Description

Technical Field

[0001] This application relates to the field of quick-freezing technology, and in particular to a material conveying device and a quick-freezing machine. Background Technology

[0002] Quick-freezing is a process that rapidly lowers the temperature of food below the temperature at which microorganisms can grow, causing the food to form extremely small ice crystals. This not only preserves the original flavor of the food as much as possible, but also significantly extends its shelf life.

[0003] During the quick-freezing of food, a low-temperature airflow passes through a perforated plate of a conveyor at a sufficiently high velocity from bottom to top. The lift generated by the low-temperature airflow balances the weight of the food, causing it to suspend and move randomly, thus quick-freezing the food. However, for heavier foods, if the velocity of the low-temperature airflow is too slow, the food may not suspend properly, affecting the quality of the quick-frozen food. Utility Model Content

[0004] Therefore, it is necessary to provide a material conveying device to address the problem that food cannot be suspended in traditional technologies, which affects the quality of frozen foods.

[0005] The technical solution is as follows:

[0006] One embodiment provides a material conveying device, comprising:

[0007] The conveying mechanism has a conveying side and a contact side arranged opposite to each other;

[0008] The contact mechanism has a contact arc surface and a contact plane; and

[0009] A rotating mechanism is connected to the contact mechanism. The rotating mechanism can drive the contact mechanism to rotate so that the contact arc surface and the contact plane alternately contact the contact side during one rotation cycle of the rotating mechanism.

[0010] In the aforementioned material conveying device, the rotating mechanism drives the contact mechanism to rotate. During rotation, the contact arc surface and contact plane of the contact mechanism alternately contact the contact side of the conveying mechanism, causing the contact position between the contact side and the contact mechanism to change. This, in turn, causes the conveying side of the conveying mechanism to vibrate. Under this vibration, the material on the conveying side can detach from the conveying side, thus floating and achieving uniform quick-freezing. Compared to traditional technologies, this material conveying device uses the alternating contact between the contact arc surface and contact plane and the conveying mechanism to generate vibration, allowing even heavier materials to detach from the conveying side and float, thereby ensuring the quality of the frozen food.

[0011] In one embodiment, the contact mechanism includes a contact post, the sidewall of which has at least two contact arc surfaces and at least two contact planes, the contact arc surfaces and the contact planes being alternately arranged around the axis of the contact post, and the rotation mechanism being able to drive the contact post to rotate around the axis of the contact post.

[0012] In one embodiment, the rotating mechanism includes a rotating shaft and a driving member. The rotating shaft is connected to the driving member, and the driving member can drive the rotating shaft to rotate. The contact post has an installation channel along its own axis, and the rotating shaft passes through the installation channel.

[0013] In one embodiment, the contact mechanism further includes a positioning element, the contact post having a first positioning hole, the rotating shaft having a second positioning hole, and the positioning element passing through the first positioning hole and the second positioning hole.

[0014] In one embodiment, the contact post is further provided with a third positioning hole, which is coaxially arranged with the first positioning hole, and the positioning element is sequentially inserted through the first positioning hole, the second positioning hole and the third positioning hole.

[0015] In one embodiment, the sidewall of the contact post is provided with a first clearance groove and a second clearance groove. The first positioning hole is formed in the bottom wall of the first clearance groove, and the third positioning hole is formed in the bottom wall of the second clearance groove. The positioning element includes a bolt and a nut. The bolt passes through the first positioning hole, the second positioning hole, and the third positioning hole and is screwed to the nut. The first clearance groove is used to accommodate one of the head of the nut and the head of the bolt, and the second clearance groove is used to accommodate the other of the head of the nut and the head of the bolt.

[0016] In one embodiment, the material conveying device further includes a sensing element and a position sensor, the sensing element being disposed on the rotating mechanism;

[0017] When the position sensor detects that the sensing element is in the stopped position, the contact plane contacts the contact side, and the rotating mechanism can switch from the operating state to the stopped state.

[0018] In one embodiment, the position sensor includes a proximity switch, and the sensing element includes a sensing rod whose axis forms an angle with the rotation axis of the rotating mechanism.

[0019] In one embodiment, the material conveying device further includes a fan capable of blowing air toward the position where the contact mechanism contacts the contact side.

[0020] Another embodiment provides a quick-freezing machine that includes the material conveying device as described above.

[0021] In the aforementioned quick-freezing machine, the rotating mechanism drives the contact mechanism to rotate. During rotation, the contact arc surface and contact plane of the contact mechanism alternately contact the contact side of the conveying mechanism, causing the conveying mechanism to vibrate and causing the material on the conveying side to detach from the conveying side. This allows the material to float and is then quickly frozen uniformly. Compared to traditional technologies, this quick-freezing machine uses the alternating contact between the contact arc surface and contact plane and the conveying mechanism to cause the conveying mechanism to vibrate, enabling even heavier materials to detach from the conveying side of the conveying mechanism and float, thereby ensuring the quality of the quick-frozen food.

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0035] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0036] Please see Figures 1 to 3 One embodiment of this application provides a material conveying device, including a conveying mechanism 100, a contacting mechanism 200, and a rotating mechanism 300. The conveying mechanism 100 has a conveying side 110 and a contacting side 120 disposed opposite to each other. The contacting mechanism 200 has a contact arc surface 211 and a contact plane 212. The rotating mechanism 300 is connected to the contacting mechanism 200 and can drive the contacting mechanism 200 to rotate so that the contact arc surface 211 and the contact plane 212 alternately contact the contacting side 120 within one rotation cycle of the rotating mechanism.

[0037] In the aforementioned material conveying device, the rotating mechanism drives the contact mechanism 200 to rotate. During rotation, the contact arc surface 211 and contact plane 212 of the contact mechanism 200 alternately contact the contact side 120 of the conveying mechanism 100, causing the contact position between the contact side 120 and the contact mechanism 200 to change. This, in turn, causes the conveying side 110 of the conveying mechanism 100 to vibrate. At this time, the material on the conveying side 110 can detach from the conveying side 110 under vibration, thus allowing the material to float and achieve uniform quick freezing. Compared with traditional technology, the aforementioned material conveying device uses the alternating contact between the contact arc surface 211 and contact plane 212 and the conveying mechanism 100 to cause the conveying mechanism 100 to vibrate, enabling even heavier materials to detach from the conveying side 110 of the conveying mechanism 100 and float, thereby ensuring the quality of the frozen food.

[0038] As an explanation, since the contact arc surface 211 and the contact plane 212 have different shapes, when the contact mechanism 200 rotates, the contact position between the contact arc surface 211 and the contact side 120 is different from the contact position between the contact plane 212 and the contact side 120. When the rotating mechanism 300 drives the contact mechanism 200 to rotate, the contact side 120 can reciprocate along the direction of the contact mechanism 200 toward the conveying mechanism 100. When the rotating mechanism increases its rotation speed, the moving speed of the contact side 120 also increases, which eventually causes the conveying mechanism 100 to vibrate, thereby causing the material on the conveying side 110 to vibrate together.

[0039] Please see Figure 2 and Figure 3 In one embodiment, the conveying mechanism 100 includes a conveyor belt with a contact side 120 and a conveying side 110 on opposite sides. The conveying side 110 is used to convey materials. When the conveyor belt moves, the materials also move with the conveyor belt, thereby realizing the conveying of materials.

[0040] Furthermore, the contact arc surface 211 and contact plane 212 of the contact mechanism 200 can alternately contact the contact side 120 of the conveyor belt so that the conveyor belt can vibrate along the height direction, thereby suspending the material on the conveyor side 110.

[0041] Please see Figure 2 and Figure 3 In one embodiment, the material conveying device further includes a fan 400, which is capable of blowing air toward the position where the contact mechanism 200 contacts the contact side 120.

[0042] The blower 400 can blow air toward the position where the contact mechanism 200 contacts the contact side 120 to generate lift on the material on the conveying side 110, so that the material is removed from the contact side 120.

[0043] Furthermore, the conveyor belt of the conveying mechanism 100 is a mesh belt with several ventilation holes. The air delivered by the blower 400 can flow from the contact side 120 to the conveying side 110 through the ventilation holes, so as to drive the material away from the contact side 120.

[0044] In addition, the blower 400 can improve the airflow speed near the material to further enhance the quick-freezing effect.

[0045] Please see Figure 2 In one embodiment, at least two fans 400 are provided, and all fans 400 blow air toward the position where the contact mechanism 200 contacts the contact side 120 to increase the airflow.

[0046] exist Figure 2 and Figure 3In the embodiment shown, the fan 400 is a centrifugal fan, and the centrifugal fan has two positions that both send air towards the contact mechanism 200 and the contact side 120.

[0047] Furthermore, the distances between the two centrifugal fans and the contact mechanism 200 are equal, so that the contact mechanism 200 and the contact side 120 can receive the maximum air volume, thereby achieving the best effect of quick freezing of materials.

[0048] Furthermore, the two adjacent centrifugal fans rotate in opposite directions so that the airflow of the two adjacent centrifugal fans is opposite, thereby maximizing the airflow at the contact point between the contact mechanism 200 and the contact side 120, thus improving the quick-freezing effect.

[0049] Please see Figure 1 and Figure 5 In one embodiment, the contact mechanism 200 includes a contact post 210, the sidewall of which has at least two contact arc surfaces 211 and at least two contact planes 212. The contact arc surfaces 211 and the contact planes 212 are alternately arranged around the axis of the contact post 210. The rotation mechanism 300 can drive the contact post 210 to rotate around the axis of the contact post 210.

[0050] With this configuration, when the rotating mechanism 300 drives the contact column 210 to rotate around its own axis, the contact arc surface 211 and the contact plane 212 of the side wall of the contact column 210 can alternately contact the contact side 120, thereby driving the conveying mechanism 100 to vibrate.

[0051] Furthermore, in this application, the conveying mechanism 100 is driven to vibrate by the alternating contact between the contact arc surface 211 and the contact plane 212 and the contact side 120. During this process, the conveying side 110 and the contact mechanism 200 are not in point contact. Therefore, it is possible to prevent the contact mechanism 200 from making point contact with the conveying side 110 and causing excessive friction, which could lead to damage to the conveying side 110.

[0052] Please see Figure 1 and Figure 5 In one embodiment, the sidewall of the contact post 210 has two contact arc surfaces 211 and two contact planes 212.

[0053] Furthermore, the contact plane 212 of the side wall of the contact post 210 is obtained by cutting the post body flat, which will not be described in detail here.

[0054] Please see Figure 1 and Figure 5In one embodiment, the rotating mechanism 300 includes a rotating shaft 310 and a driving member 320. The rotating shaft 310 is connected to the driving member 320, and the driving member 320 can drive the rotating shaft 310 to rotate. The contact post 210 has an installation channel 217 along its own axis, and the rotating shaft 310 passes through the installation channel 217.

[0055] The rotating shaft 310 passes through the mounting channel 217 of the contact post 210 to achieve the connection between the contact post 210 and the rotating shaft 310. In this way, when the driving member 320 drives the rotating shaft 310 to rotate, the contact post 210 can also rotate along its own axis, thereby achieving alternating contact between the contact arc surface 211 and the contact plane 212 and the contact side 120.

[0056] Further, please refer to Figure 1 and Figure 3 Multiple contact columns 210 are provided, and the multiple contact columns 210 are spaced apart along the axis of the rotating shaft 310. The multiple contact columns 210 can improve the support stability of the contact side 120 of the conveying mechanism 100, so that the vibration position of the conveying side 110 of the conveying mechanism 100 is more uniform, thereby improving the uniformity of quick-freezing materials.

[0057] Please see Figure 1 , Figure 4 and Figure 5 In one embodiment, the contact mechanism 200 further includes a positioning element 220, the contact post 210 has a first positioning hole 213, the rotating shaft 310 has a second positioning hole 311, and the positioning element 220 passes through the first positioning hole 213 and the second positioning hole 311.

[0058] The positioning element 220 passes through the first positioning hole 213 of the contact post 210 and the second positioning hole 311 of the rotating shaft 310 to position the contact post 210, prevent relative rotation between the contact post 210 and the rotating shaft 310 from affecting the rotation of the contact post 210, and thereby improve the vibration stability of the conveying side 110.

[0059] Further, please refer to Figure 5 The first positioning hole 213 is opened on the side wall of the contact post 210.

[0060] Optionally, the first positioning hole 213 can be formed on the contact arc surface 211 or on the contact plane 212, without specific limitation.

[0061] exist Figure 5 In the embodiment shown, the first positioning hole 213 is formed on the contact plane 212 to facilitate the insertion of the positioning member 220.

[0062] Please see Figure 1 , Figure 3 and Figure 5In one embodiment, the contact post 210 is also provided with a third positioning hole 214, which is coaxially arranged with the first positioning hole 213. The positioning member 220 is sequentially inserted through the first positioning hole 213, the second positioning hole 311 and the third positioning hole 214.

[0063] The third positioning hole 214 is coaxially arranged with the first positioning hole 213 so that the positioning member 220 can pass through the first positioning hole 213, the second positioning hole 311 and the third positioning hole 214 and position the contact post 210, thereby improving the connection strength between the contact post 210 and the rotating shaft 310.

[0064] Furthermore, at least two first positioning holes 213 are provided and spaced apart along the axis of the contact post 210, and at least two third positioning holes 214 are provided and spaced apart along the axis of the contact post 210. The third positioning holes 214 are provided in a one-to-one correspondence with the first positioning holes 213, and at least two positioning members 220 are provided and are provided in a one-to-one correspondence with the first positioning holes 213, so as to further improve the connection strength between the contact post 210 and the rotating shaft 310.

[0065] Optionally, the third positioning hole 214 can be formed on the contact arc surface 211 or on the contact plane 212, without specific limitation.

[0066] exist Figure 5 In the embodiment shown, the third positioning hole 214 is formed on the contact plane 212 to facilitate the insertion of the positioning member 220.

[0067] Please see Figure 1 , Figure 4 and Figure 5 In one embodiment, the sidewall of the contact post 210 is provided with a first clearance groove 215 and a second clearance groove 216. A first positioning hole 213 is provided in the bottom wall of the first clearance groove 215, and a third positioning hole 214 is provided in the bottom wall of the second clearance groove 216. The positioning member 220 includes a bolt and a nut. The bolt passes through the first positioning hole 213, the second positioning hole 311 and the third positioning hole 214 and is screwed to the nut. The first clearance groove 215 is used to accommodate one of the heads of the nut and the bolt, and the second clearance groove 216 is used to accommodate the other of the heads of the nut and the bolt.

[0068] The contact post 210 is installed on the rotating shaft 310 by means of threaded engagement between bolts and nuts, which is low-cost and reliable. By opening a first relief groove 215 and a second relief groove 216 on the side wall of the contact post 210, and opening a first positioning hole 213 and a third positioning hole 214 on the bottom wall of the first relief groove 215 and the bottom wall of the second relief groove 216 respectively, when the bolt passes through the first positioning hole 213 and the third positioning hole 214 and is screwed with the nut, the first relief groove 215 and the second relief groove 216 can accommodate the head of the bolt or the nut. This prevents the head of the bolt or the nut from protruding from the side wall of the contact post 210 and causing scratches or damage to the contact side 120 of the conveying mechanism 100 when the contact post 210 contacts the contact side 120 of the conveying mechanism 100.

[0069] Furthermore, both the first clearance groove 215 and the second clearance groove 216 are formed on the contact plane 212 to prevent the contact arc surface 211 from scratching the contact side 120 of the conveying mechanism 100 when it comes into contact with the contact side 120, thereby protecting the conveying mechanism 100.

[0070] Please see Figure 1 In one embodiment, the material conveying device further includes a sensing element 500 and a position sensor 600, with the sensing element 500 disposed on the rotating mechanism 300;

[0071] When the position sensor 600 senses that the sensing element 500 is in the stopped position, the contact plane 212 contacts the contact side 120, and the rotating mechanism 300 can switch from the operating state to the stopped state.

[0072] The sensing element 500 is disposed on the rotating mechanism 300 and rotates together with the rotating mechanism 300. The position sensor 600 can sense the position of the sensing element 500. When the position sensor 600 senses that the sensing element 500 is in the stopped position, the contact plane 212 contacts the contact side 120. At this time, the rotating mechanism 300 can switch from the operating state to the stopped state. Thus, when the rotating mechanism 300 is in the stopped state, the contact mechanism 200 is exactly located at the position where the contact plane 212 can contact the contact side 120. At this time, the contact arc surface 211 does not contact the contact side 120 to avoid damage to the conveying mechanism 100 caused by the contact arc surface 211 contacting the contact side 120 when the rotating mechanism 300 is stopped.

[0073] As an explanation, since the distance between the axis of the contact arc surface 211 and the axis of the contact post 210 is greater than the distance between the axis of the contact plane 212 and the axis of the contact post 210, when the contact arc surface 211 contacts the contact side 120, the conveying side 110 rises, and when the contact plane 212 contacts the contact side 120, the conveying side 110 falls. Through the rotation of the contact post 210, the conveying side 110 vibrates in the height direction. When the rotating mechanism 300 stops, both the contact arc surface 211 and the contact plane 212 of the contact post 210 may contact the contact side 120. When the contact arc surface 211 contacts the contact side 120, the conveying side 110 is located at the highest point of vibration. At this time, the conveying mechanism 100 as a whole experiences a large resisting force from the contact arc surface 211, causing the conveying side 110 to vibrate more. The conveying mechanism 100 deforms, and prolonged deformation of the conveying mechanism 100 will cause a decrease in the tension of the conveying mechanism 100, resulting in a decrease in the conveying stability of the conveying mechanism 100. In this embodiment, the position sensor 600 is used to sense the position of the sensing element 500. When the position sensor 600 senses that the position of the sensing element 500 is in the stopped position, the contact plane 212 of the contact column 210 that rotates with the sensing element 500 just contacts the contact side 120. When the contact plane 212 contacts the contact side 120, the conveying side 110 is located at the low point of vibration. At this time, the conveying mechanism 100 is subjected to a small abutment force from the contact plane 212, and the conveying mechanism 100 will not produce excessive deformation, thereby improving the conveying stability of the conveying mechanism 100 in the subsequent conveying process.

[0074] Furthermore, the position sensor 600 is installed inside the quick-freezing machine and close to the material conveying device to ensure the sensing effect of the position sensor.

[0075] Please see Figure 1 In one embodiment, the position sensor 600 includes a proximity switch, and the sensing element 500 includes a sensing rod whose axis forms an angle with the rotation axis of the rotation mechanism 300.

[0076] With this configuration, when the rotating mechanism 300 rotates, the sensing rod can rotate together with the rotating mechanism 300. The axis of the sensing rod forms an angle with the rotation axis of the rotating mechanism 300, so that when the rotating mechanism 300 rotates, the position of the end of the sensing rod away from the rotating mechanism 300 will change. The proximity switch can detect the approach of the sensing rod. When the proximity switch senses the approach of the sensing rod, it means that the contact post 210 has rotated to the position where the contact plane 212 contacts the contact side 120. At this time, after the rotating mechanism 300 stops, the conveying mechanism 100 is subjected to a smaller abutting force from the contact plane 212, thus avoiding excessive deformation of the conveying mechanism 100.

[0077] Furthermore, when the proximity switch detects that the end of the sensing rod furthest from the rotating shaft 310 is closest to itself, it indicates that the sensing rod is in the stop position. The contact post 210 rotates to the position where the contact plane 212 contacts the contact side 120. At this time, after the rotating mechanism 300 stops, the conveying mechanism 100 finds that the contact force from the contact plane 212 is small, thus avoiding excessive deformation of the conveying mechanism 100.

[0078] Further, please refer to Figure 1 One end of the rotating shaft 310 is connected to the drive component 320, and the other end of the rotating shaft 310 is connected to the sensing rod.

[0079] Please see Figure 1 In one embodiment, the drive unit 320 includes a geared motor, the output end of which is connected to the end of the rotating shaft 310 away from the sensing rod to drive the rotating shaft 310 to rotate.

[0080] Another embodiment provides a quick-freezing machine that includes the material conveying device as described above.

[0081] In the aforementioned quick-freezing machine, the rotating mechanism drives the contact mechanism 200 to rotate. During rotation, the contact arc surface 211 and contact plane 212 of the contact mechanism 200 alternately contact the contact side 120 of the conveying mechanism 100, causing the conveying mechanism 100 to vibrate and causing the material on the conveying side 110 to detach from the conveying side 110, thereby enabling the material to float and achieve uniform quick-freezing. Compared with traditional technology, the aforementioned quick-freezing machine uses the alternating contact between the contact arc surface 211 and contact plane 212 and the conveying mechanism 100 to cause the conveying mechanism 100 to vibrate, allowing even heavier materials to detach from the conveying side 110 of the conveying mechanism 100 and float, thus ensuring the quality of the quick-frozen food.

[0082] Furthermore, the quick-freezing machine is equipped with an insulation chamber, and the motor of the quick-freezing machine is located outside the insulation chamber to facilitate heat dissipation of the motor and improve quick-freezing efficiency.

[0083] 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.

[0084] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
