Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary equipment technology, and more specifically, to a support limiting mechanism for a cleaning machine. Furthermore, this utility model also relates to a cleaning machine incorporating the aforementioned support limiting mechanism. Background Technology
[0002] With the rapid development of the pharmaceutical industry, my country's pharmaceutical companies will gradually enter overseas markets. In these overseas markets, the requirements for pharmaceutical equipment cleaning and drying machines will be more stringent. The EU's GMP standards are relatively strict, with more rigorous control over processes requiring minimal or no human intervention. For major domestic biotechnology companies to export their drugs overseas, their drug production practices must strictly adhere to EU GMP standards, controlling processes requiring minimal human contact.
[0003] The cleaning machine support bracket refers to the support for the internal components of the cleaning machine (such as a dish basket). The cleaning machine also includes guide rails. When the cleaning of pharmaceutical equipment is completed or before it is moved, the cleaning machine support bracket is installed by sliding on the guide rails. In order to prevent the cleaning machine support bracket from shifting inside the cleaning machine chamber, a limiting mechanism is required. However, the current limiting mechanism requires manual touch to cancel the limit, which increases the need for manual contact and cannot well meet the production requirements of enterprises.
[0004] In summary, how to provide a limit mechanism that can cancel the limit without manual contact is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a cleaning machine bracket limiting mechanism that can cancel the limit without manual contact, eliminating the risk of traditional limiting devices requiring manual cancellation, reducing the human impact on the container by the operator, and more reliably ensuring the stability of drug production quality.
[0006] Another objective of this invention is to provide a cleaning machine that includes the aforementioned bracket limiting mechanism.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A limiting mechanism for a cleaning machine support includes:
[0009] A bracket for installation inside a cleaning machine, the bracket having a guide rail mounted on it;
[0010] A cleaning rack is slidably mounted on the guide rail, and a limiting rod is provided on the cleaning rack;
[0011] A limiting member is rotatably mounted on the bracket. The limiting member is used to restrict the movement of the cleaning rack along the length direction of the guide rail. When no external force is applied to the limiting member and the cleaning rack moves to a preset position, the limiting member rotates to a position where it engages with the limiting rod to lock the position of the cleaning rack.
[0012] Furthermore, this utility model also includes:
[0013] An insert rod is installed on a transport vehicle. When the insert rod contacts the limiting member, the limiting member rotates to disengage from the limiting rod, thereby removing the restriction on the movement of the cleaning rack.
[0014] Furthermore, the limiting member includes a counterweight and a limiting part, wherein the weight of the counterweight is greater than that of the limiting part.
[0015] Furthermore, in this invention, the limiting member and the rotating part of the bracket are located at the connection between the counterweight and the limiting member.
[0016] Furthermore, the limiting part of this utility model has an L-shaped structure.
[0017] Furthermore, in this utility model, there are two limiting members and two limiting rods, and the two limiting members and two limiting rods are arranged symmetrically.
[0018] Furthermore, in this invention, the maximum rotation angle of the limiting member is less than 10 degrees.
[0019] Furthermore, the bracket is equipped with an elastic element that drives the limiting member to rotate toward the cleaning rack.
[0020] Furthermore, the bottom of the cleaning rack is equipped with rollers that cooperate with the guide rail.
[0021] The cleaning machine support limiting mechanism provided by this utility model allows for the installation of a support within the cleaning machine. A guide rail is mounted on the support, and the cleaning rack is slidably mounted on the guide rail. This means that the cleaning rack can be removed or installed by sliding on the guide rail. The cleaning rack is equipped with a limiting rod, and a limiting member is rotatably mounted on the support. The limiting member restricts the movement of the cleaning rack along the length of the guide rail. When the cleaning rack moves to a preset position on the guide rail, the limiting member rotates under its own weight and contacts the limiting rod, thus fixing the position of the cleaning rack. In other words, when no external force is applied to the limiting member and the cleaning rack moves to the preset position, the limiting member rotates to engage with the limiting rod, locking the position of the cleaning rack and achieving the purpose of fixing its position. This avoids the need for manual contact to activate the limiting device. This structure achieves contactless triggering of the limiting mechanism, reducing human intervention caused by operator contact with the container, and ensuring more stable quality control in pharmaceutical production.

[0030] 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.
[0031] The core of this utility model is to provide a cleaning machine bracket limiting mechanism that can cancel the limit without manual contact. This eliminates the risk of traditional limiting devices requiring manual cancellation, reduces the human impact on the container by the operator, and more reliably ensures the stability of drug production quality.
[0032] Another core aspect of this utility model is to provide a cleaning machine that includes the aforementioned bracket limiting mechanism.
[0033] Please refer to Figures 1-4 ,
[0034] A limiting mechanism for a cleaning machine support includes a support 1, a cleaning frame 3, and a limiting member 6. The support 1 is installed inside the cleaning machine. A guide rail 2 is mounted on the support 1. The cleaning frame 3 is slidably mounted on the guide rail 2. A limiting rod 5 is provided on the cleaning frame 3. The limiting member 6 is rotatably mounted on the support 1. The limiting member 6 restricts the movement of the cleaning frame 3 along the length direction of the guide rail 2. When the cleaning frame 3 moves to a preset position on the guide rail 2, the limiting member 6 rotates under its own weight and contacts the limiting rod 5, thus fixing the position of the cleaning frame 3. When no external force is applied to the limiting member 6, and the cleaning frame 3 has moved to the preset position, the limiting member 6 rotates to engage with the limiting rod 5 to lock the position of the cleaning frame 3.
[0035] It should be noted that in this embodiment of the utility model, the bracket 1 is fixedly installed inside the cleaning machine by means of bolts or welding.
[0036] In addition, in this embodiment of the invention, the length of the limiting rod 5 is not less than twice the width of the limiting member 6, to ensure that the limiting rod 5 and the limiting member 6 are in complete contact.
[0037] In addition, in this embodiment of the present invention, the limiting rod 5 can be installed on the cleaning rack 3 by spot welding.
[0038] In addition, in this embodiment of the present invention, the guide rail 2 is a rod-shaped structure, and the cleaning rack 3 is provided with a groove that cooperates with the guide rail 2.
[0039] In addition, in order to improve the smoothness of the rotation of the limiting member 6 in this embodiment of the utility model, the rotating connection between the limiting member 6 and the bracket 1 is provided with a bearing.
[0040] In use, the bracket 1 is installed inside the washing machine. The bracket 1 is equipped with a guide rail 2, and the washing rack 3 is slidably installed on the guide rail 2. That is, the washing rack 3 can be removed or installed by sliding on the guide rail 2. The washing rack 3 is equipped with a limiting rod 5, and a limiting member 6 is rotatably installed on the bracket 1. The limiting member 6 has the function of restricting the movement of the washing rack 3 along the length direction of the guide rail 2. When the washing rack 3 moves to the preset position on the guide rail 2, the limiting member 6 rotates under its own weight and contacts the limiting rod 5, thereby fixing the position of the washing rack 3. In other words, when no external force is applied to the limiting member 6, and the washing rack 3 moves to the preset position, the limiting member 6 rotates to the position where it engages with the limiting rod 5 to lock the position of the washing rack 3, thus achieving the purpose of fixing the position of the washing rack 3. This avoids the need for manual contact to activate the limiting device, reduces the human impact on the container by the operator, and more stably ensures the stability of the drug production quality.
[0041] Please refer to Figure 1 To further reduce manual intervention, some embodiments also include a plug rod 7, which is installed on a transport vehicle. When the plug rod 7 contacts the limiting member 6, the limiting member 6 rotates to disengage from the limiting rod 5, thereby removing the restriction on the cleaning rack 3. In other words, during use, the transport vehicle is used to transfer the cleaning rack 3. Therefore, the transport vehicle is equipped with a docking guide rail 2. Specifically, the docking guide rail 2 has the same specifications as the guide rail 2 on the bracket 1. Therefore, when the docking guide rail 2 is connected to the guide rail 2 on the bracket 1, the cleaning rack 3 can be pulled out of the cleaning machine and transferred to the transport vehicle, facilitating the transfer of the cleaning rack 3.
[0042] Optionally, in some embodiments, the end of the docking guide rail 2 is provided with a groove. Specifically, after the docking guide rail 2 is inserted into the guide rail 2 on the bracket 1 through the groove, the docking guide rail 2 and the guide rail 2 on the bracket 1 are connected.
[0043] In the above embodiments, in order to improve the smoothness of the guide rail 2 after connection, in some embodiments, the end of the guide rail 2 on the bracket 1 is provided with a protrusion, and the groove is inserted into the protrusion, so as to achieve a fully closed connection between the docking guide rail 2 and the guide rail 2 on the bracket 1.
[0044] Optionally, in some embodiments, the insertion rod 7 has a Z-shaped structure. One end of the Z-shaped insertion rod 7 is fixed to the transport vehicle, and the other end of the insertion rod 7 contacts the limiting member 6 to push the limiting member 6 flat, thereby eliminating the restriction of the limiting member 6 on the limiting rod 5.
[0045] Optionally, in some embodiments, the contact position between the insertion rod 7 and the limiting member 6 is an inclined surface. Specifically, the contact position between the insertion rod 7 and the limiting member 6 is provided with an inclined surface facing away from the insertion rod 7.
[0046] Alternatively, in some embodiments, the insertion rod 7 is fixed to the transport vehicle by welding or bolts, and the welding can be done by spot welding.
[0047] Please refer to Figure 1 In order to enable the limiting member 6 to have an automatic unlocking function, in some embodiments, the limiting member 6 includes a counterweight 61 and a limiting part 62, and the weight of the counterweight 61 is greater than that of the limiting part 62. That is to say, the limiting part 62 is used to fix the position of the limiting rod 5, while the counterweight 61 is used to control the rotation of the limiting member 6 as a whole. Therefore, when the limiting member 6 is not subjected to external force, the counterweight 61 drives the limiting member 6 to rotate as a whole. After the insertion rod 7 contacts the limiting member 6, it pushes the limiting member 6 to rotate. After the insertion rod 7 moves out, the counterweight 61 drives the limiting member 6 to rotate as a whole and makes the limiting part 62 contact the limiting rod 5, thereby realizing the limiting function of the limiting rod 5.
[0048] Alternatively, in some embodiments, the counterweight 61 and the limiting part 62 are supported by an integral molding method.
[0049] Optionally, in some embodiments, the counterweight 61 has an elliptical structure, and the contact position between the counterweight 61 and the insertion rod 7 is provided with an inclined surface, so that the insertion rod 7 can push the counterweight 61.
[0050] Optionally, in some embodiments, the rotatable part of the limiting member 6 and the bracket 1 is located at the connection between the counterweight part 61 and the limiting part 62, and the length and weight of the counterweight part 61 are greater than those of the limiting part 62, which is beneficial for the counterweight part 61 to control the rotation of the limiting member 6 by its own weight.
[0051] Optionally, in some embodiments, the limiting part 62 is an L-shaped structure, which can realize the limiting function of the limiting rod 5.
[0052] In other embodiments, the limiting part 62 may also adopt other shapes that can achieve limiting, such as barb type, V type, etc.
[0053] When the limiting member 6 contacts the limiting rod 5, the limiting member 6 is in an inclined position. Therefore, when the limiting member 6 is in the limiting function position, the limiting rod 5 can be located at the included angle position of the limiting part 62, further improving the limiting effect.
[0054] To further enhance the limiting effect of the limiting rod 5 and prevent the limiting component 6 from detaching from the limiting rod 5 due to shaking of the cleaning rack 3 during the process, the limiting rod 5 is made of iron, and the limiting part 62 of the limiting component 6 is equipped with a magnet. Therefore, when the limiting part 62 of the limiting component 6 comes into contact with the limiting rod 5, it is firmly fixed to the limiting rod 5 by magnetic attraction, preventing accidental detachment and thus avoiding the limiting component 6 from accidentally interfering with the movement of the cleaning rack 3.
[0055] Please refer to Figure 1 In some embodiments, there are two limiting members 6 and two limiting rods 5, and the two limiting members 6 and two limiting rods 5 are arranged symmetrically. That is, the two limiting members 6 simultaneously limit the positions of both sides of the cleaning rack 3, thereby fully fixing the position of the cleaning rack 3 and reducing the slippage of the cleaning rack 3. Specifically, the two limiting members 6 are arranged opposite to the vehicle. Therefore, when the cleaning rack 3 enters the slide rail, the limiting member 6 on the side of the cleaning rack 3 that enters is opened by the insertion rod 7 and is in an unlocked state. The limiting member 6 on the other side is in an inclined state, and the limiting part 62 is located above. When the cleaning rack 3 moves to the other side, the limiting rod 5 on the other side of the cleaning rack 3 contacts the limiting part 62 in the inclined state, thereby limiting the other side of the cleaning rack 3. When it is necessary to remove the cleaning rack 3, it can be removed from either side. The limiting members 6 at the far end will not interfere with the removal of the cleaning rack 3, making it more convenient and faster.
[0056] In the above embodiments, when the limiting part 62 adopts a V-shaped or U-shaped structure, its opening faces the limiting member 6. That is, when the limiting part 62 contacts the limiting rod 5, the limiting rod 5 is located inside the groove of the limiting part 62, thus realizing bidirectional limiting of the limiting rod 5. The cleaning rack 3 is fixed by a limiting member 6, which further reduces the manufacturing cost.
[0057] To further enhance the positioning stability of the cleaning rack 3 and prevent the cleaning rack 3 from shaking inside the cleaning machine, in some embodiments, a torsion spring is provided at the rotation point between the limiting member 6 and the limiting rod 5. This spring is used to drive the limiting member 6 to rotate in the direction of the cleaning rack 3. Therefore, when the limiting member 6 contacts the limiting rod 5, the torsion spring drives the limiting member 6 to push the limiting rod 5, ensuring that the cleaning rack 3 is in a fixed position and preventing the cleaning rack 3 from shaking.
[0058] In other embodiments, the bracket 1 is provided with a fixed protrusion located between two limiting members 6 and at a horizontal height lower than the two limiting members 6. Each of the two limiting members 6 has an elastic member on one side of its counterweight 61, and the other end of the elastic member is connected to the fixed protrusion. Therefore, when the limiting member 6 rotates, the elastic member is stretched. The contraction of the elastic member controls the limiting member 6 to exert a certain thrust on the cleaning rack 3, thereby ensuring that the cleaning rack 3 is in a fixed position and preventing the cleaning rack 3 from shaking. At the same time, when this embodiment is used, the maximum rotation angle of the two limiting members 6 can be fixed to prevent the rotation angle from being too large and causing interference.
[0059] Optionally, in some embodiments, the bracket 1 is provided with a limiting protrusion to limit the maximum rotation angle of the limiting member 6. The maximum rotation angle of the limiting member 6 is less than 70 degrees, so as to prevent motion interference caused by excessive rotation of the limiting member 6.
[0060] The limiting component is rotatably mounted on the bracket. The limiting component restricts the movement of the cleaning rack along the length of the guide rail. When the cleaning rack moves to the preset position on the guide rail, the limiting component rotates under its own weight and contacts the limiting rod, thus fixing the position of the cleaning rack. In other words, when no external force is applied to the limiting component 6 and the cleaning rack 3 moves to the preset position, the limiting component 6 rotates to the position where it engages with the limiting rod 5 to lock the position of the cleaning rack 3, thereby achieving the purpose of fixing the position of the cleaning rack. This avoids the need for manual contact to activate the limiting function of the limiting device, reduces the human impact on the container caused by operator contact, and more reliably ensures the stability of drug production quality.
[0061] In other words, the key point of this utility model embodiment is that: the limiting member 6 is rotatably installed on the bracket 1, and the limiting member 6 has the function of restricting the movement of the cleaning rack 3 along the length direction of the guide rail 2. When the cleaning rack 3 moves to the preset position of the guide rail 2, the limiting member 6 rotates under its own weight and contacts the limiting rod 5, thereby fixing the position of the cleaning rack 3. That is to say, when the cleaning rack 3 slides to the designated position through the guide rail 2, the limiting member 6 rotates under its own weight, causing the limiting member 6 to contact the limiting rod 5, thereby achieving the purpose of fixing the position of the cleaning rack 3. This avoids the need for manual activation of the limiting device, reduces the human influence of the operator on the container, and more stably ensures the stability of the drug production quality.
[0062] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core idea of this utility model.
