Description

Technical Field

[0001] The present application relates to the technical field of turnover mechanisms, and in particular to an automatic turnover mechanism for shot blasting of sheet products. Background Art

[0002] Shot blasting machine refers to casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of castings. The shot blasting machine can simultaneously remove sand, core and clean castings. Shot blasting machines are divided into drum type, chain plate type, rotary table type, trolley type, squirrel cage type and hanging type shot blasting machines according to the structure of the casting carrier.

[0003] When the chain plate shot blasting machine is performing shot blasting on sheet products such as spring sheets, since the sheet products such as spring sheets are relatively thin, only one side of the sheet products such as spring sheets can be made close to the chain plate, and the other side is subjected to sand falling and cleaning operations by the projectiles. In this process, only one side of the sheet products such as spring sheets is subjected to sand falling and cleaning operations, and the other side is completely not exposed to the shot blasting, which greatly affects the quality of sand falling and cleaning of sheet products such as spring sheets. Summary of the invention

[0004] The present application proposes an automatic turning mechanism for shot blasting of sheet products, which has the advantages of turning over the sheet products so that both sides of the sheet products can be shot blasted, and is used to solve the problem that only one side of the sheet products is shot blasted, sanded and cleaned.

[0008] Furthermore, a stop block is fixedly installed at the connection between the mounting plate and the feed plate and the discharge plate, and the stop block is on the same plane as the mounting plate.

[0009] Furthermore, the turnover frame is provided with: two sliding grooves and a buffer groove, which are opened on one side of the closing plate close to the discharge plate, and the two sliding grooves are on both sides of the buffer groove; sliders, which are slidably installed in the sliding grooves and one end extends out of the sliding grooves; limiting grooves, which are symmetrically opened on the inner wall of the support plate between the same feed plate and the discharge plate; support shafts, the two ends of which are respectively slidably installed in the limiting grooves on both sides and the two ends penetrate through the sliders; mounting grooves, which are opened on one side of the discharge plate close to the closing plate; baffles, which are movably sleeved on the support shafts and one end extends into and protrudes out of the mounting grooves; torsion springs, the two ends of which are respectively fixedly connected to the baffles and the sliders and are movably sleeved on the support shafts, and the torsion springs are used to provide power for the reset of the baffles.

[0010] Furthermore, the end of the slider extending out of the sliding groove is arc-shaped.

[0011] Furthermore, the width of the mounting groove is the same as the width of the buffer groove.

[0012] Furthermore, the turnover frame is also provided with: a connecting rod, the two ends of which are respectively fixedly connected to the two ends of the support shaft; a plurality of power rods, which are fixedly connected to both sides of the side wall of the connecting rod; two push plates, which are respectively fixedly connected to the other ends of the power rods on both sides of the connecting rod; a T-shaped bladder, one side of which is fixedly connected to the other side of the push plate and the other side is fixedly installed on the side wall of the mounting plate of the turnover frame. The middle position of the T-shaped bladder is a telescopic bladder, and a tension spring is fixedly arranged in the telescopic bladder. The telescopic direction of the telescopic bladder is parallel to the power rod. The T-shaped bladder (1115) is filled with transmission fluid, and a plurality of support springs are fixedly installed in the T-shaped bladder.

[0013] Furthermore, the elastic push rod has a certain elasticity and can generate deformation.

[0014] The present application has the following beneficial effects:

[0015] 1. An automatic turning mechanism for shot blasting of sheet products provided by the present application. A turning support frame is provided inside the turning mechanism box. A power motor, a speed reducer, and a bearing seat are provided at the top of the turning support frame. A transmission shaft is sleeved inside the bearing seat. The power motor drives the transmission shaft to rotate through a transmission gear and a mating gear. One end of the transmission shaft is fixedly sleeved with a turning frame, and the turning frame is located on one side of the turning support frame. The turning frame is closely attached to two chain plates of the shot blasting machine main body. When the shot blasting machine main body processes the sheet products, one side of the chain plate conveys the sheet products into the shot blasting machine main body. When reaching the end point, the sheet products slide onto the feeding plate of the turning frame. Due to the rotation of the turning frame driven by the power motor after transmission, the rotating turning frame drives the sheet products to move, causing the sheet products to turn to the discharging plate of the turning frame. When the discharging plate aligns with another chain plate of the shot blasting machine main body, the sheet products on the discharging plate slide onto the other chain plate, thus completing the turning of the sheet products. The other chain plate conveys the sheet products back into the shot blasting machine main body to perform shot blasting treatment on the other side of the sheet products, so that both sides of the sheet products can be processed, avoiding affecting the quality of sand falling and cleaning of the sheet products.

[0016] 2. An automatic turning mechanism for shot blasting of sheet products provided by the present application. A buffer groove is opened on one side of the closing plate closely attached to the discharging plate. Sliding grooves are opened on both sides of the buffer groove. Sliders are slidably arranged inside the sliding grooves, and the sliders extend out of the sliding grooves. A limiting groove is opened on the inner wall of the support plate between the feeding plate and the discharging plate on the same side of the turning frame. Two ends of a support shaft are respectively slidably installed in the two limiting grooves. Two ends of the support shaft penetrate through the sliders. An installation groove is opened on one side of the closing plate closely attached to the discharging plate. A baffle is movably sleeved on the support shaft. One end of the baffle passes through the installation groove and extends out. A torsion spring is arranged between the baffle and the slider, and the torsion spring is movably sleeved on the support shaft. The torsion spring makes one side of the baffle closely attached to the side wall of the installation groove. During operation, the sheet products on one side of the chain plate of the shot blasting machine main body slide onto the feeding plate of the turning frame. After the power motor drives the turning frame to rotate through transmission, the rotating turning frame drives the sheet products to move, causing the sheet products to turn to the discharging plate of the turning frame. Since the discharging plate is an inclined plane, the protruding baffle blocks the sheet products from sliding down, preventing the sheet products on the discharging plate from sliding when they do not reach the position. And, when the discharging plate turns to face another chain plate of the shot blasting machine main body, the other chain plate squeezes the slider, causing the slider to slide into the sliding groove, thereby causing the slider to push the support shaft and the baffle to slide along the limiting groove. At this time, since the baffle is blocked by the side wall of the installation groove, the baffle rotates towards the buffer groove, and the baffle no longer blocks the sheet products on the discharging plate, enabling the sheet products to slide down.

[0017] 3. An automatic turning mechanism for shot blasting of sheet products provided by this application. Connecting rods are connected to both ends of the support shaft. A number of power rods are fixedly connected to both sides of the connecting rods. The other ends of the power rods on both sides are respectively fixedly connected with push plates. The side wall of the push plate is fixedly connected to the T-shaped bladder. The T-shaped bladder is filled with transmission fluid. The other side of the T-shaped bladder is fixedly installed on the inner wall of the turning frame. A moving block is fixedly connected to the telescopic bladder in the middle of the T-shaped bladder. The moving block extends out of the moving groove of the discharge plate. And an elastic push rod parallel to the discharge plate is fixedly connected to the moving block. When the discharge plate rotates to face another chain plate of the shot blasting machine main body, the other chain plate squeezes the slider, causing the slider to slide into the chute, so that the slider pushes the support shaft and the baffle to slide along the limit groove. At the same time, the connecting rod, the power rod and the push plate move in the same direction. The push plate squeezes the T-shaped bladder, causing the transmission fluid in the T-shaped bladder to enter the telescopic bladder of the T-shaped bladder, so that the telescopic bladder drives the moving block and the elastic push rod to move towards the baffle, thereby pushing the sheet products on the discharge plate to slide down, avoiding the friction between the sheet products and the discharge plate from hindering the sliding of the sheet products.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0028] Embodiment 1

[0029] Please refer to Figures 1 - 3 , an automatic turnover mechanism for shot blasting of sheet products, including a shot blasting machine main body 1. There are two parallel chain plates 2 arranged inside the shot blasting machine main body 1, and the conveying directions of the two chain plates 2 are opposite. A body of the turnover mechanism 3 is fixedly installed at the tail end of the shot blasting machine main body 1. A turnover support frame 4 is fixedly installed at the bottom end inside the body of the turnover mechanism 3. A power motor 5, a reducer 6 and a bearing seat 8 are fixedly installed at the top end of the turnover support frame 4. The power motor 5 and the reducer 6 are in transmission connection and are on one side of the turnover support frame 4. The bearing seat 8 is at the middle position on the side of the turnover support frame 4 close to the chain plate 2. A transmission shaft 9 is movably sleeved inside the bearing seat 8, and both ends of the transmission shaft 9 extend out of the bearing seat 8. A transmission gear 7 is fixedly sleeved on the transmission shaft of the reducer 6. A matching gear 10 is fixedly sleeved at one end of the transmission shaft 9 close to the reducer 6. The matching gear 10 meshes with the transmission gear 7. A turnover frame 11 is fixedly sleeved on the transmission shaft 9 at the other end of the bearing seat 8, and the turnover frame 11 is close to the two chain plates 2 of the shot blasting machine main body 1. The turnover frame 11 is used for flipping the sheet products.

[0030] Please refer to Figures 2 - 4, the turnover frame 11 includes a mounting plate, a feeding plate 1101, a discharging plate 1102, a supporting plate 1103 and a closing plate 1104. The mounting plate is fixedly sleeved on the transmission shaft 9. On each side of the mounting plate, a supporting plate 1103, a feeding plate 1101 and a discharging plate 1102 are sequentially connected. And the adjacent supporting plate 1103 and discharging plate 1102 on the mounting plate are fixedly connected. The other ends of the supporting plate 1103, the feeding plate 1101 and the discharging plate 1102 are fixedly connected with a closing plate 1104, and the closing plate 1104 is parallel to the mounting plate. The closing plate 1104 is used to enclose the space formed by the supporting plate 1103, the feeding plate 1101 and the discharging plate 1102. The closing plate 1104 closely adheres to the two chain plates 2 of the shot blasting machine main body 1. Another supporting plate 1103 for support is fixedly installed at the middle position between the feeding plate 1101 and the discharging plate 1102. The two supporting plates 1103 on the same feeding plate 1101 and discharging plate 1102 are arranged in parallel.

[0031] The feeding plate 1101 and the discharging plate 1102 are inclined planes, which ensure that the sheet products on the chain plate 2 can slide onto the feeding plate 1101, and the sheet products on the discharging plate 1102 can slide onto another chain plate 2.

[0032] A stop block is fixedly installed at the connection position of the mounting plate between the feeding plate 1101 and the discharging plate 1102. The stop block is on the same plane as the mounting plate. The stop block is used to block the sheet products sliding down from the feeding plate 1101 to prevent the sheet products from slipping.

[0033] The working principle of the first embodiment of the present invention is as follows:

[0034] Please refer to Figures 1 - 4 , when using the shot blasting machine to perform sand falling and cleaning operations on sheet products, the sheet products enter the shot blasting machine main body 1 through the chain plate 2 on one side, and the sand falling and cleaning operations are performed on one side of the sheet products. After reaching the end of the chain plate 2, the sheet products on the chain plate 2 slide onto the feeding plate 1101 of the turnover frame 11 along the inclined plane of the feeding plate 1101. At the same time, the power motor 5 drives through the reducer 6, the transmission gear 7 and the mating gear 10, so that the mating gear 10 drives the transmission shaft 9 and the turnover frame 11 to rotate. The sheet products on the feeding plate 1101 rotate with the feeding plate 1101. During the rotation process, the sheet products on the feeding plate 1101 are turned over to the discharging plate 1102 by the feeding plate 1101, so that the sheet products are turned over. At this time, the sheet products on the discharging plate 1102 slide along the inclined plane of the discharging plate 1102, so that the sheet products on the discharging plate 1102 slide onto the chain plate 2 on the other side. The chain plate 2 on the other side drives the sheet products back into the shot blasting machine main body 1, and the sand falling and cleaning operations are performed on the other side of the sheet products, so that both sides of the sheet products can be processed, avoiding affecting the quality of sand falling and cleaning of the sheet products.

[0035] Embodiment Two

[0036] Example 2 is a further improvement based on Example 1.

[0037] Different from Example 1, please refer to Figures 4 - 6 , two sliding grooves 1105 and a buffer groove 1106 are formed on one side of the closing plate 1104 close to the discharging plate 1102, and the two sliding grooves 1105 are located on both sides of the buffer groove 1106. Sliders 1107 are slidably installed in the sliding grooves 1105, and one end of each slider 1107 extends out of the sliding groove 1105. Limiting grooves 1108 are symmetrically formed on the inner wall of the support plate 1103 between the same feeding plate 1101 and discharging plate 1102. The limiting grooves 1108 are close to the sliding grooves 1105 on the closing plate 1104. Two ends of a support shaft 1109 are respectively slidably installed in the limiting grooves 1108 on both sides. Two ends of the support shaft 1109 penetrate through the sliders 1107. The support shaft 1109 can only slide along the limiting grooves 1108 and cannot rotate. An installation groove is formed on one side of the discharging plate 1102 close to the closing plate 1104. A baffle 1110 is movably sleeved on the support shaft 1109, and one end of the baffle 1110 extends into and protrudes from the installation groove. A torsion spring 1111 is arranged between the baffle 1110 and the slider 1107. Two ends of the torsion spring 1111 are respectively fixedly connected to the baffle 1110 and the slider 1107. The torsion spring 1111 is movably sleeved on the support shaft 1109. The torsion spring 1111 is used to provide power for the baffle 1110 to block the sheet products on the discharging plate 1102.

[0038] One end of the slider 1107 extending out of the sliding groove 1105 is arc-shaped, preventing the slider 1107 from having sharp corners, so that when the slider 1107 acts on the chain plate 2, the surface of the chain plate 2 will not be damaged.

[0039] The width of the installation groove is the same as that of the buffer groove 1106, ensuring that the baffle 1110 can rotate from the installation groove into the buffer groove 1106, and the baffle 1110 can block the buffer groove 1106 to prevent impurities from entering.

[0040] Please refer to Figures 4 - 6, both ends of the support shaft 1109 are fixedly connected to both ends of the connecting rod 1112 respectively. A number of power rods 1113 are fixedly connected to both sides of the side wall of the connecting rod 1112. The power rods 1113 are parallel to the discharge plate 1102 and perpendicular to the support shaft 1109. The other ends of the power rods 1113 on both sides of the connecting rod 1112 are fixedly connected to one side of the push plate 1114 respectively. The other side of the push plate 1114 is fixedly connected to the same T-shaped bladder 1115. The T-shaped bladder 1115 is fixedly installed on the side wall of the mounting plate of the turnover frame 11. The middle position of the T-shaped bladder 1115 is a telescopic bladder. A tension spring is fixedly arranged in the telescopic bladder. The telescopic direction of the telescopic bladder is parallel to the power rod 1113. The T-shaped bladder 1115 is filled with transmission fluid. The T-shaped bladder 1115 will not expand. A number of support springs are fixedly installed in the T-shaped bladder 1115. The axis of the support spring is parallel to the power rod 1113. A moving block 1116 is fixedly connected to the front end of the telescopic bladder of the T-shaped bladder 1115. A moving groove 1117 is formed in the discharge plate 1102. The moving block 1116 extends out of the moving groove 1117. An elastic push rod 1118 is fixedly connected to the moving block 1116 passing through the moving groove 1117. The elastic push rod 1118 is closely attached to the outer wall of the discharge plate 1102 and parallel to the baffle 1110.

[0041] The elastic push rod 1118 has a certain elasticity and can generate deformation. When the elastic push rod 1118 pushes the sheet product on the discharge plate 1102, one end of the elastic push rod 1118 will be squeezed against the feed plate 1101. At this time, the elastic push rod 1118 can generate deformation, enabling the elastic push rod 1118 to continue to push the sheet product.

[0042] The width of the T-shaped bladder 1115 is greater than the width of the moving groove 1117. This prevents the T-shaped bladder 1115 from extending out of the moving groove 1117.

[0043] The working principle of the second embodiment of the present invention is as follows:

[0044] Please refer to Figures 1 - 6, when using a shot blasting machine to perform sand falling and cleaning operations on sheet products, the sheet products enter the main body 1 of the shot blasting machine through the chain plate 2 on one side, and sand falling and cleaning operations are performed on one side of the sheet products. After reaching the end of the chain plate 2, the sheet products on the chain plate 2 slide along the inclined surface of the feed plate 1101 to the feed plate 1101 of the turnover frame 11. At the same time, the power motor 5 drives through the reducer 6, the transmission gear 7 and the mating gear 10, so that the mating gear 10 drives the transmission shaft 9 and the turnover frame 11 to rotate. The sheet products on the feed plate 1101 rotate with the feed plate 1101. During the rotation process, the sheet products on the feed plate 1101 are turned over to the discharge plate 1102 by the feed plate 1101, so that the sheet products are turned over. At this time, the sheet products on the discharge plate 1102 slide along the inclined surface of the discharge plate 1102 until the sheet products on the discharge plate 1102 slide to the protruding baffle 1110, so that the baffle 1110 blocks the sheet products and prevents the sheet products on the discharge plate 1102 from sliding off when the discharge plate 1102 does not rotate to the chain plate 2 on the other side, resulting in the problem of offset of the position where the sheet products are prevented;

[0045] Moreover, when the discharge plate 1102 rotates to face another chain plate 2 of the shot blasting machine main body 1, the other chain plate 2 squeezes the slider 1107 on the turnover frame 11, so that the slider 1107 slides into the chute 1105, thereby causing the slider 1107 to push the support shaft 1109 and the baffle 1110 to slide along the limit groove 1108. At this time, since the baffle 1110 is blocked by the side wall of the installation groove, the baffle 1110 rotates towards the buffer groove 1106, and the baffle 1110 no longer blocks the sheet products on the discharge plate 1102, so that the sheet products can slide onto another chain plate 2.

[0046] Please refer to Figures 1 - 6 , when the discharge plate 1102 rotates to face another chain plate 2 of the shot blasting machine main body 1, the other chain plate 2 squeezes the slider 1107, so that the slider 1107 slides into the chute 1105, thereby causing the slider 1107 to push the support shaft 1109 and the baffle 1110 to slide along the limit groove 1108. At the same time, the support shaft 1109 pushes the connecting rod 1112, the power rod 1113 and the push plate 1114 to move in the same direction. The push plate 1114 squeezes the T-shaped bladders 1115 on both sides, so that the transmission fluid in the T-shaped bladders 1115 on both sides enters the telescopic bladder of the T-shaped bladder 1115, and the telescopic bladder elongates, so that the telescopic bladder drives the moving block 1116 and the elastic push rod 1118 to move along the moving groove 1117 towards the baffle 1110, thereby pushing the sheet products on the discharge plate 1102 to slide off and avoiding the friction between the sheet products and the discharge plate 1102 from hindering the sliding of the sheet products.
