[0011] According to an embodiment of the present invention, a lifting synchronization assembly for a quick-freezing machine comprises a first gear and a second gear connected to the same drive shaft, which are coaxially arranged.

[0012] According to an embodiment of the present invention, a lifting synchronization assembly for a quick-freezing machine includes a first guide member and a second guide member, each comprising a connecting seat, a first partition, and a second partition. The connecting seat is used to connect the cold plate. The first partition and the second partition are spaced apart on the connecting seat, and a mounting position for accommodating a first gear or a second gear is formed between the first partition and the second partition. A through hole is provided on the first partition for the transmission shaft to pass through.

[0013] According to the present invention, in the lifting synchronization assembly for a quick-freezing machine, the widths of the first guide rack and the second guide rack are both smaller than the gap between the first partition and the second partition.

[0014] According to an embodiment of the present invention, a lifting synchronization assembly for a quick-freezing machine includes a first guide member and a second guide member, respectively, a first bearing and a second bearing. The first bearing is disposed in the through hole, and the transmission shaft is rotatably connected to the first partition plate through the first bearing. The second partition plate is provided with a fixing groove for mounting the second bearing, and the first gear or the second gear is rotatably connected to the second partition plate through the second bearing.

[0015] According to an embodiment of the present invention, a lifting synchronization assembly for a quick-freezing machine has a connecting surface on the side of the connecting seat facing away from the first partition plate, and the connecting surface is used to closely adhere to the cold plate; the connecting surfaces of the connecting seats of the same guide assembly are located on the same plane.

[0016] A second aspect of this utility model provides a quick-freezing machine, including a frame, a cold plate, and a lifting synchronization assembly for a quick-freezing machine as described in the first aspect of this utility model; the cold plate is slidably disposed on the frame, a first guide member is connected to a first end of the cold plate, and a second guide member is connected to a second end of the cold plate.

[0033] A quick-freezing machine is a freezing device that rapidly freezes the core temperature of an item to a predetermined temperature within a short period. Quick-freezing machines can be used to quickly freeze blood plasma bags. Related quick-freezing machines include a drive unit and multiple cold plates arranged along the height of the machine. Blood plasma bags are placed between two adjacent cold plates, and under the action of the drive unit, the two adjacent cold plates move relative to each other to clamp and quickly freeze the blood plasma bags. However, the uneven force exerted by the drive unit on different parts of the cold plates can easily cause asynchronous movement at opposite ends of the cold plates during lifting and lowering, leading to jamming or even tilting of the cold plates during movement.

[0034] Reference Figures 1 to 5 The following are several embodiments of the lifting synchronization component for a quick-freezing machine and the quick-freezing machine of this utility model.

[0035] like Figures 1 to 4 As shown, the first aspect of this utility model provides a lifting synchronization assembly for a quick-freezing machine. The lifting synchronization assembly includes a rack assembly 200 and a guide assembly 100. The rack assembly 200 includes a first guide rack 210 and a second guide rack 220, both of which are arranged along the lifting direction of the cold plate 300 of the quick-freezing machine. The guide assembly 100 includes a drive shaft 110, a first connecting assembly 120, and a second connecting assembly 130. A first guide rack 210 is rotatably connected to the first connecting assembly 120 and meshes with the first guide rack 210. The gear 121 is rotatably connected to the second connecting assembly 130, and the second gear 131 meshes with the second guide rack 220. The first connecting assembly 120 is used to connect to the first end 310 of the cold plate 300, and the second connecting assembly 130 is used to connect to the second end 320 of the cold plate 300. The first end 310 and the second end 320 of the cold plate 300 are opposite ends. The drive shaft 110 is connected to the first gear 121 and the second gear 131, so that the first connecting assembly 120 and the second connecting assembly 130 move synchronously with respect to the rack assembly 200.

[0036] During the lifting and lowering of the cold plate 300, the first gear 121 meshes with the first guide rack 210 and the second gear 131 meshes with the second guide rack 220 due to the traction force of the cold plate 300. The transmission shaft 110 is connected to the first gear 121 and the second gear 131. The relative positions of the first gear 121 and the second gear 131 remain unchanged through the transmission shaft 110. Due to the meshing relationship between the first gear 121 and the first guide rack 210 and the second gear 131 and the second guide rack 220, the first connecting assembly 120 and the second connecting assembly 130 move synchronously with respect to the rack assembly 200. This reduces the speed difference between the first end 310 and the second end 320 of the cold plate 300, and makes the first end 310 and the second end 320 of the cold plate 300 move synchronously, thereby reducing the risk of jamming or tilting of the cold plate 300 during the lifting and lowering process.

[0037] like Figure 1 and Figure 4 As shown, the first guide rack 210 and the second guide rack 220 are both arranged along the lifting direction of the cold plate 300 of the quick-freezing machine. The first gear 121 meshes with the first guide rack 210 under the traction force of the first end 310 of the cold plate 300, and the second gear 131 meshes with the second guide rack 220 under the traction force of the second end 320 of the cold plate 300. If the movement of the first end 310 and the second end 320 of the cold plate 300 is not synchronized, the traction force on the first connecting assembly 120 and the second connecting assembly 130 will be different. The transmission shaft 110 can be used to balance the forces on the first connecting assembly 120 and the second connecting assembly 130, so that the first connecting assembly 120 and the second connecting assembly 130 are relatively... The rack and pinion assembly 200 moves synchronously; for example, the traction force on the first connecting assembly 120 is greater than that on the second connecting assembly 130, and the drive shaft 110 transmits the traction force on the first connecting assembly 120 to the second connecting assembly 130, so that the forces on the first connecting assembly 120 and the second connecting assembly 130 tend to be consistent; since the first end 310 of the cold plate 300 is connected to the first connecting assembly 120 and the second end 320 of the cold plate 300 is connected to the second connecting assembly 130, the synchronous movement of the first connecting assembly 120 and the second connecting assembly 130 can drive the first end 310 and the second end 320 of the cold plate 300 to move synchronously, effectively reducing the risk of jamming or tilting of the cold plate 300 during the lifting and lowering process.

[0038] Among them, such as Figure 4As shown, the first end 310 and the second end 320 of the cold plate 300 are opposite ends. In this paper, the first end 310 of the cold plate 300 is the front end of the cold plate 300, and the corresponding second end 320 of the cold plate 300 is the rear end of the cold plate 300. The lifting synchronization mechanism enables the front end and the rear end of the cold plate 300 to move synchronously, reducing the risk of asynchronous movement of the cold plate 300 during the lifting process. Of course, in other embodiments, the first end 310 of the cold plate 300 can also be the left side of the cold plate 300, and the corresponding second end 320 of the cold plate 300 can be the right side of the cold plate 300. This utility model embodiment does not make any special limitation in this regard.

[0039] like Figure 1 and Figure 2 As shown, the first guide rack 210 and the second guide rack 220 are both arranged along the lifting direction of the cold plate 300 of the quick-freezing machine. In this embodiment of the invention, the rack assembly 200 restricts the movement direction of the first connecting assembly 120 and the second connecting assembly 130, and the transmission shaft 110 restricts the relative positional relationship of the first connecting assembly 120 and the second connecting assembly 130, so that the movement of the first connecting assembly 120 and the second connecting assembly 130 tends to be consistent. The first guide rack 210 and the first gear 121, as well as the second guide rack 220 and the second gear 131, are connected by tooth surface meshing. The tooth surface meshing transmission method has very high transmission accuracy, making the movement of the first connecting assembly 120 and the second connecting assembly 130 more stable, reducing the risk of slippage, and further ensuring the coordination and consistency of the movement of the first connecting assembly 120 and the second connecting assembly 130. Since the meshing contact surface of the gear and rack is large, the load can be evenly distributed, improving the load-bearing capacity of the lifting synchronization mechanism.

[0040] In some embodiments, such as Figure 1 and Figure 2As shown, the first guide rack 210 is provided with a plurality of first meshing teeth, which are arranged on the first guide rack 210 along the lifting direction of the cold plate 300. The second guide rack 220 is provided with a plurality of second meshing teeth, which are arranged on the second guide rack 220 along the lifting direction of the cold plate 300. The number of first meshing teeth and the number of second meshing teeth are equal. The first gear 121 and the second gear 131 have the same number of teeth. The first meshing teeth and the second meshing teeth correspond one-to-one, and the heights of the first meshing teeth and the corresponding second meshing teeth are the same. This makes the first gear 121 meshing with the first meshing teeth and the second gear 131 meshing with the second meshing teeth at the same height, thereby making the first connecting assembly 120 and the second connecting assembly 130 at the same height, reducing the risk of the first end 310 and the second end 320 of the cold plate 300 being misaligned. Of course, the number of teeth of the first meshing teeth and the second meshing teeth, as well as the number of teeth of the first gear 121 and the second gear 131, can also be different. This embodiment of the present invention does not impose any particular limitation on this.

[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, the guide assembly 100 is provided with at least two sets, and the guide assembly 100 corresponds one-to-one with the cold plate 300. Through multiple sets of guide assemblies 100, the movement of multiple cold plates 300 of the quick-freezing machine can be guided, improving the stability of the cold plate 300 during the lifting and lowering process, thereby ensuring the normal operation of the quick-freezing machine.

[0042] Since multiple cold plates 300 are arranged along the height direction of the blast freezer, that is, multiple cold plates 300 are arranged along their own lifting direction, at least two sets of guide components 100 are arranged along the lifting direction of the cold plates 300 so that the guide components 100 connect to the corresponding cold plates 300; the first guide rack 210 and the second guide rack 220 are both arranged along the lifting direction of the cold plates 300 of the blast freezer, and at least two sets of guide components 100 are arranged along the lifting direction of the cold plates 300, which is more conducive to the cooperation between the first guide rack 210 and the first gear 121 of the multiple guide components 100 and the second guide rack 220 and the second gear 131 of the multiple guide components 100. Only one first guide rack 210 is needed. A 10 and a second guide rack 220 can drive the first gear 121 and the second gear 131 of multiple guide components 100 to rotate, so as to ensure the stability and consistency of the lifting and lowering movement of multiple cold plates 300. In this embodiment, the first connecting components 120 of multiple guide components 100 are arranged along the lifting and lowering direction of the cold plate 300. Under the premise of ensuring that the first guide rack 210 meshes with the first gear 121 of multiple first connecting components 120, the above arrangement can minimize the width of the first guide rack 210, reduce the material used, and enhance the stability of the movement of the first connecting components 120. Similarly, the second connecting components 130 of multiple guide components 100 are arranged along the lifting and lowering direction of the cold plate 300.

[0043] In some embodiments, such as Figure 3 As shown, the first gear 121 and the second gear 131 connected to the same transmission shaft 110 are coaxially arranged, which can reduce energy loss caused by asymmetry, improve the transmission efficiency of the transmission shaft 110, and facilitate the synchronous rotation of the first gear 121 and the second gear 131 under the action of the transmission shaft 110; wherein, the first gear 121, the second gear 131 and the transmission shaft 110 are coaxially arranged to improve the stability of the movement of the guide assembly 100.

[0044] In some embodiments, such as Figure 3As shown, the first connecting assembly 120 and the second connecting assembly 130 respectively include a connecting seat 140, a first bearing seat 150, and a second bearing seat 160. The connecting seat 140 is used to connect the cold plate 300. During the lifting and lowering process of the cold plate 300, the cold plate 300 applies a traction force to the connecting seat 140 of the first connecting assembly 120 and the second connecting assembly 130, causing the first connecting assembly 120 and the second connecting assembly 130 to move with the cold plate 300. The first bearing seat 150 and the second bearing seat 160 are spaced apart on the connecting seat 140, and a mounting position 170 for accommodating the first gear 121 or the second gear 131 is formed between the first bearing seat 150 and the second bearing seat 160. The first bearing seat 150 and the second bearing seat 160 can protect the first gear 121. The function of the first gear 121 and the second gear 131 is to reduce the probability of direct contact between the first gear 121 and the second gear 131 and other components, thereby reducing wear and extending the service life of the first gear 121 and the second gear 131; the first bearing housing 150 is provided with a through hole 151 for the transmission shaft 110 to pass through. One end of the transmission shaft 110 passes through the through hole 151 of the first connecting assembly 120 and is connected to the first gear 121, and the other end passes through the through hole 151 of the second connecting assembly 130 and is connected to the second gear 131; the end of the first gear 121 away from the transmission shaft 110 is rotatably connected to the second bearing housing 160 of the first connecting assembly 120, and the end of the second gear 131 away from the transmission shaft 110 is rotatably connected to the second bearing housing 160 of the second connecting assembly 130.

[0045] In some embodiments, such as Figure 3 As shown, the first connecting assembly 120 and the second connecting assembly 130 respectively further include a first bearing 180 and a second bearing 190. The first bearing 180 is disposed in the through hole 151, and the drive shaft 110 is rotatably connected to the first bearing seat 150 through the first bearing 180. The first bearing 180 supports the drive shaft 110, which can reduce the friction between the drive shaft 110 and the first bearing seat 150 and improve the rotational stability of the drive shaft 110. The second bearing seat 160 is provided with a fixing groove 161 for mounting the second bearing 190. The first gear 121 or the second gear 131 is rotatably connected to the second bearing seat 160 through the second bearing 190. The fixing groove 161 fixes the second bearing 190, and the second bearing 190 supports the first gear 121 or the second gear 131, which can reduce the friction between the first gear 121 and the second bearing seat 160 or between the second gear 131 and the second bearing seat 160 and improve the rotational stability of the first gear 121 or the second gear 131.

[0046] In some embodiments, the first bearing housing 150 and the second bearing housing 160 are integrally formed and have a common fixed connection with a horizontal plate, forming a U-shaped irregular bearing housing.

[0047] In some embodiments, such as Figure 1 and Figure 2 As shown, the widths of the first guide rack 210 and the second guide rack 220 are both smaller than the gap between the first bearing housing 150 and the second bearing housing 160, which can reduce the obstruction of the first bearing housing 150 and the second bearing housing 160 to the first guide rack 210 or the second guide rack 220, and facilitate the meshing of the first guide rack 210 and the first gear 121 or the meshing of the second guide rack 220 and the second gear 131.

[0048] In some embodiments, the widths of the first guide rack 210 and the second guide rack 220 are smaller than the gap between the first bearing housing 150 and the second bearing housing 160. The first guide rack 210 is located within the mounting position 170 of the first connecting assembly 120, and the second guide rack 220 is located within the mounting position 170 of the second connecting assembly 130. This can limit the relative displacement between the first guide rack 210 and the first gear 121 or between the second guide rack 220 and the second gear 131, so as to ensure stable meshing between the first guide rack 210 and the first gear 121 or between the second guide rack 220 and the second gear 131.

[0049] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the connecting seat 140 has a connecting surface 141 on the side facing away from the first bearing seat 150. The connecting surface 141 is used to closely adhere to the cold plate 300, making the connection between the connecting seat 140 and the cold plate 300 more reliable. Generally, the connecting seat 140 is connected to the side of the cold plate 300, and the side of the cold plate 300 is usually flat. The first connecting assembly 120 is connected to the first end 310 of the cold plate 300, and the second connecting assembly 130 is connected to the second end 320 of the cold plate 300. The connecting surfaces 141 of the connecting seats 140 of the same guide assembly 100 are located on the same plane, so that the connecting seats 140 of the first connecting assembly 120 and the connecting seats 140 of the second connecting assembly 130 can both fit against the side of the cold plate 300, improving the stability of the guide assembly 100.

[0050] A second aspect of this utility model provides a quick-freezing machine, such as... Figure 4 As shown, the quick-freezing machine includes a frame 400, a cold plate 300, and a lifting synchronization assembly for the quick-freezing machine according to the first aspect embodiment described above; the cold plate 300 is slidably disposed on the frame 400, a first connecting assembly 120 is connected to a first end 310 of the cold plate 300, and a second connecting assembly 130 is connected to a second end 320 of the cold plate 300.

[0051] It is understood that since the lifting synchronization component for the quick-freezing machine has the beneficial effects of the above embodiments, the quick-freezing machine will have the beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and this application will not repeat it.

[0052] In some embodiments, such as Figure 4 As shown, a guide shaft 410 is provided on the frame 400, and the guide shaft 410 is arranged along the lifting direction of the cold plate 300; the cold plate 300 is provided with an opening for the guide shaft 410 to pass through, and the cold plate 300 is slidably arranged on the frame 400 through the guide shaft 410.

[0053] like Figure 4 and Figure 5 As shown, the quick-freezing machine also includes a suspension rod 420, which is arranged along the lifting direction of the cold plates 300. One end of the suspension rod 420 is installed on one of the adjacent cold plates 300, and the other end is installed on the other cold plate 300. A sliding groove 421 is provided on the suspension rod 420, which is arranged along the length of the suspension rod 420. A sliding block 350 is provided on the side of the cold plate 300, and the sliding block 350 is slidably disposed in the sliding groove 421. When the two adjacent cold plates 300 move relative to each other, the sliding block 350 slides in the sliding groove 421. The suspension rod 420 can guide the movement direction of the cold plates 300, so that the cold plates 300 can be lifted and lowered stably. In addition, the suspension rod 420 can limit the distance between the two adjacent cold plates 300, preventing the distance between the two adjacent cold plates 300 from being too large. Two hangers 420 can be installed side by side between two adjacent cold plates 300 to enhance the restraining effect of the hangers 420 on the two adjacent cold plates 300 and improve the stability of the quick-freezing machine operation.

[0054] In some embodiments, such as Figure 4 As shown, two lifting synchronization components are provided. One lifting synchronization component is located on the first side 330 of the cold plate 300, and the other lifting synchronization component is located on the second side 340 of the cold plate 300. The first side 330 and the second side 340 of the cold plate 300 are opposite sides. Through the two lifting components, the movement speed of the first end 310 and the second end 320 of the cold plate 300 can be adjusted from the first side 330 and the second side 340 of the cold plate 300 to ensure that the first end 310 and the second end 320 of the cold plate 300 move synchronously, further reducing the risk of the cold plate 300 jamming or tilting during movement.

[0055] In some embodiments, such as Figure 4As shown, the quick-freezing machine also includes a drive assembly. Multiple cold plates 300 are arranged along the lifting direction of the cold plates 300. The drive assembly drives the cold plate 300 located at the bottom to move. The cold plate 300 at the bottom presses against the other cold plates 300, thereby clamping and freezing the items located between two adjacent cold plates 300.

[0056] In some embodiments, such as Figure 4 As shown, the drive assembly includes two drive components 500. The drive component of one drive component 500 is connected to the first side 330 of the bottommost cold plate 300, and the drive component of the other drive component 500 is connected to the second side 340 of the bottommost cold plate 300. Through the synchronous operation of the two drive components 500, the first side 330 and the second side 340 of the cold plate 300 move synchronously, preventing the cold plate 300 from tilting or shaking during the lifting and lowering process. Generally, the drive component 500 is a cylinder.

[0057] In some embodiments, the drive assembly includes a base, a lead screw, a lead screw nut, a motor, and a scissor lift assembly. The scissor lift assembly includes two cross-arranged support rods rotatably connected. One end of one support rod is fixed to the base, and the other end is slidably mounted on the lowest cold plate 300. One end of the other support rod is fixed to the lowest cold plate 300, and the other end is provided with a slider, which is slidably mounted on the base. The output shaft of the motor is connected to one end of the lead screw, and the lead screw nut is sleeved on the outside of the lead screw and connected to the slider. When the motor operates, it drives the slider to slide on the base through the lead screw and lead screw nut, thereby driving the two support rods to rotate relative to each other, so that the lowest cold plate 300 can rise and fall, improving the stability of the movement of the cold plate 300.

[0058] In some embodiments, such as Figure 4 As shown, the first guide rack 210 and the second guide rack 220 are provided with connecting brackets 230 at both ends. The connecting brackets 230 are connected to the frame 400, so that the first guide rack 210 and the second guide rack 220 can be stably set along the lifting direction of the cold plate 300.

[0059] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
