Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a flour bag stacking device for flour production, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a flour bag stacking device for flour production, comprising a mounting plate, a support block fixed to the top of the mounting plate, a placement plate fixed to the inner side of the support block, a protective device provided on the top of the mounting plate to prevent the flour bags from collapsing, an auxiliary device provided on the bottom of the placement plate to facilitate loading and unloading, and stabilizing devices provided on both sides of the placement plate to improve the stability of the flour bags; Among them, the protective device includes a support seat, a cylinder, a connecting frame, a connecting plate, a connecting rod, a protective plate, a connecting spring, a fixing block, a clamping rod and a clamping slot; the support seat is fixed on the top of the mounting plate, the cylinder is fixed on the top of the support seat, the output end of the cylinder is fixed with a connecting frame, the side of the connecting frame away from the cylinder is fixed with a connecting plate, a connecting rod passes through the connecting plate, and the penetration is slidably connected, and the protective plate is fixed to the end of the connecting rod.

[0007] According to the above technical solution, the fixing block is fixed to the top of the mounting plate, the clamping slot is opened on the side wall of the fixing block, and the clamping rod is fixed to the side wall of the protective plate.

[0008] According to the above technical solution, one side of the connecting spring is fixed to the side wall of the connecting plate, and the other side of the connecting spring is fixed to the protrusion at the end of the connecting rod.

The side wall of the blanking plate is fixed with a torsion spring, and the side of the torsion spring away from the blanking plate is fixed on the inner side of the hinge block. When the connecting plate moves, the side wall of the connecting plate does not squeeze the inclined surface of the ramp block. Through the cooperation of the transmission spring, the ramp block can be moved into the support block, so that the extrusion column does not squeeze the bottom of the blanking plate. The blanking plate can be reset by the setting of the torsion spring.

[0010] According to the above technical solution, the inclined block is slidably installed on the inner side of the support block, one side of the transmission spring is fixed on the inner side of the support block, and the other side of the transmission spring is fixed on the side wall of the inclined block.

The L-shaped plate is fixed on the outer wall of the extrusion column, and the push plate is slidably installed on the inner side of the placement plate. When the extrusion column does not squeeze the bottom of the blanking plate, the extrusion column can drive the L-shaped plate to squeeze the bottom inclined surface of the push plate, so that the compression spring is compressed when the push plate moves upward, driving the rubber block to move upward.

[0011] According to the above technical solution, one side of the compression spring is fixed to the inner side of the placement plate, the other side of the compression spring is fixed to the top of the push plate, and the rubber block is fixed to the top of the push plate.

[0012] According to the above technical solution, the stabilizing device includes an L-shaped push block, a T-shaped block, a return spring, a connecting block, a connecting seat, a cylinder, a slide plate, a connecting sleeve, a return spring, a slider, a downward block and a pressure plate; the L-shaped push block is fixed to the side wall of the inclined block, the connecting block passes through the supporting block and is slidably connected at the penetration point, the T-shaped block is fixed to the side wall of the connecting block, the connecting seat is fixed to the side wall of the connecting block away from the T-shaped block, one side of the return spring is fixed to the outer wall of the supporting block, the other side of the return spring is fixed to the side wall of the T-shaped block, and the cylinder is fixed to the inner side of the connecting seat.

When the inclined block moves, it can drive the L-shaped push block to squeeze the inclined surface of the T-shaped block, so that the T-shaped block drives the connecting block to move, and the connecting block drives the connecting seat and the cylinder to move.

[0014] The present invention provides a flour bag stacking device for flour production. It has the following beneficial effects: 1. The present invention provides a protective device. After the flour bags are stacked, the cylinder is activated to drive the connecting plate and the protective plate to move, so that the protective plate can shield and protect the flour bags stacked on the placement plate, solving the problem of flour bags stacked too high and falling. When the flour bags topple over on the placement plate, the flour bags will squeeze the protective plate to move, and the protective plate can drive the clamping rod to move, so that the clamping rod can be clamped into the clamping groove, thereby limiting the protective plate. This solves the problem that when the staff activates the cylinder to unload, if the flour bags are in an inclined state on the placement plate, when the cylinder drives the protective plate not to shield the flour bags on the placement plate, the flour bags will directly fall, posing a safety risk to the staff.

[0015] The present invention is provided with an auxiliary device. When unloading, the cylinder is started to drive the connecting plate to reset, so that the protective plate does not block the flour bag, thereby enabling the connecting plate to squeeze the inclined surface of the inclined block, thereby enabling the inclined block to drive the squeezing column to move, so that the squeezing column squeezes the unloading plate from the bottom of the placement plate to expand in an inclined shape, thereby facilitating the flour bag to slide down and unloading. After the flour bags are stacked on the placement plate, the cylinder is started to make the connecting plate block the flour bags, so that the connecting plate does not squeeze the inclined surface of the inclined block, and the transmission spring can drive the inclined block to reset through the transmission spring, thereby enabling the squeezing column to drive the L-shaped plate to squeeze the bottom inclined surface of the push plate, so that the push plate can drive the rubber block to move upward, so that the rubber block rests on the bottom of the flour bag, thereby increasing the friction between the bottom flour bag and the top of the placement plate, thereby increasing the stability of the bottom flour bag and preventing the bottom flour bag from sliding and causing the top flour bag to collapse.

[0016] 3. The present invention provides a stabilizing device. When the cylinder drives the connecting plate to not shield and protect the flour bags, the inclined surface block drives the L-shaped push block to not squeeze the T-shaped block. Through the cooperation of the return spring, the cylinder can be pressed on the flour bags. When the flour bags are unloaded or pulled out, the remaining flour bags are also driven to move, causing the remaining flour bags to collapse. When the cylinder drives the connecting plate to shield the flour bags, the inclined surface block drives the L-shaped push block to squeeze the inclined surface of the T-shaped block, so that the connecting seat can be moved closer to the support block. Through the cooperation of the slide plate, the connecting sleeve, the downward moving block, the slider and the pressing plate, the pressing plate can squeeze the top of the flour bags that are stacked too high, further improving the stability of the flour bags.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1-9 One embodiment of the present invention is: a flour bag stacking device for flour production, comprising a mounting plate 1, a support block 2 is fixed on the top of the mounting plate 1, a placement plate 5 is fixed on the inner side of the support block 2, a protective device is provided on the top of the mounting plate 1 to prevent the flour bags from collapsing, an auxiliary device is provided at the bottom of the placement plate 5 to facilitate loading and unloading, and stabilizing devices are provided on both sides of the placement plate 5 to improve the stability of the flour bags; wherein the protective device comprises a support seat 61, a cylinder 62, a connecting frame 63, a connecting plate 64, a connecting rod 65, a protective plate 66, a connecting spring 67, a fixing block 68, a clamping rod 69 and a clamping slot 610; a support The seat 61 is fixed to the top of the mounting plate 1, the cylinder 62 is fixed to the top of the support seat 61, and a connecting frame 63 is fixed to the output end of the cylinder 62. A connecting plate 64 is fixed to the side of the connecting frame 63 away from the cylinder 62. A connecting rod 65 passes through the connecting plate 64, and the penetration is slidably connected. The protective plate 66 is fixed to the end of the connecting rod 65, and the fixing block 68 is fixed to the top of the mounting plate 1. The slot 610 is opened on the side wall of the fixing block 68, and the clamping rod 69 is fixed to the side wall of the protective plate 66. One side of the connecting spring 67 is fixed to the side wall of the connecting plate 64, and the other side of the connecting spring 67 is fixed to the protrusion at the end of the connecting rod 65.

[0021] Four protective plates 66 are provided, and two protective plates 66 form a group. The two groups of protective plates 66 are symmetrically arranged with the vertical center line of the mounting plate 1 as the symmetry axis. After the flour bags are stacked, the cylinder 62 is activated to drive the connecting plate 64 and the protective plates 66 to move, so that the protective plates 66 can shield and protect the flour bags stacked on the placement plate 5, solving the problem of flour bags falling due to being stacked too high. And when the flour bag falls on the placement plate 5, the flour bag will squeeze the protective plate 66 to move, so that the protective plate 66 can drive the clamping rod 69 to move, so that the clamping rod 69 can be stuck in the clamping groove 610, thereby limiting the protective plate 66, solving the problem that when the staff starts the cylinder 62 to unload, if the flour bag is in an inclined state on the placement plate 5, when the cylinder 62 drives the protective plate 66 not to block the flour bag on the placement plate 5, the flour bag will fall directly, posing a safety risk to the staff, and the size of the clamping rod 69 matches the size of the clamping groove 610.

[0022] When this embodiment is working: when loading and unloading, when the flour bags are stacked on the placement plate 5, by starting the cylinder 62, the two groups of connecting frames 63 can be driven to approach each other, so that the two groups of connecting frames 63 drive the connecting plate 64 and the protective plate 66 to move, so that the protective plate 66 blocks the flour bags placed on the placement plate 5 to prevent the flour bags from falling. When the protective plate 66 moves to block the flour bags, the clamping rod 69 is aligned with the clamping groove 610, and when the flour bags stacked on the placement plate 5 fall, the flour bags will squeeze the protective plate 66, so that the protective plate 66 is close to the connecting plate 64, so that the connecting spring 67 is stretched, so that the clamping rod 69 extends into the slot 610, thereby fixing the connecting plate 64. When unloading, the cylinder 62 is started. Since the card rod 69 is stuck in the slot 610, the connecting plate 64 does not move the driving protective plate 66. By supporting the tilted flour bag on the placement plate 5, the flour bag does not squeeze the protective plate 66. Since the connecting spring 67 is in a stretched state, the connecting spring 67 drives the protective plate 66 to reset, and the card rod 69 is moved out of the slot 610, so that the cylinder 62 can be started, driving the two groups of connecting frames 63 away from each other, and driving the two groups of connecting plates 64 and the protective plate 66 to cover the flour bag, so that the unloading operation can be carried out.

[0023] See also Figures 1-9On the basis of the above embodiment, in another embodiment of the present invention, an auxiliary device for facilitating loading and unloading is provided at the bottom of the placing plate 5, and stabilizing devices for improving the stability of the flour bag are provided on both sides of the placing plate 5. The auxiliary devices include a hinge block 71, a blanking plate 72, a transmission spring 73, an inclined block 74, an extrusion column 75, an L-shaped plate 76, a compression spring 77, a push plate 78 and a rubber block 79; the hinge block 71 is fixed to the bottom of the placing plate 5, and the blanking plate 72 is rotatably mounted on the inner side of the hinge block 71. A torsion spring is fixed to the side wall of the blanking plate 72, and the side of the torsion spring away from the blanking plate 72 is fixed to the hinge block 71. On the inner side of the connecting block 71, the inclined block 74 is slidably installed on the inner side of the supporting block 2, one side of the transmission spring 73 is fixed on the inner side of the supporting block 2, the other side of the transmission spring 73 is fixed on the side wall of the inclined block 74, the extrusion column 75 is fixed on the side wall of the inclined block 74, the outer wall of the extrusion column 75 is fitted with the bottom of the blanking plate 72, the L-shaped plate 76 is fixed on the outer wall of the extrusion column 75, the push plate 78 is slidably installed on the inner side of the placing plate 5, one side of the compression spring 77 is fixed on the inner side of the placing plate 5, the other side of the compression spring 77 is fixed on the top of the push plate 78, and the rubber block 79 is fixed on the top of the push plate 78.

[0024] There are two groups of blanking plates 72, and the two groups of blanking plates 72 are symmetrically arranged with the center line of the mounting plate 1 in the vertical direction as the symmetry axis. When unloading, the cylinder 62 is started to drive the connecting plate 64 to reset, so that the protective plate 66 does not block the flour bag, so that the connecting plate 64 can squeeze the inclined surface of the inclined block 74, so that the inclined block 74 can drive the squeezing column 75 to move, so that the squeezing column 75 squeezes the blanking plate 72 from the bottom of the placement plate 5 to expand into an inclined shape, thereby facilitating the flour bag to slide down and facilitate unloading; When the flour bags are stacked on the placement plate 5, the cylinder 62 is activated to block the flour bags with the connecting plate 64, so that the connecting plate 64 does not squeeze the inclined surface of the inclined surface block 74. The transmission spring 73 can drive the inclined surface block 74 to reset, so that the squeezing column 75 drives the L-shaped plate 76 to squeeze the bottom inclined surface of the push plate 78, and the push plate 78 can drive the rubber block 79 to move upward, so that the rubber block 79 rests on the bottom of the flour bags, increasing the friction between the bottom flour bags and the top of the placement plate 5, thereby increasing the stability of the bottom flour bags and preventing the bottom flour bags from sliding and causing the top flour bags to collapse.

[0025] The stabilizing device includes an L-shaped push block 81, a T-shaped block 83, a return spring 86, a connecting block 82, a connecting seat 84, a cylinder 85, a slide plate 87, a connecting sleeve 88, a return spring 811, a slider 810, a downward moving block 89 and a pressure plate 812; the L-shaped push block 81 is fixed to the side wall of the inclined block 74, the connecting block 82 passes through the support block 2 and is slidably connected at the penetration point, the T-shaped block 83 is fixed to the side wall of the connecting block 82, the connecting seat 84 is fixed to the side wall of the connecting block 82 away from the T-shaped block 83, and one side of the return spring 86 is fixed to the support block 2 The outer wall of the block 83, the other side of the return spring 86 is fixed to the side wall of the T-block 83, the cylinder 85 is fixed to the inner side of the connecting seat 84, the slide plate 87 is slidably installed on the top of the connecting block 82, the connecting sleeve 88 is fixed to the top of the connecting seat 84, the slider 810 is slidably installed on the inner wall of the connecting sleeve 88, one side of the return spring 811 is fixed to the inner wall of the connecting sleeve 88, the other side of the return spring 811 is fixed to the bottom of the slider 810, the lowering block 89 is fixed to the top of the slider 810, and the pressing plate 812 is fixed to the bottom of the lowering block 89.

[0026] When the cylinder 62 drives the connecting plate 64 to stop shielding the flour bag, the inclined surface block 74 drives the L-shaped push block 81 to stop squeezing the T-shaped block 83. Through the cooperation of the return spring 86, the cylinder 85 can be squeezed on the flour bag, so that when the flour bag is unloaded, when the flour bag is pulled out for taking, the remaining flour bags are also driven to move, causing the remaining flour bags to collapse; and when the cylinder 62 drives the connecting plate 64 to block the flour bag, the inclined surface block 74 drives the L-shaped push block 81 to squeeze the inclined surface of the T-shaped block 83, so that the connecting seat 84 can be moved closer to the support block 2. Through the cooperation of the slide plate 87, the connecting sleeve 88, the downward moving block 89, the slide block 810 and the pressing plate 812, the pressing plate 812 can squeeze the top of the flour bag that is stacked too high, further improving the stability of the flour bag.

[0027] When the cylinder 62 drives the connecting frames 63 to move closer to each other, the connecting plates 64 will not squeeze the inclined surfaces of the inclined blocks 74. Because the transmission springs 73 are in a stretched state, the inclined blocks 74 can drive the squeezing posts 75 to reset, so that the squeezing posts 75 do not squeeze the bottom of the blanking plate 72. When the inclined surface block 74 moves toward the support block 2, the elastic coefficient of the transmission spring 73 is five times that of the compression spring 77, which enables the squeezing column 75 to squeeze the bottom inclined surface of the push plate 78, thereby enabling the squeezing column 75 to squeeze the push plate 78 upward and drive the rubber block 79 to move upward, so that the rubber block 79 can be squeezed on the bottom of the flour bag, and when the inclined surface block 74 moves out of the support block 2, it can drive the squeezing column 75 not to squeeze the inclined surface of the bottom of the push plate 78. Because the compression spring 77 is in a compressed state, it can drive the push plate 78 to move downward, so that the push plate 78 drives the rubber block 79 to move downward, thereby not squeezing the bottom of the flour bag, making it convenient to take it out; When the transmission spring 73 drives the inclined surface block 74 to move into the support block 2, and the elastic coefficient of the transmission spring 73 is five times the elastic coefficient of the return spring 86, when the inclined surface block 74 moves into the support block 2, it can drive the L-shaped push block 81 to squeeze the inclined surface of the T-shaped block 83, so that the T-shaped block 83 moves away from the support block 2, causing the return spring 86 to stretch, so that the two sets of connecting seats 84 move away from each other. When unloading, the connecting plate 64 will squeeze the inclined surface of the inclined surface block 74, so that the inclined surface block 74 moves out of the support block 2, causing the transmission spring 73 to stretch, so that the L-shaped push block 81 does not squeeze the inclined surface of the T-shaped block 83. Because the return spring 86 is in a stretched state, the return spring 86 can drive the connecting block 82 to move, so that the connecting seat 84 drives the cylinder 85 to fit tightly with the flour bag; When the two groups of connecting seats 84 move away from each other, the slide plate 87 can contact the support block 2, and the elastic coefficient of the return spring 86 is five times the elastic coefficient of the return spring 811. When the connecting seats 84 continue to move away from each other, the slide plate 87 will be squeezed on the support block 2, so that the slide plate 87 approaches the connecting seat 84, so that the slide plate 87 squeezes the inclined surface of the lower block 89, causing the lower block 89 to move downward, driving the slider 810 to move downward, compressing the return spring 811, and driving the pressure plate 812 to move downward, so that the pressure plate 812 is pressed against the top of the flour bag to compress the stacked flour. When unloading, the two groups of connecting seats 84 move close to each other, so that the slide plate 87 is not subject to the squeezing force, and the return spring 811 is in a compressed state, so that the slider 810 can drive the lower block 89 to move the pressure plate 812 upward without squeezing the flour bag.

[0028] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
