Description

Technical Field

[0001] This utility model relates to the field of waste paper recycling technology, and in particular to an automatic spray marking device for waste paper bales on a vehicle. Background Technology

[0002] With the green development of the paper industry, waste paper has become a core recyclable raw material. Currently, paper mills collect 100 to 200 truckloads of waste paper daily. Each truckload of waste paper bales is stacked in the truck bed in a "two-layer, two-row-multiple-column" manner. According to industry quality inspection standards, waste paper bales must undergo sampling inspection before entering the warehouse to control key indicators such as moisture and impurity content. Before sampling, each truckload of waste paper bales to be inspected must be marked with a spray paint to identify the sampling target.

[0003] Currently, the marking process relies on manual operation. Workers need to circle around the truck and randomly mark two layers of stacked waste paper bales. This not only needs to be adapted to the dense stacking scenario of "two rows and multiple columns" to ensure accurate marking, but also needs to complete the marking of a large number of vehicles in a short period of time. This manual marking mode requires people to climb up and mark two layers of waste paper bales, which poses safety risks such as falling and bumping.

[0004] In summary, we propose an automatic marking device for waste paper bales on a vehicle, aiming to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic marking device for waste paper bales on a vehicle. By using this device, the problem of low operational safety in manual marking as described in the background art is solved.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: an automatic spraying device for waste paper bales on a vehicle, comprising multiple spraying components arranged in two parallel rows, with each row maintaining a uniform spacing between the spraying components. Each row of spraying components is connected to a pipe I, one end of each pipe I is connected to a pipe II, the end of each pipe II away from pipe I is connected to a storage tank I, a check valve I is installed on each pipe II, a pressure control pump I is installed between the check valve I and pipe I, and a filter I is installed between the pressure control pump I and the check valve I.

[0007] Preferably, the first pipe includes a parallel section and a vertical section. The two parallel sections are respectively arranged below the two rows of spraying components, and one end of each of the two parallel sections on the same side is connected to a vertical section extending in the same direction. The end of the vertical section away from the parallel section is connected to the second pipe.

[0008] Preferably, the spraying assembly includes a base with an opening at its center. The base is located above the parallel section. A columnar shell is fixedly connected to the top of the base outside the opening. A pipe three is arranged inside the shell along its length. The bottom of the pipe three is connected to the parallel section. Two through holes are opened on the side of the two rows of shells that are close to each other. A pipe four is arranged in the two through holes and is connected to the pipe three. An electric control valve is installed in each of the two pipe fours in the shell. A spray head is installed on the outside of the shell at the end of the pipe four away from the pipe three.

[0009] Preferably, a grooved deceleration belt is fitted onto the outer surface of the vertical portion located between the two rows of the spraying components.

[0010] Preferably, each of the second pipelines is provided with a manual control valve 1 between the first filter and the first check valve, and a manual control valve 2 is provided between the first pressure pump and the first pipeline; one end of each first pipeline connected to the second pipeline is also connected to the fifth pipeline via a tee connector, and the end of the fifth pipeline away from the first pipeline is connected to the first storage tank; each fifth pipeline is provided with a second check valve, a second pressure pump is provided between the second check valve and the first pipeline, a second filter is provided between the second pressure pump and the second check valve, a third manual control valve is provided between the second filter and the second check valve, and a fourth manual control valve is provided between the second pressure pump and the first pipeline.

[0011] Preferably, a storage tank 2 is provided on one side of the two storage tanks 1. The bottom of the inner cavity of the storage tank 2 is connected to a pipe 6. A liquid pump is provided on the pipe 6. The end of the pipe 6 away from the storage tank 2 is connected to two pipes 7 through a tee connector. The ends of the two pipes 7 away from the pipe 6 are respectively connected to the two storage tanks 1. A manual control valve 3 is provided on each of the two pipes 7.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Enhanced operational safety: By using two rows of parallel spraying components with even spacing between each row, combined with the structural design of upper and lower double pipes and double nozzles within the spraying components, and the electric control of the electric valves on each pipe, the truck can be parked between the two rows of spraying components without the need for manual climbing or walking around the truck. The electric valves control the corresponding nozzles to mark the two layers of waste paper, thus avoiding the safety risks of falls and collisions during manual operation.

[0013] Improved marking efficiency and accuracy: Through a dual-path system consisting of a main path (storage tank 1 → pipe 2 → pipe 1 → pipe 3 → pipe 4) and a backup path (storage tank 1 → pipe 5 → pipe 1 → pipe 3 → pipe 4), the main path's pressure pump 1 can quickly establish stable coating pressure, and filter 1 ensures that the coating is free of impurities that clog the nozzles. The backup path can be seamlessly switched during cleaning of filter 1 and maintenance of check valve 1 in the main path, working in conjunction with pressure pump 2 for continuous pressure supply. At the same time, the central control console can precisely control the number and position of the electrically controlled valves as needed. This not only solves the problem of low efficiency in manual marking of more than 100 vehicles per day, but also avoids manual omissions and duplicate markings, ensuring that the sampling targets are clearly identified.

Detailed Implementation

[0016] 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.

[0017] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0018] like Figures 1-5 As shown, an automatic spray marking device for waste paper bales in a vehicle includes multiple spraying components 1 and a central control panel (not shown in the attached figure). The central control panel is electrically connected to various electronic control components in the device. The multiple spraying components 1 are arranged in two parallel rows, and the spraying components 1 in each row maintain a uniform spacing. This arrangement can accurately match the "two-layer, two-row, multi-column" waste paper bale stacking structure in the truck compartment, ensuring that each waste paper bale corresponds to the spraying area. Each row of spraying components 1 is connected to a pipe 2, which is used to collect and transport the coating liquid to each spraying component 1 in the same row. Each pipe 2 has a... Each pipe is connected to a second pipe 3, and the end of each second pipe 3 away from the first pipe 2 is connected to a storage tank 4, forming a basic coating liquid delivery path of storage tank 4 → second pipe 3 → first pipe 2 → spraying assembly 1. Each second pipe 3 is equipped with a check valve 5, which can prevent the coating liquid from flowing back to the storage tank 4 and avoid pressure loss. A pressure control pump 6 is installed between the check valve 5 and the first pipe 2. The pressure control pump 6 can actively draw the coating liquid and adjust the pressure of the passage to ensure that the coating liquid is delivered to the nozzle at a stable pressure. A filter 7 is installed between the pressure control pump 6 and the check valve 5 to filter impurities in the coating liquid.

[0019] Furthermore, the first pipe 2 includes a parallel section 201 and a vertical section 201. The two parallel sections 201 are respectively arranged below the two rows of spraying components 1, and one end of the two parallel sections 201 on the same side is connected to a vertical section 202 extending in the same direction. The end of the vertical section 202 away from the parallel section 201 is connected to the second pipe 3, so that the truck can drive forward after completing the marking, without having to reverse and wait for the next truck to enter between the two rows of spraying components 1, thus increasing the continuity of the spraying.

[0020] Furthermore, the spraying assembly 1 includes a base 101 with an opening at its center. The base 101 is located above the parallel portion 201. A columnar housing 102 is fixedly connected to the top of the base 101 outside the opening. The housing 102 provides protection and support for the internal pipelines, preventing damage from external impacts. Inside the housing 102, a pipe 3 103 is arranged along the length of the housing 102. The bottom of the pipe 3 103 is connected to the parallel portion 201 and is used to receive the coating liquid transported by the pipe 2. Two rows of housings 102 are included. Two through holes are opened on the side that are close to each other. Pipe 104 is installed in the two through holes and is connected to pipe 103. Each of the two pipes 104 has an electric control valve 105 installed in the housing 102. The valve can be remotely controlled to turn on and off through the central control panel to achieve precise control of specific nozzles. The end of pipe 104 away from pipe 103 has a nozzle 106 installed on the outside of the housing 102. The two nozzles can correspond to the two layers of waste paper bags stacked on the truck, and double-layer marking can be completed without manual height adjustment.

[0021] Furthermore, a grooved speed bump is fitted onto the outer surface of the vertical part 202 located between the two rows of spraying components 1. This prevents the wheels of the truck from directly running over the pipe and causing damage. The raised structure of the grooved speed bump can also guide the truck to position itself, helping the driver to quickly park the truck in the middle of the two rows of spraying components 1, ensuring that the waste paper bag and the nozzle position are accurately aligned.

[0022] Furthermore, each pipe 23 is equipped with a manual control valve 8 between filter 7 and check valve 5, and a manual control valve 29 between pressure pump 6 and pipe 2. When maintenance is required on filter 7, check valve 5, or pressure pump 6, closing manual control valves 8 and 29 will cut off the main passage and prevent coating leakage. Simultaneously, one end of each pipe 2 connected to pipe 23 is also connected to pipe 510 via a tee fitting. The end of pipe 510 furthest from pipe 2 is connected to storage tank 4, forming... The backup path runs parallel to the main path. Each pipe 5 10 is equipped with a check valve 2 11. A pressure control pump 2 12 is installed between check valve 2 11 and pipe 1 2. A filter 2 13 is installed between pressure control pump 2 12 and check valve 2 11. A manual control valve 3 14 is installed between filter 2 13 and check valve 2 11. A manual control valve 4 15 is installed between pressure control pump 2 12 and pipe 1 3. When the main path is under maintenance, opening manual control valve 3 14 and manual control valve 4 15 will switch to the backup path, ensuring that the marking work is not interrupted.

[0023] Furthermore, a second storage tank 16 is installed on one side of each of the two storage tanks 1-4. The bottom of the inner cavity of the second storage tank 16 is connected to a sixth pipe 17. A liquid pump 20 is installed on the sixth pipe 17. The end of the sixth pipe 17 away from the second storage tank 16 is connected to two seventh pipes 18 through a tee connector. The ends of the two seventh pipes 18 away from the sixth pipe 17 are respectively connected to the two storage tanks 1-4. Each of the two seventh pipes 18 is equipped with a manual control valve 5 19. When the liquid level in the two storage tanks 1-4 is too low and needs to be replenished, the manual control valve 5 19 on the seventh pipe 18 connected to the corresponding storage tank 1-4 is opened, and the liquid pump 20 connected to the second storage tank 16 is started. The liquid pump 20 transports the liquid in the second storage tank 16 to the first storage tank 4 through the sixth pipe 17 and the seventh pipe 18 until the liquid level in the first storage tank 14 reaches the specified height. Then, the liquid pump 20 and the manual control valve 5 19 are closed to complete the replenishment.

[0024] Working principle: Open manual control valves 18 and 29 on each of pipes 2 and 3, and simultaneously close manual control valves 314 and 415 on pipe 5 and 10, thus establishing the main flow path for the coating liquid: "storage tank 14 → pipe 2 and 3 → pipe 12 → pipe 3103 → pipe 4104 → nozzle 106", ensuring that the coating liquid is delivered to the nozzle 106. Start the pressure control pump 16 on pipe 2 and 3, and the coating liquid in storage tank 14 is drawn into the main flow path. During the process, filter 17 filters impurities in the coating liquid to prevent blockage of the flow path or affect the spraying effect. When the pressure in the flow path reaches the specified pressure of pressure control pump 16, the motor of pressure control pump 16 automatically stops rotating. At the same time, check valve 15 on pipe 2 and 3 prevents the coating liquid from flowing back into storage tank 14, maintaining a stable pressure in the flow path.

[0025] A truck carrying two layers of waste paper bales in two rows and multiple columns is parked between two rows of spray coating components 1, ensuring that the two layers of waste paper bales on the truck correspond to the spray nozzles 106 distributed vertically in the two rows of spray coating components 1. Through the central control console, a specified number of electronically controlled valves 105 can be opened randomly according to the sampling quantity, or the number of electronically controlled valves 105 to be activated can be directly input. After the electronically controlled valves 105 are opened, the pressure coating liquid in the passage passes through the corresponding spray nozzles 106 and is accurately sprayed onto the surface of the target waste paper bales.

[0026] When it is necessary to clean filter 17, or maintain check valve 15 and pressure control pump 16 on pipeline 23, close manual control valve 18 and manual control valve 29 on pipeline 23, open manual control valve 314 and manual control valve 415 on pipeline 510, switch to the backup passage of "storage tank 14 → pipeline 510 → pipeline 12 → pipeline 3103 → pipeline 4104 → nozzle 106", start pressure control pump 212 on pipeline 510 to control the passage pressure, filter 213 simultaneously filters coating liquid impurities, check valve 211 prevents coating liquid backflow, and then control the electric control valve 105 through the central control panel to carry out normal spraying and marking without affecting the spraying and marking work progress.
