[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5As shown in the figure, the pushing mechanism for the palletizer includes a base 1. A conveying mechanism 2 is movably installed on the left side of the base 1. Four vertically distributed立杆3 are fixedly connected to the front and rear sides of the upper side of the base 1 near the right side. A plurality of vertically distributed limiting holes 4 are formed on the outer sides of the four立杆3 away from each other. A pushing mechanism 5 is movably sleeved on the outer side of the立杆3. Two fixing mechanisms 6 symmetrically distributed in the front and back are fixedly connected to the position near the left side of the pushing mechanism 5.

[0027] The pushing mechanism 5 includes a push plate 51. The left sides of the fixing mechanisms 6 are fixedly connected to the positions near the front and back sides of the right side of the push plate 51. A sliding frame 52 is fixedly connected to the middle of the right side of the push plate 51. Two fixing platforms 53 symmetrically distributed in the front and back are slidably connected to the front and back sides of the sliding frame 52. The outer sides of the fixing platforms 53 away from each other are movably sleeved on the outer side of the立杆3. Two hydraulic push rods 55 are fixedly connected to the inner sides of the two fixing platforms 53. Two limiting components 54 symmetrically distributed in the left and right are fixedly connected to the positions near the left and right sides of the outer sides of the two fixing platforms 53 away from each other.

[0028] It should be noted that the fixing mechanism 6 is used to connect the push plate 51 and the hydraulic push rod 55 together. The hydraulic push rod 55 can control its own length, causing the hydraulic push rod 55 to drive the push plate 51 to move left and right, so that the push plate 51 pushes the material. The limiting component 54 and the limiting hole 4 cooperate to fix the fixing platform 53 in the limiting holes 4 at different horizontal heights to adjust the height of the fixing platform 53.

[0029] As Figure 4 shown, the limiting component 54 includes a mechanism seat 541. The side of the mechanism seat 541 close to the push plate 51 is fixedly connected to the side of the fixing platform 53 away from the sliding frame 52. An insertion block 542 is movably sleeved inside the mechanism seat 541. The outer side of the insertion block 542 close to the sliding frame 52 is movably sleeved inside the limiting hole 4. The side of the insertion block 542 away from the sliding frame 52 is rotatably connected to a pull rod 544 through a round shaft. The outer side of the pull rod 544 away from the sliding frame 52 is movably sleeved inside the inner wall of the side of the mechanism seat 541 away from the push plate 51. A first spring 543 is movably sleeved inside the mechanism seat 541, and the first spring 543 is located on the side of the insertion block 542 away from the sliding frame 52.

[0030] It should be noted that when the insertion block 542 is inside the limiting hole 4, the position of the fixing platform 53 is fixed. The first spring 543 pushes the insertion block 542, so that the insertion block 542 will not automatically脱离 the inside of the limiting hole 4 without being affected by humans. Pull the pull rod 544, causing the insertion block 542 to脱离 the limiting hole 4, so that the fixing platform 53 can quickly move up and down on the立杆3.

[0031] As Figure 4 shown, the shape of the pull rod 544 is in the shape of a Chinese character 'zhong'.

[0032] It should be noted that the shape of the pull rod 544 causes it to rotate when it is pulled out of the inner side of the mechanism seat 541, so that the pull rod 544 can no longer enter the inner side of the mechanism seat 541, thus preventing the first spring 543 from resetting the insert block 542.

[0033] like Figure 2 As shown, a rubber pad is fixedly connected to the left side of the push plate 51.

[0034] It should be noted that the rubber pad is used to prevent rigid contact between the push plate 51 and the pushed material, which could cause wear on either the push plate 51 or the material.

[0035] like Figure 3 , Figure 5 As shown, the fixing mechanism 6 includes a card holder 61. The left side of the card holder 61 is fixedly connected to the right side of the push plate 51 near the front and rear sides. The outer side of the hydraulic push rod 55 is movably sleeved on the inner side of the card holder 61 near the left side. Several annularly distributed balls 62 are movably sleeved on the inner side of the side wall of the card holder 61 near the left side. The outer side of the card holder 61 is rotatably connected to a limiting sleeve 63. Several annularly distributed ball grooves 64 are opened on the inner side of the limiting sleeve 63.

[0036] It should be noted that the outer side of the ball 62 is movably sleeved in the groove near the left side of the hydraulic push rod 55. When the ball groove 64 is misaligned with the position of the ball 62, the ball 62 cannot move, causing the ball 62 to be stuck in the groove and unable to move, thus fixing the push plate 51 and the hydraulic push rod 55. Rotating the limiting sleeve 63 aligns the ball groove 64 with the ball 62, allowing the ball 62 to move, thereby allowing the push plate 51 and the hydraulic push rod 55 to separate.

[0037] like Figure 5 As shown, a second spring 66 is movably installed between the inner side of the limiting sleeve 63 and the outer side of the card seat 61.

[0038] It should be noted that the second spring 66 is a torsion spring. The second spring 66 is used to stabilize the state of the limiting sleeve 63, so that the limiting sleeve 63 will not rotate on its own without human intervention. At the same time, in the initial state, the ball groove 64 and the ball 62 are offset from each other.

[0039] like Figure 5 As shown, a transmission sleeve 65 is movably sleeved on the outer side of the limiting sleeve 63, and several annularly distributed limiting grooves 67 are provided on the outer side of the card seat 61 near the right side. The protrusion on the inner side of the right wall of the transmission sleeve 65 is slidably connected to the inner side of the limiting groove 67.

[0040] It should be noted that a retaining strip is provided between the transmission sleeve 65 and the limiting sleeve 63 for limiting, so that the transmission sleeve 65 and the limiting sleeve 63 will not rotate relative to each other. When the transmission sleeve 65 is rotated, the transmission sleeve 65 drives the limiting sleeve 63 to rotate. The limiting groove 67 is L-shaped, so that the transmission sleeve 65 can slide to the right after rotating, thus fixing the transmission sleeve 65 and preventing the second spring 66 from driving the limiting sleeve 63 to reset.

[0041] The working principle of this utility model is as follows: First, the fixing mechanism 6 connects the push plate 51 and the hydraulic push rod 55 together. The hydraulic push rod 55 can control its own length, causing the hydraulic push rod 55 to drive the push plate 51 to move left and right, so that the push plate 51 pushes the material. The limiting component 54 cooperates with the limiting hole 4, so that the fixing platform 53 is fixed in the limiting hole 4 at different horizontal heights, thereby adjusting the height of the fixing platform 53. When the insert block 542 is located inside the limiting hole 4, the position of the fixing platform 53 is fixed, and the first spring 543 pushes the insert block 542, so that the insert block 542 will not detach from the limiting hole 4 on its own without human intervention. On the inside, pulling the lever 544 causes the insert block 542 to disengage from the limiting hole 4, allowing the fixed platform 53 to move quickly up and down on the upright 3. The limiting component 54 fixes the horizontal position of the push plate 51. Then, by adjusting the insert block 542 and inserting it into the limiting holes 4 at different heights, the height of the push plate 51 can be quickly adjusted. This allows the push plate 51 to provide a reasonable force application position when facing materials of different heights that need to be stacked, making the material movement more stable when the push plate 51 pushes the material. Finally, a locking strip is provided between the transmission sleeve 65 and the limiting sleeve 63 for limiting, ensuring that the transmission sleeve 65 and... There is no relative rotation between the limiting sleeves 63. Rotating the transmission sleeve 65 causes the limiting sleeve 63 to rotate. The limiting groove 67 is L-shaped, allowing the transmission sleeve 65 to slide to the right after rotation, thus fixing the transmission sleeve 65 and preventing the second spring 66 from resetting the limiting sleeve 63. The second spring 66 is a torsion spring, used to stabilize the state of the limiting sleeve 63, preventing it from rotating on its own without human intervention. In the initial state, the ball groove 64 and the ball 62 are offset from each other, and the outer side of the ball 62 is movably sleeved on the outer side of the hydraulic push rod 55 near the left. When the ball groove 64 and the ball 62 are misaligned in the side slot, the ball 62 cannot move, causing it to be stuck in the slot and fixed. This fixes the push plate 51 and the hydraulic push rod 55. Rotating the limiting sleeve 63 aligns the ball groove 64 with the ball 62, allowing the ball 62 to move and thus separating the push plate 51 and the hydraulic push rod 55. The ball 62 fixes the push plate 51 and the hydraulic push rod 55. Rotating the transmission sleeve 65 allows the push plate 51 and the sliding frame 52 to be quickly removed from the hydraulic push rod 55 and the fixed platform 53, enabling quick maintenance of this component. It is easy to install and disassemble.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
