Sampling hooks 7 are provided on both the front and rear sides of the outer side of the sleeve 6. The front and rear sampling hooks 7 are arranged flush with each other, and the openings of the sampling hooks 7 face the clockwise side of the rotating sleeve 6. That is to say, when the rotating sleeve 6 rotates clockwise, the sampling hooks 7 continuously hook up the protective tube 47 on the left side of the raw material storage tank 1, so that the protective tube 47 continuously moves to the right side, and a material guide plate 8 inclined toward the lower right is provided on both the front and rear sides of the upper end of the right side wall of the raw material storage tank 1. A rotating seat 9 is provided at the right end of the material guide plate 8, and the rotating seat 9 is rotatably connected to the left end of the deflection plate 10;

[0028] The grinding mechanism 4 includes a hanging frame 32 arranged on the side of the product storage tank 2 away from the raw material storage tank 1. The hanging frame 32 is an L-shaped structure. The vertical plate of the hanging frame 32 is fixed to the right side wall of the product storage tank 2. The horizontal plate of the hanging frame 32 is arranged just above the product storage tank 2. The lower end of the vertically arranged baffle 33 is fixedly connected to the left end of the horizontal plate of the hanging frame 32. When the deflection plate 10 is in the initial state, the baffle 33 is just located at the right end of the deflection plate 10.

The front and rear ends of the horizontal platform 34 are slidably connected with a vertically arranged pressure rod 35. The lower end of the pressure rod 35 is provided with an arc-shaped pressure head 36. A groove structure matching with the protective tube 47 is provided below the arc-shaped pressure head 36, and an anti-slip rubber pad is provided on the inner wall of the groove structure.

The side of the ball head grinding head 23 close to the product storage groove 2 is hemispherical, that is, when the protective tube 47 moves downward in the front-to-back direction, the front and rear ends of the protective tube 47 will first contact the arc surface of the ball head grinding head 23, so that the protective tube 47 will move forward and backward to achieve the centering effect, and a spring is arranged inside the sliding sleeve 22, so that the sliding sleeve 22 can move slightly back and forth, so that when the protective tube 47 moves downward, the ball head grinding head 23 will slide adaptively, so that the protective tube 47 can pass through the ball head grinding head 23 and move downward.

[0029] In one case of this embodiment, a first drive motor 14 is provided on the outside of the raw material storage tank 1, and the output shaft of the first drive motor 14 is fixedly connected to the first bevel gear 13, and the first bevel gear 13 is meshedly connected to the second bevel gear 12, and the angle of each rotation of the rotating sleeve 6 is the same as the central angle of the circle corresponding to two adjacent sampling hooks 7. That is, the first drive motor 14 makes the rotating sleeve 6 rotate intermittently through gear transmission, so that the sampling hook 7 intermittently transfers the protective tubes 47 to the guide plate 8 one by one, and the rotating sleeve 6 can also continue to rotate at a slower speed, and the protective tubes 47 are also transferred to the guide plate 8 one by one, and it is only necessary to ensure that the gap arc pressure head 36 of the feeding of the protective tube 47 can grind the protective tube 47.

[0030] In one case of this embodiment, when the deflection plate 10 is unloaded, the end of the deflection plate 10 close to the product storage slot 2 deflects toward the ground, and the guide plate 8 is provided with an angle reset component 11 for driving the deflection plate 10 to maintain the tilted state. The deflection plate 10 is slightly tilted to the lower right in the initial state, that is, after the protective tube 47 moves onto the deflection plate 10, the protective tube 47 will continue to roll to the right end along the deflection plate 10. The angle reset component 11 includes a vertically arranged guide slide bar 15 fixedly connected to the guide plate 8, a sliding plate 17 is slidably connected to the middle part of the guide slide bar 15, the sliding plate 17 is rotatably connected to one end of the support rod 16, and the other end of the support rod 16 is rotatably connected to the deflection plate 10, and a limit plate 19 is provided at the end of the guide slide bar 15, and a reset spring 18 is provided between the limit plate 19 and the sliding plate 17.

[0031] In one case of this embodiment, a synchronous rotation drive assembly 31 for driving the two ball-end grinding heads 23 to rotate synchronously is provided at the bottom of the product storage tank 2. The synchronous rotation drive assembly 31 includes a transmission shaft 28 rotatably connected to the bottom of the product storage tank 2, a driving pulley 27 is provided at the end of the transmission shaft 28, the driving pulley 27 is connected to the driven pulley 24 through a synchronous belt 25, and the driven pulley 24 is fixedly connected to the end of the main shaft 20, and a second drive motor 30 is provided on the outer side of the product storage tank 2, and the output shaft of the second drive motor 30 is fixedly connected to the third bevel gear 29, and the third bevel gear 29 is meshedly connected to the fourth bevel gear 26 fixedly connected to the transmission shaft 28.

[0032] In one case of the present embodiment, a reciprocating lifting drive assembly 37 for driving the pressure rod 35 to rise and fall is provided in the middle of the horizontal platform 34. The reciprocating lifting drive assembly 37 includes a pressure plate 46 fixedly connected to the end of the pressure rod 35 away from the product storage slot 2, a lifting spring 44 is provided between the pressure plate 46 and the horizontal platform 34, a side plate 38 is provided in the middle of the horizontal platform 34, the upper end of the side plate 38 is rotatably connected to the second rotating shaft 41, the end of the second rotating shaft 41 close to the pressure plate 46 is fixedly connected to one end of the rotating plate 43, and the other end of the rotating plate 43 is fixedly connected to the lever 45 matched with the pressure plate 46, and a third driving motor 39 is provided in the middle of the side plate 38, the output shaft of the third driving motor 39 is fixedly connected to the fifth bevel gear 40, and the fifth bevel gear 40 is meshingly connected to the sixth bevel gear 42 fixedly connected to the end of the second rotating shaft 41.

[0033] During the implementation of this embodiment, the raw material storage tank 1 is placed at the discharge port of the protective tube 47 extruder, so that the protective tube 47 can fall on the left side of the raw material storage tank 1 in a front-to-back direction, or can be directly placed on the ground, and the protective tube 47 is transported to the left side of the raw material storage tank 1 in a front-to-back direction by a manual or assembly line conveyor belt, and by setting the positions of the front and rear sampling hooks 7, the distance between the rear sampling hook 7 and the front side wall of the raw material storage tank 1 and the distance between the front sampling hook 7 and the rear side wall of the raw material storage tank 1 are smaller than the length of the protective tube 47, so that after the protective tube 47 falls into the raw material storage tank 1, one protective tube 47 will always be in synchronous contact with the two sampling hooks 7, and the protective tube 47 can be lifted up when the sampling hook 7 rotates, and the product storage tank 2 is placed on the right side of the raw material storage tank 1, so that the baffle 33 is just located at the right end of the deflection plate 10, and the entire device can work normally at this time.

[0034] The first drive motor 14, the second drive motor 30 and the third drive motor 39 are started. The first drive motor 14 drives the rotating sleeve 6 to rotate clockwise intermittently through gear transmission, so that the sampling hook 7 can lift the protective tube 47 inside the raw material storage tank 1 when it is on the left side. At this time, the sampling hook 7 continues to rotate. When the protective tube 47 moves to the upper side, as shown in the attached figure, Figure 2 At this time, the protective tube 47 will fall on the left side of the sampling hook 7 on the right side. As the rotating sleeve 6 continues to rotate, the protective tube 47 will fall on the material guide plate 8, and finally roll onto the deflection plate 10 and be blocked by the baffle 33. The second drive motor 30 always drives the two ball head grinding heads 23 to continuously rotate.

[0035] The third driving motor 39 drives the arc pressure head 36 to move up and down. The arc pressure head 36 moves downward first, and the groove below the arc pressure head 36 will fall on the top of the protective tube 47. At this time, the protective tube 47 will be pressed downward by the arc pressure head 36, and the deflection plate 10 will rotate clockwise. When the protective tube 47 is disengaged from the deflection plate 10, the deflection plate 10 rotates to the initial state. At this time, the front and rear ends of the protective tube 47 will contact the top of the ball head grinding head 23. At this time, if the protective tube 47 is not in the center position, the protective tube 47 will slide along the arc surface of the ball head grinding head 23, so that the front and rear ends of the protective tube 47 are in contact with the ball head grinding head 23, realizing the automatic centering of the protective tube 47, and as the protective tube 47 continues to descend, the front and rear protective tubes 47 are adaptively separated from each other, and in the process of the protective tube 47 contacting the rotating ball head grinding head 23, due to the rubber pad set inside the arc pressure head 36, The protective tube 47 will not rotate. At this time, the ball-head grinding head 23 will grind the front and rear ends of the protective tube 47. When the protective tube 47 moves to the bottom of the ball-head grinding head 23, the protective tube 47 is disengaged from the ball-head grinding head 23. At this time, the protective tube 47 falls into the product storage tank 2, and the arc pressure head 36 moves upward again. During the grinding process, the second protective tube 47 rolls on the deflection plate 10 and presses on the pressure rod 35. When the pressure rod 35 moves upward with the arc pressure head 36, the second protective tube 47 will be pushed to the left. When the arc pressure head 36 moves to the top, the protective tube 47 will roll again to stick to the baffle 33, waiting for the arc pressure head 36 to fall again for grinding. By setting the working gap, the first drive motor 14 drives the protective tube 47 to sample and the third drive motor 39 drives the protective tube 47 to grind, which can be carried out alternately, thereby realizing continuous grinding of the protective tube 47.

[0036] The present invention is applicable to a plastic protective tube end grinder for automobile radars. The single-piece sampling process of the protective tube 47 is realized by rotating the sampling hook 7, and the protective tube 47 is driven by the arc-shaped pressure head 36 to contact with two ball-head grinding heads 23 to realize the grinding process of the two ends at the same time, so that the present grinder can effectively grind the protective tube 47. The structure and control of the whole grinder are relatively simple, so that the processing difficulty and the use difficulty of the grinder are relatively low, and the grinder is suitable for popularization and use.

[0037] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
