In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or reference letters in the various examples, which have been repeated for purposes of simplicity and clarity and do not in themselves dictate a relationship between the various embodiments and/or arrangements discussed. In addition, the present disclosure provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.

For convenience of description, the transport belt (referred to as the first transport belt 1') is herein designated as being transported in the rear direction, i.e., to the left in fig. 2; the front is opposite the back, i.e. to the right in fig. 2.

Referring to fig. 1-2, the utility model provides a detection structure for feeding of a paper tube, including the mounting bracket 1 that sets up at the rear end of the conveyer belt (referring to the first conveyer belt 1' of the paper tube feeding device), the front side of the top of the mounting bracket is provided with an L-shaped swing plate 2, the swing plate is composed of a transverse plate 2.1 and a vertical plate 2.2, the rear side of the transverse plate 2.1 is pivotally connected with the mounting bracket 1, the front side of the transverse plate 2.1 is connected with the upper side of the vertical plate 2.2, the height difference between the lower side of the vertical plate 2.2 and the upper surface of the conveyer belt is smaller than the diameter of the paper tube 90 (to ensure that the paper tube 90 can strike the vertical plate 2.2); the top of the mounting frame 1 is also provided with a proximity sensor 3 opposite to the vertical plate 2.2 and a resetting component 4 for resetting the swinging plate.

See fig. 3, for a paper tube feeding device for conveying paper tubes of film rolls, the detection structure for paper tube feeding is arranged at the rear end of the first conveying belt 1 ', when in operation, when the paper tube 90 moves to the rear end along with the conveying belt (the first conveying belt 1 '), the paper tube 90 can impact the vertical plate 2.2 to swing the swinging plate 2, so that the vertical plate can trigger the proximity sensor 3 to form a control signal to start the material pushing mechanism 3 ' of the paper tube feeding device to push materials, at the moment, the paper tube 90 cannot move backwards continuously due to the blocking of the vertical plate 2.2, therefore, the conveying belt does not need to be suspended in the material pushing process, and the frequent switching of the conveying belt can be avoided.

Preferably, the length of the swing plate 2 is not less than the width of the conveyor belt (the first conveyor belt 1'), so as to ensure that the paper tube 90 can be blocked in the whole material pushing process.

Further, the mounting frame 1 comprises a mounting frame main body 1.1 and an L-shaped adjusting plate 1.2; adjusting plate 1.2 comprises horizontal plate 1.2a and riser 1.2b, offers the waist hole that extends along the fore-and-aft direction on the horizontal plate 1.2a and fixes at the mounting bracket main part 1.1 top (as shown in fig. 1) by the screw that passes the waist hole, proximity sensor 3 fixes on vertical plate 1.2b (as shown in fig. 2). The front and back position of the swing plate 2 can be adjusted by adjusting the front and back position of the adjusting plate 1.2 to meet the requirement of the triggering position of the paper tubes 90 with different lengths, and the proximity sensor 3 can move together with the adjusting plate 1.2, so that the relative position of the proximity sensor 3 and the vertical plate 2.2 is not changed along with the position change of the adjusting plate 1.2.

The return assembly 4 may be a compression spring connected between the riser portion 1.2b and the riser 2.2. As shown in fig. 1 and 2, the reset assembly 4 includes a weight rod 4.1 whose front end is fixedly connected to the transverse plate 2.1 and whose rear end is inclined upward, a weight 4.2 fixedly connected to the rear end of the weight rod, and a support member 4.3 for supporting the middle of the weight rod; the support 4.3 is arranged on the lateral plate part 1.2a of the adjusting plate; the gravity of the weight 4.2 will make the swing plate 2 swing upwards, and the position of the support 4.3 to the weight rod 4.1 will make the swing plate 2 keep the initial angle in the free state.

Preferably, the support 4.3 is adjustable in its fore-and-aft position. The position of the supporting point of the support 4.3 on the weight rod 4.1 is changed by adjusting the front and back positions of the support, so that the initial angle of the swing plate 2 can be adjusted, the initial distance between the proximity sensor 3 and the vertical plate 2.2 can be adjusted, and under the condition that the sensitivity of the proximity sensor 3 is unchanged, the sensitivity of the whole detection structure can be optimized by adjusting the initial angle of the swing plate 2 (because the impact force of paper tubes with the same size on the swing plate 2 is fixed, the initial angles of the swing plates 2 are different, the displacement which can be generated by the same impact force is different, and the larger the displacement is, the higher the sensitivity is).

In this embodiment, the supporting member 4.3 is an L-shaped plate, and the bottom thereof is provided with a waist hole extending forward and backward, and is fixedly connected with the adjusting plate 1.2 through a screw passing through the waist hole.

Further, referring to fig. 2, a limit screw 5 may be disposed on the vertical plate portion 1.2b of the adjustment plate, and a front end of the limit screw 5 is located in front of the proximity sensor 3, so as to prevent the swing plate 2 from colliding with the proximity sensor 3. Here, the position of the mounting bracket main body 1.1 facing the limit screw 5 is provided with a clearance hole 1.1a for the limit screw 5 to pass through, so as to adjust the position of the limit screw 5.

In some embodiments, the detecting structure for feeding paper tubes further includes a lifting mechanism for driving the mounting frame 1 to lift. In the actual use process, when the horizontal plate 2.1 of the swinging plate 2 is horizontal or the included angle between the horizontal plate and the horizontal plane is smaller, if the height of the upper end of the paper tube 90 is higher than the height of the front end of the swinging plate 2, the swinging plate 2 cannot swing or the swinging angle is very small during impact, so that the sensitivity is lower; here, through the height of elevating system regulation mounting bracket 1, can guarantee that fiber container 90 strikes the lower part at riser 2.2 all the time, can avoid this problem.

Specifically, the lifting mechanism comprises a fixed plate 6 fixedly connected with the conveyor belt rack, a lifting plate 7 arranged above the fixed plate, and a cylinder 8 which is upwards arranged at the bottom of the fixed plate 6 and used for driving the lifting plate 7 to move up and down; the mounting frame main body 1.1 is fixedly connected with the lifting plate 7.

Furthermore, two guide posts 9 are fixedly connected to the bottom of the lifting plate 7, corresponding guide sliding sleeves 10 are arranged on the fixing plate 6, and the guide posts 9 are slidably arranged in the corresponding guide sliding sleeves 10 in a penetrating manner.

In order to protect the paper tube 90 from being damaged, an elastic cushion layer 2.2a can be arranged on the front side surface of the vertical plate 2.2.

In the description herein, references to the description of the terms "one embodiment," "certain embodiments," "an illustrative embodiment," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention.
