Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0030] Please refer to Figure 2 、 Figure 5 As shown, the present utility model is an automatic bag-breaking and blanking device for the raw material package of castable, including a support frame 1. A conveying device 2 is fixedly installed at the top of the support frame 1. A cross support screw 3 is threadedly connected to the inner wall of the support frame 1. A clamping assembly 4 is threadedly connected to the outer surface of the cross support screw 3. A lifting drive device 5 is fixedly installed at the top of the support frame 1. The output end of the lifting drive device 5 is fixedly connected to a connecting and rotating device 6. An elastic clamping assembly 7 is fixedly installed on the outer surface of the connecting and rotating device 6. A displacement drive device 8 is arranged on the outer surface of the support frame 1. The output end of the displacement drive device 8 is threadedly connected to a transverse displacement assembly 9. A cutting knife 10 is fixedly connected to one side surface of the transverse displacement assembly 9.

[0031] When continuous feeding of the raw material for the castable is required, by starting the conveying device 2, the raw material package is placed vertically and flat on the conveying device 2, and it is conveyed to the inside of the support frame 1 through the conveying device 2. The distance between the clamping assemblies 4 is adjusted by rotating the cross support screw 3 according to the volume of the raw material package, so that the raw material package is clamped between the clamping assemblies 4 when it falls. After the raw material package falls, the lifting drive device 5 drives the connecting and rotating device 6 to descend until the bottom of the elastic clamping assembly 7 is sprung open and clamped on both sides of the top of the raw material package and then stops. At this time, the raw material package is between the clamping assemblies 4. By starting the displacement drive device 8 at the bottom, it drives the transverse displacement assembly 9 to displace along one side of the bottom of the clamping assembly 4, thereby driving the cutting knife 10 to displace, so that the cutting knife 10 contacts the bottom of the raw material package during displacement to generate friction to break open the bottom of the raw material package. When the cutting knife 10 moves to the other end, the bottom of the raw material package is completely broken open and automatically blanked, and at the same time its top is clamped by the elastic clamping assembly 7. After the blanking is completed, the connecting and rotating device 6 drives the elastic clamping assembly 7 to rotate to drive the packaging bag to turn up upwards to cooperate with the inside of the clamping assembly 4 to complete the blanking process.

[0032] The utility model connects the cutter 10 with the transverse movement component 9, and makes the cutter 10 located below the clamping component 4, so that when the raw material bag is conveyed to the inner side of the support frame 1 by the conveying device 2 and automatically falls into the inner side of the clamping component 4, the lifting drive device 5 drives the elastic clamping component 7 to descend to clamp the top of the raw material bag, and the displacement drive device 8 drives the transverse movement component 9 to move to drive the cutter 10 to move, thereby realizing the process of automatic feeding, breaking and dropping of the raw material bag, and the connecting device 6 and the lifting drive device 5 can drive the elastic clamping component 7 to drive the packaging bag to rotate and rise, so as to process the packaging bag after the feeding is completed, so as to facilitate the subsequent continuous feeding operation and improve the efficiency of the casting material feeding operation.

[0033] In one embodiment, for the above-mentioned conveying device 2, the conveying device 2 includes a fixed frame 201, a conveying bed 202 is arranged on the top of the fixed frame 201, a conveying roller 203 is arranged on the inner wall of the conveying bed 202, and one end of the conveying bed 202 extends to the inner side of the supporting frame 1.

[0034] The conveying bed 202 is supported on one side of the support frame 1 by the fixing frame 201 so that its conveying level is higher than the top of the clamping assembly 4, thereby providing automatic conveying driving force for the casting material bag and reducing the labor intensity of manual feeding.

[0035] In one embodiment, for the above-mentioned cross bracing screws 3, there are several groups of cross bracing screws 3, and there are two clamping assemblies 4. Both clamping assemblies 4 include a threaded block 401, and one end of the threaded block 401 is fixedly connected to a clamping plate 402.

[0036] By passing the cross-bracing screw 3 through the threaded block 401, the clamping plate 402 is supported on the inner side of the support frame 1. When the cross-bracing screw 3 is rotated, the threaded block 401 can be driven to move along its outer side to drive the clamping plate 402 to move, and then the distance between the clamping plates 402 can be adjusted so that it can clamp the raw material package on its inner side to facilitate its dropping.

[0037] In one embodiment, for the above-mentioned displacement driving device 8, the displacement driving device 8 includes a displacement motor 801, the output end of the displacement motor 801 is fixedly connected to a screw 802, the transverse movement assembly 9 includes a transverse movement sleeve 901, one end of the transverse movement sleeve 901 is fixedly connected to a transverse plate 902, and the cutter 10 is fixed to the inner wall of the transverse plate 902.

[0038] The displacement motor 801 is fixed to the outside of the support frame 1. When the displacement motor 801 is started, the screw rod 802 is driven to rotate, thereby driving the transverse sleeve 901 to move, so that the transverse plate 902 and the front end cutter 10 are moved from one end of the screw rod 802 to the other end, so that the cutter 10 can contact the bottom of the raw material package.

[0039] By supporting the screw rod 802 on the inner side of the support frame 1 and close to the bottom of the clamping plate 402, the screw rod 802 can provide a lateral driving force for the transverse plate 902 and the cutter 10 through cooperation with the displacement motor 801, so that the cutter 10 can make a reciprocating motion at the bottom of the clamping plate 402, forming a driving force and generating friction on the bottom of the raw material package to realize the package breaking operation, so that the raw material package can be automatically broken and dropped, thereby improving the feeding efficiency.

[0040] In one embodiment, for the above-mentioned lifting drive device 5, the lifting drive device 5 includes a lifting cylinder 501, the output end of the lifting cylinder 501 is fixedly connected to a telescopic shaft 502, one end of the telescopic shaft 502 is fixedly connected to a lifting block 503, and the lifting block 503 is slidably connected to the inner wall of the support frame 1.

[0041] The lifting cylinder 501 is fixed to the top of the support frame 1. The lifting cylinder 501 drives the telescopic shaft 502 to extend and retract, thereby pushing the lifting block 503 to move up and down on the inner side of the support frame 1, thereby driving the connecting device 6 and the elastic clamping component 7 to move on the inner side of the support frame 1 until the bottom of the elastic clamping component 7 is squeezed and bounced open by the top of the raw material package, so that the elastic clamping component 7 is clamped on the outside of the raw material package and stops. When the raw material package is dropped, the telescopic shaft 502 drives it to move in the opposite direction and rise.

[0042] In one embodiment, for the above-mentioned continuous rotation device 6, the continuous rotation device 6 includes a continuous rotation motor 601, and the output end of the continuous rotation motor 601 is fixedly connected to a rotating rod 602, and one end of the rotating rod 602 extends to the inside of the lifting block 503 and is rotatably connected thereto.

[0043] When the continuously rotating motor 601 is driven to rise and reset, the top of the casting material packaging bag is clamped on the inner side of the elastic clamping component 7, and the rotating rod 602 is driven by the continuously rotating motor 601 to drive the elastic clamping component 7 to flip upward, so that the packaging bag can be lifted upward to separate from the inner side of the clamping plate 402, thereby achieving the effect of clearing the packaging bag.

[0044] In one embodiment, for the above-mentioned elastic clamping assembly 7, there are two groups of the elastic clamping assembly 7, and the elastic clamping assembly 7 includes a top clamping plate 701, and the interior of the top clamping plate 701 is fixedly connected with a connecting rod 702, and the outer surface of the connecting rod 702 is provided with a bidirectional spring 703, and one end of the bidirectional spring 703 is fixedly connected with a bidirectional clamping plate 704.

[0045] The top clamping plate 701 is sleeved on the outside of the rotating rod 602. When the top clamping plate 701 is driven by the telescopic shaft 502 to move downward, the two-way clamping plate 704 is moved downward until the two-way clamping plate 704 drops and is pushed by the top of the raw material package, causing the two-way spring 703 to move to both sides, so that the two-way clamping plate 704 is bounced open and clamped on the outside of the raw material package. When the raw material package is dropped and its volume is reduced, the two-way spring 703 gradually resets, causing the two-way clamping plate 704 to tighten inward to clamp the top of the raw material package.

[0046] By connecting the top clamping plate 701 with the rotating rod 602, the two-way spring 703 and the two-way clamping plate 704 can provide a clamping effect for the raw material package, and the continuous rotating motor 601 and the rotating rod 602 can drive it to flip upward to disengage from the inside of the clamping plate 402, thereby achieving the transfer effect of the raw material package, and subsequently continuing the blanking and feeding operations.

[0047] In one embodiment, for the above-mentioned support frame 1 , a guide slide 11 is fixedly connected to the inner wall of the support frame 1 , and a guide slide groove 12 is provided inside the guide slide 11 .

[0048] The guide slide plate 11 is located at the top of the support frame 1 , and cooperates with the guide slide groove 12 to provide sliding displacement space and limit function for the lifting block 503 and the continuous rotation motor 601 .

The displacement drive device 8 drives the transverse movement component 9 to displace, driving the cutting knife 10 to move, realizing the process of automatically feeding, breaking the package, and discharging the raw material package. In cooperation with the continuous rotation device 6 and the lifting drive device 5, the elastic clamping component 7 can be driven to drive the packaging bag to rotate and rise, so as to process the packaging bag after feeding, facilitating subsequent continuous feeding operations and improving the feeding efficiency of the castable; 2. By supporting the screw rod 802 inside the support frame 1 and near the bottom of the clamping plate 402, the transverse movement driving force can be provided for the cross plate 902 and the cutting knife 10 in cooperation with the displacement motor 801, enabling the cutting knife 10 to move back and forth at the bottom of the clamping plate 402, generating a driving force and friction on the bottom of the raw material package to achieve the bag breaking operation, enabling the raw material package to automatically break the bag and discharge, and improving the feeding efficiency; By connecting the top clamping plate 701 to the rotating rod 602, while the bidirectional spring 703 and the bidirectional clamping plate 704 can provide a clamping effect on the raw material package, the continuous rotation motor 601 and the rotating rod 602 can drive it to flip upward to disengage from the inside of the clamping plate 402, realizing the transfer effect of the raw material package for subsequent continuous discharging and feeding operations.
