Description

Technical Field

[0001] The utility model relates to waste collection, belongs to the technical field of medical treatment, and particularly relates to a turning and unloading device for a medical waste turnover box. Background Art

[0002] Medical waste refers to waste generated during the diagnosis, treatment, and nursing of patients. Because the waste may contain a large number of pathogenic microorganisms and harmful chemicals, the waste needs to be discarded and cannot be reused. To avoid manual contact, medical waste needs to be placed in turnover boxes for transportation;

[0003] Medical waste is transported to a fixed location in turnover boxes for unified collection and transportation. The current collection process still requires manual dumping, meaning workers wearing protective clothing must tilt the turnover boxes to dump the medical waste out. This method is time-consuming and labor-intensive, and can easily cause physical and mental pollution to workers.

[0004] Some use automatic pushing devices, that is, the turnover box is rotatably installed on the conveying trolley. When the conveying trolley is transported to the designated position, the pushing device on one side is started, and the pushing plate acts on the turnover box to flip it over and unload. This method has the following problems: after the turnover box is flipped to a certain angle by the lateral force of the pushing plate, it will break away from the pushing plate and flip freely. At this time, the impact of the turnover box unloading is large, affecting the assembly of the turnover box on the mobile trolley and easily causing damage to the turnover box; in addition, in order to ensure that the turnover box can be flipped back to its original position smoothly, the flipping and unloading angle is limited, and it may not be possible to dump the waste in the turnover box. Summary of the Invention

[0019] In some examples of the present invention, a positioning sensor is provided on the support base;

[0020] The positioning sensor is used to identify the rotation angle of the frame body and transmit the signal to the controller; the controller controls the action of the drive component.

[0021] In some examples of the present invention, the cross section of the guide cover at one end away from the conveying component gradually decreases, and the end close to the conveying component is a rectangular frame;

[0022] The frame body is provided with a support cover of rectangular shell structure;

[0024] In some examples of the present invention, the guide cover is provided with a plurality of positioning plates arranged along the circumferential direction at one end close to the conveying component;

[0025] The positioning plate is an elastic bending structure;

[0026] When the guide cover is arranged on the upper end of the turnover box, the positioning plate can be elastically pressed against the peripheral side of the turnover box.

[0052] like Figure 1 、 Figure 2 、 Figure 3 As shown, the medical waste turnover box overturning and unloading device includes:

[0053] The frame body 30 is an annular structure with a horizontal axis and is driven to rotate and mounted on the support member 20. The frame body 30 is provided with a conveying member 80 for axially moving the turnover box 70.

[0054] The discharge pipe 10 is installed below the support member 20 and is capable of receiving waste after the turnover box 70 is turned over;

[0055] The clamping member 50 is fixedly mounted on the frame body 30 and includes a pair of clamping plates 53 located on both sides of the conveying member 80. The pair of clamping plates 53 are driven to move closer to or away from each other.

[0056] The guide cover 62 is mounted on the frame body 30 so as to be moved up and down by the lifting member 40 and is configured to guide the dumped waste to prevent the waste from overflowing from the turnover box 70 during rotation;

[0057] When the turnover box 70 moves to be positioned on the conveying member 80 , the guide cover 62 moves downward to cover the upper end of the turnover box 70 , and the support member 20 can drive the frame body 30 to rotate at least 180° on a horizontal basis.

[0058] Specifically, the frame body 30 is an integral flip support structure. The annular structure consists of a pair of coaxially arranged rings. Adjacent rings are connected by a frame. The frame is a frame constructed of multiple square steels to connect the rings and support them. The outer dimensions of the frame do not exceed the outer diameter of the rings to prevent the frame body 30 from colliding with other components during rotation. The frame body 30 is provided with a conveying component 80. Preferably, the conveying component 80 is slightly lower than the axis of the frame body 30.

[0059] The support member 20 is configured to support the frame body 30 and drive the frame body 30 to rotate a certain angle;

[0060] The discharge pipe 10 has a rectangular frame structure at the upper end and a cylindrical structure at the lower end. The upper end of the discharge pipe 10 can be connected to the peripheral side of the support member 20 to increase the receiving area when dumping waste;

[0061] A pair of clamping plates 53 in the clamping member 50 are located on both sides of the conveying member 80 and can clamp and fix the peripheral sides of the turnover box 70;

[0062] When the medical waste turnover box flipping and unloading device is initially used, the conveying component 80 in the frame body 30 is arranged horizontally and is capable of receiving the turnover box 70. That is, one side of the conveying component 80 is docked with other conveying components to complete the transfer of the turnover box 70 from the other conveying components to the frame body 30.

[0063] When the turnover box 70 filled with waste is placed on the conveying member 80, the clamping member 50 is activated, that is, the pair of clamping plates 53 move closer to each other to clamp the sides of the turnover box 70. For example, when the turnover box 70 is conveyed horizontally, the clamping plates 53 clamp the turnover box 70 longitudinally in the front and back directions without affecting the conveyance of the turnover box 70.

[0064] When the turnover box 70 is clamped, the guide cover 62 moves downward through the lifting component 40, so that the lower end of the guide cover 62 is located on the upper end of the turnover box 70; the support component 20 drives the frame body 30 to rotate, so that the frame body 30 rotates at least 180 degrees, that is, after the frame body 30 rotates / turns over, it drives the clamped turnover box 70 to turn over. At this time, the guide cover 62 is located at the bottom, and the waste in the turnover box 70 is dumped and transferred from the guide cover 62 to the discharge pipe 10 for collection;

[0065] After the waste in the turnover box 70 is emptied, the support member 20 drives the frame body 30 to rotate in the opposite direction to the initial position, that is, the conveying member 80 is arranged horizontally, and the empty turnover box 70 is transported out of the frame body 30, and waits for the next turnover box 70 filled with waste to enter;

[0066] The medical waste turnover box flipping and unloading device clamps the turnover box 70 on the conveying part 80 through the clamping part 50, the guide cover 62 moves downward and is arranged above the turnover box 70 to prevent leakage of waste, and the support part 20 supports the frame body 30 and drives it to rotate, thereby realizing the flipping and unloading of the medical waste turnover box 70, which not only effectively avoids manual operation and improves the unloading efficiency, but also flips the clamped turnover box 70 by at least 180° to avoid damage to the turnover box 70 and large impact caused by the side push plate; in addition, the guide cover 62 can guide the waste, extend the unloading path of the waste, and avoid the waste being thrown out in an arc trajectory after the turnover box 70 is flipped, causing leakage of the waste, which is inconvenient for collection by the discharge pipe 10.

[0067] In some examples of the present invention, such as Figure 2 、 Figure 3 As shown, the frame body 30 is a coaxially arranged drive ring, a pair of ring bodies, and a frame body connected between the drive ring and the ring bodies;

[0068] The support component 20 includes a support base 21 of a rectangular structure, a plurality of guide wheel assemblies, and a drive assembly;

[0069] A plurality of guide wheel assemblies rotate on the support base 21 and contact the circumference of the ring body;

[0070] The output end of the driving component is connected to the driving ring to drive the rotation;

[0071] Specifically, the guide wheel assembly may include multiple first guide wheels 24 and second guide wheels 25. For example, each ring body is matched with a guide wheel assembly, and each guide wheel assembly includes a pair of first guide wheels 24 and a pair of second guide wheels 25. The size of the first guide wheel 24 is larger than that of the second guide wheel 25; the pair of first guide wheels 24 are located on the outer sides of the ring body and are in tangential contact with the outer peripheral side of the ring body, and the pair of second guide wheels 25 are located between the pair of first guide wheels 24 and are in tangential contact with the inner peripheral side of the ring body, that is, the first guide wheel 24 is used to support the ring body, and the second guide wheel 25 is used to limit the ring body to avoid problems such as misalignment of the frame body 30 during rotation and the inability to accurately control the rotation angle.

[0072] In some examples of the present invention, such as Figure 2 As shown, the drive ring is provided with a gear ring 23;

[0073] The drive assembly includes a first motor 22 and a gear connected to the output end of the first motor 22;

[0074] The gear and the ring gear 23 are meshed and connected with each other;

[0075] Specifically, the first motor 22 can be connected to the controller. After the first motor 22 is started, the gear engages with the ring gear 23 to drive the drive ring to rotate, so as to facilitate the precise control of the rotation angle of the frame body 30, so as to avoid the problem of reduced angle accuracy caused by friction when the frame body 30 rotates.

[0076] In some examples of the present invention, a positioning sensor is provided on the support base 21;

[0077] The positioning sensor is used to identify the rotation angle of the frame body 30 and transmit the signal to the controller; the controller controls the action of the drive assembly;

[0078] Specifically, the positioning sensor can be an angle sensor or a photoelectric sensor. Taking the photoelectric sensor as an example, an identifier matching the photoelectric sensor is provided on the frame body 30. When the frame body 30 rotates to a certain flip angle, the identifier contacts the photoelectric sensor. After receiving the photoelectric signal, the controller controls the action of the drive component. It is explained that this action includes forward rotation, reverse rotation, and start and stop of the frame body 30.

[0079] In some examples of the present invention, Figure 3 、 Figure 4 As shown, the cross section of the guide cover 62 at one end away from the conveying member 80 gradually decreases, and the end close to the conveying member 80 is a rectangular frame;

[0080] The frame body 30 is provided with a support cover 61 of rectangular shell structure;

[0081] During the lifting process of the guide cover 62, the end of the guide cover 62 with a gradually decreasing cross section is always located inside the support cover 61;

[0082] Specifically, initially, when the turnover box 70 is horizontally positioned on the conveying member 80, the cross-section of the upper portion of the guide cover 62 gradually decreases, presenting a constricted structure from bottom to top. The purpose is that when the turnover box 70 is turned over, the constricted structure of the guide cover 62 can collect the waste.

[0083] The support cover 61 is fixedly mounted on the frame body 30. The overall size is larger than the guide cover 62. The vertical height of the support cover 61 is greater than the lifting stroke of the guide cover 62. The purpose is to ensure that one end of the guide cover 62 is always located inside the support cover 61.

[0084] When the frame body 30 rotates 180°, the support cover 61 is aligned slightly above the discharge pipe 10, and the waste is poured out from the turnover box 70, guided and concentrated by the guide cover 62 and falls into the discharge pipe 10. The support cover 61 can limit the falling waste to avoid overflow of the waste. That is, when the guide cover 62 is raised and lowered, the distance between the guide cover 62 and the discharge pipe 10 changes, especially when the frame body 30 rotates 180°. At this time, the guide cover 62 needs to cover one end on the turnover box 70, and the other end is far away from the discharge pipe 10, which can easily cause overflow of the dumped waste. The fixed support cover 61 can dock with the discharge pipe 10 and limit the dumped waste.

[0085] In some examples of the present invention, Figure 4 、 Figure 5 As shown, the guide cover 62 is provided with a plurality of positioning plates 44 arranged along the circumferential direction at one end close to the conveying member 80;

[0086] The positioning plate 44 is an elastic bending structure;

[0087] When the guide cover 62 is placed on the upper end of the turnover box 70, the positioning plate 44 can be elastically pressed against the peripheral side of the turnover box 70;

[0088] Specifically, there are multiple positioning plates 44, which are arranged at intervals around the guide cover 62. The positioning plates 44 can be elastically squeezed on the side of the turnover box 70, so that the guide cover 62 is more tightly covered when it is set on the upper end of the turnover box 70. At the same time, it can also improve the accuracy of the lifting and lowering movement of the guide cover 62, and avoid the guide cover 62 from shaking and being unable to dock with the turnover box 70.

[0089] In some examples of the present invention, Figure 5 As shown, the lifting component 40 includes:

[0090] The first cylinder 41 is movably mounted on the frame body 30, and the telescopic end is connected to the guide cover 62;

[0091] A first guide rod 42, one end of which is connected to the guide cover 62 and the other end of which is connected to the frame body 30 by sliding up and down;

[0092] Specifically, there may be multiple first guide rods 42 , one end of which is connected to the guide cover 62 and the other end of which slides through a sleeve located on the frame body 30 ;

[0093] A first support plate 43 may be fixedly provided on the guide cover 62, and the first support rod 43 is used to connect with the lifting component 40;

[0094] After the first cylinder 41 is started, it drives the guide cover 62 to move up and down. At this time, the first guide rod 42 moves relative to the frame body 30. The first guide rod 42 limits the lifting of the guide cover 62 to avoid swinging or shaking.

[0095] In some examples of the present invention, such as Figure 6 As shown, each clamping plate 53 is connected to the telescopic end of the second cylinder 51 and is connected to the second guide rod 52;

[0096] The second cylinder 51 is fixed to the frame body 30 , and the second guide rod 52 is slidably connected to the frame body 30 .

[0097] Specifically, there may be multiple second guide rods 52 , one end of which is connected to the clamping plate 53 and the other end of which slides through a sleeve located on the frame body 30 ;

[0098] The clamping member 50 is mounted on the frame body 30 via a second support plate 54;

[0099] It is explained that the first cylinder 41 and the second cylinder 51 are both controlled by the controller, that is, the controller controls the sequential start and stop of the first cylinder 41 and the second cylinder 51 to realize the sequential movement of the clamping plate 53 and the support cover 61; it is explained that in order to realize its corresponding actions, it is necessary to set a sensor for detecting the position of the turnover box 70 on the frame body 30. For example, when the photoelectric sensor detects the position of the turnover box 70, the controller receives the signal and controls the conveying component 80 to stop conveying, and then controls the second cylinder 51 to start so that the clamping plate 53 clamps the turnover box 70, and controls the first cylinder 41 to start so that the guide cover 62 docks with the upper end of the turnover box 70.

[0100] In some examples of the present invention, such as Figure 4 As shown, the conveying component 80 includes a pair of conveying components arranged at intervals;

[0101] Each conveying assembly has a plurality of rollers rotating in the same direction and at the same speed, and the conveying direction and speed of a pair of conveying assemblies are the same;

[0102] Specifically, a pair of conveying assemblies move at the same speed and in the same direction to drive the turnover box 70 to move, that is, the front and rear ends of the turnover box 70 are in contact with the conveying assemblies to move;

[0103] The conveying component 80 also includes a second motor 81, a transmission shaft 82, and a pair of transmission assemblies; the output end of the second motor 81 is connected to the transmission shaft 82 to rotate it, and the transmission shaft 82 is rotatably mounted on the frame body 30 through a bearing seat. The transmission assembly may include a first gear fixed to the transmission shaft 82 and a second gear connected to one of the rollers for power transmission. The first gear and the second gear are connected by a transmission chain 83 wound around the outside thereof. When the second motor 81 is started, the same power input is achieved for the pair of conveying assemblies through the transmission shaft 82 and the transmission assembly.

[0104] Multiple rollers are arranged at intervals on the left and right, and adjacent rollers are connected by a transmission belt, and one of the rollers is connected to the transmission assembly, that is, at this time, multiple rollers rotate in the same direction and at the same speed to realize the transportation of the turnover box 70;

[0105] In this example, a pair of conveying components arranged at intervals are set up. Without affecting the conveyance of the turnover box 70, each conveying component limits the end side of the turnover box 70 for conveying, so that the conveying is more stable, and a pair of conveying components leave corresponding space to facilitate other components to act on the turnover box 70.

[0106] The exemplary implementation of the medical waste turnover box flipping and unloading device proposed in the present invention is described in detail above with reference to the preferred embodiments. However, those skilled in the art will understand that, without departing from the concept of the present invention, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present invention can be combined in various ways without exceeding the scope of protection of the present invention, which is determined by the appended claims.
