Description

Technical Field

[0001] The utility model relates to the technical field of balloon production, in particular to a balloon mold rotating machine. Background Art

[0002] The balloon is formed on a mold by adding a vulcanizing agent to natural latex and then vulcanizing it. The mold is immersed in the prepared latex material, the latex material adheres to the mold, and then it is formed after subsequent heating, washing, flanging and demolding. Before the mold is immersed in the latex material, the surface of the mold needs to be cleaned to remove the remaining substances on the surface of the mold to improve the quality of the balloon surface and avoid impurities adhering to the balloon surface. The existing mold cleaning device uses water spraying for cleaning, and the cleaning effect is poor.

[0003] In order to improve the cleaning effect, existing balloon production lines often use rotating cleaning discs to clean the surface of balloon molds. The rotating cleaning surface of the cleaning disc is parallel to the conveying direction of the balloon conveyor frame, that is, multiple cleaning discs arranged at equal intervals rotate in the gap between adjacent balloon molds. The side wall bristles of the cleaning disc perform contact brushing and cleaning on the balloon mold. For example, a cleaning device for balloon production molds in the utility model patent with authorization announcement number CN216174742U adopts a similar mechanism. The original spray cleaning is converted to roller brush cleaning, and the friction of the roller brush removes the dirt on the mold surface, thereby achieving the purpose of thoroughly cleaning the mold surface.

[0004] However, the existing cleaning disc type cleaning device can only clean the surface wall of the balloon mold facing the cleaning disc. It cannot contact the bristles within a small angle range in front and behind the conveying direction of the balloon conveyor frame, resulting in a cleaning dead corner. In order to overcome this defect, it is necessary to manually rotate the balloon mold by a certain angle so that the next time the balloon mold reaches the cleaning disc type cleaning device, the dead corner can be thoroughly cleaned. The applicant's many years of experience in balloon production shows that in order to ensure the stable production of balloons with high quality, the mold must be manually adjusted at least once a week. It often takes a worker to work continuously for a day to complete the adjustment of all balloon molds on the entire continuously running production line. This wastes manpower seriously. At the same time, the operators need to look up and raise their hands for a long time to work, which is easy to fatigue and may also cause omissions.

[0005] Therefore, it is necessary to develop a balloon mold rotating machine for the above-mentioned defects. Utility Model Content

[0006] The utility model aims to provide a balloon mould rotating machine, which adopts a rubbing plate rubbing mode to realize online rotation of the balloon mould, has high operation efficiency and saves manpower.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

A plurality of washboards are arranged above the transmission box at intervals, and the washboards are arranged on the outside of each column of balloon molds, and two adjacent columns of balloon molds share one washboard. The transmission box can drive two adjacent washboards to rub the balloon mold so that the balloon mold rotates relative to a mounting sleeve.

[0009] Furthermore, a large gear and a small gear are provided in the transmission box, and a plurality of the large gears are arranged at equal intervals along the length direction of the transmission box, and two of the small gears are meshed and connected between two adjacent large gears at the front and rear; a vertical shaft is provided on the small gear protruding vertically upward, and an eccentric shaft head is provided on the top of the vertical shaft; the eccentric shaft head is inserted into the bottom of the washboard.

[0010] Furthermore, a bearing hole is provided at the bottom of the washboard, a bearing is provided in the bearing hole, and the eccentric shaft head is inserted into the inner ring of the bearing.

[0011] Furthermore, the washboard is a split structure, and telescopic holes are provided on the facing side walls of the front and rear half washboards, and a guide core shaft is slidably inserted into the telescopic holes.

[0012] Furthermore, a cushion layer made of a flexible material is provided on the side wall of the washboard in contact with the balloon mold, and the cushion layer is in rubbing contact with the outer wall of the balloon mold.

[0013] Furthermore, it also includes a lifting mechanism, which is arranged on the frame and can drive the transmission box to rise and fall horizontally.

[0014] Furthermore, the lifting mechanism includes a second reduction motor, a lead screw and a guide assembly, the guide assembly includes a guide column and a guide sleeve, the guide column is vertically arranged on the frame, the guide sleeve is arranged on both sides of the two ends of the transmission box, and the guide sleeve guides and slides on the guide column; the second reduction motor drives the vertically arranged lead screw to rotate, and nut sliders are arranged at both ends of the transmission box, and the nut slider transmission thread is connected to the lead screw.

[0015] Furthermore, it also includes a detection element, which is installed on the transmission box and can detect the movement of the washboard, and the detection element feeds back the detection signal to the control system of the second reduction motor.

[0016] Compared with the prior art, the beneficial technical effects of the utility model are:

[0017] The utility model discloses a balloon mold rotating machine. By arranging rubbing plates between the entire row of balloon molds and at the outermost sides, two adjacent rubbing plates rub the balloon mold in the middle under the drive of a transmission box, so that the balloon mold rotates. This inching rubbing method does not affect the continuous operation of the mold conveying frame, and replaces the manual rotation of the balloon mold. The utility model balloon mold rotating machine adopts the rubbing method of the rubbing plate to realize the online rotation of the balloon mold, which has high operating efficiency and saves manpower.

[0018] In addition, through the reasonable arrangement of the large gear and the small gear, the two small gears in front and behind the two adjacent large gears can realize synchronous and unidirectional operation, and the eccentric shaft head set at the top of the vertical shaft realizes the left and right and front and back movement of the washboard, which is manifested as the rubbing action of two adjacent washboards.

By setting a cushion layer on the side wall of the washboard, the balloon mold can be gently rubbed to avoid damage to the balloon mold. At the same time, it is more convenient to operate by replacing cushion layers of different thicknesses to adapt to balloon molds of different specifications. By setting the lifting mechanism, the horizontal rise and fall of the dynamic transmission box can be realized, that is, after completing the rotation of all balloon molds on the entire balloon production line, the transmission box is lowered, so that the washboard is separated from the balloon mold, and there is no need to run in unison, saving energy. At the same time, if the transmission box and the washboard part fail, they can be urgently lowered to separate from the balloon production line to avoid damage to the balloon mold caused by the washboard blocking part of the balloon mold. The lifting mechanism composed of the second reduction motor and the lead screw can stably drive the transmission box to move up and down, and is convenient for controlling the position accuracy in the height direction, so as to accurately adapt the height direction of different types of balloon molds.

[0030] Example 1

[0031] like Figures 1 to 5As shown, a balloon mold rotating machine is installed on a balloon production line. In the balloon production line, a mold conveying frame 11 is continuously operated and conveyed on a supporting beam frame 12, and multiple balloon molds 9 are conveyed in rows and columns below the mold conveying frame 11. The conveying direction along the mold conveying frame 11 is called a column, and the horizontal direction is called a row. The balloon mold 9 is installed on the mold conveying frame 11 through a mounting sleeve 10. The mounting sleeve 10 is made of a flexible material, and the neck of the balloon mold 9 can be slightly displaced relative to the mounting sleeve 10. The above-mentioned balloon production line is a prior art and therefore will not be described in detail. The utility model balloon mold rotating machine includes a frame 1, a transmission box 2 and a washboard 6. The transmission box 2 is horizontally arranged below the mold conveying frame 11, that is, the transmission box 2 is perpendicular to the conveying direction of the mold conveying frame 11. The two ends of the transmission box 2 are supported by the frame 1, and multiple washboards 6 are arranged above the transmission box 2 at intervals. Washboards 6 are arranged on the outside of each column of balloon molds 9, and two adjacent columns of balloon molds 9 share one washboard 6. In other words, the washboard 6 and the entire column of balloon molds 9 are arranged crosswise and at intervals. The transmission box 2 can drive two adjacent rubbing boards 6 to rub the balloon mold 9 so that the balloon mold 9 rotates relative to the mounting sleeve 10.

[0032] like Figure 5 As shown, the illustrated state is the instantaneous state of the washboard 6 rubbing the balloon mold 9. When the washboard 6 rubs the balloon mold 9, two adjacent washboards 6 approach the middle balloon mold 9, and the side walls of the washboards 6 contact the balloon mold 9. At the same time, one of the two washboards 6 moves forward and the other moves backward, so that the balloon mold 9 rotates relative to the mounting sleeve 10. Synchronously, the two washboards 6 also move outward, so that the other balloon molds 9 on both sides of the balloon mold 9 are also rubbed and rotated.

[0033] By arranging the rubbing plates 6 between the entire row of balloon molds 9 and at the outermost sides, two adjacent rubbing plates 6 rub the balloon mold 9 in the middle under the drive of the transmission box 2, so that the balloon mold 9 rotates. This inching rubbing method does not affect the continuous operation of the mold conveying frame 11, and replaces the manual rotation of the balloon mold 9. The utility model balloon mold rotating machine adopts the rubbing method of the rubbing plate to realize the online rotation of the balloon mold, which has high working efficiency and saves manpower.

[0034] In a specific implementation of this embodiment, Figure 3As shown, a large gear 4 and a small gear 5 are arranged in the transmission box 2, and a plurality of large gears 4 are arranged at equal intervals along the length direction of the transmission box 2, and two small gears 5 are meshed and connected between two adjacent large gears 4 at the front and rear. There are multiple large gears 4 and multiple small gears 5, and the specific number is adjusted according to the number of balloon molds 9 in a row on the balloon production line. The central axes of the large gear 4 and the small gear 5 are fixed to the bottom plate and the top plate of the transmission box 2 through bearings. The small gear 5 is vertically protruding upward and is provided with a vertical shaft 501, and the vertical shaft 501 protrudes out of the top plate of the transmission box 2, and an eccentric shaft head 502 is provided on the top of the vertical shaft 501. The eccentric shaft head 502 is inserted into the bottom of the washboard 6.

[0035] It should be noted that during installation, the eccentric shaft heads 502 need to be arranged in a staggered manner, that is, the eccentric shaft heads 502 at the top of the two vertical axes 501 of the washboard 6 here face forward, and the two eccentric shaft heads 502 of the next washboard 6 face backward, ensuring that the initial positions of the two are staggered.

[0036] Specifically, if Figure 3 and Figure 4 As shown, a bearing hole 601 is provided at the bottom of the washboard 6, a bearing 604 is arranged in the bearing hole 601, and the eccentric shaft head 502 is inserted into the inner ring of the bearing 604. The bearing 604 is specifically a deep groove ball bearing with a dustproof sealing cover.

[0037] Through the reasonable arrangement of the large gear 4 and the small gear 5, the two small gears 5 in front and behind between two adjacent large gears 4 can achieve synchronous and unidirectional operation. The eccentric shaft head 502 set at the top of the vertical shaft 501 realizes the left and right and front and back movement of the washboard 6, which is manifested externally as the rubbing action of two adjacent washboards 6.

[0038] Obviously, the transmission box 2 can also use a transmission mode of a rack driving the pinion 5 to drive the pinion 5 to rotate, and a linear drive unit is used to replace the first reduction motor 3 used to drive the large gear 4. The reciprocating linear motion rack can also realize the synchronous operation of the pinion 5. Similar simple deformation methods all fall within the protection scope of the utility model.

[0039] In a specific implementation of this embodiment, Figure 4 As shown, the washboard 6 is a split structure, and the front and rear half washboards are provided with telescopic holes 602 on the facing side walls, and a guide mandrel 603 is slidably inserted in the telescopic hole 602. Specifically, there are two guide mandrels 603 to ensure that the two half washboards do not misalign in height direction.

[0040] By setting the wash plate 6 as a split structure, the initial position deviation and operation deviation of the two eccentric shaft heads 502 caused by processing errors and cumulative installation errors can be bridged, ensuring that the eccentric shaft head 502 can normally drive the wash plate 6 to prevent jamming.

[0041] In a specific implementation of this embodiment, Figure 2 , Figure 4 and Figure 5 As shown, a cushion layer 606 made of a flexible material is provided on the side wall of the washboard 6 in contact with the balloon mold 9, and the cushion layer 606 is in rubbing contact with the outer wall of the balloon mold 9. The cushion layer 606 is a rubber plate with good flexibility or a foamed foam plate. The cushion layer 606 is installed on the side wall of the washboard 6 by connecting the mounting hole 605 with a countersunk bolt.

[0042] Obviously, the cushion layer 606 can also be installed on the side wall of the washboard 6 by bonding. At the same time, if the specifications of the balloon mold 9 on the balloon production line change, such as Change to When the rubbing board 6 or the cushion layer 606 is thicker, it can be selected to be replaced for adaptation.

[0043] By arranging the cushion layer 606 on the side wall of the washboard 6, the balloon mold 9 can be gently rubbed to avoid damage to the balloon mold 9. At the same time, it is more convenient to operate by replacing the cushion layer 606 of different thicknesses to adapt to balloon molds 9 of different specifications.

[0044] The working process of the balloon mold rotating machine of this embodiment: When working, the first reduction motor 3 drives the large gear 4 at the end to rotate, and all the large gears 4 and small gears 5 rotate. The small gear 5 drives the vertical shaft 501 to rotate, and the eccentric shaft head 502 at the top of the vertical shaft 501 makes a circle. The two eccentric shaft heads 502 at the front and back drive the washboard 6 to make regular movements left and right and front and back, which appear to the outside as the rubbing action of two adjacent washboards 6. The entire row of balloon molds 9 passes through the channel between two adjacent washboards 6 from front to back in sequence. During the transportation process, they are rubbed by the adjacent washboards 6 and rotated a certain angle relative to the mounting sleeve 10.

[0045] Example 2

[0046] On the basis of the above embodiment 1, a lifting mechanism is added, such as Figure 1 As shown, the lifting mechanism is arranged on the frame 1, and the lifting mechanism can drive the transmission box 2 to rise and fall horizontally.

[0047] By setting the lifting mechanism, the horizontal rise and fall of the dynamic transmission box 2 can be realized, that is, after completing the rotation of all balloon molds 9 on the entire balloon production line, the transmission box 2 is moved downward, so that the washboard 6 is separated from the balloon mold 9, and there is no need to run in unison, saving energy. At the same time, if the transmission box 2 and the washboard 6 partially fail, they can be urgently moved downward to separate from the balloon production line, avoiding damage to the balloon mold 9 caused by the washboard 6 blocking part of the balloon mold 9.

[0048] In a specific implementation of this embodiment, Figure 1As shown, the lifting mechanism includes a second reduction motor 7, a lead screw 8 and a guide assembly. The guide assembly includes a guide column 101 and a guide sleeve 201. The guide column 101 is vertically arranged on the frame 1, and the guide sleeve 201 is arranged on both sides of the two ends of the transmission box 2. The guide sleeve 201 guides and slides on the guide column 101. The guide sleeve 201 and the guide column 101 are used in conjunction with each other and are multiple sets. The second reduction motor 7 is installed at the bottom of the frame 1. The second reduction motor 7 drives the vertically arranged lead screw 8 to rotate. Nut sliders are arranged at both ends of the transmission box 2. The nut sliders are threaded to connect the lead screw 8. The number of the nut sliders and the lead screw 8 is two sets, which are respectively arranged at both ends of the transmission box 2. The gearboxes at the bottom of the two lead screws 8 can be connected by a transmission shaft to make them run synchronously. Two second reduction motors 7 can be used respectively, and the two second reduction motors 7 run synchronously through electrical control.

[0049] The lifting mechanism composed of the second reduction motor 7 and the lead screw 8 can stably drive the transmission box 2 to move up and down, and is convenient for controlling the position accuracy in the height direction, so as to accurately adapt different types of balloon molds 9 in the height direction.

[0050] Obviously, the lifting mechanism can also use a hydraulic cylinder, a gas cylinder or an electric push rod to achieve the vertical lifting action. Similar simple deformation methods all fall within the protection scope of the present utility model.

[0051] In a specific implementation of this embodiment, a detection element is further included. The detection element is installed on the transmission box 2 and can detect the movement of the washboard 6. The detection element feeds back the detection signal to the control system of the second reduction motor 7.

[0052] Specifically, the detection element is a centrifugal switch, which is installed on any one of the vertical shafts 501. The centrifugal switch transmits the speed signal of the vertical shaft 501 to the electronic control system. When it is detected that the speed of the vertical shaft 501 decreases, the electronic control system controls the second reduction motor 7 to start, and lowers the transmission box 2 to a safe position to avoid the situation where the washboard 6 collides with the balloon mold 9.

[0053] By providing the detection element to realize electrical closed-loop control, the transmission box 2 can be automatically lowered when a fault occurs, thereby avoiding collision damage to the mold.

[0054] The working process of the balloon mold rotating machine of this embodiment: when the rubbing component fails, the centrifugal switch transmits the speed signal of the vertical shaft 501 to the electronic control system. When it is detected that the speed of the vertical shaft 501 decreases, the electronic control system controls the second reduction motor 7 to start, driving the lead screws 8 at both ends to rotate synchronously, thereby driving the nut sliders at both ends of the transmission box 2 to move downward. Under the guidance of the guide sleeve 201 and the guide column 101, the transmission box 2 descends to a safe position to avoid the situation where the rubbing plate 6 collides with the balloon mold 9.

[0055] The utility model balloon mold rotating machine, by setting washboards 6 between the entire row of balloon molds 9 and at the outermost side, two adjacent washboards 6 rub the balloon mold 9 in the middle under the drive of the transmission box 2, so that the balloon mold 9 rotates. This inching rubbing method does not affect the continuous operation of the mold conveying frame 11, and replaces the manual rotation of the balloon mold 9. The utility model balloon mold rotating machine adopts the washboard rubbing method to realize the online rotation of the balloon mold, which has high working efficiency and saves manpower. In addition, through the reasonable arrangement and setting of the large gear 4 and the small gear 5, the front and rear small gears 5 between the two adjacent large gears 4 can realize synchronous and unidirectional operation, and the eccentric shaft head 502 set at the top of the vertical shaft 501 realizes the left and right and front and back movement of the washboard 6, which is externally manifested as the rubbing action of two adjacent washboards 6. By setting the washboard 6 as a split structure, the initial position deviation and operation deviation of the two eccentric shaft heads 502 caused by the processing error and the cumulative installation error can be bridged, and the eccentric shaft head 502 can be ensured to drive the washboard 6 normally to prevent jamming. By setting a cushion layer 606 on the side wall of the washboard 6, the balloon mold 9 can be gently rubbed to avoid damage to the balloon mold 9. At the same time, replacing cushion layers 606 of different thicknesses to adapt to balloon molds 9 of different specifications is more convenient to operate. By setting the lifting mechanism, the horizontal rise and fall of the dynamic transmission box 2 can be achieved, that is, after completing the rotation of all balloon molds 9 on the entire balloon production line, the transmission box 2 is moved downward so that the washboard 6 is separated from the balloon mold 9, and there is no need to run in unison, saving energy. At the same time, if the transmission box 2 and the washboard 6 partially fail, they can be urgently moved downward to separate from the balloon production line to avoid damage to the balloon mold 9 caused by the washboard 6 blocking part of the balloon mold 9. The lifting mechanism composed of the second reduction motor 7 and the lead screw 8 can stably drive the up and down lifting action of the transmission box 2, and it is convenient to control the position accuracy in the height direction, and accurately adapt different types of balloon molds 9 in the height direction. By setting the detection element to achieve electrical closed-loop control, the transmission box 2 can be automatically lowered in the event of a failure to avoid mold collision damage.
