[0043] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0044] As Figure 1 shown, it is a schematic structural diagram of a sandblasting machine for a capacitor core of the present invention. This sandblasting machine usually performs sandblasting on the surface of a cylindrical capacitor core to remove contaminants and defective layers on the surface of the capacitor core, and improve the surface quality and reliability of the capacitor core.

[0045] The sandblasting machine includes a material turning structure 1, a material pushing structure 2, a material pressing structure 3, and a sandblasting structure 4. The cylindrical capacitor core to be sandblasted is placed on the material turning structure 1. Under the combined action of the material pushing structure 2 and the material turning structure 1, the cylindrical capacitor core moves linearly towards the direction close to the sandblasting station while rotating around its own axis, and the surface is sandblasted by passing through the sandblasting gun 407 during the rotation + movement process.

[0046] The sandblasting structure 4 is arranged on one side of the material turning structure 1, and sandblasting glass beads are ejected by the sandblasting structure 4 to complete the sandblasting work on the surface of the capacitor core. When sandblasting, the material pressing structure 3 descends and presses against the top of the capacitor core to prevent the capacitor core from falling off the material turning structure 1 during sandblasting.

[0047] As Figure 2 shown, it is a schematic structural diagram of the material turning structure 1. The material turning structure 1 includes a first support frame, a material turning frame 101, material turning rollers, a first lifting mechanism, etc. (Specifically, during sandblasting, the sandblasting gun 407 will eject sandblasting glass beads. To avoid the sandblasting glass beads flying everywhere and endangering the safety of surrounding staff, the entire sandblasting process is completed inside the control box. The control box is welded into a box structure by aluminum profiles and metal plates, and its interior is hollow. The material turning structure 1, the material pushing structure 2, the material pressing structure 3, and the sandblasting structure 4 are all arranged inside the control box, and the sandblasting direction of the sandblasting structure 4 is towards the material turning structure 1).

[0048] The first support frame is fixed on the top of the control box. The first support frame mainly plays a role of supporting and fixing. As Figure 5 shown, the first support frame includes a first lower support plate 114, a first column 116, and a first upper support plate 115. The first lower support plate 114 is fixed on the top of the control box by means of screw fastening. There are at least two first columns 116, which are fixed on the top of the first lower support plate 114 by welding and are arranged at intervals. The spaced arrangement of the first columns 116 provides an avoidance space for the installation of the first lifting plate 119.

[0049] The first upper support plate 115 is fixed to the top of the first column 116 by welding. The first lower guide sleeve 117 is embedded in the first lower support plate 114, and the first upper guide sleeve 118 is embedded in the first upper support plate 115. The first guide rod 113 passes through the first upper guide sleeve 118 and the first lower guide sleeve 117 and extends into the control box (a through groove is provided at the top of the control box, and the size of the through groove is smaller than the size of the first lower support plate 114, which can not only meet the fixation of the first lower support plate 114, but also allow the first guide rod 113 to pass through the control box and extend into the interior of the control box).

[0050] Both ends of the first lead screw 120 are respectively installed on the first lower support plate 114 and the first upper support plate 115 through bearings, and the first lead screw 120 is vertically arranged (that is, the first lead screw 120 is parallel to the first guide rod 113). The first lifting plate 119 is fixed on the first guide rod 113 and cooperates with the first lead screw 120 (specifically, a through hole matching the first guide rod 113 is provided on the first lifting plate 119, the first guide rod 113 passes through the through hole of the first lifting plate 119, and then the first lifting plate 119 and the first guide rod 113 are fixed together by welding; a lead screw nut is arranged on the first lead screw 120, and the lead screw nut is fixed on the first lifting plate 119 by screw fastening).

[0051] When the first lead screw 120 rotates, it will drive the first lifting plate 119 to move up and down. Furthermore, the first lifting plate 119 drives the first guide rod 113 to move up and down, and finally drives the turnover rack 101 at the bottom of the first guide rod 113 to move up and down. The turnover rack 101 drives the cylindrical capacitor cores thereon to move up and down to meet the surface sandblasting treatment of capacitor cores with different diameters (when switching capacitor cores with different diameters, it can also ensure that the centers of the cores are on the same center line, improving the sandblasting effect). By providing the first lower guide sleeve 117 and the first upper guide sleeve 118 that cooperate with the first guide rod 113, the lifting movement of the first guide rod 113 is guided to improve the stability of its lifting.

[0052] The third gear 128 is sleeved on the top of the first lead screw 120 by key connection, and the third synchronous belt 129 is wound around the third gear 128. To ensure the smooth lifting movement of the turnover rack 101, a set of first support frames (that is, two first support frames, jointly lifting the turnover rack 101) needs to be provided. When the driving unit drives the first lead screw 120 to rotate, the power is transmitted to another set of first support frames by the third gear 128 and the third synchronous belt 129, and then drives the first lead screw 120 on another set of first support frames to rotate synchronously.

[0053] To prevent slipping between the third gear 128 and the third synchronous belt 129, which may cause asynchronous movement of the first lead screws 120 on both sides, the third synchronous belt 129 is selected as a toothed belt, and the third gear 128 is selected as a synchronous pulley (a synchronous pulley is a part with equally spaced serrated gears on its outer peripheral surface, which can mesh with the tooth grooves of the toothed belt to transmit motion and power and prevent slipping).

[0054] The pressing plate 130 is fixed to the top of the first upper support plate 115 by means of screws or welding. The inner support plate 131 is fixed to the side of the pressing plate 130 close to the third synchronous belt 129. The roller 132 is rotatably installed between the pressing plate 130 and the inner support plate 131 and abuts against the outer side of the third synchronous belt 129 to improve the rotational stability of the third synchronous belt 129 (specifically, the rotating shaft passes through the roller 132 in an interference fit manner and is coaxially arranged with the roller 132. Both ends of the rotating shaft are respectively installed between the pressing plate 130 and the inner support plate 131 through bearings. When the third synchronous belt 129 rotates, it drives the roller 132 to rotate synchronously under the action of friction).

[0055] The first extension plate 121 is fixed to one side of the first upper support plate 115 by means of welding or screw fastening. The first adjusting plate 122 is adjustably fixed to the top of the first extension plate 121 (specifically, a through adjusting groove 123 is formed on the first adjusting plate 122. The adjusting groove 123 is in the shape of a rounded rectangle. The fastening bolt passes through the adjusting groove 123 and is fixed to the top of the first extension plate 121). A through groove penetrates the first extension plate 121. The second motor 124 is fixed to the bottom of the first adjusting plate 122 by means of screw fastening. By providing a through groove on the first extension plate 121, an avoidance space is provided for the installation of the second motor 124. By adjusting the position of the first adjusting plate 122, the position of the second motor 124 can be appropriately adjusted outwards, thereby tensioning the drive belt 127.

[0056] The small gear 125 is fixed to the motor shaft of the second motor 124 by key connection. The large gear 126 is fixed to the first lead screw 120 by key connection. The drive belt 127 is wound around the small gear 125 and the large gear 126. The second motor 124 drives the small gear 125 to rotate, and the drive belt 127 drives the large gear 126 to rotate, thereby driving the first lead screw 120 to rotate.

[0057] The diameter of the small gear 125 is smaller than that of the large gear 126 to reduce the rotational speed of the first lead screw 120, thereby reducing the lifting speed of the tipping frame 101 and improving the stability of the lifting movement.

[0058] To avoid slippage between the pinion 125, the large gear 126 and the drive belt 127, the drive belt 127 is selected as a toothed belt, and the large gear 126 and the pinion 125 are selected as synchronous belt pulleys (a synchronous belt pulley is a part with equally spaced serrated gears on its outer peripheral surface, which can mesh with the tooth grooves of the toothed belt to transmit motion and power and avoid slippage).

[0059] The fixing frame 112 is fixed to the bottom of the first guide rod 113 by means of screws, and the tipping frame 101 is fixed to the bottom of the fixing frame 112 by means of screws. When the first lifting mechanism drives the first guide rod 113 to lift and lower, it will drive the tipping frame 101 and the cylindrical capacitor cores thereon to lift and lower synchronously (the first support frame is fixed to the top of the control box, so the first support frame is located outside the control box, while the first guide rod 113 and the tipping frame 101 are placed inside the control box).

[0060] There are two tipping rollers, and the two ends are respectively rotatably installed on the tipping frame 101 through bearings (specifically, the two tipping rollers are arranged in parallel, and the cylindrical capacitor cores to be sandblasted are placed on the two tipping rollers. The circumferential surface of the cylindrical capacitor core abuts against the tipping roller. When the tipping roller rotates, it drives the cylindrical capacitor core to rotate, and then the outer peripheral surface of the cylindrical capacitor core is sandblasted by the sandblasting gun 407 on one side. When sandblasting, the cylindrical capacitor core is rotated to avoid sandblasting blind spots and improve the sandblasting effect).

[0061] As Figure 3 shown, each tipping roller is formed by sequentially inserting a plurality of inserting rods 102. An inserting groove 103 is opened at one end of the inserting rod 102, and an inserting portion 104 is integrally connected to the other end of the inserting rod 102 and is matched with the inserting groove 103. The inserting portions 104 of adjacent two inserting rods 102 are inserted into the inserting grooves 103 with each other, so the tipping roller is formed by mutually inserting a plurality of inserting rods 102.

[0062] The sleeve 106 is fixed to the inside of the tipping frame 101 through a fixing plate, and the inserting parts of adjacent two inserting rods 102 are inserted into the sleeve 106. The sleeve 106 supports the inserting parts to prevent the inserting parts from being misaligned and scattered when the inserting rod 102 rotates.

[0063] The tipping roller is composed of inserting a plurality of inserting rods 102, and the sleeve 106 is used to improve the structural strength of the inserting rod 102. By shortening the length of a single inserting rod 102, it is avoided that the middle part of the inserting rod 102 sags downward under the action of gravity, which affects the flipping of the cylindrical capacitor core. The bearing sleeve 105 is press-fitted on the inserting rod 102 and the outer diameter of the bearing sleeve 105 is equal to the outer diameter of the sleeve 106, which is convenient for the forward pushing of the cylindrical capacitor core (if the outer diameters of the bearing sleeve 105 and the sleeve 106 do not match, the cylindrical capacitor core will be stuck when pushed forward).

[0064] When the insertion rod 102 rotates, it will drive the bearing sleeve 105 to rotate synchronously, thereby flipping the cylindrical capacitor core on it. The sleeve 106 does not rotate, and the connection part of two adjacent insertion rods 102 is supported by the sleeve 106 (to improve the stability of rotation, bearings are installed on both sides inside the sleeve 106, and the two ends of two adjacent insertion rods 102 are respectively inserted into the bearings of the sleeve 106 and then inserted together).

[0065] As Figure 4 shown, the first gear 108 is fixed to one end of the insertion rod 102 by key connection. The first synchronous belt 109 is wound around the first gear 108. By setting the first gear 108 and the first synchronous belt 109, the same-direction rotation of the insertion rod 102 is realized. To prevent slipping between the first gear 108 and the first synchronous belt 109, the first synchronous belt 109 is selected as a toothed belt, and the first gear 108 is selected as a synchronous pulley (a synchronous pulley is a part with equally spaced serrated gears on its outer peripheral surface, which can mesh with the tooth grooves of the toothed belt to transmit motion and power and prevent slipping).

[0066] The first motor 107 is fixed to one side of the material turning frame 101 by a metal plate (specifically, the metal plate is fixed to one side of the material turning frame 101 by screwing or welding, and the motor housing of the first motor 107 is fixed to the metal plate by screwing). The motor shaft of the first motor 107 passes through the metal plate. The second gear 110 is fixed to the motor shaft of the first motor 107 and one end of the insertion rod 102 by key connection. The second synchronous belt 111 is wound around the second gear 110. By driving the second gear 110 to rotate by the first motor 107, the two material turning rollers are driven to rotate, so as to rotate the cylindrical capacitor core on them, and finally the sandblasting gun 407 on one side completes the sandblasting treatment on the surface of the capacitor core.

[0067] To prevent slipping between the second gear 110 and the second synchronous belt 111, the second synchronous belt 111 is selected as a toothed belt, and the second gear 110 is selected as a synchronous pulley (a synchronous pulley is a part with equally spaced serrated gears on its outer peripheral surface, which can mesh with the tooth grooves of the toothed belt to transmit motion and power and prevent slipping).

[0068] The material pushing structure 2 is fixed in the control box and is located below the material turning frame 101, and is used to push the axially rotating capacitor core to the sandblasting station for sandblasting treatment. As Figure 6 、 7 shown, the material pushing structure 2 includes a material pushing frame 201, a material pushing belt 212, a material pushing component, a limiting component and an adjusting component. The material pushing frame 201 is fixed in the control box by aluminum profiles and is located below the material turning frame 101 (specifically, the aluminum profiles are fixed to the bottom inside the control box by welding, and the material pushing frame 201 is fixed to the top of the aluminum profiles by screwing).

[0069] The first material pushing wheel 203 is rotatably installed on one side of the material pushing frame 201 (specifically, a wheel shaft is fixed to the first material pushing wheel 203 by key connection, and both ends of the wheel shaft are respectively installed on one side of the material pushing frame 201 through bearings). The third motor 202 is fixed to one side of the material pushing frame 201 (specifically, the support frame is fixed to the bottom inside the control box by welding, the motor housing of the third motor 202 is fixed to the top of the support frame by screw fastening, and the output shaft of the third motor 202 is connected to the wheel shaft on the first material pushing wheel 203 through a coupling. The third motor 202 drives the first material pushing wheel 203 to rotate, and then drives the material pushing belt 212 on the first material pushing wheel 203 to rotate, so as to push the capacitor cores on the turning roller towards the sandblasting station).

[0070] The second material pushing wheel 207 is installed on the other side of the material pushing frame 201 through an adjusting component (that is, the second material pushing wheel 207 is installed on the side of the material pushing frame 201 away from the first material pushing wheel 203), as Figure 9 shown. The adjusting component includes a sliding plate 204, a sliding groove 205, a second adjusting plate 206, a second material pushing wheel 207, a resisting plate 208, a locking plate 209, an adjusting bolt 210 and an adjusting nut 211. The sliding plate 204 is fixed to the outside of the material pushing frame 201 by screw fastening, and the sliding groove 205 is opened on the opposite side of the sliding plate 204 (that is, the sliding groove 205 is opened on the inside of the sliding plate 204).

[0071] The second adjusting plate 206 is inserted into the sliding grooves 205 of the two sliding plates 204, and the second adjusting plate 206 is supported and limited by the sliding plate 204 to ensure that the second adjusting plate 206 can only be adjusted horizontally. The second material pushing wheel 207 is rotatably installed on the second adjusting plate 206 (specifically, a wheel shaft is fixed to the second material pushing wheel 207 by key connection, and both ends of the wheel shaft are respectively installed between the second adjusting plates 206 through bearings). By moving the second adjusting plate 206 outwards, the material pushing belt 212 on the first material pushing wheel 203 and the second material pushing wheel 207 is tensioned to prevent the material pushing belt 212 from loosening and slipping due to deformation during long-term use.

[0072] To prevent slipping between the first material pushing wheel 203, the second material pushing wheel 207 and the material pushing belt 212, the material pushing belt 212 is selected as a toothed belt, and the first material pushing wheel 203 and the second material pushing wheel 207 are selected as synchronous belt pulleys (a synchronous belt pulley is a part with equally spaced serrated gears on its outer peripheral surface, which can mesh with the tooth grooves of the toothed belt to transmit motion and power and prevent slipping).

[0073] The support plate 208 is fixed to the side of the pusher rack 201 close to the second adjustment plate 206 by screwing, and the locking plate 209 is fixed to the second adjustment plate 206 by screwing. A threaded hole is provided on the locking plate 209, and the adjusting bolt 210 is screwed through the threaded hole on the locking plate 209 and abuts against one side of the support plate 208 (the adjusting bolt 210 and the support plate 208 are not fixedly connected, but simply abut against each other).

[0074] The adjusting nut 211 is screwed onto the adjusting bolt 210 and abuts against the side of the locking plate 209 away from the abutting plate 208, thereby locking the adjusted adjusting nut 211. During actual adjustment, first pull the second adjusting plate 206 outward until the pushing belt 212 is tightened (under the action of the slide plate 204 and the slide groove 205, the second adjusting plate 206 can only be adjusted outward horizontally), then screw the adjusting bolt 210 until it abuts against one side of the abutting plate 208, and screw the adjusting nut 211 until it abuts against the side of the locking plate 209.

[0075] The protrusion 213 is integrally connected to the outer side of the pushing belt 212, and the pushing assembly is fixed on the protrusion 213. When the pushing belt 212 rotates, the protrusion 213 will be driven to rotate synchronously, thereby driving the pushing assembly to rotate. The pushing assembly rotates to the top of the pushing belt 212, and the pushing assembly is in a horizontal motion state. At this time, the pushing assembly pushes the capacitor core on the turning roller forward to the sandblasting station.

[0076] like Figure 12 , 13 As shown, the pusher assembly includes a limit plate 214, an insert block 215, a fixing groove 216, a pusher rod 217, a cam bearing follower 218, a cover 219 and a follower sleeve 220. The insert block 215 is integrally connected to the bottom of the limit plate 214, and the fixing groove 216 is provided in the insert block 215 and matched with the protrusion 213. During actual installation, the fixing groove 216 is inserted into the protrusion 213 outside the pusher belt 212, and then the limit plate 214 is fixed to the protrusion 213 by screw fastening.

[0077] The protrusion 213 is a rectangular block, and the length direction of the protrusion 213 is parallel to the width direction of the pushing belt 212. Therefore, when the limiting plate 214 is fixed on the protrusion 213, the length direction of the fixing groove 216 is also parallel to the width direction of the pushing belt 212. When the pushing belt 212 drives the protrusion 213 to rotate, the protrusion 213 will press against the limiting plate 214, and then drive the limiting plate 214 to rotate synchronously with it, thereby improving the reliability and timeliness of the pushing position of the capacitor core.

[0078] The pusher rod 217 is fixed on the side of the limit plate 214 away from the insertion block 215, and the cam follower 218 is fixed on the side of the pusher rod 217 away from the limit plate 214. The cam follower 218 is of the commercially available CFUA6-16 model. The follower sleeve 220 is sleeved on the cam follower 218 and is coaxially arranged with the capacitor core (specifically, the follower sleeve 220 is press-fitted on the roller of the cam follower 218 to ensure that the follower sleeve 220 can rotate coaxially with the rotation of the capacitor core). The capacitor core is in an axial rotation state under the action of the turning roller. When the follower sleeve 220 abuts against the capacitor core and moves forward, under the action of friction, the capacitor core will drive the follower sleeve 220 to rotate synchronously.

[0079] If the follower sleeve 220 is fixed or not coaxially arranged with the capacitor core, when it abuts against the side of the axially rotating capacitor core, the capacitor core is likely to jump on the turning roller or fall off the turning roller.

[0080] The housing 219 is fixed on the pusher rod 217 and covers the nut side of the cam follower 218 to prevent moisture or corrosive substances from entering, thus playing an anti-rust role and improving the service life of the cam follower 218.

[0081] The limit assembly is fixed inside the pusher frame 201 and is used to support the limit plate 214 during rotation. When the pusher assembly pushes the capacitor core forward, it can prevent the pusher belt 212 from being deformed under the action of gravity. As Figure 10 、 11 shown, the limit assembly includes a fixing plate 221, a first slot 222, a first avoidance groove 223, a second slot 224, a second avoidance groove 225, a first limit rod 226, a limit groove 227, a second limit rod 228 and a guiding part 229. The fixing plate 221 is fixed inside the pusher frame 201 by means of screw fastening. The first slot 222 horizontally penetrates the fixing plate 221 and is located above the pusher belt 212. The first avoidance groove 223 horizontally penetrates the fixing plate 221 and is connected to the first slot 222. When the pusher belt 212 drives the pusher assembly to move to push the capacitor core, it can avoid the position of the limit plate 214 through the first avoidance groove 223.

[0082] Arc-shaped first insertion parts are formed on the upper and lower sides of the first slot 222, and the central angle of the arc of the first insertion part is greater than 180°. Therefore, when the first limit rod 226 is horizontally inserted into the first insertion parts on both sides of the first slot 222, the arc-shaped first insertion part will clamp the first limit rod 226 and prevent it from falling out of the first insertion part.

[0083] The limiting groove 227 is formed between the two first limiting rods 226, and the height of the limiting plate 214 is equal to the height of the limiting groove 227. By providing two first limiting rods 226, when the pushing belt 212 drives the pushing assembly to move to push the capacitor core, the limiting plate 214 is placed in the limiting groove 227, and the limiting plate 214 is supported upward by the first limiting rod 226 below, so as to prevent the gravity of the limiting assembly from directly acting on the pushing belt 212, which will deform the pushing belt 212 and affect the position accuracy of the capacitor core.

[0084] At the same time, the first limiting rod 226 at the top is pressed on the top of the limiting plate 214. When sandblasting, the sandblasting gun 407 will spray sandblasting glass beads to one side of the capacitor core, and the sandblasting glass beads are easy to hit the limiting component (the limiting component will swing toward the side away from the sandblasting gun 407 due to the force. Since the limiting component is fixed on the pushing belt 212, it will cause the pushing belt 212 to twist and deform, thereby affecting the pushing of the capacitor core). Under the pressure of the first limiting rod 226 at the top, the limiting component is prevented from tilting toward the side away from the sandblasting gun, causing the pushing belt 212 to deform or push the capacitor core down.

[0085] The second slot 224 horizontally penetrates the fixed plate 221 and is located below the pushing belt 212. The second avoidance slot 225 penetrates the fixed plate 221 and is connected to the second slot 224. After the pushing belt 212 drives the pushing assembly to move and push the capacitor core, when the pushing belt 212 circulates, it will drive the pushing assembly to rotate to the bottom of the pushing belt 212. At this time, the first avoidance slot 223 is used to avoid the position of the limit plate 214.

[0086] An arc-shaped second plug-in portion is formed at the bottom of the second slot 224, and the arc center angle of the second plug-in portion is greater than 180°. Therefore, when the second limiting rod 228 is horizontally inserted into the second plug-in portion at the bottom of the second slot 224, the arc-shaped second plug-in portion will clamp the second limiting rod 228, preventing it from escaping from the second plug-in portion.

[0087] When the pushing belt 212 drives the pushing assembly to circulate, the pushing assembly rotates to the bottom of the pushing belt 212. Under the action of gravity, the pushing assembly will pull the pushing belt 212 downward, causing the pushing belt 212 to deform. Therefore, the limiting plate 214 is supported by the second limiting rod 228 (only one second limiting rod 228 is needed during circulation, because the circulation position is below the pushing belt 212, and the sandblasting glass beads sprayed by the sandblasting gun 407 will not act on the pushing assembly here, so there is no need to set additional limiting rods).

[0088] The guide portion 229 is obliquely disposed at both ends of the first limiting rod 226 and the second limiting rod 228 , so as to facilitate the limiting plate 214 to rotate into the limiting groove 227 or onto the second limiting rod 228 .

[0089] As shown Figure 14 in FIG. Figure 14 , it is a schematic structural diagram of the blank holding structure 3. The blank holding structure 3 is arranged above the material turning structure 1. During sandblasting, it is pressed on the surface of the cylindrical capacitor core by the blank holding structure 3 to prevent the capacitor core from falling off the material turning roller when it is flipped. The blank holding structure 3 includes a second support frame, a second lifting mechanism, a pressing rod 313, etc. The second support frame is fixed on the top of the control box, mainly playing a role of support and fixation. The second support frame includes a second lower support plate 301, second columns 303 and a second upper support plate 302. The second lower support plate 301 is fixed on the top of the control box by means of screw fastening. There are at least two second columns 303, which are fixed on the top of the second lower support plate 301 by welding and are arranged at intervals. The interval setting of the second columns 303 provides an avoidance space for the installation of the second lifting plate 306.

[0090] The second upper support plate 302 is fixed on the top of the second columns 303 by welding. The second lower guide sleeve 304 is embedded in the second lower support plate 301, and the second upper guide sleeve 305 is embedded in the second upper support plate 302. The second guide rod 309 passes through the second upper guide sleeve 305 and the second lower guide sleeve 304 and extends into the control box (a through groove is opened at the top of the control box, and the size of the through groove is smaller than the size of the second lower support plate 301, which can not only meet the fixation of the second lower support plate 301, but also enable the second guide rod 309 to pass through the control box and extend into the interior of the control box).

[0091] Both ends of the second lead screw 307 are respectively installed on the second lower support plate 301 and the second upper support plate 302 through bearings, and the second lead screw 307 is vertically arranged (that is, the second lead screw 307 is parallel to the second guide rod 309). The second lifting plate 306 is fixed on the second guide rod 309 and is matched with the second lead screw 307 (specifically, a through hole matched with the second guide rod 309 is opened on the second lifting plate 306, the second guide rod 309 passes through the through hole of the second lifting plate 306, and then the second lifting plate 306 and the second guide rod 309 are fixed together by welding; a lead screw nut is arranged on the second lead screw 307, and the lead screw nut is fixed on the second lifting plate 306 by means of screw fastening).

[0092] When the second lead screw 307 rotates, it will drive the second lifting plate 306 to move up and down. Furthermore, the second lifting plate 306 will drive the second guide rod 309 to move up and down, and finally drive the pressing rod 313 at the bottom of the second guide rod 309 to move up and down. The pressing rod 313 presses on the surface of the cylindrical capacitor core to prevent it from falling during rotary sandblasting.

[0093] The fourth motor 308 is fixed to the top of the second upper support plate 302 by means of screw fastening. The output shaft of the fourth motor 308 is connected to the second lead screw 307, and the second lead screw 307 is driven to rotate by the fourth motor 308 (the second support frame is fixed to the top of the control box, so the second support frame is located outside the control box, while the second guide rod 309 and the pressing rod 313 are placed inside the control box).

[0094] A second extension plate 310 is fixed to the bottom of the second guide rod 309, and the second extension plate 310 extends toward the side close to the tipping frame 101 to ensure that the pressing rod 313 can press directly above the cylindrical capacitor core. A fixing column 311 is fixed to the side of the second extension plate 310 away from the second guide rod 309. Fixing blocks 312 are fixed to both ends of the fixing column 311, and both ends of the pressing rod 313 are rotatably mounted at the bottom of the fixing blocks 312 through bearings.

[0095] When the sandblasting gun 407 sandblasts the surface of the cylindrical capacitor core, the pressing rod 313 descends and abuts against the surface of the cylindrical capacitor core. When the cylindrical capacitor core rotates, it drives the pressing rod 313 to rotate under the action of friction. Under the action of the pressing rod 313, the cylindrical capacitor core is prevented from falling.

[0096] The sandblasting structure 4 is fixed to the bottom inside the control box and is located on one side of the tipping frame 101 to sandblast the peripheral surface of the capacitor core. The sandblasting structure 4 includes a sandblasting frame 401, a sandblasting bearing 402, a sandblasting guide post 403, a sandblasting lead screw 404, a sandblasting moving plate 405, a sandblasting motor 406, and a sandblasting gun 407. The sandblasting frame 401 is fixed to the bottom inside the control box by means of screw fastening. The sandblasting bearing 402 is installed inside the sandblasting frame 401 and is horizontally arranged. The sandblasting guide post 403 is inserted into the sandblasting bearing 402, and a sandblasting gun 407 is fixed to the side of the sandblasting guide post 403 close to the tipping frame 101. The sandblasting glass beads are sprayed onto the capacitor core through the sandblasting gun 407.

[0097] Both ends of the sandblasting lead screw 404 are rotatably mounted inside the sandblasting frame 401. The sandblasting motor 406 is fixed to the sandblasting frame 401 by means of screw fastening and is connected to the sandblasting lead screw 404. The sandblasting lead screw 404 is driven to rotate by the sandblasting motor 406.

[0098] The sandblasting moving plate 405 is connected to the sandblasting guide post 403 and is fixed to the sandblasting lead screw 404 (specifically, through holes matching the sandblasting guide post 403 are provided on the sandblasting moving plate 405. The sandblasting guide post 403 passes through the through holes of the sandblasting moving plate 405, and then the sandblasting moving plate 405 and the sandblasting guide post 403 are fixed together by welding; a lead screw nut is arranged in cooperation with the sandblasting lead screw 404, and the lead screw nut is fixed to the sandblasting moving plate 405 by means of screw fastening).

[0099] The sandblasting motor 406 drives the sandblasting gun 407 to move closer to or away from the capacitor core, thereby achieving different degrees of sandblasting effects and improving the versatility of the equipment.

[0100] The turnover structure 1 is suspended inside the control box through a set of first support frames, and the turnover frame 101 extends horizontally outward to the outside of the control box, facilitating the feeding of cylindrical capacitor cores. The pressing structure 3 is suspended inside the control box through the second support frame and is located above the turnover structure 1. The pushing structure 2 is fixed to the bottom inside the control box and is located below the turnover structure 1, and the sandblasting structure is fixed to the bottom inside the control box and is located on one side of the turnover structure 1.

[0101] During sandblasting, the capacitor core is placed on the turnover roller, and the turnover roller drives the capacitor core to rotate axially. At the same time, the pushing belt 212 drives the pushing component to rotate, and the pushing component pushes the axially rotating capacitor core forward (during this process, the follower sleeve 220 is coaxially arranged with the capacitor core, and the follower sleeve 220 presses against the capacitor core and moves it forward). When it moves to the sandblasting station, the pressing structure 3 descends and the pressing rod 313 presses against the outer peripheral surface of the capacitor core, and the sandblasting gun 407 completes the sandblasting treatment of the capacitor core.

[0102] When replacing the capacitor core with a small diameter, the sandblasting gun 407 cannot continue to spray the sandblasting glass beads towards the capacitor core in the diameter direction, which will affect the sandblasting effect; at the same time, the follower sleeve 220 and the capacitor core are not in a coaxial state. At this time, the first lifting mechanism drives the turnover frame 101 to rise to ensure that capacitor cores with different diameters can also ensure that the centers of the cores are on the same center line.
