Description

Technical Field

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

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

[0003] After searching, the patent document of a cooling conveyor with adjustable conveyor chain spacing, with publication number CN118833567A and publication date October 25, 2024, is cited. The patent document includes two limit side plates arranged on the inner side of the frame, which are installed on parallel linear guide rails, bidirectional screw rods and transmission shafts. The limit side plates are connected with 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 with the bidirectional screw rods by nuts. The relative position of the two limit side plates can be controlled by controlling the rotation and stop of the bidirectional screw rods. The transmission wheel installed on the limit side plate is connected with the transmission shaft by a sliding key structure. The transmission shaft can realize the sliding of the transmission wheel on the transmission shaft while transmitting torque to the transmission wheel.

Then, the vibration motor drives each group of cleaning mechanisms to vibrate at a high frequency to remove the oxidized waste from the chain surface.

[0006] 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.

[0007] 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.

[0008] 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.

[0009] 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.

[0010] 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.

[0012] 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.

[0013] 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.

[0014] A working method of a metal wear-resistant conveyor chain for refrigeration equipment, the working method comprising: Start the chain to transport the objects to be frozen to the freezing equipment for freezing; Start the chain and transport the objects to be frozen to the freezing equipment through the transport components for freezing treatment; After the freezing work is completed, the chain section leaves the cavity of the freezing equipment and passes through the cavity of the heating unit; The heating unit works to heat up the chain section; This section of chain leaves the heating unit and enters the inner seismic tube cavity; Start the vibration motor, and use the vibration motor to drive each group of cleaning brush bodies to remove ordinary metal debris on the chain surface, and use each group of vibration heads to shake off the metal debris with strong adsorption; After the cleaning work is completed, the chain section leaves the inner vibration tube cavity and continues to move. When the chain section runs to the starting point, the transmission work of the animals to be cooled is restarted.

[0015] The beneficial effects of the present invention are: 1. Through the high-frequency vibration of each set of cleaning brushes, the ordinary metal debris on the surface of the chain that has heated up and passed through the inner vibration tube cavity is removed, and then the high-frequency vibration of each set of vibration heads 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 achieves anti-oxidation and wear-resistant treatment without stopping the conveyor chain, ensuring the continuity of the conveying work.

[0016] 2. When the chain passes through the heating cylinder, the heat energy is transferred to the chain by sliding and fitting each group of temperature conducting heads with the chain. The chain can complete the heating work during operation. The diameter at the center of the heating cylinder is larger than the inner diameter of the openings at both ends, and the output ends of each group of temperature conducting ports are all facing the center point of the heating cylinder, thus extending the time for heat energy to gather in the heating cylinder and ensuring constant temperature. This can prevent the water from condensing into ice due to low temperature, freezing metal debris on the chain, and improving the convenience of cleaning work.

[0017] 3. When the rack tubes with the objects to be frozen enter the freezing equipment, in addition to cooling the objects to be frozen from the top, the outer horizontal tube absorbs the cold air and conducts it to the inner horizontal tube, which then acts on the bottom of the objects to be frozen from the bottom through the micropores. After the cold air sinks to the crescent groove, the characteristics of its fan-shaped ring structure are used to make the cold air reflux, and then the V-shaped groove is used to make the refluxed cold air act on the objects 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 fall quickly through the V-shaped groove without being left behind, which not only improves the freezing effect, but also ensures the quality of the animals to be frozen.

[0018] 4. When the transport parts pass through the turning point of the chain, the hinge between the rack block and the main shaft is used to allow the end of the rack block away from the main shaft to rotate downward, ensuring that the transport parts can smoothly transport the frozen objects while ensuring the smooth operation of the chain. When the objects to be frozen are placed on the top of the rack block, the upward baffle prevents the rack block from rotating upward due to carrying 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.

[0019] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The embodiment of the present invention provides a metal wear-resistant conveyor chain for refrigeration equipment, for example, Figure 1 As shown, it includes a power component and two groups of chains 100 arranged in parallel, and the two groups of chains 100 are both drivingly connected to the power component.

[0033] Several groups of transport components 200 are arranged at equal intervals in the gap between the two groups of chains 100. The transport components 200 are used to place the products to be frozen.

[0034] A chip collecting box 300 is arranged just below the gap between the two groups of chains 100, and two groups of rust removal units 400 are symmetrically arranged at the edges of both sides of the top of the chip collecting box 300, and a heating unit 500 is arranged at one end of the rust removal unit 400. The rust removal 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.

[0035] Specifically, the two groups of chains 100 pass through the cavities of a corresponding group of rust removal units 400 and heating units 500 , respectively.

[0036] Specifically, the input end of the temperature increasing unit 500 is connected to a heating component.

[0037] For example, Figure 2 , Figure 3 and Figure 4 As shown, the transport component 200 includes a horizontally arranged outer transverse tube 210, the two ends of which are respectively mounted on two groups of chains 100, and an inner transverse tube 220 is arranged in the cavity of the outer transverse tube 210, and both the inner transverse tube 220 and the outer transverse tube 210 are made of heat-conducting material. A frame tube 230 is sleeved on the outer wall of the outer transverse tube 210, and a plurality of groups of crescent grooves 231 are distributed in an annular array on the outer wall of the frame tube 230, and the port cross section of the crescent groove 231 is a fan-shaped structure, and a plurality of groups of micropores 240 are evenly distributed on the crescent groove 231, and the end of the micropore 240 away from the opening is connected to the cavity of the outer transverse tube 210.

[0038] Exemplarily, a main rotating shaft 250 is provided between two adjacent groups of the frame tubes 230, and the two ends of the main rotating shaft 250 are respectively rotatably connected to the two groups of chains 100, and an upward baffle 260 is provided on the top of the main rotating shaft 250. A plurality of groups of frame blocks 270 are evenly spaced and arranged on both sides of the main rotating shaft 250. The frame blocks 270 are hinged to the main rotating shaft 250, and a V-shaped through groove 271 is provided at the center of the frame blocks 270. The upper and lower ends of the V-shaped through groove 271 are both 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.

[0039] The object to be frozen is placed on the rack block 270. When the chain 100 works to transport the object to be frozen into the freezing equipment, in addition to cooling the object to be frozen from the top, the outer transverse tube 210 absorbs cold air and conducts it to the inner transverse tube 220, and then the inner transverse tube 220 acts on the bottom of the object to be frozen from the bottom through the micropores 240. After the cold air sinks to the crescent groove 231, the characteristics of its fan-shaped ring structure are used to make the cold air reflux, and then the V-shaped through groove 271 is used to make the refluxed cold air act on the object to be frozen, making the freezing operation more three-dimensional. When the metal debris on the chain 100 accidentally falls on the rack block 270, it can also fall quickly through the V-shaped through groove 271 without being left behind, which not only improves the freezing effect but also ensures the quality of the animal to be frozen.

[0040] For example, Figure 5 and Figure 6As shown, the rust removal unit 400 includes a motor bracket 410. An outer fixed tube 420 is installed at one end of the motor bracket 410 close to the chain 100. The outer fixed tube 420 is a horizontally arranged cylindrical structure, and a first transverse groove is provided on a side wall of the outer fixed tube 420 away from the motor bracket 410. An inner vibration tube 430 of a cylindrical structure is provided at the center of the outer fixed tube 420, and a reinforcement rod 450 is installed on the inner vibration tube 430. A vibration motor 440 is transmission-connected to the input end of the reinforcement rod 450, and the base of the vibration motor 440 is installed in the motor bracket 410. A second transverse groove is provided on a side wall of the inner vibration tube 430 away from the reinforcement rod 450. A plurality of cleaning mechanisms 460 are distributed in a circular array on the inner wall of the inner vibration tube 430.

[0041] Preferably, a buffer component is provided in the gap between the outer wall of the inner seismic tube 430 and the inner wall of the outer fixed tube 420 .

[0042] For example, Figure 7 As shown, the cleaning mechanism 460 includes a brush body mounting strip 461, and a cleaning brush body 462 is mounted on a side wall of the brush body mounting strip 461 close to the central axis of the inner vibration tube 430. A plurality of groups of vibration rods 463 are evenly spaced in the cleaning brush body 462 along its own length direction, and a vibration head 464 is provided on the top of the vibration rod 463.

[0043] After the chain 100 passes through the heating unit 500 and is heated, it immediately enters the cavity of the inner vibration tube 430, starts the vibration motor 440, drives the inner vibration tube 430 and each group of cleaning mechanisms 460 to vibrate at high frequency through the vibration motor 440, and uses each group of cleaning brush bodies 462 distributed in a circular array and vibrating at high frequency to remove metal debris on the surface of the chain 100 from all directions at the same time. And when the metal debris has strong adsorption, the metal debris is shaken off by the sliding fit between the vibration head 464 and the chain 100, and the anti-oxidation and wear-resistant treatment of the chain 100 can be achieved during the operation of the chain 100, without stopping the conveyor chain, ensuring the continuity of the conveying work.

[0044] For example, Figure 8 and Fig. 9 As 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 diameter of the openings at both ends. A third transverse groove 520 is provided on the outer wall of the heating cylinder 510 on the same side as the first transverse groove, and a plurality of groups of temperature conducting components 530 are distributed in a circular array on the inner wall of the heating cylinder 510. A plurality of groups of temperature conducting ports 540 are installed on the temperature conducting components 530. The output end of each group of the temperature conducting ports 540 faces the center point of the heating cylinder 510.

[0045] Specifically, due to the moisture in the air and some moisture remaining on the surface of the frozen object before freezing, this moisture condenses into ice after being cooled by the refrigeration equipment, and is easily adsorbed on the chain 100, causing metal debris to be also adsorbed on the chain 100, increasing the difficulty of cleaning the metal debris later. Therefore, the chain 100 that has passed through the refrigeration equipment needs to be heated up first to melt the ice on its surface.

[0046] First, the heat medium is transported to each group of temperature conducting 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 sliding and fitting each group of temperature conducting heads with the chain 100. The chain 100 can complete the heating work during operation. In addition, the diameter at the center of the heating cylinder 510 is larger than the inner diameter of the openings at both ends, and the output ends of each group of temperature conducting ports 540 are all facing the center point of the heating cylinder 510, thereby extending the time for heat energy to gather in the heating cylinder 510 and ensuring constant temperature. This can prevent the metal debris from freezing on the chain 100 after the water condenses into ice due to too low a temperature.

[0047] The above embodiments have the following beneficial effects: 1. Through the high-frequency vibration of each group of cleaning brush bodies 462, ordinary metal debris on the surface of the chain 100 that has heated up and passed through the cavity of the inner vibration tube 430 is removed, and then the metal debris with strong adsorption is shaken off by the high-frequency vibration of each group of vibration heads 464, thereby improving the cleaning effect. It not only protects the chain 100 and avoids jamming caused by accumulation of metal debris, but also realizes anti-oxidation and wear-resistant treatment without stopping the conveying chain, thereby ensuring the continuity of the conveying work.

[0048] 2. When the chain 100 passes through the heating cylinder 510, the heat energy is transferred to the chain 100 by sliding and fitting each group of temperature conducting heads with the chain 100. The chain 100 can complete the heating work during operation. In addition, the diameter at the center of the heating cylinder 510 is larger than the inner diameter of the openings at both ends, and the output ends of each group of temperature conducting ports 540 are all facing the center point of the heating cylinder 510, thereby extending the time for heat energy to gather in the heating cylinder 510 and ensuring the constant temperature. This can prevent the metal debris from freezing on the chain 100 after the water condenses into ice due to the low temperature, thereby improving the convenience of cleaning work.

[0049] 3. When the rack tube 230 with the object to be frozen is placed into the freezing equipment, in addition to cooling the object to be frozen from the top, the outer transverse tube 210 absorbs cold air and conducts it to the inner transverse tube 220, and then the inner transverse tube 220 acts on the bottom of the object to be frozen from the bottom through the micropores 240. After the cold air sinks to the crescent groove 231, the characteristics of its fan-shaped ring structure are used to make the cold air reflux, and then the V-shaped through groove 271 is used to make the refluxed cold air act on the object to be frozen, making the freezing operation more three-dimensional. When the metal debris on the chain 100 accidentally falls on the rack block 270, it can also fall quickly through the V-shaped through groove 271 without being left behind, which not only improves the freezing effect, but also ensures the quality of the animal to be frozen.

[0050] 4. When the transport component 200 passes through the turning point of the chain 100, the hinged connection between the rack block 270 and the main rotating shaft 250 allows the end of the rack block 270 away from the main rotating shaft 250 to rotate downward, ensuring that the transport component 200 can smoothly transport the frozen objects while ensuring the smooth operation of the chain 100. When the frozen objects are placed on the top of the rack block 270, the upward baffle 260 prevents the rack block 270 from rotating upward due to carrying heavy objects, thereby improving the bearing capacity of the rack block 270. While ensuring the smooth operation of the chain 100, the transportation stability and bearing capacity of the rack block 270 are also improved.

[0051] Based on the above-mentioned metal wear-resistant conveyor chain for refrigeration equipment, an embodiment of the present invention further proposes a working method of the conveyor chain. Exemplarily, the working method includes: Start the chain and transport the objects to be frozen to the freezing equipment through the transport components for freezing treatment; After the freezing work is completed, the chain section leaves the cavity of the freezing equipment and passes through the cavity of the heating unit; The heating unit works to heat up the chain section; This section of chain leaves the heating unit and enters the inner seismic tube cavity; Start the vibration motor, and use the vibration motor to drive each group of cleaning brush bodies to remove ordinary metal debris on the chain surface, and use each group of vibration heads to shake off the metal debris with strong adsorption; After the cleaning work is completed, the chain section leaves the inner vibration tube cavity and continues to move. When the chain section runs to the starting point, the transmission work of the animals to be cooled is restarted.

[0052] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions 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.
