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

[0002] As the transmission channel of the refrigerant, the refrigerant pipe ensures that the refrigerant can flow smoothly between various parts of the cold storage system, thereby achieving the cooling effect, and plays a vital role in the constant temperature cold storage. When cutting the existing refrigerant pipe, it is mostly a single-group cutting mode. The cutting blade cuts the refrigerant pipe once, and it needs to wait for the next feeding of the feeding mechanism before the cutting blade cuts again, which leads to the incoherence of the two cutting processes and affects the cutting efficiency. In view of this, we propose a refrigerant pipe cutting device for constant temperature cold storage installation. Summary of the invention

[0009] As a further description of the above technical solution, it further includes a first limiting assembly. The first limiting assembly includes a double threaded rod rotatably connected to the fixed seat. An adjustment groove is provided on the fixed seat. The double threaded rod is located in the adjustment groove. Two groups of limiting plates sliding on the fixed seat are in threaded cooperation with the double threaded rod.

Detailed implementation manners

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0019] Refer to Figures 1 to 9 , this embodiment discloses a refrigerant pipe cutting device for installation of 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 groups of discharge hoppers 14 are arranged on the cutting table 11. A plurality of baffles 15 and a plurality of guide rod frames 16 are fixedly installed on the cutting table 11. The baffles 15 are distributed on both sides of the discharge hoppers 14 to ensure that the cut refrigerant pipes can smoothly fall into the discharge hoppers 14.

[0020] Refer to Figure 1 , Figure 3 and Figure 4, two sets of feeding components 2 are installed on the conveying frame 12. The feeding component 2 includes a fixing plate 21 installed on the conveying frame 12. A first motor 22 is fixedly installed on the fixing plate 21. The output shaft of the first motor 22 is fixedly connected to a lead screw 23 rotatably connected to the fixing plate 21. A moving plate 24 threadedly engaged with the lead screw 23 is slidably connected to the fixing plate 21, thus forming an electric platform. A fixing frame 25 is fixedly installed on the moving plate 24. A first cylinder 26 is fixedly installed on the fixing frame 25. The output shaft of the first cylinder 26 is fixedly installed with a first pressing plate 27 slidably connected to the fixing frame 25. A fixing column is fixedly installed on the moving plate 24. A top plate 28 is slidably connected to the fixing column. A first elastic member 29 is sleeved on the fixing 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 moving plate 24. The first elastic member 29 is used to pull the top plate 28 closer to the moving plate 24. Two sets of inclined blocks 210 for controlling the lifting of the top plate 28 are slidably connected to the moving plate 24. A number of second elastic members 211 for pulling the inclined blocks 210 to move outward from the moving plate 24 are installed on the moving plate 24. When the inclined blocks 210 move outward from the moving plate 24, their final positions are controlled by positioning blocks. Push rods 212 for pushing the inclined blocks 210 to move are fixedly installed at both ends of the first pressing plate 27. Inclined surfaces are provided on both the push rods 212 and the inclined blocks 210.

[0021] The output shaft of the first motor 22 drives the lead screw 23 to rotate, and the lead screw 23 drives the moving plate 24 to move on the fixing plate 21, thereby realizing the adjustment of the positions of the top plate 28 and the first pressing plate 27. When the top plate 28 and the first pressing plate 27 are in a non-clamping state, the height of the top plate 28 is lower than that of the conveying roller 13, ensuring that the bottom does not contact the refrigerant pipe, so as to prevent the refrigerant pipe from moving along when the top plate 28 moves towards the conveying roller 13 side. After moving to the set position, the first pressing plate 27 presses down, and the inclined surface of the push rod 212 contacts and pushes the two sets of inclined blocks 210 to move towards each other, so that the inclined surface of the inclined block 210 contacts and pushes the top plate 28 to move upward to be equal in height to the conveying roller 13 and remain so. The first pressing plate 27 continuously presses down and cooperates with the top plate 28 to clamp the refrigerant pipe. When the moving plate 24 moves again, the feeding and conveying of the refrigerant pipe can be realized.

[0022] Refer to Figure 1 , Figure 5 and Figure 6, a cutting assembly 3 is installed on the cutting table 11. The cutting assembly 3 includes a telescopic cylinder 31 rotatably installed on the cutting table 11. The output shaft of the telescopic cylinder 31 is rotatably connected to an adjusting frame 32. A support shaft 33 rotatably connected to the cutting table 11 is fixedly installed on the adjusting frame 32. Two groups of transmission shafts 34 are rotatably connected to the adjusting frame 32. Cutting blades 35 are fixedly installed on the transmission shafts 34. A second motor 36 is fixedly installed on the adjusting frame 32. The cutting blades 35 are distributed on both sides of the support shaft 33. Pulley wheels are fixedly installed on both the transmission shafts 34 and the output shaft of the second motor 36. Adjacent pulley wheels are driven by a belt, so that the output shaft of the second motor 36 drives the two groups of transmission shafts 34 to rotate simultaneously, and then drives the cutting blades 35 to perform cutting operations. A gear 37 is fixedly installed at one end of the support shaft 33. During operation, the output shaft of the telescopic cylinder 31 pushes or retracts to control the swinging state of the adjusting frame 32, so as to control the two groups of cutting blades 35 to cut alternately, improving the cutting effect. When one cutting blade 35 is performing a cutting operation, the feeding assembly 2 corresponding to the other cutting blade 35 feeds synchronously, thereby reducing the cutting pause time during feeding and improving the cutting efficiency and the continuity of cutting.

[0023] Refer to Figure 1 , Figure 5 , Figures 7 to 9 , two groups of clamping assemblies 4 corresponding to the two groups of cutting blades 35 respectively are installed on the cutting table 11. The clamping assembly 4 includes a fixed seat 41 fixedly installed on the cutting table 11 and a lifting plate 42. The height of the upper surface 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 a guide rod frame 16. A rack 43 is fixedly installed at one end of the lifting plate 42. The racks 43 of the two groups of clamping assemblies 4 are both engaged with the gear 37 and are distributed on both sides of the gear 37, so as to achieve a staggered movement, that is, when one rack 43 rises, the other rack 43 descends. A first clamping plate 44 is slidably connected below the lifting plate 42. A third elastic member 45 for pushing the first clamping plate 44 away from the lifting plate 42 is installed on the lifting plate 42. Second pressing plates 46 slidably connected to the guide rod frame 16 are fixedly installed at both ends of the first clamping plate 44. The clamping assembly 4 further includes a second clamping plate 47. The second clamping plate 47 is slidably connected to the fixed seat 41 through a telescopic rod. A fourth elastic member 48 for pushing the second clamping plate 47 to rise is installed on the fixed seat 41. The second pressing plate 46 overlaps the top of the second clamping plate 47 and the thicknesses of the second clamping plate 47 and the first clamping plate 44 are equal, so as to ensure that the clamping heights of the first clamping plate 44 and the second clamping plate 47 are equal. A cutting groove 49 and an adjusting groove 410 are formed on the fixed seat 41. The cutting blade 35 is located above the corresponding cutting groove 49.

[0024] 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. The two sets of cutting blades 35 work alternately, thereby improving the fixing and cutting efficiency and reducing the control difficulty of the control system.

[0025] Reference Figure 7 and Figure 9 A first limit assembly 5 is installed on the fixed seat 41, and the first limit assembly 5 includes a double-threaded rod 51 rotatably connected to the fixed seat 41, and the double-threaded rod 51 is in the adjustment groove 410. The double-threaded rod 51 is threaded with two groups of limit plates 52 sliding on the fixed seat 41. The two groups of limit plates 52 move toward or away from each other, thereby controlling the limit spacing on both sides of a number of refrigerant pipes, further reducing the risk of movement during the cutting process of the refrigerant pipes, and a hand wheel 53 is installed at the end of the double-threaded rod 51. Along the conveying direction of the refrigerant pipe, the limit plate 52 is located on the front side of the cutting groove 49.

[0026] Reference Figure 1 Two sets of second limiting assemblies 6 are installed on the conveying frame 12. The second limiting assemblies 6 are located between the two conveying rollers 13 close to the feeding assembly 2. The difference between the second limiting assemblies 6 and the first limiting assemblies 5 is that the double threaded rod 51 of the second limiting assemblies 6 is rotatably connected to the conveying frame 12, and the limiting plate 52 of the second limiting assemblies 6 is slidably connected to the conveying frame 12.

[0027] Reference Figure 1 and Figure 2 , two sets of positioning components 7 are installed on the cutting table 11. The positioning component 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 matched with the moving tube 73 is rotatably connected to the support table 72 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 moving stroke of the device can be monitored by a displacement sensor, which will not be repeated here.

[0028] Working principle: The output shaft of the second cylinder 71 drives the support table 72 to move and cooperates with the rotation of the screw rod 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. Place the refrigerant pipe to be cut on the conveying roller 13, then divide it into two groups and pass through between the first pressing 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 pipe abuts against the positioning plate 74. By rotating the double threaded rod 51, the distance between the limiting plates 52 on the first limiting assembly 5 and the second limiting assembly 6 is adjusted to limit both sides of the refrigerant pipe.

[0029] For the convenience of describing the continuous cutting operation, assume that the initial position of the moving plate 24 is on the side close to the cutting table 11, and both the first pressing plate 27 and the top plate 28 are in the state of clamping the refrigerant pipe, and the adjusting frame 32 is in a horizontal state.

[0030] The return stroke of the output shaft of the telescopic cylinder 31 drives the adjusting frame 32, the support shaft 33 and the gear 37 to rotate. Through meshing transmission, the rack 43 on the side to be cut descends, and the rack 43 on the non-cutting side ascends. The descending rack 43 drives the lifting plate 42, the first clamping plate 44, the second pressing plate 46 and the second clamping plate 47 to descend. The first clamping plate 44 and the second clamping plate 47 cooperate with the fixed seat 41 to clamp and fix the refrigerant pipes on both sides of the cutting line synchronously. The telescopic cylinder 31 drives the adjusting frame 32 to rotate further, and the third elastic member 45 and the fourth elastic member 48 continue to be compressed, and the cutting blade 35 cuts the refrigerant pipe.

[0031] 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 pressing plate 27 to move upward, the ejector rod 212 disengages from the inclined block 210, and the inclined block 210 moves to both sides of the moving 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 contacting the bottom of the refrigerant pipe to avoid interference with the refrigerant pipe during movement. The moving plate 24 drives the top plate 28 and the first pressing plate 27 to move toward the conveying roller 13 side. After moving to the set position, the first pressing plate 27 and the top plate 28 clamp and fix the refrigerant pipe again. This process is the reverse process of releasing the clamping and will not be elaborated. 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, in contact with the bottom of the refrigerant pipe, and the first pressing plate 27 and the top plate 28 clamp the refrigerant pipe again before the cutting action to further ensure the stability of the cutting process.

[0032] After the cutting of the refrigerant pipe on one side is completed, the output shaft of the telescopic cylinder 31 controls the regulating frame 32 to rotate in the reverse direction, and the high-speed rotating cutting blade 35 moves accordingly. At the same time, driven by the gear 37, the two groups of racks 43 move in the reverse direction, causing the first clamping plate 44 and the second clamping plate 47 on the side of the cut refrigerant pipe to rise and gradually release the clamping of the refrigerant pipe. The cut refrigerant pipe falls from the discharge hopper 14, and the moving plate 24 of the corresponding feeding assembly 2 moves towards the cutting table 11 for reloading. It should be noted that the cutting blade 35 disengages from the refrigerant pipe first, and the first clamping plate 44 and the second clamping plate 47 stop clamping later to prevent the refrigerant pipe from contacting the cutting blade 35 during the falling process.

[0033] With the continuous pushing of the telescopic cylinder 31, the first clamping plate 44 and the second clamping plate 47 on the other side clamp the refrigerant pipe, and then the cutting blade 35 cuts the clamped refrigerant pipe. The principle is the same as described above and will not be elaborated here. By repeating the above cutting process, continuous cutting and feeding can be achieved.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
