Abstract
Description
Technical Field
[0001] This utility model relates to the field of blow molding equipment technology, and in particular to a pen adjustment device for a blow molding machine. Background Technology
[0002] Blow molding machines are key industrial equipment for producing hollow plastic products. They inflate molten plastic preforms into shapes and are widely used in daily chemicals, food and beverage, packaging, automotive, and medical fields. The blow molding process typically includes preform pretreatment, stretch blow molding, cooling and setting, and demolding. During the stretch blow molding process, a pen is inserted into the preform to initially expand its shape with low-pressure gas, followed by high-pressure gas for bidirectional stretching.
[0003] When a blow molding machine performs the inserting action, the angle of the inserting pen usually needs to be adjusted according to the shape of the bottle mouth (e.g., a slanted bottle) and its angle. For example, Chinese utility model patent CN208331612U, entitled "Multi-angle Adjustment Device for Slanted Inserting Pen," includes a base, an inserting pen, an axial sliding mechanism, and an angle adjustment mechanism. The inserting pen is mounted on the mounting base. The angle adjustment mechanism includes an angle adjuster, an angle adjusting screw, and an angle stop pin. The angle adjuster is a hinged four-bar linkage used to drive the axial sliding mechanism and the inserting pen to rotate, thereby adjusting the inserting pen angle. The axial sliding mechanism drives the inserting pen to move axially. Together, these two mechanisms allow the inserting pen to change its position for different bottle mouth angles, meeting requirements and improving production efficiency.
[0004] However, the existing technology still has the following drawbacks: 1. The existing blow molding machine uses an angle adjustment mechanism and an axial sliding mechanism for pen angle and axial displacement adjustment, respectively. Both have many parts, a complex overall structure, and are large and not compact, making pen angle adjustment relatively complicated; 2. All pens are centrally mounted on the same mounting base. When adjusting the pen angle, the axial sliding mechanism and the pen need to be rotated together, which lacks operational flexibility and is prone to causing unnecessary loosening of parts, increasing the number of failure points; 3. The angle adjustment mechanism still requires workers to manually adjust the required pen angle and then lock the position of the angle adjuster through the angle stop pin. The operation is cumbersome, the labor intensity is still high, and the production efficiency of plastic products cannot keep up with the demand. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a pen adjustment device for a blow molding machine.
[0006] The purpose of this utility model is achieved by the following technical solution: a pen adjustment device for a blow molding machine, comprising a pen insertion mechanism, an angle adjustment mechanism, and a main control system. The pen insertion mechanism has a pen insertion base, a transmission component, a pen insertion driver, and a blow molding pen. Several pen insertion bases are arranged along the X-axis. The transmission component is disposed on the pen insertion base. The blow molding pen is connected to the transmission component. The pen insertion driver drives the transmission component after receiving relevant instructions from the main control system to control the axial movement of the pen.
[0007] The angle adjustment mechanism is coaxially assembled with the pen holder base and connected to the transmission assembly, so that the angle adjustment mechanism can rotate coaxially with the pen holder base after receiving relevant instructions from the main control system, thereby adjusting the pen holder angle.
[0008] Furthermore, the transmission assembly has a transmission gear, a first-stage rack, and a second-stage rack. The transmission gear is vertically mounted on the pen holder base, and the first-stage rack and the second-stage rack are both horizontally mounted on the pen holder base and mesh with the transmission gear.
[0009] The first-stage rack is connected to the output end of the pen driver, and the second-stage rack is connected to the blow molding pen. The main control system is electrically connected to and controls the pen driver to start, which drives the first-stage rack to move axially and synchronously transmits the second-stage rack through the transmission gear to control the axial movement of the blow molding pen.
[0010] Furthermore, the pen inserting mechanism also includes a balance bar, which is located on the side of the transmission gear away from the second-stage rack. The balance bar is also arranged parallel to the second-stage rack and connected end to end.
[0011] Furthermore, a fine-tuning component is provided at one end of the second-stage rack and balance bar. The fine-tuning component has a fine-tuning slide rail and a fine-tuning slider assembled with dovetail joints. The fine-tuning slide rail is fixedly connected to one end of the second-stage rack and balance bar. The blow molding pen is connected to the fine-tuning slider and slides along the direction of the fine-tuning slide rail through the fine-tuning slider.
[0012] Furthermore, the angle adjustment mechanism has an angle adjustment rotating seat, an angle adjustment driver or an angle adjustment handwheel for driving the angle adjustment rotating seat to rotate, the angle adjustment rotating seat is coaxially assembled with the pen holder base through a transmission gear, the second-stage rack passes through the angle adjustment rotating seat and rotates synchronously with the angle adjustment rotating seat along the circumference of the transmission gear.
[0013] Furthermore, the angle between the side of the rotating direction of the angle adjustment seat and the vertical line is the pen insertion angle, which ranges from 0 to 45°.
[0014] Furthermore, the pen adjustment device also includes an X-axis adjustment component, which has an X-axis slide rail and an X-axis slide block mounted on the X-axis slide rail. The pen base is disposed on the X-axis slide block, and several pen bases are arranged along the X-axis slide rail direction. The blow-molded pens on two adjacent X-axis slide blocks are arranged in a parallelogram relationship.
[0015] Furthermore, the pen adjustment device also includes a Y-axis adjustment component, which has a Y-axis slide block, which is disposed on the X-axis slide block and slides along the Y-axis.
[0016] Furthermore, the X-axis slide rail and the X-axis slide block are respectively provided with axial adjustment handwheels, which are connected to the X-axis slide block and the Y-axis slide block respectively, and are used to control the X-axis slide block to slide along the X-axis on the X-axis slide rail, and to control the Y-axis slide block to slide along the Y-axis on the X-axis slide block.
[0017] Furthermore, the X-axis slide block is assembled with the X-axis slide rail and the Y-axis slide block respectively using dovetail joints.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: In this embodiment, by coaxially assembling an angle adjustment mechanism on the pen holder base of the pen insert mechanism, the angle adjustment action and axial transmission share a coaxial rotating component, eliminating the relatively independent design of the angle adjustment mechanism and axial sliding mechanism in existing blow molding machines. This reduces a large number of parts, resulting in a more compact overall structure. The angle adjustment and axial movement adjustment of the blow molding pen insert are more coordinated, and operation is more convenient. Furthermore, when adjusting the pen insert angle, the adjustment mechanism only synchronously rotates a portion of the transmission component, without moving the entire pen insert mechanism, avoiding loosening and making operation more flexible and reducing the failure rate. Additionally, the main control system sends relevant instructions to automatically control the adjustment mechanism, reducing labor intensity, shortening the adjustment time of the blow molding pen insert, and improving the production efficiency of plastic products.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0034] like Figure 1-7As shown, a pen adjustment device for a blow molding machine automates the adjustment of the axial movement and insertion angle of the blow molding pen 104, and is widely used in blow molding processes in the daily chemical, food and beverage, packaging, automotive, and medical industries. This pen adjustment device for a blow molding machine includes a pen insertion mechanism 10, an angle adjustment mechanism 20, and a main control system 30. The pen insertion mechanism 10 has a pen insertion base 101, a transmission assembly 102, a pen insertion driver 103, and a blow molding pen 104. Multiple pen insertion bases 101 are arranged parallel to each other along the X-axis, and a transmission assembly 102 is mounted on each base. The output end of the transmission assembly 102 is connected to the blow molding pen 104, and the input end of the transmission assembly 102 is connected to the pen insertion driver 103. The pen insertion driver 103 can be a linear cylinder. The main control system 30 can integrate a PLC or an industrial computer, supporting preset angle and displacement parameters. The pen insertion driver 103 is electrically connected to the main control system 30.
[0035] Therefore, the main control system 30 sends relevant instructions to control the pen driver 103 to start, so that the pen driver 103 drives the transmission component 102 to perform transmission action, converting the rotational motion into the linear motion of the blow molding pen 104, and then controlling the axial movement of the pen through the transmission action of the transmission component 102, so that the blow molding pen 104 is inserted into the preform for blow molding.
[0036] The angle adjustment mechanism 20 is mounted on the pen holder 101 via a coaxial assembly. The angle adjustment mechanism 20 is also connected to the transmission component 102. After receiving relevant instructions from the main control system 30, the angle adjustment mechanism 20 rotates coaxially relative to the pen holder 101. When the angle adjustment mechanism 20 rotates, it drives the transmission component 102 to move, which in turn drives the blow-molded pen 104 to rotate, thereby achieving pen angle adjustment.
[0037] Thus, in this embodiment, by coaxially assembling the angle adjustment mechanism 20 on the pen base 101 of the pen insertion mechanism 10, the angle adjustment action and the axial transmission share a coaxial rotating component, eliminating the relatively independent design of the angle adjustment mechanism and the axial sliding mechanism in existing blow molding machines. This reduces a large number of parts, making the overall structure more compact. The angle adjustment and axial movement adjustment of the blow molding pen 104 are more coordinated, and the operation is more convenient. Moreover, when adjusting the pen angle of the blow molding pen 104, the adjustment mechanism only rotates a portion of the transmission component 102 synchronously, without moving the entire pen insertion mechanism 10, avoiding loosening of the components, making the operation more flexible, and reducing the failure rate. Furthermore, the main control system 30 sends relevant instructions to automatically control the operation of the adjustment mechanism, reducing labor intensity, shortening the adjustment time of the blow molding pen 104, and improving the production efficiency of plastic products.
[0038] The transmission assembly 102 provided in this embodiment has a transmission gear 1021, a first-stage rack 1022, and a second-stage rack 1023. The transmission gear 1021 is vertically pivotally connected to the pen holder base 101. The first-stage rack 1022 and the second-stage rack 1023 are both horizontally arranged on the pen holder base 101. They respectively mesh with the upper and lower tooth surfaces of the transmission gear 1021. Moreover, the first-stage rack 1022 is connected to the output end of the pen holder driver 103, and the second-stage rack 1023 is connected to the blow-molded pen holder 104.
[0039] After receiving the instruction from the main control system 30, the pen inserter driver 103 pushes the first-stage rack 1022 to move axially, then drives the meshing transmission gear 1021 to rotate, and then the transmission gear 1021 drives the meshing second-stage rack 1023 to move axially toward the plastic product, finally realizing the axial extension and retraction of the blow-molded pen inserter 104.
[0040] Therefore, by synchronously transmitting the first-stage rack 1022 and the second-stage rack 1023 through the transmission gear 1021, compared with the traditional lead screw mechanism drive, it saves more planar space, has higher mechanical efficiency, and higher axial positioning accuracy of gear-rack transmission.
[0041] The pen insert mechanism 10 in this embodiment further includes a balance bar 105, which is arranged parallel to the second-stage rack 1023 and connected to the second-stage rack 1023 at both ends to form a parallelogram structure. The balance bar 105 is located on the side of the transmission gear 1021 away from the second-stage rack 1023 and does not contact the transmission gear 1021. Therefore, when adjusting the insertion angle of the blow-molded pen insert 104, the balance bar 105 moves synchronously with the second-stage rack 1023, counteracting the lateral force of the meshing between the second-stage rack 1023 and the transmission gear 1021, preventing the rack from being unbalanced, reducing the vibration amplitude, extending the service life of the gear and rack, and improving the overall adjustment stability.
[0042] Preferably, a fine-tuning component 106 is provided at the end where the second-stage rack 1023 and the balance bar 105 are connected. This fine-tuning component 106 has a fine-tuning slide rail 1061 and a fine-tuning slider 1602. The fine-tuning slide rail 1061 is fixed to the same end of the second-stage rack 1023 and the balance bar 105. The fine-tuning slider 1602 is assembled with the fine-tuning slide rail 1061 using a dovetail joint. The blow molding insert 104 is connected to the fine-tuning slider 1602. During manual fine-tuning, the fine-tuning slider 1602 can slide along the fine-tuning slide rail 1061 to further finely adjust the position of the blow molding insert 104, adapting to preforms of different sizes or mold diameters, and improving the compatibility of the insert adjustment device.
[0043] The angle adjustment mechanism 20 provided in this embodiment has an angle adjustment rotating seat 201 and an angle adjustment driver 202 for driving the angle adjustment rotating seat 201 to rotate. The angle adjustment rotating seat 201 is mounted on the pen holder base 101. The angle adjustment rotating seat 201 is also sleeved on the outer ring of the transmission gear 1021 and assembled with the transmission gear 1021 through a bearing, thereby realizing the coaxial assembly between the angle adjustment rotating seat 201 and the pen holder base 101, and enabling the angle adjustment rotating seat 201 to rotate freely on the pen holder base 101 and the transmission gear 1021. Horizontal insertion holes are opened in the angle adjustment rotating seat 201 and on both sides of the transmission gear 1021, respectively for installing the second-stage rack 1023 and the balance bar 105. The second-stage rack 1023 is installed in the horizontal insertion holes and maintains meshing with the transmission gear 1021.
[0044] Angle adjustment driver 202 is mounted on angle adjustment rotary base 201 and its output shaft is fixed to the flange of angle adjustment rotary base 201. Angle adjustment driver 202 can be a servo motor, stepper motor or pneumatic rotary cylinder. The main control system 30 is electrically connected and controls the angle adjustment driver 202 to start. Angle adjustment driver 202 drives angle adjustment rotary base 201 to rotate on pen holder 101 and synchronously drives the second-stage rack 1023 to rotate around the transmission gear 1021, thereby adjusting the pen insertion angle of blow-molded pen 104.
[0045] like Figure 4 As shown, the angle between the side of the pen angle adjusting rotator 201 in the rotation direction and the vertical line is 0-45°, and preferably 30°.
[0046] Therefore, the angle adjustment mechanism 20 is configured to be coaxially assembled with the pen holder base 101 by setting the angle adjustment rotating seat 201, and the angle adjustment driver 202 is installed on the angle adjustment rotating seat 201. The angle adjustment driver 202 is directly controlled by the main control system 30 to start automatically, thereby automatically driving the angle adjustment rotating seat 201 to adjust the pen holder angle, replacing manual operation and manual locking pin positioning, which not only improves the accuracy of pen holder angle adjustment, but also saves labor intensity.
[0047] like Figure 6 As shown, a manual adjustment mode can also be set when necessary. For example, the angle adjustment handwheel 203 can be fixed on the angle adjustment turntable 201 by a flange, and the angle adjustment turntable 201 can be directly operated manually to rotate, thereby driving the second-stage rack 1023 to adjust the insertion angle of the blow molding pen 104.
[0048] The pen adjustment device provided in this application embodiment also includes an X-axis adjustment component 40 and a Y-axis adjustment component 50. The X-axis adjustment component 40 has an X-axis slide rail 401 and an X-axis slide block 402 mounted on the X-axis slide rail 401. The surface of the X-axis slide rail 401 and the bottom surface of the X-axis slide block 402 are connected by trapezoidal tails to form a dovetail joint structure.
[0049] An axial adjustment handwheel 60 is installed at one end of the X-axis slide rail 401. An X-axis slot is provided in the middle of the X-axis slide rail 401. The axial adjustment handwheel 60 is connected to a lead screw 61, which passes through the X-axis slot. The lead screw 61 is connected to the X-axis slide block 402. The lead screw 61 is rotated by manually operating the axial adjustment handwheel 60. The lead screw 61 drives the X-axis slide block 402 to slide along the X-axis on the X-axis slide rail 401, thereby realizing the X-axis adjustment of the blow molding pen 104.
[0050] Similarly, the Y-axis slide 501 is mounted on the X-axis slide 402 using a dovetail joint connection. A Y-axis slot is correspondingly formed in the middle of the X-axis slide 402. An axial adjustment handwheel 60 is also installed at one end of the X-axis slide 402, connected to a lead screw 61 installed in the Y-axis slot. The lead screw 61 is connected to the Y-axis slide 501. By manually operating the axial adjustment handwheel 60, the lead screw 61 is rotated, causing the Y-axis slide 501 to slide along the Y-axis on the X-axis slide 402, thereby achieving Y-axis adjustment of the blow molding insert 104. This X / Y direction movement range design adapts to the production and processing of preforms of different specifications and mold sizes.
[0051] The dovetail joints between the X-axis slide block 402 and the X-axis slide rail 401, and the Y-axis slide block 501, are all fitted with embedded friction pads 403. The combination of the dovetail joints and the embedded friction pads 403 achieves gapless sliding and self-locking. The friction pads 403 suppress vibration displacement, improve relaxation reliability, and further reduce the failure rate.
[0052] like Figure 5 As shown in the embodiment of this application, several blow molding inserts 104 are arranged along the X-axis slide rail 401 via insert base 101, and adjacent blow molding inserts 104 are arranged in a parallelogram in the XY plane. The parallelogram layout ensures the consistency of the insert angle when multiple blow molding inserts 104 are adjusted synchronously, improves the convenience and accuracy of insert angle adjustment, realizes batch production and processing of bottle preforms, and improves production and processing efficiency.
[0053] The working process of the pen adjustment device provided in this embodiment is as follows:
[0054] 1. Initialization settings
[0055] The main control system 30 loads the mold parameters and manually adjusts the X / Y axis adjustment component 50 to move the pen insert mechanism 10 and the angle adjustment mechanism 20 to the corresponding work positions; the main control system 30 sends a command to control the angle adjustment driver 202 to start, drive the angle adjustment turntable 201 and the blow molding pen insert 104 to rotate to a preset angle (such as 30°), and lock the pen insert angle of the blow molding pen insert 104.
[0056] 2. Blow molding operation
[0057] The pen inserter 103 pushes the first-stage rack 1022 → the transmission gear 1021 rotates → the second-stage rack 1023 extends → the blow molding pen 104 is inserted into the preform for gas injection; after the gas injection is completed, the pen inserter 103 controls the transmission gear 1021 to reverse and retract the pen.
[0058] 3. Dynamic adjustment
[0059] When changing the preform specifications, the main control system 30 synchronously adjusts the angle (0°-45°) and X / Y position of all inserts; the axial position of a single insert is calibrated by the fine-tuning component 106.
[0060] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
