Description

Technical Field

[0001] The utility model relates to the field of machining, in particular to an integrated transmission device for loading and unloading materials. Background Art

[0002] In the resistor production line, the obtained products are transferred. This process generally uses a conveyor belt to transport the products over long distances. In the product transportation process, the products need to be transferred between adjacent workstations, which involves loading and unloading of products.

[0003] In scenarios where products need to be driven back and forth between two workstations, two parallel conveyor belts can be used, one for loading and the other for unloading. However, this method can only be used in scenarios with sufficient space. When the space is small, the conveyor belt needs to have a reversing function, and the motor can be driven by operating the switch to rotate forward and reverse on the same conveyor belt to achieve loading and unloading actions. In this method, the forward and reverse rotation of the motor increases the operating burden of the motor, and the motor failure rate will increase when used in situations where frequent loading and unloading is required.

[0004] Therefore, how to make a single conveyor belt have the functions of loading and unloading materials, and not increase the burden on the motor during frequent switching, so as to ensure the smooth operation of the equipment, is a problem that needs to be solved. Utility Model Content

[0036] The utility model provides a loading and unloading integrated transmission device 10, which comprises: a transmission belt body 100, a forward rotation component 200, a reverse gear disc 300 and a switch 400.

[0037] See also Figure 1 and Figure 2 The conveyor body 100 includes a motor 110, a carrier belt 120, a frame 130, and a tensioning wheel 140 and two driven wheels 150 located on the frame 130. The two driven wheels 150 are respectively located at both ends of the frame 130. The tensioning wheel 140 and the two driven wheels 150 stretch the carrier belt 120 so that the carrier belt 120 is kept in a tensioned state for carrying products.

[0038] See also Figure 4 and Figure 5 The switch 400 includes a fixed roller 410 and a magnetic rod 420. The fixed roller 410 is connected to the output end of the motor 110. The fixed roller 410 is a hollow structure. Two working areas 41 are provided on the fixed roller 410. Each working area 41 is provided with a through hole 411. The through hole 411 is connected to the inner cavity of the fixed roller 410 (such as Figure 7 As shown), a stopper steel ball 42 is provided in the through hole 411, a magnetic rod 420 passes through the fixed roller 410, and two annular grooves 421 are provided on the outer wall of the magnetic rod 420 (as shown Figure 8 As shown), the distance between the two annular grooves 421 is smaller than the distance between the two working areas 41.

[0039] The magnetic rod 420 is made of a magnet and can absorb the stop steel ball 42. The outer diameter of the magnetic rod 420 matches the inner diameter of the fixed roller 410. When an external force is applied, the magnetic rod 420 can slide along the inner cavity of the fixed roller 410, thereby making the annular groove 421 approach or move away from the working area 41. Specifically, when the annular groove 421 moves to the working area 41, the annular groove 421 is aligned with the through hole 411, and the stop steel ball 42 in the through hole 411 is sunk into the annular groove 421 under the influence of the magnetic force; when the annular groove 421 is offset from the working area 41, the outer wall of the magnetic rod 420 pushes the stop steel ball 42 into the through hole 411, and partially exposes the stop steel ball 42 on the outside of the fixed roller 410. Preferably, there are multiple through holes 411 in each working area 41, and each through hole 411 contains a stop steel ball 42.

[0040] See also Figure 5 and Figure 6 It should be emphasized that, since two annular grooves 421 are provided on the outer wall of the magnetic rod 420, the distance between the two annular grooves 421 is smaller than the distance between the two working areas 41, and the distances between the two are inconsistent. Therefore, when one of the annular grooves 421 is aligned with the working area 41, the other annular groove 421 must be staggered with the other working area 41.

[0041] See also Figure 3 and Figure 4 The forward rotation component 200 includes a pulley 210 and a synchronous belt 220. The pulley 210 is rotatably disposed on one of the working areas 41. The synchronous belt 220 connects the pulley 210 and the tensioning wheel 140. When the pulley 210 rotates, the synchronous belt 220 is used to pull the tensioning wheel 140 to rotate synchronously.

[0042] When the annular groove 421 on the magnetic rod 420 is offset from the working area 41 on the side where the pulley 210 is located, the stop steel ball 42 is squeezed toward the pulley 210, thereby locking the pulley 210 and the fixed roller 410. In this state, the pulley 210 and the fixed roller 410 rotate synchronously, and the tensioning wheel 140 is driven to rotate through the synchronous belt 220, so that the carrier belt 120 runs forward to load the material. Figure 6 On the contrary, when the annular groove 421 on the magnetic rod 420 is aligned with the working area 41 on the side where the pulley 210 is located, the stop steel ball 42 is retracted, and the pulley 210 and the fixed roller 410 are in a rotatable state. At this time, the fixed roller 410 cannot drive the pulley 210 to rotate. Figure 5 shown.

[0043] See also Figure 3 and Figure 4 The counter toothed disc 300 is rotatably disposed on another working area 41, and the end of the tension wheel 140 is provided with an outer tooth 141 that meshes with the counter toothed disc 300. When the counter toothed disc 300 rotates, the tension wheel 140 is driven to rotate by the outer tooth 141, and the rotation directions of the tension wheel 140 and the counter toothed disc 300 are opposite (gear transmission principle).

[0044] When the annular groove 421 on the magnetic rod 420 is offset from the working area 41 on the side where the reverse gear disc 300 is located (such as Figure 5 As shown in FIG. 4 ), the stopper steel ball 42 is pressed toward the reverse gear disc 300, thereby locking the reverse gear disc 300 and the fixed roller 410. In this state, the reverse gear disc 300 and the fixed roller 410 rotate synchronously, and the reverse gear disc 300 meshes with the outer teeth 141 on the tension wheel 140. Therefore, the reverse gear disc 300 drives the tension wheel 140 to reverse, so that the carrier belt 120 runs forward to unload the material. On the contrary, when the annular groove 421 on the magnetic rod 420 is aligned with the working area 41 on the side where the reverse gear disc 300 is located (as shown in FIG. 4 ), the reverse gear disc 300 and the fixed roller 410 rotate synchronously. The reverse gear disc 300 is engaged with the outer teeth 141 on the tension wheel 140. Therefore, the reverse gear disc 300 drives the tension wheel 140 to reverse, thereby allowing the carrier belt 120 to run forward to unload the material. Figure 6As shown), the stop steel ball 42 is retracted, and the reverse gear plate 300 and the fixed roller 410 are in a rotatable state. At this time, the fixed roller 410 cannot drive the reverse gear plate 300 to rotate.

[0045] It should be emphasized again that when the direction of material transmission of the integrated loading and unloading transmission device 10 needs to be switched, it is only necessary to hold the magnetic rod 420 and apply a pulling force (or a pushing force) to the magnetic rod 420 to make it slide along the axial direction of the fixed roller 410. Since two annular grooves 421 are provided on the outer wall of the magnetic rod 420, the distance between the two annular grooves 421 is smaller than the distance between the two working areas 41, and the distances between the two are inconsistent. That is, only one of the pulley 210 and the reverse gear disc 300 can be locked with the fixed roller 410.

[0046] Specifically, after applying a pulling force to pull the magnetic rod 420 outward, the annular groove 421 is offset from the working area 41 on the side where the pulley 210 is located, and the stop steel ball 42 is squeezed toward the pulley 210, locking the pulley 210 and the fixed roller 410, and the annular groove 421 is aligned with the working area 41 on the side where the reverse gear plate 300 is located, and the reverse gear plate 300 and the fixed roller 410 are not locked. At this time, the pulley 210 rotates with the fixed roller 410, and the reverse gear plate 300 is in a driven state, such as Figure 6 As shown;

[0047] On the contrary, after the thrust magnetic rod 420 is pushed inward, the annular groove 421 is offset from the working area 41 on the side where the reverse gear disc 300 is located, and the stop steel ball 42 is squeezed toward the reverse gear disc 300, locking the reverse gear disc 300 and the fixed roller 410, and the annular groove 421 is aligned with the working area 41 on the side where the pulley 210 is located, and the pulley 210 and the fixed roller 410 are not locked. At this time, the reverse gear disc 300 rotates with the fixed roller 410, and the pulley 210 is in a driven state, such as Figure 5 shown.

[0048] Preferably, see Figure 5 , bushings 520 are provided at the positions of the reverse gear disc 300 and the pulley 210 that contact the outer wall of the fixed roller 410. The bushings 520 make the positions of the reverse gear disc 300 and the pulley 210 that contact the outer wall of the fixed roller 410 more wear-resistant. Resin washers 510 are provided at the positions of the reverse gear disc 300 and the pulley 210 that contact the working area 41. In this way, when the annular groove 421 is offset from the working area 41, the stop steel ball 42 squeezes the resin washer 510, causing the resin washer 510 to expand and then hold the reverse gear disc 300 (or the pulley 210).

[0049] In one embodiment, please refer to Figure 5The fixed roller 410 is provided with a first limiting portion 412 and a second limiting portion 413, the reverse toothed disc 300 is fitted with the first limiting portion 412, and the pulley 210 is fitted with the second limiting portion 413. The first limiting portion 412 and the second limiting portion 413 provide positioning for the reverse toothed disc 300 and the pulley 210 to prevent them from deflecting.

[0050] In one embodiment, please refer to Figure 1 The conveyor body 100 further includes a pitch-adjusting rod 160, which passes through one of the driven wheels 150, and a waist-shaped hole 131 matching the pitch-adjusting rod 160 is provided on the frame 130. The pitch-adjusting rod 160 can be dragged to move along the waist-shaped hole 131, thereby adjusting the tension of the carrier belt 120.

[0051] Preferably, the diameter of the counter toothed disc 300 is consistent with the diameter of the tension wheel 140. This ensures that the loading and unloading speeds of the integrated loading and unloading transmission device 10 are consistent.

[0052] In one embodiment, please refer to Figure 8 The magnetic rod 420 is provided with a handle 422. The outer wall of the handle 422 is provided with anti-slip grooves. A reversing mark is attached to the outer wall of the handle 422, and the reversing mark is used to inform the user of the transmission direction of the loading and unloading integrated transmission device 10.

[0053] The novel disclosed integrated loading and unloading transmission device 10 has the following advantages:

[0054] 1. The switch 400 triggers the forward rotation assembly 200 or the reverse rotation gear disc 300 to change the transmission direction of the carrier belt 120, so that the transmission device can both load and unload materials, saving space;

[0055] 2. When changing the transmission direction, there is no need to change the rotation direction of the output end of the motor 110, which reduces the burden on the motor 110 and ensures stable operation of the equipment.

[0056] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
