Description

Technical Field

[0001] This utility model relates to the field of homogenizer technology, and more specifically to an emergency stop device for a homogenizer. Background Technology

[0002] Homogenizers are mainly used in the fields of tissue dispersion in biotechnology, sample preparation in pharmaceuticals, enzyme treatment in the food industry, detection of pesticide and veterinary drug residues in food, and in the pharmaceutical, cosmetic, paint, and petrochemical industries. They are widely applicable to emulsification, homogenization, and dispersion in industrial production.

[0003] Traditional homogenizers, lacking emergency stop devices, can only operate according to pre-set programs, limiting operational flexibility. When mechanical failures or program errors occur during operation, operators cannot intervene immediately, resulting in the raw materials being processed failing to achieve the desired results, and in severe cases, even wasting materials. Utility Model Content

[0004] In order to solve at least one of the technical problems mentioned in the background art, the purpose of this utility model is to provide an emergency stop device for a homogenizer, which can perform emergency stop processing on the device and effectively avoid subsequent damage caused by abnormal operation of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an emergency stop device for a homogenizer, including a housing for protecting internal components;

[0006] A drive motor is mounted on the housing, and a wheel is fixedly connected to the shaft of the drive motor;

[0007] A transmission wheel is disposed on the outside of the rotating wheel, and a transmission component is disposed on the surface of the transmission wheel. A piston assembly is disposed inside the housing, and the transmission component is used to drive the piston assembly to move.

[0008] An emergency stop assembly is installed between the drive wheel and the rotating wheel. When an emergency stop is required, the transmission connection between the drive wheel and the rotating wheel is cut off.

[0009] The emergency stop assembly includes a transmission wheel sleeved on the outside of the rotating wheel, a drive wheel sleeved on the outside of the transmission wheel, a first through groove on the inner wall of the transmission wheel, a retaining strip adapted to the first through groove fixedly installed on the circumferential side of the rotating wheel, a protrusion fixedly installed on the circumferential side of the transmission wheel, a second through groove for sliding of the protrusion on the inner wall of the drive wheel, and a drive component for driving the transmission wheel to move along its axial direction.

[0010] Furthermore, the driving component includes a first pusher and a second pusher, which are located on both sides of the transmission wheel. When an emergency stop is required, the first pusher pushes the transmission wheel to disengage from the drive wheel. When an emergency stop is not required, the second pusher pushes the transmission wheel to connect with the drive wheel.

[0011] Furthermore, the first pusher includes a slide rod that is slidably mounted on the housing along the axial direction of the transmission wheel. A button is fixedly installed on the side of the slide rod away from the transmission wheel, a disc is fixedly installed on the side of the slide rod near the transmission wheel, a push rod is fixedly installed on the side of the disc near the transmission wheel, and a ball bearing is rotatably mounted on the side of the push rod near the transmission wheel.

[0012] Furthermore, the second pusher is an elastic telescopic rod, one end of which is fixedly installed on the rotating wheel, and the other end of which is fixedly installed on the transmission wheel.

[0013] Furthermore, annular grooves are provided on both sides of the transmission wheel, and multiple rollers are provided in each annular groove. The axial direction of the rollers is parallel to that of the transmission wheel, and a support rod is rotatably provided at the center of the roller shaft. The support rod is fixedly connected to the inner wall of the outer casing.

[0014] Furthermore, the transmission component includes a conveyor belt disposed on the surface of the transmission wheel, and a conveyor wheel disposed on the side of the conveyor belt away from the transmission wheel, the conveyor wheel being connected to the piston assembly.

[0015] Furthermore, the piston assembly includes a piston rod, and a connecting rod is rotatably disposed on the side of the conveyor wheel shaft. The connection point between the connecting rod and the conveyor wheel is not located at the center of the conveyor wheel shaft, and the connecting rod is rotatably connected to the piston rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The rotating wheel mounted on the shaft of the drive motor drives the transmission wheel to rotate through the emergency stop assembly. The transmission wheel drives the piston assembly to move through the transmission component, thereby homogenizing the raw materials inside the homogenizer. The design of the transmission component allows the rotation of the transmission wheel to directly push the piston assembly to perform linear reciprocating motion within the housing. When it is necessary to stop the equipment operation urgently, the drive component drives the transfer wheel to move along its axial direction, causing the transfer wheel to move along the length direction of the clip. At the same time, the protrusion on the transfer wheel will gradually disengage from the second through groove until it is completely disengaged, so that the transfer wheel and the transmission wheel do not contact each other. The rotation of the transfer wheel cannot be transmitted to the transmission wheel, and the transmission wheel stops rotating, thereby achieving the purpose of emergency stop.

[0023] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides an emergency stop device for a homogenizer, characterized in that,

[0025] Includes housing 1, used to protect internal components;

[0026] A drive motor 2 is mounted on the housing 1, and a rotating wheel 3 is fixedly connected to the rotating shaft 21 of the drive motor 2; a transmission wheel 4 is mounted on the outside of the rotating wheel 3, and a transmission component 5 is mounted on the surface of the transmission wheel 4; a piston assembly 6 is mounted inside the housing 1, and the transmission component 5 is used to drive the piston assembly 6 to move.

[0027] The rotating wheel 3 mounted on the rotating shaft 21 of the drive motor 2 drives the transmission wheel 4 to rotate. The transmission wheel 4 drives the piston assembly 6 to move through the transmission component 5, thereby homogenizing the raw materials inside the homogenizer. The design of the transmission component 5 allows the rotation of the transmission wheel 4 to directly drive the piston assembly 6 to perform linear reciprocating motion inside the housing.

[0028] However, traditional homogenizers lack emergency stop devices, meaning they can only operate according to the pre-set program. When mechanical failures or program input errors occur, the device cannot be stopped immediately, resulting in the raw materials being processed inside the device not achieving the expected processing effect and causing waste of raw materials.

[0029] To resolve the above technical issues, please refer to [link / reference]. Figure 3 and Figure 4 An emergency stop assembly 7 is designed on the homogenizer and is located between the drive wheel 4 and the rotor 3. When an emergency stop is required, the transmission connection between the drive wheel 4 and the rotor 3 is cut off.

[0030] The emergency stop assembly 7 includes a transmission wheel 71 sleeved on the outside of the rotating wheel 3, a drive wheel 4 sleeved on the outside of the transmission wheel 71, a first through groove 72 opened on the inner wall of the transmission wheel 71, a retaining strip 73 adapted to the first through groove 72 fixedly installed on the circumferential side of the rotating wheel 3, a protrusion 74 fixedly installed on the circumferential side of the transmission wheel 71, a second through groove 75 for sliding of the protrusion 74 opened on the inner wall of the drive wheel 4, and a drive member 76 for driving the transmission wheel 71 to move along its axial direction.

[0031] The working principle is as follows: When it is necessary to stop the operation of the equipment in an emergency, the drive component 76 drives the transmission wheel 71 to move along its axial direction, so that the transmission wheel 71 moves along the length direction of the clip 73. At the same time, the protrusion 74 on the transmission wheel 71 will gradually disengage from the second through groove 75 until it is completely disengaged. Thus, the transmission wheel 71 and the transmission wheel 4 will not be in contact, and the rotation of the transmission wheel 71 will not be transmitted to the transmission wheel 4. The transmission wheel 4 will stop rotating, thereby achieving the purpose of emergency stop.

[0032] Please see Figure 3 and Figure 4 The driving component 76 includes a first pusher 77 and a second pusher 78, which are located on both sides of the transmission wheel 71. When an emergency stop is required, the first pusher 77 pushes the transmission wheel 71 to disengage from the drive wheel 4. When an emergency stop is not required, the second pusher 78 pushes the transmission wheel 71 to connect with the drive wheel 4.

[0033] Under normal operating conditions, the second pusher 78 continuously pushes the transmission wheel 71 to engage tightly with the drive wheel 4, ensuring effective power transmission and enabling the equipment to operate stably according to the predetermined program. When an emergency stop is required, the first pusher 77 will quickly intervene and use thrust to separate the transmission wheel 71 from the drive wheel 4, thereby interrupting power transmission and achieving a rapid emergency stop, effectively ensuring the safety of the equipment and personnel.

[0034] Please see Figure 3 and Figure 4The first pusher 77 includes a slide rod 771 that is slidably disposed on the housing 1 along the axial direction of the transmission wheel 71. A button 772 is fixedly installed on the side of the slide rod 771 away from the transmission wheel 71. A disc 773 is fixedly installed on the side of the slide rod 771 close to the transmission wheel 71. A push rod 774 is fixedly installed on the side of the disc 773 close to the transmission wheel 71. A ball bearing 775 is rotatably disposed on the side of the push rod 774 close to the transmission wheel 71.

[0035] In an emergency, pressing button 772 on the first pusher 77 moves slide rod 771 along the axis of transmission wheel 71 towards transmission wheel 71, causing ball bearing 775 on push rod 774 to contact transmission wheel 71, thereby pushing transmission wheel 71 and separating transmission wheel 71 from drive wheel 4, thus achieving an emergency stop function. When an emergency stop is not required, the force of the second pusher 78 moves transmission wheel 71 back to its initial position, first making transmission wheel 71 contact drive wheel 4. As transmission wheel 71 rotates, protrusion 74 on transmission wheel 71 aligns with second through groove 75 and slides into second through groove 75, thereby continuing to drive drive wheel 4 to rotate and restoring normal operation of the equipment.

[0036] The second pusher 78 can be an elastic telescopic rod, one end of which is fixedly installed on the rotating wheel 3, and the other end of which is fixedly installed on the transmission wheel 71.

[0037] When an emergency stop is not required, the elastic telescopic rod in the second pusher 78 pushes the transmission wheel 71 to reconnect with the drive wheel 4 when it returns to its original length, so that the machine can resume normal operation.

[0038] Please see Figure 3 and Figure 4 The transmission wheel 4 has annular grooves 8 on both sides of its shaft. Each annular groove 8 contains multiple rollers 9. The rollers 9 are axially parallel to the transmission wheel 4. A support rod 10 is rotatably mounted at the center of the roller 9. The support rod 10 is fixedly connected to the inner wall of the outer casing 1.

[0039] The inner wall of the annular groove 8 is supported by the support rod 10 and the roller 9, so that the transmission wheel 4 will not move while rotating.

[0040] Please see Figure 3 and Figure 5 The transmission component 5 includes a conveyor belt 51 disposed on the surface of the transmission wheel 4, and a conveyor wheel 52 disposed on the side of the conveyor belt 51 away from the transmission wheel 4. The conveyor wheel 52 is connected to the piston assembly 6. The rotation of the transmission wheel 4 is transmitted to the piston assembly 6 for homogenization through the transmission belt and the conveyor wheel 52.

[0041] Please see Figure 3 and Figure 5The piston assembly 6 includes a piston rod 61, and a connecting rod 11 is rotatably mounted on the side of the conveyor wheel 52 shaft. The connection point between the connecting rod 11 and the conveyor wheel 52 is not located at the axis of the conveyor wheel 52, and the connecting rod 11 is rotatably connected to the piston rod 61. Through the rotation of the conveyor wheel 52 and the transmission of the connecting rod 11, the piston rod 61 reciprocates.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
