Description

Technical Field

[0001] This invention relates to the field of supply chain transshipment technology, specifically to a supply chain transshipment device. Background Technology

[0002] The modern food supply chain system is centered on cold chain logistics, running through the entire process of raw material procurement, production and processing, warehousing and transportation, and terminal sales. Its core lies in achieving efficient coordination between food quality and safety. Frozen food, as an important category in the supply chain, requires material flow to be completed in a continuously low-temperature environment during its transportation. It is necessary to ensure that the core temperature of the product is strictly maintained below -18°C, while also meeting the requirements of large-scale production for operational efficiency and hygiene standards. In low-temperature, high-humidity, and space-constrained operating scenarios, traditional manual handling methods are prone to temperature fluctuations and physical damage, while intermittent transportation equipment is difficult to achieve continuous operation. Therefore, chain conveyors with stable transmission rates have become an essential device in the food transportation process.

[0003] When frozen food conveyors operate in low-temperature and high-humidity environments, the surface temperature of the conveyor chain plates is lower than the ambient dew point temperature, causing moisture in the air to condense and freeze, forming a frost layer. This frost layer creates an ice film on the contact surface between the chain plates and the frozen food, significantly reducing the coefficient of friction and thus lowering transmission efficiency. Therefore, continuous defrosting of the conveyor chain plate surface is necessary during the conveying process. In existing technologies, mechanical scrapers and hot air defrosting have become the main defrosting methods due to their simple structure, low modification difficulty, and controllable short-term costs. However, mechanical scrapers rely on physical contact de-icing, and the continuous scraping action accelerates the wear of the chain plate substrate surface. Insufficient contact between the blade and the belt surface also results in localized ice residue. Hot air defrosting forcibly melts the ice layer through high-temperature airflow, but the heat conduction process disrupts the uniformity of the cold chain temperature field and has low energy utilization. At the same time, the melted condensate quickly regenerates into frost in the low-temperature environment, forming a vicious cycle of "defrosting-frost formation." To address this, we propose a supply chain transfer device. Summary of the Invention

[0004] One of the technical problems this application aims to solve is that mechanical scrapers rely on physical contact for de-icing, and the continuous scraping action leads to accelerated wear on the surface of the conveyor belt substrate. Furthermore, insufficient contact between the blade and the belt surface results in localized ice residue. Hot air defrosting, on the other hand, forcibly melts the ice layer through high-temperature airflow, but the heat conduction process disrupts the uniformity of the cold chain temperature field and has low energy utilization.

[0010] In some embodiments, the collection unit includes a squeezing member disposed in the defrosting chamber, which squeezes the absorbent cotton after it has absorbed water. A collection member is disposed in the defrosting chamber to collect the squeezed water.

[0011] In some embodiments, the extrusion member includes an extrusion chamber disposed on a mounting frame, an extrusion plate slidably disposed in the extrusion chamber, a plurality of extrusion springs disposed in the extrusion chamber, one end of each extrusion spring being connected to the extrusion plate, a pressure block disposed on the extrusion plate, the pressure block abutting against the absorbent cotton, and the pressure block being a triangular block.

[0012] In some embodiments, the collecting component includes a collecting chamber disposed within a defrosting chamber, the collecting chamber having a plurality of liquid collection slots corresponding to the pressure block, and the mounting frame having a guide plate for use in conjunction with the pressure block and the liquid collection slots.

[0013] In some embodiments, the support plate has a groove, a slider is slidably disposed in the groove, a pressure spring is disposed in the groove, one end of the pressure spring is connected to the slider, a sensing plate is disposed on the slider, the sensing plate is slidably connected to the support plate, a plurality of lifting grooves are provided on the sensing plate, a wedge block is slidably disposed in the lifting groove, a telescopic rod three is slidably disposed on the support plate at the position of the lifting groove, the telescopic rod three is connected to the wedge block, a return spring one is disposed on the telescopic rod three, and a push block that cooperates with the wedge block is disposed on the support plate at the position of the lifting groove.

[0014] In some embodiments, a cooling chamber is provided on the defrosting chamber, and the cooling chamber is connected to the defrosting chamber.

[0015] This invention has at least the following beneficial effects:

[0016] 1. The defrosting unit utilizes a design that drives the heating element to rotate the absorbent cotton around an axis. This allows the heated absorbent cotton to dynamically and tightly adhere to the surface of the support plate. This flexible contact mode avoids the equipment wear that can be caused by metal scraper defrosting and achieves rapid melting and absorption of frost through the dual effects of heat conduction and physical adsorption, significantly improving thermal efficiency compared to static heating defrosting. The collection unit design solves the problem of liquid water handling during the defrosting process. Through a combination of centrifugal separation and diversion collection, the melted water absorbed by the absorbent cotton is promptly removed from the working area. This prevents the water from re-condensing and forming a secondary ice layer at low temperatures. The continuous working mode of the rotating absorbent cotton also creates a uniform heat field distribution, avoiding local overheating or defrosting dead zones, ensuring the thoroughness and consistency of frost removal from the support plate surface, and providing a stable and uncontaminated bearing interface for frozen foods. The separate defrosting mechanism significantly reduces the energy consumption of traditional overall heating defrosting. The heating element only needs to heat the absorbent cotton, without affecting the low-temperature transportation of frozen foods, and the heat storage characteristics of the absorbent cotton can extend the heat retention time.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1-10This invention provides a technical solution: a supply chain transfer device, including a support 1, a conveyor body 2, and a chain plate 3. A support plate 4 that contacts frozen food is installed on the chain plate 3. A defrost chamber 5 is provided on the conveyor body 2. The defrost chamber 5 contains multiple heating tubes 6 arranged parallel to each other along the length of the defrost chamber 5, and each heating tube 6 has an absorbent cotton 7 fitted on its outer surface. A defrost unit 8, connected to the heating tubes 6 and the absorbent cotton 7, is provided inside the defrost chamber 5. This unit drives the heating tubes 6 to rotate the absorbent cotton 7 around its axis after the frosted support plate 4 moves into the defrost chamber 5, causing the heated absorbent cotton 7 to contact the surface of the support plate 4 and remove the frost. A collection unit 12 is provided inside the defrost chamber 5 to separate and collect the water absorbed by the absorbent cotton 7.

[0034] The defrosting unit 8 includes an unfolding component 9 mounted on the chain plate 3, which controls the movement of the support plate 4. The unfolding component 9 is equipped with a driving component 10, which drives the unfolding component 9 to work. The defrosting chamber 5 is equipped with a melting component 11, which drives the heating tube 6 to rotate the absorbent cotton 7 around its axis.

[0035] The unfolding component 9 includes a power groove 91 disposed within the chain plate 3. Multiple rotating rods 92 are rotatably disposed within the power groove 91. A push screw 93 is disposed on each rotating rod 92. The push screw 93 is threadedly connected to the rotating rod 92. One end of the push screw 93 is connected to the support plate 4.

[0036] The driving component 10 includes a driving worm gear 101 mounted on a rotating rod 92. A driving worm 102, which meshes with the driving worm gear 101, is rotatably mounted in the power groove 91. One end of the driving worm 102 passes through the power groove 91. A driving gear 103 is mounted on a section of the driving worm 102 outside the power groove 91. Two driving racks 104, which mesh with the driving gears 103, are mounted on the main body 2 of the conveying device. The two driving racks 104 are located at both ends of the defrosting chamber 5 and on both sides of the driving gear 103.

[0037] When the conveyor body 2 is working, it will drive the chain plate 3 to move in a cycle. During the movement of the chain plate 3, it will drive the support plate 4 set on it to move synchronously to convey frozen food. When the chain plate 3 drives the support plate 4 to move below the conveyor, the drive gear 103 on the support plate 4 meshes with the first drive rack 104 and rotates under the push of the drive rack 104. The rotation of the drive gear 103 drives the drive worm 102 to rotate. The rotation of the drive worm 102 drives the drive worm wheel 101 to rotate. The rotation of the drive worm wheel 101 drives the push screw threaded to it to move the support plate 4, so that the support plate 4 moves away from the chain plate 3 and then enters the defrost chamber 5 during continuous movement.

[0038] Through the mechanical linkage mechanism of worm gear and rack and pinion transmission, the support plate 4 can be precisely triggered to disengage when the chain plate 3 is conveyed to the predetermined station of the defrosting chamber 5. This physical separation allows the defrosting chamber 5 to independently oriented the support plate 4, avoiding the problem of interruption in the transportation process when defrosting the traditional integral chain plate 3. This ensures the continuity of frozen food transportation and ensures that the defrosting operation is completed in a closed environment. The separate structural design strictly limits the heat effect area of ​​the support plate 4 during defrosting to the defrosting chamber 5, reducing the ineffective diffusion of heat energy to other parts of the chain plate 3. This improves the heat energy utilization rate and avoids structural fatigue of the chain plate 3 material due to repeated thermal expansion and contraction. In addition, the separability of the support plate 4 and the chain plate 3 provides convenience for modular maintenance. Damaged or cleaning support plates 4 can be disassembled and processed separately without stopping the entire conveyor line for maintenance, which greatly improves the overall utilization rate and maintenance efficiency of the equipment.

[0039] The melting component 11 includes multiple mounting brackets 111 disposed within the defrosting chamber 5. The heating tubes 6 pass through the mounting brackets 111, the defrosting chamber 5, and the conveying device body 2 at both ends, and are rotatably connected to the mounting brackets 111, the defrosting chamber 5, and the conveying device body 2. A synchronous gear 112 is provided at one end of the multiple heating tubes 6 outside the defrosting chamber 5. A synchronous toothed belt 113 is fitted on the synchronous gear 112. Multiple limiting rods 114 are provided on both sides of the synchronous toothed belt 113 on the conveying device body 2. A rotating shaft 115 is provided on the power output shaft of the conveying device body 2. A rotating pulley 116 is provided on the rotating shaft 115 and the heating tubes 6. A rotating belt 117 is provided on the rotating pulley 116. A hot air pump 118 is provided outside the defrosting chamber 5, and the hot air pump 118 is rotatably connected to the heating tubes 6.

[0040] After the support plate 4 enters the defrosting chamber 5, it first comes into contact with the absorbent cotton 7 on the heating tube 6. Since the absorbent cotton 7 is fitted onto the heating tube 6, the heated absorbent cotton 7 will adhere tightly to the surface of the support plate 4 to melt the frost on the surface of the support plate 4. At the same time that the absorbent cotton 7 adheres to the support plate 4, the rotating shaft 115 rotates and drives the heating tube 6 to rotate synchronously through the rotating pulley 116 and the rotating belt 117. The rotation of a single heating tube 6 drives the synchronous gear 112 to rotate, and drives multiple heating tubes 6 to rotate synchronously through the synchronous toothed belt 113. The rotation of the heating tube 6 drives the absorbent cotton 7 to rotate synchronously, so that the heated area of ​​the absorbent cotton 7 is always in contact with the frost on the support plate 4 and absorbs the water after the frost melts.

[0041] After the support plate 4 detaches from the chain plate 3 and enters the defrosting chamber 5, the rotating shaft 115 drives the heating tubes 6 to rotate synchronously via the rotating belt 117. This, combined with the linkage mechanism of the synchronous gear 112 and the synchronous toothed belt 113, ensures that multiple heating tubes 6 drive the absorbent cotton 7 to rotate at the same angular velocity, allowing different areas of the heated absorbent cotton 7 to circulate and contact the surface of the support plate 4, ensuring uniform melting of the frost. The rotating connection design between the hot air pump 118 and the heating tubes 6 synchronously injects hot air during mechanical rotation, forming a dual effect of heat conduction and convection heat transfer, accelerating the melting of the frost layer. While improving efficiency, it also avoids carbonization damage to the absorbent cotton 7 caused by excessively high local temperatures. The continuous working mode of the rotating absorbent cotton 7 can also form a uniform heat field distribution, avoiding local overheating or defrosting dead zones, ensuring the thoroughness and consistency of frost removal on the surface of the support plate 4, and providing a stable and uncontaminated bearing interface for frozen foods. The separate defrosting mechanism significantly reduces the energy consumption of traditional whole-body heating defrosting. The heating tube 6 only needs to heat the absorbent cotton 7 specifically, which will not affect the low-temperature transportation of frozen foods, and the heat storage characteristics of the absorbent cotton 7 can extend the heat maintenance time.

[0042] The collection unit 12 includes a squeezing member 13 disposed in the defrosting chamber 5, which squeezes the absorbent cotton 7 after it has absorbed water. The defrosting chamber 5 is provided with a collection member 14, which collects the squeezed water.

[0043] The extrusion component 13 includes an extrusion chamber 131 mounted on a mounting frame 111. An extrusion plate 132 is slidably disposed inside the extrusion chamber 131. A plurality of extrusion springs 133 are disposed inside the extrusion chamber 131. One end of each extrusion spring 133 is connected to the extrusion plate 132. A pressure block 134 is disposed on the extrusion plate 132. The pressure block 134 abuts against the absorbent cotton 7 and is a triangular block.

[0044] The collection component 14 includes a collection chamber 141 disposed in the defrost chamber 5. The collection chamber 141 has a plurality of liquid collection slots 142 corresponding to the pressure block 134. The mounting frame 111 is provided with a guide plate 143 that works in conjunction with the pressure block 134 and the liquid collection slots 142.

[0045] When the heating tube 6 drives the absorbent cotton 7 to rotate, it comes into contact with the pressure block 134 located on the mounting bracket 111. At the same time, since a compression spring 133 is provided between the pressure block 134 and the compression chamber 131, the pressure block 134 will squeeze the absorbent cotton 7, so that the water absorbed by the absorbent cotton 7 is squeezed out and flows into the guide plate 143 through the triangular edge of the pressure block 134. Finally, it enters the collection chamber 141 through the guide plate 143 and the liquid collection groove 142.

[0046] The triangular pressure block 134 utilizes its inclined surface to form a progressive squeezing contact with the rotating trajectory of the absorbent cotton 7. Under the elastic support of the squeezing spring 133, dynamic pressure adjustment is achieved. This automatically adapts the squeezing force to changes in the thickness of the absorbent cotton 7, and the edge guides the squeezed water precisely to the collection tank, effectively avoiding water splashing caused by traditional tapping-type dehydration. The physical isolation design between the separate squeezing chamber 131 and the conveyor chain 3 ensures that the drainage operation is completed entirely in a sealed space, preventing water vapor from seeping back to the hinge of the chain 3 during squeezing and causing moisture buildup. The mechanism eliminates slippage and prevents drainage vibration from interfering with the stability of the conveying process; the elastic buffering characteristics of the compression spring 133 can avoid damage to the fiber structure of the absorbent cotton 7 by rigid compression, while the symmetrical structure of the triangular pressure block 134 can maintain a stable drainage path under bidirectional rotation conditions; the combination of the modular liquid collection tank and the guide plate 143 allows liquid water to quickly leave the working area, fundamentally eliminating the hidden danger of secondary freezing of accumulated water; the synchronous operation of this mechanism with the rotary heating system can also remove saturated moisture from the absorbent cotton 7 in real time during continuous defrosting, maintaining its optimal absorbency.

[0047] Example 2: Please refer to Figures 11-12 The present invention provides a technical solution: a slide groove 15 is provided on a support plate 4, a slider 151 is slidably disposed in the slide groove 15, a pressure spring 152 is disposed in the slide groove 15, one end of the pressure spring 152 is connected to the slider 151, a sensing plate 153 is disposed on the slider 151, the sensing plate 153 is slidably connected to the support plate 4, a plurality of lifting grooves 154 are provided on the sensing plate 153, a wedge block 155 is slidably disposed in the lifting groove 154, a telescopic rod 156 is slidably disposed on the support plate 4 at the position of the lifting groove 154, the telescopic rod 156 is connected to the wedge block 155, a return spring 157 is disposed on the telescopic rod 156, and a push block 158 is disposed on the support plate 4 at the position of the lifting groove 154 to cooperate with the wedge block 155.

[0048] When the support plate 4 freezes rapidly due to external environmental factors, causing the frozen food to stop during the conveying process of the chain plate 3, the friction between the sensing plate 153 and the frozen food decreases as the frozen food stops moving. This causes the sensing plate 153 to move under the push of the pressure spring 152. The movement of the sensing plate 153 drives the wedge block 155 to move. During the movement of the wedge block 155, it comes into contact with the push block 158 and rises under the push of the push block 158, forming a protrusion. This protrusion pushes the frozen food, allowing it to start moving again. The rising of the wedge block 155 can also break the ice on the surface of the sensing plate 153.

[0049] When the frozen food on the support plate 4 stops sliding due to the thickening of the ice layer, the friction between the sensing plate 153 and the food decreases sharply, triggering the release of the pressure spring 152. This pushes the slider 151, causing the sensing plate 153 to move laterally. The wedge block 155 in the linkage lifting groove 154 rises along the inclined surface of the push block 158 to form a protruding structure. This protrusion not only generates a directional pushing force to release the stuck food from stickiness, but also breaks the ice layer on the surface of the sensing plate 153 through the sharp edge of the wedge block 155. The adaptive pushing design can automatically adjust the lifting height of the wedge block 155 according to the resistance of the food stopping, avoiding food damage caused by rigid pushing. The distributed layout of the multiple lifting grooves 154 ensures that food of different sizes can be effectively triggered. The reset spring 157 causes the telescopic rod 156 to automatically retract after the stopping state is released, ensuring that the conveying surface is restored to flatness.

[0050] Example 3: Please refer to Figures 13-14 The present invention provides a technical solution: a cooling chamber 16 is provided on a defrosting chamber 5, the cooling chamber 16 is connected to the defrosting chamber 5, a sliding plate 161 is slidably arranged in the cooling chamber 16, a receiving groove 162 is opened on the sliding plate 161, a push plate 164 is slidably arranged in the receiving groove 162, a telescopic rod 163 is provided in the receiving groove 162, one end of the telescopic rod 163 is connected to the push plate 164, a buffer spring 165 is sleeved on the telescopic rod 163, a second telescopic rod 166 is provided in the cooling chamber 16, one end of the second telescopic rod 166 is connected to the sliding plate 161, a second return spring 167 is sleeved on the telescopic rod 166, and filter plates 168 are provided on both sides of the cooling chamber 16.

[0051] Because there are gaps between the support plates 4, when the support plates 4 enter the cooling chamber 16, the push plate 164 will enter the gap between the support plates 4 under the push of the buffer spring 165, and move under the drive of the support plates 4. When the push plate 164 moves to the maximum distance of the telescopic rod 166, the push plate 164 is subjected to the pressure of the support plates 4, thereby overcoming the elastic force of the buffer spring 165 and retracting, so that the push plate 164 is separated from the gap. After separation, the sliding plate 161 and the push plate 164 will quickly reset under the drive of the reset spring 167, so that a negative pressure is formed in the cooling chamber 16. Cold air is drawn in from the outside through the filter plate 168 to cool the support plates 4 that have been heated and defrosted. The function of the filter plate 168 is to prevent impurities from being sucked in.

[0052] When the defrosted support plate 4 enters the cooling chamber 16, the push plate 164 automatically embeds into the gap between the plates and moves along with it under the action of the buffer spring 165. When the displacement of the push plate 164 reaches the limit of the telescopic rod 166, the continuous movement of the support plate 4 forces the push plate 164 to overcome the spring pressure and retract. At this time, the sliding plate 161 is instantly reset under the strong traction of the reset spring 167. The sudden change in the volume of the chamber creates a controllable negative pressure, and clean cold air is drawn in through the filter plate 168 to quickly and evenly cool the high-temperature support plate 4, avoiding deformation of metal parts due to sudden cooling. The filter plate 168 has a dual function: it filters particulate matter in the air to prevent secondary pollution and forms a laminar flow cooling environment through airflow organization.
