Description

Technical Field

[0001] The present application relates to the field of quick freezing technology, and in particular to a material conveying device and a quick freezing machine. Background Art

[0002] Quick freezing is a process of rapidly lowering the temperature of food to below the growth temperature of microorganisms, 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 greatly extends the shelf life of the food.

[0003] When quick-freezing food, a low-temperature airflow passes through the perforated plate of the conveyor at a sufficiently high velocity. The lift generated by the low-temperature airflow balances the weight of the food, causing it to suspend and move in a disordered state, thus quickly freezing the food. However, for heavier food, if the low-temperature airflow velocity is too slow, the food will not be able to suspend, affecting the quality of the quick-frozen food. Summary of the Invention

[0004] Based on this, it is necessary to provide a material conveying device to address the problem that food cannot be suspended in traditional technology, which affects the quality of quick-frozen food.

[0005] The technical solution is as follows:

[0009] A rotating mechanism is connected to the contact mechanism, and 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 within one rotation cycle of the rotating mechanism.

[0010] In the above-mentioned material conveying device, the rotating mechanism can drive the contact mechanism to rotate. During the rotation process, the contact arc surface and contact plane of the contact mechanism can alternately contact the contact side of the conveying mechanism, causing the contact side and the contact mechanism to change their contact position, thereby causing the conveying side of the conveying mechanism to vibrate. At this time, the material on the conveying side can break away from the conveying side under the vibration, thereby causing the material to float and evenly quick-freeze the material. Compared with traditional technologies, the above-mentioned material conveying device vibrates the conveying mechanism through alternating contact between the contact arc surface and the contact plane and the conveying mechanism, allowing heavier materials to break away from the conveying side of the conveying mechanism and float, thereby ensuring the quality of quick-frozen food.

[0011] In one embodiment, the contact mechanism includes a contact column, the side wall of the contact column has at least two contact arc surfaces and at least two contact planes, the contact arc surfaces and the contact planes are alternately arranged around the axis of the contact column, and the rotation mechanism can drive the contact column to rotate around the axis of the contact column.

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

[0013] In one embodiment, the contact mechanism further includes a positioning member, the contact column is provided with a first positioning hole, the rotating shaft is provided with a second positioning hole, and the positioning member is passed through the first positioning hole and the second positioning hole.

[0014] In one embodiment, the contact column further defines a third positioning hole, which is coaxial with the first positioning hole. The positioning member passes through the first positioning hole, the second positioning hole, and the third positioning hole in sequence.

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

[0017] When the position sensor senses that the sensing element is located at the stop position, the contact plane contacts the contact side, and the rotating mechanism can be switched from the operating state to the stop state.

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

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

[0020] Another embodiment provides a quick freezer, which 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 this rotation, the contact arc and contact plane of the contact mechanism alternately contact the contact side of the conveying mechanism, causing the conveying mechanism to vibrate and drive the material on the conveying side away from it, thereby allowing the material to float and evenly freeze. Compared to conventional technologies, the aforementioned quick-freezing machine vibrates the conveying mechanism through alternating contact between the contact arc and contact plane and the conveying mechanism, allowing even heavier materials to float away from the conveying side of the conveying mechanism, thereby ensuring the quality of the quick-frozen food.

[0036] See also Figures 1 to 3 An embodiment of the present application provides a material conveying device, including a conveying mechanism 100, a contact mechanism 200 and a rotating mechanism 300, wherein the conveying mechanism 100 has a conveying side 110 and a contact side 120 arranged opposite to each other; the contact mechanism 200 has a contact arc surface 211 and a contact plane 212; the rotating mechanism 300 is connected to the contact mechanism 200, and the rotating mechanism 300 can drive the contact mechanism 200 to rotate so that the contact arc surface 211 and the contact plane 212 alternately contact the contact side 120 within one rotation cycle of the rotating mechanism.

[0037] In the above-mentioned material conveying device, the rotating mechanism can drive the contact mechanism 200 to rotate. During the rotation process, the contact arc surface 211 and the contact plane 212 of the contact mechanism 200 can alternately contact the contact side 120 of the conveying mechanism 100, causing the contact position of the contact side 120 and the contact mechanism 200 to change, thereby causing the conveying side 110 of the conveying mechanism 100 to vibrate. At this time, the material on the conveying side 110 can be separated from the conveying side 110 under the vibration, thereby causing the material to float, and then evenly quick-freeze the material. Compared with conventional technology, the above-mentioned material conveying device causes the conveying mechanism 100 to vibrate by alternating contact between the contact arc surface 211 and the contact plane 212 and the conveying mechanism 100, so that even heavier materials can be separated from the conveying side 110 of the conveying mechanism 100 and float, thereby ensuring the quality of the quick-frozen food.

[0038] For explanation, since the shapes of the contact arc surface 211 and the contact plane 212 are different, when the contact mechanism 200 rotates, the position where the contact arc surface 211 contacts the contact side 120 is different from the position where the contact plane 212 contacts the contact side 120. When the rotating mechanism 300 drives the contact mechanism 200 to rotate, the contact side 120 can move back and forth along the direction of the contact mechanism 200 toward the conveying mechanism 100. When the rotating mechanism accelerates the rotation speed, the moving speed of the contact side 120 also accelerates, eventually causing the conveying mechanism 100 to vibrate, thereby driving the material on the conveying side 110 to vibrate together.

[0039] See also Figure 2 and Figure 3 In one embodiment, the conveying mechanism 100 includes a conveyor belt, and the opposite sides of the conveyor belt are a contact side 120 and a conveying side 110. 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 transportation of materials.

[0040] Furthermore, the contact arc surface 211 and the 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 in the height direction, thereby causing the material on the conveying side 110 to be suspended.

[0041] See also Figure 2 and Figure 3 In one embodiment, the material conveying device further includes a fan 400 , which can supply air toward the position where the contact mechanism 200 contacts the contact side 120 .

[0042] The fan 400 can blow air toward the position where the contact mechanism 200 contacts the contact side 120 , so as to generate a lifting force on the material on the conveying side 110 , so that the material is separated from the contact side 120 .

[0043] Furthermore, the conveyor belt of the conveying mechanism 100 is a mesh belt having a plurality of ventilation holes. The wind sent out by the fan 400 can flow from the contact side 120 to the conveying side 110 through the ventilation holes to drive the material to leave the contact side 120 .

[0044] In addition, the fan 400 can also improve the air flow speed near the material to further improve the quick-freezing effect.

[0045] See also 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 wind force.

[0046] exist Figure 2 and Figure 3In the illustrated embodiment, the fan 400 is a centrifugal fan. Two centrifugal fans are provided and both blow air toward the position where the contact mechanism 200 contacts the contact side 120 .

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

[0048] Furthermore, the rotation directions of the two adjacent centrifugal fans are opposite, so that the wind directions of the two adjacent centrifugal fans are opposite, thereby allowing the position where the contact mechanism 200 contacts the contact side 120 to receive the maximum air volume, thereby improving the quick-freezing effect.

[0049] See also Figure 1 and Figure 5 In one embodiment, the contact mechanism 200 includes a contact column 210, the side wall of the contact column 210 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 column 210, and the rotating mechanism 300 can drive the contact column 210 to rotate around the axis of the contact column 210.

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

[0051] Furthermore, in the present application, the conveying mechanism 100 is driven to vibrate by alternating contact between the contact arc surface 211 and the contact plane 212 and the contact side 120. During this process, there is no point contact between the conveying side 110 and the contact mechanism 200. Therefore, it is possible to prevent the contact mechanism 200 from generating point contact with the conveying side 110 and causing excessive friction, thereby causing damage to the conveying side 110.

[0052] See also Figure 1 and Figure 5 In one embodiment, the sidewall of the contact pillar 210 has two contact arc surfaces 211 and two contact flat surfaces 212 .

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

[0054] See also 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. The driving member 320 can drive the rotating shaft 310 to rotate. The contact column 210 has an installation channel 217 along its own axis, and the rotating shaft 310 is inserted into the installation channel 217.

[0055] The rotating shaft 310 is passed through the mounting channel 217 of the contact column 210 to achieve the connection between the contact column 210 and the rotating shaft 310. In this way, when the driving member 320 drives the rotating shaft 310 to rotate, the contact column 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, see Figure 1 and Figure 3 There are multiple contact columns 210, and the multiple contact columns 210 are arranged on the rotating shaft 310 at intervals 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] See also Figure 1 、 Figure 4 and Figure 5 In one embodiment, the contact mechanism 200 further includes a positioning member 220 , the contact column 210 defines a first positioning hole 213 , the rotating shaft 310 defines a second positioning hole 311 , and the positioning member 220 passes through the first positioning hole 213 and the second positioning hole 311 .

[0058] The positioning member 220 is inserted into the first positioning hole 213 of the contact column 210 and the second positioning hole 311 of the rotating shaft 310 to position the contact column 210, thereby preventing relative rotation between the contact column 210 and the rotating shaft 310 and affecting the rotation of the contact column 210, thereby improving the vibration stability of the conveying side 110.

[0059] Further, see Figure 5 The first positioning hole 213 is opened on the side wall of the contact pillar 210 .

[0060] Optionally, the first positioning hole 213 may be provided on the contact arc surface 211 or on the contact plane 212 , which is not specifically limited here.

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

[0062] See also Figure 1 、 Figure 3 and Figure 5In one embodiment, the contact column 210 further defines a third positioning hole 214 , which is coaxial with the first positioning hole 213 , and the positioning member 220 passes through the first positioning hole 213 , the second positioning hole 311 , and the third positioning hole 214 in sequence.

[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 pin 210 , thereby improving the connection strength between the contact pin 210 and the rotating shaft 310 .

[0064] Furthermore, at least two first positioning holes 213 are provided and are spaced apart along the axis of the contact column 210, at least two third positioning holes 214 are provided and are spaced apart along the axis of the contact column 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 column 210 and the rotating shaft 310.

[0065] Optionally, the third positioning hole 214 may be provided on the contact arc surface 211 or on the contact plane 212 , which is not specifically limited here.

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

[0067] See also Figure 1 、 Figure 4 and Figure 5 In one embodiment, a first avoidance groove 215 and a second avoidance groove 216 are provided on the side wall of the contact column 210, a first positioning hole 213 is provided on the bottom wall of the first avoidance groove 215, and a third positioning hole 214 is provided on the bottom wall of the second avoidance groove 216. The positioning member 220 includes a bolt and a nut, the bolt is passed through the first positioning hole 213, the second positioning hole 311 and the third positioning hole 214 and is threadedly connected to the nut, the first avoidance groove 215 is used to accommodate one of the nut and the bolt head, and the second avoidance groove 216 is used to accommodate the other of the nut and the bolt head.

[0068] The contact column 210 is installed on the rotating shaft 310 by threaded cooperation between the bolt and the nut, with low implementation cost and reliable installation effect; by opening a first avoidance groove 215 and a second avoidance groove 216 on the side wall of the contact column 210, and opening a first positioning hole 213 and a third positioning hole 214 on the bottom wall of the first avoidance groove 215 and the bottom wall of the second avoidance groove 216 respectively, so that when the bolt passes through the first positioning hole 213 and the third positioning hole 214 and is screwed to the nut, the first avoidance groove 215 and the second avoidance groove 216 can accommodate the head of the bolt or the nut, so that when the contact column 210 contacts the contact side 120 of the conveying mechanism 100, the head of the bolt or the nut is prevented from protruding from the side wall of the contact column 210 and causing scratches and damage to the contact side 120 of the conveying mechanism 100.

[0069] Furthermore, the first avoidance groove 215 and the second avoidance groove 216 are both 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 contacting the contact side 120 , thereby protecting the conveying mechanism 100 .

[0070] See also Figure 1 In one embodiment, the material conveying device further includes a sensing member 500 and a position sensor 600 , wherein the sensing member 500 is provided on the rotating mechanism 300 ;

[0071] When the position sensor 600 senses that the sensing element 500 is located at the stop position, the contact plane 212 contacts the contact side 120 , and the rotating mechanism 300 can be switched from the operating state to the stop state.

[0072] The sensing member 500 is provided on the rotating mechanism 300 and rotates together with the rotating mechanism 300. The position sensor 600 can sense the position of the sensing member 500. When the position sensor 600 senses that the sensing member 500 is in the stop 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 stop state. In this way, when the rotating mechanism 300 is in the stop 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, so as to avoid the contact arc surface 211 contacting the contact side 120 when the rotating mechanism 300 is stopped and causing damage to the conveying mechanism 100.

[0073] As an explanation, since the distance between the contact arc surface 211 and the axis of the contact column 210 is greater than the distance between the contact plane 212 and the axis of the contact column 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. The rotation of the contact column 210 realizes the vibration of the conveying side 110 in the height direction. When the rotating mechanism 300 stops, the contact arc surface 211 and the contact plane 212 of the contact column 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 vibration high point. At this time, the conveying mechanism 100 as a whole is subjected to a large abutment force from the contact arc surface 211, which makes the conveying The conveying mechanism 100 is deformed. Long-term deformation of the conveying mechanism 100 will cause the tension of the conveying mechanism 100 to decrease, 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 member 500. When the position sensor 600 senses that the position of the sensing member 500 is in the stop position, the contact plane 212 of the contact column 210 that rotates with the sensing member 500 just contacts the contact side 120. When the contact plane 212 contacts the contact side 120, the conveying side 110 is 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 arranged inside the quick-freezing machine and close to the material conveying device to ensure the sensing effect of the position sensor.

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

[0076] With such an arrangement, when the rotating mechanism 300 rotates, the sensing rod can rotate along with the rotating mechanism 300, and 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, and the proximity switch can detect the approach of the sensing rod. When the proximity switch senses the approach of the sensing rod, it indicates that the contact column 210 has rotated to a 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 small abutment force from the contact plane 212, thereby avoiding excessive deformation of the conveying mechanism 100.

[0077] Furthermore, when the proximity switch detects that the distance between the end of the sensing rod away from the rotating shaft 310 and itself is the shortest, it indicates that the sensing rod is in the stop position, and the contact column 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 abutment force from the contact plane 212 is small, thereby avoiding excessive deformation of the conveying mechanism 100.

[0078] Further, see Figure 1 One end of the rotating shaft 310 is connected to the driving member 320, and the other end of the rotating shaft 310 is connected to the sensing rod.

[0079] See also Figure 1 In one embodiment, the driving member 320 includes a reduction motor, and an output end of the reduction motor is connected to an 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 freezer, which includes the material conveying device as described above.

[0081] In the quick-freezing machine described above, the rotating mechanism can drive the contact mechanism 200 to rotate. During rotation, the contact arc surface 211 and contact plane 212 of the contact mechanism 200 can alternately contact the contact side 120 of the conveying mechanism 100, causing the conveying mechanism 100 to vibrate and drive the material on the conveying side 110 to separate from the conveying side 110, thereby allowing the material to float and evenly freeze. Compared to conventional technologies, the quick-freezing machine described above vibrates the conveying mechanism 100 through alternating contact between the contact arc surface 211 and contact plane 212 and the conveying mechanism 100, allowing even heavier materials to separate from the conveying side 110 of the conveying mechanism 100 and float, thereby ensuring the quality of the quick-frozen food.

[0082] Furthermore, the quick-freezing machine is provided with an insulation chamber, and the motor of the quick-freezing machine is arranged 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 arbitrarily. In order to make the description concise, 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 the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application.
