Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a tilting and unloading device for a material cylinder. Background Technology

[0002] In the high-viscosity liquid raw material industry, such as paint production, 220L cylindrical containers are commonly used for raw material packaging and storage. In subsequent production stages, these containers need to be tilted to pour the raw material into a transfer cylinder. Since these containers are typically 200L, their weight is enormous when full. Manually moving the container and tilting it to pour the material into the transfer cylinder is extremely laborious and poses safety hazards, making it difficult to meet actual production needs. Therefore, a tilting cart is currently used to tilt the container. However, in actual use, after the tilting cart raises and tilts the container, due to the high viscosity of the raw material, residual material easily adheres to the inner wall of the container. This requires manual scraping with a shovel. When manually scraping the material, the force applied by the shovel causes the tilting cart to sway or move backward, making it difficult to stabilize. In this case, an additional person is needed to assist, supporting the cart from behind to prevent swaying or movement. This requires two workers for this workstation, resulting in wasted labor. While using automated robotic arms to replace the tipping cart can achieve the function of tipping and unloading materials, the purchase cost of a single robotic arm is usually over 200,000 RMB, which is too high for most companies in terms of initial equipment investment and poor economic efficiency. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a material cylinder tilting and unloading device that requires only one person to operate the entire process, is stable and does not require additional assistance, and has a low investment cost compared to a robotic arm.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A material cylinder tilting and unloading device includes a frame, a material cylinder lifting mechanism, and a tilting mechanism; it also includes a base, the base comprising a base, a turntable bearing, a turntable, and a turntable fixedly connected to the turntable. The base is fixed to the ground and connected to the turntable via the turntable bearing. The diameter of the turntable is larger than the diameter of the turntable. The base is provided with blind holes for the material cylinder loading position and the tilting position, respectively. The turntable is provided with a locking through hole, through which a locking pin passes and can be inserted into either the blind hole for the material cylinder loading position or the blind hole for the tilting position. The frame is fixedly mounted on the turntable. The material cylinder lifting mechanism is mounted on the frame and is used to drive the tilting mechanism to rise or fall. The tilting mechanism is used to connect to the material cylinder and drive the material cylinder to tilt.

[0006] Compared to the currently used drum tipping machines, this new design adds a base. A forklift transports the drum to the loading position, aligns the locking perforation with the blind hole at the loading position, and inserts the locking pin through the locking perforation into the blind hole. The drum tipping mechanism then secures the drum, and the drum lifting mechanism raises it. The pull cylinder moves to the tipping position. Since the base includes a base, turntable bearing, turntable, and turntable, the operator removes the locking pin and manually rotates the frame, causing the drum to rotate to the tipping position. At this point, the locking perforation aligns with the blind hole at the tipping position, and the locking pin, after passing through the locking perforation, inserts into the blind hole. The tipping mechanism then flips the drum, pouring the material into the pull cylinder. Any material adhering to the inner wall of the drum is scraped off by the operator using a shovel. Because the base is fixed to the ground, the swaying or backward movement problems present in current drum tipping machines are avoided when the shovel applies force. Furthermore, it can be operated by a single person, eliminating the need for two people and saving manpower. The diameter of the turntable is larger than that of the turntable so that the locking pin can pass through the locking hole and cooperate with the blind hole of the loading position and the blind hole of the tilting position.

[0007] In specific settings, the blind hole at the loading position and the blind hole at the tipping position are set 90° apart.

[0009] Preferably, the two sides of the support frame are fixed with support ribs between the support base and the support frame.

[0010] Preferably, the material cylinder lifting mechanism includes a hydraulic cylinder, a lifting rod, two sprockets, two chains, and a lifting plate. The hydraulic cylinder is disposed between two supports of the machine frame, and the cylinder body of the hydraulic cylinder is fixedly mounted on the support. The piston rod of the hydraulic cylinder is upwardly positioned and fixedly mounted with the lifting rod. The axis of the lifting rod is horizontally positioned. The two sprockets are rotatably mounted at both ends of the lifting rod. The two chains pass over the two sprockets respectively. One end of the chain is fixedly mounted on the turntable, and the other end of the chain is fixedly mounted on the lifting plate. The cylinder tilting mechanism is connected to the lifting plate.

[0011] Preferably, both ends of the lifting plate are fixedly installed with sliding plates, and each sliding plate is rotatably installed with two rollers. The support frame is provided with wheel grooves facing each other, and the rollers are located in the wheel grooves. The rollers and the side wall of the wheel grooves near the tipping mechanism roll in cooperation.

[0012] Preferably, the tipping mechanism includes two support arms fixedly connected to the lifting plate. The ends of the two support arms are respectively fixedly installed with a support and a motor base. A rotating shaft is rotatably installed on the support. A reduction motor is fixedly installed on the motor base. Connecting blocks are fixed to the output shaft of the rotating shaft and the reduction motor. The two connecting blocks are respectively fixedly connected to the two ends of the fixing hoop. Hoop straps are hinged to both ends of the fixing hoop. Locking buckles and locking hooks are respectively installed at the ends of the two hoop straps that are not connected to the fixing hoop. The locking buckles and locking hooks engage to connect the two hoop straps.

[0013] Preferably, the material loading position of the material cylinder is provided with a loading platform, the upper surface of the loading platform is flush with the upper surface of the turntable, and a material cylinder positioning arc plate is fixedly installed on the turntable.

[0014] Preferably, the fixing hoop is fixedly mounted with a column, the upper end of the column is fixedly mounted with an end head, the end head is hinged to a hook, one end of the hook is used to hook with the material cylinder, the other end of the hook is threaded to a screw rod, the inner end of the screw rod is positioned opposite to the column and abuts against the column, and the outer end of the screw rod is fixed with a handle.

[0015] Preferably, the tilting cylinder position is provided with a cylinder positioning structure, which includes two symmetrically arranged side positioning plates and an end positioning plate.

Both the side positioning plates and the end positioning plates are fixed to the ground by connecting columns.

[0016] In summary, this material cylinder tilting and unloading device has the advantages of requiring only one person to operate the entire process, stable operation without the need for additional assistance, and low investment cost compared to a robotic arm. Attached Figure Description

The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0025] like Figure 1-7 As shown, a material cylinder tilting and unloading device includes a frame, a material cylinder lifting mechanism, and a tilting mechanism; it also includes a base, which includes a base 11, a turntable bearing 12, a turntable 13, and a turntable 14 fixedly connected to the turntable. The base is fixed to the ground and connected to the turntable through the turntable bearing. The diameter of the turntable is larger than that of the turntable. The base is provided with blind holes 15 for the material cylinder loading position and blind holes 16 for the tilting position, respectively. The turntable is provided with a locking through hole 17, through which a locking pin 18 passes and can be inserted into the blind hole for the material cylinder loading position or the blind hole for the tilting position. The frame is fixedly mounted on the turntable. The material cylinder lifting mechanism is mounted on the frame and is used to drive the tilting mechanism to rise or fall. The tilting mechanism is used to connect with the material cylinder 19 and drive the material cylinder to tilt.

[0026] Compared to the currently used drum tipping machines, this new design adds a base. A forklift transports the drum to the loading position, aligns the locking perforation with the blind hole at the loading position, and inserts the locking pin through the locking perforation into the blind hole. The drum tipping mechanism then secures the drum, and the drum lifting mechanism raises it. The pull cylinder moves to the tipping position. Since the base includes a base, turntable bearing, turntable, and turntable, the operator removes the locking pin and manually rotates the frame, causing the drum to rotate to the tipping position. At this point, the locking perforation aligns with the blind hole at the tipping position, and the locking pin, after passing through the locking perforation, inserts into the blind hole. The tipping mechanism then flips the drum, pouring the material into the pull cylinder. Any material adhering to the inner wall of the drum is scraped off by the operator using a shovel. Because the base is fixed to the ground, the swaying or backward movement problems present in current drum tipping machines are avoided when the shovel applies force. Furthermore, it can be operated by a single person, eliminating the need for two people and saving manpower. The diameter of the turntable is larger than that of the turntable so that the locking pin can pass through the locking hole and cooperate with the blind hole of the loading position and the blind hole of the tilting position.

[0027] In specific settings, the blind holes at the loading position and the blind holes at the tipping position are set at 90° intervals.

[0028] In specific implementation, the frame includes a support 2 fixedly installed on the turntable, and vertically arranged support frames 21 are fixedly installed on both sides of the support 21. The upper ends of the two support frames are fixedly connected by a cross arm 22.

[0029] In this way, the frame consists of a support base, a support frame, and a cross arm. The support base is fixed on the turntable and serves as a basic support. The vertical support frames on both sides provide a stable installation position for the material cylinder lifting mechanism and the cylinder tilting mechanism. The cross arm at the top connects the two support frames, which enhances the overall structural strength and stability of the frame and ensures that the frame will not deform or shake due to force during the lifting and tilting of the material cylinder, thereby ensuring the reliability of the entire device operation.

[0030] In practice, support ribs 23 are fixed between the two sides of the support frame and the support base.

[0031] This design further enhances the structural stability of the frame. When the lifting mechanism raises the heavier cylinder and the tilting mechanism flips the cylinder, significant forces are generated. The support ribs effectively disperse these forces, preventing damage to the connection between the support frame and the support base due to excessive stress. This extends the service life of the device and also improves safety during operation.

[0032] In specific implementation, the material cylinder lifting mechanism includes a hydraulic cylinder 24, a lifting rod 25, two sprockets 26, two chains 27, and a lifting plate 28. The hydraulic cylinder is located between two supports of the machine frame, and the cylinder body of the hydraulic cylinder is fixedly installed on the support. The piston rod of the hydraulic cylinder is set upward and fixedly installed with the lifting rod. The axis of the lifting rod is set horizontally. The two sprockets are respectively rotatably installed at both ends of the lifting rod. The two chains pass around the two sprockets respectively. One end of the chain is fixedly installed on the turntable, and the other end of the chain is fixedly installed on the lifting plate. The cylinder tilting mechanism is connected to the lifting plate.

[0033] In this way, the hydraulic cylinder is fixed on the support, and the piston rod pushes the lifting rod upward. The sprockets at both ends of the lifting rod drive the chain, thereby raising and lowering the lifting plate, which in turn drives the connected tilting mechanism and the material cylinder to rise or fall. Utilizing the stability of hydraulic transmission and the reliability of sprocket and chain transmission, heavier material cylinders can be lifted smoothly. Compared with other lifting methods, the lifting speed and height can be precisely controlled to meet the material unloading needs under different working conditions.

[0034] In specific implementation, slide plates 29 are fixedly installed at both ends of the lifting plate, and two rollers 3 are rotatably installed on each slide plate. The support frame has wheel grooves 31 facing each other, and the rollers are located in the wheel grooves. The rollers and the side wall of the wheel grooves near the tipping mechanism roll in cooperation.

[0035] In this way, during the lifting process, the rollers roll in the groove and cooperate with the side wall near the tilting mechanism to guide the lifting of the lifting plate, ensuring the smoothness of the lifting process, avoiding the lifting plate from deviating or getting stuck, and also effectively reducing the friction during the lifting process, reducing energy consumption, reducing equipment wear, and improving the operating efficiency and service life of the device.

[0036] Specifically, the material cylinder has a certain weight, and the material cylinder lifting mechanism applies the lifting force to the lifting plate through the chain. The lifting plate and the material cylinder are eccentrically set, so the rollers can fit tightly in the wheel groove, ensuring stable and smooth lifting and avoiding friction.

[0037] In specific implementation, the tilting mechanism includes two support arms 32 fixedly connected to the lifting plate. The ends of the two support arms are respectively fixedly installed with a support 33 and a motor base 34. The support is rotatably mounted with a rotating shaft. The motor base is fixedly mounted with a reduction motor 35. The output shaft of the rotating shaft and the reduction motor are both fixed with connecting blocks 36. The two connecting blocks are respectively fixedly connected to both ends of a fixing hoop 37. Both ends of the fixing hoop are hinged with hoop straps 38. The ends of the two hoop straps that are not connected to the fixing hoop are respectively installed with a buckle 39 and a hook 4. The buckle and the hook engage to connect the two hoop straps.

[0038] In this configuration, the support arm of the tilting mechanism is fixed to the lifting plate. One end is rotatably mounted on a support, while the other end is driven by a geared motor on the motor base. The connecting block on the shaft and the output shaft of the geared motor is connected to the fixing hoop. The fixing hoop secures the material cylinder via a hoop band, a locking buckle, and a locking hook. The geared motor can precisely control the tilting angle and speed of the material cylinder, facilitating the accurate pouring of the raw material from the material cylinder into the discharge cylinder. The design of the fixing hoop and the hoop band ensures a firm grip on the material cylinder. The locking buckle and locking hook are common components for connecting the hoop band. When the material cylinder is at the material loading position, the fixing hoop, the hoop band, and the locking buckle and locking hook work together to hold the material cylinder in place, with the cylinder axis vertically aligned. When material needs to be poured out, the output shaft of the geared motor drives the connecting block to rotate. The connecting block is rigidly connected to the fixing hoop, thus tilting the material cylinder.

[0039] In specific implementation, the material cylinder is provided with a feeding platform 41, the upper surface of the feeding platform is flush with the upper surface of the turntable, and a material cylinder positioning arc plate 42 is fixedly installed on the turntable.

[0040] In this way, the loading platform at the material loading position of the cylinder is flush with the turntable, facilitating the smooth transfer of the cylinder from the outside to the turntable. Forklifts can be used for handling, reducing obstacles and labor intensity during the loading process. A fixed cylinder positioning arc plate on the turntable, with the cylinder placed on both the loading platform and the turntable and its lower end in contact with the positioning arc plate, allows for precise positioning of the cylinder on the turntable. This ensures that the cylinder remains in the correct position during lifting and tilting, preventing tipping or overturning due to positional deviation, thus improving operational accuracy and safety.

[0041] In specific implementation, the fixing hoop is fixedly mounted with a column 43, and the upper end of the column is fixedly mounted with an end head 44. The end head is hinged to a hook 45. One end of the hook is used to hook with the material cylinder, and the other end of the hook is threaded to a screw 46. The inner end of the screw is positioned opposite to the column and abuts against the column. The outer end of the screw is fixed with a handle 47.

[0042] In this way, after the material cylinder is fixed by the fixing hoop and the clamp, the hook is rotated so that the inner end of the hook is inside the material cylinder. Then, the handle is rotated so that the screw is pressed against the column. At this time, the hook hooks the material cylinder. During the material cylinder turning and unloading process, the hook design can effectively prevent the material cylinder from loosening, shifting or even falling off due to gravity during the turning process, ensuring the safety and stability of the turning and unloading process.

[0043] In specific implementation, the flipping cylinder position is provided with a cylinder positioning structure for positioning the cylinder 48. The cylinder positioning structure includes two symmetrically arranged side positioning plates 49 and an end positioning plate 5. The ends of the two side positioning plates away from the end positioning plate are bent outward and extended. Both the side positioning plates and the end positioning plates are fixed to the ground by connecting columns 51.

[0044] Thus, the cylinder positioning structure at the tipping position consists of two side positioning plates and one end positioning plate, forming a U-shaped structure. The ends of the side positioning plates bend outwards to facilitate guiding the cylinder. It is fixed to the ground via connecting columns for easy installation. This system effectively positions the cylinder, ensuring it is in the correct position when the material cylinder is tipped over, allowing the raw material to be accurately poured into the cylinder, reducing spillage and waste. It also avoids operational inconvenience and safety hazards caused by cylinder positioning deviations.

[0045] Specifically, it also includes hydraulic pumps and hydraulic control systems to control the movement of hydraulic cylinders.

[0046] This material cylinder tilting and unloading device allows a single person to complete the feeding, lifting, tilting and unloading operations of the material cylinder, greatly reducing labor costs; the structure is stable and reliable, avoiding shaking and displacement during the operation of the tilting cart; compared with a robotic arm, the equipment investment cost is significantly reduced.

[0047] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
