Detailed Description
In the prior art, a synchronous belt for conveying a tread is arranged on a tread feeding frame, the synchronous belt is generally horizontally arranged, the tread is arranged on the upper surface of the synchronous belt, and the tread moves along with the synchronous belt, and it is worth noting that the tread cannot generally completely cover the synchronous belt in the width direction, namely, a part of the tread is uncovered on two sides of the synchronous belt.
The heating device for heating the tread is arranged above the synchronous belt, the heating device comprises a heating component 2, a support 1 can be arranged on a tread feeding frame for conveniently installing the heating component 2 as shown in fig. 1, the support 1 comprises two vertical plates 11 which are arranged left and right, the two vertical plates 11 are respectively arranged on the left side and the right side of the feeding frame, the heating component 2 is arranged above the two vertical plates 11, and obviously, the support 1 only needs to fix the heating component 2 above the synchronous belt, and the specific form is not limited.
As shown in fig. 1 and 2, the heating assembly 2 includes a radiation heating element (not shown) and a reflecting cover 21, where the radiation heating element heats by emitting heat radiation outwards, for example, an infrared lamp may be used as the radiation heating element, and the heat radiation at this time is infrared light, which is taken as an example in this embodiment. The reflecting cover 21 is arranged outside the radiation heating element, the lower part of the reflecting cover 21 is provided with an opening 22, and the heat radiation emitted by the radiation heating element is emitted from the reflecting cover 21 through the opening 22 and finally is directed to the tread below the opening 22, so that the temperature of the tread is increased.
Specifically, when the radiation heating element employs an infrared lamp, infrared light from the infrared lamp is emitted directly or indirectly (reflected by the reflecting cover 21) from the opening 22, thereby heating the tread below.
As shown in fig. 2, the reflecting cover 21 is provided with at least a top surface 211, a front surface 212, a rear surface 213, a left side surface 214, and a right side surface 215, and an opening 22 is formed below the reflecting cover 21, so that infrared light emitted from the infrared lamp can be emitted only from the opening 22 below.
In general, in order to ensure the heating effect, i.e. the quality of the tread being heated, the width of the heating assembly 2 needs to be equal to or greater than the width of the tread, more precisely, the width of the opening 22 is generally equal to or greater than the width of the tread, so that the heat can cover the whole width of the tread during heating, but at the same time, the positions of the two sides of the synchronous belt, which are not covered by the tread, are heated, so as to avoid damage to the synchronous belt.
As shown in fig. 1, 5 and 6, a protection device for heating a tread joint is provided below the opening 22 to block heat radiation on both left and right sides of the opening 22, thereby preventing damage to both sides of the timing belt due to heating.
As shown in fig. 2, the apparatus includes left and right reflecting plates 3 and 4, respectively, the left and right reflecting plates 3 and 4 are disposed at left and right sides below the opening 22 of the reflecting cover 21, and the left and right reflecting plates 3 and 4 face the opening 22, i.e., the left and right reflecting plates 3 and 4 face the heating surface, so as to secure a sufficient blocking effect. An intermediate channel 5 for infrared light to pass through is reserved between the left reflecting plate 3 and the right reflecting plate 4, and the left reflecting plate 3 and the right reflecting plate 4 are used for blocking and reflecting infrared light on two sides of the reflecting cover 21, so that heat radiation is prevented from being directly absorbed by a synchronous belt below, and the synchronous belt is protected.
In one embodiment, the left and right reflecting plates 3 and 4 are two horizontally disposed plates, and the outer ends of the left and right reflecting plates 3 and 4 are located at least at the outer ends of the opening 22, so that infrared light on the left and right sides of the opening 22 can be blocked by the left and right reflecting plates 3 and 4, respectively, while middle infrared light can be irradiated on the tread through the middle channel 5.
In another embodiment, as shown in fig. 2, the left and right reflecting plates 3 and 4 are two obliquely arranged plates, and the left and right reflecting plates 3 and 4 and the radiated light form an angle of 30-45 °. Specifically, the heights of the upper outer ends of the left and right reflection plates 3 and 4 are higher than the inner ends. More precisely, the left end of the left reflecting plate 3 is higher than the right end, and the right end of the right reflecting plate 4 is higher than the left end. This can make a portion of heat radiation shine after the up end of left reflecting plate 3 and right reflecting plate 4, can take place the reflection to in the partial heat radiation after the reflection will get into intermediate channel 5, when guaranteeing not damaging the hold-in range, with the heat radiation emission to the centre on both sides, thereby improved the utilization ratio of energy, promoted the heating effect, shortened the heating time.

As shown in fig. 4, when the infrared light irradiates downward from above the reflecting plate, the infrared light first contacts the upper surface of the reflecting plate, but cannot directly irradiate downward on the tread, and the infrared light must be reflected in the left reflecting channel 31 or the right reflecting channel 41 before the infrared light irradiates the tread below.
Specifically, taking the left reflecting plate 3 as an example, in the horizontal direction, the left end 301 of the left reflecting plate 3 is at least aligned with the right end 302 of the adjacent left reflecting plate 3, and it is preferable that the left end 301 can extend to the left of the right end 302 of the other left reflecting plate.
As shown in fig. 5 and 6, the left reflection channel 31 and the right reflection channel 41 are both inclined channels, when the infrared light irradiates downward, the infrared light contacts with the upper end surface of the reflection plate first, then is reflected, and part of the reflected infrared light contacts with the lower end surface of the reflection plate positioned at the inner side, so that the infrared light continuously reflects in the inclined channels and moves downward until being emitted from the lower part of the channels, so that the infrared light at two sides can be gathered through the inclined channels while being blocked, and finally is emitted to the tread, thus further improving the utilization rate of energy and the heating effect.
The left and right reflection plates 3, 4 each include inclined portions 33, 43 provided obliquely and horizontal portions 34, 44 provided horizontally, the horizontal portions 34, 44 being located at lower portions of the inclined portions 33, 43. The upper end point of the previous inclined portion is aligned with the lower end point of the next inclined portion.

The adjustment assembly 6 may be mounted on the bracket 1, thereby securing the adjustment assembly 6.
Specifically, the adjusting component 6 may be a bidirectional screw, where the left reflecting plate 3 and the right reflecting plate 4 are respectively disposed at two different output positions (for example, two different nuts) on the bidirectional screw, and when the bidirectional screw is driven to move, the left reflecting plate 3 and the right reflecting plate 4 are close to each other or far away from each other. In addition, the adjusting component 6 can also be provided with two independent unidirectional screw rods, the left reflecting plate 3 and the right reflecting plate 4 are respectively arranged on one unidirectional screw rod, the unidirectional screw rods are respectively driven to move, and the left reflecting plate 3 and the right reflecting plate 4 can be respectively controlled to move. Because the screw rod needs to operate at high temperature, the high temperature state is ensured to be used and lubricated by adopting high-temperature resistant Wen Sigan and grease.
