Description

Technical Field

[0001] This invention relates to processing equipment for thermos cups, and more particularly to a rack and pinion transmission mechanism for transferring the thermos cup body between multiple sealable chambers. Background Technology

[0002] Existing rack and pinion mechanisms generally involve continuous contact between the rack and gears, minimizing vibration issues. However, in special cases, such as the continuous vacuuming process for multi-chamber thermos cups, the vacuuming equipment has multiple sealable chambers. The conveyor rack needs to transport the thermos cup body from one chamber to an adjacent chamber. In this situation, the rack below the conveyor rack and the gears in each chamber may disengage and re-engage. During re-engagement, due to the uncertainty in the orientation of the gear teeth, they often cannot fully mesh initially, causing strong impacts and vibrations (vibration) until they fully mesh. This vibration can cause the solder on the vacuum holes of the thermos cup body on the conveyor rack to fall off. Therefore, improvements are needed to eliminate this vibration. Summary of the Invention

[0003] The purpose of this invention is to provide a rack and pinion transmission mechanism for transferring the body of a thermos cup between multiple sealable chambers, which solves the vibration problem during the meshing process of the rack and transmission gear, and prevents the solder on the vacuum hole of the thermos cup body from falling off due to vibration.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rack and pinion mechanism for transferring thermos cup bodies between multiple sealable chambers includes a shelf for holding thermos cup bodies to be transferred. The shelf is mounted on a track via rollers. A rack is located at the bottom of the shelf, and multiple transmission gears that can mesh with the rack are arranged along the rack's travel path. Each transmission gear is mounted on a corresponding transmission shaft, and each transmission shaft is equipped with a seesaw that serves as its rotation fulcrum. Each seesaw consists of a connecting rod, a fixed plate on the front side of the connecting rod, and a counterweight on the rear side of the connecting rod. A positioning gear of the same specification as the transmission gear is provided on the fixed plate on the front side of the transmission gear, and an auxiliary gear that meshes with both is provided on the fixed plate at the lower center of the transmission gear and the positioning gear. In the initial state, the counterweight is sunk to the bottom of the sealable chamber, and the front of the seesaw is raised so that the top of the positioning gear is 3-5 mm higher than the top of the transmission gear. When the rack at the bottom of the shelf moves from front to back, it first meshes with the rotating positioning gear, and then with the rotating transmission gear.

[0006] The bottom of the counterweight is screwed with a positioning rod, and the lower part of the positioning rod is movably inserted into a blind hole located at the corresponding position in the sealable chamber.

[0007] The drive shaft is supported on a mounted bearing.

[0008] In the initial state, the top of the positioning gear is 5 mm higher than the top of the transmission gear.

[0009] Compared with the prior art, the beneficial effects of the present invention are: due to the adoption of the above technical solution,

[0010] By default, in the initial state (without rack engagement), the positioning gear is 3-5mm higher than the drive gear, ensuring that the positioning gear contacts the rack first. The rack of the shelf is transported from one sealable chamber to an adjacent sealable chamber, and the rack contacts the positioning gear first. The positioning gear is then pressed down (the counterweight rises), and the positioning gear and rack are fully engaged during the pressing process. During this process, the downward movement of the front side of the seesaw acts as a buffer for the rack pressing down on the positioning gear, resulting in no impact on the shelf. Since the positioning gear and drive gear are linked through an auxiliary gear, the rack can also achieve full engagement with the drive gear afterward without any impact. This solves the vibration problem during the engagement process of the rack and drive gear, and the solder on the vacuum hole of the thermos cup will not fall off due to vibration.

Detailed Implementation

[0019] To make the technical solution of the present invention clearer, the following description is provided in conjunction with the appendix. Figures 1 to 6 This invention will be described in detail below. It should be understood that the specific embodiments described in this specification are merely for explaining the invention and are not intended to limit the scope of protection of the invention.

[0020] This invention relates to a rack and pinion mechanism for transferring insulated cup bodies between multiple sealable chambers. It includes a shelf 6 for holding the insulated cup bodies 7 to be transferred. The shelf 6 is mounted on a track 9 via rollers 8. A rack 2 is located at the bottom of the shelf 6, and multiple transmission gears 1-1 that mesh with the rack 2 are arranged along its travel path. Each transmission gear 1-1 is mounted on a corresponding transmission shaft 3. Each transmission shaft 3 is equipped with a seesaw 1 that serves as its fulcrum. Each seesaw 1 consists of a connecting rod 1-7, a fixing plate 1-5 on the front side of the connecting rod 1-7, and a counterweight 1-6 on the rear side of the connecting rod 1-7. A positioning gear 1-2 of the same specification as the transmission gear 1-1 is provided on the fixing plate 1-5 on the front side of the transmission gear 1-1. An auxiliary gear 1-3 that meshes with both is provided on the fixing plate 1-5 at the lower center of the transmission gear 1-1 and the positioning gear 1-2. In the initial state, the counterweight 1-6 sinks to the bottom of the sealable chamber 4, and the front of the seesaw 1 is raised so that the top of the positioning gear 1-2 is 3-5 mm higher than the top of the transmission gear 1-1. When the rack 2 at the bottom of the shelf 6 moves from front to back, it first meshes with the rotating positioning gear 1-2, and then meshes with the rotating transmission gear 1-1.

[0021] Preferably, the drive shaft 3 is supported on a bearing 3-1, which is mounted on a support block 3-2. In the initial state, the top of the positioning gear 1-2 is preferably 5 mm higher than the top of the drive gear 1-1.

[0022] Preferably, the upper end of the positioning rod 1-8 is screwed or snapped to the lower part of the counterweight 1-6, and the lower part of the positioning rod 1-8 is movably inserted into the blind hole 5 located at the corresponding position in the sealable chamber 4. By default, without the rack 2 engaged, due to the action of the counterweight 1-6, the lower end of the positioning rod 1-8 contacts the bottom of the blind hole 5. By adjusting the length of the positioning rod 1-8 outside the counterweight 1-6 (if the upper end of the positioning rod 1-8 is screwed to the lower part of the counterweight 1-6, it can be adjusted by rotating the positioning rod 1-8), the height of the positioning gear 1-2 above the transmission gear 1-1 can be adjusted.
