Description

Technical Field

[0001] This utility model relates to the field of chain plate conveying technology, specifically a paper roll transport chain plate speed change conveying mechanism. Background Technology

[0002] Chain conveyor is a mechanized conveying equipment that uses metal or engineering plastic plates mounted on a chain as a bearing surface and a motor to drive the chain to transport materials. In the paper roll production process, chain conveyor is used to transport paper rolls from one process to the next.

[0003] In the prior art, Chinese patent application number CN201810787382.5 discloses a precision positioning conveyor line for paper rolls before labeling, including a feeding conveyor chain plate, a positioning conveyor chain plate, and an output conveyor chain plate arranged horizontally from left to right. A first sensor for detecting the passage of the paper roll is installed on the upper surface of the feeding conveyor chain plate, the positioning conveyor chain plate, and the output conveyor chain plate. A second sensor and a third sensor are installed from left to right on the positioning conveyor chain plate to the left of the first sensor. The second sensor is used to detect whether the paper roll passes through the second sensor, and the third sensor is used to detect whether the paper roll passes through the third sensor.

[0004] Based on the above information, it can be seen that the existing technology requires paper roll positioning and the addition of a wrapping machine. Therefore, several new chain plates are added after the original chain plate. The conveying speed of the newly added chain plate can be set to be relatively fast, improving conveying efficiency and preventing paper blockage. However, the old chain plate is limited by the small size of the motor and gearbox, so it cannot be set to a relatively fast conveying speed, otherwise the frequency converter will report a fault. Considering the high cost of replacing all the motors and gearboxes of the original chain plate, the conveying speed of the newly added chain plate can only be the same as that of the original chain plate. This is due to cost control, but the newly added chain plates did not play a speed-up role and failed to effectively improve the conveying speed in the second half of the process. Utility Model Content

[0005] The purpose of this invention is to provide a paper roll transport chain plate speed-changing conveying mechanism to solve the problem of low conveying efficiency mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paper roll transport chain plate speed-changing conveying mechanism, including a support frame installed in a production workshop, a transmission chain and a conveyor chain plate are arranged inside the support frame, the transmission chain and the conveyor chain plate are connected, and a power component connected to the transmission chain is fixedly installed outside the support frame, and the paper roll body to be conveyed is placed on the upper surface of the conveyor chain plate, and a photoelectric sensor for monitoring the conveying status of the paper roll body is fixedly installed on the upper surface of the left end of the support frame.

[0007] Preferably, the upper surface of the conveyor chain plate is configured as an inclined structure, and a rough rubber friction plate is fixedly installed on the outside of the inclined surface of the conveyor chain plate.

[0008] Preferably, the power assembly includes a motor and a speed reducer.

[0009] Preferably, mounting brackets are fixedly installed on the outer surfaces of the front and rear sides of the support frame, and a connecting plate with a bent structure is provided above the mounting brackets.

[0010] Preferably, a limiting rod for limiting and protecting the paper roll body is fixedly installed on the upper end of the connecting plate.

[0011] Preferably, a horizontally arranged guide slide rod is fixedly installed inside the mounting frame, and a compression spring is installed outside the guide slide rod. Furthermore, a limiting plate arranged at equal intervals is fixedly installed at the lower end inside the mounting frame.

[0012] Preferably, the lower end of the connecting plate has a through-hole connecting groove, and the guide slide rod is slidably connected to the connecting groove through the groove, and the lower end of the connecting plate is engaged with the two adjacent limiting plates through the gap.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the paper roll transport chain plate speed change conveying mechanism adopts a novel structural design, the specific details of which are as follows:

[0014] 1. When adding new conveyor chain plates, the motor and gearbox of the original chain plate are used to save costs. Only the program needs to be modified to achieve the speed increase of the newly added chain plate, thereby improving the overall conveying efficiency without increasing the overall deployment cost.

[0015] 2. The upper surface of the conveyor chain plate is set with an inclined structure. The inclined structure can better limit the paper roll body and reduce the rolling of the paper roll body during conveying. In addition, the upper surface of the conveyor chain plate is set with a rough rubber friction plate. The friction plate increases the friction force and can better fix the paper roll body.

[0016] Furthermore, during the conveying of the paper roll body, the limiting rods at the front and rear ends of the support frame are used to limit and protect the paper roll body. The limiting plate is connected to the support frame through the connecting plate.

[0017] Furthermore, after lifting the connecting plate upwards, slide the connecting plate relative to the guide slide rod, thereby sliding the connecting plate and the limiting rod to the appropriate position. Then lower the connecting plate. At this time, the gap between the lower end of the connecting plate and the limiting plate engages with each other to achieve the purpose of fixing. Finally, adjust the distance between the front and rear limiting rods to adapt to different sizes of paper roll bodies. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: Please refer to Figures 1-5In order to achieve the purpose of improving conveying efficiency through speed change, this embodiment provides the following technical solution, which specifically discloses: a support frame 1 installed in the production workshop, a transmission chain 2 and a conveyor chain plate 3 are arranged inside the support frame 1, the transmission chain 2 and the conveyor chain plate 3 are connected, and a power component 4 connected to the transmission chain 2 is fixedly installed on the outside of the support frame 1. The paper roll body 5 to be conveyed is placed on the upper surface of the conveyor chain plate 3. A photoelectric sensor 6 for monitoring the conveying status of the paper roll body 5 is fixedly installed on the upper surface of the left end of the support frame 1. The upper surface of the conveyor chain plate 3 is set as an inclined structure, and a rough rubber friction plate 301 is fixedly installed on the outside of the inclined surface of the conveyor chain plate 3. The power component 4 includes a motor and a reducer.

[0029] When using the device, the power component 4 outside the support frame 1 is turned on, and the power component 4 drives the transmission chain 2 to rotate, thereby causing the transmission chain 2 to drive the conveyor chain plate 3 to move, thereby achieving the purpose of conveying the paper roll body 5. During this process, the inclined structure on the upper surface of the conveyor chain plate 3, in conjunction with the friction plate 301, achieves the purpose of limiting the paper roll body 5.

[0030] To improve the speed of the newly added chain plates in the later sections, thereby increasing overall transport efficiency and preventing paper blockage, Z101 is the original chain plate, while Z102, Z103, Z104, and Z105 are the newly added chain plates. The program for photoelectric sensors 6 (SK1, SK2, SK3, SK4) is modified to achieve the same speed increase achieved by adding chain plates. The original program's variable #Exit (e.g., ...) is called. Figure 4 When the paper roll is at the head of Z102 (e.g.) Figure 6 When the paper roll is ready to be transported to the next conveyor belt, one of the conditions, #Exit_ready (paper roll ready to be delivered), is activated. When there is no paper roll on conveyor belt Z103 and the wrapping machine is operating normally, the second condition, #Exit_enable (exit conveyor belt allows delivery), is activated. When both conditions are activated, the variable #Exit is in the S bit (S bit is 1, R bit is 0). Conveyor belt Z102 executes the paper roll delivery command. Two additional code segments are added to the program (e.g., ...). Figure 5When there is no paper output command on the Z102 chain plate, the paper roll is transported from the Z101 chain plate to the Z102 chain plate. At this time, the speed of the Z102 chain plate should be the same as the speed of the old chain plate Z101. The variable #Exit is in the R position and the variable #Exit is 0. The speed is assigned to the variable "102T1_speed" through the MOVE command 1023. When there is a paper output command on the Z102 chain plate, the paper roll is transported from the Z102 chain plate to the Z103 chain plate. Z102 and Z1 03 are all newly added chain plates, and their speed can be adjusted to be faster. The variable #Exit is in the S position, and the variable #Exit is 1. The speed is assigned to the variable "102T1_speed" via the MOVE command 1415. When the Z102 chain plate moves forward with #T_Fwd or backward with #T_Rev, the speed is assigned to the inverter #Drive_f_setpoint via the MOVE command "102T1_speed". The speed of the chain plates after Z102 is all adjusted to 1415.

[0031] Example 2: Please refer to Figures 6-7 In order to achieve the purpose of limiting and protecting the paper roll body 5, this embodiment provides the following technical solution, which specifically discloses: a mounting frame 7 is fixedly installed on the outer surfaces of the front and rear sides of the support frame 1, and a connecting plate 9 with a bent structure is provided above the mounting frame 7. A limiting rod 8 for limiting and protecting the paper roll body 5 is fixedly installed at the upper end of the connecting plate 9. A guide slide rod 10 arranged horizontally is fixedly installed inside the mounting frame 7, and a compression spring 11 is installed outside the guide slide rod 10. A limiting plate 13 arranged at equal intervals is fixedly installed at the lower end of the mounting frame 7. A connecting groove 12 with a through structure is opened at the lower end of the connecting plate 9, and the guide slide rod 10 and the connecting groove 12 are slidably connected through each other. The lower end of the connecting plate 9 is engaged with the two adjacent limiting plates 13 with a gap.

[0032] During the conveying process of the paper roll body 5, the limiting rods 8 at the front and rear ends of the support frame 1 are used to limit and protect the paper roll body 5. When facing paper roll bodies 5 of different sizes, the limiting rods 8 are first lifted upwards. Then, the connecting plate 9 is slid back and forth by the sliding between the connecting groove 12 and the guide slide rod 10. When the limiting rods 8 move to the appropriate position, the limiting rods 8 are lowered. At this time, the connecting plate 9 moves downwards. Finally, the lower end of the connecting plate 9 is engaged with the gap between the two adjacent limiting plates 13 to achieve the fixing effect of the connecting plate 9.
