Description

Technical Field

[0001] This utility model relates to the field of latex product manufacturing technology, specifically a latex freezer. Background Technology

[0002] The Talalay process is a process used to produce latex pillows. First, natural rubber latex is mixed with necessary additives. The mixed latex is then poured into a specially designed mold, but only partially filled. The mold is sealed and vacuumed, causing the latex to expand and distribute evenly. This step helps eliminate air bubbles in the latex, ensuring its uniformity. The latex in the mold is then frozen to approximately -30°C. This step helps the latex foam solidify, forming a consistent cellular structure. Carbon dioxide gas is injected into the frozen latex to help the foam "solidify" or "gel." The mold is then heated to approximately 110°C to vulcanize the latex foam, giving the product its normal resilience. Finally, the vulcanized latex pillow is removed from the mold, cleaned to remove residual soap and other impurities, and then dried.

[0003] The freezing step involves placing a sealed mold containing latex into a freezer for freezing. Currently, most freezing equipment places the cold source on one side of the equipment, freezing by continuously absorbing heat from the internal space. However, this arrangement of the cold source inevitably leads to lower temperatures closer to the cold source inside the equipment, resulting in uneven distribution of the low-temperature environment, which in turn affects the quality of the finished latex pillow. There is still room for optimization in the arrangement of the cold source in the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a latex freezer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A material conveying structure, which is movably installed at the bottom of the freezer compartment;

[0009] The control door structure consists of two sets, which are fixedly installed on both sides of the freezer compartment.

[0010] The refrigeration system includes a compressor refrigeration unit. The compressor refrigeration unit's air inlet is connected to an air supply pipe. One end of the air supply pipe is connected to two air supply branch pipes. One end of the air supply branch pipe is connected to a primary capillary tube. The other end of the primary capillary tube is connected to a first cooling coil. One end of the first cooling coil is connected to a secondary capillary tube. One end of the secondary capillary tube is connected to a second cooling coil. The secondary capillary tube and the second cooling coil are embedded inside the wall of the freezer compartment. The lower ends of the two second cooling coils are connected to a return air pipe. The return air pipe is connected to the compressor refrigeration unit's return air inlet.

[0011] Furthermore, the main body of the device also includes:

[0012] Sealing slots are provided at the openings on the front and rear sides of the freezer compartment;

[0013] An air inlet is provided, which is interspersed on the upper side of the freezer compartment, and the No. 1 cooling coil is embedded in the inner wall of the air inlet.

[0014] Fan No. 1 is fixedly installed at the opening of the air inlet;

[0015] Fan No. 2, which is fixedly installed on the bottom side of the freezer compartment;

[0016] Support legs are fixedly installed at the four corners of the bottom side of the freezer compartment.

[0017] Furthermore, the material conveying structure also includes:

[0018] A door is sealed, with one side of the door hinged to the lower edge of the sealing groove;

[0019] Compensating grooves are provided on both sides of the sealing door;

[0020] Conveyor belt number one, which is embedded in the upper surface of the sealing gate;

[0021] Motor No. 1 is fixedly installed on one side edge of the bottom of the sealing gate. The output end of Motor No. 1 is linked to one end of the bottom drive roller of conveyor belt No. 1 through gears.

[0022] Conveyor belt number two, which is embedded in the bottom of the freezer compartment;

[0023] The second motor is embedded at the bottom of the freezing chamber, and its output end is fixedly connected to one end of the drive roller inside the second conveyor belt.

[0024] Furthermore, the material conveying structure also includes:

[0025] The hinge unit, both conveyor belt No. 1 and conveyor belt No. 2 are composed of several hinge units that are hinged together end to end;

[0026] A magnetic strip, which is embedded in the middle of the hinge unit;

[0027] A mold support plate, wherein a mold is snapped onto the upper surface of the mold support plate, and a metal base plate is fixedly installed at the bottom of the mold support plate, and the bottom side of the metal base plate is attracted to a magnetic strip.

[0028] Furthermore, the gate control structure includes:

[0029] Motor No. 3 is embedded in the middle of both sides of the freezer compartment;

[0030] The gear is fixedly installed at the output end of motor number three.

[0031] Rack, the gear has racks meshing on both its upper and lower sides;

[0032] A limiting sleeve is fixedly installed on the side surface of the freezer compartment, and the rack passes through the limiting sleeve.

[0033] Furthermore, the control gate structure also includes:

[0034] A lifting rod is hinged to one end of the limiting sleeve;

[0035] A sliding column, one end of which is hinged to the lifting rod, and the other end of which is slidably engaged with a compensating sliding groove.

[0036] Compared with the prior art, the beneficial effects of this utility model are:

[0037] 1. The refrigerant delivery path is optimized into two branches, which are respectively arranged on both sides of the freezer compartment. This ensures that the cold environment inside the freezer compartment is evenly distributed and improves the freezing effect. At the same time, the refrigerant passes through the first-stage capillary tube and the second-stage capillary tube in sequence, ensuring that the refrigerant evaporates more completely and can absorb a large amount of heat. The cooling effect is improved through the pipeline structure itself.

[0038] 2. Before sealing the front and rear slots of the freezer compartment, when the refrigeration system is working, the freezer compartment is open at both ends, allowing the cold air inside to dissipate automatically. At the same time, the No. 1 fan is activated, blowing the air cooled by the first-stage capillary tube at the air inlet into the freezer compartment. The inner diameter of the first-stage capillary tube is larger than that of the second-stage capillary tube. The specific parameters need to be determined based on the overall equipment specifications and the requirements for the latex pillows being produced, so that the cooling effect at the air inlet is lower than the cooling effect inside the freezer compartment. This provides a pre-cooling effect before freezing the latex pillows, preventing the temperature of the latex pillows from changing too quickly and affecting the quality of the finished product.

[0039] 3. Place the sealing mold on the upper surface of the mold tray and send it into the upper surface of the sealing door on one side of the freezer compartment by other transport structures. Then, send it into the upper surface of the second conveyor belt inside the freezer compartment by the first conveyor belt. After freezing, send it out through the first conveyor belt on the upper surface of the sealing door on the other side. The sealing mold is relatively fixed on the upper surfaces of the first and second conveyor belts by mutual attraction between the magnetic strip and the metal base plate. This eliminates the need for a limiting structure inside the freezer compartment and also avoids slippage during transport due to insufficient friction of the conveyor belt.

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] Please see Figure 1-8 In this embodiment of the present invention, a latex freezer includes a main body 1, a material conveying structure 2, a door control structure 3, and a refrigeration system 4. The main body 1 includes a freezing chamber 101; the material conveying structure 2 is movably installed at the bottom of the freezing chamber 101; the number of door control structures 3 is two sets, and the two sets of door control structures 3 are fixedly installed on both sides of the freezing chamber 101; the refrigeration system 4 includes a compressor refrigeration unit 401, the air inlet of the compressor refrigeration unit 401 is interconnected with the air supply pipe 402, and one end of the air supply pipe 402 is interconnected with both sides of the air supply branch pipe 403, and the air supply branch pipe... One end of pipe 403 is connected to the primary capillary tube 404, and the other end of the primary capillary tube 404 is connected to the first cooling tube coil 405. One end of the first cooling tube coil 405 is connected to the secondary capillary tube 406, and one end of the secondary capillary tube 406 is connected to the second cooling tube coil 407. The secondary capillary tube 406 and the second cooling tube coil 407 are embedded inside the wall of the refrigeration chamber 101. The lower ends of the two second cooling tube coils 407 are connected to the return gas pipe 408, and the return gas pipe 408 is connected to the return gas port of the compressor refrigeration unit 401.

[0051] Specifically, the latex pillow is first fed into the freezing chamber 101 via the conveying structure 2 and the sealing mold. Then, the front and rear openings of the freezing chamber 101 are closed by the control door structure 3. The refrigerant is then fed into the gas supply pipe 402 by the compressor refrigeration unit 401. After being split by the gas supply branch pipe 403, the refrigerant passes through two sets of primary capillary tubes 404 for initial cooling before entering the first cooling coil 405. After being cooled again by the secondary capillary tubes 406, the refrigerant passes through the second cooling coil 407, providing a low-temperature environment for the interior of the freezing chamber 101. The latex pillow is frozen and cured. Finally, the refrigerant flows back into the compressor refrigeration unit 401 after being collected through the return pipe 408. The refrigerant delivery path is optimized into two branches, which are arranged on both sides of the freezer 101. This ensures that the cold environment inside the freezer 101 is evenly distributed and improves the freezing effect. At the same time, the refrigerant passes through the first-stage capillary tube 404 and the second-stage capillary tube 406 in sequence, ensuring that the refrigerant evaporates more completely and can absorb a large amount of heat. The cooling effect is improved through the pipeline structure itself.

[0052] Example 1

[0053] like Figure 2-3As shown, in this embodiment, the main body 1 of the device also includes a sealing slot 102, an air inlet 103, a first fan 104, a second fan 105, and support legs 106. The sealing slots 102 are provided at the openings on the front and rear sides of the freezer chamber 101; the air inlet 103 is inserted into the upper side of the freezer chamber 101, and the first cooling coil 405 is embedded in the inner wall of the air inlet 103; the first fan 104 is fixedly installed at the upper opening of the air inlet 103; the second fan 105 is fixedly installed at the bottom side of the freezer chamber 101; and support legs 106 are fixedly installed at the four corners of the bottom side of the freezer chamber 101.

[0054] In this embodiment, before the sealing slots 102 at the front and rear of the freezer chamber 101 are closed, when the refrigeration system 4 is in operation, the freezer chamber 101 is open at the front and rear, automatically dissipating the cold air inside the freezer chamber 101. At the same time, the first fan 104 is activated, blowing the air cooled by the first-stage capillary tube 404 at the air inlet 103 into the freezer chamber 101. The inner diameter of the first-stage capillary tube 404 is larger than that of the second-stage capillary tube 406. The specific parameters need to be determined according to the overall equipment specifications and the requirements for the latex pillows to be produced, so that the cooling effect at the air inlet 103 is lower than the cooling effect inside the freezer chamber 101, providing a pre-cooling effect before the latex pillow is frozen, and avoiding the latex pillow temperature changing too quickly, which would affect the quality of the finished product.

[0055] like Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the control door structure 3 includes a third motor 301, a gear 302, a rack 303, a limiting sleeve 304, a hanging rod 305, and a sliding column 306. The third motor 301 is embedded in the middle of both sides of the freezer chamber 101; the gear 302 is fixedly installed at the output end of the third motor 301; the rack 303 is meshed on both the upper and lower sides of the gear 302; the limiting sleeve 304 is fixedly installed on the side surface of the freezer chamber 101, and the rack 303 passes through the limiting sleeve 304; the hanging rod 305 is hinged to one end of the limiting sleeve 304; one end of the sliding column 306 is hinged to the hanging rod 305, and the other end of the sliding column 306 is slidably engaged with the compensation groove 202.

[0056] In practice, after precooling, the No. 3 motor 301 rotates the gear 302, which in turn causes the two racks 303 to move in opposite directions, thereby pulling the lifting rod 305 back into the limiting sleeve 304. As the lifting rod 305 retracts, it tends to be horizontal. Then, the sliding column 306 pulls the sealing door 201 to rotate, and finally it is locked into the sealing groove 102, sealing the openings on the front and rear sides of the freezer 101. This makes the freezer 101 relatively closed, limiting the escape of low temperature inside the freezer 101 and improving the freezing effect.

[0057] Example 2

[0058] Based on Example 1, in order to supplement the specific method of transporting the latex pillow loaded in the sealed mold in the freezer 101, which was not mentioned in Example 1.

[0059] like Figure 2 and Figure 4 As shown, in this embodiment, the material conveying structure 2 further includes a sealing gate 201, a compensating chute 202, a first conveyor belt 203, a first motor 204, a second conveyor belt 205, a second motor 206, a hinge unit 207, a magnetic strip 208, and a mold support plate 209. One side of the sealing gate 201 is hinged to the lower edge of the sealing slot 102; compensating chute 202s are provided on both sides of the sealing gate 201; the first conveyor belt 203 is embedded in the upper surface of the sealing gate 201; the first motor 204 is fixedly installed on one side edge of the bottom of the sealing gate 201, and the output end of the first motor 204 is connected to the bottom drive roller of the first conveyor belt 203. One end is linked by gears; the second conveyor belt 205 is embedded in the bottom of the freezer chamber 101; the second motor 206 is embedded in the bottom of the freezer chamber 101, and the output end of the second motor 206 is fixedly connected to one end of the drive roller inside the second conveyor belt 205; the first conveyor belt 203 and the second conveyor belt 205 are both composed of several hinge units 207 that are hinged to each other end to end; the magnetic strip 208 is embedded in the middle of the hinge unit 207; the mold is clamped on the upper surface of the mold support plate 209, and a metal base plate 210 is fixedly installed at the bottom of the mold support plate 209, and the bottom side of the metal base plate 210 is attracted to the magnetic strip 208.

[0060] In practice, the sealing mold is placed on the upper surface of the mold tray 209 and sent to the upper surface of the sealing door 201 on one side of the freezer 101 by other transport structures. It is then sent to the upper surface of the second conveyor belt 205 inside the freezer 101 by the first conveyor belt 203. After freezing, it is sent out through the first conveyor belt 203 on the upper surface of the sealing door 201 on the other side. The sealing mold is attracted to the metal base plate 210 by the magnetic strip 208, so that the position of the sealing mold on the upper surfaces of the first conveyor belt 203 and the second conveyor belt 205 is relatively limited. This eliminates the need for a limiting structure inside the freezer 101 and also avoids insufficient friction of the conveyor belt, which could cause slippage during transport.

[0061] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0062] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
