Description

Technical Field

[0001] The utility model belongs to the technical field of incense making equipment, in particular to an extrusion device for an incense making machine. Background Art

[0002] As people's material and spiritual living standards continue to improve, incense culture, as a traditional culture, is increasingly valued and respected. Consequently, the demand for incense products is also increasing. However, conventional incense production methods remain at the manual stage, resulting in slow and inefficient production, rough and low-quality incense products. Consequently, numerous machinery manufacturers are developing and producing incense-making equipment.

[0003] Chinese patent publication number CN207803996U discloses an automatic incense stick machine, comprising a frame 1, an incense stick machine body mounted on frame 1, and an incense feeding mechanism mounted at the incense outlet of the incense stick machine body. The incense feeding mechanism comprises a frame 2, an incense feeding conveyor belt mounted at the upper end of frame 2, and a radish feeding conveyor belt mounted at the lower end of the incense feeding conveyor belt. The incense stick machine body comprises a silo for placing raw materials, a hopper connected to the upper end of the silo for receiving the incense stick raw materials, a hydraulic cylinder mounted on one side of the silo, and a detachable forming die mounted on the other side of the silo for extruding the incense sticks. Frame 2 is positioned in the incense outlet direction of the forming die. A cutter frame and a reset mechanism for controlling the reset of the cutter frame are mounted on one side of frame 2. When producing the incense stick, the prepared raw materials are first introduced into the silo through the hopper. The hydraulic cylinder is then activated to squeeze the raw materials in the silo. The extrusion of the raw materials is then completed using the forming die. The formed incense sticks fall from the incense stick machine body onto the incense feeding mechanism. However, since the hopper and silo are connected to the outside world, when the hydraulic cylinder retracts, some air is easily mixed into the raw materials falling into the silo. As the hydraulic cylinder expands, this part of air is mixed with the raw materials and squeezed into shape. The incense sticks formed in this way contain pores, are easy to break, and have poor quality.

[0004] For this reason, a fragrance making machine extrusion device is proposed. Utility Model Content

[0012] Preferably, a vibration motor is fixedly connected to the side of the hopper.

[0013] Compared with the prior art, the present invention has the following advantages and technical effects:

[0014] When making incense, the prepared raw materials are first placed in the hopper, the hydraulic cylinder is started, the hydraulic cylinder retracts, and the electromagnetic reversing valve is started, controlling the cylinder with a sealing plate to open, so that the internal space of the extrusion chamber is connected to the external space through the air pipe, avoiding the generation of negative pressure in the extrusion chamber during the retraction of the hydraulic cylinder. Negative pressure can easily cause air to be sucked into the raw materials, thereby forming cavities in the incense sticks after making, causing the incense sticks to break easily; after the raw materials in the hopper fall into the hopper, the hydraulic cylinder expands, squeezing the raw materials in the hopper into the extrusion chamber. After the extrusion column enters the extrusion chamber, the electromagnetic reversing valve controls the cylinder to close, and the raw materials in the extrusion chamber are gradually squeezed out of the extrusion die to form wet incense sticks.

[0023] When making incense, first put the prepared raw materials into the hopper 5, start the hydraulic cylinder 2, the hydraulic cylinder 2 retracts, and at the same time the electromagnetic reversing valve 9 is started, and the cylinder 10 with the sealing plate is controlled to open, so that the internal space of the extrusion chamber 6 is connected with the external space through the air pipe 8, so as to avoid the generation of negative pressure in the extrusion chamber 6 during the retraction of the hydraulic cylinder 2. The negative pressure can easily cause air to be sucked into the raw materials, thereby forming a cavity in the incense sticks after making incense, causing the incense sticks to break easily; after the raw materials in the hopper 5 fall into the silo 4, the hydraulic cylinder 2 expands, and squeezes the raw materials in the silo 4 into the extrusion chamber 6. After the extrusion column 3 enters the extrusion chamber 6, the electromagnetic reversing valve 9 controls the cylinder to close, and the raw materials in the extrusion chamber 6 are gradually squeezed out from the extrusion die 7 to form wet incense sticks.

[0024] Furthermore, when the cylinder 10 with a sealing plate at the piston end is opened, only the gas in the raw materials in the silo 4 can be allowed to pass through in one direction, thereby preventing the raw materials from being sucked into the air pipe 8; the cylinder 10 is connected to the external air source through the air pipe 8 and the electromagnetic reversing valve 9, and is controlled by the electromagnetic reversing valve 9.

[0025] According to a further optimized solution, the bottom of one end of the extrusion cavity 6 away from the extrusion column 3 is connected to a connecting pipe 11 , and the bottom of the connecting pipe 11 is detachably connected to the extrusion die 7 .

[0033] The sensor 16 is preferably a photoelectric sensor 16 or a capacitive proximity sensor 16, which can measure the presence of raw materials in the hopper 5. After detecting that there is no raw material in the hopper 5, the signal is transmitted to the alarm 17. The alarm 17 recognizes the signal and issues a warning, which can be to light up a light or make a sound.

[0034] To further optimize the solution, a vibration motor 18 is fixedly connected to the side of the hopper 5.

[0035] The vibration motor 18 facilitates the downward movement of the raw materials to prevent them from being retained and adhering to the wall.
