Description

Technical Field

[0001] The present application relates to the field of plastic sheets, and in particular to a blanking device for producing plastic sheets of various specifications. Background Art

[0002] With the increasing domestic demand, the use of thermoformed plastic sheets for packaging is becoming more and more extensive, and the amount used is also increasing year by year. "Sheets with high barrier properties" have become the target of competition among manufacturers. After the plastic sheet is injected or extruded, it will form a continuous sheet, which is generally rolled up by winding equipment when it is unloaded.

[0003] Winding equipment is generally such as Figure 1 As shown, a large motor is used to drive the winding roller to rotate. This has the advantage of facilitating the deflation and inflation of the air shaft, thereby facilitating the removal of the rolled sheet.

[0004] However, due to this unilateral support, the weight of the winding roller and the sheet on the winding roller are supported by the output shaft of the motor. If the specifications of the plastic sheet are small and the number of winding layers is small, it is ok. However, if the specifications of the plastic sheet are large and the number of winding layers is large, it will cause greater pressure on the output shaft of the motor, thus affecting its life.

[0012] The locking fitting portion includes a slide groove and a socket located in the slide groove. The slider is slidably disposed in the slide groove and has a first position and a second position. When in the first position, the insertion rod is inserted into the socket.

[0013] In some embodiments, the insertion hole is located at the bottom of the sliding groove, and when the sliding block is in the second position, the insertion rod is in contact with the bottom of the groove.

[0014] In some embodiments, one end of the support frame away from the supporting roller assembly is recessed inward to form the slide groove, and a limiting groove is formed on the side wall of the slide groove, and a portion of the sliding block passes through the limiting groove.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] The embodiment of the present application provides a feeding device for the production of plastic sheets of various specifications, which can solve the technical problem that if the single-sided supported winding device in the related technology has a large specification of the wound plastic sheet and a large number of wound layers, it will cause greater pressure on the output shaft of the motor, thereby affecting its life.

[0026] like Figure 1 As shown, the left side of the figure is the motor and the right side is the winding roller. Generally, the motor is fixed. In order to facilitate the unloading of the winding roller, the side of the winding roller away from the motor is not supported. The weight of the entire winding roller and the plastic sheet on the winding roller is supported by the motor output shaft, which has a large load.

[0027] In order to solve the above-mentioned technical problems, the present application provides a feeding equipment for the production of plastic sheets of multiple specifications, including a frame 1, a supporting frame 3 and a locking device 5. The frame 1 is provided with a motor, and the motor drive is connected to the winding roller 2, that is, it is connected to the winding roller 2 through the output shaft of the motor. The supporting frame 3 is rotatably arranged on the frame 1, and a supporting roller group 4 is rotatably arranged on the supporting frame 3; the locking device 5 includes a locking part 51 and a locking matching part 52, one of which is arranged on the frame 1, and the other is correspondingly arranged on the supporting frame 3. The locking part 51 and the locking matching part 52 can cooperate with each other. When the locking part 51 and the locking matching part 52 cooperate with each other, the supporting roller group 4 supports the winding roller 2 from bottom to top.

[0028] like Figure 2 As shown, at this time, the locking portion 51 and the locking matching portion 52 are in a mutually matched state. At this time, the supporting roller group 4 supports the winding roller 2 from bottom to top. In this state, the weight of the winding roller 2 and the plastic sheet on its surface will be partially supported by the supporting frame 3, thereby reducing the load on the motor output shaft. For plastic sheets of different specifications, such as wider widths and thicker thicknesses, their weight will be correspondingly heavier. Through the support of the supporting roller group 4, the load on the motor output shaft can be greatly reduced.

[0029] Further, see Figure 2 The support roller group 4 includes two sub-support rollers 41. When the locking portion 51 and the locking matching portion 52 cooperate with each other, the two sub-support rollers 41 are in contact with the winding roller 2, and the axes of the two sub-support rollers 41 are at the same distance from the axis of the winding roller 2.

[0030] This design ensures that the two sub-support rollers 41 ensure balanced force on the winding roller 2 when supporting the winding roller 2, and the sub-support rollers 41 are in rolling contact with the winding roller 2, thereby reducing the friction of the winding roller 2 when it rotates.

[0031] In a specific embodiment, the locking portion 51 includes a slider 511, a connecting rod 512, an insertion rod 513 and an elastic member 514. The two ends of the connecting rod 512 are rotatably arranged on the slider 511 and the frame 1 respectively. The elastic member 514 connects the insertion rod 513 and the slider 511, and the insertion rod 513 is arranged to penetrate the slider 511.

[0032] The locking fitting portion 52 includes a slide groove 521 and a socket 522 located in the slide groove 521 . The slider 511 is slidably disposed in the slide groove 521 and has a first position and a second position. When in the first position, the insertion rod 513 is inserted into the socket 522 .

[0033] like Figure 2As shown, when the locking portion 51 and the locking matching portion 52 are engaged, the slider 511 is in the first position in the slide groove 521, and the insertion rod 513 is inserted into the insertion hole 522, and the connecting rod 512, the support frame 3 and the frame 1 form a stable triangular structure. Only when the insertion rod 513 is disengaged from the insertion hole 522, the slider 511 can move to another position, that is, the second position.

[0034] The two ends of the connecting rod 512 are rotatably set on the slider 511 and the frame 1 respectively. When the supporting frame 3 is lifted upward, the slider 511 will slide from the two ends of the slide groove 521 to the middle and move directly to the first position. At this time, the insertion rod 513 is inserted into the insertion hole 522, and the sub-support roller 41 will also contact the winding roller 2.

[0035] In order to realize automatic snap-in, the insertion hole 522 is located at the bottom of the sliding groove 521 , and when the sliding block 511 is in the second position, the insertion rod 513 is in contact with the bottom of the groove.

[0036] In the present application, the slider 511 has only two positions in the slide groove 521, namely the first position and the second position. When in the first position, the rod 513 is inserted into the insertion hole 522. When in other positions, the rod 513 fits the bottom of the groove. At this time, the elastic member 514 is in a stretched state or a compressed state. When the slider 511 moves to the first position, the rod 513 is inserted into the insertion hole 522, and the elastic member 514 automatically resets.

[0037] In a specific implementation scheme, one end of the support frame 3 away from the support roller group 4 is recessed inward to form the slide groove 521 , and a limiting groove 6 is formed on the side wall of the slide groove 521 , and a portion of the slider 511 passes through the limiting groove 6 .

[0038] like Figure 2 As shown, this design can prevent the slider 511 from falling off from the slide groove 521.

[0039] Specifically, the elastic member 514 is a spring, and the spring is sleeved on the insertion rod 513, and the two ends of the spring are respectively on the insertion rod 513 and the support frame 3.

[0040] See also Figure 2 In the present application, when in another position, that is, the second position, the rod 513 fits the bottom of the groove, and the spring is in a stretched state. When the slider 511 moves to the first position, the rod 513 is inserted into the socket 522, and the spring automatically resets.

[0041] In order to facilitate pulling the insertion rod 513 so as to separate the insertion rod 513 from the insertion hole 522 , a pull ring is provided on the insertion rod 513 .
