DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and do not limit the scope of the present invention.

[0020] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The specific embodiments are as follows:

[0023] Embodiment 1, as Figure 1-4 As shown, a waste material reeling device for a blister forming machine comprises a support body 1 and a reel 4. The reel 4 is mounted on the support body 1 and is used to reel in the waste material after blister forming.

[0024] The support body 1 includes a support cross bar 11 and a support frame 12. Two support cross bars 11 are provided, which are parallel and spaced apart. The support frame 12 is used to fix the support cross bars 11. The support frame 12 includes vertical supports spaced apart and horizontal supports connected between the vertical supports, and a horizontal support is connected between the vertical supports respectively connected to the lower sides of the two support cross bars 11 to ensure the stability of the support frame 12.

[0025] A rotating seat 2 is provided near both ends of the upper side of the supporting crossbar 11, and a reel 4 is mounted on the rotating seat 2. The reel 4 is rotated to realize the winding of the waste. The reel 4 for winding the waste is mounted on the rotating seat 2 near the blister machine. After the reel 4 is fully wound, the full reel 4 is moved to the rotating seat 2 far away from the blister machine, and then the empty reel 4 is placed on the rotating seat 2 near the blister machine to continue winding the waste.

[0026] A driven gear 421 is provided on the rotating shaft 42 of the reel 4, and a driving gear 5 driven by a rotating motor 6 is provided on the side of the bracket body 1 close to the driven gear 421. The driving gear 5 is meshed with the driven gear 421, and then under the driving action of the rotating motor 6, the reel 4 is driven to rotate to wind and collect the waste.

[0027] A cutting groove 3 is connected between the middle parts of the two supporting cross bars 11, and a cutting assembly 7 is provided for the cutting groove 3. The cutting assembly 7 includes a cutting knife 71 and a protective member 72. The protective member 72 is in an inverted U-shaped style, and the cutting knife 71 is vertically connected to the bottom of the U-shaped portion of the protective member 72 with the blade facing downward, so that the cutting assembly 7 forms an "m"-shaped structure in the longitudinal section. Therefore, when cutting is required, the waste material to be cut is placed above the cutting groove 3, the cutting assembly 7 is taken and pressed down so that the cutting knife 71 is placed in the cutting groove 3, and the protective member 72 is placed on both sides of the cutting groove 3 to achieve cutting of the waste material.

[0028] When the waste winding device of the blister machine of the present embodiment is used, the winding device is placed at the tail of the blister machine, and the empty reel 4 is placed on the rotating seat 2 close to the blister machine. The rotating motor 6 is turned on to drive the reel 4 to rotate, and the waste is wound and collected. After the reel 4 is fully wound, the staff moves the full reel to another rotating seat 2, and places an empty reel 4 on the empty rotating seat 2; at this time, if the waste needs to be cut and then wound on the empty reel 4, the waste is just placed above the cutting groove 3, and the staff needs to take the cutting component 7 from above to press the waste toward the cutting groove 3 to cut off the waste; the cut waste is rewound on the reel 4 of the hole, and the empty reel 4 continues to wind and collect the waste. Based on this, when replacing the empty reel 4, the staff places the full reel on another rotating seat 2, and there is no need to place it anywhere to cause unstable placement, thereby improving the safety and convenience of use. Furthermore, when waste materials need to be cut, it is convenient to cut them off through the cooperation of the cutting groove 3 and the cutting assembly 7, which makes it more convenient to replace the full roll 4 and improves the flexibility of use.

[0029] Furthermore, the width from the blade of the cutting knife 71 to the back of the knife is smaller than the depth of the U-shaped portion of the protective member 72, so that the blade of the cutting knife 71 is completely hidden in the protective member 72, thereby avoiding accidental injuries to the staff and improving the safety of use.

[0030] Furthermore, a hanging piece 8 is provided on the outer side wall of the supporting crossbar 11, and the hanging piece 8 is in an "L" shape with an opening facing upward. When the cutting assembly 7 is not in use, the cutting assembly 7 is hung and stored on the hanging piece 8, which is convenient for the staff to use and avoid the situation of being unable to find it when in use.

[0031] Further, the rotating seat 2 includes a lower rotating seat 22 and an upper rotating seat 21. The lower rotating seat 22 is connected to the supporting cross bar 11, and the upper rotating seat 21 is rotatably connected to the lower rotating seat 22, and arc grooves are provided on the lower side of the upper rotating seat 21 and the upper side of the lower rotating seat 22, and when the upper rotating seat 21 is rotatably covered on the lower rotating seat 22, the two arc grooves form a circular groove, and the rotating shaft 42 passes through the circular groove, so as to facilitate the rotation of the reel 4.

[0032] Further, the rotating seat 2 further comprises a locking member 23. The locking member is arranged on the upper rotating seat 21 and / or the lower rotating seat 22, and locks the upper rotating seat 21 and the lower rotating seat 22 when they are buckled together to prevent the reel 4 from accidentally slipping off.

[0033] In this embodiment, the locking member 23 may be a buckle or other structure as long as it can lock the upper and lower rotating seats.

[0034] Furthermore, the reel 4 includes a winding portion 41 and a rotating shaft 42. The winding portion 41 is in the middle and has an "H"-shaped structure, and the rotating shaft 42 is arranged at both ends of the winding portion 41 and is coaxially arranged with the winding portion 41; the reel 4 is mounted on the rotating seat 2 through the rotating shaft 42 for rotation.

[0035] Furthermore, a circle of concave anti-skid grooves 422 are provided on the rotating shaft 42 to facilitate the staff to grasp, avoid the situation of accidentally dropping the hand, and improve the safety of use.

[0036] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
