Description

Technical Field

[0001] This utility model relates to the field of automatic feeding devices, specifically to a tongue depressor for automatic feeding and an automatic feeding device. Background Technology

[0002] Because manual packaging is involved in the pharmaceutical production process, the packaging boxes need to be printed in three stages after manual packaging.

[0003] Existing packaging boxes are often transported via long tracks. However, in actual use, it has been found that when box-shaped workpieces are pushed by push rods, the unstable force of the push rods can cause one end of the packaging box to shift, which can easily lead to jamming problems during high-speed operation. At the same time, when the tilted packaging boxes enter the conveyor belt, they are prone to slipping or tilting, which affects the product's entry into the next process, increases energy consumption and worker workload, and affects product production efficiency.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem of material jamming caused by one end of a box-shaped workpiece shifting during high-speed conveying in the prior art, this utility model provides a pressure tongue device for automatic feeding. The pressure tongue device for automatic feeding includes: a stepped shaft having a first abutment surface and a second abutment surface; a pressure tongue including a lug sleeved on the stepped shaft and an arc-shaped pressure plate connected to the lug; the lug abuts against the first abutment surface and the second abutment surface; a pressure adjusting structure including a mounting cylinder arranged on the stepped shaft and a spring sleeved on the stepped shaft; one end of the spring is connected to the pressure tongue, and the other end is connected to the mounting cylinder.

[0006] This utility model relates to a pressure tongue device for automatic feeding, comprising a stepped shaft, a pressure tongue, and a pressure adjustment structure. The stepped shaft mounts the pressure tongue device above a conveyor track. The pressure tongue includes a lug and an arc-shaped pressure plate. The two ends of the lug abut against a first and a second contact surface, respectively, effectively limiting the rotation of the pressure tongue on the stepped shaft. The arc-shaped pressure plate is connected to the lug and presses a box-shaped workpiece against the conveyor track. If the box-shaped workpiece is skewed, the skewed end will first abut against the arc-shaped pressure plate and remain there under its resistance, thus correcting the skewed workpiece. The pressure adjustment structure includes a mounting cylinder and a spring. One end of the spring is connected to the mounting cylinder, and the other end is connected to the pressure tongue, increasing the clamping force of the pressure tongue. With the above settings, the tongue-pressing device for automatic feeding of this utility model can press the box-shaped workpiece against the conveyor track. If the box-shaped workpiece is skewed, the skewed end will first come into contact with the arc-shaped pressure plate and stop under the resistance of the arc-shaped pressure plate, thereby correcting the skewed box-shaped workpiece and preventing the conveyor track from jamming.

[0007] Furthermore, a weight-reducing groove is provided on the arc-shaped pressure plate.

[0008] Furthermore, the mounting cylinder is rotatably sleeved on the stepped shaft, and a fixing bolt that abuts against the stepped shaft is provided on the mounting cylinder.

[0009] Furthermore, a limiting member is detachably arranged at one end of the stepped shaft, and the second abutment surface is formed on the limiting member.

[0010] Furthermore, an external thread is formed on the stepped shaft, and the limiting member is threadedly connected to the stepped shaft.

[0011] Furthermore, it also includes a fastener, on which a through hole matching the stepped shaft and a threaded hole matching the through hole are provided, and a locking bolt is arranged in the threaded hole.

[0012] To improve or solve the technical problem in the prior art where box-shaped workpieces tend to shift at one end during high-speed conveying, easily causing jamming, this utility model provides an automatic feeding device. The automatic feeding device includes a feeding track; a conveying track connected to the feeding track; and the aforementioned pressure tongue device for automatic feeding, the pressure tongue device being installed on the feeding track.

[0013] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0014] The arc-shaped pressure plate is connected to the lugs, which press the box-shaped workpiece against the conveyor track. If the box-shaped workpiece is skewed, the skewed end will first come into contact with the arc-shaped pressure plate and stop under the resistance of the pressure plate, thus correcting the skewed box-shaped workpiece. The pressure adjustment structure includes a mounting cylinder and a spring. One end of the spring is connected to the mounting cylinder, and the other end is connected to the pressure tongue, which can increase the clamping force of the pressure tongue.

Figure 1 and Figure 2As shown, in one or more embodiments, the tongue presser device for automatic feeding of this utility model includes a stepped shaft 1, a tongue presser 2, and a pressure adjustment structure 3.

[0024] See also Figure 1 and Figure 2 In one or more embodiments, one end of the stepped shaft 1 is fixed to the feeding track 200 by a fastener 11. Specifically, the fastener 11 is generally rectangular in shape and is fixed to the feeding track 200 by welding. The fastener 11 has a through hole that mates with the stepped shaft 1 and a threaded hole that mates with the through hole. The stepped shaft 1 is inserted into the through hole, and a locking bolt 12 is provided in the threaded hole.

Further, the stepped shaft 1 has a first abutment surface and a second abutment surface for limiting the pressure tongue 2. Specifically, the stepped shaft 1 extends from the fastener 11 in a direction perpendicular to the material conveying direction. The diameter of the stepped shaft 1 decreases along its length, forming a step, and the first abutment surface is formed on the step. For example, the stepped shaft 1 has a first step length of 50 mm and a diameter of 6 mm; the second step has a length of 50 mm and a diameter of 5 mm. Further, a limiting member 13 is provided at the end of the stepped shaft 1 away from the fixing member 11, and a second abutment surface is formed on the side of the limiting member 13 near the fixing member 11.

An external thread is formed on the stepped shaft 1, and a threaded hole matching the external thread is provided on the limiting member 13, thereby facilitating the insertion and removal of the pressure tongue 2 from the stepped shaft 1.

[0025] See also Figure 1 and Figure 2 In one or more embodiments, the pressure tongue 2 is rotatably mounted on the stepped shaft 1. The pressure tongue 2 includes a lug 21 sleeved on the stepped shaft 1 and an arc-shaped pressure plate 22 connected to the lug 21. Specifically, there are two lugs 21, which are arranged opposite to each other and abut against the first and second abutment surfaces respectively, thereby mounting the pressure tongue 2 on the stepped shaft 1. The arc-shaped pressure plate 22 is generally rectangular and bent into a certain arc, so that its side view is generally arc-shaped. One side of the arc-shaped pressure plate 22 is fixedly connected to the lug 21, and the opposite side faces the conveyor track 300. Further, a weight-reducing groove 23 is provided on the arc-shaped pressure plate 22 to reduce the weight of the arc-shaped pressure plate 22. The arc-shaped pressure plate 22 with the weight-reducing groove 23 is generally frame-shaped. For example, the arc-shaped pressure plate 22 is a rectangular plate with a length of 70 mm, a width of 30 mm, and a wall thickness of 5 mm. The diameter of the loop 21 is 5.5mm.

[0026] See also Figure 1 and Figure 2In one or more embodiments, the pressure regulating structure 3 includes a mounting cylinder 31 arranged on the stepped shaft 1 and a spring 32 sleeved on the stepped shaft 1. Specifically, the mounting cylinder 31 is sleeved at one end near the limiting member 13. A threaded hole is formed in the mounting cylinder 31 radially, and a fixing bolt 33 is provided in the threaded hole. The fixing bolt 33 abuts against the stepped shaft 1, thereby fixing the mounting cylinder 31 to the stepped shaft 1. The spring 32 is sleeved on the stepped shaft 1, with one end connected to the pressure tongue 2 and the other end connected to the mounting cylinder 31. Exemplarily, the spring 32 applies a pressure of approximately 5N.

[0027] To improve or solve the technical problem in the prior art where box-shaped workpieces tend to shift at one end during high-speed conveying, easily causing jamming, this utility model provides an automatic feeding device. The automatic feeding device includes a feeding track 200; a conveying track 300 connected to the feeding track 200; and the aforementioned pressure tongue device for automatic feeding, which is installed on the feeding track 200.

[0028] See also Figure 1 and Figure 2 The unloading track 200 includes four corner plates arranged side by side, forming a roughly rectangular space. Box-shaped workpieces are arranged between the four corner plates. A conveying track 300 is arranged below the unloading track 200, and a push rod is provided at one end of the unloading track 200. Based on... Figure 1 As shown, the push rod is mounted on the left and pushes the box-shaped workpiece to the right. The tongue depressor is mounted on the unloading track 200 and is located above the conveying track 300. For example, the fixing member 11 of the tongue depressor is approximately 50 mm away from the conveying track 300 in the vertical direction.
