Description

Technical Field

[0001] The utility model relates to the technical field of composite plate cutting and milling equipment, in particular to an automatic adjustment device for composite plate cotton strip edge milling guide. Background Art

[0002] In the production and manufacturing process of rock wool composite panels, a relatively mature production line has been formed in the prior art. In the production line, it generally includes a rock wool board feeding and conveying device, a rock wool board strip cutting device and a rock wool board edge milling device. The rock wool board feeding and conveying device conveys the whole rock wool board to the rock wool board strip cutting device, the rock wool board strip cutting device cuts the whole rock wool board into rock wool strip groups, and conveys the rock wool strip groups to the rock wool edge milling device through a roller conveyor, and the rock wool board edge milling device mills the edges of each strip of the rock wool strip group.

[0003] The milling of the rock wool strip group is a very important process. The milling of the rock wool strip group can achieve the required shape and then achieve the purpose of reasonable combination with the upper and lower steel plates. After the rock wool strip group is milled, the accurate shape and width dimensions must be ensured. The milling of the rock wool strip group is a very important process in the processing of the composite board and plays a decisive role in the quality of the board. The conventional operation method on the current production line is to use a fixed guide adjustment device, which is fixed on both sides of the roller bottom plate through two L-shaped bending parts, and the rock wool strip group is located between the two L-shaped bending parts. Due to the processing error of the raw material sliver width, the accumulated error after the sliver combination is large, and the fixed guide adjustment device cannot play the role of clamping the sliver group. There is a gap between the sliver groups. When the sliver group with a gap enters the milling device, it is pressed by the pressing roller of the milling device, and the milling is cut by multiple milling saws of the milling device. Since the spacing between the milling saws is fixed, this will cause the width of the sliver group after milling to change greatly, which will lead to poor appearance and thermal insulation performance of the product.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1-4 As shown, a composite board cotton strip edge milling guide automatic adjustment device includes a frame 1, a cylinder 3 and a baffle 4.

[0028] The frame 1 is welded by two vertical legs and a crossbeam, and the frame 1 is arranged between the rock wool board cutting device and the rock wool board milling device;

[0029] The two cylinders 3 are symmetrically mounted on the two outer sides of the frame 1 through the cylinder fixing seat 2. In this embodiment, the cylinder fixing seat 2 is a square plate, and the cylinder fixing seat 2 can be directly mounted above the crossbeam of the frame 1. The cylinder fixing seat 2 is provided with a long hole, and the frame 1 is provided with a threaded hole. The cylinder fixing seat is fixed by bolts passing through the long holes and the threaded holes. The position of the cylinder fixing seat 2 on the frame 1 can be adjusted through the long holes to adjust the position of the cylinder 3. It is suitable for rock wool strip groups of various widths and sizes, and the push rod of the cylinder 3 faces the inner side of the frame 1.

[0030] Preferably, the cylinder 3 described in this embodiment is a three-axis cylinder.

[0031] like Figure 3 As shown, the two baffles 4 are fixedly mounted on the push rod of the cylinder 3, the two baffles 4 are vertically arranged, and the length direction of the baffles 4 is consistent with the running direction of the roller of the rock wool board cutting equipment. Figure 3 The front end of the roller conveyor at the bottom is inclined toward the outside of the frame 1, and the rear end of the baffle plate 4 is parallel to the running direction of the roller conveyor. This design facilitates the folding of the rock wool strip group.

[0032] An air filter 5 and a pressure reducing valve 6 are sequentially connected in series between the cylinder 3 and the air source. The pressure reducing valve 6 and the air filter 5 form a constant pressure air source for the cylinder 3 so that the push rod of the cylinder 3 maintains a constant thrust.

[0033] The air filter 5 and the pressure reducing valve 6 form an air filter pressure reducing valve 6, which belongs to a pilot piston type pressure reducing valve 6. It consists of two parts: a main valve and a pilot valve. The main valve is mainly composed of a valve seat, a main valve disc, a piston, a spring and other parts. The pilot valve is mainly composed of a valve seat, a valve disc, a diaphragm, a spring, an adjusting spring and other parts. The outlet pressure is set by adjusting the adjusting spring pressure, the outlet pressure change is sensed by the diaphragm, and the size of the flow area of ​​the main valve throttling part is adjusted by opening and closing the pilot valve to drive the piston, so as to realize the pressure reducing and stabilizing function.

[0034] A transition plate 15 is arranged above the frame 1, and the length direction of the transition plate 15 is consistent with the length direction of the frame 1. The transition plate 15 is used as an extension of the roller of the rock wool board cutting device to prevent the front end of the rock wool strip group from sinking due to gravity and being unable to maintain a clamped state to enter the rock wool board milling device.

[0035] Example 2

[0036] This embodiment is based on Embodiment 1, and a further solution is that two screw mounting seats 17 are provided on the frame 1, and screws 10 are rotatably connected to the two screw mounting seats 17, and the radial direction of the screw 10 is consistent with the width direction of the frame 1. The two screws 10 are symmetrically arranged along the center line of the frame 1, and guide rails 9 are provided on the sides of the frame 1. Slide blocks 8 are installed on the two screws 10, and the slide blocks 8 cooperate with the guide rails 9. Slide block fixing seats 7 are fixed on the two slide blocks 8, and the cylinder fixing seat 2 is detachably connected to the slide block fixing seat 7. The rotation of the screw 10 makes the slide block 8 move along the guide rail 9 to drive the cylinder fixing seat 2 on the slide block fixing seat 7 to move. The rotation of the screw 10 can be controlled by a turntable, so as to adjust the position of the cylinder 3. The technical solution makes the position adjustment of the cylinder 3 more convenient.

[0037] like Figure 4 As shown, the lead screw 10 , guide rail 9 , slider 8 and slider fixing seat 7 are arranged on the side of the frame 1 .

[0038] A further solution of the utility model is that a stepper motor 12 is arranged on the side of the frame 1, a driven wheel 11 is arranged at the end of the lead screw 10, a driving wheel 13 is installed on the motor shaft of the stepper motor 12, the driving wheel 13 and the driven wheel 11 are connected by a synchronous belt, and the position of the cylinder 3 can be automatically adjusted by the stepper motor 12 according to the width of the rock wool strip group, and the adjusted position is more precise.

[0039] According to the above embodiment, the guide automatic adjustment device is installed between the rock wool board cutting device and the rock wool board milling device. The rock wool board cutting device cuts the rock wool board into a rock wool strip group 14. The rock wool strip group is transported to the guide automatic adjustment device via the roller 16. First, according to the width of the rock wool board, the position of the baffle 4 is adjusted by the stepper motor 12. The guide automatic adjustment device precisely controls the thrust of the cylinder 3 through the air filter 5 and the pressure reducing valve 6. The rock wool strip group passes above the transition plate 15. When the width of the rock wool strip group is large, the baffle 4 is squeezed. At this time, the pressure of the pressure reducing valve 6 increases. Since the pressure of the pressure reducing valve 6 is constant at 0.2kpa, the pressure reducing valve 6 releases the pressure to adjust the output pressure. The cylinder 3 retracts, driving the baffle 4 to move away from the rock wool strip board, avoiding excessive squeezing force of the moving baffle 4 on the rock wool strip group, so that the rock wool strip group cannot move on the roller below. On the contrary, when the width of the rock wool strip group is small, the pressure reducing valve 6 increases the pressure to make the telescopic rod drive the movable baffle 4 to move to the side close to the rock wool strip group until the pressure of the baffle 4 on the rock wool strip group is 0.2kpa, so as to avoid excessive gaps between multiple cotton strips. The cylinder 3 eliminates the gaps between multiple cotton strips by repeated expansion and contraction, thereby ensuring that the cotton strips are in close contact with each other, thereby realizing the control of the size of multiple cotton strips after overlapping, and achieving the purpose of good appearance effect and thermal insulation performance of the product.
