[0001] This invention relates to a bread pretreatment apparatus and its processing technology, and particularly to a bread pretreatment apparatus and its processing technology. Background Technology

[0002] The bread pretreatment device and its processing technology include a cleaning scraper, a support platform, and a drive assembly. The drive assembly drives the cleaning scraper to clean the dough mixing bucket placed on top of the support platform, removing the dough stuck to the inner wall of the mixing bucket to prepare for the next mixing. However, during the cleaning process, after scraping, dough scraps still remain inside the mixing bucket, making it inconvenient to collect the scraped dough scraps. Summary of the Invention

[0003] Therefore, it is necessary to provide a bread pretreatment device and its processing technology to address the problem that after scraping the inner wall of the dough mixing drum, dough scraps still remain inside the drum, making it inconvenient to collect the scraped dough scraps.

[0004] In a first aspect, the present invention provides a bread pretreatment apparatus, comprising a support body including a shelf and an adjustment rack, wherein a dough mixing bucket is placed on top of the shelf, and further comprising: A limiting component, the limiting component being used to limit the bottom end of the dough mixing bucket to the top surface of the shelf; A movable frame, the first section of which is slidably mounted on the adjusting frame, and the second section of which is rotatably connected to a support shaft, with a first motor fixedly mounted at the top of the support shaft, and the first motor fixedly mounted on the surface of the movable frame; The scraping assembly includes a rotating shaft, an L-shaped scraper fixedly connected to the surface of the rotating shaft, the top end of the rotating shaft being connected to the bottom end of a support shaft via a plug-in assembly, and a collection basket being slidably inserted into the surface of the scraper.

[0006] In one embodiment, the collection basket and the scraper are connected by a connecting assembly, the connecting assembly comprising: The first insertion slot is formed on the surface of the rotating shaft, and a clearance groove is formed at the top of the first insertion slot. The second insertion slot is formed on the scraper; Two plug-in sliders are respectively slidably inserted into the first plug-in slot and the second plug-in slot, and are respectively fixedly connected to both sides of the opening of the collection basket.

[0007] In one embodiment, the plug-in assembly includes: A connecting seat is fixedly connected to the bottom of the support shaft, and a plug-in rail is fixedly connected to the bottom surface of the connecting seat; A plug-in sleeve is slidably connected to the surface of the plug-in rail, and its bottom end is fixedly connected to the top of the rotating shaft. Two gas springs are fixedly connected to the end of the plug-in sleeve. A limiting sleeve is rotatably fitted onto the surface of the connecting seat. The side wall of the limiting sleeve has a clearance opening, and the inner wall of the limiting sleeve contacts the extension and retraction ends of the two gas springs.

[0008] In one embodiment, the surface of the connecting seat is provided with an annular groove, and the top end of the limiting sleeve is fixedly connected to an annular body that slides in cooperation with the annular groove.

[0009] In one embodiment, an arc-shaped rod is fixedly connected to the top of the annular body, a limiting sleeve is fitted on the surface of the arc-shaped rod, the limiting sleeve is fixedly connected to the surface of the connecting seat, and a support spring is fitted on the surface of the arc-shaped rod, with both ends of the support spring fixedly connected to the limiting sleeve and the annular body, respectively.

[0010] In one embodiment, the scraper includes: The first scraping section, and the second insertion slot is formed on the first scraping section; The second scraping section has its first end fixedly connected to the rotating shaft, and its second end integrally formed with the bottom end of the first scraping section. The scraping surfaces of both the second and first scraping sections are arc-shaped, and the arc center angle of the arc-shaped surface is less than 90 degrees.

[0011] In one embodiment, a limit support assembly is provided between the limiting sleeve and the first scraping segment, the limit support assembly comprising: A limiting rail, which is slidably inserted into the inside of the second insertion slot; A hook rod is rotatably connected to the top of the limiting rail, and a hook interface is provided at the end of the hook rod away from the limiting rail; The limiting pin includes a first column and a second column. The second column has a smaller diameter than the first column. The second column is fixedly connected to the surface of the limiting sleeve. The bottom end of the second column is integrally formed with the bottom end of the first column. The hanging interface passes through the first column and is sleeved on the surface of the second column.

[0012] In one embodiment, the limiting component includes: A limiting ring is fixedly connected to the top of the support platform, and the dough mixing bucket is inserted into the inside of the limiting ring; Four overlapping blocks are fixedly connected to the top of the support platform and are arranged in a ring array within the inner space of the limiting ring. Four overlapping grooves are formed at the bottom of the dough mixing bucket, and the four overlapping grooves overlap the four overlapping blocks respectively.

[0013] Secondly, a bread pretreatment process is provided, including the following steps: Step 1: Place the dough mixing bowl on the shelf and use the limiting components to keep it in place; Step 2: The rotating shaft is inserted into the bottom end of the support shaft through the plug-in assembly to install the scraping assembly; Step 3: Move the first motor, support shaft and scraper assembly by moving the frame until the scraper assembly enters the dough mixing drum and the scraper of the scraper assembly sticks to the inner wall of the dough mixing drum. Step 3: Start the first motor. The first motor drives the support shaft to rotate. The support shaft drives the rotating shaft and scraper to move synchronously through the plug-in assembly, realizing scraping and cleaning. The surface residue that overflows the scraper will fall into the collection box, realizing cleaning and collection at the same time.

[0014] The bread pretreatment device and its processing technology described above involve starting the first motor, which drives the support shaft, rotating shaft and scraper to rotate. The scraper scrapes along the inner wall of the dough mixing bucket, and the scraped dough crumbs fall into the collection basket as they pass over the scraper, thus achieving simultaneous scraping and collection.

[0015] With the scraper limiting contact with the inside of the kneading bucket, the limiting component limits the bottom of the kneading bucket, thereby achieving dual limiting of the outside and inside of the kneading bucket. The kneading bucket will maintain stability throughout the scraping process, ensuring the normal progress of scraping and cleaning.

[0016] As the scraper moves into the kneading bowl, it comes into contact with the side wall of the bowl, compressing the gas spring until the bottom and sides of the scraper contact the inner side wall and bottom of the bowl, providing a conforming force. During the connection process, the limiting rail is inserted into the second insertion slot. Then, the connection rod is rotated and the limiting pin is pushed so that the connection interface is aligned with the top of the limiting pin. Then, the bottom end of the limiting rail is pushed against the top of the insertion slider, and the connection interface will be connected to the limiting pin along with the connection rod. Then, the pushing is canceled, and under the reset support of the support spring, the connection interface will be attached to the surface of the first column. The second column will be at the top of the connection plate, limiting the connection rod. This not only limits the insertion slider but also limits the limiting pin, thereby indirectly limiting the position of the limiting sleeve and the collection basket. Attached Figure Description

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0025] The following is combined with Figures 1-11 The bread pretreatment apparatus and its processing technology of the present invention are described.

[0026] like Figures 2 to 8 As shown, in one embodiment, a bread pretreatment device includes a support 1 comprising a shelf 101 and an adjustment rack 102, wherein a dough mixing bucket 2 is placed on top of the shelf 101, and further includes: A limiting component is used to limit the bottom end of the dough mixing bucket 2 to the top surface of the shelf 101; the limiting component includes: The limiting ring 3 is fixedly connected to the top of the shelf 101, and the dough bucket 2 is inserted into the inside of the limiting ring 3. Four overlapping blocks 4 are fixedly connected to the top of the shelf 101 and are arranged in a ring array within the inner space of the limiting ring 3. Four overlapping grooves 5 are provided at the bottom of the dough mixing bucket 2, and the four overlapping grooves 5 overlap with four overlapping blocks 4 respectively. It should be understood that during the process of inserting the dough mixing bucket 2 into the limiting ring 3 and placing the bottom of the dough mixing bucket 2 on the support platform 101, the four overlapping grooves 5 at the bottom of the dough mixing bucket 2 are aligned with the overlapping blocks 4 to form a limit. The dough mixing bucket 2 will be unable to rotate or move laterally on the support platform 101, thus achieving the limit.

[0027] The movable frame 6 has a first section that is slidably mounted on the adjusting frame 102, and a second section that is rotatably connected to a support shaft 7. A first motor 8 is fixedly mounted on the top of the support shaft 7 and is fixedly mounted on the surface of the movable frame 6. The scraping assembly includes a rotating shaft 9, an L-shaped scraper 11 fixedly connected to the surface of the rotating shaft 9, the top end of the rotating shaft 9 being connected to the bottom end of the support shaft 7 via a plug-in assembly, and a collection basket 10 being slidably inserted into the surface of the scraper 11. Specifically, the adjusting frame 102 is provided with a connection port 12, the first section of the movable frame 6 is slidably connected to the connection port 12, the bottom end of the first section of the adjusting frame 102 is fixedly connected to a threaded sleeve 13, the threaded sleeve 13 is internally threadedly connected to a threaded rod 14, the top end of the threaded rod 14 rotates with the top end inside the connection port 12, and the bottom end of the threaded rod 14 is fixedly installed with a second motor 15, which is fixedly installed on the bottom surface inside the connection port 12. It should be understood that before cleaning the dough mixing bucket 2 placed on the shelf 101, the top of the rotating shaft 9 of the scraping component is first inserted into the bottom of the support shaft 7 through the plug-in component. Then, the collection basket 10 is slidably inserted into the surface of the scraper 11. Then, the second motor 15 drives the threaded rod 14 to rotate. The threaded rod 14 will drive the threaded sleeve 13 to move. The threaded sleeve 13 will simultaneously drive the moving frame 6 to move in the connection port 12. The moving frame 6 will simultaneously drive the first motor 8, the support shaft 7, the rotating shaft 9 and the scraper 11 to move until the scraper 11 is attached to the bottom and side wall of the dough mixing bucket 2. Then, the first motor 8 is started. The first motor 8 will drive the support shaft 7, the rotating shaft 9 and the scraper 11 to rotate. The scraper 11 scrapes along the inner wall of the dough mixing bucket 2. When the scraped dough scraps overflow the scraper 11, they will fall into the collection basket 10, realizing scraping and collection at the same time. It should be noted that, under the contact limit of the scraper 11 to the inside of the dough mixing bucket 2, the limiting component limits the bottom of the dough mixing bucket 2, thereby achieving dual limiting of the outside and inside of the dough mixing bucket 2. The dough mixing bucket 2 will maintain stability throughout the scraping process, ensuring the normal progress of scraping and cleaning.

[0028] like Figure 5 , Figure 7 and Figure 8 As shown, in one embodiment, the collection basket 10 and the scraper 11 are connected by a connecting assembly, which includes: The first insertion groove 16 is formed on the surface of the rotating shaft 9, and the top of the first insertion groove 16 is provided with a clearance groove 17. The second insertion slot 18 is formed on the scraper 11; Two plug-in sliders 19 are respectively slidably inserted into the first plug-in groove 16 and the second plug-in groove 18, and are respectively fixedly connected to both sides of the opening of the collection basket 10.

[0029] It should be understood that during the process of connecting the collection frame and the scraper 11, the two plug-in sliders 19 are respectively aligned with the top of the first plug-in groove 16 and the top of the second plug-in groove 18 until the two plug-in sliders 19 slide to the bottom of the inside of the first plug-in groove 16 and the second plug-in groove 18, thus completing the installation of the collection basket 10. The opening of the collection basket 10 faces the upper edge of the scraper 11, so that the surface residue that overflows the scraper 11 falls into the collection basket 10. The collection basket 10 is made of a metal mesh plate, which is breathable and facilitates reducing air resistance when moving. By setting the clearance groove 17, space is provided for the plug-in slider 19 to align with the first plug-in groove 16.

[0030] like Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, in one embodiment, the plug-in assembly includes: Connecting seat 20 is fixedly connected to the bottom of support shaft 7, and a plug-in rail 21 is fixedly connected to the bottom surface of connecting seat 20; The plug sleeve 22 is slidably connected to the surface of the plug rail 21, and its bottom end is fixedly connected to the top of the rotating shaft 9. Two gas springs 23 are fixedly connected to the end of the plug sleeve 22. The limiting sleeve 24 is rotatably sleeved on the surface of the connecting seat 20. The side wall of the limiting sleeve 24 is provided with a clearance opening 25. The inner wall of the limiting sleeve 24 is in contact with the extension and retraction ends of the two gas springs 23.

[0031] The surface of the connecting seat 20 is provided with an annular groove 26, and the top of the limiting sleeve 24 is fixedly connected with an annular body 27 that slides in cooperation with the annular groove 26.

[0032] An arc-shaped rod 28 is fixedly connected to the top of the ring body 27. A limiting sleeve 29 is sleeved on the surface of the arc-shaped rod 28. The limiting sleeve 29 is fixedly connected to the surface of the connecting seat 20. A support spring 30 is sleeved on the surface of the arc-shaped rod 28. The two ends of the support spring 30 are fixedly connected to the limiting sleeve 29 and the ring body 27, respectively.

[0033] It should be understood that during the process of inserting the rotating shaft 9 into the bottom end of the support shaft 7, the limiting sleeve 24 is first rotated so that the clearance port 25 is aligned with the end of the insertion rail 21. Then, the insertion sleeve 22 is inserted into the surface of the insertion rail 21 after passing through the clearance port 25. The gas spring 23 will contact and press against the inner wall of the limiting sleeve 24 under the action of the thrust. The gas spring 23 will be compressed. Then, the limiting sleeve 24 is rotated so that the clearance port 25 avoids the end of the insertion sleeve 22, thereby achieving the limiting and canceling the external force push. The gas spring 23 will push the end of the insertion sleeve 22 against the inner wall of the limiting sleeve 24 under the action of the return spring force. As the scraper 11 moves into the kneading drum 2, the scraper 11 will come into contact with the side wall of the kneading drum 2, and the gas spring 23 will be compressed until the bottom and side of the scraper 11 come into contact with the side wall and bottom surface inside the kneading drum 2, providing the scraper 11 with a bonding force.

[0034] like Figure 5 and Figure 7 As shown, in one embodiment, the scraper 11 includes: The first scraping section 1101 and the second insertion slot 18 are formed on the first scraping section 1101; The second scraping section 1102 has its first end fixedly connected to the rotating shaft 9, and its second end integrally formed with the bottom end of the first scraping section 1101. The scraping surfaces of the second scraping section 1102 and the first scraping section 1101 are both arc-shaped surfaces 1103, and the arc center angle of the arc-shaped surface 1103 is less than 90 degrees.

[0035] It should be understood that by setting the arc-shaped surface 1103, the scraped dough can be guided over the scraper 11 along the arc-shaped surface 1103 and directed to the collection basket 10.

[0036] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 11 As shown, in one embodiment, a limit support assembly is provided between the limit sleeve 24 and the first scraping section 1101. The limit support assembly includes: The limiting rail 31 is slidably inserted into the inside of the second insertion slot 18; The hanging rod 32 is rotatably connected to the top of the limiting rail 31, and the end of the hanging rod 32 away from the limiting rail 31 has a hanging interface 33. The limiting pin 34 includes a first column 3401 and a second column 3402. The thickness of the second column 3402 is smaller than that of the first column 3401. The second column 3402 is fixedly connected to the surface of the limiting sleeve 24. The second column 3402 and the bottom end of the first column 3401 are integrally formed. The hanging interface 33 passes through the first column 3401 and is sleeved on the surface of the second column 3402.

[0037] It should be understood that during the hanging process, the limiting rail 31 is inserted into the second insertion slot 18, and then the hanging rod 32 is rotated and the limiting pin 34 is pushed so that the hanging interface 33 is aligned with the top of the limiting pin 34. Then, the bottom end of the limiting rail 31 is pushed against the top of the insertion slider 19, and the hanging interface 33 will be hung on the limiting pin 34 along with the hanging rod 32. Then, the pushing is canceled, and under the reset support of the support spring 30, the hanging interface 33 will be attached to the surface of the first column 3401, and the second column 3402 will be at the top of the hanging plate, limiting the hanging rod 32. This achieves the limitation of the insertion slider 19 and the limitation of the limiting pin 34, thereby indirectly limiting the position of the limiting sleeve 24 and the collection basket 10.

[0038] like Figure 1 As shown, in one embodiment, a bread pretreatment process includes the following steps: Step 1: Place the dough mixing bucket 2 on the shelf 101 and limit its position using the limiting component; Step 2: The rotating shaft 9 is inserted into the bottom end of the support shaft 7 through the plug-in assembly to realize the installation of the scraping assembly; Step 3: The first motor 8, support shaft 7 and scraping assembly are moved by the moving frame 6 until the scraping assembly enters the dough mixing bucket 2 and the scraper 11 of the scraping assembly sticks to the inner wall of the dough mixing bucket 2. Step 3: Start the first motor 8. The first motor 8 drives the support shaft 7 to rotate. The support shaft 7 drives the rotating shaft 9 and the scraper 11 to move synchronously through the plug-in assembly, so as to achieve scraping cleaning. The surface residue that overflows the scraper 11 will fall into the collection box, so as to achieve cleaning and collection at the same time.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above embodiments are merely illustrative of several implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
