[0002] Currently, the transmission system of continuous vacuum equipment for thermos cups, taking a three-chamber furnace as an example, uses a feeding cart to deliver the material tray between furnace bodies, and a cylinder-driven transmission method between furnace bodies.

When a chain drive is used for a continuous furnace with more than three chambers, the transmission position is inaccurate, and the material tray will shake when the equipment stops during the transmission process. To avoid the above defects, this type of transmission system was developed. Utility Model Content

It is easy to understand that the clutch assembly 700 has the same structure and is respectively provided on the drive shaft mechanism 200 and the driven shaft mechanism 300. Specifically, it includes a coupling 701, a connecting cover 702 and a clutch 703.

[0034] The clutch assembly 700 located in the drive shaft mechanism 200 has the following structure: the coupling 701 is used for power transmission between the main drive shaft 202 and the connecting cover 702, the connecting cover 702 is mounted on the clutch 703, and the clutch 703 is mounted on the drive shaft 205;

[0035] The clutch assembly 700 is located in the drive shaft mechanism 300 with the following structure: the coupling 701 is used for power transmission between the drive shaft 302 and the connecting cover 702, the connecting cover 702 is mounted on the clutch 703, and the clutch 703 is located on the drive shaft 304.

[0036] In this embodiment, both the drive shaft mechanism 200 and the driven shaft mechanism 300 are provided with fixing components 800. The fixing components 800 include a spherical bearing seat 801, a tapered roller bearing 802, a bearing seat 803, a spacer 804, and a locking nut 805.

[0037] Similarly, in the main drive shaft mechanism 200, the two ends of the main drive shaft 202 are provided with spherical bearing seats 801 for supporting and fixing them.

[0038] Located in the drive shaft mechanism 300, the two ends of the drive shaft 302 are provided with spherical bearing seats 801 for supporting and fixing them. The bearing seats 803 are used for axial support of the drive shaft 304, and tapered roller bearings 802 are installed at both ends. The rear end of the drive shaft 304 is provided with a spacer 804 and a locking nut 805 in sequence.

[0039] Furthermore, in order to achieve speed reduction by realizing gear transmission at each stage, the drive shaft mechanism 200 is provided with a speed reduction assembly 900. The speed reduction assembly 900 includes a speed reducer 901, a speed reducer base 902, a speed reducer mounting plate 903, a drive synchronous pulley 904, and a short synchronous belt 905.

The reducer 901 is installed on the reducer mounting plate 903. The drive synchronous pulley 904 is installed on the shaft of the reducer 901. The servo motor 204 is installed on the end face stop of the reducer 901.

[0041] Furthermore, in this embodiment, to ensure the vacuum level of the furnace body 100 in the vacuum chamber, the furnace body main shaft mechanism 400 is provided with the following components in sequence from top to bottom: a dust seal 404, a dust cover 405, a deep groove ball bearing 406, a skeleton oil seal 407, a spacer 408, an O-ring 409, a bearing sleeve 410, an angular contact ball bearing 411, a pressure cap 412, a sealing spacer 413, a sensor 414, a sensor base 415, a sensing rod 416, a threaded nut 417, and a sensing plate 418.

The servo motor 204 and motor base are located on the side of the furnace body 100, which takes up less space and is convenient for maintenance. The main drive shaft 202 is located at the bottom of the outer side of the furnace body 100, which reduces the instability of transmission caused by the thermal deformation of the main drive shaft 202.

[0043] The drive shaft mechanism 300 is also located on the side of the furnace body 100, and the transmission shaft 302 is located at the bottom of the outer side of the furnace body 100.

[0045] The furnace body 100's main shaft mechanism 400 is equipped with a bevel gear 403 and a spur gear 401. The main bevel gear 201 on the main power shaft mechanism 200 transmits power to the driven bevel gear 301 on the main shaft mechanism of the furnace body 100, thereby transmitting power to the spur gear 401, which drives the rack 101a mounted on the material tray 101 to move together inside the furnace body 100. A sensor 414 is installed on the bottom surface of the furnace body 100 to ensure that the spur gear 401 on the main shaft mechanism of the furnace body 100 stops at a uniform position after each rotation, so that the rack 101a on the material tray 101 can accurately engage with the spur gear 401 each time.

[0046] Example 2

[0047] This embodiment describes the installation process of various components of a continuous vacuum equipment transmission system for thermos cups, specifically including a main drive shaft mechanism 200, a driven drive shaft mechanism 300, a tensioning wheel mechanism 500, and a furnace body main shaft mechanism 400.

[0048] Specifically, the main bevel gear 201 is mounted on the main drive shaft 202. A spherical bearing housing 801 is installed at each end of the main drive shaft 202 to support it. A coupling 701 connects the main drive shaft 202 to the connecting cover 702 for power transmission. The connecting cover 702 is mounted on the clutch 703, which is located on the drive shaft 205. A tapered roller bearing 802 is installed at each end of the bearing housing 803.

A reducer 901 is mounted on the reducer mounting plate 903. A drive synchronous pulley 904 is mounted on the shaft of the reducer 901. A servo motor 204 is mounted on the end face stop of the reducer 901.

[0049] The bevel gear 301 is mounted on the driven shaft 302. A spherical bearing housing 801 is provided at each end of the driven shaft 302 to support the driven shaft 302. The coupling 701 connects the driven shaft 302 and the connecting cover 702 to transmit power. The connecting cover 702 is mounted on the clutch 703, which is located on the driven power shaft 304. A tapered roller bearing 802 is installed at each end of the bearing housing 803. A spacer 804, a driven synchronous pulley 303, and a lock nut 805 are arranged sequentially at the rear end of the driven power shaft 304.

[0050] Tensioner seat 501 is located on the side of bearing seat 803 of drive shaft mechanism 300. Tensioner shafts 505 are mounted on the left and right sides of the lower side of tensioner seat 501, and each tensioner shaft 505 is equipped with a tensioner 506. Adjusting screw mounting plate 503 is located on tensioner seat 501, and adjusting screws 502 are mounted on the top of adjusting screw mounting plate 503 for adjusting the tension of long synchronous belt 102.

Idler synchronous pulley 507 is mounted on idler synchronous pulley shaft 508.

[0051] A spur gear 401 is located at the top of the gear shaft 402 inside the furnace body 100, and is used for the movement of the material tray 101 inside the furnace body 100. A dust seal 404 is located inside the dust cover 405 to prevent dust from entering the bearing sleeve 410 and affecting the service life of the bearing. Three skeleton oil seals 407 and O-rings 409 are located on the transmission shaft to ensure the sealing of the furnace body main shaft mechanism 400 and to ensure the vacuum degree of the furnace body 100 in the vacuum chamber. The cooperation of angular contact ball bearings 411 and deep groove ball bearings 406 supports the gear shaft 402 and ensures that the gear shaft 402 is accurately positioned and does not produce axial movement. A bevel gear 403 is located at the end of the gear shaft 402 to transmit power to the spur gear 401. A sensing plate 418 is located at the rear end of the bevel gear. A sensing rod 416 is installed on the sensing plate 418. A sensor 414 is installed on the sensor 414 seat. The cooperation of the sensing rod 416 and the sensor 414 ensures the accuracy of the gear transmission stop position.

[0052] Furthermore, the transmission process of the material tray 101 in the transmission system of the continuous vacuum equipment for thermos cups proposed in this embodiment within each furnace body 100, taking the material tray 101 reaching the set height of the lifting rack as an example, specifically includes the following steps:

[0053] S1: Before the material tray 101 enters the furnace body 100, the sensing rod 416 and sensor 414 work together to first rotate the spur gear 401 to a specified angle and stop, ensuring the gear stops accurately so that the rack 101a installed at the bottom of the material tray 101 can correctly mesh with the gear when it moves over. Two sets of through-beam sensing mechanisms 600 are installed on the outside of each furnace body 100. The first set of through-beam sensing mechanisms 600 ensures that the rack 101a on the material tray 101 meshes correctly with the spur gear 401 on the gear shaft 402 under the action of the drive shaft mechanism 200. The second set of through-beam sensing mechanisms 600 ensures that the rack 101a on the material tray 101 meshes correctly with the spur gear 401 on the gear shaft 402 under the action of the driven shaft mechanism 300, and determines the stopping position of the material tray 101 inside the furnace body 100, preparing for vacuum heating.

[0054] S2: When the material tray 101 reaches the first set of photoelectric sensor mechanisms 600, the lifting material rack stops conveying the material tray 101 into the furnace body 100. The rack 101a on the material tray 101 and the spur gear 401 on the first set of main shaft mechanisms of the furnace body 100 are correctly engaged. At this time, the servo motor 204 is powered on, and the clutch 703 on the drive shaft mechanism 200 is engaged. The servo motor 204 transmits power to the reducer 901, which then transmits power through the drive synchronous pulley 904 on the reducer 901. Power is transmitted via a long synchronous belt 102 to a double synchronous pulley 203, which together drive the main drive shaft 205, clutch 703, connecting cover 702, coupling 701, main drive shaft 202, and main bevel gear 201 to rotate. The main bevel gear 201 transmits power to bevel gear 403, which then transmits power to the rack 101a mounted at the bottom of the material tray 101 via the gear shaft 402 and spur gear 401. The rack 101a then drives the material tray 101 to move together.

[0055] S3: When the material tray 101 reaches the second set of photoelectric sensor mechanism 600, the material tray 101 stops moving inside the furnace body 100. The material tray 101 reaches the predetermined position inside the furnace body 100, and the rack 101a on the material tray 101 and the spur gear 401 on the second set of main shaft mechanism inside the furnace body 100 enter the correct meshing state. At this time, the servo motor 204 is de-energized, and the clutch 703 on the main drive shaft mechanism 200 is released; the furnace door 103 and the slide valve 104 are closed, and the vacuuming and heating state is entered.

[0056] S4: When the furnace body 100 reaches the set heating time and vacuum level, the slide gate valve 104 opens, the servo motor 204 is powered on, and the clutch 703 on the drive shaft mechanism 300 engages. The servo motor 204 transmits power to the reducer 901, which in turn transmits the power via the drive synchronous pulley 904 on the reducer 901 to the double synchronous pulley 203 via the short synchronous belt 905. The double synchronous pulley 203 and the long synchronous belt 102 drive the driven synchronous pulley 303 to rotate. The driven synchronous pulley 303 together drive the driven drive shaft 304, clutch 703, connecting cover 702, coupling 701, driven transmission shaft 302, and main bevel gear 201 to rotate. The main bevel gear 201 transmits power to the bevel gear 403, which in turn transmits power to the rack installed at the bottom of the material tray 101 via the gear shaft 402 and the spur gear 401. 101a, the rack 101a drives the material tray 101 to move together into the second furnace body 100; when it reaches the first set of photoelectric sensor mechanisms 600 in the second furnace body 100, the material tray 101 stops conveying, at this time the servo motor 204 is de-energized and disengaged from the clutch 703 on the power shaft mechanism 300; the rack 101a on the material tray 101 and the spur gear 401 on the first set of main shaft mechanism in the second furnace body 100 enter the correct meshing state, at this time the servo motor 204 on the second furnace body 100 is energized, the clutch 703 on the main power shaft mechanism 200 on the second furnace body 100 is engaged, the transmission system on the second furnace body 100 repeats the above actions, and completes the corresponding heating temperature and vacuum degree in each furnace body 100 in sequence, until the cup on the material tray 101 completes the vacuuming work and is sent out of the furnace body 100.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the scope of protection of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description and ideas.
