Description

Technical Field

[0001] The utility model relates to the technical field of mud brick processing equipment, in particular to a board loading machine. Background Art

[0002] Mud bricks are one of the most basic building materials in the current construction industry, and their demand is huge. In modern mud brick manufacturing factories, mud bricks are usually pressed and molded by a brick press, and then stacked into square brick piles by trucks. During the pressing process, a loading machine is usually used to send the brick support plate and mud raw materials into the brick press for pressing. The demoulding mud bricks remain on the brick support plate and are sent out together with the brick support plate.

[0003] Existing loading machines usually use a motor-driven chain group as the main power system to drive the pulley on the frame to slide back and forth in a straight line to realize the conveying and movement of the brick support plate; however, due to space limitations in some factories and other reasons, the conveying direction of some brick support plates needs to be changed during the conveying process, so the corresponding loading machine's conveying track also needs to have a bend. The current loading machine is usually equipped with two conveying tracks in different directions and a reciprocating pulley is set on each conveying track to realize the direction change of the brick support plate. The pulley on one conveying track will transport the brick support plate to another conveying track, and then the pulley on the other conveying track will realize the conveyance of the brick support plate, thereby realizing the direction change of the brick support plate.

[0004] In order to ensure that the brick support plate can be smoothly transferred between the two pulleys, the two pulleys need to move synchronously to avoid interference or delay between the two pulleys during the transportation of the brick support plate. Existing equipment usually uses two motors to control two sets of chain groups respectively to drive the two pulleys, but the structure of this drive system is relatively complex. For conveyor tracks of different lengths, the chain needs to be specially customized. If the chain needs to be replaced after damage, it takes a long time to wait, which wastes time and is costly.

[0027] The following will be combined with 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 of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of the utility model.

[0028] Embodiment 1

[0029] like Figure 1-8 As shown, this embodiment discloses a plate loading machine, comprising a first frame 1 with a conveying track 3 and a second frame 2, wherein a discharge end 5 of the first frame 1 is connected to a feed end 4 of the second frame 2 and the two are arranged at an angle, as shown in FIG. Figure 1 As shown, the first frame 1 and the second frame 2 both include a support frame 10 for supporting a pallet, the conveying track 3 is arranged below the support frame 10, the first pulley 6 and the second pulley 7 are slidably arranged on the conveying track 3, the first pulley 6 and the second pulley 7 both include a bracket 11 slidably arranged on the conveying track 3 through rollers, the bracket 11 slides below the support frame 10, and a push plate spring key 12 is arranged at the rear end of the bracket 11 along the material conveying direction, as shown in FIG. Figure 8As shown, the push plate spring key 12 is rotatably arranged on the bracket 11 and a coil spring is arranged between the push plate spring key 12 and the bracket 11 so that the push plate spring key 12 can swing upward to achieve reset. The first trolley 6 is provided with a material storage bin at the feeding end 4 of the first frame 1, and the material storage bin is arranged above the supporting frame 10. The brick supporting plates can be stacked and placed in the material storage bin, and the brick supporting plate at the bottom of the material storage bin is placed on the supporting frame 10; each time the first pulley 6 is reset to the feeding end 4 of the first frame 1, the push plate spring key 12 will move to the rear of the material storage bin, and the rear end surface of the push plate spring key 12 is arranged in an inclined shape, and the front end surface is a vertical surface. When the push plate spring key 12 is reset, after its rear end surface abuts against the brick supporting plate, the push plate spring key 12 will swing downward to allow the pulley to continue to reset; and when the push plate spring key 12 is away from the supporting plate brick, it will swing upward under the action of the coil spring. At this time, the front end surface of the push plate spring key 12 will be arranged opposite to the supporting plate brick. At this time, when the first pulley 6 moves forward, after the front end surface of the push plate spring key 12 abuts against the brick supporting plate, it will push the brick supporting plate at the bottom of the material storage bin to move forward, thereby realizing the transportation of the brick supporting plate.

[0030] like Figure 1-3 As shown, a driving mechanism for driving the first pulley 6 and the second pulley 7 is provided on the first frame 1 and the second frame 2, and the driving mechanism includes a push rod assembly 9 provided on the second frame 2, and the push rod assembly 9 includes a driving seat 91 fixedly provided on the second frame 2, and a control push rod 92 reciprocating along the conveying direction of the supporting brick plate is slidably provided on the driving seat 91, and one end of the control push rod 92 is connected to the second pulley 7; and the other end is connected to the first pulley 6 through the traction rope assembly 8. The front end of the control push rod 92 of the push rod assembly 9 is connected to the second pulley 7, and can drive the second pulley 7 to slide reciprocatingly along the conveying track 3 of the second frame 2; the driving seat 91 can be a standard cylinder, and the output shafts at the front and rear ends thereof are both connected to the control push rod 92, and the control push rod 92 at the front end is connected to the second traction rope, and the control push rod at the rear end is connected to the first traction rope.

[0031] The traction rope assembly 8 includes a first traction rope 81 connecting the first pulley 6 and the second pulley 7, and a second traction rope 82 connecting the first pulley 6 and the control push rod 92; and also includes a pulley A83 for tensioning the first traction rope 81 and a pulley block B84 for tensioning the second traction rope 82. The pulley block B84 includes a transfer pulley 841 arranged on the first frame 1 and located at the rear end of the first pulley 6 along the material conveying direction, and a fixed pulley 842 arranged at the intersection of the first frame 1 and the second frame 2. One end of the second traction rope 82 is connected to the first pulley 6, and the other end is connected to the control push rod 92 at the rear end of the driving seat through the transfer pulley 841 and the fixed pulley 842 in sequence.

[0032] When the control push rod 92 pushes the second pulley 7 to move along the conveying track 3 of the second frame 2 toward its discharge end 5, the second pulley 7 will pull the first pulley 6 along the conveying track 3 of the first frame 1 toward its discharge end 5 through the first traction rope 81, thereby realizing the synchronous advancement of the brick supporting plate; and when the control push rod 92 retracts to control the second pulley 7 to retreat and reset, the control push rod 92 will also drive the first pulley 6 to retreat and reset through the second traction rope 82.

[0033] The cooperation between the traction rope and the push rod assembly 9 can realize the synchronous control between the first pulley 6 and the second pulley 7, and its structure is simpler. When the traction rope is broken or worn, the staff can directly disassemble and replace the traction rope, which is more convenient and has lower cost, making subsequent replacement and maintenance more convenient, reducing time cost and maintenance cost. The traction rope can be a steel wire rope.

[0034] Among them, pulley A83 and fixed pulley 842 can both be ordinary pulleys, and the first traction rope 81 and the second traction rope 82 only pass through pulley A83 and fixed pulley 842. The function of the pulley is only to maintain the tension and pulling direction of the first traction rope 81 and the second traction rope 82. Since pulley A83 and fixed pulley 842 are both ordinary pulleys, the movement speed of the first pulley 6 and the second pulley 7 will remain the same, and the moving distance will also be the same.

[0035] Embodiment 2

[0036] like Figure 5-6 As shown, the pulley A83 is arranged at the connection between the first frame 1 and the second frame 2, including a rotating shaft 831 rotatably arranged on the first frame 1, and a driving pulley 832 and a passive pulley 833 are fixedly arranged on the rotating shaft 831 to rotate coaxially; the first traction rope 81 is divided into a driving rope 811 and a passive rope 812, one end of the driving rope 811 is wound around the driving pulley 832, and the other end is connected to the second pulley 7, and one end of the passive rope 812 is wound around the passive pulley 833, and the other end is connected to the first pulley 6 Through the above structure, when the control push rod 92 drives the second pulley 7 forward, the second pulley 7 will pull the driving rope 811 to drive the rotating shaft 831 to rotate, and the rotation of the rotating shaft 831 will drive the passive pulley 833 to reel in the passive rope 812, thereby driving the first pulley 6 to move forward; and when the control push rod 92 moves backward, the second traction rope 82 will generate a backward pulling force on the first pulley 6 through the transfer pulley 841, thereby driving the second pulley 7 to reset backward, and the first pulley 6 will also slide backward to reset. At this time, when the first pulley 6 resets backward, the passive rope 812 will be pulled to drive the driving pulley 832 to rotate, thereby realizing the reeling of the driving rope 811.

[0037] The passive pulley 833 and the driving pulley 832 are distributed along the length direction of the rotating shaft 831 to form a tower pulley structure.

[0038] By making the pulley A83 have a passive pulley 833 and a driving pulley 832, and the two pulleys are arranged in a tower pulley structure distributed up and down, the staff can make the passive pulley 833 and the driving pulley 832 have different wheel diameters, for example Figure 6 The pulley A83 shown in the figure makes the wheel diameter of the passive pulley 833 larger than the wheel diameter of the driving pulley 832, so that when the second pulley 7 moves a certain distance, the driving rope 811 will be pulled outward to drive the driving pulley 832 and the passive pulley 833 to rotate. At this time, since the wheel diameter of the passive pulley 833 is larger, when the driving pulley 832 and the passive pulley 833 rotate synchronously, the passive pulley 833 has a longer winding length of the passive rope 812 of the first traction rope 81, so that the moving speed of the first pulley 6 is faster than that of the second pulley 7, which is suitable for the situation where the moving distance of the first pulley 6 is longer and the moving distance of the second pulley 7 is shorter. Similarly, if the moving distance of the first pulley 6 is shorter than that of the second pulley 7, the wheel diameter of the driving pulley 832 can be made larger than the wheel diameter of the passive pulley 833.

[0039] However, since the moving distances of the second pulley 7 and the first pulley 6 are different and the moving distance of the control push rod 92 is the same as the moving distance of the second pulley 7, if the second traction rope 82 connecting the control push rod 92 and the first pulley 6 is a complete one, then if the moving distance of the second pulley 7 (i.e., the moving distance of the control push rod 92) is greater than the moving distance of the first pulley 6, the distance that the control push rod 92 transports the second traction rope 82 forward will be greater than the distance that the first pulley 6 pulls the second traction rope 82 forward, which will cause the second traction rope 82 to loosen.

[0040] On the contrary, if the moving distance of the second pulley 7 (i.e., the moving distance of the control push rod 92) is smaller than the moving distance of the first pulley 6, then after both pulleys move forward, the distance that the control push rod 92 transports the second traction rope 82 forward will be smaller than the distance that the first pulley 6 pulls the second traction rope 82 forward, thereby causing the second traction rope 82 to be too tight.

[0041] Therefore, in order to ensure that the second traction rope 82 is not too tight or loose, the structure of the fixed pulley 842 is modified in this embodiment.

[0042] The fixed pulley 842 includes a connecting shaft 843 rotatably arranged on the first frame 1, and a driving wheel 844 and a driven wheel 845 that rotate coaxially are fixedly arranged on the connecting shaft 843. The second traction rope 82 is divided into a driving rope 821 and a driven rope 822. One end of the driving rope 821 is connected and wound around the driving wheel 844, and the other end is connected to the control push rod 92. One end of the driven rope 822 is wound around the driven wheel 845, and the other end is connected to the first pulley 6 through the transfer pulley 841.

[0043] Through the above structure, when the control push rod 92 drives the second pulley 7 to slide backward and reset, and generates a pulling force on the active rope 821, the active rope 821 will drive the active wheel 844 to rotate, so that the driven wheel 845 can rotate to reel in the driven rope 822, thereby realizing the reset and retreat of the first pulley 6; when the control push rod 92 moves forward and drives the second pulley 7 to move forward, the first pulley 6 will be pulled forward and moved. At this time, the driven rope 822 will be pulled outward and drive the driven wheel 845 to rotate. The rotation of the driven wheel 845 will drive the active wheel 844 to rotate to realize the reeling of the active rope 821, thereby avoiding the loosening of the wiring harness between the control push rod 92 and the active wheel 844; and dividing the second traction rope 82 into two sections, the active rope 821 and the driven rope 822, can also avoid the second traction rope 82 being too tight.

[0044] Embodiment 3

[0045] Based on the second embodiment, Figure 7 As shown, the wheel core of the passive pulley 833 is conically arranged, and its wheel diameter gradually decreases along the axial direction of the rotating shaft 831. By making the wheel core of the passive pulley 833 conical, when the passive rope 812 is wound or released, the length of the passive rope 812 that is instantly released or wound is in a dynamically changing state, so that when the second pulley 7 moves, it can drive the first pulley to perform speed change movement to adapt to use in more working occasions.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
