Description

Technical Field

[0001] The invention relates to a backing component with adaptive material width and a gantry steel plate sawing and milling miniature machine comprising the same. Background Art

[0002] For sawing machines or sawing beds for sawing steel plates, fixed backing is used in the process of clamping the master material before sawing. However, when feeding the fixed backing master material, the side of the master material often rubs against the fixed backing, resulting in much wear and poor passability of the master material. Patent with publication number CN208866844U: A backing for manually cutting the bevel of a steel plate, wherein a flange is sleeved at the central position of the upper half of a round steel, a threaded hole is opened on the left side of the flange, and a tightening bolt is provided in the threaded hole, and an external thread is tapped on the lower half of the round steel, a nut is screwed on the bottom end of the round steel, and a flange is welded on the right side of the flange, and a threaded hole is opened at the top of the flange, and a tightening bolt is provided in the threaded hole, and the flange is sleeved on the round steel. This prior art solves the problem of beveling the curved edge of the steel plate. Conventional cutting cannot guarantee the accuracy, quality and efficiency of the arc bevel cutting, and cannot meet the cutting process requirements. There is no technical improvement for this in the prior art. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects in the prior art and provide a backing assembly with adaptive material width. The movable backing and other parts connected to it can move left and right, can adapt to the material width when clamped, has less wear than a fixed backing, and has good masterbatch passability.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the present invention is to design a backrest assembly with adaptive material width, including a backrest arranged on the base of the feeding platform of the gantry steel plate sawing and milling mini machine, the backrest is slidably arranged on the base, and a clamping cylinder for clamping the masterbatch is also arranged on the base, and a clamping block is fixedly connected to the piston rod of the clamping cylinder, and the clamping block is arranged opposite to the backrest; a fixed backrest limiter is arranged on the side of the backrest away from the clamping block. The backrest is arranged to slide, so it can adapt to the material width, has less wear than a fixed backrest, and has good masterbatch passability. In addition, due to the sliding arrangement of the backrest, it can also avoid the situation where the masterbatch is damaged by friction with the backrest due to the unevenness of the side of some masterbatch.

[0005] A further technical solution is that the backrest assembly also includes a fixed return cylinder, the return cylinder is located on the side of the backrest away from the clamping block, and the limiter is located below the return cylinder; the exposed end of the piston rod of the return cylinder is facing the backrest. Since the feeding process and clamping process of the masterbatch are: the masterbatch is transported forward to the position where the clamping cylinder is located, the clamping cylinder is actuated, and the clamping block fixedly connected to the exposed end of the piston rod of the clamping cylinder clamps the masterbatch, and the other side of the masterbatch abuts against the backrest, and then the base of the feeding platform of the gantry steel plate sawing and milling mini machine is transported forward as a whole to the sawing position for sawing. Therefore, in the process of the clamping block clamping the masterbatch and the other side of the masterbatch abutting against the backrest, the masterbatch will be tilted due to the abutment and push of the clamping block. Although it can be straightened in the end (due to the joint action of the clamping block and the backrest), this process is first tilted and then straightened, so the masterbatch is severely rubbed. The setting of the return cylinder effectively reduces the occurrence of this situation. To a certain extent, the setting of the return cylinder plays a role in correcting the deviation, so the wear of the masterbatch is greatly reduced and the passability of the masterbatch is greatly improved.

[0006] A further technical solution is that a limit structure of a backrest is provided on the base, and two limit positions of the backrest sliding are realized through the limit structure and the limit member. The limit member is used to realize the backrest for the masterbatch to abut against, and the setting of the limit structure can determine the allowable offset of the position of the feeding platform close to the side of the backrest, that is, due to the setting of the limit structure, when the masterbatch is placed on the feeding platform, the allowable range of the distance between the side end face of the masterbatch and the side of the feeding platform is clarified.

[0007] A further technical solution is that the distance between the limiter and the backing can be adjusted to achieve the limit position of the backing according to the masterbatch of different widths;

[0008] The limiter is an adjustment screw fixedly mounted on the cylinder bracket; the cylinder bracket is fixedly connected to the base; the return cylinder is fixedly connected to the cylinder bracket; the height of the clamping block is consistent with the height of the backrest. The depth of the adjustment screw screwed into the cylinder bracket can be adjusted according to the different widths of the masterbatch to better adapt to masterbatch of different widths, thereby improving the adaptability of the backrest assembly.

[0009] A further technical solution is that the backrest includes a guide plate and a cylinder connection block fixedly connected to the guide plate, the limiting structure includes a side end surface of the base close to the cylinder bracket, the lower end of the cylinder connection block is arranged below the top surface of the base, and the cylinder connection block is located on the side of the base close to the cylinder bracket. Through such an arrangement, when the piston rod of the return cylinder extends, it pushes the guide plate and the cylinder connection block, and the cylinder connection block will be blocked by the side end surface of the base to limit the cylinder connection block (that is, limit the backrest). The movable backrest and other parts connected to it can move left and right, and can adapt to the material width when clamped, which is less wear-resistant than the fixed backrest, and has good masterbatch passability.

[0010] The present invention also provides a technical solution, which is a gantry steel plate sawing and milling small machine, including the backing assembly with adaptive material width. Although the name of the application is a sawing and milling machine, it is still a sawing machine or a sawing bed in essence, but the surface accuracy of the steel plate after sawing can reach the surface accuracy of milling, so the applicant calls it a sawing and milling machine, which means a sawing bed (or sawing machine) that can achieve the surface accuracy of milling. For details on how to achieve sawing accuracy to achieve milling accuracy, please refer to the patent with announcement number CN116372260B previously applied by the applicant.

[0011] The advantages and beneficial effects of the present invention are: the backing is set to slide, so it can adapt to the material width, less wear than a fixed backing, and good masterbatch passability. In addition, due to the sliding setting of the backing, it can also avoid the situation where some masterbatch is damaged by friction with the backing due to uneven sides of the masterbatch.

[0012] The feeding and clamping process of the masterbatch is as follows: the masterbatch is transported forward to the position where the clamping cylinder is located, and when the clamping cylinder is actuated, the clamping block fixedly connected to the exposed end of the piston rod of the clamping cylinder clamps the masterbatch, and the other side of the masterbatch abuts against the backer, and then the base of the feeding platform of the gantry steel plate sawing and milling machine is transported forward as a whole to the sawing position for sawing. Therefore, in the process of the clamping block clamping the masterbatch and the other side of the masterbatch abutting against the backer, the masterbatch will tilt due to the abutment and pushing of the clamping block. Although it can be straightened in the end (due to the joint action of the clamping block and the backer), this process is first tilted and then straightened, so the masterbatch is severely rubbed. The setting of the return cylinder effectively reduces the occurrence of this situation. To a certain extent, the setting of the return cylinder plays a role in correcting the deviation, so the wear of the masterbatch is greatly reduced, and the passability of the masterbatch is greatly improved.

[0013] The limiting member serves as a backrest for the masterbatch to rest against, and the setting of the limiting structure can determine the allowable deviation of the feeding platform on the side close to the backrest. That is, due to the setting of the limiting structure, when the masterbatch is placed on the feeding platform, the allowable range of the distance between the side end face of the masterbatch and the side surface of the feeding platform is clear.

[0014] The depth of the adjusting screw screwed into the cylinder bracket can be adjusted according to the different widths of the masterbatch to better adapt to the masterbatch of different widths, thereby improving the adaptability of the backing assembly.

[0015] The movable backing and other parts connected to it can move left and right, and can adapt to the material width when clamping, which has less wear than the fixed backing and good masterbatch passability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0052] Embodiment 1: Figures 1 to 10 As shown (for ease of illustration, Figure 1-Figure 9 The screw-nut mechanism is not shown; Figure 5 When the oil cylinder connecting block 9 is pressed against the adjusting screw 7 {or against the adjusting screw 7}; Figure 7When the oil cylinder connecting block 9 is pressed against the base 1 {or abutted against the base 1}), the present invention is an adaptive material width backrest assembly, including a backrest arranged on the base 1 of the feeding platform of the gantry steel plate sawing and milling mini machine, the backrest is slidably arranged on the base 1, and a clamping oil cylinder 3 for clamping the mother material 2 is also arranged on the base 1, and a clamping block 4 is fixedly connected to the piston rod of the clamping oil cylinder 3, and the clamping block 4 is arranged opposite to the backrest; a fixed backrest limiting piece is provided on the side of the backrest away from the clamping block 4. The backrest assembly also includes a fixed return cylinder 5, the return cylinder 5 is located on the side of the backrest away from the clamping block 4, and the limiting piece is located below the return cylinder 5; the exposed end of the piston rod of the return cylinder 5 is facing the backrest. A limiting structure of the backrest is provided on the base 1, and two extreme positions of the sliding of the backrest are realized by the limiting structure and the limiting piece. The setting of the limiting structure can determine the allowable offset 10 of the position of the feeding platform close to the side of the backrest; that is, due to the setting of the limiting structure, when the masterbatch 2 is placed on the feeding platform, the allowable range of the distance between the side end face of the masterbatch and the side of the feeding platform is clear. The distance between the limiting member and the backrest is adjustable to adjust the extreme position of the backrest according to the masterbatch 2 of different widths; the limiting member is an adjustment screw 7 fixedly set on the cylinder bracket 6; the cylinder bracket 6 is fixedly connected to the base 1; the return cylinder 5 is fixedly connected to the cylinder bracket 6; the height of the clamping block 4 is consistent with the height of the backrest. The backrest includes a guide plate 8 and a cylinder connecting block 9 fixedly connected to the guide plate 8, the limiting structure includes a side end face of the base 1 close to the cylinder bracket 6, the lower end of the cylinder connecting block 9 is set lower than the top surface of the base 1, and the cylinder connecting block 9 is located on the side of the base 1 close to the cylinder bracket 6. A screw nut seat 11 is fixedly arranged at the bottom of the base 1, and the nut of the screw nut mechanism 13 is fixedly connected to the screw nut seat 11, so that when the screw nut mechanism is in motion, it can drive the base and the clamped mother material above the base to move together, and after moving to the position where sawing is required, the steel plate (i.e., mother material) is sawed. Correspondingly, linear rails and linear rail sliders 12 are arranged on both sides of the screw nut seat 11 below the base 1 to facilitate the movement of the base driven by the screw nut mechanism.

[0053] The small gantry steel plate sawing and milling machine comprises the backing component with adaptive material width.

[0054] Here’s how it works:

[0055] The masterbatch is transported forward to the position where the clamping cylinder is located. The clamping cylinder is actuated and the return cylinder is also actuated at the same time (the clamping block fixedly connected to the exposed end of the piston rod of the clamping cylinder abuts against the masterbatch, and the other side of the masterbatch abuts against the left end of the movable backer due to the action of the return cylinder). This can ensure that the masterbatch is straight and avoid the masterbatch tilting when only the clamping cylinder is actuated. The setting of the movable backer, in conjunction with the clamping cylinder and the return cylinder (the return cylinder cannot push past the clamping cylinder), the return cylinder is forced to return when the clamping cylinder continues to act. In this process, the masterbatch is kept in a straight state and moves horizontally to the movable backer and abuts against the adjusting screw. In this way, on the one hand, the material width can be adapted, and on the other hand, the tilting of the masterbatch during transportation caused by only setting the clamping cylinder can be avoided (because the clamping cylinder 3 is actuated, the masterbatch often appears in the following situation: the front end of the masterbatch {refers to the end of the masterbatch located at the clamping cylinder} tilts toward the backer, while the rear end of the masterbatch is still in a position similar to that when the material is discharged, such as Figures 11 to 13 After the masterbatch is clamped, the screw nut mechanism drives the base to move forward and transport it to the sawing position for sawing.

[0056] Embodiment 2: The difference from Embodiment 1 is that Figures 14 to 17 As shown, a reduction motor 14 is fixedly arranged on the guide plate 8, and a friction wheel 15 is fixedly arranged on the output shaft of the reduction motor 14; the height of the friction wheel 15 is consistent with the height of the masterbatch 2 (it is best that the middle height of the friction wheel 15 is exactly consistent with the middle height of the masterbatch 2); the reduction motor 14 is located above the friction wheel; the reduction motor 14 is fixedly connected to the side end surface of the guide plate 8 facing the masterbatch 2 through a connecting block 16.

[0057] The masterbatch 2 is transported forward to the position where the clamping cylinder 3 is located. The clamping cylinder 3 is actuated and the return cylinder 5 is also actuated. The return cylinder 5 is actuated so that the friction wheel 15 abuts against the masterbatch 2. After the friction wheel abuts against the masterbatch, the manual remote control reduction motor 14 is started so that the masterbatch 2 is driven forward (toward the sawing direction) by the rotation of the friction wheel 15. Since the return cylinder 5 cannot push the clamping cylinder 3, the return cylinder 5 is forced to return when the clamping cylinder 3 continues to move. However, during this process, the friction wheel 15 continues to rotate until the masterbatch 2 has been transported to the sawing position, and then the manual remote control reduction motor 14 is stopped. During this process, the masterbatch is kept in a straight state and moves horizontally to the movable backer to abut against the adjustment screw, thus completing the two actions of clamping and transporting the masterbatch to the sawing position. Further improvements to the backer assembly realize that the process of the clamping cylinder clamping the masterbatch to the backer also realizes that the masterbatch reaches the sawing position, eliminating the screw nut mechanism.

[0058] Embodiment 3: The difference from Embodiment 2 is that Figures 18 to 25As shown, a group of wedge-shaped sliders are provided at the side end surface of the clamping block 4 facing the masterbatch 2. The wedge-shaped slider group is composed of two wedge-shaped sliders arranged opposite to each other, and a rubber layer or a vacuum suction cup 17; the two wedge-shaped sliders arranged opposite to each other are respectively a first wedge-shaped slider 18 and a second wedge-shaped slider 19, and the first wedge-shaped slider 18 is fixedly connected to the side end surface of the clamping block 4 facing the masterbatch 2; the second wedge-shaped slider 19 is arranged against the side end surface of the masterbatch 2 (the side end surface of the masterbatch here refers to the side end surface of the masterbatch facing the clamping block 4), and the rubber layer or the vacuum suction cup 17 is fixedly arranged on the end surface of the second wedge-shaped slider 19 facing the masterbatch;

[0059] A roller 20 is arranged on the side end surface of the guide plate 8 facing the masterbatch 2 to ensure that the masterbatch 2 is smoothly and unhinderedly transported forward due to the cooperation of the wedge-shaped slider group and the clamping cylinder;

[0060] The masterbatch 2 is transported forward to the position where the clamping cylinder 3 is located. At the designed position (the specific position is based on the distance from the sawing position according to the initial transport position of the masterbatch, and the setting position of the second wedge slider can be calculated according to the slope of the wedge slider group, so as to ensure that the distance of the masterbatch transported forward after the clamping cylinder is actuated is exactly the distance from the sawing position at the beginning of the masterbatch), the second wedge slider is tightly pressed against the side end face of the masterbatch through the rubber layer or the vacuum suction cup, and the clamping cylinder 3 is actuated and the return cylinder 5 is also actuated at the same time. When the return cylinder 5 is actuated, the slide backing is moved toward the masterbatch When the side approaches, that is, the ball of the guide plate 8 abuts against the side end face of the masterbatch, the clamping cylinder is actuated, and the clamping block 4 drives the first wedge-shaped slider to approach the second wedge-shaped slider (until the first wedge-shaped slider 18 and the second wedge-shaped slider 19 are dislocated, and then the clamping cylinder continues to act, and the masterbatch is pushed to continue to translate through the first wedge-shaped slider 18 and the second wedge-shaped slider 19. In the process of pushing the masterbatch to continue to translate through the first wedge-shaped slider 18 and the second wedge-shaped slider 19, due to the shape setting of the first wedge-shaped slider 18 and the second wedge-shaped slider 19, the masterbatch can be pushed to translate smoothly and stably. Fig.25 As shown in the figure, due to the wedge-shaped slider group, the clamping cylinder simultaneously pushes the mother material forward (that is, transports it to the sawing position) when clamping, and the subsequent clamping cylinder continues to push the mother material and finally abuts against the backrest (that is, the side end face of the guide plate 8, and finally the sliding backrest also abuts against the adjusting screw).

[0061] By setting a group of wedge sliders on the backrest assembly, the master material can be simultaneously transported to the sawing position when the clamping cylinder is actuated, and the distance the master material is transported forward can be accurately guaranteed by setting the initial position of the master material, the slope of the first wedge slider (or the second wedge slider) of the wedge slider group, and the position of the second wedge slider. In this way, the master material can be simultaneously transported to the sawing position during the clamping process without the need for other driving mechanisms; and the transport distance is also accurate.

[0062] The backing assembly realizes the process of clamping the mother material to the backing by the clamping cylinder and simultaneously realizes the mother material reaching the sawing position, eliminating the screw nut mechanism (no screw nut mechanism is needed to drive the base to move forward and transport it to the sawing position), and no other driving mechanism is needed, thereby reducing energy consumption. The original clamping driving mechanism (clamping cylinder) is still used, and one driving mechanism has two driving functions (both for clamping and for transporting the steel plate mother material to the sawing position), thus streamlining the structure of the entire sawing and milling miniature machine, saving the required components, and further reducing the specifications of the gantry steel plate sawing and milling miniature machine. Compared with the existing technology, it is more miniaturized and reduces the cost of the sawing and milling miniature machine.

[0063] Embodiment 4: The difference from Embodiment 3 is that Figure 26 to Figure 32 As shown, a limiting rope 21 is fixedly connected to the center position of the upper surface of the first wedge-shaped slider 18 to ensure the accurate position of the mother material after it is transported to the sawing position. One end of the limiting rope 21 is fixedly connected to the center position of the upper surface of the first wedge-shaped slider 18, and the other end first passes over a corner of the mother material 2 (hooks on the protruding block 24 when passing) to reach the lower opening of the base 1 where the clamping cylinder 3 is located (the opening is set in the middle of the base 1, on the one hand, it is used to observe the movement of the piston rod of the clamping cylinder on the base, and on the other hand, it is convenient for the limiting rope 21 to pass through) and then passes from the second wedge-shaped The middle position of the lower surface of the slider 19 passes upward through the second wedge-shaped slider 19, then passes through the middle of the upper surface of the second wedge-shaped slider 19, and then passes through the position point 22 of the upper surface of the first wedge-shaped slider 18 to the position of the corresponding position point 22 of the lower surface of the first wedge-shaped slider 18, and is fixedly connected to a weight block 23 (due to the provision of the weight block 23, the limit rope 21 is always in a taut state, and the figure shows the slack state of the limit rope 21 for the sake of convenience; and due to the tautness of the limit rope 21, it will not cause motion interference to the piston rod of the clamping cylinder 3). A protruding block 24 is provided on the front end surface of the masterbatch (referring to the front end surface in the conveying direction of the masterbatch) and is attached to the masterbatch 2 through a rubber layer or a vacuum suction cup 17 to ensure the fixation of the position of the limit rope 21 after the wedge-shaped slider group is misaligned; Fig.32 It is a schematic diagram of the state after the wedge slider group is misplaced. It can be seen that at this time the limit rope is in another stretched state and the weight block 23 is tightly against the lower surface of the first wedge slider 18; the initial stretched state of the limit rope 21 is that the weight block 23 is a certain distance away from the lower surface of the first wedge slider 18, because the wedge slider group has not been misplaced at the beginning.

[0064] The line connecting the position point 22 and the center position of the upper surface of the aforementioned first wedge-shaped slider 18 is parallel to the height of the first wedge-shaped slider 18 of the right-angled trapezoid, and the distance between the position point 22 and the lower base of the right-angled trapezoid is one-third of the height of the right-angled trapezoid; the limiting rope 21 is a rope with a small tensile coefficient, such as a steel wire rope, a nylon rope or a high-strength fiber rope.

[0065] The action process is similar to that of Example 3, except that after the masterbatch 2 is transported forward to the position where the clamping cylinder 3 is located, the limit rope 21 is designed to pass over the top of a corner of the masterbatch 2 and then pass over the protruding block 24. The rest of the action process is consistent with that of Example 3. In this way, the setting of the limit rope can prevent the wedge-shaped slider group from causing the masterbatch to be transported forward with inertia. The setting of the limit rope can prevent it from continuing to move forward due to inertia and deviating from the required sawing position, thereby ensuring that the sawing position is transported in place and accurately (due to the determination of the positions of the position point 22, the limit rope, a total of three points on the first wedge-shaped slider and the second wedge-shaped slider, and the determination of the position of the protruding block 24, as well as the determination of the initial position of the masterbatch, that is, the masterbatch is transported forward to the position where the clamping cylinder 3 is located, and the setting of the length of the limit rope, the size and slope of the wedge-shaped slider group can be accurately set to ensure that the masterbatch is also transported to the desired position at the end of the clamping process).

[0066] Embodiment 5: The difference from Embodiment 4 is that Fig.33 , Fig.34 As shown (for ease of illustration, Fig.34 The electromagnet, pulley and rope are not shown). A photoelectric sensor 25 for ensuring the accurate conveying position of the masterbatch is provided on the outside of the base, i.e., on one side of the masterbatch conveying direction. The connecting line between the transmitting head and the receiving head of the photoelectric sensor is parallel to the front end surface of the masterbatch. The photoelectric sensor 25 is connected to the controller 26 by signal. The controller 26 is connected to the electromagnet 27 fixedly arranged above the clamping block 4 by signal. A ferromagnetic block is provided corresponding to the electromagnet 27. The ferromagnetic block is arranged above the clamping block and beside the electromagnet 27, and the ferromagnetic block is fixedly connected to the rope 28. The rope 28 is wound on the rope groove of the pulley 29. The axle of the pulley 29 is fixedly connected to the roller axle of one of the rollers 30 in a row of roller groups supporting the masterbatch through a connecting shaft (a roller group is provided on one side of the base 1, and the uppermost horizontal plane of the roller group is slightly lower than the middle height of the clamping block 4 on the piston rod of the clamping cylinder 3 on the base, so that the masterbatch is at the middle height of the clamping block when it is conveyed to the roller group and to the clamping cylinder for easy clamping).

[0067] The master material 2 is transported forward to the position where the clamping cylinder 3 is located. The clamping cylinder 3 is actuated and the return cylinder 5 is also actuated at the same time. The return cylinder 5 slides to the side of the master material, that is, the ball of the guide plate 8 is against the side end face of the master material. The clamping cylinder is actuated and the clamping block 4 drives the rope 28 to rotate, which drives the pulley 29 to rotate, and then drives the roller 30 to rotate, so that the master material is transported forward (that is, transported to the sawing place) when the clamping cylinder 3 is actuated, and the setting of the ball facilitates the transportation of the master material. When the photoelectric sensor 25 receives a signal after reaching the sawing place, the controller sends a signal to cut off the power of the electromagnet 27 (that is, the electromagnet is energized at the beginning, and the electromagnet is placed in a state of being energized). The ferromagnetic block next to it is driven due to the suction force of the electromagnet; after power failure, since the mother material itself has a long length and a large mass, after the electromagnet 27 is powered off, the roller cannot rotate due to the pressure of the mother material, and the ferromagnetic block can only slide on the upper surface of the clamping block 4, and the friction force of the ferromagnetic block is not enough to make the pulley rotate, so the roller can no longer rotate. In order to prevent the ferromagnetic block from falling off the clamping block 4 and detaching from the clamping block 4, a circle of baffles can be set on the edge of the upper surface of the clamping block 4), then the rope is no longer pulled, and the roller no longer rotates, and the subsequent clamping cylinder continues to push the mother material and finally abuts against the backing (that is, the side end face of the guide plate 8, and finally the sliding backing also abuts against the adjusting screw).

[0068] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.

The backing component with adaptive material width is characterized by: The invention comprises a backrest arranged on the base of the feeding platform of the gantry steel plate sawing and milling small machine, the backrest is slidably arranged on the base, a clamping oil cylinder for clamping the mother material is also arranged on the base, a clamping block is fixedly connected to the piston rod of the clamping oil cylinder, and the clamping block is arranged opposite to the backrest; a fixed backrest limiter is arranged on the side of the backrest away from the clamping block; The backrest assembly also includes a fixed return cylinder, which is located on the side of the backrest away from the clamping block, and the limiter is located below the return cylinder; the exposed end of the piston rod of the return cylinder is facing the backrest; The base is provided with a limit structure of the backrest, and two limit positions of the backrest sliding are achieved through the limit structure and the limit member; The distance between the limiter and the backing is adjustable to adjust the limit position of the backing according to the masterbatch of different widths; The limiter is an adjustment screw fixedly arranged on the cylinder bracket; the cylinder bracket is fixedly connected to the base; the return cylinder is fixedly connected to the cylinder bracket; the height of the clamping block is consistent with the height of the backrest; The backrest includes a guide plate and a cylinder connection block fixedly connected to the guide plate, the limiting structure includes an end surface of the base close to the cylinder bracket, the lower end of the cylinder connection block is arranged below the top surface of the base, and the cylinder connection block is located on one side of the base close to the cylinder bracket; A group of wedge-shaped sliders is provided at the side end surface of the clamping block facing the masterbatch; the wedge-shaped slider group is composed of two wedge-shaped sliders arranged opposite to each other, a rubber layer or a vacuum suction cup; the two wedge-shaped sliders arranged opposite to each other are respectively a first wedge-shaped slider and a second wedge-shaped slider, the first wedge-shaped slider is fixedly connected to the side end surface of the clamping block facing the masterbatch; the second wedge-shaped slider is arranged against the side end surface of the masterbatch facing the clamping block, and the rubber layer or the vacuum suction cup is fixedly arranged on the end surface of the second wedge-shaped slider facing the masterbatch; Rollers are arranged on the side end surface of the guide plate facing the masterbatch to ensure that the masterbatch is smoothly and unhinderedly transported forward due to the cooperation of the wedge-shaped slider group and the clamping cylinder; The method for using the backing assembly is as follows: before conveying, the distance from the sawing position can be known according to the initial conveying position of the mother material, and then the setting position of the second wedge slider can be calculated according to the slope of the wedge slider of the wedge slider group, so as to ensure that the distance the mother material is conveyed forward after the clamping cylinder is actuated is exactly the distance from the sawing position at the beginning of the mother material; the mother material is conveyed forward to the position where the clamping cylinder is located, and the second wedge slider is tightly pressed against the side end surface of the mother material through the rubber layer or the vacuum suction cup at the designed position, the clamping cylinder is actuated and the return cylinder is also actuated at the same time, and the return cylinder is actuated to slide the backing closer to the side of the mother material, that is, the rolling of the guide plate When the bead abuts against the side end face of the mother material, the clamping cylinder is actuated and the clamping block drives the first wedge-shaped slider to approach the second wedge-shaped slider until the first wedge-shaped slider and the second wedge-shaped slider are misaligned. Then the clamping cylinder continues to actuate and the mother material is pushed to continue to translate through the first wedge-shaped slider and the second wedge-shaped slider. In the process of pushing the mother material to continue to translate through the first wedge-shaped slider and the second wedge-shaped slider, due to the shape setting of the first wedge-shaped slider and the second wedge-shaped slider, the mother material can be pushed to translate smoothly and stably. Due to the wedge-shaped slider group, the clamping cylinder simultaneously pushes the mother material to be transported to the sawing place when clamping. The subsequent clamping cylinder continues to push the mother material and finally abuts against the backing.

2. Gantry steel plate sawing and milling small machine, characterized in that: The invention comprises a backing component with adaptive material width as claimed in claim 1.
