Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment, in particular to a servo filling and lifting mechanism of a hose tail sealing machine. Background Art

[0002] The hose sealing machine is a mechanical device that uses a fully automatic control system to supply, fill, and seal plastic hoses, composite tubes, and other tubular containers during the filling process. During the operation of the hose sealing machine, the hose rotates from the station turntable to the filling station. During filling, the hose needs to be lifted and the material needs to be squeezed into the hose. The lifting and filling mechanisms of existing hose sealing machines usually use a power mechanism to drive a cam mechanism to achieve periodic lifting / squeezing operations.

[0003] For example, CN210364617U discloses a plastic hose tail sealing machine. During filling, the material control motor starts to drive the cam to rotate, and the rotation of the cam drives the lifting rod to move up and down. The up and down movement of the lifting rod drives the hinged control block to rotate, and the rotation of the control block drives the valve core to rotate, ensuring that the material first enters the metering pump from the storage device, and then is pressed into the filling device through the metering pump, and then injected into the hose through the filling device.

[0004] The plastic hose tail sealing machine is designed in this way, using the cam mechanism to provide power. In the actual filling process, since the stroke of the cam is fixed, the stroke of the power rod driven by the cam is also fixed. When the filling or lifting stroke needs to be adjusted, the entire set of cam mechanisms needs to be replaced as a whole. At the same time, since the cam stroke is fixed, variable speed operation is not possible. In this case, when it is necessary to fill and seal hoses of different diameters and lengths, the entire set of cam mechanisms needs to be replaced to adjust the stroke of the power rod. The overall replacement operation requires shutdown, and the replacement process is complicated.

[0005] Therefore, how to further improve the filling and lifting structure of the existing hose tail sealing machine has become the focus of current design. Utility Model Content

[0006] The technical problem to be solved by the utility model is: in order to overcome the deficiencies of the prior art, the utility model provides a servo filling and lifting mechanism for a hose tail sealing machine, which can conveniently and quickly adjust the action of a power rod in the lifting and extrusion mechanism without stopping the machine to disassemble the entire transmission mechanism, and can conveniently switch the power rod stroke for hoses of different lengths and diameters using the same hose tail sealing machine.

[0007] The technical solution adopted by the utility model to solve the technical problem is: a servo filling and lifting mechanism of a hose tail sealing machine, which is arranged in the body of the hose tail sealing machine, and includes a lifting device and a filling device. It is used to lift the hose upward and fill the material into the hose. The lifting device includes a lifting power rod, a crank connecting rod mechanism and a lifting power device. The lifting power device drives the lifting slider mechanism to drive the lifting power rod to reciprocate and provide power for lifting the hose upward; the filling device includes a filling power rod, a crank slider mechanism and a filling power device. The filling power device drives the crank slider mechanism to drive the filling power rod to reciprocate and provide power for filling the material into the hose.

[0008] In the above scheme, compared with the traditional cam mechanism, the crank-connecting rod mechanism and the crank slider mechanism are used to drive the corresponding power rod to perform reciprocating motion. During adjustment, it is only necessary to adjust the output of the corresponding power device to adjust the reciprocating stroke and frequency of the crank-connecting rod mechanism and the crank slider mechanism accordingly, thereby achieving adjustment and adaptation to hoses of different specifications.

[0009] Furthermore, the crank connecting rod mechanism includes a first lifting connecting rod, a second lifting connecting rod and a lifting crank. The output end of the lifting power device is connected to the first lifting connecting rod and drives the first lifting connecting rod to rotate back and forth. The first lifting connecting rod is provided with a waist-shaped groove. One end of the second lifting connecting rod is hinged to the machine body, and the other end is fixed with a matching block. The matching block is slidably arranged in the waist-shaped groove. One end of the lifting crank is hinged to the lifting power rod, and the other end is hinged to the end of one side of the lifting second connecting rod with the matching block. When working, the lifting power device drives the lifting power rod to move through the crank connecting rod mechanism, which can move the lifting feeding structure above it, and realize the upward feeding operation of the hose located at the filling station.

[0010] Furthermore, the crank slider mechanism includes a filling connecting rod, a filling crank, a filling slider and a filling track. The output end of the filling power device is connected to one end of the filling connecting rod and drives the filling connecting rod to rotate back and forth. The other end of the filling connecting rod is hinged to one end of the filling crank, and the other end of the filling crank is hinged to the filling slider. The filling track is fixedly arranged in the body along the output direction of the filling power rod. The filling slider is slidably matched with the filling track, and the filling power rod is fixed to the filling slider. When working, the filling power device drives the filling power rod to reciprocate, provides extrusion pressure for the filling extrusion device, and realizes the filling operation.

[0011] Preferably, the lifting power device and the filling power device are both servo motors. The forward and reverse rotation of the servo motor can drive the corresponding power rod to reciprocate, and the reciprocating stroke and frequency of the corresponding power rod can be adjusted by adjusting the output of the servo motor, so as to meet the filling and lifting requirements of hoses of different specifications and sizes.

[0012] The beneficial effect of the utility model is that the servo filling and lifting mechanism of the hose tail sealing machine provided by the utility model utilizes a servo motor to drive a crank slider and a crank connecting rod mechanism, and the servo motor can be used to adjust the stroke of the slider and the connecting rod, thereby adjusting the stroke of the power rod of the filling mechanism and the lifting mechanism, which is convenient for adjusting and switching operations corresponding to hoses of different lengths and diameters, without the need to disassemble the entire set of mechanisms, and the adjustment process is convenient and quick.

DETAILED DESCRIPTION

[0019] The utility model is now described in further detail in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, so they only show the components related to the utility model, and the directions and references (for example, up, down, left, right, etc.) can only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not adopted in a restrictive sense, and the scope of the subject matter claimed is limited only by the attached claims and their equivalents.

[0020] like Figures 1 to 3The servo filling and lifting mechanism of the hose tail sealing machine shown is the best embodiment of the utility model. A station turntable with indexing rotation is provided in the body of the hose tail sealing machine. The hoses to be filled are arranged on the station turntable at equal intervals and rotated to the filling station with indexing. The servo filling and lifting is arranged in the body of the hose tail sealing machine, including a lifting device and a filling device. During filling, the lifting device is used to lift the hose upward, and the filling device simultaneously fills the material into the hose when lifting the hose.

[0021] The lifting device includes a lifting power rod 3, a crank connecting rod mechanism and a lifting power device 8. The lifting power device 8 preferably adopts a servo motor, and the servo motor drives the lifting slider mechanism to drive the lifting power rod 3 to reciprocate. The filling device includes a filling power rod 9, a crank slider mechanism and a filling power device 14. The filling power device 14 also preferably adopts a servo motor, and the servo motor drives the reducer to drive the filling power rod 9 to reciprocate.

[0022] Specifically, the reciprocating motion of the lifting power rod 3 is realized by a crank connecting rod mechanism in cooperation with a servo motor. The crank connecting rod mechanism includes a first lifting connecting rod 4, a second lifting connecting rod 5 and a lifting crank 6. After the servo motor drives the reducer, the output end of the reducer is connected to the first lifting connecting rod 4 and drives the first lifting connecting rod 4 to reciprocate. A waist groove 15 is provided on the first lifting connecting rod 4. One end of the second lifting connecting rod 5 is hinged to the machine body, and the other end is fixed with a matching block 7. The matching block 7 is slidably arranged in the waist groove 15. One end of the lifting crank 6 is hinged to the lifting power rod 3, and the other end is hinged to one side end of the second lifting connecting rod 5 having the matching block 7. During operation, the first lifting link 4 reciprocates under the drive of the servo motor, and the matching block 7 drives the second lifting link 5 to rotate around the hinge point under the limit of the waist groove 15. At this time, the lifting crank 6, one end of which is hinged on the second lifting link 5, moves, and the lifting crank 6 then drives the lifting power rod 3 hinged thereto to move. When the lifting power rod 3 moves, the lifting feeding structure above it can move, and the upward feeding operation of the hose at the filling station can be realized.

[0023] The reciprocating motion of the filling power rod 9 is realized by a crank slider mechanism in conjunction with a servo motor. The crank slider mechanism includes a filling connecting rod 10, a filling crank 11, a filling slider 12 and a filling track 13. After the servo motor drives the reducer, the output end of the reducer is connected to one end of the filling connecting rod 10 and drives the filling connecting rod 10 to reciprocate, the other end of the filling connecting rod 10 is hinged to one end of the filling crank 11, and the other end of the filling crank 11 is hinged to the filling slider 12. The filling track 13 is fixedly arranged in the body along the output direction of the filling power rod 9, the filling slider 12 is slidably matched with the filling track 13, and the filling power rod 9 is fixed to the filling slider 12. During operation, the servo motor drives the filling connecting rod 10 to reciprocate, at which time the other end of the filling connecting rod 10 drives the filling crank 11 hinged thereto to move, and when the filling crank 11 moves, it synchronously drives the filling slider 12 to reciprocate. Since the filling slider 12 is slidably arranged on the filling track 13, under the limiting effect of the filling track 13, the filling slider 12 performs reciprocating sliding motion along the filling track 13. At this time, the filling power rod 9 fixed to the filling slider 12 is driven by the slider to reciprocate synchronously. The filling power rod 9 provides extrusion pressure for the filling extrusion device to realize the filling operation.

[0024] In the filling and lifting mechanism of the original hose tail sealing machine, a cam mechanism is used for lifting. If this structure needs to change the hose specifications, that is, hoses of different lengths, the cam needs to be replaced as a whole. This method is very time-consuming and labor-intensive, and the cam needs to be replaced as a whole. Secondly, the cam stroke is fixed and cannot be changed. In this embodiment, the lifting power device 8 and the filling power device 14 are both servo motors, which drive the reducer through the servo motor to drive the corresponding connecting rod for transmission. The servo motor can be reversed as needed, and the output can be adjusted. This structure does not need to be disassembled and replaced when changing production. The parameters of the servo motor, such as the electronic cam curve, can be directly adjusted, and the speed can be changed at any time. The corresponding power rod can be driven to reciprocate by the forward and reverse rotation of the servo motor. The output adjustment of the servo motor realizes the adjustment of the reciprocating motion stroke and frequency of the corresponding power rod, which is convenient for responding to the filling and lifting requirements of hoses of different specifications and sizes.

[0025] Through the cooperation of the servo motor with the crank connecting rod mechanism and the crank slider mechanism, the lifting stroke and lifting frequency of the jacking power rod 3 and the filling power rod 9 can be adjusted by adjusting the output of the servo motor. The lifting stroke of the jacking power rod 3 can be adjusted according to the size of the filling hose to adapt to the hose specifications. The lifting frequency of the filling power rod 9 can be adjusted according to the filling extrusion requirements. In this way, compared with the traditional cam structure, the filling mechanism and the jacking mechanism can be adjusted according to the actual hose specifications and filling requirements by adjusting the two servo motors without disassembling the cam. The adjustment process is convenient, fast, reliable and effective.

[0026] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
