Description

TECHNICAL FIELD

[0001] The present application relates to the field of tie-dyeing technology, in particular to a full hydraulic woodworking band saw running car. BACKGROUND

[0002] The band saw running car is composed of shaft, wheel and support frame. The band saw running car needs to run on two parallel tracks when moving. The band saw running car on the market is mostly manually operated or pneumatically controlled. In order to adapt to the use in low-temperature areas, a full hydraulic band saw running car has appeared.

[0003] The manually operated band saw running car needs a large number of workers and has high labor intensity. Some workers are close to the band saw blade when cutting wood, which has safety hazards.

[0004] The pneumatically controlled band saw running car overcomes the shortcomings of the manually operated band saw running car. However, a gas station needs to be arranged on site to supply gas to the equipment, which increases the cost and the site of the customer. Moreover, the gas is compressible, and the thermal expansion and cold contraction characteristics are obvious. The water vapor mixed in the air freezes at low temperature (below 0 degrees), which damages the pneumatic control elements and pneumatic execution elements, so that the equipment cannot operate normally.

[0005] Moreover, the adjustment of the existing woodworking band saw running car is achieved by the hook extension movement, the structure is relatively complex, and the gap is large. When the car is swinging, the vibration amplitude of the band saw running car is large. SUMMARY

[0006] The purpose of the present application is to provide a full hydraulic woodworking band saw running car to solve the problems in the background.

[0007] To achieve the above purpose, the present application provides the following technical solutions:

[0010] The adjustment pile comprises a footage pile, a pile cylinder and an extension cylinder. The extension directions of the pile cylinder and the extension cylinder are perpendicular to each other. The extension cylinder is connected with an upper clamping hook and a lower clamping hook at both ends. The pile cylinder is provided with a pile at the output end. The pile cylinder drives the pile to move close to or away from the upper and lower clamping hooks.

[0012] The hydraulic cylinder comprises parallelly connected execution hydraulic cylinders and buffer hydraulic cylinders.

[0013] The output end of the execution hydraulic cylinder is used for being connected with a load.

[0014] The output end of the buffer hydraulic cylinder is connected with a spring seat moving in a spring guide sleeve, and a buffer spring is connected between the spring guide sleeve and the spring seat.

[0015] A detection element is used for detecting the elastic force of the buffer spring.

[0016] The hydraulic control system controls the on-off of the A port connecting oil pipe and the B port connecting oil pipe according to the feedback information of the detection element.

[0023] Preferably, an operation console is installed on the base frame, and the operation console is internally provided with a protective net and a seat.

[0024] Preferably, the telescopic oil cylinder is slidingly connected with the footage pile along the vertical telescopic direction thereof.

[0025] Compared with the prior art, the present application has the following beneficial effects:

[0026] The change of the buffer spring pressure makes the hydraulic cylinder have elastic force, so that the execution element is the hydraulic cylinder, and "hard collision" between mechanisms is avoided; the execution hydraulic cylinder has elasticity, the thrust of the execution hydraulic cylinder is adjusted, the actual working condition and use requirement are met, and the stability and ease of use of the equipment are improved.

[0047] 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.

[0048] like Figures 1-2 As shown, the band saw trolley is composed of a trolley wheel assembly 1, a trolley swing assembly 3, a tilting assembly 4, a advancing stake assembly 5, an adjusting top stake 6, an advancing / retreating gear transmission assembly 7, a hydraulic control assembly 8, a trolley driving assembly 9, a protective net 10, an operating console 11, and a seat 12. This solution mainly improves the trolley swing assembly 3, the adjusting top stake 6, and the hydraulic control assembly 8. The other structures are existing technologies and will not be described in detail.

[0049] The sports car wheel assembly 1 is driven by the sports car driving assembly 9, which is responsible for the movement of the band saw sports car, enabling it to move forward and backward.

[0050] The inching pile assembly 5 is used to support the wood during sawing and is responsible for the control of the size of the sawn board, and is driven by the inching and retracting gear assembly 7.

[0051] The turnover assembly 4 is used to rotate and adjust the wood to the appropriate direction during sawing of the first face and to turn over the wood during sawing of the second face.

[0052] The adjusting pile 6 is used to adjust the size of the head during sawing of the first face and to serve as the support of the short hook during sawing of the second face.

[0053] The protective net 10 provides safety protection for the operator.

[0054] The operation console 11 is the window for human-computer interaction, and the operator controls the equipment through the console.

[0055] The structure of the adjusting pile 6 is shown in Figures 3-5

[0056] The adjusting pile 6 includes an inching pile 61, a pile oil cylinder 62, a pile 63, a telescopic oil cylinder 64, an upper clamping hook 65, and a lower clamping hook 66.

[0057] The telescopic oil cylinder 64 is connected to the rear side wall of the inching pile 61 through a sliding block sliding rail assembly along the vertical direction of its extension, the upper clamping hook 65 and the lower clamping hook 66 are distributed and fixed on the two ends of the telescopic oil cylinder 64, and the upper clamping hook 65 and the lower clamping hook 66 are fixed horizontally relative to the inching pile 61 through the driving of the telescopic oil cylinder 64.

[0058] The pile 63 is connected to the front side wall of the inching pile 61 through a sliding block sliding rail assembly along the horizontal direction, and the two ends of the pile oil cylinder 62 are connected to the pile 63 and the inching pile 61, respectively.

[0059] The working principle of the adjusting pile 6 is as follows:

[0060] As shown in Figure 5 , when sawing the first face of the wood, the horizontal distance between the tips of the upper clamping hook 65 and the lower clamping hook 66 and the left side wall of the pile 63 is large, which is called a long hook; when sawing the second face of the wood, the horizontal distance between the tips of the upper clamping hook 65 and the lower clamping hook 66 and the left side wall of the pile 63 is small, which is called a short hook; the long hook or the short hook can be realized by moving the pile 63 horizontally through the pile oil cylinder 62, and the pile 63 can support and limit the wood.

[0061] When the wood is placed between the upper clamping hook 65 and the lower clamping hook 66, the telescopic oil cylinder 64 is shortened to drive the upper clamping hook 65 and the lower clamping hook 66 to approach each other to clamp and fix the upper and lower sides of the wood. ​

[0062] The role of the top stake 63:

[0063] Adjusting the size of the head, when the size of the head is cut, the wood head is moved outward by the top stake 63 to achieve central cutting and improve the yield.

[0064] Adjusting the length of the hook, such as Figure 5 As shown, this method is compact and simple. The traditional method is to achieve the length of the hook by the upper clamping hook 65 and the lower clamping hook 66, which is relatively complex in structure and has a large gap.

[0065] The structure of the car swing assembly 3 is shown in Figures 6-9 :

[0066] The car swing assembly 3 includes a guide plate 31, a push plate 32, a linear slide 33, a linear guide rail 34, and a pull rod 35. The guide plate 31 has a special-shaped sliding groove 311.

[0067] The guide plate 31 is relatively fixed on the base frame 2, the linear guide rail 34 is relatively fixed on the car wheel assembly, the push plate 32 is rotatably installed with a roller shaft bearing, the roller shaft bearing relatively rolls in the special-shaped sliding groove 311, the push plate 32 is fixed on the linear slide 33, and the linear slide 33 linearly slides on the linear guide rail 34. One end of the pull rod 35 is connected with the push plate 32, and the other end is connected with the hydraulic control assembly 8. The pull rod 35 (driven by the related control oil cylinder) is equivalent to the load 814 in the hydraulic control assembly 8.

[0068] The working principle of the car swing assembly 3:

[0069] The extension of the hydraulic control assembly 8 drives the linear slide 33 to linearly slide on the linear guide rail 34. During this process, the roller shaft bearing relatively rolls along the track in the special-shaped sliding groove 311. Due to the relative offset of the track of the special-shaped sliding groove 311 to the moving direction of the linear slide 33, the guide plate 31 moves in the other direction relative to the linear guide rail 34, so as to realize that the wood on the band saw car retreats a distance relative to the saw blade, ensuring that the wood does not contact the saw blade during the return stroke. Compared with the previous oil cylinder or air cylinder straight pushing mechanism, the vibration is greatly reduced, greatly improving the operation comfort.

[0070] The band saw car needs to have an empty return stroke after the working stroke. When the band saw car starts to return, the car frame needs to retreat a distance relative to the saw blade to avoid friction or collision between the saw blade and the log surface, causing damage to the saw blade or accidental disengagement of the saw wheel. The existing car swing device is a spiral friction type car swing device, which is complex in structure and easy to damage, requiring regular debugging and maintenance, increasing the labor intensity of workers and reducing production efficiency.

[0071] The structure of the hydraulic control assembly 8 is shown in Figures 10-12 :

[0072] Buffer hydraulic cylinder 81 is connected with spring guide 84 through spring guide connector 82, so that buffer hydraulic cylinder 81 and spring guide 84 are fixed relative to each other;

[0073] As shown in the drawings, the output end (piston rod 86 free end) of buffer hydraulic cylinder 81 is provided with spring seat 87, spring seat 87 slides linearly inside spring guide 84, adjusting bolt 85 is threadedly connected with spring guide 84, the left end of adjusting bolt 85 is movably connected with adjusting end spring seat 89 inside spring guide 84, buffer spring 88 is connected between spring seat 87 and adjusting end spring seat 89; Figure 11

[0074] Detection element 83 is installed on spring guide 84, detection element 83 can adopt proximity switch or pressure sensor or grating ruler (all are existing products); detection element 83 is used for detecting the compression amount of buffer spring 88, so that the elastic force of buffer spring 88 can be calculated.

[0075] As shown in the drawings, hydraulic control system is not shown in the drawings, and is not described in detail, hydraulic control system, A port connecting oil pipe 817, buffer hydraulic cylinder 81 / execution hydraulic cylinder 812, B port connecting oil pipe, hydraulic control system are sequentially connected to form a closed loop; Figure 12

[0076] The connecting port of hydraulic control system and A port connecting oil pipe 817 is set as A port;

[0077] The connecting port of hydraulic control system and B port connecting oil pipe 816 is set as B port.

[0078] State 1 of elastic hydraulic cylinder 100:

[0079] Hydraulic oil with pressure is injected from A port of buffer hydraulic cylinder 81, piston rod 86 is driven to move to the direction of B port of buffer hydraulic cylinder 81, at this time, corresponding hydraulic oil flows out from B port of buffer hydraulic cylinder 81, and then piston rod 86 pushes spring seat 87 at the free end of piston rod 86, and spring seat 87 pushes buffer spring 88 to compress (less than the working stroke of buffer spring 88). When the pushing force generated by the hydraulic oil injected from A port of buffer hydraulic cylinder 81 is equal to the pressure generated by the compression of buffer spring 88, the device is in a balanced state.

[0080] State 2 of elastic hydraulic cylinder 100: when the pressure of hydraulic oil injected from A port of buffer hydraulic cylinder 81 increases, more hydraulic oil is injected from A port of buffer hydraulic cylinder 81, at this time, corresponding hydraulic oil also flows out from B port of buffer hydraulic cylinder 81, and buffer spring 88 is continuously compressed (less than the working stroke of buffer spring 88), until the pressure generated by the compression of buffer spring 88 is equal to the pushing force of buffer hydraulic cylinder 81, and the balanced state is reached again. ​​

[0081] State 3 of elastic hydraulic cylinder 100: when the hydraulic oil pressure injected into port A of buffer hydraulic cylinder 81 decreases, the pressure generated by compression of buffer spring 88 is greater than the thrust of buffer hydraulic cylinder 81, and buffer spring 88 pushes piston rod 86 to move toward port A of buffer hydraulic cylinder 81. At this time, port B of buffer hydraulic cylinder 81 is filled with oil, and port A is drained. Then, the pressure of port A of buffer hydraulic cylinder 81 increases until it is equal to the pressure generated by compression of buffer spring 88, and the device reaches a balanced state again.

[0082] In the above adjustment process to reach a balanced state, the compression amount of buffer spring 88 can be adjusted by adjusting bolt 85 against adjustment end spring seat 89, so that the pressure of buffer spring 88 increases or decreases. When the device reaches a balanced state, the pressure of port A of buffer hydraulic cylinder 81 is adjusted.

[0083] In the above adjustment process to reach a balanced state, spring guide sleeve 84 can also be slotted and equipped with detection element 83. Detection element 83 detects the distance that spring seat 87 is pushed out by buffer hydraulic cylinder 81. When it is detected that spring seat 87 reaches a corresponding position, that is, the corresponding compression amount of buffer spring 88, detection element 83 sends an electrical signal. In cooperation with the hydraulic control system, the inlet and outlet oil paths of buffer hydraulic cylinder 81 are cut off, so that the device reaches a balanced state, and the purpose of pressure adjustment is achieved.

[0084] Principle of hydraulic control assembly 8:

[0085] Buffer hydraulic cylinder 81 and at least one group of A and B ports of execution hydraulic cylinder 812 in elastic hydraulic cylinder 100 are connected in parallel through B port connecting oil pipe 816 and A port connecting oil pipe 817, respectively. The output end of execution hydraulic cylinder 812 is connected to the respective load 814. Port A is connected to one end of the hydraulic control system through A port connecting oil pipe 817, and port B is connected to the other end of the hydraulic control system through B port connecting oil pipe 816, to transport hydraulic oil and control the direction and on-off of oil.

[0086] When the hydraulic control system injects hydraulic oil with pressure into the A port of the buffer hydraulic cylinder 81 and the A port of the execution hydraulic cylinder 812 through the connecting oil pipe 817, the execution hydraulic cylinder 812 will extend with the corresponding load 814, and because of the parallel connection, the buffer hydraulic cylinder 81 will also compress the buffer spring 88 under pressure. When the buffer spring 88 is compressed to the position set by the detection element 83 (this position can be adjusted to adjust the compression amount of the compression spring and further adjust the force of the execution hydraulic cylinder 812), the detection element 83 gives an electrical signal, and the hydraulic control system receives the signal and closes the A port and the B port. At this time, the hydraulic oil in the system composed of the parallelly connected buffer hydraulic cylinder 81 and the execution hydraulic cylinder 812 cannot flow in and out of the A port and the B port, but only flows in the cylinders in the system, that is, a closed space is formed between the buffer hydraulic cylinder 81 and the execution hydraulic cylinder 812. At the same time, the force generated by the load 4 is transmitted to the buffer spring 88 through the hydraulic oil (which is incompressible) in the pipeline, and the pressure of the buffer spring 88 reaches a balanced state (state 1).

[0087] When the force of the load 814 increases (which can be increased alone or simultaneously), the execution hydraulic cylinder 812 retracts, the hydraulic oil flows out of the A port of the execution hydraulic cylinder 812, flows into the A port of the buffer hydraulic cylinder 81 through the pipeline, the buffer hydraulic cylinder 81 extends to compress the buffer spring 88, the hydraulic oil flows out of the B port of the buffer hydraulic cylinder 81 and flows into the B port of the execution hydraulic cylinder 812, and when the force of the load 814 and the pressure of the buffer spring 88 reach a balance, the oil stops flowing, and the balance is reached again (state 2).

[0088] When the force of the load 814 decreases (which can be decreased alone or simultaneously), the balance can also be reached again (state 3), and the hydraulic oil flows in the opposite direction.

[0089] The pile driving cylinder 62 and the telescopic cylinder 64 can also be replaced by the hydraulic control assembly 8, so that the upper clamping hook 65 and the lower clamping hook 66 have a certain elastic force when they cooperate to clamp the wood, and the pile 63 has a certain elastic force when it is driven in and out to avoid rigid impact.
