

[0079] The lower wave forming roller 19 is rotatably connected to the mounting frame 17 and located below the upper wave forming roller 18, and a forming channel for the product to pass through is arranged between the upper wave forming roller 18 and the lower wave forming roller 19;

[0080] The left air cylinder 20 is connected to the mounting frame 17 and connected to the left connecting seat and used to drive the left connecting seat to move up and down, and the right air cylinder 21 is connected to the mounting frame 17 and connected to the right connecting seat and used to drive the right connecting seat to move up and down, thereby being able to drive the upper wave forming roller 18 to move up and down, so that the upper wave forming roller 18 and the lower wave forming roller 19 are opened and closed; wherein the specific structure of the upper wave forming roller 18 and the lower wave forming roller 19 is well known to those skilled in the art and is not described in detail in this embodiment.

[0081] AsFigure 3 、 4 As shown in FIG. 1, the wave forming device 100 can further comprise a power mechanism 22 connected with the lower wave forming roller 19 and used for driving the lower wave forming roller 19 to rotate; in the embodiment, the forming mechanism is provided with three power mechanisms, and the lower wave forming roller 19 is also provided with three power mechanisms, one of the power mechanisms 22 is connected with one of the lower wave forming rollers 19, and the adjacent lower wave forming rollers 19 can be connected through gear mechanisms for same direction transmission, and the power mechanism 22 can comprise a motor and a speed reducer.

[0082] As shown in FIG. 1, Figure 3 、 4 The wave forming device 100 can further comprise an oven 23 connected with the mounting frame 17 and located in front of the forming mechanism.

[0083] The oven 23 is located behind the upper roller 2 and the lower roller 3,

[0084] The oven 23 is provided with a heating channel so that the product sequentially passes through the feeding channel, the heating channel and the forming channel.

[0085] As shown in FIG. 1, Figure 3 、 4As shown, the wave forming device 100 can further comprise a cooling bracket 24 connected to the mounting frame 17, which is located behind the forming mechanism and used to receive the product passing through the forming channel. Specifically, the product extruded by the extruder enters the feeding channel between the upper roller 2 and the lower roller 3 to be formed into a flat plate, and then the product extends into the forming channel after passing through the heating channel in the oven 23, which is used to heat and shape the product to prevent it from deforming and shrinking due to rapid cooling. The setting of the oven 23 can reduce the rate of temperature drop of the product. In the forming channel, the upper wave forming roller 18 and the lower wave forming roller 19 form the flat product into a wave plate, and then the product moves to the cooling bracket 24 for cooling and shaping. When it is needed to produce a wave plate, the left cylinder 20 drives the left connecting seat to move downward to the position, the right cylinder 21 drives the right connecting seat to move downward to the position, and then drives the upper wave forming roller 18 to move downward to the position, so that the upper wave forming roller 18 and the lower wave forming roller 19 can form the flat product into a wave plate. When it is needed to produce a flat plate, the left cylinder 20 drives the left connecting seat to move upward to the position, the right cylinder 21 drives the right connecting seat to move upward to the position, and then drives the upper wave forming roller 18 to move upward to the position, so that the upper wave forming roller 18 and the lower wave forming roller 19 are opened, and then the flat product directly passes between the upper wave forming roller 18 and the lower wave forming roller 19 and extends to the cooling bracket 24 for cooling and shaping. The forming device of the embodiment can be widely applied to the production of wave plates and flat plates of various formulas, and can ensure the qualified rate and production speed of the product.

[0086] As described above, the product extruded from the extruder needs to pass through the feeding channel to be formed by the upper roller 2 and the lower roller 3. When it is needed to produce products with different thicknesses, the hydraulic cylinder can be kept in an elongated state, and the lead screw lifter is manually rotated, and then the hydraulic cylinder, the sliding part and the upper roller 2 are driven by the lead screw lifter to move up and down together, so as to adjust the gap size between the upper roller 2 and the lower roller 3, and then products with different thicknesses can be formed. The height of the upper roller 2 can be conveniently and accurately adjusted by the lead screw lifter, and then the gap size between the upper roller 2 and the lower roller 3, i.e. the size of the feeding channel, can be accurately adjusted, so as to produce products with different thicknesses.

[0087] When threading begins, the hydraulic cylinder can be extended and retracted to drive the sliding member up and down, thereby driving the upper roller 2 up and down to open and close the upper roller 2 and lower roller 3. Compared to a screw-type elevator, using a hydraulic cylinder to drive the upper roller 2 significantly increases its movement speed, thereby increasing the speed at which the upper roller 2 and lower roller 3 open and close. This allows for quicker opening and closing, saving threading time and improving threading speed and efficiency. Furthermore, by adjusting the hydraulic cylinder's output force, the pressure exerted by the upper and lower rollers 2 and 3 against the product can be adjusted. The greater the hydraulic cylinder's output force, the greater the pressure exerted by the upper and lower rollers 2 and 3, allowing the pressure between the upper and lower rollers 2 and 3 to be adjusted to the desired level. This design is designed to prevent the product from suddenly increasing in thickness between the upper and lower rollers 2 and 3 due to an unexpected condition. The product will exert an upward thrust on the upper roller 2. A sufficiently strong thrust can offset the hydraulic cylinder's output force, pushing the upper roller 2 upward, thus preventing damage to the equipment caused by a sudden increase in product thickness.

[0088] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
