In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
As used herein, the term "plurality" refers to an indefinite number of plural, usually more than two; and when the term "plurality" is used to indicate a quantity of a particular element, it does not indicate a quantitative relationship between such elements.
Referring to fig. 1-5, fig. 1 is a schematic structural view of an embodiment of a pipe belt machine provided by the present invention, fig. 2 is a schematic structural view of a conveyor belt, fig. 3 is a schematic structural view of a connection structure between a tubular belt and a support assembly and a coil, fig. 4 is a schematic structural view of a connection structure between a tubular belt and a support assembly, and fig. 5 is a schematic structural view of a braking device of a pipe belt machine provided by the present invention.
As shown in fig. 1 to 4, the present invention provides a braking device for a pipe belt machine, the pipe belt machine includes a conveying belt 1, the braking device includes: a plurality of wires 11 arranged at intervals on the conveyer belt 1, and when the conveyer belt 1 is wound into a tubular belt 1 ', two ends of each wire 11 are jointed to form a plurality of closed wire loops 11' arranged at intervals; a plurality of coils 2 are arranged at intervals, and each coil 2 is sleeved outside the tubular belt 1'; and a power supply 3, wherein when the brake device is started, the power supply 3 can supply power to the coil 2.
By adopting the structure, when braking is needed, the power supply 3 can be controlled to supply power to the coil 2 so as to generate current in the coil 2, a magnetic field can be generated around the coil 2 according to the principle of electromagnetic induction, and on the basis, when the tubular belt 1 'provided with the closed lead rings 11' runs in the coil 2, the magnetic flux in each closed lead ring 11 'can be changed so as to generate induction current in each closed lead ring 11', and the induction current can also generate an induction magnetic field.
According to lenz's law, the induced magnetic field generated by the induced current always hinders the change of the magnetic flux causing the induced current. When the wire loop 11 'approaches the coil 2, the magnetic flux induced by the magnetic field generated by the coil 2 in the wire loop 11' has an increasing tendency, and at this time, the induced magnetic field generated by the induced current in the wire loop 11 'can prevent the wire loop 11' from continuing to approach the coil 2; when the wire loop 11 ' is far away from the coil 2, the magnetic flux caused by the magnetic field generated by the coil 2 in the wire loop 11 ' has a weakening tendency, and at the moment, the induced magnetic field generated by the induced current in the wire loop 11 ' can prevent the wire loop 11 ' from being continuously far away from the coil 2, so that a ' leaving-resisting ' braking effect is generated on the closed wire loop 11 ', and the braking of the pipe belt machine is realized.
Since the number of the wire guiding loops 11 'is plural and the wire guiding loops are distributed at intervals in the extending direction of the tubular belt 1', the braking force generated by each wire guiding loop 11 'can be distributed at plural positions of the tubular belt 1', and the centralized setting of the braking force and the fire hazard caused by the breakage or the slippage of the conveyer belt 1 caused by the centralized setting of the braking force can be largely avoided.
Compared with the scheme of traditional mechanical braking, the braking device provided by the invention is simpler in structure and control and lower in cost, and when the braking is not carried out, the normal operation of the pipe belt conveyor cannot be influenced by the braking device.
The wire 11 and the conveyer belt 1 may be a split structure, and at this time, the wire 11 may be installed on the outer wall of the conveyer belt 1, and the specific installation process may be bonding or embedding. Alternatively, the wires 11 and the conveyor belt 1 may be of an integral structure, that is, the wires 11 are embedded in the conveyor belt 1 when the conveyor belt is installed.
Both ends of the wire 11 may be provided with conductive contacts 12, and the conductive contacts 12 may be embodied as metal contacts, and the wire 11 may be engaged by the conductive contacts 12 at both ends thereof when the conveyor belt 1 is wound to form the tubular belt 1'. The shape of the conductive contact 12 is not limited herein, and may be a sheet shape, or may be other shapes as long as the conveyor belt 1 can be joined by the conductive contact 12 when wound into the tubular belt 1'. In the embodiment of fig. 4, the conductive contacts 12 may be U-shaped and may be clamped to both lateral side edges of the conveyor belt 1, and in this case, the conductive contacts 12 may also serve to fix the wires 11 to some extent.
It should be noted that the conductive joints 12 are mainly provided to increase the area of the two ends of the conductive wire 11, so that when the conveyor belt 1 is wound to form the tubular belt 1', the two ends of the conductive wire 11 are more easily jointed to form a closed loop; however, the conductive contact 12 is not essential, or only one conductive contact 12 may be provided, as long as it is ensured that both ends of the wire 11 can be joined when the tubular band 1' is formed.
After the conveying belt 1 is wound to form the tubular belt 1 ', the loop surface where the formed wire loop 11' is located may be perpendicular to the extending direction of the conveying belt 1, or may not be perpendicular to the extending direction, which may be specifically set according to the actual situation. In the embodiment of the present invention, it is preferable to adopt a vertical scheme, so that the installation of the wires 11 can be easier, and when the installation is performed, the wires 11 are directly arranged to be vertical to the extending direction of the conveyor belt 1.
Here, the embodiment of the present invention does not limit the number of the conductive wires 11 disposed on the conveyor belt 1, the distance between two adjacent conductive wires 11, and the like, and each conductive wire 11 may be uniformly distributed or non-uniformly distributed, and may be specifically determined by combining actual conditions and the like.
The coils 2 may be independent of each other, and in this case, a plurality of power supplies 3 may be provided to configure one power supply 3 for each coil 2; of course, the same power supply 3 may be shared by a plurality of coils 2. Preferably, the embodiment of the present invention may adopt a scheme (as shown in fig. 1) in which only one power supply 3 is provided, and in this case, each coil 2 may be electrically connected, so as to reduce the number of power supplies 3 used and facilitate simplification of the structure of the braking device provided by the present invention; the coils 2 may be connected in series or in parallel, preferably in series, to simplify the connection structure.
The circuit formed by the power supply 3 and each coil 2 can be provided with an on-off switch which can be in signal connection with the controller 5, and when receiving a braking signal, the controller 5 can control the on-off switch to be closed so as to supply power to each coil 2.
With reference to fig. 5, the winding directions of two adjacent coils 2 may be opposite, so that the magnetic fields generated by the coils 2 may be independent from each other, and each coil 2 may exert a braking effect independently, which is more favorable for ensuring a braking effect. Of course, the winding directions of the coils 2 may also be the same, and at this time, the distance between two adjacent coils 2 may be controlled to avoid that the two adjacent coils 2 form a magnetic field to affect the braking performance; alternatively, a magnetic shielding member such as a metal plate or a metal mesh may be provided between the two adjacent coils 2, so that the two adjacent coils 2 are prevented from combining to form one magnetic field.
With continued reference to fig. 3, the pipe belt machine may further include a support assembly 4, the support assembly 4 may include a support plate 41 provided with a through hole and a plurality of idlers 42 mounted to the support plate 41, the number of coils 2 may be the same as the support assembly 4, and the coils 2 may be mounted to the support plate 41 of the support assembly 4 in a one-to-one correspondence. Of course, the number of coils 2 may be smaller than that of the support plate 41, and in this case, the coils 2 may be mounted on only a part of the support plate 41.
The invention also provides a pipe belt machine, which comprises a conveying belt and a braking device, wherein the braking device is the braking device of the pipe belt machine according to the above embodiments.
Since the above-mentioned brake device has the technical effects, the pipe belt machine having the brake device also has similar technical effects, and therefore, the detailed description thereof is omitted here.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
