Description

Technical Field

[0001] This utility model relates to the field of logistics, and in particular to a roller mill blocking mechanism. Background Technology

[0002] When roller conveyors transport materials, they often require a blocking mechanism to limit and position the material during transport, ensuring that the material stops accurately at a predetermined position. Patent application CN201621461494.4 discloses a roller conveyor blocking device, which uses a cylinder to raise and lower a baffle to block the material. Existing blocking mechanisms largely utilize this structure. However, this roller conveyor blocking device has the following drawbacks: 1) Because there is often a gap between the rollers on the roller conveyor, the blocking device cannot fine-tune the position of the baffle located between the two rollers, thus affecting the accuracy of the material blocking position; 2) The guide frame is fixed to the machine frame, making installation, disassembly, or repositioning very cumbersome and requiring significant manpower and resources. Therefore, there is an urgent need for a roller conveyor blocking mechanism that allows for fine-tuning of the baffle position and is easy to install. Utility Model Content

Detailed Implementation

[0022] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] This utility model provides a technical solution: a roller mill blocking mechanism, including two horizontal bars 1, connected by several connecting bars 2, with a set of elongated holes 3 on each horizontal bar 1, and a cross brace 4 detachably connected to each horizontal bar 1. A fixed seat 5 is fixed between the two horizontal braces 4, and a reduction motor 6 is fixed on the fixed seat 5. A crank 7 is fixed on the output shaft of the reduction motor 6, and a first bearing 8 is fixed on the crank 7. The first bearing 8 is disposed in a rectangular groove 9, which is formed on a blocking plate 10. A limiting structure 11 is provided on the blocking plate 10. This utility model is used in conjunction with a double-chain roller mill. The blocking mechanism is installed below the double-chain roller mill, and the specific location below the double-chain roller mill is determined according to the actual material blocking position required. During operation, simply place the blocking mechanism at the desired position below the double-chain roller mill and fix it in place. At this time, the blocking plate 10 is aligned with the gap between the two rollers above it, and the blocking plate 10 is in a low position. Then, the reduction motor 6 starts and drives the crank 7 to rotate, thereby raising the blocking plate 10 so that it passes through the gap between the two rollers above it until it is higher than the rollers. Since the gap between the two rollers has a certain width, the position of the blocking plate 10 between the two rollers can be finely adjusted through the elongated hole 3 according to the requirements of the material blocking position. The crossbar 1 and cross brace 4 are locked together by fasteners that pass through the elongated slot 3. For fine-tuning, simply loosen all fasteners and slowly move the cross brace 4, thereby moving the blocking plate 10 until it reaches the desired position. After moving the blocking plate 10 to the desired position, tighten the previously loosened fasteners again, thus locking and fixing the crossbar 1 and cross brace 4. This completes the fine-tuning of the blocking plate 10, which is not only convenient but also greatly improves the accuracy of material blocking. After fine-tuning the blocking plate 10, it can block the material being conveyed on the double-chain roller conveyor. When it is necessary to change the material's position on the double-chain roller conveyor, simply lower the blocking plate 10 to its lowest position using the reduction motor 6, and then move the entire blocking mechanism to the desired position. This is very convenient. This invention sets the limiting structure 11 on the blocking plate 10 instead of on the double-chain roller conveyor, thus eliminating installation steps and greatly improving installation efficiency.

[0024] There are two sets of elongated holes 3, which are respectively located at the left and right ends near the crossbar 1. A pad 12 is provided above the elongated hole 3. The pad 12 is fixed to the crossbar 4. The end of the pad 12 extends beyond the end of the crossbar 4. A cylindrical head screw 13 passes through the part of the pad 12 that extends beyond the crossbar 4. The cylindrical head screw 13 passes through the elongated hole 3. A washer 14 is fitted on the cylindrical head screw 13 located below the elongated hole 3. The cylindrical head screw 13 locks the pad 12 to the crossbar 1 through the first nut 15. The cylindrical head screw 13, washer 14, and first nut 15 act as fasteners, locking and loosening the crossbar 1 and cross brace 4. When fine-tuning the blocking plate 10 is required, first loosen all the first nuts 15 (not completely unscrew them), then slowly move the cross brace 4. During the movement of the cross brace 4, the cylindrical head screw 13 moves within the elongated hole 3, which provides sufficient clearance for its movement. The movement of the cross brace 4 moves the blocking plate 10 until it reaches the desired position. Then, tighten the first nuts 15 one by one. This completes the fine-tuning of the blocking plate 10, which is very convenient and quick. The shim 12 greatly facilitates the fixing and disassembly of the crossbar 1 and cross brace 4. Furthermore, the shim 12 reduces the length of the cylindrical head screw 13, saving material.

[0025] A support block 16 is fixed to the left end of the crossbar 1, and a bolt 17 passes through the support block 16. The right end of the bolt 17 is fixed to the left end face of the cross brace 4. A second nut 18 is provided on each of the bolts 17 on both sides of the support block 16. The bolts 17 further enhance the fixing effect between the crossbar 1 and the cross brace 4, and also limit the left and right directions of the cross brace 4 during fine-tuning, which not only facilitates fine-tuning but also ensures the accuracy of fine-tuning. During fine-tuning, the two second nuts 18 need to be loosened. After fine-tuning, the two second nuts 18 can be tightened back towards the support block 16.

[0026] The limiting structure 11 includes an L-shaped plate 19 fixed to the cross brace 4. A stiffening rib 20 is fixed to the L-shaped plate 19. A first nylon plate 21 is fixed to the right side of the L-shaped plate 19 near its inner end. The right side of the first nylon plate 21 contacts the left side of the blocking plate 10. The right side of the blocking plate 10 contacts the left side of a second nylon plate 22, which is fixed to a support plate 23. The support plate 23 is fixed to the L-shaped plate 19. Through the setting of the limiting structure 11, the front and rear ends of the blocking plate 10 are limited between the first nylon plate 21 and the second nylon plate 22, which not only provides a good limiting effect but also provides good protection for the surface of the blocking plate 10. The L-shaped plate 19 and the stiffening rib 20 significantly improve the support effect of the blocking plate 10.

[0027] Several screws 24 are fixed through the support plate 23 and the L-shaped plate 19 at the same end, and spacers 25 are provided on the screws 24 between the support plate 23 and the L-shaped plate 19. By fixing the L-shaped plate 19 and the support plate 23 in this way, not only is the fixing effect of the two increased, but the space between the first nylon plate 21 and the second nylon plate 22 will not easily change, thereby ensuring the limiting effect on the blocking plate 10.

[0028] Several connecting shafts 26 are fixedly fixed through the L-shaped plate 19. The connecting shafts 26 and the screws 24 are spaced apart. A second bearing 27 is fixed to the right end of the connecting shaft 26, and the second bearing 27 contacts the end face of its corresponding blocking plate 10. This arrangement provides good guidance for the blocking plate 10 during its lifting and lowering process.

[0029] Vertical supports 28 are fixed to both ends of the horizontal support 1. A base plate 29 is fixed to the vertical support 28, and adjustable feet 30 are provided on the base plate 29. The vertical supports 28 allow the reduction motor 6 to be further away from the ground, thus providing some protection for the reduction motor 6. The base plate 29 and the adjustable feet 30 effectively adjust the height of the entire roller mill blocking mechanism.

[0030] Working Principle: This invention is used in conjunction with a double-chain roller mill. The blocking mechanism is installed below the double-chain roller mill, with the specific location determined by the material blocking position required. During operation, the blocking mechanism is placed and fixed at the desired position below the double-chain roller mill. At this point, the blocking plate 10 is aligned with the gap between the two rollers above it, and is in its low position. Then, the reduction motor 6 starts, driving the crank 7 to rotate, raising the blocking plate 10 until it passes through the gap between the two rollers above it and is higher than the rollers. Since the gap between the two rollers has a certain width, the position of the blocking plate 10 between the two rollers is fine-tuned through the elongated hole 3 according to the material blocking position requirements. When fine-tuning the baffle plate 10 is required, first loosen all the first nuts 15 (not completely unscrewed). Then, slowly move the cross brace 4. During the movement of the cross brace 4, the cylindrical head screw 13 moves within the elongated hole 3. The elongated hole 3 provides sufficient clearance for the movement of the cylindrical head screw 13. The movement of the cross brace 4 moves the baffle plate 10 until it reaches the desired position. Then, tighten the first nuts 15 one by one. This completes the fine-tuning of the baffle plate 10, which is not only convenient but also greatly improves the accuracy of the material blocking position. After fine-tuning the baffle plate 10, it can be used to block the material being conveyed on the double-chain roller conveyor. When it is necessary to change the positioning of the material on the double-chain roller conveyor, simply lower the baffle plate 10 to the low position using the reduction motor 6, and then move the entire blocking mechanism to the desired position. This is very convenient. This utility model sets the limiting structure 11 on the blocking plate 10 instead of on the double-chain roller machine, which saves the installation steps and greatly improves the installation efficiency.
