Description

Technical Field

[0001] This utility model relates to the field of oil press technology, and in particular to a pressing chamber and pressing rod structure for an oil press. Background Technology

[0002] A household oil press is a machine used to extract oil from peanuts, sesame seeds, and other raw materials. The oil extracted is pure, fragrant, and of high quality, making it a green and healthy edible oil. Its compact size makes it ideal for home use, and it has a promising market prospect. The pressing chamber and the pressing rod are the two most crucial components of the oil press. The pressing rod is placed inside the pressing chamber and connected to the drive motor. The pressing chamber is mounted and fixed to the motor housing. The motor drives the pressing rod to rotate within the pressing chamber, pressing the peanuts, sesame seeds, and other raw materials that have entered the chamber.

[0003] Publication (Announcement) No.: CN203697517U discloses a pressing chamber and pressing rod structure for a household oil press, including a pressing chamber, a pressing rod, and an installation mechanism. The pressing rod is placed inside the pressing chamber, and its mounting part is connected to the motor of the oil press. The pressing chamber is connected to the motor housing through the installation mechanism. The installation mechanism includes a connecting wheel and a positioning plate with a mounting hole. The connecting wheel has a cavity that matches the positioning plate and has a limiting step. The positioning plate is placed inside the cavity and connected to the motor housing through the mounting hole. The positioning plate has a through hole for the mounting part of the pressing rod to pass through. The pressing chamber is screwed into the cavity. This type of pressing chamber and pressing rod structure solves the problem of excessive heat generated by the collision and friction between the pressing chamber and the pressing rod due to shaking by preventing relative swaying between them. However, it has a drawback: the pressing chamber and pressing rod generate heat after operation, and if this heat is not dissipated in time, it will limit the working time of the oil press and affect its service life. At the same time, different pressing materials require different operating temperatures. When pressing hard materials such as peppercorns, it is necessary to cool down in time, otherwise the residue will clump together and cannot be discharged quickly. When pressing soft materials such as peanuts, it is necessary to heat up in time, otherwise the residue will not be able to form a shape and will become a paste, which also cannot be discharged quickly. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] Referring to the attached diagram: This oil press's pressing chamber and pressing rod structure includes a pressing chamber 1 and a pressing rod 2 rotating within the pressing chamber 1. The pressing chamber 1 comprises a connecting section 11, a feeding section 12, a liquid outlet section 13, and a slag discharge section 14. The slag discharge section 14 is equipped with a slag cake disc 3, a first temperature regulating component 4, and a second temperature regulating component 6. A slag collection gap 5 is formed between the slag cake disc 3 and the end of the pressing rod 2 to collect the slag, and the collected slag is discharged through a slag discharge channel 31 formed on the slag cake disc 3. The first temperature regulating component 4 is used to guide the temperature regulating medium into and out. The entering temperature regulating medium acts on the slag cake pan 3 to cool or heat the slag cake pan 3. The second temperature regulating component 6 is used to guide the temperature regulating medium into and out. The entering temperature regulating medium acts on the slag discharge section 14 to cool or heat the slag discharge section 14. A third temperature regulating component 7 is provided on the pressing rod 2. The third temperature regulating component 7 is used to guide the temperature regulating medium into and out. The entering temperature regulating medium acts on the pressing rod 2 to cool or heat the pressing rod 2. The principle of this utility model is as follows: the connecting section 11 is used to connect with the shell of the oil press; the feeding section 12 is used to input the material to be processed; the liquid outlet section 13 is used to send the liquid extracted from the material out of the pressing chamber 1; the slag discharge section 14 is used to discharge the processed slag; the slag cake tray 3 plays a guiding role, thereby achieving rapid slag discharge; the first temperature regulating component 4, the second temperature regulating component 6, and the third temperature regulating component 7 play a temperature regulating role. In the initial stage, the temperature is raised or lowered according to the different materials being processed. That is, when pressing hard materials such as pepper, it is necessary to cool down in time, otherwise the slag will clump together and cannot be pressed quickly. Therefore, the first temperature regulating component 4, the second temperature regulating component 6, and the third temperature regulating component 7 are used to introduce a temperature regulating medium that can lower the temperature. When pressing soft materials such as peanuts, it is necessary to raise the temperature in time, otherwise the residue will not be able to form a paste and will not be able to be discharged quickly. Therefore, the first temperature regulating component 4 and the second temperature regulating component 6 are used to introduce a temperature regulating medium that can raise the temperature, so that the temperature of the pressing chamber 1 reaches the temperature required for operation. In the subsequent process, the first temperature regulating component 4 and the second temperature regulating component 6 are used to cool the pressing chamber 1, and the third temperature regulating component 7 is used to cool the pressing rod 2, thereby extending the working time of the oil press.

[0025] The slag cake pan 3 is provided with a first guide structure 32 at the end near the press rod 2 and a second guide structure 33 at the end away from the press rod 2. The first guide structure 32 guides the slag material to move towards the slag discharge channel 31 from multiple directions, and the second guide structure 33 guides the temperature regulating medium to flow along the circumferential direction of the slag cake pan 3. The first guide structure 32 is used to assist in slag discharge and prevent the slag material from clogging in the slag collection gap 5, thereby achieving the effect of rapid slag discharge. The second guide structure 33 is used to extend the flow length of the temperature regulating medium, that is, to extend the service life of the temperature regulating medium and to increase the coverage of the temperature regulating medium, thereby achieving a better cooling or heating effect.

[0026] The first guide structure 32 includes a conical concave surface 321 formed on the slag cake pan 3, and a plurality of first guide grooves 322 formed on the conical concave surface 321 and distributed along the circumferential direction of the slag cake pan 3. The end of the press rod 2 near the slag cake pan 3 has a conical protrusion 21 that matches the configuration of the conical concave surface 321. The first guide grooves 322 are arranged in an arc or straight configuration and communicate with the slag discharge channel 31. The conical concave surface 321 and the conical protrusion 21 have the same function. Both can obtain the slag collection distance 5 by using the same configuration, and can also form a guide by using the inclination formed by the cone. This allows the slag to move quickly towards the slag discharge channel 31 when it is squeezed. The first guide grooves 322 are used to prevent the slag from blocking the slag collection distance 5. The arc configuration of the first guide grooves 322 can adapt to the rotational movement of the press rod. Moreover, the first guide grooves 322 are also interconnected with the slag discharge channel 31, which can further ensure that the slag moves towards the slag discharge channel 31 and achieve a better slag discharge effect.

[0027] The second guiding structure 33 includes a second guiding groove 331 formed on the slag cake pan 3. The second guiding groove 331 has an arc shape extending in the circumferential direction of the slag cake pan 3. The second guiding groove 331 allows the temperature regulating medium to travel around once after entering, thus extending the travel length of the temperature regulating medium, that is, extending the service life of the temperature regulating medium, and also increasing the coverage of the temperature regulating medium, thereby achieving a better cooling or heating effect.

[0028] The first temperature control assembly 4 includes a connecting block 41, a connecting sleeve 42, a first inlet pipe 43, and a first outlet pipe 44. The connecting block 41 is connected to the slag cake disc 3 by bolts and has an inlet hole 411 and an outlet hole 412 that communicate with the second guide groove 331. The connecting sleeve 42 is connected to the connecting block 41 by bolts. Both the first inlet pipe 43 and the first outlet pipe 44 are connected to the connecting sleeve 42, and the position of the first inlet pipe 43 matches the position of the inlet hole 411, and the position of the first outlet pipe 44 matches the position of the outlet hole 412. The first temperature control assembly 4 is externally connected to a medium input mechanism, which delivers... The temperature regulating medium can be gas or liquid. The connecting block 41 is used to block the second guide groove 331. The purpose of the blockage is to ensure that the movement space of the entering temperature regulating medium is limited to the second guide groove 331 and will not flow to other positions. The temperature regulating medium is transported inward by the first inlet pipe 43 and outward by the first outlet pipe 44. The entering medium enters the second guide groove 331 through the inlet hole 411, so that the medium is delivered in place. After flowing around once, it leaves through the outlet hole 412. In this way, the medium can be circulated, which can ensure the temperature regulating effect. The connecting sleeve 42 is also connected to a slag discharge pipe that communicates with the slag discharge channel 31.

[0029] An installation groove 141 is provided at one end of the slag discharge section 14 near the liquid outlet section 13. The installation groove 141 has an arc shape that extends in the circumferential direction of the slag discharge section 14 and is used to install the second temperature regulating component 6. After the slag discharge section 14 and the liquid outlet section 13 are connected, the installation groove 141 forms a closed area, thereby stably installing the second temperature regulating component 6 inside and acting on the pressing chamber 1 to regulate the operating temperature of the pressing chamber 1. In addition, the configuration of the installation groove 141 can also extend the travel length of the temperature regulating medium, that is, extend the service life of the temperature regulating medium and increase the coverage of the temperature regulating medium, thereby achieving a better cooling or heating effect.

[0030] The second temperature control component 6 is configured as a tube body, and is formed by bending to form a second inlet pipe 61, a first guide pipe 62, and a second outlet pipe 63. The first guide pipe 62 is set in the mounting groove 141, and the second inlet pipe 61 and the second outlet pipe 63 are both exposed outside the slag discharge section 14. The second temperature control component 6 is externally connected to a medium input mechanism. The temperature control medium being transported can be gas or liquid. The temperature control medium is transported inward through the second inlet pipe 61, guided by the first guide pipe 62 to travel one circle, and transported outward through the second outlet pipe 63, so that the medium is delivered in place and the medium circulation can be realized, which can ensure the temperature control effect. The first guide pipe 62 is bent to form a configuration that fits the mounting groove 141.

[0031] The third temperature control assembly 7 includes a rotary joint 71, an inlet joint 72, an outlet joint 73, and a second guide tube 74. The rotary joint 71 is located at the end of the press rod 2 away from the cake pan 3. The inlet joint 72 is located at the inlet end of the rotary joint 71, and the outlet joint 73 is located at the outlet end of the rotary joint 71. One end of the second guide tube 74 is located at the inlet end of the rotary joint 71, and the other end extends into the inner cavity formed in the press rod 2. A gap 8 is formed between the inner cavity and the second guide tube 74 through a dimensional difference. The temperature control medium flows through the inlet end of the rotary joint 71 along the second guide tube 74. After entering the inner cavity of the press rod 2 via the provided guide path, the medium enters the outlet end of the rotary joint 71 along the guide path provided by the gap 8. The rotary joint 71 is sealed and inserted into the press chamber 1, and can be simultaneously set with an inlet joint 72 and an outlet joint 73 to realize the circulation of the medium, i.e., one inlet and one outlet, to ensure the temperature regulation effect. The channel for the medium to enter is provided by the second guide tube 74, and the channel for the medium to exit is provided by the gap 8 obtained by the dimensional difference between the second guide tube 74 and the inner cavity of the press rod 2. This can both separate the medium from the used medium and provide a clear guide path.

[0032] The rotary joint 71 has a main channel 711 that communicates with the inlet end of the rotary joint 71 and a diversion channel 712 that communicates with the outlet end of the rotary joint 71. The main channel 711 has a stepped configuration, and its small diameter section is used to insert the second guide tube 74. The large diameter end forms a gap 8 with the second guide tube 74. The gap 8 communicates with the diversion channel 712. The main channel 711 is used to house the second guide tube 74 and also to form the gap 8 with the guide tube 74. The diversion channel 712 is used to discharge the used medium flowing in the gap 8, thereby realizing the circulation of the medium.
