Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to an auxiliary tooling for plastic film blowing. Background Technology

[0002] A plastic film blowing machine is a specialized piece of machinery used to produce plastic films. It primarily heats and melts plastic raw materials, then extrudes them through a specific die to form a tubular plastic melt. Compressed air is then introduced into the tube, causing the melt to inflate into a bubble shape under air pressure and continuously pulled upwards. Simultaneously, cooling devices such as cooling air rings are used to cool and shape the melt. Finally, through processes such as traction and winding, it is processed into a continuous plastic film with a certain width and thickness. Different plastic materials have different thermal properties; their melting points and thermal conductivity vary. When processing plastic materials with higher melting points and relatively slower heat dissipation, it is often necessary to increase the size of the air outlet to enhance the cooling effect and ensure adequate cooling. Conversely, for materials with lower melting points and faster heat dissipation, a smaller air outlet may be sufficient to meet the cooling requirements, preventing over-cooling from affecting the film's flexibility and transparency. The inability to flexibly adjust the air outlet size makes it difficult to control the cooling effect according to the diverse requirements of different customers regarding film thickness and material, thus limiting the types of plastic films that can be produced.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Reference Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides an auxiliary tooling for plastic film blowing. The auxiliary tooling for plastic film blowing includes a main component 100 and an adjustment component 200. The two work together to adjust the size of the air outlet according to the film thickness requirements. When the film is thick, the air outlet is increased to ensure sufficient cooling and uniform shaping. When the film is thin, the air outlet is reduced to prevent excessive cooling, thereby accurately controlling the cooling effect of films of different thicknesses.

[0031] The main component 100 includes a blown film machine 101, a blower 102 fixed to the bottom of the blown film machine 101, a base 103 fixed to the bottom of the blower 102, and a climbing ladder 104 provided on one side of the blown film machine 101.

[0032] The blown film machine 101 can process plastic raw materials into continuous plastic films through a series of processes. The blown film machine 101 is existing technology and will not be described in detail here. The blower 102 is fixed at the bottom of the blown film machine 101 to provide the required compressed air for the blown film process and help the melt expand and form. The base 103 is used to provide stable support for the blown film machine 101. The climbing ladder 104 facilitates personnel to climb to the corresponding position and to operate the blown film machine 101. When blowing air into the plastic film using the blown film machine 101, an auxiliary frame is fitted on the outside of the plastic film to support it and prevent it from shifting during blowing. The auxiliary frame is installed above the blown film machine 101 by a bracket. The auxiliary frame is existing technology and will not be described in detail here.

[0033] An adjustment assembly 200 is installed on a blown film machine 101 and includes an adjustment component 201. The adjustment component 201 includes an adjustment plate 201a. A guide strip 201b is fixed to the top of the adjustment plate 201a. A rotating disk 201c is sleeved on the outside of the guide strip 201b. The rotating disk 201c and the guide strip 201b are movably connected. A gear 201d is provided on one side of the rotating disk 201c.

[0034] The rotating disk 201c is rotatably connected to the blown film machine 101 via a rotating shaft. When it is necessary to adjust the air outlet of the blown film machine 101, the rotating disk 201c can be rotated by rotating the gear 201d. At this time, the rotation of the rotating disk 201c will drive the guide bar 201b to move. When the guide bar 201b moves, it will drive the adjusting plate 201a to move. Then, the size of the air outlet can be adjusted by moving the adjusting plate 201a.

[0035] Example 2

[0036] Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the adjustment component 200 also includes a support member 202, which includes a support bar 202a. The support bar 202a is fixed to the bottom of the adjustment plate 201a, and a support plate 202b is sleeved on the outside of the support bar 202a. The support bar 202a and the support plate 202b are movably connected.

[0038] The support plate 202b is fixed to the inner wall of the blown film machine 101. When the adjusting plate 201a moves, it can drive the support bar 202a to move. At this time, the support bar 202a can move on the support plate 202b, thereby supporting the adjusting plate 201a and preventing the adjusting plate 201a from shifting when it moves.

[0039] Specifically, a belt 202c is fitted around the outside of the gear 201d, and a pulley 202d is installed inside the belt 202c.

[0040] Both gear 201d and pulley 202d are rotatably connected to the inner wall of blown film machine 101 via a rotating shaft. When pulley 202d rotates, it can drive belt 202c to rotate. At this time, the rotation of belt 202c can drive gear 201d to rotate, thereby adjusting the size of the air outlet.

[0041] Specifically, the rotating disk 201c has an extrusion groove X corresponding to the guide bar 201b, and the guide bar 201b slides within the extrusion groove X.

[0042] When the rotating disk 201c rotates, it can drive the extrusion groove X to extrude the guide bar 201b and make it move. At this time, the movement of the guide bar 201b can drive the adjustment plate 201a to move.

[0043] Specifically, a tooth groove Y corresponding to the gear 201d is opened on one side of the rotating disk 201c, and the tooth groove Y and the gear 201d mesh.

[0044] Rotating gear 201d causes its teeth to rotate. Since gear 201d meshes with tooth groove Y, the teeth can squeeze tooth groove Y, thereby causing the rotating disk 201c to rotate.

[0045] Specifically, the support plate 202b has a support groove Z corresponding to the support bar 202a, and the support bar 202a slides within the support groove Z.

[0046] When the adjusting plate 201a moves the support bar 202a, the support bar 202a slides in the support groove Z. At this time, the adjusting plate 201a can be rotated by the guide of the support groove Z, so that it can be circularly contracted, thereby adjusting the air outlet.

[0047] Specifically, the adjustment component 200 also includes a limiting member 203, which includes a limiting strip 203a. The bottom of the pulley 202d is provided with a limiting groove S corresponding to the limiting strip 203a, and the limiting strip 203a is located in the limiting groove S.

[0048] After rotating the pulley 202d to the designated position and adjusting the air outlet to the designated size, in order to prevent the pulley 202d from rotating on its own, the pulley 202d can be limited by engaging the limit strip 203a and the limit groove S.

[0049] Example 3

[0050] Reference Figures 1 to 7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0051] Specifically, a connecting plate 203b is fixed to the bottom of the limiting strip 203a, and a pressure plate 203c is fixed to one end of the connecting plate 203b.

[0052] When it is necessary to release the limit on pulley 202d, the lower pressure plate 203c is moved, which in turn drives the connecting plate 203b to move. At this time, the movement of the connecting plate 203b can separate the limit strip 203a and the limit groove S, thereby releasing the limit on pulley 202d and allowing it to rotate to adjust the size of the air outlet.

[0053] Specifically, a movable column 203d is fixed to the top of the lower pressure plate 203c, and a force-bearing plate 203e is fixed to the top of the movable column 203d.

[0054] The movable column 203d is inserted into the top of the climbing ladder 104. The movable column 203d and the climbing ladder 104 are movably connected. The user can reach the pulley 202d and operate it by standing at the top of the climbing ladder 104. At this time, the user can step on the force plate 203e to press it down. Then, by moving the force plate 203e, the movable column 203d can be moved, thereby separating the limit strip 203a and the limit groove S, and thus rotating the pulley 202d.

[0055] Specifically, a spring 203f is fixed at the bottom of the climbing ladder 104, and one end of the spring 203f is fixed to the top of the lower pressure plate 203c.

[0056] When the pressure plate 203c is pressed down, it can apply a pulling force to the spring 203f. At this time, the limiting strip 203a will separate from the limiting groove S and release the limiting of the pulley 202d. After the pulley 202d is rotated to adjust the size of the air outlet, the user goes up and down the climbing ladder 104 and then releases the pressure on the force plate 203e. The rebound force of the spring 203f can drive the force plate 203e back to its original position, so that the limiting strip 203a will re-engage with the limiting groove S, thereby limiting the pulley 202d.

[0057] When in use, if the size of the air outlet of the blown film machine 101 needs to be adjusted, the operator climbs to the corresponding position via the climbing ladder 104 to prepare for the subsequent adjustment operation. Standing on the top of the climbing ladder 104, the operator steps on the force plate 203e. The force plate 203e is pressed, causing the movable column 203d to move. The movement of the movable column 203d causes the lower pressure plate 203c to press down. The lower pressure plate 203c applies a pulling force to the spring 203f. At the same time, the lower pressure plate 203c drives the limiting strip 203a to move through the connecting plate 203b, so that the limiting strip 203a and the limiting strip 203a... The bottom limiting groove S of the pulley 202d separates, releasing the limiting of the pulley 202d. Then, the pulley 202d is rotated, which drives the belt 202c to rotate. The belt 202c rotates, which drives the gear 201d connected to it to rotate. The gear 201d meshes with the tooth groove Y on one side of the rotating disk 201c. The teeth press against the tooth groove Y, causing the rotating disk 201c to rotate. The rotation of the rotating disk 201c causes its pressing groove X to press against the guide bar 201b, causing it to move. The movement of the guide bar 201b causes the adjusting plate 201a to move. When the adjusting plate 201a moves, its bottom support bar 202a slides in the support groove Z of the support plate 202b, causing the adjusting plate 201a to move in a circular retraction motion, thereby adjusting the size of the air outlet. After the operation is completed, the operator goes down the climbing ladder 104 to release the pressure on the force plate 203e. At this time, the rebound force of the spring 203f drives the force plate 203e back to its original position, thereby causing the limiting bar 203a and the limiting groove S to engage, limiting the pulley 202d, so that the blown film operation can continue.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
