[0035] The clamping type loading device according to the first embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] like Figures 1 to 4 As shown, the clamping type feeding device according to an embodiment of the present invention includes a clamping mechanism 30 for clamping materials, a box body and a transmission mechanism 40.

[0037] Specifically, the clamping mechanism 30 includes an upper clamping plate 31 and a lower clamping plate 32 connected to the upper clamping plate 31. The first end of the upper clamping plate 31 is connected to the first end of the lower clamping plate 32. The second end of the upper clamping plate 31 is provided with a first opening angle relative to the second end of the lower clamping plate 32. The side wall of the box body is provided with an opening. The clamping mechanism 30 is movably arranged outside the opening of the box body. The transmission mechanism 40 is fixed to the box body and connected to the clamping mechanism 30. The transmission mechanism 40 drives the clamping mechanism 30 to move toward the inside of the opening and forms a second opening angle between the upper clamping plate 31 and the lower clamping plate 32 through the two side walls of the opening. The second opening angle is smaller than the first opening angle. The material can be a plate, film, or other object that can be clamped.

[0038] The clamping feeding device of the present invention is described in detail below by taking the clamping of EVA film as an example. Specifically, the clamping mechanism 30 is arranged on the outside of the box body, and the transmission mechanism 40 is arranged on the inside of the box body. When the film is loaded, the upper clamping plate 31 and the lower clamping plate 32 of the clamping mechanism 30 on the outside of the box body are opened at a first opening angle, so that the film can be placed between the upper clamping plate 31 and the lower clamping plate 32. The transmission mechanism 40 on the inside of the box body is connected to the clamping mechanism 30 on the outside and the box body opening. When the transmission mechanism 40 rotates, it drives the clamping mechanism 30 to move to the inside of the box body opening. When the upper clamping plate 31 and the lower clamping plate 32 of the clamping structure pass through the box body opening, the upper clamping plate 31 and the lower clamping plate 32 of the clamping mechanism 30 are squeezed together by the upper and lower walls of the box body opening, so that a second opening angle is opened between the upper clamping plate 31 and the lower clamping plate 32 of the clamping mechanism 30, wherein the second opening angle is smaller than the first opening angle, thereby clamping the EVA film.

[0039] like Figure 3 As shown, the clamping mechanism 30 also includes a support spring 33 and a connecting pin 34. A first mounting hole is provided on the first end of the upper clamping plate 31, and a second mounting hole is provided on the first end of the lower clamping plate 32. The connecting pin 34 passes through the first mounting hole, the support spring 33 and the second mounting hole to connect the first end of the upper clamping plate 31 and the first end of the lower clamping plate 32.

[0040] That is to say, the clamping mechanism 30 is provided with a support spring 33 and a connecting pin 34. The center hole of the support spring 33 is arranged side by side with the first mounting hole of the upper clamping plate 31 and the second mounting hole of the lower clamping plate 32. The connecting pin 34 passes through the first mounting hole, the center hole of the support spring 33 and the second mounting hole to connect the first end of the upper clamping plate 31 and the first end of the lower clamping plate 32. At the same time, the support spring 33 provides elastic compensation force for the upper clamping plate 31 and the lower clamping plate 32, thereby forming an angle between the upper clamping plate 31 and the lower clamping plate 32, namely the first opening angle and the second opening angle. When the EVA film is loaded, the upper clamping plate 31 and the lower clamping plate 32 of the clamping mechanism 30 are opened to clamp the EVA film.

[0041] According to one embodiment of the present invention, the box body includes a lower box body 20 and an upper cover 10, wherein the side wall of the lower box body 20 is provided with a groove, and the upper cover 10 is provided with a protrusion. The upper cover 10 is detachably arranged on the lower box body 20, and when the upper cover 10 is sealed on the lower box body 20, the protrusion is embedded in the groove, and an opening is formed between the protrusion and the groove.

[0042] That is to say, if Figure 1As shown, the upper cover 10 is sealed on the upper end of the lower box body 20, and the protrusion of the upper cover 10 is just embedded in the groove of the lower box body 20. In addition, there is an opening between the protrusion of the upper cover 10 and the groove of the lower box body 20. The clamping mechanism 30 is connected to the transmission mechanism 40 at the opening. When the transmission mechanism 40 drives the clamping mechanism 30 to move toward the inner side of the box body opening, the upper clamping plate 31 of the clamping mechanism 30 is squeezed by the protrusion of the upper cover 10, and the lower clamping plate 32 is squeezed by the groove wall of the lower box body 20, and then the upper clamping plate 31 and the lower clamping plate 32 are closed together to clamp the EVA film.

[0043] According to one embodiment of the present invention, Figure 4 As shown, the transmission mechanism 40 includes a rotating connecting rod 41 and a push rod 42. The rotating connecting rod 41 is rotatably arranged in the box body. The rotating connecting rod 41 is fixedly connected to the clamping mechanism 30. The push rod 42 is fixedly connected or detachably connected to the rotating connecting rod 41. For example, a screw or nut fixing structure can be used for connection, or a pin can be used for connection, which is not limited here. By installing the transmission mechanism 40 inside the box body, wherein the rotating connecting rod 41 is connected to the clamping mechanism 30 outside the box body, when the push rod pulls the rotating connecting rod forward or backward, the rotating connecting rod rotates and pulls the clamping mechanism backward, even if the clamping mechanism moves in the direction of the rotating connecting rod, it is convenient to pull the clamping mechanism. This structure is simple and easy for users to operate.

[0044] Specifically, a first connecting portion 411 is provided on the outer periphery of the rotating link 41, and a slot is provided on the push rod 42, into which the first connecting portion 411 engages. In other words, the slot of the push rod 42 engages with the first connecting portion 411 of the rotating link 41. When the push rod 42 is pulled, the rotating link 41 rotates, which in turn drives the clamping mechanism 30 to move toward the inside of the box opening, thereby clamping the EVA film.

[0045] According to another embodiment of the present invention, the rotating link 41 includes a second connecting portion 412, which is provided with a fixing hole for passing the connecting pin 34. The clamping mechanism 30 is hingedly connected to the second connecting portion 412 via the connecting pin 34 and the fixing hole. In other words, the second connecting portion 412 of the rotating link 41 is provided with a fixing hole, and the connecting pin 34 is connected to the upper clamping plate 31, the lower clamping plate 32, and the support spring 33 of the clamping mechanism 30 through the fixing hole, thereby achieving a movable connection between the upper clamping plate 31 and the lower clamping plate 32 relative to the fixing hole.

[0046] Optionally, the box body is provided with multiple openings and clamping mechanisms 30 corresponding to the openings, that is, the box body is provided with at least one opening, and a clamping device is installed at each opening. For example, when a push rod is connected to multiple rotating connecting rods, each rotating connecting rod is connected to a clamping mechanism, it can be achieved by one person operating the push rod that multiple clamping mechanisms can be moved and opened or closed at the same time to clamp items. It can also be achieved by a rotating connecting rod being connected to multiple clamping mechanisms to drive multiple clamping mechanisms to clamp items at one time, thereby ensuring that the loading process is smoother and the wide-width EVA film is clamped more powerfully.

[0047] Optionally, a fixed shaft 21 and a bearing 43 are provided on the lower box body 20 . The fixed shaft 21 is fixedly connected to the upper cover 10 by bolts. The bearing 43 is nested in the outer periphery of the fixed shaft 21 , and the outer periphery of the bearing 43 is connected to the rotating connecting rod 41 .

[0048] That is to say, a fixed shaft 21 is provided inside the lower box body 20, and a bolt hole 11 is provided in the upper cover 10. The upper cover 10 is fixedly connected to the fixed shaft 21 by bolts, and the bearing 43 is nested between the fixed shaft 21 and the rotating connecting rod 41. Therefore, when the rotating connecting rod 41 rotates, the friction is reduced, ensuring that the loading process is smoother.

[0049] In a preferred embodiment of the present invention, a push rod placement groove 29 is further provided on the lower box body 20 , the push rod 42 is longer than the push rod placement groove 29 , and one end of the push rod 42 extends outward from the lower box body 20 .

[0050] In other words, one end of the push rod 42 extends out of the box. During the loading process, simply push the push rod 42 to clamp the EVA film and load it. Once the EVA film is in place, release the push rod 42 to load the EVA film to the desired location. This simple and convenient loading process can be completed by a single person, improving efficiency. Furthermore, the tooling has a simple structure, making it easy to produce and manufacture.

[0051] The clamping type loading machine according to the second embodiment of the present invention includes the clamping type loading device of the above embodiment.

[0052] Since the clamp-type loading device according to the above embodiment of the present invention has the above technical effects, the clamp-type loading machine according to the embodiment of the present invention also has corresponding technical effects, that is, a single person can complete the loading operation, the process is simple and convenient, and the efficiency of the personnel is improved.

[0053] Other structures and operations of the clamping loader according to the embodiment of the present invention are understandable and easy to implement for those skilled in the art, and therefore will not be described in detail.

[0054] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
