Description

Technical Field

[0001] The utility model relates to the technical field of single-arm hot-melt adhesive machines, in particular to a sliding drive device for a single-arm hot-melt adhesive machine. Background Art

[0002] The single-arm hot melt adhesive machine sliding drive device is used to control the sliding of the hot melt adhesive machine during operation. It usually includes components such as a servo motor, a transmission device, and a control system. It is driven by a servo motor, and the worm, lead screw, and worm gear rotate. It is a prerequisite for the hot melt adhesive machine to move smoothly and spray glue during operation.

[0003] The existing single-arm hot melt adhesive machine sliding mechanism is composed of a longitudinal sliding mechanism and a transverse sliding mechanism. The transverse sliding mechanism is mostly subjected to a large torque. When the worm connected to the servo motor shaft extension and the worm wheel on the internal lead screw of the transverse sliding mechanism are meshed for transmission, the friction between the two is large, which also causes large wear. The current method is to apply lubricating grease for regular maintenance. Due to the large loss of lubricating grease, even if it is added frequently, it is inevitable that there will be omissions and late addition of lubricating oil, resulting in serious wear of the worm and worm wheel and the need for replacement. To a certain extent, there is a high maintenance and use cost, which needs to be improved. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a single-arm hot melt adhesive machine sliding drive device, which is used to solve the problem that the worm and worm wheel of the existing single-arm hot melt adhesive machine sliding drive device are greatly worn and have high maintenance and use costs.

[0006] A single-arm hot melt adhesive machine sliding drive device, comprising a transverse sliding mechanism slidably connected to the top of the machine body, a slider slidably connected inside the transverse sliding mechanism, a screw rod drivingly connected to the slider being horizontally installed inside the transverse sliding mechanism, a worm gear being arranged at one end of the screw rod, a servo motor corresponding to the position of the worm gear being arranged on the transverse sliding mechanism, and the servo motor being drivingly connected to a worm gear meshing with the worm gear above the worm gear inside the transverse sliding mechanism;

[0007] A partition plate movably sleeved on the surface of the screw is vertically arranged on the side of the lateral sliding mechanism close to the worm gear, and the partition plate and the lateral sliding mechanism form an oil storage tank containing the worm gear and the worm. A guide plate is arranged on one side of the partition plate and below the worm gear inside the lateral sliding mechanism, and the height of the guide plate close to the partition plate is greater than the height of the side away from the partition plate. An oil drain port is arranged on the lower side of the guide plate of the lateral sliding mechanism, and a sealing plug is arranged in the oil drain port.

[0008] Preferably, a sealing member is provided at a position of the partition plate corresponding to the screw rod.

[0009] Preferably, an oil guide groove is provided on the upper slope surface of the guide plate.

[0010] Preferably, the transverse sliding mechanism is provided with an oil tank cover located above the worm gear and the partition plate.

[0011] Preferably, the upper surface of the oil tank cover is also provided with a glass observation window and a handle.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model provides a partition plate, a guide plate and an oil drain port, and adds lubricating grease to an oil storage tank formed by the partition plate and a horizontal sliding mechanism to soak the worm wheel and the worm, thereby reducing the wear between the worm and the worm wheel, improving the lubricity between the two, and extending the service life and maintenance cycle. At the same time, the remaining amount of lubricating grease can be timely observed through the glass observation window, which is convenient for timely addition. There is no need to add lubricating grease frequently, thus shortening the maintenance time and reducing the cost of replacing the worm wheel and the worm, and solving the problem that the worm and the worm wheel of the existing single-arm hot melt adhesive machine sliding drive device have large wear and tear and high maintenance and use costs.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1-2As shown, the utility model provides a technical solution: a single-arm hot melt adhesive machine sliding drive device, including a transverse sliding mechanism 101 slidably connected to the top of a body 1, the transverse sliding mechanism 101 is provided with an oil tank cover 7 located above a worm gear 104 and a partition plate 2 to prevent internal lubricating grease from splashing out and prevent dust from entering, a slider 102 is slidably connected inside the transverse sliding mechanism 101, a screw rod 103 transmission-connected to the slider 102 is horizontally installed inside the transverse sliding mechanism 101, a worm gear 104 is provided at one end of the screw rod 103, a servo motor 105 corresponding to the position of the worm gear 104 is provided on the transverse sliding mechanism 101, and the servo motor 105 is transmission-connected to a worm gear 106 above the worm gear 104 inside the transverse sliding mechanism 101 and meshing with the worm gear 104.

[0019] A partition plate 2 movably sleeved on the surface of the screw rod 103 is vertically arranged on one side of the transverse sliding mechanism 101 near the worm gear 104. The partition plate 2 and the transverse sliding mechanism 101 form an oil storage tank containing the worm gear 104 and the worm rod 106. A seal 6 is arranged at the position of the partition plate 2 corresponding to the screw rod 103, and a glass observation window and a handle are also arranged on the upper surface of the oil tank cover 7.

[0020] The interior of the transverse sliding mechanism 101 is provided with a guide plate 3 located on one side of the partition plate 2 and below the worm 106, so as to facilitate the lubricating grease to flow out to the side of the oil drain port 4.
