Technical Field

[0001] This application relates to the technical field of balloon processing equipment, and in particular to a balloon stretching machine. Background Technology

[0002] Currently, commonly used balloons generally consist of a straight working section and tapered sections at both ends of the working section. The main steps in forming this type of balloon are: a tube blank is made from a thermoplastic material and inserted into the mold cavity; one end of the tube blank is clamped and sealed, while the other end is connected to the air source; the mold is heated using a heating element, and the tube blank inside the mold softens due to the heat; it is then pre-stretched by applying tension through a stretching device, followed by inflation; the mold is then cooled using a cooling system to set the balloon shape, and finally, the balloon is obtained.

[0003] One type of balloon stretching machine in the prior art, such as Figure 1 As shown, the device includes a base 1, two movable seats 11 slidably connected to the base 1 in opposite directions, two sets of clamping mechanisms 2 respectively installed on the two movable seats 11 for clamping the tube blank 12, a power module installed on the base 1 for driving the two movable seats 11 to slide in opposite directions, and a heating mechanism 3 installed between the two movable seats 11 for heating the tube blank 12; the power module and heating mechanism are common structures on mechanical equipment. During operation, the tube blank 12 is first placed after passing through the heating mechanism 3, then the two ends of the tube blank 12 are clamped and fixed by the two sets of clamping mechanisms 2, and then the tube blank 12 is heated by the heating mechanism 3. Next, the power module drives the two movable seats 11 to slide in opposite directions to axially stretch the tube blank 12. Finally, the stretched tube blank 12 is removed for further processing.

[0004] However, the above structure makes it inconvenient to cool the stretched tube blank 12 quickly, which will affect the processing efficiency of the balloon. Summary of the Invention

[0005] To facilitate rapid cooling of the stretched tube blank, this application provides a balloon stretching machine, employing the following technical solution: A balloon stretching machine includes a base, two movable seats slidably connected to the base in opposite directions or back-to-back, two sets of clamping mechanisms respectively installed on the two movable seats for clamping a tube blank, a power module installed on the base for driving the two movable seats to slide in opposite directions or back-to-back, and a heating mechanism installed between the two movable seats for heating the tube blank; the heating mechanism includes a heating frame, two heating seats slidably connected to the heating frame in opposite directions or back-to-back, and two heating cylinders installed on the heating frame for driving the two heating seats to move; two sets of cooling mechanisms for cooling the tube blank are installed on the base, the cooling mechanism includes a vertical plate installed on the base, a cooling frame installed on the top of the vertical plate, a blower hood installed on the bottom of the cooling frame, and a ring pump installed on the top of the blower hood; the air outlet of the ring pump is connected to the top of the blower hood.

[0006] By adopting the above technical solution, the tube blank is first placed after passing through two heating seats. Then, the two ends of the tube blank are clamped and fixed by two sets of clamping mechanisms. Subsequently, the tube blank is heated by the heating mechanism. Next, the power module drives the two moving seats to slide in opposite directions to stretch the tube body axially. When it is necessary to cool down the heated tube blank, the two heating seats are first driven to move in opposite directions by two heating cylinders to separate the two heating seats from the tube blank. Next, the air ring pump generates airflow through the blower hood, which can then rapidly cool the stretched tube blank. Finally, the clamping mechanisms are used to loosen the two ends of the tube blank, thus completing the stretching process. In summary, the cooling mechanism facilitates rapid cooling of the stretched tube blank.

[0007] Optionally, a first dust-blocking mechanism is installed at the bottom of the blower hood. The first dust-blocking mechanism includes two guide rings installed on the side wall of the blower hood, a first dust-blocking plate slidably connected to the two guide rings, and a driving component for driving the first dust-blocking plate to move.

[0008] By adopting the above technical solution, when the two heating cylinders drive the two heating seats to move in opposite directions to separate the two heating seats from the tube blank, the driving component drives the first dust baffle to move to open the opening of the blower hood, thereby facilitating the blower hood to cool the tube blank; the first dust baffle is set to block the opening of the blower hood, thereby reducing dust adhering to the inner wall of the blower hood.

[0009] Optionally, the driving assembly includes a vertical tube rotatably connected to the side wall of the cooling rack, a first gear sleeved and fixed to the outer side wall of the vertical tube, a first rack installed on the side wall of the first dust baffle and meshing with the first gear, and a vertical rod disposed inside the vertical tube; a plurality of spiral blocks are fixedly connected to the side wall of the vertical rod, and a plurality of spiral grooves corresponding one-to-one with the plurality of spiral blocks are provided on the inner wall of the vertical tube; a connecting rod is fixedly connected to the bottom of the vertical rod, and the end of the connecting rod away from the vertical rod is fixedly connected to one side of the heating seat; a first sliding sleeve is installed on the heating rack, and the vertical rod is slidably connected to the first sliding sleeve.

[0010] By adopting the above technical solution, the heating seat moves upward, driving the connecting rod to move upward. The connecting rod moves upward, driving the vertical rod to move upward. At this time, the vertical rod drives the vertical tube to rotate under the action of the spiral block and the spiral groove. The rotation of the vertical tube drives the first gear to rotate. The rotation of the first gear drives the first rack to move. The movement of the first rack can drive the first baffle plate to move. In summary, the driving component is designed to facilitate the movement of the first baffle plate.

[0011] Optionally, an air guiding mechanism for guiding air is installed on the vertical plate. The air guiding mechanism includes an air guiding plate hinged to the side wall of the vertical plate and a plurality of air guiding springs fixed between the air guiding plate and the vertical plate; a first rope is installed between the connecting rod and the air guiding plate.

[0012] By adopting the above technical solution, the connecting rod moves upward to drive the first rope to move, and the movement of the first rope drives the air guide plate to rotate towards the heating seat. At this time, the air guide plate and the opening of the blower cover form a certain inclination relationship, which facilitates further cooling of the tube blank.

[0013] Optionally, a waste gas treatment mechanism is installed on the base. The waste gas treatment mechanism includes a treatment box installed on the base, a negative pressure pump installed on the base, a first through hole opened in the side wall of the treatment box, and an activated carbon frame bolted to the first through hole. The air inlet of the negative pressure pump is connected to the bottom of the treatment box. The activated carbon frame is filled with activated carbon, and a support plate for supporting the activated carbon frame is installed on the side wall of the treatment box.

[0014] By adopting the above technical solution, when the blower hood cools the pipe body, the negative pressure pump is started first, and then the exhaust gas is sucked into the treatment box. After being treated by activated carbon adsorption in the activated carbon frame, the flow of harmful gases into the site can be reduced, thus facilitating the treatment of exhaust gas.

[0015] Optionally, the top of the treatment box is equipped with two sets of second dust-blocking mechanisms. Each set of second dust-blocking mechanisms includes a fixed frame fixed to one side of the treatment box, a horizontal rod slidably connected to the fixed frame, a second dust-blocking plate fixed to one end of the horizontal rod, and a dust-blocking spring sleeved on the horizontal rod. The two ends of the dust-blocking spring are respectively fixed to the inner sides of the second dust-blocking plate and the fixed frame. The two second dust-blocking plates are arranged corresponding to the two air guide plates. A second sliding sleeve is fixed to each of the two vertical plates. A moving rod is slidably connected in each of the second sliding sleeves. A second rope is installed between the two air guide plates and the top of the two moving rods. A pull rod is hinged between the bottom of the two moving rods and the two second dust-blocking plates.

[0016] By adopting the above technical solution, the rotation of the two air guide plates drives the movement of the two second ropes, which in turn drives the two moving rods to move upward. The upward movement of the two moving rods drives the two pull rods to move upward, and the upward movement of the two pull rods drives the two second ash baffles to move in opposite directions, thus facilitating the opening of the treatment box and enabling the treatment box to process the exhaust gas. When the two heating seats are reset under the action of the two heating cylinders, the two second ash baffles are also reset under the action of the ash baffle spring and the air guide spring, thus facilitating the shielding of the top of the treatment box and reducing the amount of dust entering the treatment box.

[0017] Optionally, a second through hole is provided on the side wall of the processing box, and a filter plate is obliquely bolted to the side wall of the processing box corresponding to the second through hole, and a plug is bolted into the second through hole.

[0018] By adopting the above technical solution, the filter plate can reduce the amount of dust entering the activated carbon frame; the plug facilitates the cleaning of debris flowing down the upper surface of the filter plate.

[0019] Optionally, the processing box is equipped with a vibration mechanism for vibrating the filter plate. The vibration mechanism includes a horizontal shaft rotatably connected to the side wall of the processing box, a rotating plate eccentrically connected to one end of the horizontal shaft, a third sliding sleeve fixed to the inner wall of the processing box, a vibration rod slidably connected to the third sliding sleeve and with one end abutting against the side wall of the rotating plate, a baffle fixed to the side wall of the vibration rod, and multiple vibration springs fixed between the baffle and the third sliding sleeve. The end of the vibration rod away from the rotating plate can abut against the bottom of the filter plate. A horizontal plate is fixed to the end of the moving rod away from the second dust baffle. A second rack is fixed to one side of the horizontal plate. A vertical shaft is rotatably connected to the bottom of the fixed frame. A second gear is sleeved and fixed on the vertical shaft. The second gear meshes with the second rack. A third bevel gear is fixed to the end of the vertical shaft away from the fixed frame. A fourth bevel gear is fixed to the end of the horizontal shaft away from the rotating plate. The third bevel gear meshes with the fourth bevel gear.

[0020] By adopting the above technical solution, the movement of the second baffle plate drives the movement of the moving rod, which in turn drives the movement of the horizontal plate, which in turn drives the movement of the second rack, which in turn drives the rotation of the second gear, which in turn drives the rotation of the vertical shaft, which in turn drives the rotation of the third bevel gear, which in turn drives the rotation of the fourth bevel gear, which in turn drives the rotation of the horizontal shaft, which in turn drives the rotation of the rotating plate. The rotation of the rotating plate, under the action of the vibration spring, can drive the vibration rod to move back and forth, thus vibrating the filter plate. This facilitates the rolling of debris on the upper surface of the filter plate into the second through hole, thereby improving the airflow efficiency of the filter plate.

[0021] Optionally, a damping hole is provided at one end of the horizontal plate near the processing box, and a damping rod is frictionally slidably connected inside the damping hole. A connecting spring and an abutment plate are respectively fixed to both ends of the damping rod. The abutment plate abuts against the outer wall of the processing box, and the end of the connecting spring away from the damping rod is fixed to the inner wall of one end of the damping hole.

[0022] By adopting the above technical solution, when the second ash baffle is reset, it is easy to buffer the second ash baffle under the action of the abutment plate, damping rod and connecting spring.

[0023] Optionally, each clamping mechanism includes a clamping frame fixed to the movable seat, a clamping cylinder mounted on the clamping frame, a movable clamping seat fixed to the piston rod of the clamping cylinder, and a fixed clamping seat fixed to the movable seat; the movable clamping seat and the fixed clamping seat are arranged opposite to each other for clamping the tube blank.

[0024] By adopting the above technical solution, the movable clamping seat and the fixed clamping seat are set up to facilitate the clamping of the tube blank.

[0025] In summary, this application includes at least one of the following beneficial technical effects: First, the tube blank is placed after passing through two heating seats. Then, two sets of clamping mechanisms clamp and fix both ends of the tube blank. Next, the heating mechanism heats the tube blank. Then, the power module drives the two moving seats to slide back and forth to axially stretch the tube body. When it is necessary to cool down the heated tube blank, the two heating cylinders drive the two heating seats to move back and forth to separate the two heating seats from the tube blank. Then, the air ring pump generates airflow through the blower hood, which can then quickly cool the stretched tube blank. Finally, the clamping mechanisms loosen both ends of the tube blank, thus completing the stretching process. In summary, the cooling mechanism facilitates rapid cooling of the stretched tube blank.

The limiting mechanism 4 includes a limiting frame 41 mounted on the base 1, two limiting seats 42 slidably connected to the limiting frame 41 in opposite directions, and two limiting cylinders 43 mounted on the limiting frame 41 for driving the two limiting seats 42 to move. The two limiting seats 42 facilitate vertical limiting of the tube body.

[0041] Reference Figures 2-4The base 1 is equipped with two cooling mechanisms 5 for cooling the tube blank 12. The cooling mechanism 5 includes a vertical plate 51 installed vertically on the base 1, a cooling rack 52 installed on the top of the vertical plate 51, a blower hood 53 installed at the bottom of the cooling rack 52, and an air ring pump 54 installed on the top of the blower hood 53. The bottom of the blower hood 53 has an opening, and the air outlet of the air ring pump 54 is connected to the top of the blower hood 53. First, the tube blank 12 is placed after passing through the two heating seats 32. Then, the two ends of the tube blank 12 are clamped and fixed by the movable clamping seat 23 and the fixed clamping seat 24. The tube blank 12 is then heated by the heating seats 32. Next, the two movable seats 11 are driven by the power module to slide in opposite directions to stretch the tube body axially. When it is necessary to cool down the heated tube blank 12, the two heating cylinders 33 are driven by the two heating seats 32 to move in opposite directions to separate the two heating seats 32 from the tube blank 12. Next, the air ring pump 54 generates airflow through the blower hood 53, which can then quickly cool the stretched tube blank 12. Finally, the two ends of the tube blank 12 are released by the movable clamping seat 23 and the fixed clamping seat 24, thus completing the stretching of the tube blank 12. In summary, the cooling mechanism 5 facilitates the rapid cooling of the stretched tube blank 12.

[0042] Reference Figure 3 and Figure 4 The bottom of the blower hood 53 is equipped with a first dust-blocking mechanism 6. The first dust-blocking mechanism 6 includes two guide rings 61 installed on the side wall of the blower hood 53, a first dust-blocking plate 62 that slides horizontally connected to the two guide rings 61, and a drive assembly for driving the first dust-blocking plate 62 to move.

The first dust-blocking plate 62 is provided to cover the opening of the blower hood 53, thereby reducing dust adhesion to the inner wall of the blower hood 53.

[0043] Reference Figures 3-5The drive assembly includes a vertical tube 63 vertically rotatably connected to the side wall of the cooling rack 52 via bearings, a first gear 631 sleeved and fixed to the outer side wall of the vertical tube 63, a first rack 64 installed on the side wall of the first dust baffle 62 and meshing with the first gear 631, and a vertical rod 65 vertically arranged inside the vertical tube 63; a plurality of spiral blocks 651 are fixedly connected to the side wall of the vertical rod 65, and a plurality of spiral grooves 632 corresponding one-to-one with the plurality of spiral blocks 651 are provided on the inner wall of the vertical tube 63; a connecting rod 66 is horizontally fixedly connected to the bottom of the vertical rod 65, and one end of the connecting rod 66 away from the vertical rod 65 is fixedly connected to one side of a heating seat 32, which is located above, and a first sliding sleeve 67 is installed on the heating rack 31, and the vertical rod 65 slides vertically and is connected to the first sliding sleeve 67. The heating base 32 moves upward, causing the connecting rod 66 to move upward. The connecting rod 66 moves upward, causing the vertical rod 65 to move upward. At this time, the vertical rod 65 drives the vertical tube 63 to rotate under the action of the spiral block 651 and the spiral groove 632. The rotation of the vertical tube 63 drives the first gear 631 to rotate. The rotation of the first gear 631 drives the first rack 64 to move. The movement of the first rack 64 can drive the first ash baffle 62 to move. In summary, the driving component is designed to facilitate the movement of the first ash baffle 62.

[0044] Reference Figure 3 and Figure 4 An air guiding mechanism 7 for guiding air is installed on the vertical plate 51. The air guiding mechanism 7 includes an air guiding plate 71 hinged to the side wall of the vertical plate 51 and multiple air guiding springs 72 fixed between the air guiding plate 71 and the vertical plate 51. A first rope 73 is installed between the connecting rod 66 and the air guiding plate 71. When the connecting rod 66 moves upward, it drives the first rope 73 to move. The movement of the first rope 73 drives the air guiding plate 71 to rotate towards the heating seat 32. At this time, the air guiding plate 71 and the opening of the blower hood 53 form a certain inclination relationship, which facilitates further cooling of the tube blank 12.

[0045] Reference Figure 2 , Figure 3 and Figure 6 A waste gas treatment mechanism 8 is installed on the base 1. The waste gas treatment mechanism 8 includes a treatment box 81 installed on the base 1, a negative pressure pump 82 installed on the base 1, a first through hole 811 opened in the side wall of the treatment box 81, and an activated carbon frame 83 bolted to the first through hole 811. The air inlet of the negative pressure pump 82 is connected to the bottom of the treatment box 81 through a pipe. The activated carbon frame 83 is filled with activated carbon, and a support plate 84 for supporting the activated carbon frame 83 is bolted to the side wall of the treatment box 81. When the blower hood 53 cools the pipe body, the negative pressure pump 82 is started first, and then the waste gas is drawn into the treatment box 81. After being adsorbed by the activated carbon in the activated carbon frame 83, the flow of harmful gases into the site can be reduced, thus facilitating the treatment of waste gas.

Each second sliding sleeve 95 is vertically connected to a moving rod 96. Springs can be installed to support the moving rod 96 as needed. A second rope 97 is installed between the top of the two air guide plates 71 and the top of the two moving rods 96. The bottom of the two moving rods 96 is hinged to the two second dust baffles 93. The bottom of the two moving rods 96 can also be connected to the two second dust baffles 93 by a flexible object such as a rope. The rotation of the two air guide plates 71 drives the movement of the two second ropes 97. The movement of the two second ropes 97 drives the two moving rods 96 to move upward. The upward movement of the two moving rods 96 drives the two pull rods 98 to move upward. The upward movement of the two pull rods 98 can drive the two second dust baffles 93 to move in opposite directions, thereby facilitating the opening of the treatment box 81 and making it easier for the treatment box 81 to treat the exhaust gas. When the two heating seats 32 are reset under the action of the two heating cylinders 33, the two second dust baffles 93 are reset under the action of the dust baffle spring 94 and the air guide spring 72, thereby facilitating the shielding of the top of the treatment box 81 and reducing the amount of dust entering the treatment box 81.

[0047] Reference Figure 6 The side wall of the treatment box 81 has a second through hole 812. A filter plate 85 is obliquely bolted to the side wall of the treatment box 81 corresponding to the second through hole 812 by bolts. A plug 86 is bolted into the second through hole 812 by bolts. The filter plate 85 reduces the amount of dust entering the activated carbon frame 83. The plug 86 facilitates the cleaning of debris flowing down the upper surface of the filter plate 85.

[0048] Reference Figure 6 and Figure 8The processing box 81 is equipped with a vibration mechanism 10 for vibrating the filter plate 85.

A second rack 1071 is horizontally fixed to one side of the horizontal plate 107. A vertical shaft 108 is vertically rotatably connected to the bottom of the fixed frame 91 via a bearing. A second gear 1081 is fixedly mounted on the vertical shaft 108 and meshes with the second rack 1071. A third bevel gear 1082 is fixed to the end of the vertical shaft 108 away from the fixed frame 91. A fourth bevel gear 1011 is fixed to the end of the horizontal shaft 101 away from the rotating plate 102 and meshes with the third bevel gear 1082 and the fourth bevel gear 1011. The movement of the second baffle plate 93 drives the movement of the moving rod 96, which in turn drives the movement of the horizontal plate 107. The movement of the horizontal plate 107 drives the movement of the second rack 1071, which in turn drives the rotation of the second gear 1081. The rotation of the second gear 1081 drives the rotation of the vertical shaft 108, which in turn drives the rotation of the third bevel gear 1082. The rotation of the third bevel gear 1082 drives the rotation of the fourth bevel gear 1011, which in turn drives the rotation of the horizontal shaft 101. The rotation of the horizontal shaft 101 drives the rotation of the rotating plate 102. The rotation of the rotating plate 102, under the action of the vibration spring 106, drives the vibration rod 104 to move back and forth. This vibrates the filter plate 85, making it easier for debris on the upper surface of the filter plate 85 to roll into the second through hole 812, thus improving the airflow efficiency of the filter plate 85.

[0049] Reference Figure 6 , Figure 8 and Figure 9 A damping hole 1072 is provided at one end of the horizontal plate 107 near the processing box 81. A damping rod 109 is frictionally slidably connected within the damping hole 1072 along the length of the horizontal plate 107. A connecting spring 1091 is horizontally fixed to both ends of the damping rod 109, and an abutment plate 1092 is vertically fixed to both ends. The abutment plate 1092 abuts against the outer wall of the processing box 81. The end of the connecting spring 1091 away from the damping rod 109 is fixed to the inner wall of one end of the damping hole 1072. When the second ash baffle 93 is reset, the abutment plate 1092, the damping rod 109, and the connecting spring 1091 facilitate buffering of the second ash baffle 93.
