Description

Technical Field

[0001] This application relates to the field of yeast production equipment, and in particular to a positioning component for a yeast tray rack. Background Technology

[0002] In the production, storage, and transportation of yeast, yeast tray racks are key equipment for supporting the yeast, and their stability and positioning accuracy directly affect the storage quality and operational efficiency. Currently, traditional yeast tray racks mostly rely on manual visual alignment or simple limiting structures for positioning, lacking specialized precision positioning components.

[0003] This positioning method has many problems: On the one hand, due to the lack of effective positioning and coordination between the pallet rack legs and the placement surface, it is very easy to shift, tilt or even tip over when subjected to external force collision or vibration, which may not only cause the yeast to scatter and be damaged, but also pose a safety hazard; on the other hand, manual positioning is inefficient and it is difficult to ensure the neat arrangement between multiple pallet racks, which is not conducive to the rational use of warehouse space and standardized management.

[0004] While some existing technologies incorporate positioning holes or protrusions, the fit between these holes and the pallet rack legs is often poor. Excessive gaps prevent stable positioning, while insufficient gaps lead to installation difficulties. Furthermore, most existing positioning structures are fixed and cannot be adjusted for different pallet rack leg sizes, resulting in poor versatility and difficulty in meeting diverse production needs. Additionally, the lack of effective guiding structures during pallet rack placement hinders the legs from quickly and accurately entering their positioning positions, further reducing operational efficiency.

[0005] Therefore, developing a positioning component for yeast tray racks that can achieve precise positioning, stability, reliability, versatility, and easy and quick installation is key to solving the positioning problem in the current yeast storage and operation process, and is of great significance for improving the level of yeast production management. Utility Model Content

[0006] In order to overcome the problems existing in the prior art, this application provides a positioning component for a yeast tray holder.

[0007] The positioning component of the yeast tray rack provided in this application adopts the following technical solution:

[0008] A positioning assembly for a yeast tray rack includes a base plate and a positioning mechanism disposed on the base plate. The base plate is fixedly installed on the ground and has several positioning holes for positioning with tray legs. The positioning mechanism includes positioning plates arranged in a ring on three sides of the positioning holes, comprising a first plate, a second plate, and a third plate. The first and second plates are intersecting, with the first and second plates forming right angles with the junction of the base plate. An inclined guide plate is also provided at the end of the first plate near the edge of the base plate. The third plate is slidably mounted on the second plate, and a power mechanism for driving its movement is provided at the end of the third plate away from the first plate. The junctions of the second and third plates form right angles with the bottom surface.

[0009] By adopting the above technical solution, during the placement of the yeast tray rack, the base plate fixed to the ground provides a foundation for positioning, and the positioning holes on it are used to cooperate with the tray legs. When the tray rack legs approach the positioning mechanism, the inclined guide plate at the end of the first plate acts as a guide, causing the legs to move towards the positioning holes along the guide direction. Since the first and second plates are intersecting and form right angles with the base plate respectively, they constitute a preliminary positioning space, providing lateral restraint for the legs. At the same time, the power mechanism can drive the third plate, which is slidably mounted on the second plate, to move. The third plate also forms a right angle with the base plate and cooperates with the first and second plates. By adjusting the position of the third plate, it can adapt to different sizes of legs, achieving precise clamping and positioning of the legs. Finally, the legs are stably embedded in the positioning holes, completing the rapid, accurate, and stable positioning and installation of the tray rack. Positioning multiple tray racks in this way can ensure neat arrangement, improving work efficiency and space utilization.

[0010] Preferably, the power mechanism includes a base and an adjusting rod passing through the base, wherein one end of the adjusting rod is rotatably connected to the third plate; wherein the adjusting rod is arranged along the sliding direction of the third plate, and the adjusting rod includes a sliding shaft portion rotatably connected to the third plate and a screw portion that engages with the internal thread of the base.

[0011] Preferably, an adjusting gear is fitted at one end of the adjusting rod located on the screw section. The adjusting gear is fitted to one end of the base and threadedly connected to the screw section. The end of the adjusting gear away from the base is fitted to the L-shaped limiting plate. The L-shaped limiting plate is connected to the side of the base, and an internal threaded through hole adapted to the screw section is provided on the L-shaped limiting plate.

[0012] Preferably, the adjusting gear is driven by a manual gear, which is located between the adjusting gears and engages with them for transmission; wherein, the manual gear is rotatably mounted on a mounting plate between the bases, and a handle is provided on the outer surface of the manual gear near the edge of the gear.

[0013] Preferably, a locking screw passes through the handle, and the locking screw passes through the manual gear and is adapted to the locking hole on the mounting plate; wherein the locking hole on the mounting plate is arranged in a circumferential array along the manual gear.

[0014] Preferably, the power mechanism is provided with a cover on the outside, wherein the cover has a through hole for the extension and retraction of the adjustment rod and an operating hole for the rotation of the manual gear.

[0015] By adopting the above technical solution, when it is necessary to adjust the position of the third plate to adapt to different specifications of the support legs, the power mechanism is operated as follows: First, loosen the locking screw so that it disengages from the locking hole on the mounting plate. Then, turn the handle on the manual gear. The manual gear rotates and drives the adjusting gear that meshes with it to rotate. The adjusting gear rotates under the limit of the L-shaped limiting plate and the base, thereby driving the screw part of the adjusting rod that is threaded to it to rotate. Since the screw part is threaded with the base and the adjusting rod is arranged along the sliding direction of the third plate, when the screw part rotates, it will drive the sliding shaft part and the third plate that is rotatably connected to it to slide along the second plate. After the third plate is adjusted to the appropriate position, the locking screw is passed through the handle and the manual gear and screwed into the locking hole at the corresponding position on the mounting plate to fix the manual gear. At this time, the position of the adjusting rod is fixed and the position of the third plate is locked. The cover on the outside of the power mechanism provides space for the extension and retraction of the adjusting rod and the operation of the manual gear through the through hole and the operating hole, while protecting the internal structure and completing the precise adjustment of the third plate to ensure the stable clamping of the support legs by the positioning component.

[0016] Preferably, the first plate, the second plate, and the third plate are all inclined upwards toward the center, with the positioning holes located on both sides of the second plate.

[0017] Preferably, the positioning hole is adapted to the positioning protrusion at the bottom of the yeast tray support leg, wherein the inner diameter of the positioning hole is larger than the positioning protrusion.

[0018] By adopting the above technical solution, when the legs of the yeast tray rack approach the positioning mechanism, the first, second, and third plates, tilted upwards towards the center, will guide the legs towards the center, leading them to move towards the positioning holes located on both sides of the second plate. As the legs gradually approach the positioning position, the positioning protrusions at the bottom of the legs also approach the positioning holes. Since the inner diameter of the positioning holes is larger than the positioning protrusions, sufficient leeway is provided for the positioning protrusions to be inserted, facilitating quick alignment and insertion. At the same time, the three tilted plates form a surrounding limit on the legs from different directions, which, in conjunction with the matching of the positioning holes and the positioning protrusions at the bottom of the legs, can firmly fix the legs, effectively preventing the legs from shifting due to external forces, and ensuring the stability and accuracy of the yeast tray rack positioning.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. This application uses the positioning holes on the base plate to cooperate with the pallet support feet, and combines the positioning plates distributed in a three-sided ring to form a stable limiting structure. The first plate and the second plate intersect to form a right-angle positioning, and the inclined guide plate can guide the support feet to quickly enter the positioning position, thereby improving installation efficiency.

[0021] 2. The third plate in this application achieves sliding adjustment through a power mechanism, which can adapt to different specifications of pallet frame support leg sizes, enhancing versatility. In addition, the screw part of the adjusting rod in the power mechanism is threaded with the base, and with the help of the adjusting gear and manual gear drive, the position of the third plate can be precisely controlled to ensure reasonable positioning gap. This avoids displacement and tilting caused by excessive gap, and also prevents installation difficulties caused by insufficient gap.

[0022] 3. The positioning plate in this application is tilted upwards towards the center, which further improves the positioning stability, effectively prevents the pallet rack from shifting or tipping due to external collisions or vibrations, reduces the risk of yeast spillage and damage and safety hazards, helps multiple pallet racks to be arranged neatly, improves warehouse space utilization and standardized management level, and has significant significance for improving the level of yeast production management.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a positioning component for a yeast tray holder.

[0031] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A positioning assembly for a yeast tray rack includes a base plate 1 and a positioning mechanism 2 disposed on the base plate 1. The base plate 1 is fixedly installed on the ground and has a plurality of positioning holes 11 for positioning with tray legs. The positioning mechanism 2 includes positioning plates 3 arranged in a ring on three sides of the positioning holes 11, including a first plate 31, a second plate 32 and a third plate 33. The first plate 31 and the second plate 32 are intersecting, wherein the first plate 31 and the second plate 32 form right angles with the junction of the base plate 1, and the first plate 31 near the edge of the base plate 1 is also provided with an inclined guide plate 311. The third plate 33 is slidably mounted on the second plate 32, and the third plate 33 away from the first plate 31 is provided with a power mechanism 4 for driving its movement, and the second plate 32 and the third plate 33 form right angles with the junction of the bottom surface. During the placement of the yeast tray rack, the base plate 1, fixed to the ground, provides the foundation for positioning, and its positioning holes 11 are used to cooperate with the tray legs. When the tray rack legs approach the positioning mechanism 2, the inclined guide plate 311 at the end of the first plate 31 guides the legs to move towards the positioning holes 11 along the guide direction. Since the first plate 31 and the second plate 32 are intersecting and form right angles with the base plate 1 respectively, they constitute a preliminary positioning space, which limits the legs on both sides. At the same time, the power mechanism 4 can drive the third plate 33, which is slidably mounted on the second plate 32, to move. The third plate 33 also forms a right angle with the base plate 1. It cooperates with the first plate 31 and the second plate 32. By adjusting the position of the third plate 33, it can adapt to the size of different specifications of the legs, achieve precise clamping and positioning of the legs, and finally make the legs stably embedded in the positioning holes 11, completing the rapid, accurate and stable positioning and installation of the tray rack. Multiple tray racks can be positioned in this way to ensure neat arrangement, improve work efficiency and space utilization.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The power mechanism 4 includes a base 41 and an adjusting rod 42 passing through the base 41, wherein one end of the adjusting rod 42 is rotatably connected to the third plate 33; wherein the adjusting rod 42 is arranged along the sliding direction of the third plate 33, and the adjusting rod 42 includes a sliding shaft portion 421 rotatably connected to the third plate 33 and a screw portion 422 that is threadedly engaged with the base 41. An adjusting gear 423 is fitted at one end of the adjusting rod 42 located at the screw portion 422, the adjusting gear 423 is in contact with one end of the base 41 and threadedly connected to the screw portion 422, and the end of the adjusting gear 423 away from the base 41 is in contact with an L-shaped limiting plate 424; wherein the L-shaped limiting plate 424 is connected to the side of the base 41, and the L-shaped limiting plate 424 has an internally threaded through hole adapted to the screw portion 422. The adjusting gear 423 is driven by the manual gear 43, which is located between the adjusting gears 423 and engages with them for transmission. The manual gear 43 is rotatably mounted on the mounting plate 411 between the bases 41, and a handle 431 is provided on the outer surface of the manual gear 43 near the edge of the gear. A locking screw 432 passes through the handle 431 and is adapted to the locking hole 412 on the mounting plate 411. The locking holes 412 on the mounting plate 411 are arranged in a circumferential array along the manual gear 43. A cover 5 is provided on the outside of the power mechanism 4, and the cover 5 has a through hole 51 for the extension and retraction of the adjusting rod 42 and an operating hole 52 for the rotation of the manual gear 43. When the position of the third plate 33 needs to be adjusted to accommodate different sizes of support legs, operate the power mechanism 4: first, loosen the locking screw 432 to disengage it from the locking hole 412 on the mounting plate 411, then turn the handle 431 on the manual gear 43. The manual gear 43 rotates and drives the adjusting gear 423, which meshes with it, to rotate. The adjusting gear 423 rotates under the limitation of the L-shaped limiting plate 424 and the base 41, thereby driving the screw part 422 of the adjusting rod 42, which is threadedly connected to it, to rotate. Since the screw part 422 is threadedly engaged with the base 41, and the adjusting rod 42 is arranged along the sliding direction of the third plate 33, the rotation of the screw part 422 will drive the sliding rod 42 to rotate. The shaft 421 and the third plate 33 rotatably connected thereto slide along the second plate 32; after the third plate 33 is adjusted to a suitable position, the locking screw 432 passes through the handle 431 and the manual gear 43, and is screwed into the locking hole 412 at the corresponding position of the mounting plate 411 to fix the manual gear 43. At this time, the position of the adjusting rod 42 is fixed and the position of the third plate 33 is locked; the cover 5 on the outside of the power mechanism 4 provides space for the extension and retraction of the adjusting rod 42 and the operation of the manual gear 43 through the through hole 51 and the operating hole 52, and at the same time protects the internal structure, completes the precise adjustment of the third plate 33, and ensures the stable clamping of the support foot by the positioning component.

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The first plate 31, the second plate 32, and the third plate 33 are all inclined upwards towards the center, with positioning holes 11 located on both sides of the second plate 32. The positioning holes 11 are adapted to the positioning protrusions at the bottom of the yeast tray support legs, wherein the inner diameter of the positioning holes 11 is larger than the positioning protrusions. When the legs of the yeast tray rack approach the positioning mechanism 2, the first plate 31, the second plate 32, and the third plate 33, being tilted upwards towards the center, guide the legs towards the positioning holes 11 located on both sides of the second plate 32. As the legs gradually approach the positioning position, the positioning protrusions at the bottom of the legs also approach the positioning holes 11. Since the inner diameter of the positioning hole 11 is larger than that of the positioning protrusion, it provides sufficient clearance for the positioning protrusion to be inserted, facilitating quick alignment and insertion. At the same time, the three tilted plates form a surrounding limit on the legs from different directions, which, in conjunction with the matching of the positioning holes 11 and the positioning protrusions at the bottom of the legs, can firmly fix the legs, effectively preventing the legs from shifting due to external forces, and ensuring the stability and accuracy of the yeast tray rack positioning.

[0034] Working principle: The position of the third plate 33 is adjusted by the power mechanism 4. The manual gear 43 is rotated, which drives the meshing adjusting gear 423 to rotate. This causes the screw part 422 of the adjusting rod 42 to move under the threaded engagement of the base 41 and the L-shaped limiting plate 424, thereby pushing the third plate 33 to slide along the second plate 32 to adapt to the size of different specifications of pallet frame legs. After adjustment, the locking screw 432 is passed through the handle 431 and the manual gear 43 and screwed into the corresponding locking hole 412 of the mounting plate 411 to achieve fixation. Next, align the pallet frame legs with the positioning holes 11. Guided by the inclined guide plate 311 at the end of the first plate 31, the legs slide along the guide plate 311 toward the positioning holes 11. At the same time, the right-angle structure formed by the intersection of the first plate 31 and the second plate 32 initially limits the position of the legs on both sides. The right-angle structure formed by the third plate 33 and the second plate 32 further limits the position from the other side, so that the positioning protrusion at the bottom of the legs accurately enters the positioning holes 11. The stable positioning of the pallet frame is achieved through the combined action of the three positioning plates 3.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
