Description

Technical Field

[0001] This utility model relates to the field of cement production, and in particular to a cement packaging bag dispensing device. Background Technology

[0002] Cement bags are bags used to package cement and other building materials. They are usually made of wear-resistant, moisture-proof, and waterproof materials to ensure that the cement is not damaged or damp during transportation and storage. Dispensing devices are used in the transportation and production of cement bags to facilitate the transfer of cement bags to different production lines.

[0003] The following problems exist in the current process of transferring and disposing of cement packaging bags:

[0004] To maintain stability during the transfer of cement bags, they are typically laid flat. However, this method involves removing the supporting structure from the bottom of the bag as it falls. Since the bags fall at varying speeds, some sections of the bag may become bent, hindering subsequent work. Therefore, this application proposes a cement bag dispensing device. Utility Model Content

[0005] This utility model provides a cement packaging bag dispensing device, which can solve the problem in the prior art where, when transporting cement packaging bags by laying them flat, the supporting structure on the bottom of the cement packaging bag is pulled out during the process of lowering the cement packaging bag, and the different falling speeds of the cement packaging bag at different points during the falling process cause some of the cement packaging bags to bend after falling, which is not conducive to the progress of subsequent work.

[0006] A cement bag dispensing device includes a lifting unit, a feeding assembly, and a lifting device for supporting and lowering the cement bag body.

[0007] The feeding assembly is connected to the lifting unit, and the lifting device is located below the lifting unit;

[0008] The lifting unit includes a support mechanism, a moving block, and a moving component;

[0009] At least two support mechanisms are provided, with the two support mechanisms symmetrically distributed. The support mechanisms are mounted on the movable block, and the movable component is connected to the movable block.

[0010] The support mechanism includes a first support roller, a second support roller, a support plate, and a lifting frame;

[0011] Both the first support roller and the second support roller are inserted into the support plate, which is mounted on the lifting frame.

[0012] The cement packaging bag is in a transportable state. When the cement packaging bag is in a transportable state, the cement packaging bag can be divided into two inclined sections and an arc-shaped section.

[0013] In a further technical solution, the first support roller is movably connected to the support plate via a bearing.

[0014] In a further technical solution, the second support roller and the support plate are rotatably connected by a bearing, and the support plate is set at an angle.

[0015] In a further technical solution, when the cement packaging bag body is in the handling state, the two inclined sections are symmetrically distributed at the midpoint of the arc-shaped section, and the cement packaging bag body is stacked layer by layer on the upper side of the first support roller and the second support roller. The angle of inclination of the inclined section is parallel to the line connecting the midpoints of the first support roller and the second support roller.

[0016] In a further technical solution, the support mechanism is provided with a spacer and a buffer unit. There are two spacers, and the two spacers are respectively fitted onto the first support roller and the second support roller.

[0017] In a further technical solution, the buffer unit includes a buffer tube, a buffer rod, and a buffer spring. The buffer rod is inserted into the buffer tube, and the buffer rod and the buffer tube can only move relative to each other vertically.

[0018] In a further technical solution, the buffer rod is connected to the lifting frame, the buffer tube is set on the moving block, one end of the buffer spring is connected to the buffer rod, and the other end of the buffer spring is connected to the inner wall of the buffer tube.

[0019] In a further technical solution, the moving component includes a power housing, a lead screw, a drive motor, and a transmission mechanism.

The moving blocks are inserted into the power housing, and the threads of the lead screw at the two moving blocks are opposite in direction.

[0020] A further technical solution is that the lifting unit is equipped with a spinning unit, which includes an upper pressure roller, an inclined plate, and a spinning motor.

[0021] In a further technical solution, the output shaft of the spinning motor is connected to the inclined plate, and the upper pressure roller is inserted into the inclined plate. When the upper pressure roller presses on the cement packaging bag body, the upper pressure roller is located between the first support roller and the second support roller.

[0022] Beneficial effects:

[0023] This utility model provides a cement packaging bag dispensing device. In the feeding area, cement packaging bags are stacked layer by layer on the lifting unit. In the unloading area, a portion of cement packaging bags have already been placed. Two sets of first and second support rollers in the two support mechanisms support the cement packaging bags from below, so that the cement packaging bags are in a transport state. At this time, the middle of the cement packaging bag has an arc-shaped section and the two sides have inclined sections. After the two sides of the cement packaging bag are lifted and the support mechanisms fall onto the bottom of the cement packaging bag, the two support mechanisms can be moved away from the left and right sides respectively by the moving component. The arc-shaped section first contacts the bottom of the cement packaging bag. As the support mechanisms move, the inclined sections gradually fall and finally lay flat on the top of the bottom of the cement packaging bag. In this way, the cement packaging bags can be laid flat in the unloading area without any folds or bends. Attached Figure Description

[0031] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0032] like Figures 1 to 5 As shown in the figure, the present invention provides a cement packaging bag dispensing device, which includes a lifting unit 2 for supporting and lowering the cement packaging bag body 1, a feeding component 4, and a lifting device.

[0033] Specifically, the feeding component 4 is connected to the lifting unit 2, and the lifting device is located below the lifting unit 2.

[0034] The feeding component 4 can drive the lifting unit 2 to move back and forth, allowing the lifting unit 2 to move back and forth between the feeding area and the unloading area. The lifting device is used to drive the feeding component 4 to move up and down, and to drive the entire feeding component 4 and the lifting unit 2 to move up and down, so that when the cement packaging bag body 1 is unloaded, the first support roller 201 can abut against the upper side of the cement packaging bag body 1 at the bottom of the unloading area.

[0035] Specifically, the lifting unit 2 includes a support mechanism, a moving block 207, and a moving component 208;

[0036] At least two support mechanisms are provided, with the two support mechanisms symmetrically distributed. The support mechanisms are set on the movable block 207, and the movable component 208 is connected to the movable block 207. The movable component 208 is used to drive the movable block 207 and the support mechanism to move away from the middle part of the cement packaging bag body 1 or to drive the movable block 207 and the support mechanism to move towards each other, thereby placing the cement packaging bag body 1 in the designated area and supporting the next set of cement packaging bag bodies 1.

[0037] For more details, please refer to Figure 3 , Figure 4 The support mechanism includes a first support roller 201, a second support roller 202, a support plate 203, and a lifting frame 205;

[0038] It should be mentioned that both the first support roller 201 and the second support roller 202 are inserted into the support plate 203. It should also be noted that the first support roller 201 is movably connected to the support plate 203 through a bearing, and the second support roller 202 is rotatably connected to the support plate 203 through a bearing. The support plate 203 is inclined and is mounted on the lifting frame 205.

[0039] Furthermore, the cement packaging bag body 1 is in a transport state. When the cement packaging bag body 1 is in the transport state, the cement packaging bag body 1 can be divided into two inclined sections 101 and an arc-shaped section 102. The two inclined sections 101 are symmetrically distributed around the midpoint of the arc-shaped section 102. The cement packaging bag body 1 is stacked layer by layer on the upper side of the first support roller 201 and the second support roller 202. The angle of inclination of the inclined section 101 is parallel to the line connecting the midpoints of the first support roller 201 and the second support roller 202.

[0040] In the loading area, cement packaging bags 1 are stacked layer by layer onto the lifting unit 2. In the unloading area, some cement packaging bags 1 have already been placed. At this time, the lifting unit 2 needs to lay the cement packaging bags 1 flat on the bottom cement packaging bags 1. After laying them flat, the cement packaging bags 1 are in a flat state. Specifically, the two sets of first support rollers 201 and second support rollers 202 in the two sets of support mechanisms are respectively supported under the two inclined sections 101, so that the cement packaging bags 1 are in a transport state. At this time, the middle of the cement packaging bags 1 has the shape of the arc section 102, and the two sides are inclined. The inclined section 101 is shaped such that the two sides of the cement bag body 1 are raised. After the support mechanism falls onto the cement bag body 1 at the bottom, the two support mechanisms can be moved away from the left and right sides respectively by the moving component 208. The arc section 102 first contacts the cement bag body 1 at the bottom. As the support mechanism moves, the inclined section 101 gradually falls down and finally lays flat on the upper side of the cement bag body 1 at the bottom (the absence of the cement bag body 1 at the bottom does not affect the operation of the equipment). In this way, the cement bag body 1 can be laid flat in the feeding area, and the cement bag body 1 will not have any folds or bends after being laid down.

[0041] As the support mechanism moves away from the cement bag body 1, the first support roller 201 will squeeze and push the cement bag body 1 at the bottom, which can flatten the cement bag body 1 with wrinkles at the bottom, so that the cement bag body 1 is evenly distributed in the feeding area, which is convenient for subsequent use (mainly for taking out cement during packaging).

[0042] Furthermore, the support mechanism is equipped with spacers 204 and buffer units 206. Two spacers 204 are provided, one fitted onto the first support roller 201 and the other onto the second support roller 202. The buffer unit 206 includes a buffer tube 2061, a buffer rod 2062, and a buffer spring 2063. The buffer rod 2062 is inserted into the buffer tube 2061, and the buffer rod 2062 and buffer tube 2061 can only move vertically relative to each other. The buffer rod 2062 is connected to the lifting frame 205. The buffer tube 2061 is mounted on the moving block 207. One end of the buffer spring 2063 is connected to the buffer rod 2062, and the other end is connected to the inner wall of the buffer tube 2061. The buffer unit 206 serves to limit the supporting force when the first support roller 201 presses the bottom of the cement packaging bag body 1, preventing excessive pressure from causing the cement packaging bag body 1 to move.

[0043] The spacer 204 is used to restrict and isolate the cement packaging bag body 1 from the support plate 203.

[0044] It should be noted that the moving component 208 includes a power housing 2081, a lead screw 2082, a drive motor 2083, and a transmission mechanism. The output end of the drive motor 2083 is connected to the lead screw 2082 through the transmission mechanism. The transmission mechanism can be a coupling or a gear set, both of which can drive the lead screw 2082. The moving blocks 207 are inserted into the power housing 2081, and the threads of the lead screw 2082 at the two moving blocks 207 have opposite directions. In this way, the drive motor 2083 drives the lead screw 2082 to rotate, which can drive the two moving blocks 207 to move closer or further apart, thus realizing the support and lowering of the cement packaging bag body 1.

[0045] Furthermore, a spinning unit 3 is provided at the lifting unit 2. The spinning unit 3 includes an upper pressure roller 301, an inclined plate 302, and a spinning motor 303. The output shaft of the spinning motor 303 is connected to the inclined plate 302. The upper pressure roller 301 is inserted into the inclined plate 302. When the upper pressure roller 301 presses on the cement packaging bag body 1, the upper pressure roller 301 is located between the first support roller 201 and the second support roller 202. Figure 5 When the upper pressure roller 301 on the left moves to the side pressing on the cement packaging bag body 1, the trajectory of the movement is such that the upper pressure roller 301 lifts up to the side and falls onto the cement packaging bag body 1. The trajectory of the movement will not collide with the movement of the support mechanism, and the upper pressure roller 301 presses on the upper side of the cement packaging bag body 1, which can prevent it from falling off during transportation.

[0046] In summary, the cement packaging bag dispensing device provided by this utility model allows cement packaging bag bodies 1 to be stacked layer by layer on the lifting unit 2 in the feeding area. In the unloading area, a portion of cement packaging bag bodies 1 has already been placed. The two sets of first support rollers 201 and second support rollers 202 in the two sets of support mechanisms are respectively supported under the two inclined sections 101, so that the cement packaging bag bodies 1 are in a transport state. At this time, the middle of the cement packaging bag body 1 is in the shape of an arc section 102, and the two sides are in the shape of inclined sections 101. After the two sides of the cement packaging bag body 1 are lifted and the support mechanism falls on the bottom cement packaging bag body 1, the two support mechanisms can be moved away from the left and right sides respectively by the moving component 208. The arc section 102 first contacts the bottom cement packaging bag body 1. As the support mechanism moves, the inclined section 101 gradually falls down and finally lays flat on the top side of the bottom cement packaging bag body 1. In this way, the cement packaging bag body 1 can be laid flat in the unloading area, and the cement packaging bag body 1 will not have any folds or bends after being placed down.

[0047] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
