Description

Technical Field

[0001] This invention belongs to the technical field of auxiliary equipment for lifting devices, specifically, it relates to a clutch-assisted lifting and lowering buffer device. Background Technology

[0002] For everyday disposable plastic tableware, such as disposable cups, bowls, plates, lids, and boxes, there are two main existing production methods. The first is injection molding. While injection molding fully utilizes raw materials, it suffers from high mold costs, long mold processing and debugging cycles, and the risk of missing out on market opportunities. Furthermore, the quantity and speed of each injection mold cannot compare to sheet thermoforming cup-making machines. The second method involves punching and shearing using a sheet thermoforming machine. This method uses the lifting of the lower mold and the cooperation of the upper mold to complete the product forming. However, the lifting device used in the lower mold is generally large in tonnage, thus requiring extremely high stability. To meet this requirement and reduce the failure rate of the lifting device, the industry prefers to provide auxiliary equipment to reduce damage to the lifting device itself due to its own inertia during operation.

[0003] A common auxiliary device involves adding lifting cylinders to both sides of the lifting equipment. These cylinders work simultaneously with the lifting equipment. When the lifting equipment starts, the cylinders push upwards, providing upward assistance to the lower mold of the cup-making machine, reducing resistance and energy consumption. When the lower mold descends, the cylinders release air to cushion the lower mold, preventing damage due to excessive downward inertia, and also preventing damage to the lifting body itself. While this device provides some assistance and cushioning, manufacturing errors in the cylinders can easily lead to a lack of synchronization between the two cylinders, causing misalignment of the lower mold support and increasing the product defect rate.

[0004] Therefore, in view of the problems existing in the prior art, especially the problem of the cup-making lower mold shifting under the action of auxiliary equipment, there is an urgent need to provide a device that can stably support the cup-making lower mold and provide synchronous upward assistance and downward buffer. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a clutch-assisted lifting and lowering buffer device with stable lifting support and high synchronization.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0007] A clutch-assisted lifting and lowering buffer device includes lifting support seats on the left and right sides of a lifting body supporting the device. Each of the two lifting support seats has a lifting support frame, a driven component, and a lifting component on its outer side. It also includes a lifting drive component, which is positioned away from the lifting body and its movement space. The lifting drive component is connected to the two lifting support frames via a drive shaft and drives the lifting component through the driven component. The lifting support frame has a driven connection compartment and a lifting connection compartment. The driven component is positioned between and connected to the driven connection compartment and the lifting connection compartment. The driven connection compartment connects the drive shaft to the driven component, and the lifting connection compartment connects the driven component to the lifting drive component. The two lifting components are positioned at the average lifting point of the lifting body and move accordingly with the lifting body.

[0008] Specifically, the driven assembly includes a bearing mounting base and a transmission rod. The transmission rod is fixed to the lifting support frame via the bearing mounting base. Transmission bevel gears are provided on both sides of the transmission rod, and the transmission bevel gears are respectively placed in the driven connecting compartment and the lifting connecting compartment. Drive bevel gears are provided on both sides of the drive shaft, and the drive bevel gears on both sides are respectively placed in the driven connecting compartments on both sides and mesh with the transmission bevel gears located in the driven connecting compartments. The lifting assembly includes a lifting transmission shaft that drives the lifting assembly. One side of the lifting transmission shaft is located in the lifting connecting compartment and is provided with a lifting bevel gear that meshes with the transmission bevel gears located in the lifting connecting compartment.

[0009] Preferably, the inner side of the lifting support frame is provided with a lifting movable compartment for accommodating the lifting assembly. The lifting assembly further includes a lifting rod. The other end of the lifting drive shaft passes through the lifting support frame and enters the lifting movable compartment to drive the lifting rod located in the lifting movable compartment.

[0010] More preferably, the lifting rod is provided with a lifting rack and a lifting rail on corresponding sides, and the lifting movable chamber is provided with a lifting slider that matches the lifting rail. The lifting rail and the lifting slider cooperate with each other to fix the horizontal position of the lifting rod when it is lifted. The other end of the lifting transmission shaft located in the lifting movable chamber is provided with a lifting linear gear that meshes with the lifting rack. The lifting linear gear drives the lifting rack and thus drives the lifting rod to slide up and down.

[0011] More preferably, a buffer is fixed to the upper end of the lifting rod.

[0012] Specifically, the lifting drive assembly further includes a drive source, a drive compartment, and a drive rod. The drive shaft passes through the drive compartment via a bearing seat provided in the drive compartment. The drive compartment is fixed on the equipment. The drive source is in the equipment and drives the drive rod. The drive rod enters the drive compartment and drives the drive shaft. The drive source is a motor or a cylinder.

[0013] Furthermore, the drive shaft is provided with a drive gear corresponding to the axial direction of the drive shaft at a position inside the drive compartment. The drive rod is provided with a drive rack and a drive rail. The drive compartment is provided with a drive slider that matches the drive rail. The drive rail and the drive slider cooperate with each other to fix the horizontal position of the drive rod when it is raised and lowered. The drive rack and the drive gear mesh with each other and drive the drive gear, thereby driving the drive shaft.

[0014] Preferably, the drive source is composed of a double-layer cylinder, including an upper drive cylinder and a lower drive cylinder, wherein the lower drive cylinder is used to push the upper drive cylinder, and the upper drive cylinder is used to push the drive rod.

[0015] Furthermore, the device is equipped with a support column, and the drive compartment is fixed on the support column.

[0016] The present invention has the following beneficial effects: (1) The drive shaft synchronously drives the transmission components fixed in the lifting support frame on both sides, thereby achieving the purpose of synchronously driving the lifting components, effectively improving the lifting synchronization and stability of the lifting components on both sides.

[0017] (2) By using a transmission rod for transmission and using bevel gears for meshing between the drive shaft and the transmission rod, and between the transmission rod and the lifting transmission shaft, the transmission accuracy is effectively controlled while achieving the purpose of effective transmission. The transmission rod has a stronger load-bearing capacity than the transmission belt or transmission chain, is less prone to damage, and can further ensure the synchronization of transmission on both sides.

[0018] (3) By setting a lifting rack on the lifting rod and by meshing the lifting line gear on the lifting transmission shaft with the lifting rack, the rising amplitude of the lifting rack can be precisely controlled, thereby ensuring that the lifting rods on both sides achieve precise synchronization when supporting the lower mold of the cup.

[0019] (4) A buffer is installed at the top of the lifting rod, which can effectively reduce the downward pressure when the cup mold descends. The buffering effect is further enhanced by the meshing effect of the lifting rack and the lifting line gear when the lifting rod descends. Attached Figure Description

Detailed Implementation

[0028] The present invention will now be described in detail with reference to the accompanying drawings.

[0029] Example 1:

[0030] An embodiment of the present invention provides a clutch-assisted lifting and lowering buffer device, such as... Figure 1-2As shown, the device includes a lifting body 1 with lifting support seats 2 on both sides. Each lifting support seat 2 has a lifting support frame 3, a driven component 4, and a lifting component on its outer side. It also includes a lifting drive component, which is positioned away from the lifting body 1 and its movement space. The lifting drive component connects to the lifting support frames 3 on both sides via a drive shaft 6 and drives the lifting component through the driven component 4. The lifting support frame 3 has a driven connection compartment 31 and a lifting connection compartment 32. The driven component 4 is positioned between and connected to the driven connection compartment 31 and the lifting connection compartment 32. The driven connection compartment 31 connects the drive shaft 6 to the driven component 4, and the lifting connection compartment 32 connects the driven component 4 to the lifting drive component. The lifting components on both sides are positioned at the average lifting point of the lifting body 1 and move accordingly. The drive shaft 6, which runs through both sides, is used for connection, enabling it to transmit power to the lifting components. Because the drive shaft 6 directly drives the components, the lifting components on both sides operate in perfect sync, effectively preventing tilting of the cup-making film due to asynchronous operation. Furthermore, the design of the drive shaft 4 ensures that the drive shaft 6 and the lifting drive components are positioned in a location that does not interfere with equipment operation. This effectively utilizes existing gaps in the equipment, avoiding significant modifications and saving costs and space.

[0031] Specifically, the driven assembly 4 includes a bearing mounting base 41 and a transmission rod 42. The transmission rod is fixed to the lifting support frame 3 via the bearing mounting base 41. Transmission bevel gears 43 are respectively provided on both sides of the transmission rod 42, and are respectively placed within the driven connecting chamber 31 and the lifting connecting chamber 32. Drive bevel gears 61 are provided on both sides of the drive shaft 6, and are respectively placed within the driven connecting chambers 31 on both sides and mesh with the transmission bevel gears 43 located within the driven connecting chambers 31. The lifting assembly includes a lifting transmission shaft that drives the lifting assembly. One side of the lifting transmission shaft is located within the lifting connecting chamber 32 and is provided with a lifting bevel gear 54 that meshes with the transmission bevel gear 43 located within the lifting connecting chamber 32. Using bevel gears meshing to form a right-angle transmission ensures that the one-to-one tooth-to-tooth transmission method significantly improves the accuracy of the transmission distance during operation. The bearing mounting base 41 is provided with a bearing for fixing the transmission rod 42, ensuring the stability of the transmission rod 42 during transmission.

[0032] Preferably, the inner side of the lifting support frame 3 is provided with a lifting movable chamber 33 for accommodating the lifting assembly. The lifting assembly further includes a lifting rod 5. The other end of the lifting drive shaft passes through the lifting support frame 3 and enters the lifting movable chamber 33, driving the lifting rod 5 located within the lifting movable chamber 33. The lifting movable chamber 33 can effectively fix the lifting assembly, thereby preventing the lifting assembly from shifting. More preferably, the lifting rod 5 has a lifting rack 51 and a lifting rail 52 on corresponding sides. The lifting movable chamber 33 is provided with a lifting slider 34 that matches the lifting rail 52. The lifting rail 52 and the lifting slider 34 cooperate with each other to fix the horizontal position of the lifting rod 5 during lifting. The other end of the lifting drive shaft located in the lifting movable chamber 33 is provided with a lifting linear gear 53 that meshes with the lifting rack 51. The lifting linear gear 53 drives the lifting rack 51, thereby driving the lifting rod 5 to slide up and down. When the lifting gear 53 pushes the lifting rack 51 and thus drives the lifting rod 5, since it only exerts force in one direction, it needs the cooperation of the lifting slide rail and the lifting slider 34 to provide a supporting force, thereby preventing the lifting rod 5 from tilting.

[0033] Preferably, a buffer 55 is fixed to the upper end of the lifting rod 5. The buffer 55 can provide cushioning when the cup-making lower mold descends, avoiding excessive force acting directly on the lifting rod 5 and causing damage to the lifting rod 5.

[0034] Specifically, the lifting drive assembly further includes a drive source 8, a drive chamber 7, and a drive rod 9. The drive shaft 6 passes through the drive chamber 7 via a bearing seat 71. The drive chamber 7 is fixed to the equipment. The drive source 8 is in the equipment and drives the drive rod 9. The drive rod 9 enters the drive chamber 7 and drives the drive shaft 6. In this embodiment, the drive source 8 is a motor. The drive motor directly drives the drive gear 62 of the drive shaft 6, which is located in the drive chamber 7, by means of a linear gear sleeved on the drive rod 9, thereby achieving the purpose of driving the drive shaft 6. The motor used needs to be a bidirectional motor to ensure that the gear on the drive rod 9 can rotate back and forth, thus not affecting the actual lifting effect. Alternatively, a ratchet mechanism can be used on the drive gear 62 of the drive shaft 6 to reduce the need for a motor.

[0035] Example 2:

[0036] This embodiment is basically the same as Embodiment 1, except that: Figure 3-4As shown, the drive source 8' is a cylinder. Furthermore, the drive shaft 6' is located within the drive chamber 7' and is provided with a drive gear 62' that corresponds axially to the drive shaft 6'. The drive rod 9' is provided with a drive rack 91 and a drive rail 92. The drive chamber 7' is provided with a drive slider 72 that matches the drive rail 92. The drive rail 92 and the drive slider 72 cooperate with each other to fix the horizontal position of the drive rod 9' during lifting and lowering. The drive rack 91 and the drive gear 62' mesh with each other and drive the drive gear 62' to drive the drive shaft 6'. Under normal circumstances, a screw and a motor can meet the needs of lifting assistance. However, in the descent phase, a screw would not easily achieve a smooth descent, so a ratchet is also required. In this embodiment, a cylinder is used, which avoids this problem. When rising, the cylinder supplies air to lift, thereby driving the drive shaft 6'. When descending, the cylinder releases air, which has a certain buffering effect. This ensures that the power fed back from the drive shaft 6' can make the drive rod 9' descend slowly, further playing a buffering role. At the same time, the cooperation between the drive rack and the drive gear 62' can also ensure the stability and controllability of the drive speed.

[0037] Example 3:

[0038] This embodiment is basically the same as embodiment 2, except that: Figure 5-6 As shown, preferably, the drive source 8” is composed of a double-layer cylinder, including an upper drive cylinder 81 and a lower drive cylinder 82. The lower drive cylinder 82 is used to push the upper drive cylinder 81, and the upper drive cylinder 81 is used to push the drive rod 9”. By adopting the double-layer cylinder design, the lifting and lowering rate is improved, thereby meeting the operating speed of the equipment when performing in-film labeling and ensuring normal operation.

[0039] Furthermore, the device is equipped with a support column 10, and the drive chamber 7” is fixed on the support column 10. The purpose of setting the support column 10 is to ensure that the drive chamber 7” is more stable. This is to ensure the stability of the operation of the drive chamber 7” when the drive chamber 7” is installed at a high position, and to avoid damage to the device due to insufficient strength.

[0040] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the inventive concept, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
