Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and more particularly to a refrigerant pipe cutting device for installation in a constant-temperature cold storage. Background Art

[0002] Refrigerant pipes serve as refrigerant transmission channels, ensuring smooth refrigerant flow between various parts of the cold storage system, thereby achieving cooling efficiency. They play a crucial role in constant-temperature cold storage. Existing refrigerant pipe cutting methods often use a single-group cutting mode. After the cutting blade completes a single cut of the refrigerant pipe, it must wait for the next feed from the feed mechanism before it can begin cutting again. This results in a disconnected cutting process, impacting cutting efficiency. Given this, we propose a refrigerant pipe cutting device for constant-temperature cold storage installations. Summary of the Invention

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0039] Reference Figures 1 to 9The present embodiment discloses a refrigerant pipe cutting device for installation in a constant temperature cold storage, including a support assembly 1. The support assembly 1 includes a cutting table 11 and a conveying frame 12 fixedly installed on one side of the cutting table 11. A plurality of conveying rollers 13 are installed on the conveying frame 12. Two sets of discharge hoppers 14 are provided on the cutting table 11. A plurality of baffles 15 and a plurality of guide rod racks 16 are fixedly installed on the cutting table 11. The baffles 15 are distributed on both sides of the discharge hopper 14 to ensure that the cut refrigerant pipe can fall smoothly into the discharge hopper 14.

[0040] Reference Figure 1 、 Figure 3 and Figure 4 Two sets of feeding assemblies 2 are installed on the conveying frame 12. The feeding assembly 2 includes a fixed plate 21 installed on the conveying frame 12, a first motor 22 is fixedly installed on the fixed plate 21, and the output shaft of the first motor 22 is fixedly connected to a screw rod 23 rotatably connected to the fixed plate 21. A movable plate 24 threadedly matched with the screw rod 23 is slidably connected to the fixed plate 21, thereby forming an electric platform. A fixed frame 25 is fixedly installed on the movable plate 24, and a first cylinder 26 is fixedly installed on the fixed frame 25. The output shaft of the first cylinder 26 is fixedly installed with a first pressing plate 27 slidably connected to the fixed frame 25. A fixed column is fixedly installed on the movable plate 24, and a top plate 28 is slidably connected to the fixed column. A first elastic member 29 is mounted on the fixed column, one end of the first elastic member 29 is fixedly connected to the top plate 28, and the other end is fixedly connected to the movable plate 24. The first elastic member 29 is used to pull the top plate 28 closer to the movable plate 24. Two groups of inclined blocks 210 for controlling the lifting of the top plate 28 are slidably connected to the movable plate 24. A number of second elastic members 211 for pulling the inclined block 210 to move toward the outside of the movable plate 24 are installed on the movable plate 24. When the inclined block 210 moves toward the outside of the movable plate 24, the final position is controlled by the positioning block. Both ends of the first pressing plate 27 are fixedly installed with a push rod 212 for pushing the inclined block 210 to move, and an inclined surface is provided on the push rod 212 and the inclined block 210.

[0041] The output shaft of the first motor 22 drives the screw rod 23 to rotate, and the screw rod 23 drives the movable plate 24 to move on the fixed plate 21, thereby adjusting the position of the top plate 28 and the first pressure plate 27. When the top plate 28 and the first pressure plate 27 are in the non-clamping state, the top plate 28 is lower than the height of the conveying roller 13, ensuring that the bottom does not contact the refrigerant pipe, thereby avoiding the refrigerant pipe from following the movement when the top plate 28 moves toward the side of the conveying roller 13. After moving to the set position, the first pressure plate 27 is pressed down, and the inclined surface of the top rod 212 contacts the inclined block 210 and pushes the two groups of inclined blocks 210 to move toward each other, so that the inclined surface of the inclined block 210 contacts the top plate 28 and pushes the top plate 28 to move up to the same height as the conveying roller 13 and maintain it. The first pressure plate 27 continues to press down to cooperate with the top plate 28 to clamp the refrigerant pipe. When the movable plate 24 moves again, the loading and transportation of the refrigerant pipe can be realized.

[0042] Reference Figure 1 、 Figure 5 and Figure 6 The cutting table 11 is installed on the cutting assembly 3, and the cutting assembly 3 includes a telescopic cylinder 31 rotatably mounted on the cutting table 11, and the output shaft of the telescopic cylinder 31 is rotatably connected to the adjusting frame 32. The adjusting frame 32 is fixedly mounted with a support shaft 33 rotatably connected to the cutting table 11, and two sets of transmission shafts 34 are rotatably connected to the adjusting frame 32. A cutting blade 35 is fixedly mounted on the transmission shaft 34, and a second motor 36 is fixedly mounted on the adjusting frame 32. The cutting blades 35 are distributed on both sides of the support shaft 33, and the output shafts of the transmission shaft 34 and the second motor 36 are fixedly mounted with pulleys. The two adjacent pulleys are driven by a belt, so that the output shaft of the second motor 36 drives the two sets of transmission shafts 34 to rotate at the same time, thereby driving the cutting blade 35 to cut, and one end of the support shaft 33 is fixedly mounted with a gear 37. During operation, the output shaft of the telescopic cylinder 31 pushes up or retracts to control the swing state of the adjustment frame 32, thereby controlling the two groups of cutting blades 35 to cut alternately and improve the cutting effect. When one cutting blade 35 is cutting, the feeding assembly 2 corresponding to the other cutting blade 35 feeds synchronously, thereby reducing the cutting pause time of feeding and improving the cutting efficiency and cutting continuity.

[0043] Reference Figure 1 、 Figure 5 、 Figures 7 to 9 , two groups of clamping assemblies 4 corresponding to the two groups of cutting blades 35 are installed on the cutting table 11, and the clamping assembly 4 includes a fixed seat 41 and a lifting plate 42 fixedly mounted on the cutting table 11. The upper surface height of the fixed seat 41 is equal to the top height of the conveying roller 13. The lifting plate 42 is slidably connected to the cutting table 11 through the guide rod frame 16. A rack 43 is fixedly mounted on one end of the lifting plate 42. The racks 43 of the two groups of clamping assemblies 4 are engaged with the gear 37 and are distributed on both sides of the gear 37, thereby realizing staggered movement, that is, when one rack 43 rises, the other rack 43 falls. A first clamping plate 44 is slidably connected to the bottom of the lifting plate 42, and a third elastic member 45 is installed on the lifting plate 42 for pushing the first clamping plate 44 away from the lifting plate 42.

[0044] The two ends of the first clamping plate 44 are fixedly installed with a second pressure plate 46 that is slidably connected to the guide rod frame 16. The clamping assembly 4 also includes a second clamping plate 47. The second clamping plate 47 is slidably connected to the fixed seat 41 through a telescopic rod. The fixed seat 41 is equipped with a fourth elastic member 48 for pushing the second clamping plate 47 up. The second pressure plate 46 is overlapped on the top of the second clamping plate 47 and the second clamping plate 47 and the first clamping plate 44 have the same thickness, thereby ensuring that the clamping height of the first clamping plate 44 and the second clamping plate 47 are equal. A cutting groove 49 and an adjustment groove 410 are opened on the fixed seat 41, and the cutting blade 35 is above the corresponding cutting groove 49.

[0045] When the telescopic cylinder 31 controls the adjustment frame 32 to rotate, the gear 37 will drive the rack 43 on the working side to descend and the rack 43 on the non-working side to rise. When the rack 43 on the working side descends, the first clamping plate 44 and the second clamping plate 47 will clamp and fix the refrigerant tubes on both sides of the cutting line before the cutting blade 35 contacts the refrigerant tube, effectively ensuring the stability of the cutting point and improving the flatness of the end face cutting of the refrigerant tube. The non-working first clamping plate 44 and the second clamping plate 47 will rise and break away from the clamping state, and synchronous loading can be achieved during the cutting process on the opposite side. By alternating the two sets of cutting blades 35, the fixing and cutting efficiency can be improved, and the control difficulty of the control system can be reduced.

[0046] Reference Figure 7 and Figure 9 A first limiting assembly 5 is installed on the fixed seat 41. The first limiting assembly 5 includes a double-threaded rod 51 rotatably connected to the fixed seat 41. The double-threaded rod 51 is in the adjusting groove 410. The double-threaded rod 51 is threaded with two groups of limiting plates 52 sliding on the fixed seat 41. The two groups of limiting plates 52 move toward or away from each other, thereby controlling the limiting spacing on both sides of a number of refrigerant pipes, further reducing the risk of movement during the cutting process of the refrigerant pipes. A handwheel 53 is installed at the end of the double-threaded rod 51. Along the conveying direction of the refrigerant pipe, the limiting plate 52 is located in front of the cutting groove 49.

[0047] Reference Figure 1 Two sets of second limiting components 6 are installed on the conveying frame 12. The second limiting components 6 are located between the two conveying rollers 13 close to the feeding component 2. The only difference between the second limiting component 6 and the first limiting component 5 is that the double-threaded rod 51 of the second limiting component 6 is rotatably connected to the conveying frame 12, and the limiting plate 52 of the second limiting component 6 is slidably connected to the conveying frame 12.

[0048] Reference Figure 1 and Figure 2 Two sets of positioning assemblies 7 are installed on the cutting table 11. The positioning assembly 7 includes a second cylinder 71 installed on the cutting table 11. The output shaft of the second cylinder 71 is fixedly installed with a support table 72 that is slidably connected to the cutting table 11. A moving tube 73 is slidably connected to the support table 72. A positioning plate 74 is fixedly installed at the end of the moving tube 73. The positioning plate 74 corresponds to the position of the discharge hopper 14. A screw 75 that is threadedly engaged with the moving tube 73 is rotatably connected to the support table 72 and is used to adjust the position of the positioning plate 74. By setting the second cylinder 71 and the screw 75, the position of the positioning plate 74 can be adjusted in a large or small range, thereby positioning the cutting length of the refrigerant pipe. It should be noted that a pressure sensor can be set on the positioning plate 74 to determine whether the refrigerant pipe is in contact with the positioning plate 74, and the movement stroke of the device can be monitored by a displacement sensor, which will not be described here.

[0049] Working principle: The output shaft of the second cylinder 71 drives the support platform 72 to move and cooperates with the rotation of the screw 75 to adjust the positioning point of the positioning plate 74. The vertical distance between the positioning plate 74 and the cutting blade 35 is the cutting length. The refrigerant tube to be cut is placed on the conveyor roller 13, and then divided into two groups and passed between the first pressure plate 27 and the top plate 28, under the first clamping plate 44 and under the second clamping plate 47. The end of the refrigerant tube is pressed against the positioning plate 74. The distance between the limiting plates 52 on the first limiting assembly 5 and the second limiting assembly 6 is adjusted by rotating the double-threaded rod 51 to limit the two sides of the refrigerant tube.

[0050] To facilitate the description of the continuous cutting action, it is assumed that the initial position of the movable plate 24 is close to the cutting table 11, the first pressing plate 27 and the top plate 28 are both in a state of clamping the refrigerant tube, and the adjustment frame 32 is in a horizontal state.

[0051] The return stroke of the output shaft of the telescopic cylinder 31 drives the adjusting frame 32, the supporting shaft 33 and the gear 37 to rotate, and drives the rack 43 on the side to be cut to descend through the meshing transmission, and the rack 43 on the non-cutting side to rise. The descending rack 43 drives the lifting plate 42, the first clamping plate 44, the second pressure plate 46 and the second clamping plate 47 to descend. The first clamping plate 44 and the second clamping plate 47 cooperate with the fixing seat 41 to synchronously clamp and fix the refrigerant tubes on both sides of the cutting line. The telescopic cylinder 31 drives the adjusting frame 32 to rotate further, the third elastic member 45 and the fourth elastic member 48 are continuously compressed, and the cutting blade 35 cuts the refrigerant tube.

[0052] After the refrigerant pipe is clamped and fixed by the first clamping plate 44 and the second clamping plate 47, the corresponding feeding assembly 2 stops the clamping action and moves away from the cutting table 11. Specifically, the output shaft of the first cylinder 26 drives the first pressure plate 27 to move upward, and the push rod 212 disengages from the inclined block 210. The inclined block 210 moves to both sides of the movable plate 24 driven by the second elastic member 211. The top plate 28 descends under the action of the first elastic member 29 and disengages from the contact with the bottom of the refrigerant pipe to avoid interference with the refrigerant pipe during movement. The movable plate 24 drives the top plate 28 to move upward. The plate 28 and the first pressure plate 27 move toward the side of the conveying roller 13. After moving to the set position, the first pressure plate 27 and the top plate 28 clamp the refrigerant tube again. This process is the reverse process of disengaging from the clamping and will not be described in detail. It should be noted that when the inclined block 210 pushes the top plate 28 to move to the highest point, the upper end surface of the top plate 28 is at the same height as the top of the conveying roller 13, that is, it contacts the bottom of the refrigerant tube, and the first pressure plate 27 and the top plate 28 clamp the refrigerant tube again before the cutting action, further ensuring the stability of the cutting process.

[0053] After the refrigerant tube on one side is cut, the output shaft of the telescopic cylinder 31 controls the adjustment frame 32 to rotate in the opposite direction, and the high-speed rotating cutting blade 35 follows the movement. At the same time, driven by the gear 37, the two sets of racks 43 move in the opposite direction, thereby causing the first clamping plate 44 and the second clamping plate 47 on the side of the cut refrigerant tube to rise and gradually disengage from the clamping of the refrigerant tube. The cut refrigerant tube falls from the discharge hopper 14, and the corresponding movable plate 24 of the feeding assembly 2 moves toward the cutting table 11 for re-loading. It should be noted that the cutting blade 35 first disengages from the refrigerant tube, and the first clamping plate 44 and the second clamping plate 47 then stop clamping to prevent the refrigerant tube from contacting the cutting blade 35 during the material drop.

[0054] As the telescopic cylinder 31 continues to push, the first clamping plate 44 and the second clamping plate 47 on the other side clamp the refrigerant tube, and then the cutting blade 35 cuts the clamped refrigerant tube. The principle is the same as the above, and no further details will be given here. By repeating the above cutting process, uninterrupted cutting and feeding can be achieved.

[0055] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
