[0004]现有的拉杆箱胶条挤出成型加工设备在应对不同截面形状的拉杆箱胶条加工需求时,存在明显的局限性——每当需要生产不同截面形状的拉杆箱胶条时,操作人员都必须手动将当前的挤出头进行拆卸,并更换为适配新截面形状的挤出头,这一繁琐的步骤不仅大大降低了拉杆箱胶条的整体加工效率,还显著增加了操作难度和人力成本

Benefits of technology

[0030]In this invention, when the first telescopic rod extends, it drives the extrusion head rotation mechanism to move laterally away from the extruder body's discharge port via the assembly plate. Then, when the drive motor runs, it drives the active bevel gear to rotate, which in turn drives the rotating rod to rotate via the driven bevel gear. When the rotating rod rotates, it drives the end plate to rotate, thereby aligning the extrusion holes of different shapes with the extruder body's discharge port. Finally, when the first telescopic rod retracts, it drives the extrusion head rotation mechanism to move closer to the extruder body's discharge port via the assembly plate until the end plate is pressed against its side surface. This allows for the processing of trolley case rubber strips with different cross-sectional shapes, thereby achieving automatic adjustment according to the production and processing needs of the trolley case rubber strip shape and improving processing efficiency.

Description

Technical Field

[0001] This invention relates to the field of extrusion technology for luggage rubber strips, and in particular to an extrusion molding equipment and method for luggage rubber strips. Background Technology

[0002] Suitcase sealing strips are sealing strips, decorative strips, or structural support strips on the edges of suitcases. They are usually made of plastic (such as PVC, ABS, TPU) and their functions include sealing and waterproofing, decorative enhancement, structural support, and edge protection.

[0003] The trolley case rubber strip extrusion molding equipment is a plastic processing machine specially designed for producing edge sealing strips, decorative strips, or structural support strips for trolley cases. Its core function is to transform plastic raw materials (such as PVC, ABS, TPU, etc.) into continuous box strips with specific cross-sectional shapes through the extrusion molding process.

[0004] Existing trolley case rubber strip extrusion molding equipment has significant limitations in handling the processing needs of trolley case rubber strips with different cross-sectional shapes. Whenever it is necessary to produce trolley case rubber strips with different cross-sectional shapes, the operator must manually disassemble the current extrusion head and replace it with an extrusion head that is compatible with the new cross-sectional shape. This cumbersome step not only greatly reduces the overall processing efficiency of trolley case rubber strips, but also significantly increases the difficulty of operation and labor costs.

[0005] In view of this, the present invention provides a rolling case rubber strip extrusion molding equipment and method to solve the above problems. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a trolley case rubber strip extrusion molding processing equipment, comprising an extruder cabinet, an extruder body installed on the upper surface of the extruder cabinet, a hopper connected to the upper surface of the extruder body, a controller installed on the upper surface of the extruder cabinet to realize the operation control of the extruder body, an extrusion head adjustment assembly installed at the end of the extruder body, and a cooling assembly located on one side of the extruder cabinet and at the extrusion end of the extruder body;

[0007] The extruder head adjustment assembly includes an extruder head rotating part installed at the discharge end of the extruder body, and a telescopic part installed between the extruder head rotating part and the extruder body;

[0009] Preferably, the extruder head rotating part includes an extruder head rotating mechanism disposed at the end of the extruder body, and a driving mechanism mounted on the side surface of the extruder head rotating mechanism.

[0010] Preferably, the extruder head rotation mechanism includes an outer ring, a limiting groove formed on the inner wall of the outer ring, an end plate formed on the inner wall of the outer ring and abutting against the end of the extruder body, an extrusion hole formed on the surface of the end plate, and an arc-shaped protrusion connected to the outer surface of the end plate and adapted to the size of the limiting groove.

[0011] The center of the end plate is located on the central axis of the outer ring, and the extrusion holes on the surface of the end plate are arranged in five groups with different shapes. The distance between the five groups of extrusion holes and the center of the end plate is the same, and the highest extrusion hole is aligned with the discharge end of the extruder body.

[0012] Preferably, the drive mechanism includes an assembly plate, a bearing housing mounted on the upper surface of the assembly plate, a rotating rod penetrating the interior of the bearing housing and connected to the side surface of the end plate, a driven bevel gear connected to the end of the rotating rod, a drive motor mounted on the surface of the bearing housing, and a driving bevel gear connected to the output end of the drive motor and meshing with the driven bevel gear.

[0013] The center of the end plate is located on the central axis of the rotating rod.

[0014] Preferably, the telescopic part includes an assembly base connected to the bottom side of the end of the extruder body, a first telescopic rod connected to the upper surface of the assembly base and connected to the assembly plate, and a first guide mechanism disposed between the assembly plate and the assembly base.

[0015] The first guiding mechanism includes a guide groove formed on the upper surface of the inner side wall of the mounting base, and a guide block connected to the side surface of the mounting plate and adapted to the guide groove.

[0016] Preferably, a monitoring and cutting assembly is mounted on the surface of the outer ring. The monitoring and cutting assembly includes a cutting part mounted on the top of the outer ring and a sensing probe mounted on the bottom side surface of the outer ring and pointing vertically upward.

[0017] The cutting section includes a first vertical plate connected to the top of the outer ring, a second telescopic rod installed on the side surface of the first vertical plate, a docking plate connected to the telescopic end of the second telescopic rod, and a cutter disposed on the side surface of the docking plate and connected by a clamping mechanism.

[0018] Preferably, the clamping mechanism includes a circular hole formed on the surface of the second telescopic rod, a first crossbar passing through the inside of the circular hole and connected to the side surface of the cutter, a limiting block connected to the end of the first crossbar, and a spring bar connected between the second telescopic rod and the cutter and fitted onto the surface of the first crossbar.

[0019] Preferably, the pressure roller section includes a second vertical plate disposed inside the cooling pool, a pressure roller mechanism installed on the side surface of the second vertical plate and arranged linearly at equal intervals, a third telescopic rod installed on the outer surface of the cooling pool and connected to the second vertical plate, and a second guide mechanism disposed between the cooling pool and the second vertical plate.

[0020] The second guiding mechanism includes a guide rail connected to the inner wall of the cooling pool, and a guide sleeve connected to the side surface of the second vertical plate and adapted to the guide rail.

[0021] Preferably, the pressure roller mechanism includes a second crossbar connected to the side surface of the second vertical plate, a bearing ring sleeved on the surface of the second crossbar, and a pressure roller connected to the outer surface of the bearing ring.

[0022] A method for extruding and molding rubber strips for suitcases includes the following steps:

[0023] S1: Adjustment of the extrusion head of the trolley case rubber strip. Check and control the equipment of the extrusion molding equipment, and then adjust the position of the extrusion head according to the shape of the trolley case rubber strip to be produced and processed by setting the extrusion head adjustment component.

[0024] S2: Raw material proportioning and mixing and drying: The main material, plasticizer, stabilizer, lubricant, color masterbatch and filler of the luggage rubber strip are added to the high-speed mixer in a quantitative manner and mixed. Then the mixed raw materials are sent to the dehumidifying dryer. Finally, the dried mixed raw materials are added to the hopper.

[0025] S3: The plasticizing and molding process of the trolley case rubber strip extruder involves the raw material inside the hopper entering the interior of the extruder body and being melted and conveyed. Then, the molten raw material is extruded through the extrusion hole to form the trolley case rubber strip.

[0026] S4: Monitoring and cutting of waste luggage rubber strips. The extruded luggage rubber strips are sensed by a sensor probe. When the extruded luggage rubber strips curl and deform, the cutting part cuts the luggage rubber strips.

[0027] S5: Pulling and limiting of luggage rubber strip. The standard luggage rubber strip is limited by the cooling component and then connected to the pulling mechanism, which pulls the rubber strip.

[0028] S6: Cooling and shaping of the luggage rubber strip. The luggage rubber strip is cooled and shaped by the internal water during the cooling process of the cooling component.

[0029] The beneficial effects of this invention are:

[0030] In this invention, when the first telescopic rod extends, it drives the extrusion head rotation mechanism to move laterally away from the extruder body's discharge port via the assembly plate. Then, when the drive motor runs, it drives the active bevel gear to rotate, which in turn drives the rotating rod to rotate via the driven bevel gear. When the rotating rod rotates, it drives the end plate to rotate, thereby aligning the extrusion holes of different shapes with the extruder body's discharge port. Finally, when the first telescopic rod retracts, it drives the extrusion head rotation mechanism to move closer to the extruder body's discharge port via the assembly plate until the end plate is pressed against its side surface. This allows for the processing of trolley case rubber strips with different cross-sectional shapes, thereby achieving automatic adjustment according to the production and processing needs of the trolley case rubber strip shape and improving processing efficiency.

[0031] In this invention, when the rubber strip of a trolley case monitored by the sensor probe is found to be curled, the second telescopic rod is extended by the sensor switch. When the second telescopic rod extends, it drives the docking plate to move downward and drives the cutter to move downward through the clamping mechanism. The downward movement of the cutter can cut the rubber strip of the trolley case, thereby automatically removing the unqualified rubber strip of the trolley case and improving the automation level of the device.

[0032] In this invention, the rubber strip of the trolley case passes through the bottom of the pressure roller mechanism and falls onto the upper surface of the conveyor roller. Then, the third telescopic rod retracts, causing the second vertical plate to move downward. When the second vertical plate moves downward, it causes the pressure roller mechanism to move downward. When the pressure roller mechanism moves downward, it presses the rubber strip of the trolley case into the water body of the cooling pool, thereby eliminating the need for manual pulling from inside the water body and reducing the difficulty of operation.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example 1

[0050] This invention relates to a rolling case rubber strip extrusion molding processing equipment, such as... Figure 1 - Figure 6 As shown, it includes an extruder cabinet 1, an extruder body 2 installed on the upper surface of the extruder cabinet 1, a hopper 3 connected to the upper surface of the extruder body 2, a controller 4 installed on the upper surface of the extruder cabinet 1 to realize the operation control of the extruder body 2, an extrusion head adjustment assembly 5 installed at the end of the extruder body 2, and a cooling assembly 7 located on one side of the extruder cabinet 1 and at the extrusion end of the extruder body 2.

[0051] The extruder head adjustment assembly 5 includes an extruder head rotating part 51 installed at the discharge end of the extruder body 2, and a telescopic part 52 installed between the extruder head rotating part 51 and the extruder body 2.

[0052] The extruder head rotating part 51 includes an extruder head rotating mechanism 511 disposed at the end of the extruder body 2, and a drive mechanism 512 mounted on the side surface of the extruder head rotating mechanism 511.

[0053] The extruder head rotation mechanism 511 includes an outer ring 5111, a limiting groove 5112 formed on the inner wall of the outer ring 5111, an end plate 5113 formed on the inner wall of the outer ring 5111 and abutting against the end of the extruder body 2, an extrusion hole 5114 formed on the surface of the end plate 5113, and an arc-shaped protrusion 5115 connected to the outer surface of the end plate 5113 and adapted to the size of the limiting groove 5112. In this embodiment, when the end plate 5113 rotates, it can drive the arc-shaped protrusion 5115 to rotate inside the limiting groove 5112, thereby maintaining the stability of the rotation of the end plate 5113.

[0054] The center of the end plate 5113 is located on the central axis of the outer ring 5111, and the extrusion holes 5114 on the surface of the end plate 5113 are set in five groups with different shapes. The distance between the five groups of extrusion holes 5114 and the center of the end plate 5113 is the same, and the highest extrusion hole 5114 is aligned with the discharge end of the extruder body 2.

[0055] The drive mechanism 512 includes an assembly plate 5121, a bearing housing 5122 mounted on the upper surface of the assembly plate 5121, a rotating rod 5123 penetrating the interior of the bearing housing 5122 and connected to the side surface of the end plate 5113, a driven bevel gear 5124 connected to the end of the rotating rod 5123, a drive motor 5125 mounted on the surface of the bearing housing 5122, and a driving bevel gear 5126 connected to the output end of the drive motor 5125 and meshing with the driven bevel gear 5124; the center of the end plate 5113 is located on the central axis of the rotating rod 5123. In this embodiment, when the drive motor 5125 is running, it can drive the driving bevel gear 5126 to rotate. When the driving bevel gear 5126 rotates, it drives the driven bevel gear 5124 to rotate through the meshing structure. When the driven bevel gear 5124 rotates, it can drive the rotating rod 5123 to rotate inside the bearing housing 5122. When the rotating rod 5123 rotates, it can drive the end plate 5113 to rotate.

[0056] The telescopic part 52 includes an assembly base 521 connected to the bottom side of the end of the extruder body 2, a first telescopic rod 522 connected to the upper surface of the assembly base 521 and connected to the assembly plate 5121, and a first guide mechanism 523 disposed between the assembly plate 5121 and the assembly base 521. In this embodiment, when the first telescopic rod 522 is running, it can drive the assembly plate 5121 to move laterally. When the assembly plate 5121 moves laterally, it can drive the extruder head rotating mechanism 511 to move laterally, thereby adjusting the lateral position of the extruder head rotating mechanism 511.

[0057] The first guiding mechanism 523 includes a guide groove 5231 formed on the upper surface of the inner sidewall of the mounting base 521, and a guide block 5232 connected to the side surface of the mounting plate 5121 and adapted to the guide groove 5231. In this embodiment, when the mounting plate 5121 is subjected to a force, it can drive the guide block 5232 to slide inside the guide groove 5231, thereby limiting the movement direction of the mounting plate 5121 and maintaining the stability of the movement.

[0058] When in use, the first telescopic rod 522 extends and drives the assembly plate 5121 to move laterally. When the assembly plate 5121 moves laterally, it drives the extruder head rotation mechanism 511 to move laterally away from the discharge port of the extruder body 2.

[0059] Next, the drive motor 5125 is controlled to run. When the drive motor 5125 runs, it drives the active bevel gear 5126 to rotate and drives the rotating rod 5123 to rotate through the driven bevel gear 5124. When the rotating rod 5123 rotates, it drives the end plate 5113 to rotate on the inner wall of the outer ring 5111. When the end plate 5113 rotates to -60°, -30°, 30° and 60°, it can align the extrusion holes 5114 of different shapes with the discharge port of the extruder body 2.

[0060] Finally, the first telescopic rod 522 is controlled to retract. When the first telescopic rod 522 retracts, it drives the extrusion head rotation mechanism 511 to move towards the discharge port of the extruder body 2 through the assembly plate 5121 until the end plate 5113 presses against its side surface. This allows for the processing of trolley case rubber strips with different cross-sectional shapes.

[0061] It should be noted that the first telescopic rod 522 and the drive motor 5125 can be controlled by a PLC control system.

[0062] Example 2

[0063] like Figure 7 - Figure 8 Embodiment 2 of the present invention is shown, which differs from Embodiment 1 above only in that: a monitoring and cutting assembly 6 is installed on the surface of the outer ring 5111. The monitoring and cutting assembly 6 includes a cutting part 61 installed on the top of the outer ring 5111 and a sensing probe 62 installed on the bottom side surface of the outer ring 5111 and vertically upward.

[0064] The cutting section 61 includes a first upright plate 611 connected to the top of the outer ring 5111, a second telescopic rod 612 mounted on the side surface of the first upright plate 611, a docking plate 613 connected to the telescopic end of the second telescopic rod 612, and a cutter 614 disposed on the side surface of the docking plate 613 and connected by a clamping mechanism 615. In this embodiment, when the second telescopic rod 612 extends, it can drive the docking plate 613 to move longitudinally. The longitudinal movement of the docking plate 613 can drive the cutter 614 to move longitudinally through the clamping mechanism 615, thereby adjusting the position of the cutter 614.

[0065] The clamping mechanism 615 includes a circular hole 6151 formed on the surface of the second telescopic rod 612, a first crossbar 6152 passing through the circular hole 6151 and connected to the side surface of the cutter 614, a limiting block 6153 connected to the end of the first crossbar 6152, and a spring strip 6154 connected between the second telescopic rod 612 and the cutter 614 and sleeved on the surface of the first crossbar 6152. In this embodiment, the spring strip 6154 can compress the cutter 614 with its own elastic force, and the cutter 614 can be pressed tightly against the outer surface of the end plate 5113 when compressed.

[0066] In use, the extruded suitcase rubber strip can be monitored by the sensor 62. When the suitcase rubber strip monitored by the sensor 62 curls, the sensor 62 controls the extension of the second telescopic rod 612 through the sensor switch. When the second telescopic rod 612 extends, it drives the docking plate 613 to move downward. When the docking plate 613 moves downward, it drives the cutter 614 to move downward through the clamping mechanism 615. The downward movement of the cutter 614 can cut the suitcase rubber strip, thereby removing the unqualified suitcase rubber strip.

[0067] After the cutting is completed, the second telescopic rod 612 retracts and drives the cutter 614 to retract through the docking plate 613 and the clamping mechanism 615, thereby realizing the reset of the cutter 614.

[0068] It should be noted that the sensing probe 62 can be controlled by a PLC control system, which drives the sensing switch and controls the operation of the second telescopic rod 612.

[0069] Example 3

[0070] like Figure 9 - Figure 12 Embodiment 3 of the present invention is shown, which differs from Embodiment 2 above only in that: the cooling assembly 7 includes a base frame 71 provided at the bottom for support, a cooling pool 72 connected to the top of the base frame 71, a conveying roller 73 installed on the inner wall of the cooling pool 72 and provided at both ends, and a pressure roller portion 74 installed on the inner wall of the cooling pool 72 and extending to the outer side.

[0071] The pressure roller section 74 includes a second vertical plate 741 disposed inside the cooling pool 72, a pressure roller mechanism 742 mounted on the side surface of the second vertical plate 741 and arranged linearly at equal intervals, a third telescopic rod 743 mounted on the outer surface of the cooling pool 72 and connected to the second vertical plate 741, and a second guide mechanism 744 disposed between the cooling pool 72 and the second vertical plate 741. In this embodiment, when the third telescopic rod 743 is running, it can drive the second vertical plate 741 to move longitudinally. When the second vertical plate 741 moves longitudinally, it can drive the pressure roller mechanism 742 to move longitudinally, thereby adjusting the height of the pressure roller mechanism 742.

[0072] The second guiding mechanism 744 includes a guide rail 7441 connected to the inner wall of the cooling pool 72, and a guide sleeve 7442 connected to the side surface of the second upright plate 741 and adapted to the guide rail 7441. In this embodiment, when the second upright plate 741 is subjected to a force, it can drive the guide sleeve 7442 to slide on the surface of the guide rail 7441, which can limit the movement direction of the second upright plate 741 and maintain the stability of the movement.

[0073] The pressure roller mechanism 742 includes a second crossbar 7421 connected to the side surface of the second vertical plate 741, a bearing ring 7422 sleeved on the surface of the second crossbar 7421, and a pressure roller 7423 connected to the outer surface of the bearing ring 7422.

[0074] In use, first, water is injected into the cooling pool 72. Then, the rubber strip of the trolley case is pulled out, passes through the bottom of the pressure roller mechanism 742, and falls onto the upper surface of the conveyor roller 73. Next, the third telescopic rod 743 can be controlled to retract. When the third telescopic rod 743 retracts, it can drive the second vertical plate 741 to move downward. When the second vertical plate 741 moves downward, it can drive the pressure roller mechanism 742 to move downward. When the pressure roller mechanism 742 moves downward, it can press the rubber strip of the trolley case into the water in the cooling pool 72, thereby cooling and shaping the rubber strip of the trolley case through the water.

[0076] This invention also relates to a method for extruding and molding rubber strips for suitcases, such as... Figure 13 As shown, it includes the following steps:

[0077] S1: Adjustment of the extrusion head of the trolley case rubber strip. Check and control the equipment of the extrusion molding equipment. Then, adjust the position of the extrusion head according to the shape of the trolley case rubber strip to be produced and processed by setting the extrusion head adjustment component 5.

[0078] S2: Raw material proportioning and mixing and drying: The main materials of the luggage rubber strip, such as PVC / TPE / TPU, plasticizer, stabilizer, lubricant, color masterbatch and filler, are added to the high-speed mixer in a quantitative manner and mixed. Then the mixed raw materials are sent to the dehumidifying dryer. Finally, the dried mixed raw materials are added to the hopper 3.

[0079] S3: The plasticizing and molding of the trolley case rubber strip is performed by the extruder. The raw material inside the hopper 3 enters the interior of the extruder body 2 and is melted and conveyed. Then the molten raw material is extruded through the extrusion hole 5114 to form the trolley case rubber strip.

[0080] S4: Monitoring and cutting of waste trolley case rubber strips. The extruded trolley case rubber strips are sensed by the sensor probe 62. When the extruded trolley case rubber strips curl and deform, the trolley case rubber strips are cut by the cutting part 61.

[0081] S5: Pulling and limiting of the luggage rubber strip. The standard luggage rubber strip is limited by the cooling component 7 and then connected to the pulling mechanism. The pulling mechanism pulls the rubber strip.

[0082] S6: Cooling and shaping of the luggage rubber strip. The luggage rubber strip is cooled and shaped by the internal water during the process of passing through the cooling component 7.

[0083] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
