Description

Technical Field

[0001] The utility model relates to the technical field of plate purification, in particular to a front speed reduction device for plate impact buffering and a drying chamber. Background Art

[0002] Formaldehyde-containing glue is used in the manufacturing process of synthetic boards, and they need to be purified to remove formaldehyde before leaving the factory. The current purification method is usually to send the boards into a drying chamber and use a high temperature environment to promote and enhance discharge.

[0003] At present, the use of drying chambers and drying racks can realize transfer and drying at the same time. The feeding direction of the large-sized drying chamber is consistent with the conveying direction of the drying rack, but for small-sized strip plates, due to their shape characteristics, their feeding direction is perpendicular to the drying rack. In the drying chamber for small-sized plates, since the matching drying rack needs to transfer the plates, its feeding structure usually adopts multiple roller bodies arranged in parallel, and the roller bodies and the drying racks are staggered. After the plates are sent to the feeding port of the chamber by the conveyor belt, they are sent into the chamber under the action of inertia and the support of the roller bodies.

[0004] However, in order to ensure that the small-sized strip plates can completely enter the cabin, it is necessary to ensure that the plates have a certain initial velocity, which will cause the plates to hit the cabin and rebound, and then the material will be stuck due to the difference in rebound distance. In order to solve this problem, Figure 1 As shown, the current technical route is to set an impact buffer mechanism on the inner wall of the cabin. After the plate enters the cabin, the impact buffer mechanism is used to unload energy, which can effectively reduce the frequency of plate jamming. However, this still cannot solve the problems caused by the large initial impact velocity of the plate, the loud impact noise, and the plate completely unloading energy through hard contact with the impact buffer mechanism, which may cause damage to the inside of the layered laminated plate.

[0005] Based on this, the inventor designed a front speed reduction device and a drying chamber for plate impact buffering on the original basis to solve the above problems, and thus proposed the present application. Utility Model Content

[0006] The purpose of this application is to provide a pre-speed reduction device and drying chamber for plate impact buffering, so as to solve the problems of large initial impact velocity of the plate, loud impact noise, and possible damage to the inside of the layered pressed plate due to complete energy unloading through hard contact.

[0007] In order to solve the above technical problems, the utility model adopts the following solutions:

[0008] One aspect of the present application provides a front deceleration device for plate impact buffering, comprising a plurality of roller bodies arranged in front of the impact buffering mechanism along the plate moving direction, and also comprising a deceleration cover arranged between two roller bodies and a supporting box plate for mounting the deceleration cover, wherein:

[0009] The speed reduction baffle cover comprises a mounting cover and an elastic baffle cap with a top height higher than the top height of the roller, and the elastic baffle cap is mounted on the top of the supporting box plate through the mounting cover.

[0010] Optionally, the elastic stop cap has a cavity inside, a plurality of air extraction holes are arranged on a side of the elastic stop cap facing away from the impact buffer mechanism, and an air extraction cavity communicating with the cavity is arranged in the support box plate;

[0011] It also includes an air pump and an air suction pipe. The air suction end of the air pump is connected to the air suction cavity of the supporting box plate through the air suction pipe.

[0012] Optionally, the method further includes a judgment sensor for detecting whether the plate has moved above the roller body, and a controller whose signal input terminal is electrically connected to the judgment sensor;

[0013] The signal output end of the controller is electrically connected to the air pump.

[0014] Optionally, the air extraction holes are distributed in a rectangular array in a top area of ​​the elastic blocking cap on a side facing away from the impact buffer mechanism.

[0015] Optionally, the elastic blocking cap is flat, the longitudinal sections of the middle and bottom are trapezoidal or rectangular, and the longitudinal section of the top is arc-shaped.

[0016] Optionally, the plurality of roller bodies are damping rollers, and the damping values ​​of the plurality of roller bodies along the moving direction of the plate increase gradually.

[0017] Optionally, the mounting cover is detachably fixedly connected to the top of the supporting box plate.

[0018] Optionally, the mounting cover is fixedly connected to the elastic stop cap;

[0019] The mounting cover is made of plastic, and the elastic stop cap is made of rubber or silicone material.

[0020] Another aspect of the present application provides a drying chamber, comprising any of the above-mentioned front deceleration devices for plate impact buffering, and also comprising a chamber body with a feed inlet and an impact buffering mechanism, wherein the impact buffering mechanism is arranged on a side wall of the chamber body opposite to the feed inlet;

[0021] The drum body is arranged between the impact buffer mechanism and the feed port;

[0022] At least two speed reduction shields are provided and are both located between the two roller bodies.

[0023] Optionally, the impact buffer mechanism includes a mounting plate disposed transversely on the side wall of the cabin, and an impact plate and an energy dissipation plate, wherein:

[0024] The impact plate is rotatably connected to the mounting plate, and its rotating shaft is horizontally arranged. The energy release plate is movably connected to the mounting plate. The energy release plate and the impact plate are parallel to each other, and the energy release plate is located on the side of the impact plate away from the drum body.

[0025] Beneficial effects of the utility model:

[0026] 1. The present application sets a supporting box plate and a speed reduction cover, and the top height of the elastic cap of the speed reduction cover is higher than the top height of the roller body, so that when the plate moves through the roller body, the plate can be pressed against the top of the elastic cap and crushed and deformed, so that the plate can reduce a part of its initial velocity through the friction between the plate and the elastic cap, and reduce the kinetic energy before the collision, thereby solving the current problems caused by the large initial velocity of the plate, the loud impact noise, and the possible damage to the inside of the layered laminated plate due to the plate completely unloading energy through hard contact.

[0027] 2. The present application sets a cavity inside the elastic baffle cap, sets an exhaust hole on the top of the side facing away from the impact buffer mechanism, and sets an exhaust pump and an exhaust pipe, so that after the plate collapses and deforms the elastic baffle cap, the plate can be pressed on the exhaust hole. Through the exhaust action of the exhaust pump, the deceleration effect of the elastic baffle cap on the plate can be further improved, and the kinetic energy of the plate before impact can be reduced.

[0028] 3. The present application provides a damping roller body, which can provide a certain blocking and deceleration effect for the plate when the roller body contacts the plate, thereby reducing the kinetic energy of the plate before impact. In particular, the damping value of the roller body gradually increases as it moves away from the feed port, which can prevent the plate from decreasing too quickly at the beginning of entering the cabin, resulting in its inability to get close to the impact buffer mechanism.

The judgment sensor 8 in this embodiment is a photoelectric sensor, and the controller 9 is a common PLC control board, which will not be described in detail here.

[0048] Specifically, in this embodiment, Figure 4As shown, the air extraction holes 512 are distributed in a rectangular array at the top area of ​​the elastic stop cap 51 on the side facing away from the impact buffer mechanism 3. The air extraction holes 512 are distributed in a rectangular array, which can improve the uniformity of force at each position of the plate, and the air extraction holes 512 are distributed in the top area of ​​the elastic stop cap 51, which can reduce the amount of air extracted from the air extraction holes 512 after the elastic stop cap 51 is collapsed by the plate.

[0054] Embodiment 2:

[0055] like Figure 5 As shown, based on the above embodiment 1, this embodiment provides a drying chamber, comprising any of the above-mentioned pre-speed reduction devices for plate impact buffering, and also comprising a chamber body 1 with a feed inlet and an impact buffer mechanism 3, wherein the impact buffer mechanism 3 is arranged on the side wall of the chamber body 1 opposite to the feed inlet;

[0056] The drum body 4 is arranged between the impact buffer mechanism 3 and the feed port;

[0057] At least two deceleration shields 5 are provided and are located between the two roller bodies 4. In this embodiment, the air pump 71 is connected only to the inner cavity 511 of the elastic shield 51 close to the impact buffer mechanism 3, thereby gradually increasing the resistance to the plate, preventing the plate from dissipating all kinetic energy before moving to the impact buffer mechanism 3, resulting in different final positions of the plate.

The energy unloading plate 31 and the impact plate 32 are parallel to each other, and the energy unloading plate 31 is located on the side of the impact plate 32 away from the drum body 4.

[0060] The energy unloading plate 31 in this embodiment is connected to the mounting plate 33 by means of a steel wire rope. After the plate hits the impact plate 32, the impact plate 32 swings toward the energy unloading plate 31 to hit the energy unloading plate 31. The energy unloading plate 31 swings again to hit the impact plate 32 in the reverse direction, so that the entire impact buffer mechanism 3 releases and consumes the energy transmitted from the plate during the impact.
