TECHNICAL FIELD

[0001] The utility model relates to tire production equipment field, in detail is a kind of rubber sheet reel positioning device for tire rubber component longitudinal cutting equipment. BACKGROUND

[0002] It is known that in tire rubber component longitudinal cutting process, rubber sheet calender extrudes rubber sheet of different thickness, and rubber sheet is cut into various width specifications of rubber strip by multi-knife longitudinal cutting machine, and they are wound on rubber sheet reel for use in next process. Multi-knife longitudinal cutting machine equipment is composed of rolling cutting winding part, receiving platform, guide opening part, cloth receiving device and the like, and rubber sheet reel is prone to rotate block rotation, slip in winding process, which affects winding rubber sheet efficiency and quality, and there is safety hazard. SUMMARY

[0003] In order to overcome the deficiency of prior art, the utility model provides a rubber sheet reel positioning device, which prevents rotation rubber sheet reel movement, rotation and slip in winding process.

[0004] The utility model discloses a rubber sheet reel positioning device, which is characterized by the following: the rotating block is a cuboid structure, the left end of the rotating block is fixed with a rectangular positioning block, the front end face of the positioning block is higher than the front side face of the rotating block, the right end of the rotating block is fixed with a square fixed seat, the inside of the fixed seat is processed with a cavity, the upper side face and the lower side face of the fixed seat are respectively processed with a strip-shaped upper slot hole and a lower slot hole which are connected with the cavity, the rotating positioning block and the magnet suction ring which are made of iron are arranged in parallel in the cavity from left to right along the radial direction, the upper end and the lower end of the rotating positioning block are respectively fixed with an upper rotating stop rod and a lower rotating stop rod, the upper end of the upper rotating stop rod passes through the upper slot hole and is higher than the upper side face of the rotating block, the lower end of the lower rotating stop rod passes through the lower slot hole and is higher than the lower side face of the rotating block, the middle part of the right end of the fixed seat is processed with a screw hole, a screw rod is screwed in the screw hole, a knob is installed at the right end of the screw rod, and the left end of the screw rod is threadedly connected with the magnet suction ring.

[0005] The utility model has the advantages of simple structure, preventing rotation rubber sheet reel movement, rotation and slip in winding process. BRIEF DESCRIPTION OF DRAWINGS

[0006] The utility model will be further described below in combination with the drawings and examples.

[0007] Figure 1 The utility model has the advantages of simple structure, preventing rotation rubber sheet reel movement, rotation and slip in winding process.

[0008] In the drawings, 1 is an upper rotating stop rod, 2 is a rotating block, 3 is a knob, 4 is a magnet suction ring, 5 is a fixed seat, 6 is a positioning block, 7 is an upper slot hole, 8 is a lower slot hole, 9 is a rotating positioning block, 10 is a lower rotating stop rod, and 11 is a screw rod. Detailed Implementation

[0009] In the figure, this utility model includes a rotating block 2, which is a cuboid structure. A rectangular positioning block 6 is fixed to the left end of the rotating block 2, and the front end face of the positioning block 6 is higher than the front side face of the rotating block 2. A square fixing seat 5 is fixed to the right end of the rotating block 2. A cavity is machined inside the fixing seat 5. The upper and lower sides of the fixing seat 5 are respectively machined with a strip-shaped upper slot hole 7 and a lower slot hole 8 that communicate with the cavity. An iron rotating positioning block 9 and a magnetic [device] are arranged radially from left to right parallel inside the cavity. The upper and lower ends of the magnetic suction ring 4 and the rotating positioning block 9 are respectively fixed with an upper rotating stop bar 1 and a lower rotating stop bar 10. The upper end of the upper rotating stop bar 1 passes through the upper slot hole 7 and is higher than the upper side of the rotating block 2. The lower end of the lower rotating stop bar 10 passes through the lower slot hole 8 and is higher than the lower side of the rotating block 2. A screw hole is machined in the middle part of the right end of the fixing seat 5. A screw 11 is screwed into the screw hole. A knob 3 is installed on the right end of the screw 11. The left end of the screw 11 is threaded together with the magnetic suction ring 4.

[0010] The film roll is fixed on the rectangular rotating block 2 and can be used to wind up the film. During the winding process, the knob 3 rotates and drives the magnetic suction ring 4 to attract the rotating positioning seat 9, which plays the role of positioning and opening. During use, the film roll is clamped between the rotating positioning block 1 and the positioning block 6. The upper rotating stop 1 and the lower rotating stop 10 can rotate at a certain angle in the upper slot 7 and the lower slot 8 and generate friction with the edge of the plastic roll. The clamping force between the rotating stop 1 and the lower rotating stop 10 and the plastic roll is the pushing force generated by the rotation of the knob 3. Rotating the knob 3 in the opposite direction will release the clamping force between the rotating stop 1 and the lower rotating stop 10 and the plastic roll.
