[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Reference Figure 2 , Figure 3 and Figure 6 The utility model provides an embodiment: a CTP plate-making machine receiving device, comprising an equipment frame 1 and a receiving vehicle 13, a working machine 3 is fixedly connected to the right side of the top of the equipment frame 1, a receiving chamber 4 is fixedly connected to the right end of the bottom wall of the equipment frame 1, track grooves 5 are provided on the front and rear sides of the inner bottom wall of the receiving chamber 4, tension springs 6 are fixedly installed at the bottom ends of the inner walls of the two track grooves 5, limiting grooves 7 are provided on the left sides of the inner bottom walls of the two track grooves 5, and the tops of the two tension springs 6 are fixedly connected to ramp columns 8 The middle of the outer walls of the two slope columns 8 are fixedly connected to the limit plate 9, the left side of the inner wall of the material receiving chamber 4 is fixedly connected to the sensor 10, the middle of the inner bottom wall of the material receiving chamber 4 is fixedly installed with multiple telescopic rods 11, the output ends of the multiple telescopic rods 11 are fixedly connected to the pressure plate 12, the four corners of the bottom wall of the material receiving vehicle 13 are fixedly connected with universal wheels 14, the bottom ends of the multiple universal wheels 14 are slidably connected to the inner bottom walls of the two track grooves 5, and the middle of the bottom wall of the equipment frame 1 is provided with a printing plate storage device 2;

[0041] Specifically, the universal wheel 14 at the bottom of the material receiving trolley 13 slides in the track groove 5 to facilitate the collection and movement of the material receiving trolley 13. After the universal wheel 14 on the left side presses over the ramp column 8 in the track groove 5, the tension spring 6 on the inner wall of the ramp column 8 will push the ramp column 8 back to the highest height according to the position of the limit plate 9. Since the top surface of the ramp column 8 is designed as a slope, it is relatively easy for the material receiving trolley 13 to enter the track groove 5, but it needs to overcome a certain resistance to come out, so as to fix the material receiving trolley 13 when receiving the materials. After the material receiving trolley 13 enters the track groove 5, the left side of the material receiving trolley 13 will touch the sensor 10, and at the same time, it will send signals to the working machine 3 and the telescopic rod 11, so that the working machine 3 will transfer the printing plate to the material receiving trolley 13, and the telescopic rod 11 will push the pressure plate 12 upward to measure the weight of the material receiving trolley 13.

[0042] Reference Figure 1 , Figure 4 and Figure 5 The printing plate storage device 2 includes a printing plate storage rack 201, a plurality of vacuum chambers 202 are provided on the front side of the printing plate storage rack 201, side strips 203 are fixedly connected to the left and right sides of the inner walls of the plurality of vacuum chambers 202, storage boxes 204 are provided on the adjacent sides of the plurality of side strips 203, negative pressure plates 205 are fixedly connected to the front ends of the plurality of storage boxes 204, rubber rings 206 are fixedly connected to the rear sides of the plurality of negative pressure plates 205, a vacuum machine 207 is fixedly connected to the left side of the bottom wall of the equipment rack 1, a conduit 208 is connected to the output end of the vacuum machine 207, an input end of the conduit 208 is connected to the left side of the printing plate storage rack 201, and a guide groove 209 is provided on the top of the inner wall of the printing plate storage rack 201;

[0043] Specifically, when the printing plate is placed in the storage box 204, the vacuum machine 207 starts to work, and the air in the vacuum chamber 202 is extracted through the conduit 208 to form a negative pressure environment. At the same time, the rubber ring 206 enhances the sealing between the negative pressure plate 205 and the vacuum chamber 202. Due to the negative pressure formed in the vacuum chamber 202, the air between the storage box 204 and the printing plate and between the storage box 204 and the vacuum chamber 202 is extracted, so that the printing plate is tightly attached to the storage box 204 and the negative pressure plate 205.

[0044] Reference Figure 2 A control console 15 is fixedly connected to the front side of the equipment rack 1, and a plurality of control buttons 16 are fixedly installed on the top wall of the control console 15; a working indicator light 17 is fixedly connected to the middle of the top wall of the working machine 3, and a buzzer 18 is fixedly connected to the right side of the working indicator light 17;

[0045] Specifically, the control buttons 16 on the console 15 are used to execute specific commands or functions, such as start, stop, reset, etc. The working indicator light 17 uses different colors or flashing modes to indicate different states, such as green for normal operation and red for fault or stop state. The buzzer 18 is used to send out sound signals to alert the operator to the status or events of the equipment.

[0046] Reference Figure 2 and Figure 3 , the four corners of the bottom wall of the equipment frame 1 are fixedly connected with columns 19, and the bottom ends of multiple columns 19 are fixedly connected with anti-slip pads 20; the front and rear sides of the inner wall of the equipment frame 1 are rotatably connected with multiple pulleys 21, and the right side of the working machine 3 is fixedly connected with a discharge hopper 22; the front sides of multiple negative pressure plates 205 are fixedly connected with handles 23; the right end of the inner bottom wall of the receiving chamber 4 is designed with a slope;

[0047] Specifically, the column 19 and the anti-slip pad 20 can effectively increase the friction between the entire material collecting device and the ground, prevent it from sliding or shifting during operation, and ensure the stability and safety of the work. The pulley 21 can make the material collecting device easier to move and adjust its position during operation, thereby improving work efficiency. The discharge hopper 22 can smoothly export the processed printing plates to the appropriate position for subsequent collection and processing. The handle 23 on the front side of the negative pressure plate 205 is designed to facilitate the staff to easily move or adjust the position of the negative pressure plate 205 during operation and maintenance, thereby improving the convenience of operation. The slope design on the right end of the bottom wall of the material collecting chamber 4 facilitates the entry and exit of the material collecting vehicle 13, thereby facilitating the centralized collection and processing of materials and improving work efficiency.

[0048] The receiving trolley 13 is a carrier for storing and transporting printing plates, and the universal wheel 14 at the bottom slides in the track groove 5 to facilitate the collection and movement of the receiving trolley 13. After the universal wheel 14 on the left side presses over the ramp column 8 in the track groove 5, the tension spring 6 on the inner wall of the ramp column 8 will push the ramp column 8 back to the highest height according to the position of the limit plate 9. Since the top surface of the ramp column 8 is a slope design, it is easier for the receiving trolley 13 to enter the track groove 5, but it needs to overcome a certain resistance to come out, so as to fix the receiving trolley 13 when receiving materials. After the receiving trolley 13 enters the track groove 5, the left side of the receiving trolley 13 will touch the sensor 10, and at the same time, it will send signals to the working machine 3 and the telescopic rod 11, so that the working machine 3 will transfer the printing plate to the receiving trolley 13, and the telescopic rod 11 will push the pressure plate 12 upward to measure the weight of the receiving trolley 13. When the weight of 13 reaches a preset value, the working indicator light 17 and the buzzer 18 will be triggered to remind the operator to replace the new material receiving car 13 in time for receiving, which saves a lot of time for personnel to watch the equipment and reduces the amount of manual reuse. When the printing plate is placed in the storage box 204, the vacuum machine 207 starts to work and extracts the air in the vacuum chamber 202 through the conduit 208 to form a negative pressure environment. At the same time, the rubber ring 206 enhances the sealing between the negative pressure plate 205 and the vacuum chamber 202 to prevent air leakage. Due to the negative pressure formed in the vacuum chamber 202, the air between the storage box 204 and the printing plate and between the storage box 204 and the vacuum chamber 202 is extracted, so that the printing plate is tightly attached to the storage box 204 and the negative pressure plate 205, thereby reducing the contact between the printing plate and oxygen in a vacuum environment, effectively slowing down the oxidation rate of the printing plate, and helping to maintain the cleanliness and quality of the surface of the printing plate.
