Description

Technical Field

[0001] The present invention belongs to the technical field of conveyor chains, and particularly relates to a metal wear-resistant conveyor chain for refrigeration equipment and its working method. Background Art

[0002] In order to ensure the sustainable and automated operation of refrigeration equipment, conveyor chains are usually used for batch transportation, and the conveyor chain is composed of a chain and a power component.

[0003] After retrieval, a patent document with the publication number CN118833567A, publication date of October 25, 2024, and titled "A Cooling Conveyor with Adjustable Conveyor Chain Spacing" is cited. It includes two limit side plates arranged inside the frame, which are installed on parallel linear guide rails, a bidirectional lead screw, and a transmission shaft. The limit side plates are connected to the linear guide rails by linear bearings, so that the limit side plates can slide on the linear guide rails while ensuring the relative parallelism of the two limit side plates. The limit side plates are connected to the bidirectional lead screw by nuts. Controlling the rotation and stop of the bidirectional lead screw can control the relative position of the two limit side plates. The transmission wheels installed on the limit side plates are connected to the transmission shaft by a sliding key structure. The transmission shaft can transmit torque to the transmission wheel while enabling the transmission wheel to slide on the transmission shaft. In the above embodiment, the stop position of the adjustment motor is controlled by a photoelectric switch to achieve automatic control of the setting of the conveyor chain spacing. When the automatic adjustment mechanism fails, the spacing between the two conveyor chains can also be adjusted with an adjustment handwheel.

[0004] However, the above embodiment still has the following defects:

[0005] The conveyor chain is usually made of metal. During use, due to long-term rotational friction, a lot of metal debris is easily generated. These metal debris are easily adsorbed on the objects to be frozen, resulting in a decline in the quality of the objects to be frozen. At the same time, they are also easily dropped into the gaps of the power components, affecting the smooth operation of the chain and causing damage to the chain. Summary of the Invention

[0009] Furthermore, several groups of transport components are arranged at equal intervals in the gap between the two groups of chains, and the transport components include a horizontally arranged outer cross tube, both ends of the outer cross tube are respectively installed on the two groups of chains, an inner cross tube is arranged in the cavity of the outer cross tube, and the inner cross tube and the outer cross tube are both made of heat-conducting material.

[0010] Furthermore, a frame tube is sleeved on the outer wall of the outer transverse tube, and a plurality of groups of crescent grooves are distributed in a ring array on the outer wall of the frame tube. The port cross-section of the crescent groove is a fan-shaped structure, and a plurality of groups of micropores are evenly distributed on the crescent groove. The end of the micropore away from the opening is connected to the cavity of the outer transverse tube.

[0011] Furthermore, a main rotating shaft is provided between two adjacent groups of the frame tubes, and both ends of the main rotating shaft are rotatably connected to two groups of chains respectively. An upward flip baffle is provided on the top of the main rotating shaft, and a plurality of groups of frame blocks are arranged at equal intervals on both sides of the main rotating shaft. The frame blocks are hinged to the main rotating shaft, and a V-shaped through groove is opened at the center of the frame block.

[0012] Furthermore, both upper and lower ends of the V-shaped through groove are open structures, and the inner diameter of the top opening of the V-shaped through groove is larger than the inner diameter of the bottom opening.

[0013] Furthermore, the rust removal unit also includes a motor bracket; the outer fixed tube is installed at one end of the motor bracket close to the chain; the base of the vibration motor is installed in the motor bracket; and a reinforcement rod is transmission-connected to the output end of the vibration motor, and the other end of the reinforcement rod is installed on the inner vibration tube.

[0014] Furthermore, the cleaning mechanism also includes a brush body mounting strip, and the base of the cleaning brush body is mounted on the brush body mounting strip.

[0015] Furthermore, the heating unit comprises a heating tube, the diameter at the center of the heating tube is larger than the diameter of the openings at both ends; and a third transverse groove is provided on the outer wall of the heating tube on the same side as the first transverse groove.

[0016] Furthermore, a plurality of groups of temperature conducting components are distributed in a circular array on the inner wall of the heating cylinder; a plurality of groups of temperature conducting ports are installed on the temperature conducting components; and the output end of each group of the temperature conducting ports faces the center point of the heating cylinder.

[0017] A working method of a metal wear-resistant conveyor chain for refrigeration equipment, the working method comprising:

[0018] Start the chain to transport the objects to be frozen to the freezing equipment for freezing;

[0019] Start the chain, and convey the object to be frozen into the freezing equipment through the conveying component for freezing treatment;

[0020] After the freezing work is completed, this section of the chain leaves the cavity of the freezing equipment and penetrates into the cavity of the heating unit;

[0021] The heating unit works to heat up this section of the chain;

[0022] This section of the chain leaves the heating unit and enters the cavity of the internal vibration tube;

[0023] Start the vibration motor, drive each cleaning brush body through the vibration motor to remove the common metal debris on the surface of the chain, and use each vibration head to shake off the metal debris with strong adsorption;

[0024] After the cleaning work is completed, this section of the chain leaves the cavity of the internal vibration tube and continues to move. When this section of the chain runs to the starting point, it starts to convey the object to be frozen again.

[0025] The beneficial effects of the present invention are:

[0026] 1. Through the high-frequency vibration of each cleaning brush body, the common metal debris on the surface of the chain passing through the cavity of the internal vibration tube after heating is removed, and then the high-frequency vibration of each vibration head is used to shake off the metal debris with strong adsorption, thereby improving the cleaning effect. It not only protects the chain and avoids jamming caused by the accumulation of metal debris, but also can realize anti-oxidation and wear-resistant treatment without stopping the conveying chain, ensuring the continuity of the conveying work.

[0027] 2. When the chain passes through the heating cylinder, when the chain passes through the heating cylinder, the heat energy is transferred to the chain by the sliding fit of each heat conduction head and the chain. So that the chain can complete the heating work during operation. And the diameter at the center of the heating cylinder is larger than the inner diameter of the two ends, and the output ends of each heat conduction port are all directed towards the center point of the heating cylinder. Therefore, the time for heat energy to accumulate in the heating cylinder is extended, ensuring the constancy of the temperature. Thus, it can avoid the metal debris being frozen on the chain after the moisture condenses into ice due to too low temperature, improving the convenience of the cleaning work.

[0028] 3. When the pipe rack with the object to be frozen enters the freezing equipment, in addition to cooling the object to be frozen from the top, the outer horizontal pipe absorbs cold air and conducts it to the inner horizontal pipe, and then the inner horizontal pipe acts on the bottom of the object to be frozen from the bottom through micropores. And after the cold air sinks to the crescent groove, by using the characteristics of its fan-shaped ring structure, the cold air forms a reflux, and then the V-shaped through groove is used to make the reflux cold air act on the object to be frozen, making the freezing operation more three-dimensional. When metal debris on the chain accidentally falls on the rack block, it can also quickly fall through the V-shaped through groove without leaving, which not only improves the freezing effect but also ensures the quality of the object to be frozen.

[0029] 4. When the transportation component passes through the turning point of the chain, by using the hinge connection between the rack block and the main rotating shaft, the end of the rack block away from the main rotating shaft can rotate downward, which not only ensures the smooth transportation of the object to be frozen by the transportation component but also ensures the smooth operation of the chain. When the object to be frozen is placed on the top of the rack block, the upward-turning baffle prevents the rack block from rotating upward due to the load of heavy objects, thereby improving the bearing capacity of the rack block. While ensuring the smooth operation of the chain, it also improves the transportation stability and bearing capacity of the rack block.

[0030] Other features and advantages of the present invention will be described in the following specification, and in part, will become apparent from the specification or will be understood by implementing the present invention. The objectives and other advantages of the present invention can be achieved and obtained through the structures pointed out in the specification, claims, and drawings.

Detailed implementation manners

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] The embodiments of the present invention provide a metal wear-resistant conveying chain for a refrigeration device. Exemplarily, as Figure 1 shown, it includes a power component and two groups of parallel chains 100, and both groups of the chains 100 are in transmission connection with the power component.

[0044] A number of groups of transportation components 200 are arranged at equal intervals in the gap between the two groups of the chains 100. The transportation components 200 are used to place items to be refrigerated.

[0045] A chip collecting box 300 is arranged directly below the gap between the two groups of chains 100. Two groups of rust removing units 400 are symmetrically arranged at the edges on both sides of the top of the chip collecting box 300, and a heating unit 500 is arranged at one end of the rust removing unit 400. The rust removing unit 400 is used to remove the oxidized debris on the surface of the chain 100. The heating unit 500 is used to heat the chain 100 before rust removal.

[0046] Specifically, the two groups of chains 100 respectively pass through the cavities of a corresponding group of rust removing units 400 and heating units 500.

[0047] Specifically, a heating component is connected to the input end of the heating unit 500.

[0048] Exemplarily, as Figure 2 、 Figure 3 and Figure 4 shown, the transportation component 200 includes a horizontally arranged outer horizontal pipe 210. The two ends of the outer horizontal pipe 210 are respectively installed on the two groups of chains 100. An inner horizontal pipe 220 is arranged in the cavity of the outer horizontal pipe 210. Both the inner horizontal pipe 220 and the outer horizontal pipe 210 are made of heat-conducting materials. A pipe support 230 is sleeved on the outer wall of the outer horizontal pipe 210. A number of crescent grooves 231 are distributed in a circular array on the outer wall of the pipe support 230. The cross-section of the port of the crescent groove 231 is a fan-shaped ring structure. A number of micropores 240 are evenly distributed on the crescent groove 231. One end of the micropore 240 far from the opening is communicated with the cavity of the outer horizontal pipe 210.

[0049] Exemplarily, a total rotating shaft 250 is arranged between two adjacent groups of pipe supports 230. The two ends of the total rotating shaft 250 are respectively rotatably connected to the two groups of chains 100. An upward turning baffle 260 is arranged at the top of the total rotating shaft 250. A number of material supporting blocks 270 are arranged at equal intervals on both sides of the total rotating shaft 250. The material supporting blocks 270 are hinged to the total rotating shaft 250, and a V-shaped through groove 271 is opened at the center of the material supporting block 270. Both the upper and lower ends of the V-shaped through groove 271 are open structures, and the inner diameter of the top opening of the V-shaped through groove 271 is larger than the inner diameter of the bottom opening.

[0050] Place the object to be frozen on the racking block 270. When the chain 100 operates to convey the object to be frozen into the freezing equipment, in addition to cooling the object to be frozen from the top, the outer horizontal tube 210 absorbs cold air and conducts it to the inner horizontal tube 220, and then the inner horizontal tube 220 acts on the bottom of the object to be frozen from the bottom through the micropores 240. And after the cold air sinks to the crescent groove 231, due to the characteristics of its fan-shaped ring structure, the cold air forms a reflux, and then the V-shaped through groove 271 is used to make the reflux cold air act on the object to be frozen, making the freezing operation more three-dimensional. When metal debris on the chain 100 accidentally falls on the racking block 270, it can also quickly fall through the V-shaped through groove 271 without leaving any residue, which not only improves the freezing effect but also ensures the quality of the object to be frozen.

[0051] Exemplarily, as Figure 5 and Figure 6 shown, the rust removal unit 400 includes a motor bracket 410. One end of the motor bracket 410 close to the chain 100 is provided with an outer fixed tube 420. The outer fixed tube 420 is a horizontally arranged cylindrical structure. A first horizontal through groove is formed on a side wall of the outer fixed tube 420 away from the motor bracket 410. An inner shock tube 430 with a cylindrical structure is arranged at the center of the outer fixed tube 420. A reinforcing rod 450 is installed on the inner shock tube 430. A vibration motor 440 is drivingly connected to the input end of the reinforcing rod 450. The base of the vibration motor 440 is installed in the motor bracket 410. A second horizontal through groove is formed on a side wall of the inner shock tube 430 away from the reinforcing rod 450. A plurality of groups of cleaning mechanisms 460 are distributed in an annular array on the inner wall of the inner shock tube 430.

[0052] Preferably, a buffer member is provided in the gap between the outer wall of the inner shock tube 430 and the inner wall of the outer fixed tube 420.

[0053] Exemplarily, as Figure 7 shown, the cleaning mechanism 460 includes a brush body mounting strip 461. A cleaning brush body 462 is installed on a side wall of the brush body mounting strip 461 close to the central axis of the inner shock tube 430. A plurality of groups of shock rods 463 are equally spaced along the length direction of the cleaning brush body 462. A shock head 464 is provided at the top of the shock rod 463.

[0054] After the chain 100 passes through the heating unit 500 and is heated, it immediately enters the cavity of the inner vibration tube 430. The vibration motor 440 is started, and the inner vibration tube 430 and each group of cleaning mechanisms 460 are driven by the vibration motor 440 to perform high-frequency vibration. The cleaning brush bodies 462 distributed in an annular array and vibrating at high frequency simultaneously remove the metal debris on the surface of the chain 100 from all directions. And when the metal debris has strong adsorption, the metal debris is shaken off by the sliding fit of the vibration head 464 and the chain 100. During the operation of the chain 100, the anti-oxidation and wear-resistant treatment of the chain 100 can be realized without stopping the conveying chain, ensuring the continuity of the conveying work.

[0055] Exemplarily, as Figure 8 and Figure 9 shown, the heating unit 500 includes a heating cylinder 510, and the diameter at the center of the heating cylinder 510 is larger than the diameters of the two ends. A third transverse through groove 520 is formed in the outer wall of the heating cylinder 510 on the same side as the first transverse through groove. A plurality of groups of temperature guiding components 530 are distributed in an annular array on the inner wall of the heating cylinder 510. A plurality of groups of temperature guiding ports 540 are installed on the temperature guiding components 530. The output end of each group of temperature guiding ports 540 faces the center point of the heating cylinder 510.

[0056] Specifically, due to the moisture in the air and the fact that there will be some residual moisture on the surface of the object to be frozen before freezing, after these moisture is condensed into ice after being cooled by the freezing equipment, it is extremely easy to adsorb on the chain 100, and the metal debris also adsorbs on the chain 100, increasing the difficulty of the later cleaning work of the metal debris. Therefore, the chain 100 passing through the freezing equipment needs to be heated first to melt the ice on its surface.

[0057] First, the heat medium is transported to each group of temperature guiding components 530 through the heating component. When the chain 100 passes through the heating cylinder 510, the heat energy is transferred to the chain 100 by the sliding fit of each group of temperature guiding heads and the chain 100. So that the chain 100 can complete the heating work during the operation. And the diameter at the center of the heating cylinder 510 is larger than the inner diameters of the two ends, and the output ends of each group of temperature guiding ports 540 face the center point of the heating cylinder 510. Therefore, the time for the heat energy to accumulate in the heating cylinder 510 is extended, ensuring the constancy of the temperature. Thus, it can be avoided that after the moisture condenses into ice due to too low temperature, the metal debris is frozen on the chain 100.

[0058] The above embodiments have the following beneficial effects:

[0059] 1. By means of the high-frequency vibration of each cleaning brush body 462, the ordinary metal debris on the surface of the chain 100 passing through the cavity of the inner vibration tube 430 after heating is removed. Then, the metal debris with strong adsorption is shaken off by the high-frequency vibration of each vibration head 464, thereby improving the cleaning effect. This not only protects the chain 100 from jamming caused by the accumulation of metal debris, but also enables anti-oxidation and wear-resistant treatment without stopping the conveying chain, ensuring the continuity of the conveying work.

[0060] 2. When the chain 100 passes through the heating cylinder 510, heat energy is transferred to the chain 100 by the sliding fit of each heat conduction head and the chain 100. Thus, the chain 100 can complete the heating work during operation. Moreover, the diameter at the center of the heating cylinder 510 is larger than the inner diameters of the two ends, and the output ends of each heat conduction port 540 are all directed towards the center point of the heating cylinder 510. Therefore, the time for heat energy to accumulate in the heating cylinder 510 is extended, ensuring the constancy of the temperature. This can avoid the situation where moisture condenses into ice due to too low temperature and freezes the metal debris on the chain 100, improving the convenience of the cleaning work.

[0061] 3. When the pipe 230 with the object to be frozen placed on it enters the freezing equipment, in addition to cooling the object to be frozen from the top, the outer horizontal pipe 210 absorbs cold air and conducts it to the inner horizontal pipe 220, and then the inner horizontal pipe 220 acts on the bottom of the object to be frozen from the bottom through the micropores 240. And after the cold air sinks to the crescent groove 231, due to the characteristics of its fan-shaped structure, the cold air forms a reflux. Then, the reflux cold air acts on the object to be frozen through the V-shaped through groove 271, making the freezing operation more three-dimensional. When the metal debris on the chain 100 accidentally falls onto the racking block 270, it can also quickly fall through the V-shaped through groove 271 without leaving any residue, not only improving the freezing effect but also ensuring the quality of the object to be frozen.

[0062] 4. When the transportation component 200 passes through the turning point of the chain 100, by means of the hinge connection between the racking block 270 and the main rotating shaft 250, the end of the racking block 270 away from the main rotating shaft 250 can rotate downward, ensuring the smooth transportation of the object to be frozen by the transportation component 200 while also ensuring the smooth operation of the chain 100. When the object to be frozen is placed on the top of the racking block 270, the upward rotation of the racking block 270 due to the heavy load is avoided by the upward-turning baffle 260, and thereby the bearing capacity of the racking block 270 is improved. While ensuring the smooth operation of the chain 100, the transportation stability and bearing capacity of the racking block 270 are also improved.

[0063] Based on the above-mentioned metal wear-resistant conveying chain for a freezing equipment, the embodiment of the present invention further proposes a working method for this conveying chain. Exemplarily, the working method includes:

[0064] Start the chain, and convey the object to be frozen into the freezing equipment through the transportation component for freezing treatment;

[0065] After the freezing work is completed, this section of the chain leaves the cavity of the freezing equipment and penetrates into the cavity of the heating unit;

[0066] The heating unit works to heat up this section of the chain;

[0067] This section of the chain leaves the heating unit and enters the inner vibration tube cavity;

[0068] Start the vibration motor, drive each cleaning brush body through the vibration motor to remove the ordinary metal debris on the surface of the chain, and use each vibration head to shake off the metal debris with strong adsorption;

[0069] After the cleaning work is completed, this section of the chain leaves the inner vibration tube cavity and continues to move. When this section of the chain runs to the starting point, it starts to convey the object to be frozen again.

[0070] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
