Description

Technical Field

[0001] The present invention relates to the technical field of heat shrink packaging, and particularly relates to a heat shrink packaging machine for ion exchange resin membranes. Background Art

[0002] Heat shrink packaging is a common packaging technology, mainly used for protecting products, enhancing the appearance attractiveness of products, and facilitating transportation. Its core principle is to use special heat shrink materials that shrink and tightly fit on the product under heating conditions. Ion exchange resin is a functional polymer material with ion exchange characteristics. It is widely used in fields such as water treatment, chemical industry, pharmaceuticals, and food. Existing ion exchange resins are generally fixedly arranged inside a square frame during production. During use, the ion exchange resin is fixed in a water purification tank through the frame to perform ion exchange on the wastewater in the water purification tank. To improve the ion exchange efficiency of the ion exchange resin, the upper and lower ends of the frame are set as a symmetric structure with the same arc, and the side surface of the frame is a vertical structure. This structure improves the support performance of the frame while enhancing the exchange performance of the ion exchange resin membrane.

[0003] In the prior art, when transporting ion exchange resins, to prevent resin bumps and dust adhesion, a layer of isolation film is generally coated on the surface of the resin. When the existing heat shrink packaging machine covers the film on the resin surface through air pressure, the gas pressure is relatively large, which easily damages the resin surface. Therefore, it cannot tightly cover a curved surface structure with a certain arc under the premise of a small pressure, resulting in an increase in the volume of the ion exchange resin after film covering, making it inconvenient for transportation. Moreover, when covering the film, the isolation film cannot be completely tightly attached to the surface of the ion exchange resin, and there are relatively large gaps remaining between the isolation film and the resin. During long-term transportation, dust and other impurities in the gaps will fall into the pores on the surface of the ion exchange resin, causing a decline in the quality of the ion exchange resin. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks existing in the background art and to propose a heat shrink packaging machine for ion exchange resin membranes.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows: An ion exchange resin off-membrane heat shrink packaging machine includes a main body plate. At the upper end of the main body plate, there is a rotating edge-sealing mechanism for heat-sealing the upper isolation film on the surface of the ion exchange resin. The rotating edge-sealing mechanism includes two first limiting grooves symmetrically opened on the side surface of the main body plate. Two first limiting bodies are respectively slidably fitted in the two first limiting grooves. The upper ends of the two first limiting bodies are respectively fixedly connected with first electric telescopic rods. The telescopic ends of the two first electric telescopic rods are fixedly connected with a first fixing body. A second limiting groove is opened at the lower end of the first fixing body. A second limiting body is slidably fitted in the second limiting groove. At the upper end of the main body plate, there is a rotating film-covering mechanism for winding the film on the resin surface. At the upper end of the main body plate, there is a supporting mechanism for clamping the resin.

[0006] Preferably, a first empty groove is opened at the lower end of the second limiting body. A third motor is fixedly connected in the first empty groove. The transmission shaft end of the third motor is fixedly connected with a second electric telescopic rod. The telescopic end of the second electric telescopic rod is fixedly connected with a double-shaft electric telescopic rod. The telescopic ends of the double-shaft electric telescopic rod are respectively fixedly connected with first pressure sensors. The ends of the two first pressure sensors are fixedly connected with a second fixing body.

[0007] Preferably, second empty grooves are respectively opened on the inner sides of the two second fixing bodies. Fourth motors are respectively fixedly connected in the two second empty grooves. The transmission shaft ends of the two fourth motors are respectively fixedly connected with rollers. Heating sheets are respectively fixedly connected to the side surfaces of the two rollers. Batteries are respectively arranged on the inner sides of the two heating sheets. The batteries and the heating sheets are connected by electric wires.

[0008] Preferably, first motors are respectively fixedly connected in the two first limiting grooves. The transmission shaft ends of the two first motors are respectively fixedly connected with first threaded rods. The sides of the two first threaded rods are respectively in threaded cooperation with the first limiting bodies.

[0009] Preferably, a second motor is fixedly connected to the side surface of the first fixing body. The transmission shaft end of the second motor is fixedly connected with a second threaded rod in the second limiting groove. The side of the second threaded rod is in threaded cooperation with the second limiting body.

[0010] Preferably, the rotating film-covering mechanism includes a placement groove opened at the upper end of the main body plate. A cavity communicating with the placement groove is opened at the upper end of the main body plate. A fifth motor is fixedly connected in the cavity. The transmission shaft end of the fifth motor is fixedly connected with a gear. A toothed ring is rotatably arranged in the placement groove. The toothed ring is meshed with the gear. A connecting plate is fixedly connected to the upper end of the toothed ring.

[0011] Preferably, a third fixing body is fixedly connected to the upper end of the connecting plate. A third empty groove is formed on one side of the third fixing body. A sixth motor is fixedly connected to the upper end of the third fixing body. The transmission shaft end of the sixth motor is fixedly connected to a rotating rod in the third empty groove through a bolt. The upper end of the toothed ring is fixedly connected with a multi-stage electric telescopic rod at a position symmetrical to the connecting plate. The telescopic end of the multi-stage electric telescopic rod is fixedly connected with a third electric telescopic rod. The telescopic end of the third electric telescopic rod is fixedly connected with a second pressure sensor. The end of the second pressure sensor is fixedly connected with a heating plate. The side surface of the heating plate is an arc surface structure.

[0012] Preferably, the supporting mechanism includes a fourth empty groove formed on the upper end of the main body plate. A fourth electric telescopic rod is fixedly connected in the fourth empty groove. The telescopic end of the fourth electric telescopic rod is fixedly connected with a fourth fixing body. A fifth empty groove is formed on the upper end of the fourth fixing body. A fifth electric telescopic rod penetrates through the side surface of the fourth fixing body. The telescopic ends of several fifth electric telescopic rods are respectively fixedly connected with anti-slip sheets.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The third electric telescopic rod extends, driving the arc surface end of the heating plate to contact the side surface of the resin. The second pressure sensor at the telescopic end of the third electric telescopic rod can ensure that the heating plate just contacts the side surface of the resin. During the process of the fifth motor driving the third fixing body to rotate, the sixth motor is started synchronously. The sixth motor is connected to the third electric telescopic rod through a controller. The length of the arc surface of the arc-shaped resin can be calculated through the telescopic value of the third electric telescopic rod, so that the length of the isolation film wound out from the side surface of the rotating rod is the same as the arc length of the arc-shaped resin, ensuring that when the subsequent film is covered on the surface of the arc-shaped resin, the gap between the isolation film and the surface of the arc-shaped resin is very small, preventing the gap between the isolation film and the resin from being too large, and reducing the transportation volume of the resin after film covering;

[0015] 2. The first motor and the second motor drive the second limiting body to move along the trajectory drawn by the telescopic movement of the third electric telescopic rod. While moving, the third motor is started. The third motor rotates according to the side trajectory of the arc-shaped resin, so that the telescopic direction of the double-axis electric telescopic rod is always perpendicular to the side surface of the arc-shaped resin. The second electric telescopic rod drives the two second fixing bodies to move to the upper end of the isolation film. Then the double-axis electric telescopic rod contracts, driving the two rollers to contact the isolation film inward at the same time. Then the battery drives the heating sheet to heat, so as to heat-seal the upper isolation film, making the upper part of the arc-shaped resin be tightly covered with the film. When the film covering is completed, several fifth electric telescopic rods are contracted, the arc-shaped resin is rotated up and down, and the above steps are repeated, and the other end of the arc-shaped resin can be tightly sealed and covered with the film, improving the quality of the resin after tight film covering.

[0025] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0026] Please refer to Figures 1 - 8 , an ion exchange resin off-membrane heat shrink packaging machine, including a main body plate 1, and a rotating edge-sealing mechanism 2 for heat-sealing the upper isolation film on the surface of the ion exchange resin is arranged at the upper end of the main body plate 1.

[0027] In this embodiment, the rotating edge-sealing mechanism 2 includes two first limiting grooves 23 symmetrically opened on the side surface of the main body plate 1. Two first limiting bodies 24 are respectively slidably fitted in the two first limiting grooves 23. The upper ends of the two first limiting bodies 24 are respectively fixedly connected with first electric telescopic rods 21.

[0028] A first empty groove 211 is opened at the lower end of the second limiting body 210. A third motor 212 is fixedly connected in the first empty groove 211.

[0030] First motors 25 are respectively fixedly connected in the two first limiting grooves 23. The transmission shaft ends of the two first motors 25 are respectively fixedly connected with first threaded rods 26. The sides of the two first threaded rods 26 are respectively arranged in threaded cooperation with the first limiting bodies 24.

[0031] A second motor 27 is fixedly connected to the side surface of the first fixing body 22. The transmission shaft end of the second motor 27 is fixedly connected with a second threaded rod 29 in the second limiting groove 28. The side of the second threaded rod 29 is arranged in threaded cooperation with the second limiting body 210.

[0032] Specifically, the second motor 27 drives the second threaded rod 29 to rotate. The second threaded rod 29 cooperates to drive the second limiting body 210 to move in the second limiting groove 28. The first motor 25 and the second motor 27 drive the second limiting body 210 to move along the trajectory drawn by the telescopic movement of the third electric telescopic rod 38. While moving, the third motor 212 is started. The third motor 212 rotates according to the side trajectory of the arc-shaped resin, so that the telescopic direction of the double-shaft electric telescopic rod 214 is always perpendicular to the side of the arc-shaped resin.

[0033] In this embodiment, a rotating film covering mechanism 3 for covering the surface of the resin is provided at the upper end of the main body plate 1.

[0034] The rotating film covering mechanism 3 includes a placement groove 36 opened at the upper end of the main body plate 1. A cavity 31 communicating with the placement groove 36 is opened at the upper end of the main body plate 1. A fifth motor 33 is fixedly connected in the cavity 31. A gear 32 is fixedly connected to the transmission shaft end of the fifth motor 33. A toothed ring 34 is rotatably arranged in the placement groove 36. The toothed ring 34 is meshed with the gear 32. A connecting plate 37 is fixedly connected to the upper end of the toothed ring 34.

[0035] A third fixing body 310 is fixedly connected to the upper end of the connecting plate 37. A third empty groove 311 is opened on one side of the third fixing body 310. A sixth motor 314 is fixedly connected to the upper end of the third fixing body 310. A rotating rod 313 is fixedly connected to the transmission shaft end of the sixth motor 314 in the third empty groove 311 by bolts. Multistage electric telescopic rods 35 are fixedly connected to the upper end of the toothed ring 34 at a position symmetrical to the connecting plate 37. A third electric telescopic rod 38 is fixedly connected to the telescopic end of the multistage electric telescopic rod 35. A second pressure sensor 315 is fixedly connected to the telescopic end of the third electric telescopic rod 38. A heating plate 39 is fixedly connected to the end of the second pressure sensor 315. The side surface of the heating plate 39 is an arc surface structure.

[0036] Specifically, the fifth motor 33 drives the toothed ring 34 to rotate. The toothed ring 34 drives the third fixing body 310 to rotate with the convex surface of the arc-shaped resin first. At this time, the multistage electric telescopic rod 35 drives the third electric telescopic rod 38 to extend, so that the upper end of the heating plate 39 at the telescopic end of the third electric telescopic rod 38 is flush with the upper end of the resin. Then the third electric telescopic rod 38 extends, driving the arc surface end of the heating plate 39 to contact the side surface of the resin.

[0037] In this embodiment, a support mechanism 4 for clamping the resin is provided at the upper end of the main body plate 1.

[0038] The support mechanism 4 includes a fourth empty slot 41 opened at the upper end of the main body plate 1. A fourth electric telescopic rod 42 is fixedly connected inside the fourth empty slot 41. The telescopic end of the fourth electric telescopic rod 42 is fixedly connected with a fourth fixing body 43. A fifth empty slot 44 is opened at the upper end of the fourth fixing body 43. A fifth electric telescopic rod 45 is arranged through the side surface of the fourth fixing body 43. The telescopic ends of a plurality of the fifth electric telescopic rods 45 are respectively fixedly connected with anti-slip sheets 46.

[0039] Specifically, when a plurality of the fifth electric telescopic rods 45 contract simultaneously, the plurality of the fifth electric telescopic rods 45 extend, driving the anti-slip sheets 46 to extrude the lower frame, thereby fixing the resin.

[0040] During use, the main body plate 1 is placed on a horizontal support frame. Then, the arc-shaped resin is placed in the fifth empty slot 44 through the lower frame. At this time, a plurality of the fifth electric telescopic rods 45 contract simultaneously, and the plurality of the fifth electric telescopic rods 45 extend, driving the anti-slip sheets 46 to extrude the lower frame, thereby fixing the resin. Then, the fifth motor 33 is started. The fifth motor 33 drives the gear 32 to rotate. The gear 32 meshes with and drives the toothed ring 34 to rotate. The toothed ring 34 drives the third fixing body 310 to rotate to a position parallel to the side surface of the frame. Then, a worker bonds one end of the isolation film to the side surface of the frame through a heat melter. Then, the fifth motor 33 is started again. The fifth motor 33 drives the toothed ring 34 to rotate. The toothed ring 34 drives the third fixing body 310 to first rotate with the convex surface of the arc-shaped resin. At this time, the multi-stage electric telescopic rod 35 drives the third electric telescopic rod 38 to extend, so that the upper end of the heating plate 39 at the telescopic end of the third electric telescopic rod 38 is flush with the upper end of the resin. Then, the third electric telescopic rod 38 extends, driving the arc-shaped end of the heating plate 39 to contact the side surface of the resin. The second pressure sensor 315 at the telescopic end of the third electric telescopic rod 38 can ensure that the heating plate 39 just contacts the side surface of the resin. During the process of the fifth motor 33 driving the third fixing body 310 to rotate, the sixth motor 314 is started synchronously, and the sixth motor 314 is connected to the third electric telescopic rod 38 through a controller. The length of the arc-shaped surface of the arc-shaped resin can be calculated through the telescopic value of the third electric telescopic rod 38, so that the length of the isolation film rotated out from the side surface of the rotating rod 313 is the same as the arc length of the arc-shaped resin, ensuring that when the surface of the arc-shaped resin is covered with a film later, the gap between the isolation film and the surface of the arc-shaped resin is very small, preventing the gap between the isolation film and the resin from being too large and reducing the transportation volume of the resin after film covering.

[0041] After the fifth motor 33 drives the third fixed body 310 to rotate 360°, at this time, the worker first flattens and cuts the isolation film, and then fixes the end of the rotated isolation film at the initial position of the frame through a heat melter. At this time, the length of the isolation film on the side of the frame is the same as the length of the resin arc surface trajectory. Then the fifth motor 33 starts, driving the toothed ring 34 to rotate. At the same time, the third electric telescopic rod 38 expands and contracts according to the value of the second pressure sensor 315 at the end, ensuring that the heating plate 39 at the end of the second pressure sensor 315 contacts the resin surface. At the same time, the heating plate 39 is turned on to thermally shrink the side of the arc-shaped resin, preventing the resin surface from being subjected to a large pressure. When the side of the resin is completely shrunk, two first motors 25 are started. The two first motors 25 respectively drive the first threaded rod 26 to rotate, and the first threaded rod 26 cooperates to drive the first limiting body 24 to move. At the same time, the second motor 27 starts, and the second motor 27 drives the second threaded rod 29 to rotate. The second threaded rod 29 cooperates to drive the second limiting body 210 to move in the second limiting groove 28. The first motor 25 and the second motor 27 drive the second limiting body 210 to move along the trajectory drawn by the expansion and contraction of the third electric telescopic rod 38. While moving, the third motor 212 starts, and the third motor 212 rotates according to the side trajectory of the arc-shaped resin, so that the expansion and contraction direction of the double-axis electric telescopic rod 214 is always perpendicular to the side of the arc-shaped resin. The second electric telescopic rod 213 drives the two second fixed bodies 215 to move to the upper end of the isolation film. Then the double-axis electric telescopic rod 214 contracts, driving the two rollers 219 to contact the isolation film inward at the same time. Then the battery 218 drives the heating sheet 220 to heat, thereby thermally sealing the upper isolation film, so that the upper part of the arc-shaped resin is tightly covered with the film. When the film covering is completed, several fifth electric telescopic rods 45 are contracted, and the arc-shaped resin is rotated up and down and the steps are repeated, and the other end of the arc-shaped resin can be tightly sealed and covered with the film, improving the quality of the resin after sealing and covering with the film.
