Description

Technical Field

[0001] The utility model relates to the field of machining, in particular to a waste collection device. Background Art

[0002] like Figure 1 The spring processing machine 20 shown includes a discharge turntable 21 and a plurality of claw arms 22 arranged around the discharge turntable 21. The discharge turntable 21 is located at a discharge point of the wire. While the discharge turntable 21 is discharging the wire, each claw arm 22 extends out in turn to guide the wire to deform. After the spring is formed, a cutting operation is performed to separate the formed spring from the wire, and the processed spring falls directly into a recovery device.

[0003] In the process of pulling the wire from the discharging turntable 21, the spring processing machine 20 applies a pulling force to the wire, so that the wire is in a tensioned state. When the spring processing machine 20 stops, the tension on the wire will cause its end to retract into the discharging turntable 21, and the retracted length is uncertain. In order to ensure the production accuracy of the spring, when the machine is turned on, a small section of wire needs to be pulled out, and after being cut by the claw arm 22, the end of the wire is flush with the discharging turntable 21 before the spring production begins, and the cut part falls as waste; on the other hand, when the wire is exhausted, some of the wire will remain in the spring processing machine 20. Before replacing the new wire, the residual wire in the spring processing machine 20 needs to be discharged. In the existing spring processing machine 20, the waste discharge position and the spring drop position are at the same position, so it is necessary to arrange personnel to sort the waste mixed in the spring, which reduces the production efficiency of the spring.

[0004] Therefore, how to avoid mixing waste materials with qualified products is a problem that needs to be solved. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art and provide a waste collection device, which can separate waste from qualified products during the spring production process and improve the production efficiency of the spring.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] A waste material collection device, comprising: a housing, a material frame, a support platform and a material blocking module;

[0008] A material inlet is provided on a side of the shell close to the spring processing machine, a waste material outlet is provided in the inner cavity of the shell, the support platform is arranged in the shell, and a avoidance portion is provided on a side of the support platform close to the waste material outlet;

[0009] The material frame is placed on the top of the support platform;

[0010] The material blocking module includes a first rotating shaft, a second rotating shaft, a belt transmission assembly and a material blocking belt. The first rotating shaft and the second rotating shaft are both arranged in the shell, and the first rotating shaft and the second rotating shaft are both transmission connected to the belt transmission assembly. The material blocking belt is provided with a blocking section and a hollow section. The end of the blocking section is wound around the first rotating shaft, and the end of the hollow section is wound around the second rotating shaft. The belt transmission assembly drives the first rotating shaft and the second rotating shaft to rotate synchronously, so as to make the hollow section or the blocking section cover above the material inlet.

[0011] In one of the embodiments, a scratch-resistant rubber sleeve is provided on the edge of the material blocking belt.

[0012] In one of the embodiments, a plurality of avoidance grooves are provided on the outer wall of the anti-scratch rubber sleeve.

[0013] In one of the embodiments, an arc-shaped transition portion is provided at the connection between the hollow section and the blocking section.

[0014] In one embodiment, the belt transmission assembly includes a motor, a driving wheel, a synchronous belt and two driven wheels, wherein the first rotating shaft and the second rotating shaft are each provided with a driven wheel, the driving wheel is arranged at the output end of the motor, and the synchronous belt is used to drive the driven wheel to rotate synchronously with the driving wheel.

[0015] In one of the embodiments, the support platform is located at the center of the shell, and the diameter of the support platform decreases from the side close to the inner wall of the shell toward the position in contact with the material frame.

[0016] In one of the embodiments, a movable door is provided on the housing.

[0017] In one of the embodiments, an auxiliary support block is provided on the inner wall of the shell.

[0018] In one of the embodiments, it also includes an insert plate, which is slidably disposed at the waste discharge outlet.

[0019] In one of the embodiments, a hopper is provided on the housing, the hopper extends toward a side close to the spring processing machine, and an opening of the hopper is communicated with a feed inlet.

[0020] The above waste collection device has the following advantages:

[0021] 1. When the equipment is turned on and the wire is exhausted, the belt transmission component starts to pull out the blocking section of the blocking belt. After the waste enters the feed inlet, it is blocked by the blocking section to prevent it from falling into the feed frame, which can effectively prevent the waste from mixing with qualified products;

[0022] 2. When the equipment is operating normally, the belt transmission assembly reverses to pull out the hollow section so that the blocking belt no longer blocks the feed port. The finished spring can pass through the hollow section and fall into the material frame. Preliminary sorting can be performed during the spring processing to avoid mixing of waste materials and finished products, which is beneficial to improving the processing efficiency of the spring.

[0035] See also Figure 2 The utility model provides a waste collection device 10, which includes: a housing 100, a material frame 200, a support platform 300 and a material blocking module. The waste collection device 10 is arranged at the discharge position of the spring processing machine 20, and is used to collect waste generated during the processing. The material frame 200 is used to receive the processed springs, and the material blocking module is used to separate the waste generated during the processing from the springs to prevent the waste from entering the material frame 200.

[0036] See also Figure 2 and Figure 3 The housing 100 is provided with a feed inlet 110 on one side close to the spring processing machine, a waste outlet 120 is provided in the inner cavity of the housing 100, a support platform 300 is provided in the housing 100, and a side of the support platform 300 close to the waste outlet 120 is provided with an avoidance portion 310. The feed inlet 110 faces the location of the spring processing machine 20 (such as Figure 1 As shown in FIG. 1 , the waste and springs generated after the spring processing machine 20 is started all enter the inner cavity of the housing 100 from the feed port 110 .

[0037] Preferably, see Figure 3 and Figure 4 The waste collection device 10 further includes a plug plate 500, which is slidably disposed at the waste discharge port 120. The waste discharge port 120 is located at the bottom of the housing 100, and the plug plate 500 seals the waste discharge port 120 to make it in a normally closed state. The maintenance personnel regularly pull out the plug plate 500 to sweep the waste toward the waste discharge port 120, so that the waste is concentrated at the waste discharge port 120 and discharged, and the waste inside the housing 100 can be quickly cleaned.

[0038] Among them, see Figure 2 and Figure 4The material frame 200 is placed on the top of the support platform 300 , the material frame 200 is suspended inside the housing 100 , and the material frame 200 is located within the falling track of the spring, and is used to receive the spring processed by the spring processing machine 20 .

[0039] See also Figure 3 and Figure 4 The material blocking module includes a first rotating shaft 410, a second rotating shaft 420, a belt transmission assembly 430 and a material blocking belt 440. The first rotating shaft 410 and the second rotating shaft 420 are both arranged in the housing 100, and the first rotating shaft 410 and the second rotating shaft 420 are both connected to the belt transmission assembly 430. The material blocking belt 440 is provided with a blocking section 441 and a hollow section 442. The end of the blocking section 441 is wound around the first rotating shaft 410, and the end of the hollow section 442 is wound around the second rotating shaft 420. The belt transmission assembly 430 drives the first rotating shaft 410 and the second rotating shaft 420 to rotate synchronously, so as to make the hollow section 442 or the blocking section 441 cover the top of the feed port 110. Preferably, an arc-shaped transition portion 444 is provided at the connection between the hollow section 442 and the blocking section 441, which can avoid tearing at the junction of the hollow section 442 and the blocking section 441, so that the material blocking belt 440 is more durable.

[0040] It should be emphasized that the springs processed by the spring processing machine 20 and the waste generated during the processing are discharged at the same location, and the reasons for the waste are as follows:

[0041] 1. After the equipment is shut down, the wire will be slightly displaced due to its own stress and external tension. Therefore, in order to reduce the processing error, a small section of the wire needs to be pulled and cut off when the machine is started, so that the end of the wire is kept flush with the discharge turntable 21. Therefore, waste will be generated when the machine is started;

[0042] 2. When the wire is exhausted, some of the wire will remain in the spring processing machine 20. Before replacing the wire, this part of the wire needs to be discharged. Similarly, this part of the discharged wire also becomes waste and falls into the housing 100.

[0043] Therefore, the two nodes before the equipment is turned on and when the wire is replaced are the operation time of the material blocking module. The principle of preventing waste from entering the material frame 200 is as follows:

[0044] See also Figure 4 In the figure, the second rotating shaft 420 is located below the first rotating shaft 410. When the material blocking module is running, the belt transmission component 430 drives the first rotating shaft 410 and the second rotating shaft 420 to rotate synchronously, so that the first rotating shaft 410 unwinds the material blocking belt 440, and the second rotating shaft 420 rewinds the material blocking belt 440. In this process, the hollow section 442 on the material blocking belt 440 is gradually rewound onto the second rotating shaft 420 (such as Figure 7As shown), the blocking section 441 moves toward the side where the second rotating shaft 420 is located, and the blocking section 441 partially blocks the feed inlet 110, as shown Figure 5 As shown, the upper side of the feed inlet 110 is blocked, and the blocking section 441 is above the material frame 200. The waste material falls onto the blocking section 441, slides down along the blocking section 441, and enters the housing 100 at the lower side of the feed inlet 110.

[0045] After the spring processing machine 20 is turned on, the belt transmission assembly 430 drives the first rotating shaft 410 and the second rotating shaft 420 to rotate in opposite directions. At this time, the first rotating shaft 410 reels the blocking belt 440, while the second rotating shaft 420 unwinds the blocking belt 440, that is, the blocking belt 440 moves toward the side where the first rotating shaft 410 is located. In this process, the blocking section 441 is reeled onto the first rotating shaft 410 (such as Figure 6 As shown), the hollow section 442 moves toward the first rotating shaft 410, so that the feed port 110 is completely exposed. At this time, the state of the blocking belt 440 is as shown in FIG. Figure 3 As shown, at this time, the spring can fall into the material frame 200 along a normal falling trajectory.

[0046] Preferably, see Figure 8 A scratch-resistant rubber sleeve 443 is provided on the edge of the material blocking belt 440, and a plurality of avoidance grooves 41 are provided on the outer wall of the scratch-resistant rubber sleeve 443. The scratch-resistant rubber sleeve 443 increases the rigidity of the edge of the material blocking belt 440, so that the material blocking belt 440 is not easily scratched. The avoidance grooves 41 are added so that the scratch-resistant rubber sleeve 443 is not easily wrinkled during the unwinding and winding processes.

[0047] In one embodiment, please refer to Figure 5 and Figure 6 The belt transmission assembly 430 includes a motor 431, a driving wheel 432, a synchronous belt 433 and two driven wheels 434. A driven wheel 434 is provided on each of the first rotating shaft 410 and the second rotating shaft 420. The driving wheel 432 is provided at the output end of the motor 431. The synchronous belt 433 is used to drive the driven wheel 434 to rotate synchronously with the driving wheel 432. The motor 431 provides power, and the driving wheel 432, the driven wheel 434 and the synchronous belt 433 cooperate to allow the first rotating shaft 410 and the second rotating shaft 420 to rotate synchronously in the same direction, so that the belt transmission assembly 430 can operate smoothly.

[0048] In one embodiment, please refer to Figure 3 The support platform 300 is located at the center of the housing 100, and the diameter of the support platform 300 decreases from the side close to the inner wall of the housing 100 to the position in contact with the material frame 200. That is, the support platform 300 is cone-shaped, and the waste falls on the support platform 300 and slides down along its outer wall, ensuring that the waste is located at the bottom of the housing 100, which is convenient for later cleaning.

[0049] In one embodiment, please refer to Figure 3, a movable door 130 is provided on the housing 100. When the material frame 200 is filled with springs, the movable door 130 can be opened to facilitate the replacement of the material frame 200. Further, an auxiliary support block 140 is provided on the inner wall of the housing 100. The auxiliary support block 140 cooperates with the support platform 300 to support the material frame 200 to prevent the material frame 200 from tipping over.

[0050] In one embodiment, please refer to Figure 4 and Figure 5 The housing 100 has a hopper 150, which extends toward a side close to the spring processing machine, and an opening of the hopper 150 is connected to the feed inlet 110. The height of the hopper 150 is lower than the setting height of the material frame 200, and when the waste material slides down along the material blocking belt 440, it enters the feed inlet 110 from the position where the hopper 150 is located. The hopper 150 extends outward to prevent the waste material from falling outside the housing 100 when it bounces up.

[0051] The above waste collection device 10 has the following advantages:

[0052] 1. When the equipment is turned on and the wire is exhausted, the belt transmission component 430 starts to pull out the blocking section 441 of the blocking belt 440. After the waste enters the feed inlet 110, it is blocked by the blocking section 441 to prevent it from falling into the material frame 200, which can effectively prevent the waste from mixing with qualified products;

[0053] 2. When the equipment is operating normally, the belt transmission assembly 430 is reversed to pull out the hollow section 442, so that the blocking belt 440 no longer blocks the feed inlet 110, and the finished springs can pass through the hollow section 442 and fall into the material frame 200. Preliminary sorting can be performed during the spring processing to avoid mixing of waste materials and finished products, which is beneficial to improving the processing efficiency of the springs.

[0054] 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.
