The water supply tank 103 and the water diversion pipe 104 are fixedly installed on the base 101. A water film is formed between the water in the water supply tank 103 and the conveyor belt 102, and the conveying of the conveyor belt 102 is realized by the flowing water in the water supply tank 103, and the flow rate of the water in the water supply tank 103 is controlled by the water diversion pipe 104.

[0030] The conveying assembly also includes a conveying roller 106, a conveying roller 2 107, a conveying roller 3 108, a conveying roller 4 109, and an auxiliary roller 120 rotatably mounted on the base 101.

The tensioning roller 119 is rotatably mounted on the auxiliary slide 116. The base 101 An auxiliary screw rod 117 is rotatably installed on the upper part, an auxiliary motor 118 is fixedly installed on the base 101, the output shaft of the auxiliary motor 118 is fixedly connected to the auxiliary screw rod 117, the conveyor belt 102 is arranged on conveyor roller 106, conveyor roller 107, conveyor roller 3 108, conveyor roller 4 109, tensioning roller 119, and auxiliary roller 120, a conveying motor 105 is fixedly installed on the base 101, the output shaft of the conveying motor 105 is fixedly connected to the conveying roller 106, and the conveying motor 105 is started to drive the conveying roller 106 to rotate, so that the conveyor belt 102 moves.

[0031] Under the action of the tensioning roller 119 and the auxiliary roller 120, the part of the conveyor belt 102 located between the conveyor roller 2 107 and the conveyor roller 4 109 forms a Z shape, and the auxiliary motor 118 is started to drive the auxiliary screw 117 to rotate, so that the auxiliary slide 116 moves along the axis of the auxiliary screw 117, and the tensioning roller 119 moves synchronously. Under the action of the tensioning roller 119, the tension of the conveyor belt 102 on the conveyor roller 1 106, the conveyor roller 2 107, the conveyor roller 3 108, the conveyor roller 4 109, the tensioning roller 119 and the auxiliary roller 120 are adjusted.

[0032] Adjustment components are symmetrically arranged on the base 101, and the adjustment components include a T-shaped slide 112, and an adjustment rotating frame 113 is rotatably installed on the T-shaped slide 112. A self-locking unit is arranged between the adjustment rotating frame 113 and the corresponding T-shaped slide 112, and a plurality of adjustment rollers 114 are evenly rotatably installed on the adjustment rotating frame 113. The adjustment rollers 114 are used to adjust the V-shaped size formed by the conveyor belt 102. The V-shaped area formed by the conveyor belt 102 under the action of the adjustment rollers 114 is located on the inner side of the water supply tank 103.

[0033] A support assembly is provided on the base 101, and the support assembly includes a support slide 121. A plurality of support rollers 115 are evenly provided on the support slide 121. The support rollers 115 are used to support the conveyor belt 102. The support slide 121 is slidably installed on the water supply tank 103. The support rollers 115 are all located on the inner side of the water supply tank 103. A positioning screw rod 110 is rotatably installed on the water supply tank 103. The positioning screw rod 110 and the support slide 121 form a spiral pair. A positioning motor 139 is fixedly installed on the water supply tank 103, and the output shaft of the positioning motor 139 is fixedly connected to the positioning screw rod 110.

[0034] The positioning motor 139 is started to drive the positioning screw 110 to rotate, so that the support slide 121 moves up and down relative to the water supply tank 103, and the support roller 115 on the support slide 121 moves synchronously, that is, the position of the support roller 115 is adjusted.

[0035] The number of support rollers 115 is one less than the number of adjustment rollers 114 in a single positioning assembly. The support rollers 115 and the adjustment rollers 114 in a single positioning assembly are arranged at intervals. Water wheels 122 are fixedly installed at the ends of the adjustment rollers 114 and the support rollers 115. A plurality of driven water tanks 123 are arranged in a circumferential array on the adjustment rollers 114 and the support rollers 115. The water wheels 122 and the driven water tanks 123 are used to make the adjustment rollers 114 and the support rollers 115 rotate following the water flow in the water supply tank 103.

[0036] The two T-shaped slides 112 are symmetrically slidably installed on the base 101, and a double-headed threaded screw 135 is rotatably installed on the base 101. The threads at both ends of the double-headed threaded screw 135 respectively form a spiral pair with the corresponding T-shaped slide 112. A pitch-adjusting motor 136 is fixedly installed on the base 101, and the output shaft of the pitch-adjusting motor 136 is fixedly connected to the double-headed threaded screw 135. The pitch-adjusting motor 136 is started to drive the double-headed threaded screw 135 to rotate, so that the two T-shaped slides 112 move away from each other or move towards each other. A torsion spring is arranged between the adjusting rotating frame 113 and the T-shaped slide 112, one end of the torsion spring is fixedly connected to the T-shaped slide 112, and the other end of the torsion spring is fixedly connected to the adjusting rotating frame 113.

[0037] In the initial position, the torsion spring between the T-shaped slide 112 and the adjusting rotating frame 113 is not compressed, and the adjusting rotating frame 113 is in a vertical downward state relative to the T-shaped slide 112 .

[0038] The self-locking units each include two self-locking ratchets 132. The two self-locking ratchets 132 in the same self-locking unit are symmetrically fixed on both sides of the adjusting rotating frame 113. The axis of the self-locking ratchet 132 is in the same straight line as the center line of the rotation connection between the T-shaped slide 112 and the adjusting rotating frame 113. Self-locking ratchet rings 133 are symmetrically slidably installed on the T-shaped slide 112. Springs are provided between the self-locking ratchet rings 133 and the corresponding T-shaped slides 112. When the self-locking ratchet rings 133 are engaged with the corresponding self-locking ratchet 132, a ratchet mechanism is formed.

[0039] When in the initial position, the spring between the self-locking ratchet ring 133 and the corresponding T-shaped slide 112 is not compressed, and the self-locking ratchet ring 133 is engaged with the corresponding self-locking ratchet 132 to form a ratchet mechanism, driving the adjusting rotary frame 113 to rotate relative to the T-shaped slide 112, that is, the end of the adjusting roller 114 closest to the base 101 rotates in the direction away from the base 101. At this time, the self-locking ratchet 132 rotates relative to the self-locking ratchet ring 133, and the torsion spring between the adjusting rotary frame 113 and the T-shaped slide 112 is compressed, and the driving of the adjusting rotary frame 113 to rotate relative to the T-shaped slide 112 is stopped. Under the action of the self-locking ratchet 132 and the self-locking ratchet ring 133, the adjusting rotary frame 113 cannot rotate in the opposite direction, that is, under the action of the torsion spring between the T-shaped slide 112 and the adjusting rotary frame 113, the self-locking ratchet 132 and the self-locking ratchet ring 133, the position of the adjusting rotary frame 113 is restricted.

[0040] Separation push rods 131 are fixedly provided on the sides of the self-locking ratchet ring 133 , and separation inclined plates 134 are symmetrically provided on both sides of the base 101 . The separation push rods 131 and the separation inclined plates 134 are used to adjust the position of the self-locking ratchet ring 133 .

[0041] In the initial position, the separation push rod 131 does not contact the corresponding separation inclined plate 134, and the distance adjustment motor 136 is started to make the two T-shaped slides 112 move away from each other, and the separation push rods 131 corresponding to the T-shaped slide 112 move synchronously, so that the separation push rod 131 contacts the corresponding separation inclined plate 134, and the T-shaped slide 112 continues to move. Under the action of the separation inclined plate 134, the two separation push rods 131 on the same T-shaped slide 112 move away from each other, that is, the two self-locking ratchet rings 133 on the same T-shaped slide 112 move away from each other, and the spring between the self-locking ratchet ring 133 and the T-shaped slide 112 is compressed, which eventually causes the self-locking ratchet ring 133 to disengage from the self-locking ratchet 132, that is, the self-locking ratchet 132 and the self-locking ratchet ring 133 release the restriction on the position of the adjustment rotating frame 113.

[0042] A driven pulley 124 is fixedly installed on the adjusting rotating frame 113, and the axes of the driven pulley 124 and the self-locking ratchet 132 are in the same straight line. A transmission pulley 125, a linkage pulley 126, and a bevel gear 129 are rotatably installed on the T-shaped slide 112, and a transmission belt 128 is arranged between the driven pulley 124, the transmission pulley 125, and the linkage pulley 126. A limiting shaft 127 is also fixedly provided on the T-shaped slide 112, and the limiting shaft 127 is used to limit the position of the transmission belt 128. A bevel gear 2 130 is fixedly installed on the side of the linkage pulley 126, and the bevel gear 1 129 and the bevel gear 2 130 are meshed to form a gear pair. A spline long shaft 137 is rotatably installed on the base 101, and the bevel gear 1 129 forms a spline sliding fit with the spline long shaft 137. An adjusting motor 138 is fixedly installed on the base 101, and the output shaft of the adjusting motor 138 is fixedly connected to the spline long shaft 137.

[0043] When the two T-shaped slides 112 move relative to each other, the bevel gear 129 on the T-shaped slide 112 slides relative to the spline long shaft 137, and the adjusting motor 138 is started to drive the spline long shaft 137 to rotate. Since the bevel gear 129 and the spline long shaft 137 form a spline sliding fit, the bevel gear 129 rotates synchronously at this time. Under the action of the bevel gear 2 130, the interlocking pulleys 126 rotate, and the rotation directions of the two interlocking pulleys 126 are opposite. Under the action of the driven pulley 124, the transmission pulley 125, the limit shaft 127, and the transmission belt 128, the adjusting rotating frame 113 rotates synchronously, and the rotation directions of the two adjusting rotating frames 113 are opposite.

[0044] Working principle: According to the needs of conveying logistics, the distance adjustment motor 136 is first started to make the two T-shaped slides 112 move away from each other. Under the action of the separation push rod 131 and the separation inclined plate 134, the self-locking ratchet ring 133 releases the restriction on the rotation direction of the self-locking ratchet wheel 132. Then the adjustment motor 138 is started to drive the spline long shaft 137 to rotate, so that the two adjustment rotating frames 113 rotate, that is, the angle formed between the two relative adjustment rollers 114 is adjusted, and the distance adjustment motor 136 is started to adjust the two T The distance between the supporting slides 112 is adjusted, and finally, under the action of the adjusting roller 114, the portion of the conveyor belt 102 located between the conveyor roller 106 and the conveyor roller 3 108 forms the required V-shape, and then the auxiliary motor 118 is started to adjust the position of the tensioning roller 119, and the tensioning state of the conveyor belt 102 is adjusted as required, and then the positioning motor 139 is started to adjust the position of the supporting slide 121, so that the supporting roller 115 contacts the lower end of the V-shape of the conveyor belt 102 at this time, that is, the V-shaped position of the conveyor belt 102 is auxiliary supported.

[0045] Then, according to the conveying speed of the conveyor belt 102, the flow rate of water in the water supply tank 103 is controlled by the water pipe 104. One of the two water pipes 104 controls the speed at which water enters the water supply tank 103, and the other water pipe 104 controls the speed at which water flows out of the water supply tank 103, so that the flow rate of water in the water supply tank 103 is the same as the conveying speed of the conveyor belt 102. A water film is formed between the water in the water supply tank 103 and the conveyor belt 102, so that the water in the water supply tank 103 assists in conveying the conveyor belt 102. While the water in the water supply tank 103 flows, under the action of the water wheel 122 and the driven water tank 123, the adjusting roller 114 and the supporting roller 115 both rotate, so that the adjusting roller 114 and the supporting roller 115 assist in conveying the conveyor belt 102.
