DETAILED DESCRIPTION

[0023] In order to enable the person skilled in the art to better understand the utility model, the technical scheme of the utility model is further explained below in combination with the drawings and examples.

[0024] For example Figures 1-5The utility model discloses a plastic product conveying belt for packaging machine, including frame 1, be equipped with control panel in frame 1, frame 1 upper side is equipped with support plate 11, support plate 11 left and right sides are all rotationally equipped with transmission wheel 12, and transmission wheel 12 between transmission is equipped with conveying belt 13, and one transmission wheel 12 transmission is connected with drive mechanism, and support plate 11 left side is all connected with vertical rod 2, and two vertical rods 2 all are equipped with the chute 21 of opening to the up, and two chute 21 all are equipped with the support rod 22 of sliding up and down, and the detection mechanism is equipped between two support rods 22 upper sides, and two support rods 22 one end opposite side of extending into the chute 21 all are equipped with through -hole 23, and two through -hole 23 opposite sides all are equipped with mounting hole 24, and two mounting hole 24 opposite sides all are equipped with spring 25, and two spring 25 one end all are connected with sliding block 26, and two sliding blocks 26 one side all are equipped with the lock piece 27 of the through -hole 23 that can pass through, and two vertical rods 2 opposite sides all are equipped with a plurality of lock hole 28 matched with lock piece 27, and a plurality of lock hole 28 are from top to bottom and are equipped on the outer surface of vertical rod 2, and the pulling mechanism matched with two sliding blocks 26 is equipped between two support rods 22 upper ends.

[0025] The left side of the conveying belt is connected with the packaging machine. Through the external clamping mechanism, the plastic cover stack is dropped at the right end of the conveying belt 13. When the plastic cover stack is completed, in the process of conveying belt 13 conveying to the left, the plastic cover is conveyed to the packaging machine side. The detection mechanism is arranged on the left side of the support plate 11. The detection mechanism can detect the overall height of the stacked plastic cover. When the detection mechanism detects that the height of the stacked plastic cover meets the requirements, the plastic cover can normally move to the packaging machine side along with the conveying belt 13. When it is detected that the height of the stacked plastic cover does not meet the requirements, the detection mechanism transmits a signal to the control panel, and the control panel controls the conveying belt 13 to stop working. In this way, it can prevent the collapsed plastic cover stack from being conveyed into the packaging machine.

[0026] When it is necessary to convey and package plastic covers of different heights, the worker can drive the two sliding blocks 26 away from each other through the pulling mechanism. When the two sliding blocks 26 are away from each other, the two springs 25 on the two sides start to compress, and drive the two lock pieces 27 away from each other until the lock pieces 27 are received in the through -holes 23. The lock pieces 27 are removed from the lock holes 28. Therefore, the limiting of the vertical rod 2 and the support rod 22 is cancelled. Since the support rod 22 can slide up and down in the chute 21, the design can adjust the up-and-down sliding of the support rod 22 relative to the vertical rod 2. Therefore, the height of the detection mechanism can be adjusted. In this way, the plastic cover stack of different heights can be detected.

[0027] When the support rod 22 is adjusted to the appropriate height, the staff releases the pulling mechanism, cancels the pulling of the two sliders 26, and at this time, the two sliders 26 are pushed to each other under the stretching action of the two springs 25, thereby driving the two locking pieces 27 to simultaneously extend through the through hole 23, at this time, the height of the support rod 22 can be fine adjusted, until the position of the locking piece 27 matches the position of the nearest lock hole 28, and under the stretching action of the spring 25, the locking piece 27 is driven to extend into the lock hole 28, and the support rod 22 is limited.

[0028] The detection mechanism includes two infrared emitters 3 and two infrared receivers 31, the two infrared emitters 3 and the two infrared receivers 31 are oppositely arranged, the two infrared emitters 3 are connected with the lower side of the vertical rod 2 and the upper side of the support rod 22 respectively, and the two infrared receivers 31 are connected with the lower side of the vertical rod 2 and the upper side of the support rod 22 on the other side respectively.

[0029] The infrared emitters 3 and the infrared receivers 31 connected with the two vertical rods 2 cooperate, when the plastic cover stack is located between the lower side infrared emitters 3 and the infrared receivers 31, the infrared signal emitted by the infrared emitter 3 can be blocked, so that it can be judged that the plastic cover stack is located on the left side of the conveying belt 13, and the upper side infrared emitter 3 and the infrared receiver 31 are the same, and can detect the upper end of the plastic cover stack, if the plastic cover stack can block the infrared emitted by the infrared emitter 3, the height of the plastic cover stack is normal, when the plastic cover does not block the infrared of the upper side infrared emitter 3, it can be judged that the plastic cover stack collapses, when the upper side infrared receiver 31 receives the infrared signal, it can transmit the signal to the control panel, and the control panel drives the mechanism to stop working, and drives the conveying belt 13 to stop working.

[0030] The pulling mechanism includes two inner cavities 33 arranged on the upper side of the two support rods 22 respectively, the two inner cavities 33 are provided with connecting holes 34 penetrating through the support rod 22 and connected with the mounting hole 24, the connecting holes 34 are provided with pull wires 35, one end of the pull wire 35 is connected with the slider 26, and rotating rods 36 are rotatably arranged between the two support rods 22, the two ends of the rotating rods 36 extend into the two inner cavities 33 respectively, and the other end of the pull wire 35 is connected with the outer surface of the rotating rod 36.

[0031] When the two sliders 26 need to be pulled, the locking piece 27 is disconnected with the locking hole 28, the staff can rotate the rotating rod 36, the rotating rod 36 can wind the two pull wires 35 in the rotating process, the pull wires 35 drive the sliders 26 to pull, the sliders 26 are driven to enter the mounting hole 24, the spring 25 is compressed, so that the locking piece 27 is driven to enter the through hole 23, when the staff does not rotate the rotating rod 36, the sliders 26 are reset under the stretching action of the spring 25, so that the locking piece 27 is driven to extend out of the through hole 23.

[0032] The middle part of the rotating rod 36 is provided with a handle 37, and the outer surface of the handle 37 is provided with anti-skid lines. The handle 37 is designed to facilitate the staff to rotate the rotating rod 36.

[0033] Both ends of the support plate 11 are provided with two mounting grooves 4, and the two vertical rods 2 are provided with fixed plates 41 close to the side walls of the support plate 11 on the opposite sides, and the fixed plates 41 are provided with fixed holes 42 matched with the mounting grooves 4. The fixed plate 41 is close to the side of the support plate 11, and the staff can pass the screw through the fixed hole 42 to extend into the mounting groove 4, so that the fixed plate 41 can be fixed on the side of the support plate 11.

[0034] The driving mechanism comprises a motor 43 connected with the rack 1, and the motor 43 is in transmission connection with one of the transmission wheels 12. When the motor 43 starts to work, one of the transmission wheels 12 starts to rotate, so that the conveying belt 13 starts to work.

[0035] The conveying belt 13 is detachably connected with the two transmission wheels 12. Such design facilitates the staff to replace and maintain the conveying belt 13.
