[0032] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1-4 A strip rubber extrusion molding device is shown, comprising an extrusion tank 1 with a feed port on the surface, a feeder 21 is rotatably installed inside the extrusion tank 1, a driving motor 2 is installed on one side of the extrusion tank 1, and the output end of the driving motor 2 is connected to one end of the feeder 21, a vertical plate 3 is installed on the other side of the extrusion tank 1, and a rectangular discharge port is arranged on the other side of the extrusion tank 1, a through slot matching the discharge port is penetrated inside the vertical plate 3, an elastic constraint 12 is installed inside the through slot, and a transition frame 13 is connected to the tail end of the elastic constraint 12;

[0035] A second electric extension rod 5 is vertically installed on the top of the vertical plate 3, and the power end of the second electric extension rod 5 is movably connected to an inclined plate member, and the inclined plate member includes a sliding sleeve plate 6 and a movable extrusion plate 7, wherein the movable end of the sliding sleeve plate 6 is connected to the power end of the second electric extension rod 5 through a hinge ball, and the surface of the vertical plate 3 is rotatably connected to a round rod, and the surface of the round rod is fixedly connected to the movable extrusion plate 7, and the top end of the movable extrusion plate 7 is connected to the end of the sliding sleeve plate 6;

[0036] An extrusion groove corresponding to the transition frame 13 is provided inside the movable extrusion plate 7, and an elastic frame strip 14 is installed on the inner wall of the extrusion groove. The elastic frame strip 14 is connected to the outer surface of the transition frame 13. Two No. 1 electric extension rods 4 are installed at the bottom of the fixed end of the No. 2 electric extension rod 5, and a horizontal sensor 11 located between the two No. 1 electric extension rods 4 is installed on the top surface of the transition frame 13.

[0037] Specifically, the driving motor 2 is used to drive the feeder 21 to extrude the rubber in the extrusion tank 1, and then the extruded rubber strip is able to enter the elastic constraint 12 through the through groove in the vertical plate 3, and then enter the transition frame 13, and then be extruded through the extrusion groove in the movable extrusion plate 7 to complete the corresponding cutting.

[0038] When adjusting the angle of the bevel cutting, the second electric extension rod 5 can be used to adjust the length. During the process of adjusting the length of the second electric extension rod 5, the length of the sliding sleeve 6 is adjusted accordingly, so that the vertical plate 3, the second electric extension rod 5 and the inclined plate can maintain a complete triangle (due to the inclined plate and the vertical plate 3). By adjusting the length of the second electric extension rod 5 (such as Figure 5-6 As shown), the angle between the vertical plate 3 and the inclined plate can be changed (in this process, the elastic constraint 12 is affected by the change in the horizontal displacement of the movable extrusion plate 7, and elastic stretching changes will occur), and then the horizontal sensor 11 is used to detect the horizontal change state of the transition frame 13 after the length of the No. 2 electric extension rod 5 is adjusted, and the two No. 1 electric extension rods 4 are used to adjust the horizontal state of the transition frame 13 (due to the existence of the elastic frame strip 14, there is operating space for the transition frame 13 when leveling), so that the transition frame 13 can be restored to a horizontal state.

[0039] A No. 3 electric extension rod 9 is installed on the surface of the movable extrusion plate 7. The power end of the No. 3 electric extension rod 9 is connected to a cutting knife 8 parallel to the surface of the movable extrusion plate 7, and the cross-sectional length of the cutting knife 8 is greater than the cross-sectional length of the extrusion groove.

[0040] Specifically, when the bevel cutting is performed, the No. 3 electric extension rod 9 is started to drive the cutting knife 8 to move upward, so that the rubber strip protruding from the surface of the extrusion groove can be cut at the bevel.

[0041] Fig. 9 As shown, a replacement plate 15 is detachably installed inside the end of the transition frame 13 facing away from the vertical plate 3 , and an extrusion through hole is provided inside the replacement plate 15 .

[0042] Specifically, when the rubber strip with a non-rectangular cross section is bevel-cut, the replacement plate 15 (such as Fig.10 As shown in the figure, the strip rubber with rectangular and circular cross-sections can be replaced by installing it inside the transition frame 13.

[0043] Figure 7 It is shown that the elastic restraint member 12 includes an elastic strip 121 and a restraint strip 122 , wherein the restraint strip 122 is located outside the elastic strip 121 , the restraint strip 122 is made of elastic material, and the interior of the restraint strip 122 is filled with electrohardening colloid.

[0044] Specifically, when the transition frame 13 moves following the movable extrusion plate 7, the elastic strip 121 will be deformed accordingly. After leveling, the horizontal sensor 11 will send a start signal to the constraint strip 122. At this time, the constraint strip 122 is energized, and the internal electrohardening colloid changes from the original colloid state (the colloid state will not affect the synchronous deformation of the constraint strip 122 following the elastic strip 121) to a solidified state, thereby making the elastic constraint member 12 solidified (such as Figure 8 As shown), the rubber extruded from the extrusion tank 1 will not fall and deform due to gravity when passing through the elastic constraint member 12, thereby affecting the smoothness of the rubber transmission.

[0045] A refrigerator is installed on the surface of the vertical plate 3 , and the output end of the refrigerator is connected to a hose whose tail end extends into the movable extrusion plate 7 , and the hose is located outside the elastic frame strip 14 .

[0046] Specifically, the refrigerator can assist in cooling the extruded rubber at the elastic frame strip 14, thereby increasing the degree of hardening of the strip rubber after cutting at the extrusion groove, thereby reducing the possibility of deformation of the strip rubber during the cutting process and effectively ensuring the consistency of the cut surface shape when the strip rubber is cut obliquely.

[0047] It also includes a control and adjustment system, which includes a horizontal correction module, an angle adjustment module and a cutting execution module, wherein the horizontal correction module is connected to the horizontal sensor 11 and the No. 1 electric extension rod 4 by signal, and is used to restore the transition frame 13 to a horizontal state after the angle is adjusted, the angle adjustment module is connected to the No. 2 electric extension rod 5 by signal, and is used to adjust the angle between the movable extrusion plate 7 and the vertical plate 3, and the cutting execution module is connected to the No. 3 electric extension rod 9 by signal, and is used to perform a bevel cutting operation.

[0048] The control and regulation system further comprises a curing constraint module, wherein the curing constraint module is connected to the constraint strip 122 by signal, and is used for energizing and curing the constraint elastic strip 121 after the transition frame 13 returns to a horizontal state.

[0049] Specifically, when performing horizontal adjustment, the length adjustment of the two No. 1 electric extension rods 4 can assist the transition frame 13 to restore to a horizontal state after the angle adjustment, and then after the horizontal sensor 11 detects that the transition frame 13 has restored to a horizontal state, the length adjustment of the two No. 1 electric extension rods 4 is stopped, and an electrical signal is sent to the constraint bar 122, so that the elastic constraint 12 remains in a solidified state.

[0050] The second implementation method:

[0051] Figure 1 and Figure 3 It is shown that a rotating motor 10 is installed on the surface of the movable extrusion plate 7 facing away from the vertical plate 3, and the output end of the rotating motor 10 is connected to the fixed end surface of the third electric extension rod 9.

[0052] A displacement sensor is installed inside the cutting blade 8 , and the displacement sensor is connected to the rotating motor 10 for signal transmission.

[0053] Different from the first embodiment, this embodiment is mainly used when the cutting knife 8 needs to be withdrawn to the original waiting state after cutting and will pass through the extrusion groove position again. The rubber re-extruded in the extrusion groove may be cut, causing unnecessary waste (because the time period from the cutting completion to the resetting process of the cutting knife 8 is relatively short, so the length of the extruded rubber will also be relatively short, so the cut rubber strip will not meet the specified length, thus causing waste).

[0054] Specifically, after the cutting is completed (that is, the displacement distance of the cutting knife 8 reaches the distance for cutting completion), the rotating motor 10 is then started to drive the No. 3 electric extension rod 9 in the extended state and the cutting knife 8 to rotate a certain angle, so that the cutting knife 8 is separated from the surface of the movable extrusion plate 7. After that, the No. 3 electric extension rod 9 is reset to the length of the waiting state, and the rotating motor 10 rotates in the opposite direction, so that the cutting knife 8 is parallel to the surface of the movable extrusion plate 7 again (such as Fig.11 as shown).

[0055] In summary, the present application utilizes the cooperation of the No. 2 electric extension rod 5 and the inclined plate and the vertical plate 3. By adjusting the length of the No. 2 electric extension rod 5, the length of the sliding sleeve plate 6 is driven to change so that the length of the inclined plate changes synchronously, thereby adjusting the angle between the vertical plate 3 and the inclined plate, and then achieving the purpose of adjusting the inclined surface angle of the movable extrusion plate 7. In this process, the No. 1 electric extension rod 4 is used to restore the transition frame 13 that is tilted due to the adjustment of the angle to a horizontal state, and then the constraint strip 122 is used to adjust the curing of the elastic strip 121, so that the extrusion path of the rubber between the extrusion tank 1 and the transition frame 13 is in a smooth state, and the rotating motor 10 is used to rotate the cutting knife 8 after cutting, so as to reduce the secondary invalid cutting of the rubber extruded on the surface of the extrusion groove when the cutting knife 8 returns to the original path, thereby avoiding waste.

[0056] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
