Description

Technical Field

[0001] This utility model relates to the field of curved block processing equipment, and in particular to a demolding and material discharge device. Background Technology

[0002] In baijiu brewing, koji (fermented starter) is a crucial raw material, making koji production a core step in the brewing industry. Traditionally, koji is made by manually pressing it down. However, with increased brewing efficiency, the problems of inconsistent quality, long processing time, and high costs associated with manual koji pressing have become increasingly apparent, and its efficiency can no longer meet the demands of brewing. While mechanized and automated koji production lines are relatively mature, the demolding process after compaction is often overlooked, leading to poor stability and consistency in demolding, sometimes even damaging the koji blocks and affecting subsequent operations. Therefore, developing an efficient demolding and discharging device is one of the important means to improve the quality of koji products. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a demolding and discharging device that drives the discharging mold to move up and down to press out the curved blocks in the curved block mold, with stable operation and meeting the requirements for lubrication and heat dissipation.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a demolding and material discharge device, including a frame, on which a power device for driving a lead screw mechanism is provided. The lead screw mechanism includes a lead screw, which cooperates with a lifting nut of a lifting mechanism. The lifting nut is fixed on a lifting platform. The lifting platform is provided with a lifting guide sleeve for a limiting rod to pass through. The limiting rod is fixed on the frame. Multiple sets of limiting rods and lifting guide sleeves are correspondingly arranged. A through hole is provided on the lifting platform corresponding to the lead screw. A lubrication mechanism is provided on the lifting platform. The lubrication mechanism includes an oil cup set at the bottom of the lifting platform, which is set corresponding to the through hole. An oil inlet hole communicating with the through hole is provided on the lifting platform. The oil inlet hole is connected to a lubrication pipe. The lifting platform is connected to the discharge mold through a connecting device. The bottom of the discharge mold is provided with a groove adapted to the shape of the top of the curved block.

[0005] In a preferred embodiment, the power unit includes a motor, the output end of which is provided with a transmission mechanism, and the output end of the transmission mechanism is connected to a lead screw mechanism.

[0006] In a preferred embodiment, the transmission mechanism is a gearbox.

[0007] In a preferred embodiment, the lead screw mechanism includes a lead screw, a support shaft at the upper end of the lead screw, and a support seat on the frame to support the lead screw mechanism. The support shaft rotates on the support seat via bearings.

Detailed Implementation

[0023] like Figures 1-6 As shown, a demolding and material ejection device includes a frame 1. The frame 1 is equipped with a power unit 2 that drives the rotation of a lead screw mechanism 3. In this embodiment, the power unit 2 includes a motor 201. The motor 201 can be a servo motor with heat dissipation, a stepper motor, or, under lower standards, a conventional motor. The output end of the motor 201 is equipped with a transmission mechanism 202, which is connected to the lead screw mechanism 3. The transmission mechanism 202 can be a reduction gearbox, a gearbox, or a combination of a gearbox and a belt drive mechanism, etc.

[0024] The lead screw mechanism 3 includes a lead screw 301, which cooperates with the lifting nut 401 of the lifting mechanism 4. In this embodiment, the lead screw mechanism 3 includes a lead screw 301, which can be a ball screw structure or a threaded structure. A support shaft 302 is provided at the upper end of the lead screw 301, and a support seat 8 is provided on the frame 1 to support the lead screw mechanism 3. The support shaft 302 rotates on the support seat 8 through bearings, and the lead screw mechanism 3 is rotatably mounted on the support seat 8, which is beneficial to the rotational stability of the lead screw mechanism 3.

[0025] The upper end of the support shaft 302 is provided with a power connector 303. The power connector 303 may be a coupling, a connecting flange, or a gear that meshes with the transmission mechanism 202.

[0026] The lifting nut 401 is fixed on the lifting platform 402. The lifting platform 402 is provided with a lifting guide sleeve 404 through which the limiting rod 403 passes. The limiting rod 403 is fixed on the frame 1. Multiple sets of limiting rods 403 and lifting guide sleeves 404 are provided. In this embodiment, four sets of limiting rods 403 and lifting guide sleeves 404 are provided. The lifting platform 402 is provided with a through hole 405 corresponding to the lead screw 301, through which the lead screw 301 passes. The lifting platform 402 is connected to the discharge mold 7 through the connecting device 6. The bottom of the discharge mold 7 is provided with a groove 701 that matches the shape of the top of the curved block. The connecting device 6 is a rigid connecting part. Generally, two sets of connecting devices 6 are connected to one set of discharge molds 7.

[0027] When the lead screw mechanism 3 rotates, it rotates relative to the lifting nut 401. Due to the cooperation of the limit rod 403 and the lifting guide sleeve 404, the lifting nut 401 and the lifting platform 402 move freely in sync, thereby driving the discharge mold 7 to move up and down. When the discharge mold 7 moves down, it presses out the curved block in the curved block mold.

[0028] Preferably, the lifting platform 402 is provided with a lubrication mechanism 5. The lubrication mechanism 5 includes an oil cup 501 set at the bottom of the lifting platform 402. The height of the oil cup 501 is greater than the lifting stroke of the lifting platform 402. The opening of the oil cup 501 faces upward and is set corresponding to the through hole 405. Part of the lead screw 301 is immersed in the lubricating oil in the oil cup 501. While the lubricating oil rotates and lubricates the lead screw 301, it also carries away the heat generated by the lead screw 301 during rotation relative to the lifting nut 401.

[0029] The lifting platform 402 is provided with an oil inlet 406 that communicates with the through hole 405. The oil inlet 406 is connected to the oil filling pipe 502, and lubricating oil is added to the oil storage cup 501 through the oil inlet pipe 406.

[0030] Furthermore, the bottom of the oil cup 501 is connected to an oil drain pipe 503, and an oil drain valve 504 is provided on the oil drain pipe 503. By setting the oil drain pipe 503 and the oil drain valve 504, it is convenient to perform maintenance to drain the lubricating oil or to replace or circulate the lubricating oil in the oil cup 501, which helps to cool down.

[0031] The lifting platform 402 is equipped with an oil baffle 505 corresponding to the lead screw 301. The oil baffle 505 is fitted on the outside of the lead screw 301 to reduce the splashing of lubricating oil generated during the rotation of the lead screw 301.

[0032] The working principle of this device is as follows:

[0033] During operation, the power unit 2 transmits power to the lead screw mechanism 3 after speed change through the transmission mechanism 202. The lead screw mechanism 3 rotates and drives the lifting platform 402 to perform lifting action. Furthermore, the lifting platform 402 drives the discharge mold 7 to perform lifting action through the connecting device 6, completing the functions of pushing out materials and demolding itself. During production, it can quickly and evenly push the curved blocks out of the mold.

[0034] During operation, the lead screw mechanism 3 generates heat through friction with the lifting nut 401. One section of the lead screw mechanism 3 is immersed in the lubricating oil in the oil cup 501 to meet the needs of lubrication and heat dissipation.

[0035] The groove 701 of the discharge mold 7 is consistent with the shape and height of the curved block, so the two are in uniform and comprehensive contact, which can effectively reduce damage to the curved block during the pressing process and thus improve product quality.

[0036] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The embodiments and features described in this application can be arbitrarily combined without conflict. The protection scope of this utility model should be defined as the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims.
