Technical Field

[0001] This utility model belongs to the technical field of plastic crushing equipment, specifically relating to a medical waste plastic crushing device with a feeding structure. Background Technology

[0002] Medical waste plastics refer to discarded plastic products generated during the medical process. They mainly include disposable medical plastic waste such as medical device packaging, surgical instruments, syringes, infusion bottles (bags), blood transfusion bags, peritoneal dialysis bags, and blood bags. When processing medical waste plastics, operators use crushing devices to crush them to facilitate subsequent processing.

[0003] As described in announcement number "CN220075245U", this plastic crushing device includes a support frame and a feed box fixed to the top of the support frame. Rollers are symmetrically rotatably connected inside the feed box, and fixed cutter handles are symmetrically arranged inside the feed box on both sides of the rollers. A bidirectional crushing mechanism is installed inside the outer casing. This plastic crushing device uses the rotation of the rollers to move waste plastic towards the fixed cutter handles. When the waste plastic reaches the position of the fixed cutter handles, the rollers on the rollers shear the waste plastic into standard small cubes through a shearing action with the cutter heads on the fixed cutter handles. The small cubes fall through the bottom of the feed box into the outer casing, where the crushing mechanism inside the outer casing performs a second crushing. This avoids the waste plastic sticking together after the first crushing, reduces uneven and incomplete crushing, and improves the crushing quality.

[0004] The inventors believe that the above-mentioned plastic crushing device can also be used for crushing medical waste plastics. However, when using the plastic crushing device, since the opening of the feed box is located at the top of the equipment, the opening position is relatively high. At this time, the operator needs to use a shovel to scoop up the medical waste plastics and lift them before putting them into the feed box for crushing. This operation is inconvenient and labor-intensive, thus causing inconvenience to the crushing operation of medical waste plastics.

[0005] Therefore, this utility model provides a medical waste plastic crushing device with a feeding structure to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a medical waste plastic crushing device with a feeding structure, which aims to solve the problem in the prior art that operators need to use a shovel to lift the medical waste plastic into the feeding box for crushing, which is inconvenient to operate.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a medical waste plastic crushing device with a feeding structure, including a support frame, a feeding box connected to the top surface of the support frame, uprights connected to both sides of the feeding box, a movable groove opened on the front end surface of the uprights, a movable block connected to the inner surface at the bottom end of the movable groove, a connecting block connected to the front end surface of the movable block, a feeding hopper connected to the side surface of the connecting block facing the support frame, a discharge port opened on the rear end surface at the bottom end of the feeding hopper, and a guide plate connected to the bottom surface of the feeding hopper.

[0008] In order to enable the movable block to move, as a preferred embodiment of the medical waste plastic crushing device with a feeding structure of this utility model, the inner two ends of the movable groove are connected with bearings, and a screw is connected between the two bearings. One end of the screw extends into the upright and is fixedly connected to the output end of the motor, and the movable block is threaded through one end of the screw.

[0009] In order to block the discharge port, the preferred medical waste plastic crushing device with feeding structure of this utility model has a groove on the rear end surface of the feeding hopper, a baffle connected to the inner surface of the groove, an mounting plate connected to the top surface of the feeding hopper, an electric push rod connected to the top surface of the mounting plate, and the movable end of the electric push rod passing through the mounting plate and connected to the baffle.

[0010] In order to achieve the adaptation of the bottom of the baffle to the guide plate and to guide the medical waste plastic discharged from the feeding hopper, the preferred medical waste plastic crushing device with feeding structure of this utility model has a "T" shaped baffle structure, and the size of the bottom surface of the baffle matches the size of the guide plate. The top surface of the feed box facing the feeding hopper is connected to a guide plate, and the size of the guide plate matches the size of the feeding hopper.

[0011] In order to achieve normal operation control of the motor and electric push rod, the preferred embodiment of the medical waste plastic crushing device with feeding structure of this utility model is that the motor and electric push rod are electrically connected to an external power supply through a control switch.

[0012] In order to facilitate the assembly and disassembly of the feeding hopper, in the preferred embodiment of the medical waste plastic crushing device with feeding structure of this utility model, positioning blocks are connected to both sides of the feeding hopper. The positioning blocks are slidably placed into the positioning groove opened on the top surface of the connecting block. A bolt is connected through one side surface of the connecting block, and one end of the bolt is threaded into the fixing hole opened on one side surface of the positioning block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a feeding hopper that allows operators to deposit medical waste plastic into the lower part of the hopper. The hopper is then raised to a designated position, where an electric push rod moves a baffle upwards, causing the medical waste plastic to slide through a guide plate from the outlet into the feeding box. This completes the feeding operation, eliminating the need for operators to scoop up and lift the medical waste plastic before depositing it into the feeding box, thus facilitating the feeding operation of the crushing device.

[0015] This utility model allows the feeding hopper to be detached from the connecting block through the cooperation of the positioning block, positioning groove, bolt and fixing hole, so that the operator can disassemble and maintain the feeding hopper, thereby ensuring the use effect of the feeding hopper.

[0022] 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.

[0023] Please see Figures 1-4The present invention provides the following technical solution: a medical waste plastic crushing device with a feeding structure, including a support frame 1, a feeding box 2 connected to the top surface of the support frame 1, uprights 3 connected to both sides of the feeding box 2, a movable groove 4 opened on the front end surface of the uprights 3, a movable block 8 connected to the inner side surface at the bottom end of the movable groove 4, a connecting block 9 connected to the front end surface of the movable block 8, a feeding hopper 10 connected to the side surface of the connecting block 9 facing the support frame 1, a discharge port 11 opened on the rear end surface at the bottom end of the feeding hopper 10, and a guide plate 12 connected to the bottom surface of the feeding hopper 10.

[0024] Preferably, bearings 5 ​​are connected to both ends of the inner side of the movable groove 4, and a screw 6 is connected between the two bearings 5. One end of the screw 6 extends into the upright 3 and is fixedly connected to the output end of the motor 7. A movable block 8 is threaded through one end of the screw 6.

[0025] In actual use, when the motor 7 is started, the output end of the motor 7 will drive the screw 6 to rotate in the bearing 5, so that the movable block 8 on the screw 6 will move along the movable groove 4 on the upright 3.

[0026] Preferably, the rear end surface of the feeding hopper 10 is provided with a groove 13, the inner surface of the groove 13 is connected to a baffle 14, the top surface of the feeding hopper 10 is connected to a mounting plate 15, the top surface of the mounting plate 15 is connected to an electric push rod 16, and the movable end of the electric push rod 16 passes through the mounting plate 15 and is connected to the baffle 14.

[0027] In practical use, the electric push rod 16 is activated, allowing the movable end of the electric push rod 16 to drive the baffle 14 to slide within the slide groove 13. After the baffle 14 is moved, it can either block or not block the discharge port 11.

[0028] Preferably, the baffle 14 has a "T" shaped structure, and the size of the bottom surface of the baffle 14 matches the size of the guide plate 12. The top surface of the feed box 2 facing the hopper 10 is connected to a guide plate 17, and the size of the guide plate 17 matches the size of the hopper 10.

[0029] In practical use, the baffle 14 has a "T" shaped structure, and the size of the chute 13 matches the size of the baffle 14. This way, when the baffle 14 slides in the chute 13, the baffle 14 will not shift. The bottom surface of the baffle 14 is in contact with the top surface of the guide plate 12, ensuring that the baffle 14 can completely cover the discharge port 11. When the feeding hopper 10 moves to the top of the upright 3, the top position of the guide plate 17 will be at the bottom position of the discharge port 11, allowing the medical waste plastic that slides out of the discharge port 11 to slide into the feeding box 2 through the guide plate 17.

[0030] Preferably, the motor 7 and the electric push rod 16 are electrically connected to an external power source via a control switch.

[0031] In actual use, the motor 7 and the electric push rod 16 can be controlled by a switch, which is installed on one side of the support frame 1.

[0032] Preferably, the feeding hopper 10 has positioning blocks 18 connected to both sides of its surface. The positioning blocks 18 are slidably placed into the positioning groove 19 opened on the top surface of the connecting block 9. A bolt 20 is connected through one side of the connecting block 9. One end of the bolt 20 is threaded into the fixing hole 21 opened on one side of the positioning block 18.

[0033] In practical use, the positioning blocks 18 on both sides of the feeding hopper 10 are slid into the positioning groove 19, and then the bolts 20 are screwed through the connecting block 9 into the fixing hole 21, so that the feeding hopper 10 and the connecting block 9 can be installed together. When the connecting block 9 moves, it can drive the feeding hopper 10 to move.

[0034] Working principle: When using this medical waste plastic crushing device with a feeding structure, the operator can easily feed the medical waste plastic into the lower feeding hopper 10. After the medical waste plastic in the feeding hopper 10 is fed in, the motor 7 is started, and the output end of the motor 7 drives the screw 6 to rotate in the bearing 5. At this time, the movable block 8 on the screw 6 will move along the movable groove 4 on the upright 3. In this way, the movable block 8 will drive the feeding hopper 10 to move upward through the connecting block 9. When the movable block 8 moves to the top of the movable groove 4, the top of the guide plate 17 on the feed box 2 will be at the bottom of the discharge port 11. At this time, the electric push rod 16 is started, and the movable end of the electric push rod 16 drives the baffle 14 to move in the slide 13. In this way, the baffle 14 will move to the top of the slide 13, and then the discharge port 11 will be opened. The feed inlet 11 will be exposed, so the medical waste plastic inside the feed hopper 10 will slide out from the discharge outlet 11 through the guide plate 12, and then slide into the feed box 2 through the guide plate 17 on the feed box 2 for crushing, thus completing the feeding operation of the feed box 2. Inevitably, when the operator is feeding the feed box 2, he / she needs to scoop up and lift the medical waste plastic to put it into the feed box 2, which brings convenience to the feeding operation of the crushing device. Secondly, when the feed hopper 10 needs to be maintained, cleaned or replaced, simply loosen the bolt 20 to separate one end of the bolt 20 from the fixing hole 21. At this time, the positioning block 18 can slide out from the positioning groove 19, allowing the feed hopper 10 to be separated from the connecting block 9, so that the feed hopper 10 can be disassembled for maintenance, thus ensuring the use effect of the feed hopper 10.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
