Description

Technical Field

[0001] The invention relates to the technical field of steel belt presses, and in particular to a steel belt press with an edge pressing mechanism. Background Art

[0002] Layered composite materials are materials composed of two or more layers of different materials. They are mainly made by combining two or more plates with different properties through a certain process.

[0003] In the process of processing layered plates, a steel belt press is often used to press and form the layered plates. The material is placed between the steel belts, and then the steel belt moves under the rotation of the belt roller. Finally, the multi-layer material between the two steel belts is squeezed through the circular movement of the steel belt, and then combined with heating or other processes, the material is formed under certain pressure and temperature conditions. The pressure and temperature can be accurately controlled through the above means, and the plate can be evenly extruded so that the plate reaches a uniform thickness. When producing layered composite plates, one of the important reasons affecting the processing quality is the problem of the surface flatness of the steel belt during operation, which is an important reason affecting the uniformity of steel belt processing.

[0004] The Chinese patent with application number "202111006557.2" and patent name "A static isostatic double-belt continuous press" discloses a limit box, and the number of limit boxes is two. Then starting the electric push rod can drive the two pressing components closer to each other, so that the plate can be pressurized so that the plate can be evenly pressurized, and the pressure of the plate can be adjusted according to the movement of the push plate. At the same time, it can reduce the pressing stress of the pressing component, which has good practicality.

[0005] However, when the applicant was actually laminating the layered panels, he found that after long-term use, due to reasons such as early debugging or surface scratches, the steel strip would have a certain amount of deviation during processing, and after long-term use, it would also be poorly maintained (impurities and other hard particles on the surface of the steel strip were not completely removed). Although a deviation correction device is provided in the prior art to correct the deviation, after long-term use, due to each deviation and correction, and reciprocating movement, the edge of the steel strip will still have unevenness such as warping and twisting, which will inevitably affect the processing accuracy of the material. Summary of the invention

[0006] The object of the present invention is to provide a steel belt press with a edge pressing mechanism to solve the above-mentioned deficiencies in the prior art.

[0023] One end of the extrusion inclined block is provided with an extrusion inclined surface, and the extrusion inclined surface is located in the groove where the elastic slider is located. When the elastic slider is pressed and moves upward, the extrusion inclined surface is squeezed to drive the locking rod to separate from the sliding block.

[0056] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0057] See also Figure 1-Figure 11 A steel belt press with a pressing mechanism, comprising a support 1 and two belt rollers 11 arranged on the support 1, the two belt rollers 11 are arranged vertically up and down, and also comprising two steel belts 12, which are respectively sleeved on the two steel belts 12, and a horizontal frame 3 is also arranged on one side of the support 1, and also comprising: a pressing assembly, which comprises a pressing roller 22 and a supporting pressing roller 2321, and there is a gap between the pressing roller 22 and the supporting pressing roller 2321, and the steel belt 12 passes through the gap;

[0058] A supporting member, the bottom of which is arranged on the horizontal frame 3;

[0059] A second connecting block 23 is arranged on the horizontal frame 3, and the supporting pressing roller 2321 is movably arranged on the second connecting block 23 through a deviation correction component;

[0060] A first connecting block 21 is fixedly disposed on the second connecting block 23, an elastic slider 25 is vertically slidably disposed in the first connecting block 21, and a pressing roller 22 is movably disposed on the first connecting block 21;

[0061] A passive locking member 4, which is disposed in the first connecting block 21;

[0062] The elastic slider 25 has a first state and a second state.

[0063] In the first state, the pressing roller 22 elastically contacts the belt surface of the steel belt 12;

[0064] In the second state, the pressing roller 22 is in rigid contact with the belt surface of the steel belt 12;

[0065] When the elastic sliding block 25 is pressed and lifted by the surface of the steel belt 12 , it is passively switched from the first state to the second state through the passive locking member 4 .

[0066] Specifically, the lifting of the elastic slider 25 described in the present invention is generally divided into the following types: the edge of the steel belt 12 warps upward or downward, and the warping position is not in the same horizontal plane as the flat position relative to the flat surface of the steel belt 12, and the pressing roller 22 is squeezed, which eventually causes the elastic slider 25 to lift up, and the edge of the steel belt 12 warps upward or downward. Fig.11 In the state shown by the dotted line, the upward or downward bending can lift the elastic slider 25 in elastic contact.

[0067] The present invention uses an elastic slider 25 that is movably arranged, and then sets the pressing roller 22 on the elastic slider 25. During normal use, the steel strip 12 can be limited and squeezed by the elastic contact of the pressing roller 22, and the elastic contact can greatly reduce the wear on the steel strip 12 when the steel strip 12 is offset and corrected. In addition, when the edge of the steel strip 12 is warped, the elastic slider 25 can be triggered by the passive locking member 4, so that the elastic block and the steel strip 12 are in rigid contact in the second state, that is, not only can the elastic edge pressing of the steel strip 12 be achieved in normal times, but also when warping occurs, the pressing roller 22 can cooperate with the supporting pressing roller 2321 to rigidly squeeze the steel strip 12, so that it can be used to flatten the steel strip 12, greatly improve the efficiency of flattening the steel strip 12, and improve the flatness of the steel strip 12 as a whole, thereby improving the flatness and uniformity of the layered plate product.

[0068] In an embodiment further provided by the present invention, a guide column 422 is fixedly provided on the top of the elastic slider 25, and one end of the guide column 422 passes through the first connection block 21, and a third elastic member 2121 is sleeved on the outside of the guide column 422, one end of the third elastic member 2121 abuts against the inner wall of the first connection block 21, and the other end is connected and abuts against the top of the elastic slider 25. Specifically, the present invention can make the elastic slider 25 have a downward elastic force through the guide column 422 and the third elastic member 2121, thereby making the pressing roller 22 have a downward elastic force.

[0069] In an embodiment further provided by the present invention, the passive locking member 4 includes a sliding block 41 which is laterally slidably disposed in the first connecting block 21, and a limit lock groove 251 is provided on the elastic sliding block 25, and one end of the sliding block 41 corresponds to the notch of the limit lock groove 251;

[0070] A fourth elastic member 412 is disposed at one end of the sliding block 41 , and one end of the fourth elastic member 412 abuts against the upper inner wall of the first connecting block 21 .

[0071] Furthermore, a locking rod 43 is slidably provided on the first connecting block 21 , and a locking groove 411 adapted to the locking rod 43 is provided on the sliding block 41 , and the locking rod 43 is inserted into the locking groove 411 to limit the sliding block 41 .

[0072] Furthermore, the passive locking member 4 further comprises an extrusion bevel block 42 slidably disposed on the first connecting block 21, and a guide column 422 is fixedly disposed on the extrusion bevel block 42, and the guide column 422 is inserted into an inclined groove 431 provided in the locking rod 43;

[0073] An extrusion slope 421 is provided at one end of the extrusion slope block 42 , and the extrusion slope 421 is located in the groove where the elastic slider 25 is located. When the elastic slider 25 is pressed and moves upward, the extrusion slope 421 is squeezed to drive the locking rod 43 to separate from the sliding block 41 .

[0074] Specifically, the cooperation between the extrusion bevel block 42 and the locking rod 43 provided in the present embodiment can realize that when the elastic slider 25 is pressed and moves upward, the extrusion bevel 421 is squeezed and the locking rod 43 is driven to disengage from the sliding block 41, so that the sliding block 41 can move toward the direction of the elastic slider 25 under the elastic force of the fourth elastic member 412, so that the sliding block 41 can be passively inserted into the limiting lock groove 251 and the sliding block 41 can be fixed, so that the elastic slider 25 can be fixed, and then the pressing roller 22 is in rigid contact with the surface of the steel belt 12, and the belt surface of the steel belt 12 is rigidly squeezed.

[0075] Specifically, Fig. 9 As shown, the thickness of the extrusion bevel block 42 and the inclination of the inclined surface are set according to actual needs, which determine how much the warping size of the steel strip 12 can drive the pressing roller 22 to be in rigid contact.

[0076] In an embodiment further provided by the present invention, a pressing block 211 is rotatably provided on the top of the elastic slider 25, and one end of the pressing block 211 passes through the first connecting block 21, and a second elastic member 2111 is sleeved on the outside of the pressing block 211, and its elastic force makes the pressing block 211 have a tendency to move downward.

[0077] In an embodiment further provided by the present invention, a cam 213 is provided at one end of the pressing block 211 , and the cam 213 is located in the limiting lock groove 251 , and when the cam 213 is rotated, it can squeeze the sliding block 41 out of the limiting lock groove 251 .

[0078] The present invention sets the pressing block 211 and the cam 213 to cooperate with each other, which can not only further improve the elastic force requirement of the elastic slider 25 in the vertical direction, but also improve the stability of the vertical movement. Through the integrated setting of the cam 213, when the pressing roller 22 is converted from rigid contact to elastic contact, it is only necessary to rotate the cam 213. The cam 213 squeezes the sliding block 41 out of the limiting lock groove 251, and the elastic slider 25 can be placed in the first state relatively simply.

[0079] Another embodiment provided by the present invention further includes a passive deviation correction mechanism, which is arranged between the first connecting block 21 and the second connecting block 23;

[0080] The supporting component is a telescopic rod 26, and the telescopic end of the telescopic rod 26 is rotatably arranged on the second connecting block 23. When the steel belt 12 deviates, the passive deviation correction mechanism is driven to drive the telescopic rod 26 to move and correct the deviation.

[0081] In an embodiment further provided by the present invention, the passive deviation correction mechanism includes a movable block 241 slidably arranged below the first connecting block 21, and a side contact roller 24 is rotatably arranged on the movable block 241, and when the steel belt 12 moves, the side contact roller 24 rotates.

[0082] In the embodiment further provided by the present invention, a second contact 242 is provided on one side of the movable block 241, and a first contact 231 adapted to the second contact 242 is provided on the second connecting block 23. Specifically, the first contact 231 and the second contact 242 are used to start the telescopic rod 26, and the first contact 231 and the second contact 242 are respectively electrically connected to the positive and negative poles of the switch for controlling the telescopic rod 26. When the first contact 231 and the second contact 242 are in contact, the telescopic rod 26 starts to move and moves to a specified position, and then the offset steel strip 12 can be tilted upward as a whole, and then the steel strip 12 is gradually corrected under continuous conveying. After the correction is completed, the first contact 231 and the second contact 242 are disconnected, and the telescopic rod 26 is powered off, and then returns to the initial position. At this time, the supporting roller 2321 is in a horizontal state, and the layered product can be rolled normally.

[0083] Specifically, there is a certain distance between the first contact point 231 and the second contact point 242, which is set to 2-3mm. When the steel belt 12 deviates by a certain amount, the first contact point 231 contacts the second contact point 242 after the steel belt 12 deviates by 2mm, and then the telescopic rod 26 starts to move upward, that is, it can drive the connected second connecting block 23 to move upward, and then make the supporting pressure roller 2321 move upward, that is, the supporting pressure roller 2321 tilts, so that the steel belt 12 moves in the direction away from the side contact roller 24, and the deviation can be corrected.

[0084] When the present invention is used, first, the device is installed at a position such as Figure 1 and Figure 3The steel belt 12 is positioned between the pressing roller 22 and the supporting pressing roller 2321, and then during use at home, the lower belt surface of the steel belt 12 contacts the supporting pressing roller 2321. During normal guidance, the elastic slider 25 is in the first state, and is in elastic contact with the belt surface of the steel belt 12 to press the belt surface. Then, in conjunction with the passive deviation correction mechanism, if the edge of the steel belt 12 is warped or uneven, the elastic slider 25 will be driven to move upward, that is, the connected pressing roller 22 will be driven to move upward synchronously. During the upward movement, the extrusion inclined surface 421 on the extrusion inclined block 42 will be squeezed. Due to the setting of its extrusion inclined surface 421, the extrusion inclined surface 421 is then driven to move in the direction away from the elastic slider 25, that is, the locking rod 43 is squeezed by the action of the guide column 422 and the inclined groove 431, so that the locking rod 43 is separated from the sliding block 41, that is, at this time the sliding block 41 is unlocked, and then moves a distance in the direction close to the elastic slider 25, but the notch of the limiting lock groove 251 at this time does not correspond to it, and then, after passing through the unevenness, the elastic slider 25 moves downward under the elastic force of the second elastic member 2111 and the third elastic member 2121, that is, at this time the notch of the limiting lock groove 251 is aligned with the sliding block 4 1, and then the sliding block 41 is inserted into the limiting lock groove 251 under the elastic force of the fourth elastic member 412, and then the elastic slider 25 will not move upward any more, and will be in a state of rigid contact with the belt surface, that is, when passing through the above-mentioned warping edge again, the pressing roller 22 at this time will not move upward any more, that is, the steel belt 12 at this position can be rigidly pressed, that is, the present invention uses the elastic slider 25 that is movably arranged, and then sets the pressing roller 22 on the elastic slider 25. During normal use, the steel belt 12 can be limited and squeezed by the elastic contact of the pressing roller 22, and the elastic contact can be on the steel belt 1 When the deviation of the belt surface is corrected, the wear on the belt surface of the steel belt 12 is reduced. At the same time, when the edge of the steel belt 12 is warped, the elastic slider 25 can be triggered by the passive locking member 4, so that the elastic slider 25 and the belt surface of the steel belt 12 are in rigid contact in the second state, that is, not only can the elastic edge pressing of the belt surface of the steel belt 12 be achieved in normal times, but also when warping occurs, the pressing roller 22 can cooperate with the supporting pressing roller 2321 to rigidly squeeze the belt surface of the steel belt 12, so that it can be used to flatten the steel belt 12, greatly improving the efficiency of flattening the steel belt 12 and improving the flatness and uniformity of the layered plate product.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
