Description

Technical Field

[0001] The utility model relates to the field of blocking devices, in particular to a lateral transmission blocking device. Background Art

[0002] When the double-speed chain conveyor line is conveying pallets, a blocking device is required to intermittently block the pallet from moving forward. The blocking device includes a blocking seat and a cylinder that drives the blocking seat to rise and fall. Traditionally, the cylinder is directly set under the blocking seat to control the lifting of the blocking seat.

[0003] However, for a double-speed chain conveyor line that is narrow and has no space at the bottom, it is not convenient to install a cylinder under the blocking seat. Therefore, a blocking device with a lateral transmission assembly is needed that can adapt to a double-speed chain conveyor line that is narrow and has no space at the bottom. Utility Model Content

One end of the pull rod is connected to the piston rod of the cylinder through the auxiliary plate, and the other end of the pull rod is movably connected to the lifting seat through the connecting rod assembly.

[0008] When the pull rod slides toward the direction approaching the lifting seat, the lifting seat and the blocking seat rise until the blocking seat can block the passage of the pallet; when the pull rod slides toward the direction away from the lifting seat, the lifting seat and the blocking seat descend until the pallet can pass over the blocking seat.

[0009] Preferably, a receiving space is provided at the bottom of the lifting seat, and the connecting rod assembly is located in the receiving space;

[0011] When the pull rod slides towards the lifting seat until the angle between the first connecting rod and the second connecting rod is 180 degrees, the lifting seat rises with the blocking seat until the blocking seat can block the tray from passing through;

[0012] When the pull rod slides away from the lifting seat until the angle between the first connecting rod and the second connecting rod is less than 180 degrees, the lifting seat descends with the blocking seat until the tray can pass above the blocking seat.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] The embodiment of the present application discloses a lateral transmission blocking device.

[0029] Reference Figure 1-3 The lateral transmission blocking device includes a blocking seat 1, a driving mechanism 2 for driving the blocking seat 1 to rise and fall, and a mounting plate 3 for mounting the driving mechanism 2.

[0030] The blocking seat 1 includes a base 11 and a swing rod 12. The base 11 is in an "丄" shape. The position of the swing rod 12 near the middle is hinged to the vertical section of the base 11, dividing the swing rod 12 into a first section body 121 and a second section body 122. The length of the first section body 121 is greater than that of the second section body 122. Under the action of gravity, the first section body 121 descends, causing the second section body 122 to rise, and the tray moves along the direction from the second section body 122 to the first section body 121.

[0031] Pulley 13 is rotatably connected to both ends of the swing rod 12. One pulley 13 is arranged on each side of each end of the swing rod 12. The pulley 13 abuts against the bottom surface of the tray. When the tray passes through the blocking seat 1, the bottom surface of the tray abuts against the outer peripheral wall of the pulley 13, improving the smoothness of the tray passing through the blocking seat 1.

[0032] The driving mechanism 2 includes a pull rod 21, a cylinder 22 and a first guiding component 23. The pull rod 21 is located on one side of the blocking seat 1 in the width direction. The cylinder 22 is located on the side of the pull rod 21 away from the blocking seat 1. The cylinder 22 drives the pull rod 21 to slide along the width direction of the blocking seat 1. The first guiding component 23 is used to guide the pull rod 21 to slide only along the width direction of the blocking seat 1.

[0033] A lifting seat 4 is fixed below the blocking seat 1. A second guiding component 5 is arranged on the lifting seat 4. The second guiding component 5 is used to guide the lifting seat 4 to slide only in the vertical direction. One end of the pull rod 21 is connected to the piston rod of the cylinder 22 through an auxiliary plate 6, and the other end of the pull rod 21 is movably connected to the lifting seat 4 through a connecting rod assembly 7.

[0034] When the pull rod 21 slides towards the direction close to the lifting seat 4, the lifting seat 4 carries the blocking seat 1 up until the blocking seat 1 can block the tray from passing through. When the pull rod 21 slides towards the direction away from the lifting seat 4, the lifting seat 4 carries the blocking seat 1 down until the tray can pass through above the blocking seat 1, which can adapt to the narrow and bottomless space double-speed chain conveyor line.

[0035] A receiving space 41 is arranged at the bottom of the lifting seat 4. The connecting rod assembly 7 is located in the receiving space 41.

[0036] The connecting rod assembly 7 includes a first connecting rod 71, a second connecting rod 72 and a third connecting rod 73. One end of the first connecting rod 71 is hinged to the end of the pull rod 21 away from the cylinder 22. The other end of the first connecting rod 71 is simultaneously hinged to the top end of the second connecting rod 72 and the bottom end of the third connecting rod 73. The bottom end of the second connecting rod 72 is hinged to the inner wall of the receiving space 41. The top end of the third connecting rod 73 is hinged to the inner wall of the receiving space 41.

[0037] When the pull rod 21 slides towards the direction close to the lifting seat 4 until the angle between the first connecting rod 71 and the second connecting rod 72 is 180 degrees, the lifting seat 4 carries the blocking seat 1 up until the blocking seat 1 can block the tray from passing through.

[0038] When the pull rod 21 slides in a direction away from the lifting seat 4 until the angle between the connecting rod 1 71 and the connecting rod 2 72 is less than 180 degrees, the lifting seat 4 and the blocking seat 1 are lowered until the tray can pass over the blocking seat 1 .

[0039] A C-shaped mounting bracket 31 is provided on the side of the mounting plate 3 away from the blocking seat 1. The cylinder body of the cylinder 22 is provided on the outer wall of the middle section of the mounting bracket 31. The piston rod of the mounting bracket 31 passes through the wall of the middle section of the mounting bracket 31. The auxiliary plate 6 is located in the space enclosed by the mounting bracket 31. The side of the auxiliary plate 6 away from the pull rod 21 is fixedly connected to the piston rod of the cylinder 22.

[0040] Guide assembly 1 23 includes guide cylinder 1 231, guide cylinder 2 232, and guide rod 233. Both guide cylinder 1 231 and guide cylinder 2 232 are fixed to mounting plate 3. One end of guide rod 233 is fixedly connected to auxiliary plate 6, while the other end of guide rod 233 passes through guide cylinder 2 232 and is slidably connected thereto. The end of pull rod 21 away from blocking seat 1 passes through guide cylinder 1 231 and is slidably connected thereto. Auxiliary plate 6 is vertically arranged, with guide rod 233 and pull rod 21 connected to both ends of the auxiliary plate 6 along its length. Guide cylinder 1 231 allows pull rod 21 to slide only along the width of blocking seat 1. The cooperation between guide cylinder 2 232 and guide rod 233 improves the sliding stability of pull rod 21.

[0041] Guide assembly 2 5 includes guide plates 51, which are fixedly connected to both ends of the lift base 4 in the longitudinal direction. Guide rails are provided within the double-speed chain conveyor line to guide the lifting and lowering of the lift base 4. The guide rails correspond one-to-one with the guide plates 51 and are provided with guide grooves for the guide plates 51 to move upward and downward. Reinforcing ribs 52 are provided below the guide plates 51. The reinforcing ribs 52 are fixedly connected to the bottom surface of the guide plates 51 and the outer wall of the lift base 4 to enhance the structural strength between the guide plates 51 and the lift base 4.

[0042] The implementation principle of a lateral transmission blocking device in the embodiment of the present application is as follows:

[0043] When it is necessary to block the pallet, the cylinder 22 pushes the pull rod 21 to slide toward the lifting seat 4 until the angle between the connecting rod 1 71 and the connecting rod 2 72 is 180 degrees, the blocking seat 1 rises to block the pallet, the rocker arm 12 tilts, and the second section 122 rises and is located above the first section 121, thereby blocking the pallet.

[0044] When the pallet needs to pass, the cylinder 22 pulls the pull rod 21 to slide in the direction away from the lifting seat 4 until the angle between the connecting rod 1 71 and the connecting rod 2 72 is less than 180 degrees, blocking the seat 1 from descending, and the pallet passes through the pulley 13 of the second section 122 until it passes over the rocker arm 12. After the pallet passes through the rocker arm 12, the first section 121 automatically descends under the action of gravity, and then the second section 122 is tilted upward.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
