However, the device does not have a bearing structure, and when the device is completed, the pultrusion machine may still be discharging, and the pulled material may fall under its own gravity, and the synchronously pulled material may contact or even entangle. UTILITY MODEL CONTENTS

[0005] In order to solve the above problems, the utility model provides a traction mechanism of pultrusion machine, which adopts the following technical scheme:

[0006] A traction mechanism of pultrusion machine, comprising a bottom frame, the bottom frame is fixedly installed with a stand at the bottom of each corner, the bottom of each stand is provided with a driving wheel, the bottom of the bottom frame is provided with a lifting support assembly, the bottom frame is slidably installed with a base, the bottom frame is fixedly installed with two symmetrically distributed support rods, one end of each support rod is slidably penetrated through the base, a driving assembly is arranged between the base and the bottom frame, the top of the base is fixedly installed with a frame, the frame is provided with a clamping assembly, the frame is fixedly installed with a mounting bracket on one side, and a pressing assembly is arranged between the opposite side of the mounting bracket and the frame.

[0007] A support plate is provided above the bottom frame, and the top of the support plate has multiple grooves arranged in a straight array. Support blocks are slidably fitted on the side walls of the two support rods, and the tops of the two support blocks are fixedly connected to the bottom of the support plate.

[0008] By adopting the above technical solution, the equipment can be moved by the operator using the drive wheels, which improves the equipment's convenience. Once the equipment is in the appropriate position, the lifting support assembly raises the base frame, lifting the drive wheels off the ground and providing stable support for the base frame. This helps maintain the stability of the equipment and allows for height adjustment, facilitating docking with pultrusion machines of different heights. After docking, the operator places one end of the material inside the frame, clamps it using the clamping assembly, and then presses the end of the material to secure it using the pressing assembly. The combination of clamping and pressing components improves the stability of material clamping. After the material is clamped, the drive component drives the base to move synchronously with the frame, thereby pulling the material. The material slides in the groove at the top of the support plate when being pulled, thanks to the cooperation of the support block and the support plate. The support plate and the support block support the material, preventing the pulled-out material from falling and contacting the ground under gravity when the equipment stops pulling, or even getting tangled. The two support blocks slide on the side wall of the support rod, making it easy for the operator to adjust the position of the support plate.

[0009] Furthermore, the lifting support assembly includes two second cylinders fixedly installed at the bottom end of the base frame. The two second cylinders are symmetrically distributed at the bottom end of the base frame. A connecting block is fixedly installed at the end of the piston shaft of each of the two second cylinders. A base plate is fixedly installed at the bottom end of each of the two connecting blocks. Two symmetrically distributed stabilizing blocks are fixedly installed on both sides of each of the two base plates. Anti-slip pads are fixedly installed at the bottom ends of the base plates and the stabilizing blocks.

[0010] By adopting the above technical solution, when the equipment is moved to a suitable position, the connecting block and the base plate are driven to descend synchronously by the second cylinder, and the base plate contacts the ground. Then, the bottom frame is raised by the driving force of the second cylinder, thereby causing the drive wheel to leave the ground. The base plate is equipped with stabilizing plates on both sides, which can play a balancing role, thus supporting and stabilizing the equipment, which helps to maintain the stability of the equipment. It can also adjust the height of the equipment, making it easy to connect the equipment with pultrusion machines of different heights.

[0011] Furthermore, the drive assembly includes a screw rotatably mounted in the base frame, the screw being located between the two support rods, the base being sleeved on the side wall of the screw, a geared motor being fixedly mounted on one side of the base frame, one end of the screw penetrating the base frame and being fixedly connected to the output shaft end of the geared motor, and a plurality of rollers arranged in a linear array being rotatably mounted on the bottom end of the base.

[0012] By adopting the above technical solution, after the material is clamped, the screw is driven to rotate by the geared motor, which causes the base and frame to move synchronously, thus playing the role of pulling the material. When the base moves, it slides on the two support rods, which helps to maintain the stability of the base moving with the frame. In addition, the rollers at the bottom of the base help to maintain the smoothness of the base movement.

[0013] Furthermore, the clamping assembly includes a placement block fixedly installed on the inner wall of the bottom end of the frame. The top of the placement block has a placement groove arranged in a linear array. A lifting block is slidably installed inside the frame. Below the lifting block, there are multiple pressing plates arranged in a linear array. The pressing plates are arranged one-to-one with the placement grooves. The bottom end of each pressing plate has a pressing groove. The bottom end of the lifting block has multiple sets of movable grooves arranged in a linear array. There are two movable grooves in the same set, and they are symmetrically distributed with the bottom end of the lifting block. A support rod is slidably installed in each movable groove. A spring is fixedly connected between the top end of the support rod and the inner wall of the top end of the movable groove in the same set. The bottom ends of the two support rods in the same set are fixedly connected to the top ends of the pressing plates in the same set. A first cylinder is fixedly installed at the top end of the frame. The piston shaft of the first cylinder slides through the frame and is fixedly connected to the top end of the lifting block.

[0014] By adopting the above technical solution, the worker places one end of the material into the placement slot at the top of the placement block. Then, the first cylinder drives the lifting block and the pressing plate to descend synchronously, causing the pressing plate to move into the same placement slot. Through the cooperation of the pressing plate and the placement slot, the material can be clamped. When the pressing plate contacts the side wall of the material, the pressing plate pushes the same support rod to slide in the same movable slot under the driving force of the first cylinder. The support rod pushes the same spring to contract, and the spring gives the support rod a rebound force, which can play a buffering role. Through the cooperation of the support rod and the spring, the pressing plate can be located in different positions in the same placement slot, thus facilitating the equipment to clamp and fix materials of different sizes.

[0015] Furthermore, two symmetrically distributed limiting blocks are fixedly installed on the upper side wall of each support rod, and the inner wall of the movable groove is provided with a limiting groove that matches the limiting blocks in the same group.

[0016] By adopting the above technical solution, when the support rod slides in the movable groove, the support rod slides in the same set of limiting grooves with the limiting block. The cooperation between the limiting block and the limiting groove helps to maintain the stability of the support rod sliding and helps to prevent the support rod from leaving the movable groove.

[0017] Furthermore, the pressing assembly includes a first rubber pad fixedly installed on the side of the frame near the mounting bracket. The mounting bracket is provided with a mounting plate. A second rubber pad is fixedly installed on the side of the mounting plate near the base. Two telescopic rods are fixedly installed on the inner wall of the mounting bracket away from the frame. The ends of the two telescopic rods are fixedly connected to the side opposite to the mounting plate.

[0018] By adopting the above technical solution, the staff pulls one end of the material into the mounting frame, and then drives the mounting plate with the second rubber pad towards the base through the telescopic rod. The cooperation between the second rubber pad and the first rubber pad can press and fix the material, thereby further clamping and fixing the material, which helps to maintain the stability of the material when it is pulled.

[0019] In summary, this utility model has the following beneficial technical effects:

[0020] (1) In this utility model, the combination of the support block, the support plate and the groove facilitates the support and bearing of the pultruded material, which helps to prevent the material pulled out from falling under the action of gravity when the equipment stops pulling and causing entanglement.

[0021] (2) In this utility model, the clamping component is used to clamp and fix the material, and the combination of the pressing plate, the support rod and the spring makes it easy to clamp and fix materials of different sizes. The pressing component is used to press the end of the material, which helps to improve the stability of the material pulling and clamping.

[0022] (3) In this utility model, the device can be moved by the drive wheel, and by setting the lifting support component, the connecting block and the bottom plate are driven to fall synchronously by the second cylinder, thereby making the bottom frame and other structures rise synchronously, and the drive wheel is lifted off the ground, which can play the role of supporting and stabilizing the bottom frame, which is conducive to maintaining the stability of the equipment, and can also play the role of adjusting the height of the bottom frame, making it convenient for the equipment to dock and pull pultrusion machines of different heights.

[0033] The following is in conjunction with the appendixFigures 1-5 The present invention will be described in further detail below.

[0034] Please see Figures 1-5 A traction mechanism for a pultrusion machine includes a base frame 1. Columns 3 are fixedly installed at the four corners of the bottom end of the base frame 1. Each column 3 has a drive wheel at its bottom end. A lifting support assembly is provided at the bottom end of the base frame 1. The lifting support assembly includes two second cylinders 19 fixedly installed at the bottom end of the base frame 1, symmetrically distributed. Connecting blocks 20 are fixedly installed at the piston shaft ends of both second cylinders 19. Base plates 21 are fixedly installed at the bottom ends of both connecting blocks 20. Two symmetrically distributed stabilizing blocks are fixedly installed on both sides of the base plates 21. Anti-slip pads are fixedly installed at the bottom ends of the base plates 21 and the stabilizing blocks. When the equipment is in use, the operator can move the equipment by driving the drive wheels, which improves the convenience of the equipment. When the equipment is moved to the corresponding position, the connecting block 20 and the base plate 21 are driven to descend synchronously by the second cylinder 19, and the base plate 21 contacts the ground. Then, the bottom frame 1 is raised by the driving force of the second cylinder 19, which causes the drive wheels to leave the ground. The base plate 21 is equipped with stabilizing plates on both sides, which can play a balancing role, thus supporting and stabilizing the equipment, which helps to maintain the stability of the equipment. It can also adjust the height of the equipment, making it easy to connect the equipment with pultrusion machines of different heights.

[0035] A base 6 is slidably installed inside the base frame 1. Two symmetrically distributed support rods 2 are fixedly installed inside the base frame 1, with one end of each support rod 2 sliding through the base 6. A frame 16 is fixedly installed at the top of the base 6. A clamping assembly is provided inside the frame 16. The clamping assembly includes a placement block 10 fixedly installed on the inner wall of the bottom end of the frame 16. The top of the placement block 10 has placement slots 11 arranged in a linear array. A lifting block 14 is slidably installed inside the frame 16. Below the lifting block 14 are multiple pressing plates 12 arranged in a linear array. The pressing plates 12 are arranged one-to-one with the placement slots 11. Each pressure plate 12 has a pressing groove at its bottom end. The bottom end of the lifting block 14 has multiple sets of movable grooves 24 arranged in a linear array. There are two movable grooves 24 in the same set, which are symmetrically distributed with the bottom end of the lifting block 14. Each movable groove 24 has a support rod 13 slidably installed inside it. A spring 23 is fixedly connected between the top end of the support rod 13 and the inner wall of the top end of the movable groove 24 in the same set. The bottom ends of the two support rods 13 in the same set are fixedly connected to the top end of the pressing plate 12 in the same set. A first cylinder 15 is fixedly installed at the top end of the frame 16. The piston shaft of the first cylinder 15 slides through the frame 16 and is fixedly connected to the top end of the lifting block 14.

[0036] The staff places one end of the material into the placement groove 11 opened at the top of the placement block 10. Then, the lifting block 14 and the pressing plate 12 are driven to descend synchronously by the first cylinder 15, so that the pressing plate 12 moves into the same group of placement grooves 11. Through the cooperation of the pressing plate 12 and the placement groove 11, the material can be clamped. When the pressing plate 12 contacts the side wall of the material, under the driving force of the first cylinder 15, the pressing plate 12 pushes the same group of support rod 13 to slide in the same group of movable grooves (24), and the support rod 13 pushes the same group of spring 23 to retract. The spring 23 gives the support rod 13 a rebound force, which can play a buffering role. Through the cooperation of the support rod 13 and the spring 23, the pressing plate 12 can be located in different positions in the same group of placement grooves 11, which makes it easier for the equipment to clamp and fix materials of different sizes.

[0037] Two symmetrically distributed limiting blocks are fixedly installed on the upper side wall of the support rod 13. The inner wall of the movable groove 24 is provided with a limiting groove that matches the limiting blocks in the same group. When the support rod 13 slides in the movable groove 24, the support rod 13 slides in the limiting groove in the same group with the limiting blocks. The cooperation between the limiting blocks and the limiting groove helps to maintain the stability of the sliding of the support rod 13 and helps to prevent the support rod 13 from falling out of the movable groove 24.

[0038] A mounting bracket 9 is fixedly installed on one side of the frame 16, and a pressing component is provided between the mounting bracket 9 and the opposite side of the frame 16. The pressing component includes a first rubber pad 8 fixedly installed on the side of the frame 16 near the mounting bracket 9. A mounting plate 7 is provided inside the mounting bracket 9. A second rubber pad is fixedly installed on the side of the mounting plate 7 near the base 6. Two symmetrically distributed telescopic rods 22 are fixedly installed on the inner wall of the mounting bracket 9 away from the frame 16. The ends of the two telescopic rods 22 are fixedly connected to the opposite side of the mounting plate 7. When the worker pulls one end of the material into the mounting bracket 9, the telescopic rods 22 drive the mounting plate 7 to move towards the base 6 with the second rubber pad. Through the cooperation of the second rubber pad and the first rubber pad 8, the material can be pressed and fixed, which further clamps and fixes the material and helps to maintain the stability of the material when it is pulled.

[0039] A drive assembly is provided between the base 6 and the base frame 1. The drive assembly includes a screw 4 rotatably installed inside the base frame 1. The screw 4 is located between two support rods 2. The base 6 is sleeved on the side wall of the screw 4. A geared motor 5 is fixedly installed on one side of the base frame 1. One end of the screw 4 passes through the base frame 1 and is fixedly connected to the end of the output shaft of the geared motor 5. Multiple rollers arranged in a linear array are rotatably installed at the bottom of the base 6. After the material is clamped, the screw 4 is driven to rotate by the geared motor 5, thereby causing the base 6 to move synchronously with the frame 16, which can play the role of pulling the material. When the base 6 moves, the base 6 slides on the two support rods 2, which helps to maintain the stability of the base 6 moving with the frame 16. The setting of rollers at the bottom of the base 6 helps to maintain the smoothness of the movement of the base 6.

[0040] A support plate 17 is provided above the bottom frame 1, and multiple grooves arranged in a linear array are opened at the top of the support plate 17. Support blocks 18 are slidably sleeved on the side walls of the two support rods 2, and the tops of the two support blocks 18 are fixedly connected to the bottom of the support plate 17. Through the cooperation of the support blocks 18 and the support plate 17, the material slides in the grooves opened at the top of the support plate 17 when it is pulled and moved. Through the cooperation of the support plate 17 and the support blocks 18, the material is supported and carried, which helps to prevent the pulled material from falling and contacting under the action of gravity when the equipment stops pulling, or even from getting entangled. The two support blocks 18 are slidably sleeved on the side walls of the support rods 2, which makes it easy for the staff to adjust the position of the support plate 17.

[0041] The implementation principle of this utility model embodiment is as follows: When using the equipment, the operator can drive the equipment to move via the drive wheels, which improves the convenience of the equipment. After the equipment moves to the corresponding position, the lifting support assembly drives the base frame 1 to rise, thereby lifting the drive wheels off the ground and supporting and stabilizing the base frame 1, which helps maintain the stability of the equipment and can also adjust the height of the equipment, facilitating docking with pultrusion machines of different heights. After the equipment docking is completed, the operator places one end of the material in the frame 16, clamps the material using the clamping assembly, and then presses and fixes the end of the material using the pressing assembly. The combination of the holding component and the pressing component helps to improve the stability of material clamping. After the material is clamped, the base 6 is driven by the drive component to move synchronously with the frame 16, thereby pulling the material. With the cooperation of the support block 18 and the support plate 17, the material slides in the groove opened at the top of the support plate 17 when it is pulled. The cooperation of the support plate 17 and the support block 18 plays the role of supporting and bearing the material, which helps to prevent the pulled part of the material from falling and contacting under the action of gravity when the equipment stops pulling, or even causing entanglement. In addition, the two support blocks 18 are slidably sleeved on the side wall of the support rod 2, which makes it easy for the staff to adjust the position of the support plate 17.

[0042] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
