Description

Technical Field

[0001] This utility model relates to the field of tank packaging equipment, and in particular to a tank dust cover hanging slide. Background Technology

[0002] In the secondary storage of canned milk powder, the resealable dust cap plays a crucial role. These dust caps can be made in round or square shapes and are widely used in the food industry, such as for pet food, canned nuts, potato chips, eight-treasure porridge, and milk powder packaging. Currently, resealable dust caps are mainly packaged using automated capping machines. For details, see the utility model patent application number 2012203033925, which discloses an automatic high-speed capping machine for plastic caps on canned containers. This type of capping machine uses a slide to feed the dust cap into the capping mechanism for sealing. However, a problem in the production process is that various canned products have different specifications, therefore the size of their dust caps varies, and the corresponding slide dimensions must also be adjusted. Currently, the slide is completely disassembled and replaced to match different sized dust caps, which is cumbersome and delays the production process, and needs improvement. Utility Model Content

[0020] Example 1, see appendix Figure 1-4 6. A dust cover mounting track for a tank includes a track support and two L-shaped slide rails 2 symmetrically installed within the track support. The track support includes two symmetrically arranged side guard plates 11 and a top plate 12 connecting the upper ends of the side guard plates. A capping slide rail 3 is provided directly above the two L-shaped slide rails 2. A triangular support plate 21 is provided at the upper end of the L-shaped slide rail 2, and the two triangular support plates 21 form a V-shaped inlet. The dust cover is introduced into the track through the V-shaped inlet. A seat plate is provided on the outer side of the lower end of the L-shaped slide rail 2. An L-shaped retaining rod 4 is provided on the seat plate. The upper end of the L-shaped retaining rod 4 is hinged to the seat plate, so that the L-shaped retaining rod has a certain swing space outside the L-shaped slide rail. A hanging rod 41 is provided in the middle of the 4, and a tension spring 42 is connected between the upper ends of the two hanging rods 41. The tension spring provides elastic tension to the two L-shaped clamping rods. An elastic pressure plate 5 is provided at the lower end of the cover slide rail 3, and a support slide rod 51 is provided vertically on the surface of the cover slide rail 3. The elastic pressure plate 5 is slidably connected to the support slide rod 51 through a sliding hole 52 at its end. The size of the sliding hole is larger than the cross-sectional size of the support slide rod. A limiting block 53 is provided at the upper end of the support slide rod 51, and a spring 54 is sleeved in the middle of the support slide rod 51. The elastic pressure plate 5 can slide up and down along the support slide rod 51 and has a certain swing space. The spring 54 provides elastic downward pressure for the elastic pressure plate.

[0021] An auxiliary elongated hole 55 is provided in the middle of the elastic pressure plate 5, and an auxiliary slide rod 56 is provided in the auxiliary elongated hole. A limiting block 53 is provided at the upper end of the auxiliary slide rod, and an auxiliary spring 57 is provided in the middle of the auxiliary slide rod 56. The auxiliary spring assists in pressing down the elastic pressure plate and increases its elastic downward force.

[0022] The upper end of the cover slide rail 3 is provided with a guide plate 31, which is located directly above the V-shaped inlet.

[0023] A photoelectric sensor is mounted on the bottom of the V-shaped inlet via a bracket. This photoelectric sensor monitors in real time whether a dust cover has entered the slide. If the slide is blocked, it can provide timely feedback.

[0024] In this embodiment, when the dust cover slide is in use, the dust cover enters the slide from the V-shaped inlet and slides downward. When the dust cover reaches the lower end of the slide, the inner ends of the L-shaped locking rods 4 on both sides are locked on both sides of the dust cover, blocking the slide and stopping it from sliding. At the same time, the elastic pressure plate 5 above presses on the middle of the upper surface of the dust cover. Both sides and the upper part of the dust cover are subjected to elastic pressure and are elastically pressed. When the packaging can passes through the dust cover from the conveying device, the edge of its front end can hook the inner side of the dust cover. When the tension on the dust cover is greater than the elastic pressure it receives, it is hooked, pulled out, and fastened to the upper port of the packaging can, where it is then pressed tightly by the subsequent pressing mechanism.

[0025] Example 2, see appendix Figure 3-5 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the end of the cover slide rail 3 is provided with a U-shaped seat 32, and the U-shaped seat is provided with a support rod that is fixedly connected to the top plate 12. The cover slide rail 3 is fixedly supported by the support rods at both ends. The support rod is a screw 33, which extends into the through hole in the middle of the U-shaped seat 32. Nuts 34 are provided on the screw 33 at the lower and upper parts of the U-shaped seat 32 to lock it. The height of the cover slide rail 3 is adjusted by turning the lower nut 34 to push the height of the U-shaped seat 32. After adjustment, the U-shaped seat 32 is locked by the upper nut 34.

[0026] At least two transverse guide posts 61 are provided between the lower parts of the two side guard plates 11. A folding plate 22 is provided in the middle of the L-shaped slide rail 2. The sliding sleeve 62 provided on the folding plate is slidably connected to the transverse guide posts 61, so that the two L-shaped slide rails can slide along the guide posts to adjust the spacing. An adjustment mechanism is provided between the two transverse guide posts 61. The adjustment mechanism includes a bidirectional screw 63 rotatably connected between the two side guard plates 11. A nut sleeve 64 connected to the bidirectional screw 63 is provided in the middle of the two folding plates 22. The nut sleeve 64 on one side is connected to the forward thread on the bidirectional screw 63, and the nut sleeve on the other side is connected to the reverse thread on the bidirectional screw. A handwheel 65 is provided at one end of the bidirectional screw 63.

[0027] In this embodiment, the adjustment mechanism is used by rotating the handwheel 65 to drive the bidirectional lead screw 63 to rotate. The bidirectional lead screw 63 drives the two L-shaped slide rails 2 synchronously through the nut sleeves 64 on both sides. The two L-shaped slide rails 2 slide synchronously towards or away from each other to adjust the distance between them. Tightening the nut 34 at the bottom of the U-shaped seat 32 pushes or releases the U-shaped seat 32 to adjust the height of the cover slide rail 3. After the height is adjusted to the correct position, tightening the nut 34 at the top locks the U-shaped seat 32, thereby adjusting the distance between the cover slide rail 3 and the L-shaped slide rail 2. This allows the slide rail to quickly match dust covers of different sizes, making the operation simple and convenient.
