Description

Technical Field

[0001] This utility model relates to the field of automatic air feeder technology, specifically a bidirectional feeding mechanism and a compact air feeder. Background Technology

[0002] In the processing industries of hardware, electronics, plastics and other parts, in order to improve the efficiency of punching, automatic air feeders are usually used. The working principle of the automatic air feeder is mainly driven by a pneumatic system. It uses the direction and magnitude of compressed air intake and exhaust to drive the feeding, clamping and transmission mechanisms, so as to achieve the purpose of precise, high-speed and safe feeding of punching.

[0003] Existing air feeders consist of a main body, guide columns, and a rear seat forming the overall framework. The main body includes feeding, clamping, control, and transmission mechanisms. They employ a cylinder and piston assembly structure, using the direction and magnitude of compressed gas intake and exhaust to move the clamping plates via the cylinder, piston, and piston rod, thus achieving the feeding operation. A baffle wheel and guide roller are provided at one end of the inlet to assist with feeding. However, in existing air feeders, the baffle wheel and guide roller are usually fixed at one end. This causes material deviation when the air feeder needs to feed in the opposite direction, as the other end lacks a baffle wheel and guide roller, affecting feeding efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a bidirectional feeding mechanism and a compact air feeder to solve the problem mentioned in the background art, where the baffle wheel and guide roller of the existing air feeder are usually fixed at one end, so that when the air feeder needs to feed in the opposite direction, the material will deviate at the other end due to the lack of baffle wheel and guide roller, which affects the feeding efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a bidirectional feeding mechanism, including a connecting frame and a guide portion:

[0006] The connecting frame has a connecting rod a at one end and a connecting rod b at the other end. A guide part is located at one end of the connecting frame and has a support frame inside the guide part. One end of the support frame has a locking hole that engages with connecting rod a and connecting rod b. Connecting rod a is inserted into the locking hole to connect the guide part to the end of the connecting frame near connecting rod a, and connecting rod b is inserted into the locking hole to connect the guide part to the end of the connecting frame near connecting rod b.

[0007] By adopting the above technical solution and changing the setting position of the support frame, the guide can be installed at both ends of the feeder, so that when the device feeds in the forward or reverse direction, the guide can limit the material at its inlet to prevent it from deviating during conveying, thereby improving the feeding efficiency.

[0008] Preferably, the guide portion further includes a stop wheel rotatably disposed on the top of the support frame and a guide roller rotatably disposed at one end of the support frame, the stop wheel being slidably connected to the top of the support frame.

[0009] By adopting the above technical solution, the gap between the two guide rollers can be slidably set, allowing the feeder to perform a feeding operation on materials of different widths.

[0010] Preferably, the guide portion also has a groove formed inside the support frame, in which a carriage is slidably disposed.

[0011] By adopting the above technical solution, the carriage can slide and displace inside the support frame.

[0012] Preferably, the guide portion also has two plugs disposed at one end of the carriage, and the two plugs are slidably connected to the support frame. Each of the two plugs is nested with a spring, which is located between the support frame and the plug.

[0013] By adopting the above technical solution, the spring can push the bolt to slide inside the support frame.

[0014] Preferably, the connecting frame also has limiting holes a on both sides of the connecting rod a, and there are two limiting holes a, which are engaged with two plugs.

[0015] By adopting the above technical solution, the bolt can be inserted into the limiting hole a, thereby restricting the position of the support frame.

[0016] Preferably, the connecting frame also has limiting holes b on both sides of the connecting rod b, and there are two limiting holes b, which are engaged with two plugs.

[0017] By adopting the above technical solution, the bolt can be inserted into the limiting hole b, thereby restricting the position of the support frame.

[0018] Another aspect of this utility model provides a compact air feeder, including the bidirectional feeding mechanism described above, and the compact air feeder further includes a valve body:

[0019] The valve body is housed within a connecting frame. An air inlet is located on the side of the valve body, and a drive rod at the top controls the high-pressure gas input through the air inlet. A movable clamping plate is slidably mounted at one end of the valve body, and a fixed clamping plate is located at the top. The input of high-pressure gas through the air inlet drives the movable and fixed clamping plates to clamp materials.

[0020] By adopting the above technical solution, high-pressure gas can be introduced through the air inlet, and the moving clamp and fixed clamp can be used to clamp the moving material through the control of the transmission pressure rod.

[0021] Compared with the prior art, the beneficial effects of this utility model are: by providing a guide part, the guide part can be installed at both ends of the feeder by changing the setting position of the support frame, so that when the device feeds in the forward or reverse direction, the guide part can limit the material at its inlet to prevent it from deviating during conveying, thereby improving the feeding efficiency.

A locking hole 204 is provided at one end of the support frame 201. The locking hole 204 engages with the connecting rod a101 and the connecting rod b103. The connecting rod a101 is inserted into the locking hole 204 so that the guide part 2 is connected to the end of the connecting frame 1 near the connecting rod a101. The connecting rod b103 is inserted into the locking hole 204 so that the guide part 2 is connected to the end of the connecting frame 1 near the connecting rod b103. By engaging the locking hole 204 at one end of the support frame 201 with the connecting rod a101 or the connecting rod b103, the guide part 2 can be installed at both ends of the feeder, thereby improving the feeding efficiency.

[0032] Example 2

[0033] Please see Figure 3 , Figure 4 and Figure 5 This embodiment provides a technical solution: a bidirectional feeding mechanism, including a guide 2, a support frame 201, and a slide 205.

[0034] A sliding groove is provided inside the support frame 201, and a slide carriage 205 is slidably disposed within the groove, allowing the slide carriage 205 to slide within the support frame 201. Two bolts 206 are provided at one end of the slide carriage 205, and both bolts 206 are slidably connected to the support frame 201. Each bolt 206 is nested with a spring 207, which is located between the support frame 201 and the bolt 206, allowing the spring 207 to push the bolt 206 to slide within the support frame 201. (The last sentence appears to be incomplete and possibly refers to a connecting rod a.) Limiting holes a102 are provided on both sides of 101. There are two limiting holes a102. The two limiting holes a102 are engaged with two plugs 206, allowing the plugs 206 to be inserted into the limiting holes a102, thereby restricting the position of the support frame 201. Limiting holes b104 are provided on both sides of the connecting rod b103. There are two limiting holes b104. The two limiting holes b104 are engaged with two plugs 206, allowing the plugs 206 to be inserted into the limiting holes b104, thereby restricting the position of the support frame 201.

[0035] Example 3

[0036] Please see Figure 1 , Figure 2 and Figure 3 This embodiment also provides a technical solution: a compact air feeder, including a valve body 3:

[0037] The valve body 3 is installed inside the connecting frame 1. An air inlet 301 is provided on the side of the valve body 3. A transmission pressure rod 302 is provided at the top of the valve body 3. The transmission pressure rod 302 controls the high-pressure gas input into the air inlet 301. A movable clamping plate 303 is slidably provided at one end of the valve body 3. A fixed clamping plate 304 is provided at the top of the valve body 3. High-pressure gas is input into the air inlet 301 to drive the movable clamping plate 303 and the fixed clamping plate 304 to clamp the material. High-pressure gas can be input through the air inlet 301. Through the control of the transmission pressure rod 302, the movable clamping plate 303 and the fixed clamping plate 304 can clamp the moving material.

[0038] Working principle: First, before using the feeder, an external air pump must be connected to the air inlet 301. High-pressure gas is input through the air inlet 301. Controlled by the transmission pressure rod 302, the moving clamp 303 and the fixed clamp 304 clamp the moving material. During the material conveying process, the guide part 2 can be installed at both ends of the feeder by engaging with the connecting clamp rod a101 or connecting clamp rod b103 through the locking hole 204 at one end of the support frame 201, thereby improving the feeding efficiency. Specifically, rotate the entire guide part 2 vertically 90° to engage the locking hole. Insert 204 into the connecting rod a101 or connecting rod b103, then rotate it 90° in the opposite direction so that the connecting rod a101 or connecting rod b103 engages with the locking hole 204. During the engagement process, the slide 205 needs to be pulled away from the end of the connecting rod a101 or connecting rod b103. When the entire guide part 2 is in a horizontal state, release the slide 205, so that the bolt 206 can be locked into the limiting hole a102 or limiting hole b104 under the action of the spring 207, thereby restricting the position of the support frame 201.
